Description

Technical Field

[0001] This invention relates to the field of panoramic sunroofs, and in particular to a four-rail segmented panoramic sunroof guide rail. Background Technology

[0002] Panoramic sunroofs are becoming increasingly popular in modern automotive design. They not only enhance the sense of interior space but also increase natural light and improve passenger comfort. However, with technological advancements, panoramic sunroof designs have become more complex and diverse, and their sizes have increased, presenting new challenges for the design and installation of guide rails. Traditional guide rail systems often cannot achieve a perfect fit for panoramic sunroofs. This leads to increased installation complexity and issues such as operational instability and insufficient sealing during use.

[0003] With the development of technology, technicians in related fields have also made a lot of optimizations to car sunroof guide rails. In order to make a more accurate comparison, Chinese patent with publication number CN106427502A discloses a car sunroof guide rail, including a guide rail body, sunroof glass, a first track, a dust-blocking rail, and a dust-blocking strip. In use, a dust-blocking rail is set at the front end of the guide rail body, and a dust-blocking strip made of flexible material is set on the dust-blocking rail. The dust-blocking strip is connected to the front end of the sunroof body. When the sunroof is opened, the sunroof body pulls the dust-blocking strip to slide along the first track of the guide rail body and covers the first track, thereby preventing dust, leaves and other dirt from accumulating on the track and wearing down the sunroof components when the sunroof is open.

[0004] However, the above-mentioned sunroof guide rails still have some shortcomings in actual use:

[0005] The aforementioned device, during the opening of the sunroof, simultaneously drives the sunroof glass and dustproof strip to slide, thereby covering the first track while opening the sunroof to prevent the accumulation of dust, leaves, and other debris. However, in actual use, since the device only covers the first track with the dustproof strip to achieve a dustproof effect, as the dustproof strip slides and extends through the sunroof glass, it will have several wrinkles or creases because the dustproof strip itself is retracted or folded at the second track before the sunroof is opened. This means that after the dustproof strip slides and extends to the first track, it cannot completely and tightly fit the first track. Therefore, while covering the first track with the dustproof strip, it cannot completely prevent fine dust and other impurities from falling into the first track. Furthermore, if these fine dust particles that fall into the dustproof strip or the first track are not dealt with in time, they may cause wear and tear on the dustproof strip during its sliding process.

[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing sunroof rails. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a four-rail segmented panoramic sunroof guide rail, comprising a sunroof slide rail and a sunroof glass slidingly confined thereon, wherein the sunroof slide rail includes:

[0008] The sliding rail base has a pre-drilled opening in the middle for sunroof ventilation, and a sealed base at the upper end for connecting the sunroof glass.

[0009] The mounting slots are symmetrically opened on the slide rail base, corresponding to the sealing base, and the mounting slots are equipped with cover plates.

[0010] A fixing strip is set between the cover plate and the sealing base. A side slide plate is used to limit the movement of the sunroof glass, the fixing strip and the cover plate. Several drive sliders connected to the sunroof glass are set on the underside of the side slide plate. A drive component is connected to the sealing base to drive the drive sliders and the sunroof glass to slide and adjust.

[0011] Preferably, the side slide plate is recessed into a groove towards the slide rail base, so that a water guide groove is formed together between the sunroof glass, the fixing strip, the side slide plate and the cover plate.

[0012] Preferably, the sealing base has vertical slide rails and limiting horizontal rails symmetrically formed on the sunroof glass, the driving slider is inserted into the limiting horizontal rail, and the sliding limit is located in the vertical slide rail.

[0013] Preferably, the driving component includes a driven rotating rod on the sealed base corresponding to the driving slider, a driven lever is sleeved on the driven rotating rod, and the driven rotating rod is slidably limited to the driven lever by a limiting block.

[0014] Preferably, the driven lever plate has a limit groove and a guide groove respectively corresponding to the driven rotating rod and the limit block, and the limit groove and the guide groove are connected.

[0015] Preferably, a reset spring is provided between the limiting slot and the limiting block.

