[0050] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 9 as shown. Figure 1 and Figure 2 are respectively schematic structural diagrams of the protective cover 20 at different angles in some embodiments. Figure 3 is a schematic structural diagram of the protective cover 20 with the touch control cover plate 31 omitted in some embodiments. Figure 9 is a schematic structural diagram of the electronic device 10 in some embodiments. The protective cover 20 provided in this application can be used to cover the electronic device 10. The protective cover 20 can provide a structural protection function for the electronic device 10. For example, when the electronic device 10 collides with other objects, it can buffer the impact between the electronic device 10 and other objects and prevent the electronic device 10 from being damaged. When the protective cover 20 is sleeved on the electronic device 10 in this application, the whole of the protective cover 20 and the electronic device 10 is called an electronic device. The protective cover 20 can also be integrated with any applicable components such as an e-ink screen 22, a sound sensor 23, etc. to achieve more abundant functions and improve the use experience of the electronic device. Some examples of the specific settings and functions of the components integrated in the protective cover 20 will be elaborated later. The electronic device 10 involved in this application includes, but is not limited to, any applicable electronic products such as smart phones, tablet computers, etc. In this application, a smart phone is taken as an example for illustration.

[0051] In some embodiments, the protective cover 20 for sleeving on the electronic device 10 includes a plate body portion 212, and a sleeving portion 214 and a mounting portion 216 connected to opposite sides of the plate body portion 212. The mounting portion 216 surrounds the periphery of the plate body portion 212 and is connected to the plate body portion 212. The mounting portion 216 and the plate body portion 212 jointly enclose an installation space 218 for accommodating components. Components such as the ink screen 22 and the sound sensor 23 of the protective cover 20 can be accommodated in the installation space 218. When the protective cover 20 is sleeved on the electronic device 10, the plate body portion 212 is placed on the back side of the electronic device 10, for example, on the side of the electronic device 10 facing away from the display screen. The sleeving portion 214 is used to sleeve on the peripheral side of the electronic device 10 so that the protective cover 20 can be relatively fixed to the electronic device 10.

[0052] In some embodiments, the sleeving portion 214 can surround the periphery of the plate body portion 212 and be connected to the plate body portion 212. The sleeving portion 214 is used to cover the four sides of the electronic device 10 to achieve a more comprehensive effect of the protective cover 20 on the electronic device 10. In the embodiments shown in the drawings of the present application, the sleeving portion 214 is divided into four parts. The four parts of the sleeving portion 214 are respectively connected to the four corners of the plate body portion 212 and are respectively used to wrap the four corners of the side of the electronic device 10, and can also provide an effective protective effect on the electronic device 10. The material and preparation method of the sleeve body 21 are not limited. In some embodiments, the sleeving portion 214, the plate body portion 212, and the mounting portion 216 are of an integral structure. For example, the sleeving portion 214, the plate body portion 212, and the mounting portion 216 are integrally formed using the same plastic, glass, or any other suitable material. Or, the plate body portion 212 and the mounting portion 216 are integrally formed using the same plastic, glass, or any other suitable material, while the material of the sleeving portion 214 is a flexible plastic material and is prepared with the plate body portion 212 by a two-color injection molding process. This is not only beneficial to ensuring the structural strength of the plate body portion 212 and the mounting portion 216, improving the structural strength of the sleeve body 21 and the protective effect on each component of the protective cover 20, but also enables the sleeving of the sleeving portion 214 on the electronic device 10 to be easier.

[0053] In some embodiments, the plate body portion 212 and the mounting portion 216 can also be integrally formed using any suitable rigid materials such as metal, tempered glass, etc., to enhance the structural strength of the sleeve body 21 and the protection effect on each component of the protective case 20. The material of the sleeving portion 214 is any suitable soft rubber material. The sleeving portion 214 is sleeved at the four corners of the plate body portion 212, which is beneficial to the installation of the sleeve body 21 on the electronic device 10 and reduces the damage of the sleeve body 21 itself to the electronic device 10. Of course, the structure, material, and preparation method of the sleeve body 21 are not limited to the description of this application, as long as it can provide a protection effect on the electronic device 10 and can provide a limiting and protection effect on each component housed in the protective case 20. For example, in some embodiments, the materials of the plate body portion 212 and the mounting portion 216 can be one or a mixture of any suitable materials with sufficient strength such as polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), etc. The material of the sleeving portion 214 is any suitable material with elastic deformation ability such as thermoplastic polyurethane (TPU). The sleeving portion 214 and the plate body portion 212 are integrally formed by two-color injection molding or sleeved on the plate body portion 212. According to different strength requirements, the plate body portion 212 and the mounting portion 216 can also adopt other functions with higher strength such as Kevlar fiber to meet different scenario requirements.

