Among them, foldable photovoltaic carports have become the focus of market attention due to their portability and small footprint.

[0003] Currently, the structural design of existing foldable photovoltaic carports focuses on the flexibility of the folding mechanism to achieve rapid storage and unfolding. However, there are significant shortcomings in the stability of the photovoltaic panels after unfolding and the reliability of their fixation after folding. Specifically, most products use simple buckles to fix the photovoltaic panels in the unfolded state. When used outdoors, they are easily affected by external forces such as wind and vibration, which can lead to loose connections or even structural displacement. This not only affects the photovoltaic power generation efficiency but also poses safety hazards. Therefore, we need to provide a foldable photovoltaic carport. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a foldable photovoltaic carport, comprising:

[0024] The mounting frame 1, photovoltaic panel 2, and fixing mechanism 3 are provided. The photovoltaic panel 2 is slidably installed inside the mounting frame 1. The fixing mechanism 3 is installed on one side of the photovoltaic panel 2 and is used to fix the photovoltaic panel 2 after it is unfolded and after it is stored.

[0025] The fixing mechanism 3 includes a long plate 31, limiting bolts 32, clamps 33 and pressing member 34. The long plate 31 is fixed in the mounting frame 1 and has two limiting bolts 32 installed in the internal thread. The two limiting bolts 32 are respectively installed in the internal threads of the two clamps 33. The pressing member 34 is installed in the movable end of the photovoltaic panel group 2 and is used to elastically pull the two clamps 33.

[0026] Specifically, by setting up the fixing mechanism 3, the photovoltaic panel group 2 can be easily fixed when it is unfolded and when it is stored. When unfolded, the cooperation of the long plate 31, the limiting bolt 32 and the clamp 33 can form a stable lock. Combined with the elastic force of the holding member 34, it can effectively resist external forces such as wind, prevent the photovoltaic panel group 2 from loosening and shifting, and ensure power generation efficiency and safety of use. When stored, the mechanism can quickly tighten and fix multiple photovoltaic panels to prevent relative sliding in the stacked state, extend the equipment life, greatly simplify the unfolding and storage process, and improve the user experience.

[0027] The photovoltaic panel group 2 is composed of multiple photovoltaic panels, and the multiple photovoltaic panels are hinged with connecting plates 4. Columns 5 are fixedly installed on both sides of the photovoltaic panels, and the mounting frame 1 has a sliding groove 6 for the movement of the columns 5.

[0028] Furthermore, multiple photovoltaic panels are hinged together by stainless steel hinges with 3-5mm thick polycarbonate connecting plates 4. The edges of the connecting plates 4 are rounded. The columns 5 on both sides of the photovoltaic panels are made of 45# steel and are fixed to the photovoltaic panel frame by welding. The diameter of the columns 5 is 1-2mm smaller than the width of the slide 6, and the surface of the columns 5 is polished. The slide 6 of the mounting frame 1 is made of one-piece aluminum alloy, and the inner wall of the slide 6 is pasted with a 0.5mm thick polytetrafluoroethylene wear-resistant layer. Multiple photovoltaic panels are hinged through the connecting plates 4 to achieve flexible rotation. The cooperation between the columns 5 and the slide 6 ensures smooth sliding when the photovoltaic panel assembly 2 is unfolded and stored. The polytetrafluoroethylene layer reduces friction loss, solves the problem of jamming during folding, and improves service life.

[0029] The photovoltaic panel at the inner limit end of the photovoltaic panel group 2 is rotatably installed in the mounting frame 1, and the remaining photovoltaic panel surface columns 5 slide in the sliding groove 6, and the column 5 surface is fixedly installed with a limit ring 7;

[0030] It is worth noting that the photovoltaic panels at the inner limit end of the photovoltaic panel group 2 are rotatably mounted on the inner bearing seat of the mounting frame 1 via 304 stainless steel bearings. The outer ring of the bearing is interference-fitted with the bearing seat, and the inner ring is transition-fitted with the rotating shaft of the photovoltaic panel. After the column 5 of the remaining photovoltaic panels passes through the slide groove 6, the limit ring 7 is made of 6061 aluminum alloy and is fixed to the column 5 by M6 hexagonal bolts. The diameter of the limit ring 7 is 5-8mm larger than the width of the slide groove 6. The bearing connection ensures smooth rotation of the photovoltaic panels at the limit end. The limit ring 7 effectively prevents the photovoltaic panels from detaching from the mounting frame 1, solving the safety hazard of falling off during sliding. The bolt connection facilitates later maintenance and replacement.

[0031] After the photovoltaic panel is stored, a counterweight 8 is fixedly installed at the bottom of one side of the photovoltaic panel, which is used to rotate the photovoltaic panel towards the side with the counterweight 8.

