Summary of the Invention

Problems to be Solved by the Invention

[0004] In current vehicles, there is a demand for improved vibration performance so that vibrations caused by the driving of a power unit such as an engine can be suppressed. In this regard, since the side member is a hollow member that is long in the vehicle longitudinal direction, it is known that it is likely to vibrate in the vehicle width direction due to the driving of an engine or the like within the range where an engine mount or the like is attached. The vibration of the side member in the vehicle width direction is likely to be transmitted to a nearby fender apron panel or the like, which not only affects the vibration performance of the vehicle but may also affect the quietness inside the vehicle cabin.

[0005] In view of such problems, an object of the present invention is to provide a vehicle front structure capable of efficiently suppressing vibrations caused by a power unit.

Means for Solving the Problems

[0006] In order to solve the above problems, a typical configuration of the vehicle front structure according to the present invention is a vehicle front structure provided in a power unit mounting room at the front of a vehicle to support a predetermined power unit. In this vehicle front structure, there are a side member extending in the vehicle longitudinal direction at a side portion of the power unit mounting room, a first bracket installed above the side member, a second bracket installed behind the first bracket above the side member, a mount member that is passed between the first bracket and the second bracket to support the power unit, a first reinforcing member provided in a range below the first bracket inside the side member, and a second reinforcing member provided in a range below the second bracket inside the side member. Each of the first reinforcing member and the second reinforcing member is joined to at least the upper surface portion, the lower surface portion, and the side surface portion on the inner side in the vehicle width direction of the side member, which is characterized in that.

Advantages of the Invention

[0007] According to the present invention, it becomes possible to provide a vehicle front structure capable of efficiently suppressing vibrations caused by the power unit.

Embodiments for Carrying Out the Invention

[0009] The vehicle front structure according to an embodiment of the present invention is a vehicle front structure provided in a power unit mounting room at the front of a vehicle for supporting a predetermined power unit. In this vehicle front structure, there are a side member extending in the vehicle front-rear direction at a side portion of the power unit mounting room, a first bracket installed above the side member, a second bracket installed behind the first bracket above the side member, a mount member passed between the first bracket and the second bracket for supporting the power unit, a first reinforcing member provided in a range below the first bracket inside the side member, and a second reinforcing member provided in a range below the second bracket inside the side member. Each of the first reinforcing member and the second reinforcing member is joined to at least the upper surface portion, the lower surface portion, and the side surface portion on the inner side in the vehicle width direction of the side member.

[0010] According to the above configuration, the rigidity of the side member in a range where it is likely to receive a load from the power unit can be increased by the first reinforcing member and the second reinforcing member. In particular, the first reinforcing member and the second reinforcing member are provided in a range overlapping below the first bracket and the second bracket respectively of the side member, preventing deformation of the cross-section of the side member in this range. Therefore, according to the above configuration, it is possible to efficiently suppress vibrations caused by the power unit.

[0011] The vehicle front structure further includes a front fixing portion provided on the top surface of the first bracket to which the mount member is fixed, and a rear fixing portion provided on the top surface of the second bracket to which the mount member is fixed. The first reinforcing member and the second reinforcing member may be provided in a range between the front fixing portion and the rear fixing portion in the longitudinal direction of the side member.

[0012] Among the side members, the range between the front fixing point of the first bracket and the rear fixing point of the second bracket is likely to be loaded with the load from the power unit through the mounting member. In the above configuration, by providing the first reinforcing member and the second reinforcing member in the said range, it becomes possible to efficiently improve the rigidity of the range liable to receive the load from the power unit.

[0013] The said first bracket and second bracket are each in a shape bulging upward from the side member, the first reinforcing member may be provided on the extension of the rear wall portion of the first bracket, and the second reinforcing member may be provided on the extension of the front wall portion of the second bracket.

[0014] According to the above configuration, by providing the first reinforcing member and the second reinforcing member on the extensions of the wall portions of the first bracket and the second bracket respectively, these first reinforcing member and second reinforcing member can efficiently absorb the load from the power unit input to the side member via the first bracket and the second bracket.

