Description

  The present invention relates to a vehicle body structure constituting at least a part of a vehicle body.

  An automobile body (body) is configured to have a plurality of surface portions. For example, a front window is disposed at the front, a rear window is disposed at the rear, a roof is disposed at the upper portion, and doors are disposed at left and right side portions. In general, pillars that support the roof are arranged on both the left and right sides of the front window and the rear window.

  Japanese Patent Application Laid-Open No. 2004-133830 discloses a vehicle field assist device for projecting, in real time, an external image of a pillar photographed by a camera onto a retroreflecting surface formed on the inner surface of the pillar at a position that hinders the driver's field of view. Is disclosed, and it is proposed to eliminate blind spots caused by pillars.

Japanese Patent Laid-Open No. 2005-199934

  From the viewpoint of safe driving, it is desirable to eliminate as much as possible the portion that becomes a blind spot of the driver during driving so that the driver can easily see the surroundings of the vehicle.

  Patent Document 1 proposes to project an image captured by a camera onto the inner surface of the pillar, but the cost increases, such as forming a retroreflective surface on the inner surface of the pillar or requiring a camera or projector. There are problems such as an increase in weight and a decrease in productivity.

  In addition, for example, a conventional metal pillar may be formed of a transparent resin, such as forming a transparent metal around the window. However, simply using a transparent material instead of a metal material provides sufficient strength. It is difficult to secure. Therefore, there is a possibility that steering stability is lowered, and that a vehicle interior noise such as a booming noise is likely to occur during traveling.

  An object of the present invention is to provide a vehicle body structure that can eliminate blind spots while ensuring strength.

The vehicle body structure according to one aspect of the present invention is:
A plurality of face portions;
A ridge line part that connects the surface parts adjacent to each other;
A reinforcement member fixed between the adjacent surface portions across the ridge line portion,
The surface portion, the ridge line portion, and the reinforcing member are formed of a transparent material, and the surface portion and the ridge line portion are integrally formed.

  According to the above-described vehicle body structure, the strength is easily secured to some extent by integrally forming the plurality of surface portions and the ridge line portions that connect the adjacent surface portions. Furthermore, sufficient strength can be obtained by fixing the reinforcing member between adjacent surface portions across the ridge line portion. Moreover, since the said vehicle body structure is entirely formed with the transparent material, it can ensure a visual field widely and can eliminate a blind spot by providing in the location which ensures a driver | operator's visual field. Therefore, the vehicle body structure can eliminate blind spots while ensuring strength. In addition, since the vehicle body structure constitutes an assembly in which a plurality of surface portions are integrated, it is easy to assemble to the vehicle, and it is not necessary to join the surface portions with an adhesive or the like. The car body can be manufactured at low cost with high productivity.

With reference to FIGS. 1-3, the vehicle body structure 10 which concerns on Embodiment 1 is demonstrated. As shown in FIG. 1, the vehicle body structural body 10 according to the first embodiment is an example applied to the front portion of the vehicle body 1, and is a part that constitutes the front window of the vehicle body 1. The vehicle body 1 is of a wagon type, and a door 3 is disposed on the left and right side portions, a roof 4 is disposed on the upper portion, and a back door (not shown) is disposed on the rear portion. One of the characteristics of the vehicle body structure 10 is that a plurality of surface portions 11, a ridge line portion 12 that connects the adjacent surface portions 11 to each other, and a reinforcing member 13 that is fixed between the adjacent surface portions 11 across the ridge line portion 12. It is in the point provided with. Another feature of the vehicle body structure 10 is that the surface portion 11, the ridge line portion 12, and the reinforcing member 13 are formed of a transparent material, and the surface portion 11 and the ridge line portion 12 are integrally formed. Hereinafter, the vehicle body structure 10 of Embodiment 1 will be described in detail.

(Face part)
As shown in FIG. 1, the vehicle body structure 10 has four surface portions 11, a first surface portion that forms a front window 111, and two second surface portions that form a front side window 112 (both left and right sides). And a third surface portion that forms the front roof window 113. The front side window 112 is provided from the front window 111 to the front of the left and right doors 3 (only the left front side window 112 is shown in FIG. 1). The front roof window 113 is provided from the front window 111 to the front portion of the roof 4 and is joined to the front end of the roof panel 40. The roof 4 of the vehicle body 1 shown in FIG. 1 includes a front roof window 113 and a roof panel 40. The front window 111 (first surface portion), the front side window 112 (second surface portion), and the front roof window 113 (third surface portion) are each formed of a transparent material.

(Ridge part)
Between the surface parts 11 adjacent to each other, there is a ridge line part 12 that connects the surface parts 11 to each other. In the case of the vehicle body structure 10, a first ridge 121 that connects the front window 111 and the front side window 112, a second ridge 122 that connects the front window 111 and the front roof window 113, and the front side window 112 And a third ridgeline portion 123 connecting the front roof window 113. The surface portions 11 (111 to 113) and the ridge line portions 12 (121 to 123) are integrally formed of a transparent material, and the adjacent surface portions 11 are continuous across the ridge line portion 12.

