具体实施方式
下面结合附图对本发明作进一步详细描述。
图1为本发明实施例的一种床体结构的结构示意图(无柔质支撑层)、图2为本发明实施例的一种床体结构的结构示意图(有柔质支撑层)，如图1和图2所示，本发明提供的床体结构包括：承托机构1、翻转机构2、底座3和柔质支撑层4；所述翻转机构2设于所述承托机构和所述底座3之间，所述柔质支撑层4覆盖于所述承托机构1顶部；所述承托机构1包括至少两个支撑组件5；在平铺状态下，各个所述支撑组件5依序水平排列于所述底座3的顶部；在展开状态下，所述翻转机构2使至少一个所述支撑组件5相对于所述底座向上翻转。
翻转机构2可根据需要调整的支撑组件5的数量进行设置，一般设置2至3个就能满足大部分承托机构1变形的需要，支撑组件的具体数量根据需要设置。
承托机构1和柔质支撑层4组成支撑面，并以此代替传统的木板支撑面，支撑组件5可以选用多种多样的材质和形状支撑件的制成，比如金属 管，将金属管连接成四边形作为支撑组件5，最好采用规则的四边形，方便合理安排内部空间控制整床的体积，最重要的是彻底舍弃床板，不再需对板材进行切割、钻孔、安装等工序，省去了中间繁杂的工序，节约大量时间和人工，整床的生产时间缩减30％至40％，生产效率大大提高。
图3为本发明实施例的一种床体结构的俯视示意图，如图3所述，所述承托机构1还包括：柔质包覆结构101；所述柔质包覆结构101包覆于所述支撑组件5的外壁。
柔质包覆结构101包裹住支撑组件5外侧面，增加柔质包覆结构101与支撑组件5的接触面积，可以使柔质包覆结构101更加稳固。床在使用时，一般将床垫水平安放在承托机构1的顶面，承托机构1的顶面被床垫全部遮盖，但是承托机构1的侧边还是可以接触和观察到的，将支撑件直接暴露在外既不美观也不安全，尤其是在使用者座在床边的时，使用者的腿部会与承托机构1的外侧接触，考虑到承托机构1多采用金属和各种金属固定件，与人体发生接触时，有可能对人造成损伤。
柔质包覆结构101可包覆于承托机构1的整体或局部，可选择仅包覆于承托机构1最外侧的支撑件表面，柔质包覆结构101可采用裹EPE(珍珠棉)、乙烯-醋酸乙烯酯共聚物(EVA)、海绵或空心塑料型材制成，柔质包覆结构101内腔的形状与支撑件外壁贴合，用粘合剂固定后形成整体，赋予承托机构1外侧柔软、流畅的轮廓，更加美观，还可减轻使用者与承托机构1直接发生碰撞导致的损害。克服了简单的外观无法与高端产品的功能进行匹配，导致无木板高端床无法形成实际销售的情况，在实际销售中效果非常好，提高了销量。
另外，通过调整柔质包覆结构101截面形状，可以形成各种各样的外形，提高产品的美观度和舒适度，满足不同的客户需求。图2为本发明实施例的一种床体结构的结构示意图(有柔质支撑层)、图3为本发明实施例的一种床体结构的俯视示意图、图4为本发明实施例中卡槽局部放大示意图、图5为本发明实施例中被柔质包覆结构包覆的支撑件的截面图，如图2至5所示，所述承托机构还包括：卡槽102和卡紧件103；所述卡槽102设置于所述承托机构1，所述卡紧件103可拆卸的设置于所述卡槽102 内部；所述柔质支撑层4的边沿与所述卡紧件103连接；所述柔质包覆结构101设有与所述卡槽102对应的缺口。
柔质支撑层4可选用无纺布复合一层底布，底布可以是起毛布、3D网眼布等材料，增加支撑强度；涤棉、阻燃棉：增加强度，并起到阻燃作用；也可以增加防水涂层或复合防水布；还可以复合海绵，增加柔软度。无纺布还可以用超声波布替代，也可以用全面料(不用无纺布)再复合其他材质。
卡槽102是在需要安装卡紧件103的支撑件上设一开口并向其内部扩展，形成开放式容置空间，卡紧件103可拆卸的固定在卡槽102中，方便、快捷地固定柔质支撑层4。在不增大承托机构1体积的情况下，设置卡槽102、卡紧件103实现对柔质支撑层4的绷紧。
