Description

Technical Field

[0001] The utility model relates to a bicycle, and more particularly to an integrated welded handlebar assembly. The handlebar has a special structure capable of accommodating and welding a stem tube body, so that the handlebar and the stem tube body present an integrated structure. Background Art

[0002] First of all, the stem of a bicycle is commonly known as the stem. It serves as a connecting component between the handlebars and the front fork stem. The stem can also provide different angle specifications, so that the fixed position of the handlebars can be higher or lower than the horizontal position of the stem to suit different riding postures.

[0003] The stem serves as an adapter component, with one end fitting the horizontal handlebar and the other end fitting the straight front fork stem. For example, Taiwan Patent Publication No. M294472 provides a bicycle handlebar stem that improves grip. The stem allows the handlebar to be placed in the arcuate groove of the stem's C-shaped clamp. The end cap is then closed and screwed to the C-shaped clamp, which forces the end cap against the C-shaped clamp, clamping the handlebar between the end cap and the C-shaped clamp. However, over time, the screws securing the end cap to the C-shaped clamp inevitably loosen, weakening the clamping force. If the rider applies excessive force to the handlebar, the handlebar may rotate, causing inconvenience during riding.

[0004] Furthermore, to understand their current riding conditions, many riders also install instrumentation on their bicycles to monitor information such as speed, RPM, or heart rate. Taiwan Patent Publication No. M506757 discloses a bicycle instrument mounting device. The mounting port and the stem mount are located at either end of the bracket. The mounting port is used to mount the instrument, while the stem mount is fixed to the straight handlebar of the bicycle to allow the rider to view the instrument information. While this structure can secure the instrument, its attachment to one side of the handlebar not only shifts the center of gravity of the handlebar, but the protrusion of the instrument from the handlebar also increases wind resistance during riding.

[0005] Therefore, the inventors have been thinking about how to provide a structure that can increase the bonding strength between the handlebar and the stem to prevent the handlebar from loosening, and provide a platform for installing instrument equipment so that the instrument equipment can be smoothly integrated into the handlebar and the stem. Utility Model Content

[0006] In view of the many shortcomings of the above-mentioned existing bicycles, the main purpose of the present invention is to provide an integrated welded handlebar assembly, which combines the handlebars and the stem body by welding and provides a platform for installing instrument equipment, so that the welded handlebar assembly has a high-strength structure and a smooth appearance.

[0007] To achieve the aforementioned primary objectives, the present invention provides an integrated welded handlebar assembly comprising a handlebar and a riser body. The handlebar has a groove and a surrounding wall formed around the groove. The riser body has a connecting portion at one end and a sleeve at the other end. The connecting portion comprises a base, two sidewalls disposed on either side of the base, and a mounting space formed between the base and the sidewalls. The connecting portion of the riser body is received in the groove of the handlebar, and the base and outer surfaces of the sidewalls of the connecting portion are welded to the surrounding wall of the handlebar.

[0008] Through the above-mentioned technical features, a groove is formed in the upper half of the handlebar to accommodate the connecting portion of the stem body. The connecting portion can be welded to the annular wall, so that the handlebar and the stem body form an integrated structure, which can solve the problem of the handlebar and the stem body being easily loose at the connection. The connecting portion has a reserved installation space for providing installation of instrument equipment. In this way, the instrument equipment does not need to be installed separately on one side of the handlebar, but is fully integrated into the welded handlebar assembly, achieving a streamlined and smooth appearance and reducing wind resistance during riding.

[0009] Preferably, the bottom surface of the base of the connecting portion of the riser body is a flat surface, and the connecting portion abuts against the handlebar wall via the flat surface. Therefore, the riser body can be placed flat on the handlebar wall via the connecting portion, facilitating welding and improving the stability of the connection between the riser body and the handlebar.

[0010] Preferably, the connection portion of the riser body further includes a lip formed on the bottom surface of the base. The lip is arcuately shaped to correspond to the shape of the handlebar's side without the groove. The lip is welded to the handlebar's side without the groove. Thus, the lip partially covers the lower half of the handlebar, providing a larger connection area between the riser body and the handlebar, effectively enhancing the strength of the connection.

[0011] Preferably, the handlebar is a hollow tube, with the annular wall formed on the periphery of the groove. Therefore, the groove and the annular wall are cut out of the hollow handlebar, and the connecting portion of the riser body can be placed flat on the annular wall on the periphery of the groove.

[0012] Preferably, the handlebar is a hollow tube, and after stamping, the annular wall surrounds the groove. Therefore, the hollow handlebar can be directly stamped to form the groove and the annular wall without the need for cutting, thereby preserving the complete structure of the handlebar.

[0013] The detailed structure, features, assembly, and usage of the integrated welded handlebar assembly provided by the present invention will be described in the detailed description of the following embodiments. However, those skilled in the art will appreciate that the detailed description and the specific embodiments listed in the following embodiments are merely illustrative of the present invention and are not intended to limit the scope of the patent application for the present invention.

[0038] See also Figures 1 to 4 The integrated welded handlebar assembly 10 of the present invention mainly includes a handlebar 20 and a vertical tube body 30.

[0039] The handlebar 20 has a groove 21 and an annular wall 22 adjacent to the groove 21. The form of the handlebar 20 is not limited to a flat handle or a curved handle, nor is it limited to a hollow handlebar 20 or a solid handlebar (not shown). The groove 21 is a straight tube formed between the grips on both sides of the handlebar 20, that is, the upper half is located in the center of the handlebar 20, and the lower half maintains the arc shape of the straight tube. After the groove 21 is formed, the groove 21 is surrounded by the annular wall 22. The groove 21 of the handlebar 20 mainly provides space for accommodating the vertical tube body 30, and the annular wall 22 provides a support position for the vertical tube body 30 when it is accommodated in the groove 21. If a hollow handlebar 20 is selected, the annular wall 22 is only formed on the periphery of the groove 21, such as Figure 2 Also, or directly punching the straight tube of the hollow handlebar 20, so that the central position of the handlebar 20 is recessed to form a platform, this form of the handlebar 20 of the annular wall 22 surrounds the groove 21, such as Figure 3 shown.