[0054] In some embodiments, the protective case 20 further includes a main board 24, an ink screen 22, and a battery element 25 disposed in the installation space 218. The main board 24 includes, but is not limited to, a printed circuit board or a flexible circuit board integrating the control circuit and the power supply circuit of each component in the protective case 20. The ink screen 22 is electrically connected to the main board 24, and the display surface of the ink screen 22 faces away from the electronic device 10. That is to say, the display surface of the ink screen 22 is opposite to the display surface of the display screen of the electronic device 10. The battery element 25 includes, but is not limited to, any suitable rechargeable battery such as an ultra-thin lithium battery. The thickness of the battery element 25 can be less than or equal to 1 mm to compress the occupied space of the battery element 25, which is beneficial to reducing the volume of the protective case 20. The battery element 25 can store electrical energy. The battery element 25 is electrically connected to the main board 24 and is used to supply power to the ink screen 22 and other components of the protective case 20.

[0055] It can be understood that by providing the e-ink screen 22 on the protective cover 20, when the display screen of the electronic device 10 is turned off, the e-ink screen 22 can display image information for the user to view. Moreover, the burden on the user's eyes caused by viewing the e-ink screen 22 is much lower than that of the display screen of the electronic device 10, which is beneficial to reducing the damage to the user's health caused by the electronic device and making up for the deficiencies of the electronic device 10. At the same time, the power consumption of the e-ink screen 22 is also much lower than that of the display screen of the electronic device 10, which can reduce the power consumption of the electronic device and extend the usage time of the electronic device, enhancing the user experience. For example, when the user only needs to view the image information that the e-ink screen 22 can display, or when viewing the display screen of the electronic device 10 causes eye fatigue, or when the remaining power of the electronic device 10 is insufficient, the user can turn off the display screen of the electronic device 10 and view e-books, black-and-white images and videos, call information, text messages, etc. through the e-ink screen 22. The e-ink screen 22 can also display time information, the battery level of the protective cover 20, wireless communication status, recording status, etc. in the status bar. It should be noted that a battery element 25 is provided inside the protective cover 20 to supply power to the e-ink screen 22, which can provide a feasible basis for the e-ink screen 22 to adopt an active design, improving the operating power and performance stability of the e-ink screen 22, so that the e-ink screen 22 can display rich black-and-white images and video information, not limited to simple pictures or text information, effectively enriching the display function of the protective cover 20 and enabling the display function of the protective cover 20 to effectively supplement the electronic device 10. Of course, the display screen of the e-ink screen 22 is not limited to the description in this application. According to different instructions of the electronic device 10 or different program settings of the user, the e-ink screen 22 can also be used to display personalized wallpapers, to-do lists, or any other applicable black-and-white images and video screens. The content of the display screen of the e-ink screen 22 is not limited in this application.

[0056] In some embodiments, the protective cover 20 further includes a sound sensor 23 and a first button 26. The sound sensor 23 includes, but is not limited to, any applicable microphone element such as an MIC sensor. The sound sensor 23 is used to receive sound signals and convert them into electrical signals for transmission to the main board 24. The first button 26 is provided on the housing 21, and at least a part of the first button 26 is exposed outside the housing 21. The first button 26 can turn on the sound sensor 23 when pressed, for example, driving the main board 24 to transmit an instruction to start recording to the sound sensor 23.

