AI Technical Summary

Technical Problem

The existing connection structure between the motor and the bracket is complex, resulting in high installation costs, low connection reliability and high vibration and noise. In particular, loosening and vibration problems are prone to occur in range hoods.

Method used

An external thread is provided on the outer peripheral wall of the motor, which is connected to the bracket by screw connection. The bracket includes a support body and a connecting arm. The rotation direction of the motor is the pre-tightening screw connection direction. The protrusion and the positioning hole are combined to achieve quick installation and stable connection.

Benefits of technology

The installation process is simplified, material costs and vibration noise are reduced, the connection stability between the motor and the bracket is improved, and loosening and vibration noise problems are avoided.

Abstract

The invention relates to a motor mounting structure which comprises a motor and a support, external threads are arranged on the peripheral wall of the motor, the support is fixedly arranged on the peripheral wall of the motor in a sleeving mode by being in threaded connection with the external threads on the motor, and the rotation direction of the motor in the working process is the pre-tightening threaded connection direction of the motor and the support. According to the motor installation structure, the motor is connected with the support in a threaded connection mode, during installation, connection can be rapidly achieved without assistance of additional tools, additional connecting materials are not needed, the installation cost is reduced, and the installation technological process is simplified. The motor connection structure is simpler, and the material cost of the motor is effectively reduced. The rotation direction of the motor during working is the pre-tightening screwing direction of the motor and the support, so that the stability of connection between the support and the motor in the working process is effectively guaranteed, and the problem that the installation stability of the motor is affected by looseness of a connecting piece or vibration noise is caused by looseness is avoided. The invention further relates to a fan and an extractor hood comprising the motor mounting structure.
