[0054] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0055] refer to Figures 1 to 8 The embodiment of the present application provides a spring clip 10 for a temperature sensor, comprising a base 11, a spring leg 12 and a sensor holder 13. The base 11 comprises a first flat portion 111 extending along a first plane, the spring leg 12 is arranged at the front side of the first flat portion 111, and the sensor holder 13 is arranged at the rear side of the first flat portion 111. The spring leg 12 is configured to form a clamping space 120 for clamping a temperature sensing target (e.g., a conductor 30) between the spring leg 12 and the first flat portion 111, and the sensor holder 13 is configured to form an accommodating space 130 for accommodating a temperature sensor 20 between the spring leg 12 and the first flat portion 111. The sensor holder 13 comprises a surrounding arm 131 at least partially surrounding the temperature sensor 20, so that the sensor holder 13 can fix the temperature sensor 20 in the accommodating space 130 by means of the surrounding arm 131. The temperature sensing target (e.g., conductor 30) is clamped in the clamping space 120 by the spring legs 12, and the temperature sensor 20 is fixed in the accommodating space 130 by means of the surrounding arms 131 that at least partially surround the temperature sensor 20, so that the temperature sensing target and the temperature sensor 20 are respectively fixed on the front and rear sides of the spring clip 10. In this way, the heat of the temperature sensing target can be transferred to the temperature sensor 20 through the base 11 to detect the temperature of the temperature sensing target. Compared with the current solution on the market that fixes the temperature sensor 20 to the stator assembly by binding wire or epoxy glue or silicone, the above-mentioned spring clip 10 has a simple assembly process, convenient disassembly, good product consistency, is suitable for mass production, and has high production efficiency.

[0056] The sensor holder 13 is configured to form a first opening 14 for inserting the temperature sensor 20 into the accommodation space 130, and the surrounding arm 131 is provided at the first opening 14. By providing the surrounding arm 131 at the first opening 14 of the accommodation space 130, when the temperature sensor 20 is installed in place, the portion of the temperature sensor 20 located at the first opening 14 or the portion located outside the accommodation space 130 can be surrounded by the surrounding arm 131 to be fixed, and the portion of the temperature sensor 20 located within the accommodation space 130 can be fixed by other components of the sensor holder 13, so that the temperature sensor 20 is fixed in the accommodation space 130.

[0057] Exemplarily, the sensor holder 13 further includes a second flat portion 132 extending along a second plane parallel to the first plane, a first connecting portion 133 for connecting the second flat portion 132 to the first flat portion 111 at the bottom of the spring clip 10, and a first side wall 134 and a second side wall 134 extending forward from two opposite side portions of the second flat portion 132, respectively. It should be noted that, in this article, when "bottom" is mentioned, it refers to the lowest or lower part of the corresponding component, and when "top" is mentioned, it refers to the highest or upper part of the corresponding component. The accommodating space 130 is formed between the first flat portion 111 and the second flat portion 132, and is surrounded by the first flat portion 111, the first connecting portion 133, the second flat portion 132, the first side wall 134 and the second side wall 134. When the temperature sensor 20 is inserted into place, the first connecting portion 133 can abut the bottom 201 of the temperature sensor 20 to make the temperature sensor 20 more stable in the accommodating space 130. In some examples, when the temperature sensor 20 is inserted into place, the first side wall 134 and the second side wall 134 may respectively abut the two side portions 202 of the temperature sensor 20. In this way, the portion of the temperature sensor 20 located within the accommodation space 130 may be fixed by the first side wall 134, the second side wall 134 and the first connecting portion 133. In addition to further fixing the temperature sensor 20 from the side, the first side wall 134 and the second side wall 134 may also protect the temperature sensor 20.

[0058] The first opening 14 is opposite to the first connection portion 133, so that the temperature sensor 20 can be inserted into the accommodation space 130 from above in the longitudinal direction through the first opening 14. The second flat portion 132 extends upward beyond the first opening 14, and the surrounding arm 131 is arranged above the first opening 14 and at least partially surrounds the temperature sensor 20 in the transverse direction. It should be noted that, in this document, when "longitudinal" is mentioned, it refers to the up-and-down direction shown in the drawings, and when "lateral" is mentioned, it refers to the direction perpendicular to the longitudinal direction, such as the direction from the first side wall 134 to the second side wall 134.

