Description

Technical Field

[0001] This invention relates to the field of intelligent control technology, specifically providing a control method and vehicle for a vehicle-mounted roof-mounted air conditioner. Background Technology

[0002] Existing commercial vehicle rooftop air conditioning systems generally rely on power batteries for power. Under high-speed conditions, air conditioning power consumption accounts for as much as 20%-35% of the vehicle's total energy consumption, becoming a key factor restricting the vehicle's range. Taking electric heavy trucks as an example, at a speed of 100km / h, the air conditioning system can consume 3-5kWh per hour, directly resulting in a 15%-25% reduction in range. At the same time, the wind resistance kinetic energy borne by the roof during vehicle operation is completely wasted, and the roof space remains idle for a long time.

[0003] Existing technologies attempt to recover wind resistance kinetic energy by adding wind power generation devices, but they generally suffer from three major drawbacks: First, the energy conversion efficiency is less than 30%, far below the theoretical value; second, the power generation fluctuation exceeds ±40%, leading to unstable operation of the air conditioning system; and third, there is a lack of intelligent control strategies that adapt and coordinate with the vehicle's operating conditions, making it impossible to dynamically adjust the power generation and supply modes based on parameters such as vehicle speed, load, and ambient temperature. These technical bottlenecks make it difficult for existing wind power generation devices to provide stable power in actual operation, and may even trigger overload protection of the battery management system due to power fluctuations.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

Detailed Implementation

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are described in conjunction with a vehicle roof-mounted air conditioner, the control method for a vehicle roof-mounted air conditioner provided by the present invention is equally applicable to other products that need to solve the problem of low energy conversion efficiency in roof-mounted wind power generation devices.

[0021] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Based on the background art's description of the low energy conversion efficiency of existing roof-mounted wind power generation devices in commercial vehicles, this invention provides a control method for a vehicle-mounted roof-mounted air conditioner. This method aims to adjust the angle of the air deflector according to vehicle speed to ensure the wind turbine operates at its optimal condition, thereby effectively solving the problem of low energy conversion efficiency in existing roof-mounted wind power generation devices for commercial vehicles.

[0023] The present invention provides a vehicle-mounted roof air conditioner, which includes a housing and a wind power generation device and an air conditioning unit installed in the housing. The front end of the housing is provided with an angle-adjustable deflector. The vehicle is equipped with an energy storage mechanism connected to the wind power generation device, and the electrical energy generated by the wind power generation device can be stored in the energy storage mechanism.

[0024] The vehicle-mounted roof-mounted air conditioning system provided by this invention mainly consists of a housing, a wind power generation device, an air conditioning unit, an adjustable-angle air deflector, and an energy storage mechanism connected to the wind power generation device. The housing serves as the external protective structure for the entire air conditioning system, housing the wind power generation device and the air conditioning unit. The wind power generation device is a component that generates electricity using wind power produced during vehicle operation. The generated electrical energy can be stored in the energy storage mechanism and used to power other devices when needed. The adjustable-angle air deflector is located at the front end of the housing; its function is to guide and regulate the direction and speed of airflow entering the housing. By adjusting the angle of the air deflector, the wind power generation device can be optimized for power generation efficiency.

[0025] Preferably, the wind power generation device is a multi-rotor wind turbine, with a drive motor installed inside the casing. The drive motor can drive the guide vane to rotate for angle adjustment.

[0026] Compared to single-rotor generators, multi-rotor wind turbines have more rotors participating in energy conversion simultaneously. Under the same wind conditions, multiple rotors can capture more wind energy, increasing power generation. For example, when a vehicle is moving or parked, deflectors guide airflow evenly onto multiple rotors, each of which can independently convert wind energy into mechanical energy, which is then converted into electrical energy by the generator. The combined power generation of multiple rotors significantly improves overall power generation efficiency.

[0027] The drive motor can precisely drive the deflector to rotate, enabling flexible adjustment of the deflector angle. Under different vehicle driving conditions (such as high speed, low speed, and parking) and weather conditions, the deflector can be adjusted to the optimal angle according to the actual situation, precisely guiding the airflow to the multi-rotor wind turbine, so that the airflow can drive the rotor to rotate in the most efficient way, thereby improving power generation efficiency.

