Description

Brake pedal with anti-collision mechanism

Technical Field

The utility model relates to a brake braking technical field especially relates to a take anticollision institution's brake pedal.

Background

In general, the pedal is rigidly fastened to the dash panel and the dash cross member CCB by bolts and coupled to the master cylinder push rod by a cylindrical pin. In performing a braking operation, the driver depresses the pedal, which rotates about the rotational axis and pushes the master cylinder push rod. The working fluid pushes the working cylinder piston under the action of the main cylinder piston to complete the operation action.

When the driver judges that the front end of the vehicle is likely to have an accidental collision, the driver can use great strength to press the brake pedal urgently to stop the vehicle from going forward in order to avoid the accident. If violent collision cannot be avoided, strong energy can be rapidly transmitted to the pedal assembly through the front wall plate of the vehicle body. The pedal assembly is used as a rigid body and can cause serious injury to footsteps and shanks in the process of rapidly invading towards the driver. The existing brake pedal with an anti-collision mechanism can reduce damage, but a switch support is fixedly mounted on the brake pedal, and the switch support limits rotation of a pedal arm of the brake pedal, so that the rotation range of the pedal arm is small, the rotation is limited, and secondary damage to a human body cannot be better reduced.

SUMMERY OF THE UTILITY MODEL

To the deficiency of the prior art, the technical problem to be solved by the present patent application is: how to provide a brake pedal who takes anticollision institution that can make the footboard move to the direction of keeping away from the human body, reduces the secondary injury of collision process.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a brake pedal with an anti-collision mechanism comprises a swing arm, a pedal bracket, a pedal rotating shaft, a collision bracket shaft, a crumple shaft, a left locking bracket, a right locking bracket and a switch bracket; the swing arm is rotatably connected with the pedal rotating shaft, a notch is formed in the pedal bracket corresponding to the pedal rotating shaft, and the pedal rotating shaft penetrates through the mounting holes of the left locking bracket and the right locking bracket and then is fixed in the notch in the pedal bracket; the collision support, the left locking support and the right locking support are riveted through a first rivet and a second rivet respectively, a collision support shaft penetrates through mounting holes in the collision support and the switch support and is fixed on the pedal support, the collision support and the switch support are rotatably mounted on the collision support shaft, openings matched with the collision support shaft are formed in the left locking support and the right locking support respectively, and the switch support and the collision support are riveted through a third rivet and a fourth rivet; the pedal support is provided with a step-shaped falling groove, the crumple shaft is installed in the step-shaped falling groove, and the collision support, the left locking support and the right locking support are provided with U-shaped openings matched with the crumple shaft.

Like this, when receiving the collision, the impact force is transmitted to the collision support, and the collision support collides with the automobile body instrument board crossbeam, and the collision support rotates along collision support axle anticlockwise for first rivet and second rivet are cut, and the anticlockwise rotation of collision support drives switch support anticlockwise rotation, leaves enough space for the clockwise rotation of swing arm, can make better the moving to the direction of keeping away from personnel of swing arm, reduces the secondary injury. When the collision support rotates anticlockwise, the crumple shaft is pushed to move along the step-shaped falling groove, so that the locking functions of the left locking support and the right locking support disappear, meanwhile, the collision support pushes the pedal rotating shaft to be pushed out from the notch, the pedal rotating shaft is separated from the pedal support, and the swing arm rotates clockwise. To sum up, when the swing arm clockwise turning, the switch support anticlockwise rotates, and both move to opposite direction, and the motion space is big, reduction personnel's that can be better injury.

Furthermore, the swing arm comprises a pedal arm and a pedal which is rotatably connected with the pedal arm, and the pedal arm is rotatably connected with the pedal rotating shaft.

Furthermore, one end of the switch bracket, which is close to the pedal arm, is bent upwards and extends. Reserve bigger space for the swing arm rotation, better reduction secondary damage.

Furthermore, the falling groove is composed of an opening circular groove at the front end of the pedal bracket and a falling cavity widened at the rear part. The locking can be realized, the movement in collision can be met, and the pedal rotating shaft can be separated from the pedal support through the movement of the collapse shaft in the falling groove.

Further, the pedal bracket is detachably and fixedly arranged on the automobile front wall plate.

Furthermore, the left locking support and the right locking support are provided with bends corresponding to the notches. The pedal rotating shaft can be prevented from being separated from the pedal bracket during misoperation, and the motion reliability is improved.

To sum up, this brake pedal can make the footboard to keeping away from human direction motion, reduces the secondary damage of collision process.
