[0028] The utility model provides a vehicle door lock structure, comprising a lock member 1, an elastic member 2 and a mounting seat 3, wherein the lock member 1 is slidably connected to the mounting seat 3, and the two ends of the elastic member 2 are respectively connected to the lock member 1 and the mounting seat 3 to drive the lock member 1 to slide toward the inside of the vehicle.

[0029] Combination Figure 1 As shown, the side wall of the mounting seat 3 facing the opposite side of the X-axis in the figure is mounted in close contact with the inner wall of the door frame of the vehicle body, and the vehicle door is located on the side of the mounting seat 3 facing the positive side of the X-axis in the figure. When the vehicle door is closed, the door locking structure installed on the vehicle door is locked together with the lock member 1 on the door lock structure. In this embodiment, for the door lock structure, the direction toward the inside of the vehicle is Figure 1 The Y axis is in the opposite direction, and accordingly, the direction toward the outside of the vehicle is Figure 1 In the positive direction of the middle Y axis, when the vehicle door is closed, the elastic force of the elastic member 2 drives the locking member 1 to slide toward the inner side of the vehicle (i.e., in the opposite direction of the Y axis), and then drives the locked vehicle door to move toward the inner side of the vehicle (i.e., in the opposite direction of the Y axis) through the locking member 1, thereby converting the elastic force of the elastic member 2 into a closing holding force that pushes the vehicle door toward the inner side of the vehicle, thereby ensuring that the sealing strip, rubber plug and other structures between the vehicle door and the door frame are subjected to sufficient extrusion pressure.

[0030] It should be noted that, in this embodiment, the elastic member 2 may be an elastic structure such as a spring, an elastic strap, etc., and its specific location may be designed as required, as long as it can drive the locking member 1 to slide toward the inside of the vehicle through elastic force.

[0031] Furthermore, the lock component 1 includes a first slider 11 and a lock body 12. The lock body 12 is installed on the first slider 11 and is located on the side of the mounting seat 3 facing the vehicle door. The mounting seat 3 is provided with a first sliding groove 31 to slide with the first slider 11.

[0032] Combination Figure 1 As shown, specifically, the lock body 12 is in a C-shaped structure, with its two ends riveted to the first slider 11. The lock body 12 is located on the side of the mounting seat 3 facing the vehicle door (i.e., the side along the positive direction of the X-axis in the figure) so as to be locked with the vehicle door locking structure. The lock body 12 is installed on the first slider 11, and the first slider 11 is slidably connected in the first slide groove 31. The first slide groove 31 extends along the Y-axis direction in the figure, so that the elastic member 2 can drive the lock member 1 to slide in the opposite direction of the Y-axis in the figure, and the lock body 12 drives the vehicle door to move in the opposite direction of the Y-axis in the figure, so that the elastic force of the elastic member 2 is converted into a force that pushes the vehicle door to remain closed, which is beneficial to improving the sealing performance of structures such as sealing strips and rubber plugs between the vehicle door and the door frame, and avoiding abnormal noise problems caused by permanent deformation or aging of sealing strips and rubber plugs when opening and closing the vehicle door.

[0033] Furthermore, the locking component 1 also includes a second slider 13 connected to the first slider 11, the mounting seat 3 is provided with the first sliding groove 31 on the side wall facing the vehicle door, the mounting seat 3 is provided with a second sliding groove 32 on the side wall facing away from the vehicle door, and the second slider 13 is slidably connected in the second sliding groove 32.

[0034] Combination Figures 1 to 4 As shown, the first slider 11 and the second slider 13 are integrally connected, the lock body 12 is installed on the first slider 11, and the mounting seat 3 is provided with a first slide groove 31 and a second slide groove 32, wherein the first slide groove 31 is opened on the side wall of the mounting seat 3 facing the vehicle door (that is, the side wall of the mounting seat 3 facing the positive direction of the X-axis), and the second slide groove 32 is opened on the side wall of the mounting seat 3 facing away from the vehicle door (that is, the side wall of the mounting seat 3 facing away from the X-axis), and the first slide groove 31 and the second slide groove 32 are connected to each other, so that the first slider 11 slides in the first slide groove 31, and the second slider 13 slides in the second slide groove 32.

[0035] In this way, the first slider 11 and the second slider 13 are guided and slid along the first slide groove 31 and the second slide groove 32 respectively, which provides better guidance, so that the elastic force of the elastic member 2 can act on the vehicle door without deviation, so as to better press the vehicle door to maintain the sealing performance of the sealing strip, rubber plug and other structures between the vehicle door and the door frame.

[0036] Preferably, a stopper 131 is provided on the second sliding block 13 , one end of the elastic member 2 is connected to the inner wall of the second sliding groove 32 , and the other end is connected to the side wall of the stopper 131 facing the outer side of the vehicle.

[0037] Combination Figure 2 As shown, the stopper 131 is integrally connected to the second slider 13, and the side wall of the stopper 131 facing the outside of the vehicle (i.e., the side wall facing the positive direction of the Y-axis) is connected to one end of the elastic member 2, and the other end of the elastic member 2 is connected to the inner wall of the second slide groove 32. The elastic force of the elastic member 2 acts on the side wall of the stopper 131 facing the positive direction of the Y-axis, thereby driving the second slider 13, the first slider 11 and the lock body 12 to move in the opposite direction of the Y-axis.

[0038] In this way, the elastic force of the elastic member 2 can act on the side wall of the block 131 toward the outside of the vehicle, thereby pushing the block 131 to drive the locking member 1 as a whole to slide toward the inside of the vehicle, thereby driving the door to move toward the inside of the vehicle when the door is closed, so that the sealing strip, rubber plug and other structures between the door and the door frame are subjected to a certain extrusion pressure to maintain the sealing performance.

