Description

Technical Field

[0001] This utility model belongs to the technical field of motorcycle parts and relates to a mounting bracket for a motorcycle handlebar. Background Technology

[0002] Motorcycle handlebar mounts connect the handlebars to the bottom steering shaft, allowing the rider to control the motorcycle's steering. Existing mounts typically consist of an aluminum mounting base and studs. During production, the aluminum mounting base is first die-cast. After drilling holes in the aluminum mounting base, M10 threaded holes are tapped, and then the double-ended stud is screwed into the threaded holes to connect with the aluminum mounting base.

[0003] However, the existing mounting base has some shortcomings. In the mounting base structure manufactured in the above way, the root of the threaded connection between the mounting aluminum base and the double-ended stud is the weak point of stress. Since the root of the thread is machined, the stress at the root is equivalent to that of a 9mm outer diameter steel bar, and there is machined stress, which makes it prone to fatigue fracture. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing a mounting bracket for a motorcycle handlebar. The technical problem to be solved by this utility model is: how to improve the connection strength between the mounting aluminum bracket and the stud.

[0005] The purpose of this utility model can be achieved through the following technical solution: a mounting base for a motorcycle handlebar, including a mounting aluminum base, the top of which is provided with a downwardly recessed mounting groove, and the bottom of which is provided with a stud, the stud consisting of a top screw and a bottom thread, the screw being integrally die-cast inside the mounting aluminum base.

[0006] In this design, a threaded structure is only installed at the bottom of the stud for connection to the bottom steering structure. A screw structure is installed at the top of the stud, connecting to the mounting aluminum base. Furthermore, the manufacturing process of the mounting aluminum base is improved. Before die-casting, the stud structure is placed in advance, allowing the screw at the top of the stud to enter the die-casting cavity. After the molten aluminum cools and solidifies, it encloses the stud on the inside. This method reduces drilling, tapping, and stud assembly processes, improving production efficiency. The overall stress of the mounting aluminum base is now borne by the screw, avoiding stress on the thread root and thus increasing the overall strength of the mounting aluminum base.

[0007] In the aforementioned motorcycle handlebar mounting bracket, the outer diameter of the screw is larger than the outer diameter of the thread. Specifically, the outer diameter of the screw is 12mm, which, being larger than the M10 thread, improves the structural strength of the screw and increases the overall strength of the mounting bracket by more than 50%.

[0008] In the aforementioned motorcycle handlebar mounting bracket, the bottom of the mounting aluminum bracket is provided with a downwardly extending connecting portion, which encloses the screw on the inside.

[0009] In the aforementioned motorcycle handlebar mounting bracket, the top of the mounting aluminum base has two screw holes, located on both sides of the mounting groove. The screw holes engage with bolts, allowing the top of the mounting aluminum base to be connected to the mounting bracket.

[0010] In the aforementioned motorcycle handlebar mounting bracket, the mounting groove has a semi-circular structure. The semi-circular structure of the mounting groove is designed to fit snugly against the bottom of the handlebar.

[0011] In the aforementioned motorcycle handlebar mounting bracket, the top of the mounting aluminum base is provided with a bolt-connected upper mounting bracket. The bottom of the upper mounting bracket is provided with a downward-opening semi-circular mounting groove. The bottom mounting groove of the upper mounting bracket can be combined with the mounting groove at the top of the mounting aluminum base to form a circular mounting hole, which can clamp the motorcycle handlebar inside. When the handlebar is rotated, it can drive the mounting aluminum base to rotate together.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this solution, the aluminum mounting base and stud are die-cast, which reduces the processes of drilling, tapping, and stud assembly, thus improving production efficiency. At this time, the stress of the overall structure of the aluminum mounting base is borne by the screw, avoiding the stress on the root of the thread, thereby improving the overall strength of the aluminum mounting base. Attached Figure Description

[0015] Figure 2 This is a frontal half-sectional structural diagram of the present invention.

[0016] In the diagram, 1 is the mounting aluminum base; 1a is the mounting groove; 1b is the screw hole; 1c is the connecting part; 2 is the stud; 2a is the screw rod; and 2b is the thread. Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] Example

[0019] like Figure 1As shown, a motorcycle handlebar mounting bracket includes a mounting aluminum base. The top of the mounting aluminum base has a downwardly recessed mounting groove with a semi-circular structure. The top of the mounting aluminum base has two screw holes located on both sides of the mounting groove. The screw holes are used for threaded connection to the upper mounting bracket at the top. The bottom of the mounting aluminum base has a stud.

[0020] like Figure 2 As shown, the stud consists of a top screw and a bottom thread. The outer diameter of the screw is larger than the outer diameter of the thread. The screw is integrally die-cast inside the mounting aluminum base. The bottom of the mounting aluminum base has a downwardly extending connecting part that wraps the screw inside.

[0021] The working principle of this solution is as follows: Figure 1-2 As shown, a 12mm outer diameter screw is used to connect to the mounting aluminum base. The production process of the mounting aluminum base is improved by pre-inserting the stud structure before die casting, so that the screw at the top of the stud enters the die casting cavity. After the molten aluminum cools and solidifies, it can wrap the stud inside, reducing drilling, tapping, stud assembly and other processes, thus improving production efficiency. At this time, the overall structure of the mounting aluminum base is stressed by the screw, avoiding the stress on the root of the thread, thereby improving the overall strength of the mounting aluminum base.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0023] Although this document frequently uses terms such as 1. mounting aluminum base; 1a. mounting groove; 1b. screw hole; 1c. connecting part; 2. stud; 2a. screw rod; 2b. thread, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
