Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle rear wing technology, and more particularly to a rear wing structure and vehicle. Background Technology
[0002] A rear wing is an aerodynamic component installed at the rear of a vehicle. It mainly generates a downward force by changing the direction of the airflow passing through the rear of the vehicle and creating a pressure difference between the upper and lower surfaces of the wing. This increases the downforce of the vehicle at high speeds, thereby improving the downforce and stability of the vehicle at high speeds.
[0003] In related technologies, a tail wing typically consists of three parts: the wing body, the support base, and the adjustment mechanism. The wing body employs an aerodynamic design, the support base is rigidly connected to the vehicle's sheet metal structure, and the adjustment mechanism is used to adjust the tail wing's angle of attack. Because the tail wing needs to withstand significant aerodynamic loads at high speeds, the support base requires a large contact area, necessitating the creation of large through-holes in the vehicle's sheet metal to mount the support base.
[0004] However, if the size of the through hole is too large, it will weaken the overall rigidity of the body structure, leading to increased vibration of the sheet metal parts and affecting the stability of the entire body structure. Utility Model Content
[0005] This application provides a rear wing structure and vehicle to solve the problem that excessively large through holes weaken the overall rigidity of the vehicle body structure, leading to increased vibration of sheet metal parts and affecting the stability of the entire vehicle body structure.

[0022] In one possible implementation, the transmission mechanism further includes a first buffer member disposed on the lower support. When the tail fin body is in the retracted position, the upper support and the first buffer member abut against each other.
[0023] In one possible implementation, the transmission mechanism further includes a second buffer member disposed on the lower support. When the tail fin body is in the deployed position, the end of the fourth link connected to the lower support abuts against the second buffer member.
[0024] In one possible implementation, a connector is also included, which is connected to the tail fin body and the upper support respectively.
[0025] In one possible implementation, the connector includes:
[0026] The support portion has two mounting holes, and the mounting holes are provided with internal threads.
[0027] A first insertion part is provided on the support part, and the first insertion part is inserted into the tail wing body;

[0055] Unless otherwise stated, the term "multiple" means two or more.
[0056] As described in the background section, a rear wing is an aerodynamic component installed at the rear of a vehicle. It mainly generates a downward force by changing the direction of the airflow passing through the rear of the vehicle and creating a pressure difference on the upper and lower surfaces of the wing. This increases the downforce of the vehicle at high speeds, thereby improving the downforce and stability of the vehicle at high speeds.
[0057] In related technologies, a tail wing typically consists of three parts: the wing body, the support base, and the adjustment mechanism. The wing body employs an aerodynamic design, the support base is rigidly connected to the vehicle's sheet metal structure, and the adjustment mechanism is used to adjust the tail wing's angle of attack. Because the tail wing needs to withstand significant aerodynamic loads at high speeds, the support base requires a large contact area, necessitating the creation of large through-holes in the vehicle's sheet metal to mount the support base.
[0058] However, if the size of the through hole is too large, it will weaken the overall rigidity of the body structure, leading to increased vibration of the sheet metal parts and affecting the stability of the entire body structure.
[0059] The rear wing structure and vehicle provided in this application include a cover, which comprises a tailgate and a rear section, with two through holes on the rear section; a base located between the rear section and the vehicle body; two transmission mechanisms mounted on the base and respectively passing through the two through holes; and a rear wing body connected to the transmission mechanisms, which are configured to drive the rear wing body to move between a retracted position and an deployed position. In the retracted position, the rear wing body covers the rear section; in the deployed position, the rear wing body rises to guide airflow. Thus, by using the cover, the tailgate and rear section are integrated into a single structure, directly covering the vehicle body, eliminating the need for openings in the vehicle body and ensuring the overall strength and stability of the vehicle.
