- the left and right sway is generated during the use process: the existing three-section slide rail adopts the paired mode in the practical application, and adopts the operation mode described above, and the transmission between the three sections of the slide rail adopts a plurality of steel balls as the inter-rail slide device. Therefore, the three sections of slide rails cannot be locked with each other, and the space for expansion and contraction is reserved in front and rear.

Description
本申请要求了申请日为2016年05月25日,申请号为201610355667.2,发明名称为“滑轨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。
本发明涉及家电领域,尤其涉及一种滑轨机构及具有其的冰箱。
目前,市场上的三节滑轨在实际应用中主要存在如下问题:首先,使用过程中产生噪音:现有的三节滑轨,采用上轨先运行,当上轨运行距离达到极点时,采用上轨与中轨的限位装置接触碰撞,将中轨拉出;同样采用中轨与下轨的限位装置接触碰撞,达到中轨被牵引的距离到达极点;而限位装置在上轨与中轨、中轨与下轨接触撞击中产生“蹬、蹬”的噪音,给用户带来高频噪音。其次,使用过程中产生左右晃动:现有的三节滑轨在实际应用中多采用成对的方式,并采用上述描述的运行方式,同时三节滑轨间的传动采用若干钢珠作为各轨间滑动装置;因此,三节滑轨相互间不能锁住,前后预留升缩空间,在实际使用中,拉出时的作用力和滑轨运行力的方向不在滑轨的中心线上,导致通过一对三节滑轨拉出的装置面会出现一前一后的情景,并在拉出后任意位置,当双手使用两边作用力大小不一样时,会产生左右摇晃的现象,给用户带来安全隐患。
市场上现有的三节滑轨受成本、标准工艺控制及可靠性的影响,上轨与下轨之间的缝隙距离一般在2mm。现有技术中,如本司申请号为CN201410372586.4的发明专利申请为例,可在三节滑轨中增加同步机构以实现两侧滑轨的同步进出,该同步机构的转向件包括基座,基座必须安装在中轨上整个同步机构才能达到预期的同步静音效果,也就是说,基座需安装在2mm的缝隙内。另外,为了保证基座的强度,基座与中轨连接的连接部的尺寸不宜做的太小,较佳设置成1.8mm的高度,如此一来,上轨与连接部之间的间距大致为0.1mm,下轨与连接部之间的间距也大致为0.1mm。实际运用中,随着三节滑轨使用次数的增加,内部的钢珠及上轨、下轨、中轨容易产生磨损,导致上轨与下轨之间的缝隙距离逐渐减小,由于上轨及下轨与基座连接部之间的间距极小,此时,缝隙距离的减小容易导致上轨和/或下轨与基座连接部之间产生干涉,甚至产生卡死现象。因此,现有技术中的三节滑轨可靠性存在问题。

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所示,本发明提供了一种用于抽屉(未标示)在箱体内拉出或推进的滑轨机构100,包括相对设置的两组滑轨组件1。当然,所述滑轨机构100也可以用于其他结构的抽拉、扩展或收缩。需要说明的是,两组滑轨组件1可以左右设置,在其他实施例中,两组滑轨组件1也可以上下设置,在本发明中,以两组滑轨组件1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。
参图1至图3,所述滑轨组件1包括第一滑轨组件1a和第二滑轨组件1b,每一滑轨组件1具有相互滑动配合的上轨11、中轨12和下轨13,即第一滑轨组件1a具有相互配合的第一上轨11a、第一中轨12a和第一下轨13a,所述第二滑轨组件1b具有相互配合的第二上轨11b、第二中轨12b和第二下轨13b。所述下轨13通过角铁6固定于箱体上,所述上轨11固定于抽屉上,所述中轨12配合设置于所述上轨11与下轨13之间;使用时,所述下轨13固定不动,所述中轨12和上轨11可相对下轨13拉出或推进,进而带动抽屉拉出或推进所述箱体内,也就是说,所述下轨13为定轨,所述中轨12和上轨11为动轨。
在本实施方式中,所述滑轨组件1还包括设于所述上轨11与所述中轨12之间的上联排滚珠14、设于所述中轨12与所述下轨13之间的下联排滚珠15,在上轨11或中轨12相对下轨13拉出或推进的过程中可以减小摩擦,省力。所述上联排滚珠14位于所述上轨11的开口(未标示)内,所述下联排滚珠15位于所述下轨13的开口(未标示)内。进一步地,所述上联排滚珠14包括卡固于中轨12上侧的基体(未标示)及设于基体上的若干滚珠(未标示),所述下联排滚珠15包括卡固于中轨12下侧的基体(未标示)及设于基体上的若干滚珠(未标示)。
