Description

Technical Field

[0001] The following disclosure relates to a battery module housing having an anti-slip guide structure to prevent a product or a fixture thereof from being deformed when welding cell leads during a battery module assembly process. Background Art

[0002] Typically, during the battery module assembly process, each cell lead protruding from either end of the cell and a bus bar that electrically connects the cell leads to each other can be connected to each other by laser welding. Here, the bus bar can be a structure provided on the surface of a sensing assembly (or SNSG ASSY), which is provided adjacent to the cell leads provided in the battery module housing, and the bus bar can face the housing. In addition, during the manufacture and assembly of the battery module, by laser welding between the cell leads and the sensing assembly, a pressing fixture (or a pusher) can press the sensing assembly in the direction in which the cell leads engage the bus bar, so that the bus bar and the cell leads are in close contact with each other, and then welding can be performed.

[0003] In the conventional structure, the bus bar can be welded using a counter bar, which is a structure that supports the rear surface of the sensing component (or the counter surface of the bus bar). The process can be performed in such a way that a specific space is fixed by inserting a counter bar between the cell lead and the bus bar, a pressing fixture enters using a counter bar inserted into the specific space, and then when the pressing fixture presses the cell lead, the cell lead and the bus bar are brought into close contact with each other, while the counter bar is subjected to a pressing force, and then welding is performed. Therefore, the manufacturing process can be easily performed by maintaining an appropriate pressing force between the bus bar and the cell lead through the counter bar, and ensuring the space required for welding.

[0004] However, generally, a specific space into which the relative rod can be inserted may exist between the cell lead and the relative rod, and the clamp may preferably enter toward the relative rod in a direction parallel to the cell lead. Therefore, the clamp may enter toward the relative rod in the direction of the upper end or the lower end of the bus bar. However, it is impossible for the clamp to enter the space in the direction of the upper end of the bus bar because interference occurs when the wing folded portion of the battery cell is formed in the space. Therefore, the clamp can generally enter the space only in the direction of the lower end of the bus bar. That is, the clamp can generally enter from the lower part of the battery module toward the relative rod to be inserted between the cell lead and the battery cell. However, the relative rod may only support a portion of the lower part of the battery cell. In addition, the relative rod may be inserted into the space between the battery and the lower end of the bus bar, and then the pressing clamp may enter and press the bus bar toward the battery cell so that the cell lead is in close contact with the bus bar surface, and then the bus bar and the cell lead may be welded to each other.

[0005] Here, in the conventional structure, the relative rod can enter only from the lower end. Therefore, when the pressing fixture (or pusher) enters and presses, since there is no fixture structure to support the upper part compared to the lower part, the bus bar and the relative rod may be slid upward by the relative rod, which causes asymmetry in the vertical direction. In addition, this asymmetry of the upper and lower spaces between the bus bar and the cell lead may lead to poor welding quality and unstable dispersion, as well as damage to the battery cell when its product and the relative rod slide backward; when welding is performed after sliding, residual stress may occur in the welding area, which may lead to poor durability; when the relative rod is used repeatedly, continuous force is applied, causing deformation and damage to the product. As a result, costs increase due to shorter life and shorter fixture replacement cycles. Utility Model Content

Before that, the terms and words used in the present disclosure should not be interpreted as general or dictionary meanings, but should be interpreted as meanings and concepts that conform to the technical spirit of the present disclosure, which is based on the principle that the inventor can appropriately define the concept of the term in order to describe its practical novelty in the best way.

[0030] Therefore, the configurations described in the embodiments and drawings of the present disclosure do not represent all the technical spirits of the present disclosure, but are only the most preferred embodiments. Therefore, the present disclosure should be interpreted as including all changes and substitutions included in the spirit and scope of the present disclosure when the present application is submitted.

[0031] Hereinafter, the technical spirit of the present disclosure will be described in more detail with reference to the accompanying drawings. The accompanying drawings are merely examples shown to describe the technical idea of ​​the present disclosure in more detail. Therefore, the technical idea of ​​the present disclosure is not limited to the form of the accompanying drawings.

[0032] The present disclosure relates to a housing of a battery module 10, wherein the housing having an anti-skid guide structure can prevent deformation of a product and a jig during laser welding between a cell lead and a bus bar 140 when manufacturing the battery module 10. The present disclosure may include a housing structure for preventing damage to the battery cell during the pressing process while maintaining a certain distance between the product and the jig, since the jig firmly supports the product during the pressing process of the cell lead from the bus bar 140 when the cell lead and the bus bar 140 are welded to each other. The present disclosure can ensure improved quality and stable distribution of laser welding between the cell lead and the bus bar 140 through the anti-skid guide structure, and minimize deformation of the jig used in the process, thereby ensuring its processing capability.

