Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of charging port structure for new energy vehicles, and specifically to a novel IP67-rated electronic lock for a charging gun. Background Technology
[0002] With the rapid development of the new energy vehicle industry, electric vehicles are powered by battery packs, making charging a crucial issue. Currently, DC charging guns on the market typically require electronic locks and lock / unlock signal feedback devices to ensure charging reliability and safety. The electronic lock ensures the charging gun plugs don't fall out during charging, and the lock / unlock signal feedback device effectively relays the vehicle's electronic lock status. However, the electronic lock and signal feedback device are usually independently located within the charging gun, so the information from the electronic lock and signal feedback cannot synchronously and accurately display the charging gun's operating status. This also hinders the charging gun's waterproofing and dustproofing, and the manufacturing process is cumbersome and costly. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model aims to provide a novel IP67-rated electronic lock for charging guns. By integrating a micro switch (signal feedback) into the electronic lock through a transmission structure design, the structure is simple and ingenious, requires low manufacturing process, has stable performance, and results in a smaller electronic lock size, while also reducing production costs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A novel IP67-rated electronic lock for a charging gun includes a housing consisting of an upper housing and a lower housing, and a rotating motor disposed within the housing. A gear is mounted on the shaft of the rotating motor. The lock also includes a reduction gear set, a micro switch, and a locking block. One end of the reduction gear set meshes with the gear, and the other end connects to the locking block. An inner housing is also provided, in which the rotating motor and the reduction gear set are housed. The drive shaft of the reduction gear set extends out of the inner housing. A fixing post is located on one side of the inner housing, and a recessed hole corresponding to the fixing post is located on one side of the micro switch. The locking block has a locking surface, and the upper housing has a hollowed-out portion corresponding to the locking surface. When a signal feedback is generated, the locking block and the micro switch abut against each other.
[0006] It should be noted that the locking block is also provided with a boss and a slot, and the inner surface of the lower housing is provided with a limiting block; when locked, the slot and the protruding rib abut against each other; when a signal feedback is generated, the boss and the micro switch abut against each other.
[0007] It should be noted that the micro switch is a spring switch, and when a signal feedback is generated, the boss and the spring abut together.
[0008] It should be noted that the drive shaft is connected to the lock block.
[0009] It should be noted that a sealing gasket and a sealing ring are sequentially provided on the inner side of the drive shaft extending out of the inner shell.
[0010] The beneficial effects of this utility model are that it integrates signal feedback with the electronic lock using a transmission structure. The drive motor is connected to a positive and negative pulse power supply, and the rotation of the drive motor output shaft drives the gear to rotate, triggering a micro switch, thus stably and effectively integrating signal feedback into the electronic lock. Simultaneously, the electronic lock motor assembly is sealed with a plastic shell using a liquid silicone sealing process, and the entire outer shell is secured using a snap-fit structure.

[0016] The present invention will be further described below with reference to the accompanying drawings. It should be noted that the following embodiments are based on the present technical solution and provide detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to these embodiments.
[0017] like Figures 1 to 5As shown, this utility model is a novel IP67-rated electronic lock for a charging gun, comprising a housing consisting of an upper housing 1 and a lower housing 2, and a rotating motor 3 disposed within the housing. A gear is mounted on the shaft of the rotating motor 3. A reduction gear set, a micro switch 4, and a locking block 5 are provided. One end of the reduction gear set meshes with the gear, and the other end is connected to the locking block 5. Furthermore, this utility model also includes an inner housing 6, in which the rotating motor 3 and the reduction gear set are disposed. The drive shaft 7 of the reduction gear set extends out of the inner housing 6. A fixing post 61 is provided on one side of the inner housing 6, and a recessed hole corresponding to the position of the fixing post 61 is provided on one side of the micro switch 4. The locking block 5 has a locking surface 51, and the upper housing 1 has a hollow portion 11 corresponding to the position of the locking surface 51. When a signal feedback is generated, the locking block 5 and the micro switch 4 abut against each other.
[0018] Furthermore, the locking block 5 of this utility model is also provided with a boss 52 and a slot 53, and a limiting block is provided on the inner surface of the lower housing 2; when locked, the slot 53 and the protruding rib abut against each other; when a signal feedback is generated, the boss 52 and the micro switch 4 abut against each other.
[0019] Furthermore, the micro switch of this invention is a spring switch, and when a signal feedback is generated, the boss and the spring abut against each other.
[0020] Furthermore, the transmission shaft 7 of this utility model is connected to the locking block 5.
[0021] Furthermore, the drive shaft 7 of this utility model extends out of the inner shell 6 and is provided with a sealing gasket 8 and a sealing ring 9 in sequence.
[0022] Example
[0023] When locking is activated, the rotating motor rotates, which in turn rotates the drive shaft through the reduction gear set. The locking block rotates synchronously, and when the locking block's slot rotates to the position of the protruding rib on the lower housing, it locks. The locking surface of the locking block is exposed in the hollow part of the upper housing. At the same time, the protrusion of the locking block touches the micro switch to trigger a feedback signal, and finally the locking gun is completed.
[0024] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
