Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a foldable photovoltaic module. Background Technology

[0002] Traditional photovoltaic (PV) modules are becoming increasingly larger and heavier due to market demand for high-power, low-cost modules. This makes them inconvenient to carry and install. In certain special application environments, such as rooftop installations and portable power supply scenarios, traditional PV modules have limitations due to their weight and size. Therefore, there is a need to design a new type of lightweight, foldable, and portable PV module.

[0003] In the prior art, a portable, foldable, lightweight photovoltaic module is disclosed in patent application CN202020598357.5, which was examined and published by the China National Intellectual Property Administration. This module includes a first photovoltaic module and a second photovoltaic module with identical structures. The first and second photovoltaic modules are connected by several hinges to form a conventionally sized photovoltaic module. The hinges allow the first and second photovoltaic modules to fold together. The first photovoltaic module includes a photovoltaic panel and a frame. The frame includes an A-side frame for fixing the front of the photovoltaic panel, a B-side frame for fixing the side of the photovoltaic panel, and a C-side frame for fixing the back of the photovoltaic panel. The short side frame of the first photovoltaic module has a structure without a C-side frame. This invention is lightweight, foldable, and easy to carry.

[0004] However, photovoltaic modules require frequent inspection and maintenance during long-term use. During inspection and maintenance, the two sets of photovoltaic modules need to be separated. Since the two sets of photovoltaic modules are connected by a hinge, the maintenance personnel need to use external tools to disassemble the hinge. After the inspection and maintenance is completed, the hinge also needs to be reassembled with external tools. This disassembly and reassembly method is quite troublesome, making the separation and reassembly of the two sets of photovoltaic modules very troublesome and causing inconvenience to the maintenance personnel. Utility Model Content

[0005] The purpose of this invention is to provide a foldable photovoltaic module to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable photovoltaic module, comprising: a first photovoltaic module frame and a second photovoltaic module frame, wherein a groove is provided on the surface of the first photovoltaic module frame, a slider is slidably connected in the groove, a connecting rod is fixed on the surface of the slider, a connecting sleeve is fixed on the surface of the second photovoltaic module frame, the connecting rod is rotatably inserted into the connecting sleeve, and a limit structure is provided between the groove and the slider.

[0007] Preferably, there are two sets of connecting rods and two sets of connecting sleeves. The two sets of connecting rods are symmetrically distributed about the frame of the first photovoltaic module, and the two sets of connecting sleeves are symmetrically distributed about the frame of the second photovoltaic module. The connecting rods are L-shaped round rods, and the connecting sleeves are circular cylindrical structures.

[0008] Preferably, a spring groove is provided on the inner wall of the groove, and a push spring is provided in the spring groove. One end of the push spring extends out of the spring groove and abuts against the surface of the slider.

[0009] Preferably, one end of a guide rod is fixed on the inner wall of the groove at the end of the slide away from the spring groove, and the other end of the guide rod is fixed on the inner wall of the spring groove. A guide hole is provided on the surface of the slider, and the guide rod is movably inserted into the guide hole.

[0010] Preferably, the groove is a rectangular groove structure and the slider is a rectangular block structure.

[0011] Preferably, the limiting structure includes: a limiting groove, which is formed on the surface of the slider, and a limiting rod mounting groove is formed on the inner wall of the groove, wherein one end of the limiting rod is movably inserted into the limiting rod mounting groove, and the other end of the limiting rod is movably inserted into the limiting groove.

[0012] Preferably, the limiting rod has a circular rod structure, and a limiting spring is fixed between one end of the limiting rod that extends into the limiting rod mounting groove and the inner wall of the groove.

[0013] Preferably, a pull rod hole is formed on the surface of the first photovoltaic module frame, the pull rod hole is connected to the limit rod mounting groove, a pull rod is movably inserted into the pull rod hole, the pull rod has a "T" shaped round rod structure, the bottom end of the pull rod extends into the limit rod mounting groove and is fixed on the surface of the limit rod, and the top end of the pull rod extends out from the pull rod hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The foldable photovoltaic module proposed in this utility model, when no maintenance is required on the first and second photovoltaic module frames, has a limiting structure that restricts the sliders to one end of the slide groove. At this time, the two sets of sliders are located in the slide groove in a direction away from each other. One end of the "L"-shaped connecting rod is inserted into the connecting sleeve. Through the action of the connecting rod and the connecting sleeve, the first and second photovoltaic module frames can rotate relative to each other. When maintenance is required and the first and second photovoltaic module frames need to be disassembled, the limiting structure between the slide groove and the sliders is released, and the two sets of sliders automatically move towards each other. The movement of the two sets of connecting rods towards each other allows them to exit from the two sets of connecting sleeves, facilitating the separation of the first and second photovoltaic module frames. After maintenance, the two sets of connecting sleeves are aligned with the two sets of connecting rods, and the two sets of sliders are slid away from each other and the limiting structure is restarted. This allows the two sets of connecting rods to re-insert into the two sets of connecting sleeves and maintain the insertion state, thus merging the first and second photovoltaic module frames. This makes the separation and merging of the first and second photovoltaic module frames very convenient, bringing convenience to maintenance personnel. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a foldable photovoltaic module, comprising: a first photovoltaic module frame 1 and a second photovoltaic module frame 2, characterized in that: a groove 3 is provided on the surface of the first photovoltaic module frame 1, a slider 4 is slidably connected in the groove 3, a connecting rod 5 is fixed on the surface of the slider 4, a connecting sleeve 6 is fixed on the surface of the second photovoltaic module frame 2, the connecting rod 5 is rotatably inserted into the connecting sleeve 6, a limiting structure is provided between the groove 3 and the slider 4, two sets of connecting rods 5 and two sets of connecting sleeves 6 are provided, the two sets of connecting rods 5 are symmetrically distributed about the first photovoltaic module frame 1, the two sets of connecting sleeves 6 are symmetrically distributed about the second photovoltaic module frame 2, the connecting rod 5 has an "L" shaped round rod structure, and the connecting sleeve 6 has a circular cylindrical structure.

