Description

Technical Field

[0001] The present application relates to the field of electronic equipment, and in particular to an electronic equipment component. Background Art

[0002] With the development of science and technology, wireless charging technology has gradually been applied to electronic devices such as mobile phones and tablets. Wireless charging technology mainly uses the principle of electromagnetic induction to achieve energy transfer through energy coupling through coils.

[0003] At present, electronic devices can be placed on a charging base for wireless charging. The charging base is used to convert electric current into a magnetic field. When the current of the charging base changes, a constantly changing magnetic field is generated. When the electronic device is placed on the charging base, when the magnetic field of the charging base is constantly changing, the magnetic flux in the receiving coil in the electronic device is also constantly changing, and an induced current is generated. The induced current can be processed and converted into direct current by the charging circuit in the electronic device, so that the battery of the electronic device can be charged, thereby realizing the wireless charging function of the electronic device. However, the charging efficiency of existing electronic devices when charging at high power (for example, power greater than or equal to 35w) cannot be achieved at the same time as their own thinness, which makes the charging efficiency of electronic devices low when charging at high power.

[0004] Therefore, how to improve the charging efficiency of electronic devices during high-power charging while taking into account the thinness and lightness of the electronic devices has become a technical problem to be solved. Summary of the invention

[0005] The present application provides an electronic device component, which can improve the charging efficiency of the electronic device during high-power charging, while also taking into account the lightness and thinness of the electronic device, and can enable users to obtain the experience of magnetic wireless charging.

[0006] An embodiment of the present application provides an electronic device assembly, which includes an electronic device and a protective shell, wherein the electronic device and the protective shell are detachably mounted, wherein:

[0007] The electronic device comprises a housing and a circuit board located in the housing, wherein the circuit board has a charging circuit, and the charging circuit has charging contacts;

[0008] The protective case includes:

[0009] A protective shell body and contact points, wherein the protective shell body is configured to be disposed on an outer surface of the housing when the electronic device and the protective shell are mounted together;

[0010] A first receiving coil, the first receiving coil is located in the protective shell body;

[0011] The contact contacts are arranged on a side of the protective shell body facing the housing in correspondence with the charging contacts, and are connected to each other; when the electronic device and the protective shell are installed together, the contact contacts are in contact with the charging contacts;

[0012] The magnetic part is assembled with the protective shell body.

[0013] The embodiment of the present application is achieved by setting a protective shell in an electronic device assembly, by setting a first receiving coil of the protective shell and a contact point, because the charging circuit of the electronic device has a charging contact, and when the electronic device and the protective shell are installed together, the contact point and the charging contact are in contact, therefore, when the electronic device and the protective shell are installed together, the first receiving coil can be connected to the charging circuit through the contact point and the charging contact, and form a complete wireless charging system with the charging circuit to realize the wireless charging function of the electronic device. Since the first receiving coil is located in the protective shell body of the protective shell, the thickness of the first receiving coil is not limited by the electronic device, so that the first receiving coil can have a larger thickness and a smaller impedance, thereby improving the charging efficiency of the electronic device during high-power charging, and realizing fast charging of the electronic device during high-power charging.

[0014] Furthermore, since the first receiving coil is located inside the protective shell body, while ensuring the wireless charging of the electronic device, the existence of the first receiving coil can also avoid affecting the thickness of the electronic device, so as to achieve the thinness of the electronic device. In addition, by setting the charging circuit inside the electronic device, it is possible to avoid the charging circuit affecting the thickness of the protective shell, which is conducive to the thinness of the protective shell. Finally, by setting the magnetic part, the user can get the experience of magnetic wireless charging when placing the electronic device with the protective shell installed on the charging base.

[0015] In some optional embodiments, the housing includes a middle frame and a back cover disposed on the middle frame;

[0083] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0084] The embodiment of the present application provides an electronic device, wherein the electronic device may include but is not limited to a mobile phone, a tablet computer (i.e., a pad), a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a telephone watch, a walkie-talkie, a handheld terminal, and other electronic devices with a wireless charging function.

[0085] The wireless charging function of electronic devices is realized based on wireless charging technology. The principle of wireless charging technology is the same as that of transformers. Both use the principle of electromagnetic induction to transfer energy between electronic devices and charging bases, thus realizing the wireless charging function of electronic devices.

[0086] Taking a mobile phone as an example, the principles of the wireless functions of electronic devices are further explained below.

[0087] A magnetic core and a transmitting coil are provided in the charging base of the mobile phone. The charging base can be called a wireless charging base. The transmitting coil is wound around the outside of the magnetic core and can convert the current into a magnetic field. When the current of the charging base changes, the transmitting coil can convert the changing current into a constantly changing magnetic field. When the mobile phone is placed on the charging base and the magnetic field generated by the transmitting coil is constantly changing, since the magnetic field can propagate in space, the magnetic flux in the receiving coil in the electronic device is also constantly changing, and it induces the transmitting coil to generate an induced current. The charging circuit in the mobile phone can rectify the induced current and convert it into direct current, which can charge the battery of the mobile phone through direct current, thereby realizing the wireless charging function of the mobile phone.

[0088] The structure of the electronic device of the present application is further described below by taking a mobile phone as an example.

[0089] Figure 1 An overall view of an electronic device 100 is shown. Figure 2 Shows Figure 1 1 is an exploded schematic diagram of an electronic device 100, which only shows a partial structure of the electronic device 100 and does not constitute a limitation on the structure of the electronic device 100.

[0090] Combine the following Figure 1 and Figure 2 The structure of the electronic device 100 is described in detail. The electronic device 100 includes a middle frame 11, which is the main supporting structure of the electronic device 100. Figure 2 As shown, the electronic device 100 further includes a back cover 12 , which covers and is connected to one side of the middle frame 11 , and together with the middle frame 11 forms a housing 1 of the electronic device 100 .

[0091] Continue to see Figure 2The middle frame 11 includes a middle plate 111 and a frame 112 which are connected to each other. The frame 112 may be a square ring structure formed by connecting a plurality of side frames end to end. The frame 112 is arranged around the peripheral edge of the middle plate 111 and is connected to the peripheral edge of the middle plate 111. The back cover 12 is arranged on one side of the middle frame 11 and is connected to the frame 112, so as to realize the setting and fixing of the back cover 12 on the middle frame 11. The display screen 5 of the electronic device 100 is arranged on the side of the middle frame 11 opposite to the back cover 12 and is connected to the frame 112, so as to realize the setting and fixing of the display screen 5 on the middle frame 11. The display screen 5 may provide a display interface for the electronic device 100 and an interactive interface with the user.

[0092] Continue to see Figure 2 The back cover 12 can form a containing cavity with the middle frame 11, which is used to accommodate the circuit board, battery 4 (not shown), camera module and other devices of the electronic device 100. The circuit board includes a main circuit board 2. The main circuit board 2 usually carries modules such as a processor module, a system on chip (SoC), a storage module, a communication module, a radio frequency module, and a power management module. The main circuit board 2 is located in the containing cavity surrounded by the back cover 12 and the middle frame 11, and is located on one side of the first end of the middle frame 11. The display screen 5 can be electrically connected to the main circuit board 2, and can be used to display various information, and can also receive information input by the user.

[0093] Continue to see Figure 2 The circuit board also includes a sub-circuit board 3, which usually carries modules such as an electrical connector and a speaker. The sub-circuit board 3 is located in the accommodation cavity surrounded by the back cover 12 and the middle frame 11, and is located on one side of the second end of the middle frame 11.

[0094] When the battery 4 is in the accommodation cavity surrounded by the back cover 12 and the middle frame 11, it can be located between the main circuit board 2 and the auxiliary circuit board 3. The position of the camera module and other devices in the accommodation cavity can refer to the settings in existing electronic devices 100 such as mobile phones, and no further limitation is made here.

[0095] In some embodiments, the display screen 5 can also form another accommodating cavity with the middle frame 11 to accommodate devices such as a camera module. Similarly, the position of the camera module in the accommodating cavity surrounded by the display screen 5 can refer to the arrangement in existing electronic devices 100 such as mobile phones, and no further limitation is made here.

