Description

Technical Field

[0001] The present invention relates to the technical field of road noise reduction, and in particular to a sound insulation device for road noise reduction. Background Art

[0002] Vehicles generate noise when driving on the road. This is the result of the interaction between tires and the road surface, road surface structure and material, vehicle speed, vehicle weight and load, tire design and condition, and environmental factors. Since the noise generated by vehicle driving is a kind of environmental pollution, it will affect the surrounding ecological environment and residents' lives. Therefore, it is necessary to achieve noise reduction by installing corresponding road noise reduction and sound insulation devices. Reducing road noise helps protect the environment and improve the quality of life of residents.

[0003] For example, the invention patent with application number 202120955958.1 discloses a sound insulation device for reducing road noise, including a substrate, and a sound insulation board above the substrate and vertically connected to the substrate. In the present invention, the sound insulation board is provided with a warning component at the end facing the road side. The warning component is fixedly connected to the sound insulation board, and the airflow generated when the car is driving is used as driving energy to drive the generator to operate. The electricity generated after the operation is stored in the battery provided in the battery box.

[0004] Based on the findings in the prior art, most of the existing sound insulation devices for road noise reduction have fixed structures and are generally installed on the road surface by bolts, which makes it inconvenient to disassemble and replace the sound insulation board after it is damaged, making it inconvenient to use. In addition, it is inconvenient to splice and assemble adjacent sound insulation devices, resulting in the adjacent sound insulation devices not being able to maintain alignment during actual use, thereby affecting the appearance and sound insulation effect and having low practicality. Therefore, the present invention proposes a sound insulation device for road noise reduction to solve the problems existing in the prior art. Summary of the Invention
