However, due to the limitation of the rotation installation, the positioning buckle needs to be installed on the door guard in the front-to-back direction. After the door guard and the door sheet metal are installed, the positioning of the positioning buckle and the door guard in the front-to-back direction is easy to fail, causing the door guard to move forward and backward relative to the door sheet metal, thereby affecting the gap surface difference of the assembly. Utility Model Content

[0003] In view of this, the present application provides a door guard plate flip-up installation structure and a vehicle door assembly, which can prevent the door guard plate from moving forward and backward relative to the vehicle door sheet metal.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] like Figure 1-Figure 6 As shown, an embodiment of the present application provides a door guard plate flip-up installation structure, including a vehicle door sheet metal 2, a door guard plate 1, a positioning assembly and a limit assembly.

[0037] The door guard panel 1 is connected to the vehicle door sheet metal 2. Specifically, during the connection process, the upper side of the door guard panel 1 is first hung on the vehicle door sheet metal 2, and then the door guard panel 1 is flipped downward relative to the vehicle door sheet metal 2, and finally the door guard panel 1 is buckled with the vehicle door sheet metal 2.

[0038] The positioning assembly is arranged on the door sheet metal 2 and the door guard plate 1. During the connection process, when the door guard plate 1 is turned downward relative to the door sheet metal 2, the positioning assembly is used to position the door guard plate 1 and the door sheet metal 2 to ensure that the positions of the door guard plate 1 and the door sheet metal 2 are accurate. At the same time, after the door guard plate 1 and the door sheet metal 2 are connected, the positioning assembly can limit the displacement of the door guard plate 1 relative to the door sheet metal 2 along the first direction. Specifically, the first direction is set to the up and down direction of the door sheet metal 2.

[0039] The limiting assembly is arranged on the door sheet metal 2 and the door guard plate 1. When the door guard plate 1 is not connected to the door sheet metal 2, the limiting assembly does not work. After the door guard plate 1 is connected to the door sheet metal 2, the limiting assembly works and limits the displacement of the door guard plate 1 relative to the door sheet metal 2 along the second direction. Since the first direction forms an angle with the second direction, for example, the first direction is set to the up-down direction, and the second direction is set to the front-back direction, the position of the door guard plate 1 and the door sheet metal 2 can be limited in two different directions. The two directions restrict each other, thereby preventing the door guard plate 1 from moving forward and backward relative to the door sheet metal 2, improving the installation stability, and ensuring the assembly gap surface difference of the structure.

[0040] In this way, a limit assembly is introduced to limit the displacement of the door guard plate 1 relative to the door sheet metal 2 along the second direction, and the first direction and the second direction form an angle, thereby preventing the door guard plate 1 from moving forward and backward relative to the door sheet metal 2, thereby improving the installation stability and ensuring the assembly gap surface difference of the structure.

[0041] In some embodiments, the limiting assembly includes a limiting protrusion 15 and a limiting notch 21. The limiting notch 21 can be set in the form of a limiting groove or a limiting hole. The positions of the limiting protrusion 15 and the limiting notch 21 match so that the limiting protrusion 15 can extend into the limiting notch 21. Among them, the limiting protrusion 15 is set on the door guard plate 1, and the limiting notch 21 is set on the vehicle door sheet metal 2, which is conducive to ensuring that the surface of the door guard plate 1 is smooth without protruding edges and corners, thereby making the surface of the vehicle door beautiful. Alternatively, the limiting protrusion 15 is set on the vehicle door sheet metal 2, and the limiting notch 21 is set on the door guard plate 1. When the door guard plate 1 is connected to the vehicle door sheet metal 2, the limiting protrusion 15 is located in the limiting notch 21, and the limiting protrusion 15 and the limiting notch 21 abut in the second direction. For example, the two side walls of the limiting protrusion 15 in the second direction abut against the two side walls of the limiting notch 21 in the second direction to limit the position in the second direction. In this way, the limiting component is simple and reliable, has strong stability and is easy to process.

[0042] like Figure 5 , 6As shown, the limiting protrusion 15 includes a boss and a plurality of reinforcing ribs. The boss is connected to the door guard plate 1. Each reinforcing rib is connected to the door guard plate 1 and the boss. The connection of the boss can be strengthened by the plurality of reinforcing ribs, thereby improving the structural stability of the boss. Specifically, the boss and the reinforcing ribs are integrally formed on the door guard plate 1. Two reinforcing ribs are respectively provided on both sides of the boss in the second direction, so that support can be provided in the second direction of the boss, further improving the stability of the limiting function and the limiting effect.

[0043] In the specific solution, four reinforcing ribs are provided and are respectively located in four directions of the protruding column, of which two reinforcing ribs are respectively located on both sides of the protruding column in the first direction, and the other two reinforcing ribs are respectively located on both sides of the protruding column in the second direction. In this way, the protruding column is supported in multiple directions by multiple reinforcing ribs, so that the limiting protrusion 15 has better stability.

