Detailed Implementation

[0067] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0068] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0069] The following describes in detail, with reference to Figures 1-28, an embodiment of the present application, a solar photovoltaic panel assembly 10, a vehicle 100 including the solar photovoltaic panel assembly 10, and an electrical device including the solar photovoltaic panel assembly 10.

[0070] The solar photovoltaic panel module 10 according to this application can be applied not only to vehicles 100, such as RVs, but also to other electrical devices as needed, such as rooftops. For ease of description, the structure of the solar photovoltaic panel module 10 will be described below using the application of the solar photovoltaic panel module 10 to a vehicle 100 as an example.

[0071] Referring to Figures 1-3, 5, 7, and 11, the solar photovoltaic panel assembly 10 according to an embodiment of this application includes: a support frame 1, a main photovoltaic panel 2, and a secondary photovoltaic panel 3.

[0072] The support frame 1 is a split frame, comprising a first frame 11 and a second frame 12, which are arranged opposite to each other. The main photovoltaic panel 2 is located between the first frame 11 and the second frame 12, which are connected by the main photovoltaic panel 2. The auxiliary photovoltaic panel 3 is located between the first frame 11 and the second frame 12, and can slide along the first frame 11 and / or the second frame 12 to a storage position with the largest overlap area with the main photovoltaic panel 2 in the thickness direction, and to an unfolded position relative to the main photovoltaic panel 2.

[0073] In other words, a photovoltaic panel installation space is formed between the first frame 11 and the second frame 12. Both the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are located within the photovoltaic panel installation space. One end of the main photovoltaic panel 2 (end F3 as shown in Figure 2) is connected to the first frame 11, and the other end of the main photovoltaic panel 2 (end F4 as shown in Figure 2) is connected to the second frame 12. The first frame 11 and the second frame 12 are connected only by the main photovoltaic panel 2, without relying on other frames for connection. Traditional support frames adopt a structure that completely surrounds the photovoltaic panel, which increases the cost and installation difficulty of the solar photovoltaic panel module. To reduce costs and installation difficulty, the structure of the support frame 1 is optimized in this application. The main photovoltaic panel 2 is used as a connecting frame to connect the main photovoltaic panel 2 to the first frame 11 and the main photovoltaic panel 2 to the second frame 12. When it is necessary to install the solar photovoltaic panel module 10 on the substrate surface, it is only necessary to fix the first frame 11 and the second frame 12 to the substrate surface.

[0074] The secondary photovoltaic panel 3 can slide along the first frame 11 and / or the second frame 12 to a stowed position and an unfolded position. The position of the secondary photovoltaic panel 3 shown in Figures 1 and 11 is the stowed position, and the position of the secondary photovoltaic panel 3 shown in Figures 2-3, 5, and 7 is the unfolded position. The position shown in Figures 2 and 7 is the partially unfolded position, and the position shown in Figures 3 and 5 is the fully unfolded position. Optionally, the secondary photovoltaic panel 3 can slide only along the first frame 11 to the stowed position and the unfolded position, or it can slide only along the second frame 12 to the stowed position and the unfolded position, or it can slide simultaneously along both the first frame 11 and the second frame 12 to the stowed position and the unfolded position.

[0075] The first frame 11 and the second frame 12 serve as support components for the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3, providing fixed support for them. Simultaneously, the main photovoltaic panel 2 connects the first frame 11 and the second frame 12, making the solar photovoltaic module 10 a unified whole, facilitating its overall handling, assembly, and disassembly. The solar photovoltaic module 10 of this application has a stable and reliable structure, long lifespan, and good performance.

[0076] The main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are stacked along the thickness direction, that is, the large surface area of ​​the main photovoltaic panel 2 and the large surface area of ​​the auxiliary photovoltaic panel 3 are arranged opposite each other. This makes reasonable use of the thickness direction space of the support frame 1, so that the overall thickness dimension of the solar photovoltaic panel assembly 10 is small and does not occupy too much height space. For example, when the solar photovoltaic panel assembly 10 is installed on the body 20 of the vehicle 100, it will not significantly increase the height dimension of the vehicle 100, so that the solar photovoltaic panel assembly 10 has little impact on the vehicle 100's passability. The thickness direction of the support frame 1, the main photovoltaic panel 2, and the auxiliary photovoltaic panel 3 is the F5-F6 direction shown in Figures 1, 3, 5, 7, and 11.

[0077] Optionally, the main photovoltaic panel 2 has a plate-like structure, and the large surface of the main photovoltaic panel 2 can be perpendicular to the thickness direction of the supporting frame 1. The main photovoltaic panel 2 is fixed to the first frame 11 and the second frame 12, that is, the main photovoltaic panel 2 and the first frame 11 and the second frame 12 are set to a non-sliding structure to reduce the number of sliding parts in the solar photovoltaic panel module 10.

[0078] Similarly, the auxiliary photovoltaic panel 3 has a plate-like structure, and the large surface of the auxiliary photovoltaic panel 3 can be perpendicular to the thickness direction of the supporting frame 1.

