Description

Technical Field

[0001] The invention relates to an anti-lock braking device, and in particular to an inertial vehicle braking anti-lock braking device and method. Background Art

[0002] At present, with the increase in the number of cars, the incidence of traffic accidents has also increased. Therefore, people's demand for car safety is increasing. The braking performance of a car is one of the important factors to ensure car safety. Major traffic accidents are often related to the long braking distance of the car and the side slip during emergency braking.

[0003] At present, the installation and use of ABS is not popular, especially in motorcycles and electric vehicles. Therefore, the current use of ABS still has limitations.

[0004] When ABS is working, when the car slows down, the deceleration sensor converts the received deceleration signal into an electrical signal and transmits it to the electronic control unit ECU. The ECU sends a signal to the brake to control the braking force of the brake so that the wheel is not locked and is in a state of rolling and sliding, ensuring that the adhesion between the wheel and the ground is at the maximum value. It can be seen that the deceleration sensor is the primary condition for ABS to enter the working state. Once the sensitivity of the deceleration sensor is reduced or damaged, it will directly increase the danger of car driving. However, at present, the maintenance cost of ABS is expensive, and it is not convenient to replace the whole set. Summary of the invention

[0005] Purpose of the invention: In view of the defects existing in the prior art, the present invention provides an inertial vehicle anti-lock braking device and method to replace the application of deceleration sensors in conventional ABS braking systems, thereby reducing maintenance costs while ensuring the operation of ABS.

[0006] Technical solution: The inertial vehicle anti-lock braking device of the present invention comprises a battery, an ECU, an anti-lock brake regulator, a brake regulating component and a brake; the anti-lock brake regulator senses the deceleration data of the vehicle and adjusts the braking time interval;

[0007] The brake is applied through the brake adjustment assembly; the ECU is connected to the anti-lock brake regulator;

[0008] The anti-lock brake regulator includes a ground, a conductor pointer, a ball bearing, a light rod, an electromagnet, a weight and a rheostat; the conductor pointer, the ball bearing and the weight are connected by the light rod and are located in the same straight line;

[0009] The ECU controls the working state of the anti-lock brake regulator by changing the resistance of the rheostat.

[0010] The brake adjustment assembly includes a brake pedal switch, a coil, a spring, a pull rod, a hydraulic cylinder and a piston; the spring is located on the pull rod, one end of the pull rod is connected to the piston, and the pull rod drives the piston to move under the gravitational force of the coil.

[0011] The anti-lock regulator also includes a copper sheet and a fixing bolt, and the conductor pointer and the light rod are fixed to the outer ring of the ball bearing through the copper sheet and the fixing bolt, so that when the ball bearing is the center of the circle, the angle between the ground and the light rod is equal to the angle between the contact and the conductor pointer.

[0012] X contacts and Y contacts are arranged on both sides of the anti-lock regulator housing, and a Z contact is arranged at the bottom of the housing, and the Z contact is connected to the ECU.

[0013] The X contact is connected to the positive pole of the battery through a wire, and the Y contact is connected to the coil through the brake pedal switch. The X contact faces the front of the car, and the Y contact faces the rear of the car.

[0014] The inertia vehicle anti-lock braking method of the present invention comprises the following steps:

[0015] (1) When the brake pedal is pressed, the external circuit of the anti-lock regulator controlled by the ECU is turned on, the coil attracts the pull rod to make the hydraulic cylinder drive the brake to work, and the car starts to slow down;

[0016] (2) The heavy object is accelerated forward by inertia, and rotates around the ball bearing together with the light rod and the conductor pointer; when the heavy object contacts the ground, the conductor pointer also rotates until it contacts the contact point. At this time, the external circuit of the anti-lock regulator is disconnected but the internal circuit is connected;

[0017] (3) The electromagnet works, attracting the heavy object in contact with the ground back to its original position, disconnecting the circuit between the X contact and the Y contact, and the coil stops working. The pull rod returns to its original position under the action of the spring, the braking force disappears, and the wheel is released from the brake;

[0018] At this time, the car is decelerating, and the heavy object moves from its original position to the ground. After contacting the ground, the car brakes again, and this cycle is repeated until it stops.