[0057] It can be understood that when the electronic device 10 does not have a recording function, or in the scenario of continuous fast recording, and the recording operation of the electronic device 10 is not convenient enough, the user can press the first button 26 to drive the sound sensor 23 to start recording. The sound sensor 23 can convert the received sound signal into an electrical signal and store it in the protective cover 20, or transmit it to the electronic device 10 to make up for the lack of a recording function of the electronic device 10, or the inconvenience of the recording function operation, which is difficult to meet the needs of some scenarios. For example, the protective cover 20 may further include a storage chip provided on the main board 24, and the storage chip is used to store the electrical signal generated by the sound sensor 23. The protective cover 20 may further include a wireless communication module (not shown in the figure) provided on the main board 24. The wireless communication module includes, but is not limited to, a Bluetooth module. The wireless communication module is used to transmit the sound information stored in the storage chip, or the electrical signal formed by the sound sensor 23, to the electronic device 10.

[0058] The sound information received by the sound sensor 23 can be transmitted to the electronic device 10 through the wireless communication module, so that it can be played through the electronic device 10 when the user needs it, or converted into text information by the voice-to-text conversion software of the electronic device 10 and displayed on the display screen of the electronic device 10 or the e-ink screen 22 of the protective cover 20. Further, the sound information received by the sound sensor 23 can also be combined with the artificial intelligence algorithm configured in the electronic device 10 to realize the interaction between the user's voice and the artificial intelligence algorithm, enriching the use experience of the electronic device. For example, the APP end of the electronic device 10 can be used to play or convert the audio collected by the sound sensor 23 into text, or summarize and generalize the audio through the artificial intelligence port integrated in the APP end to form a summary or mind map, which is displayed on the display surface of the display screen of the electronic device 10 or the e-ink screen 22. Of course, the wireless communication module can also be used to realize the communication connection between other components such as the e-ink screen 22 and the electronic device 10, so as to control the display content of the e-ink screen 22 through the instructions of the electronic device 10, which is beneficial to enrich the display function of the e-ink screen 22 and improve the user experience.

[0059] The above-mentioned protective case 20 is provided with an e-ink screen 22. When the screen of the electronic device 10 is turned off, the e-ink screen 22 can be used for the user to view call information, browse images or read e-books. Moreover, reading on the e-ink screen 22 can reduce the burden on the user's eyes compared to the screen of the electronic device 10, and reduce the damage to the user caused by electronic products, thereby making up for the defects of the electronic device 10 and enriching the functions of the protective case 20. At the same time, a sound sensor 23 is also integrated in the protective case 20. When the electronic device 10 does not have a recording function, the protective case 20 can still receive sound signals through the sound sensor 23 and store them in the main board 24 or send them to the electronic device 10, making up for the functional defects of the electronic device 10. Furthermore, the user can turn on the recording function by pressing the first button 26. Compared with the recording function of the electronic device 10, the operation is more convenient, which can also improve the convenience of recording, make up for the defects of the electronic device 10, and adapt to different recording scenarios.

[0060] Combined with Figure 3 and Figure 4 As shown, in some embodiments, the main board 24 includes a first board portion 242 and a second board portion 244 that are connected to each other. The protective case 20 is provided with two sound sensors 23, and both of the two sound sensors 23 are disposed on the first board portion 242, and the two sound sensors 23 are respectively located at two corners of the first board portion 242 that are far away from each other. The connection line of the geometric centers of the two sound sensors 23 can be inclined to the extension direction of the first board portion 242. That is to say, the two sound sensors 23 are respectively disposed at the diagonals of the first board portion 242. By setting the two sound sensors 23 to cooperate, sound signals are received simultaneously at the two diagonals of the first board portion 242, and after being processed by the chip on the main board 24, they are synthesized into an audio segment, which can achieve a stereo reception effect, is beneficial to reducing noise interference, and improving the stability and quality of the received sound information.

[0061] In some embodiments, the first board portion 242 is provided with a first contact 2422, and the first button 26 is correspondingly arranged with respect to the first contact 2422. The first button 26 can contact the first contact 2422 when being pressed, so as to realize the on / off control function of the sound sensor 23. In some embodiments, the protective case 20 further includes a second button 27 disposed on the casing 21, and the first board portion 242 is further provided with a second contact. At least a part of the second button 27 is exposed outside the casing 21. The second button 27 can be used as the power-on button of the protective case 20. The second button 27 can contact the second contact 2424 when being pressed, so as to realize the on / off control of the protective case 20, for example, to realize the on / off control of the e-ink screen 22 and other components.

