Technical Field
[0001] This application relates to the technical field of motors, and particularly to an insulating skeleton, a stator, and a motor. Background Art
[0002] The insulating skeleton can insulate and support the motor winding and the iron core. The conventional insulating skeleton consists of two upper and lower insulating skeletons, and the winding is wound on the insulating skeleton. However, after the winding is completed, bulges or swellings are likely to occur on both sides of the winding, reducing the slot fill factor of the winding and affecting the performance of the motor. Moreover, in the case of a longer iron core or a longer skeleton, the bulging situation is more obvious. Summary of the Invention
[0003] This application aims to provide an insulating skeleton, a stator, and a motor to extend the distance between the skeleton body and the iron core, thereby avoiding or reducing the phenomenon of winding bulging or swelling and improving the performance of the motor.
[0004] According to the first aspect of this application, there is provided an insulating skeleton, including two skeleton bodies. The skeleton body is provided with an insulating slot. The two skeleton bodies are respectively sleeved on both ends of the iron core in the axial direction through the insulating slot. At least one side wall of the insulating slot of the skeleton body is provided with an elastic support structure. The elastic support structure has a first state of storing elastic potential energy and a second state of releasing elastic potential energy and resetting. The elastic support structure is used to abut against the side surface of the iron core in the first state. The elastic support structure is further used to move to the outside of the end surface of the iron core in the second state to extend the distance between the skeleton body and the end surface of the iron core.
[0005] As a further solution of the insulating skeleton provided by this application, the elastic support structure is further used to make the bottom of the insulating slot abut against the end surface of the iron core in the first state.
[0006] As a further solution of the insulating skeleton provided by this application, elastic support structures are provided on opposite side walls of the insulating slots of the two skeleton bodies.
[0007] As a further solution of the insulating skeleton provided by this application, the elastic support structure penetrates the skeleton body in the radial direction of the skeleton body.
[0008] As a further solution of the insulating skeleton provided by the present application, the elastic support structure is an elastic arm. The root of the elastic arm is connected to the side wall of the insulating slot near its bottom. A first abutting portion is provided on the side of the elastic arm facing away from the side wall of the insulating slot, and a second abutting portion is provided on the side of the elastic arm away from its root. In the first state, the first abutting portion abuts against the side surface of the iron core. In the second state, the second abutting portion moves to the outside of the end surface of the iron core.
[0009] As a further solution of the insulating skeleton provided by the present application, an avoidance groove is further provided on the side wall of the insulating slot. The elastic arm is arranged in the avoidance groove. In the first state, the elastic arm is received in the avoidance groove. In the second state, the elastic arm protrudes from the avoidance groove.
[0010] As a further solution of the insulating skeleton provided by the present application, it further includes a temporary guiding tooling. The temporary guiding tooling is used for detachably installing on the end surface of the iron core. The temporary guiding tooling is provided with a guiding inclined surface, and one end of the guiding inclined surface extends to the outermost side of the end surface of the iron core to guide the elastic support structure into the first state.
[0011] As a further solution of the insulating skeleton provided by the present application, the skeleton body is further provided with a first insulating plate and a second insulating plate. The first insulating plate and the second insulating plate are respectively arranged on opposite sides of the skeleton body. The space between the first insulating plate and the second insulating plate is a winding portion. An outgoing line groove is further provided on the first insulating plate or the second insulating plate.
[0012] According to the second aspect of the present application, the present application provides a stator, including an iron core, the insulating skeleton, and a winding wound around the insulating skeleton.
[0013] According to the third aspect of the present application, the present application provides a motor, including the stator and further including a rotor. The rotor is arranged on the inner peripheral side or the outer peripheral side of the stator.
[0014] According to the insulating skeleton, stator and motor of the above embodiments, when the two skeleton bodies are respectively sleeved on the opposite ends of the iron core through the insulating slots and the elastic support structure is in the first state of storing elastic potential energy, windings can be wound on the skeleton bodies to form windings. At this time, a bulging or swelling phenomenon occurs in the middle of the windings. Move the skeleton body in the opposite direction of the end of the iron core inserted along the insulating slot, so that the elastic support structure is in the second state of releasing elastic potential energy and resetting. Under the action of the windings, the skeleton body will not separate from the iron core, and the end face of the iron core abuts against the elastic support structure, so as to extend the distance between the skeleton body and the iron core, stretch the windings, and then make the bulging or swelling phenomenon disappear. In this way, the phenomenon of the windings bulging or swelling can be avoided or reduced, and the performance of the motor can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0035] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0036] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are essential components and / or sequences.