在本发明一实施方式中,所述滑轨机构100还包括使得第一滑轨组件1a和第二滑轨组件1b保持同步移动的同步机构2,同步机构2包括与两组滑轨组件1配合的两组辅助中轨组件5、设于所述辅助中轨组件5的转向件21、张紧件23以及设于两组滑轨组件的固定件22,所述张紧件23通过转向件21绕置于两个滑轨组件1的固定件22之间,使得第一滑轨组件1a的上轨11或中轨12移动时,所述张紧件23通过固定件22带动第二滑轨组件1b的上轨11或中轨12同向位移相同距离。
这里,在现有技术三节滑轨的基础上,增加了辅助中轨组件5,且将同步机构2的转向件21设置于辅助中轨组件5上,转向件21与三节滑轨之间彼此不接触,也就是说,此时转向件21、张紧件23的移动轨迹与三节滑轨的滑动轨迹彼此不重叠,即使上轨11、下轨13之间的缝隙因磨损而减小,也不会影响到同步机构2中转向件21的正常运作,可以有效解决现有技术中转向件21与上轨11和/或下轨13干涉的问题。另外,本实施方式可以利用市场上常见的三节滑轨结构,仅需配合成本低廉的辅助中轨组件即可,从而不仅可以简化制作难度,还可以大大降低生产成本。
在本实施方式中,一并参阅图4及图5,每一所述辅助中轨组件5包括至少一限位座51及至少一丝杆52,所述丝杆52可活动地设置于所述限位座51内,所述丝杆52连接所述转向件21,当所述上轨11或中轨12移动时,所述限位座51保持不动,所述丝杆52及所述转向件21共同相对所述限位座51同向移动。这里,所述转向件21包括基座213(213’)及设置于基座213内的轮盘(未标示),所述张紧件23绕设于所述轮盘处,所述丝杆52与所述基座213(213’)相互固定,丝杆52与基座213(213’)之间可通过插销53和/或螺栓件54相互固定,转向件21、丝杆52与三节滑轨之间不接触。需要说明的是,本实施方式的丝杆52具有一定的强度,其不易变形,通过丝杆52连接转向件21,可以有效导引转向件21的运动,另外,通过限位座51对丝杆52的限位,可以有效控制丝杆52的移动方向,使得丝杆52的移动方向与所述上轨11和/或中轨12的移动方向保持一致,也就是说,丝杆52的中轴线与张紧件23平行且处于同一竖直平面内。
在本实施方式中,限位座51可固设于下轨13上,但不以此为限,例如,可提供一支撑板55,并将限位座51固设于支撑板55上,支撑板55可与下轨13或箱体或角铁6连接,在一实施例中,支撑板55可与固定下轨13的角铁6一体成型。为了进一步有效控制丝杆52的移动方向,还可在支撑板55、下轨13或限位座51上设计一限位槽56,如图5所示,在支撑板55的上表面上形成一水平延伸的限位槽56,限位槽56与丝杆52彼此配合,当所述丝杆52移动时,所述限位槽56限制所述丝杆52的移动方向。所述限位座51包括相互分隔设置的第一***端511及第二***端512,所述丝杆52限位于所述第一***端511及所述第二***端512内,这里,设置相互分隔的两端,可有效提高限位座51对丝杆52的限位效果,同时,也可保证丝杆52移动的顺畅性。
在本实施方式中,所述转向件21包括前转向件211及后转向件212,所述前转向件211位于所述丝杆52的前端,所述后转向件212位于所述丝杆52的后端,所述限位座51位于所述前转向件211及所述后转向件212的中间区域。这里,当一个辅助中轨组件5仅有一根丝杆52时,前转向件211及后转向件212分别位于同一根丝杆52的前端及后端,丝杆52带动前转向件211及后转向件212一起移动;
当一个辅助中轨组件5具有大于一根的丝杆52时,例如辅助中轨组件5具有两根丝杆52时,前转向件211位于其中之一丝杆52的前端,后转向件212位于其中另一丝杆52的后端。需要说明的是,所述限位座51位于所述前转向件211及所述后转向件212的中间区域,限位座51位于后转向件212的运动路径上,为了保证后转向件212可以顺畅地朝前移动,限位座51较佳靠近三节滑轨前端区域设置。
在本实施方式中,所述前转向件211包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一前转向件211a及第二前转向件211b,所述后转向件212包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一后转向件212a及第二后转向件212b。
结合图6,所述前转向件211被设置为所述张紧件23经过前转向件211后被分成上层张紧件231与下层张紧件232,所述后转向件212包括分别与所述上层张紧件231与下层张紧件232相配合的上转向件2121与下转向件2122,所述上层张紧件231、下层张紧件232经过其中一滑轨组件1的上转向件2121、下转向件2122后分别延伸向固定于另一滑轨组件1上的下转向件2122与上转向件2121,以交叉联动的方式分别位于两组滑轨组件1的上轨11与下轨13。
所述前转向件211为供张紧件23绕过的轮盘(未标示),其呈竖向安装,所述上转向件2121与下转向件2122为供张紧件23绕过的轮盘(未标示),其呈水平安装,所述张紧件23于所述前转向件211的最高位置与所述张紧件23于所述上转向件2121的位置位于同一直线上,使得所述上层张紧件231平行于所述丝杆52;所述张紧件23位于所述前转向件211的最低位置与位于所述下转向件2122的位置位于平行于丝杆52的一条直线上,以使得所述下层张紧件232平行于所述丝杆52;从而使得所述滑轨机构100运行顺畅。
所述固定件22包括分别设于两个上轨11上的至少两个上固定件221及设于至少一个下轨13上的至少一个下固定件222。
