The wireless charging kickstand comprises a kickstand 10 and a support rod 20, the support rod 20 is movably connected with the kickstand 10, and the support rod 20 is hinged to the vehicle body. When the kickstand 10 supports the vehicle body, the angle of the kickstand 10 relative to the support rod 20 can be rotated, so that the bottom surface of the kickstand 10 can be completely attached to the ground, so that the wireless charging kickstand can support the vehicle body more stably.

[0043] Referring to Figures 2-4 The first electromagnetic coil 11 is arranged in the kickstand 10, and the first electromagnetic coil 11 is connected with the battery in the two-wheeled electric vehicle through a wire.

Through the electromagnetic wireless charging of the kickstand 10 and the "socket" of the battery charging base, the product itself reaches the IP67 protection level, and the product is waterproof and dustproof.

[0044] The kickstand 10 comprises a base 12 and a clamping part connected with each other, the first electromagnetic coil 11 is fixedly connected in the base 12, and the bottom surface of the base 12 is in contact with the ground. The support rod 20 comprises a mounting valve head 21 and a rotating valve head 22, the mounting valve head 21 is connected with the vehicle body through a pivot shaft, and the rotating valve head 22 is movably connected with the clamping part.

[0045] The rotating valve head 22 comprises a connecting rod part 221 and a ball head part 222 connected with each other. The clamping part comprises a first clamping part 131 and a second clamping part 132, a first hemispherical groove is formed on the first clamping part 131, a second hemispherical groove is formed on the second clamping part 132, and the first hemispherical groove and the second hemispherical groove are surrounded to form a connecting ball groove 133.

[0046] The connecting mode between the rotating valve head 22 and the kickstand 10 is a universal ball head, which can fix the relative angle between the support rod 20 and the kickstand 10 in a natural state, and can also adaptively adjust the relative angle between the support rod 20 and the kickstand 10 in a stressed state, so that the kickstand 10 can be more attached to the ground, and the vehicle can be more stably supported.

[0047] The first clamping part 131 and the second clamping part 132 are connected by a fixing member such as a screw, and are convenient to assemble during production. In alternative embodiments, the clamping part can also not be provided in a split structure, and a deformation slot can be formed in the clamping part and communicated with the connecting ball groove 133. Under the action of the deformation slot, the ball head 222 can be smoothly installed, and the clamping part can also tightly clamp the ball head 222.

[0048] In alternative embodiments, a universal joint or a self-aligning bearing can also be used to connect the rotary valve head 22 and the clamping part, as long as the angle adaptive adjustment between the rotary valve head 22 and the clamping part can be achieved, and the present embodiment is not specifically limited.

[0049] Referring to Figure 4 and Figure 5 , the rotary valve head 22 is provided with a first threading hole 223, a first wire passing channel 224 and a second threading hole 225 which are communicated with each other. The opening of the first threading hole 223 is located at the connecting rod 221, and the opening of the second threading hole 225 is located at the ball head 222. Figure 6 The base 12 is provided with a second wire passing channel 121 which is communicated with the connecting ball groove 133.

[0050] The wire is led out from the battery in the electric vehicle and sequentially passes through the first threading hole 223, the first wire passing channel 224, the second threading hole 225, the connecting ball groove 133 and the second wire passing channel 121 and is connected to the first electromagnetic coil 11. The connection of the wire is more secure, and the current can be smoothly transmitted to the battery.

[0051] Referring to Figure 5 , the distance between the installation valve head 21 and the rotary valve head 22 can be adjusted in the axial direction. The rotary valve head 22 is connected with the installation valve head 21 through the telescopic rod 23, and the distance between the installation valve head 21 and the rotary valve head 22 is adjusted through the telescopic rod 23.

[0052] The telescopic rod 23 includes a partition plate 231 and two sliding rods 232 connected to both sides of the partition plate 231. The installation valve head 21 and the rotary valve head 22 are both provided with a sliding groove 226 at one end facing each other, and the sliding rod 232 is slidingly connected in the sliding groove 226. The installation valve head 21 and the rotary valve head 22 are both provided with a fixed hole 227 communicated with the sliding groove 226, and a fastener (not shown in the figure) is threadedly connected in the fixed hole 227. The sliding rod 232 is provided with a limiting slot 233 matched with the fastener. The fastener passes through the fixed hole 227 and abuts against the slot wall of the limiting slot 233.

[0053] The telescopic rod 23 is used to connect the mounting valve head 21 and the rotating valve head 22, and the distance between the mounting valve head 21 and the rotating valve head 22 can be adjusted according to the size of the electric vehicle, that is, the length of the whole foot support 10 can be adjusted. Therefore, the foot support 10 can be matched with various types of electric vehicles, and the foot support 10 can well support the corresponding type of electric vehicle after being adjusted once during installation, and the supporting effect and stability of the foot support 10 are better.

[0054] In optional embodiments, the rotating valve head 22 and the mounting valve head 21 can be directly slidably connected, or one end of the telescopic rod 23 is slidably connected with the mounting valve head 21 and the other end is fixedly connected with the rotating valve head 22, or one end of the telescopic rod 23 is fixedly connected with the mounting valve head 21 and the other end is slidably connected with the rotating valve head 22. As long as the structure between the mounting valve head 21 and the rotating valve head 22 can adjust the distance along the axial direction, the specific embodiments are not limited.

