Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and in particular to an auxiliary structure for a solar panel system. Background Technology

[0002] Prefabricated shipping containers are modular building units converted from standard shipping containers, combining transportation and architectural functions. They are generally used in construction sites, oil field exploration, and cultural tourism real estate. When used as buildings, prefabricated shipping containers can be equipped with solar panel systems to provide electricity to the interior of the container.

[0003] Solar panel systems typically have two states. When power is needed to supply electricity to the prefabricated housing container, the solar panels need to be fully unfolded, i.e., in the working state. When power is not needed to supply electricity to the prefabricated housing container, or when the prefabricated housing container needs to be moved, the solar panels can be retracted and folded into the unused state, or the retracted solar panels can be moved into the prefabricated housing container for transportation.

[0004] In traditional technologies, solar panel systems typically include a linkage mechanism and a solar panel connected to the mechanism. To activate the solar panel, the linkage mechanism is driven to lift it, bringing its surface to a predetermined angle with sunlight. Considering the limited area of ​​a single solar panel, in some scenarios, two stacked solar panels can be designed, each driven by a linkage structure, to reach a specific angle, thereby improving energy conversion efficiency to some extent.

[0005] However, the increased number of solar panels leads to a significant increase in the driving force required by the linkage mechanism to move the solar panels. At the same time, in the initial stage of solar panel deployment, the component of the driving force in the direction of solar panel movement is relatively small, further increasing the difficulty of driving the solar panels.

[0045] Figure 7 for Figure 6 A magnified view of part A in the diagram. Detailed Implementation

[0046] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0047] See Figure 1 This is a schematic diagram of the solar panel system provided in this application embodiment in an unused state; see also Figure 2 This is a schematic diagram of the solar panel system provided in the embodiment of this application in its usage state.

[0048] Depend on Figure 1 and Figure 2 It is understood that, in some embodiments, the solar panel system may include a base frame assembly 100, a first solar panel 200, a second solar panel 300, a transmission bracket 400, a transmission assembly 500, a fixing assembly 600, and a drive assembly 700.

[0049] The base frame assembly 100 provides support for other components and protects them when the solar panel system is not in use or is being moved. The base frame assembly can be made of high-strength steel, angle iron, or other materials to ensure effective support.

[0050] The first solar panel 200 and the second solar panel 300 are linked to the transmission bracket 400 and the transmission assembly 500, respectively. The transmission assembly 500 is driven by the drive assembly 700. The drive assembly 700 is connected to the transmission assembly 500 and provides driving force. When the solar panel system switches from an unused state to an active state, the drive assembly 700 drives the transmission assembly 500 to move, thereby causing the transmission assembly 500 to move the first solar panel 200 and the second solar panel 300 to move to both sides. Due to the limiting effect of the transmission bracket 400, the first solar panel 200 and the second solar panel 300 will respectively undergo a process of unfolding to both sides, eventually reaching a fully unfolded state (e.g., ...). Figure 2 ).

[0051] Conversely, when the solar panel system switches from an active state to an inactive state, the drive component 700 drives the transmission component 500 to move in the opposite direction. This causes the transmission component 500 to move the first solar panel 200 and the second solar panel 300 towards the center. Due to the limiting effect of the transmission bracket 400, the first solar panel 200 and the second solar panel 300 will respectively undergo a process of stacking towards the center, ultimately reaching the initial state (e.g., ...). Figure 1 ).

[0052] In some embodiments, when the solar panel system is not in use, it can be moved as a whole into a container for transportation. In order to enable a container to transport multiple sets of solar panel systems at the same time, a fixing component 600 can be set up. The fixing component 600 can fix the solar panel system to the container, and can also fix the stacked solar panel systems by means of its configuration with the bottom frame component 100.

[0053] Since the deployment of solar panels requires the coordinated operation of the drive component 700 and the transmission component 500, in the initial stage of the deployment process, the driving force needs to simultaneously bear the weight of two solar panels. Furthermore, the initial component of the driving force in the direction of solar panel movement is relatively small, further increasing the difficulty of driving the solar panels. Therefore, a larger driving force is necessary to meet the deployment requirements of the solar panels. If this operation is performed manually, it is difficult to achieve the desired result. If electric drive is used, the requirements for the equipment are higher, increasing the overall cost of the equipment.

