The mechanism of the gear generator 22 converts the mechanical energy of the vehicle passing through the speed bump 40 into electrical energy, and its electrical output terminal is connected to an external circuit to transmit the generated electrical energy to where it is needed, such as a traffic light or an energy storage system.

[0026] The hydraulic generator 26 comprises a liquid storage bag 25, hydraulic oil, a hydraulic generator 26 and a liquid storage tank 27; the liquid storage bag 25 is an annular liquid storage bag 25, which is filled with hydraulic oil.

[0032] The speed bump of the present application can be directly installed on the asphalt pavement, and utilizes the potential energy generated when vehicles pass through, which is converted into electrical energy and stored through its built-in power generation mechanism. This process not only provides energy for the speed bump 40 itself to achieve self-repair, but also provides power for the road traffic light system, reducing dependence on external power sources. After bearing the repeated pressure and friction of passing vehicles, it is inevitable that there will be gaps between the speed bump 40 and the road surface. These gaps will accelerate the damage of the speed bump 40 and increase the bumpy feeling when the vehicle passes by; the present invention automatically repairs these gaps through a self-heating mechanism, reducing maintenance requirements and improving driving stability. In addition, the installation-free design of the device allows it to be quickly deployed on the road without the need for complicated construction, and is suitable for various road environments.

When no vehicle passes, the liquid storage bag 25 is reset under the action of the second reset spring, so that the hydraulic oil flows from the liquid storage tank 27 through the second circulation pipeline and the first circulation pipeline back to the liquid storage bag 25 for secondary power generation. While reducing the speed of the vehicle, it also realizes the reuse and conservation of energy, which can reduce the dependence on traditional energy and reduce the energy cost of the city.
