Description

  The present invention relates to a vehicle windshield structure that can reduce damage to a pedestrian during a collision.

  A windshield is provided in front of the vehicle interior space. Front pillars are provided on both sides of the windshield, and the left and right ends of the windshield are held by the front pillar.

  The front pillar is provided between the rear of the front portion of the vehicle and the front end of the roof portion, and supports the front end portion of the roof portion and has a predetermined strength to ensure a occupant's living space in the event of an emergency. Is formed. Therefore, since the front pillar has a relatively large cross section and is disposed in front of the driver in the passenger compartment, a blind spot may be generated obliquely in front of the driver.

  In view of this, there has been invented a windshield whose purpose is to move the position of the front pillar to the rear side of the vehicle and improve the field of view in front of the vehicle. For example, in International Publication WO2002 / 100671, a windshield is formed continuously and integrally from the front of the vehicle to the side of the vehicle in a substantially U shape, and the front pillar is moved to the rear of the vehicle. An example in which the forward field of view is improved is described.

In addition, since the strength of the front pillar is ensured, if an accident occurs in which the pedestrian comes into contact with the front pillar, there is a risk of serious damage to the pedestrian. It is considered effective to move the position of the vehicle to the rear of the vehicle.
WO2002 / 100671

  However, in many cases, the windshield of the vehicle is now made of laminated glass. Laminated glass has a property that it is difficult to bend with a small radius of curvature because it is formed by bonding two sheets of glass with a resin film in between. Therefore, it was practically impossible to inexpensively mass-produce the above-described U-shaped windshield using laminated glass.

  Even if a U-shaped windshield is adopted, the bent part becomes stronger than the other parts, and the part located on the side of the vehicle is not easily broken against a collision from the front of the vehicle. When an accident occurs such that the pedestrian comes into contact with the bent portion of the windshield, the impact cannot be absorbed effectively and the pedestrian may be damaged. That is, even if the position of the front pillar is moved backward, it is considered that the effect is very thin.

  An object of the present invention is to solve the above-mentioned problems and to provide a windshield structure for a vehicle that has good front visibility and can further reduce damage to a pedestrian even in the event of an accident.

  In order to solve the above-described problems, the present invention has a vehicle windshield structure configured as follows.

1. A front glass that covers a front surface of an interior space of a vehicle, and a side glass that is connected to left and right edges of the front glass via molding parts and arranged along the traveling direction of the vehicle. A crushing member that abuts against the side glass and crushes the side glass when a predetermined load or more is applied from the front of the vehicle is provided inside the molding part in which the glass and the side glass are connected.

2. A vehicle windshield structure according to any one of claims 1 and 2, wherein the crushing member extends from a reinforcing member provided in the molding portion, and the tip thereof is directed to the end surface of the side glass.

The vehicle windshield structure according to any one of claims 3 and 1, wherein the crushing member is attached to an end face of the side glass.

4. The windshield structure for a vehicle according to any one of 1 to 3, wherein the side glass is a tempered glass.

5. The windshield structure according to any one of 1-4, wherein the front pillar of the vehicle is bent so as to follow an edge of the side glass on the vehicle rear side at least in a portion where the side glass is disposed. The rear edge of the vehicle is fixed to the front pillar.

  The vehicle windshield portion structure according to the present invention has the following effects.

  Since the windshield is composed of the front glass and the side glass that is connected to the left and right edges of the front glass via the molding parts, the windshield is placed on the front side of the front pillar, so by any chance Even if it collides with the front pillar, it is possible to avoid contact with the front pillar, and even if it makes contact with the molding portion of the windshield, the degree of damage can be greatly reduced as compared with the front pillar.

  Furthermore, since a crushing member that crushes the side glass when a predetermined load or more is applied to the molding part from the front side of the vehicle, the side glass is easily crushed by the crushing member, resulting in more damage to the pedestrian. It can be effectively reduced.

  In other words, even if the front pillar is bent or moved to the rear side of the vehicle to reduce the blind spot due to the front pillar, a substantially U-shaped windshield can be easily formed, and the front side of the driver seat or front passenger seat can be It is possible to improve the visibility of the pedestrian and reduce the impact on the pedestrian due to the collision.

