[0031] The fixing member 4 is connected to the lower housing 1, and the two can be connected by threads. The circuit board 3 is clamped in the installation space by the fixing member 4, and the circuit board 3 is limited in the horizontal direction by the fixing member 4; the lower housing 1 and the upper housing 2 can be fixed by thread connection, so as to limit the vertical direction of the circuit board 3, so that the circuit board 3 is fixed in the installation space;

[0032] Through the above technical scheme, when the temperature-vibration integrated sensor is installed on the electromechanical equipment and works for a long time, it can prevent the circuit board 3 from shaking in the installation space, ensure its installation stability, and improve the accuracy of vibration detection; when monitoring the electromechanical equipment, it can realize early diagnosis of vibration faults of the electromechanical equipment and ensure the accuracy of the detection results.

[0033] like Figure 2 and Figure 5 As shown, in one embodiment, a first installation area 110 is provided on the lower shell 1, and a second installation area 210 is provided on the upper shell 2, and the first installation area 110 and the second installation area 210 form an installation space.

[0034] like Figure 2 As shown, the first installation area 110 is a hole arranged at the upper end of the lower housing 1. Figure 5 As shown, the second installation area 210 is a hole arranged at the lower end of the upper shell 2, and the lower shell 1 and the upper shell 2 are connected to form an installation space.

[0035] like Figure 3 As shown, in one embodiment, the fixing member 4 includes: two fixing bodies 410, the fixing bodies 410 include an arc-shaped clamping plate 411 and a bottom plate 412 arranged at the bottom of the arc-shaped clamping plate 411, and the bottom plate 412 is connected to the bottom surface of the first installation area 110; a clamping groove 420 is formed on the opposite side of the arc-shaped clamping plates 411 of the two fixing bodies 410, and the circuit board 3 is clamped and fixed in the clamping groove 420.

[0036] When installing the circuit board 3, the fixing member 4 can be placed in the first installation area 110 first, and then the circuit board 3 can be placed between the two fixing bodies 410. Then, the distance between the two fixing bodies 410 can be adjusted so that the two arc-shaped clamping plates 411 abut against the circuit board 3 to clamp the circuit board 3. Then, the bottom plate 412 of the fixing body 410 can be fixed to the bottom surface of the first installation area 110. The two can be fixed by means of threaded connection or clamping.

[0037] In addition, an elastic layer may be provided on the sides of the two arc-shaped clamping plates 411 in contact with the circuit board 3 , and an elastic layer may also be provided on the top surface of the second mounting area 210 in contact with the circuit board 3 , so as to better fix the circuit board 3 .

[0038] like Figure 2-Figure 4 As shown, a method of threaded connection between a bottom plate 412 and the bottom surface of the first installation area 110 is provided, the bottom plate 412 is provided with at least one long hole 413 , and a threaded hole 111 corresponding to the long hole 413 is provided on the bottom surface of the first installation area 110 .

The two fixing bodies 410 are respectively located on both sides of the limiting groove 112.

[0042] like Figure 2 As shown, in one embodiment, a stud 120 is provided at the bottom of the lower shell 1 .

[0043] The temperature-vibration integrated sensor can be connected to the electromechanical equipment by threaded connection or magnetic connection;

[0044] The electromechanical equipment is pre-equipped with screw holes corresponding to the studs 120, and the installation can be completed by directly screwing the studs 120 into the screw holes;

[0045] Or, if Figure 5-Figure 6 As shown, when there are no screw holes pre-set on the surface of the electromechanical equipment, the magnetic component 6 can be used for installation. Specifically, a screw hole threadedly connected to the stud 120 is provided on the magnetic component 6. The magnetic component 6 can be threadedly connected to the stud 120 first, with the surface with adsorption effect facing outward.

[0047] It also includes: a wireless communication module electrically connected to the MCU; the wireless communication module can adopt a WIFI module and a Bluetooth module, etc., for wireless transmission of data.

[0048] The temperature sensor 5 may be an infrared temperature sensor, and the vibration sensor may be a vibration chip for high-precision vibration monitoring;

[0049] The temperature sensor 5 transmits the acquired temperature data to the MCU, and the vibration sensor transmits the acquired vibration data to the MCU. The MCU processes the temperature data and vibration data, and then transmits them to the terminal device through the wireless communication module. The MCU and the temperature sensor 5, the vibration sensor and the wireless communication module realize the monitoring, analysis and data transmission of the temperature and vibration of the electromechanical equipment. The monitoring, analysis and transmission methods of the existing technology can be adopted, which will not be repeated here.

[0050] like Figure 2 and Figure 7 As shown, in one embodiment, a battery (not shown in the figure) is further provided in the installation space, and an electrical port 130 is provided on the outer side of the lower shell 1, and the battery is electrically connected to the MCU and the electrical port 130 respectively.

[0051] In this embodiment, the temperature-vibration integrated sensor can be powered by a battery, and the battery can be a lithium battery. The battery is electrically connected to the MCU and the power port 130 respectively, and the voltage output end of the battery is electrically connected to the voltage input end of the MCU; the battery can be set in the installation space;

[0052] The power port 130 is used to electrically connect to an external power source to charge the battery. The power port 130 can adopt a magnetic charging interface, or a conventional charging interface in the prior art, such as a type-c interface.

[0053] The temperature sensor 5 provides the following two installation methods:

[0054] The first one is that the temperature sensor 5 is arranged on the circuit board 3 .

[0055] The second is, Figure 3-5 As shown, the temperature sensor 5 is disposed in a stepped hole 140 of the lower housing 1 , and the stepped hole 140 is disposed at the bottom of the first mounting area 110 ;

[0056] The bottom plate 412 is provided with a through hole 414 through which the temperature sensor 5 can pass. A pressing block 415 is provided inside the through hole 414 . An elastic block 416 is provided on the bottom surface of the pressing block 415 . The elastic block 416 contacts the top surface of the temperature sensor 5 .

[0057] When the temperature-vibration integrated sensor is connected to the electromechanical device by threaded connection, in order to improve the accuracy of temperature detection of the electromechanical device, the temperature sensor 5 is as close to the inside of the electromechanical device as possible. Therefore, the probe of the temperature sensor 5 is inserted into the stepped hole 140, and the stepped hole 140 can extend into the stud 120. The mounting end of the temperature sensor 5 is located at the upper part of the stepped hole 140. The upper part of the stepped hole 140 is used for limiting. The lead of the temperature sensor 5 can pass through the stepped hole 140 and the through hole 414 to be electrically connected to the MCU (the electrical connection can be performed using a connecting terminal);

[0058] After the fixing body 410 is installed, the elastic block 416 can be elastically abutted against the top of the temperature sensor 5 through the pressing block 415 to ensure the stability of the connection of the temperature sensor 5; of course, the temperature sensor 5 can also be threadedly connected to the stepped hole 140.