[0044] It is understandable that, since both the convex column and the reinforcing rib constitute a part of the limiting protrusion 15, the convex column or the reinforcing rib can be used to abut against the side wall of the limiting notch 21. Here, it is preferred that the reinforcing rib abuts against the side wall of the limiting notch 21, and the height of the reinforcing rib is consistent with the height of the convex column, so that the limiting protrusion 15 forms a cross column shape.

[0045] The limiting notch 21 is configured to be strip-shaped and extends along a first direction (i.e., the up and down direction). During the flipping of the door guard plate 1 relative to the door sheet metal 2, the limiting protrusion 15 can gradually extend into the limiting notch 21. The strip-shaped design of the limiting notch 21 allows for avoidance during the embedding of the limiting protrusion 15, which is beneficial for achieving the insertion and extension of the limiting protrusion 15.

[0046] In some embodiments, the door guard plate 1 is connected to the door sheet metal 2 through a positioning assembly, and the limiting assembly is close to the positioning assembly. In this way, the working positions of the positioning assembly and the limiting assembly are close, which is conducive to forming a limiting effect in the second direction and the first direction to interfere with each other, enhance the limiting effect, and ensure a better gap surface difference in the assembly.

[0047] Wherein, the positioning assembly includes a main positioning buckle 11 and an auxiliary positioning buckle 12. Both the main positioning buckle 11 and the auxiliary positioning buckle 12 are connected to the door guard plate 1 and are clamped with the door sheet metal 2, wherein the main positioning buckle 11 is closer to the opening and closing axis of the door sheet metal 2 relative to the auxiliary positioning buckle 12. Here, the opening and closing axis of the door sheet metal 2 is located at the front side of the door sheet metal 2, and is used to connect with the vehicle body to realize the opening and closing of the door relative to the vehicle body. Specifically, the main positioning buckle 11 is connected to the front of the door guard plate 1 and is clamped with the door sheet metal 2. The auxiliary positioning buckle 12 is connected to the rear of the door guard plate 1 and is clamped with the door sheet metal 2. During the installation process of the door guard plate 1, the main positioning buckle 11 and the auxiliary positioning buckle 12 are first connected to the front and rear of the door guard plate 1 respectively, and then the main positioning buckle 11 and the auxiliary positioning buckle 12 are driven close to the door sheet metal 2 through the door guard plate 1, so that the main positioning buckle 11 and the auxiliary positioning buckle 12 are connected to the front and rear of the door sheet metal 2 respectively.

[0048] The limiting component is close to the main positioning buckle 11. Since the main positioning buckle 11 mainly plays a positioning role, it can limit the displacement of the door guard plate 1 relative to the door sheet metal 2 along the first direction. The positioning component and the main positioning buckle 11 have similar action positions, which is conducive to the formation of limiting effects in the second direction and the first direction. Interference with each other, enhances the limiting effect, and ensures a better gap surface difference in assembly.

[0049] Here, the main positioning buckle 11 and the auxiliary positioning buckle 12 are both arranged above the door guard plate 1. During the installation process of the door guard plate 1, the main positioning buckle 11 and the auxiliary positioning buckle 12 are driven by the door guard plate 1 to approach the door sheet metal 2. The main positioning buckle 11 and the auxiliary positioning buckle 12 first contact the door sheet metal 2, which has a better positioning effect.

[0050] The front of the door guard 1 is provided with a first card slot 13 for connecting the main positioning buckle 11, and the opening of the first card slot 13 faces backward, so that the main positioning buckle 11 can be extended into the first card slot 13 from the back to the front, thereby realizing the connection between the main positioning buckle 11 and the door guard 1. The rear of the door guard 1 is provided with a second card slot 14 for connecting the auxiliary positioning buckle 12, and the opening of the second card slot 14 faces forward, so that the auxiliary positioning buckle 12 can be extended into the second card slot 14 from the front to the back, thereby realizing the connection between the auxiliary positioning buckle 12 and the door guard 1. In this way, the opening directions of the first card slot 13 and the second card slot 14 are arranged in opposite directions, which is conducive to preventing the main positioning buckle 11 and the auxiliary positioning buckle 12 from being separated from the door guard 1, thereby improving the structural stability.

[0051] The embodiment of the present application provides a vehicle door assembly, including a door guard flip installation structure, which is the door guard flip installation structure in the above embodiment. In this way, by introducing a limit assembly to limit the displacement of the door guard 1 relative to the vehicle door sheet metal 2 along the second direction, the first direction and the second direction form an angle, thereby preventing the door guard 1 from moving forward and backward relative to the vehicle door sheet metal 2, improving the installation stability, and ensuring the assembly gap surface difference of the structure.

[0052] It should be noted that the description of the front, back, up, and down directions in this article is based on the front, back, up, and down directions of the door assembly, door guard plate 1, and door sheet metal 2 when the door assembly is installed on the vehicle. The front is the direction close to the front of the vehicle, the rear is the direction close to the rear of the vehicle, the top is the direction close to the roof, and the bottom is the direction close to the bottom of the vehicle.
