A Self-Generating Suitcase Based on Piezoelectric Materials

Abstract

The invention discloses a self-power-generation suitcase based on a piezoelectric material. The self-power-generation suitcase comprises a suitcase body, suitcase wheels, a draw bar, a piezoelectric power generation assembly, and the like. The piezoelectric power generation assembly is disposed at the bottom of the suitcase body, and comprises a piezoelectric power generation structure, shafts, bearings, bearing supports, a rectifier, a storage battery, wires, and the like. The piezoelectric power generation structure comprises cams, piezoelectric plates and cantilever beams. The cantilever beams are fixed to the suitcase body through aluminum sheets or alloy materials with good elasticity modulus. The piezoelectric plates are fixed to the fixed ends of the cantilever beams. The cams are installed on the shafts. The shafts are connected to the suitcase wheels. When the suitcase wheels rotate, the shafts and the cams installed on the shafts are driven to rotate, and deformation of the cantilever beams is generated by the cams, so that the piezoelectric plates deform and generate electricity, the electricity is processed by the rectifier and then stored in the storage battery, and the electricity can be provided for electronic products badly in need of charging for people in travel. Mechanical energy of drawing the suitcase in travel of people is collected, stored and utilized. The suitcase is characterized by being clean, durable, convenient and rapid, and solves the problem of inconvenient charging during going out.

Description

technical field [0001] The invention relates to the mechanical technical field of new energy devices, in particular to a self-generating suitcase based on piezoelectric materials, which is used to solve the problem of inconvenient charging when people travel. Background technique [0002] With the popularization of high-end electronic equipment such as mobile phones and computers and people's frequent travel, whether the power of electronic equipment is sufficient or not has become a very important thing when traveling. When people go out on business or travel, the battery of the electronic device is out of power, and they do not carry a spare battery, which will bring great inconvenience to people's life. Therefore, making it convenient for people to charge anytime and anywhere has become an urgent problem to be solved. [0003] Piezoelectric materials are crystalline materials that generate a voltage between their two ends when pressure is applied. Piezoelectric power ge...
