When backrest 600 needs to be rotated clockwise to the second target location 603 from reference position 601, backrest
600 center of gravity moves from high to low, and driving device 600 (motor) drives backrest 600 (mechanical arm) to revolve clockwise
Turn, transmission device 400, which is also driven, to be rotated clockwise.At this point, fixture block 403 pushes two limited blocks 1022,1023, from
And the first rotating device 100 is driven to rotate clockwise.Third turntable block 4011 slides in the first arc slide opening 2023, and second
For turntable 202 completely not by thrust, the second rotating device 200 is stationary.Since the inner end of scroll elastic component 300 is fixed
The first rotating device 100 is connected to, outer end is fixedly attached to the second rotating device 200, therefore scroll elastic component 300 can be sent out
Raw deformation, generates curling, and the gravitional force of backrest 600 is converted into the elastic potential energy of scroll elastic component 300.
When backrest 600 needs to be rotated back to reference position 601 counterclockwise from the second target location 603, seat leans on
The center of gravity of the back of the body 600 is hoisted movement by lower, and driving device 600 (motor) drives backrest 600 (mechanical arm) to revolve counterclockwise
Turn, transmission device 400 is also driven generation rotation counterclockwise.When backrest 600 returns to reference position 601, the first rotating dress
It puts 100 and rotates counterclockwise 90 degree, scroll elastic component 300 gradually restores hence shape, the elastic potential energy of scroll elastic component 300
The gravitional force of backrest 600 is converted into, so as to reduce acting of the driving device 600 to backrest 600, reduces motor energy
Consumption.
In the center of gravity from high to low in moving process of backrest 600, when backrest 600 in vertical plane along suitable
