Description

Technical Field

[0001] This utility model relates to the field of automotive rear wing technology, and in particular to an intelligent rear wing adjustment device for new energy vehicles. Background Technology

[0002] The rear wing is an important component of a car's aerodynamic system. A specially designed rear wing shape can generate downforce at the rear of the car when it is traveling at high speeds, thereby counteracting the lift generated by the car body, ensuring that the tires have sufficient traction with the ground, thus improving the car's stability and handling, and also making more efficient use of power.

[0003] Currently, car rear wings are mainly divided into two categories: fixed rear wings and electric rear wings. Fixed rear wings cannot be adjusted in angle during driving, resulting in poor flexibility. In contrast, electric rear wings have more advantages. They can automatically deploy according to actual needs or vehicle speed and can be stored inside the vehicle body. This avoids the abruptness of traditional fixed rear wings while maintaining a sporty feel and smooth body lines. However, in order to better accommodate the rear spoiler and ensure smooth body lines, existing electric rear wings are mostly designed as straight plates. But at high speeds, wingtip vortices are easily formed at the ends of the rear wings. This not only reduces downforce efficiency but may also generate lateral instability. Therefore, this application provides an intelligent rear wing adjustment device for new energy vehicles to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an intelligent rear wing adjustment device for new energy vehicles. By setting secondary wings on both sides of the main wing, and forming side wings at both ends as the main wing opens, the secondary wings can enhance the lateral stability of the vehicle body when the vehicle is traveling at high speed, effectively reduce the impact of crosswinds on the vehicle, and maintain the balance of lateral wind resistance while increasing the downforce of the vehicle. The above settings can solve the problem that the straight rear wing generates vortices at the wingtip when the vehicle is traveling at high speed, which leads to the lateral instability of the vehicle.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A smart rear wing adjustment device for new energy vehicles includes a mounting base plate with two symmetrically arranged mounting slots inside. A main wing is arranged on the top of the mounting base plate, and auxiliary wing is symmetrically rotatably connected to both ends of the main wing. A lifting assembly is used to drive the main wing to rise and fall, and also to drive the auxiliary wing on both sides of the main wing to open and close. The lifting assembly is connected to the main wing and the auxiliary wing. A drive assembly is arranged at the bottom of the mounting base plate, and the drive assembly is used to drive the lifting assembly to move. The drive assembly is connected to the mounting base plate and the lifting assembly.

[0007] Optionally, the lifting assembly includes a mounting base installed inside the mounting slot, a drive arm rotatably connected to one side of the mounting base, a connecting arm rotatably connected to one end of the drive arm, a mounting platform rotatably connected to the top of the connecting arm, and two support arms rotatably connected between the mounting platform and the mounting base.

[0008] Optionally, the lifting assembly further includes symmetrically formed receiving slots inside the mounting base plate, a follower frame is rotatably connected inside the receiving slot, a constraint slot is formed inside the follower frame, a connecting rod is rotatably connected inside the constraint slot, and the end of the connecting rod away from the follower frame is rotatably connected to the aileron.

[0009] Optionally, the receiving groove has a "T" shaped structure, and the follower frame abuts against the inner wall of the receiving groove after rotation.

[0010] Optionally, the constraint groove is a semi-open structure, and one side of the connecting rod abuts against the inner wall of the constraint groove.

[0011] Optionally, the main wing has symmetrical slots inside, and the aileron is fixedly connected to an elastic element on the side near the main wing, with the elastic element inserted into the slot.

[0012] Optionally, the drive assembly includes a drive motor fixed to the bottom of the mounting base plate, a drive gear fixedly connected to the output end of the drive motor, a transmission shaft rotatably connected between the two mounting slots, a driven gear fixedly connected to the outside of the transmission shaft, and the driven gear meshing with the drive gear.

[0013] Optionally, both ends of the drive shaft pass through the mounting base and are fixedly connected to the drive arm.

