Definitions
- the present invention relates to a rotation support mechanism used for an opening and closing part of a mobile terminal such as a mobile phone and an electronic organizer. More specifically, the present invention relates to a rotation support mechanism and a portable terminal having an efficient opening function that allows the cover to be rotated in a planar direction with one touch when opening and closing the main body and the cover that are vertically stacked.
- a mobile phone that incorporates this kind of rotation support mechanism and opens and closes a cover is configured such that the main body and the cover are folded in two and superimposed on each other so that the rotation axis of the rotation support portion is used as an opening and closing support point.
- a folding type rotation support mechanism cover-opening / closing mechanism that opens the main body and the cover in the overlapping direction is known (for example, see Patent Document 1).
- Patent Document 1 JP-A-2003-28138.
- the force holding the mobile phone in one hand also overlaps with one hand! /
- the upper cover can be pushed sideways to displace the main unit and the cover up and down stepwise. Therefore, it becomes easy to grasp the cover, and the rotation operation of the cover thereafter becomes easy.
- the rotation support mechanism that opens and closes the cover in the planar direction as it is superimposed becomes bulky because the rotation axis is perpendicular to the cover opening and closing structure. It was getting harder. Furthermore, when opening and closing the main body and the cover, it is necessary to devise the amount and direction of rotation of the cover so that the wiring connecting them does not twist in the rotation direction. As a result, there was a limit to thinning.
- the rotating shaft support 273 As a connecting portion is used. It is easy for excessive force such as torsional force to be applied. Therefore, the rotating shaft support 273 needs a stable structure without causing wobble (rattle).
- the tip 274 of the cover 272 is farthest from the rotating shaft support 273, so that there is a gap even if there is a slight gap. There was a risk of wobbling in the direction.
- the present invention provides a rotation support function for automatically rotating the cover to the open position, so that the user can open the cover with one touch with one hand, and the force is convenient to carry. It is an object of the present invention to provide a rotation support mechanism and a mobile terminal that can achieve a low profile and eliminate a wobble of a cover to enhance a sense of stability.
- the present invention is directed to a rotation support mechanism that closes the main body and the cover and closes the cover, rotates the cover in the planar direction while keeping the cover superimposed, and stops the cover from rotating to the open position rotated 180 degrees.
- An eccentric cam having an open position corresponding portion, and a pressing direction set in the same direction as the direction connecting both positions of the closed position corresponding portion and the open position corresponding portion which are different from each other by 180 degrees through the axis of the eccentric cam.
- Pressing means for lowering the pressing load on the eccentric cam and stopping the rotation of the eccentric cam by increasing the rotation restricting force with respect to the eccentric cam when corresponding to the open position corresponding portion It is characterized in that it is attached to the main body and the other is attached to the cover to rotate and support the cover.
- the eccentric cam rotates eccentrically in a plane direction, and generates a rotational force on the eccentric cams having different eccentric amounts by the pressing force of the pressing means for pressing the cam surface of the eccentric cam.
- the amount of eccentricity varies depending on the eccentric rotation position of the eccentric cam, and the pressing load varies in proportion to the amount of eccentricity. For this reason, at the maximum eccentric rotation position where the amount of eccentricity is large, a high pressing load is applied, a force for moving to the minimum eccentric rotation position with a low pressing load acts, and the pressing means generates a rotating force on the eccentric cam.
- the eccentric cam can use an outer peripheral surface as a cam surface, and an upper and lower surface along the outer peripheral surface.
- a groove or a ridge for guiding the pressing means can be formed on at least one of them, and these grooves and ridges can be used for the cam surface.
- the pressing means can be composed of, for example, a panel, and the pressing force of the panel can correspond to the pressing of the cam surface of the eccentric cam all the time. For this reason, the pressing force differs depending on the position corresponding to the eccentric cam, and the eccentric cam rotates in a different direction depending on the contact angle with the cam surface, and can cause the eccentric cam to rotate left or right.
- the cover can be automatically rotated from the closed position to the open position by using the pressing force of the pressing means as the rotational force in the cover opening direction.
- an engagement configuration may be adopted in which both can be engaged and disengaged at one point in the rotation direction.
- the cover can be accurately positioned at one point of the rotation stop position corresponding to the unevenness.
- an eccentric cam that rotates in a plane direction suitable for thinning is adopted, and a low-bulk pressing means suitable for thinning that presses the cam surface of the eccentric cam in the plane direction is combined. It is composed. For this reason, it is not bulky in the vertical direction, and the rotation support mechanism can be downsized, and the portable terminal can be provided thin.
- the restricting means may be provided with, for example, an interlocking piece as a rotation position restricting member that rotates in conjunction with the rotation of the eccentric cam, and if the rotation of the interlocking piece is restricted at a predetermined position, the eccentricity may be reduced. Excessive rotation of the cam beyond a predetermined position can be restricted. [0022] Therefore, for example, when the cover is rotated 180 degrees to the left and the cover and the main body are opened in a serial state in which the cover and the main body are aligned vertically, the further left rotation is regulated and the open state is maintained. For this reason, an excessive rotation operation that attempts to exceed the rotation limit position of the cover can be restricted.
