DETAILED DESCRIPTION

[0066] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0067] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0068] Combine the following Figure 1-Figure 28 The solar photovoltaic panel assembly 10 , the vehicle 100 including the solar photovoltaic panel assembly 10 , and the electrical device including the solar photovoltaic panel assembly 10 according to the embodiment of the present invention are described in detail.

[0069] The solar photovoltaic panel assembly 10 according to the present invention can be applied not only to a vehicle 100, such as a motorhome, but also to other electrical devices, such as a house roof, etc. For the convenience of description, the structure of the solar photovoltaic panel assembly 10 is described below by taking the application of the solar photovoltaic panel assembly 10 to a vehicle 100 as an example.

[0070] Reference Figure 1-Figure 3 , Figure 5 , Figure 7 , Fig.11 As shown, the solar photovoltaic panel assembly 10 according to the embodiment of the utility model includes: a supporting frame 1, a main photovoltaic panel 2 and a secondary photovoltaic panel 3.

[0071] The support frame 1 is a split frame, and the support frame 1 includes a first frame 11 and a second frame 12, the first frame 11 and the second frame 12 are arranged opposite to each other; the main photovoltaic panel 2 is located between the first frame 11 and the second frame 12, and the first frame 11 and the second frame 12 are connected through the main photovoltaic panel 2. The auxiliary photovoltaic panel 3 is located between the first frame 11 and the second frame 12, and the auxiliary photovoltaic panel 3 can slide along the first frame 11 and / or the second frame 12 to a storage position where the overlapping area with the main photovoltaic panel 2 in the thickness direction is the largest and to a deployment position where it slides outward relative to the main photovoltaic panel 2.

[0072] In other words, a photovoltaic panel installation space is formed between the first frame 11 and the second frame 12, and the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are both located in the photovoltaic panel installation space. Figure 2The F3 end shown in FIG. 1 is connected to the first frame 11, and the other end of the main photovoltaic panel 2 (as shown in FIG. Figure 2 The first frame 11 and the second frame 12 are connected to each other by the main photovoltaic panel 2, and the first frame 11 and the second frame 12 are connected only by the main photovoltaic panel 2, without relying on other frames. The traditional support frame adopts a structure that fully surrounds the photovoltaic panel on all sides, which will increase the cost and installation difficulty of the solar photovoltaic panel assembly. In order to reduce the cost and installation difficulty, the structure of the support frame 1 is optimized in this application, and 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 the solar photovoltaic panel assembly 10 needs to be installed on the surface of the substrate, it is only necessary to fix the first frame 11 and the second frame 12 on the surface of the substrate.

[0073] The secondary photovoltaic panel 3 can slide along the first frame 11 and / or the second frame 12 to the storage position and the deployment position. Figure 1 , Fig.11 The position shown is the storage position, and the secondary photovoltaic panel 3 is in Figure 2-Figure 3 , Figure 5 , Figure 7 The position shown is the expanded position, and Figure 2 , Figure 7 The position shown is the partially expanded position. Figure 3 , Figure 5 The position shown is the fully deployed position. Optionally, the secondary photovoltaic panel 3 can slide to the storage position and the deployed position only along the first frame 11, can slide to the storage position and the deployed position only along the second frame 12, or can slide to the storage position and the deployed position along both the first frame 11 and the second frame 12.

[0074] The first frame 11 and the second frame 12 are used as bearing members for bearing the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3, and play a role of fixing and supporting the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3. At the same time, the main photovoltaic panel 2 plays a role of connecting the first frame 11 and the second frame 12, so that the solar photovoltaic panel assembly 10 becomes a whole, which is convenient for the overall transportation, assembly and disassembly of the solar photovoltaic panel assembly 10. The solar photovoltaic panel assembly 10 of the utility model has a stable and reliable structure, a long service life, and a good use effect.

[0075] The main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are stacked in the thickness direction, that is, the large surface of the main photovoltaic panel 2 (i.e., the surface with a larger area) and the large surface of the auxiliary photovoltaic panel 3 (i.e., the surface with a larger area) are arranged relative to each other, so that the space in the thickness direction of the support frame 1 can be reasonably utilized, 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, the height dimension of the vehicle 100 will not be significantly increased, so that the solar photovoltaic panel assembly 10 has little effect on the passability of the vehicle 100. The thickness direction of the support frame 1, the main photovoltaic panel 2, and the auxiliary photovoltaic panel 3 is Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig.11 The F5-F6 direction shown in .