[0016] Preferably, a drive rod is provided on the sealed base corresponding to the driven rod, and the drive rod and all the driven rods are connected by a bevel gear transmission.

[0017] Preferably, all the aforementioned drive sliders share a common connecting guide rod located at a limited position on the vertical slide rail.

[0018] Preferably, a limiting groove is formed on the cover plate corresponding to the sliding path of the driving slider.

[0019] Preferably, the side slide plate is provided with a vertical extension plate on the side near the slide rail base to cover the limiting slide groove.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] I. This invention constructs a guide rail system by symmetrically forming vertical slide rails and several limiting horizontal rails on both sides of the sunroof glass at the sealed base. When the drive slider and one of the slidable sunroof glass slides are adjusted, they are always guided and restricted by the vertical guide rails, ensuring that the movement direction and range of the slidable glass meet the design requirements.

[0022] Second, this invention drives the side slide plate to slide longitudinally relative to the slide rail base by driving the slider and the opening and closing movement of the sunroof glass. When the sunroof is closed, the water channel at the side slide plate is guided to sink so as to drain rainwater in time. When the sunroof is open, it is driven to slide and protrude from the cover plate at the same time, so as to make it easy to use the airflow of the vehicle to blow away dust, prevent dust accumulation, and extend the service life of the guide rail.

[0023] Third, this invention utilizes the cooperation between the cover plate and the side sliding plate on the side of the sunroof glass to effectively cover the guide rail system, preventing debris from entering the guide rail and extending its service life. Furthermore, through the cooperation between the sunroof glass, drive slider, cover plate, driven plug, exhaust pipe, air duct, and air duct channel, gas is guided to blow away the side sliding plate, thereby further preventing dust from adhering to the side sliding plate and affecting the service life of the guide rail.

[0037] The following is in conjunction with the appendix Figure 1 To be continued Figure 11 The embodiments of the present invention will be described in detail below.

[0038] This application discloses a four-rail segmented panoramic sunroof guide rail. This application is mainly used in the process of using sunroof glass guide rails. Technically, the interaction between the driving slider and the limiting horizontal and vertical rails effectively guides and limits the sliding path and range of the sunroof glass. Specifically, during the sunroof glass sliding adjustment process, a water-guiding groove is formed at the guide rail, allowing rainwater to be promptly drained from the guide rail when the sunroof is closed. Furthermore, this application also extends the service life of the guide rail by guiding the water-guiding groove to protrude beyond the cover plate during the sunroof glass opening process, facilitating timely cleaning of dust at the water-guiding groove.

[0039] Example 1: Refer to Figure 1 and Figure 2 As shown, a four-rail segmented panoramic sunroof guide rail includes a sunroof rail 1 and a sunroof glass 2 that slides and is limited thereon. It should be noted that panoramic sunroofs are generally divided into fixed panoramic sunroofs and operable panoramic sunroofs. Operable panoramic sunroofs are mostly composed of two pieces of glass, front and back. In this example, the panoramic sunroof is implemented based on two pieces of sunroof glass 2, that is, one piece of glass is fixed and the other piece of glass is movable.

[0040] Reference Figures 2 to 4 As shown, the sunroof track 1 includes:

[0041] The sliding rail base 10 has a pre-drilled opening in the middle for sunroof ventilation. At its upper limit, there is a sealing base 11 for connecting two sunroof glass panes 2. The sealing base 11 has two openings corresponding to the two sunroof glass panes 2, and the two sunroof glass panes 2 cover the two openings respectively. One sunroof glass pane 2 is fixedly located at one of the openings, and the other sunroof glass pane 2 is attached to the other opening to facilitate ventilation inside the vehicle. At the same time, several sealing strips are filled between the sealing base 11 and the two sunroof glass panes 2 to seal and waterproof the sunroof glass panes 2, sealing base 11 and sliding rail base 10 when the sunroof is closed. Of course, sunshades and other items can also be connected to the lower side of the sealing base 11.

