Description

Trunk opening and closing device for vehicle {Control system of trunk}

The present invention relates to a trunk opening and closing device of a vehicle, and more specifically, to install a pneumatic cylinder between the trunk lid and the body and to drive the air compressor using the engine power of the car to inject the compressed air into the pneumatic cylinder The compression device relates to a trunk opening and closing device of a vehicle in which the operation is controlled by a switch installed in the vehicle or the trunk lid, so that the trunk is opened and closed by the operation of the switch.

In general, a trunk for loading a load is formed at the front end or the rear end of the vehicle body, and an example thereof will be described with reference to FIG. 1.

1 is a side view showing a conventional trunk opening and closing structure, the trunk (2) is controlled by opening and closing the trunk lid (6) coupled to the fastening bar (4) to the vehicle body, the trunk is generally installed on the driver's side In order to operate the lid opening lever (not shown), or to directly open the trunk lid 6 by hand, and to close the trunk 2, it was necessary to press the trunk lid 6 by hand.

However, according to the conventional trunk opening and closing structure as described above, when the trunk (2) is opened, the trunk (2) is always in full bloom, so that the opening amount of the trunk (2) is not adjusted so that the trunk (2) like the bicycle is opened. When loading a cargo that cannot be closed, it was inconvenient to fasten the trunk lid to the body by using a strap or the like to prevent the cargo from falling off. The trunk (2) that is opened is closed only when the trunk lid (6) is pressed directly. In order to close), people had to move to the trunk (2) position directly.

An object of the present invention for solving the above problems is to install a pneumatic cylinder between the trunk lid and the body and to install an air compressor using the engine power of the vehicle inside the body of the vehicle, the air compressor and the pneumatic cylinder The solenoid valve is connected to a pipe line in which a solenoid valve is installed, and the solenoid valve is controlled by an on / off switch provided in the vehicle interior or the trunk lid. It is to provide a trunk opening and closing device of a vehicle that closes the trunk by opening it, or by closing the trunk at a desired point, or by letting the air of the cylinder out through the solenoid valve.

An embodiment of the present invention for achieving the above object will be described with reference to the accompanying drawings.

Figure 2 is a side view showing a trunk opening and closing device according to the present invention, Figure 3 is a side view showing an open state of the trunk in the trunk opening and closing device according to the present invention.

Trunk opening and closing device of the vehicle according to the present invention is a pneumatic cylinder (26) hinged to both ends of the trunk lid 22 and the body 24, respectively, and installed in the body of the vehicle and driven by the engine power of the vehicle The air compressor 28, the pipeline 30 for connecting the air compressor 28 and the pneumatic cylinder 26, the first switch 34 for opening and closing the trunk installed in the vehicle, and the trunk lid ( 22 and a second switch 35 outputting the same signal as the trunk opening and closing switch 34 according to the rotation of the vehicle key, and the plurality of switches 34 and 35 installed in the conduit 30. The compressed air of the air compressor 28 to the pneumatic cylinder 26 while the switches 34 and 35 are on, and the pneumatic cylinder while the switches 34 and 35 are off. 26 is composed of a solenoid valve 36 for discharging the air to the outside.

On the other hand, in the above configuration, the air compressor 28 is a structure that is applied to and used in large vehicles, the detailed description and drawings will be omitted.

Looking at the embodiment of the trunk opening and closing device of the vehicle according to the present invention configured as described above.

First, when the trunk is to be opened, the first switch 34 installed inside the vehicle is turned on or a key is inserted into the second switch 35 of the trunk lid 22 to rotate in a specific direction (for example, to the right). The solenoid valve 36 supplies the compressed air of the air compressor 28 into the pneumatic cylinder 26, whereby the trunk lid 22 is gradually lifted from the body 24 by the pneumatic cylinder 26. The trunk 40 is opened. At this time, the opening degree of the trunk 40 is controlled according to the operation of the solenoid valve 36, so that the trunk lid 22 is raised only during the time when the operator turns on the switches 34 and 35. Therefore, the opening and closing degree of the trunk 40 can be controlled.

In order to close the opened trunk 40, when the first switch 34 is turned off or the second switch 35 is rotated in the opposite direction (left side), the solenoid valve 36 is operated in the pneumatic cylinder 26. Air is discharged to the outside, and in this process, the lowering degree of the trunk lid 22 is controlled according to the off state of the switches 34 and 35 in the same manner as the opening of the trunk 40. The degree is controlled.

On the other hand, after the trunk lid 22 is lowered to close the trunk 40 as described above, since the inside of the pipeline 30 is maintained in a vacuum state, the trunk lid 22 is raised while driving, that is, the trunk 40 is closed. The opening phenomenon does not occur.

Therefore, according to the present invention, the trunk can be opened and closed in a car, so it is free to open and close the trunk in a situation where it is difficult to move outside the vehicle such as in the rain or a disabled person, and the opening and closing degree of the trunk is controlled, so that the size of the trunk is greater than that of a trunk, Even when carrying a rather large cargo there is an effect that the inconvenience of connecting the trunk lid and the body with a string as in the prior art does not occur.
