Description

保温板连接结构、冰箱的箱体和冰箱 技术领域
本发明涉及冰箱制造技术领域，具体而言，涉及一种保温板连接结构、具有所述保温板连接结构的冰箱的箱体和具有所述冰箱的箱体的冰箱。
背景技术
传统冰箱都是采用整体发泡的方式进行生产，冰箱的箱体通常为一体式箱体，每个型号的冰箱都要单独设计一整套的模具才能实现生产，用户不能随意定制冰箱的尺寸，不能满足用户的个性化需求；而在冰箱的模块化生产中，发泡板的拼装均是采用外露的偏心钩连接，在连接部位的漏冷严重，能耗难以达标，使得拼装发泡板无法应用于对能效要求高的家用冰箱、酒柜和其他对能耗有要求的产品上，存在改进空间。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述根据本发明第一方面实施例的保温板连接结构10，该保温板连接结构10适于连接冰箱的保温板，当然，本发明的保温板连接结构10还可以用于酒柜、冷冻室等。
如图1-图18所示，根据本发明实施例的保温板连接结构10，包括：第一发泡基板100和第二发泡基板200。
具体而言，保温板连接结构10在图5所示的锁止状态和图3所示的解锁状态之间可切换，或者，保温板连接结构10在图13-图16所示的锁止状态和 解锁状态(未示出)之间可切换。
第一发泡基板100上设有第一连接件110.第二发泡基板200上设有第二连接件210，第二连接件210内具有锁止腔211且锁止腔211内具有锁止件212。
其中，在锁止状态时，第一连接件110伸入锁止腔211且锁止件212止挡第一连接件110脱出锁止腔211，第一发泡基板100的朝向第二发泡基板200的端面与第二发泡基板200的朝向第一发泡基板100的端面正对且齐平；在解锁状态时，第二连接件210允许第一连接件110进出锁止腔211。
根据本发明的保温板连接结构10，可以实现冰箱的柔性化生产，满足用户定制冰箱的个性化需求，并且可以实现多块板体之间的无缝拼装，在拼接处的冷量逸散少。
下面参考图1-图12描述根据本发明一些具体实施例的保温板连接结构10。
根据本发明的一些实施例，如图1-图12所示，第一发泡基板100为挂钉。第二发泡基板200为转动挂钩，转动挂钩在图5所示的锁止位置和图3所示的解锁位置之间可转动。其中，转动挂钩位于解锁位置时，保温板连接结构10切换至解锁状态，此时，转动挂钩允许挂钉进出锁止腔211；转动挂钩位于锁止位置时，保温板连接结构10切换至锁止状态，此时，锁止件212止挡挂钉脱出锁止腔211。
下面参照附图描述根据本发明实施例的保温板连接结构10的工作过程。
首先，相互连接的两个保温板中的一个保温板与第一发泡基板100通过发泡固定成一个整体，另一个保温板与第二发泡基板200通过发泡固定成一个整体。
接着，将转动挂钩转动至解锁位置，并使挂钉进入锁止腔211，如图3所 示，挂钉插入转动挂钩内；然后，将转动挂钩转动至锁止位置，锁止件212将挂钉止挡在锁止腔211内，即，如图5所示，转动挂钩抓住挂钉，实现两个保温板的连接。
图4示出了转动挂钩与挂钉在解锁位置和锁止位置之间的位置时的位置关系，即，转动挂钩处于转动状态时与挂钉之间的位置关系。
由此，利用转动挂钩抓紧挂钉，可以实现相邻保温板之间的连接固定，从而可以使冰箱的箱体由现有的整体式发泡成型变为由多个保温板组合而成，这样，可以最终实现冰箱的外形尺寸、外观等可定制，诸如现有的定制家具橱柜。同时，转动挂钩和挂钉的连接处不外露，可以减少冷量在拼接处的逸散。
在本发明的一些实施例中，如图6-图10所示，转动挂钩上设有与锁止腔211连通的装配口213，锁止件212上构造有与锁止腔211连通的避让槽214。挂钉包括彼此相连的头部111和杆部112。其中，转动挂钩位于解锁位置时允许挂钉的头部111由装配口213进出锁止腔211，转动挂钩从解锁位置转向锁止位置的过程中，挂钉的杆部112逐渐进入避让槽214并沿避让槽214滑动，以便锁止件212最终止挡头部111。可以理解，锁止件212的内侧壁面可以构成锁止腔211的部分内侧壁面，从而结构简单，连接方便。
