Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery core clamping device. Background Art

[0002] With the development of the new energy industry, the energy density of battery packs has gradually increased. The use of multiple cells directly integrated into a battery pack (Cell to Pack, CTP) technology is the future development direction of the industry. CTP technology simplifies the manufacturing process of cell-module-whole pack to cell-whole pack, eliminating the intermediate process of the module, which can greatly reduce the weight of the whole pack and thus improve the energy density.

[0003] In the CTP structure, one of the methods of the battery cell boxing process is to stack and squeeze the battery cells in advance and then put them into the box together, releasing the squeezing force to make the thickness of the battery cell group rebound to fix the battery cell group. In the related art, a clamping tool is used to clamp the battery cell group. However, after the above-mentioned clamping tool clamps and fixes the battery cell group, it is impossible to directly transfer the clamped battery cell group into the battery box by using external components, thereby increasing the clamping operation process and reducing the clamping efficiency of the battery cell group.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 5 As shown, an embodiment of the utility model provides a battery cell clamping device for clamping a plurality of battery cells and moving the plurality of battery cells into a battery box, the battery cell clamping device comprising: a receiving assembly 10, having a first end face 11 and a second end face 12 arranged opposite to each other along a first direction; a clamping assembly 20, comprising clamping portions 21 respectively located on both sides of the receiving assembly 10 along a second direction, the clamping portions 21 at least partially protruding from the second end face 12 in a direction from the first end face 11 toward the second end face 12, and the clamping portions 21 located on both sides of the receiving assembly 10 and the second end face 12 A clamping space is formed between the receiving component 10 to clamp and fix multiple battery cells, and the first direction is perpendicular to the second direction; a driving component 30 is arranged on the receiving component 10, and the driving end of the driving component 30 is drivingly connected to the clamping parts 21 located on both sides of the receiving component 10 to drive the clamping parts 21 located on both sides of the receiving component 10 to move toward or in the opposite direction along the second direction; wherein, when the clamping component 20 is in a clamping state, the total length of the clamping parts 21 located on both sides of the receiving component 10 and the multiple battery cells in the second direction is less than the length of the inner wall of the battery box in the second direction.

[0031] By applying the technical solution of the utility model, clamping parts 21 are respectively provided on both sides of the receiving component 10 along the second direction, and the clamping parts 21 located on both sides of the receiving component 10 can move along the second direction. Through the above structure, multiple battery cells are clamped and fixed along the second direction, so that only two sides of the multiple battery cells are clamped, which simplifies the clamping steps and the clamping operation process, thereby improving the clamping efficiency of multiple battery cells, and when the clamping component 20 is in the clamping state, the total length of the clamping parts 21 located on both sides of the receiving component 10 and the multiple battery cells in the second direction is less than the length of the inner wall of the battery box in the second direction, so that after clamping the multiple battery cells, it is convenient to transfer the multiple battery cells into the battery box, thereby improving the installation efficiency of the multiple battery cells.

[0032] In this embodiment, X is the first direction, Y is the second direction, and Z is the third direction.

[0033] Furthermore, the receiving assembly 10 includes a first receiving member 13 and a second receiving member 14 arranged in sequence from top to bottom along the first direction, the first receiving member 13 has a first end face 11, the second receiving member 14 has a second end face 12, the driving assembly 30 is arranged on the first end face 11, the poles of the plurality of cells are arranged toward the second end face 12, and at least the second end face 12 includes an insulating material. By providing the above structure, the risk of short circuit caused by the contact between the pole and the second end face 12 during the clamping process can be prevented, thereby improving the safety during the clamping process.

[0034] Among them, in the present application, the second receiving member 14 is made of insulating material, and the insulating material may include rubber, resin, etc. The above structure is simple and has low processing difficulty, which can not only improve the processing efficiency of the structure, but also reduce the processing efficiency of the structure, which is conducive to the mass production of the second receiving member 14. No specific restrictions are made here.

