Description

动力装置、电动工具及系统 技术领域
本发明涉及工具作业领域,尤其是一种可以为不同的电动工具的工具主体提供动力的动力装置。
本发明还涉及一种电动工具。
本发明还涉及一种电动工具系统。
背景技术
传统的电动工具包括工作部件,马达,传动机构,启动开关,控制电路,电池包等,闭合启动开关,电池包与马达之间的回路接通,控制电路控制马达开始运行,执行相应的工作。其中,当能量提供单元为电池包时,电池包可拆卸地与电动工具连接。
传统的电动工具存在的问题是,每一种电动工具均需设置马达、电池包、控制电路等模块。当一个用户购买N种不同的电动工具时,其付出的成本相当于N个马达,N个控制电路,N个电池包,N个工作部件的成本的总和。但通常情况下,用户在某一时刻仅使用一种电动工具,使得其他N-1种电动工具闲置,此种现状极大地降低了用户的投入产出比。
现有技术通过动力装置与工具主体可拆卸连接,即一个动力装置可适配不同种类的工具主体,动力装置内预先存储多种工具的运行程序,例如,动力装置适配第一工具主体、第二工具主体和第三工具主体,第一工具的功能包括a1、b1、c1,第二工具的功能包括a2、b2、c2,第三工具的功能包括a3、b3、c3,则动力装置内需要预先设置a1、b1、c1、a2、b2、c2、a3、b3、c3的运行程序,若b1、b2、b3均为调速功能,则动力装置内就存储了3个表示调速的运行程序,如此会造成动力装置内程序量大;且若需要动力装置适配第四工具主体,第四工具主体的功能包括a4、b4,由于动力装置内没有预先设置a4、b4对应的运行程序,动力装置无法识别第四工具主体的控制命令,若想要动力装置能适配第四工具主体,则需要更新动力装置内的程序,增加a4、b4对应的运行程序,才能使动力装置识别第四工具主体的控制命令。因此,现有技术扩展性和兼容性较差。相对于现有技术,急需开发一种新型的电动工具,不仅可以提高马达、电池包等通用模块的利用率,还可以提高动力装置的扩展性,减少动力装置内的程序量,无需随时更新动力装置内的程序就可以适配新的工作主体。

需要说明的是,在本发明的另一实施例中,调速旋钮内设置有电位器,电位器的不同位置对应不同电压,旋转调速旋钮,产生对应的电压信号传输给信号处理模块23,经信号处理模块23处理后传输给工具控制模块21,工具控制模块21将接收到的电压信号传输给动力控制模块11,动力控制单元根据接受的电压信号调整PWM,控制马达的转速,实现调速,当调速旋钮旋转到某一位置时,对应的速度为零,此时,该位置对应的电压信号传输给工具控制模块21,工具控制模块21将接收到的电压信号传输给动力控制模块11,动力控制模块11根据该电压信号调整PWM,控制马达停机,故本发明中的吹风机既可以通过数字信号控制马达停机,又可以通过模拟信号控制马达停机。

具体的,上述安全刹车开关S2触发,此时,刹车电路启动,马达13的三相线圈均短路,相当于接通了一个反向电路,马达13的转子由于惯性继续高速旋转,此时,马达作为一个发电机将惯性运行的电机动能转换为电能并迅速释放,产生一个反向力矩,阻止转子的惯性运行,从而实现链锯的快速刹车。在需要急停时,通过切换安全刹车开关S2的接通状态,使马达13的三相线圈同时短路,使马达13作为一个发电机将惯性的电机动能转换为电能,并迅速释放掉,提供更大的反向制动力矩,进而实现刹车急停。与机械刹车相比,解决了用户因为反踢刹车时间长,可能带来的意外人身伤害的困扰。与普通的电子刹车相比,三相线圈同时短路,能提供较大的制动力矩,缩短制动时间,经测算,刹车时间可缩短至0.1秒以内。

在本发明一实施例中,电动工具的动力装置与工具主体是可拆卸的连接,动力装置包括动力控制单元,当动力装置与上述工具主体连接时,该动力控制单元可接收上述参数设置模块所提供的预设参数,并根据该参数设置模块所提供的预设参数,控制上述工作部件进行工作。
