具体实施方式
为了使本技术领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
首先定义抽屉朝向用户移动的方向为前侧，向箱体内移动的方向为后侧，请参图1至图10所示为本发明冰箱的实施例，所述冰箱包括箱体1、设置于所述箱体1内的抽屉2，其中，所述冰箱还包括设置于箱体1和抽屉2之间的自锁机构，所述自锁机构包括设置于箱体侧壁上心形槽3、与心形槽3相配合的滑动机构4、弹性件5，所述滑动机构4设有滑动设置于所述心形槽3内的滑动结构和与所述抽屉2相配合的配合结构，所述弹性件5具有在抽屉2闭合状态时使抽屉2向前移动的弹性势能。
具体地，如图1至图3所示，在本实施例中，所述自锁机构还包括 位于所述心形槽3前侧且与之相连通的滑槽31、位于心形槽3中间的心形块32，即所述心形槽3是围绕所述心形块32所形成的槽道，故该槽道的外形类似于心形。此外，所述心形槽3具有分别位于心形块32上下两侧供滑动机构4移动的退出槽33和锁定槽34、位于心形块32后侧且上下间隔设置的退出导向部35和锁定导向部36。
所述退出槽33位于所述心形块32的上方，所述锁定槽34位于所述心形块32的下方，当所述抽屉2需要闭合时，所述滑动机构4沿所述滑槽31移动至所述心形槽3内时，先向下移动并沿锁定导向部36向上移动，然后在所述弹性件5与抽屉2的作用下定位于所述心形块32，当所述抽屉2需要打开时，所述滑动机构4沿所述退出导向部35移动并在所述弹性件5的作用下，使所述滑动机构4沿所述退出槽33移动至所述滑槽31内，从而打开抽屉2。
当然在其他实施例中，所述退出槽33和所述锁定槽34的位置可以互换，所述退出导向块和所述锁定导向块的位置也可以互换。
在本实施例中，所述滑槽31、所述心形槽3与箱体侧壁一体成型而成，如此，不仅工艺简单，且生产效率极高，而且，所述滑槽31和所述心形槽3均为自箱体侧壁凹陷形成，因此，最大程度减小了自锁机构所占横向方向上的宽度，从而减小了抽屉侧壁和箱体侧壁之间的距离，进而提升抽屉2容量。
当然在其他实施例中，所述滑槽31、所述心形槽3及所述心形块32也可以设置一元件上，然后将该元件组装至箱体侧壁上，如此，当出现损坏时，可方便拆卸维修更换。
所述滑动机构具有滑块41和旋转性地固定于所述滑块41上的定位杆42，所述配合结构设置于所述滑块41上，所述滑动结构设置于所述定位杆42上，所述箱体设有用以定位所述滑块的定位结构。通过将滑块41和定位杆42作为一个组件先固定至箱体上，抽屉安装时与滑块41对接配合即可。
如图4至图7所示，在本实施例中，抽屉2具有其侧壁突伸以驱动所述滑块41前后移动的凸块43。通过凸块43与滑块41的配合设计，可提高凸块43与滑块41的作用面积，即无论是打开抽屉2还是关闭抽屉2时，作用面积越大，则所述凸块43可承受的力则越大，或者说所述凸块43所承受的压强越小，在长期使用过程中，所述凸块43不易受损。
当然在其他实施例中，所述滑动机构4也可为仅为所述定位杆42，所述定位杆42的后端和所述滑槽31、所述心形槽3和所述心形块32相配合，所述定位杆42的前端枢接于抽屉侧壁，如此，结构较为简单。
所述定位杆42沿前后方向呈弧形设计，当抽屉需要打开时，滑块41推动定位杆42的力的方向是斜向上的，从而更好使定位杆42退出，所述定位杆42的前后两端分别具有沿横向方向突伸的第一轴和第二轴，所述第一轴和所述第二轴的突伸方向不同，所述第一轴用以与所述心形块32配合实现固定，所述第二轴用以与所述滑块41枢接。
所述定位杆42呈中心对称设置，当组装所述定位杆42至所述滑块41时，无需检查是第一轴还是第二轴，直接安装即可，大大提高组装效率。
