Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a cable routing plug, guide assembly, guide structure, frame, and bicycle. Background Technology

[0002] Existing bicycles with internal cable routing typically have multiple holes drilled directly into the frame, allowing the cable harness to pass through these holes and be routed through the frame to achieve internal cable routing. However, since the inner tube diameter of the frame is usually much larger than the diameter of the cable harness, the cable harness is not well secured within the frame, and the cable harness tends to wobble and generate noise when the bicycle is ridden.

[0003] In addition, when the user turns the bicycle by maneuvering the handlebars, the wiring harnesses in the above-mentioned internal cable routing design will also be moved along with the handlebars. If the position of the internally routed wiring harnesses is not fixed, it may cause friction or shearing between the wiring harnesses and the inner wall of the frame, resulting in wear and breakage of the brake cables and shift cables. Furthermore, the friction between the wiring harnesses and the frame can also easily cause interference when turning, thus causing discomfort and safety hazards when riding. Utility Model Content

[0004] The purpose of this utility model is to provide a wire harness plug, guide assembly, guide structure, frame and bicycle for internal wiring, which makes the wire harness neatly routed inside the frame, less prone to shaking, less likely to impact the frame and generate noise, and will not interfere with the bicycle's steering.

[0005] To achieve the above objectives, this utility model discloses a wire guide plug for vehicle frame internal wiring, comprising a positioning member and a support member, wherein the support member and the positioning member are connected together. At least part of the support member is deformable, and through deformation, the support member abuts against the inner wall of the vehicle frame. The positioning member has a limiting hole for the wire harness to pass through. The deformation of the support member allows the wire guide plug to be installed inside the vehicle frame, enabling the support member to abut against the inner wall of the vehicle frame. The support member provides support for the positioning member, making the position of the positioning member relatively stable. The position of the limiting hole is also relatively stable, thus restricting the passage of the wire harness through the limiting hole, thereby ensuring the relative stability of the wire harness position.

[0006] Preferably, the support member and the positioning member are fixedly connected, with the support member connected to the outer periphery of the positioning member. The limiting hole is surrounded by the support member, which isolates the "wire harness passing through the limiting hole" from the "inner wall of the frame" to avoid impact, while also improving the stability of the support member against the inner wall of the frame.

[0007] Preferably, the support member is at least partially elastically deformable, and the outer edge of the elastically deformable support member abuts against the inner wall of the frame. The elastic deformation facilitates the insertion of the wire plug into the frame and allows the elastic rebound force to keep the outer edge of the support member abutting against the inner wall of the frame. This provides high support stability, allows for multiple uses, and is adaptable to frames with different bore diameters.

[0008] Preferably, the centerline of the positioning member is arranged along a first direction, and the limiting hole surrounds the centerline; the support member includes a deformable section, which extends relative to the positioning member from near to far and from inside to outside along the first direction. The fact that the deformable section extends relative to the positioning member from near to far and from inside to outside along the first direction generates an outward elastic force or a component of elastic force, resulting in strong rebound force, directional stability, and high support stability.

[0009] Preferably, the support member comprises several support units, which are arranged radially around the positioning member, with the ends of the support units suspended in the air. By having the suspended ends of the support units abut against the inner wall of the vehicle frame, the wire plug can better contact and abut against the inner wall of the vehicle frame, ensuring the stability of the wire plug position, ensuring the stability of the wiring harness position, and also facilitating the installation of the wire plug.

[0010] Preferably, one end of the support unit is fixedly connected to the edge of the positioning member. The support unit has strong elastic deformation force, which facilitates assembly and improves support stability.

[0011] Preferably, the suspended end of the support unit has a bent portion. By providing the bent portion, the buffering capacity (elasticity) of the wire plug is improved, and the assembly of the wire plug is also facilitated.

[0012] Preferably, 110°≤A≤170°, or 185°≤A≤225°. This facilitates the assembly of the wire plug.

[0013] Preferably, the ratio of the length of the support unit to the length of the bent portion is (1-10):1, ensuring that the bent portion functions effectively.

