Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically to an in-vehicle environment control system, control method, and automobile. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Currently, after a vehicle is turned off and parked, the interior temperature and air quality deteriorate rapidly. Existing in-vehicle solar power systems are limited in function, either only for ventilation or charging the battery, and cannot achieve continuous and stable regulation of the interior environment. For example, there is a solar-powered car sunroof power supply control method, system, and vehicle that determines whether to activate the blower fan based on the interior temperature when the car is off. If the blower fan needs to be activated, it is powered by the solar panels and / or the battery based on the sunlight intensity received by the solar panels. This control method makes more rational and effective use of solar energy, achieving energy conservation and environmental protection. However, this method only promotes air circulation and lowers the interior temperature by turning on the blower fan; it cannot purify the interior environment. When the blower fan is working, it easily brings external impurities and dust into the car, thus polluting the interior. There is also a solar-powered air purification system and vehicle that is equipped with an air purification device, which includes a blower fan, an ion generator, and a fragrance module. This system can purify the interior, but it cannot regulate the interior temperature. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an in-vehicle environment control system, control method and automobile, which can simultaneously regulate the in-vehicle temperature and air quality, and has a high degree of integration, making it convenient to install in the vehicle.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention provide an in-vehicle environmental control system, including an environmental control mechanism for installation on a roof trim panel. The environmental control mechanism includes a housing, and within the housing, along the direction from the exterior to the interior of the vehicle, a filter, an adsorption layer, a fragrance module, a fan, a temperature control component, and a phase change material block are sequentially arranged. It also includes a solar thin-film battery and an energy storage device. The solar thin-film battery is used to install on the vehicle's sunroof glass and is connected to the fan and temperature control component through a first power supply circuit assembly. The energy storage device is connected to the fan and temperature control component through a second power supply circuit assembly. The solar thin-film battery is connected to the energy storage device through a charging circuit to charge the energy storage device.

[0006] Optionally, the energy storage device is a capacitor, which is connected to a solar thin-film battery via a charging circuit.

[0007] Optionally, the adsorption layer is an activated carbon layer.

[0008] Optionally, the temperature control component uses a thermoelectric cooler, which is connected to the control unit to receive instructions from the control unit to operate.

[0009] Optionally, the filter is a HEPA filter.

[0010] Optionally, it also includes a temperature sensor and an air quality sensor for installation inside the vehicle, which are connected to the control unit.

[0011] Secondly, embodiments of the present invention provide a control method for an in-vehicle environment control system, comprising the following steps: Real-time monitoring of the vehicle's interior temperature; When the acquired interior temperature value is within the threshold range between the upper and lower temperature limits, the current state is maintained. When the obtained in-vehicle temperature value is higher than the upper limit of temperature, the temperature control component is activated to the cooling state, the fan is turned on, the outside air is purified by the filter and adsorption layer, the fragrance is carried by the fragrance module, and then the temperature is cooled by the temperature control component before entering the in-vehicle air to cool down until the in-vehicle temperature drops to the threshold range, and at the same time the cold energy is stored in the phase change material block. When the obtained interior temperature is lower than the upper limit, the temperature control component is activated to the heating state, the fan is turned on, the outside air is purified by the filter and adsorption layer, and after the fragrance module carries the fragrance, it is heated by the temperature control component and enters the car. At the same time, the phase change material block releases heat to heat the air inside the car until the interior temperature rises to the set threshold range.

[0012] Optionally, when the power generation of the solar thin-film battery is not less than the power of the fan and temperature control component, the first power supply circuit component operates to power the fan and temperature control component using the solar thin-film battery; otherwise, the second power supply circuit component operates to power the fan and temperature control component using the energy storage device.

[0013] Thirdly, embodiments of the present invention provide a car equipped with the in-vehicle environment control system described in the first aspect.

[0014] Optionally, the solar thin-film battery is installed in the interlayer of the vehicle's sunroof glass, and the housing is detachably and fixedly connected to the roof trim panel by fasteners.

