隨著科技的進步與發展，市面上有多種電子裝置都採用觸控面板（touch panel）或觸控板（touch pad）作為操作介面，使用者通常以手指在觸控面板上操作，但是用手指在觸控面板上滑動時因手指接觸面積較廣而容易造成摩擦力太大，不適合大量或快速輸入，同時也可能發生誤觸的情形，因此便有觸控筆問世。With the advancement and development of science and technology, various electronic devices on the market use touch panels or touch pads as the operation interface. Users usually operate on the touch panel with their fingers, but with their fingers When sliding on the touch panel, due to the wide contact area of the finger, it is easy to cause too much friction, which is not suitable for a large amount of or fast input, and may also cause accidental touches, so the stylus has come out.

既有的觸控筆可分為主動式與被動式，其中主動式觸控筆是由筆內的訊號發射電路發送訊號，而使相應的觸控面板（或觸控板）收到訊號後判斷其被接觸位置的座標以及觸壓力。也就是說，主動式觸控筆是通過筆芯受驅動（書寫）時，將筆芯所受的壓力傳送至壓力感測器以產生觸壓力的感測訊號。Existing stylus can be divided into active and passive stylus. The active stylus sends a signal from the signal transmitting circuit inside the pen, so that the corresponding touch panel (or touch panel) can judge its status after receiving the signal. The coordinates of the touched position and the touch force. That is to say, when the active stylus is driven (writing) through the pen core, the pressure on the pen core is transmitted to the pressure sensor to generate a sensing signal of the touch pressure.

The distance D1 is maintained between the first pad 121b on the lower surface S4 and the first pad 121a and the second pad 122a corresponding to each other (the same is true for the first pad 121b and the second pad 122b, which are omitted here) , and the first pads 121a, 121b and the second pads 122a, 122b are connected to each other in a one-to-one correspondence through the soldering material 160 (take one of the first pads 121a and one of the second pads 122a as an example).

基於上述構件配置，電路板模組120的第一電路板121與第二電路板122、壓力感測器130的銲接面S2、電性導通路徑L2與感壓面S1，以及筆芯模組140的抵接件141、固持件142與筆芯143即能形成導通電路，進而讓第一電路板121所產生的TX訊號能順利地以上述導通電路傳送至筆芯143。Based on the above component configuration, the first circuit board 121 and the second circuit board 122 of the circuit board module 120, the welding surface S2 of the pressure sensor 130, the electrical conduction path L2 and the pressure sensing surface S1, and the refill module 140 The abutting part 141 , the holding part 142 and the refill 143 can form a conduction circuit, so that the TX signal generated by the first circuit board 121 can be smoothly transmitted to the refill 143 through the conduction circuit.

舉例來說，當使用者在操作主動式觸控筆100時，筆芯模組140的筆芯143會隨著不同的書寫姿態、筆跡，而承受不同程度的壓力，經由固持件142與抵接件141而直接反應（傳送）至壓力感測器130。第一電路板121上的運算處理單元接收壓力感測器130傳遞來的電訊號，而據以計算出筆尖壓力大小，並轉換成對應的壓力階數。之後，再將不同的壓力階數轉換為不同的頻率或數位信號，並經第一電路板121上的變壓單元（未繪示）將上述頻率或信號轉換為筆芯模組140所需的電壓（訊號），依序經由上述導通電路而傳送至筆芯143，以利於發送至觸控面板（或觸控板），而形成對應的筆跡。換句話說，本實施例用以傳送TX訊號的導通電路實質上與筆芯模組140至壓力感測器130的力傳遞軸向相同且方向相反，且明顯地毋須另行設置其他專用的電訊號傳送構件，其中力感測方向實質上是以負Y軸方向行進，而TX訊號則是以正Y軸方向行進。For example, when the user is operating the active stylus 100, the refill 143 of the refill module 140 will bear different degrees of pressure according to different writing postures and handwritings. The element 141 directly responds (transmits) to the pressure sensor 130 . The arithmetic processing unit on the first circuit board 121 receives the electrical signal from the pressure sensor 130 to calculate the pressure of the pen tip and convert it into a corresponding pressure level. Afterwards, the different pressure steps are converted into different frequencies or digital signals, and the above-mentioned frequencies or signals are converted into the required signals by the refill module 140 through the voltage transformation unit (not shown) on the first circuit board 121. The voltage (signal) is transmitted to the refill 143 through the above-mentioned conduction circuit in sequence, so as to facilitate sending to the touch panel (or touch panel) to form corresponding handwriting. In other words, the conduction circuit used to transmit the TX signal in this embodiment is substantially the same axial direction and opposite to the force transmission direction from the refill module 140 to the pressure sensor 130, and obviously no other dedicated electrical signals are required. The transmission component, wherein the force sensing direction substantially travels in the negative Y-axis direction, and the TX signal travels in the positive Y-axis direction.

綜上所述，在本發明的上述實施例中，電路板模組包括彼此垂直且電性連接的第一電路板與第二電路板，壓力感測器配置且電性連接於第二電路板，且壓力感測器的感壓面與銲接面之間存在至少一電性導通路徑。筆芯模組包括同（中心）軸設置的筆芯、固持件與抵接件，且皆具有導電性，其中抵接件抵接於感壓面上。據此，上述構件形成導通電路，而用以將第一電路板所產生的TX訊號經由所述導通電路傳送至筆芯。此舉讓壓力感測器成為主動式觸控筆用以傳送訊號的媒介，據以省略額外的訊號傳送構件，因此能有效節省主動式觸控筆的內部空間且縮短訊號傳送路徑而達到提高傳感效率的目的。To sum up, in the above embodiments of the present invention, the circuit board module includes a first circuit board and a second circuit board that are perpendicular to each other and are electrically connected, and the pressure sensor is configured and electrically connected to the second circuit board , and there is at least one electrical conduction path between the pressure sensing surface and the welding surface of the pressure sensor. The refill module includes a refill arranged on the same (central) axis, a holder and an abutment, all of which have electrical conductivity, wherein the abutment abuts on the pressure-sensitive surface. Accordingly, the above-mentioned components form a conduction circuit for transmitting the TX signal generated by the first circuit board to the pen cartridge through the conduction circuit. This makes the pressure sensor a medium for the active stylus to transmit signals, thereby eliminating additional signal transmission components, thus effectively saving the internal space of the active stylus and shortening the signal transmission path to achieve improved transmission. purpose of efficiency.