[0054] To address the initial difficulty in opening dual-support solar panels in related technologies, this application provides an assistive structure for a solar panel system. By adding this structure to the solar panel system, the problem of insufficient driving force causing the solar panel to be difficult to unfold smoothly can be effectively solved.

[0055] See Figure 3 This is a schematic diagram of the auxiliary structure of the solar panel system provided in the embodiments of this application.

[0056] like Figure 3 As shown, the assist structure provided in this application includes:

[0057] Base plate 10; Base plate 10 is used to install and support other components, ensuring the stability and functionality of the entire auxiliary structure. Base plate 10 can be made of high-strength, corrosion-resistant materials to adapt to complex and variable outdoor environmental conditions. Base plate 10 can be fixed to the base frame assembly 100 by bolting or welding.

[0058] A driving component 20 is disposed on the upper surface of the base plate 10, and the driving component 20 is provided with a first driving end; in this embodiment of the application, the driving component 20 can be a motor, cylinder, hydraulic cylinder or other equipment, or it can be a manually driven structure composed of mechanical parts.

[0059] The first transmission member 30 is disposed on the side of the driving member 20 where the first driving end is provided, and is laid along a first direction, which is the direction in which the first driving end drives the first transmission member 30 to move. In this embodiment, the first transmission member 30 is used to connect the first solar panel so that the first transmission member 30 drives the first solar panel to unfold away from the base plate 10 under the drive of the first driving end.

[0060] It should be noted that, in the embodiments of this application, a solar panel can be driven by a separate set of driving components and transmission components, or multiple solar panels can be driven by a single driving component, and there is no limitation on this.

[0061] The assisting component 40 is disposed on one side of the first transmission component 30 along the first direction. When the first solar panel is not unfolded, the assisting component 40 is used to provide an elastic force to the first transmission component 30 in the first direction.

[0062] In this embodiment, the working principle of the assisting component 40 is as follows: In the initial stage of solar panel deployment, due to the gravity of the solar panel, the first transmission component 30 needs to overcome significant resistance to begin movement. At this time, the assisting component 40 provides an elastic force in a first direction to the first transmission component 30. This elastic force assists the first transmission component 30 in overcoming the initial resistance, making it easier for the first solar panel to begin the deployment process. As the first solar panel gradually unfolds, the driving force provided by the driving component 20 gradually increases, while the elastic force of the assisting component 40 gradually decreases until the elastic force of the assisting component 40 is zero or close to zero when the first solar panel is fully unfolded. Thus, the assisting component 40 provides additional assistance in the initial stage of solar panel deployment, reducing the driving force requirement on the driving component 20, making the entire solar panel system deployment process smoother and more efficient.

[0063] See Figure 4 This is a schematic diagram of the internal structure of the solar panel system in its deployed state in an embodiment of this application; see also... Figure 5 ,for Figure 4 Top view of the embodiment shown;

[0064] It should be noted that, for ease of description, in Figures 4-5 In the middle, some components were selectively hidden, for example Figure 5 The first sleeve 41 is partially obscured to show the elastic element 42; Figure 4 Components that might obscure the described parts have been omitted. Therefore, it should not be interpreted as... Figure 4 and Figure 5 The structure shown is substantially different from the assist structure provided in the embodiments of this application.

[0065] like Figure 4 and Figure 5 It is understood that in some embodiments, the first transmission member 30 includes an end plate 31; the end plate 31 extends toward the assist member 40 to form a first column 311;

[0066] The assistive component 40 includes:

[0067] First sleeve 41; the first sleeve 41 is fixed to the upper surface of the base plate 10; one end of the first sleeve 41 is a fixed end, and the other end is provided with an opening;

[0068] An elastic element 42 is disposed inside the first sleeve 41; when the first solar panel is not unfolded, the first column 311 on the first transmission member extends into the opening in the second direction, and the elastic element 42 elastically abuts against the first column 311 so that the elastic element 42 provides an elastic force in the first direction to the first column 311; the second direction is the opposite direction of the first direction.

