[0030] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0031] Input devices generally include components such as word keys, buttons, and joysticks for receiving user operation instructions. Users can achieve specific functions by operating these components. For example, a keyboard is one of the commonly used input devices, which is used to input information such as text and numbers into a computer. A game controller is an input device designed specifically for electronic games. It usually contains multiple buttons, joysticks, and triggers. Users can control the characters in the game or execute game commands by operating these mechanical components. The button and joystick design of the game controller allows users to have a more intuitive and realistic operation experience when playing games. A foot switch is also a device that inputs instructions by stepping on it. By stepping on different positions on the foot switch, users can send specific signals or perform preset operations to improve work efficiency. Regardless of the type of input device, the components set on the input device for receiving user operation instructions are fixed in layout and cannot meet the personalized needs of users.

[0032] This embodiment takes the keyboard as an example. The current keyboard character layout is mainly based on the traditional QWERTY layout, with the purpose of slowing down typing and avoiding "stuck" mechanical structures inside the typewriter. This layout places commonly used characters in the corners and on the left side, reducing the probability of adjacent keys being pressed quickly and continuously, and assigns the main keystroke tasks to the left hand. However, this fixed layout cannot be flexibly configured according to user needs. Based on this, the disclosed embodiment provides an input device that can adjust the layout of character keys according to user needs.

[0033] like Figure 1 A schematic structural diagram of an input device provided in an embodiment of the present disclosure is shown. The input device includes: a character key 1 and a circuit board 2.

[0034] The character key 1 is arranged above the circuit board 2, and a slot is provided on the circuit board 2, and the character key 1 is plugged into the slot. There are multiple character keys 1, and each character key 1 is used to input a different target operation. For example, taking the character key 1 in the keyboard as an example, the character key 1 includes common key positions such as letter keys AZ, number keys 0-9, function keys F1-F12, Shift key, Ctrl key, Enter key, and space key.

[0035] Each character key 1 is provided with a corresponding fixed matrix line 11 for implementing the target operation corresponding to the character key 1. The fixed matrix line 11 includes a matrix structure composed of row lines and column lines. At least one of the row lines and column lines corresponding to each character key 1 is different. Each character key 1 is connected to the intersection of a specific row line and column line. When a character key 1 is pressed, it sends an electrical signal through the connected row line and column line. This signal will be received and decoded by the keyboard control system, thereby identifying the pressed character key 1. Figure 2 The distribution diagram of the word key 1 and the matrix circuit diagram of the word key 1 are shown. At the y0-y17 end, high-level scanning circuits are added one by one, and receiving monitoring is performed at the x0-x7 end. When the y10-x7 circuit is turned on, it can be recognized that the 61 key position (space key) is pressed, and the corresponding function is realized. Based on this, a fixed matrix circuit 11 is designed on each word key 1, such as Figure 3 The diagram shows the fixed matrix circuit 11 of some word keys 1. For example, the fixed matrix circuit of key A is Y0-X4, that is, Figure 3 The line connecting Y0 and X4 in the B key is Y1-X5, that is, Figure 3 The line connecting Y1 and X5 in the C key is Y2-X6, that is, Figure 3 The fixed matrix line of the D key is Y3-X7, that is, the line connecting Y3 and X7. Similarly, all word keys 1 have independent and different matrix lines. Figure 2 The capital letters X and Y in the middle row and column lines are Figure 3 The lowercase letters x and y in the row and column lines of the specific word key 1 have the same meaning, that is, X1=x1.

[0036] like Figure 4As shown, the word key 1 also includes a contact element 12. When the word key 1 is pressed, the contact element 12 is closed and connected to the fixed matrix line 11, so that a path is formed between the row line and the column line corresponding to the word key 1. The contact element 12 is set at the center of the word key 1. When the contact element 12 is closed, it will complete a circuit loop, so that a path is formed between the row line and the column line corresponding to the word key 1. This path can transmit electrical signals or currents, thereby triggering corresponding functions or recording key input. In one embodiment, the contact element 12 can adopt a spring structure. When the word key 1 is pressed, the spring is connected to the row line and the column line on the word key 1 to form a fixed matrix line 11.

