Description

插头结构及电子设备
本申请要求于2019年10月14日提交的，申请号为201910974381.6，名称为“插头结构及电子设备”的中国专利申请的优先权，该中国专利申请的全部内容通过引用结合在本文中。
技术领域
本发明涉及电器领域，特别涉及一种插头结构及电子设备。
背景技术
随着电子产品的日益增多，特别是便携式产品的出现更是极大便利了人们的生活。但随之大量电子产品都需要配备电池供携带时续航，而不可重复使用的电池无疑是种巨大的浪费，因此现有电子产品大多配备的是可充电电池，对应均需要配备充电器。
发明内容
本公开的目的在于提供一种体积较小，可以方便收纳携带的插头结构及电子设备。
根据本公开的第一方面，提供一种插头结构，包括插头本体及插头；
所述插头本体设有用于收容所述插头的收容槽；
所述插头包括一转轴及多个插脚；
所述转轴滑动设于所述收容槽内，可转动至至少一第一位置和一第二位置；
当所述转轴转动至所述第一位置，所述多个插脚收容于所述收容槽；
当所述转轴从所述第一位置朝向所述插头本体的顶端转动至所述第二位置，所述多个插脚从所述收容槽穿出所述插头本体。
根据本公开的第二方面，提供一种电子设备，包括电路模块及上述第一方面的插头结构，所述电路模块与所述插头结构的插脚电连接。
在上述插头结构中，插脚可以处于收折状态，以收容于收容槽内。当需要打开使用的时候，插脚可以沿滑槽滑动及转动，使插脚伸出以供使用。因此，上述插头结构在不使用的时候，插脚收回，可以减小插脚的占用空间，便于携带及收纳。
同时，在插脚滑动至工作状态的过程中，转轴从第一位置转动至第二位置，插脚朝向插头本体的顶端移动，从而减小插脚与插头本体的顶端端面之间距离。因此，当上述插头结构插接于插座上的时候，插头结构占用的空间较小，不会“霸占”到相邻位置处的插座空间，不会影响其他插头结构的插接使用。
因此，使用含有该插头结构的电子设备中，其中插头结构的占用空间较小，也便于电子设备的携带及使用，并且，可以避免电子设备插接在插座上，影响其他电子设备的插接使用。

以下结合本说明书的附图，对本发明的较佳实施方式予以进一步地详尽阐述。
目前，充电器的插头结构由于具有多个外伸的插脚，使充电器的插头结构往往占用较大的空间，不利于便携收纳。
本公开提出一种电子设备。电子设备包括电路模块及插头结构。电路模块与插头结构电连接。电路模块与插头结构可以为一体结构，插头结构内设有用于收容电路模块的收容仓。或者，电路模块与插头结构也可以为分体式结构，电路模块与插头结构之间可拆卸连接。
电子设备可以为充电器、移动电源或转接插头等。具体在本公开中，电子设备以充电器，电路模块为充电模块为例进行说明。
在一些实施方式中，请参阅图1及图2，充电器1包括充电模块10及插头结构20。插头结构20的插头本体21内设有收容仓30。收容仓30用于收容充电模块10，充电模块10与插头结构20的插头22电连接。插头结构20用于与外接电源连接，以为充电模块10提供电源。充电模块10与待充电装置电连接，以对待充电装置进行充电。
充电模块10包括主板11及设于主板11上的电子元器件(图未示)。充电模块10的一端与插头22电连接，另一端与待充电装置电连接，以对待充电装置进行充电。其 中，待充电装置可以为智能移动终端、移动电源、笔记本电脑、无人机、电子书、电子烟、智能穿戴设备、扫地机器人等电子设备。此处对充电器的应用充电对象不做限定。
在一些实施方式中，插头结构20为二极插。即，二极插具有两个插脚。可以理解，插头结构20还可以为二极带接地插。二极带接地插具有三个插脚。