- An eccentric cam having another configuration according to the present invention has a closed position corresponding portion corresponding to the pressing means at one point of the maximum eccentric rotation position on the eccentrically rotating cam surface, and at one point of the minimum eccentric rotation position.
- An opening position corresponding portion corresponding to the pressing means is provided.
- the pressing means for pressing the cam surface of the eccentric cam from beginning to end corresponds to the open position corresponding portion. It is possible to accurately position the opening / closing positions having different directions of 180 degrees corresponding to the irregularities at one point with the closing position corresponding portion, and to accurately stop the rotation of the cover.
- the pressing means includes a position corresponding to both the closed position corresponding portion and the open position corresponding portion which are different in the 180-degree direction and whose opening / closing positions are defined through the axis of the eccentric cam.
- An elastic member having a pressing direction set in the same direction as a direction connecting the elastic member, and a follower member which advances and retreats in the pressing direction and follows the cam surface of the eccentric cam based on receiving the pressing force of the elastic member. Can be provided.
- the elastic member can be configured using an elastic body that applies a pressing force in a pressing direction, for example, a panel such as a coil panel or a plate panel.
- the following member may be any contact member that smoothly contacts the cam surface. For example, force while rotating according to the rotation of the eccentric cam
- the pressing roller can be configured to follow the memory surface.
- the pressing means can be easily configured by combining the elastic member and the following member.
- the pressing means having another configuration according to the present invention is characterized in that the opening / closing position is defined through the axis of the eccentric cam.
- a pressing panel having a pressing direction set in the same direction as the direction in which the pressing panel is connected, a pressing piece which advances and retreats in the pressing direction by receiving a pressing force of the pressing panel, and which is rotatably supported by the pressing piece and is rotatably supported by the pressing panel.
- a pressing roller may be configured to receive a pressing force and to press the cam surface of the eccentric cam in the pressing direction integrally with the pressing piece.
- the pressing panel may be constructed by providing a plurality of springs provided by using a coil panel, for example, and by providing only one spring.
- a uniform pressing force can be applied to the eccentric cam via the pressing roller with the same lateral force. Therefore, a well-balanced and stable pressing operation can be given toward the center of the eccentric cam, and the operation when the eccentric cam rotates by receiving the pressing force is stabilized.
- the pressing piece is pressed using the principle of leverage, and a pressing roller is disposed at an intermediate position between the pressing pieces so as to face the center of the eccentric cam. It is also possible to adopt a configuration in which the pressing roller stably presses.
- the pressing panel can also be disposed on both sides or one side of the eccentric cam, and can be set in a direction to pull the pressing roller integrated with the pressing piece toward the eccentric cam.
- the stroke of the pressing panel constituting the pressing means can be arranged along the side surface of the eccentric cam parallel to the pressing direction of the eccentric cam. Therefore, the pressing panel and the eccentric cam can be efficiently arranged in a small space in the pressing direction, and the rotation support mechanism can be downsized.
- the pressing roller follows and contacts the cam surface while rotating, a smooth response operation can be obtained. Further, in addition to the pressing roller, a non-rotating, slippery convex portion may be provided.
- the pressing means By configuring the pressing means in this way, it is possible to make the pressing panel, the pressing piece, and the pressing roller each have a low-bulk pressing structure in which each of the pressing panel, the pressing piece, and the pressing roller is operated in a plane direction, so that the pressing means can be made thin.
- the restricting means of another configuration of the present invention includes a rotating disk that rotates leftward or rightward in a planar direction, an interlocking piece that rotates in the same rotational direction by receiving the rotating force of the rotating disk, A position restricting portion for restricting an excessive rotation of the interlocking piece, in which the moving piece rotates leftward or rightward along with the rotating disk, and the interlocking piece tries to rotate beyond the open position corresponding portion of the eccentric cam. And can be configured.
- the position of the interlocking piece can be regulated to a predetermined position, so that a planar position regulating structure can be realized.
- the mobile terminal can be made thinner.
- both ends of the interlocking piece can be effectively used as a position regulating surface, and the left-rotating open position corresponding part and the right-hand part can be used. It is possible to accurately set the position regulation at the portion corresponding to the open position of rotation.
- the cover is prevented from wobbling in the overlapping direction on an opposing surface near a shaft supporting portion that connects and supports both the overlapping directions in which the main body and the cover oppose each other.
- the rotation supporting mechanism can be configured to include the steady rest portion.
- the steady rest portion is for completely eliminating the unstable movement of the front end portion of the cover in the overlapping direction around the shaft supporting portion that connects and supports the main body and the cover. It is. Since the cause of the wobble is the generation of a gap generated in the overlapping direction, for example, a protrusion corresponding to the gap generated between the facing surfaces of the main body and the cover in the overlapping direction is formed by projecting, for example, a local portion. If the projections are made to contact with each other, there is no room for the projections to wobble, and it is possible to eliminate the wobbling at the cover tip. In addition, besides the convex portions, a contact-response shape suitable for steadying may be formed between the overlapping surfaces, and a member for absorbing steadying may be interposed.
