Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wireless charging technology, specifically referring to a wireless charging alignment device for electric vehicles. Background Technology
[0002] In recent years, electric vehicles have rapidly gained popularity due to their environmental friendliness and high efficiency. Wireless charging technology, as a new charging method that eliminates the need for plugging and unplugging charging cables, is convenient to operate, and highly safe, and is gradually becoming an important development direction in the field of electric vehicle charging. However, in practical applications, the alignment problem of wireless charging systems severely restricts their charging efficiency and stability.
[0003] Most existing wireless charging alignment devices for electric vehicles suffer from a single adjustment dimension, with common designs only allowing for lateral or longitudinal movement of the transmitting coil within a horizontal plane. When a vehicle is parked in an irregular position, these devices cannot effectively adjust the transmitting coil, resulting in inaccurate alignment between the charging coil and the vehicle's receiver, thus reducing charging efficiency and even causing charging failure. While some devices with multi-dimensional adjustment capabilities can adjust the position of the transmitting coil to some extent, they struggle to precisely adapt to differences in chassis height and angle among different vehicle models, leading to unstable energy transmission and significant energy loss during charging. Utility Model Content
[0004] To address the problems of limited adjustment dimensions and inability to accurately match the chassis height and angle of different vehicle models in the existing wireless charging alignment devices, this invention provides a wireless charging alignment device for electric vehicles.
[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A wireless charging alignment device for electric vehicles includes a base plate and a transmitting coil. The base plate is provided with a driving assembly, and a support plate is connected to the top of the driving assembly. The support plate is provided with a left-right adjustment assembly, and a support box is connected to the left-right adjustment assembly. A height adjustment assembly is provided inside the support box. A slot is opened on the top of the support box. The height adjustment assembly includes a rotary motor fixed to the outer wall of the support box, a bidirectional lead screw rotatably disposed in the slot, and a connecting rod. The output end of the rotary motor passes through the side wall of the support box and is connected to the end of the bidirectional lead screw. The two ends of the bidirectional lead screw are respectively threaded to a first lead screw pair and a second lead screw pair. Two sets of connecting rods are symmetrically arranged, and the two sets of connecting rods are inclined towards the middle of the bidirectional lead screw. Their bottoms are respectively hinged to the top of the first lead screw pair and the second lead screw pair. A top plate parallel to the support plate is provided on the upper side of the support box. The top of the connecting rod is hinged to the bottom wall of the top plate. A rotating disk is rotatably disposed in the middle of the top plate, and the transmitting coil is fixed to the top center of the rotating disk.
[0006] As a preferred embodiment of this utility model, a horizontal groove is provided in the top center of the base plate, and a rectangular groove is provided in the side of the base plate, with the horizontal groove and the rectangular groove located on the same horizontal axis.
[0007] As a preferred technical solution of this utility model, the driving assembly includes a drive motor fixed in a rectangular groove, a threaded rod horizontally rotatable in a transverse groove, and a sleeve block threadedly connected to the threaded rod. The output end of the drive motor passes through the rectangular groove and is connected to the end of the threaded rod.

[0011] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:
[0012] By employing a combination of a drive mechanism, left-right adjustment mechanism, height adjustment mechanism, and telescopic cylinder, precise adjustment of the transmitting coil is achieved in four dimensions: lateral, longitudinal, height, and tilt angle. The drive mechanism and left-right adjustment mechanism work together to compensate for planar position deviations when the vehicle is parked; the height adjustment mechanism adapts to differences in chassis height among different vehicle models; and the telescopic cylinder drives a rotating disc to adjust the tilt angle of the transmitting coil, compensating for pitch or tilt postures when the vehicle is parked.

The present invention will be further described in detail below with reference to the accompanying drawings.
