Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically a novel folding shock-absorbing portable bicycle. Background Technology

[0002] Folding bikes are a category of bicycles: folding bicycles generally consist of a frame folding joint and a seat tube folding joint. By folding the frame, the length can be reduced by about 45%, making them very convenient to carry and able to be put into a folding bag or car trunk.

[0003] Existing children's folding bicycles have two wheels that are folded onto the same axis. Although the size of the bicycle is reduced after folding, the lack of stable support due to the two wheels being on the same axis makes it easy to tip over when transporting it, which increases the burden on children, especially. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a new type of folding shock-absorbing portable bicycle to solve the technical problem that the two wheels are on the same axis, lack stable support, and are easy to tip over during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel folding shock-absorbing portable bicycle, including a pole, a support assembly inserted into the bottom end of the pole, the support assembly including a first support mechanism, the first support mechanism including a post, a rotating plate rotatably connected to both sides of the bottom end of the post via a torsion shaft, a first support wheel rotatably connected to one end of the rotating plate, and limit blocks fixedly connected to both sides of the post;

[0006] The bottom of the upright has two first through holes, and the insert has a first through hole. A first nut is fixedly connected to one side of the two first through holes at a position opposite to each other, and a first fixing rod is threadedly connected to the first nut.

[0007] By adopting the above technical solution, and by designing the support components to be inserted into the bottom of the pole, a stable support base is provided for the bicycle. The combination of the insert post, rotating plate and first support wheel in the first support mechanism allows the bicycle to stand stably on the ground when folded, which is both convenient to carry and saves space.

[0008] Furthermore, two rotating beams are rotatably connected to one side of the upright, and a sleeve is rotatably connected to one end of each rotating beam.

[0009] By adopting the above technical solution, the two rotating beams rotatably connected on one side of the pole provide the necessary support and rotation space for the folding of the handlebars.

[0010] Furthermore, the sleeve is rotatably connected to a foldable handlebar, and the upright, two rotating beams and the handlebar form a parallelogram structure.

[0011] By adopting the above technical solution, the parallelogram structure formed by the foldable handlebar, upright, and rotating beam connected inside the sleeve ensures the stability and smoothness of the handlebar during folding and unfolding.

[0012] Furthermore, a rear vehicle seat is rotatably connected to the top of the other side of the upright, and a rear wheel frame is rotatably connected to the bottom of the other side of the upright.

[0013] By adopting the above technical solution, the rear seat, which is rotatably connected to the top of the other side of the pole, and the rear wheel frame, which is rotatably connected to the bottom, provide a complete rear structure for the bicycle.

[0014] Furthermore, a connecting frame is rotatably connected to one end of the rear seat, and the connecting frame is rotatably connected to the rear wheel frame. The rear seat, connecting frame, rear wheel frame, and upright form a parallelogram structure, and a rear wheel is rotatably connected to one end of the rear wheel frame.

[0015] By adopting the above technical solution, the parallelogram structure formed by the rear seat, connecting frame, rear wheel frame and upright further enhances the stability and strength of the rear of the bicycle.

[0016] Furthermore, a tensioning mechanism is provided on one side of the rear wheel. The tensioning mechanism includes a fixed block, a mounting plate is rotatably connected to one side of the fixed block, a torsion spring that provides elastic force is provided between the mounting plate and the fixed block, and a tensioning wheel is rotatably connected to one end of the mounting plate.

[0017] By adopting the above technical solution, the tensioning mechanism set on one side of the rear wheel provides the necessary tension for the bicycle chain or drive belt, ensuring the accuracy and stability of the transmission.

[0018] Furthermore, a sliding frame is slidably connected to the top of the upright, and shock absorbers are rotatably connected to both sides of the sliding frame. One of the shock absorbers is rotatably connected to the rotating beam, and the other shock absorber is rotatably connected to the rear wheel frame.

[0019] By adopting the above technical solution, the sliding frame slidably connected to the top of the pole and the shock absorbers rotatably connected to both sides provide an effective shock absorption system for the bicycle.

