Technical Field

[0001] This utility model relates to the technical field of vehicle-mounted oxygen concentration monitoring devices, and in particular to a sensor device for vehicle-mounted oxygen concentration monitoring. Background Technology

[0002] As a key component in automotive emission control systems, oxygen sensors play a vital role in controlling vehicle exhaust emissions and reducing vehicle pollution. Therefore, it is necessary to design an on-board oxygen concentration monitoring sensor device.

[0003] Traditional vehicle-mounted oxygen concentration monitoring sensors are inconvenient to protect during use, and long-term use can damage the sensor's outer casing, reducing its lifespan. Therefore, it is necessary to design a vehicle-mounted oxygen concentration monitoring sensor device that can be easily protected. Utility Model Content

[0004] The purpose of this invention is to provide a sensor device for vehicle oxygen concentration monitoring, which solves the problem that existing vehicle oxygen concentration monitoring sensors are inconvenient to protect during use, and long-term use will cause damage to the sensor's outer shell and reduce its service life.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sensor device for monitoring vehicle oxygen concentration, including a mounting plate;

[0006] A monitoring component is provided on one side of the mounting plate. The monitoring component includes a monitoring box, a data monitoring module, a monitoring structure, and an oxygen concentration sensor. The monitoring box is fixed to one side of the mounting plate. The data monitoring module is installed on the outer wall of the monitoring box away from the mounting plate. The monitoring structure is provided inside the monitoring box. The oxygen concentration sensor is installed on the top of the monitoring box.

[0007] The monitoring box has a protective structure on its outside. The protective structure includes a protective cover, a reserved slot, fixing bolts, a mounting slot, mounting blocks, and a support plate. The protective cover is located on the outside of the monitoring box. The top of the protective cover has a reserved slot. The mounting blocks are evenly distributed on the side of the mounting plate near the protective cover. The interior of each mounting block has a mounting slot. The top of each mounting block has a fixing bolt. The bottom of the protective cover has a support plate.

[0008] The mounting plate is fixed with a mounting structure on the side away from the monitoring box.

[0009] Furthermore, the monitoring structure includes a circuit board, a data processing module, a microcontroller, and a data recording module. The circuit board is installed on one side inside the monitoring box, the data processing module is installed on one side of the top of the circuit board, the microcontroller is located below the data processing module, and the data recording module is located below the microcontroller.

[0010] Furthermore, the output terminal of the microcontroller is electrically connected to the input terminal of the data monitoring module, and the input terminal of the microcontroller is electrically connected to the output terminal of the oxygen concentration sensor.

[0011] Furthermore, one end of each mounting block is fixedly connected to the outer wall of the protective cover, and the mounting blocks are symmetrically distributed on both sides of the protective cover.

[0012] Furthermore, the mounting block and the mounting plate form a sliding structure through the mounting groove, the auxiliary cross section of the mounting block is designed in a "T" shape, and one side of the support plate and one side of the mounting plate are fixedly connected.

[0013] Furthermore, the mounting structure includes an adsorption plate, a connecting ring, a fixing ring, and a fixing plate. The fixing plate is fixed to the side of the mounting plate away from the monitoring box. A fixing ring is fixed to one side of the adsorption plate. A connecting ring is provided on the outer side of the fixing ring. An adsorption plate is fixed to one side of the connecting ring.

[0014] Furthermore, the main cross-section of the adsorption plate is trapezoidal, and the connecting ring and the fixing ring are threaded together.

[0015] The advantages of the vehicle-mounted oxygen concentration monitoring sensor device provided by this utility model are as follows:

[0016] By incorporating a protective structure, after the sensor is installed, the mounting blocks on both sides of the protective cover are inserted into the mounting grooves and slid downwards to fix the protective cover to one side of the mounting plate, protecting the monitoring component inside the protective cover. When the protective cover slides downwards, the limiting blocks fixed on both sides of its bottom end will engage with the limiting grooves on both sides of the top of the support plate when it slides to the bottom, preventing the protective cover from being restricted during use. Finally, the protective cover is fixed in place by fixing bolts, thus realizing the function of protecting the monitoring component and improving the service life of the vehicle oxygen concentration monitoring sensor device.

[0017] With an installation structure, one side of the adsorption plate is attached to the desired installation location, and pressing firmly will expel the air inside the adsorption plate. The sensor device is then adsorbed onto the desired installation location via the adsorption plate. During long-term use, if the adsorption effect of the adsorption plate decreases, the adsorption plate can be removed and replaced using the connecting ring or fixing ring, ensuring the stability of the device installation. This design enables the device to be easily adsorbed and installed, improving the convenience of using the vehicle-mounted oxygen concentration monitoring sensor device.

[0018] By incorporating a monitoring structure, an oxygen concentration sensor is used to monitor the concentration of medical oxygen in real time. A data processing module is used to receive and process the oxygen concentration data acquired by the sensor. A data monitoring module is used to display real-time oxygen concentration information. A data recording module is used to record and store oxygen concentration data. This enables the device to monitor oxygen concentration in real time, improving the ease of use of the vehicle-mounted oxygen concentration monitoring sensor device. Attached Figure Description
