Door opening and closing device and door opening and closing control method

Abstract

The invention discloses a door opening and closing device and a door opening and closing control method. The door opening and closing device comprises a door opening and closing control module, a drive motor, a transmission part and a fixing shaft. The door opening and closing control module generates a door opening control signal or a door closing control signal. The drive motor drives the transmission part to work on the basis of the door opening control signal and the door closing control signal. The transmission part changes the direction of first torque output by the drive motor into the second torque direction perpendicular to the first torque direction, so that the fixing shaft rotates under the effect of torque in the second torque direction to drive a door body to be opened or closed. In combination with measures such as judgment of door body opening or closing angles, obstacle judgment and obstacle time judgment, the door body is controlled to be opened or closed automatically, in the closing process, the situations that a user forgets to close the door body, or due to the fact that exerted force is not enough, the door body is not closely tightly can be eliminated, it is ensured that the door body is closed absolutely under the non-fault state, and the technical problem that in the prior art, when the force exerted on the door body is not enough, closing is not tight is solved.

Description

Technical field [0001] The invention belongs to the technical field of storage cabinet design, and specifically relates to a door opening and closing device and a door opening and closing control method. Background technique [0002] Lockers, such as self-lifting cabinets for storing refrigerated and fresh-keeping foods, mail storage boxes, etc., when many users close the door after opening the door and picking up the items, they will ignore the closing force due to holding the items in their hands or focusing on looking at the items, resulting in the door The body is not completely closed, which will affect the safety performance of the storage cabinet. For storage cabinets such as fresh-keeping cabinets, not closing the door completely will cause the leakage of air-conditioning and affect the refrigeration of other items in the cabinet. [0003] In order to avoid the problem of incomplete door closing caused by insufficient closing force of the user, in the prior art, a torsion ...

AI Technical Summary

Problems solved by technology

[0004] The application provides a door opening and closing device and a door opening and closing control method, which solve the technical problem that the door body of the existing locker is not tightly closed when the force is not enough
