[0091] As shown in FIG1 , the first support member 31 can be substantially flat. The first support member 31 can be magnetic, for example, it can have a built-in magnet, so that the first support member 31 can be magnetically attracted to the magnet in the electronic device 5; and / or the edge of the first support member 31 can be provided with a retaining structure, such as a buckle or claw, so that the first support member 31 can be engaged with the electronic device 5.

[0092] As shown in FIG. 3 and FIG. 4 a , the second support member 33 may include a body 331 , and the body 331 may be substantially in the shape of a flat plate.

[0093] As shown in Figures 3 and 4a, a receiving groove 33a may be provided at the edge of the body 331. The receiving groove 33a is used to receive the connecting member 41 in the keyboard portion 4 when the second supporting member 33 is in contact with the connecting member 41 (described below).

[0094] As shown in Figure 4a, the second support member 33 may further include a covering member 332. The covering member 332 may be in the form of a generally flat, thin sheet, such as Mylar. The covering member 332 may be mounted within the receiving slot 33a, adjacent to the bottom wall of the receiving slot 33a, occupying only a portion of the space near the bottom wall. The inner wall of the receiving slot 33a may retain undesirable appearance effects such as texture and color variations from processing, which the covering member 332 can conceal, providing a decorative effect. In some embodiments, the covering member 332 may be made of a material such as stainless steel and may be magnetic to facilitate magnetic attraction between the second support member 33 and the connector 41 of the keyboard portion 4. In some embodiments, the magnetic force between the covering member 332 and the connector 41 is less than the magnetic force between the connector 41 and the electronic device 5 (described below). It will be appreciated that the magnetic design of the covering member 332 is not required. In other embodiments, the covering member 332 may be eliminated, or the covering member 332 and the receiving groove 33a may be eliminated. FIG4 b illustrates a second support member 33 in another embodiment, in which the covering member 332 and the receiving groove 33a are eliminated. The second support member 33 may be provided with a notch 33b extending through the second support member 33 along the thickness direction. The number of notches 33b may be at least one, for example, FIG4 b illustrates two notches.

[0095] As shown in Figures 1 and 2, the second support member 33 can rotate a certain angle relative to the first support member 31 and be supported on a table (e.g., a desktop), so that the bracket portion 3 is in a supported state. At this time, the back 5a of the electronic device 5 can be placed on the first support member 31, and the second support member 33 and the back 5a can form an angle a, so that the bracket portion 3 can position and support the electronic device 5. Because the second support member 33 can rotate continuously, the angle a can change continuously. The embodiment of the present application does not limit the value of the angle a.

[0096] As shown in FIG. 3 , the keyboard portion 4 may include a connecting member 41 and a keyboard body 42 . The connecting member 41 may be fixedly connected to an edge of the keyboard body 42 .

[0097] As shown in Figure 3, the keyboard body 42 may include a key core 421 and a touchpad 422, and the connector 41, the key core 421 and the touchpad 422 may be connected in sequence. The key core 421 may include a plurality of keys, and the touchpad 422 is used for touch input by the user. The keyboard body 42 may also include a built-in battery and a wireless communication module. The battery can store electrical energy and supply power to the wireless communication module. The wireless communication module is used to wirelessly communicate with the electronic device 5 to input the user's operations on the keyboard body 42 into the electronic device 5. The wireless communication module includes but is not limited to a Bluetooth module, a Wi-Fi module, an infrared (IR) module, etc.

[0098] As shown in Figures 1 and 3, the connector 41 is used to magnetically attract the back surface 5a of the electronic device 5 and establish a circuit connection between the keyboard body 42 and the electronic device 5 (described below). When the second support member 33 is rotated to align with the back surface 5a of the electronic device 5, the connector 41 can be accommodated in the receiving groove 33a of the second support member 33. This allows the bracket portion 3 to be flattened and reduces the thickness of the protective cover assembly 2 at the connector 41, which is beneficial for improving the user experience.

[0099] As shown in Figures 5 and 6, the connector 41 may include a base 411, a plurality of magnets 413, a first wireless coil 414, a cover plate 415, and a cover 412. Each of these will be described below.

[0100] As shown in FIG7 , the base 411 may be roughly a long plate-shaped structure. A partial surface of the base 411 may be recessed to form a first receiving groove 411a and a second receiving groove 411b. The first receiving groove 411a may be a rectangular stepped groove, and the second receiving groove 411b may be a relatively slender special-shaped groove. Several cavities 411c may also be formed inside the base 411, and each cavity 411c may accommodate at least one magnet 413. It is understandable that the above structure of the base 411 is merely a schematic and is not a limitation of the embodiments of the present application. For example, the first receiving groove 411a and / or the second receiving groove 411b may not be provided; the cavity 411c may not be formed inside the base 411, but the partial surface of the base 411 may be recessed to form a groove to accommodate the magnet 413, or a wall may be protruded from the surface of the base 411 to fix the magnet 413.

