Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to a three-section electric tail wing lifting device. Background Technology

[0002] In the modern automotive field, with increasing vehicle speeds and growing demands for energy conservation, automotive aerodynamics has become increasingly crucial. When a car travels at high speeds, the airflow over the vehicle body generates complex forces. In particular, the airflow is faster and has lower pressure on the upper part of the car, while the airflow is slower and has higher pressure on the lower part. The resulting lift reduces tire-to-ground friction, leading to decreased vehicle handling and stability, and in severe cases, endangering driving safety. While both fixed and two-stage rear wings can adjust airflow direction, fixed rear wings are not adjustable, offering a single mode suitable for all speeds, resulting in poor low-speed performance, increased wind resistance, and wasted energy. Two-stage rear wings, although adjustable, have limited wingspan and cannot meet the safety requirements of high-speed scenarios. Utility Model Content

[0003] The present invention aims to solve the above-mentioned defects and provide a three-section electric tail wing lifting device.

[0004] In order to overcome the defects in the background technology, the technical solution adopted by this utility model to solve its technical problem is: this three-section electric tail wing lifting device includes a three-section electric tail wing mechanism composed of a left spoiler, a fixed plate and a right spoiler, and also includes a drive mechanism that controls the left spoiler and the right spoiler to move from the fixed plate to both sides and then merge to move above the fixed plate, and the fixed plate is fixed in position.

[0005] According to another embodiment of the present invention, the drive mechanism further includes a tray compartment, two small trays connected in the tray compartment, a drive bracket, a gearbox housing, and a motor. The two small trays are symmetrically arranged on both sides of the drive bracket. The gearbox housing and the motor are fixedly connected to the drive bracket. One of the small trays is connected to a follower swing arm and a drive swing arm, and is connected to the left spoiler tray through the follower swing arm and the drive swing arm. The other small tray is also connected to a follower swing arm and a drive swing arm, and is connected to the right spoiler tray through the follower swing arm and the drive swing arm.

[0006] According to another embodiment of the present invention, the motor is further connected to a rotating mechanism with the same structure on both sides of the gearbox housing via the gearbox housing. The rotating mechanism includes a turbine drive rod, which meshes with the motor via the gearbox housing. The turbine drive rod is connected to a lead screw via a spline coupler. The lead screw is connected to a driver via a bushing and is connected to a gear mechanism within the driver.

[0007] According to another embodiment of the present invention, the driver further includes an upper driver housing and a driver housing base, and a gear mechanism located within the upper driver housing and the driver housing base.

[0008] According to another embodiment of the present invention, the left spoiler is fixed on the left spoiler support plate, the right spoiler is fixed on the right spoiler support plate, and the fixing plate is fixed on the upper end of the driver bracket.

[0009] The beneficial effects of this utility model are as follows: This three-section electric tail wing lifting device adopts a drive mode combining rectangular gears and sector gears as the lifting mechanism of the three-section tail wing. The mechanical structure is simple and reliable, reducing production costs and subsequent maintenance costs, and further reducing the application cost of the three-section tail wing. The sufficient wingspan area forms a sufficient pressure difference on the upper and lower surfaces of the tail wing, providing additional downforce for the vehicle, increasing tire grip, and improving the stability of the vehicle at high speeds. At low speeds, the three-section tail wing is retracted, reducing the drag coefficient and improving the energy efficiency. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.

[0013] like Figure 1 , 2 As shown in the figure, the device includes a three-section electric tail wing mechanism consisting of a left spoiler 22, a fixed plate 8, and a right spoiler 24. It also includes a drive mechanism that controls the left spoiler 22 and the right spoiler 24 to move from the fixed plate 8 to both sides and then merge back to move above the fixed plate 8. The fixed plate 8 is fixed in position.

