Abstract

The invention relates to a variable diameter wheel, which comprises a rack. The middle part of the rack is provided with a sun wheel, and the circumambient side of the sun wheel is engaged with a plurality of planetary wheels. Each planetary wheel is successively provided with a correspondent screw slide mechanism, a scissors mechanism and a wheel panel. The screw slide mechanism comprises a screwrod, a guiding rod and a slide table sleeved on the screw slide mechanism and the guiding rod. The planetary wheels drive the screw rod to rotate, the rotation of the screw rod leads the slide tableto move along the axis of the screw rod in a reciprocating motion. The slide table moves along the axis of the screw rod to drive the scissors mechanism to open and close, and the wheel panel moves reciprocally along with the opening and closing of the scissors mechanism. The invention also relates to a diameter-changing method for variable diameter wheels. The structural design of the variable diameter wheel is simple and reliable, which realizes the change of the diameter of the wheel, and greatly improves the ability of the vehicle or the mobile robot to cross barriers, and has a broad application prospect.

Description

technical field [0001] The invention relates to a diameter-variable wheel and a diameter-variable method thereof. Background technique [0002] Existing wheels are generally fixed-diameter wheels. For special occasions, such as post-disaster rescue, deep space exploration, mobile robots, special vehicles and other fields, fixed-diameter wheels have certain limitations. The existing wheel structure design whose diameter can be changed is unreasonable and difficult to use. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a diameter-variable wheel and a diameter-variable method thereof, which are not only reasonable in structural design, but also efficient and convenient. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a variable-diameter wheel, including a frame, a sun gear is arranged in the middle ...
