Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a scissor-type electric rear wing for automobiles. Background Technology

[0002] A car rear spoiler is an aerodynamic component installed at the rear of a vehicle to improve driving stability, enhance handling performance, or reduce wind resistance. Currently, car rear spoilers are mainly divided into fixed spoilers and electric spoilers. These two types of spoilers are installed using several methods, including metal clip mounting, bolt assembly connection, and adhesive bonding. For metal clip mounting and bolt assembly connections, rainwater can seep into the metal clips or bolt connections in rainy weather, causing rust over time. Adhesive bonding is less stable than the other two methods, especially after water seeps into the bonded area, easily causing the spoiler to detach. Furthermore, fixed spoilers are directly exposed to the external environment, and electric spoilers are partially exposed, making them more susceptible to the effects of external debris and water. Summary of the Invention

[0003] This invention primarily addresses the problem that existing car rear wings are directly exposed to the external environment and are easily affected by external water flow and debris. It provides a scissor-type electric rear wing for automobiles, which, by setting a receiving groove, achieves complete storage of the rear wing structure, preventing rainwater from entering the telescopic structure and the rear wing; by setting a telescopic structure, it enables the rear wing to move into / out of the receiving groove on its own.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A scissor-type electric rear wing for automobiles includes:

[0006] Tail fin;

[0007] A telescopic structure, comprising a frame and a scissor assembly, wherein a tail fin is connected to the frame and the scissor assembly is used to drive the frame to move in a forward-backward direction;

[0008] A receiving slot is provided in the vehicle body, the telescopic structure is located in the receiving slot, and the receiving slot has an opening for the rear wing to extend out.

[0009] In this design, the tail fin is moved into and out of its receiving slot via a telescopic structure. In rainy or snowy weather, the telescopic structure is activated to move the tail fin into the receiving slot; when the tail fin is needed, the telescopic structure is activated to move it into the receiving slot. Because the telescopic structure is completely inside the receiving slot, rainwater cannot come into contact with it. Similarly, once the tail fin is inside the receiving slot, rainwater will not come into contact with it, thus achieving the goal of preventing rainwater from contacting the scissor-type electric tail fin.

[0010] Preferably, the frame includes a mounting rod arranged in a left-right direction, and two sliders are slidably mounted on the mounting rod. The tail fin is connected to the sliders. In actual operation, the scissor lift assembly drives the mounting rod to move back and forth, and the tail fin connected to the sliders moves synchronously with the mounting rod.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] The specific embodiments of this utility model are as follows:

[0034] like Figures 1 to 7 As shown, this utility model provides a scissor-type electric rear wing for automobiles, including a rear wing plate 1, a telescopic structure, and a receiving slot 4; the telescopic structure includes a frame 2 and a scissor assembly 3, the rear wing is connected to the frame 2, and the scissor assembly 3 is used to drive the frame 2 to move in the front-rear direction; the receiving slot 4 is set in the vehicle body, the telescopic structure is located in the receiving slot 4, and the receiving slot 4 has an opening for the rear wing plate 1 to extend out.

[0035] In this design, the rear wing 1 moves into / out of the receiving slot 4 via a telescopic structure. In rainy or snowy weather, the telescopic structure is activated to move the rear wing 1 into the receiving slot 4; when the rear wing 1 is needed, the telescopic structure is activated to move the wing into the receiving slot 4. Since the telescopic structure is completely inside the receiving slot 4, rainwater cannot contact the telescopic structure, and after the rear wing 1 is moved into the receiving slot 4, rainwater will also not contact the rear wing 1, thus achieving the goal of preventing rainwater from contacting the scissor-type electric rear wing. In this embodiment, the shape of the receiving slot 4 is basically the same as the shape of the scissor-type electric rear wing. The height of the receiving slot 4 is less than 30cm, the width of the receiving slot 4 is less than 70cm, and the length of the receiving slot 4 is less than the width of the vehicle body. This means the scissor-type electric rear wing can be completely retracted into the receiving slot 4, resulting in a smaller overall size of the scissor-type electric rear wing and reasonable space utilization on the vehicle.

