Abstract
Description
Technical Field
[0001] This application relates to the field of temperature detection technology, and in particular to a mounting structure for a temperature sensor. Background Technology
[0002] In existing technologies, when the temperature of a heat-generating element (such as a resistor) driving a product needs to be detected, a temperature sensor is typically placed on the surface of the resistor. The conventional method is to fix the temperature sensor to the surface of the resistor with glue.
[0003] However, during the development of this application, the applicant discovered that due to the thermal resistance of the adhesive, there would be a certain temperature difference, affecting the test results. Furthermore, the adhesive strength of the adhesive is significantly reduced in high-temperature or humid environments (for example, the adhesive is prone to failure over time), causing the temperature sensor to detach and malfunction. Additionally, when repair or replacement is required, the adhesive must first be removed, and then reapplied during installation, which is inconvenient. Utility Model Content

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a temperature sensor mounting structure for fixing the temperature sensor to a mounting surface. The temperature sensor mounting structure includes a clamping member and a locking member. The clamping member includes a pressing part and a fixing part connected to each other. One side of the pressing part is provided with a limiting groove for accommodating the temperature sensor. The locking member is connected to the fixing part and is used to lock the clamping member to the mounting surface, so that the temperature sensor in the limiting groove is pressed against the mounting surface.

[0008] In one or more of the above optional embodiments, a guide structure is provided at the opening of the limiting groove, the guide structure being used to guide the temperature sensor during installation.
[0009] In one or more of the above optional embodiments, the fixing part includes a connecting plate and a fixing plate, the fixing plate is parallel to the pressing plate, the connecting plate is connected between the fixing plate and the pressing plate, and the locking member is connected to the fixing plate.
[0010] In one or more of the above optional embodiments, the fixing plate and the pressing plate are respectively connected to opposite ends of the connecting plate, and the connecting plate is perpendicular to the fixing plate and the pressing plate.
[0011] In one or more of the above optional embodiments, the width of the limiting plate is smaller than the width of the pressing plate along the width direction of the limiting plate, and the limiting plate is disposed on the side of the pressing plate close to the fixing plate; wherein, the width direction, the length direction, and the height direction of the limiting plate are mutually perpendicular to each other.
[0012] In one or more of the above optional embodiments, the number of locking elements is at least one; the fixing plate is provided with at least one locking hole, and each locking element passes through a corresponding locking hole.

The term "vertical" and similar expressions used in this specification are for illustrative purposes only.
[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.

[0021] Unless otherwise specified, the term "multiple" in this application refers to two or more.
[0022] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0023] Please see Figure 1 and Figure 2 , Figure 1 A perspective view of the temperature sensor mounting structure 1 in an embodiment of this application is shown. Figure 2 An exploded view of the mounting structure 1 for the temperature sensor is shown.
[0024] This application provides a mounting structure 1 for a temperature sensor, used to fix a temperature sensor 2 to a mounting surface. Figure 1 and Figure 2 The structure shown is illustrated by example. The temperature sensor 2 is fixed to the heating element 3 on the mounting plate 4 so that the temperature sensor 2 and the heating element 3 are in direct contact, avoiding the influence of glue on the detection results, thereby enabling accurate temperature measurement.
[0025] In some embodiments, the heating element 3 is fixed to the mounting plate 4 by fasteners 5, and the temperature sensor 2 is disposed on the side of the heating element 3 facing away from the mounting plate 4. The mounting surface includes a first mounting surface and a second mounting surface. The side of the heating element 3 facing the temperature sensor 2 is the first mounting surface, and the side of the mounting plate 4 facing the heating element 3 is the second mounting surface. The first and second mounting surfaces are spaced apart along the height direction and are parallel to each other. The height direction refers to the direction in which the temperature sensor 2, the heating element 3, and the mounting plate 4 are sequentially arranged. One end of the mounting structure 1 fixes the temperature sensor 2 to the first mounting surface, and the other end of the mounting structure 1 connects to the second mounting surface, thereby fixing the temperature sensor 2 to the heating element 3.
