[0025] Those skilled in the art will recognize and understand that, according to common practice, the various features of the drawings discussed below are not necessarily drawn to scale and that the sizes of the various features and elements of the drawings may be exaggerated or reduced in order to more clearly illustrate the embodiments of the invention described herein. DETAILED DESCRIPTION

[0026] Reference will now be made specifically to the representative embodiments shown in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover alternatives, modifications and equivalent forms that may be included in the spirit and scope of the embodiments defined by the appended claims.

[0027] In the following detailed description, reference is made to the accompanying drawings which form a part of the specification and in which are shown by way of illustration specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, it is to be understood that these examples are not limiting and other embodiments may be used and changes may be made without departing from the spirit and scope of the described embodiments.

[0028] The following disclosure relates to an accessory device suitable for use with an electronic device, such as a mobile wireless communication device (smartphone and tablet device). In addition to providing a protective cover, the accessory device described herein can support and orient the electronic device and enable the electronic device to be accessed by a user. The accessory device described herein may include multiple sections, such as a first section (or cover section) and a second section (or keyboard / input section) that are rotationally coupled together by one or more hinge assemblies. The first section includes several segments, at least some of which include magnets designed to magnetically couple with magnets in the electronic device. The second section includes an input mechanism (e.g., a keyboard, a trackpad) that allows a user to interact with the electronic device. Unlike conventional accessory devices, the accessory device described herein can hold / suspend an electronic device, thereby allowing the electronic device to "float" or hover a portion of the electronic device. For example, using a hinge assembly, a segment of the first section can hold and suspend the electronic device above the second section without the electronic device contacting the second section, thereby allowing the user to view the electronic device and interact with the input mechanism to control the electronic device.

[0029] The hinge assembly provides sufficient friction so that the first section can remain in a fixed position while holding and suspending the electronic device against gravity. This feature of the accessory device provides several advantages. For example, the keyboard and the electronic device remain sufficiently spaced apart, thereby increasing the flexibility of the design / layout of the electronic device relative to the keyboard, and vice versa. In addition, based on the "floating" nature of the electronic device, the accessory device can position the electronic device at least partially above the keyboard while still allowing the user to interact with the keys positioned below the electronic device. In addition, in order to prevent excessive rotation and tipping of the electronic device, the hinge assembly can be combined with an integrated stop mechanism that limits the section and, in turn, limits the movement of the electronic device.

[0030] The hinge assemblies of the accessory devices described herein can provide additional functionality. For example, in addition to limiting the movement of the segments and providing friction that enables the segments to hold the electronic device in a fixed position (against gravity), some hinge assemblies can provide a path for wiring that is guided through the segments. In this regard, the accessory devices described herein may include electrical contacts designed to establish communication between the electronic device and the accessory device. In addition, the accessory devices described herein may include a port for receiving a connector from an external power source. Using the electrical contacts, the accessory devices described herein can relay electrical energy from the external power source to the electronic device and charge one or more batteries of the electronic device.

[0031] References below Figures 1 to 16 However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these drawings is for illustrative purposes only and should not be construed as limiting.

[0032] Figure 1 An isometric view of an accessory device 100 according to some of the described embodiments is shown. As a non-limiting example, the accessory device 100 may be referred to as a cover, a protective cover, or a folio. As shown, the accessory device 100 includes a section 102a and a section 102b. Section 102b is designed to move relative to section 102a (i.e., rotate), and vice versa. Sections 102a and 102b may be referred to as a first section and a second section, respectively. However, "first" and "second" may be used interchangeably. In addition, sections 102a and 102b may be referred to as a keyboard section and a cover section, respectively. Section 102a may include an input mechanism 104a and an input mechanism 104b. As shown, input mechanism 104a includes a keyboard, and input mechanism 104b includes a touchpad or a touch pad.

[0033] Section 102b may include multiple sections. For example, section 102b includes section 106a and section 106b. Section 106a is designed to move relative to section 106b (i.e., rotate), and vice versa. Sections 106a and 106b may be referred to as first and second sections, respectively. However, "first" and "second" may be used interchangeably.