[0076] Optionally, the main photovoltaic panel 2 is a plate-shaped 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 arranged in a non-slip structure to reduce the number of sliding parts in the solar photovoltaic panel assembly 10.

[0077] Similarly, the secondary photovoltaic panel 3 is a plate-shaped structure, and the large surface of the secondary photovoltaic panel 3 may be perpendicular to the thickness direction of the supporting frame 1 .

[0078] When the secondary photovoltaic panel 3 is in the storage position, Figure 1 , Fig.11 As shown, the overlapping area of ​​the secondary photovoltaic panel 3 and the main photovoltaic panel 2 in the thickness direction of the support frame 1 is the largest, that is, the secondary photovoltaic panel 3 and the main photovoltaic panel 2 can overlap to the greatest 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 a portion relative to the main photovoltaic panel 2, for example Figure 2 , Figure 7 The auxiliary photovoltaic panel 3 can also slide out completely relative to the main photovoltaic panel 2, for example Figure 3 , Figure 5 Shown in fully extended position.

[0079] When the secondary photovoltaic panel 3 slides outward relative to the main photovoltaic panel 2, as the degree of expansion increases, the overlapping area of ​​the secondary photovoltaic panel 3 and the main photovoltaic panel 2 in the thickness direction of the support frame 1 gradually decreases. When the secondary photovoltaic panel 3 retracts inward relative to the main photovoltaic panel 2, as the degree of expansion decreases, the overlapping area of ​​the secondary photovoltaic panel 3 and the main photovoltaic panel 2 in the thickness direction of the support frame 1 gradually increases.

[0080] 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 unfolded 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 stored 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 unfolded position, the power generation area of ​​the solar photovoltaic panel assembly 10 can be expanded, and the power generation power of the solar photovoltaic panel assembly 10 can be expanded, which is conducive to increasing the power generation to meet the user's electricity demand.

[0081] According to the solar photovoltaic panel assembly 10 of the embodiment of the utility model, the main photovoltaic panel 2 is used to connect the first frame 11 and the second frame 12, and there is no need to set up a frame for connecting the first frame 11 and the second frame 12. This is beneficial to reduce the total weight of the supporting frame 1 and realize the 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 much.

[0082] In some embodiments of the utility model, the secondary photovoltaic panel 3 is located on the side of the main photovoltaic panel 2 facing the installed substrate. When the secondary photovoltaic panel 3 is in the storage position, the main photovoltaic panel 2 can shield the secondary photovoltaic panel 3 to the maximum extent; when the secondary photovoltaic panel 3 is in the non-fully deployed position, the main photovoltaic panel 2 can partially shield the secondary photovoltaic panel 3. The shielding effect of the main photovoltaic panel 2 can prevent the upper debris from falling into the sliding track of the secondary photovoltaic panel 3, thereby protecting the sliding movement of the secondary photovoltaic panel 3, making the sliding of the secondary photovoltaic panel 3 more stable and smooth.

[0083] Specifically, the auxiliary photovoltaic panel 3 is one, and the auxiliary photovoltaic panel 3 and the main photovoltaic panel 2 together form a two-layer photovoltaic panel structure, which will not significantly increase the thickness of the solar photovoltaic panel assembly 10. When the solar photovoltaic panel assembly 10 is installed on the body 20 of the vehicle 100, the height direction of the vehicle 100 will not be significantly increased, so that the solar photovoltaic panel assembly 10 has little effect 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, both of which are Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig.11 The F5-F6 direction shown in .

[0084] 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 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 body 20 of the vehicle 100. When the vehicle 100 is driving, the additional auxiliary photovoltaic panel 3 can be hidden under the uppermost main photovoltaic panel 2 to improve the driving safety of the vehicle 100. When the vehicle 100 stops driving, the hidden auxiliary photovoltaic panel 3 can be extended through the driving member 4, thereby achieving the purpose of expanding the power generation.

