Description

Technical Field

[0001] This utility model relates to the field of vehicle platform technology, and in particular to a slide rail structure and a vehicle slide rail platform. Background Technology

[0002] Vehicle-mounted platforms are typically installed on the roof of a car to carry and secure various items (such as luggage). Traditional vehicle-mounted platforms often use a rigid straight-bar structure, which, while sturdy and durable, lacks flexibility and is difficult to steer or adjust in shape. Furthermore, due to the height of the roof and the large size of the items carried, users often need to use a ladder to place large or heavy items on the platform, a cumbersome and inconvenient process that significantly increases the difficulty of using the platform and raises safety risks. Utility Model Content

[0003] In view of this, the present invention proposes a slide rail structure and a vehicle-mounted slide rail platform, aiming to solve the problem that existing vehicle-mounted platforms are difficult to turn.

[0004] In a first aspect, this utility model proposes a slide rail structure, including a strip-shaped inner rail and an outer rail. The outer rail is provided with a groove, and the inner rail is disposed within the groove and can slide back and forth along the groove. The rear end of the outer rail is provided with a cylinder and a three-sided opening structure that is open at the top, bottom, and rear. The cylinder is located within the three-sided opening structure, and the left and right ends of the cylinder are respectively connected to the left and right walls of the outer rail. The cylinder can rotate around its axis. The front end of the inner rail is provided with a steering device, which includes a front column, a rear column, a left rod, a right rod, a steering rod, and a sliding shaft. The front column passes through a through hole at the front end of the steering rod, and the steering rod can rotate around... The front column rotates, with its left end connected to the front end of the left rod and its right end connected to the front end of the right rod. The steering rod is provided with a first through groove, and the sliding shaft passes through the first through groove and can slide along the first through groove. The left end of the sliding shaft is connected to the front end of the left wall of the inner rail, and its right end is connected to the front end of the right wall of the inner rail. The left end of the rear column passes through a through hole in the middle of the left wall of the inner rail and is connected to the rear end of the left rod. The right end of the rear column passes through a through hole in the middle of the right wall of the inner rail and is connected to the rear end of the right rod. The front column, the left rod, the rear column, and the right rod are connected end to end in sequence to form a rectangular frame structure.

[0005] When the inner rail slides backward along the groove until it contacts the cylinder in the area corresponding to the rear column on the lower wall of the inner rail, and the inner rail rotates around the cylinder, the rotating inner rail drives the sliding shaft to slide along the first through groove from one end of the first through groove to the other end. At the same time, the steering rod rotates upward around the front column until it intersects with the inner rail.

[0006] In one possible implementation, the steering device further includes a first roller and a second roller, with the front column passing through the central through hole of the first roller and the central through hole of the second roller respectively. Both the first roller and the second roller can rotate around the front column. When the inner rail slides back and forth along the slide groove, the front column contacts the bottom of the slide groove through the first roller and the second roller respectively.

[0007] In one possible implementation, the front end of the steering rod is located between the first roller and the second roller.

[0008] In one possible implementation, the steering device further includes a third roller and a fourth roller, with the rear column passing through the central through-holes of the third roller and the fourth roller, respectively. Both the third roller and the fourth roller can rotate around the rear column. Through-holes are provided in the lower wall of the inner rail in areas corresponding to the third roller and the fourth roller, with the third roller and the fourth roller extending out of the through-holes. When the inner rail slides back and forth along the slide groove, the rear column contacts the bottom of the slide groove through the third roller and the fourth roller, respectively.

[0009] In one possible implementation, a second through slot for the steering rod to extend is provided on the upper wall of the inner rail in the area corresponding to the steering rod, and / or a third through slot for the steering rod to extend is provided on the lower wall of the inner rail in the area corresponding to the steering rod.

[0010] In one possible implementation, the rear end of the outer rail is further provided with a fifth roller and a sixth roller, the cylinder passing through the central through hole of the fifth roller and the central through hole of the sixth roller respectively, and the cylinder contacting the lower wall of the inner rail through the fifth roller and the sixth roller respectively.