[0034] Section 102b may include several magnets embedded in sections 106a and 106b. For example, section 102b includes magnet 108a, magnet 108b, magnet 108c, magnet 108d, and magnet 108e located in section 106a. Section 102b also includes magnet 108f, magnet 108g, and magnet 108h located in section 106b. In addition, section 102a includes magnet 108i and magnet 108j. It should be noted that each of the aforementioned magnets is represented by a rectangular perimeter. However, in some cases, the rectangular perimeter represents several discrete magnetic elements. At least some of the aforementioned magnets are designed to be used with electronic devices ( Figure 1 102a). In this way, the accessory device 100 can hold / fix the electronic device to the section 102b. In addition, even when the weight of the electronic device and the effects of gravity are taken into account, the magnets located in the section 106a can provide a magnetic field sufficient to hold / fix the electronic device and suspend the electronic device above the section 102a. In addition, at least some of the aforementioned magnets provide a magnetic field that can be detected by the sensor of the electronic device, where the detection is used as logic to determine the relationship between the accessory device 100 and the electronic device. This will be discussed further below.

[0035] In addition, section 102b may include an opening 109 or through hole formed in section 106a. In this way, when the electronic device is fixed with section 102b, the camera assembly and / or flash module included in the electronic device will not be covered by section 102b. Although opening 109 is shown as being at a specific location on section 106a, opening 109 may be located anywhere on section 106a corresponding to the location of the camera assembly and flash module on the electronic device.

[0036] The accessory device 100 may also include electrical contacts 110 located on the section 106a. In this regard, when the electronic device is fixed together with the section 102b, the accessory device 100 may use the electrical contacts 110 to form a communication channel with the electronic device. Thus, the user may use the input mechanism 104a to provide input or commands in the form of keystrokes to the electronic device, and the user may use the input mechanism 104b to provide input in the form of gestures and / or presses (i.e., clicks) the input mechanism 104b to the electronic device. Although the electrical contacts 110 are shown as being at a specific position on the section 106a, the electrical contacts 110 may be located anywhere on the section 106a corresponding to the position of the electrical contacts on the electronic device. In addition, although the electrical contacts 110 show three electrical contacts, in other embodiments, the electrical contacts 110 may vary. Specifically, the electrical contacts 110 may include a number of contacts corresponding to the number of electrical contacts located on the electronic device.

[0037] The accessory device 100 may also include a port 112. The port 112 may include a cable connector ( Figure 1 As a non-limiting example, port 112 may be designed for an industry standard, such as a Universal Serial Bus ("USB") or USB-C. However, other industry standards are possible. In addition, port 112 may be connected to a wireless communication interface via a cable or flexible circuit ( Figure 1 The accessory device 100 can thus receive power through the port 112 and provide power to an electronic device that is in electrical communication with the electrical contacts 110. The power can be used to charge one or more batteries of the electronic device. In addition, although the port 112 is described as a device for providing power to the electronic device, in some embodiments, the port 112 is also used for connecting the electronic device to an external data source ( Figure 1 Thus, in some embodiments, port 112 is used for bidirectional data transmission between accessory device 100 and the aforementioned external data sources. In addition, it should be noted that accessory device 100 delivers direct current ("DC") through electrical contacts 110. In this regard, accessory device 100 does not provide relatively high voltage or high current through electrical contacts 110, and therefore electrical contacts 110 are safe for human contact.

[0038] To facilitate relative rotational movement between sections 102a and 102b, accessory device 100 may include a plurality of cylindrical members. For example, accessory device 100 includes cylindrical member 114a coupled to section 102a and cylindrical member 114b coupled to section 102b. Each of cylindrical members 114a and 114b may define a generally hollow tube or shaft, thereby providing a conduit for other components. In this regard, accessory device 100 may integrate a hinge assembly (including a coupling mechanism and a spring mechanism) within cylindrical members 114a and 114b. This will be further shown and described below.

[0039] As a non-limiting example, the cylindrical members 114a and 114b may include a metal, such as aluminum (including anodized aluminum). Therefore, the cylindrical members 114a and 114b may provide a rigid component that provides protection for the accessory device 100 in the event that the accessory device 100 falls and absorbs significant force. However, in the event that the accessory device 100 falls while carrying an electronic device, in order to protect the electronic device from being damaged by contact with the cylindrical members 114a and 114b, the accessory device 100 may include non-metallic parts 116a and non-metallic parts 116b. The non-metallic parts 116a and 116b may prevent metal-to-metal contact between the electronic device housing and the cylindrical members 114a and 114b. In addition, the non-metallic parts 116a and 116b may serve as shock absorbers. As a non-limiting example, the non-metallic parts 116a and 116b may be constructed of one or more materials, including rubber, plastic, and / or fabric.

