AI Technical Summary

Technical Problem

The existing controller is too large, which limits the number of flexible shafts that can be installed, making it impossible to meet the needs of customer vehicle models. It is also not comfortable to operate, has a low leverage ratio, and cannot simultaneously connect multiple cables or rods to achieve torque transmission.

Method used

Design a controller with limit braking and clutch, which adopts a structure of push rod, pawl, ratchet plate and limit cylindrical pin. The push rod is connected to the pawl, the pawl is hinged to the handle welded part, the ratchet plate is hinged to the base frame, and a spring is installed on the push rod to realize torque transmission and limit function.

Benefits of technology

It enables comfortable operation in a small space, has a large leverage ratio, and can hang multiple cables or rods at the same time to meet the assembly needs of various vehicle models.
