Abstract

The invention discloses a hexagonal rolling mechanism. The hexagonal rolling mechanism consists of a middle transmission assembly A, a left side connecting assembly B and a right side transmission assembly C, wherein the middle transmission assembly A is movably connected with the left side connecting assembly B and the right side transmission assembly C through counter weight shafts. The B1 end of the left side connecting assembly B is connected to the A1 end of the middle transmission assembly A, and the B2 end of the left side connecting assembly B is connected to the A2 end of the middle transmission assembly A. The C1 end of the right side transmission assembly C is connected to the A1 end of the middle transmission assembly A, and the C2 end of the right side transmission assembly C is connected to the A2 end of the middle transmission assembly A. The hexagonal rolling mechanism is provided with a motor (8) for unidirection to perform driving control, changes mechanism shape through motor rotation, accordingly changes the centre-of-gravity position, performs rolling movement under the inertia force effect and has strong balance stability.

Description

technical field [0001] The invention relates to a single-degree-of-freedom moving mechanism, in particular to a hexagonal rolling mechanism. The device can be used for soft ground patrol, long-term monitoring and making teaching aids and toys in the military field. Background technique [0002] Among the plane linkages, the simplest structure and the most widely used is the plane four-bar mechanism composed of four structures. The traditional four-bar mechanism consists of two link frames, a link and a frame. Here, the frame is fixed to the ground. In this way, under the rotation of the motor, the output of rotation or partial rotation is realized. Chinese patent application CN2789106Y discloses a single-power rolling four-bar mechanism. The mechanism consists of four rods and is driven by a motor to separate the frame from the ground. The rack is relatively stationary with the ground in one motion cycle, and in the process of transitioning to the next cycle, the rack and ...
