Abstract
The invention discloses a motor carbon brush frame, and belongs to the technical field of direct-current permanent magnet motors. The motor carbon brush frame is applied to the automobile air-conditioner industry and comprises a front end cover, a carbon brush and two brush holders, wherein each brush holder is integrally formed by high temperature resisting materials in an injection moulding mode, the brush holders are connected with the carbon brush, and the two brush holders are symmetrically arranged on two sides of the front end cover and connected with the front end cover. According to the motor carbon brush frame, a conventional brush box board mode is abandoned, each brush holder is integrally formed by the high temperature resisting materials in the injection moulding mode, the carbon brush is installed in an interference fit mode, and structural reliability is guaranteed.
Description
Technical field
The present invention relates to belong to the direct current permanent magnet motor technical field, be applied to the air conditioning for automobiles industry, particularly a kind of carbon brush frame for motor.
Background technology
The problem that the warm-air drier ubiquity life-span is short.The tradition warm-air drier is all that carbon brush is arranged on the brush box plate, and by spring top its contact commutator of sening as an envoy to, and the warm-air drier volume is little, and the radial space deficiency, just can only be used the shorter carbon brush of length, finally affects electrical machinery life.Tradition brush box plate needs the riveting brush box, and row's bus, install carbon brush, and operation is many, and due to the warm-air drier small volume, structure is relative compact again, aspect high temperature resistant, is short of to some extent.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is, a kind of carbon brush holder simple in structure is provided, and guarantees structural reliability.
(2) technical scheme
In order to address the above problem, the invention provides a kind of carbon brush holder, described carbon brush holder comprises: front end housing, carbon brush, two brush carriers, high temperature resistance material integrated injection molding for described brush carrier, described brush carrier is connected with described carbon brush, described two brush carriers are symmetrically set in the both sides of described front end housing, and are connected with described front end housing.
Wherein, described brush carrier is by the injection mo(u)lding of PA66 high temperature resistance material.
Wherein, the end of described carbon brush is " crescent ".
Wherein, the connecting portion of described brush carrier is provided with raised ribs, and described carbon brush is connected with described brush carrier by raised ribs.
Wherein, described carbon brush holder also comprises casing, and described front end housing is connected with described casing by screw.
Wherein, described front end housing and described brush carrier clamping.
Wherein, the groove of described brush carrier middle part is provided with linkage unit, and described linkage unit is connected with described front end housing by flexible member.
Wherein, described flexible member is spring.
(3) beneficial effect
The brush box plate mode of abandoning tradition of the present invention, with high temperature resistance material integrated injection molding brush carrier, install carbon brush in the mode of interference fit, guaranteed structural reliability.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the combination schematic diagram of brush carrier and carbon brush in Fig. 1;
Fig. 3 is the decomposing schematic representation of brush carrier and carbon brush in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
Shown in Fig. 1～2, described carbon brush holder comprises: front end housing 1, carbon brush 30, two brush carriers 3, described brush carrier 3 use high temperature resistance material integrated injection moldings, described brush carrier 3 is connected with described carbon brush 30, described two brush carriers 3 are symmetrically set in the both sides of described front end housing 1, and are connected with described front end housing 1.
Preferably, described brush carrier 3 is by the injection mo(u)lding of PA66 high temperature resistance material.Owing to having abandoned traditional brush box plate, use brush carrier, motor upper cover the is formed structure of open type, aspect heat radiation, the little blower fan of other power larger volumes has greatly improved relatively, the brush box plate mode of abandoning tradition, the special PA66 high temperature resistance material injection mo(u)lding brush carrier of using, install carbon brush in the mode of interference fit, guaranteed structural reliability.
Preferably, the end of described carbon brush 30 is " crescent ", by straight carbon brush originally, makes present " selenodont ", has increased effective break-in length, has extended the life-span of motor.
Preferably, the connecting portion of described brush carrier 3 is provided with raised ribs 33, and described carbon brush 30 is connected with described brush carrier 3 by raised ribs 33.
Preferably, described carbon brush holder also comprises casing 2, and described front end housing 1 is connected with described casing 2 by screw 10.
Preferably, described front end housing 1 and described brush carrier 3 clampings.
Preferably, the groove of described brush carrier 3 middle part is provided with linkage unit 31, and described linkage unit 31 is connected with described front end housing 1 by flexible member 310.
The present invention has following advantage:
One, this scheme only needs the injection mo(u)lding brush carrier, and then carbon brush is installed, and has simplified technique, has reduced operation, has saved cost.
Two, this scheme, in the situation that operational environment allows, is compared the blower fan of existing sealing, and the upper end cover of its open type can distribute the heat that machine operation produces faster, and the machine operation performance is guaranteed, and high temperature resistant property is significantly improved.
Three, adopt this kind " selenodont " to coordinate the structure of brush carrier, the length that has effectively extended carbon brush, be improved the life-span of product.
Above execution mode is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
