Description

Technical Field

[0001] The present invention relates to the technical field of automotive spoilers, and specifically to an automotive spoiler with an adjustment mechanism. Background Art

[0002] During the driving process of a vehicle, there is a pressure difference between the upper side and the lower side of the vehicle body. This pressure difference can generate lift on the vehicle, resulting in a reduction in the tire grip and a tendency for the vehicle to float, thereby affecting the driving safety of the vehicle. In the related art, in order to reduce the lift generated during the high-speed driving of the vehicle, automotive spoilers are usually provided on the vehicle body to generate a downward pressure for offsetting the lift and increasing the adhesion of the vehicle to the ground during high-speed driving, thus being beneficial to improving the driving safety of the vehicle.

[0003] However, in the related art, most automotive spoilers of vehicles are integrally formed. Therefore, the automotive spoiler cannot be adjusted according to the driving speed during the driving process of the vehicle. That is to say, the downward pressure generated by the automotive spoiler during the driving process of the vehicle always remains the same, which cannot meet the usage requirements of the vehicle at different driving speeds.

[0004] Therefore, it is necessary to provide an automotive spoiler with an adjustment mechanism, which can adjust the height and angle of the automotive spoiler and check the state of the spoiler, so as to be applicable to various different driving speeds. Summary of the Invention

[0005] The purpose of the present invention is to provide an automotive spoiler with an adjustment mechanism to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: An automotive spoiler with an adjustment mechanism includes a support frame, a support plate, a wing plate, a control box, and an adjustment system. A distance sensor is fixedly connected inside the support frame, and the distance sensor is used to measure the distance between the bottom of the support plate and the inner bottom of the support frame.

[0007] A double-output shaft motor and a group of bearing seats are fixedly connected to the top of the support plate. Rotating shafts are fixedly connected to the output ends on both sides of the double-output shaft motor. The rotating shafts are respectively connected to the adjacent bearing seats by bearings. Cam wheels are fixedly connected to the rotating shafts. There are several groups of the cam wheels. The cam wheels are in contact with but not fixed to the wing plates, and are used to control the angle adjustment of the wing plates. A spring is fixedly connected to the top of the support plate. The tail of the left end of the wing plate is in a horizontal state, and the front part of the right end of the wing plate is in an inclined state with the direction downward. A spirit level is horizontally and fixedly connected to the bottom of the left end of the wing plate, and the spirit level is used to check whether the wing plate is in a horizontal state. An inclinometer is fixedly connected to the bottom surface of the front part of the wing plate, and the inclinometer is used to measure the inclination angle of the wing plate. A speed sensor is arranged in the control box and is used to detect the running speed of the vehicle. A chute and a motor 1 are fixedly connected inside the support frame.

[0008] The adjustment system is arranged inside the control box. The adjustment system includes an acquisition module, a control module, a time module, an anti-misoperation module, and an alarm module.

The speed module is electrically connected to the speed sensor, and the speed module is used to acquire the vehicle driving speed. The horizontal module is electrically connected to the spirit level, and the horizontal module is used to acquire whether the wing plate is in a horizontal state. The height module is electrically connected to the distance sensor, and the height module is used to convert the distance between the bottom of the support plate and the bottom inside the support frame into the height of the support plate rising. The height of the support plate rising is the distance between the bottom of the support plate and the bottom inside the support frame minus the height inside the support frame. The angle module is electrically connected to the inclinometer and is used to acquire the real-time angle of the wing plate adjustment. The time module is used for timing, and the alarm module is used for alarm prompting.

[0009] According to the above technical solution, there are two groups of the support frames. A bidirectional lead screw and a slider are arranged in the chute. The right end of the bidirectional lead screw passes through the chute and is fixedly connected to the motor 1. The bidirectional lead screw is connected to the chute by a bearing, and the bidirectional lead screw is threadedly connected to the slider.