[0026] It is understood that in some other embodiments, the mounting surface may include only the first mounting surface or the second mounting surface, or the first mounting surface and the second mounting surface may be located on the same plane, or the first mounting surface and the second mounting surface may not be arranged in parallel, and none of these are limited here.
[0027] In some embodiments, the heating element 3 is fixedly mounted on the mounting plate 4 of the driving product by fasteners 5. For example, the fastener 5 is a bolt. The heating element 3 has a first mounting hole 301, and the mounting plate 4 has a fixing hole 401. The bolt passes through the first mounting hole 301 and the fixing hole 401 in sequence and is tightened to achieve a fixed connection between the heating element 3 and the mounting plate 4. It can be understood that the fixing hole 401 is a threaded hole. It should be noted that the heating element 3 includes, but is not limited to, a resistor. The following example illustrates the mounting surface, which includes the first mounting surface on the heating element 3 and the second mounting surface on the mounting plate 4.
[0028] In some embodiments, combined with Figure 3The temperature sensor mounting structure 1 includes a clamping member 10 and a locking member 20. The clamping member 10 includes a pressing part 110 and a fixing part 120 connected to each other. One side of the pressing part 110 is provided with a limiting groove 111 for receiving the temperature sensor 2. The locking member 20 is connected to the fixing part 120 and is used to lock the clamping member 10 to the mounting plate 4, so that the temperature sensor 2 in the limiting groove 111 is pressed against the mounting surface (the first mounting surface on the heating element 3).
[0029] In some embodiments, the pressing part 110 includes a pressing plate 112 and a limiting plate 113. The limiting plate 113 is disposed on one side of the pressing plate 112, that is, the limiting plate 113 extends from one side of the pressing plate 112 toward the direction close to the heating element 3. The limiting groove 111 is disposed on the limiting plate 113, and the fixing part 120 is connected to the pressing plate 112.
[0030] For ease of explanation, let x be the length direction of the limiting plate 113, y be the width direction of the limiting plate 113, and z be the height direction of the limiting plate 113. The length direction x, the width direction y, and the height direction z of the limiting plate 113 are all perpendicular to each other. The height direction z of the limiting plate 113 is the direction in which the limiting plate 113 faces the pressing plate 112.
[0031] In some embodiments, along the height direction z of the limiting plate 113, the limiting groove 111 penetrates the limiting plate 113, that is, the limiting groove 111 is recessed from the limiting plate 113 toward the pressing plate 112, that is, the pressing plate 112 serves as the bottom of the limiting groove 111, and the limiting plate 113 serves as the side of the limiting groove 111.
[0032] In some embodiments, the width of the limiting plate 113 is smaller than the width of the pressing plate 112 along the width direction y of the limiting plate 113, which is beneficial for the processing of the fixing part 120.
[0033] In some embodiments, the first end of the limiting plate 113 is flush with the first end of the pressing plate 112, and the second end of the limiting plate 113 is misaligned with the second end of the pressing plate 112.
[0034] In some embodiments, along the length direction x of the limiting plate 113, one end of the limiting groove 111 is provided with an opening, that is, the limiting groove 111 is a U-shaped groove. On the one hand, it facilitates the installation of the temperature sensor 2, and on the other hand, the opening of the U-shaped groove allows the lead wire of the temperature sensor 2 to pass through. At the same time, the opening of the U-shaped groove allows the contact between the temperature sensor 2 and the mounting surface to be clearly observed.
[0035] In some embodiments, the opening of the limiting groove 113 is provided with a guide structure 114, which is used to guide the temperature sensor 2 during installation.
[0036] In some embodiments, the guide structure 114 is an inclined slope.
[0037] In some embodiments, the pressing plate 112 is parallel to the mounting surface (first mounting surface or second mounting surface). Furthermore, the surface of the limiting groove 111 facing the heating element 3 is a plane to achieve a tight fit between the planes, which is beneficial to increase the contact area between the temperature sensor 2 and the first mounting surface.
