Dynamic return structure.
Housing portion folds：Gear is folded under collapsible spring effect while being caught in the tooth socket of upper joint and hypozygal,
So that lower articular is in fastening state.When returning the vehicle to the garage and knock off, block of returning the vehicle to the garage and knock off up is pulled, drive folds steel cable movement.Fold steel cable
Rope gland be fixed on motionless in the tooth socket of hypozygal, can will fold gear when fold steel cable and be straightened when is pressed onto hypozygal
Gear grooved in, fold gear be detached from upper joint tooth socket, lower articular fastening state disappear.The shape for block of returning the vehicle to the garage and knock off is pulled in holding
State up pushes away seat down tube, and seat skeleton drives mounting connection sheet and mounting pipe to fold by four-bar linkage structure, until under seat
Pipe reclines completely with seat upper tube.When seat is unfolded, by the reverse operating for the process of returning the vehicle to the garage and knock off, the block that will finally return the vehicle to the garage and knock off is put down, and is received
It closes gear to be pressed back under the action of collapsible spring while with the tooth socket of the tooth socket of upper joint and hypozygal engaging, is formed and fixed
Structure.
Frame section folds：A, the tooth socket for pulling the pull rod that returns the vehicle to the garage and knock off that the gear that returns the vehicle to the garage and knock off is driven to be detached from support joint, at this time support are closed
Section engages to form one under the action of tumbler gear with extrinsic articulation, and handle assembly under gravity around intrinsic articulation due to turning downwards
It is dynamic, it drives support joint and housing portion thereon to rotate together, realizes and fold.
B, it is lifted up when returning the vehicle to the garage and knock off pull rod, while can pull the lower steel cable that returns the vehicle to the garage and knock off that grab is driven to be detached from and the engaging of slide axis
State, front foot group is close toward the rotation of rear foot tube direction under the effect of gravity, and slide slides on the sliding slot of rear foot tube, to realize
Vehicle frame returns the vehicle to the garage and knock off.
The present invention by seat down tube, fold steel cable, hypozygal, upper joint, fold gear, collapsible spring and block of returning the vehicle to the garage and knock off
Equal components form the retrieving structure of housing portion, and by returning the vehicle to the garage and knock off, block tenses collapsible spring, make to fold gear and upper joint disengaging
Engaging realizes that seat down tube all can be to realize to fold or be unfolded by ganged movement with rotary folding, other components；And by seat
Frame support tube, intrinsic articulation, support joint, the gear that returns the vehicle to the garage and knock off, the spring that returns the vehicle to the garage and knock off, the pull rod that returns the vehicle to the garage and knock off, the components such as steel cable that return the vehicle to the garage and knock off up and down form vehicle
The retrieving structure of frame part tenses the steel cable that returns the vehicle to the garage and knock off up and down by pulling the pull rod that returns the vehicle to the garage and knock off, intra-articular gear is made to release engaging, joint
Both can rotate in the forward direction, can also reversely rotate, to realize both can forward direction return the vehicle to the garage and knock off, the effect that also can reversely return the vehicle to the garage and knock off.And it entirely returns the vehicle to the garage and knock off
Process can be easy to operate, time saving and energy saving by manually individually operated, and operation can be completed in one hand, be very beneficial for old man and
Women uses, and folds the diminution of folded state lower volume, easy to carry.
