Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to an insulating skeleton, a stator, a motor, a compressor and a vehicle. Background Art

[0002] Currently, electric motors include a stator and a rotor. The rotor and stator are constructed as a laminated iron core, with coils wound around each individual tooth in the stator slots. Typically, the coils are wound around the stator core, with an insulating frame between the stator core and the coils to insulate the coils.

[0003] To reduce the size of the compressor and increase its operating range, the motor must not only achieve high power density but also minimize the core height while maintaining the same output power. Furthermore, the motor's coils must be wound as compactly as possible on the insulating bobbin to maximize the stator's slot fill rate. However, the insulating bobbin used in related art lacks a corresponding structural component to effectively lock the coil lead wires, reducing the coil's securement. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention provides an insulating skeleton.

[0006] A second aspect of the present invention further provides a stator.

[0007] The third aspect of the present invention further provides a motor.

[0008] A fourth aspect of the present invention also provides a compressor.

[0009] A fifth aspect of the present invention also provides a vehicle.

[0010] In view of this, the first aspect of the present invention proposes an insulating skeleton, comprising: a first bracket; a second bracket, arranged opposite to the first bracket, and provided with a wire groove on the second bracket, the wire groove passes through the wall of the second bracket, and a part of the bottom wall of the wire groove is inclined toward the bottom of the second bracket to form an inclined portion, and the inclined portion is located on the side of the wire groove facing the first bracket; a third bracket, the third bracket is located between the first bracket and the second bracket and connected to the first bracket and the second bracket.

[0011] The insulating skeleton provided by the present invention includes a first bracket, a second bracket, and a third bracket. The second bracket and the first bracket are arranged in a relative manner. The third bracket is arranged between the first bracket and the second bracket, and one end of the third bracket is connected to the first bracket, and the other end of the third bracket is connected to the second bracket, so that the first bracket, the second bracket, and the third bracket are connected as a whole. Among them, a wire groove is provided on the second bracket, and the wire groove includes a bottom wall. The bottom wall of the wire groove is inclined toward the bottom of the second bracket to form an inclined portion. The inclined portion is located on the side close to the first bracket. In this way, when winding the wire through the insulating skeleton, the coil extends into the wire groove from the side of the wire groove away from the first bracket, and then extends along the inclined portion to the bottom of the first bracket, thereby facilitating the winding of the coil. At the same time, the wire groove can pre-fix the coil, making the winding of the coil more compact, improving the fixity of the coil, and improving the slot fill rate of the stator core.

[0012] In specific applications, the insulating frame is used in a stator, which includes a stator core, a coil, and the insulating frame. The insulating frame is positioned at both ends of the stator core's axis, and the coil is wound around the insulating frame and the stator core. The first, second, and third brackets together form a winding accommodating portion for the coil. The stator core feeds the wires through the wire slots, causing the coils to tilt downward along the inclined portion, allowing for a tighter winding arrangement.

[0013] Specifically, the first bracket, the second bracket and the third bracket are integrally formed.

[0014] It is understood that the wire trough includes an opening and a bottom wall disposed opposite the opening. A portion of the bottom wall of the wire trough is tilted toward the bottom of the second bracket to form an inclined portion. Furthermore, the inclined portion is disposed on the side of the wire trough facing the first bracket, i.e., the inclined portion is disposed inwardly of the first bracket. In other words, the upper portion of the wire trough is generally U-shaped, with the opening located at the top of the U-shape, and the lower portion of the wire trough is sloped, thereby making the coil more compact when passing the wire and improving the stability of the coil winding.

[0015] Specifically, when the insulating frame is applied to the stator, the first bracket is close to the inner side of the stator core, the second bracket is close to the outer side of the stator core, and the third bracket is connected to the first bracket and the second bracket and is located therebetween.

[0016] The above-mentioned insulating frame provided by the present invention may also have the following additional technical features:

[0017] In the above technical solution, the insulating frame further includes: a terminal accommodating portion, which is arranged on a side of the second bracket away from the first bracket and is used to accommodate the crimping terminal. Along the first direction, the terminal accommodating portion is located on the first side of the wire groove.

[0018] In this technical solution, the insulating skeleton also includes a terminal accommodating portion, which is arranged on the second bracket, and the crimping terminal is arranged in the terminal accommodating portion. The coils of the same phase are connected in the terminal accommodating portion through the crimping terminal, so that the coils of the same phase are connected in series. The terminal accommodating portion is arranged on the side of the second bracket away from the first bracket, thereby avoiding occupying the coil winding space. At the same time, the terminal accommodating portion and the wire groove are distributed along the first direction, which facilitates the winding of the coil and the series connection of the coils of the same phase. In addition, by arranging the terminal accommodating groove on the insulating skeleton, it is avoided to superimpose other structures for achieving same-phase electrical connection on top of the insulating skeleton, thereby reducing the overall size of the stator.

[0019] The first direction is the circumferential direction of the stator core.

[0020] In any of the above technical solutions, further, the terminal accommodating portion includes: an accommodating groove for accommodating the crimped terminal, the accommodating groove is provided with a notch, the notch is located on the side wall of the accommodating groove along the first direction; an overflow glue groove, along the first direction, the overflow glue groove is located on both sides of the accommodating groove, and the overflow glue groove is connected to the notch.

[0021] In this technical solution, the terminal accommodating portion includes an accommodating groove and a glue overflow groove. The accommodating groove is used to accommodate the crimping terminal of the stator, wherein a notch is provided on the accommodating groove. The wire head and wire tail of the same-phase coil extend into the accommodating groove through the notch on one side of the accommodating groove, which plays a role in positioning the coil and ensuring the stability of the coil. At the same time, the electrical connection of the same-phase coil is realized through the crimping terminal.

[0022] In addition, the overflow glue groove is arranged on both sides of the accommodating groove and is connected to the notch. In this way, after the same-phase coils are electrically connected through the wiring terminals, the coils are sealed with sealant at the accommodating groove and the notch, thereby improving the safety performance of the coils. Moreover, due to the setting of the overflow glue groove, in the process of sealing and crimping the terminals with sealant, excess sealant will be blocked by the overflow glue groove, so that the sealant will not overflow to the outside of the terminal accommodating part, thereby achieving better sealing of the coils.

[0023] In a specific application, the receiving groove is provided with two notches, one on each of the two side walls of the receiving groove in the first direction. Similarly, there are two overflow grooves, each corresponding to the two notches, so that when sealing at the two notches, the overflow grooves can prevent the sealant from overflowing at both notches.

[0024] It is understandable that when sealing the crimped terminal and the cut section of the wire, if a low-viscosity sealant is used, the sealant will easily flow along the side walls of the receiving groove, making it difficult to completely seal the crimped terminal and the cut section of the wire. When a high-viscosity sealant is used, due to the low fluidity of the sealant and the relatively narrow notch of the receiving groove, it is difficult to completely cover the crimped terminal and the cut section of the wire. Therefore, the present application can prevent sealant overflow by providing a glue overflow groove, achieving a complete seal between the crimped terminal and the coil wire cut section.

[0025] In any of the above technical solutions, the terminal accommodating portion further includes: an overflowing glue platform, which is arranged on both sides of the accommodating groove along the first direction; and a boss, which is arranged on the overflowing glue platform, at least the boss and the overflowing glue platform enclose an overflowing glue groove.

[0026] In this technical solution, the terminal accommodating portion also includes an overflow glue platform and a boss. The overflow glue platform is arranged on both sides of the accommodating groove, that is, there are protruding overflow glue platforms on both sides of the accommodating groove in the first direction. The boss is arranged on the overflow glue platform, so that at least the overflow glue platform and the boss enclose an overflow glue groove, so that the overflow glue groove surrounds at least a part of the groove opening, and then when pouring sealant into the accommodating groove and the groove opening for sealing, excess sealant can flow into the overflow glue groove to prevent the sealant from overflowing from the terminal accommodating portion.

[0027] It can be understood that the crimping terminals pierce the coils so that the coils of the same phase are connected.

[0028] In a specific application, the crimping terminal is a piercing terminal, so that when the crimping terminal is pressed against the coil in the accommodating slot, it can pierce the insulating film on the surface of the coil, thereby realizing electrical connection of the coils in the same phase for quick connection.

[0029] In any of the above technical solutions, further, the boss includes: a first boss, which is arranged on the side of the accommodating groove away from the wire groove, and the first boss is located on the side of the groove away from the first bracket; a second boss, which is arranged on the side of the accommodating groove close to the wire groove, and the second boss, the second bracket and the accommodating groove enclose an overflow glue groove, and a gap is provided between the second boss and the accommodating groove.

[0030] In this technical solution, the boss includes a first boss and a second boss, which are respectively arranged on the overflowing glue platform on both sides of the receiving groove. The first boss is arranged on the side of the receiving groove away from the wire groove, and is located on the side of the slot away from the first bracket. In this way, when injecting sealant into the receiving groove and the slot, excess sealant will be blocked by the first boss, preventing sealant from overflowing. The second boss is arranged on the side of the receiving groove close to the wire groove, and the second boss, the surface of the second bracket, and the outer wall of the receiving groove together form an overflowing glue groove. The end of the second boss is not completely closed with the wall of the receiving groove, and there is a gap, thereby facilitating the cutting and sealing of the coil wire tail.

[0031] In a specific application, a wiring groove is provided at the bottom of the first boss, and the wiring groove is arranged opposite to the notch, so that the coil can be further fixed in the wiring groove, thereby improving the firmness of the coil.

