[0002] The electric three-section rear wing is a car rear wing that can be automatically raised and deployed. The electric rear wing of a car, also known as the electric spoiler of a car, is an automotive component that affects the overall airflow of the car during high-speed driving. According to the principles of aerodynamics, the rear wing mainly provides a longitudinal downward pressure on the overall airflow of the car, thereby improving the stability of the car body and enhancing the grip during driving, indirectly reducing the energy consumption of the car, and at the same time adding a significant feature to the appearance of the car's rear, which plays a certain decorative role in the overall beauty of the car.

[0003] The electric three-stage tail wing is mainly divided into two movement actions: lifting and unfolding. The three-stage tail wing commonly seen on the market basically realizes lifting and unfolding movements with two sets of connecting rod mechanisms, which are driven by two motors to realize the movement. This patent retains the characteristics of the lifting movement mechanism and provides a new movement mechanism for the unfolding movement to realize the movement.

[0045] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0046] Example 1

[0047] This embodiment relates to a three-section tail wing opening and closing mechanism, used to deploy two side tail wings 2 on either side of a center tail wing 3 or to assemble them together. The opening and closing mechanism includes a drive unit 4 mounted on the vehicle body 1, a mounting portion 5 located at the power output end of the drive unit 4, and a guide portion mounted on the vehicle body 1. The mounting portion 5 is provided in a one-to-one correspondence with each side tail wing 2 and is used to mount the side tail wing 2.

[0048] Under the guidance of the guide part, the driving part 4 can drive the mounting part 5 to slide along the first path and the second path in sequence to unfold the two side tail wings 2, or slide along the second path and the first path in sequence to splice the two side tail wings 2 together, wherein the first path is a straight line and the second path is a downward inclined line.

[0049] The three-stage tail flap opening and closing mechanism of this embodiment provides a first path and a second path, allowing the two side tail flaps 2 to slide along the first and second paths, thereby achieving both the expanded and closed states of the two side flaps. This simple structure facilitates manufacturing and improves the installation efficiency of the opening and closing mechanism. The first and second paths are configured as a straight line and a downwardly inclined slot, respectively, to ensure smooth opening and closing of the side flaps.

[0050] Based on the above overall description, an exemplary structure of the opening and closing mechanism of the three-section tail wing of this embodiment is as follows: Figure 1 and Figure 2 As shown, the driving part 4 is provided on the vehicle body 1 and is located below the middle tail wing 3 , and the driving part 4 can drive the mounting parts 5 located below the two side tail wings to slide along the guide parts respectively, thereby realizing the expansion and closure of the two side tail wings 2 .

[0051] In this embodiment, as a preferred implementation, the guide portion includes a first slide rail 6 provided on the vehicle body 1, the first slide rail 6 having a straight slide groove 601 and an inclined slide groove 602 connected in sequence, the straight slide groove 601 forming a first path, and the inclined slide groove 602 forming a second path.

[0052] Specifically, refer to Figures 3 to 5 As shown in the figure, relatively open first slide rails 6 are respectively formed on the front and rear side walls of the vehicle body 1. The horizontal portion of the first slide rail 6 close to the middle tail wing 3 is a horizontal straight slide groove 601. An oblique slide groove 602 is connected to the end of the straight slide groove 601 away from the middle tail wing 3. The side tail wing 2 opens and closes by sliding along the straight slide groove 601 and the oblique slide groove 602.

[0053] In order to enable the side tail 2 to slide in the first slide rail 6, in this embodiment, corresponding to the aforementioned straight slide groove 601 and inclined slide groove 602, the above-mentioned mounting portion 5 has a plurality of rotatably arranged pulleys 504, the first slide rail 6 is arranged one-to-one corresponding to the pulleys 504, and the pulleys 504 are slidably arranged on the first slide rail 6.

[0054] like Figure 7 and Figure 10 As shown, corresponding to the shape of the slide groove, a pulley 504 is respectively connected to the front and rear sides of the side tail 2, and each pulley 504 is inserted into the slide groove and can slide along the slide groove. When the pulley 504 slides in the slide groove, it can drive the side tail 2 as a whole to slide along the vehicle body 1, thereby realizing the opening and closing process of the side tail 2.

[0055] Furthermore, in this embodiment, in order to drive the pulley 504 to slide along the slide groove, as a preferred embodiment, the power output end of the driving unit 4 is provided with a driving block 402 for driving the mounting unit 5 to slide, and the driving block 402 is provided with a slide groove. Furthermore, the mounting unit 5 further includes a mounting plate 501 having pins 502, which are inserted into slots 4021 and are capable of sliding within the slots 4021 along a third path, which is arranged orthogonally to the first path.

[0056] Reference Figures 2 to 5 and Figure 7 as well as Figure 10 As shown in FIG, a mounting plate 501 is provided at the bottom of the side fin 2, extending along the length of the side fin 2. A pulley 504 is provided on each of the front and rear sides of the mounting plate 501 in the width direction. A through hole 5011 is provided on the upper surface of the mounting plate 501, near the drive unit 4. The shape of the through hole 5011 conforms to the shape of the drive block 402, allowing the drive block 402 to be inserted into the through hole 5011.

