Description

Technical Field

[0001] This disclosure relates to an anti-rotation device for a side sill of a vehicle, and more specifically, to a side sill anti-rotation device configured to prevent rotation of the side sill in the event of a side collision of the vehicle and to ensure the safety of the vehicle. Background Technology

[0002] The vehicle may include side beams and side beam reinforcements located on the lower side of the vehicle body. The side beams and side beam reinforcements can improve crash performance and ensure passenger survival space in the event of a side collision. In some cases, the side beams and side beam reinforcements can protect the battery during a side collision, thus helping to prevent the vehicle from catching fire.

[0003] To ensure the vehicle's crash performance, its structure can be achieved by analyzing, evaluating, and verifying the cross-sectional shape, size, and location of the side beams and side beam reinforcement members.

[0004] In some cases, electric vehicles may have a battery mounting structure that includes a battery array and supporting elements. In other cases, electric vehicles may have a structure in which the vehicle body and battery are integrated together.

[0005] When the side beams of an electric vehicle rotate excessively due to a side collision, the battery modules inside the battery casing may be damaged due to the rotation of the side walls of the battery casing. Furthermore, excessive rotation of the side beams may cause excessive deformation of the vehicle's pillars, which could negatively impact the survival space for passengers inside the vehicle. Various studies and developments have been conducted to reduce and prevent the rotation of the side beams. Summary of the Invention

[0029] In the accompanying drawings, throughout several figures, the same reference numerals refer to the same or equivalent parts of this disclosure. Detailed Implementation

[0030] In the following, various embodiments of this disclosure will be described in detail, examples of which are illustrated in the accompanying drawings and described below. Furthermore, the contents illustrated in the drawings are schematic to facilitate the explanation of embodiments of this disclosure and may differ from actual implementations.

[0031] In some implementations, such as Figure 1 As shown, the anti-rotation device for the side beams of a vehicle may include: a pair of inner side beam panels 1; a plurality of seat crossbars 2 disposed between the pair of inner side beam panels 1; and a plurality of extension brackets 3 configured to connect the inner side beam panels 1 to the seat crossbars 2.

[0032] A pair of side rail inner panels 1 are components configured to ensure the side impact performance of the vehicle body, and are respectively located at the lower left and lower right ends of the vehicle body. Each side rail inner panel 1 can extend in the longitudinal direction of the vehicle.

[0033] Seat crossbar 2 is arranged between the inner panels 1 of a pair of side rails and on seat 41 (see Figure 8Below the seat 41, the seat is configured for use by a user. The seat crossbar 2 is formed to extend in the left-right direction. The inner panels 1 of the side rails are respectively provided on opposite sides (i.e., the left and right sides) in the longitudinal direction of the seat crossbar 2. For example, the seat crossbar 2 may include a bar arranged below the seat 41 of the vehicle and extending horizontally across the seat 41.

[0034] In some embodiments, all of the plurality of seat crossbars 2 may have a first end and a second end connected to a pair of side rail inner panels 1. The first end of the seat crossbar 2 is connected to the first side rail inner panel 1a via a first extension bracket 3a, and the second end of the seat crossbar 2 is connected to the second side rail inner panel 1b via a second extension bracket 3b.

[0035] In some instances, the structural configuration in which the first end of the seat crossbar 2 is connected to the inner panel 1a of the first side rail via a first extension bracket 3a is substantially the same as the structural configuration in which the second end of the seat crossbar 2 is connected to the inner panel 1b of the second side rail via a second extension bracket 3b. Furthermore, the first extension bracket 3a and the second extension bracket 3b can be configured to have the same structure.

[0036] Therefore, in this specification, the connection structure of the seat crossbar 2 and the inner panel of the side rail beam 1 using either the first extension bracket 3a or the second extension bracket 3b will be described.

[0037] In some implementations, such as Figure 2 and Figure 3 As shown, the seat crossbar 2 and the inner panel 1 of the side rail are connected to each other via an extension bracket 3. Figure 4 and Figure 5 As shown, the extension bracket 3 may include a lower extension bracket 31 and an upper extension bracket 32. The lower extension bracket 31 and the upper extension bracket 32 ​​may be molded from steel of grade 60K or higher by a pressing method.