[0032] In addition, the size of the gap is small to prevent the sealant from flowing out. Specifically, the width of the gap is greater than or equal to 1 mm and less than or equal to 5 mm.

[0033] In any of the above technical solutions, further, the notch includes a first channel and a second channel that are connected, the first channel is located on the top of the second channel, and the side walls of the first channel are gradually expanded toward both sides of the first channel.

[0034] In this technical solution, the slot includes a first channel and a second channel that are connected, that is, the slot is divided into an upper half and a lower half, wherein the first channel is located in the upper half and the second channel is located in the lower half, the upper half and the lower half are connected, and the side wall of the first channel is gradually expanded to facilitate the wire passing through the slot. At the same time, the inclined setting of the upper half of the slot can also facilitate the injection of sealant, so that the sealant can flow along the inclined wall to the bottom part of the slot, thereby improving the sealing effect of the sealant on the coil cross-section.

[0035] In a specific application, the notch is substantially U-shaped, the side wall of the first channel is inclined, and the side wall of the second channel is substantially straight.

[0036] In any of the above technical solutions, further, the width of the wire trough is greater than the width of the slot opening.

[0037] In this technical solution, the wire head and tail of the coil are both arranged in the slot, which facilitates the entry of the coil into the slot. The width of the wire slot is larger than the width of the slot, so that the wire head and tail are more tightly connected to the slot when entering the slot, thereby improving the fixation of the slot to the coil.

[0038] In a specific application, the width of the wire trough is the width of the wire trough along the first direction, and the width of the slot is the width of the slot along the second direction. Specifically, the wire trough and the slot are both roughly U-shaped, and the width of the wire trough and the width of the slot are the distance between the left and right side walls of the U-shape.

[0039] By setting the slot and the wire slot width, the slot can accommodate both the wire head and the wire tail of the coil at the same time, and can also improve the tightness of the coil.

[0040] In any of the above technical solutions, further, the insulating frame also includes: a protrusion, which is provided on a side of the second bracket away from the first bracket, and along the first direction, the protrusion is located on the second side of the wire groove.

[0041] In this technical solution, the insulating skeleton also includes a protrusion, which is arranged on the second bracket and is located on the side of the second bracket away from the first bracket and the third bracket. The protrusion, the wire groove and the terminal accommodating portion are arranged in sequence along the first direction. The setting of the protrusion can limit the coil of the coil to prevent the coil from falling out. Specifically, the setting of the protrusion can prevent the wire tail of the coil from falling out, thereby improving the fixation of the coil.

[0042] Specifically, for the segmented iron core, each segmented iron core is wound with a coil, and each coil includes a wire head and a wire tail. After winding, the wire tail extends from the bottom of the protrusion into the wire slot, and the coil is limited by the wire slot.

[0043] It can be understood that along the first direction, the wire groove includes a first side and a second side, and the first side of the wire groove and the second side of the wire groove are two sides of the wire groove that are relatively arranged, wherein the side of the wire groove close to the terminal accommodating portion is the first side of the wire groove, and the side of the wire groove close to the protruding portion is the second side of the wire groove.

[0044] In any of the above technical solutions, further, at least a portion of the top wall of the protrusion is inclined toward the bottom of the second bracket.

[0045] In this technical solution, at least a portion of the top wall of the protrusion is inclined toward the bottom of the second bracket. On the one hand, this reduces the material used for the protrusion and reduces production costs. On the other hand, when the insulating frame is used in conjunction with other structures, it avoids interference with other structures.

[0046] In a specific application, the cross section of the raised portion is approximately triangular.

[0047] In specific applications, the motor includes a stator core, an insulation frame, and an insulation cover. The insulation frame is positioned at both ends of the stator core, and the insulation cover is positioned at both ends of the insulation frame away from the stator core. The insulation cover provides insulation and improves the safety of the motor. The raised portion engages with the insulation cover, connecting the insulation frame and insulation cover, improving the reliability of the connection between the insulation cover and insulation frame.

[0048] It can be understood that the insulating cover plate and the insulating frame are both made of insulating materials.

[0049] In any of the above technical solutions, further, the protrusion is close to the surface of the bottom of the second bracket and is located on a side of the bottom wall of the wire trough away from the bottom of the second bracket.

[0050] In this technical solution, the surface of the raised portion close to the bottom of the second bracket is located on the side of the bottom wall of the wire groove away from the bottom of the second bracket. Through the above arrangement, the surface of the raised portion close to the bottom of the second bracket is higher than the bottom wall of the wire groove, that is, the bottom wall of the wire groove is lower than the lower surface of the raised portion, and then the tail of the coil is wound around the wire groove from the side of the raised portion away from the wire groove, which can avoid the coil from bending at the wire groove, thereby making the routing of the coil tighter.

[0051] Specifically, the distance difference between the lower surface of the protrusion and the bottom wall of the wire slot is greater than or equal to the diameter of the wire in the coil. It can be understood that a wire is wound around the segmented iron core and the insulating frame to form a coil.

[0052] In any of the above technical solutions, further, a length of the terminal accommodating portion protruding from the second bracket is greater than a length of the protruding portion protruding from the second bracket.

[0053] In this technical solution, both the terminal accommodating portion and the protruding portion protrude from the second bracket toward the side away from the first bracket, wherein the length of the protruding portion protruding from the second bracket is shorter than the length of the terminal accommodating portion protruding from the second bracket. In this way, when the insulating frame and the insulating cover are connected, interference with the connection between the two is avoided, thereby ensuring the reliability of the connection between the two.

[0054] It can be understood that the second bracket, the third bracket and the first bracket are distributed in sequence along the second direction, and the length of the protrusion along the second direction is smaller than the length of the terminal accommodating portion.

[0055] It can be understood that the second direction is the radial direction of the stator core.

[0056] In any of the above technical solutions, further, the insulating frame also includes: a step portion, which is provided on the second bracket, and the step portion is located on a side of the protrusion away from the wire groove.

[0057] In this technical solution, the insulating frame further includes a step portion, which is provided on the second bracket and is used to support the coil, specifically, the step portion is used to support the wire tail of the coil, thereby improving the tightness of the coil winding.

[0058] Specifically, the step portion is arranged on the side of the protrusion away from the wire slot, so that the wire tail portion of the coil is wound from the upper surface of the step portion to the bottom of the protrusion, and then extends into the wire slot, and the wire tail portion of the coil is fixed by the wire slot.

[0059] In any of the above technical solutions, further, the third bracket is provided with multiple auxiliary grooves, any auxiliary groove extends along the first direction, multiple auxiliary grooves are distributed along the second direction, and the first bracket, the third bracket and the second bracket are distributed in sequence along the second direction.

[0060] In this technical solution, the third bracket is provided with multiple auxiliary slots, which secure the coil, improving the tightness and stability of the coil winding. Each auxiliary slot extends along a first direction, and multiple auxiliary slots are arranged in an array along a second direction. The coil is wound around the insulating frame through the auxiliary slots.

[0061] Specifically, the auxiliary groove is provided on the upper surface of the third bracket, and when the auxiliary groove naturally extends along the outer surface of the third bracket, it is directly cut by the side surface of the third bracket.

[0062] In any of the above technical solutions, further, the inclined portion is close to the edge of the bottom of the second bracket and is substantially flush with the bottom of the auxiliary groove.

[0063] In this technical solution, the inclined portion is close to the edge of the bottom of the second bracket and is roughly aligned with the bottom of the auxiliary slot, which avoids bending of the coil and ensures the tightness of the coil winding.

[0064] It is understood that the edge of the inclined portion close to the bottom of the second bracket, i.e., the lower edge of the inclined portion, is substantially flush with the bottom of the auxiliary groove, i.e., the lower edge of the inclined portion is flush with the bottom of the auxiliary groove, or the lower edge of the inclined portion is slightly higher than the bottom of the auxiliary groove.

[0065] In any of the above technical solutions, further, a wall surface of the wire trough close to the terminal accommodating portion is substantially flush with a wall surface of the third bracket close to the wire trough.

[0066] In this technical solution, the wall of the wire slot close to the terminal accommodating portion is roughly flush with the wall of the third bracket close to the wire slot. In this way, when the coil is wound from the wire slot to the third bracket, the coil can be wound more tightly, thereby improving the slot fill rate of the stator core.

[0067] It can be understood that the wall of the wire trough close to the terminal accommodating portion is roughly flush with the wall of the third bracket close to the wire trough, that is, the wall of the wire trough close to the accommodating portion is flush with the wall of the third bracket close to the wire trough, or there is a small gap between the wall of the wire trough close to the accommodating portion and the wall of the third bracket close to the wire trough.

[0068] In any of the above technical solutions, further, a cutout is provided on a side of the first bracket facing the second bracket, the cutout is provided close to the bottom of the first bracket, and along the first direction, the cutout is located on both sides of the third bracket.

[0069] In this technical solution, a cutout is provided on the first bracket, and the cutout is located on the inner side of the first bracket, which can avoid the winding of the coil and ensure the tightness of the coil winding.

[0070] Specifically, the incision is located on the side of the first bracket facing the second bracket and is arranged close to the bottom of the first bracket. Furthermore, along the first direction, the incision is arranged on both sides of the third bracket, thereby reducing the overall weight of the insulating frame and reducing production costs, and avoiding excessive squeezing of the coil by the third bracket and affecting the winding of the coil.

