Description

按键及电子设备
本申请要求于2021年09月06日提交中国专利局、申请号为202111037450.4，申请名称为“按键及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及终端技术领域，特别涉及一种按键及电子设备。
背景技术
目前，电脑、手机等电子设备已经和我们的生活密不可分，生活中随处可见，且极大地提高了人们的生活水平。随着消费者的使用需求的不断提升，对电子设备的要求也不断提升，轻薄化的电子设备逐渐进入了人们的视野。
以手机为例，随着手机屏幕和手机电池盖的曲面造型越来越普遍，手机中框的外观空间被严重压缩，而手机的侧按键成为中框减窄的瓶颈。相关技术中，为了避免手机的侧按键对手机的中框尺寸造成影响，一般使用虚拟侧按键代替物理侧按键的设计。
然而，上述采用虚拟侧按键的方案中，虚拟侧按键的灵敏度较低，且虚拟侧按键容易发生失效，对用户的使用体验造成较大影响。
发明内容
本申请提供一种按键及电子设备，能够在减小或消除对手机中框的尺寸造成影响的同时，避免产生按键不灵敏甚至失效，对用户的使用体验造成较大影响的问题。
第一方面，本申请实施例提供一种按键，应用于电子设备中，该按键至少包括：内键以及外键；所述内键靠近所述外键的一端的至少部分嵌设在所述外键的内部；所述外键包括：按压面以及与按压面相背的背面，所述内键设在所述外键的所述背面上；所述内键至少包括：功能部；所述外键在所述按键的宽度方向上的尺寸与所述功能部的至少部分在所述按键的宽度方向上的尺寸相同；所述外键在所述按键的长度方向上的其中一个外侧壁与所述功能部在所述按键的长度方向上的其中一个外侧壁相齐平；所述外键在所述按键的长度方向上的另一个外侧壁与所述功能部在所述按键的长度方向上的另一个外侧壁相齐平。
本申请实施例提供的按键，通过将内键设在外键的背面上，且外键在按键的宽度方向上的尺寸与内键的功能部的至少部分在按键的宽度方向上的尺寸相同，即外键的侧边缘与内键的功能部的至少部分的侧边缘相齐平，能够实现最大化减窄按键的整体宽度，这样能够减小按键在沿着电子设备的厚度方向上的尺寸，从而能够减小按键在中框上的设计尺寸，减小或消除对电子设备的中框的尺寸造成影响，进而有利于将中框在沿着电子设备的厚度方向上的尺寸减薄，以实现电子设备整体的轻薄化。另外，通过上述设置，还能够避免现有技术中采用虚拟化指纹识别按键时容易产生按键不灵 敏甚至失效，对用户的使用体验造成较大影响的问题。
另外，内键靠近外键的一端的部分嵌设在外键的内部，能够确保内键与外键配合时的可靠性能，避免内键与外键之间发生分离。内键靠近外键的一端的全部嵌设在外键的内部，相对于部分嵌设，能够在更大程度上确保内键与外键配合时的可靠性能，进一步避免内键与外键之间发生分离。外键在按键的长度方向上的两个外侧壁与内键的功能部在按键的长度方向上的两个外侧壁相互齐平，能够确保外键在按键的宽度方向的尺寸与内键的功能部在按键的宽度方向上的尺寸相同，这样能够实现最大化减窄按键的整体宽度，从而能够减小按键在沿着电子设备的厚度方向上的尺寸，进而能够减小按键在中框上的设计尺寸。
在一种可能的实现方式中，所述内键还包括：第一连接部；所述第一连接部的一端与所述功能部相连，所述第一连接部的另一端与所述电子设备的中框相连。通过设置第一连接部，能够实现内键与中框的相连。

在一种可能的实现方式中，所述第二连接部在所述按键的宽度方向上的尺寸小于或等于所述功能部在所述按键的宽度方向上的尺寸。这样，能够保证功能部作为内键中在按键的宽度方向上尺寸最大的单元，避免第二连接部增大内键的整体宽度。
在一种可能的实现方式中，所述功能部在所述按键的长度方向上的外侧壁与所述外键在所述按键的长度方向上的外侧壁之间的距离小于所述第二连接部在所述按键的长度方向上的外侧壁与所述外键在所述按键的长度方向上的外侧壁之间的距离。
也就是说，第二连接部在按键的宽度方向上的尺寸小于功能部在按键的宽度方向上的尺寸，这样，当功能部在按键的长度方向上的外侧壁与外键在按键的长度方向上的外侧壁相互齐平时，能够使得第二连接部在按键的长度方向上的外侧壁与外键在按键的长度方向上的外侧壁之间在按键的宽度方向上存在间隔，该间隔会在外键朝向内键的一面上形成用于封胶的台阶面。