[0038] In some instances, such as in vehicles where the upper part of the battery casing 5 (i.e., the upper casing 52) serves as the floor panel of the vehicle body (i.e., vehicles where the battery and the vehicle body are integrally formed together), Figure 6 As shown, the lower part of the seat crossbar 2 is welded to the upper housing 52.

[0039] In some embodiments, the seat crossbar 2, used in vehicles where the battery and body are integrally formed, may not be connected to the extension bracket 3 by welding. This is because the welding torch cannot access the lower part of the seat crossbar 2. When the seat crossbar 2 is joined to the upper housing 52, the seat crossbar 2 and the upper housing 52 form a closed cross section. Therefore, it is impossible to join the seat crossbar 2 to the extension bracket 3 by spot welding. In some instances, the extension bracket 3 is bolted to the seat crossbar 2.

[0040] In some embodiments, the lower extension bracket 31 may be configured to physically connect the inner panel 1 of the side rail to the seat crossbar 2. The lower extension bracket 31 is connected to the seat crossbar 2 by bolts. More specifically, the lower extension bracket 31 connects the lateral end of the seat crossbar 2 to the inner panel 1 of the side rail by welding and bolts. That is, the lower extension bracket 31 is connected to the inner panel 1 of the side rail by welding and to the lateral end of the seat crossbar 2 by bolts.

[0041] In some instances, the lower extension support 31 may include a lower support body 311, a pair of lower support sidewalls 312 and 313, and a plurality of lower flanges 314, 315 and 316.

[0042] For example, the lower support body 311 may have a flat plate structure and be stacked and joined to the upper part of the seat crossbar 2. The lower support body 311 may be joined to the seat crossbar 2 by means of bolts and nuts. In some instances, the lower support body 311 includes a first lower mounting portion 3111 and a second lower mounting portion 3113.

[0043] The first lower mounting portion 3111 may define a plurality of first connecting holes 3112, and the second lower mounting portion 3113 may define a plurality of second connecting holes 3114. The first connecting holes 3112 are spaced apart from each other in the front-back direction, and the second connecting holes 3114 are also spaced apart from each other in the front-back direction. During assembly, bolts are inserted through the first connecting holes 3112 and the second connecting holes 3114, respectively. The second lower mounting portion 3113 is located between the first lower mounting portion 3111 and the first lower flange 314.

[0044] The lower support body 311 is provided with a second lower mounting part 3113 and a first lower mounting part 3111, thereby achieving a more stable connection with the seat crossbar 2.

[0045] In some embodiments, a pair of lower support sidewalls 312 and 313 can be bent and extended from the lower support body 311. The first lower support sidewall 312 can be bent downward from the rear edge of the lower support body 311 and extend downward, and the second lower support sidewall 313 can be bent downward from the front edge of the lower support body 311 and extend downward. In some cases, the angle formed between the lower support body 311 and the lower support sidewalls 312 and 313 can be an obtuse angle.

[0046] The first lower flange 314 is arranged on the opposite side of the first lower mounting portion 3111, wherein the second lower mounting portion 3113 is located between the first lower flange 314 and the first lower mounting portion 3111. The first lower flange 314 is provided on the right edge of the lower support body 311 and is joined to the upper wall portion 11 of the inner plate 1 of the side surround beam.

[0047] like Figure 3As shown, there is a height difference in the vertical direction between the upper part of the seat crossbar 2 and the upper wall portion 11 of the inner panel 1 of the side rail. Therefore, the lower support body 311 includes a downwardly inclined portion 3115 formed between the second lower mounting portion 3113 and the first lower flange 314.

[0048] In some embodiments, the second lower flange 315 may be bent and extend from the first lower bracket sidewall 312, and the third lower flange 316 may be bent and extend from the second lower bracket sidewall 313. More specifically, the second lower flange 315 may be bent rearward from the right edge of the first lower bracket sidewall 312. The third lower flange 316 may be bent forward from the right edge of the second lower bracket sidewall 313. In some instances, the right edges of the first lower bracket sidewall 312 and the second lower bracket sidewall 313 are edges facing outwards from the vehicle.