[0037] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).
[0038] The stator generally consists of two upper and lower insulating skeletons, an iron core located in the middle, and windings wound on the insulating skeletons. The upper insulating skeleton and the lower insulating skeleton are respectively inserted into the ends of the iron core from both ends in the axial direction of the iron core, and then the windings are wound on the upper insulating skeleton and the lower insulating skeleton to form the stator. Due to the uneven tension during winding, the windings on both sides of the middle part of the iron core are looser than the windings at both ends in the axial direction of the iron core after winding. Therefore, it is easy for the windings on both sides in the radial direction of the iron core to bulge or swell. At the same time, the longer the length of the iron core or the insulating skeleton, the more obvious the bulging situation, which reduces the slot filling factor of the windings and affects the performance of the motor.
[0039] See Figures 1 - 14 As shown, the insulating skeleton provided in this embodiment includes two skeleton bodies 10. The skeleton body 10 is provided with an insulating slot 11. The two skeleton bodies 10 are respectively sleeved on both ends in the axial direction of the iron core 20 through the insulating slot 11. At least one side wall of the insulating slot 11 of the skeleton body 10 is provided with an elastic support structure 12. The elastic support structure 12 has a first state of storing elastic potential energy and a second state of releasing elastic potential energy and resetting. It should be noted that the elastic support structure 12 can be deformed under the action of an external force to store elastic potential energy, and when the external force is eliminated, the elastic support structure 12 releases elastic potential energy and resets.
[0040] Specifically, the elastic support structure 12 is used to abut against the side surface of the iron core 20 in the first state (as Figure 5 shown). In other words, in the first state, the side surface of the iron core 20 fits against the elastic support structure 12. The elastic support structure 12 is also used to move to the outside of the end surface of the iron core 20 in the second state (as Figure 6 shown) to extend the distance between the skeleton body 10 and the end of the iron core 20.
[0041] It should be noted that the elastic support structure 12 in the second state is in a state where the skeleton body 10 is stretched outward to the outside of the end face of the iron core 20, thereby releasing elastic potential energy and resetting. At this time, the elastic support structure 12 in the second state may or may not contact the end face of the iron core 20.
[0042] It can be understood that when the radial size of the iron core 20 is basically equal to the radial size of the insulation slot 11, the elastic support structure 12 in the first state can be in contact with the side surface of the iron core 20. When the elastic support structure 12 is in the second state, the elastic support structure 12 moves to the outside of the end face of the iron core 20, thereby extending the distance between the skeleton body 10 and the end face of the iron core 20.
[0043] The two skeleton bodies 10 are respectively slidably sleeved on both ends of the iron core 20 in the axial direction through the insulation slots 11. In other words, the two skeleton bodies 10 can reciprocally slide relative to both ends of the iron core 20 in the axial direction. The elastic support structure 12 has a first state in which it can be compressed to store elastic potential energy and a second state in which it releases elastic potential energy and resets. During the process of sleeving the skeleton body 10 on the end of the iron core 20 through the insulation slot 11, before the side surface of the iron core 20 contacts the elastic support structure 12, an external force can be used to make the elastic support structure 12 be compressed and deformed. After the side surface of the iron core 20 contacts the elastic support structure 12, the elastic support structure 12 can be continuously kept in a compressed and deformed state through the side surface of the iron core 20 until the side surface of the iron core 20 abuts against the elastic support structure 12, so that the elastic support structure 12 stores elastic potential energy in the first state. When the skeleton body 10 is moved in the opposite direction along the insulation slot 12 inserted onto the iron core 20 and the elastic support structure is in the second state of releasing elastic potential energy and resetting, the end face of the iron core 20 moves to the outside of the elastic support structure 12, causing the insulation slot 11 to separate from the iron core 20, thereby extending the distance between the skeleton body 10 and the end of the iron core 20, and making the elastic support structure 12 be in the second state of releasing elastic potential energy and resetting. When the elastic support structure 12 is in the second state, the skeleton body 10 can also be continuously moved to be separated from the iron core 20.
[0044] It should be noted that during installation, when the skeleton body 11 is inserted into the iron core 20 through the insulation slot 12 along one end until the elastic support structure 12 contacts the end face of the iron core 20, the elastic support structure 12 is located outside the end face of the iron core 20. During this period, the elastic support structure 12 is not affected by an external force, corresponding to the initial state of the elastic support structure. When the elastic support structure 12 is elastically deformed under the action of an external force and the elastic support structure 12 abuts against the side surface of the iron core 20 in the state of moving the skeleton body 11, the elastic support structure 20 is in the first state to store elastic potential energy.
