Signal receiving module 121 judges whether to receive release signal, perform step S1, as do not received, continue to wait for, as receive release signal, perform step S2, the control module of unblanking 122 is to motor 60 output signals, motor 60 band carry-over bars 68 are to moving away from motor 60 directions, and now skewback 69,70 does not dock with two skewbacks in gripper shoe 56 outsides, namely discharges retaining mechanism.
Then, decline and start control module 123 execution step S3, judge that whether the sensor 77 of unblanking is touched.Before the base 50 of releasing device does not decline, the end of tooth bar 68 can not press the sensor 77 of unblanking, when motor 60 band carry-over bars 68 are to after away from motor 60 directions motions, the end of tooth bar 68 will press the sensor 77 of unblanking, and expression skewback 69,70 does not dock with two skewbacks in gripper shoe 56 outsides.If declined, start module 123 and receive the signal of unblanking sensor 77 outputs, perform step S4, to motor 26 output signals, motor 26 rotates and drives scissors fork elevating mechanism 40,45 to decline, base 50 is separated with cover body 20, and base 50 moves downward, as shown in figure 12.
Then, decline and stop control module 124 execution step S5, judge whether to receive the signal of sensor 75 output of contacting to earth, as do not have, continue to wait for the signal of sensor 75 outputs of contacting to earth as received, represent that base 50 drops to road surface, perform step S6, stop drive motors 26， scissors fork elevating mechanism 40,45 and stop declining.Now, scissors fork elevating mechanism 40,45 is fully expanded substantially, and base 50 drops on road surface, as shown in figure 13.Now, the telecar 82 of mobile releasing device can sail out of base 50.
When sailing out of or sailing base 50 into due to telecar 82, the sensor 76 that delivers from godown of displacement race 71 front ends will be pressed for twice, and telecar 82 is also the double sensor 76 that delivers from godown that presses after sailing base 50 into, therefore, rise and start control module 125 execution step S7, judge whether the sensor 76 that delivers from godown is pressed for twice continuously, in this way, represent that telecar 82 sails out of base 50 or sails base 50 into, rise and start control module 125 execution step S8, drive scissors fork elevating mechanism 40,45 to rise.
As telecar 82 sails base 50 into, after base 50 rises, the tire 83 of telecar 82 will press the sensor 74 that puts in storage being positioned under wheel folder 73, and the sensor 74 that puts in storage is to controller output signal.Therefore, rise and stop control module 126 execution step S9, judge that whether the sensor 74 that puts in storage is touched, in this way, execution step S10, stops driving scissors fork elevating mechanism 40,45 to rise.
And, base 50 will press after rising to be positioned at bottom cover body 20 inwalls and be provided with closed sensor 78, therefore lock-in control module 127 performs step S11, judge that whether closed sensor 78 is touched, in this way, perform step S12, closed and locked mechanism, to motor 60 output signals, by motor 60, drive tooth bar 68 to moving near motor 60 directions, skewback 69,70 is docked with two skewbacks in gripper shoe 56 outsides, thereby base 50 is fixed on to cover body 20 times, avoid mobile warning sign 80 to come off in releasing device.
Certainly, the interior state that can arrange of control device 120 returns to module, the work at present state that returns to releasing device to control circuit or the remote controller of automobile, as dropping to road surface, telecar 82, the base 50 of releasing device sails out of that base 50, telecar sail base 50 into, base 50 rises and be locked etc., facilitates driver to understand the work at present state of releasing device.
And releasing device can sail out of after base 50 at telecar 82, base 50 is packed up, rise to start the control module judgement sensor 76 that delivers from godown and pressed continuously after twice, be i.e. drive motors 26 drive scissors fork elevating mechanism 40,45 to rise.Because telecar 82 does not sail base into, therefore the sensor 74 that puts in storage is not touched, whether rising, it is touched without the judgement sensor 74 that puts in storage to stop control module 126, only, after judgement closed sensor 78 is touched, stop driving 40,45 risings of scissors fork elevating mechanism drive motors 60 to make retaining mechanism locking.Now, the button 128 in automobile is luminous, can be long bright luminous, can be also flashing, to remind driver or passenger to move warning sign 80, does not sail in releasing device.