[0015] The vehicle front structure further includes a strut tower in which the suspension of the front wheels of the vehicle is housed, and a fender apron panel extending forward of the vehicle from the strut tower. The side member is provided along the lower part of the fender apron panel and the strut tower. The fender apron panel has an apron side wall portion extending upward from the side member, an apron flange bent and extending outward in the vehicle width direction from the upper end of the apron side wall portion, and an apron bulging region in which a predetermined range along the apron flange in the apron side wall portion bulges inward in the vehicle width direction. The vehicle front structure may further include a patch member on which the mounting member is fixed and which is installed so as to straddle the apron flange and the apron bulging region of the fender apron panel.

[0016] According to the above configuration, it becomes possible to further disperse the load from the power unit by using the patch member and the fender apron panel. In particular, among the fender aprons, the locations where the apron flange and the apron bulging region are provided have a three-dimensionally changing shape, a large second moment of area, and are difficult to bend. Therefore, by installing the patch member so as to straddle the apron flange and the apron bulging region of the fender apron panel, it becomes possible to disperse the load transmitted from the power unit via the mount member to the locations of the fender apron panel that are highly rigid and difficult to bend.

[0017] The above patch member has an upper fixing portion to which the mount member is fixed, and the upper fixing portion may be provided in a range between the front fixing portion and the rear fixing portion in the vehicle front-rear direction.

[0018] In the range between the front fixing portion and the rear fixing portion, the first reinforcing member and the second reinforcing member are present and the rigidity is improved. Therefore, by also providing the upper fixing portion in the said range, it becomes possible to more efficiently absorb the load from the power unit.

The side member 102 is provided along the lower portions of the fender apron panel 104 and the strut tower 106, and supports a power unit (not shown) from below via a mount member 112 or the like.

[0023] The mount member 112 is a member that supports a power unit such as an engine or a motor, which is a power source of the vehicle, and can be implemented as, for example, an engine mount or a motor mount. The mount member 112 is delivered to the upper sides of the first bracket 114 and the second bracket 116 and is installed on the side member 102 via the first bracket 114 or the like. Further, the side of the mount member 112 is joined to the fender apron panel 104 via a patch member 118.

[0024] The first bracket 114 and the second bracket 116 are members that support the mount member 112, and each has a shape that bulges upward from the side member 102. The first bracket 114 and the second bracket 116 are joined from the side surface portion 102b to the upper surface portion 102a of the side member 102 and to the fender apron panel 104.

[0025] The first bracket 114 is installed above the side member 102 and fixes the front side of the mount member 112. The second bracket 116 is installed behind the first bracket 114 on the upper side of the side member 102 and fixes the rear side of the mount member 112.

[0026] Figure 1(b) is a view of the state where the mount member 112 in Figure 1(a) is removed.

[0027] The strut tower 106 is a member that houses the suspension of the front wheels of the vehicle. Above the strut tower 106, a cowl upper panel 108 is provided so as to extend in the vehicle width direction, and a cowl side member 110 is provided outside the strut tower 106 in the vehicle width direction.

[0028] The fender apron panel 104 is a member that partitions the power unit mounting room and the vicinity of the front wheels, and is provided so as to extend forward from the strut tower 106. The fender apron panel 104 has the above-described patch member 118 attached thereto, and the mount member 112 is fixed via the patch member 118.

[0029] Figure 2 is a view showing the front vehicle structure 100 in Figure 1(b) as viewed from the inside in the vehicle width direction.

[0030] In the front vehicle structure 100, as fixing portions of the mount member 112, a total of three fixing portions, namely, a front fixing portion 120, a rear fixing portion 122, and an upper fixing portion 124, are provided. These fixing portions can be implemented as, for example, bolt fastening holes.

[0031] The front fixing portion 120 is provided on the top surface of the first bracket 114, and the lower part of the front side of the mount member 112 is fixed thereto. The rear fixing portion 122 is provided on the top surface of the second bracket 116, and the lower part of the rear side of the mount member 112 is fixed thereto. The upper fixing portion 124 is provided near the center of the patch member 118, and the upper side portion of the mount member 112 is fixed thereto.

[0032] In this embodiment, a first reinforcing member 126 and a second reinforcing member 128 are provided inside the side member 102 as reinforcing members.

