Description

Technical Field

[0001] This utility model belongs to the technical field of automotive door interior parts, specifically, it relates to an upper decorative panel for automotive rear doors. Background Technology

[0002] In automotive interior design and manufacturing, door trim panels are a crucial component. They not only serve a decorative purpose but also must meet certain structural strength and assembly requirements to ensure the stability and safety of the vehicle during operation. Among these, the rear door trim panel is a key part, and its structural design directly impacts the overall quality and usability of the door interior.

[0003] Currently, most common automotive rear door trim panels on the market use a single panel structure or only have a few simple fixing structures on the back of the panel. This type of design has many shortcomings: First, the edges of the panel lack effective protection and support structures, making them prone to deformation and damage after long-term use, especially the upper bending parts, which are easily broken when subjected to external impacts; second, the fixing structure design is unreasonable. For example, when using simple buckle connections, the buckles are prone to loosening and falling off, resulting in unstable installation of the trim panel and affecting the user experience; in addition, some trim panels do not have dedicated reinforcement structures, resulting in low overall structural strength. They cannot effectively withstand the assembly pressure of internal door components and also lack cushioning performance. When the car vibrates during driving, they are prone to colliding with other door components, producing abnormal noises, or even damaging related components.

[0004] To address the problems existing in the prior art, this utility model proposes a car rear door decorative upper panel with a reasonable structural design, stable installation, high strength, and good buffering performance. Utility Model Content

[0005] In view of this, the technical problem to be solved by this utility model is to provide a car rear door trim panel to avoid the defects of previous car rear door trim panels, such as low structural strength, unstable installation and poor cushioning performance.

[0006] To solve the above-mentioned technical problems, this utility model discloses a decorative upper panel for the rear door of an automobile: The rear door trim panel includes a main body with a rearward-bent curved edge on the upper side and rearward-folded edge banding on the left, right, and lower sides. The curved edge banding design allows the main body to better fit the curved structure of the rear door, improving the fit of the assembly; the edge banding on the left, right, and lower sides protects the edges of the main body, preventing edge wear and enhancing the overall structural stability of the main body.

[0007] Three U-shaped buckles are provided on the back of the curved edge. The U-shaped buckles are used to quickly connect the upper decorative panel to the sheet metal of the rear door of the car. The three U-shaped buckles can ensure the uniformity and stability of the connection and prevent the upper decorative panel from becoming loose on one side during use.

[0008] The back of the curved edge is also covered with a reinforcing liner. The upper surface of the reinforcing liner has multiple buffer ribs that support the curved edge. These buffer ribs can cushion the curved edge when the vehicle vibrates, reducing the impact of vibration on the decorative panel and preventing abnormal noise or damage. The reinforcing liner also has recessed square holes corresponding to the U-shaped buckle. These recessed square holes have protrusions that abut against the opposite ends of the U-shaped buckle. The protrusions can limit and fix the U-shaped buckle, preventing it from shifting after installation and further improving the stability of the U-shaped buckle connection. The reinforcing liner also has three downwardly extending positioning supports with positioning round holes. The cooperation between the positioning supports and the positioning round holes can provide precise positioning for the assembly of the reinforcing liner and the panel body, ensuring that the reinforcing liner is accurately installed on the back of the panel body.

[0009] A positioning post is provided on the back of the panel body at the position corresponding to the positioning hole. The positioning post and the positioning hole cooperate with each other. When assembling the reinforcing liner, the positioning post is inserted into the positioning hole to quickly achieve the positioning and installation of the reinforcing liner, improve assembly efficiency, and at the same time ensure that the relative position between the reinforcing liner and the panel body is fixed, avoiding displacement during use.

[0010] The back of the panel body is also provided with multiple reinforcing ribs and screw mounting holes. The multiple reinforcing ribs can significantly improve the structural strength of the panel body and prevent the panel body from deforming during long-term use. The screw mounting holes are used to fix the upper trim panel to other parts of the car rear door with screws, further enhancing the stability of the upper trim panel installation. Together with the U-shaped buckle, double fixing is achieved to ensure that the upper trim panel remains stable during the car's movement.

[0011] Furthermore, the reinforcing liner is provided with downwardly folded positioning edges on both the inner and outer sides, and the inner positioning edge abuts against a portion of the reinforcing ribs. The positioning edges further limit the installation position of the reinforcing liner on the back of the panel body. Simultaneously, the abutment between the inner positioning edge and the reinforcing ribs ensures a tighter connection between the reinforcing liner and the panel body, enhancing the overall structural stability and transferring the force borne by the reinforcing liner to the reinforcing ribs, thus improving the overall structural load-bearing capacity.

[0012] Furthermore, the panel body has handle mounting holes for installing door handles. The handle mounting holes allow the trim panel to integrate door handle installation functionality without requiring additional mounting holes on the door, simplifying the door assembly process while ensuring the stability and aesthetics of the installed door handles.

[0013] Furthermore, the positioning support has raised reinforcing ridges along its edges. These reinforcing ridges enhance the structural strength of the positioning support, preventing it from breaking under stress during assembly or use, and ensuring the long-term reliability of its positioning function.

[0014] Furthermore, the panel body is covered with a leather layer. The leather layer significantly enhances the appearance and feel of the panel body, strengthens the luxurious feel of the car interior, and also provides a certain degree of wear resistance and stain resistance, facilitating daily cleaning and maintenance and extending the service life of the decorative panel.

[0015] Compared with the prior art, the present invention can achieve the following technical effects: By setting three U-shaped buckles to connect with the sheet metal parts of the car's rear door, and using the protrusion of the recessed square hole to limit the U-shaped buckles, the positioning post and positioning round hole are used to achieve precise positioning of the reinforcing liner and the main panel. In addition, the double fixation of the screw mounting hole post effectively avoids the problem of loosening and displacement after the upper decorative panel is installed, ensuring the stability of the installation.

[0016] The multiple reinforcing ribs on the back of the panel body, the reinforced lining, and the reinforced edges of the positioning support enhance the overall structural strength of the upper decorative panel from multiple aspects. This effectively withstands the assembly pressure of the internal components of the door and the vibration and impact during vehicle operation, preventing the upper decorative panel from deforming or breaking and extending its service life.

[0017] Multiple buffer ribs on the reinforced lining can effectively cushion the curved edges of the panel body when the car vibrates during driving, reducing the impact of vibration on the upper trim panel and other door components, preventing abnormal noises, and improving the user experience.

[0018] The fit between the positioning pin and the positioning hole, and the contact between the positioning edge and the reinforcing rib, provide precise positioning for the assembly of each component, simplify the assembly process, improve assembly efficiency, and reduce production costs.

[0019] The leather layer covering the main panel not only enhances the appearance and feel of the trim panel, but also improves its wear resistance and stain resistance, meeting the high-quality requirements of modern automotive interiors.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description
