[0093] To make the description of this disclosure more detailed and complete, reference may be made to the accompanying drawings and the various embodiments described below. The elements in the drawings are not drawn to scale and are provided for illustrative purposes only. Many practical details are described below to provide a comprehensive understanding of this disclosure; however, those skilled in the art will understand that this disclosure can be practiced without one or more of these practical details, and therefore, these details should not be used to limit this disclosure.

[0094] Please refer to Figure 1 . Figure 1 A schematic side view of a vehicle assembly system 12 according to an embodiment of this disclosure is shown. As shown, the vehicle assembly system 12 includes a central assembly platform 20, a first wheel assembly trolley 30A, and a second wheel assembly trolley 30B. The central assembly platform 20 is used to support a frame 13 (e.g., the frame of a bicycle, electric bicycle, or electric motorcycle) and includes a base 23 and a tilting mechanism 50 and a lifting mechanism 25 disposed on the base 23. The tilting mechanism 50 is configured to hold the frame 13 and can tilt the frame 13. The lifting mechanism 25 connects the base 23 and the tilting mechanism 50 and is configured to drive the tilting mechanism 50 to move up and down on the base 23. The first wheel assembly trolley 30A and the second wheel assembly trolley 30B are respectively configured to carry the first wheel assembly 19A and the second wheel assembly 19B, which may include wheels, shock absorbers, front forks, or rear swingarms. In this embodiment, the first wheel set 19A and the second wheel set 19B are the front wheel set and the rear wheel set, respectively. The front wheel set includes a front fork, and the front end of the frame 13 has a wrist rest through hole 15 into which the front fork can be inserted. The rear wheel set includes a rear swingarm, which can be fixed to the rear end of the frame 13.

[0095] The lifting mechanism 25 facilitates the installation of the first wheelset 19A and the second wheelset 19B onto the frame 13, and also makes it easier for the operator to install or remove the frame 13 from the tilting mechanism 50. Furthermore, since the wrist rest through-hole 15 of the frame 13 is generally angled, the tilting mechanism 50 can verticalize the wrist rest through-hole 15. Combined with the lifting mechanism 25 to raise or lower the frame 13, the operator can easily insert the fork into the wrist rest through-hole 15 and secure the fork to the frame 13 by operating the lifting mechanism 25 and the tilting mechanism 50.

[0096] like Figure 1 As shown, the first wheel assembly trolley 30A and the second wheel assembly trolley 30B are movable relative to the central assembly platform 20. Therefore, the first wheel assembly 19A and the second wheel assembly 19B can be assembled at other locations and then transported to the central assembly platform 20 using the first wheel assembly trolley 30A and the second wheel assembly 19B for assembly with the frame 13. The first wheel assembly trolley 30A and the second wheel assembly trolley 30B may each include a base plate 37, one or more rollers 38 disposed below the base plate 37, and a handle 39 connecting to the base plate 37. In some embodiments, the central assembly platform 20 may also be in the form of a trolley, and the central assembly platform 20 may include one or more rollers 28 disposed below the base 23 and a handle connecting to the base 23 (e.g., ...). Figure 2 Handle 29 shown.

[0097] like Figure 1 As shown, in some embodiments, the first wheel assembly trolley 30A and the second wheel assembly trolley 30B each further include a pivot device 31, a mounting base 35, and a side baffle 36. The mounting base 35 and the side baffle 36 are disposed on a base plate 37 and configured to abut against the bottom and side of the wheels of the first wheel assembly 19A or the second wheel assembly 19B, respectively. The mounting base 35 is rotatably connected to the base plate 37 via the pivot device 31 and includes a first portion 35P and a second portion 35Q extending inclined to the first portion 35P. With the above configuration, the second portion 35Q of the mounting base 35 can be tilted downwards to facilitate workers to place the first wheel assembly 19A or the second wheel assembly 19B onto or remove it from the first wheel assembly trolley 30A or the second wheel assembly 19B by rolling.

