Electronic Lock Dislocation Transmission Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic locks face damage and reduced service life due to reverse rotation of the electric motor during manual operation, which can occur when users lock or unlock the lock manually.
Innovation Solution
A dislocation transmission mechanism is integrated into the electronic lock, featuring a first dislocation member with an arc opening and a second dislocation member with a protrusion, preventing the electric motor from reversing by selectively engaging and disengaging to prevent motor reversal during manual operation while allowing normal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is allowed on the electronic lock, then ease of operation is improved, but the electric motor may revolve reversely causing damage and reducing service life
Solution Approach 1:
A dislocation transmission mechanism is introduced as an intermediary between the manual operation components (turn piece, cylinder connecting spindle) and the electric motor. This mechanism includes a first dislocation member coupled with the turn piece and cylinder connecting spindle, and a second dislocation member engaged with the first bevel gear, featuring a protrusion that selectively engages with engaging portions on the first dislocation member. During manual operation, the dislocation transmission mechanism allows motion transmission when engaged, but prevents reverse rotation from reaching the motor by dislocating the transmission path, thus protecting the motor while maintaining manual operability.
2Reliability
If the dislocation transmission mechanism is engaged to prevent motor reversal, then motor protection is improved, but transmission of driving force during normal operation may be affected
Solution Approach 1:
The dislocation transmission mechanism employs dynamic engagement and disengagement between the protrusion and engaging portions. During normal electric operation, the protrusion engages with the engaging portions to transmit driving force from the first bevel gear to the turn piece and cylinder connecting spindle. During manual operation that would cause reverse motor rotation, the mechanism dynamically dislocates to prevent reverse force transmission. This dynamic state change allows the system to adapt between protection mode and operation mode, ensuring both motor protection and operational efficiency.

Function Achieved in This Case
The mechanism effectively protects the electric motor and transmission components from reverse rotation, extending their service life without hindering manual or electric operation of the lock.
Implementation Method 1
a dislocation transmission mechanism including a first dislocation member coupled with the turn piece and the cylinder connecting spindle and having an arc opening, and a second dislocation member engaged with the first bevel gear and having a protrusion, in which the protrusion is configured to extend into the arc opening, such that when the protrusion is engaged with either a first engaging portion or a second engaging portion at two ends of the arc opening, the first dislocation member is driven by the second dislocation member

The present invention relates to an electronic lock. The electronic lock includes a turn piece coupled with a cylinder connecting spindle; an electric motor connected with a first bevel gear; and a dislocation transmission mechanism including a first dislocation member coupled with the turn piece and the cylinder connecting spindle and having an arc opening, and a second dislocation member engaged with the first bevel gear and having a protrusion, in which the protrusion is configured to extend into the arc opening, such that when the protrusion is engaged with either a first engaging portion or a second engaging portion at two ends of the arc opening, the first dislocation member is driven by the second dislocation member, and when the first dislocation member is in motion within a void range defined by the arc opening, the first dislocation member fails to drive the second dislocation member.