[0010] There are two groups of the sliders. The sliders are slidably connected to the chute. A support rod 1 is hinged to the top of the left slider. A limit hole is formed in the support rod 1. A support rod 2 is hinged to the top of the right slider. The support rod 2 is hinged to the support rod 1 through the limit hole. The tops of the support rod 1 and the support rod 2 are respectively hinged to the support plate and are used to control the lifting of the support plate.

[0011] According to the above technical solution, fixed plates are fixedly connected to both ends of the support plate. The right side of the support plate is hinged to the wing plate. Guard plates are fixedly connected to both ends of the wing plate. The two groups of guard plates are respectively arranged outside the two groups of fixed plates. A baffle is hinged to the left end of the wing plate. A groove is formed in the left side of the top of the support plate. The bottom of the baffle is arranged in the groove. Limiting grooves are arranged on the opposite sides of the two fixed plates. A fixed shaft is fixedly connected to the bottom of the baffle. The fixed shaft is arranged in the limiting groove. The fixed shaft is slidably connected to the limiting groove, so as to form a sealed space among the baffle, the wing plate and the support plate. At the same time, the baffle can provide support for the wing plate.

[0012] According to the above technical solution, a plurality of groups of springs are provided. The springs are arranged on the left side of the double-output shaft motor. The top of the springs is fixedly connected to the wing plate. When the angle between the wing plate and the support plate is reduced, the pulling force is used to promote the reduction of the angle of the wing plate, so as to avoid the situation that the wing plate cannot contract due to the support of the baffle.

[0013] According to the above technical solution, the control box is arranged inside the vehicle. A display screen, a switching button and a control button are arranged on the control box. The display screen is used to display the real-time angle of the wing plate, the rising height of the support plate and the running speed of the vehicle. The switching button is used to switch the height and angle adjustment modes. The height and angle adjustment modes include automatic and manual controls. The control button is used to control the adjustment of the height and angle in the manual state.

[0014] According to the above technical solution, the control module is electrically connected to the first motor and the double-output shaft motor. The control module includes an automatic mode and a manual mode. An operation acquisition module and a locking module are arranged in the anti-misoperation module. The anti-misoperation module is automatically enabled in the manual mode and not enabled in the automatic mode. The operation acquisition module is used to acquire operation data. The locking module is used to lock the manual mode.

[0015] According to the above technical solution, the adjustment method of the vehicle spoiler is as follows:

[0016] Perform the lifting test, angle test and adjustment verification at the spoiler in advance to ensure that the support plate can be lifted and lowered normally and the wing plate can rotate normally when the vehicle starts, laying a foundation for the subsequent real-time adjustment of the height of the support plate and the angle of the wing plate during the vehicle operation.

[0017] During the vehicle operation, the height of the support plate and the angle of the wing plate are adjusted in real time, so that the downward pressure generated by the spoiler during the vehicle driving can be increased, and the driving safety can be improved;

[0018] Limit the switching between the manual mode and the automatic mode to ensure normal driving, avoid the frequent manual control of the lifting of the support plate and the rotation of the angle of the wing plate from distracting the driver's attention and reducing the service life of the vehicle spoiler, and further avoid potential safety hazards.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, by providing a first motor and a double-output shaft motor, the state of the wing plate can be checked when the vehicle starts, ensuring that the support plate is lifted and lowered and the wing plate is rotated according to the driving speed during the driving process of the vehicle;

[0020] By providing a spring and a baffle, the baffle can provide support for the wing plate when increasing the angle between the wing plate and the support plate, and the spring can use the pulling force to promote the reduction of the angle of the wing plate when reducing the angle between the wing plate and the support plate, avoiding the situation that the wing plate cannot contract due to the support of the baffle.