[0098] In some embodiments, the first wheel assembly trolley 30A and the second wheel assembly trolley 30B each include a limiting device (not shown) that can restrict the fixed seat 35 at a specific angle (e.g., the second part 35Q is higher than the first part 35P as shown in the figure), so that the first wheel assembly 19A or the second wheel assembly 19B can be stably stopped on the fixed seat 35.

[0099] Depending on practical needs, if the vehicle to be assembled has more than three wheels, the vehicle assembly system 12 may also include more than three wheel assembly trolleys, the structure of which may be similar to the first wheel assembly trolley 30A and the second wheel assembly trolley 30B.

[0100] Please refer to Figure 2 . Figure 2 For illustration Figure 1A schematic top view of the vehicle assembly system 12 is shown (some components omitted). As shown, the central assembly platform 20 further includes at least one first engagement element 21 and at least one second engagement element 22. The base 23 of the central assembly platform 20 has opposing first and second sides in the horizontal direction. The first engagement element 21 is disposed on the first side of the base 23, and the second engagement element 22 is disposed on the second side of the base 23. The first wheel assembly trolley 30A includes at least one third engagement element 33, which is disposed on the base plate 37 and protrudes from one edge of the base plate 37. The second wheel assembly trolley 30B includes at least one fourth engagement element 34, which is disposed on the base plate 37 and protrudes from one edge of the base plate 37. The third engagement element 33 and the fourth engagement element 34 are respectively configured to detachably connect the first engagement element 21 and the second engagement element 22 of the central assembly platform 20. The connecting elements have an alignment effect, so that when the central assembly platform 20, the first wheel assembly trolley 30A and the second wheel assembly trolley 30B are combined, the first wheel assembly 19A and the second wheel assembly 19B are positioned in a position that facilitates assembly with the frame 13.

[0101] like Figure 2 As shown, in some embodiments, one of the first engaging element 21 and the third engaging element 33 includes a first protrusion, and the other includes a first groove for receiving the first protrusion; similarly, one of the second engaging element 22 and the fourth engaging element 34 includes a second protrusion, and the other includes a second groove for receiving the second protrusion. In some embodiments, at least one side of the protrusion is beveled, and the inner wall of the groove has a corresponding bevel. In other embodiments, the first engaging element 21 and the third engaging element 33 may be a pair of interlocking hooks, and the second engaging element 22 and the fourth engaging element 34 may also be a pair of interlocking hooks.

[0102] Please refer to Figure 3 . Figure 3 For illustration Figure 1 The figure shows a schematic side view of the central assembly platform 20 from another angle. As shown, in some embodiments, the lifting mechanism 25 of the central assembly platform 20 includes a lifting frame 26 and a hydraulic rod 27. The lifting frame 26 is connected between the tilting mechanism 50 and the base 23. The hydraulic rod 27 is connected to the lifting frame 26 and configured to drive the lifting frame 26 to retract or extend, thereby changing the distance between the tilting mechanism 50 and the base 23. In some embodiments, the lifting frame 26 may include a plurality of staggered and pivotally connected rods. In some embodiments, the central assembly platform 20 also includes an operating box 24 disposed on the base 23, through which an operator can operate or set the lifting mechanism 25.

[0103] Please refer to Figure 4 . Figure 4 For illustration Figure 1 The diagram shows a detailed structure of the tilting mechanism 50 of the central assembly platform 20. As shown, in some embodiments, the tilting mechanism 50 includes a pivot device 51, a base 52, a fixing component 70, at least one guide rail 53, at least one slider 54, and a support column 55. The base 52 can be connected to the aforementioned lifting frame 26. The fixing component 70 is rotatably mounted above the base 52 via the pivot device 51 and configured to fix the aforementioned vehicle frame 13. The guide rail 53 is mounted on the base 52, the slider 54 is slidably mounted on the guide rail 53, and the opposite ends of the support column 55 are rotatably connected to the fixing component 70 and the slider 54, respectively. With the above configuration, the fixing component 70 can be tilted relative to the base 52 to a suitable angle.

[0104] like Figure 4 As shown, in some embodiments, the tilting mechanism 50 further includes one or more anti-collision blocks 56, which are disposed on the side of the base 52 facing the fixing component 70 or on the side of the fixing component 70 facing the base 52. The anti-collision blocks 56 prevent the fixing component 70 from impacting parts below it.

