Description

  The present invention relates to a portable electronic device including a display unit and a lid that protects the display unit.

  In portable electronic devices such as a portable electronic dictionary and a portable electronic notebook, a display unit such as an LCD (Liquid Crystal Display) is mounted. While portable electronic devices can be reduced in size and weight for the purpose of further improving portability, there is a great need for an increase in the size of a display portion. Therefore, conventionally, for the purpose of protecting the display unit of a portable electronic device, the portable electronic device has a protective cover that covers the display unit when the portable electronic device is not used and can be removed from the display unit when used. There are devices (for example, Patent Document 1).

  Such a protective cover for a portable electronic device is usually made of a thin plate-like member having a substantially uniform thickness, and is attached to the portable electronic device through a connecting portion such as a hinge so as to be opened and closed.

In addition, along with the downsizing of portable electronic devices, there are very many devices in which input means such as a touch panel is arranged on the display unit.

  Although the portable electronic device disclosed in Patent Document 1 can prevent unnecessary contact with the surface of the display unit by closing the protective cover, the portable electronic device itself falls or the display unit surface of the object It is not configured to protect the display unit against an impact such as a collision with the display. That is, since the plate thickness is thin due to the pursuit of portability, the structure is weak against a severe impact on the display unit surface.

  Further, even if the display unit is not damaged, the input means arranged in the display unit is likely to malfunction due to the bending of the protective cover due to an impact or the like.

  Although it is possible to increase the thickness of the protective cover in order to improve impact resistance, this is not preferable because it leads to an increase in the thickness of the portable electronic device itself and impairs portability.

  Although it is possible to use a material with high strength for the protective cover, such a material is usually very expensive and has difficulty in forming into the shape of the protective cover. Therefore, it is not suitable for use in portable electronic devices that are required to be provided at low cost.

  In the portable electronic device disclosed in Patent Document 1, when an impact is applied to the protective cover from a horizontal direction while the protective cover is closed, the protective cover is shifted in that direction. For this reason, the protective cover is opened and the display unit is exposed, and the load due to the shift is applied to the connection unit that connects the protective cover and the portable electronic device, so that the connection unit is easily damaged. Yes.

  The present invention has been made in view of the above-described problems, and provides a portable electronic device having improved impact resistance in various directions on the surface of a display portion without impairing portability.

  In addition, the present invention provides a portable electronic device in which an input unit disposed on a display unit does not malfunction even when an impact is applied to the display unit surface from various directions.

  In order to solve the above-described problems, the present invention provides a portable type having a case having an opening, a display unit disposed in the case so as to be viewable from the outside through the opening, and a lid that covers and protects the opening. The electronic device is characterized in that the lid portion has a protruding portion that protrudes in a substantially convex shape toward the inside of the opening portion at a portion corresponding to the opening portion when arranged so as to cover the opening portion. A portable electronic device shall be proposed.

  Thereby, since the thickness of the cover part of the part corresponding to the display part of a portable electronic device becomes thick, impact resistance improves.

  The lid portion of the present invention is characterized in that the outer surface when arranged so as to cover the opening portion is formed in a substantially flat shape.

  Thereby, the thickness as a portable electronic device can be maintained as usual while improving the impact resistance of the display unit by the protruding portion of the lid.

  Further, the side surface of the protruding portion of the lid portion of the present invention is characterized in that it is close to the inner side surface of the opening portion when the lid portion is arranged so as to cover the opening portion.

  As a result, even if an impact is applied from the horizontal direction to the lid surface of the portable electronic device, the lid portion is positioned and fixed by the proximity relationship between the protruding portion side surface and the opening side surface of the lid portion. , It is possible to prevent the lid from shifting.

  Further, the separation distance between the lid portion and the display portion of the present invention is set to a value larger than the amount of distortion in which the lid portion is distorted when a predetermined external pressure is applied perpendicularly to the lid portion.

  Thereby, even if an external pressure is applied perpendicularly to the lid, it is possible to prevent the lid from contacting the display unit.

  In addition to the above, the present invention also provides a portable electronic device having a case having an opening, a display unit arranged in the case so as to be viewable from the outside through the opening, and a lid that covers and protects the opening. A portable electronic device characterized in that the lid has a rib protruding toward the inside of the opening at a portion corresponding to the edge of the opening when the cover is arranged so as to cover the opening. Equipment shall be provided.

  Further, at this time, the lid has a rib over the entire circumference of the portion corresponding to the edge of the opening when it is arranged so as to cover the opening.

  Furthermore, the rib of the lid portion is characterized in that when the lid portion is distorted by applying a predetermined external pressure perpendicularly to the lid portion, the lid portion is in contact with a display portion located in the vicinity of the edge portion of the opening portion.

