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 Invention) The outer slide roof device has the basic configuration as described above. For example, in the invention of Japanese Patent Application Laid-Open No. 60-215423, the rear end of the lever 48 is bothersome. A lock link 43 having a lock pin 45 planted thereon is pivotally connected to the slide panel 3.
When the is fully closed, the lock groove is
The lock pin 45 is fitted into the lock groove 46 to which the lock body having the lock member 46 has been tacked, so that the lock pin 45 is maintained in a fully closed state. And the head clearance is reduced accordingly.

Therefore, in the present invention, by utilizing the existing guide rail groove for locking, the simplest thing is to secure sufficient head clearance, improve the closeability of the slide panel and prevent malfunctions. It is.

[Structure of device]

(Means for Solving the Problems) A pin is projected from a lever member connected to the cam member via a link, and connected to a bracket supporting the slide panel so as to be relatively movable in the front-rear direction. A notch of considerable width is provided on the upper surface, and when the pin of the shoe is behind the cam groove of the cam member and the slide panel is tilted up, the pin floats upward from the notch groove, and the pin of the shoe When the slide panel is in the fully closed state, it is inserted into the slide groove of the guide rail from the cutout groove.

(Operation) When the slide panel is fully closed, the pin of the lever member regulates the vertical movement of the upper and lower surfaces of the guide groove, thereby preventing the vertical movement of the slide panel connected to the lever member via the bracket. Ensure the fully closed state.

(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 which faces the outer surface of the vertical wall 22 of the shoe 15 and can be stored in the space 24 'between the facing walls of the guide rail 13.
Has a cam groove 26 for receiving the pin 23 of the shoe 15, and a tip 27 of the cam groove 26 is slidably disposed in the opposed groove 17 of the guide rail 13. The cam groove 26 has a substantially arc shape, and when the pin 23 moves forward and backward in the cam groove 26, the rear portion of the cam member 25 is moved up and down around the piece 27 at the tip thereof.

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. It moves along the cam groove 26 and lifts the rear part of the cam member 25 upward with the front piece 27 as the center. Pin 23 is cam groove
When the rear end of 26 is hit, 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. 6, the roller 24 rotatably supported by the support arm 25 'extending from the cam member 25 is also slightly rearward. It rises upward from the vertical guide recess 28 inclined toward and rides on the flange 19. The front wall 29 is a roller
It regulates the forward movement from the depression 28 of 24.

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 against the rear ends of the grooves 31, 32, but in the tilt-up state and fully open, abut the front 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 25 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 Groove 17
It will go inside and come into contact with the inner surface. As a result,
When the slide panel 4 is fully closed, the slide panel 4 includes the piece 27 of the cam member 25, the pin 23 of the shoe, and the pin 36 of the lever 35.
The slide panel 4 is not vibrated because it is supported by the housing at the three points. When the state is changed from FIG. 1 to FIG. 2, the shoe 15 is slightly retracted and the pin 36 is
After that, the tilt-up starts.

This state will be described with reference to FIG. 7. FIG. 7 shows the fully closed state of the slide panel 4, in which a pin 36 fixedly protruded to the lever 35 in the vehicle interior direction is provided with an inner groove 17 of the rail 13 on which the shoe 15 slides. With an appropriate gap 38 in the vertical direction. At the time of tilt-up and full opening, as described above, it floats upward from the notch 37 in FIG.

The front and rear ends of the notch 37 are bent slightly upward to make the pin 36 easily enter and exit the groove 17 of the guide rail 13 so as to have a rising shape for guidance.

[Effect of the invention]

As described above, when the slide panel 4 is fully closed,
Since the slide panel 4 is regulated by a rigid guide rail 13 fixed to the housing 5 attached to the vehicle body via the bracket 16, the lever 35, and the pin 36, unnecessary excessive vertical movement is restricted. Even if the car rolls over due to an accident, the slide panel 4 is easily squashed inward by external force, creating a space on the ceiling of the car, and the rear part of the slide panel 4 sinking into the interior of the car. I will not do it. Also, as shown in FIG. 8, even if the vehicle bounces greatly and the head or the like of the occupant pushes the slide panel 4 upward, there is no fear that the occupant easily comes off.

Furthermore, in order to ensure the fully closed state, the groove of the existing guide rail is used, and a very simple structure in which the pin protruding from the lever 35 is inserted into the groove is used. It is not a complicated structure using a large number of lock-dedicated members, so that the head clearance can be ensured and the closeability is also improved, there is no malfunction, and the practical effect is great.
