Description

一种电子秤 技术领域
本发明涉及物体称重技术，尤其涉及一种电子秤。
背景技术
对于现有的传统秤技术特点对于称重的条件比较苛刻，只能够在坚硬且平整的平面才能进行准确称重，但是在地毯、砂砾、泥土、防滑垫等上面则无法实现准确称重。
目前市场上在人体秤这个领域，还没有一款产品真正意义上讲可以具备无障碍的称重的产品，这就带来一个问题，对于称重条件的一个致命限制，而且作为居家类的人体健康秤系列产品，随着地毯、防滑垫等成为居家的必备产品的同时给人体秤的使用带来的致命的限制，出于对此现实背景的考虑，因此设计一款无障碍称重的电子秤对于居家来说显得格外的必要与迫切。
传统的电子秤方案都是通过四个传感器配合四个支撑脚受力。面板承受一个自上而下的重力时，力通过面板传递到传感器并通过支撑脚最终接触地面支撑点，在传感器受力时，由于力传输途中有四个支撑脚的支撑，会产生一个扭曲的力，这个力的方向会根据地面的凹凸不平、坚硬柔软程度等，它的扭曲方向发生改变，而并非完全产地给了传感器形成支撑力，这个就是力的损耗。当电子秤处于不平的地面上时，支撑脚处于点受力，因此产生的变形扭力方向分散，大部分的力损耗在支脚上，而没有集中作用于传感器上，造成传感器取数不准确，并且由于地面状况复杂，软件很难修正。另外，传感器与支撑脚之间为抵接式连接，受地面的影响，存在悬空不平导致部分传感器没有受力，进而导致最终称重数据不准确。
发明内容
本发明所要解决的技术问题在于，提供一种电子秤，可以适用于多种地面情况，且保证称重数据准确。
为了解决上述技术问题，本发明的实施例提供了一种电子秤，包括面壳及底壳，所述面壳与所述底壳之间通过四个传感器装置连接，所述传感器装置包 括第一固定端和第二固定端，所述第一固定端和第二固定端为一体式结构，二者之间受力形变以产生感应信号，所述第一固定端与底壳固定连接，且所述第一固定端与所述面壳之间形成有间隙；所述第二固定端与所述面壳固定连接，且所述第二固定端与所述底壳之间形成有间隙。

其中，所述第一固定端与所述底壳之间为面面贴合式固定连接；所述第二固定端与所述面壳之间为面面贴合式固定连接。
其中，两个所述固定端与所述底壳及所述面壳之间均为面面贴合式固定连接。
其中，所述面壳与所述底壳均为方形，四个所述传感器装置分别设置在所述底壳的四个边角处。
其中，所述电子秤还包括处理器，所述处理器同时电连接于四个所述传感器装置。
其中，所述电子秤还包括电池盒，所述电池盒固定于所述底壳，且电连接至所述处理器；所述处理器及电池盒均设置在所述底壳上。

