Description

Technical Field

[0001] The present invention relates to the technical field of solid-state lithium batteries, and specifically to a solid-state lithium battery with a fast heat dissipation function. Background Art

[0002] "Lithium battery" is a type of battery with a lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have now become the mainstream.

[0003] For example, in the Chinese patent with the publication number CN212257608U and the name "A Lithium Battery with a Heat Dissipation Function", it includes a lithium battery housing. A small motor is fixedly connected to the left inner wall of the lithium battery housing. A fixing ring is fixedly connected to the outer surface of the main shaft of the small motor. A plurality of heat dissipation fan blades are fixedly connected to the outer surface of the fixing ring. A support plate is fixedly connected to the left end of the inner bottom wall of the lithium battery housing. A plurality of first heat dissipation holes are opened on the left side of the support plate. A connection hole is opened at the left end of the top of the lithium battery housing. A connection groove is opened on the top of the support plate. A connection block is detachably and fixedly connected to the inner surface of the connection groove. For this lithium battery with a heat dissipation function, through the structure of the connection groove, connection block, cover plate, groove, connection shaft, handle, and support block, it is convenient to remove the cover plate and facilitate the maintenance and replacement of the small motor inside the lithium battery housing.

[0004] Although the lithium battery with a heat dissipation function in the above patent is practical and convenient, it also has deficiencies. When a solid-state lithium battery fails, it is necessary to disassemble the solid-state lithium battery pack from the battery box. However, usually, the bottom of the solid-state lithium battery is tightly adhered to the battery box through adhesive strips, and due to the narrow packaging space, it is difficult for workers to reach into the box to remove the adhesive strips. They can only violently tear the plastic packaging outside the solid-state lithium battery or even need to disassemble the bottom of the box to poke out the battery pack. Violent disassembly and assembly are likely to damage the lithium battery or the battery box. Summary of the Invention

[0005] The purpose of the present invention is to provide a solid-state lithium battery with a fast heat dissipation function to solve the deficiencies in the above-mentioned prior art.

[0009] Further, the two locking members each include an insertion rod, a fixed block, and an abutting block. The fixed block is fixedly connected to one side of the sleeve. A second elastic member is provided between the fixed block and the abutting block. The abutting block is slidably connected to one side of the sleeve. The insertion rod is slidably connected in the sleeve through a third elastic member, and the insertion rod is in plug-in fit with the second hinge rod. One end of the insertion rod close to the abutting block is inclined, and the abutting block is in sliding abutting fit with one end of the insertion rod.

[0010] Further, the lifting assembly includes an incomplete bevel gear, a bevel gear body meshed with the incomplete bevel gear, a screw rod, a second slider, and two lifting plates.

Detailed implementation manners

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0020] Please refer to Figure 1-15 , a technical solution provided by an embodiment of the present invention: The solid-state lithium battery with a fast heat dissipation function includes a box body 1, a box cover 2 hinged to the top of the box body 1, a transmission assembly, a linkage assembly, and a lifting assembly. During the opening process of the box cover 2 relative to the box body 1, it sequentially has a first stroke and a second stroke. Two clamping plates 6 are horizontally and reversely slidably connected in the box body 1, and two cutting knives 7 are horizontally and reversely slidably connected in the box body 1. Moreover, the two clamping plates 6 and the two cutting knives 7 correspond one by one and have opposite sliding directions. The transmission assembly is driven during the opening process of the box cover 2 to make the two clamping plates 6 slide away from each other. The linkage assembly is driven by the sliding of the two clamping plates 6 away from each other to make the two cutting knives 7 slide closer to cut the rubber strip 5 at the bottom of the battery pack 4. The lifting assembly is driven by the second stroke during the opening process of the box cover 2 to make the two cutting knives 7 move vertically upward. Specifically, the surface of the cutting knife 7 is coated with an anti-sticking coating to avoid sticking to the rubber strip 5. Heat dissipation holes 3 for heat dissipation and ventilation are provided on both sides of the box body 1.

