[0031] An embodiment of the utility model relates to a dual-mode energy storage power supply, which has a portable energy storage mode and a household energy storage mode, and includes: a shell; a handle, which is arranged on the shell; a plurality of rollers, which are arranged on the bottom of the shell; a pull rod assembly, which is retractably arranged on the shell; a battery pack, which is arranged inside the shell; a metal frame, which is arranged inside the shell and is used to support the shell and carry the battery pack; a control assembly, which is arranged inside the shell, and the control assembly includes a power management module, a bidirectional inverter and a DC control module, the power management module is electrically connected to the battery pack and the bidirectional inverter, and is used to control the charging and discharging of the battery pack; the bidirectional inverter is used to support the AC charging, AC discharging, DC charging, DC discharging, AC parallel connection and grid connection functions of the dual-mode energy storage power supply; the bidirectional inverter also includes a DC power module, the DC power module is electrically connected to the DC control module, and the DC control module is used to adjust the DC charging power and DC discharging power of the dual-mode energy storage power supply.

[0033] The implementation details of the dual-mode energy storage power supply of this embodiment are specifically described below. The following content is only provided for easy understanding of the implementation details and is not necessary for implementing this solution.

[0034] See also Figures 1 to 7The dual-mode energy storage power supply 100 in this embodiment includes: a housing 110, a handle 120, a plurality of rollers 130, a rod assembly 140, a battery pack 190 and a metal frame 150. The handle 120 is provided on the housing 110, the plurality of rollers 130 are provided at the bottom of the housing 110, the rod assembly 140 is telescopically provided on the housing 110, the battery pack 190 is provided inside the housing 110, and the metal frame 150 is provided inside the housing 110 for supporting the housing 110 and carrying the battery pack 190. The dual-mode energy storage power supply 100 further includes a control assembly 160, which is disposed inside the housing 110. The control assembly 160 includes a power management module 161, a bidirectional inverter 162, and a DC control module 163. The power management module 161 is electrically connected to the battery pack 190 and the bidirectional inverter 162, and is used to control the charging and discharging of the battery pack 190. The bidirectional inverter is used to support the AC charging, AC discharging, DC charging, DC discharging, AC parallel connection, and grid connection functions of the dual-mode energy storage power supply 100. The bidirectional inverter 162 further includes a DC power module 1621, which is electrically connected to the DC control module 163, and the DC control module 163 is used to adjust the DC charging power and DC discharging power of the dual-mode energy storage power supply 100.

[0035] The DC power module 1621 can be integrated into the bidirectional inverter 162, thereby simplifying the overall structure of the control assembly 160, reducing its volume, and facilitating the utilization of the internal space of the dual-mode energy storage power supply 100, as well as facilitating the design of the internal wiring of the device. In addition, the DC power module 1621 can support DC charging and DC discharging of a high-power wide-voltage platform.

[0036] In this embodiment, a plurality of rollers 130 are arranged at the bottom of the housing 110, and a retractable pull rod assembly 140 is arranged, and the handle 120 is arranged for easy carrying. Through the bidirectional inverter 162 and the DC control module 163, the dual-mode energy storage power supply 100 has two discharge modes of AC and DC with adjustable power. The dual-mode energy storage power supply 100 can also support DC parallel operation, AC parallel operation and grid connection functions, that is, it can be powered by a single power supply, and can also be powered by multiple power supplies through parallel operation, so that it can support the low-power usage mode in the portable power application scenario, and can also support the high-power usage mode in the household energy storage power application scenario, so that the dual-mode energy storage power supply has the advantages of large power of traditional household energy storage power supply and portability of portable power supply.

[0037] It should be noted that in Figure 3In the figure, a solid arrow can represent a power connection (physical connection), such as an electrical connection using a wire, and a bidirectional arrow indicates that two modules can send electrical signals to each other and receive electrical signals sent by each other. A dotted arrow indicates that there is a communication connection between modules, that is, one module can send a control signal to another module.

