[0004] Based on the above materials, it can be seen that automobile sensors in the prior art generally only use one temperature sensing element to measure temperature. However, in actual use, a single temperature sensing element is prone to measurement errors (such as aging damage or dirt adhesion), causing abnormal control of related parts of the automobile. Utility Model Content

[0005] The utility model aims to provide a composite automobile temperature sensor which is easy to assemble, so as to solve the problem of measurement error of a single temperature sensing element mentioned in the background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a composite automobile temperature sensor that is easy to assemble, comprising a fixed base plate fixedly installed inside the automobile by bolts, a sensor housing with a built-in control circuit installed above the fixed base plate, and further comprising:

[0007] A thermocouple temperature measuring probe is fixedly installed on the left outer surface of the sensor housing, and a receiving groove is provided on the left upper surface of the sensor housing, and a composite sensor matching the temperature measuring probe is installed inside the receiving groove, and an infrared probe for temperature measurement is arranged above the composite sensor;

[0008] The sensor housing is provided with positioning grooves at both the front and rear sides, and the positioning grooves correspond to positioning columns fixedly mounted on the upper surface of the fixed bottom plate, and a quick release mechanism is provided between the sensor housing and the fixed bottom plate.

[0009] Preferably, the quick-release mechanism comprises a fixing plate fixedly mounted on the upper surface of the fixing bottom plate, and a connecting rod is rotatably mounted on the outer portion of the upper end of the fixing plate.

[0010] Preferably, a fixing clip in a "7"-shaped structure is rotatably mounted on the upper end of the connecting rod, and the fixing clip and the sensor housing are engaged with each other.

[0011] Preferably, a connecting spring is fixedly installed between the inner side of the connecting rod and the fixing plate, and a rubber shock-absorbing pad corresponding to the sensor housing is fixedly installed on the upper surface of the fixing base plate.

[0012] Preferably, mounting blocks are fixedly mounted on the outer surfaces of the front and rear sides of the composite sensor, and a sliding disassembly and installation structure is formed between the mounting blocks and the mounting grooves provided on the inner wall of the accommodating groove.

[0013] Preferably, an adsorption magnetic block for adsorbing and fixing the composite sensor is fixedly installed on the lower surface of the interior of the accommodating groove, and a first contact piece is connected to the exterior of the rear side of the composite sensor by means of a wire.

[0014] Preferably, the first contact piece is in corresponding contact and conduction with a second contact piece fixedly installed on the inner wall of the accommodating groove, and a supporting piece is fixedly installed between the first contact piece and the composite sensor, and the supporting piece is configured as an elastic thin metal sheet structure.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the composite automobile temperature sensor which is easy to assemble adopts a new structural design, and its specific contents are as follows:

[0016] 1. The thermocouple temperature measuring probe outside the sensor housing is used as the main temperature sensing element to measure the temperature of the surrounding environment. At the same time, the composite sensor inside the accommodating tank uses the infrared probe above to assist in measuring the surrounding temperature, so that the whole forms a composite structure. The combination of the two can achieve higher accuracy;

[0017] Furthermore, the sensor housing and the fixed base plate are connected by a snap-fit ​​connection instead of the traditional bolted connection. When disassembling and assembling it, it is only necessary to move the fixing clip, making the overall disassembly and assembly operation more convenient, and convenient for the staff to disassemble and repair;

[0018] Furthermore, when the sensor housing is installed, the engagement between the positioning groove and the positioning column is utilized to achieve the purpose of positioning and avoid installation misalignment.

[0019] 2. The composite sensor is installed in the receiving groove above the sensor housing. The two are initially fixed by the engagement between the mounting block and the mounting groove, and then fixed by the magnetic adsorption of the adsorption magnetic block. This structure allows the composite sensor to be removed from the sensor housing for inspection;

[0020] Furthermore, the composite sensor and the sensor housing are connected by contact between the first contact piece and the second contact piece, which reduces the wiring harness connection between the two, making the device as a whole neater and simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] When using the device, first use bolts to install the fixed base plate 1 at the specified position in the car, then turn on the power of the entire device. When the device is working, the thermocouple temperature measuring probe 3 on the side of the sensor housing 2 is used to sense the ambient temperature. At the same time, the infrared probe 6 above the composite sensor 5 is turned on to assist in detecting the ambient temperature. The temperatures measured by both are fed back to the control computer, and after analysis and correction, more accurate data is obtained.

[0032] Example 2: Please refer to Figure 2-Figure 3 In order to achieve the purpose of quick installation of the device, the present embodiment provides the following technical solutions, which specifically disclose: positioning grooves 7 are provided on the front and rear sides of the sensor housing 2, and the positioning grooves 7 correspond to the positioning columns 8 fixedly installed on the upper surface of the fixed base plate 1, and a quick release mechanism is provided between the sensor housing 2 and the fixed base plate 1, and the quick release mechanism includes a fixing plate 9 fixedly installed on the upper surface of the fixed base plate 1, and a connecting rod 10 is rotatably installed on the upper end of the fixing plate 9, and a fixing clip 11 with a "7"-shaped structure is rotatably installed on the upper end of the connecting rod 10, and the fixing clip 11 and the sensor housing 2 are engaged with each other, a connecting spring 12 is fixedly installed between the inner side of the connecting rod 10 and the fixing plate 9, and a rubber shock-absorbing pad 101 corresponding to the sensor housing 2 is fixedly installed on the upper surface of the fixed base plate 1.

[0033] When the sensor housing 2 is disassembled for maintenance and then installed again, first push the fixing clip 11 outward, and then place the sensor housing 2 above the fixing base plate 1 (the fixing base plate 1 does not need to be disassembled during the disassembly and maintenance process). At this time, the sensor housing 2 is positioned by utilizing the cooperation between the positioning groove 7 and the positioning column 8. After it is placed in place, release the fixing clip 11, and pull the connecting rod 10 under the elastic pulling action of the connecting spring 12. Finally, under the action of the connecting rod 10, the fixing clip 11 clamps and fixes the sensor housing 2. No bolts are required to fix it during this process, thereby achieving the purpose of quick installation.

After the fixation is completed, the first contact piece 16 on the rear side of the composite sensor 5 is in contact with the second contact piece 18 on the inner wall of the receiving groove 4. This structure does not require the use of a wiring harness connection, and the overall structure is simpler. In addition, the support piece 17 on the rear side of the first contact piece 16 uses its own elasticity to push it to maintain contact with the second contact piece 18.
