Description

[Technical Field]

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

[0002] Conventionally, to prevent the driver from overlooking pedestrians or low-profile structures on the side of the vehicle and causing interference with the vehicle, triangular windows that ensure the driver's side visibility have been provided on the front side of the door section and the front lower part of the front pillar upper section of the vehicle. Furthermore, in order to improve the aerodynamic characteristics around the door mirrors while driving, the vehicle body structure is designed to minimize the number of uneven parts around the triangular windows, for example.

[0003] In the vehicle body structure described above, an upper flange portion extending in the vertical direction is formed on the inner side of the front fender upper in the vehicle width direction, and the upper flange portion is fastened and fixed to the front pillar portion with a fastening bolt extending laterally from the inner side to the outer side in the vehicle width direction. Furthermore, a technology has been disclosed in which a front pillar and a sub-window opening are provided on the side of the front part of the vehicle body, and the area between the rear part of the hood and the lower part of the front pillar is continuously formed in a downwardly convex arc shape in a side view, thereby widening the visibility range of the front window glass in the vehicle width direction and improving the field of view in front of the vehicle body (see, for example, Patent Document 1).

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-308014 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the technology described in Patent Document 1, the bottom edge of the sub-window opening on the underside of the vehicle is set at the same height as the bottom edge of the door window glass of the vehicle. Therefore, while consideration is given to expanding the visibility range in front of the vehicle, there is a risk that consideration is not given to expanding the visibility range for the driver to see short pedestrians or structures on the underside and sides of the vehicle.

[0006] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide a vehicle body structure that improves aerodynamic characteristics during driving and expands the driver's visibility range. [Means for solving the problem]

[0007] One or more embodiments of the present invention propose a vehicle body structure that includes a side visibility window section that opens on the outer side of the vehicle in the vehicle width direction, lower than the bottom edge of the door window glass section in the front door section, and that expands the visibility range of the lower outer side in the vehicle width direction from the driver's seat where the driver of the vehicle is seated, and a fender fin section on the outer side of the side visibility window in the vehicle width direction, where the fender fin section has a plate thickness direction in the fore-and-aft direction of the vehicle and edges that extend in the vertical direction and in the vehicle width direction, and has ventilation openings that penetrate in the fore-and-aft direction of the vehicle, and is arranged adjacent to each other with gaps between them. [Effects of the Invention]

[0008] According to one or more embodiments of the present invention, it is possible to improve aerodynamic characteristics during driving and to extend the driver's visibility range. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] A vehicle body structure 10 according to this embodiment will be described with reference to FIGS. 1 to 8. FIG. In this embodiment, the vehicle V is described as having a driver's seat S1 on the left side when facing the vehicle's traveling direction, and a body structure 10 on the outer right side in the vehicle width direction when facing the vehicle's traveling direction. The vehicle body structure 10 may be provided on the outer left side in the vehicle width direction when facing the vehicle traveling direction.

[0011] <Embodiment> A vehicle body structure 10 according to this embodiment will be described with reference to FIGS. 1 to 5. FIG.

[0012] <About Body Structure 10> As shown in Fig. 1, a vehicle V is provided with a driver's seat S1 and a passenger seat S2 as a driver's seat where a driver P sits, on the vehicle rear side of a front panel portion FP, and a vehicle body structure 10 is provided on the outer right side in the vehicle width direction when facing the vehicle traveling direction. Specifically, for example, as shown in Fig. 2, the vehicle body structure 10 is provided from the vehicle rear side of a front fender portion FF on the outer right side in the vehicle width direction when facing the vehicle traveling direction to the vehicle front side of a front door portion FD. A door pillar DP is provided between the front fender section FF and the front door section FD. The vehicle body structure 10 includes a side visibility window portion 100 and a fender fin portion 200.

