Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

Fig. 1 shows a schematic view of a solar module according to the present invention. As shown in fig. 1, the solar cell module of the present invention includes a frame 1 and a solar cell 2 disposed in the frame 1.

Wherein the frame 1 is used for protecting the solar cell 2. In actual use, solar energy is absorbed by the solar cell 2.

In the present invention, preferably, the solar cell 2 is formed by connecting a plurality of solar cell sub-sheets in series. In this way, adjustment is facilitated.

As shown in fig. 2, in the present invention, the frame 1 is a detachable frame, which includes an upper frame 1.1, a lower frame 1.3, and two connecting columns 1.2 connecting the upper frame 1.1 and the lower frame 1.3.

Thus, a frame can be adapted to solar modules of different sizes and powers, so that the solar modules are variable and can be adjusted as required. For example, when the power requirement is larger, more solar cell sub-sheets can be connected in series, for example, so that the solar cell 2 is 52 solar cell sheets connected in series, and the frame is composed of the upper frame 1.1, the lower frame 1.3 and two connecting columns 1.2 connecting the upper frame 1.1 and the lower frame 1.3. When less power is needed, fewer solar cell sub-pieces can be connected in series, for example, so that the solar cell 2 is 36 solar cell pieces connected in series, and the frame is composed of the upper frame 1.1 and the lower frame 1.3. Thus, it is more flexible.

In the present invention, preferably, the lower ends of the two vertical sides of the upper frame 1.1 are provided with first internal thread holes 1.1.1. The upper ends of two vertical edges of the lower frame 1.3 are provided with second screws 1.3.1. The upper ends of the two connecting columns 1.2 are provided with first screw rods 1.2.1, and the lower ends of the two connecting columns are provided with second internal thread holes 1.2.2. Thus, when a larger frame needs to be built, the first internal threaded hole 1.1.1 is matched with the first screw rod 1.2.1, and the second screw rod 1.3.1 is matched with the second internal threaded hole 1.2.2, so that a large frame consisting of the upper frame 1.1, the lower frame 1.3 and the connecting column 1.2 can be formed. When a smaller frame needs to be built, the first internal thread hole 1.1.1 is matched with the second screw rod 1.3.1, and then the small frame consisting of the upper frame 1.1 and the lower frame 1.3 can be formed.

As shown in fig. 3, in the present invention, the cross section of the frame 1 includes a horizontal bottom plate 11. And a first vertical plate 12 and a second vertical plate 13 which are arranged in parallel are arranged on the horizontal bottom plate 11. Wherein the height of the second vertical plate 13 is greater than the height of the first vertical plate 12.

A first horizontal plate 14 is arranged at the top of the first vertical plate 12, and one end of the first horizontal plate 14 is connected with the second vertical plate 13. The top of the second vertical plate 13 is provided with a second horizontal plate 15, and one end of the second horizontal plate 15 is connected with the second vertical plate 13. In this way, a solar cell accommodating groove 16 is formed between the portion of the second vertical plate 13 between the first horizontal plate 14 and the second horizontal plate 15, and the first horizontal plate 14 and the second horizontal plate 15. When the solar cell 2 is mounted in the frame 1, the periphery of the solar cell 2 is inserted into the solar cell receiving groove 16.

Furthermore, in the present invention, a baffle 17 extending downward is provided in the middle of the lower plane of the second horizontal plate 15.

In this way, as shown in fig. 4, before the solar cell 2 is inserted into the solar cell accommodating groove 16, the silicon gel or the foam rubber 3 is filled into the solar cell accommodating groove 16, and the silicon gel or the foam rubber 3 is made to be closer to the second vertical plate 13.

As shown in fig. 5, when the solar cell 2 is inserted into the solar cell accommodating groove 16, the solar cell 2 pushes the baffle 17, so that the baffle 17 moves towards the second vertical plate 13, and thus, under the blocking of the baffle 17, the silicone or foam 3 does not overflow onto the upper surface of the solar cell 2, but only onto the lower surface of the solar cell 2, and finally remains on the horizontal bottom plate 11, without affecting the upper surface absorbing solar energy, and therefore, secondary processing, such as cutting or rubbing of excess silicone or foam on the upper surface, is not required, thereby saving time, improving efficiency, and improving the yield of solar cell modules.

In the present invention, the baffle 17 may be a thin sheet, so that the baffle 17 can be broken towards the second vertical plate 13 under the pushing of the solar cell 2.

Of course, the baffle 17 can also be mounted on the second horizontal plane 15 through a rotating shaft or the like, so that the baffle 17 can rotate towards the second vertical plate 13 under the pushing of the solar cell 2.

The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
