Problems solved by technology

Most of the existing brush holders are of rigid structure. If rubber pads are not used to reduce vibration, then when the motor is running, the brushes installed on the brush holder will be in sliding contact with the rotor, causing the brush holder and the entire motor to vibrate, and the noise generated is relatively high. Big

Abstract

The invention discloses a motor brush frame. The motor brush frame comprises a bracket and a brush box arranged on the bracket; a plurality of connecting frames are arranged on the bracket in an extending manner; the brush box is supported at the upper end of the bracket through the connecting frames; an air guiding groove is formed in the inner wall of a brush cavity of the brush box; heat dissipation holes are formed in the side wall of the brush box; and a plurality of elastic buckles connected with a motor stator are symmetrically arranged on the periphery of the bracket. The motor brush frame disclosed by the invention adopts an elastic vibration damping structure with integrated brush box and brush frame, so that motor vibration and generated noise can be lowered; and by virtue of the novel structure of the motor brush frame, a rubber-cushion-free and low-noise design of the motor can be realized, and meanwhile, assembling processes are reduced.

Description

technical field [0001] The invention relates to a motor device, in particular to a motor brush holder and a motor using the brush holder. Background technique [0002] With the improvement of people's living standards, consumers have put forward higher requirements for the noise, volatile organic compounds (Volatile Organic Compounds, volatile organic compounds) and odor of electrical products in automobiles, and air-conditioning blowers are the first to bear the brunt. In order to reduce noise, most of the current vehicle air-conditioning blower products adopt the design of carbon brush holder with rubber pad vibration damping structure, including brush box 41, brush holder plate 42 and rubber pad 43. The brush holder is a rigid structure, such as figure 1 As shown, but with this structural design, it is necessary to use rubber pads, which will emit volatile organic compounds and produce unpleasant odors. If you want to solve the VOC and odor problems, you must replace the...
