Referring to fig. 1-4, the present invention discloses a solar cell module 100, which comprises a frame 1, a solar cell lamination 2 mounted on the frame 1, and a spacer 3 used in cooperation with the frame. In the present invention, the frame 1 may be made of transparent PC (Polycarbonate), PMMA (Polymethyl methacrylate) or other suitable transparent materials, or may be made of general aluminum materials. The cushion block 3 can be made of plastic materials such as PA, ABS and the like or other materials with the characteristics of high strength, high toughness, light weight and the like.

In one embodiment, the frame 1 includes a bottom plate 11, a vertical post 12 extending vertically upward from the bottom plate 11, an open slot 13 disposed at the top of the vertical post 12, and a support slot 14 disposed beside the vertical post 12. The open grooves 13 receive the solar cell lamination members 2, the support grooves 14 receive the spacers 3, and the open direction of the open grooves 13 is opposite to that of the support grooves 14. The cushion blocks 3 received in the supporting grooves 14 provide higher strength to the frame 1 on which the solar cell laminate 2 is mounted. In the present invention, the cushion block 3 is selectively received in the supporting groove 14. In other words, there may be one or more spacers 3; the plurality of spacers 3 may be mounted on the frame 1 entirely, may be mounted on the frame 1 partially, may be mounted on the frame 1 uniformly, or may be mounted selectively in position according to stress.

With reference to fig. 1 and fig. 2, a fastening structure 15 is formed in the supporting groove 14 of the frame 1, and the cushion block 3 is correspondingly provided with a locking structure 31. The snap structure 15 is L-shaped and includes a support plate 151 extending horizontally and a riser 152 extending from an edge of the support plate 151 in a direction perpendicular to the support plate 151. The latch structure 31 includes a connecting arm 311 and a barb 312 formed at the free end of the connecting arm. It will be appreciated that the

catch formations

15 and 31 may be interchanged.

In one embodiment, the cushion block 3 can be detachably mounted in the support groove 14 at other positions of the frame 1 after being fixed in the support groove 14 by detachably locking the locking structure 15 and the locking structure 31 with each other.

In another embodiment, the cushion block 3 fixed in the support groove 14 can be moved from one position to another position in the support groove 14 without disassembly in the support groove 14 by the snap fit between the snap structure 15 and the snap structure 31.

As shown in fig. 2, the pad block 3 has a main body portion 32 having a flat plate shape, a groove 33 is formed in one side surface of the main body portion 32 so as to be recessed inward, and the groove 33 extends in the longitudinal direction of the main body portion 32 and penetrates through the main body portion 32. The locking structures 31 are disposed in the groove 33 and distributed on the groove 33 at the two end openings 330. Referring to fig. 1, the height of the groove 33 on the main body 32 matches the height of the supporting plate 151 in the supporting groove 14. Meanwhile, the height and thickness of the pad block 3 are the same as those of the support groove 14.

In a preferred embodiment, as shown in fig. 1, the column 12 has a closed hollow structure therein. In other embodiments, the column 12 may be a non-enclosed hollow structure or a solid structure; the post 12 may also be provided with an internal recess, which is disposed opposite the support groove 14 and bounded by the post 12. The hollow structure or the inner groove is arranged in the upright post 12, so that the weight of the frame 1 can be reduced, and more toughness or plasticity or fatigue resistance and the like can be provided for the frame 1.

Referring to fig. 3 and 4 in combination with fig. 1, the solar cell module 100 of the present invention further includes an auxiliary support 4 disposed on the back surface of the solar cell laminate 2. The auxiliary support 4 is used to assist in improving the overall stability and reliability of the solar cell module 100, and the number of the auxiliary supports 4 is not limited. It can be understood that, at the intersection position of the auxiliary support 4 and the frame 1, the stress applied to the frame 1 is the largest. Therefore, at the place where the stress is large, the cushion block 3 can be selectively installed so as to significantly increase the strength of the frame 1.

It can be seen that by selectively mounting the cushion block 3 to the frame 1, the strength of the frame 1 is improved, the weight is reduced, the cost is reduced, and the use flexibility is increased. The selectivity here includes not only the number of the cushion blocks but also the positions for mounting the cushion blocks.

The above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention.
