[0042] The present disclosure provides an intelligent garden robot with multifunctional modules. As shown in FIG. 1 to FIG. 8, the intelligent garden robot with multifunctional modules includes a first connection portion 5 and a traveling component 1 connected to the first connection portion 5. The traveling component 1 is configured to travel in a traveling direction under driving of a power unit.

[0043] The intelligent garden robot with multifunctional modules further includes at least one or more of a snow sweeping component 2, a mowing component 3, and a leaf blowing component 4.

[0044] The snow sweeping component 2 includes a first snow shovel 21, a first driving device 22 and a second connection portion 26. The first snow shovel 21 is movably connected to the second connection portion 26. The first driving device 22 is connected to the first snow shovel 21. The first driving device 22 is configured to drive the first snow shovel 21 to reciprocate to cut a snow layer. The first snow shovel 21 is configured to throw the cut snow layer to a collection area along a first direction. The second connection portion 26 is detachably connected to the first connection portion 5.

[0045] The mowing component 3 includes a cutting edge 31 , a second driving device and a third connection portion 32, the cutting edge 31 is movably connected to the third connection portion 32. The second driving device is connected to the cutting edge 31, and the second driving device is configured to drive the cutting edge 31 to reciprocate for mowing; the third connection portion 32 is detachably connected to the first connection portion 5.

[0046] The leaf blowing component 4 includes a fan 41 and a fourth connection portion 42. The fan 41 is connected to the fourth connection portion 42. The fan 41 has an air outlet channel 412 for performing leaf blowing operations. The fourth connection portion 42 is detachably connected to the first connection portion 5.

[0047] In this embodiment, the traveling component 1 can be moved by traveling wheels or tracks driven by a power unit. The power unit can be driven by converting energy such as electrical energy and thermal energy into mechanical energy. The controller and memory can be provided in the traveling component 1, and the traveling path and obstacle avoidance algorithm can be preset in the memory for the controller to invoke. After invoking the preset traveling path and obstacle avoidance algorithm in the memory, the controller can make the traveling component 1 automatically travel along the cleaning path by controlling the start and stop timing of the power unit. The steering operation of the traveling component 1 can be realized by the differential speed of the traveling wheels on both sides or the tracks on both sides. [0048] The first driving device 22 can include a motor and other devices for providing power and a supporting transmission mechanism (such as a reducer, a worm gear device, a crank-rocker mechanism, a cam component, etc.), to make the first snow shovel 21 reciprocate. The reciprocating motion can be circular motion, reciprocating swing, reciprocating linear motion or combinations thereof. The first snow shovel 21 can be in an arc shape, and the tail end thereof has a blade. When the above-mentioned reciprocating motion is in the stage of moving along the direction of the snow layer to be cut, the blade portion is configured to cut the snow layer accumulated in blocks under the force provided by the first driving device 22. When the above-mentioned reciprocating motion is in the stage of moving along the direction of the collection area, the first snow shovel 21 can use the arc-shaped structure to shovel a part of the cut snow layer and throw the snow to the collection area for recovery under the force provided by the first driving device 22. The collection area can be an accommodating compartment provided in the snow sweeping component 2 or the traveling component 1 , or can be a working area for secondary transfer of the part of the thrown snow. In practical applications, it is only necessary to transfer the cut snow layer to the effect that it no longer hinders the path that the intelligent garden robot with multifunctional modules has traveled, which is not limited herein.

[0049] The second driving device can include a motor and other devices for providing power and a supporting transmission mechanism (such as a reducer, a worm gear device, a crank-rocker mechanism, a cam component, etc.), to make the cutting edge 31 reciprocate. The reciprocating motion can be circular motion, reciprocating swing, reciprocating linear motion and combinations thereof. There is one cutting edge 31 or there are a plurality of spaced apart cutting edges 31. The blade portion of the cutting edge 31 can continuously cut the weeds on the sweeping path with the above-mentioned reciprocating motion.

[0050] The fan 41 is configured to blow the fallen leaves on the cleaning path (i.e., the fallen leaves in the target leaf blowing area) to other areas through wind power.

