Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mechanism for attaching and detaching a sunroof lid of an automobile.

BACKGROUND TECHNIQUE Conventionally, in general automobiles, a structure in which an opening is provided in the roof panel and a sunroof panel that can be closed and opened is attached is known in order to increase ventilation and a sense of openness inside and outside the vehicle interior, and it is not practical. has been made into

In these conventional examples, the sunroof panel usually has a structure that slides freely, and a structure in which an opening/closing mechanism is attached to a single sunroof panel is usually used. On the other hand, in some vehicles, a structure is used in which the sunroof panel is divided into two parts, the opening is widened above the driver, and the two lids are opened and closed independently.

Problems to be solved by the invention However, in the case of a structure in which the opening/closing mechanism is attached using a single sunroof panel as described above,
It is difficult to say that the ventilation effect inside and outside the vehicle is perfect.
In particular, since there is no opening above the driver's seat, there is a drawback that ventilation and an open feeling for the driver are insufficient. Furthermore, the structure in which the sunroof panel is divided into two has the advantage of increasing the feeling of openness, but the openness effect can be further enhanced by making at least one side of the sunroof panel removable. Conceivable. Therefore, the purpose of this invention is to provide a structure in which the sunroof panel can be opened and closed freely and can also be detached and attached at will depending on the usage situation.

Means for Solving the Problems In order to achieve the above object, the present invention is divided into two types: a tilt lid in which the sunroof panel is moved up and down using the front end as a fulcrum and the rear end is raised and lowered, and a slide lid in which the sunroof panel is slid in the longitudinal direction of the vehicle. In the automobile sunroof opening/closing device in which both of the lids are driven by a single wire, a removable structure is provided between a bracket fixed to the lower surface of the tilt lid and an elevating link pivotally supported by the bracket. The tilt lid is characterized in that the tilt lid can be removed and installed by inserting the shaft therethrough.

Operation Examples of the present invention will be described below with reference to the drawings.

FIG. 5 shows the sunroof structure and opening/closing means for an automobile to which the present invention is applied. In the figure, 1 is a tilt lid, 2 is a slide lid, and 3 is a fixed roof panel, and the sunroof panel is connected to the tilt lid 1 and the slide lid. It is composed of two lids, 2 and 2. 4 is a guide rail fixed to the vehicle body side, and a wire 5 connected to a drive motor (not shown) runs inside this guide rail 4.
is inserted movably.

A bracket 6 is fixed below the tilt lid 1, and the bracket 6 and one end of the elevating link 7 are pivotally supported. The other end of the elevating link 7 is pivotally supported by one end of a front slider 9 fitted so as to be slidable within a slider guide 8 fixed to the vehicle body. One end of a link 10 with an elongated hole is pivotally supported at the other end of the front slider 9, and the other end of the link 10 with an elongated hole extends toward the rear of the vehicle. Further, the other end of the auxiliary link 11 that coaxially supports the shaft support of the lifting link 7 and the bracket 6 is connected to the elongated hole 1.
2 is loosely fitted.

On the other hand, the slide lid 2 is supported by support plates 13 and 14 at its front and rear positions, and two links 15 and 16 are attached to the rear support plate 14 in the front and back direction. Link 1
The other ends of 5 and 16 are interlocked and connected to a slider 17 that is slidable within the guide rail 4 and driven by a drive wire through elongated holes 17a and 17b.

The basic operation of the tilt lid 1 having the above configuration is as follows. As the wire 5 moves to the right, the slotted link 10 and the front slider 9 first move to the right, and by the action of the elevating link 7 whose one end is pivotally supported by the front slider 9, the tilt lid 1 moves to the right. As shown in FIG. 6, the device is rotated counterclockwise by a predetermined angle about a fulcrum 18 at the front end which is hinged to the fixed roof, and is in a tilted up state. At this time, the auxiliary link 11 is not involved in the above rotational movement,
It simply contributes to maintaining the rigidity of the lifting link 7. On the other hand, when the tilt lid 1 rotates, the slider 17 moves rearward in conjunction with the front slider 9, but the links 15 and 16 on the slide lid 2 side run idly in the long holes 17a and 17b of the slider 17 (the (Fig. 5→Fig. 6) The slide lid 2 does not perform any operation.

