Description

A kind of high-performance Collapsible wheelchair vehicle

Technical field

The present invention relates to wheel-chair field, especially a kind of high-performance Collapsible wheelchair vehicle.

Background technique

Wheel-chair is a kind of special walk tool for lower limb disability person.Wheel-chair can be divided into according to driving method Combustion-motor-driven wheelchairs and hand wheel-chair；Hand-propelled tricycle, so adapting to various roads traveling, mainly exists because its wheel footpath is larger The outdoor walking-replacing tool as relatively long distance, and can suitably fill cultivation cargo；It has the characteristics that travel speed is very fast, laborsaving. Combustion-motor-driven wheelchairs have backrest, handrail and safety belt limit, to keep the body steadiness of user, and have short distance hand mobile Device, to move to safety when failure manually or not hinder traffic location.Mobility strong, fuel supplement be convenient, easy to operate etc. Feature.

With era development and scientific and technological level progress, combustion-motor-driven wheelchairs are fabricated to the form of multiplicity in existing market, Meet market use demand, but considered from all various aspects such as comfort level, structural strength, degree easy to use, existing technology is still deposited In many technological deficiencies: (1) being directed to the wheel chair handle of wheel-chair.The grip structure of wheel-chair is fixed form in the prior art, Wheel-chair handle when idle seems extra, and occupied space influences beauty, and be easy to cause the situation of scratching.(2) it is directed to wheel-chair Folding property.The prior art is typically all to realize left and right folding using crossbar or fold, and reduces the space of left and right directions, It is not folded in wheel-chair short transverse, the overall volume of wheel-chair is still larger, is difficult to the wheel-chair to be placed on spatial altitude smaller Place, cause wheel-chair store limitation it is strong.(3) it is directed to wheel-chair cushion heat dissipation performance.Circuit heat passes through in cushion It is transmitted in cushion simultaneously and human contact, transmit hot to human body progress leads to sense of discomfort；Environment temperature is higher simultaneously, does not have in cushion There is effective radiator, people, which is sitting on cushion, easily to perspire；Structure is not aerated to wheel-chair cushion in the prior art, is made It is low with personnel's ride comfort.(4) for the fixed device of the controller of wheel-chair.Controller is set as fixed shape in the prior art The angle of formula, controller level is non-adjustable, and user of service cannot control in use according to the height of oneself, sitting posture adjustment The controller level of the angle of device handle, fixed form limits the convenience of use process, affects the use of user of service Comfort level；When user of service is chronically under more awkward mode of operation, the misoperation of Yi Yinqi user of service or accidentally behaviour Make, or even influences the safety of user of service.(5) it is directed to the front wheel link construction of wheel-chair.Wheelchair front wheel is consolidated in the prior art Determine connection type fixed front-wheel vertical shaft in such a way that front-wheel covers pipe sleeve bearing, and front-wheel casing is to be directly welded at wheel-chair vehicle On frame, cause the deflection of front-wheel casing in process bigger, while weld seam influences the beauty of integral body.
