[0043] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all structures.

[0044] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements.

[0045] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature has a lower horizontal height than the second feature.

[0046] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] As Figures 1-6 shown, this embodiment provides a battery-removable energy storage power supply, which has a housing 100, a battery compartment 200, a battery pack 300, and an inverter 520. Among them, the housing 100 includes a receiving cavity. The battery compartment 200 is fixed in the receiving cavity of the housing 100 and divides the receiving cavity into a first receiving area inside the battery compartment 200 and a second receiving area outside the battery compartment 200. The battery pack 300 is disposed in the first receiving area, while the inverter 520 is installed in the second receiving area. The inverter 520 is electrically connected to the battery pack 300 to control the charging and discharging functions of the battery pack 300.

[0048] Furthermore, as Figures 1-6 shown, the battery pack 300 is detachably installed in the battery compartment 200. An opening 10 for the battery pack 300 to enter and exit is provided on one side of the energy storage power supply. At least one of the housing 100 and the battery compartment 200 is provided with a limiting member, and the limiting member can open or close the opening 10 to selectively limit the battery pack 300 in the battery compartment 200. And, the energy storage power supply further includes a fan 540. The fan 540 is installed in the second receiving area. One end of the fan 540 faces the opening 10, and the other end faces the inverter 520.

[0049] Specifically, in the battery-removable energy storage power supply provided in this embodiment, an independent battery compartment 200 is provided in the housing 100. The battery compartment 200 divides the receiving cavity into a first receiving area and a second receiving area. The inverter 520, the battery pack 300 is detachably installed in the first receiving area, and both the inverter 520 and the fan 540 are installed in the second receiving area. By setting an independent compartment structure, on the one hand, the structure inside the energy storage power supply is divided in a modular form, improving the structural strength and avoiding the risk of collision between the battery pack 300 and the inverter 520 during the replacement process. On the other hand, the battery pack 300 is fixed in the battery compartment 200 by the limiting member. When disassembling and assembling, only the state of the limiting member needs to be changed to fix the battery pack 300 or open the opening 10 for battery replacement, without an additional locking structure to fix the battery pack 300. The disassembly and assembly structure is simple, and the installation structure is stable and reliable. Moreover, the opening 10 of the energy storage power supply also has a ventilation function. The fan 540 can drive the air flowing in from the outside to flow through the inverter 520 at a higher flow rate to accelerate the heat dissipation of the inverter 520 and improve the heat dissipation efficiency.

[0050] For example, Figures 1-3 As shown, the outer shell 100 includes a front shell 110 and a rear shell 120. Both the front shell 110 and the rear shell 120 are set to a C-shaped structure. Both the upper and lower ends are provided with protrusions. The two protrusions at the upper end are connected and fixed by screws to form the top of the outer shell 100. The two protrusions at the lower end are also connected and fixed by screws to form the bottom of the outer shell 100. The opposite ends of the outer shell 100, specifically the left and right ends of the outer shell 100, are provided with openings 10 to form a heat dissipation duct in the outer shell 100. At least one end of the battery compartment is provided with an avoidance opening 20 for the battery pack 300 to pass through. The avoidance opening 20 for replacing the battery pack 300 is arranged in the same direction as an opening 10. The battery pack 300 and the inverter 520 are both located in the heat dissipation duct, and the heat is taken away by the airflow flowing through the heat dissipation duct to achieve cooling.

[0051] For example, Figure 1 and Figure 2 As shown, the energy storage power supply further includes a ventilation sheet 130, which is detachably connected to the opening 10 to selectively open or close the opening 10. The ventilation sheet 130 is provided with a ventilation grid window structure to form a vent 30. When the ventilation sheet 130 is installed on the opening 10, air is also allowed to pass through the opening 10 without affecting heat dissipation and ventilation. In this embodiment, ventilation sheets 130 are installed on both openings 10, and the ventilation sheets 130 are installed at the position of the opening 10 by multiple screws. In other embodiments, the ventilation sheets 130 can also be detachably connected to the opening 10 by a structure such as a buckle.

[0052] For example, please refer to Figure 1 and Figure 2 A handle 140 is provided on the outer shell 100, and the upper protrusions of the front shell 110 and the rear shell 120 are provided with installation grooves. When the front shell 110 and the rear shell 120 are connected and fixed, the two installation grooves are enclosed to form a hinge hole, and the handle 140 is rotatably installed in the hinge hole. The handle 140 can be used by the user to conveniently lift the energy storage power supply.

[0053] For example, Figures 2-6 As shown, the battery compartment 200 includes a supporting base plate 210 and a fixing bracket 220, both of which are made of sheet metal materials with high structural strength. The fixing bracket 220 is configured as a "冂"-shaped structure, and the supporting base plate 210 is fixed to the bottom of the fixing bracket 220 by welding or screws. The bottom of the outer shell 100 supports the supporting base plate 210, and the bottom of the fixing bracket 220 is connected to the supporting base plate 210. At least one of the supporting base plate 210 and the fixing bracket 220 is connected to the outer shell 100, and one end of the fixing bracket 220 is configured as an open structure to form an avoidance opening 20.

