电动工具
本申请要求在2020年06月16日提交中国专利局、申请号为202010546113.7的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及电动工具技术领域，例如，涉及一种电动工具。
背景技术
曲线锯在生产加工过程中有着较为广泛的运用，曲线锯主要用于切割金属和木材，其中曲线锯常配备有工作附件，锯片作为曲线锯的工作锯片，在工作时，锯片被安装于输出头上，且伸出底板朝向工件安装，由此将底板抵接于工件表面并通过锯片的往复运动实现切割。曲线锯的锯齿被磨尖，具有切割锋利等特点，因此在不使用时通常应将锯片从主机上拆下，避免因锯片外露而对用户造成安全隐患。
但在使用的短暂间隙，频繁拆卸锯片费时费力，同时由于锯片外露于底板设置，无法将曲线锯通过底板站立于工作台上，因此在使用的间隙用户通常会将曲线锯横卧于工作台上，此时的锯片仍然具有误伤用户的风险。
另一方面，现有的曲线锯机身通常设置为拱形，机身一体设置，中间挖设有允许用户手穿过进行握持的开口，机身顶部设置有横卧的握持部，底部与底板连接，使用时用户握持于机身的顶部，其中上述机身结构臃肿，顶部的握持部距离底板和输出件的距离较远，操作不灵活。而且臃肿的机身结构导致曲线锯无法在一些狭小的空间进行操作，例如贴近墙面或壁面处或者两个壁面的夹角处。
其次，现有的曲线锯为了便于用户清楚的查看切割情况，通常在输出件的端部设有照明单元，用于对锯片的切割进行照明，但现有的照明单元通常是与输出单元同轴设置的，导致切割时始终存在某些角度无法被照射到；另外，现有的照明单元的尺寸设置不合理，有些照明单元尺寸较小，虽然有利于清晰的照射，但光线的覆盖范围较小，有些照明单元尺寸较大，虽然确保了照射光线能够覆盖一定的范围，但由于工作附件周边的光线分散无法进行清晰地照射。

其中本实施方式中第一机身111沿大致垂直于底板组件300的上下方向延伸，第二机身112沿大致平行于底板组件300的前后方向延伸，其中本申请中的上下方向指平行于第一轴线102的方向，远离底板组件300的一侧为上方， 靠近底板组件300的一侧为下方，前后方向指平行于第二机身轴线103的方向，靠近工作附件的一侧为前方，靠近电池包的一侧为后方。
如图5所示，底板组件300设置于机身110外，并与第一机身111连接，底板组件300包括底板310和转动连接部320，其中底板310与工件接触，转动连接部320与第一机身111转动连接，其中转动连接部320与第一机身111构成为以第一轴线101为轴的转动连接，其中第一轴线101平行于底板310所在平面，从而可实现曲线锯100的斜切割。
参见附图5，底板130形成有用于与工件接触的底板平面，转动连接部320用于使底板130与机身110构成连接，转动连接部320具有自底板130朝向机身110的凸起，转动连接部320大致为拱形，转动连接部320基本沿平行于第一轴线101的方向延伸；转动连接部320通过连接组件与机身110连接。
参见图3-图4，动力组件140包括电机141以及传动组件，电机141经传动组件连接至输出件120，其中本实施方式中传动组件包括偏心齿轮组件142；本申请的输出件120为往复杆121，往复杆121沿平行于第一机身111的轴线方向延伸，往复杆121由电机141驱动往复运动。
具体地，如图4所示，电机141设置于第二机身112中，电机输出端的电机齿轮与偏心齿轮啮合，电机141旋转带动偏心齿轮旋转，从而带动换向杆的上下往复运动。
其中夹持装置130与往复杆121连接，夹持装置130用于夹持工作附件400，本申请实施方式中的工作附件400为锯刀；锯刀设置在机身110外，锯刀的一侧形成有锯齿，通过锯刀的往复运动以切割工件。夹持装置130设于往复杆121的端部，工作附件400的部分插入并固定至夹持装置130。具体地，夹持装置130内形成有腔室，当操作附件400安装至夹持装置130时，操作附件400的一部分被容纳固定在腔室内。

通过设置沿平行于底板310延伸的平衡加强部152，可提高轴承架150与底座组件300的连接强度，同时也提高了该机身整体的强度；另一方面，通过将平衡加强部152沿远离第一机身111的方向延伸，可提高整机的平衡性，避免因第一机身111的较重自重而引起的机身不平衡，从而避免用户使用时需对第二机身112施加较大的作用力以平衡整机，提升了用户的操作体验。