[0101] Figure 8 is a schematic diagram of the assembled structure of the first wireless coil 414, and Figure 9a is a schematic diagram of the exploded structure of the first wireless coil 414 of Figure 8. As shown in Figures 8 and 9a, the first wireless coil 414 may include a conductive wire 414a, a first adhesive layer 414b, a first flexible circuit board 414c, a nanocrystalline layer 414f, and a second adhesive layer 414g.

[0102] 9a , the first flexible circuit board 414c may include a first portion 414d and a second portion 414e connected to each other, and the first portion 414d and the second portion 414e may approximately form a T-shaped structure. The outer layer of the first flexible circuit board 414c may be a flexible material, such as polyurethane (PU) or non-woven fabric.

[0103] As shown in Figure 9a, the conductive wire coil 414a, first adhesive layer 414b, first portion 414d, nanocrystalline layer 414f, and second adhesive layer 414g can be stacked in sequence, with first adhesive layer 414b bonding conductive wire coil 414a to first portion 414d, and one side of second adhesive layer 414g bonding to nanocrystalline layer 414f. In conjunction with Figure 9a and Figure 6, the other side of second adhesive layer 414g can be bonded to the inner wall of first receiving groove 411a of base 411 (described below). The stacked structure including conductive wire coil 414a, first adhesive layer 414b, first portion 414d, nanocrystalline layer 414f, and second adhesive layer 414g can be referred to as a header 414h. Second portion 414e can be located outside header 414h and can be electrically connected to keyboard body 42.

[0104] Conductor coil 414a is a coil made of a conductive wire, the number of turns of which can be determined as needed. The conductive wire includes, but is not limited to, copper wire. Both ends of the conductive wire in conductor coil 414a can be electrically connected to first portion 414d. The bare wire diameter of conductor coil 414a can be approximately 0.16 mm, and the finished wire diameter can be approximately 0.18 mm.

[0105] Nanocrystalline layer 414f is a layer containing nanocrystalline material, which includes but is not limited to ferrite. Illustratively, nanocrystalline layer 414f may include several layers of nanocrystalline material and several layers of double-sided tape, wherein the nanocrystalline material and double-sided tape may be alternately stacked. The two opposing outer sides of nanocrystalline layer 414f may be single-sided tape, which may respectively bond nanocrystalline layer 414f to first portion 414d and to second adhesive layer 414g. Illustratively, nanocrystalline layer 414f may have a stacked structure of: single-sided tape - double-sided tape - nanocrystalline material - double-sided tape - nanocrystalline material ... double-sided tape - single-sided tape. Nanocrystalline layer 414f is configured to concentrate energy on one side of conductor coil 414a (e.g., the upper side in FIG. 9 a ) for transmission and reception, while blocking energy transmission and reception on the opposite side (e.g., the lower side in FIG. 9 a ).

[0106] In this embodiment, when the connector 41 is magnetically attracted to the back surface 5 a of the electronic device 5 , the first wireless coil 414 can be coupled to the wireless coil in the electronic device 5 , so that the electronic device 5 can wirelessly charge the battery built into the keyboard body 42 .

[0107] Table 2 below illustrates the specific composition of each layer in the first wireless coil 414 in Figure 9a, as well as the stacking thickness of the head portion 414h of the first wireless coil 414. The thickness control value can be 0.63 mm ± 0.05 mm; the welding height can be no more than 0.36 mm, and the Haba welding process can be used.

[0108] Table 1: Stacking thickness of the head portion 414h of the first wireless coil 414

[0109] In this embodiment, the thickest part of the first wireless coil 414 is at the head 414 h , but as shown in Table 1, its thickness is only about 0.6 mm. Therefore, the first wireless coil 414 is extremely thin, which helps to reduce the thickness of the connector 41 .

[0110] The above structure of the first wireless coil 414 is merely an example and is not intended to limit the embodiments of the present application.

[0111] Unlike the first wireless coil 414 shown in FIG9a , in another embodiment, as shown in FIG9b , the conductive coil 414a and the nanocrystalline layer 414f can be located on the same side of the first portion 414d of the first flexible circuit board 414c. The conductive coil 414a, nanocrystalline layer 414f, and first portion 414d can be stacked in sequence. It should be understood that FIG9b only illustrates key structures such as the conductive coil 414a, nanocrystalline layer 414f, and first flexible circuit board 414c. In practice, the first wireless coil 414 may also include other layers, such as an adhesive layer. For convenience, the following description will continue using the first wireless coil 414 shown in FIG9a as an example. It should be understood that the following description also applies to the embodiment shown in FIG9b .

[0112] In another embodiment, the first wireless coil may not be a wire coil wound by a wire, but may be an FPC (flexible printed circuit) wireless coil. The maximum thickness of such a first wireless coil is extremely small, for example, may be between 0.4 mm and 1.0 mm.

[0113] As shown in FIG6 , the cover plate 415 may be in the form of a sheet and may be made of insulating materials such as glass fiber.

[0114] As shown in FIG6 , the cover 412 may include a first cover 412a and a second cover 412b , both of which may be sheet-like structures and may be made of flexible materials, including but not limited to polyurethane, non-woven fabric, etc. The structures of the first cover 412a and the second cover 412b can be designed as needed and are not limited in this embodiment. In this embodiment, two cover members, the first cover 412a and the second cover 412b, are provided. In other embodiments, a single cover member may be used in place of the first cover 412a and the second cover 412b.

