Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to an improvement of a sunroof, more specifically, an outer slide type sunroof.

(Prior Art) A mechanism for providing an opening in a roof panel of an automobile and opening and closing the opening by a manual operation or an electric operation of a slide panel, that is, a sunroof is widely used. The cause of the spread of the sunroof is that the vehicle equipped with the sunroof gives the occupant a great feeling of openness and provides excellent ventilation to the room.

The mechanism for opening and closing the roof panel opening by the slide panel will be briefly described below. A rectangular housing having an opening in the center around the opening of the roof panel of the vehicle is fixed. A guide rail extending in the front-rear direction is fixed to the left and right sides of the housing, and an electric motor serving as a driving source is attached to a rear portion of the guide rail. Make it possible. A pair of shoes located in each guide rail is housed, these shoes are connected to a slide panel via a link having a cam groove, and the shoes are connected to an electric motor via a drive cable.

When the occupant switches on in the opening direction, the electric motor operates, pulls the shoe backward, and raises the slide panel rearward with its leading end as the center to create a tilt-up state. Keep the tilt-up state for a while while maintaining the switch-on state. The occupant who desires the tilt-up state switches off at this time. If the occupant who wants to retract the slide panel and open the roof panel opening remains on, the electric motor operates again, the tilt-up slide panel is retracted, the roof panel opening is opened, and the passenger compartment is opened. To the outside. To close the opening, the switch is turned on in the closing direction, and the slide panel is moved in the opposite direction to that described above.

A weather strip is mounted around the slide panel, and when the slide panel is in a closed state, the space between the slide panel and the opening edge of the roof panel is sealed with the weather strip to prevent rainwater or the like from entering the room. Even if rainwater passes through the weather strip, it is drained to the outside by the rain gutter of the housing. When the slide panel is in the tilted state, the rainwater adhering to the outer surface of the slide panel is drained outside through the rain gutter.

(Problem to be solved by the present invention) The outer slide roof device has the basic configuration as described above. For example, in Japanese Utility Model Laid-Open No. 63-119115,
Since the bracket (10) is at the position of the pin (12) and is not restricted from moving outward (leftward in FIG. 6), the position is not determined until the bracket (10) is mounted on the slide panel (6F). There is a problem that the reliability of the operation cannot be confirmed by moving the cable as a rail assembly, and the mounting accuracy of the bracket (10) to the slide panel (6F) is accordingly reduced.

Therefore, in the present invention, a guide rail assembly including a bracket can be preliminarily operated by an operation cable, and the technical problem is to improve the mounting accuracy on a slide panel.

[Structure of device]

(Means for Solving the Problems) At the position of the shoe pin outside the vehicle, a standing wall is formed integrally extending from the shoe and formed upright, and is fixed to the cam member at all times. The purpose is to restrict the movement of the outside of the vehicle.

(Operation) When the shoe moves back and forth along the guide rail by the cable, the upright wall always restricts the movement of the bracket to the outside of the vehicle, and the operation as a guide rail assembly including the bracket can be confirmed.

(Embodiment) An embodiment of the present invention will be described with reference to the accompanying drawings. An opening 3 is provided in a roof panel 2 of an automobile 1. The slide panel 4 is mounted on the opening 3. The slide panel 4 is in a closed state in which the opening 3 is closed as shown in FIG.
A tilt-up state in which the rear portion is lifted upward as shown in the figure and a fully open state (or a partially open state) shown in FIG. 3 can be selected by a mechanism described later.

A mechanism shown in FIG. 4 is fixed inside the roof panel 2 and around the opening 3. This mechanism has a housing 5 made of synthetic resin which is substantially rectangular when viewed from a plane. The housing 5 has an opening 6 at the center corresponding to the opening 3 of the roof panel 2, and its outer peripheral edge is formed into a box shape by an upwardly rising wall 7. The periphery of the opening 6 is also a rising wall, and a rain gutter 8 is formed around the housing 5. Rain water collected by the rain gutter 8 is drained out of the vehicle through a drain port 9. The electric motor 10 is fixed to the rear part of the housing 5. The output of the electric motor 10 is converted into pushing and pulling motions of the drive cables 11 and 12 via a speed reducer.

Guide rails 13 and 14 are fixed to the left and right sides of the housing 5, and shoes 15 are arranged on these guide rails 13 and 14 so as to be slidable in the front-rear direction. Each shoe 15 in both guide rails 13, 14
Is connected to one of the drive cables 11 and 12. Each shoe is connected to the slide panel 4 via a bracket 16 and a cam member 25 described later.

Please refer to FIG. The guide rail 13 has an inward facing groove 17 formed on the facing wall surface, and a substantially circular hole 18 through which the drive cable 11 passes on the inner wall surface. On the upper part of the guide rail 13, flanges 19 and 20 projecting sideways are formed. The shoe 15 has a piece 21 slidably housed in the groove 17 and a vertical wall 22 on which a pin 23 is attached.
To support. The drive cable 11 is fixed inside the shoe 15. The pushing and pulling movement of the drive cable 11 by the operation of the electric motor 10 causes the shoe 15 to move forward and backward along the guide rail 13.

