For example, computers and mobile phones are equipped with keyboards, fax machines and projectors. The control of electronic products is also provided with buttons. The user can set the function by pressing the user command on the keyboard or panel. Due to the frequent nature of the button operation, 'there is a demand for the button device. For example, people want the button to be pressed without eccentricity or keying. In view of this, the Republic of China new patent No. M345269 discloses the "J ~ ^ device with a button slide rail", which has improved the traditional button, and has a button slide on the electronic button. A fixed component is provided, and by the movement of the button and the A-track control button, the occurrence of a card key or an eccentricity can be avoided when the button is pressed. However, since the slide rail of the above-mentioned button is in surface contact with its fixed member, the contact area is large, so when the button is pressed, the friction generated by the button is also large. This makes the button operation laborious and inconvenient to use. [New Content] The main purpose of this creation is to provide a button device that is smooth and labor-saving during key operation, thereby facilitating user use. In order to achieve the above objectives, the key device provided by the present invention includes a keycap and a chassis. The key cap has a pressing surface, and a side wall is formed on one side of the pressing surface, and the side wall and the pressing surface enclose an assembly space. The inner wall surface of the side wall is recessed with at least one guiding slot, and the guiding slot is vertical Set on the pressing surface. The M364265 is placed on the chassis with at least a guide spool. Wherein, the material is placed above the chassis, and the guide column of the chassis is inserted into the guide slot of the keycap, and the keycap can slide up and down along the guide column. As described above, since the guide groove of the key cap is in rear contact with the guide spool of the chassis, the key device of the present invention can reduce the contact area between the key cap and the chassis as compared with the prior art, thereby Reduce the friction, make the button process smooth and labor-saving, and convenient for users. [Embodiment] The technical contents, the objects and effects achieved by the present invention will be described in detail below with reference to the embodiments. Referring to the first figure and the second figure, the button device 1 can be used in a computer keyboard or a mobile phone keyboard. It can also be applied to a control panel of a fax machine or a projector, and includes a key cap 110 and a chassis. 120 and an elastic member 130 connected between the keycap 11 〇 and the chassis 120. Referring to the second and third figures, the keycap 11A has a quadrangular pressing surface 111, and the four side edges of the pressing surface 111 are respectively extended to one side to form a side plate 112. The side plate 112 serves as a side wall, and the pressing surface m serves as a top wall to collectively form an assembly space 113. A columnar connecting portion 114 is formed in the middle of the assembly space 113, and the connecting portion 114 is integrally formed on the bottom surface of the pressing surface 111. The side plates 112 are connected to each other, and a guide groove 115 is formed in a recess at at least one of the mutually connected corners. The guide groove 115 extends substantially in the upper and lower directions and is perpendicular to the pressing surface 111. Referring to the second figure, the chassis 120 has a substrate 121, which may be a part of the keyboard assembly housing of the keyboard or the outer casing of the electronic device for assembling the key towel from 110. A circular mounting portion 122 is recessed in the top surface of the substrate 121. A trigger circuit (not shown) of the switch can be disposed in the mounting portion 122. When the switch is depressed, the trigger circuit sends a signal. The peripheral projection M364265 of the mounting portion 122 is provided with a plurality of columnar posts 123. The column 123 is arranged on the substrate 121 with reference to the shape of the pressing surface 111 of the keycap ιι, and includes at least a guide 124 and a plurality of support columns 125. '
