It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0046] In the related art, a battery module stacking tool is usually used to stack and squeeze the battery cells to eliminate the assembly gap before proceeding to the subsequent process. However, the current battery module stacking tool has low adaptability and is not compatible with the stacking of battery modules of different lengths. Therefore, the technical solution of the present application is generated. Figure 1 to Figure 4 To elaborate.

[0047] Example 1

[0048] This embodiment discloses a stacking tool for a battery module 1 , which may include a bottom plate assembly 10 , a first end plate assembly 20 , a second end plate assembly 30 and an adjustment bolt 40 .

[0049] The bottom plate assembly 10 is the installation base and bearing base of the present application. The battery module 1 can be placed on the bottom plate assembly 10. Other components of the stacking tooling can also be installed on the bottom plate assembly 10. The bottom plate assembly 10 can be provided with a plurality of adjustment screw holes 101 along its own length direction X. The battery module 1 can include a plurality of battery cells 1a arranged in series in sequence, and a module end plate 1b is provided at each end of the plurality of battery cells 1a in series. The binding band 1c is wrapped around the module end plate 1b and the plurality of battery cells 1a in series to form the battery module 1.

[0050] The first end plate assembly 20 and the second end plate assembly 30 are sequentially mounted on the bottom plate assembly 10 along the length direction X, and the battery module 1 can be placed between the first end plate assembly 20 and the second end plate assembly 30, so that the first end plate assembly 20 and the second end plate assembly 30 cooperate with each other to achieve stacking and clamping of the battery module 1. The first end plate assembly 20 is provided with a through hole 201 corresponding to the adjustment screw hole 101.

[0051] The adjusting bolt 40 is configured to pass through the through hole 201 and connect the adjusting screw hole 101, so that the first end plate assembly 20 is connected to the bottom plate assembly 10 through the adjusting bolt 40. In the stacking tool of the present application, the adjusting bolt 40 can change the connected adjusting screw hole 101, so that the first end plate assembly 20 is away from or close to the second end plate assembly 30.

[0052] As mentioned above, the stacking tooling of the present application can be adapted to battery modules 1 with different numbers of strings. For example, when the specification of the stacked battery modules 1 is increased from 16 strings to 20 strings, first, the adjustment bolt 40 in the through hole 201 needs to be separated from the current adjustment screw hole 101 so that the first end plate assembly 20 can be released from the connection relationship with the bottom plate assembly 10; then, the first end plate assembly 20 is slid along the length direction X to move away from the second end plate assembly 30; when the spacing between the first end plate assembly 20 and the second end plate assembly 30 is adjusted to accommodate a battery module 1 with a specification of 20 strings, the adjustment bolt 40 is reconnected to the corresponding adjustment screw hole 101 so that the first end plate assembly 20 is connected and fixed to the bottom plate assembly 10.

[0053] In this way, by changing the position of the threaded hole connected to the adjustment bolt 40, the spacing between the first end plate assembly 20 and the second end plate assembly 30 can be adjusted, and then different specifications of battery modules 1 can be adapted, such as 16 strings to 28 strings of battery modules 1, thereby improving the compatibility of the stacking tooling of the present application.

[0054] Optionally, the length of the bottom plate assembly 10 is 2500 mm to 2700 mm, such as 2500 mm, 2600 mm, 2700 mm, wherein the preferred length of the bottom plate assembly 10 is 2600 mm to adapt to a battery module 1 with a specification of 28 strings.

[0055] Optionally, the bottom plate assembly 10 is provided with adjustment screw holes 101 on both sides along its own width direction Y, and the first end plate assembly 20 is provided with through holes 201 on both sides along the width direction Y. Specifically, the through holes 201 can be arranged in multiple rows along the length direction X, for example, four through holes 201 are arranged in each row, and a row of through holes 201 is arranged on each side of the first end plate assembly 20 along the width direction Y. Correspondingly, multiple adjustment bolts 40 are also configured, and the multiple adjustment bolts 40 correspond one-to-one to the multiple through holes 201. In this way, the connection stability between the first end plate assembly 20 and the bottom plate assembly 10 can be improved.

