Abstract

PURPOSE:To prevent a door from getting incapable of opening at the time of back surface collision by providing a stopper protruded back from a rear end of a front door window panel at a rear end part of a front door panel. CONSTITUTION:A rigid stopper 14 of metal in the form of a hollow box is provided at a rear end part 4 of a front door panel 3 a little protruded back R from a rear end 6 of a front door window panel 5. If a car body is deformed at the time of back surface collision to move a rear door outer panel 12 forward F, a forward protruded part 13 is applied to the stopper 14 to be prohibited from advancing. The rear door outer panel 12 is thus prevented from biting a recess 10 of the front door panel 3, thereby the door is prevented from becoming incapable of opening.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a door structure for a satsuru door vehicle.

[Conventional technology]

As side doors for four-door and five-door cars with a sashless structure (hereinafter referred to as sashless door cars), the ones shown in Figures 4 to 7 are known (for example,
(Refer to Publication No.-85315).

The door structure of such a satsuru door car is such that the rear end 6 of the front door window panel 5 protrudes from the upper part A of the rear end 4 of the front door panel 3, which corresponds to the front end 2 of the rear door panel l. ing. That is,
The surface shape of the rear end portion 4, specifically the surface shape of the rear end surface of the front door inner panel 7, is almost a smooth surface shape, and around the upper part A, the rear end 6 of the front door window panel 5 is rearward from there. A recess 1 like a "valley" is formed between the joint 9 of the front door inner panel 7 and the front door outer panel 8 and the rear end 6 of the front door window panel 5 that projects rearward.
This will result in a value of 0.

In the figure, 11 indicates a weather strip, 12 indicates a rear door outer panel, 13 indicates a front protruding portion of the rear door outer panel, arrow R indicates rear, and arrow F indicates front.

[Problem to be solved by the invention]

Therefore, if the rear door panel 1 moves forward due to the deformation of the vehicle body during a rear-end collision, the forward protruding portion l3 of the rear door outer panel 12 located at the front end 2 of the rear door panel l will move toward the rear end 4 of the front door panel 3. Upper part A
There was a risk that the blade would dig into the recess 10 at some point. Conventionally, as a countermeasure to this problem, various reinforcements have been applied to the vehicle body to prevent it from being deformed in the event of a rear-end collision, but these tend to increase weight and cost.

This invention was made in view of this problem, and by implementing a simple method that does not increase weight or cost, the vehicle body deforms in the event of a rear-end collision, causing the rear door outer panel to move forward and creating a recessed area. It attempts to solve the problem by preventing it from entering even if it tries to get inside.

[Means to solve the problem]

To this end, in the present invention, a stopper is provided at the rear end of the front door panel and protrudes rearward from the rear end of the front door window panel at the rear end of the front door panel.

[Effect]

This stopper is located at the rear end of the front door panel and protrudes rearward from the rear end of the front door window panel at the rear end of the front door panel, so in the event of a rear collision, the vehicle body deforms and the rear door outer panel Even if it moves forward, the forward protruding portion of the rear door outer panel hits this stopper and is prevented from moving further, so that the upper part of the rear end of the front door panel does not dig into the recess.

〔Example〕

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3. For convenience, the same or common parts as shown in FIGS. 1 to 7 are designated by the same reference numerals, and redundant explanations will be omitted as much as possible.

The rear end 4 of the front door panel 3 is provided with a stopper l4 made of a rigid hollow box-shaped metal material, for example, and this stopper 14 slightly protrudes toward the rear R from the rear end 6 of the front door window panel 5. exhibiting a condition. That is, this stopper 14
A substantially smooth surface-shaped portion of the front door inner panel 7 corresponding to the rear end portion 4 and near the rear upper portion A of the front door waist portion W, the rear end of the front door window panel 5 at the upper portion A As shown in FIG. 2, the stopper l4 is installed at a portion where the front door window panel 5 above the smooth-shaped portion protrudes from the rear end 4 of the front door panel 3. lower and at least outside the front door window panel 5. And the second
When viewed from the arrow X direction in the figure, the stopper 14 looks like a recess 1.
0 is in a closed state (see Figure 3).

Therefore, even if the vehicle body is deformed at the time of a rear collision and the rear door outer panel l2 tries to move forward F, its forward protruding part 13 hits the stopper l4 and is prevented from moving further, and as a result, it does not dig into the recess 10.

In the above explanation, the stopper 14 is provided at only one location, but it may be provided at multiple locations, and the location is limited as long as the stopper 14 is provided at a location that can prevent excessive forward movement of the forward protruding portion 13 of the rear door panel l2. I don't receive it.

Further, the stopper 14 may be formed by protruding a part of the front door inner panel 7.

〔Effect of the invention〕

Since the door structure of the satsure-less door vehicle according to the present invention is as described above, even if the vehicle body deforms in the event of a rear collision and the rear door outer panel moves forward and attempts to enter the recess, the stopper can prevent it. Additionally, installing a stopper is a simple method that does not increase weight or cost, but it can solve the problem of the door not opening in the event of a rear collision, increasing the safety of the occupants, and is beneficial. There are a lot of things here.
