Description

Technical Field

[0001] This invention relates to a positioning device, and more particularly to a cable positioning device in the field of bicycles. Prior Technology

[0002] In recent years, bicycles have adopted internal cable routing designs to improve overall aesthetics and durability. One common headband design involves running the cable through the headband and hiding it inside the handlebar stem and head tube before extending to the fork tube. This effectively improves cable protection and reduces friction and the impact of the external environment.

[0003] The applicant previously filed a patent application in my country, TW I838871, which disclosed a waterproof cable routing structure inside a bicycle headband. This structure includes a headband assembly installed between the outer side of a fork tube and the upper inner side of a head tube. The headband assembly is axially mounted with a bearing, a bearing seat, and a cable tie. A waterproof component and a top cover are stacked on the cable tie. The waterproof component is a closed ring with a cable hole that communicates with the bearing seat for the cable to pass through. Therefore, the cable passes through the inner hole of the inner flange, effectively preventing water or mud from seeping into the head tube, thus improving the waterproof and dustproof functions.

[0004] When the aforementioned technologies are used for a long time or damaged by collisions with external objects, they are very likely to suffer wear and breakage due to frictional forces, and may also cause deformation and internal stress accumulation due to uneven or excessive force concentration in a specific area. This could lead to the collapse, cracking, breakage or permanent deformation of any of the aforementioned components, affecting the overall stability and service life. Summary of the Invention

[0005] The main objective of this invention is to provide an internal wiring positioning device that can be installed quickly, increases the support structure to distribute pressure, and improves the stability and durability of the overall structure.

[0006] To achieve the above objectives, the present invention provides an internal wiring positioning device, comprising:

[0007] A top cover has a bottom and at least one through hole penetrating the top cover, the bottom being provided with a plurality of protrusions;

[0008] A waterproof component has a top surface and a bottom surface opposite to the top surface. The top surface has at least one threading portion, a plurality of slots, and a plurality of ribs. The threading portion is for engaging with a through hole and has a plurality of wire holes for wire to pass through. The slots and ribs are spaced apart and are for accommodating protrusions. The ribs are for engaging between the protrusions. The bottom surface of the waterproof component has a plurality of bottom support portions, one end of each bottom support portion is connected to the bottom surface, and the other end of some bottom support portions protrudes out of a positioning body.

[0009] A clamping member has an inner annular surface, an outer annular surface opposite to the inner annular surface, and a notch that passes through the inner annular surface and the outer annular surface; and

[0010] A base has an inner ring wall, which surrounds a third through hole, two receiving holes connected to the third through hole, a rib and two recessed holes. The third through hole is for receiving the clamping member. The rib is spaced between the two recessed holes. The rib is for receiving the notch. The two receiving holes are for receiving the positioning bodies.

[0011] Preferably, a recessed area is formed between the bottom support and the other side of the positioning body, and the recessed area is used for the base to abut against.

[0012] Preferably, the waterproof component has a ring portion that connects to the ribs.

[0013] Preferably, the clamping member has a top surface for contacting any or a combination of the ring, the ribs, the slots, the protrusions, etc.

[0014] Preferably, the inner wall of the ring is provided with a plurality of conical surfaces, which are provided for the outer ring surface to abut against.

[0015] Preferably, the conical surface also has a texture, which is selected from straight lines, curves, horizontal lines, cross lines, irregular lines and combinations thereof.

[0016] Preferably, the length of the rib extends beyond the notch toward the inner annular surface.

[0017] Preferably, one side of the inner wall of the ring surrounding the two receiving holes is an arc surface with an R-angle.

[0018] Preferably, a portion of the curved surface is provided for contact and abutment with the recessed area.

[0019] Preferably, the positioning body extends out of the base.

[0020] Therefore, the present invention utilizes the interlocking of protrusions, slots, and ribs, and the matching shape of the threaded portion and the through hole, to ensure a stable combination between the waterproof component and the top cover. Simultaneously, the wire is routed into the head tube via an internal wiring structure. Furthermore, the bottom support portions of the waterproof component provide even support to the base, dispersing pressure and reducing localized stress concentration. Some of the bottom support portions also have positioning elements that abut against opposite ends of the receiving hole, allowing the waterproof component to connect with the base more quickly. Through this combined application, the risk of component collapse during compression is effectively reduced, improving the overall structural stability and durability.

[0033] Please refer to Figures 1 to 9. The present invention includes a top cover 1, a waterproof component 2, a clamping component 3, and a base 4. The base 4 and the clamping component 3 are arranged in the same axial direction. The top cover 1 and the waterproof component 2 are arranged in a corresponding combination, and the waterproof component 2 and the base 4 are assembled abutting against each other. This prevents any component from collapsing when the user needs to press the components together, and allows a cable (not shown) to pass through it, forming an internal cable routing. In addition, after assembling the above components, the present invention can be combined with a commercially available headset. The commercially available headset has a conventional structure and will not be described in detail here. As shown in Figure 8, after the present invention is combined with the headset, it can be combined with a fork tube 8, as shown in Figure 10.

