Description

Technical Field

[0001] This invention relates to automotive sunroofs, specifically a three-panel panoramic sliding sunroof. Background Technology

[0002] Panoramic sunroofs enhance interior lighting and ventilation and are now widely used in passenger vehicles such as SUVs and MPVs. A typical outward-sliding panoramic sunroof generally includes glass, fixed glass, a sunroof frame, a motion mechanism, a drive motor, and a sunshade assembly. The motor drives the transmission mechanism to move the glass mechanical assembly, enabling the glass to tilt for ventilation and slide outwards for opening.

[0003] In existing technologies, panoramic sunroofs with a single pane of glass can only open in the area above the front seats, and the light transmission range can only cover up to the second row of seats at most, failing to provide adequate lighting and ventilation for the third row. Sunroofs with a double-pane, segmented glass arrangement can allow the front and rear glass to open independently, but the guide rail structure is complex and costly; while sunroofs with a three-segment glass layout are difficult to slide open to a large extent in the third row.

[0004] For example, the invention patent application CN109435653A discloses a double-glass, double-opening panoramic sunroof for automobiles. It features two independently movable glass panes, one at the front and one at the back. These two panes are positioned in different guide grooves on a guide rail, allowing for separate opening and tilting actions, or simultaneous full opening of both panes, thus increasing the sunroof's opening area. However, this design employs a double-guide-groove structure, resulting in numerous components, a complex overall guide rail structure, and high manufacturing costs. Furthermore, constrained by the overall vehicle roof length, this design is difficult to adapt to large SUVs and MPVs with three rows of seats, and struggles to meet the lighting requirements of the area above the third-row seats.

[0005] For example, the invention patent applications published by CN115489283A and CN104786790A disclose a three-section roof glass layout, which extends the light transmission range of the sunroof by splicing multiple glass sections, thus adapting to long roof models; however, in this type of solution, the rear glass is mostly fixed glass or can only be tilted up individually, which cannot achieve full sliding opening of the area above the third row, so the third row passengers cannot obtain a large-opening ventilation effect.

[0006] For example, the conventional outward sliding sunroof drive and transmission structure disclosed in invention patent applications CN106080145A and CN107150579A uses a motor-chain / flexible shaft-mechanical linkage mechanism to complete the action sequence of glass closing-tilting-outward sliding. However, most of them are designed for a single piece of glass and lack a coordinated control scheme for the front and rear pieces of glass.

[0007] For large SUVs and MPVs with three rows of seats, there is still a lack of sunroof solutions on the market that can allow for large-scale light transmission above the first to third rows of seats, provide independent large-opening ventilation above the front and third rows, allow simultaneous tilting ventilation for the front and third rows, and simplify the guide rail structure to control component costs. Summary of the Invention

[0008] The purpose of this invention is to provide a three-panel panoramic sliding sunroof that fundamentally solves the above-mentioned problems. It has the advantages of full light transmission over the area above the three rows of seats in the vehicle, independent opening of the front and rear glass, simultaneous lifting and ventilation of the front and rear glass, simple guide rail structure, and controllable component costs.

[0009] To achieve the above objectives, the present invention provides the following technical solution: the key technical features of this three-pane panoramic sliding skylight are: including, A front glass assembly, which is fixed to a pair of front glass mechanical assemblies and driven by a front glass drive motor; The front glass mechanical assembly includes a first front slider and a first rear slider that are hinged to each other, a first front lifting arm that is slidably fitted on a groove of the first front slider, a first rear lifting arm that is slidably fitted on a groove of the first rear slider, and a first glass support that is hinged to both the first front lifting arm and the first rear lifting arm. A glass assembly includes a second PU edging, a second glass sheet fixed on the second PU edging, a central sealing strip, a pair of second side inserts embedded in the second PU edging, a second front insert, and a second rear insert; A rear glass assembly, which is fixed to a pair of rear glass mechanical assemblies and driven by a rear glass drive motor; The rear glass mechanical assembly includes a second front slider and a second rear slider that are hinged to each other, a second front lifting arm that is slidably fitted on a groove of the second front slider, a second rear lifting arm that is slidably fitted on a groove of the second rear slider, and a second glass support that is hinged to both the second front lifting arm and the second rear lifting arm. The front or rear glass assembly includes a first PU edging, a first glass sheet fixed on the first PU edging, a pair of first side inserts embedded in the first PU edging, a first front insert, and a first rear insert; a pair of windshield mesh blocks are also fixed at the front end of the front glass assembly. A skylight frame assembly, including a front frame, a rear frame, and a guide rail assembly fixed therebetween; Each guide rail assembly includes a vehicle body mounting section located on the outer side, a drainage area and a sunshade sliding area spaced apart on the outer and inner sides, a mechanical assembly flexible shaft hole located in the drainage area, and a windbreak mesh assembly area and a sunshade flexible shaft hole spaced apart in the sunshade sliding area. A windbreak mesh assembly includes a U-shaped fixing frame, a pair of springs fixed between the fixing frame and the frame assembly, a mesh fabric with a snap strip fixed to the top, and steel wire sewn into the bottom of the mesh fabric. The top of the mesh fabric is inserted into the fixing frame through the snap strip, and the bottom of the mesh fabric is fixed into the frame assembly through the steel wire. An inner sound insulation sealing strip, U-shaped, is located between the guide rail assembly, the front seat frame, and the first or second PU edging; A sunshade assembly, driven by a sunshade drive motor, includes a curtain roller that is limited to one side of the guide rail assembly, a curtain wound on the curtain roller, an arched beam fixed to the front end of the curtain, sunshade sliders that slide along the guide rail assembly and are fixed to both ends of the arched beam, and side strips that are fixed to both sides of the curtain and roll up with the curtain.

