Description

阶梯式电池
技术领域
本发明涉及阶梯式电池,涉及能够提高系统内部空间的利用率的阶梯式电池。
背景技术
本申请基于2015年3月16日提出申请的韩国专利申请第10-2015-0036110号主张优先权,相应韩国专利申请的文献所公开的全部内容援引于本申请。
近来,各种电子产品的形状在多样化,另外随着小型化、扁平化,以以往的长方体形状的电池难以高效地使用多样化的形状及小型化且扁平化的电子产品的内部空间。
由此,为了配合在电子产品内部收容电池的空间的形状,电池的形状也脱离长方体形状而制造成多种形状,其中之一为阶梯式电池(Stepped Battery)。
以下的现有技术文献(韩国公开专利公报第10-2015-0007971号)中详细说明了这样的阶梯式电池的一例。
但是,在以往的阶梯式电池中,无法以配合系统内的多种形状的空间的方式将阶梯式电池的形状形成为最优而成为问题。
并且,存在较多必须使用保护电路模块(Protection Circuit Module,PCM)或其他电路板(board)情况,但是为了配置它们而另行需要空间,因此会产生在有限的空间内无法高效地进行配置的问题。

发明效果
本发明的阶梯式电池包括第一单元电池及层叠于第一单元电池的一面且宽度小于第一单元电池的多个第二单元电池,第二单元电池相互隔开配置,从而能够使系统内部空间的利用率最大化而实现最优化的电池形状。

