[0002] With the rapid development of photovoltaic technology, the installation scenarios for solar panels are becoming increasingly diversified, from large-scale ground power stations to rooftop distributed systems and mobile emergency equipment, which places higher demands on the lightweighting of the component frames, structural strength, and installation efficiency.

[0003] Traditional solar panel frames mostly use aluminum alloy profiles, which offer some lightweight advantages. However, with the increasing size of modules and the growing demand for flexibility, the limitations of existing structures in terms of weight reduction potential, rapid assembly capabilities, and local strength optimization are becoming increasingly apparent. Especially in distributed rooftop scenarios, the frame's weight directly affects the building's load-bearing safety; while in mobile applications such as vehicles and drones, the need for lightweight design and rapid assembly / disassembly efficiency have become key pain points.

[0004] To address these issues, we have developed a lightweight frame structure for solar panels. Utility Model Content

[0010] The present invention is further configured such that a spring is fixedly connected to the inner cavity of the limiting block, a drive plate is fixedly connected to the other end of the spring, and a drive block is fixedly connected to one side of the drive plate. By designing a drive wheel, the drive wheel drives the drive plate to move through the drive block, and the drive plate drives the card block to move so that it is inserted into the corresponding limiting groove.

[0011] The present invention is further configured such that a groove is provided on one side of the connecting frame, and one end of the bolt rod passes through the inner cavity of the groove and is fixedly connected to a drive cap. By designing a drive wheel, the drive wheel drives the drive plate to move through the drive block, and the drive plate drives the locking block to move so that it is inserted into the corresponding limiting groove.

[0012] The present invention is further configured such that the reinforcing cylinder and the reinforcing block are integrally formed, and the number of the reinforcing blocks is four.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model uses a single rotating drive cap to drive the bolt rod, threaded sleeve and support rod in linkage, so that the push plate simultaneously pushes four sets of locking blocks into the locking slot, which improves the fastening efficiency compared to traditional bolts; the spring forms a continuous rebound force with the locking blocks through the drive plate, and with the wedge-shaped guide surface of the limit block inner cavity, it can realize the function of quick disassembly.

[0015] 2. This utility model uses thin-walled high-strength aluminum alloy for the fixing frame and connecting frame, combined with the honeycomb support design of the internal reinforcing cylinder. The reinforcing block and reinforcing cylinder adopt an integrated biomimetic rib structure. Through topology optimization, the material is efficiently distributed, improving the local bending stiffness and avoiding the risk of instability caused by thinning the wall thickness.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model is a lightweight frame structure for solar panels, including a fixed frame 1 and a connecting frame 2. The fixed frame 1 and the connecting frame 2 have the same width. The connecting frame 2 has a snap-fit ​​assembly in its inner cavity. The snap-fit ​​assembly includes a bolt rod 3 that is movably connected to the inner wall of the connecting frame 2 through a bearing seat, a limiting block 4 that is fixedly connected to one side of the connecting frame 2, a snap block 5 that is set in the inner cavity of the limiting block 4, and snap grooves 6 that are opened at the top and bottom of the fixed frame 1. The fixed frame 1 has a reinforcement assembly in its inner cavity. The reinforcement assembly includes a fixing groove 7 that is opened in the inner cavity of the fixed frame 1, a reinforcement cylinder 8 that is set in the inner cavity of the fixed frame 1, and a reinforcement block 9 that is fixedly connected to the surface of the reinforcement cylinder 8.

[0027] Further details: Both the fixed frame 1 and the connecting frame 2 are made of lightweight alloy material, which ensures structural strength while reducing the overall weight of the frame. There are four fixed connecting limit blocks 4 on one side of the connecting frame 2, and each limit block 4 has two internal cavity locking blocks 5 to ensure the firmness of the splicing of the fixed frame 1 and the connecting frame 2. The reinforcing cylinder 8 has a hollow structure design to ensure the uniformity of its stress.

[0028] Example 2

[0029] Please see Figures 1-5Based on embodiment 1, a threaded sleeve 10 is threadedly connected to the surface of the bolt rod 3, a support rod 11 is movably connected to the surface of the threaded sleeve 10, a push plate 12 is movably connected to the other end of the support rod 11, a drive wheel 13 is fixedly connected to one side of the push plate 12, one end of the drive wheel 13 passes through the inner cavity of the limiting block 4, a spring 14 is fixedly connected to the inner cavity of the limiting block 4, a drive plate 15 is fixedly connected to the other end of the spring 14, a drive block 16 is fixedly connected to one side of the drive plate 15, a groove 17 is opened on one side of the connecting frame 2, one end of the bolt rod 3 passes through the inner cavity of the groove 17 and is fixedly connected to a drive cap 18, the reinforcing cylinder 8 and the reinforcing block 9 are integrally formed, and there are four reinforcing blocks 9.

[0030] Further details: Through the cooperation of threaded sleeve 10, support rod 11 and push plate 12, the rotating bolt rod 3 is driven by threaded sleeve 10 and support rod 11 to move push plate 12. The design of drive wheel 13 drives drive plate 15 through drive block 16, and drive plate 15 drives block 5 to move, so that it is inserted into the corresponding limit groove. The design of drive cap 18 makes it convenient for the operator to drive the bolt rod 3 to rotate with a wrench. The design of reinforcing cylinder 8 and reinforcing block 9 is integrated to increase the overall structural strength. The hidden design of groove 17 and drive cap 18 avoids interference from the external protruding structure and supports curved surface installation and compact space deployment.

[0031] The working principle of this utility model is as follows: The reinforcing cylinder 8 is inserted into the fixing groove 7 in the inner cavity of the fixing frame 1. The four circumferentially distributed reinforcing blocks 9 are interference-fitted with the frame to form an internal multi-point support network, which disperses the stress concentration area and aligns the width matching surfaces of the fixing frame 1 and the connecting frame 2. The inner cavity locking block 5 of the limiting block 4 of the connecting frame 2 is initially embedded into the guide part of the locking groove 6 of the fixing frame 1. The drive cap 18 is rotated with a hex wrench to drive the bolt rod 3 to rotate. The threaded sleeve 10 moves axially under the thread drive of the bolt rod 3. The hinged support rod 11 pushes the push plate 12 to move towards the limiting block 4. The drive wheel 13 of the push plate 12 pushes the drive block 16, compresses the spring 14 and forces the drive plate 15 to drive the locking block 5 to be completely wedged into the locking recess of the locking groove 6, thereby realizing mechanical self-locking.
