Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a square aluminum shell solid-state battery for energy storage with efficient thermal management. Background Art

[0002] A square aluminum shell solid-state battery is a solid-state battery using a square aluminum shell as the outer shell. It uses a solid electrolyte inside to replace the liquid electrolyte in traditional lithium batteries. Combining the mechanical strength and corrosion resistance of the aluminum shell, it forms a battery form with high safety and high energy density. This kind of battery performs well in terms of energy density, cycle life, and safety, and is widely used in various fields, and has also been widely used in the field of new energy vehicles.

[0003] The existing square aluminum shell solid-state battery has a relatively simple structure. Since the battery core is hermetically wrapped inside the aluminum shell, it only relies on the heat exchange between the outer shell and the outside world, and the heat dissipation efficiency is relatively low. Generally, it can meet the heat dissipation requirements of the battery. However, once abnormal temperature rise occurs, relying solely on the heat dissipation of the sealed aluminum shell cannot meet the heat dissipation requirements of the battery, and in severe cases, it is very likely to cause damage to the battery. Summary of the Invention

[0004] The purpose of the present invention is to provide a square aluminum shell solid-state battery for energy storage with efficient thermal management to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A square aluminum shell solid-state battery for energy storage with efficient thermal management, including a battery body. Heat dissipation channels are symmetrically arranged on the battery body, and the heat dissipation channels are used to dissipate heat from the battery body when the battery body is in an abnormally heated state; A channel closing component is installed in the heat dissipation channel. When the channel closing component is completely inserted into the heat dissipation channel, it closes the heat dissipation channel. When a part of the channel closing component protrudes above the heat dissipation channel, it realizes the communication between the inside of the battery body and the outside; A gas driving component is arranged on the battery body to drive the channel closing component through the gas driving component, driving the channel closing component to move up and down; A movable dust-proof mechanism is also installed on the battery body. The movable dust-proof mechanism cooperates with the channel closing component to play a dust-proof role, and the movable dust-proof mechanism is driven to move down by the channel closing component.

[0006] Preferably, the channel closing component is a channel closing sleeve, and the outer wall of the channel closing sleeve is closely attached to the inner wall of the heat dissipation channel.

[0007] Preferably, a ventilation channel is provided on the channel closing sleeve, and the inside of the battery body is communicated with the outside through the ventilation channel.

[0008] Preferably, the gas driving assembly includes a gas carrier strip and a gas closing plate, and the gas carrier strip is fixedly arranged on the battery body.

[0009] Preferably, a gas carrier cavity is arranged on the gas carrier strip, and the gas closing plate is inserted into the gas carrier cavity.

[0010] Preferably, the gas closing plate is connected to the channel closing sleeve to drive the channel closing sleeve to move up and down.

[0011] Preferably, the movable dust-proof mechanism includes a connecting linkage bar, a dust-proof net plate and a driving light strip. The connecting linkage bar is movably installed on the battery body, and when the channel closing sleeve moves upward, it drives the connecting linkage bar to move.

[0012] Preferably, the connecting linkage bar is movably connected to a driving light strip, and a bearing connecting rod is movably installed on the driving light strip.

[0013] Preferably, rod end bearing blocks are respectively fixedly arranged at both ends of the bearing connecting rod, and a matching driving insertion plate is fixedly arranged on the rod end bearing block.

[0014] Preferably, the driving light strip is connected to the dust-proof net plate through the matching driving insertion plate to drive the dust-proof net plate to move up and down.

[0015] Preferably, when the dust-proof net plate moves downward, the connecting linkage bar can limit the bearing connecting rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, and has the following advantages: 1. A heat dissipation channel is provided on the battery body, and a channel closing sleeve is installed in the heat dissipation channel. When the battery body is in a normal heat dissipation state, the heat dissipation channel is in a closed state under the action of the channel closing sleeve to ensure the overall sealing of the battery body. When the battery body is in an abnormal temperature rise state, the channel closing sleeve will no longer close the heat dissipation channel. At this time, the inside of the battery body can be communicated with the outside, further improving the heat dissipation efficiency inside the battery body and ensuring the safe use of the battery body.

[0017] 2. When the battery body is in an abnormal temperature rise state, the gas inside the gas carrier strip expands under the action of thermal expansion and contraction. As the gas expands, it will push the gas sealing plate to move. With the movement of the gas sealing plate, under the action of the upward push connecting rod, it will push the channel sealing sleeve to move upward, so that the air permeable channel on the channel sealing sleeve is exposed, thereby realizing the connection between the inside of the battery body and the outside world, and facilitating more effective heat dissipation of the battery body.

