Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a door triangle plate mounting structure and an automobile. Background Technology

[0002] The inner triangular panel in a car door is a decorative interior component, primarily serving to conceal the sheet metal structure, enhance the interior aesthetics, and prevent occupants from directly contacting the vehicle's sheet metal. Traditionally, the inner triangular panel is mounted on the sheet metal, connected via locking points, with corresponding mating holes stamped into the sheet metal. However, limitations in sheet metal stamping processes prevent the creation of effective limiting structures, resulting in a lack of reliable mounting points and making it difficult to maintain proper clearance between the inner triangular panel and surrounding components. Summary of the Invention

[0003] To address the problem that the installation of the inner triangular plate in the car door is limited by the sheet metal stamping process, making it impossible to manufacture an effective limiting structure, resulting in an unreliable installation structure and difficulty in ensuring the gap between the inner triangular plate and the surrounding parts.

[0004] This application provides a door triangular plate mounting structure, including an inner triangular plate and a door interior panel; the inner triangular plate is provided with at least one set of side connectors on the side facing the door interior panel, and the door interior panel is provided with a side mounting part;

[0005] The side connector includes a limiting member and a snap-fit ​​member, and the side assembly includes a limiting hole adapted to the limiting member and a snap-fit ​​hole connected to the snap-fit ​​member;

[0006] The inner triangular plate has a mounting bracket on the side facing the door sheet metal, and the mounting bracket is connected to the door interior panel.

[0007] Furthermore, the interior door panel is provided with an inner protective panel, and the inner protective panel is provided with a hook-up part, and the hook-up piece is connected to the hook-up part.

[0008] Furthermore, the limiting element is a strip-shaped element.

[0009] Furthermore, the snap-fit ​​component is provided with a snap hook, and the snap-fit ​​hole is provided with a snap fastener that connects to the snap hook.

[0010] Furthermore, the spacing between two adjacent sets of side connectors is 65mm-85mm.

[0011] Furthermore, the inner triangular plate has at least one supporting rib on the side facing the door sheet metal, and the supporting rib abuts against the door sheet metal.

[0012] Furthermore, the door interior trim panel and the inner protective panel are integrally formed.

[0013] Furthermore, the inner protective panel is provided with a mounting component, and the door sheet metal is provided with a mounting fitting component that connects to the mounting component.

[0014] Furthermore, the mounting component is a mounting hole, the mounting mating component is a locking seat, and the mounting component and the mounting mating component are connected by fasteners.

[0015] This application also provides an automobile, including the aforementioned door triangular plate mounting structure.

[0016] Implementing the embodiments of the present invention has the following beneficial effects:

[0017] (1) The inner triangular plate of this application is connected to the interior panel of the car door. The side and inner side of the inner triangular plate are respectively provided with side connectors and hooks to connect to the interior panel of the car door from different directions, which reduces the surface difference between the inner triangular plate and the interior panel of the car door, improves the matching gap between the inner triangular plate and the surrounding parts, and reduces the difficulty of stamping the car door sheet metal.

[0018] (2) An inner guard plate is provided on the interior panel of the door in this application. The inner guard plate is connected to the body sheet metal, which increases the strength of the installation structure. The hook on the inner side of the inner triangle plate is connected to the inner guard plate. The two structural contact surfaces will generate a tension force on the hook, which plays a role in restraining the displacement of the inner triangle plate, so that the inner triangle plate fits better with the door sheet metal.

[0019] (3) Both the inner triangular plate and the door interior panel of this application are injection molded parts. Compared with stamped parts, they can achieve more complex structural features. Therefore, there are more side connecting parts between the inner triangular plate and the door interior panel, the limiting structure is more complex and reliable, and the gap with the side door glass, water cutter and other peripheral parts is easier to guarantee.

[0033] Example

[0034] like Figure 1-5 As shown, this embodiment provides a door triangular plate mounting structure, including an inner triangular plate 1 and a door interior panel 2; at least one set of side connectors 11 are provided on the side of the inner triangular plate 1 facing the door interior panel 2, and a side mounting part 21 connected to the side connectors 11 is provided on the door interior panel 2.

[0035] Specifically, the side connector 11 includes a limiting member 111 and a snap-fit ​​member 112, and the side assembly part 21 includes a limiting hole 211 adapted to the limiting member 111 and a snap-fit ​​hole 212 connected to the snap-fit ​​member 112.

[0036] Specifically, the inner triangular plate 1 is provided with a hook 12 on the side facing the door sheet metal 3, and the hook 12 is connected to the door interior panel 2.

[0037] In this embodiment, the limiting member 111 can be a strip-shaped member. In some embodiments, the limiting member 111 can be a strip-shaped sheet or a columnar member. Preferably, it can be a strip-shaped columnar member. In some embodiments, the diameter of the columnar member gradually decreases along the end facing the limiting hole 211. The limiting member 111 is inserted into the limiting hole 211 to prevent the inner triangular plate 1 from moving to one side, thereby controlling the surface difference between the inner triangular plate 1 and the door interior panel 2. The snap-fit ​​member 112 is provided with a hook 1121, and the snap-fit ​​hole 212 of the door interior panel 2 is provided with a fastener connected to the hook 1121. In some embodiments, the fastener can be a metal clip or a metal snap-fit ​​piece disposed in the snap-fit ​​hole 212. The snap-fit ​​member 112 is connected to the snap-fit ​​buckle 212, which serves as a connection and fastening function to control the gap between the inner triangular plate 1 and the door interior panel 1.

