505, and then front vehicle wheel is installed on electric bicycle front fork 100.The area of section of installing plate 504 is along the bottom of sleeve 502
Direction toward top is gradually reduced, and can strengthen the support force of connecting plate, prevents connecting plate from deforming during long-term use.
In addition, having pilot hole 506 in piston 501, lead column 503 stretches into pilot hole 506.Being oriented to can be in pilot hole
Slide in 506.The first damping spring 507 is arranged with outside lead column 503, one end and the sleeve 502 of the first damping spring 507 connect
Connect, the other end offsets with the end of piston 501.
Additionally, the second damping spring 508 is provided with pilot hole 506, one end and the piston 501 of the second damping spring 508
Connection, the other end is provided with the sliding shoe 509 rounded for propping up the section of lead column 503.Sliding shoe 509 and piston 501
Medial wall be slidably connected.Specifically, sliding shoe 509 coordinates with the gap of pilot hole 506.Sliding shoe 509 is with lead column 503 most
Stroke of the big distance less than piston 501.
During riding, on prevailing roadway, piston 501 stretches in sleeve 502, compresses the first damping spring
507, the first damping spring 507 can play a part of first order damping and absorb buffering, and ride on rugged road surface jolting
When, because the amplitude of vibrocompression is larger, the stroke that piston 501 stretches into sleeve 502 is also larger, and then makes lead column 503 toward leading
Stretch into hole 506, sliding shoe 509 is contacted and extruded with sliding shoe 509, and compress the second damping spring 508, carry out secondary energy-absorbing
Buffering, plays second level cushioning effect, reduces the shake sense of electric bicycle, brings more to stablize to bicyclist and comfortably rides
Experience.First damping spring 507 and the second damping spring 508 constitute double damping structure, can effectively improve existing front fork
The unconspicuous shortcoming of single shock-damping structure damping effect.
Medial wall has toward the direction of piston 501 extension first annular raised 510 at the opening of sleeve 502.The bottom of piston 501
Portion lateral wall has the second annular protrusion 511 extended toward the direction of sleeve 502.Second annular protrusion 511 and first annular projection
510 coordinate.By first annular raised 510 and second annular protrusion 511 cooperation, be prevented from sleeve 502 and piston 501 and take off
Fall, strengthen the stability of whole electric bicycle front fork 100.
First annular raised 510 inner surface setting has first annular draw-in groove, and the first sealing is provided with first annular draw-in groove
Ring 512.The top outer wall of lead column 503 is provided with the second annular slot, and the second sealing ring is provided with the second annular slot
513.By the setting of the first sealing ring 512 and the second sealing ring 513, introduced contaminants such as gravel, water can be on the one hand prevented
Etc. entering in the inside of sleeve 502 and pilot hole 506, contribute to extending the service life of electric bicycle front fork 100.The opposing party
Face prevents its internal oil leakage to the external world, it is ensured that piston 501 and lead column 503 smooth can be slided.
Additionally, being additionally provided with telescopic dust cover 516 between crown 300 and damping fork leg 500, dust cover 516 is arranged
Outside piston 501.One end of dust cover 516 is connected with sleeve 502, and the other end is connected with crown 300.Dust cover 516 can enter
One step prevents impurity from adhering to the surface of piston 501, it is ensured that the clean surface of piston 501 is smooth.
In addition, during damping, piston 501 produces friction in the activity of sleeve 502 with the medial wall of sleeve 502,
Lead column 503 is slided in pilot hole 506, and it also produces friction with the medial wall of piston 501, and this kind of friction causes easily to send out
Heat, reduces the service life of piston 501 and sleeve 502.Therefore, in the present embodiment, the medial wall of sleeve 502 is provided with multiple
First louvre 514.The medial wall of piston 501 arranges multiple second louvres 515.By the setting energy of the first louvre 514
Enough increase the specific surface area of the inwall of sleeve 502, increase its area of dissipation, contribute to radiating, the service life of lengthening sleeve 502.
Equally, the specific surface area of the inwall of piston 501 can be increased by the setting of the second louvre 515, increases its area of dissipation, favorably
In the diffusion of heat, extend the service life of piston 501.
The electric bicycle front fork 100 that to sum up the present embodiment is provided is by the first damping spring 507 and the second damping spring
508 setting, constitutes dual shock absorption structure, can farthest play a part of energy-absorbing buffering, successfully manages road surface of jolting,
Stable experience of comfortably riding is provided for rideable person；Additionally, setting by the first louvre 514 and the second louvre 515 again
Meter, increases the area of dissipation of sleeve 502 and the inwall of piston 501, contributes to extending its service life.
Additionally, the present embodiment also provides a kind of electric bicycle, it includes vehicle frame and front vehicle wheel, and the front end of vehicle frame is provided with
Electric bicycle front fork 100 described above, front vehicle wheel is attached to the axle hole 505 of electric bicycle front fork 100 by wheel shaft
Place.The electric bicycle can farthest play a part of energy-absorbing buffering, successfully manage road surface of jolting, and be bicyclist carries
For experience of stably comfortably riding.
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this
For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
