[0002] With the accelerating pace of greening and intelligentization in urban transportation, two-wheeled electric vehicles have become an important tool for short-distance travel due to their convenience and environmental friendliness. 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 (such as opening the car body and adjusting the circuit layout), which is not only complicated and time-consuming, but may also damage the vehicle's sealing and the safety of the original wiring.

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

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

[0040] The lifting component 2 is fixedly connected to the support base 1, and the lifting component 2 is used to adjust the length of the foot support.

[0041] The charging base 3 is movably connected to the support base 1. The charging base 3 is provided with a charging coil, and the charging coil is electrically connected to the charging circuit board through a connecting line.

[0042] This invention solves the problem of cumbersome installation of 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 structurally modify their vehicles and directly connect to an external power source via the kickstand's plug 4 to achieve wireless charging, simplifying the charging process and improving installation convenience and vehicle compatibility. In this embodiment, the support base 1 is embedded with a charging circuit board, which converts the electrical energy provided by the external power source into a wireless charging signal. The wireless charging signal is transmitted to the electric vehicle's battery through the plug 4, thereby achieving wireless charging. The charging base 3 is movably connected to the support base 1, and its relative position can be adjusted by rotation or other means. The charging base 3 contains a charging coil, which is electrically connected to the charging circuit board via a connecting line. When the charging base 3 is aligned with an 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, realizing the transmission of electrical energy and the wireless charging function.

[0043] Furthermore, referring to Figure 2 , Figure 3 The support base 1 has a hollow structure and includes a first connecting part 11, a second connecting part 13 and a receiving part 12. The first connecting part 11 is used to fix the lifting component 2 to adjust the length of the foot support. The second connecting part 13 is used to movably connect with the charging base 3. The receiving part 12 is used to run wires and receive the charging circuit board.

[0044] The first connecting part 11, the second connecting part 13 and the receiving part 12 are all provided with wire through holes 7 so that connecting wires can pass through.

[0045] In this embodiment, the support base 1 is a hollow through-structure, including a first connecting part 11, a second connecting part 13, and a receiving part 12. The lifting assembly 2 is fixedly installed on the first connecting part 11, where the user can adjust the length of the footrest according to the height of the electric vehicle and usage needs, so that the length of the footrest can adapt to the height of the electric vehicle to accommodate different electric vehicle models. The second connecting part 13 is located at the other end of the support base 1 and is movably connected to the charging base 3. This movable connection allows the charging base 3 to rotate or tilt relative to the support base 1 to a certain extent, ensuring optimal alignment between the charging coil and the external wireless charging transmitter, thereby improving charging efficiency and stability. The receiving part 12 is a closed cavity, in which a charging circuit board is installed. The closed cavity design prevents external dust, moisture, and other impurities from entering the cavity, and the user cannot directly contact the circuit board, thereby reducing safety hazards caused by misoperation or short circuits. Furthermore, the receiving part 12 is also used for wiring. Through the wiring through-hole 7 and the receiving part 12, it can ensure that the connecting wires are neat and safely electrically connected to the charging circuit board, reducing wear and tear on exposed wires and interference from the external environment. The first connecting part 11, the second connecting part 13, and both ends of the accommodating part 12 are provided with through-holes 7. The connecting holes 7 at the top of the first connecting part 11 and the accommodating part 12 enable the connection lines of the plug 4 to be electrically connected to the charging circuit board. The connecting holes 7 at the bottom of the second connecting part 13 and the accommodating part 12 enable the connection lines of the charging coil to be electrically connected to the charging circuit board. Furthermore, the design of multiple connecting holes 7 can effectively dissipate the heat generated by the charging circuit board to the outside of the cavity, prevent overheating, and extend the service life of the circuit board.

[0046] Specifically, the support base 1 is made entirely of metal, while the sides of the housing 12 are made of plastic. The metal material possesses high strength and rigidity, capable of withstanding the weight of the electric vehicle without deformation. Furthermore, the high thermal conductivity of the metal quickly transfers the heat generated by the charging circuit board to the outside of the support base 1, preventing overheating damage and extending the device's lifespan. The metal surface can also be enhanced with anodizing and plating processes to improve corrosion resistance, adapting to harsh environments such as rain and salt spray, and preventing rust. The plastic material on the sides of the housing 12 effectively isolates the charging circuit board from the external environment, preventing safety hazards caused by short circuits or misoperation. Additionally, plastic is lighter than metal, helping to reduce the overall weight of the kickstand and charging components, improving portability and user comfort.

[0047] Furthermore, referring to Figure 5The charging base 3 is provided with mounting ears 31, which are fixedly connected to the charging base 3. The mounting ears 31 have mounting holes 32, and the support base 1 has screw holes corresponding to the mounting holes 32. The charging base 3 is movably connected to the second connecting part 13 through the mounting holes 32, screw holes, and screws. In this embodiment, a pair of mounting ears 31 are symmetrically arranged on the charging base 3, and mounting holes 32 are provided on the mounting ears 31. The charging base 3 is movably connected to the second connecting part 13 through the mounting holes 32 and screws, allowing the charging base 3 to rotate or tilt relative to the second connecting part 13 to adapt to different charging needs and ground conditions. This enables the charging base 3 to align with the external wireless charging transmitter, thereby improving charging efficiency and stability. Furthermore, since the charging base 3 and the support base 1 are detachably connected by screws, when the charging base 3 wears out due to long-term use or the charging coil inside the charging base 3 malfunctions, the user can disassemble the charging base 3 for replacement or repair without replacing the entire support, thus facilitating user replacement or repair and reducing maintenance costs. It should be noted that the charging base 3 can also be connected to the second connecting part 13 by a hinge connection, a sliding connection, or other methods.

