Description

A kind of Foldable electro-tricycle wheelchair

Technical field:

This utility model relates to a kind of electric three-wheel wheelchair, especially a kind of electric three-wheel wheelchair that can fold.

Background technology:

Current electric wheelchair has three-wheel and four-wheel, also has some to fold, but or due to complex structure operation inconvenience, or due to too expensive, use seldom so far.

Utility model content:

This utility model object is for client provides a kind of novel Foldable electro-tricycle wheelchair.It has traffic safety, ride comfort, light cheapness, easy to operate, is convenient to wait collection advantage.

In order to solve problem existing for background technology, this utility model by the following technical solutions: have a center bed, front end dress front fork, battery and controller.Fill translator front-wheel below front fork, above entrucking handle.Handle is equipped with handlebar, brake lever, and containing headlight, display, loudspeaker, electric door lock assembly.4 jacks are respectively welded in both sides, vehicle frame rear portion.Wheelchair divides left and right two sides, and fill footrest below front end, side, middle part two is respectively welded with 4 jacks.Separately doing 4 rectangle frames is that connecting rod 4 angles have screw.With these 4 connecting rods, put on bolt and center bed and wheelchair two side are coupled together.Seat surface is also that a rectangle frame loads onto an a piece of cloth just one-tenth face in addition.Wherein short tubes are saved through being welded on the right side of wheelchair upper two in the right, and can rotate up and down like this, two latches are equipped with on the left side, to be inserted on the left of wheelchair in upper two jacks.Backrest is also a rectangle frame, and the left side is welded with two latches and is inserted in and is welded on the left of wheelchair in two jacks, and the right is welded with a jack, inserts in this hole being contained in spring catch on the right side of wheelchair.In the middle part of center bed, be welded with two position-limiting tubes, be welded with two banking stops below.Footrest is while there are two jacks, and lower two jacks in front end, wheelchair two side are aimed at and put on bolt and fix, and when footrest forwards level to, another side leans against on banking stop.When rectangle connecting rod forwards certain position backward to, limited masthead lives location.At this moment be exactly this utility model deployed condition.Footrest is upwards dug, and seat surface is upwards dug, and backrest forwards leans against left side.Then push away before wheelchair two side direction, be close to center bed and just become folded state.

This utility model center of gravity is low, not easily overturns during turning, front-wheel drive turning to, can in original place 360 degree turn to.So this utility model has traffic safety, light cheapness, easy to operate, energy-conservation, environmental protection, is convenient to collect advantage.Be applicable to old people and pick child, go out shopping, visit.Take up an area 1 square metre when deployed condition, time folding, take up an area 0.4 square metre.It can be parked in parlor enter elevator, be convenient to charging, not be afraid of and steal.Because it has a relative electric motor car with two wheels of seat, take more comfortable.Wherein there is a model with awning, on and off duty also fine.And car takes up an area 5 squares, if promote this product can solve congestion in road and parking difficulty problem in city.
