Technical Field

[0001] This utility model relates to the field of solid-state battery technology, and in particular to an easy-to-maintain all-solid-state battery. Background Technology

[0002] Solid-state batteries are batteries that use solid electrodes and solid electrolytes. Unlike traditional lithium-ion batteries and lithium-ion polymer batteries, there is no liquid inside them. The electrolyte of solid-state batteries is composed of inorganic or organic polymer solids. This design improvement gives solid-state batteries significant advantages in terms of safety, energy density and cycle performance.

[0003] However, in existing devices, the casing of most all-solid-state batteries is sealed by welding or bolts, which makes it inconvenient to disassemble and maintain the solid-state battery. Therefore, an all-solid-state battery that is easy to maintain is proposed. Utility Model Content

[0020] 1. Compared with existing technologies, this easy-to-maintain all-solid-state battery uses a rotating shaft, knob, rotating disk, sliding rod, sliding column, locking pin, and first spring. Rotating the knob drives the rotating disk to rotate via the rotating shaft. The rotating disk moves the sliding column via the arc groove. The sliding column moves the sliding rod, which in turn moves the locking pin and compresses the first spring, causing the two locking pins to disengage from their corresponding locking holes. Then, the cover plate can be removed, allowing staff to quickly remove the cover plate for maintenance of the solid-state battery body.

[0021] 2. Compared with existing technologies, this easy-to-maintain all-solid-state battery, by setting a second spring and a sealing frame, etc., when the cover plate is closed, the cover plate presses down on the sealing frame, and the sealing frame presses down on multiple second springs. Through the elasticity of multiple second springs, the sealing gasket on the sealing frame is tightly attached to the bottom of the cover plate, thereby improving the sealing performance between the outer shell and the cover plate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Reference Figures 1 to 6This utility model provides an easy-to-maintain all-solid-state battery: including a shell 1 and a cover plate 2. A battery groove 10 is opened on the upper surface of the shell 1. A solid-state battery body 11 is fixedly connected to the bottom of the battery groove 10. Four positioning plates 12 are fixedly connected to the outer side of the shell 1. When the cover plate 2 is closed, the positioning of the four positioning plates 12 prevents the cover plate 2 from shifting when pressing the sealing frame 9. A connecting post 3 is fixedly connected to the opposite side of the shell 1. A snap-fit ​​hole is opened on one side of each connecting post 3. Two electrode post grooves 13 are opened on the upper surface of the cover plate 2. Two protective rings 14 are fixedly connected to the upper surface of the cover plate 2. A sealing ring 15 is fixedly connected to the inner wall of each protective ring 14. The positive and negative electrode posts on the solid-state battery body 11 are respectively inserted into the electrode post grooves 13 and sealed by the sealing rings 15. A cross groove 4 is opened at the bottom of the cover plate 2. Two fixing plates 5 are fixedly connected to the top of the cross groove 4. A quick-release structure 6 is provided in the cross groove 4.

[0032] To achieve a seal, an extrusion groove 7 is provided on the upper surface of the outer shell 1. A sealing frame 9 is slidably connected inside the extrusion groove 7. A sealing gasket is fixedly provided on the upper surface of the sealing frame 9. A second spring 8 is fixedly connected to the bottom of the inner part of the extrusion groove 7. The other end of each second spring 8 is fixedly connected to the bottom of the sealing frame 9. When the cover plate 2 is closed, the cover plate 2 presses down on the sealing frame 9. The sealing frame 9 presses down on multiple second springs 8. Through the elasticity of multiple second springs 8, the sealing gasket on the sealing frame 9 is tightly attached to the bottom of the cover plate 2, thereby improving the sealing performance between the outer shell 1 and the cover plate 2.

[0033] To facilitate maintenance of the solid-state battery body 11, the quick-release structure 6 includes a rotating shaft 601 that is rotatably connected to the upper surface of the cover plate 2. A knob 602 is fixedly connected to the upper surface of the rotating shaft 601, and a rotating disk 603 is fixedly connected to the bottom of the rotating shaft 601. Two arc-shaped grooves are formed at the bottom of the rotating disk 603. A sliding rod 604 is slidably connected to one side of each fixed plate 5. A sliding post 605 is fixedly connected to one end of each sliding rod 604. Each sliding post 605 is slidably connected in a corresponding arc-shaped groove. A snap-fit ​​post 606 is fixedly connected to one side of each sliding rod 604. A first spring 607 is movably mounted on each sliding rod 604. One end of each first spring 607 is respectively connected to the corresponding arc-shaped groove. One side of the corresponding fixing plate 5 is fixedly connected, and the other end is fixedly connected to one side of the corresponding snap-fit ​​post 606. Each snap-fit ​​post 606 is slidably connected inside the cross groove 4 on the corresponding side. Each sliding rod 604 is adapted to the corresponding snap-fit ​​hole. Rotating the knob 602 causes the rotating disk 603 to rotate through the rotating shaft 601. The rotating disk 603 causes the sliding post 605 to move through the arc groove. The sliding post 605 causes the sliding rod 604 to move. The sliding rod 604 causes the snap-fit ​​post 606 to move and compress the first spring 607, so that the two snap-fit ​​posts 606 disengage from the corresponding snap-fit ​​holes. Then, the cover plate 2 is removed, which makes it convenient for the staff to quickly remove the cover plate 2 to maintain the solid-state battery body 11.

[0034] Working principle: Rotating knob 602 causes the rotating disk 603 to rotate via rotating shaft 601. The rotating disk 603 moves the sliding column 605 via the arc groove. The sliding column 605 moves the sliding rod 604. The sliding rod 604 moves the locking column 606 and compresses the first spring 607, causing the two locking columns 606 to disengage from their corresponding locking holes. Then, the cover plate 2 is removed, allowing staff to quickly remove the cover plate 2 for maintenance of the solid-state battery body 11. When the cover plate 2 is closed, it presses down on the sealing frame 9. The sealing frame 9 then presses down on multiple second springs 8. Through the elasticity of the multiple second springs 8, the sealing gasket on the sealing frame 9 is tightly attached to the bottom of the cover plate 2, improving the sealing between the outer shell 1 and the cover plate 2.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