[0011] In one possible implementation, a locking device is provided at the rear end of the inner rail. The locking device includes a pawl, a spring, and a base. The front end of the pawl has an inclined structure. The upper end of the base is connected to the lower wall of the inner rail. A connecting post is provided at the front end of the base. The base is connected to the pawl through the connecting post, and the pawl can rotate around the connecting post. One end of the spring is connected to the inner rail, and the other end of the spring is connected to the pawl.

[0012] When the inner rail slides forward along the groove until the hook contacts the cylinder and continues to slide forward, the cylinder presses against the inclined structure to allow the hook to rotate around the connecting column and lift up, while the spring deforms. If the cylinder is completely squeezed into the lifted hook, the cylinder separates from the inclined structure, the spring drives the hook to rotate around the connecting column and fall to the position where the hook catches the cylinder, and the spring returns to its original position.

[0013] In one possible implementation, the locking device further includes a handle integrally formed with the hook, the handle being located above the hook, and a fourth through groove being provided on the upper wall of the inner rail, the handle extending out of the fourth through groove and movable relative to the fourth through groove.

[0014] In one possible implementation, the locking device further includes a crossbeam, the left and right ends of which are connected to the left and right walls of the inner rail, respectively, and the crossbeam is located below the spring.

[0015] Secondly, this utility model proposes a vehicle-mounted slide rail platform, including at least one connecting rod and two slide rail structures as described in the first aspect, wherein the two slide rail structures are parallel to each other and connected by the connecting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The vehicle-mounted slide rail platform includes at least one connecting rod and two slide rail structures, which are parallel to each other and connected by the connecting rod. The outer rail of the slide rail structure is provided with a groove, and the inner rail is embedded in the groove and can slide back and forth along the groove. A steering device is provided at the front end of the inner rail, which can slide back and forth along the groove with the inner rail. The steering device includes a front column, a rear column, a left rod, a right rod, a steering rod, and a sliding shaft. The front column, left rod, rear column, and right rod are connected end to end to form a rectangular frame structure. The sliding shaft is connected to the inner rail. The steering rod can rotate around the front column, and the sliding shaft can slide in the first through groove of the steering rod. This multi-degree-of-freedom rotation and sliding mechanism allows the inner rail to not only slide back and forth but also rotate relative to the outer rail, thereby completing the steering action of the slide rail structure. The outer rail has a cylindrical structure and a three-sided opening at its rear end. When the inner rail slides, the area on the lower wall of the inner rail corresponding to the rear column slides into the three-sided opening structure and contacts the cylinder. As the inner rail rotates around the cylinder, the rotating inner rail drives the sliding shaft to slide along the first through groove. Simultaneously, the steering rod rotates upward around the front column, thus switching the inner rail from a horizontal state during forward and backward sliding to a state where it intersects with the steering rod during steering. After steering, the steering rod, inner rail, and outer rail form a stable triangular structure, further enhancing the stability and overall rigidity of the slide rail structure during steering. This linkage mechanism of the slide rail structure ensures the coordinated movement of each component during steering, effectively preventing structural loosening or instability. Therefore, the vehicle-mounted slide rail platform using this structure, through the sliding cooperation between the inner and outer rails and the rotational linkage of the steering device, overcomes the limitations of traditional rigid straight rod platforms that are difficult to steer, achieving flexible adjustment and stable steering of the vehicle-mounted platform, significantly improving user convenience and experience.

