Description

  The present invention relates to a windshield portion structure in which a front pillar is bent toward the vehicle rear side.

  The front pillar of the vehicle is provided between the rear of the front portion of the vehicle and the front end of the roof portion, and holds the left and right edges of the windshield. The front pillar is formed with a predetermined strength to support the front end portion of the roof portion and to secure a living space for the occupant in the event of an emergency. Therefore, since the front pillar has a relatively thick cross section and is provided in front of the driver, a blind spot may be formed obliquely in front of the driver.

  In view of this, there has been invented a windshield in which the position of the front pillar is moved to the rear side of the vehicle to improve the visibility in front of the vehicle. For example, in International Publication No. WO2002 / 100671, a windshield is continuously formed integrally from the front of the vehicle to the side portion of the vehicle in a substantially U shape, and the front pillar is moved to the rear side of the vehicle for driving. An example in which the field of view obliquely forward from the seat is improved is described.

On the other hand, the windshield is relatively weak and is formed so as to be crushed and absorb the impact if it collides with a pedestrian, but the front pillar is a structural member of the vehicle. If the pedestrian is in contact with the front pillar, the pedestrian may be seriously damaged. From this point, it is preferable to move the front pillar to the rear side of the vehicle because a pedestrian can be prevented from coming into direct contact with the front pillar.
WO2002 / 100671

  However, from the viewpoint of safety, laminated glass is often used for the windshield at present. Laminated glass has a property that it is difficult to process at an angle close to a right angle because a resinous intermediate film is sandwiched between two sheets of glass. Therefore, it is practically impossible to inexpensively mass-produce the above-described windshield bent in a U-shape with laminated glass.

  In addition, from the viewpoint of protecting the occupant, in the event of an emergency, the occupant's living space can be reliably secured in the passenger compartment, and even if the occupant contacts the windshield, the occupant can be held so that it will not be released outside the vehicle. Toughness was required, and the desired strength could not be obtained even if two windshields on the front side and side face of the vehicle were simply connected to form a windshield.

  Thus, the windshield part including the front pillar is required to have a contradictory structure: a flexible structure that reduces damage to pedestrians in the event of an emergency and a strong structure that protects passengers in the passenger compartment. Yes.

  Further, when the windshield is formed in a U-shape, the windshields cannot be overlapped, requiring a large space for storage, and there is a problem that storage and handling of the windshield becomes inconvenient. Further, when the windshield is formed in a U-shape, there is a problem that the windshield cannot be pasted to the vehicle body using a conventional windshield pasting line.

  The present invention solves the above-mentioned problems, and can be easily formed in a windshield portion structure in which the front pillar is bent toward the rear side of the vehicle and the field of view obliquely forward is excellent, and can be easily attached to the vehicle. An object of the present invention is to provide a front windshield portion structure for a vehicle that can provide both a pedestrian protection and a passenger protection.

  In order to solve the above-mentioned problems, the present invention has a vehicle windshield part configured as follows. 1. In a vehicle windshield structure comprising a windshield mounted in front of an interior space of a vehicle and a front pillar supporting both left and right sides of the windshield, the windshield is made of laminated glass having an intermediate film and is front of the vehicle. And a side glass that is connected to the left and right sides of the front glass and arranged along the traveling direction of the vehicle, and the front pillar extends along the left and right edges of the front glass. In addition, at least in the portion where the side glass is disposed, the side glass is formed to bend along the edge of the side of the vehicle on the vehicle rear side, and further through the intermediate film for laminated glass used for the front glass, It is characterized in that a side glass is connected.

In the structure of the windshield part of the vehicle according to 2, 1, the windshield can be folded so that the side glass overlaps the front glass by an intermediate film at a connecting portion between the front glass and the side glass. And

31. The vehicle windshield structure according to 1 and 2, wherein a connecting portion of the windshield is provided with a molding portion that covers the connecting portion, and the edges of the front glass and the side glass are fixed by the molding portion. And

4 and 3, the intermediate film in the connection portion is provided with a connection hole penetrating the intermediate film in the front and back direction, and the resin material is connected to the connection hole when molding the molding part. The molding part is provided so as to sandwich the connecting part from the front and back sides, and is filled in the front and back sides of the intermediate film via

5. The vehicle windshield structure according to any one of claims 1 to 3, wherein a support member extending from the front pillar along the left and right edges of the front glass is provided, and the left and right edges of the front glass at the connecting portion are provided on the support member. And an end edge of the side glass.

