Description

  The present invention relates to an electronic device having a display panel.

  As electronic devices such as digital cameras are made thinner, display panels such as LCDs are also made thinner and weak against external forces. In particular, thin electronic devices are often carried in clothes pockets, and a large external force may be applied by the movement of the user.

For this reason, Patent Document 1 discloses a method of increasing the rigidity around the display panel by attaching a reinforcing member as a separate member to a frame that holds the display panel in the electronic device.
JP 2003-316275 A (paragraphs 0018 to 0019, FIG. 1, etc.)

  However, the method of attaching a reinforcing member, which is a separate member, to the frame as in Patent Document 1 causes an increase in weight due to an increase in parts and an increase in manufacturing cost.

  The present invention provides an electronic apparatus in which the rigidity around the display panel can be increased without adding a reinforcing member as a separate member.

An electronic apparatus according to an aspect of the present invention includes a display panel, a first frame that is a member for holding the display panel and has a base portion disposed on the back side of the display panel, and the display panel. And a second frame disposed on the display surface side of the display panel. The first frame, the support portion extending from the base portion to the second frame side. Then, the support portion is bend over four positions including vertical folded portion of the base portion is formed, a vertical folded portion of the 4 or more points of the bending portion when the second frame is subjected to an external force The second frame is supported by a portion between the two bent portions except the two.

An electronic apparatus according to another aspect of the present invention includes a display panel, a first frame having a base portion that is a member for holding the display panel and is disposed on the back side of the display panel, A member for holding the display panel, at least a portion of which is a second frame disposed on the display surface side of the display panel. The first frame, the support portion extending from the base portion to the second frame side. The support portion includes a first portion bent toward the second frame with respect to the base portion, a second portion bent toward the opposite side of the base portion with respect to the first portion, and A third portion bent toward the second frame side with respect to the second portion and a fourth portion bent toward the opposite side of the second frame side with respect to the third portion are formed. Has been . When the second frame receives an external force, the second frame is supported by the second portion.

  According to the present invention, the rigidity of the support portion formed by bending the first frame can be increased, and the second frame that has received an external force can be supported by the support portion. For this reason, the rigidity around the display panel can be increased without adding new parts such as a reinforcing member.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  First, FIG. 5 shows a digital camera as an electronic apparatus according to an embodiment of the present invention. A photographing lens 16 is attached to the front surface of the camera 30 as indicated by a dotted line in the figure. On the other hand, on the back side of the camera 30, the display surface of the display panel 3 such as an LCD can be observed through the transparent protective plate 7. On the display panel 3, an image captured by the camera 30 and a menu image for setting the function of the camera 30 are displayed. An operation member 15 for selecting an imaging mode and function of the camera 30 is disposed on the back surface of the camera 30.

  FIG. 1 shows a part of the cross section of the holding structure of the display panel 3 when the camera 30 shown in FIG. 5 is cut along the line BB. FIG. 2 shows an exploded configuration of the display panel side of the camera 30 including the holding structure.

  Reference numeral 6 denotes a chassis of the camera 30, and an imaging device such as a photographing lens 16, a CCD sensor, and a CMOS sensor, an electric circuit board, and the like are attached to the chassis 6. The chassis 6 is preferably formed of a highly rigid metal material, but may be formed of a resin material. In addition, the camera 30 of the present embodiment is provided with the chassis 6 as an independent component. However, the chassis 6 does not necessarily have to be provided, and the chassis 6 that supports the base portion 20 of the lower frame 1 is not necessarily provided. It suffices if an alternative structure is in the camera. Such a structure may be referred to as a “chassis”.

  Reference numeral 1 denotes a lower frame (first frame) formed of a metal material, and a base portion (rectangular plane portion) 20 is fixed to the chassis 6 with screws on the back side of the display panel 3. However, as a method of fixing the base portion 20 to the chassis 6, the base portion 20 may be fixed by pressing with an exterior member 8 described later.

  Reference numeral 5 denotes an optical sheet for allowing a backlight for illuminating the display panel 3 from the back side to uniformly enter the display panel 3. A spacer 4 made of resin is disposed outside the optical sheet 5 in the base portion 20 of the lower frame 1. The display panel 3 is placed on the end of the spacer 4 opposite to the base portion 20.

