Problems solved by technology

However, due to the complex speed changes during the driving process of the car, the rear pressure required by different speeds is different.
The existing rear spoiler design of automobiles cannot adjust the height and inclination angle of the spoiler with the change of vehicle speed. For high-speed vehicles, it is impossible to adjust the pressure of the rear of the vehicle in a timely manner; for low-speed vehicles, the spoiler not only It is difficult to play a practical role, and it will also increase the wind resistance of the car and reduce the fuel economy of the car

Embodiment Construction

[0031] Such as figure 1 with figure 2 As shown, the present invention has a spoiler control device and a control method for adjusting the height and inclination angle of the spoiler according to the working conditions of the vehicle. The box body 1 is fixed to the vehicle body by screws, the fixed bottom cover 4 is connected to the support rod 5 by threads, the return spring 2 is clamped between the fixed bottom cover 4 and the control mechanism housing 1, and the shape of the cam 5 describes how the cam changes over time. At the same time, the law of motion is transmitted to the top spoiler 6 through the fixed top cover 4 and the support rod 5 that are in point-to-surface contact with it. The height control shaft 14 and the angle control shaft 15 are connected with the cam 5 and the gear 8 with the control shafts 14 and 15 through key grooves, and the angle control shaft 15 and the height adjustment shaft 14 are fixed to the control box body 1 through bearings. The gear 9...

Abstract

The invention discloses a height-and-inclination-angle-adjustable spoiler control device and a control method thereof. The height-and-inclination-angle-adjustable spoiler control device comprises a control unit, a switch unit, a spoiler, a lifting drive unit, a lifting unit, a rotation angle drive unit and a rotation angle unit, the lifting drive unit comprises a height execution motor, and the rotation angle drive unit comprises a rotation angle execution motor. The control unit is electrically connected with the switch unit, the lifting drive unit and the rotation angle drive unit, and the spoiler is connected with the lifting unit which is electrically connected with the lifting drive unit. The spoiler is connected with the rotation angle unit which is electrically connected with the rotation angle drive unit. The height execution motor drives the lifting unit to enable the same to drive the spoiler to ascend and descend, and the rotation angle execution motor drives the rotation angle unit to enable the same to drive the spoiler to control inclination angle. Therefore, under different working conditions, an automobile is improved to be capable of timely maintaining complete automobile stability and fuel economy.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a spoiler control device capable of adjusting height and inclination angle and a control method thereof. Background technique [0002] At present, with the advancement of science and technology, the increasing level of people's consumption, and the urbanization of the working environment, people rely more and more on cars for travel, and cars have become more and more important means of transportation in people's lives. Existing spoiler research mainly focuses on the design of the spatial structure of the top spoiler, which can achieve the minimum wind resistance and high-speed stability of the car to a certain extent. However, due to the complex changes in vehicle speed during driving, the rear pressure required by different vehicle speeds is different. The existing rear spoiler design of automobiles cannot adjust the height and inclination angle of the spoiler with the change of veh...
