1. The working process of the embodiment of the present invention is as follows:

(1). Use the parking brake handle to safely and quickly implement the emergency braking of a car whose driving speed exceeds 60Km/h:

When the driver wants to step on the brake pedal in an emergency, he accidentally stepped on the accelerator pedal. At this time, the car not only slows down but accelerates. In this case, don’t step on the brake pedal. At this time, use your foot to step on the brake pedal, you may step on the accelerator pedal again, you should quickly retract the foot, and then quickly operate the parking brake handle by hand, at the position where the brake is applied until it is released Repeat two or three small arcs of repetitive motion between the braking positions, or when you feel that the car has a deceleration feature (for cars equipped with ABS), just stop the parking brake handle at the position where the brake is applied. The car can stop quickly, the total time from the beginning of wanting to apply the brake to the stop of the car's brake, and the time to press the brake pedal with the foot to apply the emergency brake to the car to stop the car's brake will not 1 second difference;

The above working process is like this: when the parking brake handle 1 is pulled up for the first time, one end of the frequency detection system driving lever 1.4 is also brought up under the magnetic force of the permanent magnet 1.1, and the frequency detection system driving lever 1.4 At the other end, through the piston connecting rod 2.4, the piston and the piston rod 2.1 are pressed down to pressurize the operating frequency detection system sub-cylinder 3. When the piston limit nut 2.3 collides with the cylinder block of the operating frequency detection system master cylinder 2, this is explained. One stroke, the operation frequency detection system main cylinder 2 has already passed 100 ml of gas from the outlet check valve 2.6 through the main sub-cylinder gas connection pipe 2.7 and the air supply port 3.4 to the operation frequency detection system sub-cylinder 3. When the permanent magnet 1.1 will release the frequency detection system drive lever 1.4 (at this time, the parking brake handle 1 can continue to be pulled upwards, which will not damage the hand), under the action of the piston return spring 2.2, the piston and the piston The rod 2.1, the piston limit nut 2.3, the piston connecting rod 2.4, and the frequency detection system driving lever 1.4 all move in the direction that causes the intake air in the master cylinder 2 of the operating frequency detection system to move into the master cylinder 2 of the operation frequency detection system. After the gas is finished, wait for the next time when the operation frequency detection system sub-cylinder 3 is compressed again. (An operation that performs a braking action like this can be repeated an unlimited number of times without adversely affecting the equipment. Generally, it is only repeated three or four times.) The driver feels that the car is slowing down when operating After being reflected, the parking brake handle can be stopped at the position where the brake is applied;

In the previous process, the operation frequency detection system sub-cylinder 3 works as follows: when the operation frequency detection system master cylinder 2 presses it for the first time with 100 ml of gas, the sub-cylinder piston and the piston rod 3.1 must be directed to the operation frequency detection system The moving and closing contacts controlled by the sub-cylinder move 10 mm in the direction of 3.01, and at the same time, the contact movable rod 3.3 is pushed to move in the same direction by 10 mm. After the gas is pressed again for about 100 seconds in about 0.4 seconds, the theoretical distance of the cylinder piston and piston rod 3.1 and the contact movable rod 3.3 at this time is (up 10 mm-down 4 mm + up 10 Mm = 16 mm), when the operating frequency detection system master cylinder 2 presses it for about 100 seconds after the second press of 100 ml of gas, it divides the cylinder piston and piston rod 3.1 The theoretical distance of the upward movement at this time is (16-4+10=22), but in this embodiment of the present invention, the contact movable lever 3.3 to the operating frequency detection system is the movable closing contact 3.01 The moving distance is only set at 19 mm. The operation frequency detection system master cylinder 2 gives the operation frequency detection system sub-cylinder 3 over-pressurized gas, which will be discharged from the piston height-limiting exhaust hole 3.9, so the parking brake handle 1 can be repeatedly pulled up as many times as possible, without any impact on the safety and effectiveness of the present invention; after the parking brake handle 1 is repeatedly pulled up three times as described above, the contact movable lever 3.3 and the operating frequency detection system are controlled by separate cylinders The moving contact 3.01 is closed (actually, at two and a half times, the moving contact 3.01 is already closed), which means that the moving frequency contact 3.01 closed by the operating frequency detection system is closed; at this time, if The parking brake handle 1 is in the braking position, that is, the movable contact 1.31 controlled by the restrictor valve is closed; at this time, the driving speed of the car also exceeds 6Km/h, which is the movable contact of the speed sensor 4.01 is in a closed state, and the speed sensor is normally closed. The dynamic breaking contact 4.02 is in an open state, so the control current will be from one pole of the battery 9 and the dynamic closing contact 1.31 (current limiting valve) controlled by the current limiting valve The controlled moving contact 1.31 is controlled by the parking brake handle 1. When the parking brake handle 1 reaches the braking position, the moving contact 1.31 controlled by the restrictor valve is closed, when the parking brake When the handle 1 reaches the brake release position, the movable closing contact 1.31 controlled by the restrictor valve is in the off state,), then through the rotating contact 4.01 of the speed sensor, and then by the operating frequency detection system. Contact 3.01, and then through the solenoid coil 5.3 to the other pole of the battery 9, causing the solenoid coil 5.3 to generate a magnetic force, the switch lever 5.1 magnetic direction to the position of the car to implement the brake, electronic emergency within 0.2 seconds The braking system will brake the car. At this time, if the driver thinks not to brake so quickly, he can push the parking brake handle 1 down again and return to the braking position, if he wants to brake a little slower. , But the parking system Move the handle 1 down once and return to the braking position. If you want to brake a little slower, you can also push the parking brake handle 1 down again and return to the braking position. , As if using the foot to operate the brake pedal is as safe and fast, that is to say, this is a car that can be braked by hand;