在一些实施方式中，插头结构20包括插头本体21及插头22。插头本体21设有用于收容插头22的收容槽211。插头22靠近插头本体21的顶端210设置，收容槽211朝向插头本体21的顶端210延伸。第一位置与第二位置为收容槽211上两个不同位置。第一位置与第二位置距离插头本体21的顶端210的距离不同。第一位置可以位于收容槽211的一端，第二位置位于收容槽211的另一端。可以理解，第一位置与第二位置还可以位于收容槽211的中部区域。并且，第一位置及第二位置还可以为多个。只要在收容槽211的延伸方向上，第一位置与第二位置之间存在一定间距即可，此处对第一位置及第二位置的个数并不做限定。
在一些实施方式中，插头本体21可以为一矩形盒体。插头本体21的两个短边端分别为插头本体21的底端及顶端210。收容槽211的延伸方向与插头本体21的长边方向平行。
插头22包括一转轴221及多个插脚222。转轴221滑动设于收容槽211内，可转动至至少一第一位置和一第二位置。即，转轴221沿收容槽211在第一位置与第二位置之间，靠近或远离插头本体21的顶端210运动。
请参阅图3，当转轴221转动至第一位置，多个插脚222收容于收容槽211，转轴221与收容槽211的底部抵持，插头机构20的插头22处于收折状态。请参阅图4，当转轴221从第一位置朝向插头本体21的顶端210转动至第二位置，转轴221朝向插头本体21的顶端210运动，转轴221滑动至离插头本体的顶端210端面第一距离的位置，多个插脚222从收容槽211穿出，并垂直于插头本体21。因此该插头结构20可以实现与外接插座进行插接，插头结构20处于工作状态。
插头22可以处于收折状态，插头22可收折于收容槽211内。因此，上述插头结构20在不使用的时候，插头22可以收回，可以减小插头22的占用空间，便于携带及收纳。
并且，请参阅图5及图6，当插头结构20需要打开插头22使用的时候，插头22可以沿收容槽211朝向插头本体21的顶端210滑动至第二位置。多个插脚222从收容槽211穿出，并垂直于插头本体21，插头以实现与外接插座进行插接，插头结构20处于工作状态。由于，第二位置为转轴221滑动至离插头本体的顶端210端面第一距离A的位置处，则第二位置相对于第一位置更靠近插头本体21的顶端210端面。转轴221滑动至离距离所述插头本体顶端210端面第一距离A的位置，则使插脚222能够靠近插头本体21的顶端210端面，使插脚222与插头本体的顶端210端面之间的距离减小。
在传统的插头中，当插脚处于工作状态的时候，其插头本体的边缘的插脚之间的距离通常至少为15.8毫米，插头本体边缘与插脚之间的距离较大，占用较大空间。当将上述插头结构插接于插座上的时候，插头结构会占用较大的空间，插头本体的边沿占用的面积较大，导致插座本体会“霸占”到相邻位置的插座的插孔，影响相邻位置的插座的使用，发生“霸王插头”现象。
请参阅图4，在上述插头结构20中，当插头22处于工作状态。此时，处于第二位置的插头22相较于第一位置，较为靠近插头本体21的一端的顶端210端面，减小插脚222与插头本体21一端顶端210端面之间距离。因此，处于工作状态的插头结构20的插脚222距离插头本体21的顶端210端面的距离得到减小，因此可以减小上述插头结构20的边沿占用的空间。当插头结构20插接于插座上的时候，不会“霸占”到相邻位置处的插座空间，不会影响其他插头结构的插接使用。
在一些实施方式中，当插脚222位于第二位置的时候，转轴221距离收容槽211的底部的第一距离A为6.5mm。因此，在收容槽211的延伸方向上，插脚222与插头本体21的顶端端面之间的距离可以达到6.5毫米。由于插头结构20的顶端210端面与插脚222之间至少具有6.5毫米的距离，以避免手指触电接触到插片，满足插头结构20的安全规范标准。
