下面將結合附圖及具體實施例對本發明觸摸屏輸入指套作進一步的詳細說明。 The touch screen input finger sleeve of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
請參見圖1，本發明第一實施例提供一種觸摸屏輸入指套10，其包括一手指套筒12及一輸入端14，所述輸入端14與手指套筒12可拆卸的相互連接在一起，整體上呈一端封閉另一端敞開形態，所述輸入端14位於該封閉端處，使用時使人的手指能夠與該輸入端14電連接。 Referring to FIG. 1 , a first embodiment of the present invention provides a touch screen input finger sleeve 10 including a finger sleeve 12 and an input end 14 . The input end 14 and the finger sleeve 12 are detachably connected to each other. The one end is closed at one end and the other end is open. The input end 14 is located at the closed end, and in use enables a human finger to be electrically connected to the input end 14.

The flexible insulating material includes resin, rubber, plastic, and flexible fibers. The flexible conductive material may be a conductive polymer material or a conductive material formed by adding metal particles to the flexible insulating material. The finger sleeve 12 has a cylindrical structure and may be open at both ends, or may be closed at one end and open at the other end. If the material of the finger sleeve 12 is an insulating material, the input end 14 needs to be mounted on the finger sleeve 12 in a manner that is in contact with the fingers. When the finger sleeve When the two ends of the 12 are open, the input end 14 can be directly fixed to one end of the finger sleeve 12, and the finger can directly contact the input end 14; when the end of the finger sleeve 12 is closed, it needs to be at the closed end. At least one through hole is opened, and the input end 14 is disposed on the inner wall surface or the outer wall surface of the closed end, and the finger can directly contact the input end 14 or contact the input end 14 through the hole. In this embodiment, the finger sleeve 12 is open at both ends, and the finger sleeve 12 is used for fixing the input end 14 to the finger of the touch screen and electrically connecting the finger to the input end 14 . The size of the finger is determined by the thickness of the finger, generally slightly smaller than the diameter of the finger, and the finger sleeve 12 itself has a certain elasticity and can be fixed on the finger. The wall thickness of the finger sleeve 12 can be selected to be 0.1 mm to 2 mm.
所述輸入端14用於傳導觸摸屏螢幕與手指之間的電流，從而使觸摸屏輸入指套10向觸摸屏輸入信號。所述輸入端14的形狀不限，可以為球形、錐形、橢球形或其他不規則形狀。所述輸入端14可以通過卡扣、過盈配合等機械方式或者熱壓、黏結劑等物理化學方式固定於所述手指套筒12的一端。本實施例中，所述輸入端14通過黏結劑與手指套筒12固定。所述輸入端14按照與手指套筒12的位置關係可以分為第一部分142及第二部分144。所述第一部分位於手指套筒12的內部，用於與手指相互接觸。所述第二部分144位於手指套筒12的外部，用於向觸摸屏輸入信號。所述第一部分142與手指接觸的表面可以具有一定的曲面，使使用者的手指的指腹與該曲面接觸時具有更好的觸感。所述第二部分144可具有一尖端或凸起結構，便於操作較小的按鍵。可選擇地，在輸入端14與手指套筒12相接觸的側面還可以包括一縫隙16，該縫隙16用於容納手指甲，使人在使用該觸摸屏輸入指套時更加舒適。 The input terminal 14 is for conducting current between the touch screen screen and the finger, thereby causing the touch screen input finger sleeve 10 to input a signal to the touch screen. The shape of the input end 14 is not limited and may be spherical, conical, ellipsoidal or other irregular shape. The input end 14 can be fixed to one end of the finger sleeve 12 by mechanical means such as snapping or interference fit, or physical and chemical means such as hot pressing and bonding. In this embodiment, the input end 14 is fixed to the finger sleeve 12 by a bonding agent. The input end 14 can be divided into a first portion 142 and a second portion 144 according to the positional relationship with the finger sleeve 12. The first portion is located inside the finger sleeve 12 for contacting the fingers. The second portion 144 is located outside of the finger sleeve 12 for inputting signals to the touch screen. The surface of the first portion 142 in contact with the finger may have a curved surface so that the finger pad of the user's finger has a better tactile sensation when in contact with the curved surface. The second portion 144 can have a pointed or raised configuration for facilitating the operation of smaller keys. Alternatively, the side of the input end 14 that contacts the finger sleeve 12 may also include a slit 16 for receiving the fingernail, making it more comfortable for the person to use the touch screen to input the finger cuff.