[0010] Furthermore, the inner soundproof sealing strip includes an integral expanding foam and a solid adhesive. The bottom of the solid adhesive is fixed to the guide rail assembly, and the expanding foam has a hollow elastic structure to elastically seal the gap between the glass assembly and the guide rail assembly.

[0011] The beneficial effects of the present invention are as follows: Through the coordinated design of a three-section longitudinal glass layout, a common rail dual independent mechanical group, zoned drive control and an integrated sunshade system, the present invention can significantly expand the lighting coverage of the panoramic sunroof while taking into account the compactness of the structure, the controllability of cost and the richness of functions, especially suitable for the use needs of three-row seat vehicles.

[0012] The sunroof employs a three-section glass structure, with the front, middle, and rear glass components sequentially joined along the vehicle's longitudinal direction. This allows the sunroof's light-transmitting area to extend fully longitudinally, completely covering the roof space directly above the front, second, and third rows of seats. This overcomes the limitation of traditional two-piece panoramic sunroofs, which only cover the first two rows. For large SUVs and MPVs equipped with three rows of seats, this ensures that every passenger enjoys a clear view above the roof, significantly enhancing the overall sense of spaciousness and comfort within the cabin, perfectly matching the panoramic lighting design requirements of high-end multi-seat passenger vehicles.

[0013] The front and rear glass components are each equipped with independent drive motors and dedicated slider-type lifting mechanisms. The two drive systems are independently controlled and do not affect each other. The front side can be driven by the front glass drive motor, which in turn drives the front glass mechanism to complete its full-stroke movement according to the logic of "first lifting, then sliding outwards," allowing the roof above the front seats to fully slide outwards and provide a large ventilation opening for front passengers. The third-row side can be independently driven by the rear glass drive motor, which in turn drives the rear glass mechanism to complete the same opening action, allowing full ventilation in the area above the third row. This independent front and rear partition design can precisely respond to the ventilation needs of passengers in different areas of the vehicle, avoiding the crude control of traditional single-pane sunroofs and significantly improving usability.

[0014] The two sets of glass movement mechanisms share the same sliding cavity within the sunroof frame guide rail, which effectively simplifies the guide rail cross-section and frame structure, reduces the number of guide rail grooves, connecting brackets and other parts, thereby reducing mold development and material costs, reducing assembly processes and improving production and assembly efficiency.

[0015] Due to spatial limitations imposed by the sliding travel within the guide rails, the front and rear glass components cannot simultaneously complete their full sliding opening. However, the lifting action of the two mechanical units only requires a short sliding distance, eliminating travel interference. Therefore, the front and rear glass components can be simultaneously driven to lift, creating ventilation gaps in both the front and rear roof areas, enabling synchronized ventilation between the front and third-row roofs. This design, within a compact structural space, fills the functional gap in existing three-row vehicle sunroofs that cannot simultaneously ventilate multiple areas, achieving an optimal balance between cost control and functional innovation.

