Description

Technical Field

[0001] This utility model relates to the field of energy storage device technology, specifically to a high-performance energy storage device with adaptive regulation. Background Technology

[0002] In today's global context of actively promoting energy transition and rapid development of electronic technology, energy storage devices play a crucial role. They enable the effective storage and on-demand release of energy, such as electricity, and are indispensable for addressing the intermittent power generation issues of renewable energy sources (such as solar and wind power), ensuring the stable operation of smart grids, providing reliable power for electric vehicles, and supporting the uninterrupted operation of various electronic devices. Many common types of energy storage devices exist, such as lithium-ion batteries and supercapacitors, each with its own advantages and widely adopted in various application scenarios. Furthermore, with continuous technological advancements, the market's performance requirements for energy storage devices are increasing, with expectations for continued development towards higher energy density, higher power density, and longer cycle life.

[0003] However, while existing adaptive high-performance energy storage devices improve energy conversion efficiency, they also generate a significant amount of heat. If this heat cannot be dissipated in a timely and effective manner, it will bring many negative effects to the energy storage device. Excessively high temperatures can cause changes in the structure of electrode materials, accelerating their aging process, leading to a gradual decrease in battery capacity and a decline in charge-discharge performance. At the same time, high temperatures may also cause electrolyte decomposition, producing gas, which not only affects the stability of the internal chemical environment of the energy storage device but may also increase internal pressure. In severe cases, it may even trigger thermal runaway, posing a significant safety hazard and threatening the safety of surrounding equipment and personnel. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A high-performance energy storage device with adaptive regulation, such as Figures 1-5 As shown, it includes an energy storage box 1, and a radiator 2 is fixedly installed inside the energy storage box 1;

[0027] It also includes an active component 3 for dissipating the heat retained inside the energy storage box 1;

[0028] The swing component 4 is used to change the air circulation effect inside the energy storage box 1;

[0029] First, the active component 3 includes: a fixed block 31, which is fixedly installed inside the energy storage box 1. A fixed plate 32 is fixedly installed inside the fixed block 31. A thermal expansion airbag 33 is placed inside the fixed block 31. A movable rod 34 is attached to the right side of the thermal expansion airbag 33. The movable rod 34 passes through the fixed plate 32. A connecting plate 35 is fixedly installed on the surface of the movable rod 34. A push rod 36 is hinged to the surface of the connecting plate 35. A toothed plate 37 is hinged to the surface of the push rod 36. The toothed plate 37 is slidably connected to the inner wall of the energy storage box 1. A heat dissipation strip 38 is rotatably connected inside the energy storage box 1. A gear 39 is fixedly installed on the outside of the heat dissipation strip 38. The gear 39 is rotatably connected to the inside of the energy storage box 1. The gear 39 meshes with the surface of the toothed plate 37. The gear 39 and the heat dissipation strip 38 can be driven to swing by the sliding of the toothed plate 37 on the surface of the gear 39.

[0030] Secondly, a fixing spring 310 is fixedly installed on the surface of the movable rod 34. The fixing spring 310 is fixedly installed on the outer wall of the fixing plate 32. The fixing spring 310 on the surface of the movable rod 34 can achieve the effect of resetting after the movable rod 34 has moved.

[0031] Furthermore, a movable block 311 is slidably connected inside the fixed block 31. The movable block 311 is attached to the left side of the thermal expansion airbag 33. The movable block 311 passes through the top of the fixed block 31. A connecting rod 312 is fixedly installed on the top of the movable block 311. A push plate 313 is fixedly installed on the top of the connecting rod 312. A heat dissipation plate 314 is fixedly installed on the push plate 313. A short plate 315 is fixedly installed on the inner side of the heat dissipation plate 314. The short plate 315 is slidably connected inside the energy storage box 1. One end of a movable spring 316 is fixedly installed on the outer side of the movable block 311. It can be pushed by the push plate 313 through the heat dissipation plate 314 to open the heat dissipation slot on the left side of the energy storage box 1.

