[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.

[0032] First, the embodiment of the present application provides a crossbeam glue filling tool, which is used for glue filling of battery packs, such as Figure 4 and Figure 5 As shown, the battery pack 10 includes a box body 200, which is formed with a accommodating cavity 210. The box body 200 serves as a protective shell of the battery pack 10, and is used to isolate the external environment from the internal structure of the battery pack 10 to ensure the stability of the internal structure of the battery pack 10. The accommodating cavity 210 formed in the box body 200 is used to place battery modules and various electrical components.

[0033] like Figure 1 and Figure 3 As shown, the crossbeam glue filling tool 100 includes a crossbeam assembly 110, which is used to be set in the box body 200. The crossbeam assembly 110 is used to divide the accommodating cavity 210 into a battery compartment 220 and an electrical compartment 230. That is, when the battery pack 10 is glued, it is necessary to first install the crossbeam glue filling tool 100 into the box body 200, so that the crossbeam assembly 110 in the crossbeam glue filling tool 100 is connected to the bottom of the box body 200, and at the same time, the accommodating cavity 210 of the box body 200 is divided into a battery compartment 220 and an electrical compartment 230. The battery compartment 220 is used to place the battery module, and the electrical compartment 230 is used to place various electrical components.

[0034] The crossbeam glue filling tool 100 includes a glue filling plate 120, which is connected to the crossbeam assembly 110. The glue filling plate 120 is used to correspond to and cover the battery compartment 220. The glue filling plate 120 is provided with glue filling holes 121 for filling glue into the battery compartment 220. That is, the glue filling plate 120 and the crossbeam assembly 110 are combined to form the crossbeam glue filling tool 100. When the crossbeam assembly 110 is connected to the bottom of the box body 200, the glue filling plate 120 automatically corresponds to and covers the battery compartment 220. Glue can be poured into the battery compartment 220 through the glue filling holes 121 on the glue filling plate 120. The crossbeam assembly 110 is arranged between the battery compartment 220 and the electrical compartment 230, which can play a good isolation role, preventing glue from overflowing from the battery compartment 220 into the electrical compartment 230 during glue filling, thereby preventing the electrical components in the electrical compartment 230 from being contaminated by the glue.

[0035] In addition, by directly combining the glue filling plate 120 with the crossbeam assembly 110, it also helps to shorten the production time of the battery pack 10 and reduce production costs; and by connecting the crossbeam assembly 110 with the bottom of the box body 200, while isolating the battery compartment 220 and the electrical compartment 230, it also helps to improve the overall structural strength of the battery pack 10.

[0036] In the embodiment of the present application, the crossbeam glue filling tool 100 includes a crossbeam assembly 110 and a glue filling plate 120. The crossbeam assembly 110 is used to be disposed in the box body 200. The crossbeam assembly 110 is used to divide the accommodating cavity 210 into a battery compartment 220 and an electrical compartment 230. The glue filling plate 120 is connected to the crossbeam assembly 110. The glue filling plate 120 is used to correspond to and cover the battery compartment 220. The glue filling plate 120 is provided with glue filling holes 121 for filling glue into the battery compartment 220. In the present application, the crossbeam assembly 110 and the glue filling plate 120 are combined to form the crossbeam glue filling tool 100. The glue filling plate 120 corresponds to the battery compartment 220 of the battery pack 10. When the battery pack 10 is being glued, the crossbeam assembly 110 can act as an isolation device to prevent glue from overflowing from the battery compartment 220 into the electrical compartment 230 during glue filling, thereby preventing the electrical components in the electrical compartment 230 from being contaminated by the glue.

[0037] Optional, such as Figure 3 and Figure 5As shown, the crossbeam assembly 110 includes a first crossbeam 111 and a second crossbeam 112 arranged opposite each other along the depth direction of the accommodating cavity 210. The first crossbeam 111 is used to connect to the bottom of the box body 200, and the second crossbeam 112 is connected to the glue filling plate 120. In other words, the crossbeam assembly 110 is composed of two crossbeams, the upper and lower parts. The first crossbeam 111 located in the lower part is directly connected to the bottom of the box body 200 and, as part of the battery pack 10, divides the accommodating cavity 210 in the box body 200 into a battery compartment 220 and an electrical compartment 230. The second crossbeam 112 located in the upper part, together with the glue filling plate 120, forms a glue filling assembly to provide isolation during glue filling.

