Description
本發明係關於一種可減少一筆記型電腦之體積及重量，並增加其使用壽命之筆記型電腦觸控輸入裝置。
The present invention relates to a notebook type touch input device capable of reducing the size and weight of a notebook computer and increasing its service life.
隨著科技資訊不斷的進步，電腦、筆記型電腦及平板型電腦是目前生活或工作中不可或缺的電子裝置之一，而用於輸入指向的鍵盤更是該等電腦不可或缺的硬體周邊裝置之一，用以輸入字元、數字或指令等。
現在許多電腦使用者不僅會注重中央處理單元（CPU）、記憶體、硬碟、顯卡等直接關係電腦性能的硬體裝置，而且也開始對鍵盤和滑鼠等輸入裝置的選擇也開始重視起來，因為許多的電腦使用者逐漸體認到中央處理單元已經發展到效能較為強大，其效能已經足夠能滿足大多數的家用或辦公用的需求，而作為人機互動的媒介，鍵盤和滑鼠等輸入指向裝置才是使用電腦時接觸最多的部件，所以對滑鼠及鍵盤的選擇也是非常重要的。
現有習知筆記型電腦或平板型電腦之鍵盤結構，主要形式係為機械式，其包括複數個按鍵頂蓋、一具有多數依照按鍵位置排列之圓孔的電板，以及一置於電板下方之橡膠片，電板上的每個圓孔邊緣設有一對直徑地向外延伸的限位槽，而每個按鍵頂蓋之底側面上連接有一圓管體以及一對彈性扣鉤；所述圓管體之一端係穿過電板之各圓孔而與該電板之各圓孔同軸地滑動接觸，且同時該對彈性扣鉤則穿過該電板之兩限位槽，令該按鍵頂蓋在與該電板之各圓孔同軸相對滑動時不會向上脫出，橡膠片的上側面凸設有多數相對應電板之圓孔的撓性凸起，該撓性凸起可由於受到各案件頂蓋的圓管體向下之推頂而向下推頂置於橡膠片下方之具電路的導電薄膜，因此得啟動一對應信號，而後該撓性凸起向上將按鍵頂蓋推回原位。
然而現今輕、薄、短、小是筆記型電腦及平板型電腦之設計目標及要求，而其中由於所有電腦各組件的厚度均已至極限無法更薄化的情況下，盡量降低按鍵頂蓋高度，以期能明顯達到縮小按鍵整體厚度，以薄化該筆記型電腦整體厚度；但在筆記型電腦的通用規格要求中，該按鍵頂蓋被向下按壓的位移行程係被限制至少要大於一最小值，該最小值通常為3mm，亦即操作者輸入使用時將其下壓的操作行程(下移位移量)不能小於3mm，此乃人類輸入時手指換鑑的速度必須不能快於鍵盤單一按鍵訊號傳遞的速度，以避免前一訊號尚未傳輸完畢而使操作者的手指已按壓並離開後依按鍵，導致後一訊號與前一訊號重疊而使電腦收不到該後一訊號，因此按鍵被向下的位移量必須保持一最小值；而若是將彈性扣鉤的長度縮短，固然可降低按鍵頂蓋的高度達到縮短操作行程，但如此一來卻使按鍵頂蓋不符產品規格之要求。
為此，即有業者為了輕薄之設計目標捨棄上述習知該機械式按鍵之應用，而將原本應用機械式按鍵的輸入結構採以觸控式輸入裝置，該觸控式裝置係使用電容式觸控方式，其結構由外向內分別是於最外層係為保護層(可為玻璃或壓克力)，其次係為一薄薄的二氧化矽硬化處理層，之後則為銦錫氧化物（ITO）薄膜，並於該玻璃表面建立一均勻電場，利用感應人體微弱電流的方式來達到觸控輸入的目的，雖該觸控式輸入裝置可以有效的大幅薄化該筆記型電腦之整體厚度，但其成本高且易造成其材料容易疲勞，導致使用壽命縮短。
以上所述，習知具有下列之缺點：
1.體積過大且笨重；
2.成本高；
3.壽命較短。
是以，要如何解決上述習用之問題與缺失，即為本案之發明人與從事此行業之相關廠商所亟欲研究改善之方向所在者。
With the continuous advancement of scientific and technological information, computers, notebook computers and tablet computers are one of the indispensable electronic devices in life or work, and the keyboard for input pointing is an indispensable hardware for such computers. One of the peripheral devices for inputting characters, numbers or instructions.
