[0001] The utility model relates to the technical field of vehicles, in particular to a tail wing assembly and a vehicle. Background Art

[0002] When the vehicle is driving, when the speed of the vehicle increases, the air generates buoyancy on the vehicle, which reduces the grip of the vehicle body, thereby reducing the friction of the vehicle body, which can easily lead to danger; when the speed of the vehicle slows down, the air generates less buoyancy on the vehicle, and the vehicle does not need too much grip. If the grip is too large, it will increase the friction between the vehicle and the ground and the wind resistance, and increase the energy consumption of the vehicle. In the related art, the rear wing is used to provide downforce to the vehicle to improve the grip of the vehicle, thereby improving safety. However, in the related art, the opening area of ​​the rear wing of the vehicle is fixed, which results in the vehicle's grip being fixed during driving, and it cannot be adaptively adjusted according to the actual vehicle speed, and cannot meet the user's driving needs under different vehicle conditions.

[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Reference below Figures 1-12 A tail assembly 100 according to an embodiment of the present invention is described.

[0041] The tail wing assembly 100 according to the first embodiment of the utility model includes: a first driving unit 10, a tail wing plate 30 and a pressure sensor.

[0042] refer to Figures 7-9 The first driving unit 10 includes a first mounting seat 11 and a first driving mechanism 12, and the first driving mechanism 12 is disposed on the first mounting seat 11. The tail wing plate 30 is located above the first driving unit 10 and includes a fixed wing plate 31 and a movable wing plate 32 that can move relative to each other. The first driving mechanism 12 is transmission-connected with the movable wing plate 32 to drive the movable wing plate 32 to move. By dividing the tail wing plate 30 into a fixed wing plate 31 and a movable wing plate 32, and the movable wing plate 32 can move relative to the fixed wing plate 31, the opening area of ​​the tail wing plate 30 can be changed. For example, the movable wing plate 32 can slide relative to the fixed wing plate 31. When the movable wing plate 32 slides in a direction away from the fixed wing plate 31, the opening area of ​​the tail wing plate 30 increases. When the opening area of ​​the tail wing plate 30 is the largest, the movable wing plate 32 is in the first position; when the movable wing plate 32 slides in a direction close to the fixed wing plate 31, the opening area of ​​the tail wing plate 30 decreases. When the opening area of ​​the tail wing plate 30 is the smallest, the movable wing plate 32 is in the second position. By connecting the first driving mechanism 12 to the moving wing plate 32 and driving the moving wing plate 32 to move, the opening area of ​​the tail wing plate 30 can be changed. The opening areas of the tail wing plate 30 are different, so that the tail wing plate 30 can provide different grips to meet the driving requirements under different wind resistance conditions.

[0043] The pressure sensor is disposed on the tail wing plate 30 and is used to detect the wind pressure at the tail wing plate 30. For example, the pressure sensor can be disposed on the movable wing plate 32 or the fixed wing plate 31. For example, the pressure sensor includes a probe and a sensor body. The probe is used to detect the magnitude of the pressure, and the sensor body is used to convert the pressure signal transmitted by the probe into an electrical signal and transmit it to other components. By providing a pressure sensor on the tail wing plate 30, the sensor can directly detect the pressure, and the detection result is more accurate.

[0044] Wherein, both the pressure sensor and the first driving mechanism 12 are adapted to be electrically connected to the control unit, and the control unit is used to control the first driving mechanism 12 according to the pressure signal of the pressure sensor.

[0045] For example, referring to Figure 2 and Figure 3 , when the vehicle is traveling at a relatively high speed, the pressure sensor senses that the wind pressure at the tail wing plate 30 is small, the downward pressure on the tail wing plate 30 is small, the vehicle is greatly affected by the upward buoyancy of the air, resulting in a decrease in the grip, and the friction between the vehicle and the ground decreases, which is prone to danger. Therefore, a larger grip is required. By driving the movable wing plate 32 to move by the first driving unit 10 to increase the opening area of the tail wing plate 30, the aerodynamic effect of the tail wing plate 30 can be enhanced, the vehicle can be subjected to a larger grip, the friction between the vehicle and the ground can be increased, and the stability of the vehicle during high-speed driving can be improved, ensuring the vehicle is safer.

