It is deep into the main body after body 8 and by guide rod extension, the inclined side of two corner blocks 4 towards the same side of shell 1, makes
The sliding slot 5 obtained on two corner blocks is parallel to each other, and two inclined connecting rods are parallel to each other, and run through on shell 1 for support column 7
Two through-holes inner wall on be provided with a hollow and annular rubber bushing, which coats support column 7, on robot body 8
The bottom of shell 1 is provided with two sections of symmetrical arc hollowed out areas, the concyclic heart of two of them segmental arc, two support columns 7
The end on the guide rod on robot arm 10 behind two hollowed out areas with the inside of robot body 8 is passed through respectively
It is fixedly connected, wherein being fixedly connected to the first limit at left and right sides of the support column 7 and positioned at the position in 1 top inner wall face of shell
Position plate, the top of first limit plate and the top of shell 1 contact with each other, and are protruding from 7 cylinder of support column outside shell 1
Second limit plate 21 is set at the upper and close shell 1;
The bottom of the sliding block 3 is fixedly connected with rack gear 11, in the groove of the 1 inner wall front and rear sides of shell and corresponding rack gear 11
It is fixedly connected to rolling bearing 12, is flexibly connected between two rolling bearings 12 by driven spindle 13.The driven spindle

21 position of limit plate in embodiment one is moved in 1 top inner wall of shell in the embodiment, and two
New limit plate is increased in a support column main body 7, by the in the same direction towards setting of corner block, can be greatly reduced in shell
The minimum widith of two gear transmission structures is installed, furthermore the fixation and transmission connection of two limit plates and arm, cooperation rubber
Glue bushing and the centrosymmetric hollowed out area of arc, which to realize using same transmission mechanism, waves, inclined lift, waves, simultaneously
Wave movement so that having before carrying out lifting action, can be safer need multiple degrees of freedom to operate, especially rise
Need to carry out before drop early warning wave movement signal synthetic job.The course of work of the embodiment is as follows:
When only need that robot arm wave operation when, forward direction starts positive and negative motor 16, is driven just by positive and negative motor 16
Reversing shaft 17 rotates, and positive and negative shaft 17 drives drive bevel gear 18 to rotate, and drive bevel gear 18 drives driven wheel of differential 15 to rotate,
Driven wheel of differential 15 drives driven spindle 13 to rotate, and driven spindle 13 is rotated with moving gear 14, thus successively band carry-over bar 11, sliding
Block 3 and left side corner block 4 are moved towards the direction of baffle 20, and the corner block on the right is moved far from 20 direction of baffle, due to triangle
Block 4 and pulley 6 cooperate, to successively support column 7 be driven to move upwards, support column 7 slides in house type hollowed out area, and
And drive and be deep into guide rod in ontology 8 on arm 10, drive the guide rod to move upwards so that arm 10 with this
Run-off the straight is swung at the articulated connection of body 8, until the second limit plate on the support column 7 abuts the bottom surface of ontology 8, is cut at this time
The direction of rotation for changing motor 16 drives the corner block 4 on the left side to move far from the direction of baffle 20, and the corner block on the right is towards baffle
The movement of 20 directions drives the guide rod to move downward, to make so that driving the guide rod being deep into ontology 8 on arm 10
Arm 10 is obtained to swing with run-off the straight at the articulated connection of ontology 8, moves in circles and realizes the swing of arm.
When needing to be implemented the height for promoting service robot and the operation for the early warning movement that needs to wave before lifting, then just
To positive and negative motor 16 is started, positive and negative shaft 17 is driven to rotate by positive and negative motor 16, positive and negative shaft 17 drives drive bevel gear 18 to revolve
Turn, drive bevel gear 18 drives driven wheel of differential 15 to rotate, and driven wheel of differential 15 drives driven spindle 13 to rotate, driven spindle 13
Band moving gear 14 rotates, to successively move with carry-over bar 11, sliding block 3 and left side corner block 4 towards the direction of baffle 20, the right
Corner block moved far from 20 direction of baffle, since corner block 4 and pulley 6 cooperate, to successively drive support column 7 upward
Movement, support column 7 slides in arc hollowed out area, and drives the guide rod being deep into ontology 8 on arm 10, and driving should
Guide rod moves upwards, so that arm 10 is with run-off the straight at the articulated connection of ontology 8 to swing, until the support column 7
On the second limit plate abut ontology 8 bottom surface, then motor works on so that the second limit plate on support column 7 pushes away
The bottom surface of mobile robot main body 8, as motor continues to rotate, to push robot theme 8 integrally to move upwards, until machine
After human agent 8 rises to suitable height, positive and negative motor 16 is closed, similarly, when the height for needing to reduce service robot
When, only need the positive and negative motor 16 of reverse starting.
In above-mentioned two operation process, two corner blocks 4 move in the same direction, will not occur such as two in first embodiment
A corner block deviates from the movement of baffle 20 simultaneously, when moving out at the same time so as to avoid the rack gear 11 of two corner blocks of carrying
The minimum for needing to occupy longer width, therefore reducing shell 1 needs to install and design width, saves material and space.
When need to robot carry out Integral swinging when, then can with the positive and negative motor 17 under two corner blocks 4 of independent control,
It keeps revolving speed identical first, when the second limit plate 21 on two support columns 7 abuts to the bottom surface of ontology 8 simultaneously, is switched to
The revolving speed of two motors is different, so that the rate of climb of the support column 7 of a side is faster than another party, so that ontology direction rises
Slower 7 side of support column inclination, the rubber annular bushing that two support columns 7 coat in the through-hole in shell 1 make straight
The vertical state that support column 7 is kept when line lift work, occurs elastically-deformable expansive force then when needing to tilt operation to protect
That demonstrate,proves support column 7 stablizes inclination without unstable irregular collision occurs in the through-hole in shell 1 again.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