[0062] Further, in some embodiments, both the first contact 2422 and the second contact 2424 are located on the first plate portion 242. The line connecting the geometric centers of the first contact 2422 and the second contact 2424 is parallel to the extension direction of the first plate portion 242. The line connecting the geometric centers of the two sound sensors 23 intersects the line connecting the geometric centers of the first contact 2422 and the second contact 2424. Thus, the layout of the sound sensors 23, the first contact 2422, and the second contact 2424 on the first plate portion 242 can be reasonably configured, which is beneficial to adapting to the circuit design of the main board 24, and makes it difficult for the first button 26 and the second button 27 to interfere with the sound sensors 23 and other components, and also compresses the occupied space of the first plate portion 242.

[0063] There is no specific limitation on the specific settings of the first button 26 and the second button 27, as long as they can cooperate with the first contact 2422 and the second contact 2424 to respectively implement the on / off control functions of the sound sensor 23 and the ink screen 22. Figure 3 、 Figure 4 and Figure 5 As shown in FIGS. , in some embodiments, the protective cover 20 further includes a bridging element 28 and a reset element (not shown in the figure). The bridging element 28 is connected to the first button 26 and the second button 27, and is rotatably disposed on the first plate portion 242 through a support structure (not shown in the figure) disposed on the first plate portion 242. The reset element includes but is not limited to any suitable elastic element such as a spring. Two reset elements can be provided, and the two reset elements are respectively disposed between the first button 26 and the first plate portion 242, and between the second button 27 and the first plate portion 242. It can be understood that when the user presses the first button 26, it will drive the first button 26 to approach the first plate portion 242 until it contacts the first contact 2422, and at the same time drive the part of the bridging element 28 connected to the first button 26 to move closer to the first plate portion 242 relative to the support structure. During the process of pressing the first button 26, the first button 26 or the bridging element 28 and the first plate portion 242 jointly compress the reset element provided corresponding to the first button 26. After pressing the first button 26, the elastic restoring force of the reset element drives the first button 26 to leave the first plate portion 242, and the bridging element 28 is reset. By providing the bridging element 28 to connect the first button 26 and the second button 27, the first button 26 and the second button 27 can be mutually limited to improve the accuracy and stability of the button function, and can also improve the structural strength and reliability of the first button 26 and the second button 27.

[0064] As shown in FIGS. Figure 6 and Figure 7As shown, in some embodiments, the plate body portion 212 has a first zone portion 2122. The first zone portion 2122 protrudes from one side of the plate body portion 212 facing the installation space 218, and the first zone portion 2122 can be recessed from one side of the plate body portion 212 facing the electronic device 10. The plate body portion 212 is provided with a camera hole 2124 for facing the camera of the electronic device 10 and a flash hole 2126 for facing the flash of the electronic device 10. There may be three camera holes 2124 in the first zone portion 2122. The number and arrangement positions of the holes on the first zone portion 2122 can be adaptively adjusted according to different electronic devices 10, as long as the functions of the electronic device 10 are not affected when the protective cover 20 is sleeved on the electronic device 10.

[0065] Further, in some embodiments, the first plate portion 242 of the main board 24 is located on one side of the first zone portion 2122 in the first direction, and the second plate portion 244 is located on one side of the first zone portion 2122 in the second direction. The first plate portion 242 extends along the second direction. The first direction and the second direction are two mutually perpendicular directions on a plane parallel to the plate body portion 212. For example, the first direction may correspond to the width direction of the plate body portion 212 and the electronic device 10, and the second direction may correspond to the length direction of the plate body portion 212 and the electronic device 10.

[0066] In some embodiments, the battery element 25 is located on one side of the second plate portion 244 facing away from the first zone portion 2122 in the second direction, and the battery element 25 is electrically connected to the second plate portion 244 at a position away from the first plate portion 242 in the second direction. At least part of the battery element 25 and at least part of the second plate portion 244 are arranged on the same layer. Further still, in some embodiments, the two opposite side surfaces of the first plate portion 242 are respectively in limiting cooperation with the side surface of the first zone portion 2122 and the mounting portion 216, one side surface of the second plate portion 244 is in limiting cooperation with the side surface of the first zone portion 2122, and the other two opposite side surfaces of the second plate portion 244 are respectively in limiting cooperation with the two inner wall surfaces of the mounting portion 216 opposite to each other. With such an arrangement, the main board 24 and the battery are attached to the plate body portion 212 without interfering with each other, and do not interfere with the various openings on the first zone portion 2122. The components provided on the main board 24 also do not interfere with the first zone portion 2122 and the battery element 25, which can reasonably arrange the spatial layout of the main board 24, the battery element 25, and the various components provided on the main board 24, improve the performance stability of the protective cover 20, and at the same time is beneficial to reducing the thickness dimension of the protective cover 20.

