Description

  The present invention relates to a hinge device that pivotally attaches a first member and a second member, and an electronic device using a hinge device such as a mobile phone or a notebook computer.

  In particular, the present invention relates to a structure for generating a rotational resistance in this hinge device.

  The hinge device is configured so as to generate a predetermined torque by generating a rotation resistance when opening and closing due to various demands.

  For example, when the second member is rotated with respect to the first member, a so-called free stop that stops at a position where the hand to be rotated is released by generating a rotation resistance that can resist the weight of the second member. It is desirable to generate a rotation resistance that can be realized, or to generate a damper function before the closed position so that it does not close rapidly by accelerating due to its own weight.

  In addition to such a case, for example, a rotation bias is generated by, for example, a torsion spring, and the lock is released by operating a lock release button or switch to resist its own weight by the torsion spring. Even when the second member is configured to automatically rotate with respect to the first member, this automatic rotation speed is accelerated. In particular, if the second member rotates more than 90 degrees, its own weight is added to the torsion spring, and the momentum increases to open the rotation. In the case of a sudden stop at the open rotation position by hitting the stopper at the rotation open position (fully open position) or by clicking engagement, it may cause a serious impact or cause durability. I also found that there was an inferior problem.

  In particular, when performing this opening and closing operation with a hand such as a mobile phone, it may be dropped or dropped from the hand due to inertia due to this momentary opening rotation or sudden stop due to a stopper or click engagement, In order to solve such a problem, it is desirable that the vehicle is decelerated by a large rotation resistance (brake) in the range before the rotation opening position.

  In addition, even when closed as described above, there is a case where the polymerization is blocked with vigor due to its own weight, spring force, or closing bias by click engagement. In order to buffer this, not only before the fully open position but also before the closed position, if it is closed slowly so as to generate a rotational resistance (brake), a high-class feeling is also produced.

  Conventionally, as a method of increasing the rotation resistance in order to solve such a demand and the above-described problem, an oil damper is provided, or the rotation shaft portion is crimped and held by, for example, a C-shaped bearing portion to provide a large rotation resistance. A click engagement mechanism is provided that can be generated or detachably engaged with each other at a predetermined rotation position, and the cam portion is configured to rotate relative to one cam engagement portion to engage with the unevenness. Increase the rotation resistance in the rotation range where the cam is not engaged, such as by strengthening the cam engagement spring that energizes and urges the part to the cam engagement part or increasing the rotation resistance at the rubbing surface. However, if this rotational resistance is too large, there may be cases where the free stop can be realized, but it may not be able to rotate smoothly. May be damaged, Be made to produce a switching of rotational resistance has been difficult in any configuration.

  In addition, it has not been possible to easily realize a configuration in which an appropriate rotation resistance is generated only in a rotation range where the brake is to be applied, instead of a rotation resistance generated in the entire region.

  According to the present invention, an appropriate rotation resistance can be obtained with a very simple configuration by fitting and arranging a crimping portion such as a coil spring on the rotation shaft portion and providing a stopper portion that rotates relative thereto. It can be easily obtained, and the rotation resistance can be obtained in a predetermined rotation range or rotation direction. For example, the rotation resistance is generated from a predetermined rotation position, or the rotation resistance is generated in a predetermined rotation direction. It is possible to realize an appropriate rotation resistance only within a predetermined rotation range, or to increase the rotation resistance before and after the predetermined rotation range with a simple configuration, which makes it close to the fully open position. Can generate a rotation resistance only at the position, or can generate an appropriate rotation resistance only near both the closed position and the fully open position. For example, the opening rotation speed tends to increase beyond a predetermined rotation position. Rotation resistance occurs in the rotation range, as described above For example, even when automatic opening rotation is performed by a torsion spring or when opening and rotation is facilitated by a torsion spring, rotation is performed in the range before the rotation opening stopper position and the rotation opening click engagement position at the fully opened position. An object of the present invention is to provide an innovative hinge device and an electronic device using the hinge device that are easy to handle without causing the above-described problems due to a deceleration action caused by dynamic resistance.

