Generally speaking, one end of the pipeline is connected to a bicycle controller (such as a transmission controller, seat height controller, brake lever, etc.), and the other end of the pipeline is connected to a bicycle element (such as a transmission, brake, telescopic seatpost). Etc.) connection. Among them, the routing method of FIG. 20 is that the pipeline L passes through the first line hole 20a of the riser 2 into the accommodation space S of the riser 2, and then passes through the second line hole 20b to the outside of the riser 2, and This routing method is suitable for the entire line operation of the pipeline.

In the wiring method of FIG. 21, the pipeline L is penetrated from the first wire hole 20a of the riser 2 to the accommodation space S of the riser 2, and the distance between the top cover 23 and the first clamp 21 is used to make the pipeline L through Then, through the groove 241 on the outer peripheral wall of the pressing element 24, the pipeline L can enter the steering tube 52 of the front fork 5. This routing method is suitable for the hidden line operation of the front brake line.

The wiring method of FIG. 22 is different from that of FIG. 21 in that the pipeline L is penetrated into the accommodation space S of the vertical pipe 2 through the second wire hole 20b of the vertical pipe 2, and the top cover 23 and the first clamp are also used in the following. The distance between the pieces 21 allows the pipeline L to pass, and then enters the steering tube 52 of the front fork 5 through the slot 241 on the outer peripheral wall of the pressing element 24. This routing method is also suitable for the hidden line operation of the front brake line. .

In the wiring method of FIG. 23, the pipeline L passes through the first line hole 20a of the riser 2 to the accommodation space S of the riser 2, and then passes through the communication hole 217 of the riser 2 and the second hole 322 of the gasket 3. And the through hole 412 of the head pipe 41 enters the head pipe 41, and then enters the lower pipe 43 of the frame 4 through the conduit 44 in the frame 4. The design of the duct 44 is to fix the position of the pipeline L in the frame 4 so as to prevent the pipeline L from shaking during riding and colliding with the frame 4 or being sheared when turning. In addition to reducing noise, it can also increase The life of pipeline L. Of course, in actual implementation, if the diameter of the pipeline L is relatively large, it can also directly enter the lower tube 43 of the frame 4 without passing through the conduit 44. This wiring method is suitable for the hidden line operation of the front and rear transmission control lines, rear brake lines or seat tube control lines.

The wiring method of FIG. 24 is different from that of FIG. 23 in that the pipeline L is penetrated into the accommodation space S of the vertical pipe 2 through the second wire hole 20b of the vertical pipe 2 and subsequently passes through the communication hole 217 of the vertical pipe 2 as well. The second perforation 322 of the gasket 3 and the through hole 412 of the head tube 41 enter the head tube 41, and then enter the lower tube 43 of the frame 4 through the conduit 44 in the frame 4. Of course, in actual implementation, if the diameter of the pipeline L is relatively thick, it can also directly enter the lower pipe 43 of the frame 4 as described above. This wiring method is also suitable for the hidden line operation of the front and rear shift control lines, rear brake lines or seat tube control lines.

In addition, it must be noted that in addition to providing multiple wiring methods for users to choose freely through the aforementioned design, the communication hole 217 of the standpipe 2 and the second hole 322 of the gasket 3 The width of the through hole 412 of the head tube 41 and the arc-shaped design allow the user to control the steering of the vehicle head by manipulating the handlebar 1 so that the pipeline can be positioned in the communication hole 217, The perforations 322 and through holes 412 move slightly, and the arc design is more consistent with the swing amplitude, which can reduce the distortion and shear of the pipeline, and reduce the friction between the pipeline and the components. In order to be smooth and extend the life of the pipeline, it can also increase the safety of the user when riding. Of course, in other designs, the user can also design the connecting hole, the second perforation, and the through-hole according to the needs of different steering amplitudes. The center hole angle is not less than 45 degrees and not more than 135 degrees, and the largest hole. Width can also choose other widths not less than 3mm and not more than 30mm.