If you want to operate the electronic emergency braking system to brake the car, you must meet several requirements. The first speed must exceed 6Km/h, and the second must be repeated twice per second before emergency braking begins. The operating frequency of two or more times can be achieved within 1.5 seconds after continuously repeating the braking twice or more, and stopping the parking brake handle to the braking position within 1.5 seconds;

The operating frequency detection system is divided into the cylinder piston and the piston rod 3.1 of the cylinder 3, under the force of the cylinder piston return spring 3.2, if the parking brake handle stops in the state of releasing the brake, it returns every second The downward distance is set to about 9 mm. If the parking brake handle is stopped at the brake position, the downward distance per second is set to about 1 mm.

(2) The working condition of the parking brake for the car when the speed is below 6Km/h or when it is stopped:

Just pull up the parking brake handle 1 and stop at the braking position;

The above working process is this: After the parking brake handle 1 is pulled up, the other end of the parking brake handle presses down the restrictor valve control lever 1.3, resulting in a movable contact 1.31 controlled by the restrictor valve Closed, because the vehicle speed is below 6Km/h, the moving contact 4.01 of the speed sensor is in an open state, the normally closed moving contact 4.02 of the speed sensor is in a closed state, and the control current at this time It will go from one pole of the battery 9, the dynamic closing contact 1.31 controlled by the current limiting valve, then the normally closed closing contact 4.02 through the speed sensor, then the relay coil of the relay 7 and then to the other pole of the battery 9, At this time, after the relay coil is energized, the first normally closed relay break contact 7.3 and the second normally closed relay break contact 7.4 are both disconnected, and then the first normally closed contact 7.1 and the second normally open relay are closed Both contacts 7.2 are closed, so that the control current of the electronic parking brake switch 6 is moved from one pole of the battery 9 through the limit switch to break the contact 6.31, then through the second normally open relay to close the contact 7.2, and then driven by the switch Motor 6.1, then through the first normally open contact 7.1 and then to the other pole of the battery 9, causing the switch drive motor 6.1 to perform a forward rotation, driving the parking brake switch lever 6.2 to the position where the brake is applied (when the parking When the vehicle brake switch control lever 6.2 is driven to the position of the braking area, the electronic parking brake system has already implemented the parking brake for the car), when the parking brake switch control lever 6.2 is forced to implement parking After the brake limit switch 6.3 disconnects the limit switch dynamic breaking contact 6.31, the switch drive motor 6.1 stops rotating, and the parking brake switch control lever 6.2 stops here.

