Like reference numbers in the various drawings are used wherever feasible to indicate like elements. Further, the left-most numeral of each reference number conveys the FIG. and associated discussion where the reference number is first introduced.

    DETAILED DESCRIPTION



    [0004] The present concepts relate to devices, such as computing devices employing recessable hinge assemblies that can rotationally secure two device portions. The recessable hinge assemblies can also bias the device portions to specific orientations, such as closed and open orientations. In the open orientation the hinge assembly can be configured to allow the device portions to abut one another to create a near seamless display area across the device portions.

    [0005] Introductory FIG. 1 shows an example device 100. In this example, the device 100 has first and second portions 102 and 104 that are rotatably secured together by a hinge assembly 106. The first portion 102 can extend from a hinge end 108 to a distal end 110. The second portion 104 can extend from a hinge end 112 to a distal end 114. The first portion can include opposing first and second major surfaces 118 and 120 (hereinafter, first and second surfaces). Similarly, the second portion can include opposing first and second major surfaces 122 and 124 (hereinafter, first and second surfaces).

    [0006] Instance One shows device 100 in a closed orientation. The closed orientation can be viewed as defining a near zero degree angle between the first and second portions as measured relative to the hinge assembly 106.

    [0007] Instance Two shows second portion 104 rotated 180 degrees counter-clockwise from Instance One so that the device is now in a fully open orientation (e.g. at 180 degrees), and the first portion 102 and the second portion 104 are adjacent and coplanar. Thus, if displays 126(1) and 126(2) (shown partially) are employed on the first surfaces 118 and 122, in the fully open position these displays can be addressed (e.g., treated) as a single display with larger (e.g. 2x) dimensions.

    [0008] Instance Three shows first portion 102 rotated 180 degrees clock-wise so that the device is now again in the closed orientation except that now the displays 126 are inward facing and positioned against one another and are protected by the first and second portions 102 and 104. Rather than referring to this as zero degrees, this configuration can be viewed as 360 degrees since in Instance One, the second surfaces 120 and 124 were positioned against one another and the first surfaces 118 and 122 were outwardly facing. Now the first surfaces 118 and 122 are positioned against one another and the second surfaces 120 and 124 are outwardly facing.

    [0009] As mentioned above, in some configurations, the first surfaces 118 and 122 can be manifest as displays 126, such that in the fully open orientation of Instance Two the displays can work cooperatively to create a larger (e.g., 2x) display area. In some cases, the second surfaces 120 and 124 can be manifest as protective covers so that in the configuration of Instance One, the protective covers protect the displays of the first surfaces. In other configurations, both the first and second surfaces can be displays, or neither can be displays.

    [0010] FIGS. 2-4 show the first and second portions 102 and 104 in ghost so that underlying components can be visualized. Magnets 202(1) are contained in the first portion. Note that not all of these magnets are shown so that other components can be distinguished. The function of these magnets is explained below relative to FIG. 21.

    [0011] As shown in FIGS. 2-7 hinge assembly 106 includes a first hinge sub-assembly 204(1) and a second hinge sub-assembly 204(2). A spine 206 extends between the first hinge assembly and the second hinge assembly. The spine can provide structural support to the hinge assembly. Further, the spine can include magnets 208. The magnets 208 can interact with the magnets 202 to predispose the device into specific angles, such as zero, 180, and/or 360 degrees, among others. This aspect is discussed in more detail below relative to FIG. 21.

    [0012] First and second hinge sub-assemblies 204(1) and 204(2) can include first and second hinge arms 210A(1) and 210A(2) and 210B(1) and 210B(2). As shown in FIG. 2, a flexible circuit 212 (such as a flexible printed circuit (FPC)) can pass through one or both of the hinge sub-assemblies 204. In this case, first flexible circuit 212A passes through the first hinge sub-assembly 204(1) and second flexible circuit 212B passes through second hinge sub-assembly 204(2).