[0018] 3. In addition, as the channel sealing sleeve moves upward, it will drive the connecting linkage bar to move. With the movement of the connecting linkage bar, under the action of the downward pull connecting rod, it will drive the dust-proof net plate to move downward, so that the dust-proof net plate covers the air permeable channel. In this way, it can well prevent dust from the outside from entering the inside of the battery body. And as the connecting linkage bar moves, it will play a role in limiting the bearing connecting rod so that it cannot move. In this way, it can ensure that the dust-proof net plate can stably cover the air permeable channel and play a good dust-proof role. When the heat dissipation channel is in a closed state, the dust-proof net plate is between the two dust-proof guard plates. In this way, under the action of the dust-proof guard plates, it can prevent dust from accumulating on the dust-proof net plate, and the dust-proof net plate is convenient to install and disassemble, facilitating regular disassembly and cleaning.

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention provides a technical solution: As Figure 1 shown, a square aluminum shell solid-state battery for energy storage with high thermal management efficiency includes a battery body 1. Heat dissipation channels 11 are symmetrically arranged on the battery body 1. The heat dissipation channels 11 are used to dissipate heat from the battery body 1 when the battery body 1 is in an abnormal temperature rise state. A channel sealing assembly is installed in the heat dissipation channels 11. When the channel sealing assembly is completely inserted into the heat dissipation channels 11, it seals the heat dissipation channels 11. When a part of the channel sealing assembly protrudes above the heat dissipation channels 11, it realizes the communication between the inside of the battery body 1 and the outside. A gas driving assembly is arranged on the battery body 1. The gas driving assembly drives the channel sealing assembly to drive the channel sealing assembly to move up and down. An active dust-proof mechanism is also installed on the battery body 1. The active dust-proof mechanism cooperates with the channel sealing assembly to play a dust-proof role, and the active dust-proof mechanism is driven to move down by the channel sealing assembly.

[0032] As Figure 2 , Figure 6 and Figure 7As shown, moving grooves 12 are symmetrically formed on the battery body 1 at both ends of the heat dissipation channel 11, and a loading strip 13 is fixedly arranged on the battery body 1 beside the heat dissipation channel 11. Moving channels 14 are symmetrically formed on the loading strip 13, and a loading top plate 15 is fixedly arranged at the upper end of the loading strip 13. Insertion cavity holes 16 are symmetrically formed on the loading top plate 15, and two dust-proof guard plates 17 are fixedly arranged on the loading top plate 15.

[0033] As Figure 1 and Figure 3 shown, the channel closing assembly is a channel closing sleeve 3. The outer wall of the channel closing sleeve 3 is closely attached to the inner wall of the heat dissipation channel 11. A ventilation channel 31 is formed on the channel closing sleeve 3, and the interior of the battery body 1 is communicated with the outside through the ventilation channel 31. An upward convex top strip 32 is fixedly arranged on the channel closing sleeve 3. Support strips 33 are symmetrically and fixedly arranged at both ends of the upward convex top strip 32. An inclined surface driving frame 34 is fixedly arranged on the support strip 33, and the surface of the inclined surface driving frame 34 is smooth and free of burrs.

[0034] As Figure 1 , Figure 2 and Figure 3 shown, the gas driving assembly includes a gas strip 19 and a gas closing plate 2, and the gas strip 19 is fixedly arranged on the battery body 1.

[0035] As Figure 1 , Figure 2 , and Figure 4 shown, a gas cavity 191 is arranged on the gas strip 19. The gas cavity 191 is aligned with the moving channel 14 on the loading strip 13, and the inner wall of the gas cavity 191 is smooth and free of burrs. The gas closing plate 2 is inserted into the gas cavity 191, and the gas closing plate 2 is in close contact with the inner wall of the gas cavity 191. The gas closing plate 2 is connected to the channel closing sleeve 3 to drive the channel closing sleeve 3 to move up and down. In addition, a moving bearing rod 21 is fixedly arranged on the gas closing plate 2. The moving bearing rod 21 is inserted into the moving channel 14, and a connecting hanging plate 22 is fixedly arranged at the end of the moving bearing rod 21 away from the gas closing plate 2. The connecting hanging plate 22 is partially inserted into the moving groove 12, and a pushing connecting rod 23 is hinged on the connecting hanging plate 22. The upper end of the pushing connecting rod 23 is hinged to the upward convex top strip 32 on the channel closing sleeve 3.

