[0002] With the increasing popularity of electric two-wheeled vehicles (such as electric scooters and electric bicycles), the demand for convenient and efficient charging methods is growing. Traditional wired charging methods are not only cumbersome and inconvenient to use, but also prone to poor contact or environmental factors affecting charging performance. Wireless charging technology, due to its contactless nature, is gradually becoming an effective solution to these problems, enabling a convenient and fast charging experience. However, current wireless charging systems still face challenges in alignment accuracy, charging stability, and management, requiring further improvement and innovation. Summary of the Invention
[0003] The purpose of this invention is to provide a wireless charging device for two-wheeled vehicles to overcome the problems of insufficient alignment accuracy, poor charging stability and inconvenient operation in the prior art.
[0004] To achieve the above objectives, this utility model provides a wireless charging device for a two-wheeled vehicle. The wireless charging device includes a charging base, a transmitting module, and a receiving module. The charging base has a track structure with at least one positioning groove to restrain the front or rear wheels of the two-wheeled vehicle, allowing the vehicle to stop at a preset position. The transmitting module is disposed in one of the alignment areas of the charging base. The receiving module is disposed on one side of the two-wheeled vehicle. When the two-wheeled vehicle is stopped at the preset position, the receiving module aligns with the transmitting module to perform wireless charging.
[0005] In one embodiment of the present invention, the above-mentioned track structure is provided with a stop member, which is disposed on the entry direction side of the at least one positioning groove. One end of the stop member is connected to the bottom surface of the track structure, and the other end has a height difference relative to the track structure to form an inclined surface extending from low to high along the entry direction of the two-wheeled vehicle.
[0006] In one embodiment of the present invention, the entrance end of the above-mentioned track structure is provided with a pair of guide plates, which are arranged opposite to each other on opposite sides of the entrance end of the track structure to form a convergent guide channel to assist a two-wheeled vehicle in entering the track structure.
[0007] In one embodiment of the present invention, the above-mentioned transmitting module includes a transmitting coil and the receiving module includes a receiving coil. When the receiving module enters the alignment area defined by the X-axis, Y-axis and Z-axis, it can receive power through magnetic resonance coupling and supply it to the two-wheeled vehicle.
[0008] In one embodiment of this utility model, the alignment region is a three-dimensional spatial range, with an allowable offset distance of 5 to 10 mm in the X-axis and Y-axis directions and an allowable offset distance of 10 to 15 mm in the Z-axis direction.

[0019] To make the above and other objects, features, and advantages of this utility model more apparent and understandable, preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Furthermore, the directional terms used in this utility model, such as up, down, top, bottom, front, back, left, right, inside, outside, side, surrounding, center, horizontal, transverse, vertical, longitudinal, axial, radial, uppermost, or lowermost, are merely for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting it.
[0020] Please also refer to Figures 1 to 4 As shown, this utility model mainly provides a wireless charging device for two-wheeled vehicles. The wireless charging device 1 is used to charge, for example, scooters or other types of two-wheeled vehicles 2, without contact, and can achieve the convenient operation characteristics of automatic charging when parked and no need for human supervision.
[0021] Specifically, the wireless charging device 1 mainly includes a charging base 11 that can be installed on the ground, a transmitting module 12, and a receiving module 13. The charging base 11 has a track structure 111, in which at least one positioning groove 111a is provided for guiding the two-wheeled vehicle 2 to slide in and position it in a preset position. When the two-wheeled vehicle 2 is parked in the preset position, the support frame 21 under its vehicle body is in a retracted state and is supported by the track structure 111 of the charging base 11. The transmitting module 12 is disposed in the alignment area of the charging base 11, and the receiving module 13 is disposed on one side of the two-wheeled vehicle 2. When the two-wheeled vehicle 2 enters the charging base 11 in a predetermined direction and stops in the preset position, the receiving module 13 can be accurately aligned with the transmitting module 12, thereby realizing wireless charging.
[0022] In some embodiments, the receiving module 13 may be positioned at different locations such as the side, front, and rear ends of the two-wheeled vehicle 2, depending on the size or structural differences of the vehicle, to adapt to different brands or types of two-wheeled vehicles. The transmitting module 12 may be configured accordingly based on the position of the receiving module 13 to ensure effective alignment and charging efficiency between the two.
[0023] like Figure 2 and Figure 3As shown, the charging base 11 is provided with a track structure 111 into which the two-wheeled vehicle 2 slides. The track structure 111 has at least one positioning groove 111a to restrict the front wheels of the two-wheeled vehicle 2 to a preset position. When the two-wheeled vehicle 2 enters the track structure 111 and its wheels fall into the positioning groove 111a, accurate alignment of the receiving module 13 and the transmitting module 12 is ensured. In some embodiments, the positioning groove 111a may be located at the position corresponding to the rear wheel of the two-wheeled vehicle 2 to restrict the rear wheel; or in other embodiments, two positioning grooves may be provided simultaneously, corresponding to the front wheel and the rear wheel respectively.
[0024] To improve the positioning reliability of the two-wheeled vehicle 2, a stop 111b is provided in the track structure 111. The stop 111b is located on one side of the sliding direction of the positioning groove 111a and has an inclined structure. One end of the stop 111b is connected to the bottom surface of the track structure 111 and extends from low to high along the sliding direction of the two-wheeled vehicle 2, so that the other end has a height difference relative to the track structure 111. Therefore, when the two-wheeled vehicle 2 slides into the track structure 111, its front wheels can climb up and pass through the stop 111b and enter the positioning groove 111a. When exiting in the reverse direction, the height difference formed by the stop 111b can have a blocking effect, preventing the two-wheeled vehicle 2 from accidentally sliding out of the track structure 111 without the application of external force.
