Description

Technical Field

[0001] The invention relates to the technical field of automobile tail wings, in particular to an automobile tail wing with an adjusting mechanism. Background Art

[0002] When a vehicle is driving, there is a pressure difference between the upper side and the lower side of the vehicle body. The pressure difference can generate lift on the vehicle, resulting in reduced wheel grip and a tendency for the vehicle to float, which in turn affects the driving safety of the vehicle. In the related art, in order to reduce the lift generated by the vehicle during high-speed driving, a rear wing is usually provided on the vehicle body to generate downforce to offset the lift, increase the vehicle's adhesion to the ground during high-speed driving, and thus help improve the driving safety of the vehicle.

[0003] However, in the related art, the rear wings of most vehicles are integrally formed, so the rear wings cannot be adjusted according to the driving speed of the vehicle. In other words, the downforce generated by the rear wings during the driving of the vehicle always remains consistent, which cannot meet the use requirements of the vehicle at different driving speeds.

[0004] Therefore, it is necessary to provide a car rear wing with an adjustment mechanism, which can adjust the height and angle of the car rear wing and check the state of the rear wing, so as to be suitable for various driving speeds. Summary of the invention

A support rod 26 is hinged on the top of the right slider 4. The support rod 26 is hinged to the support rod 15 through the limited hole. The top of the support rod 15 and the top of the support rod 26 are respectively hinged to the support plate 8; The initial state of the support plate 8 is that the bottom of the support plate 8 is flush with the top of the support frame 1, so that a closed space is formed inside the support frame 1. When the motor 1 7 starts to rotate forward, the output end of the motor 1 7 drives the bidirectional lead screw 3 to rotate forward, so that the two sets of sliders 4 move toward each other along the direction of the slide groove 2, so that the support rod 1 5 and the support rod 2 6 are adjusted to the inclination angle around the hinge, and the top support plate 8 is lifted up to realize the lifting of the support plate 8. Conversely, the motor 1 7 starts to reverse and drives the support plate 8 to descend until it returns to the initial state. The above-mentioned control of the forward and reverse rotation of the motor 1 7 realizes the rising and falling of the support plate 8, thereby achieving the purpose of adjusting the height of the support plate 8.

[0018] refer to Figure 5 , Figure 7 A distance sensor 21 is fixedly connected to the inner bottom of the support frame 1 . The distance sensor 21 is arranged on the left side of the slide slot 2 . The distance sensor 21 is used to measure the distance between the bottom of the support plate 8 and the inner bottom of the support frame 1 .

[0019] refer to Figure 2 , Figure 3 , Figure 4 , the two ends of the support plate 8 are fixedly connected with fixed plates 14, the right side of the support plate 8 is hinged with the wing plate 9, and the two ends of the wing plate 9 are fixedly connected with guard plates 15. The two groups of guard plates 15 are respectively arranged on the outside of the two groups of fixed plates 14. The left end of the wing plate 9 is hinged with a baffle 13. A groove is opened on the left side of the top of the support plate 8. The bottom of the baffle 13 is arranged in the groove. A limiting groove 16 is arranged on the opposite side of the two groups of fixed plates 14. A fixed shaft is fixedly connected to the bottom of the baffle 13, and the fixed shaft is arranged in the limiting groove 16. The fixed shaft is slidably connected to the limiting groove 16, so that the baffle 13 forms a closed space between the wing plate 9 and the support plate 8, thereby improving the service life. At the same time, the baffle 13 provides support for the wing plate 9.

[0020] refer to Figure 2 , Figure 5 , Figure 6 A double-output shaft motor 10 and a group of bearing seats are fixedly connected to the top of the support plate 8. The output ends on both sides of the double-output shaft motor 10 are respectively fixedly connected with rotating shafts 11. The rotating shafts 11 are respectively connected to the adjacent bearing seat bearings. A cam 12 is fixedly connected to the rotating shaft 11. The cam 12 is provided with several groups. The cam 12 contacts with the wing plate 9 but is not fixed. The double-output shaft motor 10 starts to rotate counterclockwise, driving the cam 12 to rotate counterclockwise around the rotating shaft 11, gradually lifting the wing plate 9, so that the wing plate 9 rotates clockwise around the hinge with the support plate 8, so as to achieve the purpose of adjusting the angle of the wing plate 9. When the wing plate 9 rotates clockwise, it drives the baffle 13 to rotate clockwise around the hinge with the wing plate 9, and the bottom slides in the limit groove 16 to maintain the enclosed space formed with the wing plate 9 and the support plate 8 to prevent rainwater from entering the interior in rainy weather. At the same time, the baffle 13 can provide support for the wing plate 9 to ensure the accuracy of angle adjustment.