[0115] Next, the assembly structure of the various components in the connector 41 will be described.

[0116] Figure 10 shows the assembly structure of the first cover 412a and the base 411. Combining Figure 10 with Figure 6, the first cover 412a can be installed in the second receiving groove 411b of the base 411. Schematically, a portion of the first cover 412a can be located inside the second receiving groove 411b, and another portion can be located outside the second receiving groove 411b.

[0117] Figure 11 shows the assembly structure shown in Figure 10 , with the first wireless coil 414 mounted on the base 411. Combining Figure 11 with Figure 9a , the head portion 414h of the first wireless coil 414 can be inserted into the first receiving groove 411a of the base 411. The second adhesive layer 414g can be bonded to the bottom wall of the first receiving groove 411a, with the conductive coil 414a facing outward from the first receiving groove 411a. The second portion 414e of the first flexible printed circuit board 414c of the first wireless coil 414 can be positioned outside the first receiving groove 411a and above the first cover 412a, effectively sandwiching the first cover 412a between the base 411 and the second portion 414e.

[0118] Figure 12 shows the assembly structure shown in Figure 11, with the cover plate 415 mounted on the base 411. Combining Figures 12 and 11, the cover plate 415 fits into the first receiving groove 411a on the base 411, sealing the opening of the first receiving groove 411a. The cover plate 415 encloses the head portion 414h of the first wireless coil 414 within the first receiving groove 411a, securing and protecting the head portion 414h. It will be appreciated that in other embodiments, the cover plate 415 may be omitted.

[0119] As shown in conjunction with FIG12 and FIG5 , the second cover 412b can cover the cover plate 415, the base 411, the first cover 412a, and the second portion 414e. Covering refers to covering at least a portion. For example, the second cover 412b completely covers the cover plate 415 and the base 411, the second cover 412b can cover at least a portion of the first cover 412a, and the second cover 412b can cover a portion of the second portion 414e of the first flexible circuit board 414c. Another portion of the second portion 414e is located outside the second cover 412b and is electrically connected to the keyboard body 42.

[0120] As described above, when the second support member 33 is rotated to fit against the back surface 5a of the electronic device 5, the connector 41 can be accommodated in the receiving groove 33a of the second support member 33. As shown in FIG5 and FIG2 , the base 411 of the connector 41 can face the inside of the receiving groove 33a, and the second cover 412b of the connector 41 can face the outside of the receiving groove 33a. In this embodiment, the thickness of the second support member 33 and the connector 41 can be stacked to ensure that the thickness of the protective cover assembly 2 at the connector 41 is relatively small. Table 2 illustrates the stacking thickness from the bottom wall of the receiving groove 33a to the second cover 412b. Since the thickness of the connector 41 where the first receiving groove 411a is located is relatively large, it has a greater impact on the stacking thickness. Therefore, Table 2 lists the thickness of the components or parts corresponding to the first receiving groove 411a, from the bottom wall of the receiving groove 33a to the second cover 412b.

[0121] Table 2: Stacking thickness from the second support member 33 to the connecting member 41

[0122] As can be seen from Table 2, after the above-mentioned thickness stacking, when the second support member 33 is rotated to fit with the back surface 5a of the electronic device 5 and the connector 41 is accommodated in the accommodating groove 33a of the second support member 33, the total thickness from the second support member 33 to the connector 41 is only 2.2 mm, which makes the thickness of the circuit connection between the protective cover assembly 2 and the electronic device 5 extremely small, which can improve the user experience.

[0123] The following describes how the protective cover assembly 2 and the electronic device 5 of this embodiment are used in combination.

[0124] As shown in reference figure 1, the user can fit the first support member 31 with the back surface 5a of the electronic device 5 so that the first support member 31 and the electronic device 5 are magnetically attracted or engaged, and rotate the second support member 33 to a certain angle so that the second support member 33 is supported on the table. The user can fit the back surface 5a of the electronic device 5 with the connector 41 so that the back surface 5a and the connector 41 are magnetically attracted. In other embodiments, the connector 41 may be provided with a structural feature, or both the connector 41 and the electronic device 5 may be provided with a structural feature, and the structural feature includes but is not limited to a claw, or a combination of a buckle and a slot, through which the connector 41 and the back surface 5a can be detachably connected. In this embodiment, the detachable connection between the connector 41 and the back surface 5a can be achieved by at least one of a magnet and a structural feature.

[0125] In this embodiment, when the back surface 5a of the electronic device 5 is detachably connected to the connector 41, the electronic device 5 can be coupled to the connector 41. This allows the electronic device 5 to be supported and positioned by the bracket portion 3. When the battery in the keyboard body 42 needs to be charged, the electronic device 5 can wirelessly charge the battery via the first wireless coil 414 in the connector 41. The keyboard body 42 and the electronic device 5 can communicate wirelessly. This wireless communication can occur after the electronic device 5 is positioned within the protective cover assembly 2, or while the electronic device 5 is separated from the protective cover assembly 2, although this embodiment is not limiting.