[0071] In practice, the wall of the first bracket facing the second bracket is approximately flat, while the wall of the first bracket facing away from the second bracket is arc-shaped. Consequently, when the insulating frame is applied to the stator, the first bracket forms a circular shape that conforms to the shape of the stator teeth, facilitating the installation and movement of the rotor. Furthermore, the cutouts allow the shape of the first bracket to align with the end of the stator teeth facing the interior of the stator, increasing the stator's slot fill ratio and ensuring a tighter overall connection.

[0072] Specifically, the cutout is a flat but non-through structure.

[0073] In any of the above technical solutions, further, a side of the cutout close to the top of the first bracket is flush with the top of the auxiliary groove.

[0074] In this technical solution, one side of the cutout close to the top of the first bracket is flush with one side of the top of the auxiliary slot, thereby ensuring the avoidance effect of the cutout on the coil and increasing the slot fill rate of the stator.

[0075] In any of the above technical solutions, further, the insulating frame also includes: a mark, which is provided on at least one of the second bracket and the first bracket, and the mark corresponds to the width of the slot of the terminal accommodating portion and the width of the auxiliary slot of the third bracket.

[0076] In this technical solution, the insulating skeleton also includes a mark, which is set on at least one of the second bracket and the first bracket. It can be understood that when winding different stators, different coil diameters will correspond, and then different auxiliary slot widths and different slot widths will correspond. That is, the diameter of the coil is one-to-one corresponding to the width of the slot and the width of the auxiliary slot. Therefore, the diameter of the coil changes synchronously with the width of the slot and the width of the auxiliary slot. Therefore, the technical solution proposed in this application sets a mark on the insulating skeleton, and the mark corresponds one-to-one to the diameter of the coil, the width of the slot and the width of the auxiliary slot. In this way, different insulating skeletons can be selected according to the marks according to different coil diameters. Specifically, different insulating skeletons correspond to slot widths and auxiliary slot widths of different sizes, so that insulating skeletons of various sizes can adapt to coils of different sizes.

[0077] Specifically, the width of the slot and the yoke width of the auxiliary slot have various sizes, which can be selected and used according to actual conditions.

[0078] Specifically, the mark may be a number, a letter or a symbol with equivalent function.

[0079] In a specific application, the mark is set on the terminal accommodating portion of the second bracket, and further the mark is set on the top of the terminal accommodating portion for easy identification by the user.

[0080] According to a second aspect of the present invention, a stator is further proposed, comprising: a stator core, the stator core comprising a plurality of segmented cores connected in sequence, the segmented cores comprising teeth, the teeth of two adjacent segmented cores enclosing a stator slot; and an insulating frame as proposed in any one of the first aspects, the number of insulating frames being multiple, insulating frames being provided at both ends of any segmented core, and a third bracket being arranged opposite to the teeth; and a winding, the winding being wound on the teeth and the insulating frame.

[0081] The stator provided in the second aspect of the present invention includes the insulating frame proposed in any technical solution of the first aspect, and therefore has all the beneficial effects of the insulating frame.

[0082] Furthermore, the stator includes a stator core, which comprises a plurality of sequentially connected segmented cores. The segmented cores include teeth, and the teeth of two adjacent segmented cores define stator slots for accommodating windings. Each segmented core is provided with an insulating frame at both ends, allowing the windings to be wound around the teeth and the insulating frame, ensuring insulation performance. This winding method also allows for electrical connection of the same-phase windings on the insulating frame, eliminating the need for additional structures for electrical connection. This reduces the axial height of the stator and makes the stator ends more compact.

[0083] In the above technical solution, further, the winding includes multiple coils, a coil is wound on a segmented iron core and an insulating frame at both ends of the segmented iron core, the coil includes a wire head and a wire tail, and the wire slot is used to accommodate the wire head and the wire tail.

[0084] In this technical solution, the winding includes multiple coils, and a segmented iron core and the insulating frames at both ends of the core core constitute an iron core assembly, wherein each iron core assembly is wound with a coil. After each coil is wound, the multiple iron core assemblies are combined into a circle to form a stator, thereby improving the slot fill rate while avoiding scratching the insulation layer on the coil surface.

[0085] The coil includes a wire head and a wire tail, and the wire groove is used to accommodate the wire head and the wire tail to ensure the tightness of the coil winding.

[0086] Specifically, the wire head is clamped in the wire slot at one end of the stator core in the axial direction, then extends toward the other end of the stator core and begins winding from the side of the insulating frame away from the wire slot, so that the wire tail is located on the side of the insulating frame close to the wire slot. The wire tail is then wound to the step, passes through the upper surface of the step, extends below the raised portion, and then extends into the wire slot, where it is pre-fixed. After all the coils are wound, the multiple segmented cores are combined into a circle to form the stator. Compared to the existing technology, the technical solution proposed in this application not only improves the stator slot fill rate, but also avoids damage to the insulation layer of the coil itself.

[0087] In the above technical solution, the stator further includes: an insulating cover plate, which is arranged on a side of the insulating frame away from the stator core, and the insulating cover plate is engaged with a raised portion of the insulating frame.

[0088] In this technical solution, the insulation frame also includes an insulation cover plate, which is located on the side of the insulation frame away from the stator core. This insulation frame protects the coil ends from curling, improving the safety of the stator. The insulation cover plate is connected to the raised portion of the insulation frame, securing the insulation cover plate, making the overall stator structure more compact and effectively locking the two together.

[0089] Furthermore, the insulating cover plate is snap-fitted to the raised portion of the insulating frame.

[0090] In a specific application, a buckle is provided on the insulating cover, and the buckle is engaged with the protrusion. It can be understood that the length of the protrusion is shorter than the length of the terminal accommodating portion, so the engagement between the buckle and the protrusion is guaranteed.

[0091] Furthermore, any segmented iron core includes a plurality of punching sheets, and the plurality of punching sheets are stacked and distributed along the axial direction of the stator iron core.

[0092] In this technical solution, each segmented iron core is provided with a plurality of punching sheets, and the plurality of punching sheets are stacked and distributed along the axial direction of the stator iron core, so that overlapping portions are formed at the peripheral edges of the punching sheets. When the plurality of punching sheets are stacked and distributed along the axial direction of the iron core, overlapping gaps are defined between adjacent punching sheets and are formed in stator slots, so as to facilitate winding of the winding on the teeth of the stator iron core and being located in the stator slots.

[0093] Specifically, the punching sheets are silicon steel sheets.

[0094] Furthermore, two adjacent segmented iron cores are rotatably connected via the overlapping portion.

[0095] In this technical solution, two adjacent segmented iron cores are rotatably connected via the overlapping portion, that is, the two segmented iron cores can rotate relative to each other after being connected.

[0096] By rotating and connecting two adjacent segmented iron cores through the overlapping part, one segmented iron core can be rotated around the other segmented iron core with the connection point of the overlapping part as the center of the circle. This connection method is simple and reliable, and it is convenient for the operator to adjust the shape and structure of the stator iron core. The position of the segmented iron core can be adjusted according to usage requirements.

[0097] In the above technical solution, further, the stator core includes a tooth portion and a yoke portion, and the stator core has at least a first state and a second state; in the first state, a plurality of segmented cores are combined to form a first ring shape, and the tooth portion is located on the inner side of the yoke portion; in the second state, a plurality of segmented cores are unfolded to form a roughly straight line.

[0098] In this technical solution, the stator core has a first state, which is the normal state after the stator core is wound with windings. In this first state, the multiple segmented cores are combined to form a first ring shape, with the teeth located inside the yoke. In this state, the windings are wound into the stator slots formed by adjacent teeth, with the windings close to the inside of the stator core. The two adjacent stator cores are rotatably connected by an overlapping portion provided on the outer yoke, together enclosing a circular stator core.

[0099] The stator core also has a second state. Because two adjacent segmented cores are rotatably connected, when the segments move relative to each other, the multiple segments unfold to form a roughly straight line. In this unfolded state, the teeth of each segmented core are arranged roughly in a straight line. In this unfolded state, the space between the stator slots is larger than in the first state, making winding easier.

[0100] By placing the stator core in the second state, the teeth can be arranged in a roughly straight line, 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 closed back to the first state, so that the individual core segments are combined to form a circular stator core, ensuring a stable and reliable stator core structure.

[0101] Furthermore, in the second state, the two segmented iron cores at both ends are connected together after being joined into a circle. Specifically, the two segmented iron cores can be welded after being joined into a circle.

[0102] It can be understood that, in the second state, the stator core is substantially in a straight line, including that the stator core is in a straight line, or that the stator core has a certain curvature.

[0103] In the above technical solution, further, the multiple punching sheets include a first punching sheet layer and a second punching sheet layer that are alternately arranged; an overlapping portion is provided on the first side of the first punching sheet layer, the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer, and the two adjacent first punching sheet layers enclose an overlapping gap; an overlapping portion is provided on the second side of the second punching sheet layer, the overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer, and the two adjacent second punching sheet layers enclose an overlapping gap; in two adjacent segmented iron cores, the overlapping portion of one segmented iron core is inserted into the overlapping gap of the other segmented iron core.

