Description
Technical field
The utility model belongs to Electrical Bicycle component technology field, relates in particular to a kind of electro-tricycle frame.
Background technology
The vehicle frame of electro-tricycle is as the skeleton of whole vehicle, and the quality of its structure has directly determined the structural strength of car load, and the complexity of its structure has directly determined the efficiency of production and processing.Electro-tricycle frame generally comprises upper frame and lower frame, and the front end of upper frame is connected with the rear end of lower frame is affixed, and upper frame is used for installing wagon box, and the front portion of lower frame forms places vehicle seat and the accommodating space that drives personnel foot.In prior art, upper frame and lower frame are general adopts a plurality of vertical pipe links to be fixedly connected with, and upper end and the upper frame of pipe link is welded and fixed, lower end and lower frame are welded and fixed.The electro-tricycle frame of said structure comprises the more position that is welded to connect, and causes manufacturing procedure complicated.Meanwhile, a plurality of positions that are welded to connect in actual use owing to jolting, the factor such as vibration and more easily occur that structural strength reduces problem,
Utility model content
The utility model provides for solving the technical matters existing in known technology the electro-tricycle frame that a kind of structural strength is large, simplify manufacturing procedure.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of electro-tricycle frame comprises upper frame and lower frame; Described lower frame is for adopting the same U-shaped shape that metal pipe material bending forming obtains, and its two ends are all upwards bent to form kink, and the top of described kink and upper frame welding are affixed; Between the inner of upper frame and lower frame, be provided with a plurality of front support vertical rods, the two ends up and down of front support vertical rod are affixed with upper frame and lower frame welding respectively; Also comprise crossbeam and one bending forming in its outer end, top is provided with the cant beam of front standpipe, between crossbeam and the front end of upper frame, is provided with front support vertical rod, is provided with reinforcement cross bar between crossbeam and lower frame.
Advantage of the present utility model and good effect are: the utility model provides a kind of electro-tricycle frame of new structure, the U-shaped shape obtaining by lower frame being designed to same metal pipe material bending forming, and kink the welding of the top of kink and upper frame is affixed is set in end, replaced in prior art for upper frame and the vertical pipe link of affixed at least one group of lower frame.Owing to being integrated formed structure, saved the welding processing that originally occurs in this kink position, simplified manufacturing procedure.Meanwhile, due to the minimizing of weld, in the process of car load running, just there is position still less that the accidents such as loosening, sealing-off occur jolting, under the effect of the factor such as vibration, directly promoted the overall construction intensity of vehicle frame.
Preferably: described upper frame comprises the main cross bar that is positioned at both sides, three connection cross bars before, during and after being provided with successively between main cross bar.
Preferably: between the connection cross bar at middle part and the rear end of crossbeam, be provided with rear support vertical rod, the two ends up and down of this rear support vertical rod respectively be connected cross bar and beam welding is affixed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, front standpipe; 2, cant beam; 3, lower frame; 4, front support vertical rod; 5, strengthen cross bar; 6, crossbeam; 7, upper frame; 8, rear support vertical rod; 9, kink; 10, main cross bar; 11, connect cross bar.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises upper frame 7 and lower frame 3, and upper frame 7 is for wagon box and accessory structure are installed, and the front portion of lower frame 3 forms places vehicle seat and the accommodating space that drives personnel foot.
Lower frame 3 is for adopting the same U-shaped shape that metal pipe material bending forming obtains, and its two ends are all upwards bent to form kink 9, and the top of this kink 9 and upper frame 7 welding are affixed.
Between the inner of upper frame 7 and lower frame 3, be provided with a plurality of front support vertical rods 4, the two ends up and down of front support vertical rod 4 are affixed with upper frame 7 and lower frame 3 welding respectively.
Also comprise crossbeam 6 and one bending forming in its outer end, top is provided with the cant beam 2 of front standpipe 1, between crossbeam 6 and the front end of upper frame 7, is provided with front support vertical rod 4, between crossbeam 6 and lower frame 3, be provided with and strengthen cross bar 5.
In the present embodiment, upper frame 7 comprises the main cross bar 10 that is positioned at both sides, and three connection cross bars 11 before, during and after being provided with successively between main cross bar 10 form " day " character form structure.Between the connection cross bar 11 that above-mentioned a plurality of front support vertical rod 4 is located in front end and lower frame 3 and being connected between cross bar 11 and crossbeam 6 of front end.
For further lift structure intensity, in the present embodiment, between the connection cross bar 11 at middle part and the rear end of crossbeam 6, be provided with rear support vertical rod 8, the two ends up and down of this rear support vertical rod 8 respectively be connected cross bar 11 and crossbeam 6 welds affixed.