[0035] At the same time, the first receiving member 13 can be made of metal material. Since metal material has high strength and toughness, can bear large loads, and resist the influence of external forces to a certain extent, the first receiving member 13 made of metal material can have excellent mechanical properties and reliability, and can maintain stable performance in various complex working environments. In addition, metal material has good plasticity and ductility, and can be easily pressed into various shapes, which enables metal material to flexibly adapt to the design requirements of the first receiving member 13 of different shapes to meet the use requirements of the device in different environments. Moreover, metal material usually has good corrosion resistance, which can improve the service life of the first receiving member 13.

[0036] Specifically, the receiving assembly 10 further includes a limiter 15, which is protruding from the second end face 12 along the first direction, and the limiter 15 extends along the second direction and is arranged on the second end face 12 at intervals along the third direction. The limiters 15 located on both sides of the second end face 12 cooperate with each other to limit the plurality of cells in the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. By setting the above structure, the cell being clamped can be limited to prevent the cell from being displaced during the clamping process, thereby ensuring the stability of the clamping.

[0037] Furthermore, the limiting member 15 includes a first connecting section 151 and a second connecting section 152 which are connected in sequence and arranged at an angle, the first connecting section 151 is connected to the second end face 12, the second connecting section 152 is arranged to protrude from the second end face 12 along the first direction, and a step structure for accommodating the pole of the battery cell is formed between the first connecting section 151 and the second end face 12. With such an arrangement, after the clamping assembly 20 clamps the battery cell, since the pole of the battery cell is usually arranged to protrude from the surface of the battery cell, a certain space can be reserved for the pole of the battery cell through the step structure to prevent the pole of the battery cell from contacting with the second end face 12 during the clamping process, thereby preventing the pole of the battery cell from being damaged, thereby ensuring the safety of the pole of the battery cell during clamping.

[0038] Specifically, the clamping portion 21 includes a clamping plate 22. The clamping plates 22 located on both sides of the receiving assembly 10 are arranged parallel to each other, and the extension length of the clamping plate 22 along the third direction is greater than or equal to the extension length of the battery cell along the third direction. By setting the above structure, the contact area between the clamping plate 22 and the side wall of the battery cell can be guaranteed, which is conducive to improving the clamping effect of the clamping plate 22 on the battery cell, thereby improving the clamping stability of the clamping assembly 20. Of course, in the present application, the length of the clamping plate 22 cannot be greater than the length of the inner wall of the battery box along the third direction, so that it can be ensured that the clamping plate 22 at least partially enters the battery box.

[0039] Furthermore, the battery cell clamping device further includes a buffer 40, and the buffers 40 are respectively arranged on the opposite side walls of the two clamping plates 22. In the present application, the buffer 40 is specifically a soft rubber, which can not only increase the friction between the clamping plate 22 and the battery cell and improve the clamping effect, but also prevent the clamping plate 22 from damaging the side wall of the battery cell, thereby protecting the structure of the battery cell.

[0040] Optionally, in other embodiments of the present application, the buffer member 40 may also be configured as other structures such as a silicone sheet, as long as the use requirements of the battery cell clamping device can be met.

[0041] Specifically, when the clamping assembly 20 is in the clamping state, the extension length of the contact area between the battery cell and the clamping part 21 along the first direction is L1, and the extension length of the battery cell along the first direction is L2, 1 / 3L2≤L1≤1 / 2L2. When L1>1 / 2L2, the extension length of the contact area between the battery cell and the clamping part 21 along the first direction is too large, which will cause the contact area between the battery cell and the clamping part 21 to occupy too much space. When the battery cell is placed in the battery box, it is not conducive to loosening the clamping part 21 and pulling it out of the battery box. When L1<1 / 3L2, the extension length of the contact area between the battery cell and the clamping part 21 along the first direction is too small, which will make the cross-sectional area of ​​the contact area between the battery cell and the clamping part 21 smaller, resulting in poor clamping effect of the clamping part 21 and reduced stability when the battery cell and the clamping part 21 are in contact. Therefore, setting 1 / 3L2≤L1≤1 / 2L2 is not only conducive to pulling out the clamping part 21 from the battery box after loosening, but also can ensure that the cross-sectional area of ​​the contact area between the battery cell and the clamping part 21 is larger, improve the clamping effect of the clamping part 21, and ensure the stability of the battery cell when in contact with the clamping part 21. Optionally, L1 can be set to a value such as 1 / 3L2, 2 / 5L2 or 1 / 2L2, and the specific setting should be selected according to the use environment of the clamping part 21, and no specific limitation is made here.

