Description
Technical field
The utility model relates to two-wheel car technical field, especially a kind of electric two-wheel vehicle frame.
Background technology
Battery-driven car is a kind of very practical walking-replacing tool, and its riding speed is very fast, and load-carrying is larger, and pollution-free to natural environment, is more and more subject to liking of people.But along with the raising of the battery-driven car speed of a motor vehicle and load carrying ability, requirement to car load mechanical strength is also more and more higher, in battery-driven car, the main part that plays support, connecting components is vehicle frame, more common body frame structure for automotive is at present: comprise girder, be fixedly mounted with front fork sleeve pipe at the front end of girder, saddle sleeve pipe is installed at middle part at girder, make trailing wheel connecting panel in the rear end of girder, girder bilateral symmetry installation foot pedal between front fork sleeve pipe and saddle sleeve pipe, between saddle sleeve pipe and trailing wheel connecting panel, a cant beam is installed, this cant beam and trailing wheel connecting panel are fixedly mounted with back seat bracing frame jointly.In said structure, can find out that the cant beam between the trailing wheel connecting panel of saddle sleeve pipe and main beam rear end has played the effect that increases vehicle frame rear portion mechanical strength, but from the structure of current battery-driven car, the center of gravity of battery-driven car is in the front side of girder, be that the main stress point of vehicle frame is near girder stretcher and saddle sleeve pipe, so the vehicle frame of existing structure is not reinforced this part structure, certainly can adopt steel pipe that wall thickness is larger or more high-intensity material to improve the mechanical strength of vehicle frame, but this will certainly increase weight and the cost of car load, strengthen user's economical burden.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of a kind of electric two-wheel vehicle frame of firm in structure, flexible operation is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of electric two-wheel vehicle frame, comprises main body of vehicle frame, and main body of vehicle frame is made up of front support beam, front fork sleeve pipe, front shock absorber, handlebar, Battery case, rear support beam, rear chain stay, rear shock absorber, seat fixed mount, luggage carrier, main body of vehicle frame front end is provided with front fork sleeve pipe, on front fork sleeve pipe, be provided with front shock absorber, described front fork cannula tip is provided with handlebar, described main body of vehicle frame middle part is provided with Battery case, this Battery case is by upper, lower battery protection frame is fixed on main body of vehicle frame middle part, described front fork sleeve pipe is connected with Battery case front end by front support beam, described main body of vehicle frame rear portion is provided with the rear chain stay with Battery case hinge dress, be installed in the rear support beam on battery fender bracket, be installed on the rear shock absorber of rear support beam bottom, be installed on rear support beam top seat fixed mount and be arranged at the luggage carrier of seat fixed mount end.
And described handlebar adopts 4 fixing handlebars of separation type.
And described rear chain stay and rear shock absorber angle are 45 °-60 °.
And described rear support beam adopts broken-line type to be inclined upwardly, angle is 120 °-145 ° inside support beam, forms nearly diamond structure with rear shock absorber, rear chain stay.
And described back seat fixed mount adopts broken-line type bend pipe, angle is 30 °-45 ° inside bend pipe, and it is 10 °-20 ° that bend pipe back segment is inclined upwardly with horizontal sextant angle.
Advantage of the present utility model and economic effects are:
1, to have overcome conventional electric two-wheel car mechanical strength low for the utility model; operate not nimble technical barrier; by adopting upper and lower battery protection frame that Battery case is fixed on to main body of vehicle frame middle part; make Battery case as the part in body frame structure for automotive; not only strengthen the structural strength of vehicle frame entirety; and reduced the center of gravity of vehicle frame, strengthen the stability of vehicle frame entirety.
2, the utility model adopts 4 fixing handlebars of separation type, makes operation more nimble, not only can regulate voluntarily handlebar height according to user's operating habit, and more easily change in the time that handlebar damages.
3, the utility model adopts the acclivitous rear support beam of broken-line type, form nearly diamond structure with rear shock absorber, rear chain stay, both increased the stroke of rear shock absorber, make that the suffered power of rear shock absorber and rear chain stay is uniform to be dispersed on rear support beam simultaneously, effectively increase the load-carrying capacity of trailing wheel, and the mechanical strength at vehicle frame rear portion.
4, in the utility model, back seat fixed mount adopts broken-line type bend pipe, and in the time of assembling, broken-line type bend pipe is outside exposed, can make the rear row passenger who takes select own actv. fixed form according to oneself custom, has greatly improved the safety that rear row passenger takes.
