Description

Technical Field

[0001] The present invention relates to the technical field of energy storage batteries, and particularly to a wall-mounted household energy storage battery module. Background Art

[0002] A household energy storage battery module is a device that stores power supplied by solar energy, mains power, etc. and outputs it again for use; it includes structures such as a housing, a battery pack, a control board, and mounting parts, and the main body is generally rectangular in shape; it is mounted on vertical structures such as walls.

[0003] For example, the patent with the application number "CN2022225547934" discloses a wall-mounted household energy storage all-in-one machine; it includes a box body, a front cover plate, and a front baffle of the box body. The front cover plate and the front baffle of the box body are both mounted on the box body, and limiting buckles are provided on the outer sides of the front cover plate and the front baffle of the box body, and a limiting slot adapted to the limiting buckles is provided at the opening of the box body. The patent with the application number "CN2022219004589" discloses a wall-mounted energy storage battery system for household use with a light strip; it includes a box body and a box cover. An energy storage power supply mechanism is provided inside the box body, a mounting mechanism is provided on the back of the box body, and an anti-detachment mechanism is provided at the top of the back of the mounting mechanism. The patent with the application number "CN2021218346974" discloses a wall-mounted energy storage battery module; it includes a wall-mounted chassis and a battery module mounted inside the wall-mounted chassis; the wall-mounted chassis includes a box body for fixing the battery module, a panel mounted on the front of the box body, and a wall-mounted fixing strip mounted on the back of the box body.

[0004] The above disclosed solutions and the existing technologies in the market can all achieve household energy storage and supply for use. However, there are still some deficiencies and areas for improvement. For example, the battery pack and the control board are in the same space. Once a fire breaks out and the control board is damaged or destroyed, it will be unable to effectively activate fire protection measures; some fire protection structures are not provided inside some shells, or the fire protection structures are unreasonable and unreliable. In addition, the overall mass is relatively large, which is not convenient for operations such as moving and mounting on the wall, and the burden on personnel is heavy. Moreover, the modification operation is inconvenient, difficult to correspond to, or has a large volume and occupies a large space; and so on. Summary of the Invention

[0085] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0086] Referring to Figures 1 - 22 , a wall-mounted household energy storage battery module includes a housing 1 and a battery pack located inside the housing 1; the housing 1 is in the shape of a cuboid, and the interior of the housing 1 is formed with a top bin 11 and a battery bin 12 through a partition plate; the battery pack is placed in the battery bin 12, and components such as a control board are placed in the top bin 11. Separating the two can reduce the damage degree of the control system when an accident occurs to the battery pack, so as to achieve safer and more reliable control.

[0087] At the same time, a cabinet door 2 is provided on the front side of the housing 1; it is convenient to open for internal maintenance, repair and other operations to ensure that the equipment is in a more reliable and stable operating environment.

[0088] In some embodiments, handles 14 are provided on both sides of the top end of the housing 1; this facilitates personnel to lift the entire device using a reasonable structure.

[0089] Preferably, as Figure 1 shown; two handles 14 are symmetrically arranged on the left and right at the top.

[0090] In addition, the lower end of the housing 1 is provided with a reinforced bottom bin 13 with an open bottom; while forming a higher bottom strength and bearing capacity, the reinforced bottom bin 13 also forms a mounting position for the moving wheels; this facilitates auxiliary pushing and pulling movement on the ground, and the moving wheels can be removed during wall mounting without occupying extra space.

[0091] Preferably, two groups of threaded barrel seats 131 for installing and disassembling the moving wheels are symmetrically arranged inside the reinforced bottom bin 13 from left to right; correspondingly, the threaded shafts of the moving wheels are matched with them to achieve detachable installation.

[0092] Furthermore, as Figures 4 - 6 shown; radial reinforcing strips 132 are arranged around the outside of the threaded barrel seat 131, and coaxial reinforcing rings 133 are arranged; this can significantly improve the bearing strength; and, the reinforcing ring 133 cooperates with the threaded barrel seat 131 and the reinforcing strips 132, and its force-bearing form is more reliable.

