[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] See also Figure 1 and Figure 2 Now, a bumper provided by the utility model is described. A bumper includes a bumper body 100, a vehicle film decorative layer 200 and a light source assembly 300.

[0026] The bumper body 100 is made of a light-transmitting material; the vehicle film decorative layer 200 is arranged on the outer side of the bumper body 100, and the vehicle film decorative layer 200 includes at least a color paint layer 240 and a light-transmitting repair layer 250, the color paint layer 240 forms a light-transmitting pattern area for decorating the bumper body 100, and the light-transmitting repair layer 250 is located on the outer side of the color paint layer 240, and the light-transmitting repair layer 250 is softened by heating to repair its own scratches or dents; the light source assembly 300 is arranged on the inner side of the bumper body 100, and the light source assembly 300 provides light that sequentially penetrates the bumper body 100, the light-transmitting pattern area and the light-transmitting repair layer 250.

[0027] The utility model provides a bumper. Compared with the prior art, the bumper body 100 is made of a light-transmitting material, the car film decorative layer 200 is located on the outside of the bumper body 100, and the light source assembly 300 is located on the inside of the bumper body 100. The car film decorative layer 200 has a paint layer 240 and a light-transmitting repair layer 250. The paint layer 240 can form a light-transmitting pattern area. The light emitted by the light source assembly 300 sequentially penetrates the bumper body 100, the light-transmitting pattern area of ​​the paint layer 240, and the light-transmitting repair layer 250, thereby forming the desired color and pattern on the outermost side of the bumper. The utility model provides a bumper. When the bumper is bumped or scratched, the outer light-transmitting repair layer 250 will form scratches or dents. The light-transmitting repair layer 250 is heated to soften it, thereby achieving the effect of repairing its own scratches or dents, without the need for re-spraying, and the later maintenance is convenient and the maintenance cost is low.

[0028] Compared with the prior art method of using spraying, baking, laser engraving, spraying, baking to form a light-transmitting coating on the bumper, the bumper provided by the utility model is

[0029] The bumper body 100 is made of PC or transparent PP material. The wall thickness of the bumper body 100 is 3-6mm. The PC material is polycarbonate, commonly known as engineering plastics. The PC material is an amorphous polymer in an almost colorless glass state with good optical properties. The transparent PP material is polypropylene, which has high impact resistance, strong mechanical properties, and resistance to corrosion by various organic solvents and acids and alkalis. The bumper body 100 made of PC material or transparent PP material can ensure that it has high light transmittance and impact resistance. PC can be made into high light transmittance and semi-light transmittance effects, and PP can be made into semi-light transmittance effects.

[0030] In addition, the light source assembly 300 includes multiple LED light sources and / or projection equipment. When the light source assembly 300 adopts multiple LED light sources, the multiple LED light sources are installed on the inner side of the bumper. The multiple LED light sources are LED light sources of different colors. The length and width of the light source are adjusted according to the size of the bumper and the light-transmitting pattern; by adjusting the light sources of different colors, different color texture effects are displayed. The projection equipment is arranged on the inner side of the bumper body 100. When the light source assembly 300 adopts a projection equipment, the projection equipment is used in conjunction with a PC fully transparent bumper for projection. In addition, the light source assembly 300 can also adopt a combination of multiple LED light sources and projection equipment to achieve better light-transmitting imaging effects.

[0031] The vehicle film decorative layer 200 also includes an adhesive layer 210, a bearing layer 220, a heating shading layer 230, a light-transmitting repair layer 250 and a protective layer 260, which are arranged in sequence from the inside to the outside. The color paint layer 240 is located between the heating shading layer 230 and the light-transmitting repair layer 250. The vehicle film decorative layer 200 is composed of the above six layers, which are integrated together through the process to form the vehicle film decorative layer 200. The color paint layer 240 is formed by blending pigments and TPU through a blending process to achieve a decorative effect. The thickness is about 10 to 30 μm. The thickness of the color paint layer 240 is relatively thin, and the shape of its own light-transmitting pattern area can be revealed through light. The color paint layer 240 is located on the inner side of the light-transmitting repair layer 250. When the bumper collides or scratches, the light-transmitting repair layer 250 is deformed first, which can protect the light-transmitting pattern area of ​​the color paint layer 240. The heating shading layer 230 is located on the inner side of the color paint layer 240. The heating shading layer 230 can provide a corresponding shading area on the inner side, and at the same time facilitate the electrical connection and heating between the heating shading layer 230 and the vehicle power supply.

