Embodiment Construction

[0017] image 3 It is one of the double helix driving devices implemented in the present invention. The device in the figure is composed of two sets of screw drive systems (1), a stage and support system (2) and a control device (3). Two sets of screw drive systems (1) adopt left-handed spirals and right-handed spirals to form a pair of double spiral mechanisms. When the left-handed screw and the right-handed screw rotate in the opposite direction, the double screw mechanism moves in the left and right directions parallel to the screw axis. When the left-hand screw and the right-hand screw rotate in the same direction, the mechanism advances and retreats in the forward and backward directions perpendicular to the screw axis. When the differential speed between the left-handed screw and the right-handed screw rotates in the same or reverse direction, the mechanism turns or moves along the set direction.

[0018] To implement the above various exercises, the following steps can b...

Abstract

The invention relates to a new type of motion driving mechanism. The walking body adopts a helical mechanism. When the helical mechanism contacts the ground surface, a strong friction pair is formed by the helical contact line or the helical contact surface. Movement or combined horizontal and vertical arbitrary given movement, so as to achieve the purpose of walking movement, this driving form is different from the traditional walking movement, has a strong driving ability, can climb over various obstacles, climb stairs smoothly, and is not affected by various Road restrictions, can adapt to the off-road driving of complex terrain and landforms in the field, can be applied to rescue and disaster relief with complex road conditions or unknown road surfaces, earthquake rescue, obstacle-breaking tools, vehicles for people or materials to climb stairs, etc. The principle of the new spiral walking motion mechanism is simple, It has high reliability, low cost, wide application fields, can be realized in a variety of ways, and can be combined with multiple functions and multiple operation mode applications.

Description

Technical field [0001] The invention relates to a new type of motion drive mechanism that uses a screw mechanism as a walking body. This driving form has strong driving ability, can climb various obstacles, climb stairs steadily, is not restricted by various roads, and can adapt to the off-road driving of complex terrain and landforms in the field. It can be applied to rescue and disaster relief, earthquake rescue, obstacle-crossing tools, and vehicles for people or materials climbing stairs with complicated road conditions or unclear roads. Background technique [0002] With the development and progress of social civilization, people have a variety of needs for walking mechanisms and mobile transportation mechanisms, which has prompted the continuous innovation of walking motion mechanisms, but they also face many challenges. [0003] For dragging and transporting items, animal pulls are a relatively primitive type of walking drive mechanism, which can be adapted to applications ...
