Description

  The present invention relates to a hinge device having a rotation range (rotation region) with different rotation resistance (rotation torque), and an electronic device such as a mobile phone, a notebook computer, and a handy camera using the hinge device.

  Predetermined between the rotating shaft and the bearing so that it does not rotate freely due to wobbling or its own weight, or to achieve a free stop that stops when the hand is released, or to produce a desired damper action. In many cases, the rotation resistance (rotation torque) is generated.

  For example, when the first member and the second member are rotatably connected, the first member rotates with the rotation of the first member through a first connecting portion fixed to the first member. A rotation shaft portion is provided, and conversely, the second member is provided with a bearing portion that rotates together with the second member via a second connection portion, and the rotation shaft portion is pressure-bonded (press-fitted), for example. By providing a fitting portion to be fitted (embraced) in the bearing portion, when the second member is rotated with respect to the first member, the bearing portion is rotated with respect to the rotation shaft portion, and the fitted portion is A desired rotation resistance (rotation torque) is generated by sliding friction between the fitted surface and the outer surface of the rotation shaft portion.

  In order to increase the rotation torque while ensuring smooth rotation, for example, the rotation shaft portion is press-fitted into the bearing portion, and the shape of the fitted portion of the bearing portion and the shape of the rotation shaft portion are further changed. A predetermined rotation torque is generated by setting or selecting the resin material when the bearing portion is formed of resin and a metal or resin rotation shaft portion is press-fitted into the bearing portion.

  Conventionally, various proposals and improvements have been made for the configuration that can adjust the rotation resistance (rotation torque), but the hinge device that generates a different rotation torque in the rotation range with a simple configuration. No.

  That is, there is no hinge device having a rotation area with different rotation torques with a simple configuration.

  The present invention has a simple structure and is easy to assemble, and has a rotation region in which the rotation resistance differs depending on the rotation range, that is, the rotation torque is different. In a rotation range that generates torque and does not require a relatively large rotation torque, the rotation torque is small and it can be rotated smoothly with a light force. It is excellent in practicality, such as good performance and proper damper operation, and it is easy to set and use different rotation ranges with different rotation torques depending on the application. It is an object of the present invention to provide a revolutionary hinge device and an electronic device using the hinge device that have increased use and commercial value.

  Furthermore, the rotation resistance can be increased during the rotation, and the rotation torque is small from the start to the predetermined rotation position for both forward and reverse rotations. An object of the present invention is to provide an epoch-making hinge device and an electronic device using the hinge device that can be designed and set in various ways.

Alternatively, a bearing portion 4 that rotates along with the rotation of the first member 1 and is fitted on the rotation shaft portion 3 is provided, and the rotation shaft portion 3 is press-fitted into the bearing portion 4 to the bearing portion 4. Thus, a rotation resistance is generated when the rotation shaft portion 3 is relatively rotated, and a resistance increasing rotation portion 5 is press-fitted into both ends of the bearing portion 4 to the bearing portion 4. A rotation resistance is generated when the rotation portion 5 for increasing resistance is relatively rotated, and a pin-like action portion 7 is provided on the rotation shaft portion 3 to rotate the action portion 7. provided allowance portion 8 and to notched portion 8 tolerated in the resistance increasing for pivotal portion 5, the abutment portion 6 at both ends in the rotational direction of the notch portion 8 is provided, the first member 1 And in the course of rotating the second member 2, the abutment portion 6 provided on the resistance increasing for turning portion 5, said the working portion 7 which is provided on the pivot shaft portion 3 abuts bearing The resistance increasing rotation portion 5 is configured to rotate with respect to the portion 4, and a rotation range in which the rotation shaft portion 3 rotates with respect to the bearing portion 4, and the bearing portion 4.

In the rotation range in which relative rotation occurs until 7 abuts or one action portion 7 abuts one side surface of the abutment portion 6, only the rotation shaft portion 3 becomes a rotation resistance, Thus, the action part 7 is rotated relative to the rotation part 5 while the action part 7 is in contact with the abutting part 6, whereby the resistance increasing rotation part 5 is rotated together with the rotation shaft part 3. The pivot shaft 3 and the resistance increasing pivot section 5 serve as a pivot resistance, which can be either forward or reverse. Oite also relates to a hinge device according to claim 1, characterized by being configured as rotational resistance increases from the middle pivot.