DETAILED DESCRIPTION OF THE INVENTION

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-7 , the present invention provides a technical solution: an automobile spoiler with an adjustment mechanism, including a support frame 1, a support plate 8, a wing plate 9, a control box 19 and an adjustment system. There are two groups of support frames 1, and the support frames 1 are fixed on the top of the automobile trunk, and the fixing methods include but are not limited to bolt fixing, glue fixing, etc.;

[0032] Refer to Figure 2 and Figure 3 , the inside of the support frame 1 is a cavity structure. A chute 2 and a first motor 7 are fixedly connected inside the support frame 1. A bidirectional lead screw 3 and a slider 4 are arranged in the chute 2. The right end of the bidirectional lead screw 3 passes through the chute 2 and is fixedly connected to the first motor 7. The bidirectional lead screw 3 is connected to the chute 2 by a bearing, and the bidirectional lead screw 3 is threadedly connected to the slider 4. There are two groups of sliders 4, and the sliders 4 are slidably connected to the chute 2. The top of the left slider 4 is hinged to a first support rod 5, a limiting hole is opened on the first support rod 5, the top of the right slider 4 is hinged to a second support rod 6, and the second support rod 6 is hinged to the first support rod 5 through the limiting hole. The top of the first support rod 5 and the top of the second support rod 6 are respectively hinged to the support plate 8;

[0033] 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 first motor 7 starts to rotate forward, the output end of the first motor 7 drives the bidirectional lead screw 3 to rotate forward, so that the two sliders 4 move towards each other along the direction of the chute 2, so that the first support rod 5 and the second support rod 6 adjust the inclination angle around the hinge point, and the top support plate 8 is lifted to realize the lifting of the support plate 8. On the contrary, when the first motor 7 starts to rotate reversely, it drives the support plate 8 to descend until it returns to the initial state. By controlling the forward and reverse rotation of the first motor 7 as described above, the rising and falling of the support plate 8 are realized, and the purpose of adjusting the height of the support plate 8 is achieved.

[0034] 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 chute 2, and 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.

[0035] Refer to Figure 2 , Figure 3 , Figure 4, both ends of the support plate 8 are fixedly connected with fixing plates 14. The right side of the support plate 8 is hinged to the wing plate 9. Both ends of the wing plate 9 are fixedly connected with guard plates 15. The two groups of guard plates 15 are respectively arranged outside the two groups of fixing plates 14. The left end of the wing plate 9 is hinged with a baffle 13. A groove is formed 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 fixing plates 14. The bottom of the baffle 13 is fixedly connected with a fixed shaft. The fixed shaft is arranged in the limiting groove 16. The fixed shaft is slidably connected with the limiting groove 16, so that a sealed space is formed between the baffle 13, the wing plate 9 and the support plate 8, improving the service life. At the same time, the baffle 13 provides support for the wing plate 9.

[0036] Reference Figure 2 , Figure 5 , Figure 6 , a double-output shaft motor 10 and a set of bearing seats are fixedly connected to the top of the support plate 8. 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 seats by bearings. A cam 12 is fixedly connected to the rotating shaft 11. There are several groups of cams 12. The cams 12 are in contact with but not fixed to the wing plate 9. When the double-output shaft motor 10 starts to rotate counterclockwise, it drives the cams 12 to rotate counterclockwise around the rotating shafts 11, gradually lifting the wing plate 9, so that the wing plate 9 rotates clockwise around the hinge with the support plate 8, achieving the purpose of adjusting the angle of the wing plate 9. While the wing plate 9 rotates clockwise, it drives the baffle 13 to rotate clockwise around the hinge with the wing plate 9 and slide at the bottom in the limiting groove 16, maintaining the sealed space formed with the wing plate 9 and the support plate 8, preventing 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.

