Description

Technical Field

[0001] This application relates to the field of automotive assembly technology, and in particular to a battery pack anti-collision connection structure and electrical equipment. Background Technology

[0002] The battery pack is a core component of electric vehicles and other electrical equipment. The battery pack includes multiple battery modules. The frame of the battery pack is the supporting structure of the battery pack. The frame includes a front beam, a rear beam, and side beams. The side beams are located between the front beam and the rear beam. The frame can fix and protect the battery modules.

[0003] In related technologies, anti-collision components are provided at both the front and rear ends of the battery pack frame. The anti-collision components are protective components at the front and rear ends of the battery pack. The anti-collision components can disperse the impact force and prevent the battery pack from being directly impacted. When it is necessary to connect the battery pack frame to the anti-collision components, bolts are usually used. Multiple bolts are threaded through and connected to the front beam and the anti-collision components as well as the rear beam and the anti-collision components, so that the bolts can connect the frame to the anti-collision components.

[0004] However, the bolts are installed perpendicular to the side beams of the frame. When the vehicle is impacted and the direction of the impact is parallel to the side beams, the bolts are installed perpendicular to the direction of the impact. The bolts mainly bear shear force. This design causes the impact force to be concentrated at the bolt connection and cannot be evenly distributed on the battery pack frame, thus reducing the impact resistance of the entire battery pack.

Conversely, when the vehicle is impacted in a direction perpendicular to the length direction of the side beam, the first mounting member can better withstand tensile or compressive forces, allowing it to effectively and evenly transfer the impact force to the front beam, rear beam, and side beam of the frame, thereby improving the battery pack's resistance to multi-directional impacts.

[0057] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] In the design of the battery pack, the front and rear ends of the frame are equipped with anti-collision components. These anti-collision components are key protective parts for the front and rear ends of the battery pack. Their main function is to disperse impact force and prevent the battery pack from being directly impacted, thereby protecting the battery modules from damage. When it is necessary to connect the battery pack frame to the anti-collision components, bolts are usually used to achieve this connection. Specifically, multiple bolts are inserted between the front beam and the anti-collision components and between the rear beam and the anti-collision components, and they are firmly fixed together by threaded connections. This connection method structurally ensures a tight fit between the anti-collision components and the frame.

[0060] However, the bolts are installed perpendicular to the side beams of the frame. This means that when the vehicle is impacted and the impact direction is parallel to the side beams, the bolt installation direction is perpendicular to the direction of the impact. In this case, the bolts mainly bear shear force. Due to the shear force, the impact force will be concentrated at the bolt connection and cannot be evenly distributed across the entire frame of the battery pack. This makes the bolt connection a weak point of stress concentration, reducing the impact resistance of the entire battery pack frame. When the vehicle suffers a strong impact, this design may cause damage to the bolt connection, thereby affecting the overall structural integrity of the battery pack and increasing the risk of damage to the battery modules.

[0061] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0062] Combination Figures 1 to 11 This application provides a battery pack anti-collision connection structure, including:

[0063] The frame 100 includes a front beam 110, a rear beam 120 and a side beam 130, with the side beam 130 disposed between the front beam 110 and the rear beam 120.

[0064] At least one connector 200 is provided between the connector 200, the front beam 110 and the anti-collision member 500 disposed on the side of the front beam 110 away from the side beam 130, and the rear beam 120 and the anti-collision member 500 disposed on the side of the rear beam 120 away from the side beam 130.

[0065] The first mounting component 300 is used to detachably connect the connector 200 to the front beam 110 and the rear beam 120. The assembly direction of the first mounting component 300 is set along the length direction perpendicular to the side beam 130.

[0066] The second mounting component 400 is used to detachably connect the connector 200 to the front beam 110 and the rear beam 120. The assembly direction of the second mounting component 400 is set along the length direction parallel to the side beam 130.

