For in background technology, propose based on bicycle structure and be more prone to the deficiency that the Electrical Bicycle of lightweight, simplification design exists its battery set fixing structure to exist, the utility model object is to provide a kind of battery pack mounting structure of battery-driven car, its battery pack mounting structure is compacter and reasonable, can guarantee the stable operation of battery pack simultaneously.
For achieving the above object, the utility model provides following technical scheme: a kind of battery pack mounting structure of battery-driven car, comprises and be connected in the frame tube of vehicle seat lower end and be placed in battery pack in frame tube; It is characterized in that: described battery pack and frame tube are respectively corresponding cylindrical; Described frame tube bottom arranges the cylindrical wire base corresponding with battery pack, described wire base side and frame tube sidewall arrange respectively corresponding positioning groove and positioning screw hole in identical setting height(from bottom), described positioning groove is the annular groove that is positioned at wire base side, passes positioning screw hole and its end be placed in and in positioning groove, realize the fixing of wire base and frame tube by screw; Described battery pack lower end and wire base upper end arrange respectively absorption magnet; Between described vehicle seat and battery pack upper end, pressure elastic fixing device is set.
The utility model is also further set to: described wire base arranges respectively a plurality of concentric ring connection terminals and is positioned at the binding post of its center in its terminal portions; Described battery end arranges corresponding with ring connection terminal and binding post respectively electrode terminal.
The utility model is also further set to: described positioning groove is the arc groove of the multiple stage corresponding with fixing screw.
The utility model is also further set to: described elastic fixing device is Compress Spring.
The utility model is also further set to: described absorption magnet is built in respectively battery pack lower end and wire base upper end.
The beneficial effects of the utility model: the coordinating of positioning groove of passing positioning screw hole and wire base side by screw, realize the axial restraint of wire base in frame tube, the bottom of battery pack and the upper end of wire base arrange respectively the absorption that absorption magnet realizes both and fix, and realize to battery pack the axial restraint in frame tube by the pressure elastic fixing device of battery pack upper end with the combination of absorption magnet simultaneously; When wire base is fixed in frame tube, because its side is the annular groove consistent with fixing screw height, screw can directly pass positioning screw hole, and does not need butted line base to be rotated the adjusting of position, can be so that its assembling; The wire base ring connection structure corresponding with battery pack, can realize both and at battery-driven car, in course of normal operation, realize stable connection simultaneously; In the process of travelling, even in road surface situation compared with under complicated situation, jolting appears in vehicle, battery pack also can be stable be placed in frame tube, there will not be the bad contact of battery pack and wire base, can be due to circut breaking in the process of travelling, make whole battery-driven car occur that equipment restarts; When needs are changed battery pack, can.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figures 1 to 5, a kind of battery pack 4 mounting structures of battery-driven car, comprise and are connected in the frame tube 1 of vehicle seat 2 lower ends and are placed in the interior battery pack 4 of frame tube 1; It is corresponding cylindrical that battery pack 4 and frame tube 1 are respectively; Frame tube 1 bottom arranges the cylindrical wire base 3 corresponding with battery pack 4, wire base 3 sides and frame tube 1 sidewall arrange respectively corresponding positioning groove and positioning screw hole 11 in identical setting height(from bottom), positioning groove is the annular groove 33 that is positioned at wire base 3 sides, in the present embodiment, annular groove 33 is the arc groove of corresponding multiple stage, by screw 12, through positioning screw hole 11 and its end, is placed in and in corresponding arc groove, realizes the fixing of wire base 3 and frame tube 1; Battery pack 4 lower ends and wire base 3 upper ends arrange respectively absorption magnet (omitting in accompanying drawing), and absorption magnet is built in respectively battery pack 4 lower ends and wire base 3 upper ends; Between described vehicle seat 2 and battery pack 4 upper ends, Compress Spring 5 is set.Described wire base 3 arranges respectively a plurality of concentric ring connection terminals 31 and is positioned at the binding post 32 of its center in its terminal portions; Described battery end arranges corresponding with ring connection terminal 31 and binding post 32 respectively electrode terminal 41.