[0067] In some embodiments, the first plate portion 242 and the second plate portion 244 may be a printed circuit board or a flexible circuit board with an integrated structure. In other embodiments, the second plate portion 244 may be a printed circuit board, and the first plate portion 242 may be a flexible circuit board connected to the second plate portion 244. Thus, the mounting reliability of each component on the second plate portion 244 can be improved, and the first plate portion 242 can also adapt to the relatively small mounting space 218 between the side surface of the first region portion 2122 and the mounting portion 216 in the first direction, enhancing the structural compactness of the protective cover 20, compressing the volume of the protective cover 20 while integrating more components to achieve richer functions.

[0068] Combined Figure 6 with Figure 8 as shown, in some embodiments, the protective cover 20 further includes a wireless charging component 29 received in the mounting space 218. The wireless charging component 29 may be composed of a coil element 292 and a magnetic component 294 such as a magnet. The coil element 292 of the wireless charging component 29 is electrically connected to the battery element 25 or electrically connected to the main board 24 to be electrically connected to the battery element 25 through the main board 24. The coil element 292 of the wireless charging component 29 is used to sense the coil of the electronic device 10 or the coil of a wireless charging device and can generate electric energy under the drive of the coil of the electronic device 10 or the coil of the wireless charging device to charge the battery element 25. Setting the wireless charging component 29 in the protective cover 20 to charge the battery element 25 facilitates the battery element 25 to supply power to each component such as the ink screen 22 in the protective cover 20, so that the protective cover 20 does not need to adopt a wired charging method, which is beneficial to improving the usability of the protective cover 20.

[0069] It can be understood that the electronic device 10 in the electronic device may be provided with a receiving coil, that is, the electronic device 10 has a wireless charging function. When the electronic device is placed on a wireless charging device, the receiving coil of the electronic device 10 cooperates with the transmitting coil of the wireless charging device, so that the wireless charging device can wirelessly charge the electronic device 10. A wireless charging component 29 is arranged in the protective case 20. When the electronic device is placed on a wireless charging device and the transmitting coil of the wireless charging device charges the electronic device 10, the wireless charging component 29 in the protective case 20 can also cooperate with the transmitting coil of the wireless charging device at the same time, so that the wireless charging device can charge the battery element 25 in the protective case 20 through the wireless charging component 29 at the same time. This is beneficial to improving the power utilization efficiency of the wireless charging device, and the cooperation between the battery element 25 and the battery in the electronic device 10 is also beneficial to increasing the power storage capacity of the electronic device and extending the usage time. When the electronic device is not placed on a wireless charging device, if the protective case 20 has insufficient power, the wireless charging component 29 cooperates with the receiving coil of the electronic device 10, and can also charge the battery element 25 of the protective case 20 through the receiving coil of the electronic device 10. That is to say, the protective case 20 can be charged by means of the reverse wireless charging function of the electronic device 10, and the usage time of the protective case 20 can be extended without relying on a wireless charging device, improving the usage convenience.

[0070] Therefore, when the protective case 20 is sleeved on the electronic device 10 to form an electronic device with the electronic device 10, the receiving coil of the electronic device 10 can be a bidirectional coil, and the electronic device 10 has a first state and a second state. In the first state, the electronic device is placed on a wireless charging device, and the bidirectional coil cooperates with the transmitting coil of the wireless charging device, so that the wireless charging device can charge the electronic device 10. In the second state, the bidirectional coil cooperates with the wireless charging component 29, and the reverse wireless charging function of the electronic device 10 for the protective case 20 can be realized, and the usage time of the protective case 20 can be extended by means of the power of the electronic device 10. Of course, in some other embodiments, the protective case 20 can also charge the battery element 25 by other any applicable means such as wired charging. For example, the housing 21 can be provided with a USB interface to be electrically connected to the electronic device 10 or an external power source through a data cable to charge the protective case 20. In some embodiments, when the protective case 20 is sleeved on the electronic device 10, the protective case 20 can also establish a communication connection with the electronic device 10 by replacing the wireless communication module with a data cable.

