[0002] The electric rear wing is usually installed at the rear of the car, and its main function is to increase downforce. When the vehicle reaches a certain speed, the electric rear wing opens, thereby generating downforce in the rear wing area, allowing the car to have greater grip and effectively reducing the air resistance generated by the car during high-speed driving.
[0003] In the design process of the electric rear wing in the related art, in order to form a whole with the rear of the car, its surface is generally flush with the surface of the rear structure in the vertical direction, and the electric rear wing at the rear is tilted downwards of the car. Although this design can reduce part of the overall wind resistance, turbulence will still be generated at the rear of the car during driving, resulting in an increase in the wind resistance coefficient. Utility Model Content
[0004] Based on this, it is necessary to provide an electric rear wing and a vehicle thereof that can reduce wind resistance, reduce fuel consumption or power consumption.
[0005] In order to solve the above technical problems, this application provides the following technical solutions:
[0006] An electric rear wing of a car comprises a rear wing plate, wherein along the vertical direction of the car, the rear wing plate has a first surface and a second surface which are arranged opposite to each other, and the second surface is relatively located above the first surface;
[0007] The second surface includes a connecting surface and a curved surface connected in sequence, and along the front-rear direction of the automobile, the curved surface is relatively located behind the connecting surface and extends to an end relatively far away from the connecting surface, and the end of the curved surface far away from the connecting surface is bent upward along the vertical direction of the automobile;
[0008] A tangent line of the arc surface is drawn through an end point of the arc surface away from one end of the connecting surface, and the tangent line intersects the first surface with an angle of θ1, 20 degrees ≤ θ1 ≤ 40 degrees.
[0009] In one embodiment, the tail wing panel has a folded state and an unfolded state; wherein, when the tail wing panel is in the folded state, the angle between the tangent and the horizontal plane is configured to be θ2, 0 degrees < θ2 ≤ 10 degrees.
[0010] In one embodiment, when the tail wing panel is in a folded state, the angle θ2 between the tangent line and the horizontal plane is configured to have a value range of 0 degrees < θ2 ≤ 5 degrees.
[0011] In one embodiment, when the tail wing panel is in the unfolded state, the angle between the tangent line and the horizontal plane is configured to be θ3, 10 degrees < θ3 < 20 degrees.
[0012] In one embodiment, the first surface includes a first surface, a second surface and a third surface connected in sequence along the front-rear direction of the automobile;
[0013] The surface of the first surface extending toward the rear of the vehicle is defined as the extension surface, the second surface and the third surface form a lap joint groove that is concave upward along the vertical direction of the vehicle, and the end of the third surface away from the second surface is defined as the lap joint end;
[0014] Wherein, along the vertical direction of the automobile, the overlapping end is located above the extension surface.
[0015] In one embodiment, the first surface extends along the front-rear direction of the automobile and gradually slopes downward in the vertical direction of the automobile.
[0016] In one embodiment, a chamber is disposed inside the tail wing panel.
[0017] In one embodiment, the electric rear wing of the automobile further includes a driving member and a lifting structure, one end of the lifting structure is connected to the rear wing panel, and the other end is connected to the driving member, so that the rear wing panel can be folded or unfolded in a vertical direction through the lifting structure under the drive of the driving member.
[0018] In one embodiment, the lifting structures are configured to be multiple in number, and the multiple lifting structures are arranged at intervals along the width direction of the car.
[0019] This application also provides the following technical solutions:
[0020] A vehicle comprises the electric rear wing of the vehicle described in any one of the above embodiments.
[0021] Compared with the prior art, the electric rear wing of the automobile and the automobile thereof are configured by bending the end of the arc surface away from the connection surface upward, so that a small rear wing structure is formed at the rear of the automobile, which can dredge and guide the airflow at the rear of the automobile at any time to change the flow direction and speed of the airflow, so that the airflow can pass through the vehicle body smoothly, so as to reduce the generation of vortices at the rear of the automobile, thereby reducing the drag coefficient and reducing fuel consumption or power consumption. At the same time, the value of θ1 cannot be too small or too large. If it is too small, it cannot guide the wind, and if it is too large, it will form resistance to the flow of wind. Therefore, the value of θ1 is set within the range of [20 degrees, 40 degrees], so that the arc surface can effectively dredge the airflow, thereby further reducing the drag coefficient.

[0038] like Figure 1As shown, the present application provides an electric rear wing 100 for a car. Along the length direction x (i.e., the front-to-back direction) of the car, the car has a relative front end and rear end, the front end is the front part of the car, and the rear end is the rear part of the car. The electric rear wing 100 for the car is arranged at the rear end of the car and serves as the end of the rear end of the car to constitute a part of the rear end of the car. It should be noted that the electric rear wing 100 for the car of the present application is integrally overlapped on the car taillight 200 in the vertical direction z, and the end of the rear end of the car is the end of the electric rear wing 100 for the car.
