Abstract

一种用于可折叠容器的侧板（4）及包括该侧板的可折叠容器（100），该侧板（4）由内外侧板（4B、4A）连接而成，侧板（4）内设有加强件（6），加强件（6）为一体件，其至少一部分位于侧板（4）中部，至少另一部分位于侧板（4）左右两端。该侧板（4）使箱体堆垛能力更强，并使得箱体在容积最大化的同时抗形变能力更强，可靠性得到提升。

Description

可折叠容器及其侧板 技术领域
本发明涉及物流运输领域，具体涉及一种可折叠容器及其侧板。
背景技术
现有大型折叠容器一般规格如1200×1000×1000、1220×1220×1170等，其尺寸相对较大，为了便于在容器取物，通常在侧板中部靠上的位置设置小门，使得更有利于操作，但是，现有的大型容器侧板设置小门，其侧板与小门的铰接方式单一，在侧壁开小门方便取物的同时，这也给开小门的侧壁在强度上带来一定程度的损失，侧壁开小门后，侧壁整体抗变形能力减弱，随之而来的是箱体侧壁在箱体满负载之后更易向着箱体外缘鼓出，像这样的形变既给产品本身带来安全隐患，同时也会在运输方面，对于相对固定尺寸的集装箱，形变会导致装箱时，容器与容器之间的间隙缩小甚至是没有，导致无法将一定数量的容器装载到集装箱内，像已公开的专利WO2010031456，其容器侧板设置小门后，因小门与侧板的连接仅靠小门与侧板导轨连接，其结构单一，而且小门厚度相对于侧板厚度较薄，在其侧板主体抗变形能力较弱情况下其强度更弱于侧板主体，这两种因素导致箱体满载货物时时，货物对侧板的涨力易使得侧板和小门形变，形变后导致容器在其上堆垛的箱体限位失效，运输搬运中，箱体易掉落造成损失，亦是使容器相互间的摆放间隙增加，在限定的存储空间(集装箱)不能最大化利用空间，造成给存储运输成本的增加。

通过在侧板主体内设置加强件，从整体上增加箱体满载时侧板受货物张力而变形的能力，通过小门上端相对刚性完整的整体与侧板的内置加强件组合， 使得在箱体满载情况下，箱体侧板受张力时，箱体侧板的整体变形量小，又使得箱体堆垛和装箱都拥有良好的适应性，有效解决容器侧板在限定厚度情况下的容积最大化与适用性等功能。
在本发明中，横梁部分主要是增加在箱体满载时侧板向外的抗弯能力，而立柱部分是在侧板有形变趋势时，将横梁两端的应力均匀向立柱末端传递，从而消除侧板变形后将应力通过横梁两端释放而造成的侧板破损。
此外，第一附加加强件通过横梁与立柱的衔接形成一个肩部，使得侧板与小门配合的肩部拥有向外抗扭曲的能力，使得侧板在既定厚度的情况下，通过内置的加强件从整体上明显改善侧板的抗变形能力。
因此，本发明的侧板使得箱体在使用过程中堆垛能力更强，在容积最大化的同时箱体抗形变能力加强，可靠性得到提升。

