Description

Technical Field

[0001] This invention relates to the field of bicycle parts technology, specifically to a rotary oil-cooled handlebar structure and a bicycle. Prior Technology

[0002] Currently, the common brake line routing methods for various bicycles on the market mainly adopt the internal routing method in the frame, that is, the brake line connecting to the rear brake down pump extends to the stem below the handlebars and passes through the stem, while the front part still adopts the external routing method, with the brake line connecting to the front brake down pump directly using the external routing method.

[0003] Exposed brake lines not only look unattractive, but they are also more likely to be touched by objects while riding, affecting riding safety and experience. At the same time, for aesthetic reasons, the brake lines that run into the frame need to be as short as possible when exposed, but this creates a new problem: when the vehicle turns, the internal brake lines will be pulled, pulled or twisted as the column rotates, posing a significant safety hazard and greatly reducing the lifespan of the brake lines.

[0004] Therefore, we propose a rotating oil-filled head structure and a bicycle.

[0061] In related technologies, exposed brake lines not only have poor aesthetics, but also pose a risk of being touched by external objects while riding, affecting riding safety and experience. At the same time, for aesthetic reasons, the brake lines that run into the frame need to be as short as possible when exposed, but this creates a new problem: when the vehicle turns, the internal brake lines will be pulled, stretched, or twisted as the column rotates, posing a significant safety hazard and greatly reducing the lifespan of the brake lines.

[0062] Based on the above, embodiments of the present invention provide a rotary oil-driven vehicle head structure and a bicycle, which will be described in detail below with reference to specific embodiments and figures.

[0063] Example 1

[0064] Embodiment 1 of the present invention provides a rotary oil-passing vehicle front structure. Figure 1 is a perspective view of the rotary oil-passing vehicle front structure according to a first exemplary embodiment. Figure 2 is a first-view cross-sectional view of the rotary oil-passing vehicle front structure according to the first exemplary embodiment. Figure 3 is a second-view cross-sectional view of the rotary oil-passing vehicle front structure according to the first exemplary embodiment. As shown in Figures 1-3, this rotary oil-passing vehicle front structure is used with a bicycle frame, the bicycle frame having a tube member 50, the tube member 50 being a head tube, which is fixed to the front end of the bicycle frame; it also includes:

[0065] The main core component 10 is cylindrical and includes at least: a first oil passage 100 and a second oil passage 101 axially opened inside the main core component 10; a first core portion 102 and a second core portion 103 arranged axially in sequence; a first annular groove 104 opened on the annular outer wall of the first core portion 102; and a first oil inlet radially opened in the second core portion 103 and connected to the first end of the first oil passage 100, a first oil outlet axially connected to the second end of the first oil passage 100, and a second oil inlet radially opened in the second core portion 103 and connected to the first end of the second oil passage 101; wherein the second end of the second oil passage 101 is radially connected to the first annular groove 104; a first protruding ring portion 105 is also provided on the annular side wall of the first core portion 102;

[0066] The rotating component 40 includes at least a rotating sleeve 401, which is movably sleeved on the second core 103 at the position corresponding to the first annular groove 104, and a second oil outlet 403 radially communicating with the first annular groove 104 is opened on the side wall corresponding to the first annular groove 104;

[0067] A locking element is provided at the second core 103 position to achieve axial positioning of the main core 10 on the tube body 50;

[0068] In the above embodiments, referring to Figures 1-3, the first oil inlet is connected to the front brake upper pump via a first oil pipe 701; the second oil inlet is connected to the rear brake upper pump via a second oil pipe 702; the first oil outlet is connected to the rear brake lower pump via a third oil pipe 703; and the second oil outlet 403 is connected to the front brake lower pump via a fourth oil pipe 704. It is understood that quick-connect couplings can be pre-installed on the oil pipes to facilitate rapid connection. Quick-connect couplings are existing technology, and those skilled in the art can access them through public information. It is understood that this exemplary embodiment uses the quick-connect structure of the oil pipe disclosed in Chinese Patent ZL202411928412.1, which will not be described in detail here. The third oil pipe 703 runs inside the bicycle frame and extends near the rear brake down pump to connect to the rear brake down pump, thus achieving a fully concealed assembly of the third oil pipe 703; the second oil outlet 403 is close to the front wheel of the bicycle frame, and the fourth oil pipe 704 can be directly close to the front brake down pump at the front wheel of the bicycle frame, thereby minimizing the exposure of the fourth oil pipe 704 and achieving a concealed assembly;

