四度携手进博会，蔚来ES8出任第九届进博会VIP指定用车北自科技获专利，货叉受压后向桁架机器人发出动作信号
11月6日，北自科技（603082）的发明专利《压触机构、货叉和触发方法》获授权，申请号为CN202311840464.9。
在搬运设备中，货叉下降过深可能压到托盘或板车。专利在可滑动的部件上安装感应片，并在一侧布置磁性接近开关。发生压触时，滑动位置的变化可以转化为传感器信号。机器人控制器接到信号后，判断是否需要改变驱动器动作。这样可以将托盘受压这一机械状态直接引入搬运动作的控制流程。
截至此次授权消息披露时，北自科技今年获得的各类专利授权共20项，比上年同期减少53.49%。在2026年上半年，公司研发投入为3665.94万元，同比减少5.73%。企业知识产权记录中，北自所（北京）科技发展股份有限公司名下可查到336条专利信息和197条著作权信息。