[0038] Further, in this embodiment, the housing 110 is described as being in a hexahedral shape as a whole. It is understandable that in order to meet the application requirements of some special scenarios, the housing 110 can also be set to other shapes. Optionally, the rod assembly 140 can be located on the upper side, lower side, left side, right side, front side or rear side of the dual-mode energy storage power supply 100, and the rod assembly 140 is set on the rear side of the dual-mode energy storage power supply 100 as an example for description.

[0039] In this embodiment, the shell 110 is made of a composite plastic mixed with fireproof grade ABS plastic and fireproof grade PC plastic. Among them, ABS plastic is a terpolymer of three monomers: acrylonitrile, butadiene and styrene. It is corrosion-resistant, heat-resistant and has a certain hardness. It also has good elasticity and toughness, is not easy to break, is easy to process, and has good electrical properties. The shell 110 of the dual-mode energy storage power supply 100 is made of fireproof grade material. When the battery pack catches fire or the external environment catches fire, the shell 110 can play a good isolation role.

[0040] It can be understood that the rod assembly 140 includes a telescopic rod formed by connecting multiple sections of connecting rods in sequence, one end of the telescopic rod is fixed to the housing 110, and the other end is a free end. By stretching the telescopic rod to extend the length of the telescopic rod, it is convenient for the user to move the dual-mode energy storage power supply 100 through the roller 130 and the rod assembly 140. When there is only one telescopic rod, a cross arm can be fixed to the free end of the telescopic rod, and the rod assembly 140 is T-shaped as a whole. Alternatively, a pull ring can be fixed to the free end of the telescopic rod, and the user can pull the dual-mode energy storage power supply 100 by holding the cross arm or the pull ring. When the user does not need to move the dual-mode energy storage power supply 100, the telescopic rod can be retracted, so that the rod assembly 140 is retracted, reducing the occupied space of the dual-mode energy storage power supply 100.

[0041] Furthermore, a storage groove 111 can be formed on the outer side of the shell 110, and the storage groove 111 can accommodate the telescopic rod when the telescopic rod is retracted, thereby preventing the telescopic rod from protruding relative to the shell 110. The overall appearance of the dual-mode energy storage power supply 100 is flat and regular, making the appearance of the dual-mode energy storage power supply 100 more beautiful.

[0042] In this embodiment, a locking structure (not shown in the figure) may be provided in the storage groove 111. When the cross arm or the pull ring is completely received in the storage groove 111, the locking structure may lock the cross arm or the pull ring. Thus, when carrying or transporting the dual-mode energy storage power supply 100, the cross arm or the pull ring may be prevented from bouncing and causing collision, and abnormal noise may also be avoided.

[0043] It should be noted that each connecting rod in the telescopic rod can support two-way locking, which is convenient for users of different heights to pull and stop during use.

[0044] In this embodiment, grooves 113 are respectively provided on both sides of the top of the housing 110, and the handles 120 are provided on the inner walls of the grooves 113 in a one-to-one correspondence. A foot pad 114 is provided at the bottom of the housing 110, and the foot pad 114 is used to support the housing 110. When the dual-mode energy storage power supplies 100 are stacked in the height direction, the foot pad 114 of the dual-mode energy storage power supply 100 located at the top is embedded in the groove 113 of the dual-mode energy storage power supply 100 located at the bottom.

[0045] Specifically, the grooves 113 can be distributed on the front and rear sides or the left and right sides of the shell 110. The grooves 113 are arranged on the left and right sides of the shell 110. The surface of the handle 120 away from the grooves 113 is flush with the surface of the shell 110, making the shell 110 flat as a whole, more beautiful, and also convenient for stacking. There are four foot pads 114, which are respectively arranged at the four corners of the bottom of the shell 110. When multiple dual-mode energy storage power supplies 100 are stacked in the vertical direction, the two foot pads 114 located on the left side of the bottom of the shell 110 extend into the left groove 113 of the dual-mode energy storage power supply 100 located below, and the two foot pads 114 located on the right side of the bottom of the shell 110 extend into the right groove 113 of the dual-mode energy storage power supply 100 located below. In this way, the contact area of ​​the upper and lower dual-mode energy storage power supplies 100 can be increased when stacked, and the groove 113 of the dual-mode energy storage power supply 100 below can also be used to limit the foot pad 114 of the dual-mode energy storage power supply 100 above, thereby improving the stability of the stacking of multiple power supplies. At the same time, the overall stacked power supply group is more regular, flat and beautiful.

