Detailed Description

As shown in the figures, the anti-roll-in brake pedal device in this embodiment includes a pedal base 1, a connecting shaft 2 is disposed on the pedal base 1, a long support arm 3 and a pedal arm 4 are rotatably connected to the connecting shaft 2, a pedal 5 is disposed at the bottom end of the pedal arm 4, a sliding slot 31 is axially disposed at the end of the long support arm 3, a limiting slot 311 is disposed at the end of the sliding slot 31, a rotating shaft 6 is mounted at the end of the pedal arm 4, a short support arm 7 is sleeved on the rotating shaft 6, one end of the short support arm 7 is connected to a cylindrical pin 8, a limiting block 9 disposed in the limiting slot 311 is disposed on the cylindrical pin 8, in this embodiment, the limiting block 9 is a waist-shaped block, the limiting block 9 can move into the sliding slot 31 along with the rotation of the cylindrical pin 8, the end of the cylindrical pin 8 is fixedly connected to a rotating arm 10, a spring 11 is connected between the rotating arm 10 and the, and when rotated, can push the rotating arm 10 to rotate.

In the present embodiment, the spring 11 is connected to the rotating arm 10 and the rotating shaft 6 in the following manner: the rotating arm 10 is provided with a hook 13, the hook 13 is provided with an embedded groove 131, the rotating shaft 6 is provided with an annular groove 61, one connecting end of the spring 11 is hooked on the embedded groove 131, and the other connecting end is hooked on the annular groove 61.

In the present embodiment, the trigger 12 is provided in a half moon-like structure and is disposed above the connecting shaft 2.

The working principle of the embodiment is as follows:

when the vehicle is in a normal state, the short support arm 7 and the long support arm 3 are respectively hinged with the pedal arm 4, the spring 11 is in a stretching state and respectively applies restoring force to the rotating shaft 6 connected with the short support arm 7 and the rotating arm 10 connected with the long support arm 3, meanwhile, as the rotating arm 10 is fixedly connected with the cylindrical pin 8, the limiting block 9 on the cylindrical pin 8 is also driven by the rotating arm 10 to tightly abut against the limiting clamping groove wall of the long support arm 7 in the clockwise direction, and in the process, the spring 11 applies clockwise pre-tightening torque along the center of the cylindrical pin 8, so that a stable triangular structure is formed among the short support arm 7, the long support arm 3 and the pedal arm 4, and the normal braking and treading functions of the vehicle are met.

After the vehicle collides, the triggering part 12 collides with the rotating arm 10 and drives the rotating arm 10 to rotate under the impact of the brake pump push rod, the rotating arm 10 rotates and simultaneously drives the cylindrical pin 8 to rotate anticlockwise, and the cylindrical pin 8 drives the limiting block 9 thereon to rotate synchronously. The rotating arm 10 continuously rotates until the pretightening torque direction of the spring 11 is changed under the continuous extrusion of the trigger 12, namely, the stress direction of the spring 11 winds below the center of the cylindrical pin 8, at this time, the rotating arm 10 continuously rotates under the combined action of the thrust and the spring force of the trigger 12, the limiting block 9 synchronously rotates along with the rotation of the rotating arm 10, and the two side straight surfaces of the limiting block 9 gradually approach the two side inner walls of the sliding groove 31. In the rotating process, the spring 11 deflects and compresses along with the rotation of the rotating arm 10, the stretching state is gradually changed into the compressing state, when the limiting block 9 rotates to the state that the axial direction of the limiting block 9 is consistent with the axial direction of the sliding groove, the limiting block 9 slides upwards into the sliding groove 31 under the action of the spring force, at the moment, the cylindrical pin 8 synchronously moves along with the limiting block 9, the short supporting arm 7 deflects along with the cylindrical pin 8 in the clockwise direction, the long supporting arm 3 deflects towards the anticlockwise direction under the driving of the short supporting arm 7, finally, the constraint of the triangular structure formed by the long supporting arm 3, the short supporting arm 7 and the pedal arm 4 is finished, the pedal transmission route is finished, and the impact is successfully unloaded.

To sum up: the utility model discloses with brake pedal power transmission route integration on footboard arm 4, can realize stable geometry, simple structure, and before triggering, power transmission is stable, triggers the back, can effectively break off the energy transmission of footboard arm 4, protects the passenger, the security performance height.