如图5所示，平衡加强部152伸出机第一机身111设置，且平衡加强部152伸出机身后与底板组件300的转动连接部320连接，由于转动连接部320具有一个突出的外圆周面，因此平衡加强部152的底部设置有与外圆周面配合的凹陷的内圆周面，外圆周面与内圆周面同轴设置，转动连接部320通过连接组件与平衡加强部152连接。
具体地，参见附图5，转动连接部320包括靠近底板310的内部区域以及远离底板310的外部区域，其中转动连接部320的顶部中心设有连接孔321，连接组件包括方螺母331、夹紧压板332和螺钉333，其中夹紧压板332与连接孔321对应地设置于内部区域中，方螺母331与连接孔321对应地设置于外部区域中，螺钉333依次穿过夹紧压板332、连接孔321后与方螺母331固定连接。

当然，为了进一步提高轴承架与机身的连接强度，所述加固组件1501还包括设于所述支承部上的连接凸台156，连接凸台156内设有螺钉连接孔。与之对应的，在机身内壁处也设有螺钉孔，采用螺钉可将连接凸台156与机身固定，由此进一步提高了轴承架与机身的连接强度，使得连接更可靠稳定。
其中本实施方式中的轴承架150为一体式结构，其可以为铝轴承架，当然 也可以设置为其他金属轴承架，在此不作限制。
电池包200与第二机身112的后端连接并对动力组件供电，具体地，电池包200与第二机身112的展脚处连接，在第二机身112的展脚处还设置有控制组件，控制组件主要包括控制电路板。
其中参见附图6，电池包200包括第一支撑单元210，底板组件300包括第二支撑单元340，其中第一支撑单元210和第二支撑单元340位于同一支撑平面700内；第一支撑单元210和第二支撑单元340共同支撑曲线锯100使其站立，使得工具站立时，工作附件400朝向支撑平面700。
通过在工具上设置第一支撑单元和第二支撑单元，使得工具在使用的间隙可站立于工作台面，避免因工具无法站立，而将工具横卧于台面时导致的工作附件外漏，或者因工具的滑动或者掉落而带来的安全隐患。
其中第一支撑单元210被设置为线支撑单元或面支撑单元，第二支撑单元340也可被设置为线支撑单元或面支撑单元。本实施方式中电池包200上的局部外壳构成为第一支撑单元210，其中电池包200外壳与工作台面接触部分可以是的面接触或者线接触，例如可以是电池包200的整个底面作为第一支撑单元210，其中底面指电池包上与插接端相背的一面；本实施方式中底板310上背离输出件的后侧边构成所述第二支撑单元340，其中后侧边指位于底板310后方的一侧边。
通过将底板310的后侧板和电池包200的部分外壳共同支撑工具，一方面使得工具可以在使用间隙可以站立，避免直接将工具横卧于操作台面上，而带来安全隐患；另一方面在确保工具站立的基础上，使得工作附件朝向支撑平面700，也避免了在使用间隙中为确保安全反复地拆装工作附件。
其中本实施方式中的第一支撑单元210与第二支撑单元340间隔设置，且当工具站立时，工具的重心向支撑平面700的投影位于第一支撑单元210与第二支撑单元340之间。通过上述设置使得工具的站立更稳定，避免因站立不稳而产生的工具倾倒。其中，当工具站立时，底板310的表面与支撑平面700的夹角为α，则35°≤α≤60°，可选为45°≤α≤50°。
上述角度设置，在确保工具站立的基础上，进一步确保了站立时工具上的工作附件会尽可能的接近操作台面，由此进一步提高了工具站立时的安全性，避免了工具站立时工作附件误伤操作者。
本实施方式中的曲线锯100包括两个握持部，其中包括位于第一机身111上的第一握持部1110，以及位于第二机身112上的第二握持部1120。当用户操作曲线锯100时，既可以握持于第一握持部1110，也可以握持于第二握持部1120， 或者可以双手分别握持于第一握持部1110和第二握持部1120，其中本实施方式中，第一机身111的前端构成第一握持部1110，用户可将手掌握持于第一机身111的前端，拇指环绕至第一机身111的顶部后侧，第二机身112的外周壁构成为第二握持部1120。
其中如图2所示，在第一握持部1110还包括第一弹性部1111，同样地在第二握持部1120也包括第二弹性部1121，其中第二弹性部1121几乎完全覆盖第二机身112的外周壁。
