[0012] A second rear door trim strip is installed over the first rear door trim strip, and the second rear door trim strip surrounds the speaker cover;

[0013] The upper decorative border is equipped with positioning buckles.

[0014] According to one embodiment of the present invention, a snap-fit ​​plate is provided on the surface of the inner panel of the rear door decorative frame, and the snap-fit ​​plate snaps onto and adheres to the rear door sealing strip and the rear door opening sealing strip.

[0015] According to one embodiment of the present invention, the cross section of the rear door sealing strip has a compression ring hole.

[0016] According to one embodiment of the present invention, the bottom of the aforementioned rear door opening sealing strip is provided with two superimposed compression ring holes, and the upper side is provided with a C-shaped retaining ring, the back of which is provided with a curved lip.

[0017] According to one embodiment of the present invention, the lower inner wall of the C-shaped retainer is provided with multiple oblique teeth, and the upper inner wall is provided with a buckle, and both are inclined inward and intersect.

[0018] According to one embodiment of the present invention, the space between the rear door panel and the upper decorative frame is filled with polyester sponge.

[0019] According to one embodiment of the present invention, the first rear door decorative strip and the second rear door decorative strip are selected from decorative strips of different colors.

[0020] Compared with the prior art, the present invention can achieve the following technical effects:

[0021] By dividing the inner panel of the rear door decorative frame into a side decorative frame and an upper decorative frame, and then bonding the rear door sealing strip and the rear door opening sealing strip respectively, the assembly sealing stability is enhanced; at the same time, two kinds of rear door decorative strips are installed on the rear door guard plate to surround the speaker cover, enhancing the decorative aesthetics and improving functionality.

[0027] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the sealing assembly structure of the automotive rear door decorative frame according to an embodiment of the present invention.

[0029] As shown in the figure, a sealing assembly structure for a car rear door trim frame includes: an inner panel 10 of the rear door trim frame, the inner panel 10 having a side trim frame 11 and an upper trim frame 12 that are bent and connected; a rear door sealing strip 20 adhered to the side trim frame 11; a rear door opening sealing strip 30 adhered to the upper trim frame 12 and close to the rear door sealing strip 20; a rear door guard plate 40 disposed on the upper trim frame 12 and located outside the rear door opening sealing strip 20; a first rear door trim strip 50 installed on the upper side of the rear door guard plate 40; a speaker cover 60 disposed on the first rear door trim strip 50; and a second rear door trim strip 70 covering the first rear door trim strip 50, the second rear door trim strip 70 surrounding the speaker cover 60; wherein, the upper trim frame 12 is provided with a positioning buckle 80.

[0030] In one embodiment of the present invention, the rear door decorative inner frame 10 is the window frame of the rear door of a car, and is curved. Its cross-section consists of a bent and connected side decorative frame 11 and an upper decorative frame 12. The side decorative frame 11 is bonded with a rear door sealing strip 20 to abut against the inner side of the car door sheet metal, while the upper decorative frame 12 is bonded with a rear door opening sealing strip 30 to abut against the upper side of the car door sheet metal. This achieves bidirectional pressure, enhancing the buffering and sealing effect, resulting in better tightness and stronger stability when the door window frame is closed. The rear door guard plate 30 is installed and fixed to the rear side of the upper decorative frame 12 to improve strength and decorative effect.

[0031] The first rear door trim strip 50 is installed on the surface of the rear guard plate 30 to form a decorative layer. The speaker cover 60 is installed at the door frame to improve functionality. Part of it needs to connect to the rear door guard plate 30. Therefore, a sufficient area is reserved at the edge of the first rear door trim strip 50, and then the second rear door trim strip 70 is continued to cover it to form the edge of the speaker cover 60, which enhances the aesthetic transition effect and improves functionality.

[0032] The upper decorative frame 12 of the present invention is provided with a positioning buckle 80, which is used to fasten and fix it to the corresponding position of the car door to maintain stability and make assembly more convenient.

[0033] In addition, a snap-fit ​​plate 90 is provided on the surface of the inner panel 10 of the rear door decorative frame. The snap-fit ​​plate 90 snaps and adheres the rear door sealing strip 20 and the rear door opening sealing strip 30 to form an inner lining, strengthen the connection effect, improve impact resistance, and enhance the strength and service life of the inner panel 10 of the rear door decorative frame.

[0034] In a preferred embodiment, the rear door sealing strip 20 has a compression ring hole in its cross section to enhance cushioning and improve sealing performance.

[0035] The rear door opening sealing strip 30 has two overlapping compression ring holes 31 at its bottom to enhance the impact resistance of the upper part. In addition, a C-shaped retaining ring 32 is provided on the upper side to align with the interface of the upper sheet metal of the door, improving the sealing effect. The back of the C-shaped retaining ring 32 has a curved lip 33 to enhance water resistance.

[0036] Furthermore, the lower inner wall of the C-shaped retaining ring 32 is provided with multiple oblique teeth, and the upper inner wall is provided with a reverse buckle. Both are inclined inward and intersect to form a snap-on seal, which can fully compress the interface of the upper sheet metal of the car door to ensure a seal.

[0037] The rear door guard plate 40 and the upper decorative frame 12 of the present invention are filled with polyester sponge to enhance the sound absorption effect.

[0038] Preferably, the first rear door trim strip 50 and the second rear door trim strip 70 are selected from trim strips of different colors to enhance the aesthetics.

[0039] In summary, this invention strengthens assembly and sealing stability by dividing the inner panel of the rear door decorative frame into a side decorative frame and an upper decorative frame, and then bonding the rear door sealing strip and the rear door opening sealing strip to them respectively; at the same time, the rear door guard plate is equipped with two kinds of rear door decorative strips to surround the speaker cover, enhancing the decorative aesthetics and improving functionality.

[0040] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