[0049] The second lower flange 315 and the third lower flange 316 can extend to the edge of the lower inclined portion 3115 and the edge of the first lower flange 314. The second lower flange 315 and the third lower flange 316 are joined by welding and fixed to the side wall portion 13 of the inner plate 1 of the side surround beam.

[0050] The inner panel 1 of the side wall beam is formed as a bent structure with a rectangular cross-section having one open side. The inner panel 1 of the side wall beam includes an upper wall portion 11 and a lower wall portion 12, and a side wall portion 13 extending between the upper wall portion 11 and the lower wall portion 12. The side wall portion 13 extends downward from one end of the upper wall portion 11 and extends to one end of the lower wall portion 12. In some embodiments, one end of the upper wall portion 11 and one end of the lower wall portion 12 are the ends facing the interior of the vehicle.

[0051] like Figures 2 to 5 As shown, the upper extension bracket 32 ​​is welded to the lower extension bracket 31 and supports the inner panel 1 of the side wall beam in the event of a side collision, thereby reducing or preventing rotation of the inner panel 1 of the side wall beam. The upper extension bracket 32 ​​prevents the inner panel 1 of the side wall beam from being pushed and rotated by the collision energy applied to the vehicle body in the lateral direction during a side collision.

[0052] The upper extension bracket 32 ​​is spot welded to the lower extension bracket 31 and the inner plate 1 of the side beam.

[0053] Specifically, the upper extension bracket 32 ​​includes an upper bracket body 321, a pair of upper bracket sidewalls 322 and 323, and a plurality of upper flanges 324, 326, 327 and 328.

[0054] The upper support body 321 is connected to the lower extension support 31 and the inner plate 1 of the side beam via a first upper flange 324. The first upper flange 324 is stacked and welded to the upper wall portion 11 of the inner plate 1 of the side beam, and the upper support body 321 extends laterally from the first upper flange 324. In this case, the upper support body 321 can extend horizontally from the first upper flange 324 and is aligned with the upper wall portion 11 of the inner plate 1 of the side beam.

[0055] Since the upper support body 321 and the upper wall portion 11 of the inner plate of the side beam are on the same straight line, the upper extension support 32 can effectively prevent the rotation of the inner plate of the side beam when the vehicle is involved in a side collision.

[0056] In some instances, the upper extension bracket 32 ​​can also prevent rotation of the side beam reinforcement member 14, which is disposed within the internal space of the inner panel 1 of the side beam. The internal space of the inner panel 1 of the side beam is a space enclosed by the upper wall portion 11, the lower wall portion 12, and the side wall portion 13. For example... Figure 3 As shown, the side beam reinforcement member 14 is mounted and disposed within the internal space of the inner plate 1 of the side beam via a mounting bracket 15. The mounting bracket 15 is welded and fixed to the inner plate 1 of the side beam. The side beam reinforcement member 14 is supported by the mounting bracket 15 in a state where it is inserted into and disposed within the internal space of the inner plate 1 of the side beam. The side beam reinforcement member 14 may be made of aluminum.

[0057] Furthermore, the upper support body 321 and the upper wall portion 11 of the inner plate 1 of the side beam are located on the same straight line, and the upper support body 321 is located above the lower support body 311 with a predetermined interval between the upper support body 321 and the lower support body 311.

[0058] In addition, refer to Figure 8 The upper support body 321 has a seat mounting hole 3213 through which the seat leg 4 is mounted. That is, the upper support body 321 includes a seat mounting hole 3213 configured to connect the upper support body 321 to the seat leg 4. The seat leg 4 may be an outer support leg installed on the first row of seats (i.e., the front seats) of the vehicle.

[0059] In some embodiments, a pair of upper support sidewalls 322 and 323 can be bent and extended from the upper support body 321. The first upper support sidewall 322 can be bent downward from the rear edge of the upper support body 321 and extend downward, and the second upper support sidewall 323 can be bent downward from the front edge of the upper support body 321 and extend downward. The first upper support sidewall 322 and the second upper support sidewall 323 are respectively spot-welded to the first lower support sidewall 312 and the second lower support sidewall 313.