[0060] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0062] Please refer to Figures 1 to 6 In a first aspect, this embodiment provides a tail wing structure, including a cover 100, which includes a tailgate portion 110 and a rear portion 120, with two through holes 1201 on the rear portion 120; a base 200 located between the rear portion 120 and the vehicle body; two transmission mechanisms 300 disposed on the base 200 and respectively passing through the two through holes 1201; and a tail wing body 400 connected to the transmission mechanisms 300, wherein the transmission mechanisms 300 are configured to drive the tail wing body 400 to move between a retracted position and an extended position. When in the retracted position, the tail wing body 400 covers the rear portion 120, and when in the extended position, the tail wing body 400 is raised to guide airflow.
[0063] Specifically, in this embodiment, the cover 100 is an integral structure, including the tailgate 110 and the rear of the vehicle 120, so that the entire cover 100 forms a continuous force-bearing whole, avoiding the problem of needing to open a large through hole 1201 on the vehicle sheet metal when installing the rear wing structure in traditional vehicles, thus maintaining the integrity and sealing of the vehicle body.
[0064] In this embodiment, the rear end 120 of the cover 100 has two through holes 1201 for mounting the transmission mechanism 300. Specifically, when the transmission mechanism 300 drives the tail wing body 400 to move between the retracted position and the deployed position, the transmission mechanism 300 extends into or out of the through holes 1201, thereby realizing the lifting and lowering movement of the tail wing body 400.
[0065] When the rear wing body 400 is in the retracted position, the transmission mechanism 300 is located within the through hole 1201. At this time, the rear wing body 400 is completely fitted to the outer surface of the rear of the vehicle 120, forming a continuous body contour and ensuring the vehicle's aesthetics. When the rear wing body 400 is in the deployed position, the transmission mechanism 300 extends out of the through hole 1201. At this time, the rear wing body 400 is raised to a predetermined height, forming a specific airflow guiding surface, thereby guiding the airflow to generate downforce and ensuring the stability of the vehicle at high speeds.
[0066] It should also be noted that in this embodiment, there are two transmission mechanisms 300. The two transmission mechanisms 300 are respectively set on both ends of the bottom surface of the tail wing body 400, thereby providing dual-point support for the tail wing body 400, ensuring the balance and stability of the tail wing body 400 during movement, and effectively preventing the torsion or deflection problems that may occur with single-point drive.
[0067] The spacing between the two transmission mechanisms 300 can be adapted to the length of the tail wing body 400 and the length of the vehicle's rear end; however, this embodiment does not impose any restrictions on this.
[0068] In an optional embodiment, the transmission mechanism 300 includes an upper support 310, on which the tail wing body 400 is disposed; a first drive member 320, on which the base 200 is disposed; and a linkage assembly 330, on which the base is disposed, with the tail wing body disposed on the linkage assembly 330. The first drive member is configured to drive the linkage assembly 330 to move so as to move the tail wing body between a retracted position and an extended position.
[0069] Specifically, in this embodiment, the linkage assembly 330 uses a combination of multiple linkages to achieve the lifting and lowering movement of the tail wing body 400.
[0070] Specifically, in this embodiment, the upper bracket 310 serves as the mounting platform for the tail wing body 400 and is directly connected to the tail wing body 400 to support the tail wing body 400 and ensure the stability of the tail wing body 400 during lifting and lowering.
[0071] This embodiment employs a linkage mechanism to drive the tail fin body 400 up and down, enabling more precise control over its movement trajectory and ensuring that the tail fin body 400 moves strictly according to the preset position, avoiding deviations. Simultaneously, the combination of multiple linkages allows the tail fin body 400 to form a stable support structure in the deployed position, thereby significantly improving its resistance to airflow impact.
[0072] Please refer to Figures 1 to 6 In an optional embodiment, the linkage assembly 330 includes: a first linkage connected to the output end of the first drive member; a second linkage rotatably connected to the end of the first linkage not connected to the first drive member; a third linkage rotatably connected at one end to the upper support, and the end of the second linkage not connected to the first linkage rotatably connected to the third linkage; and a fourth linkage rotatably connected to the base and at the other end to the upper support. The first drive member is configured to drive the first linkage to rotate, thereby moving the tail fin body between a retracted position and a deployed position.