[0030] Please refer to Figure 1-7 As shown, this utility model proposes a slide rail structure, including a strip-shaped inner rail 10 and an outer rail 20. The outer rail 20 is provided with a sliding groove 22, and the inner rail 10 is disposed within the sliding groove 22 and can slide back and forth along the sliding groove 22. The rear end of the outer rail 20 is provided with a cylinder 21 and a three-sided opening structure that is open at the top, bottom, and rear end. The cylinder 21 is located within the three-sided opening structure. The left and right ends of the cylinder 21 are respectively connected to the left and right walls of the outer rail 20, and the cylinder 21 can rotate around its axis. The front end of the inner rail 10 is provided with a steering device 30, which includes a front column 31, a rear column 32, a left rod 33, a right rod 34, a steering rod 35, and a sliding shaft 37. The front column 31 passes through a through hole at the front end of the steering rod 35, and the steering rod 35 can rotate around its axis. The front column 31 rotates, with its left end connected to the front end of the left rod 33 and its right end connected to the front end of the right rod 34. The steering rod 35 is provided with a first through groove 36, and the sliding shaft 37 passes through the first through groove 36 and can slide along the first through groove 36. The left end of the sliding shaft 37 is connected to the front end of the left wall of the inner rail 10, and the right end of the sliding shaft 37 is connected to the front end of the right wall of the inner rail 10. The left end of the rear column 32 passes through the through hole in the middle of the left wall of the inner rail 10 and is connected to the rear end of the left rod 33. The right end of the rear column 32 passes through the through hole in the middle of the right wall of the inner rail 10 and is connected to the rear end of the right rod 34. The front column 31, the left rod 33, the rear column 32, and the right rod 34 are connected end to end to form a rectangular frame structure.

[0031] When the inner rail 10 slides backward along the groove 22 until it contacts the cylinder 21 in the area of ​​the lower wall of the inner rail 10 corresponding to the rear column 32, and the inner rail 10 rotates around the cylinder 21, the rotating inner rail 10 drives the sliding shaft 37 to slide along the first through groove 36 from one end of the first through groove 36 to the other end. At the same time, the steering rod 35 rotates upward around the front column 31 until it intersects with the inner rail 10.

[0032] Specifically, the inner rail 10 is equipped with a steering device 30 at its front end. To improve the overall stability of the slide rail structure, a plug device can be installed at the front end of the outer rail 20 to block the front end of the outer rail 20, preventing the steering device 30 from accidentally sliding out when the inner rail 10 slides forward along the slide groove 22, thus ensuring that all components work together safely and reliably. The outer rail 20 can be designed as a fully open structure at the top, or it can be a structure with a closed front end and an open rear end. In addition, the open area of ​​the three-sided open structure should be designed to be sufficiently spacious to allow space for the inner rail 10 to rotate around the cylinder 21 and the steering rod 35 to rotate around the front column 31, ensuring smooth steering of the slide rail structure.

[0033] Compared with the prior art, the slide rail structure proposed in this embodiment includes an inner rail 10 and an outer rail 20. The outer rail 20 is provided with a sliding groove 22, and the inner rail 10 is embedded in the sliding groove 22 and can slide back and forth along the sliding groove 22. A steering device 30 is provided at the front end of the inner rail 10. The steering device 30 can slide back and forth along the sliding groove 22 together with the inner rail 10. It includes a front column 31, a rear column 32, a left rod 33, a right rod 34, a steering rod 35, and a sliding shaft 37. The front column 31, left rod 33, rear column 32, and right rod 34 are connected end to end to form a rectangular frame structure. The sliding shaft 37 is connected to the inner rail 10. The steering rod 35 can rotate around the front column 31, and the sliding shaft 37 can slide within the first through groove 36 of the steering rod 35. This multi-degree-of-freedom rotation and sliding mechanism allows the inner rail 10 to not only slide back and forth, but also rotate relative to the outer rail 20, thereby completing the steering action of the slide rail structure. The outer rail 20 has a cylinder 21 and a three-sided opening structure at its rear end. When the inner rail 10 slides, causing the area on its lower wall corresponding to the rear column 32 to slide into the three-sided opening structure and contact the cylinder 21, and the inner rail 10 rotates around the cylinder 21, the rotating inner rail 10 will drive the sliding shaft 37 to slide along the first through groove 36. At the same time, the steering rod 35 will rotate upward around the front column 31, thus switching the inner rail 10 from a horizontal state during forward and backward sliding to a state intersecting with the steering rod 35 during turning. After turning, the steering rod 35, the inner rail 10, and the outer rail 20 form a stable triangular structure, which can further enhance the stability and overall rigidity of the slide rail structure during turning. The linkage mechanism of this slide rail structure ensures the coordinated movement of each component during turning, effectively preventing structural loosening or instability. It is evident that the vehicle-mounted sliding rail platform using this sliding rail structure overcomes the limitation of traditional rigid straight rod platforms being difficult to steer by the sliding cooperation between the inner rail 10 and the outer rail 20 in the sliding rail structure and the rotation linkage of the steering device 30. This enables flexible adjustment and stable steering of the vehicle-mounted platform, significantly improving the user's convenience and experience.