[0096] Figure 2 The structure of the electronic device 100 including a middle frame 11 is shown. Figure 2 The electronic device 100 in the embodiment may be referred to as a non-foldable electronic device.

[0097] In some embodiments, the electronic device 100 may also be a foldable electronic device, and the foldable electronic device includes two middle frames 11. The two middle frames 11 may be rotatably connected by a hinge mechanism, so that the two middle frames 11 can be relatively rotated around the hinge mechanism to achieve the flattening and folding of the foldable electronic device. When the foldable electronic device is in a folded state, the two middle frames 11 can be relatively rotated around the hinge mechanism to overlap each other. When the foldable electronic device is in a flattened state, the two middle frames 11 can be relatively rotated around the hinge mechanism to be in the same plane. The back cover 12 can be covered on one of the middle frames 11. Alternatively, in some embodiments, the electronic device 100 may also include two back covers 12, and the two back covers 12 are respectively covered with a middle frame 11. The above two situations are not particularly limited in this application.

[0098] The structure of the foldable electronic device is further described below by taking an example where the rear cover 12 covers a middle frame 11 .

[0099] The display screen 5 of the foldable electronic device may include a flexible display screen, which may be simultaneously covered on the same side of the two middle frames 11, so that the flexible display screen can be folded as the electronic device 100 is folded, and can be folded as the electronic device 100 is flattened, so that while the foldable electronic device is converted between the folded state and the flattened state, the large display area of ​​the electronic device 100 and the convenience of carrying by the user can be satisfied. Alternatively, in some embodiments, in addition to the flexible display screen, the display screen 5 may also include a rigid display screen, which may be covered on the side of the middle frame 11 that is not provided with the back cover 12 and is opposite to the flexible display screen.

[0100] The structure of the electronic device 100 is further described below by taking a non-foldable electronic device as an example.

[0101] In order to realize the wireless charging function of the electronic device 100, the existing electronic device is built with the receiving coil and the charging circuit described above. For example, the receiving coil can be located on the back cover of the existing electronic device or in the accommodation cavity surrounded by the back cover and the middle frame, and the charging circuit can be located on the main circuit board of the existing electronic device. Due to the presence of the receiving coil and the charging circuit, the thickness and weight of the existing electronic device will increase. In addition, under the research and development trend of lightweight electronic devices, the thickness of the entire electronic device is relatively thin, which limits the thickness of the receiving coil, resulting in the thickness of the receiving coil cannot be made larger. Due to the limited thickness of the receiving coil, when the electronic device is placed on the charging base described above and charged at high power, heat will accumulate in the electronic device, and the charging efficiency of the electronic device during high-power charging will be reduced, affecting the charging speed of the electronic device 100.

[0102] Therefore, the existing electronic devices cannot achieve both charging efficiency and thinness when charged at high power, resulting in low charging efficiency of the existing electronic devices when charged at high power.

[0103] As described in the background technology, taking a mobile phone as an example, a charging power greater than or equal to 35w is generally called high-power charging; a charging power less than 35w is called normal-power charging or low-power charging.

[0104] It should be noted that, due to the different types of electronic devices, the definition of the power for high-power charging of electronic devices may also be different. Therefore, in this application, there is no absolute limitation on the power for high-power charging of electronic devices.

[0105] The structure of the electronic device components described above is further described below using a mobile phone as an example.

[0106] In order to solve the technical problem that existing electronic devices cannot achieve both charging efficiency and thinness when charged at high power, an embodiment of the present application proposes a protective case 200 and an electronic device assembly, and the electronic device assembly includes the electronic device 100 and the protective case 200 mentioned above. Figure 3 FIG. 2 shows a schematic diagram of a structure in which a protective shell 200 is installed on an electronic device 100. Figure 3 As shown, the protective shell 200 can be arranged on the side of the electronic device 100 provided with the back cover 12. When the protective shell 200 is installed on the electronic device 100 and the electronic device 100 needs to be charged, the side of the electronic device 100 provided with the protective shell 200 can be directed toward the charging base (not shown), so that the wireless charging function of the electronic device 100 can be realized, and the charging efficiency of the electronic device 100 during high-power charging can be improved to realize fast charging of the electronic device 100. In addition, the provision of the protective shell 200 can also facilitate the thinning of the electronic device 100.

[0107] The structure of the electronic device assembly is further described below with reference to the accompanying drawings.

[0108] Figure 4 Shown from another perspective Figure 3 Schematic diagram of the installation of the protective shell 200 on the electronic device 100. Figure 4As shown, the protective shell 200 includes a protective shell body 210. The electronic device 100 includes a shell 1. The protective shell body 210 is constructed to be arranged on the outer surface of the shell 1 when the electronic device 100 and the protective shell 200 are installed together, so that by setting the protective shell body 210 on the shell 1, the installation and connection of the protective shell 200 on the electronic device 100 can be realized, and the protective function of the protective shell 200 on the electronic device 100 can be realized. Among them, the protective shell body 210 can be installed on the outer surface of the shell 1 by snapping, clamping or other methods to realize the detachable installation of the protective shell 200 and the electronic device. In the present application, the installation method of the protective shell body 210 on the shell 1 is not particularly limited.

[0109] See again Figure 2 As described above, the housing 1 may include a middle frame 11 and a back cover 12 provided on one side of the middle frame 11. The outer surface of the housing 1 may be understood as the surface of the middle frame 11 and the back cover 12 exposed on the electronic device 100. The protective shell body 210 may be a contoured structure adapted to the shape of the outer surface of the housing 1, so that when the protective shell body 210 is provided on the outer surface of the housing 1, it can also have a good adaptation effect with the housing 1, so as to avoid the protective shell body 210 affecting the use of the electronic device 100. The structure of the protective shell body 210 and its arrangement on the housing 1 will be further described below in conjunction with specific drawings.

[0110] Figure 5 A schematic diagram of the structure of a protective shell 200 is shown. Figure 6 Shows Figure 4 A partial cross-sectional view of an electronic device component in the AA direction. Figure 5 As shown, the protective shell 200 further includes a first receiving coil 220 and a contact point 231. Figure 6 Combined with Figure 5 As shown, the first receiving coil 220 is located in the protective shell body 210 , and the first receiving coil 220 is connected to the contact point 231 .

[0111] The first receiving coil 220 can take various forms, such as a wound coil, a planar coil formed on a flexible circuit board, or any other form, so as to improve the charging efficiency of the electronic device 100 during high-power charging while making the structure of the first receiving coil 220 more diversified to adapt to the structural design of the protective case 200.

[0112] When the first receiving coil 220 is a wound coil, the first receiving coil 220 may be formed by coil winding.

[0113] When the first receiving coil 220 is a flexible circuit board coil, a ring circuit can be formed on the substrate of the flexible circuit board by etching or other methods, thereby forming the first receiving coil 220. The planar coil formed on the flexible circuit board can be referred to as a flexible circuit board coil. The ring circuit can be understood as a planar coil on the flexible circuit board.

[0114] The shape of the first receiving coil 220 can be circular, directional or other shapes. In the present application, the structure and shape of the first receiving coil 220 are not limited.

[0115] The structure of the electronic device component is further described below by taking a circular flexible circuit board coil as an example.

[0116] As described above, the electronic device 100 further includes a circuit board located in the housing 1. Figure 6 The circuit board can be located in a housing cavity (not shown) surrounded by the back cover 12 and the middle frame 11 in the housing 1. In the present application, the circuit board has a charging circuit 21. The charging circuit 21 has a charging contact 2104 so that the protective shell 200 is connected to the charging contact 2104 through the contact contact 231. The charging circuit 21 can refer to the structure of the existing electronic device 100 and will not be further described here.

