The invention discloses a lifting device, a drawer and a freezer, and the lifting device comprises a lifting assembly which is used for bearing a lifted object and comprises at least one driving connecting rod; the transmission assembly comprises at least one driving transmission structure and a worm transmission structure; one end of each driving connecting rod is hinged to the lifted object, the other end of each driving connecting rod is hinged to the driving transmission structure, and the driving transmission structure is further connected with the worm transmission structure; and the driving transmission structure and the worm transmission structure are matched with each other and jointly drive the driving connecting rod and the lifted object to do lifting motion along a parabolic path. Therefore, when the lifted object descends along the parabolic path, the descending speed can be slowed down, the impact force generated in the descending process is reduced, and the service life of the lifting device is prolonged.
本发明公开了一种抬升装置、抽屉及冷柜,包括:抬升组件,用于承载被抬升对象,所述抬升组件包括至少一个主动连杆;传动组件,包括至少一个主动传动结构和蜗杆传动结构;每个所述主动连杆的一端均与所述被抬升对象铰接,每个所述主动连杆的另一端分别与所述主动传动结构铰接,所述主动传动结构还与所述蜗杆传动结构连接;其中,所述主动传动结构和所述蜗杆传动结构相配合,共同带动所述主动连杆及所述被抬升对象沿抛物线轨迹做升降运动。这样当被抬升对象沿抛物线轨迹做下降运动时能减缓下降速度,减小下降过程产生的冲击力,延长抬升装置的使用寿命。