6. In the windshield portion structure for a vehicle according to any one of 1 to 5, the portion of the front pillar along the front glass and the portion along the side glass are continuously formed in a substantially S shape. It is characterized by.

7. The structure of a windshield portion of a vehicle according to any one of claims 1 to 5, wherein the front pillar extends along the side glass over the entire length of the front pillar.

The vehicle windshield structure according to the present invention has the following effects.
Since the windshield is composed of a front glass and side glass, and the front pillar is bent along the edge of the side glass on the vehicle rear side, the front pillar is located on the vehicle rear side compared to a normal vehicle. Therefore, the field of view obliquely forward from the driver's seat and front passenger seat can be improved. Furthermore, since structural members such as a front pillar are not disposed on the left and right side edges of the front glass, even if it collides with a pedestrian and comes into contact, contact with the front pillar can be avoided. And even if it contact | abuts to a front glass or a side glass, a front glass or a side glass will crush and absorb an impact, Therefore The damage which a pedestrian receives can be reduced efficiently.

  In addition, the structural member (front pillar) that forms the skeleton structure of the vehicle is not formed at the mating part (connecting part) of the front glass and the side glass, but instead, the molding part is arranged to connect the front glass and the side glass. Can be fixed to the state. Therefore, the rigidity of the molding part and the like can be set appropriately and the appearance can be set freely, and high shock absorption and good visibility can be realized.

  In addition, since the front glass and the side glass are connected by a resin intermediate film for laminated glass, the vehicle should collide and the passenger collided from the passenger compartment side to the vicinity of the molding part, which is the connecting part of the windshield. Even in such a case, it is held by the resin intermediate film, and it is possible to prevent the occupant from jumping out of the vehicle by breaking through the windshield. Moreover, moderate elasticity is obtained by the resin-made intermediate film, and this can reduce damage to the occupant when it collides with the windshield.

  In addition, the front glass can be folded with a resin intermediate film so that the side glass overlaps the front glass before mounting on the vehicle body, so the front glass can be made compact when storing and transporting the front glass, making it easy to handle. it can. Accordingly, storage and transport costs can be reduced, and workability is improved. Moreover, a windshield can be affixed on a vehicle body using the conventional windshield affixing line.

  1st Embodiment of the windshield part structure of the vehicle concerning this invention is described using figures. FIG. 1 shows a vehicle 2 having the windshield structure of the present invention.

  The vehicle 2 is a passenger car type, and includes a front portion 4 and a vehicle compartment 6 as an indoor space following the front portion 4 from the front in the traveling direction (indicated by an arrow A).

The front pillar 12 is a structural member that forms the skeleton structure of the vehicle 2, and supports the front portion of the roof portion 8. Actually, the front pillar 12 extends to a floor (not shown) provided at the lower end of the vehicle 2, but here, a member between the front portion 4 and the roof portion 8 is referred to as a front pillar. .

  The front pillar 12 extends obliquely downward from the front end of the roof portion 8 toward the front in the traveling direction A of the vehicle 2 and bends downward near an intermediate position in the height direction. It is connected to the rear end portion of the portion 4 and is formed in a substantially S shape as a whole. Such a bent portion is denoted by B.

  As shown in FIG. 2, the windshield 10 includes a front glass 14 disposed in front of a vehicle compartment 6 (indoor space) of the vehicle 2 and a side glass 16 attached along the traveling direction A of the vehicle 2. The front glass 14 is between the front end of the roof portion 8 and the rear of the front portion 4, and connects the left end of the front end of the roof portion 8 and the rear left end of the front portion 4, and the front end of the roof portion 8. The windshield glass is located in a portion surrounded by a line connecting the right end portion and the right end portion behind the front portion 4.