[0034] In some embodiments of this application, the steering device 30 further includes a first roller 41 and a second roller 42, the front column 31 passing through the central through hole of the first roller 41 and the central through hole of the second roller 42 respectively, and both the first roller 41 and the second roller 42 can rotate around the front column 31; when the inner rail 10 slides back and forth along the slide groove 22, the front column 31 contacts the bottom of the slide groove 22 through the first roller 41 and the second roller 42 respectively.

[0035] Specifically, when the inner rail 10 slides back and forth along the slide groove 22, both the first roller 41 and the second roller 42 maintain close contact with the bottom of the slide groove 22, forming a stable rolling support. This design not only effectively reduces the sliding friction between the inner rail 10 and the slide groove 22, but also significantly reduces the wear and noise caused by the friction between the two, thereby ensuring that the sliding of the inner rail 10 is smoother and more stable.

[0036] In some embodiments of this application, the front end of the steering rod 35 is located at the middle position between the first roller 41 and the second roller 42.

[0037] Specifically, the aforementioned arrangement of the steering rod 35 ensures more even force distribution, effectively preventing it from wobbling or shifting due to uneven force distribution during the sliding of the inner rail 10. Since the steering rod 35 only rotates when the inner rail 10 turns relative to the outer rail 20 and remains horizontal under normal conditions, its rear end can contact and be positioned above the rear pillar 32. The rear pillar 32 provides additional support to the steering rod 35, preventing it from sagging and thus ensuring smooth sliding of the inner rail 10 without interfering with its normal forward and backward movement.

[0038] In some embodiments of this application, the steering device 30 further includes a third roller 43 and a fourth roller 44. The rear column 32 passes through the central through hole of the third roller 43 and the central through hole of the fourth roller 44, respectively. Both the third roller 43 and the fourth roller 44 can rotate around the rear column 32. Through holes are provided in the lower wall of the inner rail 10 in the areas corresponding to the third roller 43 and the fourth roller 44, and the third roller 43 and the fourth roller 44 extend out of the through holes. When the inner rail 10 slides back and forth along the slide groove 22, the rear column 32 contacts the bottom of the slide groove 22 through the third roller 43 and the fourth roller 44, respectively.

[0039] Specifically, the functions of the third roller 43 and the fourth roller 44 are similar to those of the first roller 41 and the second roller 42, and will not be repeated here. It should be noted that the distance between the third roller 43 and the fourth roller 44 is smaller than the distance between the first roller 41 and the second roller 42, so that the area on the lower wall of the inner rail 10 corresponding to the rear column 32 can better contact the cylinder 21. Generally, the third roller 43 and the fourth roller 44 are positioned at the center of the lower wall of the inner rail 10, while the areas on the lower wall of the inner rail 10 that contact the cylinder 21 are located on both sides of the lower wall of the inner rail 10.

[0040] In some embodiments of this application, a second through groove 11 for the steering rod 35 to extend is provided on the upper wall of the inner rail 10 in the area corresponding to the steering rod 35, and / or a third through groove for the steering rod 35 to extend is provided on the lower wall of the inner rail 10 in the area corresponding to the steering rod 35.

[0041] Specifically, by providing through slots on the upper and / or lower walls of the inner rail 10 to facilitate the extension of the steering rod 35, excessive interference between the steering rod 35 and the internal structure of the inner rail 10 can be avoided. Furthermore, if through slots are provided on both the upper and lower walls of the inner rail 10, this double-slot design can also provide effective vertical restraint for the steering rod 35, further reducing the possibility of it swaying and shaking during the sliding process of the inner rail 10, and improving the overall stability of the slide rail structure.