[0054] Specifically,Figure 3 and Figure 4 As shown, multiple support ribs 101 are provided on the lower protrusions of the front shell 110 and the rear shell 120, and the multiple support ribs 101 jointly support the support bottom plate 210. Multiple positioning columns 221 are provided on the two side walls of the fixed bracket 220, and multiple positioning piles 102 are correspondingly provided on the inner side walls of the front shell 110 and the rear shell 120, and positioning holes are provided on the positioning piles 102. Before the front shell 110 and the rear shell 120 are assembled, the assembled battery compartment 200 is first placed between the front shell 110 and the rear shell 120, so that the positioning columns 221 on both sides are respectively inserted into the corresponding positioning holes. At this time, the front shell 110 and the rear shell 120 are also in the docking position, and the staff locks the front shell 110 and the rear shell 120 with screws, that is, the connection and installation between the front shell 110 and the rear shell 120, and between the outer shell 100 and the battery compartment 200 are completed. It can be seen that the arrangement of the positioning column 221 and the positioning post 102 can simultaneously assist in the rapid positioning and docking between the front shell 110 and the rear shell 120, and between the outer shell 100 and the battery compartment 200, which is conducive to improving production efficiency. Furthermore, since the battery compartment 200 is a structure independently arranged in the outer shell 100, when corresponding to battery packs 300 of different sizes, the front shell 110 and the rear shell 120 can be disassembled to conveniently replace the battery compartment 200 of different sizes, greatly improving versatility.

[0055] Exemplarily, a connection structure such as a threaded seat may be provided on the front shell 110 and / or the rear shell 120 , and the battery compartment 200 may be fixed to the front shell 110 and / or the rear shell 120 by screws to further improve the structural stability.

[0056] For example, Figure 1 As shown, the avoidance opening 20 is arranged in the same direction as an opening 10. On the one hand, when the battery pack 300 needs to be replaced, the avoidance opening 20 can be exposed by simply removing the ventilation sheet 130, so that the user can take out or put in the battery pack 300 from the opening 10; on the other hand, the cold air entering through the opening 10 can be directly poured into the battery compartment 200 from the avoidance opening 20, so as to efficiently cool the battery pack 300 in the battery compartment 200. The end of the battery compartment 200 facing away from the opening 10 can be set as a hollow structure so as to connect to another opening 10 for the air flowing through the battery pack 300 to flow out, accelerate the heat dissipation of the battery pack 300, and improve the cooling effect of the battery pack 300.

[0057] For example, Figure 1 , Figure 2 , Figures 4-6As shown in the figure, the limiting member includes a limiting plate 400. The ventilation fin 130 is located outside the limiting plate 400. The first end of the limiting plate 400 is movably arranged on one side of the avoidance opening 20, and the second end of the limiting plate 400 is detachably connected to the other side of the avoidance opening 20. When disassembling and assembling the battery pack 300, the second end of the limiting plate 400 is removed from the avoidance opening 20, and the first end of the limiting plate 400 moves relative to the avoidance opening 20, then the avoidance opening 20 can be opened. When the second end of the limiting plate 400 is connected to the other side of the avoidance opening 20, the limiting plate 400 presses the battery pack 300 against the other end in the battery compartment 200 to fix the battery pack 300 in the battery compartment 200.

[0058] Of course, in some embodiments, the first end and the second end of the limiting plate 400 can also be respectively detachably connected to both sides of the avoidance opening 20. When disassembling and assembling the battery pack 300, the whole limiting plate 400 can be disassembled.

[0059] Exemplarily, the limiting plate 400 can be installed on the battery compartment 200 or on the outer housing 100. In this embodiment, as Figures 4-6 shown, the first end of the limiting plate 400 is slidably connected to the battery compartment 200, and the second end of the limiting plate 400 is detachably connected to the battery compartment 200. Specifically, a sliding plate 230 is fixedly installed at one end of the battery compartment 200 close to the avoidance opening 20. A sliding groove 231 is provided on the sliding plate 230. The first end of the limiting plate 400 is slidably arranged in the sliding groove 231, and the limiting plate 400 can be completely separated from the sliding groove 231 to fully open the avoidance opening 20. The second end of the limiting plate 400 is provided with a limiting groove 401 and a mounting hole 402. A positioning pin 222 and a threaded hole 223 are provided on the battery compartment 200. The positioning pin 222 passes through the limiting groove 401, and the positioning pin 222 supports the top wall of the limiting groove 401. The second end of the limiting plate 400 is fixed to the battery compartment 200 by a fastening screw 600 passing through the mounting hole 402 and threadedly connected to the threaded hole 223. Relying on the cooperation between the positioning pin 222 and the limiting groove 401 to limit the height position of the limiting plate 400 can reduce the amount of the fastening screw 600, reduce the cost and simplify the process of replacing the battery pack 300.

[0060] Furthermore, as Figure 5 and Figure 6 shown, the limiting groove 401 is set as a square groove structure, and its length direction is the same as the sliding direction of the limiting plate 400, providing a guiding function for the sliding disassembly and assembly of the limiting plate 400.

