本发明的实施方式
[0090] 以下将结合附图所示的实施方式对本发明进行详细描述。 但这些实施方式并不 限制本发明， 本领域的普通技术人员根据这些实施方式所做出的结构或功能上 的变换均包含在本发明的保护范围内。 [0091] 实施例一
[0092] 本实施例以打草机为例进行具体说明。 参照图 1所示， 打草机 100包括连杆组件 13、 连接在连杆组件 13前端的工作机构 11和连接在连杆组件 13后端的动力机构 1 2。 这里的前后端以操作打草机时接近待切割区域为前， 用户手持或远离切割区 域为后， 如图中箭头所示的方向为前。 本实施例中， 工作机构 11包括外壳、 设 置于外壳内在工作平面内绕一轴线旋转的切割件， 以及连接于外壳上或连杆组 件上的护罩。 本实施例中的打草机， 包括设置在动力机构 12内的汽油发动机， 汽油发动机为工作机构 11提供动力。 在动力机构 12内还设有起动电机， 用以实 现汽油发动机的电起动。 在一些文献中， "起动电机" "电起动"也被称为"启动电 机""电启动"。
[0093] 在其它园林工具中， 工作机构的切割件也可以是直线往复移动、 旋转运动或者 通过交错的刀片横向运动来进行剪切动作， 当然也可以是其它不执行切割工作 的机构， 如吹吸机。 动力机构 12包括汽油机,汽油机包括电起动系统， 通过汽油 机提供动力以使打草机的动力强劲， 能够长时间在户外使用。 当然， 动力机构 也可以是电机以及给电机供电的可充电电池包或交流电源。
[0094] 在本实施例中， 连杆组件 13设置有电池包 50， 电池包 50的作用主要是给电起动 系统的起动电机供电， 仅在起动汽油发动机时放电。 进一步地， 电池包 50还可 以给汽油机的电控系统， 例如电子点火系统、 电子喷油系统、 电动油门系统、 自动风门系统等进行供电。 再进一步地， 在汽油发动机工作时， 可以给电池包 充电。
[0095] 本实施例中， 连杆组件 13上还设有两个手柄， 与连杆组件 13大致同一方向延伸 的手柄组件 20以及位于手柄组件 20之前的辅助手柄 14， 辅助手柄 14可以活动连 接于连杆组件 13以方便进行位置调节。 而动力机构 12设置在手柄组件 20的后端 ， 即手柄组件 20设置于辅助手柄 14和动力机构 12之间， 用户操作时握持更加稳 定。 另外， 连杆组件 13包括伸缩连杆， 通过调节伸缩连杆， 可以调节手柄组件 2 0和工作机构 11之间的距离。
[0096] 参照图 2到图 9所示， 手柄组件 20大致沿前后方向延伸， 包括前部机械连接口 20 2和后部机械连接口 203， 前部机械连接口 202连接连杆组件 13， 后部机械连接口 203直接或间接地连接动力机构 12。 前部机械连接口 202和后部机械连接口 203均 构造为圆孔， 且两个连接口的中心线共线， 如图 2和图 3中的轴线 X， 因此手柄组 件 20的延伸方向与连杆组件 13的延伸方向一致， 方便连杆组件 13穿过两个连接 口以简化手柄组件 20和连杆组件 13的组装。 手柄组件 20的后部构造为握持部 21 ， 握持部 21沿前后方向延伸预设长度， 握持部 21上还设有手柄包胶 211， 方便用 户握持。 手柄组件 20的前部上方包括操作部 22， 手柄组件 20的前部下方包括电 池安装部 30。 手柄组件 20的前后分别连接连杆组件 13和动力机构 12， 通过操作 部 22能够实现对动力机构 12和连杆组件 13前端的工作机构 11进行控制。 具体的 ， 操作部 22设有若干按键， 如伸出到握持部 21上端的油门锁定键 222， 伸出到握 持部 21下端的油门键 221， 并列的设置于操作部 21的壳体外部的点火键 225和熄 火键 220， 位于点火键 225和熄火键 220—侧且位置低于点火键 225和熄火键 220的 总开关键 224等等。 也就是说， 沿着连杆组件 13的延伸方向， 操作部 22至少部分 设置在连杆组件的上侧。
