The connecting rod type lifting device comprises a base, a connecting rod mechanism and a driving mechanism, the connecting rod mechanism comprises a lifting connecting rod, the lifting connecting rod comprises a connecting rod I, a connecting rod II and a supporting connecting rod I, the connecting rod I and the connecting rod II are hinged to two hinge seats located on the base at intervals, and the top end of the connecting rod I inclines towards one side of the connecting rod II; the top end of the connecting rod II is inclined towards one side of the connecting rod I, so that the connecting rod I and the connecting rod II form a scissor-type structure, and one end of the supporting connecting rod I is hinged to the top of the connecting rod I while the other end is hinged to the connecting rod II; the output end of the driving mechanism is used for driving the connecting rod II to rotate around the hinge seat. The lifting effect is achieved through the connecting rod mechanism, no sliding pair exists, and the lifting stability of the lifting device and the durability of a kinematic pair are improved; the connecting rod I and the connecting rod II form a scissor fork type structure, and a large lifting height is obtained under a small driving stroke; the connecting rod I, the connecting rod II and the hinge base are subjected to weight reduction design based on the topological optimization result, and the weight of the device is reduced.
本申请涉及一种连杆式升降装置,其包括:底座、连杆机构和驱动机构,连杆机构包括升降连杆,升降连杆包括连杆Ⅰ、连杆Ⅱ和支撑连杆Ⅰ,连杆Ⅰ和连杆Ⅱ分别与位于底座上间隔设置的两个铰链座铰接,且连杆Ⅰ顶端向连杆Ⅱ一侧倾斜,连杆Ⅱ顶端向连杆Ⅰ一侧倾斜,以使连杆Ⅰ和连杆Ⅱ形成剪叉式结构,支撑连杆Ⅰ一端铰接于连杆Ⅰ顶部,另一端铰接于连杆Ⅱ上;驱动机构输出端用于驱使连杆Ⅱ绕铰链座旋转。本发明中采用连杆机构实现升降效果,没有滑动副,提高了升降装置的升降稳定性及运动副的耐久性;将连杆Ⅰ和连杆Ⅱ形成剪叉式结构,在较小的驱动行程下获得较大的升降高度;连杆Ⅰ、连杆Ⅱ和铰链座基于拓扑优化结果进行了减重设计,减小了装置重量。