[0015] The beneficial effects of this invention are as follows: 1. The in-vehicle environment control system and control method of the present invention, wherein the environment regulation mechanism includes a housing, and a filter, an adsorption layer, an aroma module, a fan, a temperature regulation component, and a phase change material block are sequentially arranged inside the housing along the direction from the outside of the vehicle to the inside of the vehicle. When the fan and the temperature regulation component work to regulate the temperature inside the vehicle, the air entering the vehicle from the outside can be purified by the filter and the adsorption layer under the drive of the fan, and at the same time, the aroma module carries the aroma. While regulating the temperature inside the vehicle, the air can be purified inside the vehicle, thus realizing the functions of regulating the temperature inside the vehicle and purifying the environment. Moreover, the relevant equipment for the temperature regulation function and the purification function are all integrated inside the housing, which has a compact structure, occupies little space, is convenient to install, and requires little modification to the vehicle.

[0016] 2. The in-vehicle environment control system and control method of the present invention further include a solar thin-film battery and an energy storage device. The solar thin-film battery is connected to the fan and temperature control component through a first power supply circuit assembly, and the energy storage device is connected to the fan and temperature control component through a second power supply circuit assembly. When there is sufficient sunlight, such as during the day, the power generation of the solar thin-film battery meets the requirements and can be used to supply power while charging the energy storage device. When there is insufficient sunlight, such as at night, the power generation of the solar thin-film battery cannot meet the requirements, and the energy storage device can be used to supply power. The entire system can work 24 hours a day without interruption and can work without starting the vehicle. The energy storage device is charged using the solar thin-film battery, which is the only power source and does not require additional power consumption. Attached Figure Description

[0019] Example 1 This embodiment provides an in-vehicle environment control system, such as... Figure 1 As shown, it includes an environmental control mechanism, a solar thin-film battery 1, and an energy storage device. The solar thin-film battery 1 is used to be installed in the interlayer of the vehicle's sunroof glass 2. The environmental control mechanism includes a housing 13, which is used to be fixedly connected to the vehicle's roof trim panel. Along the direction from the outside to the inside of the vehicle, the housing 13 is sequentially provided with a filter, an adsorption layer, a fragrance module, a fan, a temperature control component, and a phase change material block.

[0020] In this embodiment, the air inlet is provided on the air inlet side wall of the housing, the filter is a HEPA filter 3, the HEPA filter 3 is fixedly connected to the inner side of the housing, and its cross-section covering the housing is set to filter the incoming air, the adsorption layer is an activated carbon layer 4, the activated carbon layer 4 is fixedly connected to the housing, and its cross-section covering the housing is set to adsorb dust and impurities in the incoming air.

[0021] The fragrance module 5 can be an existing car fragrance module, and its specific structure will not be described in detail here. The fragrance module 5 can add fragrance to the air flowing into the car.

[0022] The HEPA filter 3, activated carbon layer 4, and fragrance module 5 together constitute the purification module.

[0023] The fan is a centrifugal fan 6, which can draw air from outside the vehicle into the vehicle.

[0024] The temperature control component employs a semiconductor cooling chip 7, which has both a cooling mode and a heating mode. Existing equipment can be used for the semiconductor cooling chip 7, which is fixedly connected to the housing via a frame made of insulating material.

[0025] The phase change material block 8 is placed inside the receiving box. The box wall is a porous structure. The receiving box is fixedly connected to the shell. The phase change material block 8 is made of existing PCMs phase change materials that can store cold and heat. It can absorb and release heat, which will not be described in detail here.

[0026] The activated carbon in the activated carbon layer is also placed in a container. The container wall has a porous structure, and the container is fixedly connected to the shell.

[0027] The air outlet side wall of the housing is provided with multiple air outlets arranged in an array for air to flow out.

[0028] The centrifugal fan 6 and the thermoelectric cooler 7 are connected to the control unit 9. In this embodiment, the control unit 9 is an independently set control unit, which can control the operation of the centrifugal fan 6 and the thermoelectric cooler 7.

[0029] The solar thin-film battery 1 is connected to the centrifugal fan 6 and the semiconductor cooling chip 7 through the first power supply line assembly, and the solar thin-film battery 1 can supply power to the centrifugal fan 6 and the semiconductor cooling chip 7 through the first power supply line assembly.

[0030] The energy storage device uses a capacitor 10, which is connected to a solar thin-film battery 1 via a charging line. The solar thin-film battery 1 can charge the capacitor 10.