并且，插头本体21的顶端210端面与插脚222之间的最小距离可以达到6.5毫米，使插头本体21的外侧边缘占据的空间最小，在保证上述插头结构安全使用的前提下，最大程度的避免了“霸王插头”现象的发生。
在一些实施方式中，请参阅图2，插头本体21包括上壳212及下壳213。上壳212与下壳213配合连接，且上壳212与下壳213共同围成收容槽211。上壳212与下壳213之间可以通过卡合、螺接或热熔等方式实现固定连接。在其他实施方式中，插头本体21不限于分为上、下两结构部分，还可以是其他结构组成形式，此处对插头本体21的结构组成并不做限定。
请同时参阅图7，并且，上壳212开设有上收容仓301。主板11固定于上收容仓301内。并且，上收容仓301的形状与主板11的形状相适配。主板11卡合固定于上壳212的上收容仓301内。
请参阅图8，上壳212开设有供插脚222转出收容槽211的过孔2121。过孔2121与收容槽211连通，插脚222从上壳212的一侧转出至插头本体21外侧。
请参阅图9，下壳213开设有下收容仓302。下收容仓302对应收容于设于主板11上的电子元器件。并且，下收容仓302的形状与上收容仓301的形状相适配。上壳212与下壳213可以为注塑成型的塑胶件。并且，上壳212与下壳213为一体结构。上壳212与下壳213可以保持较高的制作精度，也可以方便成型。
收容槽211包括一用于收容转轴221的第一收容槽2111，及分别用于收容两插脚222的第二收容槽2112及第三收容槽2113。两插脚222位于转轴221的两侧，则第二 收容槽2112及第三收容槽2113分别位于第一收容槽2111的两侧。转轴221沿第一收容槽2111移动，两插脚222分别沿第二收容槽2112及第三收容槽2113移动。
在一些实施方式中，第一收容槽2111为圆弧形，转轴221沿第一收容槽2111转动至第二位置。相应地，第二收容槽2112及第三收容槽2113也为圆弧形。当转轴221沿第一收容槽2111移动的时候，两插脚222也随之沿第二收容槽2112及第三收容槽2113移动。第二收容槽2112及第三收容槽2113的槽口宽度与插脚222的宽度相适配，以使插脚222能够稳定收容于第二收容槽2112及第三收容槽2113内。
在一些实施方式中，第一收容槽2111包括一圆弧槽214。圆弧槽214设于下壳213上。上壳212设有与圆弧槽214的形状相适配的凸台215。上壳212的凸台215的顶面与圆弧槽214的底面之间形成用于插头22滑动的通道。可以理解，该通道也可直接形成于上插头本体212或下壳213上。
转轴221沿圆弧槽214转动至第二位置。圆弧槽214的底面形状为圆弧形凹面。则凸台215具有圆弧形凸面。圆弧形凹面与圆弧形凸面相互适配形成一圆弧形通道。则转轴221沿该圆弧形通道滑动。
在一些实施方中，第一位置2141及第二位置2142分别对应于圆弧槽214的两端。转轴221沿圆弧槽214移动的时候，由于圆弧槽214的形状，则转轴221可以方便转动，便于实施推力，使插脚222沿着圆弧槽214滑动及转动。第一位置2141及第二位置2142分别位于圆弧槽214的两端，可以尽量减小圆弧槽214的长度，进而减小插头本体21的体积。
可以理解，在其他实施方式中，第一位置与第二位置还可以位于圆弧槽214的中间部位，则圆弧形凹面还可以位于圆弧槽214的中段区域。
为方便说明，圆弧槽214的一端对应为第一位置2141，另一端对应为第二位置2142。其中，第二位置2142靠近下壳213的一端的顶端210端面。其中，当转轴221位于圆弧槽214的第一位置2141，插头22位于收折状态。转轴221沿圆弧槽214滑动到第二位置2142，插头22相对于圆弧槽214转动，插头22的顶端210从过孔2121转出收容槽211，使插脚222转动至工作状态，转轴221位于第二位置2142上。插脚222位于工作状态的时候，插脚222与插头本体21的表面垂直，以保证插脚222能够稳定插入插座的插孔内。