在支撑件上包裹柔质包覆结构101，柔质包覆结构101留有与卡槽102位置对应的缺口，以便安装卡紧件103；再用柔质支撑层4覆盖于承托机构1的顶面，柔质支撑层4的边缘从承托机构1的边沿垂落，柔质包覆结构101外侧被柔质支撑层4包裹，承托机构1四周边缘的支撑件可选用带有卡槽102的开口管，卡紧件103将柔质支撑层4可拆卸地固定在卡槽102内并张紧柔质支撑层4，使得柔质支撑层4平整、无褶皱，卡紧件103由于柔质支撑层4的预紧力而无法从开口管的开口处滑出。简化了生产工艺，提高床体的美观度，还可防止承托机构1直接接触床垫损坏床垫；紧绷的柔质支撑层4包紧了柔质包覆结构101，既美观又有利于防止柔质包覆结构101变形。
图1为本发明实施例的一种床体结构的结构示意图(无柔质支撑层)、图6为本发明实施例的一种床体结构的局部放大结构示意图，如图1和图6所示，所述柔质包覆结构101的顶面与所述支撑组件5的顶面齐平。
柔质包覆结构101的顶面与支撑组件5顶面齐平，即与承托机构1的顶面齐平，此时床垫放置于承托机构1的顶面也不对柔质包覆结构101造成挤压，同时柔质包覆结构101完全遮住了承托机构1的侧面，与床垫的下边沿连成一体，给使用者提供美观的外观，还有利于保持柔质包覆结构101预设的形状。
优选地，柔质包覆结构101的顶面略高于支撑组件5的顶面，约0.2厘米至0.5厘米。高出支撑组件5顶面的柔质包覆结构101，可作为床垫和支撑框架的缓冲，柔性材料制成的柔质包覆结构101受到少许的挤压并不会造成其形变，还能减少震动，给使用者更好的体验。
进一步地，所述支撑组件5由多个支撑件构成，所述卡槽102设置在位于所述承托机构1边缘的所述支撑件上。
当安装柔质支撑层4时，卡槽102设置在承托机构1边缘的支撑件上，为我们选择大块柔质支撑层4整体遮盖承托机构1顶面提供了方便。如选择面积大于承托机构1顶面的柔质支撑层4，将柔质支撑层4覆盖于其顶面后，将超出承托机构1顶面的柔质支撑层4用卡紧件103卡入卡槽102内，既方便又快捷，而且整张柔质支撑层4安装好后，即使不放置床垫，也能提供良好的外观，提高产品的档次。
优选地，所述卡槽102在设置在同一水平高度并形成一个完整的闭环。保证了柔质支撑层4张紧力的均匀，也更加牢固。
图2为本发明实施例的一种床体结构的仰视结构示意图、图5为本发明实施例中被柔质包覆结构包覆的支撑件的截面图，如图2和图5所示，所述卡槽102的开口朝向所述支撑组件5的中部。
卡槽102的开口可以为支撑件外壁的任意位置，都可以满足卡紧柔质支撑层4的需求，但最好将卡槽102开口全部设置在支撑组件5的内侧，安装柔质支撑层4时就需要绕柔质包覆结构101大半圈以上，柔质支撑层4包裹于柔质包覆结构101的外侧并最终被卡紧件103固定于卡槽102中，柔质支撑层4形成一个360度的包裹，可以将柔质包覆结构101及整个框架进一步固定在一起，使柔质包覆结构101不会晃动，既有利于保持柔质包覆结构101的形状，也有利于保持柔质支撑层4的张紧。
图5为本发明实施例中被柔质包覆结构包覆的支撑件的截面图，如图5所示，所述柔质包覆结构101具有自上而下向内侧逐渐倾斜的外斜面1011和自下而上向内侧逐渐倾斜的内斜面1012；所述柔质包覆结构101包覆于位于所述承托机构1边缘的所述支撑件。
柔质支撑层4从卡槽102开口向下延伸至所述柔质包覆结构101的底 部后沿着柔质包覆结构101的轮廓向上形成对柔质包覆结构101的半包围后到达承托机构1的顶面，柔质支撑层4依托柔质包覆结构101一端的倾斜面设计，使柔质支撑层4形成预紧力，防止卡紧件103被拉出，仅通过弹力作用就使卡紧件卡合于卡槽内而不向外松开。
