Description
本發明係關於一種按鍵結構總成,特別是針對按鍵之防水防塵功能達成而作的結構改良設計,透過於表面板金及背蓋板金間製設之防水墊片與矽膠墊片,特能達成全面性的防水防塵效果,同時組配上更為簡易而能減省產製成本,據以賦予極佳之產業利用價值者。 The invention relates to a button structure assembly, in particular to a structural improvement design for achieving a waterproof and dustproof function of a button, which can be achieved through a waterproof gasket and a silicone gasket formed between the surface sheet metal and the back cover gold. The comprehensive waterproof and dustproof effect, at the same time, the combination is simpler and can reduce the cost of production, so as to give excellent industrial use value.
按,一般加工機械或自動控制設備,經常會利用按鍵進行資料輸入及相關數值設定,而為了避免水漬、汗漬及灰塵進入其內部電路板,導致按鍵靈敏度變差或故障,所以在按鍵的設計上可能或選用薄膜式按鍵,但因此類薄膜式按鍵在反覆操作的接觸磨擦下,常會有破損之問題發生,其實用性與耐用度明顯不如機械式按鍵。 Press, general processing machinery or automatic control equipment, often use the button for data input and related value setting, and in order to avoid water stains, perspiration and dust entering its internal circuit board, resulting in button sensitivity deterioration or failure, so the design of the button On the other hand, the film type button may be used, but therefore, the film type button often has a problem of breakage under repeated contact friction, and its practicality and durability are obviously inferior to mechanical buttons.
惟,習知之機械式按鍵因係採單體組製於預設的基板上,為了取得按鍵按壓的靈活性,通常在按鍵與基板上會寸在有些微餘隙,藉以避免按鍵有摩擦卡死之虞,而該等餘隙的存在正提供了水漬及灰塵入侵的路徑,也因此導致機械式按鍵故障率偏高的問題,是以業者特別為按鍵的防水 防塵功能作了不少相關設計。 However, the conventional mechanical button is made of a single unit on a preset substrate. In order to obtain the flexibility of the button press, there is usually a slight clearance on the button and the substrate to avoid the button being frictionally stuck. Then, the existence of these clearances is providing a path for water and dust intrusion, which also leads to a problem of high mechanical button failure rate, which is especially waterproof for the button. The dustproof function has been designed in many related ways.
綜觀現有按鍵之防水防塵結構,通常係直接整合設計於按鍵單體的內部,藉以取得預期的防水防塵效能,然此種結構設計,為了取得按鍵的防水防塵功能,常會導致其按鍵結構的複雜化,雖可達預期功能,但因結構複雜而徒增組配難度,相對地導致整體組致成本的增加,實不利於產業利用價值,是以如合在達成按鍵的防水防塵功能外,更能兼顧其整體組製成本的減降,乃成為本發明致力研發之標的。 Looking at the waterproof and dustproof structure of the existing buttons, it is usually directly integrated into the interior of the button unit to achieve the expected waterproof and dustproof performance. However, in order to obtain the waterproof and dustproof function of the button, the button structure is often complicated. Although it can achieve the expected function, but due to the complexity of the structure and increase the difficulty of the combination, the relative cost of the overall group is relatively increased, which is not conducive to the value of industrial use, so that it is better to achieve the waterproof and dustproof function of the button. The reduction of the overall group cost is the subject of the research and development of the present invention.
有鑑於習知按鍵在其防水防塵功能的設計上,必須透過複雜的結構來達成,導致其整體產製成本偏高,相對地影響產業經濟效益,基於此,發明人特著手進行研發設計,基於其從事相關產業之多年經驗與技術,進而研創出本發明之按鍵結構總成。 In view of the design of the waterproof and dustproof function of the conventional button, it must be achieved through a complicated structure, resulting in a high overall production cost, which relatively affects the economic benefits of the industry. Based on this, the inventor specially works on R&D and design, based on It has been engaged in many years of experience and technology in related industries, and has further developed the key structure of the present invention.
為達成按鍵的防水防塵效能,同時能在產製成本方面獲得減降,本發明於按鍵的結構設計上,乃於按鍵組設之表面板金底部結合一背蓋板金,並在兩者之間夾設一防水墊片及矽膠墊片,藉以將按鍵與電路板上佈設的鍵體取得全面性的區隔關係,使其在不影響按鍵壓觸控制功能的原則下,可賦予更佳之防水防塵效果,同時可據以達到產製成本的減降者。 In order to achieve the waterproof and dustproof performance of the button, and at the same time, the reduction in the production cost can be achieved. The structure design of the button in the present invention is combined with a back cover gold at the bottom of the surface of the button assembly, and between the two. A waterproof gasket and a silicone gasket are interposed to obtain a comprehensive separation relationship between the button and the key body disposed on the circuit board, so that it can be better waterproof and dustproof without affecting the function of the button pressure control function. The effect, at the same time, can be used to achieve the cost reduction of the production.
本發明之按鍵結構總成,在不影響按鍵的操控性能下,透過整片式矽膠墊片及防水墊片取得對電路板鍵體的全面性區隔達成預期的防水防塵效能,因其係採整片式區隔,而非習知按鍵單體的防水設計,所以在結構上可獲得大幅簡化,更得以使組配上更為簡易,從而減降其整體產製成本,賦予更佳之產業利用價值者。 The button structure assembly of the invention achieves the expected waterproof and dustproof performance of the comprehensive division of the circuit board key body through the whole piece of the rubber gasket and the waterproof gasket without affecting the manipulation performance of the button, The whole piece is separated from the waterproof design of the conventional button, so the structure can be greatly simplified, and the assembly can be made easier, thereby reducing the overall cost of production and giving better industrial utilization.

Similarly, the elastic inlay 64 of the tool 80 from the joint portion 63 of the button base 60 can also be used. Inserting one of the tools allows the tool 80 to be pressed against the hook 62 of the lower edge of the button insert 60 of the button base 60 to be deformed to be disengaged from the set hole 51 of the surface sheet 50, thereby allowing the button base 60 to be self-surfaced. The set hole 51 is pulled out to facilitate the replacement of the button base 60. In other words, all the button bases 60 and 70 of the button assembly of the present invention can be replaced as needed, and in the aforementioned button base 60. The inner side wall of the groove 66 of the top surface is provided with a pair of limiting ribs 67 for engaging the button 70. The side edge of the surface 74 corresponds to the limiting groove 76, which can form a limit and guide action when the button 70 is pressed, so that the button 70 can be stably pressed down and lifted by the reset of the key body 11 while avoiding Because the pressing force is too large, the central cylinder 72 of the button 70 injures the key body 11 and the circuit board 10; summarizing the above description, the button structure assembly of the present invention passes through the waterproof pad made of the surface plate gold and the back cover gold. The sheet and the gold-filled groove in the back cover are filled with the adhesive and the silicone gasket, and the special board can be assembled on the circuit board. The key body forms a comprehensive covering and isolation, so as to achieve better waterproof and dustproof effect, and at the same time, the combination is simpler and can reduce the production cost, which can really give excellent industrial utilization value. Overall, it is true. An excellent and outstanding innovative design, 提出 filed a patent application according to law.
