Another goal of the invention of the utility model is that rotating with wheel can not appear in the hind axle of this vehicle frame, and the trailing wheel connecting strap can not go out the phenomenon of fracture.
The technical solution of the utility model is: design a kind of multifunctional motor-driven cycle frame, comprise support, afterbody at described support is provided with trailing wheel bindiny mechanism, described trailing wheel bindiny mechanism comprises trailing wheel connecting strap and strut bar connecting strap, described trailing wheel connecting strap is captiveed joint with described support afterbody, above described trailing wheel connecting strap, be provided with at least one connecting bore, below the trailing wheel connecting strap, be provided with the strip shape trailing wheel link slot that extends back of an opening, on described strut bar connecting strap, be provided with the hole with the corresponding position of described connecting bore, screw rod passes the hole and is connected with described connecting bore, and described trailing wheel connecting strap and strut bar connecting strap are fastenedly connected; And make one of the strip shape trailing wheel link slot bottom formation of described strut bar connecting strap and described trailing wheel connecting strap be beneficial to hind axle gap up and down.
Above the strip shape trailing wheel link slot of described trailing wheel connecting strap, be provided with a flat groove, be provided with the pad of a two ends buckle in described trailing wheel connecting strap one side, the hook of described pad is hooked in the flat groove respectively and the downside of trailing wheel link slot outside.
Described trailing wheel bindiny mechanism also comprises tread plate, is provided with adjustable standing screw on described pedal plate, and described screw rod can withstand on the nut of trailing wheel axis.
Described mid-stent be provided with can the horizontal positioned storage battery the storage battery container.
The utility model is provided with at least one connecting bore owing to having adopted above described trailing wheel connecting strap, below the trailing wheel connecting strap, be provided with the strip shape trailing wheel link slot that extends back of an opening, on described strut bar connecting strap, be provided with the hole with the corresponding position of described connecting bore, screw rod passes the hole and is connected with described connecting bore, and described trailing wheel connecting strap and strut bar connecting strap are fastenedly connected; And a structure that is beneficial to hind axle gap is up and down formed at the strip shape trailing wheel link slot bottom that makes described strut bar connecting strap and described trailing wheel connecting strap, like this, when maintenance Electrical Bicycle trailing wheel, just do not need to unload earlier other parts, and only need become flexible the nut at trailing wheel axis two ends, just can take off or load onto the trailing wheel of repairing from opening position easily.Secondly owing to adopted above the strip shape trailing wheel link slot of described trailing wheel connecting strap, be provided with a flat groove, be provided with the pad of a two ends buckle in described trailing wheel connecting strap one side, the hook of described pad is hooked in the flat groove respectively and the structure of the downside outside the trailing wheel link slot, like this, can strengthen the intensity of trailing wheel connecting strap link slot by the pad of the two ends buckle that adds, in case the fracture of the outside of link slot, and prevent that the trailing wheel axis from rotating with trailing wheel; Moreover, owing to adopted described trailing wheel bindiny mechanism also to comprise tread plate, be provided with adjustable standing screw on described pedal plate, described screw rod can withstand on the structure on the spindle nut in the trailing wheel, can further reduce the possibility that the trailing wheel axis rotates with trailing wheel; Again and since adopted described mid-stent be provided with can the horizontal positioned storage battery the storage battery container, can make things convenient for the placement of storage battery, and make whole decline of center of gravity of Electrical Bicycle, improve the stability of Electrical Bicycle.
