[0002] The new energy industry is a strategic and leading industry in the national economy, playing a vital role in driving economic growth, adjusting industrial structure, promoting industrial transformation and upgrading, and breaking through energy bottlenecks. Currently, combining new energy technologies with buildings is one implementation method with enormous energy-saving potential. Among these, the combination of low-energy houses, zero-carbon houses, and photovoltaic houses is constantly emerging. For example, patents CN214659127U (a multi-functional solar charging house) and CN209620683U (a solar photovoltaic power generation smart house) disclose this type of photovoltaic building integration implementation method. However, the above two implementation methods and similar photovoltaic houses currently circulating in the market are mostly single, independent structures with simple structures, lacking assembly and expansion functions, and their application methods and scenarios are obviously limited, requiring improvement.

Detailed Implementation

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 , Figure 2 As shown in the figure, a photovoltaic cabin unit is disclosed in a specific embodiment of the present invention, including a base 110, multiple support members 120 installed on the top of the base 110, a door 130 installed between two support members, a first photovoltaic panel 140 installed between any two adjacent support members, and a second photovoltaic panel 150 installed on the top of the multiple support members, forming a hexagonal prism structure with an internal space. The second photovoltaic panel and multiple first photovoltaic panels cover multiple wall surfaces, which can effectively expand the range and area of ​​sunlight exposure, thereby effectively improving the efficiency of power conversion to provide the required power supply. The hexagonal prism structure can strengthen the overall structural strength and facilitate the close connection of multiple photovoltaic cabin units, making it convenient to assemble and install the whole unit, realize the deformation of the outer contour structure and the expansion of the overall space, meet different application needs in terms of shape and space, and improve applicability and practicality. It should be noted that the photovoltaic panel is a mature photoelectric conversion component, and the matching battery and conversion control module are also mature mechanical structures that can be purchased and used on the market. The specific connection method and conversion usage method are not described in detail.

[0036] Furthermore, the base 110 has a hexagonal plate-like structure, and there are six support members 120. The support members 120 are respectively installed at the top hexagonal positions of the base 110 and are fixedly connected by bolts. The second photovoltaic panel 150 has a hexagonal plate-like structure, and the second photovoltaic panel corresponds to the base position. The second photovoltaic panel 150 is installed on the support member 120 by bolts. The two sides of the first photovoltaic panel 140 abut against the support member 120 and are fixedly connected by bolts. One side of the door is rotatably connected to one of the support members through a hinge, and the other side of the door is equipped with a door lock for locking the door. The whole adopts an assembled structure, which facilitates the processing and production of each structural component and is also convenient for assembly. In addition, the whole is a hexagonal prism structure with a flat outer wall surface, so as to ensure a tight connection between the two photovoltaic cabin units.

[0037] Furthermore, such as Figure 5 , Figure 6 As shown, the support 120 includes a column 121 and multiple clips 122 mounted on the column; a recess 111 is provided at the hexagonal position on the top surface of the base 110, and a mating foot 123 is fixedly provided on the bottom surface of the column 121. The shape of the mating foot 123 is adapted to the shape of the recess 111. The column is installed in the recess through the mating foot and fixed by bolts, which can increase the connection contact area between the column and the base and enhance the overall connection strength.

[0038] Card assembly 122 extends outward from the support 120 towards the center of base 110; the top surface of the uppermost card assembly is flush with the top surface of the pole, and the second photovoltaic panel 150 is bolted to the card assembly 122 at the top position; the bottom surface of the lowermost card assembly is flush with the top surface of the mating foot, and the bottom surface of the card assembly 122 at the bottom abuts against the top surface of base 110 and is fixedly connected by bolts; the support is also an assembled structure, especially the card assembly, which is a structural component connecting the support to the outside, and its structure is relatively complex. The separate column and card assembly structure can facilitate the separate processing and production of both, and the assembly method is simple and convenient for disassembly and replacement.