[0039] Specifically, Figure 2 and Figure 5 The electric rear wing 100 of the automobile comprises a rear wing plate 10. In the vertical direction z of the automobile, the rear wing plate 10 has a first surface 11 and a second surface 12 which are arranged opposite to each other. The first surface 11 is relatively located above the second surface 12; that is, the first surface 11 is arranged upward, and the second surface 12 is arranged downward. The second surface 12 comprises a connecting surface 121 and a curved surface 122 which are connected in sequence. Along the front-back direction of the automobile, the curved surface 122 is relatively located behind the connecting surface 121 and extends to an end relatively far away from the connecting surface 121, and the end of the curved surface 122 away from the connecting surface 121 is bent upward along the vertical direction of the automobile. In this way, by setting the end of the curved surface 122 away from the connecting surface 121 to bend upward, a small rear wing structure is formed at the rear of the automobile, which can guide and direct the airflow at the rear of the automobile at any time to change the direction and speed of the airflow, so that the airflow can pass through the vehicle body smoothly, so as to reduce the generation of vortices at the rear of the automobile, thereby reducing the wind resistance coefficient and reducing fuel consumption or power consumption.
[0040] As shown in 7, Figure 7 This is a fluid simulation diagram of the electric rear wing installed on the car. In the figure, Side means the side, Side = 0.0mm, and it means the x-section view of the car in the length direction of the car, and the section position is the center line position of the car in the width direction. Velocity means speed, Magnitude means size, the unit is m / s, and different colors indicate the speed of the airflow (from blue to red, the speed increases in sequence). Figure 7From the analysis, it can be known that the sources of the airflow at the rear of the car are the top and the bottom of the car, and the top airflow and the bottom airflow will form a vortex at the rear of the car. In the present embodiment, since the end of the arc surface 122 away from the connecting surface 121 is bent upward, the airflow will change direction and speed when passing through the rear, so that the intersection position of the top airflow and the bottom airflow changes, thereby changing the position of the vortex. Compared with the existing electric rear wing at the rear that tilts downwardly of the car, the vortex formed by the bottom airflow and the top airflow is away from the rear of the car and is relatively close to the bottom of the car. In this way, a vacuum area will be formed at the rear of the car, so that the pressure at the rear is relatively large, that is, the drag coefficient is relatively high. In the present application, from Figure 7 It can be seen that the vortex is formed near the rear of the car and is located in the middle of the car in the vertical direction. The airflow speed is about 7-9m / s, which forms a positive pressure at the rear of the car, thereby improving the airflow at the rear and effectively reducing the overall drag coefficient.
[0041] In one embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, a chamber 101 is provided inside the tail wing plate 10. Thus, the inside of the tail wing plate 10 is in a hollow state, which effectively reduces the weight of the tail wing plate 10 and is conducive to lightweighting.
[0042] like Figure 2 and Figure 3 As shown, the first surface 11 extends along the front-rear direction x of the vehicle and gradually slopes downward in the vertical direction z of the vehicle. In this way, the first surface 11 is arranged in an inclined plane, so that a slope channel is formed there, which is more conducive to guiding wind, rain, etc. to flow through the first surface 11 and increasing the speed of rain, wind, etc. flowing therethrough.
[0043] In one embodiment, if Figure 5 As shown, the first surface 11 includes a first surface 112, a second surface 113 and a third surface 114 connected in sequence along the front-rear direction x of the car; the surface of the first surface 112 extending toward the rear direction of the car is defined as an extension surface 111, and a lap groove 115 that is concave upward along the vertical direction z of the car is formed between the second surface 113 and the third surface 114, and an end of the third surface 114 away from the second surface 113 is defined as a lap end 116; wherein, along the vertical direction z of the car, the lap end 116 is located above the extension surface 111. In this way, when the tail wing panel 10 is in the unfolded state, during the driving process of the car, the wind or rain moving along the first surface 112 will not be blocked by the end of the third surface 114, thereby avoiding the formation of vortices at the rear of the tail wing panel 10. Here, the lap end 116 is the end of the rear of the car, and it is overlapped on the taillight 200 of the car in the vertical direction z.
[0044] In one embodiment, the shape of the connecting surface 121 matches the back of the car and serves as an extension of the back, thus forming the back shape of the car as a whole.
[0045] Preferably, the connection surface 121 is configured as a plane or a curved surface.
[0046] like Figure 3 , Figure 6 and Figure 7 As shown, the end point A of the arc surface 122 away from the connecting surface 121 is a tangent of the arc surface 122, and the tangent is configured as a tangent L. The tangent L intersects with the first surface 11 at an angle of θ1, 20 degrees ≤ θ1 ≤ 40 degrees. It can be understood that the value of θ1 cannot be too small or too large. If it is too small, the wind will be blocked when passing through the arc surface 122, thereby increasing the wind resistance. If it is too small, the wind guiding effect of the arc surface 122 is reduced, and the purpose of reducing wind resistance cannot be achieved. Therefore, in this embodiment, combined with Figure 7 , set θ1 to [20 degrees, 40 degrees], which can guide the airflow smoothly and change the airflow position and speed, thereby reducing wind resistance.
