[0001] This application is based on a Chinese patent application filed with the China Patent Office on May 17, 2021, bearing application number 202110536646.1 and titled "Insulating framework, stator, motor, compressor and vehicle," and a Chinese patent application filed with the China Patent Office on May 17, 2021, bearing application number 202121052696.4 ... Priority is claimed from a Chinese patent application filed with the Patent Office on May 17, 2021, bearing application number 202110534784.6 and entitled "Insulating framework, stator, motor, compressor and vehicle," and a Chinese patent application filed with the Patent Office on May 17, 2021, bearing application number 202121051945.8 and entitled "Insulating framework, stator, motor, compressor and vehicle," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of compressor technology, and more particularly to an insulating framework, a stator, a motor, a compressor, and a vehicle. [Background technology]

[0003] Currently, motors include a stator and a rotor, where the rotor and stator are configured as laminated cores, with a coil wound around each individual tooth in the stator slot. The coil is usually wound around a stator core, and there is an insulating framework between the stator core and the coil to insulate the coil.

[0004] In order to reduce the volume of the compressor and increase the operating range of the compressor, the motor not only needs to achieve high power density, but also needs to minimize the height of the core at the same output power, and at the same time, the winding of the motor coil around the insulating framework needs to be as compact as possible to improve the space factor of the stator. However, the insulating framework in the related art does not have a corresponding structural part that can be effectively engaged when fixing the coil lead wire, which reduces the fixation of the coil.

[0006] Thus, a first aspect of the present application provides an insulating framework.

[0007] A second aspect of the present application further provides a stator.

[0008] A third aspect of the present application further provides a motor.

[0009] A fourth aspect of the present application further provides a compressor.

[0010] A fifth aspect of the present application further provides a vehicle.

[0011] A sixth aspect of the present application provides an insulating framework.

[0012] A seventh aspect of the present application further provides a stator.

[0013] An eighth aspect of the present application further provides a motor.

[0014] A ninth aspect of the present application further provides a compressor.

[0015] A tenth aspect of the present application further provides a vehicle. [Means for solving the problem]

[0016] In view of this, a first aspect of the present application provides an insulating framework, including a first support, a second support installed opposite the first support, a wire slot formed in the second support, the wire slot penetrating a wall surface of the second support, a portion of the bottom wall of the wire slot inclined toward the bottom of the second support to form a sloped portion, the sloped portion being located on the side of the wire slot facing the first support, and a third support located between the first support and the second support and connected to the first support and the second support.

[0017] The insulating framework provided herein includes a first support, a second support, and a third support, where the second support and the first support are disposed opposite to each other, and the third support is disposed between the first support and the second support, with one end of the third support connected to the first support and the other end of the third support connected to the second support, thereby connecting the first support, the second support, and the third support together. The second support has a wire slot, which includes a bottom wall, and the bottom wall of the wire slot is inclined toward the bottom of the second support, forming an inclined portion, where the inclined portion is located on the side closer to the first support. When a wire is wound around the insulating framework, the coil extends from the side of the wire slot away from the first support into the wire slot and then extends along the inclined portion to the bottom of the first support, thereby facilitating coil winding. Furthermore, the wire slot can pre-fix the coil, making the coil winding more compact, improving coil fixation and increasing the space factor of the stator core.

[0018] In a specific application, the insulating framework is applied to a stator, which includes a stator core, a coil, and the insulating framework, where the insulating framework is installed at both axial ends of the stator core, and the coil is wound around the insulating framework and the stator core. The first support, the second support, and the third support together surround a winding receiving portion for receiving the coil, and the stator core is pulled through the wire slot, so that the coil is inclined downward along the inclined portion, and the coil is wound more tightly.

[0019] Specifically, the first support, the second support, and the third support are integrally molded.

[0020] As can be understood, the wire slot includes an opening and a bottom wall facing the opening, a portion of the bottom wall of the wire slot is inclined toward the bottom of the second support to form a slope, and the slope is located on the side of the wire slot facing the first support, i.e., the slope is located inside the first support. That is, the upper half of the wire slot is approximately U-shaped, the opening is located at the top of the U, and the lower half of the wire slot is sloped, which makes the coil more compact when passing through and improves the fixation of the coil winding.

[0021] Specifically, when the insulating framework is applied to a stator, the first support is close to the inside of the stator core, the second support is close to the outside of the stator core, and the third support is connected to and located between the first support and the second support.

[0022] According to the above insulating framework provided in the present application, it can have the following additional technical features:

[0023] In the above technical means, the insulating framework further includes a terminal accommodating portion provided on a side of the second support away from the first support, used to accommodate a crimp terminal, and located on a first side of the wire slot along the first direction.

[0024] In this technical solution, the insulating framework further includes a terminal accommodating portion, the terminal accommodating portion is mounted on the second support, and a crimp terminal is mounted in the terminal accommodating portion. The coils of the same phase are connected in series by the crimp terminal in the terminal accommodating portion. Here, the terminal accommodating portion is mounted on the side of the second support away from the first support, thereby avoiding occupancy of the coil winding space. At the same time, the terminal accommodating portion and the wire slots are distributed along the first direction, facilitating coil winding and series connection of the coils of the same phase. Furthermore, by providing the terminal accommodating grooves in the insulating framework, it is possible to avoid overlapping other structures realizing the same-phase electrical connection above the insulating framework, further reducing the overall size of the stator.

[0025] Here, the first direction is the circumferential direction of the stator core.

[0026] In any of the above technical means, the terminal accommodating portion further includes an accommodating groove, which is used to accommodate a crimp terminal, and which has a notch formed in the accommodating groove, the notch being located on a side wall of the accommodating groove along a first direction, and adhesive overflow grooves which are located on both sides of the accommodating groove along the first direction and communicate with the notch.

[0027] In this technical solution, the terminal accommodating portion includes an accommodating groove and an adhesive overflow groove, and the accommodating groove is used to accommodate the crimp terminal of the stator, wherein a notch is provided in the accommodating groove, and the winding start and end portions of the in-phase coil extend from the notch on one side of the accommodating groove into the accommodating groove, which plays a positioning role for the coil and ensures the stability of the coil, while at the same time realizing the electrical connection of the in-phase coil by the crimp terminal.

[0028] In addition, adhesive overflow grooves are installed on both sides of the accommodating groove and communicate with the notch. In this way, after the same-phase coils are electrically connected by the connecting terminals, the coils are sealed with sealant in the accommodating groove and notch, improving the safety performance of the coil. Furthermore, by installing the adhesive overflow grooves, excess sealant is caught in the adhesive overflow groove during the process of sealing the crimp terminal with sealant, so that the sealant does not overflow outside the terminal accommodating portion and achieves good sealing of the coil.

[0029] In a specific application, the receiving groove has two notches, and the two notches are respectively disposed on two side walls of the receiving groove in the first direction. Similarly, the number of adhesive overflow grooves is two, and the two adhesive overflow grooves are disposed corresponding to the two notches, so that when sealing the two notches, the adhesive overflow grooves can be prevented from overflowing from either of the two notches.

[0030] As can be seen, when a low-viscosity sealant is used to seal the crimp terminal and the cutout section of the conductor, the sealant tends to flow down the side walls of the receiving groove, making it difficult to completely seal the crimp terminal and the cutout section of the conductor. When a high-viscosity sealant is used, the sealant does not flow well and the notch of the receiving groove is narrow, making it very difficult to completely cover the crimp terminal and the cutout section of the conductor. Therefore, the present application provides an adhesive overflow groove to prevent the sealant from overflowing and ensure a complete seal of the crimp terminal and the cutout section of the coil conductor.

[0031] In any of the above technical means, the terminal accommodating portion further includes an adhesive overflow pad provided on both sides of the accommodating groove along the first direction, and a boss provided on the adhesive overflow pad, at least the boss surrounding the adhesive overflow groove together with the adhesive overflow pad.

[0032] In this technical solution, the terminal accommodating portion further includes an adhesive overflow pad and a boss, and the adhesive overflow pads are installed on both sides of the accommodating groove, i.e., the terminal accommodating portion has adhesive overflow pads protruding on both sides in the first direction of the accommodating groove. When the boss is installed on the adhesive overflow pad, at least the adhesive overflow pad and the boss surround the adhesive overflow groove, and the adhesive overflow groove surrounds at least a portion of the notch. Furthermore, when sealant is poured into the accommodating groove and the notch to seal, excess sealant can flow into the adhesive overflow groove, preventing the sealant from overflowing from the terminal accommodating portion.

[0033] As will be appreciated, the crimp terminals penetrate the coils, thereby connecting the in-phase coils.

[0034] In a specific application, the crimp terminal is a break-through terminal, so that when the crimp terminal is pressed against the coil in the receiving groove, it can break through the insulating coating on the coil surface, thereby realizing electrical connection of the coils in the same phase and realizing quick connection.

[0035] In any of the above technical means, the boss further includes a first boss provided on the side of the accommodating groove away from the wire slot and located on the side of the notch away from the first support, and a second boss provided on the side of the accommodating groove closer to the wire slot, surrounding the adhesive overflow groove together with the second support and the accommodating groove, and having a notch between it and the accommodating groove.

[0036] In this technical solution, the boss includes a first boss and a second boss, and the first boss and the second boss are respectively installed on adhesive overflow pedestals on both sides of the accommodating groove, wherein the first boss is installed on the side of the accommodating groove away from the wire slot and is located on the side of the notch away from the first support, so that when sealant is injected into the accommodating groove and the notch, excess sealant is received by the first boss, preventing the sealant from overflowing.

[0037] The second boss is installed on the side of the receiving groove closer to the wire slot, and the second boss surrounds the adhesive overflow groove together with the surface of the second support and the outer wall surface of the receiving groove, where the area between the end of the second boss and the wall surface of the receiving groove is not completely closed but has a notch, thereby facilitating cutting and sealing of the end of the coil winding.

[0038] In a specific application, a routing slot is provided at the bottom of the first boss, and the routing slot is positioned opposite the notch, so that the coil can be further fixed within the routing slot and the robustness of the coil can be improved.

[0039] Furthermore, the size of the notch is small, which further prevents the sealant from leaking out. Specifically, the width of the notch is 1 mm or more and 5 mm or less.

[0040] In any of the above technical means, the notch further includes a first passage and a second passage that communicate with each other, the first passage is located at the top of the second passage, and the side walls of the first passage are arranged to gradually widen on both sides of the first passage.

[0041] In this technical solution, the notch includes a first passage and a second passage that communicate with each other, i.e., the notch is divided into an upper half and a lower half, wherein the first passage is located in the upper half and the second passage is located in the lower half, the upper and lower halves are connected, and the side walls of the first passage are arranged to gradually widen, making it easy to pass the coil through the notch. At the same time, the upper half of the notch is arranged at an angle, making it easy to inject the sealant, and the sealant can flow along the angled wall surfaces toward the bottom of the slot in the notch, improving the sealing effect of the sealant on the cut cross section of the coil.

[0042] In a specific application, the notch is generally U-shaped, the sidewall of the first passage is beveled, and the sidewall of the first passage is generally flat.

[0043] In any of the above technical means, the width of the wire slot is further greater than the width of the notch.

[0044] In this technical solution, both the beginning and end of the coil are placed in the notch, making it easier for the coil to enter the slot, and because the width of the wire slot is larger than the width of the notch, the beginning and end of the coil are more tightly connected to the notch when entering the notch, improving the fixation of the notch to the coil.

[0045] In a specific application, the width of the wire slot is the width of the wire slot along the first direction, and the width of the notch is the width of the notch along the second direction. Specifically, the wire slot and the notch are both approximately U-shaped, and the width of the wire slot and the width of the notch are the distance between the left and right sidewalls of the U-shape.

[0046] By setting the width of the notch and the wire slot, the start and end of the coil can be accommodated simultaneously within the notch, while improving the compactness of the coil.

[0047] In any of the above technical means, the insulating framework further includes a protrusion provided on a side of the second support away from the first support and positioned on a second side of the wire slot along the first direction.

[0048] In this technical solution, the insulating framework further includes a protrusion, which is installed on the second support and located on a side of the second support away from the first support and the third support, and the protrusion, the wire slot and the terminal accommodating portion are sequentially installed along the first direction, and the installation of the protrusion can play a role in regulating the position of the coil and prevent the coil from slipping out, specifically, the installation of the protrusion can prevent the end of the coil from slipping out and improve the fixation of the coil.

[0049] Specifically, one coil is wound around each split core, and each coil includes a winding start portion and a winding end portion. After winding is complete, the winding end portion extends from the bottom of the protrusion into the wire slot, and the position of the coil is regulated by the wire slot.

[0050] As can be understood, along the first direction, the wire slot includes a first side and a second side, and the first side of the wire slot and the second side of the wire slot are oppositely disposed opposite sides of the wire slot, where the side of the wire slot closer to the terminal accommodating portion is the first side of the wire slot, and the side of the wire slot closer to the protrusion is the second side of the wire slot.

[0051] In any of the above technical means, at least a part of the top wall of the protrusion is further inclined toward the bottom of the second support.

[0052] In this technical solution, at least a portion of the top wall of the protrusion is inclined toward the bottom of the second support, thereby reducing the material used for the protrusion and reducing production costs, while avoiding interference with other structures when the insulating framework is used in combination with other structures.

[0053] In a specific application, the cross section of the protrusion is generally triangular.

[0054] In a specific application, a motor includes a stator core, an insulating framework, and an insulating cover plate, the insulating framework being installed on both ends of the stator core, and the insulating cover plate being installed on both ends of the insulating framework away from the stator core. The insulating cover plate serves an insulating role and improves the safety performance of the motor. Here, the protrusions engage with the insulating cover plate to connect the insulating framework and the insulating cover plate, improving the reliability of the connection between the insulating cover plate and the insulating framework.

[0055] As will be appreciated, both the insulating cover plate and the insulating framework are made of insulating material.

[0056] In any of the above technical means, furthermore, a surface of the protrusion close to the bottom of the second support is located on a side of the bottom wall of the wire slot away from the bottom of the second support.

[0057] In this technical solution, the surface of the protrusion close to the bottom of the second support is located on the side of the bottom wall of the wire slot that is away from the bottom of the second support. With this arrangement, the surface of the protrusion close to the bottom of the second support is higher than the bottom wall of the wire slot, i.e., the bottom wall of the wire slot is lower than the underside of the protrusion. Furthermore, the end of the coil is wound into the wire slot from the side of the protrusion that is away from the wire slot, which prevents the coil from bending in the wire slot and makes the coil routing more tightly.

[0058] Specifically, the difference in distance between the lower surface of the protrusion and the bottom wall of the wire slot is equal to or greater than the diameter of the conductor wire in the coil. As will be understood, a single conductor wire is wound around a split core and an insulating framework to form a coil.

[0059] In any of the above technical means, furthermore, the length by which the terminal accommodating portion protrudes from the second support body is greater than the length by which the protruding portion protrudes from the second support body.

[0060] In this technical solution, the terminal accommodating portion and the protruding portion both protrude from the second support away from the first support, and the protruding length of the protruding portion from the second support is shorter than the protruding length of the terminal accommodating portion from the second support. In this way, when the insulating framework is connected to the insulating cover plate, interference with the connection between the two is avoided, and the connection reliability between the two is ensured.

[0061] As can be seen, the second support, the third support and the first support are sequentially distributed along the second direction, and the length of the protrusion along the second direction is smaller than the length of the terminal accommodating portion.

[0062] As will be understood, the second direction is the radial direction of the stator core.

[0063] In any of the above technical means, the insulating framework may further include a stepped portion provided on the second support and located on a side of the protrusion away from the wire slot.

[0064] In this technical solution, the insulating framework further includes a stepped portion, which is attached to the second support and used to support the coil, specifically, the stepped portion is used to support the end of the coil winding, thereby improving the tightness of the coil winding.

[0065] Specifically, the step portion is located on the side of the protrusion away from the wire slot, and thus the end of the coil is wound from the top surface of the step portion below the protrusion and further extends into the wire slot, which fixes the end of the coil.

[0066] In any of the above technical solutions, the third support may further include a plurality of auxiliary slots, each of which extends along a first direction and the plurality of auxiliary slots are distributed along a second direction, with the first support, the third support, and the second support being sequentially distributed along the second direction.

[0067] In this technical solution, auxiliary slots are provided on the third support, and the number of the auxiliary slots is plural, and the coil is fixed by the auxiliary slots to improve the tightness and stability of the coil winding, wherein each auxiliary slot extends along a first direction, and the plural auxiliary slots are distributed in an array along a second direction, and the coil is wound on the insulating framework by the auxiliary slots.

[0068] Specifically, the auxiliary slot is installed on the upper surface of the third support, and when the auxiliary slot naturally extends along the outer surface of the third support, it is cut directly and flat by the side surface of the third support.

[0069] In any of the above technical means, furthermore, an edge of the inclined portion close to the bottom of the second support is substantially flush with the slot bottom of the auxiliary slot.

