[0002] Generally, a B-pillar-free vehicle omits the B-pillar in the vehicle body, so that the space for entering and exiting the vehicle is more spacious when the door is opened. However, since the vehicle has no B-pillar, there is no component for supporting the door structure in the inner and outer directions between the front and rear doors of the vehicle.

[0003] The door lock is used to connect the door to the vehicle body. For vehicles with double doors without B-pillars, since there is no B-pillar, the door locks are arranged on the upper and lower sides of the door, the ground lock is arranged at the door sill, and the upper lock is arranged at the window frame of the door. After the door is closed, the ground lock and the upper lock limit the door in the inner and outer directions. However, since there is no support from the B-pillar, the door lock will be subjected to a large collision force when the door is closed, which will cause the door lock to deform or even be damaged.

[0033] Please also read Figures 1 to 3The vehicle door lock protection structure and the vehicle door assembly provided by the utility model are now described. The vehicle door lock protection structure includes a limiting component 10 and a fixing component 20. The limiting component 10 is connected to the vehicle door 30 and has a limiting portion extending downward from the vehicle door 30. The fixing component 20 is connected to the vehicle body 40. When the vehicle door 30 is closed, the limiting portion abuts against the fixing component 20 in the inner and outer directions.

[0034] Compared with the prior art, the door lock protection structure provided by the utility model is provided with a limiting assembly 10 on the door 30, and the fixing assembly 20 corresponds to the limiting assembly 10 in the inner and outer directions and is connected to the vehicle body 40. After the door 30 is closed, the limiting assembly 10 contacts the fixing assembly 20 in the inner and outer directions, so as to alleviate the impact force or collision force generated by the closing of the door 30, and prevent the door lock from being deformed or damaged due to the impact force or collision force generated by the closing of the door 30. When the door 30 is closed, the limiting assembly 10 abuts against the fixing assembly 20 in the inner and outer directions, and then limits the door 30 in the inner and outer directions. When the vehicle is hit sideways, the door 30 is subjected to an inward impact force. Since the limiting assembly 10 abuts against the fixing assembly 20, it resists the external force impact together with the door 30, which can not only reduce the probability of deformation of the door 30 and protect the safety of the passengers in the vehicle, but also avoid the problem of deformation or damage of the door 30 lock caused by the inward deformation of the door 30, and improve the impact resistance of the door 30 lock.

[0035] Optionally, the limiting assembly 10 is located on one side of the door lock, for example, spaced apart from the door lock along the front-to-back direction, or spaced apart from the door lock along a path that forms an angle with the front-to-back direction.

[0036] In some embodiments, see Figures 1 to 3 The limiting assembly 10 includes a limiting member 103 and a mounting member 101 . One end of the limiting member 103 is connected to the vehicle door 30 , and the other end extends downward to form a limiting portion of the vehicle door 30 . The mounting member 101 fixes the limiting member 103 to the vehicle door 30 .

[0037] The stopper 103 is fixed to the vehicle door 30 by the mounting member 101. Compared with the solution of directly fixing the stopper 103 to the vehicle door 30, the structure of the stopper 103 is simplified and the processing is more convenient. In addition, compared with directly welding or bonding the stopper 103 to the vehicle door 30, the stopper 103 is fixed by the mounting member 101, which can increase the contact area with the stopper 103 and improve the firmness of the connection.

[0038] Optionally, the mounting member 101 is disposed on the vehicle door 30 and is screwed or clamped to the position limiting member 103. For example, the mounting member 101 is welded to the vehicle door 30 and is clamped or screwed to the position limiting member 103.

[0039] Optionally, the limiting member 103 is provided with a limiting hole, and the mounting member 101 is welded to the vehicle door 30 and inserted into the limiting hole.

[0040] In some embodiments, see Figures 1 to 3 The connection end of the limiting member 103 is adapted to the through hole of the vehicle door 30 , and the mounting member 101 is provided with a mounting hole for the connection end of the limiting member 103 to pass through, and the connection end of the limiting member 103 is inserted into the through hole and the mounting hole.