[0040] In order to cover and hide certain internal features and components, the accessory device 100 may include multiple covers. For example, the accessory device 100 includes a cover 118a located on section 102a, and a cover 118b located on section 102b (such that sections 106a and 106b are covered by cover 118b). Covers 118a and 118b generally cover one area of ​​the accessory device 100 (e.g., the front area). In this regard, the accessory device 100 may also include a cover 118c, which generally covers another area of ​​the accessory device 100 (e.g., the back area). In some embodiments, the aforementioned covers include silicone and / or fabric. Figure 1 In the illustrated embodiment, the aforementioned cover comprises polytrimethylene terephthalate ("PTP") and thermoplastic polyurethane ("TPU") laminated together. The TPU layer can provide a structural rigidity layer, while the PTP layer provides an aesthetic exterior finish.

[0041] While the aforementioned covers substantially cover areas of the accessory device 100, these covers may include openings to accommodate certain features. For example, cover 118a includes openings for the keys of input mechanism 104a, and openings for input mechanism 104b. With respect to the former, the openings of cover 118a may define a web through which the keys of input mechanism 104a pass. Furthermore, the two input mechanisms 104a and 104b may be sub-flush, or lower in height, relative to cover 118a. Additionally, covers 118b and 118c generally do not cover opening 109.

[0042] The accessory device 100 may also include a counterweight 120a and a counterweight 120b. When an electronic device is secured to the accessory device 100, for example, at section 106a, the center of mass of the system (i.e., the accessory device 100 plus the electronic device) may make the system susceptible to tipping over or falling over. Additionally, the forces provided by the user's interaction with the electronic device may also cause the accessory device 100 to tip over or fall over. However, the counterweights 120a and 120b are designed to counteract these effects caused by the accessory device 100 carrying the electronic device. This will be further illustrated below.

[0043] Figure 2 Shows Figure 1 An isometric view of accessory device 100 is shown, illustrating an electronic device 200 that can be used with accessory device 100. Electronic device 200 may include a portable electronic device, such as a mobile wireless communication device (e.g., a smartphone, a tablet device). As a non-limiting example, electronic device 200 may include a housing 202 or casing designed to carry several components (not shown), such as processing circuitry (e.g., a central processing unit, a graphics processing unit, an application specific integrated circuit), memory circuitry, a battery, an audio speaker, a microphone, and a flexible circuit to electrically couple the components together. Electronic device 200 may also include a display assembly 204 coupled to housing 202. Display assembly 204 may include a touch input display.

[0044] The electronic device 200 may also include magnets designed to magnetically couple with magnets in the accessory device 100. For example, the electronic device 200 includes magnet 208a, magnet 208b, magnet 208c, magnet 208d, and magnet 208e designed to magnetically couple with magnets 108a, 108b, 108c, 108d, and 108e located in section 106a, respectively. In addition, the electronic device 200 includes magnet 208f and magnet 208g, which are designed to magnetically couple with magnets 108f and 108g located in section 106b, respectively. In addition, the electronic device 200 includes magnet 208i, which is designed to magnetically couple with magnet 108i located in section 102a. Figure 2 In the state of accessory device 100 shown, magnets 208f, 208g, and 208i are not magnetically coupled to magnets 108f, 108g, and 108i, respectively. However, in other states (as shown and described below), magnets 208f, 208g, and 208i are magnetically coupled to magnets 108f, 108g, and 108i, respectively. Additionally, similar to the magnets of accessory device 100, the magnets of electronic device 200 are represented by a rectangular perimeter, which may represent a number of discrete magnetic elements or a single magnetic element.

[0045] The electronic device 200 also includes electrical contacts 210 designed to electrically couple with the electrical contacts 110 of the accessory device 100, thereby enabling the electronic device 200 to communicate with the accessory device 100. The electronic device 200 also includes a sensor 220a and a sensor 220b. In some embodiments, the sensors 220a and 220b each include a magnetic field sensor, such as a Hall effect sensor (as a non-limiting example). The sensors 220a and 220b are designed to detect at least some of the magnets located in the accessory device 100. For example, magnet 108h is positioned at a location such that sensor 220a can detect the magnetic field generated by magnet 108h, and magnet 108j is positioned at a location such that sensor 220b can detect the magnetic field generated by magnet 108j. Figure 2 In the state of the accessory device 100 shown, the corresponding magnetic fields generated by the magnets 108h and 108j are not detectable by the sensors 220a and 220b, respectively. However, in other states (as shown and described below), the corresponding magnetic fields generated by the magnets 108h and 108j are detectable by the sensors 220a and 220b, respectively.