Next, when the tilt-up operation accompanying the rotation of the tilt lid 1 is completed and the wire 5 further moves to the right, the links 15 and 16 attached to the slide lid 2 move in conjunction with the slider 17 and open the legs as shown in FIG. The user lowers his/her posture and takes a posture that allows him/her to enter the lower side of the roof panel 3. At this time, the connection between the end of the wire 5 and the link 10 with the elongated hole is disconnected, and the tilt lid 1 maintains a tilted-up position. Next, as the wire 5 moves, the slide lid 2 slides under the roof panel 3 as shown in FIG. 8, and the opening of the sunroof is completed. When closing the sunroof, the operation is the opposite of the opening operation described above, that is, the slide lid first slides to its original position, and then the link 15,
16 stands up and raises the slide lid 2 to the position of the roof panel 3, and then slides the front slider 9 on the child lid 1 side to the left to move the elevating link 7 from the upright state shown in FIG. 6 to the position shown in FIG. The tilt lid 1 is moved to the lying state and the tilt lid 1 is closed. During this time, the links 15 and 16 are running idle in the long holes 17a and 17b of the slider 17.

FIG. 1 is a plan view showing a state in which the bracket 6 is connected to the elevating link 7 and the auxiliary link 11;
The figure is a front view of the same, and FIG. 3 is a side view of the same. The bracket 6 is provided with an outer bracket 6a and an inner bracket 6b.
A cover member 21 having a substantially U-shaped cross section is fixed to the inside of the housing. A shaft 22 passing through this cover member 21
A spring 23 surrounding the shaft 22 is inserted together with a washer 24. As shown in FIG. 4, the shaft 22 has a stepped portion 22a in the radial direction and a chamfer 22b on the large diameter side.
It is a deformed body with a knob 25 at the tip of the small diameter side.
The fastener 26 is inserted through the knob 2.
5 and the shaft 22 are fixed. The inner bracket 6b is provided with a through hole corresponding to the shape of the chamfer 22b provided on the large diameter side of the shaft 22, and the large diameter side of the shaft 22 can be moved through the through hole. ing.

The operation of the sunroof lid attachment/detachment mechanism according to the present invention will be explained below. First, under normal conditions, as shown by the dotted line in FIG. 1, the shaft 22 passes through the cover member 21, the inner bracket 6b, and the outer bracket 6a, and the elevating link 7 and the auxiliary link 11 are pivotally supported on the large diameter side of the shaft 22. is rotatably connected to the bracket 6 side. At this time, the spring 23 applies a biasing force from the inside of the bracket inner 6b via the washer 24, thereby preventing the shaft 22 from coming off.

Next, the operation when removing the tilt lid (not shown) by separating the bracket 6, the elevating link 7, and the auxiliary link 11 will be explained. That is, Figures 1 and 3
As shown by arrow A in the figure, push the knob 25 onto the spring 2.
Pull against the urging force of 3. Then shaft 22
moves in the direction of arrow A, and the elevating link 7 and auxiliary link 11, which are pivotally supported on the large diameter side of the shaft 22, come off, and the tilt lid 1 fixed to the bracket 6 is freely removed from the surface of the roof panel. becomes possible. After pulling the knob 25, by rotating the knob 90 degrees, the large diameter side of the shaft 22 is locked inside the bracket inner 6b, and the bracket 6, the elevating link 7, and the auxiliary link 11 are locked. This facilitates the removal and removal operation.

Effects of the Invention As explained in detail above, according to the present invention, a removable shaft is inserted between a bracket fixed to the lower surface of the tilt lid and an elevating link pivotally supported by the bracket, thereby making it possible to remove the tilt lid. It also has the unique effect of making installation work extremely easy. Therefore, since at least one of the two sunroof panels can be freely attached and detached, it has the advantage of increasing the ventilation effect and sense of openness for the occupants.
It is particularly effective when applied to passenger cars or one-box cars.
