Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, and in particular to a side beam blocking component, a battery pack side beam and a battery pack box. Background Art

[0002] The side beams of vehicle battery packs are usually made by extrusion molding, and the side beams are designed with cavities inside, which ensure the structural strength and rigidity of the side beams while reducing their weight. In order to improve the thermal insulation performance of the battery pack and reduce the noise generated by the air flowing inside the side beam cavity during the driving of the vehicle, the two ports of the side beams are usually sealed with plugging parts.

[0003] In the related art, the plugging parts are usually in the form of metal plugging pieces or foam glue to plug the two ends of the side beam, thereby playing the role of plugging the side beam cavity. However, when the metal plugging piece is used, the metal plugging piece is connected to the side beam by welding. The welding process is relatively complicated, requiring professional skills and equipment, and the operation time is long, and the equipment cost is high. In addition, the welding process requires high temperature and high energy input, which will cause the side beam to deform due to heat, affecting its working reliability. When the foam glue is used, the foam glue is prone to failure and fall off after long-term use in the environment, and the durability is poor. Utility Model Content

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0032] like Figures 1 to 11 As shown, the side beam plugging member 100 of the embodiment of the utility model comprises a plugging piece 1 and a clamping structure. The clamping structure comprises a first clamping fin 2 and a second clamping fin 3, the first clamping fin 2 and the second clamping fin 3 are arranged at intervals along a thickness direction perpendicular to the plugging piece 1, and a clamping groove 4 is formed between the first clamping fin 2 and the second clamping fin 3. Of course, the clamping groove 4 can also be formed by the first clamping fin 2, the second clamping fin 3 and the plugging piece 1, and the clamping groove 4 is used to fix the plugging piece 1.

[0033] When installing the side beam sealing member 100 of the embodiment of the utility model, the sealing piece 11 is clamped on the two ends of the side beam 200 through the clamping groove 44, so that the sealing piece 11 seals the side beam 200. The first clamping fin 22 and the second clamping fin 33 can prevent the sealing piece 11 from rotating or flipping due to external force, so as to enhance the connection stability between the sealing piece 11 and the side beam 200. Compared with the related art, the side beam sealing member 100 of the embodiment of the utility model does not require welding installation, does not require complex welding processes and professional equipment, and reduces operation time and equipment costs. In addition, the problem of heat deformation of the side beam 200 is avoided, and the original shape and working reliability of the side beam 200 are maintained. In addition, there is no need to consider the problem of permanent failure and falling off due to environmental aging, and the durability is good.

[0034] In some embodiments, the side beam sealing member 100 of the utility model embodiment includes an elastic clip 5 arranged in the clamping groove 4, and the elastic clip 5 includes two oppositely arranged first clamping plates 501 and second clamping plates 502, and a clamping groove 504 is formed between the first clamping plates 501 and the second clamping plates 502, and the slot direction of the clamping groove 504 is the same as the slot direction of the clamping groove 4.

[0035] When installing the blocking piece 100, the first clamping plate 501 and the second clamping plate 502 are clamped on the side beam 200. Since the elastic clip 5 can be elastically deformed when subjected to external force, the elastic deformation force of the elastic clip 5 is used to clamp and fix the clamping groove 504 and the side beam 200, making the blocking piece 100 easy and convenient to install. In addition, when the blocking piece 100 is subjected to a certain degree of impact or vibration, the elastic deformation of the elastic clip 5 can adapt to and absorb these forces without causing the blocking piece 100 to fall off or be damaged, which helps the blocking piece 100 maintain its working reliability in a long-term vibration environment.

[0036] Optionally, the elastic clip 5 may be arranged in a U-shape, a C-shape or a V-shape.

[0037] In some embodiments, an elastic claw 503 is provided on the side inner wall of at least one of the first clamping plate 501 and the second clamping plate 502, and in the relative direction between the first clamping plate 501 and the second clamping plate 502, the elastic claw 503 is inclined toward the direction close to the blocking sheet 1. In other words, the elastic claw 503 may be provided only on the side inner wall of the first clamping plate 501, or only on the side inner wall of the second clamping plate 502, or both of the first clamping plate 501 and the second clamping plate 502.

[0038] Since, in the relative direction between the first clamping plate 501 and the second clamping plate 502, the elastic claw 503 is inclined toward the direction close to the blocking piece 1, the inclined setting of the elastic claw 503 can play a guiding role, so that the elastic member can be quickly clamped on the side beam 200 to improve the installation efficiency. After the installation is completed, the elastic claw 503 can form an undercut structure, which can effectively prevent the side beam 200 from falling out of the clamping groove 4, help reduce the loosening phenomenon that may occur during the use of the blocking member 100, and can improve the durability and reliability of the blocking member 100, and ensure the long-term sealing of the side beam 200.

