Technical Field
[0001] The utility model relates to the technical field of automobile air-conditioning controllers, in particular to an automobile air-conditioning controller with a dustproof structure. Background Art
[0002] The car air conditioning controller is the core component of the modern car's internal environmental control system. It is responsible for adjusting the temperature, humidity and air circulation in the car to provide a comfortable and healthy riding environment for the driver and passengers. With the development of the automobile industry and consumers' pursuit of automobile comfort, the importance of the car air conditioning controller has become increasingly prominent. The car air conditioning controller adjusts the fan speed, temperature setting, etc. through knobs or switches.
[0003] For example, the Chinese authorized patent "A Automobile Air Conditioning Controller" with announcement number CN202371842U includes a single-chip microcomputer, a driver chip, a connector, a temperature adjustment knob, an air volume adjustment knob and a mode adjustment knob on the panel, and is characterized in that the circuit boards at the bottom of the temperature adjustment knob, the air volume adjustment knob and the mode adjustment knob are connected to the entire circuit board through multiple connecting ribs, and the entire circuit board is arranged on the bottom cover. The function of the air conditioning controller for left-hand drive vehicles is maintained, and the appearance remains unchanged. Only the connecting rib structure is set inside the three knobs to ensure that the knobs collapse and fall off when subjected to excessive external force, meeting the requirements of the relevant regulations on protrusion height.
[0004] Although the above-mentioned prior art can realize the control of the automobile air conditioning system, with long-term use, dust is easy to adhere to the surface of the air conditioning modulator. The dust may contain corrosive substances. If it adheres to the surface of the controller or the internal circuit board for a long time, it may corrode the metal parts or electronic components of the controller. The dust may also affect the signal transmission and accuracy of the air conditioning controller. If dust adheres to the sensor or interface of the controller, it may interfere with its normal signal transmission, resulting in a decrease in the control accuracy of the air conditioning system. Therefore, it does not meet the existing needs. In this regard, we propose an automobile air conditioning controller with a dustproof structure. Utility Model Content

[0014] Preferably, limiting sliding grooves are provided on the outer walls on both sides of the dust cover.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model is provided with a dust cover that automatically opens and closes. Under normal circumstances, the dust cover covers the front end of the control panel to prevent dust from entering. A capacitive sensor is installed at the front end of the dust cover. The capacitive sensor can detect the approach of an object. When a hand approaches, the capacitance value of the sensor will change, thereby triggering the sensor. The microcontroller receives the signal of the capacitive sensor and starts the dual-axis motor according to the signal. The output shaft drives the driving gear to rotate through the driving shaft, and forms a meshing transmission with the internal tooth groove of the transmission groove. The fixed box cooperates with the sliding limit on both sides of the dust cover, so that the dust cover moves upward until it is stored in the fixed box. At this time, the control panel is exposed to the external environment, and the user can conveniently operate the air-conditioning system. When the hand leaves the detection range of the capacitive sensor, the microcontroller drives the dual-axis motor to reverse, driving the dust cover to descend, and covering the control panel again. The structure has a strong dust-proof effect, minimizes the contact between dust and the control panel, and the automatic opening and closing mechanism will not hinder daily operations.
[0017] 2. The utility model sets a dust removal mechanism at the rear end of the fixed box, and starts the negative pressure fan at a fixed time to quickly discharge the internal air. At the same time, the air outside the dust suction port is continuously replenished into the negative pressure fan, forming a higher pressure difference with the outside. Under the cover of the dust cover, the control panel is in a negative pressure environment, so that the dust remaining on the surface is sucked into the dust storage cavity through the dust suction port, ensuring the cleanliness of the surface of the control panel.
[0018] 3. The utility model installs a hair roller at the bottom of the dust cover. As the dust cover moves up and down, the hair roller will come into contact with the operating knob and the operating button to further clean the dust on the surface. In conjunction with the negative pressure fan, the dust residue on the surface of the operating knob and the operating button can be reduced to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS

By installing a capacitive sensor 16 at the front end of the dust cover 5, the capacitive sensor 16 can detect the approach of an object. When the hand approaches, the capacitance value of the capacitive sensor 16 will change, thereby triggering the sensor. The microcontroller 18 receives the signal of the capacitive sensor 16 and starts the dual-axis motor 14 according to the signal. Its output shaft drives the driving gear 13 to rotate through the driving shaft 15, and forms a meshing transmission with the internal tooth groove 12 of the transmission groove 11, and cooperates with the sliding limit of the fixed box 4 on both sides of the dust cover 5, so that the dust cover 5 moves upward until it is stored in the fixed box 4.
