Description
Technical field
The present invention relates to walking-replacing tool field, more specifically, being related to a kind of based on rotary crank rotation adjusting vehicle body length
The sleigh of degree.
Background technology
A kind of sleigh vehicles indispensable as people's trip, are widely used general, sleigh in daily life
Species it is also very various, sleigh can replace the walking of people, the not only convenient and practical efficiency for also improving walking.But mostly
Existing sleigh can only realize single function of riding instead of walk, and as people's living standard constantly improves, people more focus on more
Sample playing method, the sleigh of simple function can not meet people's needs.
Existing sleigh is typically all that can only be travelled using a kind of state, existing Publication No. CN204659913U
Patent disclose a kind of from scooter, including fuselage, be arranged at two wheels of both sides below the fuselage, be respectively arranged at
Two pedals of two lateral wheels and the direction control lever being connected with the fuselage；Control system is equipped in fuselage,
The wheel and the direction control lever are connected respectively with the control system, pedal and described from passing through hinge between scooter
Connection, non-driving condition pedal can vertically be bonded homonymy fuselage and pack up, and reduce the size of entire car body, two wheels are can differential
Coaxial parallel wheel, not only facilitated to turn to from scooter and meet the groundwork form of tire again, and extended tyre life, it is ensured that travel
Safety；Direction control lever be telescopic rod or collapsible rod, not only be suitble to different heights crowd, but also can under non-driving state incite somebody to action
Direction control lever is folded in certain size；Global design is reasonable, small, easy to operate, passability and good portability, uses
Body-sensing of getting up is comfortable, meets the demand of traveling for a long time.
The patent is in order to allow sleigh to be suitble to the use of more crowds, and there is provided telescopic rod, but this is not enough.
The content of the invention
The technical problems to be solved by the invention be to provide that a kind of user that can adapt to different building shape uses based on rotation
Turn the sleigh that crank rotation adjusts length of wagon.
The purpose of the present invention is what is be achieved through the following technical solutions：
In addition, the present invention also provides it is a kind of based on rotary crank rotate adjust length of wagon sleigh, including：
Front vehicle body and aftercarriage；
The front vehicle body and aftercarriage are by connecting axis connection；
Be provided on the aftercarriage with the connecting shaft coordinate, for control the aftercarriage to close to or away from before
The rotation control telescoping mechanism of the direction movement of car body；
The rotation control telescoping mechanism includes the rotary crank for being associated with the connecting shaft, for adjusting the connecting shaft
Positioned at front vehicle body and the length of aftercarriage front side edge.
Further, the aftercarriage front side edge is provided with the first connection wall, and through hole is provided in first connection wall；
The connecting shaft is connected by through hole with the rotary crank；
During the rotary crank rotation, the connecting shaft stress is moved to the direction close to or away from front vehicle body, so as to
Adjust the length that the connecting shaft is located at front vehicle body and aftercarriage front side edge.In the present embodiment, the front side of the aftercarriage
While being provided with connection wall, which is used to carry the mating connection of the connecting shaft and rotary crank, when the selection crank rotates,
The connecting shaft moves under support and the /V guiding of the through hole of connection wall to the direction close to or away from front vehicle body, so as to
Adjust the length that the connecting shaft is located at front vehicle body and aftercarriage front side edge.
Further, the aftercarriage includes left body, right body and the setting being arranged between left body and right body
Space；
First connection wall is arranged on the front side edge of installation space, and the back side edge of the installation space is provided with the second company
Connect wall；
The rotary crank is rotatably rotatablely connected with left body and the opposite side of right body respectively.This embodiment party
In case, which includes the left body and right body that are oppositely arranged, and the two passes through the first connection wall and the second connection wall respectively
Connection, the through hole are just arranged in the first connection wall of aftercarriage front side edge, and first connection wall is i.e. for left body and right vehicle
The connection function of body, and acted on for the carrying of connecting shaft, and /V and the work being oriented to can be played to the movement of connecting shaft
With achieving many things at one stroke.
Further, the rotation control telescoping mechanism further includes connecting rod, and the rotary crank is connected to institute by connecting rod
State connecting shaft.In the present embodiment, which is connected with rotary crank by connecting rod, in this way, when selection crank and connecting shaft
When rotated, the relative altitude of the two, relative distance can be well connected when changes by connecting rod, without carrying on a shoulder pole
The appearance of the problems such as heart card key.
Further, the connecting shaft is hollow shaft close to the end of aftercarriage, and the connecting rod can be turned by fixed pin
It is dynamic to be connected to the hollow shaft；
The rotary crank includes the first handle coordinated respectively with left body and right body and the second handle and with described the
The 3rd parallel handle of one handle, the dislocation of the second handle；
The connecting rod is socketed on the 3rd handle close to the end of rotary crank.In the present embodiment, the selection crank it
Institute so as to play control connecting shaft between front vehicle body and aftercarriage apart from the reason for be that the selection crank is in rotary course
In, for the 3rd handle when rotating to different angles, the distance apart from front vehicle body is to change, in this way, passing through the connecting rod
Drive, and can drive the connection axially adjacent to or away from front vehicle body direction move, so as to be controlled the connection axle position
Spacing between front vehicle body and aftercarriage, to adapt to the build of different user and demand.
Further, the front vehicle body includes preceding single wheel, and the preceding single wheel is driven wheel or driving wheel；
The wheel cap of the front vehicle wheel is each extended over to both sides is provided with the first front pedal and the second front pedal.In the present solution,
Driver can be needed according to different using in the first front pedal, the second front pedal, the first back pedal and the second back pedal
It is any one or two help driver behavior；Pedal can be provided with sensor, by sensing the pressure of driver, and
Help through the operations such as acceleration and deceleration and steering.
Further, first front pedal and the second front pedal can upwardly or downwardly be turned down along the root of plate.Pedal
It may be reversed, easy to carry or storage.
Further, support base is provided in the front vehicle body, the support base is equipped with handrail upwards；Institute
It states support base and is tiltedly installed with seat support bar to aftercarriage direction, the end of the seat support bar is provided with seat.This
In embodiment, which can help the control that driver is balanced, and can also set sensor or erection speed by interior
Spending control structure etc. helps driver to complete driver behavior, and the seat can be sat down when driver needs, and saves body
