Description

[Technical field]

[0001] The present invention relates to a hinge device that rotatably connects a first housing and a second housing, and to an electronic device in which the first housing and the second housing are rotatably connected by the hinge device. [Background technology]

[0002] In electronic devices such as notebook PCs, a configuration is used in which a main body housing and a display housing are connected by a hinge device so that they can rotate relative to each other. The main body housing is usually used while placed on a desk, and the position of the main body housing does not change even if the display housing is rotated (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-036805 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent electronic devices, the amount of heat generated is increasing with the increasing performance of the CPU and other components, and more efficient cooling is required. Fans are used to cool electronic devices, and intake holes are often provided on the underside of the main body housing. However, the gap between the main body housing and the surface on which it is placed, such as a desk, is narrow, resulting in high intake resistance. Legs made of rubber or the like are provided on the underside of the main body housing, and although the intake resistance can be reduced by increasing the height of these legs, large legs are not desirable from a design perspective.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a hinge device and electronic device that can achieve a suitable design in the closed state when the first housing and the second housing are stacked, and can ensure a gap of an appropriate width between them and the placement surface in the open state. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, a hinge device according to a first aspect of the present invention is a hinge device that rotatably connects a first housing and a second housing, each of which has a flat shape, and includes a first shaft that extends in a first direction along a connecting edge between the first housing and the second housing and is rotatably supported on the first housing near the connecting edge with the second housing, a second shaft that extends in the first direction and is fixed to the second housing near the connecting edge with the first housing, a crank that non-rotatably connects the first shaft and the second shaft, a slider that is provided on the first housing so as to be slidable in a second direction perpendicular to the first direction, and a link that supports the slider in the first direction and the second shaft, and wherein as the first housing and the second housing rotate from a closed state in which they are stacked to an open state, the link protrudes from a surface that does not face the second housing in the closed state.

[0007] Moreover, an electronic device according to a second aspect of the present invention is an electronic device in which a first housing and a second housing, each of which has a flat shape, are rotatably connected by a hinge device, the hinge device having a first shaft extending in a first direction along a connecting edge between the first housing and the second housing and rotatably supported on the first housing near the connecting edge with the second housing, a second shaft extending in the first direction and fixed to the second housing near the connecting edge with the first housing, a crank connecting the first shaft and the second shaft non-rotatably, a slider provided on the first housing so as to be slidable in a second direction perpendicular to the first direction, and a link supporting the slider in the first direction and supporting the second shaft, and as the first housing and the second housing rotate from a closed state in which they are stacked to an open state, the link protrudes from a surface that does not face the second housing in the closed state. Effect of the Invention

[0008] According to the above-described aspect of the present invention, when the first housing and the second housing are stacked in the closed state, the link hardly protrudes, resulting in a suitable design, and when in the open state, the link protrudes, ensuring a gap of appropriate width between the housing and the placement surface.

[0010] Hereinafter, an embodiment of a hinge device and an electronic device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiment. The embodiment of the present invention is a hinge device 10 and an electronic device 12 including the hinge device 10.

[0011] FIG. 1 is a schematic perspective view of an electronic device 12 equipped with a hinge device 10 according to an embodiment of the present invention, viewed from an oblique angle. FIG. 2 is a perspective view of the main body housing 14 and the display housing 16 in a closed state, as viewed from the display housing 16 side. FIG. 3 is a perspective view of the main body housing 14 and the display housing 16 in a closed state, as viewed from the main body housing 14 side. The electronic device 12 is a clamshell-type notebook PC in which the main body housing 14 and the display housing 16 are connected by the hinge device 10 so as to be relatively rotatable. The electronic device according to the present invention may be a flip-type mobile phone, a smartphone, a portable game machine, or the like, other than a notebook PC. In the following description, the left-right direction as viewed from an operator with the main body housing 14 as a reference is also referred to as the X direction (first direction), the depth direction perpendicular to the X direction is also referred to as the Y direction (second direction), and the up-down direction perpendicular to these directions is also referred to as the Z direction. In addition, the front of the Y direction is also referred to as the Y1 direction, and the rear of the Y direction is also referred to as the Y2 direction.

[0012] First, we will explain the overall configuration of the electronic device 12. In the electronic device 12, a rear end 14a, which is a connecting edge of a main body housing 14, and a lower end 16a, which is a connecting edge of a display housing 16, are connected by a pair of left and right hinge devices 10, 10 so as to be able to be opened and closed. The hinge device 10 does not have to be a pair on the left and right, and one or three or more hinge devices 10 may be installed.

