Description

自动卡位限位读写板及读写平台 技术领域
本发明涉及一种读写板，尤其涉及自动卡位限位读写板及读写平台。
背景技术
传统的读写平台一般为普通的桌面、茶儿等形式，其本身就不太适合用户在上面作长时间地书写、阅读、绘画、打字等。但人类把桌面造成斜面的话，又完全不方便摆放东西。因此绝大部分人，一直在无可奈何下，被迫伏案进行上述活动。
近年市场上出现的一些可调角度读写板、读写架，结构简陋落后，用户需要手动在面板背后锁定或固定支撑物，使用极为不便。而非外置式的整张可调角度学习桌，笨重，占地面积大，摆放、使用又不灵活，价格亦昂贵很多，而且不便于与中小学生的课桌结合使用，使用范围窄。
发明内容
针对上述技术问题，本发明公开了自动卡位限位读写板及读写平台，实现自动卡位限位，同时又非常纤簿，可以灵活的与各种平台、课桌等结合使用。
对此，本发明的技术方案为：

采用此技术方案，抬起面板时，伸缩支撑板伸出，并通过限位构件限位固定，实现自动卡位功能，用户不需要在面板后面手动卡定或锁紧任何支撑物。闭合面板时，只需把面板稍稍向上提，再下放就能解除卡位，顺势就可以一直放至最低，变回水平状态。使用方便，结构简单，可以做的很纤薄，灵活方便。
作为本发明的进一步改进，所述伸缩支撑板包括支撑板和支撑板基座；所述支撑板与支撑板基座活动连接；所述支撑板与面板的背部或侧边转动连接，所述支撑板基座与支架转动连接；支撑板伸出后，所述支撑板基座通过限位构件与支撑板连接。进一步，所述支撑板与支撑板基座滑动连接。采用此技术方案，抬起面板，带动支撑板相对于支撑板基座滑动，伸出于支撑板基座，限位构件进行限位，支撑板与支撑板基座之间停止滑动，从而支撑板起到支撑面板的作用，使面板与支架呈一定角度，这样 可以方便使用者使用。
作为本发明的进一步改进，所述支撑板基座设有滑道，所述支撑板与滑道配合，所述支撑板通过滑道与支撑板基座滑动连接；

作为本发明的进一步改进，所述卡接件为卡扣，所述卡扣与支撑板基座转动连接；所述配合件为卡槽。
作为本发明的进一步改进，所述卡扣的中部通过转轴与支撑板基座转动连接，所述卡扣的两端设有缺口；所述卡槽的一侧设有凸出的卡位，所述卡槽的下部设有与卡扣的缺口相对的撞击角。进一步的，所述缺口为V型缺口。所述卡位位于卡扣行程上、并在卡扣旋转的范围内。采用此技术方案，当抬起面板时，支撑板伸出支撑板基座后，当支撑板基座的卡扣与支撑板的卡槽配合，就将支撑板卡住，面板此时也处于开启状态，与支架呈一定的角度固定。再向上抬起面板，使支撑板基座的卡扣与支撑板的卡槽脱离，然后放下面板，此时卡扣与卡槽脱开，持续放下面板，支撑板收拢到支撑板基座中，从而使面板与支架合拢，实现了收缩。
进一步的，所述卡位的顶部距离转轴的距离小于卡扣任一端的V型的缺口顶端距离转轴的距离。
作为本发明的进一步改进，所述支撑板伸出使卡扣的缺口接触撞击角时，所述撞击角的顶点与卡扣的缺口的侧边接触。
所述撞击角的顶点位于以卡扣的转轴为圆心、卡扣的缺口的顶点为半径的圆外。
作为本发明的进一步改进，所述支撑板设有限位槽，所述卡扣位于限位槽内，所述限位槽的宽度大于卡扣的宽度，所述限位槽与卡槽连通。
作为本发明的进一步改进，所述卡扣为至少两个，分别位于支撑板基座的两侧，所述支撑板的两侧均设有卡槽，所述支撑板的侧边与支撑板基座的相对的一侧之间形成限位槽，所述卡槽与限位槽连通。

具体实施方式
下面结合附图，对本发明的较优的实施例作进一步的详细说明。
实施例1
如图1～图7所示，一种自动卡位限位读写板，其包括面板1、支架2和包含限位构件的伸缩支撑板3，所述面板1与支架2的一侧通过转轴转动连接；所述伸缩支撑板3包括支撑板31和支撑板基座32。所述支撑板基座32与支架2的另一侧通过转轴转动连接，所述支撑板31与面板1的背部通过转轴转动连接。所述支撑板基座32内设有滑道33，所述支撑板31伸入到滑道33中，所述支撑板31通过滑道33与支撑板基座32滑动连接。支撑板31伸出后，所述支撑板基座32通过限位构件与支撑板31连接。
