Description
Technical Field
[0001] The utility model belongs to the technical field of brakes, in particular to an automobile electronic mechanical brake. Background Art
[0002] Automotive electromechanical brakes are a new type of braking system that combines electronic control and mechanical braking technologies. They incorporate multiple components, including an electronic control unit, an electric drive unit, and a mechanical actuator. These components work together to control the braking process through electrical signals, replacing the hydraulic pressure required in traditional hydraulic systems.
[0003] Brake pads on automotive mechanical brakes are exposed to the complex outdoor environment for extended periods of time. Outdoor air, moisture, and salt easily cause rust to form on the pads. Traditionally, the solution to rusting brake pads involves intermittently applying the brakes while the car is in motion to remove the rust. However, rusting brake pads degrades braking performance, and applying the brakes while driving poses a significant safety hazard.
[0004] To this end, the utility model provides an automobile electronic mechanical brake. Utility Model Content
[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.
[0006] The technical solution adopted by the present invention to solve its technical problems is: the automobile electronic mechanical brake described in the present invention includes a brake disc, a brake body is provided on the outside of the brake disc, and a brake pad is installed in the brake body; two symmetrically arranged rectangular boxes are fixedly installed in the brake body, an electric push rod is fixedly installed in the rectangular box, a push plate is fixedly installed at the output end of the electric push rod, a liquid storage box made of rubber is fixedly installed in the interior of the rectangular box, and a plurality of spray pipes passing through the rectangular box and aimed at the brake pad are fixedly installed on one side of the liquid storage box, the spray pipes are connected to the interior of the liquid storage box, and a one-way valve is installed inside the spray pipes.
[0007] Furthermore, two symmetrically arranged pressing plates are fixedly mounted on one side of the push plate close to the liquid storage box. The pressing plates are arc-shaped, and a plurality of rollers are rotatably connected to the arc-shaped surfaces of the pressing plates.
[0008] Furthermore, a filter is fixedly installed in one end of the liquid spray pipe away from the liquid storage box.
[0009] Furthermore, an arc-shaped guide plate is fixedly mounted on one end of the liquid spraying pipe close to the filter screen, and a guide hole penetrating the guide plate is provided on the top of the guide plate.
[0010] Furthermore, a collar is fixedly mounted on the output end of the electric push rod, two symmetrically arranged arc-shaped abutment plates are fixedly mounted on the surface of the collar, two rectangular plates are fixedly mounted inside the rectangular plate, an elastic block made of rubber material is fixedly mounted on one side of the rectangular plate, an injection pipe connected to the interior is fixedly mounted on one side of the elastic block, and the end of the injection pipe away from the elastic block is connected to the liquid spray pipe.
[0011] Furthermore, a protective ring is fixedly installed between the electric push rod and the collar, and the protective ring covers the output end of the electric push rod. The protective ring is composed of a plurality of hollow cylinders that are slidably connected.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. The present invention discloses an automotive electronic mechanical brake. The electric push rod within a rectangular box is activated. The push rod, along with a push plate, two curved pressure plates, and several rollers, moves toward the liquid reservoir to squeeze out liquid. This allows the rust remover within the reservoir to be released through a spray pipe and onto the brake pads. The curved pressure plate and the rollers are designed to better protect the reservoir. When the reservoir is squeezed to its maximum extent, one end of the curved pressure plate contacts the inner wall of the rectangular box. This allows for a gap between the pressure plate and the inner wall of the rectangular box to deform, effectively preventing the reservoir from being squeezed and ruptured. Once the rust remover enters the spray pipe, it is sprayed out through a filter. A curved guide plate directs the rust remover upward, effectively preventing the top of the brake pad from being covered by the rust remover after it is sprayed downward. Some of the rust remover is sprayed downward through the guide holes in the guide plate, achieving a comprehensive spraying operation and achieving a better rust removal effect. The designed rust removal operation realizes efficient rust removal of the brake pads, effectively removes rust from the brake pads, and eliminates the need to remove rust from the brake pads by braking, which greatly improves the safety of the brake pads when in use.
[0014] 2. The automotive electronic mechanical brake described in this utility model, after the electric push rod quickly squeezes the liquid reservoir, it immediately drives the abutment plate to move toward the elastic block. The abutment plate quickly squeezes the elastic block, allowing the gas inside the elastic block to enter the liquid spray pipe through the air jet pipe. The gas blows the rust remover toward the far end, further assisting the rust remover in spraying onto the brake pad, ensuring a more comprehensive spray. As the base plate continues to squeeze the elastic block, the gas inside the elastic block continues to blow toward the brake pad, thereby drying and cleaning the brake pad and maintaining efficient operation.

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figures 1 to 4 As shown, an automotive electronic mechanical brake described in an embodiment of the present invention includes a brake disc 3, a brake body 1 is provided outside the brake disc 3, and a brake pad 2 is installed in the brake body 1; two symmetrically arranged rectangular boxes 4 are fixedly installed in the brake body 1, an electric push rod 5 is fixedly installed in the rectangular box 4, and a push plate 6 is fixedly installed at the output end of the electric push rod 5, and a rubber liquid storage box 7 is fixedly installed inside the rectangular box 4. Several spray pipes 8 that pass through the rectangular box 4 and are aimed at the brake pad 2 are fixedly installed on one side of the liquid storage box 7. The spray pipes 8 are connected to the inside of the liquid storage box 7, and a one-way valve is installed inside the spray pipe 8.
