DETAILED DESCRIPTION

[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] Furthermore, the terms “first”, “second”, etc. used in the present disclosure are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0032] Figure 1 A schematic diagram of the structure of a protective cover in an embodiment of the present disclosure is shown. Figure 1 As shown, the protective cover includes: a first cover plate 100 , a second cover plate 200 , a magnetic trigger module and a control module 400 .

[0033] In some embodiments, a fixing groove 101 is provided on the first cover plate 100, and the fixing groove 101 is used to fix the electronic device. The electronic device can be any electronic device that can be operated by a keyboard and is suitable for the protective cover, such as a smart phone, a tablet computer, a learning machine, etc.

[0034] For example, the fixing groove 101 can be provided on at least two sides of the first cover plate 100, or on four corners of the first cover plate 100, which is not limited in the present embodiment. The edge of the electronic device can be snapped into the fixing groove 101 to fix the electronic device to the first cover plate 100.

[0035] In some embodiments, the second cover plate 200 is foldably connected to the first cover plate 100 , and a keyboard assembly 201 is fixed thereon.

[0036] Exemplarily, the second cover plate 200 and the first cover plate 100 may be connected by a flexible material, and the flexible material may be a material that can be bent arbitrarily, such as silicone, flexible plastic, cloth, leather, etc. When the second cover plate 200 and the first cover plate 100 are fully unfolded, the angle between the second cover plate 200 and the first cover plate 100 may be 180°, and the electronic device and the keyboard assembly 201 are located on the same surface of the first cover plate 100 and the second cover plate 200. When the second cover plate 200 and the first cover plate 100 are fully folded, the angle between the second cover plate 200 and the first cover plate 100 may be 0°, that is, the second cover plate 200 is parallel to the first cover plate 100.

[0037] In some embodiments, the magnetic trigger module includes a Hall sensor 301 and a magnet 302. The magnet 302 and the Hall sensor 301 can be respectively disposed in two different cover plates of the protective cover.

[0038] For example, if the Hall sensor 301 is disposed inside the first cover plate 100 , the magnet 302 may be disposed inside the second cover plate 200 . Accordingly, if the Hall sensor 301 is disposed inside the second cover plate 200 , the magnet 302 may be disposed inside the first cover plate 100 .

[0039] For example, when the second cover plate 200 and the first cover plate 100 are completely folded, the Hall sensor 301 can detect the magnetic field of the magnet 302, and the magnetic field strength of the magnetic field can reach the triggering threshold of the Hall sensor 301. In other words, when the first cover plate 100 and the second cover plate 200 are parallel to each other, the magnet 302 can trigger the Hall sensor 301.

[0040] In some embodiments, the control module 400 can be disposed inside the first cover plate 100 or the second cover plate 200 and electrically connected to the keyboard assembly 201 and the Hall sensor 301 respectively, for controlling the opening and closing of the keyboard assembly 201 according to the triggering state of the Hall sensor 301.

[0041] Based on this, when the Hall sensor 301 is in a triggered state, it can be determined that the first cover plate 100 and the second cover plate 200 have been folded to a state parallel to each other, and the keyboard assembly 201 is already at an invisible angle for the user, and the user cannot normally operate the keyboard assembly 201 in this state. At this time, the keyboard assembly 201 can be controlled to be closed by the control module 400 to avoid accidental touches of the keyboard. When the Hall sensor 301 is in an untriggered state, it can be determined that there is still a large angle between the first cover plate 100 and the second cover plate 200. At this time, the user can normally input information to the electronic device through the keyboard assembly 201, so the keyboard assembly 201 can be controlled to be opened by the control module 400 for the user to use.

[0042] In some embodiments, the protective cover has a positive buckle state and a reverse buckle state. When the protective cover is in the positive buckle state, the first cover plate 100 and the second cover plate 200 are parallel to each other, and the keyboard assembly 201 is located on a side of the second cover plate 200 close to the first cover plate 100. When the protective cover is in the reverse buckle state, the first cover plate 100 and the second cover plate 200 are parallel to each other, and the keyboard assembly 201 is located on a side of the second cover plate 200 away from the first cover plate 100.

[0043] The forward buckle state can be understood as the storage state of the electronic device with the protective cover installed, at which time the keyboard and the electronic device are located between the first cover plate 100 and the second cover plate 200, and the first cover plate 100 and the second cover plate 200 can protect both the keyboard and the electronic device. In the reverse buckle state, the user can focus on operating the electronic device without using the keyboard assembly 201, and it is convenient for the user to hold and place the electronic device with the protective cover installed.

[0044] It is worth noting that in the embodiment of the present disclosure, since the first cover plate 100 and the second cover plate 200 are parallel to each other in both the forward buckle state and the reverse buckle state, the Hall sensor 301 will be triggered by the magnet 302. Therefore, the control module 400 can control the keyboard assembly 201 to close to avoid accidental touches.

[0045] It is understandable that, regardless of whether the protective cover is in the forward buckled state or the reverse buckled state, the keyboard assembly 201 is invisible to the user. For example, in the forward buckled state, the electronic device and the keyboard assembly 201 will block each other between the first cover plate 100 and the second cover plate 200. At this time, the electronic device and the keyboard assembly 201 are invisible to the user, and it can be assumed that the user will not perform any operation on the electronic device or the keyboard assembly 201. In the reverse buckled state, if the user normally browses the electronic device fixed to the first cover plate 100, the keyboard assembly 201 is just on the back side of the electronic device, and the keyboard assembly 201 is still invisible to the user. In other words, regardless of whether the protective cover is in the forward buckled state or the reverse buckled state, the user has no need to use the keyboard assembly 201.

