随着游戏的流行，人们对键盘的要求也普遍提高。键盘的每一颗按键的闭合都是由一个单独的光电机械开关来控制。键盘的光电机械开关主要为光电式光电机械开关。光电式光电机械开关为一个光接收元件接收一个光发射元件发出的信号，键盘立即输出一个执行动作，画面立即显示执行的动作。然而，画面不能显示一个渐近、连贯性地加速执行的过程，导致用户体验的真实感较差。With the popularity of games, people's requirements for keyboards have generally increased. The closing of each key of the keyboard is controlled by a separate opto-mechanical switch. The photoelectric mechanical switch of the keyboard is mainly a photoelectric photoelectric mechanical switch. The photoelectric photoelectric mechanical switch receives a signal from a light emitting element for a light receiving element, and the keyboard immediately outputs an execution action, and the screen immediately displays the performed action. However, the picture cannot show an asymptotically and coherently accelerated process, resulting in a less realistic user experience.

本发明技术方案通过设置至少两个光接收元件，使得PCB板的芯片可根据光接收元件的数量将原始的一个执行信号进行分级成多个信号，通过多个信号依次执行同一命令，故这样就使得执行命令的过程是一种渐进加速的过程，以带来一种渐进连贯的画面效果，更具真实感，更符合消费者的需求。According to the technical solution of the present invention, by providing at least two light receiving elements, the chip of the PCB board can classify the original one execution signal into a plurality of signals according to the number of the light receiving elements, and sequentially execute the same command through the plurality of signals, so that The process of executing the command is a gradual acceleration process to bring about a progressive and coherent picture effect, which is more realistic and more in line with the needs of consumers.
其中，该光电机械开关有两种模式，第一种模式为常闭模式，即初始状态为光路处于断开状态，通过按压轴芯，光路依次导通实现信号的键入；第二种模式为常开模式，即初始状态为光路处于导通状态，通过按压轴芯，光路依次断开，实现信号的键入。Wherein, the photoelectric mechanical switch has two modes, the first mode is a normally closed mode, that is, the initial state is that the optical path is in an off state, and by pressing the core, the optical path is sequentially turned on to realize signal input; the second mode is The open mode, that is, the initial state is that the optical path is in an on state, and by pressing the core, the optical path is sequentially turned off to implement signal input.
具体地，第一种模式：初始状态，轴芯阻断该光接收元件和该光发射元件之间的光路传输，光信号不能传输至PCB板；当按下轴芯时，若干光接收元件依次通过通孔均接收光发射元件的发射的光信号，也即当轴芯向下移动一定距离，一光接收元件通过一通孔接收一光发射元件发出的光信号，中央检测器对于接收的光信号做出响应，产生电信号，PCB板70的芯片对电信号进行处理实现键入信号的输出，电脑CPU执行动作的一步，当轴芯再向下移动一定距离，下一个光接收元件也接收光发射元件的发射的光信号，中央检测器进一步对于接收的光信号做出响应，产生电信号，PCB板的芯片对该电信号进行处理实现键入信号进一步地输出，电脑CPU执行该动作的下一步，直至设有的若干光接收元件均导通，最终电脑CPU执行完一个完整的动作，Specifically, the first mode: an initial state, the core block blocks the optical path between the light receiving element and the light emitting element, and the optical signal cannot be transmitted to the PCB board; when the axis is pressed, the plurality of light receiving elements are sequentially Receiving, by the through holes, the emitted light signal of the light emitting element, that is, when the axis moves downward by a certain distance, a light receiving element receives an optical signal emitted by a light emitting element through a through hole, and the central detector receives the optical signal. In response, an electrical signal is generated, and the chip of the PCB board 70 processes the electrical signal to realize the output of the key input signal. The computer CPU performs a step of the action, and when the axis core moves down a certain distance, the next light receiving element also receives the light emission. The optical signal emitted by the component, the central detector further responds to the received optical signal to generate an electrical signal, and the chip of the PCB board processes the electrical signal to further input the input signal, and the computer CPU performs the next step of the action. Until a plurality of light receiving components are turned on, and finally the computer CPU performs a complete action,
第二种模式：同理，相对第一种模式的高电平输出，该第二种模式为低电平输出，也即，初始状态，所有的光接收元件和该光发射元件之间的光路导通，产生的电信号处于高电平状态键入信号不输出，当轴芯向下移动一定距离，中央检测器对断开的光信号做出响应，产生电信号为低电平状态，PCB板70的芯片对该电信号进行处理实现键入信号的输出，该电脑CPU执行动作的一步，当轴芯再向下移动一定距离，中央检测器进一步对于断开的光信号做出响应，再次产生低电平的电信号，PCB板的芯片进一步对该电信号进行处理实现键入信号的再次输出，电脑CPU执行该动作的下一步，直至设有的若干光接收元件均断开，最终电脑CPU执行完一个完整的动作。The second mode: similarly, the high level output of the first mode, the second mode is a low level output, that is, the initial state, the optical path between all the light receiving elements and the light emitting element Turned on, the generated electrical signal is in a high state, the input signal is not output, when the axis moves downward by a certain distance, the central detector responds to the disconnected optical signal, generating an electrical signal to a low state, the PCB board The chip of 70 processes the electrical signal to realize the output of the key input signal. The computer CPU performs a step of the action. When the axis core moves down a certain distance, the central detector further responds to the disconnected optical signal, and generates a low again. The level of the electrical signal, the chip of the PCB board further processes the electrical signal to realize the re-output of the input signal, and the computer CPU performs the next step of the action until the plurality of light receiving components are disconnected, and finally the computer CPU executes A complete action.
