Description
Technical Field
[0001] This application relates to the field of bicycle rack technology, and in particular to a bicycle rack for a towable caravan. Background Technology
[0002] With the increasing popularity of self-driving travel and outdoor camping, towable caravans are becoming more and more popular due to their flexibility and comfort. Bicycle racks for towable caravans are specially designed accessories for mounting bicycles on the caravan.
[0003] Existing RV bicycle racks are generally fixed to the RV and cannot be moved. Users need to lift the bicycle to a high position to suspend it, which is difficult to install and remove and not easy for a single person to operate. Some existing RV racks use horizontal push-pull designs to overcome these problems, such as the RV bicycle rack disclosed in CN218594252U, which uses a guide rail assembly. When suspending the bicycle, you only need to slide out the sliding component to lower the height of the suspension assembly to the ground. There is no need to lift the bicycle to suspend it. You only need to push the bicycle onto the suspension assembly to secure it. However, due to the height of the U-shaped bottom crossbar, the suspension assembly may scrape the ground on different RVs, resulting in poor applicability. In addition, it is also difficult to restore the position of the suspension assembly.
[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application.
[0005] Lifting the bicycle to a high position to complete the suspension installation and removal is quite difficult, as shown in the patent number... Summary of the Invention

[0031] In the embodiments of this application, please refer to Figure 1-9As shown, this bicycle rack for a towable RV mainly includes: a trapezoidal fixing frame 1, used to fix it to the RV, including a U-shaped support plate 101 at its top, wherein a sliding component is provided inside the U-shaped support plate 101; a movable plate 2, fixed to the sliding component and capable of sliding on the sliding component; and an extension shelf, including a first horizontal plate 3, a second horizontal plate 4, and support frames 5, wherein the end of the first horizontal plate 3 is fixed to the center of the movable plate 2, and the two second horizontal plates 4 are respectively fixed to the two ends of the top of the first horizontal plate 3, and the support frames 5 are in groups of two, for a total of four groups. Each set is respectively set at the ends of the two second horizontal plates 4. The support frame 5 is used to place and support the bicycle. The vehicle fixing assembly includes a fixing rod 6, a mounting piece 7, a longitudinal rotating piece 8 and a fixing bend rod 9. The fixing rod 6 is fixed at the center of the top of the second horizontal plate 4. The mounting piece 7 is fixed on the fixing rod 6. The longitudinal rotating piece 8 is clamped and fixed on the mounting piece 7. The fixing bend rod 9 is slidably set on the longitudinal rotating piece 8. The fixing bend rod 9 fixes the bicycle placed on the support frame 5 by hooking the bicycle frame.
[0032] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.
[0033] like Figure 9 As shown, a U-shaped groove 10 is formed on the U-shaped support plate 101. The sliding assembly is disposed within the U-shaped groove 10. The sliding assembly includes a main slide rail 11, a top slide rail 12, a sliding member 13, and a rotating member 14. The main slide rail 11 is disposed on both sides of the U-shaped groove 10. The sliding member 13 slides within the U-shaped groove 10 via the main slide rail 11. The rotating member 14 rotates on the top of the sliding member 13. The top slide rail 12 is fixed to the rotating member 14. This assembly is used when the frame needs to be removed. When loading and unloading a bicycle, simply move the slider 13 horizontally on the main slide rail 11, and then slide the movable plate 2 on the top slide rail 12. Move the extended shelf and vehicle fixing components at the top of the movable plate 2 laterally and press down to deflect the rotating part 14. This will lower the height of the bicycle on the support frame 5, making it easier to unload. Due to the height limitation of the trapezoidal fixing frame 1 and the limitation of the deflection angle of the rotating part 14, it can be ensured that the rotating part 14 will not touch the ground after deflection and that the height it descends to is low enough, making it convenient for one person to load and unload the bicycle.