[0021] refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 A spring 17 is fixedly connected to the top of the support plate 8, and several groups of springs 17 are arranged. The spring 17 is arranged on the left side of the dual-output shaft motor 10. The top of the spring 17 is fixedly connected to the wing plate 9, which is used to stretch the wing plate 9 when it is lifted up and forms a large angle with the support plate 8, so as to provide a pulling force so that the wing plate 9 continues to keep in contact with the cam 12. At the same time, it avoids the situation in which the wing plate 9 cannot rotate counterclockwise due to the support of the baffle 13 when adjusting and reducing the angle between the wing plate 9 and the support plate 8 during vehicle driving, thereby achieving the purpose of accurately adjusting the angle.

[0022] The tail of the left end of the wing plate 9 is in a horizontal state, the front of the right end of the wing plate 9 is in a downward inclined state, and a spirit level 18 is fixedly connected to the bottom of the left end of the wing plate 9 horizontally. The spirit level 18 is used to check whether the wing plate 9 is in a horizontal state. The rotation of the motor 7 can be adjusted according to whether the tail of the left end of the wing plate 9 is in a horizontal state, that is, the height of the support plate 8 is adjusted to determine and eliminate the reason why the wing plate 9 is not in a horizontal state.

[0023] refer to Figure 7 The front bottom surface of the wing plate 9 is fixedly connected with an inclinometer 20 . The inclinometer 20 is arranged on the right side of the double-output shaft motor 10 . The inclinometer 20 is used to measure the inclination angle of the wing plate 9 .

[0024] The control box 19 is arranged inside the car, and a display screen, a switch button and a control button are arranged on the control box 19. A speed sensor is arranged inside the control box 19, and the speed sensor is used to detect the running speed of the car.

The switch button is used to switch the height and angle adjustment mode. The height and angle adjustment mode includes automatic and manual control. The control button is used to control the height and angle adjustment in the manual state.

[0025] The adjustment system is arranged inside the control box 19, and the adjustment system includes an acquisition module, a control module, a time module, an anti-false touch module and an alarm module. The acquisition module includes a speed module, a level module, a height module and an angle module. The speed module is electrically connected to the speed sensor, and the speed module is used to collect the vehicle speed. The level module is electrically connected to the level meter 18, and the level module is used to collect the data of the level meter 18 to determine whether the left end of the wing plate 9 is in a horizontal state. The height module is electrically connected to the distance sensor 21, and the height module is used to convert the distance between the bottom of the support plate 8 and the bottom of the support frame 1 into the height of the support plate 8. The height of the support plate 8 is obtained by subtracting the internal height of the support frame 1 from the distance. The angle module is electrically connected to the inclinometer 20 and is used to collect the real-time angle of the wing plate 9 adjustment. The control module is electrically connected to the motor 7 and the dual-axis motor 10. The control module includes an automatic mode and a manual mode. The automatic mode is an automatic control operation, and the manual mode is a manual control operation. The adjustment mode is selected by controlling the switch button. The time module is used for timing. The anti-mistaken touch module is provided with an operation collection module and a locking module. The anti-mistaken touch module is automatically enabled in the manual mode and not enabled in the automatic mode. The operation collection module is used to collect operation data, the locking module is used to lock the manual mode, and the alarm module is used for alarm prompts.

[0026] It should be noted that the initial state of the automobile rear wing with an adjustment mechanism is that the bottom of the support plate 8 is flush with the top of the support frame 1, the protruding end of the cam 12 is in contact with the support plate 8 and the wing plate 9 respectively, and automatic control is selected on the control box 19, that is, the automatic mode.

[0027] The adjustment method of the car rear wing with an adjustment mechanism is as follows: Step 1: Perform lift test, angle test and adjustment verification on the tail wing in advance.

[0028] Specifically, step 1-1: lifting test.

