相关申请的交叉引用
本申请要求于2019年7月16日提交的申请号为2019106395638，发明名称为“货柜”的中国专利申请的优先权，其通过引用方式全部并入本公开。
技术领域
本公开涉及货品陈列、存储或者售卖技术领域，尤其涉及一种货柜。
背景技术
请参见图1和图2，其示出了重力货柜的局部结构示意图，包括沿着柜体高度方向分布于柜体内部的搁架组件。搁架组件包括搁架、支架、和重量传感器等结构。具体的，重力货柜都是通过在普通的搁架1和支架2之间放置重量传感器3的方式获取到重量的变化，然后判断货品的类别。图1给出了重力货柜内两层搁架组件的安装关系。以图1中情形为例，在两层搁架组件之间放了两盒桶装面4。
结合图1和图2，可知现有技术的重力货柜存在以下问题：
首先，重量传感器3会受到货品的干扰而引发结果不准确，货品堆叠之后，由于每层搁架1高度限制，货品和上一层的支架2相互挤压，下面一层搁架1的重量传感器3感应的重力数据会高于实际的重力值。
重量传感器3裸露在外，当用户将货品放置到货柜中时，货品有可能会接触到重量传感器3。尤其是对于一些占用空间较小的货品，其可以放置于搁架1和支架2之间的空隙中，进而严重影响重量传感器3的数值精度。
最后，取放货品的时候，货品可能会卡在上层支架2与下层搁架1之间，导致重力识别出现错误。尤其当搁架1包括托盘和挡板的时候，货品可能会卡在上层支架2和挡板之间。
发明内容
本公开旨在至少解决现有技术或相关技术中存在的技术问题之一。

在一个实施例中，所述护板和所述安装座前侧以及后侧分别通过第一连接板和第二连接板封装，且所述重量传感器和所述支撑件均位于所述第一连接板和第二连接板之间。
在一个实施例中，所述护板为实心板、格栅板或者网板。

本公开的技术方案具有以下优点：本公开实施例的该种货柜，搁架与 搁架组件一一对应，并且搁架以及搁架组件均为多层，并且除了最底层的搁架之外，至少有一层搁架包括安装座和护板，进而对于包括安装座和护板的搁架而言，当其下层搁架上的货品挤压护板的时候，护板会将受到的力传递给安装座，并最终通过搁架对应重量传感器检测出来。由此，该种包括安装座和护板的搁架，其可以反映出下层搁架上货品受到的外力，进而得到下层搁架上货品的实际重量变化。进而，该种货柜即使存在货品挤压搁架，也不会导致依靠重力传感器测得的重量判断商品类别时出现大错误。

具体实施方式
下面结合附图和实施例对本公开的实施方式作进一步详细描述。以下实施例用于说明本公开，但不能用来限制本公开的范围。
在本公开的描述中，需要说明的是，术语“中心”、“纵向”、“横向”、“上”、“下”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开 的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本公开的描述中，需要说明的是，除非另有明确的规定和限定，术语“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
在本公开的描述中，需要说明的是，“前”、“后”、“左”、“右”、是基于柜体实际使用时用于的方位来判断的。
请参见图3和图4，实施例的货柜，包括柜体8，柜体内部固定有多层搁架组件。对于每层搁架组件而言，都包括支撑件6、重量传感器3和搁架1。其中，支撑件6固定于柜体内；重量传感器3安装于支撑件6上；搁架1通过支撑件6固定于柜体内。对于柜体内的多层搁架组件而言，至少其中一个上层搁架组件，其搁架1包括位于重量传感器3上方、并将搁架1自重和/或载重传递给重量传感器3的安装座101，以及位于支撑件6下方、用于阻止下层搁架1的货品接触支撑件6的护板102。
