为了方便说明本申请的技术方案,这里以骑乘式割草机为例,并定义了如图1所示的前侧、后侧、左侧、右侧、上侧和下侧。
如图1所示,骑乘式割草机100包括:主机架11、座椅12、动力输出组件13、行走组件14、操作组件15以及电源装置16。

动力输出组件13包括用于输出动力的以实现机械功能的输出件,例如在本实施例中,输出件可以为割草元件。动力输出组件13还连接至主机架11,在本实施例中,动力输出组件13可以安装至主机架11的下侧。动力输出组件13具还包括:第一马达以及底盘。割草元件用于实现割草功能,第一马达用于驱动割草元件高速旋转,底盘形成有用于至少容纳部分马达和部分割草元件的容纳空间。动力输出组件可以包括一个以上的割草元件,对应的,第一马达的数目可以与割草元件相对应。
行走组件14用于使得骑乘式割草机100能够在草坪上行走。行走组件14 可以包括:第一行走轮141、第二行走轮142,在沿前后方向上,第一行走轮141设置在第二行走轮142的前侧。在本实施例中,第一行走轮141的数目为2,第二行走轮142的数目也为2。其中,在沿第一直线101方向上,动力输出组件13至少部分设置在第一行走轮141和第二行走轮142之间,且在沿第一直线101方向上,座椅12也至少部分设置在第一行走轮141和第二行走轮142之间,这样使得整机的重心在第一直线101方向上位于第一行走轮141和第二行走轮142之间,从而提高整机的平衡性能。第一行走轮141可以为能以第一轴线102为轴转动的万向轮,第一行走轮141具有第一直径。行走组件14还包括用于驱动第二行走轮142以第二轴线为轴转动的第二马达,第二马达的数目也为2,这样,当这两个第二马达以不同的转速驱动对应的第二行走轮142转动时,这两个第二行走轮142之间产生速度差,从而使得骑乘式割草机100进行转向。第二行走轮142具有第二直径,第二行走轮142的第二直径大于第一行走轮141的第一直径。
操作组件15用于供用户操作以控制骑乘式割草机100行走以及输出动力。操作组件15可以包括:第一操作元件151和第二操作元件152。第一操作元件151用于供用户手动操作以启动马达,从而控制割草元件割草和控制骑乘式割草机100在草坪上行走,第二操作元件152用于供用户踩踏以控制割草机的运行状态。
如图2至图3所示,电源装置16用于给动力输出组件13和行走组件14供电。电源装置16设置在主机架11上并能从主机架11上拆卸下来。在一些实施例中,电源装置16设置在主机架11后方,电源装置16与设置在主机架11前部和中部的其他部件配合使得骑乘式割草机100整机的重心在第一直线101方向上位于第一行走轮141和第二行走轮142之间,从而使得骑乘式割草机100的重心更稳,使得骑乘式割草机100在经过较陡的上坡或下坡时,不至于倾覆。
如图4至图5所示,电源装置16通过一组支撑座17连接至主机架11上。支撑座17包括一个用于支撑电源装置16的支撑部171,同时还包括第一连接部172和第二连接部173。其中,第一连接部172用于连接电源装置16,第二连接部173用于连接至主机架11。第一连接部172通过连接件连接至电源装置16的底端;第二连接部173通过连接件连接至主机架11上。可选的,主机架11上还设置有连接机构111,连接机构111作为一个中间件设置在主机架11上,其一方面能能够保护主机架11的结构强度,另一方面能够保证电源装置16与主 机架11支架连接的稳定性。可以理解,主机架11上也可以不设置连接结构,而由第二连接部173直接连接至主机架11上。作为一种可选的实现方式,连接件均可以采用螺钉,第一连接部172和第二连接部173均可设置为螺钉孔。可以理解,第一连接部172和第二连接部173的设定方式,只要能将电源装置16可拆卸的连接至主机架11,并能保证稳定的连接关系即可。
