The specific embodiment

Following conjunction with figs. is enumerated preferred embodiment, and structure of the present utility model and effect are elaborated.

Please consult Fig. 1 earlier, be the cell apparatus that is used for electric booster bicycle 10 of the utility model one preferred embodiment, include a battery tray 20 and a battery case 30.

Please cooperate and consult Fig. 2, battery tray 20 has a diapire 21, an end wall 22, and two relative sidewalls 23.Diapire 21 is fixed in a vehicle frame pipe 1 of electric booster bicycle; End wall 22 is connected in the front end of diapire 21, and and diapire 21 between form a groove 24; This two sidewall 23 relatively is connected in the rear end of diapire 21, and the medial surface of each sidewall 23 has a guide groove 25 that extends downwards, and guide groove 25 has a linear portion 252 and a semi-circular section 254.

Battery case 30 has a box body 32 and positioning piece 34.The front end of box body 32 has a protuberance 322, and protuberance 322 can be inserted in the groove 24 of battery tray 20; The top of locations 34 is articulated in the rear end of box body 32 by one first pivot 36, a torque spring 38 is installed at the two ends of first pivot 36 respectively, make locations 34 can be subjected to the effect of this two torque spring 38 and permanent direction toward box body 32 pivots, the two sides of the bottom of locations 34 then have the guide block 342 of a semicircle respectively, and guide block 342 can cooperate the semi-circular section 254 of guide groove 25 and be sticked in the semi-circular section 254.

In the time battery case 30 will being assembled in battery tray 20, as shown in Figure 2, at first the guide block 342 of battery case 30 is slipped in the linear portion 252 of guide groove 25 of battery tray 20, and the application of force presses down battery case 30, except allowing the protuberance 322 of box body 32 insert the groove 24 of battery tray 20, allow the guide block 342 of battery case 30 along the linear portion 252 downward slippages of guide groove 25 again, be sticked in the semi-circular section 254 of guide groove 25 up to guide block 342, as shown in Figure 3, the locations 34 of this moment can pivot towards the direction away from box body 32 a little, so just finishes the installation between battery case 30 and the battery tray 20.

When will be when battery tray 20 takes off with battery case 30, it then is application of force pulling box body 32, when the pulling force of bestowing box body 32 overcomes friction force between the semi-circular section 254 of semi-round guide block 342 and guide groove 25, can allow the guide block 342 of battery case 30 leave the guide groove 25 of battery tray 20, then again the protuberance 322 of box body 32 is detached the groove 24 of battery tray 20, battery case 30 can be taken off.

In order to increase the anti-theft effect of battery case 30, cell apparatus 10 of the present utility model also can provide a locking part 40, as shown in Figure 4.Locking part 40 is hubbed at diapire 21 rear ends of battery tray 20 by one second pivot 50, and has a hook part 42 and can collude in the groove 344 that is stuck in locations 34 with hook part 42, makes battery case 30 be fixed in battery tray 20; In addition, a torque spring 52 is installed at the two ends of second pivot 50 respectively, makes locking part 40 can be subjected to the effect of this two torque spring 52 and allows hook part 42 and groove 344 remain on the state that colludes card mutually.

Thus, when lower piezoelectric pond box 30 when the guide block 342 of battery case 30 is sticked in the semi-circular section 254 of guide groove 25, can take advantage of a situation and collude in the groove 344 that is stuck in locations 34 in the hook part 42 of locking part 40, make battery case 30 be fixed in battery tray 20 and can't take off; In the time will taking off battery case 30, then be that rotate a key hole 26 backs that need utilize a key to insert battery tray 20, force locking part 40 deflections and allow hook part 42 break away from the groove 344 of locationss 34, so just can smoothly battery case 30 be taken off.

Comprehensive the above as can be known, cell apparatus of the present utility model by between battery case guide block and the battery tray guide groove engage and battery case protuberance and battery tray groove between be embedded, can obtain good fixed effect when allowing battery case be installed on battery tray and can be easily break away from, to reach the purpose of this utility model really from battery tray.

The constituent components of the utility model described in the foregoing description is casehistory only, is not to be used for limiting scope of the present utility model, and the substituting or change of other equivalent elements also should be the claim scope that the utility model applies for and contain.
