[0005] When the inner rail slides backward along the sliding groove to the area of the lower wall of the inner rail corresponding to the rear column and contacts the cylinder, 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 to the other end of the first through groove. At the same time, the steering rod rotates upward around the front column to a state of intersecting with the inner rail.

[0017] Compared to the prior art, the present invention offers the following advantages: the vehicle-mounted slide rail bracket comprises a connecting rod for connecting to a bicycle frame, a support rod for supporting a bicycle wheel, and two slide rail structures. The two slide rail structures are connected by the connecting rod and the support rod. Both the connecting rod and the support rod move synchronously with the movement of the slide rail structures. The outer rail of the slide rail structure is provided with a slide groove, into which the inner rail fits and can slide back and forth. A steering device is provided at the front end of the inner rail, which can slide back and forth along the slide groove along with the inner rail. The steering device comprises a front post, a rear post, a left post, a right post, a steering rod, and a sliding shaft. The front post, left post, rear post, and right post are connected end to end to form a rectangular frame structure. The sliding shaft connects the inner rail. The steering rod can rotate about the front post, while the sliding shaft can slide within the first through-slot of the steering rod. This multi-degree-of-freedom rotation and sliding mechanism enables 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 rear end of the outer rail is provided with a cylinder and a three-sided opening structure. When the inner rail slides so that the area in the lower wall of the inner rail corresponding to the rear column slides into the three-sided opening structure and contacts the cylinder, and the inner rail rotates around the cylinder, the rotating inner rail will drive the sliding shaft to slide along the first through groove, and at the same time the steering rod will rotate upward around the front column, so that the inner rail switches from a horizontal state when sliding back and forth to a state intersecting with the steering rod when turning. After turning, the steering rod, the inner rail and the outer rail form a stable triangular structure, which can further enhance the stability and overall rigidity of the slide rail structure in the turning state. The linkage mechanism of the slide rail structure ensures the coordinated movement of various components during turning, and can effectively prevent the occurrence of loose or unstable structure. It can be seen that the vehicle-mounted slide rail bracket using this slide rail structure, through the sliding cooperation of the inner rail and the outer rail in the slide rail structure and the rotation linkage of the steering device, breaks through the limitation of the traditional rigid straight rod platform that is difficult to turn, and realizes the flexible adjustment and stable steering of the vehicle-mounted platform. Since the steering of the inner rail will drive the connecting rod and the support rod to turn synchronously, the bicycle installed on it can also turn accordingly, thereby improving the flexibility and convenience of loading and unloading the bicycle on the vehicle-mounted sliding rail bracket, and greatly optimizing the user experience.

[0033] Please refer to Figure 1-7 As shown, the present invention 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 slide groove 22, the inner rail 10 is arranged in the slide groove 22 and can slide back and forth along the slide 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 in the three-sided opening structure, the left end and the right end of the cylinder 21 are respectively connected to the left wall and the right wall of the outer rail 20, and the cylinder 21 can rotate around the axis of the cylinder 21; the front end of the inner rail 10 is provided with a steering device 30, the steering device 30 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 the through hole at the front end of the steering rod 35, and the steering rod 35 can rotate around the axis of the The front column 31 rotates, the left end of the front column 31 is connected to the front end of the left rod 33, the right end of the front column 31 is connected to the front end of the right rod 34, the steering rod 35 is provided with a first through slot 36, the sliding shaft 37 is passed through the first through slot 36, and the sliding shaft 37 can slide along the first through slot 36, the left end of the sliding shaft 37 is connected to the front end of the left wall of the inner rail 10, 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 in sequence to form a rectangular frame structure;

[0034] When the inner rail 10 slides backward along the slide groove 22 to the area on the lower wall of the inner rail 10 corresponding to the rear column 32 and contacts the cylinder 21, 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 to the other end of the first through groove 36. At the same time, the steering rod 35 rotates upward around the front column 31 to a state of intersecting with the inner rail 10.

[0035] Specifically, a steering device 30 is provided at the front end of the inner rail 10. In order to improve the overall stability of the slide rail structure, a plugging device can be provided at the front end of the outer rail 20 to block the front end of the outer rail 20, thereby preventing the steering device 30 from accidentally sliding out when the inner rail 10 slides forward along the slide groove 22, thereby ensuring that all components work together safely and reliably. The outer rail 20 can be designed as a fully open top structure, or it can be designed to have a closed top front end and an open rear end. In addition, the open area of the three-sided opening structure should be designed to be spacious enough to reserve the space required for the inner rail 10 to rotate around the cylinder 21 and the steering rod 35 to rotate around the front column 31, thereby ensuring smooth steering of the slide rail structure.

