Description

  The present invention relates to a hinge module and an electronic device.

  2. Description of the Related Art Conventionally, in an electronic device, for example, a mobile phone, a configuration in which a first case having a display unit and a second case having a key input unit are rotatably connected by a hinge unit has been put into practical use. Such a mobile phone, for example, rotates the first and second cases around the hinge portion and carries them in a superimposed manner, and rotates and deploys the first and second cases, It is configured to be used in an open form.

  Such an electronic device is desirably waterproof in order to cope with its use environment, and the hinge structure that connects the first case and the second case is also required to be waterproof.

  The following structure is known as a hinge structure having waterproofness. For example, a hinge portion that rotatably connects a first case and a second case, and an electronic circuit in the first case and an electronic circuit in the second case are electrically connected through the inside of the hinge portion. The connection wiring to be connected to each other and the inside of the hinge portion, the connection wiring is inserted into the inside, and in this state, one end is opened to the inside of the mounting hole of the first case and fixed tightly. In addition, there is known a hinge structure including a waterproof tube whose other end is opened and fixed inside the mounting hole of the second case (see Patent Document 1).

  In such a hinge structure, when the connection wiring is inserted into the hinge portion that rotatably connects the first case and the second case, one end of the waterproof tube into which the connection wiring is inserted is the first end. It is fixed in close contact with the mounting hole of the case. Further, the other end of the waterproof tube is closely fixed to the mounting hole of the second case. Thereby, even if water intrudes into the hinge portion, the waterproof tube prevents water from entering into the first and second cases, thereby ensuring waterproofness.

In the conventional hinge structure, the waterproof tube mounting hole provided in the first case and the waterproof tube mounting hole provided in the second case are arranged in the width direction of the first case and the second case. It is provided by shifting to For this reason, for example, if an attempt is made to set a rotation axis that rotates the first case relative to the second case, a rotation radius corresponding to the distance of shifting the mounting hole is set at the minimum. It is disadvantageous for conversion.
For these reasons, the conventional hinge structure is applied to electronic devices that perform operations other than the rotational operation in which the first case and the second case are rotated to overlap each other or unfolded to be opened to each other. It was difficult to apply.

  This invention is made | formed in view of the said problem, The objective is to provide the hinge module which can implement | achieve several rotation operation | movement, ensuring waterproofness.

  In order to solve the above-described problem, a hinge module disclosed in the present specification is mounted on an electronic device having a first case and a second case, and the first bracket and the first bracket mounted on the first case are provided.

Features.

  By using such a hinge module, a plurality of rotational operations are realized while ensuring waterproofness.

  That is, it is possible to prevent the cable from being exposed to moisture by housing the cable in the waterproof tube and covering the cable with the waterproof tube. Thereby, moisture can be prevented from entering the first case and the second case through the cable.

  In addition, a plurality of rotation operations are realized by providing the first shaft member and the second shaft member. At this time, the first shaft member houses the waterproof tube on the same axis as the first rotating shaft, and the second shaft member houses the waterproof tube on the same axis as the second rotating shaft, thereby waterproofing the tube. Is protected and its breakage is suppressed. Thereby, waterproofness is maintained.

  The hinge module disclosed in the present specification can realize a plurality of rotational operations while ensuring waterproofness.

It is preferable that the waterproof tube 5 has flexibility.

  One end portion 5 a of the waterproof tube 5 is connected to the first case 102, and the other end portion 5 b is connected to the second case 103. Thereby, the waterproof property of the mobile phone 101 is maintained.

  When the hinge module 1 is mounted on the mobile phone 101, the first case 102 can be rotated with respect to the second case 103 about the first rotation axis ax1 as shown in FIGS. Further, the first case 102 can be rotated with respect to the second case 103 by the second rotation axis ax2. Here, the rotation includes forward rotation and reverse rotation.

  The hinge module 1 has a first shaft member 6 that houses the waterproof tube 5 on the same axis as the first rotation axis ax1. The first shaft member 6 rotates the first bracket 2 with respect to the second bracket 3 on the first rotation axis ax1. The hinge module 1 also has a second shaft member 7 that houses the waterproof tube 5 on the same axis as the second rotation axis ax2. The second shaft member 7 rotates the second bracket 3 together with the first bracket 2 on the second rotation axis ax2. The hinge module 1 further includes a third shaft member 8 that rotates the second bracket 3 about the second rotation axis ax2.