  As shown in FIG. 4, the front glass 14 is formed of a laminated glass having a resin intermediate film 18 between two front and back glasses. This laminated glass is equivalent to the laminated glass used for a normal vehicle windshield, and the intermediate film 18 is made of, for example, PVB (polyvinyl butyral) resin.

  The side glass 16 is a windshield glass that is formed along the bent portion B of the front pillar 12, is connected to the left and right side edges of the front glass 14, and is disposed substantially along the traveling direction A of the vehicle 2. .

  As shown in FIG. 3, a molding portion 20 is provided so as to cover the connecting portion D at a portion (connecting portion D) where the left and right end edges of the front glass 14 and the end edge of the side glass 16 abut each other. . And the right and left edge of the front glass 14 and the edge of the side glass 16 are hold | maintained by the molding part 20, and the front glass 14 and the side glass 16 are being fixed so that it may become the continuous bent shape.

  The intermediate film 18 is a resin film as described above, and extends outward from the left and right edges of the front glass 14 and extends into the side glass 16. That is, the front glass 14 and the side glass 16 are both laminated glass with the intermediate film 18 interposed therebetween, and are connected to each other with a predetermined interval through the common intermediate film 18. The intermediate film 18 in the connection portion D is formed with a connection hole 28 penetrating the front and back of the intermediate film 18 at a position coincident with a hole 26 described later.

  The molding part 20 is demonstrated using FIG. 3 and FIG. The molding portion 20 includes a reinforcing member 22 provided along a butted portion (connecting portion D) between the front glass 14 and the side glass 16, and the front and back of the connecting portion D between the front glass 14 and the side glass 16 including the reinforcing member 22. The front glass 10 is composed of a resin portion 24 that is integrally molded so as to sandwich the front glass 14, and the edge of the front glass 14 on both the left and right sides and the edge of the side glass 16 are connected and fixed at a predetermined angle. The shape bent at the molding part 20 is maintained.

  The reinforcing member 22 is an elongated metal member having a substantially W-shaped cross section, and holes 26 are provided in the central portion at a predetermined interval. The material, strength, plate thickness, width, diameter of the holes 26, installation interval, and the like of the reinforcing member 22 are appropriately selected so that the molding portion 20 has a desired strength. The resin portion 24 is formed by, for example, injection molding of a resin material in a mold. The resin portion 24 is integrally provided on both sides of the intermediate film 18 by filling the front and back of the connecting portion D with the resin material passing through the hole 26 of the reinforcing member 22 and the connecting hole 28 of the intermediate film 18. Further, a rain garter 30 (see FIG. 3) is integrally formed on the front surface side of the molding portion 20 along the front glass 14 for preventing water from scattering to the side of the vehicle when the wiper is wiped.

  The front glass 14 and the side glass 16 do not have to have the same thickness and strength. If the end portion of the intermediate film 18 is securely fixed to the front pillar 12, the side glass 16 may not be laminated glass, but may be, for example, a glass laminated only on one surface side of the intermediate film 18.

  Next, the process of assembling the windshield part according to the present invention will be described.

  First, the front glass 10 is formed. The front glass 14 is formed with the intermediate film 18 interposed therebetween, and the intermediate film 18 is exposed from the left and right edges of the front glass 14, and the side glass 16 is formed on the exposed portion. . Then, the reinforcing member 22 is disposed along the connecting portion D, which is a portion where the front glass 14 and the side glass 16 are abutted, and then the resin is injected in, for example, a mold and the periphery of the reinforcing member 22 is covered with the resin portion 24. The molding part 20 is molded to connect the front glass 14 and the side glass 16 together. Thereby, the windshield 10 is formed. The resin portion 24 is provided through the front and back of the windshield 10 through the hole 26 and the connecting hole 28.

  Next, an adhesive is applied along the front end of the roof part 8, the rear end of the front part 4, and the front pillar 12, and the windshield 10 is pressed and adhered from the front side of the vehicle. In this way, the windshield 10 is attached to the front portion of the vehicle 2.