[0070] In this technical solution, the edge of the inclined portion near the bottom of the second support is substantially flush with the slot bottom of the auxiliary slot, which prevents bending of the coil and ensures tightness of the coil winding.

[0071] As will be understood, the edge of the ramp that is closest to the bottom of the second support is the lower edge of the ramp, and the lower edge of the ramp is generally flush with the slot bottom of the auxiliary slot, i.e., the lower edge of the ramp is flush with the slot bottom of the auxiliary slot, or the lower edge of the ramp is slightly higher than the slot bottom of the auxiliary slot.

[0072] In any of the above technical means, furthermore, a wall surface of the wire slot close to the terminal accommodating portion is substantially flush with a wall surface of the third support close to the wire slot.

[0073] In this technical solution, the wall surface of the wire slot near the terminal accommodating portion is approximately flush with the wall surface of the third support near the wire slot, and thus when the coil is wound from the wire slot to the third support, the coil can be wound more tightly, improving the space factor of the stator core.

[0074] As will be understood, the wall surface near the terminal accommodating portion of the wire slot is approximately flush with the wall surface near the wire slot of the third support, i.e., the wall surface near the accommodating portion of the wire slot is flush with the wall surface near the wire slot of the third support, or there is a minute pitch between the wall surface near the accommodating portion of the wire slot and the wall surface near the wire slot of the third support.

[0075] In any of the above technical means, a cutout is further provided on the side of the first support facing the second support, the cutout is located close to the bottom of the first support, and the cutout is located on both sides of the third support along the first direction.

[0076] In this technical solution, a notch is provided in the first support, and the notch is located inside the first support, allowing the coil winding to escape and ensuring the tightness of the coil winding.

[0077] Specifically, the notch is located on the side of the first support facing the second support and is installed close to the bottom of the first support; and further, along the first direction, the notch is installed on both sides of the third support, which not only further reduces the overall weight of the insulating framework and reduces production costs, but also prevents the third support from excessively pressing on the coil and affecting the winding of the coil.

[0078] In a specific application, the wall surface of the first support facing the second support is generally flat, and the wall surface of the first support facing away from the second support is arc-shaped. When the insulating framework is applied to a stator, the first support can be circular to accommodate the shape of the stator teeth, further facilitating rotor installation and movement. At the same time, the cutouts allow the shape of the first support to fit the end of the stator teeth facing the inside of the stator, increasing the space factor of the stator and simultaneously making the overall connection tighter.

[0079] Specifically, the notch is a flat, non-through structure.

[0080] In any of the above technical means, furthermore, the side of the notch closer to the top of the first support is flush with the top of the auxiliary slot.

[0081] In this technical solution, the side of the notch near the top of the first support is flush with one side of the top of the auxiliary slot, which further ensures the relief effect of the notch on the coil and increases the space factor of the stator.

[0082] In any of the above technical means, the insulating framework may further include a mark provided on at least one of the second support and the first support, the mark corresponding to the width of the notch in the terminal accommodating portion and the width of the auxiliary slot in the third support.

[0083] In this technical solution, the insulating framework further includes marks set on at least one of the second support and the first support, which, as can be understood, correspond to different coil diameters, different auxiliary slot widths, and different notch widths when winding different stators. That is, the coil diameter corresponds one-to-one to the notch width and the auxiliary slot width, and therefore the coil diameter changes synchronously with the notch width and the auxiliary slot width. Therefore, the technical solution proposed by the present application sets marks on the insulating framework, which correspond one-to-one to the coil diameter, notch width, and auxiliary slot width. In this way, different insulating frameworks can be selected according to the marks based on different coil diameters. Specifically, different insulating frameworks correspond to different sized notch widths and auxiliary slot widths, so that insulating frameworks with various dimensional specifications can be adapted to coils of different sizes.

[0084] Specifically, the width of the notch and the yoke width of the auxiliary slot have various dimensions, which can be selected and used according to the actual situation.

[0085] Specifically, the mark may be a number, an alphabet, or a symbol having an equivalent function.

[0086] In a specific application, the mark is placed on the terminal receiving portion of the second support, and the mark is placed on the top of the terminal receiving portion so that the user can easily recognize it.

[0087] According to a second aspect of the present application, a stator is further provided, which includes a stator core including a plurality of split cores connected in series, each split core including a tooth portion, and the tooth portions of two adjacent split cores together surrounding a stator slot; an insulating framework as provided in any one of the first aspects, in which there are a plurality of insulating frameworks, each of which is provided at both ends of one of the split cores, and a third support is installed opposite the tooth portion; and a winding wound around the tooth portion and the insulating framework.

[0088] The stator provided in the second aspect of the present application includes the insulating framework proposed by any of the technical solutions of the first aspect, and therefore has all the beneficial effects of the insulating framework.

[0089] The stator further includes a stator core, which includes a plurality of sequentially connected split cores, each split core including a tooth portion, and a stator slot for accommodating windings, which is enclosed between the teeth of two adjacent split cores, and an insulating framework is installed at both ends of each split core, allowing the windings to be wound around the tooth portion and the insulating framework, ensuring insulation performance. At the same time, this winding method allows the windings to be electrically connected to the insulating framework alone, eliminating the need for other structures to achieve electrical connection, further reducing the axial height of the stator and making the end of the stator more compact.

[0090] In any of the above technical means, the winding further includes a plurality of coils, one coil wound around one split core and insulating frameworks at both ends of the split core, the coil including a winding start portion and a winding end portion, and the wire slots are used to accommodate the winding start portion and the winding end portion.

[0091] In this technical solution, the winding includes multiple coils, and one split core and an insulating framework at both ends thereof constitute one core component, in which one coil is wound on each core component, and after the winding of each coil is completed, the multiple core components are rolled up to form a stator, which further improves the space factor and prevents scratches on the insulating layer on the coil surface.

[0092] Here, the coil includes a start portion and an end portion, and wire slots are used to accommodate the start portion and the end portion to ensure tightness of the coil winding.

[0093] Specifically, the winding start portion is engaged in the wire slot at one end of the stator core in the axial direction and extends to the other end of the stator core, and winding begins on the side of the insulating framework far from the wire slot, and the winding end portion is located on the side of the insulating framework close to the wire slot, and then the winding end portion is wound around the step portion, extends over the upper surface of the step portion to below the protrusion, and then extends into the wire slot and is pre-fixed in the wire slot. After all the coils have been wound, the multiple split cores are rolled to form the stator. Compared to the prior art, the technical solution proposed in this application not only improves the space factor of the stator, but also prevents damage to the insulation layer of the coil itself.

[0094] In any of the above technical means, the stator further includes an insulating cover plate that is disposed on a side of the insulating framework away from the stator core and that engages with the protrusions of the insulating framework.

[0095] In this technical solution, the insulating framework further includes an insulating cover plate installed on the side of the insulating framework away from the stator core, and the installation of the insulating framework can realize rounded insulation protection for both ends of the coil and improve the safety performance of the stator. Here, the insulating cover plate is connected to the protrusions of the insulating framework to realize the fixing of the insulating cover plate, making the overall structure of the stator more compact and achieving effective engagement between the two.

[0096] Additionally, the insulating cover plate engages the projections of the insulating framework.

[0097] In a specific application, a snap is installed on the insulating cover plate, and the snap engages with the protrusion. As can be understood, the length of the protrusion is shorter than the length of the terminal receiving part, so that the engagement between the snap and the protrusion is guaranteed.

[0098] Furthermore, any of the split cores includes a plurality of stamped pieces that are stacked and distributed along the axial direction of the stator core.

[0099] In this technical solution, each split core is configured to include a plurality of punched pieces that are stacked and distributed along the axial direction of the stator core, and overlapping portions are formed on the peripheral edges of the punched pieces. When the plurality of punched pieces are stacked and distributed along the axial direction of the core, overlapping gaps are limited between adjacent punched pieces and are formed in the stator slots, making it easy for the windings to be wound around the teeth of the stator core and located within the stator slots.

[0100] Specifically, the punched piece is a silicon steel plate.

[0101] Furthermore, two adjacent split cores are rotatably connected by an overlapping portion.

[0102] In this technical solution, two adjacent split cores are rotatably connected by an overlapping portion, that is, the two connected split cores are rotatable relative to each other.

[0103] By connecting two adjacent split cores rotatably through an overlapping portion, one split core can be rotated around the other split core, with the connection point of the overlapping portion as the center of the circle. This connection method is simple and reliable, and allows the operator to easily adjust the outer shape and structure of the stator core, and the position of the split core can be adjusted according to usage needs.

[0104] In the above technical means, the stator core further includes a teeth portion and a yoke portion, and the stator core has at least a first state and a second state, and in the first state, the multiple split cores are rolled up to form a first annular shape, and the teeth portion is located inside the yoke portion, and in the second state, the multiple split cores are expanded in an approximately linear manner.

[0105] In this technical means, the stator core has a first state, which is a normal state after the stator core has been wound with windings, and in the first state, the multiple split cores are rounded into a first annular shape, and the teeth are located inside the yoke. In this state, the windings are wound around stator slots made up of adjacent teeth, and the windings are close to the inside of the stator core, and two adjacent stator cores are rotatably connected by overlapping portions installed on the outer yoke portions and are surrounded together to form a circular stator core.

[0106] The stator core further has a second state in which two adjacent split cores are rotatably connected, so that when two adjacent split cores in the stator core move relative to each other, the split cores can unfold in a substantially linear fashion. After unfolding, the teeth of each split core are distributed in a substantially linear fashion, and because the stator core is in the unfolded state, the space in the stator slot between the two teeth is increased compared to the first state, making it easier for the operator to wind the coils.

[0107] By placing the stator core in the second state, the teeth can be distributed in a generally linear fashion and the space in the stator slots can be increased, making it easier for the operator to wind the windings. After the winding operation is completed, the stator core is returned to the first state, and each split core is enclosed together in the circular stator core, making the stator core structure more stable and reliable.

[0108] Furthermore, in the second state, the two split cores at both ends are connected after being rolled, and specifically, the two split cores can be welded after being rolled.

[0109] As will be appreciated, in the second state, the stator core is generally linear, which includes the stator core being linear or the stator core having a constant arc.

[0112] As will be understood, when the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the circumferential direction of the stator core, the overlapping portions located on the first sides of the plurality of first punched piece layers are alternately arranged with the overlapping portions located on the second sides of the plurality of second punched piece layers. Furthermore, the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are respectively located on both sides of the split core and are alternately arranged.

[0114] By alternately arranging the first and second punched layers, with overlapping sections on different sides of the first and second punched layers, and by having the first and second punched layers surround the overlapping gaps on different sides, two adjacent split cores can be connected through the overlapping sections and overlapping gaps. Specifically, the overlapping section of one split core is inserted into the overlapping gap of the other split core. This connection method is stable and reliable, allowing operators to quickly install and remove stator cores, improving work efficiency. Furthermore, by using the same structure for multiple split cores, interconnection can be achieved, reducing the number of split core types, improving split core versatility, and reducing product costs.

[0116] In this technical solution, the multiple punched pieces include a first punched piece layer and a second punched piece layer, and the multiple first punched piece layers and the multiple second punched piece layers are distributed alternately along the axial direction of the stator core. The first punched piece layer has an overlapping portion on a first side, and the overlapping portion on the first punched piece layer protrudes from the second punched piece layer. The multiple first punched piece layers and the multiple second punched piece layers are arranged alternately, and two adjacent first punched piece layers both protrude from the second punched piece layer located between the two adjacent first punched piece layers, thereby enclosing an overlapping gap between the two adjacent first punched piece layers.

[0117] As will be understood, when the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the circumferential direction of the stator core, the overlapping portions located on the first sides of the plurality of first punched piece layers are alternately arranged with the overlapping portions located on the second sides of the plurality of second punched piece layers. Furthermore, the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are respectively located on both sides of the split core and are alternately arranged.

[0118] An overlapping portion and an overlapping gap are provided on the adjacent sides of two adjacent split cores, and the overlapping portions located on the first side of the multiple first punched piece layers and the overlapping portions located on the second side of the multiple second punched piece layers are alternately arranged, and the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are alternately arranged, and the overlapping portion of one split core is inserted into the overlapping gap of the other split core, thereby realizing the connection between the two adjacent split cores.

[0120] According to a third aspect of the present invention, there is further provided a motor including the stator according to the second aspect, and a rotor that rotates in cooperation with the stator.

[0121] The motor provided in the third aspect of the present application includes the stator provided in the first aspect, and therefore has all the beneficial effects of the stator.

[0122] Furthermore, the motor further includes a rotor, which is disposed inside the stator and rotates in cooperation with the stator, and is capable of outputting torque.

[0123] According to a fourth aspect of the present invention, there is further provided a compressor including the motor according to the third aspect.

[0124] The compressor provided in the fourth aspect of the present application includes the motor provided in the third aspect, and therefore has all the beneficial effects of the motor.

[0125] According to a fifth aspect of the present application, there is further provided a vehicle including the compressor according to the fourth aspect.

[0126] The vehicle provided in the fifth aspect of the present application includes the compressor provided in the fourth aspect, and thus has all the beneficial effects of the compressor.

[0127] A sixth aspect of the present application provides an insulating framework, including a first support, a second support arranged opposite the first support and having a terminal accommodating portion on a side of the second support away from the first support, the terminal accommodating portion being an accommodating groove used to accommodate a crimp terminal, the accommodating groove having notches in opposing side walls of the accommodating groove along a first direction, and an adhesive overflow groove located on at least one side of the accommodating groove along the first direction and communicating with the notches, and a third support arranged between the first support and the second support and connected to the first support and the second support.

[0128] The insulating framework provided herein includes a first support, a second support, and a third support, where the second support and the first support are distributed so as to face each other, and the third support is disposed between the first support and the second support, with one end of the third support connected to the first support and the other end of the third support connected to the second support, thereby connecting the first, second, and third supports together. The insulating framework further includes a terminal accommodating portion, where the terminal accommodating portion is disposed on the second support, and a crimp terminal is disposed in the terminal accommodating portion, and coils of the same phase are connected in series within the terminal accommodating portion by the crimp terminal. The terminal accommodating portion is disposed on the side of the second support away from the first support, thereby avoiding the occupation of coil winding space. At the same time, the terminal accommodating portion and the wire slots are distributed along a first direction, facilitating coil winding and series connection of coils of the same phase. In addition, by providing terminal accommodating grooves in the insulating framework and realizing electrical connection of each coil using crimp terminals, it is possible to avoid superimposing other structures that realize common-phase electrical connection above the insulating framework, further reducing the overall dimensions of the stator.

[0129] Here, the first direction is the circumferential direction of the stator core.

[0130] Furthermore, the terminal accommodating portion includes an accommodating groove and an adhesive overflow groove, and the accommodating groove is used to accommodate the crimp terminal of the stator, wherein a notch is provided in the accommodating groove, and the winding start and end portions of the in-phase coil extend from the notch on one side of the accommodating groove into the accommodating groove, which plays a role in positioning the coil and ensures the stability of the coil, while at the same time realizing the electrical connection of the in-phase coil by the crimp terminal.

[0131] In addition, the adhesive overflow groove is installed on at least one side of the accommodating groove and communicates with the notch. In this way, after the same-phase coils are electrically connected by the connecting terminals, the coils are sealed with sealant in the accommodating groove and notch, improving the safety performance of the coil. Furthermore, by installing the adhesive overflow groove, excess sealant is caught in the adhesive overflow groove during the process of sealing the crimp terminal with sealant, so that the sealant does not overflow outside the terminal accommodating portion and achieves good sealing of the coil.

[0132] In a specific application, the receiving groove has two notches, and the two notches are respectively disposed on two side walls of the receiving groove in the first direction. Similarly, the number of adhesive overflow grooves is two, and the two adhesive overflow grooves are disposed corresponding to the two notches, so that when sealing the two notches, the adhesive overflow grooves can be prevented from overflowing from either of the two notches.

[0133] As can be seen, when sealing the crimp terminal and the cut end of the conductor, if a low-viscosity sealant is used, the sealant will tend to flow down the side walls of the receiving groove, making it difficult to achieve a complete seal for the crimp terminal and the cut end of the conductor. If a high-viscosity sealant is used, the sealant will not flow well and the notch of the receiving groove will be narrow, making it very difficult to completely cover the crimp terminal and the cut end of the conductor. Therefore, the present invention provides an adhesive overflow groove to prevent the sealant from overflowing and achieve a complete seal for the crimp terminal and the cut end of the coil conductor. Furthermore, when sealing the end of the coil, good sealing of the end of the coil can be achieved.

[0134] According to the above insulating framework provided in the present application, it can have the following additional technical features:

[0135] In the above technical means, the terminal accommodating portion further includes an adhesive overflow pad provided on both sides of the accommodating groove along the first direction, and a boss provided on the adhesive overflow pad, at least the boss surrounding the adhesive overflow groove together with the adhesive overflow pad.

