Description

technical field [0001] The invention relates to a power generation device utilizing the vibration energy of a vehicle, in particular to a power generation device for a road deceleration belt. Background technique [0002] At present, in road sections and places where vehicles are relatively concentrated, in order to reduce traffic accidents and limit vehicle speeds, a number of speed reduction belts are mostly set on the road surface to reduce vehicle speed. Ordinary speed bumps are fixed on the road. Although the vehicle can achieve the purpose of deceleration when passing the speed bump, it consumes some extra energy of the car and brings unnecessary energy waste. [0003] In order to use speed bumps to recover the vibration energy of vehicles, there are currently some invention patents for road speed bump power generation devices. For example, the publication number CN101285455, a road deceleration belt power generation device, includes an upper platen, an upper base pla...

Problems solved by technology

[0005] At present, similar speed bump power generation devices mainly have the following deficiencies: (1) the existing patents do not "fully utilize the energy generated in the two processes of the speed bump up and down and store and collect the energy of the vehicle passing through the speed bump. Time to release" These two problems are coordinated and solved, resulting in low power generation efficiency

(2) For the generator, when the rotation speed is lower than the minimum rotation speed of the generator, the energy collection continues at this time, which affects the opening of the next energy recovery process on the one hand, and on the other hand affects the efficiency of the generator due to the low rotation speed

Combining these two factors, if the generator speed is too slow, the energy collection density will decrease and the battery charging efficiency will decrease.