图7为本发明实施例一种床体结构的细节结构示意图，如图7所示，所述承托机构1包括：第一支撑组件6、第二支撑组件7、第三支撑组件8、第四支撑组件9和第五支撑组件10；其中，所述第一支撑组件6和所述第二支撑组件7于交界处枢轴连接，所述第三支撑组件8、所述第四支撑组件9和所述第五支撑组件10于交界处枢轴连接；所述第一支撑组件6包括：第一支撑件601、第二支撑件602、第三支撑件603和第四支撑件604，所述第二支撑组件7包括：第五支撑件701、第六支撑件702、第七支撑件703和第八支撑件704，所述第三支撑组件8包括：第九支撑件801、第十支撑件802、第十一支撑件803和第十二支撑件804，所述第四支撑组件9包括：第十三支撑件901、第十四支撑件902、第十五支撑件903和第十六支撑件904，所述第五支撑组件10包括：第十七支撑件1001、第十八支撑件1002、第十九支撑件1003和第二十支撑件1004；相互平行的所述第一支撑件601和所述第二支撑件602垂直于相互平行的所述第三支撑件603和所述第四支撑件604，所述第一支撑件601、所述第二支撑件602和所述第三支撑件603固定连接，所述第四支撑件604搭接于所述第一支撑件601和所述第二支撑件602的顶部；相互平行的所述第五支撑件701和所述第六支撑件702垂直于相互平行的所述第七支撑件703和所述第八支撑件704，所述第七支撑件703和所述第八支撑件704搭接于所述第五支撑件701和所述第六支撑件702的顶部；相互平行的所述第九支撑件801和所述第十支撑件802垂直于相互平行的所述第十一支撑件803和所述第十二支撑件804，所述第十一支撑件803和所述第十二支撑件804搭接于所述第九支撑件801和所述第十支撑件802的顶部；相互平行的所述第十三支撑件901和所述第十四支撑件902垂直于相互平行的所述第十五支撑件903和所述第十六支撑件904，所述第十五支撑件903和所述第十六支撑件904搭接于所述第十三支撑件901和所述第十四支撑件902的 顶部；相互平行的所述第十七支撑件1001和所述第十八支撑件1002垂直于相互平行的所述第十九支撑件1003和所述第二十支撑件1004，所述第十七支撑件1001、所述第十八支撑件1002和所述二十支撑件904固定连接，所述第十九支撑件1003搭接于所述第十七支撑件1001和所述第十八支撑件1002的顶部。
支撑件相互连接形成长方形的支撑组件5，多个支撑组件5组成承托机构1，每个支撑组件5就是一个支撑面，多个支撑面组成用于安放床垫的床面。日常生活中，床的支撑面都是完全平整的。搭接则是在支撑件之间构建一定的高度差，该支撑组件中的支撑件不处于同一平面，有利于柔质包覆结构101附着在位于承托机构1边缘的支撑件上面，增加对于柔质包覆结构101的支撑，并且柔质包覆结构101的顶面与支撑组件5的顶面形成同一平面，即与在平铺状态的承托机构1上表面形成一个完整的支撑面，承托机构1可以更多的承托人体重量，防止柔质包覆结构101被压扁，保持外观的完整性。
此外，还可在各支撑组件上继续增加支撑件作为加强杆和设备安装基础。如在第一支撑组件新增支撑件为床垫提供更好的支撑，或作为安装按摩器的基础。
图1为本发明实施例的一种床体结构的结构示意图(无柔质支撑层)、图6为本发明实施例的一种床体结构的局部放大结构示意图，如图1、图5和图6所示，支撑件相互搭接的接触区域5001位于被搭接的支撑件的顶面区域5002的一部分，被搭接的支撑件的顶面区域的另一部分被所述柔质包覆结构101所包覆，所述柔质包覆结构的接触面5003与搭接的支撑件的端面5004相接触。
