[0053] The following description is merely exemplary in nature and is not intended to limit the present invention, its application, or uses. It should be understood that in all the drawings, corresponding reference numerals denote the same or corresponding parts and features.

[0054] In the drawings, for clarity, the thicknesses of layers, films, panels, regions, etc. are exaggerated.

[0055] When a component such as a layer, film, region, or plate is referred to as being "on" another component, this includes not only the case where it is directly on the other component, but also the case where there is another component between the two.

[0056] Conversely, when an element is referred to as being "directly on" another element, there is no intermediate element.

[0057] Throughout the specification, when a component "comprises" a certain component, it means that other components can be further included rather than excluding other components, unless there is a contrary specific statement.

[0058] A detailed description of an embodiment of the present invention will be given below with reference to the accompanying drawings.

[0059] Figure 2 is a perspective view of a hood mounting structure according to an embodiment of the present invention, Figures 3 to 5 is a partial perspective view of a hood mounting structure according to an embodiment of the present invention, Figure 6 is along Figure 2 a cross-sectional view taken along line V-V in

[0060] In Figure 2 T represents the longitudinal direction of the vehicle body, H represents the height direction of the vehicle body, and L represents the width direction of the vehicle body.

[0061] Referring to Figures 2 to 6 , a hood mounting structure according to an embodiment of the present invention includes an above-fender member 20, a hood 50, and a hood hinge 60. The above-fender member 20 is disposed along the longitudinal direction T of the vehicle body 10. The hood 50 is arranged in the front upper part of the vehicle body 10. The hood hinge 60 mounts the hood 50 to the above-fender member 20.

[0062] The fender 90 forming the vehicle body 10 is disposed below the hood 50.

[0063] The hood 50 may include a hood inner panel 52 and a hood outer panel 54 joined to the hood inner panel 52.

[0064] The hood hinge 60 includes an upper hinge arm 62 and a lower hinge arm 64. The upper hinge arm 62 is connected to the bottom of the hood 50. The lower hinge arm 64 is mounted on one side of the above-fender member 20. The hood hinge 60 may further include a hinge link 66 connecting the upper hinge arm 62 and the lower hinge arm 64.

[0065] A hood hinge receiving portion 22 for receiving the hood hinge 60 may be formed on the upper part of the above-fender member 20.

[0066] The component 20 above the fender may include an inner component 24 above the fender and an outer component 28 above the fender. The inner component 24 above the fender is arranged inside the vehicle body 10. The outer component 28 above the fender is coupled to the inner component 24 above the fender and has a hood hinge receiving portion 22 formed thereon.

[0067] The outer component 28 above the fender includes a flange portion 30, a side portion 32, and a connecting portion 34. The flange portion 30 is coupled to the inner component 24 above the fender. A hinge lower arm 64 is mounted on the side portion 32. The connecting portion 34 connects the flange portion 30 and the side portion 32, and the connecting portion 34 is formed to be recessed inwardly.

[0068] The inner component 24 above the fender includes an inner flange 26 above the fender, and the flange portion 30 of the outer component 28 above the fender may be coupled to the inner flange 26 above the fender.

[0069] The hood mounting structure according to an embodiment of the present invention may further include a partition 70 provided inside the component 20 above the fender.

[0070] That is, the partition 70 is provided in the connecting portion 34 of the outer component 28 above the fender, thereby improving the strength of the component 20 above the fender.

[0071] A hinge lower arm mounting portion 33 is formed on the side portion 32 so that the hinge lower arm 64 can be mounted thereon.

[0072] The connecting portion 34 may include an upper connecting portion 36 and a lower connecting portion 38. The upper connecting portion 36 is bent at the flange portion 30. The lower connecting portion 38 is bent from the upper connecting portion 36 and connected to the side portion 32. A space formed by the upper connecting portion 36 and the lower connecting portion 38 may be defined as the hood hinge receiving portion 22.

[0073] That is, as Figure 6 shown, the component 20 above the fender including the upper connecting portion 36, the lower connecting portion 38, the side portion 32, and the inner component 24 above the fender may have an "L" - shaped cross - section.

[0074] Since the cross - section of the component 20 above the fender is formed in an "L" shape, a predetermined distance between the upper portion of the connecting portion 34 and the lower portion of the hood 50 (i.e., the hood inner panel 52) may be ΔH1.

