[0002] A home photovoltaic energy storage battery pack is a photovoltaic energy storage system designed specifically for homes. It aims to generate and store electrical energy using solar power for home use when needed. This system combines photovoltaic power generation technology and energy storage technology to provide a sustainable energy solution that helps reduce home dependence on traditional grid electricity, lower electricity bills, and promote the use of renewable energy.

[0003] The housing of a residential photovoltaic (PV) energy storage battery pack is used to protect the energy storage battery, electrical components, and related management systems. However, the size of the housing is fixed, while the space for residential installation is not. This makes it difficult to adapt to the installation space, causing inconvenience during installation. Utility Model Content

[0004] The purpose of this utility model is to address the problem that the housing of a household photovoltaic energy storage battery pack, which is used to protect the energy storage battery, electrical components, and related management systems, cannot be adapted to the installation space during installation due to the fixed size of the housing and the variable space in a household, causing inconvenience during installation. Therefore, this utility model provides a housing for a household photovoltaic energy storage battery pack.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a housing for a household photovoltaic energy storage battery pack, comprising a housing body, the housing body comprising a first housing and a second housing, the second housing having a heat dissipation vent at one end for heat dissipation of the internal photovoltaic energy storage battery, the first housing and the second housing having an unfolding assembly for deformation and unfolding, the unfolding assembly comprising a U-shaped unfolding plate fixed to one end of the second housing and a U-shaped through groove opened at one end of the first housing and slidably adapted to the U-shaped unfolding plate, an adjusting plate for deformation adjustment and fixing fixedly installed inside the U-shaped through groove, a rotating shaft fixedly installed at one end of the U-shaped unfolding plate, and a first mounting block rotatably connected to the outer circumference of the rotating shaft, a second mounting block fixedly installed at one end of the first mounting block, and locking shafts symmetrically fixedly installed at both ends of the second mounting block, the adjusting plate having evenly spaced locking grooves for engaging with the locking shafts.

[0006] As a further embodiment of this utility model: one end of the U-shaped unfolding plate is fixedly mounted with an installation shaft, and one end of the installation shaft is fixedly mounted with an L-shaped elastic rod, and the top of the first mounting block is provided with a slot that matches the L-shaped elastic rod.

[0007] As a further embodiment of this utility model: one end of the adjusting plate is provided with a first straight groove for the L-shaped elastic rod to slide into the inner side of the slot, and one end of the adjusting plate and on the side opposite to the first straight groove is provided with a second straight groove for the L-shaped elastic rod to separate from the slot.

[0008] As a further improvement of this utility model, the retaining edge of one end of the card slot near the first straight groove is arc-shaped.

[0009] As a further improvement of this utility model: a sealing component for increasing sealing is provided on the inner side of the heat dissipation port. The sealing component includes a sealing membrane embedded in the heat dissipation port. An interlocking block that is fixedly installed at the bottom end of the sealing membrane and interlocking with the heat dissipation port is fixedly installed. An interlocking groove that is interlocking with the interlocking block is opened on the inner side of the heat dissipation port.

[0010] As a further embodiment of this utility model, the sealing assembly further includes a U-shaped sealing strip fixedly installed at one end of the first housing, and a U-shaped sealing groove adapted to the U-shaped sealing strip is provided at one end of the second housing.

[0011] As a further embodiment of this utility model: a mounting beam is fixedly installed on the inner side of the first housing and fixedly installed on the top cover, and the mounting beam is symmetrically fixedly installed at both ends of the inner side of the first housing; similarly, a mounting beam is symmetrically fixedly installed inside the second housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves pulling the second housing. When the second housing is pulled, it causes the first mounting block, which is rotatably connected to the outer circumference of the rotating shaft at one end of the U-shaped unfolding plate, to move. When the first mounting block is pulled, it causes the locking shafts at both ends of the second mounting block, which is fixed at one end, to move. Since the edge of one end of the locking groove is arc-shaped, the locking shaft is adjusted within multiple sets of locking grooves through the first mounting block and the rotating shaft when it is pulled. When the adjustment is to the required size, the pulling of the second housing is stopped. At this time, the adjustment of the size between the second housing and the first housing is completed. The unfolding component can adjust the size between the first housing and the second housing according to the installation space, which is convenient for installing the housing body in different installation spaces.

[0014] The sealing membrane not only increases the airtightness of the casing but also prevents external dust and larger particles from entering the casing and damaging the internal battery. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 5 In this embodiment of the utility model, a household photovoltaic energy storage battery pack housing includes a housing body 1, which includes a first housing 11 and a second housing 12. One end of the second housing 12 is provided with a heat dissipation port 14 for heat dissipation of the internal photovoltaic energy storage battery. The inner sides of the first housing 11 and the second housing 12 are provided with a deformable unfolding component 2. The unfolding component 2 includes a U-shaped unfolding plate 21 fixed to one end of the second housing 12 and a U-shaped through groove 22 opened at one end of the first housing 11 and slidably adapted to the U-shaped unfolding plate 21. An adjustment plate 23 for deformation adjustment and fixing is fixedly installed inside the U-shaped through groove 22. A rotating shaft 24 is fixedly installed at one end of the U-shaped unfolding plate 21, and a first mounting block 25 is rotatably connected to the outer periphery of the rotating shaft 24. A second mounting block 29 is fixedly installed at one end of the first mounting block 25, and a locking shaft 210 is symmetrically fixedly installed at both ends of the second mounting block 29. The inner side of the adjustment plate 23 is evenly provided with a locking groove 211 that engages with the locking shaft 210.

[0024] By implementing this method, the unfolding component 2 can adjust the size between the first housing 11 and the second housing 12 according to the installation space, which facilitates the installation of the housing body 1 in different installation spaces.