[0079] When the secondary photovoltaic panel 3 is in the retracted position, as shown in Figures 1 and 11, the overlap area between the secondary photovoltaic panel 3 and the main photovoltaic panel 2 in the thickness direction of the supporting frame 1 is the largest, that is, the secondary photovoltaic panel 3 and the main photovoltaic panel 2 can overlap to the maximum extent. When the secondary photovoltaic panel 3 is in the unfolded position, the secondary photovoltaic panel 3 slides outward relative to the main photovoltaic panel 2. Specifically, the secondary photovoltaic panel 3 can slide outward partially relative to the main photovoltaic panel 2, such as the partially unfolded position shown in Figures 2 and 7; the secondary photovoltaic panel 3 can also slide outward completely relative to the main photovoltaic panel 2, such as the fully unfolded position shown in Figures 3 and 5.

[0080] As the secondary photovoltaic panel 3 slides outward relative to the primary photovoltaic panel 2, the overlap area between the secondary photovoltaic panel 3 and the primary photovoltaic panel 2 in the thickness direction of the supporting frame 1 gradually decreases as the degree of expansion increases. As the secondary photovoltaic panel 3 retracts inward relative to the primary photovoltaic panel 2, the overlap area between the secondary photovoltaic panel 3 and the primary photovoltaic panel 2 in the thickness direction of the supporting frame 1 gradually increases as the degree of expansion decreases.

[0081] The area of ​​the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 that receives sunlight is the power generation area. When the auxiliary photovoltaic panel 3 is in the extended position, the total power generation area of ​​the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 increases, and the power generation increases accordingly. When the auxiliary photovoltaic panel 3 is in the retracted position, the total power generation area of ​​the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 decreases, and the power generation decreases accordingly. By sliding the auxiliary photovoltaic panel 3 outward relative to the main photovoltaic panel 2 to the extended position, the power generation area of ​​the solar photovoltaic panel module 10 can be expanded, and the power generation capacity of the solar photovoltaic panel module 10 can be increased, thereby increasing the power generation to meet the user's electricity demand.

[0082] According to the embodiments of this application, the solar photovoltaic panel assembly 10 uses the main photovoltaic panel 2 to connect the first frame 11 and the second frame 12, eliminating the need for a separate frame to connect the first frame 11 and the second frame 12. This helps to reduce the total weight of the supporting frame 1 and achieves a lightweight design of the overall structure of the solar photovoltaic panel assembly 10. When the solar photovoltaic panel assembly 10 is applied to a vehicle 100 or other electrical devices, the energy consumption of the vehicle 100 will not increase significantly.

[0083] In some embodiments of this application, the secondary photovoltaic panel 3 is located on the side of the main photovoltaic panel 2 facing the mounting substrate. When the secondary photovoltaic panel 3 is in the retracted position, the main photovoltaic panel 2 can provide maximum shading for the secondary photovoltaic panel 3; when the secondary photovoltaic panel 3 is in a partially extended position, the main photovoltaic panel 2 can provide partial shading for the secondary photovoltaic panel 3. The shading effect of the main photovoltaic panel 2 can prevent debris from falling into the sliding track of the secondary photovoltaic panel 3, thereby protecting the sliding movement of the secondary photovoltaic panel 3 and making the sliding of the secondary photovoltaic panel 3 more stable and smooth. For example, ...

[0084] Specifically, there is one auxiliary photovoltaic panel 3. The auxiliary photovoltaic panel 3 and the main photovoltaic panel 2 together form a two-layer photovoltaic panel structure, which does not significantly increase the thickness of the solar photovoltaic panel assembly 10. When the solar photovoltaic panel assembly 10 is installed on the vehicle body 20 of the vehicle 100, it does not significantly increase the height dimension of the vehicle 100, so that the solar photovoltaic panel assembly 10 has little impact on the passability of the vehicle 100. The thickness direction of the solar photovoltaic panel assembly 10 is the same as the thickness direction of the support frame 1, which is the F5-F6 direction shown in Figures 1, 3, 5, 7, and 11.

[0085] In some embodiments, the solar photovoltaic panel assembly 10 is applied to a vehicle 100. Specifically, the solar photovoltaic panel assembly 10 is mounted on the vehicle body 20 of the vehicle 100, and the auxiliary photovoltaic panel 3 is located on the side of the main photovoltaic panel 2 facing the vehicle body 20. When the vehicle 100 is in motion, the additional auxiliary photovoltaic panel 3 can be hidden below the uppermost main photovoltaic panel 2 to improve the driving safety of the vehicle 100. When the vehicle 100 is stationary, the hidden auxiliary photovoltaic panel 3 can be extended through the drive component 4 to increase the power generation capacity.

[0086] In addition, designing the solar photovoltaic panel module 10 as a two-layer structure including the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 allows for a suitable size and weight to meet the additional power generation needs, resulting in better practicality. Furthermore, the two-layer design does not significantly increase the height.

[0087] In one embodiment, the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are constructed as a two-layer structure. The main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are solar photovoltaic panels of the same size. The power of the main photovoltaic panel 2 is 195W, the power of the auxiliary photovoltaic panel 3 is 195W, and the total power of the solar photovoltaic panel module 10 is close to 400W.

[0088] Of course, without considering the above factors, in some other embodiments of this application, there may be multiple auxiliary photovoltaic panels 3, such as two, three or more, so that users can slide the auxiliary photovoltaic panels 3 to the unfolded position as needed to increase the power generation area of ​​the solar photovoltaic panel module 10.

[0089] In some embodiments of this application, the solar photovoltaic panel assembly 10 further includes a drive member 4, which is fixedly mounted on the main photovoltaic panel 2 and is used to drive the secondary photovoltaic panel 3 to slide. In some embodiments, the drive member 4 is an electric cylinder to push the secondary photovoltaic panel 3 outward relative to the main photovoltaic panel 2, or pull the secondary photovoltaic panel 3 inward relative to the main photovoltaic panel 2. By providing the drive member 4, the movement of the secondary photovoltaic panel 3 can be electrified, which is beneficial to improving the user experience.