[0013] <Regarding the side visibility window portion 100> The front fender portion FF and the front door portion FD are provided with side visibility windows 100 (side visibility windows 100a and 100b). The side visibility window 100 is opened on the outer side in the vehicle width direction of the vehicle V, below the bottom edge BL of the door window glass DW in the front door FD. The side visibility window 100 is provided at a position that expands the visibility range of the driver's seat S1 to the lower outer side in the vehicle width direction. When a side mirror SM is provided in the front door FD, the side visibility window 100 is provided below the side mirror SM. The side visibility window portion 100 is provided in the front fender portion FF and the front door portion FD by fitting a window glass portion 120 to an opening window portion 110. The window glass portion 120 is formed to fit the shape of the opening window portion 110 using a transparent glass material, resin, or the like.

[0014] Specifically, for example, as shown in FIG. 3(a), an opening window portion 110a is opened on the vehicle rear side of the front fender portion FF and a window glass portion 120a is fitted thereto so as to expand the visibility range of the underside of the vehicle of the triangular window portion TW provided on the underside of the vehicle of the upper front pillar portion UP and the front side of the door pillar DP. Furthermore, for example, as shown in FIG. 3(b), an opening window portion 110b is opened on the front side of the vehicle of the front door portion FD and a window glass portion 120b is fitted thereto so as to expand the visibility range below the vehicle beyond the bottom edge BL of the door window glass portion DW provided in the front door portion FD. In this case, when the door window glass portion DW is provided slidably, the opening window portion 110b and the window glass portion 120b may be provided on both the inner side and the outer side in the vehicle width direction of the front door portion FD. A rectangular window glass portion 120 (window glass portion 120a, window glass portion 120b) is fixed to the opening window portion 110 (opening window portion 110a, opening window portion 110b) using a material such as transparent glass or transparent resin, and is fitted to the inside of the opening window portion 110.

[0015] <About the fender fin part 200> As shown in FIG. 2, the fender fin portion 200 is provided on the outer side of the side visibility window portion 100 in the vehicle width direction. The fender fin portion 200 is fixed to the side visibility window portion 100, the front fender portion FF, or the front door portion FD. Fender fin portion 200 has a thickness direction in the vehicle longitudinal direction, sides extending in the vehicle vertical direction and in the vehicle width direction, and is formed with a plurality of fins 210 each having ventilation openings that penetrate in the vehicle longitudinal direction. Fins 210 are provided adjacent to each other with gaps SP between them from the front to the rear of the vehicle in fender fin portion 200. A driver P seated in the driver's seat S1 can see the outside of the lower part in the vehicle width direction through the gap SP provided between the side viewing window portion 100 and the adjacent fin 210.

[0016] Each fin 210 is formed of a material such as resin into a flat plate shape with its thickness direction extending in the longitudinal direction of the vehicle. As shown in Figures 4(a) to 4(c), each fin 210 has a side SH (side SHa to side SHc) extending in the vertical direction of the vehicle and a side SW (side SWa to side SWc) extending in the vehicle width direction.

[0017] A ventilation opening OP penetrating in the longitudinal direction of the vehicle is provided in each fin 210. The size and position of the ventilation opening OP provided in each fin 210 differ depending on the fin 210. The size of the ventilation opening OP formed by each fin 210 is formed to gradually decrease from the front side of the vehicle toward the lower side of the vehicle of the door mirror portion DM. The positions of the ventilation openings OP provided in each fin 210 are arranged to be successively lower toward the bottom of the vehicle from the front to the rear of the vehicle so as to guide the traveling wind to the underside of the door mirror section DM. Specifically, for example, the fins 210a, 210b, and 210c are provided with ventilation openings OP (ventilation openings OPa, OPb, and OPc) that are different in size and position. The fin 210a provided on the vehicle front side of the front fender portion FF is provided with a ventilation opening OPa that is larger than the ventilation openings OPb and OPc provided in the fins 210b and 210c. As the fin mounting position moves toward the rear of the vehicle, the ventilation openings OPb and OPc provided in the fins 210b and 210c become successively smaller and are located further downwards on the vehicle.

