Description

Technical Field

[0001] This application relates to the field of automotive air conditioning system technology, specifically to an intelligent compensation device for a temperature sensor used in automotive air conditioning. Background Technology

[0002] Temperature sensors in automotive air conditioning systems are crucial components for ensuring stable interior temperatures, and their accuracy directly impacts the system's performance and passenger comfort. With the development of intelligent vehicles, higher demands are being placed on the accuracy and response speed of temperature sensors.

[0003] In existing technologies, common temperature sensor compensation methods include hardware compensation and software compensation. Hardware compensation is usually achieved by adding compensation resistors or thermistors to the sensor circuit. This method is simple and direct, but its compensation range is limited and it is difficult to adapt to complex environmental changes. Software compensation corrects sensor data through algorithms, such as linear regression or neural network models. Although it is more flexible, it requires higher processor computing power, and the algorithm complexity may affect real-time performance.

[0004] Currently, temperature sensors are prone to drift or errors in extreme temperature environments or after prolonged use, causing the air conditioning system to be unable to accurately adjust the temperature, affecting the user experience. At the same time, the filter at the air outlet of the air conditioner becomes clogged after long-term use, which increases the airflow resistance, resulting in a reduction in the air volume and airflow speed at the outlet. In this case, the temperature sensor detects the temperature of the stagnant air, rather than the actual ambient temperature. Especially when the air conditioner is started or stopped or the temperature changes rapidly, the detected value may lag behind the actual temperature. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an intelligent compensation device for a temperature sensor used in automotive air conditioning, which has the advantages of solving the problem of inaccurate temperature detection, significantly improving the accuracy of temperature regulation in the air conditioning system and user experience, and solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: an intelligent compensation device for a temperature sensor used in automotive air conditioning, comprising an air conditioning duct, a filter plate disposed on the inner side of the air conditioning duct, a driving assembly disposed on the upper side of the air conditioning duct, the driving assembly including a bracket fixedly connected to the upper side of the air conditioning duct, a lead screw rotatably connected to the inner side of the bracket, a moving block threadedly connected to the outer side of the lead screw, a connecting rod rotatably connected to the outer side of the moving block, and a cleaning assembly disposed on the outer side of the air conditioning duct, the cleaning assembly including a moving plate, and a connecting rod fixedly connected to the outer side of the moving plate. A fixed shaft is provided, and the other end of the movable block is rotatably connected to the outside of the fixed shaft. Two symmetrical mounting plates are provided on the outside of the movable plate, and cleaning brushes are fixedly connected to the outside of both mounting plates. A controller is fixedly installed on the upper side of the air conditioner outlet duct. The controller integrates a storage module, which stores a compensation algorithm. Two temperature sensor bodies are provided inside the air conditioner outlet duct. A compensation resistor is fixedly connected to the inside of the air conditioner outlet duct. The compensation resistor is electrically connected to the temperature sensor bodies. An operational amplifier is integrated inside the compensation resistor.

[0007] The above solution, through the coordinated operation of a filter plate, drive assembly, cleaning assembly, temperature sensor body, compensation resistor, and controller, can effectively clean the filter plate by combining the action of the drive assembly and cleaning assembly, preventing filter blockage from affecting airflow and temperature detection accuracy. Furthermore, the compensation resistor and controller with stored compensation algorithms can intelligently compensate for drift and errors in the temperature sensor body caused by extreme environments or prolonged use, effectively solving the problem of inaccurate temperature detection and significantly improving the accuracy of temperature regulation in the air conditioning system and the user experience.

[0008] Furthermore, the filter plate and the air conditioner outlet pipe are fixedly connected by bolts.

[0009] With the above solution, the filter plate and the air conditioner outlet duct are fixed with bolts, which facilitates the disassembly and installation of the filter plate, and allows users to clean or replace the filter plate regularly, ensuring that the filter plate maintains a good filtration effect for a long time.

