Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a sealing mechanism for an aluminum alloy housing of a motor. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The main function of a motor is to use an energized coil to generate a rotating magnetic field and act on the rotor to form a magneto-electrical rotational torque, and use the rotational torque as a power source for electrical appliances or various machines.

[0003] The service life of the motor is affected by the temperature during operation, internal cleanliness, etc. If the motor is poorly sealed and external dust can easily enter the motor, the motor will be easily damaged. The electric door with an arm needs a motor to automatically open and close the door, but since the electric door with an arm is generally installed outdoors, dust and rain can easily damage the motor, causing the electric door to malfunction.

[0004] In order to overcome the above-mentioned defects, prior art 1 (Chinese patent with publication number CN214177028U and application date of 2021-01-12) is a highly sealed motor housing. In the utility model, the sealing cover is clamped to the open end of the outer shell body by the cooperation of the clamping block and the clamping groove, and then secured by the first fastening bolt. The operation is simple, and the sealing cover is convenient for disassembly and assembly, and then the motor body is convenient for taking out and repairing it; a second rubber layer is provided between the sealing cover and the outer shell body, which can improve the sealing between the outer shell body and the sealing cover, and prevent external rainwater and dust from entering the inner part of the outer shell body through the gap between the two, which is not easy to cause damage to the motor body.

[0005] There is also existing patent 2 (a Chinese patent with announcement number CN113872371B and application date of 2021-09-27), a motor shaft end sealing cover that can dissipate heat. The patent has a simple structure and is easy to operate. It can release the seal and dissipate heat when the motor is working, and it can be sealed when the motor is not working to prevent dust from entering the body casing.

[0006] During use, although the sealing of the motor is improved in the prior art 1 and the prior art 2, due to the need for heat dissipation, a small amount of dust will inevitably enter the interior of the motor when the motor dissipates heat, causing damage to the motor body and affecting the service life of the motor.