[0136] In this technical solution, the terminal accommodating portion further includes an adhesive overflow pad and a boss, and the adhesive overflow pads are installed on both sides of the accommodating groove, i.e., the terminal accommodating portion has adhesive overflow pads protruding on both sides in the first direction of the accommodating groove. When the boss is installed on the adhesive overflow pad, at least the adhesive overflow pad and the boss surround the adhesive overflow groove, and the adhesive overflow groove surrounds at least a portion of the notch. Furthermore, when sealant is poured into the accommodating groove and the notch to seal, excess sealant can flow into the adhesive overflow groove, preventing the sealant from overflowing from the terminal accommodating portion.

[0137] As will be appreciated, the crimp terminals penetrate the coils, thereby connecting the in-phase coils.

[0138] In a specific application, the crimp terminal is a break-through terminal, so that when the crimp terminal is pressed against the coil in the receiving groove, it can break through the insulating coating on the coil surface, thereby realizing electrical connection of the coils in the same phase and realizing quick connection.

[0139] In any of the above technical means, the boss further includes a first boss provided along the first direction on a first side of the accommodating groove and located on the side of the notch away from the first support, and a second boss provided along the first direction on a second side of the accommodating groove, surrounding the adhesive overflow groove together with the second support, the accommodating groove and the adhesive overflow base, with a notch provided between the accommodating groove and the second boss.

[0140] In this technical solution, the bosses include a first boss and a second boss, the first boss and the second boss are respectively installed on adhesive overflow pedestals on both sides of the receiving groove, the first boss is installed on the side of the receiving groove away from the terminal receiving portion and on the side of the notch away from the first support, so that when sealant is injected into the receiving groove and the notch, excess sealant is caught by the first boss and prevents the sealant from overflowing. The second boss is installed on the side of the receiving groove closer to the terminal receiving portion and surrounds the adhesive overflow groove together with the surface of the second support and the outer wall surface of the receiving groove, so that the area between the end of the second boss and the wall surface of the receiving groove is not completely closed but has a notch, thereby facilitating cutting and sealing of the end of the coil winding.

[0141] In a specific application, a wire slot is provided at the bottom of the first boss, and the wire slot is positioned opposite the notch, so that the coil can be further fixed within the wire slot and the robustness of the coil can be improved.

[0142] Furthermore, the size of the notch is small, which further prevents the sealant from leaking out. Specifically, the width of the notch is 1 mm or more and 5 mm or less.

[0143] In any of the above technical means, the notch further includes a first passage and a second passage that communicate with each other, the first passage is located at the top of the second passage, and the side walls of the first passage are arranged to gradually widen on both sides of the first passage.

[0144] In this technical solution, the notch includes a first passage and a second passage that communicate with each other, i.e., the notch is divided into an upper half and a lower half, wherein the first passage is located in the upper half and the second passage is located in the lower half, the upper and lower halves are connected, and the side walls of the first passage are arranged to gradually widen, making it easy to pass the coil through the notch. At the same time, the upper half of the notch is arranged at an angle, making it easy to inject the sealant, and the sealant can flow along the angled wall surfaces toward the bottom of the slot in the notch, improving the sealing effect of the sealant on the cut cross section of the coil.

[0145] In a specific application, the notch is generally U-shaped, the sidewall of the first passage is beveled, and the sidewall of the first passage is generally flat.

[0146] In any of the above technical means, the insulating framework further includes a protrusion, which is provided on a side of the second support away from the first support, and the protrusion and the terminal accommodating groove are arranged sequentially along the first direction.

[0147] In this technical solution, the insulating framework further includes a protrusion, which is installed on the second support and located on a side of the second support away from the first support and the third support, and the protrusion and the terminal accommodating portion are installed sequentially along the first direction, and the installation of the protrusion can play a role in regulating the position of the coil and prevent the coil from slipping out, specifically, the installation of the protrusion can prevent the end of the coil from slipping out and improve the fixation of the coil.

[0148] In a specific application, the stator includes a stator core, an insulating framework, and an insulating cover plate, the insulating framework being installed at both ends of the stator core, and the insulating cover plate being installed at both ends of the insulating framework away from the stator core. The insulating cover plate serves an insulating role and improves the safety performance of the motor. Here, the protrusions engage with the insulating cover plate to connect the insulating framework and the insulating cover plate, improving the reliability of the connection between the insulating cover plate and the insulating framework.

[0149] As will be appreciated, both the insulating cover plate and the insulating framework are made of insulating material.

[0150] Specifically, a wire slot is provided in the second support, and the protrusion, the wire slot, and the terminal receiving portion are sequentially arranged along a first direction. The wire slot includes a bottom wall, and the bottom wall of the wire slot is inclined toward the bottom of the second support to form an inclined portion, where the inclined portion is located on the side closer to the first support. In this way, when a wire is wound around the insulating framework, the coil extends from the side of the wire slot away from the first support into the wire slot and then extends along the inclined portion to the bottom of the first support, which facilitates coil winding. Moreover, the wire slot can pre-fix the coil, making the coil winding more compact, improving coil fixation and increasing the space factor of the stator core.

[0151] In a specific application, the insulating framework is applied to a stator, which includes a stator core, a coil, and the insulating framework, where the insulating framework is installed at both axial ends of the stator core, and the coil is wound around the insulating framework and the stator core. The first support, the second support, and the third support together surround a winding receiving portion for receiving the coil, and the stator core is pulled through the wire slot, so that the coil is inclined downward along the inclined portion, and the coil is wound more tightly.

[0152] As can be understood, the wire slot includes an opening and a bottom wall facing the opening, a portion of the bottom wall of the wire slot is inclined toward the bottom of the second support to form a slope, and the slope is located on the side of the wire slot facing the first support, i.e., the slope is located inside the first support. That is, the upper half of the wire slot is approximately U-shaped, the opening is located at the top of the U, and the lower half of the wire slot is sloped, which makes the coil more compact when passing through and improves the fixation of the coil winding.

[0153] Specifically, when the insulating framework is applied to a stator, the first support is close to the inside of the stator core, the second support is close to the outside of the stator core, and the third support is connected to and located between the first support and the second support.

[0154] For the split cores, one coil is wound around each split core, and each coil includes a winding start portion and a winding end portion. After winding is completed, the winding end portion extends from the bottom of the protrusion into the wire slot, and the position of the coil is regulated by the wire slot.

[0155] As can be understood, along the first direction, the wire slot includes a first side and a second side, and the first side of the wire slot and the second side of the wire slot are oppositely disposed opposite sides of the wire slot, where the side of the wire slot closer to the terminal accommodating portion is the first side of the wire slot, and the side of the wire slot closer to the protrusion is the second side of the wire slot.

[0156] Additionally, the width of the wire slot is greater than the width of the notch.

[0157] In this technical solution, both the beginning and end of the coil are placed in the notch, making it easier for the coil to enter the slot, and because the width of the wire slot is larger than the width of the notch, the beginning and end of the coil are more tightly connected to the notch when entering the notch, improving the fixation of the notch to the coil.

[0158] In a specific application, the width of the wire slot is the width of the wire slot along the first direction, and the width of the notch is the width of the notch along the second direction. Specifically, the wire slot and the notch are both approximately U-shaped, and the width of the wire slot and the width of the notch are the distance between the left and right sidewalls of the U-shape.

[0159] By setting the width of the notch and the wire slot, the start and end of the coil can be accommodated simultaneously within the notch, while improving the compactness of the coil.

[0160] In any of the above technical means, at least a part of the top wall of the protrusion is further inclined toward the bottom of the second support.

[0161] In this technical solution, at least a portion of the top wall of the protrusion is inclined toward the bottom of the second support, thereby reducing the material used for the protrusion and reducing production costs, while avoiding interference with other structures when the insulating framework is used in combination with other structures.

[0162] In a specific application, the cross section of the protrusion is generally triangular.

[0163] In any of the above technical means, furthermore, the length by which the terminal accommodating portion protrudes from the second support body is greater than the length by which the protruding portion protrudes from the second support body.

[0164] In this technical solution, the terminal accommodating portion and the protruding portion both protrude from the second support away from the first support, and the protruding length of the protruding portion from the second support is shorter than the protruding length of the terminal accommodating portion from the second support. In this way, when the insulating framework is connected to the insulating cover plate, interference with the connection between the two is avoided, and the connection reliability between the two is ensured.

[0165] As can be seen, the second support, the third support and the first support are sequentially distributed along the second direction, and the length of the protrusion along the second direction is smaller than the length of the terminal accommodating portion.

[0166] As will be understood, the second direction is the radial direction of the stator core.

[0167] In any of the above technical means, furthermore, a surface of the protrusion close to the bottom of the second support is located on a side of the bottom wall of the wire slot away from the bottom of the second support.

[0168] In this technical solution, the surface of the protrusion close to the bottom of the second support is located on the side of the bottom wall of the wire slot that is away from the bottom of the second support. With this arrangement, the surface of the protrusion close to the bottom of the second support is higher than the bottom wall of the wire slot, i.e., the bottom wall of the wire slot is lower than the underside of the protrusion. Furthermore, the end of the coil is wound into the wire slot from the side of the protrusion that is away from the wire slot, which prevents the coil from bending in the wire slot and makes the coil routing more tightly.

[0169] Specifically, the difference in distance between the lower surface of the protrusion and the bottom wall of the wire slot is equal to or greater than the diameter of the conductor wire in the coil. As will be understood, a single conductor wire is wound around a split core and an insulating framework to form a coil.

[0170] In any of the above technical means, the insulating framework may further include a stepped portion provided on the second support and located on a side of the protrusion away from the terminal accommodating portion.

[0171] In this technical solution, the insulating framework further includes a stepped portion, which is attached to the second support and used to support the coil, specifically, the stepped portion is used to support the end of the coil winding, thereby improving the tightness of the coil winding.

[0172] Specifically, the step portion is located on the side of the protrusion away from the wire slot, and thus the end of the coil is wound from the top surface of the step portion below the protrusion and further extends into the wire slot, which fixes the end of the coil.

[0173] In any of the above technical solutions, the third support may further include a plurality of auxiliary slots, each of which extends along a first direction and the plurality of auxiliary slots are distributed along a second direction, with the first support, the third support, and the second support being sequentially distributed along the second direction.

[0174] In this technical solution, auxiliary slots are provided on the third support, and the number of the auxiliary slots is plural, and the coil is fixed by the auxiliary slots to improve the tightness and stability of the coil winding, wherein each auxiliary slot extends along a first direction, and the plural auxiliary slots are distributed in an array along a second direction, and the coil is wound on the insulating framework by the auxiliary slots.

[0175] Specifically, the auxiliary slot is installed on the upper surface of the third support, and when the auxiliary slot naturally extends along the outer surface of the third support, it is cut directly and flat by the side surface of the third support.

[0176] Specifically, the second direction is the radial direction of the stator.

[0177] In any of the above technical means, furthermore, an edge of the inclined portion close to the bottom of the second support is substantially flush with the slot bottom of the auxiliary slot.

[0178] In this technical solution, the edge of the inclined portion near the bottom of the second support is substantially flush with the slot bottom of the auxiliary slot, which prevents bending of the coil and ensures tightness of the coil winding.

[0179] As will be understood, the edge of the ramp that is closest to the bottom of the second support is the lower edge of the ramp, and the lower edge of the ramp is generally flush with the slot bottom of the auxiliary slot, i.e., the lower edge of the ramp is flush with the slot bottom of the auxiliary slot, or the lower edge of the ramp is slightly higher than the slot bottom of the auxiliary slot.

[0180] In any of the above technical means, furthermore, a wall surface of the wire slot close to the terminal accommodating portion is substantially flush with a wall surface of the third support close to the wire slot.

[0181] In this technical solution, the wall surface of the wire slot near the terminal accommodating portion is approximately flush with the wall surface of the third support near the wire slot, and thus when the coil is wound from the wire slot to the third support, the coil can be wound more tightly, improving the space factor of the stator core.

[0182] As will be understood, the wall surface near the terminal accommodating portion of the wire slot is approximately flush with the wall surface near the wire slot of the third support, i.e., the wall surface near the accommodating portion of the wire slot is flush with the wall surface near the wire slot of the third support, or there is a minute pitch between the wall surface near the accommodating portion of the wire slot and the wall surface near the wire slot of the third support.

[0183] In any of the above technical means, a cutout is further provided on the side of the first support facing the second support, the cutout is located close to the bottom of the first support, and the cutout is located on both sides of the third support along the first direction.

[0184] In this technical solution, a notch is provided in the first support, and the notch is located inside the first support, allowing the coil winding to escape and ensuring the tightness of the coil winding.

[0185] Specifically, the notch is located on the side of the first support facing the second support and is installed close to the bottom of the first support; and further, along the first direction, the notch is installed on both sides of the third support, which not only further reduces the overall weight of the insulating framework and reduces production costs, but also prevents the third support from excessively pressing on the coil and affecting the winding of the coil.

[0186] In a specific application, the wall surface of the first support facing the second support is generally flat, and the wall surface of the first support facing away from the second support is arc-shaped. When the insulating framework is applied to a stator, the first support can be circular to accommodate the shape of the stator teeth, further facilitating rotor installation and movement. At the same time, the cutouts allow the shape of the first support to fit the end of the stator teeth facing the inside of the stator, increasing the space factor of the stator and simultaneously making the overall connection tighter.

[0187] Specifically, the notch is a flat, non-through structure.

[0188] In any of the above technical means, furthermore, the side of the notch closer to the top of the first support is flush with the top of the auxiliary slot.

[0189] In this technical solution, the side of the notch near the top of the first support is flush with one side of the top of the auxiliary slot, which further ensures the relief effect of the notch on the coil and increases the space factor of the stator.

[0190] In any of the above technical means, the insulating framework may further include a mark provided on at least one of the second support and the first support, the mark corresponding to the width of the notch and the width of the auxiliary slot of the third support.

[0191] In this technical solution, the insulating framework further includes marks set on at least one of the second support and the first support, which, as can be understood, correspond to different coil diameters, different auxiliary slot widths, and different notch widths when winding different stators. That is, the coil diameter corresponds one-to-one to the notch width and the auxiliary slot width, and therefore the coil diameter changes synchronously with the notch width and the auxiliary slot width. Therefore, the technical solution proposed by the present application sets marks on the insulating framework, which correspond one-to-one to the coil diameter, notch width, and auxiliary slot width. In this way, different insulating frameworks can be selected according to the marks based on different coil diameters. Specifically, different insulating frameworks correspond to different sized notch widths and auxiliary slot widths, so that insulating frameworks with various dimensional specifications can be adapted to coils of different sizes.

[0192] Specifically, the width of the notch and the yoke width of the auxiliary slot have various dimensions, which can be selected and used according to the actual situation.

[0193] Specifically, the mark may be a number, an alphabet, or a symbol having an equivalent function.

[0194] In a specific application, the mark is placed on the terminal receiving portion of the second support, and the mark is placed on the top of the terminal receiving portion so that the user can easily recognize it.

[0195] According to a seventh aspect of the present application, a stator is further provided, including a crimp terminal provided in the accommodating groove, a stator core including a plurality of split cores connected in series, each split core including a tooth portion, and the tooth portions of two adjacent split cores together surrounding the stator slot, an insulating framework provided in any one of the sixth aspect, in which there are a plurality of insulating frameworks, each of which is provided at both ends of one of the split cores, and a third support is installed opposite the tooth portion, and a winding wound around the tooth portion and the insulating framework.

[0196] The stator provided in the seventh aspect of the present application includes the insulating framework proposed by any of the above technical means, and therefore has all the beneficial effects of the insulating framework.

[0197] The stator further includes a stator core, which includes a plurality of sequentially connected split cores, each split core including a tooth portion, and a stator slot for accommodating windings, which is enclosed between the teeth of two adjacent split cores, and an insulating framework is installed at both ends of each split core, allowing the windings to be wound around the tooth portion and the insulating framework, ensuring insulation performance. At the same time, this winding method allows the windings to be electrically connected to the insulating framework alone, eliminating the need for other structures to achieve electrical connection, further reducing the axial height of the stator and making the end of the stator more compact.

[0198] Furthermore, the winding includes multiple coils, one coil wound around one split core and insulating frameworks at both ends of the split core, the coil includes a winding start portion and a winding end portion, and the wire slot is used to accommodate the winding start portion and the winding end portion.

[0199] In this technical solution, the winding includes multiple coils, and one split core and an insulating framework at both ends thereof constitute one core component, in which one coil is wound on each core component, and after the winding of each coil is completed, the multiple core components are rolled up to form a stator, which further improves the space factor and prevents scratches on the insulating layer on the coil surface.

[0200] Here, the coil includes a start portion and an end portion, and wire slots are used to accommodate the start portion and the end portion to ensure tightness of the coil winding.

