Technical Field

[0003] The present application relates to the technical field of motors, and in particular to an insulating frame, a stator assembly and a motor. Background Art

[0004] Existing motor stator windings typically connect to terminals for electrical connection to other control modules. Common connection methods include piercing terminals and wraparound terminals. Piercing terminals pose a risk of the BMC breaking the enameled wire at the piercing point, resulting in substandard contact resistance and poor end-market performance. Wraparound terminals, on the other hand, have a low level of automation, essentially halving production efficiency.

[0060] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0062] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0063] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0064] Existing motor stator windings typically connect to terminals for electrical connection to other control modules. Common connection methods include piercing terminals and wraparound terminals. Piercing terminals pose a risk of the BMC breaking the enameled wire at the piercing point, resulting in substandard contact resistance and poor end-market performance. Wraparound terminals, on the other hand, have a low level of automation, essentially halving production efficiency.

[0065] In view of this, the use of laser automatic welding for welding not only meets the requirements of high degree of automation and high production efficiency, but also avoids the quality risks of piercing terminals, and can match laser welding to realize automated operations.

[0066] Laser welding requires the wire harness to be as close to the terminal as possible, but the wire harness leading out of the winding usually curls up, resulting in poor laser effect or low welding efficiency.

[0067] In view of this, the present application proposes an insulation frame 20 .

[0068] The insulating frame 20 is used to be installed on one side of the stator core 400, and the wire harness led out of the winding 500 is connected to the welding wire terminal 300 by laser welding, and the specific laser welding method is laser soldering. Laser soldering is a brazing method that uses laser as a heat source to melt so that the weldment fits tightly. Compared with traditional welding processes, this welding method has the advantages of fast heating speed, low heat input and large heat impact. In addition, the welding position of laser soldering can be precisely controlled, the soldering amount can be accurately controlled, and the consistency of the solder joints is high, which is more conducive to use in the welding process of small-volume wire harnesses and terminals. The soldering process is fully automated, which is more in line with the demand for production and processing efficiency.

[0069] In an embodiment of the present application, as shown in Figures 1 to 6, the insulating frame 20 is provided with multiple first wire clamping grooves 210 and multiple second wire clamping grooves 110, and there is an installation position 240 between the multiple first wire clamping grooves 210 and the multiple second wire clamping grooves 110, and the installation position 240 is used to install the welding wire terminal 300.

[0070] Specifically, the insulating frame 20 is mainly used to insulate the stator core 400 from the outside world. The main body of the insulating frame 20 is made of insulating material. The stator core 400 is installed on the insulating frame 20. The stator core 400 can be embedded in the insulating frame 20, or the stator core 400 can be connected to the insulating frame 20. The specific connection method can be snap-in or plug-in, which is not specifically limited here.

[0071] It should be noted that the winding 500 is wound around the insulating frame 20 and the stator teeth of the stator core 400. It should be noted that the stator core 400 has multiple stator teeth, and the insulating frame 20 is provided with multiple tooth portions 120 corresponding to the multiple stator teeth. The winding 500 is wound around the multiple stator teeth and the multiple tooth portions 120 together. The number of stator teeth and tooth portions 120 can be 6, 8, 10, or 12.

[0072] It should be noted that the winding 500 is a general term for the wire harness group wound around multiple stator teeth and multiple tooth parts 120. The multiple wire harnesses led out of the winding 500 are used to be welded to the welding wire terminals 300, thereby electrically connecting the motor to other components.

[0073] Considering that the process used to weld the wire harness to the wire terminal 300 in this embodiment is laser automatic welding, the wire harness needs to be sufficiently close to the wire terminal 300. However, the wire ends of the wire harness often warp, resulting in poor laser automatic welding results. In view of this, a plurality of first wire-holding slots 210 and a plurality of second wire-holding slots 110 are provided on the insulating frame 20, and the wire terminal 300 is located between any one of the wire-holding slots and any one of the second wire-holding slots 110. In this way, the first wire-holding slots 210 and the second wire-holding slots 110 can respectively restrict the wire harness to two positions on opposite sides of the wire terminal 300, thereby preventing the wire harness from warping near the welding position between the wire harness and the wire terminal 300. In addition, the first wire-holding slots 210 and the second wire-holding slots 110 also have the function of bundling the wire harness, making the arrangement of the wire harness more neat.

[0074] Each first wire clamping slot 210 may limit only one wire harness, two wire harnesses, or more wire harnesses. The number of wire harnesses is not specifically limited here.

[0075] The technical solution of the present application adopts a method in which a first wire clamping groove 210 and a second wire clamping groove 110 are provided on the insulating frame 20, and the welding wire terminal 300 is provided between the first wire clamping groove 210 and the second wire clamping groove 110. The wiring harness is respectively clamped in the first wire clamping groove 210 and the second wire clamping groove 110, thereby preventing the wiring harness from warping near the welding wire terminal 300, thereby improving the welding quality of the welding wire terminal 300 and the wiring harness through laser automatic welding, and improving the welding yield of the welding wire terminal 300 and the wiring harness.

[0076] In one embodiment, referring to Figures 1, 2, 5 and 6, the insulating frame 20 includes a frame body 100 and a welding platform 200 connected to each other, the multiple first wire clamping grooves 210 are opened on the welding platform 200, and the multiple second wire clamping grooves 110 are opened on the frame body 100.

[0077] It should be noted that the insulating frame 20 includes a connected frame body 100 and a welding platform 200. The frame body 100 is arranged in a generally circular shape, and the welding platform 200 is protruding from the outside of the frame body 100. A plurality of welding wire terminals 300 are connected to the welding platform 200 and are arranged on the welding platform 200 at intervals. The plurality of welding wire terminals 300 and the welding platform 200 can be glued, clamped, or welded together, without specific limitation herein. The separate provision of the frame body 100 and the welding platform 200 allows only the welding platform 200 to be placed under the laser welding equipment during the automatic laser welding process, preventing the frame body 100 or other parts of the motor from being affected. A first wire trough 210 is provided on the welding table 200, while multiple second wire troughs 110 are provided on the frame body 100. Considering that multiple welding wire terminals 300 are provided on the welding table 200, the first wire trough 210 should be located on the side of the welding wire terminals 300 away from the second wire trough 110. Furthermore, the wire harness first passes through the second wire trough 110 to the welding wire terminals 300 before reaching the first wire trough 210. Multiple wire harnesses can be confined within a single second wire trough 110 and then individually routed to multiple first wire troughs 210. Alternatively, multiple wire harnesses can be confined within multiple second wire troughs 110 and then individually routed to multiple first wire troughs 210. Alternatively, multiple wire harnesses can be confined within multiple second wire troughs 110 and then routed to a single wire trough.

[0078] In one embodiment, referring to FIG. 2 , the plurality of first wire-clamping slots 210 and the plurality of second wire-clamping slots 110 are disposed in a one-to-one correspondence.

