Description

Technical Field

[0001] The utility model relates to the technical field of automobile power generation, in particular to a composite energy generator used for motor vehicle energy collection. Background Art

[0002] With the continuous update and iteration of new technologies such as intelligent driving and automotive Internet of Things, more and more vehicle-mounted sensors are used in various locations of the car, achieving safe, comfortable and efficient driving. The embodiment of these advantages means that the vehicle-mounted sensor network is becoming more and more complex. The complex wiring and a large number of sensor nodes have brought tremendous pressure to the design of the car body and the supply of energy. Therefore, the development of wireless, clean and self-powered devices has become a key issue that needs to be solved in the development of the next generation of automotive sensor networks. The Chinese application with application number CN115800814A discloses a novel power generation device utilizing temperature difference-vibration hybrid energy, comprising: equipment; a thermoelectric generator comprising a hot end and a cold end with a temperature difference, the hot end being connected to the equipment, and the cold end being arranged opposite to the hot end; a cold row being connected to the cold end, a micro-flow pump being arranged on the liquid inlet of the cold row, and being used to push the coolant to bring the heat in the cold end to the cold row, and flowing back to the cold end to form a cooling circulation loop; an electric energy extraction management unit being arranged at the power output end of the thermoelectric generator, wherein a metal elastic thin plate is arranged in the pump cavity of the micro-flow pump, and a one-way valve is arranged on the liquid inlet and liquid outlet of the micro-flow pump, and the metal elastic thin plate is connected to the equipment, and is used to absorb the vibration energy of the equipment, so that the coolant actively dissipates heat to the cold end. The present invention utilizes the temperature difference between the heat source of the equipment and the ambient temperature to generate electricity, and at the same time, the cold end of the thermoelectric generator increases the temperature difference by actively dissipating heat, thereby improving the power generation efficiency. Although it can convert the temperature difference-vibration hybrid energy into electric energy, its structure is scattered, and it cannot be small and integrated to meet the use of motor vehicles. Therefore, it is necessary to invent a technology based on electromagnetic power generation and temperature difference energy generation, which can convert the vibration energy and thermal energy of motor vehicles into electrical energy for powering sensors and other equipment.
