Description

隐藏式体重测量仪 技术领域
本发明涉及一种称重装置，更具体地说，它涉及一种隐藏式体重测量仪。
背景技术
随着社会的不断发展，人们的生活水平不断提高，人们对于自身的健康情况越来越重视。体重是反映日常饮食摄入量是否达标的重要指标，当一个人的体重过低时，代表这个人日常饮食摄入量过低，其能量摄入未能满足自身的能量消耗；当一个人的体重过高时，代表这个人日常饮食摄入量过高，其能量摄入超出自身的能量消耗。并且，当一个人的体重在短时间内发生明显变化时，很有可能是这个人患有疾病的表现，因此，体重是衡量人们健康状况的重要参数。
目前，人们在测量体重时，通常是使用专门的电子体重秤或机械体重秤测量待测量对象的体重。例如申请号为201620835584.9的中国专利公开了一种新型体重秤，包括：测量踏板及体重测量线路，测量踏板的一面为承载测量面，其中，测量踏板的另一面开设体重测量线路放置凹槽，底部盖板与凹槽的形状及槽体深度相应，将体重测量线路扣合固定于凹槽内部，扣合后与测量踏板的底部平齐。
这种体重秤的测量踏板设置显示屏用于显示称重结果，这就会出现显示屏部件的外观与测量踏板表现不同，从而在结构上体现出一种仪器的视觉效果，出现产品外观与放置的环境不搭的情况，还具有改进的空间。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种隐藏式体重测量 仪，具有易于环境搭配的优点。
为实现上述目的，本发明提供了如下技术方案：
一种隐藏式体重测量仪，包括称重平台，所述称重平台的底侧开设容置腔，所述容置腔的内壁开设若干向称重平台顶侧透光的盲孔，所述容置腔内还设置透过盲孔向称重平台顶侧显示称重结果的显示装置，
所述称重平台的底侧还设置用于输出与承重大小相对应测量信号的称重传感器，所述称重传感器电性连接基于测量信号计算称重结果的处理器模块，所述处理器模块电性连接驱动显示装置显示预设时长称重结果的驱动电路。
采用上述技术方案，在称重平台底侧开设容置腔，用于容纳电子部件，并且在容置腔的内壁设置盲孔，显示装置设置在盲孔内，透过盲孔向称重平台的顶侧显示称重结果，从而将其他例如显示装置等部件隐藏在称重平台内，并且在显示装置不显示时，产品整体呈现为一个平台，易于搭配环境。在称重时，通过称重传感器获取称重重量，之后处理器模块计算沉重结果，并由驱动电路驱动显示装置显示，使用方便。
进一步，所述显示装置包括若干设置于电路板并向盲孔内延伸的发光LED。
进一步，所述盲孔围成若干日字型显示图案。
采用上述技术方案，通过LED透过盲孔发光，进而组成不同的显示数字来显示称重结果，节省成本。
进一步，所述称重传感器的数量为4，分别设置于称重平台的边角。
采用上述技术方案，通过多个称重传感器组成称重桥来测量重量，测量较为精准，并且将称重传感器设置于边角，增大测量的力臂，进一步增强测量的准确性。
进一步，所述称重传感器电性连接有用于给称重传感器提供稳定电压的稳压电路。
采用上述技术方案，通过稳压电路给称重传感器提供稳定电压，避免电压不准确给测量带来误差。
进一步，所述盲孔的内壁设置荧光块，所述荧光块外围套设光致变色罩，所述光致变色罩在受到显示装置标准时长的光照后变为透明，其中标准时长小于预设时长。
采用上述技术方案，在现实装置显示称重结果时，若显示的时长达到标准时长，此时光致变色罩将会由不透明变为透明，光亮将会照射至荧光块上，荧光块吸收光照，而在显示装置的显示时长达到预设时长停止显示后，此时荧光块开始发光，进而让称重结果的显示时间变长，具有节能的效果。
进一步，所述盲孔的内壁涂覆反光涂层。
采用上述技术方案，在盲孔内壁涂覆反光涂层，提升显示亮度，增强光的利用率。
进一步，所述处理器模块包括CSU18M芯片。

