[0031] The following describes embodiments of the present invention in detail. 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] In the related art, the tail wing assembly is an important component of the automobile aerodynamic kit, which can generate a downward pressure for the high-speed running automobile and provide a large ground adhesion for the automobile. The variable tail wing is different from the fixed tail wing, and the angle of the variable tail wing is adjustable. The conventional variable tail wing is connected with the tail wing through a plurality of connecting rods. The driving device drives the connecting rod to move, the connecting rod drives the tail wing to deflect, and the tail wing deflection angle reaches the preset angle. The limiting mechanism locks the connecting rod. The conventional tail wing deflection angle is limited, and it is difficult to realize the continuous adjustment of the tail wing deflection angle under the transformation of the vehicle in the acceleration, turning, braking and other states.

[0033] Reference will be made to the following Figure 1-Figure 5 A tail wing assembly for a vehicle according to an embodiment of the present application is described.

[0034] The tail wing assembly 1 according to the present application comprises a base 11, a cylinder body 13, a piston rod 14, a tail wing plate 12 and a control device. The base 11 is connected with the vehicle body. The cylinder body 13 is arranged on the base 11, and the cylinder body 13 is formed with an adjusting cavity 131 suitable for accommodating a pressure medium. The piston rod 14 is movably arranged in the adjusting cavity 131 and moves according to the damping change of the pressure medium. The tail wing plate 12 is connected with the piston rod 14 and moves with the piston rod 14. The control device is electrically connected with the cylinder body 13 and is suitable for adjusting the damping of the pressure medium by changing the current flowing to the cylinder body 13.

[0035] The tail wing assembly 1 in the present application is mainly composed of a base 11, a cylinder 13, a piston rod 14, a tail wing plate 12 and a control device. The base 11 can be connected to the top of the trunk at the rear of the vehicle to realize the connection between the tail wing assembly 1 and the vehicle body. An installation space suitable for accommodating at least part of the cylinder 13 is formed on the base 11. The cylinder 13 is arranged in the installation space and is fixed to the base 11 by screw connection, thereby limiting the movement of the cylinder 13 in the installation space along the direction of vehicle operation, thereby improving the stability and reliability of the cylinder 13 in the base 11. An adjustment chamber 131 is formed inside the cylinder 13. A pressure medium is arranged in the adjustment chamber 131. The damping of the pressure medium can be changed according to the magnetic field strength in the adjustment chamber 131. One end of the piston rod 14 is arranged in the adjustment chamber 131. The piston rod 14 can move along the cylinder 13 The inner wall of the piston rod 14 moves, and the other end of the piston rod 14 is connected to the tail wing plate 12. The position of the tail wing plate 12 can change with the movement of the piston rod 14. The control device can control the current flowing to the cylinder body 13. When the rear wing angle of the vehicle needs to be adjusted, the control device changes the current flowing to the cylinder body 13 to change the damping size of the pressure medium. The piston rod 14 can move according to the damping change of the pressure medium. The piston rod 14 can be fixed at different positions in the adjustment chamber 131. The length of the piston rod 14 extending out of the adjustment chamber 131 changes, thereby driving the tail wing plate 12 to deflect to meet the various driving conditions of the vehicle, thereby improving the stability and reliability of the vehicle under different driving conditions.

[0036] In some embodiments, the pressure medium can be configured as a magnetorheological fluid (MRF). MRF is a special type of liquid whose damping properties can be controlled by varying the strength of the magnetic field within the liquid. When the magnetic field strength increases, the particles of the MRF become more aligned, forming a lattice-like structure, thereby increasing friction and damping. When the magnetic field strength decreases, the particles become more loosely arranged, reducing damping.

[0037] Therefore, the vehicle needs to adjust the tail wing angle under different driving conditions. The tail wing assembly 1 increases or decreases the current flow flowing to the cylinder 13 through the control device, thereby controlling the magnetic field strength in the cylinder 13 to change the damping size of the magnetorheological fluid. The piston rod 14 moves according to the damping change of the magnetorheological fluid. The piston rod 14 can be fixed at various positions in the adjustment chamber 131. The length of the piston rod 14 extending out of the adjustment chamber 131 changes, thereby driving the tail wing plate 12 to deflect to meet the various driving conditions of the vehicle and improve the stability and reliability of the vehicle under different driving conditions.

[0038] According to the tail wing assembly 1 of the present invention, the control device changes the current flowing to the cylinder body 13, thereby changing the magnetic field strength in the adjustment chamber 131, so that the damping size of the pressure medium in the adjustment chamber 131 changes. The piston rod 14 can move according to the change of the damping in the adjustment chamber 131. The piston rod 14 can be fixed at various positions in the adjustment chamber 131. The length of the piston rod 14 extending out of the adjustment chamber 131 changes, thereby driving the tail wing plate 12 to deflect, so as to meet various driving conditions of the vehicle, thereby improving the stability and reliability of the vehicle under different driving conditions.