[0097] 手柄组件 20包括哈夫 （Half) 结构的壳体 201， 即壳体 201由大致对称的左右壳 体组装而成， 操作部 22设置在壳体 201的上部， 电池安装部 30设置于壳体 201的 下部， 且位于操作部 22的斜下方， 用于安装电池包 50， 电池包 50用于给电起动 系统供电， 电池包 50还可以给电子点火系统、 电子喷油系统等供电。 电池安装 部 30包括电池包安装结构， 其包括用于安装电池包 50的腔体 35以及设置于腔体 3 5上方的控制板单元， 沿着连杆组件 13的延伸方向， 腔体 35和控制板单元均设置 在连杆组件的下侧， 且控制板单元比腔体更靠近连杆组件 13。 控制板单元具有 控制起动电机、 电池保护等功能。 其中腔体 35设置于手柄组件 20的壳体 201上， 控制板单元卡设于壳体 201内， 控制板单元包括基板 31、 设置在基板 31上表面的 电子元件和设置在基板 31下表面的电极架 32， 电极架 32具有固定在基板 31的本 体 320a以及沿本体 320a两端向下延伸的卡脚 320b， 卡脚 320b伸入腔体 35内， 电池 包 50安装于腔体 35内与卡脚 320b配合实现与控制板单元的电连接。
[0098] 腔体 35的前方设有开口 350， 腔体 35可以分为与开口 350连通的前腔 350a以及相 对的后腔 350b， 卡脚 320b伸入后腔 350b内， 电池包 50安装时， 从开口 350插入前 腔 350a， 继而进入后腔 350b。 为了方便电池包 50的安装与拆卸， 前腔 350a具有沿 着与电池包 50安装方向垂直的方向连通外部的敞开部， 电池包 50安装于腔体 35 内， 电池包 50的侧壁的一部分自敞开部露出。 在本实施例中具体为腔体 35左、 右侧壁的前部无实体侧壁， 使电池包 50的左右侧壁的前端在安装或者拆卸状态 时容易被握持。 另外， 电池包 50的左右侧壁的前端还可以设置包胶 525， 方便握 持的同时也可以防止电池包 50被意外碰撞。
[0099] 参照图 6和图 8， 电极架 32的本体两端的卡脚 320b对应的设有向腔体内部突出的 卡脚第一端子 321和卡脚第二端子 322， 电池包 50上设有分别与卡脚第一端子 321 和卡脚第二端子 322配合的电池第一端子 521和电池第二端子 522， 电池第一端子 521和电池第二端子 522构造为电池包 50的正负极， 其分别设置于电池包 50端部 的两侧， 因卡脚第一端子 321和卡脚第二端子 322通过本体 320a连接于基板 31， 电 池包 50安装于腔体 35内时卡脚第一端子 321与电池第一端子 521电连接、 卡脚第 二端子 322和电池第二端子 522电连接， 从而实现电池包 50与控制板单元之间的 电连接。
[0100] 进一步的， 如图 5和图 8所示， 腔体 35左、 右侧壁分别设有向腔体 35内突出的导 向凸起 351、 352, 电池包 50的左右两侧对应设有导向槽 526， 电池包通过导向槽 526与导向凸起 351、 352的配合导向安装入腔体 35内， 其中两侧的导向槽 526分 别与电池第一端子 521和电池第二端子 522位置对应以实现电池包 50的安装更加 可靠。 另外， 电池包 50包括组装到一起的上盖 51和下盖 52以及位于上盖 51和下 盖 52内的电芯 53， 上盖 51上设置有充电口 511， 下盖 52上对应有充电电极 512， 通过充放电分别设置， 以利于充电接口标准化， 使充电更加方便。
[0101] 参照图 8并配合图 1和图 3所示， 电芯 53的设置方向与手柄组件的延伸方向一致 ， 也就是说电芯 53的轴线与手柄组件的延伸方向或连杆组件的延伸方向大致平 行， 电芯 53包括至少两个， 在本实施例中， 电芯 53为两个 3.6V电芯。 并且至少 两个电芯 53沿手柄组件的侧向排布， 这里以用户握持手柄组件操作时朝向工作 表面的一侧为下， 另一侧为上， 垂直于上下和手柄组件的延伸方向的为侧向， 因此电池包 50在上下方向上具有较薄的厚度 （约一个电芯的直径） ， 也就是说 ， 电池包 50在上下方向的尺寸小于其在侧向方向的尺寸。 而且电池第一端子 521 和电池第二端子 522分别设置于电池包的两侧， 使电池包及其安装结构更薄， 以 减小手柄组件的整体体积。 