[0046] In some embodiments, at least one protrusion 202 is further provided around the keyboard assembly 201, and the height of the protrusion 202 is greater than the height of the keycap of the keyboard assembly 201. The protrusion 202 can prevent the keyboard assembly 201 from abrading against the screen of the electronic device when the protective cover is buckled in the right position, and can also prevent the keyboard assembly 201 from directly contacting the placement platform of the electronic device when the protective cover is buckled in the reverse position, thereby preventing the keyboard assembly 201 from being squeezed or abraded.

[0047] Please refer to Figure 2 In some embodiments, the control module includes a controller 401 and a communication component 402. The controller 401 is electrically connected to the keyboard component 201, the Hall sensor 301 and the communication component 402, respectively, and the communication component 402 is used to establish a communication connection with the electronic device. Based on the communication connection, the controller 401 can send the key position information input by the user through the keyboard component 201 to the electronic device, or perform other types of data interaction with the electronic device.

[0048] Please refer to Figure 3, exemplarily, the communication component can be a wired communication component 4021. At this time, the protective cover also includes a communication interface 403. The communication interface 403 is arranged on the first cover plate or the second cover plate, and is electrically connected to the wired communication component 4021. Among them, the communication interface 403 can be a USB communication interface or a pogo pin communication interface, which is not limited in the embodiments of the present disclosure. The electronic device 500 can be connected to the communication interface 403 via a data cable or direct docking, so as to power the keyboard assembly 201, the Hall sensor 301 and the control module in the protective cover through the communication interface 403, and can realize data transmission between the protective cover through the interface.

[0049] Please refer to Figure 4 , exemplarily, the communication component may be a wireless communication component 4022. For example, a Bluetooth module, a WiFi module, etc. At this time, the protective cover further includes a power supply module 600. The power supply module 600 is used to supply power to the keyboard component 201, the Hall sensor 301, and the control module. For example, the power supply module 600 may be a battery.

[0050] In this example, in order to save the power of the power supply module 600 and improve the battery life of the keyboard assembly 201, the communication connection between the wireless communication component 4022 and the electronic device 500 can also be disconnected through the controller 401 when it is determined that the protective cover is in the right buckle state. Among them, the communication connection between the wireless communication component 4022 and the electronic device 500 can be disconnected immediately when it is determined that the protective cover is in the right buckle state; or when it is determined that the protective cover is in the right buckle state, after a certain period of time, the communication connection between the wireless communication component 4022 and the electronic device 500 is disconnected (that is, it is determined that the protective cover is continuously in the right buckle state, and the user does not need to continue to use the electronic device 500 in a short time). When it is determined that the protective cover is in the reverse buckle state, since the electronic device 500 is still in use, in order to be able to respond to the user's operation requirements for the keyboard assembly 201 at any time, the communication connection between the wireless communication component 4022 and the electronic device 500 can be maintained.

[0051] As can be seen from the above content, when the protective cover is in the forward buckle state or the reverse buckle state, the Hall sensor 301 of the protective cover will be triggered by the magnet. Therefore, in order to correctly distinguish the forward buckle state and the reverse buckle state of the protective cover, when the Hall sensor 301 is in the triggered state, the controller 401 can determine the buckle state of the protective cover according to the sensor data of the electronic device 500 received by the communication component.

[0052] Exemplarily, when the Hall sensor 301 of the protective cover is in a triggered state, the controller 401 may send a sensor data acquisition request to the electronic device 500 through the communication component. The electronic device 500 may respond to the sensor data acquisition request and return the sensor data of the electronic device 500 to the controller 401. The sensor data may be at least one of distance sensor data, light sensor data, and magnetic sensor data (when the Hall sensor 301 of the protective cover is disposed inside the first cover plate and the magnet is disposed inside the second cover plate), depending on the sensor setting in the electronic device 500.

[0053] Since the distance sensor, light sensor and magnetic sensor are usually installed on the front side (user interaction side) of the electronic device 500, when the Hall sensor 301 of the protective cover is in the triggered state, if it is detected that the distance between the electronic device 500 and the object in front of it is significantly shortened, or the light intensity in the front is significantly reduced, or the magnetic field intensity in the front is significantly increased (when the Hall sensor 301 of the protective cover is arranged inside the first cover plate and the magnet is arranged inside the second cover plate), it can be determined that the protective cover is in the forward buckle state, and the communication connection between the wireless communication component 4022 and the electronic device 500 can be disconnected at this time to save the power of the power supply module 600. Otherwise, it can be determined that the protective cover is in the reverse buckle state.

[0054] Exemplarily, after the communication connection between the wireless communication component 4022 and the electronic device 500 is disconnected, if it is detected that the Hall sensor 301 of the protective cover is in an untriggered state, the communication connection between the wireless communication component 4022 and the electronic device 500 can be restored to respond to the user's demand for use of the keyboard component 201.

[0055] Based on the same concept, an electronic device is also provided in the embodiment of the present disclosure, including an electronic device body and the above-mentioned protective cover. The electronic device body is fixed on the first cover. Since the principle of solving the problem in the electronic device embodiment is similar to that in the above-mentioned protective cover embodiment, the implementation of the electronic device embodiment can refer to the implementation of the above-mentioned protective cover embodiment, and the repeated parts will not be repeated.

[0056] The embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0057] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
