technical field

The invention relates to a seat in the technical field of vehicles, in particular to a car seat that does not heat up in the sun.

Background technique

With the continuous progress of society, the rapid development of science and technology, and the rapid development of the automobile industry, more and more families have their own cars, and people have higher and higher requirements for the comfort of the car environment. In the hot summer, the temperature of a car parked under the sun for a long time is relatively high, and the surface temperature of the seat in the car can even reach a hot level, which brings great discomfort to the occupants. There is an air-conditioning system to adjust the temperature inside the car, but this adjustment method will cause the seats to become hot when the car is stopped, and this adjustment method is relatively slow. The temperature of the seat surface decreases, which makes it difficult to meet the comfort requirements of the seat when people get on the bus.

In order to meet the higher requirements of the occupants for seat comfort, in recent years people have attempted to adjust the comfort of the occupant's back and buttocks by adjusting the surface temperature of the seat. After searching, the Chinese Patent Publication No. CN2543761Y, the name of the utility model is: seat temperature adjustment device; this technology proposes to put the evaporation pipe device in the seat cushion and the backrest, and use the existing air conditioning system of the car to connect the evaporation pipe to realize the car seat. The temperature adjustment of the car seat, but this technology can only play its role when the original air-conditioning system of the car is turned on. When the car air-conditioning system stops running, the temperature of the car seat cannot be controlled; the Chinese patent publication number is CN201002544Y, the name of the utility model It is: air-conditioned car seat; this technology proposes a kind of air-conditioned car seat with heating and cooling functions. The way of the electric heating seat is similar, and it is necessary to install multiple air guide pipes and air guide vanes, and also need to install multiple axial flow fans in the air guide pipe, the structure is complex and the cost is relatively high. The Chinese patent publication number is CN101249811A, and the utility model name is: thermoelectric car air-conditioning seat. This technology uses the car power to drive the thermoelectric module alone, which can realize the independent operation of car seat cooling/heating, but due to the limitation of the battery power when the car is stopped, the time of independent operation is very short, which cannot solve the problem of car seat cooling/heating when the car is parked for several hours. The problem of the temperature rise of the seat, and the waste heat directly discharged into the car will have a certain impact on the occupants of the car.

It can be seen that although the above-mentioned schemes have realized the adjustment of the seat temperature to a certain extent, it is difficult to solve the problem of seat scalding, especially when the car is parked; and they all rely on the electric drive of the car power supply. , the storage capacity of the battery is limited. Compared with the prior art, the present invention utilizes solar energy to drive semiconductor chips for cooling/heating, uses an energy storage device to store energy, and starts the seat device to work according to the operating mode on the remote control of the car, and parks in a short period of time, such as outdoors for a short period of time , you can choose the sun-free mode, use solar energy to drive semiconductor refrigeration, and turn on the air supply and exhaust fans to force convection to achieve continuous cooling of the seat and keep the seat temperature within a comfortable range; when the car is parked for a long time For example, one or two hours or more, you can choose the energy storage quick cooling mode. In the early stage, the cooling provided by the solar-driven semiconductor chip is stored in the energy storage device. The fan at the air supply end is turned off, and the air supply is turned on before the personnel get on the car. The end fan transfers the cold energy in the energy storage box to the seat surface, quickly reducing the temperature of the seat; when the car stops for a long time, the power storage mode can be turned on, and the solar photovoltaic power is directly stored in the car battery; the non-active cooling mode It is the auxiliary cooling mode of the above-mentioned modes. When the temperature inside the car is suitable, only the fan at the air supply end of the car seat that is not heated by the sun can be turned on, and the cold air in the car can be used to achieve partial cooling of the seat. The above-mentioned modes can be selected according to individual needs, and there is no exact time limit. The invention can use solar photovoltaic to drive thermoelectricity to provide seat cooling/heating, does not rely on the power supply of the car battery, and can continuously and effectively keep the car seat comfortable.

The air outside the seat is sucked in through the inlet of the air duct, and exchanges heat with the cooling fins, and the treated air is blown to the seat surface through the perforated seat skin. The thermoelectric heat pipe cooling device includes a heat pipe and a set of heat dissipation fins. A fan for accelerating heat dissipation is installed at the lower end of the heat dissipation fins. The thermoelectric heat pipe heat dissipation device is connected with a heat preservation air outlet pipe leading to the air outlet of the car for dissipating waste heat. , to avoid the impact on the personnel and the environment in the car.

To meet the comfort requirements of personnel, the energy storage device is used to store energy to meet the large cooling capacity required to cool the seat instantly, and when the temperature of the seat is lowered, the cooling capacity required to maintain the comfort of the seat is small. At the same time, the use requirements are met through the continuous work of the semiconductor chip. The specific implementation method is: when cooling is required, solar photovoltaic cells are used to generate electricity, the car is parked for a short time, and the mode of running in the sun can be selected to keep the semiconductor chip 302, the fan 403 at the air supply end, and the fan 505 at the cooling end turned on, and the semiconductor chip 302 is turned on by the solar energy. Cooling is driven by photovoltaic cells, and the fan 403 at the air supply end is turned on to force convection to draw the air in the car from the air inlet 201, and use the cooling generated by the semiconductor to exchange heat with the air at the first heat dissipation fin 404 through the heat pipe.