[0042] Mounting slot 12 is symmetrically opened on slide rail base 10 corresponding to sealing base 11, and a cover plate 120 is provided on mounting slot 12.

[0043] A fixing strip 13 is disposed between the cover plate 120 and the sealing base 11. A side slide plate 130 is provided between the sunroof glass 2, the fixing strip 13 and the cover plate 120 to limit the movement. A number of drive sliders 131 connected to the sunroof glass 2 are provided on the lower side of the side slide plate 130. The drive sliders 131 are all limited to the slidable sunroof glass 2. A drive component 14 is connected to the sealing base 11 to drive the drive sliders 131 and the sunroof glass 2 to slide and adjust.

[0044] In use, the drive component 14 drives the drive slider 131 and the connected sunroof glass 2 to slide and adjust, so as to open the opening covered by the sunroof glass 2 to allow ventilation inside the vehicle. During the sliding process of the sunroof glass 2 and the drive slider 131, the sliding path of the sunroof glass 2 and the drive slider 131 is limited and guided by the slide rail base 10 and the sealing base 11. At the same time, the sliding path of the drive slider 131 is covered by the cover plate 120 and the side slide plate 130 to prevent debris from falling onto the track during the sunroof opening process, causing wear on the drive slider 131, slide rail base 10 and sealing base 11 and thus affecting the service life of the guide rail.

[0045] Reference Figure 3 and Figure 4As shown, the side sliding plate 130 is recessed into a groove towards the sliding rail base 10, so that a water guiding channel 1300 is formed between the sunroof glass 2, the fixing strip 13, the side sliding plate 130, and the cover plate 120. The water guiding channel 1300 formed at the side sliding plate 130 allows rainwater on the surface of the sunroof to be guided and drained during the overall closure of the sunroof. As an optional implementation, a drain pipe (not shown in the figure) can be inserted through the fixing strip 13 and connected to the water guiding channel 1300, thereby facilitating the timely drainage of rainwater in the water guiding channel 1300 when the sunroof is closed.

[0046] Reference Figure 4 and Figure 5 As shown, vertical slide rails 15 and limiting horizontal rails 16 are symmetrically formed on the sealing base 11 corresponding to the sunroof glass 2. Several limiting horizontal rails 16 on the same side are provided so that the drive sliders 131 can be inserted into them. The drive sliders 131 slide and are limited within the vertical slide rails 15. Initially, the drive sliders 131 on the same side are simultaneously inserted into several limiting horizontal rails 16 and vertical slide rails 15 to close and position the sunroof glass 2.

[0047] In use, the drive slider 131 is disengaged from the limit rail 16 by the drive component 14, and the drive slider 131 is guided to slide in the vertical direction by the vertical slide rail 15, thereby driving one of the connected sunroof glass 2 to slide and adjust synchronously so as to open the corresponding opening at the sealing base 11.

[0048] Reference Figures 5 to 7 As shown, the driving component 14 includes a driven rotating rod 140 on the sealing base 11 corresponding to the driving slider 131. A driven lever 141 is sleeved on the driven rotating rod 140 and abuts against the lower side of the driving slider 131. The driven rotating rod 140 is slidably limited on the driven lever 141 by a limiting block 142. In use, by driving the driven rotating rod 140 to rotate, the driven rotating rod 140 drives the limiting block 142 and the driven lever 141 to rotate around the driven rotating rod 140 as an axis. During the rotation of the driven lever 141, it pushes the abutting driving slider 131 upward to disengage from the limiting horizontal rail 16. At the same time, it drives the sunroof glass 2 connected to the driving slider 131 to disengage from the sealing base 11. Then, it drives the driving slider 131 and the sunroof glass 2 to slide along the vertical slide rail 15 towards the other sunroof glass 2, so as to open the opening on the sealing base 11 and facilitate the ventilation of the vehicle interior.

