Abstract

Provided is a digital inertia dumbbell capable of measuring motion parameters. A circuit board is fixedly arranged inside a shield, a Hall code disc is connected to the circuit board, the Hall code disc is provided with a Hall component, the axial lead of the Hall code disc coincides with the axial lead of an eccentric rotary shaft, a magnet rotary disc which is adjacent with the Hall code disc in parallel is arranged inside the shield, the magnet rotary disc is fixedly arranged at one end of the eccentric rotary shaft and is coaxial with the eccentric rotary shaft, a permanent magnet is arranged on the magnet rotary disc, a micro-processor is arranged on the circuit board and is connected with the Hall component on the Hall code disc, the micro-processor is connected with a display screen and a data storage module, and the display screen is fixedly arranged in the shield. The digital inertia dumbbell capable of measuring the motion parameters can measure the times, time, speed and interrupt times of rotation of the eccentric rotary shaft in the inertia dumbbell in real time, the motion parameters are displayed through the display screen in real time or stored through the data storage module, and accordingly the motion intensity, coordination condition and motion progress can be reflected accurately.

Description

Technical field: [0001] The present invention relates to articles for human life, in particular to a body-building device, in particular to a dumbbell, in particular to a digital inertial dumbbell capable of measuring motion parameters. Background technique: [0002] Dumbbells are commonly used personal fitness equipment, which can assist in the exercise of upper arm and shoulder girdle muscle strength. However, dumbbells do not significantly help the coordination training of nerves and muscles. Therefore, the applicant proposes a dumbbell with adjustable inertial resistance load in Chinese patent CN101664592B, in which a rotatable main shaft is arranged inside the dumbbell handle, pendulum rods are respectively arranged at both ends of the main shaft, and pendulum rods are arranged on the pendulum rod. hammer, forming an eccentric pendulum. When the direction and period of force are appropriate, the eccentric pendulum rotates to generate periodic inertial force, which cau...
