Description

Bicycle wiring kit

The present invention relates to bicycles, and in particular to a wiring assembly for a bicycle.

Generally, bicycles use multiple wires to control the movements of various mechanisms, such as the gearshift system, brake system, etc. The wires can be cables for physical operations, wires for transmitting electronic signals, or pipes for hydraulic transmission. Most existing bicycles will guide the wires through the handlebars into the handlebar stem and the head tube, or directly from the handlebar stem or the head headset into the head tube to avoid the wires being exposed and easily damaged.

However, the wiring method of introducing the wires through the handlebars is not convenient during assembly and is not conducive to maintenance and replacement; the wiring method of introducing the wires directly from the handlebar stem or the front headset requires opening a threading hole, which makes it easy for liquid to flow into the handlebar stem or the front headset through the threading hole, thereby causing concerns such as rusting, damage, and inability to operate smoothly of the parts, which has shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and advanced bicycle wiring assembly to solve the above problems.

The main purpose of the present invention is to provide a wiring assembly for a bicycle that is easy to lay and has good waterproof effect.

To achieve the above-mentioned purpose, the present invention provides a bicycle wiring assembly, which is provided between a handlebar stem and a head tube of a bicycle, and a channel for passing at least one wire is provided between the head tube and a front fork vertical tube of the bicycle. The bicycle wiring assembly includes: a cover. The cover includes a sleeve portion for sleeved on the front fork vertical tube and a shielding portion extending radially outward from the sleeve portion, and the shielding portion surrounds an opening that opens toward a side away from the handlebar stem.

The "one" or "at least one" before the terms mentioned in the text does not limit the quantity. It can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained first.

Please refer to Figures 1 to 7, which show a preferred embodiment of the present invention. The bicycle wiring assembly 1 of the present invention is provided between a handlebar stem 2 and a head tube 3 of a bicycle. There is a channel 6 for passing at least one wire 5 between the head tube 3 and a front fork stem 4 of the bicycle. The bicycle wiring assembly 1 includes: a cover 10.

The cover 10 includes a sleeve portion 11 for sleeved on the front fork vertical tube 4 and a shielding portion 12 extending radially outward from the sleeve portion 11. The shielding portion 12 extends along a length direction of the handlebar stem 2 and surrounds an opening 121 that is open to a side away from the handlebar stem 2. Thus, the at least one wire 5 can be introduced into the head tube 3 through the opening 121, which is convenient for wiring. The opening 121 is open downward to effectively prevent water from rusting and damaging the internal parts.

The wiring assembly 1 of the bicycle further comprises a ring seat 20 for being sleeved on the front fork vertical tube 4, the ring seat 20 comprises at least one first wire groove 21 for passing the at least one wire 5, the at least one first wire groove 21 is connected to the opening 121 and the channel 6. In an axial direction A of the sleeve portion 11, the shielding portion 12 completely shields the at least one first wire groove 21, and the shielding portion 12 protrudes radially from the at least one first wire groove 21 by a distance D1 that is not less than twice a radial dimension D2 of the first wire groove 21, and has a good waterproof effect. Preferably, the shielding portion 12 includes two outer side surfaces 122 located on opposite sides of the opening 121, and the two outer side surfaces 122 extend obliquely toward one side away from the handlebar stand 2, as shown in FIG. 6, so as to guide the liquid and prevent the liquid from entering the opening 121.

Specifically, the shielding portion 12 includes a baffle 123 and two side plates 124 provided on two opposite sides of the baffle 123. The height of each side plate 124 protruding from the baffle 123 is not less than 5 mm, and the shielding effect is good. A surface 125 of the baffle 123 facing the handle riser 2 extends from the two side plates 124 in an inward concave arc to fit the handle riser 2, and the assembly stability and aesthetics are good. Preferably, the surface 125 of the baffle 123 facing the handle riser 2 is provided with two grooves 126, and the two grooves 126 extend corresponding to the two side plates 124, respectively, so that the shielding portion 12 has appropriate flexibility and can fit the handle riser 2.

In this embodiment, the sleeve portion 11 includes an inner wall 111 and an outer wall 112 that surrounds the inner wall 111. The shielding portion 12 is formed by the outer wall 112, which has good structural strength and waterproof effect. The sleeve portion 11 also includes a plurality of reinforcing ribs 113 connected between the inner wall 111 and the outer wall 112, which can effectively improve the structural strength and help to reduce weight. A positioning protrusion 114 is provided on one side of the sleeve portion 11 that is relatively far away from the ring seat 20. The positioning protrusion 114 is embedded in the handle stand pipe 2, and the assembly stability is good.

Preferably, the cover 10 further includes a first rib 13 protruding from the baffle 123 and a second rib 14 transverse to the first rib 13. The first rib 13 is located in the opening 121 and connected between the two side plates 124. The second rib 14 is connected between the first rib 13 and the inner wall 111, so as to achieve a reinforcement effect and prevent the shielding portion 12 from bending, deforming, or breaking relative to the sleeve portion 11.

The wiring assembly 1 of the bicycle further includes at least one spacer 30, 30a sandwiched between the cover 10 and the ring seat 20. Each of the spacers 30, 30a is sleeved on the front fork vertical tube 4 and includes at least one second wire groove 31 connected to the opening 121 and the at least one first wire groove 21. The distance between the cover 10 and the ring seat 20 can be adjusted according to the distance between the handlebar vertical tube 2 and the head tube 3. The application range is wide and the assembly stability is good. For example, the wiring assembly 1 of the bicycle may include two spacers 30, 30a, whose thicknesses are 5 mm and 10 mm respectively. The user may choose to use the two spacers 30, 30a at the same time, use only one of the spacers 30, 30a, or not use the two spacers 30, 30a according to the structural requirements of the existing bicycle.

In this embodiment, each of the spacers 30, 30a further includes a first end 32 and a second end 33. The first end 32 is provided with a buckle protrusion 321, and the second end 33 is provided with a buckle groove 331. The buckle protrusion 321 and the buckle groove 331 are buckled to form a sleeve 34 for sleeve connection to the front fork vertical tube 4. As shown in FIG. 5, the sleeve 34 is connected to the at least one second wire groove 31, and the structure is simple and easy to disassemble. However, each of the spacers can also be a non-detachable closed ring, and when the handlebar riser is detached, it can also be directly sleeved on the front fork vertical tube.

With reference to FIG. 7, when in use, the at least one wire 5 can pass through the opening 121, the at least one first wire groove 21 and the at least one second wire groove 31 into the channel 6, which is convenient for wiring and the shielding portion 12 can effectively shield the at least one first wire groove 21 and/or the at least one second wire groove 31, and the waterproof effect is good.

The cover 10 and the at least one spacer 30, 30a are respectively provided with a first alignment portion 15, 35 on one side facing the ring seat 20, and the ring seat 20 and the at least one spacer 30, 30a are respectively provided with a second alignment portion 22, 36 on one side facing the cover 10. The first alignment portion 15, 35 and the second alignment portion 22, 36 can be detachably engaged with each other. Each of the first alignment portions 15, 35, for example, includes at least one protrusion, and each of the second alignment portions 22, 36, for example, includes at least one notch, so as to avoid relative displacement and achieve an alignment effect for stable assembly.
