Description

[Technical field]

[0001] The present invention relates to a vehicle front structure. [Background technology]

[0002] For example, there is known a structure in which electrical components such as an airbag sensor are attached around a lamp attached to the front of a vehicle, as disclosed in Patent Document 1. In the structure disclosed in Patent Document 1, when an impact load acts on the front of the vehicle due to a frontal collision, the headlamp is configured to rotate relatively rearward with respect to the vehicle body, with a predetermined position as the center of rotation, and at least a part of the airbag sensor is disposed within the rotation trajectory of the lamp at the inner end in the vehicle width direction.

[0003] In this example, an interference portion is provided to limit the relative rotation of the lamp. The interference portion is configured to interfere with a part of the lamp and limit the relative rotation of the lamp before the inner end of the lamp interferes with the airbag sensor during the relative rotation of the lamp. By providing the interference portion, it is possible to prevent the lamp from interfering with the airbag sensor in the early stage of a collision even if the sensor is disposed within the rotation trajectory of the lamp. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4525655 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above example, the lamp is configured to rotate to a predetermined position in the event of a frontal collision, but depending on the vehicle specifications, the lamp may move parallel to the rear of the vehicle in the event of a frontal collision. In other words, if the lamp moves backward, there is a possibility that the lamp may come into contact with electrical components such as sensors and harnesses arranged around the lamp.

[0006] For example, if the airbag sensor is damaged by contact with the lamp, it may prevent the airbag from operating properly. Therefore, the structure of the above example has room for improvement in order to prevent the electrical components located behind the lamp at the front of the vehicle from coming into contact with the lamp during a frontal collision.

[0007] The present invention has been made to solve the above-mentioned problems, and its object is to provide a vehicle front structure that can prevent electrical components located at the rear of a lamp at the front of the vehicle from coming into contact with the lamp in the event of a frontal collision. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention provides a vehicle front structure comprising: a side member disposed on an outer side in the vehicle width direction and extending in the vehicle front-rear direction; a hood lock member disposed at the front of the vehicle and extending in the vehicle width direction; a lamp support member that connects the hood lock member and the side member, that is disposed on the vehicle rear side of a lamp device at the front of the vehicle and supports the lamp device; and an electrical component disposed on the vehicle rear side of the lamp device. The vehicle front structure further comprises a protective member attached to the lamp support member, and an electrical component mounting portion configured to surround the electrical component is provided at a portion where the lamp support member, the protective member, and the hood lock member are connected. Effect of the Invention

[0009] According to the present invention, it is possible to prevent electrical components arranged on the rear side of a lamp in the front of the vehicle from coming into contact with the lamp during a frontal collision. [Brief description of the drawings]

[0011] Hereinafter, an embodiment of a vehicle front structure according to the present invention will be described with reference to the drawings (FIGS. 1 to 9). In the drawings, the direction of the arrow Fr indicates the front in the vehicle longitudinal direction. In the description of the embodiment, the "front (front end) and rear (rear end)" correspond to the front and rear in the vehicle longitudinal direction. Additionally, the arrows R and L indicate the right and left sides when an occupant looks forward of the vehicle. Additionally, the arrow U indicates the upward direction in the vehicle vertical direction.

[0012] As shown in Figs. 1 to 6, the vehicle front structure of this embodiment includes a side member 4 extending in the vehicle longitudinal direction, a hood lock member 20 disposed at the front of the vehicle and extending in the vehicle width direction, a lamp support member 10 supporting a lamp device 9, an electric component 1, a protective member 30 protecting the electric component 1, a reinforcement 40, a brace 50, and a lamp bracket 60. As shown in Figs. 2 and 3, the electric component 1 of this embodiment is, for example, an airbag sensor, and is disposed on the vehicle rear side of the lamp device 9. At least one harness (not shown) for transmitting an electric signal is connected to the airbag sensor. The airbag sensor detects vibrations generated when an impact load acts on the vehicle, and transmits information related to the vibrations to an airbag device (not shown). In this embodiment, as shown in Figs. 5 and 6, an electric component attachment portion 2 configured to surround the electric component 1 is provided at a portion where the lamp support member 10, the protective member 30, and the hood lock member 20 are connected. Each member will be described below.

