Abstract

一种带后备电源的床上桌，包括一个普通的床上桌，其特征是：该床上桌的桌板内安装有充电电池(1)、充电控制器(2)、5V降压电源(3)、19V降压电源(4)，桌板外侧壁面设有充电电源线插口(5)、USB电源输出口(6)和笔记本电源输出口(7)，经过导线连接后形成回路。本实用新型实用性强，自带后备电源，可随时供低压台灯或笔记本取电，避免了扯拉市电到床上的不安全问题。

Description

带后备电源的床上桌
技术领域
本实用新型涉及床上桌，具体说是一种带后备电源的床上桌。
背景技术
床上桌也叫懒人桌，小巧且折叠可收，不占空间，用时打开放在床上，人就可以舒适地卧靠在床上，在桌上吃东西、写作业和打电脑了。此桌灵巧方便，深受人们喜爱。然而，此桌有个弊端，象做作业时，桌面区的光线不足，如果将台灯牵到桌面，其连带的220V电源线就成了一个安全隐患，特别是床上本来就不稳定，再加上人有时需要翻身移动，很有可能就扯拉到电源线，特别是对小朋友来说就更不安全；同样，在桌上打电脑时，笔记本没电了，把外接电源扯到床上也不安全。为此，我们很需要一种自带后备电源的的床上桌。
发明内容
本实用新型的目的是提供一种安全方便的带后备电源的床上桌。
所述带后备电源的床上桌，其特征是：该床上桌的桌板内安装有充电电池、充电控制器、5V降压电源、19V降压电源，桌板外侧壁面设有充电电源线插口、USB电源输出口和笔记本电源输出口，其中充电电源线插口连接到充电控制器，充电控制器输出端连接到充电电池的两极，充电电池并联连接到5V降压电源和19V降压电源，5V降压电源和19V降压电源的输出端分别连接到USB电源输出口和笔记本电源输出口。
本实用新型实用性强，自带后备电源，可随时供低压台灯或笔记本取电，避免了扯拉市电到床上的不安全问题，为人们生活更添方便和乐趣。
附图说明
图1是本实用新型结构示意图，
图2是本实用新型电气原理框图。
图中：1-充电电池，2-充电控制器，3-5V降压电源，4-19V降压电源，5-充电电源线插口，6-USB电源输出口，7-笔记本电源输出口。
具体实施方式
下面结合附图对本实用新型进一步说明：如图1、2中所示带后备电源的床上桌，在普通床上桌的桌板内安装有充电电池1、充电控制器2、5V降压电源3、19V降压电源4，桌板外侧壁面设有充电电源线插口5、USB电源输出口6和笔记本电源输出口7，其中充电电源线插口5与充电控制器2的输入端通过导线电连接，充电电池1的两极与充电控制器2的输出端电连接，5V降压电源3和19V降压电源4的输入端并联后接入充电电池1的两极、其输出端分别通过导线电连接到USB电源输出口6和笔记本电源输出口7。
充电电池1可以是做成安装可卸式的，也可以做成固定式的。
使用前，需要先将充电电池1充好电。将床上桌放在靠近插座的地方，将普通通用的电源延长线的尾插插入充电电源线插口5，在另一头将电源线插头插入市电插座，充电控制器2通电后开始给充电电池1充电，经过一段时间后，电充好后，拨下电源延长线和市电插座上的插头。
将桌打开后，放在床上。如果桌面光线不好时，可将USB台灯上的USB插头插入USB电源输出口6，充足电后的充电电池1就会通过5V降压电源3降压后经由USB电源输出口6给台灯供电。
同样，如果用笔记本没电时，可通过通用的连接线，将笔记本的电源入口连接到笔记本电源输出口7上，充电电池1就会通过19V降压电源4降压后经由笔记本电源输出口7给笔记本供电。