在所述滑轨组件1打开、关闭及打开或关闭的过程中,所述上固定件221始终位于所述上轨11后端到中轨12前端之间,所述下固定件222始终位于所述下轨13前端到中轨12后端之间,以避免三节滑轨相互脱离、减少张紧件23在转向件21及固定件22处的磨损,延长使用寿命,同时不影响所述滑轨机构100可将抽屉拉出箱体的有效长度。
在滑轨组件1完全打开时,所述上轨11的后部与所述中轨12的前部有部分重叠,同时所述中轨12的后部与所述下轨13的前部有部分重叠,以增强滑轨组件1在打开状态时的文稳定性,防止抽屉晃动。优选地,所述上固定件221距上轨11后端的距离为所述上轨11与中轨12完全打开时所述上轨11后端到中轨12前端的距离的一半;所述下固定件222距下轨13前端的距离为所述下轨13与中轨12完全打开时所述下轨13后端到中轨12前端的距离的一半,不影响所述滑轨机构100可将抽屉拉出箱体的有效长度,且可以避免所述转向件21与固定件22发生碰撞或摩擦,延长使用寿命。在滑轨组件1完全打开时,假设上轨11后端到中轨12前端的距离为L,则上固定件221距离上轨11后端的距离为L/2;中轨12后端到下轨13前端的距离为M,则下固定件222距离下轨13前端的距离为M/2。
所述张紧件23通过前转向件211和后转向件212绕置于两个滑轨组件1的固定件22之间并形成回路,即所述张紧件23通过前转向件211和后转向件212变换方向从而连接所述上固定件221与下固定件222。本发明中,形成回路是指:所述张紧件23位于同一固定件22前侧和后侧的两部分通过该固定件22紧密连接,无断点;所述张紧件23位于同一固定件22前侧和后侧的两部分固定于同一滑轨上,两个固定点之间无转向件21。当然,在本发明具体实施方式中,也可根据具体情况不形成回路。
在本发明一具体示例中,参阅图6,所述固定件22包括设于第一滑轨组件1a上的第一上固定件221a及第一下固定件222a、设于第二滑轨组件1b上的第二上固定件221b,所述张紧件23通过三个固定件22分为三段:经过第一前转向件211a并连接第一下固定件222a与第一上固定件221a的第一张紧件,依次经过第一后转向件212a、第二后转向件212b及第二前转向件211b并连接第一上固定件221a与第二上固定件221b的第二张紧件,依次经过第二后转向件212b和第一后转向件212a并连接第二上固定件221b与第一下固定件222a的第三张紧件。所述第一张紧件、第二张紧件和第三张紧件彼此通过固定件22相连接,形成一个闭合的回路。
在抽拉抽屉时,当第一上轨11a受力向外拉出距离a时,第一滑轨组件1a的上层张紧件231通过第一前转向件211a和第一后转向件212a向下层张紧件232传动距离a,而张紧件23在第一前转向件211a和第二后转向件212b之间的距离是固定的,因此所述第二滑轨组件1b的下层张紧件232通过第二前转向件211b、第二后转向件212b及第一后转向件212a向第一滑轨组件1a的上层张紧件231传动距离a;
又因为第二前转向件211b与第二后转向件212b之间的距离是固定的,因此第二滑轨组件1b的上层张紧件231向下层张紧件232传动距离a,同时第一滑轨组件1a的下层张紧件232通过第一前转向件211a、第一后转向件212a和第二前转向件211b、第二后转向件212b向第二滑轨组件1b的上层张紧件231传动距离a。
第一滑轨组件1a的上层张紧件231分别通过第一上固定件221a、第一下固定件222a固定于第一上轨11a、第一下轨13a上;第二滑轨组件1b的上层张紧件231通过第二上固定件221b固定于第二上轨11b上。同时第一张紧件、第二紧件和第三张紧件的长度都是固定的。在抽拉抽屉时,当第一滑轨组件1a的上轨11受力向外拉出距离a时,第一滑轨组件1a的上层张紧件231向下层张紧件232传动距离a,第二滑轨组件1b的下层张紧件232向第一滑轨组件1a的上层张紧件231传动距离a,第二滑轨组件1b的上层张紧件231向第二滑轨组件1b的下层张紧件232传动距离a,因此第二上轨11b也向外拉出距离a。同时,第一滑轨组件1a的下层张紧件232向第二滑轨组件1b的上层张紧件231传动距离a,由于第三张紧件的长度是固定的,因此第二后转向件212b向前拉出。
当第二滑轨组件1b的上轨11受力向外拉出距离a时,所述第三张紧件的长度是固定的,第三张紧件通过第二后转向件212b与第一后转向件212a向第二滑轨组件1b的上轨11传动距离a,因此第一滑轨组件1a的第一后转向件212a向前拉出;又因为所述第一张紧件的长度是固定的,故第一滑轨组件1a的上轨11也向外拉出距离a。另外,由于上轨11与中轨12之间为滑动连接,中轨12与下轨13之间也为滑动连接,上轨11的移动会带动中轨12一起移动,以增加可拉出距离。
在本发明另一具体示例中,参阅图7,与上一具体示例相同的部件采用相同的标号,所述固定件22包括设于第一滑轨组件1a上的第一上固定件221a及第一下固定件222a、设于第二滑轨组件1b上的第二上固定件221b及第二下固定件222b。
