Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically to an intelligent air conditioning detection system and an air conditioner. Background Technology

[0002] With the significant improvement in living standards, drivers have increasingly higher requirements for their working environment. In recent years, the demand for parking air conditioning among drivers has been growing. To improve the working environment for those working in the vehicle transportation industry, many companies have developed air conditioning systems that can be turned on while the vehicle is parked. However, turning on the air conditioning generates a large amount of heat, causing the internal components to heat up. Prolonged exposure to high temperatures can damage these components, leading to air conditioning malfunctions. Utility Model Content

[0003] The purpose of this application is to provide an intelligent air conditioning detection system and an air conditioner, which aims to solve the problem of high failure rate caused by excessive temperature rise of components in related technologies.

[0009] The electrical box is equipped with a radiator;

[0010] The baffle is disposed on an opening in the outer casing of the evaporator;

[0011] With the baffle open, more cold air is released from the opening in the outer casing of the evaporator, and the radiator comes into contact with more cold air, thus accelerating the cooling of the radiator.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in a product or system that includes the aforementioned element.

[0027] Figure 1 This application illustrates an intelligent air conditioning detection system according to an embodiment of the present application. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0028] An intelligent air conditioning detection system 1 includes an air conditioning controller 10, a component temperature detection device 11 and a baffle driving device 12 respectively connected to the air conditioning controller 10.

[0029] The aforementioned component temperature detection device 11 is installed in the electrical box and is used to detect the temperature of the components in the electrical box and send the temperature of the components to the aforementioned air conditioner controller 10. The aforementioned air conditioner controller 10 is also used to receive the detected temperature value.

[0030] The air conditioning controller 10 is used to control the operation of the baffle drive device 12. The baffle drive device 12 is used to operate under the control of the air conditioning controller 10 and drive the baffle to move.

[0031] The aforementioned electrical box is equipped with a radiator 22; the aforementioned baffle is provided on the opening in the outer casing of the evaporator 23. When the aforementioned baffle is open, more cold air is emitted from the opening in the outer casing of the aforementioned evaporator 23, and the aforementioned radiator 22 comes into contact with more cold air, thereby accelerating the cooling of the aforementioned radiator 22.

[0032] The technical solution described above, by installing a baffle in the evaporator, allows more cold air to come into contact with the radiator when the air conditioning controller opens the baffle, thus accelerating the radiator's cooling. This helps reduce the temperature rise of components in the electrical box, thereby reducing component failures caused by excessive temperature rise.

[0033] In some embodiments, the radiator 22 extends into the evaporator 23 to cool the radiator 22 using the cold air inside the evaporator 23.

[0034] In this embodiment, the radiator 22 can extend into the evaporator 23, so that the cold air in the evaporator 23 can be used to cool the radiator 22.

[0035] See appendix Figure 2 In the middle, a baffle 24 is provided at the opening of the evaporator 23. When the baffle 24 is opened in a controlled manner, more cold air will flow towards the radiator 22. If the radiator 22 is positioned close to the opening of the evaporator 23 and extends directly into the interior of the evaporator 23, it can come into contact with more cold air flowing out from the opening, which is beneficial for the radiator to cool down.

[0036] In some embodiments, see Appendix Figure 3 The front view and attached view of the baffle shown Figure 4 The diagram shows a side view of the baffle. The baffle includes a baffle body 241, with a first fixed connecting shaft 242 and a second fixed connecting shaft 243 at its two ends.

[0037] See appendix Figure 5 The first opening is provided in the first side face 231 of the evaporator 23, and the first fixed connecting shaft 242 of the baffle extends into the first opening to achieve fixation.

[0038] In this embodiment, a first bearing can be provided, and the outer sleeve of the first bearing is fixed in the first opening. The outer sleeve of the first bearing can be interference-fitted with the inner side of the first opening to achieve a more stable fixation. The first fixed connecting shaft 242 of the baffle is fitted into the inner sleeve of the first bearing, and can be interference-fitted to fasten the first fixed connecting shaft 242 of the baffle.

[0039] By setting the aforementioned first bearing, the first fixed connecting shaft 242 of the baffle can rotate freely with the inner sleeve of the first bearing. If the aforementioned first bearing is not set, the first fixed connecting shaft 242 of the baffle will directly contact the first opening in the first side face 231 of the evaporator 23. The rotation of the first fixed connecting shaft 242 will cause wear on the first opening. Long-term rotation will wear down the first opening, change its shape, and cause the baffle to shift position.

[0040] A second opening is provided in the second side facade 232 of the evaporator 23; the second fixed connecting shaft 243 of the baffle extends into the second opening to achieve fixation, and the second fixed connecting shaft 243 of the baffle is connected to the driving end of the baffle driving device.

[0041] In this embodiment, a second bearing can be provided, and the outer sleeve of the second bearing is fixed in the second opening. The outer sleeve of the second bearing can be interference-fitted with the inner side of the second opening to achieve a more stable fixation. The second fixed connecting shaft 243 of the baffle is fitted into the inner sleeve of the second bearing, and can be interference-fitted to fasten the second fixed connecting shaft 243 of the baffle.

