Speed bump and speed bump system

A speed bump comprising:

• a base;
• a cover disposed opposite to the base and configured to be movable relative to the base;
• an electric-power generation device associated with the cover to scavenge energy through the cover and convert the energy into electrical energy;
• a first detection device for detecting a force condition of the cover and sending a first detection signal to a communication device when the cover is pressed;
• the communication device electrically connected to the first detection device and for sending a first communication signal when receiving the first detection signal,
• wherein the electric-power generation device is electrically connected to the communication device and the first detection device respectively to supply electric-power to the communication device and the first detection device,
• wherein the electric-power generation device comprises:
• a first transmission mechanism comprising a moving member and a rotating member, the moving member being coupled to the cover, the rotating member being rotatably disposed on the base, and the moving member being mated with the rotating member to convert a displacing movement of the moving member into a rotational movement of the rotating member;
• a second transmission mechanism comprising:
• a power input member coupled to the rotating member;
• a transmission shaft rotatably disposed on the base;
• a first overrun clutch disposed between the power input member and the transmission shaft, and coupling the power input member and the transmission shaft when the transmission shaft is rotated in a first direction;
• a power output member;
• and
• a second overrun clutch disposed between the power output member and the transmission shaft, and coupling the power output member and the transmission shaft when the transmission shaft is rotated in a second direction;
• an energy storage member coupled to the transmission shaft, and storing energy when the transmission shaft is rotated in the first direction and releasing energy when the transmission shaft is rotated in the second direction;
• and
• an electric-power generator coupled to the power output member.