[0201] Specifically, the winding start portion is engaged in the wire slot at one end of the stator core in the axial direction and extends to the other end of the stator core, and winding begins on the side of the insulating framework far from the wire slot, and the winding end portion is located on the side of the insulating framework close to the wire slot, and then the winding end portion is wound around the step portion, extends over the upper surface of the step portion to below the protrusion, and then extends into the wire slot and is pre-fixed in the wire slot. After all the coils have been wound, the multiple split cores are rolled to form the stator. Compared to the prior art, the technical solution proposed in this application not only improves the space factor of the stator, but also prevents damage to the insulation layer of the coil itself.

[0202] In any of the above technical means, the stator further includes insulating cover plates, which are provided on both sides of the insulating framework, and have relief grooves, which are installed corresponding to marks on the insulating framework and are used to relieve the marks.

[0203] In this technical solution, the stator further includes an insulating cover plate, and the insulating cover plate is provided with a relief groove for accommodating a mark on the insulating framework.

[0204] The stator further includes an insulating cover plate located on a side of the insulating framework away from the stator core and engaging the projections of the insulating framework.

[0205] In this technical solution, the insulating framework further includes an insulating cover plate installed on the side of the insulating framework away from the stator core, and the installation of the insulating framework can realize rounded insulation protection for both ends of the coil and improve the safety performance of the stator. Here, the insulating cover plate is connected to the protrusions of the insulating framework to realize the fixing of the insulating cover plate, making the overall structure of the stator more compact and achieving effective engagement between the two.

[0206] Additionally, the insulating cover plate engages the projections of the insulating framework.

[0207] In a specific application, a snap is installed on the insulating cover plate, and the snap engages with the protrusion. As can be understood, the length of the protrusion is shorter than the length of the terminal receiving part, so that the engagement between the snap and the protrusion is guaranteed.

[0208] Furthermore, any of the split cores includes a plurality of stamped pieces that are stacked and distributed along the axial direction of the stator core.

[0209] In this technical solution, each split core is configured to include a plurality of punched pieces that are stacked and distributed along the axial direction of the stator core, and overlapping portions are formed on the peripheral edges of the punched pieces. When the plurality of punched pieces are stacked and distributed along the axial direction of the core, overlapping gaps are limited between adjacent punched pieces and are formed in the stator slots, making it easy for the windings to be wound around the teeth of the stator core and located within the stator slots.

[0210] Specifically, the punched piece is a silicon steel plate.

[0211] Furthermore, two adjacent split cores are rotatably connected by an overlapping portion.

[0212] In this technical solution, two adjacent split cores are rotatably connected by an overlapping portion, that is, the two connected split cores are rotatable relative to each other.

[0213] By connecting two adjacent split cores rotatably through an overlapping portion, one split core can be rotated around the other split core, with the connection point of the overlapping portion as the center of the circle. This connection method is simple and reliable, and allows the operator to easily adjust the outer shape and structure of the stator core, and the position of the split core can be adjusted according to usage needs.

[0214] In the above technical means, the stator core further includes a teeth portion and a yoke portion, and the stator core has at least a first state and a second state, and in the first state, the multiple split cores are rolled up to form a first annular shape, and the teeth portion is located inside the yoke portion, and in the second state, the multiple split cores are expanded in an approximately linear manner.

[0215] In this technical means, the stator core has a first state, which is a normal state after the stator core has been wound with windings, and in the first state, the multiple split cores are rounded into a first annular shape, and the teeth are located inside the yoke. In this state, the windings are wound around stator slots made up of adjacent teeth, and the windings are close to the inside of the stator core, and two adjacent stator cores are rotatably connected by overlapping portions installed on the outer yoke portions and are surrounded together to form a circular stator core.

[0216] The stator core further has a second state in which two adjacent split cores are rotatably connected, so that when two adjacent split cores in the stator core move relative to each other, the split cores can unfold in a substantially linear fashion. After unfolding, the teeth of each split core are distributed in a substantially linear fashion, and because the stator core is in the unfolded state, the space in the stator slot between the two teeth is increased compared to the first state, making it easier for the operator to wind the coils.

[0217] By placing the stator core in the second state, the teeth can be distributed in a generally linear fashion and the space in the stator slots can be increased, making it easier for the operator to wind the windings. After the winding operation is completed, the stator core is returned to the first state, and each split core is enclosed together in the circular stator core, making the stator core structure more stable and reliable.

[0218] Furthermore, in the second state, the two split cores at both ends are connected after being rolled, and specifically, the two split cores can be welded after being rolled.

[0219] As will be appreciated, in the second state, the stator core is generally linear, which includes the stator core being linear or the stator core having a constant arc.

[0220] In the above technical means, the plurality of punched pieces further include first punched piece layers and second punched piece layers arranged alternately, an overlapping portion is arranged on a first side of the first punched piece layer, the overlapping portion on the first punched piece layer protrudes from the second punched piece layer, two adjacent first punched piece layers together enclose an overlapping gap, an overlapping portion is arranged on a second side of the second punched piece layer, the overlapping portion on the second punched piece layer protrudes from the first punched piece layer, two adjacent second punched piece layers together enclose an overlapping gap, and the overlapping portion of one of the two adjacent split cores is inserted into the overlapping gap of the other split core.

[0221] In this technical solution, the multiple punched pieces include a first punched piece layer and a second punched piece layer, and the multiple first punched piece layers and the multiple second punched piece layers are distributed alternately along the axial direction of the stator core. The first punched piece layer has an overlapping portion on a first side, and the overlapping portion on the first punched piece layer protrudes from the second punched piece layer. The multiple first punched piece layers and the multiple second punched piece layers are arranged alternately, and two adjacent first punched piece layers both protrude from the second punched piece layer located between the two adjacent first punched piece layers, thereby enclosing an overlapping gap between the two adjacent first punched piece layers. The second punched piece layer has an overlapping portion on a second side, that is, the overlapping portion of the second punched piece layer is located on a side different from that of the first punched piece layer. The overlapping portion on the second punched piece layer protrudes from the first punched piece layer, and a plurality of first punched piece layers and a plurality of second punched piece layers are alternately arranged, with each of two adjacent second punched piece layers protruding from the first punched piece layer located midway between the two adjacent second punched piece layers, so that an overlapping gap can also be enclosed between the two adjacent second punched piece layers.

[0222] As will be understood, when the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the circumferential direction of the stator core, the overlapping portions located on the first sides of the plurality of first punched piece layers are alternately arranged with the overlapping portions located on the second sides of the plurality of second punched piece layers. Furthermore, the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are respectively located on both sides of the split core and are alternately arranged.

[0223] An overlapping portion and an overlapping gap are provided on the adjacent sides of two adjacent split cores, and the overlapping portions located on the first side of the multiple first punched piece layers and the overlapping portions located on the second side of the multiple second punched piece layers are alternately arranged, and the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are alternately arranged, and the overlapping portion of one split core is inserted into the overlapping gap of the other split core, thereby realizing the connection between the two adjacent split cores.

[0224] By alternately arranging the first and second punched layers, with overlapping sections on different sides of the first and second punched layers, and by having the first and second punched layers surround the overlapping gaps on different sides, two adjacent split cores can be connected through the overlapping sections and overlapping gaps. Specifically, the overlapping section of one split core is inserted into the overlapping gap of the other split core. This connection method is stable and reliable, allowing operators to quickly install and remove stator cores, improving work efficiency. Furthermore, by using the same structure for multiple split cores, interconnection can be achieved, reducing the number of split core types, improving split core versatility, and reducing product costs.

[0225] In the above technical means, the plurality of punched pieces further include first punched piece layers and second punched piece layers arranged alternately, an overlapping portion is arranged on a first side of the first punched piece layer, the overlapping portion on the first punched piece layer protrudes from the second punched piece layer, two adjacent first punched piece layers together enclose an overlapping gap, an overlapping portion is arranged on a second side of the second punched piece layer, the overlapping portion on the second punched piece layer protrudes from the first punched piece layer, two adjacent second punched piece layers together enclose an overlapping gap, and the overlapping portion of one of the two adjacent split cores is inserted into the overlapping gap of the other split core.

[0226] In this technical solution, the multiple punched pieces include a first punched piece layer and a second punched piece layer, and the multiple first punched piece layers and the multiple second punched piece layers are distributed alternately along the axial direction of the stator core. The first punched piece layer has an overlapping portion on a first side, and the overlapping portion on the first punched piece layer protrudes from the second punched piece layer. The multiple first punched piece layers and the multiple second punched piece layers are arranged alternately, and two adjacent first punched piece layers both protrude from the second punched piece layer located between the two adjacent first punched piece layers, thereby enclosing an overlapping gap between the two adjacent first punched piece layers. The second punched piece layer has an overlapping portion on a second side, that is, the overlapping portion of the second punched piece layer is located on a side different from that of the first punched piece layer. The overlapping portion on the second punched piece layer protrudes from the first punched piece layer, and a plurality of first punched piece layers and a plurality of second punched piece layers are alternately arranged, with each of two adjacent second punched piece layers protruding from the first punched piece layer located midway between the two adjacent second punched piece layers, so that an overlapping gap can also be enclosed between the two adjacent second punched piece layers.

[0227] As will be understood, when the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the circumferential direction of the stator core, the overlapping portions located on the first sides of the plurality of first punched piece layers are alternately arranged with the overlapping portions located on the second sides of the plurality of second punched piece layers. Furthermore, the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are respectively located on both sides of the split core and are alternately arranged.

[0228] An overlapping portion and an overlapping gap are provided on the adjacent sides of two adjacent split cores, and the overlapping portions located on the first side of the multiple first punched piece layers and the overlapping portions located on the second side of the multiple second punched piece layers are alternately arranged, and the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are alternately arranged, and the overlapping portion of one split core is inserted into the overlapping gap of the other split core, thereby realizing the connection between the two adjacent split cores.

[0242] In order to make the above-mentioned objects, features and advantages of the present application more clearly understood, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. It should be noted that, unless there is a contradiction, the examples and features in the examples of the present application can be combined with each other.

[0243] Although numerous details are set forth in the following description for a thorough understanding of the present application, the present application may be embodied in forms different from those described herein, and the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0244] Hereinafter, an insulating framework, a stator, a motor, a compressor, and a vehicle according to some embodiments of the present application will be described with reference to FIGS.

[0245] Example 1: 1 and 2, according to one embodiment of a first aspect of the present application, there is provided an insulating framework, which includes a first support 1, a second support 2, and a third support 3.

[0246] Specifically, the second support 2 is installed opposite the first support 1, a wire slot 20 is provided in the second support 2, the wire slot 20 penetrates the wall surface of the second support 2, a portion of the bottom wall of the wire slot 20 is inclined toward the bottom of the second support 2 to form an inclined portion 22, the inclined portion 22 is located on the side of the wire slot 20 facing the first support 1, and the third support 3 is installed between the first support 1 and the second support 2 and is connected to the first support 1 and the second support 2.

[0247] The insulating framework provided in the present application includes a first support 1, a second support 2, and a third support 3, the second support 2 and the first support 1 being distributed so as to be disposed opposite each other, the third support 3 being disposed between the first support 1 and the second support 2, and one end of the third support 3 being connected to the first support 1 and the other end of the third support 3 being connected to the second support 2, thereby the first support 1, the second support 2, and the third support 3 being connected together. Here, a wire slot 20 is installed in the second support 2, and the wire slot 20 includes a bottom wall. The bottom wall of the wire slot 20 is inclined toward the bottom of the second support 2, forming an inclined portion 22, where the inclined portion 22 is located on the side closer to the first support 1. In this way, when winding a wire through the insulating framework, the coil extends from the side of the wire slot 20 away from the first support 1 into the wire slot 20, and then further extends along the inclined portion 22 to the bottom of the first support 1, which makes the coil winding easier. Moreover, the wire slot 20 can pre-fix the coil, making the coil winding more compact, improving the coil fixation and the space factor of the stator core 4.

[0248] In a specific application, the insulating framework is applied to a stator, which includes a stator core 4, a coil, and the insulating framework, where the insulating framework is installed on both axial ends of the stator core 4, and the coil is wound around the insulating framework and the stator core 4. The first support 1, the second support 2, and the third support 3 together surround a winding receiving portion for receiving the coil, and the stator core 4 is pulled through the wire slot 20, so that the coil is inclined downward along the inclined portion 22 and the coil is wound more tightly.

[0249] Specifically, the first support 1, the second support 2 and the third support 3 are integrally molded.

[0250] As can be seen, the wire slot 20 includes an opening and a bottom wall disposed opposite the opening, and a portion of the bottom wall of the wire slot 20 is disposed at an angle toward the bottom of the second support 2 to form a sloped portion 22, and the sloped portion 22 is disposed on the side of the wire slot 20 facing the first support 1, i.e., the sloped portion 22 is disposed inside the first support 1. In other words, the upper half of the wire slot 20 is approximately U-shaped, the opening is located at the top of the U-shape, and the lower half of the wire slot 20 is sloped, which makes the coil more compact when passing it through and improves the fixation of the coil winding.

[0251] Specifically, when the insulating framework is applied to a stator, the first support 1 is close to the inside of the stator core 4, the second support 2 is close to the outside of the stator core 4, and the third support 3 is connected to and located between the first support 1 and the second support 2.

[0252] Example 2: As shown in Figures 3 and 4, according to one embodiment of the present application, in addition to the above embodiment, the insulating framework further includes a terminal accommodating portion 24 provided on the side of the second support 2 away from the first support 1, used to accommodate a crimp terminal, and located on the first side of the wire slot 20 along the first direction.

[0253] In this embodiment, the insulating framework further includes a terminal accommodating portion 24, which is disposed on the second support 2. A crimp terminal is disposed in the terminal accommodating portion 24, and coils of the same phase are connected in series by the crimp terminal in the terminal accommodating portion 24. Here, the terminal accommodating portion 24 is disposed on the side of the second support 2 away from the first support 1, which further reduces the occupation of the coil winding space. At the same time, the terminal accommodating portion 24 and the wire slots 20 are distributed along the first direction, which facilitates coil winding and the series connection of coils of the same phase. In addition, the terminal accommodating grooves 240 disposed in the insulating framework avoid the need to overlap other structures realizing the same-phase electrical connection above the insulating framework, further reducing the overall size of the stator.

[0254] Here, the first direction is the circumferential direction of the stator core 4.

[0255] Example 3: As shown in Figures 1 and 3, according to one embodiment of the present application, in addition to the above embodiments, the terminal accommodating portion 24 further includes an accommodating groove 240, which is used to accommodate a crimp terminal, and which has a notch 2400 formed in the accommodating groove 240, the notch 2400 being located on a side wall of the accommodating groove 240 along a first direction, and adhesive overflow grooves 242 located on both sides of the accommodating groove 240 along the first direction and communicating with the notch 2400.

[0256] In this embodiment, the terminal accommodating portion 24 includes an accommodating groove 240 and an adhesive overflow groove 242. The accommodating groove 240 is used to accommodate the crimp terminal of the stator. A notch 2400 is formed in the accommodating groove 240. The beginning and end of the winding of the in-phase coil extend from the notch 2400 on one side of the accommodating groove 240 into the accommodating groove 240, which serves to position the coil and ensure its stability, while also realizing the electrical connection of the in-phase coil via the crimp terminal.

[0257] In addition, adhesive overflow grooves 242 are installed on both sides of the accommodating groove 240 and communicate with the notch 2400. In this way, after the same-phase coils are electrically connected by the connecting terminals, the coils are sealed with sealant in the accommodating groove 240 and the notch 2400, improving the safety performance of the coils. Furthermore, by installing the adhesive overflow grooves 242, excess sealant is received in the adhesive overflow groove 242 during the process of sealing the crimp terminal with sealant, preventing the sealant from overflowing outside the terminal accommodating portion 24, thereby achieving good sealing of the coils.

[0258] In a specific application, two notches 2400 are provided in the receiving groove 240, and the two notches 2400 are respectively provided on two side walls in the first direction of the receiving groove 240. Similarly, the number of adhesive overflow grooves 242 is two, and the two adhesive overflow grooves 242 are respectively provided corresponding to the two notches 2400, so that when sealing is performed at the two notches 2400, the adhesive overflow grooves 242 can prevent the sealant from overflowing from either of the two notches 2400.

[0259] As can be seen, when a low-viscosity sealant is used to seal the crimp terminal and the cut end of the conductor, the sealant tends to flow down the side walls of the receiving groove 240, making it difficult to completely seal the crimp terminal and the cut end of the conductor. When a high-viscosity sealant is used, the sealant does not flow well and the notch 2400 of the receiving groove 240 is narrow, making it very difficult to completely cover the crimp terminal and the cut end of the conductor. Therefore, the present application provides an adhesive overflow groove 242 to prevent the sealant from overflowing, thereby completely sealing the crimp terminal and the cut end of the coil conductor.