[0104] In this technical solution, the plurality of punching sheets include a first punching sheet layer and a second punching sheet layer, and the plurality of first punching sheets and the plurality of second punching sheets are alternately distributed along the axial direction of the stator core. The first punching sheet layer is provided with an overlapping portion on the first side, and the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent first punching sheet layers both protrude from the second punching sheet layer arranged between the two adjacent first punching sheet layers, so that an overlapping gap is enclosed between the two adjacent first punching sheet layers. The second punching sheet layer is provided with an overlapping portion on the second side, that is, the second punching sheet layer is provided with an overlapping portion on a side different from the first punching sheet layer. The overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent second punching sheet layers both protrude from the first punching sheet layer arranged between the two adjacent second punching sheet layers, so that an overlapping gap can also be enclosed between the two adjacent second punching sheet layers.

[0105] It is understood that when the plurality of first punching sheet layers and the plurality of second punching sheet layers are alternately distributed along the circumference of the stator core, the overlapping portions of the plurality of first punching sheet layers on the first side are staggered with the overlapping portions of the plurality of second punching sheet layers on the second side. Furthermore, the overlapping gaps between two adjacent first punching sheet layers and the overlapping gaps between two adjacent second punching sheet layers are respectively located on opposite sides of the segmented core and are staggered.

[0106] An overlapping portion and an overlapping gap are respectively provided on the side adjacent to each other of two adjacent segmented iron cores. Since the overlapping portions of multiple first punching sheet layers arranged on the first side are staggered with the overlapping portions of multiple second punching sheet layers arranged on the second side, and the overlapping gaps between two adjacent first punching sheet layers are staggered with the overlapping gaps between two adjacent second punching sheet layers, the overlapping portion of one segmented iron core is inserted into the overlapping gap of another segmented iron core, thereby realizing the connection between the two adjacent segmented iron cores.

[0107] By alternating the first and second punching sheet layers, providing overlapping portions on different sides of the first and second punching sheet layers, and enclosing overlapping gaps on different sides of the first and second punching sheet layers, two adjacent segmented cores can be connected through the overlapping portions and overlapping gaps. Specifically, the overlapping portion of one segmented core is inserted into the overlapping gap of another segmented core. This connection method is stable and reliable, and the operator can quickly disassemble and assemble the stator core, improving work efficiency. In addition, multiple segmented cores can be connected to each other using the same structure, which reduces the types of segmented cores, improves the versatility of the segmented cores, and reduces product costs.

[0108] In the above technical solution, further, the multiple punching sheets include a first punching sheet layer and a second punching sheet layer that are alternately arranged; an overlapping portion is provided on the first side of the first punching sheet layer, the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer, and the two adjacent first punching sheet layers enclose an overlapping gap; an overlapping portion is provided on the second side of the second punching sheet layer, the overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer, and the two adjacent second punching sheet layers enclose an overlapping gap; in two adjacent segmented iron cores, the overlapping portion of one segmented iron core is inserted into the overlapping gap of the other segmented iron core.

[0109] In this technical solution, the plurality of punching sheets include a first punching sheet layer and a second punching sheet layer, and the plurality of first punching sheets and the plurality of second punching sheets are alternately distributed along the axial direction of the stator core. The first punching sheet layer is provided with an overlapping portion on the first side, and the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent first punching sheet layers both protrude from the second punching sheet layer arranged between the two adjacent first punching sheet layers, so that an overlapping gap is enclosed between the two adjacent first punching sheet layers. The second punching sheet layer is provided with an overlapping portion on the second side, that is, the second punching sheet layer is provided with an overlapping portion on a side different from the first punching sheet layer. The overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent second punching sheet layers both protrude from the first punching sheet layer arranged between the two adjacent second punching sheet layers, so that an overlapping gap can also be enclosed between the two adjacent second punching sheet layers.

[0110] It is understood that when the plurality of first punching sheet layers and the plurality of second punching sheet layers are alternately distributed along the circumference of the stator core, the overlapping portions of the plurality of first punching sheet layers on the first side are staggered with the overlapping portions of the plurality of second punching sheet layers on the second side. Furthermore, the overlapping gaps between two adjacent first punching sheet layers and the overlapping gaps between two adjacent second punching sheet layers are respectively located on opposite sides of the segmented core and are staggered.

[0111] An overlapping portion and an overlapping gap are respectively provided on the side adjacent to each other of two adjacent segmented iron cores. Since the overlapping portions of multiple first punching sheet layers arranged on the first side are staggered with the overlapping portions of multiple second punching sheet layers arranged on the second side, and the overlapping gaps between two adjacent first punching sheet layers are staggered with the overlapping gaps between two adjacent second punching sheet layers, the overlapping portion of one segmented iron core is inserted into the overlapping gap of another segmented iron core, thereby realizing the connection between the two adjacent segmented iron cores.

[0112] By alternating the first and second punching sheet layers, providing overlapping portions on different sides of the first and second punching sheet layers, and enclosing overlapping gaps on different sides of the first and second punching sheet layers, two adjacent segmented cores can be connected through the overlapping portions and overlapping gaps. Specifically, the overlapping portion of one segmented core is inserted into the overlapping gap of another segmented core. This connection method is stable and reliable, and the operator can quickly disassemble and assemble the stator core, improving work efficiency. In addition, multiple segmented cores can be connected to each other using the same structure, which reduces the types of segmented cores, improves the versatility of the segmented cores, and reduces product costs.

DETAILED DESCRIPTION

[0136] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0137] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0138] Refer to the following Figures 1 to 12 An insulation skeleton, a stator, a motor, a compressor, and a vehicle according to some embodiments of the present invention are described.

[0139] Example 1:

[0140] like Figure 1 and Figure 2 As shown, according to an embodiment of the first aspect of the present invention, the present invention provides an insulating frame. The insulating frame includes: a first bracket 1, a second bracket 2 and a third bracket 3.

[0141] Specifically, the second bracket 2 is arranged opposite to the first bracket 1, and a wire groove 20 is provided on the second bracket 2. The wire groove 20 passes through the wall of the second bracket 2, and a part of the bottom wall of the wire groove 20 is inclined toward the bottom of the second bracket 2 to form an inclined portion 22. The inclined portion 22 is located on the side of the wire groove 20 facing the first bracket 1; the third bracket 3 is arranged between the first bracket 1 and the second bracket 2 and is connected to the first bracket 1 and the second bracket 2.

[0142] The insulating frame provided by the present invention includes a first bracket 1, a second bracket 2, and a third bracket 3. The second bracket 2 and the first bracket 1 are arranged in a relative manner. The third bracket 3 is arranged between the first bracket 1 and the second bracket 2, and one end of the third bracket 3 is connected to the first bracket 1, and the other end of the third bracket 3 is connected to the second bracket 2, so that the first bracket 1, the second bracket 2, and the third bracket 3 are connected as a whole. Among them, the second bracket 2 is provided with a wire groove 20, and the wire groove 20 includes a bottom wall. The bottom wall of the wire groove 20 is inclined toward the bottom of the second bracket 2 to form an inclined portion 22. The inclined portion 22 is located on the side close to the first bracket 1. In this way, when winding the wire through the insulating frame, the coil extends into the wire groove 20 from the side of the wire groove 20 away from the first bracket 1, and then extends along the inclined portion 22 toward the bottom of the first bracket 1, thereby facilitating the winding of the coil. At the same time, the wire groove 20 can pre-fix the coil, making the winding of the coil more compact, improving the fixity of the coil, and improving the slot fill rate of the stator core 4.

[0143] In specific applications, the insulating frame is used in a stator, which includes a stator core 4, a coil, and the insulating frame. The insulating frame is arranged at both ends of the stator core 4 in the axial direction, and the coil is wound around the insulating frame and the stator core 4. The first bracket 1, the second bracket 2, and the third bracket 3 together enclose a winding accommodating portion for accommodating the coil. The stator core 4 feeds the wires through the wire slots 20, causing the coils to tilt downward along the inclined portion 22, allowing the coils to be wound more tightly.

[0144] Specifically, the first bracket 1 , the second bracket 2 and the third bracket 3 are integrally formed.

[0145] It is understood that the wire trough 20 includes an opening and a bottom wall disposed opposite the opening. A portion of the bottom wall of the wire trough 20 is tilted toward the bottom of the second bracket 2 to form an inclined portion 22. Furthermore, the inclined portion 22 is disposed on the side of the wire trough 20 facing the first bracket 1, that is, the inclined portion 22 is disposed on the inner side of the first bracket 1. In other words, the upper portion of the wire trough 20 is generally U-shaped, with the opening located at the top of the U-shape, and the lower portion of the wire trough 20 is sloped, thereby making the coil more compact when passing the wire and improving the stability of the coil winding.

[0146] Specifically, when the insulating frame is applied to the stator, the first bracket 1 is close to the inner side of the stator core 4, the second bracket 2 is close to the outer side of the stator core 4, and the third bracket 3 is connected to the first bracket 1 and the second bracket 2 and is located therebetween.

[0147] Example 2:

[0148] like Figure 3 and Figure 4As shown, according to one embodiment of the present invention, on the basis of the above embodiment, further: the insulating skeleton also includes: a terminal accommodating portion 24, the terminal accommodating portion 24 is arranged on the side of the second bracket 2 away from the first bracket 1, for accommodating the crimping terminal, along the first direction, the terminal accommodating portion 24 is located on the first side of the wire groove 20.

[0149] In this embodiment, the insulating skeleton also includes a terminal accommodating portion 24, which is arranged on the second bracket 2, and the crimping terminal is arranged in the terminal accommodating portion 24. The coils of the same phase are connected in the terminal accommodating portion 24 through the crimping terminal, so that the coils of the same phase are connected in series. Among them, the terminal accommodating portion 24 is arranged on the side of the second bracket 2 away from the first bracket 1, thereby avoiding occupying the coil winding space. At the same time, the terminal accommodating portion 24 and the wire slot 20 are distributed along the first direction, which facilitates the winding of the coil and the series connection of the same-phase coils. In addition, by arranging the terminal accommodating slot 240 on the insulating skeleton, it is avoided to superimpose other structures for achieving same-phase electrical connection on top of the insulating skeleton, thereby reducing the overall size of the stator.