Further, the rotation shaft portion 3 is press-fitted into the bearing portion 4, the resistance increasing rotation portion 5 is also press-fitted into the bearing portion 4, and is fitted on the rotation shaft portion 3. The hinge device according to any one of claims 1 and 2 is characterized.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  When the second member 2 is rotated with respect to the first member 1, for example, the first member 1 is provided via the first connecting portion 9 (in the embodiment described later, the second connecting portion 10 is connected to the second member 2. The rotating shaft 3 is provided on the second member 2 via the second connecting portion 10 (in the embodiment described later, the first connecting portion 9 is provided on the first member 1). The bearing unit 4 is rotated.

  That is, when the second member 2 is rotated with respect to the first member 1, the rotation shaft portion 3 is relatively rotated with respect to the bearing portion 4, but at least a part of the bearing portion 4 is at the rotation shaft portion 3. Since it is fitted, rotation resistance (rotation torque) is generated. Therefore, a rotation resistance is generated when the rotation shaft portion 3 rotates relative to the bearing portion 4.

  On the other hand, at the time of this rotation, the action portion 7 provided on the rotation shaft portion 3 is also turned together with the turning shaft portion 3, and the resistance increasing rotation portion 5 in which the action portion 7 is inserted into the bearing portion 4. When the abutting portion 6 is abutted, the resistance increasing rotation portion 5 rotates together with the rotation of the rotation shaft portion 3.

That is, not only the rotation shaft portion 3 but also the action portion 7 and the abutting portion 6 abut each other in the bearing portion 4 so that the rotation shaft portion 3 and the resistance increasing rotation are maintained with respect to the bearing portion 4 in this state. The part 5 will rotate relatively.

  Therefore, in the rotation range until the action part 7 hits the abutting part 6, only the rotation shaft part 3 is turned, but in the rotation range after the action part 7 hits the abutting part 6, the bearing part. 4, not only the rotation shaft portion 3 but also the rotation shaft portion 3 and the resistance increasing rotation portion 5 are rotated. For example, if the rotation resistance by the rotation shaft portion 3 is always set to be the same. The rotational resistance increases by the amount corresponding to the resistance increasing rotational portion 5 (for example, the sliding area increases as a whole).

  In this way, the rotation resistance changes (for example, increases) at the rotation position where the action portion 7 abuts against the abutting portion 6.

  Therefore, for example, the rotation portion 5 for increasing resistance together with the rotation shaft portion 3 is press-fitted into the bearing portion 4, and an action portion 7 that rotates together with the rotation shaft portion 3 is provided, and the action portion 7 is resisted at a predetermined rotation position. It can be configured such that the rotational torque is automatically increased from the predetermined rotational position only by setting so as to abut against the abutting portion 6 provided in the increasing rotational portion 5.

  As described above, the hinge device having the rotation regions with different rotation resistances can be realized with a simple configuration and simple assembly.

  Again, for example, the rotary shaft 3 is press-fitted into the resin-molded bearing 4 and is fitted on the rotary shaft 3 for compactness, or the rotary shaft 3 for reducing the diameter. The resistance increasing rotation portion 5 is also press-fitted into the bearing portion 4, and the resistance increasing rotation portion 5 rotates in conjunction with the rotation shaft portion 3 during the rotation of the rotation shaft portion 3. It can be realized simply by providing the action part 7 and the abutting part 6 so as to move (which constitutes this interlocking mechanism), and it can always be rotated by setting the action part 7 and the abutting part 6 as in the embodiment described later. From the dynamic starting position to the predetermined rotation position (0 to 120 degrees), the rotation resistance is small, and exceeding this (120 to 180 degrees) increases the rotation resistance. The rotation resistance is small from the dynamic starting position to the predetermined rotation angle, and then the rotation resistance automatically increases. Configuring is can be realized with a simple configuration.

  In addition, it can be configured so that the torque is always increased at the end of the rotation in both forward and reverse rotations, and the rotation torque at the end of the rotation at the end of the rotation is considerably increased to function as a stopper. It can also be designed to improve durability by over-rotating to absorb this load only when a load is applied.

  Specific embodiments of the present invention will be described with reference to the drawings.