[0014] Optionally, a microcontroller is fixedly connected to the bottom of the mounting base plate, and the drive motor is electrically connected to the microcontroller.

[0015] Optionally, the bottom of the main wing is provided with multiple air guide ribs at equal intervals.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above-mentioned solution, the intelligent rear wing adjustment device for new energy vehicles provided in this application is equipped with a drive component and a lifting component working together on the mounting base plate. When the main wing is raised, the aileron can be opened simultaneously. When the vehicle is traveling at high speed, the aileron can enhance the lateral stability of the vehicle body, effectively reduce the impact of crosswinds on the vehicle, increase the downforce of the vehicle, maintain the balance of lateral wind resistance, and thus improve the stability of the vehicle.

[0018] The follower frame and linkage can move in tandem with the lifting and lowering of the main wing, ensuring the smooth opening and closing of the ailerons without the need for additional external drive equipment.

[0019] By setting interlocking slots and elastic elements on the main wing and aileron, appropriate resistance can be provided for the opening of the aileron. In this way, the follower frame can be ensured to rotate before the connecting rod, and the aileron can be ensured to rotate after it separates from the vehicle body with the main wing, effectively avoiding the aileron from rubbing against the vehicle body when it opens.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, this embodiment of the present invention provides an intelligent rear wing adjustment device for new energy vehicles, including a mounting base plate 1. The mounting base plate 1 has two symmetrically arranged mounting slots 101 inside. The mounting slots 101 provide space for the installation of the lifting assembly 2, ensuring the compactness of the main wing 3 when closed and reducing the space occupied by the vehicle body. A main wing 3 is arranged above the mounting base plate 1, and auxiliary wings 301 are symmetrically rotatably connected to both ends of the main wing 3. The auxiliary wings 301 can move with the main wing 3 when it rises, without requiring external power, reducing equipment costs while ensuring the effect of mechanical linkage. The main wing 3 has symmetrically opened slots 302 inside, and a spring is fixedly connected to the side of the auxiliary wing 301 near the main wing 3. The elastic element 303 is inserted into the slot 302, providing appropriate resistance for the opening of the aileron 301 and providing buffering when the aileron 301 closes to avoid rigid collisions. Multiple air guide ribs are equidistantly arranged at the bottom of the main wing 3, which further optimize the airflow path and enhance downforce. The lifting assembly 2 is used to drive the main wing 3 to rise and fall, and also to drive the opening and closing of the ailerons 301 on both sides of the main wing 3. The lifting assembly 2 is connected to the main wing 3 and the ailerons 301. A drive assembly 4 is provided at the bottom of the mounting base plate 1, which drives the lifting assembly 2 to move. The drive assembly 4 is connected to the mounting base plate 1 and the lifting assembly 2.

[0036] In this embodiment, as Figures 2 to 5As shown, the lifting assembly 2 includes a mounting base 201 installed inside the mounting slot 101. A drive arm 202 is rotatably connected to one side of the mounting base 201, and a connecting arm 203 is rotatably connected to one end of the drive arm 202. A mounting platform 204 is rotatably connected to the top of the connecting arm 203. Two support arms 205 are rotatably connected between the mounting platform 204 and the mounting base 201. By rotating the drive arm 202 and the connecting arm 203, the main wing 3 can be lifted and lowered, realizing the opening and closing of the main wing 3. The two support arms 205 can play a role in stabilizing the structure and ensuring the smooth movement of the mounting platform 204 and the main wing 3. The lifting assembly 2 also includes symmetrically opened receiving slots 206 inside the mounting base plate 1. A follower frame 207 is rotatably connected inside the receiving slot 206. A constraint slot 208 is opened inside the follower frame 207. The constraint groove 208 is rotatably connected to a connecting rod 209, and the end of the connecting rod 209 away from the follower frame 207 is rotatably connected to the aileron 301. The receiving groove 206 has a "T" shaped structure. After the follower frame 207 rotates, it abuts against the inner wall of the receiving groove 206. The constraint groove 208 has a semi-open structure, and one side of the connecting rod 209 abuts against the inner wall of the constraint groove 208. By setting the receiving groove 206 with a T-shaped structure, not only can the follower frame 207 and the connecting rod 209 be stored, but the follower frame 207 after rotation can also abut against the inner wall of the receiving groove 206, which can constrain the rotation range of the receiving groove 206. The constraint groove 208 can limit the rotation angle of the connecting rod 209, thereby ensuring that it can pull the aileron 301, thereby driving the aileron 301 to rotate and open to form a side wing.

