Description

Technical Field

[0001] The utility model relates to the technical field of bicycle accessories, in particular to an integrated handlebar and a scooter. Background Art

[0002] In modern bicycle design, the function of handlebars has expanded from simple control to the integration of multiple accessories, such as stopwatches, hydraulic brakes, etc., to provide a richer riding experience and more convenient operation.

[0003] However, in order to meet the aesthetic requirements, traditional handlebar designs often need to add grooves in the middle of the handlebar to accommodate accessories such as a computer and a brake. Although this design meets the functional requirements to a certain extent, it also brings a series of problems: first, the groove in the middle of the handlebar will weaken the overall strength of the handlebar, making it more likely to break when subjected to greater force; second, due to the presence of the groove, the stress point of the handlebar changes, which may cause stress concentration during riding, further increasing the risk of handlebar breakage. The breakage of the handlebar will not only threaten the safety of the rider, but may also cause traffic accidents, bringing serious safety hazards to the rider and others. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model.

[0040] Reference Figure 1-Figure 3 , an integrated handlebar, comprising: a central module 1, a left module 2, a right module 3, a left plug-in module (not shown in the figure) and a right plug-in module (not shown in the figure);

[0041] The central module 1 is disposed between the left module 2 and the right module 3, and the central module 1 can be used for installation of the vertical pipe 4;

[0042] The left module 2 is arranged on the left side of the central module 1, and the left module 2 is used for the rider's left hand to grasp;

[0043] The right module 3 is arranged on the right side of the central module 1, and the right module 3 is used for the rider to grab with his right hand;

[0044] The left plug-in module and the central module 1 or the left plug-in module and the left module 2 are integrally formed, and a left slot (not shown in the figure) for the left plug-in module to be inserted is provided on the left module 2 or the central module 1;

[0045] The right plug-in module and the central module 1 or the right plug-in module and the right module 3 are integrally formed, and a right slot (not shown in the figure) for the right plug-in module to be inserted is provided on the right module 3 or the central module 1.

[0046] By matching the left plug-in module with the left slot and the right plug-in module with the right slot, the central module 1, the left module 2 and the right module 3 can be connected more tightly and stably, thereby improving the rigidity of the entire handlebar structure;

[0047] In addition, since the center module 1, the left module 2, and the right module 3 are arranged separately, the left plug-in module cooperates with the left slot, and the right plug-in module cooperates with the right slot, which can optimize the stress distribution, avoid the connection between the center module 1 and the left module 2, and the connection between the center module 1 and the right module 3 during riding, breakage, and safety hazards, thereby improving the stability of the handlebar structure.

[0048] Furthermore, the left plug-in module and the right plug-in module are integrally formed with the central module 1, the left module 2 is provided with a left slot for the left plug-in module to be inserted into, and the right module 3 is provided with a right slot for the right plug-in module to be inserted into;

[0049] The central module 1 and the left plug-in module are both welded and connected to the left module 2;

[0050] The central module 1 and the right plug-in module are both connected to the right module 3 by welding.

[0051] Compared with other fixing methods, such as bolt connection, welding does not need to set holes on the handlebars for screw insertion, so as to avoid stress concentration in the holes and fatigue fracture; moreover, welding can enhance the connection strength between the central module 1, the left plug-in module and the left module 2, and enhance the connection strength between the central module 1, the right plug-in module and the right module 3, further improving the stability of the handlebar structure.

[0052] Specifically, the structural strength of the central module 1 is greater than the structural strengths of the left module 2 and the right module 3 .

[0053] Specifically, the handlebar is a curved handlebar;

[0054] The left module 2 includes a left parallel portion 22, a left connecting portion 23 and a left lower curved portion 24;

[0055] The right module 3 includes a right parallel portion 32, a right connecting portion 33 and a right downward bending portion 34;

[0056] The distances of the left parallel portion 22, the left connecting portion 23 and the left lower curved portion 24 relative to the central module 1 are arranged in order from near to far;

[0057] The wall thickness of the left connecting portion 23 is smaller than the wall thickness of the left parallel portion 22 and the left lower curved portion 24;

[0058] The right parallel portion 32, the right connecting portion 33 and the right lower curved portion 34 are arranged in order from near to far relative to the central module 1;

[0059] The wall thickness of the right connecting portion 33 is smaller than the wall thickness of the right parallel portion 32 and the right downwardly bent portion 34 .

[0060] Reference Figure 1-Figure 3The left connecting portion 23 in the left module 2 and the right connecting portion 33 in the right module 3 are the places where the shapes of the left module 2 and the right module 3 change sharply, which are stress concentration areas of the handlebar. Fatigue cracks usually begin to form in stress concentration areas. By adopting a thinning setting in the left connecting portion 23 and the right connecting portion 33, the left connecting portion 23 and the right connecting portion 33 can be used as stress release areas, allowing the left connecting portion 23 and the right connecting portion 33 to be locally deformed when the handlebar is in use when subjected to load, and can guide the load to be transferred to the left lower curved portion 24 and the right lower curved portion 34, thereby avoiding stress concentration in the left connecting portion 23 and the right connecting portion 33 and improving the fatigue life of the handlebar.

[0061] Preferably, the central module 1 is made by a 3D printing forging process, and the left module 2 and the right module 3 are special-shaped tubes made by a water injection process.

[0062] Specifically, brake handles are installed above the left connecting portion 23 and the right connecting portion 33 .

[0063] Specifically, the left parallel portion 22 and the right parallel portion 32 are hollow and flat, and the left downward curved portion 24 and the right downward curved portion 34 are hollow and cylindrical.

[0064] The hollow settings of the left parallel portion 22, the right parallel portion 32, the left lower curved portion 24, and the right lower curved portion 34 can reduce the use of materials for manufacturing the handlebars and reduce the gravity of the handlebars; and the hollow structure reduces the local thickness of the material, so that the stress is more evenly distributed on the cross section of the material, reducing the local stress peak.

[0065] The central module 1 is arranged in a "T" shape.

[0066] Furthermore, an open slot 11 is provided on the central module 1. The open slot 11 can be used to install bicycle accessories such as an oil pan, an oil reservoir, and a speed meter.

[0067] A mobility scooter has the above-mentioned integrated handlebar.

[0068] Furthermore, the vehicle for commuting is a mountain bike or a road bike.

[0069] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
