Description
Technical field
The present invention relates to a kind of power assist vehicle, more particularly to a kind of foldable chassis for power assist vehicle.The present invention also enters one
Step is related to fold product technical field, and in particular to new drawstring quick release fold mechanism.The invention further relates to voluntarily
Car saddle.
Background technology
Usually, power assist vehicle is referred to power source drives such as manpower, electric power or engines, with carrying personnel and/or thing
The quickly mobile vehicles of body.Although many power assist vehicles under certain conditions can be with many people of carrying, existing most of power-assists
Car is only designed to carrying one or appropriate object.Common manpower drives power assist vehicle, such as bicycle, stepping on user
Legpower drives and itself moves as power；Driven by power power assist vehicle, such as electric bicycle, Segway Human Transporter or electric motor car, with
Electric power drives and itself moves as power；Engine driving power assist vehicle, such as motorcycle, with the driving masterpiece that engine is produced
For power, drive and itself move.
Existing many power assist vehicles are not foldable, therefore, it has larger volume and weight and is difficult to be entrained into public friendship
Logical instrument, such as bus and taxi.Which greatly limits the use of power assist vehicle.In order to solve the volume of power assist vehicle
Big and not Portable belt defect, researcher designs the power assist vehicle with folding structure.Foldable power assist vehicle can be rolled over
Fold and after being folded, occupy less space, consequently facilitating the carrying of user, transport and placement.But, existing majority
There are following at least one defects folded moped more：First, cannot realize folding more than existing power assist vehicle fold mechanism simultaneously after,
Volume is little as far as possible；After expansion, it is easy to user to ride and firm support is provided.Or existing power assist vehicle is to fold
There is afterwards smaller size smaller, but after deployment inconvenient user rides and/or is difficult to provide firm supporting construction；After being expansion
It is easy to user to ride and firm support is provided, but still there is larger volume and weight, constant carrying after folding.Secondly, folding
Stack structure is complicated, and folding step loaded down with trivial details and inconvenient user use.Again, in order to realize folding, the overall structure of power assist vehicle sets
Meter is not safe enough.Particularly, in order to power assist vehicle overall structure is realized folding, and cause overall structure unreasonable and cannot be in power-assist
Flexible operation and firm support are provided during car traveling.Further, existing folded moped is after being folded, more with not
Irregular figure, such as forms projection or corner angle, so that it is when being carried or placing, is susceptible to collide with.Such as Application No.
The Chinese utility model patent of CN201310302198.4 teaches a kind of foldable power assist vehicle (electric motor car), and wherein this is foldable
Power assist vehicle has front frame, middle main body, Rear frame and two folding connecting rods.The folded moped of the Chinese patent teaching can pass through
One lift-pull handle wherein main body will be lifted up, so that front frame and Rear frame are natural under gravity leaning on to middle main body
It is near and fold.The foldable power assist vehicle that the patent application is disclosed has many defects：First, user must be by carrying
Draw wherein main body to realize folding, cause in the folding process of the foldable power assist vehicle, to need user from bottom to up
Lift middle main body and overcome whole middle main body, or even the weight of whole power assist vehicle, this brings to the folding of the foldable power assist vehicle
Difficulty.Secondly, the complex structure of the foldable power assist vehicle, even after being folded, remaining on larger volume and weight.
Again, the folding mode of the foldable power assist vehicle is by main body in lifting, so that front frame and Rear frame are to middle main body
Fold.Therefore, even if the foldable power assist vehicle is folded, it still has larger volume and weight.Finally, the folded moped
Pivot point is excessive, and this causes the overall structure of the folding not enough to consolidate.
Bicycle, body-building apparatus etc. can all be related to fold mechanism, can fold up product, be easy to collection management
And transport, especially folding bicycle, general folded bicycle has vehicle frame folding joint and standpipe folding joint to constitute.Rolled over by vehicle frame
Folded, the two-wheeled doubling by before and after together, can reduce by 45% or so length.Car load can be put into after folding boarding case and folding bag
It is interior, and the boot of automobile.Also without by external tools during folding, can manually by car folding and expanding.
After folding by seat bar as the strong point so as to can stand after folding surely.Folding bicycle is carried, easy to use comfortable, production technology
It is ripe.But the complex structure of the fold latch of existing these products, needs first to open safety lock, then strikes out handle with the hand,
Can fold, complex operation, and due to being all made of metal, heavier-weight causes whole product to seem heavy, is not easy to behaviour
Make and transport, it would be highly desirable to improve.
Bicycle saddle is just mounted on bicycle saddle tube, for providing a kind of indispensable important of sitting posture support
Part, it is the decisive part of comfort level of riding.
Take up room when at present bicycle saddle on the market is placed larger, storage and transport carry inconvenient, and at present
Saddle all using there is bow structure.