[0079] Furthermore, according to the previous embodiment, in this embodiment, multiple first wire clamping grooves 210 and multiple second wire clamping grooves 110 are arranged in a one-to-one correspondence, that is, a wire harness passing through any second wire clamping groove 110 has a corresponding first wire clamping groove 210. In this way, multiple wire harnesses can be arranged neatly and do not interfere with each other during the welding process.

[0080] In one embodiment, referring to Figures 2 and 3, a plurality of spaced-apart wire-clamping platforms 220 are provided on the welding platform 200, and the plurality of first wire-clamping grooves 210 are respectively opened on the plurality of wire-clamping platforms 220. The first wire-clamping grooves 210 have a first opening 211, and the first opening 211 is used to place the wire harness into the first wire-clamping groove 210. The first wire-clamping grooves 210 respectively penetrate two oppositely arranged walls of the wire-clamping platform 220 for allowing the wire harness to pass through.

[0081] It should be noted in detail that the wire clamping platform 220 is protruding from the welding platform 200, and the first wire clamping slot 210 is provided on the wire clamping platform 220. Each wire clamping platform 220 has only one first wire clamping slot 210, and each first wire clamping slot 210 only holds one wire harness. The first wire clamping slot 210 has a first opening 211, allowing the wire harness to be placed into the first wire clamping slot 210 through the first opening 211, facilitating the clamping of the wire harness within the first wire clamping slot 210. The first wire clamping slot 210 extends through two opposing walls of the wire clamping platform 220 along the wire harness's lead-out path, allowing the wire harness to pass in and out of the first wire clamping slot 210.

[0082] For example, referring to FIG. 3 , the first wire-holding slot 210 has two slot walls 212 that are opposite to each other, and the two slot walls 212 are respectively provided with corresponding limiting protrusions 212 a.

[0083] It should be noted that the first wire-retaining slot 210 has two opposing slot walls 212, each of which is provided with a corresponding limiting protrusion 212a. The two limiting protrusions 212a are integrally formed with the two slot walls 212. The provision of the two limiting protrusions 212a reduces the distance between the two slot walls 212. The two limiting protrusions 212a confine the wiring harness to the lower side of the two limiting protrusions 212a, preventing the wiring harness from moving above the limiting protrusions 212a, thereby preventing the wiring harness from being positioned too high within the first wire-retaining slot 210. Furthermore, the limiting protrusions 212a can be positioned above, in the middle of, or below the slot walls 212, without specific limitation herein.

[0084] In one embodiment, referring to FIG. 3 , the width of the first wire-locking groove 210 gradually decreases along a direction from the first opening 211 to the limiting protrusion 212 a .

[0085] The explanation of the above embodiment has explained that the wire harness is placed in the first wire clamping groove 210 from the first opening 211. Furthermore, in order to make it easier to place the wire harness in the first wire clamping groove 210, the slot of the first wire clamping groove 210 is set to be open. Specifically, the width of the first wire clamping groove 210 gradually decreases from the first opening 211 to the limiting protrusion 212a, and the width of the first clamping groove under the limiting protrusion 212a is basically the same.

[0086] In one embodiment, referring to FIG. 3 , the distance between the two limiting protrusions 212 a is L1 , and L1 satisfies 0.53 mm ≤ L1 ≤ 0.58.

[0087] It should be noted that the diameter of the wire harness in this embodiment is uniformly set to approximately 0.6 mm. To constrain the wire harness below the limiting protrusion 212a and prevent it from moving above the limiting protrusion 212a, the distance between the two limiting protrusions 212a is set to be less than or equal to 0.58 mm. It should be further noted that the wire harness is made of copper, which has a slight elasticity. Therefore, the distance between the two limiting protrusions 212a can be slightly smaller than the diameter of the wire harness. To ensure that the wire harness can be smoothly placed from the first opening 211 into the first wire retaining groove 210, the distance between the two limiting protrusions 212a cannot be set too small. Therefore, the distance between the two limiting protrusions 212a is set to be greater than or equal to 0.53 mm. The distance between the two limiting protrusions 212a can be any value within the range of 0.53 mm to 0.58 mm. It should also be noted that the surface of the limiting protrusion 212 a in this embodiment has a certain curvature, and L1 represents the minimum distance between the two limiting protrusions 212 a.

[0088] Furthermore, referring to Figure 3 , the two limiting protrusions 212a are located in the middle of the two groove walls 212, respectively. According to the above embodiment, the middle of the groove wall 212 is approximately halfway through the depth of the first wire-retaining groove 210. The limiting protrusions 212a are located in the middle of the groove wall 212. The height of the limiting protrusions 212a should not be too high, thereby reducing their limiting effect; nor should they be too low, thereby making it difficult to place the wiring harness below the limiting protrusions 212a.

[0089] In one embodiment, referring to Figures 2 and 6, the second wire clamping groove 110 is opened on the periphery of the frame body 100, and the second wire clamping groove 110 has a second opening 111. The second opening 111 is used to place the wire harness into the second wire clamping groove 110. The second wire clamping groove 110 passes through the opposite sides of the periphery of the frame body 100 for the wire harness to pass through.

[0090] Specifically, the second wire-holding slot 110 is provided around the periphery of the frame body 100, and the periphery of the frame body 100 may be arranged to protrude in a direction away from the stator core 400. The second wire-holding slot 110 is positioned near the welding table 200 and has a second opening 111, allowing a wire harness to be placed into the second wire-holding slot 110 through the second opening 111, facilitating the securing of the wire harness within the second wire-holding slot 110. Furthermore, the second wire-holding slot 110 extends through two opposing walls of the wire-holding table 220 on the wire harness's lead-out path, allowing the wire harness to pass in and out of the second wire-holding slot 110.

[0091] In one embodiment, referring to FIG. 4 , the outer periphery of the second wire-locking slot 110 close to the inner side of the frame body 100 is configured to be arc-shaped and expanded.

[0092] Specifically, it should be noted that in order to make it easier for the wiring harness led out from the winding 500 to be introduced into the second wire clamping groove 110, the outer periphery of the second wire clamping groove 110 close to the inner side of the frame body 100 is set to be flared, and the flared design is arc-shaped, which is smoother than other shapes with edges and corners, and it is easier to introduce the wiring harness into the second wire clamping groove 110.

[0093] In one embodiment, referring to FIG. 4 , the width of the second wire-locking slot 110 is L2 , and L2 satisfies 0.58 mm ≤ L2 ≤ 0.63 mm.

[0094] Specifically, the diameter of the wire harness in this embodiment is approximately 0.6 mm. It should be noted that the wire harness has a certain degree of elasticity. Considering that the second wire retaining groove 110 should restrain the wire harness from tilting upward, the width of the second wire retaining groove 110 is set to be less than or equal to 0.63 mm. Furthermore, considering that the wire harness will pass through the first wire retaining groove 210 after passing through the second wire retaining groove 110, the width of the second wire retaining groove 110 should not be too small. Therefore, the width of the second wire retaining groove 110 is set to be greater than or equal to 0.58 mm. Therefore, the width of the second wire retaining groove 110 can be any value within the range of 0.58 mm to 0.63 mm.

