[0040] With the continuous innovation of automobile design concepts, the continuous application of new technologies, and the continuous optimization and development of production processes, the automobile industry has developed rapidly. In addition to the traditional functions, performance and safety of automobiles, people have also put forward higher requirements for the convenience of vehicle-related operations. Among them, when locking the door, the lock buckle and the lock body switch need to cooperate, and when the door is closed, there will be an impact, which may cause the lock body and the door lock buckle to deform or wear, thereby reducing the locking reliability between the door lock body and the lock buckle.

[0041] See also Figures 1 to 7 In one embodiment of the present application, the vehicle door lock structure 100 includes a lock 2 and a buffer block 3, the lock 2 is used to connect with the first vehicle door 400; the lock 2 is used to buckle with the lock body 200 on the vehicle body 300 or another vehicle door; the buffer block 3 is used to connect with the first vehicle door 400; the buffer block 3 is provided with a first abutting surface 31 and a second abutting surface 32, and the first abutting surface 31 and the second abutting surface 32 intersect; the first abutting surface 31 is used to abut with a side surface of the lock body 200 facing the lock 2, and the second abutting surface 32 is used to abut with a side surface of the lock body 200 facing the interior of the vehicle compartment.

[0042] In the above structure, the lock buckle 2 and the buffer block 3 are connected to the first vehicle door 400, wherein the buffer block 3 is located next to the lock buckle 2, and the buffer block 3 is provided with a first abutting surface 31 and a second abutting surface 32, and the first abutting surface 31 and the second abutting surface 32 intersect; when the lock buckle 2 is buckled with the lock body 200 of the vehicle body 300, the first abutting surface 31 of the buffer block 3 abuts against the side surface of the lock body 200 facing the lock buckle 2, and the second abutting surface 32 of the buffer block 3 abuts against the side surface of the lock body 200 facing the inside; therefore, during the closing process of the first vehicle door 400, the first abutting surface 31 of the buffer block 3 abuts against the first vehicle door, so that the buffer block 3 buffers the impact force generated by the first vehicle door 400, which can reduce the lock body 200 and The lock buckle 2 is deformed, which improves the locking stability of the lock body 200 and the lock buckle 2; and because the first abutting surface 31 abuts against the surface of the side of the lock body 200 facing the lock buckle 2, and the second abutting surface 32 abuts against the side of the lock body 200 facing the interior of the vehicle, the first abutting surface 31 and the second abutting surface 32 of the buffer block 3 can provide a limiting effect between the door lock buckle structure 100 and the lock body 200, thereby further improving the locking stability of the lock body 200 and the lock buckle 2; the buffer block 3 added to the door lock buckle structure 100 can have both buffering and limiting effects, thereby reducing the number of limiting parts required, reducing the overall volume of the door lock buckle structure 100, and reducing the overall layout space required for the door lock buckle structure 100.

[0043] Exemplarily, the lock body 200 is connected to the vehicle body 300, and an installation cavity is provided on the vehicle body 300. The lock body 200 is arranged in the installation cavity. When the lock body 200 is buckled with the lock buckle 1, the buffer block 3 is located in the installation cavity, and the first abutting surface 31 of the buffer block 3 abuts against the side surface of the lock body 200 facing the lock buckle 1, and the second abutting surface 32 of the buffer block 3 abuts against the side surface of the lock body 200 facing away from the interior of the vehicle.

[0044] In one embodiment, reference Figure 1The buffer block 3 is provided with a first extension portion 33 and a second extension portion 34, the extension direction of the first extension portion 33 intersects with the extension direction of the second extension portion 34, the first abutting surface 31 is provided on the first extension portion 33, and the second abutting surface 32 is provided on the second extension portion 34. When the first vehicle door 400 is closed, the vehicle door lock catch structure 100 and the lock body 200 are buckled, the first abutting surface 31 abuts against the side surface of the lock body 200 facing the lock catch, and the second abutting surface 32 abuts against the side surface of the lock body facing the interior of the vehicle compartment, wherein the buffer block 3 is made of elastic material, and when the first vehicle door is closed, impact vibration is generated, and the buffer block 3 absorbs the vibration by elastic deformation, thereby providing a buffering effect between the lock body 200 and the lock catch 2. Specifically, the extension direction of the first extension portion 33 and the extension direction of the second extension portion 34 are perpendicular to each other, and the buffer block 3 is in a "7" shape, so that the first extension portion 33 of the buffer block 3 abuts against the side surface of the lock body 200 facing the lock buckle 2, and the second extension portion 34 of the buffer block 3 abuts against the side surface of the lock body 200 facing the interior of the vehicle, and the buffer block 3 provides buffering and limiting functions for the lock body 200.

