具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图对本发明的具体实施方式进行详细说明。这些优选实施方式的示例在附图中进行了例示。附图中所示和根据附图描述的本发明的实施方式仅仅是示例性的，并且本发明并不限于这些实施方式。
本文使用的例如“左”、“右”、“左侧”、“右侧”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个部件相对于另一个部件的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。例如，如果将图中的设备翻转，则被描述为位于其他单元或特征“右侧”的单元将位于其他单元或特征“左侧”。因此，示例性术语“右侧”可以囊括左侧和右侧这两种方位。设备可以以其他方式被定向(旋转90度或其他朝向)，并相应地解释本文使用的与空间相关的描述语。
参图1所示，本发明一具体实施方式中的左右开门机构包括设于冰箱门体上的铰链模块100以及设于冰箱箱体上的传动模块200，铰链模块100与传动模块200通过两端设置的铰链及齿轮等部件进行安装，当铰链模块100与传动模块200至少有一端可旋转固定，以实现冰箱的左侧开门或右侧开门。
结合图2、图3所示，本实施方式中的传动模块200包括传动底板21、位于传动底板上相对设置的两个第一齿轮22、通过第一齿轮传动的传动齿条23、以及分别与第一齿轮进行传动的第二齿轮24，第二齿轮24对传动齿条23进行导向和限位；铰链模块100包括铰链底板11及设于铰链底板上相对设置的两个铰链12，铰链12与第一齿轮22进行传动，当两个铰链12均与第一齿轮22啮合时，门体锁紧，当一侧铰链12与第一齿轮22脱离时，另一侧铰链与第一齿轮保持啮合，门体开启。
以下结合铰链模块及传动模块中的具体部件对本实施方式中的左右开门机构作详细说明。
参图4所示，本实施方式传动模块200包括纵长形的传动底板21，传动底板21上左右两侧分别设有第一转轴211和第二转轴212，第一转轴211位于第二转轴212的外侧，第一齿轮22和第二齿轮24分别通过第一转轴211和第二转轴212旋转安装于传动底板21上，且第一齿轮22和第二齿轮24相互啮合设置。
结合图5所示，第一齿轮22呈圆形设置，其通过第一转轴211旋转安装于传动底板21上，第一转轴211安装于第一齿轮22的中心位置。第一齿轮22包括用于与铰链啮合的第一齿状部221、以及用于与第二齿轮和传动齿条啮合的第二齿状部222。
应当理解的是，本实施方式中的第一齿轮22外侧包括相互分离的第一齿状部221和第二齿状部222，在其他实施方式中也可以将第一齿状部221和第二齿状部222设置为一个整体，同样可以达到与铰链、第二齿轮及传动齿条传动的目的。
第二齿轮24呈扇形设置，其通过第二转轴212旋转安装于传动底板21上，第二转轴212安装于第二齿轮24的非中心位置。第二齿轮24包括用于与第一齿轮啮合的第三齿状部241，第三齿状部241设于第二齿轮24的扇形面上，在第二齿轮24的顶部还设有滑槽242，滑槽242大致呈圆弧状设置。
本实施方式中第二齿轮24的高度高于第一齿轮22的高度，而滑槽242的底面与第一齿轮22的顶面等高设置，且滑槽242为开口设置，如此可以快速进行传动齿条23与第二齿轮24的装配。当然，在其他实施方式中滑槽也可以为非开口设置，第一齿轮22和第二齿轮24的高度也可以相等或第一齿轮22的高度高于第二齿轮24的高度，此处不再一一举例进行详细说明。
传动齿条23为纵长形设置，传动齿条23的两端分别设有与第一齿轮啮合的第四齿状部231，第四齿状部231与第一齿轮22上的第二齿状部222相互啮合。进一步地，传动齿条上设有限位件232，限位件232与第二齿轮24的顶面垂直设置，当第一齿轮和第二齿轮啮合转动时，传动齿条跟随第一齿轮转动，其上的限位件232在第二齿轮24上的滑槽242内运动。
本实施方式中传动齿条23的高度高于第一齿轮22及第二齿轮24的高度，如此可以将传动齿条23的限位件232垂直装配于第二齿轮24上的滑槽242内。
进一步地，为了保持传动齿条23和第一齿轮22的固定，第一齿轮22在第二齿状部222的旁侧还还设有收容槽223，传动齿条23在第四齿状部231的外侧设有固定部233，固定部233与收容槽223的形状对应设置，当传动齿条23与第一齿轮22通过第二齿状部222与第四齿状部231啮合后，固定部233固定收容于该收容槽223中，以起到固定传动齿条端部的效果。
参图6所示为传动模块的装配示意图，传动模块的装配及传动原理具体如下：
第一齿轮22和第二齿轮24分别通过第一转轴211和第二转轴212旋转安装于传动底板21的端部，传动底板21的两侧均分别设有一对第一齿轮22和第二齿轮24，第一齿轮22和第二齿轮24通过第二齿状部222和第三齿状部241相互啮合，当第一齿轮22沿第一转轴211转动时，能够带动第二齿轮24沿第二转轴212转动；
同时，传动齿条23与两个第一齿轮22分别通过第二齿状部222和第四齿状部231相互啮合，当一侧的第一齿轮22转动时，能够带动传动齿条23水平移动，从而传动齿条能够带动另一侧的第一齿轮22相同的方向进行转动。为了保证传动齿条23与第一齿轮22的相对位置，通过传动齿条23端部的固定部233与第一齿轮22上的收容槽223对其进行限位。
