本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
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，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明，若本发明实施例中有涉及方向性指示（诸如上、下、左、右、前、后……），则该方向性指示仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本发明实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
参照图1至图7，本发明提供的一种地毯秤，适合家庭居住综合使用环境，本发明是在人体秤上取消秤脚可放置在家庭内软地毯上或硬底板及凹凸不平的地面进行精确测量。
本发明实施例所述的地毯秤包括面板10以及底板20，所述面板10上装设有电路板80以及与所述电路板80连接的传感器70，所述传感器70的感应端背离所述面板10朝所述底板20方向延伸，所述底板20上与所述面板10相对的一侧设有刚性板40，所述传感器70随所述面板10受力往所述底板20运动时所述感应端将力传递到所述刚性板40上，其中，本发明所述刚性板40为镀锌钢板，所述传感器70为重力传感器70。
所述传感器70的感应端可直接与所述刚性板40接触，也可以间接跟所述刚性板40接触，在所述面板10上不受力时，只有所述面板10以及装设在所述面板10上包括传感器70以及电路板80在内的部件的重力作用在所述刚性板40上，此时所述传感器70处于与所述刚性板40正常接触范围内，在所述面板10上受力时，所述传感器70发生形变，以通过检测所述传感器70的变形量获取作用在所述面板10上的力，而所述传感器70上受的力传递到所述刚性板40上。
优选地，所述传感器70的感应端与所述刚性板40间接接触，也即所述地毯秤还包括支撑件60，所述支撑件60位于所述刚性板40与所述传感器70之间，所述支撑件60与所述传感器70的感应端接触，所述传感器70器随所述面板10受力往所述底板20运动时所述感应端通过所述支撑件60将力传递到所述刚性板40上。所述支撑件60通过胶水粘接于所述刚性板40上，可以理解的是，所述支撑件60为柱状支撑件60。
具体地，所述支撑件60包括安装端和抵接端，所述安装端尺寸小于所述抵接端尺寸，所述刚性板40安装所述支撑件60的位置设有安装孔，所述支撑件60的安装端嵌入所述安装孔中，以限定所述安装件的位移，可以理解的是，所述支撑件60与所述安装孔可通过过盈配合固定，也可以通过胶水粘接固定。
在其他实施例中，所述面板10上还设有显示屏，所述显示屏用于显示体重数字，所述面板10设置所述显示屏的一面设有玻璃盖板30，所述玻璃盖板30用于保护所述面板10，所述面板10与所述玻璃盖板30可以通过胶粘固定，也可以通过螺丝固定。
所述电路板80包括放大电路、模数转换器以及中央处理器，所述放大电路与所述传感器70连接，所述传感器70在面板10上受重力下压时发生形变，传感器70的阻抗发生变化，进而使得激励电压发生变化，所述传感器70输出一个变化的模拟信号，该模拟信号经所述放大电路放大后输出到所述数模转换器，所述数模转换器将该模拟信号转换成便于中央处理器处理的数字信号，并将该数字信号输出到中央处理器，所述中央处理器接收到该数字信号后进行运算处理，并将运算结果显示在显示屏上，供用户获取体重信息。
所述地毯秤上还设有USB接口50，所述USB接口50与所述电路板80连接，所述USB接口50用于传输数据以及用于供所述地毯秤与电源连接，实现给地毯秤充电。
本发明实施例地毯秤测量原理：在面板10上施加重力时，重力通过所述面板10传递到所述传感器70上，所述传感器70将力传递到所述刚性板40上，所述刚性板40反向作用于所述传感器70上，使得所述传感器70发生变形以检测所施加的重力大小，基于所述刚性板40不易于形变，当地毯秤放在轻软地毯上进行称重时，所述传感器70上的力也不会传递到地毯上，防止地毯对地毯秤产生卸力作用，实现地毯秤在地毯或凹凸不平地面上称重时的精准测量。基于此，本发明实施例也可以直接将地毯秤的秤脚隐藏在所述面板10与所述刚性板40之间，以实现地毯或凹凸不平底面上称重时精准。