[0037] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 , several groups of springs 17 are fixedly connected to the top of the support plate 8. The springs 17 are arranged on the left side of the double-output shaft motor 10. The top of the springs 17 is fixedly connected with the wing plate 9. When the wing plate 9 is lifted and forms a large angle with the support plate 8, the springs 17 stretch to provide a pulling force, so that the wing plate 9 continuously remains in contact with the cams 12. At the same time, it avoids the situation that when adjusting and reducing the angle between the wing plate 9 and the support plate 8 during vehicle driving, the wing plate 9 cannot rotate counterclockwise due to the support of the baffle 13, thus achieving the purpose of accurately adjusting the angle.

[0038] The tail part at the left end of the wing plate 9 is in a horizontal state, and the front part at the right end of the wing plate 9 is in an inclined state with the direction downward. A level 18 is horizontally fixedly connected to the bottom of the left end of the wing plate 9. The level 18 is used to check whether the wing plate 9 is in a horizontal state. It is possible to adjust the rotation of the first motor 7 according to whether the tail part at the left end of the wing plate 9 is in a horizontal state, that is, adjust the rising height of the support plate 8, so as to judge and eliminate the reason why the wing plate 9 is not in a horizontal state.

[0039] Reference Figure 7 At the front bottom surface of the wing plate 9, an inclinometer 20 is fixedly connected. The inclinometer 20 is arranged on the right side of the double-output shaft motor 10, and the inclinometer 20 is used to measure the inclination angle of the wing plate 9.

[0040] The control box 19 is arranged inside the vehicle. A display screen, a switching button and a control button are arranged on the control box 19. A speed sensor is arranged inside the control box 19. The speed sensor is used to detect the running speed of the vehicle. The display screen is used to display the real-time angle of the wing plate 9, the rising height of the support plate 8 and the running speed of the vehicle. The switching button is used to switch between the height and angle adjustment modes. The height and angle adjustment modes include automatic and manual controls. The control button is used to control the adjustment of height and angle in the manual state.

[0041] The adjustment system is arranged inside the control box 19. The adjustment system includes an acquisition module, a control module, a time module, an anti-misoperation module and an alarm module. The acquisition module includes a speed module, a horizontal module, a height module and an angle module. The speed module is electrically connected to the speed sensor. The speed module is used to acquire the driving speed of the vehicle. The horizontal module is electrically connected to the level 18. The horizontal module is used to acquire the data of the level 18 and then judge whether the left end tail of the wing plate 9 is in a horizontal state. The height module is electrically connected to the distance sensor 21. The height module is used to convert the distance between the bottom of the support plate 8 and the inner bottom of the support frame 1 into the rising height of the support plate 8. The distance between the bottom of the support plate 8 and the inner bottom of the support frame 1 minus the inner height of the support frame 1 is the rising height of the support plate 8. The angle module is electrically connected to the inclinometer 20 and is used to acquire the real-time angle of the adjustment of the wing plate 9. The control module is electrically connected to the first motor 7 and the double-output shaft motor 10. The control module includes an automatic mode and a manual mode. The automatic mode is for automatic control operations, and the manual mode is for manual control operations. The adjustment mode is controlled and selected by the switching button. The time module is used for timing. The anti-misoperation module is provided with an operation acquisition module and a locking module. The anti-misoperation module is automatically enabled in the manual mode and not enabled in the automatic mode. The operation acquisition module is used to acquire operation data, and the locking module is used to lock the manual mode. The alarm module is used for alarm prompts.

[0042] It should be noted that the initial state of the vehicle tail 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 ends of the cams 12 are in contact with the support plate 8 and the wing plate 9 respectively, and the automatic control is selected on the control box 19, which is the automatic mode.

[0043] The adjustment method of the vehicle tail wing with an adjustment mechanism is as follows:

[0044] Step 1: Perform the lifting test, angle test and adjustment verification at the tail wing in advance.

[0045] Specifically, Step 1-1: Lifting test.

[0046] Specifically, when the vehicle starts, the control module controls the first motor 7 to start rotating forward, driving the bidirectional lead screw 3 to rotate forward, causing the two sets of sliders 4 to move relatively closer, enabling the first support rod 5 and the second support rod 6 to rotate around the hinge point, lifting the top support plate 8, and realizing the lifting of the support plate 8. Conversely, when the first motor 7 starts rotating in reverse, it drives the support plate 8 to descend.

