Description

Technical Field

[0001] This utility model belongs to the field of automotive plastic parts technology, specifically relating to an automotive door panel structure. Background Technology

[0002] In the design of plastic exterior parts, such as door panels with rubber strip snap-fit ​​structures, because the textured PP resin plastic product is assembled with a small bracket into a small assembly before being installed on the front side door of the car, it is necessary to comprehensively consider the molding of the product structure, whether there are any undercuts in the product structure, whether there is enough space in the product assembly structure for the removal of sliders or angled tops, whether it will scratch the painted surface of the front side door, and whether it can meet the appearance requirements of the product. The existing automotive door panel structure is not only inefficient to assemble, but also wobbles when the product angle changes, is troublesome to install, and causes scratches and abnormal noises from the body sheet metal under gravity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a car door panel structure that is simple in structure, easy to assemble, and avoids scratches and abnormal noises on the car body sheet metal under the action of gravity, in light of the current state of the technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a car door guard plate structure, characterized in that it includes a main body, the main body has multiple bases, connecting buckles are installed on the bases, the bases have guide grooves, double rows of symmetrical convex truncated cones are provided on the seat surface of the bases, and an integrally formed rubber strip mounting groove is provided at the lower part of the bases.

[0005] The main component of this patent is an injection-molded part. The various structures on this injection-molded part are used for assembly with the front side door of a car, serving a decorative purpose. All sub-parts are integrally injection-molded resin products. The guide groove primarily guides the assembly of the connecting clips. Additionally, the double-row symmetrical convex platforms mainly serve to pre-position the clips and absorb the deformation of the polymer material during thermal expansion and contraction during online assembly and vehicle road testing. During online installation, the small protrusions control the clip position, preventing wobbling due to changes in the product's angle, facilitating alignment with the sheet metal mounting holes. Furthermore, the adhesive strip mounting groove provides positioning guidance for the EPDM installation, ensuring foolproof installation.

[0006] In the aforementioned automotive door panel structure, the lower part of the main component has a flange, and a short rubber strip is provided on the flange. Here, the rubber strip, along with the EPDM rubber strip in the mounting slot and the short rubber strip on the flange, forms a stable triangular structure. This prevents the product from being scratched or causing abnormal noises on the vehicle body sheet metal under gravity, thus protecting the door and the entire product assembly.

[0007] In the aforementioned automotive door panel structure, the base has folded edges on its sides. The downward slope of these folded edges serves to prevent the product from rotating.

[0008] In the aforementioned automotive door panel structure, the base surface has a double-ribbed contact area. This ensures the assembly and matching of the connecting clips while also facilitating mold repair and adjustment.

[0009] In the aforementioned automotive door panel structure, a sloping pull-out portion is formed on the main body. This sloping pull-out portion increases the effective adhesion area of ​​the adhesive tape, ensuring effective assembly. The overall main body has reduced adhesive content, ensuring smooth transitions between variations in wall thickness and thus preventing turbulence on the surface.

[0010] Compared with the prior art, the advantages of this utility model are that the various structures of the car door guard plate ensure the reliability of the installation and the effectiveness of the assembly, and will not shake due to changes in the angle of the product. In addition, it avoids the product from scratching and making abnormal noises on the car body sheet metal under the action of gravity, thus playing a role in protecting the car door and the product assembly. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of a car door panel;

[0012] Figure 2 This is a schematic diagram of the structure of the car door panel from another direction. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] In the figure, the main body is 100; the base is 200; the guide groove is 300; the symmetrical convex frustum is 400; the rubber strip mounting slot is 500; the flange is 600; the short rubber strip is 700; the folded edge is 800; the double rib contact part is 900; and the inclined top pull part is 1000.

[0015] like Figure 1 and Figure 2As shown, this automotive door panel structure includes a main body 100, with multiple bases 200 on the main body 100. Connecting buckles are installed on the bases 200, and guide grooves 300 are provided on the bases 200. Double-row symmetrical convex truncated cones 400 are provided on the seat surface of the bases 200. An integrally formed rubber strip mounting groove 500 is provided at the lower part of the bases 200. The main body 100 of this patent is an injection molded part. The various structures on this injection molded part are used to assemble with the front side door of the car, serving a decorative function. The sub-parts of the component are all integrally injection molded resin products. The guide grooves 300 mainly serve to guide the connecting buckles during assembly. In addition, the double-row symmetrical convex truncated cones 400 mainly serve to pre-position the buckles and absorb the deformation of the polymer material during thermal expansion and contraction during online assembly and vehicle road testing. When the clips are installed online, the small protrusion can control the position of the clips and prevent them from shaking due to changes in the product's angle, making it easy to align with the sheet metal mounting holes. In addition, the 500 rubber strip mounting slot can provide positioning guidance for the installation of EPDM, ensuring foolproof product installation.

[0016] As a further optimization, the lower part of the main body 100 has a flange 600, on which there is a short rubber strip 700. Here, the rubber strip is installed with a 500 EPDM rubber strip and combined with the short rubber strip 700 on the flange 600 to form a stable triangular structure, which avoids scratches and abnormal noises on the body sheet metal under the action of gravity, and plays a role in protecting the door and product assembly. The side of the base 200 has a folded edge surface 800. Here, the downward sinking of the two folded edge surfaces 800 plays a role in preventing the product from rotating. The seat surface of the base 200 has a double rib line contact part 900, which ensures the assembly matching of the connecting buckle and also facilitates mold repair and adjustment. The main body 100 has a sloping top pull part 1000, which increases the effective adhesion area of ​​the tape and ensures the effectiveness of the assembly. The overall main body 100 is reduced in rubber, which ensures the smooth connection of the overall wall thickness variation, thereby avoiding the occurrence of surface turbulence.

[0017] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications to the described specific embodiments or adopt similar methods to replace them, but without departing from the scope defined by the spirit of this utility model.
