Description

Technical Field

[0001] This invention relates to the field of automotive sunroof technology, specifically to an openable roof system. Background Technology

[0002] Most sedans and SUVs currently available are equipped with sunroofs. Sunroofs effectively improve air circulation inside the vehicle, increasing the intake of fresh air and providing a healthier and more comfortable experience for the occupants. They also offer a wider field of vision, enhancing the comfort of those inside. Most sunroofs typically consist of a fixed glass panel and a movable, sliding glass panel. The sliding glass panel has tilting mechanisms connected to both sides, and guide rails on both sides of the roof cooperate with these mechanisms to tilt and move the panel, thus opening or closing the sunroof. However, this type of sunroof only allows for the movement of one glass panel, limiting the opening range and the degree of openness.

[0003] Especially for the new energy vehicles currently being promoted on the market, most of their models use large glass panels on the roof to obtain a wider field of vision, and the aforementioned sunroof mechanism cannot meet the needs of such models.

[0004] An existing automotive roof-mounted panoramic sunroof, with publication number CN109435653A, discloses a front glass panel and a rear glass panel. It has a flexible shaft drive structure and a tilting structure on both sides of the guide rail, so that the front glass panel opens after tilting and partially opens onto the rear glass panel, thereby obtaining the opening angle of the front glass panel. However, in order to achieve the above effect, the front glass panel occupies most of the roof area and has a large movement stroke. Especially after long-term use, the front glass panel with a large movement stroke will inevitably vibrate during the movement.

[0005] A prior art double-glass double-opening panoramic sunroof, with publication number CN107471979A, discloses a lifting structure on the front and rear glass panels. However, its double-opening structure can only achieve the lifting of the front and rear glass panels together. When fully opened, it is consistent with the sunroof in the prior art, with the front glass panel partially pressed against the rear glass panel.

[0006] In summary, the front and rear glass panels of the aforementioned prior art still have significant angle limitations when open, which restricts the degree of sunroof opening. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an openable roof system that allows the sunroof to be fully opened.

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an openable roof system, comprising a roof with an opening, guide rails disposed on both sides of the opening, a front roof at the front of the opening, and a rear roof at the rear of the opening, the roof system having a closed state, a raised state, and an open state.

[0009] The roof system also includes:

[0010] A front glass assembly, with front motion mechanisms connected to both sides of the front glass assembly, and front actuation components connected to the front motion mechanisms for providing drive, the front actuation components driving the front glass assembly to reach a tilted state within the front motion mechanisms;

[0011] A rear glass assembly, wherein a rear motion mechanism is connected to both sides of the rear glass assembly, and a rear actuation component is connected to the rear motion mechanism for providing drive, and the rear actuation component drives the rear glass assembly to reach a tilted state within the rear motion mechanism;

[0012] In the closed state, the front glass assembly and the rear glass assembly are tightly fitted together by relative compression.

[0013] In the tilted state, the front glass assembly tilts relative to the front roof, and the rear glass assembly tilts relative to the rear roof. The front actuator and the rear actuator continue to drive the front glass assembly and the rear glass assembly to move away from each other until they reach the open state. In the open state, the front glass assembly is supported above the front roof by the front motion mechanism, and the rear glass assembly is supported above the rear roof by the rear motion mechanism.

[0014] Furthermore, the front actuation component includes a first flexible shaft connected to the front motion mechanism, and the rear actuation component includes a second flexible shaft connected to the rear motion mechanism. The guide rail has a first channel and a second channel distributed vertically. The first flexible shaft travels through the first channel, and the second flexible shaft travels through the second channel.

[0015] Furthermore, both the front and rear motion mechanisms include a slider assembly and a rocker arm assembly that can travel within the guide rail. The rocker arm assembly has a lower support leg assembly connected within the slider assembly and an upper support leg assembly connected to the front and rear ends of the glass assembly. The slider assembly has a pre-set slide rail assembly for the lower support leg assembly to lift upward within it. The actuating component drives the slider assembly to travel along the slide rail assembly, so that the rocker arm assembly is lifted within the slide rail assembly and reaches a tilted state. After the lower support leg assembly travels to the end of the slide rail, the rocker arm assembly and the slider assembly are synchronously driven and continue to travel to the open state.

