Embodiment

It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.

As shown in Fig. 1, Fig. 4-6, it discloses chain stay after a kind of wheel driving force car, and the connection of rear chain stay and trim Structure.It includes hind axle 1, rear chain stay 2 and trim 3, and rear chain stay 2 has two yokes 4 being oppositely arranged, two yokes 4 Leading section be connected as a single entity, the rearward end of each yoke 4 offers the breach 5 for grafting hind axle 1, and trim 3 is positioned at fork The rearward end of arm 4, mutually fixed by snapping or thread connecting mode between the front portion of trim 3 and yoke 4, the rear end of yoke 4 Face offers locating slot 6, and the rear portion of trim 3 has alignment pin 7, and alignment pin 7 is plugged in locating slot 6.To ensure connection The rear chain stay 2 of two-wheel power vehicle is balanced typically in forked, there is two yokes 4, one end of the rear opening of chain stay 2 and the phase of hind axle 1 It is connected, the both ends of hind axle 1 are plugged in the breach 5 opened up on two yokes 4 respectively, and then the yoke 4 of the other end two of chain stay 2 is solid It is connected as a single entity and is fixedly connected with again with vehicle frame, the stable relation so formed between trailing wheel and main body frame, trim 3 is typically directly with after Chain stay 2 is fixedly connected with, and the connecting portion of rear chain stay 2 and hind axle 1 is carried out into covering protection, while lift aesthetics.Opened up on yoke 4 The end grafting that is used for hind axle 1 of breach 5 coordinate, trim 3 is arranged on to the rearward end of yoke 4, connection can be blocked Part, and recover the globality of the moulding of yoke 4, the front portion of trim 3 and yoke 4 are mutually fixed by snapping or be spirally connected, realization Fastening to trim 3 is strengthened, and by setting what the alignment pin 7 at the rear portion of trim 3 was plugged in that the rear end face of yoke 4 opens up to determine In the groove 6 of position, positioning is provided for the assembling of trim 3, and is realized to the further positioning fastening of trim 3, is improved The connective stability of chain stay 2 and trim 3 afterwards.

As Figure 1-4, trim 3 covers breach 5, and trim 3 includes top cover 31 and rear end cap 32, and top cover 31 is anterior Mutually fixed with yoke 4, alignment pin 7 is fixed on rear end cap 32, and the rear end at the edge and top cover 31 of rear end cap 32 is fixedly connected with, rear end The rear end face of lid 32 and yoke 4 leans.Hind axle 1 is plugged in the breach 5 on yoke 4, and trim 3 covers breach 5 Whole breach 5 and connector can be subjected to covering protection, by setting top cover 31, by the hind axle 1 in the region of breach 5 and protection The connectors such as piece cover, and set rear end cap 32 to cover the rear end face of yoke 4, will be fixed so as to realize the effect of multi-angle protection Position pin 7 is fixed on rear end cap 32, while the front portion of top cover 31 is also mutually fixed between yoke 4, so from two different directions Spacing and fastening is carried out to trim 3, improves the connective stability of rear chain stay 2 and trim 3.For further, alignment pin 7 Bearing of trend it is consistent with the length direction of yoke 4, the length of closure and yoke 4 between the front portion of top cover 31 and yoke 4 Direction is vertical.Alignment pin 7 makes the possibility that trim 3 is only axially moved along alignment pin 7 after coordinating with locating slot 6, fixed when setting During the closure extended perpendicularly between top cover 31 and yoke 4 of position pin 7, snapping or screw thread connect between top cover 31 and yoke 4 Connect, farthest limit axial movement of the trim 3 along alignment pin 7, so as to the connection of chain stay 2 and trim 3 after being lifted Stability.Preferably, the front portion of top cover 31 is provided with least one mounting hole 31a, yoke 4 is provided with to match with mounting hole 31a The screwed hole 43 of conjunction.By the fixation that is spirally connected typically between trim 3 and rear chain stay 2, at least one peace is set in the front portion of top cover 31 Hole 31a is filled, is coordinated by the screwed hole 43 in fastening screw and yoke 4 and fixed, the engagement thread formed between top cover 31 and yoke 4 It is connected, it cooperatively forms more stable attachment structure with the structure of alignment pin 7 on rear end cap 32.The bottom of top cover 31 is consolidated Be connected with screw column 35, screw column 35 is tubular structure, the upper end open of screw column 35 connected with mounting hole 31a and with mounting hole 31a It is coaxially set, the lower ending opening of screw column 35 and the face of screwed hole 43.Fastening screw loads from mounting hole 31a, then passes through spiral shell Silk post 35, which screws in, to be arranged in the screwed hole 43 on yoke 4, by setting the cored screw post arranged with mounting hole 31a coaxial lines 35, guiding is provided with docking for screwed hole 43 for fastening screw, improves efficiency of assembling, while screw column 35 can also be fastening spiral shell Silk is provided and is effectively protected, and improves the stability of structure, can also be on top cover 31 and yoke 4 respectively as other schemes Clamping part is set, and formation is fastened, and it is all more convenient to dismount and safeguard.

