Title:
NOISE REDUCTION AND SHOCK ABSORPTION STRUCTURE OF TUBULAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/026731
Kind Code:
A1
Abstract:
Disclosed in the present invention is a noise reduction and shock absorption structure of a tubular motor, comprising a motor housing, a motor body, an output support and a first shock absorption assembly. The motor body is arranged in the motor housing, and the front end of the motor body is connected to a transmission shaft. The output support is fixed at the front end of the motor housing, and is matched with an output shaft. The transmission shaft and the output shaft are in transmission connection by means of the first shock absorption assembly. The first shock absorption assembly comprises a first adapter and a second adapter which are rigid, as well as a first buffer sleeve and a second buffer sleeve which are soft. The transmission shaft, the first adapter, the second adapter and the output shaft are successively in key joint. The first buffer sleeve sleeves on the peripheral surface of the transmission shaft. The input end of the first adapter sleeves on the first buffer sleeve. The second buffer sleeve sleeves on the peripheral surface and the end surface of the output end of the first adapter. The second adapter sleeves on the second buffer sleeve, and allows the end part of the output shaft to abut against the end surface of the second buffer sleeve. The present invention achieves better noise reduction and shock absorption effects, thereby improving the quality of tubular motors.