[0067] In this embodiment, the front beam 110 and the rear beam 120 are parallel and spaced apart. Two side beams 130 are provided, which are respectively located between the two ends of the front beam 110 and the rear beam 120. The side beams 130 are perpendicular to the front beam 110 and the rear beam 120. One end of the side beam 130 is connected to the front beam 110, and the other end is connected to the rear beam 120. Two anti-collision members 500 are provided, which are respectively located opposite to the front beam 110 and the rear beam 120. Two connectors 200 are provided between the front beam 110 and one of the anti-collision members 500, which are respectively located at the two ends of the front beam 110. Two connectors 200 are provided between the rear beam 120 and the other anti-collision member 500, which are respectively located at the two ends of the rear beam 120.

[0068] In other embodiments, the number and position of the connectors 200 between the front beam 110 and the rear beam 120 and the anti-collision member 500 can be adaptively adjusted as needed. For example, one connector 200 can be provided between the front beam 110 and the rear beam 120 and the anti-collision member 500, and the connector 200 can be located in the middle of the front beam 110 and the rear beam 120. Alternatively, three connectors 200 can be provided between the front beam 110 and the rear beam 120 and the anti-collision member 500, and the three connectors 200 can be evenly and spaced apart along the length direction of the front beam 110 and the rear beam 120.

[0069] In this embodiment, the anti-collision component 500 includes a first anti-collision beam 510 and a second anti-collision beam 520. The first anti-collision beam 510 is parallel to the front beam 110 and the rear beam 120. There are two second anti-collision beams 520, which are respectively disposed at both ends of the first anti-collision beam 510. The second anti-collision beams 520 are perpendicular to the first anti-collision beam 510, and one end of the second anti-collision beam 520 is connected to the first anti-collision beam 510.

[0070] In this application, by employing a first mounting member 300 and a second mounting member 400, with the first mounting member 300 perpendicular to the length direction of the side beam 130 and the second mounting member 400 parallel to the length direction of the side beam 130, when the vehicle is impacted in a direction parallel to the length direction of the side beam 130, the second mounting member 400 can better withstand tensile or compressive forces. The tensile strength of the second mounting member 400 is stronger than the shear strength of the first mounting member 300, thereby enabling the second mounting member 400 to effectively and evenly transfer the impact force to the frame 10. In the front beam 110, rear beam 120 and side beam 130 of the frame 100, local stress concentration is reduced, and the risk of local failure caused by the fracture of the first mounting component 300 is reduced, thereby improving the impact resistance of the battery pack. When the vehicle is hit and the impact direction is perpendicular to the length direction of the side beam 130, the first mounting component 300 can better withstand the tensile or compressive force, so that the first mounting component 300 can effectively and evenly transfer the impact force to the front beam 110, rear beam 120 and side beam 130 of the frame 100, thereby improving the multi-directional impact resistance of the battery pack.

[0071] The connector 200 is provided with one of a protrusion 140 and a groove 210, and the front beam 110 and the rear beam 120 are provided with the other of a protrusion 140 and a groove 210. The protrusion 140 is used to insert into or disengage from the groove 210 to connect the connector 200 to the front beam 110 and the rear beam 120.

[0072] In this embodiment, the groove 210 is provided on the connector 200, and the protrusion 140 is provided on the front beam 110 and the rear beam 120. The insertion direction of the protrusion 140 and the groove 210 is set along the length direction parallel to the side beam 130. Two protrusions 140 are provided on both the front beam 110 and the rear beam 120, and the two protrusions 140 are respectively provided in a one-to-one correspondence with the two connectors 200. The protrusions 140 are integrally provided on the front beam 110 and the rear beam 120, thereby improving the connection strength between the protrusions 140 and the front beam 110 and the rear beam 120.

[0073] In other embodiments, the shapes of the protrusion 140 and the groove 210 can be adapted as needed, and the insertion direction of the protrusion 140 and the groove 210 can also be set along the length direction perpendicular to the side beam 130.

[0074] In this application, by employing the protrusion 140 and the groove 210, the protrusion 140 and the groove 210 can position the connector 200 on the front beam 110 and the rear beam 120, thereby improving the ease of installation of the connector 200 with the front beam 110 and the rear beam 120; when the protrusion 140 is inserted into the groove 210, when the vehicle is impacted, because the insertion direction of the protrusion 140 and the groove 210 is set along the length direction parallel to the side beam 130, the protrusion 140 and the groove 210 can also transmit the impact force to the frame 100, thereby indirectly improving the impact resistance of the frame 100.

