Abstract

The invention relates to a multifunctional structure capable of carrying out power storage and realizing a damping effect. The multifunctional structure comprises groove structures, wherein grooves are formed in one side of each groove structure; and the grooves of the two groove structures are opposite to each other. A filler having a damping effect is arranged between the groove structures. Power storage structures are arranged between the top of the filler having the damping effect and the groove structure and between the bottom of the filler having the damping effect and the groove structure. The groove structures are formed by elastic high-molecular materials; and the power storage structures are formed by elastic power storage materials or elastic high-molecular materials and the surface is coated with power storage materials. When the structure is vibrated, the mechanical vibration is converted into the electric energy, thereby realizing power storage and power generation functions. At this time, the multifunctional structure serves as a cell block. During the vibration process, the multifunctional structure serves as an elastic damper; and the damping effect can be realized based on energy absorption during vibration. The cost of materials used by the multifunctional structure can be controlled and the weight is light. The multifunctional structure is suitable for large-scale production and application.

Description

technical field [0001] The invention relates to a multifunctional structure, in particular to a multifunctional structure capable of storing electricity and having a shock absorbing effect. Background technique [0002] With the advent of the mobile Internet era, manufacturers are paying more and more attention to the interactive design of smartphones and tablet computers, in order to satisfy users with a better human-machine experience. However, a large number of Internet online activities and entertainment functions lead to a sharp increase in battery power consumption, especially for smart phone users, it has become a very urgent need to charge the mobile phone anytime and anywhere. Therefore, various chargers and mobile power supplies have become popular in the mobile phone accessories market. However, it is impossible for users to carry accessories with them all day, and these accessories cannot really meet the requirements of users who want to charge anytime and anywhe...