[0018] Furthermore, sides SH and SW of each fin 210 in fender fin portion 200 are formed to smoothly continue into envelope surface ES that extends from front fender portion FF to rear fender portion RF. In other words, the outer shape of each fin 210 is formed to have a different shape to match envelope surface ES, which is formed based on the aerodynamic characteristics and design of vehicle V when it is traveling.

[0019] The sides SW of each fin 210 extending from the inner side in the vehicle width direction to the outer side in the vehicle width direction are provided so as to face in the radial direction with a predetermined position CP in the driver's seat S1 as the center. The predetermined position CP here is a position that assumes the eye position of the driver P seated in the driver's seat S1, and can be, for example, approximately the center in the vehicle width direction on the front side of the headrest when the back seat of the driver's seat S1 is in an upright position, as shown in Figures 1 and 2. Specifically, for example, the fin 210a provided on the front side of the front fender portion FF is disposed so that the center line of the side SWa of the fin 210a when viewed from above the vehicle is oriented in a direction that coincides with the radial direction centered on a predetermined position CP, as shown in Fig. 5(a). In other words, the center line of the fin 210a when viewed from above the vehicle is disposed at an inclination angle α with respect to the vehicle width direction. For example, the fin 210b provided on the vehicle rear side of the front fender portion FF is disposed so that the center line of the side SWb of the fin 210b when viewed from above the vehicle is oriented in a direction that coincides with the radial direction centered on a predetermined position CP, as shown in Fig. 5(b). In other words, the center line of the fin 210b when viewed from above the vehicle is disposed at an inclination angle β with respect to the vehicle width direction. For example, the fin 210c provided on the vehicle rear side of the front door portion FD is disposed so that the center line of the side SWc of the fin 210c when viewed from above the vehicle is oriented in a direction that coincides with the radial direction centered on a predetermined position CP, as shown in Fig. 5(c). In other words, the center line of the fin 210c when viewed from above the vehicle is disposed at an inclination angle γ with respect to the vehicle width direction. At this time, the tilt angle α is the largest angle, and the tilt angle γ is the smallest angle.

[0020] <Actions and Effects> The operation of the vehicle body structure 10 according to this embodiment configured as described above will be described with reference to FIGS.

[0021] (Regarding side visibility range) The vehicle V has a vehicle body structure 10 in which a side visibility window portion 100 is opened below the bottom edge BL of the door window glass portion WG of the front door portion FD on the vehicle rear side of the front fender portion FF and on the vehicle front side of the front door portion FD of the vehicle V. The side visibility window portion 100 has a window glass portion 120 fitted to an opening window portion 110. Since the side viewing window section 100 is opened below the bottom edge BL of the vehicle, the driver P's viewing range is expanded downward and outward in the vehicle width direction so that he or she can see pedestrians or obstacles OB that are shorter than the bottom edge BL of the door window glass section DW or the door mirror section DM.

[0022] A fender fin portion 200 is provided on the outer side in the vehicle width direction of the side visibility window portion 100. A plurality of fins 210 are arranged on the fender fin portion 200. As shown in FIGS. 5(a) to 5(c), the fins 210 are provided adjacent to each other with a gap SP therebetween from the front side to the rear side of the vehicle. In this case, the sides SW of each fin 210 extending from the inner side in the vehicle width direction to the outer side in the vehicle width direction are oriented in a radial direction centered on a predetermined position CP on the driver's seat S1. In other words, the multiple fins 210 in the fender fin portion 200 are provided at an inclination angle that does not limit the field of vision of the driver P. Therefore, the visibility range of the driver P is expanded from the front side of the fender fin portion 200 to the rear side of the vehicle toward the lower outside in the vehicle width direction without being limited by the shape of the fin 210.