In addition, the communication hole 217 of the stand pipe 2, the second hole 322 of the gasket 3, and the through hole 412 of the head pipe 41 are respectively combined with the hole 216 of the stand pipe 2, the first hole 312 of the gasket 3, and the head pipe 41. The purpose of the through-hole 411 is to separate the pipeline from the steering tube 52 of the front fork 5 in different spaces, to prevent the pipeline from directly contacting the steering tube 52, and to prevent the pipeline from turning to the steering tube 52 when turning. The generation of friction can also achieve the effects of making the steering smoother, extending the life of the pipeline, and increasing the safety of the user when riding. Of course, before affecting the structural strength, it is mentioned that between the communication hole 217 and the coupling hole 216 of the stand pipe 2, between the second hole 322 and the first hole 312 of the gasket 3, and the through hole 412 and the top of the head pipe 41. A pitch of not less than 0.1 mm and not more than 30 mm can also be selected between the through holes 411 to achieve the same purpose.

In addition, the first stopper portion 414 of the head pipe 41 is arc-shaped, and the second stopper portion 53 on the front fork 5 is located in the first stopper portion 414 as shown in FIG. When the front steering is controlled to drive the front fork 5 to rotate, the second stop portion 53 will move along the first stop portion 414. When the user turns to a certain angle, the second stop portion 53 will abut the first stop The groove wall of the portion 414 makes it impossible for the user to increase the steering angle and prevents the user from oversteering, thereby achieving the effect of increasing riding safety. And if the user turns too much, Pulling the pipeline or pressing the pipeline against other head components will shorten the pipeline life. In other words, the aforementioned design to avoid excessive steering has the effect of extending the life of the pipeline.

It is worth mentioning that, in other designs, the user can also design the aforementioned first stopper into an arc with a center angle of not less than 45 degrees and not more than 135 degrees according to the requirements of different steering ranges, and the maximum groove width You can also choose other widths that are not less than 3mm and not more than 30mm, and you can get a better stopping effect by matching the second stopping part of the corresponding size. In addition to the aforementioned design, the user may also choose to provide a second stopper on the head tube and a first stopper on the front fork to achieve the same effect.

In addition, the design purpose of the gasket 3 made of different elastic coefficient materials is that the main function of the first part 31 is to combine with the vertical pipe 2 and the head pipe 41, and the use of a relatively hard material with a low elastic coefficient can ensure that The physical strength and service life meet requirements, and the main function of the second part 32 is to form a second perforation 322 through which the pipeline passes. To avoid the pipeline being prone to damage due to long-term contact and friction with hard objects, then Use materials with higher elastic coefficients to achieve the purpose of extending the service life of the pipeline.

It is worth mentioning that in order to achieve the above-mentioned effect, the aforementioned gasket 3 can also be manufactured by injection molding, that is, the gasket 3 is first made into the first part 31 having the first perforation 312, and then the injection molding technology is used to The second portion 32 covers the first portion 31 and forms a second perforation 322 to achieve the same purpose.

In addition, in addition to designing the second perforation of the gasket as an arc, as shown in FIG. 25, a plurality of second perforations 323 (three in this figure are taken as examples) can be designed on the gasket 3 "for each pipeline to pass through. And, for the convenience of pipeline installation, it is recommended that the hole diameter of the second perforation 323 is not less than 3mm and not more than 20mm.

In addition, it is worth mentioning that in addition to the above-mentioned pressing element 24 of FIG. 7, the pressing element used in this case can also use the structural design of the pressing element 24 ′ shown in FIG. 26. It also has a slot 241 'for the pipeline to pass through, and in order to achieve a better threading effect, the hole width of the slot 241' is recommended to be not less than 2mm and not more than 10mm.

Finally, it must be noted that the above are only the preferred and feasible embodiments of the present invention. For example, any equivalent changes made by applying the description of the creation and the scope of patent application should be included in the scope of the patent of the creation.