[0150] The first direction is the circumferential direction of the stator core 4 .

[0151] Example 3:

[0152] like Figure 1 and Figure 3 As shown, according to an embodiment of the present invention, on the basis of the above embodiment, further: the terminal accommodating portion 24 includes: an accommodating groove 240, for accommodating the crimping terminal, the accommodating groove 240 is provided with a notch 2400, and the notch 2400 is located on the side wall of the accommodating groove 240 along the first direction; an overflow glue groove 242, along the first direction, the overflow glue groove 242 is located on both sides of the accommodating groove 240, and the overflow glue groove 242 is connected to the notch 2400.

[0153] In this embodiment, the terminal accommodating portion 24 includes an accommodating groove 240 and a glue overflow groove 242. The accommodating groove 240 is used to accommodate the crimping terminal of the stator, wherein a notch 2400 is provided on the accommodating groove 240. The wire head and wire tail of the same-phase coil extend into the accommodating groove 240 through the notch 2400 on one side of the accommodating groove 240, which plays a role in positioning the coil, ensuring the stability of the coil, and at the same time realizing the electrical connection of the same-phase coil through the crimping terminal.

[0154] In addition, the overflow glue groove 242 is arranged on both sides of the accommodating groove 240 and is connected to the notch 2400. In this way, after the same-phase coil is electrically connected through the wiring terminal, the coil is sealed with sealant at the accommodating groove 240 and the notch 2400 to improve the safety performance of the coil. Moreover, due to the setting of the overflow glue groove 242, in the process of sealing the crimped terminal with sealant, excess sealant will be blocked by the overflow glue groove 242, so that the sealant will not overflow to the outside of the terminal accommodating portion 24, thereby achieving better sealing of the coil.

[0155] In a specific application, the receiving groove 240 is provided with two notches 2400, which are respectively provided on two side walls of the receiving groove 240 in the first direction. Similarly, there are two overflow glue grooves 242, which are respectively provided corresponding to the two notches 2400. When sealing at the two notches 2400, the overflow glue grooves 242 can prevent the sealant from overflowing at both notches 2400.

[0156] It is understandable that when sealing the crimped terminal and the cut section of the wire, if a low-viscosity sealant is used, the sealant will easily flow along the sidewalls of the receiving groove 240, making it difficult to completely seal the crimped terminal and the cut section of the wire. When a high-viscosity sealant is used, due to the low fluidity of the sealant and the relatively narrow notch 2400 of the receiving groove 240, it is difficult to completely cover the crimped terminal and the cut section of the wire. Therefore, the present application provides a glue overflow groove 242 to prevent sealant overflow and achieve complete sealing of the crimped terminal and the coil wire cut section.

[0157] Example 4:

[0158] like Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, on the basis of the above embodiment, further: the terminal accommodating portion 24 also includes: an overflow glue platform 244, along the first direction, the overflow glue platform 244 is arranged on both sides of the accommodating groove 240; a boss 246, provided on the overflow glue platform 244, at least the boss 246 and the overflow glue platform 244 together enclose the overflow glue groove 242.

[0159] In this embodiment, the terminal accommodating portion 24 also includes an overflow glue platform 244 and a boss 246. The overflow glue platform 244 is arranged on both sides of the accommodating groove 240, that is, there are protruding overflow glue platforms 244 on both sides of the accommodating groove 240 in the first direction, and the boss 246 is arranged on the overflow glue platform 244, so that at least the overflow glue platform 244 and the boss 246 enclose an overflow glue groove 242, so that the overflow glue groove 242 surrounds at least a portion of the notch 2400, and then when pouring sealant into the accommodating groove 240 and the notch 2400 for sealing, excess sealant can flow into the overflow glue groove 242 to prevent the sealant from overflowing from the terminal accommodating portion 24.

[0160] It can be understood that the crimping terminals pierce the coils so that the coils of the same phase are connected.

[0161] In a specific application, the crimping terminal is a piercing terminal, so that when the crimping terminal is pressed toward the coil in the accommodating groove 240, it can pierce the insulating film on the surface of the coil, thereby achieving electrical connection of the same-phase coils for quick connection.

[0162] Furthermore, if Figure 2 As shown, the boss 246 includes: a first boss 2460, which is arranged on the side of the accommodating groove 240 away from the wire groove 20, and the first boss 2460 is located on the side of the slot 2400 away from the first bracket 1; a second boss 2462, which is arranged on the side of the accommodating groove 240 close to the wire groove 20, and the second boss 2462 and the second bracket 2 and the accommodating groove 240 enclose the overflow glue groove 242, and a gap is provided between the second boss 2462 and the accommodating groove 240.

[0163] 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 arranged on the overflow platform 244 on both sides of the accommodating groove 240, wherein the first boss 2460 is arranged on the side of the accommodating groove 240 away from the wire groove 20, and is located on the side of the slot 2400 away from the first bracket 1. In this way, when injecting sealant into the accommodating groove 240 and the slot 2400, excess sealant will be blocked by the first boss 2460, thereby preventing the sealant from overflowing.

[0164] The second boss 2462 is arranged on the side of the accommodating groove 240 close to the wire groove 20, and the second boss 2462 and the surface of the second bracket 2 and the outer wall of the accommodating groove 240 enclose an overflow glue groove 242, wherein the end of the second boss 2462 and the wall of the accommodating groove 240 are not completely closed and have a gap, thereby facilitating the cutting and sealing of the wire tail of the coil.

[0165] In a specific application, a wiring groove 20 is provided at the bottom of the first boss 2460 , and the wiring groove 20 is arranged opposite to the notch 2400 , so that the coil can be further fixed in the wiring groove 20 , thereby improving the firmness of the coil.

[0166] In addition, the size of the gap is small to prevent the sealant from flowing out. Specifically, the width of the gap is greater than or equal to 1 mm and less than or equal to 5 mm.

[0167] Embodiment 5:

[0168] like Figure 5As shown, according to an embodiment of the present invention, on the basis of the above embodiment, further: the slot 2400 includes a first channel 2402 and a second channel 2404 connected to each other, the first channel 2402 is located at the top of the second channel 2404, and the side walls of the first channel 2402 are gradually expanded toward both sides of the first channel 2402.

[0169] In this embodiment, the slot 2400 includes a first channel 2402 and a second channel 2404 that are connected, that is, the slot 2400 is divided into an upper half and a lower half, wherein the first channel 2402 is located in the upper half and the second channel 2404 is located in the lower half, the upper half and the lower half are connected, and the side wall of the first channel 2402 is gradually expanded, so that the slot 2400 is convenient for passing the wire. At the same time, the inclined setting of the upper half of the slot 2400 can also facilitate the injection of sealant, so that the sealant can flow along the inclined wall to the bottom part of the slot 2400, thereby improving the sealing effect of the sealant on the coil cross-section.

[0170] In a specific application, the notch 2400 is substantially U-shaped, the sidewall of the first channel 2402 is inclined, and the sidewall of the second channel 2404 is substantially straight.

[0171] Example 6:

[0172] According to an embodiment of the present invention, based on the above embodiment, further: the width of the wire trough 20 is greater than the width of the notch 2400 .

[0173] In this embodiment, the wire head and wire tail of the coil are both arranged in the slot 2400 to facilitate the entry of the coil into the slot. The width of the wire slot 20 is larger than the width of the slot 2400, so that the wire head and wire tail are more tightly connected to the slot 2400 when entering the slot 2400, thereby improving the fixation of the slot 2400 to the coil.

[0174] In a specific application, the width of the wire trough 20 is the width of the wire trough 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 trough 20 and the notch 2400 are both roughly U-shaped, and the width of the wire trough 20 and the width of the notch 2400 are the distance between the left and right side walls of the U-shape.

[0175] By setting the width of the slot 2400 and the wire slot 20, the slot 2400 can accommodate the wire head and wire tail of the coil at the same time, and can also improve the tightness of the coil.

[0176] Example 6:

[0177] like Figure 6 、 Figure 7 and Figure 9As shown, according to an embodiment of the present invention, based on the above embodiment, further: the insulating frame also includes: a protrusion 26, which is provided on the side of the second bracket 2 away from the first bracket 1, and along the first direction, the protrusion 26 is located on the second side of the wire groove 20.

[0178] In this embodiment, the insulating skeleton also includes a protrusion 26, which is arranged on the second bracket 2 and is located on the side of the second bracket 2 away from the first bracket 1 and the third bracket 3. The protrusion 26, the wire groove 20 and the terminal accommodating portion 24 are arranged in sequence along the first direction. The setting of the protrusion 26 can limit the coil of the coil and prevent the coil from falling out. Specifically, the setting of the protrusion 26 can prevent the wire tail of the coil from falling out, thereby improving the fixity of the coil.

[0179] Specifically, for the segmented iron core, each segmented iron core is wound with a coil, and each coil includes a wire head and a wire tail. After winding, the wire tail extends from the bottom of the protrusion 26 into the wire slot 20, and the coil is limited by the wire slot 20.