[0013] As shown in Figures 4 and 5, the side members 4 are disposed on both outer sides in the vehicle width direction at the front of the vehicle and extend in the vehicle front-rear direction. A power room in which a drive device such as an engine or a motor is disposed is disposed at the front of the vehicle, and the side members 4 are disposed on both sides of the power room in the vehicle width direction. The side members 4 are formed of a metal material and are highly rigid members that constitute the vehicle body framework. A lamp support member 10 is connected to the front of the side member 4 via members such as an extension panel 5 and an end plate 6, and a side portion of a hood lock member 20 in the vehicle width direction is connected to an upper portion of the lamp support member 10.

[0014] Here, the lamp support member 10 will be described. As shown in Figures 4 and 5, the lamp support member 10 is a member extending in the vertical direction of the vehicle, and connects the hood lock member 20 and the side member 4. In this example, an extension plate made of, for example, a metal material is joined to the front end of the side member 4, and the lower part of the lamp support member 10 is joined to the upper part of the extension plate by, for example, spot welding or the like.

[0015] As shown in FIG. 4 and FIG. 6, the lamp support member 10 has a first outer surface portion 11, a first front wall surface portion 12, and a first rear wall surface portion 13. In this embodiment, the first outer surface portion 11, the first front wall surface portion 12, and the first rear wall surface portion 13 are integrally formed. The first outer surface portion 11 extends in the vehicle vertical direction and faces the outside in the vehicle width direction. An upper portion of the first outer surface portion 11 is joined to the reinforcement 40. An electric part 1 is attached to the upper portion of the first outer surface portion 11. Furthermore, a brace 50 is joined to a middle portion of the first outer surface portion 11 in the vehicle vertical direction. The joining between the first outer surface portion 11 and the brace 50 will be described later. Also, as shown in FIG. 4, a lower portion of the first outer surface portion 11 is joined to, for example, an extension panel 5 by spot welding or the like.

[0016] As shown in Figs. 4, 6 and 8, the first front wall portion 12 protrudes from the front end of the first outer side surface portion 11 inward in the vehicle width direction and extends in the vehicle vertical direction. The first front wall portion 12 faces the front of the vehicle and has a vertically elongated flat surface extending in the vehicle vertical direction. A through hole 12d is formed in the upper portion of the first front wall portion 12, through which a fastening member such as a bolt can pass. A hood lock member 20 and a reinforcement 40 are joined to the upper portion of the first front wall portion 12. A protective member 30 is joined to the middle portion of the first front wall portion 12 in the vehicle vertical direction, and a lamp bracket 60 is joined to the lower portion. The joining state of each member will be described later.

[0017] The first rear wall portion 13 protrudes outward in the vehicle width direction from the rear end of the first outer side surface portion 11 and extends in the vehicle vertical direction. The first rear wall portion 13 has a flat surface that faces the rear of the vehicle and extends in the vehicle vertical direction. The upper end of the first rear wall portion 13 extends horizontally from the upper end of the first outer side surface portion 11 outward in the vehicle width direction.

[0018] The outer end of the first rear wall surface portion 13 has a first inclined portion 13a that inclines downward from the outer end of the upper end in the vehicle width direction toward the outer side in the vehicle width direction, a second inclined portion 13b that inclines downward from the outer end of the first inclined portion 13a toward the outer side, and a third inclined portion 13c that inclines downward from the outer end of the second inclined portion 13b toward the outer side, and has an outer end portion that extends downward from the lower end of the third inclined portion 13c. The inclination angles of the first inclined portion 13a, the second inclined portion 13b, and the third inclined portion 13c are gradually increased in this order.

