DETAILED DESCRIPTION

[0036] The present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0037] Example:

[0038] Reference Figure 1 - Fig.11 The present invention discloses an anti-derailment skylight guide rail assembly, comprising a mounting plate 1, a guide rail 4 is fixedly connected to the top center of the mounting plate 1, and both sides of the top of the guide rail 4 are convexly formed with a buckling portion 5;

[0039] The slider assembly 2 includes a slide 201 and a buckle block 202. The slide 201 is placed on the top of the guide rail 4. The front and rear edges of the slide 201 are provided with mounting holes 6 for connecting to the skylight. The bottom of the slide 201 is provided with mounting grooves 7 on both sides of the guide rail 4. The buckle block 202 is slidably connected in the mounting groove 7. A buckle part 2 8 is formed on a protrusion on one side of the buckle block 202 close to the guide rail 4 and is buckled with a buckle part 1 5. A connecting block 9 is fixedly connected to the upper side wall of the buckle block 202 provided with the buckle part 2 8.

[0040] The buffer assembly 3 includes a piston 301, a slide 201 located above the mounting groove 7 and having an exhaust groove 10 extending horizontally therethrough, a suction groove 11 extending downwardly therethrough and penetrating the slide 201, the exhaust groove 10 being located on both sides of the suction groove 11 and having slide grooves 12 connected to the mounting groove 7, the slide groove 12 being slidably connected with the piston 301, the bottom of the piston 301 extending out of the slide groove 12 and being fixedly connected with a positioning rod 13, the front and rear sides of the mounting groove 7 being fixedly connected with a positioning plate 14, a positioning groove 15 being provided in the positioning plate 14 along a vertical direction, the positioning rod 13 passing through the connecting block 9 and being inserted into the positioning groove 15.

[0041] In this embodiment, observe Figure 1 and Figure 2 It can be found that by providing a mounting plate 1, it can be fixedly connected to the skylight frame, and then a guide rail 4 is fixedly connected to the top of the mounting plate 1, and a slider assembly 2 is slidably provided on the top of the guide rail 4, so that the slider assembly 2 can slide along the length direction of the guide rail 4, and then combined with Figure 3 , Figure 7 and Figure 8 It can be seen that mounting holes 6 are provided at the front and rear edges of the slide platform 201 of the slider assembly 2, so that the skylight can be installed as shown in the figure. Figure 3 and Figure 8 As shown in B, the skylight and the slider assembly 2 are stably connected together by bolt fasteners so that the skylight Figure 1 The installation shown in A can reduce the difficulty of installing the skylight.

[0042] When the sunroof is open, when the vehicle encounters bumps during driving, the shaking force of the vehicle will be transmitted to the guide rail slider connected to the sunroof, causing the guide rail slider to shake on the sunroof guide rail, causing damage to the sunroof guide rail. As the driving time increases, the sunroof will age more, causing the gap between the guide rail 4 and the slider assembly 2 to increase, resulting in the sunroof being separated from the sunroof guide rail during bumps, causing the sunroof to fall off.

[0043] So observe Figure 5It can be found that buckling parts 5 are provided on both sides of the top of the guide rail 4, and then an installation groove 7 is opened at the bottom of the slide 201, and a buckling block 202 is connected to the installation groove 7. The buckling block 202 is protruded on one side of the guide rail 4 to form a buckling part 28. When the slider assembly 2 is placed on the guide rail 4, the two buckling blocks 202 and the buckling part 28 on the buckling block 202 are buckled with the buckling parts 5 on both sides of the guide rail 4 to achieve the installation of the slider assembly 2. At this time, after the skylight is bumped, the skylight moves up under the action of force and moves up with the slide 201 at the same time. Then the slide 201 pulls the buckling block 202 up. At this time, the buckling part 28 on the buckling block 202 will buckle with the buckling part 15 on the guide rail 4, applying tension to the slide 201 to prevent it from falling off the guide rail 4, which can effectively improve the anti-falling performance of the skylight.

