Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the cowl structure of an automobile, and particularly relates to measures for alleviating the impact force on the front part of the passenger compartment and strengthening the support strength of the windshield.

(Prior Art) Conventionally, as a structure of a cowl part of an automobile, for example, as disclosed in Japanese Utility Model Application Publication No. 60-192973,
The two front pillars located on the left and right sides of the front of the vehicle are connected by a glass support member that extends in the vehicle width direction and has a substantially uniform cross-sectional shape over the entire cross section, thereby increasing the support strength of the windshield and increasing the strength of the vehicle. A generally known structure is one that attempts to ensure the strength of protection inside the room.

(Problems to be Solved by the Invention) However, since the above-mentioned conventional vehicle has a substantially uniform cross-sectional shape in the vehicle width direction, there are the following problems.

In other words, as a recent trend in automobile design, the windshield has been formed in a shape that bulges out and curves forward, and the cowl has also become lower as a result of lower vehicle bodies. The distance to the glass support member is becoming shorter. Therefore, if a strong impact is applied to the front of the vehicle, such as during a head-on collision,
A heavy engine tends to collide with the glass support member that supports the lower edge of the windshield and its lower wall surface (front wall of the vehicle interior).

In this case, if the glass support member has a uniform cross-sectional shape across the entire width of the vehicle, as in the conventional case, its strength is also almost uniform, so the engine collides with the glass support member to a large extent. A problem arises in that the entire windshield comes off at once.

The present invention was developed in view of these points, and its purpose is to absorb and alleviate the impact force when an engine collides by reinforcing the strength of the glass support member and making only a part of it weak. However, the purpose is to increase support rigidity to prevent damage to the entire glass support member and ensure support for the windshield.

(Means for solving the problem) In order to achieve the above purpose, the solution of the present invention is as follows:
Two front pillars located on the left and right sides of the front of the vehicle interior, and a pillar installed between the left and right front pillars, curved in an arch shape toward the front of the vehicle body, and extending in the vehicle width direction;
The present invention is based on an automobile equipped with a glass support member that supports the lower edge of a windshield.

and an inter-pillar member disposed behind the glass support member and extending substantially linearly in the vehicle width direction to linearly connect the two front pillars; , two connecting members connecting the glass support member and the inter-pillar member are provided,
The glass support member between the two connecting members is configured to form a fragile portion.

(Function) With the above configuration, in the present invention, even if a heavy engine collides with the cowl at the front of the passenger compartment in the event of a frontal collision of a car, the glass support member connected to the wall of the cowl Among them, only the weak part between the two connecting members easily breaks and absorbs and alleviates the impact force, while the other parts of the glass support member are connected to the front pillar via the connecting member and the inter-pillar member. As a result, the support rigidity is increased, sufficient support strength for the windshield can be ensured, and the retention of the windshield can be improved. Furthermore, the above structure makes the steering holding portion strong, and vibrations of the steering wheel can be suppressed and prevented.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 3 show the main parts of the front part of the vehicle body of an automobile according to an embodiment of the present invention, in which 1 is a passenger compartment, 2 is an engine room formed in front of the passenger compartment, and 3 is the engine room. The engine is located at 1. Two front pillars 6, 6 formed in a closed cross-sectional shape are provided on the left and right sides of the front part of the vehicle interior 1, and between the left and right front pillars 6, 6, both ends are A glass support member 8 is provided which is connected to and supported by the glass support members 6 and 6, is curved in an arch shape toward the front of the vehicle body, and extends in the vehicle width direction.
A lower end portion of a windshield 7, which is formed to bulge out toward the front of the vehicle body, is supported by the glass support member 8 via an adhesive 9. The glass support member 8 includes an upper member 8a and a lower member 8.
b, the cross section 8d is closed except for the weakened part 8e, which will be described later.
The rear end of the upper member 8a extends rearward to a straight line connecting the front pillars 6, 6, and the upper surface of the rear end of the extension plate portion 8c is provided with the left and right ends. front pillar 6,6
The inter-pillar member 10 extending substantially linearly in the vehicle width direction linearly connects the extension plate portion 8c.
and are joined to form a closed cross section. The extension plate part 8c has a predetermined interval on the upper surface corresponding to the rear position of the engine 3 and is slightly wider than the width of the engine 3, and extends in the front-rear direction of the vehicle body, and connects to the inter-pillar member 10 and the glass support. member 8
Two connecting members 11, 11 connecting the two are joined together with the extension plate portion 8c to form a closed cross section. As a result of the above, the windshield 7
Below, a cowl portion 12 is formed between the front portion of the vehicle interior and the engine room 2 to which a steering column or the like is attached. Note that 15 is a dart top having an L-shaped cross section and whose upper end is joined to the lower surface of the rear end of the extension plate portion 8c; cowl front forming an air intake 18 to the ventilator, 1
Reference numeral 7 denotes a dart lower which is vertically provided on the lower surface of the front end of the dart upper 15 and whose lower end is connected to a floor panel (not shown).

In addition, as shown in FIG. 4, the glass support member 8 between the connecting members 11, 11 has only the upper member 8a and the lower member 8b is omitted, and has a closed cross-sectional shape. Weak part 8
It is formed in e.

Therefore, in the above cowl structure, the glass support member 8 is firmly connected to the left and right front pillars 6, 6 via the connecting members 11, 11 and the inter-pillar member 10, and the connecting members 11, 11 Since the glass support member 8 on the outside in the vehicle width direction has a closed cross-sectional shape and is directly connected to the front pillars 6, 6, the rigidity of the glass support member 8 is increased, while the two connection members 11, The glass support member 8 between the members 11 is configured to have a weak strength. Therefore, when the heavy engine 3 collides with the cowl portion 12 during a head-on collision of the vehicle, the fragile portion 8e of the glass support member 8, which is configured to be fragile,
Only the damage absorbs and cushions the impact force. In addition, in conjunction with this shock mitigation, connecting member 1
The closed cross section 8d portion of the glass support member 8, which is doubly connected to the front pillars 6, 6 via 1, 11 and the inter-pillar member 10, is difficult to damage. Therefore, the retention of the windshield 7 is improved.

Furthermore, by connecting the glass support member 8 of the cowl portion 12 to the front pillars 6, 6 via the connecting members 11, 11 and the inter-pillar member 10, the steering holding portion becomes stronger.
The steering vibration prevention effect is also improved as much as possible.