需要说明的是，对于每层搁架组件而言，其重量传感器3的数量可以是一个也可以是多个；同样的，对于每层搁架组件而言，支撑件6的数量也不受限制，只要满足重量传感器3的安装以及搁架的固定即可。
对于安装座101和护板102，其具体的结构形式不受限制。安装座101只要满足该目的即可：搁架1通过安装座101将搁架1受力传递至重量传感器3。同样，护板102只需要满足该目的即可：当下层搁架1上的货品尺寸较大进而挤压上层搁架1的时候，在护板102的作用下，下层货品的挤压力不会传递给支撑件6，而是通过搁架1的护板102传递至安装板。
再者，“上层搁架组件”是一个相对概念，只要在当前搁架组件下方还存在搁架组件，那么当前搁架组件就可以称之为“上层搁架组件”。并且，每层搁架组件和每层搁架1是一一对应的，例如，第一层搁架组件对应第一层搁架，第二层搁架组件对应第二层搁架。
该种货柜，搁架1为多层(搁架组件为多层，则搁架1也为多层)，并且除了最底层的搁架1之外，至少有一层搁架1包括安装座101和护板 102，进而对于包括安装座101和护板102的搁架1而言，当其下层搁架1上的货品挤压护板102的时候，护板102会将受到的力传递给安装座101，并最终通过搁架1对应重量传感器3检测出来。由此，该种包括安装座101和护板102的搁架1，其可以反映出下层搁架1上货品受到的外力，进而得到下层搁架1上货品的实际重量变化。进而，该种货柜即使存在货品挤压搁架1，也不会导致依靠重力传感器测得的重量判断商品类别时出现大错误。
在一个实施例中，货柜的所有搁架1都包括安装座101和护板102。
以图3为例，搁架组件总共为四层，搁架1对应的也为四层。其中，搁架组件包括位于柜体顶部的第一搁架组件，位于柜体中部的第二搁架组件，以及位于柜体底部的第三搁架组件。为了区分第一搁架组件、第二搁架组件和第三搁架组件的搁架，将第一搁架组件的搁架称之为第一搁架，第二搁架组件的搁架称之为第二搁架，第三搁架组件的搁架称之为第三搁架。
并且，需要说明的是，位于柜体顶部的第一搁架组件也即柜体内从上往下的第一层搁架组件；位于柜体底部的第三搁架组件也即柜体内从上往下的最后一层搁架组件；位于柜体中部的第二搁架组件也即从柜体内从上往下位于第一搁架组件和第三搁架组件之间的搁架组件。
其中，第一搁架位于柜体8顶部。进而，该第一搁架可以防止货品接触柜子顶部进而导致搁架1受到货品重量之外的外力。需要说明的是，第一搁架并不用于放置货品，货品放置在第二搁架和第三搁架上。
此外，第二搁架位于柜体8顶部和顶部之间，并且所有第二搁架上方均可以用于放置货品。进而，第二搁架的安装座101可以采用托盘的形式，并通过托盘支撑货品。当然，安装座101的具体形式不受此处举例的限制，只要可以满足货品的摆放和支撑即可。例如，安装座101可以采用板状的结构形式、块状的结构形式、网状的结构形式等。
在一个实施例中，请再次参见图4，托盘上方边沿位置设置有挡板1011。通过挡板1011的设置，可以防止货品直接接触柜体8的侧壁，保证托盘上货品的重量都传递给重力传感器。此外，挡板1011的设置可以避免货品漏至下层搁架。
需要说明的是，虽然图3和图4中，第三搁架包括安装座101和护板102，但是第三搁架也可以通过现有技术当中的搁架结构进行替换。具体的，图3和图4当中，虽然位于柜体8底部的第三搁架包括护板102，但是由于第三搁架底部不放置货品，进而不会存在货品挤压搁架1的问题。因此，第三搁架也可以不包括护板，并且，第三搁架可以直接通过像背景技术当中的搁架一样直接通过支架固定至柜体中。进而，对于第三搁架而言，用于固定其的支撑件采用背景技术当中的支架即可。此时，对于第三搁架而言，其底面直接安装于重量传感器的上方。
在一个实施例中，货柜的搁架1中，并非所有上层搁架1都包括安装座101和护板102，也可以选择只有部分上层的搁架1采用图4当中的结构形式，对应的为了防止货品挤压搁架1导致对货品重量的误判，可以选择将尺寸较大有可能会挤压搁架的货品放至在图4所示搁架1的下方空间中。
