本发明是关于一种触控笔，特别是一种适用于光感应触控技术的触控笔。The invention relates to a stylus, in particular to a stylus suitable for light-sensing touch technology.
【背景技术】【Background technique】
请参照图1，系为现有的光感应式触控笔100的笔头端110示意图。于光感应式触控笔100的笔头端110设有一容室120，以容置发光元件130、磁性移动件140及磁性固定件150。发光元件130与磁性移动件140固定连接。磁性移动件140与磁性固定件150具有相同磁极，并设置于两者间磁力有效范围内，使得发光元件130因磁性移动件140与磁性固定件150间的相斥磁力而保持凸出于笔头端110外。此时，发光元件130与供电线路（图未示）断路而不发光。Please refer to FIG. 1 , which is a schematic diagram of a tip end 110 of a conventional light-sensing stylus 100 . A chamber 120 is provided at the nib end 110 of the light-sensing stylus 100 for accommodating the light emitting element 130 , the magnetic moving part 140 and the magnetic fixing part 150 . The light emitting element 130 is fixedly connected with the magnetic moving part 140 . The magnetic moving part 140 and the magnetic fixing part 150 have the same magnetic pole, and are arranged within the effective range of the magnetic force between the two, so that the light-emitting element 130 remains protruding from the end of the pen due to the repulsive magnetic force between the magnetic moving part 140 and the magnetic fixing part 150 110 outside. At this time, the light emitting element 130 is disconnected from the power supply line (not shown in the figure) and does not emit light.
当以光感应式触控笔100对如触控面板、触控板或电子白板等触控装置（图未示）进行触控输入时，发光元件130抵顶触控装置而向容室120内部位移，带动磁性移动件140向磁性固定件150位移。此时，发光元件130电连接供电线路（图未示）而发光。When the light-sensitive stylus 100 is used to perform touch input on a touch device (not shown) such as a touch panel, a touchpad, or an electronic whiteboard, the light-emitting element 130 pushes against the touch device and enters the chamber 120. The displacement drives the magnetic moving part 140 to move toward the magnetic fixing part 150 . At this time, the light emitting element 130 is electrically connected to a power supply line (not shown in the figure) to emit light.
也就是说，欲使发光元件130电连接供电线路，必须对发光元件130施予外力，以克服磁性移动件140与磁性固定件150间的相斥磁力。但由于相斥磁力的作用，将导致使用者须持续输出大于可克服相斥磁力的力量。若无法持续输出一定力量，将导致发光元件130无法连续发光，而造成触控装置感应到的触控信号不连续。That is to say, to make the light-emitting element 130 electrically connected to the power supply line, an external force must be applied to the light-emitting element 130 to overcome the repulsive magnetic force between the magnetic moving part 140 and the magnetic fixing part 150 . However, due to the effect of the repulsive magnetic force, the user must continue to output a force greater than that which can overcome the repulsive magnetic force. If a certain force cannot be continuously output, the light-emitting element 130 will not be able to continuously emit light, and the touch signal sensed by the touch device will be discontinuous.
再者，在遭遇反向作用力时，使用者输出的力量通常是逐步增加的，导致克服相斥磁力需耗费一定期间，使得使用者无法即时于施予触控动作时，察觉触控装置因感应到发光元件130而进行对应动作。Furthermore, when encountering the reverse force, the force output by the user is usually gradually increased, so that it takes a certain period of time to overcome the repulsive magnetic force, so that the user cannot immediately feel the touch device due to the touch action. The light-emitting element 130 is sensed and a corresponding action is performed.
又，以光感应式触控笔100在触控装置上进行触控输入时，不但要控制触碰位置，还要保持一定的输出力量，因此在操作上容易引起触碰位置不准确的问题。In addition, when using the light-sensitive stylus 100 to perform touch input on the touch device, not only the touch position must be controlled, but also a certain output force must be maintained, so the problem of inaccurate touch position is likely to occur in operation.
【发明内容】【Content of invention】
鉴于以上的问题，本发明在于提供一种触控笔，藉以解决先前技术所存在以磁性元件致使发光元件复位所带来的反应时间迟缓、操作不准确等问题。In view of the above problems, the present invention provides a stylus to solve the problems of slow response time and inaccurate operation caused by resetting the light-emitting elements caused by magnetic elements in the prior art.
本发明的一实施例提供一种触控笔，包含壳体及接触感应模块。An embodiment of the invention provides a stylus, including a housing and a touch sensing module.