[0042] By providing the second bearing, the second fixed connecting shaft 243 of the baffle can rotate freely with the inner sleeve of the second bearing. Without the second bearing, the second fixed connecting shaft 243 of the baffle would directly contact the second opening in the second side face 232 of the evaporator 23, and rotation of the second fixed connecting shaft 243 would cause wear on the second opening. Prolonged rotation would wear down the second opening, altering its shape and causing the baffle to shift position.

[0043] When the drive end of the aforementioned baffle drive device rotates, it drives the aforementioned baffle to rotate, thereby achieving opening and closing.

[0044] In this embodiment, the drive end of the baffle drive device is connected to the second fixed connecting shaft 243 of the baffle. Rotating the drive end will drive the second fixed connecting shaft 243 of the baffle to rotate, thereby driving the entire baffle 24 to rotate. For example, when the baffle 24 rotates 90 degrees clockwise, the baffle 24 is parallel to the bottom surface of the evaporator 23, achieving an open state. In this case, more cold air will flow out of the opening of the evaporator 23 and flow outside the evaporator 23.

[0045] When the baffle 24 is rotated 90 degrees counterclockwise, the baffle 24 is perpendicular to the bottom surface of the evaporator 23, achieving a closed state. In this case, most of the cold air is blocked by the baffle 24 inside the baffle 24 and cannot flow through the opening of the evaporator 23.

[0046] In some embodiments, the baffle driving device 12 is a stepper motor.

[0047] In this embodiment, the stepper motor can move in both forward and reverse directions. The output shaft of the stepper motor can be connected to the second fixed connecting shaft 243 of the baffle. When the stepper motor rotates 90 degrees in the first direction, it can drive the baffle to open. When the stepper motor rotates 90 degrees in the second direction, it can drive the baffle to close.

[0048] In some embodiments, see Appendix Figure 5 It also includes a circular buckle 3, which is fitted onto the first fixed connecting shaft 242 of the baffle. The first side of the circular buckle 3 is attached to the inner side of the first side facade 231 of the evaporator 23 to fix the first fixed connecting shaft 242 and prevent the baffle 24 from moving axially.

[0049] In some embodiments, see Appendix Figure 6 The intelligent air conditioning detection system 1 also includes a battery voltage detection unit 4 connected to the air conditioning controller 10. The battery voltage detection unit 4 is used to detect the voltage of the battery and send the detected battery voltage to the air conditioning controller 10.

[0050] In some embodiments, the intelligent air conditioning detection system 1 further includes a communication circuit 5, which is used to enable the air conditioning controller 10 to communicate with the motherboard.

[0051] The communication circuit 5 may employ various technologies and protocols to transmit data, including but not limited to serial communication, parallel communication, and network communication. For communication between the air conditioner controller 10 and the main board, the communication circuit needs to ensure the accuracy and timeliness of data transmission so that the air conditioner controller can accurately obtain the main board's status information and adjust the air conditioner's operating parameters as needed. Simultaneously, the communication circuit also needs to possess a certain level of anti-interference capability to ensure stable operation in complex electromagnetic environments.

[0052] In some embodiments, the intelligent air conditioning detection system 1 further includes a 4G module communication unit 6, which is used to enable communication between the cloud server and the air conditioning controller 10.

[0053] In this embodiment, the 4G module communication unit 6 can send the temperature value detected by the thermistor to the cloud server. After receiving the temperature value, the cloud server can store it. The 4G module communication unit 6 can also report the commands sent by the air conditioner controller 10 to the baffle drive device 12 to the cloud controller. The cloud controller records and stores the commands sent by the air conditioner controller 10 to the baffle drive device 12.

[0054] In some embodiments, the component temperature detection device 11 is a thermistor, which is disposed on a circuit board in the electrical box and is used to detect the temperature rise of the components in the electrical box.

[0055] In this embodiment, the resistance value of the thermistor is affected by temperature and changes with temperature. The corresponding temperature change can be calculated by measuring the change in the thermistor's resistance value. When the components in the electrical box experience a temperature rise, the resistance value of the thermistor will also increase. By detecting the increase in resistance value, the increased temperature can be determined.

[0056] In some embodiments, the air conditioning controller 10 may further include a main controller and a drive controller. The main controller mainly performs temperature sensor detection, stepper motor operation control, battery voltage and current detection, 4G module control, and 485 communication with the drive board. In addition to communicating with the main controller, the drive controller also drives the fan and compressor load.

[0057] See appendix Figure 2 This application proposes an air conditioner, including the aforementioned intelligent air conditioner detection system 1, and an electrical box 21, on which a radiator 22 is provided. The radiator 22 is used to dissipate heat from the electrical box 21. The radiator 22 is disposed close to the evaporator 23. The outer casing of the evaporator 23 is provided with the aforementioned baffle 24.

[0058] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