[0014] Preferably, the support member has an inclined section, which is inclined relative to the positioning member. This gives the wire plug a certain buffering capacity (elasticity). The wire plug can be designed to be slightly larger than the cross-section of the frame's inner cavity, so that the wire plug is placed in a slightly compressed state within the frame's inner cavity, making it less likely for the wire plug to slip and ensuring the stability of the wiring harness position. In addition, it also facilitates the assembly of the wire plug.

[0015] Preferably, the angle between the inclined section and the positioning element is B, where 90° < B ≤ 150°. This balances the length and elasticity requirements of the support element.

[0016] Preferably, the deformed section includes a frustum-shaped wall. This facilitates the processing of the wire plug and reduces costs.

[0017] Preferably, the frustum wall has a through groove running both inside and out. The groove improves elasticity.

[0018] Preferably, the deformable section includes an annular portion that is fixed around the positioning member, and the annular portion can be elastically bent and deformed along a first direction. After bending and deforming, the annular portion forms a frustum-like structure. After installation, the frustum-like structure generates an outward elastic force or a component of the elastic force to support and abut against the vehicle frame. The wire plug structure is simple and has low production cost.

[0019] This utility model also discloses a cable routing plug for a vehicle frame, including a positioning member and a support member, which are connected together. The support member is at least partially deformable and has an initial state and a deformed state. The deformed support member generates an elastic force, which is either from the inside out or has an inner-outer component. The positioning member has a limiting hole for the cable harness to pass through. The elastic force, whether from the inside out or having an inner-outer component, causes the outer edge of the support member to abut against the inner wall of the vehicle frame, resulting in high support stability.

[0020] This utility model also discloses a cable routing guide assembly within a vehicle frame, which includes the aforementioned cable routing wire plug within the vehicle frame. Depending on the actual application, one wire harness (at least one of the brake cable, gear cable, and oil cable) can be used with one wire plug, or one wire harness can be used with two or more wire plugs, etc., making it flexible, convenient, and easy to install.

[0021] This utility model also discloses a cable routing guide structure within a bicycle frame, comprising at least two sets of the aforementioned guide components. The guide components are disposed within the frame, and the outer edge of the cable plug abuts against the inner wall of the frame. The limiting holes of all cable plugs within the same guide component form a guide channel for the cable harness. Through this arrangement, the cable harness can be supported within the frame cavity by the cable plugs (the cable harness passes through the limiting holes, thus providing support), ensuring the cable harness's stable position and preventing collisions with the frame. By providing a guide channel for the cable harness within the frame cavity, its position can be limited, preventing it from swinging and colliding with the frame to generate noise. Furthermore, because the cable harness is restricted by the cable plugs, its position is relatively stable. With proper wiring during assembly, the cable harness does not interfere with bicycle steering, and the cable harness is also protected.

[0022] Preferably, the wire plug's shape is adapted to the cross-section of the vehicle frame's inner cavity. This adaptation ensures more even stress distribution across the wire plug, reduces its tendency to shift, and provides high positional stability, thereby guaranteeing the stability of the wire plug and the wiring harness.

[0023] This utility model also discloses a vehicle frame that adopts the above-mentioned internal wiring guide structure.

[0024] Preferably, the frame includes a frame body, a front fork, and a handlebar; the front fork has a vertical tube, and the cavity of the vertical tube communicates with the inner cavity of the front fork; the frame body has a bushing, a downtube, and a rear triangle connected in sequence, the vertical tube passes through the bushing and connects to the handlebar, and the vertical tube rotatably engages with the bushing, the cavity of the vertical tube communicates with the inner cavity of the handlebar; there is a cable routing gap between the outer wall of the vertical tube and the inner wall of the bushing, the handlebar has a cable harness positioning hole, and the cable routing gap communicates with the inner cavity of the handlebar through the cable harness positioning hole; wherein: at least one of the guide components is disposed in the front fork, and the cavity of the vertical tube communicates with the guide channel corresponding to the guide component; at least one of the guide components is disposed in the frame body, and the guide channel corresponding to the guide component communicates with the cable harness positioning hole through the cable routing gap. This ensures that the wiring harness is guided and limited in most of the larger spaces within the frame cavity. Within the handlebar and bushing movement areas, the wiring harness is constrained by the wiring harness positioning holes and various guide channels, allowing it to maintain a good position and not interfere with handlebar steering.

