Abstract: This application relates to the technical field of energy storage devices, and in particular, to a box body, a battery pack, and a device. The box body includes a first beam and a second beam. The first beam and the second beam intersect each other, and are connected by a connecting portion, and partition the box body into a plurality of accommodation spaces. The first beam includes a body and a recess. The recess is recessed inward relative to the body. The connecting portion is disposed in the recess. In this way, a joint position between the first beam and the second beam will not protrude from a lateral surface of the first beam, thereby preventing a short circuit of a battery cell caused by puncture of or damage to an insulation film outside the battery cell, and improving safety performance of the battery.

Abstract: The present application provides a power generator, a suspension, a vehicle, an apparatus and a method for producing a power generator. Among them, the power generator comprises a cylinder body, a moving member, and a piezoelectric conversion unit. The moving member and the cylinder body jointly defines a variable cavity. The piezoelectric conversion unit is located in the variable cavity, and the piezoelectric conversion unit is configured to deform when the moving member is in relative motion with respect to the cylinder body move and changes the size of the variable cavity, for generating electric energy. Due to the fact that the piezoelectric conversion unit is arranged in the variable cavity, the moving member is in relative motion with respect to the cylinder body to make the piezoelectric conversion unit generate electric energy, thus effectively utilizing the energy generated by the target members in the vibration process.