[0045] Combined Figures 15 - 18 As shown, when two skeleton bodies 10 are respectively sleeved at both ends in the axial direction of the iron core 20 through the insulating slots 12, and the elastic support structure 12 is in the first state, windings can be wound on the skeleton bodies 10 to form a winding 100. Under the action of the winding force of the winding 100, the bottom of the insulating slot 11 can be abutted against the end face of the iron core 20, as Figure 15 and Figure 16 shown. The figure shows a schematic diagram of the elastic support structure 12 in the first state. At this time, a bulge or swelling phenomenon occurs in the middle of the winding 100, as Figure 17 and Figure 18 shown. Move the skeleton body 10 in the opposite direction of both ends in the axial direction of the iron core 20 along the insulating slot 12, so that the elastic support structure 12 is in the second state of releasing elastic potential energy and resetting. Under the action of the winding 100, the skeleton body 10 will not break away from the iron core 20, and the end face of the iron core 20 is abutted against the elastic support structure 12, so as to extend the distance between the skeleton body 10 and the iron core 20, stretch the winding 100, and further make the bulge or swelling phenomenon disappear. In this way, the phenomenon of the winding 100 generating a bulge or swelling can be avoided or reduced, and the performance of the motor can be improved accordingly.
[0046] Specifically, at least one elastic support structure 12 can be arranged in the insulating slot 11 of one of the skeleton bodies 10 (as Figure 6 shown). Of course, elastic support structures 12 can also be arranged on the opposite two side walls in the insulating slots 11 of the two skeleton bodies 10. Both methods can meet the purpose of changing the distance between the skeleton body 10 and the iron core 20. Of course, when choosing to arrange one or two elastic support structures 12 on one of the skeleton bodies 10 or on both of the two skeleton bodies 10, it is specifically determined by the distance to be changed and the strength of the elastic support structure 12, which will not be elaborated here.
[0047] As Figures 1 - 3 , Figures 5 - 14 , Figure 16 and Figure 18 shown, in this embodiment, the elastic support structure 12 is arranged on the side wall of the insulating slot 11 close to its bottom.
[0048] Of course, in other embodiments, the elastic support structure 12 can also be arranged at other positions on the side wall of the insulating slot 11, as long as it can meet the requirement of abutting against the end face of the iron core 20 in the second state, and it is specifically determined according to the size of the distance to be changed between the skeleton body 10 and the end face of the iron core 20.
[0049] In this embodiment, elastic support structures 12 are provided on opposite side walls of the insulating slot 11 , so that the elastic support structures 12 in the second state can provide a more uniform stress state for the end surface of the iron core 20 to abut against the elastic support structures 12 .
[0050] like Figure 1 and Figure 2 As shown, the elastic support structure 12 penetrates the skeleton body 10 in the radial direction of the skeleton body 10, which can make the force area acting on the end of the core 20 larger, ensuring that the elastic support structure 12 in the second state can provide a more stable limit for the core 20.
[0051] like Figure 2 , Figure 8 , Figure 10 , Figure 12 , Figure 14 As shown, the elastic support structure 12 is an elastic arm 121, the root of the elastic arm 121 is connected to the side wall of the insulating slot 11 close to the bottom of the slot, the side of the elastic arm 121 away from the side wall of the insulating slot 11 is provided with a first abutting portion 122, and the side of the elastic arm 121 away from the root is provided with a second abutting portion 123, wherein the root of the elastic arm 121 is the connection between the elastic arm 121 and the side wall of the insulating slot 11. In the first state, the first abutting portion 122 abuts against the side of the iron core 20, and in the second state, the second abutting portion 123 can abut against the end face of the iron core 20 under the action of the winding wound on the skeleton body 10.
[0052] like Figure 1 , Figures 3 - 7 , Figure 9 , Figure 11 , Figure 13 as well as Figures 15 - 18 As shown, in order to facilitate the winding of the winding 100, the frame body 10 of the insulating frame provided in this embodiment is further provided with a first insulating plate 13 and a second insulating plate 14, wherein the first insulating plate 13 and the second insulating plate 14 are respectively arranged on opposite sides of the frame body 10, and the space between the first insulating plate 13 and the second insulating plate 14 is a winding portion 15 (such as Figure 1 As shown), the winding 100 can be wound on the winding portion 15, and the winding 100 can be limited by the first insulating plate 13 and the second insulating plate 14 to prevent the winding 100 from shifting.
