Description

Technical Field

[0001] This utility model relates to the field of steel frame technology, specifically a mortise and tenon steel frame for photovoltaic modules. Background Technology

[0002] Energy conservation and emission reduction have become increasingly important. Traditional photovoltaic module frames are made of aluminum alloy. However, the electrolysis of aluminum in the production process is a high-energy-consuming step, requiring approximately 13,500 kWh of electricity to electrolyze one ton of aluminum, while producing one ton of steel requires only 4,500 kWh. Therefore, steel consumes only one-third the energy of aluminum alloy, and its carbon emissions are far lower. The continuously rising price of aluminum has increased the cost of aluminum alloy frames, while the price increase of steel has lagged behind that of aluminum. Against this backdrop, steel frames for photovoltaic modules with zinc-aluminum-magnesium coatings have emerged.

[0003] In existing photovoltaic module steel frames, the connection between the steel frame and the corner bracket mainly relies on the friction between the teeth on the corner bracket and the steel frame. This frictional force results in poor connection stability and makes it impossible to reconnect the frame if the corner bracket is lost, affecting the performance. Therefore, a mortise and tenon type steel frame for photovoltaic modules is proposed. Utility Model Content

When connecting the long frame body and the short frame body, the clamping plate is inserted into the clamping groove, and at the same time, the clamping plate of the long frame body is clamped on the short frame body to realize the mortise and tenon connection. During the insertion process, the deformation spring rod bends towards the deformation reserved gap. After insertion, the deformation spring rod rebounds, so that the limiting protrusion is fitted into the limiting groove. The connection can be completed without corner brackets, avoiding loosening of the connection and improving the connection stability.

When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] This utility model provides a mortise and tenon steel frame for photovoltaic modules. When connecting the long frame body and the short frame body, a clamping plate is inserted into a clamping groove, while the clamping plate of the long frame body holds the short frame body, achieving a mortise and tenon connection. During insertion, a deformation spring bends towards the pre-reserved deformation slot. After insertion, the deformation spring rebounds, causing the limiting protrusion to engage with the limiting groove. This eliminates the need for corner brackets, preventing loosening and improving connection stability. Please refer to [link / reference]. Figures 1-6 This includes: a long border of 100 and a short border of 200.

[0032] The long frame 100 includes a long frame body 110, a clamping plate 120, a deformation reserved gap 130, a deformation elastic rod 140, and a limiting protrusion 150. The long frame body 110 is provided with clamping plates 120 at the top and bottom of its ends. Deformation reserved gaps 130 are provided on the clamping plates 120. One side of the deformation reserved gap 130 is a deformation elastic rod 140. A limiting protrusion 150 is provided at the outer end of the deformation elastic rod 140.

[0033] The long frame body 110 is symmetrically arranged at both ends, as shown in the figure. Figure 6 As shown, the long-bordered main body 110 also includes eight types (101 to 108) as shown in the figure, which can be selected and used according to needs.

[0034] The short frame 200 is connected to the long frame body 110. The short frame 200 includes a short frame body 210, a clamping groove 220 and a limiting groove 230. The top end of the short frame body 210 is provided with a clamping groove 220. The clamping groove 220 is fitted into the clamping plate 120. The side of the clamping groove 220 is provided with a limiting groove 230 corresponding to the limiting protrusion 150.

[0035] The short frame body 210 is symmetrically arranged on the left and right sides. The long frame body 110 has the same central cross-sectional shape as the short frame body 210. The depth of the clamping groove 220 is less than the thickness of the short frame body 210. The clamping plate 120 is fitted into the clamping groove 220, so that the clamping plate 120 can be clamped in the clamping groove 220 of the short frame body 210 while being inserted.

[0036] The long frame body 110 and the short frame body 210 have beveled edges that fit together at a 45-degree angle, forming a right-angled frame when connected.

[0037] The long frame body 110 has a slot 160 at the center of its end, and a downward slope 170 is provided on the inner side of the slot 160. The short frame body 210 has an insert plate 240 at the center of its end, and an upward slope 250 is provided at the end of the insert plate 240. When the insert plate 240 is connected to the slot 160, the end of the insert plate 240 is lifted up by the squeezing action of the upward slope 250 and the downward slope 170. The photovoltaic panel is installed on the upper side of the frame and is clamped to the photovoltaic panel by the lifted end of the insert plate 240, which improves the connection stability.

[0038] Since the limiting protrusion 150 needs to be inserted and removed, the limiting protrusion 150 is a semi-circular block, and the limiting groove 230 is a semi-circular groove that fits into the limiting protrusion 150. The circular arc edge facilitates the use of the insertion plate.

[0039] A sealing gasket is provided on the inner side of the long frame body 110 and the short frame body 210. The sealing gasket is made of rubber and protects the photovoltaic panel.

[0040] In practical use, when connecting the long frame body 110 and the short frame body 210, the clamping plate 120 is inserted into the clamping groove 220, and at the same time, the clamping plate 120 of the long frame body 110 is clamped into the clamping groove 220 of the short frame body 210 to achieve a mortise and tenon connection. During the insertion process, the deformation spring rod 140 bends towards the deformation reserved gap 130. After insertion, the deformation spring rod 140 rebounds, so that the limiting protrusion 150 is fitted into the limiting groove 230. The connection can be achieved without corner brackets, avoiding loosening of the connection and improving connection stability. After the connection, the insert plate 240 is connected to the slot 160. The end of the insert plate 240 is raised by the squeezing action of the upper slope 250 and the lower slope 170. The photovoltaic panel is installed on the upper side of the frame, and is clamped on the photovoltaic panel by the raised end of the insert plate 240, which improves connection stability.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
