Description

抽屉滑动机构及具有其的冰箱
本申请要求了申请日为2016年07月15日，申请号为201610562777.6，发明名称为“抽屉滑动机构及具有其的冰箱”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及制冷领域，尤其涉及一种抽屉滑动机构及具有其的冰箱。
背景技术
目前，市场上冰箱简易抽拉的果蔬盒(或抽屉)与冰箱箱体之间预留有一定的间隙，以便果蔬盒(或抽屉)进出。但是，这种间隙的设计会带来很多问题，主要包括以下两点：(1)当用户拉出或推进果蔬盒(或抽屉)的作用力没有在果蔬盒(或抽屉)深度中心线时，因为没有机构辅助校正，会造成果蔬盒(或抽屉)逐渐偏移深度中心线，当继续拉出或关闭一定距离后，会造成果蔬盒(或抽屉)一端与冰箱箱体内胆发生碰撞，从而产生噪音；(2)当碰撞发生时，同时也会引起拉出或推进过程的不顺畅，此时需要改变作用力的方向，否则无法继续进行拉出或推进操作。
现有技术中，通过在果蔬盒(或抽屉)的门体面板上设计凹陷结构，以暗示用户将手放在凹陷结构处以完成拉出或推进操作。凹陷结构的位置在深度中心线和水平中心点交接的地方，如此，在拉出或推进过程的顺畅度上有一定的改善，但不能消除用户作用力偏移产生的影响，因此，仍然不能很好地解决上述问题。
发明内容

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
如图1至图4所示，本发明一实施方式的冰箱(未图示)包括箱体200，所述箱体200内活动设置有抽屉100，抽屉100的数量不限。
本发明一实施方式提供了一种用于抽屉100在箱体200内拉出或推进的滑动机构，包括相对设置的两组滑动组件10。当然，所述滑动机构也可以用于其他结构的抽拉、扩展或收缩。需要说明的是，两组滑动组件10可以左右设置，在其他实施例中，两组滑动组件10也可以上下设置，在本发明中，以两组滑动组件左右设置为例。
另外，本文使用的例如“上”、“上方”、“下”、“下方”、“左”、“右”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单元或特征相对于另一个单元或特征的关系。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“下方”或“之下”的单元将位于其他单元或特征“上方”。因此，示例性术语“下方”可以囊括上方和下方这两种方位。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。
本发明一实施方式的滑动机构用于辅助抽屉100在箱体200内拉出或推进。
滑动机构包括相对设置的第一滑动组件10a和第二滑动组件10b，第一滑动组件10a及第二滑动 组件10b分别设置于所述抽屉100的两侧，以辅助所述抽屉100同步进出。
每一滑动组件10包括相互配合的滑条20及滑槽30，所述滑条20设于所述抽屉100的侧边，所述滑槽30设于箱体200内胆处。
每一滑动组件10还包括相互配合的齿条40及齿轮组件50。
所述齿条40位于所述抽屉100的侧边，所述齿轮组件50位于箱体200内胆处。
其中，所述齿轮组件50包括可原地转动的齿轮51，当抽屉100在箱体200内拉出或推进时，所述齿轮51始终与所述齿条40齿合。
这里，滑条20及滑槽30的配合可以初步实现抽屉100推进或拉出过程不偏离，同时实现抽屉100左右两边同步进出。但是，需要注意的是，此时左右两侧滑条20及滑槽30配合结构的运动路径实质是左右两条平行线，其对抽屉100的支撑作用并不理想，抽屉100在推进或拉出过程中仍会出现偏移或不同步等现象。
在本实施方式中，在滑条20及滑槽30的基础上，每一滑动组件10还包括相互配合的齿条40及齿轮组件50，当齿条40随着抽屉100移动时，齿轮组件50的齿轮51始终与所述齿条40齿合，如此，齿轮51与齿条40之间实现另一支撑点，与滑条20及滑槽30的线性支撑配合，实现对抽屉100的三角支撑作用。
可以理解，当用户作用力出现偏离深度中心线时，滑条20与滑槽30的配合、以及齿轮51与齿条40的配合可以辅助调整整个抽屉100拉出或推进过程的方向，很好地解决了抽屉100拉出或推进过程发生偏移而具有噪音、抽屉100拉出或推进过程不顺畅、抽屉100左右部分不同步的问题。
在本实施方式中，所述齿条40的延伸方向平行于滑条30的延伸方向，两者的延伸方向均为抽屉100推进方向，以控制抽屉100的推进或拉出方向。
齿轮组件50靠近箱体200的开口部设置。
进一步地，在本实施方式中，结合图5至图7，于抽屉100推进方向上，所述齿条40的末端具有斜面41，所述齿条40最靠近所述斜面41的齿为第一齿42。
所述滑槽30上设置有下限位件31，当所述抽屉100推进且所述滑条20与所述下限位件31相互干涉时，所述第一齿42与所述齿轮51齿合。
滑条20的末端形成有让位部21，当所述抽屉100推进时，让位部21最先与所述下限位件31相互干涉。
这里，当用户将抽屉100装入箱体200时，左右两侧滑条20的对位部21均会进入相应的滑槽30中，一般情况下，通过用户的细微调节，可以保证左右两侧的对位部21同时与相应的下限位部31干涉。即使没有同时干涉，由于下限位部31对对位部21具有一定强度的阻挡作用，当一侧的下限位部31与对位部21相互干涉而另一侧未相互干涉时，可以在一侧保持相互干涉的情况下，调整另一侧的对位部21，使其也与对应的下限位部31相互干涉。