[0071] In some embodiments, the wireless charging assembly 29 includes a coil element 292 and a magnetic element 294. The coil element 292 can be generally in a ring-shaped sheet structure, and the magnetic element 294 can also be generally in a ring-shaped sheet structure. The magnetic element 294 is disposed around the periphery of the coil element 292, and at least part of the magnetic element 294 and the coil element 292 are disposed on the same layer. The wireless charging assembly 29 is stacked on the second plate portion 244 and the battery element 25. For example, two parts of the coil element 292 and two parts of the magnetic element 294 can be respectively opposite to the second plate portion 244 and the battery element 25. It can be understood that arranging the magnetic element 294 in the wireless charging assembly 29 is also beneficial for placing the electronic device on any applicable device such as a wireless charging device or a vehicle-mounted mobile phone holder in a magnetically fixed manner, so that neither the electronic device 10 nor the protective case 20 needs to be additionally configured with a fixing bracket or a magnet to achieve magnetic fixation, which is beneficial for simplifying the structure of the electronic device 10 and reducing the volume of the electronic device 10. The layout cooperation between the magnetic element 294 and the coil element 292 is also beneficial for reducing the occupied space of the magnetic element 294 in the protective case 20 and is beneficial for reducing the volume of the protective case 20. The form of the coil element 292 involved in the present application includes but is not limited to a flexible circuit board, a printed circuit board, a Litz coil, a single-layer spiral coil, etc.

[0072] Combined with Figure 3 As shown, in some embodiments, the ink screen 22 is stacked on the side of the wireless charging assembly 29 facing away from the battery element 25, and the wireless charging assembly 29 is clamped between the second plate portion 244, the battery element 25, and the ink screen 22. The ink screen 22 can be electrically connected to the second plate portion 244, and the connection position between the ink screen 22 and the second plate portion 244 can be located within the space defined by the inner ring edge of the coil element 292. Further, in some embodiments, the ink screen 22 is located on one side of the first region portion 2122 in the second direction, and the side surface of the ink screen 22 can be in limit cooperation with the side surface of the first region portion 2122. With such an arrangement, the layout of the components in the installation space 218 can be reasonably configured, the structural compactness of the protective case 20 can be improved, which is beneficial for reducing the thickness dimension of the protective case 20. At the same time, the wiring of each component can be reasonably planned to avoid interference between the components, which is beneficial for improving the performance stability of the protective case 20.

[0073] In some embodiments, the sleeve 21 further includes four limiting ribs 219, which are arranged in pairs on two inner wall surfaces opposite to the mounting portion 216, and the two limiting ribs 219 located on the same inner wall surface are arranged at intervals from each other, and one of the two limiting ribs 219 located on the same inner wall surface is limitedly matched with the second plate portion 244, and the other is limitedly matched with the battery element 25. The two limiting ribs 219 located on the same inner wall surface are spaced from each other to avoid the wireless charging component 29, and the wireless charging component 29 is limitedly matched with the two inner wall surfaces opposite to the mounting portion 216 between the limiting ribs 219. Such a configuration is conducive to improving the installation stability of each component in the installation space 218, thereby helping to improve the structural reliability and performance stability of the protective cover 20.

[0074] Please see again Figure 1 and Figure 3 In some embodiments, the protective cover 20 further includes a touch cover plate 31, which is disposed on the cover body 21 and is provided with a first through hole 312 corresponding to the camera hole 2124 and a second through hole 314 corresponding to the first button 26. The touch cover plate 31 is also provided with other through holes corresponding to the flash hole 2126 and the second button 27. The first button 26 and the second button 27 are exposed from the touch cover plate 31 for the user to press. The touch cover plate 31 is at least partially opposite to the display surface of the ink screen 22, the touch cover plate 31 is electrically connected to the main board 24, and the touch sensing area of ​​the touch cover plate 31 at least covers the display surface area of ​​the ink screen 22. The touch cover plate 31 can be fully fitted with the ink screen 22. The touch cover plate 31 is provided on the protective cover 20, so that the user can realize touch operation. The provision of the ink screen 22 can improve the convenience of use and operation of the protective cover 20. For example, the user can answer calls, flip pages left and right, slide pages up and down, zoom in and out pages, etc. by touching the touch cover 31 and coordinating the screen changes of the ink screen 22, thereby enriching the functions of the protective cover 20.