[0069] When the rear brake is applied, the upper pump of the rear brake works to input oil through the second oil pipe 702 into the second oil inlet 205, and then the oil is output to the lower pump of the rear brake through the third oil pipe 703, thus achieving hydraulic braking. When the front brake is applied, the upper pump of the front brake works to input oil through the first oil pipe 701 into the first oil inlet, and then the oil is output to the lower pump of the front brake through the first annular groove 104 and then to the fourth oil pipe 704, thus achieving hydraulic braking.

[0070] When the bicycle turns, the handlebars drive the main core component 10 and the fork connected to the main core component 10 to rotate inside the tube body component 50 to achieve the steering function. The third oil pipe 703 runs through the tube body component 50 into the bicycle frame for fully concealed assembly. The third oil pipe 703 can rotate with the steering without causing the oil pipe to twist and be damaged. The rotating component 40 is movably sleeved on the main core component 10. Therefore, the fourth oil pipe 704 connected to the second oil outlet 403 on the rotating component 40 will not rotate with the steering and cause the oil pipe to twist and be damaged. There is no need to reserve an exposed steering length for the oil pipe. It can be concealed and assembled internally, improving the aesthetics of the vehicle and avoiding damage to the exposed oil pipe.

[0071] Meanwhile, in this embodiment, referring to Figures 1 to 3, further optimizations were made to the external leakage part of the oil outlet. A third oil pipe 703 extending axially along the outer wall of the rotating part 40 is connected to the first oil outlet through a movable oil plug. Parts of the movable oil plug and the third oil pipe 703 are hidden and assembled in the oil pipe chamber 501 opened on the side wall of the pipe body part 50.

[0072] Referring again to Figures 1-3, in an optional embodiment, the rotating member 40 further includes:

[0073] The step 402 is located in the middle of the axial inner wall of the rotating sleeve 401 and is positioned at the first annular groove 104 after assembly. The first groove 4021 and the second groove 4022 are formed sequentially from the middle to the sides of the axial inner wall of the rotating sleeve 401. The second oil outlet 403 is located in the middle of the step 402.

[0074] Two rotary sealing rings 404 are respectively assembled in the first groove 4021 and sleeved on the annular outer wall of the first core 102 to prevent oil leakage in the first annular groove 104;

[0075] Two bearings 405 are respectively assembled in the second slot 4022, and their inner rings are tightly fitted with the first core 102 to maintain the rotational assembly of the rotating component 40 on the main core 10. In this embodiment, the bearings 405 are deep groove ball bearings. Further, referring to Figures 2 and 3, after the two bearings 405 are assembled on opposite sides, they are pressed together and the rotary sealing ring 404 is axially positioned to seal the second oil passage 101.

[0076] In the above embodiment, the setting of the rotary sealing ring 404 effectively ensures the sealing of the annular oil circuit, prevents oil leakage and avoids dust entry. At the same time, the setting of the bearing 405 also reduces the rotational friction of the rotary component 40 on the main core component 10, ensuring smooth steering and not damaging the oil circuit.

[0077] Referring again to Figures 1-3, in this embodiment, the locking element includes:

[0078] The first locking member 20 is sleeved on the second core 103 and limited by the first protruding ring 105, and the outer edge of the first locking member 20 abuts against the edge of the first end of the tube body 50;

[0079] The second locking member 60 is assembled to the second end of the tube body 50 and threadedly assembled to the second end of the second core 103 to cooperate with the first locking member 20 to axially position the main core 10 and the rotating member 40; wherein, the second locking member 60 specifically includes:

[0080] The second locking sleeve 604 has its first end sleeved on the second end of the second core 103, and its first end abuts against the rotating member 40 to cooperate with the first locking member 20 to axially position the rotating member 40. The second end of the second locking sleeve 604 has an integrally formed second annular protrusion 6041 in a stepped shape.