    [0013] FIGS. 5-7 show the hinge assemblies in isolation in views similar to those of FIGS. 3, 2, and 4, respectively.

    [0014] FIGS. 8-14 show enlarged views of first hinge sub-assembly 204(1) and a portion of spine 206. In this implementation, a cover plate 802 (removed FIG. 10 to show underlying structures) and spine 206 cooperatively define opposing slots 806(1) and 806(2) (FIGS. 8-9) through which flexible circuit 212A (FIGS. 13-14) can pass. The slots 806 are aligned with passageways 808 (FIGS. 8-9) defined between the hinge arms 210A and the spine 206. The slots 806 and the passageways 808 can protect the flexible circuits 212A (FIGS. 13-16) passing from one device portion to the other (e.g., from first portion 102 to second portion 104 as seen in FIG. 2). Thus, through the range of rotations, the flexible circuits are protected by and mostly or fully covered by the spine 206 and hinge arms 210A.

    [0015] In this implementation, cover plate 802 helps to secure the hinge arms 210A to the spine 206. FIG. 10 shows the cover plate removed so that upwardly and downwardly facing hinge pins 1002 and 1004 of the hinge arms can be visualized. The hinge pins 1002 and 1004 operate cooperatively with the cover plate 802 and the spine 206 to define a rotational path of the hinge arms 210A. Stated another way, each pair of upwardly and downwardly facing hinge pins (e.g., hinge pins 1002(1) and 1004(1) define an axis of rotation for hinge arm 210A(1) and hinge pins 1002(2) and 1004(2) define an axis of rotation for hinge arm 210A(2). The hinge pins may also move laterally during this rotation. This aspect is described in more detail below relative to FIGS. 17-19.

    [0016] Note also, as labeled relative to FIG. 14, the hinge arms 210A define openings 1402A(1) and 1402A(2). The function of the openings is described below relative to FIG. 15.

    [0017] FIGS. 15 and 16 show views of device 100 that are similar to Instance One and Instance Two of FIG. 1. In this case, the first surfaces are removed. In FIGS. 15 and 16, the second surfaces 120 and 124 of the first portion 102 and the second portion 104, respectively, are defined by a frame or housing 1502(1) on the first portion and another frame or housing 1502(2) on the second portion. The hinge arms can be slideably secured to the housing 1502. In this case, the housing 1502 includes two pairs of spaced apart rails 1504A. An outer surface of the pairs of rails corresponds to an inner surface of openings 1402A in the hinge arms 210A. The hinge arms are retained in the z-reference direction between the housing 1502 and the first surfaces (not shown). However, the hinge arms can slide in the y-reference direction for a distance D defined by the inter-relation of the pairs of rails 1504A and the openings 1402A. Mechanically, this sliding of the hinge arms can contribute to the device having a wide range of rotations (e.g., 360 degrees of rotation) and to the first and second portions directly abutting one another in the fully open (e.g. 180 degree) orientation of FIG. 16.

    [0018] Several electronic components, such as circuit boards 1506(1) and 1506(2), a processor 1507, and/or storage/memory (not specifically designated) can be secured to the housings 1502(1) and 1502(2), respectively. The flexible circuit 212A (shown in FIG. 16., removed in FIG. 15) can be electrically coupled to these electronic components. In this case, the ends of the flexible circuit can include couplers 1508 that can be readily received by corresponding couplers 1510 on the housing (e.g., the flexible circuit couplers 1508 can snap into the corresponding couplers 1510) to quickly electrically couple the two device portions. Due to space constraints, the couplers are only labeled relative to second portion 104.

    [0019] The processor 1507 can generate graphical user interfaces (GUIs) for presentation on the displays (126, FIG. 1). In some implementations, the processor may generate different GUIs for the displays when the first and second portions 102 and 104 are in some orientations and a single GUI for a combined presentation in other orientations. For instance, when the first and second portions are oriented at 90 degrees relative to one another, the processor may generate a first GUI for presentation on the first portion and a second GUI for presentation on the second portion. When the first and second portions are oriented to 180 degrees, the processor can generate a single GUI that is collectively presented across both displays to create a larger display area.

