Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tubular motors, in particular to a tubular motor with a mute structure. BACKGROUND

[0002] Tubular motors are mainly used to provide power drive for devices such as electric window curtains, electric roller shutter doors, electric sunshades, and electric projection screens.

[0003] In order to deal with the vibration and noise problems generated during the operation of the tubular motor, various traditional methods are commonly used in the industry to improve its performance. For example, a thick and heavy metal shell is added outside the motor to isolate sound propagation; a spring suspension system is used to absorb part of the vibration energy; or special materials are used to make parts to reduce noise caused by friction. In addition, some design schemes add a layer of soft gasket between the motor and the mounting base to disperse pressure and buffer impact force. However, these measures can alleviate the effects of vibration and noise to some extent, but often have problems such as high structural complexity, high manufacturing cost, and have not fundamentally solved the problem.

[0004] The noise requirement of tubular motors on the market is getting higher and higher, so it is urgent to solve the noise problem of tubular motors when installed on the wall. Although the above-mentioned prior art methods can play a certain role in shock absorption and noise reduction, they still cannot meet the market demand for more efficient, economical and practical solutions. Especially when facing the problem of how to effectively reduce the risk of additional resonance caused by improper assembly, the traditional single or simple combination method is not enough. Therefore, it is urgent to develop a new tubular motor shock absorption structure under a new design concept, which can simplify the construction process and control the cost while ensuring good noise reduction effect. SUMMARY