所述张紧件23包括经过第一前转向件211a并连接第一下固定件222a与第一上固定件221a的第一张紧件,依次经过第一后转向件212a、第二后转向件212b并连接第一上固定件221a与第二下固定件222b的第二张紧件,经过第二前转向件212a并连接于第二下固定件222b及第二上固定件221b的第三张紧件、依次经过第二后转向件212b和第一后转向件212a并连接第二上固定件221b与第一下固定件222a的第四张紧件。所述第一张紧件、第二张紧件、第三张紧件及第四张紧件彼此通过固定件22相连接,形成一个闭合的回路。本示例的其他说明可参考上一示例,在此不再赘述。
下面,介绍本发明辅助中轨组件5的几种具体实施方式,相同的结构采用相同的编号。
如图1-7所示,在本发明第一实施方式中,所述滑轨机构100包括使得第一滑轨组件1a和第二滑轨组件1b保持同步移动的同步机构2,同步机构2包括与两组滑轨组件1配合的两组辅助中轨组件5a、设于所述辅助中轨组件5a的转向件21、张紧件23以及设于两组滑轨组件的固定件22,每一所述辅助中轨组件5a位于对应的所述滑轨组件1靠近抽屉容置空间的一侧,所述张紧件23通过转向件21绕置于两个滑轨组件1的固定件22之间,使得第一滑轨组件1a的上轨11或中轨12移动时,所述张紧件23通过固定件22带动第二滑轨组件1b的上轨11或中轨12同向位移相同距离。也就是说,在本实施方式中,辅助中轨组件5a位于滑轨组件1的内侧。
这里,在现有技术三节滑轨的基础上,增加了辅助中轨组件5a,且将同步机构2的转向件21设置于辅助中轨组件5a上,转向件21与三节滑轨之间彼此不接触,也就是说,此时转向件21、张紧件23的移动轨迹与三节滑轨的滑动轨迹彼此不重叠,即使上轨11、下轨13之间的缝隙因磨损而减小,也不会影响到同步机构2中转向件21的正常运作,可以有效解决现有技术中转向件21与上轨11和/或下轨13干涉的问题。另外,本实施方式可以利用市场上常见的三节滑轨结构,仅需配合成本低廉的辅助中轨组件即可,从而不仅可以简化制作难度,还可以大大降低生产成本。
每一辅助中轨组件5a包括一个限位座51a及一根丝杆52a,所述丝杆52a可活动地设置于所述限位座51a内,所述丝杆52a连接所述转向件21,当所述上轨11或中轨12移动时,所述限位座51a保持不动,所述丝杆52a及所述转向件21共同相对所述限位座51a同向移动。这里,限位座51a呈“凹”状,限位座51a的底面与支撑板55a之间通过螺丝(未标示)固定,限位座51a还包括凸伸出底面的第一***端511a及第二***端512a,第一***端511a及第二***端512a的开口朝水平方向延伸,丝杆52a限位于所述第一***端511a及所述第二***端512a内。支撑板55a为水平设置的硬质板,支撑板55a与角铁6或下轨11之间可通过螺丝所述,当然,支撑板55a也可和角铁6或下轨11一体成型。本实施方式通过限位座51a的设置可以有效控制丝杆52a的移动方向,使得丝杆52a的移动方向与所述上轨11
和/或中轨12的移动方向保持一致,也就是说,丝杆52a的中轴线与张紧件23平行且处于同一竖直平面内。
在本实施方式中,支撑板55a的上表面还形成有一限位槽56a,其与丝杆52a对应设置,以增强对丝杆52a的移动方向的控制。
在本实施方式中,前转向件211位于丝杆52a的前端,后转向件212位于丝杆52a的后端,所述前转向件211包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一前转向件211a及第二前转向件211b,所述后转向件212包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一后转向件212a及第二后转向件212b。所述固定件22位于所述滑轨组件1靠近抽屉容置空间的一侧,即固定件22位于滑轨组件1的内侧,固定件22包括设于第一滑轨组件1a上的第一上固定件221a及第一下固定件222a、设于第二滑轨组件1b上的第二上固定件221b,所述张紧件23通过三个固定件22分为三段:经过第一前转向件211a并连接第一下固定件222a与第一上固定件221a的第一张紧件,依次经过第一后转向件212a、第二后转向件212b及第二前转向件211b并连接第一上固定件221a与第二上固定件221b的第二张紧件,依次经过第二后转向件212b和第一后转向件212a并连接第二上固定件221b与第一下固定件222a的第三张紧件。所述第一张紧件、第二张紧件和第三张紧件彼此通过固定件22相连接,形成一个闭合的回路。当然,所述固定件22也可包括设于第一滑轨组件1a上的第一上固定件221a及第一下固定件222a、设于第二滑轨组件1b上的第二上固定件221b及第二下固定件222b,此时,张紧件23包括第一张紧件、第二张紧件、第三张紧件及第四张紧件。本实施方式的其他说明可以参考本说明书其他部分的说明,在此不再赘述。
如图8-12所示,在本发明第二实施方式中,所述滑轨机构100还包括使得第一滑轨组件1a和第二滑轨组件1b保持同步移动的同步机构2,同步机构2包括与两组滑轨组件1配合的两组辅助中轨组件5b、设于所述辅助中轨组件5b的转向件21、张紧件23以及设于两组滑轨组件的固定件22,每一所述辅助中轨组件5b包括分别位于对应的所述滑轨组件1靠近及远离抽屉容置空间两侧的两个辅助中轨,所述张紧件23通过转向件21绕置于两个滑轨组件1的固定件22之间,使得第一滑轨组件1a的上轨11或中轨12移动时,所述张紧件23通过固定件22带动第二滑轨组件1b的上轨11或中轨12同向位移相同距离。也就是说,在本实施方式中,每一辅助中轨组件5b位于对应的滑轨组件1的内外侧。
