Embodiment Construction

[0039] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0040] see Figure 1 to Figure 15 , this embodiment discloses a reconfigurable wheel, including a support frame, the support frame includes two end covers 1, a fixed base 2, the fixed base 2 is a ring structure, and the two end covers 1 are arranged oppositely and respectively Fixed on both ends of the fixed base 2 , the end caps 1 are triangular in shape, and the three corners of the two end caps 1 are respectively connected together by connecting plates 3 . Three groups of reconstruction units are evenly distributed along the circumference of the supporting frame, and a crawler belt 4 is covered on the periphery...

Abstract

The invention discloses a reconfigurable wheel. The reconfigurable wheel comprises a supporting frame, the supporting frame is evenly provided with three reconfigurable units in the circumferential direction, the periphery of the three reconfigurable units is coated with a caterpillar band, and each reconfigurable unit comprises a first driving mechanism, a connecting block, a power shaft, a powergear and two deforming supporting parts, output shafts are driven to stretch out and draw back through the first driving mechanisms, the connecting blocks are driven to move in the radial direction,on one hand, the power shafts and the power gears are driven to move in the radial direction, through the power gears, the caterpillar band is ejected out or retract, on the other hand, the two sets of deforming supporting parts are driven to take back or open, the deforming caterpillar band is supported, and conversion under two modes of the wheel type and the caterpillar band type can be achieved; and a second driving mechanism is arranged on the supporting frame, through the second driving mechanism, the three power gears are driven to rotate, and the caterpillar band can be driven to run.The reconfigurable wheel has the advantage that rapid back-and-forth switching between two modes of the wheel type and the caterpillar band type can be achieved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a reconfigurable wheel. Background technique [0002] The mobile mechanism of the robot is generally divided into two types: wheel type and crawler type. The wheel type drives on the hard ground and only rolls on the ground, which makes the robot very stable during the driving process. The crawler type expands the contact area with the ground and can run smoothly on soft ground. These two modes of movement all make the movement of the robot have certain limitations. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a reconfigurable wheel, in order to quickly switch back and forth between the wheeled and crawler modes, so that the robot can flexibly cope with various complex road conditions. [0004] The present invention is achieved through the following technical solutions: [0005] A reconfi...
