Abstract
A front fork device of electrical bicycle comprises a fork vertical pipe, the first fork pipe and the 2nd fork pipe; the first fork pipe and the 2nd fork pipe are fixed and arranged on the fork vertical pipe; the second fork pipe is shorter than the first fork pipe; the second fork pipe is provided with at least two connection parts. While in use the front fork device for the electrical bicycle of the utility model, the motor can be fixed and arranged on the first fork pipe with shorter length; at the same time the motor is also provided with two mounting holes which cooperates each other, to form bolt-fixing between the fork pipe and the motor; the utility model has advantages as below: simple structure; convenient installation; also a decreased weight for the whole electrical bicycle.
Description
Technical field
The utility model relates to the parts of battery-driven car, is specifically related to a kind of front fork unit of battery-driven car.
Background technology
Battery-driven car is to popularize a kind of vehicle that use in recent years, its vehicle wheel driving mode mainly contains two kinds: a kind of is traditional wheel hub motor drive mechanism, another kind is that a circle gear ring is set on wheel, one miniature gears is set on the motor output shaft, come drive wheels by miniature gears direct drive gear circle, for example disclosed portable electric car in the Chinese patent application 03219888.4.In this battery-driven car, in order to want the fixed electrical machinery device, be provided with motor mounting plate and motor hold-down bolt at the back vent place of vehicle frame, whole device is complex structure not only, and installs loaded down with trivial details.
When the motor with battery-driven car is installed on front-wheel, when constituting the f-w-d structure, also there is same problem, promptly because the restriction of installation position, motor is difficult to be fixed, and the gear drive structure is higher to the positioning requirements of motor, if motor can not be located well, will cause the rapid decline of gear drive structure efficiency.
Traditional front fork is the both arms suspended structure, on the minority motor bike, there is the single-arm suspension structure, though the single-arm suspension structure can be vacated a side as the motor installation position, yet, need to increase the support strength of breeches pipe, and higher to the designing requirement of balance, thereby be not adapted at using on the battery-driven car.
Summary of the invention
The utility model purpose provides a kind of front fork unit of battery-driven car, and it need not to add just fixed electrical machinery thereon of extra anchor fitting, and is simple in structure, and fixed installation is convenient.
For achieving the above object, the technical solution adopted in the utility model is: a kind of front fork unit of battery-driven car, comprise fork standpipe, first breeches pipe and second breeches pipe, described first breeches pipe and second breeches pipe are arranged on the described fork standpipe regularly, described second breeches pipe be shorter in length than first breeches pipe, be set with at least two links on described second breeches pipe.
In the technique scheme, described link is installation sheet or the mounting rod that is arranged on the second breeches pipe both sides, and described installation sheet or mounting rod are provided with mounting hole.
Described link is arranged on the both sides of second breeches pipe symmetrically.
In the technique scheme, the length of described second breeches pipe be first breeches pipe 1/10th to 1/2nd between.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. because second breeches pipe of the present utility model is shorter in length than the length of first breeches pipe, and on second breeches pipe, be provided with two mounting hole site symmetrically, therefore motor can be fixedly installed on the first short breeches pipe of length, two mounting hole site that match also are set on motor simultaneously, make between breeches pipe and the motor and form bolt, simple in structure, easy for installation, also alleviated the weight of whole device.
2. cooperate with motor, front fork of the present utility model still constitutes the both arms suspended structure, does not need thus other parts of car load are adjusted, and can directly replace existing double-arm front fork, and is easy to use.

Wherein: 1, fork standpipe; 2, first breeches pipe; 3, second breeches pipe; 4, link; 5, mounting hole.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: shown in accompanying drawing 1 to 2, a kind of front fork unit of battery-driven car, comprise fork standpipe 1, first breeches pipe 2 and second breeches pipe 3, described first breeches pipe 2 and second breeches pipe 3 are arranged on the described fork standpipe 1 regularly, described second breeches pipe 3 be shorter in length than first breeches pipe 2, be provided with two links 4 at least on described second breeches pipe 3.
In the present embodiment, described link 4 is for being arranged on the installation sheet or the mounting rod of second breeches pipe, 3 both sides, and described installation sheet or mounting rod are provided with mounting hole 5.
Described link 4 is arranged on the both sides of second breeches pipe 3 symmetrically.
In the present embodiment, the length of described second breeches pipe 3 be first breeches pipe 2 1/10th to 1/2nd between.
Embodiment two: shown in accompanying drawing 3 and accompanying drawing 4, when front fork described in the utility model is arranged on the front-wheel of battery-driven car, described front fork can cooperate corresponding motor, this motor is fixedly installed on the first short breeches pipe 2 of length, simultaneously two mounting hole site that match are set also on motor, make between first breeches pipe 2 and the motor and form bolt, simple in structure, easy for installation, also alleviated the weight of whole device.
