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 auto parts and components field, particularly relate to a kind of brake pedal colliding crumple.
Background technology
As everyone knows, the actuating unit of brake system of car is exactly brake pedal, and under usual state, brake pedal is fixed on body dash board and instrument beam, pedal arm is fixed on pedal support by jointed shaft, can pivot, hinged with 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 servo-unit pushrod movement, by servo-unit pushrod movement, braking force is delivered on each wheel, realizes car retardation or stopping.When automobile generation head-on crash, brake pedal depression firmly makes car stop rapidly by chaufeur usually, but brake pedal can be pushed to chaufeur along with the distortion of front panel, to the impulsive force that one, pin is larger, causes 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 collides.
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 colliding 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, also comprise and pull block, described in pull block and be fixedly mounted on crossbeam, the described block that pulls is connected with pedal support by bearing pin, and described bearing pin is made up of hard brittle material.
Described bearing pin material is plastics.
The described block that pulls is square, and the corner pulling block is provided with pin-and-hole, and on described pedal support, correspondence position is provided with through hole, and described bearing pin loads in pin-and-hole and through hole.
Described pedal support is provided with V-type groove, described in pull block and be arranged on V-type groove position.
Described pulling in the middle part of block is provided with boss, is provided with fixed orifice in the middle part of described boss, described in pull block and be bolted by fixed orifice and be arranged on crossbeam.
Described rotating shaft is connected with pedal support bolt.
Described pedal arm end is provided with pedal.
The invention has the advantages that; because on pedal, attachment point is designed to pull block structure; can not be pulled under certain state of tension; can ensure to stablize use under normal circumstances; the fixed relationship of brake pedal and instrument beam can be changed when impulsive force is larger when collision appears in front deck; attachment point is made to be released into free state; pedal arm rotates around servo-unit push rod jointed shaft by rotating around jointed shaft to become; foot-operated place is away from chaufeur, thus the leg reaching protection chaufeur is not wounded.
Accompanying drawing explanation

Mark in above-mentioned figure is: 1, pedal support, and 11, V-type groove, 12, through hole, 2, pull block, 21, boss, 22, pin-and-hole, 3, rotating shaft, 4, pedal arm, 5, pedal.
Detailed description of the invention
Fig. 1 and Fig. 3 is a kind of structural representation colliding 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 block 2, pulling block 2 is fixedly mounted on crossbeam, pulls block 2 and is connected with pedal support 1 by bearing pin.
Bearing pin material is plastics.Pull block 2 for square, the corner pulling block 2 is provided with pin-and-hole 22, and on pedal support 1, correspondence position is provided with through hole 12, and bearing pin loads in pin-and-hole 22 and through hole 12.Pedal support 1 is provided with V-type groove 11, pulls block 2 and is arranged on V-type groove 11 position.Pull in the middle part of block 2 and be provided with boss 21, in the middle part of boss 21, be provided with fixed orifice, pull block 2 and be bolted by fixed orifice and be arranged on crossbeam.Rotating shaft 3 is connected with pedal support 1 bolt.Pedal arm 4 end is provided with pedal 5.
Pedal support 1, mainly plays the effect of sustain pedal arm 4; Pull block 2 to be bolted on crossbeam by middle fixed orifice, and be injection-moulded on pedal support 1 by four pin-and-holes 22, when being subject to greater impact power, four injection moulding pins are pulled block 2 and pedal support 1 is cut off; Pedal arm 43 rotates around the shaft; Pedal arm 4 near middle is provided with a hinge hole be connected with servo-unit push rod; When implementing braking, foot pedal 5, promotes servo-unit pressure m.
With reference to accompanying drawing 2; pull between block 2 and support 1 and connected by surrounding four pin-and-hole 22 injection mouldings; by injection moulding pin during sufficient force by pedal support 1 with pull block 2 and cut off; pedal support 1 with pull block 2 and be separated; according to the intensity pulling the force design injection moulding pin of block 2 when the impulsive force produced during complete automobile collision and normal use, can meet to make this structure the function that normal brake request can meet again crash protection.
When vehicle generation head-on crash, front deck is to the larger impulsive force of pedal support 1, and pull block 2 and be fixed on crossbeam, pedal support 1 and pull between block 2 and produce relative motion, thus injection moulding pin is ruptured by shearing force, pedal support 1 upper part is moved backward, pulls block 2 to keep 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, thus pedal 5 is avoided to hurt leg.
After adopting such structure; because on pedal, attachment point is designed to pull block 2 structure; can not be pulled under certain state of tension; can ensure to stablize use under normal circumstances; when there is collision in front deck; the fixed relationship of brake pedal and instrument beam can be changed when impulsive force is larger; attachment point is made to be released into free state; pedal arm 4 rotates around servo-unit push rod jointed shaft by rotating around jointed shaft to become; foot-operated place is away from chaufeur, thus the leg reaching protection chaufeur is not wounded.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