[0075] The protrusion 140 has a rectangular cross-section. The rectangular protrusion 140 includes a top surface 141, a bottom surface 142, and a side surface 143. At least one first mounting member 300 is provided on the top surface 141, the bottom surface 142, and the side surface 143. The first mounting member 300 is used to detachably connect the protrusion 140 and the groove 210 so as to detachably connect the connector 200 to the front beam 110 and the rear beam 120.

[0076] In this embodiment, the protrusion 140 is a cuboid, and the groove 210 is configured to cooperate with the cuboid protrusion 140. The four faces of the cuboid protrusion 140 adjacent to the front beam 110 and the rear beam 120 are the top surface 141, the bottom surface 142, and the two side surfaces 143, respectively. Two first mounting members 300 are provided on the top surface 141, the bottom surface 142, and the two side surfaces 143. The two first mounting members 300 on the top surface 141, the bottom surface 142, and the two side surfaces 143 are spaced apart along the length direction of the front beam 110 and the rear beam 120. The assembly directions of the two first mounting members 300 on the top surface 141 and the bottom surface 142 are opposite to each other, and the assembly directions of the two first mounting members 300 on the two side surfaces 143 are opposite to each other.

[0077] In other embodiments, the shape of the protrusion 140 can be adaptively adjusted as needed. For example, the protrusion 140 can be set as a cylinder, and the groove 210 can be matched with the cylindrical protrusion 140. By evenly distributing multiple first mounting members 300 around the cylindrical protrusion 140, the assembly direction of each first mounting member 300 can form multiple assembly directions, thereby further improving the battery pack's resistance to multi-directional impacts. The number and position of the first mounting members 300 on the top surface 141, bottom surface 142, and side surface 143 can be adaptively adjusted as needed.

[0078] In this application, by setting the protrusion 140 as a rectangle, first mounting members 300 can be provided on the top surface 141, bottom surface 142, and two side surfaces 143 of the rectangular protrusion 140. Furthermore, the assembly directions of the first mounting members 300 on the top surface 141, bottom surface 142, and two side surfaces 143 are all perpendicular to the length direction of the side beam 130. The assembly directions of the first mounting members 300 on the top surface 141 and bottom surface 142 are perpendicular to the assembly directions of the first mounting members 300 on the two side surfaces 143, so that when the vehicle is impacted, the top surface... The first mounting members 300 on the top surface 141, bottom surface 142, and two side surfaces 143 can withstand the impact force of the vehicle, thereby improving the connection strength between the front beam 110 and rear beam 120 and the anti-collision member 500. When the impact direction is parallel to the assembly direction of the first mounting members 300, the first mounting members 300 on the top surface 141, bottom surface 142, and two side surfaces 143 can transmit the impact force to the frame 100 in different directions, thereby further distributing the impact force evenly on the frame 100, and further improving the impact resistance of the battery pack.

[0079] A first groove 144 is provided on the protrusion 140, and a first reinforcing rib 145 is provided inside the first groove 144.

[0080] In this embodiment, the cross-section of the first groove 144 is rectangular, and the surface of the first groove 144 away from the front beam 110 and the rear beam 120 is through.

[0081] In other embodiments, the cross-section of the first groove 144 may be circular or polygonal.

[0082] In this application, by adopting the first groove 144 and the first reinforcing rib 145, the material used in the production of the protrusion 140 is reduced, thereby reducing the weight of the protrusion 140 and preventing the protrusion 140 from increasing the overall vehicle weight. The first reinforcing rib 145 improves the strength of the protrusion 140 itself, thereby preventing the protrusion 140 from breaking and indirectly improving the bearing capacity of the protrusion 140 against impact force when the vehicle is hit.

[0083] The first reinforcing rib 145 includes a plurality of reinforcing plates 146 arranged in a cross pattern, and the plurality of reinforcing plates 146 are all disposed within the first groove 144.

