Abstract:
(EN) Beam sections (4) are formed of plate-shaped members, and the beam sections (4) are vibrated by external vibration, thereby generating power by means of piezoelectric elements (5) provided in the beam sections (4). In addition, while allowing the beam sections (4) to deform greatly by providing a weight section (6), the displacement of the weight section (6) is regulated by a guide section (7), thereby suppressing excessive deformation of the beam sections (4). This can suppress rupturing of the beam sections (4) and thereby enhance the durability.
(FR) La présente invention concerne des sections de poutre (4) formées d'éléments en forme de plaque, et les sections de poutre (4) sont mises en vibration par des vibrations externes, générant ainsi de l'énergie au moyen d'éléments piézoélectriques (5) disposés dans les sections de poutre (4). De plus, tout en permettant aux sections de poutre (4) de se déformer fortement en fournissant une section de poids (6), le déplacement de la section de poids (6) est régulé par une section de guidage (7), supprimant ainsi une déformation excessive des sections de poutre (4). Ceci peut supprimer la rupture des sections de poutre (4) et améliorer ainsi la durabilité.
(JA) 梁部(4)を板状部材によって構成し、外部振動によって梁部(4)が振動させられることで、梁部(4)に設けた圧電素子(5)による発電が行われるようにする。また、錘部(6)を備えることで梁部(4)の変形が大きくなるようにしつつ、ガイド部(7)によって錘部(6)の移動量が規制されるようにすることで、梁部(4)が過度に変形することが抑制されるようにする。これにより、梁部(4)の断裂を抑制でき、耐久性能を向上させることが可能となる。
