Description

Technical Field

[0001] The present invention relates to the technical field of mobile power supplies, and particularly to a stackable outdoor energy storage power supply. Background Art

[0002] An energy storage battery is a device that can store electrical energy and release it when needed, and is widely used in outdoor activities, emergency power supplies, power supply for mobile devices and other fields. In outdoor usage scenarios, energy storage batteries need to have high capacity, high power output, portability, and the ability to adapt to various environmental conditions. With the popularization of outdoor activities, the demand for energy storage batteries is increasing day by day. Especially in environments far from the power grid, energy storage batteries have become an important tool to ensure power supply. To meet the power requirements of different users, modular-designed energy storage batteries have emerged, allowing users to flexibly adjust the battery capacity and power output according to actual usage.

[0003] In the prior art, stackable outdoor energy storage power supplies have become an important solution. For example, the stackable outdoor energy storage power supply with the publication number CN118054146A adopts a modular design. Users can adjust the number of battery modules according to their needs, thereby flexibly controlling the total capacity and output power of the power supply. This design realizes the scalability of capacity by stacking multiple battery modules and supports multiple charging methods to meet the power requirements in different scenarios. In addition, this patent also mentions that overcharge, over-discharge, short-circuit and other protection functions are realized through an intelligent battery management system to improve the safety and reliability of the power supply.

[0004] Although the prior art has solved the flexibility and capacity expansion problems of outdoor energy storage power supplies to a certain extent, there are still some significant drawbacks. First, when battery modules are stacked, they usually need to be closely attached to reduce the volume, but this design will lead to poor heat dissipation performance. Especially in the case of high power output or multi-module stacking, heat accumulation may cause a decline in battery performance or even pose a safety hazard. Second, the fire prevention and safety design of existing devices is relatively weak, lacking effective thermal runaway management and flame retardant measures. Once the battery overheats or short-circuits, it may cause a fire or explosion. In addition, as the stacking height increases, the stability of the device will also decrease, posing a risk of tipping or damage, further affecting the use safety. Summary of the Invention

It should be noted that: The words indicating directions such as up, down, left, and right in this text are only in terms of the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components in this text, for example: first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And as used in this application, terms such as connection and coupling, unless otherwise specified, all include direct and indirect connections.

[0029] Embodiment: A stackable outdoor energy storage power supply, as Figures 1-10As shown in the figure, it includes a frame 1, a power module 2 and a battery module 3. The battery module 3 and the power module 2 are placed inside the frame 1, and the power module 2 is located on top of the battery module 3. The power module 2 is used to control the input and output of power, and is provided with a variety of connectors and plugs to meet the user's usage requirements. It also includes universal wheels 11, positioning plates 12, docking connectors 31, a heat dissipation mechanism 4, a safety component 5 and a lifting mechanism 6. Four universal wheels 11 for moving the entire energy storage power supply are provided at the bottom of the frame 1. Two positioning plates 12 are connected to the rear side of the frame 1. A docking connector 31 is provided at the bottom of the battery module 3. The mutually stacked battery modules 3 can be connected to each other through the docking connector 31 for transmitting electric energy. The bottom battery module 3 is in limit fit with the positioning plate 12. A heat dissipation mechanism 4 for assisting heat dissipation is provided on the battery module 3. A safety component 5 for fire extinguishing is provided on top of the power module 2. Lifting components for vertically moving the battery module 3 are provided on the left and right sides of the frame 1.

[0030] As Figures 2-4 shown, the heat dissipation mechanism 4 includes a heat dissipation top plate 41, a ventilation bottom frame 42 and a fan 43. The heat dissipation top plate 41 is connected to the top of the battery module 3. The heat dissipation top plate 41 is composed of multiple spaced heat dissipation fins, which can increase the contact area with the air, thereby effectively dissipating heat. The ventilation bottom frame 42 is connected to the bottom of the battery module 3. A fan 43 is installed inside the ventilation bottom frame 42. Docking holes 44 are opened on both the heat dissipation top plate 41 and the ventilation bottom frame 42. The docking connector 31 passes through the docking holes 44; a number of ventilation holes 45 are provided on the ventilation bottom frame 42. The ventilation holes 45 are used to enhance air circulation. After the fan 43 is turned on, the air flow passes through the ventilation holes 45, accelerating air circulation. Moreover, for the stacked battery modules 3, the ventilation bottom frame 42 is in contact with the heat dissipation top plate 41, and ventilation holes 45 are also provided below the fan 43, accelerating the air circulation inside the heat dissipation top plate 41, thereby ensuring the working temperature of the battery module 3 and improving the usage safety.

