Abstract
The utility model pertains to a bicycle frame, which is technically characterized in that the inclined straight beam is separated into a straight beam section and an inclined beam section through a middle axle tube. The height of the straight beam section is 5-10cm, and the included angle Alpha between the axis of the inclined beam section and the axis of the straight beam section is 10-25 degrees. Due to that the inclined straight beam is separated into the straight beam section and the inclined beam section, the utility model realizes the adjustment of the bicycle saddle height through adjusting the axle of the bicycle saddle which is arranged on the inclined straight beam, and meantime the distance between the bicycle saddle and the handle is also adjusted. For technically calculating and positioning of the straight beam section height and the inclined beam section angle, the utility model perfectly realizes the requirement of people with different heights, comfortable and energy saving demands, especially for people of different height to use. The utility model is not only suitable for manpower bicycle, but also suitable for motor bicycle.
Description
Technical field
The utility model belongs to the bicycle field, comprises bicycle and man and Electrical Bicycle, especially is applicable to the new bicycle vehicle frame of above-mentioned bicycle.
Background technology
Bicycle and Electrical Bicycle are the vehicle that people like.The vehicle frame of this two classes bicycle is the production-release design pattern at present, can not adjust, and it is very uncomfortable to ride for the lower or higher people of stature, also very requires great effort.Though the vehicle frame of this production-release design also can reduce or raises saddle by regulating saddle, but because saddle is installed on the oblique straight beam, saddle after the adjusting can not realize in the distance between human body height ratio synchronization regulation saddle and the handlebar, and therefore existing vehicle frame is unsuitable for different heights ride people's laborsaving requirement and comfortable needs.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of in human body height ratio to saddle and and handlebar between distance adjust synchronously and can realize riding that the people is comfortable, labour-saving new bicycle vehicle frame.
The utility model solves its technical matters and takes following technical scheme to realize:
This new bicycle vehicle frame, constitute by central siphon, oblique straight beam, preceding cant beam, back pole-bracket, the flat frame in back, front fork tube, central siphon installs the flat frame in back, oblique straight beam, preceding cant beam respectively, tiltedly straight beam installs back pole-bracket, front fork tube installs preceding cant beam, it is characterized in that: described oblique straight beam is made straight beam section and cant beam section respectively from the central siphon beginning, the height H of straight beam section is 5-10cm, and the angle α of the axis of cant beam section and straight beam section axis is 10-25 °.
Advantage of the present utility model and good effect are:
Because the oblique straight beam of vehicle frame is divided into straight beam section and cant beam section, like this, adjust saddle when the axial location on the oblique straight beam is regulated saddle height with regard to can be implemented in, the distance of also thereupon having adjusted between saddle and the handlebar is far and near, and the angle of the height of straight beam section and cant beam section has been carried out the calculating and the location of science, can perfect comfortable and laborsaving riding of realizing to the people that rides of differing heights, be applicable to that the people of differing heights use.The utility model not only is applicable to bicycle and man, also is applicable on the Electrical Bicycle and installs and uses.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view;
Fig. 3 is that the B of Fig. 1 is to scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
This new bicycle vehicle frame installs oblique straight beam 3, preceding cant beam 5, the flat frame 2 in back respectively on the central siphon 8, tiltedly install back pole-bracket 1 on the straight beam, on the top of this oblique straight beam saddle (present embodiment does not illustrate saddle) is installed; Install preceding cant beam on the front fork tube 6, should preceding cant beam can be one (being generally the women's bicycle type), also can install another preceding cant beam 4 jointly on front fork tube and oblique straight beam, present embodiment is two preceding cant beams, mounting knob and steering shaft on the front fork tube (present embodiment does not illustrate handle and steering shaft).Innovative point of the present utility model is: tiltedly straight beam is made straight beam section 7 and cant beam section respectively from the central siphon beginning, and the height H of the straight beam section of this oblique straight beam is 5-10cm, and the angle α of the axis of cant beam section and straight beam section axis is 10-25 °.Most preferred embodiment is: the height of straight beam section is 7cm, and angle is 16 °.
The mode of installing of each above-mentioned parts is that the general-duty welding installs.