第一弹性部1111至少覆盖第一机身111的前壁，其中第一弹性部1111覆盖于第一机身111外壳的面积比例大于等于50％，及第一机身111外壳上超过50％的区域覆盖有第一弹性部。
本实施方式中第一弹性部1111覆盖第一机身111的前壁，并从前壁延伸至侧壁和顶壁，覆盖部分侧壁和顶壁。通过设置有第一弹性部1111可以提高用户的使用手感，减缓在切割过程中因震动而引起的操作疲劳。
参见附图7，本申请的第一机身111包括位于其后侧壁上的上指挡部160和下指挡部170，其中上指挡部160被设置为位于第二机身112的上方；下指挡部170被设置为位于第二机身112的下方；其中上指挡部160和下指挡部170之间的前后距离的差值△L，则-15mm≤△L≤30mm，其中△L小于0指下指挡部170位于上指挡部160的后方，△L大于0指上指挡部160位于下指挡部170的前方。同时若第二机身112的外径为D,则35mm≤D≤65mm。本实施方式中包括两种握持位置的设置，其中第一种握持位置为上指挡部160位于下指挡部170的前方，此时将上指挡部160与下指挡部170的前后距离差△L为3mm＜△L≤15mm。
相关技术中为了使得整机结构紧凑，通常在握持机身的部位无法允许三指环绕握持，通常是用户的拇指和食指环绕于握持部，其余手指贴于机身侧壁，因此抓握机器时，只能依靠拇指和食指之间虎口的夹持力握持，此类握持费力且不可靠，用户长时间操作极容易不舒适。
本申请实施方式通过设置上指挡部160与下指挡部170的前后距离关系在上述范围内，可实现用户的至少三指握持，即至少允许三指环绕于第二机身的下方，此时第二机身112下方的手指贴近于下指挡部170，用户手部虎口贴近于上指挡部160，此种握持方式可靠且舒适度较高，便于用户轻松拿放机器。
当然作为可替换的实施方式，也可设置下指挡部170与上指挡部160的前后距离差△L为-10mm≤△L≤3mm。
将上指挡部160和下指挡部170的前后距离设置在上述范围内，可实现用户的至少四指握持，即至少允许四指环绕握持于第二机身的下方，此种握持方 式也具有利于提高用户的握持舒适度和握持可靠性。
本申请实施方式中通过将上述第二机身112设置在上述尺寸范围内，有利于用户单手握持，且提高了用户手部握持面积占第二机身外周面的比例，提高了握持的可靠性；同时配合前后指挡的相对位置设置，使得用户的握持更加舒适，有利于提升用户的使用体验；且允许用户三指甚至四指握持，由此以提升用户的握持舒适度，也提高了用户对机器的操控性。
如图5所示，本实施方式中底板310包括沿前后方向延伸的一对第一边311以及沿左右方向延伸的一对第二边312，其中第一边垂直于第二边312，第一边311相交于第二边312较短，其中参见附图8，第二机身112向底板130的投影包括左极限外缘1123和右极限外缘1122，其中左极限外缘1123和右极限外缘1122均位于一对第一边311之间；其中左极限外缘1123与与其相邻的第一边311间隔设置，且右极限外缘1122与与其相邻的另一第一边311’间隔设置。
左极限外缘1123与与其相邻的第一边311的左右方向的间距H1大于等于5mm，且小于等于15mm；同样地右极限外缘与与其相邻的另一第一边的左右方向的间距H2大于等于5mm，且小于等于15mm。
其中，本实施方式中的左极限外缘指第二机身112外壳的最左端边缘，即距离左侧第一边311最近的轮廓线或者点；右极限外缘指第二机身112外壳的最右端边缘，即距离右侧的第一边311最近的轮廓线或者点。
参见附图8，图中上方为右极限外缘1122，下方边缘为左极限外缘1123，其中通过将第二机身的左右极限外缘设置于底板的一对第一边内，使得第二机身112在竖直使用过程中与底板的第一边边缘存在间隙，从而有利于工具在狭小空间操作，例如当底板第一边311紧贴墙壁或者物体外壁操作时，第二机身112的外壁与墙壁或物体外壁之间存在间隙，因此有允许用户手握持的空间。
参见附图8-图10，其中本申请实施方式中的曲线锯100还包括设于输出端180的照明单元800；照明单元800通过导线与控制机构连接。其中照明单元800环绕或者部分环绕输出件120设置，其中本实施方式中的照明单元800为圆环形照明单元，照明单元800与输出件偏心设置。当然其也可以为不封闭的环形，或者是马蹄形照明单元，在此不作限制。
