Description

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] At present, the carbon fiber handlebars on the market are generally connected in a fastening manner. A lower cover is set on the vertical tube, and the handlebar cross tube is clamped between the upper cover and the lower cover by the upper cover. Then, the two sides of the upper cover are fixedly connected with the two sides of the lower cover by bolts, so that the handlebar is clamped on the upper end of the vertical tube, and the lower end of the vertical tube is connected to the front fork. The above setting requires multiple bolts, and the connection of the handlebar is relatively troublesome, and the appearance is not simple. In addition, the fastened bolts are exposed for a long time, easy to rust, and have a short service life. In addition, the above setting, once the bolts on either side of the cover are loose, the handlebar will become loose, and the stability is low. Although the handlebar and the vertical tube can also be formed in one piece, it will be relatively troublesome in production, and the handlebar and the vertical tube are formed in one piece. When either is damaged and needs to be replaced, the cost will be higher. Utility Model Content

[0032] 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.

[0033] Embodiment 1

[0034] like Figures 1 to 7 As shown, this embodiment discloses a handlebar assembly, which includes a handlebar 10, a vertical tube 20 and a clamping assembly 30. The upper end of the vertical tube 20 is plugged into the handlebar 10, and the clamping assembly 30 is used to cooperate with the handlebar 10 to clamp the upper end of the vertical tube 20 inserted into the handlebar 10. 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 vertical tube 20 is usually integrated with the front fork of the bicycle.

[0035] A riser 11 and a mounting groove 12 are provided in the middle area of ​​the handlebar 10. The handlebar 10 is preferably made of carbon fiber material. The handlebar 10 thus provided has a strong structure and is light in weight. In this case, the handlebar 10, the riser 11 and the mounting groove 12 are an integrated structure, which can be integrally formed; when the handlebar 10 is not made of carbon fiber, it can also be fixed as a whole by welding or the like. The handlebar 10, the riser 11 and the mounting groove 12 are designed as an integrated structure, which can be easily assembled and has better structural stability. The mounting groove 12 has only one opening, and the opening is connected to the inner cavity 11 of the riser from the side of the riser 11. The cross section of the lower end of the riser 11 is adapted to the cross section of the upper end of the riser 20, and the upper end of the riser 20 is plugged and matched with the lower end of the riser 11. It is preferred that the cross section of the upper end of the riser 20 is not circular, and the cross section of the upper end of the riser 20 can be a regular polygon, an ellipse, etc. This arrangement can prevent the riser 20 from rotating in the riser 11, which is conducive to the clamping assembly 30 to play its role. In addition, a stopper 13 is provided in the seat tube 11 to limit the position of the seat tube 20, so as to prevent the seat tube 20 from passing through the seat tube 11, and the connection between the installation groove 12 and the seat tube 11 is below the stopper 13. In this example, when viewed from the front direction of the handlebar 10 (i.e., the forward direction of the bicycle), the installation groove 12 is located in front of the seat tube 11. Due to the provision of the installation groove 12, the shape of the corresponding position of the handlebar 10 will be enlarged. Through the above-mentioned provision, the problem of increased wind resistance of the handlebar 10 caused by the provision of the installation groove 12 can be reduced.

[0036] The clamping assembly 30 includes a clamping slider 31, an adjustment block 32 and an adjustment screw 33, wherein the clamping slider 31 and the adjustment block 32 are built into the mounting groove 12. The side wall of the clamping slider 31 can be limitedly matched with the side wall of the mounting groove 12, so that the clamping slider 31 can only move toward the opening direction of the mounting groove 12. Similarly, the side wall of the adjustment block 32 is limitedly matched with the side wall of the mounting groove 12, so that the adjustment block 32 cannot rotate. A first slope 34 is provided on the clamping slider 31, and a second slope 35 matched with the first slope 34 is provided on the adjustment block 32, and one end of the adjustment block 32 away from the second slope 35 abuts against the bottom of the mounting groove 12. The threaded end of the adjusting screw 33 passes through the clamping slider 31 from the outside of the handlebar 10 from bottom to top and is threadedly connected to the adjusting block 32 (with this arrangement, the adjusting screw 33 is not easily visible from the outside of the handlebar 10, and the handlebar 10 is more simple and beautiful). The end cap of the adjusting screw 33 is limitedly matched with the clamping slider 31 or the groove wall of the mounting groove 12 (or the handlebar 10). By rotating the adjusting screw 33, after the end cap of the adjusting screw 33 abuts against the clamping slider 31 or the groove wall of the mounting groove 12, the adjusting screw 33 is continued to be rotated. Because the adjusting block 32 cannot rotate, as the adjusting screw 33 rotates, the adjusting block 32 moves downward, thereby pushing the clamping slider 31 to move toward the opening of the mounting groove 12, and the clamping slider 31 cooperates with the inner tube wall of the vertical tube 11 to clamp the vertical tube 20.

[0037] In order to avoid interference with the adjusting screw 33, an oblong hole 36 is provided on the clamping slider 31 for the threaded end of the adjusting screw 33 to pass through. In addition, a contact surface 37 adapted to the outer wall of the vertical pipe 20 is provided on the clamping slider 31 to increase the contact area and improve the friction. Of course, the contact surface 37 can also be roughened or provided with a rubber pad to further improve the friction.

[0038] The clamping assembly 30 can be installed in the mounting groove 12 when the handlebar 10 is manufactured. In order to prevent the clamping assembly 30 from failing due to deformation of the handlebar 10, a mounting shell 38 that fits the mounting groove 12 can be provided. The clamping slider 31 and the adjustment block 32 are both placed in the mounting shell 38. At this time, the inner cavity of the mounting shell 38 is equivalent to the mounting groove 12. By providing the mounting shell 38, the mounting groove 12 can be fixed when the handlebar 10 is formed, so as to avoid the problem that the clamping assembly 30 cannot move (gets stuck) or moves poorly, and ensure that the vertical pipe 20 can be effectively clamped.

[0039] Embodiment 2

[0040] The difference between this embodiment and the first embodiment is that, when viewed from the front direction of the handlebar 10 (i.e., the forward direction of the bicycle), the mounting groove 12 is located behind the seat tube 11. Figure 8 This arrangement can also reduce the problem of increased wind resistance of the handlebar 10 caused by the installation groove 12.

[0041] The utility model also discloses a bicycle, which adopts the handlebar assembly described in any of the above embodiments. The front part of the bicycle has a simple and beautiful appearance, and the handlebar is conveniently and quickly connected to the front fork.

[0042] 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.
