The purpose of this utility model is to overcome described in above prior art not enough, and a kind of magnetic tile fixing device that can prevent brush carrier dislocation simultaneously and fix the anti-brush carrier dislocation of automobile air conditioner motor reliable, simple in structure of magnetic shoe is provided.
The utility model is achieved through the following technical solutions: the magnetic tile fixing device of the anti-brush carrier dislocation of automobile air conditioner motor, comprise motor housing, magnetic shoe, brush carrier, it is characterized in that: also comprise U-shaped spring, magnetic shoe geometrical clamp, described magnetic shoe is fixed in magnetic shoe geometrical clamp, between every two adjacent described magnetic shoe geometrical clamps, be provided with U-shaped spring, described U-shaped spring fits on motor housing inwall described magnetic shoe geometrical clamp stretching, and described magnetic shoe geometrical clamp bottom is provided with anti-brush carrier dislocation boss.
Further, described magnetic shoe geometrical clamp is comprised of connector, anti-brush carrier dislocation boss, magnetic shoe limit body, described every two magnetic shoe limit bodies and a vertical fixing magnetic shoe geometrical clamp suitable with magnetic shoe profile that forms of connector, the inner side that described magnetic shoe limit body contacts with magnetic shoe is provided with magnetic shoe limited impression, be provided with U-shaped spring stopper slot with the discontiguous outside of magnetic shoe, the top that magnetic shoe limit body contacts with connector is provided with magnetic shoe positive stop lug boss.
Preferably, described U-shaped spring is limited in two adjacent spacing U-shaped spring stopper slots of carrying of magnetic shoe.
Further, in each described magnetic shoe geometrical clamp, described in it, the interval of magnetic shoe limited impression and the width of magnetic shoe are consistent, and the height of described magnetic shoe limit body is consistent with the height of magnetic shoe.
The utility model integrates anti-brush carrier dislocation and fixes magnetic shoe function, solid and reliable, simple in structure, easy to use, both guaranteed that brush and magnetic shoe relative position were constant, can solve again the problem that current automobile air conditioner motor exists magnetic shoe to come off or is shifted, improve production efficiency, overcome the deficiency of prior art.