[0037] like Figure 5 As shown, the circuit board 2 includes a control circuit composed of multiple circuits, and the control circuit is electrically connected to the character key 1 to receive input information of the target operation corresponding to the character key 1. The control circuit includes a reserved interface 21 corresponding to the character key 1, and the reserved interface 21 is distributed in a matrix in the control circuit, and the reserved interface 21 forms a one-to-one correspondence with the character key 1. That is, each interface point reserved interface 21 can be connected to the fixed matrix line 11 of a character key 1, so as to realize the communication between the character key 1 and the keyboard circuit board 2. The reserved interface 21 includes an input end and an output end. When the character key 1 is pressed, the input end is electrically connected to the fixed matrix line 11 of the character key 1. The input end is responsible for receiving the key signal from the character key 1. When the user presses the character key 1, the fixed matrix line 11 of the character key 1 will send an electrical signal to the corresponding open matrix reserved interface 21. These signals are transmitted to the corresponding input end through the line of the character key 1. The control chip set on the circuit board 2 will monitor these input signals. When the key action is detected, it will perform corresponding processing. After processing the key signal, the control system will send the processed signal to the computer or other electronic devices through the output end. The computer can then recognize the user's key operation and execute the corresponding command or operation.

[0038] When the character key A is connected to the reserved interface 21, the fixed matrix circuit 11 corresponding to the character key A just connects Y0-X4, thereby realizing the function of the character key A. No matter which reserved interface 21 the character key A is connected to, the function of the letter "A" can be realized. This solution provides great flexibility by setting a reserved interface 21 corresponding to the character key 1. The user can place the character key 1 at any position on the keyboard according to his or her needs, and only needs to connect the fixed matrix circuit 11 of the character key 1 to the corresponding reserved interface 21. This flexibility allows the keyboard to be customized according to the user's personal preferences and usage habits, thereby improving the user's usage experience. Since in actual use, the character keys 1 of the keyboard are of different sizes, for example, the letter keys are the same size, the function keys are the same size, and the character keys 1 of different sizes cannot be replaced, and can only be replaced with the same size character keys 1. In one embodiment, the sizes of all the character keys 1 of the keyboard can also be unified, so that flexible adjustment of all the character keys 1 can be achieved, and the present disclosure does not limit this.

[0039] In addition, the open matrix reserved interface 21 has a certain degree of expansibility. If the user needs to add more character keys 1 or functions, it is only necessary to add the corresponding reserved interface 21 on the keyboard circuit board 2, and the fixed matrix circuit 11 of the character keys 1 is designed accordingly, so that the keyboard can adapt to the needs and scenarios of different users, thereby improving the versatility and practicality of the keyboard.

[0040] Since a plurality of reserved interfaces 21 are arranged on the circuit board 2, any two adjacent reserved interfaces 21 are not connected, so that adjacent character keys 1 will not interfere with each other, and accidental touches and conflicts between character keys 1 can be avoided.

[0041] In one embodiment, if Figure 6 As shown, the input device also includes a limit unit 3, which is arranged on the circuit board 2, and the limit unit 3 corresponds to between any two adjacent reserved interfaces 21. The limit unit 3 can be embedded in the circuit board 2, or bonded to the circuit board 2 using hot melt adhesive, or fixed to the circuit board 2 by mechanical means, and the present disclosure does not limit this. By setting the limit unit 3, a clear area division can be formed on the circuit board 2, so that different functional modules or circuit areas can be clearly distinguished. This not only facilitates visual identification during the manufacturing process, but also helps to quickly locate specific areas during subsequent maintenance and inspection. In addition, during the assembly process of the character key 1, the limit unit 3 can provide an accurate installation position reference for the character key 1 or other components. By aligning the component with the limit unit 3, it can be ensured that the component is placed accurately, avoiding circuit failures or performance problems caused by improper installation positions.

[0042] An embodiment of the present disclosure further provides an electronic device, including the above-mentioned input device. The input device and the electronic device may be independently provided or integrally provided. For example, the electronic device is a laptop computer, and the input device (keyboard) is directly provided on the C surface of the laptop computer. The input device of the present disclosure may also be independent and connected to the electronic device via Bluetooth, wired mode, etc.

[0043] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved, and this document does not limit this.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