[0016] Furthermore, the slider assembly includes a first front slider and a second front slider corresponding to the front glass assembly, the rocker arm assembly includes a first front rocker arm that can be tilted up in the first front slider, and a second front rocker arm that can be tilted up in the second front slider, and the guide rail is also provided with a front guide seat for guiding and maintaining the first front rocker arm in a tilted state.

[0017] The front motion mechanism also includes a transmission component, one end of which is integrally formed with the first front slider, and the other end of which is in transmission cooperation with the second front slider. The drive end of the front actuation component is connected to the middle of the transmission component.

[0018] Furthermore, the first front rocker arm has a first upper front support connected to the front end of the front windshield assembly, and a first lower front support and a second lower front support connected within the first front slider. The first front slider is provided with a first front lifting slide and a straight slide. The first lower front support is inserted into the first front lifting slide and tilts up at its top. The second lower front support is inserted into the straight slide.

[0019] Furthermore, the second front rocker arm has a second upper front support connected to the rear end of the front windshield assembly, and a third lower front support and a fourth lower front support connected within the second front slider. The second front slider is provided with a second front lifting slide and a first guide slide that are connected. The first guide slide has a generally downward guiding tendency, and the second front lifting slide has a generally upward guiding tendency. The third lower front support is placed at the starting point of the first guide slide, and the fourth lower front support is placed at the starting point of the second front lifting slide.

[0020] Furthermore, the slider assembly includes a rear guide seat and a first rear slider corresponding to the rear glass assembly. The rear actuator is connected to the first rear slider. The rocker arm assembly includes a first rear rocker arm that can be tilted within the rear guide seat and a second rear rocker arm that can be tilted within the first rear slider. The rear guide seat is placed within the guide rail, and the rear guide seat guides and maintains the first rear rocker arm in a tilted state.

[0021] Furthermore, the first rear rocker arm has a first upper rear support connected to the front end of the rear window assembly, a first lower rear support connected to the rear guide seat, and a second lower rear support set to move along the guide rail. The rear guide seat is provided with a first rear lifting slide, and the first lower rear support is located in the first rear lifting slide. The first rear lifting slide connects to the guide rail and limits the first lower rear support to slide on the upper part of the guide rail. The second lower rear support is hinged to a slide block, and the slide block has at least a plurality of sliding feet inserted into both sides of the guide rail.

[0022] Furthermore, the second rear rocker arm has a second upper rear support leg connected to the rear end of the rear window assembly, and a third lower rear support leg and a fourth lower rear support leg connected within the first rear slider. The first rear slider is provided with a second rear lifting slide and a second guide slide that are connected to each other. The second guide slide has a generally downward guiding tendency, and the second rear lifting slide has a generally upward guiding tendency. The third lower rear support leg is placed at the starting point of the second guide slide, and the fourth lower rear support leg is placed at the starting point of the second rear lifting slide.

[0023] Furthermore, the front glass assembly includes: a front glass panel, and a front PU frame forming around the front glass panel; the rear glass assembly includes: a rear glass panel, and a rear PU frame forming around the rear glass panel.

[0024] The rear PU frame is provided with a sealing seat facing the front glass assembly. The sealing seat is provided with a sealing bubble strip near its vertical boundary. The sealing seat is provided with a water guide groove at its horizontal boundary. The end of the front PU frame is provided with an inclined pressing part for pressing and engaging with the sealing bubble strip.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. By setting the front glass assembly and the rear glass assembly on the roof respectively, the proportion of the sunroof on the roof is increased. At the same time, the front movement mechanism and the rear movement mechanism are set at the bottom of the front glass assembly and the rear glass assembly respectively, so as to drive the front glass assembly to tilt forward and move forward, and drive the rear glass assembly to tilt backward and move forward, so as to realize the relative full opening of the two sunroofs, thereby obtaining a larger open area to a great extent. Moreover, the front glass assembly and the rear glass assembly are set in opposite directions, so that the two movement mechanisms can be set independently in separate sections, thereby eliminating the mutual influence between the two movement mechanisms and facilitating the spatial arrangement.

