A stator assembly 10, an electric machine, and a vehicle provided in accordance with some embodiments of the present invention are described below with reference to fig. 1-6.

As shown in fig. 1, a first embodiment of the present invention provides a stator assembly 10 comprising: a core structure 100, a first insulating frame 106, and a second insulating frame 108.

As shown in fig. 1 and 6, the iron core structure 100 includes an iron core 102 and an insulator 104, wherein the iron core 102 and the insulator 104 are connected to each other, and the insulator 104 ensures the insulation requirement of the iron core 102. Further, the core structure 100 has a first end 110 and a second end 112 in the axial direction, and the first insulating frame 106 and the second insulating frame 108 are detachably mounted on the first end 110 and the second end 112, respectively. Therefore, the reliability of a prototype can be ensured when the motor is developed in the early stage, and the development period is shortened.

In particular, as shown in fig. 1 and 6, the present invention optimizes the connection position and connection manner of the first and second insulating

frames

106 and 108. Specifically, in the present invention, the first insulating frame 106 is disposed at a first axial end 110 of the core structure 100, and the second insulating frame 108 is disposed at a second axial end 112 of the core structure 100; that is, the stator assembly 10 is designed in a three-stage manner in the axial direction, and the first insulation frame 106 and the second insulation frame 108 are not inserted to both sides of the core structure 100. In addition, the first insulating frame 106 and the second insulating frame 108 are not inserted into both sides of the core structure 100, and both the first insulating frame 106 and the second insulating frame 108 are detachably connected directly to the insulator 104.

As shown in fig. 1 and 6, in the stator assembly 10 according to the present invention, the first insulating frame 106 and the second insulating frame 108 can be applied to the core structures 100 having different axial dimensions, and the versatility of the first insulating frame 106 and the second insulating frame 108 is achieved. Therefore, the problems of low reliability and long development period in the early development of the motor can be effectively solved, and the development cost of the motor can be reduced.

Therefore, as shown in fig. 1 and fig. 6, in the present embodiment, the first insulating frame 106 and the second insulating frame 108 are detachably connected to the insulator 104, and the mounting positions of the first insulating frame 106 and the second insulating frame 108 are optimized, so that the universality of the first insulating frame 106 and the second insulating frame 108 is realized, the reliability of the operation of the sample machine during the early development of the motor is ensured, and the development cycle of the motor is further shortened.

A second embodiment of the utility model proposes a stator assembly 10, further comprising, on the basis of the first embodiment:

as shown in fig. 4 and 5, the core body 102 and the insulator 104 are integrally injection molded. Further, during the injection molding of the core structure 100, the core structures 100 having unequal axial dimensions may be produced by adjusting the inserts of the injection mold. Thus, the mold can be a universal mold, and the axial dimension of the core structure 100 can be designed according to actual needs.

In addition, since the first insulating frame 106 and the second insulating frame 108 are connected to the axial ends of the core structure 100, and the first insulating frame 106 and the second insulating frame 108 are connected to the insulator 104, it is ensured that the first insulating frame 106 and the second insulating frame 108 can be used with core structures 100 having different axial dimensions.

In this embodiment, further, the insulator 104 is an injection molded body as shown in fig. 4 and 5, and the injection molded body is directly injection molded. In this way, the size of the injection molded body can be adjusted by adjusting the insert of the injection mold during the injection molding of the core structure 100.

In this embodiment, it should be noted that the injection mold is used for manufacturing the core structure 100, and the embodiment explains the specific structure of the injection mold too much, and a person skilled in the art can understand it.

Therefore, the stator assembly 10 of the present embodiment directly injection molds the iron core 102 and the insulator 104 into a single body. Thus, when the axial dimension of the core structure 100 changes, the insert of the injection mold is adjusted to adapt to the core height of the dimension, so that the injection mold becomes a general mold.

And, first insulating frame 106 sets up at the axial first end 110 of core structure 100, and second insulating frame 108 sets up at the axial second end 112 of core structure 100, and stator module 10 is the syllogic design in the axial for first insulating frame 106 and second insulating frame 108 can be applicable to the different core structure 100 of axial size, and as long as the wire winding diameter that the motor used is the same, first insulating frame 106 and second insulating frame 108 are just general, are fit for the different iron core structure 100 of size and use.

In addition, the stator assembly 10 of the present embodiment has all the advantages of the stator assembly 10 of the first embodiment. On one hand, the problems of low reliability and long development period in the early development of the motor can be effectively solved, and on the other hand, the development cost of the motor can be reduced, and the detailed discussion is omitted.