在传动齿条23的传动过程中，传动齿条23上的限位件232始终位于第二齿轮24上的滑槽242内，以保证传动齿条23不脱离传动位置，由于第二齿轮沿第二转轴旋转运动，同时传动齿条沿直线传动，滑槽242的形状大致设置为圆弧形，且滑槽242设置于第二转轴与第三齿状部之间，以提供传动齿条23上限位件232的滑动轨道。
优选地，参图1、图3所示，本实施方式中为了对传动齿条23的传动线路进行限制，传动底板21上在两个第二齿轮之间还设有导滑件213，导滑件213上设有用于对传动齿条沿传动方向进行导向的导滑槽214。本实施方式中导滑件213通过若干螺母固定于传动底板21上，当然其他实施方式中也可以通过卡扣等安装方式进行安装，或传动底板与导滑件一体成型设置，此处不再一一举例进行说明。
再参图7所示，本实施方式中的铰链模块100包括纵长形的铰链底板11，铰链底板11的两端设有对称分布的第三转轴111，每个第三转轴111上均旋转安装有一个用于连接铰链底板与传动模块的铰链。
结合图8所示，铰链12包括铰链本体121及自铰链本体121向外延伸的延伸部122，铰链本体121旋转安装于铰链底板11上，延伸部122的端部侧面设有第五齿状部123，铰链12上的第五齿状部123与传动底板21上第一齿轮22的第一齿状部221相互啮合。
当用户从一侧开门时，拉动一侧的铰链模块，此时，该侧的铰链12通过第五齿状部123向外运动，第五齿状部123与第一齿状部221相互啮合，带动传动模块上的第一齿轮22围绕第一转轴211转动，当铰链12向外运动一段距离后，第五齿状部123与第一齿状部221相互分离，即铰链12会与第一齿轮22相互分离，第一齿轮22停止转动，另一侧的铰链与铰链本体可旋转设置，从而可以达到单侧开门的目的。
进一步地，参图6所示，本实施方式中在传动底板21的两端固定设有开槽215，开槽215用于对延伸部进行限位，开槽215通过卡扣的方式形成，当铰链12与第一齿轮22相对运动时，铰链12沿着开槽215方向(垂直于传动齿条的运动方向)进行运动。
以下结合图9、图10所示，以左侧开门为例对本实施方式进行进一步说明。
参图9并结合图1-8所示，左右开门机构处于锁紧状态，铰链模块与传动模块相互卡合，铰链12旋转安装于铰链底板11上，第一齿轮22、第二齿轮24、传动齿条23安装于传动底板21上。左侧的铰链12通过前端的第五齿状部123与第一齿轮22上的第一齿状部221相互啮合，第一齿轮22的第二齿状部222与第二齿轮24的第三齿状部241相互啮合，同时，传动齿条23左端的第四齿状部231与第一齿轮22的第一齿状部221未啮合，传动齿条23左端固定部233位于第一齿轮22上的收容槽223内，传动齿条23的限位件232垂直装配于第二齿轮24上的滑槽242内。同样地，左右开门机构右侧的装配关系与左侧对称设置，此处不再进行赘述。
从左侧开门时，拉动左侧的铰链底板11，带动左侧的铰链12向外运动，左侧的铰链12通过第五齿状部123与第一齿状部221的啮合带动第一齿轮22逆时针运动，第一齿轮22上第二齿状部222与传动齿条23上的第四齿状部231相啮合，进而带动传动齿条23向左运动。同时，第一齿轮22的第二齿状部222与第二齿轮24的第三齿状部241相互啮合，第一齿轮22可带动第二齿轮24顺时针转动，传动齿条23上的限位件232沿滑槽242向左运动。
传动齿条23向左运动时，传动齿条23右侧的第四齿状部231会带动右侧的第一齿轮22同时作顺时针转动，第一齿轮22同时带动右侧的第二齿轮24顺时针转动，右侧的铰链12向内运动。
可见，左侧的铰链12逐渐向外运动至铰链12脱离左侧的第一齿轮22，左侧的左右开门机构处于打开状态，其结构参图10所示，此时，右侧的铰链12逐渐向内运动，与右侧的第一齿轮22进一步锁紧，右侧铰链底板上的第三转轴作为中心轴供冰箱门体转动。
当从左侧锁门时，推动门体左侧，左侧的铰链12向内运动直至铰链12第一齿轮22逐渐啮合，此时左侧的第一齿轮22、第二齿轮24、及传动齿条23的传动方向与开门时相反，传动齿条23逐渐向右运动，直至冰箱门体与冰箱箱体贴合，此时左右开门机构的状态恢复至图1和图9中所示状态。
同样地，当左右开门机构从右侧开门时，右侧的铰链向外运动，此时左侧的铰链会反方向向内运动逐渐锁紧，左侧铰链底板上的第三转轴作为中心轴供冰箱门体转动；当从右侧锁门时，右侧的铰链向内运动，传动齿条逐渐向左运动，直至其状态恢复至锁紧状态。右侧开门或锁门时左右开门机构的传动关系与左侧开门或锁门相类似，此处不再进行赘述。
本实施方式中的左右开门机构以冰箱为例进行说明，在其他实施方式中该左右开门机构可以适用于任何包括门体和箱体的装置，如酒柜等，此处不再进行详细说明。
由以上技术方案可以看出，本发明具有以下有益效果：
旋转轴设置于门体上，在不进行任何调整的情况下，可以同时实现左侧开门和右侧开门；
保证了门体开启和关闭过程顺畅，无阻塞感，无撞击异响，并且过程中门体不存在脱落的危险，同时给用户带来极好的使用体验。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本申请的可行性实施方式的具体说明，它们并非用以限制本申请的保护范围，凡未脱离本申请技艺精神所作的等效实施方式或变更均应包含在本申请的保护范围之内。
