In addition, in FIG.1 and FIG.2, these members abbreviate | omit illustration.

  The exterior portion of the display device 1 is formed such that an end corresponding to at least one of the four sides of the rectangle has a cross section including an arc, such as a so-called “round surface” shape or a “crossed surface” shape. Convex shape. In the example of FIG. 1 and FIG. 2, the upper end portion and the lower end portion of the display device 1 are in the form of a round surface. The pivot shaft 12 is constituted by the lower end in the form of a round surface, and the pivot shaft 12 is provided with a magnet 13. The magnet 13 is made of, for example, a permanent magnet such as a ferrite magnet.

  The stand 2 has a substantially rectangular parallelepiped outer shape, and a concave bearing portion 21 is formed on one of six sides of the rectangular parallelepiped. The bearing portion 21 has a concave shape that matches the round surface of the pivot shaft portion 12, and a magnet 22 having a reverse polarity to the magnet 13 of the pivot shaft portion 12 is provided. The magnet 22 is made of, for example, a permanent magnet such as a ferrite magnet.

  As shown by arrow A in the figure, the rotation shaft 12 can be detachably attached to the bearing 21 by the magnetic force of the magnets 13 and 22. In addition, since the bearing portion 21 has a concave shape that matches the round surface of the pivot shaft portion 12, the display device is mounted around the pivot shaft portion 12 in a state where the pivot shaft portion 12 is attached to the bearing portion 21. 1 is rotatable relative to the stand 2.

Next, an example in which the display system 100 is applied to a display device for a rear seat of a vehicle will be described with reference to FIGS. 3 and 4.
As shown in FIG. 3, a stand 2 is attached to the back of the driver's seat 3 of the vehicle. The stand 2 is fixed to the driver's seat 3 by an appropriate fixing means such as a screw or an adhesive (not shown). In addition to the stand 2 of the driver's seat 3, as shown in FIG. 4, the stand 2 is attached to the ceiling 4 of the vehicle. The stand 2 is fixed to the ceiling 4 by an appropriate fixing means such as a screw or an adhesive (not shown). The stand 2 of the driver's seat 3 has the bearing 21 disposed on the upper surface, and the stand 2 of the ceiling 4 has the bearing 21 disposed on the lower surface.

  The display device 1 is detachably attachable to the stand 2 of the driver's seat 3 as shown in FIG. 3 and detachably attachable to the stand 2 of the ceiling 4 as shown in FIG. . Further, the display device 1 is rotatable relative to the driver's seat 3 in a state of being attached to the stand 2 of the driver's seat 3 as shown by arrow B in FIG. 3 and a ceiling as shown by arrow C in FIG. It is rotatable relative to the ceiling 4 in a state of being attached to the stand 2 of the unit 4. The display device 1 shown in FIG. 3 and the display device 1 shown in FIG. 4 are upside down. For this reason, it is preferable that the display device 1 be equipped with a so-called "automatic rotation function" for rotating the screen display of the display unit 11 in accordance with the orientation of the display device 1 main body.

  In addition to the stand 2 of the driver's seat 3 and the stand 2 of the ceiling 4, the stand 2 is also attached to the back of the passenger's seat of the vehicle. The stand 2 is the same as the stand 2 shown in FIG. 3, and the rotation of the display device 1 is also the same as FIG.

  In this manner, by attaching the stands 2 to a plurality of parts of the vehicle and making the display device 1 detachable with respect to each of the stands 2, the display is made according to the number of passengers of the vehicle, the riding position, etc. The mounting position of the device 1 can be made variable, and the degree of freedom of the mounting position can be improved. Further, the number of the display devices 1 included in the display system 100 can be reduced as compared with a structure in which the display devices are fixed to a plurality of parts of the vehicle, and the cost of the display system 100 can be reduced. .

  In addition, by attaching the pivot shaft 12 of the display device 1 to the bearing 21 of the stand 2 and pivoting the display device 1 about the pivot shaft 12, the hinge mechanism is provided on the stand to display the display device. The number of parts of the pivoting mechanism can be reduced as compared to the conventional structure in which the pivoting mechanism is rotated. Moreover, since the assembly of the hinge mechanism is unnecessary in the manufacturing process of the display system 100, the manufacturing cost can be reduced. Furthermore, the stand 2 can be made smaller compared to the conventional structure, and the display system 100 can be made compact. In general, the cabin of a vehicle is limited in space, and compactness of the display system 100 is particularly important.

