Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cowl structure that constitutes a part of an automobile body, and in particular, to a cowl structure that is a part of an automobile body. This allows for suitable processing.

[Prior Art] A cowl is a vehicle body structural member disposed at the bottom of a front window and connected to left and right front pillars of the vehicle body, and an outside air inlet for a ventilator is provided in this portion. This cowl has a structure shown in FIG. 2. That is, as shown in the figure, a cowl top 1 with a substantially U-shaped cross section that opens upward extends in the vehicle width direction, and both ends thereof are connected to left and right front pillars of the vehicle body (not shown). is covered by a louver 2 that also extends in the vehicle width direction, and a rear end 2a of the louver 2 is joined to a front end 3a of the windshield 3. A protector 4 is inserted at the joint between these two members 2 and 3, thereby preventing rainwater and the like from entering from the joint.
Further, in the bottom wall 1a of the cowl top 1, a ventilator outside air inlet 1b is formed at a position offset in the vehicle width direction from the opening (not shown) of the louver 2, and below this inlet 1b is a broken line. A blower 5 is arranged as shown in . Here, in order to prevent rainwater etc. that have entered the cowl from entering the blower 5 side from the inlet 1b, this inlet 1 is
A rising portion 6 is arranged on the outer periphery of b, and rainwater etc. that have entered the cowl are flowed outward in the vehicle width direction on the cowl top bottom wall 1a, and are drained from the side of the vehicle body to the outside of the vehicle. It is beginning to be excreted.

[Problems to be solved by the invention] However, in the case where the louver 2 and the windshield 3 are joined in this way, the waterproofing of the joint is achieved only by the protector 4, so there is no possibility of water leakage from this part. It is difficult to completely prevent infiltration of rainwater, etc. When rainwater enters from such a part, if the part is located above the outside air inlet 1b as shown in FIG. This will cause damage due to dripping.

An object of the present invention is to provide a cowl structure that eliminates the problems of the prior art.

[Means and effects for solving the problem] To this end, in the present invention, the portion on the louver side at the joint between the louver of the cowl and the windshield extends from the bottom of the windshield toward the rear of the vehicle body. This forms a receiving part (flow channel) below the joint of both members to receive the water that enters from this joint, and prevents the water from entering the vehicle body from the ventilator outside air inlet. That's what I do.

[Example] An example of the present invention will be described below with reference to FIG. In the description, the same parts as in FIG. 2 will be described using the same reference numerals.

In the figure, 1 is a cowl top, and 11 is a louver. The louver 11 covers most of the opening of the cowl top from the front end of the vehicle body to the rear end of the vehicle body. This louver 1
A side wall 11b is formed near the lower surface of the front side 11a of the vehicle body, and extends downwardly while being inclined toward the rear side of the vehicle body.The lower end of this side wall 11b is a bottom wall 11c that extends substantially horizontally toward the rear of the vehicle body. Furthermore, the tip of this bottom wall 11c is a side wall 11 bent upward.
d. The above end portion 11a, side wall 11b
A groove 12 that opens diagonally upward toward the rear of the vehicle body is formed by the bottom wall 11c. This groove 1
A protector 13 whose upper end wraps around the upper side of the end portion 11a is attached to the interior of the windshield 2, and the front end 3a of the windshield 3 is attached to the groove 12 with the protector 13 sandwiched therebetween. has been done.

Here, the above-mentioned side wall 11b, bottom wall 11c and side wall 11d are formed over almost the entire width in the vehicle width direction, and are located on both ends of the bottom wall 11c or side wall 11d in the vehicle width direction, or on the cowl top bottom wall 1a. In a part sufficiently far away from the outside air inlet 1b,
A notch (not shown) is formed. Therefore,
Rainwater, etc. that has entered onto this bottom wall 11c from outside the vehicle body is absorbed by the bottom wall 11c and the side walls 11b, 1 on both sides thereof.
1c, flows down from the above-mentioned notch onto the cowl top bottom wall 1a, and is then discharged from the bottom wall 1a to the outside of the vehicle.

Therefore, in this embodiment configured in this way, the water that enters through the joint between the louver 11 and the windshield 3 accumulates on the flow channel 14 and flows through this flow channel 14 in the vehicle width direction. It is ejected from the vehicle. In other words, the infiltrated water enters the outside air inlet 1b.
It is possible to reliably prevent the water from directly entering the blower 5 side through the air.

In the above-described embodiment, the flow channel 14 is formed over almost the entire width in the vehicle width direction, but it goes without saying that it may be formed only in the portion above the outside air introduction port 1b. Furthermore, in the above example, the intruding water is caused to flow in the vehicle width direction by the flow channel 14; however,
For example, the infiltrated water may be allowed to flow onto the side wall surface 1c of the cowl top 1 on the rear side of the vehicle body, and flow down on this side wall surface 1c.

[Effects of the invention] As explained above, according to the invention, a flow channel is formed below the joint between the louver and the windshield in the cowl structure, and rainwater etc. that have entered from the joint are drained through this flow channel. Therefore, it is possible to reliably prevent water from entering the joint portion from entering the inside of the vehicle body through the outside air inlet formed in the bottom wall of the cowl top.
