It should be noted that, in the present embodiment, the plastic door bottom plate 1 and the housing 3 can be selected according to different vehicle types and requirements, and engineering plastics are generally used. Wherein, the English name of the engineering plastics is: engineering-plastics refer to industrial plastics used as industrial parts or housing materials, and are plastics excellent in strength, impact resistance, heat resistance, hardness, and aging resistance. It is defined in Japan as "a high-performance plastic which can be used for structural and mechanical parts, has a heat resistance of 100 ℃ or higher, and is mainly used industrially". Five common engineering plastics include: PC, PA, POM, PBT, PPE. With the development of automobiles towards light weight, the usage amount of plastics on automobiles is increasing, and particularly, automotive interior parts put higher demands on materials. By utilizing the characteristics of light weight, rust prevention, vibration absorption and large design freedom of plastics, the plastic structural member for the modern automobile is greatly developed and is one of the key development directions in the future. The amount of plastic used per car is one of the indicators for the technical level of car production. The average plastics used in developed countries such as japan, usa and germany is over 100 kg per car, and the average plastics accounts for 8% of the total weight of the car. The average plastic consumption of each automobile in China is 70 kg, and the average plastic consumption accounts for about 6 percent of the total weight of the automobile. Wherein the engineering plastic accounts for 10 percent of the total automobile plastic.
