[0079] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0080] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0081] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0082] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0083] The motor is the power device of the electric device. The motor is used to convert electrical energy into mechanical energy to drive the electric device. The motor usually includes a rotor and a stator. During the operation of the motor, the rotor rotates while the stator is fixed. In order to reduce the risk of interference between the rotor and the stator, a separator is usually set between the rotor and the stator to separate the rotor and the stator.

[0084] In the related art, the separator is usually made of insulating material, for example, the separator is made of plastic. Therefore, the structural strength of the separator is poor. During the operation of the motor, the separator is easily deformed toward the direction of the rotor under the action of other external forces. When the deformation amplitude of the separator is too large, the separator will contact the rotor, resulting in interference between the separator and the rotor. Especially when the rotor rotates at high speed, it is easy to cause damage to the inside of the motor, which is not conducive to improving the performance of the motor.

[0085] In order to reduce the risk of interference between the separator and the rotor, the stator of the motor provided in the embodiment of the present application is connected to the separator. Since the stator is fixed, the part where the separator is connected to the stator is also fixed, so that the position of the part where the separator is connected to the stator is relatively fixed with the position of the rotor. In this way, the deformation of the separator toward the rotor is effectively improved, thereby effectively reducing the risk of interference between the separator and the rotor, which is beneficial to improving the performance of the motor.

[0086] The motor provided in the embodiment of the present application can be applied to electric equipment, and the electric equipment can be but is not limited to vehicles, ships, airplanes, spacecraft, excavators, cranes, lifts, elevators, etc., and no specific limitation is made here.

[0087] For the convenience of description, the following embodiments are described by taking the electric device of one embodiment of the present application as a vehicle as an example.

[0088] See also Figure 1 , Figure 1 The schematic diagram of the structure of the vehicle 1000 provided in the embodiment of the present application. According to the power source, the vehicle 1000 can be a pure electric vehicle, a hybrid electric vehicle or an extended-range vehicle, etc. According to the driving mode, the vehicle 1000 can be a front-wheel drive vehicle, a rear-wheel drive vehicle or a four-wheel drive vehicle.

The vehicle body 200 has a cabin and a driving cabin, wherein the cabin is used to accommodate the power mechanism, electric control mechanism, transmission mechanism, etc. of the vehicle 1000, and the driving cabin is used to provide operating space and riding space for the driver and passengers. When the vehicle 1000 is a front-wheel drive vehicle, the cabin is arranged at the head of the vehicle body 200, that is, the cabin is the front cabin; when the vehicle 1000 is a rear-wheel drive vehicle, the cabin is arranged at the rear of the vehicle body 200, that is, the cabin is the rear cabin; when the vehicle 1000 is a four-wheel drive vehicle, the cabin is divided into a front cabin and a rear cabin, the front cabin is arranged at the head of the vehicle body 200, and the rear cabin is arranged at the rear of the vehicle body 200. The driving cabin is arranged between the head and the rear of the vehicle body 200.

[0090] The electric drive system 100 is a power system of the vehicle 1000, and is used to convert electrical energy into mechanical energy and output the mechanical energy to the wheels of the vehicle 1000 to drive the vehicle 1000. The electric drive system 100 is disposed on the vehicle body 200, and specifically, a part of the electric drive system 100 can be disposed in the cabin, and another part of the electric drive system 100 can be disposed at the bottom of the vehicle body 200.

[0091] See also Figure 1 , the electric drive system 100 provided in the embodiment of the present application includes a battery 20 and an electric drive device 10 .

[0092] The battery 20 is used to provide electric energy for the electric drive device 10. The battery 20 can be arranged at the bottom, head or tail of the vehicle 1000.

The second box body 212 may be a hollow structure with one end open, and the first box body 211 may be a plate-like structure, and the first box body 211 is covered on the open side of the second box body 212, so that the first box body 211 and the second box body 212 jointly define a storage space; the first box body 211 and the second box body 212 may also be hollow structures with one side open, and the open side of the first box body 211 is covered on the open side of the second box body 212. Of course, the battery box 21 formed by the first box body 211 and the second box body 212 can be in various shapes, such as a cylinder, a cuboid, etc.

[0093] In some embodiments, the battery box 21 may be a part of the chassis structure of the vehicle 1000. For example, a portion of the battery box 21 may become at least a portion of the floor of the vehicle 1000, or a portion of the battery box 21 may become at least a portion of the cross beam and longitudinal beam of the vehicle 1000.