所述滑块41具有基部411、自所述基部411向下延伸的固定部412、连接所述固定部和基部的三角形结构，该三角形结构可提高滑块41的结构强度，所述第二轴枢接于所述基部411的后端，所述基部411的前端具有沿横向方向延伸以沿所述滑槽31移动的滑动部413。所述基部411还具有沿上下方向凹陷以和所述凸块43相配合的凹槽414，所述抽屉2通过所述凸块43来控制所述滑块41前后移动，进而控制所述定位杆42前后移动。所述固定部412具有沿横向方向凹陷设置的限位槽415。
在本实施例中，所述滑动结构即上述第一轴，所述配合结构即上述凹槽414。当然在其他实施例中，所述滑动机构4仅为所述定位杆42时，则所述滑动结构即上述第一轴，所述配合结构即上述第二轴。
所述冰箱还具有自箱体侧壁突伸的连接部11，在本实施例中，所述 连接部11位于所述滑槽31的前端，所述弹性件5的前后两端分别连接所述连接部11和所述固定部412。当所述抽屉2向后移动时，所述滑块41拉动所述弹性件5向后移动，当所述抽屉2闭合时，所述弹性件5呈拉伸状态，因此，所述弹性件5具有使所述抽屉2向后移动的弹性势能。
如此，通过将所述弹性件5设置于所述滑块41上，将所述滑块41横向方向的宽度来收容所述弹性件5，不仅集成度高，而且还无需在箱体1内单独为所述弹性件5设置安装区域，提升了所述抽屉2的容量，再者，当抽屉2取出时，所述滑块41连接弹性件5，也不易活动。
当然在其他实施例中，所述弹性件5的后端也可直接连接于所述基部411的前端，亦或者将所述连接部11设置于所述心形槽3的后端，然后，所述弹性件5的前后分别连接所述固定部412和所述连接部11，那么，当所述抽屉2向后移动时，所述滑块41压缩所述弹性件5向后移动，当所述抽屉2闭合时，所述弹性件5呈压缩状态，因此，所述弹性件5同样具有使所述抽屉2向后移动的弹性势能。
所述定位结构还包括设置箱体侧壁一侧且沿前后方向延伸的限位件12，所述滑块41滑动设置于限位件12和箱体侧壁之间，在本实施例中，所述限位件12连接于所述连接部11，且所述连接部11位于所述限位件12的最前端。所述冰箱还具有自箱体侧壁沿横向方向延伸以连接所述限位件12后侧的加强部，如此，通过所述加强部和所述连接部11可有效提高所述限位件12的结构强度。而且所述弹性件5位于箱体侧壁和所述限位件12之间，实现隐藏式设计，用户不易直接观察到。
在本实施例中，所述限位件12具有和所述滑槽31平行设置的开槽121，因此，可保证所述滑块41可稳定地沿所述滑槽31和所述开槽121移动，所述滑槽31和所述开槽121的前端均设有向下凹陷以收容所述滑动部413的凹陷部311。当然在其他实施例中，所述限位件12还可以具有沿横向方向延伸的支撑部、自所述支撑部向上沿延伸的限位壁，所述限位壁和箱体侧壁共同限位所述滑块41移动。
当打开抽屉2时，所述凸块43带动所述滑块41向前移动，当所述滑动部413移动至所述凹陷部311时，所述滑动部413进入所述凹陷部311，因此，所述滑块41的前端则向下倾斜并使所述凸块43退出所述凹槽414，从而实现将抽屉2取出。
如图5所示，在本实施例中，所述凹槽414具有供凸块43驱动滑块41向前移动的前内壁4141、供凸块43驱动滑块41向后移动的后内壁4142，所述凹槽414的前内壁4141低于所述凹槽414的后内壁4142。
如此，当所述滑动部413滑动至所述凹陷部311时，所述凹陷部311只需向下凹陷较短的距离，因此，所述滑动部413也只需下降较低的高度，使得所述滑动部413只需部分位于所述凹陷部311内，即可实现取出所述抽屉2。