    [0020] Note that in FIG. 15 where the device is closed (e.g., at zero degrees or at 360 degrees), the hinge arm 210A(2) has moved fully to the left (e.g., in the negative y-reference direction) relative to pair of rails 1504A(1) and 1504A(2). This allows the hinges to operate and allow rotation of device portions 102 and 104 to acute angles (e.g., toward zero and toward 360). In contrast, in the fully open orientation of FIG. 16, the hinge arm 210A(2) has moved fully to the right (e.g., in the positive y-reference direction) relative to pair of rails 1504A(1) and 1504A(2). This orientation allows the first and second portions 102 and 104 to abut directly against one another with no (or little) gap in between. Stated another way, in the fully open orientation of FIG. 16, the spine 206 and the hinge axes (defined by hinge pins (cover plate removed and labeled in FIG. 15)) are contained within the first and/or second portions 102 and 104.

    [0021] Recall that as mentioned above relative to FIGS. 8-10, the cover plate 802 and spine 206 also cooperatively define opposing slots 806(1) and 806(2) (FIGS. 8-9) through which flexible circuit 212A can pass. The slots are aligned with passageways 808 (FIGS. 8-9) defined between the hinge arms 210A and the spine 206. The slots 806 and the passageways 808 can protect the flexible circuits passing from one device portion to the other. Thus, through the range of rotations, the flexible circuits are protected by and mostly or fully covered by the spine 206 and hinge arms 210A. As shown in FIGS. 15 and 16, the slideable attachment of the hinge arms 210A when combined with the slots 806 and passageways 808 of FIGS. 8-9 can allow the flexible circuit 212A to be protected by the hinge sub-assembly 204(1) when rotated through a range of orientations from 0 degrees to 360 degrees.

    [0022] FIG. 17 shows a sectional view of device 100 along the yz-reference plane as indicated in FIG. 8. Instance One shows oval hinge bores 1702(1) and 1702(2) formed by the cover plate 802 and the spine 206. Instance Two shows hinge pins 1002(1) and 1002(2) of hinge arms 210A(1) and 210A(2) (shown in ghost). The hinge pins 1002 are positioned in the oval hinge bores 1702(1) and 1702(2). The oval hinge bores allow lateral movements of the hinge pins (e.g., in the z-reference direction) during rotation of the hinge arms (and hence the device portions) around the hinge pins.

    [0023] FIG. 18 shows a sectional view of device 100 along the yz-reference plane as indicated in FIG. 8. Instance One shows hinge pins 1002(1) and 1002(2) in oval hinge bores 1702(1) and 1702(2). Hinge pins 1002(1) and 1002(2) are associated with hinge arms 210A(1) and 210A(2), respectively. The hinge arms 210A(1) and 210A(2) are associated with first and second portions 102 and 104 (shown in ghost), respectively. Note that at this point, the first and second portions 102 and 104 are parallel to one another in a closed position (e.g., defining a zero degree angle α there between).

    [0024] FIG. 18 introduces cams 1800(1) and 1800(2) that control distance D between the hinge arms 210A during rotation. In this case, the cams are manifest as cam surfaces 1802 and 1804. Cam surfaces 1802 are defined by the hinge arms 210A and cam surfaces 1804 are defined by the spine 206 and cover plate 802 (labeled in Instance Three).

    [0025] Instance One shows first cam surfaces 1802 on the hinge arms 210A and second cam surfaces 1804 on the spine and cover plate. The interrelationships of the cam surfaces 1802 and 1804 and the hinge pins 1002 in oval hinge bores 1702 control relative spacing of the hinge arms during opening and closing. In the closed position of Instance One, the hinge pins 1002 are spaced as far apart from one another as the oval hinge bores allow (e.g., represented by hinge pin to hinge pin distance D1). Further, the cam surfaces 1802 and 1804 are not engaging one another. (FIG. 19 shows an enlarged view of cam surfaces 1802(1) on hinge arm 210A(1)).

