• a gear device comprising a wheel 750 operable in rotation by a motor 751 and slots 752, meshed with the wheel and arranged on the outer side wall of the bell 74.
• the second actuating means 75 are controlled by the control means C, upon receipt of an electrical control signal.
• Detection means of the end-of-travel sensor type, can be housed in the storage box 71 and arranged to mark the end of the travel of the bell 74 relative to the base 73, at the end of opening or at the end of closing.
• the detection means are configured to send a stop signal to the motor 751 when the bell 74 has reached its end of travel, on opening and on closing.
• the bell 74 can thus carry a finger 740 arranged to cooperate with a first end-of-travel sensor 76 when the bell 74 has reached its end of cover closing travel (FIG. 7B) and to cooperate with a second sensor 77 of end of race when the bell 74 has reached its end of the cover opening race (FIG. 8B).
• the two sensors are fixed to the base 73 and positioned in a suitable manner to cooperate with the finger 740 when the bell reaches its end of travel on opening and its end of travel on closing.
• the lid is closed, sealing the storage box 71 in a sealed manner.
• the lid is open, allowing the cable 8 carrying the plug 2 to descend towards the plate 3.
• the storage box can be fixed directly to the body of the storage unit 6.
• the device 5 can comprise a pipe 70 fixed to the storage unit 6 by a first end, called fixing.
• conduit 70 is connected to the output of reel 61 and is crossed by cable 8.
• conduit 70 has a free end carrying the storage box 71 of sheet 2.
• the duct 70 may have a rigid structure that is little or not deformable. This duct is also adaptable to the second embodiment of the device, described above in connection with FIGS. 6A and 6B.
• the operating sequence of the device produced according to the first embodiment is the next :
• the plate 3 is placed on the ground S and the vehicle V is moved forward to position itself above the plate 3 (FIG. 9A). - The presence of the vehicle V can be detected above the plate 3, by system detection means M1. These detection means M1 send the first electrical control signal S0 to the control means C (FIG. 9B).
• control means C Upon receipt of the first detection signal, the control means C actuates the device of the invention.
• the control means C send a second electrical control signal S1 to control the second actuating means 75, for opening of the lid 72 and a third electrical control signal S2 to control the first mechanical actuating means 62 for to unwind the cable 8 from the winder 61.
• the plug 2 is extracted from the storage box 71 to move towards the tray 3.
• the plug 2 is first guided by the magnetic means integrated into the plate 3 and then attracted by the magnetic means of the socket 2 to be connected thereto (FIG. 9C).
• the control means C are thus configured to execute a cable extraction sequence which comprises:
• the movement is stopped upon receipt of the end-of-travel signal sent by the first sensor 65.
• control means are configured to execute a cable storage sequence which comprises:
• the movement is stopped upon receipt of the end-of-travel signal sent by the second sensor 66.
• the detection means M1 employed can be optional.
• the activation of the device can in fact be carried out manually by a user when the latter knows that the vehicle is well positioned with respect to the platform 3.
• the control unit UC then sends the first electrical control signal S0' to activate the device 5.
• detection means M1 suitable for automatic activation can be of any type.
• it may be a solution of the radar type, RFID sensor or of the mechanical type, for example via at least one chock intended to cooperate with a wheel of the vehicle, said chock carrying a presence sensor capable of emitting the first electrical control signal S0.
• this presence sensor can be a position switch, advantageously operating autonomously in electrical energy, integrating a converter of mechanical energy (caused by the pressure of the vehicle) into electrical energy capable of supplying a radio transmitter configured to output the S0 signal.
• the invention thus has many advantages, including:
• the device 5 can remain permanently in the vehicle V;