[0023] As shown in Figure 6, a driver P seated in the driver's seat S1 can view the lower outside in the vehicle width direction from a predetermined position CP on the driver's seat S1 through a gap SP provided between the side viewing window section 100 and the adjacent fin 210. At this time, for example, at the location where the fin 210c is provided, the driver P visually recognizes the lower outer side in the width direction above the vehicle from the bottom side BL of the door window glass portion DW, as shown by the arrow AR1. Furthermore, below the bottom edge BL of the door window glass portion DW, as shown by arrow AR2, the driver P can see the lower outer side in the vehicle width direction below the bottom edge BL of the door window glass portion DW through the gap SP provided in the side viewing window portion 100 and the fin 210c, and can also see the lower outer side in the vehicle width direction through the ventilation opening OPc provided in the fin 210c. In other words, the driver P's visibility range is expanded by the side visibility window portion 100 and the fender fin portion 200 from the bottom edge BL of the door window glass portion DW toward the lower and outer sides in the vehicle width direction so that the driver P can see the upper side of the vehicle and pedestrians or obstacles OB that are shorter than the bottom edge BL of the door window glass portion DW or the door mirror portion DM.

[0024] Furthermore, the sides SH and SW of each fin 210 are formed to smoothly continue into the envelope surface ES that extends from the front fender section FF through the front door section FD to the rear fender section RF, and there is a gap SP between adjacent fins 210. The fins 210 in the fender fin portion 200 are formed smoothly and continuously on the envelope surface ES without blocking the gap SP, allowing the driver P to stably view the lower outer side in the vehicle width direction toward the lower outer side in the vehicle width direction.

[0025] As described above, by providing the side visibility window portion 100 below the bottom edge BL of the door window glass portion DW of the vehicle V or further forward and further below the vehicle than the door mirror portion DM, the vehicle body structure 10 expands the side visibility range for viewing pedestrians or obstacles OB that are shorter than the bottom edge BL of the door window glass portion DW or the door mirror portion DM. A fender fin portion 200 provided on the outer side of the side visibility window portion 100 in the vehicle width direction has a plurality of fins 210 provided adjacent to each other with a gap SP therebetween. Furthermore, each fin 210 is provided with an inclination angle that does not restrict the field of vision of the driver P. Therefore, by looking through the gaps SP provided between the multiple fins 210 in the fender fin portion 200, the driver P's viewing range is expanded downward and outward in the vehicle width direction so that he or she can see pedestrians or obstacles OB that are shorter than the bottom edge BL of the door window glass portion DW or the door mirror portion DM.

[0026] (Aerodynamic characteristics during driving) When the vehicle V is traveling, a traveling wind is generated from the front side of the vehicle to the rear side of the vehicle. A plurality of fins 210 are provided adjacent to each other on the fender fin portion 200. As shown in Fig. 7, the wind generated by running flows along the adjacent fins 210 from the outer side in the vehicle width direction toward the inner side in the vehicle width direction. The fins 210 are provided with ventilation openings OP that guide the flow of wind generated when the vehicle V is traveling. The wind that flows in along the fins 210 flows toward the rear of the vehicle through the ventilation openings OP provided in the fins 210, as shown by arrow BR1.

[0027] The size of the ventilation opening OP formed by each fin 210 is formed to gradually decrease from the front side of the vehicle toward the lower side of the vehicle of the door mirror portion DM. The positions of the ventilation openings OP provided in each fin 210 are arranged to be successively lower toward the bottom of the vehicle from the front to the rear of the vehicle so as to guide the traveling wind to the underside of the door mirror section DM. The ventilation openings OPb and OPc formed in the fins 210b and 210c become smaller toward the rear of the vehicle and are located lower on the vehicle. The wind that enters the gap SP is guided to the ventilation openings OP and passes under the side mirror SM as shown by arrows BR2 and BR3.

[0028] Each fin 210 faces in a radial direction centered on a predetermined position CP, so that the traveling wind heading toward each fin 210 is guided to the corresponding gap SP. The traveling wind that enters the gap SP is guided to the ventilation opening OP and passes below the side mirror SM, as indicated by arrows BR2 and BR3.

