Description

Technical Field

[0001] This utility model relates to the field of bicycle component technology, and in particular to a bicycle handlebar assembly. The handlebar assembly has an assembly structure that allows the handlebar to be directly assembled to the stem body using simple connecting elements, thereby reducing structural costs and providing the advantage of convenient installation. Background Technology

[0002] The stem of a bicycle, commonly known as the handlebar, serves as the connecting element between the handlebars and the fork stem. One end of the stem is fitted with the horizontal handlebar, while the other end is fitted with the vertical fork stem. The stem can also be provided with different angle specifications, allowing the handlebar to be fixed at a position higher or lower than the horizontal position of the stem to suit different riding postures.

[0003] In the past, when assembling handlebars and stems, an end cap was typically used to secure the handlebars to one end of the stem, with the handlebars fitting between the stem and the end cap. Patent publication M294472 discloses a bicycle handlebar stem with improved fit. It places the handlebars in the arc-shaped groove of a C-shaped clamp on the stem, then closes the end cap and secures it to the C-shaped clamp with bolts. The end cap then presses against the C-shaped clamp, holding the handlebars between the end cap and the C-shaped clamp. However, during handlebar installation, simply placing the handlebars in the arc-shaped groove of the C-shaped clamp causes them to detach. Therefore, the installer needs to hold both the handlebars and the end cap with one hand while simultaneously tightening the bolts with the other, making installation inconvenient.

[0004] Furthermore, with prolonged use, the screws securing the end caps and C-clamps inevitably loosen, weakening the clamping force. If the rider applies excessive force to the handlebars, the handlebars may rotate, potentially causing a dangerous situation while riding. Patent Publication No. I681896 provides a bicycle handlebar and stem assembly structure that forms a coupling seat on the handlebars, allowing the stem to be secured to the handlebars with screws, eliminating the need for an end cap structure. While this design prevents the handlebars from rotating during riding, it is structurally much more complex. The handlebar coupling seat must be shaped to correspond to the shape of the stem, increasing manufacturing costs.

[0005] Therefore, the applicant considered how to provide a structure that allows operators to easily assemble the handlebars and vertical tubes while also having a simple structure. Utility Model Content

[0006] In view of the many defects of the existing bicycle handlebar assembly, the main purpose of this utility model is to provide a bicycle handlebar assembly that is easy to assemble, wherein the handlebar and the stem body form an assembly structure, and the stem body can stably support the handlebar during the installation process, making it convenient for operators to install.

[0007] To achieve the aforementioned main objectives, this utility model provides a bicycle handlebar assembly, comprising a handlebar, a stem body, and a connecting assembly. The handlebar has a first fixing portion located at its center. The stem body has a second fixing portion and a sleeve portion, respectively located at its two ends. The second fixing portion forms an arc-shaped connecting groove, and the handlebar is positioned within this groove, such that the groove covers a portion of the first fixing portion of the handlebar, with the opposite ends of the groove forming an axis that extends beyond the center point of the first fixing portion. The connecting assembly has a washer body and a connecting structure for connecting washer bodies. The washer body abuts against the portion of the first fixing portion of the handlebar not covered by the connecting groove of the stem body. The connecting structure passes through the first fixing portion of the handlebar and is connected to the second fixing portion of the stem body.

[0008] Through the aforementioned technical features, the connecting structure passes through the handlebars and fixes them to the stem body, preventing the handlebars from easily wobbling during riding and achieving a good fixing effect. When installing the handlebars to the stem body, the handlebars can first be placed in the connecting groove of the stem body. Since the circumference of the connecting groove surface exceeds half the circumference of the first fixing part, the connecting groove can provide a slight fixing capacity to support the handlebars, preventing them from easily falling off. This allows the installer to simply hold the connecting component while installing it, making it a structure that is easy to install.

[0009] Preferably, the first fixing part of the handlebar has multiple through holes. Therefore, by providing through holes only in the first fixing part of the handlebar, and without forming a complex assembly structure, it can be fixed to the riser body by connecting components, which can effectively save manufacturing costs.

[0010] Preferably, the second fixing part of the riser body forms a plurality of locking grooves, which are formed by the recessed surface of the connecting groove, so that the connecting structure of the connecting component locks into the locking grooves. Therefore, by locking the connecting structure into the locking grooves, a good fixing effect can be provided between the handlebar and the riser body, so that the handlebar will not wobble due to external force.

[0011] Preferably, the second fixing part of the vertical tube body and the sleeve part have an included angle greater than 90 degrees and less than 100 degrees. Therefore, the second fixing part is inclined upwards, so that the connecting groove can more stably hold the handlebar in position when receiving it, improving the convenience of assembly for the operator. If the included angle is less than 90 degrees, the handlebar will easily fall off the connecting groove; if the included angle is greater than 100 degrees, the installation angle of the handlebar is too high, which is not conducive to the rider's grip on the handlebar.

[0012] Preferably, the connecting groove of the vertical tube body is divided into an upper arc segment and a lower arc segment from the central axis of the second fixing part, and the circumference of the upper arc segment is smaller than that of the lower arc segment. Therefore, the lower arc segment can better support the handlebar, and the handlebar is difficult to fall off from the connecting groove even if the operator does not hold the handlebar with their hands.

[0013] Preferably, the gasket body of the connecting assembly forms multiple locking holes that penetrate the gasket body, and the connecting structure includes multiple locking elements that pass through the locking holes of the gasket body and the first fixing part of the handlebar and lock to the second fixing part of the riser body. Therefore, the gasket body only has multiple locking holes, which are used in conjunction with locking elements. The locking elements pass through the gasket body and the handlebar in sequence and are then fixed to the riser body, allowing the handlebar to be installed to the riser body with a simple structure.

