JPH0263921A - Stopping device for car slide door - Google Patents

Abstract

PURPOSE:To prevent generation of a torque when a slide door for a car, wherein the upper edge of slide door is situated behind the lower edge, is closed, by furnishing the slide door at its upper edge with a stopper which is detained with the car body when it is shut. CONSTITUTION:A car body 1 equipped with a slide door 2 has a side panel 3, in which an opening 4 for installation of the slide door 2 is formed as a getting-on/off opening. An upper stage guide rail 51 and a lower stage guide rail 53 are furnished at an upper edge 4a and a lower edge 4c of this opening 4, and a middle stage guide rail 52 is installed at a side panel behind a rear side edge 4b. Therein a detent part 19 is formed at the fore panel part of the front end part 5a of the guide rail 51, while a stopper 20 to be detained with this detent 19 is installed in the front part of a guide roller 131 of slide door 2. This hinders torque generation at the top tip of the slide door 2 when the door is shut.

Description

[Detailed description of the invention] a. Industrial application field The present invention relates to a stopping device for an automobile sliding door.

b. Conventional technology The sliding doors installed in automobiles are of the rectangular type used in wagon cars as shown in Figure 8, and the pentagonal type with short upper sides used in passenger cars as shown in Figure 9. There is a type.

The sliding door 100 has upper, middle and lower guide rails 101 and 102 provided on the side sills and side panels of the vehicle body.
, 103 are engaged with guide rollers 104 via upper, middle, and lower support arms (not shown).

C1 Problem to be solved by the invention When the sliding door lOO of a wagon is closed,
Since the upper and lower ends of the sliding door 100 hit the shut stopper 105 at the same time, the force (inertial force) when closing the door and the shutoff when stopping the door are balanced as shown by the arrows in FIG.

On the other hand, since the lower half of the sliding door 100 of a passenger car hits the shaft stopper 106, an inertial force acts on the upper support arm as shown by the arrow in FIG. 11, causing a force to rotate forward.

Therefore, there is a risk that the support arm may hit the end or flange of the guide rail 101, damaging the roller lQ4 or bending the support arm.

SUMMARY OF THE INVENTION An object of the present invention is to provide a stop position for an automobile sliding door that can solve the above problems and improve the durability of the sliding door.

d. Means for Solving the Problems In order to solve the above problems, the present invention provides a stopping device for a sliding door for an automobile in which the upper side of the sliding door is located rearward than the lower side. A stopper is provided that locks on the vehicle body when the door is opened, and the stopper is brought into contact with the vehicle body before the upper guide roller etc. hits the vehicle body to prevent the sliding door from being scratched due to the inertial force of the sliding door. This is what I did.

e. Operation When closing the sliding door, the lower half of the sliding door is locked to the shaft stopper on the vehicle body side.

Inertial force acts on the sliding door, and rotational force acts forward on the top of the sliding door.

At this time, a stopper provided on the upper side of the sliding door is latched to the vehicle body and stopped, thereby preventing injury to the upper support arm, etc.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Figure 2 is a perspective view showing the sliding door in a closed state;
The figure is a conceptual diagram showing the process of opening the sliding door, Figure 4 is a cross-sectional perspective view taken along line A-A in Figure 2, and Figure 5 is a cross-sectional view taken along line A-A in Figure 3.
6 is a sectional perspective view taken along the line A, FIG. 6 is a sectional view taken along the line BB in FIG. 3, and FIG. 7 is a perspective view showing a stopper portion.

1 to 3, reference numeral 1 denotes an automobile body equipped with a sliding door 2, and an opening 4 for attaching the sliding door 2 is formed in a side panel 3 as an entrance/exit. The sliding door 2 has the same shape as a normal passenger car door, and the length β of the upper side is shorter than the length m of the lower side, and the front of the upper side is formed obliquely.

An upper guide rail 51 and a lower guide rail 53 are provided on the upper edge 4a and lower edge 4c of the opening 4, respectively, and upper and lower guide rails 5. , 5: A middle guide rail 5z is provided in the same direction as l.

Above upper guide rail 5. As shown in FIGS. 4 to 6, the roof side panel portion 3b from the upper edge 4a of the opening 4 to the rear is formed to be flush with the upper edge 4a, and the roof side panel portion 3b extends from the upper edge 4a of the opening 4 to the rear. Upper guide rail5. This is an extension of the . This allows the length of the upper guide rail 51 to be reduced to the length of the lower guide rail 5. and set to the same length.

Reference numeral 6 denotes a quarter garnish provided on the outside of the upper guide rail 51, and this is formed to have an external shape continuous with the roof panel 7. This quarter garnish 6 has a step 9 on its lower edge that forms a certain gap with the quarter glass 8, and has a mounting flange 6a and an engaging claw 6b on its back surface.

To install the quarter garnish 6, fix the mounting flange 6a to the mounting panel 10 attached to the roof side panel part 3b with screws 11, and insert the engaging claw 6b into the retaining part 12 provided on the top surface of the mounting panel IO. This is done by engaging.

On the other hand, the sliding door 2 has upper, middle and lower guide rails 5゜5□, 5. Guide rollers 13□13□, 13 that engage with
° is provided, and the upper guide roller 13. is supported by an upper support arm 14 attached to the tip of the upper side of the sliding door 2.

The sliding door 2 is opened and closed by an outside handle 15 provided on the front surface of the sliding door 2 and a door lock inside handle 16 provided on the back surface.
