Description

Technical Field

[0001] The utility model relates to the technical field of solar power generation, in particular to a foldable solar power supply device. Background Art

[0002] Solar energy refers to the sun's thermal radiation, primarily manifested in sunlight. In modern times, it's commonly used to generate electricity or power water heaters. Since the dawn of life on Earth, life has primarily relied on the sun's thermal radiation. Humans have also used sunlight to dry objects and prepare food, such as making salt and drying salted fish. As fossil fuels become increasingly scarce, solar energy has become a vital component of human energy and continues to grow. Solar energy can be harnessed through two methods: photothermal conversion and photovoltaic conversion. Solar power generation is an emerging renewable energy source.

[0003] A photovoltaic module is a power generation device that generates direct current (DC) electricity when exposed to sunlight. It consists of solid-state photovoltaic cells made almost entirely of semiconductor materials, such as silicon. Simple photovoltaic cells can power watches and computers, while more complex photovoltaic systems can provide lighting for homes, traffic lights, and surveillance systems, feeding into the electrical grid. Photovoltaic panels can be made into various shapes and connected to generate more electricity. Photovoltaic panels can be used on rooftops and building surfaces, and can even be incorporated into windows, skylights, or as part of window shades. These photovoltaic installations are often referred to as building-attached photovoltaic systems.

[0004] The drawback of existing equipment is that while the total amount of solar radiation reaching the Earth's surface is enormous, the energy flux density is very low. Therefore, achieving a certain level of power generation efficiency when utilizing solar energy often requires photovoltaic panels of a certain area. However, existing photovoltaic panels for outdoor use are often small in size for portability, which undoubtedly affects the panels' power generation efficiency. Utility Model Content

[0005] The purpose of the present invention is to provide a foldable solar power supply device to solve the problems raised in the above background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0007] A foldable solar power supply device includes a power generation mechanism, a fixing mechanism, and a connecting mechanism. The power generation mechanism includes a first photovoltaic power generation panel, a second photovoltaic power generation panel, a third photovoltaic power generation panel, and a fourth photovoltaic power generation panel. The first photovoltaic power generation panel and the second photovoltaic power generation panel, the second photovoltaic power generation panel and the third photovoltaic power generation panel, and the third photovoltaic power generation panel and the fourth photovoltaic power generation panel are all rotatably connected through the connecting mechanism. The fixing mechanism includes a first fixing member and a second fixing member. The first fixing member fixes the folded first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel together, and the second fixing member fixes the unfolded first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel together.

[0008] The beneficial effect of adopting the above-mentioned further scheme is that the power generation area of ​​the photovoltaic panel is increased by the first photovoltaic panel, the second photovoltaic panel, the third photovoltaic panel, and the fourth photovoltaic panel, thereby improving the power generation efficiency, and the first photovoltaic panel, the second photovoltaic panel, the third photovoltaic panel, and the fourth photovoltaic panel are transformed into a cube by using a connecting mechanism, and the first photovoltaic panel, the second photovoltaic panel, the third photovoltaic panel, and the fourth photovoltaic panel are fixed by using a fixing mechanism, so as to achieve the purpose of being easy for users to carry.

[0009] Furthermore, the connecting mechanism includes several pairs of connecting seats and several pairs of connecting plates. Several pairs of the connecting seats are respectively installed on both sides of the second photovoltaic power generation panel and one side of the third photovoltaic power generation panel. Several pairs of the connecting plates are respectively installed on one side of the first photovoltaic power generation panel, the other side of the third photovoltaic power generation panel, and one side of the fourth photovoltaic power generation panel.

[0011] The beneficial effect of adopting the above further scheme is that, by utilizing the rotating shaft and the connecting plate, the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel have the ability to rotate independently, and by utilizing the first limiting bar, when the angle between the first photovoltaic power generation panel and the second photovoltaic power generation panel or between the second photovoltaic power generation panel and the third photovoltaic power generation panel or between the third photovoltaic power generation panel and the fourth photovoltaic power generation panel is at 180 degrees, the connecting plate will offset the first limiting bar, and at this time the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel can no longer rotate, and by utilizing the first limiting bar The second limit bar, when the angle between the first photovoltaic power generation panel, the second photovoltaic power generation panel, or between the second photovoltaic power generation panel and the third photovoltaic power generation panel, or between the third photovoltaic power generation panel and the fourth photovoltaic power generation panel is at 90 degrees, the connecting plate will offset the second limit bar. At this time, the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel and the fourth photovoltaic power generation panel can no longer rotate, thereby achieving the purpose of limiting the rotation angle of the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel and the fourth photovoltaic power generation panel. By using the grooves, the first limit bar and the second limit bar will not hinder the reverse rotation of the connecting plate.

[0012] Furthermore, the first fixing member includes four groups of first connecting shafts and four groups of first fixing rods, and the four groups of the first connecting shafts and the four groups of the first fixing rods are respectively installed on one side of the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that after the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel are folded into a cube, a pair of first connecting bars and the second connecting bars can be rotated so that the first fixing rods on the adjacent photovoltaic panels are stuck in the first slots, and then the first screw is tightened to fix the pair of first connecting bars and the second connecting bars together, thereby fixing the folded first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel together.

[0014] Furthermore, the second fixing member includes three groups of second connecting shafts and three groups of second fixing rods. The three groups of second connecting shafts are respectively installed on the other side of the first photovoltaic power generation panel, the second photovoltaic power generation panel, and the third photovoltaic power generation panel. The three groups of second fixing rods are respectively installed on the other side of the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel.

The tail end of the fourth connecting bar is installed with a fourth fixing block. A second screw is slid inside the fourth fixing block, and the second screw and the internal thread of the third fixing block are engaged.

[0016] Furthermore, the lengths of the second photovoltaic power generation panel and the third photovoltaic power generation panel are equal, the length of the first photovoltaic power generation panel is smaller than the length of the second photovoltaic power generation panel, the length of the fourth photovoltaic power generation panel is larger than the length of the second photovoltaic power generation panel, and the side surface of the fourth photovoltaic power generation panel is in contact with the top surface of the first photovoltaic power generation panel.

[0017] The beneficial effect of adopting the above further scheme is that by limiting the length of the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel, the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel can be folded into a cube.

[0018] Furthermore, a first bracket is installed on the bottom surface of the second photovoltaic power generation panel, and a pair of second brackets are installed on the bottom surface of the fourth photovoltaic power generation panel, and the first bracket and the pair of second brackets are both hollowed out.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that the first bracket and a pair of second brackets are used to provide support for the unfolded first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel. Because the pair of second brackets are hollow, after the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel are folded into a cube, the user can hold the pair of second brackets to carry the photovoltaic panel.

[0020] Compared with the existing technology, the beneficial effect of the present invention is that the foldable solar power supply equipment increases the power generation area of ​​the photovoltaic panel through the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel, thereby improving the power generation efficiency, and utilizes a connecting mechanism to enable the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel to be transformed into a cube, and utilizes a fixing mechanism to fix the first photovoltaic power generation panel, the second photovoltaic power generation panel, the third photovoltaic power generation panel, and the fourth photovoltaic power generation panel, thereby achieving the purpose of being easy for users to carry.
