Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a stator lead-out structure, a stator, a motor, and a vehicle. Background Technology

[0002] The stator's lead-out structure refers to the part of the motor's internal stator windings that connects to the external power supply. The design of the stator's lead-out structure has a significant impact on the motor's performance, ease of installation, and ease of maintenance.

[0003] In related technologies, some stator output structures only have AC leads for inputting AC power to the stator. However, with the development of motor technology, motors have the need for self-heating or boost charging. When the motor is self-heating or boost charging, the stator needs to input DC power. The existing stator output structures cannot meet the needs of the motor. Although some stator output structures have DC leads, the structural design and layout of the DC and AC leads are unreasonable, resulting in poor reliability. Utility Model Content

[0043] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0044] The following is for reference. Figures 1-8 The present invention describes a stator 1000 with a lead-out structure 100 according to an embodiment of the present invention. The stator 1000 with a lead-out structure 100 can be applied to the stator 1000, the stator 1000 can be applied to a motor, and the motor can be applied to a vehicle.

[0045] Combination Figures 1-8 As shown, the stator 100 of this utility model has a lead-out structure 100 that mainly includes: AC lead-out wire 10 and DC lead-out wire 20.

[0046] The AC lead-out line 10 is adapted to be electrically connected to the stator 1000. The AC lead-out line 10 has an AC terminal 101, which is adapted to be electrically connected to an external AC power source. Specifically, one end of the AC lead-out line 10 is electrically connected to the stator 1000, and the other end is electrically connected to an external AC power source through the AC terminal 101. This allows for electrical connection between the stator 1000 and the external AC power source, ensuring normal motor operation. It should be noted that the motor's three-phase terminals are adapted to be electrically connected to an external AC power source. The AC lead-out line 10 is mainly used to achieve electrical connection between the three-phase terminals, the stator 1000, and the external AC power source. In this invention, there are three AC lead-out lines 10, each corresponding to a different phase.

[0047] Furthermore, the DC lead 20 is adapted to be electrically connected to the stator 1000. The DC lead 20 has a DC terminal 201, which is adapted to be electrically connected to an external DC power source. Specifically, one end of the DC lead 20 is electrically connected to the stator 1000, and the other end is electrically connected to an external DC power source via the DC terminal 201. This allows for electrical connection between the stator 1000 and the external DC power source through the DC lead 20, ensuring the normal operating performance of the motor. It should be noted that during self-heating and boost charging conditions, the motor's neutral (N) terminal is adapted to be electrically connected to an external DC power source. The DC lead 20 is mainly used to achieve electrical connection between the neutral terminal and the stator 1000 and the external DC power source.

[0048] This configuration allows AC power to be input to the stator 1000 via AC lead-out line 10, and DC power to be input to the stator 1000 via DC lead-out line 20 during self-heating and boost charging conditions. This improves the reliability of the stator 1000 structure and enhances its performance.

[0049] Furthermore, the DC terminals 201 and AC terminals 101 are arranged sequentially at intervals along the axial direction of the stator 1000. This not only optimizes the layout of the outgoing line structure 100, making it more regular and safe, but also prevents the risk of short circuit between the AC lead-out line 10 and the DC lead-out line 20 due to accidental contact or other reasons. At the same time, it also prevents mutual interference between the AC signal in the AC lead-out line 10 and the DC signal in the DC lead-out line 20, ensuring that both the AC signal in the AC lead-out line 10 and the DC signal in the DC lead-out line 20 can be transmitted stably, thus guaranteeing the normal operation of the stator 1000.

[0050] Therefore, by adapting the AC terminal 101 of the AC lead-out line 10 to be electrically connected to an external AC power source, adapting the DC terminal 201 of the DC lead-out line 20 to be electrically connected to an external DC power source, and electrically connecting both the AC lead-out line 10 and the DC lead-out line 20 to the stator 1000, AC power can be input to the stator 1000 not only through the AC lead-out line 10, but also through the DC lead-out line 20 during self-heating and boost charging conditions.

[0051] In a specific embodiment of this utility model, the alternating current can be three-phase alternating current.

[0052] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the AC lead-out line 10 also includes an AC main body section 102, and the AC terminal 101 is connected to the AC main body section 102. The DC lead-out line 20 also includes a DC main body section 202, and the DC terminal 201 is connected to the DC main body section 202. Both the AC main body section 102 and the DC main body section 202 are arc-shaped and are both suitable for electrical connection with the stator 1000 of the motor. The AC main body section 102 and the DC main body section 202 are spaced apart along the axial direction of the stator 1000.