[0046] For example, referring to Figure 4 and Figure 5 , when the vehicle is traveling at a relatively low speed, the pressure sensor senses that the wind pressure at the tail wing plate 30 is large, the downward pressure on the tail wing plate 30 is large, and the vehicle does not need to additionally increase a large grip to ensure safety. Therefore, a smaller grip is required to save energy. By driving the movable wing plate 32 to move by the first driving unit 10 to reduce the area of the tail wing plate 30, the effect of the tail wing plate 30 can be weakened, the vehicle can be subjected to a smaller grip, and the increase in the friction between the vehicle and the ground can be reduced, saving energy.

[0047] By electrically connecting both the pressure sensor and the first driving mechanism 12 to the control unit of the vehicle, and enabling the control unit to control the first driving mechanism 12 according to the pressure signal of the pressure sensor, the tail wing plate 30 can change the opening area of the tail wing plate 30 according to different signals received by the pressure sensor, so as to ensure that the tail wing plate 30 can provide different downward pressures under different vehicle conditions.

[0048] According to the tail wing assembly 100 of the embodiments of the present utility model, by setting the tail wing plate 30 into a fixed wing plate 31 and a movable wing plate 32 that can move relative to each other, and the movable wing plate 32 can be driven by the first driving mechanism 12 to move, the opening area of the tail wing plate 30 can be adjusted, so that the grip of the vehicle can be adjusted. By detecting the wind pressure at the tail wing plate 30 with a pressure sensor, the opening area of the tail wing can be increased when the vehicle speed is relatively high to provide sufficient grip, and at the same time, the opening area of the tail wing plate 30 can be reduced when the vehicle speed is relatively low to make the grip smaller and reduce energy consumption, enabling the vehicle to automatically adjust the opening area of the tail wing plate 30 according to the wind pressure at the tail wing plate 30 to meet the requirements for grip under different vehicle conditions; and, by arranging the pressure sensor on the tail wing plate 30, the accuracy of the detection result of the wind pressure at the tail wing plate 30 can be improved.

[0049] According to some embodiments of the present utility model, referring to Figure 6 , the pressure sensor is arranged on the movable wing plate 32. By arranging the pressure sensor on the movable wing plate 32, the pressure value detected by the pressure sensor can be made more accurate.

[0050] According to some embodiments of the present utility model, referring to Figure 6 , an avoidance hole 33 is provided on the movable wing plate 32, and the pressure sensor is placed in the avoidance hole 33. By providing the avoidance hole 33 on the movable wing plate 32 and arranging the pressure sensor in the avoidance hole 33, the pressure sensor can directly detect the wind pressure signal at the tail wing plate 30, making the signal received by the probe more accurate. And, by providing the avoidance hole 33 on the movable wing plate 32, it can prevent the probe of the sensor from interfering with the movable wing plate 32 and causing component damage.

[0051] According to some embodiments of the present utility model, referring to Figure 3 and Figure 5 , the movable wing plate 32 is slidable relative to the fixed wing plate 31. The movable wing plate 32 includes a movable wing main body 34 and a mating portion 35. The movable wing main body 34 and the mating portion 35 are arranged along the sliding direction of the movable wing plate 32. The mating portion 35 is in sliding fit with the fixed wing plate 31 and the mating portion 35 is located below the fixed wing plate 31. By making the mating portion 35 in sliding fit with the fixed wing plate 31 and located below the fixed wing plate 31, and by sliding the movable wing plate 32 relative to the fixed wing plate 31, the area of the upper surface of the mating portion 35 exposed to the outside can be changed. The area of the upper surface of the mating portion 35 exposed to the outside is the working area of the mating portion 35. The mating portion 35 can enable a sliding connection between the movable wing plate 32 and the fixed wing plate 31. By sliding the movable wing plate 32 relative to the fixed wing plate 31 to increase or decrease the working area of the mating portion 35, the opening area of the tail wing plate 30 can be increased or decreased, and the tail wing plate 30 can linearly change the opening area to meet the requirements for grip under different vehicle conditions.

