Battery rack assembly of a portable sodium-ion battery power supply and its assembly method

Abstract

The present invention discloses a sodium-ion battery assembly for energy storage and its usage method, including a protective housing. An explosion-proof cavity is provided at the lower end of the protective housing, and ventilation holes are formed on the inner wall of the explosion-proof cavity. By dividing the entire protective housing into two chambers and cooperating with an isolation unit, the sodium-ion battery pack is separated and placed in normal and abnormal states. With the setting of the battery protection unit, it is ensured that when the sodium-ion battery pack body expands due to heat, it can prevent the expansion speed from being too fast in the first place, reducing the conditions for the sodium-ion battery pack body to burn. The falling flame retardant unit is inserted into the sodium-ion battery pack body in normal operation. Once the sodium-ion battery pack body expands and deforms, the falling flame retardant unit disengages from it, and the sodium-ion battery pack body falls under the action of gravity to the explosion-proof cavity for isolation, being isolated from adjacent battery packs that have not experienced abnormalities to prevent collateral damage.

Description

Technical Field

[0001] The present invention belongs to the technical field of sodium-ion battery power supplies, and particularly relates to a battery rack assembly for a portable sodium-ion battery power supply and an assembly method thereof. Background Art

[0002] Sodium-ion batteries have a relatively high energy density and can provide a longer cruising range or usage time, which makes them very suitable as power sources for portable electronic devices. Secondly, sodium-ion batteries have a better cycle life and can withstand more charge and discharge cycles while maintaining relatively stable performance, which is particularly important for portable devices that require long-term stable power supply. In addition, sodium-ion batteries also have high safety and are not prone to safety problems such as thermal runaway or explosion, which makes them a reliable power source option.

[0003] In the prior art, a portable battery pack with a publication number of CN218586167U includes a pack body and a wiring port. Two reinforcing ribs are fixedly installed on both side surfaces of the pack body. One end of the two reinforcing ribs away from the pack body is fixedly installed with a guide rail. A cover plate is slidably connected between the two guide rails. A sealing plate mechanism for restricting the movement of the cover plate is arranged on the surface of one of the guide rails. A wiring port for external wiring cables is arranged on the surface of the cover plate. A handle is fixedly installed on the side surface of the cover plate. A reinforcing strip is integrally formed on the surface of the pack body. A battery body is arranged on the inner bottom surface of the pack body. Two support arms are arranged on both inner walls of the pack body. A connecting plate B is assembled at the upper end of the support arm. A filter screen is fixedly installed at one end of the connecting plate B away from the support arm. By enabling the filter screen to be detached from the inside of the pack body, dust accumulation on the surface of the filter screen can be avoided, which affects heat dissipation, and further improves its heat dissipation performance.

[0004] In order to solve the problem that dust is likely to accumulate on the surface of the battery pack during long-term use, affecting the heat dissipation effect, the prior art is to adopt the method of removing and cleaning the filter screen that blocks dust.

[0005] However, during actual use, the battery pack is directly placed in the pack body for storage, and the assembly between monomers cannot be achieved. When maintaining the battery pack, only the entire battery pack can be disassembled. The connection method is single, and there are limitations in the management of the number and arrangement of batteries.

[0006] Therefore, we propose a battery rack assembly for a portable sodium-ion battery power supply and an assembly method thereof to solve the problems of single existing battery connection method and large limitations in the management system, and can perform portable fixing assembly and separation of single batteries to strengthen the protection of the battery assembly.

