DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] The protective cover for the electronic device provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0029] like Figures 1 to 5As shown, an embodiment of the present application discloses a protective cover for an electronic device, which includes a protective cover body 1000 and a keyboard 2000 .

[0030] The protective cover body 1000 includes a first support plate 1100 and a second support plate 1200, and the first support plate 1100 is rotatably connected to the second support plate 1200. The first support plate 1100 and the second support plate 1200 can be used to install and carry electronic devices, and can also be used to protect electronic devices from scratches and other damage. In an optional embodiment, the first support plate 1100 is rotatably connected to the second support plate 1200 through a hinge mechanism, and the hinge mechanism can be a component with a rotation function such as a rotating shaft. The hinge mechanism here can be a rigid structure, so that the connection strength of the first support plate 1100 and the second support plate 1200 is higher, and the relative position of the two is easier to ensure. In another embodiment, the first support plate 1100 is rotatably connected to the second support plate 1200 through a flexible member, and the flexible member here can be a structure made of soft material. This embodiment realizes the rotatable connection of the first support plate 1100 and the second support plate 1200 through the structural characteristics of the flexible member itself, and the structure is simpler, and the weight is light, which is easy to carry.

[0031] The keyboard 2000 can be arranged on one end of the upper surface of the second support plate 1200 away from the first support plate 1100, so that the position on the upper surface of the second support plate 1200 where the keyboard 2000 is not arranged can be used to support the electronic device. The keyboard 2000 may include a plurality of keys, including at least one first key 2100, the first key 2100 includes a keycap 2110 and a touch component 2120, the keycap 2110 has a first surface 2111 away from the protective cover body 1000, and the touch component 2120 is arranged on the first surface 2111, thereby forming a touch function area of ​​the keyboard 2000. In addition, optionally, the touch component 2120 may include a substrate 2121 and a touch panel 2122, the touch panel 2122 is arranged on the side of the substrate 2121 away from the protective cover body 1000, and the touch panel 2122 is provided with a plurality of touch electrodes 2122a. The touch control assembly 2120 may further include a cover plate 2123, which is bonded to the touch panel 2122 and is located on the side of the touch panel 2122 away from the substrate 2121. In other words, the substrate 2121, the touch panel 2122 and the cover plate 2123 are stacked, and the touch panel 2122 and the cover plate 2123 may be bonded using double-sided tape, so that the cover plate 2123 may be better used to protect other components. The cover plate 2123 may be a component made of plastic, glass or other materials, and the embodiment of the present application is not limited thereto.

[0032] In an embodiment of the present application, the user can install the electronic device on the protective cover, and then connect the protective cover to the electronic device by wire or wirelessly, so that the user can perform input operations on the electronic device through the keyboard 2000 on the protective cover. When the user needs to move the cursor, it can be done by touching the first button 2100, which is convenient for the user to perform touch operations. At the same time, there is no need to set a separate touchpad on the protective cover of the electronic device, so that a larger-scale keyboard 2000 can be set, which is convenient for the user to perform text input operations, and the user does not need to use an external device to move the cursor. Therefore, this solution can improve the operability of the keyboard 2000 combined with the protective cover of the electronic device.

[0033] In one embodiment, when the user needs to prop up the electronic device for use, the electronic device can be supported by an auxiliary support member, and when the electronic device is connected to the keyboard 2000, it can be connected through an additionally provided connecting line. However, in this way, the user needs to carry multiple accessories, which makes it more troublesome for the user to use the keyboard 2000. Therefore, a bottom bracket 1210 is provided at one end of the upper surface of the second support plate 1200 close to the first support plate 1100, and the touch assembly 2120 is electrically connected to the bottom bracket 1210. The number of the bottom bracket 1210 can be one, which can be a bar structure or other types of structures. The bar-shaped bottom bracket 1210 can better support the electronic device. When the user uses the electronic device, on the one hand, the electronic device can cooperate with the second support plate 1200 through the base 1210, so that the electronic device can stand up, which makes it more convenient for the user to use the electronic device; on the other hand, since the touch component 2120 is electrically connected to the base 1210, the electronic device can be directly connected to the keyboard 2000 through the base 1210, so that the cursor on the screen of the electronic device can be controlled through the touch component 2120, which is not only beneficial for the user to control the electronic device, but also the user does not need to carry extra accessories, which makes it more convenient for the user to use the keyboard 2000.