[0053] Specifically, the stator 1000 in this utility model is annular. By making both the AC main body section 102 and the DC main body section 202 arc-shaped, it not only facilitates the electrical connection operation between the AC lead-out line 10 and the DC lead-out line 20 and the stator 1000, but also makes the connection between the AC lead-out line 10 and the DC lead-out line 20 and the stator 1000 more stable and reliable.

[0054] Furthermore, AC terminal 101 is connected to AC main body section 102, and DC terminal 201 is connected to DC main body section 202. Both AC main body section 102 and DC main body section 202 are suitable for electrical connection with stator 1000. This ensures that external AC and DC power can be transmitted normally to stator 1000, thus ensuring the normal operation of stator 1000.

[0055] Furthermore, the AC main section 102 and the DC main section 202 are spaced apart along the axial direction of the stator 1000. This not only prevents the risk of short circuits caused by accidental contact or other reasons between the AC main section 102 and the DC main section 202, but also prevents mutual interference between the AC signal in the AC main section 102 and the DC signal in the DC main section 202. This ensures that both AC and DC signals can be transmitted stably, guarantees the normal operation of the stator 1000, and optimizes the layout of the stator 100's outgoing line structure 100.

[0056] Combination Figure 1 , Figure 3 and Figure 6 As shown, the AC lead-out line 10 further includes an AC connection section 103, which extends axially in the stator 1000. One axial end of the AC connection section 103 is connected to the AC main body section 102, and the AC terminal 101 extends radially in the stator 1000 and is connected to the other axial end of the AC connection section 103; and / or the DC lead-out line 20 further includes a DC connection section 203, which extends axially in the stator 1000. One axial end of the DC connection section 203 is connected to the DC main body section 202, and the DC terminal 201 extends radially in the stator 1000 and is connected to the other axial end of the DC connection section 203.

[0057] Specifically, the AC connection section 103 extends axially in the stator 1000 and is located between the AC main body section 102 and the AC terminal 101. External DC power is transmitted to the stator 1000 through the DC terminal 201, the AC connection section 103, and the AC main body section 102. This not only ensures a complete electrical connection path between the external AC power and the stator 1000, but also makes the layout of the AC power lead-out line 10 more regular and optimizes the lead-out structure 100 of the stator 1000.

[0058] Furthermore, the DC connection section 203 extends axially in the stator 1000 and is disposed between the DC main body section 202 and the DC terminal 201. External DC power is transmitted to the stator 1000 through the DC terminal 201, the DC connection section 203, and the DC main body section 202. This not only ensures a complete electrical connection path between the external DC power and the stator 1000, but also makes the layout of the DC lead wire 20 more regular and optimizes the outgoing wire structure 100 of the stator 1000.

[0059] Combination Figure 1 , Figure 3 and Figure 6 As shown, the AC connection section 103 includes a first AC connection section 1031 and a second AC connection section 1032. The first AC connection section 1031 extends axially in the stator 1000 and its two ends are respectively connected to the AC main body section 102 and the second AC connection section 1032. The second AC connection section 1032 extends radially in the stator 1000 and is connected to the AC terminal 101. And / or the DC connection section 203 includes a first DC connection section 2031 and a second DC connection section 2032. The first DC connection section 2031 extends axially in the stator 1000 and its two ends are respectively connected to the DC main body section 202 and the second DC connection section 2032. The second DC connection section 2032 extends radially in the stator 1000 and is connected to the DC terminal 201.

[0060] Specifically, the first AC connection section 1031 extends axially in the stator 1000. The two ends of the first AC connection section 1031 are connected to the AC main body section 102 and the second AC connection section 1032, respectively. The second AC connection section 1032 extends radially in the stator 1000, and the AC terminal 101 also extends radially in the stator 1000. The end of the second AC connection section 1032 away from the first AC connection section 1031 is connected to the AC terminal 101. This facilitates the electrical connection between the AC main body section 102 and the AC connection section 103, as well as the electrical connection between the AC connection section 103 and the AC terminal 101. It also forms a stable and effective electrical connection path between the AC main body section 102 and the AC terminal 101 to ensure the normal working performance of the stator 1000. In addition, it makes the layout of the AC lead wires 10 more regular and optimizes the outgoing wire structure 100 of the stator 1000.

