With increasingly stringent environmental standards, especially requirements for automobile exhaust emissions, exhaust temperature monitoring has become a key technology. By measuring the temperature within the exhaust system, this sensor helps control engine combustion efficiency, reduce harmful emissions, ensure the normal operation of equipment, and extend its service life.

[0003] Existing technologies, such as the utility model patent with announcement number CN222346906U, disclose an automotive housing temperature sensor. This patent includes an aluminum alloy conductive component connected to the automotive housing, which has a bonding piece and a fixing part. One end of the bonding piece has an insertion hole. The bonding piece and the fixing part are integrally formed, and the fixing part is hollow and communicates with the insertion hole. In this utility model, a bolt is provided in the through hole, which can firmly fix the bonding piece to the front bumper of the car, thereby preventing it from falling off during long-distance travel. The wire is tightened and fixed by the binding port above the fixing part, thereby improving the fixing effect of the wire and the fixing part and improving the connection capability. The slot fits tightly with the protrusion on the front bumper, which can ensure the sensor probe fits the front bumper and improve the sensor probe's sensing and acquisition of the front bumper temperature.

[0004] In the prior art, exhaust temperature sensors are usually installed in critical parts of the exhaust system, such as exhaust pipes, exhaust manifolds or near turbochargers. Due to the high temperature at the exhaust port, the sensor and its connecting parts are often exposed to extreme thermal environments, which can easily lead to aging, melting or other thermal damage to the joints, thereby affecting the long-term stability and safety of the sensor.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 5 The present invention provides a snap-fit ​​exhaust temperature sensor housing, comprising: a connector 1, a connecting wire 2 installed on one side of the connector 1, a temperature sensing element 3 installed on the other side of the connecting wire 2, and an adjustment structure 4 provided on the side of the connector 1.

[0031] In the embodiments of this utility model, please refer to Figures 2 to 5The adjusting structure 4 includes a fixed frame 401, which is fixedly connected to both sides of the connector 1. An auxiliary groove 402 is provided on the upper surface of the fixed frame 401. A limit rod 403 is fixedly connected to the inner wall of the auxiliary groove 402. Two push blocks 404 are slidably connected to the inner wall of the auxiliary groove 402. The push blocks 404 and the limit rod 403 are slidably connected. Two first springs 405 are sleeved on the arc surface of the limit rod 403. The two ends of the first springs 405 are fixedly connected to the fixed frame 401 and the push blocks 404 respectively. Two insert plates 406 are fixedly connected to one side of the push blocks 404. Protective shells 407 are slidably connected to both sides of the connector 1. Fixed plates 408 are fixedly connected to both sides of the protective shells 407. Each side is provided with a connecting groove 409. Several fixing rods 410 are fixedly connected to the upper surface of the fixing frame 401. Connecting plates 411 are slidably connected to the arc surfaces of the fixing rods 410. A top block 413 is fixedly connected to the side of the connecting plates 411 that are close to each other. A limit block 412 is fixedly connected to the arc surface of the fixing rods 410. The size of the insert plate 406 and the connecting groove 409 are matched. A second spring 420 is sleeved on the arc surface of the fixing rod 410. The two ends of the second spring 420 are fixedly connected to the connecting plate 411 and the fixing frame 401, respectively. A guide block 418 is fixedly connected to one side of the insert plate 406. By setting the adjustment structure 4, the connector 1 can be protected to prevent the connector 1 from being directly exposed to excessive height. To prevent joint aging, melting, or other thermal damage at certain temperatures, thereby improving its stability and safety, the upper surface of the top block 413 is provided with anti-slip textures 414. These textures are evenly distributed on the top block 413, increasing its friction and preventing slippage when moving it. A soft pad 415, made of rubber, is fixedly connected to the lower surface of the limiting block 412. This prevents the connecting plate 411 from directly contacting the limiting block 412, thus preventing wear on the connecting plate 411. A roller 416 is rotatably connected to one side of the push block 404. The roller 416 reduces the friction between the push block 404 and the top block 413, allowing the push block 404 to move more smoothly. 04. For smoother movement, the first spring 405 has a bellows 421 fitted on its arc surface. The two ends of the bellows 421 are fixedly connected to the fixed frame 401 and the push block 404, respectively. The bellows 421 can protect the first spring 405 and prevent foreign objects from getting stuck inside the first spring 405. A magnet 419 is fixedly connected to one side of the protective shell 407. The magnet 419 can make the two protective shells 407 more stable and prevent the two protective shells 407 from separating. Both sides of the push block 404 are fixedly connected to ball bearings 417. The ball bearings 417 have a circular cross-section. The ball bearings 417 can reduce the friction of the push block 404, making the push block 404 move more smoothly in the auxiliary groove 402.

[0032] The working principle of the snap-on exhaust temperature sensor housing provided by this utility model is as follows: By setting the adjustment structure 4, the top block 413 is first moved with the help of the anti-slip texture 414, so that the top block 413 drives the connecting plate 411 to move on the fixed rod 410. When the connecting plate 411 moves, it also drives the second spring 420 to retract. At the same time, the limiting block 412 can limit the connecting plate 411. When the top block 413 moves, it drives the push block 404 to move in the auxiliary groove 402 of the fixed frame 401. At the same time, the push block 404 also moves on the limiting rod 403. When the push block 404 moves, it also drives the second spring 420 to retract. At this time, the two protective shells 407 are moved and put into the connector 1. When the protective shells 407 move, they also drive the fixed plate 408 to move, so that the fixed plate 408 is inserted into the fixed frame 401. Then, the top block 413 is released. Due to the action of the second spring 420, the top block 413 will move and then separate from the push block 404. Due to the action of the first spring 405, the top block 413 will move and then separate from the push block 404. The push block 404 moves, and during this movement, it also moves the insert plate 406, causing the insert plate 406 to drive the guide block 418 into the connecting groove 409 of the fixing plate 408. The anti-slip texture 414 increases the friction of the top block 413, preventing slippage when moving it. The soft pad 415 prevents the connecting plate 411 from directly contacting the limiting block 412, thus preventing wear on the connecting plate 411. The roller 416... To reduce the friction between the push block 404 and the top block 413, making the push block 404 move more smoothly, the bellows 421 can protect the first spring 405 to prevent foreign objects from getting stuck inside the first spring 405, the magnet 419 can make the two protective shells 407 more stable and prevent the two protective shells 407 from separating, and the ball bearing 417 can reduce the friction of the push block 404, making the push block 404 move more smoothly in the auxiliary groove 402.

[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
