Simultaneously, it can connect to mains power through the mains power interface 4 to supply power to the battery pack 5, ensuring that the battery pack 5 provides stable power support to electrical equipment. This allows the power supply device to be portable while ensuring power supply stability during long-term outdoor use.
[0040] This utility model provides a power supply device, which includes a housing, a solar power supply module, a hand-cranked power supply module, a mains power interface, and a battery pack. It integrates the solar power supply module and the hand-cranked power supply module to make full use of outdoor environmental conditions. At the same time, it can be connected to the mains power supply through the mains power interface to supply power to the battery pack, ensuring that the battery pack provides stable power support to electrical equipment. This allows the power supply device to be portable while ensuring power supply stability during long-term use in outdoor environments.
[0041] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 3As shown, the hand-cranked power supply module 3 includes a generator body 31, a drive shaft 32, a telescopic arm 33, and a crank handle 34. The generator body 31 is located on an inner wall of the housing 1. One end of the drive shaft 32 is connected to the generator body 31, and the other end extends to the outside of the housing 1. The telescopic arm 33 rotates up and down around the other end of the drive shaft 32. The end of the telescopic arm 33 away from the drive shaft 32 is connected to the crank handle 34. The crank handle 34 is perpendicular to the telescopic arm 33. When the hand-cranked power supply module 3 is used to supply power, the crank handle 34 is first rotated at a certain speed, which sequentially drives the telescopic arm 33 and the drive shaft 32 to move, and finally drives the rotor of the generator body 31 to rotate and cut the magnetic field lines, thereby realizing hand-cranked power generation. The generated electrical energy is rectified and filtered before outputting a DC voltage to charge the battery pack 5, which improves the power supply stability of the power supply device.
[0042] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 3 As shown, the crank handle 34 is rotatably connected to the telescopic arm 33. After rotating 90 degrees, the crank handle 34 is stored on one side of the telescopic arm 33. When using the hand-cranked power supply module 3, the crank handle 34 is unfolded for operation. After use, the crank handle 34 is rotated until it folds with the telescopic arm 33. Furthermore, by adjusting the gear ratio, the crank handle 34 can be rotated at a certain speed for comfortable operation. The crank handle 34 has a simple structure, a stable connection, and is easy to store, improving the portability of the power supply device and the comfort of using the hand-cranked power supply module 3.
[0043] As an optional implementation, in one embodiment of the invention, a motor and a speed increaser are also provided. The motor is located inside the housing 1, and its input end is connected to the output end of the solar power supply module 2. The speed increaser is connected to the motor's rotating shaft and the drive shaft 32. The solar power supply module 2 adopts an independent photovoltaic power generation method, using the solar panel 21 to directly convert light energy into electrical energy. The output electrical energy charges the battery pack 5 on one hand, and transmits kinetic energy to the hand-cranked power supply module 3 through the motor to assist the hand-cranked power supply module 3 in generating electricity. In this embodiment of the invention, the motor's rotating shaft, the speed increaser, and the drive shaft 32 of the generator body 31 are connected. The solar power supply module 2 generates a photoelectric voltage, and the generated electrical energy first drives the motor. The rotation of the motor's rotating shaft drives the speed increaser to rotate. The speed increaser provides an auxiliary force to the drive shaft 32 of the generator body 31, making it easy to turn the crank 34. The drive shaft 32 drives the generator rotor to rotate at high speed, cutting magnetic field lines. When the speed reaches the rated speed, it will generate an induced electromotive force of 30W to charge the battery pack 5. This utility model embodiment converts electrical energy into kinetic energy through a solar power supply module 2, and then uses the force generated by the speed increaser to assist the rotation of the drive shaft 32 of the generator body 31, which greatly reduces the force required by the user to crank the handle 34 and can increase the rotation speed and increase the efficiency of the hand-cranked power supply module 3.
[0044] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the solar power module 2 includes a solar panel 21 and a controller. The solar panel 21 is movably mounted on the housing 1. The two ends of the controller are connected to the solar panel 21 and the motor, respectively. The controller digitally regulates the current generated by the solar panel 21 and incorporates multi-level charge and discharge protection, ultimately supplying a stable current to the motor.
[0045] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 2 As shown, the solar power module 2 also includes a telescopic bracket 22. The two ends of the telescopic bracket 22 are connected to the inner wall of the housing 1 and the solar panel 21, respectively. The telescopic bracket 22 is a telescopic structure, and the housing 1 has an opening slot to accommodate the solar panel 21. When generating electricity using the solar power module 2, the solar panel 21 is removed, the solar cell cavity is opened, the telescopic bracket 22 is extended to its longest position to extend the solar panel 21 outwards, the solar panel 21 is unfolded, and the angle is adjusted to allow sunlight to shine onto the solar panel 21, generating a photoelectric voltage.
[0046] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 2As shown, the solar panel 21 is a foldable solar panel. The foldable solar panel 21 is different from the traditional solar panel. It is made of lightweight materials, is easy to carry, and can be folded into a small volume. It is especially suitable for outdoor activities or emergency use. The foldable solar panel 21 is easy to fold and store inside the housing 1, which improves the convenience of the power supply device and reduces the size of the power supply device.
[0047] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, two support pads 6 are also provided. The two support pads 6 are respectively located on the bottom sides of the housing 1. The support pads 6 provide a stable support surface to support the entire power supply device, and can adjust the tilt of the device on uneven ground, thereby improving the stability and adaptability of the power supply device.