[0013] The main body housing 14 is a flat box formed of an upper cover material and a lower cover material. The upper surface 14b of the main body housing 14 is formed of the upper cover material, and the lower surface 14c is formed of the lower cover material. A keyboard 20 and a touch pad 22 are provided on the upper surface 14b of the main body housing 14. Various electronic components such as a motherboard, a computing device such as a CPU, a memory, and a battery device are stored inside the main body housing 14.

[0014] A cooling device including a fan is provided inside main body housing 14 to cool the arithmetic unit and the like. The fan takes in air from intake holes (vents) 14d on bottom surface 14c and exhausts it from exhaust holes 14e on rear end 14a. The cooling device receives heat from the arithmetic unit through a heat pipe and a vapor chamber, and transports part or almost all of the heat to a heat sink, which dissipates the heat by the fan.

[0015] The display housing 16 is a flat box formed thinner than the main body housing 14. A display 18 is provided on the front of the display housing 16. The display 18 is, for example, a liquid crystal display or an organic light emitting diode (EL) display. The closed state (see Figs. 2 and 3) in which the main body housing 14 and the display housing 16 face each other is defined as an opening angle of 0 degrees. In the electronic device 12 of this embodiment, the maximum opening angle is 135 degrees (see Fig. 1). The state in which the main body housing 14 and the display housing 16 are stacked and the opening angle is 0 degrees is called a closed state. The state in which the opening angle is 135 degrees is called a maximum open state. In the closed state, the upper surface 14b is the surface facing the display housing 16, and the opposite lower surface 14c is the surface not facing the display housing 16.

[0016] As shown in Fig. 3, the bottom surface 14c of the main body housing 14 is basically not provided with legs, and the entire surface is almost flat, realizing a suitable design, especially in the closed state. However, small legs may be provided as long as they do not impair the design. Electronic device 12 without large legs is suitable for carrying in a bag or the like.

[0017] Next, a specific example of the configuration of the hinge device 10 and its surroundings will be described. FIG. 4 is a perspective view of the hinge device 10 and its surroundings. FIG. 5 is a perspective view of the hinge device 10 with the cover 26 removed from FIG. 4. FIG. 6 is a perspective view of the hinge device 24 removed from FIG. 5. FIG. 7 is a perspective view of the hinge device 10 with the right side plate 56 and the peripheral wall 58 removed from FIG. 6. FIGS. 4 to 7 show the maximum open state. The left and right hinge devices 10 are symmetrical or have the same configuration, so the following description will be given of one of the hinge devices 10, and the description of the other hinge device 10 will be omitted.

[0018] The hinge device 10 is provided near one end of the electronic device 12 in the X direction, from the main body housing 14 to the display housing 16, passing through a notch 14g at the Y2 end. The display housing 16 has two countersunk portions 28 and a clearance portion 30 formed at a lower end 16a. The countersunk portions 28 are portions to which a bracket 44a, which will be described later, is attached. The clearance portion 30 is a recess that avoids interference with a link 52, which will be described later, in the closed state, and has an acute-angled cross-sectional shape that becomes deeper as it approaches the lower end 16a.

[0019] A rectangular recess 14f that communicates with the notch 14g is formed on the top surface 14b of the main body housing 14. The recess 14f is composed of a first recess 14fa and a second recess 14fb that have different depths. The first recess 14fa is a shallow recess that is slightly on the Y1 side from the rear end 14a and is formed so as to surround three sides of the second recess 14fb and is wider than the notch 14g.

[0020] The second recess 14fb is slightly deeper than the first recess 14fa, has the same width as the notch 14g, and communicates with the rear end 14a via the notch 14g. The Y-direction width of the second recess 14fb is about half that of the first recess 14fa. The second recess 14fb is formed by a fixed base 14fba on the Y1 side and a slider passing portion 14fbb on the Y2 side, with a step as a boundary. The fixed base 14fba is a portion to which the base plate 40 described later is fixed, and is slightly deeper than the Z-direction width of the base plate 40. The slider passing portion 14fbb is slightly deeper than the fixed base 14fba so that the slider 48 described later can pass through.

[0021] The first recess 14fa is provided with a touch device (input / output device) 24 that slides and displaces in the Y direction together with a pin 60 provided on a link 52 described later. An engagement groove 24b (see FIG. 5) for the pin 60 is formed on the bottom surface of the touch device 24. The engagement groove 24b is slightly elongated in the Z direction to accommodate the rotational movement of the pin 60. The touch device 24 is thin and has a rectangular shape that is slightly wider than the second recess 14fb, and displaces to the Y2 side in the maximum open state to cover the second recess 14fb. An operation unit 24a that is long in the X direction is provided on the Y2 side portion of the touch device 24. For example, various icons (not shown) are displayed on the operation unit 24a of the touch device 24, and predetermined processing is performed by touching these icons.

[0022] The first recess 14fa is covered with a cover 26. A notch 26a is formed on the Y2 side of the cover 26 to expose the operation unit 24a in the fully open state. The operation unit 24a is almost entirely exposed from the notch 26a even when the opening / closing angle is, for example, about 120 degrees. As shown by the imaginary line in FIG. 4, in the closed state, the touch device 24 is displaced furthest toward the Y1 side within the first recess 14fa. At this time, the operation unit 24a is covered and protected by the cover 26. The cover 26 forms a continuous surface with the top surface 14b.

[0023] FIG. 8 is a perspective view of an electronic device 12A according to a modified example. In FIG. 8, a keyboard and a touch panel are omitted. In the above electronic device 12, a relatively small touch device 24 is provided for each of the two hinge devices 10 on the left and right, whereas one touch device 24A provided in the electronic device 12A is set long in the X direction across the two hinge devices 10 on the left and right. The touch device 24A slides in the Y direction by opening and closing the display housing 16, similar to the touch device 24. The recess formed on the upper surface 14b in which the touch device 24A slides, and the cover 26A covering approximately half of the Y1 side of the recess, are formed long in the X direction. In the closed state, the touch device 24A is covered by the cover 26A. The input / output device that slides under the action of the hinge device 10 is not limited to the touch devices 24 and 24A, and may be, for example, a microphone, a speaker, or the like.

[0024] The hinge device 10 will be further described with reference to FIGS. Fig. 9 is a perspective view of the hinge device 10. Fig. 10 is a perspective view of the hinge device 10 with the side plate 56 and the peripheral wall 58 removed. Figs. 9 and 10 show the hinge device 10 in a closed state. The hinge device 10 has a base plate 40, a first shaft 42, a second shaft 44, a crank 46, a slider 48, a torque application portion 50, and a link 52. The hinge device 10 constitutes a kind of slider-crank mechanism by the crank 46, the slider 48, and the link 52.

[0025] For the convenience of assembly, the base plate 40 is configured by a first member 40a on the left side and a second member 40b on the right side being meshed with each other. The width of the first member 40a in the Y direction is larger than that of the second member 40b. The base plate 40 has a plurality of screw holes 40c formed near the Y1 side end, and this portion is screwed to the fixed base 14fba, and the other portion protrudes in the Y2 direction with a gap secured to the slider passing portion 14fbb. A support portion 40d that supports the first shaft 42 rotatably protrudes from both ends of the Y2 side end of the base plate 40. In other words, the first shaft 42 is supported by the main body housing 14 via the base plate 40. The first shaft 42 extends in the X direction within the range of the notch 14g near the rear end 14a. A male screw is formed at the right end of the first shaft 42. In this embodiment, the width of the base plate 40 in the X direction and the width of the Y direction excluding the support portion 40d are approximately equal.

[0026] The second shaft 44 is parallel to and aligned with the first shaft 42, and is fixed to the display housing 16 near the lower end 16a by brackets 44a provided on both ends being fitted into the countersunk holes 28 and screwed in. The first shaft 42 is located in a relatively lower portion of the main body housing 14, and the axial distance between the first shaft 42 and the second shaft 44 is appropriately long.

[0027] The crank 46 has an oval shape and is provided between the two shaft supports 40d, and is non-rotatably fitted and connected to the first shaft 42 and the second shaft 44 at both ends by a predetermined anti-rotation means. The angle between the crank 46 and the display housing 16 is approximately 90 degrees (see FIG. 11), and in the closed state, the crank 46 is oriented along the Z direction.

[0028] The slider 48 has a rectangular shape in front view, fits into the base plate 40 with almost no gap, and surrounds the base plate 40. The slider 48 is slidable in the Y direction within the range facing the slider passing portion 14fbb. The slider 48 is on the Y1 side of the first shaft 42, and slides toward and away from the first shaft 42. The base plate 40 has a function of guiding the slider 48 so that it can slide, as well as a function of supporting the first shaft 42, which is reasonable, but the two functional parts may be separate. Short shafts 48a protrude from both ends of the slider 48 in the X direction (only the right side is shown in FIG. 10). The slider 48 has an appropriate width in the Y direction so that it can slide easily.