[0073] Specifically, during actual operation, the first driving component 320 drives the first connecting rod 331 to rotate in a circular motion. The first connecting rod 331, acting as the active rod, converts the rotational motion into planar motion. At this time, the end of the first connecting rod 331 connected to the second connecting rod 332 pulls the second connecting rod 332, which in turn drives the third connecting rod 333 to move. The third connecting rod 333 then converts the motion into a lifting motion of the upper support 310. Simultaneously, the fourth connecting rod 334, acting as a fixed-length constraint rod, is rotatably connected at one end to the base 200 and at the other end to the upper support 310, ensuring that the upper support 310 can move along a preset trajectory.
[0074] Specifically, in this embodiment, the second link 332, when pulled by the first link 331, has two extreme positions: folded relative to the first link 331 and unfolded relative to the first link 331. When the first link 331 and the second link 332 are folded relative to each other, the end of the second link 332 connected to the third link 333 is at its lowest height, causing the upper support 310 to descend to its extreme position, at which point the tail fin body 400 is in a retracted state. When the first link 331 and the second link 332 are unfolded relative to each other, the end of the second link 332 connected to the third link 333 is at its highest height, causing the upper support 310 to rise to its extreme position, at which point the tail fin body 400 is in an unfolded state. The first drive member 320 drives the first link 331 to perform a circular motion to switch between the two extreme positions of folded relative to the second link 332 and unfolded relative to the second link 332, thereby realizing the raising and lowering of the tail fin body 400.
[0075] Please refer to Figures 1 to 6 In an optional embodiment, the transmission mechanism 300 further includes a lower support 340, which is disposed on the base 200. The first driving member 320 is disposed on the lower support 340, and the end of the fourth link 334 that is not connected to the upper support 310 is rotatably connected to the lower support 340.
[0076] Specifically, in this embodiment, the lower bracket 340 is fixedly mounted on the base 200, serving as the mounting support for the entire transmission mechanism 300. The first driving member 320 is disposed on the lower bracket 340, thereby avoiding interference between the first driving member 320 and each connecting rod, which would affect the normal operation of the connecting rod.
[0077] Meanwhile, in this embodiment, one end of the fourth link 334 is connected to the upper bracket 310, and the other end is rotatably connected to the lower bracket 340, forming a stable support structure. The first driving member 320 transmits the driving force to the first link 331 through the lower bracket 340, while the fourth link 334 transmits the reaction force to the base 200 through the lower bracket 340, thereby optimizing the force flow path.
[0078] Furthermore, in this embodiment, the lower bracket 340 is bolted to the base 200, so that when the transmission mechanism 300 needs to be repaired or maintained, the lower bracket 340 can be removed from the base 200, allowing the operator to directly access the entire transmission mechanism 300 without disassembling the entire base 200, which greatly improves the convenience of operation.
[0079] Please refer to Figures 1 to 6 In an optional embodiment, the transmission mechanism 300 further includes a limiting member 350 disposed on the lower support 340, wherein when the tail fin body 400 is in the deployed position, the first link 331 approaches the limiting member 350.
[0080] Specifically, during the operation of the rear wing structure, if the transmission mechanism 300 malfunctions, the rear wing body 400 may over-deploy. When the rear wing body 400 over-deploys, it disrupts the aerodynamic balance of the entire vehicle, causing the vehicle to experience downforce exceeding preset values. This leads to an abnormal increase in load on the rear axle, affecting the vehicle's handling stability. Simultaneously, the abnormally deployed rear wing body 400 alters the vehicle's drag coefficient, increasing fuel consumption and potentially generating high-frequency vibrations due to airflow disturbances, thus seriously endangering driving safety.
