Description

Technical Field

[0001] This utility model belongs to the field of automotive door interior technology, specifically, it relates to an integrated component for easy assembly of automotive door interior cover trim panels. Background Technology

[0002] In the automotive manufacturing industry, door interior trim panels, as a core component of the door interior, not only need to fulfill decorative functions but also meet multiple requirements such as storage, speaker installation, and structural protection. Traditional door interior trim panels typically employ a multi-part assembly structure; for example, the inner panel body, outer cover, storage box, and speaker mounting brackets must be manufactured separately and assembled one by one, which presents the following problems: Low assembly efficiency: The independent assembly of multiple parts requires multiple positioning and fixing processes, which is cumbersome. Furthermore, the accuracy of the fit between the parts depends on the control of multiple processes, which can easily lead to assembly errors, resulting in low production efficiency and increased manufacturing costs. Poor space utilization: In traditional structures, the storage compartments are scattered with other functional components (such as speakers), failing to make full use of the limited space inside the door. Moreover, the storage compartments are mostly single cavities, which cannot achieve classified storage of items, resulting in insufficient practicality. Insufficient structural stability: The joints of multiple components are prone to loosening and abnormal noise due to long-term use or vibration. In addition, some components are designed to be lightweight, which reduces the reinforcement structure, resulting in insufficient overall strength and affecting service life. Poor ease of maintenance: Repairing components such as speakers and internal door wiring requires disassembling the entire inner trim panel, which is complicated and increases the difficulty and cost of after-sales maintenance.

[0003] To address the aforementioned issues, there is an urgent need in the field for a highly integrated, easy-to-assemble, space-efficient, and easy-to-maintain door interior panel assembly to meet the automotive manufacturing industry's demands for high efficiency, low cost, and high practicality. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide an integrated component for easy assembly of the interior door cover panel, which avoids the defects of low assembly efficiency, poor space utilization, insufficient structural stability and inconvenient maintenance of the previous interior door cover panel.

[0005] To address the aforementioned technical problems, this utility model discloses a conveniently assembled integrated assembly for a car door inner cover trim panel, comprising: The main body of the inner door panel is integrally formed. The lower left side has an outwardly folded bottom plate, and the right side is set with an inward recess. The bottom plate has an upwardly extending boss. The edge of the main body of the inner door panel is provided with a mounting edge, and the mounting edge is provided with mounting holes at intervals. The main body of the car door cover is integrally formed. The mounting holes are passed through the screw posts. The left side of the main body of the car door cover extends to the upper side of the boss and is open at the top. Together with the boss, it divides the lower bottom plate into a front storage cavity and a rear storage cavity. The right side of the main body of the car door cover is sealed to the upper side of the recess. The lower side of the main body of the car door cover extends beyond the main body of the inner door panel and bends backward to form a lower arc edge. Speaker cover: The speaker cover is installed on the outer cover of the door and corresponds to the inner recess.

[0006] According to one embodiment of the present invention, the space of the front cavity is smaller than the space of the rear cavity.

[0007] According to one embodiment of the present invention, an inspection port cover is also provided on the lower side of the main body of the outer door cover.

[0008] According to one embodiment of the present invention, the upper side of the inner panel of the car door is concave relative to the front storage cavity and the rear storage cavity.

Detailed Implementation

[0015] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0016] Please refer to Figures 1 to 2 , Figure 1 This is a schematic diagram of the conveniently assembled door inner cover trim panel integrated assembly according to an embodiment of this utility model; Figure 2 This is an exploded view of the conveniently assembled door inner cover trim panel integrated assembly according to an embodiment of this utility model.

[0017] As shown in the figure, a conveniently assembled door inner cover trim panel integrated assembly includes a door inner panel body 10, a door outer cover body 30, and a speaker cover 50. The three components achieve functional integration through modular design, and the assembly steps are simplified. The specific structure is as follows: The main body 10 of the door inner panel is made using a one-piece molding process (such as injection molding) to ensure structural integrity and strength. Its lower left side has an outwardly folded bottom plate 11, which is used to form the bottom support of the storage space; the right side is set with an inward recess 12, which serves as a speaker mounting area to prevent the speaker from protruding from the surface of the trim panel, thereby improving aesthetics and space compactness.