骑乘式割草机在运行过程中,在经过较复杂的路况时,会产生较大震动,当这种震动传递至主机架11时,主机架11将震动传递至电池包161连接片时,易导致电池包161和电池包161连接片之间接触不良,从而产生不良打火的隐患。为了避免不良打火的存在,电源装置16本身设置有一定的缓冲功能,其能基本吸收来自主机架11的震动。为了使得电源装置16能适应较剧烈的震动,还在支撑座17与主机架11的连接处设置了缓冲件112。缓冲件112能极大的减小电源装置16与支撑座17之间的相对运动。在一些实施例中,缓冲件112设置在第二连接部173与主机架11之间,其能有效吸收来自主机架11的震动,避免来自主机架11的震动传递至电源装置16上。作为其他可选的实现方式,缓冲件112还能设置在电源装置16与主机架11之间的任意连接位置上,只要能将来自主机架11的震动吸收并避免其传递至电池包161即可。缓冲件112可以是弹性件1675、橡胶件及其他具备缓冲功能的元器件。当设置缓冲件112时,电源装置16本身所需要具备的缓冲功能将会大大地被削弱,通过这样的设置,电源装置16的结构将能实现简化,其装配要求也会降低。
如图6至图7所示,电源装置16包括电池包161和电池仓162,电池仓162形成有用于容纳电池包161的容纳空间。电池仓162包括有主仓室163、仓盖164。其中,主仓室163形成用于容纳电池包161的容纳空间,仓盖164与主仓室163构成转动连接,并能至少部分封闭主仓室163。在一些实施例中,仓盖164与主仓室163包括第一连接件165和第二连接件166。其中,第一连接件165设置在仓盖164和主仓室163的端部,仓盖164能绕第一连接件165转动。第二连接件166包括第一连接端166a和第二连接端166b,第一连接端166a设置在仓盖164的中部,第二连接端166b设置在主仓室163靠近第一连接件165的一端。第一连接端166a和第二连接端166b之间设置有一个气弹簧166c,气弹簧166c能围绕第一连接端166a和第二连接端166b转动。气弹簧166c内预充有气体,当掀开仓盖164至一个预设角度时,气弹簧166c会输出一个推力从而支撑仓盖164绕第一连接件165自动转动至完全敞开状态,此时可以拆卸或安装 电池包161。当盖下仓盖164至一个预设角度时,气弹簧166c会输出一个推力从而支撑仓盖164绕第一连接件165自动转动至完全闭合。事实上,第二连接件166具有一个无法输出的推力的止点,在用户打开或关闭仓盖164时,均需要手动推动仓盖164跨越该止点,气弹簧166c才能自动输出一个推力。
如图8至图13所示,作为一种实现方式,仓盖164上还设置有用于将仓盖164锁定至主仓室163的卡扣167。在一些实施例中,卡扣167包括操作部1671、枢转部1672和锁定部1673。其中,操作部1671设置在枢转部1672和锁定部1673之间并可供用户操作以开关或关闭仓盖164;枢转部1672用于将卡扣167连接至仓盖164并能使得卡扣167能绕枢转部1672转动;锁定部1673用于将仓盖164锁定至主仓室163。在一些实施例中,仓盖164设置有容纳槽1641,容纳槽1641用于容纳至少部分的枢转部1672,并可供枢转部1672在容纳槽1641中转动。枢转部1672通过一组连接组件1674固定至容纳槽1641中。在一些实施例中,连接组件1674包括一对螺钉和一个连接片,螺钉用于将连接片固定至仓盖164上,并能在枢转部1672安装至容纳槽1641时限制枢转部1672从容纳槽1641中滑出。锁定部1673为一个从卡扣167本体延伸出来的锁定勾。主仓室163还形成有可供锁定部1673贯穿的通孔1631和能与锁定勾配合的限位部1632。在一些实施例中,锁定部1673包括内侧边和外侧边。其中,内侧边紧贴限位部1632,并包括第一边1673a和第二边1673b,第一边1673a和第二边1673b倾斜相交并形成有一个夹角。第一边1673a和第二边1673b的夹角α可以为一个锐角。在一些实施例中,夹角α大于等于60°且小于等于90°。作为一种较佳的实现方式,当第一边1673a和第二边1673b的夹角α为90°时,锁定部1673的锁定效果较佳。限位部1632由通孔1631延伸出来,并形成有可供锁定部1673划过的通道和用于卡住锁定部1673的凸起。事实上,限位部1632包括第一面1632a和第二面1632b。当锁定部1673从通孔1631中穿过后,锁定部1673具有与限位部1632配合的第一位置和远离限位部1632的第二位置。当锁定部1673处于第一位置时,锁定勾与限位部1632贴合并能勾住限位部1632,此时锁定勾从限位部1632的第一面1632a滑动至第二面1632b,且锁定勾至少部分的保持在第二面1632b上,从而将仓盖164锁紧至主仓室163。当锁定部1673处于第二位置时,锁定勾与限位部1632脱离,此时锁定勾从限位部1632的第二面1632b脱离至第一面1632a,并从主仓室163的通孔1631处脱离,仓盖164能绕第一连接件165转动至任意敞开的位置。
作为一种可选的实现方式,卡扣167上还设置有弹性件1675,用于在锁定部1673处于第二位置时,提供一个弹性力,使得锁定部1673能保持在第二位置,从而使得仓盖164能锁紧至主仓室163。在一些实施例中,卡扣167上形成有一个限位凸起1676,弹性件1675一端套设在限位凸起1676上,另一端设置在仓盖164的容纳槽1641中。在一些实施例中,弹性件1675设置在卡扣167上远离锁定部1673的一端,其能与锁定部1673配合以形成一个杠杆结构,即当弹性件1675给卡扣167施加了一个向下的弹性力,卡扣167会以主仓室163上的通孔1631所在的位置为支点,使得锁定部1673对限位部1632施加一个向上的作用力,从而能将锁定部1673锁紧至限位部1632。
当用户操作操作部1671时,首先克服弹性件1675的弹性力,使得锁定部1673脱离限位部1632,并从第二面1632b滑动至第一面1632a,操作操作部1671,使得卡扣167从主仓室163的通孔1631中脱离,并使得第二连接件166跨越止点,从而使得第二连接件166能直接带动仓盖164自动转动至完全敞开状态。当需要闭合仓盖164时,用户可以操作仓盖164使得仓盖164跨越止点,从而第二连接件166能使得仓盖164自动复位至闭合位置。此时锁定部1673穿过主仓室163上的通孔1631,并从限位部1632的第一面1632a滑动至第二面1632b,在弹性件1675的作用下,仓盖164被卡扣167锁紧至主仓室163的限位部1632。
如图14所示,仓盖164包括第一盖体1642和第二盖体1643。第一盖体1642设置在靠近主仓室163的一侧,第二盖体1643设置在第一盖体1642远离主仓室163的一侧。第一盖体1642设置有网格结构1642a,一方面,设置在主仓室163中的电池包161工作时会产生一定的热量,网格结构1642a可以使得主仓室163中的热量有效的散出。另一方面,当骑乘式割草机在阳光下工作时,光辐射会增加主仓室163中的温度,此时网格结构1642a能止挡大部分的光辐射,从而能降低主仓室163中的温升。作为一种可选的实施方式,网格结构1642a可以为设置在第一盖体1642上的通孔1631。沿前后方向上,第一盖体1642具有呈“Y”形结构的主体部1642b,主体部1642b起到一定的支撑作用,其能有效的维持第一盖体1642的结构强度。网格分布在主体部1642b之外,并能连接主体部1642b和第一盖体1642的边缘部分。第二盖体1643与第一盖体1642的外形契合并能至少部分覆盖第一盖体1642。事实上,第二盖体1643为透明件,其可以由透明材料制成,其一方面能方便用户透过网格结构1642a观察主仓室163中的情况,另一方面,其与第一盖体1642的结合能够增加整个仓盖164的结构 强度。作为一种实现方式,通过设置第一盖体1642和第二盖体1643,一方面能够增强仓盖164的结构强度,使得仓盖164能够更好的保护电池包161。另一方面,通过这种双层设计,可以将仓盖164的不同功能分割至不同的盖体上,使得第一盖体1642和第二盖体1643能分别产生不同的功能。在一些实施例中,通过第一盖体1642和第二盖体1643的结合能实现不同盖体之间的不同功能的结合,并且不同盖体之间的不同功能还互相不产生影响。
图如15所示,第一盖体1642上靠近主仓室163的一侧还形成有第一加强筋1642c,第一加强筋1642c主要分布在第一盖体1642的主体部1642b。在一些实施例中,第一加强筋1642c设置在主仓室163的上方,其能有效的增强仓盖164的结构强度,从而使得设置在主仓室163中的电池包161能被仓盖164有效的保护,不至于暴露在外界而被损坏。此外,通过设置第一加强筋1642c,还能有效减小仓盖164的整体重量,使得其在强度增加的同时,更加轻便。作为一种实现方式,第二盖体1643上设置靠近主仓室163的一侧有第二加强筋1643a,第二加强筋1643a能增加第二盖体1643本身的强度,也能使得第二盖体1643更加轻便。当第二盖体1643和第一盖体1642结合时,二者的强度更高,同时也更加轻便。
如图16所示,行走组件14可以包括:第一行走轮141、第二行走轮142,在沿前后方向上,第一行走轮141设置在第二行走轮142的前侧。行走组件14还包括用于驱动第二行走轮142转动的第一驱动组件21和第二驱动组件22。这样,当第一驱动组件21和第二驱动组件22以不同的转速驱动对应的第二行走轮142转动时,这两个第二行走轮142之间产生速度差,从而使得骑乘式割草机进行转向。在一些实施例中,在一个沿第一直线101方向延伸的对称平面内,第一驱动组件21和第二驱动组件22关于对称平面对称设置。
如图16至图18所示,第一驱动组件21和第二驱动组件22分别通过连接件设置在主机架11上。由于连接至主机架11的行走组件14承载了来自主机架11上的全部重量,而设置在后侧的第二行走轮142承载了来自主机架11的大部分重量。此外,第二行走轮142是通过第一驱动组件21和第二驱动组件22连接至主机架11上的,所以,来自于主机架11上的荷载会通过第一驱动组件21和第二驱动组件22传递至第二行走轮142上。而设置在主机架11上的第一驱动组件21和第二驱动组件22作为两个独立的组件,其分别承受了来自于主机架11的荷载,从而使得第一驱动组件21和第二驱动组件22与主机架11的连 接处。作为一种实现方式,还设置了连接第一驱动组件21和第二驱动组件22的连接板组件23。当连接板组件23连接至第一驱动组件21和第二驱动组件22时,形成有一个分割至少部分主机架11的上下空间且位于主机架11的下侧的容纳空间231,第一驱动组件21和第二驱动组件22设置在容纳空间231内。这样可以有效分割主机架11的上下空间,从而避免第一驱动组件21和第二驱动组件22与主机架11的上侧空间的相关部件产生干涉。
在一些实施例中,连接板组件23包括第一连接板232和第二连接板233。其中,第一连接板232设置在第一驱动组件21和第二驱动组件22的上侧,第二连接板233设置在第一驱动组件21和第二驱动组件22的下侧。在一些实施例中,第一连接板232和第二连接板233均连接至第一驱动组件21和第二驱动组件22的齿轮箱211上。作为一种可选的实施方式,第一连接板232与第二连接板233在一个垂直于第一直线101的上下方向上平行设置。可选的,第一连接板232与第二连接板233在一个垂直于第一直线101的直线方向上还可以交错布置。从而能实现对对主机架11上下空间较大范围的分割。通过设置第一连接板232和第二连接板233,可以实现将第一驱动组件21和第二驱动组件22与主机架11连接形成一个整体,从而能显著增加第一驱动组件21与第二驱动组件22与主机架11的连接处的刚度。同时,由于此时第一驱动组件21和第二驱动组件22连接形成一个整体,其本身的刚度也增强,从而在不强化原有的第一驱动组件21和第二驱动组件22的基础上,能显著增加第一驱动组件21和第二驱动组件22的结构强度,使得第一驱动组件21和第二驱动组件22能承担更重的荷载。此外,由于设置了第一连接板232和第二连接板233,第一连接板232和第二连接板233之间形成了一个能隔离主机架11上部和下部的容纳空间231,第一驱动组件21和第二驱动组件22中的齿轮箱211至少部分被包围在第一连接板232和第二连接板233之间的空间内,避免了外界物体对齿轮箱211的伤害,有效增加了第一驱动组件21和第二驱动组件22的寿命。同时,也增加了骑乘式割草机100能适应的工作环境的复杂程度。在一些实施例中,通过设置第一连接板232和第二连接板233,还能对第一驱动组件21和第二驱动组件22起到很好的定位作用,使得第一驱动组件21和第二驱动组件22具有较好的同轴度,并能被有效的固定在一个预设位置上。
如图19所示,为了实现对第一驱动组件21和第二驱动组件22的有效控制,第一驱动组件21和第二驱动组件22内还设置有控制电路,控制电路通过连接 线212连接至外侧。在本实施方式中,连接线212设置在第一驱动组件21和第二驱动组件22的后侧伸出,并位于第一连接板232和第二连接板233之间的容纳空间231内。通过将连接线212设置在第一驱动组件21和第二驱动组件22的后侧,并位于第一连接板232和第二连接板233之间的容纳空间231内这样的设计,一方面可以使得连接线212远离动力输出组件,避免与动力输出组件产生干涉,同时也能避免在工作状态下,碎草缠绕至连接线212上,与连接线212产生干涉作用。另一方面,通过将连接线212设置在第一连接板232和第二连接板233之间,还能起到对连接线212的保护作用,避免连接线212暴露在于外界,并能充分利用第一驱动组件21和第二驱动组件22后侧的空间,使得整机的排布更加合理。最后,将连接线212设置在后侧,还能方便拆卸维修,而不用拆除前端结构。
如图20至图23所示,以第一驱动组件21为例,第一驱动组件21包括驱动电机213,变速机构214和输出轴215,其中,驱动电机213输出动力至变速机构214,变速机构214将来自于驱动电机213的动力传递至输出轴215,并驱动输出轴215转动。第二行走轮142设置在输出轴215上,并能随输出轴215同步转动。当骑乘式割草机100在工作过程中,第一驱动组件21和第二驱动组件22用于驱动骑乘式割草机100前进或后退,当通过第一驱动组件21和第二驱动组件22形成差速以实现转向或在骑乘式割草机100遭遇斜坡时,连接至输出轴215的第二行走轮142会向输出轴215传递一个较大的轴向力,该轴向力可以压迫输出轴215沿轴向运动,或者使得第二行走轮142产生脱离输出轴215的作用力。
为了避免轴向力压迫输出轴215,并使得输出轴215与齿轮箱211的连接处在轴向力的作用下磨损严重,还在输出轴215与齿轮箱211的连接处设置了第一连接组件24。第一连接组件24可以包括第一轴承241、第一垫片242、第二垫片243和保持架244,其中第一轴承241、第一垫片242、第二垫片243和保持架244沿输出轴215方向依次排布,并套设至输出轴215上。第一轴承241用于支撑输出轴215远离第二行走轮142的一端。事实上,齿轮箱211内还包括用于支撑输出轴215的第二轴承,第二轴承设置在靠近第二行走轮142的一端。第一垫片242设置在第一轴承241和第二垫片243之间,用于固定第一轴承241并可以使得第一轴承241能相对输出轴215上的传动齿轮211a具有一个预设距离。保持架244设置在第二垫片243和传动齿轮211a之间,用于提供一 个与轴向力方向相反的反作用力,从而抵消轴向力作用至传动齿轮211a和第一轴承241即第一垫片242和第二垫片243时,对传动齿轮211a、第一垫片242、第二垫片243和传动齿轮211a的磨损。保持架244可以设置为推力轴承及其他能提供轴向滑动摩擦力的零部件。作为一种可选的实施方式,保持架244为具有推力滚针244b的环形片。如图23所示,保持架244为一个围绕中心轴线分布的圆环244a结构,圆环244a的两侧围绕中心轴线分布有圆柱形滚针244b。事实上,滚针244b是嵌入至保持架244内部并至少部分暴露在圆环244a的表面之外的。可以理解的,滚针244b表面光滑且连续,能够在保持架244内自由转动,能够将保持架244与第二垫片243或者保持架244与传动齿轮211a之间的静摩擦转换为滑动摩擦。此外,由于滚针244b凸出于保持架244的圆环244a所在的平面,其能将输出轴215的轴向力作用至第二垫片243或传动齿轮211a的静摩擦转化为滑动摩擦,从而有效避免由于第二垫片243、保持架244被磨坏而进入至传动齿轮211a的间隙中,使得传动齿轮211a被卡死,造成骑乘式割草机100行走功能失效。或者,导致传动齿轮211a被磨坏,影响骑乘式割草机100的使用寿命。在一些实施例中,通过设置保持架244,能有效的化解骑乘式割草机100转向或遭遇倾斜路况时产生的沿输出轴215的轴向作用力的影响,从而有效的提高齿轮箱211的使用寿命。
如图24至图25所示,输出轴215还形成有凸起部215a,凸起部215a围绕输出轴215的周向设置,输出轴215的凸起部215a所在的圆周的直径大于输出轴215其他部分的直径。作为一种实现方式,齿轮箱211中形成用于容纳凸起部215a的容纳槽211b,凸起部215a与容纳槽211b基本契合,并被限制在容纳槽211b所在的范围内。由于输出轴215一端连接至齿轮箱211,另一端连接至第二行走轮142。当输出轴215遭遇斜坡时,由于第二行走轮142的作用,输出轴215会受到较大的轴向力,且该轴向力会使得输出轴215具有远离齿轮箱211的趋势。如果轴向力过大,会使得输出轴215在第二行走轮142的带动下脱离齿轮箱211,从而造成整个第二行走轮142脱离主机架11,从而产生较大的安全隐患。此时,由于凸起部215a的存在,其能抵消来自于第二行走轮142的绝大部分轴向力,从而有效的避免输出轴215脱离齿轮箱211。为了避免凸起部215a与齿轮箱211之间产生较大的摩擦,还在凸起部215a远离传动齿轮211a的一侧设置了套筒211c,套筒211c能有效限制输出轴215的轴向位移。在一些实施例中,在输出轴215的凸起部215a和套筒211c之间还设置有第三垫片211d, 第三垫片211d能有效避免凸起部215a与套筒211c之间在轴向力的作用下被磨损。
如图1所示,骑乘式割草机100从前侧往后侧依次设置有第一行走轮141、操作组件、动力输出组件、座椅、第二行走轮142、电源装置及集草装置25。可以理解,第一行走轮141和第二行走轮142主要用于支撑主机架11以及设置在主机架11上的其他部件,并可供骑乘式割草机100行走。第一行走轮141设置在主机架11的前端,第二行走轮142设置在主机架11的后端,操作组件、动力输出组件及座椅设置在第一行走轮141和第二行走轮142之间,通过这样的设置,可以有效保持整机的平衡,并使得各个部件的配合更加均衡,同时也能更加便于用户操作骑乘式割草机100。其中,操作组件中的第一操作元件包括两个,基本对称地设置在主机架11的两侧。在一些实施例中,第一元操作件设置在沿前后方向分布的中间位置,并可以设置在座椅的两侧。操作组件中的第二操作元件设置在主机架11的前侧并可以位于主机架11的左侧位置,从而可供用户通过一个脚即能实现对骑乘式割草机100的控制。作为一种实现方式,通过将第二操作元件设置在主机架11的前侧并位于左侧位置,还可以给主机架11的前侧预留一个较大的空间,从而可供用户的腿部自由的活动。
作为一种可选的实施方式,电源装置和集草装置25设置在主机架11的后侧。在一些实施例中,电源装置设置在靠近第二行走轮142的后侧位置,集草装置25设置在电源装置的上侧。在本实施方式中,由于电源装置中设置有多个电池包,其占据了一定体积并具有一定的质量。而设置在第一行走轮141和第二行走轮142之间的动力输出组件由于设置有刀盘、驱动电机213等部件,其也具备一定的体积和质量,其设置在主机架11的下侧。通过将电源装置设置在靠近第二行走轮142的后侧,在一个关于与主机架11的延伸平面相交的平面内,电源装置和动力输出组件关于该平面对称设置。这样可以有效的调整骑乘式割草机100的配重,使得整机在前后方向和上下方向的重量配比更加均衡,使得骑乘式割草机100更加稳定,能有效提高操作过程中的稳定性和安全性。
此外,将集草装置25设置在电源装置的上侧,并至少部分向电源装置的后侧延伸,这样可以有效的利用电源装置上侧空间和后侧空间。在不与骑乘式割草机100的其他部件产生干涉的前提下,最大限度的利用整机空间。作为一种实现方式,集草装置25通过一组连接杆连接至主机架11上,这样可以使得集草装置25充分利用电源装置上侧及后侧的立体空间,且不至于与电源装置接触 并挤压电源装置的电池仓162。同时,由于电源装置和集草装置25分别设置在不同的立体空间范围内,方便用户分别调整或维护电源装置或集草装置25。在一些优选的实施方式中,骑乘式割草机100包括集草模式和排草模式。当骑乘式割草机100处于集草模式时,集草装置25被安装至电源装置的上侧。当骑乘式割草机100处于排草模式时,集草装置25被拆卸下来。作为一种实现方式,当骑乘式割草机100处于排草模式时,在座椅和电源装置之间还可以设置有遮阳棚,遮阳棚通过连接杆连接至座椅与电源装置之间,从而使得用户在操作骑乘式割草机100时,遮阳棚具有较好的遮挡动能,同时也能较好的利用座椅与电源装置之间的夹缝空间。
