The invention relates to a two-time jacking battery lifting mechanism which comprises a base, a scissor type lifting mechanism is arranged on the base, the upper portion of the scissor type lifting mechanism is fixed to the lower portion of a platform, and the two sides of the scissor type lifting mechanism are each provided with a set of crossed scissor type lifting arms. The scissor-type lifting arms in the same group are hinged together through a middle hinge shaft, the lower left ends of the scissor-type lifting arms are fixed to the base, the upper left ends of the scissor-type lifting arms are fixed to the platform, and the lower right ends of the scissor-type lifting arms are fixed to the base in a sliding mode through a first sliding assembly. The jacking device has the beneficial effects that firstly, the mode of wedge block roller auxiliary jacking and scissor fork type structure lifting is used for carrying out two-stage jacking on the platform, so that the platform can bear large force, the problem that the motor is overloaded due to the fact that the motor is excessively stressed in the initial stage is solved when jacking starting is carried out, and the working efficiency is improved; the service life of the whole two-time jacking battery lifting mechanism is prolonged, and the structural reliability of the whole two-time jacking battery lifting mechanism is improved.

    本发明涉及一种两次顶升电池升降机构,包括一个底座,所述底座上设有一个剪刀式升降机构,所述剪刀式升降机构上方固定在平台下方,所述剪刀式升降机构两侧各设有一组交叉的剪刀式升降臂,所述同组剪刀式升降臂之间通过一个中间铰接轴铰接在一起,所述剪刀式升降臂左下端固定在底座上,左上端固定在平台,右下端通过一个第一滑动组件滑动的固定在底座上,本发明的有益效果在于:1、使用楔块滚轮辅助顶升和剪叉式结构抬升的方式,对平台进行二段式顶升,使得平台可以承受较大的力并且在顶升起步的同时,不会产生初期电机受力过大导致电机过载的问题,提高了整个两次顶升电池升降机构的使用寿命和结构可靠性。
