[0039] 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. Among them, the lock buckle and the lock body switch need to be coordinated when the car door is locked, and the impact will occur when the car door is closed, which may cause the lock body and the car door lock buckle to deform or wear. After the car door lock buckle and the lock body are deformed or worn, the car door lock buckle and the lock body are prone to misalignment during the locking process, resulting in reduced locking reliability between the car door lock body and the lock buckle.
[0040] See also Figures 1 to 6 In one embodiment of the present application, the lock structure 100 includes a lock 1 and a buffer block 2, the lock 1 is used to connect with the vehicle body 300 or the first vehicle door 400, and the lock 1 is used to buckle with the lock body 200; when the lock 1 is connected to the vehicle body 300, the lock body 200 is connected to the first vehicle door 400; when the lock 1 is connected to the first vehicle door 400, the lock body 200 is connected to the vehicle body 300 or another vehicle door; the buffer block 2 is connected to the lock 1; the buffer block 2 is used to abut against the lock body 200 and perform buffering.
[0041] In this embodiment, the buffer block 2 is made of a material that can absorb energy and buffer based on its own elastic deformation. During the closing process of the first door 400, when the lock buckle 1 is about to be inserted into the lock body 200 and is buckled with the lock body 200, the lock body 200 abuts against the buffer block 2 and pushes the buffer block 2 to undergo elastic deformation, so that the elastic deformation of the buffer block 2 can be used to buffer the impact force generated by the first door 400, which can avoid deformation and wear of the lock body 200 and the lock buckle 1 under the impact force to a certain extent, reduce the probability of misalignment of the lock body 200 and the lock buckle 1 during the locking process, and thus improve the locking stability and reliability between the lock body 200 and the lock buckle 1.
[0042] In one embodiment, reference Figures 1 to 6The lock buckle 1 is used to connect with the first vehicle door 400, and the buffer block 2 is provided with a contact surface 21; during the process of the lock buckle 1 being fastened with the lock body 200, the contact surface 21 is used to abut with the lock body 200 to buffer the movement of the lock buckle 1 along the fastening direction.
[0043] Furthermore, the buffer block 2 is also provided with an inclined surface 22 , and the abutting surface 21 intersects with the inclined surface 22 ; the abutting surface 21 is used to abut against a side surface of the lock body 200 facing the lock buckle 1 , and the inclined surface 22 forms an angle with the side surface of the lock body 200 facing the lock buckle 1 .
[0044] In the above structure, the lock buckle 1 and the buffer block 2 are connected to the first vehicle door 400, and the buffer block 2 is provided with an abutting surface 21 and an inclined surface 22, wherein the abutting surface 21 and the inclined surface 22 intersect; when the lock buckle 1 is buckled with the lock body 200 of the vehicle body 300, the abutting surface 21 of the buffer block 2 abuts against the side surface of the lock body 200 facing the lock buckle 1, and the inclined surface 22 of the buffer block 2 forms an angle α with the side surface of the lock body 200 facing the lock buckle 1; therefore, during the closing process of the first vehicle door 400, the abutting surface 21 of the buffer block 2 abuts against the lock body 200 to buffer the impact force generated by the first vehicle door 400, which can reduce the deformation of the lock body 200 and the lock buckle 1 and improve the locking stability of the lock body 200 and the lock buckle 1; and during the closing process of the first vehicle door 400, the first vehicle door 400 realizes the closing action by swinging around the rotation axis, and the first vehicle door 400 swings When the lock is moved, the lock buckle 1 and the buffer block 2 are driven to swing until the lock buckle 1 is inserted into the lock body 200 and buckled with the lock body 200; and in the process of inserting the lock buckle 1 into the lock body 200, the inclined surface 22 provides an insertion guide for the lock buckle structure 100, which can avoid the misalignment between the lock buckle 1 and the lock body 200, and further improve the locking stability of the lock body 200 and the lock buckle 1; and because the abutting surface 21 abuts against the side surface of the lock body 200 facing the lock buckle 1, the abutting surface 21 of the buffer block 2 provides a limiting effect between the lock buckle structure 100 and the lock body 200, further improving the locking stability of the lock body 200 and the lock buckle 1; the buffer block 2 added to the lock buckle structure 100 can have the functions of buffering, limiting and guiding at the same time, reducing the limiting parts and guiding parts required to be used, reducing the overall volume of the lock buckle structure 100, and reducing the layout space required for the lock buckle structure 100 as a whole.
