本实施例中，电池腔装置100还包括：PCB控制板110，所述PCB控制板110固定设置于所述壳体100a，且电连接电池包101，用以控制电池包101的过流保护、电子报警等。
具体的，PCB控制板110通过L形固定板109固定设置于所述壳体100a。如图3所示，L形固定板109包括固定连接的第一面板109a和第二面板109b。其中，第一面板109a用于固定设置在壳体100a的底部，第二面板109b用于固定设置在壳体100a的外侧壁，PCB控制板110固定设置于所述第二面板109b。
进一步的，第二面板109b背向所述壳体100a的面上具有平行设置的两条滑轨11，PCB控制板110设置于两条滑轨11之间。
另外，第二面板109b背向所述壳体100a的面上还设有第一突出部12，与设置在壳体100a外侧壁上的第二突出部13相对设置，PCB控制板110被卡设在第一突出部12、第二突出部13之间，以实现PCB控制板110的固定。
参照图2、图3，第一面板109a螺接固定于所述壳体100a的底部。具体的，壳体100a的底部设有螺丝柱120，螺丝柱120设有内螺纹，第一面板109a上具有与所述螺丝柱120对应的螺丝孔119，自攻螺丝111穿过所述螺丝孔119，并与螺丝柱120相配合固定，从而将第一面板109a固定至壳体100a的底部。
其中，螺丝柱120、螺丝孔119和自攻螺丝111均可以设置多个，且螺丝柱120、螺丝孔119和自攻螺丝111均一一对应设置。
第二面板109b插接固定于所述壳体100a的外侧壁。具体的，第二突出部13具有面向第二面板109b的插槽14，第二面板109b的一部分插设于所述插槽14中。也就是说，L形固定板109的一部分螺接固定于壳体100a的底部，另一部分插接固定于壳体100a的外侧壁，从而使L形固定板109能够牢牢固定在壳体100a上。
继续参照图3，电池腔装置100还包括：调速开关104，所述调速开关104固定设置于所述壳体100a，与电池包101电连接，用以控制固定设置在动力头内的电机的转速。

因此，当动力头被收纳、无需工作时，可以将保险丝钥匙102从钥匙孔内拔出，防止将动力头意外开启，引发事故；当需要动力头进行工作时，再将保险丝钥匙102插设在钥匙孔内，以接通电源。

当需要将电池包101设置在电池腔105中时，滑轨结构114能够引导电池包101，使电池包101顺利的放入至电池腔105，并引导电池包101与电池插座107相配合连接。
因此，能够防止电池包101在放入电池腔105的过程中，因为晃动，使电池包101与电池插座107无法较好的对接，而损坏电池包101、电池插座107上的插接元件。
继续参照图3，结合图5，电池腔装置100还包括：弹簧钢丝108，所述弹簧钢丝108的一端固定设置于壳体100a，另一端设置于所述 电池腔105内(图10所示)。
具体的，弹簧钢丝108包括：固定部108a和形变部108b，壳体100a外侧壁上设有卡槽118，壳体100a的底部设有通孔115(图4所示)；固定部108a固定卡设在卡槽118内，形变部108b通过通孔115伸入至电池腔105内，用于发生弹性形变。
当电池包101***至电池腔105内时，电池包101的底部与弹簧钢丝108接触，并压缩弹簧钢丝108；直至电池包101完全放入至电池腔105中，固定设置于壳体100a内侧壁的电池包按钮组件103能够卡住电池包101，从而防止电池包101弹出。
此时，弹簧钢丝108被压缩至最大程度，并对电池包101施加沿电池腔105轴向的弹性力。若按压电池包按钮组件103，使电池包101不再被电池包按钮组件103所限制，则弹簧钢丝108的弹性力能够将电池包101弹出电池腔105，实现电池包的自动拆卸。
参照图1、图2，壳体100a相对设置的两个外侧壁上分别设有固定柱121，所述固定柱121沿相反的方向延伸，用于将所述电池腔装置100固定至动力头的机壳上。
本实施例中，PCB控制板110、调速开关104、保险丝钥匙102、电池插座107和弹簧钢丝108均集成于电池腔装置100。也就是说，在将电池腔装置100固定设置于动力头之前，可以将PCB控制板110、调速开关104、保险丝钥匙102、电池插座107和弹簧钢丝108均分别与电池腔装置的壳体100a相固定。