[0032] Specifically, the adhesive layer 210 is a transparent heat-sensitive adhesive or a transparent pressure-sensitive adhesive. The adhesive layer 210 is used to bond the bearing layer 220 to the outer side of the bumper body 100. The thickness is about 10 to 50 μm. The thickness of the adhesive layer 210 itself is selected according to the firmness of the bonding, and is not specifically limited here. The heat-sensitive adhesive uses aluminum foil composite cloth as the base material, and has good initial adhesion, excellent cohesion, and good weather resistance. The pressure-sensitive adhesive is mainly a solvent-based or latex-based adhesive of acrylic and rubber series.

[0033] The bearing layer 220 is made of TPU material, which is a thermoplastic polyurethane elastomer rubber with good tensile properties. It plays the role of bearing adhesive, coating and protection, and has a thickness of about 30 to 150 μm. The bearing layer 220 is bonded to the adhesive layer 210, and the heating and light-shielding layer 230 is arranged on the outside of the bearing layer 220. The bearing layer 220 is the main stress-bearing layer, and the adhesive layer 210 is arranged on the inside, and the two main functional layers of the heating and light-shielding layer 230 and the light-transmitting repair layer 250 are arranged on the outside in sequence. Therefore, when designing its thickness, the bonding strength on the inside and the bearing strength on the outside should be fully considered.

[0034] The heating shading layer 230 includes a conductive coating formed by at least one of black graphene, carbon nanotubes and conductive carbon black that is connected to a power source and generates heat. It plays a shading and heating role, blocking light penetration. The heating shading layer 230 is formed with a certain texture pattern through printing or laser engraving equipment (a light-transmitting texture effect is formed by removing the heating shading layer 230). After the vehicle power supply is turned on, it can generate heat to heat the bumper and the car film. The thickness is about 5 to 50 μm. The thickness of the heating shading layer 230 varies depending on the selection of the above-mentioned black graphene, carbon nanotubes and conductive carbon black materials.

[0035] The light-transmitting repair layer 250 is made of resin material. The resin softens when the temperature rises. The heating temperature is generally 60°C to 70°C. Part of the outer surface of the resin material softens, and scratches, dents, etc. can be repaired through its own fluidity or external pressure. The thickness is about 20 to 60 μm. The protective layer 260 on the outside of the light-transmitting repair layer 250 can buffer part of the impact, but the light-transmitting repair layer 250 should also have a certain thickness, generally not less than 20 μm. At the same time, the light-transmitting repair layer 250 cannot be too thick to avoid affecting its light transmittance.

[0036] The protective layer 260 is made of TPU or PET. TPU is a thermoplastic polyurethane elastomer rubber with good tensile properties, and plays the role of carrying adhesives, coatings and protection. PET is a polyethylene terephthalate plastic. PET has good optical properties and weather resistance. Amorphous PET plastic has good optical transparency. The protective layer 260 covers the outside of the light-transmitting repair layer 250, and has a smooth outer surface. It plays the role of carrying coatings, protection and decoration. The thickness is about 30 to 150 μm. The thickness of the protective layer 260 can be adjusted according to the specific vehicle model. In order to achieve the protective effect, its thickness cannot be less than 30 μm; for off-road vehicles, the thickness can be appropriately increased, but generally not more than 150 μm, so as not to affect its aesthetics and light transmittance.

[0037] This solution combines colors and textures by bonding the car film decorative layer 200, and sticks it on the bumper surface through equipment. It has low requirements for production lines, high production efficiency, and can also achieve free selection of patterns for manual sticking. The subsequent maintenance cost is low and convenient. In case of minor scratches, the relative coating process can achieve self-repairing effect by heating the light-transmitting repair layer 250 itself; in snowy weather, the surface ice and snow can be removed by heating the heated shading layer 230 to improve vehicle safety; at the same time, our car film decorative layer 200 has three main layers of film, namely the heated shading layer 230, the color paint layer 240 and the light-transmitting repair layer 250, which can completely simulate the light-transmitting coating solution and have better decorative and protective effects than the commercially available two-layer car cover / film.

[0038] Based on the same inventive concept, the utility model also provides a vehicle, which uses the above-mentioned bumper, thereby giving the vehicle's bumper a light-transmitting and personalized pattern effect, improving the production and processing efficiency of the bumper, practicing the concept of low-carbon environmental protection, and at the same time facilitating the owner's later maintenance and replacement, thereby reducing maintenance costs.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
