Description

电动工具 技术领域
本申请涉及一种电动工具。
背景技术
在高海拔环境中，气压较低，许多电动工具不能可靠地工作。例如，带有空气腔的锤或锤钻在气压较低时无法维持正常的操作。一个解决办法是在电动工具内引入气压计，以便检测使用环境的气压，从而根据当地的气压改变电动工具的操作参数。
但是，增加类似气压计的传感器以及相关的零部件会增加电动工具的成本，尤其是对于大多数不在高海拔地区中的客户来说，在里面增加传感器会带来不必要的浪费和成本。另一方面，电动工具在诸如捶击等的操作过程中会产生剧烈的震动，可能会把传感器、例如气压计震碎。
发明内容
本申请通过将诸如气压计等的用于测量外部环境参数的传感器设置于电动工具的外置控制单元上解决了上述技术问题。
上述目的通过本申请的电动工具得以实现。本申请的电动工具具有至少一个工作模式，所述至少一个工作模式至少包括能够输出冲击运动的锤模式，所述电动工具包括彼此分离的外置控制单元和工具主体，所述外置控制单元包括外置通信模块和用于测量外部环境参数的实时值的外置传感器，工具主体容置有马达，与马达连接的传动机构，与外置通信模块通信连接的内置通信模块，和能够将所述电动工具置于针对所述至少一个工作模式中的当前工作模式的最佳操作参数的电路板，所述电动工具还包括能够基于所述外部环境参数的实时值确定所述最佳操作参数的处理器，所述处理器电连接于外置通信模块和外置传感器之间并且内置通信模块和电路板电连接，或者所述处理器电连接于内置通信模块和电路板之间并且外置通信模块和外置传感器电连接。
在一个实施例中，所述工具主体包括用于容置所述传动机构的传动机 构容置部和用于容置所述马达的马达容置部，所述马达容置部横向于所述传动机构容置部布置。
在一个实施例中，所述电路板被容置于所述马达容置部内。
在一个实施例中，所述处理器电连接于外置通信模块和外置传感器之间，内置通信模块经由电线与电路板电连接或者被集成于所述电路板。
在一个实施例中，所述工具主体还包括C形的主把手，所述主把手包括供使用者握持的把持部和从所述把持部伸出的分别连接到所述工具主体的传动机构容置部和马达容置部的两个连接端，所述把持部上设置有用于控制所述内置通信模块和外置通信模块之间的通信连接的通信开关。
在一个实施例中，所述外置传感器包括下述中的至少一个：用于测量外部环境压力的气压计，用于测量外部环境温度的温度计，用于测量外部环境中粉尘浓度的粉尘浓度传感器。
在一个实施例中，所述内置通信模块和外置通信模块之间的通信连接以WIFI、蓝牙或NFC的方式无线地实现，或者被以有线方式实现。

附图说明
图1是根据本申请的第一实施例的电动工具的简化示意图。
图2是根据本申请的第二实施例的电动工具的简化示意图。
具体实施方式
本申请特别针对受外部环境的变化影响较大并且在外部环境变化较大时需要改变操作参数才能正常使用的电动工具。常见的这种类型的电动工 具可以包括具有空气腔因而受外部环境的气压影响较大的锤或锤钻，受外部环境中粉尘浓度影响较大的吸尘机，受外部环境的温度变化影响较大的电动工具等，但本身去的原理不仅限于此。本申请的电动工具可以提供一个或多个工作模式。
图1和2示出了作为电动工具的示例的锤的两个实施例，其中，相同的参考标记代表相同的零部件。图示的锤可以是只输出冲击运动的锤，或者可以是输出冲击运动和/或钻削运动的锤钻。图示的锤至少可以提供输出冲击运动的锤模式，可选地还可以提供输出旋转运动的钻模式和输出冲击运动和旋转运动的锤钻模式。
参考图1，其简化示出了锤100的整体结构。锤100总体上包括工具主体10，以及与工具主体10连接的主把手20和辅助把手30。
工具主体10具有大致L形结构，包括沿着驱动轴线A1延伸的传动机构容置部40和大致横向于(例如大致垂直于)驱动轴线A1延伸的马达容置部50。沿着驱动轴线A1，传动机构容置部40包括附接有被配置用于安装或附接刀具(图中未示出，例如钻头或冲头)的工具保持架60的前端40a和相反的后端40b。图1中示意性示出了位于传动机构容置部40内的传动机构42和位于马达容置部50中的马达52，传动机构42被连接到马达52的输出轴54并被输出轴54驱动。
用于控制锤100的操作参数的电路板56也容置于工具主体10的马达容置部50内，例如电路板56布置于马达容置部50内、马达52的与输出轴54相反的一侧上。在图1的实施例中，内置通信模块58也设置于马达容置部50中，并且被配置用于与电路板56电连接。由电路板56控制的锤100的操作参数包括诸如下述的输出参数，例如锤100的冲头的冲击力和/或冲击频率或者钻头的转速。
主把手20是大致C形状的中空体。在本实施方式中，主把手20包括把持部22、以及大致横向于把持部22从其两端延伸并且用于连接到工具主体10的连接部24、26。把持部22是由使用者把持的部分，在横向于驱动轴线A1的方向、例如大致正交的方向上延伸。连接部24连接到工具主体10的传动机构容置部40的后端40b，连接部26连接到工具主体10的马达容置部50。主把手20还包括供使用者操作的开关25，开关25与电路板56通信连接以实现控制操作。用于启动电动工具的触发器28也设置有主把手 20上。
