Description

盲人触控组件及盲人用触控设备 技术领域
本实用新型属于触控技术领域，更具体地说，是涉及一种盲人触控组件及盲人用触控设备。
 背景技术
随着科学技术的发展，电子设备的应用越来越广泛，使用手机网上支付，通过手机或平板电脑与家人朋友进行电话沟通，这些都已经是人们生活中必不可少的一部分。但是，对于盲人来说，由于眼睛看不到，电子设备根本无法应用，特别是采用触摸屏的POS机、手机及平板电脑，因为触摸屏的表面是平整光滑的，盲人无法用手指进行感知，因此根本无法操作，从而导致盲人在很多情况下与现实脱轨，生活感到自卑和无奈。
 技术问题
本实用新型的目的在于提供一种盲人触控组件，以解决现有技术中存在的具有触摸屏的设备因触摸屏表面平整导致盲人无法用手指感知、无法进行操作的技术问题。
 技术解决方案
为实现上述目的，本实用新型采用的技术方案是：提供了一种盲人触控组件，包括电路板，与所述电路板电连接的显示屏，以及与所述电路板电连接并贴设于所述显示屏上的触摸屏，所述触摸屏上贴设有用于保护所述触摸屏的屏保膜，所述屏保膜上设有多个手指可触摸感知的键框部，至少一所述键框部中设有手指可触摸感知的盲文部。
优选地，所述屏保膜为钢化贴膜或者塑料贴膜。
优选地，所述屏保膜的长度大于或等于所述显示屏的长度，所述屏保膜的宽度大于或等于所述触摸屏的宽度。
进一步地，所述键框部的位置与所述显示屏上显示的键框区的位置相对应，所述盲文部的位置与所述显示屏上显示的数字区的位置相对应。
进一步地，所述盲人触控组件还包括与所述电路板电连接并用于发出提示语言的语音模块。
优选地，所述屏保膜上开设有相互交错的沟槽，所述键框部为所述沟槽围合形成的块区域，所述盲文部凸设于所述块区域上。
优选地，所述键框部凸设于所述屏保膜上，所述盲文部凸设于所述键框部上。
优选地，所述键框部为凹设于所述屏保膜上的凹槽，所述盲文部凸设于所述凹槽中。
本实用新型还提供了一种盲人用触控设备，包括后壳，以及与所述后壳连接的中框，还包括上述盲人触控组件，所述电路板安装于所述后壳与所述中框之间，所述显示屏、所述触摸屏及所述屏保膜依次安装于所述中框上。
进一步地，所述盲人用触控设备还包括与所述电路板电连接的支付模块，与所述电路板电连接的按键，与所述电路板电连接的USB座，以及与所述电路板电连接的TF卡座。
 有益效果
本实用新型提供的盲人触控组件的有益效果在于：与现有技术相比，本实用新型的盲人触控组件通过屏保膜的设置，且在屏保膜上设有手指可触摸感知的键框部，以及在键框部中设有手指可触摸感知的盲文部，这样，盲人使用时，只要通过手指在屏保膜上感知键框部的位置，然后在键框部中感知盲文部的位置，从而找到正确的数字并进行触摸输入，进而使得盲人触控组件可供盲人操作。此外，本实用新型的盲人用触控设备通过上述盲人触控组件的设计，使得其可供盲人使用。

实施例一：
请一并参阅图1至图5，现对本实用新型提供的盲人触控组件进行说明。该盲人触控组件包括电路板9、显示屏3、触摸屏2及屏保膜1，显示屏3与电路板9电连接并用于显示图像及视频，触摸屏2与电路板9电连接并贴设于显示屏3上，触摸屏2用于手指触摸输入控制指令，屏保膜1贴设于触摸屏2上并用于保护触摸屏2，请参阅图2，屏保膜1上设有10个手指可触摸感知的键框部4，其中有4个键框部4中设有手指可触摸感知的盲文部5，4个盲文部5分别为位于最下方的X部、<部及O部，以及位于5字区的圆点部，盲人可通过这4个盲文部5来判断其他数字的位置。在本实用新型实施例中，上述触摸屏2及屏保膜1均呈薄板状，且均为透明件，即透过屏保膜1及触摸屏2可以清晰的看到显示屏3显示的内容。此外，在本实施例中，上述屏保膜1上设有10个键框部4，且其中有4个键框部4上设有盲文部5，当然，本实用新型的其他实施例中，根据实际情况及具体要求，上述屏保膜1上也可以设置设有9个、12个、15个键框部4，同时有2个、3个或5个键框部上设有盲文部5，且盲文部5的位置也可以根据需要进行调整，此处不做唯一限定。
本实用新型提供的盲人触控组件，与现有技术相比，本实用新型的盲人触控组件通过屏保膜1的设置，且在屏保膜1上设有手指可触摸感知的键框部4，以及在键框部4中设有手指可触摸感知的盲文部5，如本实施例中的，在最下方设置X部、<部及O部，然后在5字区设置圆点部，这样，盲人使用时，只要通过手指在屏保膜1上感知键框部4的位置，然后在键框部4中感知X部、<部、O部及圆点部的位置，从而判断出其他数字的位置并进行触摸输入，进而使得盲人触控组件可供盲人操作。
优选地，作为本实用新型提供的盲人触控组件的一种具体实施方式，上述屏保膜1优选为钢化贴膜，这种保护膜的厚度只有0.1毫米，能将原有的屏幕面完全覆盖，防止受到外力的损害及划伤，更增加了冲击吸收性，比PET膜的标准高5倍，且不会影响屏幕的视频效果。本实施例通过选用钢化贴膜作为屏保膜1，可以使得该盲人触控组件的使用强度及使用寿命更强，更适合盲人使用。