  The first bracket 2 has a plate-like center portion 2a having a mounting hole 2a1 in which the first shaft member 6 is mounted. Moreover, it has the plate-shaped attachment part 2b by which the screw hole 2b1 for attaching to the 1st case 102 was drilled. The attachment portion 2b is continuously provided on both sides of the center portion 2a so as to project in a hook shape. The mounting hole 2 a 1 is located at the center of the first bracket 2.

The first shaft member 6 can be fixed to the second bracket 3 and rotatably mounted on the first bracket 2.

  The first shaft member 6 is a hollow cylindrical body and houses a part of the waterproof tube 5 therein. Since the waterproof tube 5 accommodated in the first shaft member 6 is protected by the first shaft member 6, the risk of breakage is reduced. Further, the central axis of the first shaft member 6 is matched with the first rotation axis ax1. The waterproof tube 5 is accommodated in the first shaft member 6 on the same axis as the first rotation axis ax1. For this reason, even if the 1st bracket 2 rotates, the waterproof tube 5 is not twisted. Also in this respect, the risk of damage to the waterproof tube 5 is reduced.

  The second shaft member 7 is mounted in a mounting hole 3b1 provided in the side plate 3b of the second bracket 3 so that the second bracket 3 can rotate. An attachment portion 9 for attaching the second bracket 3 to the second case 103 is provided on the side of the second shaft member 7. The attachment portion 9 is provided with a screw hole 9a.

  The cylindrical portion 11a has different diameters at the distal end portion 11a1 and the proximal end portion 11a2. That is, the diameter of the base end part 11a2 is enlarged compared with the diameter of the front-end | tip part 11a1. Thus, the connection of the waterproof tube 5 can be facilitated by reducing the diameter of the distal end portion 11a1, and a strong connection body of the waterproof tube 5 can be realized by increasing the diameter of the proximal end portion 11b2.

  The seal part 11 b is provided by fitting a rubber O-ring 13 into a groove part 12 a provided in the main body part 12. The material of the O-ring 13 is not limited to rubber, but may be other materials that can ensure sealing performance. Moreover, it can replace with mounting | wearing of the O-ring 13, and can also set it as the structure which provides a convex part in the periphery at the position corresponded to the groove part 12a, and fits this convex part in the cable insertion port 102c.

  The connection member 11 similar to the connection portion 5a is also attached to the connection portion 5b. Then, it is fitted into a cable insertion port 103 c provided in the second case 103. Since the connection of the connecting portion 5b to the second case 103 is common to the connection of the connecting portion 5a to the first case 102, detailed description thereof is omitted.

  As described above, the hinge module 1 of this embodiment includes the waterproof tube 5 that houses the cable 4 that is electrically connected to the electronic components 104 and 105 disposed in the cases 102 and 103. And the waterproof connection structure of the cable which has the connection member 11 provided in the waterproof tube 5 is provided.

  In the hinge module 1 as described above, the first shaft member 6 and the second shaft member 7 are first arranged so that the rotation axis ax1 and the second rotation axis ax2 are orthogonal to each other. As shown in FIG. 4, the hinge module 1 can rotate the first bracket 2 relative to the second bracket 3 about the first rotation axis ax1. This rotation operation is a rotation operation as if the first bracket 2 swings its head with respect to the second bracket 3. As shown in FIGS. 5 and 6, the hinge module 1 can rotate the first bracket 2 relative to the second bracket 3 about the second rotation axis ax2. This rotating operation is a rotating operation in which the first bracket 2 is bent with respect to the second bracket 3.

  Such a hinge module 1 is used for coupling the first case 102 and the second case 103.

  The first case 102 forms an information display unit of the mobile phone 101 and has a liquid crystal display surface 102a. The first case 102 has a cover surface 102b on the back side of the liquid crystal display surface 102a. The case itself is waterproofed. An electronic component 104 is arranged inside the first case 102. Further, the first case 102 has a cable insertion port 102c, and the cable 4 is drawn into the inside from the cable insertion port 102c. At this time, the cable 4 is housed in the waterproof tube 5, and the sealing portion 11b is fitted into the cable insertion port 102c as described above, so that waterproofness is ensured. The cable 4 drawn into the first case 102 from the cable insertion port 102c is connected to the electronic component 104 via a connector 4a provided at the tip thereof.