[0042] In the present application, the length of the clamping portion 21 protruding from the first end face 11 to the second end face 12 is L2, and 39.5mm≤L2≤59.25mm. When L1>59.25, the length of the clamping portion 21 protruding from the first end face 11 to the second end face 12 is too large, which will cause the clamping portion 21 to occupy too much space. In the process of placing the battery cell into the battery box, the bottom of the clamping portion is likely to interfere with the bottom of the box, thereby reducing the efficiency of placing the battery cell into the box. When L1<39.5mm, the length of the clamping portion 21 protruding from the second end face 12 from the first end face 11 to the second end face 12 is too small, which will make the cross-sectional area of ​​the contact area between the battery cell and the clamping portion 21 smaller, resulting in poor clamping effect of the clamping portion 21 and reduced stability when the battery cell contacts the clamping portion 21. Therefore, setting 39.5mm≤L2≤59.25mm is not only conducive to the efficiency of placing the battery cell into the box, but also can ensure that the cross-sectional area of ​​the contact area between the battery cell and the clamping part 21 is larger, improve the clamping effect of the clamping part 21, and ensure the stability of the battery cell when in contact with the clamping part 21. Optionally, L1 can be set to a value such as 39.5mm, 50mm or 59.25mm. The specific setting should be selected according to the use environment of the clamping part 21, and no specific limitation is made here.

[0043] Further, the driving assembly 30 includes a driving cylinder, which includes: a cylinder body 31, which is arranged on the first end surface 11; a piston rod 32, one end of the piston rod 32 is connected to the cylinder body 31, and the piston rod 32 can move relative to the cylinder body 31 along the second direction, and the other end of the piston rod 32 is connected to the clamping part 21 to drive the clamping part 21 to move. In the present application, the cylinder body 31 is specifically a driving cylinder, and the above structure is simple, which can not only meet the driving requirements of the device, but also reduce the production cost of the driving assembly 30, which is conducive to realizing the mass production of the driving assembly 30.

[0044] Specifically, the battery cell clamping device further includes a handle 50, which is disposed on the first end surface 11. The battery cell clamping device is connected to an external component via the handle 50, so that the external component moves the clamped multiple battery cells into the battery box. By providing the above structure, it is convenient for the clamping component 20 to move the battery cells after clamping the battery cells, thereby improving the efficiency of the battery cell clamping device in transferring the battery cells.

[0045] In the present application, the handle 50 includes a handle. Optionally, the handle 50 can also be configured as a structure such as a hanging ring or a hanging hole, and the specific configuration should be selected according to the use environment of the battery cell clamping device.

[0046] By applying the technical solution of the utility model, clamping parts 21 are respectively provided on both sides of the receiving component 10 along the second direction, and the clamping parts 21 located on both sides of the receiving component 10 can move along the second direction. Through the above structure, multiple battery cells are clamped and fixed along the second direction, so that only two sides of the multiple battery cells are clamped, which simplifies the clamping steps and the clamping operation process, thereby improving the clamping efficiency of multiple battery cells, and when the clamping component 20 is in the clamping state, the total length of the clamping parts 21 located on both sides of the receiving component 10 and the multiple battery cells in the second direction is less than the length of the inner wall of the battery box in the second direction, so that after clamping the multiple battery cells, it is convenient to transfer the multiple battery cells into the battery box, thereby improving the installation efficiency of the multiple battery cells.