[0059] The surrounding arm 131 includes a root section 1311 extending forward from the second flat portion 132 and an extension section 1312 bent from the root section 1311 toward the temperature sensor 20, so that the surrounding arm 131 can at least partially surround the temperature sensor 20. In some examples, the surrounding arm 131 can apply a spring force to the temperature sensor 20, so that the sensor holder 13 fixes the temperature sensor 20 in the accommodation space 130 by means of the spring force applied by the surrounding arm 131. In these examples, the temperature sensor 20 may not have the protrusion 221 as shown in the figure, but only fixes it by means of the spring force applied by the surrounding arm 131 to the temperature sensor 20. In some examples, the surrounding arm 131 is configured so that when the temperature sensor 20 is inserted into place, the protrusion 221 on the temperature sensor 20 is stuck between the surrounding arm 131 and the first opening 14, so that the sensor holder 13 fixes the temperature sensor 20 in the accommodation space 130 by means of the cooperation between the surrounding arm 131 and the protrusion 221. In these examples, the surrounding arm 131 may not apply a spring force to the temperature sensor 20, but only rely on the protrusion 221 on the temperature sensor 20 to be locked between the surrounding arm 131 and the first opening 14 to fix the temperature sensor 20. In some examples, the surrounding arm 131 may both apply a spring force to the temperature sensor 20 and lock the protrusion 221 of the temperature sensor 20 between the surrounding arm 131 and the first opening 14 to fix the temperature sensor 20.

[0060] In the illustrated example, the surrounding arm 131 includes a first surrounding arm 131 and a second surrounding arm 131 that are arranged opposite to each other. The first surrounding arm 131 and the second surrounding arm 131 extend forward from two opposite side portions of the second flat portion 132 and then bend toward the temperature sensor 20, respectively, so as to surround the temperature sensor 20 from two opposite side portions 202 of the temperature sensor 20 to the middle. Although not shown in the figure, it should be understood that in other examples, the surrounding arm 131 may include only one surrounding arm. Such a surrounding arm may include a root section 1311 extending forward from one side portion of the second flat portion 132 and an extension section bent from the root section 1311 toward the temperature sensor 20. In the case of including only one surrounding arm, the extension section included in such a surrounding arm may be longer than the extension length of the illustrated extension section 1312, for example, it may extend to cover the entire width of the temperature sensor 20 from the lateral direction, and may even bend toward the direction of the second flat portion 132 after extending beyond the front surface of the temperature sensor 20, so as to surround the temperature sensor 20 more.

[0061] Exemplarily, the spring leg 12 includes a second connection portion 121, a spring leg body portion 122, and an end portion 123. The second connection portion 121 is used to connect the spring leg body portion 122 to the first flat portion 111 at the top of the first flat portion 111. The spring leg body portion 122 extends downward from the second connection portion 121 and extends in the direction of the first flat portion 111 (i.e., obliquely to the rear). The end portion 123 extends downward from the spring leg body portion 122 and extends in a direction away from the first flat portion 111 (i.e., obliquely to the front). A second opening 15 for inserting a temperature sensing target (e.g., conductor 30) into the clamping space 120 is formed between the end portion 123 and the first flat portion 111.

[0062] In some examples, the spring leg 12 further includes a spring sheet 124 extending from the spring leg body 122 to the interior of the clamping space 120. As shown in the figure, an opening 1220 is provided on the spring leg body 122 (see Figure 5 6), the spring sheet 124 extends upward and backward from the lower edge of the opening to form an elastic sheet 124 extending into the clamping space 120. When the temperature sensing target (e.g., the conductor 30) is installed in place, the spring sheet 124 can cooperate with the limiting groove 311 on the temperature sensing target to limit the temperature sensing target (see Figure 8 On the one hand, the spring piece 124 is limited in the limiting groove 311 so as to limit the temperature sensing target (for example, both longitudinally and transversely) to further fix the temperature sensing target; on the other hand, the spring piece 124 can apply pressure to the temperature sensing target to clamp the temperature sensing target in the clamping space 120.