[0117] Continue to see Figure 6 , the contact contact 231 and the charging contact 2104 are correspondingly arranged on the side of the protective shell body 210 facing the shell 1. When the electronic device 100 and the protective shell 200 are installed together, the contact contact 231 contacts the charging contact 2104. Since the charging contact 2104 is connected to the charging circuit 21, the contact contact 231 is connected to the first receiving coil 220. Therefore, when the contact contact 231 contacts the charging contact 2104, the first receiving coil 220 can be connected to the charging circuit 21 through the contact contact 231 and the charging contact 2104, and form a complete wireless charging system with the charging circuit 21. In this way, when the side of the electronic device 100 equipped with the protective shell 200 is placed on the charging base (not shown), the wireless charging function of the electronic device 100 can be realized.

[0118] See again Figure 6As shown, the first receiving coil 220 has two ends. The two ends can be regarded as the starting end and the end of the first receiving coil 220, respectively. The two ends of the first receiving coil 220 can be connected to a contact contact 231 through a lead 250, etc. Correspondingly, the charging circuit 21 also has two charging contacts 2104, and the two charging contacts 2104 correspond to a contact contact 231 respectively. When the protective shell body 210 is arranged on the outer surface of the shell 1, the contact contact 231 contacts the corresponding charging contact 2104, so that the two ends of the first receiving coil 220 can be connected to the charging circuit 21 through the corresponding contact contacts 231 and the charging contacts 2104, and form a complete wireless charging system with the charging circuit 21.

[0119] When the first receiving coil 220 is the winding coil mentioned above, the winding start end of the coil can form the starting end of the first receiving coil 220, and the winding end of the coil can form the end of the first receiving coil 220. When the first receiving coil 220 is the flexible circuit board coil mentioned above, the starting end of the loop circuit on the flexible circuit board can serve as the starting end of the first receiving coil 220, and the end of the loop circuit can serve as the end of the first receiving coil 220.

[0120] Compared with the existing electronic devices mentioned above, since the first receiving coil 220 is located in the protective shell body 210, the thickness of the first receiving coil 220 is not limited by the electronic device 100, so that the first receiving coil 220 can have a larger thickness and a smaller impedance. Therefore, when the electronic device 100 and the protective shell 200 are installed together, the defects caused by the limited thickness of the receiving coil mentioned above can be overcome, the charging efficiency of the electronic device 100 during high-power charging is improved, and the electronic device 100 can be quickly charged during high-power charging, so that the user can get a faster charging experience.

[0121] Furthermore, compared to the above-mentioned existing electronic devices, since the first receiving coil 220 is located in the protective shell body 210, while ensuring the wireless charging function of the electronic device 100, the existence of the first receiving coil 220 can also be prevented from affecting the thickness of the electronic device 100, which is conducive to the thinness of the electronic device 100.

[0122] In order to realize the wireless charging function of the electronic device 100, the charging circuit 21 usually has high-power devices, and the device height of these devices is relatively large compared to the coil thickness of the first receiving coil 220, generally close to 1 mm. Therefore, the present application sets the charging circuit 21 in the electronic device 100, which can avoid the charging circuit 21 affecting the thickness of the protective shell 200, and is conducive to the thinning of the protective shell 200.

[0123] Figure 7 Shows Figure 4 A cross-sectional view of an electronic device assembly in the BB direction. Figure 7 As shown, as described above, the housing 1 includes a middle frame 11 and a back cover 12 covering the middle frame 11. When the electronic device 100 and the protective shell 200 are installed together, at least part of the protective shell body 210 covers the back cover 12. In addition, the position of the first receiving coil 220 corresponds to the back cover 12. Since the back cover 12 has a larger layout area than the middle frame 11, when the first receiving coil 220 is located in the position corresponding to the protective shell body 210 and the back cover 12, the first receiving coil 220 can have a larger layout area on the protective shell body 210, so as to realize the arrangement of the first receiving coil 220 in the protective shell body 210.

[0124] Continue to see Figure 7 The protective shell body 210 may include a protective cover plate 211 and a protective side plate 212 arranged around the protective cover plate 211. The protective cover plate 211 and the protective side plate 212 may be integrally formed to enhance the connection strength between the protective cover plate 211 and the protective side plate 212. Alternatively, the protective cover plate 211 and the protective side plate 212 may also be connected by bonding or other means. In the present application, the connection between the protective cover plate 211 and the protective side plate 212 is not limited.

[0125] When the electronic device 100 and the protective case 200 are installed together, the protective cover plate 211 covers the back cover 12, and the protective side plate 212 is located on the side of the middle frame 11 and covers at least part of the side of the middle frame 11. For example, the protective side plate 212 can cover the entire circumferential outer wall of the middle frame 11 to achieve full coverage of the housing 1 by the protective case body 210. For another example, the protective side plate 212 can also cover part of the circumferential outer wall of the middle frame 11. In the present application, there is no special limitation on the coverage range of the protective side plate 212 on the middle frame 11.

[0126] The protective side plate 212 can be installed on the side of the middle frame 11 in a detachable manner such as snapping, so that the protective shell body 210 can be arranged on the outer surface of the shell 1 while the protective shell 200 can be installed on the electronic device 100.

[0127] Moreover, by providing the protective cover plate 211 and the protective side plate 212, the protective shell body 210 can also form a contoured structure that matches the outer surface structure of the shell 1, so that the side of the protective shell body 210 facing the shell 1 has a good fit with the shell 1, so that the back cover 12 and the middle frame 11 can be better received in the protective shell body 210, thereby enhancing the protective effect of the protective shell body 210 on the back cover 12 and the middle frame 11.

[0128] It should be noted that, in some embodiments, on the basis of ensuring that the protective cover plate 211 itself can be installed on the housing 1, the protective shell body 210 may also only include the protective cover plate 211. In the present application, the structure of the protective shell body 210 is not particularly limited.

[0129] The structure of the electronic device assembly is further described below by taking the protective case body 210 including the protective cover plate 211 and the protective side plate 212 as an example.

[0130] See again Figure 1 and Figure 3 , the middle frame 11 of the electronic device 100 is usually provided with buttons, or the middle frame 11 of the electronic device 100 is usually also provided with sound holes for speakers and plug interfaces for electrical connectors. In order to prevent the protective case 200 from affecting the use of the electronic device 100, the protective side panels 212 can be provided with avoidance treatment at the parts corresponding to the buttons, sound holes and plug interfaces. For example, the protective side panels 212 can be provided with avoidance holes or avoidance grooves at the corresponding buttons. In the present application, the avoidance treatment method adopted by the protective side panels 212 is not limited.

[0131] The first receiving coil 220 is located in the protective cover 211. Compared with the protective side plate 212, when the first receiving coil 220 is located in the protective cover 211, the first receiving coil 220 can have a larger layout area on the protective shell body 210, so as to realize the arrangement of the first receiving coil 220 in the protective shell body 210.

[0132] Continue to see Figure 7 A first slot (not shown) is disposed on the side of the protective cover 211 facing the housing 1 . The first receiving coil 220 can be embedded in the first slot to achieve the arrangement of the first receiving coil 220 in the protective cover 211 .

[0133] The shape of the first slot body is adapted to the shape of the first receiving coil 220. For example, when the shape of the first receiving coil 220 is circular, the shape of the first slot body can also be circular, so that on the basis of the first receiving coil 220 being embedded in the first slot body, not only can the shape of the first slot body and the first receiving coil 220 have a high degree of fit, which is conducive to reducing the opening area on the protective cover 211, but also the first slot body can be used to limit the movement of the first receiving coil 220 on the XY plane. The XY plane is a plane formed by the width direction X and the length direction Y of the electronic device 100.

[0134] The radius of the first slot body can be greater than the outer diameter of the first receiving coil 220, so that the first receiving coil 220 can be smoothly embedded in the first slot body. To prevent the first receiving coil 220 from falling off from the first slot body, the first receiving coil 220 can also be connected to the protective cover plate 211 in the first slot body by bonding or other means to enhance the fixing effect of the first receiving coil 220 in the first slot body.

[0135] In other embodiments, the first receiving coil 220 may also be integrally formed in the protective cover 211. For example, the first receiving coil 220 may be integrally formed in the protective cover 211 by an injection molding process, so that the first receiving coil 220 can form an integral piece with the protective cover 211, thereby improving the connection strength between the first receiving coil 220 and the protective cover 211. In the present application, the fixing method of the first receiving coil 220 in the protective cover 211 is not limited.

