Description

[Detailed Description of the Invention] This invention relates to a side sill drainage structure for an automobile equipped with a sliding door.

A small van-type truck as shown in FIG. 1 is often provided with a sliding door on the side of the vehicle body for convenient loading and unloading of cargo. The part of side sill 1 where the sliding door is installed is
It has a structure as shown in Figure 2. The side sill 1 consists of a sill inner 2 and a sill outer 3, which are joined to each other at joining flange portions 2a, 3a and 2b, 3b provided above and below, respectively. Upper flange part 2a of sill inner 2
is joined to the lower flange portion 4b of the lower rail 4 on which the roller of the sliding door slides, and the upper flange portion 4a of the lower rail 4 is joined to the flange portion 5a of the floor 5.
It is joined with.

When loading and unloading work with the sliding door open when it is raining, the rain falls on the side sill 1 and the lower rail 4, and rainwater accumulates inside the lower rail 4. In order to drain this water, conventionally, the lower flange portion 4b of the lower rail 4
A part of the is recessed inward to form a recess 4c, and the third
As shown in the figure, water was drained through a drainage space 6 formed between this recess 4c and the upper flange 2a of the sill inner 2.

However, this drainage space 6, which communicates with the outside, has an inconvenient aspect because, while performing the function of draining water, it also allows dust and noise to enter the room from the outside.

The purpose of this invention is to provide a side sill drainage structure that has an improved drainage space that does not allow dust or sound to enter.

The side sill according to this invention, as shown in FIG. 4, for example, has recesses 2c and 4c that are folded over each other and recessed inward at a part of the joint flange parts 2a and 4b between the sill inner 2 and the lower rail 4, and As shown in FIG. 5, there is water between the recess 2c and the joint flange 3a of the sill outer 3, between the sill inner 2 and the sill outer 3, and between the inner lower joint flange 2b and the outer lower joint flange 3b. from between the recess 2c and the joining flange 2a, through between the sill inner 2 and the sill outer 3, and between the inner lower joining flange 2b and the outer lower joining flange 3b, and further between the inner lower joining flange 2b and the outer sill. A drainage space 6 is formed between the lower joint flange portions 3b to drain water to the outside of the side sill. Therefore, water accumulated in the lower rail 4 flows out of the side sill 1 through this drain space 6.
Since this drainage space 6 is not directly open to the outside, dust, noise, etc. do not enter the vehicle interior from the outside through this space 6.

As described above, the side sill drainage structure invented by this invention can drain the water accumulated on the lower rail and at the same time prevent dust and sound from entering from the outside, making it extremely practical. A water drainage structure can be realized.

Claims (1)

[Scope of utility model registration request] In an automobile having a lower rail for a sliding door on the upper part of a side sill consisting of a sill inner and a sill outer, the upper parts of the sill inner and the sill outer are respectively extended upward to form an inner joint flange part and an outer joint flange part. , both joining flange parts are joined, and a part of the inner joining flange part is recessed inward in the vehicle width direction to form a recess between both joining flange parts, and the cross section is approximately U-shaped and extends in the vehicle width direction. A lower rail is provided that forms the opening and is arranged along the longitudinal direction of the vehicle, and the outer edge of the lower surface of the lower rail in the vehicle width direction hangs downward to form a lower rail joint flange. A drainage structure for a side sill, wherein the inner joint flange portions are joined to each other, and a drainage space communicating from the inside to the outside is formed at the lower end of the side sill consisting of the sill inner and the sill outer.