在一个实施例中，护板102和安装座101前侧以及后侧分别通过第一连接板103和第二连接板104封装，且重量传感器3和支撑件6均位于第一连接板103和第二连接板104之间。也即，护板102、安装座101、第一连接板103和第二连接板104之间形成容纳空间7，重量传感器3和支撑件6均位于容纳空间7中。该种情况下，形成有容纳空间7的搁架1，可以避免重量传感器3外露，防止货品接触重量传感器3，保证重量传感器3的检测精度。并且，由于支撑件6和重量传感器3位于容纳空间7中，进而可以避免货品取放时被卡住的问题。
其中，护板102的具体结构形式不受限制，例如护板102可以为实心板、格栅板或者网板等。
另外，通过图3和图4发现，搁架1通过垫块5安装于重量传感器3。具体的，安装座101位于垫块5的上方，垫块5位于重量传感器3的上方。通过垫块5的设置，可以防止搁架1直接接触重量传感器3，进而防止重量传感器3被损坏。
重量传感器3的具体形式不受限制，只要受力的时候可以反映出受力大小即可。例如，重量传感器3可以采用秤台。而采用秤台的好处在于，不论是朝上安装还是朝下安装，秤台都可以满足搁架1的重量测量需求。
支撑件6的具体结构形式不受限制，只要满足重量传感器3的安装，并可以将搁架1安装至柜体8内即可。例如，支撑件6可以包括支撑板、支撑条或者支撑块中的任意种。也即，支撑件6可以为支撑板、支撑条或者支撑块中的任意一种，也可以包括支撑板、支撑条或者支撑块中的任意多种。
图3和图4中，支撑件6采用支撑板的形式，支撑件6的左、右两端固定至柜体8侧壁。其中，为了便于支撑板的安装，支撑板的前、后两侧(也即图3和图4当中的左、右两侧)均和搁架1之间存在一定的间隙。此外，支撑板的底部与搁架1护板102的上方之间存在间隙。进而，当货品挤压搁架1的护板102的时候，护板102不会将力传递给支撑板，而是全数传递至安装座，进而通过重量传感器3检测到。
本公开中的货柜可以为无人零售柜、智能冰箱或者展柜等，并不受此处举例的限制，任何用于货品陈列、存储或者售卖等用途的货柜，都可以采用上述结构。
其中，无人零售柜和展柜均包括两种情形，分别是有门体和没有门体的情形。当无人零售柜包括门体的时候，则其柜体8一般采用箱体结构；当无人零售柜没有门体的时候，则其柜体8一般采用框架结构。同样的，对于展柜而言，其柜体8也包括箱体结构形式和框架结构形式。
在一个实施例中，货柜包括控制器，控制器连接重量传感器3，获取发生货品变化的搁架1上的检测重量变化值△G 1，以及发生货品变化的搁架1的上层搁架1的检测重量变化值△G 2，将△G 1-△G 20的值作为实际重量变化值△G。
其中，△G 1以及△G 2都取正数。
进而，通过△G可以准确判断出搁架1上货品的重量变化，进而基于货品的重量变化准确的判断出取放的货品以及数量。
也即，当某层搁架1上的商品顶到位于上部的搁架1时，当前搁架1和上部搁架1受到外力作用将相互抵消，进而可以得出正确的货品重量，避免了出现错误的情况。
当货柜为无人零售柜的时候，上述提及的货品也即售卖的商品。无人零售柜的后台录入对应商品的重量，在必要的时候根据控制器得到的实际 重量变化值△G来判断商品的品类，从而得出商品价格，完成扣款交易等。
当货柜为智能冰箱的时候，上述提及的货品也即蔬菜、水果、鱼肉等食物。智能冰箱的后台录入对应食物的重量，得到智能冰箱当中对应食物的变化量，进而在必要的时候提醒用户补给。
以上实施方式仅用于说明本公开，而非对本公开的限制。尽管参照实施例对本公开进行了详细说明，本领域的普通技术人员应当理解，对本公开的技术方案进行各种组合、修改或者等同替换，都不脱离本公开技术方案的精神和范围，均应涵盖在本公开的权利要求范围当中。
