Description
Technical Field
The utility model relates to an electric bicycle accessory technical field specifically is a mounting structure for electric bicycle's unthreaded flywheel.
Background
The electric bicycle is provided with a chain and a flywheel according to the requirements of relevant national standards and requirements so as to meet the requirement of manual riding. But because the existing flywheels are all in threaded fastening structures, the installation speed is slow, and the efficiency is low. Meanwhile, the condition that the flywheel loosens and falls off due to the counterforce generated by sliding of the chain and the flywheel outer gear ring also exists, and the chain falls off once the flywheel falls off, so that the vicious events that the rear wheel is blocked, the motor lead-out wire is damaged and the like to cause abnormal riding and even casualties occur.
The existing solutions, such as using a special tool, screwing a thread glue and the like, can not solve the problem of low installation efficiency, and bring a certain degree of labor for enterprises. Meanwhile, the problem of flywheel falling is not really solved. Therefore, it is necessary to design a mounting structure of a screwless flywheel for an electric bicycle.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides a mounting structure for electric bicycle's unthreaded flywheel, this mounting structure, novel structure thinks about ingeniously, has got rid of original flywheel and motor end cover screw thread processing link, has reduced the parts machining cost, has reduced the installation degree of difficulty simultaneously, improves assembly efficiency to avoid the flywheel problem of droing to produce, promoted overall economic benefits.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an installation structure for electric bicycle's unthreaded flywheel, is including only changeing the motor end cover, only changeing the top center department of motor end cover and being provided with the axle bed, cup joint on the axle bed and be fixed with unthreaded flywheel, unthreaded flywheel bottom recess joint all around is fixed on axle bed boss all around only changeing, the draw-in groove has been seted up on the top of axle bed, the inside joint of draw-in groove is fixed with the jump ring with the contact of unthreaded flywheel.
Preferably, the rotation stopping bosses are distributed around the bottom of the shaft seat in a cross shape, and the grooves are distributed around the bottom of the unthreaded flywheel in a cross shape.
Preferably, the rotation stopping motor end cover, the shaft seat and the rotation stopping boss are integrally formed by a die.
The utility model has the advantages that:
when the unthreaded flywheel is installed, the unthreaded flywheel is sleeved on the shaft seat, the groove is aligned to the rotation stopping boss and pushed in, the clamp spring is clamped into the clamping groove, the unthreaded flywheel is prevented from withdrawing, the original thread machining links of the flywheel and the motor end cover are removed, the part machining cost is reduced, the installation difficulty is reduced, the assembly efficiency is improved, the problem that the flywheel drops is avoided, and the overall economic benefit is improved.
