Detailed description of the invention
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, as follows to the detailed description of the invention.
The invention provides a kind of anti-intrusion brake treadle mechanism.As shown in Figures 1 and 2, this anti-intrusion brake treadle mechanism comprises brake pedal 11, bracing wire 12 and bracing wire actuating unit 13.Brake pedal 11 is fixed on the floor 14 of vehicle, be connected with the piston rod 16 of vehicle vacuum servo-unit 15 by bracing wire 12, bracing wire actuating unit 13 is connected with brake pedal 11, by bracing wire actuating unit 13, the action of trampling brake pedal 11 is converted into the action of tension bracing wire 12, pressed the piston rod 16 of vacuum booster 15 by tension bracing wire 12, thus reach the object of braking.
Particularly, brake pedal 11 comprises base plate 111, pedal 112 and elastic component (scheming not shown), base plate 111 is fixed on the floor 14 of vehicle, and pedal 112 is articulated on base plate 111 by rotating shaft 113, and pedal 112 113 can be rotated around the shaft under the effect of pedal force and restoring force.Elastic component is located between base plate 111 and pedal 112, and after the application force on pedal 112 disappears, elastic component can promote pedal 112 and reset.In the present embodiment, this elastic component is preferably torsion spring.In addition, in other embodiments of the invention, brake pedal 11 also can not arrange base plate 111 and directly be served as the function of base plate 111 by the floor 14 of vehicle, is appreciated that, in such embodiments, pedal 112 is directly articulated on the floor 14 of vehicle by rotating shaft 113.
Please consult Fig. 2 especially, in the present embodiment, bracing wire actuating unit 13 is the four-bar linkage of the quadrangle of four connecting rod compositions.This four-bar linkage comprises four end to end connecting rods, can mutually rotate between two adjacent connecting rods, and in the present embodiment, the mode realizing can mutually rotating between adjacent links adopts the mode of pivot joint to connect on adjacent connecting rod.This four-bar linkage is fixed between base plate 111 and pedal 112 by the relative summit of two wherein, and bracing wire 12 one end be arranged in below piston rod 16 is fixed on the summit of the side of the close base plate 111 of four-bar linkage and pedal 112 junction.
More specifically, in the present embodiment, anti-intrusion brake treadle mechanism also comprises the first guiding mechanism 171, second guiding mechanism 172 and the 3rd guiding mechanism 173.In front panel 18 below the piston rod 16 that first guiding mechanism 171 is positioned at vacuum booster 15.In order to better the pulling force of bracing wire 12 is converted into the pressing force to piston rod 16, second guiding mechanism 172 is positioned at the free end of piston rod 16, the top that the first guiding mechanism 171 and the second guiding mechanism 172 are fixed to piston rod 16 is walked around in bracing wire 12, makes the bracing wire 12 of piston rod 16 both sides form a bending roughly in " V " font at the second guiding mechanism 172 place.3rd guiding mechanism 173 is between the first guiding mechanism 171 and the second guiding mechanism 172.In 3rd guiding mechanism 173 front panel 18 be all fixed on below piston rod 16 the same as the first guiding mechanism 171.Side near piston rod 16 in front panel 18 is fixed on unlike, the 3rd guiding mechanism 173 with the first guiding mechanism 171, and as far as possible near piston rod 16.First guiding mechanism 171 is fixed on the side near vehicle floor 14 in front panel 18, and as far as possible near the floor 14 of vehicle.Bracing wire 12 is fixed on after walking around the first guiding mechanism 171, second guiding mechanism 172 and the 3rd guiding mechanism 173 in the front panel 18 above piston rod 16.Preferably, bracing wire 12 attachment point be positioned at above piston rod 16 is fixed in front panel 18 also as far as possible near piston rod 16.Above-mentioned laying mode makes the bracing wire 12 below piston rod 16 can near front panel 18, can prevent bracing wire 12 from affecting the inner space of vehicle, also the angle of piston rod 16 liang of side guys 12 can be made little as much as possible simultaneously, and bracing wire 12 can piston rod 16 be moved better.In the present embodiment, the first guiding mechanism 171, second guiding mechanism 172 and the 3rd guiding mechanism 173 are track adjusting wheel.
In the present embodiment, the outside of bracing wire 12 is also arranged with Guy wire guide-tube 19, Guy wire guide-tube 19 is sheathed on the outside of the bracing wire 12 on the downside of piston rod 16, and is respectively formed with the radian corresponding with the wheel rim of the 3rd guiding mechanism 173 and the first guiding mechanism 171 at the position contacted with the 3rd guiding mechanism 173 and the first guiding mechanism 171.
When chaufeur tramples brake pedal 11, the pedal 112 of brake pedal 11 rotates to base plate 111 side, the summit be connected with pedal 112 in compressing four-bar linkage is to the vertex movements be connected with base plate 111, thus moved to the direction away from front panel 18 in the summit be connected with bracing wire 12 in four-bar linkage, thus make bracing wire actuating unit 13 can strain bracing wire 12 in the process.Moving when promoting piston rod 16 after bracing wire 12 under tension, then making brake system.When chaufeur stops trampling brake pedal 11, the pedal 112 of brake pedal 11 returns back to original position under the effect of elastic component, makes bracing wire actuating unit 13 drive bracing wire 12 return, thus piston rod 16 is resetted, and brake system cancels braking.
When front part of vehicle is subject to shock drive vacuum booster 15 and piston rod 16 invades inner space, because the brake pedal 11 of anti-intrusion brake treadle mechanism is positioned on the floor 14 of vehicle, and be connected by bracing wire 12 with between piston rod 16.Therefore, on the one hand, the motion backward of piston rod 16 can not drive brake pedal 11 to move backward, brake pedal 11 is arranged on the less vehicle floor of deformation quantity in collision process 14 on the other hand, decrease the displacement of brake pedal 11 in collision process, thus avoid the impact of brake pedal 11 pairs of chaufeur foots, decrease the damage that the intrusion because of brake pedal 11 causes chaufeur.
In sum, anti-intrusion brake treadle mechanism provided by the present invention, on the vehicle floor that during by brake pedal being installed on vehicle collision, deformation quantity is less, and the intrusion volume of brake pedal in the process that front part of vehicle clashed into can be reduced, thus decrease the damage that the intrusion because of brake pedal causes chaufeur foot.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