[0026] 2. Both the front and rear actuators are located at the bottom of the rear roof, facilitating modular assembly of the actuators. The front actuator is connected to the first flexible shaft, and the rear actuator is connected to the second flexible shaft. The first and second flexible shafts can be installed relatively independently in the first and second channels. The guide rails allow the legs of the front and rear motion mechanisms to slide within them, while also providing travel channels for the first and second flexible shafts, resulting in a more rational spatial arrangement.

[0027] 3. The rear glass assembly is divided into sections, so that when the rear glass assembly is open, it can be partially or fully opened above the rear roof, thereby further improving the openness of the roof opening. Attached Figure Description

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0061] like Figure 1-14 As shown, an openable roof system includes a roof frame forming part of the roof 1, an opening formed on the roof frame, and guide rails 2 on both sides of the opening. A front roof 1.11 is provided at the front of the opening, and a rear roof 1.21 is provided at the rear of the opening. Both the front roof 1.11 and the rear roof 1.21 are fixed to the roof frame. The roof system has a closed state, a raised state, and an open state.

[0062] The roof system 1 also includes:

[0063] The front glass assembly 3 has front motion mechanisms connected to both sides. The front motion mechanisms travel within the guide rail 2. The front motion mechanisms are connected to a front actuation component 5 for providing drive. The front actuation component 5 drives the front glass assembly 3 to reach a tilted state within the front motion mechanism.

[0064] The rear glass assembly 4 has a rear motion mechanism connected to both sides. The rear motion mechanism travels within the guide rail 2. The rear motion mechanism is connected to a rear actuation component 6 for providing drive. The rear actuation component 6 drives the rear glass assembly 4 to reach a tilted state within the rear motion mechanism.

[0065] A sealing assembly is provided at least on the front and rear sides of the front glass assembly 3 and the front and rear sides of the rear glass assembly 4, so that in the closed state, the front glass assembly 3 and the rear glass assembly 4 are pressed together in a tight fit, the front glass assembly 3 can fit tightly with the end of the front roof 1.11, and the rear glass assembly 4 can fit tightly with the end of the rear roof 1.21.

[0066] In the tilted state, the front actuator 5 and the rear actuator 6 continue to drive the front glass assembly 3 and the rear glass assembly 4 to move away from each other to the open state. In the open state, the front glass assembly 3 is supported above the front roof 1.11 by the front motion mechanism, and the rear glass assembly 4 is supported above the rear roof 1.21 by the rear motion mechanism.

[0067] like Figure 4 , Figure 8 and Figure 12As shown, in this embodiment, by setting a front glass assembly 3 and a rear glass assembly 4 on the roof 1 respectively, compared with the sunroof method of setting a fixed glass and a moving glass on the roof 1, the sunroof method of the present invention increases the proportion occupied by the moving sunroof on the roof 1. The front glass assembly 3 and the rear glass assembly 4 are set in opposite directions, thereby further improving the opening degree.

[0068] As a further explanation of the sealing assembly, the front glass assembly 3 includes: a front glass panel, a front PU frame 8 forming the periphery of the front glass panel, and front drive frames hinged to the front motion mechanism on both sides of the front PU frame 8. The front drive frames and the outer boundary of the front PU frame 8 form a retaining edge surrounding the periphery of the front motion mechanism.

[0069] The rear glass assembly 4 includes: a rear glass panel, a rear PU frame 7 forming the periphery of the rear glass panel, and rear transmission frames hinged to the rear motion mechanism on both sides of the rear PU frame 7. The rear transmission frames and the outer boundary of the rear PU frame 7 form a retaining edge surrounding the rear motion mechanism.

[0070] The rear PU frame 7 is provided with an L-shaped sealing seat 7.1 facing the front glass assembly 3. The sealing seat 7.1 is provided with a sealing bubble 7.2 near its vertical boundary. The sealing seat 7.1 is provided with a water guide groove at its horizontal boundary. The end of the front PU frame 8 is provided with an inclined pressing part 8.1 for pressing and engaging with the sealing bubble 7.2.

[0071] As those skilled in the art will recognize, the aforementioned structure can also be used between the front glass assembly 3 and the front roof 1.11, and between the rear glass assembly 4 and the rear roof 1.21.

