如图1至图44所示，面板结构100被广泛应用于桌椅板凳、墙壁、柜体、托盘、货架等设施中，其一般为吹塑结构，采用热塑性塑料制成，适用于吹塑的塑料有聚乙烯、聚氯乙烯、聚丙烯、聚酯、苯乙烯聚合物等。面板结构100也可以通过注塑工艺加上气辅技术成型。
面板结构100包括周壁，周壁内形成一个中空腔101。片状或板状的面板结构100具有第一表层10、第二表层20和环形的外周壁102，至少部分第二表层20与第一表层10之间形成中空腔101。在一些简单的成型工艺中，第一表层10和第二表层20之间仅设置有一个大的中空腔101。相对的，在一些较复杂的成型工艺中，第一表层10和第二表层20之间也可以设置有多个相互连通或独立的中小型的中空腔101；这种情况下，第一表层10和第二表层20之间相互连接以分隔两个相邻的中空腔101。
将第一表层10朝向第二表层20的侧面记为第一内表面12，背离第二表层20的侧面记为第一外表面11；将第二表层20朝向第一表层10的侧面记为第二内表面22，背离第一表层10的侧面记为第二外表面21。根据面板结构100的使用场景，例如作为桌面或凳面时，第一外表面11和第一内表面12可以设置为平面，第二内表面22及第二外表面21可以为曲面。
为了增加面板结构的机械强度，通常在面板结构上形成大小均匀且排布规律的凹陷。例如，面板结构为多边形桌面，其第一表层为较为平整的平板，第二表层上设置有多个凹陷，这些凹陷大小、形状一致，并且多个凹陷呈多边形阵列，以使得多边形桌面的各个方向具有相对统一的强度。
然而，即使在受力相同的情况下，多边形桌面各处的形变量也是不同的；并且在实际使用过程中，多边形桌面各处的受力经常是不均衡的；因此，将多边形桌面设置成统一的强度无法使其受力最大化。
众所周知，多边形桌面的支撑腿223一般在靠近边角的位置，若多边形桌面具有相对统一的强度，那么在使用过程中，多边形桌面的中部更容易发生形变。并且在许多使用场景中，为了防止多边形桌面倾翻，人们更倾向于把物品放在桌面中部的位置，也会造成桌面中部更容易发生形变。此外，桌面与支撑腿的接触部分强度较高，远离支撑腿的部分强度较低，但支撑腿与桌面的接触部分压强较大，容易对桌面造成永久性损害。
再如，当面板结构100作为体育场观众席的凳面时，人们也更倾向于坐在凳面的中间而非两边，若凳面具有相对统一的强度，那么凳面中间更容易发生更大的形变。又如，当面板结构100作为托盘时，人们也更倾向于将物品放在托盘中部而非托盘边缘，若托盘具有相对统一的强度，那么托盘中部容易发生更大的形变；但若托盘长时间运输同一种物品，并且该物品与托盘相接触的不同位置具有不同的压强，那显然，压强大的位置更容易发生更大的形变。
基于此，本申请以多边形桌面或多边形凳面为例，提出面板结构100及其设计方法。可以理解，面板结构100不仅限于桌面或凳面，也可以作为其他产品使用，例如托盘、货架、支撑板等，在此不做限定。当然，面板结构100的形状也可以多种多样，例如为圆形、圆弧与多边形结合等，并不局限于多边形。
面板结构100的设计方法包括以下步骤：分析面板结构100的惯用场景受力特点；根据惯用场景受 力特点，在受力较大的区域布局机械强度较高的加强单元30，在受力较小的区域布局机械强度较低的加强单元30。其中，至少部分加强单元30不规律地分布。
需要特别说明的是，“不规律地分布”是指，这些加强单元30不是以某一点为中心中心对称设置，或以某一线为中心轴对称设置，或通过阵列(例如圆形阵列、多边形阵列、扇形阵列、椭圆形阵列等)的方式规则排布。
还需要特别说明的是，这些加强单元30中，可以有规则的形状，例如圆形、椭圆形、正多边形、扇形等，也可以有相同的形状，但这些形状规则和形状相同的加强单元30不是规律地分布。当然，这些加强单元30中也可以有不规则的形状(非圆形、椭圆形、正多边形、扇形等规则形状)，例如非长方形、非平行四边形的四边形，非直角三角形、等腰三角形的三角形等；这些加强单元30也可以是多个规则形状相结合的形状，例如四边形与扇形相结合的形状等。
