Signal receiving module 121 judges whether to receive release signal, namely step S1 is performed, as do not received, then continuing to wait for, as received release signal, then performing step S2, control module of unblanking 122 outputs signal to motor 60, motor 60 is with carry-over bar 68 to move to away from motor 60 direction, and now skewback 69,70 does not dock with two skewbacks outside gripper shoe 56, namely discharges retaining mechanism.
Then, declining starts control module 123 and performs step S3, judges that whether sensor 77 of unblanking is touched.The base 50 of releasing device is less than before decline, the end of tooth bar 68 can not press sensor 77 of unblanking, when motor 60 be with carry-over bar 68 to away from motor 60 direction motion after, the end of tooth bar 68 will press sensor 77 of unblanking, expression skewback 69,70 do not dock with two skewbacks outside gripper shoe 56.Start the signal that module 123 receives sensor 77 output of unblanking if declined, then perform step S4, output signal to motor 26, motor 26 rotates and drives scissors fork elevating mechanism 40,45 to decline, base 50 and cover body 20 are separated, and base 50 moves downward, as shown in figure 12.
Then, decline and stop control module 124 to perform step S5, judge whether to receive contact to earth sensor 75 export signal, as not having, then continue to wait for, the signal that the sensor 75 that contacts to earth as received exports, represent that base 50 drops to road surface, then perform step S6, stop drive motors 26, scissors fork elevating mechanism 40,45 stops 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.
Owing to twice to be pressed when telecar 82 sails out of or sail into base 50 sensor 76 that delivers from godown of displacement race 71 front end, and telecar 82 is also doublely press the sensor 76 that delivers from godown after sailing base 50 into, therefore, the startup control module 125 that rises performs 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, the startup control module 125 that rises performs step S8, drives 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 be 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 to perform step S9, judge that whether the sensor 74 that puts in storage is touched, in this way, perform step S10, stop driving scissors fork elevating mechanism 40,45 to rise.
And, base 50 will press to be positioned at bottom cover body 20 inwall after rising 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, then perform step S12, closed and locked mechanism, namely output signal to motor 60, tooth bar 68 is driven to move near motor 60 direction by motor 60, skewback 69,70 is docked with two skewbacks outside gripper shoe 56, thus base 50 is fixed on cover body 20 times, avoid mobile warning sign 80 to come off in releasing device.
Certainly, in control device 120, state can be set and return module, the current operating state of releasing device is returned to the control circuit of automobile or remote controller, base 50 as releasing device drops to road surface, telecar 82 sails out of base 50, telecar sails base 50 into, base 50 rises and is locked, and facilitates driver to understand the current operating state of releasing device.
Further, base 50 after telecar 82 sails out of base 50, can be packed up by releasing device, namely rises to start control module and judge that the sensor 76 that delivers from godown is pressed after twice continuously, 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, rise and stop control module 126 whether touched without the need to judging the sensor 74 that puts in storage, only after judging that closed sensor 78 is touched, stopping drives scissors fork elevating mechanism 40,45 to rise and drive motors 60 makes retaining mechanism lock.Now, the button 128 in automobile is luminous, can be long bright luminescence, can be also flashing, not sail in releasing device to remind driver or passenger to move warning sign 80.
When mobile warning sign 80 travels to automobile chassis, control base 50 by the button 128 of automobile or remote controller and decline, again base 50 is risen to cover body 20 times after warning sign 80 to be moved sails base 50 into, base 50 is locked at the below of cover body 20 simultaneously.
Further, when the telecar 82 of mobile warning sign 80 is positioned at releasing device, and under the state that is closed of retaining mechanism, control module 120 can control power module and charge to telecar 82.
Like this, under releasing device can be arranged on the chassis of automobile, and mobile warning sign 80 is arranged in releasing device, as long as driver pushes button and 128 sends signal to the controller of releasing device, namely mobile warning sign 80 can be automatically placed on road surface, getting off without the need to driver is placed on road surface by mobile warning sign 80, and the use of mobile warning sign 80 is very convenient.
