Description
Technical field
The invention belongs to fork hook after the field of components of electric bicycle or bicycle etc., more particularly to a kind of novel tubular and
Electric bicycle comprising the fork hook.
Background technology
At present, the continuous reinforcement and the continuous maturation of bike tech and innovation realized with health of people, green living,
Electric bicycle and bicycle have become that the whole world is the simplest, the most practical and most commonly used vehicles of people.
While electric bicycle and bicycle performance are significantly lifted, electric bicycle and bicycle have gradually formed a kind of culture
And approved by more people.
Existing fork hook is usually piece type fork hook, and piece type fork hook is provided with an opening, for placing motor shaft and using screw
It is fixed.But during the use of whole bicycle, after screw loosening, motor shaft easily comes off from opening, influences to walk
Safety.Therefore, installing a safe locking plate in piece type fork hook again, even if screw loosening, electricity can also be prevented by safe locking plate
Arbor comes off from opening, and this design improves degree of safety.But when screw loosening, although motor shaft can not be from opening
Place comes off, but motor shaft still can carry out the activity of certain stroke in opening, and equally, there is also potential safety hazard.
The content of the invention
The present invention provides a kind of vehicle frame with fork hook after novel tubular, to solve to hold after motor shaft is fixed in the prior art
Caducous technical problem.
The present invention provides a kind of vehicle frame with fork hook after novel tubular, the vehicle frame include it is new after fork hook component, after this
Fork hook component further comprise for fix hind axle tubular after fork hook, space washer and clamp nut, the tubular back vent
It is in band bottom tube-like to hook, and the sidepiece of fork hook and bottom open up the pass through openings for being used to install hind axle after tubular；In assembled state,
Hind axle is entered after the tubular in fork hook by pass through openings, and space washer loads hind axle from shaft end, with tubular fork hook bottom
It is bonded on the inside of portion, its outer coordinates with tubular fork hook side inner walls, to realize the reliable location of trailing wheel in radial directions.Fastening
Nut coordinates with hind axle screw rod, compresses space washer, to lock the axial location of trailing wheel, while coordinates space washer to fix
The radial position of trailing wheel.
Vehicle frame provided by the invention, hind axle (being also referred to as motor shaft when rear wheel drive) by the outer of space washer with
The cooperation of tubular side inner walls, the positioning of its radial position is realized, the axial direction of hind axle is realized further through nut packing washer
Position is fixed.And it is to realize that the radial direction of hind axle is consolidated with the cooperation of fork hook cylinder inboard wall by the outer of nuts and washers
It is fixed, and not by frictional force, so the structure design can realize the safety and reliability that hind axle is fixed.Particularly go
The situation that above-mentioned clamp nut loosens occurs in car, hind axle will not also come off from rear fork hook, and its structure ensure that hind axle
In the reliability of radial direction.It is and the decoration structure features simple design, attractive in appearance.

Fig. 2 is the part-structure schematic diagram of vehicle frame；
Fig. 3 is a kind of new structure schematic diagram of fork hook component after the present invention；
Fig. 4 is the part cut-away view of vehicle frame.
Embodiment
A kind of referring to Fig. 1, its new structure schematic diagram for fork hook component after the present invention.The vehicle frame includes rear fork hook group
Part 22, the rear fork hook component 22 further comprise for fix hind axle tubular after fork hook 31, space washer 32 and fastening spiral shell
Mother 33.Fork hook is in band bottom tube-like after tubular.The tubular structure of fork hook 31 can be circular, square, polygon, ellipse after tubular
Any one band mouth semi-closed structure inside.In this example, tube structure and non-limiting, it is only necessary to the outer of space washer 32
With the cooperation of fork hook cylinder side inner walls.The sidepiece of fork hook 31 and bottom open up one and are used to install passing through for hind axle after tubular
Mouth 34 is opened up, specifically, the opening that the opening and bottom that sidepiece of the pass through openings 34 including fork hook 31 after tubular opens up open up,
So as in assembled state, cylinder of the hind axle 35 by fork hook after the entrance of pass through openings 34 tubular.As can be seen from Figure 2, bottom
The setting of the size and shape for the opening that portion opens up, most preferably mode are to ensure that hind axle 35 is arranged on the center of fork hook cylinder.
Space washer 32 penetrates hind axle 35 from shaft end, and its internal diameter coordinates with hind axle 35, in its outer and cylinder side
The cooperation of wall.So-called " cooperation " mechanically has a variety of structures coordinated, only needs space washer 32 and hind axle in the present invention
35 can realize the structure of positioning function i.e. it is believed that the structure that the internal diameter of space washer 32 coordinates with hind axle 35, similarly, fixed
Position packing ring diametrically realizes the structure of positioning with cylinder inboard wall, both it is believed that the outer of space washer 32 and cylinder side inner walls
The structure of cooperation.
Clamp nut 33 compresses space washer 32 on hind axle 35, to lock the axial location of hind axle 35.It please also join
Fig. 2 is read, in axial location, space washer 32 is axially fixed in after tubular between the bottom of fork hook and clamp nut 33.
In assembled state, cylinder of the hind axle 35 by fork hook 31 after the entrance tubular of pass through openings 34, space washer 32
Load hind axle 35 from shaft end, its internal diameter coordinates with hind axle 35, its outer and the cooperation of cylinder side inner walls, to realize trailing wheel
Positioning of the axle 35 in radial direction.Also, by clamp nut 33 by it axially with being radially fixed.