[0036] As Figure 1 and Figure 5As shown, the movable dust-proof mechanism includes a connecting linkage bar 4, a dust-proof net plate 5, and a driving lightweight bar 6. The connecting linkage bar 4 is movably installed on the battery body 1. When the channel closing sleeve 3 moves upward, it drives the connecting linkage bar 4 to move. One end of the connecting linkage bar 4 is fixedly provided with an installation bearing rod 41. A connecting spring 42 is sleeved on the installation bearing rod 41, and the installation bearing rod 41 is inserted into the insertion cavity hole 16 on the load-bearing top plate 15. The two ends of the connecting spring 42 are respectively fixed on the connecting linkage bar 4 and the load-bearing top plate 15. A contact mating block 43 is fixedly provided on the connecting linkage bar 4 beside the installation bearing rod 41. The surface of the contact mating block 43 is smooth and free of burrs, and the contact mating block 43 is in contact with the inclined surface driving frame 34. The other end of the connecting linkage bar 4 is fixedly provided with a bearing protruding strip 44, and a limiting contact strip 45 is fixedly provided on the bearing protruding strip 44.

[0037] As Figure 8 shown, the connecting linkage bar 4 is movably connected to a driving lightweight bar 6. A bearing connecting rod 64 is movably installed on the driving lightweight bar 6. One end of the connecting linkage bar 4 near the bearing protruding strip 44 is hinged with a downward pulling connecting rod 46, and the upper end of the downward pulling connecting rod 46 is hinged with the driving lightweight bar 6.

[0038] As Figure 1 and Figure 10 shown, rod end bearing blocks 67 are respectively fixedly provided at both ends of the bearing connecting rod 64. A mating driving insertion plate 68 is fixedly provided on the rod end bearing blocks 67. The surface of the mating driving insertion plate 68 is smooth and free of burrs. Limiting mating channels 61 are symmetrically opened at both ends of the driving lightweight bar 6. Limiting bearing rods 181 are inserted into the limiting mating channels 61. The limiting top block 182 plays a role in limiting the driving lightweight bar 6. A bearing protruding strip 62 is also fixedly provided on the driving lightweight bar 6. A bearing channel 63 is opened on the bearing protruding strip 62. The bearing connecting rod 64 is inserted into the bearing channel 63. Operation bearing plates 65 are symmetrically fixedly provided on the bearing connecting rod 64. Elastic connecting strips 66 are fixedly provided on the operation bearing plates 65, and the other ends of the elastic connecting strips 66 are fixed on the bearing protruding strip 62.

[0039] As Figure 1 、 Figure 8 and Figure 9As shown, the driving of the light strip 6 drives the plug-in plate 68 to be connected with the dust-proof net plate 5 through cooperation, driving the dust-proof net plate 5 to move up and down. When the dust-proof net plate 5 moves downward, the connecting linkage bar 4 can limit the bearing connecting rod 64. The dust-proof net plate 5 is inserted between the two dust-proof guard plates 17, and the lower end of the dust-proof net plate 5 is inserted into the downward movement channel 171. Symmetrically fixed support ridges 51 are provided at the upper end of the dust-proof net plate 5, and cooperation bumps 52 are fixedly provided on the support ridges 51. A connecting channel 53 is provided on the cooperation bump 52. The inner wall of the connecting channel 53 is smooth and free of burrs, and a cooperation driving plug-in plate 68 is inserted into the connecting channel 53. The cooperation driving plug-in plate 68 is in contact with the inner wall of the connecting channel 53. In addition, when the connecting linkage bar 4 limits the bearing connecting rod 64, the limiting contact strip 45 on the connecting linkage bar 4 is in contact with the rod-end bearing block 67, so that the bearing connecting rod 64 can be restricted and cannot move.