[0019] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0020] (1) The present invention is based on the inertia principle and adopts a modular design, which has high cost performance, high sensitivity and high flexibility.

[0021] (2) The ABS anti-lock braking device of the present invention is applied to low-end cars, motorcycles and electric vehicles, and can maximize the brake efficiency in emergency braking situations, thereby reducing the accident rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 , Figure 2 As shown, the anti-lock brake device of the present invention comprises a battery 8, an ECU, an anti-lock brake regulator 9 and a brake 14; the anti-lock brake regulator 9 is used to accurately sense the deceleration data of the vehicle and adjust the braking time interval. The brake 14 performs braking through a brake adjustment component.

[0027] The shell of the anti-lock regulator 9 is a detachable square box body, which is 12 cm long, 5 cm wide and 10 cm high. Two contacts X and Y are respectively arranged on the front and rear walls of the box body, with the X contact facing the front of the car and the Y contact facing the rear of the car. At the same time, a Z contact is arranged at the bottom of the box body to be connected to the ECU, and the ECU controls the ABS braking time interval through the anti-lock regulator 9 to achieve a better braking effect in different road conditions.

[0028] The X contact and the Y contact outside the anti-lock regulator 9 are connected to the external circuit, and the ECU is connected to the variable resistor through the Z contact. Therefore, the ECU controls the internal working state of the anti-lock regulator by changing the resistance value of the variable resistor connected to the circuit.

[0029] like Figure 3 As shown, the anti-lock regulator 9 includes a ground 1, a conductor pointer 2, a ball bearing 3, a light rod 4, an electromagnet 5 and a rheostat 7. The ground 1, the ball bearing 3, the electromagnet 5 and the rheostat 7 are all fixed to the outer shell of the regulator and connected by wires. The inner ring of the ball bearing 3 is fixed to the shell through the central axis, and the conductor pointer 2 and the light rod 4 are connected by wires. Figure 3 It is fixed on the outer ring of the ball bearing 3 in the manner shown, the conductor pointer 2 and the lightweight rod 4 are symmetrically arranged relative to the outer ring of the bearing and fixed by an arc-shaped copper sheet c, and the upper and lower contact positions are fixed by fixing bolts b, so that when the ball bearing 3 is the center of the circle, the angle between the ground 1 and the lightweight rod 4 is equal to the angle between the contact a and the conductor pointer 2. Therefore, when the weight G at the end of the lightweight rod 4 rotates to contact the ground 1, the conductor pointer 2 also rotates to contact the contact a.

[0030] The conductor pointer, ball bearing and weight G are connected by a light rod with a resistor R1. The conductor pointer, ball spring and weight G are fixed and always in the same straight line. Weight G is a solid iron ball with copper plating on the outer surface, which is conductive and can be attracted by the electromagnet.

[0031] The circuits between the main components of the anti-lock regulator 9 are as follows: Figure 3 The light rod 4 is connected in the manner shown. There is a wire inside the light rod 4, and it is connected to the resistor R1. The wire part is exposed at the fixed part of the arc copper sheet and contacts the arc copper sheet c. The light rod 4 is threadedly engaged with the hole on the iron ball inside the weight G, and the wire at the lower end of the light rod is in contact with the copper plating outside the weight G. Therefore, when the anti-lock regulator is working, the weight G is in contact with the ground, and the conductor pointer is in contact with the contact a, the two circuits inside the anti-lock regulator are both turned on. Circuit 1: X contact-ground-weight G-light rod-conductor pointer-contact aY contact; Circuit 2: X contact-ground-variable resistor-electromagnet-conductor pointer-contact aY contact. In addition, the ECU has a circuit that is separately connected to the external circuit connected to the X contact and the Y contact, which is the external circuit of the anti-lock regulator. The ECU can control the circuit on and off separately.

