Injection-molding tailgate of vehicle and vehicle

Abstract

The invention discloses an injection-molding tailgate of a vehicle. The injection-molding tailgate includes an outer decorative plate and an inner plate. The outer decorative plate and the inner plateare injection-molding pieces, and the inner plate includes a rear windshield body part and a door board part; the outer decorative plate is fixedly bonded with the door board part, the rear windshield body part includes inner edges and outer edges, reinforcement slots are formed between the inner edges and the outer edges of the two sides of the rear windshield body part, and the reinforcement slots are internally provided with reinforced separation plates in the length direction; V-shaped reinforcement ribs are arranged between the reinforced separation plates and the inner edges, straight-line-shaped reinforcement ribs are arranged at intervals between the reinforced separation plates and the outer edges, and the width of the reinforced separation plates, the width of the V-shaped reinforcement ribs and the width of the straight-line-shaped reinforcement ribs are all 1.2-1.4 mm. The injection-molding tailgate is light and high in strength, and the bright marks generated on the surface are reduced.

Description

technical field [0001] The invention relates to a vehicle tailgate and a vehicle, in particular to an injection molded tailgate of a vehicle and the vehicle. Background technique [0002] The tailgate of a traditional vehicle is similar to the body, and is made of a combination of metal skeleton, exterior sheet metal parts and injection-molded interior parts. The metal skeleton and the exterior sheet metal parts are connected together by welding. As a whole, due to the use of metal parts, there are disadvantages such as heavy weight, high price, low production efficiency, and large shape restrictions. In the prior art, there are also vehicle tailgates made of plastic through injection molding. The use of plastic materials can reduce the weight of the tailgate, which meets the requirements for lightweight vehicles. However, due to the difference in the strength of plastic materials and metals, it is necessary to The structure of the tailgate is improved. On the one hand, it...

Problems solved by technology

As a whole, due to the use of metal parts, there are disadvantages such as heavy weight, high price, low production efficiency, and large shape restrictions.

In the prior art, there are also vehicle tailgates made of plastic through injection molding. The use of plastic materials can reduce the weight of the tailgate, which meets the requirements for lightweight vehicles. However, due to the difference in the strength of plastic materials and metals, it is necessary to The structure of the tailgate is improved. On the one hand, it meets the strength requirements of the tailgate. On the other hand, it solves the problems of surface warping and appearance shrinkage that often occur in the injection molding process.
