请参阅图1与图2，所述电子装置包括本体10、显示屏模组20、电池30及壳体40。所述本体10包括容纳槽11、电池槽13及电路板15。所述本体10包括第一表面(图未标)及与所述第一表面相对的第二表面(图未标)。所述 容纳槽11位于所述第一表面。所述电池槽13位于所述第二表面。所述电路板15与所述电池槽13相邻设置。所述显示屏模组20上设有柔性电路板21。所述容纳槽11的槽底壁一侧设有开孔112。所述开孔112贯穿所述第二表面设置有电池槽13的一端，也就是说所述开孔112位于第二表面上所述电池槽13远离所述电路板15的一端位置。所述电池30收容于电池槽13内。所述壳体40盖于所述本体10上封闭电池槽13。所述显示屏模组20收容于所述容纳槽11内，所述柔性电路板21穿过开孔112于电池槽13一侧绕至所述电池30朝向所述壳体40的表面上并沿着表面延伸直至与所述电路板15连接。
本实施例中，所述本体10为电子装置前壳，其呈矩形设置。所述本体包括外表面101及与外表面101相对设置的内表面102。所述容纳槽11为矩形凹槽，其设于所述外表面101上，用于收容所述显示屏模组20。所述电池槽13设于所述内表面102一端用于收纳所述电池30。所述电路板15安装于所述内表面102上与所述电池槽13相邻设置。所述壳体40盖设于所述本体10的内表面102上，用于将电池30及电路板15封闭于所述本体10上，本实施例中，所述壳体40为电子装置的电池盖。所述壳体40朝向所述电池的表面可以设置凹部，用于与电池槽13配合收容整块电池30，以减小电子装置整体厚度。所述柔性电路板21具体是绕过电池槽的槽壁延伸至电池槽13上方，即绕至电池槽13开口的上方后与紧贴电池表面并沿着表面延伸至与电路板连接。
请一并参阅图1与图5，进一步的，所述容纳槽11包括槽底壁(图未标)及围绕所述槽底壁设置的槽侧壁(图未标)。所述开孔112设于槽底壁一侧边缘。所述电子装置还包括扬声器(图未标)及扬声器支架17，所述扬声器支架17装于本体10上并夹持于所述开孔112边缘与所述壳体40之间。
本实施例中，所述开孔112设于设于槽底壁边缘，即槽底壁临近槽侧壁位置，所述电池槽13及电路板15安装位置相对开孔112向本体10一侧移动使本体10上预留一定的空间设计所述开孔112。本实施例中，开孔112为矩形且开孔112的尺寸为14×6mm。所述开孔112设于容纳槽11槽底壁边缘，并且开孔112位于电池槽13一侧且不与电池槽贯通。由于开孔112是是位于电池槽一侧从容纳槽11贯穿而不是电池槽13底部，不需要对开孔112位置做减薄尺寸避让，避免电池对开孔112产生正面压力，减小对本体10的整体强度影响。并且所述扬声器支架17抵持所述开孔112边缘，进一步增加了槽底壁 的强度，避免槽底壁变形进而增加本体10的强度。
一并参阅图3与图5，进一步的，所述柔性电路板21包括连接段211、弯折段213及延伸段215。所述弯折段213连接所述连接段211与所述延伸段215。由连接段211延伸的弯折段213及由弯折段213延伸的延伸段215。所述连接段211连接所述显示屏模组20，所述延伸段215与所述延伸段215连接。进一步的，所述显示屏模组20包括玻璃基板22，所述连接段211远离弯折段213的表面部分与玻璃基板22的表面贴合，所述连接段211离弯折段213的表面另一部分伸出所述玻璃基板22并与所述玻璃基板22之间成夹角，所述夹角内设有胶体23。

进一步的，所述弯折段213表面设有网格式铜层。所述连接段211与所述弯折段213连接处的两侧向所述连接段211内设有缓冲槽212(请参阅图3)。本实施例中，采用弯折段213表面采用网格式铜层设计取代镀EMI油墨，对所述弯折段213进行软化处理，避免弯折段213在弯折时断裂，同时所述连接段211与所述弯折段213连接处设有缓冲槽212，可以缓解在弯折时对所述连接段211与弯折段213之间的应力，减小折断的概率。
进一步的，所述延伸段215远离所述弯折段213的端部设有连接件216，用于电连接所述电路板15。本实施例中，所述连接件216为金手指。在其它实施例中，可以是电连接器。相应的，所述电路板15上设有与所述连接件216电连接的导电结构。
进一步的，所述连接件216上设有接地引脚(图未示)，用于实现所述柔性电路板21接地。即在所述金手指中选择一个金属片(接地引脚)进行接地设计，实现柔性电路板的接地。
进一步的，所述延伸段215上背向所述电池槽13的表面设有第一定位线217，用于定位所述柔性电路板21相对电路板15插接位置。所述所述延伸段两侧设有定位缺口218。所述弯折段213与所述延伸段215连接处的表面设有第二定位线219，用于定位所述弯折段213相对开孔112的位置。本实施例中，所述第一定位线217为两条且间隔设置。
请一并参阅图3、图4及图5，本实施例中，在电子装置进行组装时，先将本体防御夹具内，所述电池30预装于所述电池槽13内，然后通过机械手贴装所述显示屏模组20于容纳槽11内，其中所述柔性电路板21穿过开孔112位于电池30露出电池槽13的表面上，然后使用夹具(图未示)对所述柔性电路板与电池30对位组装，此时，根据所述第二定位线219定位对所述柔性电路板21的拉伸，即保证弯折段213恰好在开孔位置，避免在拉扯柔性电路板21时将弯折段拉出开孔。通过第一定位线217及定位缺口218与夹具定位来确定所述延伸段215与电路板插接对准，防止延伸段215向两侧偏移。在此过程中，因为柔性电路板21位于电池外侧而不是位于电池与电池槽之间，并且是先安装的电池，不会对显示屏模组20及柔性电路板产生抵压，避免对收容显示屏模组的容纳槽产生压合力而造成本体的弯曲变形，保证容纳槽的平整度。
进一步的，所述延伸段215朝向所述电池30的表面与电池30之间通过双面胶固定，防止所述柔性线路板21相对电池产生位移。
进一步的，所述壳体40朝向所述电池30的表面设有缓冲垫41，所述缓冲垫41抵持所述柔性电路板21及电池30，防止在电子装置振动时电池的缓动，保证电池电源的供给，同时可以进一步定位柔性电路板。本实施例中的缓冲垫41为泡棉。
进一步的，所述延伸段215朝向所述电池30的表面设有两个间隔设置的 导电层(图未示)。所述导电层为导电胶或者导电泡棉，本实施例中为导电泡棉。所述导电层被壳体压紧可以进一步对所述柔性电路板21固定，同时可以实现柔性电路板21接地的作用。
进一步的，所述显示屏模组20包括ESR反射膜(图未示)，所述ESR(Enhanced Specular Reflector反射片)反射膜厚度为0.089mm，并且所述ESR反射膜与所述连接段相对的表面设有缓冲层(图未示)，此结构可防止柔性电路板挤压ESR反射膜影响其功能。
本发明的电子装置的显示屏模组的柔性电路板21位于电池与壳体之间外侧而不是位于电池与电池槽之间，不会因为电池的压合力对显示屏模组20的容纳槽及柔性电路板产生抵压，避免对容纳槽产生压合力而造成本体的弯曲变形，保证本体的平整度。
以上所述是本发明的优选实施方式，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的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