在本实施例中， 腔体 35的后壁设有腔体第三端子 323 ， 对应的电池包 50临近电池第一端子 521和电池第二端子 522的端部设有与腔体 第三端子 323配合的电池第三端子 523， 控制板单元通过腔体第三端子 323和电池 第三端子 523连接电池包 50内的检测模块， 比如电池包 50内的测温模块。 另外， 腔体 35的下壁设有第三导向凸起 353， 对应的电池包 50的下部设有与第三导向凸 起 353配合的第三槽部 （图未示） ， 第三导向凸起 353沿着电池包 50的安装方向 与腔体第三端子 323的位置对应， 相应的第三槽部与电池第三端子 523的位置也 对应， 从而方便电池包 50安装时腔体第三端子 323与电池第三端子 523的可靠连 接。
[0102] 参照图 10到图 14所示， 为了实现电池包在腔体内的锁定， 电池包安装结构还包 括操作机构， 操作机构设置在腔体 35下部， 操作机构包括操作键 60以及抵压操 作键 60的复位件 65， 电池包 50上设有与操作键 60配合的槽部 55， 操作键 60在复 位件 65的作用下卡接槽部 55将电池包 50锁定在腔体 35内。 具体的， 操作键 60包 括与槽部 55卡接的勾部 62、 远离勾部 62的按压部 61以及位于勾部 62和按压部 61 之间的转轴 63， 复位件 65向外抵压按压部 61， 在转轴 65的作用下， 勾部 61向内 与槽部 55保持卡接， 从而使电池包 50相对于腔体 35被锁定。
[0103] 参照图 13和图 14所示， 当需要拆卸电池包 50时， 向内施力给按压部 61， 按压部 61克服复位件 65的作用力同时在转轴 63的作用下枢转带动勾部 62与槽部 55分离 ， 电池包 50相对于腔体 35解锁， 为了方便取出电池包， 在腔体 35的后壁设有弹 性件， 电池包 50安装于腔体内， 弹性件被压缩； 当电池包 50解锁， 弹性件的弹 力释放， 即在弹性件的作用下， 电池包 50被向腔体 35外弹出， 从而可以实现单 手拆卸电池包。 本实施例中优选的， 腔体第三端子 323和弹性件可以构造为同一 元件， 如弹簧， 从而方便组装， 以降低成本。 当然也可以根据实际需求将弹性 件和腔体第三端子 323分别设置。
[0104] 另外， 未安装电池包 50时， 勾部 62在复位件 65的作用下朝向腔体 35内突出， 为 实现单手安装电池包， 勾部 62朝向腔体 35开口 350的一面构造为导向面， 导向面 可以是斜面、 弧面或曲面等能够使电池包 50向腔体 35内移动的力产生向下的分 力的面， 随着电池包 50向腔体 35内移动， 勾部 62向外运动通过转轴 63带动按压 部 61克服复位件 65的作用， 电池包 50顺利安装入腔体 35， 当槽部 55与勾部 62位 置对应时， 勾部 62在复位件 65的作用下卡入槽部 55实现电池包 50的锁定。 本实 施例中， 复位件 65优选为压缩弹簧， 其一端抵接在壳体上， 另一端抵接按压部 。 当然， 压缩弹簧也可以设置为抵接勾部， 而且复位件也可以设置为扭簧， 扭 簧可以套设在转轴上， 一端相对于壳体固定， 另一端抵压按压部或者勾部。
[0105] 由上述说明可以看出， 本发明通过将电池包安装到控制板单元， 实现电池包相 对于基板的固定， 不会受到工具使用时振动的影响， 能够保护电池包以及控制 板单元， 防止因此而导致的工具故障无法使用， 而且该电池包安装结构紧凑， 还可以实现单手拆装电池包， 从而用户使用更加方便。 通过将电池包安装结构 设置于手柄组件， 而操作部也设置在手柄组件， 握持的同时可以进行工具的操 作， 而且将电池包、 控制板单元以及操作部设置在一起， 减少布线的麻烦， 组 装更加简便， 成本小同时使用可靠。 通过将手柄组件设置于工作机构和动力机 构之间， 能够保护电池包和控制板单元不受动力机构的振动和产生热量的影响 ， 而且手柄组件位于动力机构的前部， 并且安装的时候安装电池包的腔体的开 口朝向工作机构， 更加不会收到动力机构产生的废气的影响， 从而减小园林工 具因振动和受热引发的故障， 从而使用更加可靠并且园林工具的使用寿命更长
