Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, in the present embodiment: the utility model provides a new energy automobile rifle electronic lock that charges, including motor housing 1, motor housing 1's back fixed mounting has lid 2 behind the motor, the front fixedly connected with motor 3 of lid 2 behind the motor, motor 3's front fixed mounting has "I shape" sealing washer 4, motor housing 1's front fixedly connected with lockpin 5, the top fixedly connected with micro-gap switch 6 of lockpin 5, micro-gap switch 6's side fixed mounting has lower cover 7, the front fixed mounting of lockpin 5 has upper cover to constitute 8.

In the embodiment, a motor 3 inside the electronic lock is connected to a positive and negative pulse power supply, the motor 3 rotates out of a shaft to drive a lock pin 5 to rotate, when the lock pin 5 rotates to a proper angle, the lock pin 5 is locked, and meanwhile, the lock pin 5 touches a micro switch 6 and the electronic lock is locked by a signal feedback trigger. The electronic lock motor 3 assembly is sealed by a plastic shell, an output shaft of the motor 3 is protected by an I-shaped sealing ring 4, the tail output wire end point is sealed by liquid silica gel, and the upper cover 7 and the lower cover 7 are installed and matched by using an ultrasonic welding technology. Lockpin 5 is installed on 3 output shafts of motor 3 subassembly, and micro-gap switch 6 is installed on 3 subassembly motor housing 1 of motor, and lockpin 5 during operation triggers micro-gap switch 6, and both cooperations form electronic lock signal feedback subassembly. The electronic lock signal feedback assembly is embedded in the lower cover 7. The motor 3 assembly, the electronic lock signal feedback assembly and the lock pin 5 assembly are sequentially arranged in the lower cover 7, the upper cover is covered, all cables are led out from a wire slot hole at the tail part of the shell, and finally the upper cover 7 and the lower cover 7 are welded by an ultrasonic welding machine to realize product packaging. The I-shaped sealing ring 4 is arranged in a circular hole of the motor shell 1, the motor 3 is arranged in the motor shell 1, and the motor rear cover 2 is covered; and finally, liquid silica gel is injected at the end of the motor rear cover 2 for curing and sealing.

The working principle and the using process of the utility model are as follows: the I-shaped sealing ring 4 is arranged in a round hole of the motor shell 1, the motor 3 is arranged in the motor shell 1, an output shaft of the motor 3 penetrates out of the I-shaped sealing ring 4, the motor rear cover 2 is covered, and glue dispensing, curing and sealing are carried out to form a motor 3 assembly. The core control assembly completes the waterproof and dustproof functions in this way, and the microswitch 6 is installed and fixed on two positioning columns A at the upper part of the motor shell 1; then the lock pin 5 is arranged and sleeved on the output shaft of the motor 3 assembly. When applying operating voltage for 3 subassemblies of motor, thereby 3 play rotations of motor drive lockpin 5 rotatoryly, 5 convex surfaces B of lockpin touch micro-gap switch 6's wane triggers electronic lock signal feedback immediately, just so forms signal feedback subassembly.