[0039] In addition, since the elastic claw 503 can undergo elastic deformation when subjected to external force, this design can also provide a certain self-adjustment capability, which means that even if the sealing piece 100 encounters some slight deviations or deformations during installation or use, the elastic claw 503 can adapt to these changes and ensure that the sealing piece 100 always remains in the correct position.

[0040] In some embodiments, the elastic claw 503 includes a first claw 5031 and a second claw 5032. A plurality of first claws 5031 are provided on the first clamp plate 501, and a plurality of second claws 5032 are provided on the second clamp plate 502. In the relative direction of the first clamp plate 501 and the second clamp plate 502, at least one first claw 5031 and a second claw 5032 are arranged opposite to each other.

[0041] For example, Figures 5 to 7 As shown, at least one first claw 5031 is arranged opposite to the second claw 5032, so that the two opposite first claws 5031 and second claws 5032 form a stable supporting structure, forming an inverted structure to stop on both sides of the side beam 200, so as to provide better structural symmetry and uniformly distributed stress, which can further effectively prevent the side beam 200 from escaping from the clamping groove 4, help to reduce the loosening phenomenon that may occur in the sealing member 100 during use, and can improve the durability and reliability of the sealing member 100, and ensure the long-term sealing of the side beam 200.

[0042] Alternatively, if Figures 5 to 7 As shown, the first claw 5031 and the second claw 5032 are arranged in groups and there are multiple groups. The multiple groups of first claws 5031 and second claws 5032 are arranged at intervals in the thickness direction of the sealing piece 1 or in the width direction of the elastic clip 5, so that the elastic clip 5 has multiple clamping and fixing forces on the side beam 200 at different positions, which is beneficial to improve the installation stability of the sealing piece 100.

[0043] Alternatively, if Figure 7 and Figure 8 As shown, the first clamping claw 5031 is formed by bending a part of the side wall of the first clamping plate 501. Since the first clamping claw 5031 is formed by bending a part of the side wall of the first clamping plate 501, this can reduce the process and material costs in the production process, improve production efficiency, and reduce production costs. In addition, the clamping force of the first clamping claw 5031 can be increased, and the stability and safety can be improved.

[0044] Alternatively, if Figure 7 and Figure 8 As shown, the second clamping claw 5032 is formed by bending a portion of the side wall of the second clamping plate 502. Since the second clamping claw 5032 is formed by bending a portion of the side wall of the second clamping plate 502, this can reduce the process and material costs in the production process, improve production efficiency, and reduce production costs. In addition, the clamping force of the second clamping claw 5032 can be increased, and the stability and safety can be improved.

[0045] In some embodiments, Figure 8 As shown, the first clamping plate 501 has a first avoidance hole that penetrates the first clamping plate 501 along its thickness direction, and the projection of the first clamping claw 5031 is located within the projection of the first avoidance hole on a projection plane orthogonal to the thickness direction of the first clamping plate 501. This design can simplify the manufacturing process of the elastic clamp 5 to a certain extent, because the opening of the first avoidance hole can facilitate the bending of the side inner wall of the first clamping plate 501 to form the first clamping claw 5031, which is conducive to improving the processing and manufacturing efficiency of the first clamping claw 5031.

[0046] In some embodiments, the second clamping plate 502 has a second avoidance hole that penetrates the second clamping plate 502 along its thickness direction, and the projection of the second clamping claw 5032 is located within the projection of the second avoidance hole on a projection plane orthogonal to the thickness direction of the second clamping plate 502. This design can simplify the manufacturing process of the elastic clamp 5 to a certain extent, because the opening of the second avoidance hole can facilitate the bending of the side inner wall of the second clamping plate 502 to form the second clamping claw 5032, which is conducive to improving the processing and manufacturing efficiency of the second clamping claw 5032.

[0047] In some embodiments, a first limiting groove 201 and a second limiting groove 301 are respectively opened on the side inner walls of the first clamping fin 2 and the second clamping fin 3, and the free end of the first clamping plate 501 and the free end of the second clamping plate 502 are far away from each other and extend into the first limiting groove 201 and the second limiting groove 301 respectively.

[0048] For example, Figure 6 As shown, the first limiting groove 201 can limit the position of the first clamping plate 501 of the elastic clamp 5, and the second limiting groove 301 can limit the position of the second clamping plate 502 of the elastic clamp 5, so as to ensure that the elastic clamp 5 is in a proper position, prevent the elastic clamp 5 from falling off from the clamping groove 4, increase the fixity and stability of the elastic clamp 5, and further improve the working reliability of the blocking member 100.

