[0021] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0022] As used herein, the term "including" and its variations represent open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based at least in part on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment."

[0023] As described above, the frames of current two-wheeled vehicles are all steel tube frames. The manufacturing process of steel tube frames is time-consuming and labor-intensive, resulting in low production efficiency of the frames. The embodiments of the present disclosure provide a two-wheeled vehicle and its frame, which can improve the production efficiency of the two-wheeled vehicle frame and save manpower. Figures 1 to 7 The principles of the present disclosure are described.

[0024] Figure 1 A perspective schematic diagram of a frame 100 of a two-wheeled vehicle and a basket 200 mounted on the frame 100 according to some embodiments of the present disclosure is shown. Figure 2 A cross-sectional view taken along a longitudinal center plane of the frame 100 and the basket 200 is shown. Figures 3 to 5 Schematic diagrams of the exploded view of the frame 100 and the basket 200 when viewed from different angles are shown. Figure 6 and Figure 7 Schematic diagrams of the structure of the frame 100 when viewed from different viewing angles are shown.

[0025] See also Figure 1 and Figure 2 The frame 100 of the two-wheeled vehicle includes a main body shell 10 and a front windshield shell 20. The main body shell 10 and the front windshield shell 20 may be integrally formed. The front windshield shell 20 may be mounted on the main body shell 10 in any suitable manner to form the two-wheeled vehicle frame 100. In addition, a basket 200 of the two-wheeled vehicle may be mounted on the front windshield shell 20.

[0026] Specifically, the main body shell 10 includes a head portion 11, a pedal support portion 12 and a rear portion 13. The pedal support portion 12 is used to support the pedal. The head portion 11 extends upward from the front end of the pedal support portion 12, and the head portion 11 has a mounting hole 110 for the handlebar shaft (not shown in the figure, that is, the rotating shaft of the handlebar) to pass through. The rear portion 13 extends upward from the rear end of the pedal support portion 12, and the top of the rear portion 13 corresponds to the saddle of the two-wheeled vehicle. The main body shell 10, as the main structure of the frame 100, can be integrally formed by die-casting of metal materials, thereby ensuring the structural strength and load-bearing capacity of the frame 100.

[0027] It should be noted that, unless otherwise specified, directional terms such as "front," "rear," "left," and "right" with respect to the frame 100 in the embodiments of the present disclosure refer to the front, rear, left, and right directions of a two-wheeled vehicle having the frame 100 in a normal riding state. These directional terms are used solely to clarify the description of the embodiments of the present disclosure and are not intended to unduly limit the scope of protection of the present disclosure.

[0028] A front windshield housing 20 is fixed to the top of the vehicle's front end 11. It has a hollow cavity 201 through which the handlebar shaft passes. While shielding the handlebar shaft and blocking wind, it also connects to the basket 200, facilitating its installation on the vehicle frame 100. The front windshield housing 20 can be integrally formed from a metal material, for example, through die-casting. This allows it to withstand significant impact without causing damage or deformation, while also reliably supporting the basket 200 and transferring its load to the main housing 10.

[0029] In some embodiments, the material of the main body housing 10 may be, but is not limited to, a lightweight alloy (e.g., aluminum alloy or magnesium alloy). The material of the front windshield housing 20 may be, but is not limited to, a lightweight alloy (e.g., aluminum alloy or magnesium alloy). Using aluminum alloy or magnesium alloy to manufacture the main body housing 10 and the front windshield housing 20 can ensure the structural strength of the vehicle frame 100 while making the vehicle frame 100 relatively light.

[0030] In some embodiments, the main body shell 10 and the front windshield shell 20 can be integrally formed using a process other than the die-casting process, and the materials of the main body shell 10 and the front windshield shell 20 are not limited to aluminum alloy and magnesium alloy.

[0031] The vehicle frame 100 provided in the embodiment of the present disclosure facilitates mechanized mass production of the main body shell 10 and the front windshield shell 20. Furthermore, the process of assembling the main body shell 10 and the front windshield shell 20 into the vehicle frame 100 is more time-saving and labor-saving than the prior art process of welding a plurality of steel pipe prefabricated parts into a vehicle frame, thereby helping to improve the production efficiency of the vehicle frame 100.

[0032] See also Figures 3 to 5 , which shows an exemplary mounting structure of the main body housing 10 and the front windshield housing 20.