可以理解，机械强度是指单位面积上所能承受的最大负荷，对于桌面、凳面、货架、托盘等面板结构100，可以通过抗弯强度、抗压强度、抗折强度或最大承重质量等表示。
请参阅图2、图14、图27及图44，面板结构100还包括至少一个加强单元30，至少一个加强单元30均与第二表层20一体成型，且加强单元30中至少部分朝向第一表层10凹陷；其中，至少部分加强单元30在第二表层20上不规律地分布。传统技术的面板结构100中加强单元30形状相同且分布规律，如果加强单元30在某一个方向承力较差，那么至少一个加强单元30叠加，很容易在该方向上形成受力短板。当第二表层20上有至少部分加强单元30是不规律分布时，不规律分布的加强单元30能够避免面板结构100在某一方向上存在受力短板。此外，将加强单元30设置成不规律分布，还可以根据面板结构100的使用场景、惯常受力等因素设计加强单元30的形状、大小、凹陷高度、分布方式等，能够根据其惯用使用场景优化加强单元30的布局。
需要说明的是，以其中一个加强单元30为例，该加强单元30中至少部分朝向第一表层10凹陷，该加强单元30中也可以存在背离第一表层10外凸的部分，加强单元30可以是在内凹形成的壁面上再外凸，也可以是在外凸形成的壁面上再内凹，在此不做限定。
如图18、图19、图31、图44所示，一些加强单元30包括第一凹陷部31，第一凹陷部31朝向第一表层10凹陷，每个第一凹陷部31均具有侧壁31a及底壁31b，将第一表层10朝向第二表层20的侧面记为第一内表面12，一些第一凹陷部31的底壁31b与第一内表面12相接合。
可以理解，多种加强单元30可以出现在同一个面板结构100中，上述加强单元30可以和其他实施例中的加强单元30设在同一个第二表层20。
如图8、图9所示，一些加强单元30包括第一凹陷部31，第一凹陷部31朝向第一表层10凹陷，每个第一凹陷部31均具有侧壁31a及底壁31b，将第一表层10朝向第二表层20的侧面记为第一内表面12，一些第一凹陷部31的底壁31b与第一内表面12相之间具有间隔。
如图8、图9、图18、图19、图31、图44所示，一些加强单元30包括第二凹陷部32，第二凹陷部32设置在第一凹陷部31的底壁31b，第二凹陷部32朝向第一表层10凹陷，每个第二凹陷部32也均具有侧壁32a及底壁32b；一些第二凹陷部32的底壁32b与第一内表面12相之间具有间隔，或者，一些第二凹陷部32的底壁32b与第一内表面12相之间相接合。
通过第二表层20的凹凸变化可以调整面板结构100的机械强度。比如，设置有第一凹陷部31和第二凹陷部32的加强单元30的机械强度，高于仅设置有第一凹陷部31的加强单元30的机械强度。在一定程度上，凹凸变化的次数越多，面板结构100的机械强度越大。当然，也可以通过第一表层10的凹凸变化调整面板结构100的机械强度，还可以通过加强单元30的疏密程度调整面板结构100的机械强度。
可选的，第一凹陷部31为多边形状，第二凹陷部32为至少一个，至少一个第二凹陷部32分别分布在第一凹陷部31的顶角处或棱边处。第二凹陷部32为圆点形、多边形或扇形。可选的，多边形状的两个相邻的边之间选用圆角过渡，以便于成型。当然，第一凹陷部31也可以选用圆形、扇形、椭圆形或多种基础形状组合的形状，还可以是长条形；当第二凹陷部32的面积较大时，可以选用多边形、圆形、椭圆形、扇形或多种基础形状组合的形状；当第二凹陷部32的面积较小时，可以选用圆点等形状。
如图8、图9、图18、图19、图31、图44所示，一些加强单元30还包括凸起部33，凸起部33 设置在第一凹陷部31的底壁31b，凸起部33向背离第一表层10的方向外凸，从而增加第二表层20的凹凸变化，以提高面板结构100的机械强度。