[0106] 本实施例以打草机为例进行说明， 当然也可以是其它园林工具， 如割灌机、 修 边机、 链锯、 修枝剪等园林工具。
[0107] 实施例二
[0108] 如图 15-图 36所示， 本实施例以电起动汽油吹吸机为例进行说明。 秋天户外往 往会有很多散落的落叶， 为家宅庭院的环境带来诸多问题， 尤其是下过雨之后 ， 树叶混杂着泥水贴在地面上， 给清扫带来很大的麻烦。 本实施例的电起动汽 油吹吸机是能够清扫庭院或周边环境的设备， 其工作原理是通过电池工作启动 汽油机的引擎， 引擎促使曲轴高速旋转并带动叶轮旋转， 从而产生吸风或吹风 ， 实现打扫的目的。
[0109] 具体地， 如图 15和图 16所示， 该吹吸机 700包括机体 701， 机体 701上设置有工 作机构和动力机构， 其中工作机构包括蜗壳 702和设置在蜗壳 702内的叶轮， 蜗 壳 702的一侧设置有进风口 703， 蜗壳 702的前部设置有出风口 704。 在本实施例 中， 吹吸机 700的工作机构包括为离心风机， 出风口 704的出风方向与进风口 703 的进风方向相垂直； 在其他实施例中， 吹吸机 700的工作机构还可为轴流风机， 则其出风口 704的出风方向与进风口 703的进风方向平行。 上述动力机构包括汽 油发动机和起动电机， 汽油发动机为工作机构提供动力， 起动电机用以实现汽 油发动机的电起动。 本实施例通过汽油发动机提供动力以使吹吸机的动力强劲 ， 能够长时间在户外使用； 当然， 动力机构也可以是电机以及给电机供电的可 充电电池包或交流电源等。 进一步地， 机体 701的上方还设置有手柄组件 20， 手 柄组件 20包括壳体， 壳体上设有握持部 21、 操作部 22和电池安装部， 其中握持 部 21沿出风的方向延伸， 握持部 21上还设有手柄包胶， 方便用户握持； 操作部 2 2位于握持部 21的前端， 操作部 22上设有用于激活吹吸机的激活开关 226和用于 启动吹吸机工作的启动开关 227; 电池安装部 30设置于壳体靠近出风口 704的一 端， 且位于操作部 22的斜下方， 电池安装部 30上可拆卸地安装有电池包 50， 电 池包 50用于为起动电机供电。 此外， 电池包 50还可以给汽油机的电控系统， 例 如电子点火系统、 电子喷油系统、 电动油门系统、 自动风门系统等进行供电。 再进一步地， 在汽油发动机工作时， 还可以给电池包 50充电。
[0110] 该吹吸机的起动过程如下： 电池包 50向起动电机提供直流电源， 起动电机高速 旋转带动机体 701内的齿轮组件转动， 齿轮组件不断地向机体 701内的涡簧施加 压力， 即涡簧不断地将起动电机的动能进行储存， 一旦涡簧提供的弹力大于机 体 701内曲轴的阻力， 涡簧将通过离合机构向曲轴释放能量， 由此促使曲轴的旋 转， 并实现汽油机的电起动过程。 一旦汽油机启动过后， 曲轴将高速旋转， 带 动叶轮进行工作， 同时离合机构将脱离， 使减速机构停止工作。
[0111] 需要说明的是， 本实施例所提供的手柄组件 20的具体结构与实施例一中的手柄 组件 20的结构相似， 其相同之处本实施例中将不再赘述， 下面仅以其不同之处 进行说明。
[0112] 本实施例中， 腔体 35和控制板单元均设置在出风口 704的上方， 且均位于操作 部 22的下方。 腔体 35设置于电池安装部 30内， 电池包 50能够沿握持部 21的延伸 方向插入腔体 35或从腔体 35中弹出。 然而， 现有的电池包安装结构在弹出时由 于没有缓冲， 若在电池包 50弹出的过程中用户不能及时握住电池包 50， 则容易 造成电池包 50跌落损坏， 为此， 本实施例在电池包 50上设置了弹出缓冲结构， 能有效防止电池包一次性弹出。 具体地， 如图 17-图 19所示， 本实施例将槽部 55 设置为第一槽 551和第二槽 552， 其中第一槽 551相对远离电池第三端子 523， 第 二槽 552相对靠近电池第三端子 523， 且第一槽 551和第二槽 552均能与勾部相配 合。 这里， 第一槽 551的深度大于第二槽 552的深度， 当勾部 62卡入第一槽 551时 ， 能使电池包 50相对于腔体 35锁定， 此时电池包 50不能从腔体 35内抽出； 当电 池包 50相对于腔体 35解锁时， 电池包 50向腔体 35外弹出， 此时勾部 62能卡入第 二槽， 电池包 50可被用户手动抽出。
