[0018] In this embodiment, a door lock assembly 4 adapted to the lock assembly 2 is provided on the external vehicle door, and the buffer member 3 can play a buffering role during the insertion of the door lock assembly 4 into the lock assembly 2. Specifically, The door lock assembly 4 includes a door lock support shell 41 and a door lock structure 42 for locking or unlocking the door lock connected to the lock post 23. One end of the door lock support shell 41 is provided with a lock tongue 411, and the lock tongue 411 can be inserted into the buffer groove 24. The door lock structure 42 includes a vehicle door lock body 421, a lock body paddle 422 and an opening arm 423. The door lock support shell 41 is rotatably connected with a first support column 412, a second support column 413 and a third support column 414. The first support column 412 is rotatably connected to a door lock body 421, the second support column 413 is rotatably connected to a lock body paddle 422, and the third support column 414 is rotatably connected to an opening arm 423. The door lock body 421, the lock body paddle 422 and the opening arm 423 are adjacent to each other in a transmission connection. One end of the door lock body 421 is provided with a lock body groove 4211, and the other end is provided with a limit slot 4212. One end of the opening arm 423 is stuck in the limiting slot 4212, one end of the opening arm 423 is provided with a limiting vertical plate 4231, the other end of the lock body paddle 422 is attached to one side of the limiting vertical plate 4231, one end of the door lock support shell 41 is provided with a shell fixing plate 415, and the shell fixing plate 415 is connected to the inside of the door of the farmer's car. When the opening arm 423 rotates, it can drive the lock body paddle 422 to rotate, and when the lock body paddle 422 rotates, it can drive the door lock body 421, and the door lock body During the transmission process between 421, the lock body paddle 422 and the opening arm 423, the first support column 412, the second support column 413 and the third support column 414 play a supporting and guiding role. The rotation of the door lock body 421 makes it lock or disengage from the surface of the lock post 23, thereby realizing the locking process of the farmer's car door. Since the driving conditions of the farmer's car are very bad, without the buffer of the lock tongue 411, the lock post 23 and the door lock body 421 will be seriously deformed.

[0019] Working principle and use method of the present invention: First, the surface area of ​​the lock support seat 22 connected to the lock column 23 is provided with a buffer member 3 so that a buffer area is created between one side of the door of the farmer's vehicle and the lock support seat 22, thereby reducing the friction generated when the door is closed and the vehicle is driving, and playing the role of shock absorption and noise reduction; Secondly, when the door is closed, when the door lock body 421 is inserted into the lock post 23, the lock tongue 411 will be inserted into the buffer groove 24 first, and the buffer 3 will be used for priority buffering. A buffer structure is generated between the door lock body 421 and the lock post 23, which buffers the impact force generated by the door and transmits the force to the vehicle body, which can effectively increase the force-bearing area of ​​the entire lock assembly 2; Furthermore, the setting of the buffer member 3 can provide a certain support to one side of the door, thereby protecting the door lock body 421, increasing the service life of the door lock body 421 and the lock post 23, and effectively preventing the occurrence of intentional accidents, thereby improving the user experience; Finally, since the door lock assembly 4 has a built-in lock tongue 411 for buffering, the lock tongue 411 is automatically inserted into the buffer groove 24 during the door closing process, forming a contact surface that is locked up and down to prevent up and down movement, which not only ensures the switching coordination between the door lock body 421 and the lock post 23 but also reduces the wear itself. At the same time, it prevents the risk of the door hanging down during vehicle vibration and bumps, greatly improving the service life of the door lock body 421 and the lock post 23; the structure is simple and reliable, and it is easy to use.