辅助把手30包括把持部32、抵接部34和带36。把持部32大致呈供使用者用单手把持的长条状部分。抵接部34是从把持部32突出的部分、例如中空状部分。例如，抵接部34具有与传动机构容置部40的外周面的一部分(例如图示的下部部分)相适配的表面。带36形成为环状。带36的一部分被接收在抵接部34内，并通过本领域内任何合适的方式(例如螺栓连接)连接到抵接部34，剩余部分从抵接部34突出并环绕传动机构容置部40的外周面的一部分(例如图示的上部部分)。
锤100还包括外置控制单元80。外置控制单元80可以包括用于测量外部环境参数的外置传感器82，和与外置传感器82通信连接的外置处理器84，其被配置为基于其测得的外部环境参数的实时值选择或确定针对锤100的当前工作模式(前述的锤模式、钻模式和锤钻模式之一)的最佳操作参数。例如，外置传感器82可以是下述中的一个或多个：用于测量环境大气压力的气压计，用于测量环境温度的温度计，和用于测量环境粉尘浓度的粉尘浓度计。可选地，外置处理器84内部可以存储有针对各操作模式的外部环境参数与最佳操作参数之间的对应映射表，其可以是一个环境参数与最佳操作参数之间的二维映射表，也可以是多个环境参数与最佳操作参数之间的多维映射表。
外置控制单元80还包括用于与内置通信模块58通信连接以将所选择或确定的最佳操作参数传送给内置通信模块58的外置通信模块86。外置通信模块86与内置通信模块58之间的通信可以通过任何已知的形式实现，例如诸如WIFI、蓝牙或NFC的无线通信连接方式，或者有线通信连接方式。外置控制单元80可以是安装有适当APP(应用程序)的手机、手环或手表，也可以配置为单独的遥控器或者网关控制器。
在图中未示出的实施例中，可选地，用来基于传感器82测得的环境参数的实时值选择或确定针对当前工作模式的最佳操作参数的外置处理器84也可以用设置于锤100内的内置处理器代替。此时，外置传感器82与外置通信模块86直接通信连接，从而外置通信模块86将外置传感器82测得的环境参数的实时值传送给内置通信模块58，内置通信模块58与内置处理器通信连接从而后者获得前者接收到的环境参数的实时值。内置处理器还与电路板56电连接，以将确定的最佳操作参数提供给电路板56，由电路板 56控制电动工具将其置于或者切换到该最佳操作参数以便能够正常工作。此时，内置通信模块58与外置通信模块86之间传输的信号是环境参数的实时值，而非图1中的最佳操作参数。优选的是，处理器84如图示设置有外置控制单元80内，这有助于减轻电动工具本身的数据处理或计算负担，简化电动工具内部电路板的设计。
在本图1的实施例中，内置通信模块58与电路板56分开设置，并且通过任何合适的形式电连接，例如通过电线路57连接到一起。
图2示出的第二实施例不同于第一实施例仅在于，内置通信模块58被集成于电路板56，无需额外固定内置通信模块58的零部件。可选地，用于替代外置处理器84的内置处理器也可以集成于电路板56。
上面参考图1和2的实施例描述了根据本申请的原理构造的锤。虽然本申请以包括三个操作模式(即锤模式、钻模式和锤钻模式)的气动锤钻为示例，但本领域内技术人员应理解，本申请的原理不仅限于此。在电动工具是如上述提供包括冲击模式在内的多个工作模式的电动工具时，本申请是特别有利的，因为冲击模式不可避免地引起电动工具本身的振动，本申请的布置有效地避免了各种反应灵敏和/或本身较脆弱的传感器受振动的影响而产生较大误差或者不能正常工作或者甚至被震碎的现象发生。
本申请的电动工具包括设置于工具主体10内的内置通信模块以及外置控制单元，外置控制单元包括用于测量环境参数的外置传感器以及用于与内置通信模块通信连接的外置通信模块，电动工具还包括内置或者外置的处理器。外置控制单元的外置传感器用于测量环境诸如气压、温度或者任何其它希望的环境参数。传感器被外置，而非设置于气锤本体上，并且经由诸如蓝牙等本领域内已知的通信方式将外置控制单元的信息传送给电动工具的工具主体，这简化了电动工具本身的结构，降低了气锤本身的成本，同时避免了在传感器安装在电动工具本身上时其工作产生的振动可能破坏(例如振坏)传感器的可能。基于测得的环境参数选择对应的最佳操作参数的处理器可以如图示实施例那样设置于外置控制单元上，此时通信模块传递的是代表该最佳操作参数的信号；处理器还可以设置于电动工具内部，此时通信模块传递的是代表对应所测得的环境参数的参数值的信号。
以上参考附图对具体示例进行了描述，本领域普通技术人员应该清楚，本申请不仅限于上述具体示例。在不脱离由以下权利要求限定的本申请的 保护范围的情况下，可以对具体配置进行多种改变，而这些改变都在本申请的保护范围内。