[0029] Specifically, when the car starts, the control module controls the motor 1 7 to start forward rotation, driving the bidirectional screw 3 to rotate forward, so that the two sets of sliders 4 move relatively close to each other, so that the support rod 1 5 and the support rod 2 6 rotate around the hinge, and the top support plate 8 is lifted, so that the support plate 8 is lifted. Conversely, the motor 1 7 starts reverse rotation, driving the support plate 8 to descend.

[0030] If the support plate 8 cannot be raised or lowered during the lifting test, repeat this step up to twice. If the support plate 8 still cannot be raised or lowered after repetition, an alarm is issued to indicate that the lifting test is abnormal.

[0031] Step 1-2: Angle test.

[0032] Specifically, the control module controls the double-output shaft motor 10 to start counterclockwise rotation, driving the cam 12 to rotate counterclockwise around the rotating shaft 11, gradually lifting the wing plate 9, so that the wing plate 9 rotates clockwise around the hinge with the support plate 8, increasing the angle between the wing plate 9 and the support plate 8. When the wing plate 9 rotates clockwise, it drives the baffle 13 to rotate clockwise around the hinge with the wing plate 9 and the bottom slides in the limit groove 16. At the same time, the baffle 13 provides support for the wing plate 9. Conversely, the double-output shaft motor 10 starts to rotate clockwise, reducing the angle between the wing plate 9 and the support plate 8.

[0033] If the wing plate 9 cannot adjust the angle during the angle test, repeat this step up to twice. If the wing plate 9 still cannot adjust the angle after repeated steps, an alarm will be issued to indicate that the angle test is abnormal.

[0034] Steps 1-3: Adjustment and verification.

[0035] Specifically, the acquisition module collects relevant information. During the lifting test, the horizontal module collects the horizontal condition of the wing panel 9, and the height module collects the height data of the two ends of the support plate 8 measured by two sets of distance sensors 21. During the angle test, the angle module collects the rotation angle of the wing panel 9 and performs adjustment and verification to ensure that the car rear wing can be used normally during the operation of the car.

[0036] When the acquisition module collects that the surface of the wing plate 9 is horizontal in the lifting test, the height of the support plate 8 is consistent when it is lifted and lowered, and the rotation angle of the wing plate 9 increases and decreases steadily in the angle test, the lifting test is normal and the angle test is normal.

[0037] During the lifting test, when the surface of the wing plate 9 is not level and the heights of the two sides of the support plate 8 are inconsistent, feedback is sent to the control module. During the lifting process, the control module controls the motor 7 on the side with a larger lifting height to reduce the speed, thereby reducing the distance between the two sets of sliders 4, slowing down the lifting speed of this side, making the heights of the two sides of the support plate 8 consistent, and then controlling the motor 7 on this side to increase the speed, so that the lifting speeds of the two sides of the support plate 8 are consistent, and recording the speed of the motor 7 on this side at this time; then the horizontal module collects the horizontal situation of the surface of the wing plate 9 again. If the wing plate 9 is horizontal at this time, it is because the speeds of the two sets of motors 7 do not match, resulting in inconsistent control of the lifting speed of the support plate 8, thereby affecting the horizontal state of the wing plate 9. It is necessary to repeat the lifting test according to the speed of the motor 7 on the corresponding side in the situation record.

[0038] If the wing panel 9 cannot remain in a horizontal state during the repeated lifting test, the lifting test is abnormal and the alarm module is fed back to issue an alarm prompt, indicating that the motor 7 cannot normally control the support plate 8 to lift. If the wing panel 9 can remain in a horizontal state during the repeated inspection, the production test is normal. During the driving of the car, the support plate 8 can be lifted according to the rotation speed of the motor 7 on the corresponding side in the situation record to ensure that the lifting speeds of both sides of the support plate 8 remain consistent during the lifting process, so that the wing panel 9 can remain in a horizontal state continuously.

[0039] When the surface of the wing panel 9 is not level but the heights of both sides are consistent when the support plate 8 is raised, the deformation of the wing panel 9 causes an abnormal lifting test, which is fed back to the alarm module to issue an alarm prompt. The wing panel 9 needs to be adjusted or replaced, and the angle test is not performed.