A frame connection mechanism 2 is installed inside the battery installation housing 1. The frame connection mechanism 2 includes an inner frame side plate 21, a positioning truss 22, and a diversion plate 23. A battery pack protection and isolation mechanism 3 is arranged inside the frame connection mechanism 2. The battery pack protection and isolation mechanism 3 includes a monomer assembly unit 31, a sodium-ion battery pack 32, and a separation unit 33. A stable anti-sway component is arranged inside the top cover 12; by adopting the frame connection mechanism 2 as a whole to realize the frame support of the sodium-ion battery power supply, ensuring sufficient structural strength of the battery pack, and using the mutual cooperation of the inner frame side plate 21 and the diversion plate 23 to realize the gas circulation and flow between the battery packs assembled inside the frame, maintaining the stable operation of the sodium-ion battery power supply. By designing multiple slots inside the frame for fixing and separating sodium-ion battery monomers, ensuring electrical isolation between the batteries, facilitating the disassembly and installation of the single batteries, and installing hollow corrugated separation plates 331 with a wavy shape on both sides of the single battery pack after assembly, facilitating the flow of air in the gaps. At the same time, cooperating with the additional buffer component 333 to strengthen the side buffer protection of the single battery, avoiding deformation reaction after being impacted externally, realizing the isolated assembly of the battery pack monomers, and being able to realize separate isolated placement and disassembly, greatly reducing the limitations of the number and arrangement management of the batteries, and further improving the convenience of the frame assembly of the sodium-ion battery power supply.

[0049] Example 2, referring to the attached Figure 1-19, on the basis of Embodiment 1, this embodiment adds a stable anti - sway component: The stable anti - sway component includes a rotating rod rotatably installed on the inner surface of the top cover 12. A connecting rotating tooth is fixedly installed on the outer surface of the lower end of the rotating rod. Meshing tooth rods are respectively meshed and rotated on the outer surfaces on both sides of the connecting rotating tooth. There are two groups of meshing tooth rods, and plug - in plates are respectively fixedly added to the other ends of the two groups of meshing tooth rods. The outer surfaces at both ends of the plug - in plate are respectively movably inserted into the curved alloy elastic piece 223 and the inner wall of the battery installation housing 1; in this embodiment, after all the single - cell batteries are assembled, the top cover 12 is integrally fastened to the upper end of the battery installation housing 1. At this time, it is fastened by fastening bolts. Subsequently, the rotating rod can be held and rotated by hand, so that the connecting rotating tooth connected to the lower end of the rotating rod rotates clockwise. At this time, the two groups of meshing tooth rods that are mutually adapted on the side of the connecting rotating tooth move relatively inward and outward respectively, thereby driving the two plug - in plates to pass through the upper inner wall of the diversion hole 231 and continue to move outward until the plug - in plates pass through the upper inner wall of the battery installation housing 1, realizing the reinforced connection between the top cover 12 and the battery installation housing 1. And at this time, the upper ends of the multiple assembled strengthening installation frames 311 are restricted by the meshing tooth rods, ensuring that the battery will not be easily displaced, further improving the layout management of the sodium - ion battery and having higher stability.

[0050] Embodiment 3, referring to the attached Figure 1-19 , on the basis of Embodiment 2, in order to realize the frame support for the sodium - ion battery power supply to ensure sufficient structural strength of the battery pack: There are two groups of inner frame side plates 21, and the lower ends of the two groups of inner frame side plates 21 are respectively fixedly connected to the inner cavity bottom surface of the battery installation housing 1.

Connecting side frames 222 are respectively fixedly installed at both ends of the positioning truss 22. A curved alloy elastic piece 223 is fixedly connected to the inner side of the connecting side frame 222. The other end of the curved alloy elastic piece 223 is fixedly connected to the outer surface of one side of the diversion plate 23. Diversion holes 231 are uniformly opened on the inner wall of the diversion plate 23; in this embodiment, the two groups of inner frame side plates 21 are used as vertical support elements, and the heat - dissipation fan group 211 is installed on their inner walls. The ventilation environment inside the battery installation housing 1 is strengthened by cooperating with the ventilation openings opened on the inner wall of the battery installation housing 1, avoiding the accumulation of heat inside the battery installation housing 1 from affecting the use effect of the battery components. The positioning truss 22 is connected with the two groups of inner frame side plates 21 for limiting connection to form a protective frame for the battery components. By adding two groups of diversion plates 23 inside the inner frame side plates 21 and through the uniformly opened diversion holes 231 on the inner wall of the diversion plate 23, the guiding flow of the air flow blown by the heat - dissipation fan group 211 around the battery components is effectively realized, further stabilizing the operating performance of the sodium - ion battery power supply.

