For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] It should be understood that the reference to "one embodiment" throughout the specification means that the specific features, structures or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the "in some embodiments" that appear throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0033] The following describes in detail a motor, a drive assembly and a vehicle provided by the present invention by listing specific embodiments.

[0034] Reference Figure 1 and Figure 2 An embodiment of the present invention provides a motor, comprising a housing 1; the housing 1 has a center line 10 passing through the center position of the housing 1; a wiring port 11 is provided on the side of the housing 1, and the wiring port 11 is symmetrically structured with the center line 10 as the axis.

[0035] Specifically, the motor of the embodiment of the present invention is installed near the wheel of the vehicle and is used to drive the wheel to move. Each vehicle includes a left motor and a right motor. The left motor is used to drive the wheel on the left side of the vehicle to move, and the right motor is used to drive the wheel on the right side of the vehicle to move. The motor includes a housing 1, and the housing 1 has a housing cavity. The housing cavity is provided with a stator assembly, a rotor assembly, etc. The rotor assembly is located inside the stator assembly to form an inner rotor motor, and the rotor assembly is located outside the stator assembly to form an outer rotor motor. The stator assembly includes a stator core 31, a stator winding 32, etc. The rotor assembly includes a rotor body and a rotating shaft, etc. The stator winding 32 is wound on the stator core 31. After power is turned on, a rotating magnetic field is formed. Under the action of the rotating magnetic field, the rotor body starts to rotate and drives the rotating shaft to rotate synchronously, thereby converting electrical energy into mechanical energy to achieve power output of the motor.

[0036] like Figure 1 and Figure 2 As shown, the housing 1 has a center line 10, and the center line 10 passes through the center position of the housing 1. The number of center lines 10 can be multiple. If the housing 1 is a circular structure, the center line 10 is any diameter of the circular structure. If the housing 1 is a square structure, the center line 10 is any diagonal of the square structure. If the housing 1 is a polygonal structure, the center line 10 is any straight line passing through the center of the polygonal structure. The side of the housing 1 is provided with a wiring port 11. The wiring port 11 and the housing 1 can be an integrally processed structure, or a structure formed by assembly connection or welding, which is not limited in this embodiment. The wiring port 11 is the power access part of the motor. The motor is electrically connected to an external power supply through the wiring port 11, so that the motor provides power output for the wheel after power is turned on.

[0037] The wiring port 11 is symmetrical with the center line 10 as the axis, so that the overall structure of the housing 1 of the left motor and the right motor of the vehicle is substantially the same. During the processing, the housing 1 of the left motor and the right motor can be cast using a common set of molds. After the prototype of the housing 1 of the left motor and the right motor is completed using the same mold, a cooling cavity for circulating coolant is processed on the housing 1 of the left motor and the right motor separately through a relatively small mold, and finally two motors with the same basic structure but different internal structures are obtained. The processing method of this motor can effectively reduce the types of molds, save mold development costs, and control production costs. At the same time, the reduction in the types of molds also helps to improve the production efficiency of the housing 1, thereby shortening the manufacturing cycle of the motor.

[0038] The motor of the present invention includes a shell 1, and the shell 1 has a center line 10 passing through the center position of the shell 1. The side of the shell 1 is provided with a wiring port 11, and the wiring port 11 is symmetrically structured with the center line 10 as the axis, so that the overall structure of the motor for driving the left wheel and the motor for driving the right wheel on the vehicle are substantially the same. During the processing, the shells 1 of the two motors can be cast using a common set of molds, thereby reducing the types of molds, saving mold development costs, and helping to reduce the overall production cost of the motor. At the same time, the reduction in the types of molds also helps to improve the production efficiency of the motor, thereby shortening the manufacturing cycle of the motor.

[0039] Optionally, refer to Figures 1 to 4 The shell 1 includes a bottom shell 21 and an end cover 22; the bottom shell 21 is fixedly connected to the end cover 22, and the end cover 22 is used to cover the bottom shell 21; a first wiring body 210 is provided at the edge of the bottom shell 21, and a second wiring body 220 is provided at the edge of the end cover 22, and the first wiring body 210 and the second wiring body 220 cooperate to form the wiring port 11.