[0061] Exemplarily, the limiting plate 400 is set as a long strip plate structure and is made of sheet metal.

[0062] In some embodiments, the limiting member may also include a ventilation fin 130. The inner sidewall of the ventilation fin 130 can directly abut against the sidewall of the battery pack 300. The ventilation fin 130 and the limiting plate 400 can cooperate to limit the battery pack 300 together, so as to improve the installation reliability.

[0063] In other embodiments, the limiting member may only include the ventilation fin 130. The battery pack 300 can be limited independently by directly abutting the inner sidewall of the ventilation fin 130 against the sidewall of the battery pack 300, without setting an additional limiting structure, further simplifying the structure and reducing the cost.

[0064] Exemplarily, as Figure 4 and Figure 6 shown, a guiding structure is provided on the supporting bottom plate 210. The extending direction of the guiding structure is adapted to the disassembly and assembly direction of the battery pack 300. The battery pack 300 can slide relative to the supporting bottom plate 210 along the guiding structure. Specifically, the guiding structure includes a plurality of strip-shaped guiding convex protrusions 211. The plurality of guiding convex protrusions 211 are arranged side by side in two columns. Two guiding grooves are correspondingly arranged at the bottom of the battery pack 300. The guiding grooves are slidably matched with the guiding convex protrusions 211 to provide guiding support for the sliding of the battery pack 300. Of course, the guiding structure can also adopt other sliding matching structures such as guide rails and guide grooves in the prior art.

[0065] Exemplarily, as Figure 6 shown, a handle 301 is provided at one end of the battery pack 300 close to the avoidance opening 20, so that a user can drag the battery pack 300 to slide relative to the battery compartment 200.

[0066] Exemplarily, please refer to Figure 2 、 Figures 4-6 . There are two air blowers 540. The two air blowers 540 are arranged at intervals along the length direction of the heat dissipation air duct. The two air blowers 540 are respectively installed at both ends of the circuit board of the inverter 520 and face the same direction, which can further accelerate the heat dissipation of the inverter 520.

[0067] Exemplarily, please refer to Figures 1-6 . The energy storage power supply further includes a battery protection board 510 and a main board 530. Among them, the battery protection board 510 is fixed on the outer sidewall of the battery compartment 200 and is electrically connected to the battery pack 300; the inverter 520 is fixed on the outer top wall of the battery compartment 200. The battery pack 300 is electrically connected to the battery protection board 510 and is connected to the inverter 520; the main board 530 is fixed on the inner sidewall of the outer housing 100 and is electrically connected to the inverter 520.

[0068] Specifically, the battery protection board 510 is attached to one side of the fixing bracket 220 near the rear case 120 by screws. The battery protection board 510 is provided with a charge and discharge switch, which can detect information such as the current, voltage, and temperature of the battery pack 300. When abnormal conditions such as overcurrent (short circuit), low voltage (undervoltage), and high temperature are detected, the charge and discharge switch disconnects to prevent the battery pack 300 from continuing to charge or discharge, thus playing a continuous status monitoring and power-off protection function and improving the working reliability. The inverter 520 is attached to the top of the fixing bracket 220 by screws and is used to convert the direct current output by the battery pack 300 into alternating current to adapt to household appliances. The main board 530 is attached to the inner wall of the front case 110 by screws. The front case 110 is provided with a functional area, and a plurality of avoidance holes are provided on the functional area for a plurality of charging ports and a display screen on the main board 530 to pass through. The role of the main board 530 in the energy storage power supply is to coordinate the overall operation, and the objects of coordination include user interface display, power switching logic, data communication, safety protection, etc.

[0069] In this embodiment, by installing the battery protection board 510 and the inverter 520 through the fixing bracket 220 of the battery compartment 200, it can play the role of reducing the number of parts and lowering the cost. Since the battery protection board 510, the inverter 520, and the main board 530 are respectively distributed on the front and rear sides and the top of the battery compartment 200, the space between the outer casing 100 and the battery compartment 200 is fully utilized, the overall structure is more compact, the layout and weight distribution are more reasonable, and the battery protection board 510, the inverter 520, and the main board 530 are respectively located in different positions in the air duct, which can avoid heat cross-flow and mutual interference and improve the heat dissipation effect.

[0070] Exemplarily, please refer to Figure 6 , the battery pack 300 is provided with an integrated interface 302, and the integrated interface 302 is electrically connected to the inverter 520 or the battery protection board 510 through a wire harness. Specifically, in this embodiment, the battery protection board 510 is separately provided from the battery pack 300. The battery pack 300 is electrically connected to the battery protection board 510 through a wire harness connected to the integrated interface 302 and then connected to the inverter 520, that is, the battery pack 300 and the inverter 520 are indirectly connected through an external battery protection board 510. In some embodiments, a BMS unit can be integrated in the battery pack 300, so the battery pack 300 can be directly connected to the inverter 520 through a wire harness connected to the integrated interface 302.

[0071] Preferably, please refer to Figure 6 , the integrated interface 302 is arranged on one side of the battery pack 300 close to the avoidance port 20 to facilitate the user to plug and unplug the wire harness when disassembling and assembling the battery pack 300.