[0025] Preferably, there are four sets of guide components, namely a front brake guide component, a rear brake guide component, a mid-range shifter guide component, and a rear derailleur guide component; the front brake guide component includes a front brake cable plug, which is placed in the vertical tube; the rear brake guide component includes two first rear brake cable plugs and one second rear brake cable plug, with the first rear brake cable plug placed in the lower tube and the second rear brake cable plug placed in the rear triangle; the mid-range shifter guide component includes two mid-range shifter cable plugs, which are placed in the lower tube; the rear derailleur guide component includes two first rear derailleur cable plugs and one second rear derailleur cable plug, with the first rear derailleur cable plug placed in the lower tube and the second rear derailleur cable plug placed in the rear triangle; the first rear brake cable plug, the mid-range shifter cable plug, and the second rear derailleur cable plug are all corresponding to each other and integrated into one unit. Corresponding guide components can be provided for the front brake cable, rear brake cable, mid-range shifter cable, and rear derailleur cable, allowing the brake cable and derailleur cable to be well guided and positioned within the frame cavity.

[0026] Preferably, three wiring harness positioning holes are provided and spaced apart; or one wiring harness positioning hole is provided and is an elongated hole. This allows the wiring harness to be more concentrated at the bicycle's steering nodes, and the amount of movement of the wiring harness when the handlebars turn is smaller.

[0027] Preferably, the frame body, fork, and handlebars are all made of carbon fiber. The frame structure is strong and lightweight.

[0028] This utility model also discloses a bicycle using the above-described frame.

[0029] This utility model has the following beneficial effects:

[0030] This invention allows the wiring harness to be hidden in the frame, keeping the bicycle's outer surface neat and tidy. It also prevents the harness from colliding with the frame and causing noise during riding, guides the harness's direction, prevents it from interfering with the bicycle's steering, facilitates harness installation and protection, extends the harness's lifespan, and has excellent market potential.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Furthermore, in this case, the riding direction of the bicycle is considered the forward direction.

[0043] Example 1

[0044] like Figures 1-7 As shown, this embodiment discloses a bicycle with internal cable routing. The bicycle frame has four cable harnesses: a front brake cable 11, a rear brake cable 12, a mid-derailleur cable 13, and a rear derailleur cable 14. These cable harnesses are hidden inside the frame. The frame employs an internal cable routing guide structure, which includes four sets of internal cable routing guide assemblies placed within the frame. Each of the front brake cable 11, rear brake cable 12, mid-derailleur cable 13, and rear derailleur cable 14 corresponds to one set of internal cable routing guide assemblies, and is defined as the front brake guide assembly, rear brake guide assembly, mid-derailleur guide assembly, and rear derailleur guide assembly, respectively.

[0045] The frame includes a frame body 21, a front fork 22, and a handlebar 23, all of which are made of carbon fiber. The front fork 22 has a steerer tube 24, the cavity of which connects to the inner cavity of the fork 22. The frame body 21 has a bushing 25, a downtube 26, and a rear triangle 27 connected in sequence. The steerer tube 24 passes through the bushing 25 and connects to the handlebar 23, with the steerer tube 24 and bushing 25 rotatably engaging to ensure the handlebar 23 controls the rotation of the front fork 22. The steerer tube 24 connects to the inner cavity of the handlebar 23. The front brake cable 11 enters the inner cavity of the handlebar 23 from the cable inlet on the left side of the handlebar 23, then passes through the steerer tube 24, enters the inner cavity of the front fork 22, and finally exits from the front brake cable outlet of the front fork 22, which is integrally formed on the front fork.