[0014] Preferably, the gasket body of the connecting component extends to form an accessory bracket. Therefore, an instrument can be mounted on the accessory bracket, allowing the rider to view current riding information via the instrument.

[0015] The detailed structure, features, assembly, and usage of the bicycle handlebar assembly provided by this utility model will be described in the subsequent detailed description of the embodiments. However, those skilled in the art will understand that these detailed descriptions and the specific embodiments listed for implementing this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0045] Please see Figures 1 to 4 The bicycle handlebar assembly 10 provided by this utility model mainly includes a handlebar 20, a vertical tube body 30, and a connecting component 40.

[0046] The handlebar 20 has a hollow structure and its form is not limited to flat handlebars or curved handlebars. There is a first fixing part 21 in the center of the handlebar 20, forming two through holes 211. The two through holes 211 are spaced apart and pass through the first fixing part 21, so that the first fixing part 21 has a total of four holes.

[0047] The riser body 30 has a second fixing part 31, a sleeve part 32, and a working channel 33. The second fixing part 31 and the sleeve part 32 are respectively disposed at two ends of the riser body 30. The second fixing part 31 is used to assemble the handlebar 20, and the sleeve part 32 is used to assemble the front fork riser. There is an included angle θ between the second fixing part 31 and the sleeve part 32, which is 95 degrees, so that the second fixing part 31 is inclined upward relative to the sleeve part 32. The working channel 33 is formed in the second fixing part 31 and connects the sleeve part 32 to the external environment.

[0048] One end of the second fixing part 31 forms a connecting groove 311 and two locking grooves 312. These locking grooves 312 are located on both sides of the working channel 33, recessed inward from the surface of the connecting groove 311 for a certain distance, and then forming an internal thread. The connecting groove 311 has an arc-shaped surface, and its shape is mainly designed to fit the outer peripheral surface of the first fixing part 21 of the handlebar 20. The connecting groove 311 is divided into an upper arc segment 3111 and a lower arc segment 3112 from the central axis of the second fixing part 31. The circumference of the upper arc segment 3111 is smaller than that of the lower arc segment 3112, so that the lower arc segment 3112 extends further outward than the upper arc segment 3111. Therefore, when the handlebar 20 is placed in the connecting groove 311, the connecting groove 311 will cover most of the first fixing part 21 of the handlebar 20. Furthermore, in the cross-sectional view, the two opposite ends of the connecting groove 311 are connected to form an axis X. It can be seen that this axis X has exceeded the center point C of the first fixing part 21, which means that the circumference of the arc-shaped surface of the connecting groove 311 exceeds half of the circumference of the first fixing part 21. Thus, the handlebar 20 can be stably placed in the connecting groove 311 without easily falling off.

[0049] The connecting assembly 40 has a gasket body 41 and a connecting structure 42. The gasket body 41 has an arc-shaped shape corresponding to the shape of the first fixing part 21 of the handlebar 20, and the gasket body 41 has two locking holes 411 that penetrate the gasket body 41. The connecting structure 42 includes two locking elements 421, which can be bolts as locking elements 421. The surface of the locking element 421 has external threads.

[0050] When assembling the bicycle handlebar assembly 10, the operator only needs to hold the pad body 41 with one hand and make the pad body 41 abut against and fit against the first fixing part 21 of the handlebar 20, and hold the locking element 421 with the other hand to pass through the locking hole 411 and the through hole 211 of the first fixing part 21, and then lock the locking element 421 into the locking groove 312 of the second fixing part 31 of the vertical tube body 30 to fix the position of the handlebar 20. The whole assembly process is quite easy.

[0051] In addition, please refer to Figure 5 The gasket body 41 of this utility model can also be provided with an accessory bracket 412. The accessory bracket 412 extends from one end of the gasket body 41. The accessory bracket 412 serves as a mounting platform and is provided with multiple fixing holes, allowing the instrument device 50 to be mounted on the accessory bracket 412. This allows the rider to view the information displayed on the instrument device 50 during riding. Moreover, even with the instrument device 50 installed, the handlebars 20 still have a flat appearance and will not affect the drag coefficient or overall appearance due to the instrument device 50.

[0052] In summary, the bicycle handlebar assembly 10 provided by this utility model has at least the following advantages compared with the prior art:

[0053] 1. The bicycle handlebar assembly 10 provided by this utility model utilizes the structure of the handlebar 20 itself to form a first fixing part 21, so that the connecting component 40 can fix the handlebar 20 through the first fixing part 21 and the second fixing part 31 of the vertical tube body 30. It achieves a firm fixing effect with a simple structure, which can prevent the handlebar 20 from rotating due to external force and improve the safety of riding.

[0054] 2. The bicycle handlebar assembly 10 provided by this utility model has an arc-shaped connecting groove 311 formed in the vertical tube body 30. When the handlebar 20 is installed, the connecting groove 311 covers most of the outer peripheral surface of the first fixing part 21. In this way, even if the handlebar 20 is not completely fixed, it can still be kept in the connecting groove 311, avoiding it from falling off from the connecting groove 311 during the installation process, and increasing the convenience of installation for operators.

[0055] Finally, it must be stated again that the constituent elements disclosed in the above embodiments of this utility model are merely illustrative examples and are not intended to limit the scope of protection of this utility model. Substitutions or variations of other equivalent elements should also be within the scope of protection of this utility model.
