Description

  The present invention relates to a display device mounted on a mobile device such as an automobile or an aircraft, and a mobile device mounted with the display device.

  For example, in mobile devices such as automobiles and airplanes, a rear seat display device is embedded in the upper back side of the front seat. In this way, on the upper back side of the front seat, When a seating device is embedded, the orientation of the display device cannot be changed greatly.

  Therefore, it is conceivable that the display device is attached to the back side of the front seat using the attachment shaft.

  However, if the display device is mounted in an exposed state in this way, the exposed display device may be dangled or dangled by, for example, a child. Therefore, in order to increase the strength of the display device, And the cover that covers the back side must be made of a strong metal case.

  However, if the cover is made of a strong metal case, the weight becomes heavy, and in a mobile device such as an automobile or an aircraft, it is not preferable in view of safety at a sudden stop.

  Therefore, it is conceivable that the cover is made of carbon fiber reinforced plastic (Carbon Fiber Reinforced Plastics).

JP 2005-149463 A

  As described above, when the cover is formed of carbon fiber reinforced plastic, the strength is high and the weight is light. Therefore, even a display device exposed from the front seat does not cause a safety problem.

  However, since the carbon fiber reinforced plastic is hard and brittle, at the contact portion between the cover and the mounting shaft, the mounting shaft is damaged or a part of the carbon fiber reinforced plastic is missing.

  In addition, since carbon fiber reinforced plastic is conductive, if this piece penetrates into the cover, it may cause inadvertent electrical problems such as a short circuit of an electronic circuit.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent the cover and the mounting shaft from being damaged and to prevent the occurrence of inadvertent electrical problems.

In order to achieve this object, the present invention provides a display unit, a cover that covers the outer peripheral side or the back side of the display unit, and a cover that is provided in the cover and is electrically connected to the display unit. a control board, the cylindrical attaching the cover to the seat structure adult, or a rod-shaped mounting shaft, said cover thereby forming at carbon fiber reinforced plastic (carbon fiber reinforced plastics), this cover, the attachment An insertion hole for inserting a part of the shaft into the cover is provided, and a cylindrical bearing having one end positioned inside the cover and the other end positioned outside the cover is attached to the insertion hole. Then, a part of the mounting shaft is inserted into the cover, and an exposed portion of carbon fiber is provided on the inner surface of the cover. The exposed portion is electrically connected to at least one of the ground line of the display unit or the ground line of the control board with a conductor, and the outer periphery of the exposed portion of the carbon fiber in the cover is covered with packing, To achieve the intended purpose.

As described above, the present invention provides a display unit, a cover covering the outer peripheral side or the back side of the display unit, a control board provided in the cover and electrically connected to the display unit, and a cylindrical or rod-shaped mounting shaft, attaching the cover to the seat structure adult, carbon fiber reinforced plastic the cover (carbon fiber reinforced
The cover is provided with an insertion hole through which a part of the mounting shaft is inserted into the cover. One end is located inside the cover and the other end is located outside the cover. A cylindrical bearing is mounted, and a part of the mounting shaft is inserted into the cover through a through hole of the bearing, and an exposed portion of carbon fiber is provided on the inner surface of the cover. The exposed portion is electrically connected to at least one of the ground line of the display unit or the ground line of the control board with a conductor, and the outer periphery of the exposed portion of the carbon fiber in the cover is covered with packing. Therefore, damage to the cover and the mounting shaft can be prevented.

That is, in the present invention, the cover is provided with an insertion hole for inserting a part of the mounting shaft into the cover, and the insertion hole has a cylindrical shape with one end positioned inside the cover and the other end positioned outside the cover. Since a part of the mounting shaft is inserted into the cover through a through-hole of the bearing, the carbon fiber is adjusted even when the tilt of the display unit is adjusted. The insertion hole of the cover made of reinforced plastic and the mounting shaft are not rubbed, and as a result, damage to the cover and the mounting shaft can be prevented.

  In the present invention, an exposed portion of carbon fiber is provided on the inner surface of the cover, and the exposed portion is electrically connected to at least one of the ground line of the display unit or the ground line of the control board with a conductor. And the outer periphery of the exposed portion of the carbon fiber in the cover is covered with packing, so that the ground connection of at least one of the ground line of the display unit or the ground line of the control board is made through the cover. Is possible.

  That is, the cover is formed of carbon fiber reinforced plastic, and the carbon fiber inside thereof has conductivity, so that an exposed portion of the carbon fiber is formed on the inner surface of the cover. If the exposed portion is connected to a conductor to at least one of the ground line of the display unit or the ground line of the control board, the ground line of the display unit or the ground line of the control board is connected via the cover. At least one of the ground connections is possible.

  Carbon fiber reinforced plastics have high strength and high elasticity. That is, even if the amount of deformation in the state where force is applied is large, if the weight is lost, the original state is restored. Even in such a case, since the outer periphery of the exposed portion of the carbon fiber in the cover is covered with packing (usually higher elasticity than the carbon fiber reinforced plastic), the carbon fiber is exposed from the exposed portion of the carbon fiber. The conductive powder is not scattered in the cover, and as a result, the occurrence of electrical problems due to the conductive powder can be prevented.

Are electrically connected by a conductor 8c made of a conductive foam.

Therefore, the ground line of the display unit 6 or the ground line of the control board 8b is connected to the conductor 8c, the exposed portion 8a of the carbon fiber, the cover 8, the tension member 24, and the connector 1 through the cover 8.
4, which is mounted shaft 9, to the metal sheet structure adult 2 and ground can be connected.

In order to make such a ground connection, when the end of the tension member 24 is inserted into the attachment portion 25 of the cover 8, the end of the tension member 24 is moved to the carbon fiber constituting the cover 8. it is necessary to (outside of the cover 8 is provided with different exposed portions 8a, it is possible to make the connection between the seat structure adult 2 made of metal by utilizing here).

That is, the cover 8 is made of carbon fiber reinforced plastic, and the carbon fiber inside the cover 8 is conductive. Therefore, an exposed portion 8a of carbon fiber is provided on the inner surface of the cover 8, and the ground line of the display unit 6 or the ground line of the control board 8b is electrically connected to the exposed portion 8a via the conductor 8c. be connected to, via the cover 8, a ground line ground line or control board 8b, the display unit 6, it become possible ground connection to the metallic sheet structure adult 2.

  Carbon fiber reinforced plastics have high strength and high elasticity. That is, even if the amount of deformation in the state where force is applied is large, if the weight is lost, the original state is restored. Even in such a case, the exposed portion 8a of the carbon fiber in the cover 8 is covered with a cylindrical packing 8d provided on the outer periphery thereof (usually higher elasticity than the carbon fiber reinforced plastic). The conductive powder of carbon fiber does not scatter into the cover 8 from the exposed portion 8a of the fiber, and as a result, the occurrence of electrical problems due to the conductive powder can be prevented.