如此设置，使得将电池腔装置100在固定至机壳201之前，电池腔装置100能够作为一个单独的组件进行单独装配，从而能够使以上相关元件充分整合和集中，简化装配程序，降低装配成本。而且，在组装动力头的过程中，以上相关元件无需与动力头的机壳进行安装固定，进一步提高装配效率、降低生产成本。
另外，由于以上相关元件无需与动力头的机壳相固定。因此，不 会使动力头的机壳内部结构变得十分复杂，使机壳更容易加工制造，并且不会使安装后的动力头显得凌乱。同时，电池腔装置100可以作为一个标准件，适用于不同的动力头，进一步减少生产制造成本。
参照图3，结合图8，电池腔装置100的装配过程如下：
提供电池腔装置的壳体100a和弹簧钢丝108，使弹簧钢丝的形变部108b通过通孔115***至电池腔105内；弹簧钢丝的固定部108a位于壳体100a外，并卡设在壳体外侧壁的卡槽118内。
提供PCB控制板110和L型固定板109，将PCB控制板110安装至L型固定板109的两条滑轨11之间，同时，将电池插座107固定设置在壳体100a的底部。
将L型固定板109固定安装至壳体100a。此时，第二面板109b插接固定于壳体外侧壁的插槽14内；第一面板109a通过自攻螺丝111固定至壳体100a的底部，在此过程中，电池插座107被第一面板109a固定至壳体100a的底部。
另外，第二面板109b能够完全覆盖住弹簧钢丝的固定部108a，以避免固定部108a脱离卡槽118。同时，PCB控制板110被卡设在第二面板的第一突出部12和壳体外侧壁的第二突出部13之间，实现PCB控制板110的固定。
将保险丝钥匙102***至钥匙座112上，且将插接端子106固定至保险丝钥匙的***部102a上，以防止保险丝钥匙102脱离钥匙座112。
将调速开关104压入至开关扣槽113内。
将电池包按钮组件103固定设置在壳体100a上。
当电池腔装置100安装完成后，可以将电池包101***至电池腔105，对电池腔装置100进行供电。
如图9至图11所示，示出了本实施例电池腔装置的正视图和剖 视图，其目的在于以使技术人员能够更好的理解本技术方案。
参照图12、图13，本实施例还提供一种动力头400，包括上罩壳组件200，上罩壳组件200包括相对设置的两个机壳202以及固定设置在机壳202上的上盖204，电池腔装置100固定设置在两个机壳202所围成的空腔内。
参照图14，动力头400还包括下罩壳组件300，下罩壳组件300包括底座301和电机302，所述底座301可拆卸的连接所述机壳202，所述电机302固定设置于底座301所围成的空腔内，且电机302电连接电池腔装置100。另外，电机302可选为无刷电机。
机壳202与底座301通过自攻螺丝连接，通过旋拧自攻螺丝，能够快速的拆卸机壳202和底座301，方便动力头400的维修。
此外，动力头400还设有外置电源线2，电源线2用于电连接外置控制手柄(图中未示出)与电池包101、电机302等，以使得控制手柄能够控制动力头400运行。
继续参照图12，所述电池腔装置100的中心轴线与所述机壳201的底面之间形成锐角α。也即是说，电池腔装置100倾斜设置，与水平面之间形成锐角，相较于电池腔装置100垂直设置的情形，能够降低动力头400的整体高度，从而降低动力头400的重心，保证动力头400的稳定，不易发生倾倒。
进一步的，使电池腔装置100与电机302错开排布，还能够节省动力头400的内部空间，进一步降低动力头的高度，节省装箱成本。
具体的，锐角α的角度范围在30°-60°之间，可选为55°，以使电池包101能够从电池腔装置100中更容易的安装和拆卸。
参照图12，结合图15，动力头400还包括透明盖201，透明盖设置于所述机壳202的顶部。通过设置透明盖201，能够使操作工人轻易的看到电池包上的品牌LOGO，有利于电池包厂商的品牌宣传。
具体的，机壳202上固定设有强力磁铁203，透明盖201上固定设有导磁元件，通过强力磁铁203的吸引力，使得透明盖201固定盖合在所述机壳202上。
如前所述，壳体100a相对设置的两个外侧壁上分别设有固定柱121；本实施例中，机壳202上设有固定孔211(图13所示)，固定孔211与固定柱121对应设置，通过将固定柱121***至对应的固定孔211内，以实现将电池腔装置100固定至机壳202。
需要说明的是，机壳202上可以设置多种类型的固定孔，以满足不同电池腔装置的安装要求；机壳202上还可以设置多个固定孔，使电池腔装置上的固定柱与不同的固定孔相配合，从而使电池腔装置具有不同的倾斜角度。
