[0002] Electromagnetic brakes, also known as electromechanical brakes or EM brakes, are devices that use electromagnetic force to apply mechanical resistance (friction) to slow down or stop movement. Since the mid-20th century, electromagnetic brakes have been widely used in various fields, especially in the automotive, railway, aviation, shipbuilding, metallurgy and other industries. In particular, lightweight brakes are used in the drive devices of low-speed electric vehicles, elderly scooters, and electric wheelchairs to control the braking of the motor to achieve the parking of the running vehicle.

[0038] The utility model is implemented as follows Figure 1-Figure 5 As shown in, it relates to a light brake, including a brake body, a through-hole structure is arranged in the middle of the brake body, the brake body includes a housing 101 and a coil 102, a clutch plate 103, a brake pad 104 and a bottom plate 105 stacked on one side of the housing 101, a connecting hole 101.1 is arranged on one side of the housing 101 close to the bottom plate 105, the bottom plate 105 includes an annular ring 105.1 and a mounting plate 105.2 arranged on the outer side wall of the annular ring 105.1, the mounting plate 105.2 is provided with a first mounting through-hole corresponding to the connecting hole 101.1, and can be detachably connected to the connecting hole 101.1 after the connecting column 3 passes through the first mounting through-hole, and a through-hole structure is arranged inside. A release column 4 is provided, wherein the release column 4 is arranged in the middle part of the clutch plate 103; an elastic reset member 5 is provided between the clutch plate 103 and the housing 101; and the two pairs of side surfaces of the brake pads 104 are parallel. Furthermore, the utility model changes the structure of the bottom plate 105 so that the bottom plate 105 includes an annular ring 105.1 and a mounting plate 105.2 arranged on the outer side wall of the annular ring 105.1; the mounting plate 105.2 is provided with a first mounting through hole corresponding to the connecting hole 101.1; the existence of the mounting plate 105.2 and the uniform arrangement of weight-reducing through grooves 105.3 on the mounting plate 105.2 reduce the overall weight of the bottom plate 105 and reduce the vibration of the axle. In this embodiment, the elastic reset member 5 can be a spring.

[0039] See also Figure 1-Figure 5In this embodiment, the brake pad 104 is provided with a plurality of through grooves 104.1 on both opposite sides, and the through grooves 104.1 are connected to the outer peripheral wall of the brake pad 104. The brake pad 104 generates powder debris during the friction process by providing a plurality of through grooves 104.1. If these debris adhere to the friction surface between the brake pad 104 and the bottom plate 105, the bottom plate 105 may be scratched, thereby affecting the braking effect. The through grooves 104.1 on the surface of the brake pad 104 can quickly discharge these powder debris and keep the space between the brake pad 104 and the bottom plate 105 clean. Furthermore, the through grooves 104.1 can speed up the air flow, dissipate the heat generated by friction faster, and avoid heat accumulation leading to a decrease in the braking effect.

[0040] In this embodiment, an annular assembly groove 101.2 is provided on one side of the housing 101, and the coil 102 is arranged in the annular assembly groove 101.2.

The through-hole structure includes a limiting through hole arranged in the middle of the clutch plate 103, and the diameter of the column head is larger than the aperture of the limiting through hole. Further When the brake is not applied, the coil 102 is energized to generate a magnetic field so that the column head drives the clutch plate 103 to be adsorbed toward the coil 102, so that the column head compresses the elastic reset member 5, so that the brake pad 104 is away from the bottom plate 105; when braking is needed, the power supply of the coil 102 is connected to the end so that the magnetic field of the coil 102 disappears, and the elastic reset member 5 acts on the housing 101 and the column head of the release column 4, and the release column 4 pushes the clutch plate 103 to drive the brake pad 104 to contact the bottom plate 105, so as to achieve the purpose of braking. Furthermore, the release column 4 is provided with a hollow threaded hole, and the middle part of the handle head 601 is provided with an assembly through hole, and the screw can be threadedly matched with the hollow threaded hole after passing through the assembly through hole.

[0042] In this embodiment, the connecting column 3 includes a threaded column 301 and a limiting sleeve 302 sleeved on the outside of the threaded column 301. A limiting groove 103.1 is provided on the outer peripheral side of the clutch plate 103. The limiting sleeve 302 is located in the limiting groove 103.1. The existence of the limiting groove 103.1 can reduce the weight of the utility model.

[0043] In this embodiment, a plurality of notched grooves 8 are provided on the outer peripheral side of the clutch plate 103, and a plurality of notched grooves 8 are provided on the outer peripheral side of the housing 101 body. The presence of the notched grooves 8 can reduce the weight of the utility model. Furthermore, compared with the prior art "CN212455276U", the weight of the utility model is reduced from 340g to 193.6g.

[0044] In this embodiment, the diameter of the bottom plate 105 is 73 mm.

[0045] The mounting plate is evenly provided with weight-reducing grooves 105.3, the first mounting holes and the second mounting holes 105.4.

Specifically, the brake handle of the prior art has a through groove on the handle, and is limited by a spring pin fixed on the housing to prevent the handle from being pulled too much during the manual release process, causing the handle to be offset and the internal structure of the brake to be damaged. The handle changes in structure after material reduction, and the pulling process is more laborious. By changing the original spring pin into a component of the rolling part, the resistance during the handle pulling process can be reduced.

[0047] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