[0033] The first reinforcing member 126 is provided in the range below the first bracket 114 inside the side member 102. The first reinforcing member 126, the side member 102, and the first bracket 114 are arranged so as to overlap at the same location and are joined to each other by spot welding or the like with the same dotting.

[0034] The second reinforcing member 128 is provided in the range below the second bracket 116 inside the side member 102. The second reinforcing member 128, the side member 102, and the second bracket 116 are arranged so as to overlap at the same location and are joined by spot welding or the like with the same dotting.

[0035] FIG. 3 is an enlarged view showing the first reinforcing member 126 of FIG. 2. FIG. 3(a) is a perspective view of the first reinforcing member 126 of FIG. 2 as viewed obliquely upward from the upper left side in the vehicle front direction. The first reinforcing member 126 and the second reinforcing member 128 (see FIG. 2) have a similar symmetrical configuration, and the shape and function of the first reinforcing member 126 described below can also be applied to the second reinforcing member 128.

[0036] The first reinforcing member 126 is shaped to be installed so as to partition the inside of the side member 102 (see Fig. 4(a)). The main wall portion 130, which is the main part of the first reinforcing member 126, is shaped to be disposed inside the closed cross-section E1 of the side member 102. A flange that contacts and joins to the inner wall of the side member 102 is provided around the main wall portion 130.

[0037] The upper flange 132a bends and extends from the upper edge of the main wall portion 130 and contacts and joins to the inner surface of the upper surface portion 102a of the side member 102 (see Fig. 4(a)). The side flange 132b bends and extends from the inner edge in the vehicle width direction of the main wall portion 130 and contacts and joins to the inner surface of the side surface portion 102b on the inner side in the vehicle width direction of the side member 102.

[0038] Fig. 3(b) is a perspective view of the first reinforcing member 126 in Fig. 3(b) viewed from the opposite side. The lower flange 132c bends and extends from the lower edge of the main wall portion 130 and contacts and joins to the inner surface of the lower surface portion 102c of the side member 102 (see Fig. 4(a)).

[0039] In this embodiment, the upper flange 132a, the side flange 132b, and the lower flange 132c have a continuous configuration, but they may be implemented in a shape that is segmented at various locations. That is, the shape of the first reinforcing member 126 is not limited to a configuration in which it is continuously joined across the upper surface portion 102a, the side surface portion 102b, and the lower surface portion 102c of the side member 102. As long as the shape of the first reinforcing member 126 can be joined to at least a part of each of the upper surface portion 102a, the side surface portion 102b, and the lower surface portion 102c, it is possible to suppress cross-sectional deformation of the side member 102.

[0040] Also, it is also possible to provide a side flange on the first reinforcing member 126 that contacts the inner surface of the side surface portion 102d on the outer side in the vehicle width direction of the side member 102 (see Fig. 4(a)) at the inner edge in the vehicle width direction of the main wall portion 130 as a flange paired with the side flange 132b.

[0041] FIG. 4 is a sectional view of the vehicle front structure 100 in FIG. 2. FIG. 4(a) is a sectional view taken along line A-A of the vehicle front structure 100 in FIG. 2. The shape and function of the configuration combining the first bracket 114 and the first reinforcing member 126 described with reference to FIG. 4 can also be applied to the configuration combining the second bracket 116 and the second reinforcing member 128 in FIG. 2.

[0042] As described above, within the range below the first bracket 114, a first reinforcing member 126 is provided inside the side member 102. By providing the first reinforcing member 126 inside the side member 102, the rigidity of the side member 102 can be increased, thereby suppressing deformation and vibration of the cross-section of the side member 102.

[0043] FIG. 4(b) is a sectional view taken along line B-B of the vehicle front structure 100 in FIG. 2. The first reinforcing member 126 is joined to the side member 102 and the first bracket 114 by spot welding or the like.

[0044] The first reinforcing member 126 is joined to the upper surface portion 102a, the side surface portion 102b, and the lower surface portion 102c on the inner surface side of the side member 102 by an upper flange 132a, a side flange 132b, and a lower flange 132c. The upper flange 132a and the side flange 132b are also joined to the first bracket 114 via the side member 102.

[0045] The above-mentioned first reinforcing member 126 can efficiently absorb the load applied to the side member 102 from the power unit via the mount member 112 (see FIG. 1(a)) and the first bracket 114.