[0046] The electronic device 200 may include a camera assembly 222 and a flash module 224. The opening 109 in the accessory device 100 is sized and positioned so that the camera assembly 222 and the flash module 224 are not obstructed by the section 106a.

[0047] Figure 3 Shows Figure 1 FIG. 1 is a plan view of the accessory device 100 showing various components of the section 102 b. For purposes of illustration, the cover 118 b (eg, Figure 1 106a and 106b of section 102b. For example, as shown in the enlarged view, section 102b includes hinge 126a and hinge 126b. Although hinges 126a and 126b allow some relative rotational movement of sections 106a and 106b, hinges 126a and 126b may also limit or control the movement of section 106a relative to section 106b. For example, section 106a may rotate relative to section 106b to a predetermined angle based on the configuration and construction of hinges 126a and 126b. Therefore, each of hinges 126a and 126b may be referred to as a stop hinge.

[0048] Section 102b also includes hinge 128a and hinge 128b. Hinge 128a and 128b may include a number of friction elements (shown, not labeled) that are frictionally engaged with each other. In this way, the friction force provided by hinge 128a and 128b can keep section 106a initially in a fixed position relative to section 106b. However, once a rotational force that overcomes the friction force provided by hinge 128a and 128b is applied to section 106a, section 106a can rotate relative to section 106b, provided that a predetermined angle based on hinge 126a and 126b has not yet been reached between sections 106a and 106b. In addition, once the applied force drops below the friction force provided by hinge 128a and 128b, section 106a remains in a subsequent fixed position relative to section 106b. Therefore, each of hinge 128a and 128b can be referred to as a friction hinge. More details about hinges 128a and hinges 128b and their corresponding friction elements can be found in, for example, U.S. patent application serial number 16 / 041,633, entitled HINGE ASSEMBLY WITH LAYERED FRICTION ELEMENTS, which is incorporated herein by reference in its entirety. In addition, the functions and features of hinges 126a and 126b and hinges 128a and 128b will be further shown and described below.

[0049] Section 102b also includes hinges 130a and 130b. In addition to facilitating rotational movement between sections 106a and 106b, hinges 130a and 130b also define conduits for wiring. As shown, wires 132a and 132b (each representing one or more wires) pass through hinges 130a and 130b, respectively, including hinge 130a and the corresponding cylinder of hinge 130a. Wires 132a and 132b are used to electrically couple electrical contacts 110 to port 112. In addition, wires 132a and 132b can also be used to electrically couple electrical contacts 110 to input mechanisms 104a and 104b (both of which are in Figure 1 Section 102b also includes hinges 133a and 133b, each of which can assist / facilitate rotation of section 106a relative to section 106b.

[0050] In order to rotationally couple the section 102a with the section 102b, the accessory device 100 also includes a hinge assembly. For example, the accessory device 100 includes a hinge assembly 134a and a hinge assembly 134b. The hinge assemblies 134a and 134b are each connected to the cylindrical members 114a and 114b. More details of the hinge assemblies 134a and 134b will be discussed below.

[0051] Figure 4 Shows Figure 3134a. As shown in the figure, the hinge assembly 134a includes a coupling mechanism 136 and a spring mechanism 138. The coupling mechanism 136 (or simply the coupling) includes a spring mechanism 138 designed to engage the cylindrical member 114b (such as Figure 3 The coupling mechanism 136 further includes a rotation mechanism 144 coupled to the shaft 142a. As shown in the enlarged view, the rotation mechanism 144 engages with the part 148, and in particular, engages with the surface 150a of 148. In response to the rotation of the section 102b relative to the section 102a (both in Figure 1 148 ), the rotating mechanism 144 may rotate relative to 148 in the direction indicated by arrow 149 (together with shaft 142a). The rotating mechanism 144 may continue to rotate until surface 152 of the rotating mechanism 144 engages surface 150b of part 148. When surfaces 152 and 150b engage each other, further rotation of the rotating mechanism 144 is prevented, and further rotational movement of the sector 102b relative to the sector 102a is also prevented. However, the rotating mechanism 144 may rotate in the opposite direction (i.e., the direction opposite to arrow 149) until the rotating mechanism 144 again engages surface 150a, thereby preventing the sector 102b from rotating in the opposite direction relative to the sector 102a. Therefore, the coupling mechanism 136 can provide a stop mechanism for limiting the movement of the sector 102b relative to the sector 102a in two different directions. This will be discussed further below.