[0049] Reference Figure 7As shown, the driven lever 141 has a limiting groove 143 and a guide groove 144 respectively corresponding to the driven rotating rod 140 and the limiting block 142. The limiting groove 143 and the guide groove 144 are connected. The limiting block 142 is slidably limited within the guide groove 144, so that when the driven rotating rod 140 drives the limiting block 142 and the driven lever 141 to rotate, the limiting block 142 and the driven rotating rod 140 can slide and adjust along the limiting groove 143 and the guide groove 144.

[0050] Furthermore, referring to Figure 7 As shown, a return spring 145 is provided between the limiting slot 143 and the limiting block 142. In the initial state, the return spring 145 is in a compressed state, and the driven plate 141 is horizontally limited on the sealing base 11 to fit against the lower side of the drive slider 131, which facilitates the overall closure of the sunroof. Under the reset push of the connected return spring 145, the driven plate 141 tends to slide in opposite directions with the limiting block 142 and the driven rotating rod 140. After being driven by the return spring 145, the horizontal driven plate 141 will abut against the sealing base 11 to limit the sliding movement of the driven plate 141 along the limiting slot 143 and the guide groove 144.

[0051] In use, after the driven rotating rod 140 drives the limiting block 142 and the driven lever 141 to rotate and tilt, the sealing base 11 no longer restricts the sliding of the driven lever 141. Under the drive of the connected return spring 145, the driven lever 141 further slides away from the limiting block 142 and the driven rotating rod 140. At this time, since the driven rotating rod 140 is limited on the sealing base 11, the driven lever 141 will move away from the limiting block 142 and the driven rotating rod 140 under the drive of the connected return spring 145. The driven slider 131 slides in the direction of the fixed strip 16, causing it to tend to disengage from the limiting horizontal rail 16. As the driven lever 140 continues to rotate, the driven lever 141 gradually rotates from a horizontal position to a vertical position and slides upward by the tendency of the return spring 145, causing the driven slider 131 to completely disengage from the limiting horizontal rail 16. Then, by driving the driven slider 131 and the connected sunroof glass 2 to slide and adjust away from the fixed strip 13, the sunroof can be opened.

[0052] When the sunroof needs to be closed, the drive slider 131 and the slidable sunroof glass 2 are driven to slide in the opposite direction. After the drive slider 131 slides to the upper side of the vertical driven plate 141, a downward force is applied to the driven plate 141, causing the driven plate 141 to tend to slide downward under the gravity of the drive slider 131 and the sunroof glass 2. At this time, the driven rod 140, the limiting block 142 and the driven plate 141 are rotated in the opposite direction. Under the combined action of the rotation of the driven rod 140, the downward pressure of the gravity of the drive slider 131 and the slidable sunroof glass 2, and the abutment between the sealing base 11 and the driven plate 141, the driven plate 141 is driven to rotate back to a horizontal position and be limited on the sealing base 11. The drive slider 131 and the slidable sunroof glass 2 are reset and re-close the opening on the sunroof. At the same time, the return spring 145 is re-compressed, storing elastic potential energy, preparing for the next opening of the sunroof.

[0053] Of course, as an optional implementation, the two ends of the driven dial 141 are preferably arranged in an arc shape so that they can rotate and reset smoothly during rotation.

[0054] Reference Figures 6 to 8 As shown, in order to maintain the synchronization of the sliding adjustment of several drive sliders 131, as an optional implementation, a drive rod 17 is provided on the sealed base 11 corresponding to the driven rod 140. The drive rod 17 and all the driven rods 140 are connected by a bevel gear transmission. In use, the drive rod 17 is driven to rotate by existing motor technology. After the drive rod 17 rotates, the meshing transmission between the bevel gears on the driven rods 140 and the drive rods 17 achieves the effect of synchronous rotation between the drive rod 17 and all the driven rods 140, thereby synchronously driving the driven dial 141 to rotate and adjust the drive slider 131, achieving the effect of maintaining the synchronous stability of the sliding adjustment of the drive slider.

[0055] Of course, in order to keep the rotation of the drive rods 17 on both sides of the sunroof glass 2 synchronized, the two drive rods 17 can also be driven by a synchronous belt to make them rotate synchronously, so as to further ensure the uniformity and stability of the sliding adjustment of the several drive sliders 131.