[0020] Furthermore, the top of the upright has two second through holes, the sliding frame has an insertion hole, and a second nut is fixedly connected to one side of the sliding frame. The second nut is threadedly connected to a second fixing rod.

[0021] By adopting the above technical solution, the two second through holes opened at the top of the pole and the insertion holes opened on the sliding frame provide the necessary space and position for the insertion and fixation of the second fixing rod.

[0022] Furthermore, the support assembly includes a second support mechanism, which includes a rotating shaft. The rotating shaft is fixedly connected to the bottom of the upright, and second support wheels are rotatably connected to both ends of the rotating shaft.

[0023] By adopting the above technical solution, the second support mechanism included in the support assembly provides another support structure for the bicycle. The rotatable connection between the rotating shaft and the bottom of the pole allows the second support mechanism to rotate and fold flexibly as needed.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the setting of a first support mechanism of upright pole and support components, with the upright pole serving as the main support structure of the entire bicycle, and the first support mechanism of the support components, through the ingenious combination of components such as insert post, rotating plate, first support wheel and limiting block, achieves stable support for the bicycle in the folded state, so that the bicycle can stand upright after folding, making it convenient for users to carry and store, and also improving the adaptability and durability of the bicycle in the outdoor environment. The first support wheel can also provide additional support, and the rotation of the rotating plate can provide stronger support, so that the bicycle can provide additional support conditions for the user, thereby ensuring the stability and safety of the bicycle during use;

[0026] 2. By setting up a second support mechanism, a rotating shaft, and a second support wheel, this utility model provides an alternative support method for the bicycle, further enhancing its stability and support. This allows the bicycle to stand more stably on the ground when folded and parked, reducing the risk of swaying and tipping caused by uneven ground or wind. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A new type of folding, shock-absorbing portable bicycle, such as Figures 1-4 As shown, it includes a pole 1, and a support assembly 2 is inserted into the bottom end of the pole 1. The support assembly 2 includes a first support mechanism 21, and the first support mechanism 21 includes a post 211. The bottom ends of the post 211 are rotatably connected to a rotating plate 212 via a torsion shaft. One end of the rotating plate 212 is rotatably connected to a first support wheel 213. Limiting blocks 217 are fixedly connected to both sides of the post 211.

[0036] The bottom of the upright 1 has two first through holes 214. The insert 211 has a first through hole 214. A first nut 215 is fixedly connected to one side of the two first through holes 214 at a relative position. The first nut 215 is threadedly connected to a first fixing rod 216. The setting of the limiting block 217 effectively prevents the rotating plate 212 from rotating excessively, ensuring the stability and safety of the structure. Through the cooperation of the first through hole 214, the first nut 215 and the first fixing rod 216, the position of the insert 211 can be easily fixed and adjusted, making it quick.

[0037] See Figure 1Two rotating beams 3 are rotatably connected to one side of the upright pole 1. A sleeve 4 is rotatably connected to one end of the rotating beam 3. The sleeve 4 rotatably connected to one end of the rotating beam 3 allows the handlebar 5 to rotate, which facilitates subsequent folding and unfolding, meeting the needs of different usage scenarios. This not only improves the portability of the bicycle, but also allows the handlebar 5 to fit more tightly to the bicycle frame when folded, reducing the space occupied.

[0038] See Figure 1 The sleeve 4 has a rotating connection to a foldable handlebar 5, a stem 1, two rotating beams 3, and the handlebar 5 forming a parallelogram structure. This allows the handlebar 5 to distribute the force more evenly during riding, improving riding comfort and safety. The stability of the parallelogram structure also makes the bicycle more stable during riding, reducing vibrations caused by bumps.

[0039] See Figure 1 The rear seat 6 is rotatably connected to the top of the other side of the upright 1, and the rear wheel frame 7 is rotatably connected to the bottom of the other side of the upright 1. This allows the rear seat 6 and the rear wheel frame 7 to rotate and fold relatively independently, improving the flexibility and portability of the bicycle. In addition, the rear seat 6 provides users with extra riding or storage space, enhancing the practicality and versatility of the bicycle.

