Embodiment 1

[0028] Such as figure 1 Shown is a schematic diagram of an embodiment of a wireless charging device based on electric vehicles according to the present invention. The wireless charging device includes a vehicle position positioning layer (4) located below the parking charging area, and then a There is space for a charging unit. The charging unit includes a three-dimensional moving device, which is used to drive the primary coil (5-2) (also called a wireless charging transmitting device) to move in space. The three-dimensional moving device includes a horizontal direction driving mechanism (6) and a vertical direction driving mechanism (7). The horizontal direction driving mechanism (6) specifically includes a horizontal guide rod mounting bracket (6-1), a horizontal X-axis direction driving motor (6-2) and a horizontal Y-axis direction driving motor (6-3), wherein the horizontal X-axis direction It is set as the parking direction of the electric vehicle or the direction of t...

Embodiment 2

[0042] The difference between the present embodiment and the first embodiment is that an upwardly convex protruding portion is provided between the strip-shaped regions, and the protruding portion is used to increase the rising space of the primary coil. The specific shape of the protrusion can be designed by itself according to the actual situation.

Embodiment 3

[0044] The difference between the present embodiment and the first embodiment is that a hollow hole is provided between the band-shaped regions, and the hollow hole is used to increase the rising space of the primary coil. The specific shape of the hollow hole can be designed according to the actual situation.

Abstract

The invention relates to a wireless charging device based on an electric vehicle, and belongs to the field of wireless charging application of new energy electric vehicles. The wireless charging device comprises a vehicle position positioning layer and a charging unit, wherein the vehicle position positioning layer comprises a pressure sensor array used for positioning an electric vehicle parkingposition, the charging unit comprises a primary side coil, a horizontal driving mechanism and a controller, the controller is in control connection with the horizontal driving mechanism, the controller is in sampling connection with the pressure sensor array, and the horizontal driving mechanism is used for driving the primary side coil to move in the horizontal plane. According to the wireless charging device, a specific parking position of the vehicle is acquired according to the pressure distribution of the vehicle through the pressure sensor array, an actual position of the vehicle-mountedsecondary side coil is obtained through combination with a vehicle file, and then the controller controls the horizontal driving mechanism to achieve rapid and accurate matching alignment between theoriginal and secondary coil.

Description

technical field [0001] The invention relates to a wireless charging device based on electric vehicles, which belongs to the application field of wireless charging for new energy electric vehicles. Background technique [0002] Wireless charging technology is a new charging technology. At present, the magnetic field coupling wireless charging technology is suitable for high-power wireless charging of electric vehicles. In the magnetic field coupling wireless charging technology, when the center of the primary coil and the secondary coil are aligned, the charging efficiency is the highest. If the coupling between the primary coil and the secondary coil deviates, serious magnetic flux leakage will occur, which will affect the charging efficiency; When the working air gap between the coil and the secondary coil is within 200mm, the working air gap basically has no effect on the charging efficiency, but once the working air gap exceeds 200mm, the charging efficiency is inversely ...