[0023] Specifically, two symmetrically arranged pressure plates 9 are fixedly mounted on the side of the push plate 6 proximal to the liquid reservoir 7. These pressure plates 9 are curved, and several rollers 10 are rotatably connected to the curved surfaces of the pressure plates 9. A filter screen 11 is fixedly mounted within the end of the liquid spray pipe 8 distal from the liquid reservoir 7. A curved guide plate 12 is fixedly mounted on the end of the liquid spray pipe 8 proximal to the filter screen 11. A guide hole 13 is formed through the top of the guide plate 12.
[0024] During operation, when the brake pads 2 in the brake body 1 are prone to rusting after being unused for a long time, before starting the vehicle, the electric push rod 5 in the rectangular box 4 is first started (it should be noted that the electric push rod 5 here is a micro electric push rod 5 that meets the usage conditions in this scenario). The electric push rod 5 is used to move the push plate 6, two curved pressure plates 9 and several rollers 10 toward the liquid reservoir 7. The pressure plate 9 and the push plate 6 are used to squeeze the liquid out of the liquid reservoir 7, so that the rust remover in the liquid reservoir 7 is sprayed through the liquid spray pipe 8 to the brake pads 2. The pressure plate 9 is designed to be curved and equipped with several rollers 10 to better protect the liquid reservoir 7. When the liquid reservoir 7 is squeezed to the maximum limit, one end of the curved pressure plate 9 will contact the inner wall of the rectangular box 4. At this time, there is still a gap between the pressure plate 9 and the inner wall of the rectangular box 4 for the liquid reservoir 7 to deform, effectively preventing the liquid from being squeezed and ruptured.
[0025] After the rust remover enters the spray pipe 8, it is sprayed out through the filter 11. The curved guide plate 12 guides the rust remover upward, effectively preventing the rust remover from spraying downward, which would make it difficult for the rust remover to cover the top of the brake pad 2. In addition, some of the rust remover is sprayed downward through the guide holes 13 on the guide plate 12, achieving a full-range spraying operation and achieving a better rust removal effect.
[0026] The rust removal operation designed above can achieve efficient rust removal of the brake pad 2, effectively remove the rust from the brake pad 2, and eliminate the need to remove the rust from the brake pad 2 by braking, thereby greatly improving the safety of the brake pad 2 when in use.
[0027] The output end of the electric push rod 5 is fixedly installed with a collar 14, and two symmetrically arranged arc-shaped abutment plates 15 are fixedly installed on the surface of the collar 14. Two rectangular plates 16 are fixedly installed in the rectangular box 4. A rubber elastic block 17 is fixedly installed on one side of the rectangular plate 16. An air jet 18 connected to the inside is fixedly installed on one side of the elastic block 17. The end of the air jet 18 away from the elastic block 17 is connected to the liquid spray pipe 8. A protective ring 19 is fixedly installed between the electric push rod 5 and the collar 14. The protective ring 19 covers the output end of the electric push rod 5. The protective ring 19 is composed of several hollow cylinders connected in a sliding manner.
[0028] During operation, after the electric push rod 5 quickly completes the squeezing of the liquid storage box 7, it immediately drives the plate 15 to move toward the elastic block 17, and uses the plate 15 to quickly squeeze the elastic block 17, so that the gas in the elastic block 17 enters the liquid spray pipe 8 through the air jet pipe 18 (it should be noted that although the liquid spray pipe 8 is equipped with a one-way valve, the position where the air jet pipe 18 is connected to the liquid spray pipe 8 is at the front end of the one-way valve, which means that the air jet pipe 18 is closer to the filter 11 than the one-way valve). The gas is used to blow the rust remover to the far end, thereby further assisting the rust remover to be sprayed onto the brake pad 2, making the spraying more comprehensive. As the bottom plate continues to squeeze the elastic block 17, the gas in the elastic block 17 will continue to blow toward the brake pad 2, thereby drying and cleaning the brake pad 2, so that it maintains efficient operation.
[0029] Working Principle: When the brake pad 2 in the brake body 1 is prone to rusting after long periods of disuse, before starting the vehicle, the electric push rod 5 in the rectangular box 4 is activated. The push rod 5, along with the push plate 6, two curved pressure plates 9, and several rollers 10, moves toward the liquid reservoir 7. The pressure plates 9 and push plates 6 squeeze the liquid out of the liquid reservoir 7, allowing the rust remover in the liquid reservoir 7 to pass through the spray pipe 8 toward the brake pad 2. Once the rust remover enters the spray pipe 8, it is sprayed out through the filter 11. The curved guide plate 12 guides the rust remover upward, effectively preventing the rust remover from spraying downward, making it difficult for the top of the brake pad 2 to be covered by the rust remover.
[0030] When the electric push rod 5 quickly completes the squeezing of the liquid storage box 7, it immediately drives the abutment plate 15 to move toward the elastic block 17, and uses the abutment plate 15 to quickly squeeze the elastic block 17, so that the gas in the elastic block 17 enters the liquid spray pipe 8 through the jet pipe 18, and uses the gas to blow the rust remover to the far end, thereby further assisting the rust remover to be sprayed onto the brake pad 2, making the spraying more comprehensive.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
