Description
Technical field
This utility model relates to a kind of electric stair-climbing wheel chair chassis, belongs to wheelchair design field.
Background technology
More than 100 year has been had in the world to the research of stair-climbing wheel chair and barrier getting over mechanism, also successively a variety of schemes is proposed, common are crawler type, planet gear type and lower limb foot formula, on general significance, crawler-type wheel chair is bulky and due to the defect in principle, be easy to cause the damage to stairway step, the general also more complicated of lower limb foot formula, and control system is loaded down with trivial details, planet gear type simply and easily realizes due to principle, all have superiority from every side, common planetary wheel construction has two degree of freedom, if the motion making planetary gear have to determine, need two inputs determined, and in all kinds of planetary gears used at present, a motor is all used to drive the central gear of planetary gear, namely only an input determined is given, another one degree of freedom relies on the situation on ground to retrain, the one degree of freedom of this drive train is not by manual control, but adjust according to surface conditions, theory analysis and Force Calculation show, when the attachment coefficient on wheelchair tire and ground is less, likely there is the situation of skidding in star wheel structure, successfully can not overturn star-wheel mechanism Lai Pa building, so it is particularly important to design a kind of new structure.
Summary of the invention
The purpose of this utility model is: for the defect of prior art, provides a kind of electric stair-climbing wheel chair chassis, realize when climbing building initiatively by axle and star-wheel mechanism locked, thus realize the upset Lai Pa building of star-wheel mechanism, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A kind of electric stair-climbing wheel chair chassis, comprise symmetrically arranged star-wheel mechanism, the star-wheel of star-wheel mechanism arranges gear one, the centrage of star-wheel mechanism arranges central gear and this central gear respectively with corresponding gear one cooperation, the centrage that central shaft is arranged on star-wheel mechanism adopt spline to be fixedly connected with the star-wheel mechanism of both sides, travelling gear one is set in the middle part of central shaft, power transmission shaft symmetry is enclosed within central shaft both sides and is connected by bearing to each other, one end of power transmission shaft is fixedly connected with by spline with corresponding central gear, the other end arranges travelling gear two, driven pulley is flexibly connected star-wheel mechanism by connecting rod and forms overall electric stairs-climbing wheelchair chassis.
In aforesaid a kind of electric stair-climbing wheel chair chassis, described travelling gear one is consistent with the parameter of travelling gear two and quantity is equal.
In aforesaid a kind of electric stair-climbing wheel chair chassis, middle train is set between gear one and central gear.
Owing to have employed technique scheme, compared with prior art, this utility model realizes power and independently to drive in star wheel structure star-wheel rotation and star-wheel around the revolution of star wheel structure centrage, overcome this slippery conditions of planetary gear structure in general stair-climbing wheel chair chassis, also planetary wheeling mechanism is controlled in Shi Pa building process better, realize when climbing building initiatively by axle and star-wheel mechanism locked, thus realize the upset Lai Pa building of star-wheel mechanism.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: a kind of method for designing of electric stair-climbing wheel chair chassis, the method adopts star-wheel mechanism as the active walking basal seat of this electric stairs-climbing wheelchair, and the walking manner of this star-wheel mechanism comprises star-wheel rotation realizes the movement of electric stairs-climbing wheelchair on level ground, the function of electric stairs-climbing wheelchair at speeling stairway is realized around the revolution of star-wheel mechanism centre of gyration line with star-wheel, above-mentioned two kinds of walking manners adopt to arrange respectively on the centre of gyration line of star-wheel mechanism and drive central gear and central shaft and independent of one another, central gear is wherein driven to drive star-wheel rotation, central shaft drives star-wheel mechanism to realize the revolution of star-wheel around star-wheel mechanism centre of gyration line, realize motor by electromagnetic clutch again and drive central shaft and central gear respectively.
Wherein specific embodiment is for comprising symmetrically arranged star-wheel mechanism, the star-wheel of star-wheel mechanism arranges gear one, the centrage of star-wheel mechanism arranges central gear and this central gear respectively with corresponding gear one cooperation, the centrage that central shaft is arranged on star-wheel mechanism adopt spline to be fixedly connected with the star-wheel mechanism of both sides, travelling gear one is set in the middle part of central shaft, power transmission shaft symmetry is enclosed within central shaft both sides and is connected by bearing to each other, one end of power transmission shaft is fixedly connected with by spline with corresponding central gear, the other end arranges travelling gear two, driven pulley is flexibly connected star-wheel mechanism by connecting rod and forms overall electric stairs-climbing wheelchair chassis.
A kind of electric stair-climbing wheel chair chassis constructed by said method, as shown in drawings, comprise symmetrically arranged star-wheel mechanism 1, the star-wheel 2 of star-wheel mechanism 1 arranges gear 1, the centrage of star-wheel mechanism 1 arranges central gear 4 and this central gear 4 coordinates with corresponding gear 1 respectively, middle train 11 is set between gear 1 and central gear 4, the centrage that central shaft 5 is arranged on star-wheel mechanism 1 adopt spline to be fixedly connected with the star-wheel mechanism 1 of both sides, travelling gear 1 is set in the middle part of central shaft 5, power transmission shaft 7 symmetry is enclosed within central shaft 5 both sides and is connected by bearing to each other, one end of power transmission shaft 7 is fixedly connected with by spline with corresponding central gear 4, the other end arranges travelling gear 28, driven pulley 9 is flexibly connected star-wheel mechanism 1 by connecting rod 10 and forms overall electric stairs-climbing wheelchair chassis, this travelling gear 1 is consistent with the parameter of travelling gear 28 and quantity is equal.
Its operation principle is, when level land travels, motor drives travelling gear two, power is passed to central gear by power transmission shaft by travelling gear two, power passes on the gear one of star-wheel by idler gear by central gear, thus drive star-wheel rotation, even if wheelchair smooth-ride, climbing the building stage, by connecting electromagnetic clutch, make motor start to drive travelling gear one, thus drive central axis, and central shaft is fixedly connected with by spline with the star-wheel mechanism of both sides, then now star-wheel mechanism can complete upset thus carry out climbing building motion.
