[0028] To further illustrate each embodiment, the present utility model provides accompanying drawings. These drawings are a part of the disclosure of the present utility model, which are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operation principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] In the description of the present invention, the orientation or positional relationships such as "upper", "lower", "left", "right", "front", "rear", etc. are based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0030] Now, the present utility model will be further described in combination with the accompanying drawings and the detailed implementation manners.

[0031] Refer to Figures 1 to 7 As shown, a photovoltaic border assembly 100 provided in this embodiment includes a plurality of borders 10 and a plurality of connecting corner codes 20; the plurality of borders 10 are spliced end to end to form a frame, and the connecting corner codes 20 are connected between two adjacent borders 10; specifically, in this embodiment, the number of both the borders 10 and the connecting corner codes 20 is four. The four borders 10 are spliced end to end to form a quadrilateral frame.

[0032] Define the side of the border 10 facing the center of the frame as the inner side; wherein, the border 10 has an insertion opening 11 extending along its length direction, a mounting opening 12 located above the insertion opening 11 and having an inner opening, and a reinforcing plate 13 formed on the inner side and extending inward; the connecting corner code 20 is fixedly inserted into the insertion openings 11 of two adjacent borders 10, and the reinforcing plate 13 is a bending structure with undulations; thus configured, the strength of the photovoltaic border assembly 100 is greatly enhanced; and the supportability is better.

[0033] The reinforcing plate 13 has a convex portion 14 and a concave portion 15 extending along its length direction, and the convex portion 14 and the concave portion 15 are arranged alternately to form a undulating bending structure; thus, reinforcement can be carried out in its length direction. Specifically, in this embodiment, the reinforcing plate 13 is a serrated bending structure with undulations, which is easy to process and form, such as can be directly formed by stamping or other means. Of course, in other embodiments, the serrated bending structure can also be replaced with a sine wave-shaped bending structure or the like.

[0034] Specifically, in this embodiment, two of the side walls 111 forming the insertion opening 11 are also undulating bending structures, which further play a reinforcing role. Of course, in other embodiments, all four side walls 111 forming the insertion opening 11 can be undulating bending structures, or several of the four side walls 111 can be undulating bending structures; or they can all be straight walls, etc.

[0035] Further, in this embodiment, the side wall 121 of the frame 10 forming the installation opening 12 and the reinforcing plate 13 are of a double-layer structure. For example, in this embodiment, the frame 10 is obtained by bending a metal plate; specifically, it is obtained by folding a metal plate in half and then bending it, so that the side wall 121 of the installation opening 12 and the reinforcing plate 13 are of a double-layer structure, while the insertion opening 11 is of a single-layer structure, and each metal plate constitutes two of the side walls 111 of the insertion opening 11 respectively. That is, during preparation, a metal plate is first folded in half to form a double-layer structure, and then bent to obtain the above-mentioned frame structure. The end of the side wall 121 forming the installation opening 12 is a folded closed end 122 of the double-layer structure; the sharp edge of the side wall 121 of the installation opening 12 is eliminated to ensure operation safety. The folded open end of the double-layer structure is located at the end 133 of the reinforcing plate 13. Specifically, the first side plate 131 of the folded open end of the double-layer structure bypasses the end of the second side plate 132 and folds to the other side of the second side plate 132, which also eliminates the sharp edge and ensures operation safety.

[0036] The end of the upper side wall forming the installation opening 12 is bent downward to form an elastic pressing portion 123 inclined downward; this installation opening 12 is used to install a photovoltaic laminate, and the setting of the elastic pressing portion 123 can press the photovoltaic laminate tighter and make the assembly more reliable.

[0037] Further, the connecting corner code 20 includes two connecting arms 21 arranged perpendicularly; the two connecting arms 21 of the connecting corner code 20 are respectively fixedly inserted into the insertion ports 11 of two adjacent side frames 12, so as to realize the fixation of two adjacent side frames 10. Further, barbs 22 are arranged on both connecting arms 21 of the connecting corner code 20, and a limiting step 112 abutted against the barb 22 is arranged on the side wall 111 of the insertion port 11. After insertion, through the abutting cooperation between the limiting step 112 and the barb 22, the assembly is more firm and not easy to disengage. More specifically, for better assembly, in this embodiment, the limiting step 112 is obtained by stamping the side wall 111 of the insertion port 11; for example, after the connecting arm 21 of the connecting corner code 20 is inserted into the insertion port 11, the limiting step 112 is prepared by stamping. Of course, in other embodiments, the fixed connection structure between the connecting corner code 20 and the side frame 10 is not limited to this, and can also be strengthened by means such as riveting.

[0038] Further, referring to Figure 6 as shown, the end faces at both ends of the side frame 10 are inclined end faces 16. In this embodiment, the inclined end faces 16 are inclined 45° relative to the length direction of the side frame 10, and the tips of the inclined end faces 16 are bent inward to form a bent section 17; the ends of two adjacent side frames 10 are spliced so that the inclined end faces 16 of the two side frames 10 are attached to each other, and the bent sections 17 of the two side frames 10 are abutted against each other to form an arc transition surface, as Figure 7 shown; thereby making the end corners of the frame-shaped frame present an arc transition. In this way, the tips at the end corner positions of the frame-shaped frame can be eliminated, and it is not easy to cut the hands of personnel and other positions.

[0039] Although the present invention is specifically shown and described in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them are within the protection scope of the present invention.