[0021] As a preferred technical solution, the transmission assembly includes a rotating rod 8 and two first sliders 9. The rotating rod 8 is rotatably connected to the box body 1, and the box cover 2 is hinged to the box body 1 through the rotating rod 8. Two first spiral grooves 10 are symmetrically formed on the rotating rod 8. A first protrusion is provided in each of the two first sliders 9, and the two first protrusions are slidably connected to the two first spiral grooves 10 in a one-to-one correspondence. Two first sliding grooves 11 are horizontally and symmetrically formed in the box body 1, and the two first sliders 9 are slidably connected to the two first sliding grooves 11 in a one-to-one correspondence. The two first sliders 9 are fixedly connected to the two clamping plates 6 in a one-to-one correspondence. Specifically, when it is necessary to disassemble and repair the battery pack 4, the box cover 2 is opened to drive the rotating rod 8 to rotate. Since the first sliding groove 11 restricts the circumferential rotation of the first slider 9, the two first sliders 9 are driven to slide reversely through the spiral transmission of the rotating rod 8, driving the two clamping plates 6 to loosen the clamping and fixing of the battery pack 4, expanding the encapsulation space and facilitating the worker to reach into the box to take the battery pack 4.

[0022] As a preferred technical solution, the linkage assembly includes two first hinge rods 14, two second hinge rods 15, a first connecting block 16 and a second connecting block 17. The first connecting block 16 and the second connecting block 17 are vertically slidably connected in the box body 1. A first elastic member 21 is provided between the first connecting block 16 and the second connecting block 17. One end of each of the two first hinge rods 14 is hinged to the two clamping plates 6 in a one-to-one correspondence. The other ends of the two first hinge rods 14 are both hinged to the first connecting block 16. One end of each of the two second hinge rods 15 is hinged to the second connecting block 17. A mounting seat is fixedly connected to one side of each of the two cutting knives 7. A set of parts 25 is sleeved on each of the two second hinge rods 15. A locking member is provided between each of the two sets of parts 25 and the two second hinge rods 15. A cylinder 27 is fixedly connected to one side of each of the two sets of parts 25. A sliding column 28 is sleeved on each of the two cylinders 27. The two sliding columns 28 are hinged to the two mounting seats in a one-to-one correspondence. A sliding hole 23 is formed at the other end of each of the two second hinge rods 15. The two sliding columns 28 are movably connected to the two sliding holes 23 in a one-to-one correspondence. Specifically, the first elastic member 21 includes a telescopic rod and a spring sleeved on the telescopic rod. Two ends of the telescopic rod are respectively fixedly connected to the top of the first connecting block 16 and the bottom of the second connecting block 17. Two first guiding grooves 32 are symmetrically and horizontally formed in the box body 1. The two mounting seats are horizontally slidably connected to the two first guiding grooves 32 in a one-to-one correspondence. A second guiding groove 33 is vertically formed in the box body 1. The first connecting block 16 and the second connecting block 17 are both vertically slidably connected in the second guiding groove 33, and the first connecting block 16 is located below the second connecting block 17. The two clamping plates 6 move away from each other, driving the first connecting block 16 to move upward through the two first hinge rods 14, driving the second connecting block 17 to move upward through the first elastic member 21. The second connecting block 17 drives the closer ends of the two second hinge rods 15 to move vertically upward. And the set of parts 25 is fixed to the other end of the second hinge rod 15 through the locking member. The horizontal position of the other end of the second hinge rod 15 is changing. Since the first guiding groove 32 restricts the mounting seat to only move in a horizontal straight line, and the set of parts 25 drives the sliding column 28 to move horizontally through the cylinder 27, and the sliding column 28 drives the cutting knife 7 to move horizontally through the mounting seat. The two cutting knives 7 move closer to cut the rubber strip 5 at the bottom of the battery pack 4, avoiding deformation of the box body 1 caused by forced disassembly. The two cutting knives 7 are kept parallel to the glue surface to prevent scratching of the internal components.