[0090] In some embodiments of this application, referring to Figures 7-8 and 10-17, the driving component 4 is in the form of an electric telescopic rod, and the driving component 4 includes a driving mechanism 41 and a multi-stage telescopic rod 42. The multi-stage telescopic rod 42 includes at least a first-stage telescopic rod 421 and a last-stage telescopic rod 422. The driving mechanism 41 is fixedly installed on the main photovoltaic panel 2. One end of the first-stage telescopic rod 421 is located inside the driving mechanism 41. Adjacent telescopic rods 42 are nested. The last-stage telescopic rod 422 is fixedly connected to the secondary photovoltaic panel 3. The driving mechanism 41 can drive the multi-stage telescopic rod 42 to extend or retract relative to the driving mechanism 41. The drive mechanism 41 includes a drive motor 411 and a telescopic rod storage compartment 414. The drive motor 411 is installed in the internal space of the telescopic rod storage compartment 414. When the multi-stage telescopic rod 42 extends outward relative to the telescopic rod storage compartment 414, the multi-stage telescopic rod 42 pushes the secondary photovoltaic panel 3 to slide outward; when the multi-stage telescopic rod 42 retracts inward relative to the telescopic rod storage compartment 414, the multi-stage telescopic rod 42 pulls the secondary photovoltaic panel 3 inward. The electric telescopic rod 42 automates the sliding action of the secondary photovoltaic panel 3, saving the user's physical effort. Optionally, when the drive motor 411 rotates forward, it can drive the multi-stage telescopic rod 42 to extend outward; when the drive motor 411 rotates in reverse, it can drive the multi-stage telescopic rod 42 to retract inward.

[0091] In some embodiments of this application, the multi-stage telescopic rods 42 are all rod-shaped structures, and the telescopic direction of each stage of the telescopic rod 42 is parallel to the sliding direction of the sub-photovoltaic panel 3. In related technologies, solar photovoltaic panel modules include a main photovoltaic panel and a sub-photovoltaic panel. The sub-photovoltaic panel slides using a traditional electric push rod. The traditional electric push rod includes a single-stage push rod, and the extension direction of the push rod is parallel to the sliding direction of the sub-photovoltaic panel. If a one-meter extension is required, the overall length of the push rod needs to be 20 centimeters longer than the extension distance. This results in a larger frame volume to accommodate the electric push rod, directly increasing the frame size and weight of the finished product, and causing significant difficulties in product installation. If a 700mm extension distance is required, the overall length of the push rod will reach 855mm, meaning that its achievable extension range is smaller than its overall length. In this application, by setting the telescopic rods 42 to be multi-stage, the overall length of the drive component 4 can be shortened. For example, the overall length of the drive component 4 is 690mm, but the extension distance can reach 730mm. In other words, the drive component 4 of this application, due to the multi-stage telescopic rods 42, can achieve a greater extension range than its overall length. Meanwhile, the extension and retraction direction of each telescopic rod 42 is parallel to the sliding direction of the sub-photovoltaic panel 3. This makes the driving force of the telescopic rod 42 on the sub-photovoltaic panel 3 consistent with the sliding direction of the sub-photovoltaic panel 3, making it less likely for the sub-photovoltaic panel 3 to deviate or get stuck, which helps to ensure the smoothness of the sliding of the sub-photovoltaic panel 3.

[0092] Furthermore, the thickness of a traditional electric linear actuator is 40mm, while the thickness of the drive component 4 used in this application is only 25mm, a significant reduction in thickness. Consequently, the drive component 4 used in this application is lighter than that of a traditional electric linear actuator. Comparing the noise levels of a traditional electric linear actuator with those of the drive component 4 used in this application, the drive component 4 operates with significantly less noise.

[0093] In some embodiments of this application, the driving component 4 may be a DC electric telescopic rod, characterized by its long extension, slow rotation speed, large torque, and the ability to achieve forward and reverse rotation through current reversal.

[0094] In some embodiments of this application, referring to Figures 7-8 and 10-13, the drive member 4 is located on the side of the secondary photovoltaic panel 3 facing away from the main photovoltaic panel 2. This allows the main photovoltaic panel 2 and the secondary photovoltaic panel 3 to provide maximum shading for the drive member 4, preventing debris from falling onto it and protecting the telescopic rod 42 from its extension and retraction, resulting in smoother and more stable extension and retraction. The solar photovoltaic panel assembly 10 also includes a first fixed bracket 51 and a second fixed bracket 52. The drive mechanism 41 is fixedly mounted to the main photovoltaic panel 2 via the first fixed bracket 51, and the final-stage telescopic rod 422 is fixedly mounted to the secondary photovoltaic panel 3 via the second fixed bracket 52.

[0095] Referring to Figures 7-9 and 11-12, the first fixed bracket 51 includes a bracket body 511 and a bracket arm 512. The bracket body 511 is fixedly installed on the main photovoltaic panel 2. The bracket arm 512 is connected to the bracket body 511 and extends in the sliding direction of the secondary photovoltaic panel 3. The drive mechanism 41 is provided with a fixing nut 43. The bracket arm 512 is provided with a first bracket hole 513 corresponding to the threaded hole of the fixing nut 43. After the bolt passes through the first bracket hole 513, it is tightened in the threaded hole of the fixing nut 43, thereby realizing the connection and fixation between the first fixed bracket 51 and the drive mechanism 41.