在一些实施方式中，请再次参阅图2及图7，插脚222的底部设有连接件23。转轴221通过连接件23连接两插脚222，以使转轴221能够带动两个插脚222一起运动。
连接件23可以为塑料、橡胶等材料注塑而成。连接件23至少部分包覆插脚222的底部。连接件23对插脚222的底部可以起到绝缘保护的作用。并且，连接件23可滑动设于圆弧槽214上。连接件23包覆在插脚222的底部，插脚222不直接与圆弧槽214接触。连接件23及下壳213均为注塑成型的塑胶件，则连接件23与圆弧槽214之间具有较小的摩擦阻力，便于插脚222的滑动及转动。
并且，连接件23的底部为圆弧形。圆弧形的连接件23底部可以减小连接件23与圆弧槽214之间的接触面积，保证连接件23也能够顺利沿圆弧槽214滑动及转动。
由于插脚222至少设有两个，转轴221连接两个插脚222。通过位于中间的转轴221连接两插脚222，并使插脚222沿圆弧槽214滑动，可以使两插脚222保持一致运动轨迹，使两个插脚222保持同步运动。转轴221设有弧形的侧面。则弧形的侧面可以减小转轴221与圆弧槽214之间的接触面积，保证插脚222能够顺利沿圆弧槽214滑动及转动。
请参阅图5，在一些实施方式中，转轴221的横截面呈椭圆形。则转轴221在沿圆弧槽214滑动、转动的时候，椭圆形的长轴方向与圆弧槽214的延伸方向平行。请同时参阅图7，当转轴221运动到圆弧槽214的第二位置2142时候，转轴221转动使转轴221的外表面能够与圆弧槽214的内侧壁相互抵持，以固定支撑转轴221，保证插脚222能够稳定限位于圆弧槽214的第二位置2142处，保证插脚222能够稳定处于工作状态，正常使用。
请同时参阅图9，收容槽211的底部设有限位件。转轴转动至第一位置2141或第二位置2142，转轴221与限位件限位连接。
在一些实施方式中，圆弧槽214于靠近第一位置的位置处设有第一限位件2143。第一限位件2143设于收容槽211靠近第一位置处。插脚收折于收容槽内，转轴221与第一限位件2143限位抵持。第一限位件2143设有导向面。第一限位件2143的导向面可以方便插脚222从第一位置2141经第一限位件2143顺利滑动至第二位置2142。
限位件包括第二限位件2144。第二限位件2144设于收容槽211靠近第二位置2142处。具体地，圆弧槽214于靠近第二位置2142处设有第二限位件2144。转轴221转动至第二位置2142，转轴221与第二限位件2144限位抵持。
第二限位件2144也设有导向面，第二限位件2144的导向面在沿第一位置2141朝向第二位置2142的方向上平滑过渡，以方便转轴221沿圆弧槽214滑动，并顺利滑动至圆弧槽214的第二位置2142位置处，使插脚222保持工作状态。
并且，第一限位件2143及第二限位件2144为狭长形，沿平行于转轴221的轴向延伸。因此，第一限位件2143及第二限位件2144可以与转轴221之间具有较大的接触面积，保证第一限位件2143及第二限位件2144能够与转轴221保持稳定接触限位。
第一限位件2143与第二限位件2144相互交错设置，第一限位件2143及第二限位件2144分居圆弧槽214底面的相对两侧。
相对应地，请再次参阅图7，转轴221上设有凸筋。凸筋与限位件配合抵持限位。凸筋包括第一凸筋233及第二凸筋234。第一凸筋233及第二凸筋234相对交错设置，以分别对应与第一限位件2143及第二限位件2144抵持。