[0039] Furthermore, such as Figure 4 , Figure 15 As shown, the base 110 has a cavity 112 inside, and the cavity 112 has multiple channels 113 corresponding to the six side walls of the base. The ends of the channels extend through the side walls of the base. The center of the top surface of the base 110 has a first through hole 114, which communicates with the cavity. A filler is detachably installed at the first through hole. The shape of the filler is adapted to the shape of the first through hole, and the top surface of the filler is flush with the top surface of the base. A grid block 160 for ventilation is installed at the outer port of the channel 113 by bolts. The shape of the grid block is adapted to the shape of the outer port of the channel.

[0040] The system achieves external communication through a first perforation, clamping cavity, channel, and grid block, providing conditions for ventilation. A filler is installed at the first perforation; this filler can be removed, and ventilation equipment can be installed at the first perforation location to effectively enhance the overall ventilation effect. Furthermore, the filler has a cap-like structure, appropriately positioned at the first perforation to prevent the first perforation from being recessed and affecting the flatness of the base's top surface, thus preventing subsequent bumps or other problems. The bottom of the filler has multiple second notches, and the top of the filler has at least one fifth perforation, thereby achieving communication with the clamping cavity and channel. It should be noted that the fifth perforation can also be plugged with a rubber stopper, optional depending on the actual usage, to prevent multiple exhaust or intake points from affecting the gas circulation of the ventilation equipment.

[0041] Furthermore, such as Figures 5 to 7 As shown, the two intersecting walls of the column 121 away from the center of the base 110 are flush with the two walls at the corner of the base 110; the top, middle and bottom of the column 121 are provided with inwardly recessed slots 124; the card set 122 includes a V-shaped plate 1221, the V-shaped plate 1221 is adapted to the shape of the slot 124, the V-shaped plate is tightly fitted to the slot and fixed by bolts; the card set is secured to the slot by the V-shaped plate, which effectively prevents the card set from falling off, and the step surface of the slot can be used to provide stable support for the card set;

[0042] The outer corner of the V-shaped plate 1221 extends outward to form a thickened portion 1222. A groove 1223 is provided at the corner of the thickened portion 1222. First countersunk holes 1224 are provided on both the upper and lower walls of the groove 1223. The card kit is connected to the base or the second photovoltaic panel by bolts passing through the first countersunk holes. The card kit expands the connection area between the card kit and the base and the second photovoltaic panel, effectively strengthening the connection. First insertion holes 1225 are provided on both sides of the thickened portion 1222. The first insertion holes 1225 are connected to the groove 1223. The first insertion holes are rectangular holes, and the two first insertion holes are parallel to the two sides of the V-shaped plate. The thickened portion 1222 is provided with second through holes 1226 corresponding to the first insertion holes 1225, providing a place for the subsequent first mating parts to be inserted and connected, so as to realize the connection between the two card kits.

[0043] Furthermore, the position of the door lock corresponds to the position of the thickened part, and the lock tongue of the door lock corresponds to the second through hole position of the corresponding card kit. The card kit is used as a component that cooperates with the door lock to achieve effective locking.

[0044] Furthermore, the mounting frame of the first photovoltaic panel has multiple first notches corresponding to the card kit to prevent installation interference problems; the card kit can also play an alignment role. When the mounting frame abuts against the end face of the thickened part, the alignment can be completed, which facilitates the installation of the first photovoltaic panel.

[0045] The present invention also discloses a house, such as Figures 11 to 14 As shown, the system includes multiple photovoltaic cabin units 100; and a first connecting piece 200, a second connecting piece 300, and a bracket 400 for splicing the photovoltaic cabin units. The first connecting piece 200 is used for connecting two adjacent card sets 122; the second connecting piece 300 is used for connecting three interconnected bases 110 that converge at a center; the bracket 400 is mounted on the inner top of the three interconnected photovoltaic cabin units 100 that converge at a center, supporting multiple second photovoltaic panels 150. By using different connecting pieces to connect different structural components, a suitable assembly method can be selected according to different usage requirements and scenarios, thereby improving applicability and practicality.