[0096] Optionally, the fixing nut 43 can be placed in the groove on the outer surface of the drive mechanism 41. There can be multiple fixing nuts 43. The groove on the outer surface of the drive mechanism 41 extends in the sliding direction of the sub-photovoltaic panel 3. Multiple fixing nuts 43 are distributed in the sliding direction of the sub-photovoltaic panel 3. The first bracket hole 513 corresponds to the fixing nut 43 one by one, which helps to improve the connection between the first fixing bracket 51 and the drive mechanism 41.

[0097] Referring to Figures 7, 10-11, and 13, the second fixed bracket 52 can be fastened to the sub-photovoltaic panel 3 with bolts. The second fixed bracket 52 has a second bracket hole 521. After the bolt passes through the second bracket hole 521, it is fastened into the threaded hole of the final-stage telescopic rod 422, thereby achieving the connection and fixation between the final-stage telescopic rod 422 and the second fixed bracket 52. Optionally, there can be multiple second bracket holes 521, which helps to improve the connection strength between the final-stage telescopic rod 422 and the second fixed bracket 52.

[0098] In some embodiments of this application, both the main photovoltaic panel 2 and the secondary photovoltaic panel 3 include a photovoltaic frame and a photovoltaic laminated structure. The photovoltaic frame surrounds the photovoltaic laminated structure, which is a laminated structure of tempered glass, EVA (Ethylene-Vinyl Acetate) film, solar cells, and a backsheet. The drive mechanism 41 is fixedly installed on the photovoltaic frame of the main photovoltaic panel 2 via a first fixed bracket 51, and the final stage telescopic rod 422 is fixedly installed on the photovoltaic frame of the secondary photovoltaic panel 3 via a second fixed bracket 52. Specifically, referring to Figures 8 and 9, the main photovoltaic panel 2 includes a main photovoltaic frame 21 and a main photovoltaic laminated structure 22. The main photovoltaic laminated structure 22 is fixedly installed on the main photovoltaic frame 21, and the bracket body 511 is fixedly installed on the main photovoltaic frame 21. Referring to Figure 13, the secondary photovoltaic panel 3 includes a secondary photovoltaic frame 31 and a secondary photovoltaic laminated structure 32. The secondary photovoltaic laminated structure 32 is fixedly installed on the secondary photovoltaic frame 31, and the second fixed bracket 52 is fixedly installed on the secondary photovoltaic frame 31.

[0099] Optionally, the photovoltaic frame is constructed as a circumferentially closed, through-thickness frame structure, with the photovoltaic laminate structure installed within the circumferential space enclosed by the photovoltaic frame. Specifically, the main photovoltaic laminate structure 22 is installed within the circumferential space enclosed by the main photovoltaic frame 21, and the secondary photovoltaic laminate structure 32 is installed within the circumferential space enclosed by the secondary photovoltaic frame 31.

[0100] In some embodiments of this application, the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 have the same structure. Specifically, the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are the same in size and model. When the auxiliary photovoltaic panel 3 is in the fully extended position, the total power generation area of ​​the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 is the largest, which is the power generation area of ​​two photovoltaic panels. When the auxiliary photovoltaic panel 3 is in the stowed position, the total power generation area of ​​the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 is reduced to the power generation area of ​​one photovoltaic panel. When the auxiliary photovoltaic panel 3 is in the extended position, the power generation capacity of the solar photovoltaic panel module 10 can be increased, for example, by 1 to 2 times.

[0101] In some embodiments of this application, the profile thickness of the photovoltaic frame is 1.5mm to 4mm, and the photovoltaic frame is provided with threaded holes. The solar photovoltaic panel assembly 10 also includes photovoltaic fastening bolts, which pass through the first frame 11 or the second frame 12 and are fastened to the threaded holes. Optionally, the profile thickness of the photovoltaic frame can be 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm. Of course, the profile thickness of the photovoltaic frame can also be other values ​​within the range of 1.5mm to 4mm, which will not be listed here. Using a profile thickness of 1.5mm to 4mm for the photovoltaic frame allows for direct machining of threaded holes on the photovoltaic frame without the need for additional nuts, thereby making the installation between the photovoltaic frame and the support frame 1 more convenient. Referring to Figures 18-19, the main photovoltaic frame 21 includes a horizontal support arm 212 and a vertical support arm 213. Both the horizontal support arm 212 and the vertical support arm 213 are provided with main thread holes 211. After the photovoltaic fastening bolt passes through the first frame 11, it is fastened to the corresponding main thread hole 211, thereby completing the connection and fixation between the main photovoltaic frame 21 and the first frame 11.

[0102] Alternatively, the photovoltaic frame can be an aluminum profile, a copper profile, or the like.

[0103] Optionally, the height of the photovoltaic frame is 16mm to 25mm, meaning the dimension of the photovoltaic frame in the thickness direction of the solar photovoltaic panel module 10 is 16mm to 25mm. For example, the height of the photovoltaic frame can be 16mm, 18mm, 20mm, 23mm, or 25mm. Of course, the height of the photovoltaic frame can also be other values ​​within the range of 16mm to 25mm, which will not be listed here. Compared to the thickness of traditional photovoltaic panels of 35mm or more, the height of the photovoltaic frame in this application is significantly reduced, which is beneficial for reducing the overall thickness of the photovoltaic panel and thus facilitates the lightweight design of the solar photovoltaic panel module 10.

