Description
Technical field
Air flow adjustment type car tail spoiler of the present invention, relates to tail spoiler automatic displacement technology after a kind of automobile.
Background technology
When the running car speed of a motor vehicle is higher, the relative vehicle body flow velocity of air is comparatively large, and automobile tail lift is comparatively large, in order to improve stability of automobile, installs spoiler to increase the downforce of the tailstock above the tailstock.But when the speed of a motor vehicle is lower, air is less relative to vehicle body flow velocity, and automobile tail lift is less, does not need excessive downforce.And existing spoiler have cannot according to speed of a motor vehicle automatic position adjusting function and angle, the defect such as air resistance coefficient is large, fuel consumption rate is high.For problem existing in above-mentioned prior art, a kind of novel Air flow adjustment type car tail spoiler of research and design, thus the problem existing for overcoming in prior art is very necessary.
Summary of the invention
In view of problem existing in above-mentioned prior art, the object of the invention is a kind of novel Air flow adjustment type car tail spoiler of research and design.Cannot according to speed of a motor vehicle automatic position adjusting function and angle, the defect such as air resistance coefficient is large, fuel consumption rate is high to overcome that existing spoiler has.
Technical solution of the present invention is achieved in that
Air flow adjustment type car tail spoiler of the present invention, is made up of spoiler and two spoiler supports; It is characterized in that two described spoiler support symmetries are loaded on car trunk both upper ends thereof; Spoiler is cut with scissors by front rod and rear linking rod and is loaded on spoiler support, and spoiler can move forward and backward along spoiler pedestal upper end face under the support of front rod and rear linking rod.
Spoiler support of the present invention comprises two side plates, frame, positive stop, backstop, articulated column I, articulated column II, spring fixed column and two arc latch fitting; Forward and backward on the top of two side plates positive stop and backstop are housed respectively, the middle part of two side plates is forward and backward is equipped with articulated column I and articulated column II respectively, and middle part midway location is equipped with spring fixed column, and two arc latch fitting is housed in the middle of two side plate bottoms.
The upper end thereof of the bottom of spoiler of the present invention and front rod and rear linking rod; Front rod is bending shape bar, and the bending part hinge of front rod is loaded on articulated column I, and locking pin is equipped with in the bottom of front rod, and the bottom of locking pin is against in two arc latch fitting; Rear linking rod is straight shape bar, lower end and articulated column II hinged;
Front rod is positioned at the rear portion of positive stop, and rear linking rod is positioned at the front portion of backstop; Be processed with spring hanging column at the middle part of rear linking rod, between spring hanging column and spring fixed column, tension spring be housed.
Locking pin of the present invention comprises thrust spring and plunger; Thrust spring is packaged in the cotter way of locking pin by plunger; Plunger is curved end with two arc latch fitting contact jaw.
Of the present invention pair of arc latch fitting is lock-bit I and the lock-bit II of the arc that two are connected; Plunger is against the groove of lock-bit I or lock-bit II; The movable drive front rod of spoiler rotates around articulated column I, drives plunger to replace between lock-bit I and lock-bit II kayser simultaneously.
Front rod of the present invention is positioned at the rear portion of positive stop, and rear linking rod is positioned at the front portion of backstop; Positive stop controls the end position that front rod rotates counterclockwise; Backstop controls the end position that rear linking rod rotates clockwise.
Use step:
1, when the speed of a motor vehicle is lower, each parts are in initial position, and both front rod leaned against the rear portion of positive stop; Now the horizontal sextant angle of spoiler is less, and position is more forward; Because spoiler angle is less, and air is less relative to vehicle body flow velocity, and air-flow is less to spoiler component downwards and backward, is not enough to overcome the pulling force of tension spring and the power of locking pin, and each mechanism keeps stable;
2, along with the continuous rising of the speed of a motor vehicle, air-flow increases gradually to spoiler component downwards and backward, makes front-rear linkage have the trend rotated clockwise along articulated column I and articulated column II respectively; When the torque of front-rear linkage is enough to the resistance overcoming tension spring and locking pin lock-bit in two arc latch fitting, front-rear linkage rotates clockwise until rear linking rod contact backstop, simultaneously the plunger of locking pin compresses the vertex that thrust spring crosses two arc latch fitting, is converted to lock-bit II by lock-bit I; Now spoiler horizontal sextant angle is comparatively large, and more rearward, tailstock downforce increases in position, and car body stability improves;
3, when the speed of a motor vehicle reduces gradually, air-flow reduces gradually to spoiler component downwards and backward, makes front-rear linkage have the trend rotated counterclockwise along articulated column I and articulated column II respectively; When the pulling force of tension spring exceedes the resistance of the torque of front-rear linkage and locking pin, front-rear linkage rotates counterclockwise until front rod contact positive stop, simultaneously the plunger of locking pin compresses the vertex that thrust spring crosses two arc latch fitting, lock-bit I is converted to by lock-bit II, now the horizontal sextant angle of spoiler is less, position is more forward, and air resistance coefficient reduces, and fuel consumption rate reduces.
Advantage of the present invention is apparent, is mainly manifested in:
1, the invention solves common spoiler cannot according to speed of a motor vehicle automatic position adjusting function and angle, the defect such as air resistance coefficient is large, fuel consumption rate is high;
2, the present invention can regulate front and back position and the reverse angle of spoiler simultaneously automatically, and alerting ability is high; When the speed of a motor vehicle is lower, the horizontal sextant angle of spoiler is less, and position is more forward, and air resistance coefficient is little, and fuel consumption rate is low; When the speed of a motor vehicle is higher, the horizontal sextant angle of spoiler is comparatively large, and more rearward, car body downforce is large, and car body stability is high in position;
3, of the present invention pair of arc latch fitting designs two lock-bits, thus makes locking pin when low speed and high speed two states, all plays the effect stoping mechanism kinematic; Namely lower in the speed of a motor vehicle, when air-flow is less, spoiler swing can be prevented; Raise gradually when the speed of a motor vehicle until reach speed needed for fast state, after each mechanism is converted to position shown in Fig. 2, if the speed of a motor vehicle slightly declines, the existence of locking pin makes spoiler can not be converted to lower-speed state at once, i.e. each mechanism position shown in Fig. 1;
4, implementation method of the present invention is simple and reliable, i.e. economy but also practical.
The present invention have novel structure, with low cost, safe and reliable, there is the advantages such as good economy, aesthetic property, safety, it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