[0052] For example, the movable wing plate 32 can slide away from the fixed wing plate 31 to the first position. At this time, the working area of the engaging portion 35 can be maximized, and the opening area of the tail wing plate 30 can be maximized. The tail wing plate 30 can maximize the function of increasing the vehicle's grip force. For another example, the movable wing plate 32 can also slide towards the fixed wing plate 31 to the second position, minimizing the working area of the engaging portion 35 and the opening area of the tail wing plate 30, so as to avoid excessive waste of energy caused by excessive increase in the vehicle's grip force. The movable wing plate 32 can also be between the first position and the second position, enabling the opening area of the tail wing plate 30 to vary according to different vehicle conditions. The tail wing plate 30 can provide different magnitudes of downward pressure according to the vehicle conditions.

[0053] Furthermore, the engaging portion 35 and the movable wing body 34 are connected by a stepped wall 36. In the sliding direction of the movable wing plate 32, the fixed wing plate 31 faces the stepped wall 36. The stepped wall 36 can play a role in limiting. For example, when the movable wing plate 32 is in the second position, the edge of the fixed wing plate 31 facing the movable wing plate 32 abuts against the stepped wall 36, which can limit the further movement of the movable wing plate 32 towards the fixed wing plate 31 and prevent the movable wing plate 32 from moving excessively towards the fixed wing plate 31 and causing damage to the movable wing plate 32 or other components. By making the fixed wing plate 31 face the stepped wall 36 in the sliding direction of the movable wing plate 32, the stepped wall 36 can more fully limit the fixed wing plate 31.

[0054] According to some embodiments of the present invention, with reference to Figure 3 and Figure 5 , the upper surface of the movable wing body 34 is flush with the upper surface of the fixed wing plate 31. By making the upper surface of the movable wing body 34 flush with the upper surface of the fixed wing plate 31, the upper surface of the tail wing plate 30 can be made integrally flat, reducing wind resistance.

[0055] According to some embodiments of the present invention, with reference to Figure 7, the movable wing plate 32 is slidable relative to the fixed wing plate 31. The first driving mechanism 12 includes a first motor 13 and two first transmission mechanisms 14. The two first transmission mechanisms 14 are disposed on the left and right sides of the first motor 13, and each first transmission mechanism 14 is drivably connected to the first motor 13 and the movable wing plate 32. The first motor 13 can drive the two first transmission mechanisms 14 to move. By making each first transmission mechanism 14 drivably connected to the first motor 13 and the movable wing plate 32, the movable wing plate 32 can be slid relative to the fixed wing plate 31. For example, the fixed wing plate 31 and the first motor 13 are fixed on the first mounting seat 11. By starting the first motor 13 to drive the first transmission mechanism 14 to move, the movable wing plate 32 is driven to move relative to the fixed wing plate 31, so as to achieve the purpose of increasing or decreasing the opening area of the tail wing plate 30. By disposing the two first transmission mechanisms 14 on the left and right sides of the first motor 13, the first transmission mechanism 14 can transmit the energy of the first motor 13 more evenly, making the opening and closing processes of the movable wing plate 32 more stable.