[0056] Optionally, the adjustment screw hole 101 may be an M20 screw hole, and the adjustment bolt 40 may be an M20 bolt, so as to further ensure the connection stability between the first end plate assembly 20 and the bottom plate assembly 10 .

[0057] Optionally, 20 adjusting screw holes 101 are arranged in a row along the length direction X to ensure the adjustable stroke of the first end plate assembly 20 .

[0058] Optionally, the first end plate assembly 20 may include a first substrate 21, a first mounting frame 22 and a first end plate 23. The first substrate 21 is provided with a through hole 201; the first mounting frame 22 is connected to the first substrate 21 and avoids the through hole 201; the first end plate 23 is connected to the first mounting frame 22 and faces the second end plate assembly 30. The first end plate 23 and the second end plate assembly 30 cooperate with each other to achieve stacking and pressing of the battery module 1. In this way, by avoiding the through hole 201 by the first mounting frame 22, interference with the adjustment bolt 40 can be avoided. At the same time, the first substrate 21 can be thinned while ensuring the overall strength of the first end plate assembly 20, thereby reducing the length of the adjustment bolt 40.

[0059] Optionally, the first end plate assembly 20 may further include an abutment column 24, which is disposed on the side of the first end plate 23 facing the second end plate assembly 30. In this way, the abutment column 24 can participate in the abutment against the battery module 1. Compared with the manner in which the entire end surface of the first end plate 23 abuts against the battery module 1, the provision of the abutment column 24 can reduce the contact area between the first end plate assembly 20 and the battery module 1, thereby preventing the end surface of the first end plate 23 from being insufficiently flat and affecting the abutment effect against the battery module 1.

[0060] Optionally, multiple abutment columns 24 can be provided. For example, the end face of the first end plate 23 is a rectangular face, and four abutment columns 24 are provided. The four abutment columns 24 are respectively provided near the four corner positions of the end face of the first end plate 23, and are evenly abutted on the battery module 1 in a four-point abutment manner, thereby improving the contact stability with the battery module 1, and further ensuring the stability of the extrusion force applied to the battery module 1 during stacking.

[0061] Example 2

[0062] This embodiment further introduces the base plate assembly 10 based on the embodiment 1, and the details are as follows:

[0063] The bottom plate assembly 10 may include a bottom plate 11 and a bearing plate assembly 12. The first end plate assembly 20 and the second end plate assembly 30 are both mounted on the bottom plate 11, and the adjustment screw hole 101 is provided on the bottom plate 11. The bearing plate assembly 12 is provided on the bottom plate 11 and is located between the first end plate assembly 20 and the second end plate assembly 30. The width of the bearing plate assembly 12 is smaller than the width of the bottom plate 11 and smaller than the width of the battery module 1, and the width of the bottom plate 11 is larger than the width of the battery module 1.

[0064] The load-bearing plate assembly 12 is used to support the battery module 1. By setting the load-bearing plate assembly 12 narrower than the base plate 11, the flatness of the load-bearing surface of the load-bearing plate assembly 12 can be made to meet the process requirements more easily while ensuring the overall strength of the base plate assembly 10, so as to ensure sufficient contact between the load-bearing plate assembly 12 and the battery module 1, and prevent the load-bearing surface of the base plate assembly 10 from being uneven and affecting the stable placement of the battery module 1.

[0065] Optionally, the bottom plate 11 may be provided with weight-reducing holes 111 , and the weight-reducing holes 111 are arranged in a plurality of rows along the length direction X and in a plurality of rows along the width direction Y, thereby achieving weight reduction of the stacked tooling and ensuring overall lightweight.

[0066] Optionally, a baffle 13 is provided on both sides of the base plate 11 along the width direction Y, and the first end plate assembly 20 and the second end plate assembly 30 are both installed between the two baffles 13. The two baffles 13 can realize the limiting constraints on the first end plate assembly 20, the second end plate assembly 30 and the battery module 1 along the width direction Y, which facilitates the installation of the first end plate assembly 20 and the second end plate assembly 30 and prevents the battery module 1 from shaking along the width direction Y.

