压力触控板和电子设备 技术领域
本申请实施例涉及电子技术领域，尤其涉及一种压力触控板和电子设备。
背景技术
对于具有触觉反馈功能的压力触控板来说，触觉反馈部件需要放置在触摸面板的下方正中心位置，才能确保实际体验时，手指接触的触摸面板的任一区域都能感受到相同的震动体验。
但在实际整机堆叠设计过程中，触控板正下方多为电池组件、主板等部件。电池电芯在充放电过程中会鼓起，整机堆叠亦无过多安全空间，避免触觉反馈部件的金属客体接触到电芯，导致刺穿引起安全事故，通常情况下会将触觉反馈部件摆放位置偏置。
触觉反馈部件偏置后，则产生了震动不一致的问题。为此，如何平衡压力触控板的震动，以提高用户体验，成为需要解决的问题。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。
基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
下面将结合附图详细的对本申请实施例的内容进行描述，以使本领域技术人员能够更加详细的了解本申请的内容。
触控板是一种应用于电子设备的控制屏幕光标的输入装置。触控板通过检测用户手指在面 板区域操作时的微小电容变化，得到高分辨率手指坐标等触控信息，以精确控制屏幕光标进行移动、点击。通常触控板背面也配置了单按键，通过检测按键的行为实现了传统的鼠标左键和右键的功能。
为了提升触控板的操作便捷性，压力触控板渐渐成为一种新趋势。压力触控板是指取消了常规触控板的物理按键，并增加了压力感应和震动反馈功能。
电子设备的压力触控板通常由触摸面板、压力传感器、触觉反馈部件等组成。其中触觉反馈部件需放置在触摸面板下方正中心位置，才能确保实际体验时，手指接触的触摸面板的任一区域都能感受到相同的震动体验。
但实际整机堆叠设计过程中，压力触控板正下方多为电池组件、主板。电池电芯充放电过程中会鼓起，整机堆叠亦无过多安全空间，避免触觉反馈部件的金属客体接触到电芯，导致刺穿引起安全事故，通常情况下会将触觉反馈部件摆放位置偏置。例如，触觉反馈部件可摆放在电池封装的塑胶框与触控板之间、也可摆放在主板与触控板之间。
触觉反馈部件偏置后，则随之产生震动不一致的问题。
有鉴于此，本申请实施例提供了一种压力触控板，有利于解决触觉反馈部件偏置后震动不一致的问题。
应理解，本申请实施例的技术方案可以应用于各种电子设备。
例如，智能手机、笔记本电脑、平板电脑、游戏设备等便携式或移动计算设备，以及电子数据库、汽车、银行自动柜员机(Automated Teller Machine，ATM)等其他电子设备。但本申请实施例对此并不限定。
图1示出了本申请一实施例的压力触控板100的结构爆炸图。该压力触控板100可以适用于电子设备。如图1所示，该压力触控板包括：触摸面板110、压力传感器120、触摸控制器130、支撑板140以及触觉反馈部件150。
压力传感器120设置在触摸面板110的下方，用于在手指按压压力触控板100时发生形变，并输出相应的压力感应信号；压力传感器120可以是压阻式压力传感器，例如，压力传感器120为应变式压力传感器。如图1所示，该压力传感器120可以设置在支撑板140与触摸面板110之间。
支撑板140设置于触摸面板110的下方，支撑板140包括两个柔性连接臂141和紧固区142，紧固区142设有螺母固定孔146，支撑板140通过两个柔性连接臂141与触摸面板110固定连接，并通过螺母固定孔146与电子设备的机壳固定连接。两个柔性连接臂141与紧固区142连接并且该两个柔性连接臂分别位于触觉反馈部件150的两侧，两个柔性连接臂141包括第一柔性连接臂1411和第二柔性连接臂1412，例如，在第一方向X上，第一柔性连接臂1411位于触觉反馈部件150的左侧，第二柔性连接臂1412位于触觉反馈部件150的右侧。支撑板140具有一定强度，不仅用于支撑触摸面板110，还用于将压力触控板100与电子设备进行固定安装。
触觉反馈部件150安装在触摸面板110的下方，触觉反馈部件150的安装位置到压力触控板100的一条长边的距离大于触觉反馈部件150的安装位置到压力触控板100的另一条长边的 距离，具体地，该触觉反馈部件150的安装位置到压力触控板100的两条短边的距离近似相等，该近似相等为允许有一定的误差存在，并且触觉反馈部件150的安装位置到压力触控板100的两条长边的距离不相等。触觉反馈部件150与触摸控制器130进行电性连接，用于响应所述手指施加的压力大小进行震动反馈。本申请实施例中的触觉反馈部件150是基于压力传感器120检测的压力信号向用户提供震动反馈。