[0126] With reference to Figures 1 and 2 , when the electronic device 5 is positioned on the protective cover assembly 2, if the user wishes to fold the protective cover assembly 2 closed, the user can flip the electronic device 5 toward the keyboard body 42, which will cause the connector 41 to bend. The user can flip the second support member 33 toward the electronic device 5 so that it rests against the back surface 5a of the electronic device 5. The connector 41 will then be accommodated within the receiving groove 33a of the second support member 33. This allows the bracket portion 3 to be flattened and reduces the thickness of the protective cover assembly 2 at the connector 41, thereby improving the user experience. As an example, a magnet in the connector 41 can be magnetically attracted to the cover 332 in the second support member 33. In other embodiments, the connector 41 and / or the second support member 33 can be provided with structural features (including but not limited to a combination of a snap and a slot, Velcro, etc.) that enable a detachable connection between the connector 41 and the second support member 33. In this embodiment, the detachable connection between the connector 41 and the second support member 33 can be achieved through at least one of a magnet and a structural feature.

[0127] When the protective cover assembly 2 is folded and closed, the user can unfold the protective cover assembly 2 again and rotate the second support member 33 to form an angle a with the electronic device 5, so that the bracket portion 3 enters the supporting state. In order to prevent the second support member 33 from pulling the connecting member 41 away from the electronic device 5 when rotating, the magnetic force between the second support member 33 and the connecting member 41 can be smaller than the magnetic force between the connecting member 41 and the electronic device 5.

[0128] In addition to the usage described above, as shown in Figure 1, the user can also fold the first support member 31 to support it on the table, so that the second support member 33 fits the back side 5a of the electronic device 5, and the connecting member 41 is accommodated in the receiving groove 33a of the second support member 33. In this way, the protective cover assembly 2 can also support the electronic device 5.

[0129] The solution of embodiment 1 can be applied to a keyboard solution including a touchpad. In this embodiment, when the electronic device 5 is placed on the protective cover assembly 2, the connector 41 connected to the circuit of the electronic device 5 is located on the back 5a of the electronic device 5. This back-connection design does not require the electronic device 5 to increase its thickness, which is conducive to achieving a thinner and lighter electronic device 5. By designing the specific structure of the connector 41, a keyboard solution with good adaptability to the electronic device 5, mature structure, and good mass production is provided, which can enhance product competitiveness. By using an ultra-thin wireless coil, providing a receiving groove 33a on the second support member 33, and stacking the thickness of the second support member 33 and the connector 41, when the electronic device 5 is positioned on the protective cover assembly 2 and the protective cover assembly 2 is closed, the thickness of the circuit connection between the protective cover assembly 2 and the electronic device 5 can be greatly reduced (for example, it can be thinner by at least about 1mm compared to conventional solutions), thereby enhancing the user experience. When the electronic device 5 is placed on the protective cover assembly 2 and the bracket portion 3 is in the supporting position, the connector 41 is hidden between the electronic device 5 and the second support member 33. The connector 41 is completely obscured by the electronic device 5 and the second support member 33, making it invisible to the user from both the front of the electronic device 5 and the side where the second support member 33 is located, thus improving the aesthetics and user experience. Furthermore, the bracket portion 3 and keyboard portion 4 are detachable, allowing users to use only the bracket portion 3 or the keyboard portion 4. The protective cover assembly 2 has fewer components, a simple structure, is relatively lightweight, and is relatively low in cost.

[0130] The connector 41 of the first embodiment uses a first wireless coil 414, which is coupled to the electronic device 5 via the first wireless coil 414. However, the connector of the second embodiment uses a connector in place of the first wireless coil 414. The connector can electrically contact the electronic device 5 to achieve electrical connection. This will be described in detail below.

[0131] As shown in FIG13 and FIG14 , in an implementation of the second embodiment, the connecting member may include a connector 6. The connector 6 may include a printed circuit board 62, a second flexible circuit board 63 and a spring 61.

[0132] As shown in FIG. 14 , the printed circuit board 62 can be called a “broken-board circuit board”. The printed circuit board 62 can be hollowed out to form a mounting through hole 62 b , and a plurality of connecting through holes 62 a can be opened around the mounting through hole 62 b .

[0133] As shown in Figures 13 and 14, schematically, two spring clips 61 can be provided, and the two spring clips 61 can be located in the mounting through hole 62b. The two spring clips 61 can be arranged in a mirror image, for example. In other embodiments, the number of the spring clips can be at least two, for example, three.

[0134] Figures 15-17 are schematic diagrams of the structure of the spring clip 61 from different perspectives. As shown in Figures 15-17, the spring clip 61 can include a base plate 611. The base plate 611 can be generally flat, with a plurality of weld legs 612 connected to its edges by bending. As shown in Figures 15 and 14, a weld leg 612 can be welded to a connecting through hole 62a. Both sides of the base plate 611 can be provided with protruding limiting side walls 613. The limiting side walls 613 can have a curved shape. The limiting side walls 613 on both sides and the base plate 611 can generally form a C-shaped structure.

