Detailed Description

For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.

It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments.

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be noted that the terms "upper" and "lower" used in the embodiments of the present application are used in the angle shown in the drawings, and should not be construed as limiting the embodiments of the present application.

With the development of technology, electronic devices (such as mobile phones, tablet computers, notebook computers, etc.) have become communication devices commonly used in daily life of people, and in general, people connect a keyboard to the electronic devices externally or integrate the keyboard into the electronic devices, so that the electronic devices have a physical keyboard, which improves the typing accuracy. When a user needs to perform a touch operation, the user still needs to move a finger to a touch area (e.g., a screen or a touch pad of the electronic device) set by the electronic device to perform the touch operation, and therefore, when the user needs to switch between the key input and the touch input, the user needs to continuously move the finger between the keyboard and the touch area, which is very inconvenient in use and greatly affects the input efficiency.

When the electronic device is a touch screen structure, usually, a keyboard with physical keys is covered at a corresponding position of a screen of the electronic device, and when performing key input, a user moves the keys toward a direction close to the electronic device by tapping the corresponding keys, and contacts the screen of the electronic device through the keys to replace fingers of the user to tap virtual keys displayed on the screen of the electronic device, so as to achieve the purpose of inputting characters, however, in such a manner, the keyboard still only can achieve key input, but cannot achieve touch input, and because the physical keyboard occupies a space of the screen, when the user needs to perform touch input, the keyboard covered at the screen position needs to be detached to perform touch operation, and when the user switches between key input and touch input, the user needs to repeatedly install and detach the keyboard, the operation is very inconvenient, and in the mode, because the keys of the keyboard can repeatedly knock the screen when the keys are input, the surface of the screen is easily damaged by scratches and the like, and the service life of the screen is influenced.

As shown in fig. 1, a conventional keyboard of an electronic device may include a key 1 ', an elastic conductive sheet 2 ', a touch sensing sheet 3 ' integrated with a capacitive sensing chip, a supporting member 4 ', a light emitting member 5 ', and a light guiding sheet 6 ', wherein when the key 1 ' is pressed, the key 1 ' triggers the elastic conductive sheet 2 ' to change a connection mode or on/off of a control circuit inside the keyboard, so as to switch between key input and touch input. However, due to the design, the structure of the keyboard is too complex, a circuit needs to be arranged in the keyboard, the processing difficulty is high, the cost is high, and the actual production requirement is not met.

In view of this, embodiments of the present application provide an electronic device assembly, a keyboard, and an electronic device, so that the keyboard assembly, the keyboard, the electronic device assembly including the keyboard assembly, or the electronic device including the keyboard can implement key input and touch input.

As shown in fig. 2, an embodiment of the present application provides an electronic device assembly, where the electronic device 2 has a screen 21, a keyboard assembly a can cover an area of the screen 21 where virtual keys of an input method are displayed, the electronic device 2 can be a touch screen device such as a mobile phone and a tablet computer, as shown in fig. 3, in one possible design, the electronic device 2 can be a touch screen device with a folding screen structure, the electronic device 2 can include at least two screens 21, and when in use, a certain included angle can be formed between the screens 21 so as to be convenient for a user to use, specifically, one of the screens 21 can be used for displaying virtual keys of an input method, and the keyboard assembly a can be placed on the screen 21 so that the keyboard assembly a can cooperate with a first touch layer 22 of the screen 21 of the electronic device 2 so as to implement an input operation. As shown in fig. 4, the keyboard assembly a may include a mounting bracket 12 and a key 11, the key 11 is mounted on the mounting bracket 12, when the user presses the key 11, the key 11 can move downward relative to the mounting bracket 12 along the thickness direction Z of the keyboard assembly a, and the key 11 can also move upward relative to the mounting bracket 12 to return to the original position.

It should be noted that the keyboard assembly a provided in the embodiment of the present application can be applied not only to the electronic device 2 with a foldable screen, but also to other electronic devices 2 with a touch screen structure.

