Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle door technology, and in particular to a thin steel plate for new energy vehicle doors. Background Technology

[0002] With the increasing severity of the global energy crisis and environmental pollution, the market demand for new energy vehicles (NEVs), as a representative of environmentally friendly transportation, is growing rapidly. The door design of NEVs needs to meet higher environmental standards and energy efficiency requirements, while also allowing no compromise on safety performance. Therefore, automakers are constantly seeking new materials and processes to improve the lightweighting and performance optimization of vehicle doors.

[0003] In existing technologies, it is necessary to consider that the steel panel of the car door will heat up during hot seasons, and prolonged exposure to high temperatures will reduce the service life of the steel panel. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the reduced lifespan of car door steel panels due to the increased temperature during hot seasons. This invention proposes a thin steel plate for new energy vehicle doors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A thin steel sheet for new energy vehicle doors includes a steel sheet body formed by stamping a 0.8-2mm thin steel sheet, and further includes:

[0007] A corrosion-resistant layer is provided on the steel plate body, and a heat-resistant layer is provided on the corrosion-resistant layer. The four corners of the steel plate body are provided with arc-shaped edges to prevent bumps.

[0008] The heat dissipation component is located on the steel plate body and is used to dissipate heat from the steel plate body;

[0009] The water guiding component, located on the steel plate body, is used to drain water from the steel plate body.

[0010] Furthermore, the corrosion-resistant layer is a heat-resistant polymer formed of polyimide, which has high heat resistance and chemical corrosion resistance.

[0011] Furthermore, the heat-resistant layer is an organic coating, a protective film formed by polyurethane, to prevent the steel plate body from being corroded by corrosive media.

[0012] Furthermore, the heat dissipation component includes heat dissipation holes opened on the steel plate body near the edge. The bottom hole of the heat dissipation hole is a contraction opening, which is smaller than the heat dissipation hole to prevent foreign objects from entering the heat dissipation hole through the contraction opening.

[0013] Furthermore, a reinforcing plate is fixedly installed inside the heat dissipation hole. A flow collection hole is opened at the center of the reinforcing plate, and heat dissipation fins are provided around the inner ring of the heat dissipation hole. The heat dissipation fins are designed with an arc surface and are also used for air guiding.

[0014] Furthermore, the water guiding component includes a straight water collecting groove disposed on the surface of the steel plate body, and the steel plate body is provided with a plurality of arc-shaped water guiding grooves communicating with the straight water collecting groove.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] 1. This solution utilizes arc-shaped heat dissipation fins that are closely attached to the inner wall of the heat dissipation hole to guide heat towards the center of the heat dissipation hole towards the contraction opening. Then, the heat can be discharged through the collection hole and then through the contraction opening, thereby effectively dissipating heat and achieving a cooling effect.

[0017] 2. In this scheme, the water flow is guided from top to bottom through the arc-shaped water guide channel to the straight water collection channel. The setting of multiple arc-shaped water guide channels provides a buffer before the water is poured into the straight water collection channel, and the straight water collection channel is used to uniformly discharge the water, thereby achieving the drainage effect.

[0025] Example 1

[0026] Reference Figures 1-3 A thin steel sheet for new energy vehicle doors, comprising a steel sheet body 1 formed by stamping a thin steel sheet of 0.8-2mm thickness, and further comprising:

[0027] A corrosion-resistant layer 101 is provided on the steel plate body 1. A heat-resistant layer 102 is provided on the corrosion-resistant layer 101. The four corners of the steel plate body 1 are provided with arc-shaped edges 103 to prevent bumps. The corrosion-resistant layer 101 is a heat-resistant polymer formed by polyimide, which has a high heat resistance temperature and chemical corrosion resistance. The heat-resistant layer 102 is an organic coating formed by polyurethane to form a protective film to prevent the steel plate body 1 from being corroded by corrosive media.

[0028] In this embodiment, a heat dissipation component is disposed on the steel plate body 1 and is used to dissipate heat from the steel plate body 1. The heat dissipation component includes a heat dissipation hole 3 opened on the steel plate body 1 near the edge. The bottom hole of the heat dissipation hole 3 is a contraction opening 301, which is smaller than the heat dissipation hole 3 to prevent foreign objects from entering the heat dissipation hole 3 through the contraction opening 301. A reinforcing plate 4 is fixedly installed inside the heat dissipation hole 3. A flow collection hole 5 is opened at the center of the reinforcing plate 4, and heat dissipation fins 6 are provided around the inner ring of the heat dissipation hole 3. The heat dissipation fins 6 are arc-shaped and are also used for guiding the flow.

[0029] In this embodiment, the water guiding component is disposed on the steel plate body 1 and is used to guide the water on the steel plate body 1. The water guiding component includes a straight water collecting channel 2 disposed on the surface of the steel plate body 1, and the steel plate body 1 is provided with a plurality of arc-shaped water guiding channels 201 communicating with the straight water collecting channel 2. The water flow can enter the straight water collecting channel 2 through the trajectory of the arc-shaped water guiding channel 201 and be uniformly guided out, and has a buffering effect on the water flow before entering the straight water collecting channel 2.

[0030] The implementation principle of a thin steel plate for a new energy vehicle door in this application embodiment is as follows: The heat generated by the steel plate body 1 can enter the heat dissipation hole 3, and then the heat is guided to the center of the heat dissipation hole 3 towards the contraction opening 301 by the arc-shaped heat dissipation fins 6 that are close to the inner wall of the heat dissipation hole 3. Then, it can be guided to the contraction opening 301 through the collection hole 5 and discharged, thereby effectively dissipating the heat and achieving the cooling effect. When there is water on the steel plate body 1, it can be guided from top to bottom to the straight water collection channel 2 through multiple arc-shaped water guide channels 201. The setting of multiple arc-shaped water guide channels 201 has a buffering effect before the water is poured into the straight water collection channel 2. The water is discharged uniformly by the straight water collection channel 2, thereby achieving the drainage effect.

[0031] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0032] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
