Description
Technical field
The present invention relates to a kind of motor casing structure.
Background technology
The effect or the function of general permanent magnet DC motor casing: the one, as magnetic shoe and armature shaft bearing fixing part, the 2nd, as the yoke in the magnetic circuit, promptly as the part of motor magnetic circuit magnetic line of force path, so the permanent magnet DC motor casing is all made by soft magnetic material, because they are magnetization and demagnetization easily, and has very high permeability, can play the effect of the good gathering magnetic line of force, so be widely used for path, promptly be used as the yoke of magnetic circuit as the magnetic line of force.The thickness of general casing is to be determined as the yoke in the magnetic circuit by casing, during machine operation, casing is as a magnetic circuit part, play the effect of the good gathering magnetic line of force, pass through magnetic flux, promptly when design, the thickness of casing is to allow the magnetic flux density decision by the maximum by casing, and, casing passes through the magnetic line of force as the yoke in the magnetic circuit, because the casing of soft magnetic material has the effect of the good gathering magnetic line of force, so have only that part of casing that contacts with magnetic shoe as the yoke in the magnetic circuit by the magnetic line of force, the other parts of casing and motor magnetic circuit have nothing to do, it mainly acts on or function is as magnetic shoe and armature shaft bearing fixing part, accordingly, the design thickness of this part casing is just determined by the mechanical performance (intensity and rigidity) of casing.General permanent magnet DC motor casing is formed by low carbon steel plate punching press or stretching, the punching press or the front and back that stretch, the thickness of casing is uniformity basically, and its thickness is as the yoke design in the magnetic circuit, corresponding to as magnetic shoe and armature shaft bearing fixing part, it is too thick that thickness is just disliked, be casing as the yoke part, thickness is suitable, and other parts do not need such thickness, like this, the design of casing uniform thickness makes material cause waste.
Summary of the invention
Technical problem to be solved of the present invention provides a kind of motor casing structure of economical with materials, thereby overcomes the shortcoming that causes waste of material in the existing permanent magnet DC motor casing uniform thickness design.
The present invention is achieved by the following technical solutions: a kind of motor casing structure, comprise chassis body, described chassis body is a thin-walled design, and chassis body is provided with and the close-fitting yoke edge of chassis body cover, and the yoke edge puts and is provided with the fixedly positioning boss and the magnetic shoe contained side of magnetic shoe.
Thus, chassis body is a thin-walled design, satisfy the mechanical performance (intensity and rigidity) of design needs, yoke edge cover passes through the magnetic line of force with chassis body, assemble the magnetic line of force well as the yoke in the magnetic circuit, under the duplicate situation of function, saved material, this innovative design, saving case material weight is the 30%-45% of former weight.
The invention has the advantages that the saving material, reduce part, reduce cost, reduce product weight, improved the lightweight of automobile accessories motor.

Embodiment
With reference to accompanying drawing 1 to accompanying drawing 8, the present invention is a kind of motor casing structure, comprise chassis body 1, chassis body 1 is a thin-walled design, the design thickness of chassis body 1 is just determined by the mechanical performance (intensity and rigidity) of casing, rather than determine as the yoke design in the magnetic circuit, chassis body 1 is provided with yoke edge cover 2, chassis body 1 fits in yoke edge cover 2 tight no gaps and is one, the thickness of chassis body 1 and yoke edge cover 2 constitutes the yoke design thickness in the magnetic circuit, and yoke edge cover 2 is provided with the fixedly positioning boss 3 and the magnetic shoe contained side 4 of magnetic shoe.As a kind of embodiment of the present invention, yoke edge cover 2 is provided with two positioning boss 3 that are oppositely arranged, be respectively equipped with four magnetic shoe contained sides 4 with the yoke of each positioning boss 3 corresponding side edge cover 2 near the semi-ring position, two one group of both sides that are arranged on semi-ring, four magnetic shoe contained sides 4 are used for fixing a side magnetic shoe 5, are respectively equipped with at least two magnetic shoe contained sides 4 with the yoke edge cover 2 of each positioning boss 3 corresponding side near the semi-ring position certainly and can fix a side magnetic shoe 5.Magnetic shoe 5 is provided with magnetic shoe detent 6, and when mounted, magnetic shoe detent 6 matches with positioning boss 3, accurately locatees, and then magnetic shoe contained side 4 is pulled to magnetic shoe 5, clamps magnetic shoe 5, makes accurately location and fixing, the position of magnetic shoe 5 in casing.Thus, the fixedly magnetic shoe folder of magnetic shoe has been saved in the innovative design of this magnetic shoe positioning and fixing, and makes magnetic shoe location and fixing more reliable and convenient.
The present invention finishes by following procedure of processing:
1, chassis body 1 is formed by low carbon steel plate punching press or stretching, as shown in Figure 3, Figure 4;
2, punch process goes out positioning boss 3 and magnetic shoe contained side 4 in yoke edge cover 2, as Fig. 5, shown in Figure 6;
3, when making magnetic shoe 5, can be shaped on magnetic shoe detent 6 at magnetic shoe 5 and positioning boss 3 opposite positions, as shown in Figure 8;
4, before assembling magnetic shoe 5, yoke edge cover 2 is pressed in the chassis body 1, yoke edge cover 2 is cooperated with chassis body 1 tight no gap, the composition one, and yoke is inlayed overlap 2 and the relative position of chassis body 1 adhere to specification, as shown in Figure 1 and Figure 2;
5, in the sub-assembly with magnetic shoe 5 load maps 1, the magnetic shoe setting circle groove 6 of magnetic shoe 5 is matched with the magnetic shoe positioning boss 3 of yoke edge cover 2, then the magnetic shoe contained side 4 of yoke edge cover 2 is detained to magnetic shoe 5, and magnetic shoe 5 is clamped, as Fig. 7, shown in Figure 8.
Under the duplicate situation of function, motor casing structure of the present invention is compared with uniform thickness designed motor casing in the prior art, can save the 30%-45% that case material weight is former weight.
The invention has the advantages that the saving material, reduce part, reduce cost, reduce product weight, improved the lightweight of automobile accessories motor. The present invention can be applicable in the various permanent magnet D. C. motors supporting on the automobile, such as the wiper motor of various models.