  In addition, as described above, a rotational resistance is generated only in a predetermined rotational range without applying a constant rotational resistance in the entire rotational region, so that, for example, the rotational speed is increased by the weight of the member to be rotated. Electronic equipment using a revolutionary hinge device that can generate a rotational resistance within the range to be struck to make it constant speed or decelerate, and the rotational range before the fully open position and the rotation before the closed position Another object of the present invention is to provide an epoch-making hinge device and an electronic device using the hinge device that can easily realize a configuration in which, for example, a substantially constant rotation resistance is generated depending on the movement range, and each rotation resistance has a different magnitude. It is said.

For example, a rotation resistance is generated from a predetermined rotation position, an appropriate rotation resistance is generated only in a predetermined rotation range in a predetermined rotation direction, or the rotation resistance increases before and after the predetermined rotation range. As described above, it can be realized with a simple configuration. As a result, a rotational resistance is generated only near the fully open position, or appropriate rotation is performed only near both the closed position and the fully open position. Therefore, a rotation resistance is generated only in a predetermined rotation range without applying a constant rotation resistance in the entire rotation area, and the rotation speed is increased by the weight of the member to be rotated, for example. Cause rotation resistance in the range to be An innovative hinge device and electronic apparatus using the hinge device can be or is decelerated or as fast.

  In the inventions according to claims 2 to 7, the present invention can be easily realized with a simpler structure. In particular, in the inventions according to claims 2, 3 and 4, the simple structure is more than a predetermined rotational position. An appropriate or substantially constant rotation resistance can be generated reliably in the rotation range. In particular, in the inventions according to claims 3 and 4, the crimping portion is constituted by a coil spring, and this is closely fitted and rotated. The dynamic resistance is not a mere deformation elasticity, but one end of the coiled coil spring is locked from the free rotation to the stopper portion, thereby causing a sliding resistance with the rotation shaft portion, thereby generating a rotation resistance. It is easy to manufacture with an extremely simple configuration, and can produce sufficient rotational resistance reliably. Also, a substantially constant rotational resistance is applied to the predetermined times instead of a proportionally proportional rotational resistance according to the amount of rotation. Easy to generate in the moving range If the one end and the stopper are locked and rotated even during reverse rotation, the coil spring will be weakened and the coil spring will be tightened.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS 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, the rotation shaft portion 4 is rotated with respect to the bearing portion 3. At this time, the crimping portion 5, for example, the coil spring 5 is provided in a fitted state on the outer periphery of the rotating shaft portion 4. The coil spring 5 is, for example, inserted and locked at its end, welded, or not locked or bonded as in the embodiments described later, but simply wound and pressure-bonded, that is, brought into close contact, and in an elastic state As a result, the coil spring 5 rotates together with the rotating shaft portion 4.

  On the other hand, a stopper portion 6 is provided on a member that rotates relative to the rotating shaft portion 4 and the crimping portion 5, such as a bearing portion 3 that rotates relative to the rotating shaft portion 4, or the like. Similarly, the first member 1 or the second member 2 in which the bearing portion 3 is provided in the non-rotating state is provided with the stopper portion 6 in the non-rotating state. The stopper portion 6 rotates relative to the rotation shaft portion 4 and the crimping portion 5, and the locking end portion 5 </ b> A of the crimping portion 5, for example, one end portion 5 </ b> A of the coil spring 5 is pivotally locked.

  That is, for example, the stopper forming member 6B is provided so as to rotate relative to the coil spring 5 and the rotating shaft portion 4, and the stopper portion 6 is provided by providing, for example, a butting portion 6A at this predetermined position.

