[0025] The structure of the present application is further described below in conjunction with the accompanying drawings.

[0026] The embodiment of the present application provides a composite material frame connection mechanism, wherein the connection mechanism 1 includes a connection angle code 100 and a sleeve structure 200 sleeved with the connection angle code 100.

[0027] like Figure 1 As shown, the connection angle code 100 includes at least two connection arms, and at least one connection arm is provided with a connection tooth 111. In some specific embodiments, the connection angle code 100 includes a first connection arm 110 and a second connection arm 120. The connection angle code 100 of the present application has a first direction X and a second direction Y. The first direction X is perpendicular to the second direction Y. The perpendicularity mentioned in the present application can be an absolute perpendicularity or an approximately perpendicularity. The first connection arm 110 and the second connection arm 120 of the present application intersect to form an L shape.

[0028] In some embodiments, a connecting tooth structure can be provided on both the first connecting arm 110 and the second connecting arm 120 of the present application. When both the first connecting arm 110 and the second connecting arm 120 of the present application are provided with a connecting tooth structure, the connecting arm 110 and the second connecting arm 120 of the present application are installed in the composite material frame cavity in conjunction with the insert structure 200.

[0029] In some embodiments, the connecting teeth 111 are disposed on the first connecting arm 110, and the second connecting arm 120 has a first connecting surface 121, the first connecting surface 121 is used to contact the cavity of the composite frame, and the first connecting surface 121 is a planar structure. When the first connecting arm 110 of the present application is provided with the connecting teeth 111, and the second connecting arm 120 is not provided with the connecting teeth structure, under the installation strength that meets the pull-out force of 200N, the connecting angle code 100 can reduce the installation steps during the installation process and improve the installation efficiency.

[0030] like Figure 1As shown, in some specific embodiments, the first connecting arm 110 of the connecting angle code 100 of the present application is provided with connecting teeth 111, and the first connecting surface 121 of the second connecting arm 120 is not provided with connecting teeth, but is replaced by a plane structure. In some embodiments, the end of the second connecting arm 120 is provided with a guide mechanism 130, and the cross-section of the guide mechanism 130 is smaller than the cross-section of the composite frame cavity, so as to facilitate the insertion of the second connecting arm 120 into the composite frame cavity.

[0031] In some embodiments, the first connecting arm 110 and the second connecting arm 120 of the present application are hollow structures, and the first connecting arm 110 and the second connecting arm 120 are provided with first reinforcing ribs 114 at the connecting surfaces, and the first reinforcing ribs 114 are used to increase the connection strength at the corners of the connecting angle code 100.

[0032] In some embodiments, in order to further increase the strength of the first connecting arm 110 and the second connecting arm 120, the first connecting arm 110 is provided with a second reinforcing rib 115, which extends along the second direction Y and is arranged at intervals inside the first connecting arm 110 to strengthen the strength of the first connecting arm 110. Similarly, the second connecting arm 120 is provided with a third reinforcing rib 122, which extends along the first direction X and is arranged at intervals inside the second connecting arm 120 to strengthen the strength of the second connecting arm 120. In the present application, the connecting angle code 100 adopts a hollow structure with a reinforcing rib structure, which reduces the weight of the overall structure while ensuring the connection strength of the connecting angle code 100.

[0033] In some embodiments, the present application further optimizes the structure of the connecting teeth 111, such as Figure 1 and Figure 2 As shown, the connecting tooth 111 in the embodiment of the present application has a second connecting surface 112; the direction from the bottom end of the second connecting surface 112 to the top end of the second connecting surface 112 is inclined toward the second connecting arm 120, that is, the second connecting surface 112 of the connecting tooth 111 is an inclined structure, and the second connecting surface 112 is inclined toward the second connecting arm 120, which is convenient for the first connecting arm 110 to be inserted into the composite material frame cavity, and has reverse pull-out resistance while facilitating installation and increasing connection stability.