[0072] like Figure 4 As shown, as a further embodiment of the operation of the front glass assembly 3 and the rear glass assembly 4, both the front and rear motion mechanisms include a slider assembly and a rocker arm assembly that can travel within the guide rail 2. The slider assembly is provided with a sliding foot assembly, and the guide rail 2 is provided with a motion channel assembly for the sliding foot assembly to slide within it. The rocker arm assembly has a lower support foot assembly connected within the slider assembly and an upper support foot assembly connected to the front and rear ends of the glass assembly. The slider assembly is pre-set with a slide rail assembly for the lower support foot assembly to lift upward within it. The actuating component drives the slider assembly to travel along the slide rail assembly, so that the rocker arm assembly is lifted within the slide rail assembly and reaches a tilted state. After the lower support foot assembly travels to the end of the slide rail, the rocker arm assembly and the slider assembly are synchronously driven and continue to travel to the open state.

[0073] like Figure 13 As shown, in one embodiment of the front actuator 5 and the rear actuator 6, the roof frame 1 has a bracket at the bottom of the rear roof 1.21 for mounting the front actuator 5 and the rear actuator 6, wherein:

[0074] The front actuation assembly 5 includes a first flexible shaft 5.1 connected to the front motion mechanism and a first actuator 5.2 for driving the first flexible shaft 5.1 forward. The rear actuation assembly 6 includes a second flexible shaft 6.1 connected to the rear motion mechanism and a second actuator 6.2 for driving the second flexible shaft 6.1 forward. The first actuator 5.2 and the second actuator 6.2 are both arranged at the bottom of the bracket. Each flexible shaft is connected to a set of motion mechanisms. The front and rear actuation assemblies 6 can be inherited on the bracket, which facilitates the assembly of the front and rear actuation assemblies 6.

[0075] like Figure 14 As shown, additionally, two guide rails 2 have a first channel 2.3 and a second channel 2.4 distributed vertically. The first channel 2.3 and the second channel 2.4 are formed by milling, and one side of the first channel 2.3 and the second channel 2.4 has an opening to facilitate the assembly of the flexible shaft. In addition, the opening side of the first channel 2.3 and the second channel 2.4 is provided with a beveled boundary to relatively reduce the cross-sectional area of ​​the channel, increase the compactness of the flexible shaft in the channel, and avoid unnecessary slippage.

[0076] The first flexible shaft 5.1 travels through the first channel 2.3, and the second flexible shaft 6.1 travels through the second channel 2.4. The first flexible shaft 5.1 and the second flexible shaft 6.1 can be relatively independently installed in the first channel 2.3 and the second channel 2.4. The guide rail 2 provides a channel for the first flexible shaft 5.1 and the second flexible shaft 6.1 to travel while the legs of the front and rear motion mechanism slide within it, making the spatial arrangement more reasonable.

[0077] In this embodiment, to further facilitate the assembly of the front and rear execution components 6, the guide rail 2 is divided into a front guide rail 2.1 and a rear guide rail 2.2. The two sides of the roof frame 1 are provided with recesses for fixing the guide rail 2. The front guide rail 2.1 and the rear guide rail 2.2 are each provided with a first channel 2.3 and a second channel 2.4. The two first channels 2.3 and the two channels can be connected in the recesses. In this way, the length of the guide rail 2 is reduced, and the assembly difficulty of inserting the flexible shaft in the guide rail 2 is reduced.

[0078] Based on the aforementioned front and rear guide rails 2.2, the front motion mechanism is set in the front guide rail 2.1 and the rear motion mechanism is set in the rear guide rail 2.2, realizing the separate installation of the front and rear motion mechanisms, further reducing the installation difficulty, and enabling the two motion mechanisms to be set up independently in separate zones, thereby eliminating the mutual influence between the two motion mechanisms and facilitating spatial arrangement.

[0079] like Figures 5 to 8As shown, as a further embodiment of the front motion mechanism, the slider group includes a first front slider 3.1 and a second front slider 3.2 corresponding to the front glass assembly 3. The first front slider 3.1 and the second front slider 3.2 are provided with a plurality of front sliding feet 3.34 inserted into the motion channel on both sides. The front sliding feet 3.34 are at least provided at the front and rear ends of the front slider to ensure the stability of the movement of the front slider.