[0042] In some embodiments of this application, the rear end of the outer rail 20 is further provided with a fifth roller and a sixth roller, the cylinder 21 passes through the central through hole of the fifth roller and the central through hole of the sixth roller respectively, and the cylinder 21 contacts the lower wall of the inner rail 10 through the fifth roller and the sixth roller respectively.

[0043] Specifically, the functions of the fifth and sixth rollers are similar to those of the first roller 41 and the second roller 42, and will not be repeated here. It should be noted that, in addition to allowing the inner rail 10 to rotate around it, the cylinder 21 can also be used to lock in conjunction with the locking device 50. When the locking device 50 locks the cylinder 21, the relative movement between the outer rail 20 and the inner rail 10 is restricted, effectively preventing accidental displacement and ensuring the safety of the slide rail structure. The concentric support of the double rollers further stabilizes the radial position of the cylinder 21, preventing it from wobbling or shifting during rotation, ensuring precise engagement with the locking device 50, and thus improving the reliability and durability of the locking effect.

[0044] In some embodiments of this application, a locking device 50 is provided at the rear end of the inner rail 10. The locking device 50 includes a hook 51, a spring 53, and a base 54. The front end of the hook 51 is provided with an inclined structure. The upper end of the base 54 is connected to the lower wall of the inner rail 10. A connecting post 55 is provided at the front end of the base 54. The base 54 is connected to the hook 51 through the connecting post 55, and the hook 51 can rotate around the connecting post 55. One end of the spring 53 is connected to the inner rail 10, and the other end of the spring 53 is connected to the hook 51.

[0045] When the inner rail 10 slides forward along the groove 22 until the hook 51 contacts the cylinder 21 and continues to slide forward, the cylinder 21 presses against the inclined structure so that the hook 51 rotates around the connecting post 55 and is lifted up, while the spring 53 deforms; if the cylinder 21 is completely squeezed into the lifted hook 51, the cylinder 21 separates from the inclined structure, the spring 53 drives the hook 51 to rotate around the connecting post 55 and fall to the position where the hook 51 locks the cylinder 21, and the spring 53 returns to its original position.

[0046] Specifically, please refer to Figure 6 As shown, the locking device 50 can slide back and forth along the slide groove 22 along the inner rail 10. When the inner rail 10 continues to slide forward along the slide groove 22, once the hook 51 contacts the cylinder 21, the cylinder 21 will contact the inclined structure at the front end of the hook 51 and continuously perform a squeezing action along the inclined surface of the inclined structure, so as to push the hook 51 to rotate around the connecting post 55 and lift it up through squeezing, while driving the spring 53 to deform and store elastic potential energy. As the inner rail 10 moves further forward, the cylinder 21 will be completely squeezed into the interior of the lifted hook-shaped hook 51, the cylinder 21 will separate from the inclined structure, the spring 53 will quickly reset and drive the hook 51 to rotate around the connecting post 55 and fall down, thereby locking the cylinder 21 and realizing the locking between the inner rail 10 and the outer rail 20. The locking device 50 is simple and reliable in design. Through the mechanical cooperation between the hook 51 and the cylinder 21, combined with the restoring force of the spring 53, it can realize the automatic locking between the inner rail 10 and the outer rail 20, effectively preventing the slide rail structure from being accidentally displaced. It is particularly suitable for vehicle-mounted slide rail platform application scenarios that require frequent locking and unlocking.

[0047] In some embodiments of this application, the locking device 50 further includes a handle 52 integrally formed with the hook 51, the handle 52 being located above the hook 51, and a fourth through groove 12 being provided on the upper wall of the inner rail 10, the handle 52 extending out of the fourth through groove 12 and being movable relative to the fourth through groove 12.