  Then, an upper frame (second frame) 2 formed of a metal material is covered from the display surface side of the display panel 3. The upper frame 2 includes a pressing portion 2a that abuts on the display surface of the display panel 3 (however, outside the region where an image is displayed) and leg portions 2b that extend from the outer periphery of the pressing portion 2a to the lower frame 1 side. . The upper frame 2 is fixed to the lower frame 1 or fixed to a spacer 4 fixed to the lower frame 1. The fixing method at this time may be any method including hooking or screw tightening with a pawl shape and pressing with an exterior member 8 described later.

  The upper frame 2 is covered with the exterior member 8. A protective plate 7 for protecting the display panel 3 described above is attached to the exterior member 8 with a double-sided tape 10. In addition, a cushion material 9 having a function of dispersing external force, which will be described later, and a function of preventing dust and dust from entering the display panel 3 is disposed between the upper frame 2 and the protective plate 7.

  Note that the protective plate 7 is not always necessary, and the exterior member 8 may only have an opening that allows the display surface of the display panel 3 to be observed. In this case, the cushion material 9 is disposed between the upper frame 2 and the exterior member 8 or between members other than the protective plate 7 attached to the exterior member 8.

  Next, the shape of the lower frame 1 will be described in detail. FIG. 3 is a perspective view showing the entire lower frame 1. The holes 1 i and 1 j formed in the base portion 20 are used for positioning the spacer 4. The position of the spacer 4 with respect to the lower frame 1 is determined by inserting the pin portion formed in the spacer 4 into the holes 1i and 1j. The hole 1k formed in the base portion 20 is a hole into which a boss portion provided in the chassis 6 is inserted, and the pin portion of the spacer 4 inserted into the hole 1i is further formed in the chassis 6. As a result, the lower frame 1 is positioned with respect to the chassis 6.

  In this embodiment, the lower frame 1 includes a rectangular base portion 20 and four support portions 21 to 24 formed by bending over a specific length region of the four sides of the base portion 20.

  FIG. 4 shows a cross section taken along line AA of one of the support portions 21 to 24 of the lower frame 1 shown in FIG. 3 (support portion 23 in the figure). All four support parts 21-24 have the same bending shape.

  Each support portion has four bent portions 1a to 1d including a standing bent portion 1a from the base portion 20 to the upper frame 2 side, and more specifically has the following shape.

  Each support portion includes a first portion 1ab bent 90 degrees toward the upper frame 2 by the standing bent portion 1a, and a bent portion 1b which is an end of the first portion 1ab on the upper frame 2 side, on the base portion 20 side. And a second portion 1bc bent 90 degrees on the opposite side (outside of the lower frame 1). In addition, each support portion has a third portion 1cd that is bent 90 degrees toward the upper frame at a third bent portion 1c that is an outer end of the second portion 1bc. Further, each support portion is a fourth portion bent 180 degrees to the opposite side (chassis side) from the upper frame 2 side at the fourth bent portion 1d which is the end of the third portion 1cd on the upper frame 2 side. 1de.

  In other words, when the lower frame 1 is viewed from the display panel side, the first bent portion 1a is 90 degrees valley-folded with respect to the base portion 20, and the second bent portion 1b is a mountain with respect to the first portion 1ab. Each fold is bent 90 degrees. Further, the third bent portion 1c is bent at 90 degrees by valley folding with respect to the second portion 1bc, and the fourth bent portion 1d is bent at 180 degrees by mountain folding with respect to the third portion 1cd.

  In addition, although the present Example has shown the case where the support part is formed in all the four sides of the lower frame 1, it is not necessary to form a support part in all the four sides.

  Next, the relationship between the lower frame 1 and other components will be described. The end surface of the leg portion 2b of the upper frame 2 is in contact with the second portion 1bc which is a portion between the second bent portion 1b and the third bent portion 1c formed on each support portion of the lower frame 1. It touches. Hereinafter, this contact portion is referred to as a first contact portion 11. In other words, of the four bent portions 1a to 1d in the support portion, the portion between the two bent portions 1b and 1c excluding the standing bent portion 1a from the base portion 20 constitutes the first contact portion 11. .

  In each support portion, an end face 1e of the fourth portion 1de extending from the fourth bent portion 1d to the side opposite to the upper frame 2 is in contact with the chassis 6. Hereinafter, this contact portion is referred to as a second contact portion 12.

