Description
Technical field
This utility model relates to a kind of electric bicycle field, especially a kind of new type electric bicycle frame.
Background technology
Along with the raising of people's environmental consciousness, electric bicycle has become a kind of new vehicles and has been widely present in city
In life.
Existing electric bicycle generally comprises one vehicle frame, and head tube is installed in this vehicle frame front end, installs seat pipe, car in the middle part of vehicle frame
Frame rear end is provided with other devices such as back vent, shock-absorbing.
Ride owing to the effect of existing bicycle is the most singly supplied with human pilot, have the manned or merit of loading concurrently toward contact
Can, therefore higher to its structural rigidity requirements, the vehicle frame of said structure mainly uses a girder to install other from the head to the tail and moulds
Part and the mode of device, easily cause the problem that its stress is excessive, and when riding, more jolt in section, in the case of road conditions are poor ten
Partial volume easily causes the deformed damaged of body frame structure for automotive and the personnel of riding is caused potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, force dispersion, rigidity
Higher a kind of new type electric bicycle frame.
A kind of new type electric bicycle frame, including a front frame, this front frame leading section is provided with head tube, described front frame
Rearward end arrange diagonally downward, its bottom is installed with battery case, the vertically above installation of rearward end of described battery case
There is seat pipe, it is characterised in that: the head tube both sides that described front frame is installed are installed with the leading section of a Rear frame respectively, and these are two years old
Rear frame is symmetrically mounted on its leading section, both sides of described front frame and bends downwards, the middle part of described Rear frame rearward extension bit
Above battery case, parallel with the bottom surface of battery case in both sides, and the rearward end of described two Rear frame is all folded upward at, and symmetry is made
Kink, is installed with a luggage carrier between the upper end of described kink, the leading section of this luggage carrier and described seat pipe
Upper end fixedly mounts.
And, in the middle part of described two Rear frame between be installed with a fixed plate, described fixed plate is fixed with seat pipe lower end
Install.
And, it being separately installed with side between described both sides, front frame bottom and seat pipe and fix beam, described both sides are fixed
Beam is paralleled with the bottom surface of battery case.
And, the distance of described head tube to seat pipe is 495 to 505 millimeters.
And, the distance of described seat pipe upper end to seat pipe bottom is 340 to 360 millimeters.
And, the distance of described riser upper end to front frame bottom is 430 to 450 millimeters.
Advantage of the present utility model and good effect be:
In this utility model, front frame, Rear frame are fixed beam with side and are matched, by original erection of main beam head tube, a seat
The body frame structure for automotive of the parts such as pipe, battery case and back vent is improved, thus the stress of quality overall for vehicle body is disperseed, and makes
The stress that vehicle frame is overall in unit are is more uniformly distributed, there is in the case of vehicle frame material is constant higher rigidity；Due to
In electric motor car body, battery is the device of heavier mass, therefore installs both sides between front frame and seat pipe and fixes beam, divides further
Dissipate the vehicle frame stress of this fragment position；The size of seat pipe makes seat height lower, be suitable to more stature the shortest and the smallest ride people
Member rides, and seat pipe and head tube match the moderate dimensions holding handlebar so that riding personnel, it is simple to control the most comfortable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is front frame and the top view of rear frame portion in Fig. 1.
Detailed description of the invention
Elaborating this utility model below by embodiment, described embodiment is illustrative instead of limiting
, it is impossible to limit protection domain of the present utility model with this.
A kind of new type electric bicycle frame, including a front frame 5, this front frame leading section is provided with head tube 3, described front truck
The rearward end of frame is arranged diagonally downward, and its bottom is installed with battery case 7, the vertically above peace of rearward end of described battery case
Equipped with seat pipe 2, innovation of the present utility model is, the head tube both sides that described front frame is installed are installed with a Rear frame respectively
Leading section 4, this two Rear frame is symmetrically mounted on its leading section, both sides of described front frame and bends downwards, in described Rear frame
Portion rearward lies along both sides above battery case and parallels with the bottom surface of battery case, the rearward end 9 of described two Rear frame all to
Upper bending, symmetry is made kink, is installed with a luggage carrier 1, before this luggage carrier between the upper end of described kink
End fixedly mounts with the upper end of described seat pipe；A fixed plate 8 it is installed with between in the middle part of described two Rear frame, described fixing
Plate fixedly mounts with seat pipe lower end.
In the present embodiment, between described both sides, front frame bottom and seat pipe, it is separately installed with side fixes beam 6, described
Both sides are fixed beam and are paralleled with the bottom surface of battery case.
In the present embodiment, the distance of described head tube to seat pipe is 495 to 505 millimeters；Described seat pipe upper end is under seat pipe
The distance of end is 340 to 360 millimeters；Described riser upper end is 430 to 450 millimeters to the distance of front frame bottom.
Work process of the present utility model is:
During utility model works, when the personnel that ride are at head tube front end installation bicycle basket, and in bicycle basket and luggage carrier respectively
In the case of loading, the weight of vehicle frame entirety will dramatically increase, and front frame, Rear frame and luggage carrier match and vehicle frame can be made whole
The stress of body is more uniformly distributed dispersion.
In this utility model, front frame, Rear frame are fixed beam with side and are matched, by original erection of main beam head tube, a seat
The body frame structure for automotive of the parts such as pipe, battery case and back vent is improved, thus the stress of quality overall for vehicle body is disperseed, and makes
The stress that vehicle frame is overall in unit are is more uniformly distributed, there is in the case of vehicle frame material is constant higher rigidity；Due to
In electric motor car body, battery is the device of heavier mass, therefore installs both sides between front frame and seat pipe and fixes beam, divides further
Dissipate the vehicle frame stress of this fragment position；The size of seat pipe makes seat height lower, be suitable to more stature the shortest and the smallest ride people
Member rides, and seat pipe and head tube match the moderate dimensions holding handlebar so that riding personnel, it is simple to control the most comfortable.
