Description

Technical Field

[0001] The utility model relates to the field of photovoltaic components, and more specifically, to a portable photovoltaic energy storage device. Background Art

[0002] Solar energy refers to the sun's thermal radiation, primarily manifested in sunlight. As a green, clean, pollution-free, and inexhaustible energy source, solar energy is increasingly gaining popularity, leading to the emergence of a wide variety of solar power generation devices. Solar power generation devices primarily consist of solar panels, solar control boxes, and batteries. The solar panel is the core component of a solar power generation device and the most valuable element in a solar power generation system. Its function is to convert solar energy into electricity, either for storage in batteries or to power a load.

[0003] However, traditional energy storage photovoltaic power generation devices are usually large in size, and the photovoltaic panels do not have a storage function. They will take up a large space when not in use, which usually makes them inconvenient to carry and cannot be used quickly. Their overall practical effect remains to be discussed.

[0023] See also Figure 1-3 A portable photovoltaic energy storage device includes a set of fixed frames 1 and two sets of movable frames 2 for installing solar panels 7. The two sets of movable frames 2 are movably arranged at the upper and lower ends of the fixed frame 1 respectively. The right side of the upper end of the fixed frame 1 and the left side of the lower end of the fixed frame 1 are fixedly connected with bending blocks 3, and the bending blocks 3 are clamped at the corners of the movable frame 2. Two sets of L-shaped bending parts 4 are also provided on the front of the fixed frame 1. A limit pin 5 is provided on the outer side of the L-shaped bending part 4 for horizontal movement. A limit hole 6 is also provided on the outer side of the movable frame 2 for facilitating the clamping of the limit pin 5. A stopper 501 is fixedly connected to the outer end of the limit pin 5. The stopper 501 is connected to the outer side of the L-shaped bending part 4 by a spring 502. The spring 502 is in a retracted state under the default state.

[0024] Based on the above structure, when the device is in use, the movable frame 2 is stacked on the upper and lower ends of the fixed frame 1, and is fixed on the outside of the fixed frame 1 by the bent clamping block 3 at the corner position, which makes it easy to carry and reduces the overall space occupied. In addition, when in use, the movable frame 2 is pulled out of the bent clamping block 3 on the outside of the fixed frame 1, and the two sets of movable frames 2 at the upper and lower ends of the fixed frame 1 are slid and unfolded until the limit pin 5 inserted on the outside of the L-shaped bending part 4 is docked with the limit hole 6 on the outside of the movable frame 2. Under the elastic contraction of the spring 502, the limit pin 5 is driven to be engaged in the limit hole 6. After the unfolding is completed, the movable frame 2 is relatively fixed on the outside of the fixed frame 1, which is conducive to the use of the solar panel 7 in the frame for photovoltaic power generation. The operation is also very portable and practical.

[0025] The fixed frame 1 is provided with slide rails 101 at both ends, and the movable frame 2 is provided with a slide groove 201 on one side of the movable frame 2 that is connected to the slide rail 101. The slide rail 101 is a T-shaped slide rail, and the slide groove 201 is a T-shaped slide groove. The contact surface between the slide rail 101 and the slide groove 201 is a smooth surface structure. The T-shaped structure prevents the movable frame 2 from detaching from the upper and lower ends of the fixed frame 1 and falling. The smooth surface design facilitates the movable frame 2 to slide smoothly outside the fixed frame 1, and then unfold and use the solar panels 7 installed on the frame.

[0026] Among them, the contact surface between the bending block 3 and the movable frame 2 is provided with a rubber pad 301. After the upper and lower groups of movable frames 2 are stacked on the outside of the fixed frame 1, the rubber pad 301 on the contact surface of the bending block 3 is used to frictionally engage with it, thereby maintaining the relative stability of the engagement and maintaining the stability of the movable frame 2 during carrying.