    [0026] Instance Two shows the device 100 at a point where the user has opened the first and second portions 102 and 104 until angle α is about 90 degrees. At this point in the rotation, the shape of cam surface 1802 causes cam surfaces 1802 and 1804 to engage one another, which maintains spacing (D2) between hinge pins 1002(1) and 1002(2). This cam action also spaces inner corners 1806(1) and 1806(2) of the first and second portions 102 and 104 from one another. This feature can prevent the first and second portions from striking each other at the inner corners 1806 and causing damage during rotation. For instance, the first and second portions might be covered with glass displays which if they struck each other could cause damage, such as chipping. This feature reduces/eliminates this risk of damage.

    [0027] Instance Three shows device 100 rotated until the first and second portions are coplanar (e.g., angle α is 180 degrees). At this point, the shape of cam surface 1802 allows the first and second portions to move toward one another (e.g., distance D3 is less than distances D1 and/or D2. In this case, the first and second portions are coplanar and abutting one another. Thus, in an implementation where displays (126, FIG. 1) are employed on first surfaces 118 and 122 and/or second surfaces 120 and 124, a large (e.g. 2x) nearly seamless display area can be created. Further details of device 100 in the fully open configuration are illustrated in FIG. 20.

    [0028] Instance Four shows continued rotation so that angle α is about 270 degrees. At this point, the shape of cam surface 1802 causes this cam surface to engage cam surface 1804 to force the hinge pins 1002 apart to protect inner corners 1808(1) and 1808(2). Thus, distance D4 is larger than D3 and about the same as D2.

    [0029] Instance Five shows the first and second portions 102 and 104 parallel to one another and about 360 degrees from the orientation of Instance One.

    [0030] Thus, the cams 1800 can bring the hinge end of the first portion 102 and the hinge end of the second portion 104 toward one another when the device is opened, such as going from Instance One where the first and second portions are adjacent and coplanar to Instance Two where the first and second portions define a right angle or an oblique angle. During this rotation, the cams 1800 can extend the hinge end of the first portion and the hinge end of the second portion away from one another to protect the inner corners 1808.

    [0031] FIG. 19 shows details of the shape of camming surface 1802(1) of hinge arm 210A(1) as mentioned above relative to FIG. 18.

    [0032] FIG. 20 shows details of device 100 in the fully open configuration (in this case 180 degrees) mentioned above relative to Instance Three of FIG. 18. Further, FIG. 20 shows recesses 2002(1) and 2002(2) that are occupied by the hinge assembly 106 when the device is in the fully open configuration as the hinge arms 210A slide into the device portions as mentioned relative to FIG. 16. For instance, hinge arm 210A(2) slides in the negative z-reference direction into first portion 102 and hinge arm 210A(1) slides in the positive z-reference direction into second portion 104. The hinge assembly 106 sliding into recesses 2002(1) and 2002(2) can allow surfaces 118 and 122 and 120 and 124 to abut one another. In one configuration, the first surfaces 118 and 122 can be manifest as displays so that a single graphical user interface can be collectively presented across both displays to effectively double the display area. The second surfaces 120 and 124 can alternatively or additionally be manifest as displays that receive another graphical user interface for collective presentation.

    [0033] Recall that FIG. 18 shows how the first portion 102 and second portion 104 can be rotated from zero degrees to 360 degrees. FIG. 21 shows how the device can impart forces on the first and second portions to bias the first and second portions toward specific relative angular orientations.

    [0034] FIG. 21 is a sectional view as indicated in FIG. 5. FIG. 21 shows how magnets 202(1), 202(2), and 208 can operate cooperatively to create forces that bias the device portions 102 and 104 toward specific orientations. Thus, from one perspective, magnets 202(1), 202(2), and 208 can be thought of as a magnetic assembly 2100 that is configured to bias the first and second portions to specific angular orientations or configurations.