[0034] In some embodiments, the cross-section (XY cross-section) of the connecting tooth 111 is a trapezoidal structure, and the cross-section of the connecting tooth 111 gradually decreases from the bottom end of the connecting tooth 111 to the top end of the connecting tooth 111. The connecting tooth 111 in the embodiment of the present application extends along the third direction Z on the first connecting arm 110. When the connecting angle code 100 is driven into the composite material frame cavity, the top surface of the connecting tooth 111 will directly contact the inner wall of the cavity, generating resistance. In the embodiment of the present application, the connecting tooth 111 is set to have a trapezoidal structure in cross-section, which reduces the area of ​​the top surface of the connecting tooth 111, thereby reducing the insertion resistance of the connecting angle code 100. Because the second connecting surface 112 of the connecting tooth 111 is tilted and the trapezoidal structure (the cross-section gradually increases from top to bottom), the connection strength of the connecting tooth 111 is guaranteed, and the insertion resistance of the connecting angle code 100 is reduced, and its installation strength is increased, that is, when the connecting angle code 100 is pulled out, greater resistance is required.

[0035] In some embodiments, the connecting tooth 111 has a third connecting surface 113, the third connecting surface 113 is perpendicular to the first direction X, and the cross section formed by the connecting tooth 111 on the XY cross section is a right-angled trapezoidal structure, see Figure 3 In the embodiment of the present application, the third connecting surface 113 of the connecting tooth 111 is vertically arranged, which ensures the structural strength of the connecting tooth 111 to the greatest extent, and ensures the clamping strength between the connecting tooth 111 and the clamping portion 201 of the sleeve structure 200 and the installation strength and installation stability of the connecting angle code 100.

[0036] like Figure 3 As shown, the insert structure 200 in the embodiment of the present application includes a connecting portion 210, and the connecting portion 210 includes a first connecting portion 211 and second connecting portions 212 arranged on both sides of the first connecting portion 211. The first connecting portion 211 and the second connecting portions 212 arranged on both sides form a frame-shaped structure, which is clamped on the outer periphery of the first connecting arm 110. The second clamping portion 201 is arranged on the first connecting portion 211, and the clamping portion 201 is clamped with the connecting teeth 111 to fix the connecting angle code 100 inside the composite material frame.

[0037] In some embodiments, the clamping parts 201 in the embodiments of the present application are arranged in a staggered manner along the extension direction of the first central axis O1. In other embodiments, one end of each clamping part 201 extends to the other side of the first central axis O1, that is, the orthographic projection of each clamping part 201 on the first connecting part 211 intersects with the first central axis O1. The staggered clamping parts 201 can increase the connection strength between the insert structure 200 and the connecting angle code 100 while simplifying the structure. When the clamping parts 201 are arranged in a staggered manner along the direction of the first central axis O1, and one end thereof extends to the first central axis O1, the clamping parts 201 are arranged in a staggered manner along the direction of the first central axis O1. 1_On the other side, the connection strength between the angle code 100 and the inserting structure 200 can be further increased.

[0038] In some embodiments, the insert structure 200 includes a guide portion 220, one end of which is connected to the connecting portion 210, and the guide portion 220 is contracted inwardly, and the cross section of the guide portion 220 is smaller than the cross section of the composite frame cavity. The cross section of the guide portion 220 is smaller than the cross section of the cavity, which can play a guiding role when the connecting angle bracket 100 is inserted into the cavity, thereby increasing the installation efficiency of the connecting angle bracket 100.

[0039] In some embodiments, the guide portion 220 includes a first guide portion 221 and a second guide portion 222, wherein one end of the first guide portion 221 is connected to the first connecting portion 211, and one end of the second guide portion 222 is connected to the second connecting portion 212. Figure 3 As shown, the sleeve structure 200 has a first central axis O1, and the second guide portion 222 extends toward the first central axis O1 to form a necking structure. In a specific embodiment, the first guide portion 221 and the second guide portion 222 are metal connecting sheets, which have low cost and simple structure during the processing and forming process, and can be integrally formed with the connecting portion 210.