[0040] Specifically, the housing 1 includes a bottom housing 21 and an end cover 22. The center line 10 of the housing 1 is also applicable to the bottom housing 21 and the end cover 22. Figure 3 A schematic diagram of a bottom shell 21 is shown. Figure 4 The schematic diagram of an end cover 22 is shown. The bottom shell 21 has a receiving cavity, and the stator assembly, rotor assembly, etc. are arranged in the receiving cavity. The end cover 22 is fixedly connected to the shell 1 by fasteners such as bolts and screws. The end cover 22 can cover the receiving cavity in the shell 1 to prevent water vapor, dust, etc. from entering the shell 1, thereby protecting the components in the shell 1. Figure 3 As shown, the first wiring body 210 is disposed at the edge of the bottom shell 21, and the first wiring body 210 is symmetrically structured with the center line 10 as the axis. Figure 4 As shown, a second wiring body 220 is disposed on the edge of the end cover 22 . The second wiring body 220 is symmetrically structured with the center line 10 as an axis. The first wiring body 210 cooperates with the second wiring body 220 to form a wiring port 11 of the housing 1 .

[0041] Optionally, refer to Figure 3 Four coolant ports 12 are provided on the shell 1, and the four coolant ports 12 are symmetrically arranged along the center line 10; wherein, one of the two coolant ports 12 on the same side is used to inject coolant into the shell 1, and the other of the two coolant ports 12 on the same side is used to discharge coolant from the shell 1.

[0042] Specifically, during the operation of the motor, the stator assembly, rotor assembly, etc. in the housing 1 will generate heat, causing the temperature inside the housing 1 to rise, so four coolant ports 12 are provided on the housing 1, and the four coolant ports 12 are symmetrically arranged along the center line 10 of the housing 1. The four coolant ports 12 include two liquid inlets and two liquid outlets, and the liquid inlets are connected to a pumping device, which can pump the coolant from the liquid inlet into the housing 1. After the coolant flows in the cooling liquid cavity of the housing 1 and continuously absorbs heat and heats up, it flows out of the housing 1 through the liquid outlet, and after being cooled by the external cooling device, it is injected into the housing 1 again by the pumping device, and the coolant cools the inside of the housing 1 in this cycle.

[0043] In this embodiment, the liquid inlet is symmetrically arranged along the center line 10 of the shell 1, and the liquid outlet is symmetrically arranged along the center line 10 of the shell 1, that is, a liquid inlet and a liquid outlet are respectively arranged on both sides of the center line 10 of the shell 1, and the liquid inlet of the two coolant ports 12 on the same side is used to inject coolant into the shell 1, and the liquid outlet is used to discharge coolant from the shell 1. It should be noted that during the operation of the motor, the two coolant ports 12 on one side of the center line 10 of the shell 1 are opened for the coolant to enter and exit, and the two coolant ports 12 on the other side are blocked and the coolant cannot enter and exit. Specifically, the opening or blocking state of the coolant ports 12 on both sides can be adaptively selected according to the installation position of the motor, and the opening or blocking state of the left motor and the right motor are opposite. In some embodiments, a plugging cover can be set at the coolant port 12, and the plugging cover is rotated to realize the opening or blocking of the coolant port 12; a plugging can also be set at the coolant port 12, and the plugging can be pulled out or inserted to realize the opening or blocking of the coolant port 12. The specific setting method is not limited in this embodiment.

[0044] Furthermore, in the present embodiment, the number of coolant ports 12 can also be six, eight, ten, etc., to ensure that the total number of coolant ports 12 is an even number, and the multiple coolant ports 12 are symmetrically arranged along the center line 10 of the shell 1, so that both sides of the center line 10 of the shell 1 include multiple liquid inlets and liquid outlets. During the operation of the motor, the coolant ports 12 on one side of the center line 10 of the shell 1 are opened, and the coolant ports 12 on the other side are blocked. Of course, some of the inlets and outlets on one side of the center line 10 of the shell 1 can also be opened, and some of the inlets and outlets can be blocked. When there are a large number of coolant ports 12, the way of coolant entering and exiting the shell 1 is more flexible, which helps to improve the cooling effect.