[0019] As shown in Fig. 4 and Fig. 6, the inclination angle indicates an angle formed by each of the inclined portions 13a, 13b, and 13c and a horizontal line (not shown). By providing the inclined portions 13a, 13b, and 13c in this manner, the length of the first rear wall portion 13 in the vehicle width direction gradually becomes shorter toward the upper part of the vehicle. In addition, a plurality of holes are provided in the outer side of the first rear wall portion 13 in the vehicle width direction. The holes include, for example, through holes through which a harness passes and mounting holes to which a clip for fixing the harness is attached.

[0020] 7 and 8, a reinforcement 40 is joined to an upper portion of the first rear wall portion 13. In this example, the upper portion of the first rear wall portion 13 is joined to the hood lock member 20 via the reinforcement 40. A protective member 30 is joined to a middle portion of the first rear wall portion 13 in the vertical direction of the vehicle. A lower portion of the first rear wall portion 13 is joined to the extension panel 5. A front end of a side member 4 is disposed below the first rear wall portion 13 at the outer side in the vehicle width direction.

[0021] Next, the hood lock member 20 will be described. As shown in Fig. 4 to Fig. 6, the hood lock member 20 is a metal member arranged in the upper part of the vehicle at the front part of the vehicle, extending in the vehicle width direction, and is a highly rigid member that supports the vehicle hood, etc. The outer part of the hood lock member 20 in the vehicle width direction is arranged above the front end of the side member 4 in the vehicle up-down direction, and is arranged inward of the front end of the side member 4 in the vehicle width direction.

[0022] As shown in Figs. 4 to 8, the hood lock member 20 has a top surface portion 21, a second front wall surface portion 22, and a second rear wall surface portion 23. In this embodiment, the top surface portion 21, the second front wall surface portion 22, and the second rear wall surface portion 23 are integrally formed. The top surface portion 21 faces upward in the vehicle and extends in the vehicle width direction. The upper surface side of the top surface portion 21 has a horizontally elongated flat surface facing upward in the vehicle.

[0023] As shown in FIG. 7, the second front wall surface portion 22 protrudes from the front end of the top surface portion 21 downwardly of the vehicle and extends in the vehicle width direction. The second front wall surface portion 22 has a flat surface facing the front of the vehicle. Three through holes 22d, 22e are formed in the outer portion of the second front wall surface portion 22 in the vehicle width direction. In this example, there are two outer holes 22e and one inner hole 22d. The two outer holes 22e are arranged at intervals in the vertical direction along the outer end of the second front wall surface portion 22. The inner hole 22d is arranged at an interval on the inner side of the outer hole 22e in the vehicle width direction. In addition, in the vehicle vertical direction, the inner hole 22d is arranged between the upper and lower outer holes 22e.

[0024] The second rear wall surface portion 23 protrudes downward from the rear end of the top surface portion 21 and extends in the vehicle width direction. The second rear wall surface portion 23 has a flat surface facing the rear of the vehicle. The second rear wall surface portion 23 is disposed on the rear side of the second front wall surface portion 22 with a gap therebetween.

[0025] 7 to 9, the second front wall portion 22 is provided with a front flange 22a that protrudes forward from the lower end of the second front wall portion 22 and extends in the vehicle width direction, and the second rear wall portion 23 is provided with a rear flange 23a that protrudes rearward from the lower end of the second rear wall portion 23 and extends in the vehicle width direction, and a plate-shaped lower panel 25 (lower member) extending in the vehicle width direction is joined to the lower part of the hood lock member 20. As shown in FIG. 9, the front part of the lower panel 25 is joined to the front flange 22a, and the rear part of the lower panel 25 is joined to the rear flange 23a. The position of the lower panel 25 in the vehicle vertical direction corresponds to the position of the electric component 1 in the vehicle vertical direction. In this example, the plate-shaped lower panel 25 is arranged, but for example, the lower panel 25 may be replaced with a plurality of rod-shaped (plurality of elongated plate-shaped) members extending in the vehicle width direction.

