Background technique
Child's bicycle product is to be related to the product of children's safety, and relevant department of China in 2003 has promulgated that " country plays
Have technical specification of security " standard, and it is proposed toy product Compulsory Certification of Products, the life of children is protected most possibly
And health, safeguard the interests of consumer.The concept of toy safety is children under normal use or foreseeable reasonable employment, most
Certain defects because of toy itself are avoided to limits to damage to children, these defects may be from design, manufacturing process
Or manufacture material.Critical component is checked according to related specification, being related to safe perambulator product includes child's bicycle, children
Tricycle, children trolley, baby walker, toy cycle, electric children vehicle and other toy vehicles.These vehicles have main
It is to be pushed away to help by adult, such as stroller.Some is mainly manipulated by children oneself, such as child's bicycle, tricycle etc..
These vehicles more have the functional parts such as stow-away arm rest, feed belt not only with some small components, these components one
There is quality problems or failure in denier, not only will affect the use of vehicle, serious also to make to the personal safety of child
At threat.
Although the safety of child's bicycle has very big submission, existing on the market by the effort of each side
Dual-purpose type perambulator product is substantially using fixed vehicle frame (i.e. vehicle frame geometric angle is immutable), is converted into perambulator by scooter and is led to
Frequently with mode be vehicle frame reserve five-way structure either external five-way structure, to realize the installation of transmission mechanism.Due to cunning
The front fork and the optimal geometric angle of vehicle frame that step version and perambulator version need are different, so such product on the market cannot be fine
Adaptation demand double-duty.
Summary of the invention
A kind of height of being designed to provide of the embodiment of the present invention can be changed dual-purpose perambulator, to solve existing perambulator due to
Using fixed vehicle frame, prevent it from well adapting to asking for perambulator demand double-duty and the handling difference of existing perambulator
Topic.
To achieve the above object, the embodiment of the present invention, which provides a kind of height, can be changed dual-purpose perambulator, and the height can be changed dual-purpose

The other end of part 41 is hinged by the tube wall of bolt and saddle tube 3, and the other end of the second connector 43 is plugged in through-hole, wherein
Damper 4 and rear roller 22, damper fixing seat 27 are respectively positioned on the same side of bicycle back fork 21.Bolt need to be only unclamped when installation, just
Replaceable damper 4, greatly shortens the replacing construction of damper 4, can be to better protection children's by the way that damper 4 is arranged
Vertebra.Damper 4 divides for long damper and short damper, and the main distinction of long damper and short damper is elastic component 42
Length is different.
Dotted line is state when perambulator uses short damper 4 in Fig. 1, at this time the height of bicycle beam 12 and 2 hinge joint of vehicle rear portion
It is lower, it turns to sleeve 23 and is in A point position, the angle reduction of bicycle beam 12 and horizontal plane, then the height by reducing vehicle seat 31, make
The children that perambulator is applicable to 2-3 years old use, and since the angle between Chinese herbaceous peony fork 13 and horizontal plane is smaller, the center of gravity of vehicle is more
It is low, it is handling more preferable.State when solid line is using long damper 4, bicycle beam 12 and the height of 2 hinge joint of vehicle rear portion are higher, turn
It is in B point position, the angle increase of bicycle beam 12 and horizontal plane, then the height by increasing vehicle seat 31 to sleeve 23, makes perambulator can
It is used suitable for 4-6 years old or so children, since the angle between Chinese herbaceous peony fork 13 and horizontal plane becomes larger, is more advantageous to and rides.
The height of the present embodiment can be changed dual-purpose perambulator by using variable-angle vehicle frame, make perambulator i.e. and can be used as scooter to make
With, and can be used as child's bicycle use, it is handling good and highly-safe to have the advantages that.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