[0041] The stopper 103 is inserted into the through hole of the door 30, and there is no need to align the position during installation, so quick installation can be achieved. Then, the mounting hole of the mounting member 101 is sleeved outside the stopper 103 to lock the stopper 103. The solution in this embodiment does not need to fix the mounting member 101 to the door 30, which simplifies the installation steps and does not require positioning, thereby improving installation efficiency.

[0042] Optionally, the connection end of the limiting portion has an external thread, and the mounting hole is a threaded hole, which is threadedly connected to the limiting portion.

[0043] In some embodiments, see Figures 1 to 3 The limiting assembly 10 further includes a reinforcing plate 102 attached to the vehicle door 30 , the reinforcing plate 102 is provided with a clearance hole for avoiding the limiting member 103 , the clearance hole is arranged corresponding to the through hole, and the limiting member 103 is inserted into the clearance hole.

[0044] The reinforcing plate 102 can increase the strength of the door 30 to prevent the door 30 and the stopper 103 from being damaged due to the reduced strength caused by the opening of the through hole. The stopper 103 is connected to the mounting member 101 after passing through the clearance hole and the through hole.

[0045] Optionally, the reinforcing plate 102 is bonded or welded to the vehicle door 30 to improve the connection stability between the reinforcing plate 102 and the vehicle door 30 and avoid the problem of the reinforcing plate 102 rotating due to the loosening of the limiting member 103 .

[0046] Optionally, the reinforcing plate 102 includes a first plate body and a second plate body that are distributed at an angle, and the first plate body and the second plate body are respectively attached to two adjacent plate surfaces of the vehicle door 30. This can not only increase the contact area between the reinforcing plate 102 and the vehicle door 30, increase the firmness of the connection, but also improve the strength of the reinforcing plate 102.

[0047] In some embodiments, see Figures 1 to 3 The limiting member 103 includes a limiting rod 1031 and a reinforcing block 1032. One end of the limiting rod 1031 is connected to the vehicle door 30, and the other end extends downward to the vehicle door 30. The reinforcing block 1032 is connected to the extended end of the limiting rod 1031, and together with the extended end of the limiting rod 1031, forms a limiting portion, and the reinforcing block 1032 protrudes from the limiting rod 1031.

[0048] The provision of the reinforcement block 1032 not only increases the strength of the stopper 103, but also increases the contact area with the fixing assembly 20, and reduces the pressure of the fixing assembly 20 after the stopper abuts against the fixing assembly 20. In addition, compared with the solution in which both the stopper rod 1031 and the reinforcement block 1032 are provided as large-volume components, this embodiment avoids the problem that the stopper 103 is too large in volume and weight and occupies too much space, which is conducive to achieving lightweight of the entire vehicle and saving materials.

[0049] Specifically, the outer circumferential surface of the reinforcement block 1032 is convex from the outer circumferential surface of the limiting rod 1031 .

[0050] In some embodiments, see Figures 1 to 3 The limiting assembly 10 also includes a buffer sleeve sleeved outside the limiting portion, and the buffer sleeve is a flexible component.

[0051] The buffer sleeve can prevent the limiting part from direct contact with the fixing assembly 20, and alleviate the impact force generated when the limiting part abuts against the fixing assembly 20. It can not only prevent the limiting part and the fixing assembly 20 from being damaged by the impact force, but also reduce the noise generated by the collision, which is beneficial to improving the NVH performance of the entire vehicle.

[0052] Optionally, the buffer sleeve may be a rubber component or an EVA component.

[0053] As a specific embodiment of the fixing assembly 20, the surface of the fixing assembly 20 in contact with the limiting part is provided with an anti-collision layer, which can alleviate the abutment force when the limiting part abuts against the fixing assembly 20, improve the service life of the limiting part and the fixing assembly 20, and reduce the noise generated during the collision. The anti-collision layer can be a rubber layer or an EVA layer, which is bonded to the fixing assembly 20.

[0054] In some embodiments, see Figures 1 to 3 The fixing assembly 20 includes a fixing plate 201 and a supporting seat 202 . The fixing plate 201 is connected to the vehicle body 40 . The supporting seat 202 is connected to the fixing plate 201 . The supporting seat 202 abuts against the limiting assembly 10 in the inner and outer directions.