(3). Release the parking brake:

Push the parking brake handle 1 down to the end;

The above working process is like this: when the parking brake handle 1 is pushed down to the end, the other end of the parking brake handle will move upward, and the restrictor valve lever 1.3 will be released to allow the current limit The valve 1.2 fully opens the airway valve it controls (in this state, the cylinder piston and the piston rod 3.1, under the force of the cylinder piston return spring 3.2, the return downward distance per second is about 9 mm), Let the sub-cylinder piston and the piston rod 3.1 return to the end in about two to three seconds under the action of the sub-cylinder return spring 3.2; and make the movable contact 1.31 controlled by the restrictor valve open, resulting in The relay coil of relay 7 is de-energized, causing both the first normally open and closed contact 7.1 and the relay second normally open and closed contact 7.2 to be disconnected, when the first normally open and closed contact 7.1 and the second normally open and closed contact 7.2 After both are disconnected, naturally the relay's first normally closed dynamic break contact 7.3 and the relay's second normally closed dynamic break contact 7.4 will be closed, when the relay's first normally closed dynamic break contact 7.3 and the relay's second normally closed dynamic break contact After all points 7.4 are closed, the switch drive motor 6.1 starts to reverse movement, driving the parking brake switch lever 6.2 to the direction of releasing the parking brake limit switch 6.4 (when the parking brake switch lever 6.2 is turned When driving to the area where the parking brake is released, the electronic parking brake system has released the parking brake for the car). When the parking brake switch lever 6.2 forces the parking brake limit switch 6.4 to be released, After the release of the parking brake limit switch 6.41, the open contact, the switch drive motor 6.1 stops rotating, and the parking brake switch control lever 6.2 stops here. (If the present invention is combined with an electronic parking brake car, the parking brake handle does not need to be provided with a locking mechanism and a ratchet pawl, as long as the operation lever is clamped a little, it is necessary to operate the shake It requires at least 2-3 kg of force; if it is combined with a man-machine parking brake system, the parking brake handle must be equipped with a locking mechanism, electronic parking (Brake switch 6 is not necessary);

The implementation braking frequency detection mechanism may be mechanical, electronic, or a combination of mechanical and electronic, such as a position switch and a delay electronic component and a relay connected and controlled Implement a braking frequency detection mechanism; as long as the driver operates the parking brake handle, from the position where the brake is released to the position where the brake is applied, the operation is repeated twice or more per second Frequency, after running back and forth two or more times (or three or more times), it will send a message to brake the car (it can also be understood to supply power to the relay coil), when the parking brake handle is released After the position of the braking area is more than 1 second or more than 1.5 seconds, it sends another message (a message that does not apply braking to the car. It can also be understood that the relay coil is not powered) and repeats the previous operation. The data record is cleared. From the cleared state, the driver operates the parking brake handle, from the position where the brake is released to the position where the brake is applied, with a frequency of repetitive operation less than 1.5 times back and forth per second, When engaging in a back-and-forth action, the driver is not recognized to operate the parking brake lever. The number of times that the back-and-forth action is the same is (information that the car is not braked)

The implementation of the braking frequency detection mechanism is composed of a chip and a position switch or a photoelectric counter, which is relatively easy to install, the function can be set more accurately, and the price is cheaper;

In order not to be erroneously operated, you can set the number of times the operating handle repeats braking more, such as repeating the braking action four or five times. The more repeated the number of times, the lower the chance of misoperation. It is more appropriate to set the frequency of repeated braking of the operating handle once or twice per second.

The configuration of the present invention in a pneumatic brake car is only about a thousand yuan in cost. As long as the valve controlled by the brake pedal is connected in parallel with a valve controlled by hand, and an anti-misoperation of the present invention is configured The system will do.

The present invention can also specifically set a handle to operate the car to implement the service brake or emergency brake, so that the driver will not be too panicked when the accelerator pedal is stepped wrongly, because the driver thinks that the foot stepped on the wrong pedal, foot You don’t have to step on the brake pedal, you can apply emergency braking to the car by hand, so you don’t panic.

The present invention has been designed with some relatively easy-to-understand views to explain, although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be construed as limiting the present invention Those of ordinary skill in the art can make changes, modifications, replacements, and variations to the above embodiments within the scope of the present invention.