[0053] In this embodiment, a wire outlet slot 141 is further provided on the first insulating plate 13 or the second insulating plate 14 to lead out the winding 100. After the insulating frame and the iron core 20 are combined to form a stator, the second insulating plate 14 is the side facing the outside of the stator, so the wire outlet slot 141 is preferably provided on the second insulating plate 14.
[0054] like Figure 2, Figure 10 , Figure 12 , Figure 14 As shown in Figure 10 , Figure 12 , and Figure 14 , in the insulating skeleton provided in this embodiment, an avoidance groove 111 is further provided on the side wall of the insulating slot 11, and the elastic arm 121 is disposed in the avoidance groove 111. In the first state, the elastic arm 121 is compressed by an external force and accommodated in the avoidance groove 111, and then can abut against the side surface of the iron core 20. In the second state, the elastic arm 121 releases elastic potential energy and is in a reset state protruding from the avoidance groove 111, and the elastic arm 121 moves to the outside of the end surface of the iron core 20, so that the elastic arm 121 in the second state abuts against the end surface of the iron core 20 under the action of the winding 100 wound on the skeleton body 10.
[0055] For facilitating the application of a force to the elastic support structure 12 during the assembly process, refer to Figures 9 - 14 As shown in Figures 9 - 14 , the insulating skeleton provided in this embodiment further includes a temporary guiding tooling 30, which is used for detachably installing at the end of the iron core 20. The temporary guiding tooling 30 is provided with a guiding inclined surface 31, and one end of the guiding inclined surface 31 extends to the outermost side of the end surface of the iron core 20 to guide the elastic support structure 12 into the first state, that is, to make the side surface of the iron core 20 abut against the side surface of the elastic support structure 12, so that the elastic support structure 12 enters the first state from the initial state.
[0056] In this embodiment, the length of the temporary guiding tooling 30 is substantially equal to the length between the opposite side walls of the insulating slot 11, and the opposite side walls of the insulating slot 11 are the two side walls where the elastic support structure 12 is provided. Specifically, refer to Figure 9 and Figure 10 As shown in Figure 9 and Figure 10 , when the skeleton body 10 is sleeved on the iron core 20 through the insulating slot 11, the state where the guiding inclined surface 31 contacts the elastic support structure 12 is shown. Refer to Figure 11 and Figure 12 As shown in Figure 11 and Figure 12 , as the skeleton body 10 continues to move, the guiding inclined surface 31 can apply a force to the elastic support structure 12 under the action of the temporary guiding tooling 30, so that the elastic support structure 12 deforms towards the avoidance groove 11. Refer to Figure 13 and Figure 14 As shown in Figure 13 and Figure 14 , continue to move the skeleton body 10 until the side surface of the iron core 20 contacts the elastic support structure 12, and the elastic support structure 12 can be deformed and accommodated in the avoidance groove 11.
[0057] As Figure 1As shown, the insulating slot 11 has opposite side walls 112 and opposite side openings 113. The two side walls 112 can enclose the insulating slot 11. The two side openings 113 are located between the opposite two side walls 112. The positions where the two side openings 113 are provided are the two ends where the elastic support structure 12 extends in the radial direction of the skeleton body 10. The temporary guiding tooling 30 is used to be slidably inserted into the end of the iron core 20. When the elastic support structure 12 is in the first state, the temporary guiding tooling 30 can be slid out of the side opening 12 of the insulating slot 11 through the insulating slot 11 in a sliding manner.
[0058] This embodiment also provides a stator, including the insulating skeleton in the above embodiment, and further including an iron core 20, the insulating skeleton in any of the above embodiments, and windings wound around the insulating skeleton.
[0059] This embodiment also provides a motor, including the stator in the above embodiment, and further including a rotor, wherein the rotor is arranged on the inner peripheral side or the outer peripheral side of the stator to form a motor.
[0060] In summary, in the insulating skeleton, stator, and motor provided by this application, when the two skeleton bodies are respectively sleeved on the opposite ends of the iron core through the insulating slots and the elastic support structure is in the first state of storing elastic potential energy, windings can be wound around the skeleton bodies to form windings. At this time, a bulging or swelling phenomenon occurs in the middle of the windings. Move the skeleton body in the opposite direction of inserting into the end of the iron core along the insulating slot. Under the action of the windings, the skeleton body will not separate from the iron core, and the end face of the iron core abuts against the elastic support structure, so as to extend the distance between the skeleton body and the iron core, stretch the windings, and thus the bulging or swelling phenomenon can disappear. In this way, the phenomenon of the windings bulging or swelling can be avoided or reduced, and the performance of the motor can be improved.