For example, as shown in FIGS. 1 and 2, the main body 1 provided with the operation unit 11 is the first member 1, and the opening / closing unit 2 provided with the display unit 12 is the second member 2. This is an embodiment in which the present invention is applied to a mobile phone or a notebook personal computer that is connected to each other by a hinge device and rotated up and down from a superposition blockage state and rotated 180 degrees.

  That is, in the hinge device of the present embodiment, the second connecting portion 10 attached and fixed to the second member 2 (opening / closing portion 2) is provided with the rotating shaft portion 3 and attached to the first member 1 (main body portion 1). A bearing portion 4 that fits on the pivot shaft portion 3 is provided in one connecting portion 9, and a rotational resistance is generated by the frictional resistance of the pivot shaft portion 3 and the bearing portion 4 that fits on the pivot shaft portion 3. ing. The bearing portion 4 is formed by selecting and molding a resin that has excellent slidability and generates necessary frictional resistance, but has a good rotational feel and excellent sliding durability.

When the resistance increasing rotation portion 5 is rotatably inserted into both end portions of the bearing portion 4 (although it may be one side), the second member 2 is rotated with respect to the first member 1. The action portion 7 that abuts against the abutting portion 6 provided on the resistance increasing rotation portion 5 and rotates the resistance increasing rotation portion 5 together with the rotation shaft portion 3 with respect to the bearing portion 4. The rotation shaft portion 3 is provided with a rotation range until the action portion 7 abuts against the abutting portion 6, and the rotation shaft portion 3 and the resistance increasing rotation portion 5 abut against each other. The rotation resistance is different depending on the rotation range in which the portion 4 rotates together.

  That is, in this embodiment, when the metal rotation shaft portion 3 is press-fitted into the resin bearing portion 4 and the rotation shaft portion 3 rotates relative to the bearing portion 4, the rotation feeling is moderate. Further, a rotation resistance having good durability is generated, and a metal resistance increasing rotation portion 5 is further press-fitted into both ends of the bearing portion 4 so that the resistance against the bearing portion 4 is increased. A rotation resistance is generated when the increasing rotation portion 5 is relatively rotated, and the rotation shaft 3 rotates in the rotation range until the action portion 7 comes into contact with the abutting portion 6. In the rotation range in which the action portion 7 abuts against the abutting portion 6 and the rotation shaft portion 3 and the resistance increasing rotation portion 5 rotate together only by dynamic resistance, the rotation shaft portion 3 In addition to the rotation resistance, the rotation resistance of the resistance increasing rotation portion 5 is added, and the rotation resistance is increased by increasing the sliding area.

  Furthermore, in this first embodiment, the resistance increasing rotation portion 5 is fitted into both ends of the bearing portion 4, but the interlocking mechanism between the resistance increasing rotation portion 5 and the rotation shaft portion 3 is for increasing resistance. The rotation portion 5 and the rotation shaft portion 3 are not juxtaposed in the bearing portion 4, but the resistance increasing rotation portion 5 is fitted and fixed to the end portion of the rotation shaft portion 3 (non-rotating). The rotation shaft portion 3 is press-fitted into the bearing portion 4 and the resistance increasing rotation portion 5 is press-fitted into the bearing portion 4 at the end of the bearing portion 4, that is, the rotation shaft portion 3 and the resistance. The increase turning part 5 is configured to be fitted. Therefore, it is configured to be compact and sufficiently increase the torque.

  Then, a projecting (for example, pin-shaped) action portion 7 is provided on the rotation shaft portion 3, and an abutting portion 6 against which the resistance increasing rotation portion 5 abuts constitutes an interlocking mechanism.

  In other words, in the first embodiment, the notch portion 8 as the allowance portion 8 that allows the action portion 7 to rotate relative to the resistance increasing rotation portion 5 that is fitted and fixed to the end portion of the rotation shaft portion 3. By providing both end portions in the rotational direction of the permissible portion 8 (notch portion 8) as the abutting portion 6, the action portion 7 is relatively rotated in the notch portion 8, and the rotation is forward or reverse. Even in the direction, in the range of rotation until the action part 7 comes into contact with the one abutting part 6, only the turning shaft part 3 becomes a turning resistance, and the action part 7 rotates relative to the one abutting part 6. The resistance increasing rotation portion 5 is rotated together with the rotation shaft portion 3 by rotating in a state of being in contact with the rotation shaft portion 3, and the rotation resistance by the rotation shaft portion 3 and the resistance increasing rotation portion 5 is reduced. Thus, the rotational resistance increases in the middle of the rotation in both the forward and reverse rotation directions.

