Description

BACKGROUND

[0001] US 2012 / 0066865 A1 describes a magnetic fastening mechanism and a method. The magnetic fastening mechanism can be used to detachably connect at least two objects in a preferred configuration without fasteners and without external intervention. The magnetic fastening mechanism can be used to detachably attach an accessory to an electronic device. The accessory can be used to enhance the functionality or utility of the electronic device.

[0002] US 7,308,733 B2 describes a swivel-joint assembly for use in an electronic device, such as a portable electronic device. The swivel-joint assembly comprises a first rotating shaft configured to rotate about a substantially vertical axis, a base configured to rotate through the first rotating shaft in a substantially horizontal plane, and a second rotating shaft mounted on the base, at least a portion of which is configured to rotate about a substantially horizontal axis intersecting the first rotating shaft. The swivel-joint assembly may further include a cover plate configured to cover an opening formed on the top of a main body of the electronic device, in which the base rotates.

[0003] EP 1 780 505 A2 describes a magnetic field sensor device that can be implemented using a magnetic sensor in both electronic compasses and circuits. A magnet can be placed in close proximity to the magnetic sensor in an electronic compass to generate a signal indicating that a portable information device has been closed. This signal can be input to a processor or other circuit to trigger a response to the closing of the portable information device. When the magnet is removed from the immediate vicinity of the magnetic sensor, the magnetic sensor can be used in the electronic compass. Thus, one magnetic sensor can perform two functions: compass and switch, thereby reducing the need for separate sensors to perform both functions. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The object underlying the invention is to improve and make more flexible the integration between an electronic device and an accessory. This object is achieved by the subject matter of claim 1 and the dependent claims. Further advantageous embodiments are specified in the sub-claims. DETAILED DESCRIPTION OF EXAMPLE EXECUTION FORMS

[0007] The following detailed description presents example embodiments of devices, methods, and systems with respect to joint configurations for an electronic device. Features such as structure(s), function(s), and / or property(ies) are described for simplicity with reference to one embodiment; different embodiments can be implemented with any suitable one or more of the described features.

[0008] Traditionally, tablet devices and their associated accessories have exhibited minimal integration. A keyboard accessory, for example, is often an afterthought, requiring a combination of elastic elements and / or magnets to connect the two disparate components, without any power integration between them (e.g., no power integration between a tablet and a keyboard accessory). Coupling the tablet to the accessory may provide a limited range of motion for angling the tablet in a laptop-like orientation, or it may only allow fixed angular orientations. Furthermore, the keyboard-device interaction may only permit one orientation of the keyboard relative to the device when connected (i.e., the device screen only facing the keyboard).This configuration limits the user's flexibility, along with hindering the overall user experience with the device when used in laptop orientation.

[0009] Particular embodiments described herein provide for an electronic device, such as a notebook, laptop, mobile phone, or other mobile device, which includes a printed circuit board coupled to several electronic components (including any type of component, element, circuit, etc.). The electronic device may also include a lower section and an upper section, the latter being connected to the lower section by a hinge configured such that the lower section and the upper section can be rotated between an open configuration of the electronic device and a closed configuration of the electronic device (with holding positions relative to each other at points between the open and closed positions).Certain embodiments presented herein can provide effective joint and coupling capability, which provides alignment flexibility and connection to enable more extensive integration between the electronic device (e.g., a tablet) and an accessory (e.g., a keyboard, an audio system, a movie player system, a docking station, an accessory cover, etc.).

[0010] The electronic device may also include a hinge assembly for selectively securing (e.g., based on a desired configuration) an upper section of the electronic device to an accessory. The hinge assembly allows the upper section to rotate relative to the accessory. The hinge assembly includes one or more discs for receiving one or more segments of the accessory when the hinge assembly engages to secure the upper section of the electronic device to the accessory. In more specific embodiments, the hinge assembly includes a gear disc for receiving the one or more segments of the accessory to secure the upper section to the accessory.Furthermore, the accessory may include one or more rib segments to provide an alignment function when the device's joint assembly engages with the accessory (thereby providing increased stability and rigidity to this region of the accessory). In an embodiment that includes magnets in this particular region of the accessory, these rib segments may provide the additional function of concentrating the magnets' magnetic force. The accessory may also include a tooth (or multiple tooth features) to provide resistance to rotational movement between the joint assembly and the accessory, allowing them to maintain their relative positions without user intervention. Additionally, the accessory may include one or more magnetic strips that attract one or more rings provided in the upper section.