可以理解，加强单元30可以不止包括第一凹陷部31、第二凹陷部32和一个凸起部33，还可以设置更多个凹陷和更多个凸起，并将这些凹陷和凸起排列组合、设计布局，以增加面板结构100的机械强度。当然，第二凹陷部32可以与第一凹陷部31大致为相似图形，其形状也可以区别于第一凹陷部31。
可选的，至少一个第二凹陷部32分布在凸起部33的外周。第一凹陷部31为多边形，第二凹陷部32的个数与第一凹陷部31的拐角数量相同，第二凹陷部32分别位于第一凹陷部31的拐角处。当然，第二凹陷部32还可以集中分布在凸起部33的一侧，也可以均匀分布在凸起部33的外周。
可选的，凸起部33的凸起形状与第一凹陷部31的凹陷形状大致为相似图形。可以理解，在其他实施例中，凸起部33的形状也可以区别于第一凹陷部31，在此不做限定。
可选的，将第二表层20相对背离第一表层10的侧面记为第二外表面21，加强单元30上的凸起部33向外凸起的高度不高于该加强单元30周边的第二外表面21。
中空腔101最大高度不小于8mm，第一凹陷部31的面积占比不小于第二表层20的50％，第二凹陷部32的高度不高于5mm。这样的参数更有利于面板结构100的成型。
如上，桌面、凳面、托盘等在许多使用场景中，中部是最容易发生形变的位置。那么，在一些实施例中，相比于位于第二表层20边缘的加强单元30，可以将位于第二表层20中部的加强单元30设置的更加密集及/或凹凸变化更多，以增加面板结构100中部的机械强度。
当然，也可以通过设置强化件50的方式增加面板结构100的机械强度。强化件50的设置位置也可以根据面板结构100的惯用使用场景进行精心设计。例如，强化件50可以固设在第一表层10、第二表层20、面板结构100的环形周壁中的至少一者上。上位元件强化件50可以是金属贴片。
还可以通过设置支撑组件200的方式增加面板结构100的机械强度。可以通过调节支撑组件200的设置位置、支撑面的形状及大小、支撑组件200的材质等方式，来设计匹配面板结构100的惯用使用场景。
由于设置了强化件50/支撑组件200的位置机械强度较高，其周边的凹凸结构也可以进行相应的改变。例如，相比于靠近强化件50/支撑组件200的区域，远离强化件50的区域加强单元30更加密集及/或凹凸变化更多，以增加面板结构100相对远离强化件50/支撑组件200的区域的机械强度。
可以理解，面板结构100具有多种方式能够改变其机械强度，比如通过加强单元30的密集程度、同一个加强单元30上凹凸变化的次数(即设置凹陷或凸起的个数)、第一凹陷部31或第二凹陷部32或凸起部33的凹凸变化尺寸(即凹陷或凸起的高度及面积)、强化件50的设置与否、加强肋40的设置与否、第一表层10与第二表层20之间的间距等等，这些方式可以排列组合任意设计，以适配于不同面板结构100的使用场景，优化面板结构100的机械强度和制作成本之间的平衡性，使得面板结构100能够适应个性化的使用场景。
本申请还提供了另一种面板结构100及其设计方法，面板结构100中，第一内表面12与第二内表面22中的至少一者为曲面，如图40至图44所示。
面板结构100的设计方法包括以下步骤：分析面板结构100的惯用场景受力特点；根据惯用场景受力特点改变第一内表面12与第二内表面22之间的间距，其中，受力越大的区域第一内表面12与第二内表面22之间的间距越小；第一内表面12与第二内表面22中的至少一者为曲面。通过改变第一内表面12和第二内表面22之间的间距，使面板结构100不同的区域具有不同的机械强度，同样的，可以根据面板结构100的使用场景、惯常受力等因素设计第一内表面12与第二内表面22之间的间距，使得面板结构100能够适应个性化的使用场景。
可选的，第一内表面12与第二内表面22中的至少一者中的至少部分区域为不规律变化的曲面，以更适应个性化需求。
