分别可滑动地设置在滑轨中轨的上表面和下表面的上珠巢部件和下珠巢部件；
所述上珠巢部件具有多个贯穿的上滚珠槽；
所述下珠巢部件具有多个贯穿的下滚珠槽；
所述上滚珠槽内转动固定有分别与所述滑轨中轨和所述滑轨上轨相接的滚珠；
所述下滚珠槽内转动固定有分别与所述滑轨中轨和所述滑轨下轨相接的滚珠。
可选地，滑轨组件还包括：
底座，与滑轨下轨的下表面固定连接，并用于滑轨组件的支撑物相连。
根据本发明的另一个方面，还提供了一种冰箱，包括：
储物间室；
两个根据上述任一项滑轨组件，两个滑轨组件分别固定在储物间室的两侧；
储物容器，分别与两个滑轨组件的上轨齿条的上表面固定连接。
在本发明的滑轨组件中，下轨齿条和上轨齿条与齿轮分别为啮合连接。在外力的作用下，滑轨上轨带动上轨齿条滑动，从而通过上轨齿条带动齿轮转动，进而在齿轮的转动下带动滑轨中轨沿滑轨下轨滑动。通过下轨齿条和上轨齿条与齿轮分别啮合连接，使得滑轨上轨和滑轨中轨的运动更加可控，减轻了滑轨中轨与滑轨下轨和滑轨上轨之间的摩擦和碰撞，从而降低了噪声。并且，齿轮分别与滑轨上轨和滑轨下轨面面接触，可以维持滑轨上轨和滑轨下轨的相对位置，从而减少滑轨上轨的左右晃动量，避免滑轨上轨和周围的物体发生碰撞产生噪声，也使滑轨上轨在外力的作用下更加容易的被拉出和回推。
进一步地，在本发明的滑轨组件中，滑轨上轨在外力作用下沿滑轨中轨滑动，并通过上轨齿条带动齿轮转动，从而在齿轮的转动下带动滑轨中轨沿滑轨下轨滑动的过程中，由于下轨齿条一直处于静止的状态，滑轨上轨相对滑轨下轨滑动的滑动距离大于齿轮相对滑轨下轨滑动的滑动距离。因此，在滑轨上轨滑动较大距离的时候，齿轮没必要经过整个滑轨下轨，所以下轨齿条的长度可以小于滑轨下轨的长度。同理，上轨齿条的长度可以小于滑轨上轨的长度。下轨齿条的长度小于滑轨下轨的长度，上轨齿条的长度小于滑轨上轨的长度，可以节省材料，进而节约了成本。
进一步地，在本发明的滑轨组件中，在下轨齿条的长度小于滑轨下轨的长度以及上轨齿条的长度小于滑轨上轨的长度的情况下，将下轨齿条设置在滑轨下轨的朝向拉出方向的一端，上轨齿条设置在滑轨上轨的朝向回推方向的一端，可以使滑轨上轨滑动更大的距离。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具 体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：

具体实施方式
图1是根据本发明一个实施例的滑轨组件100的结构示意图，参见图1。该滑轨组件100可包括滑轨下轨101、滑轨中轨103、滑轨上轨104以及齿轮106。滑轨下轨101上设置有下轨齿条102。滑轨中轨103位于滑轨下轨101的上方，且可滑动地与滑轨下轨101连接。滑轨上轨104上设置有上轨齿条105，滑轨上轨104位于滑轨中轨103的上方，且可滑动的与滑轨中轨103连接。齿轮106可转动地设置在滑轨中轨103上，且齿轮106分别与上轨齿条105和下轨齿条102啮合相连。滑轨上轨104适于在外力作用下沿滑轨中轨103滑动，并通过上轨齿条105带动齿轮106转动，从而在齿轮106的转动下带动滑轨中轨103沿滑轨下轨101滑动。
在本实施例的滑轨组件100中，下轨齿条102处于静止的状态(被固定的状态)。下轨齿条102和上轨齿条105与齿轮106分别为啮合连接。在外力的作用下，滑轨上轨104带动上轨齿条105滑动，从而通过上轨齿条105带动齿轮106转动，进而在齿轮106的转动下带动滑轨中轨103沿滑轨下轨101滑动。通过下轨齿条102和上轨齿条105与齿轮106分别啮合连接，使得滑轨上轨104和滑轨中轨103的运动更加可控，减轻了滑轨中轨103与滑轨下轨101和滑轨上轨104之间的摩擦和碰撞，从而降低了噪声。并且，齿轮106分别与滑轨上轨104和滑轨下轨101面面接触，可以维持滑轨上轨104和滑轨下轨101的相对位置，从而减少滑轨上轨104的左右晃动量，避免滑轨上轨104和周围的物体发生碰撞产生噪声，也使滑轨上轨104在外力的作用下更加容易的被拉出和回推。