[0016] Equipped with an independently driven electric sunshade assembly, powered by a sunshade drive motor, the sunshade's opening and closing range is infinitely adjustable. Users can flexibly adjust the sunshade's coverage area according to the angle of sunlight and the lighting preferences of different seats in the vehicle: it can be completely closed to provide a panoramic view of the entire roof, partially opened to block specific sun-exposed areas, or completely closed for full roof sun protection and heat insulation. Multiple lighting modes can be freely switched to adapt to the differentiated usage needs of passengers in different seats, such as the front driver and rear passengers, further enhancing the sunroof's user experience and adaptability to various scenarios.

[0028] The following is in conjunction with the appendix Figures 1-10 The technical solution of the present invention will be described in detail through specific embodiments. It should be understood that these embodiments are used to illustrate the present invention and not to limit the scope of the present invention. All equivalent substitutions and structural improvements made based on the concept of the present invention should fall within the protection scope of the present invention.

[0029] This embodiment relates to a three-pane panoramic sliding sunroof, mounted on the roof of a vehicle. It employs a three-segment glass layout to achieve a wide field of view and panoramic lighting, while also supporting multi-mode ventilation and sunshade adjustment. The sunroof mainly consists of a front glass assembly 1, a middle glass assembly 2, a rear glass assembly 3, a sunroof frame assembly 4, a pair of front glass mechanical assemblies 5, a pair of rear glass mechanical assemblies 6, a wind deflector assembly 7, an inner sound insulation sealing strip 8, a sunshade assembly 9, a front glass drive motor 10, a sunshade drive motor 11, and a rear glass drive motor 12. The middle glass assembly 2 is fixed in the center of the sunroof. The front glass assembly 1 and the rear glass assembly 3 can be raised for ventilation and slid outwards for opening via their respective mechanical assemblies. The sunshade, wind deflector, and sealing structure work together to ensure user comfort and overall vehicle NVH performance. Figure 1 As shown, there are four main usage states: both the front and rear windows are closed; the front window is open and the rear window is closed; the front window is closed and the rear window is open; the front window is tilted up and the rear window is tilted up.

[0030] The front glass assembly 1 is a movable front light-transmitting unit, which is rigidly mounted on a pair of symmetrically arranged front glass mechanical assemblies 5 and driven by a front glass drive motor 10. This assembly includes a first PU edging 102, a first glass sheet 101 fixed to the first PU edging 102, and a pair of first side inserts 103, a first front insert 105, and a first rear insert 104 embedded inside the first PU edging 102, as well as a drive flexible shaft (not shown in the figure). The PU edging provides protection and vibration damping for the glass edges and, in conjunction with the sealing element, achieves end-face sealing. The metal inserts serve as connecting reinforcement structures, reliably connecting the glass assembly to the glass brackets of the mechanical assemblies, ensuring the accuracy of motion transmission and structural strength. Furthermore, a pair of wind deflector blocks 106 are fixed to the left and right sides of the front end of the front glass assembly 1, used to press the wind deflector downwards when the sunroof is closed, achieving a flat roof appearance when retracted.

[0031] The central glass assembly 2 is a fixed lighting unit in the center, fixedly installed in the center of the sunroof frame assembly 4, forming the fixed viewing area of ​​the panoramic sunroof. Its main body includes a second glass pane 201 and a second PU edging 202. A pair of second side inserts 204, a second front insert 203, and a second rear insert 205 are embedded inside the edging. These inserts are bolted to the sunroof frame, ensuring long-term installation stability. The front and rear edges of the second PU edging 202 are also equipped with central sealing strips 206. When the front and rear glass are in the closed position, the central sealing strips 206 tightly fit against the end faces of the corresponding glass panes, forming a sealed partition between the glass segments, blocking the transmission path of rainwater, dust, and noise.

[0032] The rear glass assembly 3 is a movable rear light-transmitting unit, fixed to a pair of rear glass mechanical assemblies 6 and driven by the rear glass drive motor 12. Its main structure is identical to the front glass assembly 1, including a glass sheet, PU edging, a drive flexible shaft (not shown in the figure), and multiple sets of embedded connecting inserts. These inserts are securely connected to the glass bracket of the rear glass mechanical assembly 6, achieving synchronous power transmission. The front glass drive motor 10 pulls the first front slider 53 via the drive flexible shaft, sliding along the drainage area 133 of the guide rail assembly 13; the rear glass drive motor 12 pulls the second front slider 63 via the drive flexible shaft, sliding along the drainage area 133 of the guide rail assembly 13.

[0033] The sunroof frame assembly 4 is the load-bearing and integrated base of the entire sunroof. It is formed by splicing the front seat frame, the rear seat frame and the left and right guide rail assemblies 13 to form a closed frame structure, and is fixedly connected to the body and roof sheet metal through the outer mounting points.