[0044] When the sunroof moves upward under the action of the bumping force, the buckling part 2 8 and the buckling part 1 5 will prevent it from being separated from the guide rail 4, but a large pulling force will still be applied to the guide rail 4. Figure 5 It can also be found that the snap-fit ​​block 202 is slidably connected in the mounting groove 7. At this time, when the sunroof moves upward in a bumpy manner, the snap-fit ​​block 202 will slide in the mounting groove 7 to unload the force, which can reduce the force on the snap-fit ​​part 1 5 and the snap-fit ​​part 2 8, effectively extend the service life of the snap-fit ​​part 1 5 and the snap-fit ​​part 2 8, and enhance the anti-derailment effect of the sunroof.

[0045] Due to the sliding effect between the buckling block 202 and the slide 201, when the skylight loses the impact of the bump and falls, the slide 201 and the guide rail 4 will contact and collide, so that the impact generated by the collision will cause secondary damage to the skylight, affecting the service life of the skylight.

[0046] So in Figure 6 We can see that an exhaust groove 10 is horizontally provided at the top of the slide 201 above the mounting groove 7, and an air suction groove 11 is downwardly provided in the middle of the exhaust groove 10 and penetrates the slide 201, and then slide grooves 12 connected to the mounting groove 7 are provided on both sides of the exhaust groove 10 located at the air suction groove 11, and then a piston 301 is slidably connected in the slide groove 12, so that the bottom of the piston 301 extends out of the slide groove 12, and a positioning rod 13 is fixedly connected to the bottom of the piston 301, and at the same time, a positioning plate 14 is fixedly connected to the front and rear sides of the mounting groove 7, and a positioning groove 15 is provided in the positioning plate 14 along the vertical direction, and finally a connecting block 9 is fixedly connected above the side wall of the snap-fitting portion 8 of the snap-fitting block 202, so that the positioning rod 13 passes through the connecting block 9 and is inserted into the positioning groove 15.

[0047] At this time, when the skylight moves upward under the action of the bumping force, the skylight moves upward with the slide 201, and the buckle block 202 is buckled with the buckle part 1 5 through the buckle part 2 8 and cannot move. At this time, the buckle block 202 slides relatively with the slide 201, so that the connecting block 9 pulls the positioning rod 13 to move downward in the positioning groove 15, and at the same time pulls the piston 301 to move downward in the slide groove 12, so that negative pressure suction is generated in the slide groove 12, and the openings of the exhaust groove 10 and the suction groove 11 are set to be small, which reduces the amount of air suction, thereby utilizing the air resistance. The first buffer is applied to the sunroof to reduce the bumping force on the sunroof; then when the bumping force disappears, the sunroof presses the slide 201 downward, causing the slide 201 and the snap-fit ​​block 202 to slide relative to each other in opposite directions. At this time, the piston 301 is pressed into the slide groove 12, causing the air in the slide groove 12 to be pressed and ejected outward. The air damping is used to apply a second buffer to the sunroof to reduce the impact when the sunroof falls back, which can effectively improve the protection effect of the sunroof, while improving the protection of the guide rail assembly and extending the service life of the guide rail assembly.

[0048] In a further preferred embodiment of the present invention, Figure 2 , Figure 6 - Fig.10 As shown, the buffer assembly 3 further includes a spoiler 302, a track groove 16 is provided near the opening of the exhaust groove 10, two spoilers 302 are slidably connected in the track groove 16, the two spoilers 302 are in contact with each other, and a plurality of exhaust holes 17 are provided on the side wall of the spoiler 302 at equal intervals in the horizontal direction;

[0049] Both ends of the track groove 16 are provided with through grooves 18 connected to the mounting hole 6, and the middle of the through groove 18 is provided with a rebound groove 19, in which a rebound plate 20 is slidably connected, and a spring 21 is fixedly connected between the side of the rebound plate 20 away from the mounting hole 6 and the side wall of the rebound groove 19, and the opposite ends of the two spoilers 302 pass through the two rebound plates 20 respectively and extend into the corresponding mounting hole 6;

[0050] One end of the spoiler 302 extending into the mounting hole 6 is processed with a curved surface 22 coaxial with the mounting hole 6, and a guide surface 23 is processed at a position of the curved surface 22 close to the opening of the mounting hole 6;

[0051] The opening position of the exhaust groove 10 is gradually inclined upward from the inside to the outside to form a guide port 24 .