进一步的，所述底板20为塑胶底板20，所述底板20与所述刚性板40扣合连接和/或采用热烫胶柱固定。具体而言，所述底板20设有扣件，而所述刚性板40上设有与所述扣件相适配的卡件，所述扣件穿设所述刚性板40，与所述扣件扣合以固定所述底板20与所述刚性板40，为了加固所述底板20与所述刚性板40的连接，所述底板20与所述刚性板40之间还设有胶柱热压固定。可以理解的是，所述底板20与所述刚性板40的扣合连接方式具有多种，基于本发明通过扣合方式连接的结构都属于本发明保护范围，再次不一一列举。
本实施例地毯秤包括面板10以及底板20，所述面板10上装设有电路板80以及与所述电路板80连接的传感器70，所述传感器70的感应端背离所述面板10朝所述底板20方向延伸，所述底板20上与所述面板10相对的一侧设有刚性板40，在所述面板10上受力时，通过所述传感器70将力传递到刚性板40上，当地毯秤放在轻软地毯或凹凸不平地面上进行称重时，传感器70上的力也不会传递到地毯或地面上，基于刚性板40不易于变形卸力，地毯或地面对地毯秤不产生卸力作用，提高地毯秤称重的精准度。
所述面板10上设有多个贯穿所述面板10的通孔，所述通孔用于穿设所述传感器70，所述传感器70通过卡扣的方式固定在所述通孔内。可以理解的是，所述传感器70与所述面板10具体可以通过在所述通孔的内壁上设有卡槽，在所述传感器70的外围设置凸台，将所述传感器70装设入所述通孔内时，所述凸台卡入所述卡槽中，实现所述传感器70安装在所述面板10上；或者，所述通孔的周向设有弹性固定件，所述传感器70穿设在所述通孔后，通过所述弹性固定件固定所述传感器70，具体所述弹性固定件可以为弹性扣件。
所述地毯秤包括至少四个所述传感器70，所述传感器70沿所述面板10的周向均匀分布，也即所述面板10上设有至少四个所述安装孔，所述安装孔沿所述面板10的周向均匀分布。在所述面板10呈方形时，所述传感器70分布在所述面板10是四个角，在所述面板10呈圆形时，所述传感器70分布在所述面板10的周边。
在本发明实施例中，所述面板10与所述底板20之间为活动连接，如所述面板10与所述底板20之间通过可拆卸扣件和/或弹性连接件110连接。
优选地，所述面板10与所述底板20之间设置有弹性连接件110连接，所述弹性连接件110在所述面板10受力时与所述传感器70同向变形。也即所述面板10与所述底板20之间通过所述弹性连接件110连接实现面板10与所述底板20之间可活动，如在所述面板10下压重力时，所述面板10可以朝所述底板20方向运动，或者提取所述面板10时，所述面板10可以朝背离所述底板20方向运动。
本实施例中，所述弹性连接件110可设置多个，所述弹性连接件110沿所述面板10的周向均匀分布，尤其是设置在分布有所述传感器70的位置。
进一步地，所述弹性连接件110包括与所述面板10连接的弹性连接部111以及通过所述弹性连接部111连接所述面板10的固定部112，所述固定部112与所述底板20固定连接。
具体而言，所述固定部112用于限定所述面板10与所述底板20之间的水平运动，所述面板10与所述底板20之间通过所述固定部112限制所述面板10与所述底板20前后左右四个方向运动，避免水平方向移动干涩准确度测量。而所述弹性连接部111连接所述面板10与所述固定部112，基于所述弹性连接部111具有弹性，实现所述固定部112可在所述弹性连接部111的弹性形变方向活动，本实施例中，所述弹性连接部111在所述面板10与所述底边之间弹性形变。
更进一步地，所述固定部112为由所述弹性连接部111朝所述底板20延伸的固定柱，所述固定柱的轴向设有螺纹孔，所述底板20与所述固定部112通过螺丝与所述定位柱的螺纹孔配合固定。在本实施例中，所述底板20上设有与所述螺纹孔对应的装配孔，同样的，所述刚性板40上也设有与所述螺纹孔对应的通孔，通过将螺丝穿过所述底板20和刚性板40，与所述螺纹孔配合锁紧所述底板20与所述固定柱，如此，所述固定部112与所述底板20之间通过螺丝固定，固定方式简单，且易于操作。
所述弹性连接部111为所述固定柱径向分布的网状弹性体，所述网状弹性体背离所述固定柱一端延伸至所述面板10，与所述面板10连接。可以理解的是，所述弹性连接部111均匀分布在所述固定柱径向形成所述网状弹性体，所述弹性连接部111的尺寸较小，使得地毯秤在未使用的情况下，传感器70的感应点除了将地毯秤本身的重量压在所述钢板上以外，不会对传感器70施加拉力，导致称重不准；同样地，使用地毯秤时，传感器70在面板10施加下压力时，弹性连接部111随所述传感器70变形而发生变形，基于所述弹性连接部111的尺寸较小，软度大，所述弹性连接部111不会施加力于所述传感器70上，不影响测量的精度。
