Fig. 1 shows a schematic structural diagram of a motor provided in an embodiment of the present invention when the motor is connected to a temperature monitoring device. Referring to fig. 1, the motor includes a body (not shown), a busbar 100, and an elastic sleeve 200. Wherein the body comprises stator windings (not shown in the figures). The bus bar 100 includes a main body portion 110 and a heat conductive portion 120, the main body portion 110 is connected to the stator winding, and the heat conductive portion 120 is connected to the main body portion 110 and extends in a first direction. The elastic sleeve 200 is configured to be sleeved on the heat conduction portion 120, and a positioning hole (not labeled) is formed between an inner surface of the elastic sleeve 200 and the heat conduction portion 120. The positioning hole is used for loading a temperature measuring part 310 of a temperature monitoring device. When the temperature measuring part 310 is inserted into the positioning hole, the elastic sleeve 200 deforms and applies an acting force to the temperature measuring part 310 so that the temperature measuring part 310 is in close contact with the heat conduction part 120, and thus the temperature measuring part 310 can accurately measure the temperature of the heat conduction part 120, and further the temperature of the busbar 100, so as to monitor the temperature in the motor. In this embodiment, the bus bar 100 is redesigned to have a heat conduction portion 120, and the heat conduction portion 120 and the elastic sleeve 200 can clamp the temperature measuring end 310 of the temperature monitoring device together, so that when the temperature monitoring device of the motor is replaced, only the end cover of the motor needs to be detached and the temperature measuring end is pulled out from the positioning hole, and the operation is simple and convenient. The temperature monitoring device is for example an NTC.
The shape of the cross section of the positioning hole is not particularly limited in this embodiment, and may be matched with the shape of the cross section of the temperature measuring part 310. For example, when the temperature measuring part 310 has a cylindrical structure, the cross section of the positioning hole may be circular or other shapes. It can be understood that the diameter of the temperature measuring part 310 should be slightly larger than that of the positioning hole, so that the elastic sleeve 200 can deform when the temperature measuring part 310 is inserted into the positioning hole, and thus the elastic sleeve 200 can press the temperature measuring part 310, and the temperature measuring part 310 is in close contact with the heat conduction part 120 under the pressing of the elastic sleeve 200.
In an exemplary embodiment, as shown in fig. 2, the thermally conductive portion 120 is formed with a first positioning groove 121 extending along the first direction, and one end of the first positioning groove 121 near the main body portion 110 has a bottom surface 122. Referring to fig. 3 and 4, the elastic sleeve 200 preferably includes a first sidewall 210, a second sidewall 220, a third sidewall 230 and an elastic clip 240 connected in sequence, wherein the first sidewall 210 and the third sidewall 230 are disposed opposite to each other, and the second sidewall 220 and the elastic clip 240 are disposed opposite to each other. That is, the first sidewall 210, the second sidewall 220, the third sidewall 230 and the elastic clip 240 form a receiving space having an approximately rectangular cross section for receiving the heat conductive portion 120. Wherein, the inner surface of the elastic clip 240 is formed with a second positioning groove 241 penetratingly extending along the axial direction of the elastic sleeve 200, and the cross section of the second positioning groove 241 may be semicircular. The inner surface of the resilient clip 240 refers to the surface of the resilient clip 240 facing the second sidewall 220.
When the elastic sleeve 200 is sleeved on the heat conducting portion 120, the axis of the elastic sleeve 200 extends along the first direction, and the second positioning groove 241 and the first positioning groove 121 are spliced to form the positioning hole, and the bottom surface 122 forms a limiting surface. When the temperature measuring part 310 is inserted into the positioning hole and abuts against the bottom surface 122, the temperature measuring part 310 is installed in place. At this time, since the diameter of the temperature measuring portion 310 is slightly larger than that of the positioning hole, the temperature measuring portion 310 presses the elastic clip 240 outward, and the free end of the elastic clip 240 moves outward (i.e., in a direction away from the second sidewall 220), so as to cause the elastic sleeve 200 to deform, and at the same time, the elastic clip 240 applies a reaction force to the temperature measuring portion 310, so that the temperature measuring portion 310 is in close contact with the heat conduction portion 120. Taking the orientation shown in fig. 1 and 2 as an example, the first direction is a vertical direction, so that the upper end of the heat conductive portion 120 enters the elastic sleeve 200 from the lower end of the elastic sleeve 200.
Further, the elastic sleeve 200 further includes a first limiting member for limiting a maximum distance that the free end of the elastic clip 240 moves outward in the operating state. The operation state is a state in which the temperature measuring part 310 is firmly disposed in the positioning hole and is in close contact with the thermally conductive part 120. The first limiting member is provided to prevent the elastic sleeve 200 from being excessively deformed and fixing the temperature measuring portion 310 in the positioning hole. Specifically, please refer to fig. 3 and 4 with emphasis, a gap is formed between the free end of the resilient clip 240 and the free end of the first sidewall 210. The first limiting member includes a fifth side wall 251 and a first flange 252, the fifth side wall 251 is connected to the free end of the first side wall 210 and is disposed opposite to the second side wall 220, and the first flange 252 is connected to the free end of the fifth side wall 251 and is bent outward (i.e., the first flange 252 extends in a direction away from the second side wall 220). When the free end of the resilient clip 240 moves outward against the first flange 252 under the external force, the distance of movement reaches a maximum. It can be appreciated that if the free ends of the resilient clips 240 move outward to abut against the first flanges 252 and continue to move outward, the resilient sleeve 200 will be deformed excessively and fail.