[0081] The second nut 605 is disposed in the assembly groove in the middle of the second locking sleeve 604 and threadedly assembled with the second end of the second core 103 to push against the assembly position of the positioning rotating part 40;

[0082] A locking block 606 is inserted into a keyway formed between the second locking sleeve 604 and the second core 103 to radially position the second locking sleeve 604.

[0083] The first bowl assembly 607 is sleeved on the second end of the second locking sleeve 604 and its inner end abuts against the second annular protrusion 6041. Its outer end is integrally formed with a stepped third annular protrusion 6071, which abuts against the second end of the pipe body 50 to form a fastening structure.

[0084] In the above embodiment, during assembly, the third oil pipe 703 is first threaded through the bicycle frame, then the first locking member 20 is installed at the upper end of the pipe body 50, and the first core 102 of the main core member 10 is inserted.

[0085] The first cup assembly 607 is fitted onto the second locking sleeve 604, and the first core 102 of the main core 10 is fitted onto the second locking sleeve 604. The locking block 606 is inserted from the lower part of the second locking sleeve 604 and inserted into the keyway formed between the second locking sleeve 604 and the first core 102 to radially position the second locking sleeve 604. Then, the second nut 605 is screwed into the lower part of the second locking sleeve 604 until the third annular protrusion 6071 of the first cup assembly 607 abuts against the second end of the tube body 50 to form a fastening structure. It should be noted that the above assembly steps in this embodiment are consistent with the overall assembly steps of existing bicycles. There is no need to change the existing assembly habits of workers when assembling the whole vehicle. It can be directly replaced, and the assembly is faster.

[0086] Subsequently, the fourth oil pipe 704 is connected to the second oil outlet 403, the third oil pipe 703 is connected to the first oil outlet, the first oil pipe 701 is connected to the first oil inlet, and the second oil pipe 702 is connected to the second oil inlet, thus completing the oil circuit connection.

[0087] Furthermore, in this embodiment, a riser tube 80 is also included. The riser tube 80 is hollow inside, and one end of it is fitted onto the first core 102 to conceal the assembly of the first oil pipe 701 and the second oil pipe 702. Furthermore, the first end of the second core 103 is provided with a pressure cap, and the lower end of the pressure cap has a pressing edge. It is connected to the upper end of the second core 103 by an axially arranged pressure cap bolt. The pressure cap is fixed to the upper end of the first core 102 by the pressure cap bolt, thereby realizing the axial fixed assembly of the riser tube 80. Specifically, the vertical section of the stem tube 80 is fixedly mounted on the second core 103, and the first oil pipe 701 and the second oil pipe 702 can be hidden inside the cavity of the stem tube 80 to achieve hidden mounting of the oil pipes. Furthermore, the first oil pipe 701 and the second oil pipe 702 can be run through the cavity of the stem tube 80 and extend near the brake lever or directly connect to the brake lever to achieve fully hidden routing of the oil pipes. The oil pipes have a good protection effect and improve the aesthetics of the frame mounting.

[0088] In summary, the rotary oil-operated head structure provided in Embodiment 1 of this invention achieves concealed assembly of the oil pipes when mounting the bicycle, ensuring smooth brake oil flow. When the bicycle turns, the rotation of the main core component 10 drives the rotation of the front fork and front wheel to achieve the steering function. The third oil pipe 703, which runs inside the bicycle frame, achieves fully concealed assembly within the bicycle frame. Furthermore, the third oil pipe 703 can rotate with the steering without twisting or damaging the oil pipe. The rotary component 40 is movably sleeved on the main core component 10, so the fourth oil pipe 704 connected to the second oil outlet 403 on the rotary component 40 will not twist or damage the oil pipe with the steering. There is no need to reserve an exposed steering length for the fourth oil pipe 704, allowing for direct connection to the front brake pump with the shortest possible length, improving the aesthetics of the mounting and avoiding damage from exposed oil pipes.

The third oil pipe 703 runs inside the bicycle frame and extends near the rear brake down pump to connect to the rear brake down pump, thus achieving a fully concealed assembly of the third oil pipe 703; the second oil outlet 403 is close to the front wheel of the bicycle frame, and the fourth oil pipe 704 can be directly close to the front brake down pump at the front wheel of the bicycle frame, thereby minimizing the exposure of the fourth oil pipe 704 and achieving a concealed assembly;

[0095] When the rear brake is applied, the upper pump of the rear brake works to input oil through the second oil pipe 702 into the second oil inlet 205, and then the oil is output to the lower pump of the rear brake through the third oil pipe 703, thus achieving hydraulic braking. When the front brake is applied, the upper pump of the front brake works to input oil through the first oil pipe 701 into the first oil inlet, and then the oil is output to the lower pump of the front brake through the first annular groove 104 and then to the fourth oil pipe 704, thus achieving hydraulic braking.