[0034] The guide rail assembly 13 extends longitudinally along the vehicle body and adopts a multi-cavity partitioned design in its cross-section. From the inside out, it is arranged with a vehicle body mounting part 131, a drainage area 133, and a sunshade sliding area 136. Among them, the vehicle body mounting part 131 is located on the outermost side and has multiple vehicle body mounting points for the overall mounting and fixing of the sunroof. The drainage area 133 is an open water channel structure with mechanical assembly flexible shaft holes 132 inside the channel for the transmission chain / flexible shaft of the glass mechanical assembly to pass through. At the same time, it can also collect rainwater seeping in from around the glass and discharge it to the outside of the vehicle through the front and rear drainage outlets, forming a complete drainage and waterproof system. The sunshade sliding area 136 is located on the inner side of the guide rail. Inside, a wind deflector assembly area 134 and a sunshade flexible shaft hole 135 are arranged longitudinally at intervals, which are used for the fixed installation of the lower end of the wind deflector and the passage arrangement of the sunshade driving component, respectively.

[0035] The front glass mechanical group 5 and the rear glass mechanical group 6 are the core actuators that realize the composite movement of the glass "first lifting and then sliding outward". The two have the same structural principle and are symmetrically arranged in the drainage area 133 of the left and right guide rails, sharing the same sliding track.

[0036] Taking the single-sided front window mechanical assembly 5 as an example, it includes a first front slider 53, a first rear slider 54, a first front lifting arm 51, a first rear lifting arm 52, and a first glass support 55. The first front slider 53 and the first rear slider 54 are arranged longitudinally and hinged to each other, and can adapt to the trajectory changes during the movement by relative rotation; the lower end of the first front lifting arm 51 is slidably engaged in the inclined groove of the first front slider 53, and the upper end is hinged to the front of the first glass support 55; the lower end of the first rear lifting arm 52 is slidably engaged in the inclined groove of the first rear slider 54, and the upper end is hinged to the rear of the first glass support 55.

[0037] When the current glass drive motor 10 is running in the forward direction, it drives the slider to slide backward along the guide rail via a chain-like transmission mechanism. The lower end of the lifting arm moves relative to the inclined slide groove, causing the lifting arm to gradually rise and swing. This, in turn, drives the glass bracket and the front glass assembly 1 to first lift their lower ends upward. The slider continues to slide backward, and the lifting arm reaches the end of the slide groove, at which point the lifting stroke terminates. The front glass assembly 1 maintains a predetermined lifting height and slides backward and outward along the roof plane, finally stacking on top of the middle glass assembly 2, achieving full opening. When the motor runs in the reverse direction, the front glass assembly 1 moves forward and falls back in the opposite order, then the front end falls back to the closed state.

[0038] The rear glass mechanical assembly 6 includes a second front slider 63, a second rear slider 64, a second front lifting arm 61, a second rear lifting arm 62, and a second glass bracket 65. Its motion principle is completely the same as that of the front glass mechanical assembly 5, which can drive the rear glass assembly 3 to complete the lifting and forward sliding actions.

[0039] The wind deflector assembly 7 is installed at the front end of the sunroof frame to manage airflow over the roof and reduce wind noise inside the vehicle when the sunroof is open. This assembly includes a transversely arranged U-shaped fixing bracket 71, a pair of springs 72, a mesh fabric 73, a fabric retaining strip 74, and a steel wire 75.

[0040] The U-shaped fixing bracket 71 is hinged at both ends between the left and right guide rails; the mesh fabric 73 is a breathable mesh structure, with a fabric strip 74 threaded through its top, and the fabric strip 74 is inserted into the slot of the fixing bracket 71 through the interference fit to achieve positioning; the bottom of the mesh fabric 73 is threaded with a steel wire 75, and the steel wire 75 is used to fix it in the wind deflector assembly area 134 of the guide rail; a pair of springs 72 are respectively connected between the left and right ends of the fixing bracket 71 and the sunroof frame, providing an upward springing torque for the wind deflector.

[0041] When the current glass assembly 1 is closed, the wind deflector block 106 at the front of the glass presses down on the top of the mesh 73, so that the wind deflector is flat and stored under the glass; when the current glass assembly 1 is lifted or slid outward to open, the block moves backward with the glass to release the constraint, the spring 72 drives the fixing frame 71 to rotate, and the mesh 73 automatically pops up and stands upright, guiding the airflow on the roof to deflect upward, avoiding the airflow from rushing directly into the car and generating wind noise and turbulence.

