Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a packaging structure and a sodium-ion solid-state battery. Background Technology

[0002] Sodium-ion solid-state batteries are a new type of battery technology that uses solid electrolytes instead of liquid electrolytes. They have advantages such as high safety, high stability and high energy density. In the manufacturing process of sodium-ion solid-state batteries, after the battery pack is made, it is necessary to encapsulate the battery pack through a packaging structure to ensure the safety and stability of the battery.

[0003] The existing packaging structure rigidly fixes the battery pack after encapsulating the sodium-ion solid-state battery. This makes the encapsulated sodium-ion solid-state battery prone to damage when it is subjected to impact during use. In addition, the existing packaging structure only uses simple heat dissipation holes to dissipate heat during battery use, and the heat dissipation effect needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the problems that the encapsulated sodium-ion solid-state battery is prone to damage when subjected to impact during use, and that the existing encapsulation structure only uses simple heat dissipation holes to achieve heat dissipation during battery use, with the heat dissipation effect needing improvement. This invention provides an encapsulation structure and a sodium-ion solid-state battery.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An encapsulation structure and a sodium-ion solid-state battery include a frame with uniformly spaced placement slots inside. Squeezing plates are symmetrically and slidably connected to the front and rear sides of each placement slot. Columns are symmetrically and fixedly installed on the upper and lower sides of the end of each squeezing plate near the inner wall of the frame. The squeezing plates are slidably connected to the inner wall of the frame via the columns. A spring is fixedly connected between the end of each squeezing plate near the inner wall of the frame and the inner wall. An airbag is fixedly connected between the squeezing plates and the inner wall of the frame. A battery pack is secured between the squeezing plates inside the placement slots. A cover plate is secured to the top of the frame. Connectors are symmetrically and fixedly installed on the top of the cover plate.

[0007] Furthermore, inclined bevels are provided on the upper and lower sides of the adjacent ends of the front and rear extrusion plates, so that the extrusion plates can be pushed to the sides by the inclined bevels during the downward insertion and assembly of the battery pack.

[0008] Furthermore, the airbag is located between the middle of the extrusion plate and the inner wall of the frame, and the spring and the column are symmetrically distributed on the upper and lower sides of the airbag.

[0009] Furthermore, symmetrical limit posts are fixedly connected to the left and right sides of the bottom end of the cover plate, and symmetrical limit grooves are opened on the left and right sides of the top of the frame, with the limit posts and limit grooves aligned to achieve precise assembly of the cover plate and the frame.

[0010] Furthermore, the bottom of the cover plate is elastically limited and slidably connected with locking blocks on the left and right sides, and the top of the frame is provided with grooves on the left and right sidewalls, and the locking blocks are aligned with the grooves. Through the cooperation of the locking blocks and the grooves, the cover plate and the frame are locked and connected.

[0011] Furthermore, ventilation groove 1 is provided in the side walls on the front and rear sides of the frame. The upper part of ventilation groove 1 extends upward to the top of the frame, and the lower part of ventilation groove 1 bends inward and connects with the interior of the airbag. Ventilation groove 2 is provided in the front and rear sides of the cover plate. The lower part of ventilation groove 2 connects with the upper part of ventilation groove 1, and the upper part of ventilation groove 2 bends outward and extends to the front and rear ends of the cover plate. Therefore, when the airbag is compressed and deformed, the air inside the frame can flow through ventilation groove 1 and ventilation groove 2, thereby improving the heat dissipation effect.

[0012] Furthermore, a contact plate is elastically and slidably connected at the center of the bottom of the cover plate, and an electrical contact strip is fixedly connected to the bottom end of the contact plate. The electrical contact strip is used to electrically connect with the battery pack and realize the series connection of the battery pack.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the design of the extrusion plates elastically connected on both sides of the limiting groove inside the frame, can buffer the shaking generated by the internal battery pack during the use of the solid-state battery. In the event of an impact, it can buffer and protect the internal battery pack, preventing damage to the battery pack. During the process of the extrusion plates moving to buffer the battery pack, the combination of airbags and ventilation grooves can accelerate the exchange of air between the inside of the frame and the outside, thereby improving the heat dissipation effect of the solid-state battery during use.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] A preferred embodiment of the present invention, including its encapsulation structure and sodium-ion solid-state battery, will be described in detail below. Figures 1-8 As shown, a packaging structure and sodium-ion solid battery include a frame 1. The frame 1 has uniformly opened placement grooves 2 inside. The front and rear sides of the placement grooves 2 are symmetrically limited and slidably connected with extrusion plates 3. The upper and lower sides of the adjacent end of the extrusion plates 3 on the front and rear sides are provided with inclined bevels, so that during the process of inserting and assembling the battery pack 7 downwards, the extrusion plates 3 can be pushed to the sides by the inclined bevels.