详细地说,上述动力装置还包括驱动单元及为该马达驱动模块提供电能的电池包,当上述动力装置与上述工具主体连接时,上述动力装置的动力控制单元根据来自上述工具主体的参数设置模块的预设参数,控制上述马达驱 动模块转动。参数设置模块通过热插拔接口与动力控制单元电性连接。动力控制单元或参数设置模块为集成芯片电路。
当工具主体为多功能机的工作头时,该多功能机的工作原理是输出轴围绕自身的轴心线做摆动运动,从而带动安装在输出轴末端的附件工作头摆动运动。常见的工作头包括直锯片、圆锯片、三角形磨砂盘和铲型刮刀等。因此,当用户在输出轴上安装有不同的附件工作头后,可以实现多种不同的操作功能,如锯、切、磨、刮等,以适应不同的工作需求。在多功能机的工作头中,多功能机的刀片、连接轴等便相当于多功能机的工作部件,当动力装置与上述多功能机的工作头连接时,动力控制单元便接收来自设置在上述工具主体,也就是设置在多功能机的工作头的参数设置模块的数据参数,该动力控制单元可根据该数据参数控制上述马达驱动模块进行工作,
更详细地说,例如,当需要上述多功能机的工作头的摆动频率为25HZ,这便需要与上述多功能机的工作头所对接的动力装置的电机保持一定的转速。此时,设置在多功能机的工作头内的参数设置模块向动力装置的动力控制单元发送数据参数,动力控制单元接收来自参数设置模块的数据参数,并控制马达驱动模块的电机转速,使多功能机的工作头的摆动频率保持在25HZ。
这样,上述电动工具的工具主体是为多功能机的工作头时,动力装置可根据设置在工具主体的参数设置模块向动力控制单元所发送的数据参数,控制马达驱动模块的电机保持于一定的转速,进而可以控制工具主体的工作部件保持在一定的工作频率。
上述只是举例说明参数设置模块可向动力控制单元发送用于控制多功能机的工作头的摆动频率的实施例,但本发明不限于此,只要由参数设置模块向动力控制单元所发送的用于控制多功能机的工作头均在本发明保护范围之内。
在另一实施例中,参数设置模块也可向所述动力控制单元提供控制电机正、反转的控制参数。这里的电动工具为电钻为例,该电钻的工作原理是输出轴持续向一方向转动,从而带动安装在输出轴末端的附件工作头转动。常见的工作头包括钻头或螺丝批等。因此,当用户在输出轴上安装有不同的附件工作头后,可以实现多种不同的操作功能,以适应不同的工作需求。在电钻的工作头中,电钻的钻头、连接轴便相当于电钻的工作部件,当动力装置 与上述电钻的工作头连接时,动力控制单元便接收来自设置在上述工具主体,也就是设置在电钻的工作头的参数设置模块的数据参数,该动力控制单元可根据该数据参数控制上述马达驱动模块进行工作。
更详细地说,例如,当需要上述电钻的工作头的转速为50r/s时,这便需要与上述电钻的工作头所对接的动力装置的电机保持一定的转速。此时,设置在电钻的工作头内的参数设置模块向动力装置的动力控制单元发送数据参数,动力控制单元接收来自参数设置模块的数据参数,并控制马达驱动模块的电机转速,使电钻的工作头的转速为50r/s。
这样,上述电动工具的工具主体是为电钻的工作头时,动力装置可根据设置在工具主体的参数设置模块向动力控制单元所发送的数据参数,控制马达驱动模块的电机保持于一定的转速,进而可以控制工具主体的工作部件保持在一定的转速。
上述只是举例说明参数设置模块可向动力控制单元发送用于控制电钻的工作头的转速的实施例,但本发明不限于此,只要由参数设置模块向动力控制单元所发送的用于控制电钻的工作头均在本发明保护范围之内。
上述电动工具的动力装置可与具有不同的工作头工具主体进行对接,并根据每个不同的工作头的特性,接收来自工具主体内的数据参数,进而根据该数据参数控制与动力装置对接的工具主体的工作头工作。
本发明电动工具的动力装置可与不同的工具主体进行对接,不同种类的工具主体将用户的操作指令按照同一标准通信协议转换为控制参数传输给动力装置,动力装置再将控制参数按照上述标准通信协议转换为对应的操作指令来控制马达,且动力控制单元具有运行程序块,运行程序块中具有缺省值,动力控制单元接收工具控制单元传输的控制指令赋给缺省值,形成完整的运行程序块,控制马达运转。