[0040] See Figure 1 One end of the rear seat 6 is rotatably connected to a connecting frame 8, which is rotatably connected to the rear wheel frame 7. The rear seat 6, connecting frame 8, rear wheel frame 7 and upright 1 form a parallelogram structure. One end of the rear wheel frame 7 is rotatably connected to the rear wheel 9, which allows the rear wheel 9 to be more stably mounted on the rear wheel frame 7, improving riding safety and stability. The setting of the connecting frame 8 also allows the rear wheel frame 7 and the rear seat 6 to rotate and fold more flexibly, further improving the portability and flexibility of the bicycle.

[0041] See Figure 3 A tensioning mechanism 10 is provided on one side of the rear wheel 9. The tensioning mechanism 10 includes a fixing block 101. A mounting plate 102 is rotatably connected to one side of the fixing block 101. A torsion spring that provides elastic force is provided between the mounting plate 102 and the fixing block 101. A tensioning wheel 103 is rotatably connected to one end of the mounting plate 102. The combination of the fixing block 101, the mounting plate 102 and the tensioning wheel 103 in the tensioning mechanism 10 enables the chain to maintain tension even after folding. The torsion spring allows the tensioning mechanism 10 to automatically adapt to the elongation and shortening of the chain during folding, further improving the reliability and durability of the transmission.

[0042] See Figure 1A sliding frame 11 is slidably connected to the top of the upright 1. Shock absorbers 12 are rotatably connected to both sides of the sliding frame 11. One shock absorber 12 is rotatably connected to the rotating beam 3, and the other shock absorber 12 is rotatably connected to the rear wheel frame 7. The shock absorber 12 is rotatably connected to the rotating beam 3 and the rear wheel frame 7 respectively, so that the shock absorption system can more comprehensively cover the entire vehicle body, improving riding comfort and stability. The sliding of the sliding frame 11 also allows the position and angle of the shock absorber 12 to be adjusted as needed, further enhancing the adaptability and flexibility of the shock absorption system.

[0043] See Figure 1 The top of the upright 1 has two second through holes 13, and the sliding frame 11 has an insertion hole 14. A second nut 15 is fixedly connected to one side of the sliding frame 11. The second nut 15 is threadedly connected to a second fixing rod 16. The threaded connection between the second nut 15 and the second fixing rod 16 allows the position and height of the sliding frame 11 to be adjusted and fixed as needed, further enhancing the stability and adaptability of the bicycle and improving the performance and effect of the shock absorption system.

[0044] The implementation principle of this utility model is as follows: First, when folding is required, rotate the second fixing rod 16 to pull the second fixing rod 16 out of the second through hole 13, pull the sliding frame 11, and drive the handlebars 5 and the rear seat 6 to fold upward. Then, reinsert the second fixing rod 16 into another second through hole 13 and tighten the second nut 15 again, so that the bicycle body can be folded. After folding, the wheels still maintain the front and rear distribution, and at the same time, the first support wheel 213 at the bottom contacts the ground, so that the bicycle can stand stably on the ground.

[0045] When unfolded, if additional support is needed, rotate the first fixing rod 216 to pull it out and pull down the insert 211 so that the first support wheel 213 at the bottom of the insert 211 can contact the ground and rotate to both sides. At this time, the limiting block 217 supports the rotating plate 212, so that an outward-opening support structure can be formed, which improves the stability of riding.

[0046] Example 2:

[0047] See Figure 4 The support component 2 includes a second support mechanism 22, which includes a rotating shaft 221. The rotating shaft 221 is fixedly connected to the bottom of the upright 1. The two ends of the rotating shaft 221 are rotatably connected to second support wheels 222. The setting of the second support wheels 222 also enables the bicycle to stand more stably on the ground when folded, improving the portability and safety of the bicycle. It not only enhances the stability and support of the bicycle, but also provides users with a more convenient and flexible user experience.

[0048] The implementation principle of this utility model is as follows: First, through the second support mechanism 22, a stable support can be formed after folding, making it convenient for the user to pull the bicycle to move.

[0049] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
