A flexible sheet metal vehicle body protection structure based on adhesive bonding and serrated edge binding

Abstract

This utility model discloses a plastic sheet vehicle body protection structure based on adhesive bonding and serrated edge wrapping, including a wrapping layer, an adhesive layer, and an edge structure. The wrapping layer is made of one or more plastic sheets such as PVC, PC, ABS, PMMA, and PP, and is manufactured through processes such as bending and shaping, vacuum forming, and 3D printing. Its shape matches the vehicle's exterior parts and tightly wraps at least one painted surface and all sides. The adhesive layer is an adhesive layer that is applied to the area around the vehicle. After curing, it is transparent and colorless and is used to seal and bond the wrapping layer to the vehicle's exterior parts. The edge structure is a continuous serrated structure processed on the side wrapping part of the wrapping layer. It is embedded in the adhesive layer to form a mechanical interlock. The depth, density, and shape of the serrations can be adjusted as needed. The forming method is one or more of CNC machining, laser cutting, vacuum forming, or mold hot pressing.

Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a plastic sheet material vehicle body protection structure based on adhesive bonding and serrated edge binding. Background Technology

[0002] Traditional vehicle body protection structures often use single-material films or sheets, simply glued together. However, these structures have poor impact resistance, are easily damaged by external forces, and cannot effectively protect the vehicle surface. Their edge strength is insufficient, leading to warping and detachment after a period of use, affecting the protective effect and the vehicle's appearance. Furthermore, their design is limited, failing to meet individual user needs, and their production and construction processes are complex, requiring extensive on-site cutting and shaping, increasing construction difficulty and cost, and hindering large-scale promotion. Therefore, a new type of vehicle body protection structure based on adhesive bonding and serrated edges has been introduced. Utility Model Content

[0003] The purpose of this invention is to provide a plastic sheet material vehicle body protection structure based on adhesive bonding and serrated edge binding, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic sheet material vehicle body protection structure based on adhesive bonding and serrated edge wrapping, comprising an adhesive layer formed by applying adhesive to the paint surface of the vehicle body, a wrapping layer adapted to a part of the vehicle body is bonded and installed on the adhesive layer, the edge of the wrapping layer is provided with a serrated edge structure, and the edge structure is spliced ​​with the adhesive layer to improve the fixing strength.

[0005] Preferably, the wrapping layer is a plastic sheet made of one or more materials selected from PVC, PC, ABS, PMMA, and PP, with a thickness of 0.15mm to 3.0mm.

[0006] Preferably, the edge structure is integrally formed with the wrapping layer, the length of the edge structure is the same as the side length of the wrapping layer, and the width is multiple times the thickness of the wrapping layer.

[0007] Preferably, the edge structure is formed by any one of CNC machining, laser cutting, or hot pressing.

[0008] Compared with existing technologies, the beneficial effects of this utility model are as follows: This invention improves impact resistance and edge strength by using a plastic sheet material to create a wrapping layer and combining it with a special edge structure and adhesive layer; it enables personalized appearance design, prefabrication of components in factories, and simple installation in stores, shortening construction time by more than 50% and reducing costs and construction barriers; the weight of the protective structure is reduced by more than 60% compared with traditional metal components, it is non-destructive to install, recyclable, and resistant to aging, maintaining stable performance in a temperature range of -40℃ to 80℃, and is compatible with the vehicle's original protection system. It does not chemically react with the vehicle body during use, is partially replaceable, easy to maintain, and can extend its service life. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1-3 This utility model provides a technical solution: a plastic sheet material vehicle body protection structure based on adhesive bonding and serrated edge wrapping, including a wrapping layer 2, an adhesive layer 1 and an edge structure 3, which is suitable for the protection of shell components of various vehicles.

[0015] During production, the wrapping layer 2 is made of one or more malleable sheets selected from PVC, PC, ABS, PMMA, and PP. It is processed according to the shape of the vehicle's exterior components through bending, shaping, vacuum forming, and compression molding, with a thickness controlled between 0.15mm and 3.0mm to ensure tight coverage of at least one painted surface and all sides. The edge structure 2 is formed by processing the wrapped portion of the wrapping layer 2 into a serrated edge structure. This serrated structure improves the connection strength with the adhesive layer 1. The edge structure 2 is formed using CNC machining, laser cutting, or hot pressing. The adhesive layer 1 uses a suitable adhesive material, applied to the area surrounding the vehicle, sealing and bonding the wrapping layer 2 to the vehicle's exterior components. After curing, the adhesive layer 1 is transparent and colorless.

[0016] When in use, the factory prefabricates each component in a modular fashion and transports them to the store. The store can complete the installation with simple tools without modifying the vehicle's exterior parts. After installation, patterns can be printed or colors can be applied to the surface of the wrapping layer 2 as needed. Regular maintenance can extend its service life. When it reaches the end of its service life or is partially damaged, the wrapping layer 2 can be replaced without damaging the vehicle's surface.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