综上两种模式，根据本技术方案均能使得画面效果更加逼真，使用户的视觉和触觉可以达到同步，体验感更强。In summary, the two modes can make the picture effect more realistic according to the technical solution, so that the user's vision and touch can be synchronized and the experience is stronger.

参照图1至8，本发明技术方案提出一种光电机械开关100，包括轴芯10、PCB板70、以及设置于所述PCB板70的至少一光发射元件90与至少两个光接收元件80，所述PCB板70开设有让位孔701，所述轴芯10可移动地容纳于所述让位孔701，将所述至少一光发射元件90和所述至少两个光接收元件80分隔于所述轴芯10的两侧，所述轴芯10进一步开设有若干通孔101，所述若干通孔101的长度依次递减，每一通孔101的上端均对齐，光电机械开关100处于初始状态时，所述若干光接收元件110和所述光发射元件90断开，按压轴芯10时，所述若干光接收元件110通过所述通孔101依次与所述光发射元件90导通；或每一通孔101的下端均对齐，光电机械开关100处于初始状态时，所述若干光接收元件110和所述光发射元件90导通，按压轴芯10，所述光接收元件110逐渐与所述通孔101错开，所述光接收元件110依次与所述光发射元件90断开。 Referring to FIGS. 1 through 8, the technical solution of the present invention provides an optoelectronic mechanical switch 100 including a core 10, a PCB board 70, and at least one light emitting element 90 and at least two light receiving elements 80 disposed on the PCB board 70. The PCB board 70 is provided with a accommodating hole 701, and the shaft core 10 is movably received in the accommodating hole 701 to separate the at least one light emitting element 90 and the at least two light receiving elements 80 On the two sides of the shaft core 10, the shaft core 10 is further provided with a plurality of through holes 101, the lengths of the plurality of through holes 101 are successively decreased, the upper ends of each of the through holes 101 are aligned, and the photoelectric mechanical switch 100 is in an initial state. When the plurality of light receiving elements 110 and the light emitting element 90 are disconnected, the plurality of light receiving elements 110 are sequentially turned on with the light emitting elements 90 through the through holes 101; or The lower ends of each of the through holes 101 are aligned, and when the electromechanical switch 100 is in an initial state, the plurality of light receiving elements 110 and the light emitting elements 90 are turned on, pressing the core 10, and the light receiving elements 110 gradually become The through holes 101 are staggered, and the light receiving element 110 Views of the light emitting element 90 is turned off.
本发明技术方案通过设置至少两个光接收元件110，使得PCB板70的芯片可根据光接收元件110的数量将原始的一个执行信号进行分级成多个信号，通过多个信号依次执行同一命令，故这样就使得执行命令的过程是一种渐进加速的过程，以带来一种渐进连贯的画面效果，更具真实感，更符合消费者的需求。The technical solution of the present invention allows at least two light receiving elements 110 to be arranged such that the chip of the PCB board 70 can classify the original one execution signal into a plurality of signals according to the number of the light receiving elements 110, and sequentially execute the same command through a plurality of signals. Therefore, the process of executing the command is a gradual acceleration process, which brings a progressive and coherent picture effect, which is more realistic and more in line with the needs of consumers.
其中，该光电机械开关100有两种模式，参照图4和图5，第一种模式为常闭模式，即初始状态为光路处于断开状态，通过按压轴芯10，光路依次导通实现信号的键入；参照图6和图7，第二种模式为常开模式，即初始状态为光路处于导通状态，通过按压轴芯10，光路依次断开，实现信号的键入。The photoelectric mechanical switch 100 has two modes. Referring to FIG. 4 and FIG. 5, the first mode is a normally closed mode, that is, the initial state is that the optical path is in an off state, and by pressing the core 10, the optical path is sequentially turned on to realize a signal. Referring to FIG. 6 and FIG. 7, the second mode is the normally open mode, that is, the initial state is that the optical path is in an on state, and by pressing the core 10, the optical path is sequentially turned off to realize signal input.
