The working principle is as follows: the brake power assisting device can realize three action modes, namely active braking, power assisting braking and backup braking, and a part consisting of a screw rod 22, a sliding block 16, a connecting slide rail 20, a mounting sleeve 15, a shaft rod 2, a sleeve rod 8, a first buffer spring 14, a second buffer spring 19, a buffer pad 13 and a main cylinder top 12 can generate integral displacement during the active braking and the power assisting braking, and finally a main cylinder piston of a main cylinder 11 is pushed to complete pressure building. Different from active braking, the boosting braking needs to generate a signal through the relative displacement between the sensor magnetic assembly 17 arranged on the loop bar 8 and the sensor magnetic assembly 17, transmit the signal to a controller, and then perform the boosting process. The backup braking is different from the working process of the active braking and the boosting braking, the shaft lever 2, the loop bar 8, the buffer cushion 13 and the main cylinder top 12 are completely pushed by the force of treading by people in sequence to finally push the piston of the main cylinder 11 to complete pressure building, the return spring 10 cannot be compressed in the process, and the first buffer spring 14 is compressed.
During active braking, the motor 27 only receives an automobile braking signal, when the braking signal is received, the motor 27 works to transmit torque to the central gear 6 through the driving gear 26 and the transition gear 25, trapezoidal threads are machined in the center of the central gear 6, the lead screw 22 is matched with the central gear 6, the rotary motion of the central gear 6 drives the lead screw 22 to do linear motion, the lead screw 22, the connecting slide rail 20 and the mounting sleeve 15 are fastened on the connecting slide rail 20, the connecting slide rail 20 is matched with the guide rod 3 through the slider 16, it is guaranteed that the mounting sleeve 15 can do linear non-rotary motion, the mounting sleeve 15 is pushed by the lead screw 22 to drive the main cylinder top 12 to move forwards, and finally the main cylinder top 12 pushes the piston of the main cylinder 11 to build pressure. The second buffer spring 19 is compressed under the push of the connecting slide rail 20 and can drive the loop bar 8 to move forward, and the loop bar 8 is not in contact with the buffer pad 13. In the normal initiative braking process, when the footboard does not receive the object jamming, lead screw 22 is promoting the whole forward motion of inner structure, second buffer spring 19 is installed between loop bar 8 and lead screw 22, lead screw 22 is because footboard return spring's effect second buffer spring 19 is compressed when promoting forward, the compressive force of second buffer spring 19 promotes loop bar 8 motion on transmitting loop bar 8 again, loop bar 8 drives 2 and the lug 1 motion on the axostylus axostyle 2 at rear portion, finally drives the footboard motion. When the pedal is stuck to the feet of a person in the active braking process, the pedal tends to stop, the lifting lug 1, the shaft rod 2 and the loop bar 8 tend to stop, the main cylinder top 12 continues to move forwards to generate braking force for ensuring that the connecting slide rail 20 continues to drive the main cylinder top 12, the lead screw 22 is required to continue to push forwards, the first buffer spring 14 between the loop bar 8 and the lead screw 22 is greatly compressed, the lifting lug 1 relevant to the pedal movement is ensured to be removed, the shaft rod 2 and other parts except the loop bar 8 still play a role, the enough buffering effect is achieved, the force acting on the feet when the pedal is extruded to the feet of a driver is only the compression force of the first buffer spring 14, and the protection effect is achieved.
When a person steps on the pedal during power-assisted braking, the sensor magnetic component 17 arranged on the loop bar 8 moves along with the loop bar 8, the first buffer spring 14 is compressed, the sensor magnetic component 17 arranged on the side surface of the mounting sleeve 15 detects that relative displacement occurs, the elastic force of the first buffer spring 14 is required to be smaller than that of the return spring 10, namely, when the driver starts to step on the pedal, the loop bar 8 moves firstly, so that the sensor magnetic component 17 can detect whether braking is needed or not, after the driver steps on the pedal, power assistance starts, the process after power assistance starts is the same as the working principle of the active braking process, the lead screw 22 pushes the front end part to move integrally, finally, the piston of the main cylinder 11 is compressed under the action of the main cylinder top head 12 to build pressure, but at the moment, different from the active braking process, the loop bar 8 generates displacement forwards, and the first buffer spring 14 is compressed, the positive displacement is detected by the sensor magnetic assembly 17; when the sensor detects that the loop bar 8 generates return stroke, namely the sensor magnetic assembly 17 detects that the positive displacement becomes small, the boosting is finished or the boosting force is kept, and each mechanism returns or keeps at a certain position under the action of the boosting force generated by the return spring 10 or the motor 27 so as to keep certain braking boosting force.
When the power assisting mechanism breaks down and needs backup braking, a driver steps on a pedal and directly drives the loop bar 8 to push the main cylinder top 12 at the front part of the cushion pad 13 through the shaft rod 2, the main cylinder top 12 further pushes the main cylinder 11 to move to complete pressure build, the first buffer spring 14 is compressed in the process, and the pre-pressing amount of the return spring 10 is kept unchanged during installation.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
