In a preferred embodiment of the present invention, the rectangular top wall is provided with a ventilation hole, a ventilation portion is provided between adjacent clamping structures, and cooling air enters from the ventilation portion and exits from the ventilation hole to cool the carbon brush in the brush holder.
Due to the adoption of the technical scheme, the utility model discloses an adopt the joint mode to be connected between brush holder and the brush board for the assembly is simple. In addition, the rectangular top wall is provided with ventilation holes, ventilation parts are arranged between the adjacent clamping structures, cooling air enters from the ventilation parts, the ventilation holes exit, the carbon brush in the brush holder is cooled, the cooling speed is high, and the service life of the carbon brush is prolonged.
Drawings
Fig. 1 is a schematic view of the brush plate assembly structure of the motor of the cooling fan of the present invention.
Fig. 2 is an assembly diagram of the brush holder, the carbon brush and the brush plate of the present invention.
Fig. 3 is a schematic view of the brush holder structure of the present invention.
Detailed Description
The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, a brush holder structure of a motor of a cooling fan for an automobile, shown in the figures, includes a brush holder 30 for mounting a carbon brush 10 on a brush plate 20, wherein the brush holder 30 is connected with the brush plate 30 in a snap-fit manner. The method comprises the following steps:
the brush holder 30 has a rectangular top wall 31 and four engaging structures 32 with a pair of long sides adjacent to a pair of short sides, and each engaging structure 32 is engaged with the engaging groove structure 21 on the brush plate 20.
Each clamping structure 32 comprises an inserting piece 32a vertically connected with the rectangular top wall 31, a card slot 32aa is arranged on the inserting piece 32a, a card 32b is arranged in the card slot 32aa, the card 32b and the inserting piece 32a are integrally formed, the card 32b and the inserting piece 32 form a certain included angle, and the free end of the card 32b protrudes out of the card slot 32 aa; after the insertion sheet 32a is inserted into the slot 21a in the slot structure 21, the card 32b is ejected into the slot 21b in the slot structure 21 for clamping; when the brush holder 30 needs to be removed from the brush plate 20, the free end of the card 32b is pushed inward into the card slot 32aa of the insertion piece 32a, and is separated from the card slot 21b in the card slot structure 21, so that the brush holder 30 can be pulled out.
In order to enhance the cooling of the carbon brush 10 and to prolong the service life of the carbon brush 10, the rectangular top wall 31 is provided with ventilation holes 31a, ventilation parts 33 are arranged between adjacent clamping structures 32, and cooling air enters from the ventilation parts 33 and exits from the ventilation holes 31a to cool the carbon brush 10 in the brush holder 30.