A third embodiment of the present invention provides a stator assembly 10, further comprising, in addition to the first and second embodiments:

as shown in fig. 2 and 4, the insulator 104 is provided with a first connecting portion 114, and the first insulating frame 106 is provided with a second connecting portion 116. The first connecting portion 114 is disposed at the axial first end 110 of the core structure 100, and the first connecting portion 114 can be detachably connected to the second connecting portion 116, so as to ensure the detachable connection between the insulator 104 and the first insulating frame 106.

Specifically, as shown in fig. 2 and 4, the first connecting portion 114 is disposed on the insulator 104 and located at the first end 110 of the core structure 100 in the axial direction. In this way, after the first insulating frame 106 is connected to the insulator 104, it is ensured that the first insulating frame 106 is located at the first end 110 in the axial direction of the core structure 100, so that the first insulating frame 106 and the insulator 104 are distributed in the axial direction of the stator assembly 10, and the first insulating frame 106 is not inserted to the peripheral side of the core structure 100.

Thus, on the basis of ensuring that the first insulating frame 106 is connected to the insulator 104, the size of the entire core structure 100 does not need to be considered, and the size of the first insulating frame 106 does not need to be changed according to the core structure 100, so that the universality of the first insulating frame 106 is realized.

In this embodiment, further, as shown in fig. 2 and 4, the insulator 104 includes a first connection face 118, and the first connection portion 114 is disposed on the first connection face 118. In addition, the first insulating frame 106 is provided with a second connection surface 120, and the second connection portion 116 is provided on the second connection surface 120. Thus, when the first connecting portion 114 is connected to the second connecting portion 116, the first connecting surface 118 is attached to the second connecting surface 120.

In addition, the area of the second connection face 120 is smaller than or equal to the area of the first connection face 118. That is, after the first insulating frame 106 is connected to the insulator 104, the first insulating frame 106 is entirely located on the axial side of the insulator 104, and it is ensured that the first insulating frame 106 is not located on the radial side of the insulator 104.

Thus, firstly, the two-stage design of the first insulating frame 106 and the core structure 100 can be ensured, and secondly, the position of the first insulating frame 106 can be optimized, so as to provide conditions for realizing the universality of the first insulating frame 106, so that the second connecting portion 116 and the first insulating frame 106 do not need to be changed for adapting to the core structure 100.

In this embodiment, further, as shown in fig. 2 and 4, one of the first connection portion 114 and the second connection portion 116 is a convex portion, and the other of the first connection portion 114 and the second connection portion 116 is a concave portion. In this way, the first insulating frame 106 and the insulator 104 are detachable through the matching of the convex part and the concave part, and the connection mode of the first insulating frame 106 and the insulator 104 is simplified, so that the universality of the first insulating frame 106 is enhanced, the first insulating frame 106 can be used universally among different projects, and the development cycle of the motor is further shortened.

Specifically, as shown in fig. 2 and 4, the first connection portion 114 may be a concave portion, and the second connection portion 116 may be a convex portion. However, it will be understood by those skilled in the art that the first connecting portion 114 may be a convex portion and the second connecting portion 116 may be a concave portion.

In this embodiment, it is understood that the first connecting portion 114 and the second connecting portion 116 may also use a snap structure, or the like, as long as the detachable connection between the first insulating frame 106 and the insulating body 104 can be ensured, and those skilled in the art will understand that no more explanation is made herein.

In this embodiment, further, the cross-sectional shape of the convex portion may be a polygon, a circle, an ellipse, or the like, and the cross-sectional shape of the concave portion matches the cross-sectional shape of the convex portion. In this way, the convex portion and the concave portion can be matched, so that the first insulating frame 106 and the second insulating frame 108 can be fixedly connected with the iron core structure 100 without using tools, the connection mode is simplified, the second insulating frame 108 and the iron core structure 100 can be more conveniently connected and detached, the universality of the insulating frames is increased, and the development period is shortened.

In this embodiment, further, as shown in fig. 6, the convex portion and the concave portion are transition fit or interference fit. In this way, the second insulating frame 108 can be connected to the insulator 104 without using tools, which can make the connection more convenient on one hand and more firm on the other hand, thereby ensuring the reliability of operation and shortening the development period.

Further in this embodiment, as shown in fig. 2 and 4, the first insulation frame 106 includes a first winding slot 130. Wherein, the bottom wall of the first winding slot 130 (i.e. the second connection surface 120 of the first insulation frame 106) can be detachably connected with the first connection surface 118 of the insulation body 104. In this way, the first insulating frame 106 and the insulator 104 can be more conveniently connected and detached, and the versatility of the first insulating frame 106 is increased, thereby shortening the development cycle.

