所述第一导轨6包括固定外轨66、与所述固定外轨66滑动连接的支撑内轨61和设于所述固定外轨66与所述支撑内轨61之间的导向空间中的履带式导轨，该导向空间能够使得履带式导轨跟随支撑内轨61一起往复移动，所述履带式导轨可以包括环形封闭的轨带62和分别设于所述轨带62内长度方向两端的齿轮63，轨带62形成长圆形，当然两个齿轮63大小可以一样也可以不一样，所述轨带62的内表面排布有与所述齿轮63的轮齿啮合的内齿，从而当轨带62移动时带动齿轮63一起移动，轨带62移动的距离等于齿轮63滚动的线性距离，所述轨带62位于移动方向的一侧即长圆形的一条长边通过固定件64与所述支撑内轨61固定连接，该固定件64可以采用塑料件，呈块状，其结构不做具体限定，所述支撑内轨61的外侧固定有沿其长度方向设置的线卡5，线卡5被配置为固定走线的位置；
所述同步滚轮3与其中一个所述齿轮63同轴固定连接，所述同步滚轮3的轴向外周设有线束槽32；
所述第一导轨6被配置为安装在冰箱的箱体7内设有接线端的一侧，所述固定外轨66被配置为与所述箱体7的内侧壁固定连接，所述支撑内轨61被配置为与所述抽屉门体的(相应)侧壁固定连接，供电线束4的一端被配置为与所述箱体7的接线端固定连接，所述供电线束4的另一端绕入所述线束槽32并依次通过所述线卡5固定后与所述抽屉门体的接线端固定连接，安装后支撑内轨61与抽屉门体为一体结构，当抽屉门体开门或关门时，支撑内轨61同步向前或向后移动，支撑内轨61带着轨带62同步移动，由于齿轮63与轨带62啮合，轨带62移动的距离为齿轮63滚动的线性距离，供电线束4随同步滚轮3及齿轮63同步运动，因此供电 线束4移动的距离等于齿轮63滚动的线性距离，从而供电线束4在移动过程中不会有多余长度，可以很好的减少供电线束4的磨损，有效的保护消费者的安全。
本公开实施例中，具体地，为了便于支撑内轨61移动，合理布置支撑内轨61与轨带62的位置，所述支撑内轨61的上侧下表面通过所述固定件64与所述轨带62位于移动方向的上侧固定连接。
本公开实施例中，所述轨带62位于移动方向的下侧通过导向件65可移动地与所述固定外轨66的下侧上表面连接，导向件65的设置既能保证轨带62顺利移动，也能起到导向的作用，避免轨带62往复移动过程中偏离原有轨道。
本公开实施例中，为了便于同步滚轮3安装，避免发生干涉，两个所述齿轮63中，靠近所述固定外轨66后端的所述齿轮63外露出所述支撑内轨61，所述同步滚轮3与外露的所述齿轮63同轴固定连接。
本公开实施例中，如图7所示，所述同步滚轮3包括滚轴31和沿所述滚轴31外的轴向间隔设置的一对轮盘34，一对所述轮盘34之间形成所述线束槽32，具体为一对轮盘34之间的滚轴31与一对轮盘34共同限定出该线束槽32，线束槽32被配置为过线。
本公开实施例中，具体地，与所述同步滚轮3连接的所述齿轮63的轴向设有连接孔，所述滚轴31的一端插入所述连接孔与所述连接孔孔轴配合连接，拆装方便，省时省力。
本公开的优化实施例，所述滚轴31与所述齿轮63连接的一端为非圆轴，所述连接孔为与所述非圆轴匹配的非圆孔，非圆轴与非圆孔配合连接后能够实现更精准的同步转动和扭矩传递，不会出现滚轴31与齿轮63的连接孔之间出现打滑的情况，从而可以降低对装配精度的要求，从而节省成本。
本公开实施例中，所述滚轴31与所述齿轮63连接的相对另一端设置为连接套33，便于与外部的轴或杆类部件连接。
本公开实施例中，一对所述轮盘34之间的间距大于等于所述供电线束4的外径，以便于供电线束4在线束槽32中顺畅移动，一对所述轮盘34被配置为与所述箱体7的底面滚动接触，从而为第一导轨6提供支撑力， 使得第一导轨6的往复移动更加平稳。
本公开实施例中，如图8所示，所述线卡5沿其长度方向设有开口槽51，所述开口槽51的内表面与所述供电线束4的外表面相匹配，当供电线束4从开口槽51的开口卡入开口槽51中后位置即被固定；所述线卡5与所述支撑内轨61一体设置或分体设置，可以在制造支撑内轨61时自带线卡5，也可以通过后期安装线卡5，本公开实施例不做具体限定。
本公开实施例中，如图5和图6所示，还包括第二导轨1和同步杆2，所述同步杆2的两端分别与所述第一导轨6的同步滚轮3以及第二导轨1的相对端固定连接，同步杆2与同步滚轮3连接的一端直接插接在同步滚轮3轴向的所述连接套33中，同步杆2与第二导轨1连接的一端直接插接在第二导轨1后端侧面设置的插孔中，确保同步杆2安装快速、可靠，拆卸方便，将组装后的第一导轨6、第二导轨1和同步杆2组成的连线结构安装在冰箱的箱体7与抽屉门体之间即可；用于实现供电线束4在移动过程中，无冗余、无挤压、无变形。
如图9和图10所示，本公开实施例还提供一种冰箱，包括箱体7、供电线束4和上述技术方案所述的冰箱抽屉组件；所述抽屉门体可抽动地设于所述箱体7内，所述第一导轨6与所述第二导轨1相对设于所述箱体7与所述抽屉门体之间的两侧，所述同步杆2的两端分别与所述第一导轨6的同步滚轮3以及第二导轨1的后端固定连接，所述箱体7内位于所述第一导轨6侧设有接线端，所述固定外轨66与所述箱体7的内侧壁固定连接，所述支撑内轨61与所述抽屉门体的(相应)侧壁固定连接，所述供电线束4的一端与所述箱体7的接线端固定连接，所述供电线束4的另一端绕入所述线束槽32并通过所述线卡5固定后与所述抽屉门体的接线端固定连接。当抽屉门体开门或关门时，支撑内轨61同步向前或向后移动，支撑内轨61带着轨带62同步移动，由于齿轮63与轨带62啮合，轨带62移动的距离为齿轮63滚动的线性距离，即轨带62移动的直线距离与齿轮63滚过的周向距离相等，供电线束4随同步滚轮3及齿轮63同步运动，因此供电线束4移动的距离等于齿轮63滚动的线性距离，从而供电线束4在移动过程中始终紧绷不会有多余长度，可以很好的减少供电线束4的磨损，有效的保护消费者的安全。
本公开实施例中，如图11所示，所述箱体7的底部设有过线孔71，所述供电线束4穿过所述过线孔71与所述箱体7的接线端连接，所述供电线束4由下至上从所述线束槽32的后方绕入所述线束槽32，便于供电线束4走线。
由以上实施例可以看出，本公开实施例在抽拉式门体移动过程中，供电线束不会有多余的长度，可以很好的减少供电线束的磨损漏电，有效的保护消费者的安全。
以上所述仅为本公开的较佳实施例而已，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