  Accordingly, when the second member 2 is rotated with respect to the first member 1, the rotation shaft portion 4 is rotated with respect to the bearing portion 3, and the coil spring 5 is rotated with respect to the stopper portion 6. 6 and one end portion 5A of the coil spring 5 are locked and further rotated, the one end portion 5A of the coil spring 5 is locked to the stopper portion 6, so that the coil spring 5 is deformed so that the coil spring 5 is slightly wound around the stopper portion 6. The pressure-bonding degree is further increased (when the reverse rotation is performed, the pressure-bonding degree is weakened by being deformed so as to be wound up). Then, the coil spring 5 is prevented from rotating, and the rotating shaft portion 4 is rotated with respect to the coil spring 5, and a sliding resistance due to the crimping of the coil spring 5 occurs. As described above, when the coil spring 5 is further rotated from the position where the one end portion 5A of the coil spring 5 and the stopper portion 6 are locked, pressure friction on the rotation shaft portion 4 is generated in this way, thereby causing a large rotation resistance. Become.

  For example, an abutting portion 6A where the one end portion 5A of the coil spring 5 abuts is simply provided as the stopper portion 6, and the one end portion 5A of the coil spring 5 is relatively rotated with respect to the abutting portion 6A so as to be in contact with and separated from the abutting position. When one end 5A hits the butting portion 6A and further rotates, the rotating shaft 4 rotates with respect to the coil spring 5 by rotating in this butting (locked state). The pressure-bonding friction between the moving shaft portion 4 and the coil spring 5 becomes a rotation resistance, and further, for example, by slightly deforming in the direction in which the coil spring 5 is wound and tightened, the degree of pressure-bonding to the rotation shaft portion 4 becomes larger than in the case of reverse rotation. A large rotational resistance occurs.

  Therefore, for example, if the rotation position of the stopper portion 6 with respect to the one end portion 5A of the coil spring 5 is set, the position and rotation range where the rotation resistance is generated can be set. A pair of stopper portions 6 are provided, and one end of the coil spring 5 is provided therebetween. If the portion 5A is positioned, no rotation resistance is generated in the range of rotation between the stopper portions 6, and the rotation by the coil spring 5 is performed in the rotation range of the rotation while being locked to the stopper portion 6. It can be configured to generate dynamic resistance.

  In addition, as described above, when the coil spring 5 is rotated in the winding direction and when the coil spring 5 is rotated in the unwinding direction, the pressure-bonding force of the coil spring 5 to the rotating shaft portion 4 increases or decreases. In this case, it can be easily realized that a large rotation resistance, that is, a strong brake is generated, and a small brake is generated in the closed rotation.

  That is, the rotation resistance can be automatically changed according to the rotation direction as described above. For example, a strong brake is generated in the range before the click engagement at the fully open position in the opening direction, and a weak brake is generated in the range before the reverse closed position. It can also be easily realized to generate.

  For example, in the case where the opening rotation bias is generated by the torsion spring, a large brake is required in the range before the fully open position because the weight of the member to be released and the rotation bias are applied, and conversely the closing direction However, a weak brake can be used because the open rotation bias acts as a closing resistance, but even in such a case, this strong and weak brake can be easily applied within the required rotation range. It can only occur in the required direction.

  Thus, according to the present invention, it is possible to easily generate a rotation resistance in a predetermined rotation range, and it is easy to set the rotation range and the rotation direction for generating the rotation resistance. In this way, the crimping part resistance pivoting range by the crimping part 5 can be generated in the front and rear range of the free pivoting range, and in particular, it is easy to manufacture and can surely produce a large pivoting resistance. The orientation can be easily adjusted and set.

  Therefore, for example, the problem caused by the fact that the rotational speed is increased by automatically generating a rotational resistance only in a range where the opening rotational speed is increased by its own weight or a torsion spring in the range before the fully opened position. In addition, for example, a rotational resistance (brake) can be generated in the range before the closing position where the weight is to be closed due to its own weight. In addition, an innovative hinge device and an electronic device using the hinge device that can easily realize that the brake at the time of closing is weaker than the brake at the time of opening.