  An embodiment of a windshield structure for a vehicle according to the present invention will be described with reference to the drawings. FIG. 1 shows a vehicle 2 provided with the windshield 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). A windshield 10 attached between the rear end of the front portion 4 and the front end of the roof portion 8 is provided in front of the passenger compartment 6. A door 9 is provided on the side of the passenger compartment 6 and a rear door (not shown) is provided on the rear side.

  In front of the vehicle 2, front pillars (also referred to as A pillars) 12 are provided on the left and right sides between the rear end of the front portion 4 and the front end of the roof portion 8. The front pillar 12 is a structural member that forms the skeleton of the vehicle 2, supports the front portion of the roof portion 8, and fixes both end portions of the windshield 10. Normally, the front pillar 12 extends to a floor (not shown) provided at the lower end of the vehicle 2. Here, a member between the front portion 4 and the roof portion 8 is referred to as a front pillar, and the front pillar. When the upper half portion of 12 is referred to, the upper half portion of the front portion 4 and the roof portion 8 is defined as a boundary.

  The front pillar 12 extends obliquely downward from the front end of the roof portion 8 toward the front in the traveling direction of the vehicle 2 and bends downward in the vicinity of the intermediate position in the height direction. The lower end is connected to the rear end portion of the front portion 4. That is, the front pillar 12 is formed in a substantially S-shape including an upper half B formed substantially flat and a lower half C bent.

  As shown in FIG. 2, the windshield 10 includes a front glass 14 that is attached so as to cover the front surface of the vehicle compartment 6 (interior space) of the vehicle 2 and a side glass 16 that is attached along the traveling direction A of the vehicle 2. The front glass 14 and the side glass 16 are connected by a molding part 20 and fixed integrally.

  The front glass 14 is made of laminated glass used for a normal vehicle windshield, and has a resin intermediate film 18 between the two front and back glasses as shown in FIG. The intermediate film 18 is, for example, a PVB (polyvinyl butyral) resin film. The side glass 16 is made of tempered glass.

  Specifically, in FIG. 1, the front glass 14 is formed between a front end of the roof portion 8 and a rear end of the front portion 4, and a line connecting the left end portion of the front end of the roof portion 8 and the rear left end portion of the front portion 4. The side glass 16 is a portion surrounded by a line connecting the right end portion of the front end of the roof portion 8 and the right end portion of the rear portion of the front portion 4, and the side glass 16 includes left and right end edges of the front glass 14 and the lower half portion of the front pillar 12. It is a part surrounded by C.

  The molding part 20 is comprised from the reinforcement member 22 and the resin part 24, as shown in FIG. The reinforcing member 22 is an elongated metal member having an arcuate cross-sectional shape, and protrusions 3 as crushing members are formed at predetermined intervals in the center in the width direction. The protrusion 3 is a triangular protrusion as shown in FIG. 4, and is formed so that the tip thereof faces the end surface of the side glass 16 when the reinforcing member 22 is fixed inside the molding portion 20. For example, the protrusion 3 is formed by pressing.

  The resin portion 24 fixes the front glass 14 and the side glass 16 including the reinforcing member 22 at a predetermined angle. For example, the resin portion 24 is held in the mold in a state in which the front glass 14 and the side glass 16 are abutted at a predetermined angle, and a resin material is injected into the mold to be molded.

  The material, strength, thickness and width of the reinforcing member 22 and the resin portion 24 or the shape and size of the protrusions 3 and the installation interval are such that the molding portion 20 has a desired strength and the front glass 14 and the side glass 16 When the pedestrian comes into contact with the molding part 20 from the front side of the vehicle, the side glass 16 is selected or set so as to be crushed with a predetermined load or more.

  The windshield 10 is attached to the vehicle 2 with an adhesive applied to the periphery. That is, the upper edge of the front glass 14 and the front end portion of the roof portion 8, the lower edge of the front glass 14 and the rear end portion of the front portion 4, the upper half portion of the left and right end edges of the front glass 14, and the upper half portion of the front pillar 12. B. It is bonded and fixed by an adhesive applied to each of the rear edge of the side glass 16 and the lower half C of the front pillar 12.

