Referring to fig. 1 to 3, the power-off elastic reset mechanism for a sliding door provided by the utility model comprises: the door comprises a support 1 and a door wing 2 connected to the support 1, wherein a driving assembly and a rocker 3 driven by a swing arm are mounted on the support 1, and the rocker 3 is connected between the driving assembly and the door wing 2;

and the elastic component is connected at the joint of the rocker 3 and the driving component.

The smooth door power-off elastic reset mechanism is mainly applied to emergency opening of a translation gate in a power-off state, and is specifically carried out through an elastic component connected at the joint of a rocker 3 and a driving component. The rocker 3 mainly transmits, the power output of the driving component is converted into the sliding of the door wing 2, and the rocker 3 is specifically converted into the translation and the stretching of the door wing 2 on the support 1 through the transmission of the swing arm in the operation process, so that the rocker 3 drives the door wing 2 to open and close on the gate.

In the operation process, the rocker 3 receives the driving force from the driving assembly, and can overcome the deformation elasticity of the spring assembly to normally drive the door wing 2 to extend outwards. Once the power failure condition occurs, the door wing 2 in the extending state can elastically reset under the action of release elasticity accumulated by the spring assembly in the compression state, so that the rocker 3 retracts towards the side swing arm of the bracket 1, and then the rocker drives the door wing 2 to retract to the gate case body to realize the elastic reset of the smooth door in the power failure condition.

When the power-off condition occurs, the spring force accumulated by the coil spring 6 is released because the coil spring is no longer subjected to the output external force of the driving assembly, the coil spring 6 can be forced to deform to the release state, and the rocker 3 drives the door wing 2 to reset and retract to the opening state of the translation gate, wherein the door wing 2 swings towards the retracting direction of the door wing 2 under the action of the spring force released by the coil spring 6.
