The invention provides a normally-closed fork tip collision sensing device, a front fork arm and a forklift. The normally-closed fork tip collision sensing 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 an induction tail, and the elastic piece is at least partially connected to the position, close to the induction tail, of the first end of the collision tongue. The third position of the chassis is provided with a stopping part, so that the sensing tail and the elastic piece are separated to form an elastic mechanism; the second sensor is connected to a fourth position of the chassis, and the sensing surface of the second sensor faces the sensing tail. 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闭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感应尾,所述弹性件至少部分连接在撞舌第一端靠近感应尾处;所述底盘第三位置设有阻却部,以将感应尾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,其感应面朝向感应尾。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。