为了实现所述弹性连接件110在所述面板10受力，随所述传感器70形变时，所述弹性件具有足够的形变空间，设置所述固定柱背离所述底板20的端部与所述面板10的顶部之间具有间隙，所述间隙为所述弹性连接件110的变形空间，具体可以通过设置所述固定柱与所述面板10的顶部平面不平齐，以形成所述间隙，所述间隙的大小为2.0mm以上。
可以理解的是，本发明实施例中的所述弹性连接件110可以与所述面板10一体成型，也可以通过粘接方式与所述面板10固定，基于所述弹性连接件110的结构复杂，为了省去繁琐的加工工艺，优选所述弹性连接部111与所述面板10一体成型。
本实施例中，所述面板10与所述底板20采用多个所述弹性连接件110进行连接，当人体秤重时传感器70产生形变时，所述弹性体会同时形变，且所述弹性体的形变方向与所述传感器70的形变方向相同，基于所述弹性体发生形变，所述面板10与所述地面的连接位置不会产生卸力导致秤重不准的现象，从而进一步提高地毯秤测量的准确度。
在本发明实施例中，所述面板10与所述底板20之间可通过弹性连接，也可以通过卡扣连接，或者所述面板10与所述底板20之间通过弹性连接，同时通过卡扣连接固定。
具体而言，所述面板10与所述底板20之间通过卡扣连接时，可以通过设置第一卡扣120组件与第二卡扣210组件的卡扣位置以及卡扣方向不同，实现既能连接，有能在面板10上不施加重力时，所述面板10与所述底板20之间不受力，不影响地毯秤的测量精度。
优选地，所述面板10与所述底板20之间通过弹性连接，通过卡扣限定面板10与底板20的弹性极限位移。如所述面板10朝所述底板20方向延伸有第一卡扣120，所述底板20槽所述面板10方向延伸有与所述第一卡扣120相适配的第二卡扣210，所述第一卡扣120与所述第二卡扣210的扣合位置具有间隙，所述第一卡扣120与所述第二卡扣210在所述面板10与所述底板20之间的间隙增大时卡合。
具体而言，在所述面板10上没有受重力时，所述第一卡扣120与所述第二卡扣210的扣合位置具有间隙，面板10与刚性板40之间只有传感器70位置以及弹性连接件110位置处接触，基于弹性连接件110的弹性连接部111的软度，所述地毯秤自身重力作用于所述传感器70位置，提高地毯秤的精准度。人提取面板10时，基于连接所述面板10与所述底板20的弹性连接件110具有弹性，所述面板10与所述底边之间的间隙增大，在所述面板10与所述底板20之间的间隙增大到一定值时，所述第一卡扣120件与所述第二卡扣210件卡合固定，限定所述面板10与所述底板20的移动。
在人提取面板10时，若所述面板10与所述底板20之间仅通过所述弹性连接件110连接时，基于所述弹性连接件110的软度，容易造成弹性连接件110弹性无法复位，甚至拉断所述弹性连接件110，因此设置所述第一卡扣120与所述第二卡扣210在所述面板10与所述底板20之间的间隙增大时卡合所述面板10与所述底板20，有效保护所述弹性连接件110。
所述第一卡扣120与所述第二卡扣210的结构有多种，本发明实施例优选采用简单易于实现的结构，如所述第一卡扣120包括朝所述底板20方向延伸的第一连接部以及垂直所述第一连接部延伸方向凸设的第一卡扣120部；所述第二卡扣210包括朝所述面板10方向延伸的第二连接部以及垂直所述第二连接部延伸方向凸设的第二卡扣210部，所述第一卡扣120部面向所述面板10的面与所述第二卡扣210部面向所述底板20的面为所述扣合位置，所述第一卡扣120部的扣合面与所述第二卡扣210部的扣合面具有所述间隙。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者系统不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者系统所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者系统中还存在另外的相同要素。
上述本发明实施例序号仅仅为了描述，不代表实施例的优劣。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