在一种可能的实现方式中，所述第二连接部靠近所述功能部的一端在所述按键的长度方向上的至少一个外侧壁上设有至少一个缺口，以使所述外键与所述第一连接部相对位置处的至少部分所述背面裸露。外键与第一连接部相对位置处的至少部分背面裸露，外键的背面所裸露的区域即可用于封胶。
在一种可能的实现方式中，所述缺口的底壁为倾斜面。通过将缺口的底壁设置为倾斜面，能够增加封胶工艺的可行性。
在一种可能的实现方式中，所述外键在所述按键的宽度方向上的尺寸小于1.5mm。
第二方面，本申请实施例提供一种电子设备，该电子设备至少包括：中框、电路板以及至少一个上述任一所述的按键；所述按键的内键与所述中框相连；还包括：柔性电路板；所述内键通过所述柔性电路板与所述电路板电连接。
本申请实施例提供的电子设备，该电子设备至少包括按键，该按键通过将内键设在外键的背面上，且外键在按键的宽度方向上的尺寸与内键的功能部的至少部分在按键的宽度方向上的尺寸相同，即外键的侧边缘与内键的功能部的至少部分的侧边缘相 齐平，能够实现最大化减窄按键的整体宽度，这样能够减小按键在沿着电子设备的厚度方向上的尺寸，从而能够减小按键在中框上的设计尺寸，减小或消除对电子设备的中框的尺寸造成影响，进而有利于将中框在沿着电子设备的厚度方向上的尺寸减薄，以实现电子设备整体的轻薄化。另外，通过上述设置，还能够避免现有技术中采用虚拟化指纹识别按键时容易产生按键不灵敏甚至失效，对用户的使用体验造成较大影响的问题。
在一种可能的实现方式中，还包括：至少一个按键开关；所述按键开关与所述柔性电路板电连接；且所述按键开关与所述按键配合。这样，按压或触摸按键即可触发按键开关，而且，按键开关与柔性电路板电连接，柔性电路板与电路板电连接，能够确保按键开关与电路板之间电连接，从而确保按键开关的使用性能。
在一种可能的实现方式中，所述按键的数量为两个，其中一个所述按键与一个所述按键开关相对；另一个所述按键的两端分别与两个所述按键开关相对。
在一种可能的实现方式中，所述中框包括中板以及与所述中板相连的边框；所述边框上开设至少一个开口，所述按键位于所述开口处。这样，按键可以穿设在开口中，而且按键背离边框的一端可以裸露设置。

本申请实施例中，前置摄像模组160a和后置摄像模组160b的设置位置可以包括但不限于上述描述。其中，在一些实施例中，手机200内设置的前置摄像模组160a和后置摄像模组160b的数量可以为1个或N个，N为大于1的正整数。
另外，手机200的侧面一般还设置有按键，例如电源键和音量键，按键一般是位于中框120的侧边框122上，但当手机200受外观要求所限时，手机200厚度尺寸紧张，手机200的中框120的外观空间被严重压缩，而手机200的侧按键则成为中框120减窄的瓶颈。相关技术中，为了避免手机200的侧按键对手机200的中框120的尺寸造成影响，一般使用虚拟侧按键代替物理侧按键的设计。然而，虚拟侧按键的灵敏度 较低，且虚拟侧按键容易发生失效，对用户的使用体验造成较大影响。
或者，现有技术中，为了实现按键的内键和外键之间的连接，一般会在外键20朝向内键10的一面上预留封胶位置，因而，如图3所示，现有技术中的按键的外键20的宽度L1一般是大于内键10的功能部101的宽度L2，这样，按键的整体宽度至少为外键20的宽度，按键的整体宽度等于内键10的宽度(例如1.3mm)和两侧封胶宽度(例如0.2mm)之和，即按键的总体宽度大于1.5mm，而按键的宽度过大对中框120的尺寸有很大影响，从而也会对手机200的轻薄化造成影响。
基于此，本申请实施例提供一种按键，通过将内键设在外键的背面上，且外键在按键的宽度方向上的尺寸与内键的功能部的至少部分在按键的宽度方向上的尺寸相同，即外键的侧边缘与内键的功能部的至少部分的侧边缘相齐平，能够实现最大化减窄按键的整体宽度，这样能够减小按键在沿着电子设备的厚度方向上的尺寸，从而能够减小按键在中框上的设计尺寸，减小或消除对电子设备的中框的尺寸造成影响，进而有利于将中框在沿着电子设备的厚度方向上的尺寸减薄，以实现电子设备整体的轻薄化。另外，通过上述设置，还能够避免现有技术中采用虚拟化指纹识别按键时容易产生按键不灵敏甚至失效，对用户的使用体验造成较大影响的问题。
下面以具体的实施例为例，结合附图对该电子设备的具体结构进行介绍。
