[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0022] An electromagnetic brake is a device that uses electromagnetic force to achieve braking. By controlling the magnetic force generated by the electromagnet, the brake mechanism is driven or released, thereby stopping or slowing down the mechanical movement.

[0023] Traditional electromagnetic brakes have the following problems during long-term use: the drive plate and armature are prone to accumulate dust during long-term use, which will reduce the friction effect of the drive plate and cause the friction braking effect to decrease; as the friction effect decreases, the heat generated by friction increases, which may cause the internal temperature to be too high, thereby shortening the service life of the device.

[0024] Based on this, an exemplary embodiment of the present application provides an electromagnetic brake that is easy to dissipate heat. The electromagnetic brake includes a heat dissipation component, which is arranged at the lower part of the electromagnetic brake body and includes a fixed seat and multiple groups of heat sinks; the heat sink can absorb the heat generated during braking and discharge the heat. The provision of multiple groups of heat sinks can increase the heat dissipation area and effectively transfer the heat to the external environment, thereby avoiding the accumulation of generated heat inside the electromagnetic brake body and causing overheating; it helps to keep the electromagnetic brake body within a suitable operating temperature range, ensure the operating stability of the electromagnetic brake body and extend the service life of the electromagnetic brake.

[0025] An exemplary embodiment of the present application provides an electromagnetic brake that is convenient for heat dissipation, such as Figure 1 and 2 As shown, the electromagnetic brake includes an electromagnetic brake body 2, a housing 3 and a heat dissipation assembly 1; the housing 3 is open at the top and has a mounting hole for the shaft to pass through on the bottom; the heat dissipation assembly 1 and the electromagnetic brake body 2 are sequentially arranged in the housing 3 from bottom to top. Figure 3As shown, the heat dissipation assembly 1 includes a fixing base 103 and a heat sink 104; the fixing base 103 is arranged at the lower part of the electromagnetic brake body 2 and is fixed to the shell 3 by fasteners 105; the fixing base 103 is preferably made of a material with good thermal conductivity so as to transfer the heat generated by the electromagnetic brake body 2 to the heat sink 104; the heat sink 104 is divided into multiple groups, and the multiple groups of heat sinks 104 are arranged at intervals at the lower part of the fixing base 103; preferably, the multiple groups of heat sinks 104 are arranged at equal intervals along the mounting hole in the center of the fixing base 103 to increase the heat dissipation area and improve the heat dissipation effect; heat dissipation holes 106 are also provided on the circumferential surface of the shell 3 near the heat sink 104, and the heat dissipation holes 106 can accelerate the dissipation of heat and effectively improve the heat dissipation efficiency. The heat sink 104 can absorb the heat generated during the braking process and discharge the heat. Providing multiple groups of heat sinks 104 can increase the heat dissipation area and effectively transfer the heat to the external environment, thereby preventing the generated heat from accumulating inside the electromagnetic brake body 2 and causing overheating; it helps to keep the electromagnetic brake body 2 within a suitable operating temperature range, ensure the operating stability of the electromagnetic brake body 2 and extend the service life of the electromagnetic brake.

[0026] like Figure 3 and 4 As shown, the electromagnetic brake body 2 includes a sleeve 202, an adjusting bolt 207, and a brake base 201, a drive plate 203, an armature 205, a spring 206, and a mounting block 204 that are sleeved on the outside of the sleeve 202 and arranged in sequence from bottom to top; an electromagnet 208 is embedded in the brake base 201; the adjusting bolt 207 connects the mounting block 204, the armature 205 and the brake base 201 in sequence from top to bottom.

[0027] In one embodiment, to enhance heat dissipation, the heat dissipation assembly 1 further includes an air inlet and outlet duct 101 embedded in the housing 3 and opening toward the drive plate 203. Preferably, the air inlet and outlet ducts 101 are provided in multiple groups, spaced apart along the circumferential surface of the housing 3. The air inlet and outlet ducts 101 can be connected to an external air circulation device or air intake device to introduce cooling air into the electromagnetic brake body 2, thereby reducing the temperature of the electromagnetic brake body 2.

[0028] In order to prevent impurities from clogging the air inlet and outlet ducts 101, a filter 102 is provided at the air inlet and outlet ducts 101. The filter 102 can prevent impurities or dust from entering the electromagnetic brake body, keep the electromagnetic brake body 2 clean, and ensure the stable operation of the electromagnetic brake.

[0029] The working principle of the electromagnetic brake of the present application, which facilitates heat dissipation, is as follows: when braking is required, the power input line is connected, and the electromagnet 208 generates a magnetic field to attract the armature 205 to move in the direction of the electromagnet 208, so that the armature 205 and the drive plate 203 come into contact, thereby achieving braking; when the power input line is disconnected, the spring 206 contracts and drives the armature 205 away from the drive plate 203, and braking ends. During the braking process, part of the heat generated by friction or the coil can be discharged through the air inlet and outlet ducts 101; the other part can be transferred to the heat sink 104 through the fixing seat 103 and discharged through the mounting holes and heat dissipation holes 106 at the bottom of the housing 3. In this way, the multi-stage heat dissipation method can effectively transfer heat to the external environment, preventing the generated heat from accumulating inside the electromagnetic brake body 2 and causing overheating. It helps to maintain the electromagnetic brake body 2 within a suitable operating temperature range, ensure the operating stability of the electromagnetic brake body 2, and extend the service life of the electromagnetic brake.

In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the article or device comprising the element.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