进一步地，如图6-图9所示，装配口213的宽度大于避让槽214的宽度，头部111的最小宽度大于杆部112的最大宽度，且头部111的最小宽度大于避让槽214的宽度，这样，杆部112进入避让槽214后，向外拉紧挂钉时挂钉的头部111不会从避让槽214处脱出锁止腔211，从而可以将挂钉牢靠地锁止在锁止腔211内。
有利地，如图7-图9所示，转动挂钩构造成中心轴线与转动挂钩的转动轴线重合的圆柱体形，装配口213和避让槽214均贯通转动挂钩的外周壁面，由 此，锁止件212由转动挂钩的周壁的一部分限定出，结构更加简单，且利于转动挂钩的顺畅转动，挂钉直接由装配口213平稳地进入避让槽214并在避让槽214内滑动，方便了装配操作。
在本发明的一些具体实施例中，如图2、图7和图8所示，转动挂钩的至少一表面露出，且转动挂钩的所述至少一表面上设有工具操作槽215，这样，将诸如螺丝刀等工具插入工具操作槽215内便可转动转动挂钩，装配更加便捷。例如，可以在转动挂钩的上表面上设有工具操作槽215。
在本发明的一些实施例中，如图1-图6所示，保温板连接结构10还包括挂钉预埋块300，挂钉连接在挂钉预埋块300上，挂钉预埋块300预埋在第一发泡基板100内，从而挂钉连接在第一发泡基板100上。
在本发明的一些示例中，如图1-图5所示，保温板连接结构10还包括挂钩预埋块400，挂钩预埋块400预埋在第二发泡基板200内，挂钩预埋块400上设有安装腔401，转动挂钩在锁止位置和解锁位置之间可转动地装配在安装腔401内，从而转动挂钩连接在第二发泡基板200上。具体地，安装腔401的侧壁面上设有贯通挂钩预埋块400的安装孔402，以供挂钉从安装孔402进出锁止腔211。
下面参考图13-图18描述根据本发明另一些具体实施例的保温板连接结构10。
根据本发明的一些实施例，如图13-图18所示，第一发泡基板100具有凹槽101，第一连接件110的至少一部分预埋在第一发泡基板100内，也就是说，在成型第一发泡基板100前，将第一连接件110的至少一部分预埋在模具内，待发泡原料(比如聚氨酯)凝固时，第一连接件110即与第一发泡基板100固定连接。第一连接件110从凹槽101处向背离第一发泡基板100的方向突出， 也就是说，第一连接件110的一部分伸出第一发泡基板100外。
第二发泡基板200具有凸台201，凸台201的形状与凹槽101相同，且凸台201配合在凹槽101内。
第二连接件210的至少一部分预埋在第二发泡基板200内，也就是说，在成型第二发泡基板200前，将第二连接件210的至少一部分预埋在模具内，待发泡原料(比如聚氨酯)凝固时，第二连接件210即与第二发泡基板200固定连接。第二连接件210具有锁止腔211，锁止腔211位于凸台201内，且锁止腔211朝向第一发泡基板100敞开。
可以理解的是，将第一发泡基板100的凹槽101与第二发泡基板200的凸台201正对，并进行对接，第一连接件110从第二连接件210的锁止腔211的敞开端伸入锁止腔211内，并与第二连接件210卡接，此时，第二发泡基板200的凸台201刚好嵌入第一发泡基板100的凹槽101，第一发泡基板100的朝向第二发泡基板200的端面与第二发泡基板200的朝向第一发泡基板100的端面正对且齐平，这样，第一发泡基板100与第二发泡基板200之间无外露的连接件，在拼接处由于凸台201和凹槽101的配合，可以有效地减小冷量逸散。
有利地，如图13-图17所示，凹槽101和凸台201可以均为楔形。这样，第一发泡基板100和第二发泡基板200的嵌入效果好，冷量不易在拼接处逸散。具体地，凹槽101和凸台201可以均具有梯形截面。
在本发明的一些实施例中，如图13-图16所示，凹槽101和凸台201间隔开，第一发泡基板100的朝向第二发泡基板200的端面止抵第二发泡基板200的朝向第一发泡基板100的端面。
