[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] This application provides a motorcycle comprising a frame, which is the core component of the motorcycle used to mount components such as the engine, handlebars, and rear swingarm, and to ensure overall structural stability. The frame features a detachable structure, allowing for easy installation and removal of the engine from one end while controlling the other. Furthermore, fasteners can be replaced when mileage is excessive or road conditions are complex, reducing frame fatigue and wear.

[0029] The following detailed explanation uses a motorcycle frame as an example.

[0030] like Figure 1 As shown, this application embodiment provides a frame including a steering riser 10, a side tube 20, a support frame 30, and a rear swingarm connector 40. The steering riser 10 is used to mount the motorcycle's handlebars, and the rear swingarm connector 40 is used to mount the motorcycle's rear swingarm. The side tube 20, the support frame 30, and the rear swingarm connector 40 form an engine mounting space. The engine is mounted within the mounting space and then fixed to the frame.

[0031] The steering riser 10 extends downwards to form a connecting pipe 50, which is integrally connected to the steering riser 10. The connecting pipe 50 and the steering riser 10 can be welded together. Two connecting pipes 50 are provided, forming an angle between them. Side tubes 20 are detachably connected to the ends of the two connecting pipes 50 via fasteners. A support frame 30 is detachably connected to the end of the side tube 20 away from the connecting pipes 50 via fasteners. The support frame 30 is fixedly connected to the rear swingarm link 40. The side tubes 20, support frame 30, and rear swingarm link 40 are connected to form a cradle-shaped or boat-shaped structure. By using detachable connections between the steering riser 10 and the side tubes 20, and between the side tubes 20 and the support frame 30, assembly and disassembly are facilitated. This also allows for easy engine removal and installation at one end of the frame while controlling one end. Furthermore, fasteners can be replaced when mileage is excessive or road conditions are complex, reducing frame fatigue wear.

[0032] like Figure 2 and Figure 3 As shown, specifically, the end of the connecting pipe 50 is provided with a first connecting end 51, and one end of the side pipe 20 is provided with a second connecting end 21. The second connecting end 21 and the first connecting end 51 can cooperate. For example, the first connecting end 51 can be inserted into the second connecting end 21 and detachably connected by fasteners, or the first connecting end 51 and the second connecting end 21 can be stacked on top of each other and detachably connected by fasteners. Correspondingly, the other end of the side pipe 20 is provided with a third connecting end 22, and the support frame 30 is provided with a fourth connecting end 31. The cooperation between the fourth connecting end 31 and the third connecting end 22 can be that the third connecting end 22 is inserted into the fourth connecting end 31 and locked by fasteners, or the third connecting end 22 and the fourth connecting end 31 can be stacked on top of each other and detachably connected by fasteners. It should be noted that the above-mentioned plug-in method and the overlapping method do not limit which end is the insertion end or the inserted end, or which end is at the top and which end is at the bottom of the overlap. By adopting the above method, a detachable connection can be achieved between the steering riser 10, the side tube 20 and the support frame 30, and the above components can be quickly disassembled and assembled in special circumstances.

[0033] The fasteners used in this application are screws, which provide good performance and long service life. Of course, in some embodiments, the fasteners can also be cable ties. However, considering the lifespan and strength of cable ties, screw fastening is a better option.

[0034] In this application, the connection between the steering riser 10, the side tube 20, and the support frame 30 is achieved by overlapping the ends and locking them with screws. Specifically, the first connecting end 51 is a first boss extending outward relative to the connecting tube 50, with the bottom surface of the first boss being a plane. The second connecting end 21 is a second boss extending outward relative to the side tube 20, with the top surface of the second boss being a plane. The bottom surface of the first boss and the top surface of the second boss are in contact. The precision of the frame can be controlled by machining the first and second bosses. Threaded holes 60 are provided on both the first and second bosses. The threaded holes 60 of the first and second bosses are aligned. Screws are inserted into the threaded holes 60 and pass through the first and second bosses in sequence to connect the first and second bosses together. Similarly, the third connecting end 22 is a third boss extending outward relative to the side tube 20, and the top surface of the third boss is flat. The fourth connecting end 31 is a fourth boss extending outward relative to the support frame 30, and the bottom surface of the fourth boss is flat. The top surface of the third boss and the bottom surface of the fourth boss are in contact. The precision of the frame can be controlled by forging and welding of the third boss and the fourth boss. Threaded holes 60 are provided on the third boss and the fourth boss. The threaded holes 60 of the third boss and the fourth boss are aligned. The screw is inserted into the threaded hole 60 and passes through the third boss and the fourth boss in sequence to connect the third boss and the fourth boss together.

[0035] like Figure 3 and Figure 4 As shown in this application, the end of the support frame 30 furthest from the side tube 20 is inserted and fixed to the rear horizontal fork connecting frame 40. Specifically, the end of the support frame 30 furthest from the side tube 20 is provided with a plug-in seat 32, and the rear horizontal fork connecting frame 40 is provided with a plug connector 41 adapted to the plug-in seat 32. The plug connector 41 is provided with a socket, and the plug-in seat 32 is inserted into the socket and fixed in the plug connector 41. The plug-in seat 32 and the socket are clearance fit to ensure stable connection between the two. In some embodiments, the plug-in seat 32 can also be welded and fixed after being inserted into the socket.

[0036] like Figure 1 As shown, to facilitate engine installation, first lugs 70 are provided on each of the two side tubes 20. The two first lugs 70 are at the same horizontal height. The support frame 30 includes a horizontal tube 33, which connects to two fourth connecting ends 31. The horizontal tube 33 spans the two side tubes 20. Two second lugs 80 are provided at intervals on the horizontal tube 33. The two first lugs 70 and the two second lugs 80 are used to connect and fix with the corresponding mounting parts on the engine so that the engine is installed stably on the frame.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