[0046] A cable routing gap 28 exists between the outer wall of the vertical tube 24 and the inner wall of the bushing 25. A cable harness positioning hole 29 is provided on the handlebar 23, and the cable routing gap 28 connects to the inner cavity of the handlebar 23 through the cable harness positioning hole 29. The mid-shift cable 13 enters the inner cavity of the handlebar 23 from the left side (viewed from the riding direction) of the handlebar 23, then passes through the cable harness positioning hole 29 and the cable routing gap 28 in sequence to enter the inner cavity of the downtube 26, and finally exits from the mid-shift cable outlet. The rear derailleur cable 14 and the rear brake cable 12 enter the inner cavity of the handlebar 23 from the right side of the handlebar 23, then pass through the cable harness positioning hole 29 and the cable routing gap 28 in sequence to enter the inner cavity of the downtube 26, and finally exit from the rear derailleur cable outlet and the rear brake cable outlet, respectively. The mid-shift cable outlet, rear derailleur cable outlet, and rear brake cable outlet are all integrally formed on the frame body 21. Depending on the needs, when actually threading the wires, it is not necessary for the wires to enter from the lead-in port and exit from the lead-out port. Alternatively, the wires can enter from the lead-out port and exit from the lead-out port.

[0047] There are two ways to set the wiring harness positioning hole 29: The first is to set three wiring harness positioning holes 29 spaced apart from each other, with each hole corresponding to the center derailleur cable 13, rear derailleur cable 14, and rear brake cable 12, respectively. The diameter of each of these three wiring harnesses is compatible with the diameter of its corresponding positioning hole 29, making it less likely for the wiring harnesses to interfere with each other. The second is to set one wiring harness positioning hole 29, which is elongated. The center derailleur cable 13, rear derailleur cable 14, and rear brake cable 12 are threaded side-by-side through the positioning hole 29, ideally without any movement along the length of the hole. This arrangement allows the wiring harnesses to be more concentrated at the bicycle's steering points, minimizing movement when the handlebars 23 turn. This embodiment uses the second method.

[0048] The front brake guide assembly is located in the front fork 22. The front brake guide assembly includes a front brake cable guide plug 32, which is placed in the riser tube 24. The front brake cable guide plug 32 has at least one limiting hole 36 for the cable harness, such as the front brake cable 11, to pass through and for restricting the cable harness, such as the front brake cable 11. The cable harness can be restricted by the fit between the hole and the cable harness, or the front brake cable guide plug 32 can be glued and fixed to the front brake cable 11. The shape of the front brake cable guide plug 32 is adapted to the cross-section of the inner cavity of the riser tube 24, and the front brake cable guide plug 32 can be elastically deformed to be installed in the riser tube 24. The rebound force of the elastic deformation can make the outer edge of the front brake cable guide plug 32 abut against the inner wall (inner cavity wall) of the riser tube 24 to be positioned in the riser tube 24. During assembly, external force can push the cable guide plug to the appropriate position. When the external force disappears, the cable guide plug is positioned in the appropriate position. The elastic force generated by the deformation of the cable guide plug and the friction force of the inner wall of the riser tube 24 can prevent the cable guide plug from sliding. The limiting hole 36 of the front brake cable plug 32 forms a guide channel for the front brake cable 11. After entering the riser tube 24 from the inner cavity of the handlebar 23, the front brake cable 11 directly enters this guide channel (passing through the limiting hole 36 of the front brake cable plug 32) and then exits from the outlet of the front brake cable 11. Of course, a front brake cable plug 32 can also be added to the inner cavity of the front fork 22 to further improve the positional stability of the front brake cable 11. The shape of the front brake cable plug 32 is adapted to the cross-section of the inner cavity of the front fork 22, and the outer edge of the front brake cable plug 32 abuts against the inner wall of the front fork 22. This embodiment uses the front brake cable as an example for explanation, but is not limited to this. The wiring harness can also be a transmission cable or a hydraulic cable. The wiring harness can be a "single wire", or "multiple wires" bundled together, or "multiple different wires" bundled together. The positioning member 33 is described with one limiting hole 36 as an example, with one limiting hole 36 for one wire harness to pass through, but is not limited to this. One limiting hole 36 can also be used for multiple wire harnesses to pass through, or multiple limiting holes 36 can be provided.