需要说明的是，在本申请中，第一方向X为压力触控板100的长边方向，第二方向Y为压力触控板100的短边方向。
触摸控制器130安装固定在触摸面板110的下表面并与压力传感器120进行电性连接，用于确定手指在压力触控板100的触摸位置，以及从压力传感器120接收压力感应信号以确定手指施加的压力大小；触摸控制器130可以电性连接至触摸电极层和压力传感器120，其一方面用于向触摸电极层提供驱动信号进行电容式触摸检测；另一方面用于在手指按压压力触控板100时接收触摸电极层输出的触摸感应信号和压力传感器120输出的压力感应信号，并基于上述触摸感应信号和压力感应信号确定手指位置信息和手指施加的压力大小。触摸控制器130还可以连接至触觉反馈部件150，用于响应检测到的压力大小并驱动触觉反馈部件150进行震动反馈。在具体实施例中，触摸控制器130可以是集成压力检测和触摸位置检测的触控芯片，也可以是包括两个分离设置的用于检测压力的压力检测芯片和用于检测触摸位置的触控芯片。
因此，本申请实施例的压力触控板，通过支撑板140的紧固区142和两个柔性连接臂141一体化连接，可以简化压力触控板的组装工艺，并且在触觉反馈部件150震动时，通过两个柔性连接臂141的相对位移来传递震动，有利于触觉反馈部件150所产生的震动均匀地分布在压力触控板的各个位置，从而可以解决触觉反馈部件150偏置时的震动不一致问题，提高用户的震动体验。
如图1-3所示，支撑板140的两个柔性连接臂141分别到触觉反馈部件150的垂直距离相等，即第一柔性连接臂1411到触觉反馈部件150的垂直距离与第二柔性连接臂1412到触觉反馈部件150的垂直距离近似相等，该近似相等为允许有一定的误差存在。两个柔性连接臂141沿第二方向Y延伸，触觉反馈部件150沿第一方向X震动，也就是说，两个柔性连接臂141的延伸方向垂直于触觉反馈部件150的震动方向。
本实施例中的两个柔性连接臂141既有约束或传递震动的关系，又可以有一定程度的相对位移。即当触觉反馈部件150震动时，在与触觉反馈部件150震动方向平行的方向上，两个柔性连接臂141存在微观运动，从而可以平衡触觉反馈部件150的震动。
支撑板140中的两个柔性连接臂141分别与触摸面板110之间包括间隙，两个柔性连接臂141用于平衡触觉反馈部件150产生的震动。通过两个柔性连接臂141与触摸面板110之间的间隙，为手指按压压力触控板提供了形变空间。当触觉反馈部件150震动时，在与触觉反馈部件150震动方向平行的方向上，两个柔性连接臂141存在微观运动，从而可以平衡触觉反馈部件150的震动。
可选地，如图3所示，支撑板140包括两个柔性连接臂141和紧固区142，支撑板140通过两个柔性连接臂141与触摸面板110柔性连接。两个柔性连接臂141的一端与紧固区142连 接，紧固区142可以用于支撑触摸面板110，还可以将支撑板140通过紧固区142的螺母固定孔146连接固定至电子设备的机壳。
如图3所示，紧固区142设置于支撑板140的四周，紧固区142包括两个长边区域1421和两个短边区域1422，紧固区142的两个长边区域1421和两个短边区域1422围合形成开窗区域143，两个柔性连接臂141设置于开窗区域143内。
本申请实施例通过支撑板140的紧固区142内侧形成开窗区域143，减轻了支撑板的重量，使得整个压力触控板更加轻巧，将两个柔性连接臂设置于开窗区域内，能够给柔性连接臂提供位移空间以平衡触觉反馈部件产生的震动。
可选地，该两个柔性连接臂141设置于开窗区域143内并且两个柔性连接臂141沿触觉反馈部件150的安装位置在第二方向Y上的中心线对称地分布在触觉反馈部件150的两侧，两个柔性连接臂141的延伸方向垂直于触觉反馈部件150的震动方向。例如，如图3所示，两个柔性连接臂141沿着触觉反馈部件150的安装位置在第二方向Y上的中心线对称地设置在开窗区域143内，并且两个柔性连接臂141与支撑板140同一长边的紧固区连接。触觉反馈部件150在第一方向X上震动，两个柔性连接臂141在第二方向Y上延伸。第一柔性连接臂1411与第二柔性连接臂1412沿着支撑板140在第二方向Y上的中心线对称，即支撑板140沿支撑板140在第二方向Y上的中心线对称之后，第一柔性连接臂1411和第二柔性连接臂1412能够完全重合。