[0105] like Figure 4 As shown, in some embodiments, the tilting mechanism 50 further includes a first latch 57 and a second latch 58, which are respectively disposed on the fixing component 70 and the base 52 and can be engaged with each other to lock the fixing component 70 in the folded position when the vehicle assembly system 12 is not in use.

[0106] like Figure 4 As shown, in some embodiments, the tilting mechanism 50 further includes a locking device 60 disposed beside the guide rail 53 and configured to lock the slider 54 (so that the slider 54 is fixed), thereby locking the fixing component 70 at a specific tilting angle.

[0107] like Figure 4As shown, in some embodiments, the tilting mechanism 50 further includes a safety support column 67, which is mounted on the base 52 and configured to abut against the fixing component 70 to prevent the fixing component 70 from suddenly falling due to workers accidentally unlocking the locking device 60 (e.g., accidentally pressing the press handle 61 described below). In some embodiments, the safety support column 67 includes a column body 68 and a seat body 69, with the seat body 69 fixedly mounted on the base 52 and the column body 68 rotatably mounted on the seat body 69. When the safety support column 67 is not needed (e.g., during non-working hours), the column body 68 can be folded up by rotating it to the side of the seat body 69. During assembly operations, the fixing component 70 can be first lifted and locked at a specific tilt angle using the locking device 60, and then the column body 68 can be straightened so that it protrudes upward and abuts against the fixing component 70, ensuring the safety of the workers.

[0108] Please refer to Figure 5 . Figure 5 For illustration Figure 4 The enlarged view of the tilting mechanism 50 shown is located at the point marked by the dashed box. As shown, the locking device 60 includes a seat 65 disposed at the end of the guide rail 53 and a pressing handle 61. The seat 65 is fixedly mounted on the base 52, and the pressing handle 61 is pivotally connected to the seat 65 and configured to rotate between a first position and a second position. In the first position, the pressing handle 61 interferes with the slider 54, fixing the slider 54 in place. In the second position, the pressing handle 61 disengages from the slider 54, allowing the slider 54 to slide along the guide rail 53. In some embodiments, the pressing handle 61 includes a latch 62 configured to engage with the slider 54.

[0109] like Figure 5 As shown, in some embodiments, the locking device 60 further includes an elastic element 64 (e.g., a coil spring) connected to the press handle 61 and the base 52, and configured to provide a torque driving the press handle 61 to rotate toward a first position (e.g., the position of the press handle 61 shown in the figure, where the press handle 61 interferes with the slider 54). Additionally, the front end of the latch 62 of the press handle 61 has a bevel 63. Thus, when the slider 54 slides to the end of the guide rail 53, the slider 54 interferes with the bevel 63 of the latch 62, causing the latch 62 to lift. Subsequently, the restoring force of the elastic element 64 drives the latch 62 to descend and engage with the slider 54. In other words, with the above structural configuration, the function of automatically locking the slider 54 when it slides to the end of the guide rail 53 can be achieved.

[0110] like Figure 5As shown, in some embodiments, the slider 54 has an inclined surface 59, which corresponds to the inclined surface 63 of the hook 62 and has the same inclination direction. Therefore, when the slider 54 slides to the end of the guide rail 53, the inclined surface 63 of the hook 62 can slide along the inclined surface 59 of the slider 54, allowing the hook 62 to be lifted more smoothly.

