However, the blocking device includes a sensor 120 'for detecting the door 200', and a controller 130 'for operating the blower 140' according to the signal sensed by the sensor 120 '. In addition to the connection through a separate wiring work, the stopper to supply and cut off the power supply to the wiring should be installed in the door 200 ', when manufacturing the vehicle, the number of parts increases to reduce the assemblability and manufacture of the vehicle There was a problem of raising the unit price.

In addition, conventionally, the sensor 120 ', the controller 130' and the stopper frequently generate a failure due to an impact generated when the door 200 'is opened or closed, so that the air outside the vehicle does not flow into the interior of the cabin. There was a problem that can not function properly.

An object of the present invention, in order to solve the problems as described above, the shutter is rotated to one side and the other side around the hinge according to the self-resilience of the spring and the magnetic state of the electromagnet, and the outlet is opened and closed according to the rotation state of the shutter It consists of a duct, a permanent magnet which generates a magnetic force in the electromagnet so that the exit of the duct is closed, and rotates the shutter to one side, and a door in which the permanent magnet is fixed to the upper part. When the shutter is rotated to the other side around the hinge by the self-resilient force of the spring, the outlet of the duct is opened, and the cooling and heating air supplied from the air conditioning unit is sprayed to the upper part of the opening. This causes the shutter to rotate to one side about the hinge while tensioning the spring and the duct When the air is supplied from the air conditioner by blocking the outlet of the vehicle to be supplied to the compartment, even when the door is opened to install an external air inlet blocker on the bus so that the air outside the compartment is prevented from entering the interior of the compartment In addition, as the number of parts is reduced and the assembly is improved, the manufacturing cost of the vehicle is reduced, and the outlet of the duct is opened and closed by the magnetism of the electromagnet.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail as follows.

External air inflow blocking device of the bus of the present invention, as shown in Figures 3 and 4, one side and the other around the hinge 150 according to the self-resilience of the spring 120 and the magnetic state of the electromagnet 140. To the electromagnet 140 such that the shutter 130 rotates to the side, the duct 110 to open and close the outlet 111 according to the rotation state of the shutter 130, and the outlet 111 of the duct 110 is closed. It is characterized in that the basic configuration in the technical configuration that consists of a permanent magnet 210 for generating a magnetic force to rotate the shutter 130 to one side, and the permanent magnet 210 is fixed to the upper portion.

The present invention configured as described above is installed in the permanent magnet 210 and the shutter 130 installed in the door 200 when the vehicle is driven while the door 200 installed in the opening 220 is closed. As the magnetic force is generated between the electromagnets 140, the shutter 130 is rotated to one side around the hinge 150 to close the outlet 111 of the duct 110, and thus into the vehicle interior through the air conditioner. Outflow of the supplied air is prevented.

In addition, when the occupant in the vehicle opens the door 200 to perform the getting on and off, the permanent magnet 210 is separated from the electromagnet 140 by moving the door 200 to one side, the electromagnet 140 ) Magnetic force is lost.