[0056] According to some embodiments of the present invention, referring to Figures 7-9 , the first transmission mechanism 14 includes a first transmission rod 15 and a gear-rack transmission mechanism 16. The first transmission rod 15 extends in the left-right direction. One end of the first transmission rod 15 is connected to the motor shaft of the first motor 13, and the first motor 13 is used to drive the first transmission rod 15 to rotate about its own central axis. By starting the first motor 13, the first transmission rod 15 can be driven to rotate about its own axis. The gear-rack transmission mechanism 16 includes a transmission gear 17 and a transmission rack 18 that mesh with each other. The transmission gear 17 is installed at the other end of the first transmission rod 15. The transmission gear 17 is coaxially arranged with the first transmission rod 15 and fixed relative to the first transmission rod 15. When the first transmission rod 15 rotates, it drives the transmission gear 17 to rotate synchronously. The transmission rack 18 extends in the front-back direction and is movable in the front-back direction. A connecting member 19 is provided on the rack. The upper end of the connecting member 19 is connected to the movable wing plate 32. The rotating transmission gear 17 drives the transmission rack 18 to move in the front-back direction, and the transmission rack 18 drives the movable wing plate 32 to move in the front-back direction.

[0057] For example, the first transmission rod 15 is fixedly connected to the transmission gear 17. When the vehicle speed is relatively high and the pressure sensor receives a relatively small wind pressure at the tail wing plate 30, the pressure sensor transmits a signal to the control unit. The control unit starts the first motor 13. The first motor 13 drives the first transmission rod 15 to rotate about its own axis, for example, drives the first transmission rod 15 to rotate forward, so that the transmission gear 17 rotates forward, thereby causing the transmission rack 18 to move backward. The moving wing plate 32 connected to the transmission rack 18 moves backward, and the opening area of the tail wing plate 30 increases. When the vehicle speed is relatively low and the pressure sensor receives a relatively large wind pressure, it transmits a signal to the control unit. The control unit starts the first motor 13. The first motor 13 drives the first transmission rod 15 to rotate about its own axis, for example, drives the first transmission rod 15 to rotate backward, so that the transmission gear 17 rotates backward, thereby causing the transmission rack 18 to move forward. The moving wing plate 32 connected to the transmission rack 18 moves forward, and the opening area of the tail wing plate 30 decreases.

[0058] According to some embodiments of the present invention, referring to Figures 7-9 , the tail wing assembly 100 further includes a rack seat 20. The rack seat 20 is detachably provided on the first mounting seat 11. A sliding groove 21 extending in the front-rear direction is formed on the rack seat 20. The transmission rack 18 is slidably provided in the sliding groove 21 in the front-rear direction. By slidably arranging the transmission rack 18 in the sliding groove 21 in the front-rear direction, it can play a role in limiting and guiding the movement of the transmission rack 18. The sliding groove 21 can play a role in limiting the transmission rack 18 in the left-right direction and can also play a role in guiding the transmission rack 18 in the front-rear direction, so that the transmission rack 18 can stably slide along the set direction. By making the rack seat 20 detachably provided on the first mounting seat 11, it is convenient to maintain or replace the rack seat 20. For example, the rack seat 20 is fixedly connected to the first mounting seat 11 through a fastener 40 such as a screw.

[0059] According to some embodiments of the present invention, referring to Figure 8 and Figure 9 , the first mounting seat 11 includes a first base 22 and a first mounting box 23. The first base 22 has a first mounting cavity 24. The first mounting box 23 is provided in the first mounting cavity 24. The bottom wall of the first mounting box 23 is spaced apart from the bottom wall of the first mounting cavity 24 to form an avoidance space 25. The first driving mechanism 12 is provided in the first mounting box 23. The first mounting box 23 can be used to accommodate the first driving mechanism 12, and the first mounting cavity 24 can be used to accommodate the first mounting box 23. The avoidance space 25 can be used to accommodate the fastener 40 between the rack seat 20 and the first mounting seat 11, such as a screw. By making the first mounting seat 11 include the first base 22 and the first mounting box 23, and making the bottom wall of the first mounting box 23 spaced apart from the bottom wall of the first mounting cavity 24 to form the avoidance space 25, the fastener 40 can be wrapped inside the first mounting base by the first mounting base, making it difficult to be disassembled from the outside, which can play an anti-theft role.

