Abstract
The invention discloses a brake pedal capable of collapsing through collision. The brake pedal comprises a pedal bracket (1), a rotating shaft (3) and a pedal arm (4), and further comprises a pull-off block (2), wherein the pedal arm (4) is connected with the pedal bracket (1) through the rotating shaft (3) and can rotate around the rotating shaft (3); the pull-off block (2) is fixedly mounted on a cross beam and connected with the pedal bracket (1) through a pin shaft made of fragile material. According to the brake pedal, a fixed point on the pedal is designed to adopt the structure of the pull-off block (2), the pin shaft is fractured by stronger impact force generated during collision, and the pull-off block (2) and the pedal bracket (1) are separated, so as to change the move state of an original pedal (5). Therefore, the brake pedal plays an effect of protecting a driver.
Description
Technical field
The invention belongs to the auto parts and components fields, relate in particular to a kind of brake pedal that collides crumple.
Background technology
As everyone knows, the actuating unit of brake system of car is exactly brake pedal, and under state, brake pedal is fixed on body dash board and instrument beam usually, pedal arm is fixed on pedal support by jointed shaft, can pivot, hinged with the servo-unit push rod in the middle of pedal arm, when push down on the pedal or when unclamping pedal, pedal arm rotates around jointed shaft, drive the servo-unit pushrod movement, by the servo-unit pushrod movement, braking force is delivered on each wheel, realize car retardation or stop.When automobile generation head-on crash, chaufeur firmly stops car brake pedal depression usually rapidly, but brake pedal can be pushed to chaufeur along with the distortion of front coaming plate, gives larger impulsive force of pin, causes the chaufeur feet from injuring.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of minimizing makes brake pedal to the brake pedal of the collision crumple of driver because front part of vehicle bumps.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of brake pedal that collides crumple, comprise pedal support, rotating shaft, pedal arm, described pedal arm is connected with pedal support by rotating shaft, and described pedal arm can rotate around the axis, and also comprises pulling piece, and the described piece that pulls is fixedly mounted on crossbeam, the described piece that pulls is connected with pedal support by bearing pin, and described bearing pin is made by hard brittle material.
Described bearing pin material is plastics.
The described piece that pulls is square, and four jiaos that pull piece are provided with pin-and-hole, and on described pedal support, correspondence position is provided with through hole, and described bearing pin is packed in pin-and-hole and through hole.
Described pedal support is provided with the V-type groove, and the described piece that pulls is arranged on V-type groove position.
The described piece middle part of pulling is provided with boss, and described boss middle part is provided with fixed orifice, and the described piece that pulls is bolted by fixed orifice and is arranged on crossbeam.
Described rotating shaft is connected with the pedal support bolt.
Described pedal arm end is provided with pedal.
The invention has the advantages that; because attachment point on pedal is designed to pull block structure; can do not pulled under certain state of tension; can guarantee to stablize under normal circumstances use; when collision appears in front deck in the situation that the larger fixed relationship that can change brake pedal and instrument beam of impulsive force; make attachment point be released into free state; pedal arm rotates by rotating around jointed shaft to become around servo-unit push rod jointed shaft; foot-operated place is away from chaufeur, thereby the shank that reaches the protection chaufeur is not wounded.
Description of drawings
Fig. 1 is a kind of structural representation that collides the brake pedal of crumple of the present invention;
Fig. 2 is that Fig. 1 collides the brake pedal of crumple at the structural representation of the stressed rear decomposition of collision;
Fig. 3 is the structural representation that pulls piece of Fig. 1 brake pedal of colliding crumple;
Mark in above-mentioned figure is: 1, pedal support, 11, the V-type groove, 12, through hole, 2, pull piece, 21, boss, 22, pin-and-hole, 3, rotating shaft, 4, pedal arm, 5, pedal.
The specific embodiment
Fig. 1 and Fig. 3 are a kind of structural representation that collides the brake pedal of crumple of the present invention, comprise pedal support 1, rotating shaft 3, pedal arm 4, pedal arm 4 is connected with pedal support 1 by rotating shaft 3, and pedal arm 4 can 3 rotate around the shaft, also comprise and pull piece 2, pull piece 2 and be fixedly mounted on crossbeam, pull piece 2 and be connected with pedal support 1 by bearing pin.
The bearing pin material is plastics.Pull piece 2 for square, four jiaos that pull piece 2 are provided with pin-and-hole 22, and on pedal support 1, correspondence position is provided with through hole 12, and bearing pin is packed in pin-and-hole 22 and through hole 12.Pedal support 1 is provided with V-type groove 11, pulls piece 2 and is arranged on V-type groove 11 positions.Pull piece 2 middle parts and be provided with boss 21, boss 21 middle parts are provided with fixed orifice, pull piece 2 and are bolted by fixed orifice and are arranged on crossbeam.Rotating shaft 3 is connected with pedal support 1 bolt.Pedal arm 4 ends are provided with pedal 5.
Pedal support 1 mainly plays the effect of sustain pedal arm 4; Pull piece 2 and be bolted on crossbeam by middle fixed orifice, and be injection-moulded on pedal support 1 by four pin-and-holes 22, four injection moulding pins are pulled piece 2 and pedal support 1 is cut off when being subject to greater impact power; Pedal arm 43 rotates around the shaft; Pedal arm 4 near middles are provided with a hinge hole that is connected with the servo-unit push rod; When implementing braking, foot pedal 5 promotes servo-unit decompression braking.
With reference to accompanying drawing 2; pull between piece 2 and support 1 and connect by four pin-and-hole 22 injection mouldings on every side; when being subjected to sufficient force, the injection moulding pin is by pedal support 1 with pull piece 2 and cut off; pedal support 1 with pull piece 2 and separate; pull the intensity of the stressed design injection moulding pin of piece 2 when the impulsive force that produces in the time of can colliding according to car load and normal the use, can satisfy the function of crash protection again so that this structure can satisfy normal brake request.
When vehicle generation head-on crash, front deck is to the larger impulsive force of pedal support 1, be fixed on crossbeam and pull piece 2, pedal support 1 and pull between piece 2 and produce relative motion, thereby make the injection moulding pin be subjected to shearing force and rupture, part motion backward on pedal support 1 pulls piece 2 and keeps former stationary state constant, and pedal 5 keeps motionless or moves towards the direction away from chaufeur due to the effect of the confining force of foot and servo-unit push rod, thereby avoids pedal 5 to hurt shank.
After adopting such structure; because attachment point on pedal is designed to pull piece 2 structures; can do not pulled under certain state of tension; can guarantee to stablize under normal circumstances use; when collision appears in front deck; in the situation that the larger fixed relationship that can change brake pedal and instrument beam of impulsive force; make attachment point be released into free state; pedal arm 4 rotates by rotating around jointed shaft to become around servo-unit push rod jointed shaft; foot-operated place is away from chaufeur, thereby the shank that reaches the protection chaufeur is not wounded.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