[0045] In one embodiment, reference Figures 4 to 6, the value range of the angle α is 5°~75°. By making the inclined surface 22 and the surface of the lock body 200 facing the lock buckle 1 form an angle α of 5°~75°, the lock buckle structure 100 is inserted into the lock body 200 to provide an escape space for the relative movement between the buffer block 2 and the lock body 200; and during the closing process of the first door 400, the first door 400 swings around the rotation axis to achieve the closing action, and the inclined surface 22 of the buffer block 2 provides a guide path for the relative movement between the buffer block 2 and the lock body 200, so that the lock buckle 1 can be inserted into the lock body 200 more smoothly to achieve engagement, which helps to reduce the friction and resistance during the insertion process of the lock buckle 1.
[0046] In one embodiment, reference Figure 1 and Figure 6 The buffer block 2 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 2 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.
[0047] In one embodiment, reference Figure 2 , the lock catch 1 can move on the first door 400 in a direction parallel to the direction in which the lock catch 1 is inserted into the lock body 200, so as to adjust the relative position between the lock catch 1 and the first door 400. By moving the lock catch 1 on the first door 400 in a direction parallel to the direction in which the lock catch 1 is inserted into the lock body 200, that is, by moving the lock catch 1 on the first door 400 in a direction parallel to the Z direction, the purpose of adjusting the relative position between the lock catch 1 and the first door 400 is achieved, so that the lock catch 1 and the lock body 200 can be better locked. The lock catch 1 is detachably connected to the vehicle body 300 or another vehicle door, and the connection position of the lock body 200 with the vehicle body 300 or another vehicle door can also be adjusted so that the lock body 200 cooperates with the lock catch 1, thereby improving the locking accuracy of the lock catch 1 and the lock body 200 and reducing the wear between the lock catch 1 and the lock body 200.
[0048] In one embodiment, reference Figure 1The lock buckle 1 includes a first segment 11, a second segment 12 and a third segment 13. One end of the first segment 11 is used to connect with the first vehicle door 400, and the other end of the first segment 11 is connected to one end of the second segment 12. The second segment 12 is bent toward the side close to the first segment 11; the other end of the second segment 12 is connected to one end of the third segment 13, and the other end of the third segment 13 is used to connect with the first vehicle door 400; the first segment 11 or the second segment 12 or the third segment 13 is used to buckle with the lock body 200. The first segment 11, the second segment 12 and the third segment 13 are connected to form a continuous structure, and one end of the first segment 11 is connected to the base 3, and one end of the third segment 13 is also connected to the base 3 to form a fixed point of the lock buckle 1. The bending design of the first segment 11, the second segment 12 and the third segment 13 helps to ensure a firm connection between the lock buckle 1 and the lock body 200, and improve the locking reliability of the lock buckle 1 and the lock body 200. The lock buckle 1 is configured as a multi-segment structure to disperse force and reduce stress concentration in a single location, thereby improving the durability of the lock buckle 1.
[0049] In one embodiment, reference Figure 1 , Figure 5 and Figure 6 The lock structure 100 further includes a base 3, one side of the base 3 is used to connect with the first door 400, and the side of the base 3 away from the first door 400 is connected with the lock 1 and the buffer block 2. The base 3 can be connected with the first door 400 by screw connection, snap connection, plug connection, bolt connection, rivet connection, etc. The above connection methods have the advantages of stable connection and convenient installation and disassembly.
