[0002] With the rapid development of new energy vehicles, high-power engines, fast charging, and supercharging technologies are constantly being upgraded. This leads to more frequent high-temperature and overheating situations, posing certain safety risks. Therefore, temperature sensors are installed on motors and charging systems to monitor the temperature of corresponding parts and respond promptly to prevent safety accidents caused by overheating. One feasible method is to clamp the temperature sensor onto the corresponding component using a clamping device. However, due to the wide variety of new energy vehicles and numerous manufacturers, the structures of the temperature-measuring components can differ between different companies and models. This necessitates designing custom clamping devices based on specific requirements, thus increasing the manufacturing cost of the temperature sensor. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This utility model provides a universal mounting temperature sensor, including a sensor body. In one embodiment, such as... Figure 4 The aforementioned sensor body includes a housing 11 and a temperature-sensing element 13 encapsulated within the housing 11. The temperature-sensing element 13 is connectable to a wire 12, which extends from the housing 11. The temperature-sensing element 13 can be a thermistor, platinum resistance thermometer, or other temperature-sensing element. Optionally, the temperature-sensing element 13 and the wire 12 are welded together using a combination of resistance welding and laser welding to form a welded semi-finished product, which is then encapsulated in the housing 11.

[0022] Preferably, the sensor body is encapsulated in a plastic encapsulation manner. After the encapsulation shell 11 covers the temperature sensing head of the welded semi-finished product (completely covering the temperature sensing element 13), the encapsulation shell 11 can be used to complete the plastic encapsulation of the welded semi-finished product by high-temperature melting.

[0023] Optionally, the aforementioned encapsulation housing 11 is a fluoroplastic housing, and the aforementioned sensor body is correspondingly a fluoroplastic encapsulated temperature sensor. Further, the encapsulation housing 11 includes an inner tube and an outer tube. Under high temperature conditions, the inner tube melts into a molten state, serving a sealing function, while the outer tube shrinks, serving a shaping and insulating protection function.

[0024] In one embodiment, such as Figure 1 and Figure 4 The aforementioned encapsulation housing 11 is rectangular, which facilitates clamping by the clamping structure; however, it is not limited to this shape of encapsulation housing 11, and cylindrical or irregularly shaped encapsulation housing 11 is also applicable to this embodiment.

[0025] Furthermore, such as Figures 1-3 The aforementioned general-purpose mounting temperature sensor also includes a C-shaped clamp 3 suitable for clamping onto the component to be measured. The C-shaped clamp 3 is a deformable clamp so that its slot width is variable. The C-shaped clamp 3 includes two clamping arms 31 and a connecting plate 32 connecting the two clamping arms 31. One of the clamping arms 31 is a mounting clamping arm 310 with a clamping structure on its outer surface. The sensor body is clamped on the mounting clamping arm 310 by the clamping structure.

[0026] In the initial state, the C-shaped clamp 3 has an initial slot width. When the two clamping arms 31 are squeezed, the distance between the slot ends of the two clamping arms 31 will increase, and the slot width of the C-shaped clamp 3 will increase accordingly.

[0027] Preferably, the C-shaped clamping plate 3 is a one-piece molded structure, for example, it is formed by bending a steel plate to form two clamping arms 31, that is, the dihedral angle between the two clamping arms 31 and the connecting plate 32 is formed by bending. Based on the deformable characteristics of the clamping plate itself, especially the deformable characteristics of the bending point, the groove width of the C-shaped clamping plate 3 is variable, and the distance between the two clamping arms 31 is variable.

[0028] Based on the above design, and taking advantage of the deformable characteristics of the C-shaped clamp 3, it can be clamped onto components of various shapes and sizes, greatly improving the applicability of the temperature sensor and expanding its application scenarios, thereby improving the versatility of the temperature sensor; moreover, it can ensure the clamping stability of the two clamping arms 31 on the component under test, thereby improving the installation reliability of the temperature sensor.

[0029] In one embodiment, such as Figures 1-3 From the groove towards the connecting plate 32, the distance between the two clamping arms 31 gradually increases, resulting in a better clamping effect on the component to be tested, and further improving the clamping versatility of the C-shaped clamping plate 3.

[0030] In one embodiment, such as Figure 3 The dihedral angle between the mounting arm 310 and the connecting plate 32 is smaller than the dihedral angle between the other arm 31 and the connecting plate 32. This ensures that the mounting arm 310 is more closely attached to the component to be tested, thereby improving the detection reliability of the sensor body.