[0046] According to the above configuration, the rigidity of the side member 102 in the range where it is likely to receive a load from the power unit can be increased by the first reinforcing member 126 and the second reinforcing member 128. In particular, since the first reinforcing member 126 and the second reinforcing member 128 are provided in a range overlapping below the first bracket 114 and the second bracket 116 respectively, it is possible to efficiently suppress vibrations caused by the power unit.

[0047] As shown in FIG. 1(b), since the side member 102 is long in the vehicle front-rear direction, it tends to vibrate in the vehicle width direction due to the load from the power unit. In this regard, in the present embodiment, by providing the first reinforcing member 126 and the second reinforcing member 128 directly below the first bracket 114 and the second bracket 116, it is difficult to deform the closed cross-section E1 of the side member 102, and it is difficult for the side member 102 to sway in the vehicle width direction, making it possible to efficiently suppress the generation of vibrations.

[0048] As shown in FIG. 4(a), due to the interposition of the first reinforcing member 126, the upper surface portion 102a and the lower surface portion 102c of the side member 102, and the side surface portion 102b and the side surface portion 102d are difficult to deform in a direction approaching each other. That is, the closed cross-section E1 of the side member 102 is difficult to deform. Therefore, according to the present embodiment, the side member 102 can be made strong against vertical and horizontal loads, and it is possible to preferably suppress the generation of vibrations and abnormal noises caused by the power unit.

[0049] Referring to FIG. 2 again. The first reinforcing member 126 and the second reinforcing member 128 are provided within a range D1 between the front fixing portion 120 and the rear fixing portion 122 in the longitudinal direction of the side member 102.

[0050] The first reinforcing member 126 is arranged with respect to the front fixing portion 120 of the first bracket 114 such that the main wall portion 130 is positioned rearward. Also, the second reinforcing member 128 is arranged with respect to the rear fixing portion 122 of the second bracket such that the main wall portion 134 is positioned forward. At this time, the first reinforcing member 126 and the second reinforcing member 128 are installed such that the main wall portions 130 and 134 are vertical.

[0051] Among the side members 102, in the range D1 between the front fixing portion 120 of the first bracket 114 and the rear fixing portion 122 of the second bracket 116, a load from the power unit is likely to be applied through the mount member 112 (see Fig. 1(a)). In this embodiment, by providing the first reinforcing member 126 and the second reinforcing member 128 in the range D1, it is possible to efficiently absorb the load from the power unit. Therefore, it is possible to efficiently suppress deformation and vibration of the side member 102 in the vertical and vehicle width directions.

[0052] In this embodiment, the first reinforcing member 126 is provided such that the main wall portion 130 is located on the extension line L1 of the rear wall portion 136 on the rear side of the first bracket 114. Also, the second reinforcing member 128 is provided such that the main wall portion 134 is located on the extension line L2 of the front wall portion 138 on the front side of the second bracket 116. That is, the main wall portion 130 and the main wall portion 134 are arranged in the same plane as the rear wall portion 136 and the front wall portion 138, respectively.

[0053] According to the above configuration, by providing the first reinforcing member 126 and the second reinforcing member 128 on the extensions of the wall portions of the first bracket 114 and the second bracket 116, respectively, the first reinforcing member 126 and the second reinforcing member 128 can efficiently absorb the load from the power unit input to the side member 102 via the first bracket 114 and the second bracket 116.

[0054] Fig. 5 is an enlarged view of the patch member 118 in Fig. 2. Fig. 5(a) is an enlarged perspective view of the patch member 118 in Fig. 2.

[0055] The patch member 118 has a bulging portion 140 at the center, and the periphery of the bulging portion 140 is a flange region 142 that contacts the fender apron panel 104. The upper fixing portion 124 is implemented as a fastening portion of a bolt provided at the center of the bulging portion 140.

[0056] A plurality of spot welds P1 to P6 are provided in the flange region 142 around the upper fixing portion 124 of the patch member 118. As a result, the patch member 118 can receive and absorb the load from the mount member 112 (see FIG. 1(a)) applied to the upper fixing portion 124 as a whole, and suppress the deformation of the fender apron panel 104.