[0040] The vertical tube body 30 has a connecting portion 31 and a sleeve portion 32. The connecting portion 31 is provided at one end of the vertical tube body 30, and the sleeve portion 32 is provided at the other end of the vertical tube body 30. The connecting portion 31 of the vertical tube body 30 has a base 311, two side walls 312 and an installation space 313. The two side walls 312 are respectively provided on both sides of the base 311, and the installation space 313 is jointly formed between the base 311 and the two side walls 312. Since the bottom surface of the base 311 of the connecting portion 31 is flat, when the connecting portion 31 of the vertical tube body 30 is accommodated in the groove 21 of the handlebar 20, it can be placed flat on the annular wall 22 of the handlebar 20 through the flat surface of the connecting portion 31. Then, the base 311 and the outer surfaces of the two side walls 312 of the connecting portion 31 are welded to the annular wall 22 of the handlebar 20. The welding is performed along the circumference of the annular wall 22, as shown in FIG. Figure 4 shown.

[0041] In this way, the stem body 30 is fixed to the handlebar 20 via the connecting portion 31 , so that the handlebar 20 and the stem body 30 are combined into a one-piece welded handlebar assembly 10 . This prevents the handlebar 20 from becoming loose at the connection between the stem body 30 and the stem body 30 . Furthermore, since the handlebar 20 has the groove 21 , the stem body 30 is sunk into the groove 21 and then welded to the handlebar 20 . The height of the stem body 30 only slightly exceeds that of the handlebar 20 , giving the welded handlebar assembly 10 a smooth appearance.

[0042] Please also refer to Figure 5 The mounting space 313 of the connecting portion 31 of the riser body 30 is used to set the mounting seat 41 of the instrument device 40 or to directly mount the instrument device 40, while the sleeve portion 32 is used to be sleeved on the front fork stem of the bicycle (not shown) to apply the welded handlebar assembly 10 to the bicycle. The top side and surrounding area of ​​the sleeve portion 32 can be covered by an outer cover sheet 33 to prevent the components of the sleeve portion 32 from being exposed, giving the sleeve portion 32 a streamlined and flat appearance. In this embodiment, the instrument device 40 can be integrated into the mounting space 313 of the stem body 30 , eliminating the need for the rider to install an additional instrument device 40 on the left or right side of the handlebar 20 . The installed instrument device 40 is located in the center of the handlebar 20 , thereby preventing the weight of the instrument device 40 from affecting the handlebar 20 and causing a shift in the center of gravity. The rider can also conveniently view current riding information directly through the instrument device 40 while riding, eliminating the need to shift the line of sight to the left or right side of the handlebar 20 to view the instrument device 40 , thereby avoiding accidents caused by line of sight deviation. It can be seen that the structural design of the welded handlebar assembly 10 also improves riding safety. Furthermore, the instrument device 40 and the welded handlebar assembly 10 form a flat appearance, which not only maintains a simple appearance of the entire bicycle, but also avoids increasing wind resistance while riding the bicycle without affecting riding efficiency.

[0043] Also, see Figures 6 to 8 The connecting portion 31 of the vertical tube body 30 also has a lip 314, which is formed by extending outward from the bottom surface of the base 311. The shape of the lip 314 is designed according to the lower half of the handlebar 20 without the groove 21, that is, it is formed into an arc according to the straight tube shape of the handlebar 20 to fit the lower half of the handlebar 20. When welding, in addition to welding along the periphery of the annular wall 22, welding is also performed along the periphery of the lip 314, so that the vertical tube body The connection between the connection portion 31 and the handlebar 20 extends to the lower half of the handlebar 20. In this way, the riser body 30 is not only welded to the handlebar 20 through the bottom surface of the base 311, but also welded to the side and bottom of the handlebar 20 through the lip portion 314. By increasing the welding area between the connection portion 31 and the handlebar 20, the connection strength between the riser body 30 and the handlebar 20 is improved, and the riser body 30 is more firmly fixed to the handlebar 20.

[0044] In summary, the integrated welded handlebar assembly 10 provided by the present invention has at least the following advantages compared to the prior art:

[0045] 1. The integrated welded handlebar assembly 10 of the present invention welds the handlebar 20 to the stem body 30 to form a one-piece structure. This prevents the handlebar 20 from becoming loose from the stem body 30 , and the handlebar 20 and stem body 30 remain firmly connected even after prolonged use.

[0046] 2. In the integrated welded handlebar assembly 10 of the present invention, the connecting portion 31 of the riser body 30 can be positioned within the recess 21 of the handlebar 20 and welded to the annular wall 22. The connecting portion 31 also provides a mounting space 313 for integrating the instrument panel 40 into the welded handlebar assembly 10. This gives the welded handlebar assembly 10 a streamlined and smooth appearance, making it easier for the rider to view the information on the instrument panel 40. This not only improves riding safety but also reduces the cost of installing an additional mounting bracket for the instrument panel 40.

[0047] Finally, it must be stated again that the constituent components disclosed in the above embodiments of the present invention are for illustration only and are not intended to limit the scope of the present invention. Replacements or changes of other equivalent components should also be covered by the scope of the patent application of the present invention.