Specifically, as shown in fig. 5, a sensing part 111 is disposed on a side of the key 11 facing the mounting bracket 12 along the thickness direction Z of the keyboard assembly a, the sensing part 111 is connected to the key 11, the screen 21 may have a first touch layer 22, and the first touch layer 22 may be located on a side of the screen 21 away from the keyboard assembly a. The sensing component 111 and the first touch layer 22 have a predetermined distance therebetween, and when the distance between the sensing component 111 and the first touch layer 22 changes, the capacitance of the first touch layer 22 also changes, so that the capacitance of the first touch layer 22 can be changed by pressing the key 11, thereby implementing a corresponding input operation.

The sensing component 111 may be made of carbon particles, iron sheets, or other materials capable of causing a change in a sensing capacity of the first touch layer 22, and the sensing component 111 may be disposed on the key 11 by injection molding or adhesion during processing.

Specifically, when inputting, the user presses the key 11 to gradually decrease the distance between the sensing part 111 of the key 11 and the first touch layer 22, and gradually increase the sensing capacity of the first touch layer 22, so that the electronic device can recognize the input signal, when inputting is completed, the key 11 moves in the direction away from the screen 21 along the thickness direction Z of the keyboard assembly a, the distance between the sensing part 111 and the first touch layer 22 gradually increases, the sensing capacity of the first touch layer 22 gradually decreases, and the key 11 returns to the original position. Therefore, a threshold range of the induction capacity value can be preset, the threshold range can include a first threshold range and a second threshold range, and the maximum value of the first threshold range is smaller than the minimum value of the second threshold range. When inputting, when a user needs to perform touch input, the user can slide on the surface of the key 11 by a finger, at this time, the descending distance of the key 11 is small, the key 11 moves to the first position relative to the mounting bracket 12, the change of the induced capacitance value of the first touch layer 22 caused by the movement is also relatively small, and when the magnitude of the induced capacitance value is within the first threshold range, the electronic device 2 recognizes the input signal as a touch signal, so that the user can perform touch input; when a user needs to perform key input, the corresponding key 11 can be pressed by a finger, the key 11 moves to the second position relative to the mounting bracket 12, and when the sensing capacitance value of the first touch layer 22 is within the range of the second threshold range, the electronic device 2 recognizes the input signal as a key signal, so that the user can perform key input.

Specifically, when the user performs key input, the displacement amount of the key 11 with respect to the mounting bracket 12 is larger than the displacement amount of the key 11 with respect to the mounting bracket 12 during touch input.

In practical use, the keyboard assembly a is connected with the electronic device, and specifically, simulation software of the electronic device can be opened to record corresponding input of the keyboard assembly a and change of the sensing capacity. The user can move on the keyboard component A through fingers or a touch pen and the like, because the acting force applied to the key 11 is small at the moment, the displacement generated by the key 11 is also small, the key 11 moves to a first position, the induction capacity value of the first touch layer 22 is in the range of a first threshold range, the electronic equipment 2 collects the positions where the induction capacity value changes and connects the positions, the track of the user moving can be displayed on a screen, when the user presses a certain key 11, because the displacement of the key 11 is large, the key 11 moves to a second position, the induction capacity value is in a second threshold range at the moment, the electronic equipment identifies the position where the induction capacity value changes greatly, and corresponding characters are input.

It should be noted that, in the embodiments of the present application, neither the first location nor the second location is a specific location, and both the first location and the second location may be a range, and the range of the first location and the range of the second location are different, that is, the range of the first location does not have a portion overlapping with the range of the second location.

Specifically, in a possible implementation manner, a part of gestures may be pre-entered in a control component (e.g., a motherboard, etc.) of the electronic device 2, each gesture may correspond to a different function, when the first touch layer 22 recognizes a corresponding gesture, a signal may be sent to the control component, and the corresponding function may be called, and the function corresponding to each gesture may be described in a user manual or a UI interface.

As shown in fig. 6, in one possible implementation, the gestures and functions included in the control unit are as follows: the left key of the mouse can be double-clicked by a single finger when the keyboard component is knocked, a cursor can be moved by the single finger when the keyboard component is scratched, a designated target can be dragged by the single finger after the keyboard component is pressed for a long time, a right click function of the mouse can be realized by the double finger when the keyboard component is knocked, a page dragging function can be realized by the double finger when the keyboard component is scratched, a page shrinking or amplifying function can be realized by the double finger when the keyboard component is close to or far away from the scratch, a voice assistant function can be realized by the three finger when the keyboard component is knocked, a multi-task management function can be realized by the three finger when the keyboard component is scratched, and a task center function can be realized by the four finger when the keyboard component is knocked.