[0067] Optionally, the load-bearing plate assembly 12 may include a plurality of load-bearing plates 121 sequentially arranged along the length direction X, and the load-bearing plates 121 may be detachably connected to the bottom plate 11 by means of bolts or the like. For example, when the stacked battery modules 1 are reduced from 25 strings to 20 strings, the redundant load-bearing plates 121 may be removed to reduce the overall weight of the stacking tooling. In this way, the load-bearing plate assembly 12 may adaptively change the number of load-bearing plates 121 according to the change in the specifications of the battery modules 1, thereby achieving weight control of the stacking tooling.

[0068] Optionally, the supporting plate assembly 12 may further include an adjusting plate 122 , which is slidably connected to the bottom plate 11 along the length direction X, and the adjusting plate 122 and the plurality of supporting plates 121 are sequentially arranged along the length direction X.

[0069] The setting of the carrier plate assembly 12 is not only convenient for placing the battery module 1, but also convenient for the bandage 1c to bind the battery cell 1a and the module end plate 1b. Specifically, the bandage 1c can be first wrapped around the peripheral side of the carrier plate assembly 12, and then the battery cell 1a and the module end plate 1b are pre-bound and placed on the carrier plate assembly 12, and then the bandage 1c wrapped around the peripheral side of the carrier plate assembly 12 is pushed upward to wrap around the battery cell 1a and the module end plate 1b, so as to bind the battery cell 1a and the module end plate 1b with the bandage 1c. The slidable setting of the adjustment plate 122 can be fine-tuned according to the length of the bandage 1c, thereby changing the spacing between the adjustment plate 122 and the multiple carrier plates 121, so as to tighten the bandage 1c and realize that the bandage 1c is tightly clamped around the peripheral side of the carrier plate assembly 12, which is convenient for pre-fixing the bandage 1c and preventing the bandage 1c from moving.

[0070] Optionally, for the specific method in which the adjustment plate 122 is slidably connected to the base plate 11 along the length direction X, an oblong hole 1221 can be provided on the adjustment plate 122, and a screw hole corresponding to the oblong hole 1221 can be provided on the base plate 11. The adjustment plate 122 can be connected to the base plate 11 by passing a bolt through the oblong hole 1221 and connecting the screw hole of the base plate 11. By loosening the bolt appropriately, the oblong hole 1221 and the bolt can be slidably fitted together, thereby realizing the position adjustment of the adjustment plate 122 along the length direction X.

[0071] Optionally, the oblong holes 1221 can be arranged in multiple rows along the length direction X and in multiple rows along the width direction Y to ensure the connection stability between the adjustment plate 122 and the base plate 11, and to improve the guiding effect between the oblong holes 1221 and the bolts passed therethrough, thereby improving the accuracy of the movement of the adjustment plate 122 along the length direction X.

[0072] Optionally, the carrier plate assembly 12 may further include a clamping plate 123, which is connected to the bottom plate 11 and is located on the side of the plurality of carrier plates 121 away from the adjustment plate 122, and a band receiving gap 124 is formed between the clamping plate 123 and the adjacent carrier plates 121. In this way, a portion of the band 1c may be first clamped into the band receiving gap 124 for positioning, and then the band 1c may be tightly bound around the carrier plate 121 and the adjustment plate 122, and then the battery cell 1a and the module end plate 1b may be placed on the carrier plate assembly 12, and then the band 1c may be pushed upward to bind the battery cell 1a and the module end plate 1b.

[0073] It can be seen that by setting the strap accommodating gap 124, the efficiency of the strap 1c being tightly clamped on the load-bearing plate assembly 12 can be improved, thereby improving the stacking efficiency of the battery module 1 by the stacking tool of the present application.

[0074] Optionally, a side of the adjustment plate 122 facing away from the bottom plate 11 and a side of the supporting plate 121 facing away from the bottom plate 11 are both provided with an avoidance groove 1211. The avoidance groove 1211 can be set through along the length direction X and be located in the middle position of the supporting plate assembly 12. In this way, the contact area between the supporting plate assembly 12 and the battery module 1 can be further reduced, and the flatness of the supporting surface of the supporting plate assembly 12 can more easily meet the process requirements, thereby ensuring sufficient contact between the supporting plate assembly 12 and the battery module 1 and preventing the battery module 1 from being placed unstable.

