Technical Field

[0001] This utility model belongs to the field of wireless charging technology, specifically relating to a wireless precision charging device for electric vehicles. Background Technology

[0002] As environmental pollution from gasoline-powered vehicles becomes increasingly prominent, and with the growing scarcity of oil resources, countries around the world are actively developing and promoting new energy vehicles. This has led to a recovery in the new energy vehicle industry, with the number of new energy vehicles on the market steadily increasing year by year. However, the development of new energy vehicles faces challenges. On the one hand, their top speed cannot match that of gasoline-powered vehicles, and their limited range can cause driver anxiety, weakening their market competitiveness.

[0003] Currently, traditional electric vehicles primarily rely on wired charging stations installed in parking spaces for charging. However, this charging method has several drawbacks. On one hand, new energy vehicles themselves have performance limitations; their top speed is lower than that of traditional gasoline vehicles, and their driving range is limited, often causing driver anxiety and significantly weakening their market competitiveness. On the other hand, the charging method itself is a major obstacle. Traditional electric vehicles mostly rely on wired charging stations in parking spaces, which are cumbersome for owners to operate. Careless plugging and unplugging can easily cause the wires to come loose, interrupting charging and reducing efficiency. Moreover, public charging stations are frequently vandalized and stolen, causing inconvenience for owners and seriously hindering the popularization and development of new energy vehicles. Therefore, an improved technical solution is needed to address the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems of traditional wired charging methods for electric vehicles, such as cumbersome operation, low charging efficiency, and susceptibility to malicious damage or theft of charging equipment, and to provide a wireless precision charging device for electric vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wireless precision charging device for electric vehicles includes: a wireless charging transmitter, a pressure plate, and a guide plate. The wireless charging transmitter is located in the center of a parking platform and is flush with the upper surface of the parking platform. The pressure plate is hinged to the front end of the upper surface of the parking platform, so that the end of the pressure plate away from the wireless charging transmitter is raised to form a downward pressure space with the parking platform. When the pressure plate bears the weight of the electric vehicle, the pressure can be transmitted to the underside of the wireless charging transmitter through a linkage mechanism, so as to lift the wireless charging transmitter vertically upward and align it with the wireless charging receiver at the bottom of the electric vehicle. A pair of guide plates are provided and are respectively hinged to both sides of the pressure plate. The two guide plates correspond to the two wheels of the electric vehicle, and a portion of the guide plates rests on the upper surface of the parking platform.

[0007] In one possible implementation of the wireless precision charging device for electric vehicles described above, the front end of the raised face of the parking platform is provided with a groove that matches the pressure plate, so that the pressure plate is pressed down to be flush with the upper surface of the parking platform.

[0008] In one possible implementation, the upper surface of the pressure plate is provided with a protruding ridge along the width direction of the parking platform.

[0009] In one possible implementation, the guide plate surface is provided with anti-slip textured surfaces.

[0010] In one possible implementation, the linkage mechanism includes: a guide unit, a reset unit, a transmission arm, and a top support arm, and the parking platform has a cavity inside that accommodates the wireless charging transmitter and the linkage mechanism.

[0011] The guiding unit includes a guide post and a sleeve. The guide post is erected inside the cavity, and the sleeve is fitted over the outside of the guide post. The upper end of the sleeve is aligned with and centered on the bottom of the wireless charging transmitter.

[0012] In one possible implementation, the guide post surface is provided with a guide channel along the axial direction, a lifting rod is inserted transversely into the guide channel, and the end of the lifting rod penetrates the sleeve wall and protrudes outward;

[0013] The length direction of the lifting arm is consistent with the width direction of the parking platform.

[0014] In one possible implementation, the reset unit includes: a positioning post, a pressure tube, and a reset spring, wherein the positioning post is horizontally disposed within the cavity and located on one side of the guide post;

[0015] One end of the positioning post is connected to the inner wall of the cavity, and the other end is supported by the positioning plate;

[0016] Both the pressure tube and the return spring are sleeved on the outside of the positioning post, so that the pressure tube squeezes the return spring when it slides along the axial direction of the positioning post.

[0017] In one possible implementation, the transmission arm is obliquely disposed within the cavity;

[0018] The high end of the transmission arm extends out of the cavity and is hinged to the lower surface of the raised end of the pressure plate, while the low end is hinged to the top of the pressure tube.

[0019] In one possible implementation, the top support arm is obliquely disposed within the cavity;

[0020] The upper end of the top support arm is sleeved on the outside of the lifting rod, and the lower end is hinged to the top of the pressure tube and also to the transmission arm.

[0021] In one possible implementation, the transmission arm and the top support arm form a triangular angle.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] This invention provides a favorable charging environment for electric vehicles by using wireless charging. The charging process is simple, there is no risk of disconnection, and the charging efficiency is effectively improved. It also prevents the charging equipment from being maliciously damaged or stolen, making it safe and effective to use. Attached Figure Description

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0035] This embodiment aims to provide a wireless precision charging device for electric vehicles. Its main function is to charge electric vehicles wirelessly, which is simple, convenient and efficient, while avoiding malicious damage or theft of the charging equipment.

[0036] Reference Figures 1-6 The wireless precision charging device for electric vehicles includes: a wireless charging transmitter 1, a pressure plate 3, and a guide plate 4. The wireless charging transmitter 1 is located in the center of the parking platform 2 and is flush with the upper surface of the parking platform 2. The front end of the upper surface of the parking platform 2 is provided with a groove 5 that matches the pressure plate 3. The rear end of the pressure plate 3 is correspondingly hinged in the groove 5. The front end of the pressure plate 3, that is, the end away from the wireless charging transmitter 1, is raised to form a downward pressing space with the parking platform 2. The groove 5 allows the pressure plate 3 to be pressed down to be flush with the upper surface of the parking platform 2.