[0052] The coupling mechanism 136 also includes a friction mechanism 146 that frictionally engages the shaft 142a. The frictional engagement between the friction mechanism 146 and the shaft 142a can provide a friction force sufficient to maintain a fixed position between the sections 102a and 102b, even when the rotation mechanism 144 is not engaged with either of the surfaces 150a and 150b of the part 148. Thus, the coupling mechanism 136 provides a friction force to maintain the section 102b in a fixed position relative to the section 102a, such as Figure 1 In addition, the coupling mechanism 136 may include several stops located on the periphery of the part 148. For example, the coupling mechanism 136 includes a stop 154a and a stop 154b (representing additional stops) located on the outer surface of the part 148. When the user rotates the section 102b relative to the section 102a, and in particular, when the accessory device 100 ( Figure 1 When the rotatable device 154a and 154b is changed from the closed state to the open state or vice versa (as shown in FIG. 1 ), the stoppers 154a and 154b can provide an indication of the rotational movement to the user. The open state and the closed state will be shown and described below.

[0053] The coupling mechanism 136 also includes a shaft 142b. In some embodiments, shafts 142a and 142b define an integral (i.e., one-piece or monolithic) shaft. Therefore, in these embodiments, shafts 142a and 142b represent the opposite ends of a single shaft. In other embodiments, shafts 142a and 142b are separate bodies.

[0054] The spring mechanism 138 is designed to be Figure 2 102b) is magnetically coupled to the section 102b to balance the weight of the electronic device 200. In this regard, the spring mechanism 138 can prevent the section 102b from rotating and collapsing due to the weight of the electronic device 200. Therefore, the spring constant of the spring mechanism 138 can be selected based on the weight of the electronic device 200 and the section 102b. In order to couple with the coupling mechanism 136, the spring mechanism 138 includes an opening 156 that receives the shaft 142b. The spring mechanism 138 also includes a spring member 156 that is designed to be coupled to the cylindrical member 114a (such as Figure 3 14. The spring end 158 is coupled to the housing 100 (shown).

[0055] For example, the rotation of segment 102b relative to segment 102a (both at Figure 1 142a). The rotation of shaft 142a causes a corresponding rotation of rotation mechanism 144. The rotation of rotation mechanism 144 causes a corresponding rotation of shaft 142b, which provides a rotational force to spring mechanism 138. The rotation of the components can continue until rotation mechanism 144 engages a surface of part 148 (i.e., surface 150a or surface 150b). In addition, friction mechanism 146 provides frictional engagement with (at least) shaft 142a, and thus, when rotation stops, section 102b can be maintained in a fixed position relative to section 102a. Hinge assembly 134b ( Figure 3 ) may include any of the components and features shown and described with respect to hinge assembly 134a.

[0056] Figure 5 An isometric view of cylindrical members 114a and 114b is shown. As shown, cylindrical member 114a includes an opening 158a on a rounded or curved surface of cylindrical member 114a. In addition, cylindrical member 114a includes a diameter 160a, and cylindrical member 114b includes a diameter 160b that is smaller than diameter 160a. Based on the opening 158a of cylindrical member 114a and the corresponding diameters of cylindrical members 114a and 114b, cylindrical member 114b can be assembled into cylindrical member 114a. In addition, based on the corresponding positional relationship of cylindrical members 114a and 114b, cylindrical members 114a and 114b can be respectively referred to as an outer cylindrical member and an inner cylindrical member.

[0057] The cylindrical member 114a may include additional openings along with the cylindrical member 114b. For example, the cylindrical member 114a includes the opening 158b, and the cylindrical member 114b includes the opening 162a. The openings 162a and 158b allow for wiring, such as the wires 132a and 132b (eg, Figure 3 158c and 162b, respectively, which are designed to receive the hinge assembly 134a (as shown). Figure 3 In addition, the cylindrical members 114a and 114b include openings 158d and 162c, respectively, which are designed to receive the hinge assembly 134b (as shown). Figure 3 shown).