请参阅图10，当插脚222位于收折状态的时候，转轴221的第一凸筋233与圆弧槽214上的第一限位件2143相互抵持，使插脚222限位处于收折状态。转轴221沿圆 弧槽214滑动并转动，当转轴221运动至圆弧槽214的第二位置2142的时候，转轴221的第二凸筋234与圆弧槽214上的第二限位件2144相互配合抵接，使插脚222限位处于工作状态，如图11所示。
并且，收折状态的插脚222与工作状态的插脚222之间相互垂直。因此，转轴221上的第一凸筋233与第二凸筋234对应于转轴221的圆心角为90度，以保证转轴221能够转动90度，使插脚222可以从收折状态转动至垂直于收折状态的工作状态。
请再次参阅图2，在一些实施方式中，收容槽211远离第一位置2141的一端开设有通槽216。通槽216与插头本体21的外侧连通。转轴221位于第一位置2141，插脚222部分收容于通槽216内。具体地，通槽216设于圆弧槽214的第二位置2142处。通槽216沿圆弧槽214的延伸方向延伸。圆弧槽214通过通槽216与插头本体21的外侧连通，通槽216用于收容插头22。
并且，在一些实施方式中，通槽216可以由上壳212与下壳213共同围成。上壳212及下壳213上均开设有通槽216。
通槽216的槽口宽度小于过孔2121的槽口宽度。通槽216只需要收容部分插脚22通槽216的槽口宽度相对于收容槽211的槽口宽度较窄，以提高上述插头结构20的结构紧密性。
在一些实施方式中，收容槽211的长度小于插脚222的长度，插脚222的端部223凸伸出通槽216。当插脚222位于收折状态，即转轴221位于第一位置上的时候，插脚222的端部223位于插头本体21的外侧，方便手持插脚222用力使其转动。
并且，插头本体21通过设置通槽216，可以进一步保证插头本体21的收容槽211的长度较小，通过较小长度的收容槽211即可收容插脚222，使插脚222能够处于收折状态。避免插头结构20为了收容插脚222，设置较长的收容槽211，收容槽211的长度较长造成插头结构20占用的面积较大。
转轴221在圆弧槽214内运动的时候，插脚222既可以沿圆弧槽214沿其延伸方向相对滑动，也可以相对于圆弧槽214发生转动。并且，插脚222相对于圆弧槽214的滑动与转动的先后顺序并不做限定，插脚222可以先滑动再转动，也可以先转动再滑动。在一些实施方式中，插脚222在弧形的圆弧槽214内的相对运动，插脚222在滑动的同时发生转动。
请再次参阅图9，在一些实施方式中，收容槽211的两侧壁还设有第一导槽2115及第二导槽2116。第一导槽2115及第二导槽2116分别位于收容槽211的两侧。插脚222的外侧凸设有凸柱232。凸柱232与插脚222电连接。凸柱232可滑动设于第一导槽2115及第二导槽2116上。凸柱232沿第一导槽2115及第二导槽2116滑动，有助于转轴221能够稳定地滑动及转动。
凸柱232与转轴221位于同一轴线上。因此，第一导槽2115及第二导槽2116的形状相同。其中，第一导槽2115及第二导槽2116的高度为与凸柱232的高度位置相 适配，使凸柱232能够沿第一导槽2115及第二导槽2116滑动、转动。
并且，凸柱232为导体。凸柱232与插脚222电连接。凸柱232可以为金属凸柱。凸柱232在连接件23的内部与插脚222的底部实现电连接。
插头结构20于收容槽211内设于导电弹片24。导电弹片24设于收容槽211的内侧，且与插脚222相对设置。导电弹片24的一端与插脚222电连接。导电弹片24的另一端通过导线与充电模块10电连接。
请参阅图11及图12，具体地，导电弹片24安装于上壳212上。上壳212设有卡槽2122。导电弹片24的两端卡合固定于卡槽2122内。导电弹片24通过导线与主板11电连接。在一些实施方式中，上壳212于凸台215的两侧设有卡槽2122。