[0104] According to the embodiments of this application, the drive component 4 is installed in the middle position between the first frame 11 and the second frame 12, thereby preventing the auxiliary photovoltaic panel 3 from getting stuck during sliding, which would cause displacement and damage to the telescopic rod 42 or the auxiliary photovoltaic panel 3.

[0105] In some embodiments of this application, the first frame 11, the second frame 12, and the photovoltaic frame are all aluminum alloy frames. This gives the first frame 11, the second frame 12, and the photovoltaic frame good strength and light weight, enabling a lightweight design of the solar photovoltaic module 10. Furthermore, using aluminum alloy material prevents problems such as rusting during prolonged use.

[0106] The aluminum alloy frame allows for easy assembly and disassembly, resulting in a small package size, low weight, and low transportation costs. Both the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are aluminum alloy frame glass structures, offering strong load-bearing capacity, robust structure, high hardness, and a longer lifespan. Since conventional 195W photovoltaic frames are thicker, reaching a height of 35mm, which increases the overall product height, the solar photovoltaic panel module 10 of this application features a redesigned photovoltaic frame, reducing its thickness to 23mm while maintaining the overall strength of the photovoltaic panel.

[0107] In some embodiments of this application, the solar photovoltaic panel assembly 10 further includes a junction box 53, which is fixed to a first fixing bracket 51. The junction box 53 is provided with a connector 55, and the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are adapted to be connected to the corresponding connector 55. Referring to Figures 1-2 and 5-6, the connector 55 includes a positive connector 551 and a negative connector 552. The positive connector 551 includes a main photovoltaic positive connector 5511 and a secondary photovoltaic positive connector 5512. The negative connector 552 includes a main photovoltaic negative connector 5521 and a secondary photovoltaic negative connector 5522. The main photovoltaic panel 2 has a main photovoltaic positive line 23 and a main photovoltaic negative line 24. The secondary photovoltaic panel 3 has a secondary photovoltaic positive line 33 and a secondary photovoltaic negative line 34. The main photovoltaic positive line 23 is connected to the main photovoltaic positive connector 5511, the main photovoltaic negative line 24 is connected to the main photovoltaic negative connector 5521, the secondary photovoltaic positive line 33 is connected to the secondary photovoltaic positive connector 5512, and the secondary photovoltaic negative line 34 is connected to the secondary photovoltaic negative connector 5522. Specifically, the junction box 53 is fixed to the bracket body 511 of the first fixed bracket 51, and the junction box 53 is fixed as one piece to the first fixed bracket 51 and fixed to the main photovoltaic frame 21.

[0108] The junction box 53 and connector 55 are used to consolidate the wiring. This simplifies wiring for users by centralizing the connections at the junction box 53, improving efficiency. It also prevents users from manually routing the wiring, avoiding tangled wires that could cause product malfunctions. The junction box 53 gathers the wiring from multiple photovoltaic panels, greatly simplifying electrical connections between them. Optionally, the connector 55 is a standard MC4 connector. The main photovoltaic positive wire 23, main photovoltaic negative wire 24, auxiliary photovoltaic positive wire 33, and auxiliary photovoltaic negative wire 34 are all MC4 wires. Simply insert the MC4 wires from the photovoltaic panel into the junction box 53 and lock them in place with the MC4 connector (as shown in Figure 6).

[0109] In some embodiments of this application, the solar photovoltaic panel assembly 10 further includes a parallel connector 56, which is used to realize the parallel output of multiple photovoltaic panels, thereby increasing the charging current and meeting different user needs. As shown in FIG2, the parallel connector 56 includes a positive parallel connector 561 and a negative parallel connector 562. The positive parallel connector 561 is used to connect the main photovoltaic positive terminal connector 5511 and the auxiliary photovoltaic positive terminal connector 5512 in parallel, and the negative parallel connector 562 is used to connect the main photovoltaic negative terminal connector 5521 and the auxiliary photovoltaic negative terminal connector 5522 in parallel. Optionally, the parallel connector 56 is a T-type adapter.

[0110] In some embodiments of this application, referring to Figures 1-3, 7-8, and 11-12, the solar photovoltaic panel assembly 10 further includes a junction box waterproof cover 54. The junction box waterproof cover 54 is adapted to be installed and fixed in the junction box 53, forming a waterproof space between the junction box waterproof cover 54 and the junction box 53. The connection points of the main photovoltaic panel 2 and its corresponding connector 55, and the connection points of the auxiliary photovoltaic panel 3 and its corresponding connector 55 are located within the waterproof space. Specifically, the connection points of the main photovoltaic positive electrode line 23 and the main photovoltaic positive electrode connector 5511, the main photovoltaic negative electrode line 24 and the main photovoltaic negative electrode connector 5521, the auxiliary photovoltaic positive electrode line 33 and the auxiliary photovoltaic positive electrode connector 5512, and the auxiliary photovoltaic negative electrode line 34 and the auxiliary photovoltaic negative electrode connector 5522 are located within the waterproof space. The junction box waterproof cover 54 can protect the waterproof space, thereby improving electrical safety.

