Technical Field

[0001] The present invention relates to the technical field of automobile braking, and in particular to an automobile emergency braking system and method. Background Art

[0002] Currently, automobile braking is achieved through wheel braking. The basic principle is that when the vehicle needs to slow down and stop, by stepping on the brake pedal, the car's braking system will generate corresponding braking force to force the wheels to slow down or stop rotating, and rely on the friction generated between the tires and the ground to slow down or stop the car.

[0003] However, when the car's brakes are damaged while it is driving, the car cannot be slowed down and stopped in time, which can easily cause traffic accidents. Summary of the Invention

[0004] The purpose of the present invention is to provide an automobile emergency braking system and method, which solves the problem that when the automobile brakes are damaged during driving, the automobile cannot be slowed down and stopped in time, which easily causes traffic accidents.

[0008] Wherein, the control unit includes a sensor and a switch, the sensor is arranged on the fuel injector, and the switch is connected to the sensor.

[0009] Wherein, the automobile emergency brake system further includes a limit module, which is arranged on the mounting plate and adapted to the fuel injector.

[0010] In which, the limit module includes a limit ring, two limit springs, two groups of limit parts, two pull rods and two limit bolts. The limit ring is fixedly connected to the mounting plate and is located above the mounting plate. The limit ring has two limit cavities, and the fuel injector has two grooves. The two limit parts are respectively adapted to the limit cavities and the grooves. The two ends of each limit spring are respectively fixedly connected to the corresponding limit parts and the limit ring.

When no fuel flows into the automobile, the automobile will not be able to continue driving, thereby achieving the purpose of parking. The sealing gasket in the sealing groove ensures the sealing effect of the fuel injector to prevent fuel leakage. When the automobile brake fails, the fuel injector stops the oil delivery to stop the automobile driving, thereby ensuring the safety of the driver and passengers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The first embodiment is:

[0028] See also Figure 1 and Figure 2 ,in Figure 1 is a schematic diagram of the overall structure of the first embodiment, Figure 1 yes Figure 2 The present invention provides an automobile emergency brake system, comprising a mounting plate 101, a fuel injector 102, and a blocking module. The blocking module comprises a control unit, a blocking plate 103, a sealing ring 104, a slide bar 105, a sliding seat 106, a return spring 107, an extrusion plate 108, a drive motor 109, a disc 110, two limit plates 111, and a friction pad 112. The control unit comprises a sensor 113 and a switch 114.

[0029] According to this specific embodiment, the control unit is connected to the fuel injector 102, the blocking piece 103 is movably connected to the fuel injector 102 and inserted into the fuel injector 102, the fuel injector 102 has a sealing groove 115, the sealing ring 104 is arranged in the sealing groove 115, and is sleeved on the outer wall of the blocking piece 103, the sliding seat 106 is arranged on the mounting plate 101, one end of the sliding rod 105 is fixedly connected to the blocking piece 103 and passes through the sliding seat 106, the extrusion plate 108 is fixedly connected to the other end of the sliding rod 105, the two ends of the return spring 107 are fixedly connected to the extrusion plate 108 and the sliding seat 106 respectively, the driving motor 109 is arranged on the mounting plate 101, the disc 110 is fixedly connected to the output end of the driving motor 109, and is eccentrically arranged with respect to the output end of the driving motor 109. When the brakes fail during driving, the control unit is turned on to drive the drive motor 109 to operate, and the drive motor 109 drives the disc 110 to rotate. Since the disc 110 and the output end of the drive motor 109 are eccentrically arranged, the disc 110 squeezes the extrusion plate 108, and the extrusion plate 108 pushes the slide bar 105 to slide on the sliding seat 106. At this time, the return spring 107 is compressed, and the slide bar 105 pushes the blocking plate 103 to close the fuel injector 102, stopping the continued delivery of fuel. When no fuel flows into the car, the car will not be able to continue driving, thereby achieving the purpose of parking. The sealing gasket in the sealing groove 115 ensures the sealing effect of the fuel injector 102 to prevent fuel leakage, so that when the car brake fails, the fuel injector 102 stops the oil delivery to stop the car driving, ensuring the safety of the driver and passengers.