本发明一个动力装置匹配多个工具主体和电池包,例如,动力装置适配第一工具主体、第二工具主体和第三工具主体,第一工具的功能包括a1、b1、c1,第二工具的功能包括a2、b2、c2,第三工具的功能包括a3、b3、c3,若b1、b2、b3均为调速功能,则动力装置内仅需要设置一个调速程序段,调速程序段中有缺省值,当第一工具主体的调速指令N1传输到动力装置内,动力控制单元将调速指令N1赋值给调速程序段中的缺省值,即调速指令N1与调速程序段结合,形成完成的调速程序控制马达以转速N1运行;当第二工具主 体的调速指令N2传输到动力装置内,调速指令N2赋值给调速程序段中的缺省值,即调速指令N2与调速程序段结合,形成完成的调速程序控制马达以转速N2运行。因此,对于多个工具主体若有相同的功能,则只需要一个程序段,大大简化了动力装置内的程序。
当动力装置需要适配新的第四工具主体时,第四工具主体将调速指令N4传输给动力装置,动力控制单元将调速指令N4赋值给调速程序段中的缺省值,即调速指令N4与调速程序段结合,形成完成的调速程序控制马达以转速N4运行,无需更新预动力装置内的程序段,这样,动力装置只需要预先设置多个功能的程序段,后期可以与不同种类的工具主体配接,而无需更新动力装置内的程序段,从而极大扩展了动力装置的兼容性。
本发明中,能够实现动力装置1在不同的电动工具主体之间进行共用的基础,是因为动力装置1为不同的电动工具所共有的部件。在共用的基础上,优选的,本发明的动力装置1采用了寿命长的马达13,如无刷电机,使得在共用的基础上能将电机的性能发挥到极致。在共用的过程中,电池包3的寿命相对无刷电机的寿命短,因此,本发明提出电池包3相对动力装置1的主壳体可拆卸。
本发明保护一种动力装置,该动力装置为与上述吹风机主体,打草机主体,链锯主体,割草机主体和修枝剪主体可拆卸连接的动力装置。当动力装置与工具主体连接时,该动力装置便可为所对接的工具主体提供电力,以使所对接的工具主体能够顺利正常的工作。
本发明还保护一种动力装置,能接收不同种类的电池包为其提供电能,动力装置与电池包可拆卸连接,电池包控制单元将电池包指令转换为对应于控制指令的控制参数并传输给动力控制单元。优选的,当动力装置适配于某一工具主体时,动力控制单元接收工具控制单元传输的控制指令,并根据所述控制指令控制马达运转。其中动力控制单元具有运行程序块,运行程序块中具有缺省值,动力控制单元接收电池包控制单元传输的控制参数赋给该缺省值,形成完整的运行程序块。其中,控制指令按照串口通讯方式由电池包控制单元传输到动力控制单元。
本发明保护一种电动工具系统,包括上述动力装置、电池包和至少一种工具主体,所述动力装置能够为上述至少一种工具主体提供动力。工具主体可以为上述吹风机主体,打草机主体,链锯主体,割草机主体和修枝剪主体, 多功能机主体、电钻主体等。动力装置和电池包与工具主体可拆卸的配接,组成完成的电动工具,该动力装置为所对接的工具主体提供电力,以使所对接的工具主体能够顺利正常的工作。
当同时产生多个操作指令且多个操作指令包括安全指令和操控指令时,优先产生安全指令,或者安全指令和操控指令并行由所述工具控制模块向所述动力控制模块传输时,动力控制单元优先响应安全指令。
优选的,操控指令预先设置优先级,工具控制单元按照优先级由高到低的顺序向动力控制单元传输操控指令。
本发明电动工具控制方法,动力控制单元和工具控制单元通过相同的通信协议对数据进行转换,可以将不同种类工具主体接收的操作指令按照标准通信协议转换控制参数,动力装置再将控制参数转换为对应的操作指令,实现动力装置在不同的工具主体之间的通用。
以上所述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。
以上所述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。