[0051] The first connection portion 5 can be fixed to the second connection portion 26, the third connection portion 32, and the fourth connection portion 42 by means of snap-connection or plug-in connection in which the protrusion cooperates with the concave cavity, and by means of other connecting devices, such as threaded fastener connection, pin connection, etc. During the actual application, the user can respectively connect different functional components (the snow sweeping component 2, the mowing component 3, and the leaf blowing component 4) to the traveling component 1 when snow sweeping, lawn mowing, and leaf blowing operations are required, and can replace the functional components on the traveling component 1 at any time. In this way, the functions of snow sweeping, mowing and leaf blowing are integrated into the intelligent garden robot with multifunctional modules, so that the intelligent garden robot with multifunctional modules can automatically perform snow sweeping, mowing and leaf blowing operations according to user needs, which replaces the traditional method of manual cleaning, improves the efficiency of courtyard cleaning, reduces labor costs, and improves the applicability of the intelligent garden robot with multifunctional modules.

[0052] It should be noted that except for the snow sweeping component 2, the mowing component 3, and the leaf blowing component 4, the intelligent garden robot with multifunctional modules can also include other functional components. Other functional components can also be detachably connected to the traveling component 1 according to user needs, to further expand the functions of the intelligent garden robot with multifunctional modules. Other functional components can refer to the snow sweeping component 2, the mowing component 3 and the leaf blowing component 4, which is detachably connected to the first connection portion 5 by means of snap-connection or plug-in connection, threaded fastener connection, pin-shaft connection in which the protrusion cooperates with the concave cavity, and can be replaced at any time as needed.

[0053] Further, as shown in FIG. 3 to FIG. 5, in an exemplary embodiment, the snow sweeping component 2 further includes a second snow shovel 23 connected to the first driving device 22. The first driving device 22 is configured to drive the second snow shovel 23 to reciprocate, to receive the snow layer thrown by the first snow shovel 21 along the first direction and throw the snow layer to a target snow throwing area along a second direction.

[0054] The first driving device 22 can be arranged in two groups. One group of the first driving devices 22 is configured to drive the first snow shovel 21, and the other group of the first driving devices 22 is configured to drive the second snow shovel 23. The first driving device 22 can include a motor and other devices for providing power and a supporting transmission mechanism (such as a reducer, a worm gear device, a crank-rocker mechanism, a cam component, etc.), to make the second snow shovel 23 reciprocate. The reciprocating motion can be circular motion, reciprocating swing, reciprocating linear motion and combinations thereof. The second snow shovel 23 can continuously transfer the snow layer thrown by the first snow shovel 21 to the target snow throwing area by means of pushing and throwing under the power provided by the first driving device 22 with the above reciprocating movement. The target snow throwing area can be located outside the intelligent garden robot with multifunctional modules. The second snow shovel 23 can perform a secondary transfer of the snow layer, which is more convenient to control the transfer path of the snow layer cut by the first snow shovel 21. [0055] Further, as shown in FIG. 3 to FIG. 5, in an exemplary embodiment, the first snow shovel 21 includes a rotating shaft 212 and a first shovel portion 211.

An axial direction of the rotating shaft 212 is perpendicular to the traveling direction. The first driving device 22 is connected to the rotating shaft 212. The first driving device 22 is configured to drive the rotating shaft 212 to rotate, to drive the first shovel portion 211 to rotate and cut the snow layer. The first shovel portion 211 is configured to throw the cut snow layer to the collection area along the first direction. The first direction is away from the traveling direction.

[0056] The first shovel portion 211 has multiple helical turns. The blade of the first shovel portion 211 is provided on a side away from the rotating shaft 212, and multiple cutting positions can be formed in the horizontal direction (i.e., the axial direction of the rotating shaft 212), to improve the cutting efficiency. The first shovel portion 211 can use the spiral structure to receive a part of the cut snow layer, and with the rotation of the rotating shaft 212, the part of the snow layer can be thrown backward (i.e., toward a direction opposite to the traveling direction) to the collection area through centrifugal action.

[0057] Further, as shown in FIG. 3 to FIG. 5, in an exemplary embodiment, the second snow shovel 23 includes a snow sweeping turntable 231 and a plurality of second shovel portions 232. The second shovel portions 232 are provided along a circumference of the snow sweeping turntable 231. The first driving device 22 is connected to the snow sweeping turntable 231. The first driving device 22 is configured to drive the snow sweeping turntable 231 to rotate, to drive the second shovel portion 232 to receive the snow layer thrown by the first shovel portion 211 along the first direction and throw the snow layer to the target snow throwing area along the second direction.

