Central gear 6 is with merging empty set on the bracket 7;The other end of first transmission shaft 4 of three planetary gear mechanism 15 with
The cooperation of second driving motor 16;5 one end of second driving shaft of three planetary gear mechanism 15 is fixedly connected with the bracket 7;Separately
One end and the belt wheel 14, which are realized, to be cooperated, and the belt wheel 14 is connect by belt 13 with the first driving motor 12;The detection is sentenced
Disconnected module is arranged in the chassis body 11, and for judging whether robot is in stair climbing state, if should turn.
In some embodiments, the detection judgment module includes ultrasonic wave module and gyroscope 18;Robot chassis is logical
Gyroscope 18 and ultrasonic wave module crossed as auxiliary judgment module realize the autonomous climbing on robot chassis.Robot chassis row
When sailing, the gyroscope 18 is for judging whether robot is in stair climbing state;The ultrasonic wave module is for judging machine
Whether people should turn, to realize that robot chassis is independently gone upstairs.
Specifically, when robot chassis is in horizontal plane (not going upstairs), gyroscope 18 judges current robot chassis
Angle information (being assumed to be 0 °) and keep in for compare below, can be generated when robot chassis starts to go upstairs bright
Aobvious angular deviation (being assumed to be 45 °), can be denoted as robot chassis at this time and start to go upstairs.With should be on robot chassis
When to plane location between stair, robot chassis angle can become horizontal plane angle (0 °) again again, bright with (45 °) before generations
Aobvious differential seat angle (45 ° of difference), being denoted as robot chassis arrived plane location between two sections of stair.
In one embodiment of the present of invention, respectively dispose four high-precision ultrasonic wave modules before robot (2),
Left and right end.When robot chassis is climbed to stair, system starts ultrasound examination, arrives (stair) plane on robot chassis
Afterwards, the speed of travel is reduced, and judge robot chassis and left and right abutment wall wall and front wall by 3 ultrasonic waves simultaneously
Distance realizes that robot chassis is independently turned;During the turn, whether the data for judging that the ultrasound of front two arrives are big
Cause it is identical, if data difference very little, then it is assumed that robot chassis does not need to turn again, and otherwise robot chassis continues to turn,
Until data difference is sufficiently small.Robot chassis has arrived at the bottom of stair after completing two turnings, closes ultrasound at this time
Speeling stairway is continued on wave detection, robot chassis.
In some embodiments, first driving motor 12 and the second driving motor 16 are all DC brushless motor.
In some embodiments, the chassis body is integrally in rectangle, and three planetary gear mechanism 15 is 4, and respectively
It is distributed in 4 ends of the chassis body 11.
The present invention also provides a kind of robots.The robot includes foregoing robot chassis.
Due to vehicle frame, transition gear, driving gear (including wheel) is all empty set on corresponding axis, therefore drive train
Comprising three completely identical in structure differential gear trains, these three differential gear train common center wheels and vehicle frame, and it is circumferentially symmetrical
Distribution, adds transition gear, it is ensured that while two wheels to land have rotation direction identical with central gear, towards same side
Advance to rolling.Robot mainly realizes the autonomous of robot as auxiliary judgment module by gyroscope and ultrasonic wave module
Climbing.
Three planetary gear mechanisms stable structure provided by the invention, high reliablity;Robot chassis is arranged using each star-wheel
Two motors, so that the ability of bearing a heavy burden on robot chassis increases, movement is flexible, the design of belt pulley is so that robot chassis can
Continuously to move, it is not easy to cause bobbin movement discontinuous because choosing needle;Three planetary gear mechanism provided by the invention, robot bottom
Disk and robot can be very good to realize the difficulty that stair are crossed by robot, movement energy of the hoisting machine people under complicated landform
Power.