[0057] And, as Figure 8 and Figures 11 to 12As shown in FIG, a slot 4021 is provided on the driving block 402 along its height direction, forming a third path. A pin 502 is provided on the mounting plate 501 at a position corresponding to the slot 4021. The pin 502 can be inserted into the slot 4021 and can slide within the slot 4021.

[0058] In order to improve the connection effect between the slot 4021 and the pin 502. In this embodiment, as a preferred embodiment, Figure 7 As shown, the pin 502 is coated with a colloid 503, and the pin 502 abuts against the wall of the slot 4021 through the colloid 503. The colloid 503 coating the pin 502 helps reduce wear caused by sliding between the pin and the slot 4021. The colloid 503 coating the pin 502 also reduces the tolerance between the pin 502 and the slot 4021, which helps improve the connection between the pin and the slot.

[0059] To improve the control efficiency of the two side spoilers 2, in this embodiment, the two mounting portions 5 are connected to the same drive unit 4. Specifically, as a preferred embodiment, the drive unit 4 includes a motor 401, with a gear 403 mounted on its output shaft. Rack shafts 404 mesh with each other on either side of the gear 403. A drive block 402 is mounted on the rack shaft 404. A second slide rail 7 is provided on the vehicle body 1, and the drive block 402 slides on the second slide rail 7.

[0060] Reference Figure 6 As shown in the figure, the two mounting plates 501 are respectively arranged on both sides of the motor 401, and a gear 403 is provided downwardly at the output end of the motor 401, and the front and rear sides of the gear 403 are respectively engaged with rack shafts 404, and the other end of the rack shaft 404 is connected to the aforementioned driving block 402. When the motor 401 drives the gear 403 to rotate, the engagement of the gear 403 with the two rack shafts 404 can make the two rack shafts 404 move toward or away from each other. At the same time, the driving block 402 provided at the other end of the rack shaft 404 can drive the tail wing 2 on both sides to move.

[0061] In order to improve the sliding connection effect between the driving block 402 and the rack shaft 404, in this embodiment, referring to Figure 11 and Figure 12 As shown, the bottom of the driving block 402 is set to be arc-shaped, so that the contact between the driving block 402 and the second slide rail 7 is line contact, which can effectively reduce the friction between the two, thereby improving the sliding efficiency between the driving block 402 and the second slide rail 7.

[0062] Moreover, the driving block 402 is arranged on the rack shaft 404 by rubber coating. By adding the elastic structure between the driving block 402 and the second slide rail 7, the gap between the driving block 402 and the second slide rail 7 can be reduced, so that the cooperation effect between the two is better, and the sliding friction between the driving block 402 and the second slide rail 7 can be reduced to improve the sliding efficiency of the driving block 402.

[0063] In addition, in this embodiment, in order to ensure the accuracy of the sliding direction of the rack shaft 404, as a preferred embodiment, Figures 4 and 5 and Figure 7 As shown, a limiting plate 8 is provided on the vehicle body 1 near the second slide rail 7. A track is formed on the limiting plate 8 for the rack shaft 404 to slide. The track guides the movement of the rack shaft 404 and limits the movement of the rack shaft 404 in other directions, thereby improving the mechanical transmission efficiency. Of course, in this embodiment, the limiting plate 8 can also be configured as other structures with guiding and limiting effects, and this is not specifically limited here.

[0064] In this embodiment, when driving the two side tail wings 2 to unfold relative to the middle tail wing 3, the motor 401 is started, and the motor 401 drives the gear 403 to rotate through the output shaft of the motor 401. The rack shaft 404 is engaged with the gear 403, so that the two rack shafts 404 start to move in opposite directions as the gear 403 rotates, and the driving block 402 connected to the end of the rack shaft 404 moves along the second slide rail 7.

[0065] At the same time, the groove wall of the slide groove on the driving block 402 can push the pin 502 and the mounting plate 501 to slide along the first slide rail 6 until the pulleys 504 provided on both sides of the mounting plate 501 slide from one end of the straight slide groove 601 to the other end, and the mounting plate 501 moves down to the bottom end along the inclined slide groove 602 with the pulley 504, and the pin 502 on the mounting plate 501 can also move downward along the slot 4021 on the driving block 402 until the side tail 2 is fully deployed.

[0066] When the two side tail wings 2 are in the closing process, the driving motor 401 rotates in the reverse direction, and the relative sliding between other components then moves in the reverse direction relative to the unfolding process, thereby achieving the closing between the two side tail wings 2.

[0067] Example 2

[0068] This embodiment relates to a vehicle provided with the opening and closing mechanism of the three-section tail wing in the first embodiment.

[0069] The vehicle of this embodiment, by providing the opening and closing mechanism of the three-stage rear wing of the first embodiment, can reduce the complex connecting rod structure and the assembly of parts, thereby reducing production costs. At the same time, it can also reduce the problem of excessive assembly errors caused by too many parts, which affects the overall operation, thereby improving the user experience of the vehicle.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