[0069] In some embodiments, the elastic element 42 can be a spring. When the first column 311 enters the opening of the first sleeve 41, it continues to move in the direction of compressing the spring. The spring stores elastic potential energy. Due to the gravity of the solar panel, the first column 311 will not be pushed back out of the first sleeve 41 by the elastic potential energy. When the solar panel needs to be deployed, the elastic potential energy can offset part of the solar panel's gravity. At this time, applying a certain driving force makes it easier to start the solar panel. As the angle of the solar panel changes, the component of the driving force in the direction of solar panel movement gradually increases, and the assistance provided by the spring is no longer needed. At this time, the first column 311 can be completely separated from the spring (e.g., Figure 4 The spring returns to its unforced state.

[0070] In some embodiments, see Figure 4 and Figure 5 The first transmission component 30 includes:

[0071] The slide rail 32 is fixed to the upper surface of the base plate 10; the slide rail 32 is laid along the first direction;

[0072] The slider 33 is slidably connected to the slide rail 32; the end of the slider 33 away from the drive member 20 is provided with the end plate 31; the end of the slider 33 close to the drive member 20 is connected to the first drive end.

[0073] In this embodiment, the first direction refers to the direction in which the slider 33 moves along the slide rail 32, which is also the direction in which the first transmission member 30 moves. In actual application, the end plate 31 can be hinged to one side of the solar panel. When the slider 33 moves away from the drive member 20 along the slide rail 32, the end plate 31 moves outward with the slider 33, thereby driving the solar panel to move outward. At the same time, the angle between the solar panel and the end plate changes, and the solar panel rotates on the other side with the hinge axis with the end plate as the center, that is, it unfolds outward.

[0074] See Figure 6 The diagram shows the structure of the base plate in some embodiments of the assist structure provided in this application.

[0075] In some embodiments, in order to improve the stability of the transmission, such as Figure 6 As shown, the slide rail 32 may include:

[0076] The first slide rail 321 and the second slide rail 322 are laid sequentially along the first direction. The two slide rails increase the total length of the slide rail 32, ensuring the stability of the sliding member 33 during movement.

[0077] See Figure 7 ,for Figure 6 A magnified view of part A in the diagram;

[0078] In some embodiments, such as Figure 7 As shown, the first slide rail 321 or the second slide rail 322 includes:

[0079] The first curved surface 3211 forms a through hole for the sliding member 33 to pass through; correspondingly, the sliding member 33 should be provided with a cylindrical structure adapted to the size of the through hole.

[0080] At least a portion of the first curved surface 3211 includes a sliding surface 3212, on which a plurality of rolling balls 3213 are evenly distributed, and the rolling balls 3213 are in rolling contact with the slider 33.

[0081] In this embodiment, the rolling balls 3213 reduce the frictional resistance between the slider 33 and the slide rail 32, making the movement of the slider 33 on the slide rail 32 smoother. Simultaneously, since the rolling balls 3213 are evenly distributed on the sliding surface 3212, the stability and balance of the slider 33 during movement are ensured, preventing the slider 33 from skewing or jamming due to uneven force. Furthermore, the rolling balls 3213 extend the service life of the slide rail 32 and the slider 33, reduce wear and tear caused by friction, and lower maintenance costs.

[0082] In some embodiments, see Figure 4 and Figure 5 The driving component may include a worm gear device 21, which is connected to the first transmission component 30 via a threaded rod 22; the base plate 10 is provided with a first limiting block 11 and a second limiting block 12, and the threaded rod 22 is rotatably connected to the first limiting block 11 and the second limiting block 12 respectively.

[0083] The worm gear device 21 is also connected to a drive rod 23, which is arranged along a third direction and is perpendicular to the first direction. The worm gear device 21 can convert the rotational motion input by the drive rod 23 along the third direction into rotational motion along the first direction.

[0084] The first transmission component 30 further includes:

[0085] A slider 34 is disposed between the first limiting block 11 and the second limiting block 12. The slider 34 is connected to the sliding member 33. The threaded rod 22 passes through the slider 34 and is threadedly connected to the slider 34. When the threaded rod 22 rotates under the drive of the driving member 20 (worm gear device 21), the slider 34, due to the limitation of the rotation direction, will generate a linear motion along the threaded rod direction, approaching the first limiting block 11 or the second limiting block 12, thereby realizing the driving of the first transmission member 30 along the first direction.

