Description

蜂窝结构座垫
技术领域
本发明涉及一种蜂窝结构座垫，更具体地，涉及一种能够提供就座时的稳定感和舒适感的同时具有增强的热稳定性的蜂窝结构座垫。
背景技术
一般来说，垫子被设计成放置在地板或椅子上并供使用者就坐，大多是指用棉花填充的棉垫。
棉垫通过吸收冲击而为坐在其上的使用者提供了柔软的就坐感。提供就坐感的原因是：棉垫中的纤维形成为网状结构，并且连续供给的空气提供了恢复力。然而，为了提高就坐感，需要多达足以确保就坐感的棉花。此外，棉垫的长时间使用导致垫子的厚度减小，使得就坐感和透气性下降。
这种棉垫不具有防滑功能。因此，当坐在垫子上的使用者有移动时，垫子随着使用者的移动而滑动，而不在适当位置。
为了减少棉垫的局限性，近来已经提出由具有弹性和摩擦力的材料(例如橡胶、聚乙烯等)形成的凝胶型垫子，从而提供缓冲感并减少滑动。
然而，通常由硬橡胶材料形成的传统凝胶型衬垫不能为坐在其上的使用者提供舒适的就坐感，并且与棉垫相比具有重的重量。
发明内容
【技术问题】
本发明为了解决上述问题而作出，本发明提供了一种蜂窝结构座垫，其中通过具有优异的透气性的通风结构而使得空气在垫子中顺畅地移动，从而能够有效地排出水分和汗液，因此实现了热稳定性，并且将身体压力均匀地分布以减轻施加到特定身体部位的应变，从而能够改善就坐感。
【技术方案】
本发明的一个方面提供一种由具有凝胶状流动性和弹性的韧性树脂或韧性橡胶材料形成的蜂窝结构座垫，所述蜂窝结构座垫包括：下片体，其具有正六边形横截面并且沿上下方向穿孔的第一通孔，所述第一通孔沿x轴方向和y轴方向重复地形成，同时由第一间隔件以预定间隔被彼此间隔开；以及上片体，其形成下片体上并且包括具有比第一通孔的正六边形横截面大的正六边形横截面并且沿上下方向穿孔的第二通孔，所述第二通孔沿x轴方向和y轴方向重复地形成，同时由具有小于第一间隔件的厚度(T1)的厚度(T2)的第二间隔件以预定间隔被彼此间隔开，其中，第一通孔和第一间隔件的中心分别与第二通孔和第二间隔件的中心对准。
下片体和上片体可以均具有正方形形状，并且在下片体和上片体的侧面形成有侧壁。
上片体和/或下片体在其一侧的端部处的厚度可以逐渐减小，以形成以直线或曲线形式向下倾斜的倾斜面。
在下片体和/或上片体中，在第一通孔或第二通孔处可以形成有加强肋，所述加强肋的端部与第一间隔件和/或第二间隔件连接。
【有益效果】
从上述可以看出，根据本发明，通过具有优异的透气性的通风结构而使得空气在垫子中顺畅地移动，从而有效地排出水分和汗液，因此能够实现热稳定性，并且将身体压力均匀地分布以减轻施加到特定身体部位的应变，从而能够改善就坐感。
此外，通过反映大腿部分的区域的身体结构来减轻施加到正在就座的使用者的大腿的局部应力，从而能够将不舒服的感觉最小化，并且形成附加的肋，从而能够增强结构稳定性可以并且可以使注射工艺中的缺陷率最小化。

图4是沿图2的B-B'线截取的横截面图。
具体实施方式
根据本发明的蜂窝结构座垫提供了就座时的稳定感和舒适感，并且确保了增强的热稳定性。在图1至图4中示出了本发明的示例性实施例。
图1是示出根据本发明的示例性实施例的蜂窝结构座垫的立体图，图2是示出根据本发明的示例性实施例的蜂窝结构座垫的平面图，图3是沿图2的A-A'线截取的横截面图，图4是沿图2的B-B'线截取的横截面图。
根据本发明的示例性实施例的蜂窝结构座垫由具有凝胶状流动性和弹性的韧性树脂或韧性橡胶材料形成以提供缓冲感，并且包括：下片体120，其包括具有正六边形横截面并沿上下方向穿孔的第一通孔121，第一通孔121沿x轴方向和y轴方向重复地形成，同时由第一间隔件122以预定间隔被彼此间隔开；和上片体110，其形成在下片体120上并且包括具有比第一通孔121的正六边形横截面大的正六边形横截面并沿上下方向穿孔的第二通孔111，第二通孔111沿x轴方向和y轴方向重复地形成，同时由具有厚度T2(小于第一间隔件122的厚度T1)的第二间隔件112以预定间隔被彼此间隔开。
在这种情况下，第一通孔121和第一间隔件122的中心分别与第二通孔111和第二间隔件112的中心对准。
如上所述，下片体120和上片体110彼此一体地结合，并且具有其中沿其厚度方向布置的多个正六边形通孔121、111的蜂窝结构，其中，上片体110的第二通孔111比下片体120的第一通孔121大，使得下片体120的第一间隔件122比上片体110的第二间隔件112大。如下片体120和上片体110的横截面所示，由于第一间隔件122和第二间隔件112之间的厚度差，形成有台阶113。
若没有第一间隔件122和第二间隔件112之间的厚度差异，可能发生弯曲，使得间隔件可能过度偏转并彼此接触，最终劣化就坐压力的分布。然而，如本发明，当第一间隔件122形成为具有比第二间隔件112的厚度大的厚度时，与车辆片材等接触的第一间隔件122最终具有较大的厚度，从而具有最小化的变形并且提供稳定的支撑，并且与坐在垫子上的使用者的臀部和大腿接触的第二间隔件112形成为具有相对较小的厚度，从而提供柔软的就坐感。
