具体实施方式
下面将结合本申请实施方式中的附图,对本申请实施方式中的技术方案进行清楚、完整地描述,显然,所描述的实施方式仅仅是本申请一部分实施方式,而不是全部的实施方式。基于本申请中的实施方式,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施方式,都属于本申请保护的范围。
需要说明的是,当元件被称为“设置于”另一个元件,它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件,它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的,并不表示是唯一的实施方式。
除非另有定义,本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的,不是旨在于限制本控制装置和电动工具系统的申请。
请参阅图1和图4,本申请的一个实施例提供一种控制装置12,用于与电池包27配合,为电动工具11提供电力。控制装置12包括第一壳体15、用于连接电池包27的电池包安装部25、设置于第一壳体15内且可以控制电池包27放电的第一控制单元120和供用户操作以控制电动工具11的第一用户操作单元121。第一壳体15包括第一壳体部分151和第二壳体部分152。电池包安装部25设置于第二壳体部分152上,可以与第二壳体部分152一体式构成,也可以通过固定的方式设置在第二壳体部分152上。电池包安装部25包括一对导轨,电池包27能够沿该一对导轨滑动从而与控制装置12接合或脱开。当然,电池包27也可通过其他方式与电池包安装部25可拆卸地连接。
第一控制单元120连接电池包27,且可控制电池包27放电,用于保护电池包27。 当第一控制单元120检测到电池包27发生异常时,例如电池包27过温、欠压或过流等,第一控制单元120可通过切断控制装置12的对外供电回路使电池包27停止放电,本实施例中,第一控制单元120的具体结构可以是一个MCU(Microcontroller Unit,微控制器)与其外围工作电路构成。
第一用户操作单元121设置于第一壳体15上,用户可通过操控第一用户操作单元121控制电动工具11工作。第一用户操作单元121包括第一开关28,第一开关28设置于第一壳体15上,位于控制装置12的对外供电回路上,用于控制电池包27向电动工具11的电力输出,本实施例中,第一开关28可以为手动按钮,供用户手动控制。
控制装置12还包括第一接口21,与第一用户操作单元121电性连接,用于通过线缆23连接电动工具11,使得第一用户操作单元121与电动工具11连接用于控制电动工具11工作。在使用电动工具11时,可以通过线缆23将控制装置12与电动工具11电性连接,则电池包27可以为电动工具11提供电能。在操作时,用户只需手持电动工具11本体即可进行操作,电池包27及控制装置12可以放置在一旁,无需承担电池包27的重量,便于用于采用电动工具11进行精细化操作。
上述提供的控制装置12,其能够适配不同种类的电动工具。这里的电动工具指的是由电力驱动的工具,包括但不限于:角磨,直磨机,热风枪,吹风机,电烙铁,吹吸机,油漆喷枪等等。可以看出,电动工具可以是带电机的电动工具,如角磨,直磨机等。也可以是不带电机的电动工具,如电烙铁等等。如此,控制装置12能够重复利用,不仅可以提升本申请实施方式所述的控制装置12的适配性,还可以降低电动工具系统的生产成本。
请参见图1和图4,列举了一种电动工具。电动工具11上设置有第二接口22,第一接口21可以通过线缆23与第二接口22连接,从而使得控制装置12与电动工具11电性连接。
电动工具11还包括第二壳体18、工作部件112和设置于第二壳体18内用于控制工作部件112工作的第二控制单元110。其中,工作部件112根据电动工具的种类不同有所不同,如一种电动工具包括电机,其工作部件112则包括电机。例如角磨,直磨机,热风枪,吹风机等。如若电动工具不带电机,其工作部件112则可以包括电阻丝、电热丝等,例如电烙铁等。
第二控制单元110与第二接口22电性连接,当第一接口21通过线缆23连接第二接口22时,电动工具11内的第二控制单元110可以与控制装置12内的第一用户操作单元121电性连接。即当第一接口21通过线缆23连接第二接口22时,用户操作第一开关28,当第一开关28闭合时第一接口21可从电池包获得电能,从而电动工具11可通过线缆23从控制装置12获取电能,电动工具11获取电能后使得工作部件112启动工作;也可以通过控制装置12内的第一控制单元120检测第一开关28的通断状态,当检测到第一开关28闭合时,第一控制单元120控制电池包27向外输出电能,从而电动工具可通过线缆从控制装置获取电能,电动工具11获取电能后,第二控制单元110控制工作部件112启动工作;此外,电动工具11内的第二控制单元110也可通过线缆检测第一开关28的通断状态,当检测到第一开关28闭合时,控制工作部件112启动工作。本实施例中,第二控制单元110可以根据内部存储的预设控制指令自动控制工作部件 112的工作参数。在这里,工作参数根据电动工具的种类不同也有所不同,如电动工具11包括电机,其工作参数则包括电机的输出扭矩、电压、转速和功率中的任一种;如若电动工具不包括电机,则工作参数包括电阻丝、电热丝的温度等。
