Description
Technical field
The invention belongs to field of mechanical technique, is related to a kind of perambulator of climbing stairs.
Background technology
The residential building of many low layers of China is fitted without elevator at present, with aging and the arrival of the baby boom, upstairs
Problem highlights.For the elderly, live in the floor of no elevator, the such as rice when carrying some heavier articles
Deng, it is possible to make the elderly injured；And for the family for having baby, generally outgoing parents' meeting uses perambulator, but due to
Perambulator is unable to up/down steps, and father and mother upstairs should hold in the arms baby and carry doll carriage again, and a people is difficult to complete, and is consumed
It is huge to take muscle power.
In order to solve the above problems, Chinese patent CN 204659847U disclose a kind of auxiliary building climbing creeper truck, including car
Body and drive device, drive device include crawler belt, driving wheel and some load-bearing inducer groups；Driving wheel is by motor driven, active
Wheel by power with crawler belt engagement by being transmitted to crawler belt, load-bearing inducer group support car body and induction and support crawler belt, wherein crawler belt
Induction tooth is provided with, the article putting groove for loading article is additionally provided with car body；Handle is additionally provided with car body, handle is provided with automatically controlled
Switch and adjustable cramp.
Although above-mentioned building creeper truck of climbing can help the elderly to carry Weight upstairs climbing or trip, and can helps the family for having child
Long belongings, doll carriage and baby get over slope upstairs, but still have the following disadvantages：
1st, above-mentioned creeper truck is in ground running, it is also necessary to relies on motor driving, such as artificial to promote, then resistance is relatively very
Greatly, so that above-mentioned creeper truck is not suitable for ground use, practicality is relatively low；
2nd, for above-mentioned creeper truck when climbing building, vehicle can follow the gradient of stair oblique, and baby can be because of car body on car
Inclination is easily dropped, and practicality is equally relatively low.
The content of the invention
The purpose of the present invention is to be directed to above mentioned problem existing for existing technology, it is proposed that a kind of baby of climbing stairs
Car, the technical problems to be solved by the invention are：How the practicality of this perambulator is improved.
The purpose of the present invention can be realized by following technical proposal：
A kind of perambulator of climbing stairs, it is characterised in that the perambulator includes bearing chassis and vehicle frame, the carrying
Chassis includes disk body, and four corners of the disk body, which rotate, is provided with universal wheel, and the lower surface of the disk body is provided with crawler belt dress
Put, the driving source that the crawler attachment can be driven to be lifted along chassis height direction is provided between the crawler attachment and disk body
One；The upper surface of the disk body is additionally provided with connecting seat, and the bearing chassis also includes to remain the connecting seat
Horizontal adjusting means；The upper surface of the vehicle frame is provided with cradle, and the lower surface of the vehicle frame mutually reclines with connecting seat, described
Four corners of vehicle frame rotate and are provided with wheel, and being provided between the wheel and connecting seat can make both relatively-stationary fixed
Position mechanism.
Its operation principle is as follows：This perambulator on level land in use, because four edges of disk body are provided with universal wheel, can
With normal use, and it is relatively low compared to the mode frictional force of crawler belt；When in stair activity, by driving source one crawler belt can be driven to fill
Decline is put, crawler attachment is touched with ground, so as to carry out stair activity, meanwhile, adjusting means may be such that connecting seat all the time
Keep level position, avoid the baby in cradle from being dropped because of inclination, improve the practicality of this perambulator；And in the application
During positioning vehicle frame, mode that selection is connected with connecting seat with wheel so that on the market general doll carriage can directly with
This bearing chassis matches applicable, further improves the practicality of this perambulator；It should be noted that the disk body in this perambulator
Shape and size with connecting seat are identicals, and both fit together.