[0075] The realization of the touch function is also conducive to the user to interact with the APP or artificial intelligence algorithm of the electronic device 10 through the touch function of the protective cover 20, thereby enriching the functions and operations of the protective cover 20 to the greatest extent when the display screen of the electronic device 10 is off, improving the high degree of integration of the functions of the protective cover 20 and the electronic device 10, and improving the user experience. For example, when the protective cover 20 establishes a communication connection with the electronic device 10 through the wireless communication module, the touch cover 31 and the ink screen 22 can be connected to the app of the electronic device 10, and the operation and interaction of the app of the electronic device 10 can be realized by operating the touch cover 31. While realizing richer functions, it is conducive to simplifying the design difficulty and design cost of the processor and circuit of the mainboard 24 of the protective cover 20 itself, and reducing the preparation cost of the protective cover 20.

[0076] Further, in some embodiments, the touch control cover plate 31 is covered on the installation part 216 and seals the installation space 218. The touch control cover plate 31 and the installation part 216 can be fixed to each other by any applicable means such as gluing. That is to say, the touch control cover plate 31 covers the first plate part 242, the ink screen 22, and the first area part 2122, and serves as the outermost structural member on the side of the protective cover 20 facing away from the electronic device 10. In this way, while the touch control cover plate 31 is provided to achieve the touch control function, the touch control cover plate 31 can cooperate with the installation part 216 to jointly serve as the outer shell member of the protective cover 20, which is beneficial to saving the consumables of the sleeve body 21 and reducing the manufacturing cost of the protective cover 20. It can be understood that the touch control area of the touch control cover plate 31 at least covers the display surface area of the ink screen 22, so as to cooperate with the display screen of the display to achieve accurate, efficient, and rich touch control functions.

[0077] The touch control cover plate 31 may include two glass cover plates arranged in a stacked manner and a touch control electrode layer arranged between the two glass cover plates in a stacked manner. This is beneficial to protecting the touch control electrode layer and also beneficial to improving the structural strength of the touch control cover plate 31, so that the touch control cover plate 31 has sufficient structural strength to serve as the outer shell member of the protective cover 20 and provide a protective effect on the various components in the installation space 218. It can be understood that a light-shielding layer such as ink may be provided on the part of the inner glass cover plate of the touch control cover plate 31 corresponding to the outside of the touch control area to shield the touch control circuit and the various components in the installation space 218, and improve the appearance integrity of the protective cover 20.

[0078] In some embodiments, the part of the touch control cover plate 31 opposite to the first area part 2122 is fixed to the first area part 2122 by any applicable means such as gluing, which is beneficial to improving the installation firmness of the touch control cover plate 31 on the sleeve body 21 by means of the structural setting of the first area part 2122 and improving the structural reliability of the protective cover 20.

[0079] In some embodiments, the protective cover 20 may also be integrated with any applicable components such as decorative lights, lighting sources, sound players, etc. to achieve more abundant functions. The above-mentioned components may also be replaced by any other applicable components to achieve the corresponding functions, which are not limited in this application.

[0080] Reference Figure 9 , Figure 9Schematic diagram of the structure of the electronic device 10 provided by the embodiments of the present application. The electronic device 10 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, sensors 505, an audio circuit 506, a wireless fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509, etc. Those skilled in the art can understand that Figure 9 the structure of the electronic device 10 shown in

[0081] does not limit the electronic device 10, and may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. The RF circuit 501 can be used to receive and transmit information, or receive and send signals during a call. In particular, after receiving the downlink information of the base station, it is handed over to one or more processors 508 for processing; in addition, the data related to the uplink is sent to the base station. Usually, the RF circuit 501 includes, but is not limited to, antennas, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the RF circuit 501 can also communicate with the network and other devices through wireless communication. This wireless communication can use any communication standard or protocol, including but not limited to the global system of mobile communication (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), long term evolution (LTE), email, short messaging service (SMS), etc.