综上所述，本发明具有以下有益效果：
1.在称重平台底侧开设容置腔，用于容纳电子部件，并且在容置腔的内壁设置盲孔，显示装置设置在盲孔内，透过盲孔向称重平台的顶侧显示称重结果，从而将其他例如显示装置等部件隐藏在称重平台内，并且在显示装置不显示时，产品整体呈现为一个平台，易于搭配环境；
2.在现实装置显示称重结果时，若显示的时长达到标准时长，此时光致 变色罩将会由不透明变为透明，光亮将会照射至荧光块上，荧光块吸收光照，而在显示装置的显示时长达到预设时长停止显示后，此时荧光块开始发光，进而让称重结果的显示时间变长，具有节能的效果。

具体实施方式
下面结合附图及实施例，对本发明进行详细描述。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
一种隐藏式体重测量仪，参照图1、图2及图3，包括称重平台1，称重平台1的底侧开设容置腔2，用于放置容纳电子元件的电器盒11，电器盒11的背部设置后盖12。
参照图3，容置腔2的内壁开设若干向称重平台1顶侧透光的盲孔3，本实施例中，称重平台1采用为竹板，在容置腔2内壁开设盲孔3后，竹板厚度变薄，即可将光亮从盲孔3内透射至称重平台1的顶侧。
在电器盒11的底部固定有电路板13，电路板13设置用于显示称重结果的显示装置4，本实施例中，显示装置4采用为向盲孔3内延伸的发光LED，发光LED发出的光亮通过盲孔3及及盲孔3底部的透光薄膜后向外散发。本实施例中，盲孔3围成若干日字型显示图案，光线分别透过不同的盲孔3，从而构成不同的显示数字。
参照图3及图4，称重平台1的底侧还设置用于输出与承重大小相对应测量信号的称重传感器5，本实施例中，称重传感器5采用四角传感器，数量为4，分别设置于称重平台1的边角，加大传感器检测的力臂，增强检测精度。
另外，为了进一步提升检测精度，称重传感器5电性连接有用于给称重传感器5提供稳定电压的稳压电路8，本实施例中，稳压电路8包括两部分，一部分为7533芯片，另一部分为XC6204芯片。
称重传感器5电性连接处理器模块6，处理器模块6基于测量信号计算称重结果，本实施例中，处理器模块6包括CSU18M芯片。CSU18M芯片还支持对体脂、心率等的数据分析，功能拓展丰富。
此外，处理器模块6电性连接驱动显示装置4显示预设时长称重结果的驱动电路7，本实施例中，驱动电路7采用为tm1629a芯片。驱动电路7驱动显示装置4显示的时长为预设时长。
参照图4，盲孔3的内壁设置荧光块9，具体为通过针脚安装，在荧光块9外围套设光致变色罩91，说明书附图4为方便示意荧光块9结构，将光致变色罩91剖开示意，而实际的结构为光致变色罩91将荧光块9与光亮完全遮盖。光致变色罩91采用为席夫碱类或占吨类化合物，其在受到显示装置4标准时长的光照后变为透明。其中标准时长小于预设时长，即能够保证光致 变色罩91变为透明，给荧光块9以足够光照时间。
另外，盲孔3的内壁涂覆反光涂层，用于提高光的利用率，增强显示亮度，本实施例中反光涂层采用为反光漆。
本实施例的工作原理：
将显示装置4隐藏在称重平台1内，并且在显示装置4未进行显示时，称重平台1呈一个整体，不会突兀的表现为一个体重秤，易于搭配环境，具有隐层的效果。
在进行测量时，称重传感器5获取四个边角受到的重力大小，之后传送至处理器模块6，处理器模块6通过预置的算法对重力大小进行分析，综合计算处当前所受到的重力大小，并且将称重结果发送至驱动电路7，驱动电路7将称重结果转化为显示信息，经由显示装置4进行显示，发光LED点亮后透过盲孔3的透光内壁，向称重平台1的顶侧发出，进而被人体观察得到。
而在显示装置4显示达标准时长时，光致变色罩91变为透明，光线照射至荧光块9，荧光块9开始吸收光能，而在显示装置4的显示时长达到预设时长时，显示装置4停止光照，而此时荧光块9开始发光，继续保持一段时间的显示效果，更为节能。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
