Detailed Description
The utility model provides a disabled person's automobile driving auxiliary device, includes control handle 1, control handle 1 bottom is connected with base 2 through the pivot, and base 2 is fixed with the guide rail of car seat through mount 3. The specific mounting and fixing method comprises the steps of firstly dismounting mounting bolts at the front ends of two guide rails of the automobile seat, then placing the fixing frame below the seat guide rails, and then locking and fixing the fixing frame by the mounting bolts of the automobile seat guide rails.
The operating handle 1 is connected with a brake accelerator control assembly device, and the brake accelerator control assembly device comprises a first one-way transmission mechanism 4 connected with an automobile brake pedal 5 and a second one-way transmission mechanism 6 connected with an automobile accelerator pedal 7. The first one-way transmission mechanism and the second one-way transmission mechanism can adopt various forms of one-way transmission, and the modes of sleeves, chains or ratchets can be adopted. The scheme in this example is as follows:
