Description

Technical Field

[0001] This utility model belongs to the field of automotive plastic parts technology, specifically relating to an anti-scratch trim for automotive doors. Background Technology

[0002] In the design of plastic exterior parts, such as the leather-textured front door anti-scratch part with electroplated bright strips, because the electroplated bright strips are attached to the leather-textured PP resin body of the ABS plastic part before being assembled onto 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. Because the product is installed on the front side door of the car, the existing products have shrinkage after installation, forming lines on the surface, and the ends are warped, while also producing noise and abnormal sounds. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a car door anti-scratch trim that is simple in structure, easy to install, and effectively prevents shrinkage and end warping, 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 anti-scratch trim, characterized in that it includes a body, the body having a connecting claw and a buckle mounting platform, a diagonal rib portion on the right end of the body, the diagonal rib portions being staggered, and a platform overlapping rib portion to prevent end warping provided on the left end of the body.

[0005] In the aforementioned car door anti-scratch trim, the lower side of the main body has a double-sided adhesive tape area, and there are a total of 5 double-sided adhesive tape areas.

[0006] In the aforementioned car door anti-scratch trim, the upper right edge of the main body has a frustum portion.

[0007] In the aforementioned car door anti-scratch trim, the body has a flange around its perimeter, and protrusions are arranged on the flange.

[0008] In the aforementioned car door anti-scratch trim, the back of the main body is provided with back ribs.

[0009] Compared with the prior art, the advantages of this utility model are that the end warping problem of the anti-scratch strip can be solved through various structures, the entire car door anti-scratch trim is installed stably and reliably with good strength, and the noise problem between the electroplated strip and the leather-textured PP parts is also solved. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of the anti-scratch trim on the car door;

[0011] Figure 2 This is a schematic diagram of the back structure of the anti-scratch trim on the car door. Detailed Implementation

[0012] 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.

[0013] In the diagram, the main body is 100; the connecting claw is 200; the buckle mounting platform is 300; the diagonal rib is 400; the platform overlapping rib is 500; the double-sided tape part is 600; the truncated cone is 700; the flange is 800; the boss is 900; and the back rib is 1000.

[0014] like Figure 1 and Figure 2 As shown, this automotive door anti-scratch trim includes a body 100. This patented automotive door anti-scratch trim is a one-piece injection-molded resin product. It is assembled with the front side door of a car using this structure, serving a decorative function. The body 100 has connecting claws 200 and buckle mounting platforms 300, which serve a connecting and mounting function. On the right end of the body 100, there are diagonal ribs 400, which are staggered. On the left end of the body 100, there are platform overlapping ribs 500 to prevent end warping. The diagonal ribs 400 are staggered to prevent the PP material from shrinking and forming lines on the surface under similar conditions. The large angle serves as a guide. In addition, the platform overlapping ribs 500 are mainly used when there is insufficient space at the top of the slope. In areas where there is space at the top of the slope, the slope is used, which effectively ensures a significant increase in the adhesion area of ​​the double-sided tape and prevents the end warping problem of previous anti-scratch strips.

[0015] As a further optimization, the lower side of the main body 100 has five double-sided adhesive tape portions 600. These portions prevent warping due to product vibration and abnormal noises when pressed, ensuring assembly force for parts where installation structures cannot be arranged, while also acting as a buffer. A frustum 700 is located on the upper right edge of the main body 100. This frustum 700 increases the strength of the upper frame of the product and effectively prevents scratches during online assembly. Additionally, the main body 100 of this patent has a folding mechanism around its perimeter. Edge 800 has protrusions 900 arranged on it. The protrusions 900 structure on the entire circumference of the flange 800 are used here, which effectively absorbs the tolerance of the serpentine deformation of similar long strip products in the past, and prevents noise and abnormal sounds between the electroplated strip and the leather-textured PP parts. In order to ensure the installation strength, the back of the body 100 is provided with back ribs 1000. The back ribs 1000 improve the strength of the claws on the electroplated bright strip product on the one hand, and improve the size of the opening of the PP leather-textured body 100 on the other hand, ensuring the strength of the mold protrusion.

[0016] 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.