在一个实施例中,第一用户操作单元121还包括第一调节开关35,第一调节开关35可供用户操作以控制电动工具11的工作部件112,用于产生调节电动工具11的工作参数的第一调节信号,并将该第一调节信号发送至电动工具11,或者电动工具11主动获取该第一调节信号,以使电动工具11可以根据调节信号调节电动工具11的工作参数。第一调节开关35可以为手动调节按钮,供用户手动调节。第一调节信号可以是调速信号、调温信号或者其他待调节信号。在一个实施例中,第一调节开关35用于产生调速信号。具体的,第一调节开关35为调速钮,在操作时,若用户按下第一调节开关35,第二控制单元110可通过线缆23获取用户的控制指令并根据用户的控制指令调节工作部件112的工作参数。如此,将电动工具11主体的调速功能集成至控制装置12上,也即可以采用控制装置12输出调速信号至电动工具11,进而电动工具11上可以无需集成调速功能。
在另一个实施例中,第一调节开关35用于产生调温信号。具体的,第一调节开关35为调温钮,第一调节信号为调温信号时,是将电动工具11主体的调温功能集成至控制装置12上,也即可以采用控制装置12输出调温信号至电动工具11,进而电动工具11上可以无需集成调温功能。
控制装置12不设置用于调节电动工具11的工作参数的控制部分,仅负责生成调节信号给电动工具11,控制功能仍旧由电动工具11承担,电动工具11根据调节信号进行自身工作参数的调节。具体的,第一控制单元120用于保护电池包27,如上所述,电动工具11包括工作部件112和第二控制单元110,第二控制单元110用于控制工作部件112。由于不同的电动工具及更新换代的电动工具通常会有不同的工作参数,而如果将控制功能集成在控制装置12上,势必控制装置需要存储很多的控制策略供选择,而对于更新换代的产品,旧的控制装置要么被抛弃,要么需要对配置进行升级以便于匹配新的电动工具产品,如此,会频繁需要对控制装置12进行调节甚至替换,而本申请通过将控制功能仍旧放在电动工具11上,控制装置12只负责产生调节信号给电动工具11,使得控制装置12能够更加灵活的与更新换代的新的电动工具匹配,提升了应用广度,适用性高;控制装置12的重复利用,不仅可以提升本申请实施方式的控制装置12的适配性,还可以降低整个系统的生产成本。
上述实施例提供的控制装置12通过设置第一壳体15、电池包安装部25和第一接口21,使得电动工具11无需设置用于连接电池包27的电池包安装部25,通过将电池包27与电动工具11分离设置,一方面可以减小电动工具11的体积与重量,便于携带和存储;另一方面,用户在操作电动工具11时,只需将电动工具11通过线缆23与控制装置12连接,然后将控制装置12放置在一边,便于进行精细化操作,且由于线缆23能够弯曲并具有一定长度,操作时电动工具11与控制装置12之间的距离可以发生变化,进而移动电动工具11更为方便,人机体验更佳。另外,通过在控制装置12上设置第一用户操作单元121,可以将电动工具11主体的调节功能集成至控制装置12上,也即可以采用控制装置12输出调节信号至电动工具11,进而电动工具11上可以无需集成调节 功能,降低电动工具11主体的功能集成度,从而提高电动工具11的可靠性和使用寿命。
如此,控制装置12能够重复利用,不仅可以提升本申请实施方式的控制装置12的适配性,还可以降低电动工具系统的生产成本。
本申请实施方式还提供了一种电动工具系统,其包括上述的控制装置12及与控制装置12匹配的电动工具11。电动工具11包括但不限于:角磨,直磨机,热风枪,吹风机,电烙铁,吹吸机,油漆喷枪等等。所述电动工具包括第二壳体18、工作部件112以及第二接口22;第一接口21通过电连接器30与第二接口22连接,使得控制装置12与电动工具11电性连接。第一控制单元120用于保护所述电池包27,电动工具11包括用于控制工作部件112的第二控制单元110,第二控制单元110根据内部存储的预设控制指令控制工作部件112。
在一个实施例中,电动工具11至少涵盖两种类型的电动工具。
一个实施方式中,电动工具涵盖未设置第二调节开关的电动工具及设置第二调节开关的电动工具,第二调节开关用于调节电动工具的工作参数。第二调节开关连接至第二控制单元,并用于生成第二调节信号,第一调节开关用于生成第一调节信号;第二控制单元接收第二调节信号,并根据预先设定的优先级选择第一调节信号或第二调节信号中的一个,用于调节工作部件的工作参数。