Nowadays, many computer users not only pay attention to the central processing unit (CPU), memory, hard disk, graphics card and other hardware devices directly related to computer performance, but also begin to pay attention to the choice of input devices such as keyboard and mouse. Because many computer users have gradually realized that the central processing unit has developed to be more powerful, its performance is enough to meet most of the needs of home or office use, and as a medium for human-computer interaction, keyboard and mouse input. The pointing device is the most accessible part when using the computer, so the choice of mouse and keyboard is also very important.
The keyboard structure of the conventional notebook computer or tablet computer, the main form is a mechanical type, which comprises a plurality of button top covers, an electric board having a plurality of round holes arranged according to the position of the button, and one placed under the electric board a rubber sheet, each of the round hole edges of the electric plate is provided with a pair of diametrically extending limiting slots, and a bottom tube side of each button top cover is connected with a circular tube body and a pair of elastic clasps; One end of the round pipe body passes through the circular holes of the electric plate and is in sliding contact with the circular holes of the electric plate, and at the same time, the pair of elastic buckles pass through the two limit slots of the electric plate, so that the button The top cover does not detach upward when coaxially sliding with the circular holes of the electric board, and the upper side of the rubber sheet protrudes with a plurality of flexible protrusions corresponding to the circular holes of the electric board, and the flexible protrusion can be The circular tube body of each case is pushed down to push down the conductive film under the rubber sheet, so that a corresponding signal is activated, and then the flexible protrusion pushes the button top cover upward. Return to the original position.
However, today's light, thin, short, and small are the design goals and requirements of notebook computers and tablet computers. In the case where the thickness of all computer components has reached the limit and cannot be thinned, the height of the button top cover is minimized. In order to significantly reduce the overall thickness of the button to thin the overall thickness of the notebook; but in the general specification of the notebook computer, the displacement of the button top cover is limited to at least a minimum Value, the minimum value is usually 3mm, that is, the operation stroke (downward displacement amount) for the operator to press down when using the input cannot be less than 3mm, which is faster than the single keyboard when the human input is used. The speed of the key signal transmission is to prevent the previous signal from being transmitted yet, so that the operator's finger has been pressed and left, and then the button is pressed, so that the latter signal overlaps with the previous signal, so that the computer cannot receive the latter signal, so the button The amount of displacement to be downward must be kept to a minimum; and if the length of the elastic hook is shortened, the height of the top cover of the button can be reduced to shorten the operation line. , But the result does not match the roof while filling key requirements of the product specifications.
For this reason, the manufacturer has abandoned the above-mentioned application of the mechanical button for the slim design goal, and the input structure of the mechanical button is originally adopted as a touch input device, which uses capacitive touch. Control method, the structure is from the outside to the inside, the outermost layer is a protective layer (may be glass or acrylic), followed by a thin thin layer of cerium oxide hardening layer, followed by indium tin oxide (ITO) a film, and a uniform electric field is established on the surface of the glass, and the touch input is achieved by sensing the weak current of the human body. Although the touch input device can effectively thin the overall thickness of the notebook computer, The cost is high and it is easy to cause the material to be easily fatigued, resulting in a shortened service life.
As mentioned above, the conventional disadvantages have the following disadvantages:
1. The volume is too large and cumbersome;
2. High cost;
3. Short life.
Therefore, how to solve the above problems and problems in the past, that is, the inventors of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.
爰此，為有效解決上述之問題，本發明之主要目的在於提供一種可使筆記型電腦之體積厚度大幅薄化且重量較為輕巧之筆記型電腦觸控輸入裝置。

The above object of the present invention, as well as its structural and functional features, will be described in accordance with the preferred embodiments of the drawings.