[0096] When the bicycle turns, the handlebars drive the main core component 10 and the fork connected to the main core component 10 to rotate inside the tube body component 50 to achieve the steering function. The third oil pipe 703 runs through the tube body component 50 into the bicycle frame for fully concealed assembly. The third oil pipe 703 can rotate with the steering without causing the oil pipe to twist and be damaged. The rotating component 40 is movably sleeved on the main core component 10. Therefore, the fourth oil pipe 704 connected to the second oil outlet 403 on the rotating component 40 will not rotate with the steering and cause the oil pipe to twist and be damaged. There is no need to reserve an exposed steering length for the oil pipe. It can be concealed and assembled internally, improving the aesthetics of the vehicle and avoiding damage to the exposed oil pipe.

[0097] Meanwhile, in this embodiment, referring to Figures 4 to 6, further optimizations were made to the external leakage part of the oil outlet. A third oil pipe 703 extending axially along the outer wall of the rotating part 40 is connected to the first oil outlet through a movable oil plug. Parts of the movable oil plug and the third oil pipe 703 are hidden and assembled in the oil pipe chamber 501 opened on the side wall of the pipe body part 50.

[0098] Referring again to Figures 4-6, in an optional embodiment, the rotating member 40 further includes:

[0099] The step 402 is located in the middle of the axial inner wall of the rotating sleeve 401 and is positioned at the first annular groove 104 after assembly. The first groove 4021 and the second groove 4022 are formed sequentially from the middle to the sides of the axial inner wall of the rotating sleeve 401. The second oil outlet 403 is located in the middle of the step 402.

[0100] Two rotary sealing rings 404 are respectively assembled in the first groove 4021 and sleeved on the annular outer wall of the first core 102 to prevent oil leakage in the first annular groove 104;

[0101] Two bearings 405 are respectively assembled in the second slot 4022, and their inner rings are tightly fitted with the first core 102 to maintain the rotational assembly of the rotating component 40 on the main core 10; in this embodiment, the bearings 405 are deep groove ball bearings. Further, referring to Figures 5 and 6, after the two bearings 405 are assembled on opposite sides, they are pressed together and the rotary sealing ring 404 is axially positioned to seal the second oil passage 101.

[0102] In the above embodiment, the setting of the rotary sealing ring 404 effectively ensures the sealing of the annular oil circuit, prevents oil leakage and avoids dust entry. At the same time, the setting of the bearing 405 also reduces the rotational friction of the rotary component 40 on the main core component 10, ensuring smooth steering and not damaging the oil circuit.

[0103] Referring again to Figures 4-6, in this embodiment, the locking element includes:

[0104] The first locking member 20 is sleeved on the second core 103 and limited by the first protruding ring 105, and the outer edge of the first locking member 20 abuts against the edge of the first end of the tube body 50;

[0105] The second locking member 60 is assembled to the second end of the tube body 50 and threadedly assembled to the second end of the second core 103 to cooperate with the first locking member 20 to axially position the main core 10 and the rotating member 40; wherein, the second locking member 60 specifically includes:

[0106] The first nut 601 is threadedly fitted onto the second core 103 to cooperate with the first locking member 20 to axially position the rotating member 40.

[0107] The first locking sleeve 602 has its first end assembled to the free end of the second core 103, and its second end integrally formed with a step-shaped first annular protrusion 6021;

[0108] A locking screw hole 6022 is formed on the side wall of the first locking sleeve 602 to cooperate with the locking bolt assembled therein to fix the assembly position of the first locking sleeve 602;

[0109] The snap-fit ​​groove 603 is opened at the second end of the tube body 50 and forms a snap-fit ​​structure with the first annular protrusion 6021.