[0136] The structure of the protective shell 200 is further described below by taking the first receiving coil 220 embedded in the first slot as an example.

[0137] Continue to see Figure 7 , a magnetic member 240 is further provided in the protective shell 200, and the magnetic member 240 is assembled with the protective shell body 210 so that the magnetic member 240 and the protective shell 200 are relatively fixed. When the electronic device 100 and the side with the protective shell 200 installed are placed on a charging base (not shown), the protective shell 200 can be magnetically adsorbed on the charging base through the magnetic member 240, so that the user can get the experience of magnetic wireless charging, which helps to improve the user experience.

[0138] The charging base is generally provided with a charging area, and the magnetic core and transmitting coil mentioned above are both located in the charging area. The magnetic member 240 is constructed to be able to magnetically adsorb with the magnetic core in the charging base, so that the user can experience magnetic wireless charging. At the same time, the magnetic member 240 can also be used to align the position of the first receiving coil 220 on the charging base, so that when the side of the electronic device 100 equipped with the protective case 200 is placed on the charging base, it is just adsorbed on the charging area of ​​the charging base for the convenience of the user.

[0139] Continue to see Figure 7 Combined with Figure 5 , the magnetic member 240 can be a magnet or other structure that can be magnetically attracted to the magnetic core. The number of the magnetic member 240 can be one, and the magnetic member 240 is annularly surrounded on the outer side of the first receiving coil 220. For example, the magnetic member 240 can be an annular magnet or other annular structure that can be magnetically attracted to the magnetic core. The magnetic member 240 surrounds the outer side of the first receiving coil 220, and the first receiving coil 220 is located in the protective cover 211, so the magnetic member 240 can also be located in the protective cover 211.

[0140] The number of magnetic members 240 may be multiple. For example, the number of magnetic members 240 may be two, three, four, etc. Multiple magnetic members 240 are arranged at intervals on the circumferential outer side of the first receiving coil 220. In the present application, the number and structure of the magnetic members 240 of the present application are not limited, so as to increase the diversity of the structure of the protective shell.

[0141] Compared with the arrangement of multiple magnetic parts 240 , the arrangement of the annular structure of the magnetic part 240 can enable the magnetic part 240 and the magnetic core of the charging base to have a larger magnetic attraction area, so that the user can obtain a better magnetic attraction experience, while also simplifying the structure of the magnetic part 240 and the protective shell 200 .

[0142] Continue to see Figure 7 , the magnetic member 240 can be located inside the protective shell body 210 to achieve the assembly of the magnetic member 240 and the protective shell body 210. At this time, the magnetic member 240 can be integrally formed in the protective shell body 210. For example, the magnetic member 240 can be integrally formed in the protective shell body 210 by an injection molding process, so that the magnetic member 240 can form an integral part with the protective shell body 210, thereby improving the connection strength between the magnetic member 240 and the protective shell body 210.

[0143] Figure 8 A cross-sectional view of an electronic device component is shown. Figure 4 BB section in. See Figure 8 As shown, in other embodiments, the magnetic member 240 may also be embedded on a side of the protective shell body 210 away from the electronic device 100, that is, the magnetic member 240 may also protect the outside of the shell body 210. By embedding the magnetic member 240 on the protective shell body 210, while realizing the assembly of the magnetic member 240 and the protective shell body 210, the magnetic member 240 is located on the side of the protective shell body 210 away from the electronic device 100, so that the magnetic member 240 and the magnetic core in the charging base are magnetically adsorbed.

[0144] Continue to see Figure 8 , an embedding groove 2111 may be provided on the protective shell body 210 to enable the assembly of the magnetic part 240 in the protective shell 200. The embedding groove 2111 may be located on the side of the protective cover 211 away from the shell 1, so that when the magnetic part 240 is embedded in the embedding groove 2111, the protective shell 200 can be better adsorbed on the magnetic core of the charging base. The shape of the embedding groove 2111 is adapted to the shape of the magnetic part 240. Taking the annular structure of the magnetic part 240 as an example, the embedding groove 2111 may be an annular groove with the same shape as the magnetic part 240. In this way, while ensuring that the magnetic part 240 can be embedded in the embedding groove 2111, the opening area of ​​the protective shell 200 can be reduced.

[0145] The structure of the electronic device assembly is further described below by taking the example of the magnetic member 240 being integrally formed in the protective shell body 210 .

[0146] See again Figure 7 As shown, the charging contact 2104 is exposed on the outer surface of the housing 1. When the electronic device 100 and the protective housing 200 are installed together, the contact 231 elastically abuts against the charging contact 2104 to connect the first receiving coil 220 to the charging circuit 21.

[0147] Furthermore, the elastic contact between the contact point 231 and the charging contact 2104 can enhance the conduction effect between the contact point 231 and the charging contact 2104 and enhance the stability of the conduction between the first receiving coil 220 and the charging circuit 21 .

[0148] It should be noted that, in some embodiments, the charging contact 2104 can also be located inside the housing 1 on the basis of ensuring that the contact 231 can be connected to the charging contact 2104. In the present application, the position of the charging contact 2104 on the electronic device 100 is not further limited.

[0149] The structure of the electronic device assembly is further described below by taking the charging contact 2104 located on the housing 1 as an example.

[0150] Continue to see Figure 7 The protective shell 200 further includes an elastic conductive member 230 connected to the first receiving coil 220, and the elastic conductive member 230 is located in the protective shell body 210. The elastic conductive member 230 can be pre-buried (pre-embedded) in the protective shell body 210 during the manufacturing process of the protective shell body 210, and connected to the end of the first receiving coil 220 through the lead 250. In this way, not only can the fixing effect of the elastic conductive member 230 on the protective shell body 210 be enhanced, but also the lead 250 can be hidden in the protective shell body 210 to enhance the aesthetics of the protective shell body 210.

[0151] Continue to see Figure 7 , the elastic conductive member 230 can be located on the side of the first receiving coil 220 to avoid the setting of the elastic conductive member 230 affecting the arrangement of the first receiving coil 220 in the protective shell body 210. Alternatively, when the protective shell body 210 has available space in the area surrounded by the first receiving coil 220, the elastic conductive member 230 can also be located in the available space. In the present application, the setting position of the elastic conductive member 230 in the protective shell body 210 is not particularly limited.

[0152] Part of the elastic conductive member 230 is exposed on the side of the protective shell body 210 facing the housing 1, and forms a contact point 231. In this way, by setting the elastic conductive member 230, the contact point 231 is formed on the surface of the protective shell body 210, and the elastic contact between the contact point 231 and the charging contact 2104 is achieved. At the same time, the elastic conductive member 230 can be hidden in the protective shell body 210, thereby enhancing the aesthetics of the protective shell 200.

[0153] The two ends of the first receiving coil 220 are respectively connected to an elastic conductive member 230 , so as to form two contact points 231 on the surface of the protective shell body 210 .

[0154] The elastic conductive member 230 includes at least one of a metal spring and an elastic ejector. For example, both elastic conductive members 230 can be metal springs or elastic ejector. For another example, one of the two elastic conductive members 230 can be a metal spring, and the other can be an elastic ejector. This makes the selection of the elastic conductive member 230 and the structural form of the protective shell 200 more diverse. In the present application, the structure of the elastic conductive member 230 is not further limited.

[0155] As described above, the circuit board includes a main circuit board 2 and a sub-circuit board 3 electrically connected to the main circuit board 2. Figure 2 As shown, the main circuit board 2 and the auxiliary circuit board 3 are located at opposite ends of the middle frame 11. The main circuit board 2 can be located on one side of the top frame of the middle frame 11. The auxiliary circuit board 3 is located on one side of the bottom frame of the middle frame 11 and is electrically connected to the main circuit board 2 through a flexible circuit board so as to connect the auxiliary circuit board 3 with the main circuit board 2.