[0058] The second shovel portions 232 are spaced apart along the circumferential direction of the snow sweeping turntable 231. The second shovel portion 232 can receive the snow layer thrown by the first shovel portion 211. With the rotation of the snow sweeping turntable 231, the part of the snow layer is thrown to the target snow throwing area (which can be the exterior of the intelligent garden robot with multifunctional modules) by centrifugal action in a direction away from the center of the snow sweeping turntable 231, to realize the secondary transfer of the snow layer.

[0059] Further, as shown in FIG. 3 to FIG. 5, in an exemplary embodiment, an axial direction of the snow sweeping turntable 231 is perpendicular to the axial direction of the rotating shaft 212. The snow sweeping turntable 231 has a first end surface facing the first direction. The second shovel portion 232 is provided on the first end surface. The first driving device 22 includes a first rotary motor and a worm gear component 221. The first rotary motor is connected to the snow sweeping turntable 231. The first rotary motor is connected to a worm gear of the rotating shaft through the worm gear component 221. The first rotary motor is configured to simultaneously drive the snow sweeping turntable 231 and the rotating shaft 212 to rotate.

[0060] In this embodiment, the first driving device 22 can simultaneously drive the first snow shovel 21 and the second snow shovel 23 through a device that provides power (the first rotary motor). Therefore, the synergy between the actions of the first snow shovel 21 and the second snow shovel 23 is improved while the material cost is saved.

[0061] Further, as shown in FIG. 3 to FIG. 5, in an exemplary embodiment, the snow sweeping component 2 further includes a guide channel 24. One end of the guide channel 24 faces the second snow shovel 23, and the other end of the guide channel 24 extends along the second direction.

[0062] In this embodiment, the guide channel 24 is configured to guide the throwing direction of the snow layer after the secondary transfer by the second snow shovel 23, and the snow layer can be thrown to the target snow throwing area more accurately. The guide channel 24 can be a pipe or a baffle as shown in FIG. 3. In practical applications, it only needs to play the role of guiding the throwing direction of the snow layer through the blocking effect, which is not limited herein.

[0063] Further, as shown in FIG. 3 to FIG. 5, in an exemplary embodiment, one end of the guide channel 24 is vertical. Another end of the guide channel 24 is extending upward from a direction horizontally away from one end of the guide channel 24. The snow sweeping component 2 further includes a third driving device connected to one end of the guide channel 24. The third driving device is configured to drive another end of the guide channel 24 to rotate around one end of the guide channel 24.

[0064] In this embodiment, when the snow sweeping turntable 231 is vertical as shown in FIG. 4 and FIG. 5, the snow layer will be thrown upward by the second shovel portion 232 under the centrifugal action of the rotation of the snow sweeping turntable 231 and enter the guide channel 24 from the lower end of the guide channel 24. Since the upper end of the guide channel 24 deviates from the lower end of the guide channel 24 in the horizontal direction, the snow layer entering the guide channel 24 will be thrown out from the upper end of the guide channel 24 in a parabolic direction away from the guide channel 24 horizontally. When the third driving device drives the guide channel 24 to rotate, the upper end of the guide channel 24 can be rotated relative to the lower end of the vertical guide channel 24. Therefore, the throwing angle of the snow layer on the horizontal plane can be easily adjusted as required. The third driving device may include a rotary motor and a corresponding transmission mechanism.

[0065] It can be understood that the third driving device can be electrically connected to the controller, and the snow sweeping path and the snow sweeping strategy algorithm can be preset in the memory. When the controller calls the snow sweeping path and the snow sweeping strategy algorithm in the memory, corresponding control signals can be sent to the third driving device, to automatically adjust the snow throwing angle on the horizontal plane by controlling the rotation angle of the guide channel 24.

[0066] Further, as shown in FIG. 3 to FIG. 5, in an exemplary embodiment, the snow sweeping component 2 further includes a snow shield 25 rotatably connected to another end of the guide channel 24 along a horizontal direction. The snow sweeping component 2 further includes a fourth driving device connected to the snow shield 25. The fourth driving device is configured to drive the snow shield 25 to rotate relative to the guide channel 24, to adjust a throwing angle of the snow layer thrown from another end of the guide channel 24 in a vertical direction.

[0067] In this embodiment, when the snow layer entering the guide channel 24 is thrown from the upper end of the guide channel 24 in a parabolic direction away from the guide channel 24 horizontally, the blocking effect of the snow shield 25 can limit the throwing angle of the snow layer in the vertical direction. The snow shield 25 provided at the position shown in FIG. 3 to FIG. 5 is taken as an example. The smaller the angle between the snow shield 25 and the ground, the smaller the angle at which the snow layer is thrown from the upper end of the guide channel 24 (the angle between the tangential direction of the throwing direction and the ground). The fourth driving device drives the snow shield 25 to rotate, and the throwing angle of the snow layer in the vertical direction can be conveniently adjusted as required. The fourth driving device can include a rotary motor and a corresponding transmission mechanism.

