Description

一种多功能充电插座 技术领域
本实用新型 涉及插座领域，尤其涉及一种多功能充电插座。
背景技术
随着手机、平板电脑等电子设备使用的普及，人们对这些电子产品的充电电源使用越来越频繁。目前，人们日常普遍通过将连接USB数据线的充电插头插在插座上对电子产品进行充电。这种方式的缺点主要在于因为充电插头体积较大，同一插座上只能同时对一个设备进行充电。为了解决这一问题，现有技术做了一定改进。申请公布号为CN 102544863 A，申请公布日为2012.07.04的中国发明专利USB充电墙壁插座在普通墙壁插座上设置了USB接口，使得多个电子产品可以一起进行充电。但这种改进也有使用不方便的缺点，需拆除原来电源插座，更换为USB充电墙壁插座，且需专业人员安装。
发明内容
为了解决上述现有技术中存在的问题，本实用新型提供一种多功能充电插座。
本实用新型提出的多功能充电插座包括：壳体上设置的用于套装通用插座的插孔，壳体背面左右两侧设置的与插座电连接的一对金属弹片以及用于将外壳固定在墙体插座上的卡扣，所述壳体上还设有至少一个USB充电接口和交直流电转换模块。
所述壳体通过螺钉与墙体插座连接。所述USB接口包括Android系统手机专用USB接口和iOS系统手机专用USB接口中的一种，或同时包括两种接口。所述壳体上还设有用于放置手机的卡板。墙体插座包括两扁头插座、两扁头一圆头插座、三圆头插座、两圆头插座和三扁头插座。交直流转换模块设有可控制USB接口输出电压及电流大小的充电电路。
壳体正面设有套装通用墙体插座的插孔，把充电插座插入墙体插座后，壳体背面左右两侧设置的金属弹片与墙体插座电接触，墙体插座上的交流电通过金属弹片给充电电路供电。壳体背面设置的卡扣用于将充电插座固定在墙体插座上。充电插座壳体正面设有用于与墙体插座固定的螺丝孔。安装时先把原墙体插座外壳拆下，再把设有USB充电接口的充电插座插入墙体插座，轻轻按压，背部卡扣就会扣在墙体插座上，再将螺丝插入螺丝孔扭紧就可以使用。安装简单，且无需专业人员安装。
本实用新型结构设计巧妙，使用十分方便，可适用多种墙体插座，为普通墙体插座增加USB充电接口，实现随时随地为手机、平板电脑等终端电子设备充电的目的。此外，针对市面上两大操作系统的电子产品，Android系统和iOS系统，由于其充电电流范围不同，本实用新型针对不同系统的电子设备设置了不同的USB接口，通过内部的充电电路控制不同的USB接口输出不同大小的电流值，从而使不同系统的电子设备均可在其最大充电电流范围内进行充电，提高了充电效率，可实现快速充电。

具体实施方式
下面结合附图和具体实施例对本实用新型进一步进行说明。
如图1所示，本实用新型实施例一VG-100型充电插座包括：壳体正面下部右侧设有一个用于手机充电的USB接口1，壳体正面设有用于与通用墙体插座进行套装的插孔2，壳体背面左右两侧各设有一个金属弹片3与通用墙体插座电连接导电，本实施例中，金属弹片采用T字款金属弹片，其具体结构如图5所示，壳体背面插孔2下方设有用于将插座外壳固定在通用墙体插座上的一对卡扣4，使用卡扣固定十分方便简单，仅需将插座外壳向墙体插座轻轻按压即可，壳体还设有用于与通用墙体插座固定的螺丝孔5，通过螺丝孔可以将充电插座牢固的固定在墙体插座上。
如图2所示，本实用新型实施例二VG-200型充电插座包括：壳体正面下方设有两个用于手机充电的USB接口1，壳体正面还设有用于与墙体插座进行套装固定的插孔2，壳体背面左右两侧各设有一个金属弹片3与墙体插座电连接导电，本实施例中，金属弹片采用加厚款金属弹片，其具体结构如图6所示，壳体背面设有用于将插座外壳固定在墙体插座上的一对卡扣4，壳体正面还设有用于与墙体插座固定的螺丝孔5。
如图3所示，本实用新型实施例三VG-300型充电插座包括右侧侧面设置的一个用于手机充电的USB接口1，壳体上部设有用于与通用墙体插座进行套装固定的插孔2，壳体背面左右两侧各设有一个金属弹片3与通用墙体插座电连接导电，本实施例中，金属弹片采用反方向款金属弹片，其具体结构如图7所示，壳体背面插孔2下方设有用于将插座外壳固定在通用墙体插座上的一对卡扣4，壳体正面还设有用于与通用墙体插座固定的螺丝孔5，此外，本实施例还设计了用于放置电子设备的卡板6，当USB充电接口充电插座安装在通用墙体插座上后，卡板6、USB充电接口充电插座与墙壁之间形成可放置电子设备的凹槽，电子设备充电时可放置在卡板形成的凹槽中。