[0014] Preferred columns, such as Figure 3 , 4 As shown, the drive mechanism includes a tray compartment 23, two small trays 3 connected within the tray compartment 23, a drive bracket 12, a gearbox housing 9, and a motor 10. The two small trays 3 are symmetrically arranged on both sides of the drive bracket 12. The gearbox housing 9 and the motor 10 are fixedly connected to the drive bracket 12. One small tray 3 is connected to a follower arm 1 and a drive arm 6, which connect to the left spoiler tray 2. The other small tray 3 is also connected to a follower arm 1 and a drive arm 6, which connect to the right spoiler tray 21. The left spoiler 22 is fixed to the left spoiler tray 2, and the right spoiler 24 is fixed to the right spoiler tray 21. A fixing plate 8 is fixed to the upper end of the drive bracket 12. The drive mechanism rotates the drive arms 6 on both sides, causing the left spoiler tray 2 and the right spoiler tray 21 to unfold and retract.

[0015] Specifically, the motor 10 is connected to a rotating mechanism with the same structure on both sides of the gearbox housing 9 via the gearbox housing 9. The rotating mechanism includes a turbine drive rod 11, which meshes with the motor 10 via the gearbox housing 9. The turbine drive rod 11 is connected to the lead screw 7 via a spline coupler 13. The lead screw 7 is connected to the driver 25 via a bushing 16 and is connected to the gear mechanism inside the driver 25.

[0016] Preferred columns, such as Figure 5 As shown, the driver 25 includes an upper driver housing 4 and a driver housing base 17, as well as a gear mechanism located within the upper driver housing 4 and the driver housing base 17. The gear mechanism includes rectangular teeth 15 and sector teeth 14. The rectangular teeth 15 mesh with the sector teeth 14. The rectangular teeth 15 are connected to a slide rail 18 located in the upper part of the upper driver housing 4. The rectangular teeth 15 can slide on the slide rail 18. A lead screw nut 19 is embedded in the rectangular teeth 15. The lead screw nut 19 is connected to the lead screw 7. A sector tooth connecting rod 5 is connected to the sector teeth 14. The sector tooth connecting rod 5 has splines at both ends and is connected to the spline groove 20 at the lower end of the drive swing arm 6 through the splines. The sector tooth connecting rod 5 is connected to the small support plate 3 through a bushing. The upper part of the driver housing base 17 is connected to the upper driver housing 4, and the small support plate 3 is connected to the driver housing base 17. The lead screw nut 19 converts the rotational motion of the lead screw 7 into linear motion, driving the rectangular tooth 15 to move linearly along the slide rail 18 inside the drive upper housing 4. The linear motion of the rectangular tooth 15 drives the sector tooth 14 and the sector tooth connecting rod 5 at a small angle through the lower tooth groove. The sector tooth connecting rod 5 drives the drive swing arm 6 to rotate at a small angle, thereby causing the left spoiler support plate 2 and the right spoiler support plate 21 to unfold and retract. The lead screw nuts 19 on the left and right sides rotate in opposite directions, so that when the turbine drive rod 11 rotates in one direction, the drive swing arms 6 on both sides rotate to the sides.

[0017] When the three-section tail fin deploys: When the vehicle is traveling at high speed, the motor 10 drives the turbine drive rod 11 to rotate, which drives the drive swing arm 6 to rotate outward at a small angle through the lead screw nut 19 and rectangular gear 15. This causes the small support plates 3 on the left and right sides to move outward, thereby causing the left spoiler 22 and the right spoiler 24 to unfold, increasing the contact area between the rear wing and the airflow. The fixed plate 8 remains in place. The unfolded left spoiler 22 and right spoiler 24 change the direction of airflow, thereby reducing wind resistance and increasing the downforce of the vehicle, improving the vehicle's tire grip and vehicle stability.

[0018] When the three-section tail fin retracts: When the vehicle is traveling at low speed: the motor 10 rotates in the opposite direction, which is the opposite of the deployment logic, thereby causing the left spoiler 22 and the right spoiler 24 to retract, reducing the contact area between the rear wing and the airflow, thereby reducing wind resistance and reducing the vehicle's energy consumption.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