[0180] It can be understood that along the first direction, the wire groove 20 includes a first side and a second side, and the first side of the wire groove 20 and the second side of the wire groove 20 are two sides of the wire groove 20 that are relatively arranged, wherein the side of the wire groove 20 close to the terminal accommodating portion 24 is the first side of the wire groove 20, and the side of the wire groove 20 close to the protrusion 26 is the second side of the wire groove 20.

[0181] Embodiment seven:

[0182] like Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, on the basis of the above embodiment, further: at least a portion of the top wall of the protrusion 26 is inclined toward the bottom of the second bracket 2.

[0183] In this embodiment, at least a portion of the top wall of the protrusion 26 is inclined toward the bottom of the second bracket 2. On the one hand, this reduces the material used for the protrusion 26 and reduces production costs. On the other hand, when the insulating frame is used in conjunction with other structures, it avoids interference with other structures.

[0184] In a specific application, the cross section of the raised portion 26 is substantially triangular.

[0185] In a specific application, the motor includes a stator core 4, an insulating frame, and an insulating cover plate 6. The insulating frame is disposed at both ends of the stator core 4, and the insulating cover plates 6 are disposed at both ends of the insulating frame away from the stator core 4. The insulating cover plates 6 provide insulation and enhance the safety of the motor. The raised portions 26 engage the insulating cover plates 6, connecting the insulating frame and the insulating cover plates 6 and improving the reliability of the connection between the insulating cover plates 6 and the insulating frame.

[0186] It can be understood that the insulating cover plate 6 and the insulating frame are both made of insulating materials.

[0187] Furthermore, the protrusion 26 is close to the surface of the bottom of the second bracket 2 and is located on a side of the bottom wall of the wire trough 20 away from the bottom of the second bracket 2 .

[0188] In this embodiment, the raised portion 26 is close to the surface of the bottom of the second bracket 2 and is located on the side of the bottom wall of the wire groove 20 away from the bottom of the second bracket 2. Through the above arrangement, the raised portion 26 is close to the surface of the bottom of the second bracket 2 and is higher than the bottom wall of the wire groove 20, that is, the bottom wall of the wire groove 20 is lower than the lower surface of the raised portion 26, and then the tail of the coil is wound around the wire groove 20 from the side of the raised portion 26 away from the wire groove 20, which can avoid the coil from bending at the wire groove 20, thereby making the routing of the coil tighter.

[0189] Specifically, the distance difference between the lower surface of the protrusion 26 and the bottom wall of the wire slot 20 is greater than or equal to the diameter of the wire in the coil. It can be understood that a wire is wound around the segmented iron core and the insulating frame to form a coil.

[0190] Furthermore, the length of the terminal accommodating portion 24 protruding from the second bracket 2 is greater than the length of the protruding portion 26 protruding from the second bracket 2 .

[0191] In this embodiment, the terminal accommodating portion 24 and the protruding portion both protrude from the second bracket 2 toward the side away from the first bracket 1, wherein the length of the protruding portion protruding from the second bracket 2 is shorter than the length of the terminal accommodating portion 24 protruding from the second bracket 2. In this way, when the insulating frame and the insulating cover plate 6 are connected, interference with the connection between the two is avoided, thereby ensuring the reliability of the connection between the two.

[0192] It can be understood that the second bracket 2 , the third bracket 3 and the first bracket 1 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 24 .

[0193] It can be understood that the second direction is the radial direction of the stator core 4 .

[0194] Embodiment 8:

[0195] like Figure 5 and Figure 9 As shown, according to an embodiment of the present invention, based on the above embodiment, further: the insulating frame also includes: a step portion 28, which is provided on the second bracket 2, and the step portion 28 is located on the side of the protrusion 26 away from the wire groove 20.

[0196] In this embodiment, the insulating frame further includes a step portion 28, which is provided on the second bracket 2 and is used to support the coil, specifically, the step portion 28 is used to support the wire tail of the coil, thereby improving the tightness of the coil winding.

[0197] Specifically, the step portion 28 is arranged on the side of the protrusion 26 away from the wire groove 20, so that the tail part of the coil is wound from the upper surface of the step portion 28 to the bottom of the protrusion 26, and then extends into the wire groove 20, and the tail part of the coil is fixed by the wire groove 20.

[0198] Embodiment 9:

[0199] like Figures 1 to 7 As shown, according to one embodiment of the present invention, on the basis of the above embodiment, further: a plurality of auxiliary grooves 30 are provided on the third bracket 3, any auxiliary groove 30 extends along the first direction, a plurality of auxiliary grooves 30 are distributed along the second direction, and the first bracket 1, the third bracket 3 and the second bracket 2 are distributed in sequence along the second direction.

[0200] In this embodiment, the third bracket 3 is provided with multiple auxiliary slots 30, which secure the coils together, improving the tightness and stability of the coil winding. Each auxiliary slot 30 extends along a first direction, and multiple auxiliary slots 30 are arranged in an array along a second direction. The coils are wound around the insulating frame through the auxiliary slots 30.

[0201] Specifically, the auxiliary groove 30 is provided on the upper surface of the third bracket 3 . When the auxiliary groove 30 naturally extends along the outer surface of the third bracket 3 , it is directly cut by the side surface of the third bracket 3 .

[0202] Embodiment 10:

[0203] like Figure 4 As shown, according to an embodiment of the present invention, based on the above embodiment, further: the inclined portion 22 is close to the edge of the bottom of the second bracket 2 and is substantially flush with the bottom of the auxiliary groove 30.

[0204] In this embodiment, the inclined portion 22 is close to the edge of the bottom of the second bracket 2 and is roughly aligned with the bottom of the auxiliary slot 30, thereby preventing the coil from bending and ensuring the tightness of the coil winding.

[0205] It is understood that the edge of the inclined portion 22 close to the bottom of the second bracket 2 is also the lower edge of the inclined portion 22. The lower edge of the inclined portion 22 is substantially flush with the bottom of the auxiliary groove 30, that is, the lower edge of the inclined portion 22 is flush with the bottom of the auxiliary groove 30, or the lower edge of the inclined portion 22 is slightly higher than the bottom of the auxiliary groove 30.

[0206] Furthermore, the wall surface of the wire trough 20 close to the terminal accommodating portion 24 is substantially flush with the wall surface of the third bracket 3 close to the wire trough 20 .

[0207] In this embodiment, the wall surface of the wire slot 20 close to the terminal accommodating portion 24 is roughly flush with the wall surface of the third bracket 3 close to the wire slot 20. In this way, when the coil is wound from the wire slot 20 to the third bracket 3, the coil can be wound more tightly, thereby improving the slot fill rate of the stator core 4.

[0208] It can be understood that the wall of the wire trough 20 close to the terminal accommodating portion 24 is roughly flush with the wall of the third bracket 3 close to the wire trough 20, that is, the wall of the wire trough 20 close to the accommodating portion is flush with the wall of the third bracket 3 close to the wire trough 20, or there is a small distance between the wall of the wire trough 20 close to the accommodating portion and the wall of the third bracket 3 close to the wire trough 20.

[0209] Example 11:

[0210] like Figure 7 As shown, according to one embodiment of the present invention, on the basis of the above embodiment, further: a cutout 10 is provided on the side of the first bracket 1 facing the second bracket 2, the cutout 10 is arranged close to the bottom of the first bracket 1, and along the first direction, the cutout 10 is located on both sides of the third bracket 3.

[0211] In this embodiment, a cutout 10 is provided on the first bracket 1 . The cutout 10 is located on the inner side of the first bracket 1 and can avoid the winding of the coil, thereby ensuring the tightness of the coil winding.

[0212] Specifically, the incision 10 is located on the side of the first bracket 1 facing the second bracket 2 and is arranged close to the bottom of the first bracket 1. Furthermore, along the first direction, the incision 10 is arranged on both sides of the third bracket 3, thereby reducing the overall weight of the insulating frame and reducing production costs, and avoiding excessive squeezing of the coil by the third bracket 3 and affecting the winding of the coil.

[0213] In practical applications, the wall surface of the first bracket 1 facing the second bracket 2 is approximately flat, while the wall surface of the first bracket 1 facing away from the second bracket 2 is arc-shaped. Consequently, when the insulating frame is applied to the stator, the first bracket 1 can be enclosed into a circular shape to accommodate the shape of the stator teeth, thereby facilitating the installation and movement of the rotor. Furthermore, the provision of the notch 10 allows the shape of the first bracket 1 to adapt to the end of the stator teeth facing the interior of the stator, increasing the stator slot fill ratio and ensuring a tighter overall connection.

[0214] Specifically, the incision 10 is a flat but non-through structure.

[0215] Furthermore, a side of the cutout 10 close to the top of the first bracket 1 is flush with the top of the auxiliary groove 30 .

[0216] In this embodiment, one side of the cutout 10 close to the top of the first bracket 1 is flush with one side of the top of the auxiliary slot 30 , thereby ensuring the coil avoidance effect of the cutout 10 and increasing the slot fill rate of the stator.

[0217] Example 12:

[0218] like Figures 1 to 5 As shown, according to one embodiment of the present invention, on the basis of the above embodiment, further: the insulating skeleton also includes: mark 29, which is provided on at least one of the second bracket 2 and the first bracket 1, and the mark 29 corresponds to the width of the notch 2400 of the terminal accommodating portion 24 and the width of the auxiliary groove 30 of the third bracket 3.