[0135] As shown in Figures 15-17, the spring clip 61 may further include an elastic arm 614, which is connected to the base plate 611 and forms a bent structure. The elastic arm 614 may include an elastic portion 614a, a contact portion 614b, and an elastic portion 614c, which are sequentially connected. The elastic portion 614a may be bent and connected to the base plate 611. The elastic portion 614a and the elastic portion 614c may be roughly symmetrically distributed on opposite sides of the contact portion 614b. The elastic portion 614a and the elastic portion 614c may both be inclined relative to the base plate 611, and the contact portion 614b may be approximately parallel to the base plate 611. A gap is provided between the elastic portion 614a, the contact portion 614b, and the elastic portion 614c and the base plate 611, which facilitates downward elastic deformation of the elastic arm 614. The spring clip 61 of this embodiment has two elastic regions, the elastic portion 614a and the elastic portion 614c, which can provide a relatively large elastic force.

[0136] As shown in Figures 15-17, the spring 61 may further include a contact 615, which may be connected to the side of the contact portion 614b facing away from the base plate 611. The contact 615 may be plated with a metal layer for corrosion and oxidation resistance, such as gold, platinum, nickel, or silver.

[0137] As shown in Figures 15 and 17, the spring piece 61 may further include a limiting portion 616, which may be connected to the side of the elastic portion 614c facing away from the elastic portion 614a. The limiting portion 616 may be located between the two limiting side walls 613, and the opposite sides of the limiting portion 616 may be bent and respectively maintain a certain gap or contact with the inner surfaces of the two limiting side walls 613. The flat portion of the limiting portion 616 may maintain a certain gap or contact with the bottom plate 611. Thus, the limiting portion 616 is limited by the two limiting side walls 613 and the bottom plate 611, and the limiting portion 616 can basically only move along the length direction of the limiting side walls 613 and basically cannot move in other directions.

[0138] In this embodiment, the spring clip 61 can be considered to be a pogo pin. As shown in Figure 16, the distance from the surface where the contact portion 614b is connected to the contact 615 to the surface of the base plate 611 facing away from the contact portion 614b can be defined as h. When the spring clip 61 is in an unpressurized free state, h is the free height of the spring clip 61, which can be, for example, 0.6mm-1.5mm. When the contact 615 is pressurized, it will move downward, and the downward stroke of the contact 615 (or the stroke of the spring clip 61) can be, for example, 0mm-0.5mm. After completing this stroke, h is the working height of the spring clip 61, which can be, for example, 0.1mm-1.5mm. Schematically, the working height can be 0.8mm. Compared to the traditional pogo pin with a working height of 1.6mm, the spring clip 61 of this embodiment has a smaller working height, which is conducive to making the spring clip 61 and the entire connector thinner.

[0139] The material of the spring piece 61 in this embodiment can be a copper substrate. The spring piece 61 can flow a large current of more than 4A and has a lifespan of more than 20,000 times.

[0140] The outer layer of the second flexible circuit board 63 can be made of a flexible material, such as polyurethane or non-woven fabric. As shown in Figures 13 and 14 , the second flexible circuit board 63 can include a third portion 63a and a fourth portion 63b. The third portion 63a is electrically connected to the printed circuit board 62. The third portion 63a, the printed circuit board 62, and the spring 61 mounted on the printed circuit board 62 form the head portion 6h of the connector 6. The fourth portion 63b can be located outside the head portion 6h. The fourth portion 63b can be electrically connected to the keyboard body.

[0141] As shown in FIG18 , in another embodiment of the second embodiment, the spring piece 71 of the connector may include a base plate 711, a solder pin 712, an elastic arm 714, and a contact 715. Unlike the previous embodiment, the elastic arm 714 of the spring piece 71 has an elastic region that can provide a relatively small elastic force, such as 100g.

[0142] 19 shows a schematic diagram of the assembly structure of the spring 71 and the printed circuit board 72, wherein the solder pins 712 of the spring 71 can be soldered to the connecting through holes of the printed circuit board 72. Schematically, the connector can have three springs 71 and therefore three contacts 715.

[0143] In the second embodiment, the connector may include at least two springs and have at least two contacts.

[0144] The following uses the connector 6 in the second embodiment as an example to illustrate the assembly structure of the connector in the second embodiment and other components in the connector.

Illustratively, when the connection structure 223 is a wireless coil, the connection structure 223 can be embedded within the second sub-assembly 222. When the connection structure 223 is a connector, the majority of the connection structure 223 can be concealed within the second sub-assembly 222, with the contacts of the connection structure 223 exposed on the surface of the second sub-assembly 222.

[0155] The following describes how the protective cover assembly 20 of this embodiment is used in conjunction with an electronic device.

[0156] Referring to Figures 20 to 22, the user can rotate the second support member 33 to a certain angle so that the second support member 33 is supported on the table. At this time, an angle b is formed between the second support member 33 and the second sub-member 222. Exemplarily, the user can magnetically attract the second sub-member 222 to the connector 41. In other embodiments, structural features (including but not limited to a combination of buckles and slots, Velcro, etc.) can be provided on the connector 41 and / or the second sub-member 222, and the connector 41 and the second sub-member 222 are detachably connected through the structural features. In this embodiment, the detachable connection between the connector 41 and the second sub-member 222 can be achieved by at least one of a magnet and a structural feature.

