The other end；Wherein, the handrail member, the upper connecting rod, the lower link, the top base, the bottom base form one or four
Link mechanism.It solves the technical issues of traditional handrails are high to space requirement, and use scope is restricted by above device, reaches
It is foldable to handrail, save space, technique effect applied widely.
2nd, the utility model embodiment is by being respectively equipped with upper limit plane on the top base and the bottom base, it is described on
Confined planes limit the maximum folded position of the folded state.Reach the limitation upper connecting rod, the maximum of lower link folded state
Folding position prevents the technique effect of the handrail undue folds.
3rd, the utility model embodiment on the top base and the bottom base by being respectively equipped with lower limit plane, under described
Confined planes limit the maximum open position of the opening state.Reach the limitation upper connecting rod, the maximum of lower link opening state
Open position prevents the technique effect of the handrail Use overrun.
4th, the utility model embodiment is identical cam by first cam mechanism and second cam mechanism
Shape, reaching makes the upper connecting rod synchronous with lower link movement, smooth opening and the technique effect for folding the handrail.
5th, the utility model embodiment is respectively provided with transfer point by first cam mechanism and second cam mechanism,
And under the action of the leaf spring, the excessively described transfer point of the handrail movement, the handrail reaches opening state or the folding
State reaches the technique effect of handrail described in auto-folder.
6th, the utility model embodiment provides a kind of vehicle, and the vehicle further includes a kind of foldable handrail, described to help
Hand further includes：Handrail member, upper connecting rod, one end of the upper connecting rod are hinged described handrail member one end；Lower link, the lower link
One end is hinged the other end of the handrail member；Top base, the top base connect the other end of the upper connecting rod；Bottom base, institute
State the other end that bottom base connects the lower link；Wherein, the handrail member, the upper connecting rod, the lower link, the upper base
Seat, the bottom base form a four-bar mechanism.Solve traditional handrails to space requirement height, use scope by above device
The technical issues of being restricted, it is foldable to reach handrail, saves space, technique effect applied widely.
Although the preferred embodiment of the utility model has been described, those skilled in the art once know substantially
Creative concept can then make these embodiments other change and modification.So appended claims are intended to be construed to wrap
It includes preferred embodiment and falls into all change and modification of the scope of the utility model.
Obviously, those skilled in the art the utility model embodiment can be carried out various modification and variations without departing from
The spirit and scope of the utility model embodiment.In this way, if these modifications and variations of the utility model embodiment belong to this
Within the scope of the requirement of utility model right and its equivalent technologies, then the utility model is also intended to exist comprising these modification and variations
It is interior.