[0111] In some embodiments of this application, the drive component 4 further includes a first limit switch and a second limit switch. The first limit switch limits the maximum extension position of the multi-stage telescopic rod 42 extending from the drive mechanism 41, and the second limit switch limits the maximum retraction position of the multi-stage telescopic rod 42 retracting into the drive mechanism 41. By limiting the extreme positions of the multi-stage telescopic rod 42 through the first and second limit switches, the drive motor 411 can be prevented from overtraveling and burning out, thereby making the extension and retraction actions of each stage of the telescopic rod 42 more reliable and less prone to damage. Specifically, the first and second limit switches limit the extreme position of the final stage telescopic rod 422. When the final stage telescopic rod 422 extends from the drive mechanism 41 to its maximum extension position, the final stage telescopic rod 422 triggers the first limit switch to generate a first signal to control the drive motor 411 to stop. When the final stage telescopic rod 422 retracts into the drive mechanism 41 to its maximum retraction position, the final stage telescopic rod 422 triggers the second limit switch to generate a second signal to control the drive motor 411 to stop.

[0112] In some embodiments of this application, the drive mechanism 41 includes a multi-stage lead screw, with each stage of the telescopic rod screwed to a corresponding lead screw. The multi-stage lead screw includes a final stage lead screw 413, with a rocker arm socket 415 at its end. The final stage telescopic rod 422 has an emergency reserved hole 423 at its end, which allows a rocker arm to extend into the rocker arm socket 415. Rotating the rocker arm is suitable for driving the multi-stage lead screw to rotate, thereby causing the multi-stage telescopic rod 42 to extend or retract relative to the drive mechanism 41. Traditional electric push rods cannot extend or retract after power loss or damage. The drive component 4 used in this application can extend or retract the telescopic rod 42 using a rocker arm in emergency situations. In other words, the manual rocker arm function is for the convenience of users in the event of a malfunction of the telescopic rod 42 or a lack of power, preventing the auxiliary photovoltaic panel 3 from failing to retract and affecting driving safety.

[0113] Specifically, in some embodiments, the drive mechanism 41 includes a drive motor 411 and a two-stage lead screw. The two-stage lead screw includes a first-stage lead screw 412 and a last-stage lead screw 413. The drive motor 411 is used to drive the first-stage lead screw 412 to rotate. Each stage of the telescopic rod 42 is provided with a nut that is screwed to the corresponding lead screw. When the drive motor 411 drives the first-stage lead screw 412 to rotate in the forward direction, the forward rotation of the first-stage lead screw 412 can be transmitted to the last-stage lead screw 413, and the nuts of each stage of the telescopic rod 42 drive the corresponding telescopic rod 42 to extend. When the drive motor 411 drives the first-stage lead screw 412 to rotate in the reverse direction, the reverse rotation of the first-stage lead screw 412 can be transmitted to the last-stage lead screw 413, and the nuts of each stage of the telescopic rod 42 drive the corresponding telescopic rod 42 to retract. Of course, the drive motor 411 can also use other transmission mechanisms to drive the extension or retraction of each telescopic rod 42, such as a gear and rack transmission mechanism. The output shaft of the drive motor 411 is equipped with a gear, and each telescopic rod 42 is equipped with a rack that meshes with the gear. When the drive motor 411 drives the gear to rotate in the forward direction, the gear drives the rack to drive the corresponding telescopic rod 42 to extend; when the drive motor 411 drives the gear to rotate in the reverse direction, the gear drives the rack to drive the corresponding telescopic rod 42 to retract.

[0114] In the embodiment shown in Figures 14-17, the driving component 4 includes a driving mechanism 41 and two-stage telescopic rods 42. The two-stage telescopic rods 42 include a first-stage telescopic rod 421 and a last-stage telescopic rod 422. One end of the first-stage telescopic rod 421 is located inside the driving mechanism 41. The first-stage telescopic rod 421 and the last-stage telescopic rod 422 are nested together. The outer end of the last-stage telescopic rod 422 is fixedly installed on the sub-photovoltaic panel 3. The drive mechanism 41 includes a drive motor 411 and two-stage lead screws, including a primary lead screw 412 and a secondary lead screw 413. A primary nut 4211, screwed to the primary lead screw 412, is mounted on the primary telescopic rod 421. A secondary nut 4221, screwed to the secondary lead screw 413, is mounted on the secondary telescopic rod 422. When the drive motor 411 drives the primary lead screw 412 to rotate forward, the primary nut 4211 extends the primary telescopic rod 421, and the secondary nut 4221 extends the secondary telescopic rod 422. When the drive motor 411 drives the primary lead screw 412 to rotate in the reverse direction, the primary nut 4211 retracts the primary telescopic rod 421, and the secondary nut 4221 retracts the secondary telescopic rod 422. The extension and retraction actions of the primary and secondary telescopic rods 421 and 422 can be synchronized or asynchronous. The principles governing the extension and retraction of the drive components of multi-stage telescopic rods are common mechanical principles in this field and will not be elaborated upon here.

[0115] In some embodiments of this application, the solar photovoltaic panel assembly 10 further includes an emergency limit lock 57. The emergency limit lock 57 is installed at the end of the main photovoltaic panel 2 away from the drive mechanism 41. Referring to Figures 3-4, the emergency limit lock 57 is installed at the F2 end of the main photovoltaic panel 2. The emergency limit lock 57 is used to at least limit the position where the secondary photovoltaic panel 3 slides outward. In special circumstances, such as when there is no power supply or the drive motor 411 is damaged, causing the telescopic rod 42 to be unable to extend or retract, a rocker arm can be inserted into the drive component 4 through the emergency reserved hole 423 to shake the internal mechanism and drive the telescopic rod 42 to extend or retract. The emergency limit lock 57 is then used to fix it and prevent the secondary photovoltaic panel 3 from sliding outward.

