[0036] EMBODIMENT

[0037] Referring to Figure 1 The automobile brake described in the embodiment includes a brake disc 2, a load 11, a vehicle computer 13, a wheel speed sensor 14, and a current sensor 12. The brake disc 2 and the fixed frame 4 are both fixed on the bearing 1.

The A direction is the inner side, and the B direction is the outer side. The brake caliper 3 is sleeved on the surface of the brake disc 2. The brake pad 5 is arranged on both sides of the brake disc 2 and installed in the brake caliper 3. The brake caliper 3 is fixed with the sub-pump 6 on one side of the fixed frame 4. The piston in the sub-pump 6 is fixed with one side of the brake pad 5 in the brake caliper 3, and the other side of the brake pad 5 is fixed with the other side of the brake caliper 3. The brake caliper 3 is fixed with the guide sleeve 8 on one side of the fixed frame 4. The fixed frame 4 is fixed with the guide column 7 away from the brake disc 2. The guide column 7 penetrates the brake caliper 3 and is arranged in the guide sleeve 8, as shown in the figure. Figure 1 The spring 81 is arranged in the guide sleeve 8 and sleeved on the surface of the guide column 7. The guide column 7 is fixed with the sliding block 10 at one end in the guide sleeve 8. The sliding block 10 abuts against one end of the spring 81. The compression switch 9 is fixed and penetrated on the surface of the guide sleeve 8. Figure 3

[0038] Referring to Figure 4 ​As shown, the compression switch 9 has a moving contact 91 and a static contact block 92, the moving contact 91 extends into the guide sleeve 8, and the moving contact 91 and the static contact block 92 are both electrically connected to the load 11 through the wire 15; when the brake caliper 3 moves along the guide column 7 to the inside of the brake disc 2 under the combined force of the oppositely arranged brake pads 5 driven by the sub-pump 6, the moving contact 91 is compressed when the guide sleeve 8 moves, and the moving contact 91 and the static contact block 92 are in contact, thereby connecting the circuit for the load 11.

[0039] As shown in Figure 5 , Figure 6 As shown, the current sensor 12 is used to monitor whether the wire 15 has current passing through, and sends a current signal to the vehicle computer 13; the wheel speed sensor 14 is used to obtain the vehicle speed;

[0040] When the vehicle computer 13 receives the current data, the vehicle speed v1 at the current time k is obtained, and under the condition that the vehicle computer 13 continuously obtains the current signal state, the vehicle computer 13 obtains the vehicle speed v2 at the time k+1, if v2>v1, the vehicle computer 13 generates a prompt information to prompt the driver that the brake caliper 3 fails to reset.

[0041] As shown in Figure 4 The compression switch 9 includes a shell 90, the shell 90 is fixed on the surface of the guide sleeve 8, the opening end of the moving contact 91 is in communication with the guide sleeve 8, the moving contact 91 is arranged in the shell 90, the static contact block 92 is fixed on the top of the shell 90, the wire 15 penetrates the shell 90 and is connected to the power supply of the vehicle, one end of the moving contact 91 arranged in the shell 90 is provided with a compression spring 93 and a compression ring 94, the compression ring 94 is fixed with the moving contact 91, the bottom end of the compression spring 93 abuts against one side of the compression ring 94, the top end of the compression spring 93 abuts against the top of the shell 90, the moving contact 91 includes a ball 95 embedded in the bottom thereof, the ball 95 is in rolling connection with the moving contact 91, the outer side of the ball 95 extends into the guide sleeve 8, and the outer side of the ball 95 is in contact with the edge of the sliding block 10 close to the guide column 7, when the guide sleeve 8 moves in the direction C, the ball 95 also moves in the direction C, the sliding block 10 compresses the ball 95, so that the moving contact 91 is in contact with the static contact block 92, thereby connecting the power supply of the load 11.

[0042] In use, when the driver steps on the brake pedal, the sub-pump 6 drives the piston in the sub-pump 6 to drive the brake pad 5 on the inside of the brake disc 2 to contact the brake disc 2 under the action of the oil pressure, which is the prior art, and the present embodiment only uses it, the brake caliper 3 generates a reaction force under the action of the oil pressure, so that the brake caliper 3 moves to the inside of the brake disc 2, as shown in Figure 1 C direction, the brake pad 5 on the outside of the brake disc 2 is driven by the brake caliper 3 to contact the brake disc 2, and the brake disc 2 is formed under the action of the two brake pads 5, as shown in Figure 2

[0043] ​At this time, the brake caliper 3 drives the guide sleeve 8 to move, and the direction of movement is as follows: Figure 4 As shown in the C direction, the guide sleeve 8 drives the housing 90 to move, causing the ball 95 to contact the slider 10. Under the pressure of the slider 10, the moving contact 91 rises, and the top of the moving contact 91 contacts the stationary contact block 92, connecting the power supply to the load 11. The current sensor 12 detects that there is current flowing through the wire 15 and continuously sends the obtained current signal to the vehicle computer 13. When the vehicle computer 13 receives the current data, it obtains the vehicle speed v1 at the current time k. When the vehicle computer 13 continuously obtains the current signal, it means that the vehicle is in continuous automatic mode and the vehicle brake has not been released. The vehicle computer 13 obtains the vehicle speed v1 at time k+1. The driving speed is v2, and time k+1 is the next time after time k. If v2 > v1, that is, when the car is braking, the speed at time k+1 exceeds the speed at time k. At this time, the car is accelerating and the driver has released the brake. This means that the brake caliper 3 has failed to reset. The brake pad 5 located on the outside of the brake disc 2 is in contact with the brake disc 2, which increases the wear of the brake pad 5 and the driving resistance of the car, and increases the fuel consumption of the car. At this time, the on-board computer 13 generates a prompt message to remind the driver that the brake caliper 3 has failed to reset. The relevant components in the guide sleeve 8 should be inspected in time to detect the fault in time, reduce energy consumption, and improve the service life of the brake pad 5.

[0044] Please see Figure 7 As shown, the vehicle computer 13 includes a receiving module 131, a data processing module 132, a display module 133, and an acquisition module 134. The receiving module 131 continuously receives current signals. When the receiving module 131 receives current data, the acquisition module 134 acquires the vehicle speed v1 at the current time k. While the receiving module 131 continues to receive current signals, it acquires the vehicle speed v2 at time k+1. The data processing module 132 compares and analyzes v2 and v1. If v2 > v1, it generates a prompt message. The display module 133 receives the prompt message and displays it. The display module 133 can be an electronic instrument panel.

[0045] Please see Figure 3 As shown, the guide sleeve 8 is detachably fixed to the brake caliper 3 by threads, which facilitates the installation and replacement of the spring 81 inside the guide sleeve 8.
