Description

Technical Field

[0001] The present invention belongs to the technical field of battery shock-absorbing devices, and particularly relates to a shock-absorbing device dedicated to cylindrical sodium-ion batteries and an operation method thereof. Background Art

[0002] A sodium-ion battery is a secondary battery (rechargeable battery) that mainly operates by the movement of sodium ions between the positive electrode and the negative electrode, similar to the working principle of a lithium-ion battery. It is one of the top ten emerging technologies in the field of chemistry in 2022.

[0003] The transportation of sodium-ion batteries requires strict compliance with relevant safety regulations and operation procedures to ensure the safety and efficiency of transportation. Before transportation, necessary inspections should be carried out on the batteries, and appropriate transportation methods and packaging methods should be selected. Sodium-ion batteries are generally packed in crates or fixed on pallets, and sponge blocks are added in the boxes for protection to provide sufficient physical protection.

[0004] However, when the vehicle encounters relatively rough road conditions, the absorption capacity of the sponge block will decrease and the buffering rate will decrease. At this time, the shock-absorbing effect of the crate or pallet is relatively poor, which may cause the sodium battery to be unstable, fall over, collide, resulting in losses or even danger.

[0015] An operating method of a special shock absorbing device for cylindrical sodium ion batteries comprises the following steps:

[0016] Step 1: Each sodium battery body is clamped onto each supporting member with a little force, and the serpentine plate contacts the sodium battery body at the same time, so that the supporting member will act as a buffer mechanism and change its structure. In a short time, the supporting member can be restored to its original position under the action of the buffer mechanism;

[0017] Step 2: Drive each handle to reduce the distance between the side panel 1 and the side panel 2 to the minimum value, that is, the side panel 1 and the side panel 2 are in a state of being in contact with each other, and then each half-moon block and the special buckle will contact and clamp the outer wall of each sodium battery body;

[0018] Step 3: Following step 2, start each electromagnetic device to overcome the elastic force of spring 2 so that side panel 1 and side panel 2 can be stably combined together, and then rotate the two limit handles to a vertical state to complete the operation steps.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When bumps occur during the transportation of the sodium battery body, the first shock-absorbing mechanism can reduce and absorb the shaking force of the sodium battery body in the surrounding directions and vertically upward, and the second shock-absorbing mechanism can reduce and absorb the force of the sodium battery body in the vertically downward direction, greatly reducing the risk of the sodium battery body falling off randomly, ensuring safety and reducing losses.

Detailed implementation manner

[0034] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Example 1, please refer to Figures 1 to 11, the present invention provides a technical solution: a special shock-absorbing device for cylindrical sodium-ion batteries, including a bottom box 1. A first shock-absorbing mechanism is arranged at the top of the bottom box 1. The first shock-absorbing mechanism includes a second side plate 3 and a first side plate 2. Three equally spaced partitions 23 are fixedly connected to the bottom end of the inner wall of the bottom box 1. Four shock-absorbing mechanisms with equal spacing are arranged inside the bottom box 1. Each shock-absorbing mechanism includes a buffer mechanism. The buffer mechanism includes a support plate 32 and a jacking plate 45. Four top plates 20 are fixedly connected to the top of the bottom box 1. A supporting member 53 is slidably connected to the inside of each top plate 20. Four sodium battery bodies 19 are arranged between the first side plate 2 and the second side plate 3. The sodium battery bodies 19 are clamped on the supporting members 53. The bottom end of the supporting member 53 is movably connected to the top of the jacking plate 45. Two square plates 48 are fixedly connected to the top of the bottom box 1. Both the first side plate 2 and the second side plate 3 are slidably connected to the square plates 48. A plurality of sodium battery bodies 19 are installed between the two square plates 48. When the sodium battery bodies 19 are jolted during transportation, through the arranged first shock-absorbing mechanism, the force of the sodium battery bodies 19 shaking in all directions and vertically upward can be reduced and absorbed. Through the arranged second shock-absorbing mechanism, the force of the sodium battery bodies 19 in the vertically downward direction can be reduced and absorbed, greatly reducing the risk of the sodium battery bodies 19 falling off randomly, ensuring safety and reducing losses.