[0011] In one embodiment, the accessory coupling features of the accessory do not include magnets. Instead, the device can be held by the accessory at the joint connection point by the accessory engagement features of the electronic device using a mechanical over-center (or other type) snap-in retainer.

[0012] In other embodiments, an electronic device is provided which includes a hinge assembly for selectively securing an upper section of the electronic device to an accessory. The hinge assembly allows rotation of the upper section relative to the accessory and includes at least a three-part snap-in configuration (or a four-part, a five-part, etc.) that provides a holding force between the upper section and the accessory. Power signals can be routed separately through each of the three parts of the three-part snap-in configuration. Alternatively, the power signals can be routed through a middle part of the three-part snap-in configuration, and two outer parts of the three-part snap-in configuration can be insulators.The accessory may be a keyboard which includes a keyboard-side snap-in element with a part, and multiple slots may be provided to allow independent movement of the keyboard's outer snap-in straps. JOINT CONFIGURATION FOR AN ELECTRONIC DEVICE

[0013] Fig. Figure 1A is a simplified schematic representation illustrating an embodiment of an electronic device 10 in an open configuration in accordance with an embodiment of the present disclosure. The electronic device 10 may include a lower section 16 comprising a keyboard 12 and a touchpad 18, and an upper section 14 comprising a display 26 and one or more disks 15. The display 26 may be arranged within, on, and / or supported by the upper section 14. In one or more embodiments, the display 26 is a screen, which may be an LCD (liquid crystal display), an LED (light-emitting diode) display, an OLED (organic light-emitting diode) display, a plasma display, or any other suitable display system.

[0014] In one or more embodiments, the electronic device 10 is a notebook or laptop. In other embodiments, the electronic device 10 can be any suitable electronic device that has a display, such as a mobile device, a tablet computer and / or tablet device (e.g., an iPad), a PDA (personal digital assistant), a smartphone, an audio system, a movie player of any kind, a computer docking station, etc.

[0015] In general, the electronic device 10 can provide a conveniently sized handle for an end user to manipulate the lower section 16 (e.g., to detach it from the upper section 14). The electronic device 10 can also include one or more discs 15, which provide an integrated detachable accessory solution from a mechanical, electrical, and aesthetic point of view. The accessory band design feature can provide mechanical and magnetic insertion assistance and attraction for retention during coupling. Furthermore, the electronic device 10 can employ a mechanical snap-in feature for easy attachment, retention, and detachment of an accessory. The power supply of the electronic device 10 can be physically separate from its housing and / or it can be integrated into one or more of its disc assemblies.Furthermore, the electronic device 10 can provide a coupling that allows the flow of power and / or data between the device and the accessory (e.g., keyboard) to which it is coupled. Additionally, the electronic device 10 can offer a space-saving integration of a coupling mechanism located within the volume of the disc feature. Furthermore, the electronic device 10 can provide an improved range of motion for the display when the device is oriented in laptop mode, as detailed below.

[0016] The electronic device 10 may also include a middle section located between the lower section 16 and the upper section 14. The middle section may aesthetically cover (or be located near) a portion of the joints 15 situated between the lower section 16 and the upper section 14. The joints 15 may define an axis of rotation common to both the lower section 16 and the upper section 14. In one embodiment, the lower section 16 and the upper section 14 are pivotally coupled via one or more joints 15 (as shown).

[0017] In the Fig. In the particular embodiment shown in Figure 1A, the electronic device 10 is a relatively thin and slim tablet with a touchscreen (e.g., a 10-inch screen) and a detachable and reattachable keyboard attachment. The electronic device 10 incorporates an integrated unit that can include a display section (containing a mainboard and batteries installed in a spring housing) and a keyboard section. Furthermore, its hinge mechanism allows the display section to be attached to the keyboard in two different orientations: with the display facing inwards and with the display facing outwards. This mechanism can provide the user with multiple modes (possible configurations), such as a laptop mode, tablet mode, movie mode (as well as a closed mode).All these configurations are discussed below with reference to various FIGURES which further illustrate some of the operational capabilities associated with the electronic device 10.