[0031] Understandably, the aforementioned C-shaped clamp 3 is roughly configured as a dovetail clamp with the dovetail handle removed. Based on the deformability of the C-shaped clamp 3, when the C-shaped clamp 3 is pushed along the surface of the component to be tested by external force, the component to be tested can be stuck in the C-shaped clamp 3 and held by the C-shaped clamp 3.

[0032] In one embodiment, such as Figures 1-3 The slotted ends of the two clamping arms 31 are bent inward to form stop plates 311; the stop plates 311 can abut against the corresponding clamping arms 31; by forming the stop plates 311, on the one hand, they can play a stopping role and prevent the C-shaped clamping plate 3 from detaching from the component to be tested; on the other hand, they can increase the structural strength and rigidity of the clamping arms 31 at the slot, thereby improving the clamping reliability of the component to be tested.

[0033] In one embodiment, such as Figure 1 and Figure 2The clamping structure includes a first pressing part 21 and a second pressing part 22. The first pressing part 21 and the second pressing part 22 are both connected to the mounting clamping arm 310. The sensor body is pressed and fixedly connected to the first pressing part 21 and the second pressing part 22 respectively.

[0034] In this embodiment, the sensor body is pressed and fixed by the first pressing part 21 and the second pressing part 22, realizing the dual-position fixation of the sensor body, which is stable and reliable, effectively preventing the sensor body from falling off, ensuring the structural stability of the temperature sensor, and thus improving its detection accuracy.

[0035] The first crimping portion 21 and the second crimping portion 22 are arranged sequentially along a predetermined direction, that is, the first crimping portion 21 and the second crimping portion 22 define the mounting direction of the sensor body. This mounting direction can be such that the sensor body has a large temperature sensing area. When the encapsulation housing 11 is rectangular, preferably, the first crimping portion 21 and the second crimping portion 22 are arranged sequentially along the length of the encapsulation housing 11, so that the head and tail of the encapsulation housing 11 can be fixed by the first crimping portion 21 and the second crimping portion 22 respectively.

[0036] Optionally, such as Figure 1 and Figure 2 The first pressing part 21 and the second pressing part 22 are arranged in a direction perpendicular to the groove depth direction of the C-shaped clamp 3. This design can avoid interference between the sensor body and other structural components around the component to be measured when the C-shaped clamp 3 is installed, thus facilitating the installation of the temperature sensor.

[0037] Optionally, such as Figure 1 and Figure 2 The two longitudinal ends of the mounting clamping arm 310 extend outward to form extension plates 33, wherein the longitudinal direction of the mounting clamping arm 310 is parallel to the groove length direction of the C-shaped clamping plate 3; the first pressing part 21 and the second pressing part 22 are respectively provided on the two extension plates 33.

[0038] In one embodiment, such as Figures 1-3 The first pressing part 21 includes two first pressing plates 211. Both first pressing plates 211 are deformable plates and are disposed opposite to each other on the mounting clamp arm 310. The two first pressing plates 211 are respectively pressed onto the housing head of the sensor body and the housing head is held tightly by the two plates.

[0039] The deformable nature of the first pressing plate 211 facilitates the assembly and disassembly of the sensor body in the first pressing part 21, and also allows for adjustment of the pressing force on the head of the housing, thus achieving reliable fixation of the sensor body.

[0040] In the structure described above with extension plate 33, two first pressing plates 211 can be disposed on the extension plate 33 on the corresponding side.

[0041] Furthermore, such as Figures 1-3 The housing head includes two opposing first head sidewalls and two opposing second head sidewalls; the first pressing plate 211 includes a first constraint plate segment 2111 and a first pressing plate segment 2112, the two ends of the first constraint plate segment 2111 are respectively connected to the mounting clamp arm 310 and the first pressing plate segment 2112 through a transition plate segment 2113, the transition plate segment 2113 is a deformable plate segment; the two first constraint plate segments 2111 abut against the two first head sidewalls respectively, and the two first pressing plate segments 2112 press against one of the second head sidewalls and make the other second head sidewall abut against the mounting clamp arm 310.

[0042] The first pressing plate 211 can be made of metal, which can also improve the heat conduction effect to a certain extent; the first constraint plate segment 2111 and the first pressing plate segment 2112 can be made of rigid plates or metal plates with a certain plastic deformation capacity (the plastic deformation capacity is weaker than that of the transition plate segment 2113); the transition plate segment 2113 is preferably made of a plate with a certain plastic deformation capacity, including but not limited to metal plates with plastic deformation capacity or high-performance plastic plates.