[0113] 进一步地， 如图 20所示， 第一槽 551远离电池包 50的伸出端的侧壁为平面， 该 侧壁与电池包 50的顶侧面 507之间的夹角 α不大于 90°， 或者该侧壁为曲面， 则该 侧壁的切面与电池包 50的顶侧面 507之间的最小夹角不大于 90° ; 该设置能够保证 勾部 62与第一槽 551的卡紧连接， 防止电池包滑脱； 示例性的， 如图 20， 可将第 一槽 551的前部与电池包顶侧面 507的角度设置为一锐角， 将第一槽 551的后部与 电池包顶侧面 507的角度设置为一锐角。 第二槽 552远离电池包 50的伸出端的侧 壁为平面， 该侧壁与电池包 50的顶侧面 507之间的夹角 β不小于 120°， 或者该侧壁 为曲面， 则该侧壁的切面与电池包 50的顶侧面 507之间的最大夹角不小于 120°， 该设置一方面能使电池包 50卡在腔体 35内不会跌落， 另一方面又能使操作者通 过施加一定的作用下将电池包 50从腔体 35内抽出； 示例性的， 如图 20， 可将第 二槽 552的前部与电池包顶侧面 507的角度设置为一锐角， 将第二槽 552的后部与 电池包顶侧面 507的角度设置为一钝角。
[0114] 本实施例弹出缓冲结构的工作过程如下： 当需要拆卸电池包 50时， 向内施力给 按压部 61， 按压部 61克服复位件 65的作用力同时在转轴 63的作用下枢转带动勾 部 62与第一槽 551分离， 电池包 50相对于腔体 35解锁； 当电池包 50解锁， 腔体 35 后壁的弹性件弹力释放， 即在弹性件的作用下， 电池包 50被向腔体 35外弹出， 弹出的过程中电池包 50上的第二槽 552与勾部 62卡接， 防止电池包 50完全与腔体 35分离， 然后用户可人为地将电池包 50从腔体 35内抽出。
[0115] 进一步地， 由于电池包 50插入方向的特点， 在电池包 50插入腔体 35的过程中， 电池包 50的左右两侧会对卡脚第一端子 321和卡脚第二端子 322产生沿电池包 50 插入方向的力， 导致电极架 32容易发生松动， 同时， 在电池包 50多次插拔的过 程中， 也容易造成卡脚第一端子 321和卡脚第二端子 322与基板 31之间的焊点损 坏松脱。 为此， 本实施例还进一步对控制板单元及其安装结构进行了改进。 具 体如下：
[0116] 如图 21-图 26所示， 该控制板单元包括基板 31、 设置在基板 31上表面的电子元 件和设置在基板 31下表面的电极架 32， 电极架 32具有固定在基板 31的本体 320a以 及沿本体 320a两端向下延伸的卡脚 320b。 如图 22， 本实施例中电极架 32安装于壳 体 201内， 壳体 201内设置有凹部 34， 电极架 32的两个卡脚 320b均卡接于凹部 34 内， 从而能够进一步地防止在电池包 50插拔过程中电极架 32的晃动。 电极架 32 的两个卡脚 320b伸入腔体 35内， 一端的卡脚 320b上安装有卡脚第一端子 321， 另 一端的卡脚 320b上安装卡脚第二端子 322， 电池包 50安装于腔体 35内并与卡脚第 一端子 321和卡脚第二端子 322电连接。 进一步地， 本实施例的电极架 32为一体 式结构， 其中本体 320a与其两端的卡脚 320b形成" U"形状， 该设置一方面能够使 电池包 50上的电池第一端子 521和电池第二端子 522分别对应地与电极架 32两侧 的卡脚第一端子 321和卡脚第二端子 322紧密连接， 提高连接可靠性； 另一方面" U"形的结构还具有弹性的减震效果， 防止电池包 50在使用过程中由于振动而与 控制板单元断开连接。 同时上述一体式" U"形结构的设置还能以最少的材料满足 较好的安全性能需要， 因而也节省了材料成本。 优选地， 本实施例电极架 32采 用阻燃材料制作， 如塑料、 橡胶、 玻璃等， 以保证电极架 32具有良好的阻燃性 能。