[0058] As shown, cylindrical members 114a and 114b are connected to plates 164a (partially shown) and 164b, respectively. Plates 164a and 164b may be connected to sections 102a and 102b, respectively (both at Figure 1 When the cylindrical members 114a and 114b are connected with the hinge assemblies 134a and 134b (as shown in Figure 3 When assembled together (as shown), the cylindrical members 114a and 114b can define a hinge assembly for rotationally driving the segment 102b relative to the segment 102a.

[0059] Figure 6 Shows Figure 5 6-6 of the cylindrical member 114a shown in FIG. As shown, the cylindrical member 114a includes a circular protrusion 166a, a circular protrusion 166b, and a circular protrusion 166c. Each of the circular protrusions 166a, 166b, and 166c defines an undercut in the cylindrical member 114a. The cylindrical member 114a is designed to be a spring mechanism (similar to Figure 3 The spring mechanism 138 shown in FIG. 1 is assembled into an opening 168 defined in part by circular protrusions 166a, 166b, and 166c. In addition, the cylindrical member 114a can receive a part 170 designed to couple with the aforementioned spring mechanism. Part 170 includes a spring end (similar to Figure 3 The recessed portion 172 of the spring end 158 is shown.

[0060] The feature 170 can be used to rotate and thereby preload the spring mechanism and drive the spring mechanism further into the opening 168 of the cylindrical member 114a. For example, Figure 7 Shows Figure 5 A cross-sectional view of the cylindrical member 114a is shown taken along line 7-7. Figure 7 Representation and Figure 6The positions of the openings 168 shown are compared to different positions of the openings 168. For example, in Figure 7 At the location of the opening 168 shown, the cylindrical member 114a includes a circular protrusion 172a, a circular protrusion 172b and a circular protrusion 172c, which are similar to the circular protrusions 166a, 166b and 166c, respectively (each at Figure 6 166a, 166b, 166c, respectively. Once the spring mechanism is rotated, the spring mechanism is driven into the opening 168 by the part 170, wherein the spring member is surrounded by the circular protrusions 172a, 172b, 172c, and in some cases is positioned against the circular protrusions 172a, 172b, 172c.

[0061] Figures 8 to 13 Various states of the accessory device 100 and associated relationships with the electronic device 200 based on the states of the accessory device 100 are shown and described.

[0062] Figure 8 A side view of the accessory device 100 and the electronic device 200 is shown, showing the accessory device 100 in a closed state. As shown, the accessory device 100 wraps around the electronic device 200, thereby covering multiple surfaces of the electronic device 200. In addition, the accessory device 100 is coupled to the electronic device 200 via magnets. For example, the magnets 108a, 108b, 108f, and 108i of the accessory device 100 are magnetically coupled to the magnets 208a, 208b, 208f, and 208i of the electronic device 200, respectively. Although not shown, additional magnetic couplings may also be present.

[0063] In addition, in the closed state, sensors 220a and 220b can detect magnetic fields from magnets 108h and 108j, respectively, and provide signals based on the detection of the magnetic fields. Electronic device 200 can determine that accessory device 100 is in the closed state based on input signals received by sensors 220a and 220b indicating that the corresponding magnetic fields from magnets 108h and 108j are detected, respectively. Therefore, electronic device 200 can determine that display assembly 204 is covered by accessory device 100 and place display assembly 204 in an inactive state. In the inactive state, display assembly 204 is turned off.

[0064] Fig. 9A side view of the accessory device 100 and the electronic device 200 in another orientation is shown, showing the accessory device 100 in a closed state. Based on the orientation of the accessory device 100 and the electronic device 200, gravity is in the direction of arrow 174. In the event that the system (defined by the accessory device 100 and the electronic device 200) is dropped, the non-metallic part 116a is positioned between the electronic device 200 and the cylindrical member 114a. Thus, the non-metallic part 116a prevents collision between the electronic device 200 and the cylindrical member 114a, thereby preventing damage to the electronic device 200. The non-metallic part 116b ( Figure 1 ) is positioned in a manner similar to that described for the non-metallic part 116a, and thus provides similar benefits as the non-metallic part 116a.

