Description
Technical field
The utility model belongs to Electrical Bicycle technical field, especially relates to a kind of electric bicycle fame.
Background technology
Bicycle is the one conveniently vehicle, and people generally use bicycle as trip instrument on and off duty with during outing.In order to make bicycle user time saving and energy saving, usually adopt the electrical motor driven by storage battery as propulsive effort.Existing Electrical Bicycle generally comprises car body, is contained in the storage battery on car body, and is connected, drives the electrical motor of rear wheel with storage battery.Described Electrical Bicycle mainly relies on the electrical energy drive electrical motor of storage battery to rotate, and then drive rear wheel, driving Electrical Bicycle advances, but motor and bicycle body's junction complicated structure in the prior art, increase car body volume, and bicycle rack is firm not to the solid timing architecture of motor.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, to the fixing more electric bicycle fame of the motor of Electrical Bicycle.
The technical solution of the utility model is: a kind of electric bicycle fame, comprise head tube, upper pipe, middle pipe, lower pipe, Seat stay, Chain stay, five-way and snap fit, the front end of described upper pipe and lower pipe is all connected and fixed with head tube, described upper pipe rear end and middle pipe upper end are connected and fixed, described lower pipe rear end and middle pipe lower end are connected and fixed, the lower end of described middle pipe is fixedly connected with five-way, described upper pipe, middle pipe and lower pipe are encircled into triangle, described Seat stay and Chain stay one end are fixedly connected with middle pipe top and bottom respectively, described Seat stay is all fixedly connected with snap fit with the other end of Chain stay, pipe bracket and lower pipe bracket in the downside of described middle pipe and lower pipe is respectively arranged with, motor sleeve is fixed with between described middle pipe bracket and lower pipe bracket.
Further, described motor sleeve is positioned within the triangle that described top tube, middle tube, and down tube are encircled into.
Further, the barrel of described motor sleeve is provided with some mounting holes along on the axial direction of cylindrical shell.
Further, the quantity of described mounting hole is four, and described mounting hole is separated by 90 degree of settings.
Further, the inwall of described motor sleeve is provided with protective pad.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, by welding motor sleeve on electric bicycle fame, by motor sleeve, motor is fixed, simplify frame structure of electric bicycle, make electric bicycle fame more succinct, the barrel of motor sleeve is provided with some mounting holes along on the axial direction of cylindrical shell, motor is done further fixing by mounting hole, structure is simple, Stability Analysis of Structures.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in the structural representation that Fig. 1 the utility model provides, the utility model provides a kind of electric bicycle fame, comprise head tube 1, upper pipe 2, middle pipe 3, lower pipe 4, Seat stay 5, Chain stay 6, five-way 7 and snap fit 8, the front end of described upper pipe 2 and lower pipe 4 is all connected and fixed with head tube 1, described upper pipe 2 rear end and middle pipe 3 upper end are connected and fixed, described lower pipe 4 rear end and middle pipe 3 lower end are connected and fixed, the lower end of described middle pipe 3 is fixedly connected with five-way 7, described upper pipe 2, middle pipe 3 and lower pipe 4 are encircled into triangle, described Seat stay 5 and Chain stay 6 one end are fixedly connected with middle pipe 3 top and bottom respectively, described Seat stay 5 is all fixedly connected with snap fit 8 with the other end of Chain stay 6, pipe bracket 9 and lower pipe bracket 10 in the downside of described middle pipe 3 and lower pipe 4 is respectively arranged with, motor sleeve 11 is fixed with between described middle pipe bracket 9 and lower pipe bracket 10, described motor sleeve 11 is positioned at described upper pipe 2, within the triangle that middle pipe 3 and lower pipe 4 are encircled into.
The barrel of described motor sleeve 11 is provided with some mounting holes 12 along on the axial direction of cylindrical shell, and the quantity of described mounting hole 12 is four, and described mounting hole 12 is separated by 90 degree of settings.
The inwall of described motor sleeve 11 is provided with protective pad 13.
The working process of this example: when using the utility model to provide electric bicycle fame, upper pipe 2, the triangle that middle pipe 3 and lower pipe 4 are encircled into, pipe bracket 9 and lower pipe bracket 10 in the downside of middle pipe 3 and lower pipe 4 is respectively arranged with, motor sleeve 11 is fixed with between middle pipe bracket 9 and lower pipe bracket 10, like this motor sleeve 11 and electric bicycle fame are combined, simplify the structure of electric bicycle fame, mounting hole 12 pairs of motors again by arranging on motor sleeve 11 barrel are fixed, fixing more firm, the quantity of mounting hole 12 is four, described mounting hole 12 is separated by 90 degree of settings, rational in infrastructure, connect more reliable, the inwall of motor sleeve 11 is provided with protective pad 13, when motor penetrate motor sleeve 11 pairs of motors do further fixing time, motor sleeve 11 pairs of motors can be prevented wearing and tearing.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