  As a result, even if external pressure is applied from a direction perpendicular to the lid, the lid is difficult to come into contact with the display, and the external pressure is dispersed by the ribs, so the display does not increase in thickness. It is possible to improve the impact resistance.

  Further, the outer side surface of the rib of the lid portion of the present invention is characterized in that it is close to the inner side surface of the opening portion when the lid portion is arranged so as to cover the opening portion.

  Thereby, even if an impact is applied from the horizontal direction to the lid surface of the portable electronic device, the lid portion is positioned and fixed by the proximity relationship between the outer side surface of the rib of the lid portion and the side surface of the opening portion. Therefore, it can prevent that a cover part slip | deviates.

  Moreover, the display part used with these portable electronic devices of the present invention described above may have an input means on its surface, and the lid part may be formed of a transparent elastic member.

  Furthermore, the present invention is not limited to a portable electronic device, but a main body having an opening, a display unit disposed in the main body so as to be viewable from the outside through the opening, and a lid that covers and protects the opening. The lid has a protruding portion that protrudes in a substantially convex shape toward the inside of the opening at a portion corresponding to the opening when the cover is arranged so as to cover the opening. An electronic device shall be provided.

  Further, the electronic device includes a main body having an opening, a display unit arranged in the main body so as to be viewable from the outside through the opening, and a lid that covers and protects the opening. Provided is an electronic device characterized by having a rib protruding toward the inside of the opening at a portion corresponding to the edge of the opening when arranged so as to cover the portion.

  According to the present invention, the strength of the portion of the lid corresponding to the opening of the case with respect to impact such as external pressure is increased, and as a result, the impact resistance of the display portion protected by the lid is improved.

  Moreover, since the cover part is provided with protrusions and ribs only in the direction toward the inside of the opening part corresponding to the opening part of the case, the thickness of the portable electronic device can be maintained as usual.

  Furthermore, when the lid is arranged so as to cover the opening of the case, the protruding part and rib of the lid are arranged so that the outer side surface is close to the inner side surface of the opening. Even if an impact is applied from a horizontal direction, the lid portion is positioned and fixed, and the lid portion is not displaced.

  Further, due to the distance between the lid and the display unit and the contact relationship between the rib and the display unit, even if an impact is applied perpendicularly to the lid and the lid is distorted, the lid does not contact the display. For this reason, even if it is a display part which has an input means, since a cover part does not contact an input means, it does not malfunction.

  A first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a top view of the portable electronic device of the present invention when the lid is opened. 1 is a portable electronic device according to the present invention, 2 is a case, 3 is an opening provided in the case, 4 is a display unit, 6 is a lid unit, 5 is a connection unit that connects the case 2 and the lid unit 6, Protruding portions 8 a to 8 f formed on the lid portion 6 are key input portions for operating the portable electronic device 1.

  As the display means of the display unit 4, for example, a flat panel such as an LCD is used. As will be described with reference to FIG. 2, screen input means such as a touch panel is provided on the surface of the display means of the display unit 4.

  The connection part 5 is a member that connects the lid part 6 to the case 2 so as to be openable and closable, and has, for example, a hinge structure.

  The lid 6 and the protrusion 7 will be described in detail with reference to FIG. 2, and the protrusion 7 has a shape in which the side surface is close to the inner side surface of the opening 3 and fits in the opening 3.

  FIG. 2 is a cross-sectional view of the portable electronic device 1 of the present invention when the lid 6 is closed.

  2a is an upper case forming the case 2, and 2b is a lower case. An opening 3 is disposed in the upper case 2a.

  3 a is an edge of the opening 3, and 3 b is an inner side surface of the opening 3.

  The display unit 4 is arranged so as to be in close contact with the edge 3a of the opening 3 of the upper case 2a and to be viewed from the outside of the portable electronic device 1. The display unit 4 is configured by arranging a flat panel display 4a such as an LCD and a surface input means 4b such as a touch panel on the top thereof.

  Reference numeral 6a denotes an outer surface of the lid portion 6, which is formed in a substantially flat shape and is not particularly raised.

  7 a is a projecting surface of the projecting portion 7 and faces the display portion 4 with a certain separation distance 10. Reference numeral 7 b denotes a side surface of the protruding portion 7, which is close to the inner side surface 3 b of the opening 3.

  The separation distance 10 is, for example, measured from the center portion of the lid portion 6 when a predetermined impact is applied in a direction perpendicular to the lid portion 6, and the strain amount that the lid portion 6 is distorted is measured, and is larger than the strain amount. Set to value.

