Technical Field

[0001] The utility model belongs to the technical field of service robot accessories, and particularly relates to a mechanical unlocking device for an electric control lock. Background Art

[0002] In order to prevent goods from being lost during transportation, a transport robot usually adds a cabinet door for protection. To facilitate different users, this door can usually be automatically opened, similar to the cabinet door of a honeycomb express cabinet. After the user's identity is successfully verified, the cabinet door automatically pops out, and after the goods are taken, the user closes the door manually to complete the transportation task. This requires adding an electric control lock to the cargo box of the transport robot to control the automatic opening of the cabinet door to meet the usage requirements.

[0003] However, there is a possibility that the electric control lock fails. Once the electric control lock fails, the cabinet door cannot be opened normally, which will directly affect the normal use of users. Locking important goods in the cargo box will also cause economic losses. Therefore, it is necessary to develop an electric control lock that is both beautiful and safe. Summary of the Invention