[0093] In some embodiments, a fire extinguishing pipe 3 is arranged in the battery bin 12.

[0094] Among them, the interface of the fire extinguishing pipe 3 extends to the outside of the housing 1 to connect to an external supply.

[0095] Preferably, a one-way valve is arranged inside the interface of the fire extinguishing pipe 3 to avoid situations such as backflow.

[0096] It should be noted that when planning and arranging multiple energy storage battery modules, a set of external fire-fighting supply equipment can be used to connect all the fire extinguishing pipes 3 for unified supply; when only setting a single energy storage battery module, an external fire-fighting supply component can be directly set; and, the external fire-fighting supply and the energy storage battery module are in a split mode, which is also more convenient for overhauling, replacing, maintaining, etc. of the external fire-fighting supply.

[0097] Specifically, as Figures 13 - 14 shown; the fire extinguishing pipe 3 includes: a main pipe 31 arranged horizontally close to the top of the battery bin 12, and branch pipes 32 arranged vertically close to the inner walls on both sides of the battery bin 12 respectively.

[0098] One main pipe 31 is connected to two branch pipes 32 as a group; forming a "similar N-shaped" structure to achieve coverage of the top and sides of the battery bin 12, ensuring reliable, comprehensive, and effective coverage of the fire extinguishing surface.

[0099] Correspondingly, the main pipe 31 has a downward opening, and the branch pipe 32 has an inward opening.

[0100] It can be understood that the openings of the main pipe 31 and the branch pipe 32 are both oriented towards the battery pack and spray towards it.

[0101] Furthermore, both ends of the main pipe 31 penetrate through to one side of the housing 1 respectively and are provided with interfaces; check valves that only allow the fire extinguishing agent to lead to the interior are provided inside the interfaces of the main pipes 31 on both sides.

[0102] Thus, it is convenient to select a suitable orientation (left or right) to connect to the external supply during equipment layout.

[0103] Of course, it is also possible to connect to the external supply on both sides simultaneously.

[0104] Furthermore, two sets of fire extinguishing pipes 3 are arranged.

[0105] As Figure 13 shown; the two sets of fire extinguishing pipes 3 are arranged front and back to form a more reliable and comprehensive coverage.

[0106] Even further, two sets of fire extinguishing pipes 3 are arranged and are respectively connected to different external fire extinguishing agent supplies.

[0107] It should be noted that the fire extinguishing treatment for the battery pack is relatively complex. It not only needs to extinguish the flame but also needs to effectively cool the battery pack; in the present invention, two preset fire extinguishing agent supplies can respectively transport different types of fire extinguishing agents and be regulated during the fire extinguishing process to achieve more efficient and reliable operation.

[0108] It can be understood that the external fire protection supply is equipped with components such as pumping, pressurizing, and gas delivery to transport the fire extinguishing agent to the fire extinguishing pipe 3 at an appropriate pressure and speed.

[0109] In some embodiments, ventilation hole groups are respectively opened at the lower ends on both sides of the top compartment 11 and the battery compartment 12; natural ventilation and heat dissipation are realized during daily use.

[0110] Optionally, a fan is provided inside the housing 1 corresponding to the position of the ventilation hole group.

[0111] Preferably, a closing plate is correspondingly provided inside or outside the ventilation hole group to control the opening or closing of the ventilation hole group.

[0112] In some embodiments, the top of the housing 1 is open, and an integrated board box 111 is installed inside the opening.

[0113] Correspondingly, the lower end of the integrated board box 111 extends into the top compartment 11, and components such as a wiring seat and a socket are provided at the upper end.

[0114] It can be understood that the device is connected to the external input and output through the terminal block and socket on the integrated board box 111; by uniformly configuring each interface in an integrated board box 111, the overall design is more reasonable; and wiring and maintenance are more convenient.

[0115] Preferably, the upper end of the integrated board box 111 is also provided with buttons, warning lights, and other components.

