Description

Technical Field

[0001] The present invention relates to the field of vehicle charging ports, and in particular to a charging port locking mechanism and a charging port assembly having the charging port locking mechanism. Background Art

[0002] Faced with the increasingly serious global environmental crisis and energy depletion, vigorously developing new energy has been elevated to a strategic position for countries around the world.

[0003] Compared with traditional cars, new energy electric vehicles have the advantages of no exhaust emissions, low energy consumption, low noise, and safety. They are increasingly valued and are gradually becoming a trend in automobile development.

[0004] Existing electric vehicles are generally provided with a charging port, and the charging port is usually arranged in a charging port cover assembly.

[0005] The charging port cover at the rear of the electric vehicle's side is an important component that covers the electric vehicle's charging port. When charging starts, the charging port cover is opened to the maximum opening state to allow the charging gun to enter for charging. After charging is completed, the charging gun is pulled out and the charging port cover is closed, which serves as a decoration and seal.

[0006] In the prior art, there are two main ways to open the charging port cover of an electric vehicle. The first way is to overlap the charging port cover and the front bumper assembly, and open the charging port cover by pulling a zipper inside the cabin.

[0007] However, since the charging port cover is restricted by its movement trajectory when opened, the charging port cover and the front guard assembly are overlapped, resulting in the shape here protruding outward more, which makes it easy for external objects to interfere, poses a safety risk, and has poor sealing.

[0008] The second type is that the charging port cover is connected to the side panel and uses a PUSH-PUSH opening method to open and close the charging port cover. However, this type of charging port cover is opened and closed manually. This structure is complicated for the owner to operate, the opening force is large, the speed is fast and uncontrollable, and the perception is not good. This results in a poor user experience and there is also a defect of poor sealing.

[0066] In addition, the present invention not only facilitates the installation and arrangement of the transmission mechanism 6 through the provision of the cam plate 5, but also facilitates the synchronous driving of the transmission mechanism 6 and the charging port locking mechanism by using one driving end.

[0074] The charging port assembly disclosed in the present invention can realize that the charging port cover 1 is automatically opened to the maximum position without manual pressing of the cover to open it, thereby simplifying the charging action, and the opening process is slow and uniform, with better visual perception.

[0075] The charging port cover 1 automatically opens to the maximum position without manual pressing of the cover to open it, thus simplifying the charging action.

[0076] The opening process is slow and uniform, which provides better visual perception and enhances user experience.

[0077] The charging port cover 1 is stable when opened to the maximum and closed without shaking.

[0078] In the present invention, the driving mechanism 3 is arranged on the pin shaft side, providing a power source for opening and closing the charging port cover 1; a pair of gear sets and camshaft transmission are used to output the actuator motor torque to the pin shaft 8 of the charging port box 2, driving the hinge plate 4 and the charging port cover 1 to rotate and open.

[0079] A proximal lock is designed to utilize the cam plate 5 to drive the locking rod 7 to lock the hinge, thereby ensuring that the charging port cover 1 does not shake.

[0080] Specific working principle:

[0081] The charging port cover 1 is assembled on the hinge plate 4. After the hinge plate 4 receives the opening and closing instruction, the charging port cover 1 is opened and closed in association with the hinge plate 4;

[0082] Opening method: The vehicle control module transmits the opening signal to the actuator through the harness assembly 9. After the actuator receives the opening signal, the motor drives the cam plate 5 to rotate. After the cam plate 5 drives the linkage block 71 to run for a certain distance, the lock rod 7 is controlled to withdraw from the charging port box 2. The charging port assembly is unlocked, and the cam plate 5 continues to rotate, driving the transmission mechanism 6 to rotate. The transmission mechanism 6 drives the pin shaft 8 to rotate. The pin shaft 8 drives the hinge plate 4 to rotate to the maximum opening angle, thereby realizing the opening of the charging port cover 1.

[0083] Closing method: The vehicle control module transmits the closing signal to the actuator through the wiring harness assembly 9. After the actuator receives the closing signal, the motor drives the cam plate 5 to rotate, the cam plate 5 drives the transmission mechanism 6 to rotate, the transmission mechanism 6 drives the pin shaft 8 to rotate, and the pin shaft 8 drives the hinge plate 4 to rotate to the closed position. After the charging port cover 1 is closed, the actuator drives the cam plate 5 to continue to rotate, and after driving the linkage block 71 for a stroke, the locking rod 7 extends and is inserted into the charging port box 2, thereby realizing the locking operation of the charging port assembly.

[0084] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