这里,在现有技术三节滑轨的基础上,增加了辅助中轨组件5b,且将同步机构2的转向件21设置于辅助中轨组件5b上,转向件21与三节滑轨之间彼此不接触,也就是说,此时转向件21、张紧件23的移动轨迹与三节滑轨的滑动轨迹彼此不重叠,即使上轨11、下轨13之间的缝隙因磨损而减小,也不会影响到同步机构2中转向件21的正常运作,可以有效解决现有技术中转向件21与上轨11和/或下轨13干涉的问题。另外,本实施方式可以利用市场上常见的三节滑轨结构,仅需配合成本低廉的辅助中轨组件即可,从而不仅可以简化制作难度,还可以大大降低生产成本。需要说明的是,相较于第一实施方式,本实施方式将每一辅助中轨组件5b拆分成位于对应的滑轨组件1内侧及外侧的两个辅助中轨,将一部分转向件21及张紧件23转移至滑轨组件1及箱体内胆的中间区域内,可以有效减小辅助中轨组件5b占用的位于滑轨组件1靠近抽屉容置空间一侧的空间,从而可相应增大抽屉体积。
每一辅助中轨包括一个限位座51b(51b’)及一根丝杆52b(52b’),所述丝杆52b可活动地设置于所述限位座51b内,所述丝杆52b连接所述转向件21,当所述上轨11或中轨12移动时,所述限位座51b保持不动,所述丝杆52b及所述转向件21共同相对所述限位座51b同向移动。这里,限位座51b呈“凹”状,两个限位座51b、51b’的底面分别抵接于对应的下轨11靠近及远离抽屉容置空间的两侧表面上。限位座51b还包括凸伸出底面的第一***端511b及第二***端512b,第一***端511b及第二***端512b的开口朝水平方向延伸,丝杆52b限位于所述第一***端511b及所述第二***端512b内。本实施方式通过限位座51b的设置可以有效控制丝杆52b的移动方向,使得丝杆52b的移动方向与所述上轨11和/或中轨12的移动方向保持一致,也就是说,丝杆52b的中轴线与张紧件23平行且处于同一竖直平面内。
在本实施方式中,前转向件211位于丝杆52b’的前端,后转向件212位于丝杆52b的后端,也就是说,此时每一辅助中轨组件5b具有两根丝杆(内侧丝杆52b及外侧丝杆52b’),前转向件211位于外侧丝杆52b’的前端,后转向件212位于内侧丝杆52b的后端。所述前转向件211包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一前转向件211a及第二前转向件211b,所述后转向件212包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一后转向件212a及第二后转向件212b。所述固定件包括分
别位于对应的所述滑轨组件1靠近及远离抽屉容置空间两侧的内侧固定件22及外侧固定件22’,所述内侧固定件22包括设于第一滑轨组件1a上的内侧第一上固定件221a及内侧第一下固定件222a、设于第二滑轨组件1b上的内侧第二上固定件221b及内侧第二下固定件222b;所述外侧固定件22’包括设于第一滑轨组件1a上的外侧第一上固定件221a’及外侧第一下固定件222a’、设于第二滑轨组件1b上的外侧第二上固定件221b’及外侧第二下固定件222b’;所述张紧件23包括经过第一前转向件211a并连接外侧第一下固定件222a’与外侧第一上固定件221a’的第一张紧件,依次经过第一后转向件212a、第二后转向件212b并连接内侧第一下固定件222a与内侧第二上固定件221b的第二张紧件,依次经过第一后转向件212a和第二后转向件212b并连接内侧第一上固定件221a与内侧第二下固定件222b的第三张紧件,经过第二前转向件211b并连接外侧第二下固定件222b’与外侧第二上固定件221b’的第四张紧件。此时,第二张紧件及第三张紧件位于第一滑轨组件1a及第二滑轨组件1b的内侧,第一张紧件及第四张紧件位于第一滑轨组件1a及第二滑轨组件1b的外侧。本实施方式的其他说明可以参考本说明书其他部分的说明,在此不再赘述。
如图13-图17所示,在本发明第三实施方式中,所述滑轨机构100还包括使得第一滑轨组件1a和第二滑轨组件1b保持同步移动的同步机构2,同步机构2包括与两组滑轨组件1配合的两组辅助中轨组件5c、设于所述辅助中轨组件5c的转向件21、张紧件23以及设于两组滑轨组件1的固定件22,每一所述辅助中轨组件5c位于对应的所述滑轨组件1远离上轨11的一侧,所述张紧件23通过转向件21绕置于两个滑轨组件1的固定件22之间,使得第一滑轨组件1a的上轨11或中轨12移动时,所述张紧件23通过固定件22带动第二滑轨组件1b的上轨11或中轨12同向位移相同距离。也就是说,在本实施方式中,辅助中轨组件5c位于滑轨组件1的下侧。需要说明的是,本实施方式的滑轨机构100适用于滑轨机构位于抽屉侧边的情况,此时滑轨组件1的下侧有剩余空间来容纳辅助中轨组件5c,而第一实施方式及第二实施方式的滑轨机构适用于滑轨机构100位于抽屉底部的情况,但并不以此为限。
这里,在现有技术三节滑轨的基础上,增加了辅助中轨组件5c,且将同步机构2的转向件21设置于辅助中轨组件5c上,转向件21与三节滑轨之间彼此不接触,也就是说,此时转向件21、张紧件23的移动轨迹与三节滑轨的滑动轨迹彼此不重叠,即使上轨11、下轨13之间的缝隙因磨损而减小,也不会影响到同步机构2中转向件21的正常运作,可以有效解决现有技术中转向件21与上轨11和/或下轨13干涉的问题。另外,本实施方式可以利用市场上常见的三节滑轨结构,仅需配合成本低廉的辅助中轨组件即可,从而不仅可以简化制作难度,还可以大大降低生产成本。需要说明的是,本实施方式将辅助中轨组件5c设置于滑轨组件1的下方,此时辅助中轨组件5c的设置并不会影响到抽屉的体积。
