Sectional drawing (opening-closing stopper 85 part) of the electronic device 100 which concerns on the Example of this invention.

  FIG. 1 is an external perspective view of an electronic device 100 according to an embodiment of the present invention. The electronic device 100 is an example of a foldable mobile phone, in which FIG. 1A shows a folded and closed state, and FIG. 1B shows an opened state.

  The electronic device 100 has a structure in which a first housing 70 and a second housing 80 are rotatably connected by a hinge 90. The 1st housing | casing 70 is a housing | casing which has a main display part (not shown) and an audio | voice receiver (not shown). The second housing 80 is a housing having operation keys (not shown) and a microphone (not shown).

  The hinge 90 includes a first hinge 91 and a second hinge 92 that are a rotational pair. The first housing 70 is attached to the first hinge 91, and the second housing 80 is attached to the second hinge 92. The first housing 70 and the second housing 80 rotate.

The first housing 70 includes an outer case 10 (a first case that is outside when closed) and an inner case 20 (a second case that is inside when closed). The outer case 10 has various designs and can be selected according to the user's preference. The outer case 10 is slidably attached to and detached from the inner case 20 in the illustrated sliding direction. This sliding direction is a direction parallel to the main surface of the first housing 70 and perpendicular to the rotation axis of the hinge 90.
The inner case 20 includes a main display unit (not shown) and an audio receiver (not shown).

  The second casing 80 has an opening / closing stopper 85 at the end on the hinge 90 side. When the first casing 70 and the second casing 80 are opened to the maximum, the outer case end 15 of the outer case 10 abuts against the opening / closing stopper 85 and stops, and the opening / closing angle becomes about 165 degrees.

  The opening / closing stopper 85 is made of an elastic material such as elastomer (R) so that the abutting outer case end 15 is not damaged.

Next, the sliding structure of the outer case 10 and the inner case 20 will be described.
FIG. 2 is an exploded perspective view of the first housing 70 of the electronic device 100 according to the embodiment of the present invention.
The first housing 70 includes an outer case 10, an inner case 20, a screw 30 for fastening both cases, and the like. The first hinge 91, which is one of the rotation pairs of the hinge 90, has a first hinge inner cover 911 and a first hinge outer cover 912 and is attached to the inner case 20. The first hinge 91 may be configured integrally with the inner case 20.

  The outer case 10 includes side fitting claws 11 (6 on the left and right side in total), fitting claws 12 (two on the end surface opposite to the hinge), fitting claws 13 (two on the hinge side), and screw receivers 14. (Two), an outer case end 15 (an end near the hinge), an outer case end 16 and the like. The inner case 20 includes side fitting claws 21 (total of six on the left and right side faces), fitting claws 22 (two on the end surface opposite to the hinge), and the like. The first hinge inner cover 911 is formed with screw holes 94 (two), and the first hinge outer cover 912 has fitting claws 93 (two).

  The opposing side fitting claws 11 and the side fitting claws 21, the fitting claws 12 and the fitting claws 22, and the fitting claws 13 and the fitting claws 93 are fitted in pairs.

  Next, a procedure for sliding the outer case 10 and the inner case 20 will be described. When mounting, first, the pair of claws are superposed in a state where they are shifted in the sliding direction so as not to overlap each other in a direction perpendicular to the main surface of the first housing 70 and the side surfaces of the cases are overlapped. Then, the outer case 10 is mounted by sliding in the direction of the first hinge 91 of the inner case 20.

  In this mounted state, the pair of claws are fitted to each other so that the outer case 10 and the inner case 20 cannot be pulled out in the direction perpendicular to the main surface, and no backlash occurs between the two cases. The pair of claws overlap each other and a drag is generated between the pair of claws.

  Therefore, when the above-described sliding attachment is performed, no drag force is generated in the first stage, but a drag force is generated in the latter half stage where the pair of claws are overlapped with each other, and some force is required for sliding. However, since the outer case end portion 16 of the outer case 10 is located outside the end portion of the inner case 20, the outer case end portion 16 can be easily slide-mounted by pushing the outer case end portion 16 toward the first hinge 91 with a finger. . When the slide mounting is finished, the screw 30 is then passed through the screw hole 94 and screwed into the screw receiver 14 to be fixed, and the mounting and fixing of the outer case 10 and the inner case 20 is completed.

  When removing the outer case 10 and the inner case 20, first, after removing the screw 30, the outer case 10 is slid and removed from the inner case 20, but at this time, a drag is generated by the fitting claw, The outer case 10 and the inner case 20 are difficult to remove because the ends overlap each other and there is no place to put a finger. This removal procedure will be described later (FIG. 4).

