That is, when the switch unit 90 provided on the front surface of the door unit 20 is turned on to output an operation signal, the operation signal is transmitted to the control unit 100. The control unit 100, ).

 The compressor 50 transfers the air generated by the operation to the pressure tank 60 and the valve 80 and supplies the compressed air to the tube 30 through the mounting socket 31.

The tube 30 is inflated inside the tube seating portion 22 by the air supplied in this manner to seal the boundary between the side case 10 and the door portion 20.

Therefore, it is possible to prevent the inflow of rain or the like into the inside, thereby stably protecting the electric equipment provided in the side case 10.

The compressor 50, the pressure tank 60, and the valve 80 are connected via an air transfer line (not shown).

In the case of the compressor 50, an operation signal is received from the control unit 100 to produce air and supply it to the pressure tank 60. The pressure tank 60, which receives air from the compressor 50, It is stored and transferred to the valve 80.

A pressure sensor 70 is installed inside the pressure tank 60 to continuously measure the internal pressure and transmit the measured value to the controller 100. The pressure sensor 70 is disposed inside the pressure tank 60 More than necessary air is supplied to the pressure tank 60 to prevent the pressure tank 60 from being damaged by the internal pressure and to elastically control the operation of the compressor 50. [

Accordingly, it is possible to prevent the tube 30, which has been continuously supplied with the air from the tube 30, from reaching the limit point, and to prevent the unnecessary power from being consumed (wasted).

The air from the pressure tank 60 is supplied to the air transfer line through the valve 80. The valve 80 is composed of a conventional 2-way sol-valve, ).

Since the 2-Way Sol-Valve is a well-known technique, a detailed description thereof will be omitted.

The operation of the door unit 20 will be briefly described. When the switch unit 90, which is installed on the front surface of the door unit 20, is turned off by pressing the switch unit 90, a control signal is outputted through the switch unit 90, And is transmitted to the control unit 100.

The control unit 100 receives the air and controls the valve 80. At this time, the air transfer path is changed by the solenoid, and the expanded tube 30 is supplied with the air by the changed transfer path, And the discharged air is discharged to the outside through the path of the changed valve 80.

For reference, a portion indicated by a dotted line in FIG. 4 shows an electrical signal, and a portion indicated by a solid line shows a flow of air.

This allows opening of the door portion 20 which could not be opened by the tube seating portion 22 and the bulged tube 30 and allows the door seat portion 22 and the tube 30 to function as a detaching mechanism So that even if a person other than the occupant turns the handle 21, the door 20 can not be opened easily, so that the door 20 can be safely protected from electric safety accidents.

Hereinafter, the operation of the present invention will be described.

The door 20 is closed by turning the handle 21 in a state in which the door 20 is in close contact with the front surface of the side case 10, (90) to turn on (turn on).

The control unit 100 controls the compressor 50, the pressure sensor 70 and the valve 80 while the switch unit 90 is turned on.

More specifically, the compressor 50 operated by the control unit 100 itself generates air and supplies the air to the pressure tank 60. The pressure sensor 70 detects the internal pressure of the pressure tank 60 And transmits it to the controller 100. [

The valve 80 is changed by the solenoid so that the discharge line (not shown) of the pressure tank 60 and the air transfer line (not shown) are communicated with each other so that air is naturally moved along the air transfer line.

The tube 30 is inflated inside the tube seating portion 22 by the air continuously supplied through the mounting socket 31 to seal the boundary portion between the side case 10 and the door portion 20 .

The boundary between the side case 10 and the door part 20 is sealed by the tube seating part 22 and the tube 30 to prevent the entrance of rainwater into the inside.

When the door unit 20 is to be opened, the switch unit 90 disposed on the front surface of the door unit 20 is turned off again to control the operations of the compressor 50 and the valve 80.

The tube 30 controlled by the control unit 100 is changed in its path by the solenoid and the tube 30 which can not continuously receive the air is contracted by the elastic restoring force, And is discharged to the outside through the valve 80 through the transfer line.

This is because when the door unit 20 is opened and the compressor 30 is stopped under the control of the controller 100 according to the OFF signal of the switch unit 90, The door 20 can not be opened quickly due to the state of being coupled to the tube seating part 22 while the expansion state of the door 20 is maintained for a predetermined time.
When the door unit 20 is closed, the pressing unit 110 maintains the shrunk state because the grip unit 21 is in the locked state as well as the driving force of the compressor 50. At this time, It can be understood that the door part 20 can perform a sealing function and a locking function with the side surface conductive case 10.

The tube seating part 22 is preferably formed with a coupling groove 22a through which the front end of the spring 111 is inserted.

The pressing unit 110 may further include a support cap 112 coupled to a front surface of the spring 111.

The support cap 112 may be fitted into the coupling groove 22a.

Alternatively, the coupling groove 22a may be formed with a thread on the inner circumferential surface thereof, and the support cap 112 may be screwed into the coupling groove 22a while forming a thread on the outer peripheral surface thereof.

The pressing unit 110 may further include a pressure cap 113 coupled to a rear surface of the spring 111 and in contact with the tube 30.

The pressing cap 113 includes a cover 113a whose front surface is opened and a rear portion of the spring 111 is fitted to the inside and a pressure plate 113b provided on the rear surface of the cover 113a.

The pressure plate 113b is preferably formed larger than the diameter of the cover 113a.

As the air is supplied to the tube 30, the cover 113a is retracted by the expansion of the tube 30 and is drawn into the support cap 112 while being contracted.

It can be understood that the degree of protrusion from the inside of the tube seating part 22 is minimized in accordance with the expansion of the tube 30.

The present invention provides an auxiliary pressing means 120 for pressing the door portion 20 from the mounting portion 11 and opening the door portion 20 smoothly according to the opening of the door portion 20 .

The auxiliary urging means 120 includes a plurality of coil springs 121 provided between the door portion 20 and the mounting portion 11.

The coil spring 121 is preferably disposed on the other side of the hinge-coupled portion between the door portion 20 and the mounting portion 11 in the vertical direction.

For example, the door portion 20 has a rear surface formed with a coupling groove 20a to which a front surface portion of the coil spring 121 is coupled, and the mounting portion 11 has a door portion 20, And a lead-in groove 11a into which the rear portion of the coil spring 121 is inserted may be formed.
