Then, when the user steps on the brake pedal 26 around the hinge axis and hopes to brake, the brake pedal 26 drives the brake slide rail 27 to form a rolling conflict with the brake slide rod 28, and one end of the brake slide rod 28 moves along the inner wall of the brake slide rail 27, and pushes the T-shaped slide rod 25 to squeeze the elastic airbag 23 along the length direction of the driving slide groove 22, so that the gas inside the elastic airbag 23 is introduced into the interior of the air guide bin 18 through the air guide pipe 24 for gathering, thereby increasing the air pressure inside the air guide bin 18 and pushing the T-shaped The slide bar 19 moves downward along the length direction of the air guide bin 18, so that the T-shaped slide bar 19 drives the ejection slide rail 20 to push the ejection slider 21 to drive the V-shaped rod 8 to rotate around the hinge axis with the brake bracket 1, and at the same time, the ejection slider 21 moves along the inner wall of the ejection slide rail 20, and the ejection slide rail 20 drives the reset slider 43 to squeeze the reset spring 42 along the length direction of the guide slide bar 41 to produce a contraction deformation, and at the same time, one end of the T-shaped slide bar 19 drives one end of the corrugated sealing tube 45 to pass through the inside of the storage groove 44 and stretch, so that the corrugated sealing tube 45 forms a sealing package on the bottom of the air guide bin 18 to improve the sealing performance of the device; While driving the V-shaped rod 8 to rotate around the hinge axis with the brake bracket 1, one end of the V-shaped rod 8 is in conflict with the inclined surface of the travel sensor 7, and the travel sensor 7 is pushed to move along the length direction of the first slide bar 3, and at the same time, the travel sensor 7 squeezes the brake spring 6 along the length direction of the second slide bar 5 to produce a contraction deformation, and the travel sensor 7 is set to monitor the moving distance of the inclined block 4 in real time, and then transmit the monitoring data to the controller 11, and the controller 11 is combined with the vehicle-mounted central control and the real-time driving speed for analysis to determine whether the user needs to brake lightly to slow down, or brake heavily to slow down quickly.

[0039] The implementation principle of the device and method for realizing electric vehicle braking by wireless transmission in this embodiment is as follows: first, a controller 11 is set to analyze and process the signals transmitted by the travel sensor 7, the conflict sensor 10, and the signal sensor 17; then, when the user steps on the brake pedal 26 around the hinge axis and hopes to brake, the brake pedal 26 drives the brake slide rail 27 to form a rolling conflict with the brake slide rod 28, and one end of the brake slide rod 28 moves along the inner wall of the brake slide rail 27, and pushes the T-shaped slide rod 25 to squeeze the elastic airbag 23 along the length direction of the driving slide groove 22, so that the gas inside the elastic airbag 23 is introduced into the interior of the air guide bin 18 through the air guide pipe 24 for gathering, thereby increasing the air flow of the guide tube 24. The air pressure inside the air bin 18 pushes the T-shaped slide bar 19 to move downward along the length direction of the air guide bin 18, thereby causing the T-shaped slide bar 19 to drive the ejection slide rail 20 to push the ejection slider 21 to drive the V-shaped rod 8 to rotate around the hinge axis with the brake bracket 1, and at the same time, the ejection slider 21 moves along the inner wall of the ejection slide rail 20, and the ejection slide rail 20 drives the reset slider 43 to squeeze the reset spring 42 along the length direction of the guide slide bar 41 to produce a contraction deformation, and at the same time, one end of the T-shaped slide bar 19 drives one end of the corrugated sealing tube 45 to pass through the inside of the storage groove 44 and stretch, so that the corrugated sealing tube 45 forms a sealing package for the bottom of the air guide bin 18 to improve the sealing performance of the device; While driving the V-shaped rod 8 to rotate around the hinge axis with the brake bracket 1, one end of the V-shaped rod 8 is in conflict with the inclined surface of the travel sensor 7, and the travel sensor 7 is pushed to move along the length direction of the first slide bar 3, and at the same time, the travel sensor 7 squeezes the brake spring 6 along the length direction of the second slide bar 5 to produce a contraction deformation, and the travel sensor 7 is set to monitor the moving distance of the inclined surface block 4 in real time, and then transmit the monitoring data to the controller 11, and the controller 11 is combined with the on-board central control and the real-time driving speed for analysis to determine whether the user needs to brake lightly and slow down slowly, or brake heavily and quickly and decelerate, and then according to The analysis result of the controller 11 sends a control signal to the signal sensor 2 17 through the signal sensor 1 12, so that the signal sensor 2 17 controls the brake motor 16 to drive the lifting screw 36 to engage with the lifting slide bar 35, and the lifting slide bar 35 drives the brake wheel 37 to move downward along the length direction of the lifting slide slot 34, and at the same time, the brake rail 27 and the brake bevel 38 form a rolling conflict, thereby pushing the brake bevel 38 to move along the length direction of the third slide bar 14, and squeeze the brake spring 39 to produce a contraction deformation, and at the same time, the brake bevel 38 pushes the third slide bar 14 to push the brake block 15 out of the brake disc and achieve braking; When the user quickly and heavily steps on the brake pedal 26 in an emergency, the ejection slide rail 20 pushes the ejection slider 21 to drive the V-shaped rod 8 to rotate around the hinge shaft to drive the transmission inclined rod 9, and when the transmission inclined rod 9 is driven to form a conflict with the conflict wheel 33, the conflict wheel 33 pushes the U-shaped transmission block 31 to move along the length direction of the transmission slide rod 29, and the U-shaped transmission block 31 squeezes the transmission spring 30 to produce a contraction deformation, and at the same time, the U-shaped transmission block 31 drives the conflict block 32 to form a conflict with the conflict sensor 10, thereby triggering the conflict sensor 10 to send an emergency signal to the controller 11, at which time the controller 11 quickly disconnects the information data transmitted by the travel sensor 7, and collects the current vehicle speed and vehicle body posture information in combination with the on-board central control, and then automatically sends a control signal to the brake motor 16 through the signal sensor 2 17 according to the vehicle information provided by the on-board central control, so as to adjust the conflict travel of the brake block 15 and the brake disc, thereby reducing human misoperation in extreme cases; Then, when the pedaling force on the brake pedal 26 is released, the return spring 42 is relieved of the force and produces a rebound deformation. At the same time, the return spring 42 pushes out the return slider 43 along the length direction of the guide slide bar 41, and the return slider 43 pushes the ejection slide rail 20 to drive the T-shaped slide bar 19 to move inside the air guide bin 18, and the internal gas of the air guide bin 18 is introduced into the elastic air bag 23 through the air guide pipe 24. At the same time, the elastic air bag 23 produces a stretching deformation and pushes out the T-shaped slide bar 25 along the length direction of the driving slide groove 22, so that the T-shaped slide bar 25 pushes the brake slide bar 28 to form a conflict with the brake pedal 26, and pushes the brake pedal 26 to return to its original position around the hinge axis.