[0025] Reference Figures 1 to 5 The U-shaped unfolding plate 21 has an installation shaft 26 fixedly installed at one end, and an L-shaped elastic rod 27 is fixedly installed at the other end of the installation shaft 26. The top of the first installation block 25 has a slot 28 that matches the L-shaped elastic rod 27.

[0026] Through the implementation of this method: the L-shaped elastic rod 27 is made of spring steel, which is an iron-based alloy material with high elastic limit and fatigue limit. It can withstand large elastic deformation without permanent deformation. The L-shaped elastic rod 27 and the slot 28 can temporarily separate the retaining shaft 210 from the retaining groove 211, which facilitates the reset of the first housing 11 and the second housing 12.

[0027] Reference Figures 1 to 5 One end of the adjusting plate 23 is provided with a first straight groove 213 for the L-shaped elastic rod 27 to slide into the inner side of the slot 28, and one end of the adjusting plate 23 and the side opposite to the first straight groove 213 is provided with a second straight groove 212 for the L-shaped elastic rod 27 to separate from the slot 28.

[0028] Through this method of implementation: the first straight groove 213 will drive the locking shaft 210 to rotate upward, thereby driving the first mounting block 25 to rotate around the rotating shaft 24. At this time, the L-shaped elastic rod 27 installed at one end of the mounting shaft 26 will engage with the groove 28 through the rotation of the first mounting block 25. Then, pushing the second housing 12 will complete the reset with the first housing 11. When pushed to the inside of the second straight groove 212, it will drive the locking shaft 210 to rotate downward, thereby driving the first mounting block 25 to rotate downward and separating the L-shaped elastic rod 27 from the groove 28, so that the locking shaft 210 is reset into the groove 211.

[0029] Reference Figures 1 to 5 The edge of the card slot 211 near the first straight slot 213 is arc-shaped;

[0030] By implementing this method, the arc-shaped setting of one side of the guard will facilitate the pulling of the locking shaft 210, and increase the smoothness of the unfolding of the second housing 12 and the first housing 11.

[0031] Reference Figures 1 to 5 A sealing component 3 is provided inside the heat dissipation port 14 to increase the sealing performance. The sealing component 3 includes a sealing membrane 31 embedded inside the heat dissipation port 14. An insert block 32 is fixedly installed at the bottom end of the sealing membrane 31 and is embedded in the heat dissipation port 14. An insert groove 33 is opened inside the heat dissipation port 14 to be embedded in the insert block 32.

[0032] Through this method, the sealing membrane 31 is made of polytetrafluoroethylene microporous membrane, which is produced by a special stretching process. Its pore size is very small, generally between 0.1 and 10 μm. The diameter of dust particles and other impurities is usually between a few micrometers and tens of micrometers, which is much larger than the size of the micropores, so they cannot pass through. The sealing membrane 31 can increase the sealing performance and prevent external dust and larger particles from entering the casing body 1 and damaging the internal battery.

[0033] Reference Figures 1 to 5The sealing assembly 3 also includes a U-shaped sealing strip 34 fixedly installed at one end of the first housing 11, and a U-shaped sealing groove 35 adapted to the U-shaped sealing strip 34 is provided at one end of the second housing 12.

[0034] By implementing this method, the sealing performance of the housing body 1 can be increased when the first housing 11 and the second housing 12 are restored, thanks to the U-shaped sealing strip 34 and the U-shaped sealing groove 35.

[0035] Reference Figures 1 to 5 The first housing 11 has a mounting beam 13 fixedly installed on the inner side and fixedly installed on the top cover. The mounting beam 13 is symmetrically fixedly installed at both ends of the inner side of the first housing 11. The second housing 12 also has a mounting beam 13 symmetrically fixedly installed inside.

[0036] By implementing this method, the installation of the crossbeam 13 enables the housing body 1 and the cover plate to be installed.

[0037] The working principle of this utility model is as follows: When using the mounting housing body 1, firstly, adjust the distance between the first housing 11 and the second housing 12 according to the installation space. First, pull the second housing 12. When pulling the second housing 12, it will drive the first mounting block 25, which is rotatably connected to the outer circumference of the rotating shaft 24 at one end of the U-shaped unfolding plate 21, to move. When the first mounting block 25 is pulled, it will drive the locking shafts 210 at both ends of the second mounting block 29, which is fixed at one end, to move. Since the edge of one end of the slot 211 is arc-shaped, the locking shaft 210 will be adjusted inside multiple slots 211 through the first mounting block 25 and the rotating shaft 24 when it is pulled. When the adjustment is to the required size, stop pulling the second housing 12. At this time, the adjustment of the size between the second housing 12 and the first housing 11 is completed. The unfolding component 2 can adjust the size between the first housing 11 and the second housing 12 according to the installation space. The size is small enough to facilitate installation of the housing body 1 in different installation spaces. When it is necessary to restore the first housing 11 and the second housing 12, simply pull the second housing 12 towards the first straight groove 213. When the locking shaft 210 moves to the first straight groove 213, the first straight groove 213 will drive the locking shaft 210 to rotate upward, thereby driving the first mounting block 25 to rotate around the rotating shaft 24. At this time, the L-shaped elastic rod 27 installed at one end of the mounting shaft 26 will engage with the groove 28 through the rotation of the first mounting block 25. Then, the second housing 12 can be directly pushed towards the second straight groove 212. When pushed to the inside of the second straight groove 212, it will drive the locking shaft 210 to rotate downward, thereby driving the first mounting block 25 to rotate downward and separating the L-shaped elastic rod 27 from the groove 28, so that the locking shaft 210 is reset to the inside of the locking groove 211, thus completing the restoration of the first housing 11 and the second housing 12.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