A cam member 25 that faces the outer side surface of the vertical wall 22 of the shoe 15 and can be stored in the space 24 between the facing wall surfaces of the guide rail 13 includes:
It has a cam groove 26 for receiving the pin 23 of the shoe 15, and a piece 27 at the tip thereof is slidably disposed in the opposed groove 17 of the shoe 15.
The cam groove 26 has a substantially arc shape, and when the pin 23 moves back and forth in the cam groove 26, the rear portion of the cam member 25 is
Move up and down around 27.

A bracket 16 is fixed to a side surface of the cam member 25, and the front and rear of the slide panel 4 are fastened to the bracket 16. Therefore, the vertical movement of the cam member 25 around the piece 27 creates a fully closed and tilted state of the slide panel 4. In order to obtain the tilt-up state shown in FIG. 2 from the closed state of the slide panel 4, when the electric motor 10 is operated and the drive cable 11 is pulled, the shoe 15 retreats along the guide rail 13 and the pin 23 is moved. The cam member 25 is moved along the cam groove 26 so that the rear portion of the cam member 25 is
And lift it up. When the pin 23 contacts the rear end of the cam groove 26, the tilt-up operation is completed. At this time, in conjunction with the lift-up of the cam member 25 integrally connected to the bracket 16 shown in FIG.
Roller rotatably supported by a support arm 16 'extending from the roller
24 also has a slightly inclined guide recess in the vertical direction 28
From above and ride on the flange 19. In addition, the front wall 29 regulates the forward movement of the roller 24 from the depression 28.

Drive cable 11
Then, since the pin 23 is in contact with the rear end of the cam groove 26, the shoe 15 pulls the cam member 25 rearward, and the slide panel 4 opens the opening 3 of the roof panel 2. The backward movement of the slide panel 4 is caused by the opposing grooves 17 of the piece 27.
, The pin 23 contacts the cam groove 26, and the roller 24 is guided by rolling on the flange 19, so that the slide panel 4 does not rattle.

One end of the link 30 is pivotally connected to the pin 23 of the shoe 15. The front end of a lever 35 having a pair of grooves 31 and 32 through which a pin 33 at the rear end of the cam member 25 passes and into which groove a pin 34 at the rear end of the bracket 16 passes. It pivots at the rear end of link 30. When the slide panel 4 fully closes the opening 3, the pins 33, 34 abut the front ends of the grooves 31, 32, but in the tilt-up state and fully open, the pins 33, 34 abut the rear ends of the grooves 31, 32. A pin 36 is erected on the rear of the lever 35. This pin 36
The longitudinal position of the cam groove 26 is determined by the longitudinal length of the cam groove 26.However, the cam groove 26 is horizontal from the fully closed state to the start of the tilt-up state. fall back. In the tilt-up start state shown in FIG. 2, the pin 36 is inserted into the notch 37 of the flange 20 inside the guide rail 13.
, And thereafter floats above the notch 37 via the link 30 as the cam member 26 rises in response to the tilt-up operation. Conversely, the cam member is used to change from the tilt-up state of FIG. 2 to the fully closed state of FIG.
When returning to the tilt-up start state with the descent of 25, the pin
36 returns to the notch 37, and the slide panel 4 is in the fully closed state in FIG. 1, but when the shoe 15 further advances, the pin 23 moves to the front end along the horizontal portion in the cam groove 26, and the pin 36 It will also go into the flange 20 and come into contact with the inner surface. As a result, when the slide panel 4 is fully closed,
Is the piece 27 of the cam member 25, the pin 23 of the shoe, the lever 35
Are supported on the housing side by three points of the pin 36, so that the slide panel 4 does not vibrate. When the state shown in FIG. 1 is changed to the state shown in FIG. 2, the shoe 15 is slightly retracted so that the pin 36 faces the notch 37, and then the tilt-up starts.

FIG. 7 shows an enlarged cross section of a portion where the pin 23 implanted in the shoe 15 is fitted via the slider 50 in the cam groove 26 of the cam member 25 in the fully closed state. But shoe 15
Piece 21 is slidably fitted in the groove 17 of the guide rail 13, and the piece closer to the outside of the vehicle (right side in the figure)
An upright wall 51 is formed to extend from the outer wall surface of the cam member 25.
25 ', that is, the movement of the cam member 25 and the bracket 16 fixed thereto to the right (outside) is restricted.

The upright wall 51 moves the shoe 15 and the cam member 25 relative to each other in the front-rear direction substantially by the length of the cam groove 26 from the fully closed state to the tilted up state. 25 ', so that the upright wall 51 and the outer wall 25' are kept in contact with each other even in the tilt-up state other than in this figure and in the fully opened state with the shoe 15 and the cam member 25 retracted integrally. Is done.

(Effect of the Invention) Since the cam member, ie, the bracket, is always restricted to the outside of the vehicle by the upright wall provided on the shoe, the reliability of the operation as the guide rail assembly including the bracket is ensured before assembly to the slide roof. It can be checked by operating the cable, and therefore the position of the bracket with respect to the guide rail is also guaranteed, so that the mounting accuracy on the slide panel is improved, and the standing wall is also resistant to external force to improve the outside of the slide panel (bracket). It works effectively as a blocking means, improves strength, and has a great practical effect.
