Abstract
The utility model relates to a wheelchair, which is characterized in that a wheel is formed by connecting three driving wheels; a balancing frame and a brake guard are arranged on the frame; and the brake guard is connected with the driving wheels. When in use, the wheel of the utility model is formed by connecting the three driving wheels; the three driving wheels are distributed in the shape of equilateral triangle; when climbing over a barrier, the topmost driving wheel makes arc-shaped overturning under the action of push force, thereby reducing the bump rate in the climbing process, and improving equilibrium sense and comfort degree; meanwhile, under the action of the balancing frame, the center of gravity of the wheelchair transfers downwards in the climbing process, thereby increasing the push force, so that the wheel can easily climb over a barrier.
Description
Technical field:
This utility model relates to the technical field of wheelchair, specifically a kind of wheelchair that can leaping over obstacles.
Background technology:
Wheelchair on the market is when throwing over barrier at present, owing to be subjected to the restriction of wheel size, and limited earth-grasping force, balance can be poor when throwing over barrier, sometimes even wheelchair rollover occurs, bring injury to user, especially when crossing greater than the barrier more than the radius of wheel (such as stair), existing Wheelchair structure can't be competent at.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved wheelchair, and it can overcome in the prior art the steadily some shortcomings of throwing over barrier of wheelchair.
To achieve these goals, the technical solution of the utility model is: a kind of wheelchair, and it mainly comprises vehicle frame, is located at balance seat and wheel on the vehicle frame, it is characterized in that: wheel is formed by connecting by three driving wheels, vehicle frame is provided with balancing stand and handle is protected in brake, and brake is protected handle and linked to each other with driving wheel.
Wheel of the present utility model is formed by connecting by three driving wheels during use, three driving wheels are equilateral triangle and distribute, the driving wheel of the top is when throwing over barrier, will under the effect of thrust, do the arc upset, alleviate the amplitude of jolting in the process of crossing, increase equilibrium sense and comfort level, simultaneously under the effect of balancing stand, cross the center of gravity of whole wheelchair is shifted downwards, increased thrust, make throwing over barrier become light and handy easily.
Description of drawings:
Fig. 1 is the structural representation of this utility model one embodiment
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
This utility model mainly comprises vehicle frame 1, is located at balance seat 2 and wheel on the vehicle frame, and its difference with the prior art is: wheel is formed by connecting by three driving wheels, and vehicle frame is provided with balancing stand 3 and brake is protected 4, and brake is protected handle and linked to each other with driving wheel 5.The end that vehicle frame is provided with 6, three driving shafts of driving shaft of three five equilibriums links to each other with vehicle frame, and the other end of three driving shafts links to each other with a driving wheel respectively.Brake is protected being provided with balance liquid depression bar 7, and driving wheel is provided with brake hose 8, and the balance liquid depression bar links to each other with brake hose, when needing brake, only need press brake and protect handle, just can make driving wheel be stuck by the effect of balance liquid depression bar, can't rotate again.Balancing stand is provided with rotatable movable pulley 9.The balance seat is " L " type, and chair back portion is camber line shape, with the comfort level of increase use, and the safety of protection user when crossing higher barrier.The bottom of vehicle frame is provided with a flexible stabilizer 10, can smoothness and the comfort level of wheelchair in the process of advancing, and the place ahead of vehicle frame is provided with a pedal 11.
In force, this utility model can be crossed the following stair of 40cm, because three driving wheels are equilateral triangle and distribute, the driving wheel of the top will be done the arc upset under the effect of thrust when throwing over barrier, alleviate the amplitude of jolting in the process of crossing, increased equilibrium sense and comfort level, simultaneously under the effect of balancing stand, crossed the center of gravity of whole wheelchair is shifted downwards, increase thrust, made throwing over barrier become light and handy easily.
