Electronic Glove Box Latch With Rack-and-Pawl Locking Control

The patent replaces the traditional manual mechanical latch system with an electronically actuated motor-driven system. The motor converts electrical energy to mechanical motion, which is then transmitted through a gear arrangement and rack to move the pawls. This substitution enables automated operation via electronic control signals, significantly improving ease of operation while the modular mechanical transmission components keep the overall device complexity manageable.

The patent introduces a motor as an intermediary device between the electronic control system and the mechanical latch components. The motor serves as a mediator that converts electrical actuation into the mechanical motion required to move the rack and pawls. This intermediary enables seamless integration between electronic control and mechanical locking functions, resolving the contradiction between operational convenience and mechanical simplicity.

The patent employs a dynamic gear arrangement where the gear can rotate to different positions to control the rack's movement. The gear's rotational dynamics enable controlled transition of the pawls between engaged and disengaged states. This dynamic mechanism provides reliable locking through controlled motion while maintaining reasonable device complexity by using standard mechanical components in a configured arrangement.

The patent segments the locking mechanism into distinct functional components: the motor, gear arrangement, rack, and pawls. Each component has a specific function and can be independently analyzed or replaced. This segmentation allows the system to achieve high reliability through specialized components while managing overall complexity by modularizing the design, making each segment relatively simple.