  As can be seen from FIG. 2, the lid 6 is in contact with the upper case 2 a, and a portion corresponding to the opening 3, that is, the protruding portion 7 protrudes toward the inside of the opening. However, the outer surface 6a of the lid 6 is substantially flat and does not particularly protrude. By having such a structure, the lid 6 increases in strength against an impact applied in a direction perpendicular to the lid 6 and can protect the display unit 4 disposed in the opening 3 from the impact. It becomes. Furthermore, since the thickness as the portable electronic device 1 does not increase, the formability is not impaired.

  Further, since the side surface 7b of the protruding portion 7 is close to the inner side surface 3b of the opening 3, when an impact is applied to the lid portion 6 in the horizontal direction, the adjacent portions (ie, 7b and 3b) Contact each other and serve as a stopper against the horizontal displacement of the lid 6. Such a structure of the protrusion 7 prevents the lid 6 from being displaced, and as a result, it is possible to provide the portable electronic device 1 that is resistant to impact from the horizontal direction.

  Further, since the separation distance 10 is set in consideration of the distortion amount of the lid portion 6, even if the lid portion 6 is distorted inwardly of the opening due to an impact, it does not come into contact with the display portion 4, and an LCD or the like The flat panel display 4a is not damaged. Further, since the lid 6 (projecting surface 7a) is not in contact, malfunction of the surface input means 4b such as a touch panel cannot occur.

  Next, an example according to another portable electronic device of the present invention will be described with reference to FIG. The portable electronic device described in the second embodiment is a device having a rib on the lid portion 6.

  In addition, since the component as a portable electronic device is equivalent to the component demonstrated in FIG. 1 and FIG. 2 of Example 1, and has the same structure except the component which concerns on a protrusion part or a rib, it refuses especially. Unless otherwise indicated, the same reference numerals and the like are used, and a detailed description is omitted.

  FIG. 3 is a cross-sectional view of the portable electronic device 1 according to the second embodiment when the lid 6 is closed.

  Reference numeral 9 denotes a rib disposed on the lid 6 and is formed so as to be fitted inside the opening 3. Here, the ribs 9 are arranged over the entire circumference of the edge 3a of the opening 3. However, if the arrangement position is arranged so as not to infringe the display screen of the display unit 4, the entire circumference is obtained. There is no need to span.

  The rib 9 is separated from the display unit 4 with a certain separation distance 11. For example, when a predetermined impact is applied in a direction perpendicular to the cover unit 6 from the central portion of the cover unit 6, the display unit 4 is provided. It is arranged to come into contact with.

  In addition, the outer side surface 9 a of the rib 9 is arranged close to the inner side surface 3 b of the opening 3.

  As can be seen from FIG. 3, the lid 6 is in contact with the upper case 2 a, and the ribs 9 that are present on the entire periphery of the edge 3 a of the opening 3 protrude toward the inside of the opening 3. However, the outer surface 6a of the lid 6 is substantially flat and does not particularly protrude. Since the lid 6 has such a structure, even if an impact is applied in a direction perpendicular to the lid 6, the rib 9 comes into contact with the vicinity of the edge 3 a of the opening 3 of the display unit 4 to release the impact. Therefore, it is possible to prevent an impact from being directly transmitted to the display screen of the display unit 4 and to prevent the display unit 4 from being damaged. Furthermore, since the thickness as the portable electronic device 1 does not increase, the formability is not impaired.

  Further, since the side surface 9a of the rib 9 is close to the inner side surface 3b of the opening 3, when a shock is applied to the lid 6 in the horizontal direction, the adjacent portions (that is, 9a and 3b) are adjacent to each other. It contacts and plays the role of a stopper against the displacement of the lid 6 in the horizontal direction. Such a structure of the rib 9 prevents the lid 6 from being displaced, and as a result, it is possible to provide the portable electronic device 1 that is resistant to impact from the horizontal direction.

  In addition, since the rib 9 comes into contact with the display unit 4 and external impact is released to the surroundings, the lid unit 6 is less likely to be distorted in the inner direction of the opening 3 with respect to the impact applied in the direction perpendicular to the lid unit 6. As a result, the possibility that the lid 6 contacts the display unit 4 is greatly reduced. As a result, the flat panel display 4a such as an LCD is not damaged, and the lid portion 6 does not come into contact, so that a malfunction of the surface input means 4b such as a touch panel cannot occur.

  In addition, as a member of the lid part 6 used in the first and second embodiments, it is possible to use an elastic member having transparency such as polycarbonate, thereby improving the strength of the lid part 6 (resistance of the display part 4). In addition to (impact improvement), it is also possible to achieve an improvement in convenience that the display unit 4 can be viewed with the lid 6 closed.

  Moreover, although the said Example 1 and 2 is an example using a portable electronic device, for the purpose of improving the impact resistance of display parts, such as a stationary electronic device which has a display part, this invention and It is also possible to arrange a similar configuration or structure in an electronic device.
