Description

Technical Field

[0001] The present invention relates to a side beam forming the lower part of the side of a vehicle, and more specifically, to a side beam reinforcement member for a side beam of a vehicle, which is installed inside the side beam along the longitudinal direction of the vehicle to support collision loads input in the width direction of the vehicle. Background Technology

[0002] The side beams are positioned along the longitudinal direction of the vehicle on the lower part of the side of the vehicle.

[0003] like Figure 1 As shown, the side beam 102 includes an inner side beam member 111 that protrudes inward from the vehicle and an outer side beam member 112 that protrudes outward from the vehicle, and the upper and lower ends of the inner side beam member 111 and the outer side beam member 112 are connected to form a hollow structure in the longitudinal direction of the vehicle.

[0004] To increase the rigidity of the side beam 102, a side beam reinforcing member 120 is provided inside the side beam 102. For example... Figure 1 As shown, the side beam reinforcement member 120 is manufactured by extruding aluminum alloy and installed inside the side beam 102, thereby improving the rigidity of the side beam 102.

[0005] The tube nut 130 is installed in the side beam 102 for mounting the battery, other components, etc. of the electric vehicle.

[0006] However, the side beam reinforcement 120 is manufactured by extruding aluminum alloy, which increases the vehicle's production cost. Assembling the aluminum alloy side beam reinforcement 120 requires additional processes and manpower, further increasing the vehicle's production cost.

[0007] Furthermore, the side beam reinforcement member 120, made of aluminum alloy, presents the problem of being difficult to assemble in the narrow cross-sectional area of ​​the side beam 102. In vehicles with sliding doors, such as multi-purpose vehicles (MPVs), the cross-section of the side beam at the lower part of the sliding door is relatively small, making it difficult to assemble the aluminum alloy reinforcement member therein.

[0008] Thus, when the side beam reinforcement member 120 is not tightly assembled inside the side beam 102, uncoated areas are created during painting due to the narrow internal space of the side beam, leading to corrosion of the side beam 102.

[0009] In particular, during a side collision, the side beam 102 and the side beam reinforcement member 120 are unable to support or absorb the collision load input to the side of the vehicle, and the side beam 102 will enter the passenger compartment, thus hindering the reduction of injury to the passengers. Summary of the Invention

[0010] The present invention aims to provide a side beam reinforcement member, wherein a plurality of sub-reinforcement members arranged along the longitudinal direction of the vehicle are connected to support the collision load in the event of a side collision.

[0011] According to the present invention, the side beam reinforcing member includes a first sub-reinforcing member and a second sub-reinforcing member, the first sub-reinforcing member and the second sub-reinforcing member being arranged as a plurality of alternating members in the longitudinal direction of the vehicle, a portion of the first sub-reinforcing member being arranged above the second sub-reinforcing member, and another portion of the first sub-reinforcing member being arranged below another second sub-reinforcing member, the other second sub-reinforcing member being arranged relative to the second sub-reinforcing member in the longitudinal direction of the vehicle, and the plurality of alternating members in the longitudinal direction of the vehicle being installed inside the side beam of the vehicle.

[0019] A recess is provided in the first upper surface or the second upper surface, through which a tube nut passes, and the recess is configured to be lower than the first upper surface or the second upper surface.

[0020] The side beam reinforcement further includes: a third sub-reinforcement member, which is connected at the front end of the assembly of the first and second sub-reinforcement members to one of the first and second sub-reinforcement members arranged in the foremost position; and a fourth sub-reinforcement member, which is connected to the lower part of a third upper surface disposed on the third sub-reinforcement member.

[0021] The third sub-reinforcing member includes: a third upper surface; a third lower surface arranged lower than the third upper surface; a third intermediate flange disposed between the third upper surface and the third lower surface; a third rear flange connected at the rear end of the third sub-reinforcing member to the lower surface of the first intermediate flange of the first sub-reinforcing member or the second intermediate flange of the second sub-reinforcing member; a first front joint connected at the front end of the third sub-reinforcing member to the front pillar of the vehicle; and a support portion connected between the first front joint and the third upper surface to the inner upper surface of the side beam.

[0033] In addition, by using thin metal sheets to manufacture reinforcing components, weight can be reduced, thereby improving the vehicle's fuel efficiency or energy efficiency.