[0057] FIG. 5(b) is a cross-sectional view taken along the line C-C in the vicinity of the patch member 118 of FIG. 2.

[0058] Among the fender apron panel 104, the apron side wall portion 148 is a portion that extends upward from the side member 102 (see FIG. 4(a) etc.) and forms the side wall of the power unit mounting room. An apron flange 144 is provided as a flange-like portion on the upper end side of the apron side wall portion 148.

[0059] The apron flange 144 is formed so as to bend and extend outward in the vehicle width direction from the upper end of the apron side wall portion 148. The apron flange 144 is formed so as to be continuous with the upper surface portion 146 (see FIG. 6(a)) of the cowl side member 110 and enables attachment of vehicle body panels and the like.

[0060] The patch member 118 is installed so as to straddle from the apron side wall portion 148 to the apron flange 144 of the fender apron panel 104. With this configuration, the mount member 112 (see FIG. 1(a)) can disperse the load from the power unit more by utilizing the patch member 118 and the fender apron panel 104.

[0061] Referring to FIG. 2 again. The upper fixing portion 124 is provided within a range D1 between the front fixing portion 120 and the rear fixing portion 122 in the vehicle longitudinal direction.

[0062] Within the range D1 between the front fixing portion 120 and the rear fixing portion 122 described above, the first reinforcing member 126 and the second reinforcing member 128 are present and the rigidity is improved. Therefore, by providing the upper fixing portion 124 within the range D1 as well, it becomes possible to more efficiently absorb the load from the power unit.

[0063] In particular, in this embodiment, as the fixing portions of the mounting member 112 (see FIG. 1(a)), a total of three fixing portions, namely the upper fixing portion 124, the front fixing portion 120, and the rear fixing portion 122, are arranged so as to form a triangle T1 when viewed from the vehicle width direction. With this configuration, it becomes possible to efficiently absorb the load propagated from the power unit via the mounting member 112 and suppress vibration. Further, according to this structure, it is possible to widely cope with loads not only in the vertical, horizontal, but also in the rotational directions generated in the power unit mounting room, and suppress vibration.

[0064] FIG. 6 is a view showing the vicinity of the fender apron panel 104 in FIG. 1(b). FIG. 6(a) is a view of the state where the patch member 118 is removed from the fender apron panel 104 in FIG. 1(b).

[0065] The apron flange 144 of the fender apron panel 104 is formed to extend obliquely downward from the cowl side member 110 toward the front side of the vehicle. And, an apron bulging region 150 is formed at the upper part of the apron side wall portion 148 of the fender apron panel 104 as a three-dimensional shaped region along the apron flange 144.

[0066] The apron bulging region 150 is a portion provided by bulging the upper region along the apron flange 122 of the apron side wall portion 148 inward in the vehicle width direction. The above-described patch member 118 is attached so as to straddle the apron bulging region 150 and the apron flange 144.

[0067] FIG. 6(b) is a view of the vicinity of the apron bulging region 150 in FIG. 6(a) as viewed from the outside in the vehicle width direction. The apron bulging region 150 is provided so as to protrude inward in the vehicle width direction. The apron bulging region 150 is provided with an upper fixing portion 152 as a portion where the upper fixing portion 124 of the patch member 118 (see FIG. 5(b)) is overlapped. The upper fixing portion 152 can be implemented as a fastening hole, and for example, it is possible to use a bolt 154.

[0068] In the fender apron panel 104, the region extending from the apron flange 144 to the apron bulging region 150 has a three-dimensionally changing shape, a large cross-sectional second moment of inertia, and is difficult to bend. Therefore, by installing the patch member 118 (see FIG. 5(b)) so as to straddle the apron flange 144 and the apron bulging region 150, the load transmitted from the power unit via the mount member 112 (see FIG. 1(a)) can be dispersed to a portion of the fender apron panel 104 that is highly rigid and difficult to bend. And thereby, it becomes possible to suppress the sway in the vehicle width direction.

[0069] As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings. Needless to say, the present invention is not limited to such examples. It is obvious that those skilled in the art can conceive of various modification examples or correction examples within the scope described in the claims, and it is naturally understood that those also belong to the technical scope of the present invention.