如下面的表1所示，本发明的有益效果可以通过对示例性实施例和比较例之间的最大压力、有效孔数和平均压力的比较结果来证实，其中在示例性实施例中，第一间隔件122的厚度T1为2.0mm，第二间隔件112的厚度T2为1.5mm，第二通孔111的一侧的长度D为6.7mm；在比较例中，将第一间隔件122和第二间隔件112的厚度T1、T2设置为不同。结果见表2。
【表1】
类别 T1(mm) T2(mm) D(mm) 体积(cc) 重量(g) 比率(％)
示例性实施例 2.0 1.5 6.7 410 357 -
第一比较例 1.75 1.75 6.7 401 349 -2.2
第二比较例 2.2 1.7 6.7 452 393 10.2
第三比较例 1.8 1.3 6.7 367 319 -10.5
作为参考，根据分析表2中列出的上述示例性实施例和各种比较例中的最大压力、有效孔数和平均压力的方法，每个传感器单元的压力值通过构建独立的程序并使用作用在压头的接触表面上的反作用力而获得。在这种情况下，通过将每个传感器单元中存在的节点的所有反作用力除以单元面积来计算压力。传感器单元的尺寸为15mm×15mm。由于压力分布可能根据传感器单元和产品之间的对准而有所不同，所以进一步对沿横向方向和纵向方向有7.5mm位移的情况计算压力，并且基于压力平均值获得最大接触压力。应用第一阶Mooney-Rivlin超弹性材料模型进行分析。
【表2】
参考表2，当与第一间隔件122和第二间隔件112的厚度T1和T2彼此相同的第一比较例进行比较时，示例性实施例和第三比较例(其中第一间隔件122的厚度T1大于第二间隔件112的厚度T2)具有较低的最大压力和较大的有效孔数。
第三比较例具有最低的最大压力和最大的有效孔数，但是第二间隔件112的厚度过小，为1.3mm，因此第三比较例难以批量生产。
作为参考，下面将描述的下片体120、上片体110和侧壁130可以由选自由丁基橡胶、硅橡胶、丙烯酸橡胶、氢化丁腈橡胶(NBR)、表氯醇橡胶、氯磺化聚乙烯橡胶、氯化聚乙烯橡胶和丙烯酸丁酯-丙烯酸乙酯-丙烯腈橡胶所组成的组中的韧性橡胶材料；果冻状材料或软树脂形成。此外，下片体120、上片体110和侧壁130可以由各种已知的天然材料或合成材料形成。
根据另一示例性实施例，下片体120和上片体110各自具有正方形形状，并且侧壁130形成在下片体120和上片体110暴露于外部的侧面。
侧壁130与下片体120和上片体110的端面接触。侧壁130用于将下片体120与上片体110连接，以增加下片体120和上片体110的结合力，并且用作用于增加下片体120和上片体110的耐久性框架。下片体120、上片体110、侧壁130和加强肋150(将在下面描述)可以分别形成后联接，或者可以在单个工艺(例如注射成型)中一体地制造。
根据本发明的另一个示例性实施例，上片体110和/或下片体120在其一侧的端部处厚度逐渐减小，以形成倾斜的表面140，倾斜表面140以直线或曲线的形式向下倾斜。
倾斜表面140设置在与坐在座垫上的使用者的大腿接触的部分。倾斜表面140向下倾斜指向垫子的前方，去除了引起就座的使用者的大腿部分被按压的矩形边缘，使得施加到就座的使用者的大腿的局部应变被去除，因此提高了就座时的稳定感。
当倾斜表面140如此形成时，侧壁130在设置在就座的使用者的臀部部分的后侧和设置在就座的使用者的大腿部分的前侧之间的厚度可以不同。具体地说，前侧的侧壁130的厚度小于后侧的侧壁130的厚度。
根据本发明的另一示例性实施例，下片体120和/或上片体110在第一通孔121和/或第二通孔111处设置有加强肋150，该加强肋150的端部连接到第一间隔件122和/或第二间隔件112。
加强肋150可以设置成包括直线形或十字形的各种形状。加强肋150的每个端部连接到第一间隔件122和/或第二间隔件112。当加强肋150如此形成时，第一间隔件122和/或第二间隔件112可以由于沿水平方向形成的加强肋150的作用而沿水平方向被支撑，从而可以提高垫子的耐久性，并且可以在注射成型时除去毛刺，并且可能降低由于毛刺引起的缺陷率。
如上所述，根据本发明，通过具有优异的透气性的通风结构而使得空气在垫子中顺畅地移动，从而能够有效地排出水分和汗液，因此能够实现热稳定性，并且将身体压力均匀地分布以减轻施加到特定身体部位的应变，从而能够改善就坐感。此外，通过体现大腿部分的区域的身体结构来减轻施加到正在就座的使用者的大腿的局部应力，从而能够将不舒服的感觉最小化，并且形成附加的肋，从而能够增强结构稳定性可以并且可以使注射工艺中的缺陷率最小化。
虽然为了说明的目的已描述了本发明的示例性实施例，但是本领域技术人员应当理解，在不脱离本发明的范围和精神下，可以进行各种修改、改变和替换。
因此，本发明的范围由所附权利要求限定。
