Abstract
The utility model discloses a motor having a compact structure, and relates to the technical field of motor manufacturing and processing. The motor comprises a bearing chamber structure of a motor end cap, a commutator, a connection structure of a housing and the end cap, wherein the bearing chamber structure of the motor end cap helps to save installation space through a quincuncial rivet joint method; the commutator is provided with a hollow-out part; and the housing and the end cap are in rivet joint. According to the motor having the compact structure, corresponding design is conducted on the housing, the bearing chamber and the commutator of the motor, and the size of the motor is only one third of that of a conventional motor.
Description
Technical field
The utility model relates to motor and manufactures processing technique field, relates in particular to a kind of motor of compact conformation.
Background technology
Along with the development of automobile industry, evaporation motor for automobile accessories requires also more and more higher, especially the volume to motor, weight require strict especially, traditional motor case is connected by screw-nut and completes with end cap, so just need in stator (casing is connected rear with end cap), reserve the space of screw or nut, make stator become large, it is large and heavy that motor entirety just becomes volume, screw-nut is connected under long-term motion and vibration and can fluffs in addition, affects the safety in utilization of motor.For adapting to the growth requirement of current automobile, the limited space that can provide to air-conditioning system on whole automobile, should this must develop the motor that a kind of volume is little, our company has carried out corresponding design (as shown in Figure 1 and Figure 2) for bearing chamber structure and the commutator of electric motor end cap, reduce certain volume, in order further to reduce the volume of motor, be necessary the casing of motor to process accordingly.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is how under the prerequisite that keeps power, to reduce the volume of motor.
(2) technical scheme
In order to address the above problem, the utility model provides a kind of motor of compact conformation, and described motor comprises:
The bearing chamber structure of electric motor end cap, has saved installing space by plum blossom-shaped riveting method;
Commutator, described commutator is provided with openwork part;
The syndeton of casing and end cap, it comprises: casing and end cap, and the connecting portion outer wall of described casing is provided with annular protrusion, and the connecting portion outer wall of described end cap is provided with some riveting bars, by described riveting bar and the riveted joint of described annular protrusion, described casing and the riveted joint of described end cap.
Wherein, described riveting bar is 6, and circumferentially evenly arranging along described end cap connecting portion.
Wherein, described casing, electric motor end cap, the dead in line of commutator place.
Wherein, described riveting bar cross section is L shaped.
(3) beneficial effect
The shell of the utility model to motor, bearing chamber, commutator has carried out respective design, and the volume of this motor only has 1/3rd of conventional motors.
Accompanying drawing explanation
Fig. 1 is the structural representation of bearing chamber of the present utility model;
Fig. 2 is the structural representation of the utility model commutator;
Fig. 3 is the syndeton schematic diagram of the utility model casing and end cap;
Fig. 4 is the structural representation of casing in Fig. 3.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1～4, described motor comprises:
The bearing chamber structure 1 of electric motor end cap, has saved installing space by plum blossom-shaped riveting method;
Commutator 2, described commutator is provided with openwork part 20;
The syndeton 3 of casing and end cap, it comprises: casing 31 and end cap 30, the connecting portion outer wall of described casing 31 is provided with annular protrusion 311, the connecting portion outer wall of described end cap 30 is provided with some riveting bars 301, rivet by described riveting bar 301 and described annular protrusion 311, described casing 31 is riveted with described end cap 30.
In order to improve degree of fixation and easy to process, preferably, described riveting bar 301 is 6, and along circumferentially evenly the arranging of described end cap 30 connecting portions, wherein, described riveting bar 301 cross sections are L shaped.
Preferably, described casing 31, electric motor end cap 30, commutator 2 place deads in line.
Traditional connected mode, for casing and end cap are connected with nut by screw, so just need to be reserved the space of screw or nut in stator (casing is connected rear with end cap), makes stator become large.Another screw-nut is connected under long-term motion and vibration and can fluffs, and affects the useful life of motor.Therefore, this blower fan has adopted the design of riveted structure to the connected mode of casing and end cap, after innovating by improvement, make whole motor become very compact, reduce the overall weight of cost and blower fan, riveted structure can not fluff because of fan vibration simultaneously, therefore, also improved the reliability of blower fan, the bearing chamber structure 1 of the utility model to electric motor end cap, commutator 2, innovative design has been carried out in 3, three aspects of syndeton of casing and end cap, and the volume of this motor only has 1/3rd of conventional motors.
Above execution mode is only for illustrating the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
Claims (4)
1. a motor for compact conformation, is characterized in that, described motor comprises:
