Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery capacity division, in particular to a layer plate assembly and a restraint tray. Background Art

[0002] At present, with the introduction of the concept of carbon neutrality, as a form of new energy, lithium-ion batteries have the advantages of high energy density, long cycle life, and green and pollution-free. They have been widely used in electric vehicle power cells, energy storage and other fields.

[0003] During the charge and discharge process, the electrode near the casing of the battery cell is in a state of free deformation, resulting in interface wrinkling. Constrained capacity separation can solve interface problems such as wrinkling caused by electrode expansion during charge and discharge. The difference between conventional capacity separation and constrained capacity separation lies in whether the battery cell is restrained during charge and discharge. The restraint tray is designed to ensure that the battery cell is restrained during charge and discharge.

Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0059] The following combination Figures 1 to 16 , describing the embodiments of the present utility model.

[0060] According to an embodiment of the present invention, on the one hand, a layer plate assembly is provided, which has a first direction, a second direction and a third direction intersecting each other. Figure 1 As shown, the laminate assembly includes:

[0061] The end plate 10 includes a first plate portion 11 and second plate portions 12 disposed on both sides of the first plate portion 11 in a first direction;

[0062] A boss member 20 is provided on at least one side of the first plate portion 11 along the second direction. The boss member 20 is engaged with both the first plate portion 11 and the second plate portion 12. The boss member 20 is used to limit the battery cell in the second direction. Two limiting bosses 21 are provided on a side of the boss member 20 away from the first plate portion 11. The two limiting bosses 21 are spaced apart along the first direction. The limiting bosses 21 are used to limit the battery cell in the first direction.

[0063] The bottom support member 30 is provided on one side of the end plate 10 in the third direction. The bottom support member 30 is engaged with both the end plate 10 and the boss member 20 . The bottom support member 30 is used to limit the battery cell in the third direction.

Therefore, within the compatible range of the restraint tray, when the size of the battery cell changes, it is only necessary to replace the boss 20 and / or the bottom support 30 according to the thickness, height and / or width of the battery cell. Compared with the structural method of the related art that requires replacing the entire layer plate and the restraint block, the layer plate assembly provided by the present invention is faster, simpler and more efficient, and also greatly reduces costs. It is understandable that the end plate 10 can adopt different materials according to different restraint force design requirements, which will not be elaborated here.

[0065] The layer plate assembly provided by the present invention mainly includes an end plate 10, a boss part 20 and a bottom support part 30. The layer plate assembly adopts a split design. The end plate 10, the boss part 20 and the bottom support part 30 are independently arranged in pairs. The boss part 20 is clamped with the first plate body part 11 and the second plate body part 12, and the bottom support part 30 is clamped with the end plate 10 and the boss part 20, thereby realizing a detachable connection between the end plate 10, the boss part 20 and the bottom support part 30, which is convenient for replacing the end plate 10, the boss part 20 and / or the bottom support part 30; when the size of the battery cell changes, it is only necessary to replace the boss part 20 and / or the bottom support part 30 according to the thickness, height and / or width of the battery cell. The replacement is faster, simpler and more efficient, avoiding major modifications to the restraint tray structure, and improving the compatibility of the restraint tray with battery cells of different sizes.

[0066] Furthermore, the boss member 20 and the limiting boss 21 are an integrally formed structure.

[0067] In some embodiments, see Figure 6 and Figure 7 As shown, the first plate portion 11 is provided with a first slot 13 on at least one side thereof along the second direction; see Figure 9 and Figure 10 As shown, the boss 20 is provided with a first clamping platform 22 on one side of the first plate portion 11 along the second direction. Figure 5 As shown, the first clamping platform 22 is clamped with the first clamping groove 13 , and the first clamping platform 22 and the first clamping groove 13 are used to fix the boss member 20 and the first plate portion 11 along the first direction and the second direction.

[0068] In this embodiment, the first clamping platform 22 is clamped with the first clamping slot 13 to achieve a detachable connection between the boss part 20 and the first plate body 11, which facilitates the rapid replacement of the boss part 20 according to the thickness and / or width dimensions of different battery cells, thereby making the replacement of the restraint tray faster, simpler and more efficient.

