Specific embodiment

With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the simple electric bicycle front fork structure of the present embodiment, including standpipe 1, the bottom of standpipe 1 is equipped with lower linking plate 3 by limiting steering block 2, and the both ends of lower linking plate 3 are symmetrically installed with downwards front fork branch Bar between two front fork struts and is located at the bottom of lower linking plate 3 and is provided with mud plate bracket 6；The structure of single front fork strut are as follows: packet Aluminum barrel 8 is included, stepped hole is provided in the middle part of aluminum barrel 8, stepped hole is interior inserted with accurate handle pipe 5, and the top of accurate handle pipe 5 is equipped with silently 4, it silently 4 is connect with lower linking plate 3, passes through oil sealing 11 and dustproof cover 10 between 8 top inner wall face of aluminum barrel and accurate 5 outside wall surface of handle pipe Connection, for accurate 5 bottom of handle pipe inside aluminum barrel 8 inserted with piston rod 18, the lower part of piston rod 18 is fixed by positioning seat 19 Position, bottom are locked by seabed screw 20, and 18 head outer ring of piston rod is cooperated by the inner wall of piston ring 12 and accurate handle pipe 5 and connected It connects, 18 top outer ring of piston rod is also equipped with ring gear 16, and the outer ring of ring gear 16 is equipped with valve seat 14, valve seat 14 and 16 top of ring gear Between saddle gasket 15 is installed, saddle gasket 15 is nested with outside piston rod 18, and inner ring 17, valve are also equipped with below valve seat 14 Damping spring 13 is installed, the inner cavity of the accurate handle pipe 5 at 18 top of piston rod is equipped between 14 top of seat and 18 head of piston rod Buffer spring 9；Lock screw 7 is also equipped at the inner wall of aluminum barrel 8.

The structure in the arc-shaped of lower linking plate 3.

Silently 4 it is tightly connected by sealing ring 21 and accurate handle pipe 5.

The utility model is suitable for various simple electric bicycles.

The utility model, which has filled up simple electric bicycle in the market, does not have the blank of hydraulic damper.
