Abstract
The utility model discloses a kind of automobile lifter motor commutator lid, comprise housing and two carbon brush; Described housing comprises large end, central enclosure and small end; Described two carbon brush symmetry is arranged on the central enclosure sidewall of large end; The same side of large end lateral wall is fixed with symmetrically two springs, spring is formed by iron wire coiling, and an end of iron wire contacts with the exposed end section outside housing sidewall of carbon brush; Two exposed outboard ends in housing sidewall of carbon brush are all connected with plain conductor; The other end of plain conductor is fixed on by connector on the opposite side of hull outside wall; Central enclosure, the excircle corresponding with carbon brush is provided with the draw-in groove that restriction carbon brush swings.Due to the design of housing, and the application of spring and plain conductor, reduce the risk that motor produces metallic noise, the demand of client in noise reduction can be met well.
Description
Technical field
The utility model relates to a kind of motor commutator lid, particularly a kind of lifter dynamo of autocar glass rectification
Son lid, belongs to auto-parts.
Background technology
Current domestic increasing vehicle requires that vehicle window has a key elevating function, and will have the pinch resistant functionality meeting the regulations such as Europe superscript, so the Anti-pinch motor of inline e module is trend of the times.And alternating current is become direct current by commutator, produce unidirectional moment, drive motor rotates, and is the foundation of direct current machine.Communtator cover, the device as fixing carbon brush position is arranged on motor internal, is the requisite components and parts of all direct current machines.
But existing communtator cover structure carbon brush is fixed by reed, the easy vertical tremor of reed, produce metallic noise, the demand of client on noise can not be met well.
utility model summary of the invention
Goal of the invention: the communtator cover element that the utility model provides a kind of structure optimization, performance better, to overcome the high defect of existing communtator cover metallic noise frequency.
Technical scheme: a kind of automobile lifter motor commutator lid, comprises housing and two carbon brush; Described housing comprises large end, central enclosure and small end, and large end is connected with elevator motor, and central enclosure and small end are enclosed within the rotor of elevator motor; Described two carbon brush symmetry is arranged on the central enclosure sidewall of large end; The exposed outboard end in housing sidewall of described two carbon brush is all connected with plain conductor one end; Two strands of plain conductor other ends connect connector respectively, and are fixed on hull outside wall by connector; Two connector symmetries are connected on the same side of the hull outside wall of large end, and each connector is provided with two pawls in the same way, and the hull outside wall corresponding with connector installation side is provided with two springs; Spring is arranged on housing by the cylinder fixture on large end lateral wall, spring is formed by iron wire coiling, iron wire is around on cylinder fixture, and an end contacts with the exposed end section outside housing sidewall of carbon brush, and another end is spacing in housing sidewall by the spacing preiection in housing sidewall.
Described central enclosure, the hull outside wall corresponding with carbon brush is provided with the draw-in groove that restriction carbon brush swings.
Described connector is the connector that latten(-tin) is made.
The axis of described cylinder fixture is axially parallel with housing.
Described iron wire two end is towards the opposite.
Operation principle: the automobile lifter motor commutator lid that the utility model provides, after being put into gearcase, is extruded by stator, meeting retracting spring, thus the motion that when restrict rotor is rotated, carbon brush is axially outside, make carbon brush and commutator keep in touch.
Beneficial effect: the automobile lifter motor commutator lid that the utility model provides, the application of spring, makes carbon brush and commutator keep in touch; The design of draw-in groove on housing, limits the swing of carbon brush; In addition, the plain conductor of use also not easily rocks, thus significantly reduces the probability that motor produces particular noise.
Accompanying drawing explanation
Fig. 1 is the automobile lifter motor commutator lid structural representation of the utility model embodiment;
Fig. 2 is the carbon brush catenation principle figure of the utility model embodiment.
Embodiment
Below in conjunction with specific embodiment, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As depicted in figs. 1 and 2, automobile lifter motor commutator lid comprises housing 1 and two carbon brush 6, and stepped housing 1 comprises large end 2, central enclosure 3 and small end, and two carbon brush 6 symmetries are arranged on central enclosure 3 sidewall of large end 2.
The same side of large end 2 lateral wall is provided with two cylinder fixtures 4 symmetrically, is used for fixing two springs 5, and the axis of cylinder fixture 4 is axially parallel with housing 1; Spring 5 is formed by iron wire coiling, and iron wire two end is towards the opposite, and wherein an end is spacing on housing 1 sidewall by the spacing preiection on housing 1 lateral wall, and another end contacts with the exposed end section outside housing 1 sidewall of carbon brush 6; Two exposed outboard ends at housing 1 sidewall of carbon brush 6 are all connected with plain conductor 7; The other end of two strands of plain conductors 7 connects connector 8 respectively, and is fixed in the respective side of housing 1 lateral wall cylinder fixture 4 by connector 8; Two connector 8 symmetries are connected on housing 1 lateral wall of large end 2.
The connector that connector 8 is made for latten(-tin); Each connector is provided with two pawls in the same way, is convenient to communtator cover and puts into gearcase.
Central enclosure 3, the hull outside wall corresponding with carbon brush 6 is provided with the draw-in groove 9 limiting carbon brush 6 and swing.
When electrical power, rotor operates, the application of spring 5, limits the motion that carbon brush 6 is axially outside, and carbon brush 6 and commutator are kept in touch; The design of draw-in groove 9 on housing 1, limits the swing of carbon brush 6; In addition, plain conductor 7 also not easily rocks, and the automobile lifter motor commutator lid that therefore the utility model provides reduces the risk that motor produces metallic noise, can meet the demand of client in noise reduction well.
