[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] The following is combined with Figures 1-10 The present invention will provide a detailed description of the charging protective cover, charger and electronic device provided by the embodiments of the present invention through specific implementation methods and application scenarios.

[0034] In the first aspect, such as Figures 1 to 4 As shown, this utility model embodiment provides a charging protective case, including: a protective case body 1, a first charging port 2, a second charging port 3, and a support member 4; The protective case body 1 has a storage section 11 on the front side for storing the tablet device 100; a first charging port 2 and a second charging port 3 are electrically connected and respectively disposed on the protective case body 1. The first charging port 2 is configured to be electrically connected to the tablet device 100, and the second charging port 3 is configured to be electrically connected to the charger 5; the support member 4 is movably disposed on the protective case body 1 and has a first state and a second state relative to the protective case body 1. In the case where the support member 4 is in the first state, the support member 4 is stored on the back of the protective cover body 1 so that the charging protective cover and the charger 5 can be connected. When the support member 4 is in the second state, the protective sleeve body 1 is placed at an angle on the horizontal platform under the support of the support member 4 to support the flat plate equipment 100.

[0035] It is understood that the protective case body 1 can be a plastic protective case or a leather protective case, and there is no specific limitation on this.

[0036] Regarding the storage portion 11 on the protective case body 1, the storage portion 11 can be a clamping structure that can be clamped to both sides of the tablet device 100, or it can be a suction structure that can be attracted to the back of the tablet device 100, such as an elastic suction cup or a magnetic attachment. The tablet device 100 can be a learning machine or a tablet computer.

[0037] The first charging port 2 is electrically connected to the second charging port 3 via a power line built into the protective case body 1. The first charging port 2 can be located on the front or side of the protective case body 1; there is no specific limitation in this location. When the tablet device 100 is stored in the storage section 11, it is only necessary to facilitate the electrical connection between the first charging port 2 and the third charging port of the tablet device 100. The second charging port 3 can be located on the back or side of the protective case body 1; there is no specific limitation in this location. When the charger 5 and the charging protective case are connected, it is only necessary to facilitate the electrical connection between the second charging port 3 and the fourth charging port of the charger 5.

[0038] To facilitate electrical connection between the first charging port 2 and the third charging port, and to facilitate electrical connection between the second charging port 3 and the fourth charging port, at least one of the first charging port 2 and the second charging port 3 is a Pogopin interface. For example, the first charging port 2 and the third charging port are compatible Pogopin interfaces, and the second charging port 3 and the fourth charging port are compatible Pogopin interfaces.

[0039] Of course, one of the first charging port 2 and the second charging port 3 can be set to a Type-C interface, and the other of the first charging port 2 and the second charging port 3 can be a Pogopin interface. There are no specific restrictions on this.

[0040] For the support member 4, one end of the support member 4 can be connected to the back or side of the protective sleeve body 1 via a flexible connection or hinge, so that the support member 4 can be movably set on the protective sleeve body 1, for example, the support member 4 and the back of the protective sleeve body 1 can be movably connected.

[0041] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, when the support member 4 is in the first state, the support member 4 is connected to the back of the protective cover body 1, for example, the support member 4 and the back of the protective cover body 1 are magnetically attracted to each other, so that the support member 4 can be stored in the back of the protective cover body 1. At this time, the entire charging protective cover is in a folded state, which makes it easy to connect the charging protective cover and the charger 5, and the charger 5 charges the tablet device 100 set on the charging protective cover.

[0042] like Figure 3 , Figure 4 and Figure 5As shown, when the support member 4 is in the second state, the support member 4 supports the back of the protective case body 1. The protective case body 1 is tilted on the horizontal platform under the support of the support member 4. At this time, the entire charging protective case is in the unfolded state. The vertically distributed tablet device 100 can be reliably stored in the storage part 11 of the protective case body 1. For example, the display surface of the tablet device 100 is tilted relative to the horizontal platform, which facilitates the implementation of the finger reading function based on the flip-out camera module 1002 of the tablet device 100.