[0075] Example 3

[0076] Based on the first embodiment, this embodiment further introduces the structure of the second end plate assembly 30, which is as follows:

[0077] The second end plate assembly 30 can be connected to the bottom plate assembly 10 by sliding along the length direction X. In this way, the second end plate assembly 30 and the first end plate assembly 20 can both slide along the length direction X to change the initial spacing between the second end plate assembly 30 and the first end plate assembly 20, thereby adapting to battery modules 1 of different specifications. For example, the second end plate assembly 30 can be set to the same structure as the first end plate assembly 20, and then different adjustment screw holes 101 are set through the adjustment bolt 40 to adjust the initial position of the second end plate assembly 30. The second end plate assembly 30 can also be connected to the bottom plate assembly 10 by sliding the slide rail slider to adjust the initial position of the second end plate assembly 30. In this case, the adjustment method adopted can be: the second end plate assembly 30 and the first end plate assembly 20 move simultaneously to move away from or close to each other; the adjustment method can also be: one of the second end plate assembly 30 and the first end plate assembly 20 moves, and the other is fixed to move away from or close to each other. The above adjustment methods can adjust the initial spacing between the second end plate assembly 30 and the first end plate assembly 20 to adapt to battery modules 1 of different specifications.

[0078] In the present application, the second end plate assembly 30 is fixedly connected to the bottom plate assembly 10, so that the initial spacing between the second end plate assembly 30 and the first end plate assembly 20 can be adjusted only by moving the first end plate assembly 20, thereby simplifying the operation. The specific structure of the second end plate assembly 30 is set as follows:

[0079] The second end plate assembly 30 may include a second mounting frame 31, a lead screw nut 32, a lead screw 33, and a second end plate 34. The second mounting frame 31 is fixed to the base plate assembly 10, the lead screw nut 32 is passed through the second mounting frame 31; the lead screw 33 is screw-drivenly matched with the lead screw nut 32; the second end plate 34 is connected to the lead screw 33, and is disposed facing each other along the length direction X with the first end plate assembly 20.

[0080] The lead screw 33 can drive the second end plate 34 to move so that the second end plate 34 is away from or close to the first end plate assembly 20, thereby achieving stacking of the battery modules 1, specifically in the following manner:

[0081] The initial position of the first end plate assembly 20 is adjusted until the initial spacing between the first end plate assembly 20 and the second end plate assembly 30 is adapted to the battery module 1 .

[0082] The lead screw 33 is rotated around the first circumferential direction to drive the second end plate 34 away from the first end plate assembly 20 .

[0083] The battery module 1 to be stacked is placed on the bottom plate assembly 10 and located between the first end plate assembly 20 and the second end plate assembly 30 .

[0084] The lead screw 33 is rotated around the second circumferential direction to drive the second end plate 34 to approach the first end plate assembly 20 until the battery module 1 is clamped. The first circumferential direction and the second circumferential direction are opposite.

[0085] In this way, the second end plate 34 and the first end plate assembly 20 are gradually closed and clamp the battery module 1 to eliminate the assembly gaps between the battery cells 1a and between the battery cells 1a and the module end plate 1b.

[0086] Optionally, the second end plate assembly 30 may further include a second guide rod 35 and a second guide bearing 36, the second guide bearing 36 is mounted to the second mounting frame 31, the second guide rod 35 and the second guide bearing 36 are guided in the length direction X, and the second guide rod 35 is connected to the second end plate 34. In this way, the guiding cooperation between the second guide rod 35 and the second guide bearing 36 can achieve the guiding effect on the second end plate 34 to prevent the second end plate 34 from deviating from the length direction X when moving.

[0087] Optionally, a plurality of second guide rods 35 and second guide bearings 36 may be provided in one-to-one correspondence. For example, the second guide rods 35 are provided on both sides of the second mounting frame 31 along the width direction Y to improve the guiding accuracy.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