参照图4和图5所示，本申请实施例提供一种按键100，该按键100可以应用于电子设备(例如手机200)中，该按键100至少可以包括：内键10以及外键20，其中，外键20可以包括：按压面201以及背面202，按压面201与背面202相背，内键10设在外键20的背面202上。
其中，内键10可以为软胶键，即内键10所采用的材料可以为软胶材质。具体地，软胶可以是用塑料通过注塑形成﹐常温下手感较软，是一种材质表面硬度相对低的塑料。作为一种可选的实施方式，软胶可以为硅胶，例如有机硅胶等，有机硅胶是以硅-氧(Si-O)键为主链结构的，C-C键的键能为82.6千卡/克分子，Si-O键的键能在有机硅中为121千卡/克分子，所以有机硅胶的热稳定性高，高温下(或辐射照射)分子的化学键不断裂、不分解。有机硅胶不但可耐高温，而且也耐低温，可在一个很宽的温度范围内使用。无论是化学性能还是物理机械性能，随温度的变化都很小。
外键20可以为硬胶键，即外键20所采用的材料可以为硬胶材质。硬胶是日常用品的塑胶物料之一，是一种塑胶物质，质料硬，不耐用，容易出裂隙。含三到四成硫。
具体地，内键10至少可以包括：功能部101，其中，功能部101用于与电路板130上的音量控制器件(图中未示出)相配合，以实现功能部101与相接触时，功能部101能够触发音量控制器件的音量调节功能。
可以理解的是，电路板130上一般设置有多个电子元器件，电路板130可以为电子元器件供电，例如电路板130上一般会设置有音量控制器件、处理器、天线模块、蓝牙模块、无线保真(Wireless-Fidelity，WiFi)模块、全球定位系统(Global Positioning System，GPS)模块、电源以及充电模块或摄像操作模块等。
在本申请实施例中，外键20在按键100的宽度方向上的尺寸可以与功能部101的至少部分在按键100的宽度方向上的尺寸相同。参见图5所示，外键的宽度L3与功能部的宽度L4相同。
这样，能够实现最大化减窄按键100的整体宽度，能够减小按键100在沿着电子设备的厚度方向上的尺寸，从而能够减小按键100在中框上的设计尺寸，减小或消除对电子设备的中框的尺寸造成影响，进而有利于将中框在沿着电子设备的厚度方向上的尺寸减薄，以实现电子设备整体的轻薄化。
另外，通过上述设置，还能够避免现有技术中采用虚拟化指纹识别按键100时容易产生按键100不灵敏甚至失效，对用户的使用体验造成较大影响的问题。
需要说明的是，在本申请实施例中，内键10的功能部101的截面可以为矩形、圆形、椭圆形或三角形等，本申请实施例对此并不加以限定，也不限于上述示例。其中，当内键10的功能部101的截面为矩形时，内键10的功能部101的截面可以为直角矩形也可以是如图5所示的圆角矩形。
在本申请实施例中，外键20可以与一个内键10相配合，这样按压外键20即可触发内键10，此时，外键20与一个内键10所形成的按键100可以为开关机键。
或者，在一些实施例中，参见图4所示，外键20可以与两个内键10相配合，两个内键10中的其中一者与外键20的一端相配合，两个内键10中的另一者与外键20的另一端相配合，这样按压外键20的两端能够分别触发两个内键10，此时，外键20与两个内键10所形成的按键100可以为音量键。具体地，两个内键10中的其中一者与外键20相配合作为音量加键，两个内键10中的另一者与外键20相配合作为音量减键。
可以理解的是，内键10与电路板130之间可以通过柔性电路板(图中未示出)实现电连接。在一些实施例中，可以是内键10的功能部101通过柔性电路板与电路板130之间实现电连接。
另外，在本申请实施例中，内键10靠近外键20的一端的至少部分可以嵌设在外键20的内部。具体地，可以是内键10靠近外键20的一端的部分嵌设在外键20的内部，也可以是内键10靠近外键20的一端的全部嵌设在外键20的内部。
内键10靠近外键20的一端的部分嵌设在外键20的内部，能够确保内键10与外键20配合时的可靠性能，避免内键10与外键20之间发生分离。内键10靠近外键20的一端的全部嵌设在外键20的内部，相对于部分嵌设，能够在更大程度上确保内键10与外键20配合时的可靠性能，进一步避免内键10与外键20之间发生分离。
在本申请实施例中，外键20在按键100的长度方向上的其中一个外侧壁可以与功能部101在按键100的长度方向上的其中一个外侧壁相齐平，外键20在按键100的长度方向上的另一个外侧壁可以与功能部101在按键100的长度方向上的另一个外侧壁相齐平。