[0095] In one embodiment, referring to Figures 2 and 5, the frame body 100 is provided with a plurality of teeth 120 for winding the winding 500 toward the interior thereof, and the plurality of teeth 120 are respectively provided with a plurality of first baffles 121 near the outside of the frame body 100, and the outer protrusion of the frame body 100 is provided with a rib 130, and the rib 130 and the plurality of first baffles 121 are spaced apart to limit the wiring harness led out of the winding 500.

[0096] It should be noted that to prevent the winding 500 wound on the tooth portion 120 from falling off the insert 140, a plurality of first baffles 121 are provided on the outer side of the frame body 100, with each first baffle 121 corresponding one-to-one with the tooth portion 120. Furthermore, a plurality of second baffles 122 are provided on the inner side of the tooth portion 120, near the frame body 100. Each of the plurality of second baffles 122 corresponds one-to-one with the tooth portion 120, and each of the plurality of second baffles 122 corresponds one-to-one with the first baffle 121, respectively, to position the winding 500 on opposite sides, preventing it from falling off the tooth portion 120. A rib 130 is formed on the outer side of the frame body 100, extending away from the stator core 400. The rib 130 and the plurality of first baffles 121 are spaced apart to limit the wiring harness leading out of the winding 500. The first baffles 121 and the second baffles 122 are injection molded with the tooth portion 120, respectively.

[0097] This arrangement is because the conventional design for limiting the lead-out wiring harness of the winding 500 is to provide a plurality of staggered blocks on the outside of the first baffle 121 close to the frame body 100, and clamp the wiring harness of the winding 500 between the plurality of blocks. However, this method can easily cause the wiring harness to be pulled and broken during injection molding of the insulating frame 20 and the motor housing or other components. Therefore, the above-mentioned method is adopted to prevent the wiring harness from being pulled, deformed or even broken.

[0098] In one embodiment, referring to FIG. 1 and FIG. 2 , the retaining edge 130 is disposed around the plurality of first retaining plates 121 close to the welding station 200 .

[0099] It should be noted that it is possible that the windings 500 on each tooth portion 120 will lead out a wiring harness, or it is possible that the windings 500 on a portion of the tooth portions 120 will lead out a wiring harness. When the windings 500 on each tooth portion 120 will lead out a wiring harness, the retaining edge 130 needs to be set around all the first baffles 121. However, in the present embodiment, only the windings 500 on the tooth portions 120 of the multiple first baffles 121 close to the welding station 200 will lead out a wiring harness, so the baffles only need to be set around the above-mentioned windings 500. Therefore, in the present embodiment, the baffles are set around half of the outer circumference of the frame body 100. It should be noted that the number of the multiple first baffles 121 here can be three, four, or six, and is not specifically limited here.

[0100] In one embodiment, referring to FIG. 6 , a plurality of reinforcing ribs 131 are disposed at intervals on the outer periphery of the retaining edge 130 .

[0101] Considering that the thickness of the rib 130 is relatively thin, a plurality of reinforcing ribs 131 are provided at intervals on the outer periphery of the rib 130 to reinforce the structure of the rib 130 and prevent the rib 130 from breaking or cracking.

[0102] Furthermore, referring to FIG. 2 and FIG. 6 , the plurality of second wire-gripping grooves 110 are distributed at intervals on the rib 130 .

[0103] In the above embodiment, a plurality of second wire-clamping grooves 110 are provided on the periphery of the frame body 100 . In the above embodiment, it has been described that a rib 130 is provided on the periphery of the frame body 100 , and the rib 130 is close to the welding table 200 , so the plurality of second wire-clamping grooves 110 are spaced apart and arranged on the rib 130 .

[0104] This application also provides a stator assembly 10, comprising the aforementioned insulating frame 20, a stator core 400, and a plurality of welding terminals 300. The plurality of welding terminals 300 are disposed on the mounting positions 240, and the insulating frame 20 is mounted on one side of the stator core 400. The specific structure of the insulating frame 20 is similar to that of the aforementioned embodiments. Since this motor utilizes all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and therefore will not be further elaborated here.

[0105] In one embodiment, referring to FIG. 7 , the welding platform 200 has a first surface 230 , on which a mounting platform 231 is protruded. The mounting platform 231 has a first slot 231 a formed therein, and the welding wire terminal 300 is at least partially inserted into the first slot 231 a .

[0106] It should be noted that the welding table 200 has a first surface 230, which is located on a side away from the stator core 400. It should be noted that a mounting table 231 for mounting the welding wire terminal 300 is provided on the first surface 230. Specifically, a first slot 231a is provided on the mounting table 231. The welding wire terminal 300 is inserted into the first slot 231a. The welding wire terminal 300 can be fully inserted into the first slot 231a or partially inserted into the first slot 231a. Considering that a part of the welding wire terminal 300 needs to be welded outside, in this embodiment, the welding wire terminal 300 is partially inserted into the first slot 231a, and the notch of the first slot 231a corresponds to the strip shape of the welding wire terminal 300.

[0107] Further, referring to Figures 7 and 8, the mounting platform 231 includes a first stage 231b and a second stage 231c connected to each other, and the welding wire terminal 300 includes a plug-in portion 310 and a welding portion 320. The plug-in portion 310 is inserted into the first slot 231a, and the welding portion 320 is arranged on one side of the first stage 231b. The height of the first stage 231b relative to the first surface 230 is less than the height of the second stage 231c relative to the first surface 230.

[0108] It should be noted that the mounting platform 231 comprises a first stage 231b and a second stage 231c, which are connected and integrally formed by injection molding in this embodiment. The wire soldering terminal 300 comprises two parts: a plug-in portion 310, which inserts into the first slot 231a, and a welding portion 320, which is used for laser welding with the wiring harness. The welding portion 320 is positioned to one side of the first stage 231b. Considering the diffuse reflection generated during laser welding, which still generates high light temperatures, and the proximity of the first stage 231b to the welding portion 320, which could potentially cause fire, the first stage 231b is positioned offset from the first surface 230. This height of the first stage 231b is smaller than the height of the second stage 231c relative to the second surface. This reduces the height of the first stage 231b, significantly minimizing the risk of fire caused by diffuse laser reflection.

[0109] In addition, the welding wire terminal 300 may also have only the welding portion 320. The structure of the welding wire terminal 300 in this embodiment is only one type of the structure of the welding wire terminal 300. It does not mean that the structures of the welding wire terminals 300 in the above embodiments are the same as the structure of the welding wire segment in this embodiment, nor does it mean that all the structures of the welding wire terminals 300 in this solution are the same as the structure of the welding wire terminal 300 described in this embodiment.

[0110] Further, referring to FIG. 7 , the height of the first stage 231 b relative to the first surface 230 is H, and H satisfies 0.3 mm ≤ H ≤ 0.6 mm.