It should be noted that, the gestures and functions provided in the embodiments of the present application include, but are not limited to, the gestures, functions and corresponding relationships mentioned above, other gestures such as four-finger strokes, and other functions such as page turning, and may also be implemented in the solutions provided in the embodiments of the present application, and are not described herein again.

Can cooperate through keyboard subassembly A and touch screen equipment through foretell mode to make the user carry out key input and touch-control input through keyboard subassembly A, make keyboard subassembly A's function abundanter, it is more convenient when in-service use. Compare simultaneously in setting up the motor at touch screen equipment, carry out the mode of vibrations, the keyboard subassembly A that this application embodiment provided feels more and is close to the keyboard when the in-service use, can promote user's use and experience.

In a possible implementation manner, the maximum value of the second threshold range may be smaller than the sensing capacitance value of the first touch layer 22 when the sensing component 111 contacts the first touch layer 22, and in this manner, when a user performs key input, corresponding input may be completed without the sensing component 111 contacting the first touch layer 22, and in this manner, a preset distance may be provided between the key 11 and the first touch layer 22, so that the impact of the key 11 on the screen 21 during the input process is greatly reduced, and the possibility that the screen 21 is damaged during the input process is reduced.

In addition, when the user inputs through the virtual keyboard displayed on the screen 21, since there is no physical key, the user cannot determine the position of each virtual key and whether the corresponding virtual key is pressed accurately by the touch sense during inputting, and the situation that the wrong virtual key is pressed by a finger or a plurality of virtual keys are pressed simultaneously is likely to occur, which results in the decrease of the input accuracy. Through the keyboard 1 provided by the embodiment of the application, when a user inputs, the position of each key 11 can be determined through touch, and the input accuracy can be improved.

As shown in fig. 5, in a possible implementation manner, the keyboard assembly a of the electronic device 2 may further include a key cap 112 and a reset component 121, the key cap 112 is mounted on the mounting bracket 12 through the reset component 121, and when a user performs a typing input, the knocked key cap 112 can automatically return to an original position under the action of the reset component 121, so that the user can repeatedly knock the key 11.

In a possible implementation manner, the reset component 121 may be a rubber component, and since the rubber material has good elasticity, the user can quickly restore the key 11 to the original position by the restoring force after pressing the key 11, so as to reduce the possibility that the sensing capacity of the first touch layer 22 is within the preset threshold range for a long time due to the long time required for resetting the key 11, which leads to repeated input.

As shown in fig. 5, in a possible implementation manner, the key 11 may further be connected to the mounting bracket 12 through a first connecting member 122 and a second connecting member 123, the first connecting member 122 and the second connecting member 123 intersect to form an "X" structure, and either one of the two can rotate relative to the other, as shown in fig. 5, one side of the keycap 112 facing the reset component 121 is provided with a plurality of first mounting grooves 113, the mounting bracket 12 is provided with a plurality of second mounting grooves 124, one end of the first connecting member 122 is located in the first mounting groove 113, the other end is located in the second mounting groove 124, one end of the second connecting member 123 is located in the first mounting groove 113, the other end is located in the second mounting groove 124, and the first connecting member 122 and the second connecting member 123 can move along the first mounting groove 113 and the second mounting groove 124, respectively. When a user presses the key 11, the first connecting piece 122 and the second connecting piece 123 rotate relatively, the two opposite ends of the first connecting piece 122 and the two opposite ends of the second connecting piece 123 move along the first mounting groove 113 and the second mounting groove 124 respectively, and along the thickness direction Z of the keyboard assembly a, the height of the key cap 112 can be reduced, so that the key 11 can be pressed, when the key 11 is reset, along with the increase of the height of the key cap 112, the first connecting piece 122 and the second connecting piece 123 also recover to the original positions, and meanwhile, the ends of the first connecting piece 122 and the second connecting piece 123 connected with the key cap 112 are respectively located at the two opposite ends of the key cap 112 facing one side of the mounting bracket 12, so that the key 11 can be stressed more uniformly when pressed actually, the service life of the key 11 is prolonged, the hand feeling of the user when typing can be improved, and fatigue is relieved.

