Description

Electronics

The present invention relates to an electronic device in which an opening / closing portion rotates around a hinge portion to open / close the device main body.

For example, a vehicle-mounted display device used for rear seat entertainment (RSE) or the like has its housing body attached to the ceiling of the vehicle, and the display panel rotates around the hinge portion to open and close the device body. As described above, since the display panel opens and closes, in order to electrically connect the internal configurations of the display panel and the apparatus main body, a flexible cable that can be bent in accordance with the movement of the display panel is used.

A flexible wiring member such as a flexible cable can be bent freely, but if its movement is restricted in a spatially narrow location, stress will concentrate on the same location each time the opening and closing part moves. There is a risk of disconnection.
As a conventional technique proposed to solve such a problem, there is an electronic device disclosed in Patent Document 1, for example. In this electronic device, in order to prevent stress from concentrating on a part of the flexible cable that electrically connects the movable panel and the device main body, the bending of the flexible cable according to the operation of the movable panel is allowed. An auxiliary plate that always forms a margin is provided.

In addition, the conventional in-vehicle display has a flexible design similar to the flexible cable so that the flexible cable is not exposed from the gap generated between the display panel and the device body when the display panel is opened. There may be a case where a sheet member is provided. One end of the sheet member for design is connected to the inside of the display panel, and the other end is connected to the inside of the apparatus main body to shield the flexible cable from the gap.

JP 2005-197419 A

In a conventional electronic device, with the display panel closed, the design sheet member is attached from the device main body to the display panel along the sheet surface along each internal shape. For this reason, the design sheet is applied by a force to bend the design sheet member that works when the relative positions of both ends of the design sheet member change from the state in which the display panel is opened and the display panel is closed. Excessive bending occurred in the member.
The excessive bending of the design sheet member may push the flexible cable into the gap between the display panel and the device body (the gap on the opposite side of the design surface). In this case, the stress generated by the opening and closing operation of the display panel Concentrating on the portion pushed into the gap, there was a possibility that the breakage of the flexible cable or the crack in the design sheet member occurred.

In addition, although the conventional technique which concerns on patent document 1 can always form the allowance of the bending | flexion which accept | permits the movement of a flexible cable with an auxiliary | assistant plate, it originated in the excessive bending of the above-mentioned sheet | seat member for designs. The failure of the flexible cable is not considered. For this reason, in the invention which concerns on patent document 1, the said subject cannot be solved.

The present invention was made to solve the above-described problems, and an object of the present invention is to obtain an electronic device that can prevent the occurrence of problems such as disconnection of a flexible cable that connects an opening / closing portion and a device body.

An electronic apparatus according to the present invention electrically connects an apparatus main body, an opening / closing section that pivots about a hinge section to open / close the apparatus main body, an internal component of the opening / closing section, and an internal component of the apparatus main body. One end is connected to the inside of the opening / closing part and the other end is inside the equipment body so as to shield the wiring member from the gap between the wiring member having flexibility and the opening / closing part and the device body. In an electronic apparatus comprising a flexible design sheet member that is connected and attached, the design sheet member is formed with a curved bent portion on at least one end side in a state where the opening / closing part is closed. It is characterized by being pulled around and attached.

According to the present invention, there is an effect that it is possible to prevent the occurrence of problems such as disconnection of the flexible cable connecting the opening / closing part and the device main body.

The in-vehicle display 1 shown in FIG. 1 can be opened and closed with respect to the device main body 4 by rotating the display panel 2 around the hinge portion. Further, the internal components of the display panel 2 and the internal components of the device body 4 are electrically connected via a flexible cable or the like that is a flexible wiring member. Examples of the flexible wiring member include a flexible printed cable in which a wiring pattern is formed on a resin film, or a flat cable in which a plurality of coated conductors are joined together in a strip shape. Hereinafter, the wiring member is referred to as a flexible cable.