[0039] According to some embodiments of the present invention, the tail wing assembly 1 also includes an adjusting rod and an elastic member. The adjusting rod is movably arranged on the base 11, one end of the elastic member is connected to the end of the adjusting rod, and the adjusting rod can drive the elastic member to move toward a direction close to the base 11. The other end of the elastic member is connected to the tail wing plate 12. When the control device transmits current to the adjusting chamber 131, the damping of the pressure medium in the adjusting chamber 131 becomes larger, the piston rod 14 is fixed at a certain position in the adjusting chamber 131, and the adjusting rod drives the elastic member to move toward a direction close to the base 11, so that the elastic member stretches and generates a pulling force on the tail wing plate 12 toward the base 11. However, since the damping force on the piston rod 14 is greater than the pulling force on the tail wing plate 12, the elastic member deforms under two opposite forces, driving the tail wing plate 12 to deflect, so as to improve the stability and reliability of the vehicle during operation.

[0040] According to some embodiments of the present invention, the tail assembly 1 further comprises a support plate, which is disposed at one end of the adjustment rod and has a through hole formed therein for the piston rod 14 to pass through. When the vehicle is in motion, if the piston rod 14 tends to move in the forward direction of the vehicle, the piston rod 14 is blocked by the inner wall of the through hole, thereby limiting the movement of the piston rod 14 in the support plate in the direction of the vehicle's travel, thereby improving the stability and reliability of the piston rod 14 in the support plate. The through hole is arranged opposite the opening of the adjustment chamber 131, thereby making the positioning of the piston rod 14 more accurate, facilitating the installation of the piston rod 14 between the cylinder body 13 and the support plate, and improving the assembly efficiency of the piston rod 14. An elastic member is disposed between the support plate and the tail plate 12. When the elastic member is subjected to a force from the tail plate 12, the elastic member generates a force on the support plate toward the base 11, causing the support plate to drive the piston rod 14 disposed in the through hole toward the base 11, thereby changing the deflection angle of the tail plate 12 and improving the stability of the vehicle during operation.

[0041] According to some embodiments of the present invention, the piston rod 14 is constructed in multiple forms, and the cylinder body 13 is constructed in multiple forms corresponding to the piston rods 14 one by one. Each piston rod 14 is arranged in the cylinder body 13 corresponding thereto. The control device can be connected to the multiple cylinder bodies 13 separately. When the inclination angle of the tail wing needs to be adjusted, the control device can separately control the current flowing into different cylinder bodies 13. The magnetic field strength in each cylinder body 13 is different, so that the pressure medium damping in each cylinder body 13 is different. Since the piston rod 14 moves according to the change in the pressure medium damping, the position of the piston rod 14 in each cylinder body 13 is different, and the length of each piston rod 14 extending out of the cylinder body 13 is different, so that the position of the tail wing plate 12 is deflected at multiple angles compared with the initial position of the tail wing plate 12. The tail wing plate 12 can be deflected accordingly according to the form of the vehicle, thereby improving the stability and reliability of the vehicle during driving. The support plate is provided with through holes corresponding to the multiple piston rods 14 one by one. The multiple piston rods 14 are respectively arranged in the corresponding through holes, avoiding mutual interference between the multiple piston rods 14 and improving the accuracy of the vehicle tail deflection angle.

[0042] According to some embodiments of the present invention, one end of the adjusting rod is rotatably provided on the base 11, and the other end of the adjusting rod is connected to the support plate, thereby realizing the connection between the base 11 and the support plate. An external thread is formed on the outer periphery of the end of the adjusting rod away from the base 11, a threaded hole is formed on the support plate, and an internal thread is formed on the inner peripheral wall of the threaded hole. The internal thread cooperates with the external thread, which reduces the friction resistance between the adjusting rod and the support plate when the adjusting rod rotates, improves the transmission efficiency between the adjusting rod and the support plate, and improves the efficiency of the support plate in driving the piston rod 14 to move.

[0043] According to some embodiments of the present invention, the tail wing assembly 1 further includes a driving member, which is adapted to drive the adjusting rod to rotate.

[0044] In some specific embodiments, a driving member is also provided on the tail wing assembly 1. The driving member can be constructed as a piezoelectric motor. The output shaft of the piezoelectric motor is connected to the adjusting rod. The output shaft of the piezoelectric motor drives the adjusting rod to rotate. The adjusting rod drives multiple piston rods 14 set on the support plate to move together in a direction close to the base 11, or the adjusting rod drives multiple piston rods 14 set on the support plate to move together in a direction away from the base 11. At the same time, it can also ensure that the movement speed of multiple piston rods 14 is the same. When the vehicle tail wing does not need to adjust the angle, the control device does not supply current to the cylinder 13, the pressure medium damping remains unchanged, and the piezoelectric motor drives the adjusting rod to drive the piston rods 14 to move synchronously, ensuring that each piston rod 14 is located in the same position in different adjustment chambers 131, so that the tail wing plate 12 and the base 11 remain parallel, ensuring the stability and reliability of the tail wing plate 12 when it is in the initial state, and at the same time, the distance between the tail wing plate 12 and the base 11 can be adjusted.