[0094] Of course, in some embodiments, the battery 20 may not include a battery box 21 , but rather a plurality of battery cells 22 may be electrically connected and formed into a whole through necessary fixing structures and then assembled into the vehicle 1000 .

[0095] In the battery 20, there may be multiple battery cells 22, and the multiple battery cells 22 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 22 are both connected in series and in parallel. The multiple battery cells 22 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 22 is accommodated in the battery box 21. Of course, the battery 20 may also be a battery module formed by connecting multiple battery cells 22 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the battery box 21.

[0097] The electric drive device 10 is used to convert the electric energy provided by the battery 20 into mechanical energy and output the mechanical energy to the wheels of the vehicle 1000 to drive the vehicle 1000. The electric drive device 10 is installed in the cabin. Specifically, when the vehicle 1000 is a front-wheel drive vehicle, the electric drive device 10 is installed in the front cabin and is used to output the mechanical energy to the front wheels of the vehicle 1000 to drive the vehicle 1000; when the vehicle 1000 is a rear-wheel drive vehicle, the electric drive device 10 is installed in the rear cabin and is used to output the mechanical energy to the rear wheels of the vehicle 1000 to drive the vehicle 1000; when the vehicle 1000 is a four-wheel drive vehicle, there are two electric drive devices 10, one electric drive device 10 is installed in the front cabin and is used to output the mechanical energy to the front wheels of the vehicle 1000, and the other electric drive device 10 is installed in the rear cabin and is used to output the mechanical energy to the rear wheels of the vehicle 1000 to drive the vehicle 1000.

[0098] The electric drive device 10 includes a motor 11, which is the main power output component of the electric drive device 10 and is used to convert the electric energy provided by the battery 20 into mechanical energy. The electric drive device 10 may also include a speed change mechanism 12, which is the power transmission mechanism of the electric drive device 10. The speed change mechanism 12 has a power input end and a power output end. The power input end of the speed change mechanism 12 is connected to the rotating shaft of the motor 11, and the power output end of the speed change mechanism 12 is connected to the wheels of the vehicle 1000, so as to transfer the above mechanical energy to the wheels of the vehicle 1000 by changing the speed and torque of the motor 11. The electric drive device 10 may also include a controller 13, which is used to convert the direct current output by the battery 20 into alternating current and transmit the alternating current to the motor 11, and is also used to control the operation of the motor 11, for example, to control the start and stop, speed, torque, etc. of the motor 11.

[0099] The motor 11 provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0100] First, please also refer to Figure 5 and Figure 6 The embodiment of the present application provides a motor 11, including a first housing 111, a stator 112 and a rotor 113. The first housing 111 includes a housing body 1111 and a partition 1112, wherein the partition 1112 is disposed in the housing body 1111 to separate the interior of the housing body 1111 into a first accommodation space 1113 and a second accommodation space 1114. The stator 112 is accommodated in the first accommodation space 1113, and the stator 112 is connected to the partition 1112. The rotor 113 is accommodated in the second accommodation space 1114.

[0101] The first housing 111 is a component for providing an installation environment for the stator 112 and the rotor 113. In some embodiments, the first housing 111 may be an integrally formed component, for example, the housing body 1111 and the separator 1112 are integrally formed by an injection molding process. In other embodiments, the first housing 111 may be an assembled component assembled from a plurality of parts, for example, the housing body 1111 and the separator 1112 are independently formed and then connected together. In order to ensure the insulation performance of the motor 11, the first housing 111 may be made entirely of insulating materials, or the first housing 111 may be made of a composite of insulating materials and metal materials, for example, the inner layer structure of the housing body 1111 of the first housing 111 is made of metal material, and the surface structure of the housing body 1111 is made of insulating material, in other words, the insulating material is coated with the metal material. In order to reduce the magnetic resistance between the stator 112 and the rotor 113, the separator 1112 of the first housing 111 is made of insulating material. The insulating material may be, but is not limited to, plastic, rubber, insulating fiber, etc., and the metal material may be, but is not limited to, copper, iron, aluminum, stainless steel, aluminum alloy, etc.

