[0002] Electromagnetic brakes are mechanical parts that stop or slow down moving parts in machinery, commonly known as brakes or gates. Motor brake plates refer to components or systems used to achieve motor braking in motor control systems. Motor brake plates are important components in electromagnetic brakes and are an important component for controlling brakes. They are used to achieve rapid deceleration, parking or position maintenance during motor operation. However, the motor brake plates currently used in the market have poor heat generation during the braking process, which affects their performance and service life. Summary of the invention

[0003] The utility model aims to solve the shortcomings in the prior art and proposes an air-cooled friction brake plate with high heat dissipation.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high heat dissipation air-cooled friction brake plate, including a brake plate body, the brake plate body is an integrally formed circular ring disk, the inner ring is recessed downward to form an inner ring, and the outer ring forms an outer ring; the inner ring and the bottom surface of the outer ring are a whole; the height of the inner ring is lower than the height of the outer ring.

[0005] Preferably, the inner ring of the brake plate body is provided with a first groove which is radially extending from the center to the outside. A circular groove can also be provided.

[0006] Preferably, three fixing holes are evenly arranged on the outer ring.

[0007] Preferably, the outer ring of the brake plate body is provided with a second groove, and the bottom edge of the second groove is flush with the highest point of the inner ring.

[0008] Preferably, through holes are evenly arranged on the second groove.

[0009] Preferably, there is at least one through hole on the second groove.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model forms an air column during braking through the height difference formed by the inner and outer rings, which can help the heat generated inside the motor to be exchanged with the external environment during operation to achieve heat dissipation. At the same time, the through hole on the second groove can increase the area of ​​heat conduction and improve the heat dissipation efficiency, further improving its performance and extending its service life.

[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution 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, as follows.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The utility model provides a high heat dissipation air-cooled friction brake plate, including a brake plate body 100, the brake plate body 100 is an integrally formed annular disk, the inner ring is concave downward to form an inner ring 200, and the outer ring forms an outer ring 300; the bottom surfaces of the inner ring 200 and the outer ring 300 are integral; the height of the inner ring 200 is lower than the height of the outer ring 300. When the motor brakes, an air column can be formed in the brake plate to help absorb the heat generated during braking, exchange with the external environment, and achieve heat dissipation.

[0019] Better, such as Figure 1 , Figure 4 As shown, the inner ring 200 of the brake plate body 100 is provided with a first groove 201, which is radial from the center to the outside, or a circular groove is provided, which increases the contact area between the brake plate and the air, improves the heat exchange efficiency, and enables faster heat dissipation.

[0020] Better, such as Figure 1 As shown, three fixing holes 400 are evenly arranged on the outer ring 300, so as to ensure that the brake plate matches the motor when installed.

[0021] Better, such as Figure 3As shown, the outer ring of the brake plate body 100 is provided with a second groove 500, and the bottom edge of the second groove 500 is flush with the highest point of the inner ring 200. This ensures that when the motor is braked, the heat generated inside can be smoothly dissipated through the through hole.

[0022] Better, such as Figure 3 As shown, the second groove 500 is evenly provided with at least one through hole 501. The through hole 501 serves as a heat conduction path. When the motor is braked, the heat generated by the braking is discharged outward through the through hole 501, thereby achieving heat dissipation.

[0023] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