[0033] Therefore, when referring to Figure 1 When describing, in the shell of the battery module 10 according to the present disclosure, the shell may include: an upper shell 11, a lower shell 12, a front shell 13 and a rear shell 14, the upper shell 11, the lower shell 12, the front shell 13 and the rear shell 14 are respectively arranged on the upper surface, the lower surface, the front surface and the rear surface of the plurality of battery cells along the periphery of the plurality of battery cells, and the plurality of battery cells are in surface contact with each other and arranged in one direction; a pair of side shells 15, each side shell is arranged to be adjacent to and surround a cell lead protruding from either end in the length direction of the battery cell 1; and a sensing bus bar assembly 100, the sensing bus bar assembly 100 is arranged between the side shells 15 and the cell leads, and connects the plurality of cell leads to each other, wherein the sensing bus bar assembly 100 includes a clamp hole 110, and a clamp for supporting the sensing bus bar assembly 100 is inserted into the clamp hole 110. Here, the sensing bus bar assembly 100 may have a fixed position by clamps supporting the upper and lower ends of the sensing bus bar assembly 100, may be brought into close contact with the cell lead by a pusher pressing the sensing bus bar assembly 100 toward the surface of the cell lead, and then be connected to the cell lead by laser welding performed between the sensing bus bar assembly 100 and the cell lead.

[0034] The battery module 10 may be a battery assembly in which a plurality of battery cells 1 are loaded in a manner of surface contact with each other in one direction, the plurality of battery cells 1 are electrically connected to each other, and the plurality of battery cells 1 are accommodated in a housing to protect from external impact, heat, vibration, etc. Therefore, see Figure 1, the battery module 10 of the present disclosure may preferably include a shell that protects the upper surface, lower surface, front surface and rear surface of at least a plurality of battery cells 1 along the periphery thereof. Therefore, the battery module 10 may include an upper shell 11 assembled to the upper surface of each of the plurality of battery cells 1, a lower shell 12 assembled to the lower surface of each of the plurality of battery cells 1, a front shell 13 assembled to the front surface of each of the plurality of battery cells 1, and a rear shell 14 assembled to the rear surface of each of the plurality of battery cells 1. Here, the plurality of battery cells 1 may be arranged to contact each other in a surface in one direction. Here, one end and the other end may be the front surface and the rear surface of each of the plurality of battery cells 1, and the two long ends that may accommodate the plurality of battery cells 1 may be the upper surface and the lower surface of each of the plurality of battery cells 1, respectively. That is, the front shell 13 or the rear shell 14 may be in contact with a surface disposed at each end of the battery cell 1, and the upper shell 11 or the lower shell 12 may be in contact with the edge of the battery cell 1 in the thickness direction. It may be preferred that each of the upper case 11, the lower case 12, the front case 13, and the rear case 14 has an appropriate size and shape for accommodating each surface to protect a portion of the battery cell 1 in contact therewith. Here, the front case 13 or the rear case 14 may include a wiring harness or a temperature sensor wiring board on its surface accommodating the battery cell 1.

[0035] In addition, when referring to Figure 1 When describing, the battery cell 1 may include a cell lead extending from both ends thereof in the length direction, and the housing of the present disclosure may include a pair of side housings 15 assembled to the corresponding cell leads at both ends to protect the surface of the cell leads. In addition to the upper surface, lower surface, front surface, and rear surface of each of the plurality of battery cells 1, each of the side housings 15 may be disposed on the left surface or the right surface of each of the plurality of battery cells 1. Based on the front surface of each of the plurality of battery cells 1, one side housing 15 may be assembled to the left surface, and the other side housing 15 may be assembled to the right surface. Here, the pair of side housings 15 may have the same or different shapes based on the components assembled thereto. The side housing 15 may be a housing that accommodates the cell leads and electrically connects the cell leads to each other, and may have a structure that allows electrical connection to the outside from the accommodated cell leads.

[0036] Therefore, when referring to Figure 1 When described, the present disclosure may include a sensing bus bar assembly 100 that is disposed between the side case 15 and a plurality of cell leads and connects the cell leads to the side case 15. Figures 2 to 5, the sensing bus bar assembly 100 may have one surface 101 and another surface 102, the one surface 101 being an injection surface in contact with the cell lead, and the other surface 102 being configured as a bus bar 140 in contact with the side case 15. The sensing bus bar assembly 100 may include a predetermined hole 130, through which a plurality of cell leads may pass, and the cell leads of the battery cell 1 may thus pass through the hole 130 and then perform electrical connection with each other outside the sensing bus bar assembly 100. Therefore, a plurality of cell leads may be bent toward the bus bar 140 and in contact with the bus bar 140, and the plurality of cell leads may thus be electrically connected to each other. In addition, as Figure 7 As shown, the sensing bus bar assembly 100 and the cell leads may preferably be assembled to each other in close contact with each other.