[0033] Specifically, a mounting platform 111 is provided at the top of the vehicle head 11. The mounting platform 111 is arranged at an angle, with the front being higher and the back being lower. In some embodiments, the mounting platform 111 is, for example, quadrilateral, more specifically, rectangular or trapezoidal. An upwardly extending frame head tube 112 is provided on the mounting platform 111. The center hole of the frame head tube 112 forms the mounting hole 110, that is, the mounting hole 110 is provided on the frame head tube 112. In some embodiments, the centerline of the mounting hole 110 is perpendicular to the mounting platform 111. A forward-extending first positioning post 141 is provided on the frame head tube 112. The first positioning post 141 has a center hole. In some embodiments, the centerline of the center hole of the first positioning post 141 is perpendicular to the centerline of the mounting hole 110. In some embodiments, the first positioning post 141 is closer to the top of the frame head tube 112 and farther away from the mounting platform 111.

[0034] It should be noted that the upward extension and downward extension in the embodiments of the present disclosure are not limited to extending upward or downward in a direction perpendicular to the ground. The upward extension may be an upward extension at an angle, and the downward extension may be an downward extension at an angle. Similarly, the forward extension and rearward extension in the embodiments of the present disclosure are not limited to extending forward or rearward in a direction parallel to the ground. The forward extension may be an upward extension at an angle, and the rearward extension may be an rearward extension at an angle.

[0035] The front windshield housing 20 includes a bottom opening 202, a top opening 203, and sidewalls 21. In some embodiments, the sidewalls 21 include, for example, a front sidewall 211, a rear sidewall 212, a left sidewall 213, and a right sidewall 214, and the hollow cavity 201 is primarily defined by the sidewalls 21. In some embodiments, the bottom of the sidewalls 21 define the bottom opening 202. In some embodiments, the top of the sidewalls 21 define the top opening 203. In some embodiments, a cover portion 216 is provided at the top of the sidewalls 21, and the top opening 203 is located in the middle of the cover portion 216. In some embodiments, an annular flange 2161 is provided on the cover portion 216, and the annular flange 2161 is arranged around the periphery of the top opening 203.

[0036] The bottom opening 202 of the front windshield shell 20 is buckled onto the mounting platform 111, and the mounting platform 111 can close the bottom opening 202. At least a portion of the frame head tube 112 is located in the hollow cavity 201. Figure 2 and Figure 6 In some embodiments, the top end of the frame head tube 112 protrudes upward relative to the top opening 203 , and an accommodation gap is provided between the outer peripheral wall of the frame head tube 112 and the peripheral wall of the top opening 203 .

[0037] See also Figure 3 and Figure 4 The front sidewall 211 of the sidewall 21 is provided with a first positioning hole 2110, which corresponds to the first positioning post 141. The first positioning hole 2110 is, for example, a circular hole. The first fastener 31 passes through the first positioning hole 2110 and connects with the center hole of the first positioning post 141, thereby securing the front windshield housing 20 and the main body housing 10 together. In some embodiments, the rear sidewall of the basket 200 is provided with a hole 20a. The first fastener 31 passes through the hole 20a and the first positioning hole 2110, and then connects with the center hole of the first positioning post 141. In other words, the first fastener 31 is also used to secure the basket 200 to the frame 100. In some embodiments, the first fastener 31 is, for example, a screw.

[0038] See also Figure 3 and Figure 7A second positioning hole 1112 and a third positioning hole 1113 are respectively provided on the left and right sides of the front end of the mounting platform 111. In the left-right direction of the mounting platform 111, the frame head tube 112 is located between the second positioning hole 1112 and the third positioning hole 1113. The second positioning hole 1112 is, for example, an elongated hole extending in the front-to-back direction. The third positioning hole 1113 is, for example, a circular hole. In some alternative embodiments, the second positioning hole 1112 is, for example, a circular hole, and the third positioning hole 1113 is, for example, an elongated hole extending in the front-to-back direction.

[0039] See also Figure 4 The bottom of the front windshield housing 20 is provided with a second positioning column 142 and a third positioning column 143, and the second positioning column 142 and the third positioning column 143 are, for example, located in the hollow cavity 201. The second positioning column 142 corresponds to the second positioning hole 1112, and the second fastener 32 passes through the second positioning hole 1112 and is connected to the center hole of the second positioning column 142. The third positioning column 143 corresponds to the third positioning hole 1113, and the third fastener 33 passes through the third positioning hole 1113 and is connected to the center hole of the third positioning column 143. The second fastener 32 and the third fastener 33 are, for example, screws. With reference to Figure 7 , the first fastener 31 , the second fastener 32 and the third fastener 33 form a triangular fastening design.

