Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door switch mechanism for detecting the open/closed state of a sliding door in a sliding door vehicle.

As shown in FIG. 1, the present applicant has previously proposed a center pillar-less sliding door vehicle that employs a hinge type front door and a sliding type rear door.

Since this type of sliding door car does not have a center pillar, there are significant restrictions on where to install the door switch that detects the opening/closing status of the sliding door, and it is difficult to install the door switch so that it can operate easily and stably. difficult.

Therefore, it is conceivable to provide a door switch S on the rear end surface of the vehicle body opening as shown in FIG. 1, and to operate the door switch S by applying a part of the rear end surface of the sliding door 1 to the door switch S when the sliding door 1 is fully closed. .

However, although the concept of a door switch is to have a plane perpendicular to the push button as its actuating part and apply operating force from the outside, the above structure does not allow the sliding door to slide due to the relationship with the trajectory of the sliding door 1. Place the rear end of door 1 on the door switch S.
It is extremely difficult to hit the target at right angles to the target. As a result, excessive force is applied to the push button of the door switch S, resulting in malfunction and shortening the lifespan of the filter, as well as a lack of operational reliability of the door switch.

This invention was made in view of the above-mentioned problems, and includes a guide rail that proposes and supports a sliding door and is arranged on the outer side of the roof side rail, and the end portion of the guide rail on the door closing direction is connected to the vehicle. In a sliding door vehicle with a structure bent toward the interior, a mounting surface is formed on a part of the roof side rail that is perpendicular to the axis of the end of the guide rail, and this mounting surface is used to open and close the sliding door. While installing a door switch operated by
On the inner side of the sliding door, a contact surface is formed that is parallel to the mounting surface and that contacts the operating part of the door switch at right angles to activate it when the sliding door is closed.This particularly improves the durability of the door switch. The aim is to improve the performance and operational reliability.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

2 to 4 show one embodiment of the present invention, and in particular, FIG. 2 shows an enlarged view of section A in FIG. 1. In the figure, 1 is a sliding door, 2 is a roof side rail, and the roof side rail 2
An upper guide rail 3 having a substantially C-shaped cross section and an open lower surface is disposed on the outer side of the rail. As shown in FIGS. 2 and 3, the upper guide rail 3 has an end portion 3a on the front end side.
The terminal portion 3a is bent toward the inside of the vehicle compared to the other straight general portions, and the terminal portion 3a is located further inside the vehicle than the traveling trajectory of the sliding door 1, that is, the axis of the traveling shaft of the sliding door 1 (the axis in the longitudinal direction of the vehicle body). are doing.

A roller arm 5 having a guide roller 4 is rotatably attached to the inner side of the sliding door 1 via a roller bracket 6. By engaging the guide roller 4 with the upper guide rail 3, The entire sliding door 1 is guided and supported by an upper guide rail 3.

As is well known, in addition to the upper guide rail 3, the sliding door 1 is guided and supported by a center guide rail at the waist portion of the vehicle body and a lower guide rail at the bottom of the vehicle body (not shown).

A substantially triangular bracket 7 is disposed in a portion of the roof side rail 2 corresponding to the end portion 3a to define a part thereof, and the end portion 3a of the upper guide rail 3 is connected to an opening. 2a faces into the bracket 7, and this end portion 3a is fixed to one inclined wall portion 7a of the bracket 7 via a rail bracket 8. On the other hand, the other inclined wall portion 7b of the bracket 7 is formed to be approximately perpendicular to the axis of the end portion 3a of the upper guide rail 3, and the door switch 9 is attached to the screw 10 using this inclined wall portion 7b as a switch mounting surface. It is installed.

The end surface 6a of the roller bracket 6 is formed in advance so as to be substantially parallel to the inclined wall portion 7b, and when the sliding door 1 is fully closed, the end surface 6a of the roller bracket 6 is used as a contact surface and is pressed by the operating section of the door switch 9. The door switch 9 is operated to switch (on-off operation) by bringing it into contact with a certain push button 9a.

In addition, in the figure, 11 is a drip seal fitted to the overlapping part of the roof panel 12 and drip channel 13, 14 is an outer of the roof side rail 2,
The door weather strip is fitted into the overlapping part of the inners, and as a result, the door switch 9 is connected to the drip seal 11 and the door weather strip 1.
This means that it is provided in the middle of the so-called double seal structure between 4 and 4.

Therefore, according to the above configuration, when the sliding door 1 is pulled forward to perform a closing operation, the end surface 6 of the roller bracket 6, which serves as the abutting surface against the push button 9a of the door switch 9, is in the fully closed state of the sliding door 1.
Since point a hits at a right angle, the switching operation can be performed ideally and without difficulty.

As described above, according to the present invention, in a sliding door vehicle in which the end portion of the guide rail on the side in the door closing direction is bent toward the interior of the vehicle, the roof side rail side has a surface perpendicular to the axis of the end portion. A mounting surface is formed, and a door switch is mounted on this mounting surface, while a contact surface is formed on the sliding door that is parallel to the mounting surface and that contacts the operating part of the door switch at right angles to operate the door switch when the door is closed. Therefore, when the door is closed, the contact surface can ideally contact the door switch at right angles to operate the door switch. As a result, the door switch will not malfunction, and the durability and operational reliability of the door switch itself will be improved, making it possible to improve the durability and operational reliability of the door switch itself, making it ideal for cases where the mounting location of the door switch is severely restricted, such as in center pillar-less sliding door vehicles. Especially advantageous.

In addition, since the door switch is located inside the roof side rail at the upper part of the door opening, the door switch is not exposed or protrudes from the door opening, especially toward the passenger space, which improves the appearance of the door, and at the same time improves the appearance of the door. This has the effect of preventing contact when getting on and off the vehicle and damage to the door switch due to this contact.