[0065] Fig.10 1 and 2 are side views of the accessory device 100 and the electronic device 200, showing the accessory device in a partially open state. In the partially open state, the section 102b is rotated away from the section 102a by an angle α. The angle α may represent the maximum angle between the sections 102b and 102a because the hinge assemblies 134a and 134b (eg, Figure 3 102a) limits the further rotational movement of the section 102b away from the section 102a. Specifically, the relationship between the rotating mechanism 144 and the part 148 (as shown in FIG. Figure 3 As shown) can determine / limit the angle α.

[0066] Fig.11 An isometric view of the accessory device 100 and the electronic device 200 is shown, showing the accessory device 100 in a partially open state and the display assembly 204 of the electronic device 200 in an inactive state. Figure 8 and Fig. 9 ) to a partially open state ( Fig.11 ), the display assembly 204 remains in an inactive state. In this regard, see again Fig.10 , in the partially open state, sensor 220b no longer detects the magnetic field from magnet 108j. However, sensor 220a can still detect the magnetic field from magnet 108h. Therefore, display assembly 204 is in an inactive state because sensor 220a provides input based on detecting the magnetic field from magnet 108h.

[0067] Fig.12 1 and 2 show a side view of the accessory device 100 and the electronic device 200, which shows the accessory device 100 in an open state. As shown, the section 106a is opened from its partially opened state (eg, Fig.10The angle β may represent the maximum rotation angle of the segment 106a because the hinges 126a and 126b ( Figure 3 ) limits further rotational movement of segment 106a. Therefore, the design and configuration of hinges 126a and 126b can determine / limit the angle β. Figure 3 128a and 128b), segment 106a can be held in a fixed position, i.e., at an angle β. Still, based on the friction provided by hinges 128a and 128b, segment 106a can rotate relative to segment 106b at an angle less than angle β and be held in a fixed position at that angle (less than angle β).

[0068] Generally, the accessory device 100 is designed so that the section 102b rotates to the angle α before the section 106a rotates. This is based in part on the hinges 128a and 128b and the hinge assemblies 134a and 134b (all in Figure 3 In addition, in the partially open state (as shown in Fig.10 and Fig.11 ), the magnet 108f in the accessory device 100 remains magnetically coupled to the magnet 208f in the electronic device 200. The resulting magnetic attraction holds the electronic device 200 against the segments 106a and 106b, thereby preventing the segment 106a from rotating. Fig.12 As shown, when section 102a is separated from section 102b by angle α, the additional rotational force applied to section 106a may overcome the magnetic attraction between magnets 108f and 208f, thereby causing section 106a to rotate and electronic device 200 to decouple from section 106b.

[0069] In addition, when the area 102b (specifically, as Fig.12 102a. When the segment 106b shown in FIG. 106a is separated from the segment 102a by an angle α and the segment 106a is rotated to an angle β, the electronic device 200 is separated from the segment 102a by an angle γ. Angle γ is the sum of angles α and β, and represents the maximum angle between the segment 102b (and specifically, the segment 106a) and the segment 102a. In other words, angle γ represents the maximum angle between the electronic device 200 and the segment 102a. Angle γ may be approximately in the range of 110 to 150 degrees. In some embodiments, angle γ is 135 degrees. In addition, angle α may be approximately in the range of 40 to 80 degrees, and angle β may be approximately in the range of 30 to 70 degrees, as long as the sum of angle α and angle β is at or within a given range of angle γ.

[0070] Additionally, in the open state, the electronic device 200 is no longer engaged with the section 106b. In other words, the electronic device 200 is only engaged with the section 106a in the open state. Although the magnet 108f in the accessory device 100 is no longer magnetically coupled with the magnet 208f in the electronic device 200, the magnetic coupling between the several magnets in the accessory device 100 (i.e., the magnets in the section 106a) and the magnets in the electronic device 200 may provide sufficient magnetic force to hold the electronic device 200 against the section 106a. Furthermore, the magnetic coupling between the magnets in the accessory device 100 and the electronic device 200 provides sufficient magnetic force to suspend the electronic device 200 above the section 102a such that the electronic device 200 is not in contact with the section 102a, as shown in FIG. Fig.12 shown.

[0071] Additionally, as shown in the enlarged view, the cover 118c is at least partially disengaged from the sections 106a and 106b. In this position, the cover 118c is not bonded (e.g., by an adhesive) to the sections 106a and 106b. Thus, in the open state of the accessory device 100, the cover 118c is free to at least partially move away from the sections 106a and 106b to avoid unwanted flexing and to avoid unwanted reaction forces of the cover 118c that would otherwise counteract the hinge ( Figure 3 shown).