In particular, the first winding slot 130 is matched with the winding diameter of the motor, and the first insulating frame 106 can be used universally as long as the winding diameter in the design scheme of the motor is unchanged, and can be directly used in other design schemes, so that the running reliability of a prototype is ensured, and the development cycle of the motor is shortened.

A fourth embodiment of the present invention provides a stator assembly 10, further comprising, in addition to the first, second and third embodiments:

as shown in fig. 3 and 5, the insulator 104 is provided with a third connecting portion 122, and the second insulating frame 108 is provided with a fourth connecting portion 124. The third connecting portion 122 is disposed at the axial second end 112 of the core structure 100, and the fourth connecting portion 124 can be detachably connected to the third connecting portion 122, so as to ensure the detachable connection between the insulator 104 and the second insulating frame 108.

Specifically, as shown in fig. 3 and 5, the third connecting portion 122 is disposed on the insulator 104 and located at the second end 112 of the core structure 100 in the axial direction. In this way, after the second insulating frame 108 is connected to the insulator 104, it is ensured that the second insulating frame 108 is located at the second end 112 in the axial direction of the core structure 100, so that the second insulating frame 108 and the insulator 104 are distributed in the axial direction of the stator assembly 10, and the second insulating frame 108 is not inserted to the peripheral side of the core structure 100.

Thus, on the basis of ensuring that the second insulating frame 108 is connected with the insulator 104, the size of the whole iron core structure 100 does not need to be considered, and the size of the second insulating frame 108 does not need to be changed according to the iron core structure 100, so that the universality of the second insulating frame 108 is realized.

In this embodiment, further, as shown in fig. 3 and 5, the insulator 104 includes a third connection face 126, and the third connection portion 122 is provided on the third connection face 126. In addition, a fourth connection surface 128 is provided on the second insulating frame 108, and the fourth connection portion 124 is provided on the fourth connection surface 128.

Further, as shown in fig. 3 and 5, the area of the fourth connection face 128 is smaller than or equal to the area of the third connection face 126. That is, after the second insulating frame 108 is connected to the insulator 104, the second insulating frame 108 is entirely located on the axial side of the insulator 104, and it is ensured that the second insulating frame 108 is not located on the radial side of the insulator 104.

Thus, firstly, the two-stage design of the second insulating frame 108 and the core structure 100 can be ensured, and secondly, the position of the second insulating frame 108 can be optimized, so as to provide conditions for realizing the universality of the second insulating frame 108, so that the fourth connecting portion 124 and the second insulating frame 108 do not need to be changed for adapting to the core structure 100.

In this embodiment, further, as shown in fig. 3 and 5, one of the third connection portion 122 and the fourth connection portion 124 is a convex portion, and the other is a concave portion. In this way, the second insulating frame 108 and the insulator 104 are detachably connected through the matching of the convex part and the concave part, and the connection mode of the second insulating frame 108 and the insulator 104 is simplified, so that the universality of the second insulating frame 108 is improved, the second insulating frame 108 can be commonly used among different projects, and the development cycle of the motor is further shortened.

Specifically, as shown in fig. 3 and 5, the third connection portion 122 may employ a concave portion, and the fourth connection portion 124 may employ a convex portion. However, it will be understood by those skilled in the art that the third connecting portion 122 may be a convex portion, and the fourth connecting portion 124 may be a concave portion.

In this embodiment, further, as shown in fig. 3 and 5, the cross-sectional shape of the convex portion may be a polygon, a circle, an ellipse, or the like, and the cross-sectional shape of the concave portion matches the cross-sectional shape of the convex portion. Thus, the convex part and the concave part can be matched, the first insulating frame 106 and the second insulating frame 108 can be fixedly connected with the iron core structure 100 without using tools, the connection mode is simplified, the second insulating frame 108 and the iron core structure 100 can be more conveniently connected and detached, the universality of the second insulating frame 108 is increased, and the development period is shortened.

In this embodiment, further, as shown in fig. 3 and 5, the second insulation frame 108 includes a second winding slot 132. Wherein, the bottom wall of the second winding slot 132 (i.e. the fourth connection surface 128 of the second insulating frame 108) can be detachably connected with the third connection surface 126 on the core structure 100. Thus, the second insulating frame 108 and the insulator 104 can be more conveniently connected and detached, and the universality of the second insulating frame 108 is increased, so that the development period is shortened.

In particular, the second winding groove 132 is matched with the winding diameter of the motor, and the second insulating frame 108 can be used universally as long as the winding diameter in the design scheme of the motor is not changed, and can be directly used in other design schemes, so that the running reliability of a prototype is ensured, and the development cycle of the motor is shortened.