[0102] The shell body 1111 is the main part of the first shell 111, which is used to define the above-mentioned installation environment. Among them, the first accommodation space 1113 and the second accommodation space 1114 are two parts of the installation environment provided by the shell body 1111. The first accommodation space 1113 is used to accommodate the stator 112, and the second accommodation space 1114 is used to accommodate the rotor 113.

[0103] The partition 1112 is a component used to separate the above-mentioned installation environment to form a first accommodating space 1113 and a second accommodating space 1114. In other words, the partition 1112 is arranged between the stator 112 and the rotor 113. It can be understood that the first accommodating space 1113 and the second accommodating space 1114 are separated from each other, that is, the components arranged in the first accommodating space 1113 cannot directly enter the second accommodating space 1114. For example, when the first accommodating space 1113 accommodates a cooling medium, the cooling medium cannot directly enter the second accommodating space 1114. Similarly, the components arranged in the second accommodating space 1114 cannot directly enter the first accommodating space 1113.

[0104] The rotor 113 is the rotating part of the motor 11. The stator 112 is the fixed part of the motor 11, and is used to drive the rotor 113 to rotate. It can be understood that the stator 112 and the rotor 113 are spaced to form an air gap, and the partition 1112 is arranged in the air gap.

[0105] In some embodiments, the motor 11 is an axial flux motor 11, the cross-section of the shell body 1111 along the direction perpendicular to the central axis of the motor 11 is roughly annular, the inner annular space of the shell body 1111 constitutes the above-mentioned installation environment, the partition 1112 is roughly plate-like and intersects with the central axis of the motor 11. For example, the partition 1112 is perpendicular to the central axis of the motor 11, and the partition 1112 separates the above-mentioned installation environment into a first accommodating space 1113 and a second accommodating space 1114. The first accommodating space 1113 and the second accommodating space 1114 are arranged along the axial direction of the motor 11, the stator 112 is arranged in the first accommodating space 1113, and the rotor 113 is arranged in the second accommodating space 1114.

[0106] In other embodiments, the motor 11 is a radial flux motor 11, the cross-section of the shell body 1111 along the direction perpendicular to the central axis of the motor 11 is roughly annular, the inner ring space of the shell body 1111 constitutes the above-mentioned installation environment, the partition 1112 along the direction perpendicular to the central axis of the motor 11 is roughly annular, the shell body 1111 is sleeved on the partition 1112, and the partition 1112 separates the above-mentioned installation environment into a first accommodating space 1113 and a second accommodating space 1114. For example, the outer peripheral space of the partition 1112 constitutes the first accommodating space 1113, and the inner ring space of the partition 1112 constitutes the second accommodating space 1114. For another example, the outer peripheral space of the partition 1112 constitutes the second accommodating space 1114, and the inner ring space of the partition 1112 constitutes the first accommodating space 1113. The stator 112 is arranged in the first accommodating space 1113, and the rotor 113 is arranged in the second accommodating space 1114.

[0107] The motor 11 provided in the embodiment of the present application is connected to the partition 1112 through the stator 112, so that the position of the part where the partition 1112 is connected to the stator 112 is relatively fixed with the position of the rotor 113. In this way, the deformation of the partition 1112 toward the rotor 113 is effectively improved, thereby effectively reducing the risk of interference between the partition 1112 and the rotor 113, which is beneficial to improving the performance of the motor 11.

[0108] In some embodiments of this application, please refer to Figures 7 to 11 The stator 112 includes a plurality of iron cores 1121 and a plurality of slot wedges 1122 . A winding slot 1123 is formed between two adjacent iron cores 1121 . The slot wedges 1122 are inserted into the winding slot 1123 and connected to the separator 1112 .

[0109] The core 1121 is the main part of the stator 112. The stator 112 may also include a winding, and the core 1121 is used to provide a space for placing the winding. The core 1121 and the winding together constitute the magnetic circuit of the motor 11. In some embodiments, the stator 112 also includes a base 1124, and a plurality of cores 1121 are arranged on the base 1124 and arranged around the central axis of the motor 11. Two adjacent cores 1121 are spaced apart to form a winding groove 1123, and the winding groove 1123 has a notch 11235, and the winding is placed in the winding groove 1123 through the notch 11235, and the notch 11235 is arranged opposite to the partition 1112. In some embodiments, the core 1121 can be an assembled component assembled from multiple components, for example, the core 1121 is formed by stacking multiple punching sheets in sequence. In other implementations, the core 1121 can also be an integrally formed component, for example, the core 1121 is integrally formed by a casting process.