[0049] In a preferred embodiment, the front brake guide plug 32 includes an integrally formed positioning member 33 and a support member. The support member is connected to the outer periphery of the positioning member 33. The centerline of the positioning member 32 is arranged along a first direction. If the centerline is the axis of the limiting hole 36 and / or the frustum wall, the limiting hole 36 surrounds the centerline. If the positioning member 33 includes a circumference, the inner hole of the circumference constitutes the aforementioned limiting hole 36. More preferably, the support member includes a deformable section, which includes a plurality of support units 34. The support units 34 are arranged radially around the positioning member 33. The support units 34 are inclined relative to the positioning member 33, so they can also be inclined sections. That is, when the deformable section is in its initial state, it extends from near to far and from inside to outside relative to the positioning member 33 along the first direction. After elastic deformation, it can generate an outward elastic force or an elastic component force. The angle between the support unit 34 and the positioning member 33 is defined as B, and preferably 90° < B ≤ 150°. In this embodiment: the inner and outer walls of the support unit 34 are truncated cones, so that the shape of the support member matches the cross-section of the inner cavity of the fork 22. However, it can also be a truncated pyramidal wall as needed. The deformation section is described using an inclined example, but it is not limited to this. An arc-shaped structure or other structures can also be used as needed. The support unit 34 is fixed to the positioning member 33. However, a truncated cone wall can also be provided between the positioning member 33 and the support unit 34 as needed. The truncated cone wall can be elastically deformable or inelastically deformable. If it is elastically deformable, the entire support member can be elastically deformable. If it is inelastically deformable, only part of the support member can be elastically deformable. One end of the support unit 34 is connected to the edge of the positioning member 33, and the other end of the support unit 34 is suspended. The suspended end of the support unit 34 is provided with a bent part 35. Because the support unit 34 is suspended, it has a strong elastic deformation effect and the support has an initial state and a deformed state. In the deformed state, it can generate elastic force and can be installed in the vertical tube 24. The elastic force is from the inside to the outside or the elastic force component is from the inside to the outside. Through the deformation of several support units 34, the suspended end abuts against the inner wall of the vertical tube 24 to be positioned in the vertical tube 24. This allows the front brake cable plug 32 to better contact the inner wall of the frame, ensuring the stability of the front brake cable plug 32 and the stability of the front brake cable 11, which is conducive to the installation of the front brake cable plug 32. The inclined arrangement of the support unit 34 and the bending portion 35 allow the front brake guide plug 32 to have a certain buffering capacity or elasticity. The shape of the front brake guide plug can be designed to be slightly larger than the inner cross-section of the vertical tube 24. When installed, the front brake guide plug 32 is placed in a slightly compressed (deformed) state within the inner cavity of the vertical tube 24. The rebound force of the elastic deformation makes it difficult for the front brake guide plug 32 to slide, thus positioning the front brake guide plug 32 and ensuring the stability of the front brake line 11. In addition, it also facilitates the assembly of the front brake guide plug 32. This embodiment uses "several support units 34 arranged radially around the positioning member 33" as an example for explanation, but it is not limited to this. It can also be set as a frustum wall as needed. The frustum wall has a groove that extends to the outer perimeter and penetrates both inside and outside. The frustum wall can be a frustum wall with a single cone angle or a frustum wall with multiple frustum walls of different angles connected sequentially.

[0050] Furthermore, to ensure the bending portion 35 functions effectively and facilitates installation, the following design is implemented in this embodiment: the angle between the bending portion 35 and the support unit 34 is defined as A, where A > 180°, and more preferably 185° ≤ A ≤ 225°. This allows for a larger contact area and increased elasticity between the support member and the inner wall of the frame. When the wire plug is made of a material with a high coefficient of friction, the positional stability of the wire plug within the frame can be improved. Additionally, the outer edge of the wire plug can better adapt to the inner cavity of the frame with different cross-sectional shapes, resulting in better versatility. Furthermore, in this embodiment, the ratio of the length L1 of the support unit 34 to the length L2 of the bending portion 35 is preferably (1-3):1, to facilitate the function of the bending portion 35 and promote installation.