[0036] Compared to 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 slide groove 22, into which the inner rail 10 is inserted and can slide back and forth along the slide groove 22. A steering device 30 is provided at the front end of the inner rail 10. This steering device 30 can slide back and forth along the slide groove 22 along with the inner rail 10. The steering device 30 comprises a front post 31, a rear post 32, a left rod 33, a right rod 34, a steering rod 35, and a sliding shaft 37. The front post 31, left rod 33, rear post 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 about the front post 31, while the sliding shaft 37 can slide within the first through slot 36 of the steering rod 35. This multi-degree-of-freedom rotation and sliding mechanism enables 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 rear end of the outer rail 20 is provided with a cylinder 21 and a three-sided opening structure. When the inner rail 10 slides, the area of the lower wall of the inner rail 10 corresponding to the rear column 32 slides into the three-sided opening structure and contacts the cylinder 21. When 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-slot 36. At the same time, the steering rod 35 rotates upward around the front column 31, thereby switching the inner rail 10 from a horizontal state during forward and backward sliding to a state intersecting with the steering rod 35 during steering. After steering, the steering rod 35, inner rail 10, and outer rail 20 form a stable triangular structure, which can further enhance the stability and overall rigidity of the slide rail structure during steering. The linkage mechanism of the slide rail structure ensures the coordinated movement of various components during steering, which can effectively prevent the occurrence of structural loosening or instability. As can be seen, the vehicle-mounted slide rail bracket utilizing this slide rail structure overcomes the difficulty of steering a conventional rigid straight-rod platform through the sliding fit of the inner rail 10 and outer rail 20 within the slide rail structure, and the rotational linkage of the steering device 30, thereby enabling flexible adjustment and stable steering of the vehicle-mounted platform. Since the steering of the inner rail 10 simultaneously drives the connecting rod 60 and support rod 72 to steer, the bicycle mounted thereon can also steer accordingly, thereby enhancing the flexibility and convenience of loading and unloading the bicycle from the vehicle-mounted slide rail bracket and greatly improving the user experience.

[0037] In some embodiments of the present application, the steering device 30 also includes a first roller 41 and a second roller 42, and the front column 31 passes through the central through hole of the first roller 41 and the central through hole of the second roller 42 respectively, and the first roller 41 and the second roller 42 can both 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.

[0038] Specifically, as the inner rail 10 slides back and forth along the chute 22, both the first roller 41 and the second roller 42 maintain close contact with the bottom of the chute 22, forming a stable rolling support. This design not only effectively reduces the sliding friction between the inner rail 10 and the chute 22, but also significantly reduces the wear and noise caused by the friction between the two, thereby ensuring smoother and more stable sliding of the inner rail 10.

[0039] In some embodiments of the present application, the front end of the steering rod 35 is located in the middle of the first roller 41 and the second roller 42 .

[0040] Specifically, the aforementioned arrangement of the steering rod 35 provides a more even force distribution to the steering rod 35, effectively preventing it from shaking or deflecting due to uneven force distribution during the sliding of the inner rail 10. Since the steering rod 35 rotates only when the inner rail 10 turns and remains horizontal at other times, its rear end can contact and lie above the rear post 32, providing additional support for the steering rod 35 and preventing it from sagging. This prevents it from interfering with the normal forward and backward sliding of the inner rail 10, ensuring a smooth sliding process.

[0041] In some embodiments of the present application, the steering device 30 also includes a third roller 43 and a fourth roller 44, and 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. The third roller 43 and the fourth roller 44 can both rotate around the rear column 32, and through holes are set in the areas corresponding to the third roller 43 and the fourth roller 44 in the lower wall of the inner rail 10, 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.

[0042] Specifically, the functions of the third and fourth rollers 43, 44 are similar to those of the first and second rollers 41, 42 and will not be further described here. It should be noted that the spacing between the third and fourth rollers 43, 44 is smaller than that between the first and second rollers 41, 42, to facilitate better contact between the area of the lower wall of the inner rail 10 corresponding to the rear post 32 and the cylinder 21. Generally speaking, the third and fourth rollers 43, 44 are located in the middle of the lower wall of the inner rail 10, while the areas of the lower wall of the inner rail 10 that contact the cylinder 21 are located on both sides of the lower wall.

[0043] In some embodiments of the present application, a second through groove 11 for the steering rod 35 to extend is provided in an area of the upper wall of the inner rail 10 corresponding to the steering rod 35, and / or a third through groove for the steering rod 35 to extend is provided in an area of the lower wall of the inner rail 10 corresponding to the steering rod 35.

[0044] 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, it is possible to prevent excessive interference between the steering rod 35 and the internal structure of the inner rail 10. In addition, if through slots are provided on the upper and lower walls of the inner rail 10, this dual through slot design can also effectively limit the steering rod 35 in the vertical direction, further reducing the possibility of its swinging and shaking during the sliding process of the inner rail 10, thereby improving the overall stability of the slide rail structure.