例如，第四支撑件604搭接于第一支撑件601，第四支撑件604与第一支撑件601相互搭接的接触区域位于被搭接的第一支撑件601的顶面区域的一部分，第一支撑件601的顶面区域的其他部分被柔质包覆结构101所包覆，搭接的第四支撑件604的两端的端面均与柔质包覆结构的接触面相接触，第四支撑件604的顶面与柔质包覆结构101的顶面相齐平，构成一无缝平整的床面，将柔质支撑层覆盖于床体上时，床体不会有其他突出 部分，外表体现为平滑的整体。
柔质包覆结构101上面开有缺口刚好包裹搭接的端部，增加柔质包覆结构101纵向和横向的支撑力，当人体的重量压在床边缘的柔质包覆结构101上时，柔质包覆结构101能够获得更好地支撑并保持形状，这种结构使得床体边缘即有软包部分，可以让人体感觉很舒适，同时又有刚性好的部分，可以进行有效的承重。
此外，在集装箱运输过程中，床与床都是堆叠起来的，位于底部的床需要承受巨大的重量，因此对于传统的软包的木板床，软包往往容易被压扁，而这种结构设计可以有效的解决这个问题，所有的重量均由铁架进行承重。
图3为本发明实施例的一种床体结构的俯视示意图、图8为本发明实施例中滑轮组件结构示意图，如图3和图8所示，所述翻转机构2包括：驱动装置201、翻杆202、滑轨203、滑轮组件204；所述驱动装置201分别与所述翻杆202和所述底座3枢轴连接，所述驱动装置201推力的水平方向与相应地所述支撑组件5翻转的水平方向相同；所述翻杆202垂直于所述支撑组件5翻转的水平方向，所述翻杆202的两端分别设有所述滑轮组件204；所述滑轨203设置于所述承托机构1，所述滑轨203延伸的水平方向与所述驱动装置201推力的水平方向平行；所述滑轮组件204在所述滑轨203中可滑动，所述滑轮组件204包括：第一滑轮2041、第二滑轮2042和支撑杆2043；所述第一滑轮2041与所述支撑杆2043的一端枢轴连接，所述第二滑轮2042与所述支撑杆2043的中部枢轴连接，所述支撑杆2043的另一端与所述底座3枢轴连接；所述支撑杆2043的中部向所述支撑组件5方向突起呈钝角；在所述承托机构1处于所述平铺状态时，所述第二滑轮2042与所述滑轨203接触且可在所述滑轨203底面滑动；在所述承托机构1展开过程中，所述第一滑轮2041和所述第二滑轮2042均与所述滑轨203接触且可在所述滑轨2043底面滑动；所述翻杆202与所述支撑杆2043垂直连接，所述翻杆202与所述支撑杆2043的连接点位于所述支撑杆2043与所述底座3枢轴连接处至所述第二滑轮2042之间。
成对的滑动组件的一端分别与底座3枢轴连接，支撑杆2043采用弯 曲结构，即中部呈钝角，该钝角选用150度左右比较好，驱动装置201工作时，带动翻杆202以滑轮组件204与底座3枢轴连接处为转轴转动，第二滑轮2042在对应的滑轨203上滑动，推动相应的支撑组件5，在支撑组件5相对于底座3翻转至20度至30度时，第一滑轮2041也与该滑轨203底面接触并在其底面滑动，仅一个滑轮时，支撑组件翻转20度至30度时会出现非常大的阻力，增设另一个滑轮可以克服该阻力，保证支撑组件5平稳翻转。
当翻转机构2推动第四支撑组件9时，第四支撑组件9以第三支撑组件8和第四支撑组件9之间的枢轴为转轴向上翻转，翻转的水平方向与第一滑轮2041至第二滑轮2042的水平方向相同；此外，如第四支撑组件9在第二滑轮2042至第一滑轮2041的水平方向上设有第五支撑组件10，且第五支撑组件10的一端与其枢轴连接，那么第五支撑组件10与第四支撑组件9的枢轴连接端也会跟随第四支撑组件9相对于底座3翻转。此时，仅一个翻转机构2就可以促使两块枢轴连接的床板一同翻转变形；再者，还可在第五支撑组件10的另一端增设连杆1005，通过连杆1005与底座3枢轴连接，第四支撑组件9翻转至一定角度时，第五支撑组件10的另一端会以连杆1005为旋转半径翻转至一定高度，连杆1005的长度根据床体具体结构调整，过长或过短都会导致第五支撑组件10的另一端无法翻转抬升，给人更舒适的体位。这样，可以减少床体内部翻转机构，且不影响支撑组件翻转的功能，还可减轻床体重量，缩小床体体积，降低生产成本。
