Description

Technical Field

[0001] The utility model specifically relates to a double-row solar folding panel, belonging to the technical field of outdoor portable solar photovoltaic power generation. Background Art

[0002] Outdoor portable solar photovoltaic panels can be carried with you or in your car. After unfolding, they can receive sunlight and convert light energy into electrical energy outdoors during the day to power outdoor electronic devices or charge energy storage power supplies. When the solar panel is generating electricity, its photoelectric conversion efficiency is the highest when the light is perpendicular to the surface of the solar panel. Therefore, the solar panel is generally set at a certain angle, i.e., an inclination angle, to the ground through a bracket to maximize the power generation. Outdoor portable solar photovoltaic panels in the prior art are usually used in a single row. Some single-row photovoltaic panels include multiple small panels that can be folded together for easy carrying. When the power of the solar panel needs to be increased, the length of the single-row photovoltaic panel can only be extended, and two rows of solar panels cannot be set in the width direction, because the existing bracket can only support the lower row of solar panels at a certain angle to the ground, but cannot simultaneously support the upper row of solar panels to maintain the same inclination angle, thereby limiting the application of double-row solar folding panels.

DETAILED DESCRIPTION

[0028] The utility model is clearly and completely described below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-7As shown, a double-row solar folding panel includes a lower row of power generation panels 1 and an upper row of power generation panels 2. Each row of power generation panels includes four solar panels 3, which are aligned and symmetrically arranged up and down, and the whole constitutes a double-row eight-piece solar folding panel. One or more series-parallel photovoltaic cells are arranged inside the solar panel 3. There can be many types of photovoltaic cells, such as monocrystalline silicon cells, polycrystalline silicon cells, thin-film cells, CIGS cells, perovskite cells, etc. Photovoltaic cells can absorb sunlight and convert light energy into electrical energy. The solar panel includes a front and a back, and the front is the light-receiving surface. The lower row of power generation panels 1 and the upper row of power generation panels 2 are manufactured through an integrated molding lamination process. They are a whole and can be cut and sheared as needed later. They belong to lightweight flexible solar photovoltaic power generation panels. Their composition structure from top to bottom can be as follows: ETFE / EVA / cell / EVA / epoxy board / EVA / ETFE. During manufacturing, cells are placed in the power generation area and connected with wires, and no cells are placed in the non-power generation area; the power generation area can be slightly bent, and the non-power generation area can be greatly bent. Its structural composition and lamination manufacturing process belong to the scope of the prior art. In this example, a protruding protective plate 4 is also provided on one side of the lower row of power generation panels 1. No cells are provided in the protective plate 4. A junction box 41, a handle 42 and two 43 straps are fixedly connected to the protective plate 4. The junction box 41 is electrically connected to the cells inside the solar panel to lead out the generated voltage and current. A plurality of hollow portions 11 of different shapes are cut out between the lower row of power generation panels 1 and the upper row of power generation panels 2, and between the adjacent solar panels 3 of each row of power generation panels. These hollow portions avoid the cell area and do not affect power generation. The arrangement of these hollow portions makes it easier to fold. When folding, the light-receiving surfaces of the lower row of power generation panels 1 and the upper row of power generation panels 2 are relatively aligned and folded together, and then the adjacent solar panels can be folded together, and finally the protective plate 4 and the binding straps 43 are used to cover and bind the folded solar panels together as a whole. Figure 7 As shown, the whole is similar to a briefcase, and can be conveniently moved and carried by holding the handle 42.

[0031] After the double-row foldable solar panels are unfolded, three sets of bracket assemblies 6 are fixedly arranged on the back of the lower row of power generation panels 1. Each set of bracket assemblies 6 includes a first support plate 61. The upper end of the first support plate 61 is fixedly connected to the upper part of the lower row of power generation panels 1. Initially (when stored), the first support plate 61 is parallel to the back of the lower row of power generation panels 1 (see Figure 6 ), the lower end of the first support plate 61 is connected to the lower row of power generation panels by a snap button 611, and the two can be locked or opened by the snap button. When in use, open the snap button so that the lower end of the first support plate 61 is opened to a certain angle relative to the lower row of power generation panels 1 (see Figure 2), at this time, the connection between the upper part of the first support plate and the lower row of power generation panels is bent, so that the first support plate can support the lower row of power generation panels; in order to control the opening angle, the bracket assembly also includes a first webbing 63, which has a certain elasticity. The first webbing 63 is located between the first support plate 61 and the back of the lower row of power generation panels 1. The lower end of the first webbing 63 is fixedly connected to the lower edge of the lower row of power generation panels 1, and the upper end of the first webbing 63 is fixedly connected to the upper part of the first support plate 61. In this way, by controlling the length of the first webbing, when the first support plate 61 is opened and the first webbing 63 is tightened, a triangular state is formed (see Figure 5 ), the angle between the first support plate and the lower row of power generation panels can be fixed and flexibly adjusted.

