BACKGROUND

[0003] The object of the present application is a mouse, comprising: a shell and switches installed in the shell, the shell being equipped with two key panels which are commonly known as the left mouse button and the right mouse button.

[0004] However, an improper clearance may be generated between the pressed part of the key panel and the button of the switch in the prior mouses due to manufacturing tolerance. Therefore, when a user presses a key panel, an extra slow-moving distance actually exists because the key panel is not accurately pressed onto the button of the switch due to tolerance so that the key panel touches the button before the button is pressed down, resulting in a feel of not giving a quick and neat press and a fuzzy feedback strength, especially a more obvious fuzzy feel during quick continuous click, thus requiring an improvement.

PARTICULAR EMBODIMENTS

[0024] The present utility model will be further described by referring to the accompanying drawings and particular embodiments so that those skilled in the art can understand and implement the present utility model better, but the listed embodiments should not be used as limitations on the present utility model.

[0025] The present application provides a mouse device capable of eliminating an improper clearance, which is used to eliminate an improper clearance (not shown in the figures). A first embodiment is shown in Figs. 1-4. A second embodiment is shown in Figs. 5-6.

[0026] As shown in Figs. 1-4, the first embodiment of a mouse device capable of eliminating an improper clearance (hereinafter referred to as "mouse device") of the present application comprises: a shell (the component symbol not indicated), a frame 3a, a plurality of springs 4 and a circuit board 5.

[0027] The shell includes a base 1 and a top shell structure 2a which are integrated with each other by assembling. The top shell structure 2a includes a cover 21 and a key panel assembly 22. The cover 21 and the base 1 are integrated with each other by assembling; the cover 21 has an opening 211, and the key panel assembly 22 is disposed on the cover 21, corresponding to the opening 211, and has a plurality of (at least two) side-by-side key panels 221.

[0028] A cylinder 26 is protruded from the internal surface of the key panels 221. As shown in Fig. 4, an end 261 of the cylinder 26 has a pressing face 2611 and a stop face 2612 opposite to each other. Preferably, a receiving space 263 is provided on one side of the cylinder 26 and the stop face 2612 is exposed in the receiving space 263. Specifically, the stop face 2612 is formed by providing the receiving space 263 in the cylinder 26 and the pressing face 2611 is opposite to the stop face 2612.

[0029]The circuit board 5 is fixed in the shell. As shown in Figs. 3 and 4, the circuit board 5 is specifically fixed to the base 1 and equipped with a plurality of switches 51. As shown in Fig. 4, a button 511 is disposed on the top surface of the switch 51.

[0030] The frame 3a is fixed in the shell. As shown in Figs. 3 and 4, the frame 3a is specifically erected and fixed to the base 1 or to the base 1 and the circuit board 5, and the frame 3a is supported between the cover 21 and the base 1 to improve the structural strength of the shell. [0031] Each of the springs 4 is respectively fixed to two corresponding points of the frame 3a, corresponding to the position of each of the cylinders 26 (the component symbol not indicated), and is springily pressed against the stop face 2612 of each of the cylinders 26.

[0032] As shown in Fig. 4, even though an improper clearance exists between the pressing face 2611 of each of the cylinders 26 and the button 511 of each of the switches 51 due to tolerance (not shown in the figure), each of the cylinders 26 is pulled down in the direction of the switches 51 together with each of the panels 211 via springy pressing of each of the springs 4 against each of the stop faces 2612 to eliminate each of the improper clearances and even noise generated during a shake or vibration.

[0033]As shown in Figs. 1, 3 and 4, one end of the springs 4 is fixed to the corresponding points of the frame 3a by various feasible methods (e.g., locking or hot melting method), and the other end of the spring 4 is bent to form an arc bending section 41 which goes into the receiving space 263 of the cylinder 26. The arc bending section 41 which goes into the receiving space 263 is springily pressed against the stop faces 2612 in the direction of the switch 51. Preferably, each of the springs 4 has a straight section (the component symbol not indicated), the arc bending section 41 and a curved part 42 between the straight section and the arc bending section 41. In addition, as shown in Fig. 4, there is a gap between the bottom edge of the arc bending section 41 and the straight section (the component symbol not indicated) so that each of the springs 4 is particularly elastic when the arc bending section 41 is springily pressed against the stop face 2612 of each of the cylinders 26.

[0034] A plurality of protruding arms 31a are protruded from the frame 3a and each of the protruding arms 31a has an allowable deformation space 311a at one end. The one end of each of the springs 4 is respectively fixed to the bottom surface of each of the protruding arms 31a, and the arc bending section 41 of each of the springs 4 respectively goes into each of the allowable deformation spaces 311a so that each of the allowable deformation spaces 311a respectively allows elastic deformation of each of the arc bending sections 41 when the arc bending section 41 is deformed due to an external force.

[0035] It is important to note that only the arc bending section 41 of each of the springs 4 respectively goes into the space 263 of each of the cylinders 26 (not shown in the figure), as mentioned above. Of course, each of the protruding arms 31 can also go into each of the receiving spaces 263 together with each of the arc bending sections 41 to achieve the benefit of protecting the arc bending section 41 at the time of assembly, as shown in Fig. 4.

[0036] Other benefits provided by the present application: The present application has the benefit of easy assembly because of the assembly method in which the springs 4 are fixed to the bottom surface of the protruding arms 31a of the frame 3a by a locking or hot melting method without any complex structure or special assembly. The present application has the benefits of low manufacturing cost and simple (uncomplicated) structure because the improper clearance can be eliminated at only a cost of simple springs 4. Because the spring 4 has an arc bending section 41 and there is the above-mentioned gap between the bottom edge of the arc bending section 41 and the straight section, a proper pressing elastic force can be provided to eliminate the improper clearance. Because the spring 4has an arc bending section 41, the present application has the benefit of avoiding damages to the springs 4 by the cylinders 26 during assembly of the key panels 221. If the pressing elastic force of the springs 4 needs to be adjusted, just adjust the above-mentioned gap between the bottom edge of the arc bending section 41 and the straight section. Therefore, the present application has the benefit of easy adjustment to the pressing elastic force. Because the protruding arm 31a has an allowable deformation space 311a, even if the arc bending section 41 is deformed by accident due to external forces during assembly, these deformations of the arc bending section 41 will occur only in the allowable deformation space 311a so that the arc bending section 41 is not damaged due to blockage during deformation.

[0037] As shown in Figs. 5 and 6, the second embodiment of the mouse device of the present application is roughly the same as the first embodiment. The only difference is that the top shell structure 2b and the frame 3b are different from those of the first embodiment, as mentioned below.

[0038] The top shell structure 2b includes a hood 23 which has a plurality of key panels 231 or integrally connected key panels 231. The hood 23 and the base 1 are integrated with each other by assembling. [0039] The frame 3b is an upwardly arched frame and has a plurality of protruding arms 31b, each of which has an allowable deformation space 311b. The periphery of the frame 3b and the periphery of the base 1 are fixed to each other, and the upwardly arched part of the frame 3b snugly fits the internal surface of the hood 23 (except each of the key panels 231) so that the frame 3b is supported between the interface surface of the hood 23 and the periphery of the base 1 to improve the structural strength of the shell. In addition, a plurality of (more than three) hollowed-out holes 32 are spread all over the frame 3b for reducing the weight, as shown in Fig. 6.

[0040] The above-mentioned embodiments are preferred embodiments only which fully describe the present utility model, and the protection scope of the present utility model is not limited to them. Any equivalent substitutions or changes made by those skilled in the art on the basis of the present utility model shall fall within the protection scope of the present utility model. The protection scope of the present utility model is subject to the claims.