[0018] Regarding the specific magnetic keyboard design, it should be noted that keyboards currently available for tablets do not offer a suitable user experience. Typing on glass is ergonomically uncomfortable, and typical Bluetooth keyboards are thick and bulky. In contrast to these flawed systems, the keyboard option for the Electronic Device 10 can provide a user experience that replicates a more traditional computer keyboard experience. Furthermore, from the user's perspective, the key movement feels like that of a standard computer keyboard (for example, the movement might be approximately 0.5 mm versus 2.5 mm on a traditional computer keyboard, but it feels the same). Additionally, there is sufficient spacing between the keys to make it easier for touch typists to distinguish between them, resulting in improved touch typing.

[0019] In a particular embodiment, the keyboard is an ultra-thin (e.g., 3.30 mm), ultra-light (e.g., 275 grams) keyboard with sufficient keyboard band stiffness and stability to serve as a tablet device cover. The keyboard can be made of a laminate construction that uses variations of key design shapes and magnets to replicate a touch-typing user experience with the feel of a typical computer keyboard. To accommodate the thinner side areas of the keyboard device, the keyboard edge keys can be cantilevered on one side and, furthermore, in a particular embodiment of the present disclosure, can have magnets only on one side. The keys can be of any suitable type, such as toggle operation keys, with an arrow key operation combining four keys that cannot move diagonally. A magnet can be provided at various positions on the keyboard (e.g.,(away from the center of the keys).

[0020] In operation, the spacing between the keyboard keys allows a touch typist to easily distinguish between keys with their fingers. The edge keys can be specially designed for the thinner sides and may also utilize varying magnetic configurations. One edge key configuration allows keys to overhang the edge of the support base to accommodate the thinner sides of the keyboard. Magnets can be positioned to minimize any interference with key shifting. The shift key configuration is used in conjunction with the arrow keys.

[0021] For magnetic keys, the use of magnets embedded in the keys, attracted by an iron-containing top plate above the sides of the keys, can provide the user with the feel and stiffness of a traditional computer keyboard keystroke. The keyboard can also provide a physical keystroke confirmation. In certain implementations, the keyboard keys are magnetically biased upwards by electrically conductive pads beneath them, which trigger a keystroke. For the actual keyboard construction, a laminated structure in conjunction with an injection mold can be used, in which the metal is integrated into the plastic. In certain embodiments of the present disclosure, a flexible printed circuit board (FPC) can also be used.Connections to the ribbons may be provided, and a small battery may optionally be inserted into the keyboard to provide limited backup power. In a non-limiting example, the tablet keyboard dimensions are approximately 261.40 mm (X) x 170.16 mm (Y) x 3.30 mm (Z, key surface from top to bottom). Other embodiments of the keyboard may incorporate any suitable dimensions, sizes, and shapes, all of which are encompassed by this disclosure.

[0022] It should be noted that any number of ports (e.g., USB (Universal Serial Bus) ports (e.g., in accordance with the USB 3.0 specification), Thunderbolt™ ports, WiFi ports, a non-standard connection point such as a coupling port, etc.) and multiple antennas can be provided in conjunction with the electronic device 10. [Thunderbolt™ and the Thunderbolt logo are trademarks of Intel Corporation in the U.S. and / or other countries.] The antennas reflect electrical components that can convert electrical current into radio waves. In specific examples, the antennas may be associated with WiFi activities, general wireless connections, small cell deployments, Bluetooth, 802.11, etc.

[0023] In one example embodiment, the mainboard of electronic device 10 is a general-purpose board that can contain various components of the electronic device 10's internal electronic system. These components can include a CPU (central processing unit), memory, and so on. The mainboard can also be connected to one or more ports to accommodate other peripheral devices intended for use by a user of electronic device 10. More specifically, the mainboard can provide the electrical connections through which the other system components can communicate.

[0024] Any processors (including digital signal processors, microprocessors, supporting chipsets, etc.), memory elements, etc., can be suitably coupled to the motherboard based on specific configuration needs, processing requirements, computer designs, etc. Other components, such as external storage, video display controllers, sound controllers, and peripheral devices, can be attached to the motherboard as plug-in cards or via cables, or integrated into the motherboard itself.

