The words "first", "second" and similar terms used in the patent application specification and claims of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "one" or "the" do not indicate a quantitative limitation, but rather indicate the presence of at least one. Words such as "include" or "comprise" mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0048] Figure 1 It is a schematic assembly diagram of a component mounting assembly 1 according to at least one embodiment of the present disclosure.

[0049] like Figure 1 As shown, the component mounting assembly 1 includes a sensing element 2 , a heat-conducting component 3 and a spring frame 4 , and the sensing element 2 and the heat-conducting component 3 are fixed together by the spring frame 4 .

[0050] The structure of the spring frame 4 is Figure 2 As shown in Figure 2As shown, the spring frame 4 includes a wall 11, a first clamping portion 12 and a second clamping portion 13 extending from the wall 11 along a first direction. The first clamping portion 12 includes a bending structure 121. The second clamping portion 13 includes a hook-shaped structure 132, and the hook-shaped structure 132 is bent toward a second direction opposite to the first direction. In this embodiment, the number of the first clamping portions 12 is 4, which extend from the four sides of the wall 11 along the first direction respectively. It should be noted that the present disclosure does not limit the number of the first clamping portions 12, and the spring frame 4 only needs to include at least two first clamping portions arranged opposite to each other. Figure 2 As shown, the spring frame 4 also includes a third clamping portion 14, and the third clamping portion 14 includes a bending structure 131. In this embodiment, the spring frame 4 is designed as an integrated structure made of stainless steel. In other embodiments, the spring frame 4 can also be made of other materials with elastic force, and the present disclosure does not limit this.

[0051] The spring frame provided by the embodiment of the present disclosure has a compact and simple structure, which can save costs.

[0052] Below through Figure 3 and Figure 4 To illustrate the assembly method of the component mounting assembly provided in the embodiment of the present disclosure.

[0053] like Figure 3 As shown, the sensing element 2 is first placed in the component mounting assembly 1, and the sensing element 2 is pressed toward the wall 11, so that the sensing element 2 is attached to the wall 11 and fixed in the component mounting assembly 1 by the elastic force of the first clamping portion 12. The bending structure 121 of the first clamping portion 12 abuts against the sensing element 2 to apply pressure to the sensing element 2. One of the first clamping portions 12 is provided with an opening for the connection line of the sensing element 2 to pass through.

[0054] like Figure 4 As shown, after the sensing element 2 and the spring frame 4 are installed, the sensing element 2 and the spring frame 4 are moved together in the direction of the arrow shown in the figure, so that the heat conducting component 3 is inserted into the spring frame 4 and the assembly is completed. The schematic diagram of the completed assembly is shown in FIG. Figure 1 As shown. In some embodiments of the present disclosure, the length of the first clamping portion 12 in the first direction does not exceed the thickness of the sensing element 2 in the first direction. Such a size setting allows the spring frame 4 to have enough space for the heat-conducting component 3 to be inserted. In the assembled state of the component mounting assembly 1, the third clamping portion 14 abuts against the heat-conducting component 3 to apply pressure to the heat-conducting component 3 in a second direction opposite to the first direction. Specifically, the bending structure 131 of the third clamping portion 14 abuts against the heat-conducting component 3, and the heat-conducting component 3 is fixed by the metal elastic force of the third clamping portion 14.

[0055] like Figure 4As shown, the heat-conducting component 3 is provided with a receiving portion 311 to receive the second clamping portion 13 of the spring frame 4. In this embodiment, the receiving portion 311 is an opening on the heat-conducting component 3, and in other embodiments, the receiving portion 311 may also be a groove on the heat-conducting component 3. In the assembled state of the component mounting assembly 1, the hook structure 132 of the second clamping portion 13 is received in the receiving portion 311, so that the displacement between the heat-conducting component 3 and the sensing element 2 can be limited.

[0056] It should be noted that, in this embodiment, the spring frame 4 includes the second clamping portion 13 and the third clamping portion 14, or may include only the second clamping portion 13, or the second clamping portion 13 and the third clamping portion 14 may be combined into one structure, that is, the structure has both a bending structure and a hook structure, and the present disclosure does not limit this.

