Buffering assistance mechanism, door opening and closing assembly and refrigerator
The invention relates to the technical field of assistance and buffering structures, in particular to a buffering assistance mechanism, a door opening and closing assembly and a refrigerator. The buffering power-assisted mechanism comprises a fixed part, a sliding part, an elastic piece and a crank. An annular guide groove is formed in the sliding part, and a first limiting position and a second limiting position are formed in the two ends, in the first direction, of the guide groove correspondingly; the elastic piece enables the sliding part to have the tendency of sliding in the direction from the second limiting position to the first limiting position; the free end of the crank is matched with the guide groove, and when the free end moves to the two ends of the guide groove in the first direction, the free end is located at the first limiting position or the second limiting position under the acting force of the elastic piece. In the door closing process, the sliding part is pushed to move and overcome the elastic reset force of the elastic piece, thrust borne by the sliding part is absorbed by the elastic piece, and therefore collision during door closing is reduced, and door closing noise is lowered; in the door opening process, the elastic reset force accumulated by the elastic piece in the door closing process can be fully utilized to achieve assisted door opening.
本申请涉及助力及缓冲结构技术领域，尤其涉及一种缓冲助力机构、开关门组件及冰箱。缓冲助力机构包括固定部、滑动部、弹性件和曲柄。滑动部上开设有环状的引导槽，引导槽沿第一方向的两端分别形成第一限位处和第二限位处；弹性件使得滑动部具有沿自第二限位处至第一限位处的方向滑动的趋势；曲柄的自由端与引导槽配合，当自由端运动至引导槽的第一方向的两端后，自由端在弹性件的作用力下限位于第一限位处或第二限位处。关门过程中，推动滑动部运动并克服弹性件的弹性复位力，滑动部受到推力被弹性件所吸收，从而降低了关门时的碰撞，降低了关门噪音；在开门过程中可以充分借助在关门过程中弹性件所积蓄的弹性复位力，实现助力开门。
