Detailed Description

The following three embodiments are described below with reference to the drawings.

Referring to fig. 1, fig. 2 and fig. 4, the handlebar stem 10 is disposed on a front tube 3 of a frame 2, a head cup 4 is sleeved on the front tube 3, a bearing 5 is disposed inside the head cup 4, and the bearing 5 and the front tube 3 are coaxially disposed. The front tube 3 is used for mounting a front fork 6, the front fork 6 has a front fork stem 7, and the front fork stem 7 passes through the front tube 3 and the head bowl 4 and protrudes above the head bowl 4.

Please refer to fig. 2 and fig. 3. The handlebar stem 10 includes a handlebar stem 20, a body 30 and a front fork stem 40, the handlebar stem 20 is transversely extended and has a front axle hole 21, a handlebar (not shown) is sleeved on the front axle hole 21, and the handlebar stem 20 is provided with a screw S1 for tightening the handlebar. The front fork strap 40 extends longitudinally and has a rear axle hole 41, the rear axle hole 41 is used for sleeving the front fork stem 7, and the front end of the bottom of the front fork strap 40 has a through hole 42. The front fork strap 40 is also provided with screws S2 to tighten the front fork stem 7. The body 30 is hollow, and the front and rear ends thereof are connected to the handle ring 20 and the front fork ring 40, respectively. The body 30 also has a through hole 31, and the through hole 31 communicates the inside of the body with the rear axle hole 41.

Please refer to fig. 2 to fig. 4. The handlebar stem 10 further has a sleeve member 50, and the front fork stem 7 is tightened by the front fork ring 40 through the sleeve member 50 (the sleeve member 50 is disposed between the front fork ring 40 and the front fork stem 7). The sleeve member 50 is formed in a hollow circular tube shape and has an opening (see the place of the member 51) serving as a wiring channel 51 (hereinafter, referred to as the wiring channel 51), and the wiring channel 51 extends to the top surface 53 and the bottom surface 54 of the sleeve member 50, so that the cross section of the sleeve member 50 is substantially in a C-shape. The sleeve member 50 has a length in the axial direction such that when the front fork stem 7 is tightened by the front fork ring 40 through the sleeve member 50, the sleeve member 50 can abut against the inner ring surface of the bearing 5, and the wiring channel 51 can pass through the interior of the head bowl 4 and the bearing 5 and extend downward to the interior of the front pipe 3. In order to allow the sleeve member 50 to have a slight inward elastic deformation margin, so that the front fork stem 7 can be tightened by the front fork strap 40 through the sleeve member 50, in the present embodiment, the sleeve member 50 is further provided with a plurality of slots 52, each slot 52 penetrates through the inner and outer annular surfaces 55, 56 of the sleeve member 50, and the slots 52 extend up and down to the top surface 53 or the bottom surface 54 of the sleeve member 50.

The wiring channel 51 is used for routing the cable C, so that the wiring channel 51 is directly connected to the through hole 42 in the direction of the wiring channel 51, so that the cable C can be routed from the handlebar to the interior of the front tube 3 through the bottom side of the handlebar stem 10, the through hole 42 and the wiring channel 51 in sequence. In the present embodiment, the wiring channel 51 extends through the inner and outer annular surfaces 55, 56 of the sleeve member 50, and although it is helpful for the sleeve member 50 to elastically deform to urge the front fork riser 7, it is contemplated that the wiring channel 51 may be configured otherwise, such as by not extending through the inner and outer annular surfaces 55, 56, so long as the cable C can be routed within the wiring channel 51.

Optionally, the handlebar stem 10 further has a bottom cover 60, and the bottom cover 60 has a screw hole 61, so that the user can use a screw to lock the bottom cover 60 to the bottom side of the body 30 and shield the through hole 42, thereby shielding the cable C.

Please refer to fig. 4. Through the structure of the handlebar stem 10, a user can conveniently and easily route the cable C to the interior of the front tube 3 through the bottom side of the handlebar stem 10, the through hole 42 and the wiring channel 51 in sequence, so that most of the cable C is not exposed out of the frame 2, thereby not only avoiding the problem of messy lines, but also optimizing the overall appearance of the whole bicycle.

The present invention also provides a second embodiment, please refer to fig. 5. The structure of the handlebar stem 10 of the second embodiment is substantially the same as that of the first embodiment, one of the differences is that the cable C is routed from the inside of the body 30 to the inside of the head tube 3 through the through hole 31 and the wiring channel 51, so that most of the cable C is not exposed, the problem of messy wiring can be avoided, and the overall appearance of the entire bicycle can be optimized.

It should be noted that, since the cable C is routed through the inside of the body 30, the wiring channel 51 does not necessarily extend to the top surface 53 of the sleeve member 50.

the present invention further provides a third embodiment, please refer to fig. 6. The structure of the handlebar stem 10 of the third embodiment is substantially the same as that of the first embodiment, one difference being that the cable C is not routed to the wiring channel 51 through the through holes 31, 42 (i.e., the through holes 31, 42 can be omitted), but instead is routed directly from the top side of the body 30 to the interior of the head tube 3 through the wiring channel 51 passing through the top surface 53 and the bottom surface 54, which also avoids the problem of wiring clutter and optimizes the overall appearance of the entire bicycle.

The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
