Description
技术领域
本实用新型涉及床上用品领域,具体涉及一种智能床垫和智能床罩。
背景技术
在现有技术中,常看到使用压电式传感器监测人体活动、呼吸率和心率。但是,压电式传感器有非常高的直流输出阻抗,并可以模拟成一个成比例的电源和滤波网络。输出电压是直接与其作用力、压力或者拉力成比例的。由于压电式传感器材料的作用,输出电压范围相对于拉力/压力会变化。
另一方面,压电式传感器由压电式陶瓷(压电换能器陶瓷)或单晶材料组成,这些材料都是坚硬,如果置入床垫等床上用品,会让人感觉不舒服。而且,这些材料都是随着时间的推移敏感度会下降,而且,温度升高,敏感度下降得更快,从而使得使用压电式传感器的床上用品存在着不可避免的产品缺陷。
压电式传感器的另一个主要缺点是不能应用于真正的静态测量。静力将导致压电式材料上有固定数量的电荷,这就意味着一旦压力或重量达到稳定状态,压电式传感器的输出电压就会消失。因此,当人体处于深度睡眠时,就难以感测到人体状况。
实用新型内容
本实用新型要解决的技术问题在于,针对现有技术的上述缺陷,提供一种智能床垫和智能床罩,克服压电式传感器带来的缺陷,提供一种安全舒适的可监测人体睡眠质量的新型智能床垫和智能床罩。
本实用新型提供的智能床垫,包括床垫本体及柔性光纤感应薄膜。柔性光纤感应薄膜设置于床垫本体上,包括夹层和光纤。夹层包括上层薄膜和下层薄膜,光纤夹在上层薄膜和下层薄膜中间;其中,上层薄膜和下层薄膜上设置有突起物,用于增强人体在柔性光纤感应薄膜上活动造成的光损耗。
本实用新型提供的智能床罩,包括床罩本体及柔性光纤感应薄膜。柔性光纤感应薄膜设置于床罩本体上,包括夹层和光纤。夹层包括上层薄膜和下层薄膜,光纤夹在上层薄膜和下层薄膜中间;其中,上层薄膜和下层薄膜上设置有突起物,用于增强人体在柔性光纤感应薄膜上活动造成的光损耗。
本实用新型的有益效果在于,通过使用柔性光纤感应薄膜上及其上设置的突起物,可以使得智能床垫和智能床罩在保证安全舒适的前提下,还能更灵敏的监测人体的存在、活动、呼吸率和心率。

具体实施方式
图1为智能床垫310的示意图。图2是图1所示的智能床垫310的横截面图,智能床垫310包括床垫本体202和柔性光纤感应薄膜113,柔性光纤感应薄膜113设置于床垫本体202上。床垫本体202是指目前床垫的常用结构主体,包括弹簧床垫、海绵床垫、棕榈床垫、乳胶床垫、水床垫、气床垫、磁床垫等等。柔性光纤感应薄膜113可以嵌入床垫本体202内,或缝制于床垫本体202表面,也可以使用诸如拉链、魔术贴等的连接件与床垫本体202相连,用于感测智能床垫310上人体是否存在、人体在智能床垫310上的活动、呼吸率以及心率。在实际生产中,柔性光纤感应薄膜113可以与床垫本体202做成是分离的,也可以与床垫本体202一体化。
图3为智能床罩311的示意图。床罩是指与床垫一起使用,包裹在床垫外层,用来保护床垫的床上用品,主要是为了拆洗和晾晒方便。需要说明的是,图3仅供示意,在具体实施方式中,床罩不限定于图3所示的形状和结构。在其他实施例中,床罩可以与床垫外形一样,使用时套在床垫外面,或设置在床垫上面,通过拉链等方法与床垫结合在一起使用。
图4是图3所示的智能床罩311的横截面图。智能床罩311包括床罩本体201和柔性光纤感应薄膜113,柔性光纤感应薄膜113嵌入床罩本体201内,或缝制于床罩本体201表面,也可以使用诸如拉链、魔术贴等的连接件与床罩本体201相连。在实际生产中,柔性光纤感应薄膜113可以与床罩本体201做成是分离的,也可以与床罩本体201一体化。为了清洗床罩本体201的方便,柔性光纤感应薄膜113优选分离设计。
