Description

一种机械式按键和应用其的键盘及键盘组装方法Mechanical button and keyboard and keyboard assembly method using same 技术领域Technical field
本发明属于电子命令输入设备的按键的技术领域，尤其涉及机械式按键和键盘及其组装方法。  The invention belongs to the technical field of buttons of an electronic command input device, in particular to a mechanical button and a keyboard and an assembly method thereof.
背景技术Background technique
目前，计算机用键盘多采用单体按键开关组合结构，单体按键通常由键帽、推杆、硅胶弹件及薄膜电路组成，键帽与推杆一体成形，硅胶弹件设于推杆下方，所述的薄膜电路设于所述的硅胶弹件下方，使用时，通过按压键帽，带动推杆下压，然后，通过硅胶弹件下压到薄膜电路上，使薄膜电路导通，从而起到输入的效果，放开键帽，在硅胶弹件的弹力作用下，推杆向上，使薄膜电路断开。这种结构的按键，其只有两个状态，一个是断开，一个是导通，推杆在其导通后，没有再往下的行程。若将这种结构的按键应用在游戏键盘时，其具有以下缺点：一，游戏者的手感较差；二，灵敏度不高；三，速度慢At present, the keyboard for the computer mostly adopts a single button switch combination structure, and the single button is usually composed of a key cap, a push rod, a silicone elastic member and a film circuit, and the key cap and the push rod are integrally formed, and the silicone elastic member is arranged under the push rod. The thin film circuit is disposed under the silicone elastic member, and when used, the push rod is pressed by pressing the key cap, and then pressed onto the thin film circuit by the silicone elastic member to turn on the thin film circuit, thereby To the effect of the input, release the keycap, and under the elastic force of the silicone elastic member, the push rod is upward, and the film circuit is disconnected. The button of this structure has only two states, one is open and the other is conductive, and the pusher does not go down after it is turned on. If the button of this structure is applied to the game keyboard, it has the following disadvantages: first, the player's hand feel is poor; second, the sensitivity is not high; third, the speed is slow
现有的另外一种游戏专用键盘，其在导通后，还可以有往下走的空行程，采用单颗的轴芯组件然后焊接在PCB板上，每颗轴芯组件内部具有复杂的机械结构，其成本高，价格昂贵，由于轴芯组件、PCB板价格高以及生产工艺导致每只键盘售价高达1000元人民币以上，在行业内得不到广泛推广应用。Another existing game-specific keyboard, after being turned on, can also have an empty stroke going down, using a single core assembly and then soldering on the PCB, each of which has complex machinery inside the core assembly. The structure is high in cost and expensive. Due to the high price of the shaft core component, the PCB board and the production process, the price of each keyboard is more than 1000 yuan, which is not widely used in the industry.
另外申请人公开的另外一件申请中使用重荷弹簧和轻荷弹簧重叠在一个轴线上，触点在导通后轻荷弹簧被限位台阻挡后重荷弹簧可以继续下压，成为空行程，也能够达到机械键盘的手感，但这样的设计存在灵敏度的问题，必须等触点被下压一定距离导通导电膜后然后其轻荷弹簧被继续压缩直到受限位台阻挡后重荷弹簧才开始收缩，所以从键帽下压到导通的时间较长，存在灵敏度差的问题。In another application disclosed by the applicant, the heavy spring and the light spring are overlapped on one axis, and after the contact is blocked, the light spring is blocked by the limit station, and the heavy spring can continue to press down, becoming an idle stroke. It can achieve the feel of the mechanical keyboard, but such design has the problem of sensitivity. It must wait for the contact to be pressed down a certain distance to conduct the conductive film, and then the light-loaded spring is continuously compressed until the heavy-duty spring begins to shrink after the restricted position block is blocked. Therefore, the time from pressing down to the conduction of the key cap is long, and there is a problem of poor sensitivity.
行业内在追求机械键盘的手感速度等技术指标时，急需一种具有薄膜电路般低成本的电路载体和相对于单颗轴芯组件成本低廉的新型轴芯组件来降低整体机械键盘的市场价格，使灵敏度高手感好的机械键盘得以早日普及。In the industry, when pursuing technical indicators such as the feel speed of a mechanical keyboard, there is an urgent need for a circuit carrier having a low cost as a thin film circuit and a novel axial core assembly having a low cost relative to a single axial core assembly to reduce the market price of the overall mechanical keyboard. A mechanical keyboard with a high sensitivity and good hand feels popular.