[0032] The brake adjustment assembly includes a brake pedal switch 10, a coil 11, a spring 12, a pull rod 13, a hydraulic cylinder 17 and a piston 18; wherein the battery 8, the ECU, the anti-lock regulator 9, the brake pedal switch 10, the coil 11 and the safety resistor are connected by wires. The X contact is connected to the positive pole of the battery 8 by a wire, and the Y contact is connected to the coil 11 by a wire through the brake pedal switch 10. The pull rod 13 in the figure is an iron component with a thin end, a thick end and a protruding middle, and the protruding part is used to bear the spring force. The thinner part at one end of the pull rod 13 is connected to the hydraulic cylinder piston 18, which can drive the piston 18 to move; the thicker part at the other end of the pull rod is used to bear the attraction of the coil 11, so that the pull rod drives the piston to move through suction. The hydraulic cylinder 17 is a closed cylinder body, which contains brake fluid 16 and a brake piston 18. When the coil 11 is not energized, under the action of the spring 12, the pull rod is at the far left end, the hydraulic cylinder 17 does not work, and the brake 14 is in a relaxed state; when the coil is energized, an attraction is generated on the pull rod 13, and under the action of the attraction, the pull rod 13 moves to the right, the hydraulic cylinder works, the brake piston 18 compresses the brake fluid 16, and the pressure is transmitted to the brake 14 through the brake fluid 16 in the brake oil pipe 15, and the brake 14 works to press the wheel hub to slow down the car.

[0033] The anti-lock braking method of the inertial ABS anti-lock braking device of the present invention is as follows:

[0034] When the car is running normally, the brake pedal 10 is not depressed and the ABS system does not work.

[0035] When the driver applies emergency brakes, the moment the brake pedal is pressed, the external circuit of the anti-lock regulator 9 controlled by the ECU is turned on, and the entire circuit is also turned on. The coil 11 works, pulling the pull rod 13 to make the hydraulic cylinder 17 work, the brake fluid 16 generates pressure, and the brake 14 works, achieving the braking effect, and the car starts to slow down.

[0036] During the deceleration process of the car, the heavy object G generates forward acceleration due to inertia, and rotates around the ball bearing 3 together with the light rod 4 and the conductor pointer 2. When the heavy object G moves to contact the ground 1, the conductor pointer 2 also rotates to contact the contact a. At this time, the circuit from the X contact to the Y contact is turned on, the electrical signal is transmitted to the ECU, and the external circuit of the anti-lock regulator 9 controlled by the ECU is disconnected. However, the internal circuit of the anti-lock regulator is turned on, so the brake is still working.

[0037] In the circuit of the heavy object G, line 1: "X contact-ground-heavy object G-light rod-conductor pointer-contact aY contact" is connected, and at the same time, another variable resistor and electromagnet circuit in the anti-lock regulator 9 is also connected. The electromagnet works, attracting the heavy object G that is in contact with the ground, so the heavy object G breaks contact with the ground and returns to its original position, the circuit from the X contact to the Y contact is disconnected, and the entire circuit is also disconnected. Therefore, the coil 11 stops working, the pull rod 13 returns to its position under the action of the spring 12, the braking force disappears, and the wheel is released from the brake.

[0038] At this time, the car is still in a deceleration state, and the weight G moves from its original position to the ground. After contacting the ground, the car brakes briefly again. This cycle repeats, and the brake plays the role of "point braking" until the car stops.

[0039] ECU controls the resistance of the variable resistor connected to the circuit, changes the voltage across the electromagnet, changes the electromagnetic force, and changes the movement time of the weight G, which plays a role in changing the time interval of the car's "brake". In this way, the car has a good braking effect under different road conditions.
