Description

Technical Field

[0001] This utility model belongs to the field of vehicle auxiliary braking technology, and specifically relates to a vehicle auxiliary braking system. Background Technology

[0002] The braking system is a series of specialized devices on a car used to apply a certain force from the road surface to the car wheels, thereby forcibly braking the vehicle to a certain extent. The braking system mainly consists of four parts: the power supply device, the control device, the transmission device, and the brakes. The main functions of the braking system are to decelerate or even stop a moving car, maintain a stable speed for a car traveling downhill, and keep a stopped car stationary. The Brake Assist System (BAS) optimizes the vehicle's braking capacity during emergency braking operations. The system detects emergency braking situations by sensing the braking force and magnitude, and then applies the most appropriate pressure to the brakes. This helps reduce braking distance. The Brake Assist System (BAS) assists the Anti-lock Braking System (ABS).

[0003] However, in an emergency, when only the car's braking system between the brake pedal and the brake is used, if there is a problem with the pipe connection or the lower limbs cannot react quickly enough, causing partial failure of the braking system, the driver needs to press the brake pedal deeply to achieve the desired effect, which is difficult to do.

[0004] In summary, the existing technology has problems such as partial connection issues, difficult and inconvenient operation of the braking system, and lack of a replacement braking system for buffering. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a vehicle auxiliary braking system that can solve the problems of existing technologies, such as partial connection problems, laborious and inconvenient braking system operation, and the lack of a replacement braking system for buffering. This utility model provides a vehicle auxiliary braking system, which includes a master cylinder. One side of the master cylinder is connected to the brake pedal, and its bottom is connected to a hydraulic unit via a pipe.

A first resistor and a second resistor are provided between the upper and lower circuits, and a circuit switch is provided between the first resistor and the second resistor. Wheel speed sensors are mounted on all four wheels and are connected to an ABS control unit. The other side of the ABS control unit is connected to the hydraulic unit.

[0008] Optionally, the first braking support member and the second braking assembly are perpendicular to each other.

[0009] Optionally, the first braking clamping member includes a brake drive structure, which is connected to a brake caliper, and the bottom of the brake caliper is provided with a clamping cavity.

[0010] Optionally, the clamping cavity includes a venting groove, an electromagnetic coil on the outside of the venting groove, the clamping cavity being connected to an air pipe on the inside, a telescopic column on the outside of the air pipe, one side of the telescopic column being connected to the inner ring of the electromagnetic coil, and the other side being fixedly connected to a sliding magnetic block, the other side of the sliding magnetic block being fixedly connected to an internal friction block, and the sliding magnetic block being adapted to the upper and lower sliding grooves of the clamping cavity.

[0014] Optionally, a protective sleeve is provided on the outside of the brake caliper and the clamping cavity.

[0015] In summary, this utility model has at least one of the following beneficial effects:

[0016] This invention uses a circuit switch to control the second braking component for braking, which is independent of the original auxiliary braking system. Therefore, even if the original auxiliary braking system malfunctions, braking can still be performed, ensuring the safety of the auxiliary braking system. Braking can be completed simply by operating the circuit switch, which is more convenient and easier to operate than the original method of using the brake pedal.

[0017] This invention uses the ABS control unit to receive speed data from the wheel speed sensors on the four wheels and controls the resistance of the first and second resistors to control the braking situation, avoiding the impact of excessively slow or rapid braking on the wheels and the car.

[0023] The following is in conjunction with the appendix Figure 1-3 This utility model will be described in further detail below.

