Description

一体式便携投影电脑 技术领域
本发明属于笔记本电脑制造技术领域，具体说是一种一体式便携投影电脑。
 背景技术
现有笔记本电脑主要包括显示部分、电脑主机和键盘部分，显示部分通常采用液晶显示屏，为了满足视觉效果，也便于适用各种学习和工作需求，一般液晶屏幕的尺寸都在13英寸左右。为了实现便携，现有笔记本电脑已经向超薄化发展，但受到刚性液晶屏幕对笔记本电脑尺寸的限制，仍然无法摆脱方块状的外形，占用面积仍然很大，需要用电脑包携带，无法做到足够小巧，直接随身携带，仍然满足不了人们便携的要求。
中国专利（申请号：2016101414200）公开了一种笔记本电脑，其特征是：包括机体设投影仪及投影幕，不设显示屏，投影仪与机体电连接将影像投在随机的投影幕上取代显示屏，键盘及鼠标与机体无线连接可脱离使用。投影仪内设随机投影幕成笔记本电脑。作外投用途时，可取出键盘及鼠标随身使用，投影幕向下盖合，调节镜头方向及对焦如公知投影仪，一机多用无需易碎的平板显示屏。尽管采用了投影方式代替了液晶显示屏，但是，其投影幕不能折叠，机体和键盘均为一体结构，因此，不具备便携性。
中国专利（申请号：2011100781924）还公开了一种卷轴屏幕电脑，其特征是显示输出部分由在电脑机体上的投影模块和卷轴幕模块组合而成，卷轴幕模块包括幕布和幕布收展机构，幕布收展机构与电脑机体的外壳连接固定；幕布收展机构是以带弹性元件的主动刚性卷轴和被动刚性卷轴为核心、以刚性杆和铰链为支撑所组成的机构，在刚性杆上有定位构造，幕布两对边分别固定连接在两根刚性卷轴上。其幕布可以实现展开和收缩，提高了便携性，但是，其实施例仍然是刚性键盘，便携性受到限制。尽管该专利申请也提出可以采用折叠键盘，但是如何设置折叠键盘，如何与投影模块连接，如何收纳折叠键盘，使便携性的进一步提高，都没有进一步说明。若用柔性卷曲键盘或投影键盘代替刚性键盘，则改变了人们熟悉的操作键盘方式，影响手感和打字效率。

实施例2与实施例1主要结构基本相同，故具体结构不再赘述，不同之处在于，伸缩式投影幕布4上的伸缩架为两个X形伸缩架4.5, X形伸缩架4.5一端插入固定支撑板4.4一侧面上设置的长槽内，X形伸缩架4.5另一端插入转轴安装外壳4.1上设置的滑槽内。如图11所示，将转轴4.10竖直设置在转轴安装外壳4.1内且转动连接，转轴4.10为弹性回转轴，长方形幕布4.2的左右两端缠绕在弹性回转轴4.10上，弹性回转轴4.10依靠回转弹力自动卷绕长方形幕布4.2。通过两个X形伸缩架4.5展开或收缩实现长方形幕布4.2的展开或收缩。
参见图4-图7，本发明一体式便携投影电脑实施例1和实施例2折叠收缩过程各步骤状态，伸缩式投影幕布4折叠后覆盖在电脑主机3、电脑键盘1及投影模块5的上方时，最后，整机呈长方体形状。优选的，整机尺寸大约是宽度10厘米，长度18厘米，厚度4厘米。因为，体积和尺寸很小，不用电脑包就可以随时携带。
参见图8-图11，本发明一体式便携投影电脑实施例3，包括电脑主机3、电脑键盘1、投影模块5及伸缩式投影幕布4。电脑键盘1为折叠键盘，投影模块5与电脑主机3通过两侧的两块连接板2固定连接为一体，由投影模块5、电脑主机3及两块连接板2围合成的容纳空间用于折叠键盘1折叠后存放。将伸缩式投影幕布4设置在电脑主机3（或投影模块5）上。上述折叠键盘1为3节刚性键盘通过转轴铰接为一体，折叠键盘1用两根连接杆6与投影模块5铰接，折叠状态下的折叠键盘1的可以放置在上述的容纳空间内。上述折叠键盘1为3节刚性键盘通过转轴铰接为一体，折叠键盘1用两根连接杆6与投影模块5铰接，折叠状态下的折叠键盘1的可以放置在上述的容纳空间内。
实施例3与实施例1主要结构基本相同，故具体结构不再赘述，不同之处在于，伸缩式投影幕布4上的伸缩架为菱形伸缩架4.6,菱形伸缩架4.6对称设置在所述固定支撑板4.4上，菱形伸缩架4.6由交叉的连杆和连杆交叉部位的铰接轴铰接构成伸缩机构，菱形伸缩架4.6中间有两个上下设置的铰接轴。在固定支撑板4.4内侧面上竖向设置可旋转的左右旋丝杠4.7，在左右旋丝杠4,7上半部的左旋段套有上丝母4.8，在左右旋丝杠4.7下半部的右旋段上套有下丝母4.9，上丝母4.8和下丝母4.9分别与菱形伸缩架4.6中间的两个铰接轴连接。如图8、、图9、图11所示，在菱形伸缩架4.6的两个伸缩自由端上设置转轴安装外壳4.1，将转轴4.10竖直设置在转轴安装外壳4.1内且转动连接，转轴4.10为弹性回转轴，卷绕长方形幕布4.2的两端缠绕在弹性回转轴4.10上，弹性回转轴4.10依靠回转弹力自动卷绕长方形幕布4.2。
有一微型电机8通过柔性传动轴7与左右旋丝杠下端4.7连接，通过微型电机8正转或反转带动左右旋丝杠4.7正转或反转从而使菱形伸缩架4.6的两个伸缩自由端同步伸展或收缩，展开或卷起长方形幕布4.2。
本发明一体式便携投影电脑实施例3的折叠过程与实施例1-2基本相同。不同点是：实施例1-2为手动伸展或收缩伸缩式投影幕布4，而实施例3是可以通过微型电机8的正转或反转带动左右旋丝杠4.7正转或反转从而使菱形伸缩架4.6的两个伸缩自由端同步伸缩，展开或卷起所述长方形幕布4.2。
本发明一体式便携投影电脑实施例1-3中的长方形幕布4.2展开后可投影部分的对角线尺寸为14英寸左右，与笔记本电脑的液晶屏基本一致，可以满足使用需求。
当然，上述说明并非是对本发明的限制，本发明也并不限于上述举例，本技术领域的普通技术人员，在本发明的实质范围内所作出的变化、改型、添加或替换，也属于本发明的保护范围。
