Description

  The present invention relates to an electronic apparatus capable of causing a second housing provided with a display unit to perform a cycloid operation on a first housing provided with an operation unit.

  In small electronic devices such as notebook PCs, PDAs, Zaurus (trademark), and mobile phones, a first housing with an operation unit such as a keyboard provided on the upper surface and a display unit such as an LCD provided on the lower surface A closed state in which the first casing and the second casing overlap with each other and cover the upper surface of the first casing with the second casing; It is known that two housings are rotated in the vertical direction with respect to the first housing to create an open state in which the upper surface of the first housing and the lower surface of the second housing are exposed.

  In recent years, in the electronic devices described above, in addition to their original functions, various functions such as functions using communication lines such as the Internet, digital camera functions, recording / playback functions, TV reception functions, game functions, etc. Things with are on the market. For this reason, for example, when displaying a moving image of a television especially on the display unit, the second housing is used in a horizontally long state rather than being used in a vertically long state with respect to the first housing. Is better.

For this reason, some mobile phones have a cycloid function that can be rotated from a vertically long state to a horizontally long state with the second housing opened with respect to the first housing (for example, Patent Documents 1 and 2).

At the other end inserted, an elastic means (disc spring 51) that is a component of the control means 5 that presses the base member 2 against the mounting member 3 to generate a friction torque between the base member 2 and the mounting member 3. ) Is provided and this end is caulked. Accordingly, the first shaft 41 is slidably engaged without coming out of the first guide long hole 21.

  The first shaft 41 and the second shaft 42 are engaged with the first guide long hole 21 and the second guide long hole 22 without coming out of the first shaft 41 and the second shaft 42, respectively. The housing 12 slides in the vertical direction while rotating in the horizontal direction between the horizontally long state and the vertically long state. In this neutral state, the first shaft 41 is positioned at the upper end portion 21 b of the first guide long hole 21 and the second shaft 42 is positioned at the substantially top portion 22 c of the substantially inverted U shape of the second guide long hole 22. As described above, the first guide long hole 21 and the second guide long hole 22 are formed, and the first shaft 41 and the second shaft 42 are attached.

  That is, the shape of the first guide long hole 21 and the second guide long hole 22 and the mounting positions of the first shaft 41 and the second shaft 42 are such that the second housing 12 is in a horizontally long state with respect to the first housing 11. Sometimes (see FIGS. 1B and 2A), the first shaft 41 is positioned at the lower end of the first guide slot 21 and the second shaft 42 is one of the second guide slots 22. When the second casing 12 is slid in the vertical direction while rotating with respect to the first casing 11 (supporting means 13) from the horizontally long state, the first shaft is positioned at the end portion 22a of the first casing 11a (see FIG. 4). 41 slides in the direction of the upper end portion 21b of the first guide long hole 21, and the second shaft 42 slides toward a substantially central portion of the second guide long hole 22 (approximately the top portion 22c of the central portion of the substantially inverted U shape). In the intermediate state (neutral state) (FIG. 1 (c) and FIG. (See (b).) The first shaft 41 is positioned at the upper end portion 21 b of the first guide long hole 21, and the second shaft 42 is positioned at the substantially top portion 22 c of the substantially inverted U shape of the second guide long hole 22. The first shaft 41 is positioned at the lower end portion 21a of the first guide long hole 21 and the second shaft 42 is connected to the other end portion 22b of the second guide long hole 22 (see FIGS. 3 and 4). It is positioned (see FIG. 3) and is configured to be in a vertically long state (see FIG. 1 (d) and FIG. 2 (c)). In this vertically long state, the second housing 12 has one side portion (left side portion in the illustrated example) of the first housing 11 and one side portion (left side in the illustrated example) of the second housing 12 in the vertically long state. Are preferably arranged so that the lower end of the vertically long second casing 12 is positioned near the upper end of the first casing 11. . In the intermediate state, the first shaft 41 is positioned at the upper end portion 21b of the first guide long hole 21, and the second shaft 42 is substantially at the top portion 22c of the substantially inverted U shape of the second guide long hole 22. However, the present invention is not limited to this. Further, the position of the second housing 12 with respect to the support means 13 in the vertically long state is not particularly limited, and may be positioned at a desired position.

