Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to an electric rear wing mechanism that can retract into the vehicle body. Background Technology

[0002] An electric rear wing for automobiles is an aerodynamic component that uses a motor to drive the rear wing panel to rise and fall; an electric rear wing can enhance vehicle stability. When the vehicle speed reaches the wing's rise speed, the wing can rise automatically or be manually raised by the driver. In existing technology, electric rear wings are installed in recesses in the vehicle body, with the wing exposed to the outside of the vehicle. In rainy weather, rainwater can flow into these recesses and cannot drain away in time, eventually causing rust at the wing's connection points and the lifting structure.

[0003] Chinese Patent Publication No. CN202510595570.8, published on June 27, 2025, discloses an electric rear wing for automobiles. This patent utilizes a combination of a first-stage and a second-stage lifting mechanism assembly to achieve multi-stage opening of the rear wing, resulting in a high lifting height and a large tilting angle. However, this type of rear wing is directly exposed to the external environment. When the vehicle is driven in rainy weather, rainwater can enter the first-stage and second-stage lifting mechanisms, as well as the connection between the rear wing and the vehicle. Over time, these components are prone to rust or damage. Summary of the Invention

[0004] This invention primarily addresses the problem of existing automotive rear wings being directly exposed to the external environment and susceptible to water damage. It provides an electric rear wing mechanism that retracts into the vehicle body. By incorporating a mounting slot, the rear wing panel and mounting components are completely housed, preventing rainwater from entering them. Furthermore, the mounting components allow for the control of the rear wing panel to automatically move into and out of the mounting slot.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An electric rear wing mechanism capable of retracting into the vehicle body includes:

[0007] Tail fin;

[0008] The mounting assembly includes a mounting frame, a fixed frame, and a worm gear drive mechanism. The tail fin is connected to the mounting frame. The mounting frame is slidably mounted on the fixed frame in a front-to-back direction. The worm gear drive mechanism is used to drive the mounting frame to reciprocate on the fixed frame.

[0009] The mounting slot is located at the rear of the vehicle, the mounting component is located within the mounting slot, and the rear wing can be completely retracted into the mounting slot.

[0010] In this design, a worm gear drive mechanism moves the tail wing into and out of the mounting slot. In rainy or snowy weather, a telescopic structure is activated to move the tail wing into the mounting slot. When the tail wing is needed, the worm gear drive mechanism is activated to move the tail wing into the mounting slot. Because the worm gear drive mechanism is completely inside the mounting slot, rainwater cannot contact the telescopic structure, and after the tail wing is moved into the mounting slot, rainwater will also not contact the tail wing, thus achieving the goal of preventing rainwater from contacting the electric tail wing mechanism.

[0011] Preferably, the worm drive mechanism includes a worm, a motor for driving the worm to rotate, two turbines respectively disposed at both ends of the worm, and two external threaded rods. The worm is arranged in a left-right direction, and both ends of the worm have teeth, each tooth corresponding to a turbine and meshing with the corresponding turbine. The external threaded rods are arranged in a front-back direction, each turbine corresponding to a different external threaded rod, and each turbine is rotatably mounted on its corresponding external threaded rod. The motor drives the worm to rotate, and the worm drives the turbine to move on its corresponding external threaded rod. At this time, the mounting bracket connected to the turbine moves with the turbine, thereby moving the tail fin into / out of the mounting slot. The turbine drive mechanism has a compact structure and runs smoothly. Furthermore, the worm and teeth have a self-locking function to prevent the tail fin from sliding on its own.

[0012] Preferably, the turbine is provided with a through hole, and the inner wall of the through hole is provided with an internal thread section that is adapted to the external thread rod.

[0013] Preferably, the fixing frame includes two bases spaced apart, the bases are arranged in the front-to-back direction, and the external threaded rods correspond one-to-one with the bases, with the external threaded rods being disposed on the corresponding bases.

[0014] Preferably, the base has a first groove for accommodating part of the externally threaded rod, and a bracket for mounting the externally threaded rod is provided in the first groove. By providing the first groove, the installation space for the externally threaded rod is saved, thereby reducing the overall footprint of the mounting assembly.

[0015] Preferably, the mounting bracket includes a horizontal section and symmetrically arranged bent sections on both sides of the horizontal section. The tail fin is detachably connected to the top of the bent sections, which slope outwards from bottom to top. The motor is located on the top surface of the horizontal section. The two ends of the bent sections correspond one-to-one with the ends of the worm gear, and each bent section has a first through hole for the corresponding worm gear teeth to pass through. By setting up the mounting bracket, the motor and synchronously drive the turbine are installed.

[0016] Preferably, a connecting block is provided on the outer side of the bent section, and a second through hole is provided on the connecting block. The axis of the second through hole is located on the same straight line as the axis of the first through hole, and a bearing adapted to the worm is provided in the second through hole.

[0017] Preferably, a connecting plate is provided at the top of the bent section, and the tail fin is connected to the connecting plate by a bolt assembly. By providing the connecting plate, the connection stability between the tail fin and the mounting bracket is improved.

[0018] Preferably, the bottom surface of the tail fin is provided with a second groove corresponding to the motor, and part of the motor is located in the second groove.

[0019] Preferably, the height of the mounting groove is less than 30cm, the width of the mounting groove is less than 70cm, and the length of the mounting groove is less than the width of the vehicle body.

[0020] The principle and beneficial effects of this utility model that adopts the above technical solution are as follows:

[0021] 1. The electric tail wing mechanism can be completely retracted into the mounting slot. In rainy weather, rainwater will not come into contact with any part of the electric tail wing, avoiding the impact of rainwater on the tail wing and mounting components, and improving the service life of the electric tail wing structure.

