Definitions

  • the present invention relates to a car rear spoiler.
  • the present invention relates to a car rear spoiler, which can adjust the choke effect of a spoiler when the car is running to maintain wheel adhesion and vehicle stability.
  • the rear spoiler appeared on the trunk lid of the car.
  • the rear spoiler of the car is provided with supports at both ends of the spoiler. The supports are fastened to the trunk cover, and some are also provided in the middle of the spoiler. There is a fixed support. Because this car's rear spoiler is fixed, it plays the same choke function in all phases, states and road conditions of the vehicle at start and low, medium and high speed driving. , Can not adjust the choke effect with the change of wheel adhesion and vehicle stability, so the fixed rear choke reduces the vehicle's power and economy,
  • the object of the present invention is to provide a rear spoiler of a sedan that can adjust the choking effect with the change of wheel adhesion and vehicle stability. In this way, the dynamic performance of the vehicle at the time of starting and low and medium speed driving can be ensured , Economical, and can maintain the best wheel adhesion and vehicle stability and safety when the vehicle is driving at high speed.
  • a spoiler plate is provided above the tailgate cover of the car, and two ends of the spoiler plate are provided with supports, and the supports are fastened to the tailgate cover, wherein the spoiler plate The two ends are hinged to the support, and an oil cylinder is arranged in the middle below the spoiler.
  • the piston rod of the oil cylinder is connected to the spoiler.
  • the cylinder body of the oil cylinder is connected to the inner side below the tail box cover.
  • an oil cylinder is arranged below the spoiler, and the piston in the oil cylinder reciprocates, and the spoiler is driven to float up and down by the piston rod, so that the spoiler can be driven by the vehicle Under different speeds, various states and various road conditions, it constantly floats up and down, and constantly adjusts the choke effect of the choke plate, so that the vehicle maintains the best adhesion, and improves the stability, safety and power of the vehicle , Economical.

  • the choke plate 2 is installed above the tail box cover 4 through the support 3.
  • the spoiler 2 provided above the trunk lid 4 of the car is hinged on the support 3 via a hinge shaft 6 so that the spoiler 2 can move freely up and down on the support 3.
  • the support 3 can be fastened to the extension block 5 of the opening and closing page of the tail box cover 4 by using fastening bolts 14. In order to reduce the pressure on the opening and closing page of the tail box cover 4, the opening and closing page of the tail box cover 4 can be reduced.
  • the extension block 5 is provided with an adjusting nut 13 above and a fastening nut 15 below.
  • An oil cylinder 11 is provided in the middle of the lower part of the spoiler plate 2.
  • the oil cylinder 11 may be disposed inside the rear of the tailgate 4; the piston rod 10 of the oil cylinder 11 is connected to the spoiler plate 2.

  • a ball bearing is used, wherein a ball head seat 7 is provided at the lower middle of the spoiler 2, a ball head 8 is provided above the piston rod 10, and the piston rod 10 and the spoiler are connected through the ball head cover 1. 2 is articulated together.
  • the piston rod 10 and the choke plate 2 can also be hinged to each other by using a bracket and a hinge shaft. In this way, when the upper inlet and outlet port 16 of the oil cylinder 11 receives oil and the lower inlet and outlet port 18 returns oil, the piston 17 descends, thereby causing the choke plate 2 to float down; and when the upper and lower oil inlets 16 and 16 of the oil cylinder 11 drain oil, the piston 17 moves upward, thereby driving the choke plate 2 to float up and down. During movement, the spoiler 2 also floats up and down It is achieved the regulation of the baffle plate from the effect of the spoiler.
  • a dust cover 9 is set on the piston rod 10, which can prevent water, dust and other debris from entering the tail box.
  • the dust cover 9 is fixed at the two ends of the tail box cover 4 and the choke plate 2.

Abstract

Becquet pour véhicule de tourisme, de course ou analogue. Ce becquet comporte un déflecteur dont les extrémités latérales sont montées pivotantes sur des supports fixés au couvercle du coffre du véhicule. Un ensemble à vérin hydraulique est monté sous la partie intermédiaire du déflecteur du becquet et sa tige de piston est reliée activement audit déflecteur. Lors de l'utilisation, on peut faire pivoter le déflecteur vers le haut ou vers le bas par une commande et un réglage de la pression hydraulique à l'intérieur du cylindre. Par conséquent, on obtient une bonne adhérence au sol et on peut améliorer la tenue de route et la sécurité du véhicule.
