Retractable tail wing for practical sports automobile

Abstract

The invention relates to the technical field of automobile accessories, in particular to a retractable tail wing for a practical sports automobile, the retractable tail wing comprises a wing plate, a driving mechanism and a containing box, the driving mechanism comprises an active driving mechanism, two passive driving mechanisms and two X-shaped lifting frames, the active driving mechanism comprises a T-shaped block, a driving electric pole and two connecting rods, the T-shaped block is rotationally connected with the center of the containing box through a rotating shaft, the passive driving mechanism comprises worm wheels and worms in transmission fit with the worm wheels, and the ends, away from the T-shaped block, of the two connecting rods are hinged to the eccentric positions of the two worm wheels correspondingly; the two ends of the wing plate can be driven to ascend and descend synchronously, an electric pole is driven to be located in the center of the containing box, the load for driving the wing plate to ascend and descend is reduced, the service life of the driving mechanism is prolonged, the production cost is reduced, and the occupied space is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a retractable rear wing for a sports utility vehicle. Background technique [0002] SUV refers to a sports utility vehicle, which is a vehicle with space functions like a station wagon and the off-road capability of a truck. The rear wing of a car refers to the protrusion of a duck tail mounted on the rear end of the trunk lid of a car, which belongs to A part of the car aerodynamic kit, the main function is to reduce the lift at the rear of the vehicle. When the car is running at high speed, the rear wing makes the air resistance form a downward pressure, offsets the lift as much as possible, effectively controls the airflow down pressure, and makes the drag coefficient corresponding Reduce and increase the high-speed driving stability of the car; because the tail fin can reduce the air resistance of the car, the addition of the tail fin to the high-speed car is also helpful ...

AI Technical Summary

Problems solved by technology

[0003] However, the wing plates on the existing SUVs are all fixedly installed with a wing plate, which only plays a decorative role, and does not play a role in reducing air resistance. Tail lift generally adopts a single drive method, but the drive mechanism is set at one end of the wing plate, and the other end of the wing plate is equipped with an auxiliary lifting frame. Since the center of gravity is far away from the drive mechanism, the load on the drive mechanism is too large. Excessive damage to the drive mechanism and short service life. When the dual drive method is used to drive the flaps up and down, the flaps cannot be completely synchronized. The cost is high and the space occupied is large.