[0023] As a preferred technical solution, both locking members include an insertion rod 37, a fixed block 26 and an abutting block 36. The fixed block 26 is fixedly connected to one side of the kit 25. A second elastic member 22 is provided between the fixed block 26 and the abutting block 36. The abutting block 36 is slidably connected to one side of the kit 25. The insertion rod 37 is slidably connected to the inside of the kit 25 through a third elastic member 39, and the insertion rod 37 is inserted and matched with the second hinge rod 15. One end of the insertion rod 37 close to the abutting block 36 is inclined, and the abutting block 36 is slidably abutted and matched with one end of the insertion rod 37. Specifically, the third elastic member 39 includes a spring, the spring is sleeved on the insertion rod 37, a guide ring 38 is sleeved on the insertion rod 37, a groove 40 is horizontally opened in the kit 25, and the guide ring 38 is slidably connected to the groove 40. Two ends of the spring are respectively fixedly connected to the groove wall of the groove 40 and one end of the guide ring 38. The second elastic member 22 includes a telescopic rod and a spring sleeved on the telescopic rod. Two ends of the telescopic rod are respectively fixedly connected to the fixed block 26 and the abutting block 36. Through the second elastic member 22, the abutting block 36 is blocked at the outlet of the groove 40, and the kit 25 is fixed to the other end of the second hinge rod 15 through the insertion rod 37, avoiding relative sliding between the sliding column 28 and the sliding hole 23 during the cutting process of the cutting knife 7.

[0024] As a preferred technical solution, the lifting assembly includes an incomplete bevel gear 41, a bevel gear body 12 meshing with the incomplete bevel gear 41, a screw rod 13, a second slider 19, and two lifting plates 20. The incomplete bevel gear 41 is sleeved on the rotating rod 8. The bevel gear body 12 is horizontally rotatably connected in the box body 1. The screw rod 13 is coaxially and fixedly connected to the bottom end of the bevel gear body 12. A second helical groove 18 is formed on the screw rod 13. A second protrusion is provided in the second slider 19, and the second protrusion is slidably connected to the second helical groove 18. A second chute 35 is vertically formed in the box body 1, and the second slider 19 is slidably connected in the second chute 35. The two lifting plates 20 are fixedly connected to one side of the second slider 19. The tops of the two lifting plates 20 are in abutting cooperation with the bottoms of the two abutting blocks 36. Specifically, in the first stroke of the rotation of the box cover 2, the incomplete bevel gear 41 does not mesh with the bevel gear body 12. When the box cover 2 starts to rotate in the second stroke, the incomplete bevel gear 41 meshes with the bevel gear body 12. At this time, the top of the second connecting block 17 abuts against the top wall of the second guiding groove 33. The two second hinge rods 15 are in a vertical state, and the kit 25 is also in a vertical state. The bevel gear body 12 drives the screw rod 13 to rotate. The second chute 35 restricts the circumferential rotation of the second slider 19. The second slider 19 is driven to move vertically upward through screw drive, and at the same time, the two lifting plates 20 are driven to move vertically upward. The two lifting plates 20 first abut against the two abutting blocks 36 and drive the two abutting blocks 36 to move upward, and the abutting blocks 36 no longer block the groove 40. The insertion rod 37 disengages from the insertion connection with the second hinge rod 15 through the third elastic member 39, releasing the locking of the kit 25 and the second hinge rod 15. Then, the kit 25 is driven to move upward through the fixing block 26, and at the same time, the cutting knife 7 is driven to move upward through the mounting seat. On the one hand, it is convenient to clean the residual rubber strip 5 below. On the other hand, the cutting knife 7 can lift the battery pack 4 with a lighter weight, and the worker does not need to reach into the battery box by hand and can exert force better to disassemble the battery pack 4. During the reset process, the cutting knife 7 drives the kit 25 to move vertically downward by its own gravity. When the abutting block 36 abuts against the inclined end of the insertion rod 37, the insertion rod 37 is driven to move toward the second hinge rod 15 by extrusion. When the abutting block 36 blocks the outlet of the groove 40, the locking of the kit 25 and the second hinge rod 15 is completed, avoiding the relative sliding of the sliding column 28 and the sliding hole 23 during the reset process and preventing the cutting knife 7 from being reset. During this process, the first elastic assembly can realize the relative displacement of the first connecting block 16 and the second connecting block 17 in the vertical direction. Preferably, two third guiding grooves 34 are symmetrically and vertically formed in the box body 1, and the two lifting plates 20 are respectively slidably connected in the two third guiding grooves 34. During the vertical movement of the two mounting seats, the two mounting seats are vertically slidably connected in the two second guiding grooves 33, and the two second guiding grooves 33 restrict the circumferential rotation of the two mounting seats, keeping the cutting knife 7 horizontal.