[0052] In this embodiment, when the skylight falls back from the bump, air will be ejected from the opening of the exhaust slot 10, and the observation Figure 6It can be found that by opening a track groove 16 near the opening of the exhaust slot 10, two spoilers 302 are connected in the track groove 16, and the side walls of the spoilers 302 are evenly spaced in the horizontal direction to open a plurality of exhaust holes 17, the spoilers 302 can further reduce the air passing cross-section, so that the exhaust airflow is more concentrated, thereby increasing the exhaust speed of the airflow, so that when the skylight falls back, the airflow ejected from the opening of the exhaust slot 10 has a greater impact, and at the same time Figure 6 It can also be found that the opening position of the exhaust groove 10 is gradually inclined upward from the inside to the outside to form a guide port 24, so that the jetted airflow moves upward obliquely, thereby flushing the edge of the skylight, and is used to clean the floating dust on the edge of the skylight to keep the skylight clean and ensure its normal use.

[0053] Since the exhaust slot 10 has two openings, only one of the openings will blow toward the edge of the skylight, which will result in a poor blowing effect. Figure 7 - Fig.10 It can be found that the two spoilers 302 are brought into contact with each other, and then through slots 18 communicating with the mounting hole 6 are opened at both ends of the track slot 16, and then a rebound slot 19 is opened in the middle of the through slot 18, and a rebound plate 20 is slidably connected in the rebound slot 19, and a spring 21 is fixedly connected between the side of the rebound plate 20 away from the mounting hole 6 and the side wall of the rebound slot 19, and then the opposite ends of the two spoilers 302 are respectively passed through the two rebound plates 20 and extended into the corresponding mounting holes 6. At this time, when no bolts are installed in the mounting holes 6, the spoilers 302 remain inserted into the mounting holes 6 under the rebound action of the rebound plates 20 and the spring 21. At this time, the two spoilers 302 are as shown in FIG. Figure 7 and Fig.10 As shown, the exhaust holes 17 overlap one by one, so that air can be discharged normally through the exhaust holes 17.

[0054] When the skylight and the slider assembly 2 are Figure 2 After the installation is performed in the manner shown, the presence of the bolts will squeeze the space in the mounting hole 6, and the bolts will squeeze the spoiler 302 into the mounting hole 6, so that the state between the two spoilers 302 is as shown in FIG. Figure 8 As shown, the exhaust holes 17 between the two spoilers 302 are staggered so that the air cannot be discharged therethrough. Therefore, more air will be discharged at another opening of the exhaust slot 10, which can effectively improve the dust cleaning effect.

[0055] Since the spoiler 302 is inserted into the mounting hole 6, the bolts will be blocked by the spoiler 302 during installation. Fig.10It can be found that the end of the spoiler 302 extending into the mounting hole 6 is processed with a curved surface 22 coaxial with the mounting hole 6, and the curved surface 22 is processed with a guide surface 23 near the opening of the mounting hole 6. In order to facilitate installation, the bolt is usually also chamfered at the threaded end. Therefore, when the bolt is installed, the chamfer at the end of the bolt will squeeze the guide surface 23, so that the guide surface 23 converts the pressure into a lateral movement force, which is used to squeeze the spoiler 302 into the mounting hole 6. The curved surface 22 coaxial with the mounting hole 6 can make the contact between the bolt and the guide surface 23 more uniform, and the pressure is more dispersed, thereby reducing damage to the spoiler 302.

[0056] In a further preferred embodiment of the present invention, Figure 5 and Figure 6 As shown, the weight of the snap-fit ​​block 202 is greater than the weight of the snap-fit ​​portion 28, and there is a space for shaking between the snap-fit ​​block 202 and the positioning plate 14;

[0057] The buckling portion 1 5 extends obliquely downward from one side of the guide rail 4 to form a buckling point 1 25 , and the buckling portion 2 8 extends obliquely upward from one side of the buckling block 202 to form a buckling point 26 , and the extension directions of the buckling point 1 25 and the buckling point 2 26 are opposite.