[0045] In one embodiment, the buffer block 3 is made of rubber material. The rubber material has good elasticity and can restore to its original shape when subjected to pressure or impact, so that the buffer block 3 can effectively absorb and disperse the impact force generated by closing the first door 400, and can protect the lock body 200, the first door 400 and other components. And because the rubber material can absorb sound, the noise generated during the closing operation of the first door 400 can be reduced.

[0046] In one embodiment, reference Figure 5 There is a gap 4 between the lock buckle 2 and the buffer block 3. The lock buckle 2 is used to buckle with the lock tongue of the lock body 200. The existence of the gap 4 between the lock buckle 2 and the buffer block 3 provides enough space for the lock buckle 2 to buckle with the lock tongue of the lock body 200.

[0047] In one embodiment, reference Figure 1A first inclined surface 35 is provided at one end of the second extension portion 34 away from the first extension portion 33, and the first inclined surface 35 is connected to the second abutting surface 32; a second inclined surface 36 is also provided at one end of the second extension portion 34 away from the first extension portion 33, and the second inclined surface 36 is provided on the side of the second extension portion 34 away from the first inclined surface 35, and the first inclined surface 35 and the second inclined surface 36 intersect. By providing the first inclined surface 35 and connecting the lower edge of the second abutting surface 32 to the first inclined surface 35, when the door lock catch structure 100 is close to the lock body 200 for mating, the first inclined surface 35 can be used to provide a guide for the door lock catch structure 100 to be inserted into the lock body 200 for engagement; that is, the first inclined surface 35 provides a guide path for the door lock catch structure 100, so that the lock catch 2 can be inserted into the lock body 200 more smoothly for engagement, which helps to reduce the friction and resistance during the insertion of the lock catch 2; and because the resistance of the lock catch 2 during the insertion process is reduced, the wear of the lock catch 2 and the lock body 200 can be reduced, thereby improving the durability of the entire structure. When the lock catch 2 is inserted into place, the side of the lock body 200 and the second abutting surface 32 abut and match, avoiding shaking between the lock body 200 and the lock catch 2, and preventing the lock catch 2 from accidentally coming out, thereby increasing the reliability of the locking between the door lock catch structure 100 and the lock body 200. By adding a second inclined surface 36 to cooperate with the first inclined surface 35, the intersection of the second inclined surface 36 and the first inclined surface 35 provides a clearer guiding path for the door lock structure 100 to be inserted into the lock body 200, which helps the lock 2 to be more accurately inserted into the lock body 200 to achieve engagement and reduce the possibility of misalignment.

[0048] In one embodiment, the door lock structure 100 further includes a base 1, one side of the base 1 is used to connect with the first door 400; the side of the base 1 facing away from the first door 400 is connected with the lock 2 and the buffer block 3. The base 1 is used to be detachably connected to the first door 400; the base 1 is detachably connected to the lock 2. Among them, the base 1 can be connected to the first door 400 by screw connection, snap connection, plug connection, bolt connection, rivet connection, etc., and the above connection methods have the advantages of stable connection and convenient installation and disassembly. And because there is a spacing 4 between the lock 2 and the buffer block 3, the lock 2 can adjust the connection position with the base 1 within a certain range to adapt to the position of the lock tongue in the lock body 200, which can improve the flexibility of matching.

[0049] In one embodiment, reference Figure 1The lock buckle 2 includes a first segment 21, a second segment 22, a third segment 23 and a fourth segment 24. One end of the first segment 21 is connected to the base 1, and the other end of the first segment 21 is connected to one end of the second segment 22. The second segment 22 is bent toward the side close to the base 1; the other end of the second segment 22 is connected to one end of the third segment 23, and the third segment 23 is bent toward the side close to the first segment 21; the other end of the third segment 23 is connected to one end of the fourth segment 24, and the other end of the fourth segment 24 is bent and connected to the base 1; the third segment 23 is used to buckle with the lock body 200 of the vehicle body 300. The first segment 21, the second segment 22, the third segment 23 and the fourth segment 24 are connected to form a continuous structure, and one end of the first segment 21 is connected to the base 1, and one end of the fourth segment 24 is also connected to the base 1 to form a fixed point of the lock buckle 2. The bending design of the first segment 21, the second segment 22, and the third segment 23 helps to ensure a firm connection between the lock buckle 2 and the lock body 200, and improves the locking reliability of the lock buckle and the lock body. The lock buckle 2 is configured as a multi-segment structure to disperse the force, reduce the stress concentration phenomenon in a single part, and thus improve the durability of the lock buckle 2.

