[0026] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Furthermore, it should be understood that although the terms first, second, etc. may be used herein to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from each other. For example, a first mounting hole may be referred to as a second mounting hole, and similarly, a second mounting hole may also be referred to as a first mounting hole, which does not deviate from the scope of protection of the present application.

[0028] The present application embodiment provides a wireless charging foot support for an electric vehicle, such as Figure 1 , 2 As shown, it includes a base 1 formed with a accommodating cavity 11, a kick support body 3 for connecting to an electric vehicle, a connector 2 connecting the base 1 and the kick support body 3, and a wiring member 4 connected to the connector 2, the connector 2 is arranged at an angle to the base 1, the wiring member 4 is arranged between the angle formed by the connector 2 and the base 1, and the wiring member 4 forms a wiring groove 41 connected to the accommodating cavity 11.

[0029] The kickstand of an electric vehicle is usually made of metal due to strength requirements. For an electric vehicle with a wireless charging receiving coil set on the kickstand, the kickstand body 3 is also made of metal. However, in order to avoid the influence of metal on the receiving coil signal, the component that accommodates the receiving coil is usually made of plastic and connected to the kickstand body 3 to form the electric vehicle kickstand. Figure 2 In the figure, the base 1, the connecting member 2, the wiring member 4 and the pedal member 6 described below are integrally arranged and are usually made of plastic.

[0030] The electric vehicle wireless charging foot support provided by the present application connects the wiring component 4 with the connector 2, and performs wiring by connecting with the accommodating cavity 11 of the base 1. The wiring method of the present application is to extend a wiring groove 41 connected to the connector 2 from the base 1. Since the wiring component 4 is a plastic component, the wire body will not be worn due to friction with the notch of the wiring groove 41 after extending from the wiring groove 41, and it can also avoid the eddy current effect generated by the electromagnetic field formed by the receiving coil, causing the metal foot support to heat up. And the wiring component 4 is arranged between the angle formed by the connector 2 and the base 1, that is, when the foot support is supported on the ground, the wiring component 4 is located below the connector 2, and the wire body can be blocked by the connector 2 and the foot support body 3 after extending from the wiring groove 41, without affecting the appearance.

[0031] In some embodiments, the extension direction of the wiring groove 41 is the same as the extension direction of the connector 2. Figure 1 In the figure, the connecting member 2 is set at an angle to the base 1, and the extension direction of the foot support body 3 connected to the connecting member 2 is also the same as the extension direction of the connecting member 2. Therefore, the extension direction of the wiring groove 41 is the same as the extension direction of the foot support body 3, that is, the wire body extends out of the wiring groove 41 and is parallel to the foot support body 3, which is conducive to fixing the wire body extending out of the wiring groove 41 to the foot support body 3.

[0032] In some embodiments, the base 1 is oval in shape. Figure 2 The oval is similar to a standard track and field stadium, consisting of two semicircles with a rectangle in the middle.

[0033] In some embodiments, a receiving coil is provided in the accommodating cavity 11, and the wireless charging foot support of the electric vehicle also includes an aviation plug 5 connected to the receiving coil. The receiving coil is provided in the accommodating cavity 11 of the base 1 (the receiving coil is not shown in the figure), and one end of the receiving coil is extended through the wiring groove 41 connected to the accommodating cavity 11 and connected to an aviation plug 5. When the electric vehicle is wirelessly charged, in addition to the receiving coil for receiving the energy signal, a receiving end main control board is also required to be provided on the electric vehicle, which is used to process the energy signal received by the receiving coil and transmit it to the battery of the electric vehicle, and the installation position of the receiving end main control board is not fixed. In order to facilitate the connection between the receiving coil and the receiving end main control board, the present application connects an aviation plug 5 after the receiving coil is extended from the wiring groove 41, and the receiving end main control board is also connected to an aviation plug, which is plugged into the aviation plug 5 on the foot support.

[0034] In some embodiments, a footrest 6 is provided on the side of the connector 2 away from the wiring groove 41. The connector 2 extends in a direction close to the electric vehicle, the wiring member 4 is hidden between the angle formed by the connector 2 and the base 1, and the footrest 6 is provided on the side of the connector 2 away from the wiring groove 41, that is, on the side of the connector 2 away from the electric vehicle, so that the user can use the footrest 6 to put down the footrest to support it on the ground or to push it off the ground for riding.

[0035] In some embodiments, the connector 2 is provided with a connection groove 21 for accommodating one end of the foot support body 3, and the opening direction of the connection groove 21 is the same as the extension direction of the connector 2. The connector 2 is provided with a connection groove 21 to accommodate one end of the foot support in the connection groove 21, and the opening direction of the connection groove 21 and the opening direction of the wiring groove 41 are the same as the extension direction of the connector 2, so that the foot support body 3 and the wire body are in the same direction, and the wire body can be fixed to the foot support body 3 to avoid the wire body being messy and unfixed.

[0036] In some embodiments, the connection slot 21 is spaced apart from the accommodating chamber 11 of the base 1, that is, the connection slot 21 is not connected to the accommodating chamber 11. One end of the foot support body 3 is disposed in the connection slot 21, so that a gap is formed between the foot support body 3 and the connection slot 21, and dust or rainwater can enter the bottom of the connection slot 21 from the gap formed between the foot support body 3 and the connection slot 21. If the connection slot 21 is connected to the accommodating chamber 11, dust or rainwater may enter the accommodating chamber 11 and contaminate the receiving coil.

[0037] In some embodiments, a first mounting hole 22 is provided on the side of the connection slot 21, and a second mounting hole 31 is provided on the foot support body 3, and the connection member 2 and the foot support body 3 are connected through the first mounting hole 22 and the second mounting hole 31. If the foot support body 3 and the connection member 2 are only connected through the connection slot 21, even if the connection slot 21 and the foot support body 3 are interference fit, the connection strength between the two cannot be guaranteed. Therefore, by providing the first mounting hole 22 in the connection slot 21 and the second mounting hole 31 in the foot support body 3, the foot support body 3 and the connection member 2 are fixed by screws or the like passing through the first mounting hole 22 and the second mounting hole 31.

[0038] In some embodiments, a rotation hole 32 is formed at one end of the foot support body 3 away from the connector 2, and the electric vehicle wireless charging foot support is connected to the electric vehicle through the rotation hole 32 and rotates with the rotation hole 32 as the center. Figure 5 In the figure, one end of the foot support body 3 is provided with two rotating holes 32, one large and one small. The direction of the line connecting the centers of the two rotating holes 32, or the direction in which the rotating holes 32 are opened, is roughly parallel to the spacing direction between the pedal member 6 and the wiring member 4. After the foot support is connected to the electric vehicle, it rotates with the rotating hole 32 as the center.

[0039] An embodiment of the present application also provides an electric vehicle wireless charging device, including a charging cabinet, a wireless charging module and the aforementioned electric vehicle wireless charging foot support.