[0081] To avoid the above problems, the transmission mechanism 300 provided in this embodiment includes a limiting member 350. When the tail wing body 400 is in the deployed position, the first link 331 does not contact the limiting member 350. However, if the tail wing body 400 continues to deploy beyond the preset deployment position, the first link 331 abuts against the limiting member 350, thereby limiting the rotation of the first link 331 and preventing the tail wing body 400 from being over-deployed.
[0082] The distance between the limiting member 350 and the first connecting rod 331 can be adjusted adaptively according to actual needs, and this embodiment does not impose any restrictions on this.
[0083] In an optional embodiment, the transmission mechanism 300 further includes a first buffer 360, which is disposed on the lower support 340. When the tail fin body 400 is in the retracted position, the upper support 310 and the first buffer 360 abut against each other.
[0084] Specifically, in this embodiment, the first buffer 360 is made of elastic material and is mounted on the lower support 340. When the first drive member 320 drives the first connecting rod 331 to rotate and cause the tail fin body 400 to gradually retract, the upper support 310 will abut against the first buffer 360. Thus, the first buffer 360 can absorb the remaining kinetic energy of the upper support 310 through elastic deformation, so that the tail fin body 400 can come to a smooth stop.
[0085] The first buffer 360 can be made of rubber, silicone or polyurethane elastomer, etc. This embodiment does not impose any restrictions on this, and the operator can make an appropriate choice according to actual needs.
[0086] In an optional embodiment, the transmission mechanism 300 further includes a second buffer 370, which is disposed on the lower support 340. When the tail fin body 400 is in the deployed position, the end of the fourth link 334 connected to the lower support 340 abuts against the second buffer 370.
[0087] Specifically, in this embodiment, the second buffer 370 is made of elastic material and is mounted on the lower support 340. When the first drive member 320 drives the first connecting rod 331 to rotate and cause the tail fin body 400 to gradually unfold, the fourth connecting rod 334 will abut against the second buffer 370. Thus, the second buffer 370 can absorb the remaining kinetic energy of the fourth connecting rod 334 through elastic deformation, so that the tail fin body 400 can come to a smooth stop.
[0088] The second buffer 370 can be made of rubber, silicone or polyurethane elastomer, etc. This embodiment does not impose any restrictions on this, and the operator can make an appropriate choice according to actual needs.
[0089] In an optional embodiment, the tail fin structure further includes a connector 500, which is connected to the tail fin body 400 and the upper support 310, respectively.
[0090] Specifically, in this embodiment, the tail wing structure is connected to the tail wing body 400 and the upper support 310 by the connector 500 to ensure the stability of the tail wing body 400 and the structural stability under the impact of high-speed airflow.
[0091] Optionally, the connector 500 can be a bolted structure, facilitating quick assembly, disassembly, and maintenance. The bolts can incorporate an anti-loosening design to ensure stable connection strength even under severe vibration conditions.
[0092] In other embodiments, the specific structure and number of connectors 500 can also be adapted, and this embodiment does not impose any restrictions on this.
[0093] In an optional embodiment, the connector 500 includes a support portion 510 with two mounting holes 511 and internal threads in the mounting holes 511; a first insertion portion 520 disposed on the support portion 510 and inserted into the tail fin body 400; a second insertion portion 530 disposed on the support portion 510 and located on two opposite surfaces of the support portion 510, and inserted into the upper bracket 310; and two locking members 540 with external threads that match the internal threads. The locking members 540 pass through the tail fin body 400, the mounting holes 511, and the upper bracket 310 in sequence to connect the tail fin body 400 and the upper bracket 310.
[0094] Specifically, in this embodiment, the first insertion part 520 and the second insertion part 530 are located on the upper surface and lower surface of the support part 510, respectively. The first insertion part 520 is inserted into the preset cavity of the tail wing body 400, and the second insertion part 530 is inserted into the corresponding mounting position on the upper bracket 310, thereby realizing the positioning of the tail wing body 400, the support part 510 and the upper bracket 310, which facilitates further installation.
