The invention provides a normally open fork tip collision sensing device, a front fork arm and a forklift. The device comprises a chassis, a collision tongue, an elastic piece, a rotating shaft piece, a first sensor and a second sensor, the first sensor is arranged at a first position of the chassis; the collision tongue is in a U-like shape, and the first end of the collision tongue is rotationally connected with the second position of the chassis through a rotating shaft piece so as to surround the front of the first sensor; the first end of the collision tongue extends to form a limiting tongue, and the elastic piece is at least partially connected to the first end of the collision tongue; a stopping part is arranged at the third position of the chassis, so that the limiting tongue and the elastic piece are separated to form an elastic mechanism; and the second sensor is connected to a fourth position of the chassis, so that when the collision tongue rotates along with collision, the second end of the collision tongue dynamically extends into/retreats from the sensing area of the second sensor. Therefore, in a compact space, the coordinated design of the non-contact sensor and the hard collision sensing structure is realized, so that the size is reduced.

    本发明提供了一种常开型叉尖碰撞传感装置及前叉臂、叉车,其中该装置包括:底盘、撞舌、弹性件、转轴件、第一传感器、第二传感器,其中所述底盘呈类下颚状;所述第一传感器设置在底盘第一位置处;所述撞舌呈类U形状,其第一端经转轴件与底盘第二位置旋转连接,以围设在第一传感器前处;所述撞舌的第一端延伸有限位舌,所述弹性件至少部分连接在撞舌第一端处;所述底盘第三位置设有阻却部,以将限位舌与弹性件岔开形成弹性机构;所述第二传感器连接在底盘第四位置处,以当撞舌随撞击旋转时,使其第二端动态伸入/退出第二传感器的感应区。籍此以在紧凑的空间内,实现非接触式传感器与硬碰撞感应结构的协调设计,以此减小体型。