[0116] It should be noted that a control board is provided in the integrated board box 111 to set up the above-mentioned components; accordingly, the integrated board box 111 is provided with wires to connect the battery pack; in addition, control boards with other functions need to be provided, which can be placed in the top compartment 11 accordingly; a wire hole is designed between the top compartment 11 and the battery compartment 12.

[0117] It is understandable that the control board and temperature monitoring module of the battery pack are arranged in the battery compartment 12.

[0118] In some embodiments, a display screen 21 , control buttons 22 and a card reading and writing module 23 are disposed on the door 2 .

[0119] The display screen 21 is used for information display, the control buttons 22 are used for operation and input, and the card reader / writer module 23 is used for information exchange.

[0120] Thus, identity authentication can be performed through the card reader module 23 to avoid unauthorized operations, such as reading and writing identity cards, tokens, etc. In addition, data interaction can also be performed through the card reader module 23, such as quickly inputting a set of configuration information through the card reader module 23.

[0121] That is to say, a configuration card is pre-set; the configuration card can record at least one set of configuration information, and the configuration card information is read by the card reader / writer module 23 to achieve unified configuration of the device.

[0122] In some embodiments, a heat dissipation component 4 extending into the interior is disposed at the rear end of the housing 1 to achieve efficient heat dissipation of the interior; and, the heat dissipation area is extremely large.

[0123] Specifically, the heat dissipation assembly 4 includes: a heat dissipation plate 41 with a front end located inside the shell 1 and a rear end located outside the shell 1 ; the heat inside is guided to the outside through the heat dissipation plate 41 .

[0124] Preferably, the rear end of the heat dissipation plate 41 protrudes from the rear end of the housing 1 .

[0125] It can be understood that the heat sink 41 covers the top compartment 11 and the battery compartment 12 ; and the battery pack is in contact with the heat sink 41 as much as possible.

[0126] like Figure 14 As shown; the upper end portion of the heat dissipation plate 41 is located in the top bin 11.

[0127] Further, heat dissipation fins 42 extending vertically are arranged in an array at the rear end of the heat dissipation plate 41.

[0128] By arranging the heat dissipation fins 42 in a vertically arranged form, it is more conducive to the upward flow of hot air; moreover, the dust adhesion on the heat dissipation fins 42 can be reduced.

[0129] Furthermore, horizontal through-holes 43 are formed on the heat dissipation fins 42 to form a horizontal air duct, which is conducive to the passage of the water bottle of air flow; the heat accumulation in the middle position can be reduced, and the heat dissipation operation is more reliable and efficient.

[0130] Furthermore, as Figures 6 - 8 shown; air supply ducts 5 corresponding to the heat dissipation fins 42 are vertically arranged on one side or both sides of the rear end of the housing 1; air outlet holes facing the heat dissipation fins 42 are formed on the air supply ducts 5.

[0131] Correspondingly, one end of the air supply duct 5 is closed, and the other end is connected to an external air supply component. It can be optionally opened irregularly or triggered by temperature to perform lateral air supply and accelerate heat dissipation; it can also clean the adhesion on the heat dissipation fins 42.

[0132] It can be understood that a temperature sensing module is provided inside the device; by monitoring the internal temperature, the operating state of the heat dissipation component 4 is controlled; for example, when the temperature reaches a certain threshold, the air supply duct 5 is started to perform lateral air supply, and only passive natural heat dissipation is relied on in daily life.

[0133] In some embodiments, a cooling coil 44 is embedded at the rear end of the heat dissipation plate 41.

[0134] Specifically, as Figures 10 - 11 shown; a slot is provided at the rear end of the heat dissipation plate 41, and a part of the cooling coil 44 is placed in the slot.

[0135] It should be noted that in the daily state, the cooling coil 44 does not need to operate; its partially embedded form forms an enlarged heat dissipation surface for natural heat dissipation; when the temperature reaches a certain threshold, the cooling cycle needs to be triggered.

