Abstract
The utility model relates to an electric bicycle, in particular to an improved electric bicycle frame. According to a technical proposal of the utility model, a level breeches pipe is connected with a min beam and a stand pipe; the utility model is characterized in that a lower part of the stand pipe is connected with the main beam through an arched top pipe, a space in which a battery box can be arranged is formed below the stand pipe, above the level breeches pipe and the main beam, and left below the top pipe. The stand piece is connected with a left end of the level breeches pipe through an arched vertical breeches pipe. A supporting pipe is arranged between the lower part of the top pipe and the main beam. The utility model has the advantages of effectively lowering the center of gravity of the electric bicycle, easily being operated by a driver and improving intensity of the electric bicycle frame.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle, refers in particular to a kind of improvement to the Electrical Bicycle vehicle frame.
Background technology
In the prior art, the body frame structure for automotive of Electrical Bicycle, owing to be subjected to the restriction in space, after laying electrokinetic cell, it is very inharmonious that car body and battery seem, has influence on the outward appearance and the in-use performance of car load.As shown in Figure 1, battery case 8 is placed on the front side of cant beam 9 or column 10, has both influenced outward appearance, has played tall, and has influence on the intensity of vehicle frame again, returns the user and gets on or off the bus and make troubles; As be placed on the rear side of column 10, and then force vehicle frame length to increase, also can have influence on the intensity of vehicle frame simultaneously.Therefore, these several places are not the optimum position of placing battery on the vehicle frame.But be placed on other places, insufficient space seems again.
The utility model content
The purpose of this utility model is a kind of Electrical Bicycle vehicle frame of design, for laying of battery provides a suitable space, and can reduce the car load center of gravity, makes things convenient for the rider to use, and improves frame strength.
According to design plan of the present utility model, chain stay pipe and girder and standpipe interconnect, it is characterized in that: the lower end of standpipe utilizes the arc pipe of going up to be connected with girder, below standpipe, the chain stay pipe and above the girder, between the lower left of pipe space that can hold battery case of formation.
Between the left end of standpipe and chain stay pipe, be connected arc upright breeches pipe.Between the bottom of last pipe and girder, support tube is set.
The utility model has the advantages that: because seat tube is the disconnection shape, below standpipe, the chain stay pipe with above the girder, on form a space that is enough to hold battery case between the lower left of pipe, provide convenience to laying of battery; And vehicle frame need not extend, and does not influence the user and gets on or off the bus; Simultaneously, the center of gravity of this structure is lower, and stability is relatively good.
Description of drawings
Fig. 1 is original body frame structure for automotive figure.
Fig. 2 is body frame structure for automotive figure of the present utility model.
Fig. 3 is the constitution diagram after placing battery case on the vehicle frame.
The specific embodiment
As shown in Figure 2: chain stay pipe 7 interconnects with girder 6 and standpipe 3, the lower end of standpipe 3 utilizes the arc pipe 4 gone up to be connected with girder 6, below standpipe 3, chain stay pipe 7 and above the girder 6, on form the space 2 that can hold battery case 8 between pipe 4 the lower left, between the left end of standpipe 3 and chain stay pipe 7, be connected arc upright breeches pipe 1, between the bottom of last pipe 4 and girder 6, support tube 5 be set.
In order to guarantee the frame strength after seat tube 3 disconnects, the design adopts bow-shaped structural, to disperse the stressed of standpipe 3.As shown in Figure 2, standpipe 3 is connected in arc upright breeches pipe 1 and arc going up managed on 4 bow members of forming, and forms an arch configuration, and standpipe 3 is positioned at the top of arch configuration.The gravity of human body passes on the bow member by standpipe 3, respectively power is distributed on the chain stay pipe 7 and girder 6 that is positioned at the bottom by arc upright breeches pipe 1, the arc pipe 4 of going up again.Be the problem that disconnects the strength degradation that shape brought with regard to having remedied because of standpipe 3 like this.In addition in order to increase the intensity of girder, its weakness add a support tube 5 with on pipe 4 be connected.
Claims (3)
1, Electrical Bicycle vehicle frame, comprise interconnective chain stay pipe (7) and girder (6), and standpipe (3), it is characterized in that: the lower end of standpipe (3) utilizes the arc pipe (4) of going up to be connected with girder (6), below standpipe (3), chain stay pipe (7) forms the space (2) that can hold battery case (8) with above the girder (6) between the lower left of last pipe (4).
2, vehicle frame according to claim 1 is characterized in that: be connected arc upright breeches pipe (1) between the left end of standpipe (3) and chain stay pipe (7).
3, vehicle frame according to claim 1 is characterized in that: between the bottom of last pipe (4) and girder (6) support tube (5) is set.