[0040] When the battery body 1 is in a normal working state, the channel closing sleeve 3 is fully inserted into the heat dissipation channel 11. At this time, the air permeation channel 31 on the channel closing sleeve 3 is located in the heat dissipation channel 11. In this way, with the tight cooperation between the channel closing sleeve 3 and the heat dissipation channel 11, the heat dissipation channel 11 is in a closed state, ensuring the overall sealing of the battery body 1. When the battery body 1 is in an abnormal temperature rise state, the temperature of the battery body 1 is too high at this time. The high temperature acts on the gas in the gas carrier cavity 191, causing the gas to thermally expand. As the gas expands, it will push the gas closing plate 2 to move. As the gas closing plate 2 moves, it will drive the moving carrier rod 21 to move. In this way, as the moving carrier rod 21 moves, under the action of the upward pushing connecting rod 23, it will push the channel closing sleeve 3 to move upward. As the channel closing sleeve 3 moves upward, the air permeation channel 31 on the channel closing sleeve 3 will move out of the heat dissipation channel 11. In this way, under the action of the air permeation channel 31, the inside of the battery body 1 will be connected to the outside world, and the inside of the battery body 1 can be quickly cooled through the air permeation channel 31, further improving the heat dissipation efficiency of the battery body 1 and ensuring the safe use of the battery body 1. In addition, when the channel closing sleeve 3 moves upward, it will also drive the inclined plane drive frame 34 to move synchronously. As the inclined plane drive frame 34 moves upward, the inclined plane drive frame 34 will push the contact and cooperation block 43 to move away from the load-bearing top plate 15, and then can drive the connecting linkage bar 4 to move away from the load-bearing top plate 15. And as the connecting linkage bar 4 moves, under the action of the downward pulling connecting rod 46, it will drive the driving light bar 6 to move downward. Since the cooperation driving insertion plate 68 on the driving light bar 6 is inserted into the connecting channel 53 on the dust-proof net plate 5, as the driving light bar 6 moves downward, it will also drive the dust-proof net plate 5 to move downward. As the dust-proof net plate 5 moves downward, part of the dust-proof net plate 5 will move out between the two dust-proof guard plates 17, and at the same time, the dust-proof net plate 5 will cover the air permeation channel 31 on the channel closing sleeve 3. In this way, it can prevent external dust from entering the inside of the battery body 1 through the air permeation channel 31, which can play an effective dust-proof role and can also dissipate heat well. And as the connecting linkage bar 4 moves away from the load-bearing top plate 15, it will drive the limiting contact strip 45 on the connecting linkage bar 4 to move in the direction of the rod-end bearing block 67 close to it until finally the limiting contact strip 45 contacts the rod-end bearing block 67. In this way, the load-bearing connecting rod 64 can be limited from both ends, making it unable to move. Furthermore, the cooperation driving insertion plate 68 on the load-bearing connecting rod 64 is stably inserted into the connecting channel 53, ensuring the stability of the connection between the dust-proof net plate 5 and the driving light bar 6, and thus ensuring the stability of the dust-proof net plate 5 in the dust-proof work. And when the dust-proof net plate 5 does not move downward and is between the two dust-proof guard plates 17, the dust-proof net plate 5 is in a non-working state at this time, that is, the channel closing sleeve 3 does not move upward at this time.In this way, under the action of the two dust-proof guard plates 17, a good dust-proof effect can be achieved on the dust-proof net plate 5, avoiding the accumulation of dust on the dust-proof net plate 5 in the non-working state. When the temperature of the battery body 1 returns to normal, the temperature drops at this time, and the gas shrinks. This will cause the gas sealing plate 2 to move in the reverse direction, and at the same time, the channel sealing sleeve 3 will move downward to reset and be fully inserted into the heat dissipation channel 11 again to achieve the sealing of the heat dissipation channel 11. As the channel sealing sleeve 3 moves downward, the contact and cooperation block 43 will lose the restriction of the inclined surface driving frame 34. In this way, under the action of the connecting spring 42, the connecting linkage bar 4 will be driven to move in the reverse direction to reset. Furthermore, under the action of the downward pulling connecting rod 46, the driving light strip 6 will be driven to move upward, and then the dust-proof net plate 5 will be driven to be inserted between the two dust-proof guard plates 17 again to achieve reset, which can play a good protective role for the dust-proof net plate 5. It is very convenient. The battery body 1 can automatically open the heat dissipation channel 11 according to its own heat dissipation requirements, improving the heat dissipation efficiency. The structure is simple and the cost is low, which is very practical. In addition, when it is necessary to clean the dust on the surface of the dust-proof net plate 5, at this time, push one of the operation carrier plates 65 in the direction of the bearing rib 62 to drive the bearing connecting rod 64 to move, and then the two cooperating driving insertion plates 68 on the bearing connecting rod 64 can be driven to withdraw from the connecting channel 53. In this way, the separation between the dust-proof net plate 5 and the driving light strip 6 can be achieved, and the dust-proof net plate 5 can be quickly pulled out from between the dust-proof guard plates 17 for cleaning. After the cleaning is completed, at this time, insert the dust-proof net plate 5 back between the dust-proof guard plates 17 and reconnect it with the driving light strip 6 again. The operation is very simple, convenient and fast.
