[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a quick-packing solar photovoltaic panel frame, such as... Figures 1 to 5 As shown, the device includes a long frame 1 and a short frame 2. The upper surface of the long frame 1 has an upper horizontal arm 101 on one side, and a lower horizontal arm 102 on the side of the long frame 1 away from the upper horizontal arm 101. A longitudinal connecting arm 103 is constructed between the upper horizontal arm 101 and the lower horizontal arm 102. A insertion groove 104 is opened in one longitudinal connecting arm 103 of the long frame 1. An edge 105 is provided at the front end of the longitudinal connecting arm 103 near the insertion groove 104. A groove 106 is provided on the inner top wall and the inner bottom wall of the insertion groove 104. A first sealing groove 107 is provided between the two longitudinal connecting arms 103. A second sealing groove 108 is opened between the longitudinal connecting arm 103 and the lower horizontal arm 102. The long frame 1 and the short frame 2 surround the four sides of the solar photovoltaic cell module to form a rectangular frame. An angle bracket 3 is rubbed between the long frame 1 and the short frame 2.

[0027] In the photovoltaic panel frame system, it mainly consists of two long frame 1 and two corresponding short frame 2 connected to each other to form a complete frame structure, which is used to support and protect the solar photovoltaic panel. However, if the connection is too loose during encapsulation, the frame cannot be firmly fixed to the photovoltaic panel, which will affect the stability of the entire photovoltaic module. If the connection is too tight, it may cause the frame to deform during installation, or make it difficult to operate during disassembly and maintenance. In the designed frame, the upper horizontal arm 101 and the lower horizontal arm 102 have basic load-bearing capacity and also have certain protective characteristics to ensure the integrity of the solar cells.

[0028] Meanwhile, the first sealing groove 107 and the second sealing groove 108 designed on the longitudinal connecting arm 103 are both filled with sealant. This sealant will provide a reliable sealing guarantee for the overall structure, effectively preventing the intrusion of impurities such as moisture and dust, and ensuring the stable operation of internal components. It is worth noting that the edge 105 set at the opening on one side of the frame of the longitudinal connecting arm 103 forms a 45° angle with the vertical direction of the longitudinal connecting arm 103, so that the top of the edge 105 is close to the inside of the insertion groove 104. While improving the structural stability, it also optimizes the compactness of the connection between components. Moreover, the grooves 106 are opened on the two inner side walls of the insertion groove 104. The grooves 106 reserve more operating space for subsequent prefabrication processes, making the installation of additional accessories more convenient and efficient, and laying a solid foundation for the smooth progress of the entire prefabrication process.

[0029] An insertion portion 301 is provided on both sides of one side surface of the corner bracket 3. A friction structure 302 is provided on one side surface of the insertion portion 301. One end of the insertion portion 301 extends through to the inner wall of the insertion groove 104. One side of the insertion portion 301 abuts against the inner wall of the insertion groove 104. The friction structure 302 on the other side of the insertion portion 301 extends to the opening of the longitudinal connecting arm 103 and is movably engaged with one end of the edge 105. A weight reduction groove 303 is provided on the upper surface of the corner bracket 3. Both the upper and lower surfaces of the corner bracket 3 abut against the inner wall of the insertion groove 104.

[0030] The corner bracket 3 plays a crucial connecting role in this structural system, tightly connecting the long frame 1 and the short frame 2 to ensure the stability and integrity of the entire frame. The corner bracket 3 has adaptable insertion parts 301 on both sides, which can be fully embedded into the insertion slot 104, providing a foundation for subsequent stable connection. A friction structure 302 is provided on one side of the corner bracket 3. This friction structure 302 is arranged in a regular sawtooth pattern, with each sawtooth having a certain angle. When two adjacent sawtooth shapes form a specific angle, they can abut against the top of the edge 105. Thus, during actual installation, as the insertion part 301 moves deeper into the insertion slot 104, the edge 105, with its 45° angle, will engage with the recessed area between the two sawtooth shapes. This process not only utilizes the fitting characteristics and automatic locking between geometric shapes but also enhances the tightness of the connection between the corner bracket 3 and the frame, effectively preventing loosening and displacement, and providing a reliable guarantee for the entire frame system to maintain high strength and high stability during long-term use.

[0031] The locking arm 401 has arc-shaped connecting surfaces 402 on both front ends. The outer arc surface of the arc-shaped connecting surface 402 is placed inside the insertion slot 104. One end of the locking arm 401 extends into the long frame 1, and the other end of the locking arm 401 extends into the short frame 2. One end of the arc-shaped connecting surface 402 has a curved abutment end 403 at its bottom. One side of the curved abutment end 403 abuts against the inner sidewall of the two edges 105. There are four corner brackets 3, which are arranged in pairs. One set of corner brackets 3 is used to connect one side of the short frame 2 to the two long frames 1. The inner arc surface of the arc-shaped connecting surface 402 is placed at the front end of the insertion part 301.

[0032] Meanwhile, a latching assembly 4 is fitted onto the outer arc surface of the corner bracket 3. The locking arms 401 on both sides of the latching assembly 4 have elastic properties. When it needs to be inserted into the insertion slot 104, since the pre-designed expansion range of the locking arms 401 is slightly larger than the inner diameter of the insertion slot 104 in its natural state, at the moment of initial insertion, the locking arms 401 will be squeezed by the slot wall and then retract inward to enter the inlet. Once it is fully inserted into the insertion slot 104, the previously accumulated elastic potential energy is released instantly, driving the locking arms on both sides to retract inward. 401 fits tightly against the inner wall of the insertion slot 104 with strong elasticity, forming a tight and seamless abutment effect. This abutment, through the continuous action of elasticity, applies stable and uniform pressure in the direction perpendicular to the slot wall, avoiding any possible loosening gaps. This ensures the connection between the corner bracket 3 and the insertion slot 104, allowing operators to complete the frame assembly by hand without the need for professional tools, shortening the installation time and enabling the product to be put into use quickly. It is especially suitable for large-scale production assembly lines, effectively improving production efficiency.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