[0024] In actual use, when maintenance of the first photovoltaic module frame 1 and the second photovoltaic module frame 2 is not required, the limiting structure limits the slider 4 to one end of the slide groove 3. At this time, the two sets of sliders 4 are located in the slide groove 3 in a direction away from each other. One end of the "L"-shaped connecting rod 5 is inserted into the connecting sleeve 6. Through the action of the connecting rod 5 and the connecting sleeve 6, the first photovoltaic module frame 1 and the second photovoltaic module frame 2 can rotate relative to each other. When maintenance of the first photovoltaic module frame 1 and the second photovoltaic module frame 2 is required and they need to be separated, the limiting structure between the slide groove 3 and the slider 4 is released, and the two sets of sliders 4 automatically move closer to each other. The movement in the near direction allows the two sets of connecting rods 5 to exit from the two sets of connecting sleeves 6 respectively, thus facilitating the separation of the first photovoltaic module frame 1 and the second photovoltaic module frame 2. After maintenance, the two sets of connecting sleeves 6 are aligned with the two sets of connecting rods 5 respectively, and the two sets of sliders 4 are slid away from each other and the limiting structure is restarted. This allows the two sets of connecting rods 5 to be reinserted into the two sets of connecting sleeves 6 respectively and maintained in the inserted state, thus completing the merging of the first photovoltaic module frame 1 and the second photovoltaic module frame 2. This makes the separation and merging of the first photovoltaic module frame 1 and the second photovoltaic module frame 2 very convenient, bringing convenience to the maintenance work of maintenance personnel.

[0025] Example 2: Based on Example 1, in order to enable the slider 4 to automatically slide to the other end of the slide groove 3 after the limiting structure is released, a spring groove 9 is provided on the inner wall of the slide groove 3, and a push spring 10 is provided in the spring groove 9. One end of the push spring 10 extending out of the spring groove 9 abuts against the surface of the slider 4.

[0026] In the initial state, the slider 4 is located at one end of the slide groove 3 where the spring groove 9 is provided. The push spring 10 in the spring groove 9 is in a compressed state and abuts against the surface of the slider 4. When the slide groove 3 releases the limit on the slider 4, the push spring 10 pushes the slider 4 to the other end of the slide groove 3 under its own elasticity, thereby achieving the purpose of making the slider 4 automatically slide to the other end of the slide groove 3 after the limit structure is released.

[0027] Example 3: Based on Example 2, in order to make the slider 4 only move in a straight line, one end of the guide rod 7 is fixed on the inner wall of the groove 3 away from the spring groove 9, and the other end of the guide rod 7 is fixed on the inner wall of the spring groove 9. A guide hole 8 is opened on the surface of the slider 4, and the guide rod 7 is movably inserted into the guide hole 8. The groove 3 is a rectangular groove structure, and the slider 4 is a rectangular block structure.

[0028] Under the action of the guide rod 7 and the guide hole 8, the slider 4 can only move along the guide rod 7. At the same time, due to the rectangular groove structure of the slide groove 3 and the rectangular block structure of the slider 4, the slider 4 cannot rotate, thus enabling the slider 4 to only move in a straight line along the guide rod 7 in the slide groove 3.

[0029] Example 4: Based on Example 3, in order to achieve the limiting between the slide groove 3 and the slider 4, a limiting structure is provided between the slide groove 3 and the slider 4. The limiting structure includes: a limiting groove 11, which is formed on the surface of the slider 4; a limiting rod mounting groove 12 is formed on the inner wall of the slide groove 3; one end of a limiting rod 13 is movably inserted into the limiting rod mounting groove 12; and the other end of the limiting rod 13 is movably inserted into the limiting groove 11. The limiting rod 13 has a circular rod structure. A limiting spring 14 is fixed between one end of the limiting rod 13 extending into the limiting rod mounting groove 12 and the inner wall of the limiting rod mounting groove 12. A pull rod hole 15 is opened on the surface of the first photovoltaic module frame 1. The pull rod hole 15 is connected to the limiting rod mounting groove 12. A pull rod 16 is movably inserted into the pull rod hole 15. The pull rod 16 has a "T" shaped round rod structure. The bottom end of the pull rod 16 extends into the limiting rod mounting groove 12 and is fixed on the surface of the limiting rod 13. The top end of the pull rod 16 extends out from the pull rod hole 15.