  The control means 5 is not particularly limited as long as the friction torque can be generated between the base member 2 and the mounting member 3 by pressing the base member 2 against the mounting member 3. Examples of the elastic means include a disc spring, a spring washer, a compression spring, and the like. For example, a disc spring 51 is used. The number of disc springs 51 is not particularly limited, and is one in the illustrated example. The disc spring 51 is attached to the end of the first shaft 41 protruding from the first guide long hole 21 via washers 57 and 58. When the second casing 12 is slid while rotating the second casing 12 between the horizontally long state and the vertically long state with respect to the support means 13 to stop the movement, the second casing 12 is in the first position at the position. It is preferable that the friction torque held with respect to the housing 11 (supporting means 13) is generated between the base member 2 and the mounting member 3, that is, has elasticity that creates a free stop state. The control means 5 includes the disc spring 51, which is the elastic means, the first shaft 41, and the click friction plate 61 in contact with the base member 2. In this embodiment, the control means 5 is a friction generating means. That is.

  Moreover, you may provide the click stop means 6 which hold | maintains the 2nd housing | casing 12 in the position of a horizontally long state and a vertically long state with respect to the 1st housing | casing 11. FIG. The click stop means 6 is not particularly limited. For example, the click friction plate 61 provided on the outer periphery of the first shaft 41 between the base member 2 and the mounting member 3, the click friction plate 61, and the base member 2 Either one of them, for example, an engagement convex portion 62 provided on the click friction plate 61, engages with the engagement convex portion 62 in the vertically long state or the horizontally long state, and is either the base member 2 or the click friction plate 61. On the other hand, for example, an engagement recess 63 provided in the base member 2 is provided.

  The click friction plate 61 is formed in a disk shape having a diameter substantially the same as the diameter of the circular portion of the mounting member 3, for example. The click friction plate 61 is provided with an insertion hole 61a through which the first shaft 41 is inserted. Two opposing portions of the insertion hole 61a are further provided with cutout portions 61b cutout radially outward. The click friction plate 61 outside the notches 61b is provided with arcuate through holes 61c.

  The engaging protrusions 62 are, for example, at two positions between the notch 61b and the through hole 61c on the lower surface (the surface on the base member 2 side) of the click friction plate 61 and spaced by 180 degrees in the circumferential direction. Protrusively provided. The engaging recesses 63 that engage with the engaging protrusions 62 are provided at two locations near the lower end of the first guide long hole 21 of the base member 2, and the first guide is in the horizontally long state and the vertically long state. When the first shaft 41 is positioned at the lower end 21 a of the long hole 21, the engaging convex part 62 and the engaging concave part 63 are engaged.

  In addition, two slide guide portions 66 protrude from the lower surface of the outer side of the insertion hole 61a of the click friction plate 61 at intervals of 180 degrees in the circumferential direction, for example (see FIG. 5). These slide guide portions 66 are slidably engaged with plate guide long holes 67 provided in the base member 2. The plate guide long holes 67 are formed in the vicinity of both side portions of the first guide long holes 21 of the base member 2 so as to extend substantially parallel to the first guide long holes 21. The slide guide portions 66 are formed in the plate guide long holes 67. When the first shaft 41 is slidably engaged along the first guide long hole 21, the click friction plate 61 does not rotate with respect to the first shaft 41. It slides with 41.

  Next, the operation of the first embodiment according to the present invention will be described.

  In a state where the electronic device 10 is not used, the first housing 11, the second housing 12, and the support means 13 are normally in a closed state where they overlap each other (see FIG. 1A). At this time, friction torque is generated between the support means 13 and the second housing 12 by the elastic force of the disc spring 51 via the control means 5, and the engagement convex part 62 of the click friction plate 61 and the base member Since the two engaging recesses 63 are engaged, the first housing 11, the second housing 12, and the support means 13 are held in a closed state that almost completely overlap each other. In addition, in order to hold | maintain this closed state more reliably, you may make it provide a lock mechanism.

  When using the electronic device 10, for example, with the first housing 11 pressed by hand, the second housing 12 is hinged in the longitudinal direction (the short direction) in the direction of opening together with the support means 13. The second casing 12 is opened with respect to the first casing 11 by rotating through the device 17 (see FIG. 1B). As a result, the operation unit 14 such as a keyboard unit provided on the upper surface of the first housing 11 is exposed so as to be operable, and the display unit 15 is exposed so as to be visible in the horizontally long state. The electronic device 10 can be used. At this time, friction torque is generated between the support means 13 and the second housing 12 by the elastic force of the disc spring 51 via the control means 5, and the engagement convex part 62 of the click friction plate 61 and the base member Since the two engaging recesses 63 are engaged, the display unit 15 is held in the horizontally long state. In addition, in order to hold | maintain this closed state more reliably, you may make it provide a lock mechanism.

