The specific embodiment

Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and advantage thereof are further described.

As shown in Figure 1, Electrical Bicycle vehicle frame described in the utility model mainly comprises pipe 1 down, center tap reinforced rib 2, and center tap 3, standpipe 4, battery case base plate 5, upright breeches pipe 6, upright fork bridge tube 7, chain stay pipe 8, described center tap place down the pipe upper end; The position at standpipe rear portion.

Fig. 2-Fig. 5 is an Electrical Bicycle vehicle frame preferred embodiment of the present utility model, as shown in Figure 2, under manage 1 on the right the top near end position with " fourth " shape standpipe 4 lower end captive joints, this time pipe 1 right-hand end is with lower end, center tap reinforced rib 2 right side captive joint, these reinforced rib 2 tops are from left to right respectively with center tap 3 peaceful breeches pipe 8 captive joints, chain stay pipe 8 left sides are with standpipe 4 rear portion captive joints, the right is with upright breeches pipe 6 captive joints, thereby make center tap 3 place down the position at pipe 1 upper end standpipe 4 rear portions, owing to adopted said structure, reduce the height of time pipe, be convenient to getting on or off the bus of rider.

In addition, as shown in Figure 2, captive joint with the standpipe upper rear in upright breeches pipe 6 tops, and 2 forks of upright breeches pipe 6 are captiveed joint with 2 forks of chain stay pipe respectively.Battery case base plate 5 is arranged on the center tap top, and respectively at front end, promptly left end is connected with the standpipe rear side, and in the rear end, promptly right-hand member is connected with chain stay pipe top.The A of chain stay pipe 8 is to view in Fig. 3 presentation graphs 2, and the B of Fig. 4 presentation graphs 2 neutral breeches pipes 6 is to view.

Fig. 6-Fig. 9 is another implementation column of the utility model Electrical Bicycle vehicle frame, and structure is basically with Electrical Bicycle vehicle frame shown in Figure 2, and difference is that upright breeches pipe 6 has adopted double pipe structure, so that the unitized frame structural strength to be provided.

In this specification sheets, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
