Description
Technical field：
The present invention relates to a kind of electric wheelchair of facilitating going upstairs and going downstairs, it is related to electric wheelchair technical field.
Background technology：
Electric wheelchair is superposition high-performance power drive unit, smart steering device, battery on the basis of traditional manual wheelchair
Deng part, what transformation and upgrade formed.Possess artificial manipulation intelligent controller, advance with regard to wheelchair can be driven to complete, retreat, turning to,
Stand, lie low, etc. multiple functions New Generation of Intelligent wheelchair, be the fields such as modern precision machinery, intelligent numerical control, engineering mechanics
The high-new technology productses being combined, and electric wheelchairs many at present stair activity in actual use is inconvenient, thus it is practical
Property is not high.
The content of the invention：
The technical problems to be solved by the invention are：There is provided it is a kind of simple in construction, it is easy to use and can effectively realize stair activity
Electric wheelchair.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of electric wheelchair of facilitating going upstairs and going downstairs, including wheelchair pedestal, front wheel and rear roller and bottom townhouse are taken turns more
Body structure, the front wheel and rear roller are respectively placed in the front and rear part of wheelchair pedestal, the more Wheel structure bags of bottom townhouse
The multiple action rollers being mutually juxtaposed and roller bearing fixed mount are included, the roller shaft movable supporting of multiple action rollers is fixed on roller bearing
On fixed mount, the upper end of the roller bearing fixed mount is fixedly connected on wheelchair pedestal bottom, the bottom by retractable supports axle
The more Wheel structures of townhouse are arranged to two groups and are placed in the bottom both sides of wheelchair pedestal.
Preferably, the wheel body upper ring cap of multiple action rollers has crawler belt.
Preferably, the retractable supports axle is arranged to the telescoping mechanism controlled by hydraulic cylinder.
Preferably, the quantity of the retractable support axle is arranged to multiple and arranged in parallel.
Preferably, the lower end of the retractable supports axle and the junction of roller bearing fixed mount are provided with an elastic telescopic
Mechanism.
It is connected to preferably, the elastic telescopic mechanism includes flexible guide rod and compression spring, the flexible guide rod
Between the lower end of retractable supports axle and roller bearing fixed mount, the compression spring is socketed in outside flexible guide rod.
Compared with prior art, usefulness of the present invention is：The overall structure is simple, and installation makes and operation side
Just, electric wheelchair up/down stair can be effectively realized, and stair activity process stability is high, thus there is higher practicality, fit
Close popularization and application.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is the side structure schematic diagram of the present invention.
Embodiment：