具体地，第一种模式：初始状态，轴芯10阻断该光接收元件110和该光发射元件90之间的光路传输，光信号不能传输至PCB板70；当按下轴芯10时，若干光接收元件110依次通过通孔101均接收光发射元件90的发射的光信号，也即当轴芯10向下移动一定距离，一光接收元件110通过一通孔101接收一光发射元件90发出的光信号，中央检测器对于接收的光信号做出响应，产生电信号，PCB板70的芯片对电信号进行处理实现键入信号的输出，电脑CPU执行动作的一步，当轴芯10再向下移动一定距离，下一个光接收元件110也接收光发射元件90的发射的光信号，中央检测器进一步对于接收的光信号做出响应，产生电信号，PCB板70的芯片对该电信号进行处理实现键入信号进一步地输出，电脑CPU执行该动作的下一步，直至设有的若干光接收元件110均导通，最终电脑CPU执行完一个完整的动作，Specifically, in the first mode: the initial state, the core 10 blocks optical path transmission between the light receiving element 110 and the light emitting element 90, and the optical signal cannot be transmitted to the PCB board 70; when the core 10 is pressed, The plurality of light receiving elements 110 sequentially receive the emitted light signals of the light emitting elements 90 through the through holes 101, that is, when the core 10 moves downward by a certain distance, a light receiving element 110 receives a light emitting element 90 through a through hole 101. The optical signal, the central detector responds to the received optical signal, generates an electrical signal, and the chip of the PCB board 70 processes the electrical signal to realize the output of the input signal, and the computer CPU performs a step of the action, when the core 10 goes down again Moving a certain distance, the next light receiving element 110 also receives the transmitted optical signal of the light emitting element 90, and the central detector further responds to the received optical signal to generate an electrical signal, and the chip of the PCB board 70 processes the electrical signal. The input signal is further outputted, and the computer CPU performs the next step of the action until the plurality of light receiving components 110 are turned on, and finally the computer CPU performs a complete motion. Work,
第二种模式：同理，相对第一种模式的高电平输出，该第二种模式为低电平输出，也即，初始状态，所有的光接收元件110和该光发射元件90之间的光路导通，产生的电信号处于高电平状态键入信号不输出，当轴芯10向下移动一定距离，中央检测器对断开的光信号做出响应，产生电信号为低电平状态，PCB板70的芯片对该电信号进行处理实现键入信号的输出，该电脑CPU执行动作的一步，当轴芯10再向下移动一定距离，中央检测器进一步对于断开的光信号做出响应，再次产生低电平的电信号，PCB板70的芯片进一步对该电信号进行处理实现键入信号的再次输出，电脑CPU执行该动作的下一步，直至设有的若干光接收元件110均断开，最终电脑CPU执行完一个完整的动作。The second mode: similarly, the high level output of the first mode, the second mode is a low level output, that is, the initial state, between all the light receiving elements 110 and the light emitting element 90 The optical path is turned on, the generated electrical signal is in a high state, and the input signal is not output. When the core 10 moves downward by a certain distance, the central detector responds to the disconnected optical signal, and the electrical signal is in a low state. The chip of the PCB board 70 processes the electrical signal to realize the output of the key signal, and the computer CPU performs a step of the action. When the core 10 moves downward by a certain distance, the central detector further responds to the broken optical signal. The low-level electrical signal is generated again, and the chip of the PCB board 70 further processes the electrical signal to realize the re-output of the key-in signal, and the computer CPU performs the next step of the action until the plurality of light-receiving components 110 are disconnected. Finally, the computer CPU performs a complete action.
综上两种模式，根据本技术方案均能使得画面效果更加逼真，使用户的视觉和触觉可以达到同步，体验感更强。In summary, the two modes can make the picture effect more realistic according to the technical solution, so that the user's vision and touch can be synchronized and the experience is stronger.
其中，该光发射元件90可以为LED灯、RGB灯、红外线发射管等，当然可以理解地，凡所有通过光路传输信号的方式均属于本实施例的保护范围，在此不再一一赘述。The light emitting element 90 can be an LED lamp, an RGB lamp, an infrared emitting tube, etc., of course, all the manners of transmitting signals through the optical path are within the protection scope of the embodiment, and are not described herein again.
