A front fender for an electric vehicle and an electric vehicle

Abstract

This utility model discloses a front fender and electric vehicle, belonging to the technical field of electric vehicle accessories. The front fender includes a plate body with a windward side and a leeward side, both of which are non-planar. Side plates are also provided on both sides of the plate body. Each side plate includes a vertical plate, which is connected to the side of the plate body by several horizontal plates. The side of the plate body, the horizontal plates, and the vertical plates together form a ventilation area. The advantage of this utility model is that when the electric vehicle moves forward, the wind is dispersed to both sides of the plate body through the windward side, thus entering the ventilation area. When the wind passes through the ventilation area, it creates downward pressure, pressing the electric vehicle onto the road surface and improving the stability of the vehicle on the road.

Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, specifically to an electric vehicle front fender and an electric vehicle. Background Technology

[0002] In modern electric vehicle design, a front fender structure is often installed in the steering wheel area to reduce air resistance during driving. However, most front fenders in existing technology adopt a flat plate configuration, which directs airflow to the sides of the vehicle body when the vehicle is in motion. Due to the lack of aerodynamic guidance design on the surface of the front fender, airflow is prone to turbulence and separation when passing through it, resulting in a turbulent effect and consequently reducing vehicle driving stability. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a front fender and electric vehicle for electric vehicles, so as to solve the problem of decreased stability of vehicles during operation in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: On the one hand, the present invention provides a front fender for an electric vehicle, comprising: a plate body, the plate body having a windward side and a leeward side, both of which are non-planar, and side plates provided on both sides of the plate body; wherein, the side plate includes a vertical plate, the vertical plate and the side of the plate body are connected by several horizontal plates, and the side of the plate body, the horizontal plates and the vertical plate together form a ventilation area, and when the wind passes through the ventilation area, it forms downward pressure.

[0005] Optionally, the cross plate has a first plane and a first curved surface, the first curved surface extending toward the first plane and forming a first tip.

[0006] Optionally, the vertical plate has a second plane and a second curved surface, the second curved surface extending toward the second plane and forming a second tip.

[0007] Optionally, the second plane is located within the ventilation area.

[0008] Optionally, both the first tip and the second tip are acute angles.

[0009] Optionally, the windward surface has a forward protrusion in the middle, which extends to both sides of the windward surface to form two symmetrically arranged inclined surfaces.

[0010] Optionally, a plurality of evenly distributed guide grooves are provided on the inclined surface, and one end of the guide groove away from the front protrusion extends into the ventilation area.

[0011] Optionally, the plate body has a cavity, and a plurality of connecting parts connecting the windward side and the leeward side are fixed in the cavity.

[0012] Optionally, the area of ​​the windward side is larger than the area of ​​the leeward side.

[0013] On the other hand, this utility model also provides an electric vehicle, including a frame, on which a front baffle is fixed.

[0014] The beneficial effects of this utility model are as follows:

[0015] The plate of this utility model has a windward side and a leeward side. The windward side and the leeward side are non-planar designs, which can direct airflow to both sides of the vehicle during the vehicle's movement. At the same time, this utility model also designs ventilation areas on both sides of the plate, which are formed by vertical plates, horizontal plates and the side edges of the plate. When the airflow passes through the ventilation area, it will generate downward pressure, thereby pressing the vehicle to the ground and ultimately improving the stability of the vehicle during driving.

[0016] Meanwhile, the horizontal plate of this utility model has a first flat surface and a first curved surface, and the first pointed part formed by their mutual extension can separate the airflow. During the movement of the vehicle, the airflow velocity on the first flat surface is slow, so the pressure is high. The airflow velocity on the first curved surface is fast, so the pressure is low, which creates a pressure difference. The first flat surface is pressed against the first curved surface by atmospheric pressure, thereby forming a downward pressure, which ultimately presses the vehicle onto the ground.

[0017] Similarly, the second plane and the second curved surface of the vertical plate of this utility model will also generate the pressure difference mentioned above. When a crosswind is generated, the pressure difference will form a lateral pulling force opposite to the direction of the crosswind, which will offset part of the lateral thrust of the crosswind on the vehicle body, thereby reducing the deviation of the vehicle body and improving the stability of the vehicle during driving.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] As mentioned earlier, in modern electric vehicle design, a front fender structure is often installed in the steering wheel area to reduce air resistance during driving. However, most front fenders in existing technologies adopt a flat plate configuration, which directs airflow to the sides of the vehicle body when the vehicle is in motion. Due to the lack of aerodynamic guidance design on the surface of the front fender, airflow is prone to turbulence and separation when passing through it, resulting in a turbulent effect and consequently reducing vehicle driving stability.

[0029] To address this issue, this utility model provides a front fender and an electric vehicle. By modifying the front fender, a pressure difference is generated during vehicle movement to stabilize the vehicle, thereby solving the aforementioned problem. This utility model solves the problem in the following way.