[0084] In this embodiment, four reinforcing plates 146 are provided. Two reinforcing plates 146 are arranged along the length direction perpendicular to the front beam 110 and the rear beam 120. One side of the reinforcing plate 146 is connected to the top wall of the first groove 144, and the other side is connected to the bottom wall of the first groove 144. The other two reinforcing plates 146 are arranged along the length direction parallel to the front beam 110 and the rear beam 120. One side of the reinforcing plate 146 is connected to one side wall of the first groove 144, and the other side is connected to the other side wall of the first groove 144. Two reinforcing plates 146 and the other two reinforcing plates 146 are arranged in a cross shape.

[0085] In other embodiments, the reinforcing plate 146 may also be configured as circular, polygonal, or honeycomb-shaped, etc.

[0086] In this application, by employing multiple cross-arranged reinforcing plates 146, the strength of the protrusion 140 is further improved, thereby preventing damage to the protrusion 140 and indirectly improving the bearing capacity of the protrusion 140 against impact force when the vehicle is subjected to an impact.

[0087] The first mounting component 300 includes a first bolt 310, which passes through one of the connector 200 and the protrusion 140. A first nut 320 is provided on the other of the connector 200 and the protrusion 140. The first bolt 310 is used for threaded connection with the first nut 320.

[0088] In this embodiment, the first bolt 310 is inserted through the connector 200, and the first nut 320 is disposed in the first groove 144 of the protrusion 140; there are eight first bolts 310 and eight first nuts 320, with each of the eight first bolts 310 and the eight first nuts 320 corresponding one-to-one, and two first nuts 320 are disposed on the inner walls of the top surface 141, the bottom surface 142 and the two side surfaces 143.

[0089] In this application, when it is necessary to fix the protrusion 140 and the groove 210, the first bolt 310 is inserted into the connector 200, so that the shank of the first bolt 310 is inserted into the groove 210. At this time, the first bolt 310 can be inserted and threaded into the first nut 320 of the protrusion 140, thereby fixing the protrusion 140 and the groove 210. The use of the first bolt 310 and the first nut 320 makes the operation simple, the installation and disassembly process fast and efficient, and the reliability high. Through precise thread fit and appropriate tightening torque, the firmness and stability can be ensured, effectively resisting the impact force when the vehicle is hit.

[0090] The second mounting component 400 includes a second bolt 410, which passes through one of the connector 200 and the frame 100. A second nut 420 is provided on the other of the connector 200 and the frame 100. The second bolt 410 is used for threaded connection with the second nut 420.

[0091] In this embodiment, the second bolt 410 passes through the connector 200, and the second nut 420 is disposed on the front beam 110 and the rear beam 120 of the frame 100; there are four second bolts 410 and four second nuts 420, with each of the four second bolts 410 and the four second nuts 420 corresponding one-to-one; two of the second bolts 410 are disposed on one side of one side 143 of the protrusion 140, and the other two second bolts 410 are disposed on the other side 143 of the protrusion 140.

[0092] In this application, when the protrusion 140 and the groove 210 are fixed by the first bolt 310 and the first nut 320, thereby fixing the frame 100 to the connector 200, the second bolt 410 is inserted into and threadedly connected to the second nuts 420 of the front beam 110 and the rear beam 120, thereby further fixing the connector 200 and the frame 100 by the second bolt 410 and the second nut 420. The use of the second bolt 410 and the second nut 420 makes the operation simple, the installation and disassembly process fast and efficient, and the reliability high. Through precise thread fit and appropriate tightening torque, the firmness and stability can be ensured, effectively resisting the impact force when the vehicle is hit.

[0093] In other embodiments, the first mounting member 300 and the second mounting member 400 may also be replaced by rivets or clips.

[0094] The connector 200 includes a connecting beam 220, one end of which is connected to the frame 100 and the other end is connected to the anti-collision member 500. The cross-sectional area of ​​the connecting beam 220 gradually decreases along the direction away from the frame 100.

[0095] In this embodiment, one end of the connecting beam 220 is connected to the front beam 110 and the rear beam 120, and the other end is connected to the first anti-collision beam 510 of the anti-collision member 500. The two connecting beams 220 are respectively disposed at both ends of the first anti-collision beam 510.