[0038] Among them, a first through hole 113 is formed between the first crossbeam 111 and the second crossbeam 112. The first through hole 113 is used to connect the electrical compartment 230 and the battery compartment 220. The first through hole 113 can be used as a wiring harness hole for the wiring harness to pass through, that is, in addition to being used to isolate the battery compartment 220 and the electrical compartment 230, the crossbeam assembly 110 can also serve as a wiring channel for the wiring harness. That is to say, when assembling the battery pack 10, the battery compartment 220 is used to place the battery module, and various signal acquisition harnesses are arranged above the battery module. The signal acquisition harness needs to be connected to the electrical components located in the electrical compartment 230 to realize the collection of battery module signals. By forming a first through hole 113 between the first beam 111 and the second beam 112, the harness can pass directly through the middle of the beam assembly 110 without crossing over the beam assembly 110, which helps to optimize the layout of the harness in the battery pack 10. At the same time, it can also reduce the risk of glue overflow caused by the harness crossing the beam assembly 110, thereby improving the sealing between the battery compartment 220 and the electrical compartment 230.

[0039] It should be noted that since the battery modules generate a large amount of heat during operation of the battery pack 10, cooling pipes are required to be provided at corresponding locations within the battery compartment 220 to cool the battery modules. In this embodiment of the present application, the first through-hole 113 formed between the first crossbeam 111 and the second crossbeam 112 can also serve as a hole for a water supply pipe to pass through, thereby optimizing the arrangement of the water pipes within the battery pack 10, reducing the risk of glue overflow caused by the water pipe installation, and further improving the sealing between the battery compartment 220 and the electrical compartment 230.

[0040] Among them, the first through hole 113 can be arranged only on the side of the first beam 111 facing the second beam 112, or only on the side of the second beam 112 facing the first beam 111, or partially on the first beam 111 and partially on the second beam 112. The specific setting method can be selected and adjusted according to actual design requirements, and no special restrictions are made here.

[0041] In some embodiments, the crossbeam glue-filling tool 100 further includes a buffer 114, which is positioned between the first crossbeam 111 and the second crossbeam 112. A second through-hole 115 is formed on the buffer 114 at a position corresponding to the first through-hole 113. The second through-hole 115 is used to connect the electrical compartment 230 and the battery compartment 220. The buffer 114 is a structural member with a certain degree of deformability, such as a soft silicone pad. By providing the second through-hole 115 on the buffer 114, the wiring harness and water pipes can pass through the second through-hole 115 on the buffer 114. The deformability of the buffer 114 can be utilized to accommodate wiring harnesses and water pipes of different sizes, thereby further improving the sealing between the battery compartment 220 and the electrical compartment 230 and preventing glue overflow.

[0042] It should be noted that the second through hole 115 formed on the buffer member 114 is adapted to the first through hole 113 formed between the first beam 111 and the second beam 112, that is, the buffer member 114 is arranged along the two opposite sides of the first beam 111 and the second beam 112, so that the shape of the second through hole 115 is consistent with the shape of the first through hole 113.

[0043] In other embodiments, the buffer 114 includes a first sub-buffer 1141 and a second sub-buffer 1142 disposed opposite each other along the depth direction of the accommodating cavity 210. The first sub-buffer 1141 abuts the first crossbeam 111, while the second sub-buffer 1142 abuts the second crossbeam 112. A second through-hole 115 is formed between the first sub-buffer 1141 and the second sub-buffer 1142. In other words, the buffer 114 and the crossbeam assembly 110 have the same structure, both consisting of an upper and lower portion. This allows the first crossbeam 111 to be secured to the bottom of the case 200 before the first sub-buffer 1141 is positioned on the first crossbeam 111 before the wiring harness and water pipes are passed through the top of the first sub-buffer 1141. The second sub-buffer 1142 and the second crossbeam 112 are then assembled sequentially. This allows for better adaptation to wiring harnesses and water pipes of varying sizes, and improves the seal between the battery compartment 220 and the electrical compartment 230.

[0044] Similarly, the second through hole 115 can be arranged only on the side of the first sub-buffer 1141 facing the second sub-buffer 1142, or only on the side of the second sub-buffer 1142 facing the first sub-buffer 1141, or partially on the first sub-buffer 1141 and partially on the second sub-buffer 1142. The specific arrangement method can be selected and adjusted according to actual design requirements. It is only necessary to ensure that the structure of the second through hole 115 is consistent with the structure of the first through hole 113. No special restrictions are made here.