[0049] Optionally, the blocking piece 1, the first clamping fin 2 and the second clamping fin 3 are integrally injection molded. That is, the blocking piece 1, the first clamping fin 2 and the second clamping fin 3 can be integrally injection molded as a whole. The use of integral injection molding can simplify the manufacturing process, reduce assembly steps, reduce production costs, and improve production efficiency. At the same time, integral injection molding can also improve the overall structural strength and stability of the blocking piece 100, and ensure the tightness and stability between the various parts of the blocking piece 100.

[0050] Optionally, the elastic clip 5 is formed by sheet metal stamping. Since the plugging member 100 needs to be in contact with the side beam 200 for a long time after installation, setting the elastic clip 5 as a sheet metal part can improve its wear resistance and anti-aging performance. During the long-term use of the plugging member 100, it can avoid the influence of severe wear or severe aging on its reliability, and can improve the reliability of the plugging member 100.

[0051] In addition, the sheet metal stamping process can accurately control the size and shape of the parts, ensuring that the elastic clip 5 is perfectly matched with the plugging piece 1 and other components. Sheet metal stamping forming generally also has high production efficiency and can reduce manufacturing costs. The elastic clip 5 is manufactured using the sheet metal stamping forming process, which can not only improve the performance of the plugging piece 100, but also improve production efficiency and reduce costs.

[0052] Optionally, the thickness of the elastic claw 503 is 1 mm-3 mm. For example, the thickness of the elastic claw 503 is 1 mm, 2 mm or 3 mm. Selecting a thinner thickness can reduce the overall weight of the plugging member 100, improve its lightweight design, and is suitable for scenes with strict weight requirements. Selecting a thicker thickness can increase the strength and stability of the elastic clip 5, and is suitable for scenes that need to withstand greater forces or require higher strength.

[0053] When the thickness of the elastic claw 503 is set to 1.0 mm, the 1.0 mm thick elastic claw 503 is light in weight, which helps to reduce the weight of the overall structure and can reduce material and manufacturing costs. When the weight of the elastic claw 503 is relatively small, the 1.0 mm thick elastic claw 503 is sufficient for use.

[0054] When the thickness of the elastic claw 503 is set to 2 mm, the thickness of 2 mm provides a good balance between strength and weight, and is suitable for application scenarios that require appropriate strength without adding too much weight. The material cost of the elastic claw 503 of this thickness is relatively moderate, neither as low-cost as the thinnest option nor as expensive as the thick option. For fixing the blocking piece 11 of medium weight, the 2 mm thick elastic claw 503 can provide sufficient support.

[0055] When the thickness of the elastic claw 503 is set to 3.0 mm, the 3.0 mm thick elastic claw 503 has higher strength and rigidity, and can withstand greater loads and more extreme working conditions. Thicker elastic claws 503 are more durable, and for fixing a heavy blocking piece 1, the 3.0 mm thick elastic claw 503 provides more reliable support.

[0056] In some embodiments, Fig. 9 As shown, the blocking piece 1 is provided with a reinforcing rib 6 on at least one side in the thickness direction, that is, the blocking piece 1 can be provided with a reinforcing rib 6 on one side or both sides in the thickness direction. Figure 8 As shown, there are two reinforcing ribs 6, which are arranged at intervals in the width direction of the blocking piece 1, and the reinforcing ribs 6 extend along the length direction of the blocking piece 1. The strength and rigidity of the blocking piece 1 can be enhanced by arranging the reinforcing ribs 6 on the blocking piece 1, thereby improving its structural stability. The design of the reinforcing ribs 6 can also effectively disperse the stress of the blocking piece 1, thereby preventing deformation or damage when subjected to external forces.

[0057] In some embodiments, at least a portion of the edge of the blocking piece 1 is provided with a flange 7 , and the flange 7 is bent along the thickness direction of the blocking piece 1 toward a direction close to the clamping groove 4 .

[0058] like Fig. 9 and Fig.10As shown, after the blocking piece 1 is installed on the side beam 200, the flange 7 on the edge of the blocking piece 1 can better fit the surface of the side beam 200, and the flange 7 set on the edge of the blocking piece 1 is used to further block the assembly gap between the two, forming a tighter sealing effect. In addition, the design of the flange 7 can also enhance the structural strength and stability of the blocking piece 1, and prevent deformation or damage during use.