[0046] Furthermore, the side wall of the groove 113 is provided with heat dissipation holes, and a heat dissipation fan is provided inside the shell 110. When the dual-mode energy storage power supply 100 is working (i.e., charging and discharging), the heat dissipation fan generates air flow between the shell 110 and the outside to ventilate and take away heat, thereby achieving heat dissipation.

[0047] In this embodiment, the material of the foot pad 114 is TPU (thermoplastic polyurethane). When multiple power supplies are placed or battery products are stacked, all weight will eventually be applied to the foot pad 114 of the dual-mode energy storage power supply 100 at the bottom. TPU can provide higher hardness, thereby reducing the deformation of the foot pad 114 under gravity, better supporting the dual-mode energy storage power supply 100, and providing sufficient friction and buffering. For the convenience of showing the bottom metal plate 151 and the metal column 152, Figure 1 The bottom portion of the housing 110 is not shown, and the connection portion between the foot pad 114 and the housing 110 is not shown either.

[0048] In this embodiment, a soft rubber layer is provided on the surface of the handle 120 facing the groove 113 , which can effectively improve the hand comfort of the user when carrying the dual-mode energy storage power supply 100 through the handle 120 .

[0049] In this embodiment, there are two rollers 130, which are respectively arranged on the left and right sides of the bottom of the housing 110. The inner sides of the two rollers 130 are both flat, so that when the dual-mode energy storage power supply 100 is moved outdoors, foreign objects such as soil and weeds can be prevented from being entangled or blocked on the inner side of the roller 130, and even if there are foreign objects on the inner side of the roller 130, it is easy to clean. Further, at the location where the roller 130 is arranged, the surface of the housing 110 facing the roller 130 is also arranged to be flat.

[0050] Furthermore, a decorative cover is provided on the outer side of the roller 130, which can cover the rim of the roller 130 and the fasteners of the roller 130 and make the appearance of the dual-mode energy storage power supply 100 more beautiful. When necessary, a specific pattern or text can be set on the decorative cover to achieve personalized appearance settings and enhance the recognition of the dual-mode energy storage power supply 100.

[0051] In this embodiment, when the dual-mode energy storage power supply 100 is in a stationary state, the roller 130 is in a suspended state and is not in contact with the ground, which can improve the stability of the dual-mode energy storage power supply 100 when it is stationary.

[0052] In some other embodiments, the roller 130 may be a universal wheel to facilitate the user to turn when moving the dual-mode energy storage power supply 100.

[0053] In this embodiment, since the battery pack of the dual-mode energy storage power supply 100 has a large battery capacity, and the bidirectional inverter 162 enables the dual-mode energy storage power supply 100 to realize the grid-connected function without an external inverter, when the dual-mode energy storage power supply 100 is connected to a photovoltaic system or other power generation system, efficient management and utilization of electricity can be achieved. For example, the electric energy generated by the household photovoltaic system can be directly supplied to household electrical appliances through the DC power module 163 on the dual-mode energy storage power supply 100. The excess electricity can also charge the battery pack 190 inside the dual-mode energy storage power supply 100, or be incorporated into the power grid to supply power to the power grid. When the dual-mode energy storage power supply 100 supplies power to the power grid, the electric meter can be reversed, thereby reducing the electricity cost for users, and even generating revenue by supplying power to the power grid. In this embodiment, the DC power module 163 supports DC charging and DC discharging of a wide voltage platform, increasing the user's benefit.

[0054] It is understandable that, when necessary, the dual-mode energy storage power supply 100 can also be connected to an external inverter to achieve power supply and grid connection.