[0037] In this embodiment, as Figures 1 to 3 As shown, the drive assembly 4 includes a drive motor 401 fixed to the bottom of the mounting base 1. The output end of the drive motor 401 is fixedly connected to a drive gear 402. A transmission shaft 403 is rotatably connected between two mounting slots 101. A driven gear 404 is fixedly connected to the outside of the transmission shaft 403, and the driven gear 404 meshes with the drive gear 402. Both ends of the transmission shaft 403 pass through the mounting base 201 and are fixedly connected to the drive arm 202. A microcontroller 5 is fixedly connected to the bottom of the mounting base 1. The drive motor 401 is electrically connected to the microcontroller 5. When the drive motor 401 starts, it drives the drive gear 402 to rotate, and with the cooperation of the driven gear 404, it transmits power to the transmission shaft 403. The transmission shaft 403 drives the drive arm 202 to rotate, thereby driving the lifting assembly 2. The microcontroller 5 is connected to the vehicle computer and can control the start of the drive assembly 4 according to the real-time speed of the vehicle, ultimately achieving the opening of the main wing 3.

[0038] The working principle of this utility model:

[0039] The microcontroller 5 can determine the opening scheme of the rear wing based on parameters such as vehicle speed or driving mode. When the vehicle speed reaches the preset range for rear wing opening, the microcontroller 5 controls the drive motor 401 to start. At this time, the drive motor 401 drives the drive gear 402 to rotate, and in conjunction with the driven gear 404, transmits power to the transmission shaft 403. The transmission shaft 403 then drives the drive arm 202 to rotate. When the drive arm 202 rotates, it drives the connecting arm 203 to rotate, thereby lifting the mounting platform 204. At this time, the support arm 205 rotates with the lifting of the mounting platform 204, providing support for the mounting platform 204. When the mounting platform 204 is lifted, it drives the main wing 3 and the aileron 3. When the main wing 3 and the aileron 301 rise, the aileron 301 is connected by an interlocking groove 302 and an elastic element 303. Therefore, as the main wing 3 rises, the aileron 301 moves the connecting rod 209, which in turn rotates the follower frame 207. When the follower frame 207 rotates to contact the inner wall of the receiving groove 206, the connecting rod 209 begins to pull on the aileron 301. At this time, the aileron 301 rotates at one end of the main wing 3, forcing the elastic element 303 to disengage from the groove 302. During this process, the main wing 3 and the aileron 301 are separated from the vehicle, thus preventing the aileron 301 from scraping the vehicle during rotation. Figure 4 As shown, when the main wing 3 is fully raised, the ailerons 301 form side wings at both ends of the main wing 3, which can prevent the formation of wingtip vortices and improve the lateral stability of the vehicle. When the main wing 3 is retracted, the drive arm 202, connecting arm 203 and support arm 205 on its lifting assembly 2 rotate in opposite directions and are retracted into the mounting slot 101. During this process, the connecting rod 209 cooperates with the follower frame 207 to squeeze the ailerons 301, causing the ailerons 301 to rotate in the direction of the main wing 3. When the ailerons 301 contact the main wing 3, the elastic element 303 is inserted into the slot 302 again, while the follower frame 207 and connecting rod 209 are retracted into the receiving slot 206, and the entire tail wing is retracted into the vehicle.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