其中，“不规律变化的曲面”是指，该曲面不是规则曲面(当动线按照一定的规律运动时，形成的曲面称为规则曲面)。
基于前述同样的理由，相比于位于第二表层20的边缘，位于第二表层20中部的第二内表面22更加靠近第一表层10，以增加面板结构100中部的机械强度。
可以理解，曲面变化也可以看成一种凹凸变化，曲面变化与加强肋40、强化件50以及加强单元30之间的设置并不冲突，这些方式可以排列组合任意设计，以适配于不同面板结构100的使用场景，优化面板结构100的机械强度和制作成本之间的平衡性，使得面板结构100能够适应个性化的使用场景。
可选的，第二内表面22为曲面，第一内表面12为平面。当然，为了便于成型，可将第一表层10整体设置成平板状，第二表层20整体设置成曲面状。
将第二内表面22最靠近第一内表面12的位置记为波峰H1，将第二内表面22最远离第一内表面12的位置记为波谷H2，面板结构100为高密度聚乙烯，其密度为ρ，面板结构100的承重为G；其中，G*ρ*(H2/H1)＞141.15。
可选的，当面板结构100为桌面时，第一表层10及第二表层20的壁厚均为约2mm，波峰H1约为6mm，波谷H2约为8mm，密度为ρ为0.941g/cm 3至0.96g/cm 3，承重G≥150kg；当面板结构100为凳面时，第一表层10及第二表层20的壁厚均为约1.8mm，波峰H1约为4.4mm，波谷H2为6.4mm，密度为ρ为0.941g/cm 3至0.96g/cm 3，承重G≥220kg。
曲面在面板结构100厚度上的变化不超过3mm，以配合吹塑工艺。
可以理解，第一内表面12及/或第二内表面22是曲面不影响加强单元30的设置，加强单元30同样可以设置在第二表层20上，加强单元30的结构特征与上述相同，在此不作赘述。
本申请还保护一种具有支撑组件200的面板结构100，支撑组件200连接于面板结构100，并用于支撑面板结构100。
请参阅图2、图14、图27、图40，面板结构100还包括加强肋40，加强肋40也用于增加第二表层20的凹凸变化，加强肋40与第二表层20及加强单元30一体成型，且加强肋40向背离第一表层10的方向外凸。
一些加强单元30位于加强肋40上；一些加强单元30位于第二表层20未设置加强肋40的位置；还有一些加强单元30，其第一凹陷部31的部分结构位于加强肋40上，另一部分位于第二表层20未设置加强肋40的位置。可以理解，加强单元30的位置可以根据需要进行设计和选择。
在一些情况下，面板结构100需要配合其他外部元件进行使用。例如，当面板结构100作为桌面时，需要设置支撑组件200作为桌腿；当面板结构100作为凳面时，需要设置支撑组件200作为凳腿；当面板结构100作为货架置物板时，需要支撑组件200作为货架支架；当面板结构100作为托盘时，需要支撑组件200作为支脚等等。
如图2所示，加强肋40上开设有卡接槽41，卡接槽41用于卡接支撑组件200，以便于面板结构100与支撑组件200可拆卸连接。可以理解，支撑组件200的设置有利于提高面板结构100的机械强度，并且卡接槽41的设置也增加了第二表层20的凹凸变化，也有利于提高面板结构100的机械强度。此外，卡接槽41也可以开设在第二表层20的其他位置，并不是必须要设置在加强肋40上。
卡接槽41可以为多个，以供支撑组件200以不同姿态支撑面板结构100。如图8所示，可选的，卡接槽41的底壁41b与第一表层10相连接，以提高卡接槽41位置的稳定性。
下面以桌腿及凳腿为例，对支撑组件200展开详细的描述。