[0034] In an optional embodiment, Figure 6 to Figure 7 As shown, there are multiple bases 1210, and at least two bases 1210 are provided with connection contacts 1211. When the electronic device is electrically connected to the connection contacts 1211 of different bases 1210, the keyboard 2000 can be switched to different working states. The user can choose different bases 1210 to connect with the electronic device according to their own habits, and change the tilt angle of the protective cover supporting the electronic device, so as to make it more convenient for the user to use the electronic device. In addition, the user can also electrically connect the electronic device to the connection contacts 1211 of different bases 1210 according to their own work needs, so as to switch the keyboard 2000 to different working states to meet the different usage needs of the user.

[0035] In a further optional embodiment, the base 1210 includes a first base and a second base. When the electronic device is electrically connected to the connection contact 1211 of the first base, the first key 2100 in the first area of ​​the keyboard 2000 is in a powered-on state; when the electronic device is electrically connected to the connection contact 1211 of the second base, the first key 2100 in the second area of ​​the keyboard 2000 is in a powered-on state; wherein the first area and the second area partially overlap, or the first area is located outside the second area. When the user electrically connects the electronic device to the connection contact 1211 of the first base, the user can perform touch operations in the first area of ​​the keyboard 2000; when the electronic device is electrically connected to the connection contact 1211 of the second base, the user can perform touch operations in the second area of ​​the keyboard 2000. Therefore, the user can choose to support the electronic device on the first base or the second base according to his or her own usage habits, so as to perform touch operations in the first area or the second area, which can further improve the operability of the keyboard 2000.

[0036] The touch component 2120 is usually a relatively sensitive component and is easily corroded by the aggressors in the external environment. Therefore, in order to protect the touch component 2120 from the aggressors such as dust and water vapor in the external environment, the keycap 2110 may be provided with a groove 2112, the first surface 2111 is the bottom surface of the groove 2112, and the touch component 2120 is arranged in the groove 2112. In this way, the groove 2112 can protect the touch component 2120 and reduce the corrosion of the aggressors as much as possible, thereby extending the service life of the touch component 2120. In addition, the groove 2112 can also facilitate the installation of the touch component 2120, and can assist in limiting the touch component 2120 when installing the touch component 2120, and can also reduce the extra space occupied by the touch component 2120, which is conducive to realizing the thin design of the protective cover.

[0037] A touch function area that is too small may easily lead to accidental touches and may be inconvenient for users to use. Therefore, the number of first buttons 2100 is at least two. By combining and superimposing the touch functions of the first buttons 2100 and then combining them with software algorithm recognition, the same sliding touch function as that of a conventional touchpad can be achieved on the buttons. In this way, a larger touch function area can be achieved without occupying the area of ​​the button area, thereby improving the operability of the keyboard 2000.

[0038] Furthermore, the first buttons 2100 are arranged adjacent to each other. The adjacently arranged first buttons 2100 can form a relatively concentrated touch function area, and the concentrated touch function area is more convenient for the user to perform touch operation.

[0039] In a further optional embodiment, the first buttons 2100 are arranged in a matrix. The first buttons 2100 arranged in a matrix are more regularly arranged and conform to the existing arrangement of buttons, so they can accommodate as many user groups as possible.

[0040] In one embodiment, all the buttons are first buttons 2100. In this way, the touch function area is the entire keyboard 2000, and the user can perform touch operations in any area on the keyboard 2000 without moving to the touch function area for touch operations, which makes it easier for the user to operate the cursor on the screen of the electronic device and improves the user's work efficiency. However, the entire keyboard 2000 is a touch function area, and the probability of misoperation is very high. Therefore, in other embodiments, the protective cover body 1000 can also have a touch area 1300 and a non-touch area 1400, and the non-touch area 1400 is located outside the touch area 1300, and the first button 2100 is provided in the touch area 1300. The touch area 1300 is a touch function area, and the user can perform both touch operations and key operations in the touch area 1300. In the non-touch area 1400, the user can only perform key operations. Therefore, by distinguishing the touch area 1300 from the non-touch area 1400, the user's misoperation during touch operation can be reduced, thereby improving the user's control efficiency.