The elastic sleeve 200 has axially opposite first and second ends, the first end being, for example, an upper end of the elastic sleeve 200, and the second end being, for example, a lower end of the elastic sleeve 200 (in the orientation shown in fig. 1 and 2). In order to improve the positioning accuracy and prevent the lower end of the elastic sleeve 200 from scratching the heat conduction part 120, the elastic sleeve 200 further includes a second guide part 260, and the second guide part 260 is disposed at the lower end of the elastic sleeve 200 and used for guiding the heat conduction part 120 to be inserted into the elastic sleeve 200. The second guide portion 260 may include at least one second flange folded toward the outside of the elastic sheath 200. When the second guiding portion 260 includes a plurality of second flanges, a portion of the second flanges may be connected to the second side wall 220, and a portion of the second flanges may also be connected to the resilient clip 240 except for the second positioning slot 241. When the lower end of the fifth sidewall 251 of the first limiting member is flush with the lower end of the elastic clip 240, a part of the second turned edge may also be connected to the lower end of the fifth sidewall 251.
Similarly, when the temperature measuring portion 310 is inserted into the positioning hole, in order to facilitate positioning and avoid the upper edge of the positioning hole from scratching the temperature measuring portion 310, the elastic sleeve 200 further includes a first guiding portion 270 disposed at the upper end of the elastic sleeve 200 and connected to the second positioning groove 241 for guiding the temperature measuring portion 310 to be inserted into the positioning hole. The first guide 270 may be a third flange folded toward the outside of the elastic sheath 200.
Further, with reference to fig. 3 and fig. 4, and with reference to fig. 2, a second limiting member is disposed on the heat conducting portion 120, and a third limiting member is disposed on the elastic sleeve 200, where the third limiting member is used to cooperate with the second limiting member to keep the elastic sleeve 200 and the heat conducting portion 120 relatively stationary in the first direction when the elastic sleeve 200 is in an operating state.
The thermally conductive section 120 has a first side surface and a second side surface opposing each other in a second direction perpendicular to the first direction, that is, in the orientation shown in fig. 2, the second direction is a horizontal direction. When the elastic sleeve 200 is fitted over the heat conductive part 120, the first side surface is at least partially in contact with the inner surface of the first sidewall 210 (i.e., the surface of the first sidewall 210 facing the third sidewall 230), and the second side surface is at least partially in contact with the inner surface of the third sidewall 230 (i.e., the surface of the third sidewall 230 facing the first sidewall 210). In this embodiment, the second limiting members may be disposed on at least one of the first side surface and the second side surface, and preferably, the number of the second limiting members is two and the second limiting members are disposed on the first side surface and the second side surface, respectively. Correspondingly, the number of the third limiting members is also two, and the third limiting members are respectively disposed on the first sidewall 210 and the third sidewall 230. This configuration is advantageous for maintaining the stress balance between the heat conduction portion 120 and the elastic sleeve 300.
Optionally, the second limiting member is a notch 123 disposed on the corresponding side surface. The notch 123 may have a third side surface and a fourth side surface oppositely disposed in the first direction, and a fifth side surface connecting the third side surface and the fourth side surface, wherein the fourth side surface is closer to the main body portion 110 of the bus bar 100 than the third side surface. In other words, taking the orientation shown in fig. 2 as an example, the third side surface is the upper side surface of the notch 123, and the fourth side surface is the lower side surface of the notch 123. The fourth retaining member includes a window 281 disposed on the corresponding sidewall and an elastic buckle 282 disposed in the window 281. The window 281 divides a corresponding sidewall, for example, the first sidewall 210, into two portions spaced apart in the first direction, which are referred to as a first portion 211 and a second portion 212, respectively, for convenience of description, and the second portion 212 is closer to the first end, i.e., the second portion 212 is located above the first portion 211. The elastic buckle 282 is connected to the first portion 211, and particularly, the lower end of the elastic buckle 282 is connected to the upper edge of the first portion 211. The window 281 is configured to correspond to the notch 123, an upper end of the elastic buckle 282 is configured to abut against the third side of the notch 123 to prevent the elastic sleeve 200 from moving upward, and a lower edge of the first portion 211 is configured to abut against the fourth side of the notch 123 to prevent the elastic sleeve 200 from moving downward.

Next, the assembly process of the motor assembly will be described with reference to fig. 1 and 2.
First, the lower end of the elastic cap 200 is aligned with the upper end of the thermally conductive part 120;
then, the elastic case 200 is moved downward such that the upper end of the heat conductive part 120 enters the elastic case 200 along the second guide part 260. In this process, the free ends of the elastic buckles 282 of the two third limiting members are firstly expanded by the first side surface and the second side surface of the heat conducting portion 120, and move along the first side surface and the second side surface to enter the corresponding notches 123. The downward movement of the elastic sleeve 200 is continued until the lower edge of the first portion of the first side wall 210 abuts against the fourth side of the notch 123 (and correspondingly the lower edge of the first portion of the third side wall also abuts against the fourth side of the other notch), while at the same time the free end of the elastic catch 282 abuts against the third side of the corresponding notch 123.
Then, the temperature measuring end 310 of the temperature monitoring device is aligned with the positioning hole, and the temperature measuring end 310 is moved downward, so that the temperature measuring end 310 enters the positioning hole along the first guiding portion 270 until the temperature measuring end 310 abuts against the bottom surface 122 of the first positioning groove 121.