[0056] Reference Figure 5 As shown, all the drive sliders 131 are connected by a connecting guide rod 18 located at the vertical slide rail 15. As an optional implementation, the drive sliders 131, the connecting guide rod 18 and the sunroof glass 2 can be slid together by an electric push rod. It is only necessary to adjust the forward and backward sliding of the drive sliders 131, the connecting guide rod 18 and the slidable sunroof glass 2, while also allowing a certain degree of displacement in the vertical section so that the drive sliders 131 can disengage from the limiting horizontal rail 16.

[0057] An electric push rod (not shown in the figure) is also connected to one of the drive sliders 131 near the end of the sunroof glass 2. The telescopic section of the electric push rod (not shown in the figure) is connected to the drive slider 131. The electric push rod (not shown in the figure) is limited on the slide rail base 10 by the mounting seat and allows the electric push rod (not shown in the figure) to slide vertically. In use, the rotation of the driven plate 141 drives the drive slider 131 and the slidable sunroof glass 2 to disengage from the limiting horizontal rail 16. Then, the telescopic movement of the electric push rod (not shown in the figure) drives the drive slider 131, the connecting guide rod 18 and the sunroof glass 2 to slide along the vertical slide rail 15, thereby achieving the effect of opening and closing the sunroof.

[0058] Reference Figure 8 As shown, to prevent the cover plate 120 from obstructing the sliding path of the drive slider 131 and affecting its sliding range, a limiting groove 19 is formed on the cover plate 120 corresponding to the sliding path of the drive slider 131. When the driven slider 131 is driven to slide towards the cover plate 120 by the rotation of the driven dial 141, the drive slider 131 will be driven by the driven dial 141 to abut against the limiting groove 19. At the same time, the drive slider 131 and the sunroof glass 2 as a whole will slide away from the sealing base 11, so that the slidable sunroof glass 2 will disengage from the sealing base 11. During the sliding process of the drive slider 131, the opposing side slide plate 130 will be pushed further away from the sealing base 11, so that the side arc plate will gradually protrude from the slide rail base 10, that is, the water guide groove 1300 will be driven to move upward and protrude from the fixing strip 13 and the cover plate 120.

[0059] Through the cooperation between the sunroof glass 2, the drive slider 131 and the side slide plate 130, when the sunroof glass 2 is closed, the side slide plate 130 is driven to sink synchronously, forming a water channel 1300 on the guide rail surface to guide and drain rainwater. When the sunroof glass 2 is open, the side slide plate 130 is driven to move upward, causing the water channel 1300 to move upward and completely protrude beyond the cover plate 120, so as to remove the dust and impurities accumulated in the water channel 1300.

[0060] Reference Figure 8 As shown, an extension plate 132 is provided on the side of the side slide plate 130 near the slide rail base 10 to cover the limiting slide groove 19.

[0061] Of course, as a feasible implementation, the driven lever 140, driven dial 141 and driven shaft can also be directly moved down and limited to the slide rail base 10. Correspondingly, the lower side of the drive slider 131 continues to extend downward, while its upper end remains in contact with the lower side of the side slide plate 130.

[0062] In this state, the limiting groove 19 is no longer provided on the cover plate 120, and the side slide plate 130 is no longer provided with a vertical extension plate 132.

[0063] Based on this, when the sunroof glass 2 is closed, it will cause the side slide plate 130 to sink to form a water channel 1300. When the sunroof glass 2 is open, it will cause the side slide plate 130 to move upward and protrude from the cover plate 120. At the same time, the water channel 1300 will temporarily disappear as the side slide plate 130 moves upward relative to the cover plate 120. That is, the water channel 1300 will be temporarily hidden. During the sunroof opening process, even if dust falls onto the protruding side slide plate 130, it will be blown off by the wind during the high-speed driving of the vehicle, thereby greatly avoiding the problem of dust accumulation at the side slide plate 130 (inside the water channel 1300).