[0045] In addition, the piezoelectric motor also has a power-off self-locking function. The piezoelectric motor can lock the adjustment rod in a certain position, thereby preventing the adjustment rod from driving the piston to move under the action of external force, thereby improving the stability of the tail wing plate 12 in a certain position.

[0046] According to some embodiments of the present invention, the piston rod 14 includes a first rod portion 141 and a second rod portion 142, one end of the first rod portion 141 is accommodated in the adjustment chamber 131; one end of the second rod portion 142 is connected to the other end of the first rod portion 141, and the other end of the second rod portion 142 is connected to the tail wing plate 12, and a deformation portion is formed between one end and the other end of the second rod portion 142 to be suitable for adjusting the angle of the tail wing plate 12.

[0047] The piston rod 14 is composed of a first rod portion 141 and a second rod portion 142. One end of the first rod portion 141 is accommodated in the regulating chamber 131. When the control device does not transmit current to the cylinder body 13, the driving member can drive the regulating rod to drive the first rod portion 141 to move along the inner wall of the cylinder body 13 to change the air pressure in the regulating chamber 131, so that the pressure medium can move in the regulating chamber 131, ensuring that the damping force applied to the first rod portion 141 at different positions in the regulating chamber 131 is the same, so as to maintain the stability and reliability of the vehicle rear wing when it is in the initial state. The first rod portion 141 can move according to the damping change of the pressure medium to change the position of the rear wing plate 12 and the base. The distance between the seats 11, the other end of the first rod 141 passes through the through hole of the support plate and is connected to one end of the second rod 142, and the other end of the second rod 142 is connected to the tail wing plate 12. A deformation portion is formed between one end and the other end of the second rod 142. When the first rod 141 transmits the pressure received to the second rod 142, the deformation portion deforms to a certain extent under the action of the force, and the tail wing plate 12 rotates with the deformation amplitude of the deformation portion, thereby realizing multi-angle deflection of the tail wing plate 12, meeting the needs of the vehicle for the deflection angle of the tail wing under different conditions during high-speed driving, and improving the stability and safety of the vehicle's operation.

[0048] According to some embodiments of the present invention, the diameter of the deformation portion gradually decreases in a direction toward one end and the other end of the second rod portion 142 .

[0049] In some specific embodiments, when the vehicle tail wing needs to be deflected at multiple angles, the first rod portion 141 moves towards the base 11 under the pressure of the elastic member and the support plate. Since the diameter of the first rod portion 141 is large, the contact area between the first rod portion 141 and the support plate is large, so that the force transmitted from the support plate to the first rod portion 141 is more uniform and stable, and the first rod portion 141 is not easy to deform. The second rod portion 142 is provided with a deformation portion, and the second rod portion 142 is connected with the first rod portion 141. When the pressure received by the first rod portion 141 is transmitted to the second rod portion 142, since the diameter of the deformation portion gradually decreases in the direction from the base 11 to the tail wing plate 12, the deformation amplitudes of different positions of the deformation portion are different after being stressed, thereby driving the tail wing plate 12 to be deflected at multiple angles.

[0050] According to some embodiments of the present application, one end of the first rod portion 141 forms a limiting plate 132, and the limiting plate 132 is provided with a communication hole 133 suitable for the flow of pressure medium.

[0051] The adjusting cavity 131 of the cylinder body 13 is further provided with a limiting plate 132, which divides the adjusting cavity 131 into a front adjusting cavity 131 and a rear adjusting cavity 131. The limiting plate 132 is further provided with a plurality of communication holes 133. In the state that the control device does not deliver current to the cylinder body 13, the output shaft of the driving member drives the adjusting rod to rotate, and the adjusting rod pulls the first rod portion 141 to slide along the inner wall surface of the cylinder body 13, so that the air pressure in the adjusting cavity 131 changes. The pressure medium flows between the front adjusting cavity 131 and the rear adjusting cavity 131 under the action of the air pressure through the communication hole 133, so as to ensure that the damping received by the first rod portion 141 at different positions in the adjusting cavity 131 is the same size, thereby maintaining the stability and reliability of the vehicle tail wing in the initial state.

[0052] In addition, the limiting plate 132 can also limit the movement of the first rod portion 141 in the adjusting cavity 131, so that the first rod portion 141 can only move between the front adjusting cavity 131 and the limiting plate 132, so that the error between the positions of the plurality of first rod portions 141 in the corresponding adjusting cavities 131 is reduced, thereby ensuring the accuracy of the deflection angle of the vehicle tail wing.
