Abstract

The utility model discloses a novel self-adapted car tail fin comprising a car tail fin, wherein the car tail fin is fixed with a triangular adjusting plate; and the triangular adjusting plate is respectively connected with a main hydraulic retractable bracket and a secondary hydraulic retractable bracket through a main pin shaft and a secondary pin shaft. The main hydraulic retractable bracket and the secondary hydraulic retractable bracket are connected with a sensor through signal lines. According to the novel self-adapted car tail fin disclosed by the utility model, self-adaption adjustment can be respectively carried out under conditions of low-speed driving and high-speed driving, so that the aims of reducing wind resistance and reducing oil consumption are realized; and when the tail fin is hoisted to a vertical state, the novel self-adapted car tail fin can also has the effect of an auxiliary brake.

Description

A kind of NEW ADAPTIVE automobile tail fin

Technical field

The utility model relates to a kind of automobile tail fin, relates in particular to a kind of NEW ADAPTIVE automobile tail fin.

Background technology

Automobile tail fin also can carry out rectification to the vehicle body air-flow under the vehicle high-speed condition except having ornamental effect, reduce windage to reach the purpose that reduces oil consumption.But the effect of rectification is only obvious when car speed is higher, not only can't play under the low speed the effect of rectification, thereby causes certain resistance to increase oil consumption to vehicle body on the contrary.Existing automobile tail fin mostly is and is fixed on vehicle body, can't automatically regulate according to speed, so automobile tail fin has larger room for improvement.

The utility model content

In order to solve the existing weak point of above-mentioned technology, the utility model provides a kind of NEW ADAPTIVE automobile tail fin.

In order to solve above technical matters, the technical solution adopted in the utility model is: a kind of NEW ADAPTIVE automobile tail fin, comprise automobile tail fin, and automobile tail fin and triangle regulating plate are fixed; The triangle regulating plate is connected with main hydraulically extensible support, secondary hydraulically extensible support respectively by stub axle, secondary bearing pin.

Main hydraulically extensible support, secondary hydraulically extensible support all are connected with sensor by signal wire (SW).

The utility model can be respectively in the situation that low speed and run at high speed and carry out adaptivity and regulate, thereby reach the purpose that reduces windage, reduces oil consumption; When the empennage rise reaches vertical state, can play again the effect of assist brake.

Description of drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the configuration state figure of the utility model under low vehicle speeds.

Fig. 3 is the configuration state figure of the utility model when braking under high vehicle speeds.

In figure: 1, sensor; 2, signal wire (SW); 3, main hydraulically extensible support; 4, stub axle; 5, triangle regulating plate; 6, automobile tail fin; 7, secondary bearing pin; 8, secondary hydraulically extensible support.

The specific embodiment

The utility model comprises sensor 1, signal wire (SW) 2, main hydraulically extensible support 3, stub axle 4, triangle regulating plate 5, automobile tail fin 6, secondary bearing pin 7 and secondary hydraulically extensible support 8.

Automobile tail fin 6 is fixing with triangle regulating plate 5, and triangle regulating plate 5 is connected with main hydraulically extensible support 3, secondary hydraulically extensible support 8 respectively by stub axle 4, secondary bearing pin 7.Main hydraulically extensible support 3, secondary hydraulically extensible support 8 are connected with sensor 1 by signal wire (SW) 2, and accept the signal from sensor 1.

Adopt technique scheme, the effect that the utility model patent obtains is:

(1) vehicle is under low-speed conditions, and main hydraulically extensible support, secondary hydraulically extensible support are retracted to extreme lower position, and this moment, the position of automobile tail fin also dropped to minimumly, reducing the windage under low-speed conditions, thereby reduced oil consumption;

(2) vehicle (as speed greater than 80KM/H) under high-speed condition, speed sensor passes to main hydraulically extensible support, secondary hydraulically extensible support with signal by signal wire (SW), after main hydraulically extensible support, the elongation of secondary hydraulically extensible support, automobile tail fin is risen, the air-flow that flows through auto body is carried out rectification, thereby the reduction windage reduces oil consumption;

(3) vehicle is when high-speed condition (promptly) brakes, and secondary hydraulically extensible support further extends, and makes whole automobile tail fin reach vertical state, plays the effect of assist brake.

Empennage can be realized packing up under the adjusting of sensor, normal extension, three states of deceleration.

Above-mentioned embodiment is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in the technical solution of the utility model scope, remodeling, interpolation or replacement also all belong to protection domain of the present utility model.

Claims

1. a NEW ADAPTIVE automobile tail fin, comprise automobile tail fin, it is characterized in that: described automobile tail fin and triangle regulating plate are fixed; Described triangle regulating plate is connected with main hydraulically extensible support, secondary hydraulically extensible support respectively by stub axle, secondary bearing pin.
