Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically to an endurance road bicycle. Background Technology

[0002] Road bikes are racing bikes designed specifically for paved roads. They are characterized by lightweight design, high speed, and low wind resistance. They are mainly used for competition, sports, or efficient commuting. To meet the needs of riders for long-distance continuous riding, endurance road bikes are needed to ensure the rider's comfort and stability during long-distance rides.

[0003] Existing endurance road bikes mostly improve rider comfort by absorbing shock at the saddle. However, their shock absorption methods are mostly mechanical springs, which are difficult to achieve ideal results. Furthermore, the vibration at the handlebars also increases the rider's hand strain due to the need to hold the handlebars for extended periods. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: an endurance road bicycle, comprising a frame, with wear-resistant wheels provided on both sides of the bottom of the frame, a support rod for supporting the rider, a connecting rod slidably connected inside the support rod, a seat fixedly mounted on the top of the connecting rod, the support rod being made entirely of carbon fiber, a shock-absorbing component for elastically supporting the connecting rod being provided inside the support rod, a handlebar being provided at the top of the front end of the frame, four mounting grooves being arrayed on the outer side of the handlebar, the handlebar having a straight handlebar section and a curved handlebar section, and both the straight and curved handlebar sections being fitted with shock-absorbing handlebar sleeves.

[0005] As an optimization, the shock absorption assembly includes a sealing plate one and a sealing plate two fixedly installed inside the support rod, and a sealed cavity is formed between the sealing plate one and the sealing plate two. A sliding rod is inserted into the center of the sealing plate one, and a piston is fixedly installed at the bottom end of the sliding rod. The piston is slidably connected inside the sealed cavity, and the top end of the sliding rod is fixedly installed at the bottom end of the support rod. The compression of the air in the sealed cavity during riding plays a role in shock absorption and buffering.

[0006] As an optimization, a collar is fitted on the outer side of the section of the slide rod located inside the sealing cavity. A compression spring is fixedly installed between the collar and the sealing plate. The piston has through holes on both sides of the slide rod. By squeezing and compressing the gas back and forth, the buffering and shock absorption effect is further improved.

[0007] As an optimization, a limiting plate is fixedly installed at the bottom of the connecting rod, and limiting grooves are opened on both sides of the inner wall of the support rod. The limiting plate is slidably connected in the limiting groove to limit the movement, so that the connecting rod can only slide in a straight line.

[0008] As an optimization, the handle cover is composed of a sleeve base, a shock-absorbing layer and a rubber sleeve, with the sleeve base located inside the center of the rubber sleeve and the shock-absorbing layer located outside the sleeve base and between the rubber sleeve.

[0009] As an optimization, the sleeve base is made of carbon steel, and the inner wall of the sleeve base is provided with four sets of protrusions. The protrusions are slidably inserted into the grooves, and the protrusions play a limiting role inside the grooves, restricting the rotation of the sleeve base and improving stability.

[0010] As an optimization, the shock-absorbing layer is honeycomb-shaped and made of sponge material. The honeycomb sponge can play a shock-absorbing role.

[0011] The beneficial effects of this utility model are:

[0012] This endurance road bike uses a sliding rod to move a through-hole along the inner wall of a sealed cavity, thus compressing the air inside the sealed cavity for shock absorption. At the same time, the internal air is expelled upwards along the through-hole, which in turn compresses the collar and the compression spring. The spring's own elasticity then causes the collar to return to its original position, which in turn forces the gas back into the bottom of the sealed cavity. This assists the piston in sliding back and forth, further improving the shock absorption and making the ride more stable and comfortable.

[0013] This endurance road bike features a protrusion that slides into a groove to limit the rotation of the sleeve base, improving stability. The honeycomb-shaped, sponge-material shock-absorbing layer further reduces vibrations transmitted to the hands, thus reducing hand strain. Attached Figure Description

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 An endurance road bicycle includes a frame 1, with wear-resistant wheels 2 on both sides of the bottom of the frame 1. The frame 1 has a support rod 3 for supporting the rider, and a connecting rod 4 is slidably connected inside the support rod 3. A limiting plate 16 is fixedly installed at the bottom of the connecting rod 4. Limiting grooves 17 are opened on both sides of the inner wall of the support rod 3, and the limiting plate 16 is slidably connected in the limiting grooves 17 to limit the movement, so that the connecting rod 4 can only slide in a straight line. A seat 5 is fixedly installed at the top of the connecting rod 4. The support rod 3 is made of carbon fiber. A shock-absorbing component for elastically supporting the connecting rod 4 is set inside the support rod 3. A handlebar 6 is set at the top front of the frame 1. Four mounting grooves are arranged on the outer side of the handlebar 6. The handlebar 6 has a straight handlebar part and a curved handlebar part, and both the straight handlebar part and the curved handlebar part of the handlebar 6 are covered with a handlebar sleeve 7 for shock absorption.

