Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a waterproof structure for a module door, in which parts to be arranged in a door are attached in advance to a module base, and in a vehicle body assembly line, the door assembly is completed simply by assembling the module base to the door.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an automobile door has a structure in which a slit for raising and lowering a wind panel is formed on the upper side, and it is inevitable that water enters through the slit. For this reason, the work hole of the door inner panel is waterproofed by adhering the seal screen after completion of assembling the components in the door. The water that has entered the door is drained out of the door through a drain hole formed in the lower end of the door, so that the water does not stay in the door.
[0003]
Further, as shown in FIG. 4 and FIG. 5 in recent years, components such as a window regulator 102 mounted in the door 100 are attached in advance to the module base 104, and the above-described components are assembled in the vehicle body assembly line. 2. Description of the Related Art A module type automobile door that can complete assembly of components in the door 100 by simply attaching the base 104 to the door 100 is known. When the module base 104 is attached to the door inner panel 106, the module base 106 is attached to the work hole 108 opened in the door inner panel 106 so as to cover from the outside via the seal material 110.
[0004]
In such a module door 100, the infiltrated water w travels through the window regulator 102 and drops onto the module base 104. At this time, a gap c necessary for the elastic deformation of the sealing material 110 exists between the peripheral edge 104a of the module base 104 and the lower edge 108a of the work hole 108 of the door inner panel 106. The groove portion 112 is configured with the material 110 as the bottom, and the water w flowing into the groove 110 stays in the groove portion 112.
[0005]
Therefore, in order to prevent the water w from staying, a drain hole 108b is formed in the lower edge 108a of the work hole 108 of the door inner panel 106 in the groove portion 112, and the water w that has entered the groove portion 112 is removed. It has a structure in which it escapes to the inside of the door 100 and drains out of the door 100 from a drain hole 114 formed in the lower end of the door 100 (see Japanese Utility Model Laid-Open No. 1-73017 as a similar technique).
[0006]
[Problems to be solved by the invention]
However, since the drain hole 108b cannot be set so large in terms of space, dust tends to accumulate. If the drain hole 108b is clogged with dust or the like, the sealing material 110 is always immersed in the water w, which causes deterioration. The deteriorated sealing material 110 has a reduced sealing performance, and there is a possibility that water w leaks to the vehicle interior side.
[0007]
The present invention has been made to solve the above-described problems, and includes a door inner panel, a module base, and a sealing material so that water does not leak into the vehicle compartment even if water flows into the module door. It is intended to provide a waterproof structure for an automobile module door with improved waterproofness by making the structure so that water does not enter the groove and preventing the sealing material from being immersed in water, thereby improving the durability of the sealing material. .
[0008]
[Means for Solving the Problems]
The invention according to claim 1 is that a module base is arranged at a position where a work hole formed in the door inner panel is closed from the indoor side, and the module base and the door inner panel face each other with a gap therebetween, In the clearance structure of the automotive module door, in which the seal material is disposed at a position where the working hole side opens in the gap , and a groove portion having an opening on the upper side is formed below the working hole , A waterproof cover having a length equivalent to the left and right width of the opening of the working hole is attached to the outer surface of the module base casing, and the waterproof cover is disposed on the upper side so as to cover the opening of the groove and not enter the groove. And has a flange protruding into the working hole.
[0009]
According to the invention of claim 1, it is possible to prevent water from entering the groove by covering the opening of the groove having an opening on the lower side with the waterproof cover on the lower side of the work hole where water may stay, The durability of the sealing material arranged in the groove is improved and the leakage of water into the vehicle compartment can be prevented, so that the waterproofness of the module door is improved.
[0010]
According to a second aspect of the present invention, the waterproof cover is formed of an elastic member that can be elastically deformed.
[0011]
According to the invention described in claim 2, since the waterproof cover is formed of an elastic member that can be elastically deformed, the waterproof cover can be easily deformed and attached even if the mounting position is changed in relation to other components. Therefore, it is possible to contribute to cost reduction without increasing the types of parts.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 denotes an automobile module door. The module door 1 is formed in a hollow shape by a door outer panel 2 and a door inner panel 3.
[0013]
Reference numeral 4 denotes a module base that is press-formed from a steel plate. The module base 4 is formed in a size sufficient to close the working hole 5 opened in the door inner panel 3 and is fastened to the door inner panel 3 with bolts 6.
[0014]
As shown in FIG. 3, the seal member 7 is bonded to a bead 4 c formed on the entire peripheral edge portion 4 b of the outer side surface 4 a of the module base 4.
[0015]
A seal material 7 is sandwiched between the lower edge 5 a of the work hole 5 opened on the side surface 3 a of the vehicle interior of the door inner panel 3 and the bead 4 c of the module base 4. A gap C exists between the lower edge 5 a of the work hole 5 of the door inner panel 3 and the peripheral edge 4 b of the module base 4. Grooves 8 are formed on both sides with the peripheral edge 4b of the module base 4 and the lower edge 5a of the work hole 5 of the door inner panel 3 on both sides with the sealing material 7 as the bottom.
[0016]
A drain hole 5 b is formed at the lower edge 5 a of the work hole 5 of the door inner panel 3 at the height of the sealing material 7. Thereby, the water W that has entered the groove 8 flows out into the module door 1 from the drain hole 5b before it stays. A drain hole 1b is formed in the bottom 1a in the module door 1, and the water W that has entered the module door 1 is drained out of the module door 1 through the drain hole 1b.