[0018] In one embodiment, the lower bottom plate 11 has an upwardly extending boss 13, which not only serves to separate the storage space, but also enhances the structural strength of the lower bottom plate 11 and prevents deformation caused by placing heavy objects; the edge of the inner door panel body 10 is surrounded by a mounting edge 20, and the mounting edge 20 is provided with mounting holes 21 spaced apart for fixing with the body and the outer door cover body 30, and the spaced mounting holes 21 can ensure that the fixing points are evenly distributed, thereby improving the structural stability after assembly.

[0019] The main body 30 of the car door outer cover is also made of one-piece molding process. The mounting holes 21 of the main body 10 of the car door inner panel are inserted through the screw posts to achieve quick fixation with the main body 10 of the car door inner panel. Assembly can be completed by simply tightening the screws, without the need for additional positioning process.

[0020] Furthermore, the left side of the door cover body 30 extends to the upper side of the protrusion 13, and its upper end is open. Through the cooperation between the protrusion 13 and the door cover body 30, the lower bottom plate 11 is divided into a front storage cavity 31 and a rear storage cavity 32, realizing the classified storage of items. Preferably, the space of the front storage cavity 31 is smaller than that of the rear storage cavity 32, which conforms to the user's daily usage habits—small items are needed frequently but occupy little space, while large items are needed infrequently but occupy a lot of space. This design can achieve efficient use of storage space; for example, the front storage cavity 31 can hold small items such as mobile phones and keys, while the rear storage cavity 32 can hold larger items such as water cups and tissue boxes.

[0021] The right side of the door outer cover body 30 is sealed to the upper side of the recess 12, forming a closed installation space for the speaker, preventing dust and impurities from entering the speaker, while ensuring the normal transmission of speaker sound. The lower side of the door outer cover body 30 extends beyond the door inner panel body 10 and bends backward to form a lower arc edge 40. This edge not only covers the connection gap between the door inner panel body 10 and the door body, enhancing the decorative effect, but also strengthens the impact resistance of the lower edge of the door outer cover body 30, preventing collision deformation.

[0022] The main body 30 of the car door cover of this utility model is also provided with an inspection port cover 60 on the lower side. The inspection port cover 60 is connected to the main body 30 of the car door cover by a buckle. When it is necessary to inspect the speaker or the internal wiring of the car door, only the inspection port cover 60 needs to be removed, without removing the entire inner cover panel, which greatly improves the convenience of inspection.

[0023] The speaker cover 50 is installed in the corresponding recess 12 of the door cover body 30 and is fixed by a snap or screw (snap is preferred for easy disassembly and maintenance). The surface of the cover has sound holes to ensure that the speaker sound is transmitted normally, and at the same time, it serves as a dustproof and protective measure to prevent foreign objects from contacting the speaker diaphragm.

[0024] In a preferred embodiment, the upper side of the inner door panel 10 relative to the front storage cavity 31 and the rear storage cavity 32 is concave by an arc. This arc design is ergonomically adapted, which can reduce the feeling of pressure and improve the riding comfort when the passenger's arm rests on the trim panel. At the same time, the concave structure can enhance the bending strength of the inner door panel 10 and prevent deformation after long-term use.

[0025] In addition, multiple mounting posts and reinforcing ribs are provided on the back of the lower curved edge 40 and the back of the inner door panel body 10. The mounting posts are used for fixed connection with the door body to ensure that the entire integrated component is firmly installed on the door. The reinforcing ribs are arranged in a cross or parallel manner, which can significantly improve the structural strength of the lower curved edge 40 and the inner door panel body 10 without increasing the thickness of the components, and prevent vibration noise or collision damage.

[0026] In summary, this utility model has a high degree of integration, is easy to assemble, has a reasonable storage layout, and is convenient to maintain. It is applicable to various passenger cars and commercial vehicles, and combines practicality and economy.

[0027] 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.
