Structure for blocking motor noise

The utility model provides a structure for blocking motor noise, which is composed of a motor, a gear and a fixing support, and a cavity is arranged on the gear; the motor is fixed to the fixing support and arranged in the cavity, and the motor drives the gear through a transmission shaft of the motor. The gear and the fixing support jointly separate a cavity of the gear from the outside, the motor is arranged in a cavity structure of the gear, the outer wall of the cavity reflects sound waves, sound leakage is reduced, namely, the gear and the fixing support are jointly combined to achieve the sound insulation effect, and transmission of noise of the motor is blocked. Tests show that the noise generation amount of the motor noise blocking structure is reduced by 2-3 decibels compared witha common motor. As the motor is arranged in the cavity of the gear, the motor and the gear intersect in appearance space, and the space occupancy rate is reduced. 本实用新型提供了一种阻断马达噪音的结构，由马达、齿轮和固定支架构成，所述齿轮上设有腔体；所述马达固定在所述固定支架上且置于