[0025] It should be noted that particular embodiments of the present disclosure may easily include a system-on-a-chip (SOC) CPU package. An SOC is an integrated circuit (IC) that integrates components of a computer or other electronic system onto a single chip. It may include digital, analog, mixed-signal, and often radio frequency functions, all of which can be provided on a single-chip substrate.

[0026] In a particular embodiment, the touchpad 18 is a pointing device comprising a touch sensor and a special surface capable of translating the movement and position of a user's fingers into a relative position on the screen. The touchpad 18 can be used instead of a mouse (e.g., when desk space is limited or based on user preference). The touchpad 18 can utilize capacitive sensing, conductivity sensing, or another suitable sensing technology. In a particular embodiment, a suitable battery can be provided near the touchpad 18 to power its operation. Furthermore, either (or both) surface of the display 26 can be a touch display employing one of the technologies discussed herein.

[0027] Briefly referring to Fig. Figure 1B is a simplified schematic representation illustrating a side view of the electronic device 10 in a closed configuration. During operation, when the electronic device 10 is in a closed position, the thin plastic keyboard protects the display. When the display section is folded up into an open position, it operates in a traditional laptop orientation (i.e., a keyboard rests on a surface, with the display held in an upright position). In a particular embodiment, the electronic device 10 incorporates a full-size keyboard with a key spacing of 18.5 mm, providing an optimal touch-typing experience.When the display section is rotated inwards, facing outwards away from the keyboard elements, the device can operate in a tablet configuration, with the keyboard hidden behind the screen and out of the way of user interaction. Its cylindrical hinge mechanism can serve as an ideal grip for the end user. In this mode, the keyboard can be stowed behind the display. The display can still be folded up in tablet mode. In this mode, the keyboard can act as a stand (behind the display), and the device can become a stationary display (e.g., for watching movies). When the display section is detached from the keyboard, it can function on its own as a simple, lightweight tablet.

[0028] In the case where the accessory of the electronic device 10 is a keyboard, the main keyboard components can include various elements. For example, the keyboard can include a keyboard body, which reflects a unibody molded part that may employ insertion and / or joint molding processes to eliminate visible fasteners. Furthermore, the keyboard body can also include overmolded band features to provide stiffness to the outer portion of the recess geometry and to dissipate rotational loads, preventing the upper section 14 from rotating relative to the lower section 16. Additionally, one or more band features are provided that can ensure magnetic attraction of the ferrous disc-shaped features of the tablet.Electrical current can be routed from the tablet to the keyboard to recharge an internal battery or capacitor, or to power a range of components (e.g., Bluetooth). Furthermore, the tablet can be appropriately anchored to the keyboard to prevent a toothed disc feature from rotating relative to the keyboard, while allowing the tablet to rotate concentrically within the recessed area of ​​the keyboard via one or more coupling elements within the tablet.

[0029] For the actual keys, the keys are configured, in a special non-restrictive embodiment, with a 0.5 mm travel distance (for individual keys). Tactile feedback can also be provided (e.g., 70 grams with a "cliff-drop" force deflection feel) to mimic the typing experience of traditional keyboards. In certain implementations, there is little (or no) unused space on the key surface. There can be various types of keys on the keyboard. For example, the keyboard can include floating keys (e.g., left edge: tilde, tab, caps lock, shift, left control; right edge: backspace, backslash, enter, shift), tilt keys, such as the arrow keys, and essentially vertically moving keys, such as function keys and other keys not located along the right or left edge, etc.

[0030] The electronic device 10 can also include an iron-free bridge, which provides sufficient rigidity to the keyboard body. The bridge can guide the keys for their vertical movement, while appropriately restricting their XY movement. Additionally, an iron-containing top plate can increase the keyboard's rigidity, prevent keys from falling out, and attract magnetic keys to provide upward bias.

[0031] Regarding Bluetooth capability, power can reach the radio element by passing current through the bands / socket. The tablet may contain electrically protected (but live) gear discs. The Bluetooth radio board may include a direct current (DC) rectifier to power the electronics regardless of the tablet's orientation (i.e., laptop mode vs. tablet mode, etc.).