其中参见附图10，圆环形照明单元800的中心轴线与输出件120的中心轴线的距离a大于0且小于等于5mm。
具体地，参见附图8和图10，本申请实施例中的夹持装置130大致为圆柱形，其中的照明单元800的外径大于夹持装置130的外径，且照明单元800的外径d1与夹持装置130的外径d2之比大于1且小于3，即1＜d1/d2＜3。
将照明单元800与夹持装置130偏心设置，有利于照明单元800更加清晰的照射于工作附件的切割位置，从而避免了工作附件切割位置位于照明单元800的盲区，使得照射更加清晰。同时将照明单元800的外径与夹持装置130的外径限定在如上范围内，避免了照射单元800因尺寸过小而导致的照射范围过小，又避免了照射单元800因尺寸过大而导致的光线强度不够，因此上述设置既确保了照明单元800能够照射覆盖工作附件周边一定范围，也确保了其能够对工作附件进行清晰照射。
本申请的曲线锯100还包括开关组件，其中本实施方式中的开关组件500包括推动键510、拉杆520和开关530，其中开关530设置于第二机身112中，推动键510与拉杆520连接，推动键510设置于第二机身112外，拉杆520设置于第二机身112内并沿第二机身112的轴线方向延伸，通过拨动推动键510可带动拉杆520沿第二机身112的轴线方向移动。
如图11-图11所示，推动键510设于拉杆520上，拉杆520包括触发部523、细颈部521和连接部522，其中触发部523用于触发开关530，连接部522连接细颈部521和推动键510。
具体地，如图11所示，第二机身112内的后轴承座145内设置有贯穿的开口1451，细颈部521穿过开口1451并在开口1451中滑动移动。触发部523上设置有连接孔5231，连接孔5231与开关530的触发单元连接，其中开关530的触发单元具体为一种拨钮531，连接孔5231套设于拨钮531上，通过推动键510带动拉杆520往复运动从而带动拨钮531打开或者关闭。其中开关530通过导线与控制组件电连接，开关530可通过控制组件控制电机141的启停。
其中在连接部522上还设有引导推杆520与第二机身112的内壁滑动连接的导向件，具体地，导向件包括设于所述连接部522上的滑槽，以及设于所述第二机身112内壁的导向筋。当然，也可在连接部522上设置有导向筋，在第二机身112内壁挖设有导向凹槽，对此不作限制。
通常根据握持习惯，用户握持时手指通常靠机身前端，因此将推动键设置于前端更有利于用户操作，本实施方式中通过设置包括细颈部的开关拉杆，使得细颈部穿过电机后轴承座145设置，在此基础上，既实现了推动键510在第二机身上靠前设置，同时又满足了拉杆520与位于第二机身后侧的开关530的电连接；另外，也无需在第二机身内预留用于布置拉杆的额外空间，缩小了第二机身的尺寸，尤其是第二机身的外部径向尺寸。
参见附图13，本申请的曲线锯100还包括调速组件600，其中调速组件600包括调速旋钮610、调速电路板和调速导线，其中调速组件600通过导线与电池包200电连接，调速电路板通过导线与控制机构的电路板连接，用于实现对电 机141的调速控制。调速旋钮610设置于所述第一机身111的顶部，且调速旋钮610具有可围绕其旋转的旋转轴线611，其中旋转轴线611与底板310垂直设置，或者旋转轴线611与底板310平行设置。其中将调速旋钮610设置于第一机身111的顶部，使得用户在握持的同时可便捷地进行调速操作。
其中如图13所示，本申请实施方式中，调速旋钮610的旋转轴线611与底板垂直设置，且旋转轴线611与第一机身轴线102的距离L大于等于10mm且小于等于25mm。
具体地，参见附图14，调速旋钮610设置于第一机身111后侧的安装区域900，具体地，指调速旋钮610的旋钮中心612位于安装区域900中。其中安装区域900包括第一安装区域910和第二安装区域920，其中第一安装区域910指第二机身轴线103围绕第一机身轴线102顺时针大致旋转90°所扫过的区域，第二安装区域920指第二机身轴线103围绕第一机身轴线102逆时针大致旋转90°所扫过的区域。通过将调速旋钮610按照上述方式设置，更有利于用户的调速操作，提升用户的使用体验。