[0096] In this application, by gradually reducing the cross-sectional area of ​​the connecting beam 220, this structure is mechanically referred to as a "variable cross-section beam." The design of the variable cross-section beam can better adapt to the stress requirements at different locations. The cross-sectional area of ​​the connecting beam 220 near the ends of the front beam 110 and the rear beam 120 is larger, which can withstand greater stress concentration, while the cross-sectional area of ​​the connecting beam 220 near the end of the first anti-collision beam 510 is smaller, which can reduce the overall weight while maintaining sufficient strength. When subjected to impact force, the connecting beam 220 can effectively disperse and absorb energy. By gradually reducing the cross-sectional area, the impact force is evenly transmitted to the entire beam, avoiding the problem of excessive local stress. In addition, the variable cross-section design also improves the bending stiffness and torsional stiffness of the beam, making it exhibit higher stability and deformation resistance when subjected to complex loads.

[0097] The cross-section of connecting beam 220 is polygonal.

[0098] In this embodiment, the cross-section of the connecting beam 220 is quadrilateral; in other embodiments, the cross-section of the connecting beam 220 may also be circular, pentagonal, or irregular in shape.

[0099] In this application, by setting the cross-section of the connecting beam 220 to a quadrilateral, the material can be utilized more effectively, providing a larger moment of inertia. This significantly improves the bending stiffness and torsional stiffness of the connecting beam 220 with the same amount of material. This design exhibits higher stability when subjected to lateral loads and torques, reducing deformation. At the same time, the quadrilateral cross-section of the connecting beam 220 provides more contact area and more stable support when connected to the frame 100, enhancing the connection strength and reliability between the connecting beam 220 and the front beam 110 and the rear beam 120.

[0100] The connecting beam 220 is arc-shaped, with the notch of the arc-shaped connecting beam 220 facing upwards.

[0101] In other embodiments, the notch of the arc-shaped connecting beam 220 may also face downwards, or the notch of the arc-shaped connecting beam 220 may face to the left or right in the horizontal direction, or the connecting beam 220 may be set to a wavy shape.

[0102] In this application, by setting the connecting beam 220 to an arc shape, when the connecting beam 220 is subjected to impact force, it can absorb and disperse energy through its own bending deformation, thereby effectively reducing the concentration of force. Furthermore, the arc-shaped connecting beam 220 increases the moment of inertia of the cross section, improving the bending stiffness and strength of the connecting beam 220, making it less prone to breakage or deformation when subjected to large impact forces.

[0103] A second groove 230 is provided on at least one of the opposite sides of the connecting beam 220. The second groove 230 is provided along the length direction of the connecting beam 220, and a second reinforcing rib 231 is provided inside the second groove 230.

[0104] In this embodiment, the connecting beam 220 is provided with a second groove 230 on both opposite sides along the horizontal direction, and the cross section of the second groove 230 is U-shaped.

[0105] In this embodiment, the head of the first bolt 310, which is opposite to the two sides 143 of the protrusion 140, is disposed in the second groove 230, and the heads of the plurality of second bolts 410 are disposed in the second groove 230.

[0106] In this application, by providing second reinforcing ribs 231 on both opposite sides of the connecting beam 220, the structural strength and impact resistance of the connecting beam 220 can be significantly improved. The second reinforcing ribs 231 can effectively increase the local stiffness of the connecting beam 220, reduce bending and torsional deformation under stress, thereby improving its overall stability under large loads. This design can also optimize stress distribution, avoid stress concentration, further enhance the fatigue resistance of the connecting beam 220, and extend the service life of the connecting beam 220. Furthermore, the provision of the second groove 230 reduces the overall weight of the connecting beam 220.

[0107] The second reinforcing rib 231 includes a first reinforcing part 232 and a second reinforcing part 233. The first reinforcing part 232 is arranged along the length direction of the second groove 230, and the second reinforcing part 233 is arranged between the opposite sides of the first reinforcing part 232 and the inner wall of the second groove 230.

