Problems solved by technology

However, the carbon brush assembly of this type of motor still has the following problems: 1. The conductive metal assembly of this type of motor includes two conductive strips, which are stuck on the body of the brush holder plate and will loosen after long-term use. Causes increased noise and affects the stability of the motor
2. Since the conductive strips cross the bottom of the carbon brush assembly, and both the conductive strip and the carbon brush assembly are heating elements, this will cause concentrated heat and affect the service life of the motor; 3. The heat dissipation effect of the brush holder plate itself Not good, because it is necessary to ensure that the body of the brush holder board has sufficient strength to facilitate the installation of conductive strips and carbon brush components, resulting in fewer cooling holes on the body of the brush holder board, and sufficient board surface is needed to strengthen the strength

Abstract

The invention discloses a brush carrier assembly of an automobile radiator fan motor.The brush carrier assembly comprises a brush carrier plate, wherein the brush carrier plate comprises a brush carrier plate body and conductive metal assemblies arranged on the brush carrier plate body, each conductive metal assembly comprises a first connecting strip, a second connecting strip and a pair of connecting pieces, a first inductor connecting portion, a first carbon brush connecting portion and a third carbon brush connecting portion are arranged on each first connecting strip, a second carbon brush connecting portion, a fourth carbon brush connecting portion and a second inductor connecting portion are arranged on each second connecting strip, the outer contour, close to the brush carrier plate body of each first connecting strip extends in an arc-shaped mode and is located on the outer side of a corresponding carbon brush assembly, and each second connecting strip comprises an outer contour close to the brush carrier plate body, an outer arc-shaped section and an inner concave arc-shaped section located on the outer side of a fourth carbon brush assembly and an extending section transversely penetrating through the bottom of a third carbon brush assembly.The conductive metal assemblies of the brush carrier assembly reasonably avoid the areas of the carbon brush assemblies and make heat dissipated, and meanwhile the strength of the brush carrier plate body is improved.

Description

technical field [0001] The invention relates to a brush holder plate assembly, in particular to a brush holder assembly for an automobile radiator fan motor. Background technique [0002] The brush holder assembly of the automobile cooling fan motor generally includes a brush holder board, a carbon brush assembly and an inductor. The brush holder board includes a brush holder board body and a conductive metal assembly arranged on the brush holder board body. The carbon brush installation area and the inductance installation area, and the distribution of the general carbon brush assembly is uniformly distributed on the circumference and set at 90° to each other. The motor with this structure will waste a lot of effective segments due to the winding of the rotor assembly. Therefore, once When the output power of the motor is relatively high, the rotor assembly will be constrained by volume and the output power cannot be increased. And there is another kind of distribution of ...