[0041] The present application also discloses a device assembly, which includes an electronic device and a protective cover in any of the above embodiments, and the electronic device can be connected to the protective cover. When the electronic device is connected to the protective cover, the user can perform input operations and touch operations on the electronic device through the keyboard 2000 on the protective cover.

[0042] The embodiment of the present application further discloses a control method of an electronic device, the electronic device can be connected to the protective cover described in any of the above embodiments, and the control method includes:

[0043] S110, obtaining the connection status between the electronic device and the protective cover;

[0044] Optionally, when the electronic device is in contact with the base 1210 on the protective cover, the keyboard 2000 can identify that the electronic device and the protective cover are in an electrically connected state.

[0045] S120: When the electronic device is electrically connected to the protective cover, a touch operation of the first button 2100 is obtained.

[0046] After the keyboard 2000 recognizes that the electronic device and the protective cover are in an electrically connected state, the touch function of the first button 2100 is activated, and the user can perform touch operations on the electronic device through the first button 2100. The touch operations input by the user can be obtained, thereby facilitating the implementation of corresponding operations.

[0047] In the above manner, when the electronic device and the protective cover are not connected, the keyboard 2000 on the protective cover does not need to implement the touch function; when the electronic device and the protective cover are electrically connected, the touch operation of the first button 2100 is obtained. At this time, the user can perform touch operation on the electronic device through the first button 2100, which can reduce the power consumption of the protective cover so that the working time of the protective cover can be longer. In addition, the user can directly move the cursor on the electronic device through the first button 2100, and there is no need to set a separate touchpad on the protective cover of the electronic device, and the user does not need to use an external device to move the cursor. Therefore, the keyboard 2000 on the protective cover can be set larger, so as to facilitate the user to perform text input operations, so as to improve the operability of the keyboard 2000 combined with the protective cover of the electronic device.

[0048] In a further embodiment, before S120, the method further includes:

[0049] S111, obtaining a button setting operation;

[0050] The user can input key setting operations by touching the keys on the keyboard 2000 .

[0051] S112. According to the key setting operation, obtain a target first key corresponding to the setting operation of the keyboard 2000.

[0052] The user can set the corresponding target first key at different positions of the keyboard 2000 according to his or her preferences.

[0053] At this time, obtaining the touch operation of the first button 2100 in S120 specifically includes: obtaining the touch operation of the target first button.

[0054] The user can move the cursor on the electronic device by touching the first button 2100 .

[0055] In this way, before the user uses the keyboard 2000, the user can first start the key setting operation through the touch operation, and then set the first key 2100. When the electronic device is connected to the protective cover, the user can select the corresponding target first key according to the pre-set correspondence, and then touch the target first key to control the cursor on the screen of the electronic device. In this way, the user can set different first keys 2100 at different positions of the keyboard 2000, so that it is more convenient for the user to use the touch function on the keyboard 2000. Optionally, the user can divide the area where the keyboard 2000 is located into a first area and a second area. The size of the first area and the second area can be flexibly set. Touching the first key 2100 in the first area from left to right can realize the operation of zooming in on the page, touching the first key 2100 in the first area from right to left can realize the operation of zooming out on the page, touching the first key 2100 in the second area from top to bottom can realize the operation of moving up the page, and touching the first key 2100 in the second area from bottom to top can realize the operation of moving down the page.

[0056] Alternatively, if Figure 8 As shown, an embodiment of the present application also provides an electronic device 3000, including a processor 3100, a memory 3200, and a computer program stored in the memory 3200 and executable on the processor 3100. When the program is executed by the processor 3100, the steps of the above method are implemented and the same technical effect can be achieved. To avoid repetition, it will not be described here.

[0057] It should be noted that the electronic devices in the embodiments of the present application include the mobile electronic devices and non-mobile electronic devices.