[0108] In this embodiment, the first reinforcing part 232 is arc-shaped, and the notch of the arc-shaped first reinforcing part 232 faces upward.

[0109] In this application, by adopting the first reinforcing part 232 and the second reinforcing part 233, the structural strength and impact resistance of the connecting beam 220 can be further improved, thereby further reducing the bending and torsional deformation of the connecting beam 220 under stress.

[0110] The second reinforcing part 233 includes multiple reinforcing segments 234 connected end to end. One end of each reinforcing segment 234 is connected to the inner wall of the second groove 230, and the other end of each reinforcing segment 234 is connected to the first reinforcing part 232. The multiple reinforcing segments 234 are arranged along the length direction of the first reinforcing part 232.

[0111] In this embodiment, the multiple reinforcing segments 234 are arranged in a wavy shape.

[0112] In this application, by employing multiple reinforcing segments 234, the surface area and moment of inertia of the material can be effectively increased, thereby significantly improving the bending stiffness and torsional stiffness of the first reinforcing rib 145, enabling the connecting beam 220 to exhibit higher stability and deformation resistance when subjected to larger loads; the wavy multiple reinforcing segments 234 perform well in absorbing and dispersing impact energy, and can disperse the point of force application through their undulating shape when subjected to impact, reducing direct impact, thereby improving the impact resistance of the connecting beam 220.

[0113] Along the direction away from the frame 100, the distance between the ends of adjacent reinforcing segments 234 away from the first reinforcing part 232 gradually decreases.

[0114] In this embodiment, nine reinforcing segments 234 are provided, and adjacent reinforcing segments 234 are arranged in a "V" shape.

[0115] In this application, the multiple reinforcing segments 234 that are far from the front beam 110 and the rear beam 120 are arranged more densely, while the multiple reinforcing segments 234 that are close to the front beam 110 and the rear beam 120 are arranged more loosely. The dense arrangement of the multiple reinforcing segments 234 can effectively improve the structural strength and impact resistance of the end of the connecting beam 220 near the first anti-collision beam 510, thereby preventing the end of the connecting beam 220 near the first anti-collision beam 510 from breaking due to its small cross-sectional area.

[0116] In other embodiments, the spacing between adjacent reinforcing segments 234 may be equal along the direction away from the frame 100, or the spacing between adjacent reinforcing segments 234 may be gradually increased.

[0117] A third groove 240 is provided on at least one of the other two opposite sides of the connecting beam 220. The third groove 240 is provided along the length direction of the connecting beam 220, and a third reinforcing rib 241 is provided inside the third groove 240.

[0118] In this embodiment, the upper and lower parts of the quadrilateral connecting beam 220 are provided with a third groove 240, and the cross section of the third groove 240 is U-shaped.

[0119] In this embodiment, the head of the first bolt 310, which is opposite to the top surface 141 and bottom surface 142 of the protrusion 140, is located outside the third groove 240.

[0120] In this application, by providing third reinforcing ribs 241 at both the upper and lower parts of the connecting beam 220, the structural strength and impact resistance of the connecting beam 220 can be further improved. The third reinforcing ribs 241 can further increase the local stiffness of the connecting beam 220, reduce bending and torsional deformation under stress, thereby improving its overall stability under large loads. This design can also optimize stress distribution, avoid stress concentration, further enhance the fatigue resistance of the connecting beam 220, and extend the service life of the connecting beam 220. Furthermore, the provision of the third groove 240 further reduces the overall weight of the connecting beam 220.

[0121] The third reinforcing rib 241 includes a third reinforcing part 242 and a fourth reinforcing part 243. The third reinforcing part 242 is arranged along the length direction of the third groove 240. Multiple fourth reinforcing parts 243 are arranged between the opposite sides of the third reinforcing part 242 and the inner wall of the third groove 240. One side of the fourth reinforcing part 243 is connected to the third reinforcing part 242, and the other side of the fourth reinforcing part 243 is connected to the inner wall of the third groove 240.