[0156] The main circuit board 2 has a charging circuit 21 to prevent the charging circuit 21 from affecting the thickness of the protective shell 200 , so that the protective shell 200 has the characteristics of being light and thin.

[0157] The charging contacts 2104 can be arranged on the outer surface of the shell 1 corresponding to the main circuit board 2 or the auxiliary circuit board 3. In this way, while the first receiving coil 220 is connected to the charging circuit 21 through the contact contacts 231 and the charging contacts 2104, the setting position of the charging contacts 2104 in the electronic device 100 can be more diversified.

[0158] The possible arrangement positions of the charging contacts 2104 are further described below in conjunction with the accompanying drawings.

[0159] See again Figure 6 and Figure 7 In some embodiments, when the charging contact 2104 is arranged corresponding to the main circuit board 2, the charging contact 2104 can be located at a position where the back cover 12 or the middle frame 11 is opposite to the main circuit board 2.

[0160] For example, see again Figure 6 The charging contact 2104 can be located at a position on the back cover 12 corresponding to the edge area of ​​the main circuit board 2. At this time, the contact contact 231 can be located at a position on the protective cover 211 opposite to the charging contact 2104.

[0161] For example, see again Figure 7 The charging contact 2104 can be located on the right side frame of the middle frame 11 opposite to the main circuit board 2. At this time, the contact 231 can be located on the protective side plate 212 opposite to the charging contact 2104.

[0162] Regardless of whether the contact point 231 is located at a position corresponding to the charging contact point 2104 on the protective cover plate 211 or the protective side plate 212, the first receiving coil 220 and the charging circuit 21 can be connected through the elastic contact between the contact point 231 and the charging contact point 2104. The difference is that since the first receiving coil 220 is located on the protective cover plate 211, when the contact point 231 is located on the protective cover plate 211, compared with the arrangement in which the contact point 231 is located on the protective side plate 212, the lead 250 between the contact point 231 and the first receiving coil 220 can be shortened.

[0163] Since the protective shell body 210 is buckled onto the side of the middle frame 11 through the protective side plate 212, when the contact point 231 is located on the protective side plate 212, compared with the arrangement in which the contact point 231 is located on the protective cover plate 211, the stability of the contact point 231 and the charging contact 2104 when they are connected can be enhanced.

[0164] Fig. 9 Shows Figure 4 A partial cross-sectional view in the CC direction. Fig. 9 As shown, in some embodiments, when the charging contact 2104 is arranged corresponding to the auxiliary circuit board 3, the charging contact 2104 can be located at a position where the middle frame 11 is opposite to the auxiliary circuit board 3. For example, the charging contact 2104 can be located on the bottom frame of the middle frame 11. At this time, the contact contact 231 can be located at a position of the protective side plate 212 corresponding to the charging contact 2104, so that the contact contact 231 and the charging contact 2104 can be connected while the contact contact 231 and the charging contact 2104 are in contact and conductive, and the contact contact 231 and the charging contact 2104 can also obtain better electrical connection stability. In the present application, the positions of the charging contacts 2104 and the contact contacts 231 are not particularly limited.

[0165] Continue to see Fig. 9As shown, the charging circuit 21 has an electrode 2103, and the electrode 2103 is located in the housing 1. The portion of the electrode 2103 exposed on the outer surface of the housing 1 forms a charging contact 2104, and the end of the electrode 2103 extends toward the inside of the housing 1 and is located on the circuit board, so that the arrangement of the electrode 2103, while forming the charging contact 2104 on the outer surface of the housing 1, can also connect the first receiving coil 220 to the charging circuit 21.

[0166] Continue to see Fig. 9 As shown, the shell 1 is provided with a through hole (not marked) at the position corresponding to the electrode 2103, and the end of the electrode 2103 away from the circuit board is passed through the through hole and exposed on the outer surface of the shell 1, so that the electrode 2103 can be arranged in the shell 1 while forming a charging contact 2104 on the outer surface of the shell 1.

[0167] The through-hole is an opening that matches the shape of the electrode 2103. Exemplarily, the shape of the through-hole may include, but is not limited to, a circular opening, a rectangular opening, etc. The electrode 2103 may be interference fit with the through-hole, or the electrode 2103 may also be connected to the housing 1 by bonding or other means to fix the electrode 2103 in the through-hole. In some embodiments, the electrode 2103 may also be pre-buried in the housing 1 during the manufacturing process of the housing 1. In the present application, the shape of the through-hole and the assembly method of the electrode 2103 in the through-hole are not further limited.

[0168] It should be noted that the position of the through hole is different depending on the position of the electrode 2103. For example, when the electrode 2103 is located on the main circuit board 2, the through hole can be located at the position of the right side frame of the back cover 12 or the middle frame 11 corresponding to the electrode 2103. For another example, when the electrode 2103 is located on the auxiliary circuit board 3, the through hole can be located at the position of the bottom frame of the middle frame 11 corresponding to the electrode 2103.

[0169] The portion of the electrode 2103 exposed on the outer surface of the shell 1 can be smoothly connected to the outer surface of the shell 1 to avoid the presence of the charging contact 2104 affecting the smoothness of the outer surface of the shell 1 at the charging contact 2104 .

[0170] It should be noted that the electronic device 100 may also have a circuit board, which may take into account at least some of the functions of the main circuit board 2 and the auxiliary circuit board 3. For example, the main circuit board 2 and the auxiliary circuit board 3 may form a circuit board, so that the formed circuit board can take into account the functions of the main circuit board 2 and the auxiliary circuit board 3 at the same time. At this time, the setting position of the charging contact 2104 on the circuit board can refer to the relevant description of the charging contact 2104 on the main circuit board 2 and the auxiliary circuit board 3 above, which will not be repeated here.

[0171] Continue to see Fig. 9 , the electronic device assembly may further include a magnetic shielding member 260. When the electronic device 100 and the protective case 200 are installed together, the magnetic shielding member 260 may be located between the first receiving coil 220 and the charging circuit 21, and cover the first receiving coil 220, so as to block the magnetic field generated by the transmitting coil in the charging base from being transmitted to the charging circuit 21, so as to avoid the magnetic field generated by the transmitting coil from affecting the charging circuit 21, thereby ensuring the normal use of the wireless charging function of the electronic device 100.

[0172] The magnetic isolation member 260 may be a layered structure including nanocrystals, ferrites or other materials with magnetic resistance. In the present application, the material of the magnetic isolation member 260 is not further limited. Nanocrystals may include but are not limited to metal nanocrystals, semiconductor nanocrystals, inorganic non-metallic or organic polymer nanocrystals. The magnetic isolation member 260 may be a nanocrystal layer formed by one or at least two nanocrystals. By setting nanocrystals or ferrites, the property of nanocrystals or ferrites that can block magnetic force penetration can be utilized to block the magnetic field generated by the transmitting coil from being transmitted to the charging circuit 21.

[0173] The magnetic shielding member 260 may be located in at least one of the protective case 200 and the electronic device 100, so that the magnetic shielding member 260 blocks the magnetic field generated by the transmitting coil from being transmitted to the charging circuit 21, and the magnetic shielding member 260 can be arranged in a more diversified position in the electronic device assembly to adapt to different electronic devices 100 and protective cases 200. The projection of the first receiving coil 220 on the magnetic shielding member 260 is located in the magnetic shielding member 260, so that the barrier can completely cover the first receiving coil 220.

[0174] Fig. 9 FIG. 2 shows a structure in which the magnetic isolation member 260 is located inside the protective shell 200. Fig. 9 As shown, when the magnetic shielding member 260 is located in the protective shell 200, the protective shell body 210 is provided with a second slot (not shown) on the side facing the shell 1. The magnetic shielding member 260 is embedded in the second slot and covers the side of the first receiving coil 220 facing the shell 1, so that the magnetic shielding member 260 is arranged in the protective shell body 210 through the arrangement of the second slot. The second slot can be located in the protective cover plate 211 and on the side of the first receiving coil 220 facing the back cover 12, so that when the magnetic shielding member 260 is located in the second slot, it can be located between the first receiving coil 220 and the charging circuit 21.