[0157] When the second sub-assembly 222 is detachably connected to the connector 41, the connector 41 is positioned between the second sub-assembly 222 and the second support member 33, and the connector 41 is electrically connected or coupled to the connection structure 225. The user can then place the back of the electronic device on the second sub-assembly 222, which will magnetically attract and / or snap onto the electronic device. This allows the electronic device to be supported and positioned on the protective cover assembly 20 and establish an electrical connection with the keyboard body 42.

[0158] If the keyboard body 42 has a built-in battery and a wireless communication module, the battery can supply power to the wireless communication module. At this time, the electronic device and the connecting structure 223 are coupled or electrically contacted, and the connecting structure 225 and the connector 41 can be electrically contacted or coupled. When the battery needs to be charged, the electric energy output by the electronic device can be stored in the battery through the connecting structure 223, the transmission member 224, the connecting structure 225 and the connector 41. Through the wireless communication module, the keyboard body 42 and the electronic device 5 can communicate wirelessly. The wireless communication can be carried out after the electronic device is positioned in the protective cover assembly 20, or it can be carried out when the electronic device 5 is separated from the protective cover assembly 20, which is not limited in this embodiment.

[0159] If keyboard body 42 does not have a battery and a wireless communication module, the electronic device is in electrical contact with the connecting structure 223, and the connecting structure 225 is in electrical contact with the connector 41. Through the connecting structure 223, the transmission element 224, the connecting structure 225, and the connector 41, the electronic device can supply power to the keyboard body 42, and the keyboard body 42 can communicate with the electronic device.

In addition, the first support member 22 includes the second sub-component 222, which can meet the product requirements of not requiring high thickness of the electronic device and the thickness of the bracket portion, and the first support member 22 has better strength and rigidity, and the support of the electronic device is more stable and reliable.

[0161] Unlike the third embodiment, in another embodiment, referring to FIG20 , the second sub-component 222 may not be provided with the connection structure 223, the transmission component 224, and the connection structure 225. The second sub-component 222 serves only as a structural component to support the electronic device and does not have a circuit connection function. In this embodiment, the connector 41 may include a first wireless coil 414, and the first wireless coil 414 may be coupled to the wireless coil in the electronic device through the second sub-component 222. Alternatively, the connector 41 may include a connector, as shown in FIG23 , and a through hole 222a may be provided at a corresponding position of the second sub-component 222. The contacts in the connector may pass through the through hole 222a and electrically contact the contact piece on the back of the electronic device.

In addition, the second support member 33 and the connector 41 are detachably connected, for example, by magnetic attraction, by Velcro adhesion, and / or by structural feature engagement. The connector 41 can be located within the angle a formed by the electronic device 5 and the second support member 33. In combination with Figure 24 and Figure 6, when the connector 41 includes a connector, the contact of the connector can face the first receiving groove 411a, pass through the through hole of the bottom wall of the first receiving groove 411a, and face the second support member 33. Circuit structures are arranged in the first support member 31 and the second support member 33 . The electronic device 5 can establish a circuit connection with the connector 41 through the circuit structures in the first support member 31 and the second support member 33 , which will be explained below.

[0163] FIG25 illustrates the structure of the first support member 31 and the second support member 33 when they are flattened. As shown in FIG25 , the protective cover assembly 30 may further include a connecting structure 34 (referred to as the first connecting structure 34), a transmission member 35 (referred to as the first transmission member 35), and a connecting structure 36 (referred to as the second connecting structure 36). The transmission member 35 is connected between the connecting structure 34 and the connecting structure 36. The connecting structure 34 may be provided on the first support member 31, and the connecting structure 36 may be provided on the second support member 33. A portion of the transmission member 35 is provided on the first support member 31, and another portion is provided on the second support member 33.

[0164] Illustratively, the connection structure 34 can be a wireless coil (in this case, the connection structure 34 can be referred to as a third wireless coil), which is used to couple with an electronic device to enable wireless charging of the battery within the keyboard body 42 by the electronic device (described below). This wireless coil can be the first wireless coil 414 described above, or any other suitable wireless coil, and this embodiment is not limited thereto. In another embodiment, the connection structure 34 can also be a connector, which is used to electrically contact the electronic device to enable the electronic device to charge the battery within the keyboard body 42; or to enable the electronic device 5 to supply power to the keyboard body 42, enabling wired communication between the keyboard body 42 and the electronic device 5 (described below). This connector can be the connector described in the above embodiment (such as connector 6), or any other suitable connector, and this embodiment is not limited thereto. Illustratively, when the connection structure 34 is a wireless coil, the connection structure 34 can be embedded within the first support member 31. When the connection structure 34 is a connector, the majority of the connection structure 34 can be concealed within the first support member 31, with the contacts of the connection structure 34 exposed on the surface of the first support member 31.