When the display panel 2 is completely closed, as shown in FIG. 1A, the display panel 2 is fitted in the concave portion of the cover 3 that covers the device body 4, and the flexible cable as the internal wiring is exposed to the outside. There is no. However, in the state where the display panel 2 is opened, as shown in FIG. 1B, from the gap generated between the end side portion 2b along the axial direction of the hinge portion of the display panel 2 and the device main body 4, The internal flexible cable may be exposed.

In particular, when the vehicle-mounted display 1 is a ceiling-mounted display that attaches the device body 4 to the ceiling of the vehicle, the passenger in the rear seat looks up at the display screen 2a from diagonally below the display panel 2. . If the display screen 2a is viewed from its normal direction, the gap is hidden by the cover 3 and is difficult to see. However, when the display screen 2a is looked up obliquely from the lower side of the display panel 2, the occupant takes the display screen 2a. In addition, the gap is also visible.
For this reason, conventionally, one end is connected to the inside of the display panel 2 so that the flexible design sheet member shields the flexible cable from the gap between the display panel 2 and the device body 4, The other end is connected and attached to the inside of the device body 4.

FIG. 2 is a cross-sectional view showing a sheet member for design and a flexible cable in a conventional electronic device. A cross-section of a conventional in-vehicle display taken along line AA in FIG. 1 is taken from the direction of arrow B in FIG. FIG. As shown in FIGS. 2A and 2B, the flexible cable 5 is mounted on the connector 5 a mounted inside the chassis 7 in the display panel 2 and the substrate 8 in the device body 4. The electronic components inside the chassis 7 and the electronic components on the board 8 are electrically connected via the connector 5b.

Further, in the conventional in-vehicle display, as shown in FIG. 2 (a), with the display panel 2 closed, the sheet surface is aligned along the internal shape from the device body 4 to the display panel 2 for design purposes. A sheet member 6 'is attached. The flexible cable 5 is in a state along the shape of the end side 2b together with the design sheet member 6 '.

When the display panel 2 is opened from this state, the relative positions of both ends of the design sheet member 6 ′ are changed from the state in which the display panel 2 is closed, and a force that bends the design sheet member 6 ′ acts. Due to this force, as shown in FIG. 2B, excessive bending occurs in the design sheet member 6 ′.
This excessive bending may push the flexible cable 5 into the gap 9 (gap opposite to the design surface) between the display panel 2 and the device main body 4, and in this case, the movement of the flexible cable 5 is restricted. The stress concentrates on the portion pushed into the gap 9.
For this reason, if opening and closing of the display panel 2 is repeated, the flexible cable 5 may be disconnected, and further, the design sheet member 6 ′ that has pushed the flexible cable 5 into the gap 9 may be cracked. there were.

Therefore, in the present invention, the design sheet member is drawn and attached so as to form a bent portion in which at least one end side is curved in a state where the display panel is closed.
By comprising in this way, the force which is going to bend the design sheet | seat member which works when a display panel opens is absorbed by the said curved bending part. For this reason, excessive bending does not generate | occur | produce in the sheet | seat member for designs, and the malfunction mentioned above can be prevented.

Thus, the design sheet member 6 is drawn around and attached. 3A, the design sheet member 6 is routed so that a bent portion curved to the opposite side of the hinge portion of the display panel 2 is formed.
By attaching the design sheet member 6 in this way, the force to bend the design sheet member 6 that works when the display panel 2 is opened is absorbed by the curved bent portion. As a result, as shown in FIG. 3B, the curved bent portion on the device main body 4 side becomes large, but excessive bending toward the gap 9 between the display panel 2 and the device main body 4 is formed. Therefore, it is possible to prevent the occurrence of defects due to excessive bending.

In addition, in FIG. 3, although the aspect which forms the bending part curved beforehand in the edge part by the side of the apparatus main body 4 of the sheet | seat member 6 for designs was shown, this invention is not limited to this.
For example, the bending portion becomes large when absorbing the force that acts when the display panel 2 is opened. Therefore, when the space that allows this is on the display panel 2 side, the bent portion is curved at the end on the display panel 2 side. It may be attached by being routed so that a bent portion is formed, or may be attached by being drawn so as to form a bent portion bent on both the display panel 2 side and the device main body 4 side.
