Locking assembly, drawer assembly and storage cabinet

Abstract

The invention relates to the field of household appliances, and provides a locking assembly, a drawer assembly and a storage cabinet. The locking assembly comprises: a mounting piece; and a locking piece which is rotatably connected with the mounting piece and is suitable for being switched between a locking state and an unlocking state, wherein the locking piece is provided with a locking part and an unlocking part. In the locking state, at least part of the locking part is suitable for being located on a movement path of a to-be-locked piece, and the unlocking part is suitable for being located on an avoiding path of the to-be-locked piece; and in the unlocking state, the locking part is suitable for being located in the avoiding path, and at least part of the unlocking part is suitable for being located in the movement path. According to the locking assembly, hovering of the to-be-locked piece and automatic resetting of the locking piece can still be guaranteed under the condition of power failure without depending on a driving piece so as to facilitate next-time use, the structure is simple, the cost is low, the occupied space is small, the application range is large, and the to-be-locked piece can hover for a long time without consuming energy.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a locking assembly, a drawer assembly and a locker. Background technique [0002] In the prior art, most of the lockers are equipped with lifting drawers. Taking refrigerators as an example, the lifting drawers in refrigerators usually hover in the following ways. If the transmission system maintains a loaded state for a long time, the durability of the structure will be weakened. In addition, the above-mentioned solution using motor brakes cannot be reset after power failure; the second is to use the locking function of the stepping motor or servo motor itself However, in practical applications, it is necessary to continuously power on to maintain the locking of the stepping motor or the servo motor itself, which will cause serious heating of the motor, and the hovering state of the lifting drawer cannot be maintained for a long time, and the motor needs a large hea...

[0002] In the prior art, most of the lockers are equipped with lifting drawers. Taking refrigerators as an example, the lifting drawers in refrigerators usually hover in the following ways. If the transmission system maintains a loaded state for a long time, the durability of the structure will be weakened. In addition, the above-mentioned solution using motor brakes cannot be reset after power failure; the second is to use the locking function of the stepping motor or servo motor itself However, in practical applications, it is necessary to continuously power on to maintain the locking of the stepping motor or the servo motor itself, which will cause serious heating of the motor, and the hovering state of the lifting drawer cannot be maintained for a long time, and the motor needs a large heat dissipation space to dissipate heat