[0047] If the support plate 8 cannot be lifted or lowered during the lifting test, repeat this step, at most repeat it twice. If the support plate 8 still cannot be lifted or lowered after repetition, an alarm prompt will be given, indicating that the lifting test is abnormal.

[0048] Step 1-2: Angle test.

[0049] Specifically, the control module controls the double-output shaft motor 10 to start rotating counterclockwise, driving the cam 12 to rotate counterclockwise around the rotating shaft 11, gradually lifting the wing plate 9, causing the wing plate 9 to rotate clockwise around the hinge point 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 point with the wing plate 9 and slide at the bottom in the limit groove 16. At the same time, the baffle 13 provides support for the wing plate 9. Conversely, when the double-output shaft motor 10 starts rotating clockwise, the angle between the wing plate 9 and the support plate 8 is reduced.

[0050] If the wing plate 9 cannot adjust the angle during the angle test, repeat this step, at most repeat it twice. If the wing plate 9 still cannot adjust the angle after repetition, an alarm prompt will be given, indicating that the angle test is abnormal.

[0051] Step 1-3: Adjustment verification.

[0052] Specifically, the acquisition module acquires relevant information. During the lifting test, the horizontal module acquires the horizontal condition of the wing plate 9, and the height module acquires the height data of both ends of the support plate 8 lifted measured by the two distance sensors 21. During the angle test, the angle module acquires the rotation angle of the wing plate 9 for adjustment verification to ensure that the vehicle spoiler can be used normally during the vehicle operation.

[0053] When the acquisition module acquires that the surface of the wing plate 9 is horizontal during the lifting test, the heights of the support plate 8 during lifting are consistent, and the rotation angle of the wing plate 9 increases and decreases stably during the angle test, it means that the lifting test is normal and the angle test is normal.

[0054] During the lifting test, when the surface of the wing plate 9 is not horizontal and the heights on both sides of the support plate 8 are inconsistent during lifting, it is fed back to the control module. During the lifting process, the control module controls the motor 1 on the side with a larger lifting height to reduce the rotation speed, thereby reducing the distance between the two groups of sliders 4, slowing down the lifting speed on this side, making the heights on both sides of the support plate 8 consistent, then controlling the motor 1 on this side to increase the rotation speed, making the lifting speeds on both sides of the support plate 8 consistent, and recording the rotation speed of the motor 1 on this side at this time; afterwards, the horizontal module collects the horizontal condition of the surface of the wing plate 9 again. If the wing plate 9 is horizontal at this time, it is due to the inconsistent rotation speeds of the two motors 1 causing the inconsistent lifting speeds of the support plate 8, thus affecting the horizontal state of the wing plate 9. It is necessary to repeat the lifting test according to the rotation speed of the motor 1 on the corresponding side in the situation record.

[0055] If during this repeated lifting test process, the wing plate 9 cannot continuously maintain a horizontal state, then the lifting test is abnormal, which is fed back to the alarm module for alarm prompting, and the motor 1 cannot normally control the lifting of the support plate 8; if during this repeated inspection process, the wing plate 9 can continuously maintain a horizontal state, then the production test is normal. During the driving process of the vehicle, the lifting of the support plate 8 can be controlled according to the rotation speed of the motor 1 on the corresponding side in the situation record, ensuring that the lifting speeds on both sides of the support plate 8 are consistent during the lifting process in this case, that is, enabling the wing plate 9 to continuously maintain a horizontal state.

[0056] When the surface of the wing plate 9 is not horizontal but the heights on both sides are consistent when the support plate 8 is lifted, it is due to the deformation of the wing plate 9 causing an abnormal lifting test, which is fed back to the alarm module for alarm prompting. It is necessary to adjust or replace the wing plate 9, and the angle test is not performed.