壳体包含容置空间、开口及笔头内壁。容置空间包含顶端及相对的底端。开口位于容置空间的顶端。笔头内壁自开口延伸并包围容置空间。The casing includes an accommodating space, an opening and an inner wall of the nib. The accommodating space includes a top and a relative bottom. The opening is located at the top of the containing space. The inner wall of the nib extends from the opening and surrounds the accommodating space.
接触感应模块设置于壳体的容置空间，包含移动件、弹性件、发光元件及光感测器。移动件包含彼此连接的透光层及阻光层。弹性件设置于移动件与容置空间的底端之间，其中阻光层位于相邻弹性件的一侧。发光元件设置于移动件的透光层上，以于被启动时朝远离透光层的方向发光。The touch sensing module is arranged in the accommodating space of the casing, and includes a moving part, an elastic part, a light emitting element and a light sensor. The moving part includes a light-transmitting layer and a light-blocking layer connected to each other. The elastic piece is arranged between the moving piece and the bottom end of the accommodating space, wherein the light blocking layer is located on one side of the adjacent elastic piece. The light-emitting element is arranged on the light-transmitting layer of the moving part, so as to emit light in a direction away from the light-transmitting layer when activated.
光感测器设置于壳体的笔头内壁上。于第一状态下，弹性件受一外力而压缩，使透光层位于光感测器前方，光感测器检测到通过透光层的光信号，而触发发光元件启动。于第二状态下，弹性件向移动件提供推力，使阻光层位于光感测器前方，而阻断光感测器接收光信号，发光元件关闭。The light sensor is arranged on the inner wall of the pen head of the casing. In the first state, the elastic member is compressed by an external force, so that the light-transmitting layer is located in front of the light sensor. The light sensor detects the light signal passing through the light-transmitting layer, and triggers the light-emitting element to start. In the second state, the elastic member provides thrust to the moving member, so that the light-blocking layer is located in front of the light sensor, thereby blocking the light sensor from receiving light signals, and the light-emitting element is turned off.
根据本发明的适用于光感应触控技术的触控笔可根据移动件遮断光信号与否判断触控笔是否正在执行触控输入动作，进而致使发光元件发光，可改善先前技术所述利用磁性元件的缺点，并具有反应时间快速、出光稳定性高、操作顺畅等优点。According to the stylus suitable for the light-sensing touch technology of the present invention, it can judge whether the stylus is performing a touch input action according to whether the moving part blocks the light signal, and then causes the light-emitting element to emit light, which can improve the use of magnetism in the prior art. The shortcomings of components, and has the advantages of fast response time, high light stability, smooth operation and so on.

图2为根据本发明第一实施例的触控笔200的立体示意图。图3为根据本发明第一实施例的触控笔200的笔头端210的示意图（即沿图2的A-A线的剖面图）。FIG. 2 is a perspective view of a stylus 200 according to a first embodiment of the present invention. FIG. 3 is a schematic diagram of the tip end 210 of the stylus 200 according to the first embodiment of the present invention (ie, a cross-sectional view along line A-A of FIG. 2 ).
合并参照图2及图3，图中绘示适用于光感应触控技术的触控笔200，该触控笔200包含壳体220及接触感应模块230。壳体220包含容置空间221、容置空间222、开口223、笔头内壁224及笔体内壁225。Referring to FIG. 2 and FIG. 3 , a stylus 200 suitable for light-sensing touch technology is shown in the figure, and the stylus 200 includes a housing 220 and a touch sensing module 230 . The casing 220 includes an accommodating space 221 , an accommodating space 222 , an opening 223 , an inner wall 224 of the pen tip, and an inner wall 225 of the pen tip.
容置空间221包含顶端2211及相对的底端2212。开口223位于容置空间221的顶端。笔头内壁224自开口223延伸并包围容置空间221。也就是说，开口223位于触控笔200的笔头端210的顶部，并由笔头端210的笔头内壁224形成容置空间221以容纳接触感应模块230。The accommodating space 221 includes a top end 2211 and a bottom end 2212 opposite. The opening 223 is located at the top of the receiving space 221 . The nib inner wall 224 extends from the opening 223 and surrounds the accommodating space 221 . That is to say, the opening 223 is located at the top of the nib end 210 of the stylus 200 , and the inner wall 224 of the nib end 210 forms an accommodating space 221 for accommodating the touch sensing module 230 .
于此，笔头内壁224可包含顶壁部2241、侧壁部2242及底壁部2243。顶壁部2241与底壁部2243相对设置，侧壁部2242介于顶壁部2241与底壁部2243之间，并与顶壁部2241的边缘及底壁部2243的边缘相接，藉以由顶壁部2241、侧壁部2242与底壁部2243共同形成容置空间221。Here, the tip inner wall 224 may include a top wall portion 2241 , a side wall portion 2242 and a bottom wall portion 2243 . The top wall portion 2241 is opposite to the bottom wall portion 2243, and the side wall portion 2242 is interposed between the top wall portion 2241 and the bottom wall portion 2243, and is in contact with the edge of the top wall portion 2241 and the edge of the bottom wall portion 2243, thereby The top wall portion 2241 , the side wall portion 2242 and the bottom wall portion 2243 jointly form the accommodating space 221 .