一个实施方式中,电动工具涵盖未设置第二控制单元的电动工具及设置第二控制单元的电动工具。对于设置第二控制单元的电动工具,则第二控制单元根据内部存储的预设控制指令控制工作部件;而对未设第二控制单元的电动工具,则由控制装置向电动工具传输电力即可,通过控制装置上第一用户操作单元121对电动工具工作进行控制。
一个实施方式中,电动工具涵盖未设置电机的电动工具及设置电机的电动工具,电机为有刷电机或无刷电机,第二控制单元包括电机驱动电路,工作部件的工作参数包括电机的输出扭矩、电压、转速和功率中的任一种。
当电动工具为未设置电机的电动工具时,如电烙铁,电动工具包括烙铁芯和烙铁头,其工作部件为烙铁芯,第二控制单元包括温度控制单元及加热电路。
在其中一个实施例中,控制装置12上可以设置至少两个第一接口21,每个第一接口21可分别通过线缆23连接一个电动工具11,从而控制装置12可同时为多个电动工具11供电。可以理解的是,当控制装置12上设置多个第一接口21时,多个第一接口21的具体结构形式可以不同,或者每个第一接口21的结构形式可以相同。
在其中一个实施例中,控制装置12还可以包括充电口和连接充电口的电源转换电路,电源转换电路连接电池包27或第一接口21。充电口用于连接外部电源,外部电源可通过电源转换电路为电池包27充电,或者外部电源的电力经电源转换电路转换后通过第一接口21为电动工具11供电。
在其中一个实施例中,控制装置12还可以包括至少一个第三接口,第三接口用于连接外部交流电源,并且可通过线缆连接电动工具,用于为电动工具提供交流电。上述实施例中,控制装置12可连接多个电动工具11,同时为多个电动工具11供电,且控制装置12既可为电动工具11提供直流电,也可提供交流电,供电形式多,使用方便。
下文将针对不同的电动工具分别进行说明。如图3-5所示,电动工具11以角磨为例。
如图1、图3-图5所示,电动工具11包括第二壳体18、设置于第二壳体18内的工作部件112(在本实施例中,工作部件112为电机16)、第二控制单元110以及设置于第二壳体18上的第二接口22。具体地,该第二壳体18为中空结构。该中空部分形成容置空腔。该电机16收容于该容置空腔内,进而能通过该第二壳体18对电机16进行保护,提升安全性。进一步的,电动工具11还包括驱动电路,第二控制单元110通过控制驱动电路控制电机16工作。设置于第二壳体18上的第二接口22与第二控制单元110电性连接,进而当第二接口22通过线缆23与第一接口21电性连接时,第一用户操作单元121可以通过线缆23与第二控制单元110电性连接。进而控制装置12与电动工具11电性连接。
如图4所示,线缆23具有与控制装置12连接的第一端以及与电动工具11连接的第二端。在本实施方式中,线缆23的第一端与控制装置12固定连接,其内部的导电线与第一控制单元电性连接。线缆23的第二端与电动工具11可拆卸地连接。
线缆23的第二端通过电连接器30与电动工具11连接。请参阅图图4,图6a,电连接器30包括公接头32和母接头34。其中,公接头32用于与控制装置12连接,母接头34用于与电动工具11连接。当公接头32与母接头34以电性、机械性进行连接时,电动工具11便经由电连接器30接收来自控制装置12传输的电力。
公接头共设有3个端子,分别为正极端子,负极端子以及信号端子。其中,正极端子与负极端子为电源端子,用于将安装在控制装置12上的电池包27的电力传输给电动工具11;信号端子则用于将反应用户对第一用户操作单元的具体操作的电信号传输给电动工具11。本实施方式中,公接头32被构造为插头,通过线缆23与控制装置12连接;母接头34被构造为插座。
具体的,如图6a所示,公接头32包括第三壳体,其具有第一筒部321和第二筒部322。其中,第一筒部321呈空心圆柱状,其内部固定设置有插针;第二筒部322用于容纳线缆23。
本实施方式中,插针的数目为3,分别为第一插针323,第二插针324以及第三插针325。其中,3个插针平行布置,第一插针323、第二插针324被构造为电源端子,用于将安装在控制装置12上的电池包27的电力传输给电动工具11;第三插针325被构造为信号端子,用于将反映第一用户操作单元121的操作的电信号传输给电动工具11。此处,定义第一插针323为正极端子,第二插针324为负极端子,第三插针325为信号端子。
对应的,如图7所示,线缆23内部设置3根导线232,其中,两根导线为导电线,分别与前述第一插针323、第二插针324连通;一根导线为信号线,与第三插针325连通。
如图6a、6b所示,母接头34包括第四壳体,其具有用于与第一筒部321形状适配的后部341,远离后部341的前部342以及连接后部341与前部342的肩部343。其中,后部341、前部342以及肩部343大致为圆柱形状,呈阶梯状布置;并且三者均由非导电材料制成,肩部343具有比前部342以及后部341更大的径向尺寸。后部341开设有3个用于与前述插针形状设配的插孔;并且,每个插孔内部均固定设置有用于夹持插针的夹持件344,夹持件344的另一端穿过肩部343以及前部342并伸出,形成用于连接 电动工具11的接线端子。此处,分别定义与前述第一插针323、第二插针324以及第三插针325适配的插孔为第一插孔345,第二插孔346以及第三插孔347。