[0026] The extrusion plate 3 is symmetrically fixedly installed with columns 4 on the upper and lower sides of the end near the inner wall of the frame 1. The extrusion plate 3 is limited and slidably connected to the inner wall of the frame 1 by the columns 4. A spring 5 is fixedly connected between the end of the extrusion plate 3 near the inner wall of the frame 1 and the inner wall of the frame 1. An airbag 6 is fixedly connected between the extrusion plate 3 and the inner wall of the frame 1. The airbag 6 is located between the middle of the extrusion plate 3 and the inner wall of the frame 1. The spring 5 and the columns 4 are symmetrically distributed on the upper and lower sides of the airbag 6.

[0027] The battery pack 7 is locked between the extrusion plates 3 inside the placement slot 2. The top of the frame 1 is locked with a cover plate 8. Connectors 9 are symmetrically fixed on the top of the cover plate 8. Limiting posts 10 are symmetrically fixed on the left and right sides of the bottom of the cover plate 8. Limiting grooves 11 are symmetrically opened on the left and right sides of the top of the frame 1, and the limiting posts 10 and the limiting grooves 11 are aligned to achieve precise assembly of the cover plate 8 and the frame 1.

[0028] The bottom left and right sides of the cover plate 8 are elastically limited and slidably connected with locking blocks 12. The side walls on the top left and right sides of the frame 1 are provided with grooves 13, and the locking blocks 12 and the grooves 13 are aligned. Through the cooperation of the locking blocks 12 and the grooves 13, the cover plate 8 and the frame 1 are limited and locked.

[0029] Ventilation slots 14 are provided on the side walls of the front and rear sides of the frame 1. The upper part of the ventilation slots 14 extends upward to the top of the frame 1, and the lower part of the ventilation slots 14 bends inward and connects with the interior of the airbag 6. Ventilation slots 25 are provided on the front and rear sides of the cover plate 8. The lower part of the ventilation slots 215 connects with the upper part of the ventilation slots 14, and the upper part of the ventilation slots 215 bends outward and extends to the front and rear ends of the cover plate 8. Therefore, when the airbag 6 is compressed and deformed, the air inside the frame 1 can flow through the ventilation slots 14 and 215, thereby improving the heat dissipation effect.

[0030] A contact plate 16 is elastically and slidably connected at the center of the bottom of the cover plate 8. An electric contact strip 17 is fixedly connected to the bottom end of the contact plate 16. The electric contact strip 17 is used to electrically connect with the battery pack 7 and realize the series connection of the battery pack 7.

[0031] The working principle of this utility model is as follows:

[0032] During assembly, the battery pack 7 is inserted downwards into the placement slot 2. During the downward insertion process, the inclined bevels on the upper and lower sides of the adjacent end of the extrusion plate 3 can push the extrusion plate 3 to compress the spring 5 to both sides. After placement is completed, the spring 5 causes the extrusion plate 3 to compress and fix the battery pack 7.

[0033] Then, through the cooperation of the limiting post 10 and the limiting groove 11, the cover plate 8 is precisely aligned with the frame 1 and moved downward. During the pressing down of the cover plate 8, the locking blocks 12 on the left and right sides of the cover plate 8 will first retract and then pop outward at the groove 13. Thus, the locking blocks 12 and the groove 13 cooperate to achieve the limiting and locking of the cover plate 8 at the top of the frame 1.

[0034] When the cover plate 8 is snapped in place, the electrical contact strip 17 on the bottom contact plate 16 of the cover plate 8 is pressed into contact with the electrical contact at the top of the battery pack 7, thereby completing the interconnection of the assembled battery pack 7.

[0035] During the use of solid-state batteries, the compression plates 3 on both sides of the battery pack 7 and the springs 5 ​​can buffer the movement of the battery pack 7, thereby buffering the impact encountered by the solid-state battery and preventing damage to the internal battery pack 7. At the same time, during the process of the compression plates 3 moving to buffer the battery pack 7, the air bladder 6 between the compression plates 3 and the inner wall of the frame 1 can be alternately compressed, causing the air bladder 6 to deform. In conjunction with the function of the ventilation groove 14 and the ventilation groove 15, the air inside the frame 1 can be exchanged with the outside, thereby improving the heat dissipation effect of the battery pack 7 inside the frame 1 during use.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