[0030] Among them, the two limiting plates 111 are fixedly connected to the extrusion plate 108 and are symmetrically arranged on the outer wall of the extrusion plate 108. The friction pad 112 is fixedly connected to the extrusion plate 108 and is located on the outer wall of the extrusion plate 108. The limiting plate 111 is installed on the extrusion plate 108 to limit the disc 110 to squeeze the specified position of the extrusion plate 108. The friction pad 112 can increase the friction force of the contact between the disc 110 and the extrusion plate 108, which can facilitate the extrusion of the extrusion plate 108.

[0031] Secondly, the sensor 113 is set on the fuel injector 102, and the switch 114 is connected to the sensor 113. When the brakes fail during driving, the switch 114 is installed on the main control of the car. When the switch 114 is pressed, the sensor 113 receives a signal.

[0032] When the brakes of the car fail to function while the car is in motion, the switch 114 is installed on the main control of the car. When the switch 114 is pressed, the sensor 113 receives a signal to drive the drive motor 109 to operate. The drive motor 109 drives the disc 110 to rotate. Since the disc 110 and the output end of the drive motor 109 are eccentrically arranged, the disc 110 squeezes the extrusion plate 108, and the extrusion plate 108 pushes the slide bar 105 to slide on the slide seat 106. At this time, the return spring 107 is compressed, and the slide bar 105 pushes the brake The baffle 103 closes the fuel injector 102 and stops the further delivery of fuel. When no fuel flows into the car, the car will not be able to continue driving, thereby achieving the purpose of parking. The sealing gasket in the sealing groove 115 ensures the sealing effect of the fuel injector 102 to prevent fuel leakage; the friction pad 112 can increase the friction between the contact between the disc 110 and the extrusion plate 108, which can facilitate the extrusion of the extrusion plate 108. When the car brake fails, the fuel injector 102 stops the delivery of oil to stop the car from driving, thereby ensuring the safety of the driver and passengers.

[0033] The second embodiment is:

[0034] Based on the first embodiment, please refer to Figure 3 and Figure 4 ,in Figure 3 is a schematic diagram of the overall structure of the second embodiment, Figure 4 This is a cross-sectional view of the internal structure of the limit module of the second embodiment.

When the fuel injector 102 reaches the specified position on the mounting plate 101, the force of the limiting spring 202 pushes the limiting member into the groove 208 of the fuel injector 102, and then the limiting bolt 206 is used to pass through the pull rod 205 and tighten it on the fuel injector 102, so that the fuel injector 102 is installed and fixed on the mounting plate 101. The operation is convenient and quick, and the fuel injector 102 can be easily installed and fixed on the mounting plate 101.

The pull rod 205 pulls the slider 203 to slide in the limiting cavity 207, and at the same time, the slider 203 drives the limiting arc block 204 to move.

[0038] When the fuel injector 102 is installed on the mounting plate 101, the fuel injector 102 is inserted into the limiting ring 201 and the fuel injector 102 is continuously pushed through the mounting plate 101. The fuel injector 102 enters the limiting ring 201 and squeezes the limiting arc block 204. The limiting arc block 204 enters the limiting cavity 207 and drives the slider 203 to squeeze the limiting spring 202. When the fuel injector 102 is installed on the mounting plate After 101 reaches the designated position, the force of the limit spring 202 pushes the limit arc block 204 into the groove 208 of the fuel injector 102, and then the limit bolt 206 is passed through the pull rod 205 and tightened on the fuel injector 102, so that the fuel injector 102 is installed and fixed on the mounting plate 101. The operation is convenient and quick, and the fuel injector 102 can be easily installed and fixed on the mounting plate 101.