[0034] Please refer to Figures 3, 4, and 9. The top cover 1 is used to cover the waterproof component 2. The top cover 1 is a hollow ring. The top cover 1 has a first through hole 11 that penetrates the top cover 1, through which the fork tube 8 passes. The top cover 1 also has at least one through hole 12 that penetrates the top cover 1. The area of ​​the through hole 12 is smaller than that of the first through hole 11. The through hole 12 and the first through hole 11 are spaced apart by a distance. In this embodiment, there are two through holes 12, which are symmetrically arranged. The top cover 1 also has... The device has a bottom 13, which faces the waterproof component 2 when the top cover 1 is assembled with the waterproof component 2. The bottom 13 is provided with a plurality of protrusions 131, which protrude toward the waterproof component 2. The protrusions 131 are arranged around the first through hole 11 and are arranged at equal intervals. In this embodiment, the protrusions 131 are elongated and there are six of them, but this is not a limitation. In one embodiment, the protrusions 131 are arranged at unequal intervals in the first through hole 11 of the bottom 13.

[0035] Please refer to Figures 3 to 5 and Figure 9. The waterproof component 2 has a top surface 21, a bottom surface 22 opposite to the top surface 21, and a second through hole 23 penetrating the top surface 21 and the bottom surface 22. The second through hole 23 communicates with the first through hole 11 during assembly. The second through hole 23 allows the fork tube 8 to pass through. The top surface 21 has at least one protruding threading portion 24, which is shaped to match the through hole 12. The threading portion 24 is assembled with the through hole 12 through a concave-convex fit, thereby making the waterproof component 2 and the upper cover 1 group firmly connected. The threading portion 24 has a plurality of wire holes 241, which are closed and can be opened when needed by the user. The wire holes 241 are cut or slit to make them open and extend to the bottom surface 22, allowing the wire to be inserted through the wire holes 241 and to move and extend. At the same time, the wire is fixed in the wire holes 241. In this embodiment, the entire waterproof component 2 is made of elastic material, and the diameter of the wire holes 241 is smaller than the diameter of the wire, so that the wire holes 241 can fit the wire, thereby protecting the wire and preventing the entry of foreign objects such as moisture or dust. In one embodiment, only the threading part 24 is made of elastic material, so that the wire holes 241 can be used for the wire to pass through. The waterproof component 2 has a ring portion 29, a plurality of slots 25, and a plurality of ribs 26 at one end of the top surface 21. The ring portion 29 is arranged around the second through hole 23. The slots 25 and ribs 26 are arranged at intervals. The ring portion 29 connects to the ribs 26. Furthermore, the slots 25 are located between the ring portion 29 and the second through hole 23. One end of each rib 26 is connected to the ring portion 29. A rib 26 is provided between the holes 25. The holes 25 are for receiving the protrusions 131. The ribs 26 are for engaging between the protrusions 131. The ring portion 29 is for fitting against the ring wall of the fork tube 8, thereby achieving a tight fit, waterproofing and dustproofing. As shown in Figures 10 and 11, the shapes of the holes 25, the ribs 26 and the protrusions 131 are matched, thereby making the waterproof component 2 and the top cover 1 securely combined.

[0036] Please refer to Figures 3 to 5. It is worth noting that, in order to better highlight the features of this case, Figure 5 hides the clamping member 3. The bottom surface 22 of the waterproof member 2 has a plurality of bottom support portions 27. These bottom support portions 27 are generally block-shaped. One end of each bottom support portion 27 is connected to the bottom surface 22, and the other end of each bottom support portion 27 protrudes a positioning body 28. One side of the positioning body 28 is connected to the bottom surface 22, and a recessed area 271 is formed between the bottom support portion 27 and the other side of the positioning body 28. The recessed area 271 is provided for the base 4 to abut against. It is worth noting that in this embodiment, there are five base support parts 27, four of which have the positioning body 28, and the four base support parts 27 are symmetrically arranged with the second through hole 23 as the center. The other base support part 27 does not have the positioning body 28. The positioning body 28 is used to position the base 4 in the correct position, providing the user with the convenience of quick alignment. The base support parts 27 are used to distribute the stress concentration when the user applies pressure to assemble the waterproof component 2 and the top cover 1. By distributing the pressure evenly through the base support parts 27, a more effective distribution of pressure is achieved, avoiding stress concentration that could cause damage, partial damage, or disintegration of the top cover 1, the waterproof component 2, the clamping component 3, or the base 4 due to weak assembly strength.