触觉反馈部件在第一方向X上震动，能够给压力触控板以外的部件提供安全空间，还能给用户带来清脆利落的震动体验。由于两个柔性连接臂141沿触觉反馈部件150的安装位置在第二方向Y上的中心线对称地分布在触觉反馈部件150的两侧，并且两个柔性连接臂141的延伸方向垂直于触觉反馈部件的震动方向，能够使得触觉反馈部件150所产生的震动均匀分布在压力触控板的各个位置，从而解决触觉反馈部件偏置时的震动不一致问题，提高用户的震动体验。
图4为图3中的第一柔性连接臂1411的示意性放大图。
可选地，如图3结合图4所示，两个柔性连接臂141包括第一柔性连接臂1411和第二柔性连接臂1412，第一柔性连接臂1411包括主体部14111和连接部14112；第二柔性连接臂1412包括主体部14121和连接部14112。也就是说，两个柔性连接臂141均包括主体部和连接部。在第一柔性连接臂1411中，主体部14111沿第二方向Y延伸，主体部14111的两端分别连接紧固区142的长边区域1421和连接部14112，并且连接部14112与触摸面板110固定连接。在第二柔性连接臂1412中，主体部14121沿第二方向Y延伸，主体部14121的两端分别连接紧固区142的长边区域1421和连接部14112，并且连接部14122与触摸面板110固定连接。应理解，本申请中的第一柔性连接臂1411的连接部14112是指第一柔性连接臂1411与触摸面板110连接的区域，第二柔性连接臂1412的连接部14122是指第二柔性连接臂1412与触摸面板110连接的区域。需要说明的是，如图3结合图4所示，紧固区142与两个柔性连接臂141的连接处分别形成了向开窗区域143延伸的三角区域1423，该三角区域1423分别与第一柔性连接臂1411的主体部14111和第二柔性连接臂1412的主体部14121一体化连接。
本申请实施例通过将两个柔性连接臂主体部的一端与紧固区一体化连接，两个柔性连接臂主体部的另一端所连接的连接部与触摸面板固定连接，能够简化触控板的组装工序，还能增强柔性连接臂的稳定性。
可选地，在本申请实施例中，主体部14111的长宽比大于或等于10:1。
本申请实施例通过将两个柔性连接臂主体部的长宽比设置为大于或等于10:1，能够有效地缩短触觉反馈部件的震动拖尾时间(或刹车时间)，使得震感体验更清脆。
如图4所示，第一柔性连接臂1411的主体部14111的长度为箭头1至箭头2的长度，第一柔性连接臂1411的主体部14111的宽度为箭头3至箭头4的长度。需要说明的是，第二柔性连接臂1412的结构和尺寸可以参考第一柔性连接臂1411的描述，为了简洁，此处不再赘述。

进一步地，为了保证两个柔性连接臂的主体部的长宽比大于或等于10:1，那么两个柔性连接臂的主体部的长度可以大于或等于15mm。
将两个柔性连接臂主体部设置为长条形，该长条形具体为均匀等宽等厚，可以使得两个柔性连接臂在平衡触觉反馈部件的震动时，震动传递更加均匀且柔性连接臂结构更加稳定，并且主体部的宽度大于或等于1.5mm，可以增强两个柔性连接臂与紧固区之间的连接强度，使得连接处不易折断。
可选地，如图2所示，第一柔性连接臂1411的连接部14112上设有柔性连接臂开孔14113，柔性连接臂开孔14113用于放置紧固件170，紧固件170将第一柔性连接臂1411与触摸面板110固定连接。同样地，第二柔性连接臂1412的连接部14122上设有柔性连接臂开孔14123。柔性连接臂开孔14123用于放置紧固件170，紧固件170将第二柔性连接臂1412与触摸面板110固定连接。
通过在柔性连接臂的连接部上设有柔性连接臂开孔，紧固件170穿过该柔性连接臂开孔，用于和触摸面板固定连接，增强了支撑板和触摸面板之间的紧固性，柔性连接臂主体部的一端所连接的连接部通过紧固件与触摸面板固定连接，柔性连接臂主体部的另一端与紧固区一体化连接，如此设置使得柔性连接臂更具有稳定性。
可选地，如图2所示，支撑板140设有压力传感器支撑区144，压力传感器支撑区144用于支撑压力传感器120，并且在压力触控板100承受压力时，带动压力传感器120一起发生形变。如图2所示，该压力传感器支撑区144例如为悬臂梁结构。
可选地，压力传感器支撑区144用于支撑压力传感器120，可以理解为压力传感器120固定于压力传感器支撑区144的上表面。需要理解的是，此处压力传感器支撑区144的上表面是指靠近触摸面板110的表面，压力传感器支撑区144的下表面是指背离触摸面板110的表面。
在实施例中，将用于支撑压力传感器的压力传感器支撑区与支撑触板的紧固区一体成型，不需要额外设置用于支撑压力传感器的弹性支架，减少了触控板的组件数量，进而简化了组装工序，节省了成本。
