DETAILED DESCRIPTION

An auto return structure of a luggage room screen according to an exemplary embodiment of the present invention is a technique, which makes it possible to perform auto return of the screen through improvement of a guide portion200that is formed in a luggage side trim and an end portion331of a reinforcement board330of a screen device300that is movably installed in the guide portion200.

The auto return structure of a luggage room screen according to an exemplary embodiment of the present invention, as illustrated inFIGS. 1 and 2, includes the guide portion200formed on a luggage side trim100that is an inner wall surface of a luggage room, and the screen device300which is installed across the luggage room in the left/right direction (in the vehicle width direction) of a vehicle body and is installed along the guide portion200if necessary in a state where a screen is inserted into the guide portion200.

The guide portion200has a structure that makes the screen drawn out from the screen device300automatically returned, and includes a guide groove210, a movement groove220, and a locking protrusion240.

The guide groove210is to guide the end portion331of the reinforcement board330toward the rear of the vehicle body, and is formed to connect to the luggage side trim100toward the rear of the vehicle body. The end portion of the reinforcement board is movably installed in the guide groove, and an end of the guide groove210is formed to be gradually inclined toward the lower part of the vehicle body.

That is, the end portion of the guide groove210is formed to be bent toward the lower part of the vehicle body as being smoothly curved toward the rear of the vehicle body.

The movement groove220is formed to extend from the upper and lower surfaces212and214of the guide groove210to an upper part of the vehicle body, and more particularly, to extend in the form of a semicircle toward the upper part of the vehicle body.

Here, on the lower connection portion of the movement groove220and the guide groove210, a lower support portion211is formed to project in the inner direction (in the upper direction as seen inFIG. 3), and the lower support unit211is positioned on the vertical line of the locking protrusion240.

The lower support portion211as described above locks the return of the end portion331of the reinforcement board330that moves to the guide groove210along the movement groove220, and thus safe operation is guided with the speed reduced.

The locking protrusion240is formed to project to the upper connection portion of the guide groove210and the movement groove220in the rear direction (toward the rear of the vehicle body).

Here, the locking projection240is formed to be downwardly inclined at a predetermined angle, and through this, the end portion331of the reinforcement board330that is locked on the locking protrusion240is easily rotated to facilitate the secession of the locking protrusion.

On the other hand, on the upper connection portion of the movement groove220and the guide groove210, an upper support portion221is formed to project in the inner direction (in the lower direction as seen inFIG. 3), and the upper support unit221supports the end portion331of the reinforcement board330that is moved to the movement groove220, and makes the locking protrusion240and a locking groove332positioned substantially on the same line, and thus guides the end portion331of the reinforcement board330to be inserted into the locking protrusion240.

In an exemplary embodiment of the present invention, the locking groove332may be formed by an upper leg350and a lower leg355wherein the locking groove332is disposed therebetween.

The screen device300, as illustrated inFIG. 2, is provided in the luggage room, and is installed across the luggage room in the left/right direction (in the vehicle width direction) of a vehicle body. The screen device300includes a screen housing310fixed to the luggage side trim100, a screen320which is wound on a rotary roll in the screen housing310and is drawn through an outlet of the screen housing310, and the reinforcement board330which is connected to the front end of the screen320and the end portion of which is movably installed in the guide portion200.

The rotary roll has an elastic restoring force by a spring, and thus the screen320wound on the rotary roll is maintained unless an external force is applied thereto.

Here, the end portion331of the reinforcement board330includes a vertical surface and a curved surface in the form of a semicircle, and the locking groove332is formed on the vertical surface so that the locking protrusion240is inserted into the locking groove332.

On the other hand, the interlocking groove332formed on the reinforcement board330and the locking protrusion240of the guide portion200are positioned to correspond to each other.

The auto return structure of the luggage room screen as constructed above, as illustrated inFIG. 3, has an inclination angle a° of the locking protrusion240, an inclination angle b° of the lower support portion211connected to the guide groove210, an inclination angle c° of the movement groove220connected to the lower support unit211, and an inclination angle d° from the upper support portion221to the lower support portion211around the locking protrusion240(where, a°<b°<c°<d°).

That is, the inclination angle a° of the locking protrusion240is formed to be inclined downwardly from the ground, and the upper surface of the locking groove332is formed to be inclined at the same angle so that the upper surface of the locking groove332becomes in close contact with the inclined angle a° of the locking protrusion240.

The inclination angle b° of the lower support portion211connected to the guide groove210is formed to be larger than the inclination angle a° of the locking protrusion240, and thus the locking force of the end portion331of the reinforcement board330is increased.

Also, the inclination angle c° of the movement groove220connected to the lower support unit211is formed to be larger than the inclination angle b° of the lower support portion221, and thus the end portion331of the reinforcement board330is prevented from being caught in the groove.

Also, the inclination angle d° from the upper support portion221to the lower support portion211around the locking protrusion240is formed to be larger than the inclination angle c° of the movement groove220connected to the lower support unit211. Considering that the end portion331of the reinforcement board330can secede from the locking protrusion240if the end portion331of the reinforcement board330locked on the locking protrusion240is sufficiently rotated as large as the inclination angle d°, the end portion331of the reinforcement board330fixed to the locking protrusion240is prevented from seceding due to the self-movement.

The operation of the auto return structure of a luggage room screen as constructed above will now be described with reference toFIG. 4.

As illustrated inFIG. 4, if a user pulls the reinforcement board330toward the rear of the vehicle body in a state where the user holds the reinforcement board330, the end portion331of the reinforcement board330is moved to the movement groove220along the guide groove210. At this time, the screen320is drawn out from the screen housing310along the reinforcement board330to finish the upper portion of the luggage room.

Then, the end portion331of the reinforcement board330is supported by the upper support portion221, and the locking protrusion240is locked in the locking groove332of the reinforcement board330.

In particular, the upper leg350is coupled between the locking protrusion240and the upper support portion221. The mass center340of the end portion331is biased upward the mass center245of the locking protrusion240, such that the end portion331is biased upwards and thus the upper leg350is firmly coupled between the locking protrusion240and the upper support portion221.

Then, the end portion331of the reinforcement board330is fixed to the locking protrusion in a locked state by the elastic restoring force acting on the screen that is wound on the rotary roll.

Then, in the case of removing the screen320that has finished the upper portion of the luggage room, if the reinforcement board330is pressed, the end portion331of the reinforcement board331is rotated in the lower direction around the locking protrusion240. In this case, if the rotating angle of the end portion331becomes equal to or larger than the inclination angle d°, the center of gravity is changed, and the end portion331of the reinforcement board330is automatically moved along the guide portion200as indicated by dotted line inFIG. 4to make the screen320drawn into the screen housing310.

In this case, if the end portion331of the reinforcement board330is moved from the movement groove220to the guide groove210, the movement radius of the reinforcement board330is minimized as the end portion331is supported by the lower support portion221, and thus a prompt return can be guided.