  Note that the display device 1 may have an end corresponding to a plurality of four sides of the rectangle as the pivot shaft portion 12. For example, as shown in FIGS. 5 and 6, the upper end portion and the lower end portion of the exterior portion may be respectively configured as the round shaft-like pivot shaft portion 12 and the magnets 13 may be provided on the respective pivot shaft portions 12 . The two rotation shafts 12 are both detachable from the bearing 21 of the stand 2. Thereby, even when the display device 1 does not have the automatic rotation function of the screen display, both the state in which the display device 1 is attached to the stand 2 of the driver's seat 3 and the state in which the display device 1 is attached to the stand 2 of the ceiling 4 In the state, the vertical direction of the screen can be made normal. Similarly, in the display device 1, the left end portion or the right end portion of the exterior portion may be the pivot shaft portion 12.

  Further, the number of magnets 13 provided on one rotation shaft 12 is not limited to one, and a plurality of magnets may be provided. For example, as shown in FIG. 7 or FIG. 8, two magnets 13 may be provided on one rotation shaft 12. At this time, as shown in FIG. 7, two stands 2 corresponding to two magnets 13 may be provided. As shown in FIG. 8, two magnets 22 respectively corresponding to two magnets 13 Provided with one stand 2 having the

  Moreover, the shape of the stand 2 is not limited to the shape illustrated in FIGS. 1 to 4. Any shape may be adopted as long as it has a concave bearing 21 fitted to the pivot shaft 12. For example, as shown in FIG. 9, the stand 2 provided on the back of the driver's seat 3 or the front passenger's seat may have a so-called “wedge surface” shaped bearing 21 formed by removing the corner of a substantially rectangular parallelepiped. good. Further, as shown in FIG. 10, the stand 2 provided on the ceiling 4 of the vehicle may be embedded in the ceiling 4 with a reduced thickness. Thus, the display system 100 may include a plurality of stands 2 having different shapes.

  In addition, the magnets 13 and 22 can hold the display device 1 in a state where the display device 1 is attached to the stand 2, and the magnetic force to such an extent that the display device 1 can be removed from the stand 2 with human hands. It does not have to be limited to ferrite magnets as long as it has For example, for a product in which a use environment in which vibration is severe is assumed in particular, the holding power of the display device 1 may be improved by using a rare earth magnet. Moreover, about the product in which the use environment which can ensure a power supply is assumed, it may replace with a permanent magnet and may use an electromagnet.

  Furthermore, when an electromagnet is used for the magnets 13 and 22, a sensor for detecting the approach, contact and detachment of the pivot shaft 12 is provided in the bearing 21 or the approach, contact and detachment of the bearing 21 is detected. A sensor may be provided on the pivot shaft portion 12 and a control unit may be provided to control the amount of current supplied to the magnets 13 and 22 in accordance with the detection results of these sensors. When the sensor does not detect any of the approach, the contact, and the detachment operation, the control unit stops the energization of the magnets 13 and 22. Thereby, the power consumption of the magnets 13 and 22 can be reduced. When the sensor detects an approach, the control unit causes the magnets 13 and 22 to apply a first current weaker than the reference current. Thereby, the user can attach it while finely adjusting the arrangement position of the display device 1 with respect to the stand 2. When the sensor detects contact, the control unit causes the magnets 13 and 22 to pass a second current stronger than the reference current. Thereby, the retention strength of display 1 can be secured. When the sensor detects the detachment operation, the control unit causes the first current to flow again to the magnets 13 and 22. Thereby, the user can easily remove the display device 1 without applying an excessive force.

  Moreover, although the example which provided the magnet 13 in the display apparatus 1 was shown in FIGS. 1-4, the magnet 13 may be exposed to the display apparatus 1 exterior.

It may be integrally formed with the like. By forming the stand 2 integrally with the vehicle, it is possible to unify the design and improve the aesthetic appearance.

  Further, the outer shape of the display device 1 is not limited to the rectangular plate shape, and the arrangement position of the pivot shaft 12 is not limited to the end corresponding to each side of the rectangle. For example, as shown in FIG. 11, the lower end portion of the display device 1 may be bent to the back side. Alternatively, as shown in FIG. 12, a convex portion may be formed on the back surface of the display device 1, and a tip end portion of the convex portion may be formed into a round surface and the pivot shaft portion 12 may be formed. Alternatively, two arms may be formed at the end or the back of the display device 1, and the rod-like pivot shaft 12 may be provided between the arms.

  The display device 1 may perform the function of the display device 1 in a state of being attached to the stand 2 and may perform the function of the display device 1 in a state of being removed from the stand 2. Thus, even if the display device 1 is attached to any one of the plurality of stands 2, the passenger holds the display device 1 in a situation where it becomes difficult for the passenger of the vehicle to look at the display unit 11. Thus, the video of the display unit 11 can be viewed. In addition, when the touch panel is provided integrally with the display unit 11 and the display device 1 has a system configuration that also functions as the operation input device, the operation of the touch panel can be made easier by removing the display device 1 from the stand 2 it can.