[0031] As Figures 5-7As shown, the safety component 5 includes a cross tube 51, a telescopic tube 52, a nozzle 53, an elastic member 54, a thimble 55, a fixing bracket 56, a clamping plate 57, a first torsion spring 58, a ring handle 59 and a convex block 510. The cross tube 51 is arranged inside the power module 2. The end of the cross tube 51 is slidably connected with the telescopic tube 52. The end of the telescopic tube 52 is connected with the nozzle 53. The nozzle 53 is slidably connected to the four sides of the power module 2. The six nozzles provided on the nozzle 53 face downward. Since the power module 2 is located at the top, the extinguishing substance ejected can cover the entire area of the energy storage battery. The heat dissipation top plate 41 and the ventilation bottom frame 42 can not only isolate heat transfer and fire spread, but also provide a passage for the extinguishing substance. The extinguishing substance completely wraps the battery module 3. The bottom of the elastic member 54 is connected with the cross tube 51. There is a fixing bracket 56 on the power module 2. Three clamping plates 57 are rotatably connected to the fixing bracket 56. A first torsion spring 58 is sleeved on the fixing bracket 56. One end of the first torsion spring 58 is connected with the fixing bracket 56, and the other end is connected with the clamping plate 57. The clamping plate 57 is used to fix the compressed gas cylinder for releasing the extinguishing gas. Moreover, the top of the clamping plate 57 is set as an inclined surface. When the compressed gas cylinder is placed, the compressed gas cylinder contacts the inclined surface of the clamping plate 57, thereby pushing the clamping plate 57 outward. The clamping plate 57 rotates around the fixing bracket 56, twisting the first torsion spring 58. In the middle of the top of the cross tube 51, there is a thimble 55. The air outlet of the compressed gas cylinder is in pressing fit with the thimble 55. The other end of the elastic member 54 contacts the compressed gas cylinder. There is an electric power component inside the power module 2, which is used to control the movement of the thimble 55. The power component is a linear movement driving device, such as an electric push rod. When the power module 2 detects an accidental high temperature in the battery module 3, it controls the power component to move the thimble 55. After the thimble 55 is inserted into the compressed gas cylinder, the extinguishing substance stored in the compressed gas cylinder is released and enters the cross tube 51, and finally is ejected through the nozzle 53. A ring handle 59 is rotatably connected to the fixing bracket 56. The ring handle 59 is connected with a plurality of convex blocks 510. The convex blocks 510 are in pressing fit with the clamping plate 57. When the ring handle 59 is rotated, the convex blocks 510 rotate accordingly and press the clamping plate 57. When the clamping plate 57 rotates, it releases the compressed gas cylinder, and at the same time twists the first torsion spring 58, and the elastic member 54 ejects the compressed gas cylinder.

[0032] As Figure 8 and Figure 9As shown in the figure, the lifting mechanism 6 includes a motor 61, a lead screw 62, a guide rod 63, a sliding frame 64, a docking member 65, and a second torsion spring 66. The motor 61 is installed inside the frame 1. Both the upper and lower ends of the guide rod 63 are fixedly connected to the frame 1. The lead screw 62 is rotatably connected to the left and right sides of the frame 1. The lead screw 62 is parallel to the guide rod 63, and the bottom of the lead screw 62 is connected to the output shaft of the motor 61. One end of the sliding frame 64 is threadedly connected to the lead screw 62, and the other end is slidably connected to the guide rod 63. Moreover, the contact area of the end of the sliding frame 64 connected to the lead screw 62 is larger, so that when the lead screw 62 pushes the sliding frame 64, it is more stable. Moving grooves 32 are provided on both the left and right sides of the battery module 3. A docking member 65 is rotatably connected to the sliding frame 64. The docking member 65 can be inserted into the moving groove 32. A second torsion spring 66 is sleeved on the sliding frame 64. One end of the second torsion spring 66 is connected to the sliding frame 64, and the other end is connected to the docking member 65. The torsional force of the second torsion spring 66 makes the docking member 65 always closely adhere to the battery module 3. Thus, when the motor 61 drives the lead screw 62 to rotate and pushes the sliding frame 64 to move upward, the docking member 65 can smoothly insert into the moving groove 32 of the battery module 3 and lift the battery module 3. The bending setting of the docking member 65 provides a better stress point. When stacking the existing battery modules 3, it is necessary to remove the power module 2 at the top, and then completely lift the new battery module 3 and place it at the top, which increases the risk of splicing. However, when lifting from the bottom by the sliding frame 64, when the user adds a new battery module 3, the lifting height is lower and safer.