[0040] In some embodiments, the present application further optimizes the structure of the clamping portion 201. Figure 3 As shown, the insert structure 200 has a first end 202 and a second end 203, and the bottom end of the clamping part 201 to the top end of the clamping part 201 extend toward the second end 203. The bottom end of the clamping part 201 in this application refers to the place where it is connected to the first connecting part 211, and the top end of the clamping part 201 refers to the side arranged opposite to the bottom end of the clamping part 201. In the embodiment of this application, the clamping part 201 forms a slope structure. Figure 4 As shown, the connecting angle code 100 is inserted into the composite frame cavity along the first direction X, and the inclined structure of the clamping portion 201 reduces the insertion resistance of the connecting angle code 100 and increases the removal resistance of the connecting angle code 100, thereby reducing the installation difficulty and increasing the connection stability of the structure.

[0041] like Figure 4 As shown, the composite material frame 3 in the embodiment of the present application has a cavity 300, and the connecting mechanism 1 is installed in the composite material photovoltaic frame cavity 300 for connecting the composite material photovoltaic frame.

[0042] In some embodiments, the inner wall of the composite frame profile of the present application is provided with a fourth reinforcing rib 301 to increase the strength of the composite frame. In a specific embodiment, the inner wall of the cavity 300 may be provided with a single or multiple fourth reinforcing ribs extending along the length direction of the frame profile, and the fourth reinforcing ribs may be provided on any inner surface of the frame cavity. The fourth reinforcing rib 301 in the embodiment of the present application may be formed by a pultrusion process.

[0043] In some embodiments, when the present application adopts a situation where both the first connecting arm 110 and the second connecting arm 120 have connecting tooth structures, fourth reinforcing ribs 301 can be set inside the two frame cavities connected by the connecting angle code 100.

[0044] In some embodiments, the first connecting arm 110 of the present application is provided with connecting teeth 111, and the connecting surface of the second connecting arm 120 is a planar structure. At this time, the frame surface connected to the second connecting arm 120 can be provided with a fourth reinforcing rib 301 or not.

[0045] In some embodiments, the frame reinforcement ribs of the present application are arranged on two opposite sides of the frame cavity, which can increase the strength of the frame, and the inner wall of the cavity retains two planar structures to increase the connection strength between the connecting arm or the sleeve structure 200 and the cavity using glue.

[0046] like Figure 5 and Figure 6 As shown, the composite frame profile of the present application includes a first frame 310 and a second frame 320. In a specific embodiment, the first frame 310 is a long frame, and the second frame 320 is a short frame structure. The connection mechanism 1 of the present application is installed in the following manner:

[0047] (a) Apply glue to the inner surface of the cavity of the second frame 320, insert the second connecting arm 120 of the connecting angle code 100 into the cavity of the second frame 320, and wait for the glue to solidify;

[0048] (b) Apply glue to the inner surface of the cavity of the first frame 310, and then insert the C-shaped insert structure 200 with the clamping part 201 into the cavity of the first frame 310. After the glue is solidified and the insert structure 200 is firmly bonded to the first frame 310, insert the combination of the second frame 320 and the connecting angle code 100 obtained in step (a) into the insert structure 200 that has been solidified with the first frame 310, and the connecting teeth 111 provided on the first connecting arm 110 are mechanically connected and fixed with the clamping part 201 of the insert structure 200. The connecting angle code 100 of the present application can meet the pull-out force of 200N, and the connecting angle code 100 will not fall off the frame.

[0049] After the composite photovoltaic frame of the embodiment of the present application is connected, the formed frame connection structure is combined to form a frame for fixing the solar panel, which is used to fix the photovoltaic cell. The length of the frame can be customized according to the size of the solar panel.

[0050] The photovoltaic frame in the present application can be quickly assembled when used in conjunction with the connecting angle code. During the implementation process, there is no need to drill holes in the frame to destroy the main structure of the frame profile. The fixing of the sleeve structure and the frame profile is in the form of gluing, which can be achieved through automated equipment, thereby improving assembly efficiency.
