图1-12示出根据本发明的一实施例的多功能转换装置的结构。如图1-图12所示，该装置包括上盖板100、下底板200和滑块300，上盖板100与下底板200上下连接而形成一壳状件。该壳状件内放置有电路板400。上盖板的前侧壁上开有第一通孔102和第二通孔103。
上盖板的上壁靠近该侧面处开有滑槽101。滑块300大部分位于该滑槽101 内。优选地，滑块300的厚度大于滑槽101宽度，避免滑块从滑槽被拔出。通过移动滑块可实现对第一通孔102或第二通孔103遮挡。
如图3所示，上盖板100的另一侧面上开有凹槽104。下底板200上设有与凹槽104相匹配的凸起201。上盖板100与下底板200通过凹槽104和凸起201的相配合来对齐并通过螺钉连接在一起。如图5所示，滑块300包括滑动部301和挡块302。滑动部和挡块上下连接或者形成为一体。滑动部至少部分从滑槽101露出，用于实现滑块的滑动。挡块302可完全位于该滑槽101内，用于实现对第一通孔或第二通孔遮挡。一实施例中，挡块302的长度大于第一通孔102的长度且大于第二通孔103的长度。挡块302的高度大于第一通孔宽度且大于第二通孔宽度。挡块302的长度大于第一通孔与第二通孔间距。
如图6所示，一实施例中，下底板200上设有限位块202。该限位块202位置与上盖板100的滑槽位置相对应。滑块300的挡块位于限位块202与上盖板100的一侧面之间。该限位块202两端设有第一限位部203和第二限位部204，用于对滑块的左右滑动实现限位功能。
如图7所示，一实施例中，下底板上固定放置有电路板400，该电路板400一端上设有第一接口401和第二接口402，其尺寸分别与第一通孔和第二通孔相匹配，其位置分别与第一通孔、第二通孔相对应。一实施例中，第一接口为USB电源口，第二接口为DC电源口。电路板另一端为输出端403。该输出端可为电源输出端。电路板400的输出端403中间部分与上盖板的凹槽相匹配。当上盖板与下底板连接时，电路板的输出端中间部分卡扣在上盖板的凹槽内。电路板的输出端的头部从上盖板的凹槽露出，用于接入外部电线，例如连接带有3.5mm插头的外部电线。
图8和图9示出上述实施例的一变型例的结构图。如图8-9所示，下底板200上设有导向槽205。导向槽下方开有第一定位球槽206和第二定位球槽207。第一定位球槽206和第二定位球槽207间距大于第一通孔长度且大于第二通孔长度。另一实施例中，第一定位球槽和第二定位球槽间距等于第一通孔和第二通孔间距。如图9所示，滑块的挡块下方开有盲孔303。盲孔303内设有弹簧304和滚珠305。弹簧304一端抵接于盲孔303的上壁，另一端与滚珠305对顶。滚珠305与盲孔303间隙配合。一实施例中，盲孔303位于挡块下方中心。滚珠尺寸与第一定位球槽和第二定位球槽均匹配。
图10和图11示出上述实施例的又一变型例的结构图。如图10所示，下底板200上设有导向槽208。导向槽208下方开有第三定位球槽209、第四定位球槽210、第五定位球槽211和第六定位球槽212。一实施例中，第三定位球槽209与第四定位球槽210间距和第五定位球槽211与第六定位球槽212间距相同。相应地，如图11所示，一实施例中，滑块的挡块下方开有第一盲孔309和第二盲孔306，第一盲孔内设有第一弹簧310和第一滚珠311，其中，第一弹簧一端抵接于第一盲孔的上壁，另一端与第一滚珠对顶。第一滚珠与第一盲孔间隙配合。第二盲孔内设有第二弹簧307和第二滚珠308，其中，第二弹簧一端抵接于第二盲孔的上壁，另一端与第二滚珠对顶。第二滚珠与第二盲孔间隙配合。一实施例中，第一盲孔与第二盲孔间距和第三定位球槽与第四定位球槽间距相同，且第一盲孔与第二盲孔间距和第五定位球槽与第六定位球槽间距相同。
滑块300的操作过程如下：手推滑块的滑动部左(右)滑，当挡块下方的滚珠滚至第二定位球槽(第一定位球槽)时，弹簧的推力将滚珠顶至第二定位球槽(第一定位球槽)内，滑块无法继续滑动，实现定位作用。此时，滑块的挡块完全挡住第一通孔(第二通孔)，第二通孔(第一通孔)完全露出。进一步，用户将与第二通孔(第一通孔)相匹配的接口线通过第二通孔(第一通孔)穿入，与电路板上的第二接口(第一接口)连接以为电路板提供电源。电路板的输出端的头部可接入外部电源线并连至外部设备(如Alexa)进行供电。
