Embodiment Construction

[0028] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0029] The present invention is a heavy-duty light-weight elastic mechanical foot device, such as figure 1 , figure 2 , image 3 As shown, it includes connecting part 1, joint part 2 and sole part 3;

[0030] Connecting parts 1 such as Figure 4 As shown, the connecting part 1 is a whole machined part, and the machined material is aluminum alloy. There is a cylindrical slot on the top of the machined part. The slot is mainly connected with the simple cylindrical robot leg. There are two bolts on both sides of the slot for positioning. Holes for fixed connections. The lower part of the workpiece is a large disc, and a rib is added between the disc and the cylindrical slot in the upper part to increase the strength. Four bolt holes are arranged symmetrically on the large disk, and the bolt holes are for fixing the position of the elastic sponge 20...

Abstract

The invention discloses a heavy-load light elastic mechanical foot which comprises a connecting component, a joint component and a sole component. The connecting component is mainly used for connecting the mechanical foot with a leg. The joint component is provided with four symmetric springs, equivalent motion is a hooke joint, and two-degree-of-freedom motion can be realized, so that the mechanical foot more effectively adapts to complicated terrains. A buffer part is made of isoprene rubber materials in a buffer portion, shock-resistant buffer functions can be achieved under large impact, the sole component is made of polyurethane rubber materials and has a certain anti-slip function, a foot contact portion is provided with projecting particles, and sole adhesion force is increased.

Description

technical field [0001] The invention belongs to the field of mechanical design and relates to a heavy-duty light-weight elastic mechanical foot. Background technique [0002] Traditional legged robots contact the ground through different mechanical feet. Common mechanical feet are generally spherical feet or simple flat or curved feet, and auxiliary springs and other shock absorbing devices are added. The structure and function of this type of mechanical foot are relatively simple, and most of them are only suitable for walking on rigid and flat ground, but the walking effect on complex road surfaces is poor, and they cannot adapt to the terrain well. At present, there are few mechanical feet specially designed for heavy loads at home and abroad, and most of the mechanical feet are traditional mechanical feet. At present, mechanical feet with elastic properties that can realize heavy loads and complex ground walking generally have a large weight, which causes many problems...