如图26至图29所示,骑乘式割草机100还包括控制模块31。控制模块31设置在座椅下侧,并作为一个控制中枢,控制整个骑乘式割草机100与控制模块31构成电性连接的元器件的运行。主机架11在第一平面103内延伸,第一直线101位于第一平面103内,主机架11基本关于第一直线101对称。在一个沿左右方向延伸且与第一轴线102平行的第二直线105方向上,主机架11还基本关于第二直线105对称。第二直线105也位于第一平面103内。在一个经过第二直线105且垂直于第一平面103的第二平面104上,座椅设置在主机架11上并至少部分经过第二平面104。第一直线101与第二直线105具有一个交点106,控制模块31基本位于第一直线101与第二直线105的交点106范围内。即控制模块31基本被设置在主机架11的中间位置,这样可以最大限度的减小各个元器件连接至控制模块31的连接线的排线距离。在一些实施例中,控制模块31包括驱动控制板311、保险丝312和电源管理模块313。其中,驱动控制板311用于控制动力输出组件、行走组件14等部件。动力输出组件设置在第一行走轮141和第二行走轮142之间,并靠近前述第一直线101和第二直线105的交点106处。将用于控制动力输出组件的驱动控制板311设置在动力输出组件的上方,可以有效的减小连接驱动控制板311和动力输出组件的连接线的长度。通过这样的设置,一方面可以有效的简化线路排布,充分利用空间并减小排线的复杂性;另一方面,也能方便维修。可以理解,在一段较短的连接线上,可以快速定位故障所在位置,从而极大的缩短了检修的时间,增加用户操作骑乘式割草机100的连续性。
保险丝312连接至驱动控制板311和电源管理模块313之间,保险丝312用于保护驱动电路,防止电流过载,烧坏电路或电机等。在一些实施例中,保 险丝312至少部分位于座椅下侧,并同时位于驱动控制板311和电源管理模块313之间,从而能便于用户检修或维修。在一些实施例中,由于电源管理模块313设置在主机架11的后侧,而驱动控制板311设置在座椅的下侧并至少部分位于第一直线101与第二直线105的交点106处,从而将保险丝312设置在电源控制模块31和驱动控制板311之间能够有效的减小连接保险丝312和电源控制模块31和驱动控制板311之间的连接线的长度,方便用户检修或维修。
电源管理模块313设置在座椅后侧,并位于座椅和电源装置之间,其以靠近电源装置最近的位置设置,能充分利用座椅和电源装置之间的空间,并能有效减少电源装置和电源管理模块313之间的连接线的长度,从而使得整个控制模块31的线路排布简化,能够有效减小装配和检修的复杂度。
控制模块31还包括分线盒314,分线盒314用于连接来自各个元器件的连接线,并通过自身连接至驱动控制板311上。在一些实施例中,分线盒314设置在驱动控制板311的上侧,在方便与驱动控制板311和电源管理模块313构成电性连接的同时,还能充分利用驱动控制板311的上侧空间。通过这种立体交互式设计,在分线盒314与驱动控制板311之间不产生干涉的前提下,还能有效利用座椅下部的空间,简化装配过程,优化了排线设计,从而给用户使用、维护等带来了极大的便利。
如图30所示,主机架11沿前后方向延伸,在一个垂直于上下方向的投影平面内,主机架11沿上下方向在该投影面内的投影基本呈矩形。在一些实施例中,主机架11基本在一个平面内延伸,并呈一体式结构。通过设置主机架11在一个平面内延伸,可以有效的降低主机架11的重心,同时使得当主机架11上安装各类元器件时,整机的重心处于一个较低的位置。此外,通过设置一体式主机架11结构,可以增强主机架11的结构强度,同时减少了装配的步骤。主机架11还采用了模块化设计,从而使得主机架11能够适应不同平台的需求。