[0032] In this embodiment, the movable component 3, when the heat inside the energy storage box 1 increases, causes the thermal expansion airbag 33 to expand. When the thermal expansion airbag 33 expands, it will push against the movable rod 34, the connecting plate 35, and the push rod 36 hinged to the surface, sliding to the right. When the push rod 36 slides to the right, it will drive the toothed plate 37 to slide upward on the inner wall of the energy storage box 1. When the toothed plate 37 slides upward, it will drive the gear 39 meshing on the surface to rotate. When the gear 39 rotates, it will drive the heat dissipation strip 38 to swing upward, thereby increasing the area of ​​the heat dissipation opening of the energy storage box 1, preventing excessive heat accumulation inside the energy storage box 1, improving overall performance, extending service life, and enhancing safety.

[0033] Example 2

[0034] like Figure 6 As shown, the swing assembly 4 includes: a connecting block 41, which is fixedly installed on the top of the fixed block 31; the other end of the movable spring 316 is fixedly installed on the outside of the connecting block 41; a push plate 313 is slidably connected to the inside of the connecting block 41; a rotating shaft 42 is rotatably connected to the right side of the connecting block 41; a sliding rod 43 is slidably connected to the surface of the rotating shaft 42; and the sliding rod 43 is fixedly installed on the top of the connecting plate 35.

[0035] Furthermore, a rotating rod 44 is fixedly installed on the outer side of the rotating shaft 42, and a gear 45 is fixedly installed on the surface of the rotating rod 44. A rotating shaft 46 is rotatably connected to the top of the connecting block 41. A swing plate 47 is fixedly installed on the surface of the rotating shaft 46, and a large gear 48 is fixedly installed on the surface of the rotating shaft 46. The large gear 48 meshes with the bottom of the gear 45. A spiral spring 49 is fixedly installed on the surface of the rotating shaft 46 and is fixedly installed on the top of the connecting block 41. The spiral spring 49 on the surface of the rotating shaft 46 can achieve the effect of resetting after the rotating shaft 42 has finished rotating.

[0036] Finally, a groove 3100 is provided on the surface of the fixing block 31, which can improve the connection effect between the connecting rod 312 and the push plate 313. A sliding groove 3101 is provided on the top of the fixing block 31, which can drive the sliding rod 43 to slide on the top of the fixing block 31. A reciprocating sliding groove 420 is provided on the surface of the rotating shaft 42, which can drive the rotating shaft 42 to reciprocate when the sliding rod 43 slides.

[0037] In this embodiment, by setting the swing component 4, when the connecting plate 35 slides inside the fixed block 31, it will also drive the top sliding rod 43 to slide. When the sliding rod 43 slides, it will slide on the surface of the rotating shaft 42. When the sliding rod 43 slides, it will drive the rotating shaft 42 to reciprocate. When the rotating shaft 42 rotates, it will drive the gear disk 45 to rotate through the rotating rod 44. When the gear disk 45 rotates, it will drive the bottom meshing large gear 48 and the rotating shaft 46 to reciprocate left and right. When the rotating shaft 46 reciprocates, it will drive the swing plate 47 to swing left and right. When the swing plate 47 swings left and right, it will change the air circulation effect, prevent the heat from not being dissipated in time and effectively due to poor air circulation, accelerate the heat dissipation speed, enhance the overall heat dissipation efficiency, better maintain the suitable temperature inside the energy storage device, ensure that the energy storage device can operate stably in a high-performance state, and improve its working reliability and service life.