As shown in Fig. 1, Fig. 4-6, yoke 4 includes outer cover 41 and reinforcing plate 42, and reinforcing plate 42 is located at the inner side of outer cover 41, added The rearward end jag of strong plate 42 forms an interdigital 42a an interdigital 42b, rearward end jag of outer cover 41 with and forms interdigital two 41a interdigital two 41b with, upper interdigital two the 41a interdigital two 41b outwardly convexs with are in bending, upper interdigital two 41a top edge Be fixedly connected with lower edge with a upper interdigital 42a and form the locating slot 6 of one between the two, under interdigital two 41b top edge An interdigital 42b is fixedly connected with and forms another locating slot 6 between the two with lower edge, and alignment pin 7 has two, each Alignment pin 7 is corresponding to be plugged in a locating slot 6.Reinforcing plate 42 improves the bulk strength of yoke 4, added located at the inner side of outer cover 41 The strong rear end of plate 42 and the rear end of outer cover 41 difference jag, the prong of jag is the breach 5 on yoke 4, upper interdigital two 41a and lower fork It is in bending to refer to two 41b to be both designed as outwardly convex, so its with the upper interdigital 42a in reinforcing plate 42 and under an interdigital 42b Meeting two locating slots 6 of self-assembling formation are respectively fixedly connected, set two alignment pins 7 to strengthen positioning and spacing effect, and ensure and exist One alignment pin 7 still is able to positioning and spacing effect in the case of failing, and the connection of chain stay 2 and trim 3 is steady after lifting It is qualitative.

As shown in Figure 1, Figure 2, Figure 6 shows, the two bottom sides of top cover 31 are respectively fixedly connected the guiding wing plate 1 being oppositely arranged and led To wing plate 2 34, upper interdigital two 41a downside is the inclined 41c of spigot surface one, under interdigital two 41b upper side to be inclined The 41d of spigot surface two, guiding wing plate 1 can be slipped into along the 41c of spigot surface one and both lean, and being oriented to wing plate 2 34 can Slipped into along the 41d of spigot surface two and both lean.Alignment pin 7 needs to match with locating slot 6 in assembling process, by pushing up The bottom of the lower end of lid 31, which is set, to be oriented to wing plate 1 and is oriented to wing plate 2 34, in assembling process, is oriented to wing plate 1 and is oriented to Wing plate 2 34 can slip into along the 41c of spigot surface one and the 41d of spigot surface two respectively and both lean, and thus define alignment pin 7 bob, assembling is more convenient, improves the efficiency of assembling of trim 3.

It is only preferred embodiment of the present utility model in summary, is not used for limiting implementation model of the present utility model Enclose.The equivalent changes and modifications that i.e. all contents according to present utility model application the scope of the claims are made, all should be of the present utility model Technology category.