图5显示了柔性光纤感应薄膜113的部件分解图,图6显示了夹层114的透视图,图7显示了柔性光纤感应薄膜113的横断面。
柔性光纤感应薄膜113包括夹层114和光纤115。夹层114包含上层薄膜140和下层薄膜141。上层薄膜140和下层薄膜141可以由塑料、橡胶、尼龙或者任何其他柔性材料组成,最优为聚乙烯。
光纤115置入到上层薄膜140和下层薄膜141中间。上层薄膜140和下层薄膜141上设置有突起物142。突起物142会压住光纤115,当人体躺在柔性光纤薄膜113上活动时,光纤115会在突起物142的作用下产生更大的光损耗。突起物142由与上下层薄膜相同的材料组成,例如塑料、橡胶、尼龙或者任何弹性材料,优选聚乙烯。
在一实施例中,突起物142可以是多个线状条,在其他实施方式中,突起物142还可以是矩阵凸点。在突起物142为线状条的实施例中,线状条的方向与光纤115所摆放的主方向垂直。由于光纤115一般是蜿蜒摆放的,在此,光纤115所摆放的主方向是指超过总长度一半以上的光纤115的摆放方向。线状条与光纤115所摆放的主方向垂直,可以确保更多光纤115与线状条能直接接触,以增强光损耗。在突起物142是矩阵凸点的实施例中,矩阵凸点与光纤115所摆放的主方向无关,只需要确保矩阵凸点在一定密度范围内即可。
在一实施例中,突起物142的横截面可以是箭头形状。在其他实施方式中,突起物142的横截面还可以是其他形状,例如梯形、半圆形、矩形等等。具体的,线状条和凸点的横截面皆可采用上述形状。
柔性光纤感应薄膜113的敏感度由三个因素控制,即夹层114的特性、柔性光纤感应薄膜113的配置、光纤115的构成和特性。对于夹层114,图8显示了影响柔性光纤感应薄膜113敏感度的两个参数,即突起物142的高度143和两个临近突起物的距离144(下称宽度)。通过改变这两个参数,可以调整柔性光纤感应薄膜113的敏感度以满足不同敏感度需求的应用。实验显示高度143与宽度144的比率为2/5时会达到最好的敏感度和坚固性。如果高宽比小于2/5,敏感度会下降。这就意味着对于同一个光纤,更短的突起物高度和更宽的突起物间距会引起敏感度的下降。如果高宽比大于2/5,敏感度会更大,但是坚固性会受到影响,因为光纤115由于更大的弯曲角将会承受更大的压力。
上层薄膜140上的突起物142和下层薄膜141上的突起物142是错位排列的,当有人体躺在柔性光纤感应薄膜113上时,由于上下突起物142的错位排列使得整条光纤115在轴向上产生更大的弯曲,进而产生更大的光损耗,从而增强了柔性光纤感应薄膜113的检测灵敏度。而且,这种错位排列也可以避免上层薄膜140上的突起物142和下层薄膜141上的突起物142直接对压到光纤115上,从而避免造成光纤115的破裂。
为了避免光纤115破裂,可在夹层114中增加保护膜125。在不同的实施例中,保护膜125可依据突起物142的方向来设置不同的配置。图9到图11显示了柔性光纤感应薄膜113的不同配置(A、B、C)。对于A或B或C的选择取决于对柔性光纤感应薄膜113敏感度、坚固性的权衡和附加保护膜125的成本。
在配置A中,如图9所示,上层薄膜140上的突起物142是向下的,下层薄膜141上的突起物142是向上的,所以上层薄膜140和下层薄膜141上的突起物142是面对面的。配置A提供柔性光纤薄膜113最好的敏感度。然而,当外部突然的急剧压力作用于柔性光纤感应薄膜113上时,配置A的坚固性最低。为了减少配置A易对光纤115造成破坏,在夹层中嵌入两层保护膜夹住光纤115。保护膜可以由塑料、橡胶、尼龙或者任何其他弹性材料构成,优选的是聚乙烯。