[0046] Furthermore, the snap-fit ​​fittings of the two connecting support members are closely adjacent to each other, and the positions of the first insertion holes correspond. The first docking member 200 passes through the first insertion hole 1225 of the two snap-fit ​​fittings 122. The first docking member 200 is fixedly connected to the two snap-fit ​​fittings 122 by bolts. The recess 111 extends along both sides of the corner of the base 110, and the side of the recess 111 away from the center of the base 110 is open. When the three bases meet at the same center, the shape formed by the multiple connecting recesses 111 is adapted to the shape of the second docking member 300. The second docking member is snapped into the multiple recesses and fixed by bolts. This connection method requires disassembly and assembly of the support members in this part.

[0047] The bracket 400 has three support bars arranged in a circular array around the center. The ends of the support bars away from the center of the bracket are bent at 90°. The bent part 430 has a second insertion hole 440 that passes through both sides. The width of the support bar is adapted to the spacing between the thickened parts of the two connecting clips 122. When the bent part 430 is engaged between the two connecting clips 122, the position of the second insertion hole 440 corresponds to the position of the first insertion hole 1225. The first connecting piece 200 passes through the second insertion hole 440. The bracket is supported between multiple support members. The ends of the support bars are supported by the first connecting piece. The bracket is in a suspended state through multiple support points, which does not occupy the space below and can also support the second photovoltaic panel on the top.

[0048] More specifically, appropriate combinations are made according to different assembly requirements;

[0049] When there are only two photovoltaic house units or multiple photovoltaic house units are spliced ​​together on only one side, only the first connecting piece is needed to reinforce the connection of the splicing support parts, and no other connecting pieces are required to complete the assembly.

[0050] When three photovoltaic cabin units are connected at a central point, it means that three support members are connected, as well as multiple sets of two support members connected. If the user does not mind the space occupied by the three middle support members, only the first connecting piece can be used for connection and assembly. Alternatively, brackets can be added to further strengthen the structure of the connected multiple sets of support members and to reinforce the second photovoltaic panel on top. If the user is concerned about the space occupied by the three middle support members, the middle support members need to be removed. The second connecting piece can be used to connect and strengthen the confluence of the bases, and brackets can be added to strengthen the structural strength and support the second photovoltaic panel on top.

[0051] When more complex components are required for multiple photovoltaic cabin units, appropriate assembly and support methods should be selected based on the specific support conditions to ensure the stability of the overall structure.

[0052] Furthermore, such as Figure 8 As shown, the bracket 400 includes a U-shaped frame 450. A first support strip 410 is fixedly provided at the center of the side of the U-shaped frame 450 away from the opening. Second support strips 420 are fixedly connected to both sides of the opening of the U-shaped frame 450. The first support strip 410 and the two second support strips 420 are arranged in a circular array around the center of the U-shaped frame 450. The opening of the U-shaped frame is larger than the maximum distance between the two spliced ​​clip sets, which can facilitate the U-shaped frame to be directly clipped onto the spliced ​​multiple support members, making installation convenient.

[0053] A snap-fit ​​structure 500 is provided at the connection between the U-shaped frame 450 and the first frame strip 410. The snap-fit ​​structure 500 can be snapped between two adjacent snap-fit ​​kits 122. When installing the bracket, the bracket can be initially fixed by the snap-fit ​​structure so that the bracket is erected in the required position. Then, the first mating piece is installed at the connection between the end of the frame strip and the snap-fit ​​kit to effectively limit and facilitate the overall assembly operation. The U-shaped frame structure provides a position for snapping and alignment, which facilitates the erection and installation of the bracket and also facilitates the subsequent disassembly of the inner ring support of the U-shaped frame.