請參閱第二圖及第四圖，所述彈性件13〇呈圓台狀，係為 具彈性的絕緣材質（如橡膝等）製成’其頂部具有:外徑較: 的環狀之承載面131，底部具有一外徑較大的環狀之底面 132。彈性件130在其底面132上凹設有一彈性空間彈 性空間133内凸設有一啟動部134。所述承載面131的大小與 鍵帽110之連接部114的外徑相當’從而可以對接於鍵帽n〇 上；底面132的大小與底盤120之安裝部122的外徑相當，從 而可以裝設於底盤120上。 請參閱第五圖’本創作按鍵裝置100組裝時，首先將彈性 件130裝設於底盤120上’其環狀之底面132扣合在所述安裝 部122上’從而可對設置於安裝部i22内的觸發電路提供保護 作用’使其免受灰塵、水分等影響。彈性空間133内之啟動部 134正對觸發電路的觸發開關設置，從而當啟動部134被向下 移動時能觸發該觸發電路。 其後，將鍵帽110裝設於彈性件130的上方，且使其底面 之連接部114裝設在彈性件130的承載面131上，為使其連接 穩定，可將其對接面利用黏膠黏合。底盤120之導滑柱124插 入鍵帽110的導滑槽114中，從而使得鍵帽110可以沿導滑柱 124而上下滑動；鍵帽11〇之側板112的内側壁緊貼在所述支 撐柱125的外側，從而使得鍵帽11〇被壓下時保持水平。 請參閱第六圖’本創作按鍵裝置1〇〇被按下時，鍵帽11〇 沿導滑柱123向下滑動，從而向下壓縮彈性件13(μ彈性件13〇 的彈性空間133被壓縮時，帶動啟動部134亦向下移動而抵壓 在底盤120之觸發電路的開關上，從而可觸發一電訊號。 M364265 綜上所述，由於鍵帽110之導滑槽114與底盤12〇之導滑 柱124之間係為線接觸，故與習知技術相比，本創作按鍵裝置 100可減小鍵帽110與底盤120之間的接觸面積，從而減小摩 擦力，使按鍵過程變得順暢省力，方便用戶使用。 本創作藉由上述揭露之構造，可以達到所述目的及功效， 且本創作之申請合乎專利之要件，故依法提出申請。惟，以上 所揭露者，僅為本創作之較佳實施例，自不能以此限定本創作 之權利範圍。本創作之亦可有其他修飾或變化，皆應涵蓋在以 下本案之申請專利範圍内。 【圖式簡單說明】 第一圖係本創作按鍵裝置的立體圖。 第二圖係第一圖所示按鍵裝置的立體分解圖。 第三圖係第一圖所示按鍵裝置之鍵帽的立體圖。 第四圖係第一圖所示按鍵裝置之彈性件的立體圖。 第五圖係第一圖所示按鍵裝置之一剖視圖。 第六圖係第一圖所示按鍵裝置被壓下的示意圖。 【主要元件符號說明】 按鍵裝置 100 鍵帽 110 按壓面 111 側板 112 組裝空間 113 連接部 114 導滑槽 115 底盤 120 基板 121 安裝部 122 立柱 123 導滑柱 124 支撐柱 125 彈性件 130 承載面 131 底面 132 彈性空間 133 啟動部 134Referring to the second and fourth figures, the elastic member 13 is in the shape of a truncated cone, and is made of an elastic insulating material (such as a rubber knee). The top portion has an annular bearing with an outer diameter: The face 131 has a bottom surface 132 having a larger outer diameter. The elastic member 130 has a resilient space 133 recessed in the bottom surface 132 to define a starting portion 134. The bearing surface 131 is sized to correspond to the outer diameter of the connecting portion 114 of the keycap 110 so as to be docked on the keycap n〇; the size of the bottom surface 132 is equivalent to the outer diameter of the mounting portion 122 of the chassis 120, so that it can be installed On the chassis 120. Referring to the fifth figure, when the original button device 100 is assembled, the elastic member 130 is first mounted on the chassis 120. The annular bottom surface 132 is fastened to the mounting portion 122 so as to be disposed on the mounting portion i22. The internal trigger circuit provides protection from 'dust, moisture, etc.'. The activation portion 134 in the elastic space 133 is disposed adjacent to the trigger switch of the trigger circuit so that the trigger circuit can be triggered when the activation portion 134 is moved downward. Thereafter, the key cap 110 is mounted on the elastic member 130, and the connecting portion 114 of the bottom surface is mounted on the bearing surface 131 of the elastic member 130. To make the connection stable, the mating surface can be glued. Bonding. The guide strut 124 of the chassis 120 is inserted into the guide slot 114 of the keycap 110, so that the keycap 110 can slide up and down along the guide strut 124; the inner side wall of the side plate 112 of the keycap 11 is closely attached to the support post The outer side of the 125 is such that the keycap 11 is kept horizontal when it is depressed. Referring to the sixth figure, when the key device 1 is pressed, the keycap 11 slid downward along the guide spool 123, thereby compressing the elastic member 13 downward (the elastic space 133 of the μ elastic member 13 is compressed) When the starting portion 134 is also moved downward to press against the switch of the trigger circuit of the chassis 120, a signal can be triggered. M364265 In summary, since the guide slot 114 of the keycap 110 and the chassis 12 are closed The guide rails 124 are in line contact, so that compared with the prior art, the present button device 100 can reduce the contact area between the keycap 110 and the chassis 120, thereby reducing friction and making the button process become The invention is simple and labor-saving, and is convenient for the user to use.