[0068] It can be understood that the fourth driving device can be electrically connected to the controller, and the snow sweeping path and the snow sweeping strategy algorithm can be preset in the memory. When the controller calls the snow sweeping path and the snow sweeping strategy algorithm in the memory, corresponding control signals can be sent to the fourth driving device, to automatically adjust the snow throwing angle in the vertical direction by controlling the rotation angle of the snow shield 25.

[0069] Further, in an exemplary embodiment, the snow sweeping component 2 further includes a first distance sensing device (not shown) electrically connected to the first driving device 22. The first distance sensing device is configured to detect a thickness of the snow layer on a ground. The first distance sensing device is configured to send a snow sweeping signal to the first driving device 22 when the thickness of the snow layer exceeds a first thickness threshold, and the first driving device 22 is configured to drive the first snow shovel 21 to reciprocate when receiving the snow sweeping signal.

[0070] The first distance sensing device can be a photoelectric distance sensor, the first distance sensing device can be electrically connected to the first driving device 22 through the controller, and the controller can send a corresponding start signal to the first driving device 22 according to the snow sweeping signal fed back by the first distance sensing device, to automatically control the timing of the snow sweeping operation of the snow sweeping component 2. It can be understood that the first distance sensing device can also be electrically connected to the power unit, the third driving device, the fourth driving device of the traveling component 1 through the controller, the controller can automatically control the movements of the traveling component 1, the guide channel 24 and the snow shield 25 based on the detection result of the first distance sensing device, to improve the automation and intelligence of the intelligent garden robot with multifunctional modules.

[0071] Further, in an exemplary embodiment, the snow sweeping component 2 further includes a first weather sensing device (not shown) electrically connected to the first driving device 22. The first weather sensing device is configured to obtain a weather condition. The first weather sensing device is configured to send a snow sweeping signal to the first driving device 22 when the weather condition meets a first preset condition, and the first driving device 22 is configured to drive the first snow shovel 21 to reciprocate when receiving the snow sweeping signal.

[0072] In this embodiment, the first preset condition can include various indicators representing snowfall through different dimensions. For example, whether the duration of snowfall exceeds the preset time threshold, whether the number of times the duration of snowfall exceeds the preset time threshold exceeds the preset number of times within a preset time period, the probability of snowfall in a preset time period in the future, or the like. In this way, the intelligent garden robot with multifunctional modules can autonomously carry out snow sweeping operations in advance according to weather conditions, avoiding the inconvenience of snow sweeping operations when the snow layer is too thick.

[0073] Further, as shown in FIG. 6, in an exemplary embodiment, the mowing component 3 further includes a mowing turntable 33 rotatably connected to the third connection portion 32.

The second driving device is configured to drive the mowing turntable 33 to rotate, to drive the cutting edge 31 for mowing.

[0074] In this embodiment, a plurality of cutting edges 31 can be provided along the circumferential direction of the mowing turntable 33, the mowing turntable 33 is driven to rotate by the second driving device, to improve the mowing efficiency. The second driving device can include a rotary motor and a corresponding transmission mechanism.

[0075] Further, as shown in FIG. 6, in an exemplary embodiment, there are two spaced apart mowing turntables 33.

[0076] When there are two mowing turntables 33 as shown in the figure, the mowing efficiency can be further improved.

[0077] Further, in an exemplary embodiment, the mowing component 3 further includes a second distance sensing device (not shown) electrically connected to the second driving device.

[0078] The second distance sensing device can be a photoelectric distance sensor, and the second distance sensing device can be electrically connected to the second driving device through the controller. The controller can send a corresponding start signal to the second driving device according to the mowing signal fed back by the second distance sensing device, to automatically control the timing of the mowing component 3 for mowing. It can be understood that the second distance sensing device can also be electrically connected to the power unit of the traveling component 1 through the controller, and the controller can automatically control the traveling action of the traveling component 1 based on the detection result of the second distance sensing device, to improve the automation and intelligence of the intelligent garden robot with multifunctional modules.

[0079] Further, in an exemplary embodiment, the mowing component 3 further includes a recording module (not shown) for storing a preset growth period, and the recording module is electrically connected to the second driving device.