[0045] In some embodiments of the present application, the rear end of the outer rail 20 is further provided with a fifth roller and a sixth roller, and 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.

[0046] Specifically, the functions of the fifth and sixth rollers are similar to those of the first and second rollers 41 and 42, and will not be further described 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 cooperate with the locking device 50 for locking; when the locking device 50 locks the cylinder 21, the relative movement between the outer rail 20 and the inner rail 10 will be restricted, thereby effectively preventing the accidental displacement of the two and ensuring the safety of the slide rail structure. The concentric support of the double rollers can further stabilize the radial position of the cylinder 21, preventing it from shaking or shifting during rotation, so as to ensure precise cooperation with the locking device 50, thereby improving the reliability and durability of the locking effect.

[0047] In some embodiments of the present 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 column 55 is provided at the front end of the base 54. The base 54 is connected to the hook 51 through the connecting column 55, and the hook 51 can rotate around the connecting column 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.

[0048] When the inner rail 10 slides forward along the slide groove 22 until the hook 51 contacts the cylinder 21 and continues to slide forward, the cylinder 21 squeezes the inclined structure so that the hook 51 rotates around the connecting column 55 and rises, and the spring 53 is deformed at the same time; if the cylinder 21 is completely squeezed into the raised hook 51, the cylinder 21 is separated from the inclined structure, and the spring 53 drives the hook 51 to rotate around the connecting column 55 and fall to the position where the hook 51 is stuck to the cylinder 21, and the spring 53 is reset.

[0049] For details, please refer to Figure 6 As shown, the locking device 50 can slide forward and backward along the slide groove 22 along with 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 surface structure at the front end of the hook 51 and continue to squeeze along the inclined surface of the inclined surface structure, so as to push the hook 51 to rotate and lift around the connecting column 55 through squeezing, while at the same time causing the spring 53 to deform and store elastic potential energy. As the inner rail 10 moves further forward, the cylinder 21 will completely squeeze into the interior of the raised curved hook 51, and the cylinder 21 will separate from the inclined surface structure. The spring 53 will quickly reset and drive the hook 51 to rotate and fall around the connecting column 55, thereby locking the cylinder 21 and achieving 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 reset force of the spring 53, it can achieve automatic locking between the inner rail 10 and the outer rail 20, effectively preventing the slide rail structure from accidentally shifting. It is particularly suitable for vehicle-mounted slide rail bracket application scenarios that require frequent locking and unlocking.

[0050] In some embodiments of the present application, the locking device 50 also includes a handle 52 integrally formed with the hook 51, the handle 52 is located above the hook 51, and a fourth through slot 12 is provided on the upper wall of the inner rail 10, and the handle 52 extends out of the fourth through slot 12 and can move relative to the fourth through slot 12.

[0051] Specifically, the handle 52 is integrally formed with the hook 51 and extends from the upper wall of the inner rail 10, facilitating manual operation. When the inner rail 10 needs to slide, the user pulls the handle 52, causing the hook 51 to rotate around the connecting post 55. This lifts the hook 51 and releases the trapped cylinder 21, thereby unlocking the inner rail 10 and allowing it to slide freely forward and backward along the slide groove 22 of the outer rail 20. The handle 52 extends from the fourth through-slot 12 on the upper wall of the inner rail 10, allowing the user to directly grasp and apply force, enhancing the ease of unlocking.

[0052] In some embodiments of the present application, the locking device 50 further includes a crossbeam 56 , the left and right ends of which are respectively connected to the left and right walls of the inner rail 10 , and the crossbeam 56 is located below the spring 53 .

[0053] 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. The effective isolation of the crossbeam 56 prevents damage to the spring 53 or locking failure caused by component interference, ensuring the stable operation of the slide rail structure.

[0054] The following is an embodiment of the vehicle-mounted slide rail bracket provided by the present invention. The embodiment of the vehicle-mounted slide rail bracket and the embodiment of the slide rail structure above are of the same concept. For details not described in detail in the embodiment of the vehicle-mounted slide rail bracket, reference can be made to the embodiment of the slide rail structure above.

[0055] Please refer to Figure 8-10 As shown, the present invention proposes a vehicle-mounted slide rail bracket, comprising a connecting rod 60 for connecting a bicycle frame, a support rod 72 for supporting a bicycle wheel, and two slide rail structures as described above, wherein the two slide rail structures are parallel to each other and are connected by the connecting rod 60 and the support rod 72, the connecting rod 60 is perpendicular to the two slide rail structures respectively, and the plane where the connecting rod 60 is located is coplanar with the plane where the slide rail structures are located; the support rod 72 is perpendicular to the two slide rail structures respectively, and the plane where the support rod 72 is located is perpendicular to the plane where the slide rail structures are located; the connecting rod 60 and the support rod 72 can both move synchronously with the movement of the inner rail 10.