[0117] 本实施例中， 卡脚第一端子 321和卡脚第二端子 322上分别设置有第一固定件 32 4， 本体 320a两端的卡脚 320b上分别设置有端子安装槽 33， 端子安装槽 33上设置 有第二固定件 325。 通过第一固定件 324与第二固定件 325的配合， 将卡脚第一端 子 321和卡脚第二端子 322牢牢固定于卡脚 320b上， 防止两个端子在电池包 50的 作用力下发生晃动。 优选地， 上述第一固定件 324为开设于卡脚第一端子 321和 卡脚第二端子 322底部的定位孔， 第二固定件 325为凸设于卡脚 320b内侧的定位 柱， 通过定位孔与定位柱的配合， 既保证了端子固定的可靠性， 同时也提高了 安装便捷性。 上述卡脚第一端子 321的上端设置有第一电极插片 3211， 卡脚第二 端子 322的上端设置有第二电极插片 3221， 电极架 32上与开设有供卡脚第一端子 321和卡脚第二端子 322穿过的通孔， 基板 31上在与卡脚第一端子 321和卡脚第二 端子 322相对应的位置开设有电极孔 311。 第一电极插片 3211和第二电极插片 322 1分别穿过相应的通孔及电极孔 311， 然后与基板 31焊接相连， 该设置提高了电 极插片的定位准确性。 为提高焊接强度， 本实施例第一电极插片 3211和第二电 极插片 3221的形状优选为鱼叉形， 鱼叉形的结构可通过两个叉脚与基板 31进行 两点焊接， 使电极插片与基板的焊接更牢靠。 卡脚第一端子 321的下端设有第一 触片 3212， 用于与电池第一端子 521抵接； 卡脚第二端子 322的下端设有第二触 片 3222， 用于与电池第二端子 522抵接。
[0118] 进一步地， 电极架 32的本体 320a与基板 31之间通过第三固定件 326固定连接， 本实施例优选第三固定件 326为铆钉， 基板 31和电极架 32上开设有用于穿设铆钉 的铆钉孔 326a。 铆接的连接方式保证了电极架 32与基板 31的牢固稳定连接。 进一 步地， 还可以在基板 31上设置基板定位孔 312， 在电极架 32的顶端设置基板定位 柱 312a， 以实现电极架 32与基板 31的定位， 保证安装的准确性。 本实施例通过基 板定位孔 312与基板定位柱 312a的配合实现基板 31与电机架 32的定位， 通过铆钉 与铆钉孔 326a的配合， 实现电极架 32与基板 31的固定， 通过铆钉和基板定位柱 31 2a的共同作用， 使电极架 32牢固地固定在基板 31上， 防止电池插拔过程中电极焊 点的松动。
[0119] 本实施例通过将卡脚第一端子 321和卡脚第二端子 322固定于电极架 32上， 将电 极架 32固定于基板 31上， 使得卡脚第一端子 321和卡脚第二端子 322即使在受到 电池包 50的冲击力时， 仍能保持相对位置的稳定定， 防止电极插片在电极孔 311 内晃动而导致焊点松脱。 进一步地， 本实施例腔体第三端子 323上设置有具有一 定柔性的导线部 3231， 腔体第三端子 323通过导线部 3231与基板 31连接， 导线部 3231能够吸收振动， 从而较好地解决了由于振动而导致腔体第三端子 323与基板 31焊点松动的问题。 此外腔体第三端子 323上还设置有弹簧部 3232， 该弹簧部 32 32既可作为电池包 50的弹出的功能构件， 同时又可作为信号传递的功能构件， 从而方便了设备的组装， 降低了制作成本。 [0120] 在本实施方式中， 如图 27〜图 36所示， 电池包 50的形状大致呈六面体， 包括相 对设置的电池包底侧面 508和电池包顶侧面 507、 相对设置的电池包前侧面 503和 电池包后侧面 504、 以及相对设置的电池包左侧面 505和电池包右侧面 506。 电池 包 50包括电池包外壳和安装在电池包外壳内的电芯 53。 具体地， 电池包外壳至 少由上盖 51和下盖 52扣合而成。 