[0045] In addition, an embodiment of the present invention provides another motor, which is installed near the wheels of the vehicle and is used to drive the wheels to move. Each vehicle includes a left motor and a right motor. The left motor is used to drive the wheels on the left side of the vehicle to move, and the right motor is used to drive the wheels on the right side of the vehicle to move. The motor includes a housing 1, and the housing 1 has a center line 10 passing through the center position of the housing 1. The number of center lines 10 can be multiple. If the housing 1 is a circular structure, the center line 10 is any diameter of the circular structure. If the housing 1 is a square structure, the center line 10 is any diagonal line of the square structure. If the housing 1 is a polygonal structure, the center line 10 is any straight line passing through the center of the polygonal structure. Four coolant ports 12 are provided on the housing 1, and the four coolant ports 12 are symmetrically arranged along the center line 10 of the housing 1, wherein one of the two coolant ports 12 on the same side is used to inject coolant into the housing 1, and the other of the two coolant ports 12 on the same side is used to discharge coolant from the housing 1, that is, the four coolant ports 12 include two inlets and two outlets, the two inlets are symmetrically arranged along the center line 10 of the housing 1, and the two outlets are symmetrically arranged along the center line 10 of the housing 1. Of course, the coolant ports 12 in this embodiment can also be provided with six, eight, ten, etc., to ensure that the total number of the coolant ports 12 is an even number, and the multiple coolant ports 12 are symmetrically arranged along the center line 10 of the housing 1. The coolant ports 12 in the motor of this embodiment are symmetrically arranged along the center line 10 of the housing 1, so that during the processing, the housings 1 of the left motor and the right motor can be cast by a common set of molds, thereby reducing the types of molds, saving mold development costs, and controlling production costs. At the same time, the reduction in the types of molds also helps to improve the production efficiency of the housing 1, thereby shortening the manufacturing cycle of the motor.

[0046] Optionally, refer to Figures 1 to 3 The housing 1 is provided with two mounting surfaces 13 , and the two mounting surfaces 13 are symmetrically arranged along the center line 10 ; wherein a sensor mounting structure is arranged on one of the mounting surfaces 13 .

[0047] Specifically, if Figure 3 As shown, when processing the prototype of the housing 1, two mounting surfaces 13 are cast on the housing 1 at one time. The two mounting surfaces 13 are symmetrically arranged along the center line 10. In the subsequent processing of the housing 1, one of the two mounting surfaces 13 is selected to be processed on its surface to form a sensor mounting structure, and the other is not processed. The sensor mounting structure is used to install the temperature sensor 5. The temperature sensor 5 is used to detect the temperature of the stator winding 32 in the motor. The wire harness inside the temperature sensor 5 is tied to the stator winding 32. Figure 1 As shown, if the motor is installed at the left wheel, the sensor installation structure is formed on the installation surface 13 close to the right of the two installation surfaces 13, such as Figure 2As shown, if the motor is installed at the right wheel, a sensor installation structure is formed on the installation surface 13 close to the left of the two installation surfaces 13 to increase the installation height of the temperature sensor 5 and ensure that the temperature sensor 5 works normally.

[0048] In addition, an embodiment of the present invention provides another motor, which is installed near the wheels of the vehicle and is used to drive the wheels to move. Each vehicle includes a left motor and a right motor. The left motor is used to drive the wheels on the left side of the vehicle to move, and the right motor is used to drive the wheels on the right side of the vehicle to move. The motor includes a housing 1, and the housing 1 has a center line 10 passing through the center position of the housing 1. The number of center lines 10 can be multiple. If the housing 1 is a circular structure, the center line 10 is any diameter of the circular structure. If the housing 1 is a square structure, the center line 10 is any diagonal line of the square structure. If the housing 1 is a polygonal structure, the center line 10 is any straight line passing through the center of the polygonal structure. Two mounting surfaces 13 are provided on the housing 1. The two mounting surfaces 13 are symmetrically arranged along the center line 10 of the housing 1. Among them, a sensor mounting structure is provided on one mounting surface 13, and the sensor mounting structure is used to install a temperature sensor. That is, when processing the prototype of the housing 1, two mounting surfaces 13 are cast on the housing 1 at one time, and the two mounting surfaces 13 are symmetrically arranged along the center line 10. In the subsequent processing of the housing 1, one of the two mounting surfaces 13 is selected to be processed on its surface to form a sensor mounting structure, and the other is not processed. The two mounting surfaces 13 for mounting the temperature sensor in the motor of this embodiment are symmetrically arranged along the center line 10 of the housing 1, so that during the processing, the housings 1 of the left motor and the right motor can be cast by using a common set of molds, thereby reducing the types of molds, saving mold development costs, and controlling production costs. At the same time, the reduction in the types of molds also helps to improve the production efficiency of the housing 1, thereby shortening the manufacturing cycle of the motor.