请参见图6c,夹持件344沿纵长方向延伸,具有在其延伸方向的第一端3441和第二端3442。其中,第一端3441呈空心筒状结构,其外壁沿周向间隔设置有割槽3443。本实施方式中,割槽3443的数目为2,间隔180度设置。第二端3442呈半圆柱状,用于与电动工具11连接。自然状态下,即插针未插入第一端3441时,夹持件344的夹持直径最小;当插针插入后,夹持件344被撑开,夹持直径变大。
如图6a所示,将插针向垂直于其延伸方向的平面投影,第一插针323、第二插针324、以及第三插针325的轮廓近似形成一个等腰三角形;其中,第一插针323与第二插针324的间距L3为6.4mm,第一插针323与第三插针325的间距L4与第二插针324与第三插针325的间距L5相等,均为5mm。对应的,如图6b所示,将插孔向垂直于其延伸方向的平面投影,第一插孔345,第二插孔346,第三插孔347的轮廓近似形成一个等腰三角形。
本实施方式中,第一筒部321的内径为12.7mm;对应的,后部341的外径为12mm。
一种可能的实施方式中,也可选择公接头32与电动工具11连接,母接头34与控制装置12连接,只要满足二者相互配合,能够将电池包27的电力通过控制装置12传输至电动工具11即可。
本实施方式中,公接头32通过线缆23与控制装置12固定连接,母接头34与电动工具11固定连接。如此设置,当需要断开控制装置12与电动工具11的连接时,只需将公接头32与母接头34分开即可。
此时,来自电池包27的电力需经由线缆23以及电连接器30传输给电动工具11。一般情况下,线缆23中的导线所允许流经的最大电流为10A,可满足不同类型电动工具11的电力需求。但现有的电连接器中,插针的径向尺寸通常不大于1.5mm,所允许通过的最大电流不超过6A,不能满足特定电动工具的大电流需求;否则,电连接器30将发热严重,不安全。
为此,本申请的电连接器30中,用于传输电池包27电力的电源端子,也即第一、第二插针323、324的直径在1.98mm-2.02mm之间。第一、第二插针323、324所允许流过的最大电流在9A-13A之间。优选的,第一、第二插针323、324所允许流过的最大电流在10A-12A之间。
优选地,第一、第二插针323、324的直径为2mm。第三插针325用于传输信号,其流过的电流值较小,直径在1mm-1.2mm之间即可。当然,从加工便利的角度考虑,第三插针325也可具有与第一、第二插针323、324相同的直径尺寸。
进一步地,为了保证电动工具11在工作过程中,电力传输的安全性,防止公接头32与母接头34之间轻易松脱,本实施方式的公接头32与母接头34之间为过盈配合。具体的,如图6a,图6c所示,公接头32中,第一插针、第二插针323、324的直径在1.98mm-2.02mm之间;母接头中34,用于夹持第一、第二插针323、324的夹持件344的夹持直径在1.9mm-1.94mm之间。此处的夹持直径指的是夹持件344在自然状态下的夹持直径。
一种可能的实施方式中,电连接器30还设置有保持单元,用于保持公接头32与母 接头34之间的连接状态,不至于轻易松脱。
如图6a,图9所示,保持单元包括设置在母接头34上的弹性耦合部36以及设置在公接头32上的副耦合部38。其中,弹性耦合部36为金属薄片结构,整体呈波浪状,设置在后部341的外表面;副耦合部38为自第一筒部321的外表面向内凹陷的凹槽。当公接头32与母接头34相互配合,也即将第一筒部321与后部341插接,弹性耦合部36与副耦合部38相互卡接,并在副耦合部38的作用下发生弹性变形。
一种可能的实施方式中,如图9所示,副耦合部38自第一筒部321的外表面向下凹陷的距离L1为1.1mm;弹性耦合部36的波峰与波谷之间的距离L2为1.3mm;当弹性耦合部36与副耦合部38配合,弹性耦合部36的波峰弹性变形至近乎水平状态,其距波谷的距离缩小至0.7mm,也即,波峰的形变量为0.6mm;此时,波峰的一端与凹槽38的第一斜面抵接,另一端与凹槽38的第二斜面抵接。当用户需要将公接头32与母接头34断开时,其必须提供足够的拔出力以使得弹性耦合部36进一步的变形才行。
可以想到的是,副耦合部38向下凹陷的距离越深,用以将公接头32与母接头34分开的力也就越大,本实施方式中,副耦合部38向下凹陷的距离在1.05mm-1.15mm之间。
一种可能的实施方式中,也可将弹性耦合部36设置在公接头32上,副耦合部38设置在母接头34上。对此,本申请不作限制。