[0110] The slot wedge 1122 is a component used to fix the winding. When the winding operation of the winding is completed, the slot wedge 1122 is inserted into the winding groove 1123 to block the notch 11235 of the winding groove 1123, thereby fixing the winding in the winding groove 1123. The slot wedge 1122 can be an integrally formed component, or an assembled component assembled from multiple parts, which is not specifically limited here. In this embodiment, the slot wedge 1122 also serves to insulate the core 1121 from the winding, that is, the slot wedge 1122 is made of insulating material. In order to improve the connection strength between the slot wedge 1122 and the separator 1112, the material of the slot wedge 1122 is the same as that of the separator 1112. For example, the material of the separator 1112 is plastic, and accordingly, the material of the slot wedge 1122 is also plastic.

[0111] By adopting the above technical solution, a slot wedge 1122 of corresponding material can be selected according to the material of the partition 1112, so that the material of the slot wedge 1122 is the same as that of the partition 1112, or the material type of the slot wedge 1122 is the same as that of the partition 1112, thereby effectively improving the connection strength between the slot wedge 1122 and the partition 1112.

In this embodiment, in order to further improve the connection strength between the slot wedge 1122 and the partition 1112, the number of the first connection portion 11222 is more than one, and the multiple first connection portions 11222 are distributed along the length direction of the plug-in portion 11221.

[0115] By adopting the above technical solution, since the first connecting part 11222 extends out of the winding groove 1123 and is connected to the partition 1112, the interference between the partition 1112 and the two adjacent iron cores 1121 can be reduced, thereby effectively reducing the connection stress between the slot wedge 1122 and the partition 1112, and effectively improving the connection stability between the slot wedge 1122 and the partition 1112.

The first connection part 11222 is connected to the first connection hole 11122, that is, at least a portion of the first connection part 11222 is disposed in the first connection hole 11122. The first connection part 11222 may pass through the first connection hole 11122, or may not pass through the first connection hole 11122, which is not specifically limited herein. The shape of the first connection part 11222 is adapted to the shape of the first connection hole 11122.

[0126] By adopting the above technical solution, the connection area between the slot wedge 1122 and the partition 1112 is effectively increased, thereby further improving the connection strength between the slot wedge 1122 and the partition 1112.

[0127] In some embodiments of this application, please refer to Figure 12 to Figure 14 The partition 1112 includes a partition portion 11121 and a second connecting portion 11125.

[0134] By adopting the above technical solution, the connection area between the slot wedge 1122 and the partition 1112 is effectively increased, thereby further improving the connection strength between the slot wedge 1122 and the partition 1112.

[0135] In other embodiments of the present application, please refer to Fig.13 The slot wedge 1122 includes an inserting portion 11221, which is inserted into the winding slot 1123. The inserting portion 11221 is provided with a second connecting hole 11225, and the second connecting portion 11125 is connected to the second connecting hole 11225.

[0139] By adopting the above technical solution, the connection area between the slot wedge 1122 and the partition 1112 is effectively increased, thereby further improving the connection strength between the slot wedge 1122 and the partition 1112.

[0140] In some embodiments of this application, please refer to Figure 8 The slot wedge 1122 includes an inserting portion 11221 and a limiting portion 11227 . The inserting portion 11221 is inserted into the winding slot 1123 . The limiting portion 11227 is connected to one end of the inserting portion 11221 and abuts against two adjacent cores 1121 .

[0141] The limiting portion 11227 is a component used to limit the depth position of the plug-in portion 11221 inserted into the winding groove 1123. In some embodiments, the limiting portion 11227 and the plug-in portion 11221 are perpendicular to each other. When the plug-in portion 11221 is plugged into the winding groove 1123, one end of the limiting portion 11227 abuts against one iron core 1121, and the other end of the limiting portion 11227 abuts against the other iron core 1121. At this time, the plug-in portion 11221 cannot continue to be inserted into the winding groove 1123. The limiting portion 11227 can be integrally formed with the plug-in portion 11221, for example, the limiting portion 11227 and the plug-in portion 11221 are integrally formed by an injection molding process, and the limiting portion 11227 can be separately connected to the plug-in portion 11221, for example, the limiting portion 11227 and the plug-in portion 11221 are separately formed and then connected together.