[0025] In addition, a pair of guide plates 111c are provided at the entrance end of the track structure 111. The guide plates 111c are respectively disposed on opposite sides of the entrance end of the track structure 111 and are arranged opposite each other to form a guide channel that narrows from the outside to the inside. With this arrangement, when the two-wheeled vehicle 2 approaches the track structure 111 of the charging station 11, the guide plates 111c can help correct its entry direction and guide it to slide into the track structure 111, improving the smoothness of parking.
[0026] Please refer to Figure 2 and Figure 4 In one embodiment, the transmitting module 12 includes a transmitting coil 121, an indicator light group 122, and an electromagnetic lock device 123. The transmitting module 12 is controlled by a microcontroller module 14 located inside the charging base 11, which controls, for example, the charging start / stop of the transmitting coil 121, the status display of the indicator light group 122, and the control of the electromagnetic lock device 123. The power required by the transmitting module 12 is provided by a power conversion module 15 located inside the charging base 11. The receiving module 13 is located on one side of the two-wheeled vehicle 2 and includes a receiving coil 131 and a circuit board 132. The circuit board 132 is used to receive, rectify, and regulate electrical energy before outputting it to the battery module of the two-wheeled vehicle 2 for charging.
[0027] When the receiving module 13 enters the alignment area corresponding to the transmitting module 12, it enters the effective power coupling space for magnetic resonance wireless charging. The alignment area refers to a three-dimensional spatial range defined outward from the transmitting surface of the transmitting coil 121. This is the effective charging space where stable energy coupling can be achieved between the transmitting and receiving modules, allowing for a certain degree of positional deviation. Specifically, the X and Y axes have a permissible offset tolerance distance (e.g., approximately 5 to 10 mm), while the Z-axis (vertical direction) has a permissible offset tolerance distance (e.g., approximately 10 to 15 mm). When the receiving module 13 is located within the alignment area, power transmission can be achieved through magnetic resonance coupling. After rectification and voltage regulation within the receiving module 13, electrical energy can be stably output to power the battery module of the two-wheeled vehicle 2. Compared to traditional electromagnetic induction charging technology, magnetic resonance coupling allows for larger alignment errors, which helps improve usability and parking tolerance.
[0028] In this embodiment, the indicator light group 122 can be disposed on the upper surface area of the housing of the transmitting module 12 and controlled by the microcontroller module 14 inside the charging dock 11. The indicator light group 122 can automatically switch the corresponding light signal according to the operating status of the wireless charging device 1, so that the on-site user or maintenance personnel can identify the device status in real time. Specifically, the light signal modes are as follows: a constant blue light indicates that the device is in working mode (i.e., wireless charging is in progress), a flashing blue light indicates that the device is in standby mode, a flashing red light indicates an abnormal state (requiring inspection or maintenance), and a lit green light indicates that the device is powered on.
[0029] In this embodiment, the electromagnetic lock device 123 is positioned near the junction of the transmitting module 12 and the receiving module 13. When the receiving module 13 aligns with the transmitting module 12, the electromagnetic lock device 123 performs a locking operation to fix the receiving module 13 in the aligned state. Figure 4 As shown, the electromagnetic lock device 123 includes a movable locking pin 123a, which can be inserted into a corresponding lock hole 130 on the housing of the receiving module 13 to achieve a locking effect.
[0030] In this embodiment, the locking action is automatically triggered by a mechanical structure. The locking pin 123a is triangular in shape. When the receiving module 13 slides and aligns with the transmitting module 12, the housing of the receiving module 13 is guided by the inclined surface of the locking pin 123a, pressing the locking pin 123a in. After the two are fully aligned, the locking pin 123a automatically pops out under the action of internal elasticity and inserts into the lock hole 130, completing the mechanism locking. The unlocking operation is controlled by the microcontroller module 14 inside the charging base 11. When the microcontroller module 14 receives the unlocking command, it controls the electromagnetic lock device 123 to be energized, driving the locking pin 123a to retract, releasing the locked state, and allowing the two-wheeled vehicle 2 to detach from the charging base 11. When the receiving module 13 and the transmitting module 12 are separated, the microcontroller module 14 will immediately control the electromagnetic lock device 123 to be de-energized to prevent the electromagnetic lock device 123 from overheating and ensure the safety and stability of the system.
[0031] In some applications, the microcontroller module 14 can communicate with external devices or payment systems to receive unlocking commands triggered by user operations, thereby controlling the electromagnetic lock device 123 to unlock. For example, the unlocking command may be generated by the user pressing a physical button on the charging dock 11 or by wireless communication (such as Bluetooth or Wi-Fi) via a paired mobile device, or it may be automatically triggered after payment is completed via a mobile device, or it may be triggered manually through on-site terminal equipment (such as a self-service rental machine).
[0032] In other embodiments, the locking action can also employ an active electromagnetic lock structure controlled by the microcontroller module 14: after alignment is completed, the microcontroller sends a signal to drive the locking pin 123a to extend and lock. This allows for flexible selection of different locking modes depending on the application scenario.
[0033] As described above, the wireless charging device provided by this utility model features a track guidance and positioning structure, effectively guiding the two-wheeled vehicle to precise alignment and ensuring the optimal charging position between the transmitting and receiving modules, thereby improving charging efficiency and stability. Furthermore, an electromagnetic lock device automatically locks the receiving module, enhancing the structural stability and safety during the charging process. The overall design supports unattended and automated operation, making it suitable for shared rental and private use scenarios, significantly improving user experience and management efficiency.
[0034] Although the present invention has been disclosed with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