[0022] 2. The worm gear drive mechanism ensures a compact overall structure for the installation components, while also providing smooth operation and low noise. Attached Figure Description

Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0033] In this embodiment, "front, back, left, and right" refers to the directions from the driver's perspective; "up and down" refers to the height of the vehicle itself.

[0034] The specific embodiments of this utility model are as follows:

[0035] like Figures 1 to 5 As shown, this utility model provides an electric rear wing mechanism that can retract into the vehicle body, including a rear wing plate 1, a mounting assembly, and a mounting slot 20; the mounting assembly includes a mounting frame 2, a fixed frame, and a worm gear 5 drive mechanism 4. The rear wing plate 1 is connected to the mounting frame 2, and the mounting frame 2 is slidably mounted on the fixed frame in the front-rear direction. The worm gear 5 drive mechanism 4 is used to drive the mounting frame 2 to reciprocate on the fixed frame. The worm gear 5 drive mechanism 4 includes a worm gear 5, a motor 6 for driving the worm gear 5 to rotate, two turbines 7 respectively disposed at both ends of the worm gear 5, and two external threaded rods 8; the worm gear 5 is arranged in the left-right direction, and both ends of the worm gear 5 have teeth 9, which correspond one-to-one with the turbines 7 and mesh with the corresponding turbines 7; the external threaded rods 8 are arranged in the front-rear direction, and the turbines 7 correspond one-to-one with the external threaded rods 8, with the turbines 7 rotatably mounted on the corresponding external threaded rods 8; the mounting slot 20 is disposed at the rear of the vehicle, the mounting assembly is located in the mounting slot 20, and the rear wing plate 1 can be completely retracted into the mounting slot 20.

[0036] In this design, the mounting slot 20 is located at the rear end of the vehicle body 21. The worm gear 5 drives the mechanism 4 to move the rear wing 1 into / out of the mounting slot 20. In rainy or snowy weather, the telescopic structure is activated to move the rear wing 1 into the mounting slot. When the rear wing 1 is needed, the motor 6 drives the worm gear 5 to rotate, and the worm gear 5 drives the turbine 7 to move on the corresponding external threaded rod 8. At this time, the mounting bracket 2 connected to the turbine 7 moves with the turbine 7, thereby moving the rear wing 1 into / out of the mounting slot. The turbine 7 drive mechanism has a compact structure and runs smoothly. At the same time, the worm gear 5 and the tooth 9 have a self-locking function to prevent the rear wing 1 from sliding on its own. Since the worm gear 5 drive mechanism 4 is completely located inside the mounting slot, rainwater cannot come into contact with the telescopic structure. After the rear wing 1 is moved into the mounting slot, rainwater will not come into contact with the rear wing 1, thus achieving the purpose of preventing rainwater from contacting the electric rear wing mechanism. In this embodiment, the shape of the mounting slot 20 is basically the same as the shape of the electric rear wing mechanism. The height of the mounting slot 20 is less than 30cm, the width of the mounting slot 20 is less than 70cm, and the length of the mounting slot 20 is less than the width of the vehicle body. That is, the electric rear wing mechanism can be completely retracted into the mounting slot 20. In other words, the overall size of the electric rear wing mechanism is small, which is reasonable for occupying space in the vehicle.

[0037] The turbine 7 has a through hole, and the inner wall of the through hole has an internal thread section that matches the external threaded rod 8. The turbine 7 is sleeved on the external threaded rod 8. When the teeth 9 of the worm gear 5 drive the turbine 7 to rotate forward / backward, the turbine 7 moves forward / backward along the external threaded rod 8. The fixing frame includes two bases 11 spaced apart, arranged in the front-back direction. The external threaded rod 8 corresponds to each base 11 and is set on the corresponding base 11. The base 11 has a first groove 12 for accommodating part of the external threaded rod 8, and a bracket 3 for installing the external threaded rod is provided in the first groove 12. By setting the first groove 12, the installation space of the external threaded rod 8 is saved, thereby reducing the overall footprint of the mounting assembly.

[0038] Mounting bracket 2 includes a horizontal section 13 and symmetrically arranged bent sections 14 on both sides of the horizontal section 13. The tail fin 1 is detachably connected to the top of the bent sections 14. The bent sections 14 slope outward from bottom to top. The motor 6 is located on the top surface of the horizontal section 13. The two ends of the bent sections 14 correspond one-to-one with the ends of the worm gear 5. The bent sections 14 are provided with first through holes 15 for the corresponding teeth 9 of the worm gear 5 to pass through. By setting up mounting bracket 2, the installation of motor 6 is realized and the synchronization of the movement of the two turbines is improved. In this embodiment, a connecting block 16 is provided on the outer side of the bent section 14. The connecting block is provided with a second through hole 17. The axis of the second through hole 17 is on the same straight line as the axis of the first through hole 15. A bearing adapted to the worm gear 5 is provided in the second through hole 17. By setting up the bearing, the transmission efficiency of the worm gear 5 is improved.

[0039] A connecting plate 18 is provided at the top of the bent section 14, and the tail fin 1 is connected to the connecting plate 18 by a bolt assembly. By setting the connecting plate 18, the connection points between the tail fin 1 and the mounting bracket 2 are increased, thereby improving the connection stability between the tail fin 1 and the mounting bracket 2.

[0040] The bottom surface of the tail fin 1 is provided with a second groove 19 corresponding to the motor 6, and part of the motor 6 is located in the second groove 19. By setting the second groove 19, the compactness of the tail fin 1 and the motor 6 is improved, and the space occupied by the tail fin 1 and the motor 6 is further reduced.

[0041] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