[0085] In addition, the solar photovoltaic panel assembly 10 is designed as a two-layer structure including a main photovoltaic panel 2 and a secondary photovoltaic panel 3. It can be made into a suitable size and weight to meet the demand for additional power generation, has better practicality, and is designed as a two-layer structure without increasing the height too much.

[0086] 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 assembly 10 is close to 400W.

[0087] Of course, without considering the above factors, in other embodiments of the present invention, the number of the auxiliary photovoltaic panels 3 may be multiple, such as two, three or more, so that the user can slide the auxiliary photovoltaic panel 3 to the unfolded position as needed to increase the power generation area of ​​the solar photovoltaic panel assembly 10.

[0088] In some embodiments of the present invention, the solar photovoltaic panel assembly 10 further includes a driving member 4, which is fixedly mounted on the main photovoltaic panel 2 and is used to drive the auxiliary photovoltaic panel 3 to slide. In some embodiments, the driving member 4 is an electric cylinder to push the auxiliary photovoltaic panel 3 to slide outward relative to the main photovoltaic panel 2, or to pull the auxiliary photovoltaic panel 3 to retract inward relative to the main photovoltaic panel 2. By providing the driving member 4, the movement of the auxiliary photovoltaic panel 3 can be electrified, which is conducive to improving the user experience.

[0089] In some embodiments of the present invention, referring to Figure 7-Figure 8 , Figure 10-Figure 17As shown, the driving member 4 is in the form of an electric telescopic rod, and the driving member 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 final-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 in the driving mechanism 41, the two adjacent telescopic rods 42 are nested, the final-stage telescopic rod 422 is fixedly connected to the auxiliary photovoltaic panel 3, and the driving mechanism 41 can drive the multi-stage telescopic rod 42 to extend or retract relative to the driving mechanism 41. The driving mechanism 41 includes a driving motor 411 and a telescopic rod storage bin 414, the driving motor 411 is installed in the internal space of the telescopic rod storage bin 414, when the multi-stage telescopic rod 42 extends outward relative to the telescopic rod storage bin 414, the multi-stage telescopic rod 42 pushes the auxiliary photovoltaic panel 3 to slide outward; when the multi-stage telescopic rod 42 retracts inward relative to the telescopic rod storage bin 414, the multi-stage telescopic rod 42 pulls the auxiliary photovoltaic panel 3 to retract inward. The electric telescopic rod 42 automates the sliding movement of the secondary photovoltaic panel 3, saving the user's physical strength. Optionally, when the drive motor 411 rotates forward, the multi-stage telescopic rod 42 can be driven to extend outward; when the drive motor 411 rotates reversely, the multi-stage telescopic rod 42 can be driven to retract inward.

[0090] In some embodiments of the utility model, the multi-stage telescopic rod 42 is a rod-shaped structure, and the telescopic direction of each stage of the telescopic rod 42 is parallel to the sliding direction of the auxiliary photovoltaic panel 3. In the related art, the solar photovoltaic panel assembly includes a main photovoltaic panel and an auxiliary photovoltaic panel, and the auxiliary photovoltaic panel is slid by a traditional electric push rod. The traditional electric push rod includes a first-stage push rod, and the length extension direction of the push rod is parallel to the sliding direction of the auxiliary photovoltaic panel. If a one-meter stroke is required, the overall length of the push rod needs to be 20 cm longer than the stroke, which results in the frame requiring a larger volume to accommodate the electric push rod, directly increasing the frame and affecting the volume and weight of the finished product, which brings great difficulties to the installation of the product. If a stroke of 700mm is required, the overall length of the push rod will reach 855mm, that is, the stroke range it can reach is smaller than its overall length. In the present application, by setting the telescopic rod 42 to multiple stages, the overall length of the driving member 4 can be shortened. For example, the overall length of the driving member 4 is 690mm, but the stroke can reach 730mm. That is, the driving member 4 of the present application can achieve a larger stroke range than its overall length due to the multi-stage telescopic rod 42. At the same time, the extension direction of each telescopic rod 42 is parallel to the sliding direction of the secondary photovoltaic panel 3, so that the driving force of the telescopic rod 42 on the secondary photovoltaic panel 3 is consistent with the sliding direction of the secondary photovoltaic panel 3, and the secondary photovoltaic panel 3 is not easy to deflect or get stuck, which is conducive to ensuring the smoothness of the sliding of the secondary photovoltaic panel 3.

