TECHNICAL FIELD

[0001] Various aspects of this disclosure generally relate to wireless communication, and more particularly, to an antenna design for scooter.

BACKGROUND

[0002] The Internet of things (IoT) is the network of devices such as vehicles and home appliances that contain electronics, software, actuators, and connectivity which allows these things to connect, interact and exchange data. The IoT involves extending Internet connectivity beyond standard devices, such as desktops, laptops, smartphones and tablets, to any range of traditionally non-intemet-enabled physical devices and everyday objects. Embedded with technology, these devices can communicate and interact over the Internet, and they can be remotely monitored and controlled.

[0003] Mobile device sharing is a transportation innovation that is growing rapidly across cities. It solves the “last mile” problem by providing users an alternative device at better estimated time of arrival (ETA) and price than cars in crowded cities, reduces carbon emission, and provides a smarter transportation network to cities around the world. The future of urban mobility is shared, seamless, smart and environmentally sustainable. Motorized scooters (also may be referred to as e-scooter) would be a good addition to the active mobility landscape, serving unmet demands in the first-mile-last- mile (FMLM) travel segment.

[0004] Traditional e-scooter sharing IoT solution has limitations on the IoT capabilities. For example, traditional Global Positioning System (GPS) antenna design is not suited for e-scooter IoT component. Comparing with bike, the e-scooter is a much smaller device. As a result, many e-scooters can be seen falling on the ground or against the wall at all angles in a very limited space. This causes major challenge to the traditional GPS Antenna’s vertical or horizontal design. The GPS signal receiving performance is not good enough to meet regulatory requirements on device tracking or to satisfy an optimal user experience in locating the scooters. SUMMARY

[0005] The following presents a simplified summary in order to provide a basic understanding of various aspects of the disclosed invention. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. The sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

[0006] In one aspect of the disclosure, a scooter is provided. The scooter may include a steering column. The scooter may include a rider-support-platform coupled to the steering column. The scooter may include an antenna attached to the steering column. The antenna may be configured to perform wireless communication. The antenna may have a first inclination angle relative to the steering column.

[0007] In another aspect of the disclosure, a method of providing a scooter is provided. The method may include providing a steering column of the scooter. The method may include coupling a rider-support-platform to the steering column. The method may include attaching an antenna to the steering column. The antenna may be configured to perform wireless communication. The antenna may have a first inclination angle relative to the steering column.

[0008] In some embodiments, the scooter may be a motorized scooter. In some embodiments, the steering column may have a second inclination angle relative to the upper surface of the rider-support-platform. In some embodiments, the antenna may have a third inclination angle relative to the upper surface of the rider-support-platform when the scooter is being used. In some embodiments, the upper surface of the rider-support- platform may be substantially parallel to the horizontal plane when the scooter is being used. In some embodiments, the second inclination angle may be equal to the sum of the first inclination angle and the third inclination angle. In some embodiments, the third inclination angle may be in the range of 45 degrees to 60 degrees. In some embodiments, the antenna may have a fourth inclination angle relative to the horizontal plane when the scooter is placed (e.g., laid down) on the ground. In some embodiments, the fourth inclination angle may substantially equal to the first inclination angle. In some embodiments, the thickness of the antenna may be greater than a threshold. [0009] To the accomplishment of the foregoing and related ends, the aspects disclosed include the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail illustrate certain features of the aspects ofthe disclosure. These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed, and this description is intended to include all such aspects and their equivalents.

DETAILED DESCRIPTION

[0015] The detailed description set forth below in connection with the appended drawings is intended as a description of various possible configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

[0016] Several aspects of an antenna design for scooter will now be presented with reference to various apparatus and methods. The apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. [0017] FIG. 1 is a diagram illustrating an example of a scooter 100. According to various embodiments, the scooter 100 may include a main body 110 including a rider- support-platform 106 and a steering column 104 coupled to the rider-support-platform 106. According to various embodiments, the rider-support-platform 106 may be configured to support a rider directly standing on top of the rider-support-platform 106. For example, the rider-support-platform 106 may be a deck of an electric kick scooter configured for a rider to stand on. According to various embodiments, the rider-support-platform 106 may be configured to support a rider via a seat structure on the rider-support-platform 106 on which the rider may be seated. According to various embodiments, the rider-support-platform 106 may be aligned horizontally with respect to the ground. According to various embodiments, the steering column 104 may be extending in upward directions with respect to the rider- support-platform 106. According to various embodiments, the steering column 104 may be substantially vertical or upright with respect to the rider-support-platform 106. According to various embodiments, the steering column 104 may be configured for the rider to steer the direction of movement of the scooter 100. According to various embodiments, the steering column 104 may be pivotably coupled to the rider-support-platform 106. According to various embodiments, the steering column 104 may include a handle that the rider may hold onto.