[0032] In certain exemplary embodiments, the design of the electronic device 10 may allow a tablet to be connected to the keyboard in both laptop and tablet modes, in addition to a movie stand mode. The viewing angle adjustment range is continuous (e.g., extending from 0° to 125° or 150° or more, or different ranges may be provided). 0° may correspond to the fully closed position, whereas 125° or similar may be defined as fully open. Two socket modules are built into the tablet side of the device, which are magnetically attracted to the interlocking features built into the keyboard. Fig. Figure 1C is a simplified schematic representation illustrating an embodiment of the electronic device 10 in a closed configuration with an attached accessory cover in accordance with an embodiment of the present disclosure.

[0033] Fig. Figure 2 is a simplified schematic representation illustrating an orthographic view of the electronic device 10, divided into two segments. Fig. Figure 3 is a simplified schematic representation illustrating an orthographic view of the electronic device when the two segments are connected.

[0034] In brief, the disc coupling design of the electronic device 10 integrates the coupling element, which is located within the volume of the disc features of the electronic device, and further saves space by incorporating the disc's inclusion elements into the coupling (i.e., a gear). Generally, the design and mounting mechanism allow the tablet disc subassembly to be installed in a slot in the tablet housing that is narrower than the disc subassembly in its installed configuration. The actual disc can be designed with an electrical power connection that is physically isolated from the assembly carrier. Furthermore, the electronic device 10 provides friction coupling integration with a disc gear feature located in the center (or elsewhere) of the disc features within the electronic device (e.g.,for improved range of motion, more compact size, position holding capabilities and better torque transfer characteristics).

[0035] The magnetic strip segments in the accessory (e.g., the keyboard) can attract the ferrous rings of the tablet discs. The central rib (discussed in detail below) provides increased magnetic strength concentrated in the strip. During insertion of the upper section 14 into the lower section 16, the central gear features of the tablet disc, which are connected to the coupling, engage with the tooth in the center of the accessory recess. The central rib of the accessory recess can serve to provide a suitable alignment insertion function. The casing can provide a directed concentration of the magnetic field. In a particular embodiment, a coupling with bidirectional uniform torque characteristics is provided in the disc.This allows the upper section 14 to be inserted into the lower section 16 in any orientation and furthermore provides uniform resistance to movement. This contrasts with a typical standard laptop coupling, which may provide less resistance in one direction or variable resistance based on the angle between the screen and the keyboard.

[0036] Fig. Figure 4 is a simplified orthographic view of a disk groove 40 of the electronic device 10. In this particular embodiment, the disk groove 40 can be in the range of 1.0-3.5 millimeters, although alternative embodiments could have any other suitable dimension. Fig. Figure 5 is a simplified schematic representation illustrating an orthographic view of a potential accessory for the electronic device 10 in accordance with an example implementation. This particular embodiment includes the symmetrical segments 50a-50b, which can provide suitable coupling for a given accessory. For example, an accessory, such as a keyboard, is integrated during attachment so that current can flow between the tablet's disc mechanism and the keyboard, thus powering the Bluetooth radio embedded in the keyboard.

[0037] Fig. Figure 6 is a simplified schematic representation illustrating an orthographic view of an accessory dock 60 of the electronic device 10 in accordance with an embodiment of the present disclosure. The accessory dock 60 can provide a suitable insertion / guiding feature during the connection activities. Fig. Figure 7 is a simplified schematic representation illustrating the underside of the accessory tape components in relation to the electronic device 10. The magnetic components 70 on the opposite side (and installed in the tape) may simultaneously have a suitable lining (e.g., a steel lining) to reduce unwanted stray magnetic fields. Without such a lining, magnetic forces would have an increased likelihood of interacting with other components, altering credit card information, disrupting certain memory elements, etc. The shape of the tape / keyboard and tablet interface may allow the tablet to slide out of the keyboard by using the tablet as a lever to overcome the strong magnetic pull of the connection.The magnetic pull from the keyboard to the tablet can ensure electrical contact and a mechanical connection between the keyboard straps and the tablet. The coupling assembly can be electrically isolated from the tablet and keyboard housings to allow positive and negative connections between the tablet and keyboard, provided by the two couplings. The physical contact of the gear features of the tablet disc elements with the torque transmission tooth of the keyboard straps allows electrical current and / or signals to be transmitted from the tablet to the keyboard. The toothed disc can suitably transmit torque from the keyboard to the tablet. Furthermore, certain embodiments can use a plastic-encased coupling element to electrically isolate the toothed disc from the assembly carrier.