[0047] For example, the value of θ1 may be 20 degrees, 22 degrees, 25 degrees, 28 degrees, 30 degrees, 32 degrees, 35 degrees, 37 degrees, 40 degrees, etc. Of course, it is not limited thereto, and within the range of θ1, the value of θ1 may be selected and set according to actual needs.
[0048] like Figure 3 As shown, the tail wing panel 10 has a folded state and an unfolded state. When the tail wing panel 10 is not needed, it is in the folded state. When it is needed, the tail wing panel 10 can be unfolded.
[0049] Back to Figure 3 , when the tail wing panel 10 is in the folded state, the angle between the tangent line L and the horizontal plane a is configured to be θ2, 0 degrees <θ2 ≤ 10 degrees. In this way, at the rear position of the car, the tail wing panel 10 is tilted upward in the vertical direction, so that a small tail wing structure is always formed at the rear position of the car, which guides the airflow, allows the airflow to pass smoothly through the car body, and changes the position and speed of the airflow, thereby reducing wind resistance. That is, at this angle, when the tail wing panel 10 is in the folded state, the curved surface 122 can better guide the wind, allowing the wind to flow smoothly through the car body, thereby reducing wind resistance and wind noise, and reducing power consumption or fuel consumption.
[0050] Exemplarily, the value of θ2 can be 0.2 degrees, 0.5 degrees, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, etc. Of course, it is not limited thereto, and within the range of θ2, the value of θ2 can be selected and set according to actual needs.
[0051] Preferably, when the tail wing panel 10 is in the folded state, the value range of the angle θ2 between the tangent line L and the horizontal plane a is set to 0 degrees < θ2 ≤ 5 degrees. Within this range, it is more conducive to ensuring that the wind flows smoothly through the vehicle body.
[0052] like Figure 6 and Figure 7 As shown, when the tail wing panel 10 is in the unfolded state, the angle between the tangent line L and the horizontal plane a is configured as θ3, 10 degrees <θ3 <20 degrees. At this angle, when the tail wing panel 10 is in the unfolded state, the curved surface 122 can better guide the airflow and change the airflow position and speed, thereby reducing wind resistance, wind noise, and power or fuel consumption.
[0053] Exemplarily, the value of θ3 may be 11 degrees, 12 degrees, 13 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, etc. Of course, it is not limited thereto, and within the range of θ3, the value of θ3 may be selected and set according to actual needs.
[0054] like Figure 2 , Figure 4 and Figure 5 As shown, the electric rear wing 100 of the automobile further includes a driving member 21 and a lifting structure 22, wherein the driving member 21 is mounted on the rear panel 300 of the automobile. The lifting structure 22 is connected to the driving member 21 and is connected to the rear wing panel 10. Thus, under the drive of the driving member 21, the lifting structure 22 can drive the rear wing panel 10 to rise and fall in the vertical direction z, so that the rear wing panel 10 can switch between the unfolded state and the folded state.
[0055] Here, the driving member 21 can be configured as a power member such as a motor, a telescopic cylinder, etc. In this embodiment, the driving member 21 is configured as a motor.
[0056] In one embodiment, the number of the lifting structures 22 is multiple, and the multiple lifting structures 22 are arranged at intervals in the width direction of the car. The driving member 21 is connected to the multiple lifting structures 22, so as to drive the multiple lifting structures 22 synchronously.
[0057] It should be explained that the provision of multiple lifting structures 22 can effectively support the tail wing panel 10 and can also improve the stability of the lifting of the tail wing panel 10. At the same time, the use of a driving member 21 to simultaneously drive multiple lifting structures 22 can well ensure the stability and synchronization of the movement of the tail wing panel 10. Furthermore, the multiple lifting structures 22 are arranged at intervals in the width direction y, which is large for the span of the driving member 21 and is not conducive to the transmission of the power of the driving member 21. Therefore, here, the transfer is achieved through a flexible shaft, so that the power of the driving member 21 is transmitted, which effectively improves the stability of the power output of the driving member 21 and the reliability of the movement of the tail wing panel 10.
[0058] Here, the number of the lifting structures 22 can be set to two, three or four, etc. Of course, it is not limited thereto, and the specific number of the lifting structures 22 can be set according to actual needs. In addition, the lifting structure 22 can be a multi-link structure, a telescopic structure, etc.
[0059] like Figure 1 As shown, the present application also provides a car, which has the electric rear wing 100 of any of the above embodiments.
[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