[0043] In practical applications, the support member 4 can be a foldable member that can switch forms. Based on the supporting role of the support member 4, the protective cover body 1 can be kept at different tilt angles relative to the horizontal platform, so that users can adjust the placement posture of the tablet device 100 relative to the horizontal platform according to actual needs through the charging protective cover.

[0044] like Figure 8 and Figure 9 As shown, when the entire charging protective case is in a folded state, considering that the tablet device 100 is tilted relative to the horizontal platform when the charger 5 charges the tablet device 100 set on the charging protective case, the finger reading function can be realized based on the flip-up camera module 1002 on the tablet device 100.

[0045] For example, such as Figure 8 As shown, the tablet device 100 includes a device body 1001 and a camera module 1002. The device body 1001 is housed in a storage section 11 located on the front of the protective case body 1. The display surface of the device body 1001 is disposed away from the protective case body 1. The camera module 1002 is disposed on the back of the device body 1001. The camera module 1002 can be flipped from the back of the device body 1001 toward the front of the display surface to identify a target object (such as a paper medium) placed on the horizontal platform surface in front of the display surface.

[0046] The charging protective case shown in this utility model, by setting a first charging port 2, a second charging port 3, and a support member 4 based on the protective case body 1, can not only store the tablet device 100 using the storage part 11 of the protective case body 1 and provide physical protection for the tablet device 100 based on the protective case body 1, but also connect the charging protective case and the charger 5 when storing the tablet device 100. Without the need for additional wiring, the charger 5 can conveniently charge the tablet device 100 based on the charging link formed by the first charging port 2 and the second charging port 3 on the protective case body 1. Furthermore, when the support member 4 is set to a second state relative to the protective case body 1, it ensures that the protective case body 1 is placed stably on a horizontal platform in an inclined posture under the support of the support member 4, so as to support the three-dimensionally distributed tablet device 100 and facilitate the user's use of the tablet device 100's finger reading function. This design can conveniently provide the tablet device 100 with functions that take into account physical protection, charging, and finger reading assistance, thus improving the user experience.

[0047] In some embodiments, such as Figure 1 and Figure 3 As shown, the protective case body 1 has a storage groove on the front, which is formed as a storage part 11. The bottom of the storage groove is configured to fit against the back of the tablet device 100. The first charging port 2 is located at the bottom of the storage groove and is configured to be electrically connected to the third charging port located on the back of the tablet device 100.

[0048] It is understood that the front of the protective cover body 1 is provided with a rim, which extends circumferentially along the protective cover body 1 to form a storage slot for accommodating the tablet device 100 on the front of the protective cover body 1; wherein, the rim is provided with multiple openings, which are respectively arranged opposite to multiple functional devices on the side of the tablet device 100.

[0049] At the same time, by setting the first charging port 2 at the bottom of the storage slot, while storing the tablet device 100 in the storage slot, it is possible to ensure that the third charging port on the back of the tablet device 100 and the first charging port 2 on the protective case body 1 maintain a stable electrical connection, which is beneficial for the charger 5 to charge the tablet device 100 stably and reliably.

[0050] In practical applications, the first charging port 2 and the third charging port are preferably compatible Pogopin interfaces. This makes it easy to directly connect the first charging port 2 and the third charging port when the tablet device 100 is stored in the storage slot, and to easily separate the first charging port 2 and the third charging port when the user takes the tablet device 100 out of the storage slot.

[0051] In some examples, a first magnetic attraction component can be provided between the protective case body 1 and the tablet device 100 to ensure that the tablet device 100 is stably housed in the storage slot based on the magnetic attraction effect of the first magnetic attraction component. The first magnetic attraction component includes a first magnetic member and a second magnetic member disposed opposite to each other. The first magnetic member is disposed on the back of the tablet device 100, and the second magnetic member is disposed on the bottom of the storage slot.