在一实施例中，电路板的输出端的头部接入的外部电源线设有3.5mm插头。该3.5mm插头可适应连接支持该插头的不同类型的语音助手(如Alexa、Google Home)。在一实施例中，电路板上设有无线信号收发模块，用于接收和发射无线信号，如WiFi、Zigbee或蓝牙等无线信号。
图12示出另一种滑块固定方式。如图12所示，滑槽设有第一卡扣部105和第二卡扣部106。滑块的挡块上设有分别与第一卡扣部105和第二卡扣部106相匹配的第三卡扣部312和第四卡扣部313。当手推滑块的滑动部左(右)滑，滑块的挡块上的第三卡扣部(第四卡扣部)与滑槽的第一卡扣部(第二卡扣部)相卡扣时，滑块难以继续滑动，实现定位作用。此时，滑块的挡块完全挡住第一通孔(第二通孔)，第二通孔(第一通孔)完全露出。
图13至图17示出本发明的另一实施例的多功能转换装置。如图13-图17所示，该装置包括上盖板500、下底板600、滑块700以及电路板。上盖板500 与下底板600相互连接而形成一壳状件。上盖板500的一侧面上开有滑槽501。滑槽上开有第一通孔502和第二通孔503。滑块700安装在滑槽501内，通过在滑槽内滑动以实现对第一通孔或第二通孔遮挡。优选地，滑块700的长度大于第一通孔502的长度且大于第二通孔503的长度。滑块700的高度与滑槽的高度相同。
如图15所示，滑块700包括滑动部702和挡块701。滑动部702与挡块701为前后连接。挡块的上边设有第一卡紧部703、第二卡紧部704，挡块的下边设有第三卡紧部705、第四卡紧部706。一实施例中，滑动部上设有多根条状部707，便于增加接触摩擦力，提高滑动速度。
如图16所示，滑槽的上边开有导向槽504，导向槽上设有第一固定部505、第二固定部506，第一固定部和第二固定部分别与第一卡紧部和第二卡紧部相匹配。如图17所示，下底板上设有导向槽601，下底板上的导向槽与滑槽的导向槽位置相对应，下底板上的导向槽设有第三固定部603和第四固定部602。第三固定部和第四固定部分别与第三卡紧部和第四卡紧部相匹配。
操作时，手推滑块的滑动部左(右)滑，当挡块的第一卡紧部(第二卡紧部)与滑槽的第一固定部(第二固定部)卡紧固定、第三卡紧部(第四卡紧部)与下底板上导向槽的第三固定部(第四固定部)卡紧固定，滑动无法继续滑动，实现定位作用。此时，挡块完全挡住第二通孔(第一通孔)，第一通孔(第二通孔)完全露出。
本方案实现滑块定位的另一方式与上述方案类似，下底板上的导向槽下方开有一定间距的两个定位球槽。挡块下方开有盲孔。盲孔内设有弹簧和滚珠。弹簧一端抵接于盲孔的上壁，另一端与滚珠对顶。滚珠与盲孔间隙配合。一实施例中，盲孔位于挡块下方中心，滚珠尺寸与两个定位球槽均匹配。操作时，手推滑块的滑动部左(右)滑，当挡块下方的滚珠滚至一定位球槽(另一定位球槽)时，弹簧的推力将滚珠顶至该定位球槽(另一定位球槽)内，滑块无法继续滑动，实现定位作用。此时，挡块完全挡住第二通孔(第一通孔)，第一通孔(第二通孔)完全露出。如图16-图17所示，一实施例中，上盖板另一侧面上开有凹槽507，下底板上相对于下底板导向槽另一端上设有与上盖板凹槽相匹配的凸起604，上盖板与下底板通过凹槽与凸起的配合对齐。
与上述方案类似，本方案一实施例中，下底板上固定放置有电路板，该电 路板一端上设有两个接口，尺寸分别与第一通孔、第二通孔相匹配，位置分别与第一通孔、第二通孔相对应。一实施例中，第一接口为USB电源口，第二接口为DC电源口。电路板的输出端中间部分与上盖板的凹槽相匹配，当上盖板与下底板连接时，电路板的输出端中间部分卡扣在上盖板的凹槽内，电路板的输出端的头部从上盖板的凹槽露出，用于接入外部电源线。
当挡块完全挡住第二通孔(第一通孔)，第一通孔(第二通孔)完全露出，用户将与第一通孔(第二通孔)相匹配的电源线通过第一通孔(第二通孔)穿入，与电路板上对应的第一接口(第二接口)连接。将电路板的输出端的头部接入外部输出电源线并连至外部设备(如Alexa)以对外部设备进行供电。类似地，该外部输出电源线可设有3.5mm插头，可适应连接支持该插头的不同类型的语音助手(如Alexa、Google Home)。在一实施例中，电路板上设有无线信号收发模块，用于接收和发射无线信号，如WiFi、Zigbee或蓝牙信号。
