[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0029] Example 1 is a portable power generation device, which has:

[0030] Bracket 1;

[0031] Photovoltaic module 2 can be installed on bracket 1. Both ends of photovoltaic module 2 are equipped with connecting plates 3 that can be bent downwards via hinges 2-2. The connecting plates 3 are provided with a clamping mechanism 4 that can be clamped onto the side wall of bracket 1.

[0032] Inverter 5 is mounted on bracket 1 and can be electrically connected to photovoltaic module 2. After the photovoltaic module 2 is laid on bracket 1, the connecting plates 3 at both ends of the photovoltaic module 2 are bent downwards and secured to the side walls of bracket 1 by clamping mechanisms 4. This secures the photovoltaic module 2 to bracket 1, and the combined action of multiple clamping mechanisms 4 ensures good stability for the bracket 1 and the photovoltaic module 2 as a whole.

[0033] Example 2 is a portable power generation device. Based on Example 1, in this example, the photovoltaic module 2 is composed of at least two strip-shaped photovoltaic panels 2-1 spliced ​​together. Adjacent photovoltaic panels 2-1 are connected by hinges 2-2, and the same end of adjacent photovoltaic panels 2-1 is connected by a connecting wire. Thus, after the photovoltaic module 2 is removed from the support 1, it can be folded by the hinges 2-2, facilitating its storage and transportation. The connection between the same end of adjacent photovoltaic panels 2-1 ensures that when the photovoltaic module 2 is connected to the inverter 5, the inverter 5 and each photovoltaic panel 2-1 are connected in parallel.

[0034] Example 3 is a portable power generation device. Based on Example 1, in this example, the mounting mechanism 4 has a mounting block 4-1 mounted on the connecting plate 3. The mounting block 4-1 has a mounting hole. A rod 4-2 that can slide and engage with the mounting hole along the axial direction of the mounting hole is mounted on the mounting block 4-1. A pin head 4-3 with a diameter larger than the mounting hole is mounted on the end of the rod 4-2 facing the bracket 1. A positioning hole 1-12 that engages with the shaft hole of the pin head 4-3 is made on the side wall of the bracket 1 at the position corresponding to the pin head 4-3. A spring 4-4 ​​is fitted on the rod 4-2 between the pin head 4-3 and the mounting block 4-1. A limiting block 4-5 with a diameter larger than the mounting hole is mounted on the end of the rod 4-2 that extends out of the mounting block 4-1. A pull ring 4-6 is mounted on the limiting block 4-5. Thus, after the photovoltaic module 2 is installed on the bracket 1, the connecting plate 3 is bent downwards and the pull ring 4-6 is pulled outwards, so that the pin head 4-3 on the connecting plate 3 is positioned corresponding to the positioning hole 1-12 on the bracket 1. After releasing the pull ring 4-6, the pin head 4-3 can be inserted into the positioning hole 1-12 under the action of the spring 4-4. With the cooperation of the pin head 4-3 and the positioning hole 1-12, the photovoltaic module 2 is installed on the bracket 1. By pulling the pull ring 4-6 outwards, the cooperation between the pin head 4-3 and the positioning hole 1-12 can be canceled, thereby facilitating the removal of the photovoltaic module 2 from the bracket 1, realizing convenient installation and removal of the photovoltaic module 2.

[0035] Example 4 is a portable power generation device. Based on Example 1, in this example, a hanging frame 1-1 is installed on the bracket 1, with the opening of the hanging frame 1-1 facing upwards. A hook 5-1 that can be inserted into the hanging frame 1-1 is installed on the inverter 5, and heat dissipation fins 5-2 are installed on the inverter 5. In this way, it is convenient to install the inverter 5 on the bracket 1 by cooperating with the hook 5-1.

[0036] Example 5 is a portable power generation device. Based on Example 1, in this example, the support 1 has two parallel crossbeams 1-2, and the two crossbeams 1-2 are connected by support leg structures at both ends of the crossbeams 1-2.

[0037] The support leg structure has a first support leg 1-3 mounted on a first crossbeam 1-9 and a second support leg 1-4 mounted on a second crossbeam 1-10. The first support leg 1-3 and the second support leg 1-4 are arranged in an "X" shape and are connected by a hinge 2-2. Thus, the bracket 1, composed of the crossbeam and the "X"-shaped support leg structure, has a simple structure while also possessing good structural strength.

[0038] The first support leg 1-3 has a first connecting post 1-5 and a second connecting post 1-6 arranged in parallel. The first connecting post 1-5 and the second connecting post 1-6 are connected by a first connecting rod 1-7. The first connecting post 1-5, the second connecting post 1-6, and the first connecting rod 1-7 are generally arranged in a "Z" shape. The second support leg 1-4 is arranged between the first connecting post 1-5 and the second connecting post 1-6, and the second support leg 1-4 is connected to the first connecting rod 1-7 by a hinge 2-2. In this way, after the second support leg 1-4 rotates relative to the second connecting rod 1-8 to a corresponding angle, the first connecting post 1-5 and the second connecting post 1-6 limit the second support leg 1-4, so that the support leg structure can be limited when it is opened to the corresponding position. Furthermore, when the support leg structure is stored, the first support leg 1-3 and the second support leg 1-4 can be arranged in parallel under the action of the first connecting rod 1-7, which is convenient for carrying.

[0039] Second connecting rods 1-8 are bolted to both ends of the crossbeam frame 1-2, and the ends of the support leg structure are bolted to the second connecting rods 1-8.

[0040] The crossbeam frame 1-2 is composed of a first crossbeam 1-9 and a second crossbeam 1-10 spliced ​​together. A support leg structure connects the two crossbeam frames 1-2 at the splicing position of the first crossbeam 1-9 and the second crossbeam 1-10. In this way, by setting the support leg structure in the middle of the crossbeam frame 1-2, the structural strength of the bracket 1 composed of the crossbeam frame 1-2 and the support leg structure can be enhanced.

[0041] A third connecting rod 1-11 connects the first crossbeam 1-9 and the second crossbeam 1-10. The third connecting rod 1-11 is T-shaped. The first crossbeam 1-9 is bolted to the first end of the third connecting rod 1-11, and the second crossbeam 1-10 is bolted to the second end of the third connecting rod 1-11. The end of the support leg structure is bolted to the third end of the third connecting rod 1-11.
