Description

Technical Field

[0001] This utility model relates to the technical field of bicycles, and in particular to the technical category of an integrated handlebar fixing structure. Background Technology

[0002] The bicycle handlebar stem is typically attached to the top of the bicycle fork at one end and a handlebar tube at the other end. The handlebar stem is the main component for controlling the bicycle's movement and steering, and it has a significant impact on the bicycle's riding comfort and handling stability.

[0003] The most common type of bicycle stem is the clamp type, which clamps it to the seat tube of a toothless fork. In other words, there is a clamping hole on the stem to fit onto the seat tube of the fork, and then fasteners are used to tighten the clamping hole to clamp the top of the seat tube, so as to achieve the purpose of clamping it to the fork.

[0004] However, common bicycle stems have large clamping surfaces and high rigidity due to the large clamping surface of their clamping holes. This requires a large force to tighten the clamping holes to the fork stem, and a secure tightening is not guaranteed. Over-tightening can deform the stem, which is not only unsightly but also affects the operation of the stem. Therefore, improvements are necessary. Utility Model Content

[0005] Therefore, in view of the problems existing in the conventional clamp-on bicycle, the main purpose of this utility model is to provide a bicycle integrated handlebar fixing structure that is easy to clamp and connect; the secondary purpose of this utility model is to provide a bicycle integrated handlebar fixing structure that is conducive to various aesthetic design.

[0006] To achieve the above objectives, this utility model employs the following technical means:

[0007] This utility model provides an integrated handlebar fixing structure for bicycles, comprising a handlebar with a sleeve portion; a vertical tube assembly, which further includes a bundle tube body and several pressing members, wherein the bundle tube body has a deformable portion and at least one non-deformable portion, and the several pressing members are connected to the deformable portion, and the bundle tube body and the several pressing members are inserted into the sleeve portion of the handlebar, and the non-deformable portion of the bundle tube body is connected to an upper opening and a lower opening of the handlebar; and a front fork assembly, wherein a stem tube of the front fork assembly extends sequentially from bottom to top through a frame head tube and the deformable portion of the bundle tube body of the vertical tube assembly, and the stem tube is fixed to the handlebar by the deformation caused by the deformation caused by the compression of the deformable portion by the several pressing members.

[0008] The aforementioned bundle tube body is provided with several transverse grooves to distinguish the bundle tube body into the deformed part, an upper non-deformed part and a lower non-deformed part, wherein the upper non-deformed part and the lower non-deformed part are respectively located above and below the deformed part.

[0009] The aforementioned handle's sleeve portion completely covers the vertical tube assembly, and the upper non-deformable portion and the lower non-deformable portion of the bundle tube body are respectively welded and fixed to the upper opening of the handle and the lower opening opposite to the upper opening.

[0010] The upper perimeter of the deformed portion is larger than the perimeter of the upper non-deformed portion, while the lower perimeter of the deformed portion is smaller than the perimeter of the lower non-deformed portion.

[0011] The aforementioned vertical tube assembly further includes an upper cover that covers the upper opening provided on the handle.

[0012] The aforementioned fork assembly further includes a bearing assembly, a rod, a slat, and a fork section. The bearing assembly is respectively located at the upper and lower ends of the head tube of the frame, the slat is placed inside the seat tube, and the rod extends through the seat tube and is connected to the slat.

[0013] The centers of the upper opening and lower opening of the handle, the bundle of the vertical tube assembly, and the riser of the fork assembly are all maintained on a single center line.

[0014] The deformed portion of the aforementioned bundle tube body is provided with two screw holes and a longitudinal groove, wherein the opening directions of the two screw holes are different, and the longitudinal groove longitudinally cuts through the two screw holes and the bundle tube body.

[0015] The handle described above has a through hole for each of the several pressure members provided on the vertical tube assembly.

[0016] 1. The present invention mainly divides the stem tube of the vertical tube assembly installed in the sleeve portion of the handle into a deformable part and at least one non-deformable part. The non-deformable part is used to connect to the handle, while the deformable part is connected to the stem tube of the fork assembly by the compression deformation of several pressing members. When the deformable part is compressed, the other parts will not be affected by deformation. That is, the handle and the stem tube can be connected together without applying too much force, and can rotate together on the same center line. Therefore, the present invention has better steering and control performance.

[0017] 2. The handle of this utility model is connected to the seat tube of the fork assembly by means of the deformation part of the bundle tube body using the compression deformation of the compression member. The upper non-deformable part and the lower non-deformable part of the bundle tube body are respectively welded and fixed to the upper opening and the lower opening of the handle, so that the handle and the bundle tube body are integrated. This allows the deformation part of the bundle tube body and several compression members to be hidden in the sleeve part of the handle, which makes the handle more suitable for shape change design and achieves an aesthetic effect.

Detailed Implementation

[0025] This utility model relates to an integrated handlebar fixing structure for bicycles. It primarily provides an innovative structure for integrating bicycle handlebars with the front fork assembly, allowing the handlebars to be connected to the front fork without applying excessive force. This improves the operability of the handlebars in controlling the bicycle's steering mechanism, such as the front fork. Figure 1 As shown, the integrated handlebar fixing structure A of the bicycle includes: a handlebar 1, a vertical tube assembly 2, and a front fork assembly 3; the above components are described below with reference to the accompanying drawings.

[0026] like Figure 2 and Figure 3 As shown, the handle 1 has a sleeve portion 11 and an upper opening 12 and a lower opening 12a located above and below the sleeve portion 11, respectively. The upper opening 12 of the handle 1 is connected to the lower opening 12a. The handle 1 also has several through holes 13 that are horizontally penetrating the inner wall of the sleeve portion 11.