[0082] The memory 502 can be used to store application programs and data. The application programs stored in the memory 502 contain executable codes. The application programs can form various functional modules. The processor 508 executes various functional applications and data processing by running the application programs stored in the memory 502. The memory 502 may mainly include a program storage area and a data storage area. Among them, the program storage area can store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.); the data storage area can store data created according to the use of the electronic device 10 (such as audio data, a phone book, etc.). In addition, the memory 502 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one magnetic disk storage device, a flash memory device, or other volatile solid-state storage devices. Correspondingly, the memory 502 may further include a memory controller to provide access to the memory 502 by the processor 508 and the input unit 503.

[0083] The input unit 503 can be used to receive input digital, character information or user characteristic information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function controls. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touchpad, can collect touch operations of the user on or near it (such as operations of the user using a finger, a stylus, or any suitable object or accessory on or near the touch-sensitive surface), and drive the corresponding connection device according to a preset program. Optionally, the touch-sensitive surface may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the touch position of the user and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 508, and can receive and execute the commands sent by the processor 508.

[0084] The display unit 504 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the electronic device 10. These graphical user interfaces can be composed of graphics, text, icons, videos, and any combination thereof. The display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, a touch-sensitive surface can cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event. Subsequently, the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in Figure 9 the touch-sensitive surface and the display panel are implemented as two independent components to achieve input and input functions, in some embodiments, the touch-sensitive surface and the display panel can be integrated to achieve input and output functions. It can be understood that the display screen 110 may include an input unit 503 and a display unit 504.

[0085] The electronic device 10 may further include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. Among them, the ambient light sensor can adjust the brightness of the display panel according to the brightness of the ambient light, and the proximity sensor can turn off the display panel and / or the backlight when the electronic device 10 is moved to the ear. As a kind of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in all directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used in applications for identifying the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. As for other sensors such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors that the electronic device 10 can also be configured with, they will not be elaborated here.

[0086] The audio circuit 506 can provide an audio interface between the user and the electronic device 10 through a speaker and a microphone. The audio circuit 506 can convert the received audio data into an electrical signal and transmit it to the speaker, which converts it into a sound signal for output. On the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and then converted into audio data. After the audio data is output and processed by the processor 508, it is sent through the radio frequency circuit 501 to, for example, another electronic device 10, or the audio data is output to the memory 502 for further processing. The audio circuit 506 may also include a headphone jack to provide communication between the peripheral headphones and the electronic device 10.

[0087] Wireless Fidelity (WiFi) belongs to short - range wireless transmission technology. The electronic device 10 can help users send and receive emails, browse the web, and access streaming media, etc. through the WiFi module 507, which provides users with wireless broadband Internet access. Although Figure 9 the WiFi module 507 is shown, it can be understood that it does not belong to the essential components of the electronic device 10 and can be omitted entirely within the scope of not changing the essence of the utility model as needed.

[0088] The processor 508 is the control center of the electronic device 10, connecting various parts of the entire electronic device 10 through various interfaces and circuits. By running or executing application programs stored in the memory 502 and calling data stored in the memory 502, it executes various functions of the electronic device 10 and processes data, thereby monitoring the electronic device 10 as a whole. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor. Among them, the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communication. It can be understood that the above - mentioned modem processor may not be integrated into the processor 508 either.

[0089] The electronic device 10 further includes a power supply 509 for powering each component. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, thereby realizing functions such as management of charging, discharging, and power consumption management through the power management system. The power supply 509 may also include any components such as one or more DC or AC power supplies, a recharge system, a power failure detection circuit, a power converter or inverter, a power status indicator, etc.

[0090] Although Figure 9 not shown in the figure, the electronic device 10 may also include a Bluetooth module, etc., which will not be elaborated here. In specific implementation, each of the above - mentioned modules can be implemented as an independent entity, or can be combined arbitrarily and implemented as the same or several entities. For the specific implementation of each of the above - mentioned modules, reference can be made to the previous method embodiments, which will not be elaborated here.

[0091] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above - mentioned embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0092] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application.