进一步的，所述限位构件包括卡接件和配合件，所述卡接件设在支撑板基座32的滑道33内，所述配合件设在支撑板31的下部。本实施例中，所述卡接件为卡扣34，所述卡扣34与支撑板基座32转动连接。所述配合件为卡槽35。所述支撑板31设有限位槽36，所述卡扣34位于限位槽36内，所述限位槽36的宽度大于卡扣34的宽度，所述限位槽36与卡槽35连通，所述卡槽35的宽度大于限位槽36的宽度。即卡扣34在限位槽36内相对移动到卡槽35。所述卡扣34的中部通过转轴与支撑板基座32转动连接，所述卡扣34的两端对称的设有V型的缺口37。所述卡槽35的一侧设有凸出的卡位38，所述卡槽35的下部设有与卡扣34的缺口37相对的凸出的撞击角39，起到撞击卡扣34使其转动的作用。所述卡位38位于卡扣34的行程上、并在卡扣34旋转的范围内，即所述卡位38的顶部距离转轴的距离小于卡扣34任一端的V型的缺口37顶端距离转轴的距离。所述撞击角39的顶点位于以卡扣34的转轴为圆心、卡扣34的缺口37的顶点为半径的圆外。所述支撑板31伸出使卡扣34的缺口37接触撞击角39时，所述撞击角39的顶点与卡扣34的缺口37的侧边接触。正常情况下，卡扣34的长度方向与限位槽36延伸方向相同，两侧的缺口37位于长度方向上，缺口37位于竖直方向，这样，当卡扣34的缺口37撞击到撞击角39，撞击角39使卡扣34转动，使 得卡扣34位于卡位38的下方，当卡扣34接触到卡位38时，被卡位38卡住，起到限位的作用。
进一步的，所述面板1内设有可移动的拨钮4，当面板1与支架2收拢时，移动拨钮4使其与支架2接触，当需要打开面板1时，先拨动拨钮4，使其不与支架2接触，面板1和支架2可以发生转动，这样伸缩支撑板3就可以打开。这样，可以在面板1收拢时，固定面板1和支架2的相对位置，使得面板1与支架2不发生转动，从而固定伸缩支撑板3，便于携带。进一步的，所述面板1背部设有容纳支架2的凹槽，收拢时，支架2嵌入到面板1的背部。进一步的，所述面板1的下部设有可收拢的活动托板5。采用此技术方案，在面板1抬起时，打开此活动小托班可以方便放文具。
采用此技术方案，抬起面板1时，面板1相对于支架2转动，从而使得与面板1连接的支撑板31伸出于支撑板基座32，支撑板基座32也相对支架2转动；卡扣34与限位槽36相对移动，当卡扣34到达卡槽35时，卡扣34撞击到撞击角39，使得卡扣34转动，支撑板31相对支撑板基座32往回移动，使转动后的卡扣34的缺口37卡到卡位38中，从而实现限位。当收拢，将面板1再往上抬起一点，使卡扣34向着与原先相反的方向转动，回到或接近初始的状态，即卡扣34的长度方向与限位槽36延伸方向相同或接近相同，这样就可以顺利使得支撑板31缩回到支撑板基座32中，从而使得面板1收拢。
整个过程中，支撑板31伸出，并通过限位构件限位固定，实现自动卡位功能，用户不需要在面板1后面手动卡定或锁紧任何支撑物。闭合面板1时，只需把面板1稍稍向上提，再下放就能解除卡位38，顺势就可以一直放至最低，变回水平状态。使用方便，结构简单，可以做的很纤薄，灵活方便。
实施例2
如图8～图10所示，一种书桌，其包括支撑架6和桌面7，所述桌面7中设有实施例1所述的自动卡位限位读写板，所述支架2与桌面7连接。自动卡位限位读写板的面板1收拢时后，面板1与桌面7在一个平面内；抬起面板1，面板1与桌面7呈钝角，方便读写。本发明的自动卡位限位读写板，用途可做成独立的读写板、书桌面板、笔电底座。
实施例3
如图11～图12所示，一种办公桌，其包括办公桌台面8，所述办公桌台面8设有 实施例1所述的自动卡位限位读写板，所述自动卡位限位读写板的支架2与办公桌面8连接。自动卡位限位读写板的面板1收拢时后，面板1与办公桌面8在一个平面内；抬起面板1，面板1与办公桌面8呈钝角，方便读写。
实施例4
