Using linear structure, structure is subjected to displacement damper by spring-compressed, and the direction of displacement moves along a straight line along unit for front fork tube,
Realize shock-proof effect, the direction of shock-proof front-fork assembly stress is with the front upper place transmitting between 65 degree to 75.
Summary of the invention
The problem of in order to solve under the prior art, traditional vehicle frame side pipe straight line connects girder, the intensity decline that leads to that overlapped,
The utility model provides a kind of enhanced electric bicycle fame, and structure can be such that vehicle moves by active force acting
When, be conducive to act on force resolution and transfer, enhance vehicle frame self-strength, the resultant force of active force is transported to front transfer and vehicle upwards
Dynamic direction is consistent.
Technical solution used by the utility model is as follows:
A kind of enhanced electric bicycle fame, including inclined U-shaped girder, the front end front connection of the U-shaped girder
Head tube, rear end top connect seat board, and the lower part rear of the U-shaped girder, which passes through after five-way connecting piece connects V-arrangement square tube, puts down
The front end of fork, the rear end of the chain stay seat board described by damper connection after the V-arrangement square tube, under the U-shaped girder
Battery case edge strip, the battery case edge strip interior welds battery case, the rear two of the battery case edge strip are welded in front of portion
Left chain guard and right chain guard is respectively welded in side.
Clothes hanger after square tube is connected with below seat board.
The damper upper end seat board described by connector connection in damping, the damper lower end passes through under damping
The rear end of chain stay after the connector connection V-arrangement square tube.
U-shaped girder includes upper tube after upper tube and girder before the girder being parallel to each other, before the girder after upper tube and girder on
Pipe lower end is connected by girder transverse tube；Chain stay includes fork and rear chain stay lower fork on rear chain stay after the V-arrangement square tube, flat after described
It is pitched on fork and the angle of rear chain stay lower fork is 54 degree；Upper tube is parallel with fork on rear chain stay after the girder, rear chain stay lower fork with
Horizontal plane is parallel, and the horizontal vertical line of the five-way connecting piece is in the front end of seat board.
Battery inside placing battery group, the battery pack are at least 2 pairs, the U-shaped being placed in battery case respectively
Two sides below girder.The structure that the advantage put in this way contributes to vehicle can be realized the location mid-shaft of new national standard, so that electric
Pond box is more steady, balance.
Technical solution provided by the utility model has the benefit that
When being moved by active force acting, U-shaped main beam stress is uniform, and intensity increase is not easy bend fracture, chain stay after V-arrangement
There is a damper to connect with U-shaped girder, improves vehicle and ride stationarity, safety.
The utility model compared with prior art, have design is scientific and reasonable, easy to use, shock-proof effect is smoothly special
Point.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is a kind of Integral connection structure schematic diagram of enhanced electric bicycle fame of the utility model；
Fig. 2 is a kind of battery case Integral connection structure schematic diagram of enhanced electric bicycle fame of the utility model.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Embodiment one
As shown in attached drawing 1,2, a kind of enhanced electric bicycle fame, including inclined U-shaped girder 1, the U-shaped girder