[0026] The hood lock member 20 and the lower panel 25 form a closed cross-sectional structure. This improves the rigidity of the hood lock member 20. Furthermore, the outer end of the lower panel 25 in the vehicle width direction is disposed inside the outer end of the hood lock member 20 in the vehicle width direction. Therefore, the hood lock member 20 located outside the lower panel 25 in the vehicle width direction has a U-shaped open cross-sectional structure that opens toward the bottom of the vehicle formed by the top surface portion 21, the second front wall surface portion 22, and the second rear wall surface portion 23. The above-mentioned electric component attachment portion 2 is provided in the open cross-sectional structure. Here, in this embodiment, the lower portion of the closed cross-sectional structure of the hood lock member 20 (the portion where the lower panel 25 is disposed) is disposed next to the electric component 1 in the vehicle width direction. This makes it possible to provide a structure in which the electric component 1 is less likely to be crushed.

[0027] Next, the protective member 30 will be described. As shown in Figs. 4 to 6, the protective member 30 is a member arranged so as to cover the electric component 1 from the outer side in the vehicle width direction. As described above, the electric component attachment portion 2 is provided at a portion where the protective member 30, the lamp support member 10, and the hood lock member 20 are connected. In this example, the electric component attachment portion 2 is configured by joining the protective member 30 to the above-mentioned open cross-sectional structure of the hood lock member 20.

[0028] Even if the lamp device 9 moves toward the rear of the vehicle due to an impact load such as a frontal collision, the provision of the protective member 30 makes it possible to prevent the electrical component 1 and the harness connected thereto from being crushed.

[0029] The impact load generated during a frontal collision is easily transmitted to the side member 4 and the hood lock member 20. In this embodiment, the airbag sensor (electrical component 1) is attached to the lamp support member 10 that connects the side member 4 and the hood lock member 20, so that the airbag sensor can obtain more accurate information about vibrations generated during an impact. As a result, the airbag device can be appropriately activated.

[0030] Here, the protective member 30 will be described in detail. As shown in Fig. 4 to Fig. 6, the protective member 30 has a second outer side surface portion 31, a third front wall surface portion 32, and a third rear wall surface portion 33. In this embodiment, the second outer side surface portion 31, the third front wall surface portion 32, and the third rear wall surface portion 33 are integrally formed.

[0031] The second outer surface portion 31 extends in the vehicle up-down direction, and is disposed on the vehicle width direction outer side of the first outer surface portion 11 with a gap therebetween. The second outer surface portion 31 is also disposed on the outer side of the vehicle width direction outer end of the electrical component 1 with a gap therebetween. Furthermore, the upper end of the second outer surface portion 31 is located above the upper end of the electrical component 1, and the lower end of the second outer surface portion 31 is located below the lower end of the electrical component 1.

[0032] The third front wall surface portion 32 protrudes from the front end of the second outer side surface portion 31 toward the inside in the vehicle width direction and is joined to the first front wall surface portion 12. The third front wall surface portion 32 has a vertical wall portion 32a and a flange portion 32b. The vertical wall portion 32a has a substantially rectangular shape extending in the vehicle up-down direction and is arranged on the vehicle front side of the electric component 1 with a gap therebetween. The outer end of the vertical wall portion 32a in the vehicle width direction and the front end of the second outer side surface portion 31 form a corner portion. In this example, the boundary between the vertical wall portion 32a and the second outer side surface portion 31 is the ridge line of the corner portion. The flange portion 32b is a portion that extends further toward the inside in the vehicle width direction from the inner end of the vertical wall portion 32a in the vehicle width direction and faces the front of the vehicle. The flange portion 32b is joined to the first front wall surface portion 12 of the lamp support member 10.

[0033] A through hole is formed in the lower part of the flange portion 32b, through which a fastening member such as a bolt can be inserted. Furthermore, a through hole is formed in the first front wall surface portion 12 at a position corresponding to the through hole of the flange portion 32b. The flange portion 32b and the first front wall surface portion 12 are fastened together by inserting a fastening member such as a bolt through these through holes. The flange portion 32b and the first front wall surface portion 12 may be joined together by spot welding or the like.