[0080] from Figure 6 As can be seen from the above, the front motion mechanism also includes a transmission component 3.6. One end of the transmission component 3.6 is integrally formed with the first front slider 3.1, and the other end of the transmission component 3.6 is in transmission cooperation with the second front slider 3.2. The driving end of the front actuation component 5 is connected to the middle part of the transmission component 3.6, that is, the first flexible shaft 5.1 is connected to the middle part of the transmission component 3.6.

[0081] Optionally, the transmission component 3.6 is hinged to the second front slider 3.2. A vertical slot 3.61 is provided on the transmission component 3.6. The hinged ends of the two can move within a small range within the slot 3.61, so that the transmission of the first front slider 3.1 and the second front slider 3.2 is smoother and the jamming of the front glass assembly 3 during the lifting process is reduced.

[0082] like Figures 5 to 7 As shown, as another transmission method for the first front slider 3.1 and the second front slider 3.2, a linkage component is provided on the first flexible shaft 5.1. The linkage component has a first linkage part corresponding to the rear end of the first front slider 3.1 and a second linkage part corresponding to the front end of the second front slider 3.2, thereby realizing the synchronous transmission of the first front slider 3.1 and the second front slider 3.2.

[0083] In the front motion mechanism, the rocker arm assembly includes a first front rocker arm 3.3. The first front rocker arm 3.3 has a first upper front support leg 3.31 connected to the front end of the front windshield assembly 3, and a first lower front support leg 3.32 and a second lower front support leg 3.33 connected within the first front slider 3.1. The first lower front support leg 3.32 is located at the lower-middle portion of the first upper front support leg 3.31 and the second lower front support leg 3.33. The first front slider 3.1 is provided with a first front lifting slide 3.11 and a straight slide 3.12. The straight slide 3.12 is located at the rear of the first front lifting slide 3.11. The first lower front support leg 3.32 is inserted into the first front lifting slide 3.11 and tilts up at its top. The second lower front support leg 3.33 is inserted into the straight slide 3.12.

[0084] exist Figure 8As can be seen, it should be noted that the front guide rail 2.1 is provided with a lower movement channel 2.5 for the sliding foot assembly of the first front slider 3.1 and the second front slider 3.2 to move within it. The front guide rail 2.1 is also provided with an upper movement channel 2.6 and a front guide seat 3.5 that connects upward to the upper movement channel 2.6. The front guide seat 3.5 is used to guide and maintain the first front rocker arm 3.3 in a tilted state. Its main purpose is to further maintain the tilted posture of the first front rocker arm 3.3.

[0085] Specifically, a front sliding foot 3.34 is provided on the other side of the first front lower support foot 3.32, and an upward slide is provided in the front guide seat 3.5. In the closed state, the front sliding foot 3.34 is at the starting point of the upward slide and corresponds to the height of the lower movement channel 2.5. During the process of the first rocker arm moving to the tilted state, the front sliding foot 3.34 gradually rises with the first front rocker arm 3.3 until the end of the front guide seat 3.5, and finally enters the upper movement channel 2.6, so that the first front rocker arm 3.3 remains in the tilted posture and ensures the movement stability of the front glass assembly 3.

[0086] like Figures 5 to 8 As shown, in the front motion mechanism, the rocker arm assembly includes a second front rocker arm 3.4. The second front rocker arm 3.4 has a second upper front support leg 3.41 connected to the rear end of the front windshield assembly 3, and a third lower front support leg 3.42 and a fourth lower front support leg 3.43 connected within the second front slider 3.2. The fourth lower front support leg 3.43 is located at the lower-middle portion of the second upper front support leg 3.41 and the third lower front support leg 3.42. The second front slider 3.2 is provided with a communicating second front lifting slide. 3.21 and the first guide slide 3.22, the first guide slide 3.22 is located at the opposite front of the second front lifting slide 3.21, and the first guide slide 3.22 has a generally downward guiding trend, the second front lifting slide 3.21 has a generally upward guiding trend, forming a V-shaped slide as a whole, and the third front lower support 3.42 is placed at the starting point of the first guide slide 3.22, and the fourth front lower support 3.43 is placed at the starting point of the second front lifting slide 3.21.

[0087] like Figure 6 As shown, along the direction of travel, the first front lifting slide 3.11 has a relatively flat first section 3.13 and a second section 3.14 with a steeper arc.