[0037] When the pressure plate 3 bears the weight of the electric vehicle, the pressure can be transmitted to the bottom of the wireless charging transmitter 1 through the linkage mechanism, so as to lift the wireless charging transmitter 1 vertically upward and make it coincide with the wireless charging receiver at the bottom of the electric vehicle. Specifically, the parking platform 2 is provided with a cavity 9 that accommodates the wireless charging transmitter 1 and the linkage mechanism. The linkage mechanism can be symmetrically arranged in two sets in the cavity 9 to ensure the stability of the structure.

[0038] The linkage mechanism includes a guide unit, a reset unit, a transmission arm 7, and a top support arm 8. The guide unit includes a guide post 10 and a sleeve 11. The guide post 10 is vertically fixed in the cavity 9. The sleeve 11 is sleeved on the outside of the guide post 10, and the upper end of the sleeve 11 is fixedly connected to the bottom of the wireless charging transmitter 1 and centered. The guide post 10 has a guide channel 12 along the axial direction. In order to accommodate the two sets of linkage mechanisms, the guide channel 12 must pass through the guide post 10 in the transverse direction. A lifting rod 13 is horizontally inserted in the guide channel 12, and the end of the lifting rod 13 passes through the cylinder wall of the sleeve 11 and protrudes outward to connect to the top support arm 8. The length direction of the lifting rod 13 is consistent with the width direction of the parking platform 2.

[0039] The reset unit includes a positioning post 14, a pressure tube 15, and a reset spring 16. The positioning post 14 is horizontally disposed within the cavity 9 and located on one side of the guide post 10. The axial direction of the positioning post 14 is aligned with the length direction of the parking platform 2, so that one end of the positioning post 14 is fixedly connected to the inner wall of the cavity 9, and the other end is fixedly supported by the positioning plate 17. The pressure tube 15 and the reset spring 16 are both sleeved on the outside of the positioning post 14. The pressure tube 15 is located at the front end of the positioning post 14, so that when the pressure tube 15 slides backward along the axial direction of the positioning post 14, it can achieve the reset function. The return spring 16 is compressed, the transmission arm 7 is obliquely arranged in the cavity 9, the high end of the transmission arm 7 extends out of the cavity 9 and is hinged to the lower end of the pressure plate 3, the low end of the transmission arm 7 is tilted backward and is hinged to the top of the pressure tube 15, the top support arm 8 is obliquely arranged in the cavity 9, the high end of the top support arm 8 is correspondingly sleeved on the outside of the lifting rod 13, the low end of the top support arm 8 is tilted forward and is hinged to the top of the pressure tube 15 and also to the transmission arm 7. The two share a hinge axis, thus, a triangular angle is formed between the transmission arm 7 and the top support arm 8.

[0040] In this embodiment, the upper surface of the pressure plate 3 is provided with a protruding rib 6 along the width direction of the parking platform 2. When the front tire of the electric vehicle passes over the protruding rib 6, a slight bump will occur, thereby providing feedback to the driver and proving that the wireless charging transmitter 1 has corresponded and overlapped with the wireless charging receiver at the bottom of the electric vehicle, thus improving accuracy.

[0041] In this embodiment, a pair of guide plates 4 are provided, and the two guide plates 4 are respectively hinged to the left and right sides of the pressure plate 3. The two guide plates 4 correspond to the two wheels of the electric vehicle. If necessary, notches can be opened on the left and right sides of the pressure plate 3 to calibrate the position of the guide plates 4 and the two wheels of the electric vehicle. Based on this, the accurate correspondence between the wireless charging transmitter 1 and the wireless charging receiver at the bottom of the electric vehicle can be greatly improved, ensuring the charging quality. In this embodiment, a part of the guide plates 4, that is, the rear end of the guide plates 4, is placed on the upper surface of the parking platform 2 so that the rear end of the guide plates 4 is supported by the parking platform 2.

[0042] In this embodiment, the surface of the guide plate 4 is provided with anti-slip ridges. Since the guide plate 4 is connected to the pressure plate 3, it has a certain degree of inclination. By setting anti-slip ridges on its surface, the electric vehicle can be made to move stably.

[0043] In use, align the electric vehicle with the guide plates 4 on both sides of the pressure plate 3, and then move forward. When the front tires of the vehicle walk onto the guide plates 4 and continue moving forward, the raised end of the pressure plate 3 will gradually descend and squeeze the high end of the transmission arm 7, causing the low end of the transmission arm 7 to push the pressure tube 15. When the pressure tube 15 moves, it will push the low end of the top support arm 8 and squeeze the return spring 16, so that the top support arm 8 can vertically lift the sleeve 11 and the wireless charging transmitter 1 upward along the guide post 10. The function of the return spring 16 is to provide a reverse force to the transmission arm 7 so that the wireless charging transmitter 1 can be reset. When the front tires of the electric vehicle pass over the protrusion 6 on the pressure plate 3 and the driver feels a bump, the vehicle can stop. At this time, it can be confirmed that the wireless charging transmitter 1 has aligned with the wireless charging receiver at the bottom of the electric vehicle and can be charged.

[0044] This embodiment uses wireless charging to provide a favorable charging environment for electric vehicles. The charging process is simple, there is no risk of disconnection, and the charging efficiency is effectively improved. It also prevents the charging equipment from being maliciously damaged or stolen, making it safe and effective to use.

[0045] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
