Description

Technical Field

[0001] This invention relates to a new technology that automatically activates an intelligent braking device when an obstacle or hazard appears in front of a vehicle. The emergency brake plate bears the friction braking of the vehicle on the road, and the cam rotates in the opposite direction to counteract the forward rotation of the vehicle's tires. With one rotation of the cam, the vehicle brakes more than 10 times, consuming the vehicle's forward inertia. The area of ​​the emergency brake plate is more than 20 times the contact area of ​​the vehicle's tires, allowing the vehicle to stop after one meter. Background Technology

[0002] When a car brakes suddenly, it uses drum brakes or disc brakes. These brakes control the tire speed and friction with the road surface. Because the tires have a small contact area with the ground, the car may slide for 20 meters before coming to a stop. Summary of the Invention

[0003] This technology involves installing a support column under the car's frame and mounting an emergency brake plate on the support column. When an obstacle or hazard appears 1-5 meters in front of the car, the emergency brake plate automatically activates, shooting towards the road surface and cutting under the car's tires. The car's inertia causes it to press against the emergency brake plate, which then uses the car's weight to rub against the road surface and brake.

[0004] The area of ​​the brake pad is more than 20 times that of the tire's contact area, and the braking distance is more than 20 times shorter than the braking distance when the car tires rub against the road surface.

[0005] The cam mounted on the emergency brake plate rotates once, causing the car to vibrate up and down more than 10 times, which is similar to the car braking more than 10 times, and dissipating the car's inertial impact more than 10 times.

[0006] The car's inertia propels the tires forward, causing them to rotate. This rotation, in turn, causes the cam to rotate in the opposite direction, counteracting the car's inertia and preventing further forward movement. The car stops after one meter.

[0007] The system automatically activates the emergency brake pedal and simultaneously shuts off the accelerator, stopping fuel supply after a 12-second delay, ensuring the safety of both the driver and the vehicle.

[0008] When this emergency braking flat plate device is working, the vehicle's original braking system rests.

[0009] When the car moves forward again, it first starts reversing. As the car reverses, the cam rotates in the opposite direction, causing the emergency brake plate to move forward and gradually move out from under the car tires. When the car reverses and the tires rotate backward, pushing the last cam to rotate in the opposite direction, the last cam activates motor 14, which rotates clockwise. The spring steel plate of power supply 11 is wrapped around the motor shaft, pulling the front end of hook 10 against motor 14, retracting the emergency brake plate. The rear end of hook 10 hooks and supports the emergency brake plate, ensuring that it does not fall off.

[0017] 5. Cam, fixed on the two sides of the middle longitudinal bone, has 10-16 protrusions. When the car tires run over the cam, they drive the cam to rotate in the opposite direction. When the cam rotates once, it causes the car to vibrate up and down more than 10 times and brake more than 10 times, thus consuming the car's inertial impact force.

[0026] 20, Figure 5 This is an ultrasonic anti-collision circuit from Changxue Electronics. The circuit uses an LM1812 transceiver, controlled by a timer circuit II for both transmitting and receiving (LM1812 is used for both transmitting and receiving). The control distance can be adjusted using a Skfl potentiometer, typically 2-3 meters. Timer circuit 1 forms a monostable circuit. When the alarm distance is reached, pin ② of timer circuit 1 receives a low level (equivalent to 1 / 3 Vcc), triggering the monostable circuit, and pin ③ outputs a high level. A power switch is connected before the buzzer circuit. Simultaneously, the LED lights up, the electronic buzzer sounds an alarm, and the power switch is turned on, activating the emergency braking system. The automatic emergency braking device of the platform then operates. This circuit uses a T / R-40 series ultrasonic transmitter / receiver sensor. Figure 6 ,spare.

[0027] This technology is implemented as follows:

[0028] When an obstacle or hazard appears 1-5 meters ahead of the car, the ultrasonic anti-collision system automatically starts motor 14 to rotate in reverse, spring steel plate 11 pops out the front end of the seven-shaped hook, the rear small hook moves backward, and throws 4 emergency brake plates onto the ground, cutting under the tire. The car's inertia pushes the tire forward to rotate and press against the emergency brake plate. The car's inertial impact force pushes the emergency brake plate to rub and brake on the road.

[0029] The car's inertia causes the tires on the brake pads to rotate, which in turn causes the camshaft 5 to rotate in the opposite direction. The forward rotation of the tires and the reverse rotation of the camshafts cancel each other out, preventing the car from moving forward. This is similar to a person running on a treadmill and being unable to move forward.

[0030] As the cam rotates once, the car vibrates up and down more than 10 times and brakes more than 10 times, thus dissipating the car's inertial impact force.

[0031] The contact area of ​​the emergency brake pad is more than 20 times that of the car tires, shortening the emergency braking distance by more than 20 times. The car stops within one meter and comes to a safe and stable stop.

[0032] At the same time, when the car is in danger, the automatic emergency braking power is activated, the accelerator is turned off, and the fuel supply is stopped after a 12-second delay.

[0033] When the car moves forward again, it first starts reversing. As it reverses, the tires rotate backward, pushing the rotating cam to rotate in the opposite direction, causing the emergency brake plate to move forward and exit under the tires. When the car reverses and the tires rotate in the opposite direction, causing the last cam to rotate in the opposite direction, the cam activates motor 14, which rotates clockwise. Spring plate 11, wrapped around the motor shaft, pulls the front end of hook 10 against motor 14, retracting the emergency brake plate. The rear end of hook 10 hooks hooks and supports the emergency brake plate, ensuring it doesn't fall off.

[0034] Start the car and move forward.
