Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module frame technology, and in particular to a novel steel angle bracket for photovoltaic frames. Background Technology

[0002] The four corners of the photovoltaic frame need to be spliced ​​and fixed with corner brackets. The corner brackets used for the steel frame are generally made of galvanized aluminum-magnesium steel through continuous stamping to form an integrated structure. Before the photovoltaic module is assembled, the corner brackets are usually installed on both ends of the short frame and fixed by matching the width and height of the corner brackets and setting the rivets. In traditional technology, the upper and lower plates of the corner brackets are fixed by using convex bulges or punches to match the punches or convex bulges at the corresponding positions of the frame.

[0003] The combination of the convex hull and the punching hole causes the corner code to be deformed to a large extent when it is inserted into the frame. Furthermore, when advancing vertically, the success rate of the convex hull aligning with the hole is low due to the horizontally unlimited positioning structure. Utility Model Content

[0004] The purpose of this invention is to provide a new type of steel angle bracket for photovoltaic frames to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a brand-new steel corner bracket for photovoltaic frame, including frame and corner bracket. The corner bracket is integrally formed by sheet metal stamping of zinc-aluminum-magnesium steel strip or stainless steel with a thickness of 0.6-1.2mm. The corner bracket consists of two mutually perpendicular fixed ends. The frame and corner bracket cooperate with each other to limit and fix the photovoltaic module. The frame is cold-formed from zinc-aluminum-magnesium steel strip or stainless steel, and a frame cavity is provided in the middle of the frame. The fixed end includes an upper plate, an outer plate, a lower plate, and a guide plate. The upper plate and the lower plate are perpendicular to the outer plate and are used to support the vertical and horizontal positions of the corner bracket within the frame cavity. The lower plate has at least one lower convex bulge in the middle, which is used to fix the longitudinal position of the corner bracket after it is inserted into the frame. The upper plate has at least one upper convex bulge in the middle.

[0006] Preferably, the frame has a slot at the end position, and the upper convex bulge is formed by stamping an upper flat plate from the inside out. When the frame and the corner bracket are inserted into each other, the upper convex bulge is inserted into the slot.

[0007] Preferably, the slot is an open type, that is, the slot starts from the cut surface of the frame and extends inward.

[0008] Preferably, the height of the upper convex bulge is less than one times the material thickness, its total length is 2-20mm, its tail width is 2-5mm, and its head width is less than its tail width. When the frame and corner bracket are installed together, the upper convex bulge can be easily inserted into the preset slot.

[0009] Preferably, the lower convex bulge is formed by stamping a lower flat plate from the inside out, and the frame has the same number of locking holes as the lower convex bulge in the middle. When the frame and the corner bracket are installed together, the lower convex bulge and the locking holes are engaged with each other.

[0010] Preferably, the ends of the upper plate, lower plate, and outer plate are all provided with guide plates, which extend 2-10mm from the edge and bend inward to facilitate the insertion of corner brackets into the frame.

[0011] Preferably, both fixed ends of the corner bracket are provided with self-mortise joints and are connected and fixed through the self-mortise joints. The self-mortise joints are located near the ends of the upper and lower plates.

[0012] Preferably, the mortise is formed by rivetless riveting or by interference fit stamping of protrusions and punches.

[0013] The beneficial effects of this utility model are as follows: the upper plate of the corner code is provided with an upper convex bulge at the root, and the upper plate of the frame cavity is provided with a slot of corresponding size. The cooperation between the upper convex bulge and the slot will greatly reduce the corner code deformation problem, and increase the lateral limit during the longitudinal advancement process, which greatly reduces the problem of low success rate of convex bulge to hole in traditional technology.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] See Figures 1-4This utility model provides a novel steel angle bracket for photovoltaic frames, comprising a frame 1 and an angle bracket 2. The angle bracket 2 is characterized by being integrally formed from a 0.6-1.2mm thick zinc-aluminum-magnesium steel strip or stainless steel by sheet metal stamping. The angle bracket 2 consists of two mutually perpendicular fixed ends 21. The frame 1 and the angle bracket 2 cooperate to limit and fix the photovoltaic module. The frame 1 is formed by cold bending of zinc-aluminum-magnesium steel strip or stainless steel, and the frame 1 has a frame cavity in the middle; the fixed end 21 includes an upper plate 211, an outer plate 212, a lower plate 213 and a guide plate 214. The upper plate 211 and the lower plate 213 are perpendicular to the outer plate 212 and are used to support the vertical and horizontal position of the corner bracket 2 in the frame cavity; it can accurately limit and fix the photovoltaic module from multiple directions to ensure that the photovoltaic module is accurately positioned in the frame, avoid the impact of photovoltaic module displacement on power generation efficiency, and also facilitate the overall layout and installation of the photovoltaic system.