[0045] Optional, such as Figure 1 、 Figure 2 and Figure 4 As shown, a glue overflow groove 122 is formed on the side of the glue filling plate 120 facing away from the electrical compartment 230. The glue overflow groove 122 is used to accommodate overflowed glue, that is, the glue overflow groove 122 is a blind hole. When the battery pack 10 is glued using the crossbeam glue filling tool 100, in order to ensure that the battery compartment 220 is filled with sufficient glue, it is necessary to allow part of the glue to overflow to the side of the glue filling plate 120 facing away from the electrical compartment 230. By forming the glue overflow groove 122 on the side of the glue filling plate 120 facing away from the electrical compartment 230, excess glue can flow into the glue overflow groove 122 during glue filling, thereby ensuring that the battery compartment 220 is fully filled with glue while preventing excess glue from overflowing into the battery compartment 220, thereby preventing glue overflow and contamination.

[0046] In some embodiments, the glue overflow groove 122 extends in a ring shape along the circumference of the glue filling plate 120, that is, the glue filling plate 120 can be set as a flat plate in the shape of a "U", so that the leveling effect of the glue can be improved during glue filling, and the excess glue can flow to the glue overflow grooves 122 around it, thereby preventing glue overflow and pollution.

[0047] In other embodiments, a plurality of glue filling holes 121 are provided on the glue filling plate 120, and the glue overflow groove 122 is arranged around the plurality of glue filling holes 121, that is, the glue overflow groove 122 is arranged in a manner of surrounding the glue filling holes 121, so that during glue filling, excess glue can directly flow into the glue overflow groove 122 close thereto, thereby avoiding the risk of glue overflow due to glue accumulation.

[0048] It should be noted that the specific structure of the glue overflow groove 122 on the glue filling plate 120 can be selected and adjusted according to actual design requirements. It only needs to ensure that the excess glue can flow smoothly into the corresponding glue overflow groove 122 during glue filling to avoid glue overflow. There is no special restriction here.

[0049] Optionally, the glue filling plate 120 is detachably connected to the crossbeam assembly 110, that is, when the battery pack 10 is glued using the crossbeam glue filling tool 100, the crossbeam glue filling tool 100 is first fixed as a whole in the box 200 by connecting the crossbeam assembly 110 to the box 200, and then the battery compartment 220 is glued using the glue filling holes 121 on the glue filling plate 120. After the glue filling is completed, the glue filling plate 120 can be disassembled to facilitate the removal of the glue filling plate 120. In other words, the crossbeam assembly 110 in the crossbeam glue filling tool 100 can be retained in the box 200 as part of the battery pack 10 to achieve isolation between the battery compartment 220 and the electrical compartment 230 in the box 200, while also helping to improve the overall structural strength of the battery pack 10. The removal of the glue filling plate 120 can reduce the impact on the assembly of the battery pack 10 and also reduce the weight of the battery pack 10.

[0050] In some embodiments, the glue filling plate 120 and the second crossbeam 112 are integrally formed, and the glue filling plate 120 and the box body 200 are detachably connected, that is, when the battery pack 10 is glued using the crossbeam glue filling tooling 100, the crossbeam glue filling tooling 100 is first fixed as a whole in the box body 200 through the connection between the crossbeam assembly 110 and the box body 200, and then the battery compartment 220 is glued using the glue filling holes 121 on the glue filling plate 120. After the glue filling is completed, the glue filling plate 120 and the second crossbeam 112 can be disassembled as a whole to facilitate the removal of the glue filling plate 120 and the second crossbeam 112. That is to say, only the first crossbeam 111 or the first crossbeam 111 and the buffer member 114 in the crossbeam assembly 110 are retained in the box body 200 as part of the battery pack 10 to isolate the battery compartment 220 and the electrical compartment 230 in the box body 200, while the glue filling plate 120 and the second crossbeam 112 are removed at the same time after glue filling to further reduce the weight of the battery pack 10.

