The invention discloses a multifunctional structure with the heat absorption cooling effect and the vibration reduction effect. The multifunctional structure comprises center frameworks made of high-elasticity high polymer materials and peripheral frameworks which surround the center frameworks in a connected mode and are made of high-elasticity high polymer materials. The center frameworks and every other peripheral framework are filled with flowing fillers with the heat absorption cooling effect. One or more small holes are formed in the side walls of the peripheral frameworks which are not filled with the fillers. The multifunctional structure further comprises high polymer material packaging layers for packaging the fillers. The peripheral frameworks which are not filled with the fillers are provided with or are not provided with the high polymer material packaging layers in a packaged mode. When the temperature of the environment where the multifunctional structure is located is higher than certain threshold temperature, the fillers start to absorb heat to achieve the cooling effect; after losing the heat absorption cooling effect, the fillers are placed into the environment with the temperature lower than the threshold temperature, and the cooling effect will be automatically recovered. Meanwhile, in the vibration process, the multifunctional structure is the equal of an elastic damper, and the vibration reduction effect is achieved by absorbing energy generated during vibration.