[0059] The utility model also discloses a battery pack side beam 200, which includes a transverse plate 8, a longitudinal plate 9 and a side beam blocking member 100 described in any of the above embodiments. The transverse plate 8 and the longitudinal plate 9 enclose a cavity 10. The blocking member 100 is provided at least at one end of the side beam 200 in the length direction thereof, the clamping groove 4 is clamped on the transverse plate 8 or the longitudinal plate 9, and the blocking sheet 1 is attached to the end surface of each of the transverse plate 8 and the longitudinal plate 9.

[0060] Specifically, Figures 1 to 3 As shown, when sealing the two ends of the side beam 200, the snap-in groove 4 is snapped onto the longitudinal plate 9 of the side beam 200, and the sealing sheet 1 is fitted onto the end face of each of the transverse plate 8 and the longitudinal plate 9, so as to achieve the sealing of the cavity 10 by the sealing sheet 1. The thermal insulation performance of the battery pack itself is improved, and at the same time, the noise generated by the flow of air inside the cavity 10 of the side beam 200 when the vehicle is driving. Compared with the related art, when sealing the cavity 10 of the battery pack side beam 200 of the embodiment of the utility model, no welding installation method is required, and no complicated welding process and professional equipment are required, which reduces the operation time and equipment cost. In addition, the problem of heat deformation of the side beam 200 is avoided, and the original shape and working reliability of the side beam 200 are maintained. In addition, there is no need to consider the problem of falling off due to environmental aging and durable failure, and the durability is good.

[0061] Optionally, if the battery pack side beam 200 is large in size, it usually has multiple transverse plates 8 and longitudinal plates 9. Multiple clamping structures can be set on the sealing piece 1 to clamp the transverse plates 8 or longitudinal plates 9 at different positions of the side beam 200 to enhance the installation stability of the sealing piece 1.

[0062] In some embodiments, the first clamping plate 501 and the second clamping plate 502 of the elastic clamp 5 are clamped on the transverse plate 8 or the longitudinal plate 9. When installing the blocking member 100, the first clamping plate 501 and the second clamping plate 502 are clamped on the transverse plate 8 or the longitudinal plate 9 of the side beam 200. Since the elastic clamp 5 can be elastically deformed when subjected to external force, the elastic deformation force of the elastic clamp 5 is used to achieve the clamping and fixing between the clamping groove 504 and the transverse plate 8 and the longitudinal plate 89 on the side beam 200, making the blocking member 100 simple and convenient. In addition, when the blocking member 100 is subjected to a certain degree of impact or vibration, the elastic deformation of the elastic clamp 5 can adapt to and absorb these forces without causing the blocking member 100 to fall off or be damaged, which helps the blocking member 100 maintain its working reliability in a long-term vibration environment.

[0063] In some embodiments, the elastic claw 503 abuts against the side wall of the transverse plate 8 or the longitudinal plate 9 in the relative direction between the first clamping plate 501 and the second clamping plate 502 .

[0064] Since, in the relative direction between the first clamping plate 501 and the second clamping plate 502, the elastic claw 503 is inclined toward the direction close to the blocking piece 1, the inclined setting of the elastic claw 503 can play a guiding role, so that the elastic member can be quickly clamped on the transverse plate 8 or the longitudinal plate 9 of the side beam 200 to improve the installation efficiency. After the installation is completed, the elastic claw 503 can form an undercut structure, which can effectively prevent the transverse plate 8 or the longitudinal plate 9 of the side beam 200 from falling out of the clamping groove 4, which helps to reduce the loosening phenomenon that may occur in the blocking member 100 during use, and can improve the durability and reliability of the blocking member 100, and ensure the long-term sealing of the side beam 200.

[0065] In addition, since the elastic claw 503 can undergo elastic deformation when subjected to external force, this design can also provide a certain self-adjustment capability, which means that even if the sealing piece 100 encounters some slight deviations or deformations during installation or use, the elastic claw 503 can adapt to these changes and ensure that the sealing piece 100 always remains in the correct position.

[0066] In some embodiments, the flange 7 is attached to the outer surface of the side beam 200. Fig. 9 and Fig.10 As shown, after the blocking piece 1 is installed on the side beam 200, the flange 7 on the edge of the blocking piece 1 can better fit the outer surface of the side beam 200, and the flange 7 set on the edge of the blocking piece 1 is used to further block the assembly gap between the two, forming a tighter sealing effect. In addition, the design of the flange 7 can also enhance the structural strength and stability of the blocking piece 1, and prevent deformation or damage during use.

[0067] The utility model also discloses a battery pack box, comprising the battery pack side beam 200 described in any of the above embodiments. Therefore, the battery pack box of the utility model embodiment has the advantages of high manufacturing efficiency, low cost and good durability.