[0175] The surface of the magnetic shielding member 260 is flush with the side of the protective shell body 210 facing the shell 1 , which not only helps to make the protective shell 200 lighter and thinner, but also prevents the setting of the magnetic shielding member 260 from affecting the flatness of the protective shell body 210 on the side facing the shell 1 .

[0176] See also Fig. 9 As shown, the second slot body can be connected to the first slot body on the protective shell body 210, and the magnetic shielding member 260 is attached to the side of the first receiving coil 220 facing the shell 1, so that the magnetic shielding member 260 covers the first receiving coil 220. Specifically, the second slot body is located on the side of the first slot body facing the shell 1 along the thickness direction Z of the electronic device 100, and the length and width of the second slot body are greater than or equal to the first slot body, so that the magnetic shielding member 260 can be completely located in the second slot body and completely cover the first receiving coil 220, thereby achieving a better barrier effect. The direction where the length of the second slot body is parallel to the width direction X of the electronic device 100, and the direction where the width of the second slot body is parallel to the length direction Y of the electronic device 100.

[0177] The shape of the second slot is the same as that of the magnetic shielding member 260. For example, the magnetic shielding member 260 may be circular, rectangular or in other shapes, and in the present application, the shape of the magnetic shielding member 260 is not further limited. In order to enhance the fixing effect of the magnetic shielding member 260 in the protective shell body 210, when the magnetic shielding member 260 is in the second slot, it may be further connected to the protective shell body 210 by bonding or other means.

[0178] In some embodiments, the second slot body may also be spaced apart from the first slot body along the thickness direction Z of the electronic device 100 , so that when the magnetic shielding member 260 is located in the second slot body, it can also cover the first receiving coil 220 .

[0179] Alternatively, in some other embodiments, the magnetic isolation member 260 may also be integrally formed in the protective cover 211. In the present application, the arrangement of the magnetic isolation member 260 in the protective cover 211 is not limited.

[0180] Fig.10 A cross-sectional view of another electronic device component is shown. Figure 4 BB section in. See Fig.10 As shown, the magnetic isolation member 260 is located on the main circuit board 2 or in the gap between the main circuit board 2 and the back cover 12, and covers the first receiving coil 220. This can further reduce the thickness of the protective shell 200 and enhance the lightweight design of the protective shell 200. At the same time, since the magnetic isolation member 260 can also share part of the thickness with some modules on the main circuit board 2, the setting of the magnetic isolation member 260 can be avoided to affect the lightweight design of the electronic device 100.

[0181] The present application arranges the first receiving coil 220 in the protective shell 200 and arranges the charging circuit 21 on the main circuit board 2, thereby improving the charging efficiency of the electronic device 100 during high-power charging to achieve fast charging of the electronic device 100 while also meeting the requirements of making the electronic device 100 thin and light.

[0182] In other embodiments, the magnetic shielding member 260 is also located in the protective shell 200 of the electronic device component and the electronic device 100. In the present application, there is no limitation on the location of the magnetic shielding member 260 in the electronic device 100, as long as the magnetic shielding member 260 can cover the first receiving coil 220 and block the magnetic field generated by the transmitting coil from being transmitted to the charging circuit 21.

[0183] However, in some scenarios, the user not only requires the electronic device 100 itself to have a wireless charging function, but also needs to improve the charging efficiency of the electronic device 100 when charging at high power.

[0184] To this end, in the present application, another electronic device 100 is proposed. For the convenience of description, the electronic device 100 mentioned above is referred to as the first electronic device, and the other electronic device 100 to be mentioned below is referred to as the second electronic device. The difference from the first electronic device is that the second electronic device has a second receiving coil 6 so that the second electronic device itself has a wireless charging function to meet the user's needs in different scenarios. For example, in a scenario where the user has high requirements for the wireless charging rate of the electronic device 100, the protective case 200 can be set on the second electronic device to achieve fast charging during high-power charging. For example, in a scenario where the user does not have too high requirements for the wireless charging rate of the electronic device 100, the second electronic device can be used alone to achieve the wireless charging function.

[0185] The structures of the second electronic device and the electronic device assembly including the second electronic device are further described below in conjunction with the accompanying drawings.

[0186] Fig.11 A cross-sectional view of another electronic device component is shown. Figure 4 BB section in. See Fig.11 In some embodiments, the second electronic device may further include a second receiving coil 6 that is electrically connected to the charging circuit 21, and the second receiving coil 6 is located in the housing 1. For example, the second receiving coil 6 may be located in the housing 1 at a position opposite to the first receiving coil 220. In the present application, the position of the second receiving coil 6 is not limited. The second receiving coil 6 also has two ends, and the two ends of the second receiving coil 6 are electrically connected to the charging circuit 21, so that the second receiving coil 6 can also form a complete wireless charging system with the charging circuit 21 to realize the wireless charging function of the second electronic device itself. The way in which the two ends of the second receiving coil 6 are electrically connected to the charging circuit 21 can refer to the relevant settings in the existing electronic device 100, and is not limited here.

[0187] The structure of the second receiving coil 6 is the same as that of the first receiving coil 220 . For details, please refer to the above description of the first receiving coil 220 , which will not be repeated here.

[0188] The thickness of the second receiving coil 6 is smaller than that of the first receiving coil 220 , so that when the protective shell 200 is set on the second electronic device, the second receiving coil 6 can be connected to the charging circuit 21 to achieve fast charging of the second electronic device during high-power charging.

[0189] Furthermore, since the thickness of the second receiving coil 6 is smaller than that of the first receiving coil 220 , the second receiving coil 6 can be prevented from affecting the thickness of the electronic device 100 , so as to make the electronic device 100 lighter and thinner.

[0190] Compared with the second receiving coil 6, the first receiving coil 220 not only has a larger thickness and a smaller impedance, but also the resistance value of the first receiving coil 220 is different from that of the second receiving coil 6, so that the second electronic device can confirm whether the installation status of the protective case 200 on the second electronic device based on the difference between the first receiving coil 220 and the second receiving coil 6, so as to connect the second receiving coil 6 with the charging circuit 21 when the protective case 200 is on the outer surface of the shell 1 of the second electronic device.

[0191] The housing 1 also has a controller 7 and a switch 8. The controller 7 may include but is not limited to the processor module, SoC, etc. mentioned above. In the present application, the type of controller 7 is not limited. The switch 8 is located between the first receiving coil 220 and the second receiving coil 6 and is electrically connected to the controller 7. The controller 7 is configured to control the switch 8 after determining that the protective shell 200 is in an installation state installed together with the electronic device 100, so that the first receiving coil 220 is connected to the charging circuit 21, so as to realize that the second electronic device has its own wireless charging function. When the user has a high requirement for the charging rate of the second electronic device during high-power charging, the second electronic device can also be installed together with the protective shell 200. Under the control of the controller 7, the second electronic device can also be automatically and quickly charged during high-power charging to meet the user's use requirements for the second electronic device in different scenarios.

[0192] When the protective shell 200 is in the installation state mentioned above, the protective shell 200 is arranged on the outer surface of the housing 1, and the first receiving coil 220 contacts the charging contact 2104 through the contact 231. Therefore, when the controller 7 determines that the protective shell 200 is in the installation state, it can also be understood that the controller 7 determines the insertion of the first receiving coil 220 in the charging circuit 21.

[0193] The following further describes the arrangement position of the switch 8 between the first receiving coil 8 and the second receiving coil 6 in combination with different embodiments.

[0194] Example 1

[0195] Fig.12 A schematic diagram showing a connection between the first receiving coil 220 and the second receiving coil 6 and the charging circuit 21 is shown. Fig.12 As shown, the switch 8 is respectively connected to the first receiving coil 220, the second receiving coil 6 and the charging circuit 21. When the second electronic device is not provided with a protective case 200 or is provided with a traditional protective case, the control switch 8 connects the second receiving coil 6 and the charging circuit 21, and the wireless charging function of the second electronic device itself at high power can also be realized, but the charging efficiency is poorer than that of the second electronic device with the protective case 200 installed.

