Utility model content
The utility model object is to provide a kind of battery of electric vehicle group, it is similar by battery pack being hidden in to the motor appearance of installing to trailing wheel in the front-wheel of bicycle, front and back weight is very nearly the same, make battery-driven car when keeping front and back weight balancing, it is equally light and handy attractive in appearance with bicycle that outward appearance seems; And do not change the body frame structure for automotive of bicycle, improved the safety performance of battery-driven car integral body.
In order to solve existing problem in background technology, it comprises wheel hub ring and wheel hub cover with matching, the inner side of described wheel hub ring and wheel hub cover is outwards recessed goes out a concentric bearing knock hole, in this bearing knock hole, bearing is installed, in described wheel hub ring, be provided with the battery case of pegging graft and coordinating with its gap, this battery case is whole is provided with the cylindrical structural of opening for end face, one end of its opening part is provided with and fastens with it the battery case lid coordinating, in described battery case, be provided with battery pack and corresponding power brick fender, the middle part of described battery case is fixed with location central siphon, in this location central siphon, be provided with axis, the two ends of described axis are connected with the breeches pipe of rack for electric motor car with wheel hub cover and corresponding bearing through wheel hub ring respectively.
The cross section of described location central siphon is at least one in waist shaped hole or square hole.
Described axis is whole pegs graft and coordinates with fix shaft ligament, in near plane its one end, inwardly offer circular hole, the two ends of described axis outwards vertically extend respectively the boss of pegging graft and coordinating with bearing, the other end of this boss outwards vertically extends screw mandrel, described screw mandrel integral body is the tubular structure of hollow, and the plane place of its end one side inwardly offers notch.
Owing to having adopted above technical scheme, the utlity model has following beneficial effect: similar by battery pack being hidden in to the motor appearance of installing to trailing wheel in the front-wheel of bicycle, front and back weight is very nearly the same, make battery-driven car when keeping front and back weight balancing, it is equally light and handy attractive in appearance with bicycle that outward appearance seems; And do not change the body frame structure for automotive of bicycle, improved the safety performance of battery-driven car integral body; And when maintenance, only tire need be unloaded, facilitate greatly daily maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of axis in the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, the accompanying drawing below in conjunction with in the utility model embodiment, is clearly and completely described the technical scheme in the utility model embodiment.
Referring to Fig. 1-2, this specific embodiment is to be achieved by the following technical solutions, it comprises wheel hub ring 1 and wheel hub cover with matching 2, the inner side of described wheel hub ring 1 and wheel hub cover 2 is outwards recessed goes out a concentric bearing knock hole, in this bearing knock hole, bearing 8 is installed, in described wheel hub ring 1, be provided with the battery case 3 of pegging graft and coordinating with its gap, this battery case 3 is whole is provided with the cylindrical structural of opening for end face, one end of its opening part is provided with and fastens with it the battery case lid 4 coordinating, in described battery case 3, be provided with battery pack 6 and corresponding power brick fender 5, the middle part of described battery case 3 is fixed with location central siphon 7, in this location central siphon 7, be provided with axis 9, the two ends of described axis 9 are connected with the breeches pipe of rack for electric motor car with wheel hub cover 2 and corresponding bearing 8 through wheel hub ring 1 respectively.
The cross section of described location central siphon 7 is at least one in waist shaped hole or square hole.
Described axis 9 is whole pegs graft and coordinates with central siphon 7 gaps, location, in near plane its one end, inwardly offer circular hole 91, the two ends of described axis 9 outwards vertically extend respectively the boss 92 of pegging graft and coordinating with bearing 8, the other end of this boss 92 outwards vertically extends screw mandrel 93, described screw mandrel 93 integral body are the tubular structure of hollow, and the plane place of its end one side inwardly offers notch 94.
Below in conjunction with accompanying drawing, the principle of work of technical scheme in this concrete enforcement is further elaborated:
The screw mandrel 93 at axis 9 two ends is fixed between the breeches pipe of rack for electric motor car, owing to locating the cross section of central siphon 7, be at least one in waist shaped hole or square hole, and axis 9 and location central siphon 7 coordinate for gap grafting, wheel hub ring 1 is connected with the boss 92 at axis 9 two ends by bearing 8 with corresponding wheel hub cover 2 simultaneously, when having guaranteed that wheel hub ring 1 and corresponding wheel hub cover 2 are rotating, keep the stable of battery case 3, be convenient to wiring.
Owing to having adopted above technical scheme, this specific embodiment has following beneficial effect: similar by battery pack being hidden in to the motor appearance of installing to trailing wheel in the front-wheel of bicycle, front and back weight is very nearly the same, make battery-driven car when keeping front and back weight balancing, it is equally light and handy attractive in appearance with bicycle that outward appearance seems; And do not change the body frame structure for automotive of bicycle, improved the safety performance of battery-driven car integral body; And when maintenance, only tire need be unloaded, facilitate greatly daily maintenance.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