[0031] Capacitor 10 is connected to centrifugal fan 6 and semiconductor cooling chip 7 through the second power supply line assembly. When capacitor 10 discharges, it can supply power to centrifugal fan 6 and semiconductor cooling chip 7 through the second power supply line assembly.

[0032] The first power supply line assembly and the second power supply line assembly are connected to the control unit 9. The control unit 9 can control the on and off of the first power supply line assembly and the second power supply line assembly, thereby realizing the switching between solar thin film battery power supply and capacitor power supply.

[0033] The first power supply line assembly and the second power supply line assembly, as well as their connection to the control unit 9, can be achieved using existing technologies and will not be described in detail here.

[0034] The control lines between the first power supply line assembly, the second power supply line assembly, and the control unit 9 and the centrifugal fan 6 and the semiconductor cooling chip 7 are installed inside the vehicle body.

[0035] It also includes a temperature sensor 11 and an air quality sensor 12, which are installed inside the vehicle to detect the temperature and air quality inside the vehicle. Both the temperature sensor 11 and the air quality sensor 12 can be existing sensors, and their installation locations inside the vehicle can be set according to actual needs, which will not be described in detail here.

[0036] Temperature sensor 11 and air quality sensor 12 are both connected to control unit 9 and can transmit the detected information to control unit 9. Temperature sensor 11 and air quality sensor 12 are also connected to solar thin-film battery 1 through a first power supply line assembly and can be powered by solar thin-film battery 1. Temperature sensor 11 and air quality sensor 12 are also connected to capacitor 10 through a second power supply line assembly and can be powered by capacitor 10.

[0037] The installation locations of temperature sensor 11 and air quality sensor 12 inside the vehicle can be set according to actual needs, and will not be described in detail here.

[0038] Example 2 This embodiment provides a control method for the automotive in-vehicle environment control system described in Embodiment 1, such as... Figure 2 As shown, it includes the following steps: The temperature inside the vehicle, T, is acquired in real time by the temperature sensor 11 and transmitted to the control unit 9.

[0039] Control unit 9 determines whether the interior temperature is within the set threshold range formed by the upper temperature limit and the lower temperature limit. In this embodiment, the lower temperature limit is 21°C and the upper temperature limit is 25°C.

[0040] When the temperature sensor 11 measures an interior temperature that is not less than 21°C and not greater than 25°C, it is determined that the interior temperature is within the set threshold range. At this time, the current state remains unchanged, and the centrifugal fan and semiconductor cooling chip do not work.

[0041] When the temperature sensor 11 measures an interior temperature greater than the upper limit, i.e., greater than 25°C, the control unit 9 activates the semiconductor cooling chip 7 to operate in cooling mode, and simultaneously activates the centrifugal fan 6 to deliver air. Under the action of the centrifugal fan 6, the outside air flows through the filter and activated carbon layer 4 for purification, then flows through the fragrance module 5 carrying fragrance, and then flows through the semiconductor cooling chip 7 for cooling. The cooled air passes through the phase change material block 8 and is then blown into the vehicle to cool the interior until the interior temperature drops to a target temperature value within the set threshold range.

[0042] In this process, the cooled air passes through the phase change material block 8 and stores the cold energy in the phase change material block 8.

[0043] When the temperature sensor 11 measures an interior temperature lower than the lower limit, i.e., less than 21°C, the control unit 9 activates the semiconductor cooling chip to operate in heating mode. The phase change material block releases heat into the interior, and the centrifugal fan 6 is activated. Under the action of the centrifugal fan 6, the air outside the vehicle flows through the filter and activated carbon layer 4 for purification, then flows through the fragrance module 5 to carry the air, and then flows through the semiconductor cooling chip 7 to be heated. The heated air passes through the phase change material block 8 and is then blown into the interior to heat the interior until the interior temperature rises to a target temperature value within the set threshold range.

[0044] In this embodiment, the target temperature value can be set according to actual needs, and will not be described in detail here.