本實施例中，所述輸入端14包括一支撐體146及設置於支撐體146表面的導電層148。支撐體146可以為空心結構，也可以為實心結構。所述支撐體146的材料不限，可以由硬性材料或柔性材料製成。當該支撐體146的材料選擇硬性材料時，其可以為陶瓷、玻璃、樹脂、石英、塑膠等中的一種或幾種。當支撐體146選擇柔性材料時，其可以為樹脂、橡膠、塑膠或柔性纖維等中的一種或幾種。所述支撐體146還可以為導電高分子材料，導電高分子材料具有較高的介電常數，用作支撐體146時，可以使輸入端14本身具有較大的電容。所述導電高分子材料可以為聚苯胺、聚吡咯或聚噻吩。所述支撐體146還可以為具有較高介電常數的液體，如水、離子溶液。當支撐體146採用液體時，可以使輸入端14具有一定的柔性，該觸摸屏輸入指套10與觸摸屏接觸時，不會對螢幕造成劃傷。當支撐體146為空心結構時，可以使該輸入端14的質量較輕，且可以節省材料。當支撐體146的材料為柔性材料時，輸入端14可以具有一定的柔性，對觸摸屏具有一定的保護作用，且輸入端14具有一定的耐彎折性能，可以提高輸入端14的壽命。同時，由於輸入端14具有一定的柔性，可以通過觸摸壓力來控制輸入端14與觸摸屏之間的接觸面積的大小，從而控制輸入信號。 In this embodiment, the input end 14 includes a support body 146 and a conductive layer 148 disposed on the surface of the support body 146. The support body 146 may be a hollow structure or a solid structure. The material of the support body 146 is not limited and may be made of a hard material or a flexible material. When the material of the support body 146 is selected from a hard material, it may be one or more of ceramic, glass, resin, quartz, plastic, and the like. When the support 146 selects a flexible material, it may be one or more of resin, rubber, plastic or flexible fiber. The support body 146 can also be a conductive polymer material. The conductive polymer material has a high dielectric constant. When used as the support body 146, the input end 14 itself can have a large capacitance. The conductive polymer material may be polyaniline, polypyrrole or polythiophene. The support 146 may also be a liquid having a higher dielectric constant such as water or an ionic solution. When the support body 146 is made of liquid, the input end 14 can be made flexible, and the touch screen input finger sleeve 10 does not scratch the screen when it is in contact with the touch screen. When the support body 146 is a hollow structure, the input end 14 can be made lighter in weight and material can be saved. When the material of the support body 146 is a flexible material, the input end 14 can have a certain flexibility, and has a certain protection effect on the touch screen, and the input end 14 has a certain bending resistance, and the life of the input end 14 can be improved. At the same time, since the input end 14 has a certain flexibility, the contact area between the input end 14 and the touch screen can be controlled by the touch pressure, thereby controlling the input signal.
所述導電層148為由導電材料構成，其作為用於傳導觸摸屏螢幕與手指之間的電流，從而使觸摸屏輸入指套10向觸摸屏輸入信號。即，使用時，觸摸屏輸入指套10的導電層148與使用者手指電連接。 The conductive layer 148 is composed of a conductive material for conducting current between the touch screen screen and the finger, thereby causing the touch screen input finger sleeve 10 to input a signal to the touch screen. That is, in use, the conductive layer 148 of the touch screen input finger cuff 10 is electrically connected to the user's finger.
所述導電層148可以為一石墨烯層。請參見圖2，石墨烯係由複數 個六元環型的碳原子構成的片層狀結構。石墨烯覆蓋在支撐體146的表面構成石墨烯層，該石墨烯層中的石墨烯通過凡得瓦力相互連接。該石墨烯層中的石墨烯的排列方式可以為相互交疊設置、並列設置或者相互重合設置。石墨烯具有良好的導電性能，其在室溫下傳遞電子的速度非常快。所述石墨烯的厚度小於等於100奈米，本實施例中，石墨烯的厚度為0.5奈米至100奈米。所述石墨烯層的厚度為單層石墨烯的厚度至1毫米。本實施例中，採用化學分散法製備石墨烯材料。化學分散法係將氧化石墨與水按照1mg：1mL的比例混合，用超聲波振盪至溶液清晰無顆粒狀物質，加入適量肼在100℃回流24h，產生黑色顆粒狀沉澱，過濾、烘乾即得石墨烯粉末。制得石墨烯之後，將支撐體146放入石墨烯粉末中，由於石墨烯為奈米材料，本身具有一定的黏附力，可以黏附在支撐體146的表面，形成導電層148。可以理解，石墨烯也可以通過黏結劑固定於支撐體146的表面。石墨烯係奈米材料，具有較高的比表面積，作為導電層148使用時，導電層148與觸摸屏直接接觸，由於石墨烯的比表面積較大，可以與觸摸屏之間產生較大的電容，故，可以使該觸摸屏輸入指套10具有較高的靈敏度。且，石墨烯較光滑，具有較小的摩擦係數，在使用時不會對觸摸屏的螢幕造成傷害。 The conductive layer 148 can be a graphene layer. Please refer to Figure 2, graphene is composed of plural A sheet-like structure composed of six-membered ring-shaped carbon atoms. The graphene coating on the surface of the support 146 constitutes a graphene layer, and the graphene in the graphene layer is connected to each other by van der Waals force. The graphene in the graphene layer may be arranged in an overlapping manner, arranged side by side, or overlapped with each other. Graphene has good electrical conductivity and it delivers electrons very quickly at room temperature. The thickness of the graphene is less than or equal to 100 nm. In the present embodiment, the thickness of the graphene is from 0.5 nm to 100 nm. The thickness of the graphene layer is a thickness of a single layer of graphene to 1 mm. In this embodiment, a graphene material is prepared by a chemical dispersion method. The chemical dispersion method combines graphite oxide and water in a ratio of 1 mg: 1 mL, and shakes with ultrasonic waves until the solution is clear and free of particulate matter. After adding an appropriate amount of rhodium at 100 ° C for 24 h, a black granular precipitate is produced, and the graphite is obtained by filtration and drying. Alkene powder. After the graphene is obtained, the support 146 is placed in the graphene powder. Since the graphene is a nano material, it has a certain adhesion force and can adhere to the surface of the support 146 to form the conductive layer 148. It can be understood that the graphene can also be fixed to the surface of the support 146 by a binder. The graphene-based nano-material has a high specific surface area. When used as the conductive layer 148, the conductive layer 148 is in direct contact with the touch screen. Since the specific surface area of the graphene is large, a large capacitance can be generated between the touch screen and the touch screen.
