Description

Technical Field

[0001] The utility model relates to a spoiler for reducing the wind resistance of an electric vehicle when the vehicle is running at high speed, and belongs to the technical field of spoilers. Background Art

[0002] A car spoiler refers to a component similar to an inverted aircraft tail wing installed on the trunk lid of a car. On the one hand, the spoiler increases the dynamic appearance of the car, and on the other hand, it effectively reduces the air resistance generated by the vehicle during high-speed driving, which not only saves fuel but also improves the stability of the vehicle's driving. Especially for new energy vehicles, the role of the spoiler is more obvious and can reduce the car's power consumption.

[0003] After searching Chinese patent CN220281518U, a rear spoiler structure of an automobile is disclosed, comprising a spoiler body and a rear cover of a vehicle body, side panels are fixedly connected on both sides of the spoiler body, a guide groove is provided on the upper surface of the spoiler body, a fixing hole is provided on the spoiler body located on one side of the guide groove, and a lifting device is fixedly connected at the lower end of the fixing hole, the lifting device comprises a support rod and a base, the base is fixedly connected to the rear cover of the vehicle body, the upper end of the support rod is fixedly connected to the spoiler body, and the lower end is fixedly connected to the lifting plate, the two ends of the upper side of the base are fixedly connected to guide rods, the guide rods are slidably connected to guide blocks, and the upper end is fixedly connected to a pad block, the upper side of the pad block is fixedly connected to the top of the rear cover of the vehicle body, the two ends of the lifting plate are fixedly connected to one side of the guide block, the upper side of the base is fixedly connected to an electric push rod, and the upper end of the electric push rod is fixedly connected to the lower side of the lifting plate. Through the above structure, the height of the spoiler body can be adjusted to better reduce the lift of the rear end of the automobile.

[0004] Although the above-mentioned prior art can improve the effect of the spoiler by adjusting the height of the spoiler, it simply adopts an electric push rod to drive the spoiler to rise for adjustment, and its electric push rod is placed vertically. Since the electric push rod itself has a certain length, and its own length needs to be greater than the length of the distance it can be extended and retracted, the prior art needs to occupy too much space in the trunk. At the same time, the direction of the spoiler of the prior art cannot be adjusted, and it cannot effectively cope with situations when driving at different speeds.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a spoiler for reducing the wind resistance of an electric vehicle when driving at high speeds in order to solve the above-mentioned problem. The height of the spoiler can be adjusted quickly and conveniently, and the structure will not occupy too much space in the trunk. At the same time, the spoiler can also adjust the angle according to different driving speeds, which is beneficial to improving the actual use effect of the spoiler.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a spoiler for reducing the wind resistance of an electric vehicle when driving at high speed, comprising a fixed bottom plate and a supporting bottom plate, wherein a supporting base is respectively installed on the top outer wall of the fixed bottom plate, a bidirectional ball screw is rotatably connected to the supporting base, and a supporting slider is respectively connected to the bidirectional ball screw through a ball nut, and a supporting plate one and a supporting plate two are respectively rotatably connected to the two supporting sliders, and a supporting side plate is respectively installed on the bottom outer wall of the supporting bottom plate, and the supporting plate one and the supporting plate two are rotatably connected to the supporting side plate through a rotating shaft, and a fixed side plate is respectively installed on the bottom outer wall of the supporting bottom plate, and a supporting shaft is rotatably connected to the fixed side plate, and a supporting vertical plate is installed on the side wall of the supporting shaft, and a spoiler horizontal plate is installed on the supporting vertical plate.

[0008] Furthermore, in order to enable the two supporting sliding blocks to move in opposite directions, the threads at both ends of the bidirectional ball screw are in opposite directions.

[0009] Furthermore, in order to drive the ball screw to rotate, a driving motor 2 is installed on the top outer wall of the fixed base plate, and the output end of the driving motor 2 is connected to a driving gear 2. A driven gear 2 is installed at one end of the bidirectional ball screw, and the driving gear 2 is meshingly connected with the driven gear 2.

[0010] Furthermore, in order to drive the supporting vertical plate to rotate a certain angle, a driving motor 1 is installed on the bottom outer wall of the supporting base plate, and the output end of the driving motor 1 is connected to a driving gear 1, and a driven bevel gear is installed at one end of one of the supporting shafts, and the driven bevel gear is meshed and connected with the driving gear 1.

[0011] Furthermore, in order to guide and support the support base plate, which is beneficial to improving the stability of the support base plate when it is lifted or lowered, support vertical rods for guiding the support base plate are respectively installed on the top outer wall of the fixed base plate.

[0012] Furthermore, in order to prevent water from entering the rear of the car on rainy days, a sealing gasket is installed on the bottom outer wall of the spoiler plate.

[0013] Furthermore, in order to guide and cut the air, thereby reducing the wind resistance of the car when it is driving, spoiler side panels are respectively installed on the two side walls of the spoiler transverse plate.

[0014] Furthermore, in order to further improve the stability of the bidirectional ball screw during rotation, a supporting middle plate is installed on the top outer wall of the fixed base plate, and the supporting middle plate is rotatably connected to the bidirectional ball screw.

[0015] The technical effects and advantages of the utility model are as follows: the height of the spoiler horizontal plate can be adjusted by adjusting the height of the supporting bottom plate, and the height of the spoiler horizontal plate can be adjusted by adjusting the inclination angle of the supporting plate one and the supporting plate two, which not only ensures the working effect of the spoiler but also does not occupy too much space in the trunk; and when the spoiler horizontal plate is raised, the supporting vertical plate can be driven by the driving motor one to rotate a certain angle, so that the angle of the spoiler horizontal plate can be tilted, thereby enabling the spoiler to improve the effect of the spoiler according to different driving speeds.
