It reduces the dependence on disposable batteries <72> and reduces the pollution to the environment caused by the abandonment of batteries <72>.

[0038] Based on the hand-cranked solar power supply, the present application adopts the following implementation scheme:

[0039] It includes a solar mobile power supply main body 10 and an independent power generation module 20.

The independent power generation module 20 plays the role of power generation. It uses the electromagnetic generator 21 and generates power through the hand crank to operate the electromagnetic generator 21. The main body 10 of the solar mobile power supply and the independent power generation module 20 are set as two independent detachable structures. After the solar mobile power supply and the independent power generation module 20 are assembled, they are in electrical contact through the metal conductive structure 60 provided between them. When the hand crank is rotated, the electric energy generated by the electromagnetic generator 21 will be transmitted to the main body 10 of the solar mobile power supply, so as to charge the main body 10 of the solar mobile power supply. In addition, when the hand-cranked solar power supply has no power and cannot be charged by solar energy and is unusable, in order to facilitate the operation of the independent power generation module 20 and prevent the power supply of the hand crank from being restricted due to the power consumption of electrical components such as the internal circuit of the main body 10 of the solar mobile power supply; the independent power generation module 20 can be detached separately, and then connected to the USB interface 22 and the electrical device through the data cable. At this time, when the hand crank is operated to run the electromagnetic generator 21, the electric energy generated by the electromagnetic generator 21 can be directly supplied to the electrical device, without partial loss caused by the need for the electric energy to pass through the main body 10 of the solar mobile power supply, and the user can directly operate the independent power generation module 20 without carrying the main body 10 of the solar mobile power supply together, which can reduce the burden on the user to turn the hand crank.

[0041] The solar mobile power supply assembles the independent power generation module 20 by using the fixed slot 11, and achieves directional assembly and a fixed form after assembly by setting the guiding sliding structure 30 and the elastic buckle 40 structure between the fixed slot 11 and the independent power generation module 20.

The holding portion 54 is inserted into the jack 23 by the rotation of the rotating arm 53 along the hinge seat 52, so that the whole rocking handle 50 is fixed to the independent power generation module 20; when the hand crank is needed, the swing arm is turned over 180 degrees along the hinge seat 52, so that the holding portion 54 can be withdrawn from the jack 23 and turned upwards. At this time, the holding portion 54 can be held to drive the rotation of the rotating arm 53, thereby driving the turntable 51 to rotate to operate the electromagnetic generator 21; when not in use, after the rotating handle is turned over along the hinge seat 52 until the holding portion 54 is inserted into the jack 23, the hand crank can be kept in a fixed state on the independent power generation module 20; in order to keep the hand crank in the stored and fixed state, a bushing 56 is provided at one end of the rotating arm 53 connected to the hinge seat 52, and the bushing 56 is in abutting fit with the turntable 51.