[0111] It should be noted that, considering that the height of the first stage 231b relative to the first surface 230 should not be too high, otherwise there may be a fire risk in the first stage 231b, the height of the first stage 231b relative to the first surface 230 is set to be less than or equal to 0.60 mm. In addition, a second slot 410 for inserting the plug-in portion 310 is formed on the first stage 231b, so the height of the first stage is greater than or equal to 0.3 mm, so that the plug-in portion 310 is limited by the opposite sides of the first stage 231b.

[0112] In one embodiment, referring to Figures 1, 6 and 9, a plurality of spaced-apart inserts 140 are provided on one side of the frame body 100 close to the stator core 400, and a plurality of second slots 410 are opened on the stator core 400 corresponding to the inserts 140, and the plurality of inserts 140 are respectively inserted into the plurality of second slots 410.

[0113] Specifically, the plurality of inserting portions 140 correspond one-to-one with the plurality of second slots 410. In this embodiment, the inserting portions 140 are cylindrical, but may also be prismatic, pyramidal, or have other shapes. The shape of the second slots 410 matches the shape of the first slots 231a. The cooperation between the inserting portions 140 and the second slots 410 provides a positioning effect for the insulation frame 20 and the stator core 400, as well as a fixed assembly effect. The number of inserting portions 140 and the second slots 410 can be two, three, or even more, and is not specifically limited herein.

[0114] In one embodiment, referring to Figures 1, 6 and 9, a plurality of protrusion structures 420 are provided on the periphery of the stator core 400 at intervals, and openings 423 are provided on the protrusion structures 420. A plurality of positioning structures 150 are provided on the periphery of the insulating frame, and the positioning structures 150 are aligned with the openings 423.

[0115] It should be noted that, in this embodiment, each protrusion structure 420 has only one opening 423, and opening 423 is located approximately in the middle of the protrusion structure 420. The outer periphery of the insulating frame is provided with a positioning structure corresponding to the opening 423. This positioning structure can be a protrusion, a groove, or a hole, and is not specifically limited here. By aligning the positioning structure 150 with the opening 423, the insulating frame and the stator core 400 are aligned and installed.

[0116] In one embodiment, referring to Figures 1, 6 and 9, the protrusion structure 420 includes two first protrusions 421 and one second protrusion 422, the distance between the two first protrusions 421 is smaller than the distance from any first protrusion 421 to the second protrusion 422, the number of the positioning structures 150 is set to two, and the two positioning structures 150 are respectively set to correspond to the openings 423 of the two first protrusions 421.

[0117] It should be noted that, considering that there is an obvious difference in positional distance between the second protrusion 422 and the two first protrusions 421 and the two first protrusions 421, only two positioning structures 150 are provided to meet the alignment of the positioning structure 150 and the opening 423. Such a setting can reduce the mold opening cost of the insulating frame 20.

[0118] In one embodiment, referring to FIG. 1 , FIG. 6 and FIG. 9 , the positioning structure 150 includes a positioning platform 151 protruding from the outer periphery of the frame body 100 , and the positioning platform 151 is disposed corresponding to the opening 423 .

[0119] According to the above embodiment, the positioning structure 150 is a protruding positioning platform 151 , and the positioning platform 151 is aligned with the opening 423 to achieve alignment between the insulation frame 20 and the stator core 400 .

[0120] Furthermore, referring to FIG. 1 , FIG. 6 and FIG. 9 , the positioning platform 151 defines a positioning groove 151 a corresponding to the opening 423 .

[0121] On the basis of the above embodiment, a positioning groove 151a is further provided on the positioning platform 151. When the positioning groove 151a is aligned with the opening 423, the insulating frame 20 and the stator core 400 can be aligned, which enhances the alignment accuracy of the insulating frame 20 and the stator core 400 compared with the above embodiment.

[0122] Furthermore, referring to FIG. 1 , FIG. 6 and FIG. 9 , the groove wall 212 of the positioning groove 151 a is configured to be curved corresponding to the opening 423 .

[0123] On the basis of the above embodiment, the groove wall 212 of the positioning groove 151a is arranged to be curved corresponding to the opening 423. In this way, when the groove wall 212 of the positioning groove 151a is aligned or offset with the hole wall of the opening 423, the alignment of the insulating frame 20 and the stator core 400 can be ensured, which further enhances the alignment accuracy of the insulating frame 20 and the stator core 400 compared with the above embodiment.

[0124] The wiring harness leading from the stator windings of existing motors is typically connected to terminals to facilitate electrical connection to other control modules. The wiring harness is typically positioned outside a baffle on the insulation frame, with several staggered bumps positioned on the outside of the baffle to guide the wiring harness between them. However, once the wiring harness is positioned, the insulation frame and other components may be subjected to significant pressure during the injection molding process, causing it to be pulled, damaged, or even broken.

[0125] In view of this, the present application proposes an insulation frame 20 .

[0126] In an embodiment of the present application, as shown in Figures 10, 11 and 5, the insulating frame includes a frame body 100 arranged in a ring shape, and a plurality of teeth 120 for winding the winding 500 are provided on the inner side of the frame body 100. The frame body 100 is provided with a plurality of first baffles 121 protruding along its axial direction. The outer periphery of the frame body 100 extends along the axial direction of the frame body 100 to form a skirt 620. The skirt 620 extends along the axial direction of the frame body 100. The skirt 620 is arranged on the periphery of the plurality of first baffles 121, and there is a gap between the skirt 620 and the plurality of skirts 121 for bundling the wire harness led out of the winding 500.

[0127] It should be noted that the frame body 100 is mounted on the stator core 400. The frame body 100 has an opening in the middle, and a plurality of teeth 120 are protruding from the frame body 100 toward the inside. The plurality of teeth 120 correspond to the plurality of stator teeth on the stator core 400. The windings 500 are wound around the plurality of stator teeth and the plurality of teeth 120. The windings 500 wound around the stator teeth and the teeth 120 lead to a wiring harness. However, it should be noted that the windings 500 wound around all or only some of the stator teeth and the teeth 120 may lead to a wiring harness, and this is not specifically limited here. The teeth 120 are integrally molded with the frame body 100.

[0128] The number of the teeth 120 corresponds to the number of the stator teeth. The number of the teeth 120 can be 6, 8, 10, 12 or even more, which is not specifically limited here.

[0129] First, the frame body 100 is provided with a plurality of first baffles 121 in its axial direction. The plurality of first baffles 121 may correspond to the plurality of teeth 120 respectively, or may not correspond to the plurality of teeth 120. On this basis, the outer periphery of the frame body 100 is also formed with a skirt 620 along the axial direction of the frame body 100, that is, the skirt 620 is located outside the plurality of first baffles 121, and there must be a gap between the skirt 620 and the plurality of first baffles 121 so that the wiring harness can pass therebetween. The wiring harness led out from the winding 500 is attached to the inner wall of the skirt 620, so that the wiring harness group can be arranged. This method can also prevent the wiring harness from being compressed, pulled, deformed, damaged or even broken when the insulating frame 20 and other components are injection molded.