[0018] In some embodiments, the scooter 100 may be a motorized scooter equipped with an IoT communication module 102, which may be an external box attached to the steering column 104. The IoT communication module 102 may enable optimization of the operations or maintenance of the motorized scooter so that efficiency may be achieved. For example, the motorized scooter may be unlocked/locked by scanning the Quick Response (QR) code. The unlock time may be less than 5 seconds, and the success rate may be higher than 90%. In some embodiments, user riding data (e.g., when you ride, where you are riding, how long you ride, etc.) may be collected in real-time. In some embodiments, the real-time data of the motorized scooter (e.g., the speed, the power volume, how far has already ride, falling down on the ground or not, etc.) may be collected. In some embodiments, customized human-machine interface (e.g., unlock or lock reminder, alarm, etc.) may be provided to users.

[0019] In some embodiments, the IoT communication module 102 may serve to track the scooters’ service status and location at any given time. The IoT communication module 102 also makes it possible to transmit commands to the scooters via cloud server. In addition, the IoT communication module 102 may contain an internal speaker for unlocking/locking indication and alerting the sensors for any abnormal activities detected (e.g., falling down, abnormal movement, etc.) to enhance operational efficiency.

[0020] In some embodiments, the design of the antenna of the IoT communication module 102 may be optimized for sharing scenario. In some embodiments, the electronics of the scooter 100 may be fail safe for electric failure and battery safety. The design of the scooter 100 may be focused on optimizing for user experience (e.g., unlock, lock) so user spends as little time interacting with the app as possible. The product may be designed specifically for situations of theft and sabotage, which is known issues in the shared device industry.

[0021] According to various embodiments, the scooter 100 may include a wheel arrangement supporting the main body 110. The wheel arrangement may include at least one front wheel 124 and at least one rear wheel 122. According to various embodiments, the wheel arrangement may be supporting the main body 110 in a manner such that the main body 110 is elevated above the ground. Accordingly, only the at least one front wheel 124 and the at least one rear wheel 122 may be in contact with the ground. Hence, the scooter 100 may be moved with respect to the ground via the rotation or turning of the at least one front wheel 124 and the at least one rear wheel 122. According to various embodiments, the at least one front wheel 124 may be configured to be steerable by the steering column 104. According to various embodiments, the at least one front wheel 124 may be coupled to the steering column 104. According to various embodiments, the steering column 104 may include a front wheel fork which holds the at least one front wheel 124.

[0022] FIG. 2 is a diagram 200 illustrating a cross-sectional view of an example of antenna design for scooter. In the example, an IoT communication module 206 may be attached to a steering column 204 of a scooter. In some embodiments, the IoT communication module 206 may be the IoT communication module 102 described above with reference to FIG. 1. In some embodiments, the steering column 204 may be the steering column 104 described above with reference to FIG. 1. In some embodiments, the steering column 204 may have an inclination angle a relative to a vertical axis when the scooter is being used (e.g., when rider is riding on the scooter). The steering column 204 may have an inclination angle d relative to the rider-support-platform of the scooter. The inclination angles a and d may be complementary angles, i.e., they add up to 90°. In some embodiments, the rider-support-platform may be substantially parallel to the ground or substantially parallel to the horizontal plane.

[0023] In some embodiments, the steering column 204 may be substantially vertical or upright with respect to the rider-support-platform. Thus, the inclination angle a may be small and the inclination angle d may be close to 90°.

[0024] The IoT communication module 206 may include an antenna 208. The antenna 208 may be enclosed within a protective cover 210 of the IoT communication module 206. In some embodiments, the antenna 208 may be affixed in the IoT communication module 206 so that the antenna 208 has an inclination angle b relative to the steering column 204. [0025] In some embodiments, the antenna 208 may have an inclination angle g relative to the ground in front of the front wheel of the scooter when the scooter is being used (e.g., when rider is riding on the scooter). The antenna 208 may also have an inclination angle e relative to the rider-support-platform of the scooter when the scooter is being used (e.g., when rider is riding on the scooter). The inclination angles g and e may be supplementary angles, i.e., they add up to 180°.

[0026] In some embodiments, the inclination angles a, b, e may be complementary angels. In some embodiments, the sum of inclination angles a and b may equal to inclination angle g minus 90°. In some embodiments, the sum of inclination angles b and e may equal to inclination angle d.

[0027] In some embodiments, the inclination angle g may be in the range of 120° to 135°. Accordingly, the inclination angle e may be in the range of 45° to 60°.

[0028] In some embodiments, the antenna 208 may have a thickness of d. The thickness of the antenna 208 may be increased to enhance the performance of the antenna 208. In some embodiments, the thickness of the antenna 208 may exceed a predetermined threshold (e.g., 2 mm, 3 mm, or 5 mm). Because of the antenna design, no matter which angle the scooter lays down on the ground or against on the wall, the IoT communication module may receive a good signal.