[0054] Furthermore, such as Figure 9 , Figure 10As shown, the snap-fit ​​structure 500 includes a spring 510, a snap-fit ​​block 520, a support 530, a pusher 540, a spring 550, and a guide bolt 560. A snap-fit ​​frame 460 is fixedly provided on the bottom surface of the connection between the U-shaped frame 450 and the first support bar 410. The side of the snap-fit ​​frame 460 near the center of the U-shaped frame protrudes from the side wall of the U-shaped frame 450, and the width of the snap-fit ​​frame 460 is adapted to the width of the first support bar 410. A fourth through hole 461 is provided on both sides of the protruding end of the snap-fit ​​frame 460, and the shape of the fourth through hole 461 is adapted to the shape of the first insertion hole 1225. The snap-fit ​​frame is open at one end away from the U-shaped frame. A support column 470 is fixedly provided on the first support bar 410 near the inner side of the open opening of the snap-fit ​​frame. The diameter of the support column 470 is adapted to the bent part of the spring 510. The support 530 is installed at the bottom of the snap-fit ​​frame 460, and the spring 510 is snapped into the first support bar 410 and the support 530. Between 0; the locking block 520 is fixedly disposed on the outer sides of both ends of the spring piece 510, the shape of the locking block 520 is adapted to the shape of the fourth through hole 461, and the locking block protrudes outward from the fourth through hole under the elastic force of the spring piece; the support member 530 is provided with a support block 531 near the opening of the locking block, the width of the support block is smaller than the width of the opening; the pushing member 540 includes a push plate 541, two opposing clamping plates 542 fixedly disposed on one side of the push plate, the distance between the two clamping plates 542 is adapted to the width of the support block 531, and the thickness of the clamping plates is adapted to the distance between the support block and the inner wall of the locking frame; the guide bolt 560 is installed on the wall surface of the support block 531 away from the locking block, the push plate is provided with a corresponding guide hole, and the push plate 541 is slidably disposed on the guide bolt 560; the spring 550 is sleeved on the guide bolt 560, located between the push plate and the support block, and provides a resetting thrust for the pushing member;

[0055] Two clamping plates are positioned on either side of the spring piece. When the pusher is pushed inward, the clamping plates compress the sides of the spring piece, causing the locking block to retract into the fourth through hole, thus unlocking the device. The buckle structure adopts an assembly-type structure, which facilitates the processing and production of each structural component and makes assembly easier. It uses a simple push-to-unlock method. When the pusher applies force inward, it compresses the spring piece, causing the locking block to retract into the fourth through hole. At this time, the protruding part of the locking frame can be inserted into the gap between the two mating locking pieces. After the force is released, the pusher resets under the action of the spring, thus releasing the compression of the spring piece. The locking block is pushed outward under the force of the spring piece and inserts into the first insertion hole, realizing the required locking action and initially setting up the bracket.

[0056] Furthermore, the end of the clamp is arc-shaped so that the clamp can be inserted between the spring and the inner wall of the frame, which facilitates pushing and squeezing the spring; and the inner side of the clamp is fixed with a protrusion, which can prevent the pushing part from falling off the frame and enhance the pushing and squeezing of the spring, ensuring that the card block can be smoothly retracted to the fourth through hole and achieve effective unlocking.

[0057] Furthermore, the inner corner shape of the U-shaped frame matches the shape of the two splicing card sets, facilitating alignment. When the U-shaped frame is snapped onto the outside of the card sets, the snap-fit ​​structure extends between the two splicing card sets, achieving initial snap-fit. The corresponding frame strip ends also snap into the area between the corresponding splicing card sets, achieving overall alignment.