[0110] In the above embodiment, during assembly, the third oil pipe 703 is first threaded through the bicycle frame, then the first locking member 20 is installed at the upper end of the pipe body 50, and the first core 102 of the main core member 10 is inserted.

[0111] Subsequently, the rotating part 40, the first nut part 601, and the first locking sleeve 602 are assembled in sequence. The first annular protrusion 6021 at the second end of the first locking sleeve 602 abuts against the snap-edge groove 603 at the second end of the pipe body part 50. The assembly position of the first locking sleeve 602 is fixed by the locking bolt, thus completing the assembly of the main body.

[0112] Subsequently, the fourth oil pipe 704 is connected to the second oil outlet 403, the third oil pipe 703 is connected to the first oil outlet, the first oil pipe 701 is connected to the first oil inlet, and the second oil pipe 702 is connected to the second oil inlet, thus completing the oil circuit connection.

[0113] Furthermore, in this embodiment, a riser tube 80 is also included. The riser tube 80 is hollow inside, and one end of it is fitted onto the first core 102 to conceal the assembly of the first oil pipe 701 and the second oil pipe 702. Furthermore, the first end of the second core 103 is provided with a pressure cap, and the lower end of the pressure cap has a pressing edge. It is connected to the upper end of the second core 103 by an axially arranged pressure cap bolt. The pressure cap is fixed to the upper end of the first core 102 by the pressure cap bolt, thereby realizing the axial fixed assembly of the riser tube 80. Specifically, the vertical section of the stem tube 80 is fixedly mounted on the second core 103, and the first oil pipe 701 and the second oil pipe 702 can be hidden inside the cavity of the stem tube 80 to achieve hidden mounting of the oil pipes. Furthermore, the first oil pipe 701 and the second oil pipe 702 can be run through the cavity of the stem tube 80 and extend near the brake lever or directly connect to the brake lever to achieve fully hidden routing of the oil pipes. The oil pipes have a good protection effect and improve the aesthetics of the frame mounting.

[0114] In summary, the rotary oil-operated head structure provided in Embodiment 2 of the present invention achieves concealed assembly of the oil pipes when mounting the bicycle, ensuring smooth brake oil flow. When the bicycle turns, the rotation of the main core component 10 drives the rotation of the front fork and front wheel to achieve the steering function. The third oil pipe 703, which runs inside the bicycle frame, achieves fully concealed assembly within the bicycle frame. Furthermore, the third oil pipe 703 can rotate with the steering without twisting or damaging the oil pipe. The rotary component 40 is movably sleeved on the main core component 10, so the fourth oil pipe 704 connected to the second oil outlet 403 on the rotary component 40 will not twist or damage the oil pipe with the steering. There is no need to reserve an exposed steering length for the fourth oil pipe 704, allowing for direct connection to the front brake pump with the shortest possible length, improving the aesthetics of the mounting and avoiding damage from exposed oil pipes.

It is understood that quick-connect couplings can be pre-installed on the oil pipes to facilitate rapid connection. These quick-connect couplings are existing technology and were obtained by those skilled in the art from public disclosures. It is understood that this exemplary embodiment uses the quick-connect structure of the oil pipe disclosed in Chinese Patent ZL202411928412.1, which will not be described in detail here. The third oil pipe 703 runs inside the bicycle frame and extends near the rear brake down pump to connect to the rear brake down pump, thus achieving a fully concealed assembly of the third oil pipe 703; the second oil outlet 403 is close to the front wheel of the bicycle frame, and the fourth oil pipe 704 can be directly close to the front brake down pump at the front wheel of the bicycle frame, thereby minimizing the exposure of the fourth oil pipe 704 and achieving a concealed assembly;

[0121] When the rear brake is applied, the upper pump of the rear brake works to input oil through the second oil pipe 702 into the second oil inlet 205, and then the oil is output to the lower pump of the rear brake through the third oil pipe 703, thus achieving hydraulic braking. When the front brake is applied, the upper pump of the front brake works to input oil through the first oil pipe 701 into the first oil inlet, and then the oil is output to the lower pump of the front brake through the first annular groove 104 and then to the fourth oil pipe 704, thus achieving hydraulic braking.