本发明实施例提供的电子秤，由于传感器装置直接与面壳及底壳固定连接，面壳及底壳与均整体向四个传感器装置施力，可以直接将受力传递给传感器装置，保证受力完整传递给传感器装置，有效避免了支撑脚导致力扭曲的问题，在称重过程中，传感器装置与面壳及底壳之间不会存在悬空的问题，无论 何种地面情况下，四个传感器装置均可以受力，保证称重数据准确。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明优选实施例提供的电子秤的分解示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
参见图1-2，为本发明中优选实施例提供的一种电子秤，包括面壳1及底壳2，面壳1与底壳2之间通过四个传感器装置3连接，各传感器装置3包括第一固定端31和第二固定端32，第一固定端31和第二固定端32为一体式结构，二者之间受力形变以产生感应信号，第一固定端31和第二固定端32分别固定连接至面壳1及底壳2。
第一固定端31与底壳2固定连接，且第一固定端31与面壳1之间形成有间隙；第二固定端32与面壳1固定连接，且第二固定端32与底壳2之间形成有间隙，利用间隙可以使得面壳1与底壳2之间可以相对移动使得第一固定端31与第二固定端32之间形变产生感应信号。
本发明提供的电子秤，由于传感器装置3直接与面壳1及底壳2固定连接，面壳1及底壳2与均整体向四个传感器装置3施力，可以直接将受力传递给传感器装置3，保证受力完整传递给传感器装置3，有效避免了支撑脚导致力扭曲的问题，在称重过程中，传感器装置3与面壳1及底壳2之间不会存在悬空的问题，无论何种地面情况下，四个传感器装置3均可以受力，保证称重数据准确。
底壳2的外底面为平面状，以增大底壳2与地面的接触面积，便于底壳2的受力，保证底壳2受力较为均匀，可以较好地整体向传感器装置3施加作用 力。
本实施例中，第一固定端31为环状，第二固定端32位于第一固定端31的环内，通过将第二固定端32设置在第一固定端31的环内，在第一固定端31与第二固定端32之间的形变发生在第一固定端31的环内，避免形变受外界的干涉，保证数据监测的准确性。作为优选，第一固定环为方形环状，以节省空间，利于电子秤内部结构紧凑。当然，在其他实施方式中，第一固定端31也可以为圆形环状，三角形环状，或其他形状。另外，也可以是，第二固定端32为环状，第一固定端31位于第二固定端32的环内。
作为优选，所述第一固定端31与所述底壳2之间为面面贴合式固定连接；所述第二固定端32与所述面壳1之间为面面贴合式固定连接。以保证作用力可以较好的传递给传感器装置3，保证称重数据准确。
第一固定端31与底壳2之间可以通过多种方式固定连接，包括但不局限于螺钉、铆接、焊接、粘接等，第一固定端31与底壳2之间可以直接固定连接，也可以通过各类固定连接件进行连接。
第二固定端32与面壳1之间可以通过多种方式固定连接，包括但不局限于螺钉、铆接、焊接、粘接等，第二固定端32与面壳1之间可以直接固定连接，也可以通过各类固定连接件进行连接。
第一固定端31及第二固定端32的形状并不局限于上述形状，传感器装置3还可以为长条形，其两端分别为第一固定端31和第二固定端32，且分别固定连接至底壳2和面壳1。或者，传感器装置3为E型，位于内侧的支臂形成第一固定端31，位于外侧两个支臂形成第二固定端32。在面壳1受力时，第一固定端31与第二固定端32之间可以产生形变即可。
面壳1与底壳2均为方形，四个传感器装置3分别设置在底壳2的四个边角处。四个传感器装置3可以呈矩形排布，且相对靠近底壳2及面壳1的边缘处，从而保证四个传感器装置3均可以受力，且力可以相对的均布在四个传感器装置3上。
电子秤还包括处理器4，处理器4同时电连接于四个传感器装置3。利用处理器4可以对四个传感器装置3的感应数据进行分析处理，从而得出所称物体的重量。四个传感器装置3按照惠斯顿电桥原理分布，四个传感器装置3按 照顺时针或者逆时针方向分布即可，每相邻的两个传感器装置3组成一个桥路，四个传感器装置3组成一个完整的桥路。
电子秤还包括电池盒5，电池盒5固定于底壳2，且电连接至处理器4；利用电池盒5可以容纳电池，以对处理器4进行供电，从而可以向传感器装置3施加电压信号，以获取四个传感器装置3的感应信号。处理器4及电池盒5均设置在底壳2上，以方便处理器4、电池盒5与四个传感器装置3之间的电连接，其导线布局在底壳2上即可，无需设置到面盖上，以避免导线对底壳2及面壳1之间受力的影响。
电子秤还包括无线传输模块(图中未示出)，无线传输模块电连接至处理器4，通过无线传输模块，处理器4可以将称重结果数据发送到手机、平板电脑等终端设备上，以供使用者查看。
电子秤还包括显示屏6，显示屏6电连接至处理器4，通过显示屏6可以显示称重数据，以便使用者观看。显示屏6可以设置在面壳1上，或者，显示屏6可以设置在底壳2上，显示屏6朝向面壳1设置，且面壳1对应显示屏6的部分为透明状，从而可以透过面壳1看到显示屏6，以减小底壳2与显示屏6之间的连接部件，使得底壳2与显示屏6之间仅通过传感器装置3连接，使得受力可以完全传递至传感器装置3，保证称重数据的准确性。底壳2与面壳1之间仅通过四个传感器装置3连接，无其他连接关系，避免其他连接关系对受力造成影响。
此处，电子秤在设置有无线传输模块式，可以不设置显示屏6，使用者可以在手机、平板电脑等终端上查看数据。
以上的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