[0029] Furthermore, as shown in FIG. 8(a), the sides SH and SW of each fin 210 are formed to smoothly continue into an envelope surface ES that extends from the front fender portion FF, through the front door portion FD, and to the rear fender portion RF. As indicated by arrows CR1 to CR3, the wind traveling from the front of the vehicle to the rear of the vehicle on the outer side in the vehicle width direction is guided to flow along the envelope surface ES, which is smoothly continuous from the front fender section FF to the rear fender section RF. As shown in Figures 8(a) and 8(b), the vehicle-outside shape of the fender fin portion 200 is formed smoothly and continuously with the envelope surface ES, and the generation of air resistance and driving noise due to the wind while the vehicle is running is limited, thereby improving the aerodynamic characteristics of the vehicle V while it is running. Furthermore, the vehicle exterior shape of the fender fin portion 200 is formed smoothly and continuously with the envelope surface ES, thereby reducing the impact on the design of the vehicle V, such as the side silhouette.

[0030] As described above, ventilation openings OP are provided in fins 210 of fender fin portion 200, and the vehicle-outside shape of fender fin portion 200 is formed smoothly and continuously with envelope surface ES, thereby limiting the generation of air resistance due to wind while traveling and the generation of traveling noise, thereby improving the aerodynamic characteristics of vehicle V while traveling.

[0031] As explained above, the vehicle body structure 10 according to this embodiment is provided with a side visibility window 100 that opens on the outer side of the vehicle V in the vehicle width direction, below the bottom edge BL of the door window glass DW in the front door FD, and that extends the visibility range of the lower outer side in the vehicle width direction from the driver's seat S1 where the driver P of the vehicle V is seated, and a fender fin section 200 on the outer side of the side visibility window 100 in the vehicle width direction, the fender fin section 200 having a plurality of fins 210 arranged adjacent to each other with gaps SP between them, the fins 210 having a side SH that extends in the vehicle vertical direction and a side SW that extends in the vehicle width direction, with the vehicle fore-and-aft direction being the thickness direction of the plate and extending in the vehicle vertical direction and in the vehicle width direction, and having ventilation openings OP that penetrate in the vehicle fore-and-aft direction. In other words, the window glass portion 120 is fitted to the opening window portion 110 to form a side visibility window portion 100 below the bottom edge BL of the door window glass portion DW of the vehicle V, and there is a gap SP between adjacent fins 210 in the fender fin portion 200, thereby expanding the visibility range toward the lower outside in the vehicle width direction. Therefore, by providing the side visibility window portion 100 below the bottom edge BL of the door window glass portion DW, the visibility range can be expanded downward and outward in the vehicle width direction. Furthermore, the plurality of fins 210 provided on the outer side of the side visibility window portion 100 in the vehicle width direction are provided with ventilation openings OP that guide the flow of wind generated when the vehicle V is traveling. Therefore, the fins 210 provided on the outside of the side visibility window section 100 are provided with ventilation openings OP that guide the flow of wind generated when the vehicle V is moving, and by limiting the generation of air resistance and running noise caused by the wind, the body structure 10 can improve the aerodynamic characteristics of the vehicle V when it is moving. This improves the aerodynamic characteristics during driving and also expands the driver's field of view.

[0032] In the vehicle body structure 10 according to this embodiment, the size and position of the ventilation openings OP provided in the fins 210 differ depending on the fins 210. That is, the size of the ventilation openings OP formed in each fin 210 is gradually reduced from the front of the vehicle toward the vehicle underside of the door mirror DM. The positions of the ventilation openings OP formed in each fin 210 are gradually lowered from the front of the vehicle toward the rear of the vehicle so as to guide the traveling wind to the vehicle underside of the door mirror DM. The traveling wind that enters the gaps SP between adjacent fins is guided by the ventilation openings OP to pass through the vehicle underside of the side mirror SM. Therefore, by directing the traveling wind flowing toward the door mirror section DM, where traveling noise is likely to be generated, to the underside of the vehicle of the door mirror section DM, and limiting the generation of air resistance and traveling noise due to the traveling wind, the body structure 10 can improve the aerodynamic characteristics of the vehicle V while it is traveling. Furthermore, the fins 210 are provided with ventilation openings OP that penetrate the fins 210, so that the driver P can see the lower outer side in the vehicle width direction through the ventilation openings OP. This improves the aerodynamic characteristics during driving and also expands the driver's field of view.