[0039] Specifically, the side wall of the mounting seat 3 facing away from the vehicle door is used to be mounted on the inner wall of the door frame, and the side wall of the stopper 131 facing away from the vehicle door is used to slide with the inner wall of the door frame.

[0040] Combination Figure 2 As shown, mounting holes are respectively arranged on the side wall of the mounting seat 3 facing away from the vehicle door and on the inner wall of the door frame, and the mounting seat 3 is fixedly mounted on the inner wall of the door frame by fasteners such as bolts or screws, so that the side wall of the mounting seat 3 facing away from the vehicle door and the inner wall of the door frame are in contact with each other, and the side wall of the stopper 131 facing away from the vehicle door and the inner wall of the door frame are slidably matched, so that the second slider 13 is guided by the second slide groove 32 and the inner wall of the door frame, thereby further improving the sliding stability of the second slider 13 and avoiding the second slider 13 from deflecting when sliding.

[0041] Preferably, side plates 132 are provided on both sides of the stopper 131 , and the side plates 132 and the stopper 131 form a groove structure, and one end of the elastic member 2 is connected to the groove structure.

[0042] Combination Figure 2 and Figure 3 As shown, the side panels 132 are integrally connected to both sides of the stop block 131, and the side panels 132 and the stop block 131 on both sides form a groove structure. The side panels 132 form the inner side wall of the groove structure, and the stop block 131 forms the inner bottom wall of the groove structure. The end of the elastic member 2 is connected to the side wall of the stop block 131 facing the outside of the vehicle, that is, the inner bottom wall of the groove structure, so that the second slider 13 can be pushed toward the inside of the vehicle as a whole. At the same time, the side panels 132 can prevent the end of the elastic member 2 from accidentally detaching from the stop block 131, thereby better ensuring the sealing performance of structures such as the sealing strip between the door and the door frame.

[0043] Furthermore, the width of the first slide groove 31 is smaller than the width of the second slide groove 32, so that a groove shoulder structure 33 is formed at the connecting position between the first slide groove 31 and the second slide groove 32, and the groove shoulder structure 33 and the second slider 13 slide toward the side wall of the vehicle door.

[0044] Combination Figure 4 As shown, the width of the first slide groove 31 is smaller than the width of the second slide groove 32, so that a groove shoulder structure 33 is formed at the position where the first slide groove 31 and the second slide groove 32 are connected to each other. Figure 3 The second slider 13 is fitted to the side wall in the positive direction of the X-axis and can slide relatively, so that the groove shoulder structure 33 plays a certain guiding role, further improving the sliding stability of the second slider 13 and avoiding the deflection of the second slider 13 when sliding.

[0045] Preferably, the side wall of the first sliding block 11 extends obliquely from the second sliding block 13 toward the vehicle door to form an inclined surface structure 111 , and the inner wall of the first sliding groove 31 is slidably matched with a portion of the inclined surface structure 111 .

[0046] Combination Figure 1 and Figure 3 As shown, the side wall of the first slider 11 is an inclined structure 111, which starts from the side wall of the second slider 13 toward the positive direction of the X-axis, and extends obliquely toward the positive direction of the X-axis, so that the first slider 11 as a whole forms a boss with a gradually decreasing cross-sectional area. The side wall of the boss is the inclined structure 111. When the locking member 1, the elastic member 2 and the mounting seat 3 are assembled, the inclined structure 111 plays a certain assembly guiding role, which facilitates the first slider 11 to be installed in the first slide groove 31. At the same time, part of the inclined structure 111 slides in cooperation with the inner wall of the first slide groove 31, which can guide the locking member 1.

[0047] In the door lock structure of the utility model, the two ends of the elastic member 2 are respectively connected to the lock member 1 and the mounting seat 3, and the lock member 1 and the mounting seat 3 are slidingly connected and matched. After the vehicle door is closed, the vehicle door is locked on the lock member 1. The elastic member 2 is compressed at this time and generates a thrust on the lock member 1 and the vehicle door, pressing the vehicle door toward the inside of the vehicle. Even if the sealing strip, rubber plug and other structures between the vehicle door and the door frame are permanently compressed and deformed and the elastic force is attenuated, the elastic member 2 can apply a closing holding force to the vehicle door to maintain the sealing performance of the sealing strip and other structures between the vehicle door and the door frame, thereby avoiding problems such as abnormal noise, vibration, air leakage, water leakage, etc. caused by loose sealing strips when opening and closing the vehicle door, thereby improving the NVH performance of the whole vehicle.

[0048] The utility model also provides a vehicle, comprising the vehicle door lock structure.

[0049] The vehicle of the present invention adopts the above-mentioned door lock structure, and the two ends of the elastic member 2 are respectively connected to the lock member 1 and the mounting seat 3, and the lock member 1 and the mounting seat 3 are slidingly connected and matched. After the door is closed, the door is locked on the lock member 1. The elastic member 2 is compressed at this time and generates a thrust on the lock member 1 and the door, pressing the door toward the inside of the vehicle. Even if the sealing strip, rubber plug and other structures between the door and the door frame are permanently compressed and deformed and the elastic force is attenuated, the elastic member 2 can apply a closing retention force to the door to maintain the sealing performance of the sealing strip and other structures between the door and the door frame, so as to avoid problems such as abnormal noise, vibration, air leakage, water leakage, etc. caused by loose sealing strips when opening and closing the door, thereby improving the NVH performance of the whole vehicle.