[0057] The component installation assembly provided by the embodiment of the present disclosure can simplify the installation process and eliminate the welding step. Moreover, the component installation assembly has a stable structure, and the displacement of the sensing element in all directions can be limited by the several clamping parts of the spring frame 4. In addition, when the sensing element is damaged, the component installation assembly can be simply disassembled and the sensing element can be replaced. The steps for disassembling the assembled component installation assembly are opposite to the steps for installing the component installation assembly: first, shake the spring frame 4 and pull out the spring frame 4 and the sensing element 2 together, and then take out the sensing element 2 clamped in the spring frame 4, and then the sensing element 2 can be replaced.

[0058] At least one embodiment of the present disclosure further provides a motor, which includes the component mounting assembly provided by at least one embodiment of the present disclosure, wherein the heat-conducting component of the component mounting assembly is disposed on the motor.

[0059] At least one embodiment of the present disclosure further provides a motor, which includes a winding, a bus and a component mounting assembly provided by at least one embodiment of the present disclosure, wherein the bus is connected to the winding, and a heat-conducting component of the component mounting assembly is arranged on the bus.

[0060] Figure 5 The figure is a schematic diagram of assembling a component mounting assembly and a bus bar according to at least one embodiment of the present disclosure.

[0061] like Figure 5 As shown, the motor may include a motor stator (not shown) and a busbar 5 for the motor stator. The busbar 5 is arranged on the winding at the axial end of the stator. The motor may be a new energy high-voltage drive motor, for example, a permanent magnet synchronous flat wire motor.

[0062] like Figure 5As shown, the busbar 5 may include a base 6, a neutral bar 7 and a three-phase busbar 8. The base 6 may include a base body 61 extending along a portion of the circumference of the stator. The neutral bar 7 is arranged on the base body 61 and is electrically connected to the neutral point lead wire 9 of the stator winding. The neutral bar 7 and the base body 61 are connected by welding or integrally formed. The three-phase busbar 8 is a U, V, and W three-phase busbar. The three-phase busbars 8 are each arranged on the base body 61 and are electrically connected to the three-phase lead wires 10 of the stator winding. The three-phase busbar 8 and the base body 61 are connected by welding or integrally formed.

[0063] like Figure 5 As shown, the bus 5 also includes a component mounting assembly 1, and the component mounting assembly 1 includes a sensing element 2, a heat-conducting component 3 and a spring frame 4. The heat-conducting component 3 is a part of the neutral row 7, and the sensing element 2 is, for example, a sensing part of a temperature sensor (such as a thermistor). It should be noted that the sensing element 2 can also be other types of sensing elements, and the present disclosure does not limit this. The sensing element 2 is arranged on the neutral row 7 to sense the temperature of the neutral row 7. The spring frame 4 is used to fix the sensing element 2 and the heat-conducting component 3 together.

[0064] In this embodiment, the heat-conducting component of the component mounting assembly is arranged on the bus. Since the heat transfer effect of the bus is good, the heat-conducting component of the component mounting assembly is arranged on the bus, so that the output signal is more consistent with the actual value. In other embodiments, the heat-conducting component of the component mounting assembly can also be directly arranged on the motor, and the present disclosure does not limit this.

[0065] Based on the above, the motor has the advantages of the component mounting assembly as described above, which will not be repeated here.

[0066] At least one embodiment of the present disclosure further provides a vehicle, which includes a motor provided by at least one embodiment of the present disclosure. The vehicle may be an electrified vehicle, such as a battery electric vehicle (BEV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), a range extended electric vehicle (Range extended EV), or a fuel cell vehicle (FCEV). The vehicle may also be a hydrogen energy vehicle.

[0067] Based on the above, the vehicle has the advantages of the component installation assembly as described above, which will not be repeated here.

[0068] Certain features, structures or characteristics in one or more embodiments of the present application may be appropriately combined.