[0038] Fig. Figure 8 is a simplified schematic representation, illustrating an orthographic view of the keyboard electronics and magnetic tapes 80 with the surrounding keyboard housing removed. Fig. Figure 9 illustrates a keyboard housing 90 with the associated keyboard electronics and magnetic tapes removed. Fig. Figure 10 is a simplified schematic representation illustrating a joint assembly 100 in connection with the electronic device 10. Fig. Figures 11-14 are simplified schematic representations illustrating certain joint assembly components 110 / 120 / 130 / 140 in connection with the electronic device 10. The design and mounting mechanism of the electronic device 10 allow the tablet disc to be mounted in a slot that is smaller than the mounted disc. Fig. Figure 15 is a simplified schematic representation illustrating a potential design arrangement 150 in connection with the present disclosure.

[0039] Fig. Figure 16 is a simplified schematic representation illustrating a potential snap-in band configuration 175 in accordance with an embodiment of the present disclosure. In certain exemplary embodiments, the snap-in band can be used on the keyboard to hold the electronic device (e.g., instead of or in conjunction with the use of magnets). In this particular example, a somewhat stiffer central section 171 may be provided, along with a more flexible set of side arms 172 / 173. Furthermore, a disc guide feature 174 is also provided in conjunction with a segment 177, which engages the tablet disc above its center (e.g., for holding purposes). In this particular embodiment, a tooth feature 176 is also provided, which can engage the tablet disc gear for torque transmission.

[0040] In one exemplary embodiment, a three-part snap-in element is used for retention purposes. Power signals can propagate separately through each of the three parts. Alternatively, the power signals can pass through the center section, with the two outer parts acting as insulators. A keyboard-side snap-in element can be designed as a single piece, with slots used to allow independent movement of the outer snap bands and the inner torque grip band / tooth. In other implementations, a one-piece snap-in element can be provided without any separation of the three sections. It should be noted that any suitable plastic, fiber-reinforced plastic, or highly elastic metal (e.g., titanium) can be used in such embodiments.It should also be noted that the one-piece snap-in element, the three-piece snap-in element, and the magnetic holder can all be implemented in the electronic device without a coupling. For example, instead of using a coupling mechanism, the electronic device and the accessory can be held in position at an angle to each other (e.g., by the friction of their corresponding cylindrical mating surfaces).

[0041] Fig. Figure 17 is a simplified schematic representation illustrating a magnetic component 170 in connection with the electronic device 10. In a particular embodiment, the tablet is held on the keyboard by two arc-shaped ferrous steel components, which may be embedded with four linearly polarized segment-shaped magnets. The magnets can attract ferrous steel ring bands that are part of the tablet base modules. Fig. Figure 18 is a simplified schematic representation illustrating a cross-section of a magnet 185 engaged with an iron-containing ring band 180 in connection with the electronic device 10. Fig. Figure 19 is a simplified schematic representation illustrating a cross-section of meshing teeth 190 in conjunction with a magnet of the electronic device 10. In a particular embodiment, the angular adjustment and positional retention can be achieved by the engagement of a single tooth, installed in the keyboard base recess, with the toothed disc.

[0042] Fig. Figure 20 is a simplified schematic representation illustrating a cross-section of the internal features of a tablet disk assembly 200 in association with the electronic device 10. This particular embodiment includes a hardened steel toothed disk 202, a modified REELtorq insert (coupling element) 204, an electrical insulating washer 206, and a torque transmission ring 208. Thus, two REELtorq inserts (coupling elements) can be integrated into the tablet socket design. Alternative embodiments can use other coupling element mechanisms instead of these inserts. The hardened steel toothed disks could be integrated with (e.g., press-fit) the shortened shaft of the torque insert (or appropriately mounted upon it). Furthermore, a custom-molded engineering plastic (e.g.,A polycarbonate (PC) 20% glass fiber (GF) or equivalent body must be provided which protects the torque elements, adapts to the tablet cylinder section and electrically insulates the electrically “live” toothed disc.

[0043] In certain embodiments, the coupling mechanism need not be located inside the device discs (e.g., they may be located in the area shown in certain FIGURES as occupied by batteries). Essentially, any coupling mechanism can be used to implement the teachings of this disclosure. Furthermore, in certain embodiments of this disclosure, the frictional forces need not be equal in both directions.