[0060] According to some embodiments of the present utility model, with reference to Figures 10-12 , the tail wing assembly 100 includes a second driving unit 60. The second driving unit 60 is disposed below the first driving unit 10. The second driving unit 60 includes a second mounting seat 61 and a second driving mechanism 62. The second driving mechanism 62 is disposed on the second mounting seat 61. The second driving mechanism 62 is connected to the first mounting seat 11 to drive the first mounting seat 11 to move. By driving the first mounting seat 11 to move with the second driving mechanism 62, for example, the first mounting seat 11 can be driven to move to adjust the height of the tail wing plate 30 and / or adjust the inclination angle of the tail wing plate 30.

[0061] According to some embodiments of the present utility model, the second driving mechanism 62 includes a second motor 63 and two second transmission mechanisms 71. The two second transmission mechanisms 71 are disposed on the left and right sides of the second motor 63. Each second transmission mechanism 71 is drivably connected to the second motor 63 and the first mounting seat 11. By disposing the two second transmission mechanisms 71 on the left and right sides of the second motor 63, the second transmission mechanisms 71 can more evenly transmit the energy of the second motor 63, making the process of adjusting the height and / or the angle of the first mounting seat 11 more stable.

[0062] In some alternative embodiments of the present utility model, the second transmission mechanism 71 includes a second transmission rod 64 and a link mechanism 65. The second transmission rod 64 extends in the left-right direction. One end of the second transmission rod 64 is connected to the motor shaft of the second motor 63. The second motor 63 is used to drive the second transmission rod 64 to rotate around its own central axis. The other end of the second transmission rod 64 is connected to the link mechanism 65. The link mechanism 65 is connected to the first mounting seat 11. The second transmission mechanism 71 can drive the first mounting seat 11 to move up and down, or drive the first mounting seat 11 to rotate, or drive the first mounting seat 11 to rotate while driving the first mounting seat 11 to move up and down.

[0063] Optionally, the link mechanism 65 may include a driving rod 66, a driven rod 67, an outer support link 68, an inner support link 69, and an upper support bracket 70. The upper support bracket 70 is connected to the first mounting seat 11. Starting the second motor 63, the second motor 63 can drive the second transmission rod 64 to rotate around the central axis of the transmission rod itself, thereby driving the driving rod 66 to rotate. The driving rod 66 drives the driven rod 67 to rotate, causing the outer support link 68, the inner support link 69, and the upper support bracket 70 to rotate, thereby lifting or lowering the tail wing plate 30, or adjusting the inclination angle of the tail wing plate 30, or adjusting the inclination angle of the tail wing plate 30 while lifting or lowering the tail wing plate 30.

[0064] For example, when the second motor 63 rotates forward, it drives the second transmission rod 64 to rotate forward around the central axis of the transmission rod itself, thereby driving the driving rod 66 to rotate forward. The driving rod 66 drives the driven rod 67 to rotate forward, causing the outer support connecting rod 68, the inner support connecting rod 69, and the upper bracket 70 to rotate. The link mechanism 65 extends, thereby lifting the tail fin plate 30 and increasing the tilt angle of the tail fin plate 30. When the tail fin plate 30 is lifted to the highest position, the link mechanism 65 is in the first state and the first mounting seat 11 is in the third position. When the second motor 63 rotates in reverse, it drives the second transmission rod 64 to rotate in reverse around the central axis of the transmission rod itself, thereby driving the driving rod 66 to rotate in reverse. The driving rod 66 drives the driven rod 67 to rotate in reverse, causing the outer support connecting rod 68, the inner support connecting rod 69, and the upper bracket 70 to rotate. The link mechanism 65 contracts, thereby lowering the tail fin plate 30 and reducing the tilt angle of the tail fin plate 30. When the tail fin plate 30 is lowered to the lowest position, the link mechanism 65 is in the second state and the first mounting seat 11 is in the fourth position.
