Foot, is susceptible to the situations such as fracture.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide a kind of convenience type wheelchair,
Easy to use, ride comfort, firm and durable.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of convenience type wheelchair, parallel including two groups
The side supports assembly arranged, is provided with crossbar assembly between two groups of side supports assemblies；Described side supports assembly includes
Backrest support rods and foot-operated support bar, backrest support rods and foot-operated support bar be arranged in parallel, backrest support rods and foot-operated support bar
Between be provided with midfoot support bar and lower support bar, the two ends of midfoot support bar and lower support bar respectively with backrest support rods
Being vertically arranged with foot-operated support bar, backrest support rods top is provided with handlebar stem, and the middle part of foot-operated support bar connects foot-driven lever,
The top of foot-driven lever connects pedal；Described crossbar assembly includes be arranged in parallel two intersections that intersection is rotationally connected
Bar, the two ends of crossbar are respectively arranged with sleeve pipe and setting of casing, and upper sleeve pipe is socketed with midfoot support bar, and setting of casing props up with bottom
Stay tube is socketed；Described side supports assembly also includes two shanks be arrangeding in parallel, backrest support rods and foot-operated support bar
Sidepiece is respectively arranged with a grafting cylinder, and the lower end of shank is plugged in grafting cylinder；It is provided with between said two shank
Middle part backplate, the top of two shanks connects by top connecting rod is fixing；The stage casing of described shank is provided with segmental arc,
Being provided with elastic supporting bar in the arc opening of segmental arc, the stage casing of midfoot support bar is provided with arc accumulation of energy section, arc accumulation of energy
The length that radian is shank of section and the ratio of the arc opening length of segmental arc.
Optimizing, above-mentioned convenience type wheelchair, be provided with metal stay cord in the arc opening of described arc accumulation of energy section, metal draws
Metal ball it is socketed with on rope.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.The design of the application
Reduce the weight of car load, can be with folding storage, convenient trip uses.Side supports assembly is set to two by the design of the application
Part grafting forms, convenient use.And by the way of grafting, the upper and lower of side supports assembly is separated so that
The lower part stressing conditions of support component is simple, the convenient bottom force structure adjusting side supports assembly, improves support strength.This
The design of application arranges segmental arc in the stage casing of shank, for absorbing vibrational energy by elastic deformation, improves comfort level.For
Coordinate the design of segmental arc, improve supporting degree and convenient absorb vibrational energy, arc being set in the stage casing of midfoot support bar and stores
Energy section, prevents two segmental arcs from occurring resonance to affect the absorption of vibrational energy.Calculate through digital modeling, arc accumulation of energy section
The ratio of arc opening length of the length that radian is shank and segmental arc time, resonance can be preferably minimized.And arrange
Metal stay cord and metal ball, by the shock absorption resonance energy of metal ball.