    [0035] Instance One shows the device portions 102 and 104 in a closed configuration (e.g., angle α is 360 degrees) where the portions overlay one another. Magnets 202(1) and 202(2) interact (e.g., attract one another) to create a bias toward this closed configuration. For instance, the North (N) pole of magnet 202(2) is positioned proximate to the South (S) pole of magnet 202(1) and the North Pole of magnet 202(1) is positioned proximate to the South Pole of magnet 202(2). The attraction between the magnets creates a force holding the first and second portions in this closed configuration. A user can apply a greater force to overcome the magnetic force and open the device.

    [0036] Instance Two shows the device opened to about 220 degrees, which can be termed an intervening orientation (e.g., between closed and fully open). At this point magnetic attraction between the magnets 202 in the first and second portions 102 and 104 and magnets 208 in the spine 206 create a force that biases the device to continue to open. Specifically, the force between magnets 202(1) and 202(2) is diminished compared to Instance One, but the attractive force between magnet 202(2) and magnet 208 and magnet 208 and magnet 202(1) is increasing. In Instance Two, the South Pole of magnet 202(2) is attracted to the North Pole of magnet 208 of spine 206. The South Pole of magnet 208 is attracted to the North Pole of magnet 202(1). This attraction can bias the device into the fully open configuration of Instance Three.

    [0037] Instance Three shows the spine magnet 208 interacting with magnets 202(1) and 202(2) in a manner that biases the device toward this fully open orientation where the first and second portions 102 and 104 are juxtaposed and coplanar. Not only do the magnets function to bias the first and second portions toward the fully open orientation, the magnets function to maintain the device in this fully open orientation. The attractive force between the magnets 202(2), spine magnets 208, and magnets 202(1) can also cause the device portions to be pulled together until the device portions abut one another (discussed above relative to FIG. 18 and also shown in FIG. 20).

    [0038] Instance Four show where the user has applied a force to fold or close the device. At this point, the attractive forces of the spine magnets 208 and the magnets 202 of the first and second portions 102 and 104 are decreasing and the attractive forces of the magnets 202(1) and 202(2) on each other is increasing. The attraction of magnets 202(1) and 202(2) can bias the device toward the orientation of Instance Five.

    [0039] Instance Five shows the device in a closed orientation (e.g., angle α equals zero degrees). This orientation is identical to the orientation of Instance One except that the inward and outward facing surfaces are reversed. The attraction between magnets 202(1) and 202(2) biases the device to maintain this orientation (e.g., the device portions will not rotate away from one another unless acted upon by a force, such as the user rotating them apart).

    [0040] FIGS. 22-23 show cross-sections of two spine implementations.

    [0041] FIG. 22 shows magnets 208(1) and 208(2) positioned at opposing ends of spine 206 with structural material 2200 interposed between. Structural material 2200 may be, for example, plastic or metal fabric overlaid with a cured polymer overlaid, cured foam, a combination of these materials, or other materials.

    [0042] FIG. 23 shows structural material 2200A in the form of an I-beam with the magnets 208(1) and 208(2) positioned in opposing recesses formed by the I-beam structure.

    [0043] Individual elements of the hinge assembly 106 can be made from various materials, such as metals, plastics, and/or composites. These materials can be prepared in various ways, such as in the form of sheet metals, die cast metals, machined metals, 3D printed materials, molded or 3D printed plastics, and/or molded or 3D printed composites, among others, or any combination of these materials and/or preparations can be employed.

    [0044] The present hinge assembly concepts can be utilized with any type of device, such as but not limited to notebook computers, smart phones, wearable smart devices, tablets, and/or other types of existing, developing, and/or yet to be developed devices. EXAMPLE METHODS

    [0045] Various methods of manufacture, assembly, and use for hinge assemblies and devices are contemplated beyond those shown above relative to FIGS. 1-23.