外键20在按键100的长度方向上的两个外侧壁与内键10的功能部101在按键100的长度方向上的两个外侧壁相互齐平，能够确保外键20在按键100的宽度方向的尺寸与内键10的功能部101在按键100的宽度方向上的尺寸相同，这样能够实现最大化减窄按键100的整体宽度，从而能够减小按键100在沿着电子设备的厚度方向上的尺寸，进而能够减小按键100在中框上的设计尺寸。
示例性地，参见图6所示，外键20在按键100的长度方向上的两个外侧壁(即外键的外侧壁203)与内键10的功能部101在按键100的长度方向上的两个外侧壁(即 功能部的外侧壁1011)相互齐平。
参照图5或图6所示，内键10还可以包括：第一连接部102，其中，第一连接部102的一端与功能部101相连，第一连接部102的另一端与手机200的中框120相连。通过设置第一连接部102，能够实现内键10与中框120的相连。
需要说明的是，在本申请实施例中，第一连接部102可以为如图5或图6所示的挂耳，挂耳的一端可以与功能部101相连，挂耳的另一端可以与手机200的中框120相连。具体地，挂耳可以为软胶材质。挂耳与中框120相连，能够实现内键10与中框120的相连，进而能够实现按键100与中框120的相固定。
继续参照图5或图6所示，内键10还可以包括：第二连接部103，其中，第二连接部103的一端与功能部101相连，第二连接部103的另一端与第一连接部102相连。第二连接部103能够增加功能部101与第一连接部102之间的连接稳固性。
在本申请实施例中，第二连接部103在按键100的宽度方向上的尺寸可以小于或者等于功能部101在按键100的宽度方向上的尺寸。这样，能够保证功能部101作为内键10中在按键100的宽度方向上尺寸最大的单元，从而避免第二连接部103进一步增大内键10的整体宽度。
另外，在一些实施例中，功能部101在按键100的长度方向上的外侧壁与外键20在按键100的长度方向上的外侧壁之间的距离可以小于第二连接部103在按键100的长度方向上的外侧壁与外键20在按键100的长度方向上的外侧壁之间的距离。
也就是说，第二连接部103在按键100的宽度方向上的尺寸可以小于功能部101在按键100的宽度方向上的尺寸，这样，当功能部101在按键100的长度方向上的外侧壁(即功能部的外侧壁1011)与外键20在按键100的长度方向上的外侧壁(即外键的外侧壁203)相互齐平时，能够使得第二连接部103在按键100的长度方向上的外侧壁与外键20在按键100的长度方向上的外侧壁之间在按键100的宽度方向上存在间隔，该间隔会在外键20朝向内键10的一面上形成用于封胶的台阶面(即裸露区域2021)。
示例性地，如图5所示，第二连接部的外侧壁1031与外键的外侧壁203之间在按键100的宽度方向上的距离大于功能部的外侧壁1011与外键的外侧壁203之间在按键100的宽度方向上的距离。
在本申请实施例中，第二连接部103靠近功能部101的一端在按键100的长度方向上的至少一个外侧壁上可以设有至少一个缺口1032，以使外键20与第一连接部102相对位置处的至少部分背面202裸露。外键20与第一连接部102相对位置处的至少部分背面202裸露，外键20的背面202所裸露的区域(即裸露区域2021)即可用于封胶。
现有技术中将按键的外键20的宽度设置为大于按键的内键10的宽度，即在外键20朝向内键10的一面上预留封胶位置，是为了在外键20和内键10的功能部101之间的间隔中做封胶，而本方案将封胶位置移至第二连接部103与外键20之间，这样无需在功能部101的旁边预留做封胶的间距，因而可将外键20的宽度设置为与内键10的功能部101的宽度相同。
需要说明的是，在本申请实施例中，缺口的底壁1033可以为倾斜面。通过将缺口 的底壁1033设置为倾斜面，能够增加封胶工艺的可行性。
另外，可以理解的是，在本申请实施例中，外键20在按键100的宽度方向上的尺寸(即外键的宽度L3)可以小于1.5mm。例如，外键20在按键100的宽度方向上的尺寸可以为1.45mm、1.4mm、1.35mm、或1.3mm等，本申请实施例对此并不加以限定。