  When the display unit 15 is used in a vertically long shape, the second housing 12 is rotated counterclockwise with respect to the support means 13 with the second housing 12 opened with respect to the first housing 11. Then, the mounting member 3 slides in the vertical direction while rotating in the horizontal direction with respect to the base member 2, and the first shaft 41 slides from the lower end portion 21 a to the upper end portion 21 b of the first guide long hole 21. The second shaft 42 slides from the one end 22a of the second guide long hole 22 toward the top 22c.

  As shown in FIG. 2B, the first shaft 41 reaches the upper end portion 21b of the first guide long hole 21, and the second shaft 42 is an abbreviated U-shape of the second guide long hole 22. The top 22c is reached, and this state is a neutral state (intermediate state in the illustrated example). From this neutral state, the second housing 12 is further rotated counterclockwise with respect to the support means 13. Then, the first shaft 41 slides toward the lower end portion 21 a of the first guide long hole 21 and the second shaft 42 slides toward the other end portion 22 b of the second guide long hole 22. Then, the first shaft 41 slides to the lower end portion 21 a of the first guide long hole 21 and the second shaft 42 slides to the other end portion 22 b of the second guide long hole 22. In this way, the display unit 15 performs a cycloidal operation and becomes in a vertically long state (see FIGS. 1D and 2C). At this time, frictional torque is generated between the support means 13 and the second housing 12 due to the elastic force of the disc spring 51, and the engagement convex portion 62 of the click friction plate 61 and the engagement concave portion 63 of the base member 2 are provided. Are engaged with each other, the display unit 15 is held in the vertically long state. In addition, in order to hold | maintain this closed state more reliably, you may make it provide a lock mechanism.

  In order to return the display unit from the vertically long state to the horizontally long state, for example, the second housing 12 is rotated with respect to the support means 13 in the clockwise direction opposite to the above while the first housing 11 is fixed. Thus, the cycloid operation can be performed to return from the vertically long state to the horizontally long state. From this horizontally long state, for example, by rotating the second casing 12 in the longitudinal direction in the closing direction together with the support means 13 with the first casing 11 fixed, the first casing 11 is rotated. The second housing 12 and the support means 13 are in a closed state where they overlap each other.

  Further, when changing from the horizontally long state to the vertically long state and from the vertically long state to the horizontally long state, a friction torque is generated between the second housing 12 and the support means 13 by the elastic force of the disc spring 51, and the free stop is performed. Since it is in a state, when the second housing 12 is stopped at an arbitrary position with respect to the first housing 11, the second housing 12 is held in that state. That is, for example, when the second casing 12 is rotated with respect to the support means 13 so as to change from the horizontally long state to the vertically long state, if the operation is stopped in the middle of the second casing 12, And held at that position. Therefore, the second housing 12 can be stopped and held at an arbitrary position with respect to the first housing 11 (support means 13).

  Therefore, in the cycloid mechanism 1 and the electronic device 10 according to the present invention, since the friction torque is generated between the support means 13 and the second casing 12, the second casing 12 is positioned in the horizontally long state or the vertically long state. When stopping, the impact of the second housing 12 due to the stop can be reduced, and the impact such as failure or damage of the display unit 15 due to the impact can be prevented. . Further, the second housing 12 can be stopped at an arbitrary position during the cycloid operation with respect to the first housing 11, and since the structure is simple and the number of parts is small, the cost can be reduced and the thickness can be reduced. Furthermore, since the holding torque during operation when the second casing 12 is slid in the vertical direction while rotating with respect to the first casing 11 (support means 13) is determined by the elasticity of the disc spring 51, the disc spring 51 is By changing to a different elasticity, the holding torque during operation can be easily adjusted.

  Further, in a state other than the horizontally long state or the vertically long state, the engagement between the engaging convex portion 62 and the engaging concave portion 63 is released, and the engaging convex portion 62 is connected to the first guide long hole 21 on the base member 2 and the slide guide length. It rides between the holes and slides on the base member 2. When this state is changed to the horizontally long state or the vertically long state, the engagement convex portion 62 that has ridden on the base member 2 is engaged so as to fall into the engagement concave portion 63, so that a click feeling is generated. In this way, it is possible to easily grasp whether or not the second housing 12 is in the horizontally long state or the vertically long state by the click stopping means 6. Further, by changing the disc spring 51 to one having a different elasticity, it is possible to adjust the holding force for holding the horizontally long state or the vertically long state.

