The invention belongs to the technical field of electric vehicle battery replacement, and discloses a scissor type lifting device and a vehicle lifting platform. The scissors type lifting device comprises a carrying table, a pair of scissors, a base and a driver used for driving the pair of scissors to be opened or folded so as to lift the carrying table, and further comprises a first lifting mechanism, and wherein the first lifting mechanism comprises a driven wheel connected to a pivot in a coupling mode and a guide part connected to the output end of the driver; a slope surface is formed onthe guide part; and the driver can drive the guide part to move towards the driven wheel along a linear path, so that the driven wheel rolls upwards along the slope surface to open the scissors in afolded state. According to the scissor type lifting device and the vehicle lifting platform, the push/pull force needed when the pair of scissors is opened from the folded state can be reduced, and therefore the scissor type lifting device and the vehicle lifting platform are suitable for opening the pair of scissors through the small driver with relatively low output power, and the vehicle lifting platform can obtain a relatively low initial height conveniently.

    本发明属于电动汽车换电技术领域,公开了一种剪刀式抬升装置及抬车平台。该剪刀式抬升装置包括载台、剪刀、底座和用于驱动剪刀开启或收折以升降载台的驱动器,剪刀式抬升装置还包括第一抬升机构,第一抬升机构包括:从动轮,轴接于枢轴;及导引部,连接于驱动器的输出端,并形成有一坡面;驱动器能驱动导引部沿一线性路径朝向从动轮移动,使从动轮沿坡面向上滚动,以开启呈收折状态的剪刀。本发明提供的剪刀式抬升装置及抬车平台,能够降低剪刀由收折状态开启时所需的推/拉力,从而适于采用小型、较低输出功率的驱动器开启剪刀,便于抬车平台获得较低的初始高度。