[0219] In this embodiment, the insulating frame also includes a mark 29, which is set on at least one of the second bracket 2 and the first bracket 1. It can be understood that when winding different stators, different coil diameters will correspond, and then different auxiliary slot 30 widths and different slot 2400 widths will correspond. That is, the diameter of the coil is one-to-one corresponding to the width of the slot 2400 and the width of the auxiliary slot 30. Therefore, the diameter of the coil changes synchronously with the width of the slot 2400 and the width of the auxiliary slot 30. Therefore, the embodiment proposed in this application sets a mark 29 on the insulating frame, and the mark 29 corresponds one-to-one to the diameter of the coil, the width of the slot 2400 and the width of the auxiliary slot 30. In this way, different insulating frames can be selected according to different coil diameters based on the mark 29. Specifically, different insulating frames correspond to different sizes of slot 2400 widths and auxiliary slot 30 widths, so that insulating frames of various sizes can adapt to coils of different sizes.

[0220] Specifically, the width of the notch 2400 and the yoke width of the auxiliary slot 30 have various sizes, which can be selected according to actual conditions.

[0221] Specifically, the mark 29 can be a number, a letter, or a symbol with equivalent function.

[0222] In a specific application, the mark 29 is provided on the terminal accommodating portion 24 of the second bracket 2 , and further, the mark 29 is provided on the top of the terminal accommodating portion 24 for easy identification by the user.

[0223] Example 13:

[0224] like Figure 10 and Figure 11As shown, according to the second aspect of the present invention, a stator is further proposed, comprising: a stator core 4, the stator core 4 comprising a plurality of segmented cores connected in sequence, the segmented cores comprising teeth, the teeth of two adjacent segmented cores enclosing a stator slot; and an insulating frame as proposed in any one of the first aspects, the number of insulating frames being multiple, both ends of any segmented core being provided with insulating frames, and a third bracket 3 being arranged opposite to the teeth; and a winding 5, the winding 5 being wound on the teeth and the insulating frame.

[0225] The stator provided in the second aspect of the present invention includes the insulating frame provided in any embodiment of the first aspect, and therefore has all the beneficial effects of the insulating frame.

[0226] Furthermore, the stator includes a stator core 4, which comprises a plurality of sequentially connected segmented cores. The segmented cores include teeth. The teeth of two adjacent segmented cores define stator slots for accommodating windings 5. Each segmented core is provided with an insulating frame at both ends, allowing the windings 5 to be wound around the teeth and the insulating frame, ensuring insulation performance. This winding method also allows for electrical connection of the same-phase windings 5 on the insulating frame, eliminating the need for additional structures for electrical connection. This reduces the axial height of the stator and makes the stator ends more compact.

[0227] Furthermore, the winding 5 includes a plurality of coils. A coil is wound on a segmented iron core and an insulating frame at both ends of the segmented iron core. The coil includes a wire head and a wire tail. The wire slot 20 is used to accommodate the wire head and the wire tail.

[0228] In this embodiment, the winding 5 includes multiple coils, and a segmented iron core and the insulating frames at both ends of the core core constitute an iron core assembly, wherein each iron core assembly is wound with a coil. After each coil is wound, the multiple iron core assemblies are combined into a circle to form a stator, thereby improving the slot fill rate while avoiding scratching the insulation layer on the coil surface.

[0229] The coil includes a wire head and a wire tail, and the wire slot 20 is used to accommodate the wire head and the wire tail to ensure the tightness of the coil winding.

[0230] Specifically, the wire head is clamped in the wire slot 20 at one end of the stator core 4 in the axial direction, then extends to the other end of the stator core 4 and is wound from the side of the insulating frame away from the wire slot 20, so that the wire tail is located on the side of the insulating frame close to the wire slot 20. The wire tail is then wound to the step 28, passes through the upper surface of the step 28 and extends to the bottom of the protrusion 26, and then extends into the wire slot 20, where it is pre-fixed. After all the coils are wound, the multiple segmented cores are combined into a circle to form a stator. Compared with the existing technology, the embodiment proposed in this application can not only improve the slot fill rate of the stator, but also avoid damage to the insulation layer of the coil itself.

[0231] Furthermore, the stator further includes an insulating cover plate 6 , which is arranged on a side of the insulating frame away from the stator core 4 , and is engaged with the protrusion 26 of the insulating frame.

[0232] In this embodiment, the insulation frame also includes an insulation cover plate 6, which is disposed on the side of the insulation frame away from the stator core 4. This arrangement protects the coil ends from curling, improving the safety of the stator. The insulation cover plate 6 is connected to the raised portion 26 of the insulation frame, securing the insulation cover plate 6 and making the overall stator structure more compact, effectively locking the two together.

[0233] Furthermore, the insulating cover plate 6 is engaged with the raised portion 26 of the insulating frame.

[0234] In specific applications, such as Figure 12 As shown, the insulating cover 6 is provided with a buckle 60, which is engaged with the protrusion 26. It can be understood that the length of the protrusion 26 is shorter than the length of the terminal accommodating portion 24, so the engagement of the buckle 60 with the protrusion 26 is guaranteed.

[0235] Furthermore, any segmented core includes a plurality of punching sheets, and the plurality of punching sheets are stacked and distributed along the axial direction of the stator core 4 .

[0236] In this embodiment, each segmented iron core is provided with a plurality of punching sheets, and the plurality of punching sheets are stacked and distributed along the axial direction of the stator iron core 4, so that overlapping portions are formed at the peripheral edges of the punching sheets. When the plurality of punching sheets are stacked and distributed along the axial direction of the iron core, overlapping gaps are defined between adjacent punching sheets and are formed in stator slots, so that the winding 5 is wound on the teeth of the stator iron core 4 and is located in the stator slots.

[0237] Specifically, the punching sheets are silicon steel sheets.

[0238] Furthermore, two adjacent segmented iron cores are rotatably connected via the overlapping portion.

[0239] In this embodiment, two adjacent segmented cores are rotatably connected via the overlapping portion, that is, the two connected segmented cores can rotate relative to each other.

[0240] By rotating and connecting two adjacent segmented cores through the overlapping part, one segmented core can be rotated around the other segmented core with the connection point of the overlapping part as the center of the circle. This connection method is simple and reliable, and it is convenient for the operator to adjust the shape and structure of the stator core 4, and the position of the segmented core can be adjusted according to usage requirements.

[0241] Furthermore, the stator core 4 includes a tooth portion and a yoke portion, and the stator core 4 has at least a first state and a second state; in the first state, a plurality of segmented cores are combined to form a first ring shape, and the tooth portion is located on the inner side of the yoke portion; in the second state, a plurality of segmented cores are unfolded to form a roughly straight line.

[0242] In this embodiment, the stator core 4 has a first state, which is the normal state after the stator core 4 is wound with the windings 5. In this first state, the multiple segmented cores are combined to form a first annular shape, with the teeth located inside the yoke. In this state, the windings 5 are wound into the stator slots formed by adjacent teeth, with the windings 5 close to the inside of the stator core 4. Two adjacent stator cores 4 are rotatably connected by the overlapping portion provided on the outer yoke, together enclosing a circular stator core 4.

[0243] The stator core 4 also has a second state. Because two adjacent segmented cores are rotatably connected, when two adjacent segmented cores in the stator core 4 move relative to each other, the multiple segmented cores can be unfolded to form a roughly straight line. After unfolding, the teeth of each segmented core are arranged roughly in a straight line. In the unfolded state, the space between the stator slots between teeth is increased compared to the first state, making it easier for the operator to wind the winding 5.

[0244] By placing the stator core 4 in the second state, the teeth can be arranged in a roughly linear pattern, and the space in the stator slots can be increased, making it easier for the operator to wind the winding 5. After winding the winding 5, the stator core 4 is closed back to the first state, so that the individual core segments are combined to form a circular stator core 4, ensuring a stable and reliable structure.

[0245] Furthermore, in the second state, the two segmented iron cores at both ends are connected together after being joined into a circle. Specifically, the two segmented iron cores can be welded after being joined into a circle.

[0246] It can be understood that, in the second state, the stator core 4 is substantially in a straight line, including that the stator core 4 is in a straight line, or that the stator core 4 has a certain curvature.

[0247] Furthermore, the plurality of punching sheets include a first punching sheet layer and a second punching sheet layer which are alternately arranged; an overlapping portion is provided on the first side of the first punching sheet layer, the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer, and two adjacent first punching sheet layers enclose an overlapping gap; an overlapping portion is provided on the second side of the second punching sheet layer, the overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer, and two adjacent second punching sheet layers enclose an overlapping gap; in two adjacent segmented iron cores, the overlapping portion of one segmented iron core is inserted into the overlapping gap of the other segmented iron core.

[0248] In this embodiment, the plurality of punching sheets include a first punching sheet layer and a second punching sheet layer, and the plurality of first punching sheets and the plurality of second punching sheets are alternately distributed along the axial direction of the stator core 4. The first punching sheet layer is provided with an overlapping portion on the first side, and the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent first punching sheet layers both protrude from the second punching sheet layer arranged between the two adjacent first punching sheet layers, so that an overlapping gap is enclosed between the two adjacent first punching sheet layers. The second punching sheet layer is provided with an overlapping portion on the second side, that is, the second punching sheet layer is provided with an overlapping portion on a side different from the first punching sheet layer. The overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent second punching sheet layers both protrude from the first punching sheet layer arranged between the two adjacent second punching sheet layers, so that an overlapping gap can also be enclosed between the two adjacent second punching sheet layers.