[0028] In addition, such as Figure 1 As shown, the present invention also provides a control method for a vehicle rooftop air conditioner, the control method comprising: S100: Obtain the vehicle's speed; S200: Adjusts the angle of the deflector according to vehicle speed; S300: Obtains the power output of the wind power generation device; S400: Based on the power generation capacity and the power consumption of the air conditioning unit, the air conditioning unit is selectively powered through a wind power generation device and / or an energy storage mechanism.

[0029] For example, the vehicle speed sensor and other devices equipped on the vehicle in this invention can acquire the vehicle's current driving speed in real time. Vehicle speed is a key parameter because different vehicle speeds result in different wind speeds and wind directions, which in turn affect the power generation efficiency of the wind turbine and the need for adjusting the angle of the deflector.

[0030] Then, based on the acquired vehicle speed, the system adjusts the angle of the deflector according to a preset algorithm or logic. For example, when the vehicle speed is high, the deflector may need to be adjusted to a specific angle to allow airflow to enter the casing more smoothly and impact the wind power generation device, thereby improving power generation efficiency; when the vehicle speed is low, the deflector angle is adjusted to optimize airflow conditions, ensuring that the wind power generation device can still maintain a certain power generation capacity.

[0031] Next, power sensors and other equipment are used to monitor the current power generation of the wind power generation unit in real time. The power generation directly reflects the energy conversion efficiency of the wind power generation unit under its current operating conditions, and is one of the important bases for deciding how to supply power to the air conditioning unit.

[0032] Finally, the system compares the power output of the wind turbine with the power consumption of the air conditioning unit. If the power output is greater than or equal to the power consumption, it means that the electrical energy generated by the wind turbine is sufficient to meet the needs of the air conditioning unit, and the wind turbine can directly supply power to the air conditioning unit. If the power output is less than the power consumption, it means that the electrical energy generated by the wind turbine is insufficient to meet the needs of the air conditioning unit. In this case, the system will simultaneously draw on the electrical energy stored in the energy storage device to supply power to the air conditioning unit together with the wind turbine, ensuring that the air conditioning unit can operate normally.

[0033] Therefore, by adjusting the angle of the deflector according to the vehicle speed, this invention optimizes the airflow conditions entering the casing, ensuring the wind power generation device is always in a relatively ideal working state, thereby effectively improving the energy conversion efficiency of the wind power generation device. Compared to existing commercial vehicle rooftop wind power generation devices, it is no longer limited to fixed airflow conditions and can dynamically adjust according to actual driving conditions, making full use of wind resources during vehicle operation and converting more wind energy into electrical energy.

[0034] Furthermore, the system intelligently selects the power supply method based on the power output of the wind power generation unit and the power consumption of the air conditioning unit, achieving rational allocation and utilization of energy. When wind power generation is sufficient, it prioritizes the use of wind power, reducing reliance on energy storage mechanisms and extending their service life. When wind power generation is insufficient, it promptly draws on the power from the energy storage mechanism to supplement the system, ensuring the continuous and stable operation of the air conditioning unit and improving the reliability and stability of the entire vehicle air conditioning system.

[0035] Preferably, such as Figures 2 to 4 As shown, step S200 specifically includes: When the vehicle speed is within the first speed range, the deflector will be deployed to the first angle; When the vehicle speed is within the second speed range, the deflector will be deployed to the second angle; When the vehicle speed is within the third speed range, deploy the deflector to the third angle; Among them, the first vehicle speed range is lower than the second vehicle speed range, the second vehicle speed range is lower than the third vehicle speed range, the first angle is smaller than the second angle, and the second angle is smaller than the third angle.

[0036] When the vehicle speed is within the first speed range (which is relatively low), the deflector is deployed to the first angle. Because the airflow velocity and intensity entering the casing are relatively low at lower speeds, a smaller deflector angle helps guide the airflow in the appropriate direction and speed, enabling the wind power generation device to initially and effectively utilize wind energy for power generation. For example, in congested urban traffic conditions, vehicles frequently start and stop, and their speeds are mostly within this low range. In this case, setting the first angle allows the deflector to better adapt to this low-speed airflow environment.

[0037] For example, the first vehicle speed range of the present invention is greater than 0 km / h and less than or equal to 40 km / h, and the first angle is 20° to 30°. Of course, in other embodiments, the first vehicle speed range and the first angle range can be set to other values, and the present invention does not specifically limit the first vehicle speed range and the first angle range.

