Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic frame technology, and in particular relates to a lightweight integrated photovoltaic frame. Background Technology

[0002] With the popularization of photovoltaic technology and the rise of outdoor activities, the demand for portable photovoltaic power generation equipment is increasing. Such equipment is required to be lightweight, robust and highly integrated.

[0003] Currently, the frames used in portable photovoltaic products on the market often have the following defects: 1. Bulky structure and poor portability: Traditional photovoltaic panels usually adopt a frame structure with hollow aluminum profiles on all four sides. Although this structure is sturdy, it consumes a lot of materials and is heavy, which runs counter to the goal of lightweighting pursued by portable devices.

[0004] 2. Dispersed functions and low integration: Existing products typically have electrical components such as micro inverters, junction boxes, and output interfaces (USB / AC) that are independently external or installed separately, which takes up space and causes problems such as messy cables.

[0005] 3. The contradiction between structural strength and lightweight: Simplifying the frame structure in order to reduce weight (such as using only a thin back panel) often sacrifices the bending and torsional strength of the overall frame, which can easily cause hidden cracks or damage during transportation or use, affecting product life and reliability.

[0006] Therefore, there is an urgent need in this field for a new type of frame structure that can significantly reduce weight while ensuring structural strength, and integrate all functional components to provide users with a truly integrated, portable, and ready-to-use photovoltaic power generation solution. Summary of the Invention

[0007] The purpose of this invention is to provide a lightweight integrated photovoltaic frame. It uses two single-piece plate end plates as the frame in the width direction and simple vertical plates as the short side components, replacing the traditional heavy cavity profiles. This greatly reduces the amount of material used and achieves significant weight reduction. Through the design of functional beams, it has the advantages of functional integration and compensation for frame strength. It not only does not add redundant weight, but also plays a key "reinforcing" role, effectively compensating for the overall structural strength and torsional performance that may be lost due to the simplification of the short side.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a lightweight integrated photovoltaic frame, comprising two profiles, two end plates, a functional beam, and a cover plate; The profile is a thin-walled hollow aluminum profile; The end plate is a single-piece plate structure. Both ends of the end plate are integrally provided with an inward fold. The end plate is located between one end of the two profiles. The inward fold is fixed to the outer side of the end of the profile by fastening screws. The functional beam is a hollow square beam with connecting ends fixed at both ends. The functional beam is located in the middle between the two profiles and is distributed parallel to the end plate. The connecting ends are fixed to the inside of the profiles by fastening screws. The top surface of the middle part of the functional beam is provided with a tapered operating port. The functional beam is provided with a junction box, an inverter and a preset wire. One end of the functional beam is provided with a wire-passing port. The preset wire passes through the wire-passing port and is connected to a waterproof connector. A sealing sleeve is provided at the connection between the preset wire and the wire-passing port. The cover plate includes a conical cover, with positioning edges on both sides of the bottom of the conical cover. The gap of the conical cover is set at the operating port. The two positioning edges are respectively fitted to the inner sides of the functional beam. The conical cover has a through opening at the center. The top edge of the operating port is fixed with a lower sealing strip that fits against the conical cover, and the top surface of the conical cover is fixed with an upper sealing strip.

[0009] Furthermore, the profile includes a rectangular tubular body, a back plate portion is provided at the top edge of the body, a cover edge is provided at the top edge of the back plate portion, and a component mounting cavity is formed between the cover edge, the back plate portion and the top of the body.

[0010] Furthermore, the upper surface of the functional beam and the upper surface of the conical cover are both flush with the upper surface of the main body.

[0011] Furthermore, the inner fold is provided with a first preset hole, and the outer sides of both ends of the profile are provided with a second preset opening. The inner fold is fixed to the outer side of the end of the profile by fastening screws, the first preset hole and the second preset opening.

[0012] Furthermore, a first sealing gasket is fixed on the inner side of both ends of the end plate near the inward fold, and the end face of the profile contacts the first sealing gasket.

[0013] Furthermore, the outer side of the connecting end is provided with a threaded opening, the depth of which is less than the thickness of the connecting end, the middle of the profile is provided with a third preset opening, and the connecting end is fitted to the inner side of the profile with a second sealing gasket between them.

[0014] This utility model has the following beneficial effects: 1. This utility model uses two single-piece plate end plates as the frame in the width direction and simple vertical plates as the short side components, replacing the traditional heavy cavity profiles, which greatly reduces the amount of material used and achieves significant weight reduction. Through the design of functional beams, it has the advantages of functional integration and compensation for frame strength. It not only does not increase redundant weight, but also plays a key "reinforcing rib" role, effectively compensating for the overall structural strength and torsional performance that may be lost due to the simplification of the short side, ensuring the safety and reliability of photovoltaic modules in transportation and use, and successfully solving the contradiction between lightweight and robustness.

[0015] 2. This utility model can seal the ends of the profile by designing the first sealing gaskets at both ends of the end plate. By designing the second sealing gasket between the connecting end and the profile, and by designing the threaded blind end on the connecting end, the end of the functional beam is sealed, thus ensuring the overall sealing degree of the frame and improving the corrosion and oxidation resistance.

[0016] 3. The present invention features an operating port and a cover plate. The operating port is used for the installation and arrangement of various components within the functional beam, while the cover plate design ensures the sealing effect of the operating port, thereby improving its waterproof and moisture-proof capabilities and service life.
