[0029] Please refer to Figure 1-8 In one aspect of the present application, a door lock reinforcement device 100 is provided, which is installed at the door lock of a vehicle door, and the door lock reinforcement device 100 includes a first side panel 1, a second side panel 2 and a bottom panel 3. Specifically, the first side panel 1 and the second side panel 2 are both connected to the bottom panel 3, and are both located on the same side of the bottom panel 3. The first side panel 1, the second side panel 2 and the bottom panel 3 enclose an open space, which can improve the rigidity of the door lock installation point and enhance the NTF performance. Furthermore, at least one of the first side panel 1 and the second side panel 2 is provided with a leakage hole 4, which can prevent rainwater or coating electrophoretic liquid from accumulating in the open space.
[0030] Specifically, the first side panel 1 and the bottom panel 3 are installed at the door lock, and the first side panel 1 and the bottom panel 3 are connected by the second side panel 2, which can improve the stiffness of the installation point at the door lock, improve the stability, and thus improve the NTF performance. Further, the first side panel 1, the second side panel 2 and the bottom panel 3 are installed on the door inner panel 200, and the door inner panel 200 is connected to the door outer panel. The first side panel 1, the second side panel 2 and the bottom panel 3 are enclosed to form an open space, which can improve the stiffness of the door inner panel 200, thereby improving the dynamic stiffness of the door outer panel, reducing the resonance frequency of the door outer panel, and thus improving the NTF performance. In a specific embodiment, a leakage hole 4 can be provided on the second side panel 2 to prevent rainwater or coating electrophoretic liquid from accumulating in the open space. In another specific embodiment, a leakage hole 4 can also be provided on the first side panel 1. In other embodiments, a leakage hole 4 can also be provided on both the first side panel 1 and the second side panel 2.
[0031] In one embodiment of the present application, a welding area 31 is provided at one end of the bottom plate 3 away from the first side plate 1 , and the bottom plate 3 is welded to the door inner panel 200 via the welding area 31 .
[0032] Specifically, the welding area 31 is located at one end of the bottom plate 3 away from the door lock hole, and the other side of the door inner plate 200 away from the bottom plate 3 is connected and fixed to the door outer plate. The welding area 31 forms a pit at the corresponding position of the other side of the door inner plate 200, and the door outer plate can cover the pit so that the pit is not exposed on the front of the door lock, thereby beautifying the appearance of the door inner plate 200. It should be noted that the front direction of the door lock may include the direction in which the door inner plate 200 is away from the bottom plate 3. The bottom plate 3 is welded to the door inner plate 200 through the welding area 31, and a corresponding welding pit is formed on the door inner plate 200. Since the welding area 31 is located at one end of the bottom plate 3 away from the first side plate 1, the door outer plate connected and fixed to the door inner plate 200 can cover the trace of the pit, thereby making the pit not exposed on the front of the door lock, thereby beautifying the appearance of the door inner plate 200.
[0033] In one embodiment of the present application, the door lock reinforcement device is further provided with a glue-coated engraving 5 , which is arranged on the bottom plate 3 and extends to the first side plate 1 .
[0034] Specifically, the bottom plate 3 and the first side plate 1 of the door lock reinforcement device 100 are fixed to the door inner panel 200 by gluing. By setting the glue engraving 5, it is convenient for workers to identify the gluing track, reduce incorrect coating, improve the accuracy of gluing, and thus improve work efficiency and production efficiency.
[0035] In one embodiment of the present application, the glue coating engraving 5 includes a first part 51, a second part 52, a third part 53 and a fourth part. Specifically, the first part 51, the second part 52 and the third part 53 are arranged on the bottom plate 3, the fourth part (not shown in the figure) is arranged on the first side plate 1 and extends toward the bottom plate 3, the first part 51 extends toward the first side plate 1 and is connected to the fourth part, the second part 52 is connected to the first part 51 and extends away from the second side plate 2, and the third part 53 is connected to the second part 52 and extends toward the first side plate 1.
[0036] Specifically, the first portion 51 and the second portion 52 extend in different directions, and the second portion 52 and the third portion 53 extend in different directions, so that a portion of the glue-coated engraving 5 is bent and arranged on the bottom plate 3 to increase the coating area of the glue on the bottom plate 3, thereby increasing the contact area between the glue and the bottom plate 3, thereby improving the adhesion of the glue and improving the stability of the bonding between the bottom plate 3 and the door inner plate. In another specific embodiment, the fourth portion can also be bent and arranged on the first side plate 1 to enhance the adhesion of the glue on the first side plate 1. In other specific embodiments, the extension and bending directions of the glue-coated engraving 5 can also include other directions, which will not be repeated here.
[0037] In one embodiment of the present application, the first side plate 1 is provided with a positioning hole 6 , and the positioning hole 6 extends along the moving direction of the door lock reinforcement device 100 in a long strip shape.
