Equipment for assisting sweeping robot in sweeping stairs

Abstract: The invention relates to equipment for assisting a sweeping robot in sweeping stairs. The equipment comprises a rail mechanism, a box body, a manipulator lifting mechanism and a manipulator grabbing mechanism, the rail mechanism comprises a nesting device; the nesting device is mounted on a handrail of the staircase and is provided with a nesting driving motor; the nesting device is driven by thenesting driving motor to move in the length direction of a handrail of the stair. The box body is fixedly connected to the lower part of the nesting device; the manipulator lifting mechanism is mounted in the box body and comprises a lifting motor; the power output end of the lifting motor is connected with a lifting hoisting mechanism through a lifting transmission mechanism; the manipulator grabbing mechanism is mounted at the lower part of the lifting hoisting mechanism; the lifting motor drives the mechanical arm grabbing mechanism to ascend and descend by driving the lifting hoisting mechanism to act. The stair climbing function of the sweeping robot can be achieved, and the sweeping robot can move leftwards and rightwards to sweep stairs in the stair climbing process.

Stair-climbing luggage case and stair-climbing assisting device

Abstract: The invention discloses a stair-climbing luggage case and a stair-climbing assisting device. The stair-climbing luggage case includes a luggage case body and also includes the stair-climbing assisting device for assisting a user to carry the luggage case in a stair road section; the stair-climbing assisting device includes glide wheels and tracks; the sliding wheels are mounted on the tracks and can freely slide along the tracks. With utilization of the glide wheels rolling on a stair hand railing, the time and the labor are saved, and the luggage case is more convenient for people to use when the luggage case is used.

Stair-climbing hand truck

Abstract: The stair-climbing hand truck is an improved hand truck that includes a back plate with a plurality of secondary wheels that may be used to roll the hand truck along a floor surface or up or down a flight of stairs. The back plate is rigidly affixed to the vertical frame of the hand truck. Moreover, the back plate is acutely oriented behind the vertical frame. The back plate has at least one wheel on opposing sides, which adaptively interact with a ground surface to roll the entire assembly. The vertical frame and the back plate are supported with primary wheels that are located adjacent to where the vertical frame meets a load plate. The primary wheels have a diameter larger than the wheels of the back plate.

Floor sweeping robot with stair climbing function, connecting structure and electromagnets

Abstract: The invention, which belongs to the technical field of smart home equipment, especially relates to a floor sweeping robot with the stair climbing function, a connecting structure and electromagnets. The main body structure of the floor sweeping robot is different from that of the existing sweeping robot; the robot comprises a main body, supporting arms and supporting feet. Two ends of the supporting arms are respectively hinged with the main body and one end of each supporting feet to form a folded chain-like structure; each joint of the chain-like structure is provided with an independently controlled driving structure and thus the joints can move, so that the robot can climb stairs to reach the upper floor indoors for cleaning. Connecting shafts are arranged on the two sides of the mainbody, electromagnets are arranged in the connecting shafts, the electromagnets and the supporting arms can form temporary shafts to be used for stair climbing by electrifying the electromagnets, and the electromagnets can be separated from the supporting arms and the supporting feet when climbing is not needed.

Spinal Curvature Kinematics of Stair Ascending for the Second and the Third Trimesters of Simulated Pregnancy in a Month by Month Basis.

Abstract: Pregnant women may adopt some postural adjustments, especially in the lumbar and thoracic regions of the spinal column, in order to cope with the weight gained during pregnancy to improve the stability. Stair climbing is one of the daily activity pregnant women performs almost everywhere they present. The objective of the current study is to investigate stair ascending spinal curvature kinematics in simulated pregnancy during the second and the third trimesters in a month by month basis. Compared to nonpregnant, simulated pregnancy in the 9th month show significantly greater thoracic angle (P=0.005). The 7th,8th, and 9th month of simulated pregnancy shows greater lumbar angles with P values of 0.033, 0.01, and 0.046, respectively, compared to non-pregnant. The increase of lumbar extension Angle maybe adopted in order to relocate the position of the center of gravity posteriorly in response to the anteriorly added mass to improve stability.