[0072] Fig.13 An isometric view of the accessory device 100 and the electronic device 200 is shown, showing that the accessory device 100 is in an open state and the display assembly 204 of the electronic device 200 is in an active state. In the open state, the sensors 220a and 220b no longer detect the magnetic field from the magnets 108h and 108j, respectively. Therefore, the electronic device 200 uses the input information (or no input information) from the sensors 220a and 220b indicating that the magnetic field is not detected to activate the display assembly 204, that is, turn on the display assembly 204, such as Fig.13 shown.

[0073] Thus, when the accessory device 100 is opened from the partially opened state ( Fig.10 and Fig.11 ) to the open state ( Fig.13 ), the electronic device 200 activates the display assembly 204. In addition, when the accessory device 100 transitions from the open state back to the partially open state, the display assembly 204 can remain activated. However, when the accessory device 100 transitions from the partially open state to the closed state ( Figure 8 and Fig. 9108h and 108j, respectively, and provide input information indicating the detection of the magnetic field to the electronic device 200. In addition, the weights 120a and 120b located in the section 102a of the accessory device 100 can prevent the system (i.e., the accessory device 100 plus the electronic device 200) from tipping over due to the weight and position of the electronic device 200 and / or due to user interaction with the display assembly 204.

[0074] Fig.14 An isometric view of the accessory device 100 is shown showing the cover 118a removed from the section 102a to reveal additional features. As shown, the accessory device 100 includes a circuit board 176. Several components such as processing circuits and memory circuits can be located on the circuit board 176. In addition, the circuit board 176 can be connected to the circuit board 176 by, for example, connectors and / or flexible circuits ( Fig.14 104a and 104b. In addition, the circuit board 176 is electrically coupled to the electrical contacts 110 ( Figure 1 The circuit board 176 is designed to be coupled to the aforementioned components and to the electronic device ( Fig.14 (not shown) communications.

[0075] To enhance structural rigidity, the section 102a may include a large amount of metal, such as aluminum. For example, the section 102a includes a metal section 178a, a metal section 178b, and a metal section 178c. In addition, the input mechanism 104a may be made of a metal plate ( Fig.14 Although the overall structural rigidity may be increased (compared to the use of non-metal), the metal may hinder or block the electronic device ( Fig.14 For example, in the closed state (not shown) of the accessory device 100, the Figure 8 As shown in , the region 102 a substantially covers one surface of the electronic device 200 , and the aforementioned metal is sufficiently close to the electronic device 200 .

[0076] To modify the accessory device 100 to enhance / enable RF transmission, the section 102a may include a plurality of non-metallic sections. Fig.14 As shown, the section 102a includes a non-metallic section 182a and a non-metallic section 182b. As a non-limiting example, the non-metallic sections 182a and 182b may be formed of a rigid plastic that does not generally block or hinder RF transmission. Based on the corresponding position of the RF transmission component (e.g., the antenna) in the electronic device, especially when the accessory device 100 holds the electronic device 200 in a closed state ( Figure 8The positions of the non-metallic regions 182a and 182b are selected based on the corresponding positions of the non-metallic regions 182a and 182b as shown in FIG.

[0077] In addition, the section 102a may include a light source 184 that is designed to emit light toward the input mechanism 104a. The light source 184 may include one or more light emitting diodes (LEDs). When the input mechanism 104a includes a keyboard having a plurality of keys, the keys may be illuminated based on the light provided by the light source 184. In addition, in order to control the light source 184, the circuit board 176 is electrically coupled to the light source 184. In this regard, the circuit board 176 may include control circuitry for activating and deactivating the light source 184.

[0078] Fig.15 An isometric view of the input mechanism 104b is shown, showing additional features of the input mechanism 104b. The underside / bottom of the input mechanism 104b is shown. The input mechanism 104b includes a plate 186 covering a center location 188 of the input mechanism 104b and each corner of the input mechanism 104b. Using the plate 186, a user can generally press the user input surface ( Fig.15 18a), i.e., the touch surface of the input mechanism 104b, and a "click" feeling is experienced based on the pressing. In addition, the integration of the plate 186 can provide a relatively more compact and thin version of the input mechanism 104b, thereby allowing the input mechanism 104b to be positioned sub-flush relative to the cover 118a (e.g., Figure 1 shown).
