[0025] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0026] Reference will be made below to Figures 1-3 describe the bumper 100 according to an embodiment of the first aspect of the present utility model.
[0027] As Figure 1 and Figure 3 shown, the bumper 100 according to the embodiment of the first aspect of the present utility model includes: a bumper body 10 and a covering film 20.
[0028] Specifically, the covering film 20 is formed by thermoforming on the outer surface of the bumper body 10 and covers the outer surface of the bumper body 10.
[0029] During the production process, the color of the covering film 20 is matched according to the color of the vehicle body, and then the covering film 20 is thermoformed on the outer surface of the bumper 100, and the covering film 20 covers the outer surface of the bumper body 10. Thus, the production of the bumper 100 that matches the vehicle body color can be realized.
[0030] It can be understood by those skilled in the art that thermoforming requires less time and the thermoforming process is simple. Thus, the production efficiency of the bumper 100 can be improved and the production cost of the bumper 100 can be reduced. In addition, after thermoforming, the covering film 20 fits well with the outer surface of the bumper body 10, which can improve the yield rate of the bumper 100.
[0031] For the bumper 100 according to the embodiment of the first aspect of the present utility model, by thermoforming the covering film 20 on the outer surface of the bumper body 10, the coloring of the bumper 100 can be realized and there is no need to spray paint on the outer surface of the bumper 100, thereby improving the production efficiency of the bumper 100 and reducing the production cost of the bumper 100.
[0032] In some embodiments of the present utility model, as Figures 1-3 shown, a plurality of exhaust holes 11 penetrating through the bumper body 10 in the thickness direction are formed on the bumper body 10.
[0033] During the thermoforming process, the vacuum pump will extract the air on the side of the bumper body 10 away from the covering film 20. Under the action of the air pressure difference, the covering film 20 is adsorbed on the bumper body 10. By providing a plurality of exhaust holes 11, the vacuum pump can extract the air between the covering film 20 and the bumper body 10 from the exhaust holes 11, so as to ensure that the fitting effect of the covering film 20 on the bumper body 10 meets the use requirements.
[0034] At the same time, the exhaust holes 11 can reduce the weight of the bumper 100, which is beneficial to the realization of the lightweight design of the vehicle.
[0035] In some embodiments of the present utility model, in the direction of the covering film 20 towards the bumper body 10, the cross-sectional dimension of the exhaust hole 11 gradually increases. That is to say, the cross-sectional dimension of the end of the exhaust hole 11 close to the covering film 20 is smaller, and the cross-sectional dimension of the end of the exhaust hole 11 close to the vacuum pump is larger. In this way, the efficiency of air discharge from between the covering film 20 and the bumper 100 can be improved, the production efficiency can be increased, and the probability of the covering film 20 being sucked into the exhaust hole 11 can be reduced, thereby improving the yield rate during the production process.
[0036] In some embodiments of the present utility model, the exhaust hole 11 is a round hole, and the inner diameter of the exhaust hole 11 is 1 mm - 1.2 mm. For example, the inner diameter of the exhaust hole 11 can be 1 mm, 1.05 mm, 1.1 mm, 1.18 mm or 1.2 mm. Thus, the efficiency of air discharge from between the covering film 20 and the bumper 100 and the probability of the covering film 20 being sucked into the exhaust hole 11 can meet the production requirements. During the product design process, the inner diameter of the exhaust hole 11 can be adjusted to meet more product design requirements. Among them, the exhaust hole 11 is a round hole, and the stress distribution along the circumference of the exhaust hole 11 is relatively concentrated, which can further improve the yield rate.
[0037] In some embodiments of the present utility model, on the outer surface of the bumper body 10, the ratio of the total area of the plurality of exhaust holes 11 to the surface area of the bumper body 10 is 0.4 - 0.45. For example, the ratio of the total area of the plurality of exhaust holes 11 to the surface area of the bumper body 10 can be 0.4, 0.405, 0.41, 0.42, 0.422, 0.43, 0.44 or 0.45. Thus, the adsorption strength of the covering film 20 on the bumper body 10 and the structural strength of the bumper body 10 can meet the usage requirements. During the product design process, the ratio of the total area of the plurality of exhaust holes 11 to the surface area of the bumper body 10 can be adjusted to meet more product design requirements.
[0038] In some embodiments of the present utility model, the covering film 20 is adhesively connected to the bumper body 10. It can be understood that during the driving process of the vehicle, the impact force of the air on the bumper 100 is relatively large. The covering film 20 is heat-formed on the outer surface of the bumper body 10, and at the same time, the covering film 20 is adhesively connected to the bumper body 10, which can improve the connection reliability of the covering film 20 on the outer surface of the bumper body 10.
[0039] In some embodiments of the present utility model, the covering film 20 is one of a PVC (Polyvinyl Chloride) film, a PP (Polypropylene) film, a PET (Polyethylene Terephthalate) film, or a PS (Polystyrene) film. Thus, the chemical and physical properties of the covering film 20 can meet the usage requirements. During the product design process, the material of the covering film 20 can be adjusted to meet more product design requirements.
[0040] In some embodiments of the present utility model, the thickness of the covering film 20 is 0.8 mm - 1.2 mm. For example, the thickness of the covering film 20 can be 0.8 mm, 0.84 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.15 mm, or 1.2 mm. Thus, the strength of the covering film 20 can meet the usage requirements. During the product design process, the thickness of the covering film 20 can be adjusted to meet more product design requirements.
[0041] In some embodiments of the present utility model, the bumper body 10 is an ABS (Acrylonitrile-Butadiene-Styrene) part or a PP (Polypropylene) part. Thus, the chemical and physical properties of the bumper body 10 can meet the usage requirements. During the product design process, the material of the bumper body 10 can be adjusted to meet more product design requirements.
[0042] In some embodiments of the present utility model, the bumper body 10 is injection molded. Injection molding has a relatively high production efficiency and a high product consistency. By injection molding the bumper body 10, the production efficiency of the bumper 100 can be further improved, and the yield rate of the bumper 100 can be increased.
[0043] In some embodiments of the present utility model, as Figure 3 shown, a plurality of mounting protrusions 12 protruding away from the covering film 20 are formed at the edge of the bumper body 10. The mounting protrusions 12 are used for connecting with the vehicle body. By providing a plurality of mounting protrusions 12, each mounting protrusion 12 can position and limit the bumper 100. In this way, the mounting accuracy of the bumper 100 on the vehicle body can be improved, thereby reducing the surface difference between the bumper 100 and the surrounding components, and improving the connection reliability between the bumper 100 and the vehicle body. Among them, preferably, the mounting protrusions 12 are snap-connected to the vehicle body.
[0044] The following describes the production process of the bumper 100 according to the embodiments of the present utility model.
[0045] First, preheat the bumper body 10 and heat the covering film 20. Then, spray an adhesive on the outer surface of the bumper body 10. Subsequently, place the heated covering film 20 on the outer surface of the bumper body 10. Immediately afterwards, use a vacuum pump to extract the air on the side of the bumper body 10 away from the covering film 20. During this process, the covering film 20 gradually adheres to the outer surface of the bumper body 10. After the covering film 20 is completely adhered to the bumper body 10, turn off the vacuum pump. After the covering film 20 cools down, trim the covering film 20. Thus, the production of the bumper 100 is completed.