  Further, when the engagement convex portion 62 and the engagement concave portion 63 are disengaged and the engagement convex portion 62 rides on the base member 2, the engagement convex portion 62 is connected to the notch portion 61 b of the click friction plate 61. Since it is provided between the through-hole 61c, the back side of the engaging convex part 62 and its vicinity deform | transform and protrude. A through hole 35 is provided at a position of the mounting member 3 facing the protruding portion. In order for the protruding portion to enter the through hole 35, the base member 2 (actually the click friction plate 61), the mounting member 3, Since the friction acting between the click friction plate 61 and the mounting member 3 is in surface contact, the friction torque is generated between the click friction plate 61 and the mounting member 3 without deviation. The operation of the mounting member 3 with respect to the base member 2 can be performed satisfactorily. That is, when the engaging convex portion 62 rides on the base member 2 and the side opposite to the engaging convex portion 62 protrudes, if there is no through hole in the mounting member 3, the friction torque is increased between the protruding portion and the protruding portion. Since it occurs only in two places with the mounting member 3 in contact with the base member 2, when the mounting member 3 is rotated with respect to the base member 2, it may be rattled or the friction torque may be too high to rotate. is there.

  When the first cam portion 174, the second cam portion 175, the click friction plate 151, the click plate 152, and the compression spring 178 are in a horizontally long state or a vertically long state, the first housing 11 (support means 13) and the first The two housings 12 are preferably formed so as to be held. The first cam portion 174, the second cam portion 175, the click friction plate 151, the click plate 152, and the compression spring 178 are slid upward in the vertical direction while the mounting member 103 is rotated with respect to the base member 102. It is preferable that the mounting member 103 is formed so that a pressing force pressing upward in the vertical direction is applied. That is, when shifting from the horizontally long state to the vertically long state or from the vertically long state to the horizontally long state, the mounting member 103 slides upward in the vertical direction while rotating with respect to the base member 102. The casing 12 (attachment member 103) is formed to press upward in the vertical direction. Further, the first cam portion 174, the second cam portion 175, the click friction plate 151, the click plate 152, and the compression spring 178 are in a neutral state when the pressing force acting on the mounting member 103 is weakened as the neutral state is approached. It is preferable that the pressure is reduced.

  Next, the operation of the second embodiment will be described. Although members and instruction symbols not shown in FIGS. 6 to 8 are used, it should be understood together with those of the first embodiment.

  In a state where the electronic device 10 is not used, the first housing 11, the second housing 12, and the support means 13 are normally in a closed state where they overlap each other (see FIG. 1A). At this time, friction torque is generated between the click friction plate 151 and the click plate 152, and the engaging convex portion 162 and the engaging concave portion 163 are engaged. The housing 12 and the support means 13 are held in a closed state where they are almost completely overlapped with each other. In addition, in order to hold | maintain this closed state more reliably, you may make it provide a lock mechanism.

  When using the electronic device 10, for example, with the first housing 11 pressed by hand, the second housing 12 is hinged in the longitudinal direction (the short direction) in the direction of opening together with the support means 13. The second casing 12 is opened with respect to the first casing 11 by rotating through the device 17 (see FIG. 1B). As a result, the operation unit 14 such as a keyboard unit provided on the upper surface of the first housing 11 is exposed so as to be operable, and the display unit 15 is exposed so as to be visible in the horizontally long state. The electronic device 10 can be used. At this time, friction torque is generated between the click friction plate 151 and the click plate 152 via the control means 105, and the engaging convex portion 162 and the engaging concave portion 163 are engaged. 15 is held in a horizontally long state. In addition, in order to hold | maintain this closed state more reliably, you may make it provide a lock mechanism.

  When the display unit 15 is used in a vertically long shape, the second housing 12 is rotated counterclockwise with respect to the support means 13 with the second housing 12 opened with respect to the first housing 11. Then, the attachment member 103 rotates with respect to the base member 102 while sliding in the vertical direction, and the first shaft 141 slides from the lower end portion 121a of the first guide long hole 121 toward the upper end portion 121b and the second shaft. 142 slides from one end 122a of the second guide slot 122 toward the top 122c. Then, as shown in FIG. 6B, the first shaft 141 reaches the upper end 121b of the first guide long hole 121 and the second shaft 142 reaches the substantially top portion 122c of the second guide long hole 122. The state is a neutral state (intermediate state in the illustrated example).

  As described above, when the second housing 12 is changed from the horizontally long state to the neutral state by the cycloid operation, the slider body together with the first shaft 141 is moved when the first shaft 141 slides the first guide long hole 121 to the upper end portion 121b. 181 slides relative to the base member 102, and the first cam body 172 acts to push the second cam body 173 upward by the elastic force of the elastic means 177 in the slider body 181. When the body 12 is rotated and slid upward in the vertical direction, the second housing 12 can be easily operated in a cycloid manner. That is, from the horizontally long state to the neutral state, the second casing 12 must be rotated counterclockwise with respect to the first casing 11, and the electronic device 10 is a notebook personal computer and the display unit 15 is Since the weight of the second housing 12 becomes heavier when the size is larger than that of the mobile phone, the pressing force of the cycloid operation urging means 107 acts on the second housing 12 without feeling the weight. The second housing 12 can be operated in a cycloid manner.