[0052] In some examples, such as Figure 1 , Figure 6 and Figure 8 As shown, the protective case body 1 also has a receiving groove 12 on the front side. The receiving groove 12 is located on one side of the storage groove. The receiving groove 12 is used to receive the stylus 200. The user can hold the stylus 200 and input relevant control commands on the display surface of the tablet device 100.

[0053] In some embodiments, such as Figure 2 and Figure 5 As shown, the second charging port 3 is located on the back of the protective case body 1 and is configured to be electrically connected to the charger 5 supported on the back of the protective case body 1.

[0054] Understandably, the back of the protective case body 1 is configured to connect to the charger 5 so that the charger 5 is supported on the back of the protective case body 1, ensuring the stability of the tablet device 100 when it is being charged.

[0055] Meanwhile, the area where the charger 5 connects to the protective case body 1 can be located around the second charging port 3. This design ensures a stable electrical connection between the second charging port 3 and the fourth charging port of the charger 5 while maintaining a mechanical connection between the back of the protective case body 1 and the charger 5.

[0056] In some embodiments, such as Figure 5 , Figure 9 and Figure 10 As shown, in order to ensure the reliability of the mechanical connection between the back of the protective case body 1 and the charger 5, a positioning part 101 is provided on the back of the protective case body 1. The positioning part 101 is configured to be positioned and connected to the charging part 522 of the charger 5.

[0057] For example, such as Figure 5 , Figure 9 and Figure 10 As shown, the positioning part 101 is a positioning groove, and the charging part 522 has a protrusion adapted to the positioning groove. The positioning groove is used to accommodate the protrusion and magnetically engages with the protrusion. The second charging port 3 is disposed at the bottom of the positioning groove and is electrically connected to the fourth charging port located in the charging part 522.

[0058] It is understandable that the positioning and magnetic engagement between the positioning groove and the protrusion facilitates the detachable connection between the back of the protective case body 1 and the charging part 522 of the charger 5.

[0059] like Figure 10 As shown, the fourth charging port is located on the end face of the charging part 522 facing the protective cover body 1. When the back of the protective cover body 1 is connected to the charging part 522 of the charger 5, the end face of the charging part 522 facing the protective cover body 1 is in contact with the bottom of the positioning groove, and the second charging port 3 is electrically connected to the fourth charging port of the charging part 522.

[0060] like Figure 5 , Figure 7 and Figure 9 As shown, the charging unit 522 is usually configured to be tilted. Based on the cooperation between the charging unit 522 and the positioning groove, the protective cover body 1 is tilted relative to the horizontal platform surface, so as to support the tablet device 100 which is tilted, and facilitate the camera module 1002 of the tablet device 100 to realize the finger reading function.

[0061] In practical applications, when the back of the protective case body 1 is connected to the charging part 522 of the charger 5, at least part of the protrusion is inserted into the positioning groove. When the tablet device 100 is placed in the protective case body 1, the insertion and cooperation between the positioning groove and the protrusion can bear the downward gravity (gravitational component) from the tablet device 100, ensuring that the connection state between the protective case body 1 and the charger 5 does not change.

[0062] At the same time, the magnetic attraction between the positioning groove and the protrusion can further ensure the reliability of the connection between the back of the protective case body 1 and the charging part 522 of the charger 5.

[0063] For example, a second magnetic attraction component can be provided between the positioning groove and the protrusion. The second magnetic attraction component includes a third magnetic attraction member and a fourth magnetic attraction member disposed opposite to each other. The third magnetic attraction member is disposed at the bottom of the positioning groove, and the fourth magnetic attraction member is disposed on the side of the protrusion facing the protective sleeve body 1.

[0064] Multiple sets of the second magnetic attraction components can be provided. During the installation of the charging unit 522 toward the positioning slot, the magnetic force of the multiple sets of second magnetic attraction components can be used to magnetically position the charging unit 522.

[0065] In some embodiments, such as Figures 2 to 4As shown, the support member 4 includes a support plate, one end of which is rotatably connected to the back of the protective sleeve body 1; when the support plate is in the first state, the support plate and the back of the protective sleeve body 1 are in contact; when the support plate is in the second state, the support plate and the back of the protective sleeve body 1 are set at an angle.

