Detailed Implementation

[0030] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the following description of the present invention with reference to the accompanying drawings is merely illustrative and not restrictive.

[0031] Where possible, the various embodiments described below can be rearranged to form other embodiments not shown in the following description; the various technical features described below can also be rearranged to form other embodiments not shown in the following description.

[0032] Example 1

[0033] Please see Figure 1-6To reduce the storage volume of bicycle cup holders, this embodiment provides a foldable bicycle cup holder, including a first bracket 1 for connecting to the bicycle frame 18; a first clamping assembly movably connected to the top of the first bracket 1; a base 3 movably connected to the bottom of the first bracket 1; and a second bracket 4 slidably connected to the side of the first bracket 1 away from the frame 18. The second bracket 4 drives the first clamping assembly and the base 3 to rotate synchronously relative to the first bracket 1. In use, the first clamping assembly and the base 3 are confined to the side of the first bracket 1 away from the frame 18 and form a placement space perpendicular to the frame 18. In the folded state, the first clamping assembly is fastened to the frame 18, and the base 3 is fastened to the second bracket 4. Folding the first clamping assembly and the base 3 separately reduces the overall volume of the bicycle cup holder when stored.

[0034] A gear 5 is movably connected to the top of the first bracket 1 via a shaft 16. The central axis of the shaft 16 is perpendicular to the central axis of the frame 18. The first clamping assembly is mounted on the shaft 16 of the gear 5, thereby driving the first clamping assembly to rotate along the central axis. The second bracket 4 is movably connected to the first bracket 1 and located on the side of the first bracket 1 away from the frame 18. The second bracket 4 is provided with a rack 6 that meshes with the gear 5. The linear movement of the second bracket 4 allows the rack 6 to drive the gear 5 to rotate. The meshing tooth ratio of the gear 5 and the rack 6 is 2:1. When the second bracket 4 moves to its limit position in a single movement, the gear 5 rotates exactly half a turn, thereby realizing the switching between the use and storage states of the first clamping assembly.

[0035] The bottom of the second bracket 4 has a through groove, through which the base 3 passes. The side of the base 3 has a groove rail 9. The second bracket 4 has a protrusion 10 that slidably rests on the groove rail 9. To improve structural stability, both sides of the base 3 are equipped with a mating structure between the groove rail 9 and the protrusion 10 to cooperate with the second bracket 4. In use, the protrusion 10 is positioned at the end of the groove rail 9 closest to the first bracket 1, thus limiting the base 3 to be perpendicular to the frame 18. The linear movement of the second bracket 4 simultaneously moves the protrusion 10 away from the first bracket 1 along the guide rail, causing the base 3 to flip towards the first bracket 1. Finally, the base 3 is limited to a position at approximately a 20° angle to the first bracket 1.

[0036] To further ensure that the second support 4 can only move up and down, one of the first support 1 and the second support 4 is provided with a limiting groove 7, and the other is provided with a limiting block 8. The limiting block 8 can be slidably disposed in the limiting groove 7. The distance that the limiting block 8 can slide is the distance that the first support 1 can move. This distance is just enough to drive the first clamping component to rotate 180° and the base 3 to rotate about 70°.

[0037] To further enhance the support strength of the base 3, a plate 11 is provided at the end of the base 3 away from the first support 1. When in use, the plate 11 is located at the center of the bottom of the cup. The second support 4 is provided with a storage groove 12. The plate 11 in the storage state is embedded in the storage groove 12. To achieve a better storage effect for the plate 11, since the side of the storage groove 12 facing the base 3 is an inclined surface 13, the plate 11 in the storage state is attached to the inclined surface 13.

[0038] To facilitate the assembly and disassembly of the first bracket 1 and the frame 18, the first bracket 1 is provided with two sets of second clamping components, one above the other. Each second clamping component includes two symmetrically arranged single claws. In this embodiment, the frame 18 is a circular seat post under the bicycle seat. The two single claws are set as arc-shaped structures, clamping the two single claws to the outer wall of the circular seat post and fixing them to the side of the first bracket 1 away from the second bracket 4 by means of threaded connection, thereby realizing the installation of the cup holder.