[0136] It can be understood that interfaces are provided at the inlet and outlet ends of the cooling coil 44 and are connected to an external liquid supply device.

[0137] In this setting form, the part for strengthening heat dissipation (the cooling coil 44) is located outside the device. Even if a leakage or other situation occurs, it will not affect the internal components; and it can be discovered faster and the maintenance is more convenient.

[0138] In some embodiments, a liquid storage chamber 45 is integrally provided at the front end of the heat dissipation plate 41.

[0139] It should be noted that the liquid storage bin 45 bulges inward and enters the top bin 11 and the battery bin 12; as Figures 15 - 16 shown, there are corresponding notches on the partition plate.

[0140] Under normal conditions, the liquid storage bin 45 is filled with heat-conducting liquid, but it does not circulate, and natural heat conduction and heat dissipation are carried out; when the temperature reaches a certain threshold, the cooling cycle is triggered.

[0141] It can be understood that the liquid storage bin 45 is provided with liquid inlet and outlet pipes, which are connected to external liquid supply equipment; preferably, the liquid inlet and outlet pipes are arranged at the rear end of the heat dissipation plate 41.

[0142] It should be noted that the air supply pipe 5, the cooling coil 44, and the liquid storage bin 45 are in a coordinated form; according to the monitored internal temperature, one or more of them are started to operate to achieve reliable and effective temperature control.

[0143] In some embodiments, a top baffle 6 is detachably installed at the upper rear position of the housing 1.

[0144] It should be noted that the top baffle 6 is optional and is used to close the upper part to reduce the accumulation of dust on the heat dissipation component 4; there is a gap between the top baffle 6 and the top of the heat dissipation component 4, and the hot air flow can rise from both sides of the top baffle 6.

[0145] Specifically, a card rail 61 is arranged at the upper rear position of the housing 1;

[0146] The top baffle 6 is composed of a card board 62 and a baffle 63 arranged in an integrated T shape;

[0147] Thus, the card board 62 is horizontally inserted into the card rail 61 for installation or disassembly.

[0148] It should be noted that when the top baffle 6 is in the installed state, its rear end is closely attached to the wall.

[0149] Furthermore, a plurality of vertically penetrating air holes 64 are arranged in an array on the baffle 63 to allow the hot air flow to rise through.

[0150] Even further, the air holes 64 are in the shape of a conical hole with a larger lower opening and a smaller upper opening.

[0151] Thus, when the air flow below rises upward, an aggregation effect is formed and it is easy to pass through; and when the dust above falls, it is not easy to pass through; in addition, when the hot air flow below rises, a certain aggregation is formed, and the dust near the air holes 64 can also be blown away.

[0152] Preferably, the baffle 63 is made of hard rubber and has a certain deformation ability, and its end can fit more closely to the wall.

[0153] In some embodiments, a mounting member is provided at the rear end of the housing 1 to achieve wall mounting of the device.

[0154] Specifically, the mounting member includes a U-shaped card seat 7 for mounting on the wall and a card member 8 for mounting on the rear end of the housing 1.

[0155] As Figures 8 - 9 shown, both ends of the U-shaped card seat 7 have perforated ear plates; in the mounted state, the card member 8 is inserted into the raised space of the U-shaped card seat 7 from top to bottom.

[0156] Specifically, the card member 8 is composed of a mounting plate 81 for cooperating with the rear end of the housing 1, a connecting block 82 fixed to the rear end of the mounting plate 81, and two vertical clamping plates 83 that are parallel to each other and perpendicular to form a clamping space.

[0157] As Figure 21 shown; the connecting block 82 connects the mounting plate 81 and the two vertical clamping plates 83 into one body; the mounting plate 81 is a square flat plate provided with bolt holes for assembling with the rear end of the housing 1; the connecting block 82, as a directly stressed structure, should have an appropriate thickness to ensure strength; the two vertical clamping plates 83 form a clamping state, and the thickness of the clamping space at their inner ends should be greater than the material thickness of the U-shaped card seat 7.

