Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: embodiment cover plate opening and closing drive unit is primarily of drive motors 1 and the two cover reduction gearing mechanisms compositions be attached thereto, described drive motors 1 is two output shaft electric machines, two described cover reduction gearing mechanisms are separately positioned on door panel assemblies both side ends position, drive motors 1 is between two cover reduction gearing mechanisms, and two output shafts of drive motors 1 overlap reduction gearing mechanism respectively by synchronizing shaft 2 and two and are connected.
As shown in Fig. 1 ~ Fig. 5, in the utility model embodiment, described reduction gearing mechanism primarily of reductor 3, initiatively flange shaft 4, flange shaft bearing support 5, drivenly roll fixed head 6, connect arc flange 7, connecting axle bearing sleeve 9, drive sprocket 10, turn to sprocket shaft 11 and turn to sprocket wheel 12, the power shaft of described reductor 3 is connected with the output shaft of drive motors 1, the output shaft of reductor 3 is installed initiatively flange shaft 4, described active flange shaft 4 front end is arranged in flange shaft bearing support 5 by bearing supporting, and flange shaft bearing support 5 is arranged on and drivenly rolls on fixed head 6; Initiatively flange 4a is provided with in the middle part of described active flange shaft 4, the part described active flange shaft 4 being positioned at the blue 4a front of active method is set with and connects arc flange 7, connecting axle bearing sleeve 9 and drive sprocket 10, the neighboring of described connection arc flange 7 is provided with the centrosymmetric arc connecting channel of twice, and described connection arc flange 7 is connected by the slide bolt 8 be contained in arc connecting channel with described active flange 4a; Described drive sprocket 10 is fixedly mounted on initiatively in flange shaft 4, and described connecting axle bearing sleeve 9 is arranged on and connects arc flange 7 between drive sprocket 10, connecting axle bearing sleeve 9 one end be connected arc flange 7 and connect, connecting axle bearing sleeve 9 other end is connected with drive sprocket 10; The described sprocket shaft 11 that turns to is arranged on driven rolling on fixed head 6 by rolling bearing units 13 supporting, turns to sprocket shaft 11 to be positioned at above active flange shaft 4, turns to fixed installation on sprocket shaft 11 to turn to sprocket wheel 12.
Operating principle of the present utility model and the course of work as follows:
Reductor 3 power shaft in reduction gearing mechanisms is overlapped in power transmission by the output shaft at drive motors 1 two ends to two, rotating speed reduces and increases torsion by reductor 3, the positive and negative rotation of tractive chain is driven by the drive sprocket 10 be arranged in active flange shaft 4, tractive chain drives connected door-plate to move again, all door-plates are made all outwards to move and overturn, finally be turned to 90 degree, hang thing hole security protection cover plate and all open.
When hanging the door-plate of thing hole security protection cover plate, when opening, need break the equilibrium state of all folding doors, now conduction chain there will be displacement, this displacement is slided in the arc connecting channel connecting arc flange 7 by slide bolt 8, eliminates the impact on reductor 3 and drive motors 1.
