Abstract
The invention discloses an electric motor with a compact structure, and relates to the technical field of electric motor manufacturing. The electric motor comprises a bearing chamber structure of an end cap of the electric motor, a commutator, a motor shell and a connecting structure of the end cap, wherein the bearing chamber structure is arranged through a plum blossom shape riveting mode to save mounting space, the commutator is provided with a hollow-out part, and the motor shell is connected with the end cap in a riveting mode. Due to the fact that corresponding design is carried out on the outer shell, the bearing chamber and the commutator of the electric motor, the size of the electric motor is only one third of that of a traditional electric motor.
Description
Technical field
The present invention relates to motor and manufacture processing technique field, relate in particular to a kind of motor of compact conformation.
Background technology
Development along with automobile industry, evaporation motor for automobile accessories requires also more and more higher, especially to volume, the weight of motor, 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, the motor integral body volume that just becomes is large and heavy, 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, reduced certain volume, in order further to reduce the volume of motor, be necessary the casing of motor is processed accordingly.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention 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 invention provides a kind of motor of compact conformation, described motor comprises:
The bearing chamber structure of electric motor end cap, saved installing space by the plum blossom-shaped riveting method;
Commutator, described commutator is provided with openwork part;
The syndeton of casing and end cap, described casing and the riveted joint of described end cap.
Wherein, the syndeton of described casing and end cap 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.
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 present invention to motor, bearing chamber, commutator has carried out respective design, and the volume of this motor only has 1/3rd of conventional motors.
The accompanying drawing explanation
Fig. 1 is the structural representation of bearing chamber of the present invention;
Fig. 2 is the structural representation of commutator of the present invention;
Fig. 3 is the syndeton schematic diagram of casing of the present invention and end cap;
Fig. 4 is the structural representation of casing in Fig. 3.
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. 1～4, described motor comprises:
The bearing chamber structure 1 of electric motor end cap, saved installing space by the plum blossom-shaped riveting method;
Commutator 2, described commutator is provided with openwork part 20;
The syndeton 3 of casing and end cap, described casing 31 and described end cap 30 riveted joints.
Preferably, the syndeton of described casing and end cap comprises: casing 31 and end cap 30, the connecting portion outer wall of described casing 31 is provided with annular protrusion 311, and the connecting portion outer wall of described end cap 30 is provided with some riveting bars 301, by described riveting bar 301 and 311 riveted joints of described annular protrusion.
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, has reduced 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 present invention to electric motor end cap, commutator 2, innovative design has been carried out in 3, three aspects of the 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 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.
