In recent years, wireless charging technology has received widespread attention in the electric vehicle field due to its advantages of being plug-and-play-free and highly safe. However, existing wireless charging solutions for two-wheeled electric vehicles still face significant technical bottlenecks.

[0003] Currently, most mainstream wireless charging devices on the market adopt a split design, meaning the induction coil of the charging receiver is separate from the receiver box. The coil is integrated into the kickstand structure, while the receiver box needs to be built into the vehicle body. This design requires users to make structural modifications to the vehicle during installation, making the operation complicated. Furthermore, the existing kickstands are not height-adjustable, making it difficult to be compatible with the different chassis heights of different vehicle models. Utility Model Content

[0038] One embodiment of this utility model provides a wireless charging footrest for electric vehicles, see reference. Figures 1 to 6 ,include:

[0039] Support base 1, wherein a charging circuit board is provided inside the support base 1;

[0040] A charging base 2 is movably connected to the support base 1. A charging coil is provided inside the charging base 2, and the charging coil is electrically connected to the charging circuit board through a connecting line.

[0041] The lifting assembly 3 is rotatably connected to the support base 1. The lifting assembly 3 is used to adjust the length of the foot support. The lifting assembly 3 includes a first lifting part 31 and a second lifting part 32. The first lifting part 31 is used to connect with the electric vehicle. The bottom of the second lifting part 32 is provided with a connector 6. The connector 6 is rotatably connected to the charging base 2.

[0042] This invention solves the problems of cumbersome installation and inability to adjust the height of the kickstand in existing wireless charging systems for electric vehicles. By integrating the charging coil, charging circuit board, and kickstand into a single unit, the step of embedding the receiver box into the vehicle body, as in separate structures, is eliminated. Users can directly connect to an external power source via the kickstand's plug 5 to achieve wireless charging without structural modifications to the vehicle, simplifying the charging process. Furthermore, the lifting component 3 on the support base 1 allows for height adjustment of the kickstand, thus ensuring compatibility with different vehicle chassis heights. In this embodiment, the support base 1 is a hollow structure with a charging circuit board embedded inside. This circuit board converts the electrical energy provided by the external power source into a wireless charging signal. The wireless charging signal is transmitted to the battery of the electric vehicle through the plug 5, thereby realizing wireless charging. The lifting assembly 3 includes a first lifting part 31 and a second lifting part 32. The first lifting part 31 is located above the support base 1 and has a connecting part 313 for connecting to the electric vehicle. The other end of the first lifting part 31 is threaded to the support base 1 for adjusting the length of the foot support. One end of the second lifting part 32 is threaded to the support base 1 to further adjust the length of the foot support, and the other end has a connector 6. The charging base 2 is movably connected to the connector 6 and can be adjusted relative to the support base 1 by rotation or other means. The charging base 2 contains a charging coil, which is electrically connected to the charging circuit board through a connecting line. When the charging base 2 is aligned with the external wireless charging transmitter, the charging coil can receive the wireless charging signal emitted by the transmitter and transmit the signal to the charging circuit board through the connecting line, thereby realizing the transmission of electrical energy and the function of wireless charging.

[0043] Furthermore, the charging base 2 is provided with a connecting part 313 and a fixing seat 7 fixed to the connecting part 313. The connecting part 313 and the fixing seat 7 each have an enclosing groove, and the two enclosing grooves are connected to form a receiving groove 21. The connector 6 is embedded in the receiving groove 21. Specifically, the two side walls of the connecting part 313 extend inward to form a first enclosing groove, and the two side walls of the fixing seat 7 extend inward to form a second enclosing groove. When the connecting part 313 and the fixing seat 7 are locked with screws, the first enclosing groove and the second enclosing groove are engaged to form a spherical receiving groove 21. The connector 6 has a spherical structure with a diameter slightly smaller than the inner diameter of the receiving groove 21, so that the connector 6 can rotate 360° within the receiving groove 21. The rotational damping of the connector 6 can be controlled by adjusting the tightness of the screws to adapt to the angle adjustment requirements of the charging base 2 for different ground inclinations. In addition, the tightness of the screws can also accommodate connectors 6 of different diameters.

[0044] In actual installation, users only need to insert the connector 6 into the receiving groove 21, align the screw holes of the connector 313 and the fixing seat 7, and tighten the screws to complete the assembly. When it is necessary to repair or replace the base, the connector 313 and the fixing seat 7 can be quickly separated by removing the screws. It is simple and quick and reduces maintenance costs.

[0045] Furthermore, the charging base 2 has a wiring connection hole 22, and the connector 6 has a connection through hole 61. The charging coil (not shown) is electrically connected to the charging circuit board through the wiring connection hole 22 and the connection through hole 61. The arrangement of the connection through hole 61 and the wiring connection hole 22 ensures that the wiring is neatly and securely connected to the charging circuit board (not shown), avoiding wear and tear on exposed wiring and interference from the external environment. In this embodiment, the wiring of the charging coil passes through the wiring connection hole 22 and the connection through hole 61 to electrically connect to the charging circuit board, realizing the transmission of electrical energy and signals between the charging coil and the charging circuit board. The connection between the wiring of the charging coil and the charging circuit board can be achieved by soldering, plugging, or other electrical connection methods.

[0046] Furthermore, the support base 1 is provided with an external thread 11, and the first lifting part 31 and the second lifting part 32 are provided with internal threads 311. The first lifting part 31 and the second lifting part 32 are respectively threadedly connected to the support base 1. Specifically, the support base 1 is a hollow cylindrical structure with an external thread 11 on its outer surface. The first lifting part 31 and the second lifting part 32 are respectively designed as tubular structures with internal threads 311 matching the external thread 11 on their inner walls. By rotating the first lifting part 31 and the second lifting part 32, the first lifting part 31 and the second lifting part 32 can be moved axially along the support base 1, thereby adjusting the overall length of the foot support.

[0047] Furthermore, the support base 1 is provided with multiple fixing holes 12, and the first lifting part 31 and the second lifting part 32 are fixedly connected to the support base 1 by screws passing through the fixing holes 12. Specifically, the support base 1 is provided with multiple fixing holes 12 along the axial direction. The fixing holes 12 are oblong holes. The oblong hole design allows the screw to have a certain adjustment space in its length direction, so that the rotation position of the first lifting part 31 or the second lifting part 32 is not restricted and can be freely rotated to any position. Compared with the position restriction of the traditional round hole, the oblong hole design is not subject to the position restriction of the round hole, so that the first lifting part 31 and the second lifting part 32 can rotate to any position when rotating in the circumferential direction. The screw can always form an alignment channel with the oblong hole, so that the first lifting part 31 and the second lifting part 32 can be fixed in the current target position.

[0048] Specifically, when the user needs to adjust the length of the foot support, the user first removes the screws and then manually rotates the first lifting part 31 or the second lifting part 32. Due to the meshing of the threads, the first lifting part 31 and the second lifting part 32 will move up and down along the axis of the support base 1. For example, when it is necessary to extend the length of the foot support, the first lifting part 31 can be rotated to move upward along the support base 1, thereby extending the length of the foot support. When the first lifting part 31 rises to the top end of the support base 1, if it is still necessary to further extend the foot support, the second lifting part 32 can be rotated to move downward along the support base 1, thereby further extending the length of the foot support. At this time, the bidirectional extension of the first lifting part 31 and the second lifting part 32 can significantly improve the adjustment range. When the first lifting part 31 or the second lifting part 32 is adjusted to the target position, the screw is reinserted into the screw hole 312 of the first lifting part 31 or the second lifting part 32 and aligned with the fixing hole 12 of the support base 1. The screw is then tightened to lock the position of the lifting part and prevent the lifting part from shifting.

[0049] Furthermore, the wireless charging stand also includes a plug 5. One end of the plug 5 passes through the support base 1 and is electrically connected to the charging circuit board, while the other end is electrically connected to an external power source. In this embodiment, the plug 5 is used to transmit electrical energy. Through the plug 5, the charging circuit board can receive power from an external power source and convert the electrical energy into a wireless signal to charge the electric vehicle. One end of the plug 5 is electrically connected to the charging circuit board via a connecting line. When the plug 5 is connected to an external power source, electrical energy can be transmitted to the charging circuit board along the connecting line. The other end of the plug 5 is connected to the external power source, achieving stable power transmission. In this embodiment, the plug 5 is a triangular plug 5. Triangular plugs 5 typically have good mechanical fixation and can securely connect to the electric vehicle's socket. This structure helps prevent loosening of the connection due to vibration or impact. Due to the symmetry of the triangular structure, users can more easily and correctly install the plug 5 without worrying about orientation issues, which reduces errors during installation.

[0050] Furthermore, a foot pedal 4 is provided on one side of the second lifting part 32. The foot pedal 4 is used to adjust the angle of the charging base 2 relative to the support base 1. In this embodiment, the foot pedal 4 and the second lifting part 32 are integrally formed. The foot pedal 4 is located on one side of the second lifting part 32. When the user needs to lower the footrest to charge the electric vehicle, the user can step on the foot pedal 4 to lower the footrest to the ground and adjust the relative angle between the support base 1 and the charging base 2 by stepping on the foot pedal 4, so as to adjust the footrest to a suitable angle, thereby making the charging base 2 better fit with the ground transmitter, improving charging efficiency and stability, and facilitating user operation.

[0051] Furthermore, the connector 6 is a spherical structure. In this embodiment, the connector 6 is a universal ball joint, which allows the charging base 2 to rotate freely in multiple directions, thereby easily adjusting to the optimal charging angle and position. This design not only improves charging efficiency but also enhances the adaptability and practicality of the charging base 2, making the entire wireless charging foot support structure more flexible and convenient.

[0052] Furthermore, the bottom of the charging base 2 is made of plastic. Plastic has good wear resistance, resisting ground friction and abrasion, maintaining the flatness and smoothness of the bottom of the charging base 2. A certain degree of roughness and texture can be designed on the surface of the plastic to increase the friction between the charging base 2 and the ground, preventing the charging base 2 from sliding or shifting during use. The plastic material also has a certain degree of elasticity, which can absorb and buffer the impact force transmitted from the ground to a certain extent, protecting the charging base 2 and components such as the charging coil from damage. Furthermore, the plastic material has good insulation properties, effectively isolating current and preventing safety hazards such as short circuits or electric shocks.

[0053] Furthermore, the support base 1 can also be equipped with LED status lights to indicate to the user whether the vehicle is currently charging and whether charging is complete. The LED status lights allow the user to clearly see the current charging status of the electric vehicle, making it easy for them to monitor the process.

[0054] This utility model also provides an electric vehicle, including the aforementioned wireless charging footrest for electric vehicles, wherein the wireless charging footrest is installed on the vehicle body.