[0027] like Figures 4 to 6 As shown, the aforementioned vertical tube assembly 2 further includes a bundle of tubes 21, several pressing members 22, and a top cover 23. The bundle of tubes 21 is provided with a deformable portion 211 and at least one or more non-deformable portions. Preferably, the non-deformable portions are an upper non-deformable portion 214 and a lower non-deformable portion 215, located above and below the deformable portion 211, respectively. That is, the bundle of tubes 21 has two horizontal transverse grooves 210 on its upper and lower sides. These two transverse grooves 210 can distinguish the bundle of tubes 21 from the deformable portion 211 and the upper non-deformable portion 214 and the lower non-deformable portion 215, which are respectively connected above and below the deformable portion 211. The upper periphery of the deformable portion 211 is larger than the periphery of the upper non-deformable portion 214, and the deformable portion 214... The lower periphery of 11 is smaller than the periphery of the lower non-deformable part 215; and the several pressing members 22 are horizontally connected to the deformable part 211. That is, the deformable part 211 of the bundle tube body 21 has two screw holes 212 and a longitudinal groove 213. The opening directions of the two screw holes 212 are different to provide for the connection of two pressing members 22. The longitudinal groove 213 is longitudinally cut through the two screw holes 212 and the bundle tube body 21 in the up and down direction. The bundle tube body 21 and the several pressing members 22 are all placed into the sleeve part 11 of the handle 1. The top surface and bottom surface of the bundle tube body 21 are welded to the upper opening 12 and the lower opening 12a of the handle 1, respectively. The upper cover 23 is provided to be fitted into the upper opening 12 of the handle 1.

[0028] Please see Figure 3 and Figure 5As shown, the aforementioned front fork assembly 3 further includes a seat tube 31, a bearing assembly 32, a rod 33, a sprocket 34, and a fork section 35. The bearing assembly 32 is respectively located at the upper and lower ends of the bicycle frame head tube 4, allowing the seat tube 31 of the front fork assembly 3 to be pivotally connected to the bicycle frame head tube 4, thus enabling the front fork assembly 3 to perform steering operations. The sprocket 34 is placed inside the seat tube 31, and the rod 33 extends into the seat tube 31. 1 is connected to the leaflet 34, that is, by adjusting the rod 33, the leaflet 34 is expanded and adjusted to adjust the relative position and height of the handle 1 on the riser 31; when the riser 31 is inserted into the deformable part 211 of the bundle tube 21, the deformable part 211 is compressed and deformed by the several pressing members 22, so that the riser 31 can be fastened and positioned at multiple points, so that the fork assembly 3 can be turned by the linkage control of the handle 1.

[0029] Therefore, as Figure 2 , Figure 5 and Figure 6 As shown, this utility model provides a preferred solution for an integrated bicycle handlebar fixing structure. The integrated bicycle handlebar fixing structure A primarily involves pre-installing and welding the vertical tube assembly 2 into the inside of the sleeve portion 11 of the handlebar 1. Then, the deformable portion 211 of the bundle tube body 21 is fitted onto the exposed portion of the riser tube 31 of the fork assembly 3, which has already passed through the head tube 4 of the frame. Typically, this exposed portion is at the top of the riser tube 31. Finally, several pressing members 22 are horizontally locked in from the two screw holes 212, respectively, to achieve the desired effect. The two transverse grooves 210 and the longitudinal groove 213 are pressed to cause physical deformation of the deformable part 211, thereby enabling the bundle tube body 21 to clamp the upper part of the riser tube 31 and move it. That is, the handle 1 is provided with the through hole 13 for each of the several pressing members 22 provided for the riser tube assembly 2, so that the tool can be inserted into the through hole 13 to operate the several pressing members 22 to lock into the two screw holes 212 on the left and right respectively and to tighten the deformable part 211 to clamp the upper part of the riser tube 31, so that the handle 1 can move the front fork assembly 3 to control the bicycle's movement and steering.

[0030] Furthermore, the vertical tube assembly 2 is inserted into the socket portion 11 of the handle 1, and the upper non-deformable portion 214 and the lower non-deformable portion 215 located above and below the bundle tube body 21 are respectively aligned with the upper opening 12 and the lower opening 12a of the socket portion 11 of the handle 1 and welded to fix it, so that the deformable portion 211 of the bundle tube body 21 is covered inside the socket portion 11 of the handle 1, and the connection marks of the vertical tube assembly 2 are not visible from the outside. Then, the upper cover 23 is placed over the upper opening 12a. 2. This achieves the purpose of beautifying and changing the style of the handlebar 1; in addition, the upper opening 12 of the handlebar 1, the bundle tube body 21 of the vertical tube assembly 2, and the seat tube 31 of the fork assembly 3 are all kept at the center line c, so that the handlebar 1 and the seat tube 31 are not affected by the physical deformation of the deformable part 211, and the handlebar 1 can maintain the rotation of the center line c when it rotates, so that the handlebar 1 and the fork assembly 3 can rotate smoothly and without hindrance, thereby improving the feel of the handlebar 1 when operating the bicycle steering.

[0031] It should be noted that the above description is the technical principle used in the specific embodiments of this utility model. If any changes are made in accordance with the concept of this utility model, and the resulting functions and effects do not exceed the spirit covered by the specification and drawings of this utility model, they should be included within the protection scope of this utility model.
