When the first concave guide surface 231 and the second concave guide surface 232 are worn seriously, the male processing block 28 and the female processing block 26 can relatively rotate, the clamping block 273 rotates to one end port of the communicating groove 252, the inserting block is pulled outwards, the clamping block 273 can be pulled out along the communicating groove 252, and accordingly separation of the inserting block and the sleeve 25 is achieved, and detachment and replacement of the severely worn male processing block 28 and female processing block 26 are facilitated. To facilitate the relative rotation of the male tooling block 28 and the female tooling block 26, anti-slip patterns 29 are provided on the peripheral side walls of the male tooling block 28 and the female tooling block 26.
Referring to fig. 6 and 7, in order to reduce the situation that the clamping block 273 rotates to the port at one end of the communicating groove 252 to cause the plugging block to separate from the sleeve 25 in the use process, a placing groove 241 is formed in the hole wall of the mounting hole 24, a second elastic piece 242 is mounted in the placing groove 241, one end of the second elastic piece 242 is fixed with the bottom wall of the placing groove 241, the other end is fixedly connected with a limiting rod 243, a limiting groove 253 for inserting the limiting rod 243 is formed in the sleeve 25, the limiting groove 253 is communicated with the communicating groove 252, and one end of the limiting rod 243 far away from the second elastic piece 242 extends into the communicating groove 252. One end of the limiting rod 243 close to the female processing block 26 is flush with the inner wall of one side of the clamping groove 251 close to the male processing block 28, one end of the limiting rod 243 close to the bottom wall of the mounting groove 13 is fixedly connected with a pull rod 244, one end of the pull rod 244 away from the limiting rod 243 penetrates out of the limiting plate 23 from the bottom wall of the placing groove 241, and one end of the pull rod 244 penetrating out of the limiting plate 23 is fixedly connected with a pull ball 2441. In this embodiment, the second elastic member 242 is a compression spring.
When the male processing block 28 and the female processing block 26 are disassembled, the pull ball 2441 is pulled, the pull ball 2441 drives the pull rod 244 to move, the pull rod 244 moves to drive the limit rod 243 to move towards the bottom wall of the placing groove 241, the second elastic piece 242 is compressed, the limit plate 23 gradually retracts into the placing groove 241 from the communicating groove 252, at the moment, one end of the communicating groove 252, which is close to the clamping groove 251, is in an open state, and the clamping block 273 can conveniently enter the communicating groove 252 from one end of the communicating groove 252, which is close to the clamping groove 251, when the clamping block 273 rotates. When the new male processing block 28 and the new female processing block 26 are replaced, the pull ball 2441 is loosened, the second elastic piece 242 is reset, the limiting rod 243 is ejected, one end of the limiting rod 243 far away from the bottom wall of the placing groove 241 stretches into one end of the communicating groove 252 close to the clamping groove 251, at this time, one end of the communicating groove 252 close to the clamping groove 251 is in a blocking state, and the situation that the clamping block 273 rotates to one end port of the communicating groove 252 in the use process so that the plugging block is separated from the sleeve 25 is reduced.
The implementation principle of the floating type power conversion plug interface of the automobile battery provided by the embodiment of the application is as follows: when inserting the plug into socket interface 21, through the setting of floating casing 2, floating casing 2 can carry out front and back and all around orientation and float to drive socket interface 21 and carry out the activity around and all around orientation, and then realize the position adjustment of socket interface 21, thereby adapt to the deviation that produces because of not centering, make socket interface 21 adapt to different plugs, reduce the degree of difficulty of inserting, improved the smoothness when plug and socket interface 21 are to the plug.
When the return spring 41 is in a free state, the return spring 41 abuts against the moving plate 42, so that the first ball 421 on the moving plate 42 abuts against the concave center of the first guiding concave 231, and the floating housing 2 is centered; when the floating housing 2 floats around, the floating housing 2 drives the first concave guide surface 231 to move around, the concave center of the first concave guide surface 231 deviates from the position, and during the deviation, the first concave guide surface 231 presses the first ball 421 backwards, so as to drive the moving plate 42 to move towards the rear side of the outer housing 1, and the return spring 41 is compressed; after the plug is pulled out, the reset spring 41 drives the movable plate 42 to reset, the movable plate 42 resets to drive the first ball 421 to reset, the first ball 421 abuts against the first concave guide surface 231, and the first ball 421 drives the floating shell 2 to realize automatic reset and centering through the guiding function of the first concave guide surface 231 so as to prepare for next opposite insertion.
In addition, the return spring 41 also has a damping and buffering function, and when the electric vehicle is in motion, the connection between the socket interface 21 and the corresponding plug has a tendency of shaking or relative displacement caused by vibration from different directions or other uncertain factors, and the shaking can be buffered through the return spring 41, so that the possibility of damage to the plug and the socket interface 21 caused by long-time impact vibration is reduced.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