[0091] In addition, the thickness of the conventional electric linear actuator is 40 mm, while the thickness of the driving member 4 used in the present application is only 25 mm, which is significantly thinner, and the driving member 4 used in the present application is lighter than the conventional electric linear actuator. The noise of the conventional electric linear actuator in operation is compared with the noise of the driving member 4 used in the present application in operation, and the noise of the driving member 4 used in the present application in operation is smaller.

[0092] In some embodiments of the present invention, the driving member 4 may be a DC electric telescopic rod, which has the characteristics of long extension, slow rotation speed, large torque, and can realize forward and reverse rotation through current commutation.

[0093] In some embodiments of the present invention, referring to Figure 7-Figure 8 , Figure 10-13 As shown, the driving member 4 is located on the side of the secondary photovoltaic panel 3 away from the main photovoltaic panel 2, so that the main photovoltaic panel 2 and the secondary photovoltaic panel 3 can block the driving member 4 to the maximum extent, and can prevent debris above the main photovoltaic panel 2 from falling on the driving member 4, so as to protect the telescopic action of the telescopic rod 42, so that the telescopic action of the telescopic rod 42 is more stable and smooth. The solar photovoltaic panel assembly 10 also includes a first fixed bracket 51 and a second fixed bracket 52, and the driving mechanism 41 is fixedly mounted on the main photovoltaic panel 2 through the first fixed bracket 51, and the final telescopic rod 422 is fixedly mounted on the secondary photovoltaic panel 3 through the second fixed bracket 52.

[0094] Reference Figure 7-Figure 9 , Figure 11-Figure 12 As shown, 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 the bracket arm 512 extends in the sliding direction of the secondary photovoltaic panel 3. A fixing nut 43 is provided on the driving mechanism 41, and a first bracket hole 513 corresponding to the position of the threaded hole of the fixing nut 43 is opened on the bracket arm 512. The bolt passes through the first bracket hole 513 and is fastened in the threaded hole of the fixing nut 43, thereby realizing the connection and fixation of the first fixed bracket 51 and the driving mechanism 41.

[0095] Optionally, the fixing nut 43 can be placed in a groove on the outer surface of the driving mechanism 41. The number of the fixing nuts 43 can be multiple. The groove on the outer surface of the driving mechanism 41 extends toward the sliding direction of the auxiliary photovoltaic panel 3. The multiple fixing nuts 43 are dispersedly arranged toward the sliding direction of the auxiliary photovoltaic panel 3. The first bracket hole 513 corresponds to the fixing nut 43 one by one, which is beneficial to improve the connection firmness between the first fixed bracket 51 and the driving mechanism 41.

[0096] Reference Figure 7 , Figure 10-11 , Fig.13As shown, the second fixing bracket 52 can be fastened to the secondary photovoltaic panel 3 by bolts, and a second bracket hole 521 is provided on the second fixing bracket 52. The bolt passes through the second bracket hole 521 and is fastened to the threaded hole of the final telescopic rod 422, thereby realizing the connection and fixation between the final telescopic rod 422 and the second fixing bracket 52. Optionally, the number of the second bracket holes 521 can be multiple, which is conducive to improving the connection firmness between the final telescopic rod 422 and the second fixing bracket 52.

[0097] In some embodiments of the present invention, the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 both include a photovoltaic frame and a photovoltaic laminate structure. The photovoltaic frame is arranged around the outer periphery of the photovoltaic laminate structure. The photovoltaic laminate structure is a laminate structure of tempered glass, EVA (Ethylene-Vinyl Acetate, ethylene-vinyl acetate copolymer) film, battery cells and backplane. The driving mechanism 41 is fixedly installed on the photovoltaic frame of the main photovoltaic panel 2 through the first fixed bracket 51, and the final telescopic rod 422 is fixedly installed on the photovoltaic frame of the auxiliary photovoltaic panel 3 through the second fixed bracket 52. Specifically, refer to Figure 8 and Fig. 9 As shown, 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. Fig.13 As shown, 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 fixing bracket 52 is fixedly installed on the secondary photovoltaic frame 31 .

