Wherein, the color of the laser projection guide line and/or line style are different from the T-shaped guide line.
The electric vehicle wireless charging alignment control device that this programme provides, the guide line emitted by laser and ground
Contraposition guide line constantly overlap to be agreed with the perfection for reaching charge position so that charge efficiency improves, and saves time and electricity
Power.
It is the utility model wireless charging aligning structure schematic diagram with reference to Fig. 1.The electric vehicle wireless charging of the utility model
Electric alignment system, the parking stall including wireless charging alignment control device and equipped with charge position, including electric energy receiving coil
1st, camera 2, laser 3, image processing module 4, laser projection guide line 5, ground line of reference 6, electric energy transmitting coil 7, aobvious
Show device 8, charging vehicle 9 and wireless charging parking stall 10.The laser projection guide line 5 includes guiding for the projection of front and rear contraposition
Line 5-1 (the second guide line) and the projection guide line 5-2 (the first guide line) of left and right contraposition；Ground line of reference is included for left and right
The ground line of reference 6-1 (vertical curve) of the contraposition and ground line of reference 6-2 (x wire) for front and rear contraposition, to increase ground ginseng