[0038] In use, the adaptive and high-performance energy storage device of this invention typically dissipates heat through a fixed internal radiator 2. Firstly, according to the ideal gas law PV = nRT (where P represents gas pressure, V represents gas volume, n represents the amount of gas, R is the universal gas constant, and T is the thermodynamic temperature), in the context of the airbag, the amount of gas n inside remains constant because the airbag is sealed and the gas does not leak out, thus there is no increase or decrease in substance. However, when external factors cause the temperature T to rise, such as an increase in ambient temperature or heating by a heat source, to ensure the equation still holds, since n and R remain constant, the product of pressure P and volume V needs to be changed accordingly. Furthermore, in reality, the airbag is exposed to external atmospheric pressure, and the internal air pressure tends to maintain equilibrium with the external atmospheric pressure. When the temperature rises, causing the internal gas pressure to tend to increase (according to the ideal gas law, the pressure will increase when the temperature rises while the volume remains constant), the airbag can only increase its own volume V by expanding, so that the internal pressure P can gradually decrease as the volume increases, until it is equal to the external atmospheric pressure again, and a new state of internal and external pressure equilibrium is achieved. Therefore, under rising temperatures, based on the ideal gas law and the requirement of internal and external pressure balance, the airbag will expand. When the energy storage box 1 is used for a long time, the heat flow accumulated inside it will increase, resulting in increased internal heat. When the internal heat of the energy storage box 1 increases, it will cause the thermal expansion airbag 33 to expand. (Specifically, the internal air pressure always remains in balance with the external atmospheric pressure. When the temperature rises, the temperature of the gas inside the airbag rises. According to the ideal gas law PV = nRT, if the airbag is sealed (n remains constant), the increase in temperature T will lead to an increase in pressure P. At this time, the airbag will expand until the internal pressure is in balance with the external atmospheric pressure, and the volume will increase.) When the thermal expansion airbag 33 expands, it will resist the movable rod 34 and slide to the right. Assuming the contact area between the airbag and the movable rod 34 is S, according to the definition of pressure F = PS, the gas pressure P inside the airbag is always equal to the external atmospheric pressure (ignoring the elastic force of the airbag itself, etc.). The force exerted by the airbag on the movable rod 34 is atmospheric pressure. For example, given the external atmospheric pressure and a contact area S = 0.1 m², the force F = 101325 × 0.1 = 10132.5 N. Force analysis of the movable rod 34: The movable rod 34 is subjected to the thrust F from the airbag, its own frictional force f (assuming it exists), and other resistance forces (such as the spring force). For the movable rod 34 to move, these resistance forces must be satisfied. If the coefficient of friction μ, mass m, and other resistance forces of the movable rod 34 are known, it can be determined whether the thrust of the airbag can move the movable rod 34. For example, if the mass m = 10 kg and the coefficient of friction μ = 0.2, then the frictional force f = μmg = 0.2 × 10 × 9.8 = 19.6 N. If other resistance forces are present, and the airbag thrust F = 10132.5 N, then obviously the movable rod 34 will be moved.

[0039] When the movable rod 34 slides to the right, it will cause the connecting plate 35 and the push rod 36 hinged to the surface to slide to the right. When the push rod 36 slides to the right, it will cause the toothed plate 37 to slide upward on the inner wall of the energy storage box 1. When the toothed plate 37 slides upward, it will cause the meshing gear 39 to rotate. When the gear 39 rotates, it will cause the heat sink 38 to swing upward. When the thermal expansion airbag 33 expands, it will also resist the movable block 311 and slide to the left inside the fixed block 31. When the movable block 311 slides to the left, it will cause the connecting rod 312 to slide to the left. When the connecting rod 312 slides to the left, it will drive the push plate 313 and the heat dissipation plate 314 to slide to the left, thereby increasing the area of ​​the heat dissipation opening of the energy storage box 1, preventing excessive heat accumulation inside the energy storage box 1, which could lead to excessive temperature and cause accelerated aging of electrode materials, decomposition of electrolyte, thermal runaway, etc., affecting the cycle life of the energy storage device, enhancing the heat dissipation effect, enabling the energy storage device to better adapt to long-term use or high-load operation, ensuring its stable and reliable operation under complex and changing conditions, improving overall performance, extending service life, and enhancing safety.

[0040] When the connecting plate 35 slides inside the fixed block 31, it also drives the top sliding rod 43 to slide. When the sliding rod 43 slides, it slides on the surface of the rotating shaft 42. Since the rotating shaft 42 has a reciprocating groove 420 on its surface, the sliding rod 43 drives the rotating shaft 42 to reciprocate. When the rotating shaft 42 rotates, it drives the gear disk 45 to rotate through the rotating rod 44. When the gear disk 45 rotates, it drives the large gear 48 meshing at the bottom to rotate. When the large gear 48 rotates, it drives the rotating shaft 46 to reciprocate left and right. When the rotating shaft 46 reciprocates, it drives the swing plate 47 to swing left and right. When the swing plate 47 swings back and forth, it changes the air circulation effect, preventing heat from not being dissipated in time and effectively due to poor air circulation. This prevents heat from accumulating continuously inside the energy storage box 1, affecting the normal heat dissipation of the energy storage device 1, and causing serious problems such as thermal runaway and other issues caused by poor heat dissipation. It optimizes the heat dissipation environment, promotes the exchange of air inside and outside the energy storage box, accelerates the heat dissipation rate, enhances the overall heat dissipation efficiency, better maintains the appropriate temperature inside the energy storage device, ensures that the energy storage device can operate stably under high performance, and improves its operational reliability and service life.