  More specifically, an action portion 7 is provided on the turning shaft portion 3 in a direction perpendicular to the axial direction, and the notch portion 8 is used as the allowance portion 8 that allows the action portion 7 to turn. It is provided in the increasing rotation part 5 and abuts on both ends in the rotation direction of the notch part 8 in the middle of the rotation of the rotation shaft part 3 and rotates the resistance increasing rotation part 5 together with the rotation shaft part 3. The abutting portion 6 is provided as an interlocking mechanism to be moved.

  Accordingly, the resistance-increasing rotation portion is placed on the rotation shaft portion 3 so that the action portion 7 provided as a projection portion that rotates together with the rotation shaft portion 3 is accommodated in the notch portion 8 of the resistance-increasing rotation portion 5. 5 is press-fitted into the bearing portion 4, and the rotational torque is always small within a predetermined rotational range (0 to 120 degrees in the illustrated embodiment) in both forward and reverse rotational directions. When the action part 7 abuts against the abutting part 6 at the end of the notch part 8, the pivoting part 3 and the resistance increasing pivot part 5 are rotated together so that the remaining pivot range is reached. The torque is increased at (120 degrees to 180 degrees).

The acting portion 7 of the projections may be provided by press-fitting the spring pin is erected on the pivot shaft portion 3 may be integrally protruded As shown as another example, protrusions A washer may be provided so as to be fitted.

  Further, in this embodiment, the rotating shaft portion 3 is provided with the action portion 7 as a projection portion, but a plurality of the action portions 7 are provided on the turning shaft portion 3 as in the illustrated second embodiment (for example, illustrated) The contact portion 6 is formed as a protrusion between the rotation directions of the action portion 7, and the action portion 7 and the rotation shaft portion 3 are rotated relative to each other in the same manner as in the first embodiment. By moving, one action part 7 abuts against one side of the abutting part 6 so that the turning shaft part 3 and the resistance increasing turning part 5 rotate together. It may be configured such that the abutting portion 6 abuts on the opposite side of the abutting portion 6 and the rotation shaft portion 3 and the resistance increasing rotation portion 5 rotate together.

  In the third embodiment, a resistance increasing rotation portion 5 is provided in parallel with the rotation shaft portion 3 in the bearing portion 4, and the rotation shaft portion 3 and the resistance increasing rotation portion 5 are abutted. It is the structure which provided the interlocking mechanism in the part.

  For example, in the illustrated third embodiment, a pin-like action portion 7 is provided at the end portion of the rotation shaft portion 3, and a notch portion 8 that forms a butting portion 6 is provided at the end portion of the resistance increasing rotation portion 5. For example, when rotating together with the rotation shaft 3, the action portion 7 abuts against the abutting portion 6 at one end of the notch 8, and the rotation shaft 3 and the resistance increasing rotation portion 5 rotate together to rotate in reverse. When the action part 7 moves, the turning shaft part 3 and the resistance-increasing turning part 5 co-rotate against the abutting part 6 at the opposite end, and the turning torque is increased from the middle of any turning. It is configured to do.

  Further, in the illustrated fourth embodiment, the relationship between the action portion 7 and the abutting portion 6 in the third embodiment is an opposite embodiment, and two action portions 7 are cut out at the end of the rotating shaft portion 3. And a pin-like butting portion 6 disposed between the action portions 7 is projected at the end of the resistance increasing rotation portion 5.

  In addition, a plurality of resistance increasing rotation parts 5 that are press-fitted into the bearing part 4 via an interlocking mechanism between the rotation shaft part 3 and the action part 7 and the abutting part 6 may be provided. Even if the rotation torque is changed by co-rotation of the increasing rotation portion 5, and the rotation rotation portion 5 for increasing resistance further rotates together, the rotation torque is further increased. good.

  As in these embodiments, the interlocking mechanism between the rotation shaft portion 3 and the resistance increasing rotation portion 5 can be designed in various ways.