[0088] The first guide slide 3.22 is provided with a concave first buffer position and a convex second buffer position in sequence along the traveling direction. A third buffer position is formed between the intersection of the first guide slide 3.22 and the second front lifting slide 3.21. The second front lifting slide 3.21 is provided with a convex fourth buffer position and a concave fifth buffer position in sequence along the traveling direction. The end of the second front lifting slide 3.21 is relatively straight to maintain the stability of the fourth front lower support leg 3.43 in the raised and open states.

[0089] Through the above improvements, the first front rocker arm 3.3 lifts later than the second front rocker arm 3.4 during the lifting process, and the second front rocker arm 3.4 can support the rear end of the front glass assembly 3 to be higher than the front end, thereby preventing dirt or dirty water left on the front glass assembly 3 from entering the vehicle.

[0090] During the lifting process of the front glass assembly 3, the first flexible shaft 5.1 drives the first front slider 3.1 and the second front slider 3.2 to move forward;

[0091] For the first front rocker arm 3.3 and the first front slider 3.1: the first front lower support 3.32 moves in the flat first section 3.13, and the second front lower support 3.33 moves in the straight slide 3.12. At this time, the first front upper support 3.31 does not produce displacement, and the front slider 3.34 corresponds to the lower movement channel 2.5 of the front guide rail 2.1. When the first front lower support 3.32 moves to the starting point of the flat second section 3.14, the first flexible shaft 5.1 continues to drive, the first front lower support 3.32 is lifted along the second section 3.14, and the front slider 3.34 is lifted along the front guide seat 3.5. The first front upper support 3.31 is forced to lift the front end of the front glass assembly 3. Finally, the first front lower support 3.32 is in place at the end of the second section 3.14, and the front slider 3.34 enters the upper movement channel 2.6 of the front guide rail 2.1, causing the front end of the front glass assembly 3 to lift.

[0092] For the second front rocker arm 3.4 and the second front slider 3.2: the third front lower support 3.42 moves down along the first guide slide 3.22 and passes through the first buffer position and the second buffer position in sequence; the fourth front lower support 3.43 moves up along the second front lifting slide 3.21 and passes through the third buffer position and the fourth buffer position in sequence. During this process, the second front rocker arm 3.4 uses the third front lower support 3.42 and the fourth front lower support 3.43 as fulcrums to lift the rear end of the front glass assembly 3, thus tilting the rear end of the front glass assembly 3. Finally, the third front lower support 3.42 is in position at the starting point of the second front lifting slide 3.21, and the fourth front lower support 3.43 is in position at the end of the second front lifting slide 3.21, completing the tilting of the front glass assembly 3.

[0093] The first flexible shaft 5.1 drives the first front slider 3.1 and the second front slider 3.2 to continue moving forward. The first front lower support 3.32 is driven by the end of the second section 3.14, and the second front lower support 3.33 is driven by the end of the straight slide rail 3.12, until the front glass assembly 3 moves to the top of the front roof 1.11 and reaches the open state.

[0094] like Figures 9 to 12 As shown, as a further embodiment of the rear motion mechanism, the slider assembly includes a rear guide seat 4.1 and a first rear slider 4.2 corresponding to the rear glass assembly 4. The rear actuator 6 is connected to the first rear slider 4.2. The rocker arm assembly includes a first rear rocker arm 4.3 that can be tilted within the rear guide seat 4.1 and a second rear rocker arm 4.4 that can be tilted within the first rear slider 4.2. The rear guide seat 4.1 is placed within the guide rail 2, and the rear guide seat 4.1 guides and maintains the first rear rocker arm 4.3 in a tilted state.

[0095] from Figure 12 As can be seen, in the rear motion mechanism, the first rear rocker arm 4.3 has a first upper rear support leg 4.31 connected to the front end of the rear glass assembly 4, a first lower rear support leg 4.32 connected in the rear guide seat 4.1, and a second lower rear support leg 4.33 set to move along the guide rail 2. The rear guide seat 4.1 is provided with a first rear lifting slide 4.11, and the first lower rear support leg 4.32 is located in the first rear lifting slide 4.11. The first rear lifting slide 4.11 connects to the guide rail 2 and limits the first lower rear support leg 4.32 to slide on the upper part of the guide rail 2. The second lower rear support leg 4.33 is hinged to a slide block 4.5. The second lower rear support leg 4.33 can drive the slide block 4.5 to move in the guide rail 2. The slide block 4.5 has multiple sliding feet on both sides that are inserted into both sides of the guide rail 2.