[0037] like Figure 7 As shown, according to the present disclosure, the sensing bus bar assembly 100 can be in close contact with the cell lead, and the sensing bus bar assembly 100 and the cell lead can then be connected to each other by laser welding. In addition, during laser welding, the pusher can press the sensing bus bar assembly 100 toward the cell lead to be in close contact with the cell lead, and then welding can be performed by emitting a laser onto the cell lead. Here, the present disclosure may include a fixture hole 110, into which a fixture for supporting the sensing bus bar assembly 100 is inserted. The fixture hole 110 may have a pin or hole structure and have a predetermined depth. Therefore, when the fixture is inserted into the fixture hole 110 to a certain depth, the fixture can support the sensing bus bar assembly 100. When the pusher then presses the sensing bus bar assembly 100 toward the cell lead, the fixture hole can withstand the pressing force of the sensing bus bar assembly 100 and fix its position.

[0038] When referring to Figure 2 and Figure 4When described in more detail, the sensing bus bar assembly 100 of the present disclosure may include a fixture hole 110 having a groove formed in a predetermined depth from its edge inward. The fixture hole 110 may preferably be formed in the upper end or lower end of the sensing bus bar assembly 100 by the structure of the battery module 10. In addition, the fixture hole 110 may have a depth in a direction parallel to the height of the sensing bus bar assembly 100. That is, the fixture hole 110 may have a groove having a depth formed in the vertical direction of the sensing bus bar assembly 100. Here, the fixture supporting the sensing bus bar assembly 100 may support and clamp the upper and lower ends of the sensing bus bar assembly 100 and serve as a relative rod. In particular, the fixture may have a support leg having a shape and length corresponding to the groove of the fixture hole 110, and the support leg may preferably be arranged to correspond to the number and position of the fixture hole 110. Therefore, the fixture hole 110 may be formed in the sensing bus bar assembly 100 to correspond to the number and position of the support leg. Furthermore, the depth of the clamp hole 110 may correspond to the height of the support leg, and the depth of the clamp hole 110 may preferably be smaller than the height of the support leg.

[0039] Reference Figure 2 and Figure 4 , a plurality of clamp holes 110 may be provided in the present disclosure, and at least one clamp hole 110 may be provided in each of the upper and lower ends of the sensing bus bar assembly 100. Here, the depth of the clamp hole 110 formed in the upper end of the sensing bus bar assembly 100 and the depth of the clamp hole 110 formed in the lower end of the sensing bus bar assembly 100 may be the same or different from each other, and the sizes of the clamp holes 110 may also be the same or different from each other. In addition, when a large number of clamp holes 110 are formed, the clamp holes 110 may be spaced apart from each other by a predetermined distance in a direction perpendicular to the depth direction thereof. In more detail, the clamps and the clamp holes 110 that clamp the sensing bus bar assembly 100 may correspond to each other. When a plurality of clamp holes 110 are provided in the horizontal direction and the vertical direction, respectively, the clamp holes 110 provided in the vertical direction may be provided on the same line. In more detail, when a plurality of clamp holes 110 are provided in the height direction and the width direction of the sensing bus bar assembly 100 while being spaced apart from each other by a predetermined distance, the clamp holes 110 provided in the upper and lower ends of the sensing bus bar assembly 100 may be preferably aligned in the vertical direction. When the bus bar 140, which is one surface of the sensing bus bar assembly 100, is in close contact with the cell lead, such a configuration may be provided to take into account the structure of the cell lead, and when the supporting legs of each clamp are inserted and supported on the same axis in the vertical direction, the force may be more stably distributed and the sensing bus bar assembly 100 may be fixed.

[0040] In addition, the clamp hole 110 of the present disclosure may be formed in the surface 101 of the sensing bus bar assembly 100 that contacts the battery cell 1. That is, the clamp hole 110 may be formed in one surface 101 that is an opposite surface of the bus bar 140 formed on the other surface 102 of the sensing bus bar assembly 100. Therefore, the clamp hole 110 may be formed in the surface 101 of the sensing bus bar assembly 100 that contacts the battery cell 1, and the clamp hole 110 may be provided between the sensing bus bar assembly 100 and the battery cell 1.