[0098] Optionally, the photovoltaic frame is a frame structure that is circumferentially closed and penetrates along the thickness direction, and the photovoltaic laminated structure is installed in the circumferentially enclosed space of the photovoltaic frame. Specifically, the main photovoltaic laminated structure 22 is installed in the circumferentially enclosed space of the main photovoltaic frame 21, and the secondary photovoltaic laminated structure 32 is installed in the circumferentially enclosed space of the secondary photovoltaic frame 31.

[0099] In some embodiments of the present invention, 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 have the same size and model. When the auxiliary photovoltaic panel 3 is in the fully unfolded 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 storage 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 unfolded position, the power generation power of the solar photovoltaic panel assembly 10 can be expanded, for example, the power generation power of the solar photovoltaic panel assembly 10 can be increased by 1-2 times.

[0100] In some embodiments of the utility model, the profile thickness of the photovoltaic frame is 1.5mm~4mm, and threaded holes are provided on the photovoltaic frame. 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 ​​before 1.5mm~4mm, which are not listed here one by one. The profile thickness of the photovoltaic frame is in the range of 1.5mm~4mm, and threaded holes can be directly processed on the photovoltaic frame without the need to insert additional nuts, thereby making the installation between the photovoltaic frame and the support frame 1 more convenient. Refer to Figure 18-19 As shown, the main photovoltaic frame 21 includes a horizontal support arm 212 and a vertical support arm 213. Main threaded holes 211 are provided on the horizontal support arm 212 and the vertical support arm 213. The photovoltaic fastening bolts pass through the first frame 11 and are fastened to the corresponding main threaded holes 211, thereby completing the connection and fixation between the main photovoltaic frame 21 and the first frame 11.

[0101] Optionally, the photovoltaic frame may be an aluminum profile molded part, a copper profile molded part, or the like.

[0102] Optionally, the height of the photovoltaic frame is 16mm to 25mm, that is, the dimension of the photovoltaic frame in the thickness direction of the solar photovoltaic panel assembly 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 ​​between 16mm and 25mm, which are not listed here one by one. Compared with the thickness of more than 35mm of traditional photovoltaic panels, the height of the photovoltaic frame of the present application is significantly reduced, which is conducive to thinning the overall thickness of the photovoltaic panel, thereby facilitating the lightweight design of the solar photovoltaic panel assembly 10.

[0103] According to the embodiment of the utility model, the driving member 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 the sliding process and causing deviation and damage to the telescopic rod 42 or the auxiliary photovoltaic panel 3.

[0104] In some embodiments of the present invention, the first frame 11, the second frame 12 and the photovoltaic frame are all aluminum alloy frames. In this way, the first frame 11, the second frame 12 and the photovoltaic frame have good strength and light weight, which can realize the lightweight design of the solar photovoltaic panel assembly 10, and the use of aluminum alloy materials can also prevent rust and other problems during long-term use.

[0105] The aluminum alloy frame can be easily disassembled and assembled, with small packaging volume, low weight and low transportation cost. The main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are both aluminum alloy frame glass structures, with strong load-bearing capacity, firm structure, hard texture and longer service life. Since the conventional 195W photovoltaic frame is thicker and the height will reach 35mm, which will increase the height of the entire product, the solar photovoltaic panel assembly 10 of this application has specially redesigned the photovoltaic frame, and the photovoltaic frame is designed to 23mm while ensuring that the overall photovoltaic panel strength remains unchanged.

[0106] In some embodiments of the present invention, the solar photovoltaic panel assembly 10 further includes a junction box 53, which is fixed to the first fixing bracket 51. The junction box 53 is provided with a plug connector 55, and the main photovoltaic panel 2 and the auxiliary photovoltaic panel 3 are suitable for connecting with the corresponding plug connector 55.

Specifically, the junction box 53 is fixed on the bracket body 511 of the first fixing bracket 51 , and the junction box 53 and the first fixing bracket 51 are fixed as a whole and fixed on the main photovoltaic frame 21 .