如前所述,为了避免公接头32与母接头34之间轻易松脱,维持二者处于连接状态的保持力不能过小;但另一方面,为了满足快速拆装,维持公接头32与母接头34处于连接状态的保持力也不可过大。故,公接头32与母接头34之间的保持力需被安排在一个合理的范围内。
本实施方式中,公接头32与母接头34之间的保持力在55N-65N之间。也即,当用户需要将电动工具11与控制装置12分开时必须提供大于55N的作用力。
当然,线缆23可通过其它方式被可拆卸地连接至电动工具11上,对此,本申请不做限定。
一种可能的实施方式中,线缆23可以独立于控制装置12设置。即,线缆23的一端与控制装置12可拆卸地连接,线缆23的另一端与电连接器30可拆卸地连接。线缆23的一端与控制装置12之间也可以设置如上所述的电连接器30。
本实施方式中,第一控制单元通过控制电动工具11的电机16的工作参数来改变电机16的工作转速。该工作参数包括但不限于电机16的电压,电机16的电流,或者电机16的电压与电流的组合。对此本申请不做规定。该第一控制单元可以是包括单片机在内的电路模块。
并且,本实施方式中,第一用户操作单元包括第一开关28和第一调节开关35。其中第一调节开关为手动调速钮35。该手动调速钮35供用户操纵,用于调节电机16的转速。
如图2所示,第一开关28设置在第一壳体15上,用于控制电池包27向电动工具11的电力传输,从而控制电机16的开启与关闭。使用电动工具11时,用户只需触发第一壳体15上的第一开关28,电力便通过控制装置12从电池包27流向电机16。
但有些电动工具,如本实施例中的角磨,需要经常性改变电机16的工作状态。如 果将用于控制电机16启停的开关28设置在控制装置12上,虽然简化了电动工具11的结构,但一定程度上也带来了操作的不便。因为在进行具体操作时,用户握持的仅仅是电动工具11本身,控制装置12通过线缆23被放置在一边;当需要改变电机16的工作状态时,用户必须前往放置控制装置12的地方对控制装置12进行操作,才能控制电机16。
为此,在其中一个实施例中,电动工具11还包括第二用户操作单元111,供用户操作以控制电动工具的工作。
第二用户操作单元111包括第二开关,设置于第二壳体18上,并与第二控制单元110电性连接,第二控制单元110可以根据第二开关的通断状态控制工作部件112(电机16)启动或关闭。当用户握持第二壳体18时,通过控制该第二开关即可控制工作部件112的开启和关闭。该第二开关可以是薄膜开关。当然该第二开关不限于为薄膜开关,还可以是其他的开关,例如光感开关,对此本申请不做规定。在操作时,用户先操作第一开关28,此时,电池包27可以向电动工具11进行电力传输,然后用户再操作第二开关,以启动工作部件112。当需要停止工作部件112时,只需操作第二开关即可。
当然,在第一壳体15以及第二壳体18上分别设置第一开关和第二开关。可能的实施方式中,也可以设置为电池包27向电动工具11的电力传输只发生在第一开关先被操作,第二开关再被操作之后。此时,电机16的停止只需操作前述任意一个开关即可。
第二用户操作单元111还包括第二调节开关,第二调节开关设置于第二壳体18上,也可以是手动调速按钮,以便用户手动操控。第二调节开关与第二控制单元110电性连接,第二控制单元110可以根据用户对第二调节开关的操作生成第二调节信号。第二控制单元110可以根据预先设定的优先级选择第一调节信号或第二调节信号中的一个调节工作部件112的工作参数。例如,当第二调节信号的优先级高于第一调节信号的优先级时,控制单元忽略第一调节信号并根据第二调节信号调节工作部件112的工作参数;当第一调节信号的优先级高于第二调节信号的优先级时,控制单元忽略第二调节信号并根据第一调节信号调节工作部件112的工作参数。当电动工具11为小型化手持式电动工具时,优选为第二调节信号的优先级高于第一调节信号的优先级,以便用户在手持电动工具11操作时对电机16的工作参数进行调节。
上述实施例提供的电动工具系统,通过将第一调节开关35设置在控制装置12上,使得控制装置12既可以适配不带调节开关的电动工具11,也可以适配带调节开关的电动工具11,可以提高控制装置12的适配性,降低电动工具系统的生产成本。通过将第二调节开关设置在电动工具11上,使得用户可以在电动工具11上调节工作部件112的工作参数,对于手持式电动工具操作更为便捷。
在一种可能的实施方式中,也可仅仅在电动工具11的第二壳体18上设置第二开关。该第二开关用于控制电机16的开启和关闭。当用户握持第二壳体18时,通过该第二开关即可控制电机16的开启和关闭。
本实施方式中,如图3所示,控制装置12还包括2个USB输出接口26,USB输出接口26设置于控制装置12的侧边。USB输出接口26输出目标电压,用于为外部电力设备,诸如手机等充电。为此,第一控制单元还包括电压转换模块,用于将电池包27的供电电压转换成目标电压。
目标电压的大小根据外部设备的需求而设定。一种可能的实施方式中,USB输出接口26可以输出目标电压值为5V,电流为1A的电力。