如图4所示，本实用新型实施例四VG-500型充电插座包括壳体正面右侧设置的两个用于手机充电的USB接口1，壳体正面设有用于与通用墙体插座套装固定的插孔2，壳体背面左右两侧各设有一个金属弹片3与通用墙体插座电连接导电，本实施例中，金属弹片采用反方向T字款金属弹片，其具体结构如图8所示，壳体背面插孔2上方设有用于将插座外壳固定在通用墙体插座上的一对卡扣4，壳体正面还设有用于与通用墙体插座固定的螺丝孔5。此外，本实施例也设计了用于放置电子设备的卡板6，当USB充电接口充电插座安装在通用墙体插座上后，卡板6、USB充电接口充电插座与墙壁之间形成可放置电子设备的凹槽，电子设备充电时可放置在卡板形成的凹槽中。
本实用新型常用的金属弹片包括：T字型款、加厚款、反方向款和反方向T字型款，其具体结构分别如图5、图6、图7和图8所示。当USB接口充电插座与通用墙体插座固定后，金属弹片与原墙体插座内的导电铜片接触后使充电电路获得所需的交流电，而交直流电转换模块可将交流电转化为用于电子设备充电的直流电从而为USB接口供电。通用墙体插座包括多种常用的两扁头插座、两扁头一圆头插座、三圆头插座、两圆头插座和三扁头插座。
因上述实施例在安装方式和实现快速充电原理上完全相同，故统一进行说明。充电插座的壳体内部的交直流电转换模块设有一可控制USB接口输出电流大小的充电电路。充电电路可控制不同USB接口输出不同大小的电流。具体来说，USB接口共有两种，Android系统电子设备专用USB接口和iOS系统电子设备专用USB接口，实施例一VG-100型充电插座、实施例三VG-300型充电插座仅设有一个USB接口，因此只能为Android系统电子设备专用USB接口或iOS系统电子设备专用USB接口中的一种；而实施例二VG-200型充电插座、实施例四VG-500型充电插座设有两个USB接口，因此能够同时设置Android系统电子设备专用USB接口和iOS系统电子设备专用USB接口。
图9是单USB接口充电电路的电路图，图10是单USB接口充电电路实现快充作用原理的方框图。现结合图9对本实用新型的快充原理做进一步说明。对于单一USB接口的VG-100、VG-300型插座外壳，当AC INPUT电压输入整流电路1时，1将交流电转化成直流电，再经输入端的滤波电路2进行平滑的滤波后进入功率转换电路3，3的辅助绕组感应到的电压使芯片U1工作，然后能量通过输出端的整流电路4进行整流，输出端的滤波电路5将弱电进行平滑滤波，滤波后由5进行电压采样限定，将信号送到U1内部进行开关磁能控制，周而复始的进行无休止的循环直至达到所需要的稳定的直流弱电电压到USB充电接口。单USB充电接口可以对协议信号进行反馈实现快充，协议信号的工作原理为：当协议信号收到回馈的指令时由芯片U2进行分析，改变分压电路6中的分压电阻排列方式，基准电压送到U1内部改变工作方式，然后形成功率转换电3的往复循环工作，最终达到协议需求的平滑的DC弱电电压，从而实现快速充电。
图11是双USB接口充电电路的电路图，图12是双USB接口充电电路原理的方框图。现结合图11对双USB接口充电电路的原理做进一步说明。对于双USB接口的VG-200、VG-500型插座外壳，两接口USB1、USB2分别设为Android系统电子设备专用USB接口和iOS系统电子设备专用USB接口，当AC INPUT电压输入整流电路1时，1将交流电转化成直流电，输入端的滤波电路2进行平滑的滤波后进入功率转换电路3，3的辅助绕组感应到的电压使芯片U1工作，芯片U1进行磁能控制使得能量信号周而复始的循环工作。然后能量经过输出端的整流电路4进行转换将能量进行整流，然后通过输出端的滤波电路5将弱电进行平滑滤波，滤波后输出到USB1、USB2进行充电使用。
现对本实用新型的具体使用过程进行说明，当使用本实用新型时，首先关闭墙体插座电源，拆除原始墙体插座盖板，然后将本实用新型的设有USB充电接口的充电插座插入墙体插座后。金属弹片就会和壁装墙体插座交流电接电端连接在一起，为充电电路提供电源；本实用新型的卡扣会与墙体插座初步固定，并通过插座外壳上的螺丝与通用插座进一步牢固固定。安装简单方便，即不影响原墙体插座使用功能，又增加了给手机,ipad等终端电子产品充电的功能。
此外，本实用新型不限于在上述提到的侧面设有单一USB接口的VG-100、VG-300型充电插座和正面设有两接口的VG-200、VG-500型充电插座，若有需要，可合理增加USB接口数量、调整USB接口位置。以上四款是发明人在研发过程中充电效果较佳且造型美观的代表性产品，故作为实施例进行说明，但是以上的具体实施例仅用以举例说明本实用新型的构思，本领域的普通技术人员在本实用新型的构思下可以做出多种变形和变化，这些变形和变化均包括在本实用新型的保护范围之内。