  That is, the front pillar 12 is along the upper half of the left and right edges of the front glass 14 of the windshield 10, and is along the vehicle rear side edge of the side glass 16 at least in a portion where the side glass 16 is disposed. Thus, the side portion of the windshield 10 is supported. In FIG. 5, the cross section of the junction part of the upper half part of the right-and-left edge of the front glass 14 and the upper half part B of the front pillar 12 is shown.

  Next, the operation of the windshield 10 will be described.

  In the vehicle 2, the molding part 20 is provided along the lower half C of the left and right edges of the windshield 14 in the windshield 10, so that no blind spot is generated by the front pillar 12, and the driver diagonally forwards. Can improve the visibility. Also, even if a pedestrian comes into contact with any one of the left and right molding parts 20 of the windshield 10, the molding part 20 can be easily formed by the impact force with which the pedestrian comes into contact because the molding part 20 has low rigidity. Can be crushed and reduce damage to pedestrians.

  Further, since the reinforcing member 22 is provided with the protrusion 3 as a crushing member, when the molding part 20 is deformed by receiving an impact from the front side of the vehicle, the protrusion 3 immediately comes into contact with the end surface of the side glass 16 and the protrusion 3 The side glass 16 is crushed at the tip. Therefore, the side glass 16 can be formed firmly, for example, by increasing its thickness. On the other hand, when an impact is applied, the side glass 16 is easily crushed with a small force, and the damage to the pedestrian can be reduced efficiently.

  Further, since the windshield 10 is formed of laminated glass having at least the front glass 14 having the intermediate film 18, even if an accident occurs and the occupant collides with the windshield 10, the occupant is prevented from jumping out of the vehicle. The occupant can be held securely.

Moreover, moderate elasticity is obtained by the intermediate film 18, which can reduce damage to the occupant due to collision with the windshield 10.

  The side glass 16 employs tempered glass that is easily crushed against a pedestrian contact and can absorb impact more effectively. Also good.

  Next, another example of the crushing member will be described with reference to FIG. The crushing member 30 is an elongated metal piece, and has leg portions 34 on both sides of the main body portion 32 in a U-shape, and a protrusion 36 is formed on the main body portion 32 facing the crushing member 30. The opposing leg portions 34 are formed at intervals that sandwich the side glass 16 from the thickness direction with an appropriate elastic force. Further, gaps 38 are provided between the leg portions 34, and the crushing member 30 is formed to be freely bent by the gaps 38, and when the molding portion 20 is formed, the injected resin material is sufficient for the side glass 16. It comes to adhere to.

  The protrusion 36 is formed in a triangular shape that presses the main body 32 and rises substantially perpendicularly to the main body 32. The tip of the protrusion 36 is formed so as to face the center of the end surface of the side glass 16 in the thickness direction when the crushing member 30 is attached to the edge of the side glass 16.

  The windshield 10 is formed as follows. The side glass 16 is sandwiched between the legs 34, and the crushing member 30 is assembled to the edge of the side glass 16 with a slight gap between the protrusion 36 and the end surface of the side glass 16. Then, the side glass 16 is abutted against the front glass 14 in a state where the crushing member 30 is assembled, a reinforcing member (not shown) is disposed at the abutting portion, and a molding material 20 is formed by, for example, injecting a resin material in a mold. . Thus, the front glass 14 and the side glass 16 are fixed integrally, and the windshield 10 is formed. When the windshield 10 is formed, the windshield 10 is bonded and fixed to the front of the vehicle 2.

  If a pedestrian contacts the molding part 20 of the vehicle 2 due to a collision or the like and the molding part 20 is deformed and presses the crushing member 30, the leg part 34 of the crushing member 30 slides against the side glass 16, and the side glass 16 is fitted deeply. Then, the protrusion 36 bites into the end surface of the side glass 16 and crushes the side glass 16.

  When the crushing member 30 is formed in this way, the side glass 16 can be easily crushed when a pedestrian collides as described above, and damage to the pedestrian can be reduced. Since the crushing member 30 can be directly fixed to the edge of the side glass 16, no displacement occurs, and the mounting operation is facilitated. Further, it is not necessary to form protrusions on the reinforcing member.

  The present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
