Utility Model Content

[0006] The solar panel as a whole is composed of a shell, a back plate, a silicon wafer, a lead, a diode body, a glass panel and a junction box;

[0007] A rotating shaft is fixed on the surface of the connecting plate, and a first adjusting plate and a second adjusting plate are arranged on the left and right sides of the connecting plates.

[0016] 1. The utility model can realize the bypass function by connecting each silicon chip in parallel with a diode body. When a silicon chip generates reverse current due to shielding or failure, the corresponding diode body is turned on to prevent the reverse voltage on the silicon chip from accumulating, thereby protecting the entire battery string from the hot spot effect and extending the life of the component. The built-in diode body reduces the exposed wiring points, reduces the risk of failure caused by wiring errors or corrosion, enhances the environmental adaptability and long-term stability of the component, and does not require additional addition or replacement of diodes at the installation site, simplifies the installation process, and reduces maintenance requirements. This design optimizes the performance, reliability and maintenance convenience of solar modules, especially in solar energy systems with refined management and high efficiency requirements.

[0017] 2. When the solar panel needs to be stored and folded as a whole, the hydraulic rod is started to push the first slide bar to move downward. At this time, the first slide bar will drive the linkage plates on both sides to move and rotate, so that the connecting plates on both sides can begin to flip inward in a V shape. During this period, multiple linkage plates will also drive the second slide bar to slide upward inside the second slide groove together, so that the multiple solar panels as a whole can finally be folded together, thereby reducing the space occupied by the overall device, avoiding dust accumulation and damage caused by accidental collision, and extending the service life. At the same time, the vertical placement of multiple solar panels after being folded as a whole reduces the chance of hail directly hitting a large area of ​​plane in ice and snow weather. When hail falls vertically on the solar panel, the angle of contact with the panel surface is almost 90 degrees. Such an impact angle helps the hail to bounce off after hitting the panel, reducing the penetration and potential damage to the panel material, reducing the possibility of local damage, and in the vertical state, hail is not easy to accumulate on the overall panel of the solar panel, avoiding structural pressure and potential rupture risks caused by increased weight of ice and snow.

[0027] See also Figure 1-Figure 8 , a built-in diode solar module, comprising a solar panel as a whole 1, and connecting plates 2 are arranged on both sides of the solar panel as a whole 1;

[0028] The solar panel 1 can receive sunlight and generate electricity, and the connecting plate 2 is used to connect a plurality of solar panel 1 .

[0029] The solar panel as a whole 1 is composed of a shell 101, a back plate 102, a silicon chip 103, a lead 104, a diode body 105, a glass panel 106 and a junction box 107. The back plate 102 is fixed to the inner wall of the shell 101, the silicon chip 103 is bonded to the surface of the back plate 102 through an EVA adhesive film, the lead 104 is installed on the surface of the back plate 102 and is bonded and fixed through the EVA adhesive film, one end of the lead 104 passes through the back plate 102 and is connected to the junction box 107, each silicon chip 103 is connected in parallel with the diode body 105 through the lead 104, the diode body 105 uses a Schottky diode, the glass panel 106 is located above the back plate 102, and the glass panel 106 is fixedly connected to the inner wall of the shell 101;

[0030] By connecting each silicon chip 103 in parallel with a diode body 105, a bypass function can be achieved. When a silicon chip 103 generates reverse current due to obstruction or failure, the corresponding diode body 105 is turned on to prevent the reverse voltage on the silicon chip 103 from accumulating, thereby protecting the entire battery string from the hot spot effect and extending the life of the component. The built-in diode body 105 reduces the exposed wiring points and reduces the risk of failure caused by wiring errors or corrosion, thereby enhancing the environmental adaptability and long-term stability of the component. There is no need to add or replace additional diodes at the installation site, which simplifies the installation process and reduces maintenance requirements. This design optimizes the performance, reliability and ease of maintenance of solar modules, especially in solar systems with refined management and high efficiency requirements.