[0130] The technical solution of the present application adopts the method of arranging a plurality of first baffles 121 and skirts 620 in the axial direction of the frame body 100, so as to place the wiring harness led out of the winding 500 in the gap between the two, thereby preventing the wiring harness from being damaged or even broken by being pulled under pressure during injection molding of the insulating frame 20 and other components.

[0131] Furthermore, referring to FIG. 10 to FIG. 12 , the plurality of first baffles 121 correspond to the plurality of teeth 120 in a one-to-one manner.

[0132] It should be noted that the function of the multiple first baffles 121 is not limited to limiting the wiring harnesses led out of the multiple windings 500. Considering that the winding 500 is wound on the tooth portion 120, the first baffle 121 corresponds to the tooth portion 120, that is, the first baffle 121 can limit the winding 500 to one side close to the first baffle 121, so that the wiring harness of the winding 500 is neat, and prevent the winding 500 from being arranged in a disorderly manner, thereby affecting the injection molding of the insulating frame 20 structure.

[0133] In one embodiment, referring to FIG. 10 , FIG. 11 and FIG. 5 , the insulating frame 20 further includes a welding platform 200 connected to the frame body 100 , and the skirt 620 is located between the welding platform 200 and the plurality of first baffles 121 .

[0134] Specifically, the welding table 200 is a part used to weld the wire harness led out of the winding 500 to the terminal. The welding table 200 is arranged in a square table in this embodiment, but it can of course be of other shapes. Specifically, in this embodiment, the wire harness led out of the winding 500 is connected to the welding wire terminal by laser welding, and the specific laser welding method is laser soldering. Laser soldering is a brazing method that uses a laser as a heat source to melt so that the weldment fits tightly. Compared with traditional welding processes, this welding method has the advantages of fast heating speed, low heat input and large heat impact. In addition, the welding position of laser soldering can be precisely controlled, the soldering amount can be accurately controlled, and the consistency of the solder joints is high, which is more conducive to use in the welding process of small-volume wire harnesses and terminals. The soldering process is fully automated, which is more in line with the demand for production and processing efficiency.

[0135] In this embodiment, the skirt 620 is only arranged on the outside of multiple first baffles 121 close to the welding table 200. It should be noted that the baffle of this embodiment has twelve teeth 120, and twelve first baffles 121 are provided corresponding to the twelve teeth 120. Only the windings 500 on the teeth 120 corresponding to the six first baffles 121 close to the welding table 200 have lead-out wire harnesses, so the skirt 620 only needs to surround the outside of these six first baffles 121. Of course, the embodiment in which the baffle surrounds all the teeth 120 is also within the protection scope of the above embodiment.

[0136] For example, the ratio of the length of the skirt 620 in the circumferential direction of the frame body 100 to the circumference of the frame body 100 is in the range of 1 / 4 to 1. Furthermore, the length of the skirt 620 in the circumferential direction of the frame body 100 is half of the circumference of the frame body 100.

[0137] According to the above description, the windings 500 on only six of the twelve teeth 120 have lead-out wire harnesses, and the twelve teeth 120 are arranged at equal intervals in the circumferential direction of the frame body 100. Therefore, the circumferential length of the skirt 620 in the frame body 100 only needs to be half of the circumference of the frame body 100 to meet the requirements of the lead-out wire harnesses of the limiting winding 500. However, the above embodiment is only the optimal embodiment of this application and is not limited to this embodiment. The number of teeth 120 and first baffles 121 can be less than twelve or more than twelve, and the number of teeth 120 with lead-out wire harnesses can be half of all teeth 120, more than half of the teeth 120, or less than half of the teeth 120. Therefore, the ratio of the length of the skirt 620 in the circumferential direction of the frame body 100 to the circumference of the frame body 100 is limited to 1 / 4-1.

[0138] In one embodiment, referring to FIG. 10 and FIG. 13 , the skirt 620 is provided on the inclined surfaces 132 at both ends of the frame body 100 in the circumferential direction.

[0139] It should be noted that in order to enhance the structural strength of both ends of the frame body 100 in the circumferential direction, the guide slopes 132 are provided at both ends, which can reduce the impact force of the skirt 620 during the BMC injection molding process and prevent the skirt 620 from being exposed outside the periphery of the frame body 100.

[0140] In one embodiment, referring to FIG. 11 and FIG. 12 , a plurality of wire-holding grooves 610 are formed on a side of the skirt 620 close to the welding platform 200 .

[0141] It should be noted that the wire harness led out of the winding 500 needs to be further introduced from the frame body 100 to the welding table 200 for laser automatic welding, so a wire clamping groove 610 is provided on the side of the skirt 620 close to the welding table 200. On the one hand, the wire clamping groove 610 is provided to allow the wire harness to pass through the skirt 620 and enter the welding table 200. On the other hand, the wire clamping groove 610 has the function of limiting the position of the wire harness. The diameter of the wire harness in this application is approximately 0.6 mm, and the width of the wire clamping groove 610 is set at 0.58 mm-0.63 mm. Therefore, the width of the wire clamping groove 610 is basically consistent with the diameter of the wire harness. Therefore, the wire clamping groove 610 can better limit the wire harness and prevent it from warping upward, thereby resulting in poor welding effect of the wire harness.

[0142] In one embodiment, referring to FIG. 12 , the outer periphery of the wire clamping groove 610 close to the inner side of the frame body 100 is configured to be arc-shaped and expanded.

[0143] Specifically, in order to make it easier for the wire harness led out from the winding 500 to enter the wire clamping groove 610, the outer periphery of the wire clamping groove 610 near the inner side of the frame body 100 is set to be flared, and the flared design is arc-shaped, which is smoother than other shapes with edges and corners, and it is easier to lead the wire harness into the wire clamping groove 610.

[0144] In one embodiment, referring to FIG. 10 , a plurality of reinforcing ribs 131 are disposed at intervals on the outer periphery of the skirt 620 .

[0145] Considering the relatively thin thickness of the skirt 620, a plurality of reinforcing ribs 131 are provided at intervals around the periphery of the skirt 620 to reinforce the structure of the skirt 620 and prevent the skirt 620 from breaking or cracking. Furthermore, the provision of the reinforcing ribs 131 also stabilizes the structure during injection molding, increasing the ability of the skirt 620 to resist impact forces.

[0146] 10 to 12 , a plurality of second baffles 122 are respectively provided at positions of the plurality of teeth portions 120 away from the outer periphery of the frame body 100 , and the plurality of second baffles 122 correspond one-to-one to the plurality of first baffles 121 .

[0147] Furthermore, considering that the above-mentioned multiple first baffles 121 are used to limit the winding 500 close to one side of the baffle, in this embodiment, multiple second baffles 122 are provided, and the second baffles 122 are away from the outer periphery of the frame body. The second baffles 122 and the first baffles 121 respectively limit the winding 500 wound on the tooth portion 120 on the opposite sides of the tooth portion 120, so that the arrangement of the winding 500 is neat and beautiful.