[0055] Among them, the dual-mode energy storage power supply 100 also includes an AC discharge interface 1624 electrically connected to the bidirectional inverter 162. The AC discharge interface 1624 can be multiple, and each complies with different national standards to meet the application requirements of different countries and regions. In addition, the dual-mode energy storage power supply 100 also includes a DC discharge interface electrically connected to the DC power module 163. The DC discharge interface includes a USB-A interface, a USB-C interface, a cigarette lighter female plug, an Anderson interface, and a DC5521 interface. In addition, these interfaces also support high-power discharge. Among them, the cigarette lighter female plug and the Anderson interface support multi-voltage platform switching to meet the power requirements of more devices. At the same time, a protective cover is provided on the outside of the DC discharge interface, which can be dustproof and waterproof, realize electrical protection of the socket, and play a certain aesthetic role.

[0056] It can be understood that the dual-mode energy storage power supply 100 also includes a DC charging interface 1622 electrically connected to the DC power module 1621, and an AC charging interface 1625 electrically connected to the bidirectional inverter 162. The DC charging interface 1622 supports a wide voltage platform and can also support DC charging equipment and photovoltaic charging equipment. An overcurrent protector is provided at the AC charging interface to prevent excessive charging current from damaging electrical components. At the same time, a protective cover 112 can be provided on the outside of the charging interface to prevent dust and water, realize electrical protection of the socket, and play a certain aesthetic role. In addition, the AC charging interface 1625 can also be used as a grid-connected interface.

[0057] In this embodiment, the dual-mode energy storage power supply 100 further includes an AC parallel module 164 electrically connected to the bidirectional inverter 162, and the AC parallel module 164 has at least one AC parallel port (not shown in the figure), and the AC parallel port is an AC parallel port capable of AC charging and / or AC discharging. The AC parallel port can be a bidirectional port capable of AC charging and AC discharging, and the number can be one or more; or, the AC parallel port can be composed of an independent AC charging unidirectional port and an AC discharging unidirectional port, and both the AC charging unidirectional port and the AC discharging unidirectional port can be one or more. In this way, multiple groups of power supplies can be connected to the control box of the home through the AC parallel port, and each power supply can be connected to multiple power supplies or battery products, thereby achieving greater power reserve and power output, and can also achieve UPS (uninterruptible power supply) function. It can be understood that the power supply in the "multiple groups of power supplies" can be the dual-mode energy storage power supply 100 of this embodiment, or other power supply equipment. Further, a protective cover 112 is provided on the outside of the AC parallel port, which can be dustproof and waterproof, realize electrical protection of the socket, and play a certain aesthetic role.

[0058] It can be understood that when the AC parallel port can support AC charging and AC discharging at the same time, it can realize the functions of the AC charging interface 1625, the AC discharging function and the parallel function, that is, at this time the AC charging / discharging interface and the AC parallel port are the same interface, which can further optimize the internal circuit layout and external interface layout of the dual-mode energy storage power supply 100.

[0059] In this embodiment, the dual-mode energy storage power supply 100 also includes a DC parallel module 165 electrically connected to the power management module 161, and the DC parallel module 165 has at least one DC parallel port (not shown in the figure), and the DC parallel port is a DC parallel port capable of DC charging and / or DC discharging. The DC parallel port can be a bidirectional port capable of DC charging and DC discharging, and the number can be one or more; or, the DC parallel port can be composed of an independent DC charging unidirectional port and a DC discharging unidirectional port, and the DC charging unidirectional port and the DC discharging unidirectional port can be one or more. In this way, the above-mentioned DC parallel port can be used to connect multiple DC power supplies in series or in parallel to provide a power supply with greater power or current to meet different usage requirements.

[0060] In addition, multiple adapters that comply with other national standards can be configured according to actual conditions, and / or multiple sockets that comply with other national standards can be set on the housing 110 to meet the charging or electricity needs of different countries or regions, especially to match the high-power charging of car charging piles, improve charging efficiency, and reduce the user's charging waiting time.