[0260] Example 4: As shown in Figures 2 and 3, according to one embodiment of the present application, in addition to the above embodiments, the terminal accommodating portion 24 further includes an adhesive overflow pad 244 provided on both sides of the accommodating groove 240 along the first direction, and a boss 246 provided on the adhesive overflow pad 244, and at least the boss 246 surrounds the adhesive overflow groove 242 together with the adhesive overflow pad 244.

[0261] In this embodiment, the terminal accommodating portion 24 further includes an adhesive overflow pad 244 and a boss 246, and the adhesive overflow pads 244 are installed on both sides of the accommodating groove 240, i.e., the terminal accommodating portion 24 has adhesive overflow pads 244 protruding on both sides of the accommodating groove 240 in the first direction. The boss 246 is installed on the adhesive overflow pad 244, so that at least the adhesive overflow pad 244 and the boss 246 surround the adhesive overflow groove 242, and the adhesive overflow groove 242 surrounds at least a portion of the notch 2400. Furthermore, when sealant is poured into the accommodating groove 240 and the notch 2400 to seal them, excess sealant can flow into the adhesive overflow groove 242, preventing the sealant from overflowing from the terminal accommodating portion 24.

[0262] As will be appreciated, the crimp terminals penetrate the coils, thereby connecting the in-phase coils.

[0263] In a specific application, the crimp terminal is a break-through terminal, so that when the crimp terminal is pressed against the coil in the receiving groove 240, it can break through the insulating coating on the surface of the coil, thereby realizing electrical connection of the coils in the same phase and realizing quick connection.

[0264] Furthermore, as shown in FIG. 2, the boss 246 includes a first boss 2460 provided on the side of the accommodating groove 240 away from the wire slot 20 and positioned on the side of the notch 2400 away from the first support 1, and a second boss 2462 provided on the side of the accommodating groove 240 closer to the wire slot 20, surrounding the adhesive overflow groove 242 together with the second support 2 and the accommodating groove 240, and having a notch between it and the accommodating groove 240.

[0265] In this embodiment, the boss 246 includes a first boss 2460 and a second boss 2462, and the first boss 2460 and the second boss 2462 are respectively installed on the adhesive overflow pads 244 on both sides of the accommodating groove 240, where the first boss 2460 is installed on the side of the accommodating groove 240 away from the wire slot 20 and is located on the side of the notch 2400 away from the first support 1, so that when sealant is injected into the accommodating groove 240 and the notch 2400, excess sealant is received by the first boss 2460, preventing the sealant from overflowing.

[0266] The second boss 2462 is located on the side of the accommodating groove 240 closer to the wire slot 20, and the second boss 2462 surrounds the adhesive overflow groove 242 together with the surface of the second support 2 and the outer wall surface of the accommodating groove 240, where the area between the end of the second boss 2462 and the wall surface of the accommodating groove 240 is not completely closed but has a notch, thereby facilitating cutting and sealing of the end of the coil winding.

[0267] In a specific application, a routing slot 20 is provided at the bottom of the first boss 2460, and the routing slot 20 is positioned opposite the notch 2400, so that the coil can be further fixed within the routing slot 20 and the robustness of the coil can be improved.

[0268] Furthermore, the size of the notch is small, which further prevents the sealant from leaking out. Specifically, the width of the notch is 1 mm or more and 5 mm or less.

[0269] Example 5: As shown in FIG. 5, according to one embodiment of the present application, in addition to the above embodiments, the notch 2400 further includes a first passage 2402 and a second passage 2404 that communicate with each other, the first passage 2402 is located at the top of the second passage 2404, and the side walls of the first passage 2402 are arranged to gradually widen on both sides of the first passage 2402.

[0270] In this embodiment, the notch 2400 includes a first passage 2402 and a second passage 2404 that are connected to each other, i.e., the notch 2400 is divided into an upper half and a lower half, where the first passage 2402 is located in the upper half and the second passage 2404 is located in the lower half, the upper and lower halves are connected, and the side walls of the first passage 2402 are gradually widened, making it easier to pass the coil through the notch 2400. At the same time, the upper half of the notch 2400 is inclined, making it easier to inject the sealant, and the sealant can flow along the inclined wall surface toward the bottom of the slot in the notch 2400, improving the sealing effect of the sealant on the cut cross section of the coil.

[0271] In a specific application, the notch 2400 is generally U-shaped, the sidewalls of the first passageway 2402 are beveled, and the sidewalls of the manway are generally flat.

[0272] Example 6: According to one embodiment of the present application, in addition to the above embodiments, the width of the wire slot 20 is greater than the width of the notch 2400 .

[0273] In this embodiment, both the beginning and end of the coil are positioned within the notch 2400, making it easier for the coil to enter the slot, and because the width of the wire slot 20 is greater than the width of the notch 2400, the beginning and end of the coil are more tightly connected to the notch 2400 when entering the notch 2400, improving the fixation of the notch 2400 to the coil.

[0274] In a specific application, the width of the wire slot 20 is the width of the wire slot 20 along the first direction, and the width of the notch 2400 is the width of the notch 2400 along the second direction. Specifically, the wire slot 20 and the notch 2400 are both approximately U-shaped, and the width of the wire slot 20 and the width of the notch 2400 are the distance between the left and right sidewalls of the U-shape.

[0275] By setting the width of the notch 2400 and the wire slot 20 as described above, the start and end of the coil can be accommodated simultaneously within the notch 2400, while improving the compactness of the coil.

[0276] Example 6: As shown in Figures 6, 7 and 9, according to one embodiment of the present application, in addition to the above embodiments, the insulating framework further includes a protrusion 26 provided on the side of the second support 2 away from the first support 1 and located on the second side of the wire slot 20 along the first direction.

[0277] In this embodiment, the insulating framework further includes a protrusion 26, which is installed on the second support 2 and located on the side of the second support 2 away from the first support 1 and the third support 3. The protrusion 26, the wire slot 20 and the terminal accommodating portion 24 are sequentially installed along the first direction. The installation of the protrusion 26 can serve to restrict the position of the coil and prevent the coil from slipping out. Specifically, the installation of the protrusion 26 can prevent the end of the coil from slipping out, improving the fixation of the coil.

[0278] Specifically, for each split core, one coil is wound around each split core, and each coil includes a winding start portion and a winding end portion. After winding is completed, the winding end portion extends from the bottom of the protrusion portion 26 into the wire slot 20, and the position of the coil is regulated by the wire slot 20.

[0279] As can be understood, along the first direction, the wire slot 20 includes a first side and a second side, and the first side of the wire slot 20 and the second side of the wire slot 20 are oppositely disposed opposite sides of the wire slot 20, where the side of the wire slot 20 closer to the terminal accommodating portion 24 is the first side of the wire slot 20, and the side of the wire slot 20 closer to the protrusion 26 is the second side of the wire slot 20.

[0280] Example 7: As shown in FIGS. 6 and 7, according to one embodiment of the present application, in addition to the above embodiment, at least a portion of the top wall of the protrusion 26 is inclined toward the bottom of the second support 2.

[0281] In this embodiment, at least a portion of the top wall of the protrusion 26 is inclined toward the bottom of the second support 2, thereby reducing the material used for the protrusion 26 and reducing production costs, while avoiding interference with other structures when the insulating framework is used in combination with other structures.

[0282] In a specific application, the cross section of the protrusion 26 is generally triangular.

[0283] In a specific application, the motor includes a stator core 4, an insulating framework, and an insulating cover plate 6. The insulating framework is installed on both ends of the stator core 4, and the insulating cover plate 6 is installed on both ends of the insulating framework that are distant from the stator core 4. The insulating cover plate 6 serves an insulating role and improves the safety performance of the motor. Here, the protrusions 26 engage with the insulating cover plate 6, connecting the insulating framework and the insulating cover plate 6 and improving the reliability of the connection between the insulating cover plate 6 and the insulating framework.

[0284] As will be appreciated, both the insulating cover plate 6 and the insulating framework are made of insulating material.

[0285] Furthermore, the surface of the protrusion 26 that is closer to the bottom of the second support 2 is located on the side of the bottom wall of the wire slot 20 that is farther from the bottom of the second support 2 .

[0286] In this embodiment, the surface of the protrusion 26 closest to the bottom of the second support 2 is located on the side of the bottom wall of the wire slot 20 that is farther from the bottom of the second support 2. With this arrangement, the surface of the protrusion 26 closest to the bottom of the second support 2 is higher than the bottom wall of the wire slot 20, i.e., the bottom wall of the wire slot 20 is lower than the lower surface of the protrusion 26. Furthermore, the end of the coil is wound into the wire slot 20 from the side of the protrusion 26 that is farther from the wire slot 20, which prevents the coil from bending in the wire slot 20 and makes the coil routing tighter.

[0287] Specifically, the difference in distance between the underside of the protrusion 26 and the bottom wall of the wire slot 20 is equal to or greater than the diameter of the conductor wire in the coil. As will be appreciated, a length of conductor wire is wound around a split core and an insulating framework to form a coil.

[0288] Furthermore, the length by which the terminal accommodating portion 24 protrudes from the second support body 2 is greater than the length by which the protruding portion 26 protrudes from the second support body 2 .

[0289] In this embodiment, both the terminal accommodating portion 24 and the protrusion protrude from the second support 2 away from the first support 1, and the protrusion length from the second support 2 is shorter than the protrusion length from the second support 2 of the terminal accommodating portion 24. In this way, when the insulating framework is connected to the insulating cover plate 6, interference with the connection between the two is avoided, and the connection reliability between the two is ensured.

[0290] As can be seen, the second support 2, the third support 3 and the first support 1 are distributed sequentially along the second direction, and the length of the protrusion along the second direction is smaller than the length of the terminal accommodating portion 24.

[0291] As will be understood, the second direction is the radial direction of the stator core 4.

[0292] Example 8: As shown in Figures 5 and 9, according to one embodiment of the present application, in addition to the above embodiment, the insulating framework further includes a step portion 28 provided on the second support 2 and located on the side of the protrusion portion 26 away from the wire slot 20.

[0293] In this embodiment, the insulating framework further includes a stepped portion 28, which is attached to the second support 2 and is used to support the coil, specifically, the stepped portion 28 is used to support the end of the coil, thereby improving the tightness of the coil winding.

[0294] Specifically, the step portion 28 is located on the side of the protrusion 26 away from the wire slot 20, and thus the end of the coil is wound from the upper surface of the step portion 28 below the protrusion 26 and further extends into the wire slot 20, which fixes the end of the coil.

[0295] Example 9: As shown in Figures 1 to 7, according to one embodiment of the present application, in addition to the above embodiments, a plurality of auxiliary slots 30 are provided in the third support 3, any one of the auxiliary slots 30 extends along a first direction, and the plurality of auxiliary slots 30 are distributed along a second direction, and the first support 1, the third support 3 and the second support 2 are distributed sequentially along the second direction.

[0296] In this embodiment, auxiliary slots 30 are provided on the third support 3, and there are a plurality of auxiliary slots 30. The coil is fixed by the auxiliary slots 30, thereby improving the tightness and stability of the coil winding. Here, each auxiliary slot 30 extends along a first direction, and the plurality of auxiliary slots 30 are distributed in an array along a second direction, and the coil is wound on the insulating framework through the auxiliary slots 30.

[0297] Specifically, the auxiliary slot 30 is installed on the upper surface of the third support 3, and when the auxiliary slot 30 naturally extends along the outer surface of the third support 3, it is cut directly and flat by the side of the third support 3.

[0298] Example 10: As shown in FIG. 4, according to one embodiment of the present application, in addition to the above embodiment, the edge of the inclined portion 22 close to the bottom of the second support 2 is substantially flush with the slot bottom of the auxiliary slot 30.

[0299] In this embodiment, the edge of the inclined portion 22 near the bottom of the second support 2 is approximately flush with the slot bottom of the auxiliary slot 30, preventing the coil from bending and ensuring tightness of the coil winding.

[0300] As will be understood, the edge of the inclined portion 22 closest to the bottom of the second support 2 is the lower edge of the inclined portion 22. The lower edge of the inclined portion 22 is approximately flush with the slot bottom of the auxiliary slot 30, that is, the lower edge of the inclined portion 22 is flush with the slot bottom of the auxiliary slot 30, or the lower edge of the inclined portion 22 is slightly higher than the slot bottom of the auxiliary slot 30.

[0301] Furthermore, the wall surface of the wire slot 20 close to the terminal accommodating portion 24 is substantially flush with the wall surface of the third support 3 close to the wire slot 20 .

[0302] In this embodiment, the wall surface of the wire slot 20 near the terminal accommodating portion 24 is approximately flush with the wall surface of the third support 3 near the wire slot 20. In this way, when the coil is wound from the wire slot 20 to the third support 3, the coil can be wound more tightly, improving the space factor of the stator core 4.

[0303] As can be seen, the wall surface near the terminal accommodating portion 24 of the wire slot 20 is approximately flush with the wall surface near the wire slot 20 of the third support 3, that is, the wall surface near the accommodating portion of the wire slot 20 is flush with the wall surface near the wire slot 20 of the third support 3, or there is a minute pitch between the wall surface near the accommodating portion of the wire slot 20 and the wall surface near the wire slot 20 of the third support 3.

[0304] Example 11: As shown in FIG. 7, according to one embodiment of the present application, in addition to the above embodiment, a notch 10 is further provided on the side of the first support 1 facing the second support 2, the notch 10 is located close to the bottom of the first support 1, and along the first direction, the notch 10 is located on both sides of the third support 3.

[0305] In this embodiment, a notch 10 is provided in the first support 1, and the notch 10 is located inside the first support 1, allowing the coil winding to escape and ensuring the tightness of the coil winding.

[0306] Specifically, the notch 10 is located on the side of the first support 1 facing the second support 2 and is installed close to the bottom of the first support 1; further, along the first direction, the notch 10 is installed on both sides of the third support 3, which not only further reduces the overall weight of the insulating framework and reduces production costs, but also prevents the third support 3 from excessively pressing on the coil and affecting the winding of the coil.

[0307] In a specific application, the wall surface of the first support 1 facing the second support 2 is generally flat, and the wall surface of the first support 1 facing away from the second support 2 is arc-shaped. When the insulating framework is applied to a stator, the first support 1 can surround a circle to accommodate the shape of the stator teeth, further facilitating rotor installation and movement. At the same time, the provision of the notches 10 allows the shape of the first support 1 to match the end of the stator teeth facing the inside of the stator, increasing the space factor of the stator and simultaneously making the overall connection tighter.

[0308] Specifically, the notch 10 is a flat, non-through structure.

[0309] Furthermore, the side of the notch 10 that is closer to the top of the first support 1 is flush with the top of the auxiliary slot 30 .

[0310] In this embodiment, the side of the notch 10 closest to the top of the first support 1 is flush with one side of the top of the auxiliary slot 30, which further ensures the relief effect of the notch 10 on the coil and increases the space factor of the stator.

[0311] Example 12: As shown in Figures 1 to 5, according to one embodiment of the present application, in addition to the above embodiments, the insulating framework further includes a mark 29 provided on at least one of the second support 2 and the first support 1, the mark 29 corresponding to the width of the notch 2400 of the terminal accommodating portion 24 and the width of the auxiliary slot 30 of the third support 3.

[0312] In this embodiment, the insulating framework further includes marks 29 disposed on at least one of the second support 2 and the first support 1. As can be understood, when winding different stators, the marks 29 correspond to different coil diameters, different widths of the auxiliary slots 30, and different widths of the notches 2400. That is, the coil diameter corresponds one-to-one with the width of the notches 2400 and the width of the auxiliary slots 30. Therefore, the coil diameter changes synchronously with the width of the notches 2400 and the width of the auxiliary slots 30. Therefore, in the embodiment presented in the present application, marks 29 are disposed on the insulating framework, and the marks 29 correspond one-to-one with the coil diameter, the width of the notches 2400, and the width of the auxiliary slots 30. In this way, different insulating frameworks can be selected according to the marks 29 based on different coil diameters. Specifically, different insulating frameworks correspond to different widths of the notches 2400 and the auxiliary slots 30. Therefore, insulating frameworks with various dimensional specifications can be adapted to coils of different sizes.

[0313] Specifically, the width of the notch 2400 and the yoke width of the auxiliary slot 30 can have various dimensions, which can be selected and used according to the actual situation.

[0314] Specifically, the mark 29 may be a number, an alphabet, or a symbol having an equivalent function.

[0315] In a specific application, the mark 29 is placed on the terminal receiving portion 24 of the second support 2, and the mark 29 is placed on the top of the terminal receiving portion 24 so that the user can easily recognize it.

[0316] Example 13: As shown in Figures 10 and 11, according to a second aspect of the present application, a stator is further provided, which includes a stator core 4 including a plurality of split cores connected in series, each split core including a teeth portion, and the teeth portions of two adjacent split cores together surrounding a stator slot; an insulating framework as provided in any one of the first aspects, in which there are multiple insulating frameworks, each split core is provided with an insulating framework at both ends, and a third support 3 is installed opposite the teeth portion; and a winding 5 wound around the teeth portion and the insulating framework.