[0061] Furthermore, the first DC connection segment 2031 extends axially in the stator 1000, and its two ends are connected to the DC main body segment 202 and the second DC connection segment 2032, respectively. The second DC connection segment 2032 extends radially in the stator 1000, and the DC terminal 201 also extends radially in the stator 1000. The end of the second DC connection segment 2032 away from the first DC connection segment 2031 is connected to the DC terminal 201. This facilitates the electrical connection between the DC main body segment 202 and the DC connection segment 203, as well as the electrical connection between the DC connection segment 203 and the DC terminal 201. It also forms a stable and effective electrical connection path between the DC main body segment 202 and the DC terminal 201 to ensure the normal working performance of the stator 1000. In addition, it makes the layout of the DC lead wires 20 more regular and optimizes the outgoing wire structure 100 of the stator 1000.

[0062] Combination Figure 1 , Figure 3 and Figure 6 As shown, the first AC connection segment 1031 and the first DC connection segment 2031 are spaced apart radially in the stator 1000, and the second AC connection segment 1032 and the second DC connection segment 2032 are spaced apart axially in the stator 1000. Specifically, both the first AC connection segment 1031 and the first DC connection segment 2031 extend axially in the stator 1000 and are spaced apart radially in the stator 1000. Similarly, both the second AC connection segment 1032 and the second DC connection segment 2032 extend radially in the stator 1000 and are spaced apart axially in the stator 1000. This arrangement not only avoids the AC connection segment 1031 and the first DC connection segment 2031 being separated in the stator 1000, but also prevents the AC connection segment 1031 and the first DC connection segment 2032 from being separated in the stator 1000. The DC connection sections 203 are protected from the risk of short circuits caused by accidental contact or other reasons. They also prevent mutual interference between AC signals in AC connection section 103 and DC signals in DC connection section 203, ensuring stable transmission of both AC signals in AC connection section 103 and DC signals in DC connection section 203. This guarantees the normal operation of stator 1000 and makes the stator 1000's outgoing wire structure 100 more regular and safe, facilitating maintenance and repair of the stator 1000's outgoing wire structure 100.

[0063] Combination Figure 1 , Figure 4 and Figure 5 As shown, the stator 100's outgoing wire structure 100 also includes a first injection molded part 301. The first injection molded part 301 is wrapped around the outside of the AC connection section 103 and the DC connection section 203. The AC connection section 103 extends at least partially from the first injection molded part 301 and is connected to the AC terminal 101. The DC connection section 203 extends at least partially from the first injection molded part 301 and is connected to the DC terminal 201.

[0064] Specifically, the first injection molded part 301 is wrapped around the outside of the AC connection section 103 and the DC connection section 203. The first injection molded part 301 can fix the wrapped parts of the AC connection section 103 and the DC connection section 203 and reduce positional errors. Furthermore, the first injection molded part 301 is an insulating structure, which can meet the electrical insulation requirements of the motor under the high voltage platform. It can improve the electrical insulation performance of the AC connection section 103 and the DC connection section 203 wrapped by the first injection molded part 301. At the same time, it can also reduce the electrical insulation requirements of the AC connection section 103 and the DC connection section 203 wrapped by the first injection molded part 301 and increase the design margin.

[0065] Furthermore, by applying enameling and plastic coating to the AC connection section 103 and DC connection section 203, the portions of the AC connection section 103 and DC connection section 203 encased in the first injection molded part 301 can achieve double insulation, thereby significantly improving their electrical insulation performance. Enameling refers to coating the surfaces of the AC lead-out wire 10 and DC lead-out wire 20 with an insulating varnish, while plastic coating refers to the encasing effect of the first injection molded part 301; enameling is applied first, followed by plastic coating.

[0066] Furthermore, the AC connection segment 103 extends at least partially from the first injection molded part 301 and is connected to the AC terminal 101, and the DC connection segment 203 extends at least partially from the first injection molded part 301 and is connected to the DC terminal 201. This facilitates the electrical connection of the AC connection segment 103 to the AC terminal 101 and the DC connection segment 203 to the DC terminal 201, preventing difficulties in connecting the AC connection segment 103 to the AC terminal 101 and the DC connection segment 203 to the DC terminal 201 due to the enclosure of the first injection molded part 301.

[0067] In addition, reinforcing ribs can be added to the first injection molded part 301, which can not only effectively improve the strength of the first injection molded part 301, but also reduce the positioning difficulty during injection molding. At the same time, using different phases to create holes can achieve effective weight reduction.

