[0002] This application claims the benefit of Korean Patent Application No. 10-2023-0162370, filed on November 21, 2023, which is incorporated herein by reference. Technical Field

[0003] The invention relates to a front lower vehicle body structure. Background Art

[0004] Recently, vehicles with short front overhang designs have become popular.

[0005] The front overhang refers to the distance between the front of the vehicle and the wheel base.

[0006] A short front overhang vehicle can achieve a stylish and dynamic design, and can improve driving performance by bringing the end of the body closer to the center of the vehicle. In addition, a short front overhang vehicle has the advantage of being able to drive smoothly even in narrow alleys by reducing the minimum turning radius.

[0007] Furthermore, with the recent trend of shifting from internal combustion engine vehicles to electric vehicles, the collision absorption space tends to decrease. In other words, in order to improve the driving range of electric vehicles (EVs), the use of high-voltage batteries is increasing, and the overall weight of the vehicle is also increasing due to the installation of high-voltage batteries.

[0008] In other words, there is a risk of occupant injury due to a reduction in the impact absorbing space, and there is a possibility of fracture of the side members and the instrument panel surface due to an increase in the vehicle weight.

[0009] The contents described in the background technology section are provided to enhance understanding of the background of the embodiments of the present invention and may include contents that are not known prior arts. Summary of the invention

[0056] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

[0057] Figure 1 is a bottom perspective view of a front lower structure of a vehicle body according to an embodiment, and Figure 2 yes Figure 1 The view does not include the lower engaging member.

[0058] Figure 3 yes Figure 2 The view does not include the front side interior components, and Figure 4 yes Figure 3 The view does not include the rear lower member.

[0059] refer to Figures 1 to 4 According to the embodiment, the front lower structure 1 of the vehicle body may include: a front side inner member 10, which is arranged on the front lower part of the vehicle body along the front-rear direction of the vehicle body; an upper joining member 30, which is connected to the rear upper part of the front side inner member 10 and is arranged along the front-rear direction of the vehicle body; and a lower joining member 50, which is connected to the rear lower part of the front side inner member 10 and the lower part of the upper joining member 30 and is arranged along the front-rear direction of the vehicle body.

[0060] The front lower structure according to the embodiment may further include a rear lower member 70 connected to the upper and lower engaging members 30 and 50 and installed on rear portions of the upper and lower engaging members 30 and 50 .

[0061] The front lower structure 1 according to the embodiment may further include a front side outer member 90 connected to the front side inner member 10 , the upper joining member 30 , the lower joining member 50 , and the rear lower member 70 and installed on the outer side in the width direction of the vehicle body.

[0062] The front side inner member 10 , the upper joining member 30 , the lower joining member 50 , and the front side outer member 90 are connected to form a front side beam.

[0063] Figure 5 It is a perspective view of a front side inner member of the front lower structure of the vehicle body according to the embodiment.

[0064] refer to Figure 5 The front inner member includes: a front upper surface 12; a front inner surface 14, which is bent from the front upper surface 12; a front lower surface 16, which is bent from the front inner surface 14; and a front upper flange 18 and a front lower flange 20, which are bent from the front upper surface 12 and the front lower surface 16 respectively and connected to the front outer member 90.

[0065] In other words, the front side inner member 10 has a substantially U-shaped cross-sectional shape in which variation in the cross-sectional shape in the length direction is prevented, and therefore, the front side inner member 10 can be used as a common part for a plurality of vehicle types and the manufacturing cost can be reduced.

[0066] Figure 6 1 is a perspective view of an upper joint member of a front lower structure of a vehicle body according to an embodiment.

[0067] refer to Figure 5 and Figure 6The upper joining member 30 includes: an upper joining upper surface 32, connected to the front side upper surface 12; an upper joining upper flange 34, bent from the upper joining upper surface 32; an upper joining inner surface 36, connected to at least a portion of the front side inner surface 14; and an upper joining inner flange 38, bent from the upper joining inner surface 36.

[0068] Figure 7 1 is a perspective view of a lower joint member of a front lower structure of a vehicle body according to an embodiment.

[0069] refer to Figures 5 to 7 The lower joining member 50 includes: a lower joining lower surface 52 connected to the front side lower surface 16; a lower joining lower flange 54 bent from the lower joining lower surface 52; a lower joining inner surface 56 connected to at least a portion of the front side inner surface 14; and a lower joining inner flange 58 bent from the lower joining inner surface 56.

[0070] The lower engaging inner flange 58 may be combined with the upper engaging inner flange 38 .

