Abstract
The utility model discloses a reinforced electric bicycle frame, which is characterized by comprising a sealed side pipe, a main beam pipe, a forefront pipe, a battery bottom support and a seat bucket bracket, wherein the sealed side pipe is step-shaped and has a low front part and a high back part; the main beam pipe is vertically fixed at the front end of the side pipe; the main beam pipe further comprises an arc connecting pipe arranged at two sides of the main beam pipe, one end of the arc connecting pipe is fixed on the main beam pipe through a fixing piece, and the other end is fixed at the front end of the side pipe through the fixing piece; the forefront pipe is aslant fixed at the upper end of the main beam pipe, the battery bottom support is arranged below the middle part of the side pipe; the seat bucket is fixed at the middle part of the side pipe. The reinforced electric bicycle frame provided by the utility model is high in strength, not easy to break and long in service life; particularly the main beam pipe and the side pipe have three connection points, so that even the frame is suffered from the impact of strong external force, the main beam pipe does not crack on the frame or separate from the frame.
Description
Technical field
The utility model relates to electric bicycle fame field, is specifically related to a kind of main-beam pipe is fixed on to the electric bicycle fame on vehicle frame intentinonally.
Background technology
Electrical Bicycle is with its environmental protection, feature easily, universal on a large scale, and along with the expansion of market scale, battery-driven car market is also in segmentation day by day, and user is day by day personalized to the demand of battery-driven car.
And vehicle frame is the important component part of battery-driven car, existing rack for electric motor car, the connection mode between main-beam pipe and vehicle frame is mainly that main-beam pipe is welded on the pipe of limit.If application number is 201220257758.X, name is called " simple electromobile frame " described main-beam pipe and is vertically fixed on the front end of described limit pipe.The vehicle frame of this structure, not only welding operation difficulty in manufacturing process, limit pipe only has place welding with main-beam pipe, insufficient strength, vehicle frame bend pipe angle is unstable causes vehicle frame offset dimensions, and is in use very easy to find phenomenon of rupture.
Therefore, need to make improvements.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of Enhanced electric cycle frame, change three into by point of connection main-beam pipe being fixed on the pipe of vehicle frame limit, reach the external force of disperseing main-beam pipe to be subject to, promote frame strength, make its not easy fracture, the object of long service life.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Enhanced electric cycle frame, comprises
The limit pipe of sealing, is low early and high after stepped;
Main-beam pipe, is vertically fixed on the front end of described limit pipe; Described main-beam pipe also comprises the arc connection pipe of being located at main-beam pipe dual-side; One end of arc connection pipe is fixed on main-beam pipe by connecting element, and the other end is fixed on the front end of limit pipe by connecting element;
Front tubulation, is fixed on the upper end of described main-beam pipe obliquely;
Battery collet, is located at below the middle part of described limit pipe;
Seat bucket support, is fixed on the middle part of described limit pipe.
Preferably, the two ends of described arc connection pipe are flats structure, middle for having the connection pipe of corrugated tube wall.
By the enforcement of above technical scheme, the utlity model has following beneficial effect:
Main-beam pipe of the present utility model bottom dual-side is respectively equipped with one and manages with limit the arc connection pipe being connected, and the external force that arc connection pipe can disperse main-beam pipe and limit pipe point of connection to be subject to significantly, has strengthened the be connected power of main-beam pipe with main body of vehicle frame; Extend the service life of vehicle frame; Make vehicle frame in the time being subject to stronger external force impulse force, main-beam pipe also can not ftracture or depart from from vehicle frame on vehicle frame.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.
Embodiment 1.
As shown in Figure 1-Figure 3, a kind of Enhanced electric cycle frame, comprises
The limit pipe 1 of sealing, is low early and high after stepped;
Main-beam pipe 2, is vertically fixed on the front end of described limit pipe 1; Described main-beam pipe 2 also comprises the arc connection pipe 21 of being located at main-beam pipe 2 dual-sides; One end of arc connection pipe 21 is fixed on main-beam pipe 2 by connecting element, and the other end is fixed on the front end of limit pipe 1 by connecting element;
Front tubulation 3, is fixed on the upper end of described main-beam pipe 2 obliquely;
Battery collet 4, is located at below the middle part of described limit pipe 1;
Seat bucket support 5, is fixed on the middle part of described limit pipe 1.
Described arc connection pipe is one-body molded, and its two ends are flats structure 21-2, middle one-tenth approximate circle tubular structure; The two ends of described arc connection pipe are respectively equipped with a through hole, on corresponding main-beam pipe and limit pipe, are also provided with corresponding through hole; Arc connection pipe and main-beam pipe and limit pipe can well be fitted, and by bolt, arc connection pipe are fixed on main-beam pipe and limit pipe.
In order to make arc connection pipe 21 dispersive stress better, middle for thering is the connection pipe 21-1 of corrugated tube wall.
By the enforcement of above technical scheme, the utlity model has following beneficial effect:
Main-beam pipe of the present utility model bottom dual-side is respectively equipped with one and manages with limit the arc connection pipe being connected, and the external force that arc connection pipe can disperse main-beam pipe and limit pipe point of connection to be subject to significantly, has strengthened the be connected power of main-beam pipe with main body of vehicle frame; Extend the service life of vehicle frame; Make vehicle frame in the time being subject to stronger external force impulse force, main-beam pipe also can or not depart from from vehicle frame at vehicle frame cracking.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