优选地，在本实用新型的其他实施例中，根据实际情况及具体要求，上述屏保膜1也可选用塑料贴膜，具体的为采用透明PET材质制成的塑料贴膜，PET材料质地比较硬，比较耐刮，且其制作工艺简单，相对钢化贴膜成本大大降低。
优选地，请参阅图4，作为本实用新型提供的盲人触控组件的一种具体实施方式，上述屏保膜1的长度与触摸屏2的长度相等，屏保膜1的宽度与触摸屏2的宽度相等，且屏保膜1的长度大于显示屏3的长度，屏保膜1的宽度大于显示屏3的宽度，在本实施例中，上述的长度均指图3中左右方向的长度，宽度均指图3中上下方向的宽度，这样，屏保膜1能够完全地将触摸屏2及显示屏3保护到，且显示屏3上显示的数字都能通过屏保膜1进行触控。当然，在本实用新型的其他实施例中，根据实际情况及具体要求，上述屏保膜1的长度也可以等于显示屏3的长度，屏保膜1的宽度也可以等于显示屏3的宽度，此处不做唯一限定。
进一步地，作为本实用新型提供的盲人触控组件的一种具体实施方式，请参阅图2，为显示屏3屏幕显示界面的一种实施例，对应的，上述键框部4的位置与显示屏3上显示的键框区31的位置相对应，盲文部5的位置与显示屏3上显示的数字区32的位置相对应，这样使得显示屏3、触摸屏2及屏保膜1三者联系在一样，通过显示屏3上显示出需要操作的界面，然后通过屏保膜1输入控制指令，最后通过触摸屏2实现触控。
进一步地，作为本实用新型提供的盲人触控组件的一种具体实施方式，上述盲人触控组件还包括语音模块，语音模块与电路板9电连接，语音模块用于在盲人使用时，发出提示语音以提供盲人接下来该如何操作，同时，在盲人输入数字时语音报出该数字，从而防止盲人输错数字。通过语音模块的设置，使得该盲人触控组件的功能更加的齐全，更适合盲人使用。
优选地，请参阅图1及图5，作为本实用新型提供的盲人触控组件的一种具体实施方式，上述屏保膜1上开设有相互交错的沟槽11，键框部4为沟槽11围合形成的块区域，盲文部5凸设于块区域上，本实施例可以通过一体成型加工出屏保膜1及盲文部5，然后通过镭雕工艺在屏保膜1上根据键框部4的尺寸雕刻出具有触感的沟槽11，从而能够达到盲人识别的目的。
本实用新型还提供了一种盲人用触控设备，请参阅图1、图2及图4，该盲人用触控设备包括后壳7、中框6及上述盲人触控组件，后壳7与中框6连接并围合形成有安装腔，电路板9安装于后壳7与中框6之间并位于安装腔中，显示屏3、触摸屏2及屏保膜1依次安装于中框6上。在本实施例中，上述盲人用触控设备为盲人用POS机，其还包括与电路板9电连接的支付模块，这样，盲人就可以通过该盲人用POS机进行收营工作。当然，在本实用新型的其他实施例中，上述盲人用触控设备也可以为盲人用手机及平板电脑等，只要是具有触摸屏2的机器都可以，此处不做唯一限定。
进一步地，请参阅图1及图2，作为本实用新型提供的盲人用触控设备的一种具体实施方式，上述盲人用触控设备还包括与电路板9电连接的支付模块，与电路板9电连接的按键8，与电路板9电连接的USB座10，以及与电路板9电连接的TF卡座，支付模块用于支付交易，按键8用于开启该盲人用触控设备或者调节音量，USB座10用于为盲人用触控设备充电，TF卡座用于向盲人用触控设备中输入各种软件数据。
实施例二：
本实施例的盲人触控组件与实施例一中的盲人触控组件基本相同，其区别在于：上述键框部4凸设于屏保膜1上，盲文部5凸设于键框部4上。本实施例通过将键框部4设计成凸设于屏保膜1上以供盲人识别，同时将盲文部5设计成凸设于键框部4上以供盲人识别，即上述屏保膜1、键框部4及盲文部5呈阶梯状，其手指触摸感高，适合盲人使用。在本实用新型实施例中，上述屏保膜1、键框部4及盲文部5通过一个模具一体成型，其加工工艺简单成本低。
实施例三：
本实施例的盲人触控组件与实施例一中的盲人触控组件基本相同，其区别在于：上述键框部4为凹设于屏保膜1上凹槽，盲文部5凸设于凹槽中，本实施例通过凹槽来识别键框部4，同时通过凸设于凹槽中的盲文部5来供盲人识别，由于键框部4的尺寸相对盲文部5尺寸较大，则凹槽尺寸相对盲文部5尺寸较大，因此凹槽容易识别，适合盲人使用。在本实施例中，上述盲文部5的顶面与屏保膜1的顶面，如此，只需要在屏保膜1上将键框部4区域内除去盲文部5之外的部分均挖除即可，其加工工艺也较简单，加工成本低。
实施例四：
本实施例的盲人触控组件与实施例一中的盲人触控组件基本相同，其区别在于：上述键框部4为屏保膜1上打磨出的粗糙区，盲文部5凸设于粗糙区上，本实施例可以通过一体成型加工出屏保膜1及盲文部5，然后通过磨砂工艺在屏保膜1上根据安装键框部4的尺寸打磨出具有触感的粗糙区，同样能够达到盲人识别的目的。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
