Description
本案是有關於一種觸控筆,且特別是有關於一種包括天線的觸控筆。 This case relates to a stylus, and in particular to a stylus including an antenna.
隨著科技的進步,目前大眾的通訊方式已漸漸改為無線通訊,像是智慧型手機(smart phone)、具有無線上網功能的平板電腦(tablet PC)及筆記型電腦(notebook computer)等等,甚至是觸控筆皆是無線通訊的範疇。一般而言,無線通訊需要利用天線來傳遞訊息。 With the advancement of technology, the current communication method of the masses has gradually changed to wireless communication, such as smart phones, tablet PCs with wireless Internet access, and notebook computers. Even the stylus is a category of wireless communication. In general, wireless communication requires the use of an antenna to transmit messages.
以觸控筆為例,為了因應外觀設計需求或其他設計上的需求,觸控筆常使用金屬或其他導電材料作為外殼的材料。然而,若觸控筆具有導電殼體,會導致其天線的訊號受到導電殼體的干擾。為此,需要新的設計以改善配置在導電殼體的天線的訊號收發效率。 Taking the stylus as an example, in order to meet the design requirements or other design requirements, the stylus often uses metal or other conductive materials as the material of the outer casing. However, if the stylus has a conductive housing, the signal of its antenna may be disturbed by the conductive housing. To this end, new designs are needed to improve the signal transceiving efficiency of the antennas disposed in the conductive housing.
本案提供一種觸控筆,其天線具有良好的訊號收發效率。 The present invention provides a stylus whose antenna has good signal transmission and reception efficiency.
本案提出一種觸控筆,包括一導電筆桿、一電路板以及一天線。導電筆桿具有一第一開孔。電路板配置在導電筆桿內且具有一接地部,其中導電筆桿電性連接於接地部。天線包括一輻射部及一饋入部,其中饋入部電性連接 於電路板且經由第一開孔從導電筆桿內伸至導電筆桿外,輻射部位於導電筆桿外且電性連接於饋入部。 The present invention proposes a stylus comprising a conductive stylus, a circuit board and an antenna. The conductive pen holder has a first opening. The circuit board is disposed in the conductive pen and has a grounding portion, wherein the conductive pen is electrically connected to the ground. The antenna includes a radiating portion and a feeding portion, wherein the feeding portion is electrically connected The radiating portion is located outside the conductive pen holder and electrically connected to the feeding portion, and extends from the conductive pen to the outside of the conductive pen holder through the first opening.
基於上述,本案的觸控筆的導電筆桿接地於電路板的接地面,以降低導電筆桿對觸控筆之天線造成的干擾。藉此,在觸控筆的筆桿的材質因應外觀設計需求或其他設計上的需求而選用金屬等導電材料的情況下,天線仍可具有良好的訊號收發效率。 Based on the above, the conductive pen of the stylus of the present invention is grounded on the grounding surface of the circuit board to reduce the interference caused by the conductive pen to the antenna of the stylus. Therefore, in the case where the material of the stylus pen is made of a conductive material such as metal according to the design requirements or other design requirements, the antenna can still have good signal transmission and reception efficiency.

Referring to FIG. 12B, in the embodiment, the end of the radiating portion 232c includes a bump 240, and the bump 240 is located between the radiating portion 232c and the conductive pen 210c. The bump 240 may be made of a non-conductor material. The equivalent capacitance is formed between the radiation portion 232c and the conductive sheath 210c by using the bump 240 and the air as a medium. In detail, the thickness or width of the bump 240 can be adjusted to change the value of the equivalent capacitance, thereby adjusting the antenna 230c. The impedance matching improves the transmission and reception efficiency of the antenna 230c. In addition, the antenna 230c of the embodiment can be used as a pen holder of the stylus pen 200c, and the bump 240 can be used as a fastening portion at the end of the pen holder. When the user fixes the stylus pen 200c at an arbitrary position by using the antenna 230c, The fastening portion has the function of strengthening the fixing effect.
