Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to an easy-to-form interior door panel. Background Technology

[0002] In the automotive manufacturing industry, door interior panels, as important interior components, are typically made of plastic and molded using injection molding. To ensure a secure connection between the interior panel and the vehicle body, several mounting points are simultaneously formed on the inner surface of the panel during molding, and fixing clips are installed at these points. During installation, the panel is secured to the vehicle body using the fixing clips on the back of the panel.

[0003] However, existing technologies have many problems. On the one hand, if the mounting point design is unreasonable, even if the interior panel can be fixed to the vehicle body, it will still wobble, seriously affecting the texture and user experience of the interior panel. On the other hand, taking the commonly used D-type snap-fit ​​mounting structure as an example, during its integral molding process with the interior panel, the molding and demolding of the snap-fit ​​mounting structure is greatly affected by the molding surface of the interior panel. When the molding surface of the interior panel around the D-type snap-fit ​​mounting structure is open, demolding is relatively easy; however, when the molding surface is closed, the D-type snap-fit ​​mounting structure cannot be demolded after molding. In this case, either the mounting point of the interior panel must be redesigned, which not only greatly increases the difficulty of product design and affects molding efficiency, but may also change the overall structure of the interior panel; or a suboptimal mounting point is chosen to mold the D-type snap-fit ​​mounting structure, resulting in a decrease in the installation stability of the interior panel. In addition, in the design process of the door interior panel, it is necessary to consider both the front styling design and the back mounting point design. Since the two often conflict, in order to meet the front styling requirements, the back mounting position is often designed in a secondary position, which in turn affects the texture and stability of the interior panel after installation. Utility Model Content

[0004] The present invention aims to provide an easy-to-form car door interior panel to reduce the conflict between the front styling design and the rear mounting point design, thereby reducing the difficulty of interior panel design.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an easily moldable interior door panel, comprising an interior panel body and a D-shaped buckle mounting structure, wherein an mounting position is provided on the back of the interior panel body, and the D-shaped buckle mounting structure comprises an mounting part and a fastening part, wherein the mounting part is fixed in the mounting position and integrally formed with the interior panel body, and the fastening part is detachably fixed on the mounting part and can be fixedly connected to the vehicle body.

[0006] The beneficial effects of this solution are as follows: This solution converts the D-type buckle mounting structure fixed on the interior panel body into a split type, which is formed separately and then assembled. This reduces the requirements for the D-type buckle mounting structure during the design process, thereby reducing the conflict between the front styling design and the back mounting point design, and reducing the design difficulty.

[0007] In addition, the split D-type buckle installation structure allows users to purchase the buckle separately and install it onto the interior panel body when the buckle is damaged, thereby reducing the cost and difficulty of maintenance.

[0008] Furthermore, the fastening part includes an integrally formed snap-fit ​​part and a mounting plate. The snap-fit ​​part is used to snap-fit ​​with the vehicle body. The mounting plate is provided with several positioning holes. The mounting part includes several positioning posts. One end of the positioning post is fixedly connected to the back of the interior panel. The positioning post is adapted to the positioning hole.

[0009] Beneficial effects: The design of the positioning pins and positioning holes makes the installation of the fastening parts more precise and the subsequent assembly efficiency higher.

[0010] Furthermore, the mounting section also includes reinforcing ribs, which are fixedly installed on the back of the interior trim panel and connected to the positioning post. The reinforcing ribs ensure a more stable connection between the positioning post and the interior trim panel body.

[0011] Furthermore, the top surface of the reinforcing rib forms a mounting surface that fits the mounting plate. This mounting surface design ensures that the bottom surface of the mounting plate adheres closely to the mounting surface, resulting in a higher degree of fit between the mounting plate and the mounting part, and a more secure connection between the assembled fastener and the interior trim panel body.

[0012] Furthermore, several connecting ribs are provided between the snap-fit ​​part and the mounting plate. One end of each connecting rib is fixedly connected to the snap-fit ​​part, and the other end is fixedly connected to the mounting plate. By using these connecting ribs, the designer can freely adjust the distance between the snap-fit ​​part and the mounting plate.

[0013] Furthermore, from the snap-fit ​​part to the mounting plate, the spacing between adjacent connecting ribs gradually increases. Attached Figure Description

[0019] The basic implementation examples are as follows: Figure 1-2 As shown, Figure 1-2 The image shows an easy-to-mold door interior panel, such as... Figure 1 As shown, the interior panel body 1 and the D-type snap-fit ​​mounting structure are included. The back of the interior panel body 1 is provided with a mounting position. The D-type snap-fit ​​mounting structure includes a mounting part and a fastening part. The mounting part includes a reinforcing rib 211 and a positioning post 212. The reinforcing rib 211 and the positioning post 212 are both fixed to the back of the interior panel body 1 and integrally formed with the interior panel body 1. The upper surface of the reinforcing rib 211 forms a mounting surface.

[0020] The fastening part includes a snap-fit ​​part 221, a mounting plate 23, and a connecting rib 222. The snap-fit ​​part 221 is used to snap-fit ​​with the vehicle body. The mounting plate 23 is provided with a plurality of positioning holes 231, which are adapted to the positioning post 212. The lower surface of the mounting plate 23 is adapted to the mounting surface. The connecting rib 222 is provided between the snap-fit ​​part 221 and the mounting plate 23. From the snap-fit ​​part 221 to the mounting plate 23, the spacing between adjacent connecting ribs 222 gradually increases, forming a cone structure that is smaller at the top and larger at the bottom.

[0021] During assembly, such as Figure 2 As shown, first, the positioning hole 231 of the mounting plate 23 is aligned with the positioning post 212, and the lower surface of the mounting plate 23 is placed on the mounting surface formed by the reinforcing rib 211. Then, the mounting plate 23 is fixedly connected to the mounting part by hot riveting welding or screw connection.