每一辅助中轨组件5c包括一个限位座51c及一根丝杆52c,所述丝杆52c可活动地设置于所述限位座51c内,所述丝杆52c连接所述转向件21,当所述上轨11或中轨12移动时,所述限位座51c保持不动,所述丝杆52c及所述转向件21共同相对所述限位座51c同向移动。这里,支撑板55c与角铁6一体成型,支撑板55c的上表面与下轨13的下表面接触,限位座51c呈“凹”状,限位座51c的底面抵接于支撑板55c的底部。限位座51c还包括凸伸出底面的第一***端511c及第二***端512c,第一***端511c及第二***端512c的开口朝水平方向延伸,丝杆52c限位于所述第一***端511c及所述第二***端512c内。本实施方式通过限位座51c的设置可以有效控制丝杆52c的移动方向,使得丝杆52c的移动方向与所述上轨11和/或中轨12的移动方向保持一致,也就是说,丝杆52c的中轴线与张紧件23平行且处于同一竖直平面内。
在本实施方式中,前转向件211位于丝杆52c的前端,后转向件212位于丝杆52c的后端,所述前转向件211包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一前转向件211a及第二前转向件211b,所述后转向件212包括分别设于第一滑轨组件1a、第二滑轨组件1b的第一后转向件212a及第二后转向件212b。所述固定件22由上轨11及下轨13(或支撑板55c)延伸至支撑板55c下侧,固定件22包括设于第一滑轨组件1a上的第一上固定件221a及第一下固定件222a、设于第二滑轨组件1b上的第二上固定件221b,所述张紧件23通过三个固定件22分为三段:经过第一前转向件211a并连接第一下固定件222a与第一上固定件221a的第一张紧件,依次经过第一后转向件212a、第二后转向件212b及第二前转向件211b并连接第一上固定件221a与第二上固定件221b的第二张紧件,依次经过第二后转向件212b和第一后转向件212a并连接第二上固定件221b与第一下固定件222a的第三张紧件。所述第一张紧件、第二张紧件和第三张紧件彼此通过固定件22相连接,形成一个闭合的回路。当然,所述固定件22也可包括设于第一滑轨组件1a上的第一上固定件221a及第一下固定件222a、设于第二滑轨组件1b
上的第二上固定件221b及第二下固定件222b,此时,张紧件23包括第一张紧件、第二张紧件、第三张紧件及第四张紧件。本实施方式的其他说明可以参考本说明书其他部分的说明,在此不再赘述。
在本发明一实施方式中,以张紧件23包括第一张紧件、第二张紧件、第三张紧件为例,且以第一实施方式中的滑轨机构100为例,其他实施方式的滑轨机构100也可适用,在此不再一一详述。如图18及图19所示,所述滑轨机构100还包括电机组件3,所述电机组件3具有用以缠绕或释放所述张紧件23的第一连接端31和第二连接端32,所述张紧件23上位于同一固定件22前后两侧的两个部分分别缠绕连接在所述第一连接端31和第二连接端32上,所述电机组件3工作时通过第一连接端31和第二连接端32中一者收缩所述张紧件23、另一者释放所述张紧件23而使得所述张紧件23移动,进而通过固定件22带动所述中轨12和上轨11移动,所述抽屉可在电机的驱动下实现自动抽拉,使用方便。
在本实施方式中,所述上固定件221包括卡固于所述上轨11上的上卡固件2211及与上卡固件相配合的带孔螺母2212,所述上层张紧件231穿于所述带孔螺母2212的孔内被固定。所述下固定件222包括卡固于所述下轨13上的下卡固件2221及设于所述下卡固件2221上第一导向件2222及第二导向件2223,所述下层张紧件232由第一导向件2222及第二导向件2223导向所述电机组件3,以将所述下层张紧件232固定。为了方便理解下固定件222的结构,所述下固定件222的第一导向件2222及第二导向件2223未随所述下卡固件2221移动,仍然与张紧件23固定于一起。带孔螺母2212的孔与所述上转向件2121位于平行于丝杆52的同一直线上,相互配合的第一导向件2222、第二导向件2223、下卡固件2221与所述下转向件2122位于平行于丝杆52的同一直线上,因此所述张紧件23在所述上固定件221与下固定件222固定前后均保持平行于所述丝杆52的同一条直线上。
所述滑轨机构100还包括控制所述电机组件3工作的控制器,当所述控制器接收到拉出或推进所述抽屉的信号时控制所述电机组件3工作。所述电机组件3包括可正反向旋转的电机、由电机驱动并可调整转速的传动齿轮、由传动齿轮带动转动的卷丝筒。所述第一连接端31和第二连接端31均设置于所述卷丝筒上,并且所述张紧件23上位于同一固定件22前后两侧的两个部分分别反向缠绕在所述第一连接端31和第二连接端32上。因此,在所述卷丝筒绕一个方向旋转时,第一连接端31和第二连接端32中一者收缩所述张紧件23、另一者释放所述张紧件23而使得所述张紧件23移动。