在配置B中,如图10所示,下层薄膜141上的突起物142和上层薄膜140上的突起物142都是向上的。对于配置B,上层薄膜140上的突起物142没有和光纤115接触。在这种情况下,只有一片保护膜125嵌入夹层114中保护光纤115,保护膜125放于光纤115和下层薄膜141之间。
在配置C中,如图11所示,上层薄膜140上的突起物142是向上的,下层薄膜141上的突起物142是向下的,所以上层薄膜140上的突起物142和下层薄膜141上的突起物142是背靠背的,没有任何突起物142是和光纤115相连的。对于配置C,不需要保护膜125保护光纤115。
另一个影响柔性光纤感应薄膜113敏感度的因素是光纤115的特性。选择不同折射率的光纤,柔性光纤感应薄膜113的敏感度是可调的。
智能床垫310和智能床罩311还包括电子盒312,与柔性光纤感应薄膜113相连。图12是本实用新型的智能床垫310连接电子盒312的示意图,在本实施方式中,电子盒312设置于智能床垫310和智能床罩311外部,并通过光纤保护套313与智能床垫310和智能床罩311中的柔性光纤感应薄膜113相连。在其他实施方式中,电子盒312也可以嵌入到智能床垫310的床垫本体中。
图13是本实用新型柔性光纤感应薄膜113与电子盒312连接的框图。电子盒312内设置有SC连接器119、可编程LED驱动110、光源111、光传感器112和处理器116。可编程LED驱动110的输出端与光源111连接,光源111与光纤115的一端连接,光纤115的另一端与光传感器112连接。处理器116传输控制信号给可编程LED驱动110产生LED电流给光源111。光源111在LED电流驱动下产生光并通过SC连接器119进入光纤115中。光传感器112用于检测光纤115中的光损耗信号。处理器116处理由光传感器112获取的光损耗信号用以监测人体的存在、活动、呼吸率和心率。
电子盒312还包括无线模块117。无线模块117是可选的且与处理器116相连,作用是将处理器116得出的信号状态传输给智能手机、平板电脑等远程显示设备,智能手机、平板电脑等远程显示设备处理并显示处理器116传输的信号状态。
在具体实施例中,电子盒312可通过电源适配器314与墙上的交流电源相连完成供电,也可以在内部设置电池来完成供电。
在智能床罩311的实际应用中,需要保护柔性光纤感应薄膜113中的光纤115由于弯曲导致的破坏。为了实现上述保护,可在智能床罩311内的柔性光纤感应薄膜113下面设置保护层122。保护层122用于限制光纤115的弯曲度在它的承受规格之内以防损坏。
图14是本实用新型中一实施例中保护层122的示意图。图15是一实施例中增加了保护层122的智能床罩311的横断面的示意图。图16是图15所示的智能床罩311弯曲时的横断面示意图。如图14所示,保护层122包括多个161所示宽度、162所示长度的条状物,并以164所示的间距连接在一起,延伸至柔性光纤感应薄膜113的长和宽。当智能床罩311弯曲或折叠时,164所示的间距和163所示的厚度控制光纤115的弯曲角度160在其承受极限内。保护层122的另一个作用是协助智能床罩311卷起。更优的,可在柔性光纤感应薄膜113上部设置泡棉层123。当人体躺在上面时,泡棉层123可以使智能床罩311更舒适。智能床罩311还可以包括外层防水套面124用于保护柔性光纤感应薄膜113、泡棉层123和保护层122。
应当理解的是,以上实施例仅用以说明本实用新型的技术方案,而非对其限制,对本领域技术人员来说,可以对上述实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而所有这些修改和替换,都应属于本实用新型所附权利要求的保护范围。