[0061] In this embodiment, the dual-mode energy storage power supply 100 also includes a parallel adjustment port electrically connected to the power management module 161, and the parallel adjustment port includes multiple COM-1 interfaces, multiple COM-2 interfaces, multiple COM-3 interfaces and multiple dip switches. The COM-1 interface is used for debugging and control of the home energy storage mode, the COM-2 interface is used for debugging and control of power supplies and battery products, the COM-3 interface is a dry contact for extending a variety of dry contact signals, and the dip switch is used to support manual encoding of the home energy storage mode.

Furthermore, the parallel adjustment port is also provided with a protective cover 112, which can be dustproof and waterproof, realize electrical protection of the socket, and play a certain aesthetic role.

[0062] In this embodiment, the dual-mode energy storage power supply 100 also includes a wireless communication module (not shown in the figure) provided on the DC control module 163, and the wireless communication module is used to communicate with the smart terminal, receive signals sent by the smart terminal, and send signals to the smart terminal. For example, the wireless communication module can be electrically connected / communicated with a smart phone or a tablet computer, and send signals to these smart terminals. The user can query the current working status of the bidirectional energy storage power supply 100 through the smart terminal, and control the dual-mode energy storage power supply 100 through these smart terminals, such as turning on the dual-mode energy storage power supply 100 for power supply, or remotely suspending charging, or changing its charging or discharging mode, etc. In other examples, the dual-mode energy storage power supply 100 can also be connected to a remote controller for communication.

[0063] Optionally, the wireless communication module is one or more of a Bluetooth module, a WiFi module, an RF communication module, a cellular communication module, a ZigBee communication module, and an infrared communication module. ZigBee communication is a new type of wireless communication technology with the advantages of low power consumption, low cost, support for a large number of online nodes, support for a variety of online topologies, low complexity, reliability and security, etc.

[0064] In this embodiment, the dual-mode energy storage power supply 100 further includes a fire extinguishing device (not shown in the figure), which is arranged inside the housing 110 and is used to extinguish the dual-mode energy storage power supply 100 when the dual-mode energy storage power supply 100 catches fire, so as to mitigate or eliminate the fire.

[0065] Furthermore, the fire extinguishing device includes a first temperature sensor and a chemical reactor, the first temperature sensor and the chemical reactor are both electrically connected to the DC control module 163, the first temperature sensor is used to detect the temperature of the battery pack, and the chemical reactor is used to perform a chemical reaction under the control of the DC control module 163 to produce a substance that inhibits combustion when the temperature of the battery pack 190 exceeds a preset value. Specifically, the temperature sensor can be set on the battery pack to monitor the temperature of the battery pack 190 in real time or intermittently, and send information corresponding to the detected temperature value to the DC control module 163. When the DC control module 163 determines that the temperature of the battery pack 190 exceeds the preset value, it is determined that the battery pack 190 is on fire. At this time, the DC control module 163 starts the chemical reactor, and the chemical substances in the chemical reactor react to generate a large amount of inert gas and trace solid particles, which are sprayed around the battery pack. The inert gas can isolate the battery pack from contact with the air, so that the battery pack cannot burn.

[0066] In some embodiments, the battery pack 190 includes a second temperature sensor (not shown) electrically connected to the DC control module 163, the chemical reactor is electrically connected to the DC control module 163, the second temperature sensor is used to detect the temperature of the battery pack 190, and the chemical reactor is used to perform a chemical reaction under the control of the DC control module to produce a substance that inhibits combustion when the temperature of the battery pack exceeds a preset value. Specifically, the second temperature sensor sends the detected information corresponding to the temperature of the battery pack 190 to the DC control module 163, and when the DC control module 163 determines that the temperature of the battery pack 190 exceeds the preset value, the DC control module 163 starts the chemical reactor.

[0067] In some embodiments, the dual-mode energy storage power supply 100 can be provided with the above-mentioned first temperature sensor and second temperature sensor at the same time, and different temperature sensors can be used to detect the temperature of the battery pack 190, which can not only make the detection result more accurate, but also can use the other temperature sensor for detection when one of the temperature sensors fails, thereby improving the safety performance of the dual-mode energy storage battery 100.