[0158] Furthermore, the lower end of the rear vertical clamping plate 83 is lower than the lower end of the front vertical clamping plate 83; or, the lower end of the rear vertical clamping plate 83 is higher than the lower end of the front vertical clamping plate 83; thus, the lower ends of the two vertical clamping plates 83 are misaligned, making the operation more convenient, fast, and simple when aligning and placing.

[0159] Even further, as Figures 17 - 21 shown; the opposite surfaces of the lower ends of the two vertical clamping plates 83 are set as inclined surfaces or arc surfaces, which is more conducive to alignment and snapping in.

[0160] In some embodiments, the upper end of the connecting block 82 is an inclined surface that is higher at the front and lower at the rear; it has a more reasonable and higher-strength stress form.

[0161] Furthermore, a through hole corresponding to the clamping space of the two vertical clamping plates 83 is provided on the connecting block 82; a vertical insertion block 71 is provided at the middle position above the U-shaped card seat 7; the vertical insertion block 71 penetrates to the upper end of the through hole of the connecting block 82.

[0162] It can be understood that the cooperation between the card member 8 and the U-shaped card seat 7 mainly controls the up and down movement, but the left and right displacement is not stable enough (the width of the card member 8 should be smaller than the width of the clamping space of the U-shaped card seat 7, having a certain movement space, otherwise it will be too difficult to install correspondingly); thus, the through hole and the vertical insertion block 71 are provided in cooperation to further improve the stability of the hanging installation.

[0163] It should be noted that, for the convenience of alignment, the top end of the vertical insertion block 71 is set in an arc shape or with rounded edges.

[0164] When hanging and installing, the U-shaped card holder 7 is pre-installed on the wall; then, after the card member 8 is basically aligned, it is inserted from top to bottom; it should be noted that there are no less than 4 hanging and installing members to control the level and ensure stable installation and reliable connection.

[0165] In some embodiments, it further includes: a gravity locking member that cooperates with the hanging and installing member.

[0166] It can be understood that relying on the gravity of the device itself, a stable form can be formed through the hanging and installing member; however, after all, it is in an unlocked state; if it is subjected to an external force from below or obliquely upward, it may cause detachment.

[0167] Therefore, we set a gravity locking member to form a completely locked state.

[0168] Specifically, the gravity locking member is composed of: a guide cylinder 84 fixedly arranged at the upper end of the connecting block 82, and a pin rod 85 slidably arranged in the guide cylinder 84; the vertical insertion block 71 is provided with a socket corresponding to the moving direction of the pin rod 85; under the action of gravity, the pin rod 85 slides downward and inserts into the socket of the vertical insertion block 71.

[0169] Furthermore, a magnetic attraction strip 86 is arranged at the upper end of the pin rod 85; so as to assist in pulling out the pin rod 85 upward through structures such as a magnetic force rod, so that it disengages from the socket of the vertical insertion block 71.

[0170] It should be noted that, in the natural state, a part of the lower end of the pin rod 85 is located above the through hole of the connecting block 82 and does not exceed one-half; when hanging and installing, the arc / slant surface of the vertical insertion block 71 touches the pin rod 85 and makes it move upward along the guide cylinder 84 by a certain distance; then, after reaching the position, the pin rod 85 corresponds to the socket of the vertical insertion block 71 and slides into the socket under gravity; at this time, due to the inclined shape of the socket, the pin rod 85 cannot be pushed again, realizing locking. When disassembly is required, a structure such as a magnetic force rod is used to generate a suction force on the magnetic attraction strip 86, and then the pin rod 85 is pulled out upward and disengages from the socket of the vertical insertion block 71.

[0171] It can be understood that the gravity locking member can be set on the two hanging and installing members at the topmost position, and there is no need to set the hanging and installing members at the lower positions; as Figure 7 shown, the four hanging and installing members form upper and lower groups; the hanging and installing members in the upper group are provided with force locking members.

[0172] In some embodiments, a plurality of elastic positioning feet 9 are arranged at the rear end of the housing 1 to assist in the hanging and installing operation.