[0058] In this embodiment, by making the weight of the snap-fit ​​block 202 greater than the weight of the snap-fit ​​portion 8, the center of gravity of the snap-fit ​​block 202 and the snap-fit ​​portion 8 can be located outside the positioning rod 13. At this time, when the slider assembly 2 is not connected to the guide rail 4, the snap-fit ​​block 202 will be offset against the positioning rod 13 under the action of gravity, so that the snap-fit ​​block 202 is as shown in FIG. Figure 5 As shown in the middle state, after the slider assembly 2 and the guide rail 4 are installed, when the slider assembly 2 moves upward under the action of the bumping impact, the two snap-fit ​​blocks 202 will actively approach the guide rail 4, so that the snap-fit ​​part 2 8 is always below the snap-fit ​​part 1 5, which can ensure the stable snap-fitting of the snap-fit ​​part 2 8 and the snap-fit ​​part 1 5, making the anti-slip effect of the guide rail assembly more stable.

[0059] And in Figure 5 and Figure 6 It can also be found that the side of the buckling part 5 away from the guide rail 4 is extended obliquely downward to form a buckling point 25, and the side of the buckling part 2 8 away from the buckling block 202 is extended obliquely upward to form a buckling point 26. The extension directions of the buckling point 25 and the buckling point 26 are opposite, so that the buckling part 1 5 and the buckling part 2 8 are resisted by the buckling point 1 25 and the buckling point 2 26 when they are buckled together, thereby preventing them from shaking left and right and loosening, thereby further enhancing the anti-slip performance.

[0060] In a further preferred embodiment of the present invention, Figure 6As shown, when the slide 201 is placed on the guide rail 4, the top and bottom of the snap-fit ​​block 202 are in contact with the top of the mounting plate 1 and the inner top wall of the mounting groove 7 respectively, and the two snap points 26 are in contact with the side walls of the guide rail 4.

[0061] In this embodiment, when the slide 201 is placed on the guide rail 4, the top and bottom of the snap-fit ​​block 202 are in contact with the top of the mounting plate 1 and the inner top wall of the mounting groove 7 respectively. The snap-fit ​​block 202 can be used to provide support for the slide 201 and share the pressure of the slide 201 on the guide rail 4, thereby reducing the wear caused by sliding when the sunroof is opened and closed, and extending the service life of the guide rail assembly.

[0062] When the slide 201 is placed on the guide rail 4, the two buckle points 26 are in contact with the side walls of the guide rail 4. The contact between the two buckle points 26 and the guide rail 4 can be used to limit the left and right movement, so that the sliding block assembly 2 can slide on the guide rail 4 more stably.

[0063] In a further preferred embodiment of the present invention, Figure 6 As shown, the top surface of the guide rail 4 is provided with an oil storage groove 27 along the length direction, and at least two oil storage grooves 27 are arranged at intervals along the width direction of the guide rail 4, so that when the slide 201 is placed on the guide rail 4, a lubrication space is formed between the slide 201 and the guide rail 4.

[0064] In this embodiment, an oil storage groove 27 is opened on the top surface of the guide rail 4 along the length direction, and at least two oil storage grooves 27 are arranged at intervals along the width direction of the guide rail 4. When the slide 201 is placed on the guide rail 4, a lubrication space is formed between the slide 201 and the guide rail 4, which can be used to fill lubricating oil between the slider assembly 2 and the guide rail 4, greatly reducing the damage to the slider assembly 2 when sliding, thereby further extending the service life of the guide rail assembly.

[0065] In a further preferred embodiment of the present invention, Figure 1 and Figure 7 As shown, the front and rear ends of the mounting plate 1 are fixedly connected with positioning blocks 28, the side of the positioning block 28 close to the slide 201 is fixedly connected with an insert block 29, and the front and rear outer walls of the slide 201 are provided with slots 30 for inserting the insert block 29.

[0066] In this embodiment, a positioning block 28 is fixedly connected to the front and rear ends of the mounting plate 1, and an insert block 29 is fixedly connected to the side of the positioning block 28 close to the slide 201. Then, slots 30 for inserting the insert block 29 are opened on the front and rear outer walls of the slide 201. When the sunroof is opened to the maximum value or closed, the slide 201 is plugged into the insert block 29 to provide a limit for the slide 201, thereby preventing the sunroof from shaking with the vehicle when not in use, and making the sunroof more stable.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
