Description

  The present invention relates to, for example, a hinge device provided at a pivotal portion of a folding electronic device such as a mobile phone or a notebook computer, and an electronic device using the hinge device.

  When the ends of two members are connected by a hinge device and the other is configured to be rotatable with respect to one, the hinge device is simply provided on one member in a flush state, and the other device is connected via the hinge device. When the members are connected, even if the other member is rotated with respect to one member, both members cannot be brought into a superposed state.

  That is, for example, when plate members having a predetermined thickness are overlapped with each other and the other member is configured to turn up and down 180 degrees or nearly 180 degrees with respect to one member, the ends of both members are A hinge device is incorporated between the parts, and this hinge device has a bearing portion or a shaft portion or a mounting portion for attaching these members protruding above the end portion of one member, and a shaft portion or a shaft portion provided on the other member. A bearing unit or a hinge device in which these are assembled is attached so as to be able to rotate to a state where they overlap each other. In any case, the shaft portion of the hinge device cannot be closed in a superposed state unless it is installed at a position protruding to the opposite side with respect to any member.

  Therefore, as shown in FIG. 18 (a), in order to be able to be in a superposed state, the hinge device 30 must be provided so as to protrude upward with respect to one member 31. In the open state where the other member 32 is opened and rotated by 150 to 180 degrees with respect to one member 31 and the both members 31 and 32 are connected in a straight line, for example, the intermediate device protrudes by the hinge device 30. A part is formed, and both open surfaces are not flush with each other, resulting in a stepped portion, which does not become a flat open continuous surface when opened.

  More specifically, for example, from the state in which the opening / closing part 32 provided with the display part is superposed on the main body part 31 provided with the operation part on the surface, such as a mobile phone or a personal computer, the operation part, display part and The end portions of the main body 31 and the opening / closing portion 32 are connected via the hinge device 30 so that they can freely rotate up and down until they are exposed to each other. In order to do so, as described above, the hinge device 30 cannot be placed in a flush state between the end portions of the main body 31 and the opening / closing portion 32, for example, in a protruding state above the end of the main body 31. Mounting portions for incorporating the hinge device 30 were provided on the left and right sides, and the hinge device 30 provided at the end of the opening / closing portion 32 was assembled between the mounting portions, so that the hinge device 30 had to be configured to be freely rotatable by 180 degrees from the overlapped state. .

  Therefore, although they can be overlapped with each other, since the opening / closing part 32 is connected via the hinge device 30 protruding above the end of the main body part 31, both open surfaces are flush even when rotated 180 degrees. There is no flat surface, and the hinge device 30 exists in a protruding state from the end of the main body 31 at the base of the opening / closing part 32.

Japanese Patent Application No. 2004-243962

  Therefore, the applicant can put the hinge device in an overlapping state as shown in FIG. 18B and turn the hinge device up and down 180 degrees so that the open surfaces of the hinge devices are flush with each other (flat surface). In order to configure, it has been found that the hinge device 40 has a biaxial configuration.

  That is, for example, by installing and connecting a parallel biaxial hinge device 40 between the end of one member 31 and the end of the other member 32, the other member 31 is connected to the other member 31 by the two shafts 41 and 41. When the member 32 is swung up and down and the other member 32 is turned 180 degrees from the state where the members 32 are overlapped with each other, for example, the open surfaces of both the members 31 and 32 become a flat open surface. Further, for example, if the biaxial hinge device 41 is limited to a size within the plate thickness of both the members 31 and 32, the hinge device 40 that forms a flat open surface with no protrusion at the middle portion can be obtained. The used openable / closable electronic device can be realized.

  Further, by adopting a biaxial configuration, the other member 32 can be rotated up and down 360 degrees with respect to the one member 31, and the other member 32 is superposed on one surface of the one member 31 and is opposite to the one member 31. It becomes a structure which can implement | achieve easily the structure which can be rotated to the state which superimposes the other member 32 on the surface.

  However, simply increasing the number of shafts to two causes the two shafts 41 and 41 to rotate without any restriction, and thus causes a problem that the other member 32 fluctuates with respect to one member 31.

  Even if a free stop that stops when the hand is released by generating torque with respect to the rotation of each of the two shafts 41 and 41 so that this wobble does not occur, each shaft 41 and 41 each Since it rotates, it cannot be smoothly rotated to a desired position.

  Although the present invention is a hinge device that can be in a superposed state as a biaxial configuration, the hinge device is not in a position that protrudes at the center when it is turned and opened, and both members are opened. The surface can be configured to be substantially flush with the hinge device so that it can be accommodated so as not to be substantially flush with or projecting from the open surface. Using a hinge device and a hinge device having an epoch-making structure that enables the rotation amount of the member with respect to the biaxial hinge device to be smoothly rotated without wobbling by restricting the amount of rotation relative to the complete synchronous rotation. The purpose is to provide electronic devices.

  In order to solve the technical problem, the applicant has already filed Japanese Patent Application No. 2004-243966 (Patent Document 1) using a geared connection by a gear as a synchronization means. The (gear) type produces a “gritty” feel on the gear teeth and has an uncomfortable operation feeling, and further increases the gear diameter by reducing the pitch between shafts and reducing the size. If it is made smaller, an intermediate gear is required, and in this respect, the cost is high, the assembly is troublesome, the mass productivity is inferior, and the space can not be saved (the set cannot be made thin).

  The present invention solves the disadvantages of this gear type, has a freedom in the pitch between shafts and occupied space, is less expensive, saves space, and is further improved. An object is to provide an electronic device using the apparatus.

  The gist of the present invention will be described with reference to the accompanying drawings.