[0055] The mounting valve head 21 has an elbow portion 211 located in the middle of the two ends, and the elbow portion 211 is arranged in a circular arc shape. Since the elbow portion 211 is arranged, the axes of the two ends of the mounting valve head 21 are not located on the same straight line, so that the stress concentration on the mounting valve head 21 can be reduced, and the supporting strength and stability of the mounting valve head 21 can be ensured.

[0056] The rotating valve head 22 is fixedly connected with a footrest 228, and the footrest 228 is arranged in a triangular shape. The footrest 228 facilitates opening and folding of the footrest.

[0057] Referring to Figure 7 The bottom surface of the base 12 is provided with a plurality of anti-skid protrusions 122. The anti-skid protrusions 122 can increase the friction between the base 12 and the ground, so that the support of the foot support 10 is more stable.

[0058] An embodiment of the utility model provides a wireless charging base for charging the above-mentioned wireless charging foot support, referring to Figure 8 and Figure 9 The wireless charging base comprises a cover body 30 and a box body 40 which are connected with each other, and the cover body 30 and the box body 40 form a mounting cavity. A second electromagnetic coil 41 is fixedly connected in the mounting cavity. A third wire hole 42 is arranged on the side wall of the box body 40, and a wire for supplying power to the second electromagnetic coil 41 passes out through the third wire hole 42.

[0059] The second electromagnetic coil 41 cooperates with the first electromagnetic coil 11 to supply power to the second electromagnetic coil 41. When the first electromagnetic coil 11 is close to the second electromagnetic coil 41, an alternating magnetic field is generated. Therefore, the magnetic field of the wireless charging base will generate an induced current on the first electromagnetic coil 11 of the foot support 10 through electromagnetic induction. After rectification and adjustment, the induced current is supplied to the battery of the electric vehicle for charging. In the charging system, the magnetic resonance principle is used.

[0060] The wireless charging base and the wireless charging foot prop are designed as resonance circuits of a specific frequency. By adjusting the frequency, the wireless charging base and the wireless charging foot prop can efficiently transmit energy. In this way, charging can be achieved at a long distance (a few centimeters to tens of centimeters), the charging efficiency is improved, the voltage and current states during charging are monitored in real time, all charging processes are accurately controlled, and there is sufficient convenience for users, who only need to place the charging device on the charging board to charge, thereby avoiding the risk of short circuit. In addition, since there is no opening for contact, the risk of water and dust entering the interior of the device is reduced, and the use of the device is safe, secure and convenient.

[0061] It should be noted that the wireless charging base provided in the embodiment is embedded in the ground, and the upper end surface of the cover body 30 is flush with the ground, which is convenient for users to park.

[0062] The top surface of the cover body 30, which is away from the box body 40, is provided with a plurality of limiting ribs 31, which substantially enclose a circular shape matching the base 12 of the foot prop 10, and can guide and limit the foot prop 10. When the user parks, it is more convenient to make the foot prop 10 correspond to the charging position of the wireless charging base.

[0063] Referring to Figure 10 The bottom surface of the cover body 30 is provided with a mounting bracket, which includes two locking lugs 32 fixedly connected to the bottom surface of the cover body 30 and a fixed rod 33 connected between the two locking lugs 32. The two locking lugs 32 are respectively located on the two sides of the radial direction of the second electromagnetic coil 41, that is, the two ends of the fixed rod 33 extend to the two sides of the second electromagnetic coil 41. Therefore, the fixed rod 33 can be used to fix and limit the second electromagnetic coil 41, and the structure is simple and easy to install. Moreover, the fixed rod 33 presses the second electromagnetic coil 41 on the bottom surface of the cover body 30, so that the second electromagnetic coil 41 is closer to the ground side, thereby ensuring better induction effect.

[0064] In order to make the connection of the second electromagnetic coil 41 more firm, the bottom surface of the cover body 30 is fixedly connected with at least two limiting lugs 34. Any one of the limiting lugs 34 is located on one side of the fixed rod 33, and any other limiting lug 34 is located on the other side of the fixed rod 33. As an example, only two limiting lugs 34 are provided in the embodiment, and the two limiting lugs 34 are arranged symmetrically about the fixed rod 33. The limiting lugs 34 can prevent the second electromagnetic coil 41 from being separated from one side of the fixed rod 33, thereby ensuring the stability of the connection.

[0065] An embodiment of the utility model provides a kind of wireless charging system, referring to Figure 11, including a power supply device, a controller (not shown in the figure), the wireless charging foot support and the wireless charging base. The controller is electrically connected with the power supply device and the wireless charging base, and the power supply device is used for powering the wireless charging base. When the wireless charging foot support is attached to the wireless charging base, an alternating magnetic field is generated, and the magnetic field of the wireless charging base will generate an induced current on the first electromagnetic coil 11 of the foot support 10 through electromagnetic induction. After rectification and regulation, the induced current is supplied to the battery of the electric vehicle for charging.

[0066] This charging method does not need to plug in the charger, only needs to stop the electric vehicle at the designated position, which improves the charging efficiency and has sufficient convenience, avoids the risk of short circuit. And because the contact has no opening, the risk of water and dust entering the internal part of the device is reduced, realizing the comfort, safety and convenience of electricity use.