[0036] Example 2, please refer to Figures 1 to 11, on the basis of the first embodiment, each top plate 20 is fixedly connected between the inner wall of the bottom box 1 and the partition 23, or between two adjacent partitions 23. Two sets of spaced and symmetrically distributed moving parts are arranged on the top of the support plate 32. Both sets of moving parts include two spaced and symmetrically positioned linkage mechanisms. The linkage mechanism includes a first convex block 33 and a second convex block 34. The positions of each second convex block 34 are all close to the middle of the support plate 32. A horizontal shaft rod is fixedly connected between the first convex block 33 and the second convex block 34. A driving block 36 and a synchronous block 39 are slidably connected to the outer wall of the horizontal shaft rod. One end of the driving block 36 is fixedly connected to the synchronous block 39. The driving block 36 is integrally U-shaped. A short shaft rod is rotatably connected between the inner walls on both sides of the driving block 36. A connecting block 37 is sleeved and slidably connected to the outer wall of the short shaft rod. A first spring 46 is slidably connected between the first convex block 33 and the driving block 36. The inner walls of the two connecting blocks 37 in the same set of moving parts are sleeved and slidably connected to the same connecting shaft 38. The outer wall of the connecting shaft 38 is rotatably connected to the inside of the jacking plate 45. A resisting block 47 is slidably connected between the bottom end of the driving block 36 and the top of the support plate 32. A first spring damper 35 is fixedly connected between the resisting block 47 and the first convex block 33. An inner groove 42 is formed at the middle position inside the support plate 32. An auxiliary block 41 is slidably connected to the inside of the inner groove 42. A plurality of rubber strips 44 are fixedly connected to the top of the auxiliary block 41. A plurality of equally spaced first spring dampers 43 are fixedly connected between the bottom end of the inner wall of the inner groove 42 and the auxiliary block 41. The top of the auxiliary block 41 passes through the top of the support plate 32. The cross-section of the part of the auxiliary block 41 exceeding the support plate 32 is an isosceles trapezoid. A trapezoidal block is movably connected to the outer wall of the inner groove 42. A second connecting rod 40 is fixedly connected between the trapezoidal block and the synchronous block 39. The cross-section of the second connecting rod 40 is L-shaped. The outer wall of the second connecting rod 40 is in a slidable connection relationship with the inside of the second convex block 34.In the initial state, each trapezoidal block is in contact with the inclined end of the auxiliary block 41. Each second spring damper 43 is in a compressed state, and each first spring damper 35 is in a normal unloaded state. When the sodium battery body 19 encounters bumps during transportation, it may tend to move vertically downward. Through the arranged supporting member 53, the sodium battery body 19 indirectly contacts the two lifting plates 45 and presses them down. The downward movement of the lifting plate 45 will drive each connecting block 37 to rotate around the connecting shaft 38. As the vertical height of the connecting block 37 decreases, its horizontal length will increase. Through the arranged driving block 36, first spring 46, abutting block 47, and first spring damper 35, the driving block 36 displaces toward both sides of the support plate 32 together with the connecting block 37 and compresses the first spring 46 and the first spring damper 35. Under the action of the first spring damper 35 and the first spring 46, the force generated by the displacement of the connecting block 37 is greatly reduced and then gradually absorbed. When this force disappears, the first spring damper 35 and the first spring 46 gradually return to their original positions, thereby pushing the lifting plate 45 back to its original position, and then sending the supporting member 53 and the sodium battery body 19 back to their original positions. During the above process, due to the displacement of each driving block 36, each synchronizing block 39 will displace synchronously in the same direction, so that the extrusion force on the auxiliary block 41 is gradually lost, and each second spring damper 43 also gradually returns to its original position and raises the vertical height of the auxiliary block 41. During the downward movement of the lifting plate 45, several rubber strips 44 will also contact its bottom end. Through the arranged second spring dampers 43, the downward force generated by the sodium battery body 19 is pushed in the opposite direction again to reduce the impact and achieve good shock absorption, reducing losses.