在一些实施例中,主机架11包括第一杆件113、第二杆件114和第三杆件115。其中,第一杆件113和第二杆件114平行设置,并平行于第一直线101方向。第三杆件115连接第一杆件113和第二杆件114并位于主机架11前侧。第一杆件113、第二杆件114和第三杆件115固定连接或一体成型。作为一种可选的实施方式,第三杆件115还设置有用于连接第一行走轮141的连接孔115a。连接孔115a与第三杆件115固定连接或一体成型。第三杆件115与第一杆件113和第二杆件114的连接处还设置有加强部115b。加强部115b可以是一个直角三 角形的连接块,其能增加第三杆件115与第一杆件113及第三杆件115与第二杆件114的连接面积,以增强主机架11的结构强度。可以理解,第一杆件113、第二杆件114和第三杆件115可以固定连接,也可以一体成型。第一杆件113和第二杆件114之间还设置有第三连接板116。第三连接板116设置在主机架11的前侧,第三连接板116与第二连接板233平行或相交,其能与第一连接板232和第二连接板233配合,一方面可以使得主机架11更加稳固,另一方面也能增加主机架11的结构强度,并使得主机架11能够构成一个稳固的整体。第三连接板116在一个平面内延伸,并形成可供踩踏的踩踏部116a。第一杆件113和第二杆件114的后侧还设置有防撞杆117。防撞杆117的截面呈圆形,其设置为在当电源装置安装至主机架11上时,防撞杆117围绕电源装置所在的空间且至少部分位于电源装置所在的空间之外。这样,当外物对骑乘式割草机100产生撞击,尤其是对电源装置产生撞击时,防撞杆117能有效避免外物的直接撞击,并能承担绝大部分的动能,避免电源装置在被撞击时产生损伤,造成一定的安全隐患。
主机架11是由截面为矩形管的管体围成的封闭框架结构。通过设置矩形管,使得连接至管体的各个元器件与主机架11具有较大的连接面,从而使得各类元器件与主机间的连接更加稳固。同时,也便于主机架11本身的焊接,使得主机架11具有较大的焊接面,从而保证主机架11的整体刚度。
如图31所示,在本实施方式中,骑乘式割草机100还包括驻车系统。驻车系统41包括:踏板411、踏板臂412、第一转动件413、基板414、棘轮415、第一弹性件416、第二弹性件417、第二转动件418、第三转动件419。其中,踏板411、踏板臂412、第一转动件413构成了踏板组件。在本实施方式中,踏板组件即第二操作元件。踏板臂412包括两个运行区段,当踩踏踏板411使得踏板臂412位于第一区段时,骑乘式割草机100处于非驻车状态,当踩踏踏板411使得踏板臂412位于第二区段时,骑乘式割草机100处于驻车状态。
如图以及配合驻车系统41的止转系统42。止转系统42设置在基板414的右侧。在一些实施例中,止转系统42包括触发件421、接触件422、止转开关423。其中,触发件421与第一转动件413构成同步转动。触发件421在随第一转动件413转动过程中,在转动至预设位置时,能触发接触件422,接触件422触发止转开关423,止转开关423控制第二马达停止转动,从而使得第二行走轮142的动力被切断,第二行走轮142仅受到制动作用,从而能够快速被刹住。这 里需要解释的是,止转开关423仅在触发状态下控制第二马达停止转动,当止转开关423未被触发或被触发后接触件422复位的情况下,止转开关423不控制第二马达的转动,即止转开关423仅对第二马达起暂停作用。触发件421上形成或连接有触发部421a,触发部421a设置在预设位置上。在本实施方式中,触发件421具有第一区段和第二区段,其中,触发部421a设置在第二区段上。事实上,整个第二区段均能触发接触件422,即第二区段可视为触发部421a。而触发件在第一区段转动时,并不会触发接触件422。在一些优选的实施方式中,触发部421a设置在骑乘式割草机100从非驻车状态进入至驻车状态的临界位置。事实上,触发部421a也可以设置在骑乘式割草机100进入驻车状态之前,从而便于用户刹车。
在一些实施例中,基板414上还形成有滑轨,滑轨沿左右方向贯穿基板414自身,触发件421通过紧固件与第一转动件413固定连接。触发件421在滑轨所在的范围内随第一转动件413同步转动。在一些优选的实施方式中,滑轨包括第一滑轨414a和第二滑轨414b,第一滑轨414a和第二滑轨414b位于不同的转动半径内,其均为以第一中心轴102穿过基板414所在的点为圆心的一段圆弧。第一滑轨414a比第二滑轨414b更靠近前述圆心,故第一滑轨414a的长度小于第二滑轨414b。通过设置两个滑轨,可以使得触发件421与第一转动件413的连接更加稳固。触发件421在随第一转动件413转动过程中,与第一转动件413之间不发生相对位移。