Next, the cross section of the screw 30 and the cross section of the fitting claw 13 as viewed in FIG.
3 is a cross-sectional view of the electronic device 100 according to the embodiment of the present invention. FIG. 3A is a cross-sectional view of the screw 30 as viewed in the direction of FIG. 2, and FIG. It is sectional drawing of the fitting nail | claw part 13 seen from the arrow. The opening / closing angle of the first housing 70 and the second housing 80 is about 165 degrees, and the state where the mounting and fixing of the outer case 10 and the inner case 20 is completed is illustrated.

  In FIG. 3A, the outer case 10 and the inner case 10 of the first housing 70 are fixed by screwing the screw 30 through the screw hole 94 and screwing into the screw receiver 14. One second hinge 92 of the rotating pair of hinges 90 is fixed to the end of the second housing 80.

  In FIG. 3B, when the fitting claw 13 of the outer case 10 of the first housing 70 is slid and attached, it rides on the fitting claw 93 provided on the cover portion of the hinge 91, The fitting claw 13 and the fitting claw 93 are engaged with each other by being pushed into the back. Therefore, even when the screw 30 is removed, at the stage where the outer case 10 and the inner case 10 are slid and removed, the fitting between the fitting claw 13 and the fitting claw 93 and the side fitting described in FIG. A drag force is generated by the fitting of the mating claw 11 and the side fitting claw 21 and the fitting claw 12 and the fitting claw 22, so that it is difficult to remove.

Next, the slide removal procedure for the outer case 10 and the inner case 20 will be described.
FIG. 4 is a cross-sectional view of the electronic device 100 according to the embodiment of the present invention, and is a cross-section of the opening / closing stopper 85 portion as viewed in FIG. 4A shows a state where the opening and closing angles of the first housing 70 and the second housing 80 are 165 degrees, and FIG. 4B shows a state where the screws 30 are removed and the opening and closing angles are further expanded to 180 degrees. Show.

  FIG. 4A shows a state in which the first case 70 and the second case 80 are opened in a state in which the outer case 10 and the inner case 20 are screwed with the screws 30, and the opening / closing angle is about 165 degrees. In other words, the outer case end 15 of the outer case 10 of the first housing 70 is in contact with the opening / closing stopper 85 of the second housing 80. Since the outer case 10 is firmly screwed to the inner case 20 in the vicinity of the outer case end 15 with the screw 30, the outer case end 15 is fixed by the screw 30 even when the outer case end 15 is pushed by the opening / closing stopper 85. The inner case 20 also does not move and does not open beyond 165 degrees.

  Next, the slide removal procedure of the outer case 10 and the inner case 20 will be described in detail. First, the screw 30 is removed so that the outer case 10 and the inner case 20 are free. However, even in this state, since there is a drag by the fitting claws, it is difficult to directly grip and slide the outer case 10 by hand.

  In the present invention, when the first casing 70 and the second casing 80 are opened by hand and the opening / closing angle is about 165 degrees, as shown in FIG. The outer case end 15 of the outer case 10 abuts against the opening / closing stopper 85 of the second housing 80.

  However, since the screw 30 is removed, the opening / closing angle is further widened, that is, when the inner case 20 fixed to the first hinge 91 is pushed by hand in a direction in which the opening / closing angle extends to 165 degrees or more, 15 is pushed by the opening / closing stopper 85 to receive a pressing force in the slide removal direction. This pressing force generates a force larger than the drag force generated by the fitting claw between the inner case 20 and the outer case 10, and the outer case 10 slides relative to the inner case 20 and moves in the removing direction. As shown in B), the outer case 10 slides with respect to the inner case 20 in a state where the opening / closing angle is 180 degrees.

  Thus, in the state opened to the opening and closing angle of 180 degrees, the fitting by the fitting claw is almost disengaged and there is no dragging force. After that, even if the outer case 10 is directly gripped by hand, it can be easily removed. Can do. Moreover, since the outer case end 16 on the opposite side of the hinge of the outer case 10 is also displaced from the end of the inner case 20, a finger can be put on this part and can be easily removed.

  As described above, according to the embodiment of the present invention, a dedicated jig for removing a fitted case in an electronic device having a structure in which the case is slidably fitted to the surface of the housing. The case can be easily removed without the need to provide a part, without damaging the case, and without providing a part for hooking the finger on the case.

  Note that the electronic device of the present invention can be applied to a mobile phone, a PHS, and other devices having a folding structure.