[0050] In one embodiment, a groove 11 is provided on one side of the base 1 for connecting with the first door 400, and at least one first connection hole is provided on the inner wall of the groove 11, and the base 1 is detachably connected to the lock buckle 2 through the first connection hole. The groove 11 can improve the connection flatness between the base 1 and the mounting surface of the first door 400, reduce the gap, and thus improve the connection tightness between the base 1 and the first door 400. By providing at least one first connection hole on the inner wall of the groove 11, and connecting the base 1 with the lock buckle 2 by passing the first connection hole with the first fastener 13, the connection stability between the base 1 and the lock buckle 2 can be enhanced, and the loosening of the connection between the base 1 and the lock buckle 2 caused by vibration or impact generated during the driving of the vehicle can be reduced. The base 1 and the lock buckle 2 are detachably connected through the first fastener 13, and no complicated disassembly steps are required, making the maintenance of the base 1 and the lock buckle 2 more convenient. Among them, the first fastener 13 can be a screw.

[0051] In one embodiment, reference Figure 3 , Figure 6 and Figure 7, second connection holes 12 are also provided on both sides of the groove 11, and the base 1 is used to be detachably connected to the first door 400 through the second connection holes 12. The second fastener is passed through the second connection hole 12 to connect the base 1 to the first door 400, which can enhance the connection stability between the base 1 and the first door 400 and reduce the loosening of the connection between the base 1 and the first door 400 caused by vibration or impact generated during the driving of the vehicle. The base 1 and the first door 400 are detachably connected through the second fastener, and no complicated disassembly steps are required, making the maintenance of the base 1 more convenient. Among them, the second fastener can be a bolt.

[0052] Among them, the first abutment surface 31 is used for abutting the side surface of the lock body 200 facing the lock buckle 1, wherein the side surface of the lock body 200 facing the interior of the vehicle is perpendicular to the side surface of the lock body 1 facing the lock buckle. Therefore, by making the first abutment surface 31 and the second abutment surface 32 perpendicular, the abutment area of ​​the second abutment surface 32 with the side surface of the lock body 200 facing the interior of the vehicle can be increased, which helps to accurately match the door lock buckle structure 100 and the lock body 200, thereby improving the limiting effect on the lock body 200, reducing the shaking between the door lock buckle structure 100 and the lock body 200, improving the locking reliability of the door lock body 200 structure and the lock body 200, and reducing the unlocking failure or lock buckle 2 damage caused by improper position of the lock body 200.

[0053] In one embodiment, a protective layer (not shown) is provided on one side of the base 1 for connecting with the first door 400. The protective layer is provided to separate the base 1 from the mounting surface of the first door 400, thereby providing protection for the mounting surface of the first door 400 and preventing the mounting surface of the first door 400 from being damaged when the mounting position of the base 1 is adjusted. The protective layer may be a steel gasket or a plastic protective shell.

[0054] In one embodiment, a bending section 14 is provided on one side of the base 1, and the bending section 14 is bent toward the side of the base 1 on which the lock catch 2 is provided; the buffer block 3 is sleeved on the bending section 14. By providing the bending section 14, the buffer block 3 can be sleeved on the bending section 14 during installation, so that the buffer blocks 3 of different specifications and shapes can be replaced according to the lock bodies 200 of different specifications and shapes, thereby improving the adaptability of the door lock catch structure 100.

[0055] In one embodiment, reference Figure 1 and Figure 2The base 1, the first section 21, the second section 22, the third section 23 and the fourth section 24 are surrounded to form a locking plane, the locking plane is perpendicular to the second abutting surface 32, the locking plane is perpendicular to the first abutting surface 31, and the first abutting surface 31 is perpendicular to the second abutting surface 32; the locking plane is used to intersect with the inner surface of the first vehicle door 400 to form a first angle α, and the value range of the first angle α is 90° to 135°. One side of the first door 400 is rotatably connected to the body 300. When the first door 400 is opened or closed, the first door 400 and the body 300 can rotate relative to the body 300. By making the direction in which the lock catch 2 is inserted into the lock body 200 intersect with the inner surface of the first door 400 and form a first angle α, the lock catch 2 swings around the rotation axis of the first door 400, and the lock catch 2 swings in an arc; by making the value range of the first angle α be 90° to 135°, the lock catch 2 can smoothly mesh with the lock body 200 when it swings to the lock body 200. Among them, the locking plane is parallel to the YZ plane in the figure, the first abutting plane 31 is parallel to the XY plane, and the second abutting plane 32 is parallel to the XZ plane.

[0056] In one embodiment, reference Figure 2 The lock catch 2 can move on the first door 400 in a direction parallel to the first abutting surface 31 to adjust the relative position between the lock catch 2 and the first door 400. By making the lock catch 2 move on the first door 400 in a direction parallel to the first abutting surface 31, that is, making the lock catch 2 move on the first door 400 in a direction parallel to the XY plane, the purpose of adjusting the relative position between the lock catch 2 and the first door 400 is achieved, so that the lock catch 2 and the lock body 200 can be better locked. Specifically, the lock catch 2 is detachably connected to the base 1, and the base 1 is detachably connected to the first vehicle door 400.
