Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a handlebar assembly and a bicycle using the handlebar assembly. Background Art

[0002] Most of the carbon fiber handlebars on the market are connected in a fastening manner. For example, a bolt-locked clamp is set in the middle area of ​​the handlebar, and the front fork is connected to the clamp through a vertical tube. The upper end of the vertical tube is inserted into the clamp, and the screws are locked. The vertical tube is rotated and connected to the shaft sleeve at the front end of the frame, thereby realizing the connection between the handlebar, frame and front fork. However, after a long period of use, the bolts of the clamp are easy to loosen, which leads to the problem of crooked handlebars. Although the handlebars and the front fork can be welded and fixed, there are more and more bicycles purchased online, and many consumers assemble them online by themselves. If the handlebars are welded to the front fork, it is not conducive to transportation. In addition, the clamp is used to connect the handlebar and the vertical tube, and the clamp, screws and other parts are exposed to the outside, which are easy to rust or damage, and the appearance of the handlebar position is not simple.

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] like Figures 1 to 10 As shown, the utility model discloses a handlebar assembly, which includes a handlebar 10, a vertical tube 20 and a connecting assembly 30. The upper end of the vertical tube 20 is plugged with the handlebar 10, and the connecting assembly 30 is used to lock the handlebar 10 and the vertical tube 20. The lower end of the vertical tube 20 can be directly integrated with the front fork, or can be connected by bolts or the like. The middle section of the vertical tube 20 is rotatably connected to the shaft sleeve 51 at the front end of the frame. In this case, the handlebar 10 and the frame are both hollow structures, and the cavity of the frame is connected to the shaft sleeve 51. The brake line and the speed change line 43 extend into the cavity of the handlebar 10 and then enter the tube cavity of the vertical tube 20. The front brake line 41 directly extends into the tube cavity of the front fork and is led out near the installation position of the front brake. The rear brake line 42 and the speed change line 43 enter the shaft sleeve 51 and the cavity of the frame from the side wall opening of the middle section of the vertical tube 20, and are led out near the installation position of the rear brake and the transmission, respectively.

[0038] Specifically, first wiring holes 11 are provided on both sides of the handlebar 10, and second wiring holes 12 and a riser 13 are provided in the middle area of ​​the handlebar 10, and the handlebar 10 and the riser 13 are integrally formed. The first wiring hole 11 is connected to the second wiring hole 12, and the second wiring hole 12 is located on one side of the riser 13, and the second wiring hole 12 is connected to the riser 13. The brake cable and the shift cable 43 enter the cavity of the handlebar 10 from the first wiring hole 11, and then exit from the second wiring hole 12 and enter the riser 13.

[0039] A blocking cover 14 is detachably connected to the upper tube opening of the riser 13 for blocking and shielding the riser 13. In this case, the blocking cover 14 is embedded in the riser 13. A mounting groove matched with the blocking cover 14 can be formed at the upper tube opening of the riser 13, or a base 15 is provided in the upper tube opening of the riser 13, and a mounting groove matched with the blocking cover 14 is formed by the base 15 cooperating with the riser 13. In this case, the latter is preferred to facilitate the processing and manufacturing of the handlebar 10.

[0040] The cross section of the upper end of the vertical tube 20 is a polygonal structure, preferably a regular polygonal structure, and in this case, it is a regular hexagon. The cross section of the lower end of the vertical tube 13 is adapted to the cross section of the upper end of the vertical tube 20, and the upper end of the vertical tube 20 is plugged and matched with the lower end of the vertical tube 13. This arrangement can ensure that the positional relationship between the handlebar 10 and the vertical tube 20 remains constant, and the handlebar 10 has strong stability and reliable connection. In addition, a limit stop ring 16 is provided in the vertical tube 13 to prevent the vertical tube 20 from extending out of the vertical tube 13, and the setting of the limit stop ring 16 shall not interfere with the use of the connecting assembly 30. A third wiring hole 21 is provided on the side wall of the vertical tube 20, and the third wiring hole 21 is connected to the tube cavity of the vertical tube 20. The rear brake cable 42 and the gearshift cable 43 enter the cavity of the frame from the third wiring hole 21.

[0041] The connection assembly 30 is placed in the vertical pipe 13, and includes a locking screw 31, an expansion piece 32, a first expansion piece 33, and a second expansion piece 34. A fourth wiring hole 35 is provided on the locking screw 31, and the fourth wiring hole 35 penetrates the locking screw 31 along the central axis direction of the locking screw 31. The first expansion piece 33, the expansion piece 32, and the second expansion piece 34 are sequentially sleeved on the locking screw 31, and the first expansion piece 33 is limitedly matched with the end cap of the locking screw 31, and the first expansion piece 33 is also limitedly matched with the limit ring 16. The second expansion piece 34 is threadedly connected to the locking screw 31, and the expansion piece 32 and the second expansion piece 34 extend into the vertical pipe 20. By rotating the locking screw 31, the first expansion member 33 and the second expansion member 34 are both expanded and matched with the expansion member 32. When the first expansion member 33 and the second expansion member 34 are expanded and matched with the expansion member 32, the expansion member 32 can be driven to expand and match with the tube cavity of the vertical tube 20, thereby achieving the fastening of the handlebar 10 and the vertical tube 20. After such a setting, the handlebar 10 and the vertical tube 20 are reliably connected and not easy to loosen, and the connecting assembly 30 can be completely hidden, which is conducive to improving the aesthetics of the position of the handlebar 10.