[0031] The connecting plate 2 is fixed to the left and right sides of the surface of the shell 101, and the number of the solar panels 1 as a whole is four. The connecting plate 2 surface is fixed with a rotating shaft 3. The left and right sides of the multiple connecting plates 2 are provided with a first adjustment plate 4 and a second adjustment plate 9. The rotating shafts 3 on the surfaces of the multiple connecting plates 2 are rotatably connected to the surfaces of the first adjustment plates 4. The connecting plate 2 surface is rotatably connected with a linkage plate 7. The first adjustment plate 4 surface is provided with a first slide groove 5. The first slide groove 5 surface is slidably connected with a first slide bar 6. The multiple linkage plates 7 are hinged to the surfaces of the first slide bar 6. The first adjustment plate 4 surface is fixed with a hydraulic rod 8. One end of the hydraulic rod 8 is fixedly connected to the surface of the first slide bar 6. The rotating shafts 3 on the surfaces of the multiple connecting plates 2 are rotatably connected to the surfaces of the second adjustment plates 9. The second adjustment plate 9 surface is provided with a second slide groove 10. The second slide groove 10 surface is slidably connected with a second slide bar 11. The surfaces of the multiple linkage plates 7 are hinged to the surfaces of the second slide bar 11. The second adjustment plate 9 surface is fixed with a bracket 12;

[0032] When the solar panel 1 needs to be stored and folded, the hydraulic rod 8 is started to push the first slide bar 6 to move downward. At this time, the first slide bar 6 will drive the linkage plates 7 on both sides to move and rotate, so that the connecting plates 2 on both sides can begin to flip inward in a V shape. During this period, multiple linkage plates 7 will also drive the second slide bar 11 to slide upward inside the second slide groove 10, so that the multiple solar panels 1 can finally be folded together, thereby reducing the space occupied by the entire device, avoiding dust accumulation and damage caused by accidental collisions, and extending the service life. At the same time, the vertical placement of multiple solar panels 1 after folding reduces the chance of hail directly hitting a large area of ​​flat surface in ice and snow weather. When hail falls vertically on the solar panel, the angle of contact with the panel surface is almost 90 degrees. Such an impact angle helps the hail to bounce off after hitting the panel, reducing the penetration and potential damage to the panel material, reducing the possibility of local damage, and in the vertical state, hail is not easy to accumulate on the panel of the solar panel 1 as a whole, avoiding structural pressure and potential rupture risks caused by the increase in ice and snow weight.

[0033] Furthermore, a connecting rod 16 is fixed between the plurality of first adjustment plates 4, and a fixing plate 17 is fixed on the top of the connecting rod 16;

[0034] The multiple fixing plates 17 can protect the top gap of the folded solar panel 1 to prevent falling hail or other impurities from falling directly into the gaps between the multiple solar panels 1, thereby further improving the protection effect of the solar panel 1.

[0035] Furthermore, a plurality of compression springs 18 are fixed on the top of the fixing plate 17, and a buffer plate 19 is fixed on the top of the compression spring 18;

[0036] When hail or other impurities fall onto the surface of the buffer plate 19, the compression spring 18 can be compressed to buffer part of the impact force generated when the object falls, so that the protective effect of the fixed plate 17 is better, and the service life of the fixed plate 17 is increased, preventing the fixed plate 17 from being quickly damaged by hard collisions.

[0037] Furthermore, a protective plate 13 is fixed on the surface of the connecting plate 2, and the surface of the protective plate 13 is inclined;

[0038] The protective plate 13 can protect the upper part of the two outermost solar panels 1 after folding, so that vertically falling hail or other impurities are not easy to fall directly onto the surface of the solar panel 1.

[0039] Furthermore, a water tank 15 is fixed on the surface of the bracket 12, a liquid filling port is provided on the top of the water tank 15, and a drain valve is connected to the surface of the water tank 15;

[0040] After the water tank 15 is filled with water through the liquid filling port, the overall center of gravity of the bracket 12 can be lowered, so that the bracket 12 has better stability, so that after the multiple solar panels 1 are unfolded as a whole, the bracket 12 will not fall over.

[0041] Furthermore, a buffer strip 14 is fixed on the surface of the connecting plate 2, and the buffer strip 14 is made of rubber;

[0042] The plurality of buffer strips 14 can play a buffering role, so that when the plurality of solar panels 1 drive the connecting plates 2 to fold and merge, the buffer strips 14 can prevent the plurality of connecting plates 2 from having a hard contact with each other, thereby preventing the plurality of connecting plates 2 from being damaged by collision when the plurality of solar panels 1 are folded.

[0043] Furthermore, the bracket 12, the second adjustment plate 9, the connecting plate 2 and the first adjustment plate 4 are all made of aluminum alloy;

[0044] The aluminum alloy material has the advantages of high strength and light weight. It can well reduce the overall weight of the device and is not prone to corrosion damage.

[0045] Furthermore, a telescopic rod 20 is fixed to the top of the fixed plate 17, and the top of the telescopic rod 20 is fixedly connected to the bottom of the buffer plate 19;

[0046] The telescopic rod 20 can guide and limit the buffer plate 19 so that the buffer plate 19 can only move up and down when impacted, thereby preventing the buffer plate 19 from causing the compression spring 18 to bend.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
