Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a car door corner protection structure. Background Technology

[0002] A car door consists of an outer panel, an inner panel, a door frame, a glass guide channel, hinges, a lock, and other accessories. To enhance safety, a crash bar is typically installed on the inside of the outer panel. The inner and outer panels are joined together using methods such as flanging, bonding, and welding. Depending on the load-bearing capacity, the outer panel needs to be lightweight while the inner panel must be rigid enough to withstand significant impacts.

[0003] Door exterior panels are plastic components installed along the edges of car doors, commonly referred to as door trim panels. These panels not only serve a decorative function but also conceal the complex internal structure of the door, reducing scratches and impact damage when the door is opened and closed. Furthermore, they provide sound insulation, effectively blocking external noise and ensuring a quiet cabin, further enhancing passenger comfort. Door exterior panels are typically made of hard plastic, soft rubber, or leather. Common examples include door pillar trim panels and side skirts.

[0004] The problem with existing technology is that when a car door is opened or closed, the bottom corner of the door is prone to scraping and bumping, and the existing exterior trim panel lacks protection for this area; when the door is closed, there is no buffer between the outer edge of the door and the vehicle body, which can easily cause impact, damage, and affect the service life of the parts. Summary of the Invention

[0005] The purpose of this utility model is to address the problems existing in the prior art by providing a car door corner protection structure, which has the advantages of convenient installation, good protection effect and simple structure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a car door corner protection structure, including a front panel body and a rear panel body arranged in parallel. The rear panel body includes an adhesive part and a groove part. A connecting part is provided between the front panel body and the groove part. A triangular connecting groove for cooperating with the corner of the car door is formed between the front panel body and the groove part. An adhesive layer for connecting with the inner side of the car door is provided on the connecting part. A reinforcing plate layer is bonded to the front side of the front panel body. An elastic buffer pad is provided on the rear side of the rear panel body along the vertical direction.

[0007] In the above solution, a triangular connecting groove is formed by the cooperation of the front panel body and the rear panel body. The triangular connecting groove is used to engage with the lower corner of the car door. A reinforcing plate layer is glued to the front side of the front panel body to protect the door corner and prevent direct scratches or bumps to the bottom of the door when opening the door. An adhesive layer is provided on the connecting part to facilitate bonding and fixing with the car door and prevent it from falling off. An elastic buffer pad is used to buffer when the car door is closed to avoid direct collision between the car door and the car body.

[0008] Furthermore, the elastic buffer pad includes a corrugated tube body, which is perpendicular to the rear plate body. The rear end of the corrugated tube body is connected to a flat end face, and the outer ring of the flat end face is provided with a forward-facing annular flared portion.

[0009] By incorporating a corrugated tube body, the door and vehicle body are cushioned when the door is closed, reducing impact. The flat end face is used to contact the vehicle body, and the annular flared part is located on the outer ring of the corrugated tube body. When the door is closed, the annular flared part contacts the rear panel body to enhance the cushioning effect.

[0010] Furthermore, a flexible sponge is provided on the rear side of the rear plate body, and the flexible sponge is located in the middle of the corrugated pipe body.

[0011] Flexible sponge is placed inside the corrugated pipe to enhance the cushioning effect and protect the car door.

[0013] The structure is designed with right-angled triangles to correspond to the shape of the car door. The reinforcing plates have high hardness and can withstand impacts. The front and rear main bodies are made of non-metallic flexible materials with low hardness, which can buffer impacts and protect the car door from scratches.

[0014] Furthermore, the connecting portion includes two perpendicularly intersecting side connecting strips, and the connecting portion is located between the edge of the front plate body and the edge of the groove portion.

[0015] The two side connecting strips are simple in structure. The connectors are connected to the edge of the front panel body and the edge of the groove to ensure the positioning between the front panel body and the rear panel body and to achieve engagement with the corner of the door.

[0016] Furthermore, an adhesive layer two is provided on the inner side of the inclined side of the front panel body, and the connecting part is connected to the two right-angled sides of the front panel body. The lengths of the two side connecting strips are respectively less than the lengths of the corresponding right-angled sides of the front panel body.

[0017] A second adhesive layer is provided to ensure a stable fit between the front panel body and the door. The lengths of the two side connecting strips are shorter than the lengths of the right-angled sides of the front panel body to facilitate bending of the front panel body, setting up the second adhesive layer, and performing the bonding operation.

[0018] Furthermore, a first plastic film is detachably provided at one location of the adhesive layer, and a second plastic film is detachably provided at another location of the adhesive layer. When not in use, the first and second plastic films protect the adhesive layers; they are removed when needed.