[0032] It should be noted that the counterweight 8 is made of cast iron and is fixed in the groove at the bottom of the photovoltaic panel by countersunk bolts. The counterweight 8 weighs 0.8-1.2kg, and the vertical distance between its center of gravity and the hinge axis of the photovoltaic panel is 8-12cm. The outer surface of the counterweight 8 is coated with a 200℃ high-temperature resistant epoxy resin coating. The counterweight 8 uses gravity to make the photovoltaic panel rotate in an oriented manner when stored, ensuring a consistent folding trajectory and solving the trouble of manual sorting. The coating treatment improves outdoor weather resistance and prevents rust from affecting balance.

[0033] The holding member 34 includes a frame 341, a spring 342 and a movable plate 343. The frame 341 is fixed on the photovoltaic panel near the long plate 31 in the photovoltaic panel group 2. The movable plate 343 is installed inside the frame 341 by multiple springs 342. One end of each of the two clamps 33 is fixed to the surface of the movable plate 343.

[0034] Specifically, the frame 341 of the clamping component 34 is injection molded from ABS engineering plastic and fixed to the photovoltaic panel frame with stainless steel screws. The spring 342 is a cylindrical helical compression spring made of 65Mn material, with a diameter of 5-8mm and a free length of 30-40mm. The two ends of the spring 342 are welded and fixed to the bottom of the frame 341 and the back of the movable plate 343, respectively. The movable plate 343 is stamped from Q235 steel plate with a thickness of 2-3mm and a galvanized surface. The spring 342 provides stable elastic tension to ensure that the clamp 33 fits tightly against the fixed component. The ABS frame 341 is lightweight and insulated, avoiding affecting the conductivity of the photovoltaic panel and solving the problems of conductivity hazards and excessive weight of metal components.

[0035] A handle is fixedly installed on the surface of the movable plate 343, and adhesive sheets 9 are fixedly installed on the inner walls of the two clamps 33.

[0036] The handle is made of TPU soft rubber and is integrally molded with the movable plate 343 through a secondary injection molding process. The surface has anti-slip texture. The adhesive layer 9 is made of silicone material with a Shore hardness of 60-70 and is attached to the inner wall of the clamp 33 with 3M double-sided adhesive. The adhesive layer 9 is 1-2mm thick and has diamond-shaped anti-slip bumps pressed on the surface. The TPU handle is comfortable to hold and anti-slip. The silicone adhesive layer 9 enhances friction to prevent slippage when clamped and avoids hard contact that could damage the surface of the photovoltaic panel, thus solving the problems of slippage and scratches during fixing.

[0037] The surface of the frame 341 is provided with abutment members for fixing the movable plate 343;

[0038] The abutment includes a knob screw and a rubber abutment head. The knob screw is threaded to the side wall of the frame 341. The end of the screw is connected to a 15-20mm diameter nitrile rubber abutment head through a ball joint structure. The surface of the abutment head is provided with an annular anti-slip ridge. Rotating the knob screw can push the abutment head to tightly abut against the movable plate 343, thereby temporarily locking the holding member 34. The ball joint structure ensures that the abutment surfaces fit tightly. The nitrile rubber material is wear-resistant and anti-slip, solving the problem of fixation failure when the spring 342 has insufficient elasticity.

[0039] The multiple photovoltaic panels in the photovoltaic panel group 2 involved in this application are connected to the external PLC controller and power supply using existing mature technologies. The connection to the external PLC controller and power supply is a conventional technical means in this field, so the specific circuit connection, control logic and working process will not be described in detail.

[0040] All threaded mounting surfaces in this application utilize a modified triangular thread with a self-locking function. The thread helix angle is designed to be 1.5°-2.5° to enhance the anti-loosening effect. After phosphating, the thread surface is coated with an 8-12μm Dacromet coating and impregnated with silicone sealant to form a sealing layer, resulting in excellent corrosion resistance. Furthermore, the thread effectively expels dust, allowing for normal operation even with a small amount of dust adhering to it.

[0041] When the photovoltaic panel assembly 2 is unfolded and fixed, the two limiting bolts 32 inside the long plate 31 are rotated, causing the limiting bolts 32 to be threaded into the threaded holes inside the clamp 33, thereby fixing the clamp 33 and securing the unfolded photovoltaic panel assembly 2. The movable plate 343 at one end of the clamp 33 can be fixed via an abutment. When retracting, the limiting bolts 32 are not threaded into the clamp 33. Pushing the handle moves the photovoltaic panels closest to the long plate 31 away from the long plate 31. A counterweight 8 is provided at the bottom of each photovoltaic panel to ensure consistent rotation in each direction. To ensure that the photovoltaic panel assembly 2 can be retracted, the movable plate 343 is moved by pulling the handle, and the two clamps 33 on the surface of the movable plate 343 move, limiting the photovoltaic panel assembly 2. Under the action of the spring 342, the two clamps 33 press and hold the photovoltaic panel assembly 2 after it is retracted, preventing the photovoltaic panel assembly 2 from unfolding on its own. The inner wall of the clamps 33 is provided with an adhesive layer 9, which increases the friction for adhering to the photovoltaic panel assembly 2 and has a protective function. At the same time, frame-type adhesive can be installed on the surface of the photovoltaic panel to prevent friction after the photovoltaic panel assembly 2 is retracted.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
