Intelligent lock body

Abstract

The invention discloses an intelligent lock body which comprises a shell, a sub-lock, a double-spring bolt, a door bolt, a handle drive portion and a motor drive portion; the intelligent lock body comprises a limiting component which moves by taking a first column body of the shell as a rotary shaft and is movably connected with the sub-lock, a fixing piece capable of limiting the double-spring bolt, a push-pull rod which is connected with the limiting component and the fixing piece and a transmission portion which is driven and controlled by a motor drive portion and moves by taking a third column body as a rotary shaft; and the transmission portion comprises a transmission rod connected with the limiting component. When the intelligent lock body opens a door under the control of the motor drive portion, the transmission rod drives the limiting component to further drive the push-pull rod to enable the fixing piece to release limiting to the double-spring bolt. For the intelligent lock body, the motor can directly control the door bolt and the double-spring bolt; and when the motor receives a door opening instruction, all the door locked positions can be completely unlocked underthe control of the motor, so that transmission of the interior of the lock body becomes simpler when the door is opened, which is particularly convenient for a user when the user goes out of the doorfrom a room.

Description

technical field [0001] The invention relates to the field of intelligent locks, in particular to a lock body structure of an intelligent lock. Background technique [0002] At present, smart locks mostly use a bolt to control the opening and closing of the door. When the bolt extends out of the lock body, the door is closed, and when the bolt extends into the lock body, the door is opened. However, the opening and closing of the door is only controlled by the bolt to bring a lot of inconvenience to the user in the actual use process. In some cases, the door can still be kept closed when the bolt is inserted into the lock body; The safety factor of the opening and closing is also low. [0003] The applicant has applied for a Chinese patent number: 201810568644.9, and the invention name is "A smart lock body that can limit the movement of double deadbolts". This patent discloses a smart lock that can limit the movement of double deadbolts. Body, the outside of the lock body ...

AI Technical Summary

Problems solved by technology

[0004] But in actual use, especially when the door is opened from indoor to outdoor, or when there are many items to be taken when entering the door, the limit of the above-mentioned invention patent will make the transmission complicated, and all the locking parts cannot be opened directly by the motor

Especially the opening of the double deadbolt must be controlled by the sub-lock, that is, the door body must be opened by pressing the handle, which makes the actual use process inconvenient

And when the door is opened with the double deadbolt controlled by the transmission of the sub-lock, if an accident occurs in the sub-lock, the door cannot be opened, which also makes the process of opening the door more complicated.