  Furthermore, the fourth bent portion 1d, which is the end portion on the upper frame 2 side of the third and fourth portions 1cd and 1de in each support portion, protrudes beyond the upper frame 2 to the exterior member 8 side. A protective plate 7 that is a member attached to the exterior member 8 is in contact with the fourth bent portion 1d. Hereinafter, this contact portion is referred to as a third contact portion 13.

  The fourth bent portion 1d may be in direct contact with the exterior member 8 or in contact with a member other than the protective plate 7 attached to the exterior member 8.

  Next, dispersion of the external force when the external force P is applied to the exterior member 8 as shown in FIG. 1 will be described. 1 shows that the external force P acts on the exterior member 8 only from a direction perpendicular to the display surface of the display panel 3, but the actual external force acts from a direction other than the perpendicular direction. There is a case. Therefore, the external force P indicates the vertical component of the external force that actually acts on the exterior member 8.

  When an external force P is applied to the exterior member 8, first, transmission of the external force to the internal components of the camera 30 including the display panel 3 is suppressed by the rigidity of the exterior member 8 and the protection plate 7. When an external force P exceeding the rigidity is applied, the external force is transmitted to the support portions 21 to 24 of the lower frame 1 via the third contact portion 13 and the upper frame via the cushion material 9. 2 is dispersed in the external force component transmitted to 2. However, since the cushion material 9 is elastic, most external force components are transmitted to the support portions 21 to 24 of the lower frame 1 via the third contact portion 13.

  Here, since each support part has three 90 degree bending parts 1a, 1b, and 1c and one 180 degree bending part 1d as mentioned above, it has high rigidity. Further, the fourth portion 1de in each support portion is in contact with the chassis 6 at the second contact portion 12. In other words, each support portion that has received an external force is supported by the chassis 6 at the second contact portion 12. For this reason, as a rigidity of a support part, the rigidity by contact | abutting with the chassis 6 is added to the rigidity by providing the said 4 bending parts 1a-1d.

  As the rigidity of each support portion increases, the external force component transmitted to the upper frame 2 via the cushion material 9 decreases, and as a result, the external force component acting on the display panel 3 via the upper frame 2 also decreases.

  When a larger external force P is applied to the exterior member 8 and the external force component transmitted to the upper frame 2 via the cushion material 9 increases, the external force component transmitted to the upper frame 2 is transmitted to the lower frame via the first contact portion 11. 1 to each support part. In other words, the upper frame 2 receiving the external force is supported by the second portion 1bc in each support portion. As described above, each support portion has four bent portions 1a to 1d and has high rigidity, and since the fourth portion 1dc is in contact with the chassis 6 at the second contact portion 12, it is further rigid. Becomes higher. Therefore, even when a large external force P is applied, the external force component transmitted to the display panel 3 can be extremely reduced.

  In the above-described embodiment, the support portion of the lower frame 1 and the upper frame 2, the support portion and the chassis 6, and the support portion even when the external force P does not act on the first to third contact portions 11 to 13. The case where the exterior member (protection plate 7) is in contact has been described. However, when the external force P is not applied, the first to third contact portions 11 to 13 are provided with a slight gap to absorb the assembly error, and when the external force is applied, the first to third contact portions are applied. You may comprise so that the contact parts 11-13 may contact | abut. Moreover, in the said Example, in the 1st-3rd contact parts 11-13, the support part and upper frame 2 of a lower frame 1, a support part and a chassis 6, and a support part and an exterior member (protection board 7) are directly. The case of contact has been described. However, another member may be interposed between the members that contact at each contact portion.

  In short, in the first to third contact portions 11 to 13, when an external force P is applied, the upper frame 2 is supported by the support portion of the lower frame 1, the support portion is supported by the chassis 6, and the support portion As long as the exterior member (protective plate 7) is supported by the above-described structure.

  Moreover, although the said Example demonstrated the case where each support part was formed by the bending process in four places (4 times), the bending frequency and shape of a support part are not restricted to this, Four or more bending processes Therefore, it is only necessary to have a contact portion with the upper frame 2 such as the first contact portion 11.

  Furthermore, although the digital camera having a display panel has been described in the above embodiment, a display panel holding structure similar to that in the above embodiment may be adopted in an electronic apparatus other than the digital camera.