进一步地，所述底座3固定设置有承重部301；在所述承托机构1处于所述平铺状态时，所述承重部301位于所述支撑杆2043介于所述第一滑轮2041和所述第二滑轮2042之间的正下方。
当底座3不能给予翻转机构2支撑时，在承托机构1平铺时，翻转机构2在空间上会超出底座3的对面，增大了床体的体积，通过设置承重部，将翻转机构2限制在底座3底面与承托机构1底面之间的空间内，缩小体积，既方便运输又更加美观。
图9为本发明实施例中翻转机构力臂示意图，如图9所示，根据如下公式(1)和公式(2)调整所述翻转机构在所述平铺状态下的水平方向的 重力臂、第一阻力臂和第二阻力臂的长度和位置，以减小所述翻转机构在所述平铺状态下的竖直方向的动力臂的长度：
F1＝(G×L3)÷L1    (1)；
L2>(F1×L4)÷F    (2)；
其中，L1表示第一阻力臂，L2表示动力臂，L3表示重力臂，L4表示第二阻力臂，G表示支撑组件负重，F表示推力，F1表示阻力；
其中，第一阻力臂在第二阻力臂上方。
阻力F1即自第二滑轮与滑轨接触点起垂直于底座3的力，负重G即垂直于第二滑轮接触的滑轨中点的重力，重力臂L3即与第二滑轮接触滑轨的中点至该支撑组件旋转轴的直线距离，阻力臂L1即自第二滑轮与滑轨接触点至该支撑组件旋转轴的直线距离，动力臂L2即自支撑杆与底座3枢轴连接点起至推力F延长线的直线距离。
动力臂L2长度与翻转机构厚度成正比例关系，即动力臂L2长度越短，翻转机构厚度越薄，进而影响床体的厚度。例如，增加第一阻力臂长度、减小重力臂长度，以减小阻力，在减小阻力的情况下，减小第二阻力臂长度，以进一步减小动力臂长度等。在F<3000N、G>1285N时，即床体承受人体重量的情况下，通过受力分析，模拟更改力臂位置，计算受力的变化，找到最佳的力臂，优化床体力臂结构，减少床体的厚度，使其变薄。
进一步地，被所述柔质包覆结构101包覆的所述支撑组件5的宽度大于自身的高度。
支撑件宽度大于自身的高度，可以为柔质包覆结构101提供更强的垂直方向支撑性。
图3为本发明实施例的一种床体结构的俯视示意图，如图3所示，进一步地，所述底座3包括：前框架302和后框架303；其中，所述前框架302和所述后框架303枢轴连接；所述第一支撑组件6和所述第二支撑组件7以所述前框架302和所述后框架303之间的轴心线为转轴相对于所述第三支撑组件8、所述第四支撑组件9和第五支撑组件10可旋转。
第一支撑组件6和第二支撑组件7设置在前框架302的顶部，第三支撑组件8、第四支撑组件9和第五支撑组件10设置在后框架的顶部303， 距前、后框架之间转轴线最近的第二支撑组件7和第三支撑组件8的边沿可无限接近该转轴线，柔质包覆结构101在前框架302和后框架303的交界处也是分开的，以配合前框架302和后框架303枢轴连接以便折叠，对应的支撑组件5可分别跟随前框架302和后框架303折叠。第八支撑件704和第十一支撑件803分别向所述底座3方向延伸，并在延伸段分别增设卡槽102且与其他卡槽102形成两个闭合的卡槽102圈，安装方便、牢固，保证面的平整，使得视觉上接近于一个完整的平面；此时，可以选择两块柔质支撑层4进行安装，两块柔质支撑层4分别覆盖前、后框架顶部的支撑组件5上，再用卡紧件103分别卡入对应的卡槽102进行张紧，降低了对单张柔质支撑层4面积的要求，又可以配合分体式的柔质包覆结构101和底座3进行折叠，这样就可以在工厂直接组成完成，然后折叠运输至目的地，即实现了折叠功能，方便运输、节约成本；又保证柔质支撑层4的完整性和产品的美观性。
优选地，还可在第二十支撑件上增设档杆，防止展开状态下床垫发生位移。
