Description

Technical Field

[0001] The present invention relates to the field of skylights, in particular to a top-mounted skylight mechanical assembly. Background Art

[0002] With the development of the automotive industry, more and more cars are equipped with sunroofs. These effectively circulate air inside the vehicle, increasing fresh air intake and providing a healthy and comfortable experience for the owner. At the same time, the windows also provide a wider field of view, making the occupants feel more comfortable. Prior art already knows that multiple mechanisms exist for moving one or more glass covers of such tilting and sliding sunroofs. A common feature of these mechanisms is that they first lift the sunroof's glass cover outward and then move it backward, partially or fully opening it. Although these mechanisms have undergone continuous improvements, there is still room for structural optimization. Traditionally, the glass cover is lifted by tilting front and rear lifting arms, then supported by front and rear sliders on guide rails and moved backward to open. The lifting arms are pinned and tilted, resulting in poor stability. In strong winds, under load, or after long-term use, the support can easily deform, affecting the normal opening function and performance. Furthermore, the rearward movement of the dual sliders occupies a large amount of track space, increasing operating noise. Summary of the Invention

[0005] Drive slider , the outer side of the driving slider is provided with two front and rear slider sliding feet that are guided and placed in the guide rail slide groove of the sunroof guide rail, the driving slider is provided with a through-slot slider slide groove and a front-opening slider slide groove, and an oblique wedge block is provided on the inner side of the rear end of the driving slider;

[0006] Front bracket The front end of the front bracket is connected to the lifting arm pin, the middle part of the front bracket is limited and slidable through the through-slot slider slot through the bracket pin, and the rear part of the front bracket is provided with a guide foot slide placed in the sunroof guide rail slot;

[0007] Locking link , the front end of the locking link is provided with inner and outer link sliding feet, the outer link sliding foot is placed in the guide block locking slide groove at the rear of the inner guide block, the outer link sliding foot is correspondingly connected to or out of the slider slide groove, and a vertical pin is provided in the middle of the locking link;

[0008] Limit block The middle part of the limit block is connected to the vertical pin column and is connected to the locking link through the wire spring. A limit block boss is set at the front end of the limit block. The limit block boss is correspondingly engaged or disengaged from the guide block locking socket at the rear of the inner guide block, and the rear end of the limit block abuts or disengages the matching oblique wedge block;

[0009] intermediate connecting rod The front end of the intermediate link is pin-connected to the rear end of the locking link, and one or more link sliding feet are provided on the intermediate link, and the link sliding feet are supported on the sunroof guide rail;

[0010] Tilt link , the front end of the inclined link is pin-connected to the rear end of the intermediate link;

[0011] Arm slider The front end of the arm slider is pin-connected to the rear end of the tilt link, and the rear end of the arm slides through the arm slider;

[0012] rear bracket , the front end of the rear bracket is pin-connected to the rear end of the lifting arm slider;

[0013] The fixing seat is fixed on the sunroof guide rail, and the rear end of the rear bracket is pinned to the fixing seat.

[0014] Furthermore, the guide block side sliding grooves of the inner and outer guide blocks are respectively connected to the guide rail sliding grooves of the inner and outer inner walls of the skylight guide rail.

[0015] Furthermore, the guide block side slide groove of the outer guide block is connected to the guide rail slide groove of the outer inner wall of the skylight guide rail, and the rear part of the inner guide block is provided with a horizontal guide block slide groove connected to the side slide groove of the guide block above it, and the horizontal guide block slide groove is connected to the guide rail slide groove of the inner inner wall of the skylight guide rail.

[0016] Furthermore, the through-slot slider slide includes a front downwardly inclined end and a rear horizontal section connected to the front downwardly inclined end, and the slider slide includes a front horizontal section with a front opening and a rear upwardly inclined section connected to the horizontal section.

[0017] Furthermore, the guide block locking slide groove includes a front horizontal section and a rear vertical section.

[0018] Furthermore, three connecting rod sliding feet, namely front, middle and rear connecting rod sliding feet, are provided on the intermediate connecting rod.

[0019] Furthermore, the lower bottom edge of the rear end of the lifting arm is connected to the upper opening through slot of the lifting arm slider.

[0020] Furthermore, the maximum opening angle of the rear bracket when rotated backward is 90°.

[0021] Furthermore, the rear brackets are two symmetrical ones, the two rear brackets are pin-connected to the inner and outer sides of the arm lifting slider respectively, and the two rear brackets are pin-connected to both sides of the fixing seat respectively.

[0022] When the sunroof is opened, the driving slider is pulled backward, and the pin of the driving slider moving rearward bracket moves from the rear horizontal section to the front end in the through-slot slider slot. At the same time, the outer connecting rod sliding foot moves backward with the driving slider in the rear upward section of the slider slot, causing the locking link to move backward and push the tilting link through the middle link. The tilting link constrains the lower bottom edge of the lifting arm through the lifting arm slider, so that the rear bracket rotates around the fixed seat and lifts the rear end of the lifting arm. When the rear bracket rotates and tilts to 90 degrees, the inner connecting rod sliding foot moves from the front horizontal section of the guide block locking slot to above the rear vertical section and falls into the vertical The outer link sliding foot moves forward from the front horizontal section and disengages from the front opening, realizing the disengagement of the locking link and the rear movement of the driving slider, so that the tilting link is lifted by the lifting arm sliding foot and the rear end position of the lifting arm is stably fixed. At the same time, the oblique wedge block of the driving slider moves beyond the rear end of the limit block. The rear end of the limit block is unconstrained and under the action of the line spring, the limit block moves around the vertical section of the locking link. The straight pin rotates, and the limit block boss at the front end of the limit block rotates and snaps into the guide block locking bayonet at the rear of the inner guide block, further ensuring the locking of the locking link; the driving slider continues to pull back, and the outer link sliding foot tilts upward at the front end of the rear upward section of the slider slide groove to the front downward end, thereby driving the front end of the front bracket to lift the front end of the lifting arm. The front end of the lifting arm is lifted, and the lifting arm sliding feet through the two long pins move along the guide block side grooves of the inner and outer guide blocks and enter the guide rail grooves on both sides of the sunroof guide rail respectively, or the outer side enters the outer guide rail groove and the inner side first After entering the horizontal guide block slot, it then enters the inner guide rail slot, lifting the front end of the arm and restraining it. As the drive slider continues to pull backward, the lower edge of the rear end of the arm is guided and restrained in the open slot on the arm slider, completing the arm's movement and driving the sunroof glass backward to open. The fixed seat is fixed and does not need to move backward. The fixed seat vertically supports the arm, providing stable support and is not affected by external pressure on the sunroof. This avoids the lack of stability of traditional tilting and tilting supports, helping to reduce operating noise, save space behind the sunroof guide rail, and extend service life. The movement of the sunroof glass moving forward to close is the opposite of the above. BRIEF DESCRIPTION OF THE DRAWINGS