换言之，在将第一发泡基板100和第二发泡基板200拼接完成时，第一发 泡基板100的朝向第二发泡基板200的端面止抵第二发泡基板200的朝向第一发泡基板100的端面，这样，第一发泡基板100与第二发泡基板200之间可以实现无缝；凹槽101和凸台201间隔开，则可以防止由于生产误差造成的第一发泡基板100的端面与第二发泡基板200的端面无法止抵的现象。
在本发明的一些具体实施例中，如图14、图16和图17所示，第一连接件110包括杆体113和卡接头114，杆体113的一端与第一发泡基板100固定连接，也就是说，杆体113的一端可以预埋在第一发泡基板100内。杆体113的该端还可以设有抓泡结构，比如抓泡结可以为底板，抓泡结构预埋在第一发泡基板100内，这样第一连接件110与第一发泡基板100之间的抓泡效果更好，即第一连接件110不易从第一发泡基板100脱离。球体与杆体113的另一端相连。
杆体113和卡接头114中的至少一个为金属件或至少一个为塑料件。比如，杆体113和卡接头114可以为形成为一体的金属件；或者，杆体113和卡接头114可以为形成为一体的塑料件，需要说明的是，塑料件的强度需要满足要求。杆体113可以为圆柱形，卡接头114可以为球形，且杆体113的轴线过卡接头114的球心。其中，卡接头114可以为整球形，也可以为整球切削部分形成的部分球形。
第二连接件210包括空心柱体216，空心柱体216可以形成锁止腔211，在锁止状态时，杆体113的至少部分和卡接头114伸入锁止腔211，且卡接头114与锁止件212卡接相连。
具体地，锁止件212为两根贯穿空心柱体216的弹性杆，两根弹性杆间隔开设置，在锁止状态时卡接头114卡接在两根弹性杆之间。可以理解的是，两根弹性杆的间距小于卡接头114的直径，在装配时，卡接头114撑开两根弹性 柱，并挤入两根弹性柱的下方，两根弹性柱恢复形变，并将卡接头114卡住。
进一步地，两根弹性杆平行设置，满足：0.5D≤L≤0.9D，其中，L为两根弹性杆的间距，卡接头114可以为球形，D为卡接头114的直径。这样，卡接头114易于卡入弹性杆下方。卡接头114的直径可以根据实际的需要调节，通过改变卡接头114的直径可以改变锁紧或者拆卸时力的阈值。弹性杆的弹性系数可以根据实际需要进行设计，两弹性杆之间的距离也可以根据实际的需要进行调节。
在本发明的一些实施例中，如图17和图18所示，第二连接件210还包括：底座217和加强筋218，底座217与空心柱体216的远离第一发泡基板100的一端相连，加强筋218连接在空心柱体216与底座217之间。
有利地，加强筋218为多个且沿轴向延伸，多个加强筋218沿周向间隔开设置。底座217和加强筋218可以使第二连接件210与第二发泡基板200之间的抓泡效果更好，即第二连接件210不易从第二发泡基板200脱离，且第二连接件210的强度和刚度更好，在发泡过程中，保证空心柱体216不发生形变。其中，第二连接件210可以为塑料件。
如图1-图18所示，根据本发明第二方面实施例的冰箱的箱体1，包括彼此相连的多个保温板20和根据本发明第一方面实施例所述的保温板连接结构10。
例如，先将需要相互连接的两个保温板20中的一个保温板20与第一发泡基板100发泡成型，另一个保温板20与第二发泡基板200发泡成型；接下来，挂钉伸入转动挂钩的锁止腔211中实现初步定位；然后，转动转动挂钩至锁止位置，锁止件212将挂钉拉紧固定，从而最终实现两个保温板20之间的固定连接。其中，相互连接的两个保温板20可以彼此垂直设置。
根据本发明实施例的冰箱的箱体1，通过利用如上所述的保温板连接结构10，可以将现有的整体式冰箱箱体设计为由多块保温板20拼装而成的箱体1，从而可以实现冰箱的柔性化生产，满足用户定制冰箱的个性化需求。同时，多块保温板20无缝拼装，在拼接处的冷量逸散少，从而利于提高冰箱的能效。
根据本发明第三方面实施例的冰箱，包括根据本发明第二方面实施例所述的冰箱的箱体1和门体(图中未示出)，门体可转动地设在箱体1上以打开和关闭箱体1。
根据本发明实施例的冰箱，通过利用如上所述的冰箱的箱体1，可以实现柔性化生产，满足用户定制冰箱的个性化需求，并且，能效高。