需要说明的是， 本实施例中底侧面 508设置于上 盖 51， 顶侧面 507设置于下盖 52。 电芯 53大致呈圆柱状， 电芯 53安装在电池包外 壳内， 其中， 两个电芯 53的轴向沿电池包 50的前后方向设置、 两个电芯 53的径 向沿电池包 50的左右方向设置， 且两个电芯 53沿电池包的左右方向并排排列 ( 即电芯 53的轴线与握持部 21的延伸方向一致， 两个电芯 53的排布方向与握持部 2 1的延伸方向垂直） ， 这种设置使电池包 50具有较小的在上下方向的厚度。 此外 ， 电池包外壳内位于电芯 50的后方还设有电池控制板 57。
[0121] 在本实施方式中， 参考图 34〜图 36， 电池包 50上设置有放电端口和充电端口 54 ， 放电端口具体为设置于电池包 50左右两侧的电池第一端子 521和电池第二端子 522, 电池第一端子 521和电池第二端子 522均靠近电池包 50的后部设置， 且分别 与电池控制板 57电连接。 采用上述设置形式， 一方面使电池第一端子 521和电池 第二端子 522分别位于电池包 50的两侧， 由于两者的距离很大， 难以在非故意的 情况下直接接触， 最大限度地防止电池第一端子 521和电池第二端子 522之间发 生短路； 另一方面， 由于电池控制板 57设置在电池包 50的后部， 所以电池第一 端子 521和电池第二端子 522可以直接从电池控制板 57的左右两端引出， 避免了 复杂的布线。 为了方便识别， 在电池包 50左侧面上、 电池第一端子 521附近设有 放电负极标记 521a; 在电池包 50右侧面上、 电池第二端子 522附近设有放电正极 标记 522a。 在其他实施方式中， 电池第一端子 521和电池第二端子 522的位置可根 据实际情况调换。
[0122] 在本实施方式中， 参考图 27、 图 30〜图 31， 充电端口 54设置在电池包 50的底侧 面 508。 充电端口 54包括分别于电池控制板 57电连接的充电负极端口 541和充电 正极端口 542。 其中， 充电负极端口 541和充电正极端口 542间隔设置， 且充电负 极端口 541的外轮廓与充电正极端口 542的外轮廓不相同。 与充电端口 54插接配 合的充电端子具备相应的间隔设置的充电正极端子和充电负极端子， 且充电正 极端子的外轮廓与充电负极端子的外轮廓不相同。 这种设计不仅可以防止正负 极插反， 而且能够有效地防止充电正极端口 542与充电负极端口 541之间发生短 路。 进一步地， 充电端口 54设于靠近电池包 50后侧面 504的位置， 这样设计使充 电端口 54靠近电池控制板 57， 避免了复杂的布线。
[0123] 进一步地， 电池包 50还设有分别与电池控制板 57电连接的至少一个温度传感器 56。 在本实施方式中， 温度传感器 56设置在两个电芯 53之间， 且与任意一个电 芯 53表面贴合。 在其他实施方式中， 可根据需要在每个电芯 53上均设置至少一 个温度传感器 56， 温度传感器 56通过导线与电池控制板 57连接。 电池包 50后侧 面 504设有电池第三端子 523， 由于电池第三端子 523与电池控制板 57的距离很近 ， 所以电池第三端子 523可以从电池控制板 57上直接引出， 避免了复杂的布线。 相应地， 在腔体 35的后侧内壁设有与电池第三端子 523配接的腔体第三端子 323
[0124] 当电池包 50插入腔体 35后， 电池第一端子 521和电池第二端子 522分别对应地与 卡脚第一端子 321和卡脚第二端子 322电连接， 使电池包 50通过控制板单元、 线 缆组件与起动电机电连接， 为起动电机及其他电子元器件供电； 电池第三端子 5 23通过腔体第三端子 323与控制板单元电连接， 控制板单元通过电池第三端子 52 3采集的温度信号， 直接地控制或通过电池控制板 57间接地控制电池包 50的工作 参数。