继续参照图12，动力头400包括两个电池腔装置100，两个电池腔装置100中能够分别设置电池包。具体的，两个电池包能够同时作为电源为动力头提供电能；或者，仅其中一个电池包作为电源为动力头提供电能。因而能够延长动力头400的工作时间。
需要说明的是，此时，可以在两个电池腔装置100上分别设置PCB控制板110，也可以仅在其中一个电池腔装置100上设置PCB控制板110(此时两个电池装置100的控制集成在一个PCB控制板上)，用以实现控制电机的过流保护、电子报警等功能。
在其他变形例中，动力头400中还可以设置三个以上的电池腔装置，并不影响本技术方案的实施。另外，本实施例的动力头400可以单独作为动力源购买，也可以作为进行整机出售。
参照图16，动力头400的安装方式如下：
将两个机壳202与上盖204固定安装形成上罩壳组件200。其中，在固定安装机壳202的过程中，将电池腔装置100固定设置在机壳202所围成的空腔内。将电机302固定安装至底座301内，形成下罩壳组件300。采用自攻螺丝将上罩壳组件200与下罩壳组件300固定 连接形成动力头400。
本实施例还提供一种割草机，包括以上所述的动力头，动力头中电机的输出端可以连接切割组件，以实现自动切割而除草；动力头中电机的输出端也可以连接自走带轮机构，以控制割草机滚轮的旋转，从而控制割草机前进或者后退。
第二实施例
参照图17、图18，一种电源线固定装置，包括动力头(图中未示出)和电源线压盖1。其中，动力头具有外壳4，外壳4上设有通孔10，设置于动力头内部的内部连接线5可以从通孔10中导出；所述电源线压盖1固定盖合于通孔10，并与外壳4围成容纳腔aa，所述容纳腔aa用于容纳电源线2的接头。也就是说，电源线2与内部连接线5的接头均能够设置在容纳腔aa中并电连接。
内部连接线5通常电连接动力头内部的电池腔装置与电机等执行部件，以控制电机等执行部件的运行。设置在外部的电源线2通常电连接控制手柄(图中未示出)，使电源线2与内部连接线5电连接，从而可以通过控制手柄控制电机等执行部件的运行。
相较于现有技术，本实施例的电源线2与内部连接线5的接头均设置在容纳腔aa中并电连接。当需要对电源线2进行拆装或者维修时，只需打开电源线压盖1，而不必拆卸动力头的外壳4，从而方便电源线2的拆装和维修。
需要说明的是，本实施例中动力头的外壳4可以是第一实施例中所述的机壳202，也可以是所述的底座301。
继续参照图18，电源线2的接头压接有两个公端子3，内部连接线5的接头压接有两个母端子6。容纳腔aa中还设有两个端子套7，端子套7用于套设在公端子3和母端子6的***，以连接内部连接线5和电源线2，实现内部连接线5、电源线2之间的电连接。
将端子套7套设在公端子3和母端子6***的方式十分方便，直接将公端子3和母端子6均***至端子套7即可。具体的，公端子3和母端子6均为金属铜端子，端子套7为塑料端子。
通过利用公端子3、母端子6和端子套7连接内部连接线5和电源线2，使得内部连接线5和电源线2之间的连接变得十分可靠，尤其在需要拆装电源线2时，能够实现快速拆装，方便快捷。进一步的，端子套7能够隔绝公端子3、母端子6与外部空间，从而起到较好的绝缘效果。
参照图19、图20和图21，电源线压盖1面向外壳4的壁面上设有卡扣腔8，所述端子套7固定设置于所述卡扣腔8。因此，端子套7能够被卡扣腔8所固定，从而更好地连接公端子3和母端子6，防止在运动过程中，公端子3或母端子6脱离端子套7，致使内部连接线5和电源线2之间电连接失效。
具体的，如图22所示，在电源线压盖1面向外壳4的壁面上还设有钩子9，当端子套7设置于卡扣腔8内时，钩子9对端子套7施加朝向电源线压盖1的作用力，使端子套7紧紧贴合于电源线压盖1，防止端子套7脱离卡扣腔8。另外，在卡扣腔8的上下两端也具有阻挡件，用于阻挡端子套7，防止端子套从卡扣腔8中滑出。
本实施例中，在装配或拆卸公端子3、母端子6的过程中，以及将端子套7固定至卡扣腔8的过程中，均不需要借助其他工具，而可以手工操作，方便快捷。
另外，在将电源线压盖1固定安装至外壳4之前，可以率先将端子套7固定设置在卡扣腔8中，从而能够方便端子套7的固定，且使端子套7与电源线压盖1之间的固定连接更为可靠。在端子套7固定设置在卡扣腔8中后，将公端子3、母端子6固定至端子套7中，方便内部连接线5与电源线2的连接，也使压盖1能够较为方便固定安装至外壳4。