[0038] In this embodiment, the limiting member 111 and the snap-fit ​​member 112 of the side connector 11 are used in combination, and the interval between two adjacent sets of side connectors 11 is 65mm-85mm. Preferably, it can be 65mm, 70mm, 75mm, 80mm or 85mm. In this embodiment, four sets of side connectors 11 are spaced apart on the side of the inner triangular plate 1 facing the door interior panel 2, and the distance between two adjacent sets of side connectors 11 is 70mm. The combination of the limiting member 111 and the snap-fit ​​member 112 in this embodiment simultaneously ensures the surface difference and gap value between the inner triangular plate 1 and the door interior panel 2, and the connection limiting points are spaced apart, with more points and a more reliable connection.

[0039] It should be noted that in practical applications, the inner triangular plate 1 and the door interior panel 2 are usually injection molded parts. Because injection molded parts can achieve more complex structural features compared to stamped parts, in this embodiment, the inner triangular plate 1 is connected to the door interior panel 2. Multiple sets of side connecting parts 11 can be set on the side of the inner triangular plate 1 according to the side length and shape, resulting in more mounting points and a more complex and reliable limiting structure. The reduced gap between the inner triangular plate 1 and the door interior panel makes it easier to ensure the gap between the inner triangular plate 1 and surrounding components such as the side door glass and water jet.

[0040] Specifically, such as Figure 6 Schematic diagram of the inner liner and Figure 7 As shown in the schematic diagram of the connection between the inner trim panel and the inner triangular plate, in this embodiment, the door interior trim panel is provided with an inner trim panel 22, and the inner trim panel 22 is provided with a hook part 221, and the hook part 12 is connected to the hook part 221. Preferably, the hook part 12 is located in the middle of the inner triangular plate 1, the hook part 12 is bent downward, and the hook part 221 is bent upward relative to the hook part 12. When the hook part 12 is hooked together with the hook part 221 of the door interior trim panel 2, the two structural contact surfaces will generate a tension force on the hook part 12, which plays a role in restraining the displacement of the inner triangular plate 1, so that the inner triangular plate 1 and the inner trim panel 22 are in close contact without gaps, the gap between the inner triangular plate 1 and the door sheet metal 3 is reduced, and the surface difference between the inner triangular plate 1 and the door interior trim panel 2 is reduced. Preferably, the gap between the inner triangular plate 1 and the door sheet metal 3 is less than 5mm. The reduction of the gap between the inner triangular plate 1 and the door sheet metal 3 helps to avoid abnormal noises from the door. Specifically, the door interior trim panel 2 and the inner trim panel 22 are integrally formed. In practical applications, the door interior panel 2 is usually an injection molded part, so the inner trim panel 22 can be integrally injection molded with the door interior panel 2. The overall structure of the door interior panel 2 is stronger.

[0041] Specifically, such as Figure 8As shown, the inner protective plate 22 is provided with a mounting part 222, and the door sheet metal 3 is provided with a mounting fitting part 31 that connects to the mounting part 222. In this embodiment, the mounting part 222 is a mounting hole, and the mounting fitting part 31 is a locking seat. The mounting part 222 and the mounting fitting part 31 are connected by fasteners. The fasteners can be rivets, screws, bolts, or other connecting fasteners. In this embodiment, the inner triangular plate 1 is connected to the inner protective plate 22, and the connection between the inner protective plate 22 and the door sheet metal 3 increases the strength of the installation structure and improves the assembly reliability.

[0042] Specifically, in this embodiment, at least one support rib 13 is provided on the side of the inner triangular plate 1 facing the door sheet metal 3, and the support rib 13 abuts against the door sheet metal 3. In practical applications, the support rib 13 is integrally injection molded with the inner triangular plate. In some embodiments, the number of support ribs 13 is at least two. In other embodiments, the support ribs 13 are distributed at the three corners and the middle of the inner triangular plate 1. The support ribs 13 are used to prevent the inner triangular plate from deforming under pressure and to increase the rigidity of the inner triangular plate surface.

[0043] This embodiment also provides an automobile, including a door triangular plate mounting structure.

[0044] Specifically, in this embodiment, the inner guard plate 22 of the door interior panel 2 is connected to the door sheet metal 3, and the inner triangular plate is stacked on the inner guard plate 22, with the side of the inner triangular plate 1 facing the door interior panel 2 facing downwards. The triangular plate mounting structure is assembled and installed from top to bottom. First, the back hook 12 of the inner triangular plate 1 is connected to the hook part 221 on the inner guard plate 22; then, the side limiting piece 111 is inserted into the limiting hole 211, and at the same time, the snap-fit ​​piece 112 is snap-fitted into the snap-fit ​​hole 212 to adjust the gap between the side of the inner triangular plate 1 and the door interior panel 2; finally, the outer surface of the inner triangular plate 1 is pressed to adjust the surface difference between the inner triangular plate 1 and the door interior panel.

[0045] The inner triangular plate of this application is connected to the door interior panel. Side connecting parts and hook parts are respectively provided on the side and inner side of the inner triangular plate to connect to the door interior panel from different directions, which reduces the surface difference between the inner triangular plate and the door interior panel, improves the matching gap between the inner triangular plate and the surrounding parts, and reduces the difficulty of door sheet metal stamping.

[0046] This application provides an inner protective panel on the interior door panel, which is connected to the body sheet metal, increasing the strength of the installation structure. The hook on the inner side of the inner triangular plate is connected to the inner protective panel, and the contact surfaces of the two structures will generate a tension force on the hook, which will constrain the displacement of the inner triangular plate and make the inner triangular plate fit more closely to the door sheet metal.

[0047] Both the inner triangular plate and the door trim panel in this application are injection molded parts, which allow for more complex structural features compared to stamped parts. Therefore, the number of side connectors between the inner triangular plate and the door trim panel is greater, the limiting structure is more complex and reliable, and the gaps with peripheral components such as the side door glass and water jet are reduced. The installation structure of the door triangular plate in this application is simpler, more reliable, and lower in cost.

[0048] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
