Embodiment

Shown in Fig. 1,2,4, the utility model comprises: lock opens judging part 2 and lock opens control part 3, and lock opens on the battery tray 4 that judging part 2 is arranged on battery handler 1, and lock opens on the battery case 5 that control part 3 is arranged on the placement battery case 14 that is installed in the electric motor car; When battery tray 4 during near battery case 14, if battery case 14 is positioned at battery case 5, lock opens judging part 2 and opens the electromagnetic lock 6 that control part 3 will be arranged on the battery case 5 by lock and open, otherwise lock opens control part 3 control electromagnetic locks 6 and is in closed condition.

Specifically shown in Fig. 2,3,4, lock opens judging part 2 and comprises: connecting rod 21, rotating shaft 23, push rod 22, jam plate 24 and torsion spring 25, jam plate 24 rotatable battery tray 4 front ends that are arranged on, one end of connecting rod 21 is installed on the battery tray 4 by rotating shaft 23, and can drive rotating shaft 23 and rotate at certain angle, in the one end fixed installation rotating shaft 23 of push rod 22, the other end of push rod 22 withstands on the pin plate 24.Drive rotating shaft 23 rotations when connecting rod 21 rotations, push rod 22 also pivots at certain angle.The other end of push rod 22 withstands on the pin plate 24, and when connecting rod 22 was not depressed, push rod 22 withstood jam plate 24.When connecting rod 22 was depressed, push rod 22 rotated to certain angle, thereby jam plate 24 is opened.

Lock opens control part 3 and comprises: stage clip 32 and bearing pin 31, bearing pin 31 is installed on the underframe of battery case 5, and lock to open judging part 2 corresponding, stage clip 32 is sleeved on the bearing pin 31.Bearing pin 31 can move in battery case 5 under the effect of external force, and resets under the elastic acting force of stage clip 32 when also external force is cancelled.When bearing pin 31 was stretched in battery case 5, bearing pin 31 can trigger and be arranged on being used on the battery case 5 and control the control switch 7 of electromagnetic lock 6, thereby electromagnetic lock 6 is opened, and promptly the tapered end 8 of electromagnetic lock 6 is withdrawn in the electromagnetic lock 6.When bearing pin 31 resetted under the effect of stage clip 32, electromagnetic lock 6 cut out, and promptly tapered end 8 stretches out from electromagnetic lock 6.Electromagnetic lock 6 is under closing state, and tapered end 8 is in the state that elasticity is stretched out electromagnetic lock 6.If, tapered end 8 can be pushed back in the electromagnetic lock 6 to this moment tapered end 8 being applied towards the power of electromagnetic lock 6.

Therefore, when getting battery case 14, battery tray 4 is near battery case 5 (promptly near the battery case 14 that is placed in the battery case 5), withstand jam plate 24 owing to push rod 22 this moment, this moment jam plate 24 to push down bearing pin 31 mobile to battery case 5 in, when touching control switch 7, electromagnetic lock 6 to be opened, tapered end 8 is withdrawn in the electromagnetic lock 6.Like this, just can battery case 14 be taken out by the battery suction means that is arranged on the battery tray 4.When battery case 14 moved on the battery tray 4, because battery case 14 is depressed connecting rod 21, connecting rod 21 rotated, and drove rotating shaft 23 rotations, and rotating shaft 23 drives push rod 22 rotations again.Push rod 22 rotates to certain angle and just no longer heads on jam plate 24, thereby bearing pin 31 is after under the effect of stage clip 32 backing down jam plate 24, and the electromagnetic lock 6 on the elastic reset, this moment battery case 5 just has been in blocking.When preparation was pushed into battery case 5 with battery case 14, because battery case 14 is pressed on the pull bar 21, this moment, jam plate 24 was in the state that is not withstood by push rod 22.When battery tray 4 once more when the battery case 5, the position that bearing pin 31 just can not pushed up control switch 7 by pin plate 24, just saying that electromagnetic lock 6 is in blocking all the time when preparing to push battery case 14, inclined-plane compression tapered end 8 by the block on the battery case 14 20, behind the peak process tapered end 8 of block 20, tapered end 8 ejects, thereby battery case 14 is locked in the battery case 5, as shown in Figure 5 firmly.

Simplified the structure of by communication modes electromagnetic lock 6 being controlled in the past greatly by said structure, not only structure is simpler, and easier operation, is not easy to break down.

In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection range of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