[0048] Specifically, the handle 52 and the hook 51 are integrally formed and extend beyond the upper wall of the inner rail 10, designed to facilitate manual operation by the user. When the inner rail 10 needs to slide, the user can turn the handle 52 to rotate the hook 51 around the connecting post 55, causing the hook 51 to lift and release the stuck cylinder 21, thereby releasing the locked state of the inner rail 10. The inner rail 10 can then slide freely back and forth along the slide groove 22 of the outer rail 20. The handle 52 extends out of the fourth through groove 12 provided on the upper wall of the inner rail 10, making it easy for the user to directly grip and apply force, improving the convenience of unlocking.

[0049] In some embodiments of this application, the locking device 50 further includes a crossbeam 56, the left end and the right end of which are connected to the left wall and the right wall of the inner rail 10, respectively, and the crossbeam 56 is located below the spring 53.

[0050] Specifically, the crossbeam 56 is located below the spring 53, effectively preventing the spring 53 from interfering with or contacting other components within the inner rail 10 during operation, ensuring that the normal deformation and reset function of the spring 53 are not affected. Through the effective isolation provided by the crossbeam 56, damage to the spring 53 or locking failure due to component interference can be avoided, ensuring the stable operation of the slide rail structure.

[0051] The following are embodiments of the vehicle-mounted slide rail platform provided by this utility model. The embodiments of the vehicle-mounted slide rail platform belong to the same concept as the embodiments of the slide rail structure described above. Details not fully described in the embodiments of the vehicle-mounted slide rail platform can be found in the embodiments of the slide rail structure described above.

[0052] This utility model proposes a vehicle-mounted slide rail platform, including at least one connecting rod 60 and two slide rail structures as described above, wherein the two slide rail structures are parallel to each other and connected by the connecting rod 60.

[0053] Specifically, when the vehicle-mounted slide rail platform includes a connecting rod 60 and two synchronously moving slide rail structures, the entire vehicle-mounted slide rail platform has an I-beam-like frame structure. Please refer to [reference needed]. Figure 8 As shown, when the vehicle-mounted slide rail platform uses two synchronously moving slide rail structures and two parallel connecting rods 60, the connecting rods 60 and the slide rail structures are connected in sequence to form a grid-like frame structure. This grid-like frame structure is simple and stable in design, effectively improving the overall rigidity of the vehicle-mounted slide rail platform, ensuring that the platform remains parallel and is not easily deformed during use, meeting the requirements of high load-bearing and frequent adjustment in vehicle applications. The luggage compartment can be directly fixed to the inner rail 10 or to the connecting rod 60. If fixed to the connecting rod 60, the connecting rod 60 must be able to move with the inner rail 10. After the vehicle-mounted sliding rail platform is installed on the roof, users can retrieve and place luggage without the need for a ladder. They simply pull the inner rails 10 of the two sliding rail structures to make them slide synchronously. When the inner rail 10 slides to the predetermined position (i.e., the area on the lower wall of the inner rail 10 corresponding to the rear pillar 32 slides into the three-sided opening structure of the outer rail 20 and contacts the cylinder 21), the inner rail 10 can be turned relative to the outer rail 20, thus smoothly moving the inner rail 10 from the roof position to the side of the vehicle. Whether fixing the luggage to the inner rail 10 or removing the luggage from the inner rail 10, the user can operate directly from the ground, greatly facilitating the use of the vehicle-mounted sliding rail platform and improving the convenience and safety of operation.

[0054] Compared with existing technologies, the vehicle-mounted sliding rail platform proposed in this embodiment includes at least one connecting rod 60 and two sliding rail structures. The two parallel sliding rail structures are connected by the connecting rod 60, enabling synchronous sliding and supporting the steering function of the inner rail 10 relative to the outer rail 20. This facilitates smooth switching of the inner rail 10 from the roof position to the side of the vehicle, greatly improving the convenience and comfort of loading and unloading luggage from the inner rail 10. Furthermore, combined with a rationally designed locking device 50, the vehicle-mounted sliding rail platform can achieve quick and reliable locking and releasing, ensuring safety.