[0021] like Figure 1-4As shown, the present invention provides a wireless charging alignment device for electric vehicles, comprising a base plate 1 and a transmitting coil 2. A driving assembly 3 is mounted on the base plate 1, and a support plate 4 is connected to the top of the driving assembly 3. A left-right adjustment assembly 5 is mounted on the support plate 4, and a support box 6 is connected to the left-right adjustment assembly 5. A height adjustment assembly 7 is located inside the support box 6. A slot 8 is formed in the top of the support box 6. The height adjustment assembly 7 includes a rotary motor 9 fixed to the outer wall of the support box 6, a bidirectional lead screw 10 rotatably disposed within the slot 8, and connecting rods 11. The output end of the rotary motor 9 passes through the side wall of the support box 6 and is connected to the end of the bidirectional lead screw 10. A first lead screw pair 12 and a second lead screw pair 13 are threaded to both ends of the bidirectional lead screw 10, respectively. The connecting rods 11 are symmetrically arranged. Two sets of connecting rods 11 are inclined towards the middle of the bidirectional lead screw 10. Their bottoms are respectively hinged to the top of the first lead screw pair 12 and the second lead screw pair 13. The upper side of the support box 6 is provided with a top plate 14 parallel to the support plate 4. The top of the connecting rod 11 is hinged to the bottom wall of the top plate 14. A rotating disk 15 is rotatably arranged in the middle of the top plate 14. The transmitting coil 2 is fixed to the top of the rotating disk 15. The rotary motor 9 drives the bidirectional lead screw 10 to rotate. The first lead screw pair 12 and the second lead screw pair 13 move towards or away from each other because their threads have opposite directions. This causes the connecting rod 11 to swing around the hinge point, thereby pushing the top plate 14 to rise and fall vertically. This converts the rotational motion into vertical lifting motion, realizing the adjustment of the height position of the transmitting coil 2 to adapt to the differences in chassis height of different vehicle models.
[0022] like Figure 1-4 As shown, a horizontal groove 16 is provided in the top center of the base plate 1, and a rectangular groove 17 is provided in the side of the base plate 1. The horizontal groove 16 and the rectangular groove 17 are located on the same horizontal axis. The driving assembly 3 includes a drive motor 18 fixed in the rectangular groove 17, a threaded rod 19 horizontally rotatably provided in the horizontal groove 16, and a sleeve block 20 threadedly connected to the threaded rod 19. The output end of the drive motor 18 passes through the rectangular groove 17 and is connected to the end of the threaded rod 19. The top of the sleeve block 20 is fixedly connected to the bottom of the support plate 4. The drive motor 18 drives the threaded rod 19 to rotate. The sleeve block 20 moves horizontally along the horizontal groove 16 due to the threaded transmission, thereby driving the support plate 4 and all the components above it to move as a whole, realizing the adjustment of the horizontal position of the transmitting coil 2.
[0023] like Figure 1-4As shown, two sets of side support plates 21 are symmetrically arranged on the top of the support plate 4. The left and right adjustment assembly 5 includes a reciprocating cylinder 22 horizontally fixed on one of the side support plates 21. The piston end of the reciprocating cylinder 22 is fixed to the side of the support box 6. Two sets of limiting rods 23 parallel to the reciprocating cylinder 22 are symmetrically arranged between the two sets of side support plates 21. The two sets of limiting rods 23 are located on both sides of the reciprocating cylinder 22. The support box 6 is slidably mounted on the limiting rods 23. The limiting rods 23 restrict the movement direction of the support box 6 to avoid deviation and ensure the straightness and stability of the lateral fine adjustment. The piston end of the reciprocating cylinder 22 performs telescopic movement, driving the support box 6 to slide laterally along the limiting rods 23 (perpendicular to the movement direction of the threaded rod 19), thereby realizing the longitudinal adjustment of the position of the transmitting coil 2.
[0024] like Figure 1-4 As shown, a horizontally mounted telescopic cylinder 24 is hinged to the top of the top plate 14. The piston end of the telescopic cylinder 24 is hinged to the outer wall of the rotating disk 15. When the piston of the telescopic cylinder 24 extends or retracts, it pushes the rotating disk 15 to rotate around the central axis of the top plate 14 by a certain angle, thereby changing the tilt direction of the transmitting coil 2, adjusting the orientation of the transmitting surface, and adapting to the angle deviation when the vehicle is parked.
[0025] In practical use, first place the device in a suitable position, turn on the drive motor 18 to rotate the threaded rod 19, causing the sleeve block 20 to move horizontally along the transverse groove 16, adjusting the transmitting coil 2 to the approximate lateral position of the vehicle; then start the reciprocating cylinder 22, the piston extension drives the support box 6 to slide laterally along the limit rod 23, making a fine adjustment in the longitudinal position; subsequently, according to the vehicle chassis height, start the rotary motor 9 to rotate the bidirectional lead screw 10, causing the first lead screw pair 12 and the second lead screw pair 13 to move towards or away from each other, pushing the top plate 14 up and down through the connecting rod 11, adjusting the transmitting coil 2 to a suitable height; finally, if there is a parking angle deviation of the vehicle, start the telescopic cylinder 24, its piston end extends and retracts, pushing the rotating disk 15 to rotate around the central axis of the top plate 14, adjusting the tilt direction of the transmitting coil 2; at this point, the transmitting coil 2 has completed all-round precise adjustment in lateral, longitudinal, height and angle, and wireless charging can begin.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
