Embodiment 1

[0026] Such as figure 1 As shown, the electric vehicle wireless charging system includes a wireless charging transmitting board 1 and a wireless charging receiving board 2 , and also includes a supporting platform 3 for parking the electric vehicle and a supporting assembly 4 for supporting the wireless charging transmitting board 1 . The wireless charging receiving board 2 is arranged on the bottom of the electric vehicle with its receiving surface facing downward, and at least a position adjustment mechanism capable of adjusting the height of the wireless charging transmitting board 1 is provided between the support assembly 4 and the supporting platform 3 .

[0027] Specifically, the support platform 3 can be the ground or a metal frame. If the ground is selected as the support platform 3, the position adjustment mechanism can be buried under the ground, and the wireless charging launch board 1 is flush with the ground, reducing the occupation of ground space. If selected ...

Embodiment 2

[0034] Such as figure 2 As shown, compared with Embodiment 1, the difference lies in the height adjustment part in the position adjustment mechanism. The position adjustment mechanism of Embodiment 2 includes a base plate 5, a motor 6 and a guide shaft 9 fixed on the base plate 5, and is sleeved on the support assembly. 4 and the guide block 10 fixed axially with the support assembly 4, the screw mandrel 11 which is threadedly connected with the guide block 10 and arranged parallel to the guide shaft 9, the guide block 10 is passed through the guide shaft 9, and the screw mandrel 11 is driven by a motor 6 drives.

Abstract

The invention provides an electric automobile wireless charging system and belongs to the technical field of automobiles. The electric automobile wireless charging system solves the problems that butt joint and match of an existing primary side coil and an existing secondary side coil are difficult. The electric automobile wireless charging system comprises a wireless charging emitting board and a wireless charging receiving board and further comprises a support platform for parking an electric automobile and a support component used for supporting the wireless charging emitting board. The wireless charging receiving board is arranged at the bottom of the electric automobile and a receiving face of the wireless charging receiving board faces a lower bottom face. At least a position adjusting mechanism capable of adjusting the height of the wireless charging emitting board is arranged between the support component and the support platform. The height of the wireless charging emitting board can be rapidly adjusted according to the position of the electric automobile, the distance between the wireless charging emitting board and the wireless charging receiving board is shortened, electricity transmission loss caused by the positions of the electric automobile and the wireless charging emitting board is effectively reduced, energy transmission efficiency is improved and radiation is relatively reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a wireless charging system for electric vehicles.