[0051] In other embodiments, the crossbeam glue filling tool 100 can be integrally formed as part of the battery pack 10, that is, after the glue filling is completed, the crossbeam glue filling tool 100 is not removed but directly retained. Since the glue has a certain fluidity during glue filling, in order to prevent the glue from overflowing into the electrical compartment 230 during the glue filling process, the crossbeam glue filling tool 100 can be disassembled after the glue solidifies. At this time, the crossbeam glue filling tool 100 may be solidified into one with the glue due to the curing effect of the glue, which may cause damage to the structure of the battery pack 10 during the disassembly process. By directly forming the crossbeam glue filling tool 100 as a part of the battery pack 10 as a whole, the structural stability of the battery pack 10 after glue filling can be effectively guaranteed.

[0052] It should be noted that the specific connection method between the beam assembly 110 and the glue filling plate 120 in the beam glue filling tool 100 and the disassembly method after glue filling can be selected and adjusted according to actual design requirements. It is only necessary to ensure that the beam glue filling tool 100 can ensure the smooth glue filling of the battery pack 10 and does not cause damage to the overall structure of the battery pack 10. No special restrictions are made here.

[0053] Secondly, an embodiment of the present application provides a battery pack 10, which includes a crossbeam glue filling tool 100. The specific structure of the crossbeam glue filling tool 100 refers to the above embodiment. Since this battery adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0054] like Figure 4 and Figure 5As shown, the battery pack 10 is glued using the above-mentioned crossbeam glue-pouring tool 100. The battery pack 10 includes a box body 200 and a battery module. The box body 200 is formed with a receiving cavity 210. The receiving cavity 210 includes a battery compartment 220 and an electrical compartment 230. The battery module is disposed in the battery compartment 220. The crossbeam assembly 110 in the crossbeam glue-pouring tool 100 is used to be disposed in the box body 200 to divide the receiving cavity 210 into the battery compartment 220 and the electrical compartment 230. The glue-pouring plate 120 in the crossbeam glue-pouring tool 100 is used to correspond to the battery compartment 220 and cover the battery module so as to perform glue pouring into the battery compartment 220.

[0055] That is, when glue is being poured into the battery pack 10, the crossbeam glue pouring tooling 100 needs to be installed into the box body 200 first, so that the crossbeam assembly 110 in the crossbeam glue pouring tooling 100 is connected to the bottom of the box body 200, and at the same time, the accommodating cavity 210 of the box body 200 is divided into a battery compartment 220 and an electrical compartment 230. The glue pouring plate 120 automatically corresponds to the battery compartment 220 and covers the top of the battery module in the battery compartment 220. Glue can be poured into the battery compartment 220 through the glue pouring holes 121 on the glue pouring plate 120, and the crossbeam assembly 110 is arranged between the battery compartment 220 and the electrical compartment 230, which can play a good isolation role, preventing glue from overflowing from the battery compartment 220 into the electrical compartment 230 during glue pouring, thereby avoiding the electrical components in the electrical compartment 230 from being contaminated by glue.

[0056] The crossbeam glue filling tool 100 can be used as a part of the battery pack 10 as a whole, and can be retained in the box 200 as a whole after the glue filling is completed; or, the glue filling plate 120 in the crossbeam glue filling tool 100 is detachably connected to the crossbeam assembly 110. After the glue filling is completed, the glue filling plate 120 needs to be disassembled so that the glue filling plate 120 can be removed. That is, only the crossbeam assembly 110 in the crossbeam glue filling tool 100 is retained in the box 200 as a part of the battery pack 10; or The glue filling plate 120 in the beam glue filling tool 100 is integrally formed with the second beam 112, and the glue filling plate 120 is detachably connected to the box body 200. After the glue filling is completed, the glue filling plate 120 and the second beam 112 need to be disassembled as a whole to facilitate the removal of the glue filling plate 120 and the second beam 112, that is, only the first beam 111 or the first beam 111 and the buffer member 114 in the beam glue filling tool 100 remain in the box body 200 as part of the battery pack 10.

[0057] That is to say, the specific connection method between the beam assembly 110 and the glue filling plate 120 in the beam glue filling tool 100 and the disassembly method after glue filling directly affect the final structural composition of the battery pack 10, and the specific connection method between the beam assembly 110 and the glue filling plate 120 in the beam glue filling tool 100 and the disassembly method after glue filling can be selected and adjusted according to actual design requirements. It is only necessary to ensure that the beam glue filling tool 100 can ensure the smooth glue filling of the battery pack 10 and does not cause damage to the overall structure of the battery pack 10. Correspondingly, the structural composition of the battery pack 10 can also be adjusted accordingly, and there is no special restriction here.

[0058] The above is a detailed introduction to the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