[0069] In some embodiments, see Figure 6 and Figure 7 As shown, the first slot 13 includes a first stepped slot 131 and a second stepped slot 132 , and the first stepped slot 131 and the second stepped slot 132 are arranged at an angle;

[0070] See Figure 9 and Figure 10 As shown, the first clamping platform 22 includes a first clamping portion 221 and a second clamping portion 222 , and the first clamping portion 221 and the second clamping portion 222 are arranged at an angle;

[0071] Please combine Figure 5 As shown, the first clamping portion 221 is clamped with the first stepped groove 131, and the first clamping portion 221 and the first stepped groove 131 are used to fix the boss 20 and the first plate body 11 along the first direction; the second clamping portion 222 is clamped with the second stepped groove 132, and the second clamping portion 222 and the second stepped groove 132 are used to fix the boss 20 and the first plate body 11 along the second direction.

[0072] In this embodiment, the first clamping portion 221 and the second clamping portion 222 are arranged at an angle. The first clamping portion 221 is clamped in the first step groove 131, and the second clamping portion 222 is clamped in the second step groove 132. This can realize the detachable connection between the boss 20 and the first plate body 11, facilitate the rapid replacement of the boss 20 according to different battery cell sizes, and at the same time avoid the boss 20 from being offset relative to the first plate body 11 along the first direction and / or the second direction, thereby ensuring the reliability of the layer assembly structure.

[0073] In some embodiments, see Figure 6 and Figure 7 As shown, a second clamping platform 14 is provided on one side of the second plate portion 12 facing the first plate portion 11 along the first direction. The second clamping platform 14 and the first plate portion 11 are spaced relative to each other along the second direction and form a second clamping slot 15.

[0074] See Figure 9 and Figure 10 As shown, the third clamping platform 23 is formed on both sides of the first direction of the boss 20. Please combine it with Figure 5 As shown, the third clamping platform 23 is clamped with the second clamping groove 15 , and the third clamping platform 23 and the second clamping groove 15 are used to fix the boss member 20 and the first plate portion 11 along the first direction and the second direction.

[0075] In this embodiment, the first clamping platform 22 is clamped with the first clamping groove 13, and the third clamping platform 23 is clamped with the second clamping groove 15. At the same time, the detachable connection between the boss part 20 and the end plate 10 is realized, the connection strength between the boss part 20 and the end plate 10 is enhanced, the stability and reliability of the connection between the boss part 20 and the end plate 10 are improved, and the boss part 20 is effectively prevented from being offset relative to the end plate 10 along the first direction and / or the second direction.

[0076] See Figure 5 As shown, during the replacement installation process, it is only necessary to connect the boss part 20 with the end plate 10 along the third direction, so that the first clamping platform 22 is inserted into the first clamping groove 13 along the third direction, and the third clamping platform 23 is inserted into the second clamping groove 15, thereby completing the assembly of the boss part 20 and the end plate 10.

[0077] In some embodiments, see Figure 1 As shown, the bottom support member 30 includes a third plate portion 31 and a fourth plate portion 32 provided on at least one side of the third plate portion 31 along the second direction. Figure 5 As shown, the third plate portion 31 and the fourth plate portion 32 together enclose a bracket 33, and the first plate portion 11 and the boss member 20 are both snapped into the bracket 33;

[0078] Please combine Figure 3 As shown, one side of the limiting boss 21 in the third direction abuts against the fourth plate portion 32 .

[0079] In this embodiment, by clamping the first plate body 11 and the boss member 20 in the bracket 33, a detachable connection between the end plate 10 and the boss member 20 and the bottom support member 30 is achieved, so that the boss member 20 and / or the bottom support member 30 can be replaced according to the thickness, height and / or width of the battery cell, and the replacement is faster, simpler and more efficient; by abutting the third side of the limiting boss 21 with the fourth plate body 32, the third plate body 31 and the fourth plate body 32 are subjected to force together, thereby ensuring the structural stability of the bottom support member 30.

[0080] In some embodiments, see Figure 1 As shown, the boss member 20 is further provided with a fourth clamping platform 24, which is provided on one side of the third clamping platform 23 close to the bottom supporting member 30 along the third direction;

[0081] See Figure 8 As shown, a step portion 121 is formed on one side of the third direction of the second plate portion 12. Please combine Figure 1 、 Figure 4 and Figure 13 As shown, the step portion 121 is used to abut against the fourth clamping platform 24 along the third direction.

