[0002] Electromagnetic brakes originated from the application of electromagnetic theory in the 19th century. With the advancement of electrical engineering, electromagnetic braking technology has gradually matured and has been applied to various industrial fields, such as elevators, automobiles, machine tools and automation equipment. Electromagnetic brakes combine electronic control technology to achieve more precise control and higher efficiency. At the same time, they are also developing towards miniaturization and intelligence.

[0003] Electromagnetic brakes are widely used in the field of automobile braking. Generally, the electromagnets are powered by wires to attract brake pads to rub against each other, thereby controlling the speed of the car.

If the brake pads are excessively worn and not replaced in time, it will cause brake failure and endanger driving safety.

[0004] Therefore, it is necessary to develop an electromagnetic automobile brake capable of monitoring the wear of brake pads to solve the above technical problems. Utility Model Content

It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0022] Embodiment 1: An electromagnetic automobile brake, see 1- Figure 6As shown, it includes a brake pad 1, a transmission rod 2, a first mounting plate 3, a second mounting plate 4, a mounting shell 5, an electromagnet 6, a wire 601, a fixing bolt 7, a mounting frame 8, a brake pad 9, an electric slide bar 10 and an elastic member 12. A mounting shell 5 is arranged on the right side of the brake pad 1, and an electromagnet 6 is placed in the mounting shell 5. The wire 601 passes through the mounting shell 5 and is electrically connected to the electromagnet 6. A first mounting plate 3 is arranged on the side of the mounting shell 5 away from the brake pad 1, and a second mounting plate 4 is arranged on the side of the first mounting plate 3 away from the mounting shell 5. The first mounting plate 3, the second mounting plate 4 and the mounting shell 5 are fixed by a plurality of fixing bolts 7. The transmission rod 2 passes through the brake pad 1, the first mounting plate 3, the second mounting plate 4 and the mounting shell 5, and slides inside them. The first mounting plate 3 and the second mounting plate 4 is installed with a dust cover 18, the transmission rod 2 passes through the dust cover 18, the brake pad 1 is sleeved with a mounting frame 8, three electric slide rods 10 are arranged on one side of the brake pad 9, one end of the electric slide rod 10 passes through the mounting frame 8, and the outer side of the electric slide rod 10 is sleeved with an elastic member 12, and also includes a support rod 13, a first sensing contact piece 14, a second sensing contact piece 15 and a guide rod 16, three support rods 13 are arranged on the outer side of the mounting frame 8, the first sensing contact piece 14 is arranged on the support rod 13, and the second sensing contact piece 15 is arranged on the side of the electric slide rod 10 close to the first sensing contact piece 14, and the second sensing contact piece 15 slides and contacts with the first sensing contact piece 14, and a guide rod 16 corresponding to the electric slide rod 10 is fixedly connected to a common side of the mounting frame 8 and the support rod 13, and one end of the guide rod 16 passes through the electric slide rod 10.

[0023] When the device is needed, the user installs the device on the transmission rod 2 of the car, then fixes the brake pad 1 to the wheel hub, the other end of the wire 601 is electrically connected to the car, and the second sensing contact piece 15 is connected to the car's central control. When the user steps on the brake pedal, the wire 601 is energized to start the electromagnet 6, and the electromagnet 6 generates a magnetic field to attract the brake pad 9 to slide and rub against the brake pad 1 to achieve braking of the car. The electric slide rod 10 drives the second sensing contact piece 15 to slide along the guide rod 16. At this time, the first sensing contact piece 14 is not in contact with the second sensing contact piece 15, and the elastic member 12 is stressed. When the user releases the brake, the multiple elastic members 12 return to their original state and drive the brake pads 9 and the electric slide bar 10 to reset. When the brake pads 9 are excessively worn and need to be replaced, the user steps on the brake, and the electric slide bar 10 drives the first sensing contact piece 14 to slide along the guide rod 16. During this process, the first sensing contact piece 14 contacts the second sensing contact piece 15, and the car central control circuit is connected. Subsequently, a signal indicating that the brake pads 9 are excessively worn is transmitted to the car central control to warn the user, thereby achieving the effect of monitoring and early warning of excessive wear of the brake pads 9, eliminating safety hazards such as brake failure to a certain extent, and ensuring driving safety.

[0024] Embodiment 2: Based on Embodiment 1, referring to FIG5 , an electric slider 11 is further included. The electric slider 11 is slidably arranged on the electric slide bar 10 , and an elastic member 12 is connected between the electric slider 11 and the electric slide bar 10 .

[0025] When using the device, the user can control the electric slider 11 to slide on the electric slide rod 10, adjust the distance between the brake pad 9 and the brake pad 1, change the sliding stroke of the brake pad 9, and thus adjust the pressure of the car brake pad 9 on the brake pad 1.

[0026] As shown in FIG. 2 , a hollow heat-conducting shell 17 is also included. The hollow heat-conducting shell 17 is installed on the outside of the mounting shell 5 by bolt connection. The inside of the heat-conducting shell 17 has a hole. The inside of the hollow heat-conducting shell 17 contacts the brake pad 1. The wire 601 passes through the hollow heat-conducting shell 17. The outside of the mounting frame 8 is connected to the hollow heat-conducting shell 17.

[0027] When the user steps on the brake, the friction between the brake pad 9 and the brake pad 1 will generate heat, which will contact the brake pad 1 through the hollow heat-conducting shell 17 and conduct the heat into the hollow heat-conducting shell 17. The hollow heat-conducting shell 17 is welded by two layers of metal shells, and the internal space is vacuum, which reduces heat conduction, prolongs the heat transfer time, and avoids the reduction of the braking coefficient due to the high temperature of the brake pad 9.

[0028] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments may be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
