Further, when first universal wheel abuts ground, first universal wheel and first wheel, second
Wheel is laid in equilateral triangle.
Further, the wheel jack also includes the second universal wheel, and the slider-crank mechanism also includes described
Second crank and the second connecting rod being rotationally connected between second crank and the sliding block, second crank, which is rotated, to be connected
The car body is connected to, and is fixedly connected on second universal wheel：When the telescoping mechanism drives the sliding block to be moved to first
During position, second universal wheel abuts ground to carry the car body, when the telescoping mechanism drives the sliding block to be moved to
During the second place, second universal wheel is contained in the vehicle body.
Further, when first universal wheel, the second universal wheel abut ground, first universal wheel, second
Universal wheel is respectively positioned on first wheel and divided equally with the second the vertical of wheel line on face.
Further, the telescoping mechanism includes motor, sleeve, trapezoidal screw, screw:The trapezoidal screw, screw position
In the sleeve inner；The motor connection is between the car body and the trapezoidal screw, for driving the trapezoidal screw
Reciprocating rotation；The screw is threadedly connected to the trapezoidal screw, for driving the sliding block to move back and forth；The sleeve and institute
State and guiding mechanism, the rotation for limiting the screw are provided between screw.
Further, the telescoping mechanism also includes connector, rolling bearing：The connector is fixedly connected on the silk
It is female between the sliding block；The rolling bearing is assemblied between the sleeve and the trapezoidal screw, and the neighbouring motor.
The car body is formed with the first limited block, the second limited block, when first universal wheel, the second universal wheel abut ground
During face, first crank, the second crank bear against first limited block, the second limited block.
Further, first crank, the second crank structure are identical, and the first universal wheel, the second Universal wheel structure are identical.
Compared with prior art, advantages of the present invention and beneficial effect are：The self-balance robot that the present invention is provided, without
Self-balancing just can be realized by complicated software algorithm.The wheel jack set up, when sliding block is moved into first position,
First universal wheel abuts ground, the first universal wheel now effective strong point that caused self-balance robot many, not only can be with
Together play a part of bearing body with the first wheel, the second wheel, so that the bearing capacity of balanced robot is effectively improved, and
Due to the first universal wheel have in itself can 360 degree rotations characteristic, when self-balance robot is in mobile, do not interfere with certainly yet
The operation of balanced robot, and the first universal wheel set up also effectively prevent operating self-balance robot and needs to adjust at any time
It is whole to ensure to maintain dynamically balanced state, the problem of it also avoid the low bearing capacity that dynamic balancing is brought.

Pneumatic slid platform etc., motor 51, sleeve 52, trapezoidal screw 53, silk are specifically included to simplify telescoping mechanism 50 in structure, the present embodiment
Mother 54.Wherein, trapezoidal screw 53 is threadedly coupled and is respectively positioned on inside sleeve 52 with screw 54, and is set between sleeve 52 and screw 54
There is guiding mechanism（Accompanying drawing is not shown）, the rotation for limiting screw 54, for example, guide frame can be formed at the screw
Guide pad on 54 and the guide groove being formed on the inwall of sleeve 52, guide pad, which is plugged in guide groove, realizes limitation silk
The rotation of mother 54.Motor 51 is connected between car body 20 and trapezoidal screw 53, and the reciprocating rotation of trapezoidal screw 53 is driven to realize, by
In screw 54 be threadedly coupled with trapezoidal screw and sleeve 52 and screw 54 between the guiding mechanism that sets, trapezoidal screw 53 it is past
Multiple rotate can realize moving back and forth for screw 54, therefore, and screw 54 can move back and forth for drive sliding block 42.In the present invention
Screw 54 can be both made into integration with sliding block 42 using same material, can also be welded to connect, because screw 54 is located in sleeve 52
Portion, for the ease of dismounting, that is, facilitates the connection or dismounting between screw 54 and sliding block 42, specifically, telescopic machine in the present embodiment
Structure 50 also includes connector 55, rolling bearing 56, wherein, connector 55 is fixedly connected between screw 54 and sliding block 42, can
Realize being fixedly connected between screw 54 and sliding block 42, moreover it is possible to play a part of guiding to the movement of sliding block, connector 55 it is upper
Portion is located inside sleeve 52, and its underpart is located at the outside of sleeve 52 and is fixedly connected with sliding block 42, for example, can be connected using screw or bolt
Connecting connector 55 and screw 54, and will be welded to connect by the way of welding between sliding block 42 and connector 55, as shown in figure 4,
Rolling bearing 56 is then assemblied between sleeve 52 and trapezoidal screw 53, and neighbouring motor 51, in order to reduce sleeve 52 with it is trapezoidal
Abrasion between leading screw 53, moreover it is possible to prevent dust, particle etc. from entering sleeve 52.
In addition, on the basis of the present embodiment, can be formed with car body 20 again in other embodiments of the invention
One limited block, the second limited block, can be realized by welding or bolt connection or be integrally formed so that first universal wheel 31,
When second universal wheel 32 abuts ground, i.e., when sliding block 42 is moved to first position, the first crank 41 is against the first limited block and the
Two cranks 44 can improve the steadiness of wheel jack against the second limited block, the first limited block, the setting of the second limited block,
Improve its usage cycles.On the other hand, in order to simplify the buying types of parts, the versatility of parts is improved, can also be designed
First crank 41, the structure of the second crank 44 are identical, and the first universal wheel 31, the structure of the second universal wheel 32 are identical.
Although the aspect of the present invention is subject to specifically shown and explanation, those skilled in the art with reference to above-described embodiment
It will be understood that, can be by being modified to disclosed technical scheme come pre- on the premise of disclosed spirit and scope are not departed from
Phase various other embodiment.Such embodiment is appreciated that true such as based on claims and its any equivalent
In fixed protection scope of the present invention.