[0068] Combination Figure 1 , Figure 3 and Figure 5 As shown, the first injection molded part 301 covers at least a portion of the AC main body section 102 adjacent to the AC connection section 103, and the first injection molded part 301 covers at least a portion of the DC main body section 202 adjacent to the DC connection section 203. Specifically, by encasing at least a portion of the AC main body segment 102 adjacent to the AC connection segment 103 and at least a portion of the DC main body segment 202 adjacent to the DC connection segment 203 with the first injection molded part 301, the connection points of the AC main body segment 102 and the AC connection segment 103, as well as the connection points of the DC main body segment 202 and the DC connection segment 203, can be fixed. This makes the connection between the AC main body segment 102 and the AC connection segment 103, and the connection between the DC main body segment 202 and the DC connection segment 203 more stable and reliable, preventing connection failures or poor contact at the connection points of the AC main body segment 102 and the AC connection segment 103, and the connection points of the DC main body segment 202 and the DC connection segment 203. This ensures that AC signals can be stably transmitted between the AC main body segment 102 and the AC connection segment 103, and that DC signals can be stably transmitted between the DC main body segment 202 and the DC connection segment 203.

[0069] In some embodiments of this utility model, the DC main body segment 202 contacts the first injection molded part 301 to form two injection molded ends 303.

[0070] In some embodiments of this utility model, the AC lead 10 and the DC lead 20 can be integrated into one assembly through the first injection molded part 301. The first injection molded part 301 contacts the iron core of the stator 1000 welding end in the axial direction, which can effectively reduce the axial position error. At the same time, since the first injection molded part 301 is an insulating structure, the part of the DC lead 20 and the AC lead 10 inside the first injection molded part 301 can effectively increase the electrical insulation performance, reduce the electrical insulation requirements of this part, and increase the design margin.

[0071] Combination Figure 2 , Figure 3 and Figure 6 As shown, the DC main body section 202 includes a first DC main body section 2021 and a second DC main body section 2022. The first DC main body section 2021 and the second DC main body section 2022 are arranged opposite to each other. One end of the first DC main body section 2021 and one end of the second DC main body section 2022 are spaced apart from each other and are both connected to the DC connection section 203. Specifically, since the current input from the DC lead 20 is DC in both the self-heating and boost charging modes, the first DC main body section 2021 and the second DC main body section 2022 can be segmented to divert the current into the windings of the stator 1000 during boost charging and self-heating modes. At this time, the DC current passing through the first DC main body section 2021 and the second DC main body section 2022 is 4 / 9 and 5 / 9 of the DC current passing through a single DC main body section 202, respectively. When designing the thickness of the first DC main body section 2021 and the second DC main body section 2022 according to the electrical density design, the thickness of the first DC main body section 2021 and the second DC main body section 2022 can be reduced, thereby effectively reducing the overall axial height of the stator 1000.

[0072] Combination Figure 6 , Figure 7 and Figure 8 As shown, the DC connection section 203 and the DC main body section 202 are connected by welding. Different welding methods can be adopted depending on the extension direction of the DC connection section 203, the welding direction of the welding end of the DC main body section 202 and the number of welding.

[0073] Specifically, the length of the first DC connection segment 2031 extends in the axial direction of the stator 1000, and the extension direction of the width of the first DC segment is parallel or perpendicular to the radial extension direction of the second DC connection segment 2032. This not only improves the structural strength of the first DC segment, but also ensures the normal transmission of DC signals within the first DC segment.

[0074] Furthermore, the DC connection section 203 is connected to the DC main body section 202 by welding. The DC main body section 202 is composed of a first DC main body section 2021 and a second DC main body section 2022. When the welding surfaces of the first DC main body segment 2021 and the DC connection segment 203 are not in the same direction, two welding operations are required to connect and fix the first DC main body segment 2021 and the second DC main body segment 2022 to the DC connection segment 203, thereby achieving electrical connection between the DC main body segment 202 and the DC connection segment 203. When the welding surfaces of the first DC main body segment 2021 and the DC connection segment 203 are in the same direction, only one welding operation is required to connect and fix the first DC main body segment 2021 and the second DC main body segment 2022 to the DC connection segment 203, thereby achieving electrical connection between the DC main body segment 202 and the DC connection segment 203.

[0075] It should be noted that, Figure 6 , Figure 7 and Figure 8 The content shown does not reflect the differences of the first injection molded part 301.

[0076] In some embodiments of this utility model, the DC main body section 202 and the DC connection section 203 can be welded by resistance welding.