[0051] Embodiment 4. Referring to the appendix Figure 1-19 , on the basis of Embodiment 3, in order to ensure the isolated storage of the sodium-ion battery power monomer and achieve a portable disassembly and assembly effect: The monomer assembly unit 31 includes a reinforced installation frame 311. A pull ring 312 is fixedly installed on the outer surface of the upper end of the reinforced installation frame 311. The outer surface of the lower end of the reinforced installation frame 311 is respectively movably clamped with a card slot fixedly installed on the inner cavity bottom surface of the battery installation housing 1. Side vertical grooves 3111 and side grooves 3112 are respectively opened on the inner wall of the reinforced installation frame 311. An explosion-proof support plate 3113 is arranged on the inner surface of the side groove 3112. Reinforcing ribs 3114 are respectively fixedly installed on the outer surfaces of both ends of the explosion-proof support plate 3113, and the other ends of the reinforcing ribs 3114 are respectively fixedly connected to the inner wall of the side groove 3112. A connecting member 321 is fixedly installed on the upper end of the sodium-ion battery pack 32. The outer surface on the upper side of the connecting member 321 is respectively movably embedded with the inner wall of the upper end of the reinforced installation frame 311. The sodium-ion battery pack 32 is movably installed inside the reinforced installation frame 311. Buffer coating seats 322 are respectively movably clamped on the outer surfaces of both ends of the sodium-ion battery pack 32. The buffer coating seats 322 are respectively fixedly installed on the inner side top surface and the inner side bottom surface of the reinforced installation frame 311. The partitioning unit 33 includes a hollow corrugated partition plate 331. The outer surface of the lower end of the hollow corrugated partition plate 331 is fixedly connected to the inner cavity bottom surface of the battery installation housing 1. A reinforcing core plate 332 is fixedly installed at the center of the inner cavity of the hollow corrugated partition plate 331, and circular through holes are uniformly opened on the inner walls of the hollow corrugated partition plate 331 and the reinforcing core plate 332. Buffer components 333 are respectively arranged on the outer surfaces of both sides of the hollow corrugated partition plate 331. A T-shaped groove is arranged on the inner wall of the hollow corrugated partition plate 331; in this embodiment, the sodium-ion battery pack 32 is separated and stored by the separately provided reinforced installation frame 311, strengthening the structural installation strength of the sodium-ion battery pack 32. The side vertical grooves 3111 and side grooves 3112 opened on the inner wall of the reinforced installation frame 311 can, on the one hand, achieve the ventilation cycle of the sodium-ion battery pack 32 and avoid the accumulation of heat during use, and on the other hand, can reduce the overall weight of the reinforced installation frame 311. The reinforced installation frame 311 is made of a lightweight but strong material, such as aluminum alloy or high-strength plastic, to reduce the overall weight while ensuring sufficient structural strength. And the wrapping and isolation of both ends of the sodium-ion battery pack 32 are realized through the connecting member 321, ensuring the overall installation stability of the sodium-ion battery pack 32. Subsequently, the sodium-ion battery packs 32 assembled inside the hollow corrugated partition plate 331 are isolated by the hollow corrugated partition plate 331 in adjacent positions. The hollow corrugated partition plate 331 is designed with a corrugated structure as a whole, and the gaps can allow the air flow to circulate. At the same time, the reinforcing core plate 332 is relied on to realize the reinforcement and support of the hollow corrugated partition plate 331, further improving the isolation effect between adjacent reinforced installation frames 311 and avoiding the deformation of the hollow corrugated partition plate 331 affected by external impact forces.