[0021] The lower plate 213 has at least one lower protrusion 2121 in the middle for fixing the longitudinal position of the corner bracket 2 after it is inserted into the frame 1. The upper plate 211 has at least one upper protrusion 2111 in the middle. The frame 1 has a slot 102 at its end. The upper protrusion 2111 is formed by stamping the upper plate 211 from the inside out. When the frame 1 and the corner bracket 2 are inserted into each other, the upper protrusion 2111 is inserted into the slot 102. The slot 102 is open, that is, the slot 102 starts from the cut surface of the frame and extends inward. The installation process is simpler and faster, without the need for additional complex operations and tools, which greatly improves the installation efficiency, reduces the installation difficulty and labor costs. The cooperation between the upper protrusion 2111 and the slot 102 will greatly reduce the corner bracket deformation problem and add lateral limit during longitudinal advancement, which greatly reduces the problem of low success rate of protrusion hole alignment in traditional technology. At the same time, when installing the corner bracket 2, it can cooperate with the upper protrusion 2111 of the corner bracket 2 to restrict the rotation of the corner bracket 2 in the frame cavity. The height of the upper convex bulge 2111 is less than one times the material thickness, its total length is 2-20mm, its tail width is 2-5mm, and its head width is smaller than its tail width. When the frame 1 and the corner bracket 2 are installed together, the upper convex bulge 2111 can easily fit into the preset slot 102. The specific size and shape design makes the upper convex bulge 2111 fit into the slot 102 more smoothly, ensuring the stability and reliability of the connection.

[0022] The lower convex bulge 2121 is formed by stamping the lower flat plate 213 from the inside out. The frame 1 has the same number of locking holes 101 as the lower convex bulge 2121 in the middle. When the frame 1 and the corner bracket 2 are installed together, the lower convex bulge 2121 and the locking holes 101 engage with each other. This effectively fixes the longitudinal position of the corner bracket 2 within the frame 1, preventing the corner bracket 2 from sliding or shifting in the longitudinal direction, further enhancing the stability of the photovoltaic frame structure and ensuring that the photovoltaic module is fixed in the longitudinal direction.

[0023] The upper plate 211, lower plate 213, and outer plate 212 are all equipped with guide plates 214 at their ends. These guide plates extend 2-10mm from the edge and bend inward to facilitate the insertion of the corner bracket 2 into the frame 1. The guide plates reduce direct collisions and friction between the corner bracket 2 and the edge of the frame 1 during insertion, thereby reducing the risk of damage to the component surface and extending its service life.

[0024] Both fixed ends 21 of the corner bracket 2 are provided with self-mortise joints 215, which are used to connect and fix the bracket. The self-mortise joints 215 are located near the ends of the upper plate 211 and the lower plate 213. The self-mortise joints 215 are formed by rivetless riveting or by interference fit stamping of protrusions and punches. During the production of the corner bracket 2, protrusions and punches are stamped out through a stamping process. When the two fixed ends 21 of the corner bracket 2 are connected, the protrusions and punches interlock, thereby securing the two fixed ends 21. This design allows the corner bracket 2 to be divided into smaller fixed ends 21 during transportation and storage, reducing space occupation, facilitating transportation and storage, and reducing logistics costs. It can also be assembled on-site according to actual needs.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