[0032] A second support plate 62 is also provided on the upper part of the first support plate 61. The second support plate 62 is a rectangular portion cut out from the middle plane of the first support plate 61 through three sides, that is, the first support plate 61 covers the second support plate 62, and the upper end of the second support plate 62 is a fixed end, which is fixedly connected to the upper part of the lower support plate 61, so that the fixed end of the second support plate and the first support plate remain connected as a whole. The other end of the second support plate 62 is a free end. Initially, the second support plate 62 is parallel to and close to the middle of the first support plate 61 (see Figure 6 ), when in use, the free end of the second support plate 62 opens a certain angle relative to the first support plate 61, at this time, the root of the second support plate is bent at the connection with the first support plate, and the free end head of the second support plate 62 is abutted against the back of the upper row of power generation panels 2, so that the second support plate 62 can support the upper row of power generation panels 2. The free end head of the second support plate 62 is connected to the back of the upper row of power generation panels 2 by Velcro, and the Velcro includes two parts, namely, a velcro surface and a hook surface. The velcro surface and the hook surface cooperate with each other and can be pasted together or torn apart. For example, a Velcro hook surface 21 is adhesively fixedly provided on the back of the upper row of power generation panels 2, and the Velcro pasted on the back of the upper row of power generation panels has a certain length in the vertical direction, and a Velcro vel ...

[0033] The first support plate 61 and the second support plate 62 are required to have a certain rigidity to form an effective support, and at the same time have a certain flexibility and toughness to facilitate bending and recovery. They are also required to be light in weight. Their material can be an epoxy glass fiber board with a certain thickness, which is laminated into one piece through a lamination process and cut into the required shape.

[0034] The overall weight of the double-row solar folding panel is relatively light. When it is supported and unfolded for use, in order to prevent it from being blown or deformed by the wind, a plurality of fixing holes 12 are provided at the four corners or edges of the lower row of power generation panels and the upper row of power generation panels. By tying the fixing holes with ropes, the double-row solar folding panels can be effectively fixed to adapt to windy weather conditions.

[0035] Example 2

[0036] like Figure 8-10 As shown, another double-row solar folding panel also includes a lower row of power generation panels 1 and an upper row of power generation panels 2. The difference from Example 1 is that each row of power generation panels includes three solar panels 3, which are aligned and symmetrically arranged up and down, and the whole constitutes a double-row six-piece solar folding panel, and its protection plate 4 is located on one side of the upper row of power generation panels 2. The other structures of the power generation panels are basically the same as those in Example 1, and can also be folded together. Due to the different number of solar panels, the rated power generation of the two is different.

[0037] In this example, two sets of bracket assemblies are arranged on the back of the lower row of power generation panels 1, and each set of bracket assemblies includes a first support plate 61, a second support plate 62, and a first webbing 63. The structure is the same as that of Example 1 and will not be repeated; the difference from Example 1 is that the bracket assembly in this example also includes a second webbing 64 and a third webbing 65. The second webbing 64 is located between the first support plate 61 and the back of the lower row of power generation panels 1. The lower end of the second webbing 64 is fixedly connected to the lower end of the first support plate 61, and the upper end of the second webbing 64 is fixedly connected to the upper end of the first webbing 61. The two ends of the third webbing 65 are respectively fixedly connected to the middle of the first webbing 63 and the second webbing 64. Through the mutual connection and arrangement of the three webbings, a plurality of triangular structures are formed between the first support plate and the lower row of power generation panels in this example, making the support structure more stable.

[0038] The above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced or recombined by equivalent means. These modifications, replacements or combinations do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various implementation modes of the present application, and should all be included in the protection scope of the present application.
