Technical Field

[0001] This invention relates to the field of farmer's vehicle technology, specifically to a farmer's vehicle door lock and the vehicle thereof. Background Technology

[0002] UTV, short for Utility Terrain Vehicle, is a type of vehicle designed for traversing various complex terrains. UTVs typically possess high off-road capabilities, making them suitable for use in environments such as mines, wilderness, beaches, and mountains. Farmer vehicles often operate in harsh environments, frequently encountering mud, water crossings, gravel roads, deserts, and hillsides, resulting in significant vibration and bumps. This places high demands on the door locks and other components. The high frequency of door opening and closing, coupled with the intense vibration and bumps, directly impacts the customer's experience and subjective impression.

[0003] Authorization announcement number CN215369274U discloses a protective cover for a car door lock latch. According to its instruction manual and drawings, it includes a cover body; a side plate integrated with the cover body; a protective layer tightly fitted to the inner side of the side plate; and a raised cap on the cover body. The upper surface of the cap has a protective structure to solve the problem of damaging the car paint when closing the door. However, there is still a wear problem in the door latch and door lock body opening and closing mechanism, which may lead to the risk of failure of the door lock body and door latch. Summary of the Invention

[0004] This invention addresses the problems encountered when using a farmer's vehicle by providing a farmer's vehicle door lock and the vehicle itself. The surface area of ​​the lock support base incorporates a buffer element, creating a buffer zone between the farmer's vehicle door and the lock support base, thereby reducing friction during door closing and vehicle movement. During door closing, when the door lock body inserts into the lock post, the latch preferentially inserts into the buffer groove. The buffer element's surface provides initial cushioning, and another buffer structure is created between the door lock body and the lock post, buffering the impact force generated by the door and transferring the force to the vehicle body. Since the door lock assembly has a built-in latch for cushioning, the latch automatically inserts into the buffer groove during closing, creating a locked contact surface to prevent vertical movement. The buffer element provides support to one side of the door after it is closed, thus protecting the door lock body.

[0005] The objective of this invention is achieved through the following technical solution: a farmer's vehicle door lock, comprising a vehicle frame body, a lock assembly on one side of the vehicle frame body, a buffer member on the lock assembly, and a door lock assembly adapted to the lock assembly on the outer door, wherein the buffer member can play a buffering role during the process of the door lock assembly being inserted into the lock assembly.

The end of the locking post 23 is provided with a limiting ring groove 231 adapted to the first through holes 221. The surface of the buffer member 3 is provided with several second through holes 31 coaxial with the first through holes 221. The limiting ring groove 231 passes through the second through holes 31 and is locked inside the first through holes 221. That is, the limiting ring groove 231 passes through the buffer member 3 and is locked inside the first through holes 221. The buffer member 3, the locking fixing seat 21 and the locking support are all located on the other side of the frame support plate 11. The support base 22 has a buffer groove 24 in the middle. The buffer member 3 can cover the entire latch support base 22. The buffer groove 24 is designed to buffer the insertion of the external latch tongue 411. The surface of the latch fixing base 21 is also provided with several third through holes 211. The surface of the buffer member 3 is provided with several fourth through holes 32 coaxial with the third through holes 211. The interior of the third through holes 211 and the fourth through holes 32 is provided with screw support sleeves 5. A screw fixing block 6 is provided on one side of the latch fixing base 21. The interior of component 5 is provided with a fixing screw 7 that passes through the frame support plate 11 and connects to the buckle fixing seat 21 and the screw fixing block 6. With this setting, the entire buckle assembly 2 can be detachably connected to the frame support plate 11 by using the fixing screw 7. When the fixing screw 7 is inserted into the screw support sleeve 5, the fourth through hole 32, the fifth through hole 222 and the third through hole 211 in sequence, during this connection process, the screw support sleeve 5 and the limiting ring groove pass through the second through hole and are stuck inside the first through hole, which can effectively make the buffer 3 firmly stick to the buckle support seat 22.

[0023] In this embodiment, the outer door is provided with a door lock assembly 4 that is adapted to the latch assembly 2. During the insertion of the door lock assembly 4 into the latch assembly 2, the buffer 3 can play a buffering role. Specifically,

[0024] The door lock assembly 4 includes a door lock support shell 41 and a door lock structure 42 for locking or unlocking, which is engaged with the strike plate 23. One end of the door lock support shell 41 is provided with a latch 411, which can be inserted into the interior of the buffer groove 24. The door lock structure 42 includes a door lock body 421, a lock body lever 422, and an opening arm 423. A first support post 412, a second support post 413, and a third support post 414 are rotatably connected to the door lock support shell 41. 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 lever 422, and the third support column 414 is rotatably connected to an opening arm 423. The door lock body 421, lock body lever 422, and opening arm 423 are connected in a transmission manner to each other.

When the lock body lever 422 rotates, it can drive the door lock body 421. 421. During the transmission process between the lock body lever 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 causes it to lock or disengage from the surface of the latch column 23, thereby realizing the locking process of the farm vehicle door. Since the driving conditions of the farm vehicle are very harsh, if there is no buffer of the latch 411, the latch column 23 and the door lock body 421 will be severely deformed.

[0025] Working principle and usage of this invention:

[0026] First, the surface area of ​​the latch support seat 22 connected to the latch post 23 is provided with a buffer 3 so that a buffer area is created between the side of the farmer's vehicle door and the latch support seat 22, thereby reducing the friction generated when the door is closed and the vehicle is moving, and playing the role of shock absorption and noise reduction.

[0027] Secondly, during the closing process, when the door lock body 421 is inserted into the latch 23, the latch 411 will preferentially insert into the buffer groove 24, and the buffer 3 will provide preferential buffering. A buffer structure is generated between the door lock body 421 and the latch 23, which buffers the impact force generated by the door and transmits the force to the vehicle body, effectively increasing the force-bearing area of ​​the entire latch assembly 2.

[0028] Furthermore, the buffer 3 provides some 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 latch 23, effectively preventing accidental damage, and improving the user experience.

[0029] Finally, since the door lock assembly 4 has a built-in latch 411 for buffering, the latch 411 automatically inserts into the buffer groove 24 during the closing process, creating a locking contact surface to prevent vertical movement. This ensures the opening and closing coordination between the door lock body 421 and the strike plate 23 while reducing wear on itself. It also prevents the door from slipping during vehicle vibration and bumps, greatly improving the service life of the door lock body 421 and the strike plate 23. Moreover, the structure is simple, reliable, and easy to use.
