Composite brake block of tubular motor

The utility model relates to a composite brake block of a tubular motor, which is widely used in tubular motors on rolling doors and windows, and awnings. The utility model is used as a strength member used in the skidding in an electromagnetic brake, and comprises a base board made of metal materials, wherein the surface of the base board is also fixed with integration formed by brake blocks manufactured by different materials. When in use, the surface of the base board is matched with an electromagnetic iron sucking seat which is provided with a braking spring, and the brake blocks made of non-metal resin materials are matched with a brake disc. The composite type brake block has the advantages that the friction coefficient is big; the heat transfer performance is poor; the brake block and the brake disc can not generate the stick fast phenomenon; the separation is easy; the sensitivity of the brake block is raised. Consequently, the integral performances of the tubular motors are raised, and the opening and the closing of the rolling doors and windows, and the awnings are safe and reliable. Because the surface temperature in work is low, the brake disc is not easy to age, and the service life of the brake disc is prolonged.