[0196] If the charging rate of the second electronic device during high-power charging needs to be increased, the protective case 200 can be installed together with the second electronic device. The controller 7 is configured to control the switch 8 to disconnect the second receiving coil 6 from the charging circuit 21 and connect the first receiving coil 220 to the charging circuit 21 after determining that the protective case 200 is in the installation state mentioned above, so that the wireless charging system composed of the first receiving coil 220 and the charging circuit 21 can be realized under the control of the controller 7 after the protective case 200 and the second electronic device are installed together, so that the second electronic device can be automatically and quickly charged during high-power charging, so that the user can get a faster charging experience.

[0197] The switch 8 may be a single-pole double-throw switch or other switching switches capable of implementing a switching function, so as to control the conduction state of the first receiving coil 220 and the second receiving coil 6 and the charging circuit 21 .

[0198] The structure of the switch 8 is further described below by taking a single-pole double-throw switch as an example. The switch 8 has two fixed ends 81 and a moving end 82. The first receiving coil 220 and the second receiving coil 6 are respectively connected to a fixed end 81, and the moving end 82 is connected to the charging circuit 21, so as to realize the connection between the switch 8 and the first receiving coil 220, the second receiving coil 6 and the charging circuit 21 respectively.

[0199] The controller 7 can be connected to the moving end 82, and is configured to control the moving end 82 to switch from the fixed end 81 connected to the second receiving coil 6 to the fixed end 81 connected to the first receiving coil 220 after the controller 7 confirms that the protective shell 200 is in the installation state mentioned above, so that the second receiving coil 6 is disconnected from the charging circuit 21 while the first receiving coil 220 is connected to the charging circuit 21.

[0200] Continue to see Fig.12 , the charging circuit 21 may include a capacitor 2101 and a bridge rectifier circuit 2102 electrically connected to the battery 4 in the electronic device 100. The capacitor 2101 may include but is not limited to a CS capacitor, which may also be called a correction capacitor. One end of the first receiving coil 220 may be connected to a fixed end 81 of the switch 8. The moving end 82 of the switch 8 may be electrically connected to the first end of the bridge rectifier circuit 2102 through the capacitor 2101, and the second end of the bridge rectifier circuit 2102 is electrically connected to the other end of the first receiving coil 220. The connection between the second receiving coil 6 and the switch 8 and the charging circuit 21 can refer to the first receiving coil 220, which will not be repeated here. In this way, the induced current generated by the first receiving coil 220 or the second receiving coil 6 can be processed in turn by the capacitor 2101 and the bridge rectifier circuit 2102, and converted into direct current to charge the battery 4.

[0201] One fixed end 81 of the switch 8 can be connected between the charging contact 2104 and the charging circuit 21, so that when the protective case 200 is set on the second electronic device, the first receiving coil 220 can be connected to the fixed end 81 of the switch 8 through the contact 231 and the charging contact 2104. The other fixed end 81 of the switch 8 can be connected between the second receiving coil 6 and the charging circuit 21 to achieve the other fixed end 81 of the switch 8 and the second receiving coil 6.

[0202] Fig.12 A schematic diagram of the structure of the switch 8 at one end of the first receiving coil 220 is shown. Fig.13 shows an identification resistor 270 and a controller 7 in Fig.12 See the connection diagram of the circuit in Fig.13 As shown, a switch 8 can be respectively provided at the two ends of the first receiving coil 220, and the two switches 8 can simultaneously perform the same operation under the control of the controller 7 to control the conduction or disconnection between the second receiving coil 6 and the two ends of the first receiving coil 220 and the charging circuit 21. In the present application, the number of switches 8 is not limited.

[0203] See again Fig.13 In some embodiments, the protective shell 200 may have an identification resistor 270, and the controller 7 is configured to determine whether the protective shell 200 is in the installation state mentioned above according to the conduction state of the branch where the identification resistor 270 is located.

[0204] By setting the identification resistor 270 , the controller 7 can easily determine whether the protection shell 200 is in an installed state set on the housing 1 .

[0205] If the controller 7 and the branch where the identification resistor 270 is located are in a conducting state, the controller 7 determines that the protective case 200 is in the installation state mentioned above, so that the second receiving coil 6 is disconnected from the charging circuit 21 through the switch 8, and the first receiving coil 220 is connected to the charging circuit 21, so that the first receiving coil 220 and the charging circuit 21 form a complete wireless charging system. In this way, after the protective case 200 and the second electronic device are installed together, under the control of the controller 7, the second electronic device can be automatically and quickly charged when charging at high power, so that the user can get a faster charging experience.

[0206] It should be noted that Fig.13 2 shows the connection state where the branch where the identification resistor 270 is located is in a conducting state with the controller 7. When the branch where the identification resistor 270 is located is in a non-conducting state with the controller 7, the connection between the branch where the identification resistor 270 is located and the controller 7 is in a disconnected state.

[0207] If the controller 7 and the branch where the identification resistor 270 is located are in a non-conductive state, the controller 7 determines that the protective shell 200 is not in the installation state mentioned above, and the controller 7 does not need to control the switch 8 to perform a switching action so that the second receiving coil 6 is still conductive with the charging circuit 21.

[0208] Specifically, the identification resistor 270 can be connected to an analog to digital converter (ADC) interface of the controller 7 .

[0209] Fig.14 FIG. 2 shows a schematic diagram of another protective shell 200. Fig.14 As shown, the protective shell body 210 is provided with an identification contact 280 connected to the identification resistor 270. The two ends of the identification resistor 270 can be connected to an identification contact 280 through a lead 250 respectively. The controller 7 has a detection contact (not shown). The detection contact is exposed on the outer surface of the shell 1 and is arranged opposite to the identification contact 280. When the protective shell body 210 is in the installation state mentioned above, the identification contact 280 contacts the corresponding detection contact to achieve conduction between the identification resistor 270 and the controller 7. Among them, the identification contact 280 can be elastically abutted against the detection contact. The structure of the identification contact 280 is the same as that of the contact contact 231, and the detection contact is the same as the structure of the charging contact 2104, which will not be repeated here.

[0210] The resistance of the identification resistor 270 may correspond to (be the same as or similar to) the resistance of the first receiving coil 220. When the first receiving coil 220 has a plurality of different types, the identification resistor 270 also has different resistances. Since the resistance of the first receiving coil 220 is different from that of the second receiving coil 6, when the controller 7 is connected to the identification resistor 270, it is not only possible to confirm that the protective case 200 is in the installation state mentioned above, but also possible to identify the type of the first receiving coil 220 according to the resistance of the identification resistor 270 read.

[0211] Among them, the identification resistor 270 can also include a thermistor, so that the controller 7 can measure the temperature of the protective shell 200 of the second electronic device when charging through the change of the thermistor's own resistance, which is helpful to avoid overheating of the protective shell 200 and the second electronic device when charging.

[0212] It should be noted that when the protective case 200 with the identification resistor 270 is set on the first electronic device, the temperature of the protective case 200 can also be measured when the first electronic device is charging, which is helpful to avoid overheating of the protective case 200 and the first electronic device during charging. At this time, the first receiving coil 220 can be directly connected to the controller 7 through the identification contact 280 and the detection contact.

[0213] Fig.15 The impedance detection circuit 9 and the controller 7 are Fig.12 See the connection diagram of the circuit in Fig.15 As shown, in other embodiments, the housing 1 has an impedance detection circuit 9 electrically connected to the controller 7. The impedance detection circuit 9 is used to detect the impedance of the first receiving coil 220. The controller 7 is configured to determine whether the protective shell 200 is in the above-mentioned installation state according to the conductive state between the impedance detection circuit 9 and the first receiving coil 220.

[0214] By setting the impedance detection circuit 9, the controller 7 can easily determine whether the protective shell 200 is in the installation state mentioned above.

