Description
Technical field
This utility model relates to a kind of electric wheelchair, belongs to daily living article field.
Background technology
Electric wheelchair is the important walking-replacing tool that shank has the old people of group of handicapped or legs and feet inconvenience, existing electric wheelchair move mode is divided into and advances, retreats and turn, and turn, generally to just can complete through a large radian, for traveler, in some narrow regions, the operation that is difficult to turn, and if directly carry out back operation, danger is very high, to trip, makes troubles.In addition, when running into emergency situations, as electric wheelchair knocks the emergent barrier in the place ahead, it is too late that operator often reacts, and has little time motor to stop, and motor driving wheel chair continues forward, to occupant, causes larger injury.
Comparatively convenient when existing electric wheelchair is advanced on smooth road surface, when comparatively jolt in road surface, because wheel is less and damping property is poor, cause the people who takes very uncomfortable, even health is worked the mischief.
Utility model content
According to above the deficiencies in the prior art, the purpose of this utility model is: a kind of comfortable electric wheelchair is provided, and comfortableness is good, and steering behaviour is good, and trip is convenient, easy to use and flexible, and safety coefficient is high.
Comfortable electric wheelchair described in the utility model, comprise seat support and the folding chair back, handrail is equipped with in seat support both sides, seat bottom is equipped with two front-wheels and two trailing wheels, seat support front end is equipped with pedal assembly, pedal assembly comprises the framework that is fixed on seat support and the front running board hinged with frame front end, framework rear side is installed a connecting rod, small end matches with the microswitch being arranged on seat support, connecting rod lower end and front running board rear end are hinged by bearing pin, left drive motors is installed in trailing wheel inner side, left side, right drive motors is installed in right side rear wheel inner side, left drive motors, between right drive motors and seat support, damping assembly is housed, one controller is arranged on a side handrail, left drive motors, right drive motors and microswitch are connected with controller by circuit respectively.
Left drive motors drives left side rear wheel movement, right drive motors drives right side rear wheel motion, because left and right two trailing wheels adopt independently drive system separately, therefore the travelling performance of trailing wheel is splendid, can carry out 360 °, original place left and right turn, in some narrow spaces, can easily complete commutation, to user, bring convenience.Pedal assembly matches with microswitch, when launching front running board, on the rear end drivening rod of front running board, moves, and small end and microswitch are connected, and wheelchair energising can normally be moved.When electric wheelchair knocks suddenly the place ahead barrier, front running board turns under the effect of impact force, and drivening rod moves down, and connecting rod power-off separated with microswitch, avoids drive motors to remain in operation, and causes more major injury.By damping assembly is set, when advance in the road surface of jolting at some, the vibration that rear wheel is delivered to base reduces greatly, makes the people who takes feel more comfortable.
Described left drive motors and right drive motors one side are equipped with respectively clutch, the clutch of both sides is connected with clutch lever lower end by connector, clutch lever is movably arranged in the groove of a side handrail, its upper end protrudes from handrail upper surface, by clutch lever solenoidoperated cluthes, make drive motors separated with wheel, rider can rotate trailing wheel by hands moves wheelchair, plays the object of taking exercises, and occupation mode is flexible.
Described clutch lever and controller lay respectively on two side handrails, handled easily.
Described damping assembly is comprised of the column elastomer of inner side and the spring that is sleeved on elastomer outside, and elastomer and spring play the effect of vibration damping, good damping result jointly.
Described rear wheel diameter is front wheel diameter 3～8 times, trailing wheel highest point is less than 30cm apart from handrail upper surface distance, when road bump, because the diameter of trailing wheel is larger, therefore trailing wheel central rotating shaft Oscillation Amplitude significantly reduces, thereby play vibration damping object, simultaneously higher trailing wheel facilitates under manual mode and grasps.
On the handrail of both sides, audio amplifier is housed, can in trip, listens to the music, occupant is loosened, be conducive to health preserving.
On described seat support, spfa cushion is housed, ride comfort.
The described chair back is provided with nanometer zone of heating, and nanometer zone of heating is connected with controller by circuit, by nanometer zone of heating, heats, and occupant's back is played to massage effect, is conducive to patient's physical rehabilitation.
The described chair back is provided with cervical region and back-beating massage machine, can massage cervical region and back.
Described controller is provided with wireless signal receiver, the supporting remote controller of wireless signal receiver, wireless signal receiver can be infrared signal or Bluetooth signal receptor, for the severe patient that cannot oneself operate, nurse personnel can carry out Long-distance Control, alleviate work load.
Compared with prior art, the beneficial effect the utlity model has is:
This comfortable electric wheelchair is by arranging damping assembly and increasing rear wheel diameter, and the vibration that rear wheel is delivered to base reduces greatly, and comfortableness is good; Left drive motors and right drive motors are controlled trailing wheel 360 °, original place rotation to the left or to the right, the operation of also can turning in narrow space, and steering behaviour is good, makes occupant's facility of going on a journey; By front running board rear end is set, match with microswitch, when knocking the barrier in the place ahead suddenly, the moving connecting rod of front running board upper turnover-tape leaves microswitch, deenergization, left drive motors and right drive motors shut down, and prevent from causing larger injury, and safety coefficient is high; Pull clutch, can be exchanged into artificial mode, easy to use and flexible.
