Description

一种非居边投影一体式电子触控白板
技术领域
本实用新型涉及一种电子白板，尤其涉及一种非居边投影一体式电子触控白板。
背景技术
电子白板广泛应用于会议室、教室等。由于受到投影范围限制及电子白板结构影响，在教育领域应用常受到结构制约。以前市场上普遍做法是将电子白板的在周围采用拼装方式加配绿板用于书写，这种方式结构繁琐、使用不便。
为克服上述问题，目前是将电子白板书写区和触控集成在一块面板上，可以在该电子白板上进行手写，又可以进行触控翻看电脑主机PC内的资料，供上课、会议时使用，成为新型的多媒体设备。这种结构不但结构简单、使用方便且增加产品美感。目前这些集合触控区与手写区为一体的电子白板的触控区在手写区的一侧，由于目前的课件很多都是采用PPT形式，很少利用到手写区，甚至有些老师/会议组织者在授课、交流时不用手写区，如果将触控区设置在电子白板的一侧，坐在电子白板前方的另一侧的同学/与会人员无法看清触控区的课件。
实用新型内容
为克服上述缺点，本实用新型的目的在于提供一种能使电子白板前排的同学/与会人员能看清电子白板上的触控区课件的非居边投影一体式电子触控白板。
为了达到以上目的，本实用新型采用的技术方案是：一种非居边投影一体式电子触控白板,包括电子白板、红外摄像头、触控主板、电脑主机PC，所述电子白板的四周设置有边框，所述边框的内侧壁上设置有光学反射条，所述电子白板与电脑主机PC连接，所述红外摄像头通过触控主板与电脑主机连接，所述电脑主机PC将所述电子白板分隔呈左手写区、右手写区以及中间触控区，所述红外摄像头设置有两个，两个所述红外摄像头设置在中间触控区上边框和下边框的同一端，所述红外摄像头朝向所述中间触控区。
本实用新型非居边投影一体式电子触控白板的有益效果是，将中间触控区设置在电子白板的中间，在使用过程中，使用到中间触控区的几率远远大于使用到左、右手写区的几率，本方案中将中间触控区设置在电子白板的中间，使得在电子白板前面的学生/与会人员都能看清电子白板的触控区的课件资料，解决了因触控区设置在电子白板一侧，影响电子白板前方另一侧学生/与会人员看课件的问题；此外，手写区位于电子白板的两端，可以同时进行书写。
优选地，所述电脑主机PC内置在电子白板内。在电子白板本体内，在搬运、安装过程中，不易破坏电脑主机。
优选地，所述中间触控区的上方还设置有超短焦投影仪，所述超短焦投影仪通过HDMI线与电脑主机PC连接。超短焦投影仪设置在中间触控区的电子白板本体上方，继而解决有物体阻碍投影的光线，导致无法完成投影的问题。
优选地，所述HDMI线与电脑主机PC之间通过HDMI转接板连接，所述HDMI转接板内置在电子白板内。在电子白板本体内，在搬运、安装过程中，不易破坏电脑主机。
优选地，所述中间触控区与触控主板连接，所述中间触控区的触控启闭由触控主板驱动。可通过开关将电子白板的中间触控区关闭，进行整个白板面白板笔手写书写。
附图说明
图1为实施例一的主视图；
图2为实施例二的主视图。
图中：
1-边框；2-光学反射条；3-电子白板；31-左手写区；32-右手写区；33-中间触控区；4-触控主板；5-红外摄像头；6-超短焦投影仪；7-电脑主机PC。
具体实施方式
下面结合附图对本实用新型的较佳实施例进行详细阐述，以使本实用新型的优点和特征能更易于被本领域技术人员理解，从而对本实用新型的保护范围做出更为清楚明确的界定。
参见附图1所示，实施例一的一种非居边投影一体式电子触控白板,包括电子白板3、红外摄像头5、触控主板4、电脑主机PC 7、超短焦投影仪6，电子白板3的四周设置有边框1，边框1的内侧壁上设置有光学反射条2，电子白板3与电脑主机PC 7连接，电脑主机PC7内置在电子白板3内，红外摄像头5通过触控主板4与电脑主机PC 7连接，超短焦投影仪6设置在中间触控区33的上方，超短焦投影仪6通过HDMI线与电脑主机PC7连接，通过HDMI线可以进行电子白板的电讯输出，进行人机互动操作，HDMI线与电脑主机PC7之间通过HDMI转接板连接，所述HDMI转接板内置在电子白板3内，开关与电脑主机PC 7连接。电脑主机PC 7将电子白板3分隔呈左手写区31、右手写区32以及中间触控区33，中间触控区33通过触控程式坐标进行限定，其位于电子白板3的正中间位置、中间偏左或中间偏右的位置。所述红外摄像头可向左、右投射，并可以实现中间任意大小区域触控。中间触控区33设置在红外投射区内，所述红外投射区为红外摄像头投射方向至光学反射条所在的区域，包括向左投射覆盖左手写区31和中间触控区33，或向右投射覆盖右手写区32和中间触控区33，中间触控区33可通过程式任意调整大小。红外摄像头5设置有两个，两个红外摄像头5设置在中间触控区33上边框和下边框的同一端，在本实施例中，两个红外摄像头5设置在上边框和下边框的右端，红外摄像头5朝向中间触控区33。中间触控区33用以实现白板触控能，左手写区31、右手写区32可以同时进行白板笔手写，中间触控区33与触控主板4连接，中间触控区33的触控启闭由触控主板4驱动，也可关闭通过开关关闭白板触控能，进行整个白板面白板笔手写书写。
红外触控的原理属于现有技术，每个红外摄像头内具有LED光源(图中未示出)，LED光源射向对面的光学反射条2，经光学反射条2将LED发射的红外光反射回红外摄像头5，若没有物体在中间触控区33的电子白板上进行操作时，红外摄像头5会接收到射向光学反射条2上反射的反射光，一旦有物体在中间触控区33的电子白板上进行操作时，红外摄像头5的LED光源无法到达光学反射条2上，继而红外摄像头5则观测不到反射的反射光，通过该原理，两个红外摄像头5将观测到的信号传送至触控主板4，触控主板4与电脑主机PC 7连接，触控主板4通过电脑主机PC 7计算触控点在光学反射条2的数据，得到触控坐标X,Y。
实施例二，如图2所示，与实施例一不同的是，两个红外摄像头5设置在中间触控区33上边框和下边框的左端。
上实施方式只为说明本实用新型的技术构思及特点，其目的在于让熟悉此项技术的人了解本实用新型的内容并加以实施，并不能以此限制本实用新型的保护范围，凡根据本实用新型精神实质所做的等效变化或修饰，都应涵盖在本实用新型的保护范围内。
