Description

  TECHNICAL FIELD The present invention relates to a hinge device used for a pivoting portion of an electronic device such as a mobile phone or a notebook personal computer, and an electronic device using the hinge device.

  For example, a main unit provided with an operation unit is pivotally connected to a superposition unit provided with a display unit that is displayed by operation of the operation unit or a received signal, and the main unit is rotated by opening the superposition unit from the superposition blockage state. In an electronic device such as a mobile phone or a notebook personal computer that exposes and exposes the operation portion of the overlapping portion and the display portion on the lower surface of the overlapping portion, the hinge device used for this pivot connecting portion is, for example, one member. A bearing portion is provided in the connecting portion to be attached, a shaft portion is provided in the connecting portion attached to the other member pivotally attached thereto, and the shaft portion is connected to the bearing portion so that the shaft portion is pivotally supported.

  In this case, in order to realize a free stop that stops at the rotation position where the hand is released when the opening / closing rotation does not sway, for example, when the opening / closing rotation is performed by hand, the overlapping portion is not affected. There is a case where it is desired to configure so as to generate a large rotation resistance (rotation torque) that counteracts its own weight.

  Not only a hinge device in such an electronic device, but also a damper that realizes a free stop, automatically rotates by its own weight slowly, and prevents a predetermined rotation torque from being generated. There is a similar request in other hinge devices such as when it is desired to function as a device.

  Therefore, for example, the bearing portion side is a fixed side and the shaft portion side is a relative rotation so that sufficient rotation resistance is generated in the rotation of the bearing portion provided on one member side and the shaft portion provided on the other member side. Explaining it as a moving side, a rotating friction part that rotates together with the shaft part is provided in a superposed state with respect to a fixed part provided on the bearing part side, and the rotating friction part rotates in a superposed state with respect to the fixed part. Configure to generate resistance.

  In order to increase the rotational resistance of the rotational friction portion that overlaps with the fixed portion, at least one of them is slidably provided, and this is superposed by a spring provided on the shaft portion or the bearing portion. A method of increasing the rotational resistance by increasing the force is conceivable.

  However, it can be expected to increase to some extent, but it is not only limited, but if the spring force is simply increased and only the spring force is applied, the spring will be easily loosened. It may end up inferior in durability.

  In addition, it is conceivable to take a method of increasing the rotational resistance by applying irregularities or roughing to either or both surfaces of the fixed part and the rotational friction part that rotates relative to the fixed part. However, there is still a limit to generating sufficient rotational resistance while rotating, and as with the case of the spring described above, the surface may gradually become smoother as it is used. Inferior to sex.

  Therefore, in some cases, the surface resistance of the overlapping surface may be improved while being biased by a spring. However, in order to always improve the durability by generating a large rotational resistance without aging, a fixed plate serving as a bearing portion. And a plurality of rotating friction plates that are provided on the shaft portion and rotate relative to each other in a superposed state on the fixed plate, and are arranged in a stacked state to increase the total rotational friction between the fixed plate and the rotating friction plate. It is conceivable to increase the configuration.

  However, simply having such a configuration, for example, a configuration in which the fixing plate is projected one after another from a connecting portion in which a bearing portion is provided, in other words, a leg portion having a shape corresponding to the arrangement position of each fixing plate is provided. It must be configured to be connected to the part, making the production cumbersome, inferior in mass productivity, and high cost.

  The present invention finds such a problem and solves this by an epoch-making idea. The bearing portion is configured by providing a parallel-arranged locking shaft portion in parallel with the shaft portion on the member for providing the bearing portion. A plurality of fixing plates to be engaged with the parallel locking shaft portions may be slidable in the axial direction, but are fixed at least in a non-rotating state. Either a sliding friction plate provided slidably with respect to the locking shaft portion, or a rotational friction plate provided in a non-rotating state on the shaft portion, or slidable with respect to the shaft portion, or both slidably provided, and this may be a spring In this way, a rotation resistance is generated in the fixed plate and the rotation friction plate by superimposing the rotation, and a plurality of overlapping portions are provided in a stacked state so that a large rotation resistance is generated by the total rotation resistance. And each as described above The fixed plate is not projected from the connecting portion by a leg portion (connected portion) having a different shape to the connecting portion, but each fixing plate is also configured to be simply locked and fixed to the parallel locking shaft portion. All rotating friction plates can be manufactured as parts of the same shape, and a predetermined number of layers can be stacked according to the required rotation resistance (rotation torque) to adjust the rotation torque. It is an object of the present invention to provide a revolutionary hinge device and an electronic device using the hinge device that are less likely to cause a reduction in rotational torque due to the above, have excellent durability, are easily manufactured, and are excellent in mass productivity.

Therefore, when the shaft portion 4 rotates with respect to the bearing portion 3, each rotating friction plate 6 rotates together with the shaft portion 4 with respect to each fixed plate 5, and each fixed plate 5 and each rotating friction under superposition bias. A rotation resistance is generated by the rotation of the plate 6.

  Moreover, since the fixed plate 5 and the rotating friction plate 6 are stacked along the plurality of sets of shaft portions 4, a large rotation resistance (rotation torque) is generated by the sum of the rotation resistances.

A plurality of fixing plates 5 arranged side by side with a rotating friction plate 6 interposed between them 5 are locked at least against rotation by locking a rotation locking portion 9 provided on the fixing plate 5 to a side locking shaft portion 8. That is, since each fixing plate 5 provided as the bearing portion 3 on the first member 1 or the first connecting portion 1A is fixed to the side-by-side locking shaft portion 8 and fixed, the fixing plate 5 is also configured as the rotating friction plate 6. In the same manner as above, it can be composed of parts of the same shape.

  Each fixing plate 5 has, for example, a shaft support hole 12 through which the shaft portion 4 is inserted and a detent locking portion 9 that is fitted and locked to the parallel locking shaft portion 8, regardless of where the fixing plate 5 is laminated. They can be formed in the same plate shape.

  Accordingly, all the fixing plates 5 are provided with the same shape and can be assembled in the same manner, so that they can be easily manufactured and stacked, and the number of stacked layers can be easily increased.

  Therefore, large turning torque can be easily realized, there is little deterioration over time, and it has excellent durability, and it is easy to manufacture and mass-productive with a structure in which one or many fixing plates 5 can be easily stacked with a simple structure. It has a configuration that can excel in cost and reduce costs.
