Full-automatic indoor door lock

Abstract

The invention relates to a full-automatic indoor door lock. The full-automatic indoor door lock comprises a lock cylinder and a control box, the lock cylinder comprises a lock cylinder shell, a lock cylinder shifting wheel and a lock cylinder rotating shaft, one end of the lock cylinder shell is connected with the control box, the lock cylinder rotating shaft is arranged on the side, close to the control box, in the lock cylinder shell, and a driving motor, a bevel gear transmission mechanism and an unlocking rotating shaft are arranged in the control box; and the bevel gear transmission mechanism comprises a first large bevel gear, a second large bevel gear, a driving small bevel gear and at least one driven small bevel gear, the first large bevel gear and the second large bevel gear are oppositely arranged in a spaced mode, and the driving small bevel gear and the driven small bevel gear are evenly distributed in the circumferential direction and meshed with the first large bevel gear and the second large bevel gear. The driving motor is connected with the driving small bevel gear, the unlocking rotating shaft axially penetrates through the first large bevel gear and the second large bevel gear and is in transmission fit with the first large bevel gear, and the lock cylinder rotating shaft is in transmission connection with the unlocking rotating shaft. The full-automatic indoor door lock has the advantages of simple structure, small volume, low cost, high reliability, long service life and the like.

Description

technical field [0001] The invention relates to a lockset, in particular to a fully automatic indoor door lock. Background technique [0002] With the continuous development of the "Internet of Things", fully automatic indoor door locks have gradually entered people's field of vision, bringing great convenience and protection to people's lives and safety. Fully automatic indoor door locks are different from traditional mechanical locks. More intelligent door locks in terms of user identification, security, and management, covering specific types of lock products such as fingerprint locks, electronic combination locks, electronic induction locks, networked locks, and remote control locks. [0003] In modern life, automatic indoor door locks are more and more widely used because of their advantages of convenient opening and closing and high safety performance. However, most of the fully automatic indoor door locks currently on the market have the following defects: [0004] 1...

AI Technical Summary

Problems solved by technology

[0004] 1. A set of bevel gear mechanism is usually used to realize the transmission between the output end of the drive motor and the unlocking shaft. On the one hand, the impact resistance is poor, and it is easy to cause impact damage to the bevel gear mechanism due to the impact force when the drive motor rotates. The service life is not high. If metal gears are used to replace conventional plastic gears, the cost will increase significantly. On the other hand, it is easy to ensure the verticality of the transmission commutation due to the uneven force during transmission, which will affect the transmission performance. smoothness, and aggravate the loss of motor power, usually need to choose a larger motor to realize the drive, and then cause the control box to be bulky, which is not conducive to the installation and use on the interior door

[0005] 2. When the lock cylinder is connected to the control box, it only has a limit fixed in one direction. During use, there is a certain amount of mutual deflection between the two, which will affect the relationship between the unlocking shaft in the control box and the shaft of the lock cylinder in the lock cylinder. Concentricity, and ultimately affect the reliability of the unlocking action