  Then, the upper end edge of the front glass 14 and the front end of the roof portion 8, the lower end edge of the front glass 14 and the rear end of the front portion 4, the left and right end edges of the upper portion of the front glass 14, and the location where the front pillar 12 is not curved, Are further bonded to each other, and the rear edge of the side glass 16 and the bent portion B bent to the lower side of the front pillar 12 are bonded to each other with an adhesive.

  Therefore, in the vehicle 2, the front pillar 12 as a structural member is bent such that the front pillar 12 is disposed on the vehicle rear side of the windshield 10, and the molding is set relatively thin at the connection portion D between the front glass 14 and the side glass 16. Since the portion 20 is arranged so as to maintain the shape of the windshield 10, it is possible to improve the oblique front view from the driver with a simple structure. Also, even if a pedestrian contacts the edge of either side of the windshield 10 in the left-right direction, the molding portion 20 is formed with low rigidity so that the impact force applied by the pedestrian is easy. In addition, the molding part 20 is crushed and damage to pedestrians can be reduced.

  Further, since the front glass 14 and the side glass 16 are connected by the intermediate film 18, an accident occurs, and an occupant enters the connecting portion D of the front glass 14 and the side glass 16 from the inside of the passenger compartment 6, that is, the molding part 20. Even if the molding portion 20 is damaged due to contact, the connection between the front glass 14 and the side glass 16 is not disconnected, and the intermediate film 18 holds the occupant. It will not be thrown out. Furthermore, since the intermediate film 18 has elasticity, it is possible to mitigate the impact and reduce occupant damage.

  Next, 2nd Embodiment of the windshield part structure of a vehicle is described using FIGS.

The arm part 37 engaged with the edge part of the left-right direction is provided. The right and left side glass 16 can be fixed in a folded state by the fixing tool 32, and the folding of the side glass 16 is easily released by removing the fixing tool 32 from the front glass 14.

  As shown in FIG. 7, a support member 40 is spanned from the vicinity of the intermediate position of the front pillar 12 to the front portion 4 above the bent portion B that is bent to the vehicle 2 lower side of the front pillar 12. The support member 40 is a metal member, has moderate rigidity and brittleness, and further has an upper surface formed so as to be continuous with the bonding surface of the front pillar 12 along the left and right edges of the front glass 14. 14 bonding surfaces C are formed.

  In the case of this embodiment, an adhesive is applied along the periphery of the front glass 14, that is, on the front end of the roof portion 8, the rear end of the front portion 4, and the bonding surface C of the left and right front pillars 12. Then, after the front glass 14 is bonded to the front portion of the vehicle 2 from the front side of the vehicle, the side glass 16 is returned from the folded state and bonded to the support member 40 and the bent portion B of the front pillar 12 with an adhesive from the left-right direction of the vehicle. . At this time, the side glass 16 is positioned by aligning the protrusion 3 (see FIG. 6) provided on the adhesive surface of the side glass 16 with a hole (not shown) provided on the adhesive surface of the bent portion B. Then, the molding part 20 is attached from the front glass 10 surface side to the connection part D which is the abutting part of the front glass 14 and the side glass 16. As shown in FIG. 8, the molding part 20 has a bolt part protruding from the back surface thereof, penetrates the hole 28 of the intermediate film 18, and is fixed to the support member 40 with a nut. In addition, an interior material 44 is attached to the vehicle interior side of the support member 40.

  With this configuration, as in the first embodiment described above, the visibility from the driver's seat can be improved, pedestrians and passengers can be protected, and the conventional windshield can be attached to the vehicle 2. The windshield 10 can be bonded to the vehicle 2 using an apparatus (equipment in a conventional production line). Further, when the windshield 10 is stored or transported, the side glass 16 can be folded with the intermediate film 18 with respect to the front glass 14 to make it flat and compact so that the windshield 10 can be stored without taking up storage space. In addition, more can be transported at one time, workability is improved, and transport costs can be reduced.

  In the above example, the support member 40 is provided above the bent portion B of the front pillar 12, but the structure in which the windshield 10 is attached without providing the support member 40 may be used.

  In the above-described embodiment, the front glass portion structure in which the front pillar 12 is bent in a substantially S shape near the intermediate position on the vehicle lower side has been described. However, as shown in FIG. You may form over the full length.