在本发明一个实施例中，下轨齿条102的长度小于滑轨下轨101的长度。上轨齿条105的长度小于滑轨上轨104的长度。
在本实施例中，滑轨上轨104在外力作用下沿滑轨中轨103滑动，并通过上轨齿条105带动齿轮106转动，从而在齿轮106的转动下带动滑轨中轨103沿滑轨下轨101滑动的过程中，由于下轨齿条102一直处于静止的状态，滑轨上轨104相对滑轨下轨101滑动的滑动距离大于齿轮106相对滑轨下轨101滑动的滑动距离。具体地，例如，滑轨上轨104相对滑轨下轨101的滑动距离可以是齿轮106相对滑轨下轨101的滑动距离的2倍，即滑轨上轨104相对滑轨下轨101的滑动距离可以是滑轨中轨103相对滑轨下轨101的滑动距离的2倍。因此，在滑轨上轨104滑动较大距离的时候，齿轮106没必要经过整个滑轨下轨101，所以下轨齿条102的长度可以小于滑轨下轨101的长度。同理，上轨齿条105的长度可以小于滑轨上轨104的长度。下轨齿条102的长度小于滑轨下轨101的长度，上轨齿条105的长度小于滑轨上轨104的长度，可以节省材料，进而节约了成本。
在本发明一个实施例中，下轨齿条102可以设置在滑轨下轨101的朝向拉出方向的一端。上轨齿条105可以设置在滑轨上轨104的朝向回推方向的一端。
在本实施例中，如图1所示，图1中滑轨组件100的结构示意图为滑轨上轨104被回推后的结构示意图，回推后的状态也可以理解为复位状态。在下轨齿条102的长度小于滑轨下轨101的长度以及上轨齿条105的长度小于滑轨上轨104的长度的情况下，将下轨齿条102设置在滑轨下轨101的朝向拉出方向的一端，上轨齿条105设置在滑轨上轨104的朝向回推方向的一端，可以使滑轨上轨104滑动更大的距离。在本实施例中，下轨齿条102与上轨齿条105的长度之和可以大于或等于滑轨下轨101的长度。齿轮106可以设置在下轨齿条102与上轨齿条105相交错的部分所对应的滑轨中轨103的位置。下轨齿条102与上轨齿条105的长度可以相同，当然，也可以不相同，本发明实施例对此不做具体地限定。
在本发明一个实施例中，下轨齿条102、齿轮106以及上轨齿条105设置于滑轨下轨101、滑轨中轨103以及滑轨上轨104的相同侧的侧面上。下轨齿条102的各个齿位于下轨齿条102的上表面。上轨齿条105的各个齿位于上轨齿条105的下表面。
参见图1至图4，在本发明一个实施例中，滑轨上轨104的设置有上轨齿条105的侧面上具有第一凸起107。上轨齿条105具有与第一凸起107相 适配的第一卡槽108。滑轨下轨101的设置有下轨齿条102的侧面上具有第二凸起109。下轨齿条102具有与第二凸起109相适配的第二卡槽110。第一凸起107位于第一卡槽108中。第一凸起107用于使上轨齿条105固定在滑轨上轨104上。第二凸起109位于第二卡槽110中。第二凸起109用于使下轨齿条102固定在滑轨下轨101上。
在本发明一个实施例中，第一凸起107可以朝拉出方向弯折呈钩状结构。第二凸起109可以朝回推方向弯折呈钩状结构。钩状结构的第一凸起107和第二凸起109可以使上轨齿条105以及下轨齿条102更加稳定的固定在滑轨上轨104和滑轨下轨101上。
在本发明一个实施例中，滑轨上轨104的设置有上轨齿条105的侧面的朝向回推方向的一端具有第三卡槽111。上轨齿条105具有与第三卡槽111相适配的第三凸起112。滑轨下轨101的设置有下轨齿条102的侧面的朝向拉出方向的一端具有第四卡槽113。下轨齿条102具有与第四卡槽113相适配的第四凸起114。第三凸起112位于第三卡槽111中。第三凸起112用于使上轨齿条105固定在滑轨上轨104上。第四凸起114位于第四卡槽113中。第四凸起114用于使下轨齿条102固定在滑轨下轨101上。
