Topic, at present, the information that can transport the vear car that household electrical appliance etc. are compared with heavy articles stair climbing is more rare.
Content of the invention
Technical problem to be solved in the utility model is：A kind of pair of electric cylinder supporting leg lifting booster type energy stair climbing is provided
Vear car, the stair climbing power assisting device of this hand truck is symmetrically installed structure using double electric cylinder supporting legs, makes vehicle frame
Stress equalization, operates steadily, and is easy to operator's control.This car adopts the semiautomatic control mode stair climbing of human-computer interaction, double electricity
Dynamic cylinder supporting leg is responsible for lifting car, and operator is responsible for pulling car, and wheel is replaced with electric cylinder supporting leg and carries car, thus realizing
The continuous stair climbing function of car.
The vear car of this kind of double electric cylinder (or claiming electric pushrod) supporting leg lifting booster type energy stair climbings, by following
14 parts composition (referring to Fig. 1), are vehicle frame 1, the base plate 2 perpendicular to vehicle frame plane, left and right side grip 3, left and right sides list respectively
Wheel 4, chargeable storage storehouse (or frame) and accumulator 5, the left and right sides solely installed can swing electric cylinder telescopic outrigger 6,
Left and right sides electric cylinder supporting leg forward swing positive stop 7, control housing unit 8, the cylinder rod contracting of left and right sides electric cylinder supporting leg forward swing spacing place
Return stroke stop and stretch out, with cylinder rod, the cylinder putting spacing place after stroke trigger switch and its positive stop 9, left and right sides electric cylinder supporting leg
Bar stretches out stroke stop and cylinder rod retraction stroke trigger switch and its positive stop 10, is connected the tie-rod of left and right sides electric cylinder supporting leg
Or be frame 11, prevent from colliding with during left and right sides electric cylinder supporting leg forward swing or the stair rib that rubs support roller 12, be easy to sliding on the ground
Electric cylinder cylinder rod end protective jacket 13 and grip switches 14；Control left and right sides therein can swing electric cylinder telescopic outrigger
(6) in motor rotate forward, reversion and the circuit stopping, by manually and automatically controlling two sets of circuit to form, and by selecting switch control
Alternative one works independently；Described grip switches (14) and left and right sides can swing electric cylinder telescopic outrigger (6) direct-connected, can
Constitute manual control unit；Described grip switches (14), control housing unit (8) and left and right sides can swing electric cylinder flexible
Supporting leg (6) connects, and may make up manual electronic control unit；The cylinder rod of described left and right sides electric cylinder supporting leg forward swing spacing place is retracted
Stroke stop and cylinder rod put the cylinder of spacing place after stretching out stroke trigger switch and its positive stop (9) and left and right sides electric cylinder supporting leg