参照图23至图28，电源线压盖1具有第一筋板12a，电源线压盖1面向外壳4的壁面上还设有弧形沟槽面11a，所述外壳4设有与弧形沟槽面11a相对设置的第二筋板13a(图27所示)，所述弧形沟槽面11a与第二筋板13a之间形成供所述电源线2穿过的通道，所述通道为S型迷宫通道。
可选的，弧形沟槽面11a与第二筋板13a之间形成的通道的大小适配于电源线2的外径。也就是说，当电源线2穿过上述通道时，第一筋板12a与第二筋板13a会挤压电源线2的外层绝缘皮，从而能够起到密封的作用，防止外界水滴等通过所述通道进入容纳腔aa中，造成公端子3和母端子6之间的接触不良。
另外，由于第一筋板12a、第二筋板13a对电源线2的挤压，使得电源线2能够被固定，电源线2不会松动，满足安规中，电源线拉拔力的要求。
进一步的，在电源线外层绝缘皮的内部可以增加棉纱，使得电源线2在所述通道中弯曲时能够有效保护电源线2的外层绝缘皮，减小磨损；还可以增加所述通道的圆角，以减小磨损。
参照图26，电源线压盖1还具有朝向下方的第一突出部16a，第一突出部16a的侧面与第二筋板13a贴合，使得第二筋板13a沿竖直方向被卡设于所述电源线压盖1。
参照图18和图19，所述外壳4面向电源线压盖1的壁面上设有压盖轮廓孔(图中未示出)，所述电源线压盖1具有与所述压盖轮廓孔相配合的第二突出部17a，所述第二突出部17a卡设于所述压盖轮廓孔。通过第一突出部16a、第二突出部17a从而将电源线压盖1牢牢的固定至外壳4。
也就是说，将电源线压盖1固定安装至外壳4，无需借助其他工具，通过按压电源线压盖1，使电源线压盖1在略微变形后，最终能够卡设在外壳4上，实现固定。
本实施例中，所述电源线压盖1还具有沿周向的外部轮廓边缘18a(图19所示)，所述外壳4具有与所述外部轮廓边缘相对设置的翻边结构19a(图18所示)，所述外部轮廓边缘18a与所述翻边结构19a贴合设置。
使外部轮廓边缘18a与翻边结构19a贴合设置，能够防止外部雨水进入容纳腔aa中，实现防水的要求，避免造成公端子3和母端子6之间的接触不良。
继续参照图19，电源线压盖1的两侧还设有防水板20a。当电源线压盖1固定安装至外壳4上时，防水板20a与外壳4的内周面贴合，进一步起到防水的技术效果。
参照图27，本实施例中，在外壳4的底部还设有漏水孔14a，当雨水进入容纳腔aa中时，位于容纳腔aa中的积水能够从漏水孔14a中流出至外界。避免由于容纳腔aa中内部积水过多，弄湿公端子3和母端子6，导致公端子3、母端子6之间接触不良。
综上，本技术方案一共采用的四重防水措施：
其一，使弧形沟槽面11a与第二筋板13a之间形成的通道挤压电源线2，从而起到密封的作用，防止外界水滴等进入容纳腔aa中；其二，使外部轮廓边缘18a与翻边结构19a贴合设置，从而防止外部雨水等进入容纳腔aa中；其三，使防水板20a与外壳4的内周面贴合，进一步起到防水的技术效果；其四，通过设置漏水孔14a以避免弄湿公端子3和母端子6，导致公端子3、母端子6之间接触不良。
参照图29至图31，将电源线压盖1固定至外壳4的方式如下：
提供电源线压盖1和端子套7，将端子套7固定至电源线压盖1的卡扣腔8中。使内部连接线5穿过外壳的通孔10，内部连接线5的接头压接有母端子6，母端子6位于外壳4的外部，并将母端子6***至端子套7中。电源线2的接头压接有公端子3，并将公端子3***至端子套7中，实现内部连接线5与电源线2之间的连接。
此外，也可以先将母端子6、公端子3分别***至端子套7实现电连接，之后再将端子套7固定至电源线压盖1的卡扣腔8中。
在内部连接线5与电源线2之间的连接之后，将电源线压盖1固定按压扣合至外壳4上，实现电源线压盖1与外壳4之间的固定。
参照图32、图33，本实施例中，电源线压盖1背向外壳的面上还具有缺口15a，缺口15a与第二突出部17a背对设置。
当需要将电源线压盖1从外壳4上拆卸时，只要用一个一字螺丝批头的前端扁身末端往下压所述缺口15a，缺口受到挤压发生弹性形变，使得第二突出部17a能够脱离压盖轮廓孔，从而实现电源线压盖1的快速拆卸。
虽然本发明披露如上，但本发明并非限定于此。任何本领域技术人员，在不脱离本发明的精神和范围内，均可作各种更动与修改，因此本发明的保护范围应当以权利要求所限定的范围为准。
