Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0048] The embodiment of the present application provides a sensor fixing structure, a motor including the sensor fixing structure, and a vehicle including the motor, wherein the vehicle may be a car, a bus, or a truck. For example, the vehicle may be any one of an electric vehicle / electric vehicle (Electric Vehicle; referred to as EV), a pure electric vehicle (Pure Electric Vehicle / Battery Electric Vehicle; referred to as PEV / BEV), a hybrid electric vehicle (Hybrid Electric Vehicle; referred to as HEV), a range extended electric vehicle (Range Extended Electric Vehicle; referred to as REEV), a plug-in hybrid electric vehicle (Plug-in Hybrid Electric Vehicle; referred to as PHEV), a new energy vehicle (New Energy Vehicle), and a fuel vehicle.

[0049] The motor can drive the axle of the vehicle to rotate so that the vehicle can travel. The motor can include a motor body and a sensor, and the sensor can be connected to the motor body, wherein the motor body refers to the part of the motor excluding the sensor, and the motor body is used to convert electrical energy into mechanical energy to provide a power source for the vehicle, and the sensor is used to obtain the operating parameters of the motor body to ensure the reliability and stability of the motor operation.

[0050] As mentioned in the background technology, currently, the sensor is usually tied to the motor body by a cable tie to fix the sensor on the motor body. However, the cable tie is made of plastic, and the motor will generate a lot of heat during operation, which makes the temperature of the motor high. The plastic cable tie will be damaged or even melted in a high temperature environment, thereby affecting the normal connection between the sensor and the motor body, and reducing the reliability and stability of the connection between the sensor and the motor body.

[0051] Based on the above problems, the embodiment of the present application provides a sensor fixing structure. By adopting a fixing structure made of metal material, the metal material has high strength and rigidity, which can improve the stability and reliability of the fixing structure, and help improve the reliability and firmness of the connection between the sensor and the motor body. Moreover, the metal material has good high temperature resistance and is not prone to deformation or melting at high temperatures, which can effectively reduce or avoid damage to the sensor fixing structure, and can further improve the firmness and reliability of the sensor fixing structure to fix the sensor, thereby effectively improving the firmness and stability of the connection between the sensor and the motor body.

[0052] A sensor fixing structure provided in an embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0054] The present application embodiment provides a sensor fixing structure 100, see Figure 1 As shown, the sensor fixing structure 100 may include a first fixing portion 110 and a second fixing portion 120, wherein the sensor fixing structure 100 may include a first fixing portion 110 and a second fixing portion 120. Figure 2 As shown, the first fixing portion 110 may be surrounded by a first accommodating space 111, and the first accommodating space 111 may be used to place and fix the sensor 200. For example, the first fixing portion 110 may have a first opening (not shown in the figure) connected to the first accommodating space 111, and the sensor 200 may be placed in the first accommodating space 111 through the first opening, so that the sensor 200 can be connected to the first fixing portion 110 through the first accommodating space 111.

[0055] The second fixing portion 120 can be used to be connected to the motor 300 . For example, the second fixing portion 120 can be connected to the motor body, so that the sensor 200 can be connected to the motor body through the sensor fixing structure 100 , so as to achieve installation and fixation of the sensor 200 on the motor 300 .

[0056] Among them, the sensor fixing structure 100 can be a metal part, for example, the sensor fixing structure 100 can be a sheet metal part, which can be made by a bending process. Metal materials have high strength and rigidity, which can improve the stability and reliability of the sensor fixing structure 100, and help improve the reliability and firmness of the connection between the sensor 200 and the motor body. Moreover, metal materials have good high temperature resistance, and are not prone to deformation or melting at high temperatures. They can effectively reduce or avoid damage to the sensor fixing structure 100, and can further improve the firmness and reliability of the sensor fixing structure 100 to fix the sensor 200, thereby effectively improving the firmness and stability of the connection between the sensor 200 and the motor body.