[0038] In some embodiments, such as Figure 4 and Figure 5 As shown, the fixing part 120 includes a connecting plate 121 and a fixing plate 122. The connecting plate 121 extends from one end of the pressing plate 112 of the pressing part 110 in a direction close to the heating element 3. The fixing plate 122 extends from the end of the connecting plate 121 away from the pressing part 110 in a direction away from the heating element 3. That is, the connecting plate 121 connects the fixing plate 122 and the pressing plate 112. The limiting plate 113 is provided on the side of the pressing plate 112 close to the fixing plate 122.
[0039] In some embodiments, the fixing plate 122 and the pressing plate 112 are respectively connected to the opposite ends of the connecting plate 121, the included angle between the connecting plate 121 and the pressing plate 112 of the pressing part 110 is 85°-95°, and the included angle between the fixing plate 122 and the connecting plate 121 is 85°-95°.
[0040] In some embodiments, the connecting plate 121 is perpendicular to both the fixing plate 122 and the pressing plate 112. That is, the fixing plate 122 is parallel to the pressing plate 112, and the locking member 20 is connected to the fixing plate 122.
[0041] In some embodiments, the pressing plate 112, the connecting plate 121, and the fixing plate 122 are integrally formed.
[0042] In some embodiments, the clamping member 10 is made of an insulating and heat-resistant material.
[0043] In some embodiments, the clamping member 10 is composed of at least one insulating material selected from bakelite, plastic, fiberglass, ceramic, silicone rubber, etc.
[0044] In some embodiments, a buffer (not shown) is provided in the limiting groove 111. The buffer is located between the pressing plate 112 of the pressing part 110 and the temperature sensor 2, and the buffer is used to abut against the temperature sensor 2.
[0045] In some embodiments, the buffer is a cushioning pad, that is, the buffer is sheet-like.
[0046] In some embodiments, the shape of the buffer is adapted to the limiting groove 111. That is, the buffer is provided with a receiving groove for accommodating the temperature sensor 2, so that the gap between the temperature sensor 2 and the limiting groove 111 is filled by the buffer.
[0047] By incorporating a buffer, the pressure from the pressing part 110 is transmitted to the buffer, which in turn presses the temperature sensor 2 against the first mounting surface through the elasticity of the buffer. Furthermore, the buffer is made of a relatively soft material, which prevents hard contact between the pressing plate 112 and the temperature sensor 2, providing mechanical force cushioning.
[0048] In some embodiments, the sum of the thicknesses of the temperature sensor 2 and the buffer is greater than or equal to the depth of the limiting groove 111 in the direction extending from the heating element 3 toward the pressing part 110.
[0049] It is understood that when the buffer has a receiving groove, the thickness of the buffer refers to the thickness of the bottom of the receiving groove.
[0050] In some embodiments, the number of locking members 20 is at least one. For example, the locking member 20 is a fastening screw, the fixing plate 122 is provided with at least one locking hole 1221, the mounting plate 4 is provided with at least one second mounting hole 402, the locking hole 1221 and the second mounting hole 402 correspond one-to-one, and each locking member 20 is tightened after passing through the corresponding locking hole 1221 and the second mounting hole 402.
[0051] In practice, the heating element is first fixed to the mounting plate, then the locking part is pre-installed in the locking hole of the clamping part (the locking part is not tightened), then the temperature sensor is inserted into the limiting groove, and finally the locking part is tightened to achieve the pressing of the temperature sensor with the mounting surface.
[0052] The temperature sensor mounting structure provided in this application reduces the risk of sensor failure in high-temperature or humid environments by using clamping and locking components instead of adhesive. Furthermore, the clamping force provided by the locking components ensures direct contact between the temperature sensor and the first mounting surface, improving temperature detection accuracy. Additionally, the locking components facilitate easy assembly and disassembly.
[0053] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application's specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