[0034] Because there is ample space inside the side beams, the paint can flow through the space during the painting process, thus allowing for uniform coating inside the side beams and preventing corrosion. Attached Figure Description

[0046] Hereinafter, the side beam reinforcement member for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

[0047] In the side beam reinforcement member for a vehicle according to the present invention, a first sub-reinforcing member 21 and a second sub-reinforcing member 22 are alternately arranged as a plurality of members in the longitudinal direction of the vehicle. A portion of the first sub-reinforcing member 21 is arranged above the second sub-reinforcing member 22, and another portion of the first sub-reinforcing member 21 is arranged below the second sub-reinforcing member 22. The front end of the first sub-reinforcing member 21 is connected to the upper middle part of the second sub-reinforcing member 22, and the rear end of the first sub-reinforcing member 21 is connected to the lower middle part of the second sub-reinforcing member 22. The side beam reinforcement member for the side beam of the vehicle is installed inside the side beam 2 of the vehicle.

[0048] like Figure 2 and Figure 3 As shown, the side beam 2 of vehicle 1 includes an inner side beam member 11 that protrudes inward from vehicle 1 and an outer side beam member 12 that protrudes outward from vehicle 1.

[0049] The upper and lower ends of the inner side member 11 and the outer side member 12 of the side beam are connected to form a hollow structure in the longitudinal direction of the vehicle 1, thereby forming the lower structure of the side of the vehicle 1.

[0050] The front end, middle end and rear end of the side beam 2 are connected to the front pillar, middle pillar and rear pillar of vehicle 1, respectively.

[0051] Meanwhile, in vehicles such as multi-purpose vehicles (MPVs), sliding doors can be mounted using the side beam 2. That is, the guide for sliding the door is parallel to the side beam 2, and the cross-sectional area of ​​the side beam 2 is reduced, making it easier for passengers to get in and out. Therefore, it is difficult to apply reinforcing members made of aluminum alloy to the interior of the side beam.

[0052] Therefore, in this invention, a plurality of sub-reinforcing members arranged along the longitudinal direction of vehicle 1 are connected to form side beam reinforcing members 20.

[0053] Figures 2 to 5 An example of a side beam reinforcement member 20 for a vehicle according to the present invention is shown.

[0054] The side beam reinforcement member 20 according to the present invention is constructed by arranging a plurality of sub-reinforcing members 21, 22 in the longitudinal direction of the vehicle and fastening the plurality of sub-reinforcing members 21, 22.

[0056] The first sub-reinforcing member 21 and the second sub-reinforcing member 22 are fastened such that the cylindrical structure arranged along the width direction of the vehicle 1 is positioned between the upper surfaces 21a and 22a and the lower surfaces 21b and 22b.

[0057] The side beam reinforcement member 20 is configured as a plurality of members arranged by alternating first sub-reinforcing members 21 and second sub-reinforcing members 22, and the first sub-reinforcing members 21 and second sub-reinforcing members 22 are connected to form the basic structure of the side beam reinforcement member 20.

[0058] A portion of the first sub-reinforcing member 21 is arranged above the second sub-reinforcing member 22, and another portion of the first sub-reinforcing member 21 is arranged below another second sub-reinforcing member 22 arranged in the longitudinal direction of the vehicle relative to the second sub-reinforcing member. The front end of the first sub-reinforcing member 21 is connected to the upper middle part of the second sub-reinforcing member 22, and the rear end of the first sub-reinforcing member 21 is connected to the lower middle part of the other second sub-reinforcing member 22.

[0076] Similar to the first sub-reinforcing member 21, the second sub-reinforcing member 22 also has a convex shape configured relative to the second upper surface 22a and a concave shape configured relative to the second lower surface 22b, which are configured along the longitudinal direction of the vehicle.

[0077] Figure 7 The diagram shows the connection relationship between the first sub-strengthening member 21 and the second sub-strengthening member 22, which form the basic structure of the side beam strengthening member 20.

[0078] The first sub-reinforcing member 21 and the second sub-reinforcing member 22 are each configured as multiple members, and the first sub-reinforcing member 21 and the second sub-reinforcing member 22 are arranged alternately in the longitudinal direction of the vehicle.

[0079] Referring to the connection relationship between the first sub-reinforcing member 21 and the second sub-reinforcing member 22, the second front flange 22d of the other second sub-reinforcing member 22 is connected to the upper part of the first intermediate flange 21c of the first sub-reinforcing member 21, and the first rear flange 21e of the first sub-reinforcing member 21 is connected to the lower surface of the other second intermediate flange 22c.

[0082] This connection structure is repeated along the length of vehicle 1 to form the basic structure that becomes the middle part of the side beam reinforcement member 20.

[0083] Therefore, the first sub-reinforcing member 21 and the second sub-reinforcing member 22 are connected such that the first upper surface 21a is arranged above the second lower surface 22b, and the second upper surface 22a is arranged above the first lower surface 21b.

The tube nut 30 can be used to install the battery of an electric vehicle and to connect the first sub-reinforcing member 21 to the second sub-reinforcing member 22, thereby increasing the rigidity of the side beam reinforcing member 20.