所述第一连接端31和第二连接端32分别与第一下固定件222a前后两侧的第一张紧件和第三张紧件相缠绕连接。所述第一下固定件222a具有分别将第一张紧件和第三张紧件导向所述第一连接端31和第二连接端32的第一导向件2222和第二导向件2223。所述滑轨机构100还包括设于第一导向件2222与第一连接端31之间的第一衬套(未标示),所述张紧件23在第一导向件2222与电机组件3之间的部分穿设于所述第一衬套内,所述张紧件23在第一导向件2222与电机组件3之间的长度大于第一导向件2222与电机组件3之间的距离;所述滑轨机构100还包括设于第二导向件2223与第二连接端32之间的第二衬套(未标示),所述张紧件在第二导向件2223与电机组件3之间的部分穿设于所述第二衬套内,且所述张紧件23在在第二导向件2223与电机组件3之间的长度大于第二导向件2223与电机组件3之间的距离。因此,方便所述同步机构2与电机组件3配合安装。
当然,所述第一张紧件、第二张紧件、第三张紧件可以由一根张紧件23、两根张紧件23或三根张紧件23组成。为了简化组装工序,降低成本,本实施例中采用一根张紧件23,所述张紧件23的起始端缠绕连接于第一连接端31,末端依次经过第一导向件2222、第一前转向件211a、第一上固定件221a、第一后转向件212a、第二后转向件212b、第二前转向件211b、第二上固定件221b、第二后转向件212b、第一后转向件212a和第二导向件2223后连接于第二连接端32。
当电机正向旋转时,第一张紧件缠绕于所述卷丝筒上,设缠绕的长度为a,则位于第一滑轨组件1a的上层张紧件231向前传动距离a,由于第一前转向件211a和第一后转向件212a之间的距离是固定的,而张紧件23在第一前转向件211a和第二后转向件212b之间的距离是固定的,因此所述第二滑轨组件1b的下层张紧件232通过第二前转向件211b、第二后转向件212b及第一后转向件212a向第一滑轨组件1a的上层张紧件231传动距离a;又因为第二前转向件211b与第二后转向件212b之间的距离是固定的,因此第二滑轨组件1b的上层张紧件231向下层张紧件232传动距离a,同时第一滑轨组件1a的下层张紧件232通过第一前转向件211a、第一后转向件212a和第二前转向件211b、第二后转向件212b向第二滑轨组件1b的上层张紧件231传动距离a,第三张紧件从所述卷丝筒上释放长度为a。
第一滑轨组件1a的上层张紧件231分别通过第一上固定件221a、第一下固定件222a固定于第一上轨11a、第一下轨13a上;第二滑轨组件1b的上层张紧件231通过第二上固定件221b固定于第二上轨
11b上。同时第一张紧件、第二紧件和第三张紧件的长度都是固定的。当第一张紧件向卷丝筒缠绕长度a时,第一滑轨组件1a的上层张紧件231向下层张紧件232传动距离a,第一滑轨组件1a的上轨11受力向外拉出距离a;第二滑轨组件1b的下层张紧件232向第一滑轨组件1a的上层张紧件231传动距离a,第二滑轨组件1b的上层张紧件231向第二滑轨组件1b的下层张紧件232传动距离a,因此第二上轨11b也向外拉出距离a。同时,第三张紧件从卷丝筒上释放距离a,冰箱向第二滑轨组件1b的上层张紧件231传动距离a,由于第三张紧件的长度是固定的,因此第二滑轨组件1b的第二后转向件212b向前拉出。
当然,当所述固定件22还包括设于第二滑轨组件1b的下轨13上的第二下固定件222b时,也可配合上述电机组件3。需要说明的是,本实施方式的抽屉也可手动开启,通过同步机构2的运作也可实现抽屉的同步进出,电机组件3仅是提供了一自动开闭的作用力,因此,省略电机组件,抽屉仍能实现手动地同步进出。
在本发明另一实施方式中,以张紧件23包括第一张紧件、第二张紧件、第三张紧件及第四张紧件为例,如图20及图21所示,所述电机组件3包括缠绕连接所述第一张紧件和第四张紧件的第一电机组件33,以及缠绕连接第三张紧件及第二张紧件的第二电机组件34,所述第一电机组件33分别收缩或释放第一张紧件和第四张紧件,第二电机组件34分别收缩或释放第三张紧件和第二张紧件,从而使得所述张紧件23移动,进而通过固定件22带动所述中轨12和上轨11移动。
本实施方式的电机组件3与张紧件23的配合情况可参考上一实施方式,在此不再赘述。
进一步地,在本实施方式中,参图22及图23所述同步机构2还包括设置于两个后转向件212之间的张紧套24,两个后转向件212的至少其中之一内设有调节组件4,所述调节组件4与所述张紧套24活动连接,当所述调节组件4处于调紧状态时,所述张紧套24带动所述张紧件23远离所述调节组件4运动直至所述张紧件23在两个后转向件212之间的长度大于两个后转向件212之间的距离,且所述张紧件23在所述张紧套24外的其他部分一直处于拉紧状态,使得第一滑轨组件1a的上轨11或中轨12移动时,所述张紧件23通过固定件22带动第二滑轨组件1b的上轨11或中轨12同向位移相同距离。
这里,相比于无张紧套24的实施例,所述张紧件23在两个后转向件212之间的长度大于两个后转向件212之间的距离;便于安装,且不用担心所述张紧件23在所述张紧套24外的其他部分会发生松弛。另外,为了便于张紧件23的安装,一般会提供较长的张紧件23,当张紧件23组装至固定件22及转向件21上后,张紧件23容易处于松弛状态,本实施方式利用调节组件4可以有效调节张紧套24外的其他张紧件23的松紧度,使得张紧套24外的其他张紧件23始终保持绷紧状态,从而提高同步性及稳定性。