[0010] Furthermore, a servo motor is fixedly embedded on the outer side of the bracket, and the output end of the servo motor is fixedly connected to the outer side of the lead screw. The servo motor and the controller are electrically connected. A guide groove is provided on the upper side of the bracket, and the outer side of the moving block is slidably connected to the inner side of the guide groove.

[0011] With the above solution, the movement of the moving block is more stable and accurate by setting a guide groove to guide the moving block.

[0012] Furthermore, a wind force sensor is fixedly installed on the inner side of the air conditioner's air outlet duct, and the wind force sensor is electrically connected to the controller.

[0013] The above solution allows for real-time monitoring of the airflow in the air conditioning duct by installing a wind sensor, which then feeds the data back to the controller. The controller can then determine whether the filter is clogged based on the wind data. When an abnormal drop in wind force is detected, the drive and cleaning components are activated in a timely manner to clean the filter, thus achieving intelligent monitoring and automatic cleaning of filter blockage and ensuring the stability of the air conditioning output and the accuracy of temperature detection.

[0014] Furthermore, two guide rails are fixedly connected to the outer side of the air conditioner duct, and the outer side of the movable plate is slidably connected to the inner side of the guide rails.

[0015] Through the above solution, the guide rail provides stable guidance and support for the movement of the moving plate, enabling the moving plate to move smoothly along a fixed trajectory while driving the cleaning brush to clean the filter screen. This effectively prevents the moving plate from shaking or deviating, ensuring full contact between the cleaning brush and the filter screen, and improving the cleaning effect.

[0016] Furthermore, the movable plate is made of steel, and two magnets are fixedly embedded on the inner side of each of the two mounting plates, and the magnets are magnetically connected to the movable plate.

[0017] The above solution utilizes steel to ensure the strength and durability of the movable plate, enabling it to withstand the forces exerted during the cleaning process. The mounting plate and the movable plate are magnetically connected, making the installation and removal of the mounting plate more convenient. This allows users to easily replace worn cleaning brushes or damaged mounting plates, reducing maintenance costs.

[0018] Furthermore, two symmetrical positioning holes are provided on the outer sides of the two mounting plates, and two sets of symmetrical guide rods are fixedly connected to the outer side of the movable plate, with the outer side of the guide rods inserted into the inner side of the positioning holes.

[0019] The above solution, by setting guide rods and positioning holes to cooperate, plays a role in precise positioning during the installation of the mounting plate, ensuring the accurate installation position of the mounting plate and improving cleaning efficiency and quality.

[0020] Furthermore, the two temperature sensor bodies are arranged symmetrically, and the outer sides of the two temperature sensor bodies are fixedly connected to the inner side of the air conditioner outlet duct.

[0021] Through the above scheme, the two symmetrically arranged temperature sensor bodies can detect the air temperature inside the air conditioning duct from different positions, obtain more comprehensive and accurate temperature data, effectively reduce detection errors caused by local temperature differences or uneven airflow, further improve the reliability of temperature detection, and provide a more accurate basis for temperature compensation.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This intelligent compensation device for a temperature sensor used in automotive air conditioning systems employs a filter plate, a drive assembly, a cleaning assembly, a temperature sensor body, a compensation resistor, and a controller. These components work together to clean the filter plate, preventing clogging and ensuring accurate temperature detection. The compensation resistor and controller, equipped with a compensation algorithm, intelligently compensate for drift and errors in the temperature sensor body caused by extreme environments or prolonged use. This effectively solves the problem of inaccurate temperature detection, significantly improving the precision of air conditioning system temperature control and user experience. Furthermore, the two temperature sensors can detect the air temperature inside the air duct from different locations, effectively reducing detection errors caused by localized temperature differences or uneven airflow, further improving the reliability of temperature detection and providing more accurate data for temperature compensation.