[0122] When the bicycle turns, the handlebars drive the main core component 10 and the fork connected to the main core component 10 to rotate inside the tube body component 50 to achieve the steering function. The third oil pipe 703 runs through the tube body component 50 into the bicycle frame for fully concealed assembly. The third oil pipe 703 can rotate with the steering without causing the oil pipe to twist and be damaged. The rotating component 40 is movably sleeved on the main core component 10. Therefore, the fourth oil pipe 704 connected to the second oil outlet 403 on the rotating component 40 will not rotate with the steering and cause the oil pipe to twist and be damaged. There is no need to reserve an exposed steering length for the oil pipe. It can be concealed and assembled internally, improving the aesthetics of the vehicle and avoiding damage to the exposed oil pipe.

[0123] Referring again to Figures 7-9, in an optional embodiment, the rotating member 40 further includes:

[0124] The step 402 is located in the middle of the axial inner wall of the rotating sleeve 401 and is positioned at the first annular groove 104 after assembly.

[0126] Two bearings 405 are respectively assembled in the second slot 4022, and their inner rings are tightly fitted with the first core 102 to maintain the rotational assembly of the rotating component 40 on the main core 10. In this embodiment, the bearings 405 are deep groove ball bearings. Further, referring to Figures 8 and 9, after the two bearings 405 are assembled on opposite sides, they are pressed together and the rotary sealing ring 404 is axially positioned to seal the second oil passage 101.

[0127] Referring again to Figures 7-9, in this embodiment, the first core 102 includes:

There are at least three annular sealing grooves 1027, which are respectively formed on the inner wall of the outer core sleeve 1024 at the outer edge position corresponding to the second annular groove 1022, the position between the second annular groove 1022 and the third annular groove 1023, and the outer edge position of the third annular groove 1023.

[0137] The outer core sleeve 1024 is assembled and then abuts against the second end of the assembly step 1025. The pressing edge is assembled and then tightens the tensioning ring 302 to axially position the outer core sleeve 1024.

[0138] In the above embodiment, the O-ring and rotary seal 404 effectively ensure the sealing of the three annular oil passages, preventing oil leakage and dust ingress. Meanwhile, the ball bearing 405 reduces the rotational friction of the rotary component 40 on the main core component 10, ensuring smooth steering without damaging the oil passages.

[0139] Referring again to Figures 7-10, the locking element 60 includes:

[0140] The second headset assembly 608 is provided with a headset bolt 609 for adjusting the inner diameter of the second headset assembly 608. The tube body 50 is a fork riser tube, which is sleeved on the second end of the second core 103 and pressed tightly by the outside of the second headset assembly 608 to fix it.

[0141] The second bowl assembly 608, after assembly, abuts against the lower edge of the second convex ring 106 to limit axial movement.

[0142] In the above embodiment, during assembly, the third oil pipe 703 is first threaded through the bicycle frame and then connected to the first oil outlet. The fourth oil pipe 704 is connected to the second oil outlet 403. Subsequently, the fourth oil pipe 704 can extend directly along the outer wall of the front fork tube and connect to the front brake down pump, or the third oil pipe 703 can be threaded into the bicycle front fork, and then the second end of the third oil pipe 703 can be threaded out from near the front brake down pump and connected to the front brake down pump.

Further, in this embodiment, the vertical section of the riser tube 80 is assembled onto the second core 103, and then a tensioning ring 302 is sequentially inserted into the tensioning assembly groove 301. The pressure cap 303 is assembled and connected to the upper end of the second core 103 by the axially arranged pressure cap bolt, thereby achieving the axial fixed assembly of the riser tube 80 while tensioning the outer core sleeve 1024. Specifically, the vertical section of the stem tube 80 is fixedly mounted on the second core 103, and the first oil pipe 701 and the second oil pipe 702 can be hidden inside the cavity of the stem tube 80 to achieve hidden mounting of the oil pipes.

The oil pipes have a good protection effect and improve the aesthetics of the frame mounting.

[0146] Example 4

[0147] Embodiment 4 of the present invention also provides a rotating oil-passing head structure, which differs from Embodiments 1 to 3 in that, referring to Figures 5 and 6, the second oil passage 101 is composed of a first oil section 1011 and a second oil section 1012 connected in a straight line, and a second oil seal 1014 is provided between the first oil section 1011 and the second oil section 1012, and a first oil seal 1013 is provided at the opening of the second oil section 1012;

[0148] The first oil section 1011 connects the first annular groove 101 and the second oil inlet, and the second oil section 1012 connects the first oil inlet and the first oil passage 100.