[0122] In this embodiment, the third reinforcing part 242 is arc-shaped, and the notch of the arc-shaped third reinforcing part 242 faces upward. There are four fourth reinforcing parts 243, which are perpendicular to the third reinforcing parts 242. Along the direction away from the front beam 110 and the rear beam 120, the spacing between adjacent fourth reinforcing parts 243 gradually decreases.

[0123] In this application, by adopting the third reinforcing part 242 and the fourth reinforcing part 243, the structural strength and impact resistance of the connecting beam 220 can be further improved, thereby further reducing the bending and torsional deformation of the connecting beam 220 under stress. The multiple fourth reinforcing parts 243 far away from the front beam 110 and the rear beam 120 are arranged more densely, while the multiple fourth reinforcing parts 243 near the front beam 110 and the rear beam 120 are arranged more loosely. The dense arrangement of multiple fourth reinforcing parts 243 can effectively improve the structural strength and impact resistance of the end of the connecting beam 220 near the first anti-collision beam 510, thereby preventing the end of the connecting beam 220 near the first anti-collision beam 510 from breaking due to its small cross-sectional area.

[0124] The battery pack anti-collision connection structure also includes a fixing member 600 and a third mounting member 700. The fixing member 600 is connected to the connecting member 200. Multiple third mounting members 700 are provided. The third mounting members 700 are used to detachably connect the fixing member 600 and the anti-collision member 500. The assembly direction of the third mounting member 700 is set along the length direction perpendicular to the side beam 130.

[0125] In this application, by employing the fastener 600 and the third mounting member 700, the anti-collision member 500 and the connector 200 can be detachably connected via the fastener 600 and the third mounting member 700, thereby facilitating the fixation of the anti-collision member 500. By aligning the assembly direction of the third mounting member 700 perpendicular to the length direction of the side beam 130, when the vehicle is impacted and the impact direction is perpendicular to the length direction of the side beam 130, the third mounting member 700 can better withstand tensile or compressive forces, effectively and evenly transmitting the impact force to the front beam 110, rear beam 120, and side beam 130 of the frame 100, thereby improving the battery pack's resistance to multi-directional impacts. When the vehicle is impacted and the impact direction is parallel to the length direction of the side beam 130, the multiple third mounting members 700 can withstand the impact force of the vehicle, thereby improving the connection strength between the front beam 110 and rear beam 120 and the anti-collision member 500.

[0126] The fastener 600 includes a fixed beam 610, and a receiving groove 611 is formed between the fixed beam 610 and the connector 200. The receiving groove 611 is used to receive part of the anti-collision component 500.

[0132] In this application, by adopting a first side plate 613 and setting six third mounting members 700 on the first side plate 613, the fixing strength between the fixed beam 610 and the anti-collision member 500 is indirectly improved, thereby preventing the fixed beam 610 and the anti-collision member 500 from separating when the vehicle is hit, and further improving the impact resistance of the fixed beam 610 and the connecting beam 220; when the impact direction of the vehicle is parallel to the assembly direction of the third mounting members 700, the six third mounting members 700 can transmit the impact force to the fixed beam 610 and the connecting beam 220, thereby facilitating the transmission of the impact force to the entire frame 100 and improving the battery pack's resistance to multi-directional impacts.

[0133] The fixed beam 610 also includes a second side plate 614, which is disposed on the base plate 612. The second side plate 614 is parallel to and spaced apart from the first side plate 613.

The assembly directions of the third mounting members 700 on the first side plate 613 and the third mounting members 700 on the second side plate 614 are opposite to each other.

[0135] In this application, by employing a second side plate 614 and providing two third mounting members 700 on the second side plate 614, the fixing strength between the fixed beam 610 and the anti-collision member 500 is further improved, thereby preventing the fixed beam 610 from separating from the anti-collision member 500 when the vehicle is impacted, and further improving the impact resistance of the fixed beam 610 and the connecting beam 220; when the impact direction of the vehicle is parallel to the assembly direction of the third mounting member 700, the multiple third mounting members 700 on the first side plate 613 and the second side plate 614 can transmit the impact force to the fixed beam 610 and the connecting beam 220, thereby facilitating the further transmission of the impact force to the entire frame 100 in different directions, and further improving the battery pack's resistance to multi-directional impacts.
