A retractable rear spoiler for a sports utility vehicle

Abstract

The invention relates to the technical field of auto parts, in particular to a retractable tail fin for a sports utility vehicle. The retractable tail fin includes a wing plate, a driving mechanism and a accommodating box, and the driving mechanism includes an active driving mechanism, Two passive driving mechanisms and two X-shaped lifting frames, the active driving mechanism includes a T-shaped block, a driving electric rod and two connecting rods. The passive drive mechanism includes a worm gear and a worm gear that is matched with the worm gear. The ends of the two connecting rods away from the T-shaped block are respectively hinged with the eccentric places of the two worm gears, and the two X-shaped lifting frames are respectively matched with the two worm gears. The driving mechanism of the present invention can drive the two ends of the wing plate to rise and fall synchronously, and drives the electric rod in the center of the accommodating box, reducing the load of driving the wing plate lifting and lowering, prolonging the service life of the driving mechanism, reducing the production cost and reducing the occupied space.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a retractable tail fin for a sports utility vehicle. Background technique [0002] SUV refers to a sports utility vehicle, which is a vehicle with the space function like a station wagon and the off-road capability of a cargo truck. 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 of the car makes the air resistance form a downward pressure, try to offset the lift, effectively control the down pressure of the air flow, and make the wind resistance coefficient corresponding Reduce, increase the high-speed driving stability of the car; because the rear wing can reduce the air resistance of the car, the installation of the rear wing on the high-speed car is also helpful for saving fuel, and also makes the appearance of the car more beautiful and plays a certain decorative role...

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.