当再次将抽屉2安装并闭合于箱体1时，由于所述滑动部413仅部分位于所述凹陷部311，那么向后推动抽屉2时，容易使所述凸块43带动所述滑块41的滑动部413离开所述凹陷部311，从而提高安装抽屉2的效率。
为进一步提高所述滑动部413滑出所述凹陷部311从而进入所述滑槽31的流畅度，所述凹陷部311的后端还可设置一过渡段，所述过渡段呈自后向前逐渐下降的趋势。
所述滑块41在凹槽414的前侧设有自后向前逐渐向下倾斜延伸的斜面，当所述滑块41前端进入所述凹陷部311时，所述凹槽414的前侧不会阻碍所述滑动部413进入所述凹陷部311，即假设凹槽414的前侧为矩形结构，当滑动部413进入所述凹陷部311时，该矩形结构的顶角会抵接凹陷部311的内壁从而阻止下移。
如图8所示，所述自锁机构还包括自箱体侧壁朝所述限位件12突伸的限位板13，所述限位板13的延伸方向与所述限位件12的延伸方向相同，且所述限位板13与所述限位件12沿横向方向间隔设置，所述固定部412的限位槽415与所述限位板13相配合以使所述固定部412沿所述 限位板13前后滑动，从而避免了所述滑块41在移动过程中沿所述滑动部413上下移动。在本实施例中，所述限位板13位于所述滑槽31下方。当然也可位于所述滑槽31上方。
所述限位板13与所述连接部11之间间隔设置，当安装所述滑块41和定位42时，只需将定位杆42第一轴安装至滑槽31内，再将滑块41的限位槽415对准限位板13并借由限位板13与连接部11之间的间隙即可向后安装至滑槽31和开槽121内。另一种方法为将心形块32设置为可拆卸的结构，组装滑块41和定位杆42时，先拆卸心形块32，再将一侧的滑动部413对准滑槽31，另一侧的滑动部413安装至开槽121内，再将心形块32组装即可。
在本实施例中，所述冰箱还具有设置箱体1后侧壁上以在抽屉2打开时推动抽屉2后侧壁的辅助推弹机构6。当抽屉2处于闭合时，向后推动所述抽屉2，所述辅助推弹机构6向后压缩从而给到抽屉2向前的推力，从而与所述弹性件5相互配合增加抽屉2的退出速度，从而提高抽屉2退出解锁的流畅度。
当然在其他实施例中，也可不设置所述辅助推弹机构6。亦或者仅设置所述辅助推弹机构6，而无需设置所述弹性件5，只需要在抽屉2闭合时，向后推动抽屉2所述辅助推弹机构6具有使抽屉2向前移动的弹性势能即可，如此只需向后推动抽屉2，抽屉2在弹力的作用下向前移动从而实现解锁退出。
所述冰箱还具有设置于箱体侧壁和抽屉侧壁之间的移动机构，在本实施例中，所述移动机构包括设置于所述箱体侧壁且沿前后方向间隔设置的多个滚轮7，设置于抽屉侧壁和所述滚轮7配合滑动的滑道21。
如图9和图10所示，所述抽屉2的具体工作过程为：
当需要打开抽屉2时，先向后推动抽屉2，所述定位杆42沿退出导向部35向上移动，并在所述弹性件5的拉力作用下迅速沿所述退出槽33滑动至所述滑槽31，从而实现解锁。
当需要将所述抽屉2取出箱体1时，只需一直向前拉动抽屉2即可，当所述滑块41的滑动部413移动至所述凹陷部311时，所述滑动部413向下进入凹陷部311，所述凹槽414的前端下降，接触所述凸块43与所述凹槽414的配合，直接拉出抽屉2即可，即在整个抽屉2的取出过程，先向后推动抽屉2再一直向前拉出即可。
当需要闭合抽屉2时，将抽屉2两侧的滑道21对准滚轮7向后推动，直至所述凸块43与所述凹槽414的后内壁4142相接触，进一步向后推动抽屉2，所述滑动部413退出所述凹陷部311，直至所述定位杆42沿滑槽31进入锁定槽34，再经由锁定导向部36向上移动，最终受弹性件5作用向前移动定位于心形块32。
综上所述，本发明的冰箱本发明的冰箱通过将心形槽3设置于箱体侧壁上。不仅结构简单，还可避免使用滑轨，从而减小箱体侧壁和抽屉侧壁之间的间隙，进而增加抽屉2的容量。