[0030] One end of the limiting rod mounting groove 12 is inserted into the limiting groove 11 opened on the surface of the slider 4, and the other end of the limiting rod mounting groove 12 is opened in the limiting rod mounting groove 12 opened on the inner wall of the slide groove 3, thereby limiting the slide groove 3 to the slider 4. When it is necessary to release the limit, simply pull the pull rod 16 upward. The pull rod 16 extends a further distance from the pull rod hole 15, driving the limiting rod 13 upward, so that the limiting rod 13 exits from the limiting groove 11, thereby releasing the limitation of the slide groove 3 to the slider 4. When it is necessary to restore the limitation of the slide groove 3 to the slider 4, pull the pull rod 16 upward again. Pull rod 16 drives limit rod 13 to move upward, so that limit rod 13 is fully retracted into limit rod mounting groove 12. The movement of limit rod 13 compresses limit spring 14. Then, the connecting rod 5 is moved, so that the connecting rod 5 drives slider 4 to move back into the slide groove 3 near the end of spring groove 9. At this time, limit groove 11 is aligned with limit rod mounting groove 12. Finally, pull rod 16 is released, and limit spring 14 pushes one end of limit rod 13 back into limit groove 11 under its own elasticity. The other end of limit rod 13 stays in limit rod mounting groove 12, thus restoring the limit of slide groove 3 on slider 4.

[0031] In actual use, when maintenance of the first photovoltaic module frame 1 and the second photovoltaic module frame 2 is not required, the limiting structure limits the slider 4 to one end of the slide groove 3. At this time, the two sets of sliders 4 are located in the slide groove 3 in a direction away from each other. One end of the "L"-shaped connecting rod 5 is inserted into the connecting sleeve 6. Through the action of the connecting rod 5 and the connecting sleeve 6, the first photovoltaic module frame 1 and the second photovoltaic module frame 2 can rotate relative to each other. When maintenance of the first photovoltaic module frame 1 and the second photovoltaic module frame 2 is required and it is necessary to separate the first photovoltaic module frame 1 and the second photovoltaic module frame 2, the distance between the slide groove 3 and the slider 4 is released. The limiting structure allows the two sets of sliders 4 to automatically move closer to each other, causing the two sets of connecting rods 5 to disengage from the two sets of connecting sleeves 6. This facilitates the separation of the first photovoltaic module frame 1 and the second photovoltaic module frame 2. After maintenance, the two sets of connecting sleeves 6 are aligned with the two sets of connecting rods 5, and the two sets of sliders 4 are slid away from each other, restarting the limiting structure. This allows the two sets of connecting rods 5 to re-insert into the two sets of connecting sleeves 6 and maintain the insertion state, thus completing the merging of the first photovoltaic module frame 1 and the second photovoltaic module frame 2. This allows the first photovoltaic module frame 1 and the second photovoltaic module frame 2 to be reassembled. The disassembly and merging of the frame 2 is very convenient, bringing convenience to the maintenance work of the inspection and maintenance personnel; In the initial state, the slider 4 is located at one end of the slide groove 3 where the spring groove 9 is opened. The push spring 10 in the spring groove 9 is in a compressed state and abuts against the surface of the slider 4. When the slide groove 3 releases the limit on the slider 4, the push spring 10 pushes the slider 4 to the other end of the slide groove 3 under its own elastic action, thereby achieving the purpose of letting the slider 4 automatically slide to the other end of the slide groove 3 after the limit structure is released; Under the action of the guide rod 7 and the guide hole 8, the movement direction of the slider 4 can only be along the guide rod 7, and at the same time, due to the rectangular groove structure of the slide groove 3 and The rectangular block structure of slider 4 prevents it from rotating, thus allowing slider 4 to move linearly along guide rod 7 within slide groove 3. One end of limit rod mounting groove 12 is inserted into limit groove 11 on the surface of slider 4, and the other end of limit rod mounting groove 12 is in limit rod mounting groove 12 on the inner wall of slide groove 3, thereby limiting slide groove 3 to slider 4. When it is necessary to release the limit, simply pull rod 16 upwards. Pull rod 16 extends further from pull rod hole 15, causing limit rod 13 to move upwards and exit from limit groove 11, thus releasing slide groove 3 from limiting slider 4.When it is necessary to restore the limiting position of slide 3 on slider 4, pull rod 16 is pulled upward again. Pull rod 16 drives limiting rod 13 upward, causing limiting rod 13 to fully retract into limiting rod mounting groove 12. The movement of limiting rod 13 compresses limiting spring 14. Then, connecting rod 5 is moved, causing connecting rod 5 to move slider 4 back into slide 3 near spring groove 9. At this time, limiting groove 11 is aligned with limiting rod mounting groove 12. Finally, pull rod 16 is released. Under its own elasticity, limiting spring 14 pushes one end of limiting rod 13 back into limiting groove 11, while the other end of limiting rod 13 remains in limiting rod mounting groove 12, thus restoring the limiting position of slide 3 on slider 4.
