This invention discloses a mechanical muscle device for an automotive collision dummy, relating to the field of automotive safety testing technology. It includes an end cap, a ball screw with both positive and negative threads, a screw nut, a shell flap, an active connecting rod, a pin, and a buffer structure unit. The buffer structure unit is mounted on the shell flap, and its lattice energy-absorbing core layer adopts one of the following: a beetle-inspired curved rib lattice structure, a chiral nested hexagonal structure, or a hexagonal FBCC structure. Through the mechanical coordinated drive of the ball screw with both positive and negative threads and the X-type scissor unit, the rotational motion of the servo motor is precisely converted into the radial expansion and axial contraction of the shell flap, accurately simulating the active tension and passive stretching of muscles during a collision. Compared to pneumatic or hydraulic solutions, this all-mechanical structure has the advantages of rapid response, high control precision, and no leakage risk, avoiding the instability of fluid components under high-speed impact, and significantly improving the bio-simulation of the dummy and the reliability of test data.
