Referring to fig. 4b and 4c, as the automobile 200 moves, under the pressure of the automobile 200, the vehicle-mounted power receiving platform 13 gradually presses the contact 112 of the ground power transmitting platform 11, so that the contact 112 of the ground power transmitting platform 11 transmits the pressure to the deformation component 111, and the deformation component 111 is compressed, so that the contact 112 moves towards the ground 105.

In one embodiment, referring to fig. 5d and 5e, the present embodiment is substantially the same as the embodiment shown in fig. 5a to 5c, except that the ground power emission platform further includes a guide, one end of the guide is connected to the base 1111, and the other end opposite to the base 1111 is connected to the contact 112, and the guide is used to control the direction of the contact 112 moving towards the base 1111.

Through setting up the guide, can make contact 112 move according to the predetermined route when moving, avoid contact 112 to produce unnecessary and rock, guarantee the reliability of wireless charging.

Optionally, the guiding element includes a connecting rod 1118 and hinge bases 1117, two ends of the connecting rod 1118 are respectively provided with a hinge base 1117, one of the hinge bases 1117 is fixedly mounted to the base 1111, the other hinge base 1117 is fixedly mounted to the contact element 112, and the connecting rod 1118 is rotatably connected to both the hinge bases 1117.

The link 1118 is made of a rigid material, and when the contact 112 is pressed and moves toward the base 1111, the link 1118 rotates with respect to the two hinge bases 1117, and on one hand, the entire contact 112 moves toward the base 1111, and on the other hand, the movement direction of the contact 112 is restricted by the link 1118, i.e., the movement path of the end point where the link 1118 is connected to the hinge base 1117 on the contact 112 moves, and the movement path of the contact 112 is curved because the link 1118 is rotatably connected to the hinge base 1117 on the base 1111.

Further, the hinge base 1117 connected to the base 1111 is located on a side of the vehicle-mounted power receiving platform 13 first contacting the contact member 112, so that when the vehicle enters the parking space for wireless charging, the moving direction of the contact member 112 has substantially the same component as the vehicle driving direction, so that the contact between the vehicle-mounted power receiving platform 13 and the contact member 112 is smoother.

Optionally, the hinge base 1117 is provided with two pressing pieces 17a, the pressing pieces 17a have elasticity, and the two pressing pieces 17a are always elastically pressed on two opposite sides of the connecting rod 1118.

The main body of the pressing piece 17a is fixed on the hinge base 1117, at least part of the pressing piece is pressed against the end of the connecting rod 1118 connected with the hinge base 1117, and the two sides opposite to the connecting rod 1118 are pressed, so that on one hand, the effect of stable support is achieved, the connecting rod 1118 cannot shake left and right, the contact piece 112 is kept stable and cannot topple over in the initial state, on the other hand, when the contact piece 112 is subjected to a force which forms an included angle with the plane where the connecting rod 1118 rotates, certain deformation can be generated due to the elasticity of the pressing piece 17a, the impact of the force can be buffered, and after the force is removed, the contact piece can be restored to the initial state.

In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like, are used for describing the orientation or positional relationship based on the drawings, and are only used for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the present application.

While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
