Description

Electrical Bicycle removable jew power supply box and configuration thereof

The utility model relates to technical field of bicycles, specifically Electrical Bicycle removable jew power supply box and configuration thereof.

The driven formula power supply box of existing Electrical Bicycle is installed on the clothes hanger of bicycle mostly, and it is bad to make that clothes hanger can not use with vehicle's center of gravity, and the result of use and the car load that have influenced Electrical Bicycle are attractive in appearance.

The purpose of this utility model provides a kind of simple in structure, compact, the Electrical Bicycle removable jew power supply box and configuration thereof of being convenient to install Electric booster.

The technical solution of the utility model is: between the transverse oblique beam of vehicle frame power supply box is housed, power supply box is fixed on the vehicle frame by connector.The garden arc breach of battery box afterbody blocks vehicle frame saddle standpipe bottom; Two pivot pins of battery box head are stuck in two oblique beam corresponding apertures of vehicle frame, and power supply box is fixed.

The utility model is described in further detail below in conjunction with accompanying drawing, but be not limited to shown in the accompanying drawing.

Fig. 1 is the utility model 1 type structural representation

Fig. 2 is the utility model 2 type structural representations

Fig. 3, Fig. 4 are the utility model vehicle frame partial enlarged drawing

Fig. 5, Fig. 6, Fig. 7 are the utility model power supply box figure

Fig. 8 is the utility model 1 type integral structure figure

Fig. 9 is the utility model 2 type integral structure figure

Among the figure, the last oblique beam of 1-, oblique beam under the 2-, 3-power supply box, 4-mounting bracket, 5-standpipe, the 6-central siphon, 7-pivot pin, 8-lock core, 9-screw, 10-screw, 11-screw, 12-left side case, the right case of 13-, 14-screw, 15-fuse base, 16-screw, the 17-support, 18-roller, 19-cam, 20-socket, 21-electrode contact, the 22-electric controller, 23-vehicle frame, 24-Electric booster, 25-stretcher 26-bolt, 27-crank throw, the big flying disc of 28-, 29-axis, 30-chain, the electronic hub of 31-, 32-electrode contact seat.

Shown in Fig. 1,2,3,4,5,6,7, the utility model partly is made up of vehicle frame (23) and battery box (3) two.

Vehicle frame 23 is similar with the ordinary bicycle vehicle frame, and energy power supply box 3 is housed between last oblique beam 1 and following oblique beam 2, and electrode contact seat 32 is equipped with in seat tube 5 bottoms.

Power supply box 3 is made of with right case 13 left case 12, is connected as one by

screw

9,10,11,14.The power supply box head is a carrying handle, and parts such as support 17, pivot pin 7, roller 18, lock core 8, cam 19 are installed therebetween.When lock core 8 rotates, drive cam 19 and rotate, cam 19 withstands roller 18, makes with roller 18 bonded assembly pivot pins 7 to move up and down at support 17 upper edge axis, and the top ends of pivot pin 7 can appear the power supply box shell.Cavities partly is used to install storage battery in the power supply box.Power supply box afterbody symmetry up and down has A, two gardens of B arc column shape v notch v, and electrode contact 21 is arranged in the B breach, in the triangular form cavity on A, B breach side fuse base 15 and socket 20 is installed.

When power supply box is installed, earlier afterbody bottom is touched down oblique beam, the A breach is blocked standpipe, head is pushed middle part between oblique beam and the following oblique beam, twist lock core with key, stretch out from the power supply box shell pivot pin end, injects in the upper and lower oblique beam corresponding aperture, and battery box just is fixed and pins between upper and lower oblique beam.Simultaneously, the electrode contact of battery box afterbody also contacts with the electrode contact seat, for power delivery is got ready to motor.

When taking off the source case, the reverse procedure during by installation is carried out.

Be illustrated in figure 1 as 1 type structure of the present utility model, mounting bracket 4 is arranged at following oblique beam 2 bottoms, is used to install Electric booster 24; Fig. 2 is 2 type structures of the present utility model, still remains with central siphon 6, is used to install axis 29 attachments of a bicycle such as grade.

Fig. 8 is 1 type structural entity figure of utility model.It adopts vehicle frame 23 shown in Figure 1, and the Electric booster 24 usefulness bolts 26 of band stretcher 25 are fastened on down on the mounting bracket 4 of oblique beam 2, have formed a complete Electrical Bicycle with parts such as electric controller 22, power supply boxs 3.

Fig. 9 is 2 type structural entity figure of utility model, and it adopts vehicle frame shown in Figure 2, and electronic hub 31 can be installed on trailing wheel or the front-wheel; Central siphon 6 positions are equipped with parts such as axis 29, big flying disc 28, crank throw 27, stretcher 25, chain 30, add that parts such as electric controller 22, power supply box have formed a complete Electrical Bicycle together.

Structure of the present utility model makes power supply box can load onto reliably on vehicle frame and guarantee that anti-theft is good, simultaneously Can take off easily again, have compact conformation rationally, dependable performance, good looking appearance, the characteristics such as practical, The desirable auxiliary products of electric bicycle.
