Description

Technical Field

[0001] The utility model relates to the field of electric vehicle shells, in particular to an electric vehicle plastic shell capable of reducing wind resistance. Background Art

[0002] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Electric vehicles usually refer to vehicles that use batteries as energy sources and convert electrical energy into mechanical energy through controllers, motors and other components to control the current size to change the speed. Currently, there are various designs of electric vehicle plastic parts;

[0003] Taking aerodynamic factors into consideration in the prior art, the front face design of electric vehicles is mostly an arc-shaped curved surface design, which can reduce wind resistance to a certain extent and improve the stability of electric vehicle driving. However, relying solely on the arc-shaped front fender structure is not enough to achieve a good effect of reducing wind resistance. When riding, the front airflow will still directly act on the front face fender of the electric vehicle. If the airflow cannot be effectively broken and guided, it will still lead to problems such as large power loss and poor riding stability. The existing electric vehicle shell does not have the ability to disturb the side and rear end airflow, and cannot assist in bypassing and guiding the airflow based on the arc-shaped front face and body, resulting in a large wind resistance when riding. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content

[0025] The second cone wheel 57 can be driven to rotate by the motor 58, and the second cone wheel 57 drives the first cone wheel 56 to rotate, thereby driving the rotating shaft 52 and the spoiler 53 to rotate. The spoiler 53, the rear tilt plate 54 and the diverter plate 55 can be used to process the airflow around the outer shell of the electric vehicle, effectively reducing its wind resistance and improving its riding energy consumption and speed.

[0026] Preferably, the wind-breaking assembly 6 comprises a mounting column 61 and a wind-breaking cone 62, each of which is provided with a mounting hole 63, and a fixing bolt 64 is provided in the mounting hole 63. The mounting column 61 is provided with two groups and is fixed to the front end of the front shield 4. The wind-breaking cone 62 is sleeved on the mounting column 61 from front to back and the rear end is attached to the front shield 4. A plurality of guide grooves 65 are provided on the outer wall of the wind-breaking cone 62.

[0027] The wind-breaking cone 62 is conveniently installed through the mounting column 61 and the mounting hole 63, and is fixed and limited by the fixing bolt 64.