  Further, as the neutral state is approached, the first cam portion 174 approaches the valley of the second cam portion 175, the elasticity of the compression spring 178 is weakened, the pressing force acting on the mounting member 103 is weakened, and the neutral state Sometimes, the first cam portion 174 reaches the valley of the second cam portion 175 and its pressing force is weakened, so that it does not stop suddenly when it becomes neutral.

  From the neutral state, the second housing 12 is rotated counterclockwise with respect to the support means 13. Then, the first shaft 141 slides toward the lower end portion 121 a of the first guide long hole 121 and the second shaft 142 slides toward the other end portion 122 b of the second guide long hole 122. Then, the first shaft 141 slides to the lower end portion 121a of the first guide long hole 121 and the second shaft 142 slides to the other end portion 122b of the second guide long hole 122 (see FIG. 6C). The display unit 15 is in the vertically long state. At this time, friction torque is generated between the click friction plate 151 and the click plate 152, and the engaging convex portion 162 and the engaging concave portion 163 are engaged, so that the display portion 15 is held in the vertically long state. Is done. In addition, in order to hold | maintain this closed state more reliably, you may make it provide a lock mechanism.

  As described above, when the second casing 12 is moved downward with respect to the support means 13 from the neutral state to the vertically long state, the compression spring 178 generates torque when contracting against the elasticity. The second housing 12 does not vigorously stop when it hits the first housing 11 (support means 13) or the like or is in a vertically long state.

  In order to return from the vertically long state to the horizontally long state, for example, the first housing 11 is fixed and the second housing 12 is rotated with respect to the support means 13 in the clockwise direction opposite to the above. The state can be returned to the landscape state. From this horizontally long state, the first casing 11, the second casing 12, and the support means 13 overlap each other by rotating the second casing 12 together with the support means 13 in the longitudinal direction in the closing direction via the hinge device 17. Closed state.

  Therefore, in the electronic device 10 according to the present invention, since the friction torque is generated between the support means 13 and the second housing 12 by the control means 105 that is the friction generating means, the second housing 12 is placed in the horizontally long state. Alternatively, when stopping at the position of the vertically long state, the impact of the second housing 12 due to the stop can be reduced, and the impact such as failure or damage of the display unit 15 occurs due to the impact. Can be prevented. In addition, when the cycloid operation urging means 107 is used, a pressing force is applied when the second housing 12 is lifted upward with respect to the first housing 11, so that the first weight is not felt. The two housings 12 can be operated in a cycloid manner. Further, the torque during the operation when the second housing 12 is operated in a cycloidal manner with respect to the support means 13 includes the click friction plate 151, the click plate 152, the first cam body 172, the second cam body 173, and the compression spring 178. Therefore, by changing the click friction plate 151, the click plate 152, the first cam body 172, the second cam body 173, and the compression spring 178 to different ones, it is possible to easily adjust the torque during the cycloid operation.

  Further, when the state is other than the horizontally long state or the vertically long state, the engagement between the engagement convex part 162 and the engagement concave part 163 is released, and the engagement convex part 162 becomes the first guide long hole 121 and the second guide on the base member 102. It climbs between the long holes 122 and slides on the base member 102. When this state is changed to the horizontally long state or the vertically long state, the engaging convex portion 162 riding on the base member 102 is engaged so as to fall into the engaging concave portion 163, so that a click feeling by the click stopping means 106 occurs. Therefore, it can be easily grasped whether or not the second casing is in the horizontally long position or vertically long position. Further, by changing the click friction plate 151 and the click plate 152 to different ones, the holding force for holding the second housing in the horizontally long state or the vertically long state can be adjusted.

  Further, in any of the first and second embodiments described above, as a control means for controlling the cycloid operation of the second housing, the shock at the end of the cycloid operation of the bracket is applied by a buffer means using only a compression spring or other elastic means. It can be configured to control by absorbing. Further, the support means may be a simple support member instead of the housing.

  As described in detail above, the present invention includes the control means for generating the friction torque between the base member and the mounting member, so that the second housing is stopped at the position of the horizontally long state or the vertically long state with respect to the support means. The impact of the second housing can be reduced, and it is possible to prevent the display unit from malfunctioning or being damaged due to the impact. It is the best one.
