Abstract
The utility model discloses an electric wheelchair, and belongs to the technical field of wheelchair design and manufacturing. According to the structure of the electric wheelchair, a rocker controller is arranged at the front end of a frame, front servo steering wheels are arranged at the lower end of the frame, a direct-drive low-speed direct-current magneto is connected with a brake, the brake is connected with a brake cylinder, a lithium battery is connected with the direct-drive low-speed direct-current magneto, an automatic brake control box is arranged in the middle of the frame, and the automatic brake control box is connected with an inflation and deflation switch. Due to the fact that the direct-drive low-speed direct-current magneto serves as a power drive mechanism, transmission efficiency is improved, electromagnetic coils which are charged for a long time do not exist, consumption of a power supply is reduced, and braking is sensitive, reliable and safe due to the fact that pneumatic braking is adopted.
Description
Technical field
This utility model belongs to wheelchair design and manufacturing technology field, is specifically related to a kind of long service life, and climbing capacity is strong, the electric wheelchair that energy consumption is low.
Background technology
Wheelchair is the walking-replacing tool that old people or individuals with disabilities commonly use, and is divided into manual wheelchair and electric wheelchair, and manual wheelchair is due to inconvenient operation, effort, number of users reduces gradually, and is although present electric wheelchair is easy to operate, laborsaving, but its energy consuming ratio is larger, maintenance is inconvenient, and the brake energy consumption is large, brakes not firm, this uses for some old peoples is not easily, easily causes vehicle accident yet.
The brake of electric wheelchair at present has the brake rubber block of employing hand-operated brake, for the old people, use inconvenience, brake dangerous, more a kind of worm and gear is arranged, by mechanical self-latching, this kind energy consumption is large, and after wearing and tearing, self-lock ability reduces also dangerously, and electromagnetic brake, solenoid power are large, energy consumption is high, and the brake weight size is decided by the coil power size.
Present electric wheelchair gross weight generally more than 45 kilograms, adds the weight of battery, makes electric wheelchair be not easy to move, and the increase of gross weight also makes electric wheelchair more consume energy, and course continuation mileage is low, generally at 12～20km.
The utility model content
This utility model is high for present electric wheelchair energy consumption, and climbing capacity is low, and the problem that safety is low proposes a kind of electric wheelchair.
A kind of electric wheelchair, the front end of vehicle frame 2 is provided with rocking rod controller 1, the lower end is provided with front follow-up steering wheel 5, directly driving low-speed DC magneto 8 is connected with brake 7, brake 7 is connected with brake cylinder 6, lithium battery 9 with directly drive low-speed DC magneto 8 and be connected, the middle part of vehicle frame 2 is provided with self-actuating brake control chamber 3, self-actuating brake control chamber 3 is connected with inflation/deflation switch 10.
Described electric wheelchair does not arrange reducing gear.
Described brake 7 is the automatic disc brake of gas control or the lock that rises.
Described self-actuating brake control chamber 3 is provided with air pump, is the pneumatic brake power source, can be simultaneously tire from inflation.
The rear portion of described electric wheelchair is provided with rear pedal 4.Rear pedal has support wheel, the personnel that follow is stood onboard, without walking.
Collapsible the packing up of described rear pedal 4.
The beneficial effects of the utility model:
(1) wheelchair of the present utility model is not installed reducing gear, has improved transmission efficiency, there is no the solenoid of long-time energising, has reduced the consumption of power supply.
(2) adopt aerodynamic brake, very sensitive, reliable, the safety of braking.
(3) inflator pump has the automatic inflating function, fills once gas and can brake 12 times.
(4) rear pedal can carry the entourage, more than total load capacity of wheelchair reaches 160kg.
Description of drawings
Fig. 1 is this utility model electric wheelchair structure schematic diagram;
In figure, before 1-rocking rod controller, 2-vehicle frame, 3-self-actuating brake control chamber, 4-rear pedal, 5-, follow-up steering wheel, 6-brake cylinder, 7-brake, 8-directly drive low-speed DC magneto, 9-lithium battery, 10-inflation/deflation switch.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
A kind of electric wheelchair, the front end of vehicle frame 2 is provided with rocking rod controller 1, the lower end is provided with front follow-up steering wheel 5, directly driving low-speed DC magneto 8 is connected with brake 7, brake 7 is connected with brake cylinder 6, lithium battery 9 with directly drive low-speed DC magneto 8 and be connected, the middle part of vehicle frame 2 is provided with self-actuating brake control chamber 3, self-actuating brake control chamber 3 is connected with inflation/deflation switch 10.Brake 7 is the automatic disc brake of gas control or the lock that rises.Self-actuating brake control chamber 3 is provided with air pump, and air pump is automatic charging air pump.The rear portion of electric wheelchair is provided with rear pedal 4.Rear pedal 4 is collapsible to be packed up.Lithium battery 9 is the DC24V15Ah lithium battery.Directly drive low-speed DC magneto 8 and directly drive the low-speed DC magneto for wheel shell-type brushless gearless.
The operation principle of this electric wheelchair: one or two finger push-and-pull rocking rod controller that swings, can realize by the advancing of electric wheelchair, fall back, turn in the left and right and original place 360 degree revolutions, when decontroling hands, namely realizes the automatic gas brake.automatically control two of left and right during turning and directly drive the low-speed DC magneto, one is fast, one is slow, until one advance, one falls back, air pump and self-actuating brake control chamber are when switching on power, air pump starts approximately 1 minute automatically, air pressure reaches the setting value pump trip, brake is 10-12 time continuously, when air pressure is reduced to setting value, pump is opened automatically, approximately 20 seconds air pressure goes up pump trip, Vehicle Driving Cycle and gas are stopped general power only for 375W, can connect trachea to the tyre inflating of oneself by air valve switch when under-inflation, reduced the possibility of fault stagnation of movement, power cutoff, open air valve switch, can travel by hand push.Owing to there is no reducing gear, improved transmission efficiency, the solenoid that there is no long-time energising, reduced the consumption of power supply, improved moment of torsion under same power, institute is 35km so that this automobile-used small-capacity cells can continue, if identical with original technology wheelchair battery capacity used, can make course continuation mileage improve 1.75-2 doubly.
Electric wheelchair gross weight of the present utility model is the 30kg left and right, load reaches 160kg, battery capacity 15Ah, and more than common electric wheelchair gross weight is generally 45kg, the highest 135kg of load left and right, battery capacity is generally 20～50Ah, and course continuation mileage only can reach 12～30km, and electric wheelchair performance of the present utility model obviously is better than the commercial like product.
