基于仿真分析的冰箱门体自锁件的优化设计

Optimization design of door self-locking of refrigerator based on simulation analysis

冰箱门体自锁件使得冰箱门体关闭后具有一定的预紧力,使门体上的门封与箱体能够紧密压合。合理的自锁件设计,可以在保证预紧力的前提下使得用户在关门过程中力感更加平缓顺畅;不合理的设计,则会导致开关门力感体验差、门体不能很好地闭合等问题。针对某冰箱门体自锁件在关门过程中推门力过大的问题,借助仿真软件对关门过程中该自锁件进行仿真分析,改进自锁件的助吸器结构,形成最终设计方案。结果表明:最终改进的自锁件在保证预紧力的前提下可以大幅降低关门过程中的推门力,同时自闭阶段的自锁力大小适中,满足用户需求,为设计及优化自锁结构提供参考。

The door self-locking of refrigerator makes the door body have a certain pre-tightening force after it is closed,it makes the door seals on the door body and the box body can be tightly pressed.The reasonable design can make the user close the door more gently and smoothly under the premise of ensuring the preload;the unreasonable design will lead to a poor experience of opening and closing the door,the door body cannot be closed well and so on.In view of the problem that the door self-locking of a certain refrigerator has excessive pushing force during the door closing process,analyzes the self-locking part in the process of closing the door with the help of simulation software,improves the structure of suction assisting device,and the final design scheme was formed.The results show that the final improved self-locking part can greatly reduce the pushing force during the door closing process under the premise of ensuring the preload,the self-locking force in the self-closing stage is moderate at the same time,satisfies the needs of users,this provides a reference for designing and optimizing self-locking structure.