[0052] Example 5, referring to the appendix Figure 1-19, on the basis of Embodiment 4, in order to strengthen the buffering protection of the reinforcement installation frame 311 and the internal flow guide plate 23 and prevent the sodium-ion battery power supply from shaking during movement: The buffer assembly 333 includes a curved buffer contact plate 3331 and a movable toothed plate 3332. Limiting support assemblies are respectively arranged on the lower surfaces of both ends of the curved buffer contact plate 3331. The movable toothed plate 3332 is arranged inside the curved buffer contact plate 3331. One end of the movable toothed plate 3332 away from the curved buffer contact plate 3331 is movably connected to the inner wall of the T-shaped groove. A limiting side block 3311 is fixedly added to the inner surface of the T-shaped groove. The outer surface of the limiting side block 3311 is slidably connected to the outer surfaces of both sides of the movable toothed plate 3332. Meshing rotating teeth 3333 are meshed and rotated on the outer surfaces of both sides of the movable toothed plate 3332. A gear connecting rod 3334 is fixedly installed on the meshing rotating teeth 3333. The other end of the gear connecting rod 3334 is rotatably installed with a guide wheel 3335. The outer surface of the guide wheel 3335 is movably connected to the inner ring surface of the curved buffer contact plate 3331. Movable support arms 3336 are rotatably installed on the outer surfaces of both sides of the gear connecting rod 3334. The other end of the movable support arm 3336 is hinged with a slider 3337. The lower outer surface of the slider 3337 is respectively slidably connected to the inner wall of the T-shaped groove. A buffer spring wire 3338 is fixedly installed on the outer surface of the slider 3337. The other end of the buffer spring wire 3338 is fixedly connected to the inner wall of the T-shaped groove;In this embodiment, multiple sets of buffer components 333 are additionally arranged between the wave gaps of the hollow wave partition plate 331. When the reinforced installation frame 311 expands due to the influence of high temperature or an abnormal fire occurs, causing deformation and damage to the deflector 23 and the reinforced installation frame 311, the hollow wave partition plate 331 installed between the reinforced installation frames 311 isolates the deflector 23 in an abnormal state, avoiding causing collateral damage to other battery monomers. When the curved buffer contact plate 3331 is subjected to an external impact force, the curved buffer contact plate 3331 is pushed inward, and an inward pushing force is applied to the movable toothed plate 3332. The movable toothed plate 3332 slides on the inner wall of the T-shaped groove opened on the inner side wall of the hollow wave partition plate 331. At this time, the limit side block 3311 acts as a limiting member and slides adaptively with the inner walls on both sides of the movable toothed plate 3332. Subsequently, the lower inner side of the movable toothed plate 3332 moves, driving the meshing rotating teeth 3333 on both sides to rotate adaptively, thereby changing the angle of the gear connecting rod 3334. And at this time, the guide wheel 3335 connected to one end of the gear connecting rod 3334 abuts against the inner annular surface of the curved buffer contact plate 3331. The guide wheel 3335 provides a reverse pushing force for the curved buffer contact plate 3331 to maintain the support strength of the curved buffer contact plate 3331. And when the angle of the gear connecting rod 3334 changes, the movable support arm 3336 connected to the gear connecting rod 3334 pushes the slider 3337 connected to the other end to slide on the inner wall of the T-shaped groove. At this time, the buffer spring wire 3338 is affected by the pushing force and also generates a reaction force to support the gear connecting rod 3334 and the guide wheel 3335, further strengthening the support for the curved buffer contact plate 3331, thereby realizing the buffer protection for the reinforced installation frame 311.;

[0053] Embodiment Six. Refer to the appendix Figure 1-19 , on the basis of Embodiment Five, this embodiment adds a limit support component: The limit support component includes a fixed sleeve fixedly installed on the outer surface of the hollow wave partition plate 331. A buffer damper is fixedly installed on the bottom surface of the inner cavity of the fixed sleeve. The other end of the buffer damper is fixedly installed with an abutting rod slidably connected to the fixed sleeve. The outer surface of the end of the abutting rod away from the buffer damper is fixedly connected to the inner annular surface of the curved buffer contact plate 3331; In this embodiment, by adding a limit support component at both inner ends of the curved buffer contact plate 3331, it can effectively ensure that when the curved buffer contact plate 3331 abuts against the external reinforced installation frame 311 and external components, it effectively guarantees the extrusion balance of the curved buffer contact plate 3331, ensuring that it will not tilt after being subjected to an external force, and at the same time, ensuring that the curved buffer contact plate 3331 is uniformly stressed. The resulting reverse elastic force realizes the stable limit protection for the side of the reinforced installation frame 311.