[0037] Embodiment 3. Please refer to Figures 1 to 11On the basis of the second embodiment, the internal space of the bottom box 1 forms a plurality of compartments 22 through a plurality of partitions 23, and the bottom ends of the inner walls of the compartments 22 are fixedly connected with two spaced-apart and symmetrically distributed vertical plates 1 24 and 29, and a shaft tooth column 28 is rotatably connected between the vertical plate 29 and the vertical plate 1 24, and a rack 1 25 and a rack 26 are meshed on the outer wall of the shaft tooth column 28, and the rack 1 25 and the rack 2 26 are both in a sliding connection with the vertical plate 1 24, and the positions of the rack 1 25 and the rack 2 26 are rotationally symmetrical about the axis of the shaft tooth column 28, and the top ends of the two racks 1 25 and the rack 2 26 are fixedly connected with a connecting rod 1 27, and the top ends of the connecting rods 1 27 at the tops of the racks 1 25 pass through the interior of the top plate 20 and are fixedly connected to the bottom ends of the side plates 1 2, and the top ends of the connecting rods 1 27 at the tops of the racks 1 25 pass through the interior of the top plate 20 and are fixedly connected to the bottom ends of the side plates 1 2. The top ends of the connecting rods 1 27 at the tops of the two racks 26 pass through the interior of the top plate 20 and are fixedly connected to the bottom ends of the side plates 23. The top of the top plate 20 is provided with a plurality of elliptical through grooves 21 for the two connecting rods 1 27 to slide. The outer wall of the shaft tooth column 28 is meshed with a rack 30. The position of the rack 30 is staggered with the rack 1 25 and the rack 2 26. The interior of the rack 30 is slidably connected with a reinforcing rod 31. The bottom end of the reinforcing rod 31 is fixedly connected to the bottom end of the inner wall of the compartment 22. The height of the reinforcing rod 31 is slightly smaller than the rack 30. The outer walls on both sides of the bottom box 1 are rotatably connected to the limiting handles 50. The two limiting handles 50 are in a sliding connection with the side panels 1 2 and 2 3. The outer walls of the side panels 1 2 and 2 3 are fixedly connected with two handles that are far away from each other and symmetrically positioned. It should be noted here that the length of the connecting rod 1 27 fixedly connected to the top of the rack 1 25 is greater than the length of the connecting rod 1 27 at the top of the rack 2 26 to match the working process of the rack 1 25 and the rack 2 26, and in the initial state, that is, when the sodium battery body 19 is running smoothly, the top of the rack 3 30 will not contact the supporting member 53, even when the supporting member 53 moves down to the lowest position, the two will not contact, and a part of the supporting member 53 is located inside the top plate 20 and the bottom box 1. When it is necessary to remove each sodium battery body 19, it is necessary to first adjust the two limit handles 50 that are stuck on the side plate 1 2 and the side plate 2 3, and rotate the two to a horizontal state. Then, the side panels 1 2 and 2 3 lose their limit, and then the two handles are pulled, so that the side panels 1 2 and 2 3 move away from each other. Under the connection of the elliptical through groove 21 and the connecting rod 1 27, the rack 1 25 is displaced together with the side panel 1 2, and the rack 2 26 is displaced together with the side panel 2 3. The displacement of the two causes the middle shaft tooth column 28 to rotate, thereby causing the meshing rack 3 30 to move vertically upward to increase the vertical height of the rack 3 30. The setting of the reinforcement rod 31 ensures that the displacement of the rack 3 30 is stable and smooth, and then the rack 3 30 will contact the supporting member 53 to completely push the sodium battery body 19 out of the bottom box 1, which is convenient for removal.