[0029] The torque applying unit 50 applies a rotation torque due to friction to the first shaft 42 to maintain the display housing 16 at any angle, and includes a flange 50a at the left end of the first shaft 42, a nut 50b that screws into the male thread at the right end, and a plurality of fixed washers 50c and a disk 50d that fit on the first shaft 42 between them. The disk 50d is a plate spring formed of a dish-shaped metal plate, and a plurality of disks 50c are stacked between the nut 50b and the right-side support portion 40d via the fixed washers 50c. The fixed washers 50c are also provided between the two support portions 40d and the crank 46. The fixed washers 50c are made non-rotatable with respect to the first shaft 42 by a predetermined rotation prevention means. The torque applying unit 50 generates an axial force on the first shaft 42 by tightening the nut 50b, and the disks 50d are elastically compressed, thereby generating an axial friction force on the first shaft 42. It is advisable to apply a loosening prevention treatment to the nut 50b.

[0030] The link 52 will be described with reference to Figures 2, 3, 9, and 10, which show the closed state. The link 52 is mainly composed of a left side plate 54, a right side plate 54, and a peripheral wall 58. The peripheral wall 58 is oriented horizontally and has an irregular pentagonal cylindrical shape. The side plates 54, 56 fit into and close the left and right openings of the peripheral wall 58. The peripheral wall 58 does not reach the lower part on the Y1 side, and an opening 52a is formed therein through which the slider 48 can be inserted.

[0031] Shaft holes 54a, 56a that rotatably support the second shaft 44 are formed near the upper ends of the side plates 54, 56 on the Y2 side. An inward bulging portion 56b is formed in the lower portion of the side plate 56 on the Y1 side. The bulging portion 56b ensures a space for arranging the nut 50b, fixed washer 50c, and disk 50d of the torque application portion 50.

[0032] A slider shaft hole 56c is formed on the inner surface of the bulging portion 56b, which supports the X-direction shaft 48a on the right side surface of the slider 48. Although not shown, a slider shaft hole is formed in the left side plate 54 at a similar position, which supports the X-direction shaft 48a on the left side surface of the slider 48. In other words, the link 52 supports the slider 48 in the X direction and also supports the second shaft 44.

[0033] In this embodiment, the axial distance between the axis 48a and the first shaft 42 in the closed state is about 1.5 times the axial distance between the first shaft 42 and the second shaft 44. In this embodiment, the width of the link 52 in the Y direction is about twice the axial distance between the first shaft 42 and the second shaft 44. The link 52 does not axially support the first shaft 42.

[0034] The slider shaft hole 56c has a bottom corresponding to the short shaft 48a, but may be a through hole. The shaft 48a may be provided in the side plates 54, 56, and the slider shaft hole 56c may be provided in the slider 48. The side plate 56 is provided with an L-shaped member 56d that protrudes inward. An axis hole through which the second shaft 44 is inserted is formed in the bent tip portion of the L-shaped member 56d, and the L-shaped member 56d auxiliarily supports the second shaft 44 in the vicinity of the crank 46.

[0035] The link 52 has five main surfaces defined by the peripheral wall 58: a rear surface 52b, a front surface 52c, an upper surface 52d, a lower surface 52e, and an inclined surface 52f.

[0036] In the closed state, the rear surface 52b forms a continuous surface with the rear end portion 14a of the main body housing 14 and the lower end portion 16a of the display housing 16. The upper surface 52d and the upper arc portion 52g between the rear surface 52b and the upper surface 52d form a continuous surface with the rear cover 16b on the opposite side to the display surface of the display housing 16. The lower arc portion 52h between the rear surface 52b and the lower surface 52e forms a continuous surface with the lower cover material of the main body housing 14. In this way, in the closed state, the link 52 has an integrated appearance that is continuous with the main body housing 14 and the display housing 16, which is preferable in terms of design. The lower arc portion 52h has a moderately gentle arc shape.

[0037] The upper surface 52d has a shorter width in the Y direction than the lower surface 52e, which is about 1 / 3 in this embodiment and is relatively inconspicuous. A gently inclined surface 52f is provided between the upper surface 52d and the front surface 52c. The inclination angle of the inclined surface 52f and the clearance portion 30 (see FIG. 11(a)) is equal, and they face each other with almost no gap when closed. The lower surface 52e is inclined slightly upward toward the Y1 side to avoid interference with other members such as a cover.

