But the battery capacity is limited, and aging batteries are prone to cause serious environmental problems
Therefore, capturing kinetic energy from the human body has become a method to replace batteries. However, energy harvesters with non-adjustable oscillation frequencies are very inefficient and can capture very little energy under different loads of the human body. Therefore, finding an oscillation frequency can be A tuned energy harvester is necessary and meaningful

The invention discloses a human body kinetic energy acquisition device with the adjustable oscillation frequency. The human body kinetic energy acquisition device with the adjustable oscillation frequency comprises guide rods, supports, sleeves, racks, a movable support, an electric generator and a pushing rod, wherein the middles of the two guide rods are respectively sleeved with one sleeve, the sleeves are located between the two supports, each rack is arranged on one support, the electric generator is arranged on the movable support, and the pushing rod is arranged at the lower ends of the sleeves; a linear sliding rail is arranged at the lower ends of the guide rods, spring hooks are symmetrically arranged at the two ends of the liner sliding rail respectively, a spring is arranged between the spring hooks, and the middle section of the spring is fixed to the middle of the pushing rod; an upright adjusting screw is arranged in the middle of the liner sliding rail, an adjusting rod which can vertically move relative to the adjusting screw is arranged on the adjusting screw, and each end of the adjusting rod is movably connected with one spring hook through a connecting rod. According to the human body kinetic energy acquisition device with the adjustable oscillation frequency, the frequency of the damped oscillation is changed through the change of the extenuation amount of the spring, so that the frequency of damped oscillation is equal to the external driving frequency. Therefore, the efficiency of conversion to electric energy conversion from kinetic energy generated when people walk is improved.
Description
technical field [0001] The invention relates to a kinetic energy capture device, in particular to a human body kinetic energy capture device with adjustable oscillation frequency. Background technique [0002] With the modernization of national defense and the needs of scientific investigations, soldiers and scientific expedition personnel need to carry a lot of electronic equipment, such as GPS, communication equipment, etc., when working in the field. The energy supply of these equipment mainly comes from batteries. However, the battery capacity is limited, and aging batteries are prone to cause serious environmental problems. Therefore, capturing kinetic energy from the human body has become a method to replace batteries. However, energy harvesters with non-adjustable oscillation frequencies are very inefficient and can capture very little energy under different loads of the human body. Therefore, finding an oscillation frequency can be A tuned energy harvester is necess...