[0066] It is understandable that one end of the support plate can be connected to the back of the protective sleeve body 1 via a hinge, so as to achieve a rotatable connection between one end of the support plate and the back of the protective sleeve body 1.

[0067] like Figure 2 As shown, when the support plate is in the first state, along the thickness direction of the protective sleeve body 1, the projection of the support plate is located in the area where the projection of the back of the protective sleeve body 1 is located, and the bottom edge of the support plate is aligned with the bottom edge of the protective sleeve body 1; wherein, the length of the support plate is approximately the same as the length of the protective sleeve body 1, and the width of the support plate is less than the width of the protective sleeve body 1.

[0068] like Figure 3 and Figure 4 As shown, when the support plate is in the second state, the included angle between the support plate and the back of the protective sleeve body 1 can be 30° to 150°; wherein, the smaller the included angle between the support plate and the back of the protective sleeve body 1, the larger the tilt angle of the protective sleeve body 1 and the flat plate equipment 100 contained therein relative to the horizontal platform surface, and the larger the included angle between the support plate and the back of the protective sleeve body 1, the smaller the tilt angle of the protective sleeve body 1 and the flat plate equipment 100 contained therein relative to the horizontal platform surface.

[0069] In some embodiments, to facilitate the storage of the support plate, the support plate is configured to magnetically engage with the back of the protective sleeve body 1.

[0070] It is understood that a third magnetic attraction assembly is provided between the support plate and the back of the protective sleeve body 1. The third magnetic attraction assembly includes a fifth magnetic attraction member and a sixth magnetic attraction member arranged opposite to each other. The fifth magnetic attraction member is provided on the support plate, and the sixth magnetic attraction member is provided on the back of the protective sleeve body 1.

[0071] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the support plate is provided with a clearance opening 41. When the support plate is in the first state, the second charging port 3 is located in the area defined by the clearance opening 41.

[0072] It is understandable that when the support plate is in the first state, although the support plate and the back of the protective case body 1 are in contact, the second charging port 3 can be exposed on the back of the protective case body 1 due to the setting of the clearance opening 41.

[0073] like Figure 6 and Figure 7 As shown, based on the design of the above-mentioned clearance opening 41, when the entire charging protective case is in a folded state, it is convenient for the charger 5 to charge the tablet device 100 stored on the protective case body 1 through the second charging port 3.

[0074] In some embodiments, such as Figures 1 to 4 ,as well as Figure 8 and Figure 9 As shown, the top edge of the protective case body 1 is provided with a notch 111, which is used to accommodate the flip-up camera module 1002 located on the back of the tablet device 100.

[0075] It is understood that in the case where the tablet device 100 includes a device body 1001 and a camera module 1002, a boss is provided on the back of the device body 1001. The boss is located near the top edge of the device body 1001 and is adapted to the notch 111. The flip-up camera module 1002 is provided on the boss.

[0076] When the tablet device 100 performs the finger reading function, the camera module 1002 flips from the back of the tablet device 100 to the front of the tablet device 100 to identify the target object (e.g., paper medium) placed on the horizontal platform surface at the front of the tablet device 100.

[0077] In the second aspect, such as Figures 6 to 10 As shown, this embodiment of the utility model also provides a charger 5, which is used to support the charging protective cover as described above, and is electrically connected to the second charging port 3 on the charging protective cover.

[0078] It is understandable that a support structure can be provided on the charger 5. While supporting the charging protective case based on the support structure, the charger 5 can also be electrically connected to the second charging port 3 on the charging protective case, so as to charge the tablet device 100 set on the charging protective case.

[0079] In the case where the charger 5 supports the charging protective cover, it can be ensured that the tablet device 100 set on the charging protective cover is tilted relative to the horizontal platform so that the user can use the finger reading function of the tablet device 100.

