An end cap is arranged at one end of the casing; a rotor comprises a motor shaft; the motor shaft penetrates the casing; a commutator is arranged at one end of the motor shaft, close to the end cap; a grooving is arranged at a bottom of the end cap, to form a brush house; a carbon brush is arranged in the brush house; one end of the carbon brush is presses against the commutator; a clamping mechanism is arranged at a sidewall of the end cap; an ear protuberance is arranged at corresponding positions on the casing and the clamping mechanism; and the ear protuberance is arranged with the clamping mechanism in a clamp manner. The end cap of the integrated vehicle-mounted heater unit motor adopts an integral molding manner of the brush house and the end cap; the brush house is directly arranged on the end cap; the motor structure is simplified; and simultaneously the casing and the end cap of the integrated vehicle-mounted heater unit motor adopts a manner that the clamping mechanism is directly clamped with the ear protuberance on the casing, the clamping mechanism and the end cap are integrally molded, and the ear protuberance and the casing are integrally molded, so that quantity of components is reduced, production cost is reduced, and production efficiency is increased.
Description
Technical field
The utility model relates to the motor of automobile with warm-air drier, is specifically related to a kind of integrated car warm-air drier motor.
Background technology
Warm-air drier on the automobile generally adopts motor to drive, and the motor of automobile-used warm-air drier generally comprises casing and is arranged on casing interior stator and rotor.One end of casing is provided with end cap, and the end cap below is provided with carbon brush holder, and carbon brush holder is provided with carbon brush, and end cap is fixed together by the mode and the casing of bolt.This motor is provided with carbon brush holder, complex structure, and complex production process, and the mode of bolt need be fixed with screw, number of spare parts is more, the production cost height.
Summary of the invention
The purpose of this utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a kind of integrated car warm-air drier motor simple in structure, effectively reduces production cost, has improved production efficiency.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of integrated car warm-air drier motor, comprise casing and be arranged on the interior magnetic loop system of casing, one end of casing is provided with end cap, rotor comprises motor shaft, described motor shaft passes and runs through casing, motor shaft is provided with commutator near an end of end caps, described end cap bottom is provided with fluting, form the brush room, brush is provided with carbon brush within doors, and carbon brush one end and commutator offset, and described end cap sidewall is provided with fixture, it is prominent that described casing and fixture corresponding position are provided with ear, and ear is prominent to engage setting with fixture.
End cap in the utility model adopts high temperature resistant bakelite material, and cost is lower.
As preferably, described fixture comprises the young and second ear son of first ear, and described ear is prominent to be snapped between the young and second ear son of first ear, forms closely engaging setting.After adopting above-mentioned preferred version, integrated car warm-air drier motor of the present utility model utilizes the young and second ear son of first ear of fixture that prominent clamping of the ear on the casing removed from screw and fixed, and the reduction number of spare parts saves production cost.
As preferably, the sidewall of described carbon brush and brush room and commutator acutangulates setting.After adopting above-mentioned preferred version, carbon brush is angled with the sliding surface and the commutator shaft synform in brush room, and according to Pythagorean theorem, can prolong hypotenuse is the length of carbon brush, thereby improves the effective length of carbon brush, prolongs the motor life-span.
In addition, the magnetic loop system design of employing thickening of the present utility model, the magnetic energy that effectively reduces stator field is revealed, avoided use very-high performance permanent magnet, improved power bulk density ratio with the volume motor, indirect saving raw material, reduce material cost.
The end cap of integrated car warm-air drier motor of the present utility model adopts brush room and end cap integrated molding, the brush room is set directly on the end cap, simplified the structure of motor, simultaneously, casing of the present utility model and end cap adopt fixture and the ear on the casing to advance by leaps and bounds and go and directly engage, and fixture and end cap are one-body molded, ear is prominent one-body molded with casing, reduce amount of parts, reduced production cost, improved production efficiency.