[0068] Furthermore, the fire extinguishing device may also be provided with a thermistor wire connected to the chemical reactor, and the thermistor wire is also attached to the battery pack 190, for example, wound around the battery pack 190, and the thermistor wire is used to trigger the chemical reactor to perform a chemical reaction when the temperature of the battery pack 190 exceeds a preset value, thereby producing a substance that inhibits combustion. The thermistor wire can be set to burn at a specific temperature, for example, 180°C. When the temperature of the battery pack 190 reaches 180°C, the thermistor wire burns, thereby triggering the chemical reactor to react. In this way, even if the above-mentioned first temperature sensor and the second temperature sensor fail, the thermistor wire can be used to achieve fire extinguishing, further improving the safety of the dual-mode energy storage power supply 100.

[0069] In practical applications, the thermistor wire can be selected to have different lengths according to the type and size of the battery pack 190. The thermistor wire is wrapped around the periphery of the battery pack 190 to detect the temperature of multiple different points of the battery pack 190. As long as the temperature of any point is higher than a preset value, the thermistor wire will burn, causing the chemical reactor to react and the fire extinguishing device to start extinguishing the fire. It is understandable that the first temperature sensor and the second temperature sensor can also detect the temperature of multiple different points of the battery pack 190.

[0070] In some embodiments, the chemical substances in the chemical reactor undergo chemical reactions to absorb a large amount of heat, thereby reducing the temperature of the battery pack. By providing a fire extinguishing device, the combustion reaction of the battery pack can be suppressed, thereby achieving the effect of extinguishing or delaying a fire.

[0071] More specifically, the fire extinguishing device can be a hot aerosol fire extinguishing device, and its fire extinguishing agent is a solid energetic chemical substance, which belongs to pyrotechnic agents. The fire extinguishing device uses redox reaction to start the activation of the fire extinguishing agent, so that it undergoes a chemical reaction, which can produce a large amount of inert gas, water vapor and trace solid particles to form a mixed gas. The mixed gas is released / sprayed outward from the nozzle of the automatic fire extinguishing device to produce a large amount of aerosol (mixed smoke) to inhibit the combustion reaction, thereby achieving the purpose of extinguishing the fire. The fire extinguishing mechanism of the above-mentioned fire extinguishing device is a full flooding fire extinguishing form that is carried out simultaneously by three fire extinguishing methods: physical, chemical, and water vapor cooling. Among them, "suffocation fire extinguishing" is achieved by physically diluting the oxygen in the air, which is the main fire extinguishing method, cutting off the flame reaction chain, destroying the combustion conditions of the flame, and rapidly reducing the concentration of free radicals. The chemical fire extinguishing method is achieved by the chemical substances that inhibit combustion produced by the reaction. At the same time, the water vapor produced by the reaction can take away heat by condensation and vaporization to reduce the temperature of the burning object.

[0072] It should be noted that the aerosol / smoke generated after the above-mentioned fire extinguishing device is activated is a non-toxic, non-hazardous, non-corrosive substance that does not deplete the atmosphere. In addition, the above-mentioned fire extinguishing device and the fire alarm controller are networked to achieve high-speed, efficient and comprehensive fire extinguishing. The entire fire extinguishing device system has no pipe network, no pressure vessel drive device, valves and pipelines, etc., which can save the use area and engineering costs. In addition, the fire extinguishing device is solid and leak-free, works under normal pressure, is safe and reliable, and is easy to store and transport.

[0073] In this embodiment, the battery pack is a lithium-ion battery pack. Compared with other battery packs, the lithium-ion battery pack has a high energy density and a small weight, which is conducive to realizing large-capacity energy storage of the dual-mode energy storage power supply 100 and improving its portability.

[0074] Furthermore, a metal frame (not shown in the figure) is disposed inside the housing 110 to improve the load-bearing capacity of the housing 110 , which is conducive to arranging a battery pack of a larger volume in the housing 110 .

