Embodiment Construction
[0026] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0027] As a specific example, such as figure 1 As shown, a frequency-adjustable array piezoelectric cantilever beam energy harvester of the present invention includes a base 11, a fixed base 8, a cover plate 10, a housing 5 and a cantilever beam 9, and the housing 5 is a cover-shaped Housing, the housing 5 is fixedly connected with the base, specifically, the housing 5 is mounted on the base 11 by screws, a housing cavity is formed between the housing and the base, and the fixed base 8 is arranged in the housing cavity and fixedly connected with the base, specifically, the fixed base 8 is installed on the base 11 by screws, the fixed base 8 is an L-shaped base, and the cover plate is fixed on the opposite right-angle side of the L-shaped base, so One end of the cantilever beam is sandwiched between the L-shaped base and the cover plate, and the base...