[0165] Schematically, the transmission member 35 can be an FPC or a cable, and the transmission member 35 connects the connection structure 34 and the connection structure 36. Schematically, the portion of the transmission member 35 located on the first support member 31 can be buried in the first support member 31, and the portion of the transmission member 35 located on the second support member 33 can be buried in the second support member 33.

[0166] Schematically, the connection structure 36 can be a conductive contact, such as a contact made of copper or other materials. The conductive contact is used to electrically contact the connector in the connector 41. In another embodiment, the connection structure 36 can be any component that can achieve circuit connection, including but not limited to a connector (electrically contacting the connector in the connector 41) or a wireless coil (the connection structure 36 is coupled with the first wireless coil 414 in the connector 41). Schematically, when the connection structure 36 is a conductive contact, the connection structure 36 can be exposed on the surface of the second support member 33; when the connection structure 36 is a connector, most of the connection structure 36 can be hidden in the second support member 33, and the contact of the connection structure 36 can be exposed on the surface of the second support member 33; when the connection structure 36 is a wireless coil, the connection structure 36 can be buried in the second support member 33.

[0167] Figure 26 shows the decomposed structure of the second support member 33. As shown in Figure 26, the second support member 33 may include a body 331, a magnet 333 and a cover member 332. A receiving groove 33a may be provided at the edge of the body 331, and the magnet 333 may be installed in the receiving groove 33a. At least a portion of the connecting structure 36 may be located in the receiving groove 33a. The cover member 332 is installed in the receiving groove 33a and encapsulates the magnet 333 and the connecting structure 36 in the receiving groove 33a. The cover member 332 may be close to the bottom wall of the receiving groove 33a, and the cover member 332 only occupies part of the space of the receiving groove 33a close to the bottom wall. A through hole 332a may be provided on the cover member 332 for the connecting structure 36 to be exposed or pass through.

[0168] The following describes how the protective cover assembly 30 of this embodiment is used in conjunction with the electronic device 5 .

[0169] As shown in Figures 24 and 25, when the electronic device 5 is positioned on the protective cover assembly 30, the first support member 31 can be magnetically attracted and / or snapped to the electronic device 5. The wireless coil in the electronic device 5 can be coupled and connected to the connecting structure 34 (which is a wireless coil), or the contact piece on the back of the electronic device 5 can be electrically contacted with the connecting structure 34 (which is a connector). The magnet 333 in the second support member 33 can be magnetically attracted to the magnet in the connecting member 41, or the second support member 33 and the connecting member 41 can also form a detachable connection through structural features. The connecting structure 36 (which is a conductive contact or connector) can be electrically contacted with the contact of the connector in the connecting member 41, or the connecting structure 36 (which is a wireless coil) can be coupled and connected to the first wireless coil 414 in the connecting member 41. Thus, through the connecting structure 34, the transmission member 35, the connecting structure 36 and the connecting member 41, the electronic device 5 can establish a circuit connection with the keyboard body 42. In this embodiment, the electronic device 5 can wirelessly charge the keyboard body 42, and the keyboard body 42 can wirelessly communicate with the electronic device 5; or, the electronic device 5 can supply power to the keyboard body 42, and the keyboard body 42 can communicate with the electronic device 5 by wire. The specific implementation is the same as described above and will not be repeated here.

[0170] The solution of Example 4 can be applied to keyboard solutions without a touchpad. The solution of Example 4 also has the technical effects of the above-mentioned embodiments, for example: it adopts a back-connection design, which is conducive to achieving the lightweight and thinness of the electronic device 5; it provides a keyboard solution with good adaptability to the electronic device 5, mature structure, and good mass production, which can enhance product competitiveness; it can greatly reduce the thickness of the circuit connection between the protective cover assembly 30 and the electronic device 5, improving the user experience; the connector 41 is completely shielded by the second support member 33 and the electronic device 5, improving the aesthetics and user experience; the bracket portion 3 and the keyboard portion 4 are detachable, which can meet the needs of users who only use the bracket portion 3 or the keyboard portion 4. In addition, the protective cover assembly 30 has fewer components, a simple structure, is relatively light, and has a low cost.

[0171] Figures 27 and 28 show the protective cover assembly 40 of the fifth embodiment. Unlike the above-mentioned fourth embodiment, the first support member 31 of the protective cover assembly 40 may include a first sub-member 311 and a second sub-member 312, which may be arranged in a stacked manner. The area of ​​the first sub-member 311 may be smaller than the area of ​​the second sub-member 312. The first sub-member 311 may cover the upper area of ​​the second sub-member 312, and the lower area of ​​the second sub-member 312 may exceed the boundary of the first sub-member 311. The first sub-member 311 and the second sub-member 312 may be fixedly connected, for example, by bonding. The second support member 33 is hinged to the first sub-member 311, and the second support member 33 and the first sub-member 311 are located on the same side of the second sub-member 312. When the second support member 33 is rotated to be parallel to the first sub-member 311, the second support member 33 may basically cover the lower area of ​​the second sub-member 312.