[0058] See also Figure 3 As shown, the sensor fixing structure 100 may include a back plate 130, the first fixing portion 110 and the second fixing portion 120 may both be connected to the back plate 130, and the first fixing portion 110 and the second fixing portion 120 may be respectively located on opposite sides of the back plate 130. This can facilitate the sensor fixing structure 100 to be connected to the sensor 200 and the motor 300, respectively, and can reduce or avoid interference between the sensor 200 and the motor body.

[0059] Among them, combined Figure 4 As shown, the first fixing portion 110 and the back plate 130 can be enclosed together to form a first accommodation space 111, and the second fixing portion 120 and the back plate 130 can be enclosed to form a second accommodation space 121, and the second accommodation space 121 can be used to accommodate and fix the bus 310 and the wire 320 of the motor 300 (refer to Figure 2 As shown), the second fixing portion 120 can be connected to the motor 300 via a bus bar 310 and a wire 320.

[0060] For example, the second fixing portion 120 may also have a second opening (not shown in the figure) communicating with the second accommodation space 121, and the busbar 310 and the wire 320 may extend into the second accommodation space 121 through the second opening, so that the busbar 310 and the wire 320 may be connected to the second fixing portion 120. In this way, the separation between the second fixing portion 120 and the motor 300 may be reduced or avoided, which helps to improve the reliability and stability of the connection between the second fixing portion 120 and the motor 300.

[0062] See also Figure 5 As shown, the first fixing part 110 may include a first arm 112 and a second arm 113. The first arm 112 and the second arm 113 may be arranged side by side and both connected to the back plate 130.

The end of the first arm 112 facing away from the second arm 113 may have a first opening, and the sensor 200 may extend into the first accommodation space 111 through the first opening to achieve connection with the first fixing part 110.

[0063] By wrapping the sensor 200 with the first arm 112 and the second arm 113, the firmness and reliability of the connection between the sensor 200 and the sensor fixing structure 100 can be improved, and the sensor 200 can be reduced or prevented from falling off from the first fixing part 110, thereby effectively improving the reliability and stability of the sensor 200 fixed on the motor 300.

[0064] Continue to see Figure 5 As shown, a first notch 1121 may be provided on the first arm 112, and a second notch 1131 may be provided on the second arm 113. By changing the sizes of the first notch 1121 and the second notch 1131, the size of the first accommodating space 111 may be adjusted to improve the reliability and stability of the first arm 112 and the second arm 113 wrapping the sensor 200, which helps to further improve the firmness and reliability of the connection between the sensor 200 and the first fixing portion 110.

[0065] In the embodiment of the present application, the sensor fixing structure 100 may further include a tray (not shown in the figure), which may be connected to the back plate 130, and the tray may be located at one end of the second arm 113 facing away from the first arm 112. When the sensor 200 is located in the first accommodating space 111, it may be located on the tray. The tray may support the sensor 200 and prevent the sensor 200 from falling from the first accommodating space 111, thereby helping to improve the reliability and stability of the sensor 200 in the first accommodating space 111.

The first enclosure 122 and the second enclosure 123 may limit and fix the busbar 310 and the wire 320 on the motor 300, which can effectively prevent the busbar 310 and the wire 320 from escaping from the second accommodation space 121, and help improve the firmness and reliability of the connection between the busbar 310 and the wire 320 and the second fixing portion 120, thereby effectively improving the reliability and stability of the connection between the second fixing portion 120 and the motor 300.

[0068] Continue to see Figure 6 As shown, the first enclosure 122 may have a limiting protrusion 1221 on one side facing the second enclosure 123 , and one end of the limiting protrusion 1221 may abut against the bus 310 in the motor 300 , thereby improving the reliability and stability of the bus 310 in the second accommodating space 121 .

[0069] Continue to see Figure 6 As shown, the second enclosure 123 may have a spring piece 1231 on one side facing the second accommodation space 121, and the spring piece 1231 may deflect toward the second accommodation space 121.