[0048] Furthermore, the charging base 3 has a wiring connection hole 33. The charging coil is electrically connected to the charging circuit board through a connecting wire passing through the wiring connection hole 33, the first connecting part 11, and the wiring through hole 7 at the bottom of the receiving part 12. In this embodiment, the connecting wire of the charging coil passes through the wiring through hole 7 and the wiring connection hole 33 to be electrically connected 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 connecting wire of the charging coil and the charging circuit board can be soldered, plugged in, or other electrical connection methods.

[0049] Furthermore, the wireless charging stand also includes a plug 4. One end of the plug 4 is electrically connected to the charging circuit board via a connecting line at the top of the first connecting part 11 and the receiving part 12, and the other end is electrically connected to an external power source. In this embodiment, the plug 4 is used to transmit electrical energy. Through the plug 4, 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 4 is electrically connected to the charging circuit board via a connecting line at the top of the first connecting part 11 and the receiving part 12. When the plug 4 is connected to an external power source, electrical energy can be transmitted to the charging circuit board along the connecting line.

[0050] The other end of plug 4 is connected to an external power source to achieve stable power transmission. In this embodiment, plug 4 is a triangular plug 4. Triangular plug 4 usually has good mechanical fixation and can be firmly connected to the socket of the electric vehicle. This structure helps to prevent the connection from loosening due to vibration or impact. Due to the symmetry of the triangular structure, users can more easily and correctly install plug 4 without worrying about orientation issues, which reduces errors during the installation process.

[0051] Furthermore, referring to Figure 4 The lifting assembly 2 includes a lifting frame 21 and a fixing member 22. The lifting frame 21 has several adjustment holes 23 on both sides. The first connecting part 11 has screw holes corresponding to the adjustment holes 23. The lifting frame 21 is fixedly connected to the first connecting part 11 via the fixing member 22 passing through the adjustment holes 23 and the screw holes. In this embodiment, the lifting frame 21 has multiple rows of adjustment holes 23 on both sides, arranged at predetermined intervals, providing multiple adjustment positions for the user. The user can adjust the length of the kickstand by selecting different adjustment holes 23 to adapt to different electric vehicle heights. When the user needs to adjust the length of the kickstand, first loosen the fixing member 22 to allow the lifting frame 21 to move freely on the first connecting part 11. Then, the user selects a suitable adjustment hole 23 according to the height of the electric vehicle and tightens the fixing member 22 through the adjustment hole 23 and the corresponding screw hole. The fixing member 22 is a screw. It should be noted that the lifting assembly 2 can also be fixed to the first connecting part 11 by snap-fit ​​fixing, pin fixing, or other fixing methods.

[0052] Furthermore, the support base 1 is provided with a limiting member 6, and the lifting frame 21 is provided with a limiting groove 24. The limiting member 6 can engage with the limiting groove 24 to limit the sliding distance of the lifting frame 21. Specifically, the support base 1 has a through hole, and the limiting member 6 is threaded into the through hole. Multiple through holes can be provided along the height direction of the support base 1 to adjust the position of the limiting member 6. The lifting frame 21 is provided with a limiting groove 24, which is a U-shaped groove. As the lifting frame 21 slides, the limiting groove 24 will move along the limiting member 6. Through the setting of the limiting groove 24 and the limiting member 6, the stable sliding of the lifting frame 21 in the vertical direction is ensured, avoiding installation difficulties of the lifting frame 21 due to shaking or displacement. When the lifting frame 21 slides to a certain position, the limiting member 6 can limit the further sliding of the lifting frame 21 and prevent the lifting frame 21 from falling off due to excessive sliding.

[0053] Furthermore, a foot pedal 5 is provided on one side of the support base 1. The foot pedal 5 is rotatable relative to the support base 1 and is used to adjust the angle of the charging base 3 relative to the support base 1. In this embodiment, a protruding mounting plate is provided on one side of the support base 1. The mounting plate has an arc-shaped hole 51 and a fixing hole. The foot pedal 5 is fixedly mounted on the mounting plate with screws and the fixing hole. The angle of the foot pedal 5 can be adjusted within a certain range through the arc-shaped hole 51, thereby driving the support base 1 to rotate and thus adjusting the angle of the support base 1 relative to the charging base 3. Through the design of the foot pedal 5, the user can directly adjust the angle of the foot pedal 5 with their foot, so that the charging base 3 can better fit with the ground transmitter, improving charging efficiency and stability, and facilitating user operation.

[0054] Furthermore, the bottom of the charging base 3 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 3. A certain degree of roughness and texture can be designed on the surface of the plastic to increase the friction between the charging base 3 and the ground, preventing the charging base 3 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 3 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.

[0055] 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.

[0056] 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.