[0036] like Figure 2As shown, in this embodiment, the frame 2 includes a mounting rod 6, which is arranged in the left-right direction. Two sliders 7 are slidably arranged on the mounting rod 6, and the tail wing plate 1 is connected to the sliders 7. The scissor lift assembly 3 includes a base 8, a forward and reverse lead screw 9, a cross link, a motor 27 for driving the forward and reverse lead screw 9 to rotate, and a forward slider 11 and a reverse slider 12 sleeved on the forward and reverse lead screw 9. The forward and reverse lead screw 9 is arranged in the left-right direction and includes a forward lead screw section 9a and a reverse lead screw section 9b. The forward slider 11 is located on the forward lead screw section 9a, and the reverse slider 12 is located on the reverse lead screw section 9b. The cross link includes a first rod 13 and a second rod 14 that are hinged to each other and form an X shape. The front end of the first rod 13 is hinged to one of the sliders 7, and the rear end of the first rod 13 is hinged to the reverse slider 12. The front end of the second rod 14 is hinged to the other slider 7, and the rear end of the second rod 14 is hinged to the forward slider 11. In actual operation, motor 27 drives the forward / reverse lead screw 9 to rotate forward / reverse, causing the forward slider 11 on the forward lead screw section 9a and the reverse slider 12 on the reverse lead screw section 9b to move away / closer to each other. Taking the forward rotation of the forward / reverse lead screw 9 driven by motor 27 as an example, the forward slider 11 on the forward lead screw section 9a and the upper reverse slider 12 on the reverse lead screw section 9b move closer to each other. The forward slider 11 and the reverse slider 12 push the first rod 13 and the second rod 14 respectively. At this time, the included angle between the first rod 13 and the second rod 14 becomes smaller, and the two sliders 7 at the front end of the first rod 13 and the second rod 14 also move closer to each other, causing the tail fin 1 to move forward until the tail fin 1 is completely removed from the receiving groove 4. Understandably, when it is necessary to retract the tail fin 1, the motor drives the forward / reverse lead screw 9 to rotate in the reverse direction. At this time, the two sliders 7 move backward, causing the tail fin 1 to retract into the receiving groove 4. The scissor assembly 3 has the advantages of structural stability, accurate motion trajectory and simple structure, and is suitable for driving the tail fin 1.

[0037] like Figures 2 to 4 As shown, both ends of the first rod 13 and both ends of the second rod 14 are provided with through holes. Both the positive thread slider 11 and the negative thread slider 12 are provided with first protrusions 15, the top surface of which is provided with a shaft 17 that matches the through hole. Both sliders 7 are provided with second protrusions 16, the top surface of which is provided with a shaft 17 that matches the through hole. In actual installation, the through hole at the front end of the first rod 13 mates with the shaft 17 of one slider 7, and the through hole at the front end of the second rod 14 mates with the shaft 17 of the other slider 7. The first rod 13 and the second rod 14 are arranged intersectingly. The through hole at the rear end of the first rod 13 mates with the shaft 17 on the negative thread slider 12, and the through hole at the rear end of the second rod 14 mates with the shaft 17 on the positive thread slider 11.

[0038] like Figure 2As shown, the base 8 includes a horizontal section 18 and two vertical sections 19 symmetrically arranged on both sides of the horizontal section 18. Each vertical section 19 contains a guide assembly for limiting the sliding of the tail fin 1 in the horizontal direction. The top surface of the horizontal section 18 has a first groove 24, and the top surface of the vertical section 19 has a second groove 25. The forward and reverse lead screws 9 and the motor are located in the first groove 24, and the guide assembly is located in the second groove 25. The bottom surface of the tail fin 1 has a third groove 26, and some of the cross links are located in the third groove 26. By providing the first groove 24, the second groove 25, and the third groove 26, the overall footprint of the telescopic structure is further reduced.

[0039] like Figure 3 As shown, the guide assembly includes a bracket 20, a guide rod 22 mounted on the bracket 20, and guide blocks 23 slidably mounted on the guide rod 22. Both ends of the mounting rod 6 are connected to the two guide blocks 23 respectively. By setting up the guide assembly, the accuracy of the scissor lift assembly 3 driving the tail fin 1 is further improved.

[0040] 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.
