Description

防水^ ^结构和手机 技术领域
本实用新型涉及手机按键结构技术领域， 尤其涉及一种防水按键结构 和手机。 背景技术
防水手机因其独特的性能越来越受到消费者喜爱， 市场上防水手机也 越来越多。 目前常规的手机按键防水方案如图 1所示： 手机的上壳 1与下 壳 2通过防水圈 3过盈防水， 按键开孔处通过防水软胶 5与旧上壳 1与下 壳 2过盈防水， 防水软胶 5通过模内钢片 6支撑保证位置精度， 通过外边 的按键 4的导电柱 8按压防水软胶 5的弹性壁 7， 以传递一压力给弹性壁 7 从而触发 DOME或者按键触发器。 这种结构的缺点在于， 防水软胶 5需要 较大厚度的弹性壁 8，导致手机整机厚度偏厚。通常需要导电柱直径在 2mm 左右， 另外还需要有 lmm左右的弹性壁 7， 因此， 无法满足目前手机越来 越薄的设计要求。 另外通过防水软胶与按键接触时按键手感不好， 而且， 防水软胶 5因多次接触很容易被按键 4开关刺破。 发明内容
本实用新型实施例的主要目的是提供一种厚度较小且按键寿命较高的 防水按键结构和手机。
为了达到上述目的， 本实用新型实施例的技术方案是这样实现的： 一种防水按键结构， 包括按键触发器、 按键以及设在所述按键触发器 和按键之间的防水软胶； 还包括穿设于所述防水软胶且与该防水软胶密封 连接的导电柱， 该导电柱一端与所述按键触发器抵接、 另一端与所述按键 抵接实现按键按压功能。
其中， 所述按键靠近所述导电柱一侧设有用于与所述导电柱抵接的凸 起部。
其中， 还包括套设于所述导电柱上靠近所述按键一侧的支撑圈。 其中， 所述防水软胶与手机上壳和手机下壳为过盈配合。
其中， 还包括设在所述手机上壳与所述手机下壳之间以用于密封所述 手机上壳与手机下壳之间的密封圈。
一种手机， 包括上述的防水按键结构。
本实用新型实施例提出的防水按键结构， 通过设置在防水软胶单独的 导电柱连接按键与按键触发器， 不同于原有的与按键一体的导电柱， 可调 整导电柱的大小使本防水按键结构厚度较小， 以适应超薄手机的结构需要。 此外， 通过单独的导电柱去按压按键触发器以代替原来的防水软胶按压按 键触发器， 保证了按键手感， 此外， 可以因导电柱可金属件或者塑胶件来 取代原来的防水软胶， 避免防水软胶因多次接触很容易被按键刺破， 从而 提高本防水按键结构的寿命， 同时结构简单、 容易实现。 附图说明
图 1为现有技术中防水手机侧键的结构示意图；
图 2 为本实用新型防水按键结构较佳实施例的按键装入前的结构示意 图；
图 3 为本实用新型防水按键结构较佳实施例的按键装入后的结构示意 图。 具体实施方式
下面结合附图及具体实施例就本实用新型的技术方案做进一步的说 明。 应当理解， 此处所描述的具体实施例仅仅用以解释本实用新型， 并不 用于限定本实用新型。
本实用新型实施例提出一种防水按键结构。
参照图 2和图 3，图 2为本实用新型防水按键结构较佳实施例的按键装 入前的结构示意图； 图 3 为本实用新型防水按键结构较佳实施例的按键装 入后的结构示意图。
本实施例中， 提出一种防水按键结构， 该防水按键结构包括手机上壳 10与手机下壳 20， 手机上壳 10与手机下壳 20组装在一起。 其中在手机上 壳 10上还设有按键触发器 11， 防水按键结构还包括按键 30以及设在按键 触发器 11和按键 30之间的防水软胶 40， 防水软胶 40将手机上壳 10与手 机下壳 2020密封。 防水按键结构还包括穿设于防水软胶 40且与该防水软 胶 40密封连接的导电柱 50， 该导电柱 50—端与按键触发器 11抵接、 另一 端与按键 30抵接实现按键 30按压功能。 具体地， 按键 30靠近导电柱 50 一侧设有用于与导电柱 50抵接的凸起部 31。 导电柱 50可采用模内注塑金 属件或者塑胶件来实现， 导电柱 50形状可以采用圓形或者方形， 本实用新 型实施例在此不作限制。 本实施例中， 按键触发器 11 为按键连接器或者 DOME。
本防水按键结构在实现按键功能时，将按压按键使按键 30的凸起部 31 与导电柱 50抵接， 从而使导电柱 50受到压力， 从而向按键触发器 11处运 动， 从而实现按键按压功能。
本防水按键结构通过设置在防水软胶 40单独的导电柱 50连接按键 30 与按键触发器 11， 不同于原有的与按键 30—体的导电柱 50， 可调整导电 柱 50的大小使本防水按键结构厚度较小，以适应薄手机的结构需要。此外， 通过单独的导电柱 50去按压按键触发器 11以代替原来的防水软胶 40按压 按键触发器 11， 保证了按键手感， 此外， 可以因导电柱 50可金属件或者塑 胶件来取代原来的防水软胶 40，避免防水软胶 40因多次接触很容易被按键 30刺破， 从而提高本防水按键结构的寿命， 同时结构简单、 容易实现。
本实施例中， 防水按键结构还包括套设于导电柱 50上靠近按键 30一 侧的支撑圈 60。 可以防止导电柱 50再去触发按键连接器或者 DOME等侧 键开关实现侧键按压功能， 可能产生的导电柱 50晃动。
进一步地， 本防水按键结构还包括设于防水软胶 40内用于对的防水软 胶 40定位的钢片 41。 本实施例中， 防水软胶 40与手机上壳 10和手机下壳 20为过盈配合， 从而保证本防水按键结构的防水性能。
进一步地， 本防水按键结构还包括设在手机上壳 10与下壳之间以用于 密封手机上壳 10与手机下壳 20之间的密封圈 70， 进而进一步提高本防水 按键结构的防水性能。
本实用新型实施例进一步还提出一种手机。
本实施例中， 一种手机包括防水按键结构， 该防水按键结构的具体结 构参照上述实施例， 在此不再赘述。
本实用新型实施例提出的手机， 通过在防水按键结构上设置在防水软 胶单独的导电柱连接按键与按键触发器， 不同于在与按键一体的导电柱， 可调整导电柱的大小使本防水按键结构厚度较小， 以适应薄手机的结构需 要。 此外， 通过单独的导电柱去按压按键触发器以代替原来的防水软胶按 压按键触发器， 保证了按键手感， 此外， 可以因导电柱可金属件或者塑胶 件来取代原来的防水软胶， 避免防水软胶因多次接触很容易被按键刺破， 从而提高本防水按键结构的寿命， 同时结构简单、 容易实现。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