[0077] Combination Figure 2 , Figure 3 and Figure 5 As shown, the AC main body section 102 is provided with a plurality of AC power connection parts 1021, which are arranged circumferentially on the AC main body section 102; and / or the DC main body section 202 is provided with a plurality of DC power connection parts 2023, which are arranged circumferentially on the DC main body section 202.

[0078] Specifically, the AC main body section 102 and the stator 1000 can be electrically connected through the AC connection part 1021. The multiple AC connection parts 1021 are arranged circumferentially on the AC main body section 102. This not only avoids short circuits between different phases, but also reduces magnetic field coupling and improves the anti-interference capability of the AC signal transmission line. At the same time, the circumferentially spaced AC connection parts 1021 layout can also help air circulation, improve the heat dissipation of the motor, facilitate the installation, maintenance and repair of the AC main body section 102 and the stator 1000, and improve the stability of the motor structure.

[0079] Furthermore, the DC connection part 2023 enables electrical connection between the DC main body section 202 and the stator 1000. By circumferentially spacing multiple DC connection parts 2023 on the DC main body section 202, not only can magnetic field coupling be reduced and the anti-interference capability of the DC signal transmission line be improved, but the circumferentially spaced DC connection parts 2023 layout can also facilitate air circulation, improve the heat dissipation of the motor, facilitate the installation, maintenance and repair of the DC main body section 202 and the stator 1000, and improve the stability of the motor structure.

[0080] Combination Figure 2 , Figure 3 and Figure 5 As shown, the projections of the AC connection part 1021 and the DC connection part 2023 on the axial direction of the stator 1000 are offset from each other. Specifically, the AC connection part 1021 is disposed on the AC main body section 102, and the DC connection part 2023 is disposed on the DC main body section 202. The AC main body section 102 and the DC main body section 202 are spaced apart in the axial direction of the stator 1000. The projections of the AC connection part 1021 and the DC connection part 2023 in the axial direction of the stator 1000 are also staggered. This not only prevents the risk of short circuit caused by accidental contact or other reasons between the AC main body section 102 and the DC main body section 202, but also prevents mutual interference between the AC signal in the AC main body section 102 and the DC signal in the DC main body section 202. This ensures that the AC signal in the AC main body section 102 and the DC signal in the DC main body section 202 can be stably transmitted to the stator 1000, guaranteeing the normal operation of the stator 1000 and optimizing the layout of the stator 100's outgoing line structure 100.

[0081] Combination Figure 2 , Figure 3 and Figure 5 As shown, the AC connection 1021 and / or the DC connection 2023 are welded electrical connections. Specifically, the welded electrical connections not only have good conductivity but also sufficient mechanical strength and durability. By making the AC connection 1021 and / or the DC connection 2023 welded electrical connections, the reliability of the electrical connection between the AC main body section 102 and the stator 1000, and between the DC main body section 202 and the stator 1000, is ensured, guaranteeing the normal transmission of AC and DC signals. Furthermore, the mechanical strength of the connection between the AC main body section 102 and the stator 1000, and between the DC main body section 202 and the stator 1000, is improved, preventing loosening or breakage at the connection points.

[0082] Combination Figure 2 , Figure 3 and Figure 5As shown, a second injection-molded part 302 is provided on the AC main body section 102 and / or the DC main body section 202, and the second injection-molded part 302 is adapted to be positioned and engaged with the stator 1000. Specifically, by providing the second injection-molded part 302 on the AC main body section 102 and / or the DC main body section 202, and by providing the second injection-molded part 302 to be positioned and engaged with the stator 1000, it not only serves to fix the AC main body section 102 and / or the DC main body section 202, but also improves the convenience and accuracy of the connection between the stator 1000 and the AC main body section 102 and / or the DC main body section 202, and enhances the stability and reliability of the connection between the stator 1000 and the AC main body section 102 and / or the DC main body section 202. At the same time, since the second injection-molded part 302 is an insulating material, it can also effectively improve the electrical insulation performance of the AC main body section 102 and / or the DC main body section 202, and reduce the electrical clearance requirements of the AC main body section 102 and / or the DC main body section 202.