[0037] Please refer to Figures 3, 4, and 9. The clamping member 3 is annular. The clamping member 3 has an inner ring surface 31, an outer ring surface 32 opposite to the inner ring surface 31, and a notch 33. The notch 33 passes through the inner ring surface 31 and the outer ring surface 32. The notch 33 is used for compression deformation. The inner ring surface 31 is used to clamp the fork tube 8, and the outer ring surface 32 is used to abut against the base 4. The clamping member 3 also has a first diameter R1 and a second diameter R2 opposite to each other. When assembled, the first diameter R1 is closer to the waterproof member 2 than the second diameter R2. The first diameter R1 is larger than the second diameter R2, so that the thickness of the clamping member 3 gradually decreases from the first diameter R1 to the second diameter R2, and the shape of the clamping member 3 is generally conical from the first diameter R1 to the second diameter R2. As shown in Figure 3, the clamping member 3 also has a top surface 34. One side of the top surface 34 is connected to the inner ring surface 31, and the other side of the top surface 34 is connected to the outer ring surface 32. The notch 33 penetrates the top surface 34. When assembled, the top surface 34 faces the waterproof member 2. The top surface 34 is used to contact any or a combination of the ring portion 29, the ribs 26, the slots 25, and the protrusions 131. Preferably, part of the top surface 34 is used for the ring portion 29 to abut, part of the top surface 34 is used for the ribs 26 to abut, and part of the top surface 34 contacts the protrusions 131 through the slots 25. In one embodiment, the protrusions 131 protrude from the slots 25, and the top surface 34 only abuts against the protrusions 131, but this is not a limitation.

[0038] Please refer to Figures 2 to 9. The base 4 has an inner ring wall 41. The inner ring wall 41 surrounds and forms a third through hole 42, two receiving holes 43 communicating with the third through hole 42, a protruding rib 44, and two concave holes 45. The third through hole 42 is used to receive the clamping member 3 and the fork tube 8. The two receiving holes 43 are located on both sides of the clamping member 3 during assembly. The two concave holes 45 are spaced apart by the protruding rib 44, which can receive the notch 33. The inner ring wall 41 is also provided with a plurality of conical surfaces 46, which are used for the clamping member 3 to abut against. In this embodiment, there are a total of three conical surfaces 46, two of which are... Conical surfaces 46 are located on both sides of the rib 44, with one remaining conical surface 46 facing the rib 44. When the user applies pressure or there is an external force, the outer ring surface 32 and the three conical surfaces 46 are locked together, preventing the clamping member 3 from leaving the third through hole 42. At the same time, the pressure is distributed by the three conical surfaces 46. In this embodiment, the conical surfaces 46 also have a texture (not shown in the figure). The texture is selected from straight lines, curves, horizontal lines, cross lines, irregular lines and combinations thereof, thereby increasing the friction between the outer ring surface 32 and the conical surfaces 46, and making the clamping member 3 more securely connected to the base 4.

[0039] Please refer to Figures 5 to 7. The receiving hole 43 of the base 4 is used to receive the positioning body 28. As shown in Figure 2, the recessed area 271 is used for the base 4 to abut. In this embodiment, every two positioning bodies 28 are received in the same receiving hole 43, and the two positioning bodies 28 abut against the opposite ends of the receiving hole 43, so that the waterproof component 2 can be combined with the base 4 more quickly. At the same time, the base 4 is in close contact with the bottom support 27. Please refer to Figures 2, 6 and 7. This not only prevents the waterproof component 2, the top cover 1, the clamping member 3 and the base 4 from being damaged or detached due to excessive compression during use or assembly, but also effectively disperses pressure, ensures overall stability, and further improves waterproof performance and durability. Please refer to Figure 5. One side of the inner wall 41 of the ring surrounding the two receiving holes 43 is an arc surface 411 with a radius R. When the wire is inserted, the arc surface 411 can effectively reduce the risk of the wire being cut and improve the safety of use. At the same time, part of the arc surface 411 is also used for the recessed area 271 to contact and abut. In addition, the arc surface 411 is only located on one side of the inner wall 41 of the ring, ensuring that the other side of the inner wall 41 of the ring remains flat to meet the requirement of stable installation.

[0040] It is worth noting that the positioning body 28 can extend and protrude from the base 4. When it is installed on the headband, the inner ring wall of the headband has two stops. The positioning body 28 can stop the handlebars at a specific rotation angle by abutting against and stopping on the two stops, thereby limiting the turning range to a specific range and providing the user with safety and control of the bicycle.

[0041] The two concave holes 45 and the convex ribs 44 face one of the conical surfaces 46. The convex ribs 44 and the two concave holes 45 ensure that the clamping member 3 is in the correct position and limit the range of movement of the clamping member 3. Thus, the two concave holes 45 and the convex ribs 44 simultaneously have the functions of fixing the clamping member 3 and positioning the clamping member 3. The two concave holes 45 can effectively prevent the clamping member 3 from shifting during use, ensuring that the clamping member 3 remains in the predetermined position, thereby improving the stability and durability of the overall structure. In the prior art, when the clamping member 3 rotates, it often clamps the wire, affecting normal operation and even causing damage or jamming to the wire. Therefore, the present invention ensures that the clamping member 3 can operate stably in various environmental applications, such as under pressure, long-term use, or displacement due to vibration during use, through the two concave holes 45 and the convex ribs 44, thereby improving safety and reliability. In another embodiment, the rib 44 extends beyond the notch 33 towards the inner annular surface 31. During assembly, the rib 44 can contact the fork tube 8, increasing overall stability. It is worth noting that when the clamping member 3 is inserted into the third through hole 42 of the base 4, the outer annular surface 32 abuts against the conical surface 46, and the notch 33 is fitted around the rib 44. There is still a gap between the notch 33 and the rib 44, which provides the deformation space required by the clamping member 3, as shown in Figures 2 and 6.