[0038] Specifically, the positioning hole 6 is used to adjust the position of the door lock reinforcement device 100 on the door inner panel 200 and position it. Positioning members, such as bolts, positioning pins, etc., pass through the door inner panel 200 and the positioning hole 6 in sequence to position and fasten the first side panel 1 so that the first side panel 1 is connected and fixed to the door inner panel 200.
[0039] Furthermore, the positioning hole 6 extends in a long strip shape along the moving direction of the door lock reinforcement device 100, that is, the position of the positioning member in the positioning hole 6 can be adjusted. Through the different positions of the positioning member along the moving direction of the door lock reinforcement device 100, the position of the first side panel 1 relative to the door inner panel 200 can be adjusted to facilitate subsequent maintenance and repair and reduce maintenance costs.
[0040] Furthermore, the moving direction is the direction from the first side panel 1 toward the bottom panel 3, that is, the positioning hole 6 can extend along the direction from the first side panel 1 toward the bottom panel 3, and the distance between the bottom panel 3 and the door inner panel 200 can be adjusted by positioning the positioning piece at different positions of the positioning hole 6, thereby facilitating later maintenance and repair and reducing maintenance costs.
[0041] On the other hand, the present application further provides a vehicle, which includes the above-mentioned door lock strengthening device 100. Specifically, since the vehicle includes the door lock strengthening device 100 described in the above embodiment, it also has the beneficial effects of the above-mentioned door lock strengthening device 100, which will not be repeated here.
[0042] Furthermore, the side of the door lock reinforcement device 100 facing away from the open space is installed on the door inner panel 200, that is, the first side panel 1 and the bottom panel 3 are both installed on the door inner panel 200, and the first side panel 1 is connected and fixed to the bottom panel 3 by the second side panel 2 to improve the stiffness of the installation point at the door lock, and the door inner panel 200 is connected to the door outer panel. The door lock reinforcement device 100 can also further improve the dynamic stiffness of the door outer panel, reduce the resonance frequency of the door outer panel, and improve the NTF performance.
[0043] Furthermore, the vehicle also includes a positioning member (not shown in the figure), which passes through the positioning holes 6 on the door inner panel 200 and the first side panel 1 in sequence. The positioning member can be adjusted along the extension direction of the positioning hole 6. A reserved gap (not shown in the figure) is provided between the bottom plate 3 and the door inner panel 200, and the size of the reserved gap is 0-1mm.
[0044] Specifically, the door lock reinforcement device is positioned by a positioning member, and the positioning member passes through the positioning holes 6 on the door inner panel 200 and the first side panel 1 in sequence, and can be adjusted along the extension direction of the positioning holes 6. Therefore, the door lock reinforcement device can be adjusted relative to the door inner panel 200 along the extension direction of the positioning holes 6, thereby adjusting the size of the reserved gap between the bottom plate 3 and the door inner panel 200. The reserved gap is a gap reserved for the glue coating on the bottom plate 3. By setting the reserved gap, the thickness of the glue coating can be adjusted, the ability of the glue coating to fill the space between the bottom plate 3 and the door inner panel 200 is improved, and the filling uniformity is improved, thereby ensuring the gluing effect. In a specific embodiment, the size of the reserved gap may include 0.5 mm, and 0.5 mm is the thickness of the glue after being flattened in the embodiment of the present application. By setting a reserved gap of 0.5 mm, the glue can be evenly and completely filled between the bottom and the door inner panel 200, the adhesion is improved, and the glue cost is reduced. In another specific embodiment, the size of the reserved gap may also include other sizes within 0-1mm, such as 0.4mm, 0.45mm, 0.55mm, 0.6mm, etc., which is specifically set according to the thickness of the glue. In other embodiments, the size of the reserved gap may also be greater than 1mm to adjust the thickness of the glue to a range greater than 1mm.
[0045] Furthermore, the vehicle further comprises a door outer panel, which is connected and fixed to the door inner panel 200 , and covers a portion of the door inner panel 200 on a side away from the bottom plate 3 corresponding to the welding area 31 on the bottom plate 3 .
[0046] Specifically, the door outer panel is connected and fixed to the side of the door inner panel 200 away from the bottom plate 3, and the bottom plate 3 is welded to the door inner panel 200 through the welding area 31. A welding pit will be formed on the side of the door inner panel 200 away from the bottom plate 3 corresponding to the welding area 31, and the door outer panel covers the pit so that the pit will not be exposed on the side of the door inner panel 200 away from the bottom plate 3, thereby beautifying the appearance of the door inner panel 200.
[0047] It should be noted that the terms "horizontal", "vertical" and the like do not mean that the components are absolutely horizontal or vertical, but can be slightly tilted; the terms "parallel", "vertical" and the like do not mean that the components are absolutely parallel or vertical, but can form a certain angle deviation. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In addition, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the present application is usually placed when used, which is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.
[0048] It is to be understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless there is a special limitation. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. The term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.
[0049] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