[0055] The fixing plate 201 is connected to the vehicle body 40, and the support seat 202 extends upward from the fixing plate 201 and abuts against the limiting portion in the inner and outer directions to limit the position of the vehicle door 30 in the inner and outer directions. The solution in this embodiment adopts a simple structure to abut against the limiting portion, which is easy to process, and the support seat 202 can also contact the vehicle door 30 in the upper and lower directions, thereby providing support force for the vehicle door 30 in the upper and lower directions.

[0056] Optionally, the fixed plate 201 and the supporting seat integral structure may also be fixedly connected by welding or screwing.

[0057] Optionally, the fixing plate 201 is welded to the vehicle body 40 , or may be screwed or clamped to the vehicle body 40 .

[0058] In some embodiments, see Figures 1 to 3 The fixing assembly 20 is provided with a limiting groove 2021 adapted to the limiting portion. After the vehicle door 30 is closed, the limiting portion is inserted into the limiting groove 2021 along the inner and outer directions.

[0059] The limiting part is inserted into the limiting groove 2021, which increases the contact area between the limiting part and the fixing assembly 20, and improves the stability after the limiting part abuts against the fixing assembly 20. At the same time, the limiting groove 2021 can provide a restraining force to the limiting part in the front-to-back direction, and when the vehicle hits the side, the limiting part is prevented from being displaced in the front-to-back direction due to the collision force, ensuring that effective support force can be provided to the door 30 in the inside-outside direction, protecting the door 30 lock from damage.

[0060] In some embodiments, see Figures 1 to 3 The fixing plate 201 is provided with a first fixing hole 2011 , the first fixing hole 2011 is adapted to the second fixing hole on the vehicle body 40 , and a locking member 203 is inserted into the first fixing hole 2011 and the second fixing hole.

[0061] After the first fixing hole 2011 of the fixing plate 201 corresponds to the second fixing hole of the vehicle body 40, the locking member 203 is inserted into the first fixing hole 2011 and the second fixing hole to achieve the connection between the fixing plate 201 and the vehicle body 40. Compared with the welding method, this embodiment is more convenient and quick to install, and at the same time avoids the problem of welding through the fixing plate 201 during welding.

[0062] Optionally, the locking member 203 is a threaded member or a clamping member, and the fixing plate 201 is fixed to the vehicle body 40 by screwing or clamping.

[0063] Optionally, the first fixing hole 2011 is a countersunk hole. After the locking member 203 is inserted into the first fixing hole 2011, the end of the locking member 203 is prevented from being exposed outside the fixing plate 201, which not only reduces the problem of interference with other components, but also avoids the problem of the locking member 203 being loosened due to external force.

[0064] Based on the same inventive concept, the utility model also provides a vehicle door assembly. Figure 3 The door assembly includes any one of the above-mentioned door lock protection structures.

[0065] The door assembly provided by the utility model adopts the above-mentioned door lock protection structure. The limiting assembly 10 is arranged on the door 30, and the fixing assembly 20 corresponds to the limiting assembly 10 in the inner and outer directions and is connected to the vehicle body 40. After the door 30 is closed, the limiting assembly 10 contacts the fixing assembly 20 in the inner and outer directions, so as to alleviate the impact force or collision force generated by the closing of the door 30, and prevent the door lock from being deformed or damaged due to the impact force or collision force generated by the closing of the door 30. When the door 30 is closed, the limiting assembly 10 abuts against the fixing assembly 20 in the inner and outer directions, and then limits the door 30 in the inner and outer directions. When the vehicle is hit sideways, the door 30 is subjected to an inward impact force. Since the limiting assembly 10 abuts against the fixing assembly 20, it resists the external force impact together with the door 30, which can not only reduce the probability of deformation of the door 30 and protect the safety of the passengers in the vehicle, but also avoid the problem of deformation or damage of the door 30 lock caused by the inward deformation of the door 30, and improve the impact resistance of the door 30 lock.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
