Abstract

The utility model provides a hand-pushing wheelchair installed with an electric tractor. An electrical tractor is connected with a wheelchair by the combination of fibula and blocking lock into one system through the connector and ears hanging components. The tractor comprises a hand-pushing wheelchair with an electric traction; the wheelchair can reversely open a fibula and a blocking lock which can separate the electric tractor; the electric tractor is arranged on shoring feet of the door shape trailer, which is installed with a motor, a driver and an electric brake. The driver is connected with the wheel rotating shaft which is installed between the two shoring feet, and the other shoring feet are installed with batteries. The advantages of the utility model are as follows: the disabled and the old and weak in virtue of hand pushing wheelchair to walk, at the same time, the tractor increases the electrical function, and can not only reduce the burden on the user and enlarge the moving scope, but also make the users can easily self load and unload the connector, make the electric tractor be connected or separated with the hand-pushing wheelchair, and meet the requirements of the use of different environments.

Description

Can load and unload the push-chairs electrically propelled traction vehicle voluntarily

Technical field

This utility model relates to a kind of electrically propelled traction vehicle that is installed on the push-chairs, and it is a kind ofly to be the energy by accumulator, and electric motor driven, user can load and unload the electrically propelled traction vehicle of push-chairs voluntarily by adapter.

Technical background

At present, China has entered aging society, and push-chairs has entered common people family, because push-chairs is in light weight, collapsible, is convenient to deposit and carry, and has become the residual old weak person's of body walking-replacing tool.But, out of doors or the large-scale activity place, to carry out if there are other people, their physical ability is difficult to bear long distance and pulls walking with hands, has limited their range of activity.Though and, speed good with gasoline engine or electric motor driven combustion-motor-driven wheelchairs mobility fast, can grow distance travel because vehicle body is huge and heavy, only should movable out of doors unsuitable inlet chamber in, also deposit and carry and make troubles to user.

Summary of the invention

In order to overcome the deficiency of unsuitable outdoor long distance activity of push-chairs and combustion-motor-driven wheelchairs inconvenience indoor activity, in order to bring into play the indoor walking of push-chairs simultaneously, the advantage of the outdoor walking of electric wheel-chair vehicle, this utility model provides a kind of push-chairs to install electrically propelled traction vehicle additional; The feasible installation of push-chairs and electrically propelled traction vehicle, dismounting, use electrically propelled traction vehicle on the fashionable dress out of doors, remove electrically propelled traction vehicle indoors when using, structure of the present utility model is: electrically propelled traction vehicle carries out hasp by adapter and hangers member and push-chairs, the kayser group mode connects as one, constitute push-chairs with electrically propelled traction vehicle, and can oppositely draw back hasp, kayser, separate electrically propelled traction vehicle, electrically propelled traction vehicle is on a spike of a ∩ shape vehicle frame, one motor is installed, driver and electromagnetic brake, driver and the rotation shaft of wheel that is installed between two spikes connect, and on another spike accumulator are installed, and are welded with a tapered plug head between two spikes, between two spikes of tapered plug head top controller is installed, the embowment of vehicle frame top constitutes handle, and the handle intermediate sleeve is equipped with switch enclosure;

Adapter is installed on the base plate by a support, and both also are penetrated with a rotating shaft and locating rod for movingly on the base plate, support two is welded with supporting plate, locating hole is arranged on the supporting plate, be connected with connecting plate with bolt, connecting plate can rotate 45 degree around connecting bolt, the connecting plate base is fluted, big kayser is arranged at top, in the rotating shaft of base plate turnover panel is housed in addition, and turnover panel can rotate 210 degree around the shaft, taper borehole jack and little kayser are arranged at turnover panel top, and handle is equipped with in taking of little kayser on the ring;

The hangers member is at a metal rod two, be connected with two block pressur plates, the pressing plate at metal rod and its two closes on the pedal support that is buckled in push-chairs, with hexagon socket head cap screw hangers is fixed on the push-chairs pedal support, connecting plate base groove on the connector holder, hang the sill of hangers, the kilocalorie pintle hook lock on the connector holder connecting plate is gone into the entablature of hangers.

The utility model has the advantages that: the residual old weak person of body is in by the push-chairs instead of walking, increased electric functions, promptly alleviate the user physical load and enlarged its range of activity again, user can load and unload adapter leggiero voluntarily, with electrically propelled traction vehicle and push-chairs in conjunction with or separate, satisfy the instructions for use of indoor outer varying environment.Because easy to loading and unloading, electrically propelled traction vehicle, push-chairs can freely separate, and have decomposed the volume and weight of car load, the residual old weak person of donor brings the convenience of depositing and carrying; Simultaneously, because the volume and weight of electrically propelled traction vehicle is no more than the volume and weight of the collapsible push-chairs of aluminium alloy, and its price is significantly less than the price of motorized wheel chair, so increased its probability of promoting the use of.