[0075] That is, as Figure 6 shown, a reference height H2 of the hinge upper arm 62 connected to the hood inner panel 52 is separated from a reference height H1 of the lower connecting portion 38 by a specific length ΔH1. This provides a space in which the hood 50 can deform in the case of a vehicle collision, which can reduce pedestrian injury.

[0076] The end of the engine hood 50 can extend to be lower than the connecting portion 34. That is to say, the engine hood 50 can be a hinged engine hood, and the height H3 at one end of its side surface is lower than the reference height H1 (ΔH2) of the lower connecting portion 38 below.

[0077] Reference Figures 4 to 6 , in the fender upper member 20, the installation direction towards the hinge upper arm 62 (which is connected to the lower part of the engine hood 50) can form the engagement tool holes 40 and 41.

[0078] The engagement tool holes 40 and 41 can be formed in multiple numbers.

[0079] An engine hood engagement portion 56 can be formed on the engine hood inner panel 52 of the engine hood 50, and the hinge upper arm 62 can be engaged with the engine hood engagement portion 56.

[0080] In the installation structure of a general hinged engine hood, since the engine hood interferes when covering, it is difficult to engage the hinge upper arm. If the hinge upper arm is engaged with the engine hood when the engine hood is opened, the vehicle quality may deteriorate due to gaps and flushness.

[0081] However, in an embodiment of the present invention, the engagement tool holes 40 and 41 are formed on the fender upper member 20 towards the engine hood engagement portion 56. Therefore, in the case where the engine hood 50 is covered, it can be engaged by inserting the engagement tool from the bottom of the vehicle body 10 into the engagement tool holes 40 and 41. In the case where the engine hood 50 is covered, the hinge upper arm 62 can be engaged with the engagement portion 56 to suppress gaps and flushness.

[0082] A partition 70 is provided between the engagement tool holes 40 and 41 inside the fender upper member 20 to improve the strength of the fender upper member 20. The strength of the fender upper member 20 may deteriorate due to the formation of the engagement tool holes 40 and 41 in the fender upper member 20, but the strength of the fender upper member 20 can be provided by the partition 70.

[0083] Figure 7 It is a partial side view of an engine hood installation structure according to an embodiment of the present invention.

[0084] The rear upper end portion 45 of the fender upper member 20 can be continuously connected to the front upper end portion 82 of the A-pillar upper member 80, and the A-pillar upper member 80 is arranged behind the fender upper member 20.

[0085] The connection between the fender upper member 20 and the A-pillar upper member 80 is continuously formed to facilitate the transmission of collision loads in the event of a collision and to suppress the deformation of the vehicle body 10.

[0086] As described above, in the hood mounting structure according to an embodiment of the present invention, the hinge lower arm is mounted on the side of the above-fender member to facilitate the bolt connection between the hinge and the vehicle body and to increase the strength of the hood. In addition, the possibility of interference between the hood hinge and the vehicle body or the hood can be reduced.

[0087] In the hood mounting structure according to an embodiment of the present invention, by forming the engagement tool hole in the above-fender member, the hood can be engaged while covering the hood, thereby facilitating the adjustment of the gap and flushness between the hood and the vehicle body.

[0088] In the hood mounting structure according to an embodiment of the present invention, the cross-sections of the above-fender member and the above-A-pillar member are continuously connected to improve the path during a collision and to enhance the response to a small overlap.

[0089] In the hood mounting structure according to an embodiment of the present invention, by providing a certain space between the above-fender member and the lower part of the hood, pedestrian injuries during a vehicle collision can be reduced.

[0090] In the hood mounting structure according to an embodiment of the present invention, the hood mounting work can be easily performed even in a short overhang vehicle having a short distance between the front shock absorber cover and the dash panel.

[0091] In the hood mounting structure according to an embodiment of the present invention, by arranging the hood hinge to the outermost side in the vehicle width direction of a vehicle to which a clamshell hood is applied, sufficient hood strength can be provided.

[0092] In the hood mounting structure according to an embodiment of the present invention, since the assembly can be performed while the hood is closed, it is easy to adjust the simple differences between the hood and the fender and between the hood and the bumper.

[0093] Although the present invention has been described with reference to presently considered to be practical exemplary embodiments, it should be understood that the present invention is not limited to the disclosed embodiments.