[0215] If the impedance detection circuit 9 and the first receiving coil 220 are in a conducting state, the controller 7 determines that the protective case 200 is in an installed state, so that the second receiving coil 6 is disconnected from the charging circuit 21 through the switch 8, and the first receiving coil 220 is connected to the charging circuit 21, so that the first receiving coil 220 and the charging circuit 21 form a complete wireless charging system. In this way, after the protective case 200 and the second electronic device are installed together, under the control of the controller 7, the second electronic device can be automatically and quickly charged during high-power charging, so that the user can get a faster charging experience.

[0216] If the impedance detection circuit 9 and the first receiving coil 220 are in a non-conductive state, the controller 7 determines that the protective case 200 is not in the installation state mentioned above, and the controller 7 does not need to control the switch 8 to perform a switching action so that the second receiving coil 6 is still conductive with the charging circuit 21, so that the second receiving coil 6 and the charging circuit 21 form a complete wireless charging system, thereby realizing the wireless charging function of the second electronic device itself.

[0217] Continue to see Fig.15 The impedance detection circuit 9 has an input terminal (not marked) and an output terminal (not marked) connected to the controller 7. After the protective shell 200 is in the installation state mentioned above, the input terminal is in contact with the contact contact 231 through the charging contact 2104. Since the output terminal is connected to the controller 7, when the protective shell 200 is set on the outer surface of the housing 1, the first receiving coil 220 can be connected to the input terminal of the impedance detection circuit 9 through the contact contact 231 and the charging contact 2104, so that the impedance detection circuit 9 detects the impedance of the first receiving coil 220.

[0218] Among them, the impedance detection circuit 9 has two input terminals, which correspond to the two ends of the first receiving coil 220 respectively, so that the two ends of the first receiving coil 220 can be connected to one input terminal of the impedance detection circuit 9 through the contact contact 231 and the charging contact 2104 respectively to form a loop.

[0219] It should be noted that there are many types of impedance detection circuits 9 , and in the present application, no further limitation is made to the impedance detection circuits 9 .

[0220] To facilitate understanding of the detection principle of the impedance detection circuit 9, Fig.16 A schematic diagram showing the connection between one impedance detection circuit 9 and the first receiving coil 220 is shown. Fig.16 The impedance detection circuit 9 is not limited thereto.

[0221] See also Fig.16 As shown, the impedance detection circuit 9 may include a first resistor R1, a second resistor R2, a third resistor R3 and a field effect transistor 91. The first end of the first resistor R1 and the first end of the second resistor R2 respectively form input ends to achieve electrical connection between the impedance detection circuit 9 and both ends of the first receiving coil 220.

[0222] The drain of the field effect transistor 91 can be represented by D, the gate of the field effect transistor 91 can be represented by G, and the source of the field effect transistor 91 can be represented by S. The second end of the first resistor R1 is electrically connected to the drain of the field effect transistor 91, and the output terminal INT is located between the second end of the first resistor R1 and the drain of the field effect transistor 91, which can be represented by INT. The second end of the second resistor R2 is electrically connected to the gate of the field effect transistor 91. The source S of the field effect transistor 91 is grounded, and the third resistor R3 is electrically connected between the second end of the second resistor R2 and the gate of the field effect transistor 91, and is grounded.

[0223] In this way, when the second electronic device is not provided with a protective shell 200 or is provided with a traditional protective shell, the third resistor R3 will pull down the drain of the field effect transistor 91, and at this time, the output terminal INT of the impedance detection circuit 9 outputs a high level. When the protective shell 200 is set on the second electronic device, the first resistor R1 and the second resistor R2 will pull up the drain of the field effect transistor 91, and at this time, the output terminal of the impedance detection circuit 9 outputs a low level. That is to say, before and after the protective shell 200 is installed on the second electronic device, the level output by the output terminal INT of the impedance detection circuit 9 will change.

[0224] The controller 7 can confirm whether the protective shell 200 is in the installation state mentioned above according to the change of the output level of the output end of the impedance detection circuit 9, and realize the detection of the impedance of the first receiving coil 220. Specifically, when the output end of the impedance detection circuit 9 outputs a low level, the controller 7 determines that the protective shell 200 is in the installation state mentioned above. At this time, the controller 7 controls the moving end 82 to switch from the fixed end 81 connected to the second receiving coil 6 to the fixed end 81 connected to the first receiving coil 220, and the first receiving coil 220 is connected to the charging circuit 21. When the output end of the impedance detection circuit 9 outputs a high level, the moving end 82 does not perform the switching action and is located at the fixed end 81 connected to the second receiving coil 6, and the second receiving coil 6 is connected to the charging circuit 21.

[0225] It should be noted that, continue to refer to Fig.16 The impedance detection circuit 9 may further include a fourth resistor R4, which is electrically connected between the second end of the first resistor R1 and the drain of the field effect transistor 91. The output end is arranged between the fourth resistor R4 and the drain of the field effect transistor 91. A power input section (VDD end) is arranged between the fourth resistor R4 and the second end of the first resistor R1, so that the impedance detection circuit 9 is electrically connected to the power supply in the second electronic device through the power input section.

[0226] See again Fig.11, when the switch 8 is located at the connection between the first receiving coil 220 and the second receiving coil 6 and the charging circuit 21, the magnetic shielding member 260 can be located in both the protective shell 200 and the second electronic device. By arranging the magnetic shielding member 260 in the protective shell 200, it is possible to prevent the magnetic field generated by the transmitting coil from being transmitted to the second receiving coil 6 and the charging circuit 21 when the first receiving coil 220 and the wireless charging coil are turned on. The arrangement of the magnetic shielding member 260 in the protective shell 200 can refer to the relevant description above, and only the arrangement of the magnetic shielding member 260 in the second electronic device is further described here.

[0227] Continue to see Fig.11 When the magnetic shielding member 260 is located in the second electronic device, the magnetic shielding member 260 can be located between the second receiving coil 6 and the main circuit board 2, or the second receiving coil 6 can also be located on the main circuit board 2 to cover the second receiving coil 6. In the present application, the structure of the magnetic shielding member 260 in the second electronic device is not limited. By covering the second receiving coil 6 in the second electronic device with the magnetic shielding member 260, the magnetic field generated by the transmitting coil can be prevented from being transmitted to the charging circuit 21.

[0228] Example 2

[0229] The difference from the first embodiment is that the first receiving coil 220 and the second receiving coil 6 are connected in parallel to the charging circuit 21 and work simultaneously, and the setting position and structure of the switch 8 are different.

[0230] The connection between the first receiving coil 220 and the second receiving coil 6 and the setting position of the switch 8 in this embodiment will be further described below in conjunction with the accompanying drawings.

[0231] Fig.17 Another schematic diagram of connecting the first receiving coil 220 and the second receiving coil 6 to the charging circuit 21 is shown. Fig.17 As shown, the switch 8 is located at the end where the first receiving coil 220 is connected to the second receiving coil 6. The controller 7 is configured to control the switch 8 to be turned on after determining that the protective case 200 is in the installation state mentioned above, so that the first receiving coil 220 is connected in parallel with the second receiving coil 6, so that the first receiving coil 220 and the second receiving coil 6 are connected in parallel on the charging circuit 21 and work simultaneously, so that after the protective case 200 and the second electronic device are installed together, under the control of the controller 7, the second electronic device can be automatically and quickly charged when charging at high power, so that the user can get a faster charging experience.

[0232] It should be noted that, in this embodiment, the second receiving coil 6 and the charging circuit 21 are always connected and are not affected by the protective shell 200 provided outside the second electronic device, and can also realize the wireless charging function of the second electronic device itself at high power.

[0233] Fig.18 The impedance detection circuit 9 and the controller 7 are shown. Fig.17 See the connection diagram of the circuit in Fig.18 As shown, the switch 8 can be a conventional single-pole single-throw switch. The single-pole single-throw switch has a fixed end 81 and a movable end 82. The fixed end 81 and the movable end 82 are both connected to the end of the first receiving coil 220 connected to the second receiving coil 6. The controller 7 can be connected to the movable end 82, so that when the controller 7 determines that the protective shell 200 is in the installation state mentioned above, it can control the movable end 82 to close with the fixed end 81, so as to connect the first receiving coil 220 with the charging circuit 21.