[0038] When the vehicle speed is within the second speed range (medium speed), the deflector is deployed to the second angle. As the vehicle speed increases, the airflow velocity and intensity increase, requiring an appropriate increase in the deflector angle to more effectively guide the airflow to impact the wind turbine and improve power generation efficiency. For example, when driving normally on urban expressways or ordinary roads, the vehicle speed may fall within this range, and the second angle allows the deflector to better match the medium-speed airflow conditions.

[0039] For example, the second vehicle speed range of the present invention is greater than 40 km / h and less than or equal to 80 km / h, and the second angle is 30° to 50°. Of course, in other embodiments, the second vehicle speed range and the second angle range can also be set to other values, and the present invention does not specifically limit the second vehicle speed range and the second angle range.

[0040] When the vehicle speed is within the third speed range (higher speed), the deflector is deployed to the third angle. At high speeds, the airflow is very strong; a larger deflector angle prevents excessive airflow impact on the casing, thus avoiding energy loss. It also allows more airflow to effectively act on the wind turbine, further increasing power generation. For extended periods of high-speed driving on highways, where speeds are high, the third angle setting allows the deflector to function optimally.

[0041] For example, the third vehicle speed range of the present invention is greater than 80 km / h, and the third angle is 50° to 70°. Of course, in other embodiments, the third vehicle speed range and the third angle range can be set to other values, and the present invention does not specifically limit the third vehicle speed range and the third angle range.

[0042] This invention divides vehicle speed into different ranges and sets different guide vane angles accordingly, enabling the guide vanes to precisely adjust the way airflow enters the housing based on the actual vehicle speed. Within each speed range, the guide vane angle can guide the airflow to impact the wind power generation device in the best possible way, avoiding energy waste caused by inappropriate angles, thereby significantly improving the energy conversion efficiency of the wind power generation device at different vehicle speeds.

[0043] By improving the power generation efficiency of wind turbines at different vehicle speeds, the system can acquire more electrical energy. Combined with subsequent intelligent power supply management based on power generation and air conditioning unit power consumption, energy can be allocated and utilized more rationally. While ensuring normal power supply to the air conditioning unit, maximizing wind power generation and reducing reliance on energy storage mechanisms further improves the overall system's energy efficiency and sustainability.

[0044] Preferably, such as Figure 2 As shown, in the first embodiment, step S400 specifically includes: When the power generation capacity equals the power consumption of the air conditioning unit, the wind power generation device supplies power to the air conditioning unit.

[0045] When the power generation capacity equals the power consumption of the air conditioning unit, the electrical energy generated by the wind power generation device is just enough to meet the power requirements for the normal operation of the air conditioning unit. Therefore, the air conditioning unit can be directly powered by the wind power generation device, without the need to obtain electrical energy from other energy storage devices, and there will be no excess electrical energy to store. This state represents an ideal supply and demand balance, achieving direct and efficient utilization of energy.

[0046] Preferably, such as Figure 3 As shown, in the second embodiment, step S400 specifically includes: When the power generation capacity exceeds the power consumption of the air conditioning unit, the wind power generation device supplies power to the air conditioning unit and stores the excess electrical energy in the energy storage mechanism; When the power generation capacity exceeds the power consumption of the air conditioning unit, the wind power generation device, with its strong power generation capability, generates more electricity than the air conditioning unit currently requires. In this case, the wind power generation device first supplies power to the air conditioning unit. Simultaneously, to avoid wasting excess energy, the excess energy is stored in an energy storage system. This energy storage system can then release the stored energy to power the air conditioning unit during subsequent vehicle operation when wind power generation is insufficient. This achieves rational allocation and full utilization of energy, significantly improving the overall energy efficiency of the system.

[0047] Preferably, such as Figure 4 As shown, in the third embodiment, step S400 specifically includes: When the power output of the wind power generation device is less than the power consumption of the air conditioning unit, the wind power generation device and the energy storage device jointly supply power to the air conditioning unit.

[0048] When the power output of the wind turbine is less than the power consumption of the air conditioning unit, the generated electricity cannot meet the unit's power requirements. To ensure the air conditioning unit can continue to operate normally, both the wind turbine and the energy storage system need to supply power. The wind turbine continues to generate electricity, while the energy storage system releases previously stored energy. Together, they supplement the insufficient power, improving the reliability and stability of the vehicle's rooftop air conditioning system and providing a consistently comfortable environment inside the vehicle.