[0045] In this embodiment, the control system and method, when the centrifugal fan 6 and the semiconductor cooling chip 7 are working to regulate the temperature inside the vehicle, allow the air entering the vehicle from the outside to be purified by the filter and activated carbon layer 4 under the drive of the centrifugal fan 6. At the same time, the fragrance module 5 carries fragrance. While regulating the temperature inside the vehicle, it does not bring dust and impurities from the external environment into the vehicle, thus purifying the interior environment. It achieves both temperature regulation and environmental purification functions. Moreover, the related equipment for temperature regulation and purification functions are all integrated inside the housing, resulting in a compact structure, small space occupation, convenient installation, and minimal modification to the vehicle.

[0046] Furthermore, such as Figure 3 As shown, in this embodiment, the air quality inside the vehicle is also detected in real time by the air quality sensor 12. When the PM2.5 level inside the vehicle is greater than 75 μg / m³, the sensor will detect the PM2.5 level. 3 When the air is in use, the control unit 9 controls the centrifugal fan 6 to work. The air outside the vehicle flows through the filter, activated carbon layer 4, fragrance module 5, and phase change material block 8 in sequence before entering the vehicle. The air is purified after passing through the filter and activated carbon layer 4, and then carries fragrance after passing through the fragrance module 5, thus purifying the air inside the vehicle.

[0047] Understandably, during the air purification process, the temperature sensor 11 detects the temperature inside the vehicle in real time, and the control unit 9 controls the semiconductor cooling chip 7 to work, so that the temperature inside the vehicle is maintained within the set threshold range. This achieves air purification while maintaining the temperature inside the vehicle.

[0048] In this embodiment, as Figure 4 As shown, when the power output of the solar thin-film battery is not less than the power required by the load (centrifugal fan 6 and semiconductor refrigeration chip 7), the control unit 9 controls the first power supply line assembly to work, using the solar thin-film battery 1 to supply power to the semiconductor refrigeration chip 7 and centrifugal fan 6 in a direct supply mode, while the solar thin-film battery 1 charges the capacitor 10.

[0049] When the power output of the solar thin-film battery is less than the power required by the load (centrifugal fan 6 and thermoelectric cooler 7), the control unit 9 controls the second power supply line assembly to work, using capacitor 10 to supply power to thermoelectric cooler 7 and centrifugal fan 6. At the same time, the control unit 9 controls the power of thermoelectric cooler 7 and centrifugal fan 6 to be less than the power when the solar thin-film battery 1 is directly powered. The specific power level can be determined according to the actual working conditions, which will not be described in detail here.

[0050] In this embodiment, when there is sufficient sunlight during the day, the power generation of the solar thin-film battery meets the requirements and can be used to supply power while charging the capacitor 10. When there is insufficient sunlight at night, the power generation of the solar thin-film battery does not meet the load power requirements, and the capacitor 10 can be used to supply power. The entire system can work 24 hours a day without interruption and can work without starting the vehicle. The capacitor 10 is charged by the solar thin-film battery 1, which is the only power source and does not require additional power consumption.

[0051] Example 3 This embodiment provides a car equipped with the in-vehicle environment control system described in Embodiment 1, such as... Figures 5-6 As shown, the solar thin-film battery 1 is integrated between the inner layer 201 and the outer layer 202 of the automotive sunroof 2 glass. The integrated structure of the inner layer 201, the outer layer 202 and the solar thin-film battery 1 of the sunroof 2 is installed on the outer panel 17 of the vehicle roof and is fixedly connected to the outer panel 17 of the vehicle roof by glass glue 18. A sunroof strip 19 is provided between the sunroof 2 and the outer panel 17 of the vehicle roof.

[0052] The housing 13 of the environmental control mechanism is fixed to the roof trim panel 14 by fasteners. The roof trim panel 14 and the interior roof 15 are snapped together onto the body roof reinforcement plate 16. The body roof reinforcement plate 16 is welded and fixed to the body roof outer panel 17.

[0053] In this embodiment, screws are used as fasteners. It is understood that bolts or other fasteners can also be used as fasteners. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0054] In this embodiment, the outer panel of the vehicle roof, the roof trim panel, the interior roof, the reinforcing plate of the vehicle roof, and their connection methods can all be achieved using existing technologies, and will not be described in detail here.

[0055] The rest of the car's structure can be achieved using existing technology, and will not be described in detail here.
