一种底板组件及直线电机

Abstract

本实用新型公开了一种底板组件及直线电机。底板组件包括分体设置的基板和两个侧板，两个侧板设置于基板的相对两侧；侧板与基板的连接处设有用于阻隔外部水汽进入的隔水部。本实用新型采用分体式底板设计替代传统一体式底板，分体式底板包括独立的基板和两个设置于其相对两侧的侧板，基板无需进行复杂且耗材的掏空加工，可单独采用更经济的板材或型材制造；侧板也可实现低成本的标准化生产。由此显著降低了加工难度和材料消耗，从而有效降低了制造成本。此外，针对分体结构必然存在的连接缝隙问题，在侧板与基板的连接缝隙中设置隔水部，通过隔水部阻隔外部环境中的水汽从连接缝隙进入安装腔，从而解决了分体设计所引发的防水密封性问题。

Claims