[0040] See also Figure 3 and Figure 5 In some embodiments, upwardly extending bosses 1114 are respectively provided on the left and right sides of the front end of the mounting platform 111 , and the second positioning hole 1112 and the third positioning hole 1113 are respectively provided in the corresponding bosses 1114 .

[0041] See also Figure 5In some embodiments, the rear sidewall 212 of the sidewall 21 is provided with a downwardly extending flange 2121. A fourth positioning hole 2124 and a fifth positioning hole 2125 are provided on the left and right sides of the flange 2121, respectively. The fourth positioning hole 2124 and the fifth positioning hole 2125 are, for example, circular holes. The head section 11 is provided with a fourth positioning post 114 and a fifth positioning post 115, which are located below the mounting platform 111. The head tube 112 is located between the fourth positioning post 114 and the fifth positioning post 115 in the left-right direction of the mounting platform 111. The fourth positioning post 114 corresponds to the fourth positioning hole 2124, and the fourth fastener 34 passes through the fourth positioning hole 2124 and connects to the center hole of the fourth positioning post 114. The fifth positioning post 115 corresponds to the fifth positioning hole 2125, and the fifth fastener 35 passes through the fifth positioning hole 2125 and connects to the center hole of the fifth positioning post 115. The fourth fastening member 34 and the fifth fastening member 35 are, for example, screws. The second fastening member 32, the third fastening member 33, the fourth fastening member 34 and the fifth fastening member 35 form a quadrangular fastening design.

[0042] In the embodiment of the present disclosure, the first fastener 31, the second fastener 32 and the third fastener 33 form a triangular fastening design, and the second fastener 32, the third fastener 33, the fourth fastener 34 and the fifth fastener 35 form a quadrilateral fastening design, so that the front windshield shell 20 and the main body shell 10 support each other to form a whole with high structural strength. The whole can bear the load of the vegetable basket 200 during use, thereby meeting the load requirements of the vegetable basket 200.

[0043] Continue to see Figure 5 The left and right sides of the frame head tube 112 are respectively connected to the mounting platform 111 via first connecting ribs 151. In some embodiments, the connecting ribs connecting the frame head tube 112 and the mounting platform 111 are not limited to the first connecting ribs 151. Each connecting rib can enhance the structural strength of the frame head tube 112.

[0044] See also Figure 3 and Figure 4Each first connecting rib 151 is provided with at least one forward-extending fixing post 1511, which is used to mount the basket 200. More specifically, each fixing post 1511 has a central hole and is parallel to the first positioning post 141. A through-hole 2116 is provided on the front sidewall 211, corresponding to the central hole of the fixing post 1511. A hole 20b is provided on the rear sidewall of the basket 200, corresponding to the through-hole 2116. Sixth fasteners 36 pass through corresponding holes 20b and 2116, then connect to the central hole of the corresponding fixing post 1511. The sixth fasteners 36 not only securely mount the basket 200 to the vehicle frame 100, but also strengthen the connection between the front windshield housing 20 and the main body housing 10.

[0045] Although in the above embodiment, the basket 200 is secured to the frame 100 via the first fastener 31 and the sixth fastener 36, in some alternative embodiments, the basket 200 may be secured to the frame 100 solely via the sixth fastener 36. Specifically, before mounting the basket 200 on the frame 100, the first fastener 31 may be inserted through the first locating hole 2110 and then connected to the center hole of the first locating post 141. When the basket 200 is secured to the frame 100 via the sixth fastener 36, the rear sidewall of the basket 200 may obscure the first fastener 31.

[0046] Return to see Figure 3 In some embodiments, each first connecting rib 151 is specifically provided with two fixing posts 1511. The two fixing posts 1511 are arranged one above the other and are respectively parallel to the first positioning posts 141. The first positioning posts 141 are located in the space defined by the four fixing posts 1511. Of course, in some alternative embodiments, the number of fixing posts 1511 on each first connecting rib 151 is not limited to two.