在本发明一个实施例中，滑轨组件100还可包括分别可滑动地设置在滑轨中轨103的上表面和下表面的上珠巢部件115和下珠巢部件116。上珠巢部件115具有多个贯穿的上滚珠槽117。下珠巢部件116具有多个贯穿的下滚珠槽118。上滚珠槽117内转动固定有分别与滑轨中轨103和滑轨上轨104相接的滚珠(图中未示出)。下滚珠槽118内转动固定有分别与滑轨中轨103和滑轨下轨101相接的滚珠。
在本实施例中，滑轨上轨104在外力作用下沿滑轨中轨103滑动的过程中，可以带动上珠巢部件115上的滚珠转动，从而减少滑轨上轨104和滑轨中轨103之间的摩擦阻力，减少了噪声，也使滑轨上轨104的运动更加平稳。滑轨中轨103在沿滑轨下轨101滑动的过程中，可以带动下珠巢部件116上的滚珠转动，从而减少滑轨中轨103和滑轨下轨101之间的摩擦阻力，减少了噪声，也使滑轨中轨103的运动更加平稳。
在本发明一个实施例中，滑轨组件100还可包括底座119。底座119与滑轨下轨101的下表面固定连接，并用于滑轨组件100的支撑物相连。
参见图5，基于同一构思，本发明还提供了一种冰箱200。该冰箱200 可包括储物间室201、储物容器202以及两个根据上述任一项实施例的滑轨组件100。两个滑轨组件100分别固定在储物间室201的两侧。储物容器202分别与两个滑轨组件100的上轨齿条105的上表面固定连接。
在本实施例中，储物间室201可以为冷冻室、冷藏室等。储物容器202可以为抽屉。储物容器202在外力的作用下，滑轨上轨104带动上轨齿条105滑动，从而通过上轨齿条105带动齿轮106转动，进而在齿轮106的转动下带动滑轨中轨103沿滑轨下轨101滑动，将储物容器202从储物间室201中拉出或回推。通过下轨齿条102和上轨齿条105与齿轮106分别啮合连接，使得滑轨上轨104和滑轨中轨103的运动更加可控，减轻了滑轨中轨103与滑轨下轨101和滑轨上轨104之间的摩擦和碰撞，从而降低了噪声。并且，齿轮106分别与滑轨上轨104和滑轨下轨101面面接触，可以维持滑轨上轨104和滑轨下轨101的相对位置，从而减少滑轨上轨104的左右晃动量，避免滑轨上轨104和储物间室201发生碰撞产生噪声，也使储物容器202以更加容易的被拉出和回推。另外，储物容器202在推拉的过程中，采用齿轮齿条结构的两个滑轨组件100可以同步运动，避免了两个滑轨组件100移动不一致导致的扭曲变形和左右晃动等问题。
在一些其他实施例中，滑轨组件100也可以应用于衣柜、办公桌等物品上，本发明实施例对此不做具体地限定。
上述各个实施例可以任意组合，根据上述任意一个优选实施例或多个优选实施例的组合，本发明实施例能够达到如下有益效果：
在本实施例的滑轨组件100中，下轨齿条102和上轨齿条105与齿轮106分别为啮合连接。在外力的作用下，滑轨上轨104带动上轨齿条105滑动，从而通过上轨齿条105带动齿轮106转动，进而在齿轮106的转动下带动滑轨中轨103沿滑轨下轨101滑动。通过下轨齿条102和上轨齿条105与齿轮106分别啮合连接，使得滑轨上轨104和滑轨中轨103的运动更加可控，减轻了滑轨中轨103与滑轨下轨101和滑轨上轨104之间的摩擦和碰撞，从而降低了噪声。并且，齿轮106分别与滑轨上轨104和滑轨下轨101面面接触，可以维持滑轨上轨104和滑轨下轨101的相对位置，从而减少滑轨上轨104的左右晃动量，避免滑轨上轨104和周围的物体发生碰撞产生噪声，也使滑轨上轨104在外力的作用下更加容易的被拉出和回推。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明 的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
