[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this application, and to facilitate its implementation.

[0017] like Figures 1 to 3 As shown, the installation structure of the vehicle frame trim panel includes a door frame sheet metal 1, and a trim panel 4 comprising an outer panel 5 and an inner panel 6. One side of the inner panel 6 has a slot 7, and one side of the door frame sheet metal 1 is located within the slot 7. The other side of the inner panel 6 is detachably connected to the door frame sheet metal 1. The slot 7 creates a U-shaped cross-section on one side of the inner panel 6, allowing it to hook onto the door frame sheet metal 1. This provides positioning for subsequent screw 9 connections, improving the convenience of trim panel installation and removal. Furthermore, the operation requires no auxiliary tools or materials, resulting in lower costs.

[0018] like Figure 3As shown, the door frame sheet metal 1 includes an outer sheet metal 2 and an inner sheet metal 3. The inner panel 6 has a connecting edge 8 on the other side, which is connected to the outer sheet metal 2 by screws 9. Traditionally, door trim panels 4 rely on 3M tape for bonding and fixing. However, during long-term use, especially under extreme conditions such as high temperatures and direct sunlight, the adhesive is prone to aging and decreased adhesion, causing the edges of the trim panel 4 to lift. Tape bonding is also prone to shrinkage on the surface of the trim panel 4 due to thermal expansion and contraction or uneven adhesion, affecting the vehicle's appearance. This new design uses slots 7 and mounting screws 9 to fix the door frame to the trim panel 4, replacing the traditional method of bonding with 3M tape. The slots 7 can initially hook onto the edges of the door frame sheet metal 1, ensuring accurate installation. On this basis, mounting screws 9 are used for multi-point reinforcement. This design retains the convenience of snap-fit ​​installation while improving the stability of the connection structure through the screws 9, and solves problems such as trim panel 4 lifting under sunlight and shrinkage on the product surface causing customer complaints.

[0019] like Figure 3 As shown, a first sponge strip 11 is provided between the door frame sheet metal 1 and the inner panel 6, and a second sponge strip 12 is provided between the outer sheet metal 2 and the connecting edge 8. Screws 9 press the second sponge strip 12 together. Both sponge strips are located between the inner panel 6 and the outer sheet metal 2, which disperses the contact force and provides a cushioning effect. The first sponge strip 11 is strip-shaped and its length is adapted to the length of the inner panel 6. The second sponge strip 12 adopts a contour design and is located between the contact surfaces of the inner panel 6 and the outer sheet metal 2 after installation. The second sponge strip 12 is also provided with holes for the screws 9 to pass through, so that the second sponge strip 12 will not easily come loose after installation.

[0020] like Figure 3 As shown, the opening end of the slot 7 is horizontal. The opening end of the slot 7 faces the front end of the door, realizing the installation sequence of first hooking the decorative panel 4 with the slot 7 and then connecting it with the screw 9. During installation, the decorative panel 4 can be assembled from back to front. Since there are generally no parts obstructing the edge of the door, it is convenient for the operator to hook the panel and improve the assembly efficiency.

[0021] like Figure 3 As shown, the end of the connecting edge 8 is inclined. The above structure changes the installation direction of the screw 9, allowing the screw 9 to be offset at a certain angle relative to the outer panel 5 to avoid setting holes on the decorative panel 4, so that the installed screw 9 is not exposed on the surface of the decorative panel 4, ensuring the aesthetics of the vehicle's exterior trim.

[0022] like Figure 3 As shown, the outer panel 5 has protrusions 10 on both sides, which are engaged with the edges of the inner panel 6. The inner panel 6 and the outer panel 5 have the same shape and are fixed together by the protrusions 10. The inner panel 6 and the outer panel 5 can be pre-assembled into a whole decorative panel 4 before installation.

[0023] like Figure 1 As shown, there are multiple screws 9. Typically, three screws 9 are provided, which are respectively connected to both ends and the middle of the inner plate 6, serving to achieve a uniform connection.

[0024] The installation process for the door assembly using this frame trim panel mounting structure is as follows: The trim panel 4 is pre-assembled, and a sponge strip is fixed to the door frame sheet metal 1 or the inner side of the inner panel 6. Figure 3 As shown, the decorative panel 4 is assembled from back to front on the door frame with the opening end of the slot 7 facing outwards. The inner panel 6 is hooked onto the door frame sheet metal 1 and then installed onto the door frame sheet metal 1 using three mounting screws 9.

[0025] The installation structure of this vehicle frame trim panel utilizes slots 7 and screws 9 to facilitate the installation and removal of the trim panel. The structure is simple, reliable, and effective, and can significantly reduce costs. It replaces the use of 3M tape and can effectively solve problems such as assembly difficulties, warping due to high temperature exposure, or shrinkage on the product surface, ensuring the appearance quality of the vehicle and improving the customer's user experience.

[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