具体实施方式
以下,参照附图,详细地说明本发明的优选的实施例。但是,本发明并不限定或局限于以下的实施例。
实施例1
图1是表示本发明的实施例1的阶梯式电池的立体图。图2是表示本发明的实施例1的阶梯式电池的主视图。图3是表示本发明的实施例1的阶梯式电池的侧视图。
以下,参照图1~图3,说明本发明的实施例1的阶梯式电池。
本发明的实施例1的阶梯式电池(100)包括第一单元电池(110)及第二单元电池(130)。
第一单元电池(110)可以是构成基体的单元电池。并且,第一单元电池(110)可以是位于比如下说明的第二单元电池(130)靠下层的单元电池。
第二单元电池(130)可以具有宽度比第一单元电池(110)窄且层叠于第一单元电池的一面(111)上的形态。第二单元电池(130)可以由配置在第一单元电池的一面(111)上的多个第二单元电池(130)构成。
图1~图3示出了在第一单元电池的一面(111)、即第一单元电池的上表面上配置的两个第二单元电池(130)。为方便说明,以图2为基准,将位于左侧的第二单元电池称为左侧第二单元电池(131),将位于右侧的第二单元电池称为右侧第二单元电池(133)。
在本发明的实施例1的阶梯式电池(100)中,第二单元电池(130)可以在第一单元电池的一面(111)上相互隔开配置。参照图2,第二单元电池(130)可以包括左右相互隔开配置的左侧第二单元电池(131)和右侧第二单元电池(133)。
并且,可以在如此相互隔开配置的第二单元电池(130)之间形成隔离空间(S)。图1及图2示出在左侧第二单元电池(131)与右侧第二单元电池(133)之间形成的隔离空间(S)。
在本发明的实施例1的阶梯式电池(100)中,如果第二单元电池(130)以这样的形态隔开配置,则能够使系统内部空间的利用率最大化。
例如,在向具有向阶梯式电池(100)的中央部内侧突出的突出部(未图示)的系统内部插入阶梯式电池(100)的情况下,在本发明的实施例1的阶梯式电池(100)中,隔离空间(S)能够收容这样的突出部。由此,系统内部空间能够没有剩余空间地充分利用,从而能够使空间的利用率最大化。
另一方面,参照图1及图2,第一单元电池(110)或第二单元电池(130)的至少一个以上的角部(150)可以形成为弧形。在如此将角部(150)形成为弧形的情况下,可以进一步保护系统内部的构造物。
如果角部(150)锋利,则可能会损坏系统的内部构造物或对内部构造物产生划痕。另外,锋利的角部还可能会使阶梯式电池(100)的使用者受伤或损坏使用装置。
并且,在本发明的实施例1的阶梯式电池(100)中,多个第二单元电池(130)可以构成为各自的大小及重量彼此相同。在该情况下,由于向第一单元电池(110)的彼此不同的部分(左侧及右侧)施加的压力相同,因此能够形成保持平衡的电池结构。
即,在左右侧的第二单元电池(131、133)的大小及重量彼此不同而向第一单元电池(110)的左右侧施加的应力彼此不同的情况下,力的平衡被破坏,第一单元电池(110)可能变形为畸形的形状。
另外,若单元电池的内部构造物从被施加大的压力的一侧向被施加小的压力的一侧移动,则也可能会导致电池的非正常的运行。
实施例2
图4是表示本发明的实施例2的阶梯式电池的主视图。
本发明的实施例2的阶梯式电池具有与上述的实施例1的阶梯式电池类似的结构。但是,实施例2在还具备保护电路模块这一点与实施例1存在差异。
需要说明的是,对于与上述的结构相同的(或相当的)部分标注相同的(或相当的)附图标记,省略对其详细的说明。
以下,参照图4,说明本发明的实施例2的阶梯式电池。
如图4所示,本发明的实施例2的阶梯式电池(200)可以在隔离空间(S)设置保护电路模块(280)(Protection Circuit Module,PCM)。当然,配置于隔离空间(S)的结构并不限定于保护电路模块(280),也可以配置其他电路板(board)。
如此配置于隔离空间(S)内的保护电路模块(280)能够在阶梯式电池(200)要插入的系统内不另外占用空间而安装于电池,因此能够使系统内部空间最小化,能够更高效地使用空间。
并且,在本发明的实施例2的阶梯式电池(200)中,保护电路模块(280)的高度(J)可以与第二单元电池(130)的台阶的高度(H)相同或比该高度(H)还低。即,换言之,第二单元电池(130)的高度(H)可以是保护电路模块(280)的高度(J)以上。在以这种方式构成保护电路模块(280)的情况下,能够从外部的物体对保护电路模块(280)进行保护。
这作为类似于在战争时能够从飞来的子弹中保护躲在战壕中的军人的原理,通过在向左侧第二单元电池(131)与右侧第二单元电池(133)之间弯入的形状的隔离空间(S)内配置保护电路模块(280),能够从外部的物体对保护电路模块(280)进行保护。
实施例3
图5是表示本发明的实施例3的阶梯式电池的主视图。图6是表示本发明的实施例3的阶梯式电池的俯视图。
本发明的实施例3的阶梯式电池具有与上述的实施例1的阶梯式电池类似的结构。但是,实施例3在还具备电路板这一点与实施例1存在差异。
需要说明的是,对于与上述的结构相同的(或相当的)部分标注相同的(或相当的)附图标记,省略对其详细的说明。
以下,参照图5及图6,说明本发明的实施例3的阶梯式电池。
如图5及图6所示,本发明的实施例3的阶梯式电池(300)可以在隔离空间(S)配置电路板(board)(380)。当然,配置于隔离空间(S)的结构不限定于电路板(380),也可以配置保护电路模块等。
此时,电路板(380)的大小可以与隔离空间(S)的大小对应。特别是,如图5及图6所示,电路板(380)可以构成为尺寸与隔离空间(S)的尺寸正好。在该情况下,即使没有另行固定电路板(380)的装置,电路板(380)也通过摩擦而避免从阶梯式电池(300)分离,通过这种方式,能够将阶梯式电池(300)构成为一体。
并且,在如此以填埋隔离空间(S)的方式安装电路板(380)的情况下,外部壳体(390)不会倾斜或形成台阶而能够维持平整,因此能够实现外观上及实用方面更提高的电池。