[0249] It is understood that when the plurality of first punching sheet layers and the plurality of second punching sheet layers are alternately distributed along the circumference of the stator core 4, the overlapping portions of the plurality of first punching sheet layers arranged on the first side are staggered with the overlapping portions of the plurality of second punching sheet layers arranged on the second side. Furthermore, the overlapping gaps between two adjacent first punching sheet layers and the overlapping gaps between two adjacent second punching sheet layers are respectively located on opposite sides of the segmented core and are staggered.

[0250] An overlapping portion and an overlapping gap are respectively provided on the side adjacent to each other of two adjacent segmented iron cores. Since the overlapping portions of multiple first punching sheet layers arranged on the first side are staggered with the overlapping portions of multiple second punching sheet layers arranged on the second side, and the overlapping gaps between two adjacent first punching sheet layers are staggered with the overlapping gaps between two adjacent second punching sheet layers, the overlapping portion of one segmented iron core is inserted into the overlapping gap of another segmented iron core, thereby realizing the connection between the two adjacent segmented iron cores.

[0251] By alternating the first and second punching sheet layers, providing overlapping portions on different sides of the first and second punching sheet layers, and enclosing overlapping gaps on different sides of the first and second punching sheet layers, two adjacent segmented cores can be connected through the overlapping portions and overlapping gaps. Specifically, the overlapping portion of one segmented core is inserted into the overlapping gap of another segmented core. This connection method is stable and reliable, and the operator can quickly disassemble and assemble the stator core 4, thereby improving work efficiency. In addition, multiple segmented cores can be connected to each other using the same structure, which reduces the types of segmented cores, improves the versatility of the segmented cores, and reduces product costs.

[0252] Furthermore, the plurality of punching sheets include a first punching sheet layer and a second punching sheet layer which are alternately arranged; an overlapping portion is provided on the first side of the first punching sheet layer, the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer, and two adjacent first punching sheet layers enclose an overlapping gap; an overlapping portion is provided on the second side of the second punching sheet layer, the overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer, and two adjacent second punching sheet layers enclose an overlapping gap; in two adjacent segmented iron cores, the overlapping portion of one segmented iron core is inserted into the overlapping gap of the other segmented iron core.

[0253] In this embodiment, the plurality of punching sheets include a first punching sheet layer and a second punching sheet layer, and the plurality of first punching sheets and the plurality of second punching sheets are alternately distributed along the axial direction of the stator core 4. The first punching sheet layer is provided with an overlapping portion on the first side, and the overlapping portion on the first punching sheet layer protrudes from the second punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent first punching sheet layers both protrude from the second punching sheet layer arranged between the two adjacent first punching sheet layers, so that an overlapping gap is enclosed between the two adjacent first punching sheet layers. The second punching sheet layer is provided with an overlapping portion on the second side, that is, the second punching sheet layer is provided with an overlapping portion on a side different from the first punching sheet layer. The overlapping portion on the second punching sheet layer protrudes from the first punching sheet layer. Since the plurality of first punching sheet layers and the plurality of second-type punching sheet layers are alternately arranged, the two adjacent second punching sheet layers both protrude from the first punching sheet layer arranged between the two adjacent second punching sheet layers, so that an overlapping gap can also be enclosed between the two adjacent second punching sheet layers.

[0254] It is understood that when the plurality of first punching sheet layers and the plurality of second punching sheet layers are alternately distributed along the circumference of the stator core 4, the overlapping portions of the plurality of first punching sheet layers arranged on the first side are staggered with the overlapping portions of the plurality of second punching sheet layers arranged on the second side. Furthermore, the overlapping gaps between two adjacent first punching sheet layers and the overlapping gaps between two adjacent second punching sheet layers are respectively located on opposite sides of the segmented core and are staggered.

[0255] An overlapping portion and an overlapping gap are respectively provided on the side adjacent to each other of two adjacent segmented iron cores. Since the overlapping portions of multiple first punching sheet layers arranged on the first side are staggered with the overlapping portions of multiple second punching sheet layers arranged on the second side, and the overlapping gaps between two adjacent first punching sheet layers are staggered with the overlapping gaps between two adjacent second punching sheet layers, the overlapping portion of one segmented iron core is inserted into the overlapping gap of another segmented iron core, thereby realizing the connection between the two adjacent segmented iron cores.

[0256] By alternating the first and second punching sheet layers, providing overlapping portions on different sides of the first and second punching sheet layers, and enclosing overlapping gaps on different sides of the first and second punching sheet layers, two adjacent segmented cores can be connected through the overlapping portions and overlapping gaps. Specifically, the overlapping portion of one segmented core is inserted into the overlapping gap of another segmented core. This connection method is stable and reliable, and the operator can quickly disassemble and assemble the stator core 4, thereby improving work efficiency. In addition, multiple segmented cores can be connected to each other using the same structure, which reduces the types of segmented cores, improves the versatility of the segmented cores, and reduces product costs.

[0266] The vehicle provided in the fifth aspect of the present invention includes the compressor proposed in the fourth aspect above, and therefore has all the beneficial effects of the compressor. Specific embodiment:

[0268] like Figures 1 to 11 As shown, the embodiment proposed in the present application provides an insulating frame for a stator, wherein the stator includes a winding 5 wound on the insulating frame.

[0269] The main body of the insulating frame is arranged in a roughly U-shaped configuration and includes a first bracket 1, a second bracket 2, and a third bracket 3. The second bracket 2, the first bracket 1, and the third bracket 3 share a common reference plane. Along one side of the reference plane, the second bracket 2 is larger than the first bracket 1, and the first bracket 1 is larger than the third bracket 3, forming a winding accommodating portion.

[0270] The first bracket 1 has a substantially flat surface on one side close to the winding accommodating portion, and an arc-shaped surface on the other side.

[0271] like Figure 8 and Figure 9 As shown, the second bracket 2 primarily extends in a direction generally perpendicular to the reference plane. The second bracket 2 has a connecting protrusion 27 for engaging with the stator core 4 to secure the insulating frame to the stator core 4. Viewed perpendicular to the reference plane, the protrusion 26, the wire slot 20, and the terminal accommodating portion 24 are arranged in this order.

[0272] The third bracket 3 extends from the reference plane to the winding accommodating portion. On the surface close to the winding accommodating portion, there is an auxiliary groove 30 for assisting the arrangement of coils during winding. The auxiliary grooves 30 are arranged in an array in the direction of the reference plane.

[0273] The protrusion 26 has a protrusion extending along the reference plane. The protrusion is inclined in a direction perpendicular to the reference plane. The outermost edge of the protrusion 26 is shorter than the outermost edge of the terminal accommodating portion 24 .

[0274] The cable duct 20 is divided into an upper and lower halves. The upper half is hollow, while the lower half has a sloped shape, separated by a stepped surface. The upper edge of the slope extends from the stepped surface to the lower edge. The lower edge is approximately aligned with the surface of the auxiliary slot 30 of the third bracket 3.

[0275] On either side of the terminal accommodating portion 24 are slots 2400 for accommodating wires. The upper portion of the slot 2400 is a sloped opening, while the lower portion is approximately U-shaped. In the center of the terminal accommodating portion 240 is a roughly hollow rectangular trough 240 for accommodating crimped terminals. Glue overflow grooves 242 are located on either side of the slot 2400. These grooves are formed as recessed or semi-protruding depressions, or a shape similar to a recessed depression.

[0276] Furthermore, the stepped surface of the wire groove 20 is lower than the lower surface of the outer protruding portion 26 .

[0277] Furthermore, the width of the wire groove 20 is greater than the width of the notch 2400 of the outer terminal accommodating portion 24 .

[0278] Furthermore, a side of the wire trough 20 close to the terminal accommodating portion 24 is substantially aligned with a side of the third bracket 3 close to the protruding portion 26 .

[0279] Furthermore, the terminal accommodating portion 24 has a marking 29 in a direction parallel to the reference plane. The marking 29 can be a number, a letter, or a symbol with equivalent functionality. The marking 29 is designed so that when the wire diameter changes, the width of the notch 2400 of the terminal accommodating portion 24 and the width of the auxiliary slot 30 change synchronously.

[0280] Furthermore, a step portion 28 is provided on a side of the protrusion 26 away from the wire groove 20 , and a width of the step portion 28 is smaller than a width of the wire groove 20 .

[0281] Furthermore, the sum of the widths of the plurality of auxiliary grooves 30 is less than or equal to the width of the main body of the third bracket 3. When the auxiliary grooves 30 naturally extend along the outer surface of the third bracket 3, they are directly intersected by the side surface of the third bracket 3. The highest point where the two extend and intersect is referred to as the side height of the auxiliary groove 30.

[0282] Furthermore, a flat but non-through cutout 10 is provided on the first bracket 1 .

[0283] Furthermore, the height of the cutout 10 is consistent with the height of the side surface of the auxiliary groove 30 .

[0284] Furthermore, there is only one wire slot 20. Compared with the prior art, the present invention only requires one wire slot 20, and the wire slot 20 can accommodate both the wire head and the wire tail, making the coil winding more compact.

[0285] Furthermore, the material of the insulating frame is an insulating material with a temperature resistance of more than 120° C. Specifically, the material of the insulating frame is an insulating material with a long-term temperature resistance of more than 120° C.

[0286] Furthermore, the insulating frame is applied to the stator, the stator is applied to the motor, and the compressor includes the motor.

[0287] Specifically, the vehicle includes a vehicle body and a compressor, and the compressor is disposed in the vehicle body.