具体实施方式
以下将结合附图对本发明的较佳实施例进行详细说明，以便更清楚理解本发明的目的、特点和优点。应理解的是，附图所示的实施例并不是对本发明范围的限制，而只是为了说明本发明技术方案的实质精神。
根据本发明的一方面，用于可折叠容器的侧板由内外面板连接而成，以及 侧板内设有为一体件的加强件，其中加强件的至少一部分位于侧板中部，以及加强件的至少另一部分位于侧板左右两端。在本文中，侧板中部指的是沿侧板高度方向从上往下的1/3长度至2/3长度以及从左往右或从右向左的1/3宽度至2/3宽度之间的区域。侧板两端指的是侧板从左往右或从右往左的0至1/3宽度或2/3宽度至1个宽度之间的区域。
根据本发明的另一方面，可折叠容器的侧板内设有加强件，该加强件包括横向加强件和纵向加强件，其中，横向加强件在侧板内横向延伸，纵向加强件设置于所述侧板的两端，以及横向加强件与所述纵向加强件为一体件。所谓一体件，指的是各个构件连接形成一个整体，且各个构件相互之间不能相互活动，可以通过各个构件一体形成从而形成一体件，或可以通过各个相互固定连接形成一体件。例如，横向加强件和纵向加强件一体形成或通过焊接形成一体件。本发明中的侧板包括外侧板和内侧板，并由外侧板和内侧板相互连接(比如焊接)形成，从而可以将加强件方便地布置于侧板内。较佳地，该侧板为双光面侧板。
根据本发明的再一个方面，可折叠容器的侧板设有小门，且在该侧板内设有加强件。该加强件通常包括至少两根立柱、至少一根横梁以及第一附加加强件，其中，横梁设置于小门下方，第一附加加强件设置于侧板的位于小门两端的部分上，以及横梁固定连接于两根立柱并位于两根立柱之间，且第一附加加强件至少固定连接于横梁和立柱之一上。
以下结合图1-8对发明的一种实施方式进行详细说明。
图1是本发明的可折叠容器100的立体图，其中小门处于关闭状态。图2是本发明的可折叠容器100的立体图，其中小门处于打开状态。如图1-2所示，可折叠容器100包括底座1，一对相对侧板2和一对相对侧板3、4，其中，在侧板4上设置有小门5。
小门包括第一部分52和第二部分53，第二部分53位于小门5的上部(即小门关闭时位于上方的部分)，第一部分52位于小门5的下部(即小门关闭时位于下方的部分)，第二部分53的宽度比第一部分52的宽度大，较佳地，第二部分53的宽度是第一部分52的宽度的1.2～1.5倍。
图3为侧板4的剖视图，如图3所示，在小门5的底部设有铰链42，侧板4与小门5通过铰链42相互连接，从而小门5可以绕铰链42相对于侧板4转动 而实现开启或关闭。有关铰链42的详细情况请参见中国发明专利CN102758572A，本文不再详细描述。
在本实施例中，小门5呈T字形，第一部分52和第二部分53之间设置成通过弧形连接过渡，从而第一部分52、第二部分53的侧边形成曲线轮廓。
参照图2，小门5的两端设置有第一咬合部521和第二咬合部531，其中第二咬合部531设置于第二部分53的底部，第一咬合部521设置于第一部分52的左、右端壁。根据需要可以在第二部分53的底部设置多个第二咬合部531，以及可以在第一部分52的左、右端壁设置多个第一咬合部521。第一部分521的宽度从上端向下端逐渐减小，第一咬合部521设置于第一部分52的左、右端壁上。
在本实施例中，由于第一部分52和第二部分53连接形成曲线轮廓，从而第二咬合部531以及第一咬合部521设置于曲线轮廓上。
图4是本发明侧板4的立体分解图，图5是本发明的侧板的立体图，图6是图5的侧板沿线A-A剖开的剖视图，图7是图5的侧板沿线B-B剖开的剖视图，如图4-7所示，侧板4包括外侧板4A和内侧板4B，在内侧板4B的内表面设置加强筋，加强件6设置于外侧板4A和内侧板4B之间。
如图4所示，在侧板4上设有与小门5配合的开口40，在开口40的两侧设有第一咬合结构43和第二咬合结构44，其中，第二咬合结构44和第二咬合部531配合，第一咬合结构43和第一咬合部521配合。在本实施例中，为了与小门5两端的曲线轮廓配合，开口40两侧形成有与小门5的曲线轮廓配合的形状。
图8是根据本发明一实施例的加强件6的立体图，如图8所示，加强件6包括两根立柱61、横梁62和63以及第一附加加强件64，横梁62和63分别固定连接于两根立柱61并位于两根立杆61之间，且横梁63位于横梁62上方。第一附加加强件63包括横杆642和立杆641，立杆641固定连接于横梁63，横杆642固定连接于立柱61，横杆642和立杆641相互固定连接。由于横梁63同时连接两根立杆641和两根立柱61，因此，设置横梁63的横截面积大于横梁62的横截面积，以加强加强件6的强度，从而进一步增强侧板4的强度。
在本实施例中，加强件6的两根立柱61、横梁62和63以及第一附加加强件64的横杆642和立杆641全部由钢管制成，然而本领域的技术人员可以理解，加强件6也可以由其它加强材料制成，比如铝合金管和/或碳纤维管等。