在一些实施例中，顶壁部2241、侧壁部2242及底壁部2243为一体成型。In some embodiments, the top wall portion 2241 , the side wall portion 2242 and the bottom wall portion 2243 are integrally formed.

For example, the bottom wall part 2243 can be a piece, and the side wall part 2242 can have an annular groove for fitting and fixing the bottom wall part 2243 .
如图3所示，接触感应模块230设置于壳体220的容置空间221。接触感应模块230包含移动件231、弹性件232、发光元件233及光感测器234。在本实施例中，弹性件232系以弹簧为例，但本发明非以此为限，弹性件232亦可为弹性薄板（即弹片）等可受外力压缩形变而后又可恢复原状者。As shown in FIG. 3 , the contact sensing module 230 is disposed in the accommodating space 221 of the casing 220 . The touch sensing module 230 includes a moving part 231 , an elastic part 232 , a light emitting element 233 and a light sensor 234 . In this embodiment, the elastic member 232 is a spring as an example, but the present invention is not limited thereto. The elastic member 232 can also be an elastic thin plate (ie, a shrapnel) that can be compressed and deformed by an external force and then return to its original shape.
移动件231包含彼此连接的透光层2311及阻光层2312。弹性件232设置于移动件231与容置空间221的底端2212之间，其中阻光层2312位于相邻弹性件232的一侧。发光元件233设置于移动件231的透光层2311上，以于被启动时朝远离透光层2311的方向发光。也就是说，发光元件233、透光层2311、阻光层2312及弹性件232依序沿开口223朝向容置空间221的底端2212的方向（即弹性件232的压缩方向）连接设置，并于弹性件232的末端固定连接于容置空间221的底端2212。于此，弹性件232可以黏接、锁接、卡扣连接等方式固定连接于底壁部2243（即容置空间221的底端2212）。The moving element 231 includes a transparent layer 2311 and a light blocking layer 2312 connected to each other. The elastic member 232 is disposed between the moving member 231 and the bottom end 2212 of the accommodating space 221 , wherein the light blocking layer 2312 is located on one side of the adjacent elastic member 232 . The light emitting element 233 is disposed on the transparent layer 2311 of the moving member 231 to emit light in a direction away from the transparent layer 2311 when activated. That is to say, the light-emitting element 233 , the light-transmitting layer 2311 , the light-blocking layer 2312 and the elastic member 232 are arranged sequentially along the direction from the opening 223 toward the bottom end 2212 of the accommodating space 221 (that is, the compression direction of the elastic member 232 ), and The end of the elastic member 232 is fixedly connected to the bottom end 2212 of the accommodating space 221 . Here, the elastic member 232 can be fixedly connected to the bottom wall portion 2243 (ie, the bottom end 2212 of the accommodating space 221 ) by means of adhesion, locking, snap connection and the like.
在本实施例中，如图2所示，开口223的形状为圆形，但本发明的实施例并非以此为限，亦可为其他几何图形或可配合发光元件233的外形。In this embodiment, as shown in FIG. 2 , the shape of the opening 223 is circular, but the embodiment of the present invention is not limited thereto, and may also be other geometric figures or shapes that can match the shape of the light emitting element 233 .
图4为根据本发明第一实施例的触发发光元件233启动的示意图（即沿图2的A-A线的剖面图）。FIG. 4 is a schematic diagram (ie, a cross-sectional view along line A-A of FIG. 2 ) of triggering the light-emitting element 233 according to the first embodiment of the present invention.
