This invention discloses a biomimetic cheetah spine-pelvis coordinated elastic energy storage and burst mechanism, belonging to the field of high-speed quadruped robot power drive technology. Existing cheetah spine patents mostly focus on single-spine elastic buffering, failing to address the core mechanism of coordinated burst power through "spine bending + pelvic rotation," resulting in insufficient explosive force and low energy conversion efficiency at high speeds. This invention mimics the biological movement patterns of a cheetah's periodic spinal bending and synchronous pelvic rotation during running, designing a dual-elastic energy storage unit between the spine and pelvis. Through tendon linkage, a complete cycle of "energy storage-release-coordinated burst power" is achieved, enabling the robot to accelerate from 0 to 10 m / s in ≤0.3s with an energy recovery efficiency ≥60%, significantly overcoming the performance bottleneck of existing single-spine mechanisms. This mechanism features an original structure and novel layout, and can be widely applied to high-speed reconnaissance robots, racing robots, and obstacle-crossing robots.

This utility model discloses an adjustable backrest cushion, comprising: a base; a main connecting piece, the tail end of which is connected to the base; an upper main piece, located at the upper part of the head end of the main connecting piece; a lower main piece, located at the lower part of the head end of the main connecting piece; and a transmission module, connected to the main connecting piece, the upper main piece, and the lower main piece. When the upper main piece is subjected to pressure and retracts, the transmission module transmits power to move the lower main piece forward; conversely, when the lower main piece is subjected to pressure and retracts, the transmission module transmits power to move the upper main piece forward. This utility model has the following beneficial effects: Self-triggering adjustment: Utilizing the body's own weight to drive the mechanism, it achieves automatic feedback that "the further you lean back, the stronger the lumbar support." Real-time support force balance: Under rigid mechanical reverse linkage conditions, it achieves dynamic tracking and adjustment of the cushion's support position, adapting to the spinal curvature of different individuals.

The utility model relates to the field of spine curvature measurement technique, proposes a kind of spine curvature measuring instrument, including: bottom plate, support frame, fit board, sliding block, transmission mechanism, recording mechanism, moving mechanism and lifting mechanism, support frame is slidably connected at the top of bottom plate, fit board is equipped with two, two fit boards are all fixedly connected at the top of bottom plate, sliding block is slidably connected in support frame, transmission mechanism is set on sliding block, for measuring the curvature of spine, recording mechanism is set on support frame, for recording curvature information, moving mechanism is set on support frame, lifting mechanism is set on bottom plate, for driving support frame to move up and down, by above-mentioned technical scheme, solved the measurement mode in this kind of measurement mode in relevant technology needs medical staff to complete measurement manually, when medical staff is busy, this kind of measurement mode is more time-consuming and laborious, and simultaneously, reduce the work efficiency of medical staff.