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
实施例一，参照图1-3所示，本实施例提供一种机械式按键，包括键帽10，轴芯40，外壳30，下盖21，所述键帽10装配于所述轴芯40上方，所述外壳30包围在所述轴芯40周围并对所述轴芯40进行限位，所述下盖21设于所述轴芯40下方，所述下盖21上方铺设有微动感应片70，所述微动感应片70上方设有弹性件，所述弹性件采用上细下粗的喇叭状弹簧50，所述弹簧50上方与所述轴芯40连接，所述微动感应片70上方设有定位板60，所述定位板60设有可供所述弹簧穿越的定位孔，所述外壳30的下端抵压所述定位板60。依借上述技术方案，通过采用微动感应片70来进行传递按键动作信号，而微动感应片70是通过下压部件对电容负荷产生的微动而发送信号的，也就是说在微动感应片70感受到下压部件（弹性件）的下压初始阶段即可以产生变量，将其产生变量作为一个命令向外发送，而下压部件的继续下压时的变量则不予考虑，给所述弹性件（弹簧50）带来了继续下压运行的空间，这样既可以达到机械按键的手感效果，同时灵敏度也会达到所需要求，而在弹簧50与微动感应片70之间需要设置一个对所述弹簧50限位的组件，同时也需要保证所述弹簧50在下压过程中是完全垂直下压不会偏转，故此，所述定位板60上所设置的定位孔将所述弹簧50下部边缘限位在其内，而所述弹簧的底部坐在所述微动感应片70具有电容感应的相对位置。The first embodiment, as shown in FIG. 1-3, provides a mechanical button, including a keycap 10, a core 40, a casing 30, and a lower cover 21. The keycap 10 is mounted on the core 40. Upper, the outer casing 30 surrounds the axial core 40 and limits the axial core 40. The lower cover 21 is disposed under the axial core 40, and the lower cover 21 is provided with a micro-motion sensing. The sheet 70 is provided with an elastic member above the micro-motion sensing sheet 70, and the elastic member is a bell-shaped spring 50 which is thick and thick, and the spring 50 is connected to the shaft core 40, and the micro-motion sensing sheet is connected. A positioning plate 60 is disposed above the positioning plate 60. The positioning plate 60 is provided with a positioning hole through which the spring passes, and the lower end of the outer casing 30 presses against the positioning plate 60. According to the above technical solution, the key motion signal is transmitted by using the micro-motion sensor 70, and the micro-motion sensor 70 transmits a signal by the micro-motion generated by the pressing component to the capacitive load, that is, in the micro-motion sensing. The sheet 70 senses that the initial stage of depression of the pressing member (elastic member) can generate a variable, and the generated variable is sent out as a command, and the variable when the pressing member continues to be depressed is not considered. The elastic member (spring 50) brings about a space for continuing the pressing operation, so that the hand feeling effect of the mechanical button can be achieved, and the sensitivity can also meet the required requirements, and the spring 50 and the jog sensor 70 need to be set. An assembly for limiting the spring 50 also needs to ensure that the spring 50 is completely vertically depressed during the pressing process and does not deflect. Therefore, the positioning hole provided on the positioning plate 60 places the spring 50. The lower edge is constrained therein, and the bottom of the spring sits at a relative position of the micro-motion sensing plate 70 that is capacitively sensed.