[0317] The stator provided in the second aspect of the present application includes an insulating framework according to any of the embodiments of the first aspect, and therefore has all the beneficial effects of the insulating framework.

[0318] The stator further includes a stator core 4, which includes a plurality of sequentially connected split cores, each split core including teeth, with a stator slot for accommodating windings 5 enclosed between the teeth of two adjacent split cores, with an insulating framework installed at both ends of each split core, allowing the windings 5 to be wound around the teeth and insulating framework and ensuring insulation performance. At the same time, this winding method allows the windings 5 to be electrically connected to the same phase windings 5 only through the insulating framework, eliminating the need for additional structures to achieve electrical connection, further reducing the axial height of the stator and making the ends of the stator more compact.

[0319] Furthermore, the winding 5 includes multiple coils, one coil wound around one split core and an insulating framework at both ends of the split core, the coil including a winding start portion and a winding end portion, and the wire slots 20 are used to accommodate the winding start portion and the winding end portion.

[0320] In this embodiment, the winding 5 includes multiple coils, and one split core and its two ends are formed into a core component, where one coil is wound around each core component. After the winding of each coil is completed, the multiple core components are rolled up to form a stator, which further improves the space factor and prevents scratches on the insulating layer on the coil surface.

[0321] Here, the coil includes a start portion and an end portion, and wire slots 20 are used to accommodate the start portion and the end portion, ensuring tightness of the coil windings.

[0322] Specifically, the winding start portion is engaged in the wire slot 20 at one axial end of the stator core 4 and extends to the other end of the stator core 4, starting from the side of the insulating framework far from the wire slot 20, and the winding end portion is located on the side of the insulating framework closer to the wire slot 20. The winding end portion is then wound around the stepped portion 28, passing over the upper surface of the stepped portion 28 and extending below the protrusion 26, and then extending into the wire slot 20 and pre-fixed within the wire slot 20. After all the coils have been wound, the multiple split cores are rolled to form a stator. Compared with the prior art, the embodiment proposed in this application not only improves the space factor of the stator but also prevents damage to the insulation layer of the coil itself.

[0323] The stator further includes an insulating cover plate 6 located on the side of the insulating framework remote from the stator core 4 and engaging with a projection 26 of the insulating framework.

[0324] In this embodiment, the insulating framework further includes an insulating cover plate 6 installed on the side of the insulating framework away from the stator core 4. The installation of the insulating framework can realize rounded insulation protection for both ends of the coils and improve the safety performance of the stator. Here, the insulating cover plate 6 is connected to the protrusions 26 of the insulating framework to fix the insulating cover plate 6, making the overall structure of the stator more compact and achieving effective engagement between the two.

[0325] Furthermore, the insulating cover plate 6 engages with the projections 26 of the insulating framework.

[0326] In a specific application, as shown in Fig. 12, a snap 60 is installed on the insulating cover plate 6, and the snap 60 engages with the protrusion 26. As can be seen, the length of the protrusion 26 is shorter than the length of the terminal receiving portion 24, so that the engagement between the snap 60 and the protrusion 26 is guaranteed.

[0327] Furthermore, any of the split cores includes a plurality of punched pieces that are laminated and distributed along the axial direction of the stator core 4.

[0328] In this embodiment, each split core is configured to include a plurality of punched pieces that are stacked and distributed along the axial direction of the stator core 4. In this manner, overlapping portions are formed on the peripheral edges of the punched pieces. When the plurality of punched pieces are stacked and distributed along the axial direction of the core, overlapping gaps are limited between adjacent punched pieces and are formed in the stator slots, making it easy for the windings 5 to be wound around the teeth of the stator core 4 and located within the stator slots.

[0329] Specifically, the punched piece is a silicon steel plate.

[0330] Furthermore, two adjacent split cores are rotatably connected by an overlapping portion.

[0331] In this embodiment, two adjacent split cores are rotatably connected by an overlapping portion, that is, the two connected split cores are rotatable relative to each other.

[0332] By connecting two adjacent split cores rotatably through an overlapping portion, one split core can be rotated around the other split core, with the connection point of the overlapping portion as the center of the circle. This connection method is simple and reliable, and allows the operator to easily adjust the external shape and structure of the stator core 4, and the position of the split cores can be adjusted according to usage needs.

[0333] Furthermore, the stator core 4 includes a teeth portion and a yoke portion, and the stator core 4 has at least a first state and a second state, in which in the first state, the multiple split cores are rolled up to form a first ring, and the teeth portion is located inside the yoke portion, and in the second state, the multiple split cores are expanded in an approximately linear manner.

[0334] In this embodiment, the stator core 4 has a first state, which is a normal state after the stator core 4 is wound with windings 5. In the first state, the multiple split cores are rolled into a first annular shape, and the teeth are located inside the yoke. In this state, the windings 5 are wound around stator slots formed by adjacent teeth, and the windings 5 are close to the inside of the stator core 4. Two adjacent stator cores 4 are rotatably connected by overlapping portions installed on the outer yoke portions, and are surrounded together to form a circular stator core 4.

[0335] Stator core 4 further has a second state in which two adjacent split cores are rotatably connected, so that when two adjacent split cores in stator core 4 move relative to each other, the multiple split cores can unfold in a substantially linear fashion. After unfolding, the teeth of each split core are distributed in a substantially linear fashion, and because stator core 4 is in an unfolded state, the space in the stator slot between the two teeth is increased compared to the first state, making it easier for the operator to wind winding 5.

[0336] By placing the stator core 4 in the second state, the teeth can be distributed in a substantially linear manner and the space of the stator slot is increased, making it easier for the operator to wind the windings 5. Once the winding operation of the windings 5 is completed, the stator core 4 is returned to the first state, and each of the divided cores is enclosed together by the circular stator core 4, making the structure of the stator core 4 more stable and reliable.

[0337] Furthermore, in the second state, the two split cores at both ends are connected after being rolled, and specifically, the two split cores can be welded after being rolled.

[0338] As will be understood, in the second state, the stator core 4 assumes a substantially straight shape, including the stator core 4 assuming a straight shape or the stator core 4 having a certain degree of arc.

[0339] Furthermore, the multiple punched pieces include first punched piece layers and second punched piece layers arranged alternately, an overlapping portion is arranged on a first side of the first punched piece layer, the overlapping portion on the first punched piece layer protrudes from the second punched piece layer, two adjacent first punched piece layers together enclose an overlapping gap, an overlapping portion is arranged on a second side of the second punched piece layer, the overlapping portion on the second punched piece layer protrudes from the first punched piece layer, two adjacent second punched piece layers together enclose an overlapping gap, and the overlapping portion of one of the two adjacent split cores is inserted into the overlapping gap of the other split core.

[0340] In this embodiment, the plurality of punched pieces includes a first punched piece layer and a second punched piece layer, and the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the axial direction of the stator core 4. The first punched piece layer has an overlapping portion on a first side, and the overlapping portion on the first punched piece layer protrudes from the second punched piece layer. The plurality of first punched piece layers and the plurality of second punched piece layers are alternately arranged, and two adjacent first punched piece layers both protrude from the second punched piece layer located between the two adjacent first punched piece layers, thereby enclosing an overlapping gap between the two adjacent first punched piece layers. The second punched piece layer has an overlapping portion on a second side, that is, the overlapping portion of the second punched piece layer is located on a different side from the first punched piece layer. The overlapping portion on the second punched piece layer protrudes from the first punched piece layer, and a plurality of first punched piece layers and a plurality of second punched piece layers are alternately arranged, with each of two adjacent second punched piece layers protruding from the first punched piece layer located midway between the two adjacent second punched piece layers, so that an overlapping gap can also be enclosed between the two adjacent second punched piece layers.

[0341] As will be understood, when the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the circumferential direction of the stator core 4, the overlapping portions located on first sides of the plurality of first punched piece layers are alternately arranged with the overlapping portions located on second sides of the plurality of second punched piece layers. Furthermore, the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are respectively located on both sides of the split core and are arranged alternately.

[0342] An overlapping portion and an overlapping gap are provided on the adjacent sides of two adjacent split cores, and the overlapping portions located on the first side of the multiple first punched piece layers and the overlapping portions located on the second side of the multiple second punched piece layers are alternately arranged, and the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are alternately arranged, and the overlapping portion of one split core is inserted into the overlapping gap of the other split core, thereby realizing the connection between the two adjacent split cores.

[0343] By alternately arranging the first and second punched piece layers, with overlapping portions on different sides of the first and second punched piece layers and overlapping gaps on different sides, two adjacent split cores can be connected through the overlapping portions and overlapping gaps. Specifically, the overlapping portion of one split core is inserted into the overlapping gap of the other split core. This connection method is stable and reliable, allowing operators to quickly install and remove the stator core 4 and improving work efficiency. Furthermore, by using the same structure for multiple split cores, interconnection can be achieved, reducing the number of split core types, improving split core versatility, and reducing product costs.

[0344] Furthermore, the multiple punched pieces include first punched piece layers and second punched piece layers arranged alternately, an overlapping portion is arranged on a first side of the first punched piece layer, the overlapping portion on the first punched piece layer protrudes from the second punched piece layer, two adjacent first punched piece layers together enclose an overlapping gap, an overlapping portion is arranged on a second side of the second punched piece layer, the overlapping portion on the second punched piece layer protrudes from the first punched piece layer, two adjacent second punched piece layers together enclose an overlapping gap, and the overlapping portion of one of the two adjacent split cores is inserted into the overlapping gap of the other split core.

[0345] In this embodiment, the plurality of punched pieces includes a first punched piece layer and a second punched piece layer, and the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the axial direction of the stator core 4. The first punched piece layer has an overlapping portion on a first side, and the overlapping portion on the first punched piece layer protrudes from the second punched piece layer. The plurality of first punched piece layers and the plurality of second punched piece layers are alternately arranged, and two adjacent first punched piece layers both protrude from the second punched piece layer located between the two adjacent first punched piece layers, thereby enclosing an overlapping gap between the two adjacent first punched piece layers. The second punched piece layer has an overlapping portion on a second side, that is, the overlapping portion of the second punched piece layer is located on a different side from the first punched piece layer. The overlapping portion on the second punched piece layer protrudes from the first punched piece layer, and a plurality of first punched piece layers and a plurality of second punched piece layers are alternately arranged, with each of two adjacent second punched piece layers protruding from the first punched piece layer located midway between the two adjacent second punched piece layers, so that an overlapping gap can also be enclosed between the two adjacent second punched piece layers.

[0346] As will be understood, when the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the circumferential direction of the stator core 4, the overlapping portions located on first sides of the plurality of first punched piece layers are alternately arranged with the overlapping portions located on second sides of the plurality of second punched piece layers. Furthermore, the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are respectively located on both sides of the split core and are arranged alternately.

[0347] An overlapping portion and an overlapping gap are provided on the adjacent sides of two adjacent split cores, and the overlapping portions located on the first side of the multiple first punched piece layers and the overlapping portions located on the second side of the multiple second punched piece layers are alternately arranged, and the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are alternately arranged, and the overlapping portion of one split core is inserted into the overlapping gap of the other split core, thereby realizing the connection between the two adjacent split cores.

[0348] By alternately arranging the first and second punched piece layers, with overlapping portions on different sides of the first and second punched piece layers and overlapping gaps on different sides, two adjacent split cores can be connected through the overlapping portions and overlapping gaps. Specifically, the overlapping portion of one split core is inserted into the overlapping gap of the other split core. This connection method is stable and reliable, allowing operators to quickly install and remove the stator core 4 and improving work efficiency. Furthermore, by using the same structure for multiple split cores, interconnection can be achieved, reducing the number of split core types, improving split core versatility, and reducing product costs.

[0350] The motor provided in the third aspect of the present application includes the stator provided in the first aspect, and therefore has all the beneficial effects of the stator.

[0351] Furthermore, the motor further includes a rotor, which is disposed inside the stator and rotates in cooperation with the stator, and is capable of outputting torque.

[0355] The vehicle provided in the fifth aspect of the present application includes the compressor provided in the fourth aspect, and thus has all the beneficial effects of the compressor.

[0356] Specific examples: As shown in FIGS. 1 to 11, the embodiments provided herein provide an insulating framework for use in a stator, the stator including windings 5, the windings 5 being wound around the insulating framework.

[0357] Here, the main body of the insulating framework is arranged in a substantially U-shape, and the insulating framework includes a first support 1, a second support 2, and a third support 3. The second support 2, the first support 1, and the third support 3 have a common reference plane, and the height of the second support 2 is greater than that of the first support 1, and the height of the first support 1 is greater than that of the third support 3, along the reference plane, and they commonly form a winding accommodating section.

[0358] The surface of the first support 1 that is closer to the winding housing portion is substantially flat, and the surface on the other side is arc-shaped.

[0359] 8 and 9, the second support 2 extends mainly on both sides in a direction substantially perpendicular to the reference plane, and has connecting protrusions 27 on the second support 2 for cooperating with the stator core 4 to fix the insulating framework to the stator core 4. When viewed in a direction perpendicular to the reference plane, the protrusions 26, wire slots 20, and terminal accommodating portions 24 are sequentially distributed.

[0360] The third support 3 extends from the reference plane to one side of the winding housing, and has auxiliary slots 30 on the surface closer to the winding housing to assist in arranging the coils during winding, the auxiliary slots 30 extending in an array toward the reference plane.

[0361] The protrusion 26 has a protrusion extending along the reference plane direction, the protrusion is inclined in a direction perpendicular to the reference plane, and the outermost shape edge of the protrusion 26 is lower than the outermost shape edge of the terminal accommodating portion 24.

[0362] The wire slot 20 is divided into an upper half and a lower half. The upper half is hollow, while the lower half has a sloped shape. A step surface separates the upper and lower halves. The upper edge of the slope extends from the step surface to the lower edge. The lower edge is approximately flush with the surface of the auxiliary slot 30 of the third support 3.

[0363] Notches 2400 for accommodating the conductor wire are arranged on both sides of terminal accommodating section 24, the upper half of notch 2400 being a sloped opening and the lower half being generally U-shaped, and a accommodating groove 240 having a generally hollow rectangular area for accommodating the crimp terminal is provided in the center of terminal accommodating section 24. Adhesive overflow grooves 242 are provided on both sides of notch 2400, and adhesive overflow grooves 242 are shaped like depressions or depression-like depressions due to localized protrusions or semi-protrusions.

[0364] Furthermore, the stepped surface of the wire slot 20 is lower than the lower surface of the outer projection 26 .

[0365] Furthermore, the width of the wire slot 20 is greater than the width of the notch 2400 of the outer terminal receiving portion 24 .

[0366] Furthermore, the side of the wire slot 20 closer to the terminal accommodating portion 24 is substantially flush with the side of the third support 3 closer to the protrusion 26 .

[0367] Furthermore, the terminal accommodating portion 24 has a mark 29 in a direction parallel to the reference plane, and the mark 29 may be a number, an alphabet, or a symbol having an equivalent function. The mark 29 is formed in such a way that, when the wire diameter of the winding wire changes, the width of the notch 2400 in the terminal accommodating portion 24 changes in synchronization with the width of the auxiliary slot 30.

[0368] Furthermore, a step portion 28 is provided on the side of the protrusion 26 away from the wire slot 20, and the width of the step portion 28 is smaller than the width of the wire slot 20.

[0369] Furthermore, the sum of the widths of the multiple auxiliary slots 30 is equal to or less than the width of the main body of the third support 3. When the auxiliary slot 30 naturally extends along the outer surface of the third support 3, it is directly and flatly cut by the side surface of the third support 3, and the highest point where the two extend and intersect is called the side height of the auxiliary slot 30.

[0370] Furthermore, a flat or non-through cutout 10 is provided in the first support 1 .

[0371] Furthermore, the height of the notch 10 matches the side height of the auxiliary slot 30 .

[0372] Furthermore, the number of wire slots 20 is only one. Compared to the prior art, the present invention requires only one wire slot 20, and further accommodates the winding start and winding end simultaneously within the wire slot 20, making the coil winding more compact.

[0373] Furthermore, the material of the insulating framework is an insulating material that can withstand temperatures of 120° C. or higher. Specifically, the material of the insulating framework is an insulating material that can withstand temperatures of 120° C. or higher for a long period of time.

[0374] Furthermore, the insulating framework is applied to a stator, the stator is applied to a motor, and the compressor includes the motor.

[0375] Specifically, the vehicle includes a vehicle body and a compressor, and the compressor is installed inside the vehicle body.

[0376] Example 17: As shown in FIGS. 1 and 2, according to one embodiment of a sixth aspect of the present application, the present application provides an insulating framework including a first support 1, a second support 2, and a third support 3.