[0064] Example 2: Refer to Figures 8 to 11 As shown, based on Embodiment 1, since a water channel 1300 is formed between the fixing strip 13, the cover plate 120 and the sunroof glass 2 by the sinking of the side sliding plate 130, that is, when the sunroof glass 2 is closed, the side sliding plate 130 will also sink accordingly. Although it can guide the rainwater falling on it in time during rainy days, in other weather conditions, fine dust in the air may fall and adhere to the wall of the water channel 1300, thus affecting the smoothness of the sliding of the side sliding plate 130.

[0065] Based on this, a sealing plate 3 is symmetrically arranged on both the cover plate 120 and the slide rail base 10. The sealing plate 3 is symmetrically distributed on both sides of the drive slider 131 of the sunroof glass 2, and a cavity is formed by the cover plate 120, the slide rail base 10 and the sealing plate 3. Several air holes 30 are provided at one end of the sealing plate 3 near the fixing strip 13 to communicate with the outside. A driven plug 31 slides and fits in the cavity, and an exhaust pipe 32 is connected to the driven plug 31 to exit the cavity. The exhaust pipe 32 has a plurality of vent holes 33 evenly formed on it. The vent holes 33 are preferably arranged on one side close to the driven plug 31. The end of the exhaust pipe 32 that extends out of the cavity is rotatably limited by a rotating ring 34. The rotating ring 34 is connected to a guide pipe 35 that is connected to a plurality of drive sliders 131. A guide channel 36 is provided between the drive sliders 131 and the guide pipes 35. The gas in the guide pipes 35 is guided and blown to the side slide plate 130 through the guide channel 36.

[0066] When the drive slider 131 and sunroof glass 2 are opened, the air duct 35 and rotating ring 34 are driven to deflect and slide. The sliding of the rotating ring 34 pulls the exhaust pipe 32 and the driven plug 31 in the cavity. Since the sealing plate 3 is provided with air holes 30 that are connected to the outside, the driven plug 31 will cause outside air to enter the cavity through the air holes 30 during the sliding process. The side of the driven plug 31 away from the exhaust pipe 32 will also be compressed as the driven plug 31 slides away from the fixing strip 13. The internal volume drives the gas from the driven plug 31 near the exhaust pipe 32 to enter the exhaust pipe 32, rotating ring 34, air guide pipe 35 and several driving sliders 131 through several vent holes 33 on the exhaust pipe 32. The gas is then blown from the air guide channels 36 at the several driving sliders 131 to the side slide plate 130, thereby blowing the wall of the water guide groove 1300, effectively preventing fine dust from adhering to the wall of the water guide groove 1300, thus ensuring that the side slide plate 130 can always maintain a smooth sliding state.

[0067] During operation: First, the drive slider 131 is limited within the limiting horizontal rail 16 and the vertical slide rail 15, guiding the slidable sunroof glass 2 to be positioned and covered on the sealing base 11, thereby forming an initial sealing effect at the sunroof opening. At the same time, by guiding the side slide plate 130 to sink into the sealing base 11, a water guide groove 1300 is formed to guide rainwater at the sunroof in a timely manner when the sunroof is closed.

[0068] Step 2: The drive slider 131 is guided to disengage from the limiting horizontal rail 16 by the drive component 14, and then the drive slider 131 and the slidable sunroof glass 2 are driven to slide to open the sunroof. During the process of driving the drive slider 131 to disengage from the limiting horizontal rail 16, the side slide plate 130 (water guide channel 1300) is simultaneously driven to slide and protrude from the cover plate 120, using the airflow during vehicle movement to blow away dust, effectively preventing dust accumulation and extending the service life of the guide rail.

[0069] Step 3: When the sunroof needs to be closed, drive the sunroof glass 2 and the drive slider 131 to slide in the opposite direction, and then drive the drive slider 131 to be stopped at the limit rail 16. The sunroof glass 2 will be reset and abut against the sealing base 11, thus sealing the sunroof again. At the same time, the side slide plate 130 will move down and reset to continue to drain rainwater.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and not restrictive.

[0071] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
