How the battery of electric bicycle is placed, and has many molding schemes, such as Chinese patent at present
CN201621219939.8 discloses " a kind of new type electric bicycle damping frame ", and as shown in its Fig. 2, battery 18 is placed in three
The inside of angle vehicle frame.For another example " a kind of electric bicycle " disclosed in Chinese patent CN201621256318.7, battery component 5 is pacified
It is placed on the upside of back vent.Chinese patent CN201621180425.6 discloses " a kind of electric bicycle battery box ", Battery case 6
It is arc-shaped, it is arranged at trailing wheel upside and within the gap of dickey seats, the battery of this kind design is less susceptible to take out repair or independent
It charges, and rear vehicle is made to seem too fat to move, it is less beautiful.Chinese patent CN201620613957.8 discloses " electric bicycle
Battery pack mounting structure ", battery pack is arranged in bicycle beam, this is also at present but the bicycle beam using a kind of more mode
Limited volume or extension bicycle beam length or increasing bicycle beam cross section after all, the battery that can be accommodated have certain volume limit
System.
Utility model content

Specific embodiment
The utility model electric bicycle fame is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1,3, electric bicycle fame includes bicycle beam 1, head tube 2, seat pipe 3, before which is fixed on bicycle beam 1
End, the vehicle frame also have battery case 4, which is fixed on 1 rear end of bicycle beam, and fixed lateral sets five on the downside of battery case
Siphunculus 5, for the Five-way tube 5 for installing axis, which sets chain drum, and back vent 6, the electricity is fixedly installed on rear side of battery case
Fixed setting seat pipe 3 on the inside of the box of pond.Placement cell body in the battery case.
The back vent 6 has Seat stay 61 and Chain stay 62, which is fixed on battery case 4, the Seat stay
Connector 7 is fixedly installed between 61 and battery case 4, which can play back vent certain cushioning effect.The connector
7 tail ends dispose tail-light 71.
As shown in Figure 1, 2, seat pipe 3 is arranged at the rear side position in battery case 4.The seat pipe 3 is integrated with 4 housing of battery case
Formula molding structure, it is both easy to manufacture, also ensure the high stability that seat pipe 3 is connected with battery case 4.On the battery case 4
Side has the upper cover 41 being obliquely installed, and the angularly disposed smooth downslide that can effectively ensure that rainwater of the upper cover 41 is water stain to will not fall into
The inside of battery case 4 is so as to influencing the service life of battery.And when the upper cover 41 is opened, smoothly cell body can be extracted
Come, individually charge or safeguard all seeming very convenient.
1 middle part of bicycle beam is provided with locking device 8, which has folding joint 81, quick-release handle 82.The lock
Tight device 8 is the eccentric device for quickly disassembling that can be opened or closed.Since the folding joint being used on folded bicycle belongs to the prior art,