[0051] The installation process is as follows: First, pass the front brake cable 11 through the limiting hole 36 of the front brake cable plug 32; then, insert the cable plug 32 into the inner cavity of the vertical tube 24 with the positioning piece 33 in front and the suspended end of the support unit 34 behind, and push it to the appropriate position. The inclined section can play a guiding role to facilitate installation; the elastic deformation and rebound force of the support part abuts against the inner wall of the vertical tube 24 to position the cable plug and the cable harness.

[0052] The rear brake guide assembly is housed in the frame body 21 and includes two first rear brake cable guide plugs 43 and one second rear brake cable guide plug 44. The first rear brake cable guide plugs 43 are located in the downtube 26, with one first rear brake cable guide plug 43 positioned near the bushing 25 and the other near the connection point between the downtube 26 and the rear triangle 27. The shape of the first rear brake cable guide plug 43 is adapted to the cross-section of the downtube 26, and its outer edge abuts against the inner wall of the downtube 26. The second rear brake cable guide plug 44 is located in the left lower fork, its shape adapted to the cross-section of the left lower fork, and its outer edge abuts against the inner wall of the left lower fork. The specific structure and usage of the first and second rear brake cable guide plugs 43 and 44 are similar to those of the front brake cable guide plug 32 and will not be described further.

[0053] The limiting holes of the first rear brake cable plug 43 and the second rear brake cable plug 44 are connected in series to form the guide channel for the rear brake cable 12. The rear brake cable 12 passes through the inner cavity of the handlebar 23, the wiring harness positioning hole 29, and the bushing 25 in sequence before entering the guide channel, and then exits from the outlet of the rear brake cable 12. The intermediate shift guide assembly includes two intermediate shift cable plugs 52, which are placed in the lower tube 26. The first rear brake cable plug 43 can be directly used as the intermediate shift cable plug 52. The specific structure and usage of the intermediate shift cable plug 52 are similar to those of the front brake cable plug 32, and will not be described again. The limiting holes of the two intermediate shift cable plugs 52 are connected in series to form the guide channel for the intermediate shift cable 13. Generally, the outlet of the intermediate shift cable 13 is located at the junction of the lower tube 26 and the rear triangle 27. The intermediate shift cable 13 passes through the inner cavity of the handlebar 23, the wiring harness positioning hole 29, and the bushing 25 in sequence before entering the guide channel, and then exits from the outlet of the intermediate shift cable 13.

[0054] The rear derailleur guide assembly includes two first rear derailleur cable plugs 63 and one second rear derailleur cable plug 64. The first rear derailleur cable plug 63 is placed in the lower tube 26, and the first rear brake cable plug 43 can be directly used as the first rear derailleur cable plug 63. The second rear derailleur cable plug 64 is placed in the right rear lower fork. The specific structure and usage of the first rear derailleur cable plug 63 and the second rear derailleur cable plug 64 are similar to those of the front brake cable plug 32, and will not be described again. The limiting holes of the first rear derailleur cable plug 63 and the second rear derailleur cable plug 64 are connected in series to form the guide channel of the rear derailleur cable 14. The rear derailleur cable 14 passes through the inner cavity of the handlebar 23, the cable harness positioning hole 29, and the bushing 25 in sequence before entering the guide channel, and then exits from the rear derailleur cable 14 outlet.

[0055] The rear brake line 12, intermediate change line 13 and rear change line 14 located in the lower tube 26 share a common wire plug, which can facilitate the installation of the guide structure and reduce the number of accessories.