[0025] As a preferred technical solution, both mounting seats include two connecting plates 30 and a rotating shaft 29. The rotating shaft 29 is rotatably connected within the sliding column 28. The two connecting plates 30 are symmetrically sleeved on the rotating shaft 29. A spur gear 31 is sleeved on each of the two rotating shafts 29. A rack 24 is provided on one side of each of the two second hinge rods 15 close to the battery pack 4. The two racks 24 are meshed and connected with the two spur gears 31 in a one-to-one correspondence. Specifically, after the battery pack 4 is removed, the box cover 2 can be continuously rotated to drive the cutting knife 7 to continue moving upward. At this time, the spur gear 31 is meshed with the rack 24, and the cutting knife 7 is driven to rotate upward through the rotating shaft 29, further opening the internal space of the box body 1, facilitating the replacement of the rubber strip 5 inside the box body 1 and the maintenance of components.

[0026] Working principle: When the invention works, the battery pack 4 is stably clamped by the clamping plates 6. When disassembly and maintenance are required, first open the box cover 2 by ninety degrees. During this process, the two first sliders 9 are driven to slide reversely through the screw drive of the rotating rod 8, driving the two clamping plates 6 to release the clamping and fixing of the battery pack 4, expanding the encapsulation space, facilitating the worker to reach into the box to take the battery pack 4. The two first hinge rods 14 drive the first connecting block 16 to move upward, driving the second connecting block 17 to move upward through the first elastic member 21. The second connecting block 17 drives the ends of the two second hinge rods 15 close to each other to move vertically upward. And the kit 25 is fixed to the other end of the second hinge rod 15 through the locking member. The horizontal position of the other end of the second hinge rod 15 is changing. The kit 25 drives the sliding column 28 to move horizontally through the cylinder 27. The sliding column 28 drives the cutting knife 7 to move horizontally through the mounting seat. The two cutting knives 7 move closer to cut the rubber strip 5 at the bottom of the battery pack 4, avoiding deformation of the box body 1 caused by forced disassembly. The two cutting knives 7 keep parallel to the glue surface to prevent scratching the internal components. Continue to rotate the box cover 2, and the incomplete bevel gear 41 meshes with the bevel gear body 12. At this time, the top of the second connecting block 17 abuts against the top wall of the second guide groove 33. The two second hinge rods 15 are in a vertical state, and the kit 25 is also in a vertical state. The bevel gear body 12 drives the screw rod 13 to rotate, driving the second slider 19 to move vertically upward through the screw drive, and at the same time driving the two lifting plates 20 to move vertically upward. The two lifting plates 20 first abut against the two abutting blocks 36 and drive the two abutting blocks 36 to move upward. And the abutting blocks 36 no longer block the groove 40. The insertion rod 37 disengages from the insertion with the second hinge rod 15 through the third elastic member 39, releasing the locking of the kit 25 and the second hinge rod 15. Then drive the kit 25 to move upward through the fixing block 26, and at the same time drive the cutting knife 7 to move upward through the mounting seat. On the one hand, it is convenient to clean the remaining rubber strip 5 below. On the other hand, the cutting knife 7 can lift the battery pack 4 with a lighter weight. The worker does not need to reach into the battery box, and can better exert force to disassemble the battery pack 4. After disassembling the battery pack 4, the box cover 2 can be continuously rotated to drive the cutting knife 7 to continue to move upward. At this time, the spur gear 31 meshes with the rack 24, driving the cutting knife 7 to rotate upward through the rotating shaft 29, making the cutting knife 7 in a vertical state, further opening the internal space of the box body 1, facilitating the replacement of the rubber strip 5 inside the box body 1 and the maintenance of the components.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
