DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0023] The present utility model provides a motorcycle integrated load-bearing frame as shown in Figures 1 - 5 Figure, which includes a main beam 1, and also includes a rear tail assembly and a fixing assembly 4;

[0024] Specifically, the rear tail assembly includes auxiliary tail beams 2 symmetrically arranged on the outer side of one end of the main beam 1. A tail main beam 3 is arranged on the side of the auxiliary tail beam 2. A front panel 101 is arranged at the other end of the main beam 1. A mudguard 104 is arranged on the side of the front panel 101 away from the main beam 1;

[0025] It should be noted that the two auxiliary tail beams 2 overlap with the outer side of the main beam 1. The overlapping parts of the tail main beam 3, the auxiliary tail beam 2 and the main beam 1 are fixed by rivets. A sealing part is arranged at the bottom of the main beam 1 for closing the bottom of the main beam 1;

[0026] Specifically, the sealing part includes a beam bottom plate 102 arranged at the bottom of the main beam 1. A bottom support 103 is arranged at the bottom of the main beam 1 and below the beam bottom plate 102. One end of the bottom support 103 is fixedly connected to the side of the tail main beam 3. A lamp slot 1013 is opened on the side of the front panel 101 away from the main beam 1 for placing lighting lamps;

[0027] It should be noted that the beam bottom plate 102 is fixedly connected to the main beam 1 by riveting, and the bottom support 103 is fixedly connected to the outer side of the bottom of the main beam 1 by riveting;

[0028] Specifically, the fixing assembly 4 is used for fixing the mudguard 104 and the front panel 101. The fixing assembly 4 includes connecting convex blocks 401 symmetrically arranged on the inner side of the mudguard 104. A fixing bolt 402 for inserting and fixing the mudguard 104 and the front panel 101 is inserted through the side of the connecting convex block 401. A loosening prevention part is arranged at the insertion part of the fixing bolt 402 and the connecting convex block 401;

[0029] It should be noted that the connecting convex blocks 401 are fixedly connected to the inner side of the mudguard 104 by welding. The first fixing groove 1011 and the second fixing groove 1012 for inserting the fixing bolt 402 are symmetrically arranged on the side of the front panel 101 away from the main beam 1. Nuts 406 for locking the fixing bolt 402 are arranged on the inner walls of the first fixing groove 1011 and the second fixing groove 1012;

[0030] Specifically, the nut 406 is fixedly welded to the inner walls of the first fixing groove 1011 and the second fixing groove 1012. The connecting lug 401 is provided with a protrusion that can penetrate the first fixing groove 1011 and the second fixing groove 1012.

[0031] Specifically, the anti-loosening part includes a sleeve 403 sleeved on the outer side of the fixing bolt 402. A pressure ring 405 and a compression spring 404 are sleeved on the outer side of the fixing bolt 402 and located in the inner cavity of the sleeve 403. The pressure ring 405 is arranged at one end of the compression spring 404 away from the nut 406.

[0032] It should be noted that a movable groove is formed on the side of the connecting lug 401 for the sleeve 403 to penetrate and be fixed. The middle part of the pressure ring 405 is fixedly welded to the outer side of the fixing bolt 402. As the fixing bolt 402 rotates in the middle of the nut 406, the pressure ring 405 is driven to squeeze the compression spring 404, so that the compression spring 404 gives a thrust to the fixing bolt 402, making the threaded engagement between the fixing bolt 402 and the nut 406 in close contact, thereby preventing the fixing bolt 402 from loosening due to vibration.

[0033] Specifically, an isolation ring 4021 is arranged on the outer side of the fixing bolt 402 and on the side of the connecting lug 401 to prevent water from flowing into the movable groove.

[0034] During actual use, a rear tail assembly is arranged at one end of the main beam 1. The auxiliary tail beam 2 is fixed to the main beam 1, and the main tail beam 3 is fixed to the auxiliary tail beam 2. A front panel 101 and a fender 104 are arranged at the other end of the main beam 1. The fender 104 and the front panel 101 are fixed by a fixing assembly 4. The main beam 1, the rear tail assembly, the front panel 101 and the sealing part are all formed by stamping high-strength steel plates and then directly spliced to form the whole vehicle frame. Compared with the tube beam vehicle frame, after the tube beam vehicle frame is welded, it is necessary to splice the outer shell on the outside of the tube beam. In this design, the components are directly formed by stamping and then riveted and fixed to form the vehicle frame, eliminating the time-consuming outer shell splicing process of the tube beam vehicle frame.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