[0049] Optionally, refer to Figure 5 The motor also includes a stator core 31 and a stator winding 32; the stator core 31 is arranged in the housing 1, and the stator core 31 is an annular structure; the stator winding 32 is wound on the stator core 31, and the end of the stator winding 32 extends radially outward from the stator core 31 to form a terminal 33, and the terminal 33 is symmetrical with the center line 10 as the axis.

[0050] Specifically, the motor further includes a stator core 31 and a stator winding 32. The stator core 31 is arranged in the housing 1, and the stator core 31 is an annular structure. The stator winding 32 is wound on the stator core 31. When the stator winding 32 is energized, a rotating magnetic field is formed, so that the rotor assembly in the housing 1 rotates to achieve power output. The end of the stator winding 32 extends radially outward along the stator core 31 to form a terminal 33. The terminal 33 is fixed in the wiring port 11. The terminal 33 is used to electrically connect to an external power supply device to achieve power supply to the stator winding 32. The terminal 33 is symmetrical with the diameter of the stator core 31 as the axis, that is, the terminal 33 is symmetrical with the center line 10 of the housing 1 as the axis, so that the stator assembly is symmetrical, so that the stator assembly of the left motor and the right motor of the vehicle can be shared, further reducing the types of materials of the motor and saving material development costs.

[0051] Optionally, refer to Figure 6 The motor also includes a terminal block 4; the terminal block 4 includes a base body 40 and a first terminal slot 41 and a second terminal slot 42 arranged on opposite sides of the base body 40, and the extension direction of the first terminal slot 41 and the extension direction of the second terminal slot 42 are inclined to each other; the first terminal slot 41 is electrically connected to the terminal 33, and the second terminal slot 42 is electrically connected to an external device.

[0052] Specifically, the terminal block 4 includes a base body 40 and a first wiring slot 41 and a second wiring slot 42 arranged on opposite sides of the base body 40. The base body 40, the first wiring slot 41 and the second wiring slot 42 can be an integrally formed structure, or can be welded or assembled together. The first wiring slot 41 and the second wiring slot 42 are provided with electrical connection structures, such as gold fingers, copper-aluminum bars, etc. The first wiring slot 41 is used for inserting the output end of the wiring terminal 33 to achieve electrical connection with the wiring terminal 33, and the second wiring slot 42 is used for inserting the output end of the power supply device to achieve electrical connection with the external power supply device. Since the position of the wiring port 11 on the housing 1 of the motor in the embodiment of the present invention has changed, when the position of the external power supply device remains unchanged, the extension direction of the first wiring slot 41 and the extension direction of the second wiring slot 42 are set to be inclined to each other, and the inclination angle is determined according to the positional relationship between the terminal block 4 and the power supply device, so as to facilitate the layout of the wiring harness between the terminal block 4 and the power supply device, simplify the wiring method, and ensure the reliability of the electrical connection.

[0053] Optionally, refer to Figure 1 and Figure 2 The shell 1 is a circular structure, and the shell 1 is a symmetrical structure with the center line 10 as the axis.

[0054] Specifically, in some embodiments, the shell 1 is set to a circular structure, and the edge of the circular shell 1 extends in a direction away from the center of the circle to form a wiring port 11. For ease of processing, the wiring port 11 can be set to a rectangular structure symmetrical along the center line 10 of the shell 1. At the same time, the shell 1 is a symmetrical structure with its center line 10 as the axis. The shell 1 with a completely symmetrical structure is more convenient for the common use of the left motor and the right motor, and is also more convenient for mold making, which controls production costs.
