Description
Technical field
This utility model relates to a kind of damping anti-tilt device of electric wheel-chair vehicle parts, particularly electric wheel-chair vehicle.
Background technology
Present electric wheel-chair vehicle car is generally the four-wheel structure, and to increase its stability, its driving can adopt front-wheel drive also can adopt rear wheel drive.The steering flexibility of four-wheel electric wheel Wheel-chair is poor, in order to improve steering behaviour, two-wheel occurred and has driven electric wheel-chair vehicle.But there are the following problems for existing electric wheel-chair vehicle: when (1) electric wheel-chair vehicle rotates in advance turning or original place, because action of centrifugal force, it is far away that the center of rotation of feasible wheel Wheel-chair departs from the human body center, not only takes advantage of a person uncomfortable, and less stable, easily tipping.(2) damping effect of known electric wheel-chair vehicle is relatively poor, also can cause in advancing unstablely and jolt, and makes and takes advantage of a person uncomfortable.(3) when promoting empty wagons with manpower, promote again after need pulling clutch, very loaded down with trivial details, and forget easily clutch is turned back original position, cause when taking advantage of once more wheelchair to be failure to actuate or to slide.
The utility model content
The problem that the moving present electric wheel-chair vehicle of pin exists, the purpose of this utility model is to provide a kind of electric wheel-chair vehicle damping anti-tilt device, and feasible electric wheel-chair vehicle damping and the good stability that uses this driving device is easy to use, safety and comfort.
The electric wheel-chair vehicle damping anti-tilt device that this utility model provides comprises motor, tooth case, driving wheel, it is characterized in that: a support bar is installed at the tooth upper box part, the support bar front portion is bent downwardly, and there is an axis hole end, by an elastic shock-absorbing device auxiliary wheel is installed.
Above-mentioned elastic shock-absorbing device can comprise the connecting plate of two bendings, and the connecting plate bending part has an axis hole, and an axle passes the axis hole of above-mentioned support bar end, two connecting plate bendings upwards is fixed on the two ends of axle by the axis hole of connecting plate bending part; Two connecting plates end backward is fixed together by a wheel shaft, and auxiliary wheel is installed on the wheel shaft; The center of a torque spring be in connecting plate bending axis hole below, an end is fixed on a connecting plate end backward, the other end is fixed on the support bar.
At described two connecting plates end forward an anti-tip wheel can also be installed.
Can be inserted with a damping pin rod at described support bar middle part, yielding rubber is arranged in the middle of the pin rod.
During use, electric wheel-chair vehicle damping anti-tilt device of the present utility model is installed on the front portion or the rear portion of electric wheel-chair vehicle, about each one.Be connected with the vehicle frame of electric wheel-chair vehicle by the damping pin rod on the support bar.When nobody takes advantage of, have only the auxiliary wheel of electric wheelchair to land, driving wheel does not land, man-hour on seat, driving wheel just can land under people's body weight effect, forms six and takes turns and land.When manpower promoted empty wagons, two driving wheels do not land, and need not pull clutch and just can advance, and were easy to use like this.In advancing, electric wheel-chair vehicle slows down or when stopping, take advantage of person's center of gravity reach, make the auxiliary wheel on ground, top be subjected to bigger power, support bar and the torque spring that link to each other with auxiliary wheel this moment are stressed, play the buffer shock-absorbing effect, when pressure is bigger, the anti-tip wheel of support bar front contacts to earth, play a supporting role, make electric wheel-chair vehicle can further not lean forward, guaranteed to take advantage of a person safety.In addition,, when electric motor car leans forward or jolt, also can play buffer shock-absorbing effect, make and take advantage of a person more comfortable vehicle frame owing on the damping pin rod on the support bar, yielding rubber is arranged.
Description of drawings
Fig. 1 is the part axonometric drawing in bulk of electric wheel-chair vehicle damping anti-tilt device;
Fig. 2 is an electric wheel-chair vehicle damping anti-tilt device part assembly drawing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments electric wheel-chair vehicle damping anti-tilt device of the present utility model is described further.
With reference to Fig. 1 and Fig. 2, electric wheel-chair vehicle damping anti-tilt device of the present utility model comprises driving wheel 1, motor 2, support bar 3, damping pin rod 4, auxiliary wheel 5, connecting plate 6, anti-tip wheel 7, torque spring 8, connecting plate 9 and tooth case 10.Motor 2 links together with tooth case 10, and driving wheel 1 is installed on the tooth case 10, and support bar 3 is fixed on above the tooth case 10.Support bar 3 anterior bendings downwards, there is axis hole the end, connecting plate 6 also has a bending with connecting plate 9, axle 11, wheel shaft 12 and fixed axis 13 are arranged on connecting plate 6, the axis hole that axle 11 passes support bar 3 front ends, connecting plate 9 are fixed on the axle 11 of connecting plate 6, and fixed axis 12 is positioned at and is connected with connecting plate 9 below the support bar 3, wheel shaft 12 1 ends and connecting plate 9 are fixing, and the other end is installed auxiliary wheel 5.Torque spring 8 one ends are positioned on the support bar 3, and the other end is positioned on the connecting plate 9.Anti-tip wheel 7 is installed between connecting plate 6 and connecting plate 9 front ends.The damping pin rod 4 that has yielding rubber assigns into support bar 3 middle parts.
During use symmetric two electric wheel-chair vehicle damping anti-tilt devices are installed in both sides below electric wheelchair vehicle frame front portion or the rear portion, insert below the vehicle frame damping pin rod upper end, fix in addition by the through hole and the vehicle frame of support bar back, making electric wheel-chair vehicle damping anti-tilt device install latter two auxiliary wheel lands, two driving wheels omit overhead, and two anti-tip wheels do not land yet.
When taking advantage of a person to take electric wheel-chair vehicle, composedly, but two anti-tip wheels still do not land under two driving wheels.Be six to take turns and land this moment, and electric wheelchair can be advanced under motor-driven.If the wheel Wheel-chair is turned, is slowed down or stops, during occupant's center of gravity reach, can make the connecting plate of auxiliary wheel and torque spring stressed, the elasticity of spring plays vibration damping and cushioning effect, leans forward when serious, and the anti-tip wheel support that lands prevents to tumble and causes danger.In addition, the vibration isolation rubber on the vibration damping pin rod of support bar and vehicle frame junction also can play the effect of buffering and absorbing vibration, the integral vibration damping better effects if of electric motor car, and the occupant is more comfortable.
