Description

一种电动工具壳体及电动工具 技术领域
本发明涉及电动工具领域，尤其涉及一种电动工具壳体、设有该壳体的电动工具以及该电动工具的组装方法。
背景技术
作为常见的应用工具之一，电动工具随处可见，如电钻、电锯、切割机、角磨机等，应用范围十分广泛，包括机械工业、建筑装潢、园林绿化、木业加工、金融加工等，对社会经济发展起着不可或缺的作用。受益于锂电技术突破，电动工具逐步转为清洁能源供电，电动工具电池容量和安全性有望大幅提高，电池成本则不断降低。随着在家庭的普及率提升，电动工具需承担起多种用途，电子控制技术的突破，智能化工具逐渐走入家庭。如更多的人通过网络购买家具、智能锁然后自己进行组装，以及家庭内电器的修理、DIY制作都不可避免的会使用到电动工具，人们对电动工具的要求变得更高。传统的电动工具由于尺寸过大，重量过重，对一些人士特别是力量比较小的女士来说，使用起来特别不便，这就要求电动工具在尽量不影响性能的情况下，做到小型化、轻量化。得益于锂电池行业的发展，电池的密度在逐渐的增大，现在同样容量的锂电池可以做的很小。这时也要求电动工具壳体做的尽量小，如果像传统的电动工具一样，用螺丝对电动工具壳体进行固定，壳体内部的各组件采用加强筋固定，则电动工具的尺寸很难变得更小，同时电动工具表面的螺钉也会影响电动工具的外观和使用手感。