[0021] Please see Figure 2The shock absorption assembly includes a sealing plate 8 and a sealing plate 9 fixedly installed inside the support rod 3, and a sealed cavity 10 is formed between the sealing plate 8 and the sealing plate 9. A sliding rod 11 is inserted into the center of the sealing plate 8. A piston 12 is fixedly installed at the bottom end of the sliding rod 11 and is slidably connected inside the cavity 10. The top end of the sliding rod 11 is fixedly installed at the bottom end of the support rod 3. When riding, the connecting rod 4 can slide inside the support rod 3 by sitting on the seat 5 and causing the sliding rod 11 to drive the through hole 15 to slide along the inner wall of the cavity 10, thereby compressing the air inside the cavity 10 for shock absorption.

[0022] Please see Figure 2 A collar 13 is fitted on the outer side of a section of the slide rod 11 inside the sealing cavity 10. A compression spring 14 is fixedly installed between the collar 13 and the sealing plate 8. A through hole 15 is provided on both sides of the piston 12. When the piston 12 slides and compresses the air in the sealing cavity 10, the internal air can be discharged upward along the through hole 15, which will squeeze the collar 13 to slide upward along the outer wall of the slide rod 11, thus compressing the compression spring 14. The compression spring 14 itself will drive the collar 13 to return downward, which will then squeeze the gas into the bottom of the sealing cavity 10 along the through hole 15. Therefore, it can assist the piston 12 to slide back and forth, further improving the buffering and shock absorption effect, making the ride more stable and improving the riding comfort.

[0023] Please see Figure 3 The handle cover 7 consists of a sleeve base 18, a shock-absorbing layer 19, and a rubber sleeve 20. The sleeve base 18 is located inside the center of the rubber sleeve 20, and the shock-absorbing layer 19 is located between the outer side of the sleeve base 18 and the rubber sleeve 20. The sleeve base 18 is made of carbon steel, and four sets of protrusions 21 are arranged in an array on the inner wall of the sleeve base 18. The protrusions 21 are slidably inserted into the grooves. The protrusions 21 play a limiting role in the grooves, restricting the rotation of the sleeve base 18 and improving stability. The shock-absorbing layer 19 is honeycomb-shaped and made of sponge material. The honeycomb sponge can play a shock-absorbing role, weakening the vibration transmitted to the hand and reducing the burden on the hand.

[0024] During long-distance cycling, the rider needs to sit on the seat 5, which will cause slight bumps and vibrations. This will cause the connecting rod 4 to slide downwards along the inner wall of the support rod 3. Consequently, the sliding rod 11 will cause the through hole 15 to slide along the inner wall of the sealing cavity 10, thereby compressing the air inside the sealing cavity 10 for shock absorption. At the same time, when the piston 12 slides and compresses the air inside the sealing cavity 10, the internal air will be discharged upwards along the through hole 15, which will squeeze the collar 13 to slide upwards along the outer wall of the sliding rod 11. This will compress the compression spring 14, and the elasticity of the compression spring 14 will drive the collar 13 to return downwards, which will then squeeze the gas back into the bottom of the sealing cavity 10 along the through hole 15. This will assist the piston 12 in sliding back and forth, further improving the shock absorption effect.

[0025] In summary, this endurance road bicycle uses the compression rod 11 to drive the through hole 15 to slide along the inner wall of the sealed cavity 10, thus compressing the air inside the sealed cavity 10 for shock absorption. At the same time, the internal air is discharged upward along the through hole 15, which in turn compresses the collar 13 to compress the compression spring 14. Then, the compression spring 14 uses its own elasticity to drive the collar 13 to return to its original position, which in turn squeezes the gas into the bottom of the sealed cavity 10, thus assisting the piston 12 to slide back and forth, thereby further improving the shock absorption effect, making the ride more stable and improving the riding comfort.

[0026] By sliding the protrusion 21 into the groove, it can serve as a limit, restricting the rotation of the sleeve base 18 and improving stability. Furthermore, the honeycomb-shaped shock-absorbing layer 19 made of sponge material can provide shock absorption, thereby reducing the vibration transmitted to the hand and reducing the burden on the hand.