[0111] Please refer to the above as well. Figure 6 . Figure 6 For illustration Figure 4 A schematic top view of the guide rail 53, slider 54, and limiting device 80 of the tilting mechanism 50 shown. Figure 6 and Figure 7 As shown, in some embodiments, the tilting mechanism 50 further includes a limiting device 80, which is disposed at the end of the guide rail 53 and has the function of preventing the slider 54 from disengaging from the guide rail 53. In some embodiments, the limiting device 80 includes a seat 85 and a bolt 83. The seat 85 is fixedly disposed on the base 52, and the bolt 83 passes through the seat 85, with the end of the bolt 83 facing the slider 54 for the slider 54 to abut against. The bolt 83 can be rotated to change its length protruding from the seat 85, thereby controlling the maximum tilt angle of the aforementioned fixing assembly 70. In some embodiments, the limiting device 80 includes a buffer 81, which passes through the seat 85 and includes a telescopic rod 82 located on the side of the buffer 81 facing the slider 54. The telescopic rod 82 is configured for the slider 54 to abut against, and when pushed by the slider 54, the telescopic rod 82 retracts inward and provides resistance to the slider 54. In some embodiments, the buffer 81 may be a hydraulic damper.

[0112] Please refer to Figure 7 . Figure 7 For illustration Figure 4 The figure shows a perspective view of the fixing assembly 70 of the tilting mechanism 50 from another angle. As shown, in some embodiments, the fixing assembly 70 includes a carrier plate 71, at least one positioning device 77, and at least one clamping device 75. The carrier plate 71 is connectable to the aforementioned pivot assembly 51 and has a frame placement space 73. The positioning device 77 and the clamping device 75 are disposed on the carrier plate 71 and located on at least one side of the frame placement space 73. The positioning device 77 is configured to engage with the alignment hole (not shown) of the frame 13 to confirm that the frame 13 is correctly positioned, while the clamping device 75 is configured to press and fix the frame 13 onto the carrier plate 71. In some embodiments, a positioning device 77 and a pair of clamping devices 75 are disposed on each opposite side of the frame placement space 73.

[0113] like Figure 7As shown, in some embodiments, the positioning device 77 includes a handlebar 72, a translation mechanism 78, and a positioning head 79. The positioning head 79 is configured to insert into an alignment hole in the frame 13. The translation mechanism 78 is connected to the positioning head 79 and configured to drive the positioning head 79 to extend or retract toward the frame placement space 73. The translation mechanism 78 is linked to the handlebar 72, and the operator can control the extension or retraction of the positioning head 79 by pushing or pulling the handlebar 72.

[0114] like Figure 7 As shown, in some embodiments, the clamping device 75 includes a handle 72, a rotating mechanism 74, and a pressing block 76. The pressing block 76 is configured to press against the frame 13. The rotating mechanism 74 is connected to the pressing block 76 and configured to drive the pressing block 76 to press down or lift. The rotating mechanism 74 is linked to the handle 72, and the operator can control the pressing block 76 to press down or lift by pushing or pulling the handle 72.

[0115] Please refer to Figure 8 . Figure 8 A schematic top view is provided to illustrate a fifth connecting element 95 and a sixth connecting element 96 according to another embodiment of this disclosure. The fifth connecting element 95 is configured to detachably connect to the sixth connecting element 96. The fifth connecting element 95 and the sixth connecting element 96 may respectively serve as the aforementioned first connecting element 21 and third connecting element 33, third connecting element 33 and first connecting element 21, second connecting element 22 and fourth connecting element 34, or fourth connecting element 34 and second connecting element 22.

[0116] like Figure 8 As shown, the sixth engaging element 96 includes a circular protrusion 97. The fifth engaging element 95 includes a seat 93, a first arcuate element 91, a second arcuate element 92, and two elastic elements 94 (e.g., coil springs). The first arcuate element 91 and the second arcuate element 92 are arranged side by side and together form a receiving groove configured to receive the circular protrusion 97 of the sixth engaging element 96. One end of each of the two elastic elements 94 is connected to the seat 93, and the other end is connected to the first arcuate element 91 and the second arcuate element 92, respectively, allowing the first arcuate element 91 and the second arcuate element 92 to move in a restricted manner on the seat 93. In some embodiments, the seat 93 has a groove 90 that provides space for the first arcuate element 91 and the second arcuate element 92 to retract when the elastic elements 94 are compressed, that is, the first arcuate element 91 and the second arcuate element 92 can partially enter the groove 90.

[0117] In summary, this disclosure provides a vehicle assembly system that assists assemblers in assembling bicycles, electric bicycles, electric motorcycles, and other similar vehicles.