  The first bracket 2 included in the hinge module 1 is attached to the first case 102 as described above. The first bracket 2 is attached to the first case 102 via the attachment portion 2b.

  The second case 103 forms an operation unit for performing main operations of the mobile phone 101, and has an operation button surface 103a on which various operation buttons are arranged. The second case 103 is waterproofed on the case itself. An electronic component 105 is arranged inside the second case 103. The second case 103 has a cable insertion port 103c, and the cable 4 is drawn into the inside from the cable insertion port 103c. At this time, the cable 4 is accommodated in the waterproof tube 5, and the sealing portion 11b is fitted into the cable insertion port 103c as described above, so that waterproofness is ensured. The cable 4 drawn into the second case 103 from the cable insertion port 103c is connected to the electronic component 105 via a connector 4b provided at the tip.

  The second bracket 3 included in the hinge module 1 is attached to the second case 103 as described above. The attachment of the second bracket 3 to the second case 103 is performed via attachment portions 9 and 10.

  As described above, the cellular phone 101 in which the first case 2 and the second case 3 are coupled via the hinge module 1 realizes a plurality of rotational operations as shown in FIGS. That is, as shown by an arrow 31 in the figure, the first case 102 can be rotated with respect to the second case 103 about the first rotation axis ax1. By this rotating operation, the first case 102 is moved from the state in which the liquid crystal display surface 102a shown in FIG. 9 faces the same side as the operation button surface 103a to the cover surface 102b shown in FIG. 10 from the same side as the operation button surface 103a. It can be in a facing state.

  In addition, the mobile phone 101 can rotate the first case 102 relative to the second case 103 about the second rotation axis ax2 as indicated by an arrow 32 in the drawing. By this rotation operation, the first case 102 and the second case 103 can be opened, that is, the operation button surface 103a of the second case 103 can be opened. Further, the first case 102 and the second case 103 can be overlaid. At this time, the first case 102 is overlaid so that the liquid crystal display surface 102a is exposed to the outside or the cover surface 102b is overlaid so that the liquid crystal display surface 102a is exposed to the outside by combining the rotation operations on the first rotation axis ax1. Can be.

  Even when the mobile phone 101 performs such a single or complex rotating operation, the cable 4 is accommodated in the waterproof tube 5, and therefore is transmitted through the cable 4 into each case. Inflow of moisture can be suppressed. Since the waterproof tube 5 is housed in the first shaft member 6 and the second shaft member 7, the stress during the rotation operation is alleviated and the risk of breakage is reduced.

  In addition, the connection member 11 is used to attach the waterproof tube 5 to the first case 102 and the second case 103, so that waterproofness is ensured. In addition, the attachment work of the waterproof tube 5 becomes easy by employ | adopting the connection member 11. FIG. That is, since the connection member 11 can be picked at the time of attaching the waterproof tube 5, the attaching operation is facilitated. However, the waterproof tube 5 can be attached to the first case 102 and the second case 103 without using the connecting member 11. That is, as shown in FIG. 14, a cylindrical portion 102c1 is provided on the first case 102 side, and the cylindrical portion 102c1 can be mounted by being inserted so that the tip of the waterproof tube 5 is crowned. Thus, the waterproof tube 5 can be connected without using the connecting member 11.

  As described above, by using the hinge module 1 of the present embodiment, the waterproof property of the mobile phone 101 can be secured and maintained.

Further, by using the hinge module 1 of the present embodiment, the following effects can be further obtained.
That is, dustproofness can be ensured simultaneously with waterproofness maintenance.
Further, by making the hinge modular, it is possible to improve assemblability. When the cable is modularized, the cable 4 is included in the module, thereby further improving the assemblability of the mobile phone 101. Further, the cable 4 itself is housed in the first shaft member 6 and the second shaft member 7 in a form of being housed in the waterproof tube 5. For this reason, the passage route of the cable 4 is stably secured, and the cable 4 is not twisted or compressed unnecessarily, so that stable signal characteristics can be obtained.
Further, the cable 4 is accommodated in the waterproof tube 5 on the same axis as the first rotation axis ax1 and the second rotation axis ax2. For this reason, the cable 4 does not hinder the rotation of the hinge module 1 on the first rotation axis ax1 and the rotation on the second rotation axis ax2, thereby reducing the size of the hinge module 1 and thus the size of the electronic device. Can be achieved.
