Detailed description of the invention
Electrical Bicycle of the present utility model comprises: vehicle frame and be arranged on wheel, the handle etc. on vehicle frame, on vehicle frame, be provided with frame tube, and the internal cavities of frame tube can be in order to placing battery.
Core of the present utility model is frame tube, describes the structure of the utility model frame tube below with reference to specific embodiment in detail.
Consult Fig. 1 and Fig. 2, the frame tube of the present embodiment comprises: one is arranged on the reinforced tube 4 on main body tube 2 in order to hold the main body tube 2 and of battery.
Main body tube 2 is hollow tubular structure, and the inner chamber 26 of its hollow can be in order to hold battery.The profile of main body tube 2 is prolate shape, to match with the prolate shape battery on existing market.Main body tube 2 comprises four tube walls, and wherein, the first tube wall 21 is relative with the 4th tube wall 24 and size is narrower, and the second tube wall 22 is relative with the 3rd tube wall 23 and size is wider.On the first tube wall 21, offer the opening 25 in order to battery is put into main body tube 2 inner chambers, four tube wall 24 relative with opening 25 caves inward and forms a groove 241, and the cell wall of groove 241 is preferably curved.
Reinforced tube 4 is embedded groove 241 places at main body tube 2, it can be completely in groove, also can half not in groove 241, process opening and the strength problem that brings for reinforcement main body tube 2, the inside of reinforced tube 4 can be used as battery-driven car wiring simultaneously, to form hidden cabling, make car load more attractive in appearance, succinct.The cross section of reinforced tube 4 is also curved, with the shape of groove 241 cell walls of coupling circular arc, reinforced tube 4 and the 4th tube wall 24 of main body tube 2 are fitted, thereby improve on the one hand the bulk strength of frame tube, also prevent from the other hand saving bit by bit rainwater in the gap of the two and corrode tube wall.The length direction of reinforced tube 4 is preferably consistent with the length direction of main body tube 2, and one end of autonomous agent pipe 2 length directions extends to the other end of main body tube 2 length directions always.
In order to ensure the intensity of frame tube, the inner width size L1 of reinforced tube 4 is preferably the 30%-80% of main body tube 2 inner width L2.
The frame tube of the present embodiment can be iron pipe material, it is in the time of moulding, and need are first distinguished moulding to main body tube 2 and reinforced tube 4, then by the main body tube after moulding 2 and reinforced tube 4 weld togethers, as shown in Figure 3, number in the figure 41 positions are the weld nugget of supervisor 2 and reinforced tube 4.Consider requirement attractive in appearance, weld nugget is preferably selected position more hidden and convenient welding, and as in the present embodiment, weld nugget 41 is positioned at the slightly inner position of groove 241 openings.
Above-described embodiment is preferred embodiment of the present utility model, in the specific implementation, also can do suitable distortion, as: in order further to improve the intensity of frame tube, the quantity of reinforced tube 4,4a, 4b can be designed to more than two or two, many reinforced tubes can be welded in groove 241 side by side.In order to adapt to difform main body tube 2, reinforced tube also can not be arranged on the position that opening 25 is relative, as: be arranged on the second tube wall 22 or the 3rd tube wall 23, certainly in order to meet strength demand, reinforced tube preferably should be arranged on the non-aperture position of main body tube tube wall.For main body tube 2 profiles of coupling given shape, that reinforced tube also can be designed to is square, prismatic or triangle etc.
To sum up, the utility model, by reinforced tube is set on frame tube, has made up the strength problem that frame tube brings because offering battery opening, and the inside of reinforced tube also can be used for battery-driven car wiring simultaneously, forms concealed cabling, makes car load more attractive in appearance, succinct.
These are only better possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content have been done changes, and is all included in protection domain of the present utility model.