[0038] The upper half of the front surface 52c is slightly inclined toward the Y2 side. Small pin bases 50g are provided to protrude from both the left and right ends of this inclined portion of the front surface 52c. Pins 60 protrude in directions away from each of the two pin bases 50g. Each pin 60 fits into an engagement groove 24b (see FIG. 5) formed on the underside of the touch device 24, and drives the touch device 24 to slide. The means for driving the touch device 24 to slide may be provided on the slider 48.

[0039] FIG. 11 is a schematic cross-sectional side view of the hinge device 10 and its surrounding areas, in which (a) shows the 0 degree or closed state, (b) shows the 60 degree state, (c) shows the 90 degree state, and (d) shows the 135 degree or maximum open state.

[0040] As shown in Fig. 11(a), in the closed state, the second shaft 44 is located directly above the first shaft 42. At this time, the slider 48 is displaced furthest toward the Y1 side. The link 52 is contained within the contour range of the main body housing 14 and the display housing 16, and the lower arc portion 52h coincides with the contour portion of the main body housing that extends from the lower surface 14c to the rear end portion 14a. However, depending on the conditions, a part of the link 52 may slightly protrude from the lower surface 14c.

[0041] As shown in FIG. 11(b), when the opening / closing angle is 60 degrees, the second shaft 44 moves from the closed state position to a position of 60 degrees in the clockwise direction with the first shaft 42 as the rotation reference, and displaces in the Y2 direction and downward by that amount. The link 52, since the shaft shaft hole 56a supports the second shaft 44, displaces in the Y2 direction and downward while rotating. Also, the link 52 supports the shaft 48a of the slider 48 at the slider shaft hole 56c, but since the slider 48 can slide in the Y direction but cannot displace in the Z direction, it is displaced as if it is drawn in the Y2 direction by the second shaft 44. Therefore, the link 52 displaces in the Y2 direction while rotating with the shaft 48a of the slider 48 as the apparent reference. Then, the lower arc portion 52h displaces in the Y2 direction and downward and protrudes from the lower surface 14c of the main body housing 14.

[0042] As shown in Fig. 11(c), when the opening / closing angle is 90 degrees, the second shaft 44 moves from the closed state position to a position at 90 degrees clockwise with the first shaft 42 as the rotation reference, and displaces in the Y2 direction and downward by that amount. The link 52 displaces in the Y2 direction and downward while rotating with the axis 48a of the slider 48 as the reference. At this time, the second shaft 44 and the slider 48 are displaced to the maximum in the Y2 direction. The lower arc portion 52h protrudes further downward than when the opening / closing angle is 60 degrees. At this time, the lower arc portion 52h is located about 40 degrees counterclockwise from the vertical downward direction with the axis 48a as the reference.

[0043] 11(d), in the maximum open state, the second shaft 44 moves to a position at 135 degrees clockwise from the closed state position with the first shaft 42 as the rotation reference, and displaces downward by that amount and returns slightly in the Y1 direction. The link 52 displaces downward while rotating with the axis 48a of the slider 48 as the reference, and returns slightly in the Y1 direction. The lower arc portion 52h displaces clockwise from the state where the opening / closing angle is 90 degrees, and in this embodiment, with the axis 48a as the reference, it protrudes further downward to a position about 15 degrees counterclockwise from vertically downward.

[0044] 12 is a schematic side view of the electronic device 12 in the maximum open state. In the maximum open state, the lower arc portion 52h of the link 52 protrudes moderately downward from the bottom surface 14c of the main body housing 14 at the lower part of the rear end portion 14a. Therefore, the main body housing 14 has a moderate upward inclination at the rear. In this embodiment, the inclination is about 2 to 3 degrees with respect to the placement surface G.

[0045] By tilting the main housing 14, a gap Ga of an appropriate width is ensured between the lower surface 14c and the placement surface G, and the intake resistance from the intake holes 14d (see FIG. 3) can be reduced. In addition, the appropriate tilt of the main housing 14 makes typing on the keyboard 20 easier. The lower arc portion 52h has a gentle arc shape, which is suitable for placement. The hinge device 10 can be called a frame lift-up hinge, since the link 52, which essentially constitutes part of the frame, protrudes downward to lift up the main housing 14.

[0046] The present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention. [Explanation of symbols]