圖13A是依照本案之第八實施例之觸控筆的立體示意圖。圖13B是圖13A的側視示意圖。圖13A的實施例實質上與圖8A的實施例相似,兩者的差別主要在於天線接地的形式。請同時參考圖13A與圖13B,在本實施例中, 天線330例如是一平面倒F型天線(Planar Inverted F Antenna,PIFA),其包括一輻射部332、一饋入部334以及一接地段336。導電筆桿310具有一第一開孔312以及一第二開孔314,饋入部334經由第一開孔312從導電筆桿310內伸至導電筆桿310外,且接地段336經由第二開孔314從導電筆桿310外伸至導電筆桿310內以連接於電路板320的接地部322,可降低導電筆桿310對天線330的干擾,使得天線330可提供良好的訊號收發效率。 FIG. 13A is a perspective view of a stylus according to an eighth embodiment of the present invention. Figure 13B is a side elevational view of Figure 13A. The embodiment of Figure 13A is substantially similar to the embodiment of Figure 8A, the difference being primarily due to the form in which the antenna is grounded. Please refer to FIG. 13A and FIG. 13B at the same time. In this embodiment, The antenna 330 is, for example, a Planar Inverted F Antenna (PIFA), and includes a radiating portion 332, a feeding portion 334, and a grounding portion 336. The conductive pen holder 310 has a first opening 312 and a second opening 314. The feeding portion 334 extends from the conductive pen holder 310 through the first opening 312 to the outside of the conductive pen holder 310, and the grounding portion 336 passes through the second opening 314. The conductive pen holder 310 extends into the conductive pen holder 310 to be connected to the ground portion 322 of the circuit board 320, which can reduce the interference of the conductive pen holder 310 to the antenna 330, so that the antenna 330 can provide good signal transceiving efficiency.
在此需說明的是,圖13A的觸控筆300的饋入部334及接地段336可以是伸縮結構,且適於伸縮以改變輻射部332與導電筆桿310之間的距離。此部分的說明可參考圖10A與圖10B的實施例,在此不再贅述。 It should be noted that the feeding portion 334 and the grounding portion 336 of the stylus pen 300 of FIG. 13A may be a telescopic structure and are adapted to expand and contract to change the distance between the radiating portion 332 and the conductive pen holder 310. For the description of this part, reference may be made to the embodiment of FIG. 10A and FIG. 10B, and details are not described herein again.
綜上所述,本案的觸控筆的導電筆桿接地於電路板的接地部,以降低導電筆桿對觸控筆之天線造成的干擾。藉此,在觸控筆的筆桿的材質因應外觀設計需求或其他設計上的需求而選用金屬等導電材料的情況下,天線仍可具有良好的訊號收發效率。此外,可將天線的輻射部設計為可相對於導電筆桿作動(如轉動或滑動等作動方式),使輻射部能夠遠離於導電筆桿以進一步降低電筆桿對觸控筆之天線造成的干擾。 In summary, the conductive pen of the stylus of the present invention is grounded to the grounding portion of the circuit board to reduce the interference caused by the conductive pen to the antenna of the stylus. Therefore, in the case where the material of the stylus pen is made of a conductive material such as metal according to the design requirements or other design requirements, the antenna can still have good signal transmission and reception efficiency. In addition, the radiating portion of the antenna can be designed to be movable relative to the conductive pen (such as rotating or sliding) to enable the radiating portion to be away from the conductive pen to further reduce the interference of the electric pen to the antenna of the stylus.
雖然本案已以實施例揭露如上,然其並非用以限定本案,任何所屬技術領域中具有通常知識者,在不脫離本案之精神和範圍內,當可作些許之更動與潤飾,故本案之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone having ordinary knowledge in the technical field can protect the case without any deviation and refinement within the spirit and scope of the present case. The scope is subject to the definition of the scope of the patent application attached.