[0116] Referring to Figure 4, the emergency limit lock 57 includes a limit lock housing 571 with a limit lock hole 572. Fasteners pass through the limit lock hole 572 and are secured to the main photovoltaic frame 21, thereby achieving the installation and fixation of the emergency limit lock 57 on the main photovoltaic panel 2. The emergency limit lock 57 also has a latch 574, which is installed in the limit lock housing 571 and can be pushed to a blocking position that prevents the secondary photovoltaic panel 3 from sliding. The emergency limit lock 57 also has a reset button 573, which is installed in the limit lock housing 571. After pressing the reset button 573, the latch 574 returns to the non-blocking position, at which point the secondary photovoltaic panel 3 can slide relative to the main photovoltaic panel 2. Pressing the latch 574 of the emergency limit lock 57 prevents the secondary photovoltaic panel 3 from being thrown out during driving, thus preventing potential danger.

[0117] In some embodiments of this application, the solar photovoltaic panel assembly 10 further includes a waterproof plug 58, which is installed on the final stage telescopic rod 422 and seals the emergency reserved hole 423. When it is not necessary to manually drive the telescopic rod 42 to extend or retract, the waterproof plug 58 seals the emergency reserved hole 423, preventing external moisture and impurities from entering the drive component 4 through the emergency reserved hole 423. When it is necessary to manually drive the telescopic rod 42 to extend or retract, the waterproof plug 58 is removed from the emergency reserved hole 423, and the rocker arm can be inserted into the rocker arm socket 415 of the final stage lead screw 413 through the emergency reserved hole 423. At this time, turning the rocker arm can drive the final stage lead screw 413 to rotate, and the rotation of the first stage lead screw 412 can drive the final stage lead screw 413 to rotate, thereby driving the multi-stage telescopic rod 42 to extend or retract relative to the drive mechanism 41. In other words, in an emergency, simply remove the waterproof plug 58 from the end of the final-stage telescopic rod 422 (as shown in Figure 13), then insert the rocker arm into the emergency reserved hole 423 (as shown in Figure 10). The rocker arm will then connect to the rocker arm socket 415. Shaking the rocker arm will extend or retract the telescopic rod 42, causing the final-stage telescopic rod 422 to slide along the secondary photovoltaic panel 3. The waterproof plug 58 and the emergency reserved hole 423 can be an interference fit.

[0118] In some embodiments of this application, the solar photovoltaic panel assembly 10 also includes a controller for driving the telescopic rod 42 to extend or retract. Optionally, the controller is a controller equipped with a remote control or a controller controlled by an app. The controller is used to receive control commands to control the movement of the drive component 4, thus enabling remote control of the extension or retraction of the telescopic rod 42. For example, a user can issue control commands to the controller from inside the passenger compartment to control the extension or retraction of the telescopic rod 42 without having to go to the installation location of the solar photovoltaic panel assembly 10, which improves the user experience. The controller can be installed on the roof of the RV.

[0119] In some embodiments of this application, the controller can control and protect the telescopic pole 42 and record the state of the telescopic pole 42. The controller can be powered by a photovoltaic panel or by a lithium battery inside the RV or electrical device.

[0120] In some embodiments of this application, one controller can control four drive components 4 simultaneously. The controller has an obstruction detection function. When the auxiliary photovoltaic panel 3 is blocked during the sliding process, the controller will control the drive motor 411 to stop to prevent damage to the telescopic rod 42. Although one controller can connect to four drive components 4 at the same time, the obstruction detection function is separate, so there will be no situation where one drive component 4 is blocked and all four drive components 4 stop at the same time. The controller has a built-in remote control, which can be used to control the extension, retraction, and stopping of each telescopic rod 42. The controller can also be controlled through a mobile phone host computer, etc.

[0121] In some embodiments of this application, referring to Figures 1-3, 5, 7, 11, and 20-23, the solar photovoltaic panel assembly 10 further includes a fixed wing 6. The fixed wing 6 is fixedly mounted on both the first frame 11 and the second frame 12. One side surface of the fixed wing 6 has an adhesive groove 61. After applying adhesive to the adhesive groove 61, the fixed wing 6 can be fixed to the vehicle 100 or other electrical devices. The fixed wing 6 includes multiple adhesive-receiving arms 65. The adhesive groove 61 is defined by the gaps between the multiple adhesive-receiving arms 65. The surface of the adhesive-receiving arms 65 can be set as a wavy surface. During adhesive application, the wavy surface allows the adhesive to have more adhesion points to enhance adhesion, allowing the fixed wing 6 to bond more firmly to the vehicle roof or other substrate surfaces.

[0122] In some embodiments of this application, referring to Figures 1-3, 5, 7, 11, and 20-22, the end of the fixed wing 6 has a reserved screw position 62. The solar photovoltaic panel assembly 10 also includes a wing fixing bracket 7, which includes a first support plate 71 and a second support plate 72 connected together. The first support plate 71 is fixed to the reserved screw position 62, and the second support plate 72 has a fixing hole 721. Referring to Figures 20-23, the first support plate 71 has a support plate hole 711. The bracket bolt passes through the support plate hole 711 and is tightened to the reserved screw position 62, thereby realizing the connection and fixation between the wing fixing bracket 7 and the fixed wing 6. The fixing bolt passes through the fixing hole 721 and can be tightened to the base, thereby realizing the installation and fixation of the solar photovoltaic panel assembly 10 on the base. Optionally, the base can be a roof, the top of the vehicle body 20 of the vehicle 100, the ground, etc.