[0071] The upper engaging member 30 and the lower engaging member 50 may further include an upper engaging front connecting portion 40 and a lower engaging front connecting portion 60 connected to the rear portion of the front inner member 10 , respectively.

[0072] For example, the upper engaging front connecting portion 40 and the lower engaging front connecting portion 60 have a stepped shape that prevents the front side inner member 10 from being pushed toward the rear of the vehicle body during a frontal collision of the vehicle.

[0073] Generally, a front side member is a very important member to cope with a vehicle collision, and the collision performance is determined by the material or thickness.

[0074] Furthermore, the cross-sectional dimensions of the front side member vary depending on its installation position, connectivity with other members, and the like, and flanges also need to be formed in various directions.

[0075] Therefore, the front side beam is a part that is relatively difficult to form.

[0076] In addition, due to the limitations of material selection and thickness, reinforcement components need to be added internally to improve collision performance.

[0077] refer to Figures 1 to 7 In the front lower structure of the vehicle body according to the embodiment, the front side inner member 10 has a very simplified shape compared to a common front side member, making it easy to improve collision performance by adjusting the material and thickness.

[0078] The upper engaging member 30 and the lower engaging member 50 are connected to each other and to the rear portion of the front inner member 10 .

[0079] In other words, the front side inner member 10 can simplify the manufacturing process by utilizing its simple shape, and can also be expected to improve the collision performance.

[0080] The upper engaging member 30 and the lower engaging member 50 are parts whose shapes can be relatively significantly changed and which can distribute the load from the front portion of the vehicle body to the rear portion of the vehicle body.

[0081] Conventional front side beams respond to collisions by increasing the thickness of the rear portion.

[0082] For example, when a tailor-welded blank (TWB) production line for properly distributing a collision load is applied, processing becomes complicated and manufacturing costs increase.

[0083] However, according to an embodiment of the front lower structure of the vehicle body, the shape is greatly simplified compared to a common side member, so that the collision performance can be improved by adjusting the material and the thickness.

[0084] Furthermore, by adjusting the length of the lower engaging member 50 in the front-rear direction of the vehicle body, the amount of deformation during a vehicle collision can be increased to reduce the RTE and suppress injury to the occupant.

[0085] Furthermore, by adjusting the length of the lower engaging member 50 in the height direction of the vehicle body, it is possible to control the amount of deformation (the amount of dent) in the height direction of the vehicle during a collision and suppress injury to the occupant.

[0086] The front lower structure according to the embodiment may further include an instrument panel 100 connected to a rear portion of the upper joining member 30 , an upper portion of the rear lower member 70 , and a rear portion of the front side outer member 90 .

[0087] The upper engaging member 30 may include an upper engaging rear flange 42 bent to be connected to the instrument panel 100 .

[0088] The upper engaging rear flange 42 includes an upper engaging rear upper flange 44 bent from the upper engaging upper surface 32 and formed at an upper portion of the upper engaging upper surface, and an upper engaging rear inner flange 46 bent from the upper engaging inner surface 36 and formed inside the upper engaging inner surface.

[0089] A general front side member is mounted on the front portion of the instrument panel and the bottom of the floor, has a relatively complex shape for connection to other parts, and is expensive to process.

[0090] In other words, due to the difficulty in molding the side member, a notch may be formed after manufacturing, and the flange size may be limited.

[0091] Therefore, when the vehicle collides, the front side member may penetrate the instrument panel and cause injury to occupants in the vehicle cabin.

[0092] However, in the front lower structure 1 according to the embodiment, the front side inner member 10 , the upper engaging member 30 , and the lower engaging member 50 are separately manufactured and relatively simplified parts are assembled to form the front side member.

[0093] Furthermore, the upper engaging rear upper flange 44 and the upper engaging rear inner flange 46 of the upper engaging rear flange 42 connected to the instrument panel 100 have relatively small size restrictions to properly distribute the impact load during a vehicle collision, and thus damage to the instrument panel 100 can be prevented.

[0094] In other words, the separately manufactured upper engaging member 30 can suppress the occurrence of notches due to its high degree of freedom in material selection and design.

[0095] A floor panel (not shown) is installed at the rear of the instrument panel 100 , and an upper portion of the floor panel defines a cabin space.

[0096] This combination relationship is obvious to those skilled in the art, so a detailed description will be omitted.

[0097] exist Figure 6 In the embodiment, by extending the length A of the upper engaging rear upper flange 44 , the ratio of the collision energy transmitted to the instrument panel 100 can be increased.