[0040] After the lifting test is normal, perform the lifting test again and perform the angle test at the same time. If the angle adjustment changes suddenly when the double-shaft motor 10 drives the wing plate 9 to rotate to increase the angle, the cam 12 is abnormal and the cam 12 needs to be replaced; if the angle adjustment is slow or even the angle does not change when the double-shaft motor 10 drives the wing plate 9 to rotate to reduce the angle, it is because the spring 17 is aging and its elasticity is reduced, and it cannot drive the wing plate 9 to rotate counterclockwise normally and fit the cam 12. The spring 17 needs to be replaced to ensure that the angle adjustment of the wing plate 9 can be performed normally.

[0041] Step 2: Adjust the height of the support plate 8 and the angle of the wing plate 9 in real time while the car is running.

[0042] Specifically, during the operation of the vehicle, the speed module collects the actual speed of the vehicle, and sets the speed thresholds for the height adjustment of the support plate 8 and the angle adjustment of the wing plate 9 and the height and angle adjustment values ​​corresponding to the speed in the automatic mode. The height and angle adjustment values ​​are based on the speed thresholds. For every increase in speed by X km / h, the support plate 8 is raised by h, and the angle a between the wing plate 9 and the support plate 8 is increased. The control module is used to control the motor 1 7 to start forward rotation, drive the bidirectional screw rod 3 to rotate forward, so that the two sets of sliders 4 move relatively close to each other, and the support rod 1 5 and the support rod 2 6 rotate around the hinge to push the top support plate 8 to the top. When the height module collects the lifting height as the height adjustment value, the control module controls the motor 7 to stop, and at the same time, the control module controls the double-output shaft motor 10 to start counterclockwise rotation, driving the cam 12 to rotate counterclockwise around the rotating shaft 11, gradually lifting the wing plate 9, increasing the angle between the wing plate 9 and the support plate 8, and when the increased angle between the wing plate 9 and the support plate 8 reaches the angle adjustment value, the control module controls the double-output shaft motor 10 to stop. When the control module controls the support plate 8 to rise to the highest and the wing plate 9 to open to the maximum angle, the height and angle adjustment operations are no longer performed according to the height and speed adjustment values. When decelerating, the speed at the initial deceleration is replaced by the speed threshold, and the height adjustment value of the support plate 8 and the angle adjustment value of the wing plate 9 corresponding to the speed remain unchanged. For every X km / h reduction in speed, the support plate 8 is reduced by h, and the angle a between the wing plate 9 and the support plate 8 is reduced. The control module controls the motor 7 to start reversing, and drives the support plate 8 to be lowered to the height adjustment value. When the height is reduced to the height adjustment value, the motor 7 is controlled to stop, and the double-output shaft motor 10 is controlled to start rotating clockwise, driving the angle between the wing plate 9 and the support plate 8 to be reduced. When the reduced angle between the wing plate 9 and the support plate 8 reaches the angle adjustment value, the double-output shaft motor 10 is controlled to stop. When the control module controls the support plate 8 and the wing plate 9 to the initial state, the height reduction and angle reduction adjustment operations are no longer performed according to the height and speed adjustment values.

[0043] Step 3: Limit the switching between manual mode and automatic mode to ensure normal driving.

[0044] Specifically, the driver switches the automatic mode to the manual mode through the switch button on the control box 19, and the time module performs continuous timing and sets the continuous timing interval and recovery time. During the continuous timing interval, the operation collection module collects the actual number of operations. The operation collection module is provided with an operation number threshold. When the actual number of operations reaches the operation number threshold, the locking module locks the manual mode and automatically switches to the automatic mode. At this time, the time module continues to perform continuous timing. After the timing reaches the recovery time, the manual mode can be switched again, thereby avoiding continuous mis-touch or frequent control of the lifting and lowering of the support plate 8 and the angle adjustment of the wing plate 9, which may reduce the driver's attention and reduce the life of the car's rear wing, thereby avoiding safety hazards.

[0045] Through the above steps, the lifting and lowering conditions of the support plate 8 and the adjustment conditions of the wing plate 9 can be detected when the car starts, ensuring that the car can operate normally during driving. The lifting height of the support plate 8 and the angle of the wing plate 9 can be automatically adjusted, and when the actual speed does not reach the speed threshold, the height and angle adjustments are not performed. The height and angle adjustments are performed only after the actual speed reaches the speed threshold. It is suitable for different driving speeds, and you can also choose to switch to manual mode for manual control and prevent accidental touches, thereby improving driving safety.
