Description

  The present invention relates to an electronic device with a rotating portion, and more particularly, to an electronic device with a rotating portion that can improve the problem of intrusion of moisture and the like into the electronic device from the gap between the rotating portions.

  There are many electronic devices with rotating parts. Examples of hand-held devices include mobile phones, cameras, and personal digital assistants (PDAs). FIG. 4 shows a conventional electronic device-PDA with a rotating part. This conventional electronic device 1 with a rotating part comprises a hollow main body part 11 and a hollow rotating part 12 as a photographing means attached to the main body part 11 by means of pivot means (not shown). It is a thing.

  Of course, electronic equipment is also built in the hollow inside of the rotating part 12 as the photographing means, but the electronic equipment is connected to the electronic equipment built in the hollow inside of the main body 11 by wiring (not shown). Since the wiring must be controlled, the wiring is routed through a through hole (not shown) that is arranged in the pivot means and communicates with the hollow interiors of the main body 11 and the rotating part 12. Furthermore, the pivoting means has two relative pivotable / rotatable structures with a gap between them.

  For this reason, the hollow interior of each of the main body 11 and the rotating part 12 is more or less in communication with the atmosphere through the through holes and the gaps, and intrusion of moisture or the like becomes a problem.

  Accordingly, an object of the present invention is to provide an electronic device with a rotating part that can solve the problem of intrusion such as moisture by the pivot means.

  In order to achieve the above-mentioned object, the present invention has a hollow rotating part in which a first set of electronic equipment is housed therein, and a second set of electronic equipment is incorporated therein so that it can be turned by means of a pivot. A first concavo-convex structure connected to the hollow main body, and the pivot means being fitted so as to be rotatable at least with respect to each other, and one of the first concavo-convex structures. Are formed on the main body, and the first set of electronic equipment and the second set of electronic equipment are convex in a substantially axial direction of the first concavo-convex structure. In the electronic device with a rotating portion that is electrically coupled by wiring through the structure, at least one of both ends of the gap between the concave structure and the convex structure in the first uneven structure is sealed with a seal. Electronic with rotating part, characterized by being stopped To provide a vessel.

  In the electronic device with a rotating part of the present invention having the above-described configuration, the gap between the concave structure and the convex structure in the concavo-convex structure is sealed with a seal, so that the penetration of moisture and the like into the electronic device is prevented. Airtightness inside the device can be maintained and the reliability of the electronic device can be improved.

  1 to 3 show a personal digital assistant (hereinafter referred to as PDA) cited as an embodiment of the electronic device with a rotating unit of the present invention. FIG. 1 is a perspective view thereof, FIG. 2 is an exploded view thereof, and FIG. 3 is a cross-sectional view of an essential part thereof.

  First, referring to FIG. 1, the PDA is provided with a camera unit (photographing means) 3. The camera unit 3 has a cylindrical shape and is pivotally supported by the main body unit 2.

  2 and 3, the main body 2 and the camera 3 are each hollow and incorporate electronic equipment. Concave portions 22 are formed in the front peripheral edge 23 of the main body 2, and cylindrical concave structures 24 and 25 are formed on both end surfaces of the concave portion 22, respectively. One of the two end faces with the concave structure 24 is a hollow shape of the main body portion 2, and the other of the two end surfaces is a solid shape with the hollow shape of the main body portion 2. In addition, the concave structure 24 does not have a bottom surface, and the back side thereof is an opening that communicates with the internal space of the main body 2. The concave structure 25 has a bottom surface and does not communicate with the internal space of the main body 2 at all.

  The cylindrical camera portion 3 has convex structures 311 and 312 corresponding to the concave structures 24 and 25 on both end surfaces thereof. The convex structure 311 is inserted and fitted into the concave structure 24 from the outside, and the convex structure 312 is also inserted and fitted into the concave structure 25 from the outside. These fittings allow the camera unit 3 to rotate with respect to the main body unit 2. Referring to FIG. 2, a rubber annular seal 41 is provided on the outer peripheral surface of the convex structure 311 formed in a columnar shape. Further, when looking at FIG. 3, the annular seal 41 is located outside the outer opening of the concave structure 24 on the convex structure 311, and on the peripheral edge of the outer opening of the concave structure 24 and both end faces of the camera unit 3. It is sandwiched. The fixing sheet 33 is attached to the distal end surface of the convex structure 311 by a fixing screw 34 so that the peripheral edge thereof is in contact with the peripheral edge outside the opening on the back side of the concave structure 24. Furthermore, the wiring 32 is incorporated in each of the main body 2 and the camera unit 3 via the through hole 35 penetrating the convex structure 311 and the fixing sheet 33 along the axial direction X of the concave structure 24 and the convex structure 311. The electronic equipment is electrically connected. Further, the convex structure 312 has a cylindrical shape with a bottom surface. As a biasing means in the cylinder, the bottom surface in the cylinder of the cylindrical convex structure 312 and the bottom surface of the concave structure 25 are formed at both ends by the biasing force. A coil spring 42 to be pressed is attached.

Next, advantages of the PDA with a camera unit due to the structure will be described.
As illustrated, the gap between the outer peripheral edge of the concave structure 24 and the camera unit 3 is sealed by an annular seal 41 installed on the outer peripheral surface of the convex structure 311. Further, the coil spring 42 attached in the convex structure 312 on the opposite side of the convex structure 311 presses the camera unit 3 and the bottom surface of the concave structure 25 at both ends. By pressing the coil spring 42, the camera unit 3 has obtained a force to move to the left, so that the seal 41 is pressed against the outer peripheral edge of the concave structure 24. With this configuration, since both end surfaces of the seal 41 sandwiched between the outer peripheral edge of the concave structure 24 and the camera unit 3 are tightly sealed, the body unit 2 such as moisture and the camera unit 3 It is possible to prevent the intrusion into the electronic device from the gap existing by the coupling.

  In addition, due to the long-term use of the PDA, the thickness of the seal 41 gradually decreases due to friction. However, since the coil spring 42 on the opposite side always pushes the camera unit 3 to the left, the seal 41 is completely removed due to friction. Until both ends of the seal 41, the both ends of the seal 41 are kept sealed, so that the service life can be extended.

  In the electronic device with a rotating part (PDA) of the present invention configured as described above, the gap between the concave structure 34 and the convex structure 311 in the concavo-convex structures 24 and 311 is sealed with the seal 41, so that the moisture inside the electronic apparatus This is quite useful because it can prevent the intrusion of the electronic device, that is, keep the airtightness inside the electronic device, increase the reliability of the electronic device, and extend the service life of the electronic device.

The perspective view of electronic device-PDA with a camera part which can rotate. FIG. 2 is an exploded configuration diagram of the PDA shown in FIG. 1. It is principal part sectional drawing of PDA shown in FIG. It is the conventional electronic device-PDA with a rotation part.