In a possible implementation manner, the middle parts of the first connecting piece 122 and the second connecting piece 123 can be connected through a shaft, and such a design can make the first connecting piece 122 and the second connecting piece 123 more stable during movement, further improving the hand feeling of the keyboard assembly a.

As shown in fig. 7, in a possible implementation manner, the keyboard assembly a is connected to the electronic device 2 through a connecting component, specifically, the mounting bracket 12 may be provided with a first magnetic component 125, and when in use, the mounting bracket 12 may be magnetically attached to the electronic device 2 through the first magnetic component 125, such a design can reduce the possibility that the keyboard assembly a moves relative to the electronic device 2 during use, thereby reducing the possibility that the keys 11 cannot correspond to the virtual keys displayed on the screen 21 due to the movement of the keyboard assembly a relative to the electronic device 2, and thus improving the accuracy of input.

Specifically, as shown in fig. 7, in one possible design, the electronic device 2 may be provided with a second magnetic component 23, and the first magnetic component 125 may be magnetically attached to the second magnetic component 23, so that the keyboard assembly a may be magnetically attached to the electronic device 2, thereby improving the connection stability of the keyboard assembly a and the electronic device 2.

In a possible implementation manner, the electronic device 2 has a detection component, the detection component can be used to detect whether the keyboard assembly a is connected to the electronic device 2, and when the detection component detects that the keyboard assembly a is connected to the electronic device 2, the detection component can send a signal to enable the corresponding position of the screen 21 to display the user interface of the input method. In a possible implementation manner, the detecting component may be a hall device, when the keyboard assembly a is connected to the electronic device 2, the hall device is located in a magnetic field generated by the first magnetic component 125, and due to a hall effect, the hall device can generate a current in the magnetic field, and when the electronic device 2 detects the current generated in the hall device, the electronic device 2 can recognize that the keyboard assembly a is connected to the electronic device 2, and enable a corresponding position of the screen 21 of the electronic device 2 to display a user interface of an input method, so as to perform input in cooperation with the keyboard assembly a.

As shown in fig. 8, in a possible implementation manner, the key cap 112 may be designed to be a transparent structure, at this time, a user may observe a virtual key through the key cap 112, and strike the corresponding key cap 112 according to a mark corresponding to the virtual key, the key cap 112 may also be an opaque structure, at this time, a corresponding mark may be disposed on an outer surface of the key cap 112, so that the user can know a character or a function corresponding to each key 11, however, since there is a certain difference in user interfaces of different regions or different input methods, when the keyboard assembly a is applied to electronic devices in different regions or different input methods, the mark of the key cap 112 and the character or the function corresponding to the virtual key displayed at the corresponding position of the electronic device 2 may be inconsistent, and therefore, the user cannot determine an actual function of each key, which may easily cause an input error, the accuracy of input is reduced, and when the keys 11 are of a transparent structure, corresponding marks do not need to be arranged on the keys 11, and a user can observe virtual keys displayed on the screen 21 of the electronic device 2 through the keys 11 to determine input contents corresponding to the keys 11, so that the accuracy of input is improved, and further, in order to reduce the virtual keys displayed on the screen 21 observed by the user, other components such as the mounting bracket 12 of the keyboard assembly a and the like can also be arranged to be of a transparent structure.

In a possible implementation manner, the processing materials of the keycap 112 and the mounting bracket 12 can be transparent plastics, and the plastics have strong plasticity, so that the processing difficulty can be reduced, and meanwhile, the method also has the advantage of lower cost, and meets the requirement of actual production.

Specifically, as shown in fig. 10, in one possible implementation, the keyboard 1 may include a main body portion including the keys 11, the mounting bracket 12, and the second touch layer 142. The main body portion may also include other electronic components such as a motherboard. The key 11 and the second touch layer 14 are both arranged on the mounting bracket 12, the key 11 is provided with a sensing component 111, when a user uses the keyboard 1, the sensing component 111 can change the sensing capacity value of the second touch layer 14, and the processor of the electronic device judges whether the user is performing key input or touch input according to whether the sensing capacity value is in a first threshold range or a second threshold range, so as to complete corresponding input operation.