[0024] Example 1, refer to Figure 1-3In this embodiment, to address the problems of existing technologies where partial connection issues lead to laborious and inconvenient braking system operation and the lack of a replacement braking system for buffering, this utility model discloses a vehicle auxiliary braking system. It includes a master cylinder 1, one side of which is connected to the brake pedal 2, and the bottom is connected to a hydraulic unit 5 via a pipe. The hydraulic unit 5 is connected to a first brake support member 4 mounted on each wheel 3 via pipes. A second brake assembly 9 is also mounted on each wheel 3, and the second brake assemblies 9 on the same side are electrically connected. A first resistor 7 and a second resistor 8 are positioned between the upper and lower circuits, and a circuit switch 6 is located between the first resistor 7 and the second resistor 8. Wheel speed sensors 10 are mounted on all four wheels 3 and are connected to an ABS control unit 11. The other side of the ABS control unit 11 is connected to the hydraulic unit 5. The ABS control unit 11 is connected to the first resistor 7 and the second resistor 8, and the first brake support member 4 and the second brake assembly 9 are perpendicular to each other.

[0025] The master cylinder 1, brake pedal 2, hydraulic unit 5, and first brake support component 4 are designed to ensure the original auxiliary braking system functions correctly. The second brake assembly 9, first resistor 7, second resistor 8, and circuit switch 6 form a second auxiliary braking system. This second system can be used when the original auxiliary braking system malfunctions, and it is simple to operate, requiring only the operation of circuit switch 6. The ABS control unit 11 receives data from the wheel speed sensor 10 and controls the hydraulic unit 5, as well as the first and second resistors 7 and 8 in the circuit, to control the braking time and rate. This prevents excessive braking that could damage the wheels 3 and excessive braking that could affect the braking effect.

[0026] The first braking clamping component 4 includes a brake drive structure 13, which is connected to a brake caliper 12. The brake caliper 12 has a clamping cavity 14 at its bottom, including a vent groove 18. An electromagnetic coil 20 is located outside the vent groove 18. The clamping cavity 14 is connected to an air pipe via its inner side. An external telescopic post 19 is located outside the air pipe. One side of the telescopic post 19 is connected to the inner ring of the electromagnetic coil 20, and the other side is fixedly connected to a sliding magnetic block 17. The other side of the sliding magnetic block 17 is fixedly connected to an inner friction block 15. The sliding magnetic block 17 and the upper and lower sliding grooves 16 of the clamping cavity 14 are adapted to each other. An anti-slip ring 21 is provided on the other side of the inner friction block 15. The opposing surfaces of the sliding magnetic block 17 and the electromagnetic coil 20 have the same pole. The vent groove 18 is connected to the brake drive structure 13 via the brake caliper 12. Protective sleeves are provided on the outer sides of the brake caliper 12 and the clamping cavity 14.

[0027] The brake drive structure 13 is an air pump that delivers air pressure through the brake caliper 12 into the air groove 18 of the clamping cavity 14. The air pipe causes the telescopic column 19 to extend and retract. During the entire process, the electromagnetic coil 20, after being energized, exhibits magnetism. Like poles repel each other, causing the sliding magnetic block 17 to slide more smoothly inward along the slide groove 16. The sliding magnetic block 17 drives the inner friction block 15, which in turn drives the anti-slip ring 21 to brake the wheel 3. The protective sleeve is designed to prevent debris from entering the brake caliper 12 and the clamping cavity 14 and affecting the braking effect. Rubber rings are provided at the intersections of the protective sleeve, the brake caliper 12, and the clamping cavity 14.

[0028] Specific implementation principle: When using this utility model, the original auxiliary braking system will first perform braking operation. When some pipelines malfunction, the effect of the original auxiliary braking system will deteriorate. This is because the wheel speed sensor 10 and the ABS control unit 11 are not connected to pipelines and are not affected by them. When the circuit switch 6 is closed, the circuit is closed and the entire circuit is energized. The wheel speed sensor 10 detects the speed of each wheel 3 and transmits it to the ABS control unit 11. The ABS control unit 11 controls the resistance value of the first resistor 7 and the second resistor 8 connected to the circuit, thereby controlling the braking rate. The larger the resistance connected to the circuit, the slower the braking rate; the smaller the resistance, the faster the braking speed.

[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