[0148] In one embodiment, referring to FIG. 10 and FIG. 5 , the frame body 100 is arranged in a ring shape.

[0149] In addition, in this embodiment, the frame body 100 is arranged in a ring shape, so it corresponds to the shape of the stator core 400 and has better protection performance for the structure of the stator core 400.

[0150] An insulating frame is typically installed around the stator core of a motor to insulate the stator core. The insulating frame is typically mounted on the stator core. A common assembly method involves plugging the stator core and insulating frame together. However, technicians typically operate from a bird's-eye view, where the plug-in structure is invisible and difficult to align, complicating the insertion and mating of the insulating frame and stator core.

[0151] In view of this, the present application proposes a stator assembly 10 .

[0152] In the embodiment of the present application, as shown in Figures 14 to 18, the stator assembly 10 includes a stator core 400 and an insulating frame 20. A plurality of protrusions 420 are provided at intervals on the outer periphery of the stator core 400. The insulating frame 20 is mounted on the stator core 400. The insulating frame 20 includes a frame body 100. A positioning portion 113 is provided on a side of the frame body 100 close to the stator core 400. The stator core 400 is provided with an insertion hole 730 corresponding to the positioning portion 113. The positioning portion 113 matches the insertion hole 730.

[0153] A plurality of positioning structures 150 are provided on the periphery of the frame body 100 . When the positioning portion 113 is engaged with the insertion hole 730 , the positioning structures 150 are provided correspondingly to the protruding structures 420 .

[0154] Specifically, the stator assembly 10 primarily consists of a stator core 400 and an insulating frame 20 mounted on the stator core 400. After the stator core 400 and insulating frame 20 are assembled, a winding 500 is wound around the stator core 400 and insulating frame 20. The stator core 400 has a plurality of stator teeth formed as protrusions toward its interior, while the insulating frame 20 is provided with a plurality of tooth portions corresponding to the plurality of stator teeth. The plurality of tooth portions corresponds one-to-one with the plurality of stator teeth. A winding 500 is wound around each stator tooth and tooth portion.

[0155] The outer periphery of the stator core 400 is provided with a plurality of protruding structures at intervals. The protruding structures 420 are used for assembly with the motor housing. The number of the protruding structures 420 can be two, three, or more, which is not specifically limited here.

[0156] The insulating frame 20 includes at least a frame body 100. The frame body 100 is a frame-like design with an internal opening. The frame body 100 can be square, oval, or circular. Since the main portion of the stator core 400 in this embodiment is annular, the frame body 100 is also annular. The insulating frame 20 may consist solely of the frame body 100 or may include other components in addition to the frame body 100. This is not specifically limited herein.

[0157] The insulating frame 20 and the stator core 400 can be assembled by an interference fit, a plug-in structure, or a snap-fit ​​structure. In this embodiment, the insulating frame 20 and the stator core 400 are connected by plug-fitting. A positioning portion 113 is provided on the frame body 100, and a socket 730 that cooperates with the positioning portion 113 is provided on the stator core 400. The positioning portion 113 is inserted into the socket 730 to fix the relative position of the insulating frame 20. Since both the frame body 100 and the stator core 400 are arranged in a circular ring shape, the plug-fitting can also prevent the insulating frame 20 from rotating relative to the stator core 400. Of course, in other embodiments, the positioning portion 113 can also be provided on the stator core 400, and the socket 730 can be provided on the insulating frame 20. This method can be simply deduced by those skilled in the art based on the above embodiment.

[0158] It should be noted that when the operator assembling the stator assembly 10 installs the insulating frame 20 on the stator core 400, he faces the stator assembly 10 from a top-down perspective. The positioning portion 113 and the socket 730 in this embodiment are relatively small in size, so it is difficult to accurately align them in a blind field during the assembly process. Therefore, a plurality of positioning structures 150 are provided on the periphery of the frame body 100. The positioning structure 150 has an anti-mistake effect. The positioning structure 150 is aligned with the raised structure 420 on the periphery of the stator core 400, thereby reducing the difficulty of inserting the positioning portion 113 into the socket 730 and reducing the difficulty of assembling the insulating frame 20 and the stator core 400. It should be noted that the alignment of the positioning structure 150 and the protruding structure 420 is such that, when the positioning portion 113 is mated with the insertion hole 730, the positioning structure 150 is located near the protruding structure 420, or the positioning structure 150 and the protruding structure 420 partially overlap, or the positioning structure 150 and the protruding structure 420 completely overlap, all of which are embodiments of this embodiment. The plurality of positioning structures 150 and the plurality of protruding structures 420 may be arranged in a one-to-one correspondence, or the plurality of positioning structures 150 may be arranged in a corresponding manner with a portion of the plurality of protruding structures 420, which is not specifically limited herein.

[0159] Among them, the shape of the positioning structure 150 can be a protrusion set on the periphery of the frame body 100, or a recessed shape set on the periphery of the frame body 100, or a combination of the above two forms, or other structures and other multiple structures combined, which are not specifically limited here.

[0160] The technical solution of the present application adopts a method of providing a plurality of positioning structures 150 on the periphery of the frame body 100. The positioning structures 150 are aligned with the raised structures 420 on the outer periphery of the stator core 400, thereby facilitating the plug-in fit between the positioning portion 113 of the frame body 100 and the socket 730 on the stator core 400. This is a fool-proof design for operators assembling the stator assembly 10.

[0161] In one embodiment, referring to FIG. 14 to FIG. 18 , each of the protruding structures 420 is provided with a positioning hole 411 , and the positioning structure 150 is disposed corresponding to the positioning hole 411 .

[0162] Specifically, a positioning hole 411 is provided on the raised structure 420, and the positioning hole 411 is opposite to the positioning structure 150, so that the alignment effect of the positioning structure 150 and the positioning hole 411 is better, thereby making the alignment of the positioning portion 113 and the insertion hole 730 better. The shape of the positioning hole 411 can be circular, square, or irregular. In this embodiment, the positioning hole 411 provided on the raised structure 420 also has the function of assembling with other structures, specifically by pinning and installing, so the shape of the positioning hole 411 is set to be circular. It should be noted that the alignment of the positioning structure 150 and the positioning hole 411 is that when the positioning portion 113 is matched with the insertion hole 730, the positioning structure 150 is located near the positioning hole 411, or the positioning structure 150 and the positioning hole 411 partially overlap or the positioning structure 150 and the positioning hole 411 completely overlap. The above schemes are all schemes of this embodiment.

[0163] In one embodiment, referring to FIG. 14 to FIG. 18 , the positioning structure 150 is protrudingly disposed on the outer periphery of the frame body 100 .