[0058] Furthermore, such as Figure 4 , Figure 15 As shown, the end of the channel 113 furthest from the center of the base has a rectangular slot 115. The length of the slot is greater than the width of the channel, and the height of the slot is the same as the height of the channel. The grid block has a rectangular structure, and the shape of the grid block 160 matches the shape of the slot 115. The grid block is placed in the slot and fixed by bolts. Limiting blocks 116 are fixed on both sides of the channel 113. The distance between the two limiting blocks 116 is less than twice the width of the grid block 160, and the distance from the end face of the limiting block 116 to the side wall of the base 110 is half the length of the grid block 160. This structural design can achieve different effects by changing the placement of the grid blocks. When the grid block is placed in the slot, it acts as a normal ventilation grid. When the grid block is inserted and held against the limiting block, it can connect the two spliced ​​bases, acting as a connector and effectively strengthening the connection between the two bases.

[0059] Furthermore, the grid block has third through holes at both ends, and the top surface of the base has first threaded holes corresponding to the two ends of the bayonet. The first threaded holes extend to the bottom wall of the bayonet, and the position of the first threaded holes corresponds to the position of the third through holes. The top surface of the base has a second threaded hole on the side of the port of the limiting block near the bayonet. When the orientation of the grid block is adjusted, the end of the grid block is inserted into the clamp, and the position of the third through hole corresponds to the position of the second threaded hole. This ensures that the grid block can be effectively fixed, achieving the effect of placement and fixing in different orientations, and also achieving splicing and fixing between the two bases. With this method of use, after subsequent disassembly and assembly, the grid block can be readjusted and installed back into the bayonet, which can prevent loss.

[0060] Furthermore, the grid block has a rectangular block structure, with an air cavity inside and air holes on each side wall to facilitate airflow; multiple pads are fixed inside the air cavity to strengthen the overall structure of the grid block.

[0061] More specifically, the assembly process of a house composed of multiple photovoltaic cabin units includes the following steps:

[0062] S1. First, determine the specific shape of the structure, including the location of the door, the connecting walls between the photovoltaic cabin units, and the internal space distribution; then determine the door, the first photovoltaic panel, and the supporting components to be disassembled, as well as the installation location of the bracket; and design the installation sequence.

[0063] S2, disassemble the door and the first photovoltaic panel that need to be disassembled;

[0064] S3, remove the grid block at the bottom of the mating wall and reinstall it in the opposite direction so that the outside of the grid block protrudes outward;

[0065] S4. Move the photovoltaic cabin units to be assembled in sequence to align and install their bases.

[0066] S5, the pre-set support components that need to be assembled are assembled and connected through the first mating part; note that some areas need to be left empty for subsequent installation of brackets;

[0067] S6, install the bracket at the preset position;

[0068] S7, disassemble the support components that need to be removed;

[0069] S8, install the second docking piece at the empty sinkhole to complete the assembly of the outer contour;

[0070] In step S4, alignment can be achieved by connecting the sidewalls of the two protruding grid blocks. Then, the entire photovoltaic cabin unit is moved so that the grid blocks are fully inserted into the corresponding channels, and then fixed with bolts.

[0071] In step S6, the three support members at the center of the three photovoltaic cabin units are used as guides and initial supports, specifically including the following steps:

[0072] B1. Position the U-shaped bracket under the multiple clips on the top of the support; adjust the positions of the first and second brackets so that their ends correspond to the area between the outer clips.

[0073] B2, by unlocking the buckle structure, the card block is retracted; and the bracket is lifted from bottom to top, so that the U-shaped frame is fitted on the outside of the corresponding card set; and the protruding part of the buckle structure is also engaged in the part between the corresponding two card sets, and the ends of the first and second frame strips are also engaged in the part between the corresponding two card sets.

[0074] B3, release the force on the pusher, the spring returns to its original position, and the locking block extends and enters the adjacent first insertion hole, so that the bracket is locked in the preset position;

[0075] B4. At the positions corresponding to the ends of the first and second brackets, insert the first connecting piece into the first insertion hole of the corresponding card set, so that the first connecting piece passes through the corresponding second insertion hole, and fixes and supports the ends of the first and second brackets; thus completing the installation of the bracket.

[0076] In step S7, some support components need to be disassembled, especially the support components inside the U-shaped frame. The support components can be disassembled and removed one by one through the opening of the U-shaped frame.