另外，内键10的功能部101在按键100的宽度方向上的尺寸(即功能部的宽度L4)可以小于1.5mm。例如，内键10的功能部101在按键100的宽度方向上的尺寸可以为1.45mm、1.4mm、1.35mm、或1.3mm等，本申请实施例对此并不加以限定。
这里需要说明的是，本申请涉及的数值和数值范围为近似值，受制造工艺的影响，可能会存在一定范围的误差，这部分误差本领域技术人员可以认为忽略不计。
需要说明的是，在本申请实施例中，按键100可以为音量键，按键100也可以为开关机键。或者，电子设备200内可以具有两个按键100(参见图2所示)，两个按键100中的其中一个按键100可以为开关机键，两个按键100中另一个按键100可以为音量键，该音量键的两端可以分别作为音量加键和音量减键。
或者，电子设备200内可以具有三个按键100，三个按键100中的其中一个按键100可以为开关机键，三个按键100中另一个按键100可以为音量加键，三个按键100中又一个按键100可以为音量减键。
在本申请实施例中，按键100还可以包括：至少一个按键开关(图中未示出)，按键开关可以与柔性电路板电连接，而且，按键开关与按键100配合。具体地，按键开关与按键100的内键10相配合。这样，按压或触摸按键100即可触发按键开关，而且，按键开关与柔性电路板电连接，柔性电路板与电路板130电连接，这样能够确保按键开关与电路板130之间电连接，从而确保按键100的使用性能。
另外，可以理解的是，在本申请实施例中，按键开关的数量可以为三个，三个按键开关分别为第一按键开关、第二按键开关以及第三按键开关，其中，第一按键开关、第二按键开关和第三按键开关可以均与柔性电路板电连接，且第一按键开关、第二按键开关和第三按键开关均与按键100相配合。
第一按键开关、第二按键开关以及第三按键开关与柔性电路板电连接，柔性电路板与电路板电连接，能够确保第一按键开关、第二按键开关以及第三按键开关与电路板之间的电连接，从而确保第一按键开关、第二按键开关以及第三按键开关的使用性能。
其中，第一按键开关用于控制手机200的开启或关闭，第二按键开关和第三按键开关用于控制手机200的音量大小，具体地，第二按键开关可以用于调大手机200的音量，第三按键开关可以用于调小手机200的音量。
在一些实施例中，手机200中按键100的数量可以为两个，两个按键100中的其中一个按键100可以为电源开关键，两个按键100中的另一个按键100可以为音量键。其中，电源开关键可以与第一按键开关相对，音量键的两端可以分别与第二按键开关和第三按键开关相对，具体地，音量键的两端可以分别作为音量加键和音量减键，音量加键与第二按键开关相对，音量减键与第三按键开关相对。
或者，在其它的一些实施例中，手机200中按键100的数量可以为三个，三个按 键100中的其中一个按键100可以为电源开关键，三个按键100中的另外两个按键100可以分别为音量键。其中，电源开关键可以与第一按键开关相对，两个音量键可以分别与第一按键开关和第二按键开关相对，具体地，两个音量键可以分别为音量加键和音量减键，其中，音量加键与第二按键开关相对，音量减键与第三按键开关相对。
在本申请实施例中，边框122上可以开设至少两个开口1225(参见图1所示)，按键100可以位于开口1225处。示例性地，参见图1和图2所示，两个按键100可以穿设在两个开口1225中，且两个按键100背离边框122的一端可以裸露设置。
作为一种可选的实施方式，左侧边1223和右侧边1224的其中一者上可以设置开口1225，以边框122上开设有两个开口1225为例，开口1225可以是位于左侧边1223上，也可以是位于右侧边1224上，或者，两个开口1225中的其中一个开口1225可以位于左侧边1223上，两个开口1225中的另一个开口1225可以位于右侧边1224上，本申请实施例对此并不加以限定，也不限于上述示例。
当然，在其它的一些实施例中，边框122上也可以设置三个开口1225，可以是三个开口1225均位于左侧边1223上，也可以是三个开口1225均位于右侧边1224上，或者，还可以是三个开口1225中的其中一个开口1225位于左侧边1223上，三个开口1225中的另两个开口1225位于右侧边1224上，本申请实施例对此并不加以限定，也不限于上述示例。