[0033] In the body structure 10 of this embodiment, the side SW extending in the vehicle width direction, which is the side extending from the inside of the vehicle width direction of the fin 210 to the outside of the vehicle width direction, is arranged facing radially from a predetermined position CP in the driver's seat S1, which is the driver's seat where the driver P is seated. In other words, since the side SW of the fin 210 faces radially with a predetermined position CP at the driver's seat S1 as the center, a visible range is secured from the predetermined position CP, which is assumed to be the eye position of the driver P, penetrating the gap SP between adjacent fins 210 toward the lower outside in the vehicle width direction. Therefore, a stable viewing range is secured from the gaps SP between adjacent fins 210 toward the lower outside in the vehicle width direction, and the vehicle body structure 10 can ensure a stable viewing range toward the lower outside in the vehicle width direction. Furthermore, each fin 210 faces in a radial direction centered on a predetermined position CP, so that the traveling wind heading toward the fin 210 is guided into each gap SP. The traveling wind that enters the gap SP is guided to pass through the ventilation opening OP and below the side mirror SM. Therefore, by directing the traveling wind flowing toward the door mirror section DM, where traveling noise is likely to be generated, to the underside of the vehicle of the door mirror section DM, and limiting the generation of air resistance and traveling noise due to the traveling wind, the body structure 10 can improve the aerodynamic characteristics of the vehicle V while it is traveling. This improves the aerodynamic characteristics during driving and also expands the driver's field of view.

[0034] In the body structure 10 of this embodiment, the side SH extending in the vertical direction of the vehicle and the side SW extending in the width direction of the vehicle as the outer side of each fin 210 are arranged on an envelope surface ES that is continuous with the external shape formed on the side of the vehicle V. In other words, the sides SH and SW of each fin 210 are formed to smoothly continue into the envelope surface ES that extends from the front fender portion FF to the rear fender portion RF. Therefore, the vehicle body structure 10 can improve the aerodynamic characteristics of the vehicle V while it is in motion by guiding the wind traveling from the front of the vehicle to the rear of the vehicle on the outside in the vehicle width direction along the envelope surface ES that is smoothly and continuously provided from the front fender section FF to the rear fender section RF, thereby limiting the generation of air resistance and traveling noise caused by the wind traveling. Furthermore, there is a gap SP between adjacent fins 210 in the fender fin portion 200, and the fins 210 are formed smoothly and continuously on the enveloping surface ES without obstructing the gap SP, so that the body structure 10 can ensure a stable visibility range toward the lower outside in the vehicle width direction. This improves the aerodynamic characteristics during driving and also expands the driver's field of view.

[0035] Although the vehicle body structure 10 in the embodiment according to this embodiment has been described as being provided in the front fender portion FF and the front door portion FD, it may also be provided in the rear door portion and the rear fender portion.

[0036] Although the fin 210 in the vehicle body structure 10 according to the embodiment has been described as being formed in a flat plate shape, it may be formed so as to be bent in a dogleg shape having a bending point at any position in the vertical direction of the vehicle when viewed from the side of the vehicle. In this case, it is desirable that the bent tip be provided on the front side of the vehicle in consideration of aerodynamic characteristics.

[0037] The above describes in detail an embodiment of the present invention with reference to the drawings, but the specific configuration is not limited to this embodiment, and includes designs within the scope of the gist of the present invention. [Explanation of symbols]