[0116] The first rear joint 25m is disposed in the height direction of the vehicle and is connected to the rear pillar of the vehicle or the second rear joint 26m, which will be described below, at the rear end of the fifth sub-reinforcing member 25. The first rear joint 25m extends upward from the vehicle to the upper part of the vehicle at the rear end of the fifth lower surface 25b and is connected to the rear pillar of the vehicle or the second rear joint 26m.

[0117] The sixth reinforcing member 26 is in Figure 6F As shown in the image.

[0118] The sixth sub-reinforcing member 26 includes a fifth upper surface 26a, a fourth front flange 26d connected to the upper surface of the fourth intermediate flange 25c, and a second rear joint 26m connected to the first rear joint 25m.

[0119] The fifth upper surface 26a is disposed in the longitudinal direction of the vehicle. The fifth upper surface 26a is arranged above the fifth lower surface 25b of the fifth sub-reinforcing member 25 to form a space therebetween. The fifth upper surface 26a is connected to the inner upper surface of the inner member 11 of the side beam or the inner upper surface of the outer member 12 of the side beam.

[0120] The fourth front flange 26d is disposed at the front end of the sixth sub-reinforcing member 26 and is connected to the upper surface of the fourth intermediate flange 25c. The fourth front flange 26d is connected to the fifth upper surface 26a via the sixth upper front connecting portion 26f. The fourth front flange 26d is connected to the upper surface of the fourth intermediate flange 25c, such that the front end of the sixth sub-reinforcing member 26 is connected to the fifth sub-reinforcing member 25. The third front flange 25d is connected to the fourth upper surface 25a via the fifth upper front connecting portion 25f.

[0121] The second rear joint 26m is disposed at the rear end of the fifth upper surface 26a in the vehicle height direction. The second rear joint 26m extends downward from the rear end of the fifth upper surface 26a. The first rear joint 25m and the second rear joint 26m are arranged to overlap each other and are connected together to the rear pillar. Therefore, the rear end of the side beam reinforcement member 20 is connected to the rear pillar.

[0122] The sixth sub-reinforcing member 26 may have a third recess 26j through which the tube nut 30 passes, and the third recess 26j is configured to be lower than the fifth upper surface 26a.

[0123] Since the side beam reinforcement member 20 is configured by connecting multiple sub-reinforcement members, a space is provided to form a cylindrical structure in the width direction of the vehicle, thereby the side beam reinforcement member 20 supports the collision load and reduces the deformation of the side beam 2. Therefore, it is possible to prevent the side beam 2 and the front pillar, middle pillar and rear pillar connected to the side beam 2 from deforming and entering the vehicle, thereby reducing injury to passengers.

[0124] Figure 10 A side beam reinforcement member 20 according to another embodiment of the present invention is shown.

[0125] The flanges arranged on the sub-strengthening members 21, 22, 23, 24, 25, and 26 that constitute the side beam strengthening member 20 are pre-inclined at a predetermined angle θ relative to the horizontal plane.

[0126] For example, refer to Figure 10 The first intermediate flange 21c can be configured to be inclined, and the second front flange 22d and the second rear flange 22e, which are respectively connected to the upper and lower surfaces of the first intermediate flange 21c, can also be configured to be inclined at corresponding angles.

[0127] In this way, by forming the flanges in an inclined manner, the portions connected by the flanges can be configured with acute angles, thereby increasing the rigidity of the flanges. For example, when the first intermediate flange 21c is configured to be inclined, the second front flange 22d forms an acute angle with the second upper front connecting portion 22f, and the second rear flange 22e forms an acute angle with the second lower rear connecting portion 22i. Therefore, the rigidity of the front and rear ends of the second sub-reinforcing member 22 can be increased.

[0128] Similarly, the second intermediate flange 22c, the third intermediate flange 23c and the fourth intermediate flange 25c can be configured to be inclined, and the flanges connected thereto can also be configured to be inclined accordingly.

[0129] Figure 11 A side beam reinforcement member 20 according to another embodiment of the present invention is shown.

[0130] In this embodiment, a sub-reinforcing member can be configured as multiple members.

[0131] For example, such as Figure 11 As shown, the second sub-reinforcing member 22 is configured as multiple members, and when each member is connected, a fastener 22n is configured on one member so that multiple members can be connected by welding, adhesion, fastening device, etc. using the fastener 22n.

[0132] Because the part connected by the fastener 22n has a thicker cross section than the other parts, rigidity can be increased.

[0133] Figure 11 The second sub-reinforcing member 22 is shown, but the first sub-reinforcing member 21 and the third to sixth sub-reinforcing members 23 to 26 can be configured as multiple members, and the multiple members are configured to be connected.