[0047] Continue to see Figure 3In some embodiments, the first positioning post 141 and at least some of the fixing posts 1511, as well as adjacent fixing posts 1511, are connected, for example, by second connecting ribs 152. At least some of the fixing posts 1511 (more specifically, the two fixing posts 1511 located at the bottom) are connected to the corresponding first connecting ribs 151, for example, by third connecting ribs 153, which extend downward to the mounting platform 111. The first positioning post 141 is connected to the frame head tube 112, for example, by fourth connecting ribs 154, which extend downward to the mounting platform 111. The provision of these connecting ribs not only improves the structural strength of the frame head tube 112 but also effectively ensures the structural strength of the first positioning post 141 and each fixing post 1511. Furthermore, the connection between the front windshield housing 20 and the main body housing 10 ensures that the structure in this area has sufficient structural strength, thereby meeting not only the load requirements of the vegetable basket but also the strength requirements required for abnormal impact.

[0048] In this embodiment, the main housing 10 and the front windshield housing 20 are integrally formed metal components. To ensure the structural strength of the vehicle frame 100, the main housing 10 and the front windshield housing 20 must not deform to accommodate errors during installation. To ensure smooth installation of the front windshield housing 20 to the main housing 10, the shapes and dimensions of the first through fifth locating holes 2110, 2125 were further designed through dimensional chain analysis and calculation of the vehicle frame 100.

[0049] Specifically, the first positioning hole 2110 serves as a reference point in the front-to-back direction, and the oblong hole of the second positioning hole 1112 serves as a reference point in the up-down and left-to-right directions. Furthermore, the diameter of the first positioning hole 2110 is larger than the axial diameter of the first fastener 31, so that the first positioning hole 2110 and the first fastener 31 are loosely fitted. The diameter of the third positioning hole 1113 is larger than the axial diameter of the third fastener 33, so that the third positioning hole 1113 and the third fastener 33 are loosely fitted. The diameter of the fourth positioning hole 2124 is larger than the axial diameter of the fourth fastener 34, so that the fourth positioning hole 2124 and the fourth fastener 34 are loosely fitted. The diameter of the fifth positioning hole 2125 is larger than the axial diameter of the fifth fastener 35, so that the fifth positioning hole 2125 and the fifth fastener 35 are loosely fitted. In this way, the first positioning hole 2110, the fourth positioning hole 2124 and the fifth positioning hole 2125 can absorb errors in the up and down directions and the left and right directions, the second positioning hole 1112 can absorb errors in the front and back directions, and the third positioning hole 1113 can absorb errors in the front and back directions and the left and right directions, thereby ensuring the smooth assembly of the front windshield shell 20 and the main body shell 10.

[0050] It should be noted that, in some alternative embodiments, the front windshield housing 20 may also be connected to the main body housing 10 via additional fasteners.

[0051] As can be seen from the above, in some alternative embodiments, the oblong hole of the second positioning hole 1112 and the round hole of the third positioning hole 1113 can be interchanged. When the second positioning hole 1112 is a round hole and the third positioning hole 1113 is an oblong hole, the third positioning hole 1113 serves as a reference point in the vertical and horizontal directions and can absorb errors in the front-to-back direction. The second positioning hole 1112 and the second fastener 32 have a clearance fit, and the second positioning member 1112 can absorb errors in the front-to-back and horizontal directions.

[0052] Some embodiments of the present disclosure further provide a two-wheeled vehicle including a basket 200 and a frame 100 . As described above, the basket 200 can be fixed to the front side wall 211 of the front windshield shell 20 of the frame 100 at least by a sixth fastener 36 .

[0053] The two-wheeled vehicle and its frame 100 provided by the disclosed embodiments, including the front windshield housing 20 and the main body housing 10 of the frame 100, can be mechanized and mass-produced. Furthermore, the front windshield housing 20 and the main body housing 10 can be assembled together using multiple fasteners, saving time and effort during the assembly process and facilitating improved production efficiency of the frame 100. Furthermore, the positions of the multiple fasteners are designed to meet the assembly requirements of the front windshield housing 20 and the main body housing 10, ensuring the structural strength requirements of the assembled frame 100, while also meeting the load requirements of the vegetable basket 200 and the impact resistance requirements of the frame 100.

[0054] While various embodiments of the present disclosure have been described above, the above descriptions are illustrative, non-exhaustive, and not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