[0039] To facilitate the application of force to the second support 4, inward grooves 15 are provided on both sides of the second support 4 in the direction of movement. Each side has two grooves 15, one above the other, which are used for gripping with fingers, making it easier to apply force to move the second support 4 up and down.

[0040] This embodiment provides a foldable bicycle cup holder, the principle and specific operation of which are as follows: When storing, the second bracket 4 is pushed upwards, and the rack 6 moves upwards synchronously with the second bracket 4, driving the gear 5 to rotate 180°. The gear 5 drives the shaft 16 to rotate, and the shaft 16 drives the first clamping assembly to rotate counterclockwise 180°. At the same time, the second bracket 4 drives the base 3 to rotate counterclockwise by about 70°. When the second bracket 4 is pushed to its limit position, the clamping assembly is fastened to the frame 18. The base 3 moves with the rail 9 to a position with an angle of about 20° with the first bracket 1. 1 is located in the storage slot 12; when in use, push the second bracket 4 downward, the rack 6 moves downward synchronously with the second bracket 4, driving the gear 5 to rotate 180°, the gear 5 drives the shaft 16 to rotate, the shaft 16 drives the first clamping assembly to disengage from the frame 18 and rotate clockwise 180°, at the same time, the second bracket 4 drives the base 3 to rotate clockwise about 70°, push the second bracket 4 to the limit position, the clamping assembly and the base 3 move to a state perpendicular to the frame 18, at this time the clamping assembly is located directly above the base 3, thus forming a placement space, where a water cup can be placed.

[0041] Example 2

[0042] Please see Figure 1-6To accommodate water cups of different sizes, this embodiment provides a foldable bicycle cup holder based on Embodiment 1. The first clamping component includes two elastic claw arms 2 symmetrically arranged on both sides of the gear 5, with the ends of the two elastic claw arms 2 away from the first bracket 1 abutting against each other. Each elastic claw arm 2 can be connected to the shaft 16 via a hexagonal stud 17. During bicycle riding, this connection method not only provides anti-loosening and shock absorption but also forms a detachable structure. Since water cups can have different shapes, the first clamping component mainly clamps and fixes the upper part of the water cup. The detachable connection structure allows for changing the type of elastic claw arm 2 according to the shape of the water cup, thereby improving the flexibility of use. The elastic claw arms 2 are linked to the gear 5 through the shaft 16; the two elastic claw arms 2 will rotate in the same direction by the same degree as the gear 5 rotates.

[0043] To facilitate the placement of the water cup, the water cup in this embodiment can be a round kettle. The elastic claw arm 2 extends from the abutment and has a folding part 14, with the two folding parts 14 forming an opening facing away from the placement space. The elastic claw arm 2 is made of soft rubber and has an arc-shaped structure, allowing it to change shape according to the size of the kettle. When the gear 5 drives the elastic claw arm 2 to flip to one side of the frame 18, the frame 18 is located at the opening of the two folding parts 14. If the elastic claw arm 2 continues to flip, the frame 18 can separate the abutment of the two elastic claw arms 2. When the frame 18 moves away, the two elastic claw arms 2 return to the abutment state, thus automatically achieving the storage effect of the elastic claw arms 2 wrapping around the frame 18. If needed, the frame 18 separates the two elastic claw arms 2 again, allowing the elastic claw arms 2 to automatically detach from the frame 18 and move to the other side. The kettle is horizontally aligned with the opening of the folding part 14 and force is applied towards the second bracket 4, which can quickly clamp the kettle between the two elastic claw arms 2.

[0044] To improve the elastic deformation of the elastic claw arm 2, the elastic claw arm 2 includes a first arm body 21 and a second arm body 22. The first arm body 21 and the second arm body 22 are integrally formed at one end near the first support 1, forming a space in the middle, and the other end is abutted against it. This structure allows the first clamping assembly to form multiple individual elastic clamping flaps, which not only enables the elastic claw arm 2 to generate greater elastic deformation, thereby adapting to a larger range of kettle sizes, but also makes the clamping force more uniform and gentle, and reduces the use of materials, thus reducing costs.

[0045] Although several specific embodiments of the present invention have been shown and described above, it is understood that the above embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art are within the scope of protection claimed by the present invention.