[0050] In one embodiment, reference Figure 1 , Figure 2 and Figure 6 The base 3, the first segment 11, the second segment 12 and the third segment 13 surround and form a locking plane, which is parallel to the direction in which the lock buckle 1 is inserted into the lock body 200; the locking plane is perpendicular to the abutment surface 21. Therefore, by making the locking plane parallel to the direction in which the lock buckle 1 is inserted into the lock body 200, it is helpful for the lock buckle 1 to be inserted into the lock body 200 and achieve buckling; when the lock buckle 1 is inserted, by making the locking plane perpendicular to the abutment surface 21, the abutment surface 21 is used to limit the lock body 200, which reduces the shaking between the lock buckle structure 100 and the lock body 200, improves the locking reliability of the lock body 200 structure and the lock body 200, and reduces the situation of unlocking failure or damage to the lock buckle 1 due to improper position of the lock body 200.
[0051] In one embodiment, reference Figure 6The side of the base 3 used for connecting with the first door 400 is provided with a protective layer (not shown in the figure).

The protective layer can be a steel gasket or a plastic protective shell.
[0052] In one embodiment, reference Figure 6 A groove 31 is provided on one side of the base 3 for connecting with the first vehicle door 400, and at least one first connecting hole is provided on the inner wall of the groove 31, through which the base 3 is detachably connected to the lock buckle 1; second connecting holes 32 are also provided on both sides of the groove 31, through which the base 3 is detachably connected to the first vehicle door 400.
[0053] In one embodiment, reference Figure 3 A bending section 33 is provided on one side of the base 3, and the bending section 33 is bent toward the side of the base 3 where the lock buckle 1 is provided; the buffer block 2 is sleeved on the bending section 33. By providing the bending section 33, the buffer block 2 can be sleeved on the bending section 33 during installation, so that the buffer block 2 of different specifications and shapes can be replaced according to the lock body 200 of different specifications and shapes, and the adaptability of the lock buckle structure 100 can be improved.
[0054] The technical solution of the present application is to connect the lock buckle 1 and the buffer block 2 with the first vehicle door 400, and the buffer block 2 is provided with a contact surface 21 and an inclined surface 22, and the contact surface 21 and the inclined surface 22 intersect; when the lock buckle 1 is buckled with the lock body 200 of the vehicle body 300, the contact surface 21 of the buffer block 2 abuts against the side surface of the lock body 200 facing the lock buckle 1, and the inclined surface 22 of the buffer block 2 forms an angle α with the side surface of the lock body 200 facing the lock buckle 1; therefore, when the first vehicle door 400 is closed, the abutment surface 21 of the buffer block 2 abuts against the lock body 200 to buffer the impact force generated by the first vehicle door 400, which can reduce the deformation of the lock body 200 and the lock buckle 1 and improve the locking stability of the lock body 200 and the lock buckle 1; and during the closing process of the first vehicle door 400, the first vehicle door 400 realizes the closing action by swinging around the rotation axis, and the first vehicle door 400 swings When the lock is moved, the lock buckle 1 and the buffer block 2 are driven to swing until the lock buckle 1 is inserted into the lock body 200 and buckled with the lock body 200; and in the process of inserting the lock buckle 1 into the lock body 200, the inclined surface 22 provides an insertion guide for the lock buckle structure 100, which can avoid the misalignment between the lock buckle 1 and the lock body 200, and further improve the locking stability of the lock body 200 and the lock buckle 1; and because the abutting surface 21 abuts against the side surface of the lock body 200 facing the lock buckle 1, the abutting surface 21 of the buffer block 2 provides a limiting effect between the lock buckle structure 100 and the lock body 200, further improving the locking stability of the lock body 200 and the lock buckle 1; the buffer block 2 added to the lock buckle structure 100 can have the functions of buffering, limiting and guiding at the same time, reducing the limiting parts and guiding parts required to be used, reducing the overall volume of the lock buckle structure 100, and reducing the layout space required for the lock buckle structure 100 as a whole.