[0049] Preferably, the energy storage mechanism includes a capacitor and a lithium battery installed inside the vehicle, and the electrical energy generated by the wind power generation device can be stored in the capacitor and / or lithium battery. The step of "the wind power generation device and the energy storage mechanism jointly powering the air conditioning unit" specifically includes: The air conditioning unit is initially powered by a combination of wind power generation equipment and capacitors. When the charge in the capacitor is lower than the preset charge, the air conditioning unit will be powered by the wind power generation device and the lithium battery.

[0050] When the power output of the wind turbine is less than the power consumption of the air conditioning unit, the stored electrical energy in the capacitor is used first, along with the wind turbine, to power the air conditioning unit. Because the capacitor can release electrical energy quickly, it can promptly supplement the insufficient power supply from the wind turbine, ensuring that the air conditioning unit receives stable power support in a short period of time, and preventing the air conditioning unit from degrading in performance or stopping operation due to insufficient power supply.

[0051] As the capacitor continuously releases electrical energy, when its charge drops to a preset level (e.g., below 10%–20% of the capacitor's rated capacity), it indicates that the energy in the capacitor is insufficient to effectively support the operation of the air conditioning unit. At this point, the system automatically switches to a mode where the air conditioning unit is powered jointly by the wind turbine and the lithium battery. The lithium battery stores more energy, providing longer-lasting power support and ensuring the air conditioning unit can operate stably for an extended period, until the wind turbine's power output can once again meet the air conditioning unit's power needs or the vehicle's operating conditions change.

[0052] This invention prioritizes the use of electricity stored in a capacitor when the air conditioning unit is powered by both a wind power generator and an energy storage system. Only when the capacitor's charge is insufficient is the lithium battery's charge used. This avoids the problem of frequent use of the lithium battery to power the air conditioning unit, which would accelerate lithium battery depletion and shorten the vehicle's driving range. The capacitor, as an auxiliary energy storage element, reduces the burden on the lithium battery by prioritizing its charge usage, thus minimizing battery power loss and maintaining stable vehicle range, giving consumers a more reliable expectation of the vehicle's driving capability.

[0053] Preferably, the control method further includes: When the vehicle is detected to be in a parked state, the deflector is deployed to the parking opening, which is 70° to 90°. Obtain the wind direction in the environment; Adjust the deflector to face the direction of the airflow.

[0054] For example, the present invention equips the vehicle with corresponding sensors to acquire wind direction information in the environment. These sensors can be wind direction sensors, which can sense the direction of airflow in the surrounding environment in real time and transmit this data to the vehicle's control unit. By accurately acquiring the wind direction, the system can further adjust the angle of the deflector according to the actual situation to achieve the best wind guidance effect.

[0055] After acquiring the wind direction in the environment, the control unit precisely adjusts the angle of the deflector to face the wind. This allows natural wind to pass through the deflector without obstruction, enabling the vehicle to generate electricity even when stationary. This significantly expands the application scenarios of wind power, no longer limiting it to when the vehicle is in motion, increasing energy acquisition opportunities, and making it possible to continuously replenish the vehicle's power while parked.

[0056] Preferably, the control method further includes: Check the weather conditions at the vehicle's location; When severe weather conditions are detected, adjust the angle of the deflector to a safe position; Severe weather conditions include strong winds, rain, or snow.

[0057] For example, the vehicle of the present invention is equipped with weather sensors that can measure parameters such as temperature, humidity, wind speed, and wind direction of the surrounding environment in real time, and make a preliminary judgment on the weather conditions by analyzing these parameters. For example, when the wind speed sensor detects that the wind speed continuously exceeds a certain threshold, it may indicate the arrival of strong winds.

[0058] In severe weather conditions, such as strong winds, rain, or snow, air deflectors are susceptible to damage. Strong winds can exert excessive force on the deflector, causing it to deform, break, or loosen its connections. Rain and snow can accumulate on the deflector's surface, increasing its weight, and melting snow can seep into the deflector, leading to corrosion and electrical malfunctions. Adjusting the air deflector to a safe position can effectively reduce the damage caused by these adverse factors, extend its lifespan, and lower vehicle maintenance costs.

[0059] Furthermore, the vehicle provided by the present invention also includes a controller configured to execute the above-described control method.

[0060] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