所述弹簧50的底位于所述定位孔中，所述弹簧50的顶部套接在所述轴芯40下方的凹槽内，喇叭状弹簧也叫塔形弹簧，是为了力上下运行时始终保持在一条垂直线上而不出现偏移，为了固定所述喇叭状弹簧50，将其底部置入在所述定位孔中，所述定位孔对所述弹簧50起到定位作用，因为所述定位孔是上下通孔，所以所述弹簧50底部实际与所述微动感应片70接触，当受到自所述键帽10向下施加的力后，所述轴芯40压迫所述弹簧50的上端，然后所述弹簧50收缩，在收缩的同时，所述弹簧50底部得到压力触发所述微动感应片70将信号发出。The bottom of the spring 50 is located in the positioning hole, the top of the spring 50 is sleeved in the groove below the core 40, and the horn spring is also called a tower spring, which is always maintained for the force to run up and down. In the absence of an offset on a vertical line, in order to fix the horn spring 50, the bottom is placed in the locating hole, the locating hole locating the spring 50 because of the positioning The hole is an upper and lower through hole, so that the bottom of the spring 50 is actually in contact with the jog sensor 70, and the core 40 presses the upper end of the spring 50 when subjected to a force applied downward from the keycap 10. Then, the spring 50 is contracted, and at the same time as the contraction, the bottom of the spring 50 is pressurized to trigger the micro-motion sensing sheet 70 to emit a signal.
所述下盖21与所述微动感应片70之间设有导光板80，所述导光板80的侧面具有向所述导光板80截面内照射的LED光源，所述导光板80下表面与所述轴芯40相对应的位置设有可向上反光的凹面，所述轴芯40采用透明材质，所述键帽10上所标示的字符具有透光性。所述导光板80侧边设有LED光源，为了能够更好的集中光线向上，在所述导光板80下方设反光膜，键盘在工作时，LED光源发光，将光线照射到所述导光板80的侧边截面上，所述导光板80将光线向上下折射，所述反光膜将向下折射的光线向上反射，由于所述微动感应片70及定位板60、轴芯40外壳30均采用可透光的材质，光线继续向上通过键帽10的漏光键标射出，这样的结构设计致使光线经过折射和反射后射出更加柔和，对使用者的眼睛不会造成刺激。A light guide plate 80 is disposed between the lower cover 21 and the micro-motion sensing sheet 70. The side surface of the light guide plate 80 has an LED light source that is irradiated into the cross section of the light guide plate 80. The lower surface of the light guide plate 80 is The corresponding position of the shaft core 40 is provided with a concave surface that can be reflected upward. The shaft core 40 is made of a transparent material, and the characters indicated on the keycap 10 are translucent. An LED light source is disposed on a side of the light guide plate 80. In order to better concentrate the light upward, a reflective film is disposed under the light guide plate 80. When the keyboard is in operation, the LED light source emits light, and the light is irradiated to the light guide plate 80. The light guide plate 80 refracts the light upward and downward, and the light reflecting film reflects the downwardly refracted light upward, because the micro motion sensing sheet 70 and the positioning plate 60 and the outer shell 30 of the shaft core 40 are used. The light-transmissive material continues to pass upward through the light leakage key of the keycap 10. This structural design causes the light to be refracted and reflected to be softer and does not cause irritation to the user's eyes.
为了能够使光线分布均匀，所述导光板80具有多个可向上反光的凹面，光线经过所述凹面后产生反射和折射，使整个导光板80所发出的光线均匀，通过键帽10的漏光键标显示出来的光亮一致。In order to make the light distribution uniform, the light guide plate 80 has a plurality of concave surfaces that can be reflected upward, and the light passes through the concave surface to generate reflection and refraction, so that the light emitted by the entire light guide plate 80 is uniform, and the light leakage key passing through the key cap 10 is passed. The light displayed by the label is consistent.
为了便于生产，本实施例优选方案是，所述导光板80由至少两片组合而成，按所需形状，将所述导光板80分为多块制造，然后将其拼接为整块导光板80，导光板分开多块进行制造，然后拼装到键盘内，可以大大降低导光板的生产成本。In order to facilitate the production, in the preferred embodiment, the light guide plate 80 is composed of at least two pieces, and the light guide plate 80 is divided into a plurality of pieces according to a desired shape, and then spliced into a whole light guide plate. 80, the light guide plate is manufactured separately from multiple pieces, and then assembled into the keyboard, which can greatly reduce the production cost of the light guide plate.
为了让按键本身提升质量及稳定性，所述导光板80与下盖21之间设有加重板90。In order to improve the quality and stability of the button itself, a weight plate 90 is disposed between the light guide plate 80 and the lower cover 21.