[0107] A junction box 53 and a plug connector 55 are provided to collect the wiring. On the one hand, it can facilitate the user's wiring and concentrate the wiring positions at the junction box 53, which is beneficial to improving the wiring efficiency. On the other hand, it can prevent the user from walking the wiring by themselves, thus avoiding the problem of wiring harness entanglement and product failure caused by self-walking. The junction box 53 can bring together the wiring harnesses of multiple photovoltaic panels, which greatly facilitates the electrical connection between multiple photovoltaic panels. Optionally, the plug connector 55 is a conventional MC4 head, and the main photovoltaic positive line 23, the main photovoltaic negative line 24, the auxiliary photovoltaic positive line 33 and the auxiliary photovoltaic negative line 34 are MC4 lines. It is only necessary to buckle the MC4 line of the photovoltaic panel into the designed junction box 53 and lock it with the MC4 head (such as Figure 6 shown).

[0108] In some embodiments of the present invention, the solar photovoltaic panel assembly 10 further includes a parallel plug 56, which is used to realize parallel output of multiple photovoltaic panels, thereby increasing the charging current to meet different needs of users. Figure 2 As shown, the paralleling plug 56 includes a positive paralleling plug 561 and a negative paralleling plug 562. The positive paralleling plug 561 is used to connect the main photovoltaic positive plug 5511 and the auxiliary photovoltaic positive plug 5512 in parallel, and the negative paralleling plug 562 is used to connect the main photovoltaic negative plug 5521 and the auxiliary photovoltaic negative plug 5522 in parallel. Optionally, the paralleling plug 56 is a T-type conversion head.

[0109] In some embodiments of the present invention, referring to Figure 1-Figure 3 , Figure 7-Figure 8 , Figure 11-Figure 12 As shown, the solar photovoltaic panel assembly 10 also includes a junction box waterproof cover 54, which is suitable for being installed and fixed on the junction box 53. A waterproof space is formed between the junction box waterproof cover 54 and the junction box 53, and the connection between the main photovoltaic panel 2 and the corresponding plug connector 55, and the connection between the auxiliary photovoltaic panel 3 and the corresponding plug connector 55 are located in the waterproof space. Specifically, the connection between the main photovoltaic positive line 23 and the main photovoltaic positive plug connector 5511, the connection between the main photovoltaic negative line 24 and the main photovoltaic negative plug connector 5521, the connection between the auxiliary photovoltaic positive line 33 and the auxiliary photovoltaic positive plug connector 5512, and the connection between the auxiliary photovoltaic negative line 34 and the auxiliary photovoltaic negative plug connector 5522 are located in the waterproof space. The junction box waterproof cover 54 can protect the waterproof space, thereby improving electrical safety.

[0110] In some embodiments of the present utility model, the driving member 4 further includes a first limit switch and a second limit switch, wherein the first limit switch is used to limit the maximum extension position of the multi-stage telescopic rod 42 extending from the driving mechanism 41, and the second limit switch is used to limit the maximum retraction position of the multi-stage telescopic rod 42 retracting into the driving mechanism 41. By limiting the maximum position of the multi-stage telescopic rod 42 by the first limit switch and the second limit switch, the driving motor 411 can be prevented from being burned due to over-travel, thereby making the extension and retraction actions of the telescopic rods 42 at each level more reliable and the telescopic rods 42 less likely to be damaged. Specifically, the first limit switch and the second limit switch limit the extreme position of the final telescopic rod 422. When the final telescopic rod 422 is extended from the driving mechanism 41 to the extreme extension position, the final telescopic rod 422 triggers the first limit switch to generate a first signal to control the driving motor 411 to stop; when the final telescopic rod 422 is retracted into the driving mechanism 41 to the extreme retraction position, the final telescopic rod 422 triggers the second limit switch to generate a second signal to control the driving motor 411 to stop.

The traditional electric push rod cannot be extended or retracted after losing power or being damaged. The driving member 4 used in this application can use the rocker to extend and retract the telescopic rod 42 in an emergency. In other words, the manual rocker function is to facilitate the user to use the telescopic rod 42 when it fails or has no power during use, so as to prevent the auxiliary photovoltaic panel 3 from being unable to be retracted and affecting driving safety.

