[0023] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a high-temperature resistant injection molded part for a vehicle engine compartment, including an engine compartment integrated housing 1. On the upper surface of the engine compartment integrated housing 1, there is a motor cavity 101. On both sides of the outer arc surface of the engine compartment integrated housing 1, there are convex portions 102. On the upper surface of the convex portion 102, there are positioning holes. On one side of the inner bottom wall of the engine compartment integrated housing 1, there are connecting through holes 103. On the side of the engine compartment integrated housing 1 away from the connecting through holes 103, there is a rectangular wire passing hole 104. The inner bottom wall of the engine compartment integrated housing 1 is movably connected with a nylon cover body 2. On the upper surface of the nylon cover body 2, there is a groove 201, and the groove 201 is adaptively connected with the engine compartment integrated housing 1. In the middle of the upper surface of the nylon cover body 2, there is an installation through hole 202. A rubber tube 203 is penetrated and connected in the installation through hole 202. The number of grooves 201 on the upper surface of the nylon cover body 2 is several, and they are evenly distributed on the surface of the nylon cover body 2 in the form of a rectangular array. The installation through hole 202 is in a stepped shape. One end of the rubber tube 203 penetrates to the outside of the connecting through hole 103 on the surface of the engine compartment integrated housing 1. The four corners of the nylon cover body 2 are all adapted to the inner wall of the engine compartment integrated housing 1. The material of the nylon cover body 2 is PA66.

[0024] By injection molding the nylon cover body 2 and the engine compartment integrated housing 1, the reliability and stability of the connection between the nylon cover body 2 and the engine compartment integrated housing 1 can be ensured. By using the nylon cover body 2 instead of the rubber cover body, the use of rubber materials can be reduced. Generally, the price of rubber materials is higher than that of nylon materials, reducing the use cost. At the same time, nylon has high heat resistance, wear resistance, aging resistance and other characteristics, and can fully meet the working requirements in the high-temperature environment inside the engine compartment.

[0025] On one side of the engine compartment integrated housing 1 close to the nylon cover body 2, there is a fixed installation plate 3. On both sides of the installation plate 3, there are fixed side plates 4. The number of side plates 4 is two, and the number of installation plates 3 is two. A rectangular structure is formed between the two side plates 4 and the two installation plates 3. Between the two installation plates 3, there are fixed heat dissipation fins 5. The number of heat dissipation fins 5 is several, and they are evenly distributed on both sides of the installation plate 3 in the form of a horizontal array. On the surface of one of the installation plates 3, there is a vehicle-mounted charger 6, and the output end of the vehicle-mounted charger 6 penetrates to the outside of the engine compartment integrated housing 1.

[0026] By fixing the heat dissipation fins 5 on one side of the engine compartment integrated housing 1, a heat dissipation effect can be achieved. That is, there may be gaps between the connection structures of the two, and heat will enter the interior of the connection structure through the gaps. Through the above structure, a certain heat dissipation effect can be achieved to a certain extent.

[0027] In the present utility model, the working steps of the device are as follows:

[0028] At the bottom of the engine compartment integrated housing 1, nylon cover bodies 2 perpendicular to the surface of the maneuvering cavity 101 are respectively provided. Threaded holes are respectively provided on the outward convex portions 102. Through the above structural design, it can be ensured that the connection through holes 103 on the rubber tube 203 and the nylon cover body 2 are fixedly installed in the engine compartment integrated housing 1, thereby ensuring the stability and reliability of the nylon cover body 2 during the driving of the vehicle. At the same time, the nylon cover body 2 and the engine compartment integrated housing 1 are injection molded, which can ensure the reliability and stability of the connection between the nylon cover body 2 and the engine compartment integrated housing 1. By using the nylon cover body 2 instead of the rubber cover body, the use of rubber materials can be reduced. Generally, the price of rubber materials is higher than that of nylon materials, reducing the use cost. At the same time, nylon has high heat resistance, wear resistance, aging resistance and other characteristics, and can fully meet the working requirements in the high-temperature environment in the engine compartment. A heat dissipation fin 5 is fixed on one side of the engine compartment integrated housing 1, which can play a heat dissipation role, that is, there may be gaps between the two connection structures, and heat will enter the interior of the connection structure through the gaps. Through the above structure, a certain heat dissipation effect can be achieved to a certain extent.