合并参照图3及图4。光感测器234设置于壳体220的笔头内壁224上，意即光感测器234设置于笔头内壁224的侧壁部2242上。于第一状态下，如图4所示，弹性件232受一外力而压缩，使透光层2311位于光感测器234前方，此时光感测器234检测到通过透光层2311的光信号L，而触发发光元件233启动而发光。于第二状态下，前述的外力消失（或减弱），如图3所示，弹性件232向移动件231提供的推力使发光元件233凸伸于开口223，并使阻光层2312位于光感测器234前方，而阻断光感测器234接收光信号L，此时发光元件233关闭而不发光。藉此，可通过发光元件233是否因触控笔200抵顶前述的触控装置而向内位移，作为是否致使发光元件233发光的依据。Refer to FIG. 3 and FIG. 4 together. The light sensor 234 is disposed on the pen head inner wall 224 of the housing 220 , that is, the light sensor 234 is disposed on the side wall portion 2242 of the pen head inner wall 224 . In the first state, as shown in FIG. 4 , the elastic member 232 is compressed by an external force, so that the light-transmitting layer 2311 is located in front of the light sensor 234. At this time, the light sensor 234 detects the light signal passing through the light-transmitting layer 2311 L, and trigger the light-emitting element 233 to start to emit light. In the second state, the above-mentioned external force disappears (or weakens). As shown in FIG. The front of the detector 234 is blocked, and the light sensor 234 is blocked from receiving the light signal L. At this time, the light emitting element 233 is turned off and does not emit light. In this way, whether the light emitting element 233 is displaced inward due to the stylus 200 abutting against the aforementioned touch device can be used as a basis for causing the light emitting element 233 to emit light.
于此，发光元件233可为发光二极管、激光二极管等可控制发光与否的发光元件。如图3所示，发光元件233为一发光二极管，具有发光二极管芯片2331及包围发光二极管芯片2331的透光层2332。Here, the light emitting element 233 can be a light emitting element such as a light emitting diode, a laser diode, etc., which can be controlled to emit light or not.

The control circuit 240 includes a trigger switch 241 and a power source 242 . The trigger switch 241 includes a first end 2411 , a second end 2412 and a control end 2413 . The first end 2411 is electrically connected to the power source 242 . The second end 2412 is electrically connected to the light emitting element 233 . The control terminal 2413 is electrically connected to the light sensor 234 for receiving the electrical signal S generated by the light sensor 234 according to the received light signal L. The trigger switch 241 makes the first terminal 2411 and the second The two terminals 2412 are turned on, so that the light-emitting element 233 receives power from the power source 242 to activate.
在一些实施例中，光感测器234与触发开关241之间还连接有放大单元243，用以放大电信号S，并输出至触发开关241，以使电信号S可放大至符合触发开关241可检测到的电压值。于此，放大单元243，举例而言，可为运算放大器。In some embodiments, an amplifying unit 243 is connected between the light sensor 234 and the trigger switch 241 to amplify the electrical signal S and output it to the trigger switch 241, so that the electrical signal S can be amplified to match the trigger switch 241. Detectable voltage value. Here, the amplifying unit 243 can be, for example, an operational amplifier.
在一些实施例中，电源242可置放于由笔体内壁225所构成的容置空间222中。并且，笔头内壁224的底壁部2243可具有至少一开孔，以供连接于电源242与发光元件233之间的导电线路穿过底壁部2243。In some embodiments, the power supply 242 can be placed in the accommodating space 222 formed by the inner wall 225 of the pen. Moreover, the bottom wall portion 2243 of the pen head inner wall 224 may have at least one opening for the conductive circuit connected between the power supply 242 and the light emitting element 233 to pass through the bottom wall portion 2243 .
于此，电源242可为锌锰电池、碱锰电池、碳锌电池、氢氧电池、镍氢电池、锂电池或光伏打电池等，用以对触控笔200内部电子元件（如发光元件233、光源元件235等）提供电力。触发开关241可为由至少一晶体管构成的电子开关元件。Here, the power supply 242 can be a zinc-manganese battery, an alkali-manganese battery, a carbon-zinc battery, a hydrogen-oxygen battery, a nickel-metal hydride battery, a lithium battery, or a photovoltaic battery, etc., and is used to control the internal electronic components of the stylus 200 (such as the light emitting element 233 , light source element 235, etc.) to provide power. The trigger switch 241 can be an electronic switch element composed of at least one transistor.

The magnitude of (that is, the optical signal L'). The light emitting element 233 outputs a corresponding amount of light according to the magnitude of the light signal L' detected by the light sensor 234. When the force of the stylus 200 against the touch device is small, the inward displacement of the moving part 231 is small, so that the light signal L is directed to the position where the optical filter 236 has a low light transmittance, and the light sensor 234 receives The received light signal L' is smaller. Conversely, when the force of the stylus 200 against the touch device is greater, the moving part 231 is displaced inwardly by a greater amount, so that the light signal L is directed to the position where the optical filter 236 has greater light transmittance, and the light sensing The optical signal L' received by the device 234 is larger. In this way, when the light emitted by the light-emitting element 233 changes with the light signal L′ received by the light sensor 234, the touch device can receive the amount of light emitted by the stylus 200 that changes with the user's effort. Furthermore, the touch device can display changes in the strength of the brush strokes in visual or auditory ways.