出于安全性的考虑,控制装置12上还可以设置一操作钮。控制装置12通过电池包安装部25连接电池包27时,用户需首先操作该操作钮,方能通过USB输出接口26为外部设备供电。
当控制装置12连接电池包27,并通过USB输出接口26为外部设备充电时,控制装置12也可以通过线缆23同时连接电动工具11,为电动工具11供电,控制其工作。当然,控制装置12也可以择一地为外部设备充电或者为电动工具11供电。
为了适配不同外部设备的接口类型,控制装置12上也可设置其他类型的输出接口,诸如TYPE-C接口,或者是USB接口与TYPE-C接口的组合,对此,本申请不做限定。
本实施方式中,如图2所示,电池包安装部25设置于第一壳体15上。具体地,电池包安装部25设置于第一壳体15的下侧,电池包安装部25与电池包27滑移配接。当电池包27连接于电池包安装部25上且控制装置12通过线缆23连接电动工具11时,该电池包27与第一控制单元和电机16形成回路;从而电池包27能够为电机16提供电力。如此控制装置12使得电池包27与电动工具11分开设置。即,控制装置12使得电池包27相对于电动工具11外置。进而相对于现有技术中的电动工具来说,本实施方式的电动工具体积更小、操作更为轻便,人机体验更佳。
本实施方式中,电池包27的电池容量为2AH。
一种可能的实施方式中,如图3所示,本申请实施方式的控制装置12还包括:用于连接在电池包安装部25上的电池包27。
一种可能的实施方式中,第一控制单元还可以包括温度检测模块和过载保护模块。具体地,该温度检测模块用于检测第一控制单元的工作温度。过载保护模块用于在第一控制单元的工作电流超过预设值时,切断电源或者切换电机16的工作模式。
无刷电机的负载能力强;并且,同等功率下,无刷电机具有比有刷电机更小的结构尺寸。为此,本实施方式的电动工具均采用无刷电机作为驱动源。该无刷电机的直径D1在17-28mm之间。进一步的,无刷电机的直径不大于25mm。
故,相较于现有技术中的由2AH电池容量的电池包供电的电动工具,本申请实施方式所提供的电动工具具有更小的电机尺寸,甚至是结构尺寸。相较于具有小结构尺寸的电动工具,本申请实施方式的电动工具能够由更大容量的电池包供电。
当然,也可以根据不同电动工具的工作特性,选择有刷电机作为驱动源。
一种可能的实施方式中,无刷电机选用外转子无刷电机。
本实施方式中的角磨,如图5所示。此类电动工具的输出轴输出旋转运动,从而驱动工作头45完成特定操作。诸如,利用角磨切削或打磨玻璃钢等工件。电机16则采用外转子无刷电机。
壳体18包括用于收容电机16以及传动机构14的第一筒部17以及第二筒部19。第二筒部19被构造为供用户抓握的手柄。其中,第一筒部17包括收容电机16的电机壳体170以及收容传动机构14的传动壳体171。并且,传动壳体171的径向尺寸小于电机壳体170的径向尺寸;第一筒部17大致沿竖直方向布置,第二筒部19大致沿水平方向布置。
由于控制单元以及电源均独立于电动工具11设置,电动工具11的结构尺寸得以小型化。本实施方式中,第二筒部19在沿水平方向的尺寸L6在80-150mm之间。也即,当用户握持第二筒部19时,用户的手几乎握住了第二筒部19的绝大部分。同时,为了保证良好的握持体验,第二筒部19的径向尺寸应设置在合理的范围内。本实施方式中,第二筒部19的直径D2在25-41mm之间,电池容量与握持尺寸的比值在2/25-2/41之间。
如图5所示,角磨在切削过程中,其真正能执行切削操作的为——工作头45超出传动壳体171外壁的那部分。换句话说,在工作头45的径向尺寸相对固定的情况下,电机轴线X1与传动壳体171外壁之间的距离L2越大,工作头45所能切削的工件厚度越小。本实施方式中,电机轴线X1与传动壳体171外壁之间的距离L7在10-18mm之间。
如图10-11所示,当电动工具11为带电机的电动工具时,电动工具11还可以为直磨机。与角磨类似,直磨机的输出轴也输出旋转运动,从而驱动工作头完成特定操作。诸如,利用直磨机进行工件的表面磨削等工作。
直磨机11的第二壳体18为一沿纵长方向延伸的筒状壳体,其提供了供用户抓握的握持部180,并且壳体18内部收容有电机16。第二壳体18与工作头相对的一端设有第二接口22,用于连接线缆23。
直磨机选用无刷电机作为驱动源,其握持部180的直径D3在23-34mm之间。壳体18在沿纵长方向的尺寸L3在120-180mm之间。
如图12-13所示,电动工具11还可以为吹风机。吹风机的工作形式为向外界输出气流。吹风机的第二壳体18上设置有出风口19,第二壳体18内还设置有电机16和风扇13。其中,风扇13由电机16驱动转动,产生气流。在第二壳体18与出风口相背对的另一端设有第二接口22,用于连接线缆23。
一种可能的实施方式中,风扇13选用离心式风扇。
在本实施方式中,吹风机不带第二用户操作单元,如需要调速,则可以由控制装置12上的第一用户操作单元控制。