[0149] In the above embodiment, to facilitate drilling and ensure smooth operation of the first oil passage 100 and the second oil passage 101, a segmented structure is designed for the second oil passage 101. The first oil section 1011 is connected to the first annular groove 104 and the second oil inlet by the sealing of the second oil seal 1014. The second oil section 1012 is connected to the first oil passage 100 by the sealing of the first oil seal 1013 and the second oil seal 1014, combined with the drilling of the first oil inlet, forming a relay oil passage, thereby connecting the first oil inlet and the second oil outlet.

[0150] This effectively reduces the difficulty of machining the oil passages on the main core component 10 and ensures smooth oil flow.

[0151] Example 5

[0152] Embodiment 5 of the present invention also provides a rotating oil-passing head structure, which differs from Embodiments 1 to 4 in that, referring to Figures 2 to 3, the first core 102 includes a first core segment 1028 and a second core segment 1029. The first core segment 1028 and the second core segment 1029 are axially arranged and fixed to the first core 102 by a plurality of long pins 1020.

[0153] In the above embodiment, in order to facilitate the drilling and processing of the first oil passage 100 and the second oil passage 101 and ensure smooth oil passage, a three-section structure of the main core 10 is designed. The second core 103 is divided into the first core segment 1028 and the second core segment 1029, and fixed to the first core 102 by a number of long pins 1020. Therefore, the holes and oil passages on the first core segment 1028, the second core segment 1029 and the first core 102 can be drilled separately. During assembly, the oil passages can be connected, which effectively reduces the difficulty of processing the oil passages on the main core 10 and ensures smooth oil passage.

[0154] In an optional embodiment, referring to Figures 5-6, the first protruding ring 105 can also be machined separately and then fixedly assembled onto the main core 10 by threads or pins, so as to further reduce the machining difficulty and improve the machining efficiency.

[0155] In another alternative embodiment, the connection method of the oil pipes can also be changed. The first oil inlet is connected to the rear brake upper pump through the first oil pipe 701; the second oil inlet is connected to the front brake upper pump through the second oil pipe 702; the first oil outlet is connected to the front brake lower pump through the third oil pipe 703; and the second oil outlet 403 is connected to the rear brake lower pump through the fourth oil pipe 704. The purpose of this is to allow the third oil pipe 703, which runs through the pipe body 50, to be hidden and run directly through the bicycle fork. Then, the second end of the third oil pipe 703 passes out from near the front brake lower pump and connects to the front brake lower pump. The fourth oil pipe 704, with only a small part of the oil pipe exposed, can be directly inserted into the bicycle frame nearby, with only a small part of the oil pipe exposed, thus maintaining the hidden assembly effect of the oil pipes.

[0156] Example 6

[0157] Embodiment 6 of the present invention provides a bicycle, including a rotary oil-cooled front end structure of any one of Embodiments 1 to 5.

[0158] Other undescribed structures are described in Examples 1-5.

[0159] In summary, the rotary hydraulic head structure and bicycle provided in Embodiment 6 of this invention achieve concealed assembly of the hydraulic pipes during bicycle mounting, ensuring smooth braking hydraulic circuit. When the bicycle turns, the rotation of the main core component 10 drives the rotation of the front fork and front wheel to achieve the steering function. The third hydraulic pipe 703, which runs inside the bicycle frame, achieves fully concealed assembly within the bicycle frame. The third hydraulic pipe 703 can rotate with the steering without twisting or damaging the hydraulic pipe. The rotary component 40 is movably sleeved on the main core component 10, so the fourth hydraulic pipe 704 connected to the second oil outlet 403 on the rotary component 40 will not twist or damage the hydraulic pipe with the steering. There is no need to reserve an exposed steering length for the fourth hydraulic pipe 704, allowing for direct connection to the front brake pump with the shortest possible length, improving the aesthetics of the mounting and avoiding damage from exposed hydraulic pipes. At the same time, through structural optimization, the machining difficulty of the hydraulic passages on the main core component 10 is greatly reduced, ensuring smooth hydraulic circuit.