  The hinge base 3 is disposed between the first member 1 and the second member 2, and the end of the first member 1 and the hinge base 3 are pivotally attached via the first rotating shaft portion 4. The hinge base 3 and the end of the second member 2 are pivotally connected via the rotary shaft 5, and the first member 1 is connected to the intermediate hinge base 3 via the first rotary shaft 4. The second member 2 is provided on the hinge base 3 via the second rotation shaft portion 5 so as to be able to swing up and down.

  Therefore, the second member 2 can be rotated up and down with respect to the first member 1 via two axes (the first rotation shaft portion 4 and the second rotation shaft portion 5).

  Therefore, for example, by setting the distance between the two parallel axes, that is, the length dimension of the hinge base 3, the two members between the end portions of the first member 1 and the second member 2 as shown in FIG. Even if the hinge base 3 provided with the shaft is disposed and the first member 1 and the second member 2 are opened, the opening surface is designed to be substantially flat without a large protruding portion or stepped portion, The hinge base 3 is also rotated by the biaxial rotation and the parallel biaxial position is also rotated with respect to the first member 1, so that the first member 1 and the second member 2 are rotated in a superposed state.

  That is, each axis does not rotate freely, and the first rotation shaft portion 4 is always connected to the first rotation portion 6 and the second rotation portion 7 by the interlocking link portion 17. The second rotation shaft portion 5 is rotated, and the first member 1 is rotated relative to the hinge base 3 as shown in FIGS. 7, 8, 9, 11, 12, and 13. Accordingly, since the second member 2 always rotates relative to the hinge base 3, the second member 2 is rotated via the hinge base 3 having two axes with respect to the first member 1. When this is done, it can be smoothly rotated to a desired position without wobbling.

  In addition, in the present invention, the interlocking link portion 17 is disposed at an axial extension position on the axially outer side from one side end portions of the first rotation shaft portion 4 and the second rotation shaft portion 5, and The interlocking link portion 17 does not interfere with the first rotation shaft portion 4 and the second rotation shaft portion 5 when the second member 2 is rotated 180 degrees or more with respect to the first member 1. Therefore, even if the second member 2 is rotated 180 degrees or more with respect to the first member 1, the interlocking link portion 17 does not interfere with the first rotation shaft portion 4 and the second rotation shaft portion 5. The first member 1 and the second member 2 can be reliably and smoothly rotated 360 degrees.

When the two members 2 rotate up and down from the closed position where the first member 1 and the second member 2 overlap and rotate in the opening direction to become the opening position, the first rotating portion 6 or the second member 2 When the rotating portion 7 is relatively rotated along with the opening rotation, the turning force is transmitted by the bar base 17A as a pushing force or a pulling force, so that the second rotating portion 7 or the first rotation is transmitted. The portion 6 is set at an eccentric position where the second member 2 with respect to the hinge base 3 or the hinge base 3 with respect to the first member 1 rotates in synchronization with the same opening direction. .

  In this embodiment, the interlocking link portion 17 is disposed at an axial extension position on the outer side in the axial direction from the one side end portions of the first rotation shaft portion 4 and the second rotation shaft portion 5, The interlocking link portion 17 does not interfere with the first rotation shaft portion 4 and the second rotation shaft portion 5 when the second member 2 is rotated by 180 degrees or more with respect to the first member 1. It is said.

  Specifically, the first rotating part 6 is provided at one end of the first rotating shaft part 4 and the second rotating part 7 is provided at one end of the second rotating shaft part 5. The first rotating portion 6 and the second rotating portion 7 of the first rotating shaft portion 4 and the second rotating shaft portion 5 are located on the outer side in the axial direction, By arranging the interlocking link portion 17 and providing the interlocking link portion 17 between the first rotating portion 6 and the second rotating portion 7, the interlocking link portion 17 is connected to the first rotation portion. The moving shaft portion 4 and the second rotating shaft portion 5 are arranged at axial extension positions on the outer side in the axial direction from one end portion of the second rotating shaft portion 5.

  More specifically, the attachment portion 17B of the interlocking link portion 17 is connected to the first rotation shaft portion 4 and the second rotation shaft portion 5 with respect to the first rotation portion 6 and the second rotation portion 7. The bar base body 17A is arranged at one side end of the first rotation shaft portion 4 and the second rotation shaft portion 5 by being mounted in a projecting state toward the axial extension direction outside the side end portion in the axial direction.

The diameters of the second rotation shaft portion 5, the first rotation portion 6, and the second rotation portion 7 are also substantially equal to the thicknesses of the first member 1 and the second member 2, and the first member 1 of the hinge base 3 In the open state in which the first rotation shaft portion 4 and the second rotation shaft portion 5 are arranged in parallel on the side and the second member 2 side, respectively, and the second member 2 is opened to the first member 1, for example, 160 degrees. The first member 1 and the second member 2 have a substantially flat open surface with no protrusions at least 1.5 times the thickness of the members 1 and 2 at the pivoting portion between the first member 1 and the second member 2. The first member 1 and the second member 2 are configured to be continuously formed by two members, and can be closed and rotated to a superposed state where the open surfaces of the first member 1 and the second member 2 are combined with each other.

Although the first rotating shaft portion 4 is not completely synchronized with the shaft, the first rotating shaft portion 4 is rotated by 45 degrees in the synchronizing direction and substantially synchronously rotated. Subsequently, the second member 2 is moved with respect to the hinge base 3 by the second rotating shaft. When the portion 5 is turned about 68.3 degrees, the hinge base 3 is also turned about 91.7 degrees about the first turning shaft portion 4 with respect to the first member 1 so that the first member 1 is rotated. On the other hand, the 2nd member 2 rotates 160 degree | times, and it can be set as an open state as shown in FIG. 9, FIG.
