A spiral back-clutch device based on a dual-motor module

Abstract

The invention provides a spiral type clutch return device based on double motor modules. The spiral type clutch return device comprises the double motor modules and a spiral type clutch return module. The risk that the work of the double motor modules is stopped when motors are damaged is lowered through the redundancy design that two same motors independently work, one motor is used and the other motor is used for standby application. The top end of a transverse shaft of a gear shaft is designed into a circular cone shape, the situation that A torsional spring wire is stuck with a transverse rod can not happen, and the torsional spring can return to the normal state. The spiral type clutch return module is arranged on an indoor rear face plate, and therefore when a front face plate is damaged and detached, a door block can still not be opened. The spiral type clutch return module can only rotate in a single direction; when the spiral type clutch return module rotates reversely, a square steel sleeve and an inner handle rotation piece are separated through spiral faces on the inner handle rotation piece and the square steel sleeve, the inner handle rotation piece can not be rotated through friction force, safety is high, and by means of the design, rapid locking can be conducted both indoors and outdoors.

Description

technical field [0001] The invention belongs to the technical field of intelligent lock products, and in particular relates to a spiral clutch device based on a double motor module. Background technique [0002] At present, most of the clutch mechanisms of electronic door locks on the market are located on the front panel of the door lock or inside the lock body. The structure of the door lock with the clutch on the front panel is simple, but the front panel is damaged, and it is easy to open the door lock when the front panel is removed; the lock body of the door lock with the clutch inside the lock body is an electric lock body, and there is a signal on the lock body Wires, power supply lines, and the installation of the lock body are cumbersome, and due to the addition of electrical components, the reliability of the lock body decreases. Moreover, in the prior art, there is only one dual-motor module of the electronic smart door lock, and the reliability is not high. Onc...

Problems solved by technology

The structure of the door lock with the clutch on the front panel is simple, but the front panel is damaged, and it is easy to open the door lock when the front panel is removed; the lock body of the door lock with the clutch inside the lock body is an electric lock body, and there is a signal on the lock body Cables, power supply lines, the installation of the lock body is more troublesome, and due to the addition of electrical components, the reliability of the lock body is reduced

Moreover, there is only one dual-motor module in the electronic smart door lock in the prior art, and the reliability is not high. Once the motor is damaged, the clutch mechanism cannot be used, and the risk is high and the cost is high.

Moreover, during the movement of the motor pushing plate in the prior art, since the top of the horizontal axis is a plane and has a large contact area with the spring wire, the cross bar may block the torsion spring spring wire, causing the motor to be unable to rotate, and the motor is stuck. burn out problem