[0044] For actual assembly, one of the two ferrous steel bands can be mounted using the torque wrench and then inserted into the tablet by pushing it, along with the second ferrous steel band, loosely over the central toothed disc into the middle cylinder section. This toothed disc has a smaller outer diameter than the inner diameter of the ferrous steel band. The connecting subassembly can then be pressed in from the outside through the outer section of the tablet cylinder, and the second ferrous steel band can be secured to it.

[0045] Fig. Figure 21 is a simplified schematic representation illustrating a potential battery configuration 210 in connection with the electronic device 10. Battery cells housed within the tablet cylinder can (via protective circuits) supply power to the toothed discs connected to (and powering) the Bluetooth keyboard. Fig. Figure 22 is a simplified schematic representation illustrating overmolded tapes with engagement features and a tape magnet assembly (generally shown at Figure 220) in association with the electronic device 10. In this particular embodiment, a Bluetooth radio module is illustrated in conjunction with a tape, a tape magnet, and three tape support carriers. The Fig. The 22 bands shown can accommodate rare-earth magnets that attract the disks in the tablet. The bands can be made of low-carbon steel, which helps reduce stray magnetic fields radiated from the underside of the keyboard. Three band support carriers can extend through the keyboard wall and, according to one embodiment of the present disclosure, be pressed into each band. This can mechanically connect the bands to the keyboard and / or serve to conduct electrical current or signals from the bands to the internal region (circuits) of the keyboard. The band and the band magnet assembly can also be injection-molded into the plastic keyboard body, which helps to support the outer tip of the keyboard body.

[0046] The band support brackets can conduct power from the tablet through the band and to the Bluetooth radio module. Since the discs in the tablet have an electrical polarity and can be inserted into the keyboard in multiple orientations, a DC rectifier can be used on the Bluetooth radio module. The band support brackets can also anchor the bands to aid in the transmission and distribution of loads to the keyboard. A single central tooth on the band can engage with the toothed disc in the tablet to prevent unwanted rotation of the toothed disc relative to the keyboard and further allow the tablet to be inserted into the keyboard in either orientation.Since the ribbons touch the electrically live toothed discs of the tablet, the ribbons can become electrically charged, so they need to be electrically insulated from other metal components of the keyboard; however, proper keyboard and tablet electronic circuit design can also be used to eliminate this need.

[0047] In certain embodiments, instead of routing power signals through the gear, certain configurations can route power signals through one or more disks with wiper contacts on the accessory side. Other configurations can route power signals through disk features that are not necessarily the ferrous features shown; rather, a different metal ring could be used as a contact. In still other examples, power signals can be routed through a plug-in connector (e.g., its plug end is integrated into the keyboard side and its socket end is integrated into the electronic device). This could effectively establish the electrical connection and furthermore, it could be used as the sole torque transmission point between the keyboard and the tablet.It should be noted that such an embodiment is like an enlarged version of the tooth that engages with the gear. This is not necessarily ideal, as it may only allow the tablet and keyboard (or other accessory) to be connected when they are in a specific orientation. Virtually any other electrical connection method could be used, and thus these are clearly within the scope of the present disclosure. Furthermore, alternative designs for the cylinder and the recess (which meet at the joint) could be used without departing from the teachings of the present disclosure.

[0048] Although potentially cumbersome, such configurations represent feasible alternative embodiments of the present disclosure.

[0049] Fig. Figure 23 is a simplified schematic representation illustrating a locking magnet 230 in association with the electronic device 10, which has a touchpad section 232. In a particular example implementation, rare-earth magnets with alternating polarity and a steel backplate are used to reduce magnetic stray fields through the underside of the keyboard and to further concentrate the magnetic fields towards the tablet. For example, suitable magnets can be placed under the surface shown in Figure 23. Fig. Figure 23 shows that three rare-earth magnets with alternating polarity are installed in the wrist rest. The locking magnets can attract an associated magnet / snap-in plate combination installed in the tablet. The steel backplate in the keyboard can concentrate the magnetic fields from the locking magnets and direct them upwards, towards the tablet, to keep the device closed. The locking magnet can be designed to have the same locking force when the device is in laptop mode and in nested tablet mode.