图18至图20示出根据本发明的另一实施例的多功能转换装置。如图18-图20所示，该转换装置包括上盖板800和下底板900。上盖板与下底板上下连接而形成一壳状体。上盖板的一侧面上开有第一通孔801、第二通孔802。与上述方案类似，上盖板的另一侧面上开有凹槽，下底板上设有凸起，该凸起与凹槽位置相对，上盖板与下底板通过凸起与凹槽的配合连接。在一实施例中，凹槽位于上盖板的另一侧面中间处。在一实施例中，下底板的四个边角处设有第一螺丝孔，上盖板内部的四个边角处设有第二螺丝孔，第二螺丝孔与第一螺丝孔位置分别相对且尺寸分别相匹配，分别通过将螺丝从第一螺丝孔穿入并穿进第二螺丝孔从而将上盖板与下底板固定连接。
如图19-图20所示，下底板上放置有电路板1000，电路板的一端上设有第一接口1001、第二接口1002和元器件1009，且第一接口和第二接口分别与第一通孔和第二通孔位置相对且尺寸相匹配，电路板的另一端为输出端1003。电路板的输出端中间部分与上盖板的凹槽相匹配。当上盖板与下底板连接时，电路板的输出端中间部分卡扣在上盖板的凹槽内。电路板的输出端的头部从上盖板的凹槽露出，用于接入外部输出电源线并连至外部设备(如Alexa)以对其进行供电。在一实施例中，电路板的输出端的头部接入的外部输出电源线设有3.5mm插头，可适应连接支持该插头的不同类型的语音助手(如Alexa、Google Home)。在一实施例中，电路板上设有无线信号收发模块，用于接收和发射无 线信号，如WiFi、Zigbee或蓝牙信号。
在一实施例中，第一接口和第二接口分别为USB电源口和DC电源口。在一实施例中，下底板上设有两个第三螺丝孔，电路板上设有两个第四螺丝孔，第三螺丝孔与第四螺丝孔位置分别相对且尺寸分别相匹配，分别通过将螺丝从第三螺丝孔穿入并穿进第四螺丝孔从而将电路板与下底板固定连接。在一实施例中，上盖板的另一侧面上靠近凹槽处开有重置孔。如图20所示，第一接口设有第一正极端1004、第一负极端1005，第二接口设有第二正极端1006、第二负极端1007、第三负极端1008，其中，第一正极端电连接于第二正极端，第一负极端电连接于第二负极端。第二负极端内部与第三负极端内部之间电连接有连接开关，当第二接口没有外部接口线插入时，连接开关闭合，当第二接口有外部接口线插入时，连接开关断开。在一实施例中，第二接口为元器件DC-092。在一实施例中，第二正极端与第三负极端分别与所述电路板的电源正极端和电源负极端连接。
本方案的工作过程如下：当外部接口线仅通过第一通孔穿入，与电路板上对应的第一接口连接，第二负极端内部与第三负极端内部之间的连接开关闭合，第一接口与元器件之间电路导通。当外部接口线仅通过第二通孔穿入，与电路板上对应的第二接口连接，第二负极端内部与第三负极端内部之间的连接开关断开，第二接口与元器件之间电路导通。当两根外部接口线同时分别通过第一通孔和第二通孔穿入，并分别与电路板上对应的第一接口和第二接口连接，第二负极端内部与第三负极端内部之间的连接开关断开，第一接口与元器件之间电路断开，第二接口与元器件之间电路导通，从而避免在同一时间两路接口同时工作导致电路短路的问题。如图21所示，多功能转换装置第一通孔接入外部接口线(USB电源线)，另一头(电路板的输出端的头部)通过电源线连至外部设备2000(Alexa)以对其进行供电，在一实施例中，多功能转换装置为Hub，内部电路板上设有转换电路，用于将一类无线信号转换成其他类无线信号，例如将WiFi信号转换成Zigbee信号。
本申请的多功能转换装置能够同时适应两种以上电源输入，但在同一时刻，仅有一路电源输入工作，由此可以防止由于同时输入两种以上不同的电压或电流而导致该转换装置损坏。本申请的多功能转换装置能够为设备供电，也能够接收无线信号，并对该无线信号进行转换，并传输到相应的设备。
以上已详细描述了本发明的较佳实施例，但应理解到，若需要，能修改实施例的方面来采用各种专利、申请和出版物的方面、特征和构思来提供另外的实施例。
考虑到上文的详细描述，能对实施例做出这些和其它变化。一般而言，在权利要求中，所用的术语不应被认为限制在说明书和权利要求中公开的具体实施例，而是应被理解为包括所有可能的实施例连同这些权利要求所享有的全部等同范围。