[0057] After the lifting test is normal, the lifting test is performed again while the angle test is carried out. If the angle adjustment has a sudden change when the double-output shaft motor 10 drives the wing plate 9 to rotate and increase the angle, then the cam 12 is abnormal and needs to be replaced; if the angle adjustment is slow or even there is no change in the angle when the double-output shaft motor 10 drives the wing plate 9 to rotate and reduce the angle, it is due to the aging of the spring 17 and the reduction of its elasticity, which cannot normally drive the wing plate 9 to rotate counterclockwise and fit the cam 12. It is necessary to replace the spring 17 to ensure that the angle adjustment of the wing plate 9 can be carried out normally.

[0058] Step 2: Adjust the height of the support plate 8 and the angle of the wing plate 9 in real time during the operation of the vehicle.

[0059] Specifically, during the operation of the vehicle, the speed module collects the actual speed of the vehicle. In the automatic mode, speed thresholds for the height adjustment of the support plate 8 and the angle adjustment of the wing plate 9, as well as the corresponding height and angle adjustment values at different speeds, are set. Based on the speed thresholds, for every increase of X km / h in speed, the support plate 8 rises by h, and the angle between the wing plate 9 and the support plate 8 increases by a. The control module then controls the first motor 7 to start rotating forward, driving the bidirectional lead screw 3 to rotate forward, causing the two sets of sliders 4 to move relatively closer. This makes the first support rod 5 and the second support rod 6 rotate around the hinge point, lifting the top support plate 8. When the height module detects that the lifted height reaches the height adjustment value, the control module controls the first motor 7 to stop. At the same time, the control module controls the double-output shaft motor 10 to start rotating counterclockwise, driving the cam 12 to rotate counterclockwise around the rotating shaft 11, gradually lifting the wing plate 9 and increasing the angle between the wing plate 9 and the support plate 8. 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 reach the highest position and the wing plate 9 to open to the maximum angle, no further adjustment operations for increasing the height and angle are performed according to the height and speed adjustment values.

[0060] During deceleration, 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 decrease of X km / h in speed, the support plate 8 drops by h, and the angle between the wing plate 9 and the support plate 8 decreases by a. The control module controls the first motor 7 to start rotating in reverse, driving the support plate 8 to drop until the dropped height reaches the height adjustment value, then controls the first motor 7 to stop. The control module controls the double-output shaft motor 10 to start rotating clockwise, driving the angle between the wing plate 9 and the support plate 8 to decrease. When the decreased 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 and the wing plate 9 to return to the initial state, no further adjustment operations for decreasing the height and angle are performed according to the height and speed adjustment values.

[0061] Step 3: Define the switching between the manual mode and the automatic mode to ensure normal driving.

[0062] Specifically, the driver switches the automatic mode to the manual mode through the switching button on the control box 19. The time module performs continuous timing and sets the continuous timing interval and the recovery time. During the continuous timing interval, the operation acquisition module collects the actual number of operations. An operation count threshold is set in the operation acquisition module. When the actual number of operations reaches the operation count 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, thus avoiding the reduction of the driver's attention and the service life of the vehicle spoiler caused by continuous accidental touches or frequent control of the lifting of the support plate 8 and the angle adjustment of the wing plate 9, and further avoiding potential safety hazards.

[0063] Through the above steps, it is possible to detect the lifting condition of the support plate 8 and the adjustment condition of the wing plate 9 when the vehicle starts, ensuring normal operation during vehicle driving. It can automatically adjust the lifting height of the support plate 8 and the angle of the wing plate 9. When the actual speed does not reach the speed threshold, no height or angle adjustment is performed. Only when the actual speed reaches the speed threshold, height and angle adjustments are made. It is applicable to different driving speeds, and it is also possible to select and switch to the manual mode for manual control, preventing accidental touch and improving driving safety.