- the steady rest portion exists between the main body and the cover, the steady rest function works even when the cover is closed or opened, thereby preventing the cover from wobbling.
- the cover is rotated 180 degrees in the plane direction with the main body and the cover superimposed on each other and opened, a pressing force in the superimposed direction is applied to the support of the cover during and after the opening operation.
- the steady rest part eliminates the unstable wobble of the cover, and a stable opening / closing operation feel can be obtained.
- the steady rest is formed on the opposing surface near the pivot between the main body and the cover, the steady rest is covered with the main body and the cover even when the cover is rotated by 180 degrees. There is no state. Therefore, there is no danger of damage due to direct external force from the outside, and there is an advantage that the aesthetic appearance is not impaired because it is not visible from the outside.
- the present invention there is no room for generating wobble between the opposing surfaces by only partially contacting the respective bosses projecting in an abutting state between the opposing surfaces of the main body and the cover in the overlapping direction.
- the wobbling of the cover can be completely eliminated. Therefore, it is possible to easily construct a structure for preventing the cover from wobbling simply by providing the boss portions on the opposing surfaces facing each other. For example, if the boss is formed so as to protrude so as to make point contact, the contact resistance is reduced, and a smooth cover opening / closing operation can be ensured.
- a steady rest portion having another configuration according to the present invention has a plurality of abutting portions of the boss portion, and the position of the boss portion at each of the abutting portions is determined by determining the axial center portion of the eccentric cam. It is possible to configure the apparatus such that the radial distances determined at the center are different from each other and are not present on concentric circles but are scattered at positions.
- the contact stability between the main body and the cover is enhanced by arranging a plurality of abutting portions of the opposing boss portions.
- the boss portions of the respective abutting portions are not located on the concentric circles by dispersing the positions of the boss portions of the respective abutting portions at different positions that do not exist on the concentric circles. Therefore, even if the cover is rotated, since there is no other boss in the direction of rotation, interference between the bosses can be avoided, and smooth rotation of the cover is ensured.
- the length of the main body and the cover around the axis of the eccentric cam facing each other in the closed position where the main body and the cover are overlapped with each other are oriented in the 180-degree direction.
- the boss portion may be formed at a position on the base end side between the distal end side and the base end side which are different in length. According to the present invention, when the cover is closed, the boss portion is opposed to the base end portion side, so that the distal end portion of the cover is overlapped on the pivot support point in accordance with the projecting amount of the boss portion. It can be tilted or parallel to the direction.
- a boss is provided not only on the base end side of the cover centering on the pivot portion, but also on the distal end side, so that the boss can be stably held even when the cover is closed or open.
- the wobble of the cover can be eliminated by making contact.
- the pressing means of another configuration of the present invention is characterized in that a base is mounted on the upper surface of the main body, and a pressing piece urged by a pressing panel on the base is pressed toward the eccentric cam so that the sliding guide can freely move forward and backward.
- An inclined guide portion in which the two contact guide portions are inclined and opposed to each other is provided on both sides in the slide width direction.
- the slide guide structure of the pressing piece is provided in the inclined guide portion in which the contact guide portions of the pressing piece and the base are inclined and opposed to each other. For this reason, a contact guide action is obtained in the vertical directions and the left and right stereoscopic directions, and a stable slide guide action with less contact fluctuation is obtained as compared with a contact parallel to the slide width direction. Furthermore, since the inclined guide portions are provided on both sides in the slide width direction, a uniform slide guide action can be obtained on both sides.
- the pressing means of another configuration of the present invention includes the inclined guide portion on both sides in the slide width direction, a shaft portion disposed at the center of the pressing piece in the slide width direction, and It can be configured to include a slide guide groove formed on the base corresponding to the concave portion along the slide direction and a central slide guide portion.
- the shaft portion may be a pressing roller rotatably supported at the center in the width direction of the pressing piece toward the eccentric cam, or a shaft portion of the pressing roller.
- the pressing piece can be slid in the pressing direction by a total of three sliding guide functions of the center sliding guide section in addition to the inclined guide sections on both sides.
- the contact part between the pressing piece and the base is worn out for a long period of time, since it is in contact with the inclined direction, it does not wobble during the pressing operation and maintains a stable sliding action. You can do it.
- the wobble restricts the wobble in the overlapping direction, so that the cover can be used as a mobile terminal with no wobble and a sense of stability. it can.
- the portable terminal can be applied to a monophone device such as a portable telephone, an electronic organizer, and the like, which includes a main body and a cover that are supported by a rotation support mechanism and that are opened and closed.
- a monophone device such as a portable telephone, an electronic organizer, and the like, which includes a main body and a cover that are supported by a rotation support mechanism and that are opened and closed.
- the operation of opening the cover, which is mounted on the main body in a plane, in the plane direction is automated, not manually, and the use performance in which the user can open the cover with one hand is enhanced.
