Description
Technical field
Draught regulation formula automobile tail spoiler of the present invention relates to the automatic displacement technology of tail spoiler behind a kind of automobile.
Background technology
When the running car speed of a motor vehicle was higher, the relative vehicle body flow velocity of air was bigger, and automobile tail lift is bigger, in order to improve stability of automobile, the downforce that spoiler increases the tailstock was installed above the tailstock.Yet when the speed of a motor vehicle was low, the relative vehicle body flow velocity of air was less, and automobile tail lift is less, does not need excessive downforce.And existing spoiler have can't be big according to the automatic adjusting position of the speed of a motor vehicle and angle, air resistance coefficient, defective such as fuel consumption rate height.At existing problem in the above-mentioned prior art, a kind of novel draught regulation formula automobile tail spoiler of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the objective of the invention is a kind of novel draught regulation formula automobile tail spoiler of research and design.With overcome existing spoiler have can't be big according to the automatic adjusting position of the speed of a motor vehicle and angle, air resistance coefficient, defective such as fuel consumption rate height.
Technical solution of the present invention is achieved in that
Draught regulation formula automobile tail spoiler of the present invention is made up of spoiler and two spoiler supports; It is characterized in that described two spoiler support symmetries are loaded on automobile boot both upper ends thereof; Spoiler is loaded on the spoiler support by front rod and rear linking rod hinge, and spoiler can move forward and backward along spoiler support upper surface 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 positive stop and the backstop of being equipped with respectively on the top of two side plates, forward and backward articulated column I and the articulated column II of being equipped with respectively in the middle part of two side plates, the middle part midway location is equipped with spring fixed column, and two arc latch fittings are housed in the middle of two side plate bottoms.
The upper end of the bottom of spoiler of the present invention and front rod and rear linking rod is hinged; Front rod is bending shape bar, and the bending part hinge of front rod is loaded on the 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 fittings; Rear linking rod is straight shape bar, and lower end and articulated column II are hinged;
Front rod is positioned at the rear portion of positive stop, and rear linking rod is positioned at the front portion of backstop; Middle part at rear linking rod is processed with spring hanging column, between spring hanging column and spring fixed column tension spring is housed.
Locking pin of the present invention comprises thrust spring and pin head; The pin head is packaged in thrust spring in the cotter way of locking pin; The pin head is curved end with two arc latch fitting contact jaws.
Of the present invention pair of lock-bit I and the lock-bit II that the arc latch fitting is two arcs that are connected; The pin head is against the groove of lock-bit I or lock-bit II; The moving forward and backward of spoiler drives front rod and rotates around the articulated column I, drives the pin head kayser that replaces between lock-bit I and lock-bit II 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; The end position that positive stop control front rod rotates counterclockwise; The end position that backstop control rear linking rod clockwise rotates.
Use step:
1, when the speed of a motor vehicle was low, each parts was in the initial position, and both front rod leaned against the rear portion of positive stop; This moment, the horizontal sextant angle of spoiler was less, and the position is more forward; Because the spoiler angle is less, and the relative vehicle body flow velocity of air is less, air-flow to spoiler downwards and component backward less, be not enough to overcome the power of pulling force and the locking pin of tension spring, it is stable that each mechanism keeps;
2, along with the continuous rising of the speed of a motor vehicle, air-flow to spoiler downwards and component backward increase gradually, make front-rear linkage that the trend that clockwise rotates along articulated column I and articulated column II be arranged respectively; When the torque of front-rear linkage is enough to overcome the resistance of tension spring and locking pin lock-bit in two arc latch fittings, front-rear linkage clockwise rotates until rear linking rod contact backstop, the pin head of locking pin is compressing the vertex that thrust spring is crossed two arc latch fittings simultaneously, is converted to the lock-bit II by the lock-bit I; This moment, the spoiler horizontal sextant angle was bigger, and after the position was leaned on, tailstock downforce increased, and car body stability improves;
3, when the speed of a motor vehicle reduces gradually, air-flow to spoiler downwards and component backward reduce gradually, make front-rear linkage that the trend that rotates counterclockwise along articulated column I and articulated column II be arranged respectively; When the pulling force of tension spring surpasses the resistance of the torque of front-rear linkage and locking pin, front-rear linkage rotates counterclockwise until front rod contact positive stop, the pin head of locking pin is compressing the vertex that thrust spring is crossed two arc latch fittings simultaneously, be converted to the lock-bit I by the lock-bit II, this moment, the horizontal sextant angle of spoiler was less, the position is more forward, and air resistance coefficient reduces, and fuel consumption rate reduces.
Advantage of the present invention is apparent, mainly shows:
Defectives such as 1, the invention solves common spoiler can't be big according to the automatic adjusting position of the speed of a motor vehicle and angle, air resistance coefficient, fuel consumption rate height;
2, the present invention's front and back position and the reverse angle that can simultaneously regulate spoiler automatically, the alerting ability height; When the speed of a motor vehicle was low, the horizontal sextant angle of spoiler was less, and the position is more forward, and air resistance coefficient is little, and fuel consumption rate is low; When the speed of a motor vehicle was higher, the horizontal sextant angle of spoiler was bigger, and after the position was leaned on, the car body downforce was big, and car body stability is high;
3, two lock-bits of of the present invention pair of arc latch fitting design, thus make locking pin when low speed and two states of high speed, all play the effect that stops mechanism kinematic; Namely lower in the speed of a motor vehicle, air-flow hour can prevent the spoiler swing; When the speed of a motor vehicle raises gradually until reaching the required speed of fast state, after each mechanism was converted to position shown in Figure 2, if the speed of a motor vehicle slightly descends, the existence of locking pin made spoiler can not be converted to lower-speed state at once, i.e. each mechanism position shown in Figure 1;
4, implementation method of the present invention is simple and reliable, and namely economy is practical again.
The present invention have novel structure, with low cost, safe and reliable, have advantages such as good and economic, aesthetic property, safety, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