[0095] The mounting hole 511 on the support part 510 is provided with an internal thread, which cooperates with the external thread of the locking member 540. When the locking member 540 passes through the tail fin body 400, the mounting hole 511 and the upper bracket 310 in sequence and is tightened, the tail fin body 400, the support part 510 and the upper bracket 310 are rigidly locked, ensuring the stability of the connection between the tail fin body 400 and the upper bracket 310. This ensures the structural stability of the tail fin body 400 under the impact of high-speed airflow and facilitates quick disassembly and assembly during daily maintenance.
[0096] In this embodiment, there are two locking members 540, which are symmetrically arranged on the support part 510, thereby achieving dual-point fixation, evenly distributing the connection load, and ensuring the reliability of the connection.
[0097] Furthermore, it should be noted that due to manufacturing tolerances, after the rear wing body 400 and the upper bracket 310 are connected, there may be a problem where the rear wing body 400 cannot completely fit against the rear of the vehicle 120. Therefore, the installation position of the rear wing body 400 can be adjusted by adjusting the screwing depth of the locking member 540.
[0098] Specifically, when a gap is found between the rear wing body 400 and the rear of the vehicle 120, the screwing depth of the locking part 540 can be gradually adjusted. By utilizing the precision adjustment characteristics of the threaded drive, the rear wing body 400 can produce a slight displacement change, thereby adjusting the installation height and tilt angle of the rear wing body 400 to ensure that the rear wing body 400 can fit against the surface of the rear of the vehicle 120.
[0099] In an optional embodiment, the base 200 has two reinforcing parts 210, and two transmission mechanisms 300 are respectively disposed on the two reinforcing parts 210.
[0100] Specifically, in this embodiment, the base 200 is provided with two reinforcing parts 210. The reinforcing parts 210 can be made of thickened material, so that the thickness of the reinforcing parts 210 is greater than the thickness of the base 200, thereby improving the local rigidity. The transmission mechanism 300 is respectively installed on the two reinforcing parts 210, thereby providing a stable support foundation for the transmission mechanism 300. This allows the dynamic load generated by the transmission mechanism 300 during operation to be transmitted and distributed through the reinforcing parts 210, ensuring the stability and accuracy of the tail fin body 400 during lifting and lowering.
[0101] The junction between the reinforcing part 210 and the base 200 can form a transition structure, so that the dynamic load generated when the transmission mechanism 300 is working can be evenly distributed to the main body of the base 200 through the reinforcing part 210, thus avoiding stress concentration.
[0102] Secondly, this embodiment provides a vehicle, including a vehicle body and a tail wing structure as described in the first aspect, wherein the tail wing structure is disposed on the vehicle body.
[0103] The specific structure of the tail fin has been described in the above embodiments and will not be repeated here.
[0104] The vehicle provided in this embodiment includes a vehicle body and a rear wing structure according to any one of the first aspects, wherein the rear wing structure is disposed on the vehicle body. The rear wing structure includes a cover 100, which includes a tailgate portion 110 and a rear portion 120, with two through holes 1201 on the rear portion 120; a base 200 located between the rear portion 120 and the vehicle body; two transmission mechanisms 300 disposed on the base 200 and respectively passing through the two through holes 1201; and a rear wing body 400 connected to the transmission mechanisms 300, wherein the transmission mechanisms 300 are configured to drive the rear wing body 400 to move between a retracted position and an deployed position. When in the retracted position, the rear wing body 400 covers the rear portion 120; when in the deployed position, the rear wing body 400 is raised to guide airflow. Thus, by setting the cover 100, the tailgate 110 and the rear of the vehicle 120 are integrated into a single structure, which is directly covered on the vehicle body, thereby eliminating the need to make openings in the vehicle body and ensuring the overall strength of the vehicle body and the stability of the entire vehicle.