[0056] Furthermore, in this embodiment, each wire plug (i.e., front brake wire plug 32, first rear brake wire plug 43, second rear brake wire plug 44, intermediate transformer wire plug 52, first rear transformer wire plug 63, and second rear transformer wire plug 64, collectively referred to as the frame internal wiring wire plugs) is provided with only one limiting hole 36. When a wire plug is used for only one wire harness, the diameter of the limiting hole 36 can be adapted to the outer diameter of the wire harness; when a wire plug is used for two wire harnesses, the diameter of the limiting hole 36 can be adapted to the sum of the outer diameters of the two wire harnesses; when a wire plug is used for three wire harnesses, the three wire harnesses are bundled together, and the outer walls of the three wire harnesses can be tangent to the limiting hole 36. Of course, if the wire plug has a certain degree of elasticity, the diameter of the limiting hole 36 can be slightly smaller, just enough to ensure that the wire harness can pass through. Of course, the number of limiting holes 36 on the wire plug can also correspond one-to-one with the wire harness. In this embodiment, each wire plug (i.e., front brake wire plug 32, first rear brake wire plug 43, second rear brake wire plug 44, intermediate changer wire plug 52, first rear changer wire plug 63 and second rear changer wire plug 64 are collectively referred to as the frame internal wiring wire plugs) has a limiting hole for the "rear brake line 12, intermediate changer line 13 and rear changer line 14" to pass through so as to realize the shared wire plug.

[0057] In summary, the wiring harness is supported within the frame cavity by internal cable routing plugs (i.e., front brake cable plug 32, first rear brake cable plug 43, second rear brake cable plug 44, intermediate derailleur cable plug 52, first rear derailleur cable plug 63, and second rear derailleur cable plug 64, collectively referred to as internal cable routing plugs). This ensures the stability of the wiring harness position and prevents it from colliding with the frame's inner wall. The number of internal cable routing plugs can be appropriately increased based on the length of the pipes it passes through to further enhance the wiring harness's positional stability. This invention conceals the wiring harness within the frame, resulting in a neat and uncluttered bicycle exterior. During riding, the wiring harness is less likely to collide with the frame and generate noise. Furthermore, the wiring harness's routing is guided, preventing it from interfering with bicycle steering. This facilitates wiring harness installation while also providing good protection and extending its lifespan, making it highly marketable.

[0058] In some embodiments, a conduit may be added to the guide assembly. The conduit passes through the limiting hole of the wire plug and is limited and engaged with it (by means of gluing, etc.). The wire harness passes through the conduit and can extend to the outlet position of the corresponding wire harness so that the wire harness is well positioned and protected.

[0059] Example 2

[0060] like Figure 8-9 As shown, the difference between this embodiment and Embodiment 1 is that 110°≤A≤170°, and the ratio of the length L1 of the support unit 34 to the length L2 of the bending portion 35 is (1-10):1, more preferably (3-10):1. The wire plug has better elasticity and better cushioning effect. Of course, the wire plugs described in Embodiment 1 and Embodiment 2 can be used interchangeably, that is, the same set of guide components can simultaneously have the wire plugs described in Embodiment 1 and Embodiment 2.

[0061] Example 3

[0062] like Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that the deformable section includes an annular portion 37 that surrounds and is fixed to the positioning member 33. The annular portion 37 can elastically bend and deform along the first direction to form a frustum-shaped wall structure for insertion into the frame. After insertion, the elastic deformation rebound force causes the edge of the annular portion 37 to abut against the inner wall of the frame to position it within the frame, thereby defining the position of the wire plug, the position of the limiting hole, and the position of the wire harness passing through the limiting hole. In this embodiment, the support member has a sheet-like structure when the wire plug is initially in its position, the deformable section has a sheet-like structure, and the deformable section in its deformed state has a frustum-shaped wall structure, that is, it extends from near to far and from inside to outside relative to the positioning member along the first direction. The wire plug in this embodiment is easy to process. The outer circumference of the annular portion can be directly cut, as long as the outer circumference of the annular portion is slightly larger than the mounting tube. The annular portion 37 in this embodiment can be made of elastic steel wire mesh.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