[0042] The inner soundproof sealing strip 8 is U-shaped and is arranged circumferentially along the sunroof frame between the guide rail assembly 13, the front seat frame, and the PU edging of the glass assembly. It is the main sealing structure on the inner side of the sunroof. The inner soundproof sealing strip 8 includes a solid adhesive 82 at the bottom and a foam adhesive 81 at the top: the solid adhesive 82 is snapped and fixed to the inside of the profile of the guide rail assembly 13, providing a stable installation base; the foam adhesive 81 is a hollow elastic structure with excellent compression and rebound performance.

[0043] When the current glass assembly 1 or the rear glass assembly 3 is closed, the foam 81 is deformed by the PU edge compression, fully filling the gap between the glass and the guide rail, forming a multi-layer sealing barrier that is dustproof, waterproof and soundproof. At the same time, it can absorb the vibration generated by the vehicle driving, effectively improving the NVH performance of the whole vehicle.

[0044] The sunshade assembly 9 is integrated into the lower inner side of the sunroof frame and is driven by the sunshade drive motor 11. It is used to adjust the amount of light entering the vehicle and achieve sunshade and heat insulation functions. This assembly includes a curtain roller 95, a curtain 91, an arched beam 94, a pair of sunshade sliders 92 and side strips 93 on both sides, and a drive flexible shaft. The sunshade drive motor 11 pulls the sunshade sliders 92 to slide within the sunshade sliding area 136 of the guide rail assembly 13 via the drive flexible shaft (not shown in the figure) which is slidably limited within the guide rail assembly 13.

[0045] The curtain roller 95 is horizontally installed at the rear end of the skylight frame, with an internal coil spring structure to keep the curtain 91 taut at all times. The curtain 91 is wound on the curtain roller 95, and its front end is fixedly connected to the arched beam 94. The arched beam 94 is a rigid arc-shaped component used to maintain the shape accuracy and support rigidity of the front end of the curtain 91. A pair of sunshade sliders 92 are fixed to the left and right ends of the arched beam 94, and their sliding is limited within the sunshade sliding area 136 of the guide rail assembly 13. The side strips 93 are fixed to the left and right side edges of the curtain 91, and can be wound and unfolded synchronously with the curtain 91 to prevent the side of the curtain 91 from derailing, while improving the side light-blocking and sealing performance.

[0046] When the sunshade curtain drive motor 11 is running in the forward direction, it drives the sunshade curtain slider 92 to slide backward through the chain-like transmission mechanism, and the curtain 91 is gradually rolled into the roller, and the sunshade curtain is rolled up; when the motor is running in the reverse direction, the slider slides forward, and the curtain 91 is pulled out from the roller and unfolded to realize the sunshade function.

[0047] The front glass assembly 1 is mounted on the front glass mechanical assembly 5. When the front glass drive motor 10 rotates forward, it drives the front glass mechanical assembly 5 through a chain-like transmission mechanism to first complete the action of the front glass assembly 1 from closed to tilted up, and then complete its outward sliding opening action. When the front glass drive motor 10 rotates in reverse, the front glass assembly 1 completes the above actions in reverse. The rear glass assembly 3 is mounted on the rear glass mechanical assembly 6. When the rear glass drive motor 12 rotates forward, it drives the rear glass mechanical assembly 6 through a chain-like transmission mechanism to first complete the action of the rear glass assembly 3 from closed to tilted up, and then complete its outward sliding opening action. When the rear glass drive motor 12 rotates in reverse, the rear glass assembly 3 completes the above actions in reverse. The middle glass assembly 2 is mounted on the sunroof frame assembly 4 and fixed in place.

[0048] The front and rear window mechanisms 5 and 6 slide within the same guide rail of the sunroof frame assembly 4. Due to this limitation, the front and rear window mechanisms 5 and 6 cannot simultaneously unfold and slide to the bottom within the guide rail; therefore, the front and rear window assemblies 1 and 3 cannot open simultaneously. However, the front and rear window mechanisms 5 and 6 can slide and unfold a limited distance within the guide rail, thus enabling the front and rear window assemblies 1 and 3 to simultaneously tilt upwards. The front and rear window assemblies 1 and 3 are designed to tilt upwards towards the rear window assembly 3, allowing simultaneous ventilation in the roof areas of the front and third-row seats.