[0060] In some examples, the upper support body 321 has an upwardly inclined portion 3211 disposed at one edge of the upper support body and formed to extend downwardly at an angle. The upwardly inclined portion 3211 extends between the upper support body 321 and a second upper flange 326. The second upper flange 326 bends from the lower end of the upwardly inclined portion 3211 and extends in the lateral direction. The second upper flange 326 is disposed on the opposite side of the first upper flange 324, wherein the upper support body 321 is located between the second upper flange 326 and the first upper flange 324. The second upper flange 326 is welded to the first lower mounting portion 3111.

[0061] In some embodiments, the second upper flange 326 may be disposed between and extend between the first end of the first upper bracket sidewall 322 and the first end of the second upper bracket sidewall 323. In some instances, the first ends of the first upper bracket sidewall 322 and the second upper bracket sidewall 323 are portions that extend further toward the vehicle center than the upper bracket body 321. More specifically, the second upper flange 326 extends from the upper edge of the first upper bracket sidewall 322 to the upper edge of the second upper bracket sidewall 323.

[0062] In some instances, the third upper flange 327 may be bent rearward and extend from the second end of the first upper support sidewall 322. The fourth upper flange 328 may be bent forward and extend from the second end of the second upper support sidewall 323. The third upper flange 327 and the fourth upper flange 328 are joined to the sidewall portion 13 of the inner plate 1 of the side rail beam by welding.

[0063] In some instances, the third upper flange 327 is joined to the side wall portion 13 of the side wall beam inner plate 1 with the second lower flange 315 sandwiched between the third upper flange 327 and the side wall portion 13, and the fourth upper flange 328 is joined to the side wall portion 13 with the third lower flange 316 sandwiched between the fourth upper flange 328 and the side wall portion 13 of the side wall beam inner plate 1.

[0064] In some instances, the first upper flange 324 is stacked and joined to the upper wall portion 11 with the first lower flange 314 sandwiched between the first upper flange 324 and the upper wall portion 11 of the inner plate 1 of the side rail beam. In other words, the first lower flange 314 is disposed and joined between the first upper flange 324 and the upper wall portion 11.

[0065] like Figure 6As shown, after the upper extension bracket 32 ​​and the lower extension bracket 31 are spot-welded to the upper wall portion 11 and the side wall portion 13 of the inner plate 1 of the side rail beam, the seat crossbar 2 is stacked on the lower side of the lower extension bracket 31. In some examples, the first lower mounting portion 3111 is stacked between the second upper flange 326 and the seat crossbar 2. Furthermore, the second lower mounting portion 3113 is stacked on the upper side of the seat crossbar 2 from the lower side of the upper bracket body 321.

[0066] Therefore, in order to connect the first lower mounting part 3111 to the seat crossbar 2 by bolting, a plurality of upper connecting holes 325 are provided in the second upper flange 326. When the first lower mounting part 3111 is connected to the seat crossbar 2 by bolting, the second upper flange 326 is bolted to the seat crossbar 2 through the upper connecting holes 325.

[0067] Furthermore, to connect the second lower mounting part 3113 to the seat crossbar 2 via bolts, a plurality of threaded through holes 3212 are formed in the upper bracket body 321. The threaded through holes 3212 are located above the second connecting hole 3114 formed in the second lower mounting part 3113 for bolt connection. That is, the threaded through holes 3212 and the second connecting hole 3114 are located on the same vertical line. The bolt connection operation of the second lower mounting part 3113 is performed through the threaded through holes 3212.

[0068] In addition, such as Figure 3 As shown, in order to improve the reinforcement efficiency of the side beam reinforcement member 14, the seat crossbar 2 is positioned on the same line as the side beam reinforcement member 14. Specifically, the seat crossbar 2 is positioned on the same horizontal line as the upper part of the side beam reinforcement member 14. Therefore, the reinforcement efficiency of the side beam reinforcement member 14 is improved, and the cross-sectional area of ​​the side beam reinforcement member 14 can be reduced, thereby reducing the weight of the side beam reinforcement member 14.

[0069] In addition, such as Figure 6 As shown, the seat crossbar 2, in its engaged state with the battery housing 5, is stacked on the underside of the extension bracket 3 and is engaged with the extension bracket 3. The seat crossbar 2 has an engagement flange 21 that is spot-welded to the upper housing 52 of the battery housing 5. The engagement flange 21 is provided at the lower part of the seat crossbar 2.