[0083] Combination Figure 2 , Figure 3 and Figure 5 As shown, a second injection-molded part 302 is provided on the AC main body section 102, and an AC connection part 1021 is provided on the second injection-molded part 302; and / or a second injection-molded part 302 is provided on the DC main body section 202, and a DC connection part 2023 is provided on the second injection-molded part 302. Specifically, the second injection-molded part 302 has insulating properties, and the AC connection part 1021 and / or the DC connection part 2023 has conductive properties. By providing the second injection-molded part 302 on the AC main body section 102 and / or the DC main body section 202, and providing the AC connection part 1021 on the second injection-molded part 302 on the AC main body section 102, and / or providing the DC connection part 2023 on the second injection-molded part 302 on the DC main body section 202, this not only serves to fix the AC main body section 102 and / or the DC main body section 202, but also enhances the AC connection part. The stability of 1021 and / or DC connection 2023 ensures that an electrical connection path can be formed between AC main section 102 and / or DC main section 202 and stator 1000. AC main section 102 and / or DC main section 202 can be electrically connected to stator 1000 through electrical connection parts on their respective structures, thereby ensuring that AC signals can be stably transmitted between AC main section 102 and stator 1000, and / or DC signals can be stably transmitted between DC main section 202 and stator 1000, so as to ensure the normal working performance of stator 1000.

[0084] In some embodiments of this utility model, the AC connection part 1021 and / or the DC connection part 2023 are welded to the stator 1000 by argon arc welding.

[0085] Combination Figure 1 , Figure 4 and Figure 5 As shown, the DC terminal 201 and / or AC terminal 101 are provided with electrical connection holes 40 for connection and fixation with the terminal block 50. Specifically, by providing electrical connection holes 40 on the DC terminal 201 and / or AC terminal 101 for connection and fixation with the terminal block 50, the electrical connection holes 40 can provide a reliable interface, allowing external DC power to be stably transmitted from the terminal block 50 to the DC terminal 201, and / or allowing external AC power to be stably transmitted from the terminal block 50 to the AC terminal 101. This not only ensures stable current transmission between the terminal block 50 and the DC terminal 201 and / or AC terminal 101, but also facilitates the electrical connection operation between the terminal block 50 and the DC terminal 201 and / or AC terminal 101, making it easier to replace or repair the terminal block 50 and the outgoing wiring structure 100 of the stator 1000.

[0086] Furthermore, the DC terminal 201 and AC terminal 101 are electrically connected to the terminal block 50, which can accept AC power input from the electronic control side through the terminal block 50 or DC power input under self-heating and boost charging conditions, thereby inputting these AC or DC powers into the stator 1000 to ensure the normal operation of the stator 1000.

[0087] In some embodiments of this utility model, the electrical connection holes 40 on the DC terminal 201 and / or AC terminal 101 are connected to the terminal block 50 by bolts.

[0088] Combination Figure 1 , Figure 4 and Figure 5 As shown, DC terminal 201 and / or AC terminal 101 are flexible copper busbar terminals. Specifically, by making DC terminal 201 and / or AC terminal 101 flexible copper busbar terminals, the self-deformation capability of the flexible copper busbar makes it easier for DC terminal 201 and / or AC terminal 101 to deform in response to positional errors. This not only effectively reduces radial positional errors caused by assembly, but also provides a low-resistance electrical connection at DC terminal 201 and / or AC terminal 101, reducing energy loss and heat generation.

[0089] Combination Figure 1 and Figure 2 As shown, the stator 1000 according to this utility model can mainly include: the above-mentioned stator 1000 lead-out structure 100; and the stator body 200, wherein the lead-out structure 100 is electrically connected to the stator body 200.

[0090] Specifically, one end of the outgoing line structure 100 is electrically connected to the stator body 200, and the other end is electrically connected to the terminal block 50. This allows AC power to be input through the terminal block 50 or DC power to be input under self-heating and boost charging conditions. These AC or DC powers are then input into the stator 1000 through the outgoing line structure 100 to ensure the normal operation of the stator 1000.

[0091] Furthermore, since the outgoing line structure 100 of the stator 1000 is more reliable and has good working performance, applying the outgoing line structure 100 to the stator 1000 not only allows AC power to be input to the stator 1000 through the AC power lead 10, but also allows DC power to be input to the stator 1000 through the DC power lead 20 under self-heating and boost charging conditions.

[0092] The motor according to this utility model mainly includes the aforementioned stator 1000. Specifically, since the stator 1000 has a more reliable structure and good working performance, applying the stator 1000 to the motor can optimize the motor's structure and improve its working performance.

[0093] The vehicle according to this utility model can mainly include the aforementioned motor. Specifically, because the motor has a more reliable structure and good working performance, applying the motor to a vehicle can optimize the vehicle's performance and improve its reliability.