由于左右两侧的对位部21同时与相应的下限位部31干涉，也就是说，左右两侧齿条40的第一齿42同时与对应的齿轮51齿合，如此，可以保证左右两侧的齿条40同步移动，从而进一步辅助抽屉100左右两侧同步移动，抽屉100不会发生偏移。
另外，所述滑槽30还包括上限位件(未标示)，抽屉100上具有一凸部(未标示)，当用户需要将抽屉100拉出一段距离后，凸部会与上限位部相互干涉，此时需要将抽屉100抬起一个角度的同时继续向外拉出才能取出抽屉100，上限位部控制了抽屉100的极限拉出位置。
进一步地，在本实施方式中，所述齿轮组件50还包括调节组件52，所述调节组件52用于控制所述齿轮51沿第一方向X运动以使齿轮51始终与所述齿条40齿合，所述第一方向X为抽屉两侧齿条40的其中之一齿条40朝向其中另一齿条40的方向，即第一方向X为水平方向，第一方向X包括齿轮51朝向或远离齿条40的方向。
这里，齿轮51可以朝向或远离齿条40运动，但始终保持齿轮51与齿条40相互齿合。当抽屉 100推进或拉出过程发生偏移时，齿轮51始终给予齿条40朝向第一方向X的抵持力，以消除偏移的影响，使得齿条40的移动方向保持稳定，从而保证抽屉100拉出或推进过程不偏移。
具体的，结合如图8至图10，所述调节组件52包括壳体53、位于所述壳体53内的罩体54及顶簧55。
所述壳体53固设于所述内胆处，所述罩体54套设于所述齿轮51外，所述顶簧55位于所述罩体54及所述壳体53之间。
其中，所述齿轮51可相对所述罩体54原地转动，且于第一方向X上，所述罩体54与所述齿轮51相对静止，所述顶簧55驱动所述罩体54及所述齿轮51一起沿第一方向X运动。
所述罩体54呈“门”字型，所述罩体54包括底壁541及两个凸伸出底壁541的侧壁542，所述底壁541及所述侧壁542围成一空腔以容纳所述齿轮51。
其中，每一所述侧壁542上设有一开口543，所述齿轮51的中部朝侧壁542方向凸伸形成有凸柱511，当所述凸柱511与所述开口543相互配合时，所述齿轮51可相对所述罩体54原地转动。
也就是说，齿轮51可以相对罩体54转动，但齿轮51不会相对罩体54沿第一方向X或其他方向移动，如此，可以通过罩体54带动齿轮51沿第一方向X移动，且在移动过程中，齿轮51可以始终保持转动状态。
所述壳体53上形成有与所述凸柱511配合的槽道534，槽道534沿第一方向A延伸，当所述齿轮51移动时，所述凸柱511于所述槽道532内移动，所述槽道534限制齿轮51的移动方向。
所述壳体53包括相互配合的前壳体531及后壳体532，所述后壳体532陷于所述内胆内，所述前壳体531位于所述内胆靠近所述抽屉100的一侧。
这里，后壳体532为半封闭壳体，后壳体532整个陷在内胆内，前壳体531与后壳体532相互配合，所述前壳体531为类似平板状结构，平板状结构处凸伸出卡爪(未标示)而与后壳体532相互卡和。如此，可以方便安装拆卸。
前壳体531朝向后壳体532方向凸伸形成有边缘部533，所述边缘部533位于所述后壳体532内部且位于罩体54的外侧，所述边缘部533上形成有所述槽道534，所述齿轮51的凸柱511穿过罩体54上的开口543而限位于所述槽道534内。
另外，所述前壳体531上形成有一贯穿孔535，所述齿轮51穿过所述贯穿孔535而齿合于所述齿条40上。这里，贯穿孔535可由上述边缘部534围成。
进一步地，在本实施方式中，所述底壁541靠近所述后壳体532的一侧沿第一方向X凸伸形成有柱体544，所述顶簧55套设于所述柱体544上，且所述顶簧55的两端分别对应所述底壁541及所述壳体53，其中，所述柱体544及所述顶簧55可相对所述后壳体532运动以驱动所述罩体54及所述齿轮51一起沿第一方向X运动。
后壳体532朝向柱体544凸伸形成有空心柱体536，所述柱体544及顶簧55限位于空心柱体536内，以控制柱体544及顶簧55的运动方向。
较佳地，所述柱体544为圆柱体，所述空心柱体536的内腔呈圆柱状，且空心柱体536的内径大于柱体544的外径。
可以理解，柱体544及空心柱体536的设置可以有效控制顶簧55的形变方向，从而保证齿轮51对齿条40的作用力始终保持在第一方向X。
这里，当顶簧55处于未压缩状态时，柱体544与后壳体532之间具有一定间距；当顶簧55处于压缩状态时，柱体544逐渐靠近后壳体532运动；当柱体544抵持后壳体532时，顶簧55达到最大压缩量。
下面，介绍抽屉100于箱体200内的拉出推进过程。
当将抽屉100推进箱体200时，先将抽屉100倾斜一定角度***箱体200，使得滑条20进入滑槽30内，且齿条40的斜面41相对齿轮51滑动。
左右调整抽屉100位置，使得左右两侧的滑条20的对位部21同时接触对应的下限位部31，此时，左右两侧齿条40的第一齿42均与对应的齿轮51齿合。
继续推动抽屉100，对位部21越过下限位部31而继续向推进方向移动，齿条40在齿轮51沿第一方向X的作用力的作用下继续向推进方向移动，此时抽屉100可以无偏移地向推进方向移动，直至抽屉100到达极限位置。
当将抽屉100拉出箱体200时，齿条20在齿轮51沿第一方向X的作用力的作用下向拉出方向移动，此时抽屉100可以无偏移地向拉出方向移动。
当拉出过程产生顿挫感时，用户需要将抽屉100抬起，使得抽屉100上的凸部脱离上限位部，并将抽屉100抽离箱体200。