1A and 1B, and 1C and 1D, which are perspective exploded views and partial enlarged views and partial enlarged views and perspective views of the first embodiment of the notebook computer touch input device of the present invention, as shown in the figure. As shown, a notebook computer touch input device 1 includes a first body 10, a second body 11 and at least one touch module 113. The first body 10 has a display module 101. The display The module 101 is disposed on the first body 10, and the second body 11 is pivotally connected to the first body 10, and the first body 10 is selectively closable relative to the second body 11 or The second body 11 has a main surface 111 opposite to the display module 101;
The touch module 113 is disposed on the main surface 111 and electrically connected to the second body 11. The touch module 113 includes a plurality of transmitters 1131 and a plurality of receivers 1132. The transmitters 1131 are Corresponding to the receivers 1132, and jointly defining a touch space 1133, the second body 11 includes a host module 112, and the host module 112 is electrically connected to the display module 101 and the touch Module 113;
The aforementioned transmitter 1131 optically transmits a signal to the receiver 1132 for reception, and the optical mode transmits a signal to the receiver 1132 for receiving by infrared rays.
Please refer to FIG. 2 , which is a perspective view of the first embodiment of the notebook computer touch input device 1 of the present invention. The touch space 1133 can form a virtual keyboard 1134, and the virtual keyboard 1134 has a virtual keyboard 1134. The virtual button 1135 has different language systems, and the virtual button 1135 includes a plurality of symbol virtual buttons 1135a and a plurality of character virtual buttons 1135b. Therefore, the structure design of the notebook type touch input device 1 of the present invention is adopted. The touch space 1133 is defined by the transmitter 1131 and the receiver 1132. When the user wants to use the notebook, an object (which can be a finger or a pen or other manipulation device) 2 is first touched. The touch module 113 on the main surface 111 of the second body 11 is blocked by the foreign object 2 due to the signal transmitted and received, thereby positioning and recognizing the text or symbol required by the user. The text or symbol is displayed on the display module 101 of the first body 10, which has the disadvantages of improving the traditional mechanical keyboard and causing the notebook computer to be too large and occupying too much space. In addition, the volume of the notebook computer can be greatly thinned and lighter; in addition, since the transmitter 1131 optically transmits signals to the receiver 1132, instead of the conventional touch input device The use of capacitive touch will cause the material to be easily fatigued, which will greatly increase the length of life of the notebook.
3A and 3B are perspective views of a second embodiment of a notebook computer touch input device according to the present invention, and the corresponding components of the notebook computer touch input device and the corresponding relationship between the components It is the same as the aforementioned notebook type touch input device, so it will not be described here. However, the main difference between the notebook type touch input device and the foregoing is that the touch space 1133 can be switched to form a virtual slide. Any of the mouse 1136 and a virtual tablet 1137 can also achieve the effect of making the volume thin and light and lightweight.
Please refer to FIG. 4 , which is a perspective view of a third embodiment of the notebook computer touch input device of the present invention, and the corresponding relationship between the components and components of the notebook computer touch input device and the foregoing The notebook computer touch input device is the same, so it will not be described here. However, the main difference between the notebook computer touch input device and the foregoing is that the second body 11 has a groove portion 1121 and is recessed therein. The main surface 111 has a first sidewall 1121a, a second sidewall 1121b, a third sidewall 1121c opposite to the first sidewall 1121a, and a fourth sidewall 1121d opposite the second sidewall 1121b. The transmitters 1131 are respectively disposed on the first and second side walls 1121a, 1121b, and the receivers 1132 are respectively disposed on the third and fourth side walls 1121c, 1121d, and respectively opposite to the first and second sides. The transmitters 1131 on the side walls 1121a, 1121b; through the foregoing structural design, the transmitter 1131 can optically transmit signals to the receivers 1132 and jointly define the touch space 1133, which can replace the traditional notebook computer. Mechanical keyboard thickness is too large and cause excessive room disadvantages, and thus the thickness and the volume of the notebook computer can be significantly thinned and relatively light weight.
As described above, the present invention has the following advantages over the prior art:
1. Light and thin;
2. Low cost;
3. Longer life.
The present invention has been described in detail above, but the foregoing is only a preferred embodiment of the invention, and is not intended to limit the scope of the invention. That is, the equivalent changes and modifications made by the scope of the present application should remain within the scope of the patent of the present invention.