如图10至图12所示，在一个实施例中，支撑组件200支撑在面板结构100的中部。支撑组件200包括两个铰接的支撑件210，每个支撑件210包括一个卡接杆211、两个支撑杆212以及一个落地杆213，两个支撑杆212长度相同，且两个支撑杆212相互铰接并形成X形，每个支撑杆212的两端分别固连于卡接杆211和落地杆213，卡接杆211可拆卸地卡接于卡接槽41中，落地杆213用于与地面接触。卡接槽41也设置为两组，每组中有至少两个卡接槽41，以供支撑组件200以不同的姿态支撑面板结构100。可选的，支撑组件200能够从卡接槽41中脱出，并折叠收纳。
如图20至图25所示，支撑组件200包括支撑框架220及多个支撑腿223，支撑框架220连接于面板结构100的外周壁102及/或第二表层20，多个支撑腿223可转动地连接于支撑框架220；支撑腿223能够转动收拢至贴合第二表层20以形成收纳状态。
可选的，支撑组件200还包括多个铰接杆224，支撑框架220包括至少一个固定杆221和至少一个转动杆222，固定杆221固定连接于面板结构100环形的外周壁102及/或第二表层20，转动杆222的两端分别可转动地连接于两个不同的固定杆221；固定杆221和连接杆围设形成环形的支撑框架220； 多个支撑腿223分别固定连接于转动杆222，且分别通过铰接杆224铰接于转动杆222。
在一个实施例中，支撑组件200支撑在面板结构100的周部。支撑组件200包括支撑框架220、四个支撑腿223以及四组铰接杆224，支撑框架220包括两个固定杆221和两个转动杆222，固定杆221固定连接于面板结构100环形的外周壁102及/或第二表层20，转动杆222的两端分别可转动地连接于两个不同的固定杆221。固定杆221和连接杆围设形成环形的支撑框架220，且固定杆221和连接杆均位于第二表层20的第二外表面21相对靠近周边的周部。四个支撑腿223分别固定连接于转动杆222，且分别通过四组铰接杆224铰接于转动杆222。可选的，四个支撑腿223分别设置在面板结构100的四个边角处。四个支撑腿223能够通过铰接杆224收拢至大致贴合第二外表面21，以形成收纳状态；也能够通过铰接杆224转动至与面板结构100的第一外表面11相垂直，以形成支撑状态。
可以理解，在一些实施例中，支撑框架220的形状与面板结构100的形状为相似图形，例如，当面板结构100为长方形桌子时，支撑框架220也是长方形。四个支撑腿223也可以分为两两分组，同一组中的两个支撑腿223相互连接，且每组支撑腿223通过一组铰接杆224铰接于支撑框架220。如图33至图37所示。
可选的，支撑框架220通过螺纹紧固件225安装于面板结构100环形的外周壁102或第二表层20。
可选的，支撑组件200还包括两个加长片226，其中一个转动杆222的两端分别通过两个加长片226固定连接于两个固定杆221，从而避免收纳状态下的多个支撑腿223之间的位置干扰。
可选的，支撑组件200还包括加强杆227，加强杆227的两端分别固设于同一侧的支撑腿223上，以增加支撑状态下的使用稳定性。
可选的，支撑腿223之间错位设置，以减小收纳厚度。
可选的，支撑组件200还包括捆绑件228，在收纳状态下，捆绑件228能够将支撑腿223与固定件捆绑在一起。

使用过程为，先将凳子400收纳好，放至桌子300的第二表层20，然后将桌子300收纳折叠，使凳子400容纳在容置腔中。可选的，采用捆绑件228将桌子300固定在收纳状态。这样凳子400和桌子300可以形成一体式收纳结构，并且需要使用时，桌子300和凳子400可以分开使用。
可选的，凳子400的支撑腿223向外弯曲，当桌子300和凳子400收纳在一起时，凳子400的支撑腿223与桌子300的支撑腿223处于同一平面。这样，能够提高凳子400在支撑状态下的使用稳定性，并且，当桌子300和凳子400收纳在一起时，支撑腿223一侧能够更加平稳的放置在平面上。
可选的，一张桌子300可以同时与多个凳子400收纳在一起。如图38至图39所示，一张桌子300可以与两个凳子400收纳在一起。