如图14-15所示,电动工具11为热风枪。热风枪的工作形式是向外界输出热风。第二壳体18上设置有出风口19;第二壳体18内还设置有电机16,电阻丝17以及风扇13。风扇13由电机16驱动转动,产生气流;电阻丝17接收电池包27的电力发热,为风扇13产生的气流加热。在沿气流的流通路径上,电阻丝17比风扇13更靠近出风口19设置;如此,风扇13所产生的气流在流经出风口19的过程中,其能够被电阻丝17加热。热风枪选用有刷电机作为驱动源。
前述的直磨机、角磨等电动工具,其通过电机16驱动工作头转动完成特定作业,电池包27的电力主要用于驱动电机16转动。而在热风枪中,电池包27的电力除驱动电机16和风扇旋转,产生气流外,还需供给给电阻丝17,为其加热。需要说明的是,电池包27供给电阻丝17的电力也通过前述的为电机16供电的导电线232传输。
在本实施方式中,电动工具11内可以不设有第二控制单元和第二用户操作单元;通过控制装置12上设置的第一用户操作单元121控制电动工具11启动和关闭。控制装置12所实现的功能为向其传输电力,不涉及控制转速等功能。但如若热风枪需要调节温度和风速,在这里,工作部件则包括电机和电阻丝。
电动工具11为热风枪时,壳体18的内部还设置有温度保护模块。当气流的温度高于预设温度时,温度保护模块工作,切断传输给电机16以及电阻丝17的电力。
上述实施例中,电动工具的工作部件112为电机16,第二控制单元110可通过线缆23连接第一调节开关35或第二调节开关,并根据第一调节开关35或第二调节开关的信号调节电机的转速和电压。
在另一个实施例中,工作部件112包括电热丝,也即电动工具11为不带电机的电动工具,不带电机的电动工具11可以是电烙铁等。工作部件112的工作参数包括电热丝的温度。
如图16-17所示,电动工具11也可以为不带电机的电动工具,例如电烙铁。电烙铁11的主要用途是焊接元件及导线。为此,电烙铁11主要设置有烙铁芯41和烙铁头43。烙铁芯41包括电热丝,其中,烙铁芯41位于第二壳体18的内部,用于接收电池包27的电力发热,烙铁头43设置在壳体18的一端,用于焊接。区别于前述的动力工具,电烙铁11的壳体18内部没有电机。
当控制装置12连接电池包27且线缆23连接电烙铁11时,电池包27的电力便输出至烙铁芯41,使其加热。
本实施方式中,当连接的电动工具为电烙铁时,控制装置12所实现的功能为向其传输电力,不涉及控制转速等功能。
一种可能的实施方式中,电烙铁11的第二壳体18内部还设置有第二控制单元,用于进行温度控制。其第二壳体18上还设置有温度选择钮,供用户根据实际的需要选择温度。
一种可能的实施方式中,第一调节开关35或第二调节开关可以是温度选择钮,第一调节开关35或第二调节开关与第二控制单元110电连接后,第二控制单元110可以根据信号调节烙铁芯41的温度。
上述实施例提供的电动工具系统中,电池包既可以适配带电机的电动工具,也可以适配不带电机的电动工具,不仅可以提升控制装置12的适配性,还可以降低电动工具11的生产成本。
在其中一个实施例中,第一控制单元120可通过检测电池包27的电压、电流和温度参数中的至少一个判断电池包27的工作状态。当电池包27工作异常时,第一控制单元120切断电池包向电动工具11的电力传输,以保护电动工具11不被损坏。
在其中一个实施例中,电动工具11还包过流保护单元,用于检测流入电机或电热丝(也即工作部件)的电流值,当流入电机或电热丝的电流值之大于等于预定的电流值时,第二控制单元110控制电机或电热丝(也即工作部件)停止工作。
在其中一个实施例中,控制装置的第一用户操作单元121包括指示模块,用于指引用户完成所需操作。
在其中一个实施例中,控制装置还包括显示模块,用于显示电池包的相关信息或控制装置的相关信息,例如电池包电压、剩余电量、充电提醒等,或控制装置的型号、供电电压等。
由以上方案可以看出,本申请实施方式的电动工具系统通过设置外置的具有电池包安装部25的控制装置12,使得电动工具11内不需要设置用于为工作部件112提供电力 的电源。也即将电源与电动工具11分开设置。如此一方面减小了电动工具11的体积和重量。另一方面,在手持第二壳体18对电动工具11进行操作时,控制装置12可以放置在一边,用户不用承担其重量;并且,本申请实施方式所提供的电动工具系统10中,电动工具11同电池包安装部25分开设置,电动工具11的结构尺寸小,重量轻,更易于握持。并且电动工具系统10中的控制装置12通用于多种电动工具11中,既可以与带电机的电动工具11适配也可以与不带电机的电动工具11适配;既可以与带调速功能的电动工具11适配,也可以与不带调速功能的电动工具11适配;既可以与带控制单元的电动工具11适配,也可以与不带控制单元的电动工具11适配。如此,不仅可以提升控制装置12的适配性,还可以降低电动工具11的生产成本。叉因为本申请实施方式的电动工具系统10中的电动工具11采用无刷电机16,因此,效率更高。
