  ADVANTAGE OF THE INVENTION According to this invention, the electronic device which can prevent damage to a display apparatus by weakening the impact transmitted to a display apparatus can be provided.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an appearance of an electronic apparatus according to the present embodiment. The electronic device 1 includes a main body 2, and a display housing 3 is rotatably attached to the main body 2 via a hinge portion 4. A display device 5 such as an LCD (Liquid Crystal Display) is incorporated in the display housing 3, and the display device 5 is covered with an upper housing (mask housing) 6 and a lower housing (cover housing) 7.

  A touch pad 8 and a keyboard 9 are attached to the upper surface 2 a of the main body 2. The main body 2 has an upper case 10 and a lower case 11 made of resin or a metal such as magnesium alloy, and a circuit board (not shown) on which a plurality of electronic components are mounted is accommodated in the main body 2.

  FIG. 2 is an exploded perspective view of the display device of the electronic apparatus according to the present embodiment. The display device 5 is incorporated in the display housing 3 so as to be sandwiched between the upper housing 6 and the lower housing 7. The display device 5 is provided with an inverter circuit 20. The inverter circuit 20 supplies power to a backlight (not shown) arranged in parallel with the display device 5.

  The display device 5 is screwed to the fixing member 21 and is screwed to the lower housing 7 through a screw hole provided in the fixing member 21. After the display device 21 is screwed to the lower housing 7 using the fixing member 21, the upper housing 6 is covered, and the display device 3 including the upper housing 6 and the lower housing 7 is attached to the display device 3. 5 is accommodated.

  When external vibration or impact is applied to the display device 5 attached to the fixing member 21 such as a sheet metal by screw fixing or the like, the display device 5 moves due to elastic deformation or plastic deformation of the fixing member 21, Surrounding structures such as the housing 6 and the lower housing 7 may come into strong contact with each other, and the display device 5 made of glass or the like may be damaged.

  In the electronic apparatus 1 according to the present embodiment, the beam 30 is provided on the inner surface 7 a of the lower housing 7. As shown in the plan view of FIG. 3, the beam 30 does not contact the display device 5 when the display device 5 is incorporated. The beam 30 is provided at a position where the corner portion 40 of the display device 5 and the surface 30a of the beam 30 are in contact with each other when vibration or impact is applied to the display device 5 due to, for example, the electronic device 1 being dropped.

  Since the corner portion 40 of the display device 5 is higher in rigidity than other parts of the display device 5, the corner portion 40 of the display device 5 first contacts the beam 30 when an impact such as dropping is applied. The impact applied to the display device 5 can be reduced.

  FIG. 3 is an enlarged view showing a beam portion provided on the inner surface of the casing of the electronic apparatus according to the present embodiment. As shown in the enlarged view of FIG. 3, the distance a between the corner portion 40 of the display device 5 and the beam 30 and the distance b between the side portion 50 of the display device 5 and the beam are smaller than the distance b. The beam 30 is provided so that the corner portion 40 contacts the beam 30 before the side portion 50 when the display device 5 moves due to vibration or impact applied to the display device 5. . Even if the display device 5 comes into contact with the beam 30, the first contact portion becomes the corner portion 40 of the display device 5 having high rigidity, and damage to the display device 5 can be prevented.

  By providing the beam 30 in the lower housing 7, for example, when an impact is applied to the display device 5 due to the drop of the electronic device 1, the impact is reduced and the display device 5 can be made difficult to break.

  The beams 30 can be provided corresponding to the four corners 40 of the display device 5 respectively. However, for example, only two beams 30 may be provided corresponding to the two corners 40 on one side 50. The angle between the side portion 50 and the beam 30 of the display device 5 may be an angle other than that shown in FIGS.

  FIG. 4 is an enlarged view showing a beam portion of the display device according to the second embodiment. In the second embodiment, a beam having a different shape from that shown in the first embodiment is used. In addition to the beams shown in FIGS. 2 and 3, a beam having a curved surface 60a such as a beam 60 shown in FIG. 4 may be adopted. When an impact is applied to the display device 5, the curved surface 60 a may be brought into contact with the corner of the display device 5. If the surface where the beam 60 and the corner portion 40 of the display device 5 are in contact with each other is a curved surface 60a, the stress is diffused on the curved surface 60a when the beam 60 and the corner portion 40 of the display device 5 are in contact with each other. It can be set as a structure and destruction of the display apparatus 5 can be prevented.

  FIG. 5 is an enlarged view showing a beam portion of a display device according to another embodiment. In the third embodiment, beams having different shapes from those shown in the first and second embodiments are used. As in the beam 70 shown in FIG. 5, the beam 70 may be provided with a cushioning material 71 on the front surface 70 a of the beam 70. The beam 70 and the buffer material 71 are bonded using an adhesive or the like. When an impact is applied to the display device 5 such as when the main body 2 is dropped, the cushioning material 71 comes into contact with the corner portion 40 and can absorb the impact caused by the fall. By providing the cushioning material 71 on the front surface 70a of the beam 70, the impact applied to the display device 5 can be reduced as compared with the case where only the beam is provided on the inner surface 7a of the lower housing 7.

  As described above, according to the embodiment of the present invention, it is possible to provide an electronic apparatus capable of preventing the display device from being damaged by weakening the impact transmitted to the display device.