[0030] Example 1:

[0031] Please refer to the instruction manual appendix. Figures 1 to 6As shown in the figure, this embodiment provides a front fender for an electric vehicle, which includes a body 1 and side panels 2. The body 1 has a windward surface 11 and a leeward surface 12, with a cavity 13 between the windward surface 11 and the leeward surface 12. Several connecting portions 14 are disposed within the cavity 13. The windward surface 11 faces forward, directly facing the airflow during vehicle movement. A forward protrusion 111 is provided in its middle, extending to both sides of the windward surface 11, thereby forming a... Figure 5 or Figure 6 The inclined surface is shown. Several evenly distributed guide channels 112 are also formed on this inclined surface. During vehicle movement, the inclined surface moves at high speed, generating airflow upon contact with the air. This airflow is then dispersed along the guide channels 112 to both sides of the plate 1 (as shown in the figure, airflow a is decomposed into airflow b directed towards both sides after contacting the inclined surface). The leeward surface 12 is a curved surface with an area smaller than the combined area of ​​the two inclined surfaces of the windward surface 11 and the guide channels 112. Therefore, its smaller area reduces the intensity of vortices behind the baffle, reducing the "dragging" sensation during vehicle movement, thereby reducing overall air resistance and increasing driving range. Simultaneously, the leeward surface 12 faces the driver and has a smaller area, reducing the amount of turbulence behind the baffle entering the driving area and preventing dust, leaves, and other debris from being carried into the vehicle by the airflow.

[0032] In this first embodiment, as... Figures 1 to 4 As shown, side plates 2 are provided on both sides of the plate 1. Each side plate 2 includes a vertical plate 22. The vertical plate 22 and the side of the plate 1 are connected by several evenly distributed horizontal plates 21. The side of the plate 1, the horizontal plates 21, and the vertical plates 22 enclose a ventilation area 3. The opening of the aforementioned guide groove 112 also extends into this ventilation area 3, thereby smoothly guiding the airflow into the ventilation area 3 (e.g., Figure 6 As shown, a portion of the airflow b enters the ventilation area 3, forming airflow c). When the airflow passes through the ventilation area 3, it creates downward pressure. This presses the front fender and the electric vehicle body onto the ground, making the electric vehicle more stable.

[0033] Example 2:

[0034] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 3 or Figure 4 As shown in this second embodiment, the horizontal plate 21 has a first flat surface 211 and a first curved surface 212. The first curved surface 212 extends toward the first flat surface 211 and forms a first pointed portion 213. The first pointed portion 213 is an acute angle. When the airflow touches the first pointed portion 213, it is split into two airflows. One airflow follows the direction shown in the figure. Figure 4 Proceeding in the direction of c (same) Figure 6 (c) of the airflow, and another part along such as Figure 4 The flow proceeds in the direction of 'e'. Since 'c' passes through a plane and 'e' passes through a curved surface, the flow velocity of 'c' is low and the pressure is high, while the flow velocity of 'e' is high and the pressure is low. This creates a pressure difference, resulting in pressure from the first plane 211 to the first curved surface 212. This pressure presses the vehicle against the ground during its movement, making the ride more stable.

[0035] The vertical plate 22 has a second plane 221 and a second curved surface 222. The second plane 221 is located within the ventilation area 3. The second curved surface 222 extends toward the second plane 221 and forms a second tip 223. The second tip 223 is also an acute angle. When the airflow touches the second tip 223, it is also divided into two airflows. Similarly, a pressure difference is generated during vehicle movement. This pressure difference generates a force from the second plane 221 to the second curved surface 222 (e.g., ...). Figure 6 As shown, the velocity of airflow c is less than that of airflow d, thus creating a pressure difference. This is reflected in plate 1 as outward pulling forces on both sides. When the vehicle encounters a crosswind, this pulling force will form a lateral pulling force opposite to the direction of the crosswind, which will offset part of the lateral thrust of the crosswind on the vehicle body, thereby reducing the vehicle body deviation and improving the stability of the vehicle during driving.

[0036] Example 3:

[0037] Based on the same general inventive concept, this utility model also provides an electric vehicle, which includes a frame on which the front baffle of the aforementioned embodiment is fixed. During the movement of the electric vehicle, the front baffle diverts airflow and generates downward and lateral forces, thereby making the electric vehicle more stable.

[0038] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to:

[0039] The plate 1 of this utility model has a windward surface 11 and a leeward surface 12. The windward surface 11 and the leeward surface 12 are non-planar designs, which can direct airflow to both sides of the vehicle during the vehicle's movement. At the same time, the utility model also designs ventilation areas 3 on both sides of the plate 1, which are formed by vertical plates 22, horizontal plates 21 and the sides of the plate 1. When the airflow passes through the ventilation area 3, it will generate downward pressure, thereby pressing the vehicle to the ground and ultimately improving the stability of the vehicle during driving.

[0040] Meanwhile, the horizontal plate 21 of this invention has a first flat surface 211 and a first curved surface 212, and the first pointed portion 213 formed by their mutual extension can separate the airflow. During vehicle movement, the airflow velocity on the first flat surface 211 is slow, resulting in high pressure. The airflow velocity on the first curved surface 212 is fast, resulting in low pressure, which creates a pressure difference. The first flat surface 211 is pressed against the first curved surface 212 by atmospheric pressure, thereby forming a downward pressure that ultimately presses the vehicle onto the ground.

[0041] Similarly, the second plane 221 and the second curved surface 222 of the vertical plate 22 of this utility model will also generate the above-mentioned pressure difference. When a crosswind is generated, the pressure difference will form a lateral pulling force opposite to the direction of the crosswind, which will offset part of the lateral thrust of the crosswind on the vehicle body, thereby reducing the deviation of the vehicle body and improving the stability of the vehicle during driving.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