一种可能的实施方式中,如图3所示,本申请还提供一种控制器,其包括前述的控制装置12以及电连接器30。其中电连接器包括设置在所述控制装置与所述电动工具其中之一上的公接头,以及设置在所述控制装置与所述电动工具其中另一上的母接头,所述公接头用于与所述母接头配合。并且,所述公接头或者母接头通过线缆与控制装置固定连接或者直接与控制装置固定连接。
本申请实施方式提供了一种电动工具系统,其包括:控制装置和电动工具;其中,控制装置包括第一壳体、第一控制单元、电池包安装部以及第一接口;第一控制单元设置于第一壳体内,用于在电动工具与控制装置连接时,控制电动工具的电机的工作参数;电池包安装部设置于第一壳体上,用于连接电池包;电池包用于为电机提供电力;电动工具包括第二壳体、设置于第二壳体内的电机以及设置于第二壳体上的第二接口;其中,第二接口与电机电性连接;当第一接口通过线缆与第二接口连接时,第一控制单元与电机电性连接。
使用时,可手持第二壳体对电动工具进行操作,而控制装置可以被放置在一边,用户不用承担其重量。
由以上方案可以看出,本申请实施方式所述的电动工具系统通过设置外置的具有第一控制单元与电池包安装部的控制装置;使得电动工具内不需要设置用于控制电机的工作参数的第一控制单元;且使得电动工具内不需要设置用于为电机提供电力的电源。也即将第一控制单元、电源与电动工具分开设置。如此一方面减小了电动工具的体积和重量。另一方面,在手持第二壳体对电动工具进行操作时,控制装置可以放置在一边,用户不用承担其重量;并且,本申请实施方式所提供的电动工具系统中,电动工具同控制单元以及电池包安装部分开设置,电动工具的结构尺寸小,重量轻,更易于握持;同时,小结构尺寸的电动工具采用电池容量为2AH的电池包供电,续航能力更强。
在一个实施方式中,该电动工具系统中的控制装置用于控制电动工具工作部件,电动工具中不设置控制单元。在该实施方式中,控制装置所实现的功能为向其传输电力,不涉及控制转速等功能。
在一个实施方式中,该电动工具系统中的控制装置用于控制电动工具的工作部件,电动工具中不设置控制单元;所述第一控制单元包括识别模块;用于识别与其连接的电动工具的类型,以选择与电动工具匹配的工作参数。在一个进一步的实施方式中,线缆的内部设置有5根导电线。对应的,插入口设置5个插入槽,连接端子设置有5个圆柱 凸起。其中,3根导电线用于将电池包的电力传输给电机,另两根导电线用于为识别功能服务。
在一个实施例方式中,第一控制单元用于控制电池及电动工具的工作部件,第一控制单元包括识别模块,识别模块用于识别与其连接的电动工具的类型,以选择与电动工具匹配的工作参数。具体的,第一控制单元具有识别功能。在控制装置通过线缆连接电动工具时,按下第一开关,第一控制单元即上电工作;第一控制单元首先识别与其连接的电动工具的类型;然后第一控制单元选择与电动工具匹配的电机工作参数,并将与该工作参数对应的电力通过线缆传输给电动工具。
具体的,可以通过电动工具端设置识别电阻。电动工具的类型不同,其所设置的设别电阻的阻值大小也会不同。当将电动工具通过线缆与控制装置电性连接后,第一控制单元获取该识别电阻的阻值大小并根据该阻值大小确定电动工具的类型,选择与其匹配的工作参数控制其工作。
第一控制单元也可以识别与其连接的电动工具的电机的类型,从而选择与电机所匹配的工作参数。
一种可能的实施方式中,可在电动工具内部设置一电路板,用于与第一控制单元进行信息传递,实现控制装置的识别功能。当控制装置通过线缆连接电动工具时,用户按下开关;第一控制单元与电路板均上电工作;第一控制单元通过前述的其中之一导电线向电路板发送识别信号;电路板在接收该识别信号后,通过其中另一导电线向第一控制单元发送能够表示其工具类型或电机类型的身份信号;第一控制单元在接收该身份信息后,判定与其连接的电动工具的类型以及电机类型,控制电动工具工作。
一种可能的实施方式中,第一控制单元可以通过无线通信的方式,诸如蓝牙技术等,识别电动工具的类型。具体的,第一控制单元设置有第一无线模块;对应的,电动工具设置有第二无线模块。当控制装置连接电池包且控制装置通过线缆连接电动工具时,按下第一开关;控制装置与电动工具共同接收来自电池包的电力,使得第一无线模块,第二无线模块分别上电工作;第二无线模块将能够表示电动工具身份信息的无线信号发出,第二无线模块接收该信号,并反馈给第一控制单元;第一控制单元根据接收到的无线信号判定与其连接的电动工具的类型,并最终选择与电动工具匹配的电机工作参数。
需要说明的是,在本申请的描述中,术语“第一”、“第二”等仅用于描述目的和区别类似的对象,两者之间并不存在先后顺序,也不能理解为指示或暗示相对重要性。此外,在本申请的描述中,除非另有说明,“多个”的含义是两个或两个以上。
以上实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