(Reinforcing member)
Further, in the vehicle body structure 10, the reinforcing member 13 is fixed between the adjacent surface portions 11 across the ridge line portion 12. The reinforcing member 13 is formed of a transparent material in a fire beam shape, and is disposed along the ridgeline portion 12. The reinforcing member 13 contributes to the strength and rigidity of the vehicle body structure 10.

  In the vehicle body structure 10, as shown in FIG. 1, as the reinforcing member 13, the first reinforcing member 131 disposed on the first ridge line portion 121 (between the surface portions 111 and 112) and the second ridge line portion 122 (surface portion 111, 113) and a third reinforcing member 133 disposed between the third ridgeline portion 123 (between the surface portions 112 and 113). These reinforcing members 13 (131 to 133) are respectively arranged on the inner side (vehicle compartment side) of each ridgeline portion 12 (121 to 123) and fixed with a transparent adhesive or the like (see also FIGS. 2 and 3). . As the transparent adhesive, for example, an epoxy or acrylic transparent adhesive can be used. In the case of the vehicle body structure 10, the first reinforcing member 131 extends along the left and right side edges of the front window 111 and functions as a first front pillar inner panel provided on the front side of the front side window 112. The second reinforcing member 132 extends along the upper edge of the front window 111 and functions as a front header inner panel provided on the front side of the roof 4. The third reinforcing member 133 extends along the upper edge of the front side window 112 and functions as a roof side inner panel provided on both side edges of the roof 4.

  Further, in the vehicle body structure 10 shown in FIG. 1, the edge reinforcing member 134 is fixed along the inner surface of the rear edge of the front side window 112. The edge reinforcing member 134 is formed of a transparent material in a plate shape, and functions as a second front pillar inner panel provided on the rear side (door 3 side) of the front side window 112. That is, each reinforcing member 13 (131 to 134) plays a role of various conventional inner panels.

  As a transparent material which forms the surface part 11, the ridgeline part 12, and the reinforcement member 13, transparent resin and glass are mentioned, for example. As the transparent resin, for example, a polycarbonate resin or an acrylic resin can be suitably used. Transparent resin is lighter than glass and has excellent moldability, which is advantageous in terms of weight reduction and productivity. When using a transparent resin, for example, it may be formed by injection molding. The surface portion 11 and the ridge line portion 12 are integrally formed of a transparent material, and all of them may be formed of a transparent resin, or all of them may be formed of glass. When the surface portion 11 and the ridge line portion 12 are formed of the same transparent resin, they may be integrally formed by injection molding or the like. Further, the surface portion 11 and the ridge line portion 12 can be formed of different kinds of transparent materials. For example, when the surface portion 11 is formed of glass and the ridge line portion 12 is formed of a transparent resin, the glass surface portion 11 and the transparent resin ridge line portion are formed by insert-molding the ridge line portion 12 with a transparent resin with respect to the glass forming the surface portion 11. And 12 are integrally formed. Alternatively, at least one of the surface portions 11 can be formed of glass, and the rest can be formed of a transparent resin. In this case, it is possible to integrally mold the glass forming at least one surface portion 11 (for example, the front window 111) by insert molding the remaining surface portion 11 and the ridge line portion 12 with a transparent resin.

  The vehicle body structure 10 is assembled to the main body of the vehicle body 1 excluding the vehicle body structure 10. Assembling of the vehicle body structure 10 may be performed by joining the thin plate-like metal (for example, steel) inner panel on the main body side by fastening with, for example, a bolt or a rivet, or bonding with an adhesive. The vehicle body constituting body 10 may be joined to the main body via an appropriate seal member.

Furthermore, the reinforcement member 13 (131-133) is fixed between the adjacent surface parts 11 straddling the ridgeline part 12 (121-123), and the intensity | strength which can be practically used can be ensured. In the case of the vehicle body structure 10, it is formed in a box shape with the four surface portions 11 constituting the front window 111, the front side window 112, and the front roof window 113, so that the strength and rigidity of the vehicle body structure 10 can be relatively ensured. easy. In addition, since the reinforcing members 13 (131 to 133) are disposed on the inner side (vehicle interior side) of the ridge line portions 12 (121 to 123), they can be prevented from being damaged by a wiper blade or the like. Visibility defects due to sticking can be suppressed.

  In the vehicle body constituting body 10, one of the surface portions 11 is a front window 111, and is assembled to the front portion of the vehicle body 1 to constitute the front window. Since the entire vehicle body structure 10 is formed of a transparent material, a wide field of view in front of the vehicle can be secured, and blind spots caused by conventional front pillars and front headers can be eliminated. Specifically, it is continuous from the front window 111 to the front side window 112, and it is possible to eliminate a portion that becomes a blind spot when traveling or turning left or right. Also, the front roof window 113 is continuous from the front window 111, and it is easy to visually recognize the traffic lights and signs above.

  Since the vehicle body structure 10 constitutes an assembly in which a plurality of surface portions 11 are integrated, it is easy to assemble, and it is not necessary to join the surface portions 11 with an adhesive or the like. Good and cheap to manufacture.

  In the above-described first embodiment, the configuration having the surface portions 11 of the front window 111, the front side window 112, and the front roof window 113 is exemplified, but the present invention is not limited to this.
