Problems solved by technology

[0002] In the prior art, there is only one motor component of the electronic smart door lock, and the reliability is not high. Once the motor is damaged, the entire electronic smart door lock cannot be used, which is risky and expensive
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

Abstract

The invention provides a motor assembly for an intelligent electronic door lock. According to the motor assembly, structures of a cover plate (1), two small gears (2), a gear shaft (3), a motor shell (4), two same motors (5), a torsion spring (6), an arc push plate (7), a front push plate (8), a rear push plate (9) and a transverse rod (10) are designed cleverly, especially the two same motors work independently, and the risk caused by working stop of the motor assembly due to damage of the motors can be lowered through the redundant design that one motor is available, and the other motor is standby. Besides, the top end of the transverse rod of the gear shaft is designed to be in a circular cone shape, due to the profile of the transverse rod of the gear shaft, the top face of the transverse rod is a point and makes less contact with a spring wire, the spring wire can slide off freely when the transverse rod penetrates through the spring wire alternately, the situation that the spring wire of the torsion spring is stuck by the transverse rod is avoided, and the normal state is achieved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a motor assembly for an electronic intelligent door lock. Background technique [0002] In the prior art, there is only one motor component of the electronic smart door lock, and the reliability is not high. Once the motor is damaged, the entire electronic smart door lock cannot be used, which is risky and expensive. 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. Burnout problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a motor assembly for an electronic smart door lock. [0004] The motor assembly for the electronic intelligent door lock of the present in...