[0042] In order to facilitate the cooperation and use of the expansion member 32 with the first tension member 33 and the second tension member 34, a first tensioning inclined surface 36 is provided at both ends of the expansion member 32, and a second tensioning inclined surface 37 that cooperates with the first tensioning inclined surface 36 is provided on the first tension member 33 and the second tension member 34. In addition, in order to facilitate the installation of the expansion member 32 and ensure that it can be effectively expanded, in this case, the expansion member 32 includes at least two arc plates 38 and at least one elastic ring 39, the arc plates 38 surround a tubular structure, the elastic ring 39 is hooped on the outside of the tubular structure, and a limiting groove for limiting the elastic ring 39 is provided on the outer wall of the arc plate 38 to prevent the elastic ring 39 from falling off during installation. Under the action of the elastic ring 39, the expansion piece 32 can be well retained on the locking screw 31, and the setting of the elastic ring 39 can increase the friction between the expansion piece 32 and the inner wall of the vertical pipe 20 and increase the friction between the expansion piece 32 and the second expansion piece 34, so that when the locking screw 31 is rotated, the second expansion piece 34 can be rotated relative to the locking screw 31, thereby making the first expansion piece 33 and the second expansion piece 34 approach each other to complete the locking operation.

[0043] After the connection assembly 30 is installed, wiring can be performed. The brake cable and the shift cable 43 enter the inner cavity of the handlebar 10 from the first wiring hole 11, and then are led out from the second wiring hole 12 to the upper end of the seat tube 13, and then enter the tube cavity of the vertical tube 20 through the fourth wiring hole 35. The front brake cable 41 is directly led out from the lower end of the tube cavity of the vertical tube 20 to the front fork, and the rear brake cable 42 and the shift cable 43 are led from the third wiring hole 21 to the cavity of the frame, so as to achieve the purpose of hiding the brake cable and the shift cable 43.

[0044] In order to make the handlebar 10 better match with the shaft sleeve 51 at the front end of the frame, a stopper 17 for limiting the match with the shaft sleeve 51 of the frame is provided on the outer edge of the lower tube opening of the seat tube 13. At this time, the upper end of the front fork is also limited to match with the shaft sleeve 51, so as to ensure the stable installation of the handlebar 10. Because the cross section of the vertical tube 20 is a polygonal structure, in order to ensure that the vertical tube 20 rotates smoothly on the shaft sleeve 51, a gasket 22 for rotating with the shaft sleeve 51 of the frame is also sleeved on the vertical tube 20. The inner circle of the gasket 22 is tangent to the vertical tube 20 or the shape is adapted (i.e., it is a positive polygon deformation), and the outer circle of the gasket 22 is provided with a conical surface 23, which can be partially inserted into the shaft sleeve 51. Through the provision of the gasket 22, a certain gap can be provided between the inner cavity wall of the shaft sleeve 51 and the outer wall of the vertical tube 20, which is more conducive to the routing of the rear brake cable 42 and the shift cable 43.

[0045] The utility model also discloses a bicycle, which includes a frame (not shown in the figure), a front brake line 41, a rear brake line 42, a front fork (not shown in the figure) and the above-mentioned handlebar assembly, wherein a shaft sleeve 51 is provided at the front end of the frame, a vertical tube 20 is rotatably connected in the shaft sleeve 51, and the lower end of the vertical tube 20 is connected to the front fork, and the frame and the front fork are both hollow structures. One end of the front brake line 41 is exposed to the handlebar, and the other end of the front brake line 41 is led out to the outside of the front fork after passing through the first wiring hole 11, the second wiring hole 12, the vertical tube 13, the fourth wiring hole 35, the tube cavity of the vertical tube 20 and the inner cavity of the front fork in sequence. One end of the rear brake line 42 is exposed to the handlebar 10, and the other end of the rear brake line 42 is led out to the outside of the frame after passing through the first wiring hole 11, the second wiring hole 12, the vertical tube 13, the fourth wiring hole 35, the tube cavity of the vertical tube 20, the third wiring hole 21, the shaft sleeve 51 and the inner cavity of the frame in sequence. Of course, if the bicycle also has a speed change cable 43, its routing method is the same as the rear brake cable 42, except for the different lead-out position of the frame.

[0046] When the bicycle is assembled, when the handlebar 10 is aligned with the frame, the third wiring hole 21 is directly opposite to the connection between the frame cavity and the shaft sleeve 51. The connection between the frame cavity and the shaft sleeve 51 can be adaptively enlarged to avoid friction with the rear brake cable 42 and the gear shift cable 43. In addition, the gap between the outer wall of the vertical tube 20 and the inner wall of the shaft sleeve 51 can also reduce the friction of the rear brake cable 42 and the gear shift cable 43.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