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

  This embodiment is a case where the present invention is applied to a hinge device of a mobile phone. A main body portion provided with an operation portion is a first member 1, and a superposition portion provided with a display portion is a second member 2. From the state in which the ends of the overlapping portion 2 and the overlapping portion 2 are pivotally attached to each other by a hinge device, and the overlapping portion 2 is overlapped and closed to the main body portion 1, the overlapping portion 2 is swung up and down approximately 180 degrees to turn to the rotation open position (fully open position). ) To open and rotate.

  In this embodiment, the main body portion 1 and the overlapping portion 2 are connected by a left and right main hinge device and a left and right auxiliary hinge device according to this embodiment, and the auxiliary hinge device is simply connected to the bearing portion. In this embodiment, the main hinge device on one side of such a mobile phone may be configured by a rotating shaft portion or may incorporate a torsion spring that biases to open and rotate as will be described later. Is a hinge device according to the present invention, and a coil spring rotation resistance mechanism C is provided on the hinge device so that the coil spring 5 can rotate between a range before the closed position when rotating in the closing direction and a range before the fully opened position when opening. Dynamic resistance is generated, and during this time and in different rotation directions, no rotation resistance is generated by the coil spring 5.

  That is, in this embodiment, the first member 1 includes a bearing portion 3 provided in a non-rotating state, and the second member 2 includes a rotation shaft portion 4 provided in a non-rotating state and pivotally supported by the bearing portion 3. A coil spring 5 is provided as a crimping part 5 in a fitted state on the outer periphery of the rotating shaft part 4, while the first member 1 is provided with an end 5A for locking the crimping part 5, that is, one end of the coil spring 5 in this embodiment. A stopper portion 6 is provided to which the portion 5A is relatively moved and locked, and in this locked state, the rotation of the rotating shaft portion 4 with respect to the coil spring 5 is further rotated by pressure-bonding of the coil spring 5. A rotation resistance mechanism C that generates dynamic resistance is provided.

  That is, the stopper portion 6 may be provided on the bearing portion 3 or a member that rotates the bearing portion 3, but in the present embodiment, the stopper portion 6 is provided in the first member 1 in the same non-rotating state as the bearing portion 3. A coil spring 5 that rotates together with the rotation shaft portion 4 in a fitted state is elastically attached to the rotation shaft portion 4 that rotates relative to the bearing portion 3 and the stopper portion 6. On the other hand, by rotating the second member 2, the coil spring 5 is integrally rotated with the rotation shaft portion 4 and is rotated with respect to the stopper portion 6. At this time, one end portion 5 </ b> A of the coil spring 5 is within a predetermined rotation range. In the rotation range beyond the predetermined rotation range without being locked to the stopper portion 6, it is locked to the stopper portion 6, and further rotated in this direction in this locked state, this time with respect to the coil spring 5. The rotating shaft 4 is rotated, and the coil spring 5 is rotated by the rotating shaft 4. The rotation resistance is generated by the sliding resistance due to the impact, and the coil spring 5 and the rotation shaft portion 4 are both freely rotated and the coil spring 5 is locked by the stopper portion 6. Thus, the rotation resistance mechanism C is configured so that the rotation shaft portion 4 is rotated relative to the coil spring 5 to generate a crimping portion resistance rotation range in which the rotation resistance is generated.

  As described above, the crimping portion 5 may employ a C-shaped holding tube to be crimped or a press-fit fitting cylinder to be press-fitted, but in this embodiment, it is easy to manufacture and assemble, and a strong sliding resistance is generated. The coil spring 5 whose sliding resistance is surely increased or decreased depending on the rotation direction is attached to the outer periphery of the rotation shaft portion 4 and is elastically attached, and one end portion 5A of the coil spring 5 is bent at the tip portion. Is fixed to the end positioning portion 12 and the end of the one end portion 5A that is positioned and held is used as the locking end portion 5A that is locked to the stopper portion 6.

