[0019] Reference Figures 1 to 6 This utility model discloses a portable self-generating multifunctional power supply, including: a housing 100 and a self-generating device 200. The housing 100 is a semi-enclosed box. The housing 100 is composed of two components, which are arranged vertically opposite each other to facilitate the installation and disassembly and maintenance of other components. The housing 100 provides an installation base and protection for other components.

[0020] The self-generating device 200 includes a rocker arm 210, a transmission gear set 220, a power generation component 230, a storage battery 240, and a fastening screw 250. The power generation component 230 is disposed inside the housing 100, the transmission gear set 220 is disposed below the power generation component 230, the rocker arm 210 is disposed outside the housing 100, a second connecting hole 221 is provided below the transmission gear set 220, and an insertion hole 211 is provided on the rocker arm 210. The fastening screw 250 inserts the rocker arm 210 into the second connecting hole 221 through the insertion hole 211. The storage battery 240 is disposed inside the housing 100 and is electrically connected to the power generation component 230. One end of the rocker arm 210 is provided with a hand crank 212, and the other end of the rocker arm 210 is provided with a first connecting hole 213. When self-generating electricity is required, the fastening screw 250 is removed from the insertion hole 211, the rocker arm 210 is flipped over, and the first connecting hole 213 and the second connecting hole 221 are placed coaxially. At this time, the fastening screw 250 is used to set the rocker arm 210 on the transmission gear set 220 through the first connecting hole 213 and the second connecting hole 221. Rotating the hand crank 212 can drive the transmission gear set 220 to rotate, thereby generating electricity from the power generation component 230 and storing the electrical energy in the battery 240.

[0021] The joystick 210 is normally embedded in the housing 100 and secured with the fastening screw 250. Under normal circumstances, the joystick 210 does not affect the shape of the housing 100, making it easy to carry. When the battery 240 needs to be charged in the field, the joystick 210 is removed from the housing 100 and flipped over. The fastening screw 250 is then used to set the joystick 210 onto the transmission gear set 220 through the first connecting hole 213 and the second connecting hole 221. The operator holds the hand crank 212 and rotates the joystick 210, causing the transmission gear set 220 to rotate. This causes the self-generating device 200 to cut magnetic field lines, thereby generating electrical energy, which is stored in the battery 240. This design ensures that the battery 240 can still be charged even in harsh conditions such as when there is no external power source or sunlight in the field. Furthermore, the joystick 210 is embedded in the housing 100 under normal conditions and does not affect the shape of the housing 100, making it easy to carry.

[0022] Understandably, the outer surface of the casing 100 is designed to be smooth to avoid sharp structures and protect the user. The size and weight of this portable self-generating multi-functional power supply are set according to human usage habits and are not limited here.

The supercapacitor 300 is electrically connected to the power generation component 230 and the battery 240. The supercapacitor 300 is used to store the electrical energy generated by the power generation component 230 and store the electrical energy into the battery 240. Since the charging speed of the battery 240 is relatively slow, the electrical energy generated by the power generation component 230 is instantaneous. The supercapacitor 300 has the characteristic of fast energy storage, which can store the electrical energy instantaneously generated by the power generation component 230 and then store the electrical energy into the battery 240. The supercapacitor 300 temporarily stores the electrical energy generated by the power generation component 230. A power management module is installed in the control circuit. The supercapacitor 300 charges the temporarily stored electrical energy into the battery 240 through the power management module.