如图13～图14所示，一种电脑底座，所述电脑底座包含实施例1所述的自动卡位限位读写板结构，其包括面板1、支架2、包含限位构件的伸缩支撑板3和可移动的拨钮4，所述面板1内设有当面板1与支架2收拢时，移动拨钮4使其与支架2接触，当需要打开面板1时，先拨动拨钮4，使其不与支架2接触，面板1和支架2可以发生转动，这样伸缩支撑板3就可以打开。所述面板1上还设有散热机构9，所述散热机构9包括位于面板1上的散热槽和位于散热槽内的散热风扇。进一步的，本实施例中的支架2为支撑杆。
实施例5
在实施例3的基础上，如图15～图17所示，一种桌面板，其包括桌面板台面10，所述桌面板台面10设有如实施例1所述的自动卡位限位读写板，所述自动卡位限位读写板的支架2与桌面板台面10通过螺钉连接。自动卡位限位读写板的面板1收拢时后，面板1与桌面板台面10在一个平面内；抬起面板1，面板1与包括桌面板台面10呈钝角，方便读写。本实施例中，所述支架2与面板1的两侧连接。为了方便安装，所述支架2的两侧为L型结构。
实施例6
在实施例1的基础上，如图18～图19所示，一种自动卡位限位读写板，本实施例中，所述卡扣34为两个，分别位于支撑板基座32的两侧，所述支撑板31的两侧均设有卡槽35，所述支撑板31的侧边与支撑板基座32的相对的一侧之间形成限位槽36，所述卡槽35与限位槽36连通。所述卡扣34的两端对称的设有V型的缺口37，所述卡槽35的上部设有凸出的卡位38，所述卡槽35的下部设有与卡扣34的缺口37相对的凸出的撞击角39，起到撞击卡扣34使其转动的作用。工作原理与实施例1的相同。
实施例7
在实施例1的基础上，如图20-21所示，一种自动卡位限位读写板，本实施例中，所述限位构件包括卡接件和配合件，所述卡接件为卡扣41，所述卡扣41设在支撑板基座32的滑道内，并与支撑板31的下部转动连接，所述配合件为位于支撑板基座32上 与卡扣41位置对应的卡条形的卡槽42，所述卡槽42沿纵向设有若干卡接槽43，所述支撑板31设有用于安装卡扣41的安装槽，所述卡扣41与安装槽内与卡槽42相对的一侧的侧壁之间设有弹簧44。本实施例中，所述卡扣41为两个，分别位于支撑板31的两侧，所述卡槽42也为两个，位于支撑板基座32的两侧。
采用此技术方案，抬起面板1时，面板1相对于支架2转动，从而使得与面板1连接的支撑板31伸出于支撑板基座32，支撑板基座32也相对支架2转动；卡扣41与卡槽42相对移动，当卡扣41到达卡槽42的每个卡接槽43位置时，卡扣41在弹簧44的作用下与卡接槽43卡接，实现限位。反之同理，当收拢时，将面板1再往上抬起一点，使卡扣41向着与原先相反的方向转动，回到或接近初始的状态，这样就可以顺利使得支撑板31缩回到支撑板基座32中，从而使得面板1收拢。
实施例8
在实施例7的基础上，如图22-23所示，一种自动卡位限位读写板，本实施例中，所述卡扣41位于支撑板31的两侧边的下部，所述支撑板基座32的滑道33内、在位于支撑板基座32的外侧与支撑板31的侧边之间设有卡槽42，所述卡槽42为卡条形，且位置与卡扣41位置对应，所述卡槽42沿纵向设有若干卡接槽43。本实施例中的卡扣41的下部包括第一卡脚46和第二卡脚47，所述第一卡脚46位于第二卡脚47的外侧，且第一卡脚46的底部超出第二卡脚47。
所述支撑板31设有用于安装卡扣41的安装槽48，所述卡扣41与安装槽内与卡槽42相对的一侧的侧壁之间通过扭簧46连接，所述安装槽48的底部设有限位凸起49，所述限位凸起49位于第一卡脚46的内侧，用于限制第一卡脚46进入安装槽内。所述第二卡脚47的底部不超过限位凸起49的顶部。
采用此技术方案，抬起面板1时，面板1相对于支架2转动，从而使得与面板1连接的支撑板31伸出于支撑板基座32，支撑板基座32也相对支架2转动；卡扣41与卡槽42相对移动，当卡扣41到达卡槽42的每个卡接槽43位置时，卡扣41在扭簧45的作用下与卡接槽43卡接，实现限位。反之同理，当收拢时，将面板1再往上抬起一点，使卡扣41向着与原先相反的方向转动，回到或接近初始的状态，这样就可以顺利使得支撑板31缩回到支撑板基座32中，从而使得面板1收拢。