[0123] Optionally, multiple screw positions 62 are reserved, which helps to improve the connection between the wing fixing bracket 7 and the fixed wing 6.

[0124] Alternatively, multiple pre-drilled screw positions 62 are provided, and the number of support plate holes 711 is equal to the number of pre-drilled screw positions 62. The positions of the support plate holes 711 and the pre-drilled screw positions 62 correspond one-to-one. After the bolt passes through the support plate hole 711, it is tightened to the corresponding pre-drilled screw position 62. Thus, there are multiple connection and fixing points between the wing fixing bracket 7 and the fixed wing 6, which helps to improve the connection strength between the wing fixing bracket 7 and the fixed wing 6. In the embodiments shown in Figures 20-23, each wing fixing bracket 7 has two support plate holes 711. The wing fixing bracket 7 is connected and fixed to the pre-drilled screw positions 62 through the two support plate holes 711 and the bracket bolts.

[0125] In some embodiments of this application, referring to Figures 20-22, the side of the fixed wing 6 facing away from the adhesive groove 61 has a fastener slot 63. The solar photovoltaic panel assembly 10 also includes a wing fastening bolt. The wing fastening bolt passes through the first frame 11 or the second frame 12 and is fastened to the nut in the fastener slot 63, thereby realizing the installation and fixation of the fixed wing 6 on the first frame 11 or the second frame 12. After the fixed wing 6 is fixed in position on the base, the nut is placed in the fastener slot 63. Then, it is only necessary to place the first frame 11 and the second frame 12 into the corresponding main body slot 64 of the fixed wing 6, and then fasten it by the wing fastening bolt and the nut in the fastener slot 63, as shown in Figures 1-3, 5, 7, and 11.

[0126] In some embodiments of this application, as shown in Figures 20-22, the interior of the fixed wing 6 has a hollow structure, which can reduce the weight of the fixed wing 6 and lower the cost. The fixed wing 6 is a fixing frame for fixing the entire solar photovoltaic panel assembly 10. It can be fixed to the roof with structural adhesive or screws first, and then the entire support frame 1 is placed on it, which facilitates replacement, installation and disassembly.

[0127] In some embodiments of this application, referring to Figures 1, 3, 5, 7, and 24-25, both the first frame 11 and the second frame 12 include: a frame body 13, a photovoltaic panel support arm 14, and a wing mounting arm 15. The photovoltaic panel support arm 14 is connected to the frame body 13, and the main photovoltaic panel 2 is mounted on the corresponding photovoltaic panel support arm 14. The wing mounting arm 15 is connected to the frame body 13 and is located on the side of the frame body 13 away from the main photovoltaic panel 2. The fixed wing 6 has a main body slot 64, and the frame body 13 is embedded in the main body slot 64. The wing mounting arm 15 is provided with a mounting hole 151 that cooperates with the wing fastening bolt. After the wing fastening bolt passes through the mounting hole 151, it is fastened to the nut in the fastener slot 63, thus completing the connection and fixation of the fixed wing 6 to the corresponding frame.

[0128] In some embodiments of this application, referring to Figures 3, 5, 7, and 25-27, both the first frame 11 and the second frame 12 are provided with slide rails 8, and the sub-photovoltaic panel 3 is adapted to slide and cooperate with the slide rails 8 on both sides. The slide rails 8 on both sides guide the sliding movement of the sub-photovoltaic panel 3, thereby making the sliding movement of the sub-photovoltaic panel 3 more stable and smooth.

[0129] In some embodiments of this application, referring to Figures 3, 5, 7, and 25-27, the slide rail 8 is a multi-section slide rail, which includes at least a first slide rail 81 and a last slide rail 83. The first slide rail 81 is installed on the corresponding first frame 11 or second frame 12. The secondary photovoltaic panel 3 is installed on the last slide rail 83 via corner brackets 92.

The electrical energy in the energy storage battery can be used by electrical devices. The energy storage battery can directly provide DC power to the electrical devices, or it can provide AC power to the electrical devices via an inverter. Optionally, the energy storage battery can be a lithium battery, which is less expensive. The controller and energy storage battery can be placed inside the vehicle 100, with the wiring of the solar photovoltaic panel assembly 10 extending into the vehicle 100 to power the energy storage battery via the controller.

The length of the solar photovoltaic panel assembly 10 is H1, and the length of the top horizontal edge 201 is H2, where H1 < H2. The solar photovoltaic panel assembly 10 has a slender shape, which can maximize the use of the space on the top of the vehicle body 20.

[0142] According to the vehicle 100 of this application embodiment, its solar photovoltaic panel assembly 10 uses a main photovoltaic panel 2 to connect the first frame 11 and the second frame 12, eliminating the need for a separate frame to connect the first frame 11 and the second frame 12. This helps to reduce the overall weight of the supporting frame 1 and achieve a lightweight design of the overall structure of the solar photovoltaic panel assembly 10. By setting up the solar photovoltaic panel assembly 10, the auxiliary photovoltaic panel 3 can be slid outward relative to the main photovoltaic panel 2 to an unfolded position as needed, thereby expanding the power generation area of ​​the solar photovoltaic panel assembly 10 and increasing the power generation to meet the user's electricity demand.