[0034] In addition, limit posts 25 are provided on both sides of the U-shaped support plate 101, and waist-shaped limit grooves 24 are provided at the ends of the movable plate 2. When the movable part does not deflect with the rotating part 14 and is parallel to the U-shaped support plate 101, the horizontally moving sliding part 13 will place the limit posts 25 in the limit grooves 24, thereby locking the movable plate 2 and preventing misoperation.
[0035] Furthermore, a limiting plate 26 is formed at the end of the sliding member 13 to limit the position of the sliding block. The limiting block 27 reaches the maximum sliding distance of the sliding block when it contacts the main slide rail 11 in the U-shaped groove 10. In addition, a limiting block 27 is provided at the top of the rotating member 14 to limit the sliding range of the movable plate 2.
[0036] like Figure 8 As shown, the movable plate 2 slides on the rotating member 14 via the top slide rail 12. Several sets of tension springs 15 are provided between the movable plate 2 and the sliding member 13. When the movable plate 2 partially slides away from the rotating member 14, the tension springs 15 are stretched and continuously provide a restoring force to the movable plate 2. After the bicycle is removed, simply support the fixing rod 6 and slowly and easily push the movable plate 2 and its extended shelf and vehicle fixing components back onto the rotating member 14, so that the center of gravity returns to the rotating member 14, and the rotating member 14 can return to the U-shaped groove 10. The operation is simple and convenient, and a single person can easily complete the disassembly and assembly.
[0037] Specifically, the ends of the movable plate 2 and the sliding member 13 are respectively formed with mounting plates 16, and the mounting plates 16 are provided with a plurality of mounting holes 17. The two ends of the tension spring 15 are respectively fixed in the mounting holes 17 on the two mounting plates 16.
[0038] like Figure 1 As shown, the support frame 5 has a vertically extending positioning groove 18. Elastic plates 19 are provided on both sides of the positioning groove 18. The elastic plates 19 are inclined downwards at an angle of about 60 degrees. The positioning groove 18 is used to place the bicycle wheel, while the elastic plates 19 can prevent the edge of the positioning groove 18 from cutting the tire. The elastic plates 19 have a certain elasticity and can swing up and down within a certain range.
[0039] Furthermore, a clamping and fixing plate 20 is formed at the bottom of the first horizontal plate 3. The first horizontal plate 3 is welded to the movable plate 2 through the clamping and fixing plate 20. Specifically, the clamping and fixing plates 20 are arranged in pairs.
[0040] like Figure 4 As shown, to facilitate the installation of the horizontal plate, the top of the first horizontal plate 3 is provided with two slots 21 with inclined bottom surfaces, and the first horizontal plate 3 and the second horizontal plate 4 are respectively welded and fixed in the two slots 21.
[0041] like Figure 3 As shown, to ensure the stability of the structure, the fixing rod 6 is positioned directly above the first crossbar, and a support base 22 is provided at the bottom of the fixing rod 6.
[0042] Furthermore, on a single fixed rod 6, two mounting members 7 are provided vertically. Each mounting member 7 includes a sleeve portion 701 and an extension post 702. The sleeve portion 701 is sleeved and fixed on the fixed rod 6, and the longitudinal rotating member 8 is clamped and fixed on the extension post 702.
[0043] Furthermore, combined with Figure 5-6 As shown, the longitudinal rotating member 8 has an insertion hole 23. The fixed bent rod 9 slides up and down in the insertion hole 23. The insertion hole 23 is formed by clamping. The insertion hole 23 is opened and closed by fasteners to tighten or loosen.
[0044] In summary, this application achieves lateral movement of the sliding member 13 and the movable plate 2 through the main slide rail 11 and the top slide rail 12, while the rotating member 14 can deflect the extended shelf and vehicle fixing components on it as a whole, moving the bicycle outward and downward for easy disassembly or loading. In addition, the tension spring 15 can also make it easier to reset, which has the advantages of simple and convenient operation, safety and efficiency.