[0164] It should be noted that, as can be seen from the figure, the positioning structure 150 protruding from the outer periphery of the frame body 100 can be as close to the positioning hole 411 as possible, making the alignment of the positioning structure 150 and the positioning hole 411 easier and the alignment effect better, thereby making it easier for the positioning part 113 to be inserted into the socket 730, facilitating the operation of the operator, and assembling the insulating frame 20 and the stator core 400 at one time.

[0165] Exemplarily, referring to FIG. 17 , the positioning structure 150 is provided with an opening 710 corresponding to the positioning hole 411 .

[0166] According to the above embodiment, the positioning structure 111 is further designed, and an opening 710 is opened at the position of the positioning structure 111 corresponding to the positioning hole 411, wherein the structure of the opening 710 corresponds to the structural setting of the positioning hole 411, so that the positioning structure 111 and the positioning hole 411 have a better alignment effect, making the assembly of the insulating frame 20 and the stator core 400 easier.

[0167] In one embodiment, referring to FIG. 17 , the positioning hole 411 is circular, and the groove wall of the notch groove 720 is arc-shaped corresponding to the positioning hole 411 .

[0168] Furthermore, since the positioning hole 411 is circular, the groove wall of the notch 720 is configured as an arc surface, making the notch 720 and the positioning hole 411 more accurately aligned and achieving a better alignment effect, thereby making it easier for the positioning portion 113 to mate with the insertion hole 730. Of course, the positioning hole 411 can also be square, and the notch 720 can also be configured to correspond to it in a square shape, and this solution is also within the scope of the above embodiment.

[0169] In one embodiment, referring to FIG. 17 , the opening 710 passes through opposite sides of the positioning structure 150 to form a notch 720 . The notch 720 has a notch 112 a facing away from the frame body 100 . The notch 112 a is disposed corresponding to the positioning hole 411 .

[0170] The notch groove 720 has a notch 112a that is away from the frame body 100. The notch 112a is set corresponding to the positioning hole 411. Specifically, the projection of the notch 112 on the protruding structure 420 is toward the positioning hole 411, so that the square shape of the notch 112a corresponds to the square shape of the positioning hole 411, thereby making the alignment of the notch groove 720 and the positioning hole 411 more precise, which is conducive to assembling the stator core 400 and the insulating frame 20 at one time.

[0171] In one embodiment, referring to Figures 14 and 18, the multiple protrusion structures 420 include two first protrusions 421 and one second protrusion 422, the distance between the two first protrusions 421 is smaller than the distance between any first protrusion 421 and the second protrusion 422, the number of the positioning structures 150 is set to two, and the two positioning structures 150 are respectively set corresponding to the two first protrusions 421.

[0172] It should be noted that in this embodiment, a total of three protrusion structures 420 are provided, two of which are first protrusions 421 and one is a second protrusion 422. The distance between the two first protrusions 421 is small, while the distance between the second protrusion 422 and any first protrusion 421 is large. Based on this, three positioning structures 150 can be provided to correspond to the three protrusion structures 420 respectively. However, considering that it is difficult for assemblers to visually determine the distance between the positioning structures 150, there is a possibility of initial installation errors.

[0173] In order to further strengthen the fool-proof design of the structure and enable the frame body 100 and the stator core 400 to be successfully assembled at one time, only two positioning structures 150 are provided corresponding to the two second protrusions 422 (the two protrusion structures 420 that are closer to each other can be more clearly distinguished from the figure). After the two positioning structures 150 are successfully aligned with the two protrusion structures 420, the socket 730 and the positioning portion 113 are also successfully aligned, which greatly saves assembly time and improves assembly efficiency.

[0174] In one embodiment, referring to FIG. 16 and FIG. 17 , the number of the positioning portions 113 is set to be multiple, the multiple positioning portions 113 are arranged at intervals on the frame body 100 , and the number of the insertion holes 730 is set to be multiple corresponding to the multiple positioning portions 113 .

[0175] Specifically, in order to further strengthen the limiting relationship between the frame body 100 and the stator core 400 and prevent the frame body 100 from rotating relative to the stator core 400, multiple jacks 730 and positioning portions 113 are respectively provided, and the two correspond one to one, further strengthening the limiting relationship between the frame body 100 and the stator core 400.

[0176] In one embodiment, referring to FIG. 14 , FIG. 16 and FIG. 18 , the insulating frame 20 further includes a welding platform 200 connected to the frame body 100 , and the welding platform 200 is located between two adjacent protruding structures 420 .

[0177] It should be noted that the insulating frame 20 not only includes a frame body 100, but also includes a welding table 200 for connecting the wire bundle wound out of the winding 500 to the welding wire terminal 300, and the welding table 200 is located between two adjacent protrusion structures 420, and the welding table 200 is spaced apart from the protrusion structure 420 in the axial direction, and the wall surface interferes with the stator core 400 during the welding process.

[0178] The wiring harness leading from the stator windings of existing motors is typically connected to terminals to facilitate electrical connection to other control modules. Laser welding offers several advantages, including high automation and production efficiency, while also avoiding the quality issues associated with piercing terminals.

[0179] Diffuse reflection often occurs during laser welding, and the reflected light formed by diffuse reflection of the laser also has a high temperature. The insulating frame used to install the terminal may cause its temperature to rise due to the long-term accumulation of reflected light, eventually causing risk accidents such as fire.

[0180] In view of this, the present application proposes a stator assembly 10 .

[0181] In the embodiment of the present application, as shown in Figures 19 to 23, the stator assembly 10 includes a stator core 400, an insulating frame 20 and a welding terminal 300. The insulating frame 20 is mounted on the stator core 400. The insulating frame 20 includes a frame body 100 and a welding platform 200 connected thereto. The welding platform 200 has a first surface 230, and a mounting platform 231 is provided on the first surface 230. The mounting platform 231 has a slot 810. The welding terminal 300 includes a plug-in portion connected thereto. 310 and a welding portion 320, the plug-in portion 310 is inserted into the slot 810, and the welding portion 320 is located on one side of the mounting platform 231; wherein, the mounting platform 231 includes a first stage 231b and a second stage 231c connected to each other, and the welding portion 320 is arranged on the welding platform 200 and is located on one side of the first stage 231b, and the height of the first stage 231b relative to the first surface 230 is less than the height of the second stage 231c relative to the first surface 230.

[0182] Specifically, the stator assembly 10 primarily consists of a stator core 400 and an insulating frame 20 mounted on the stator core 400. After the stator core 400 and insulating frame 20 are assembled, a winding 500 is wound around the stator core 400 and insulating frame 20. The stator core 400 has a plurality of stator teeth formed as protrusions toward its interior, while the insulating frame 20 is provided with a plurality of tooth portions corresponding to the plurality of stator teeth. The plurality of tooth portions corresponds one-to-one with the plurality of stator teeth. A winding 500 is wound around each stator tooth and tooth portion.