  In other words, the coil spring 5 is tightly fitted on the rotation shaft portion 4, and the rotation shaft portion 4 and the coil spring 5 are configured to rotate integrally only with this contact force. Accordingly, it is configured such that a substantially constant strong rotation resistance is generated in the predetermined rotation range (crimping portion rotation range) at the time of opening rotation, not a rotation resistance that is larger than the rotation amount.

  Further, between the rotating shaft portion 4 and the coil spring 5 fitted to the rotating shaft portion 4, for example, as shown in the second embodiment shown in FIGS. (A metal cylinder interposed so as to be freely rotatable) may be interposed.

  In addition, the stopper portion 6 of the present embodiment may be an engaging recess in which the one end portion 5A of the coil spring 5 that moves relatively is engaged with the concave and convex portions, but is configured by a butting portion 6A that is simply abutting and locking. When the rotation of the coil spring 5 is further prevented from rotating, the rotation shaft portion 4 resists sliding resistance (rotation resistance) caused by the crimping of the coil spring 5 to the rotation shaft portion 4. Then, it is configured to rotate.

  More specifically, the stopper portion 6 is provided on the first member 1 together with the bearing portion 3 in a non-rotating state, but in this embodiment, the stopper portion forming member 6B can be pivotally supported by the pivot shaft portion 4 in a pivotally supported state. The stopper forming member 6B is provided with a notch, and a pair of the abutting portions 6A are provided at opposite positions in the rotation direction, and the stopper portion 6 is opposed to the rotation direction. The one end portion 5A of the coil spring 5 is relatively moved between the two stopper portions 6 (butting portions 6A), and the one end portion 5A of the coil spring 5 is relatively moved between the butting portions 6A. When the stopper 6 is abutted and locked and further rotated, a rotational resistance is generated by the pressure bonding of the coil spring 5. In other words, the rotation resistance is configured so that a strong brake is generated when rotating beyond the locked position in the rotation direction so that the crimping portion resistance rotation range is generated before and after the free rotation range. The mechanism C is configured.

  Specifically, in this embodiment, the superposition part 2 is provided in a superposed state with respect to the main body part 1, and the superposition part 2 superposed on the main body part 1 is swung up and down from the superposition closed state to the rotational open position. It is configured to open and rotate, and the overlapping portion 2 is opened and rotated by 90 degrees or more with respect to the main body 1 and the weight of the member that opens and rotates is added to the main body portion 1 in the range before the rotation opening position. In the front range of the closing position where the portion 2 is forced to close by its own weight, the one end portion 5A of the coil spring 5 abuts against the stopper portion 6 and is prevented from rotating, thereby preventing the coil spring 5 from rotating. The rotation shaft portion 4 is rotated as it is, so that the rotation resistance due to the pressure bonding of the coil spring 5 is generated, and the moment of reaching the open rotation position and the close position is reduced. Set the position That.

  More specifically, in this embodiment, a cam engagement portion 8 and a cam portion 9 that are relatively rotated and engage with each other at a predetermined rotation position are provided opposite to the rotation shaft portion 4. Provided with a click engagement mechanism K in which the rotational position is maintained by the concave-convex engagement between the portion 8 and the cam portion 9, and the cam engagement portion 8 is provided integrally and the cam portion 9 is slidably supported. A cam engagement biasing spring 11 is provided on the moving shaft portion 4, and the rotation shaft portion of the click engagement mechanism K that biases the cam portion 9 to the cam engagement portion 8 by this spring biasing is rotated. A coil spring 5 is fitted on the extension 4 </ b> A of the rotating shaft 4.

  That is, in this embodiment, the click engagement mechanism K is provided in the bearing portion 3 that bears the rotating shaft portion 4. In other words, the crimping portion 5, that is, the coil spring 5 may be provided on the rotating shaft portion 4 of the click engagement mechanism K, and the stopper portion 6 may be provided on the bearing portion 3, but in this embodiment, the stopper portion 6 is the first member 1. Are separately provided in a non-rotating state so as to be juxtaposed with the bearing portion 3.