[0033] Please see Figure 1 and Figure 2The filter plate 2 and the air conditioning outlet duct 1 are fixedly connected by bolts. The above-mentioned bolt fixing method for the filter plate 2 and the air conditioning outlet duct 1 facilitates the disassembly and installation of the filter plate 2, and allows users to clean or replace the filter plate 2 regularly, ensuring that the filter plate 2 maintains a good filtration effect for a long time.

[0035] Please see Figure 1 , Figure 4 and Figure 5The cleaning component 4 includes a movable plate 401, with a fixed shaft 402 fixedly connected to the outer side of the movable plate 401. The other end of the movable block 304 is rotatably connected to the outer side of the fixed shaft 402.

Two guide rails 9 are fixedly connected to the outer side of the air conditioning duct 1, and the outer side of the movable plate 401 is slidably connected to the inner side of the guide rails 9. The guide rails 9 provide stable guidance and support for the movement of the movable plate 401, so that the movable plate 401 can move smoothly along a fixed trajectory when driving the cleaning brushes 404 to clean the filter plate 2, effectively preventing the movable plate 401 from shaking or deviating, ensuring that the cleaning brushes 404 are in full contact with the filter plate 2, and improving the cleaning effect.

The mounting plate 403 is magnetically connected to the movable plate 401 via the magnets 407, making the installation and removal of the mounting plate 403 more convenient. This allows users to easily replace worn cleaning brushes 404 or damaged mounting plates 403, reducing maintenance costs. The outer sides of the two mounting plates 403 have two symmetrical positioning holes 406. The outer sides of the movable plate 401 are fixedly connected to two sets of symmetrical guide rods 405, and the outer sides of the guide rods 405 are inserted into the inner sides of the positioning holes 406.

[0036] This embodiment presents an intelligent compensation device for a temperature sensor used in automotive air conditioning. Through the coordinated operation of a filter plate 2, a drive assembly 3, a cleaning assembly 4, a temperature sensor body 7, a compensation resistor 6, and a controller 5, the device effectively cleans the filter plate 2 via the combined action of the drive assembly 3 and the cleaning assembly 4, preventing filter blockage from affecting airflow and temperature detection accuracy. Simultaneously, the compensation resistor 6 and the controller 5, which stores a compensation algorithm, intelligently compensate for drift and errors in the temperature sensor body 7 caused by extreme environments or prolonged use. This effectively solves the problem of inaccurate temperature detection, significantly improving the accuracy of air conditioning system temperature regulation and user experience. Furthermore, the two temperature sensor bodies 7 can detect the air temperature inside the air conditioning duct 1 from different locations, effectively reducing detection errors caused by local temperature differences or uneven airflow, further improving the reliability of temperature detection and providing a more accurate basis for temperature compensation.

[0037] The working principle of the above embodiment is as follows: During the operation of the air conditioner, the wind force sensor 8 monitors the wind force in the air outlet duct 1 in real time and transmits the data to the controller 5. When the wind force sensor 8 detects that the wind force is lower than the set threshold, it indicates that the filter plate 2 may be blocked. The controller 5 controls the servo motor 303 to start. The servo motor 303 drives the lead screw 302 to rotate. Under the guidance of the guide groove 306, the moving block 304 moves along the lead screw 302. Through the connecting rod 305, the moving plate 401 slides on the guide rail 9, so that the cleaning brush 404 cleans the filter plate 2 and restores air circulation. At the same time, the two temperature sensor bodies 7 symmetrically detect the temperature in the air outlet duct 1 and transmit the data to the controller 5. The controller 5, based on the compensation algorithm in the storage module and combined with the data of the temperature sensor bodies 7, performs intelligent compensation on the detection data of the temperature sensor bodies 7 through the operational amplifier in the compensation resistor 6. This corrects the problem of inaccurate temperature detection caused by sensor drift, error or environmental factors, so that the air conditioning system can accurately adjust the temperature according to the accurate temperature data and provide users with a more comfortable experience.