[0125] 在吹吸机中， 动力组件包括汽油发动机， 导致在工作时很难避免产生较大的振 动。 如果将电池包 50与腔体 35的配合间隙设计得很小， 虽然可以防止电池包 50 相对于腔体 35的晃动， 进而避免电池包放电端口的磨损， 然而会带来电池包 50 插拔困难的问题。 如果将电池包 50与腔体 35的配合间隙设计得不足够小， 虽然 可以保证插拔顺利， 但是电池包放电端口磨损会严重影响电池包 50的使用寿命
[0126] 鉴于上述原因， 在本实施例中电池包 50还包括弹性材料制成的减振件。 如图 27 -图 36所示， 为了吸收电池包 50在腔体 35内沿左右方向的振动， 在电池包 50左侧 面和电池包 50右侧面分别设置至少两个第一减振件 571 ; 为了吸收电池 50包在腔 体 35内沿上下方向的振动， 在电池包 50的顶侧面 507设置至少一个第二减振件 57 2。 具体地， 参考图 34、 图 35， 两个第一减振件 571对称地设置在电池包 50左侧 面和电池包 50右侧面。 以左侧的第一减振件 571为例， 第一减振件 571嵌在下盖 5 2的左侧面内， 其包括至少部分地凸出于下盖 52外表面的第一外端 571a， 还包括 至少部分地凸出于下盖 52内表面的第一内端 571b。 第一内端 571b的内端面抵靠 电芯 53 ; 当电池包 50装入腔体 35时， 第一外端 571a的外端面抵靠腔体 35内壁， 此 时第一减振件 571夹在腔体 35内壁和电芯 53之间。 进一步地， 第一外端 571a小于 第一内端 571b， 能够保证第一减振件 571不会从电池包 50上脱落。 更进一步地， 第一减振件 571与电池包 50前侧面 503之间的距离为 Dl， 第一减振件 571与电池包 50后侧面 504之间的距离为 D2， D1与 D2与相比大致相等， 可以将 D1/D2取值设在 1〜1.5之间， 优选的 D1/D2为 1.2〜1.3。
[0127] 参考图 28、 图 32和图 33， 至少一个第二减振件 572嵌在下盖 52内， 其包括至少 部分地凸出于下盖 52外表面的第二外端 572a， 还包括至少部分地凸出于下盖 52内 表面的第二内端 572b。 进一步地， 在第二内端 572b的内端面设有与电芯 53外表 面弧度相应的弧面。 弧面抵靠电芯 53 ; 当电池包 50装入腔体 35时， 第二外端 572a 的外端面抵靠腔体 35内壁， 此时第二减振件 572夹在腔体 35内壁和电芯 53之间。 进一步地， 第二外端 572a小于第二内端 572b， 能够保证第二减振件 572不会从电 池包 50上脱落。 更进一步地， 第二减振件 572设置在槽部 55与电池包 50后侧面 50 4之间。 在本实施方式中， 第二减振件 572设置为两个， 其弧面分别设置在两个 电芯 53的大致正下方。
[0128] 通过设置减振件， 本实施例在保证电池包 50插拔顺利的情况下， 有效减小了电 池包 50在工作过程中的振动， 防止电池包 50相对于腔体 35发生晃动， 进而避免 了电池包 50放电端口的磨损， 提高了电池包 50的使用寿命。
[0129] 本实施例以吹吸机为例进行说明， 当然本实施例以上所提供的手柄组件 20中电 池包 50的缓冲弹出结构， 电极架 32与基板 31、 卡脚第一端子 321、 卡脚第二端子 322、 腔体第三端子 323之间的连接结构， 电池包 50自身的结构， 电池包 50与腔 体 35的安装结构， 以及充电端口 54、 减振件、 温度传感器 56的具体设置等等， 同样也可用于实施例一中的打草机或其它的园林工具， 如割灌机、 修边机、 链 锯、 修枝剪等园林工具。 [0130] 应当理解， 虽然本说明书按照实施方式加以描述， 但并非每个实施方式仅包含 一个独立的技术方案， 说明书的这种叙述方式仅仅是为清楚起见， 本领域技术 人员应当将说明书作为一个整体， 各实施方式中的技术方案也可以经适当组合 ， 形成本领域技术人员可以理解的其他实施方式。
[0131] 上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说 明， 它们并非用以限制本发明的保护范围， 凡未脱离本发明技艺精神所作的等 效实施方式或变更均应包含在本发明的保护范围之内。