[0098] Furthermore, by increasing the length B of the upper engaging rear inner flange 46 , it is possible to prevent breakage by reinforcing the connectivity of the mating surfaces in front of the instrument panel 100 .

[0099] Figure 8 It is a perspective view of a rear lower member of the front lower structure of the vehicle body according to the embodiment.

[0100] refer to Figures 1 to 8 The rear lower member 70 may include: a rear lower member body 72 having a U-shaped cross-sectional shape; and a rear lower member flange 74 bent from the rear lower member body 72 and connected to the instrument panel 100 .

[0101] A front portion of the rear lower member 70 may be connected to a rear portion of the front inner member 10 .

[0102] The front inner member 10 is connected not only to the upper joining member 30 and the lower joining member 50 but also to the rear lower member 70 , so that the connectivity of the front lower structure 1 can be enhanced.

[0103] Fig. 9 It is along Figure 1 A cross-sectional view taken along line AA in FIG. Fig.10 It is along Figure 1 A cross-sectional view taken along line BB in FIG. Fig.11 It is along Figure 1 Cross-sectional view taken along line CC in FIG.

[0104] like Fig. 9 As shown, the front side outer member 90 and the front side inner member 10 having a substantially U-shaped cross-sectional shape form a front side beam by their combination.

[0105] Furthermore, the front side outer member 90 and the front side inner member 10 may form a closed cross section along the front-rear direction of the vehicle body to increase the strength of the vehicle body in the front-rear direction.

[0106] refer to Fig.10 , the upper coupling member 30 and the lower coupling member 50 are connected to form a coupling space 45 inside, and a portion of the rear lower member 70 may be connected to the inside of the coupling space 45 .

[0107] In other words, the rear lower member body 72 of the rear lower member 70 may be coupled to the lower joint lower surface 52 of the lower joint member 50 .

[0108] The lower engagement member 50 may include a lower engagement inner flange 58 connected to the instrument panel 100 via a rear lower member flange 74 .

[0109] The rear lower member flange 74 may be inserted and coupled between the lower joint inner flange 58 and the upper joint inner flange 38 , and the three flanges may be connected to increase joint strength and facilitate impact load distribution.

[0110] Furthermore, the rear lower member flange 74 is connected to the instrument panel 100 , so that the connectivity of the upper joint member 30 , the lower joint member 50 , and the instrument panel 100 can be enhanced.

[0111] like Fig.11 As shown, the rear lower member body 72 of the rear lower member 70 has a generally U-shape and is connected to the instrument panel 100 via a rear lower member flange 74 .

[0112] Furthermore, the rear lower member 70 and the instrument panel 100 form a closed space, and the closed space can increase the section modulus.

[0113] Fig.12 2 is a view showing a load transmission path of a front lower structure of a vehicle body according to an embodiment.

[0114] refer to Fig.12 In the front lower structure 1 according to the embodiment, when the vehicle collides, collision energy can be stably distributed to the instrument panel 100 and the floor of the vehicle body through the front inner member 10, the upper joining member 30, the lower joining member 50, and the rear lower member 70.

[0115] Furthermore, according to the front lower structure 1 according to the embodiment, the RDE of the portion where the upper joint member 30 , the lower joint member 50 , the rear lower member 70 , and the instrument panel 100 are connected increases, and thus the RTE can be reduced.

[0116] Furthermore, according to the front lower structure 1 according to the embodiment, the connection between the side beam and the instrument panel 100 in the front-rear direction of the vehicle body is strengthened, and the connection between the side beam and the rear lower member 70 can also be strengthened.

[0117] Furthermore, according to the front lower structure 1 according to the embodiment, the area occupied by the rear lower member 70 which is a relatively strong member increases, and the cross section of the side member and the cross section of the rear lower member 70 can be smoothly connected.

[0118] In addition, according to the front lower structure 1 according to the embodiment, it is possible to improve structural efficiency by relatively reducing the cutting area.

[0119] Furthermore, according to the embodiment of the front lower structure 1 , the collision performance of the side sill is improved, thereby reducing the need for an additional reinforcement member in the side sill.

[0120] Furthermore, according to the front lower structure 1 according to the embodiment, the connection between the side sill and the instrument panel is reinforced, the connection between the side sill and the rear lower member is reinforced, and the flanges are connected in three directions to prevent separation.

[0121] Although the embodiments of the present invention have been described in conjunction with what are currently considered to be practical embodiments, it should be understood that the embodiments of the present invention are not limited to the disclosed embodiments. Instead, they are intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