[0080] In some embodiments, such as Figure 7 and Figure 9 As shown, the charger 5 includes a charging support 51 and a charging arm 52; the charging support 51 is configured to be disposed on a horizontal platform, and the charging arm 52 is rotatably disposed on the charging support 51. The charging arm 52 is used to support the protective cover body 1 and is electrically connected to the second charging port 3.

[0081] It is understood that the charging support 51 includes a base and a support arm. The base is used to place on a horizontal platform. The bottom end of the support arm is connected to the base. The first end of the charging arm 52 is rotatably connected to the support arm by a hinge mechanism. The second end of the charging arm 52 is connected to the protective sleeve body 1.

[0082] By setting the charging arm 52 rotatably on the charging support 51, when the charging arm 52 and the protective sleeve body 1 are connected, the tilt angle of the protective sleeve body 1 and the tablet device 100 stored therein relative to the horizontal platform can be adaptively set according to actual needs, so as to meet the needs of the tablet device 100 for its tilted layout posture in the reading state.

[0083] In some embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, the charging arm 52 includes: a connecting arm 521, a charging part 522, and a bracket 523; The first end of the connecting arm 521 is rotatably connected to the charging support 51. The charging part 522 is disposed at the second end of the connecting arm 521. The charging part 522 is connected to the back of the protective cover body 1 and is electrically connected to the second charging port 3 located on the back of the protective cover body 1. The bracket 523 is connected to the charging part 522 and is used to support the bottom edge of the protective cover body 1.

[0084] The charging unit 522 has a fourth charging port on the end face facing the protective cover body 1. The fourth charging port is electrically connected to the second charging port 3. The second charging port 3 and the fourth charging port are preferably compatible Pogopin interfaces.

[0085] In some embodiments, the charger further includes a triggering component, which includes a permanent magnet and a Hall sensor. The permanent magnet is disposed on the protective cover body 1, and the Hall sensor is disposed on the charger 5 and electrically connected to the charger 5. With the charger 5 and the protective case body 1 connected, the permanent magnet and the Hall sensor are positioned opposite each other, and the charger 5 is configured to charge the tablet device 100 when triggered by the sensing signal of the Hall sensor.

[0086] It is understandable that the charger 5 contains a charging circuit board, which integrates a processor and a charging switch circuit. The Hall sensor is electrically connected to the processor, and the processor is electrically connected to the charging switch circuit. The charging switch circuit is used to control the connection status between the fourth charging port on the charger 5 and the external power source.

[0087] When the tablet device 100 is placed on the protective case body 1 and the charging arm 52 is connected to the protective case body 1, the permanent magnet and the Hall sensor are positioned opposite each other. The Hall sensor will generate a trigger signal under the action of the magnetic field of the permanent magnet. The processor controls the charging switch circuit to be turned on according to the trigger signal of the Hall sensor, so that the external power supply can be connected to the fourth charging port through the charging switch circuit, so that the charger 5 can charge the tablet device 100.

[0088] Correspondingly, when the charging arm 52 and the protective cover body 1 are separated, since the permanent magnet and the Hall sensor are far apart, the Hall sensor will not generate a trigger signal under the magnetic field of the permanent magnet. At this time, the processor controls the charging switch circuit to disconnect, and the charger 5 will no longer output power.

[0089] In the third aspect, such as Figures 1 to 5 As shown, this utility model embodiment also provides an electronic device, including a tablet device 100 and a charging protective case as described above; the tablet device 100 is housed in the storage part 11 of the protective case body 1.

[0090] It is understood that the tablet device can be a learning machine, tablet computer, or other device known in the art. When the support member 4 is in the first state, the entire charging protective case is in a folded state, and the tablet device 100 can be stored in the charging protective case and placed together on a horizontal platform or put into a bag. When the support member 4 is in the second state, the entire charging protective case is in an unfolded state, and the tablet device 100, which is vertically distributed, can be reliably stored in the storage part 11 of the protective case body 1, so that the tablet device 100 is vertically distributed on the horizontal platform for the user to use.

[0091] Since the electronic device includes a charging protective case, and the specific structure of the charging protective case refers to the above embodiments, the electronic device of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be described in detail here.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
