Description

一种电子装置及电动工具Electronic device and electric tool 技术领域Technical field
本发明属于电动工具技术领域，尤其涉及一种电子装置及电动工具。The invention belongs to the technical field of electric tools, and particularly relates to an electronic device and an electric tool.
背景技术Background technique
电动工具是一种用于供操作人员的手握持进行操作，以小功率电动机或电磁铁作为动力，通过传动机构来驱动作业工作头的工具，其种类较为繁多，且具有携带方便、操作简单、功能多样、可以减轻劳动强度、提高工作效率等优点，被广泛应用于建筑、住房装潢、汽车装配、工程机械等领域，也大量进入家庭中。Power tool is a tool for the operator to hold and operate, using a low-power motor or electromagnet as power, and a driving mechanism to drive the working head through a transmission mechanism. There are many types of tools, and it is convenient to carry and easy to operate. , It has various functions, can reduce labor intensity, improve work efficiency and other advantages. It is widely used in construction, housing decoration, automobile assembly, construction machinery and other fields, and it has also entered a large number of families.
目前，电动工具通常具有调速功能，以满足不同的工况需求，其调速功能调速功能通常由一个电子装置来实现，该电子装置通常采用电子电路或微处理芯片来改变电机的级数、电压、电流或频率等方法去控制电机的转速，以使得电机能够达到较高的使用性能。At present, power tools usually have a speed regulation function to meet the needs of different working conditions. The speed regulation function is usually implemented by an electronic device, which usually uses an electronic circuit or a micro-processing chip to change the number of motor stages , Voltage, current or frequency to control the speed of the motor, so that the motor can achieve higher performance.
但是，电动工具工作环境经常容易接触到水，因此，需要将电子装置做防处理。目前常用的做法是将电子装置放置在一个胶壳内，再在胶壳内注防水胶，使电子装置密封防水，需要增加一个胶壳作为密封防水的载体。这种密封方式，需要增加一个胶壳的成本，且胶壳注胶后，无法取出，胶壳本身需要占据一定的体积，导致电子装置体积增大，进而使电动工具体积增大。However, the working environment of power tools is often easily exposed to water, therefore, the electronic devices need to be treated for prevention. The current common practice is to place the electronic device in a plastic case, and then inject waterproof glue into the plastic case to make the electronic device sealed and waterproof. An additional plastic case is needed as a carrier for sealing and waterproofing. This sealing method needs to increase the cost of a plastic shell, and the plastic shell cannot be taken out after injection. The plastic shell itself needs to occupy a certain volume, resulting in an increase in the volume of the electronic device, which in turn increases the volume of the power tool.