[0096] It should be noted that the rear guide rail 2.2 is provided with a lower movement channel 2.5 for the sliding foot assembly of the slide block 4.5 and the first rear slider 4.2 to move within it. The rear guide rail 2.2 is also provided with an upper movement channel 2.6. The rear guide seat 4.1 is connected to the upper movement channel 2.6. The rear guide seat 4.1 is used to guide and maintain the first rear rocker arm 4.3 in a tilted state. Its main purpose is to further maintain the tilted posture of the first rear rocker arm 4.3.

[0097] Specifically, as the first rear rocker arm 4.3 moves to the tilted position, the first rear lower support foot 4.32 gradually rises with the first rear rocker arm 4.3 until it reaches the end of the rear guide seat 4.1, and finally enters the upper motion channel 2.6, so that the first rear rocker arm 4.3 remains in the tilted position and ensures the motion stability of the rear glass assembly 4.

[0098] In the rear motion mechanism, the second rear rocker arm 4.4 has a second upper rear support leg 4.41 connected to the rear end of the rear window assembly 4, and a third lower rear support leg 4.42 and a fourth lower rear support leg 4.43 connected within the first rear slider 4.2. The first rear slider 4.2 is provided with a second rear lifting slide 4.21 and a second guide slide 4.22 that are connected. The second guide slide 4.22 is located in front of the second rear lifting slide 4.21 and has a generally downward guiding tendency. The third lower rear support leg 4.42 is placed at the starting point of the guide slide so that the third lower rear support leg 4.42 moves downward during the lifting process, and the second rear lifting slide 4.21 has a generally upward guiding tendency. The fourth lower rear support leg 4.43 is placed at the starting point of the second rear lifting slide 4.21 so that the fourth lower rear support leg 4.43 moves upward during the lifting process, thereby lifting the second rear rocker arm 4.4.

[0099] Along the direction of travel, the starting point of the second guide slide 4.22, the end point of the second rear lifting slide 4.21, and the connecting section of the second guide slide 4.22 and the second rear lifting slide 4.21 are relatively flat to maintain the stability of the second rear rocker arm 4.4 during the lifting process and in the open state.

[0100] During the lifting process of the rear glass assembly 4, the second flexible shaft 6.1 first drives the first rear slider 4.2 to move backward;

[0101] For the second rear rocker arm 4.4 and the first rear slider 4.2: the third rear lower support 4.42 moves down along the second guide slide 4.22, and the fourth rear lower support 4.43 moves up along the second rear lifting slide 4.21 to lift the rear end of the rear glass assembly 4. Finally, the third rear lower support 4.42 is in position at the end of the second guide slide 4.22, and the fourth rear lower support 4.43 is in position at the end of the second rear lifting slide 4.21, completing the lifting of the rear end of the front glass assembly 3;

[0102] For the first rear rocker arm 4.3: the second flexible shaft 6.1 continues to drive the first rear slider 4.2 forward, and the third rear lower support leg 4.42 is driven by the end of the second guide slide 4.22. When the rear end of the rear glass assembly 4 is lifted and opened, the first rear rocker arm 4.3 is dragged up by the front end of the rear glass assembly 4. At this time, the first rear lower support leg 4.32 moves along the first rear lifting slide 4.11 and gradually rises from the lower movement channel 2.5 of the rear guide rail 2.2 to the upper movement channel 2.6. Thus, the first rear upper support leg 4.31 is forced to lift the front end of the rear glass assembly 4, and the second rear lower support leg 4.33 drives the slide block 4.5 to slide in the lower movement channel 2.5 of the rear guide rail 2.2 until the front glass assembly 3 moves to the top of the front roof 1.11 and reaches the open state.

[0103] The reset of the front and rear glass assemblies 4 is a reverse action, which will not be elaborated on here. This specific embodiment is merely an explanation of the present invention and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