[0043] In one embodiment, such as Figure 1 and Figure 2 The second pressing part 22 includes two second pressing plates 221. Both second pressing plates 221 are deformable plates and are disposed opposite to each other on the mounting clamp arm 310. The two second pressing plates 221 are respectively pressed onto the tail of the housing of the sensor body and the two hold the tail of the housing tightly.

[0044] The deformable nature of the second pressing plate 221 facilitates the assembly and disassembly of the sensor body in the second pressing part 22, and also allows for adjustment of the clamping force on the tail of the housing, thus achieving reliable fixation of the sensor body.

[0045] In the structure described above with extension plate 33, two second pressing plates 221 can be disposed on the extension plate 33 on the corresponding side.

[0046] Furthermore, such as Figure 1 and Figure 2The tail portion of the housing includes two opposing first tail sidewalls and two opposing second tail sidewalls; the second pressing plate 221 includes a second constraint plate segment (shown in the figure, not labeled) and a second pressing plate segment (shown in the figure, not labeled), the two ends of the second constraint plate segment are respectively connected to the mounting clamp arm 310 and the second pressing plate segment through a transition plate segment (shown in the figure, not labeled), the transition plate segment is a deformable plate segment; the two second constraint plate segments abut against the two first tail sidewalls respectively, and the two second pressing plate segments press against one of the second tail sidewalls and make the other second tail sidewall abut against the mounting clamp arm 310.

[0047] The second pressing plate 221 can be made of metal, which can also improve the heat conduction effect to a certain extent. The second constraint plate segment and the second pressing plate segment can be made of rigid plate or metal plate with a certain plastic deformation capacity (the plastic deformation capacity is weaker than that of the transition plate segment). The transition plate segment preferably uses a plate with a certain plastic deformation capacity, including but not limited to using a metal plate with plastic deformation capacity or a high-performance plastic plate.

[0048] Based on the first crimping part 21 and the second crimping part 22 of the above structure, the sensor body can be fixed by crimping, which can improve the assembly efficiency of the temperature sensor.

[0049] In one embodiment, such as Figure 2 and Figure 3 The clamping structure further includes an end baffle 23, which is connected to the mounting arm 310, and the housing end of the sensor body abuts against the end baffle 23. In the structure with the extension plate 33 described above, the end baffle 23 can be disposed on the extension plate 33 on the corresponding side. Based on the end baffle 23, not only can the sensor body be positioned and installed, but also the installation stability and reliability of the sensor body can be further improved by the cooperation of the end baffle 23 with the first pressing part 21 and the second pressing part 22.

[0050] In another optional embodiment, the distance between the first crimping part 21 and the second crimping part 22 is adjustable. This structure can be applied to the installation of sensor bodies of different specifications, further improving the versatility of the temperature sensor.

[0051] Preferably, the mounting arm 310 is provided with multiple crimping part mounting positions, each crimping part mounting position is arranged in a straight line with the first crimping part 21, and the second crimping part 22 is selectively fixedly mounted on one of the crimping part mounting positions; in this way, the second crimping part 22 can be designed to also include a mounting plate, with two second crimping plates 221 respectively connected to the mounting plate (when the second crimping plate 221 includes a second constraint plate segment and a second crimping plate segment, the second constraint plate segment is connected to the mounting plate through a transition plate segment) and the three are connected to form a groove-shaped crimping part, which is fixedly mounted on one of the crimping part mounting positions by the mounting plate, so that the mounting position of the second crimping part 22 on the mounting arm 310 is adjustable, thereby making the distance between the first crimping part 21 and the second crimping part 22 adjustable.

[0052] The fixed connection between the second crimping part 22 and the crimping part mounting position includes, but is not limited to, detachable installation methods such as screw fixing and snap-fit ​​fixing. Taking screw fixing as an example, multiple first screw holes are sequentially provided on the mounting arm 310, and each first screw hole is sequentially provided along the longitudinal direction of the mounting arm 310, thereby forming multiple crimping part mounting positions; second screw holes are provided on the mounting plate, and by selectively aligning the second screw holes on the mounting plate with the first screw holes on the mounting arm 310 and fixing them with screws, the installation position of the second crimping part 22 on the mounting arm 310 can be adjusted.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