[0172] Referring to Figures 27 and 28, the second sub-component 312 can serve only as a structural component supporting the electronic device, without any circuit structure. The connecting structure 34 can be provided on the first sub-component 311, and a portion of the second transmission component can be provided on the first sub-component 311. Schematically, the connecting structure 34 can be a connector, and a through hole 312a can be provided on the second sub-component 312 to expose the contacts of the connecting structure 34. In another embodiment, the connecting structure 34 can be a wireless coil, and the second sub-component 312 can be free of the through hole 312a. The second sub-component 312 can be magnetic, for example, it can have a built-in magnet; and / or, the edge of the second sub-component 312 can be provided with a holding structure, such as a buckle or a claw.

[0173] The following describes how the protective cover assembly 40 of this embodiment is used in conjunction with an electronic device.

[0174] As shown in Figure 27 , when the electronic device is positioned on the protective cover assembly 40, the first sub-component 311 of the first support member 31 can be magnetically attracted or snapped to the electronic device. The contacts on the back of the electronic device 5 can be electrically connected to the connecting structure 34 (a connector), or the wireless coil in the electronic device can be coupled to the connecting structure 34 (a wireless coil). The second support member 33 can be removably connected to the connector 41 through magnetic attraction and / or structural features. The connecting structure 36 (a conductive contact or connector) can be electrically connected to the connector in the connector 41, or the connecting structure 36 (a wireless coil) can be coupled to the first wireless coil in the connector 41. Thus, through the connecting structure 34, the second transmission member, the connecting structure 36, and the connector 41, the electronic device can establish an electrical connection with the keyboard body 42. In this embodiment, the electronic device can wirelessly charge the keyboard body 42, and the keyboard body 42 can communicate wirelessly with the electronic device; alternatively, the electronic device can supply power to the keyboard body 42, and the keyboard body 42 can communicate wiredly with the electronic device. The specific implementation is the same as described above and will not be repeated here.

[0175] The solution of the fifth embodiment can be applied to keyboard solutions without a touchpad. The solution of the fifth embodiment also has the technical effects of the above embodiments, for example: it adopts a back-connection design, which is conducive to achieving the lightness and thinness of electronic devices; it provides a keyboard solution with good adaptability to electronic devices, mature structure, and good mass production, which can enhance product competitiveness; it can greatly reduce the thickness of the circuit connection between the protective cover assembly 40 and the electronic device, improving user experience; the connector 41 is completely blocked by the second support member 33 and the electronic device, improving the aesthetics and user experience; the bracket part 3 and the keyboard part 4 are detachable, which can meet the needs of users to use only the bracket part 3 or the keyboard part 4. In addition, the first support member 31 includes the second sub-component 312, which can meet the product requirements for the thickness of the electronic device and the thickness of the bracket part that are not high, and the strength and rigidity of the first support member 31 are better, and the support of the electronic device is more stable and reliable.

[0176] Different from the fifth embodiment, in the sixth embodiment, a part of the transmission component 35 and the connection structure 34 can be arranged on the second sub-component 312, and there is no circuit structure on the first sub-component 311, so that a circuit connection between the electronic device and the keyboard body 42 can be established.

[0177] Schematically, in any embodiment of the present application, one end of the connector 41 can form a flexible connection with the keyboard body 42, and the other end of the connector 41 is a free end relative to the keyboard body 42. When the keyboard portion 4 is separated from the bracket portion 3, the flexible connection enables the connector 41 to bend and flip relative to the keyboard body 42. For example, the flexible connection can be achieved by the material and structure of the connector 41 itself. Schematically, when the connector 41 is bent to the back of the keyboard body 42, the connector 41 can be detachably connected to the back of the keyboard body 42, wherein the back is opposite to the side of the keyboard body 42 where the keys are provided, and the detachable connection includes but is not limited to magnetic attraction, adhesion by Velcro, snap-fit, etc. Alternatively, when the connector 41 is bent to the back of the keyboard body 42, the connector 41 is not connected to the back of the keyboard body 42, but is only in loose contact.

[0178] Taking the protective cover assembly 40 of Example 5 (the keyboard body 42 lacks a touchpad and has a keyboard connection area 423) as an example, as shown in Figures 29 and 30, the keyboard connection area 423 has a back surface 423a, which is opposite the side of the keyboard body 42 provided with the keys 421a. The connector 41 can form a flexible connection with the keyboard connection area 423 and can be bent to the back surface 423a, where it can be detachably connected.

[0179] It can be understood that when the keyboard body 42 has a key core 421 and a touchpad, but no keyboard connection area 423, for example, as shown in reference Figure 3, the connecting member 41 can also form a flexible connection with the key core 421, and the connecting member 41 can be bent to the back of the key core 421 and detachably connected to the back of the key core 421.

[0180] In this embodiment, when the keyboard portion 4 is separated from the bracket portion 3, the connector 41 flips over to the back of the keyboard body 42 and removably connects to it. This allows the connector 41 to be fixed to the back of the keyboard body 42, giving the keyboard portion 4 a relatively simple and neat appearance. When the user types on the keyboard body 42, the connector 41 also raises the inclination angle of the keyboard body 42, facilitating user input and improving the user experience. It is understood that if the connector 41 flips over to the back of the keyboard body 42 but is not connected to it, but only in contact with it, a similar effect can be achieved.

[0181] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