[0112] Specifically, in some embodiments, the driving mechanism 41 includes a driving motor 411 and a two-stage lead screw, the two-stage lead screw includes a first-stage lead screw 412 and a final-stage lead screw 413, the driving motor 411 is used to drive the first-stage lead screw 412 to rotate, and each stage of the telescopic rod 42 is provided with a nut threadedly connected to the corresponding lead screw. When the driving motor 411 drives the first-stage lead screw 412 to rotate forward, the forward rotation of the first-stage lead screw 412 can be transmitted to the final-stage lead screw 413, and the nuts of the telescopic rods 42 at each stage drive the corresponding telescopic rods 42 to extend; when the driving motor 411 drives the first-stage lead screw 412 to rotate reversely, the reverse rotation of the first-stage lead screw 412 can be transmitted to the final-stage lead screw 413, and the nuts of the telescopic rods 42 at each stage drive the corresponding telescopic rods 42 to retract. Of course, the driving motor 411 can also use other transmission mechanisms to drive the telescopic rods 42 at each level to extend or retract, such as a gear rack transmission mechanism. The output shaft of the driving motor 411 is provided with a gear, and the telescopic rods 42 at each level are provided with a rack that meshes with the gear. When the driving motor 411 drives the gear to rotate forward, the gear drives the rack to drive the corresponding telescopic rod 42 to extend; when the driving motor 411 drives the gear to rotate reversely, the gear drives the rack to drive the corresponding telescopic rod 42 to retract.

[0113] exist Figure 14-17In the illustrated embodiment, the driving member 4 includes a driving mechanism 41 and a two-stage telescopic rod 42, the two-stage telescopic rod 42 includes a first-stage telescopic rod 421 and a final-stage telescopic rod 422, one end of the first-stage telescopic rod 421 is located in the driving mechanism 41, the first-stage telescopic rod 421 and the final-stage telescopic rod 422 are nested, and the outer end of the final-stage telescopic rod 422 is fixedly mounted on the secondary photovoltaic panel 3. The driving mechanism 41 includes a driving motor 411 and a two-stage screw, the two-stage screw includes a first-stage screw 412 and a final-stage screw 413, a first-stage nut 4211 is provided on the first-stage telescopic rod 421 and is screwed to the first-stage screw 412, and a final-stage nut 4221 is provided on the final-stage telescopic rod 422 and is screwed to the final-stage screw 413.

The telescopic actions of the first-stage telescopic rod 421 and the final-stage telescopic rod 422 can be synchronized or asynchronous. The extension and retraction action principle of the driving member including the multi-stage telescopic rod is a common mechanical principle in the art and will not be described in detail here.

[0114] In some embodiments of the present invention, the solar photovoltaic panel assembly 10 further includes an emergency limit lock 57, which is installed at one end of the main photovoltaic panel 2 away from the driving mechanism 41. Figure 3-Figure 4 As shown, the emergency limit lock 57 is installed at the F2 end of the main photovoltaic panel 2, and the emergency limit lock 57 is at least used to limit the position of the auxiliary photovoltaic panel 3 sliding outward. In special cases, such as when the telescopic rod 42 cannot be extended due to no power supply or damage to the drive motor 411, the rocker can be inserted into the driving member 4 through the emergency reserved hole 423 to shake the internal mechanism to drive the telescopic rod 42 to extend and retract, and the emergency limit lock 57 is used to fix it to prevent the auxiliary photovoltaic panel 3 from sliding outward.

[0115] Reference Figure 4 As shown, the emergency limit lock 57 includes a limit lock housing 571, and the limit lock housing 571 has a limit lock hole 572. The fastener passes through the limit lock hole 572 and is fastened to the main photovoltaic frame 21, thereby realizing the installation and fixation of the emergency limit lock 57 on the main photovoltaic panel 2. The emergency limit lock 57 also has a lock tongue 574, which is installed in the limit lock housing 571. The lock tongue 574 can be pushed to a blocking position to block the sliding of the auxiliary photovoltaic panel 3. 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 lock tongue 574 is reset to a non-blocking position, and at this time, the auxiliary photovoltaic panel 3 can slide relative to the main photovoltaic panel 2.