导电弹片24设有弹性部241。卡槽2122的形状与导电弹片24相适配，可以使弹性部241卡合于卡槽2122内，以限位导电弹片24。
请参阅图13，导电弹片24为两个，分别对应设于插脚222沿转轴231轴向的相对两侧。凸柱232相对于插脚222的两侧凸出，则便于凸柱232与导电弹片24相互接触，而实现电连接。
请同时参阅图14及图15，当插脚222转动至工作状态的时候，弹性部241受到凸柱232挤压会发生弹性形变，产生弹性回复力。具体地，导电弹片24为金属片弯折形成，弹性部241经弯折具有弹性。
当上壳212与下壳213相互对接的时候，上壳212的凸台215对应下壳213的圆弧槽214的位置，则导电弹片24正对应于插脚222的外侧。请参阅图8及图9，弹性部241对应于滑槽的第二位置2142。则凸柱232凸伸出于插脚222的外侧。当插脚222位于第二位置2142时，凸柱232与导电弹片24的弹性部241相互顶持，导电弹片24发生形变，因此，导电弹片24与插脚222实现电连接。
在上述插头结构20中，插脚222可以处于收折状态时候，收容于收容槽211内。当需要打开使用的时候，插脚222可以沿收容槽211滑动及转动，使插脚222伸出以供使用。因此，上述插头结构20在不使用的时候，插脚222收回，可以减小插脚222的占用空间，便于携带及收纳。
同时，在插脚222滑动至工作状态的过程中，插脚222的位置朝向插头本体21的边缘运动，减小插脚222与插头本体21边缘之间距离。因此，当上述插头结构20插接于插座上的时候，插头结构20占用的空间较小，不会“霸占”相邻位置处的插座空间。
在其他实施方式中，插头可以为二极带接地插，插头结构具有三个插脚。则三个插脚可以分为一个接地插脚与两个电极插脚。则两个电极插脚之间可以设置一转轴，插头本体的收容槽内也设有滑槽，则该转轴沿滑槽滑动及转动从而带动两个电极插脚运动。
接地插脚可以可转动设于插头本体上。当两个电极插脚处于收折状态的时候，接 地插脚也处于收折状态，接地插脚可以收容于两个电极插脚之间。当两个电极插脚处于工作状态的时候，接地插脚也处于工作状态，则该二极带接地插可以正常插接使用。
因此，该二极带接地插也可以减少占用体积，方便收纳携带。同时，该二极带接地插的边缘与插脚之间的距离也较小，不会占用相邻位置处的插座空间，其他插头的正常使用，避免发生“霸王插头”的现象。
请参阅图16，在其他实施方式中，电子设备还可以为移动电源。电路模块40还包括用于存储电能的储能单元41及充放电电路42。储能单元41与充放电电路42电连接。储能单元41与充放电电路42电连接。充放电电路42可以用于对储能单元41进行充电，储能单元41还可以通过该充放电电路42对外接用电装置进行供电。
在其他实施方式中，电路模块还可以为其他供电电路，供电电路与插头结构的插脚电连接，以通过插头结构接入外接电源，通过供电电路对用电装置进行供电。供电电路可以为变压转换电路等。电子设备可以为适配器、电源转换接头等。
并且，在其他实施方式中，电路模块与插头结构可拆卸连接。电路模块相对于插头结构可以为独立结构，电路模块与插头结构可以通过插接导线实现电连接。例如，电路模块为充电宝，插头结构可以为充电插头。充电宝可以与插头结构相互独立设置，以方便携带。
虽然已参照几个典型实施方式描述了本公开，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本发明能够以多种形式具体实施而不脱离发明的精神或实质，所以应当理解，上述实施方式不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