[0075] Specifically, the metal frame includes an upper metal plate, a bottom metal plate 151 and a plurality of metal columns 152. The upper metal plate and the bottom metal plate 151 are spaced apart and connected in the middle by the metal columns 152. The battery pack is arranged between the upper metal plate and the bottom metal plate 151. It can be understood that the metal frame not only enables the housing 110 to better support and protect the battery pack, but also makes the external strength of the dual-mode energy storage power supply 100 higher, which is conducive to stacking multiple power supplies.

[0076] In this embodiment, the dual-mode energy storage power supply 100 further includes a lighting lamp, and a lighting lamp groove is provided on the top of the housing 110, and the lighting lamp is rotatably arranged in the lighting lamp groove. The lighting lamp includes a lamp housing 170 and a lamp tube, and when the lighting lamp is rotated and the lamp tube enters the lighting lamp groove, the outer surface of the lamp housing 170 is flush with the outer surface of the housing 110. With such an arrangement, when the lighting lamp is folded, the appearance of the dual-mode energy storage power supply 100 is flat and beautiful.

[0077] In this embodiment, the lighting lamp adopts a magnetic induction design, that is, a magnetic switch. When the user rotates the lighting lamp so that the lamp tube is exposed from the lighting lamp slot, the lighting lamp is powered on and emits light. Further, the rotation of the lighting lamp is realized by a rotating mechanism disposed inside the lighting lamp slot and pivotally connected to the lamp housing 170, wherein a damping structure is disposed between the rotating mechanism and the lamp housing 170, so that the lighting lamp can hover at any angle between 0° and 90°. For example, two relatively disposed rotating shafts are disposed in the lighting lamp slot, and shaft-accommodating holes / shaft-accommodating grooves are disposed at opposite ends of the lamp housing 170. The two rotating shafts extend into the shaft-accommodating holes / shaft-accommodating grooves one by one, and the shaft-accommodating holes / shaft-accommodating grooves and the rotating shafts are in frictional contact. When the lamp housing 170 is rotated, the friction between the inner wall of the shaft-accommodating holes / shaft-accommodating grooves and the rotating shaft enables the lighting lamp to hover at any rotation angle. Specifically, the inner wall of the shaft-containing hole / shaft-containing groove and the side wall of the rotating shaft can be set to be relatively rough to increase the friction coefficient, or a rubber ring can be set between the shaft-containing hole / shaft-containing groove and the rotating shaft. The rubber ring is used to increase friction, while improving stability and reducing noise that may be generated during rotation.

[0078] It is understandable that the rotating shaft can also be set at the opposite ends of the lamp housing 170, and the above-mentioned shaft-accommodating holes / shaft-accommodating grooves can be set at the opposite sides of the lighting lamp groove, and the rotating shafts on the lamp housing 170 can extend into the shaft-accommodating holes / shaft-accommodating grooves one by one.

[0079] In some embodiments, a self-locking structure can be provided on the lighting lamp. When the user turns the lighting lamp and retracts the lighting lamp into the lighting lamp slot, the self-locking structure can lock the lighting lamp, thereby preventing the dual-mode energy storage power supply 100 from making abnormal noises during transportation or pulling.

[0080] In this embodiment, a control panel and / or a display screen 180 can be set on the front or top of the housing 110. When the display screen 180 is set, the display screen 180 can be set as a touch screen so that it has the function of a control panel. The display screen 180 can display the charge and discharge power, charge and discharge time, remaining power, grid connection status, parallel state, high and low temperature state, OTA upgrade state, fan working state, wireless connection state, alarm and error code state and other information of the dual-mode energy storage power supply 100. Through the display screen 180, the DC discharge interface 1623, the AC discharge interface 1624, the brightness of the lighting lamp and other modules can be controlled and adjusted, and the dual-mode energy storage power supply 100 can also be remotely connected to WiFi, and the dual-mode energy storage power supply 100 can be remotely controlled and debugged in conjunction with the intelligent terminal.

[0081] In this embodiment, the grounding point of the dual-mode energy storage power supply 100 is used for household energy supply, which can effectively protect the safety of users and power supply equipment.