回到图3，当加强件6设置于侧板4内以后，横梁62和63位于铰链51的下方，立柱61位于侧板4的两端靠近边缘的部分，第一附加加强件64设置于铰链42的上方，并位于第一咬合结构43的外侧，具体地，侧板4还设有把手41，横杆642位于把手41的下方，立杆641位于把手41的内侧(位于把手41的靠近侧板4的中部的一侧)。
较佳地，立柱61距离最近一侧的侧板端部的距离为0.01-0.5倍，横梁63距离小门的下端的距离为侧板高度0.01-0.5倍。
参照图3-4，小门5包括外侧壁5A和内侧壁5B，内侧壁5B上设有加强筋，在外侧壁5A和内侧壁5B之间还设有第二附加加强件51。第二附加加强件51设置于小门5的中部并从小门5的左端向右端延伸，第二附加加强件51优选为横截面为方形的钢管，然而也可以为其它加强材料，例如为铝合金管和/或碳纤维管等。较佳地，当小门5在侧板4上处于关闭状态时，立杆641的上端与第二附件加强件51大致位于同一高度。
在本发明的另一实施例，第一附加加强件64可以仅仅包括立杆641，立杆641与横梁63固定连接。在本发明的另一实施例，第一附加加强件64可以仅仅包括横杆642，横杆642与立柱61固定连接。在本发明的另一实施例，加强件6可以仅仅包括一根横梁63，省略横梁62。在本发明的另一实施例，第一附加加强件64可以为其它形状的杆件，比如弯曲状的杆件或折弯一定角度的杆件。
下面结合图9对本发明另一实施例进行说明。如图9所示，本实施例与前述实施例的区别在于，加强件7与加强件6不同。与加强件6相比，加强件7仅仅包括两根立柱61、横梁63以及第一附加加强件74，横梁63固定连接于两根立柱61并位于两根立杆61之间。第一附加加强件74仅包括立杆641，立杆641固定连接于横梁63。当加强件6设置于侧板4内以后，横梁63位于铰链51的下方，立柱61位于侧板4的两端靠近边缘的部分，第一附加加强件64设置于铰链42的上方，并位于第一咬合结构43的外侧，具体地，侧板4还设有把手41，立杆641位于把手41的内侧(位于把手41的靠近侧板4的中部的一侧)。
下面结合图10-11对本发明的另一实施例进行说明。图10是本实施例加强件的立体图，图11是本实施例侧板的立体图。如图10所示，加强件8包括相互交叉连接的第一杆件81和第二杆件82以及设置于第一杆件81与第二杆件82之间的第三杆件83，第三杆件83的两端分别连接于第一杆件81和第二杆件82。 第一杆件81和第二杆件82的上端分别连接有第四杆件84和第五杆件85，第四杆件84和第五杆件85布置于侧板4的小门5左右两端的部分上。在本实施例中，第一杆件81和第二杆件82交叉连接，从形成近似“X”构型，在第一杆件81和第二杆件82之间设置第三杆件83，由于第三杆件83同时连接到第一杆件81和第二杆件82，从而将第一杆件81和第二杆件82牢固连接在一起。
其中，第一杆件81和第二杆件82的上端分别向两侧延伸出平行部分811和821，第四杆件84和第二杆件85分别连接于平行部分811和821上，较佳地，第三杆件84和第五杆件85与平行部分811和821垂直。
如图11所示，当加强件8设置于侧板4内以后，第三杆件83位于铰链51的下方，第一杆件81和第二杆件82的交叉部分位于侧板4的中部，第一杆件81的上端811和下端812位于侧板4的左端或右端，以及第二杆件82的上端821和下端822位于侧板4的右端或左端。第四杆件84和第五杆件85设置于铰链42的上方，并位于第一咬合结构43的外侧，具体地，侧板4还设有把手41，第四杆件84和第五杆件85分别位于把手41的内侧(即位于把手41的靠近侧板4的中部的一侧)。
在本发明中，连接可以是两个构件相互接触形成，也可以是两个构件一体形成，且凡是提到用固定连接的地方，都可以通过焊接实现。当然，也可以使用本领域的其它连接方式实现。
本发明的侧板设有外观大致成“T”字形的小门，像这样设置的小门上端相对较宽，最大程度的保持侧板上端的完整，将上端这一相对刚性的主体延长，使得最大程度上减小小门因受满载货物时内张力影响的形变。
同时在侧板主体内设置加强件，从整体上增加箱体满载时侧板受货物涨力而变形的能力，通过小门上端相对刚性完整的整体与侧板的内置加强件组合，使得在箱体满载情况下，箱体侧板受张力时，箱体侧板的整体变形量小，又使得箱体堆垛和装箱都拥有良好的适应性，有效解决容器侧板在限定厚度情况下容积最大化与适用性等问题。
在本发明中，横梁部分主要是增加在箱体满载时侧板向外的抗弯能力，而立柱部分是在侧板有形变趋势时，将横梁两端的应力均匀向立柱末端传递，从而消除侧板变形后将应力通过横梁两端释放而造成的侧板破损。
此外，第一附加加强件通过横梁与立柱的衔接形成一个肩部，使得侧板与 小门配合的肩部拥有向外抗扭曲的能力，使得侧板在既定厚度的情况下，通过内置的加强件从整体上显著改善侧板的抗变形能力。
以上已详细描述了本发明的较佳实施例，但应理解到，在阅读了本发明的上述讲授内容之后，本领域技术人员可以对本发明作各种改动或修改。这些等价形式同样落于本申请所附权利要求书所限定的范围。