[0377] Specifically, the second support 2 is disposed opposite the first support 1, and a terminal accommodating portion 24 is provided on the side of the second support 2 away from the first support 1, and the terminal accommodating portion 24 includes an accommodating groove 240 and an adhesive overflow groove 242. Here, the accommodating groove 240 is used to accommodate a crimp terminal, and a notch 2400 is provided in the opposing side wall of the accommodating groove 240 along the first direction, and the adhesive overflow groove 242 is located on at least one side of the accommodating groove 240 along the first direction, and the adhesive overflow groove 242 is connected to the notch 2400, and the third support 3 is disposed between the first support 1 and the second support 2 and is connected to the first support 1 and the second support 2.

[0378] The insulating framework provided herein includes a first support 1, a second support 2, and a third support 3, where the second support 2 and the first support 1 are disposed opposite each other, and the third support 3 is disposed between the first support 1 and the second support 2, with one end of the third support 3 connected to the first support 1 and the other end connected to the second support 2, thereby connecting the first support 1, the second support 2, and the third support 3 together. The insulating framework further includes a terminal accommodating portion 24, which is disposed on the second support 2, and a crimp terminal is disposed in the terminal accommodating portion 24. Coils of the same phase are connected in series by the crimp terminal in the terminal accommodating portion 24. The terminal accommodating portion 24 is disposed on the side of the second support 2 away from the first support 1, thereby avoiding occupancy of the coil winding space. At the same time, the terminal receiving portions 24 and the wire slots 20 are distributed along the first direction, which facilitates winding of the coils and serial connection of the coils of the same phase. In addition, by arranging the terminal receiving grooves 240 in the insulating framework, it is possible to avoid placing other structures for realizing the electrical connection of the same phase above the insulating framework, and further reduce the overall size of the stator.

[0379] Here, the first direction is the circumferential direction of the stator core 4.

[0380] Furthermore, as shown in Figures 1 and 3, the terminal accommodating portion 24 includes an accommodating groove 240 and an adhesive overflow groove 242. The accommodating groove 240 is used to accommodate the crimp terminal of the stator. Here, a notch 2400 is formed in the accommodating groove 240, and the winding start and end portions of the in-phase coil extend from the notch 2400 on one side of the accommodating groove 240 into the accommodating groove 240, which plays a role in positioning the coil and ensuring the stability of the coil, while at the same time realizing the electrical connection of the in-phase coil via the crimp terminal.

[0381] In addition, the adhesive overflow groove 242 is installed on at least one side of the accommodating groove 240 and communicates with the notch 2400. In this way, after the same-phase coils are electrically connected by the connecting terminals, the coils are sealed with sealant in the accommodating groove 240 and the notch 2400, improving the safety performance of the coil. Furthermore, by installing the adhesive overflow groove 242, excess sealant is received in the adhesive overflow groove 242 during the process of sealing the crimp terminal with sealant, so that the sealant does not overflow outside the terminal accommodating portion 24, and good sealing of the coil is achieved.

[0382] In a specific application, two notches 2400 are provided in the receiving groove 240, and the two notches 2400 are respectively provided on two side walls in the first direction of the receiving groove 240. Similarly, the number of adhesive overflow grooves 242 is two, and the two adhesive overflow grooves 242 are respectively provided corresponding to the two notches 2400, so that when sealing is performed at the two notches 2400, the adhesive overflow grooves 242 can prevent the sealant from overflowing from either of the two notches 2400.

[0383] As can be seen, when sealing the crimp terminal and the cut end of the conductor, if a low-viscosity sealant is used, the sealant will tend to flow down the side walls of the receiving groove 240, making it difficult to completely seal the crimp terminal and the cut end of the conductor. If a high-viscosity sealant is used, the sealant will not flow well and the notch 2400 of the receiving groove 240 will be narrow, making it very difficult to completely cover the crimp terminal and the cut end of the conductor. Therefore, the present invention provides an adhesive overflow groove 242 to prevent the sealant from overflowing and to completely seal the crimp terminal and the cut end of the coil conductor. Furthermore, when sealing the end of the coil, good sealing of the end of the coil can be achieved.

[0384] Example 18: As shown in Figures 2 and 3, according to one embodiment of the present application, in addition to the above embodiments, the terminal accommodating portion 24 further includes an adhesive overflow pad 244 provided on both sides of the accommodating groove 240 along the first direction, and a boss 246 provided on the adhesive overflow pad 244, and at least the boss 246 surrounds the adhesive overflow groove 242 together with the adhesive overflow pad 244.

[0385] In this embodiment, the terminal accommodating portion 24 further includes an adhesive overflow pad 244 and a boss 246, and the adhesive overflow pads 244 are installed on both sides of the accommodating groove 240, i.e., the terminal accommodating portion 24 has adhesive overflow pads 244 protruding on both sides of the accommodating groove 240 in the first direction. The boss 246 is installed on the adhesive overflow pad 244, so that at least the adhesive overflow pad 244 and the boss 246 surround the adhesive overflow groove 242, and the adhesive overflow groove 242 surrounds at least a portion of the notch 2400. Furthermore, when sealant is poured into the accommodating groove 240 and the notch 2400 to seal them, excess sealant can flow into the adhesive overflow groove 242, preventing the sealant from overflowing from the terminal accommodating portion 24.

[0386] As will be appreciated, the crimp terminals penetrate the coils, thereby connecting the in-phase coils.

[0387] In a specific application, the crimp terminal is a break-through terminal, so that when the crimp terminal is pressed against the coil in the receiving groove 240, it can break through the insulating coating on the surface of the coil, thereby realizing electrical connection of the coils in the same phase and realizing quick connection.

[0388] Example 19: As shown in Figures 1 and 3, according to one embodiment of the present application, in addition to the above embodiments, the boss 246 further includes a first boss 2460 arranged on a first side of the accommodating groove 240 along the first direction and located on the side of the notch 2400 away from the first support 1, and a second boss 2462 arranged on a second side of the accommodating groove 240 along the first direction, surrounding the adhesive overflow groove 242 together with the second support 2, the accommodating groove 240 and the adhesive overflow platform 244, with a notch provided between the accommodating groove 240 and the second boss 2462.

[0389] In this embodiment, the boss 246 includes a first boss 2460 and a second boss 2462, and the first boss 2460 and the second boss 2462 are respectively installed on the adhesive overflow pads 244 on both sides of the accommodating groove 240, where the first boss 2460 is installed on the side of the accommodating groove 240 away from the terminal accommodating portion 24 and is located on the side of the notch 2400 away from the first support 1, so that when the sealant is injected into the accommodating groove 240 and the notch 2400, the excess sealant is received by the first boss 2460, preventing the sealant from overflowing. The second boss 2462 is located on the side of the accommodating groove 240 closer to the terminal accommodating portion 24, and the second boss 2462 surrounds the adhesive overflow groove 242 together with the surface of the second support 2 and the outer wall surface of the accommodating groove 240, whereby the area between the end of the second boss 2462 and the wall surface of the accommodating groove 240 is not completely closed but has a notch, thereby facilitating cutting and sealing of the end of the coil winding.

[0390] In a specific application, a wire slot 20 is provided at the bottom of the first boss 2460, and the wire slot 20 is positioned opposite the notch 2400, so that the coil can be further fixed within the wire slot 20 and the robustness of the coil can be improved.

[0391] Furthermore, the size of the notch is small, which further prevents the sealant from leaking out. Specifically, the width of the notch is 1 mm or more and 5 mm or less.

[0392] Example 20: As shown in FIG. 1, according to one embodiment of the present application, in addition to the above embodiments, the notch 2400 further includes a first passage 2402 and a second passage 2404 that communicate with each other, the first passage 2402 is located at the top of the second passage 2404, and the side walls of the first passage 2402 are arranged to gradually widen on both sides of the first passage 2402.

[0393] In this embodiment, the notch 2400 includes a first passage 2402 and a second passage 2404 that are connected to each other, i.e., the notch 2400 is divided into an upper half and a lower half, where the first passage 2402 is located in the upper half and the second passage 2404 is located in the lower half, the upper and lower halves are connected, and the side walls of the first passage 2402 are gradually widened, making it easier to pass the coil through the notch 2400. At the same time, the upper half of the notch 2400 is inclined, making it easier to inject the sealant, and the sealant can flow along the inclined wall surface toward the bottom of the slot in the notch 2400, improving the sealing effect of the sealant on the cut cross section of the coil.

[0394] In a specific application, the notch 2400 is generally U-shaped, the sidewalls of the first passageway 2402 are beveled, and the sidewalls of the first passageway are generally flat.

[0395] Example 21: As shown in Figures 4, 5 and 6, according to one embodiment of the present application, in addition to the above embodiments, the insulating framework further includes a protrusion 26, which is provided on the side of the second support 2 away from the first support 1, and the protrusion 26 and the terminal accommodating groove 240 are sequentially arranged along the first direction.

[0396] In this embodiment, the insulating framework further includes a protrusion 26, which is installed on the second support 2 and located on the side of the second support 2 away from the first support 1 and the third support 3, and the protrusion 26 and the terminal accommodating portion 24 are installed sequentially along the first direction. The installation of the protrusion 26 can serve to regulate the position of the coil and prevent the coil from slipping out. Specifically, the installation of the protrusion 26 can prevent the end of the coil from slipping out, improving the fixation of the coil.

[0397] In a specific application, the stator includes a stator core 4, an insulating framework, and an insulating cover plate 6. The insulating framework is installed on both ends of the stator core 4, and the insulating cover plate 6 is installed on both ends of the insulating framework away from the stator core 4. The insulating cover plate 6 serves an insulating role and improves the safety performance of the motor. Here, the protrusions 26 engage with the insulating cover plate 6, connecting the insulating framework and the insulating cover plate 6 and improving the reliability of the connection between the insulating cover plate 6 and the insulating framework.

[0398] As will be appreciated, both the insulating cover plate 6 and the insulating framework are made of insulating material.

[0399] Specifically, the wire slot 20 is disposed in the second support 2, and the protrusion 26, the wire slot 20, and the terminal accommodating portion 24 are sequentially disposed along the first direction. The wire slot 20 includes a bottom wall, which is inclined toward the bottom of the second support 2 to form an inclined portion 22, where the inclined portion 22 is located on the side closer to the first support 1. In this way, when a wire is wound around the insulating framework, the coil extends from the side of the wire slot 20 away from the first support 1 into the wire slot 20 and then along the inclined portion 22 to the bottom of the first support 1, which facilitates coil winding. Moreover, the wire slot 20 can pre-fix the coil, making the coil winding more compact, improving coil fixation, and improving the space factor of the stator core 4.

[0400] In a specific application, the insulating framework is applied to a stator, which includes a stator core 4, a coil, and the insulating framework, where the insulating framework is installed on both axial ends of the stator core 4, and the coil is wound around the insulating framework and the stator core 4. The first support 1, the second support 2, and the third support 3 together surround a winding receiving portion for receiving the coil, and the stator core 4 is pulled through the wire slot 20, so that the coil is inclined downward along the inclined portion 22 and the coil is wound more tightly.

[0401] As can be seen, the wire slot 20 includes an opening and a bottom wall disposed opposite the opening, and a portion of the bottom wall of the wire slot 20 is disposed at an angle toward the bottom of the second support 2 to form a sloped portion 22, and the sloped portion 22 is disposed on the side of the wire slot 20 facing the first support 1, i.e., the sloped portion 22 is disposed on the inside of the first support 1. In other words, the upper half of the wire slot 20 is approximately U-shaped, the opening is located at the top of the U-shape, and the lower half of the wire slot 20 is sloped, which makes the coil more compact when passing it through and improves the fixation of the coil winding.

[0402] Specifically, when the insulating framework is applied to a stator, the first support 1 is close to the inside of the stator core 4, the second support 2 is close to the outside of the stator core 4, and the third support 3 is connected to and located between the first support 1 and the second support 2.

[0403] One coil is wound around each of the split cores, and each coil includes a winding start portion and a winding end portion. After winding is completed, the winding end portion extends from the bottom of the protrusion 26 into the wire slot 20, and the position of the coil is regulated by the wire slot 20.

[0404] As can be understood, along the first direction, the wire slot 20 includes a first side and a second side, and the first side of the wire slot 20 and the second side of the wire slot 20 are oppositely disposed opposite sides of the wire slot 20, where the side of the wire slot 20 closer to the terminal accommodating portion 24 is the first side of the wire slot 20, and the side of the wire slot 20 closer to the protrusion 26 is the second side of the wire slot 20.

[0405] Additionally, the width of the wire slot 20 is greater than the width of the notch 2400 .

[0406] In this embodiment, both the beginning and end of the coil are positioned within the notch 2400, making it easier for the coil to enter the slot, and because the width of the wire slot 20 is greater than the width of the notch 2400, the beginning and end of the coil are more tightly connected to the notch 2400 when entering the notch 2400, improving the fixation of the notch 2400 to the coil.

[0407] In a specific application, the width of the wire slot 20 is the width of the wire slot 20 along the first direction, and the width of the notch 2400 is the width of the notch 2400 along the second direction. Specifically, the wire slot 20 and the notch 2400 are both approximately U-shaped, and the width of the wire slot 20 and the width of the notch 2400 are the distance between the left and right sidewalls of the U-shape.

[0408] By setting the width of the notch 2400 and the wire slot 20 as described above, the start and end of the coil can be accommodated simultaneously within the notch 2400, while improving the compactness of the coil.

[0409] Example 22: As shown in FIGS. 4 to 7, according to one embodiment of the present application, in addition to the above-described embodiment, at least a part of the top wall of the protrusion 26 is inclined toward the bottom of the second support 2.

[0410] In this embodiment, at least a portion of the top wall of the protrusion 26 is inclined toward the bottom of the second support 2, thereby reducing the material used for the protrusion 26 and reducing production costs, while avoiding interference with other structures when the insulating framework is used in combination with other structures.

[0411] In a specific application, the cross section of the protrusion 26 is generally triangular.

[0412] Example 23: According to one embodiment of the present application, in addition to the above-described embodiment, the length by which the terminal accommodating portion 24 protrudes from the second support 2 is greater than the length by which the protruding portion 26 protrudes from the second support 2 .

[0413] In this embodiment, both the terminal accommodating portion 24 and the protrusion protrude from the second support 2 away from the first support 1, and the protrusion length from the second support 2 is shorter than the protrusion length from the second support 2 of the terminal accommodating portion 24. In this way, when the insulating framework is connected to the insulating cover plate 6, interference with the connection between the two is avoided, and the connection reliability between the two is ensured.

[0414] As can be seen, the second support 2, the third support 3 and the first support 1 are distributed sequentially along the second direction, and the length of the protrusion along the second direction is smaller than the length of the terminal accommodating portion 24.

[0415] As will be understood, the second direction is the radial direction of the stator core 4.

[0416] Example 24: According to one embodiment of the present application, in addition to the above embodiment, the surface of the protrusion 26 closer to the bottom of the second support 2 is located on the side of the bottom wall of the wire slot 20 away from the bottom of the second support 2.

[0417] In this embodiment, the surface of the protrusion 26 closest to the bottom of the second support 2 is located on the side of the bottom wall of the wire slot 20 that is farther from the bottom of the second support 2. With this arrangement, the surface of the protrusion 26 closest to the bottom of the second support 2 is higher than the bottom wall of the wire slot 20, i.e., the bottom wall of the wire slot 20 is lower than the lower surface of the protrusion 26. Furthermore, the end of the coil is wound into the wire slot 20 from the side of the protrusion 26 that is farther from the wire slot 20, which prevents the coil from bending in the wire slot 20 and makes the coil routing tighter.

[0418] Specifically, the difference in distance between the underside of the protrusion 26 and the bottom wall of the wire slot 20 is equal to or greater than the diameter of the conductor wire in the coil. As will be appreciated, a length of conductor wire is wound around a split core and an insulating framework to form a coil.

[0419] Example 25: As shown in Figures 5 and 9, according to one embodiment of the present application, in addition to the above embodiment, the insulating framework further includes a step portion 28 provided on the second support 2 and located on the side of the protrusion portion 26 away from the terminal accommodating portion 24.

[0420] In this embodiment, the insulating framework further includes a stepped portion 28, which is attached to the second support 2 and is used to support the coil, specifically, the stepped portion 28 is used to support the end of the coil, thereby improving the tightness of the coil winding.

[0421] Specifically, the step portion 28 is located on the side of the protrusion 26 away from the wire slot 20, and thus the end of the coil is wound from the upper surface of the step portion 28 below the protrusion 26 and further extends into the wire slot 20, which fixes the end of the coil.

[0422] Example 26: As shown in Figures 1 to 7, according to one embodiment of the present application, in addition to the above embodiments, a plurality of auxiliary slots 30 are provided in the third support 3, and any of the auxiliary slots 30 extends along the first direction, and the plurality of auxiliary slots 30 are distributed along both directions from the first support 1 to the second support 2, and the first support 1, the third support 3 and the second support 2 are distributed sequentially along the second direction.

