Folding and fixing device for a seat of an electric walk-substituting vehicle
First Claim
1. A folding and fixing device for a seat of an electric walk-substituting vehicle,the electric walk-substituting vehicle comprising:
- a chassis;
the chassis includes a main part and a footrest part pivotally connected to the main part;
the main part of the chassis having a joining component fixed on each of two sides thereof;
a seat assembly positioned above the main part of the chassis;
the seat assembly being positioned above the main part of the chassis so as to be movable between a raised in-use position and a lowered not-in-use one;
the seat assembly including two connecting rods, which are each pivotally connected at a lower end thereof to one of the joining components on the main part of the chassis;
a steering mechanism pivoted on a front end of the footrest part of the chassis; and
a folding and fixing device for fixing the seat assembly;
the folding and fixing device fixing the seat assembly after the seat assembly is moved to a chosen one of the raised in-use and the lowered not-in-use positions;
the folding and fixing device including;
(a) two position-limiting plates, which are each securely joined on a lower end of one of the connecting rods of the seat assembly;
each of the position-limiting plates having a curved groove on one side thereof, and first and second fixing holes, which are formed on another side of the position-limiting plate, and communicate with the curved groove; and
(b) a pressing and moving mechanism interposed between the joining components fixed on the main part of the chassis;
the pressing and moving mechanism having plural insertion rods;
the insertion rods passing into corresponding said fixing holes of the position-limiting plates through the curved grooves so as to fix the connecting rods of the seat assembly after the seat assembly is moved to a chosen one of the raised in-use and the lowered not-in-use positions.

Abstract
An electric walk-substituting vehicle includes a chassis, a seat assembly pivoted on upper ends of the connecting rods, a pivotal steering mechanism, and a folding and fixing device, which will fix the connecting rods after the seat assembly is moved to either of raised in-use and lowered not-in-use positions; the seat assembly includes connecting rods pivoted on the chassis; the folding and fixing device includes two position-limiting plates, which are secured on the connecting rods to pivot together with the connecting rods; the position-limiting plates each have first and second holes; the folding and fixing device includes a pressing and moving mechanism with two insertion rods; the insertion rods will pass into the first holes to engage the position-limiting plates after the connecting rods are pivoted to the raised in-use position; the insertion rods will pass into the second holes after the connecting rods are pivoted to the not-in-use position.
