[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. It is the primary link in realizing automatic detection and automatic control. Sensors are widely used in many modern technological fields, such as industrial production, automated process control, environmental monitoring, medical equipment, smart homes, etc. Through sensors, people can obtain various physical quantities, chemical quantities, biomass and other information, and convert them into processable electrical signals, thereby realizing the monitoring, control and optimization of various parameters and states.

[0003] After long-term use, the brake pads inside the current passenger car calipers will continue to wear out. If the brake pads are worn to a dangerous degree and are not replaced in time, it will greatly increase the driving risk. The brake pads will also generate a lot of heat during friction, which will damage the braking system. Most current cars will install wear sensors and temperature sensors on the calipers separately, which makes the structure of the braking system more complicated and increases the difficulty of design and installation. At the same time, the two independent systems also increase the time for maintenance, calibration and replacement of parts, further increasing the cost of using the vehicle. Utility Model Content

[0029] The detection mechanism 2 includes a shell 201, the outer wall of the shell 201 is provided with a circular groove 202, the outer wall of the shell 201 is provided with two first threaded holes 203, the inner walls of the two first threaded holes 203 are both threadedly connected with first fixing screws 204, the outer wall of the shell 201 is provided with two second mounting grooves 205, the inner walls of the two second mounting grooves 205 are both fixedly installed with elastic retaining springs 206, the outer wall of the shell 201 is fixedly installed with two fixing blocks 207, the outer walls of the two fixing blocks 207 are both provided with a set of second threaded holes 20 8.

The outer wall of the two connecting brackets 214 is provided with a third threaded hole 215. The inner surface walls of the two third threaded holes 215 are both threadedly connected with third fixing screws 216, and the outer wall sides of the two third fixing screws 216 are both fixedly installed with second extrusion plates 217. The inner surface wall of one of the two first mounting holes 211 is movably inserted with a wear sensor wire 218, and the outer surface wall of the wear sensor wire 218 is movably inserted inside the other of the two first mounting holes 211. The inner surface wall of the circular groove 202 is movably inserted with a wear sensor wire 218. A group of dampers 219 are fixedly installed on the top of the housing 201. The housing A group of springs 220 are fixedly installed on the top of 201, a metal sleeve 221 is fixedly installed between the tops of the group of springs 220, and the bottom of the metal sleeve 221 is fixedly connected to the telescopic end of a group of dampers 219, a third mounting hole 222 is opened on the top of the metal sleeve 221, a temperature sensor probe 223 is fixedly inserted into the inner surface wall of the third mounting hole 222, the output end of the temperature sensor probe 223 is fixedly connected to a temperature sensor wire 224, and the outer surface wall of the temperature sensor wire 224 is fixedly inserted into the inside of the second mounting hole 212.

[0030] The effect achieved by the entire embodiment 1 is that the two elastic retaining springs 206 on the housing 201 can quickly fix the position of the housing 201, and then the second fixing screw 209 and the third fixing screw 216 can be rotated to drive the first extrusion plate 210 and the second extrusion plate 217 to move respectively, so as to further fix the position of the housing 201, so as to prevent it from being displaced or falling off during the driving and braking of the car, thereby affecting the monitoring effect and threatening the driving safety of the car.

[0031] Embodiment 2, as Figure 2-Figure 6 As shown, the fixing mechanism 1 includes a base plate 101, the inner wall of the base plate 101 is provided with two first mounting grooves 102, a brake pad 103 is fixedly mounted on the top of the base plate 101, the top of the base plate 101 is in contact with the bottom of the two groups of first extrusion plates 210, the bottom of the base plate 101 is in contact with the top of the two groups of second extrusion plates 217, and the inner walls of the two first mounting grooves 102 are movably embedded with the outer wall of the elastic retaining spring 206.

[0032] The effect achieved by the entire embodiment 2 is that when the car needs to brake, the base plate 101 will drive the brake pad 103 to move forward and contact with the brake disc to generate friction, so that the car can brake. The first installation groove 102 on the base plate 101 can facilitate the disassembly and installation of the sensor, reducing the time and labor cost of installing the sensor.

[0033] Working principle: first insert the two elastic retaining springs 206 inside the shell 201 into the bottom plate 101 to fix the shell 201 on the bottom plate 101, then rotate the second fixing screw 209 first, the second fixing screw 209 will rotate and descend inside the second threaded hole 208 inside the fixing block 207, driving the first extrusion plate 210 to start to descend and contact the top of the bottom plate 101, and then adjust the position of the connecting bracket 214 through the fixing rod 213, and screw the third fixing screw 216, so that the third fixing screw 216 drives the second extrusion plate 217 to start to rotate and rise inside the connecting bracket 214, and contact the bottom of the bottom plate 101, the two extrusion plates cooperate with each other to further fix the position of the shell 201, and when the brake pad 103 is working, it will generate intense friction with the brake disc, causing the temperature of the brake pad 103 to continue to rise, and the temperature sensor probe 223 that is in contact with the brake pad 103 can detect the temperature of the brake pad 103 in time, and The data is uploaded to the car owner through the temperature sensor wire 224, so that the car owner can take corresponding measures when the temperature of the brake pad 103 is too high to avoid safety hazards caused by high temperature damage to the brake system. A set of dampers 219 and springs 220 will drive the temperature sensor probe 223 to move to avoid damage to the temperature sensor probe 223 due to vibration when the brake pad 103 is working. The brake pad 103 will gradually become thinner after long-term use. At this time, the wear sensor wire 218 will contact the top brake disc and be worn off by the brake disc. The wear sensor will issue an alarm to remind people to replace the brake pad 103 in time. After the wear sensor wire 218 is worn off, people can rotate the first fixing screw 204 to pull it out, and then insert the intact wear sensor wire 218 into the circular groove 202 and the two first mounting holes 211. Finally, rotate the first fixing screw 204 in the opposite direction to fix the wear sensor wire 218, thereby increasing the service life of the sensor and reducing the replacement cost.