[0063] In some examples, the base 11 further includes a first limiting plate 112 and a second limiting plate 113 extending forward from two opposite side portions of the first flat portion 111, respectively. The first limiting plate 112 and the second limiting plate 113 are configured to abut against two opposite side portions of the temperature sensing target when the temperature sensing target is inserted into the clamping space 120. By providing the limiting plates 112 and 113, a limit (e.g., a lateral limit) is formed on the temperature sensing target to further clamp the temperature sensing target in the clamping space 120. In this way, the spring clamp 10 can not only apply a spring force to the temperature sensing target through the spring leg body 122 to clamp the temperature sensing target, but also limit the temperature sensing target in both the longitudinal and lateral directions through the spring sheet 124 and the limiting plates 112 and 113, which can effectively prevent the temperature sensing target from being unexpectedly displaced in the clamping space 120, such as being completely or partially detached from the spring clamp 10 due to vibration or the like.

[0064] In some examples, the base 11 further includes an anti-mistake inclined plate 114 extending upward from the upper portion of the second limit plate 113 and toward the inside of the clamping space 120. The anti-mistake inclined plate 114 is used to cooperate with the chamfer on the temperature sensing target. In this way, the temperature sensing target can be inserted into the clamping space 120 in a unique state (i.e., the state in which the chamfer abuts against the anti-mistake inclined plate 114), thereby preventing errors during installation.

[0065] In some examples, the base 11 further includes a relief portion 115 bent backward from the top of the first flat portion 111. The second connection portion 121 is connected to the first flat portion 111 via the relief portion 115. The relief portion 115 can prevent the top of the temperature sensing target from colliding with or scratching the top of the base 11, and can effectively prevent the temperature sensing target and the spring clip 10 from damaging each other, especially when frequent vibrations are generated during operation.

[0066] The spring clip 10 according to the embodiment of the utility model can be used in a motor to detect the temperature of an electric conductor 30 (e.g., an input and output copper busbar) in the motor. The conductor end 31 of the electric conductor 30 can be inserted into the clamping space 120 as a temperature sensing target so that the spring leg 12 and the first flat portion 111 clamp the conductor end 31; the temperature sensor 20 is inserted into the accommodating space 130 so that the temperature sensor 20 is accommodated between the sensor holder 13 and the first flat portion 111, and the temperature sensor 20 is fixed in the accommodating space 130 by means of the surrounding arm 131; thus, the temperature sensor 20 can be used to sense the temperature of the conductor end 31. The temperature sensor 20 includes a thermistor 21 and an insulating housing 22 formed by covering the thermistor 21 with an insulating material (e.g., plastic). The insulating housing 22 is provided with a protrusion 221 that can cooperate with the surrounding arm 131. It should be understood that the position of the protrusion 221 of the temperature sensor 20 should be such that when the temperature sensor 20 is inserted into place (for example, when the bottom 201 of the temperature sensor 20 abuts the first connection portion 133), the protrusion 221 is stuck between the surrounding arm 131 and the first opening 14 of the accommodating space 130. In addition, the thermistor 21 of the temperature sensor 20 needs to be connected to the cable 40 to transmit the sensing signal, etc.

[0067] refer to Figure 8, the embodiment of the present application also provides a motor system, including a stator (only a part is shown), a temperature sensor 20 and a spring clip 10 for the temperature sensor 20. The stator includes at least one electrical conductor 30. The conductor end 31 of the first electrical conductor 30 of the at least one electrical conductor 30 is inserted into the clamping space 120 as a temperature sensing target, and the temperature sensor 20 is inserted into and fixed in the accommodating space 130. The conductor end 31 of the first electrical conductor 30 is provided with a chamfer so as to cooperate with the anti-mistake inclined plate 114 of the spring clip 10 to prevent installation in the wrong direction. The conductor end 31 of the first electrical conductor 30 is provided with a limiting groove 311 so as to cooperate with the spring piece 124 of the spring clip 10 to limit the conductor end 31.