[0033] As Figure 10 shown, it further includes fixed blocks 7 and a scissor lift 71. Two fixed blocks 7 are slidably connected to the top surfaces of the left and right ends of the frame 1 and the left and right sides of the power module 2 respectively. A scissor lift 71 is rotatably connected between the fixed blocks 7 on the frame 1 and the fixed blocks 7 on the power module 2.

[0034] As Figure 1 and Figure 10 shown, it further includes solar panels 8. Two solar panels 8 are rotatably connected to the top of the power module 2. The solar panels 8 are used to charge the battery module 3, and a damping rotating shaft is provided at the rotating connection, which can maintain the inclination angle of the solar panels 8 to maximize the absorption of sunlight.

[0035] As Figure 2 shown, it further includes rollers 9. A plurality of rollers 9 are rotatably connected to the inner bottom of the frame 1. The bottom battery module 3 has a rolling friction with the rollers 9.

[0036] The user selects an appropriate number of battery modules 3 according to requirements. If a new battery module 3 needs to be added from the bottom, the motor 61 is turned on. The motor 61 drives the lead screw 62 to rotate, causing the sliding frame 64 to move upward. At the same time, the torque of the second torsion spring 66 causes the docking member 65 to closely adhere to the side of the battery module 3 and insert into the moving slot 32 of the battery module 3. The motor 61 continues to operate to lift the lower battery module 3. When the sliding frame 64 moves to the top of the guide rod 63, the motor 61 is turned off. When the user places the battery module 3 to be connected on the frame 1 and pushes the battery module 3, the rollers 9 on the frame 1 can reduce the friction between it and the battery module 3. When the battery module 3 contacts the positioning plate 12, the motor 61 rotates in reverse to control the slow descent of the upper battery module 3, so that the docking head 31 of the upper battery module 3 is docked with the lower battery module 3, thus completing the connection between the battery modules 3. Moreover, when the battery module 3 rises, the power module 2 at the top also moves upward. The power module 2 pulls the scissor lift 71 through the fixed block 7 to protect the part exceeding the frame 1. And the scissor lift 71 can support and guide the movement of the power module 2 to improve stability. Subsequently, the energy storage power supply is moved through the universal wheels 11 at the bottom of the frame 1; During use, the heat generated by the battery can be dissipated through the heat dissipation top plate 41. After the fan 43 is turned on synchronously, the air flow at the bottom of the battery module 3 is accelerated, thereby accelerating the heat loss, which is beneficial to maintaining the working temperature of the battery and ensuring the use safety. In special cases when emergency power is needed or it is detected that the battery power is insufficient, the solar panel 8 is rotated. The damping rotating shaft can fix the angle of the solar panel 8 so that it is perpendicular to the sunlight to fully absorb the sunlight and charge the battery module 3; The user inserts the compressed gas cylinder into the top of the power module 2, and the clamping plate 57 fixes it. Both the battery module 3 and the power module 2 are provided with a high-temperature detection function. When an accident occurs and the energy storage battery catches fire, the detection function is triggered, and the power assembly of the power module 2 controls the thimble 55 to move upward. The compressed gas cylinder releases gas towards the cross tube 51. The impact force of the gas causes the telescopic tube 52 to slide around and spray downward through the nozzle 53 to quickly cool the battery. At the same time, the fan 43 accelerates the air flow, so that the fire extinguishing substance surrounds the battery module 3 and quickly controls the fire, achieving effective fire extinguishing. When replacing the compressed gas cylinder, the fixing frame 56 is rotated through the annular handle 59, the convex block 510 presses the clamping plate 57, and the first torsion spring 58 is twisted. The clamping plate 57 releases the compressed gas cylinder, and the elastic member 54 ejects it. Just put a new compressed gas cylinder in. When removing the battery module 3, the upper battery module 3 needs to be lifted upward so that the docking head 31 is completely separated from the battery module 3.

[0037] The above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
