Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for an automobile door switch.

For example, in a front door of an automobile having a hinge at the front end, a door switch for detecting opening/closing of the door has conventionally been generally disposed at the lower part of a center pillar against which the opening/closing end, that is, the rear end of the door comes into contact. In some cases, the switch is installed on the front pillar to which the door hinge is attached, and in this case, the plunger of the switch is installed so as to move forward and backward in the longitudinal direction of the vehicle, and is pressed by the front end surface of the door.

In recent years, a door structure has been proposed in which the rear door is a sliding door, thereby eliminating the center pillar between the hinged front door and securing an extremely large opening area on the side of the vehicle. In such a door structure, the door switch of the front door cannot of course be placed on the center pillar, so it cannot be compared with the structure where it is placed on the front pillar as described above.

However, in the configuration in which the door switch is provided on the front pillar at the end of the door hinge as described above, the stroke of the door switch in response to changes in the door angle becomes extremely small, so when detecting the movement of the rear end of the door using the center pillar, Detection accuracy is lower than that. In other words, the installation error of the door switch, the variation in the operating point of the switch itself,
Furthermore, door installation errors and the like greatly affect the detection accuracy of the door switch. Therefore,
In particular, when this door switch is used to detect a so-called half-latched state, extremely high accuracy is required for the installation of the door switch and the accuracy of the operating point of the switch itself, and the adjustment is difficult. be.

This invention was made in view of the above-mentioned points, and its purpose is to obtain a sufficiently large stroke of the door switch in response to changes in the angle of the door, and to provide a pillar on the opening/closing end side of the door. To provide a mounting structure for a door switch that can be applied to a door structure that does not have a door switch.

That is, the mounting structure for an automobile door switch according to the present invention includes interposing a double weather strip (upper and lower) between the side sill and the lower edge of a door that can be opened and closed and has a hinge at one end. The present invention is characterized in that a door switch that comes into contact with the door is disposed at a position near the opening/closing end and sandwiched between the weather strips.

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

Figures 1 and 2 show an embodiment in which the present invention is applied to a front door 1 of an automobile having a structure in which the front door 1 is a hinge type door, the rear door 2 is a sliding type door, and the center pillar between the two is eliminated. The front door 1 has hinges 3, 3 at its front end, and locking devices 4, 4 at the top and bottom of its rear end, which is the opening/closing end. Also, between the lower edge of the front door 1 and the side sill 5, there is a weather strip 6 fixed to the upper edge of the side sill 5.
and a weather strip 7 fixed to the lower end of the front door 1 form a double upper and lower seal, and both the weather strips 6 and 7 are fixed to the rear edge of the front door 1. The weather strip 8 is connected to the weather strip 8. The door switch 9 is fixed on the side sill 5 near the rear end of the front door 1 at a position where it is sandwiched between the upper and lower weather strips 6 and 7, and as shown in FIG. The lower end portion of 1a is adapted to abut against the plunger 9a.

Now, according to the above configuration, the door switch 9 directly detects the movement of the rear end of the front door 1 and has a larger stroke in response to a change in the door angle, so the door switch 9 can detect the movement more easily than when the door switch is installed on the front pillar. Accuracy is increased, and the full-latched state and half-latched state of the locking devices 4, 4 can be clearly detected, and the effects of installation errors of the door switch 9 and variations in the operating point of the switch 9 itself are reduced, making accuracy control easier. . In addition, when the door switch 9 is provided on the side sill 5 in this way, the influence of rainwater and splashed muddy water becomes a problem, but in the above configuration, the upper and lower weather strips 6 and 7 block it from the outside. Since the door switch 9 is disposed at the location where the door switch 9 is located, there is no risk of rainwater or muddy water entering the switch 9.
Although a door switch normally has a rubber boot fitted over its plunger for sealing, it is also possible to omit this rubber boot.

It should be noted that the present invention is not limited to the door structure of the above embodiment, but can be applied to hinged doors in general.

As is clear from the above explanation, according to the automobile door switch mounting structure according to the present invention, it is possible to obtain a sufficiently large stroke of the door switch in response to changes in the door angle, and it is possible to accurately detect the door ajar. At the same time, problems such as rainwater or muddy water entering the switch and rusting of the switch mounting part will not occur.