[0034] The third rear wall surface portion 33 protrudes outward in the vehicle width direction from the rear end of the second outer side surface portion 31 and is joined to the first rear wall surface portion 13. The outer end of the second rear wall surface portion 23 inclines downward in the vehicle width direction as it moves outward in the vehicle width direction. A through hole is formed in the lower part of the third rear wall surface portion 33, through which a fastening member such as a bolt can be inserted. In addition, a through hole is formed in the first rear wall surface portion 13 at a position corresponding to the through hole of the third rear wall surface portion 33. The third rear wall surface portion 33 and the first rear wall surface portion 13 are fastened to each other by inserting a fastening member such as a bolt through these through holes. These may be joined by spot welding or the like.

[0035] Next, the reinforcement 40 will be described. As shown in Fig. 7 and Fig. 8, the reinforcement 40 is a member joined to the open cross-sectional structure of the hood lock member 20, and in this embodiment, constitutes a part of the electric component mounting portion 2. The reinforcement 40 is joined to the inside in the vehicle width direction of the first outer side surface portion 11, and extends in the vehicle up-down direction. An upper portion of the reinforcement 40 is joined to the top surface portion 21. The reinforcement 40 will be described in detail below.

[0036] The reinforcement 40 of this embodiment has a vertical wall portion 41, an upper surface portion 42, a front vertical flange portion 43, and a rear vertical flange portion 44, which are integrally formed. The vertical wall portion 41 extends in the vehicle up-down direction and faces the outside in the vehicle width direction. The vertical wall portion 41 is joined to the first outer side surface portion 11 of the lamp support member 10. In this example, the electric component 1 is fastened by a bolt at a position where the first outer side surface portion 11 and the vertical wall portion 41 overlap. This makes it possible to fix the electric component 1 at a position with high surface rigidity. That is, the rigidity of the electric component mounting portion 2 can be improved. In addition, the upper surface portion 42 is curved from the upper portion of the vertical wall portion 41 toward the inside in the vehicle width direction and protrudes toward the inside in the vehicle width direction. A through hole is provided in the upper surface portion 42, and the upper surface portion 42 is fastened to the top surface portion 21 of the hood lock member 20 by a bolt or the like.

[0037] The front vertical flange portion 43 is a portion that protrudes from the front end of the vertical wall portion 41 toward the inside in the vehicle width direction and extends in the vehicle up-down direction. The front vertical flange portion 43, the first front wall portion 12, and the second front wall portion 22 are fastened together in a three-layered state by fastening members such as bolts. In this example, the through hole 43d of the front vertical flange portion 43, the through hole 12d of the first front wall portion 12, and the inner hole 22d of the second front wall portion 22 are arranged so as to communicate with each other, and the three layers are fastened together by inserting fastening members (FIGS. 7 and 8). The rear vertical flange portion 44 is a portion that protrudes from the rear end of the vertical wall portion 41 toward the outside in the vehicle width direction and extends in the vehicle up-down direction. Although not illustrated, the rear vertical flange portion 44, the first rear wall portion 13, and the second rear wall portion 23 may be fastened together in a three-layered state by fastening members such as bolts. By providing the reinforcement 40, it is possible to increase the rigidity of the portion surrounding the electric component 1, that is, the electric component mounting portion 2.

[0038] In this embodiment, as described above, the protective member 30 is joined to the first front wall surface portion 12 and the first rear wall surface portion 13. This makes it possible to achieve a structure in which the electrical components 1 and the harness are less likely to be crushed even when subjected to an impact load. Furthermore, by disposing the electrical components 1 between the first front wall surface portion 12 and the first rear wall surface portion 13, it is possible to suppress crushing of the electrical components 1 and the harness when the lamp device 9 is moved (reversed) toward the rear of the vehicle.

[0039] Furthermore, in this embodiment, the first front wall surface portion 12, the second front wall surface portion 22, and the electric component 1 are arranged to overlap each other when viewed from the front of the vehicle. As a result, the hood lock member 20 is also configured to surround the electric component 1, so that the rigidity of the electric component mounting portion 2 can be further improved.

