Problems solved by technology
[0002] The rapid development of science and technology has led to the better and better shock absorption performance of current civilian vehicles, which has led to the fact that many vehicles do not slow down when passing speed bumps, making the speed bumps unable to achieve the purpose of deceleration. Is it a great safety hazard for the car owner or the surrounding pedestrians?
[0003] But if we increase the slope of the speed bump, it will increase the burden on the cars with poor shock absorption performance and slow speed, and most of the speed bumps are made of rubber, and they work for a period of time Due to the extensive use of speed bumps and the wide range of use, many speed bumps cannot be replaced quickly after damage

The invention discloses a self-powered deceleration strip adjusting device based on a PVDF piezoelectric material. The self-powered deceleration strip adjusting device based on the PVDF piezoelectricmaterial comprises a deceleration strip body, an adjusting mechanism for driving the deceleration strip body to ascend and descend, and a speed measuring device for monitoring the speed of a passing vehicle. By arranging the deceleration strip made of the PDVF piezoelectric material, the adjusting mechanism comprising the storage battery and the lifting mechanism and the speed measuring device, the height of the deceleration strip body is adjusted according to the speed of passing vehicles, and the deceleration effect of the deceleration strip is guaranteed; efficient charging is achieved by arranging a single-arch-shaped power generation module and a second piezoelectric power generation assembly, wherein the single-arch-shaped power generation module is formed by bonding and stacking anupper supporting protection plate, an upper electrode plate, a PVDF piezoelectric film, a lower electrode plate and a lower supporting protection plate in a multi-layer mode, and the second piezoelectric power generation assembly comprises an elastic block and a piezoelectric power generation fast block.
Description
technical field [0001] The invention relates to the field of piezoelectric power generation, in particular to a self-powered speed bump adjustment device based on PVDF piezoelectric material. Background technique [0002] The rapid development of science and technology has led to the better and better shock absorption performance of current civilian vehicles, which has led to the fact that many vehicles do not slow down when passing speed bumps, making the speed bumps unable to achieve the purpose of deceleration. It is a great safety hazard for the car owner or the pedestrians around. [0003] But if we increase the slope of the speed bump, it will increase the burden on the cars with poor shock absorption performance and slow speed, and most of the speed bumps are made of rubber, and they work for a period of time Due to the extensive use of speed bumps and the wide range of use, many speed bumps cannot be replaced quickly after damage. Therefore, we need a speed bump th...