[0116] In some embodiments of the utility model, the solar photovoltaic panel assembly 10 also includes a waterproof plug 58, which is installed on the final telescopic rod 422, and the waterproof plug 58 blocks the emergency reserved hole 423. When there is no need to manually drive the telescopic rod 42 to extend or retract, the waterproof plug 58 blocks the emergency reserved hole 423 to prevent external water vapor and impurities from entering the interior of the driving member 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 can be extended into the rocker socket 415 of the final screw 413 through the emergency reserved hole 423. At this time, rotating the rocker can drive the final screw 413 to rotate, and rotating the first screw 412 can drive the final screw 413 to rotate, thereby driving the multi-stage telescopic rod 42 to extend or retract relative to the driving mechanism 41. In other words, in an emergency, as long as the waterproof plug 58 (such as Fig.13 ), and then insert the rocker into the emergency reserved hole 423 (such as Fig.10 ) After that, the rocker will be connected to the rocker socket 415, and then the rocker is shaken to extend and retract the telescopic rod 42 so that the final telescopic rod 422 drives the secondary photovoltaic panel 3 to slide. The waterproof plug 58 and the emergency reserved hole 423 can be interference fit.

[0117] In some embodiments of the utility model, the solar photovoltaic panel assembly 10 further includes a controller, which is used to drive the telescopic rod 42 to extend or retract. Optionally, the controller is a controller equipped with a remote controller or a controller controlled by an APP, and the controller is used to receive control instructions to control the action of the driving member 4, so that the telescopic rod 42 can be remotely controlled to extend or retract. For example, the user can send a control instruction to the controller in the passenger compartment to control the telescopic rod 42 to extend or retract without having to go to the installation location of the solar photovoltaic panel assembly 10, which is conducive to improving the user experience. The controller can be installed on the roof of the RV.

[0118] In some embodiments of the present invention, the controller can control and protect the telescopic rod 42 and record the status of the telescopic rod 42. The power supply of the controller can be obtained through photovoltaic panels or powered by lithium batteries inside the RV or electrical devices.

[0119] In some embodiments of the utility model, one controller can control four driving members 4 at the same time. The controller has an obstruction detection function. When the secondary photovoltaic panel 3 is blocked during the sliding out process, the controller will control the driving motor 411 to stop to prevent the telescopic rod 42 from being damaged. Although one controller can connect to four driving members 4 at the same time, the obstruction function is separate. There will be no situation where one driving member 4 encounters an obstruction and causes the four driving members 4 to stop at the same time. The controller has its own remote control, and can control the extension and stop of each telescopic rod 42 by remote control. The controller can also be controlled by a mobile phone host computer, etc.

The fixed wing 6 includes a plurality of glue arms 65, and the glue groove 61 is defined by the gaps between the plurality of glue arms 65. The surface of the glue arms 65 can be set as a wavy surface. When applying glue, the wavy surface allows the glue to have more attachment positions to enhance the viscosity, so that the fixed wing 6 can be more firmly adhered to the roof or other substrate surface.

[0121] In some embodiments of the present invention, referring to Figure 1-Figure 3 , Figure 5 , Figure 7 , Fig.11 , Figure 20-22 As shown, the end of the fixed wing 6 has a reserved screw position 62, and 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 to each other.

Figure 20-23 As shown, a support plate hole 711 is provided on the first support plate 71, and the support bolt passes through the support plate hole 711 and is fastened 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 fastened 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 body 20 of the vehicle 100, the ground, etc.

[0122] Optionally, a plurality of screw positions 62 are reserved, which helps to enhance the connection firmness between the wing fixing bracket 7 and the fixed wing 6 .

[0123] Alternatively, there are multiple reserved screw positions 62, the number of support plate holes 711 is equal to the number of reserved screw positions 62, and the positions of the support plate holes 711 and the reserved screw positions 62 correspond one to one, and the bolts are fastened to the corresponding reserved screw positions 62 after passing through the support plate holes 711.