[0040] Furthermore, in this embodiment, the first outer surface portion 11, the second rear wall surface portion 23, the second outer surface portion 31, and the third front wall surface portion 32 form a closed cross-sectional structure in which the electric component 1 is disposed inside. This makes it possible to further increase the rigidity of the electric component mounting portion 2. Also, in this embodiment, the first front wall surface portion 12, the second front wall surface portion 22, and the third front wall surface portion 32 are joined in three layers at the front of the closed cross-sectional structure, so that when the lamp device 9 moves rearward due to a frontal collision or the like, the protection performance of the electric component 1 is further improved.

[0041] 5 and 6, the present embodiment includes a brace 50 disposed on the vehicle lower side of the protective member 30. The brace 50 includes a substantially rectangular main body 51 facing upward toward the vehicle, an inner flange 52 protruding upward from the inner end of the main body 51 in the vehicle width direction, and a rear flange (not shown) protruding downward from the rear end of the main body 51. The upper surface of the main body 51 is inclined toward the vehicle lower side as it moves toward the outer side in the vehicle width direction. The electrical component mounting portion 2 constituted by the protective member 30 and the like is constituted by a wall surface extending in the vertical direction.

[0042] By providing the brace 50 having an inclined surface on the lower side of the electric component mounting portion 2, it is possible to increase the rigidity in a direction different from the wall surface constituting the electric component mounting portion 2. As a result, it is possible to increase the rigidity around the electric component mounting portion 2. It is also possible to facilitate the installation of the harness connected to the electric component 1.

[0043] Moreover, the inner flange portion 52 is joined to the first outer side surface portion 11 by spot welding. The rear flange portion is joined to the first rear wall surface portion 13 by spot welding. The inner flange portion 52 and the rear flange portion, which are perpendicular to each other, are joined to the lamp support member 10, thereby improving the rigidity of the lamp support member 10 below the protective member 30. This makes it possible to make the electric component 1 in the electric component mounting portion 2 less likely to be crushed.

[0044] Furthermore, in this embodiment, a lamp bracket 60 is joined to the front portion of the brace 50. The lamp bracket 60 is a member for fixing the lamp device 9, and has a predetermined rigidity. The lamp bracket 60 has a flat portion 61 extending from the front portion of the brace 50 toward the front of the vehicle, and a front wall portion 62 extending from the front end of the flat portion 61 toward the bottom of the vehicle. A rear flange portion 65 protruding upward is provided at the rear end of the flat portion 61. The rear flange portion 65 is joined to the front portion of the brace 50.

[0045] 2 to 6, the lamp bracket 60 has a side wall portion 63 provided on the inside of the front wall portion 62, and an inner flange portion 64 provided on the inner end of the side wall portion 63 and joined to the first front wall surface portion 12. The inner end of the flat portion 61 is connected to the upper end of the side wall portion 63. The front wall portion 62 is provided with a through hole or the like for mounting the lamp device 9.

[0046] The brace 50 and the lamp bracket 60 are joined to the lamp support member 10, thereby increasing the rigidity of the lamp support member 10. For example, the brace 50 is joined to the first outer side surface portion 11, the lamp bracket 60 is joined to the first front wall surface portion 12, and further, the lamp bracket 60 and the brace 50 are joined to each other, thereby forming a joining structure in which a plurality of members are joined together.

[0047] This increases the rigidity of the lamp support member 10. In addition, since the joint structure is disposed below the electric component mounting portion 2, the joint structure can also contribute to improving the rigidity of the electric component mounting portion 2. Furthermore, even if the amount of rearward movement during a collision is large, since the lamp bracket 60 has the flat portion 61 and the front wall portion 62 that are disposed forward of the electric component mounting portion 2, it is possible to protect the electric component mounting portion 2 from impact loads.

[0048] The description of the present embodiment is merely an example for explaining the present invention, and does not limit the invention described in the claims. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0049] In this embodiment, for example, the protective member 30 may have a structure having a U-shaped cross section. In this case, the third rear wall surface portion 33 may be configured to extend from the rear end of the second outer side surface portion 31 toward the inside in the vehicle width direction.
