Description

Technical Field

[0001] This application relates to the field of brakes, and more particularly to an automotive electromechanical brake. Background Technology

[0002] Automotive electromechanical brakes are the core component of automotive braking systems. Through precise control of the mechanical structure by an electronic control unit, they achieve braking operation on the wheels. They have characteristics such as rapid response and precise control, and are an important guarantee for the safety performance of modern automobiles.

[0003] During vehicle operation, brake pads in electromechanical brakes need to participate in braking at high frequency. However, in existing technologies, brake pads generate a large amount of heat due to continuous friction after prolonged use. High temperatures can cause the performance of brake pad materials to deteriorate, such as fluctuations in the coefficient of friction, resulting in weakened braking effect and increased braking distance, posing a threat to driving safety. At the same time, high temperatures may cause thermal deformation of components such as brake calipers, compromising the stability of the braking system. Furthermore, high-temperature environments significantly shorten the lifespan of brake pads, increasing vehicle maintenance costs and frequency.

[0004] In view of the aforementioned technologies, the inventors believe that the brake pads of electromechanical brakes have the defect of high overall temperature after long-term use. Therefore, they have proposed an automotive electromechanical brake to solve the above problems. Utility Model Content

[0005] To address the issue of high overall temperature of brake pads in electromechanical brakes after prolonged use, this application provides an automotive electromechanical brake.

[0006] The automotive electromechanical brake provided in this application adopts the following technical solution:

[0007] An automotive electromechanical brake includes a brake caliper body, a brake disc housed inside the brake caliper body, and brake pads movably mounted on both sides of the brake disc inside the brake caliper body. Each brake pad has a guide channel inside, and connecting pipes are fixedly installed at both ends of the guide channel near the outside of the brake pad. A cooling device is fixedly installed on the outer surface of the brake caliper body. An inlet pipe is provided at the bottom of the cooling device, and an outlet pipe is provided at the top of the cooling device. A condenser is installed inside the cooling device. A micro pump is installed at one end of the inlet pipe extending to the outside of the cooling device. Connecting components are also provided on the outer surfaces of the inlet pipe and the outlet pipe for connecting the inlet pipe, the outlet pipe, and the connecting pipe to each other.

[0008] Preferably, the connecting assembly includes a movable sleeve, which is movably fitted onto the mating position of the inlet pipe, outlet pipe and connecting pipe on the outer surface, and a sealing gasket is installed on one end of the inlet pipe, outlet pipe and connecting pipe near the mating position.

[0009] Preferably, the cross-section of the guide channel is disc-shaped, and the guide channel is located in the middle of the brake pad.

[0010] Preferably, the inlet pipe, outlet pipe, and connecting pipe have the same outer diameter, one side of the inlet pipe, outlet pipe, and connecting pipe is located inside the movable sleeve, and the inlet pipe, outlet pipe, and connecting pipe are all fitted into the movable sleeve.

[0011] Preferably, the outer diameter of the sealing gasket is smaller than the inner diameter of the openings on both sides of the movable sleeve, and the outer surface of the sealing gasket abuts against the inner wall of the movable sleeve.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] Through the cooperation of the cooling device, guide channel, and connecting components, the coolant flows into the guide channel through the inlet pipe and connecting pipe, absorbs the heat from the brake pads, and then flows back from the outlet pipe, circulating and cooling. The movable sleeve and sealing gasket ensure a tight connection, improve heat dissipation efficiency, reduce brake pad temperature, and ensure braking performance. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses an automotive electromechanical brake. (Refer to...) Figure 1-3An automotive electromechanical brake includes a brake caliper body 1, a brake disc 2 inside the brake caliper body 1, brake pads 3 movably mounted on both sides of the brake disc 2 inside the brake caliper body 1, a guide channel 4 with a disc-shaped cross-section inside each brake pad 3, the guide channel 4 being located in the middle of the brake pad 3, and connecting pipes 5 fixedly mounted at both ends of the guide channel 4 near the outside of the brake pad 3, a cooling device 6 fixedly mounted on the outer surface of the brake caliper body 1, an inlet pipe 7 at the bottom of the cooling device 6, an outlet pipe 8 at the top of the cooling device 6, a condenser 11 installed inside the cooling device 6, a micro pump 12 extending from one end of the inlet pipe 7 to the outside of the cooling device 6, and connecting components on the outer surfaces of the inlet pipe 7 and the outlet pipe 8 for connecting the inlet pipe 7, the outlet pipe 8, and the connecting pipe 5 to each other.

[0020] By activating the micro pump 12, the coolant, after being cooled by the condenser 11 within the refrigeration unit 6, flows out through the inlet pipe 7 and into the guide channel 4 of the brake pad 3. The guide channel 4 has a disc-shaped structure, increasing the contact area between the coolant and the brake pad 3, effectively absorbing the heat generated during braking. The cooled coolant, after absorbing heat, flows back to the refrigeration unit 6 through the outlet pipe 8, where it is cooled again by the condenser 11, forming a circulating heat dissipation system.

[0021] Reference Figure 2 and Figure 3 The connecting assembly includes a movable sleeve 10, which is movably fitted at the mating position on the outer surface of the inlet pipe 7, the outlet pipe 8, and the connecting pipe 5. A sealing gasket 9 is installed on one side of the inlet pipe 7, the outlet pipe 8, and the connecting pipe 5 near the mating position. The outer diameters of the inlet pipe 7, the outlet pipe 8, and the connecting pipe 5 are the same. One side of the inlet pipe 7, the outlet pipe 8, and the connecting pipe 5 is located inside the movable sleeve 10. The inlet pipe 7, the outlet pipe 8, and the connecting pipe 5 are all fitted into the movable sleeve 10. The outer diameter of the sealing gasket 9 is smaller than the inner diameter of the openings on both sides of the movable sleeve 10. The outer surface of the sealing gasket 9 abuts against the inner wall of the movable sleeve 10.

[0022] By connecting the movable sleeve 10 of the connecting component with the sealing gasket 9, the inlet pipe 7, outlet pipe 8 and connecting pipe 5 are sealed together, and the connecting pipe 5 is moved stably along the inside of the movable sleeve 10 while the brake pad 3 is kept moving.

[0023] The implementation principle of an automotive electromechanical brake according to an embodiment of this application is as follows: The micro pump 12 is activated, and the coolant, after being cooled by the condenser 11 within the refrigeration unit 6, flows out through the inlet pipe 7. Through the movable sleeve 10 of the connecting assembly and the sealing gasket 9, a sealed connection is ensured between the inlet pipe 7, the outlet pipe 8, and the connecting pipe 5, allowing the coolant to flow into the guide channel 4 of the brake pad 3. The guide channel 4 has a disc-shaped structure, increasing the contact area between the coolant and the brake pad 3, effectively absorbing the heat generated during braking. The cooled coolant, after absorbing heat, flows back to the refrigeration unit 6 through the outlet pipe 8, where it is cooled again by the condenser 11, forming a circulating heat dissipation process. This process continuously reduces the temperature of the brake pad 3, preventing performance degradation due to high temperatures, ensuring stable braking performance, improving automotive braking safety and reliability, and simultaneously reducing component thermal deformation and maintenance costs.