[0070] Specifically, the seat crossbar 2 is configured to include a transverse member body 22 and a connecting flange 21. The transverse member body 22 is stacked on the upper end of the upper housing 52 and is disposed between the lower extension bracket 31 and the upper housing 52. The transverse member body 22 is connected to the lower extension bracket 31 by bolts.

[0071] The engaging flange 21 extends from the lower end of the transverse member body 22 and overlaps and engages with the upper end of the upper housing 52. The engaging flange 21 bends from the lower end of the transverse member body 22 and extends outward from the transverse member body 22. The engaging flange 21 is respectively provided at the lower front end and the lower rear end of the transverse member body 22.

[0072] like Figure 7 As shown, the battery housing 5 is also joined to the lower wall portion 12 of the inner panel 1 of the side surround beam. The battery housing 5 includes a lower housing 51 and an upper housing 52.

[0073] The lower housing 51 has an internal space for accommodating the battery module 53 and a side member 511 bolted to the lower wall portion 12 of the inner side panel 1. The side member 511 protrudes from the side wall of the lower housing 51 and extends toward the inner side panel 1. For example, the side member 511 may comprise a block protruding from the side wall of the lower housing 51 and extending toward the inner side panel 1. The side member 511 is stacked below the lower wall portion 12 of the inner side panel 1. Figure 3 As shown, a watertight sealing foam 512 is provided on the upper part of the side member 511, between the side member 511 and the lower wall 12.

[0074] The upper housing 52 is configured to open and close the upper end of the lower housing 51, and overlaps and engages with the upper end of the lower housing 51. The upper housing 52 engages and overlaps with the lower part of the seat crossbar 2, and serves as the floor panel of the vehicle body. Therefore, the vehicle no longer needs to include a separate floor panel, thereby reducing weight.

[0075] In some instances, the outer panel of the side perimeter beam can cover the side perimeter beam reinforcement member 14, at which the outer panel of the side perimeter beam is joined and fixed to the inner panel 1 of the side perimeter beam.

[0076] The side beam anti-rotation device of this disclosure, configured as described above, first absorbs the impact energy generated by the deformation of the side beam reinforcement member 14 during a side collision, and then absorbs the impact energy generated by the deformation of the side wall of the lower housing 51. Subsequently, when the inner plate 1 of the side beam deforms and begins to rotate toward the vehicle interior, the upper extension bracket 32 ​​supports the inner plate 1 of the side beam and inhibits its rotation, thereby preventing further deformation and rotation of the lower housing 51. Therefore, it not only prevents damage to the battery module 53 and intrusion of the inner plate 1 of the side beam into the vehicle interior, but also ensures the survival space for occupants inside the vehicle.

[0077] It is evident from the above description that this disclosure provides the following effects.

[0078] First, since the extension bracket connects the inner panel of the side beam to the seat crossbar through a dual structure including a lower extension bracket and an upper extension bracket, it has the effect of reducing the rotation of the inner panel of the side beam and the side beam reinforcement member and preventing excessive rotation of the inner panel of the side beam and the side beam reinforcement member when the vehicle is involved in a side collision.

[0079] Secondly, in the event of a side collision, it can not only prevent damage to the battery module due to excessive rotation of the inner panel of the side beam, but also ensure the survival space for passengers inside the vehicle.

[0080] Furthermore, the impact stiffness of the extension bracket is improved because the sidewalls of the upper and lower extension brackets are joined together.

[0081] The effects of this disclosure are not limited to those described above, and those skilled in the art will clearly understand, based on the detailed description of the embodiments, other effects not mentioned herein.

[0082] The embodiments of this disclosure have been described in detail above, and the terms or words used in this specification and claims should not be construed as limited to their common or dictionary meanings. Furthermore, since the embodiments described in this specification and the configurations shown in the accompanying drawings are merely embodiments of this disclosure, the scope of this disclosure is not limited to the above-described embodiments. Various modifications and improvements made by those skilled in the art using the basic concepts of this disclosure as defined in the appended claims also fall within the scope of this disclosure.