[0038] Example 4, please refer to Figures 1 to 11, on the basis of Embodiment 3, a meandering plate 4 is fixedly connected between two square plates 48. The cross-sectional shape of the meandering plate 4 is composed of two mirror-image S shapes combined. The meandering plate 4 can be evenly divided into four sections. A plurality of ventilation holes are provided on the side wall of the meandering plate 4. There are a total of four sodium battery bodies 19. The outer walls of two sodium battery bodies 19 are both in contact with the left outer wall of the meandering plate 4, and the outer walls of the other two sodium battery bodies 19 are both in contact with the right outer wall of the meandering plate 4. Long shafts 49 are rotatably connected to the top and bottom of the meandering plate 4. Dedicated buckles 5 are fixedly connected to the outer walls of the long shafts 49. There are a total of four dedicated buckles 5. Each dedicated buckle 5 and the adjacent part of the meandering plate 4 sleeve the same sodium battery body 19. Support blocks 6 are fixedly connected to the top and bottom of the meandering plate 4. Two spaced-apart round rods 7 are fixedly connected to the top of the support block 6. One end of the dedicated buckle 5 is fixedly connected with a rectangular block 8. Both of the two round rods 7 can be clamped inside the rectangular block 8. A plurality of groups of rubber parts are fixedly connected to the outer wall of the meandering plate 4. Each group of rubber parts includes two trapezoidal rubber blocks 12 that are far away from each other and symmetrically distributed. The two adjacent trapezoidal rubber blocks 12 in the same group of rubber parts are both movably connected to the outer wall of one of the sodium battery bodies 19. Two spaced-apart semi-circular blocks 18 are fixedly connected to the sides of the first side plate 2 and the second side plate 3 close to the meandering plate 4. The outer walls of the semi-circular blocks 18 are respectively movably connected to the outer walls of the sodium battery bodies 19. An arc-shaped groove 9 is provided on the arc-shaped outer wall of the dedicated buckle 5. Stable grooves are provided at both ends of the inner wall of the arc-shaped groove 9. A sliding rod 11 is slidably connected inside the stable groove. An arc-shaped groove 10 is fixedly connected to one end of the outer wall of the sliding rod 11. The outer wall of the arc-shaped groove 10 is slidably connected to the arc-shaped groove 9. One end of two of the arc-shaped grooves 10 is fixedly connected to the first side plate 2, and one end of the other two arc-shaped grooves 10 is fixedly connected to the second side plate 3. As can be seen from the Figure 2 and 4 the description, there is a meandering plate 4 separating two adjacent sodium battery bodies 19. When each dedicated buckle 5 is installed, it will be clamped on the sodium battery body 19 at the corresponding position. At this time, both of the two adjacent round rods 7 are clamped on the rectangular block 8, playing a role in fixing the rectangular block 8. The setting of the support block 6 enhances the stability of the round rod 7, thereby improving the fixing effect. The state of the sodium battery body 19 after installation is that half of the outer wall is in contact with the inner wall of the meandering plate 4, and the other half is in a clamped state with the upper and lower dedicated buckles 5. When the first side plate 2 and the second side plate 3 are mutually attached, that is, as described in the Figure 1At this state, each semi - moon block 18 will come into contact with each sodium battery body 19 again. The sodium battery bodies 19 are located between the upper and lower special buckles 5, and each group of rubber parts also clamps the outer walls of the sodium battery bodies 19 to prevent them from falling off. Through the arranged arc - shaped grooves two 10 and sliding rods 11, when the side plate one 2 and the side plate two 3 move away from each other, the sliding rod 11 will always slide along the inner wall of the stable groove in the arc - shaped groove one 9 and drive the special buckle 5 together. It will rotate around the axis of the corresponding long axis 49, thereby enabling the special buckle 5 to disengage from the clamping relationship with the sodium battery body 19, and the round rod 7 to disengage from the clamping relationship with the rectangular block 8. The settings of the special buckle 5 and the trapezoidal rubber block 12 improve the protection performance of the sodium battery body 19 again, reduce the possibility of its shaking, and ensure safety.

A plurality of equally - spaced electromagnetic devices 15 are fixedly connected to the inside of the side plate one 2. The electromagnetic devices 15 are located close to the clamping strips 14. One end of the inner wall of the clamping groove 16 is fixedly connected to a spring two 51. One end of the spring two 51 is fixedly connected to a sliding block 52. The sliding block 52 is slidably connected to the inside of the clamping groove 16. The sliding block 52 is movably connected to the clamping strip 14. By default, the electromagnetic device 15 is in an activated state and has magnetism. Because the side plate one 2 and the side plate two 3 are in contact with each other, that is, the magnet 17 abuts against the side plate one 2 and is close to the electromagnetic device 15, the electromagnetic device 15 generates an attractive force on the magnet 17. At this time, the clamping strip 14 is completely located inside the clamping groove 16 and presses against the sliding block 52, making the spring two 51 in a compressed state. When the sodium battery body 19 needs to be removed and the limiting handle 50 is adjusted to the horizontal position, at this time, the electromagnetic device 15 needs to be powered off, then it loses the attraction to the magnet 17. The external force on the spring two 51 suddenly disappears, and it gradually recovers its deformation to push the sliding block 52 to a position close to the magnet 17. The clamping strip 14 moves synchronously, causing the side plate one 2 to slide on the top plate 20 and increasing the distance between it and the side plate two 3. Through the above settings, the force required for manually pulling the side plate one 2 and the side plate two 3 is reduced, that is, the labor intensity is reduced, and the efficiency of removing the sodium battery body 19 is improved.

[0040] An operation method of a special shock - absorbing device for cylindrical sodium - ion batteries includes the following steps:

[0041] Step 1: Slightly and forcefully snap each sodium battery body 19 onto each supporting member 53. When the winding plate 4 comes into contact with the sodium battery body 19 simultaneously, the supporting member 53 will act on the buffer mechanism and cause its structure to change. The supporting member 53 can return to its original position under the action of the buffer mechanism within a short time. Step 2: Drive each handle to reduce the distance between the first side plate 2 and the second side plate 3 to the minimum value, that is, the state where the first side plate 2 and the second side plate 3 are in contact with each other. Then, each semi-circular block 18 and the special buckle 5 will come into contact with the outer wall of each sodium battery body 19 and clamp it. Step 3: Immediately following Step 2, activate each electromagnetic device 15 to overcome the elastic force of the second spring 51, so that the first side plate 2 and the second side plate 3 are stably combined together. After that, rotate the two limiting handles 50 to the vertical state to complete the operation steps.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