  More specifically, the bearing portion 3 includes a cam portion 9 provided with a bearing hole in a rotating state in the case body 10 inserted and fixed in a non-rotating state in the mounting hole of the first member 1. It is provided so as to be slidable along the rotating shaft portion 4 that passes through.

  The cam portion 9 that supports the rotation shaft portion 4 through the insertion shaft is urged by a cam engagement urging spring 11 that is also housed in the case body 10, and is provided at the tip of the rotation shaft portion 4. The engaging portion 8 is configured to engage with the concave and convex portions at a predetermined rotational position. The member provided with the cam engaging portion 8 is configured to be prevented from rotating by the second member 2.

  In this embodiment, the concave / convex engagement position between the cam engagement portion 8 and the cam portion 9 is a fully open position (for example, a 170-degree rotation open position), and a position that is 180 degrees out of phase, for example, 10 degrees past the closed position. The engagement is clicked at the fully open position, and the close bias is generated in the middle of the uneven engagement at the closed position.

  In this embodiment, the engagement biasing by the cam engagement biasing spring always causes a rotation resistance at a position other than the concave / convex engagement position. However, with this alone, the weight of the overlapping portion 2 when rotating is rotated. In the rotation range after 90 degrees applied in the direction, if this weight is too large, the rotation speed may exceed the allowable range. Therefore, both before the fully open position and before the closed position, a new one is newly added. A large rotational resistance is generated, and the rotational resistance is generated by the coil spring 5 which is a weak rotational resistance before the closed position than before the fully opened position.

  More specifically, in the present embodiment, the left and right main hinge device provided with the click engagement mechanism K is provided with the rotation resistance mechanism C, but the rotation shaft portion 4 of the click engagement mechanism K is extended. As shown, the extension 4A of the rotating shaft 4 protrudes from the case body 10, the coil spring 5 is wound around the extension 4A, and is elastically attached in a tightly wound state so as to rotate integrally. Only the coil spring 5 is provided on the rotation shaft portion 4 so that a substantially constant rotation resistance (brake) is always generated in a predetermined rotation range in a predetermined direction.

  Then, a stopper portion forming member 6B having an abutting portion 6A is provided so as to be adjacent to the case body 10, and the pair of the abutting portions 6A is designed and set at a predetermined phase position to set a range in which the rotational resistance by the coil spring 5 is generated. ing.

  When the winding direction of the coil spring 5 is set and the one end portion 5A is locked to the one abutting portion 6A in the opening rotation direction to generate a rotation resistance, the coil spring 5 is wound and tightened strongly. When the rotating shaft 4 rotates in the closing direction on the contrary, the coil spring 5 is deformed so as to be unwound and the pressure-bonding degree of the coil spring 5 is weakened, so that a slightly weaker brake is applied.

  Furthermore, a torsion spring is provided on this hinge device, or a torsion spring is provided on the other auxiliary hinge device to cause an opening rotation bias that always helps opening, a lock release button, or a clutch cam for unlocking. You may comprise so that engagement may be provided and an automatic open | release rotation may be carried out. In other words, a strong torsion spring is provided that is energized to open and rotate by a torsion spring to facilitate or automatically rotate, and when the release button is pressed, the lock is released and the torsion spring automatically rotates and opens. You may comprise. In this case, the rotation resistance mechanism C of the present invention is provided so that a particularly large brake is generated in the range before the fully open position. That is, for example, the coil spring 5 may be further enlarged by increasing the tightening force, increasing the crimping area, or increasing the diameter of the rotating shaft 4. Then, as described above, when the coil spring 5 is set in the winding direction and is locked to the stopper portion 6 when the coil spring 5 is turned and further rotated, the coil spring 5 is wound and deformed so that a stronger brake is generated. In the case of closing, this automatically becomes a weaker brake. In this way, when the rotation is urged by the torsion spring, the present invention is particularly designed to be able to obtain a strong brake with a simple structure, and conversely, the brake is applied even when the closure is turned. Since the brake can be set to be weaker than this, since such a setting is particularly effective, the invention becomes more effective.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