[0183] The welding platform 200 is part of the insulating frame 20 and serves as the location for welding the wire terminals 300 to the wire harness leading from the winding 500. The wire terminals 300 are mounted on the welding platform 200. To secure the wire terminals 300 and define their relative position, a mounting platform 231 is provided on the first surface 230 of the welding platform 200. Furthermore, to better secure the wire terminals 300, a slot 810 is provided on the mounting platform 231. The wire terminals 300 are inserted into the slot 810 to secure their relative position. The wire terminals 300 include a connecting portion 310 and a welding portion 320, which are connected to each other. In this embodiment, the welding portion 320 and the connecting portion 310 are integrally molded. The inserting portion 310 of the welding wire terminal 300 is inserted into the slot 810 so that the welding wire terminal 300 is fixed to the mounting platform 231 . The welding portion 320 is provided on one side of the mounting platform 231 for welding with the wire harness led out of the winding 500 .

[0184] Considering that during laser welding at the welding portion 320, the laser may diffusely reflect, potentially causing the mounting platform 231 adjacent to the welding portion 320 to heat up or even catch fire, a design to avoid the laser beam is implemented for the mounting platform 231. The mounting platform 231 is configured as a first stage 231b and a second stage 231c that are connected, with the welding section of the wire terminal 300 located to one side of the first stage 231b. Therefore, the design to avoid the laser beam is implemented for the first stage 231b, ensuring that its height relative to the first surface 230 is less than the height of the second stage 231c relative to the first surface 230. This lowering of the first stage 231b reduces the possibility of fire on the mounting platform 231, thereby improving safety during the laser welding process.

[0185] It should be noted that the slot 810 can be located on the first stage 231b, the second stage 231c, or both the first stage 231b and the second stage 231c, all of which are solutions of this embodiment. Furthermore, the first stage 231b can be partially or entirely disposed on the first surface 230, while the second stage 231c can be partially or entirely disposed on the first surface 230, without specific limitation herein.

[0186] The technical solution of the present application adopts an avoidance design for the mounting platform 231 for mounting the welding wire terminal 300 to form a first platform stage 231b and a second platform stage 231c, and makes the height of the first platform stage 231b smaller than the height of the second platform stage 231c, thereby preventing the mounting platform 231 from catching fire due to diffuse reflection of laser during laser welding, thereby improving the safety of the wiring harness of the welding wire terminal 300 and the winding 500 during laser automatic welding.

[0187] Further, referring to FIG. 19 and FIG. 20 , the height of the first stage 231 b relative to the first surface 230 is H, and H satisfies 0.3 mm ≤ H ≤ 0.6 mm.

[0188] According to the above embodiment, the height of the first stage 231b relative to the first surface 230 should not be too high, as this could cause the first stage 231b to catch fire, posing a safety hazard. Therefore, the height of the first stage 231b relative to the first surface 230 is set to be less than or equal to 0.6 mm. Furthermore, since the first stage 231b needs to secure the wire bonding terminal 300, the height of the first stage 231b relative to the first surface 230 is set to be equal to or greater than 0.3 mm. Therefore, the height of the first stage 231b can be any value within the range of 0.3 mm to 0.6 mm.

[0189] In one embodiment, referring to FIG. 20 and FIG. 21 , the welding platform 200 further has a second surface 820 . The second surface 820 is lower than the first surface 230 , and the second stage 231 c is partially disposed on the second surface 820 .

[0190] Specifically, the welding stage 200 further includes a second surface 820 that is height-differenced from the first surface 230. As described in the above embodiment, the second stage 231c is disposed on the first surface 230. Specifically, a portion of the second stage 231c is disposed on the first surface 230, while another portion of the second stage 231c is disposed on the second surface 820. Furthermore, the second surface 820 must be lower than the first surface 230. This arrangement allows the slot 810 on the second stage 231c to be deeper, thereby enhancing the securing and position-limiting effects of the second stage 231c on the welding wire terminal 300.

[0191] In one embodiment, referring to FIG. 21 , the slot 810 includes a first slot portion 221 a and a second slot portion 221 b , wherein the first slot portion 221 a is opened at the first stage 231 b , and the second slot portion 221 b is opened at the second stage 231 c , and the first slot portion 221 a is connected to the second slot portion 221 b .

[0192] It should be noted that the slot 810 includes two slot portions, namely the first slot portion 221a and the second slot portion 221b. The two slot portions are respectively opened on the first stage 231b and the second stage 231c, and the two slot portions are interconnected, which can better limit and fix the limiting terminal.

[0193] Please refer to FIG. 21 . The first stage 231 b is provided with an escape opening 222 a for evading the bonding wire terminal 300 .

[0194] Furthermore, considering that the welding wire terminal 300 is arranged on one side of the first stage 231b, it can be imagined that the welding wire terminal 300 has a portion that transitions from the slot 810 to one side of the first stage 231b. In order to better fix the welding wire terminal 300 on the welding stage 200, an avoidance opening 222a is opened on the first stage 231b to avoid the portion of the welding wire terminal 300 from the first groove portion 221a to the outside of the first stage 231b.

[0195] In one embodiment, referring to FIG. 20 and FIG. 21 , the first groove portion 221 a and the second groove portion 221 b are arranged on the same straight line.

[0196] It should be noted that, considering that the plug-in portion 310 of the welding wire terminal 300 is arranged in a sheet shape, the first groove portion 221a and the second groove portion 221a are arranged on the same straight line. Specifically, the groove widths of the first groove portion 221a and the second groove portion 221b are consistent and the first groove portion 221a and the second groove portion 221b are arranged in a aligned manner, so that the groove edges of the first groove portion 221a and the second groove portion 221b are arranged relative to each other, so that the slot 810 can better fix and limit the welding wire terminal 300.

[0197] In one embodiment, referring to FIG. 20 and FIG. 22 , the plug-in portion 310 has an extension section 321 exposed from the notch of the second slot portion 221 b , and the extension section 321 is used to connect with other components.

[0198] Specifically, the plug-in portion 310 has an extension section 321 that exposes the notch of the second slot portion 221b. According to the above embodiment, the welding portion 320 of the welding wire terminal 300 is used to weld the wire harness led out of the winding 500 wound on the stator core 400, and other components are electrically connected to the extension section 321 formed by the plug-in portion 310, wherein the electrical connection method can be welding or connection through other methods.

[0199] In one embodiment, referring to FIG. 20 and FIG. 22 , the inserting portion 310 and the welding portion 320 are perpendicular to each other.

[0200] It should be noted that the plug-in portion 310 and the welding portion 320 are perpendicular to each other, so that the structure can be partially inserted into the slot 810, and the other part is placed on one side of the first stage 231b, and the plug-in portion 310 and the welding portion 320 are integrally formed in a molten state, and the molding process is simple.

[0201] In one embodiment, referring to FIG. 19 to FIG. 21 , the insulating frame 20 is integrally formed in a mold.

[0202] Specifically, the insulating frame 20 is made of plastic material. The insulating frame 20 is integrally formed by injection molding in a mold, and some details are formed by processing after molding. This can save time and cost in making the insulating frame 20 and improve the efficiency of making the insulating frame 20.
