Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described。Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this。
As shown in Figures 1 to 3, folding mechanism for vehicle frame includes: connector 9a, the first gear 9b, the second gear 9c and gear lock stop member。
Connector 9a includes and the fixing forelimb being connected of vertical tube of front fork 3 and the rotating shaft being rotationally connected with girder 1, and forelimb is vertical with rotating shaft to be connected, and adopts steel one forging molding for improving the intensity of connector 9a, forelimb and rotating shaft。
First gear 9b is fixed in rotating shaft, and the second gear 9c is sincere, and first gear 9b and the second gear 9c is meshed with on crossbeam 2, and gear lock assembly is used for stoping the first gear 9b and the second gear 9c to relatively rotate。
Gear lock assembly includes lock pin 9d, pull bar 9e, stage clip 9f, drags axle 9g and is fixed on lock pin installing plate 9r with the fixing keeper 9h, lock pin 9d being connected of crossbeam 2, and stage clip 9f is supported between lock pin installing plate 9r and keeper 9h。Pull bar 9e one end is fixing with lock pin installing plate 9r to be connected, other end order runs through stage clip 9f, keeper 9h and is connected with dragging axle 9g, connector 9a is additionally provided with positioning boss 9i, offering on positioning boss 9i for the lock pin 9d dowel hole 9j inserted, the sidewall of the second gear 9c is further fixed on lock pin guide pipe 9q。When folded bicycle is in open mode, lock pin 9d inserts in dowel hole 9j through lock pin guide pipe 9q, extrudes through stage clip 9f, it is ensured that lock pin 9d will not deviate from from dowel hole 9j。
Under normal circumstances, saddle is installed on crossbeam 2, pulls dragging axle 9g for being more convenient for, and is additionally provided with dragging handle 9k at the rear portion of crossbeam 2。As shown in Figure 4, drag handle 9k to be in transmission connection with dragging axle 9g by pull bar 9e。Crossbeam 2 is offered respectively: for the dragging axle 9g stopper slot slided before and after dragging axle 9g, for dragging the handle limited groove slided before and after handle 9k。Neat and artistic for ensureing folded bicycle profile, draw bar 9p is located in crossbeam 2。The front end of draw bar 9p is connected with dragging axle 9g by dragging axle 9g stopper slot, and rear end is connected with dragging handle 9k by handle limited groove。
When folded bicycle needs folding, firmly pull dragging handle 9k backward, lock pin 9d is made to deviate from from dowel hole 9j, press down on crossbeam 2, first gear 9b and the second gear 9c relatively rotates, realize the folding of girder 1, crossbeam 2 and vertical tube of front fork 3, when opening, make lock pin 9d reinsert in dowel hole 9j。The present invention is applicable to electric motor bicycle with folding, folding bicycle, has the advantage that folding convenient is quick, time saving and energy saving, adopts gears rotational structure simultaneously, and weight capacity is strong, have longer service life, not easily occur skidding, safety is higher。
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention。
