Abstract

PURPOSE:To prevent exfoliation of the bond to a window glass in the event of collision by extending a detent member in the lower part of the back face of a support to support the bottom of window glass, and by installing a detent member to detain with the engaging member in the event of collision in such a way as protruding at the panel in the cowl part of the car. CONSTITUTION:When a cowl 11 is crushed with movement of an engine 16 in the A direction in the event of frontal collision, the panel 12 moves backward together with a detent member 10 to cause its detent part 10a to be engaged with a detent boss 7b. This gives a push to the bottom of an engagement member 7 to cause inclination. Thus a pulldown force is applied to the top of the engagement member 7, and a window glass 1 and a window glass support 2 are pulled down to cause the window glass 1 to be bent as shown by the solid line. Thereby the exfoliating action is made in the tensile direction with greater resistance against exfoliation to lead to suppression of bond exfoliation.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a window glass that maintains the supporting force of the window glass by preventing the adhesion of the window glass support portion from separating due to a collision or the like. This relates to the mounting structure.

(Prior art) Window glass for vehicles is manufactured by, for example,
As disclosed in Publication No. 16, it is common to support the window glass by adhering it with an adhesive, and in this case, when there is a head-on collision, the window glass support receives an impact, especially at the lower end of the window glass, and the adhesion occurs. If shearing force is applied to the window glass and the adhesive force between the window glass and the window glass support is weak, there is a risk that the adhesive between the window glass will peel off.

(Object of the Invention) The object of the present invention is to provide a window glass mounting structure that solves the above-mentioned conventional problems and prevents the adhesion of the window glass from peeling off in the event of a collision. be.

(Structure of the Invention) In order to achieve the above-mentioned object, the present invention is such that the lower end portion of the window glass is supported by the window glass support portion via an adhesive, and the lower end portion of the window glass support portion is supported from the back surface portion downwardly. An engaging member is provided that extends to the vehicle body panel forming a cowl below the lower end of the window glass, and is engaged with the engaging member when the vehicle body panel moves rearward due to a collision or the like. This is a window glass mounting structure in which a locking member having a locking portion is provided.

According to the above configuration, when the vehicle body panel forming the cowl portion is crushed by the impact and moves rearward during a frontal collision, the locking member provided on the vehicle body panel also moves rearward at the same time. The locking part engages with the lower end of the engaging member provided on the back side of the window glass support part and attempts to move the lower end of the engaging member rearward, but the engaging member is not connected to the upper end. is fixed to the back side of the window glass support, the lower end moves significantly backwards and becomes tilted, and the upper end acts to bend the fixed window glass support downward, causing the window glass support to bend. An attempt is made to bend the lower end of the window glass whose back surface is adhered to the window glass support part and the molding member holding the lower end of the window glass from the front side while holding the lower end part of the window glass downward. This downward bending force is mainly resisted by the trap 11 properties of the window glass and the window glass support, and the force that causes the window glass to peel off is small. This is significantly reduced compared to the shearing force that acts on the window glass adhesive part caused by the support part directly receiving the impact of a collision and moving backwards, and can prevent the window glass adhesive from peeling off. .

(Example) The present invention will be described below based on an example shown in the drawings.

FIG. 1 to FIG. 6 show an embodiment of this invention.
(1) is a window glass, the lower end of which is adhered to and supported by a window glass support part (2) with an adhesive (3). (4) is the dam member, and the window glass (1)
and the window glass support part (2) to prevent the adhesive (3) from flowing out to the storage room side. (5)
is a molding that holds down the lower end of the window glass (1) from the upper surface, and is attached to the window glass support part (2) by a fastening member (6).

(7) is a retaining member, which has a flange portion (7a) at the upper end and a retaining protrusion (7b) bent forward at the lower end, as shown in Fig. The flange part (7a) at the upper end is attached to the bracket (8) shown in FIG. 4, which is fixed to two places on the left and right sides of the back surface part, by a fastening member (9), and extends downward and is provided at two places on the left and right sides ( Reference numeral 10) denotes a locking member, which is made of an L-shaped plate and has an elongated hole-shaped locking portion (10a) near the upper end, and a cowl portion formed below the lower end of the window glass (1). Vehicle body panel (12) (which constitutes the bottom part of (11)
The lower end portions are attached to positions corresponding to the engaging members (7) by fastening members (13) at two locations on the left and right upper surfaces of the upper surface of the upper panel (Dance Upper Panel), and are provided so as to rise upward. The locking portion (10a) of the locking member (10) corresponds to the engagement protrusion (7b) of the retaining member (7).

(14) is a cowl cover that covers the upper opening of the cowl portion (11), and (15) is a bonnet that covers the upper part of the engine room so as to be openable and closable.

Assuming a head-on collision occurs in the normal state of Golden Brother 2,
As shown in Fig. 3, the engine (16) that is pushed by the collision and moves rearward crushes the cowl (11) in the direction of arrow A, and the body panel (12) that forms the bottom of the cowl (11) ), the locking part (10a) engages with the engagement protrusion (7b) at the lower end of the engagement member (7), and the engagement member (
7) By pushing the lower end backward, the lower end of this engaging member (ma) moves in the direction of arrow B and becomes inclined, giving a downward tendency to the upper end. Then, the upper end of the engaging member (7) tends to pull the lower end of the window glass (1) held between the window glass support part (2) and the molding (5) downward through the bracket (8). , this action tries to bend the window glass (1) from the normal state shown by the imaginary line to the state shown by the solid line, and the window glass support part (2) also acts in the direction of bending at the same time, and this bending The rigidity of the window glass (1) and the window glass support part (2) resists external forces.
At this time, the action of peeling off the adhesive between the window glass (1) and the window glass support part (2) is caused by the molding (5).
Since the lower end of the window glass (1) is held between the window glass support part (2), the tension becomes relatively small and acts in the tensile direction where peeling resistance is high. This means that if the present invention is not carried out, the engine (16) moving backward due to a collision will push the cowl part (11) rearward, causing the window glass support part (2) to retreat and bond to the window glass (1). The force in the shearing direction that acts directly in the direction of arrow C, which has relatively low peeling resistance, can be significantly reduced, and the adhesive peeling of the window glass (1) caused by a head-on collision can be significantly reduced.

(Effects of the Invention) According to the window glass mounting structure according to the present invention described above, it is possible to reduce the force in the shearing direction that acts on the adhesive part at the lower end of the window glass caused by a head-on collision, and to reduce the impact force caused by this collision. Part of the rigidity in the bending direction of the window glass and the window glass support part is supported, thereby reducing the force that acts on the adhesive peeling of the window glass and maintaining the supporting force of the window glass. .
