DETAILED DESCRIPTION

[0025] The embodiments of the present application are described below by way of specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the disclosure of the specification. The present application can also be implemented or applied in other different embodiments, and the details in the specification can be modified or changed in various ways without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0026] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and the drawings only show the components related to the present application, not the number, shape and size of the components when actually implemented. The shape, number and ratio of each component can be changed arbitrarily when actually implemented, and the layout pattern of the components can also be more complex.

[0027] The specific embodiments of the present application are further described below with reference to the accompanying drawings.

[0028] Embodiment:

[0029] The embodiment of the present application discloses a deformation-resistant frame structure convenient to assemble, which, as understood with reference to Figure 1 , comprises a faucet shaft sleeve 1, two frame bodies 2, a rear seat support 3 and a rear fork 4.

[0030] The frame body 2 is fixed on both sides of the rear seat bracket 3. The front ends of the two frame bodies 2 are fixed on the handlebar bushing 1, and the rear horizontal fork 4 is fixed to the rear of the two frame bodies 2.

[0031] Combination Figure 2 , Figure 3 and Figure 4 The faucet bushing 1 has a first mounting base 11 and a second mounting base 12, with the first mounting base 11 positioned above the second mounting base 12. Both the first and second mounting bases have a first mating groove 13, which contains at least one elongated positioning groove 111 and at least one circular positioning groove 112. Coarse bolt holes 14 are located within the elongated and circular positioning grooves 111 and 112, respectively. Fine bolt holes 15 are also provided on the first mating groove 13. The diameter of the coarse bolt hole 14 is larger than that of the fine bolt hole 15. Therefore, when a bolt passes through the coarse bolt hole 14, due to the larger hole diameter, and assuming the bolt is of the same specification (meaning a larger hole diameter relative to the pre-reserved clearance for bolt installation), the bolt can easily pass through the coarse bolt hole 14. These bolt holes can be plain or threaded later, but alignment is necessary during the initial assembly. Therefore, bolts are used for initial positioning and to determine and fix the relative positions. At this point, the position can be finely adjusted through the coarse bolt hole 14.

[0032] Conversely, the frame body 2 needs to be assembled onto the upper steering wheel bushing 1. The front inner side of the frame body 2 is provided with a first assembly block 21 that mates with the first assembly groove 13. The first assembly block 21 is provided with a long waist positioning post 211 that matches the long waist positioning groove 111 and a circular positioning post 22 that matches the circular positioning groove 112. The long waist positioning post 211 and the circular positioning post 22 are provided with coarse bolt holes 14, and the first assembly block 21 is provided with fine bolt holes 15.

[0033] During assembly, the first assembly block 21 is first embedded into the first assembly groove 13, and initial positioning is achieved using the long waist positioning post 211 and the long waist positioning groove 111. At this point, the long waist positioning groove 111 also provides support for the long waist positioning post 211, thus supporting the frame body 2. Then, bolts are inserted into the coarse bolt holes 14 at this location for further positioning, and fine-tuning is also possible. Next, using this bolt as a support position, assembly continues. The first mounting base 11 and the second mounting base 12 are respectively provided with protruding posts 16, which are inserted into the column grooves 23 on the inner side of the frame body 2. During continued assembly, the protruding posts 16 and column grooves 23 are continuously engaged and their positions adjusted. With the initial support and positioning, the installation of the more precisely fitted protruding posts 16 and column grooves 23 becomes very easy, allowing for easy alignment and subsequent bolt installation.

[0034] The gap between the first split groove 13 and the first split block 21 is L1, the gap between the long waist positioning groove 111 and the long waist positioning column 211 is L2, and the gap between the convex column 16 and the column groove 23 is L3, wherein L1 is greater than L2, and L2 is greater than L3. The purpose of the gap is to adjust the split position so as not to be stuck, and to improve the convenience of installation while being more accurate. After the convex column 16 and the column groove 23 are matched, the bolt and nut can be installed for fixation. In addition, the light hole can be tapped. It can be installed with reliable bolts to complete assembly.

[0035] Since the structure of the frame body 2 is only fixed at the front end, it is still not stable enough, so the middle part of the frame body 2 is provided with a second positioning groove 24, and the rear seat support 3 is provided with a second positioning column 31, and the first positioning groove and the second positioning column 31 are split and fixed by bolts. As can be seen, this way further improves the stability of the structure, and the frame body 2 is not easy to collapse. The second positioning groove 24 and the second positioning column 31 are arranged in multiple arc shapes, which can effectively disperse stress.

[0036] As can be seen from the above, based on the faucet shaft sleeve 1 having a first mounting seat 11 and a second mounting seat 12, when the front end of the frame body 2 is matched, it needs to be spliced, first, the first split block 21 and the first split groove 13 are split, at this time, the long waist positioning column 211 is also inserted into the long waist positioning groove 111, further correcting the position, on the other hand, it also combines the coarse bolt hole 14 and the fine bolt hole 15 to assemble and fix, thereby improving the assembly efficiency, avoiding the misalignment of the bolt hole, and greatly improving the assembly efficiency. Further combined with the cooperation of the convex column 16 and the column groove 23 to improve the structure assembly strength and improve the deformation resistance, at the same time, due to the different matching gaps, the position can be fine-tuned, thereby facilitating assembly and fixing of the bolt. After the front end of the frame body 2 is fixed, the middle part also needs to be fixed, and the middle part is also assembled by the split mode of the second positioning groove 24 and the second positioning column 31, and the fixed part adopts multiple arc shapes, thereby greatly improving the deformation resistance.

[0037] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, any equivalent changes made to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