[0173] It is understandable that when hanging, the clamp 8 needs to be aligned with the U-shaped clamp 7; because there must be a certain gap between the rear end of the clamp 8 and the wall, and there must be a certain matching gap between the clamp 8 and the U-shaped clamp 7, it is difficult to accurately control the distance between the rear end and the wall during alignment; and the distance between it and the wall is small, and it is not easy to check and locate; and it may happen that after finally aligning one, the others cannot be aligned; when aligning the next one, the previous one is misaligned; and so on. Therefore, we specially designed an auxiliary structure.

[0174] like Figure 7 As shown; there are no less than four elastic positioning feet 9; on the basis of forming a balance of distance between the fulcrums at various locations, it can also correspond to the position of the card 8 (this correspondence is not necessary).

[0175] Specifically, the elastic positioning foot 9 is composed of an outer tube 91 and an inner tube 92 in a sleeve-like form; the inner tube 92 is slidably matched with the outer tube 91 , and a spring is arranged in the outer tube 91 to push the inner tube 92 outward.

[0176] Under the action of the spring, the inner cylinder 92 is pushed backwards, and the elastic positioning foot 9 is in an extended state. When the elastic positioning foot 9 is in the maximum compression state under pressure, the inner cylinder 92 presses against the wall, and the clamping space of the vertical clamping plate 83 corresponds to the U-shaped card seat 7.

[0177] When hanging, align the upper and lower positions in advance, press several elastic positioning feet 9 against the wall, and apply force to press; then, move the whole downward, and each clamp 8 can accurately enter the U-shaped clamp seat 7.

[0178] Furthermore, in order to facilitate movement under pressure, the top end of the inner tube 92 is configured to be spherical, with a smaller sliding resistance against the wall.

[0179] When the present invention is used, the positions of several U-shaped holders 7 are positioned on the wall with high precision in advance; after the components of the equipment are installed and checked for correctness, the holder 8 is matched with the U-shaped holder 7 and hung on the wall; then the top baffle 6 is inserted, or the top baffle 6 is pre-installed; wiring is connected through the integrated board box above; and the components on the box door 2 are adjusted and configured; during use, the internal temperature and abnormal conditions are monitored at all times, and when different strategies of cooling are required, the air supply duct 5, cooling coil 44, and liquid storage tank 45 are controlled to cooperate with each other; when firefighting operations are required, the fire extinguishing agent is delivered through the fire extinguishing pipe 3; at the same time, the warning light set on the top is illuminated to remind.

[0180] In the present invention, internal partitions are formed to create a top compartment 11 and a battery compartment 12. Components such as the control board are placed in the top compartment 11, which can reduce the damage to the control system when an accident occurs to the battery pack and achieve safer and more reliable control. The interface of the fire extinguishing pipe 3 extends to the outside of the housing 1 to connect to an external supply. The external fire supply and the energy storage battery module are in a split mode, which is more convenient for overhaul, replacement, maintenance, etc. of the external fire supply. The integrated board box 111 is installed at the top opening, and various interfaces are configured together, making the overall design more reasonable. A heat dissipation component 4 extending to the inside is provided at the rear end to achieve efficient heat dissipation inside, with a large heat dissipation area. The air supply pipe 5, the cooling coil 44, and the liquid storage chamber 45 cooperate with each other to achieve reliable and effective temperature control. A top baffle 6 is detachably installed at the upper position to reduce the accumulation of dust on the heat dissipation component 4. A vertically penetrating air hole 64 is opened to allow hot air to rise through. The air hole 64 is in the shape of a conical hole with a larger lower opening and a smaller upper opening. When the air flow passes upward from below, an aggregation effect is formed. When the dust above falls, it is not easily passed through. The hanging member includes a U-shaped card seat 7 and a card member 8. A gravity locking member cooperating with the hanging member is provided to form a completely locked state. A plurality of elastic positioning feet 9 are provided to assist in the hanging operation.

[0181] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
