Referring to fig. 1, 2 and 6, one embodiment of the present application provides a frame member 10. The frame part 10 comprises a carrier 101, a first stop 102, a second stop 103 and a cover 104. The carrier 101 has a carrier surface 1011. The first limiting members 102 and the second limiting members 103 are alternately arranged and protrude from the bearing surface 1011. The cover 104 protrudes from the second stopper 103. The second limiting member 103, the cover 104 and the bearing surface 1011 enclose a first receiving groove 105 for receiving an edge of the solar cell 20. The distance between the cover 104 and the bearing surface 1011 is greater than or equal to the height of the first limiting member 102 protruding from the bearing surface 1011.

In the frame component 10 of the present embodiment, the distance between the cover 104 and the bearing surface 1011 is greater than or equal to the height of the first limiting member 102 protruding from the bearing surface 1011, when the solar cell 20 is mounted, the edge of the solar cell 20 is located in the first accommodating groove 105, and the first limiting member 102 may be lower than the surface of the solar cell 20, or the first limiting member 102 is flush with the surface of the solar cell 20. At this time, there is a certain height difference between the cover 104 and the first stopper 102, and the space formed by the height difference can be used as a drainage space on the surface of the solar cell 20, so that water is polluted to drain out of the solar cell 20, the problem of water accumulation and pollution accumulation at the edge of the solar cell 20 is improved, the area of the solar cell 20 covered is reduced, and the improvement of the power generation capacity of the solar cell 20 is promoted.

It will be appreciated that the positions of the sides of the solar cell 20 can be defined and the sides of the solar cell 20 can be well protected by the arrangement of the first and second stoppers 102 and 103. Meanwhile, the second limiting piece 103, the covering piece 104 and the first accommodating groove 105 formed by the bearing surface 1011 can accommodate the edge of the battery, and the covering piece 104 can cover part of the surface of the edge of the solar battery 20 to improve the installation stability of the solar battery 20 and reduce the risk of frame detachment of the solar battery 20.

In some embodiments, the surface of the first stop 102 facing the solar cell 20 and the surface of the second stop 103 facing the solar cell 20 are flush. In this way, the contact surface between the solar cell 20 and the first limiting member 102 and the second limiting member 103 is smoother, and the stability between the solar cell 20 and the frame member 10 is improved.

In some embodiments, the surface of the first limiting member 102 facing away from the solar cell 20 and the surface of the second limiting member 103 facing away from the solar cell 20 are flush, so that the outer side surface of the frame member 10 can be smoother.

Referring to fig. 3 to 5, in some embodiments, there are a plurality of first limiting members 102, a plurality of first limiting members 102 are disposed at intervals, and a second limiting member 103 is disposed between adjacent first limiting members 102. It is understood that the number of the cover members 104 is equal to the number of the second stopper members 103. At this time, different positions of the edge of the solar cell 20 can be covered by the plurality of covering pieces 104, which is favorable for improving the stability of the installation between the solar cell 20 and the frame member 10 and further reducing the risk of frame detachment of the solar cell 20. Meanwhile, the first limiting members 102 are arranged at intervals, so that a plurality of drainage spaces can be formed, and better drainage and dirt removal effects are achieved.

In some embodiments, the first stop 102 is one more than the second stop 103. I.e. a second stop 103 is arranged between two adjacent first stops 102. By arranging the first limiting pieces 102 and the second limiting pieces 103 with proper number relation, better drainage and dirt discharging effects and lower frame removing risks can be better considered.

Alternatively, in the embodiment shown in fig. 3 to 5, there are four first stoppers 102 and three second stoppers 103. The first stoppers 102 and the second stoppers 103 are alternately arranged. It is understood that the number of the first stoppers 102 and the second stoppers 103 may be appropriately selected according to the size of the solar cell 20. For example, there may be two first stoppers 102 and one corresponding second stopper 103. For another example, there may be three first stoppers 102 and two corresponding second stoppers 103. For another example, the first limiting members 102 may have five, and the corresponding second limiting members 103 may have four.

Referring again to fig. 6, in some embodiments, a glue groove 1041 is provided on the cover 104. The notch of the glue groove 1041 faces the first receiving groove 105. An adhesive (not shown) may be provided in the adhesive groove 1041, by which the connection between the solar cell 20 and the frame member 10 is more stable. Alternatively, the glue groove 1041 may be filled with silica gel to obtain an adhesive member.

Referring to fig. 9 and 11, in some embodiments, a buffer 40 may be provided at an end of the cover 104 facing the first receiving groove 105. The buffer member 40 can buffer the acting force between the solar cell 20 and the frame member 10, so that the risk of damage to the solar cell 20 caused by the frame member 10 is reduced. Alternatively, the buffer 40 may be a glue strip. Further alternatively, the cushion 40 may be an Ethylene Propylene Diene Monomer (EPDM) cushion.

Referring to fig. 2 to 6, in some embodiments, the carrier 101 has a second accommodating groove 1012, where a groove wall of the second accommodating groove 1012 and the bearing surface 1011 are located on the same side of the first limiting member 102, and a groove opening direction of the second accommodating groove 1012 is opposite to a groove opening direction of the first accommodating groove 105. The provision of the second receiving groove 1012 reduces the weight of the carrier 101 and thus the weight and cost of the frame part 10. It will be appreciated that the slot wall of the second receiving slot 1012 is further away from the first stop 102 than the bearing surface 1011.

Referring to fig. 2 and 6, in some embodiments, the frame member 10 further includes a reinforcement member 106, and the reinforcement member 106 extends from an end of the second stop member 103 remote from the cover 104 and into the second receiving groove 1012. By the provision of the reinforcement 106, the connection between the second stopper 103 and the carrier 101 can be made more secure. When the solar cell 20 is subjected to a load perpendicular to the surface thereof, the movement of the reinforcement member 106 is limited by the second accommodating groove 1012, so that the position of the second limiting member 103 can be better fixed, and the risk of frame detachment of the solar cell 20 is further reduced.

In some embodiments, the reinforcement 106 has a first cavity 1061. The provision of first cavity 1061 may reduce the weight of stiffener 106, further reducing the weight and cost of frame member 10.

In some embodiments, the height of the stiffener 106 is less than or equal to the channel width of the second receiving channel 1012. Referring to FIGS. 5 and 6, the reinforcement 106 has a height L1, and the second receiving groove 1012 has a groove width L3, wherein L1 is less than or equal to L3. The reinforcement 106 can then be better fitted with the second receiving slot 1012, which is advantageous for more stable definition of the position of the reinforcement 106.

Further, the width of the reinforcement 106 is less than or equal to the groove depth of the second receiving groove 1012. Referring to FIGS. 5 and 6, the stiffener 106 has a width L2 and the second receiving groove 1012 has a groove depth L4, wherein L2 is less than or equal to L4. At this time, the reinforcement 106 and the carrier 101 can be further more firmly fitted.

Alternatively, the cover 104 and the second stopper 103 are integrally formed. Alternatively, the reinforcement member 106 and the second stopper 103 are integrally formed.

The stability of the position between the reinforcement 106 and the carrier 101 can be further improved by the provision of the support 107.

In some embodiments, the support 107 has a second cavity 1071. The provision of the second cavity 1071 may reduce the weight of the support member 107, further reducing the weight and cost of the frame member 10