[0086] In this embodiment, the first limiting block 11 and the second limiting block 12 respectively provide a limiting function for the slider 34 to prevent the solar panel from unfolding at too large an angle and becoming difficult to retract, or to prevent residual stress on other components. For example, when the slider 34 moves to contact the first limiting block 11, it can be considered that the solar panel is in a just-tightened state; when the slider 34 moves to contact the second limiting block 12, it can be considered that the solar panel is at its maximum unfolding angle.

[0087] It should be noted that in actual use, the solar panel is not always in the maximum unfolded angle state depending on the angle of the light. Therefore, the slider 34 does not necessarily have to be in contact with the second limiting block 12. It can also stay at a certain position between the first limiting block 11 and the second limiting block 12 under the support of the driving force.

[0088] See Figure 3 In some embodiments, it also includes:

[0089] The cover 50 is connected to the base plate 10. When the first solar panel is not unfolded, a receiving space is formed between the cover 50 and the base plate 10 to accommodate the first transmission member 30.

[0090] In this embodiment, the cover 50 provides protection for the first transmission component 30, preventing it from being interfered with or damaged by the external environment. Simultaneously, the accommodating space formed between the cover 50 and the base plate 10 effectively prevents debris or dust from entering the transmission system, ensuring the normal operation of the first transmission component 30. The cover 50 can be connected to the base plate 10 via bolts, snap-fit ​​connections, or other fixing methods to ensure its stability and reliability. When the solar panel system is not in use, the cover 50 can be tightly fitted onto the base plate 10, forming a closed accommodating space.

[0091] In some embodiments, to further improve the stability of the solar panel system, a locking structure can be added to the original structure. For example, the first limiting block 11 includes:

[0092] First locking part (not shown in the figure);

[0093] When the first solar panel is not deployed, the slider 34 abuts against the first limiting block 11, and the first limiting block 11 and the slider 34 form a self-locking structure through the first locking part.

[0094] It should be noted that, in the embodiments of this application, the form of the first locking part is not limited to one type. For example, a magnetically attractive permanent magnet and an iron block are respectively provided on the slider 34 and the first limiting block 11, or a snap-locking, elastic locking, or other structure is provided on the opposite surfaces of the two, all of which can achieve the self-locking effect described in this embodiment.

[0095] In some embodiments, the second limiting block 12 includes:

[0096] Second locking part (not shown in the figure);

[0097] When the first solar panel is fully extended, the slider 34 abuts against the second limiting block 12, and the second limiting block 12 and the slider 34 form a self-locking structure through the second locking part.

[0098] The form of the second locking part can be the same as that of the first locking part, and will not be described in detail here.

[0099] In some embodiments, a single driver 20 can drive two solar panels simultaneously, such as... Figure 3 The driving component 20 is further provided with a second driving end, which is disposed on two opposite sides of the driving component, along with the first driving end; the assist structure further includes:

[0100] The second transmission member 60 is disposed on the side of the driving member 20 where the second driving end is provided, and is laid along the second direction, which is the direction in which the second driving end drives the second transmission member 60 to move; the second transmission member 60 is used to connect the second solar panel, so that the second transmission member 60 drives the second solar panel to unfold away from the base plate 10 under the drive of the second driving end; the structure of the second transmission member 60 is the same as the structure of the first transmission member 30.

[0101] The technical effects of the second transmission component 60 during use can be found in the description of the first transmission component 30 mentioned above, and will not be repeated here.

[0102] As can be seen from the above technical solution, this application provides additional assistance during the initial deployment of the solar panel by setting an assist structure, thereby reducing the driving force requirements of the driving components. This assist structure includes components such as a base plate, a driving component, a first transmission component, and an assist component. These components work together to achieve smooth deployment of the solar panel. Simultaneously, by setting structures such as slide rails and rolling balls, frictional resistance is reduced, improving the stability and balance of the transmission. Furthermore, by setting structures such as limit blocks and locking parts, the stability and reliability of the solar panel system are further improved. In summary, the assist structure for the solar panel system provided by this application has advantages such as simple structure, convenient operation, and stable reliability, and can be widely used in various occasions requiring solar panel deployment.