在本发明一具体示例中,所述调节组件4安装在第二滑轨组件1b的后转向件212内,第一滑轨组件1a的后转向件内不存在调节组件,当然,在其他示例中,为了提高调节范围及调节便利性,也可在两个后转向件212内均设置调节组件4。
后转向件212通过基座213固定于丝杆52的后端,在第一滑轨组件1a侧,所述张紧套24与所述张紧件23基座213之间设置有固定套环25,所述固定套环25与所述丝杆52垂直,所述张紧件23在所述固定套环25内的部分与自该部分延伸经过后转向件212后并靠近后转向件212的另一部分相垂直且位于同一平面上,从而可以使得所述张紧件23在滑轨打开或关闭过程中运行顺畅,省力气;同时可以减少所述张紧件23绕过所述后转向件212移动时的磨损,延长寿命。
在第二滑轨组件1b侧,如图12所示,所述调节组件4位于所述基座213内,所述调节组件4包括上调节组件4a及下调节组件4b,上调节组件4a与上转向件2121配合,用于调节穿过上转向件2121的张紧件23的长度,所述下调节组件4b与下转向件2122配合,用于调节穿过下转向件2121的张紧件23的长度。下面。以下调节组件4b为例来详述调节组件的结构。
如图13所示,所述基座213具有相互垂直且导通的第一开口2131及第二开口2132,所述张紧套24的端部位于所述第二开口2132处,且穿设于所述张紧套24内的张紧件23由第二开口2132穿过下转向件2122并延伸至第一开口2131,并由第一开口2131处伸出而固定至固定件22处。需要说明的是,上调节组件4a及下调节组件4b的第一开口2131、第二开口2132可为相互隔绝的开口,以避免串线。
具体的,所述调节组件4包括插销件41及带动所述插销件41运动的同步顶簧42,所述基座213上形成有一第一凸部2133,所述插销件41为中空结构,且所述插销件41的内壁上形成有第二凸部411,所述第一凸部2133与所述第二凸部411围设成一容纳腔(未标示),所述同步顶簧42正好容置于所述
容纳腔内。这里,第一凸部2133及第二凸部411为非完全封闭结构,张紧件23可以依次穿过第二凸部411、第一凸部2133、下转向件2122并延伸至第一开口2131处。
所述同步顶簧42具有相对设置的第一端421及第二端422,所述张紧套24具有靠近所述同步顶簧的第一端部241,所述第一端421抵接所述第一凸部2133,所述第二端422及所述第一端部241分别抵接在所述第二凸部411的两侧。这里,由于张紧套24的直径大于张紧件23的直径,可利用直径差将张紧套24抵持在第二凸部411处,而张紧件23正好可以穿过第二凸部411。
当所述调节组件4处于初始状态时,所述张紧套24抵持第二凸部411,从而使得同步顶簧42限位在第一凸部2133及第二凸部411围成的容纳腔内,插销件41不运动。
当所述调节组件4处于调紧状态时,所述张紧套24带动张紧件23朝向A方向运动,张紧套24脱离第二凸部411,同时,第二凸部411对同步顶簧42的作用力也消失,此时同步顶簧42可推动第二凸部411朝向A方向运动,也就是说,此时同步顶簧42带动插销件41朝向A方向运动,直至第二凸部411再次抵持张紧套24。通过上述调节过程,张紧套24左侧的张紧件23被向A方向拉动一段距离,所述张紧件23在两个后转向件212之间的长度大于两个后转向件212之间的距离,也就是说,此时,张紧件23多余的长度已经被消耗掉,所述张紧件23在所述张紧套24外的其他部分处于绷紧状态。
在本实施方式中,所述同步机构2还包括插片26,所述插销件41的外壁上形成有若干插槽412,所述基座213对应插槽412处形成有至少一插口2134,所述插片26穿过所述插口2134并***所述插槽412内而使得所述插销件41与所述基座213相对固定。这里,当需要调节张紧件23长度时,拔出插片26,使得插销件41可以相对基座213运动,当调节完成后,***插片26,以固定插销件41的位置。
在本实施方式中,所述插销件41的一端还形成有限位端413,所述基座213上形成有与所述限位端413配合的限位面2135,当所述插销件41运动至极限位置时,所述限位端413朝向所述限位面2135运动直至所述限位端413与所述限位面2135彼此干涉。这里,限位面2135及限位端413的设置,一方面,可以避免插销件41在运动过程中脱离基座213,另一方面,也可限制插销件41的可移动范围。
本发明还提供一种冰箱,包括如上所述的滑轨机构100。
综上所述,本发明的滑轨机构100,张紧件23通过转向件21绕置于两个滑轨组件1的固定件22之间,且所述张紧件23交叉连接其中一个滑轨的上轨11与另一个滑轨组件1的下轨13,使得第一滑轨组件1a的上轨11或中轨12移动时,所述张紧件23通过固定件22带动第二滑轨组件1b的上轨11或中轨12同向位移相同距离,实现两组滑轨组件1的同步移动,避免在抽拉过程中因为用力不均匀而造成的偏斜或摇摆现象,且可在抽拉过程中的任意位置锁紧抽屉,整个过程中静音效果好;通过增加辅助中轨组件5,并将转向件21设置于辅助中轨组件5上,上轨11、下轨13之间间隙的变化不会影响到转向件21的正常运作,从而保证同步机构2的稳定性;通过电机组件3与同步机构2的相互配合,所述电机组件3工作时,使得连接于所述电机组件3的所述张紧件23移动,进而通过固定件22带动所述中轨12和上轨11移动,实现自动抽拉抽屉,使用方便;通过设置调节组件4,可以有效调节张紧件23的松紧度,提高用户体验。