[0142] By adopting the above technical solution, the position of the slot wedge 1122 in the winding groove 1123 is effectively limited, thereby effectively reducing the risk of the slot wedge 1122 escaping from the winding groove 1123.

[0143] In some embodiments of this application, please refer to Figure 8 An avoidance opening 11228 is provided at the connection between the plug-in portion 11221 and the limiting portion 11227 .

[0144] It can be understood that the avoidance opening 11228 is recessed at the connection between the plug-in portion 11221 and the limiting portion 11227. In some embodiments, the avoidance opening 11228 is provided on one side of the connection between the plug-in portion 11221 and the limiting portion 11227. In other embodiments, the avoidance opening 11228 is provided on opposite sides of the connection between the plug-in portion 11221 and the limiting portion 11227.

[0145] During actual use, a corner of the iron core 1121 close to the winding groove 1123 is likely to interfere with the connection between the plug-in portion 11221 and the limiting portion 11227, resulting in the plug-in portion 11221 being unable to be fully inserted into the winding groove 1123. By providing an avoidance opening 11228 at the connection between the plug-in portion 11221 and the limiting portion 11227, the iron core 1121 is effectively avoided, thereby effectively improving the mutual interference between the slot wedge 1122 and the iron core 1121.

[0146] In some embodiments of this application, please refer to Figure 8The slot wedge 1122 includes an inserting portion 11221 , which is inserted into the winding slot 1123 , and a chamfered structure 11229 is provided at the inserting end of the inserting portion 11221 .

[0147] The insertion end of the plug-in portion 11221 refers to the end of the plug-in portion 11221 that first enters the winding groove 1123 during the process of inserting the plug-in portion 11221 into the winding groove 1123. In the direction in which the plug-in portion 11221 is inserted into the winding groove 1123, the width of the insertion end of the plug-in portion 11221 gradually increases to form a chamfered structure 11229. The chamfered structure 11229 can be a chamfered structure or a rounded structure, which is not specifically limited here.

One side of the groove wedge 1122 is inserted into the first card slot 11233, and the other side of the groove wedge 1122 is inserted into the second card slot 11234.

[0150] It can be understood that the first slot wall 11231 is a side wall of one core 1121, and the second slot wall 11232 is a side wall of another core 1121 adjacent to the core 1121. The first slot wall 11231 and the second slot wall 11232 are spaced apart to form a winding slot 1123. The first slot wall 11231 is recessed in a direction away from the second slot wall 11232 to form a first slot 11233, and the second slot wall 11232 is recessed in a direction away from the first slot wall 11231 to form a second slot 11234. When the slot wedge 1122 is inserted into the winding slot 1123, one side of the slot wedge 1122 is inserted into the first slot 11233, and the other side of the slot wedge 1122 is inserted into the second slot 11234. In this way, the first slot wall 11231 and the second slot wall 11232 jointly limit the slot wedge 1122 along its width direction (for example, Figures 9 to 14 The first slot 11233 and the second slot 11234 jointly limit the position of the slot wedge 1122 along its thickness direction (for example, Figures 9 to 14 The position of the X direction as shown.

[0151] By adopting the above technical solution, the position of the slot wedge 1122 in the winding groove 1123 is effectively limited, thereby effectively reducing the risk of the slot wedge 1122 escaping from the winding groove 1123.

[0152] In some embodiments of this application, please refer to Figures 8 to 14 The slot wedge 1122 includes an insert portion 11221 and a limiting portion 11227.

The first slot wall 11231 is provided with a first card slot 11233, and the second slot wall 11232 is provided with a second card slot 11234 that is opposite to the first card slot 11233. One side of the insert portion 11221 is inserted into the first card slot 11233, and the other side of the insert portion 11221 is inserted into the second card slot 11234.

[0153] By adopting the above technical solution, the limiting portion 11227 limits the position of the plug-in portion 11221 along its length direction, and the first slot wall 11231 and the second slot wall 11232 jointly limit the slot wedge 1122 along its width direction (for example, Figures 9 to 14 The first slot 11233 and the second slot 11234 jointly limit the position of the slot wedge 1122 along its thickness direction (for example, Figures 9 to 14 The position of the slot wedge 1122 in the winding groove 1123 is effectively limited, thereby effectively reducing the risk of the slot wedge 1122 escaping from the winding groove 1123.