[0041] When reference Figure 2 and Figure 4 When described in more detail, the sensing bus bar assembly 100 may include a cell lead bonding portion 120 formed on a surface 101 in contact with the battery cell 1, the cell lead bonding portion 120 having a length in the vertical direction of the sensing bus bar assembly 100 and protruding with a predetermined thickness. When a plurality of battery cells 1 are stacked and packaged into the battery module 10, the cell lead bonding portion 120 may be used to support the battery cell 1 and fix its side surface. The cell lead bonding portion 120 may be disposed between the cell leads led out from the battery cell 1. That is, the cell lead bonding portion 120 may be formed between the holes 130 of the sensing bus bar assembly 100 through which the cell leads pass. Therefore, a plurality of cell lead bonding portions 120 may be disposed in the width direction of the sensing bus bar assembly 100, which is a direction corresponding to the direction in which the battery cells 1 are disposed. Therefore, the cell lead bonding portion 120 may have a predetermined length in the height direction of the sensing bus bar assembly 100, protrude with a predetermined thickness "D", and the cell lead bonding portions 120 may be arranged to be parallel to each other in a direction perpendicular to the length direction. Here, the length of the cell lead bonding portion 120 may be less than the height of the sensing bus bar assembly 100. The number of the cell lead bonding portions 120 may preferably be determined based on the number of battery cells 1. The width of the cell lead bonding portion 120 may correspond to the distance between the loaded battery cells 1 that are in surface contact with each other.

[0042] Here, the clamp hole 110 may protrude with a predetermined thickness “d” in a direction corresponding to a direction in which the cell lead bonding portion 120 protrudes from the sensing bus bar assembly 100. Figure 2 and Figure 4, among the plurality of unit lead bonding parts 120, the clamp hole 110 may be provided in each of the upper and lower ends of the selected unit lead bonding parts 120. That is, among the plurality of unit lead bonding parts 120, the length of each unit lead bonding part 120 is less than the length of the sensing bus bar assembly 100, and the clamp hole 110 may be provided in each of the two ends of the selected unit lead bonding part 120. Here, the selected unit lead bonding parts 120 may be alternating unit lead bonding parts 120. That is, the clamp hole 110 may be formed in each of the upper and lower ends of the unit lead bonding parts 120 that are alternately arranged with each other among the plurality of unit lead bonding parts 120 that are arranged in parallel with each other. In addition, the end of the clamp hole 110 may preferably correspond to the end of the sensing bus bar assembly 100. Therefore, in each of the two ends of the sensing bus bar assembly 100, an empty space is formed, in which all the clamp holes 110 each having a predetermined depth can be accommodated within the height of the sensing bus bar assembly 100, and the depth of the clamp holes 110 can be set in the space while being exposed to the outside. Figure 6 In order to stably couple the sensing bus bar assembly 100 to the plurality of battery cells 1 , in the sensing bus bar assembly 100 , a protruding thickness “D” of the cell lead bonding portion 120 protruding from the surface 101 of the sensing bus bar assembly 100 and a protruding thickness “d” of the clamp hole 110 may be the same as each other.

[0043] Therefore, the sensing bus bar assembly 100 according to the present disclosure can ensure a predetermined distance between the battery cell 1 and the sensing bus bar assembly 100 through the clamp hole 110, which protrudes toward the portion of the sensing bus bar assembly 100 that engages the cell lead, thereby eliminating the need for a separate opposing rod and ensuring easy operation and improved welding quality during welding while preventing poor durability due to residual stress. In addition, the clamp hole 110 can also be set in the upper end of the sensing bus bar assembly 100, which is not interfered by the cell wing folded portion appearing in the upper end of the battery module 10. Therefore, the clamp can firmly support the upper and lower ends of each sensing bus bar assembly 100, and the pusher can therefore press the battery cell 1, thereby preventing sliding of the product and the clamp. As Figure 8 As shown, the legs of each clamp can be constrained in each clamp hole 110. Thus, as shown in FIG. Fig. 9A and Fig. 9B As shown, when the pusher presses the sensing busbar assembly 100, the amount of deformation applied thereto can be reduced and the stress can be distributed. In addition, the clamp leg can support the pressing force while being directly inserted into the clamp hole 110, and thus can withstand the pressing force applied to the clamp. Therefore, the clamp deformation can be minimized, and the cost can be reduced by increasing the clamp replacement cycle.

[0044] As described above, the battery module with an anti-slip guide structure according to the present disclosure constructed as described above can use a structure for preventing its products and fixtures from being deformed when welding the cell leads of the battery module, thereby ensuring improved welding quality and stable distribution, reducing damage that may be caused to the battery cells due to sliding phenomena, improving processing accuracy and stability through the guiding shape, thereby improving processing capabilities, and also increasing the fixture replacement cycle, thereby reducing costs.

[0045] In the above, although the present disclosure has been described by specific matters such as detailed components, embodiments and drawings, these specific matters are provided only to help fully understand the present disclosure. Therefore, the present disclosure is not limited to the embodiments, and technicians in the field of the present disclosure can make various modifications and changes according to this specification.

[0046] Therefore, the spirit of the present disclosure should not be limited to these embodiments, and all modifications are intended to fall within the scope and spirit of the present disclosure.