[0056] Specifically, the connecting rod 60, the support rod 72 and the two slide rail structures are sequentially spliced to form a frame structure suitable for loading bicycles. The frame structure is simple and stable in design, which can effectively improve the overall rigidity of the vehicle-mounted slide rail bracket, ensure that the vehicle-mounted slide rail bracket remains parallel and not easily deformed during use, and meet the vehicle-mounted application requirements of carrying and frequently taking and placing bicycles. Since the vehicle-mounted slide rail bracket is installed on the roof, the two parallel and synchronously movable slide rail structures are arranged along the length of the roof, and the support rod 72 used to fix the bicycle wheel is not coplanar with the slide rail structure and is arranged vertically, that is, the support rod 72 is perpendicular to the plane of the roof. Therefore, the bicycle does not need to be upright, and can be fixed to the vehicle-mounted slide rail bracket in a lying state, that is, the bicycle is parallel to the plane of the roof. Compared to the traditional method of securing a bicycle upright on a vehicle roof (an upright bicycle poses a safety hazard during driving, potentially causing it to wobble or even fall off), this vehicle-mounted slide rail bracket effectively lowers the height of the bicycle's fixed center of gravity by arranging the support rod 72 perpendicularly to the slide rail structure, reducing wind resistance and the risk of wobble during driving. Furthermore, the horizontal installation method makes loading and unloading the bicycle more labor-saving, avoids high-altitude lifting, and improves operational safety and convenience. Furthermore, because relevant regulations stipulate that the height of items loaded on the roof cannot exceed 0.5 meters, this horizontal bicycle loading method can perfectly solve the problem of domestic height restrictions. After the vehicle-mounted sliding rail bracket is installed on the vehicle roof, users can access bicycles without the aid of a ladder by simply pulling the inner rails 10 of the two sliding rail structures to slide synchronously. Once the inner rails 10 slide to a predetermined position (i.e., the area of the lower wall of the inner rails 10 corresponding to the rear pillars 32 slides into the three-sided opening of the outer rails 20 and contacts the cylinders 21), the inner rails 10 can be rotated relative to the outer rails 20, thereby smoothly moving the inner rails 10 from the roof to the side of the vehicle body. The connecting rods 60 and support rods 72 move synchronously with the movement of the inner rails 10, and the bicycles attached to the connecting rods 60 and support rods 72 also move from the roof to the side of the vehicle body. Whether attaching or detaching a bicycle to the inner rails 10, users can do so directly from the ground, greatly facilitating the use of the vehicle-mounted sliding rail bracket and improving both ease and safety of operation.

[0057] In some embodiments of the present application, the vehicle-mounted slide rail bracket also includes an auxiliary rod 71 and two supporting piles 73. The auxiliary rod 71 and the connecting rod 73 are parallel to each other, and the auxiliary rod 71 is respectively connected to the two slide rail structures. The auxiliary rod 71 is also respectively connected to the support rod 72 through the two supporting piles 73.

[0058] Specifically, the connection method between the support rod 72 and the slide rail structure is only an exemplary structure in the present invention. In actual applications, other forms of connection methods can also be used, which will not be described here.

[0059] Compared with the prior art, the vehicle-mounted slide rail bracket proposed in this embodiment includes a connecting rod 60, a support rod 72 and two slide rail structures. The two parallel slide rail structures are connected by the connecting rod 60 and the support rod 72, and can move synchronously, supporting the sliding and steering functions of the inner rail 10 relative to the outer rail 20, making it convenient for users to smoothly switch the inner rail 10 from the roof position to the side position of the vehicle body, greatly improving the convenience and operating comfort of taking and placing bicycles from the inner rail 10. In addition, combined with a reasonably designed locking device 50, the vehicle-mounted slide rail bracket can also achieve fast and reliable locking and release to ensure safe use. The vehicle-mounted slide rail bracket has a stable structure, is easy to operate, and is safe and reliable. The slide rail structures are arranged in pairs, and the bottom of the outer rail 20 is fixed to the roof. The fixing methods are flexible and diverse, and screws, clips, suction cups and other methods can be used to ensure that the installation and fixing process is quick and convenient. An interface can also be set on the top of the inner rail 10 for installing various other expansion parts such as suitcases, luggage frames, kayak racks and ski racks, all of which support steering adjustment and convenient access to adapt to diverse vehicle loading needs.

[0060] It should be noted that the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

Any equivalent structural transformation made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields, is included in the scope of protection of the present invention.