[0082] It should be noted that, please combine Figure 15 As shown, when changing the tray (the restraint tray is replaced with the injection molding tray), in order to facilitate the robot gripper to grab the battery cell 60 in the restraint tray, it is necessary to pre-eject the battery cell 60 in the restraint tray to a certain height along the third direction through the lifting rod. In order to prevent the lifting rod from being dislocated and ejecting the boss part 20, the layer plate assembly is designed to be fool-proof: by arranging a fourth clamping platform 24 on the boss part 20, and forming a step portion 121 on the third direction side of the second plate body 12, the step portion 121 is abutted against the fourth clamping platform 24 along the third direction, thereby limiting the boss part 20 along the third direction, and preventing the lifting rod from ejecting the boss part 20.

[0083] Please combine Figure 1 and Figure 5 As shown, during the assembly process of the layer assembly, the end of the boss part 20 away from the fourth clamping platform 24 along the third direction is plugged into the end plate 10, so that the first clamping platform 22 is inserted into the first clamping groove 13 along the third direction, and at the same time, the third clamping platform 23 is inserted into the second clamping groove 15 along the third direction, until the fourth clamping platform 24 abuts against the step portion 121 along the third direction, thereby completing the assembly of the boss part 20 and the end plate 10, and then the bottom support part 30 is clamped with the end plate 10 and the boss part 20 at the same time, thereby completing the assembly of the layer assembly.

[0084] In some embodiments, please combine Figure 1 and Figure 4 As shown, fifth clamping platforms 311 are provided on both sides of the third plate portion 31 in the first direction, and the fifth clamping platforms 311 are used to abut against the first plate portion 11 along the third direction.

[0085] In this embodiment, the fifth clamping platform 311 abuts against the first plate portion 11 along the third direction, so that the fifth clamping platform 311 and the third plate portion 31 can jointly support the end plate 10 and the boss member 20, thereby ensuring the stability of the overall structure of the bottom support member 30.

[0086] Furthermore, the third plate portion 31 , the fourth plate portion 32 and the fifth clamping platform 311 are an integrally formed structure.

[0087] According to the embodiment of the present invention, on the other hand, see Figure 15 As shown, a restraint tray is also provided, comprising: a restraint block 40, and the layer plate assembly as described above, wherein the restraint block 40 is detachably connected to the layer plate assembly.

[0088] The restraint tray provided by the present invention adopts the above-mentioned layer plate assembly. When the size of the battery cell changes, it is only necessary to replace the boss part 20 and / or the bottom support part 30 according to the thickness, height and / or width of the battery cell. The replacement is faster, simpler and more efficient, avoiding major modifications to the restraint tray structure, improving the compatibility of the restraint tray with battery cells of different sizes, and meeting the requirements of rapid replacement of the restraint tray used in the restraint capacity division process of lithium batteries within the compatible range.

[0089] In some embodiments, see Figure 15 As shown, the restraint blocks 40 are arranged on both sides of the first direction of the end plate 10. Figure 16 As shown, the restraint block 40 forms a third slot 41 on one side thereof facing the layer assembly along the first direction, and the third slot 41 is used for being engaged with the second plate portion 12 .

[0090] In this embodiment, by snapping the second plate portion 12 into the third slot 41 , the layer assembly and the restraint block 40 can be relatively fixed in the second direction, while avoiding interference between the restraint block 40 and the boss 20 .

[0091] In some embodiments, see Figure 14 As shown, the restraint block 40 is provided with a mounting hole 42 along the second direction; the restraint tray further includes a reinforcement member 50 , which is embedded in the mounting hole 42 .

[0092] In this embodiment, a reinforcement member 50 is embedded in the restraint block 40 to enhance the structural strength of the restraint block 40, thereby ensuring that the restraint block 40 is not crushed, improving the overall stress condition of the restraint tray, and also preventing the risk of the battery cell 60 being squeezed and bursting and catching fire due to overpressure in the restraint stroke.

[0093] Furthermore, the reinforcement 50 may be made of a steel rod, which can increase the restraining force bearing capacity of the restraining block 40 to 2 to 4 times the original value, thereby ensuring that the restraining block 40 is not crushed.

[0094] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