[0423] In this embodiment, auxiliary slots 30 are provided on the third support 3, and there are a plurality of auxiliary slots 30. The coil is fixed by the auxiliary slots 30, thereby improving the tightness and stability of the coil winding. Here, each auxiliary slot 30 extends along a first direction, and the plurality of auxiliary slots 30 are distributed in an array along a second direction, and the coil is wound on the insulating framework through the auxiliary slots 30.

[0424] Specifically, the auxiliary slot 30 is installed on the upper surface of the third support 3, and when the auxiliary slot 30 naturally extends along the outer surface of the third support 3, it is cut directly and flat by the side of the third support 3.

[0425] Specifically, the second direction is the radial direction of the stator.

[0426] Example 27: As shown in FIG. 4, according to one embodiment of the present application, in addition to the above embodiment, the edge of the inclined portion 22 close to the bottom of the second support 2 is substantially flush with the slot bottom of the auxiliary slot 30.

[0427] In this embodiment, the edge of the inclined portion 22 near the bottom of the second support 2 is approximately flush with the slot bottom of the auxiliary slot 30, preventing the coil from bending and ensuring tightness of the coil winding.

[0428] As will be understood, the edge of the inclined portion 22 closest to the bottom of the second support 2 is the lower edge of the inclined portion 22. The lower edge of the inclined portion 22 is approximately flush with the slot bottom of the auxiliary slot 30, that is, the lower edge of the inclined portion 22 is flush with the slot bottom of the auxiliary slot 30, or the lower edge of the inclined portion 22 is slightly higher than the slot bottom of the auxiliary slot 30.

[0429] Example 28: According to one embodiment of the present application, in addition to the above-described embodiment, the wall surface of the wire slot 20 near the terminal accommodating portion 24 is substantially flush with the wall surface of the third support 3 near the wire slot 20 .

[0430] In this embodiment, the wall surface of the wire slot 20 near the terminal accommodating portion 24 is approximately flush with the wall surface of the third support 3 near the wire slot 20. In this way, when the coil is wound from the wire slot 20 to the third support 3, the coil can be wound more tightly, improving the space factor of the stator core 4.

[0431] As can be seen, the wall surface near the terminal accommodating portion 24 of the wire slot 20 is approximately flush with the wall surface near the wire slot 20 of the third support 3, that is, the wall surface near the accommodating portion of the wire slot 20 is flush with the wall surface near the wire slot 20 of the third support 3, or there is a minute pitch between the wall surface near the accommodating portion of the wire slot 20 and the wall surface near the wire slot 20 of the third support 3.

[0432] Example 29: As shown in FIG. 7, according to one embodiment of the present application, in addition to the above embodiment, a notch 10 is further provided on the side of the first support 1 facing the second support 2, the notch 10 is located close to the bottom of the first support 1, and along the first direction, the notch 10 is located on both sides of the third support 3.

[0433] In this embodiment, a notch 10 is provided in the first support 1, and the notch 10 is located inside the first support 1, allowing the coil winding to escape and ensuring the tightness of the coil winding.

[0434] Specifically, the notch 10 is located on the side of the first support 1 facing the second support 2 and is installed close to the bottom of the first support 1; further, along the first direction, the notch 10 is installed on both sides of the third support 3, which not only further reduces the overall weight of the insulating framework and reduces production costs, but also prevents the third support 3 from excessively pressing on the coil and affecting the winding of the coil.

[0435] In a specific application, the wall surface of the first support 1 facing the second support 2 is generally flat, and the wall surface of the first support 1 facing away from the second support 2 is arc-shaped. When the insulating framework is applied to a stator, the first support 1 can surround a circle to accommodate the shape of the stator teeth, further facilitating rotor installation and movement. At the same time, the provision of the notches 10 allows the shape of the first support 1 to match the end of the stator teeth facing the inside of the stator, increasing the space factor of the stator and simultaneously making the overall connection tighter.

[0436] Specifically, the notch 10 is a flat, non-through structure.

[0437] Furthermore, the side of the notch 10 that is closer to the top of the first support 1 is flush with the top of the auxiliary slot 30 .

[0438] In this embodiment, the side of the notch 10 closest to the top of the first support 1 is flush with one side of the top of the auxiliary slot 30, which further ensures the relief effect of the notch 10 on the coil and increases the space factor of the stator.

[0439] Example 30: As shown in Figures 1 to 7, according to one embodiment of the present application, in addition to the above embodiments, the insulating framework further includes a mark 29 provided on at least one of the second support 2 and the first support 1, the mark 29 corresponding to the width of the notch 2400 and the width of the auxiliary slot 30 of the third support 3.

[0440] In this embodiment, the insulating framework further includes marks 29 disposed on at least one of the second support 2 and the first support 1. As can be understood, when winding different stators, the marks 29 correspond to different coil diameters, different widths of the auxiliary slots 30, and different widths of the notches 2400. That is, the coil diameter corresponds one-to-one with the width of the notches 2400 and the width of the auxiliary slots 30. Therefore, the coil diameter changes synchronously with the width of the notches 2400 and the width of the auxiliary slots 30. Therefore, in the embodiment presented in the present application, marks 29 are disposed on the insulating framework, and the marks 29 correspond one-to-one with the coil diameter, the width of the notches 2400, and the width of the auxiliary slots 30. In this way, different insulating frameworks can be selected according to the marks 29 based on different coil diameters. Specifically, different insulating frameworks correspond to different widths of the notches 2400 and the auxiliary slots 30. Therefore, insulating frameworks with various dimensional specifications can be adapted to coils of different sizes.

[0441] Specifically, the width of the notch 2400 and the yoke width of the auxiliary slot 30 can have various dimensions, which can be selected and used according to the actual situation.

[0442] Specifically, the mark 29 may be a number, an alphabet, or a symbol having an equivalent function.

[0443] In a specific application, the mark 29 is placed on the terminal receiving portion 24 of the second support 2, and the mark 29 is placed on the top of the terminal receiving portion 24 so that the user can easily recognize it.

[0444] Example 31: As shown in Figures 10 and 11, according to a seventh aspect of the present application, a stator is further provided, which includes a crimp terminal provided in the accommodating groove 240, a stator core 4 including a plurality of split cores connected in series, each split core including a tooth portion, and the tooth portions of two adjacent split cores together surrounding the stator slot, an insulating framework provided in any one of the first aspects, in which there are multiple insulating frameworks, each split core is provided with an insulating framework at both ends, and a third support 3 is installed opposite the tooth portion, and a winding 5 wound around the tooth portion and the insulating framework.

[0445] The stator provided in the seventh aspect of the present application includes the insulating framework of any of the above embodiments, and therefore has all the beneficial effects of the insulating framework.

[0446] The stator further includes a stator core 4, which includes a plurality of sequentially connected split cores, each split core including teeth. A stator slot for accommodating windings 5 is enclosed between the teeth of two adjacent split cores. An insulating framework is installed at both ends of each split core, allowing the windings 5 to be wound around the teeth and insulating framework, ensuring insulation performance. This winding method also allows the windings 5 to be electrically connected to the in-phase windings 5 using only the insulating framework, eliminating the need for additional structures to achieve the electrical connection. This also reduces the axial height of the stator and makes the stator end more compact. Here, crimp terminals are used to connect the in-phase windings 5 within the receiving grooves 240.

[0447] Furthermore, the winding 5 includes multiple coils, one coil wound around one split core and insulating frameworks at both ends of the split core, the coil includes a winding start portion and a winding end portion, and the wire slots 20 are used to accommodate the winding start portion and the winding end portion.

[0448] In this embodiment, the winding 5 includes multiple coils, and one split core and its two ends are formed into a core component, where one coil is wound around each core component. After the winding of each coil is completed, the multiple core components are rolled up to form a stator, which further improves the space factor and prevents scratches on the insulating layer on the coil surface.

[0449] Here, the coil includes a start portion and an end portion, and wire slots 20 are used to accommodate the start portion and the end portion, ensuring tightness of the coil windings.

[0450] Specifically, the winding start portion is engaged in the wire slot 20 at one end in the axial direction of the stator core 4 and extends to the other end of the stator core 4, starting from the side of the insulating framework far from the wire slot 20, and the winding end portion is located on the side of the insulating framework closer to the wire slot 20. The winding end portion is then wound around the stepped portion 28, passing over the upper surface of the stepped portion 28 and extending below the protrusion 26, then extending into the wire slot 20 and pre-fixed within the wire slot 20. After all the coils have been wound, the multiple split cores are rolled to form a stator. Compared with the prior art, the embodiment proposed in this application not only improves the space factor of the stator but also prevents damage to the insulation layer of the coil itself.

[0451] Further, the stator further includes an insulating cover plate 6, which is provided on both sides of the insulating framework, and has an escape groove provided in the insulating cover plate 6, which is installed corresponding to the mark 29 on the insulating framework and is used to escape the mark 29.

[0452] In this embodiment, the stator further includes an insulating cover plate 6, which is provided with a clearance groove for accommodating marks 29 on the insulating framework.

[0453] The stator further includes an insulating cover plate 6 located on the side of the insulating framework remote from the stator core 4 and engaging with a projection 26 of the insulating framework.

[0454] In this embodiment, the insulating framework further includes an insulating cover plate 6 installed on the side of the insulating framework away from the stator core 4. The installation of the insulating framework can realize rounded insulation protection for both ends of the coils and improve the safety performance of the stator. Here, the insulating cover plate 6 is connected to the protrusions 26 of the insulating framework to fix the insulating cover plate 6, making the overall structure of the stator more compact and achieving effective engagement between the two.

[0455] Furthermore, the insulating cover plate 6 engages with the projections 26 of the insulating framework.

[0456] 12, in a specific application, a snap 60 is installed on the insulating cover plate 6, and the snap 60 engages with the protrusion 26. As can be seen, the length of the protrusion 26 is shorter than the length of the terminal receiving portion 24, so that the engagement between the snap 60 and the protrusion 26 is guaranteed.

[0457] Furthermore, any of the split cores includes a plurality of punched pieces that are laminated and distributed along the axial direction of the stator core 4.

[0458] In this embodiment, each split core is configured to include a plurality of punched pieces that are stacked and distributed along the axial direction of the stator core 4. In this manner, overlapping portions are formed on the peripheral edges of the punched pieces. When the plurality of punched pieces are stacked and distributed along the axial direction of the core, overlapping gaps are limited between adjacent punched pieces and are formed in the stator slots, making it easy for the windings 5 to be wound around the teeth of the stator core 4 and located within the stator slots.

[0459] Specifically, the punched piece is a silicon steel plate.

[0460] Furthermore, two adjacent split cores are rotatably connected by an overlapping portion.

[0461] In this embodiment, two adjacent split cores are rotatably connected by an overlapping portion, that is, the two connected split cores are rotatable relative to each other.

[0462] By connecting two adjacent split cores rotatably through an overlapping portion, one split core can be rotated around the other split core, with the connection point of the overlapping portion as the center of the circle. This connection method is simple and reliable, and allows the operator to easily adjust the external shape and structure of the stator core 4, and the position of the split cores can be adjusted according to usage needs.

[0463] In the above embodiment, the stator core 4 further includes a teeth portion and a yoke portion, and the stator core 4 has at least a first state and a second state, in the first state, the multiple split cores are rolled up to form a first ring, the teeth portion is located inside the yoke portion, and in the second state, the multiple split cores are expanded in an approximately linear manner.

[0464] In this embodiment, the stator core 4 has a first state, which is a normal state after the stator core 4 is wound with windings 5. In the first state, the multiple split cores are rolled into a first annular shape, and the teeth are located inside the yoke. In this state, the windings 5 are wound around stator slots formed by adjacent teeth, and the windings 5 are close to the inside of the stator core 4. Two adjacent stator cores 4 are rotatably connected by overlapping portions installed on the outer yoke portions, and are surrounded together to form a circular stator core 4.

[0465] Stator core 4 further has a second state in which two adjacent split cores are rotatably connected, so that when two adjacent split cores in stator core 4 move relative to each other, the multiple split cores can unfold in a substantially linear fashion. After unfolding, the teeth of each split core are distributed in a substantially linear fashion, and because stator core 4 is in an unfolded state, the space in the stator slot between the two teeth is increased compared to the first state, making it easier for the operator to wind winding 5.

[0466] By placing the stator core 4 in the second state, the teeth can be distributed in a substantially linear manner and the space of the stator slot is increased, making it easier for the operator to wind the windings 5. Once the winding operation of the windings 5 is completed, the stator core 4 is returned to the first state, and each of the divided cores is enclosed together by the circular stator core 4, making the structure of the stator core 4 more stable and reliable.

[0467] Furthermore, in the second state, the two split cores at both ends are connected after being rolled, and specifically, the two split cores can be welded after being rolled.

[0468] As will be understood, in the second state, the stator core 4 assumes a substantially straight shape, including the stator core 4 assuming a straight shape or the stator core 4 having a certain degree of arc.

[0469] In the above embodiment, the plurality of punched pieces further includes first punched piece layers and second punched piece layers arranged alternately, an overlapping portion is arranged on a first side of the first punched piece layer, the overlapping portion on the first punched piece layer protrudes from the second punched piece layer, two adjacent first punched piece layers together enclose an overlapping gap, an overlapping portion is arranged on a second side of the second punched piece layer, the overlapping portion on the second punched piece layer protrudes from the first punched piece layer, two adjacent second punched piece layers together enclose an overlapping gap, and the overlapping portion of one of the two adjacent split cores is inserted into the overlapping gap of the other split core.

[0470] In this embodiment, the plurality of punched pieces includes a first punched piece layer and a second punched piece layer, and the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the axial direction of the stator core 4. The first punched piece layer has an overlapping portion on a first side, and the overlapping portion on the first punched piece layer protrudes from the second punched piece layer. The plurality of first punched piece layers and the plurality of second punched piece layers are alternately arranged, and two adjacent first punched piece layers both protrude from the second punched piece layer located between the two adjacent first punched piece layers, thereby enclosing an overlapping gap between the two adjacent first punched piece layers. The second punched piece layer has an overlapping portion on a second side, that is, the overlapping portion of the second punched piece layer is located on a different side from the first punched piece layer. The overlapping portion on the second punched piece layer protrudes from the first punched piece layer, and a plurality of first punched piece layers and a plurality of second punched piece layers are arranged alternately, with each of two adjacent second punched piece layers protruding from the first punched piece layer arranged midway between the two adjacent second punched piece layers, so that an overlapping gap can also be enclosed between the two adjacent second punched piece layers.

[0471] As will be understood, when the plurality of first punched piece layers and the plurality of second punched piece layers are alternately distributed along the circumferential direction of the stator core 4, the overlapping portions located on first sides of the plurality of first punched piece layers are alternately arranged with the overlapping portions located on second sides of the plurality of second punched piece layers. Furthermore, the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are respectively located on both sides of the split core and are arranged alternately.

[0472] An overlapping portion and an overlapping gap are provided on the adjacent sides of two adjacent split cores, and the overlapping portions located on the first side of the multiple first punched piece layers and the overlapping portions located on the second side of the multiple second punched piece layers are alternately arranged, and the overlapping gaps located between two adjacent first punched piece layers and the overlapping gaps located between two adjacent second punched piece layers are alternately arranged, and the overlapping portion of one split core is inserted into the overlapping gap of the other split core, thereby realizing the connection between the two adjacent split cores.

[0473] By alternately arranging the first and second punched piece layers, with overlapping portions on different sides of the first and second punched piece layers and overlapping gaps on different sides, two adjacent split cores can be connected through the overlapping portions and overlapping gaps. Specifically, the overlapping portion of one split core is inserted into the overlapping gap of the other split core. This connection method is stable and reliable, allowing operators to quickly install and remove the stator core 4 and improving work efficiency. Furthermore, by using the same structure for multiple split cores, interconnection can be achieved, reducing the number of split core types, improving split core versatility, and reducing product costs.

[0488] Specific examples: As shown in FIGS. 1 to 11, the embodiments provided herein provide an insulating framework for use in a stator, the stator including windings 5, the windings 5 being wound around the insulating framework.

[0489] Here, the main body of the insulating framework is arranged in a substantially U-shape, and the insulating framework includes a first support 1, a second support 2, and a third support 3. The second support 2, the first support 1, and the third support 3 have a common reference plane, and the height of the second support 2 is greater than that of the first support 1, and the height of the first support 1 is greater than that of the third support 3, along the reference plane, and they commonly form a winding accommodating section.

[0490] The surface of the first support 1 that is closer to the winding housing portion is substantially flat, and the surface on the other side is arc-shaped.

[0491] The second support 2 extends mainly on both sides in a direction substantially perpendicular to the reference plane, and has connecting protrusions 27 for cooperating with the stator core 4 to fix the insulating framework to the stator core 4. When viewed in a direction perpendicular to the reference plane, the protrusions 26, wire slots 20, and terminal accommodating portions 24 are sequentially distributed.
