Abstract
The invention relates to a centrally-mounted suspension electric bicycle front fork, which comprises a fork vertical pipe, a shock absorber, two fork cylinders, and a shock absorption connector, wherein the shock absorption connector is formed by a crimp sheet, two engaging lugs, a diagonal bracing pipe and a shock absorber connecting pipe; the engaging lugs are respectively and fixedly arranged on two sides of the crimp sheet; one end of the diagonal bracing pipe is hinged on the crimp sheet between the two engaging lugs; the other end of the diagonal bracing pipe is fixedly arranged in the middle of the shock absorber connecting pipe; one end of the shock absorber connecting pipe is hinged and connected to one end of the shock absorber; the other end of the shock absorber is fixed on the crimp sheet; the fork vertical pipe is sleeved, welded and fixed with the shock absorber connecting pipe; and the two fork cylinders are respectively and fixedly arranged on the two engaging lugs. The centrally-mounted suspension electric bicycle front fork is simple in structure, scientific and reasonable in design, convenient to use, lower in cost, strong in balanced capacity, good in shock absorbing effect, and strong in stability, and the safe reliability of an electric bicycle is effectively improved.
Description
Technical field
The invention belongs to the Electrical Bicycle field, especially a kind of mid-shock-absorbing electric bicycle front fork.
Background technology
Electrical Bicycle because of its flexibly, the characteristics of convenient, energy-saving and environmental protection are in China's widespread use, Electrical Bicycle completes at the convenient main bumper arranged on two fork cylinders of shock-absorbing front fork that relies on of damping at present, although can realize to a certain extent damping, two bumpers are provided with following problem: 1, cost is higher; 2, processing technology complexity; 3, assembling is wasted time and energy; 4, balanced capacity relative reduce 5, stability and damping effect are poor.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of mid-shock-absorbing electric bicycle front fork is provided, and this front fork structure is simple, design science is reasonable, easy to use, cost is lower, balanced capacity is strong, good damping effect, stability by force, have effectively improved the safe reliability of Electrical Bicycle.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of mid-shock-absorbing electric bicycle front fork, comprise fork riser, bumper and two fork cylinders, it also comprises an impact absorbing connector, this impact absorbing connector is by bent tag, two engaging lugs, down tube and bumper connection pipe form, bent tag both sides are fixedly mounted with respectively engaging lug, hinge dress down tube one end on bent tag between two engaging lugs, the other end of this down tube is packed in bumper connection pipe middle part, this bumper connection pipe one end hinge load connects bumper one end, this bumper other end is fixed on bent tag, fork riser and bumper connection pipe suit, two fork cylinders are packed in respectively on two engaging lugs.
And described bumper is the Electrical Bicycle bumper.
And described fork riser is that bumper connection pipe one is made.
And, be fixed with a hang line frame between described fork cylinder.
And described fork cylinder bottom is connected with fork hook.
Advantage of the present invention and beneficial effect are:
1, this mid-shock-absorbing electric bicycle front fork, comprise fork riser, bumper and two fork cylinders, it also comprises an impact absorbing connector, this impact absorbing connector is by bent tag, two engaging lugs, down tube and bumper connection pipe form, bent tag both sides are fixedly mounted with respectively engaging lug, hinge dress down tube one end on bent tag between two engaging lugs, the other end of this down tube is packed in bumper connection pipe middle part, this bumper connection pipe one end hinge load connects bumper one end, this bumper other end is fixed on bent tag, fork riser and bumper connection pipe suit, two fork cylinders are packed in respectively on two engaging lugs, the damping effect of this structural reinforcing front fork, reduce the resistance of Electrical Bicycle in riding, and the service life that can improve front fork, simple in structure, design science is reasonable, easy to use, cost is lower, balanced capacity is strong, good damping effect, stability is strong, effectively improved the safe reliability of Electrical Bicycle.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the block diagram of invention;
Fig. 3 is impact absorbing connector of the present invention and bumper connection diagram.
The specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of mid-shock-absorbing electric bicycle front fork, comprise fork riser 1, bumper 4 and two fork cylinders 8, described bumper is the Electrical Bicycle bumper, also comprise an impact absorbing connector, this impact absorbing connector is by bent tag 7, two engaging lugs 6, down tube 3 and bumper connection pipe 2 form, bent tag both sides are fixedly mounted with respectively engaging lug, hinge dress down tube one end on bent tag between two engaging lugs, down tube shown in the present embodiment accompanying drawing 3 is realized connecing with the load of bent tag hinge by vertically being fixedly mounted with a short transversal pipe 11 and bearing pin 5, the other end of this down tube is packed in bumper connection pipe middle part, this bumper connection pipe one end hinge load connects bumper one end, this bumper other end is fixed on bent tag, fork riser and the welding of bumper connection pipe suit, this fork riser also can be made for bumper connection pipe one, two fork cylinders are packed in respectively on two engaging lugs.Be fixed with a hang line frame 9 between the fork cylinder, fork cylinder bottom is connected with fork hook 10.
Bumper connection pipe of the present invention and the load of bumper hinge are connected into certain angle, this angle can be between the 120-150 degree, and down tube and bent tag hinge dress up certain angle, when running into large jolting, corresponding the reducing of handlebar direction component meeting, improved the stability that the people that rides drives.
