Description

AUTOMATIC VENTILATION SYSTEM OF VEHICLES}

The present invention relates to an automatic ventilation system of a vehicle. In particular, when the temperature inside the vehicle rises above the set temperature in a state in which the vehicle is turned off, the vehicle is forced to supply air to the inside of the vehicle, thereby lowering the vehicle temperature It is a technology related to an automatic ventilation system of a vehicle that can promote the safety of passengers.

The vehicle has a structure in which the battery body is supplied with a metal body as well as all the functions of the vehicle being inserted into the vehicle's ignition box.

Therefore, in the related art, when a key is removed from a key box of a vehicle, the function of the vehicle is completely stopped, and thus large and small accidents frequently occur.

In particular, when the vehicle is parked in a roadside parking lot for a long time in the summer season, the internal temperature of the vehicle increases rapidly according to the metal characteristics of the vehicle body. Due to the inconvenience of not being able to drive the vehicle immediately and opening the vehicle door for a predetermined time to perform ventilation.

In addition, it is difficult to request help from the outside, such as preschool children or infants, there is a problem that frequently leads to death accidents when exposed to high temperatures in the interior of the vehicle for a long time while still in the vehicle.

In addition, when the vehicle is parked in a street parking lot with a flammable material (for example, a disposable lighter) placed in a vehicle interior, a closed end at which the combustion of the vehicle occurs while the flammable material bursts from a rapidly rising room interior temperature. This followed.

In order to solve this problem, even if the vehicle is turned off, the technology to lower the indoor temperature by ventilating the indoor air according to the temperature of the vehicle interior,

Republic of Korea Utility Model Registration No. 20-0267923 (registered Feb. 28, 2002, hereinafter referred to as 'Document 1') `` Automatically ventilated vehicle interior according to the start-off '' is proposed,

Document 1 has a sensor for detecting the indoor temperature according to the on / off of the start switch in the interior of the vehicle, and a heat collecting plate for collecting solar energy and an energy conversion unit for converting solar energy into electrical energy is installed on the exterior panel of the vehicle, Inside the vehicle body, a power supply unit for charging and discharging according to the electric energy converted from the energy conversion unit, and an intake motor and a fan and an exhaust motor and fan for driving to forcibly ventilate the temperature in the vehicle room from charge and discharge of the power supply unit. When the vehicle is turned off and the power supply of the battery is completely shut off, when the vehicle is parked in the on-street parking lot (especially summer) for a long time, the detected indoor temperature may be overheated after detecting the temperature of the vehicle interior. In this case, the temperature can be automatically lowered to prevent accidents due to high temperatures (e.g. bursting disposable lighters). In addition, the present invention relates to a device for automatically ventilating an interior of a vehicle according to a start-off, which can solve the discomfort when riding a vehicle parked for a long time.
