The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
Embodiment 1
As Fig. 1 ~ Fig. 3 shows, the thing blind patch electric booster that hangs in embodiment 1 is mainly comprised of two cover hinge switching mechanisms, transmission mechanism and a power unit, the thing blind patch that hangs in embodiment 1 is a main door-plate 15, and this main door-plate 15 is connected to and is hung on thing blind patch housing 14 by two cover hinge switching mechanisms, described every cover hinge switching mechanism is mainly by main hinge 1, upper rotation seat 2, driven gear 3, driven spindle 4, driving gear 5, active rotating shaft 6, lower rotation swing arm 7 and balancing weight 8 form, main hinge 1 is fixedly mounted on and hangs on thing blind patch housing 14, upper rotation seat 2 is contained on main hinge 1 by driven spindle 4 hinges, main door-plate 15 is fixedly connected on rotation seat 2 on one side, lower rotation swing arm 7 one end are contained on main hinge 1 by active rotating shaft 6 hinges, lower rotation swing arm 7 other ends are installed the balancing weight 8 for the deadweight of balance crane thing blind patch, on described driven spindle 4, driven gear 3 is installed, on described active rotating shaft 6, driving gear 5 is installed, described driving gear 5 is meshed with driven gear 3, make main door-plate 15 identical with the rotational angle of lower rotation swing arm 7, opposite direction, active rotating shaft 6 in described every cover hinge switching mechanism is connected with power unit by transmission mechanism, and power unit drives the forward and reverse rotation of active rotating shaft 6 by transmission mechanism, thereby driving is hung, thing blind patch is opened or closure.
As shown in Fig. 1 ~ Fig. 3, in the utility model embodiment 1, described power unit adopts worm gear reducer motor 13, worm gear reducer motor 13 is arranged in the middle of two cover hinge switching mechanisms, and the output shaft of worm gear reducer motor 13 is synchronizeed connection for transmission by the active rotating shaft 6 in transmission mechanism and two cover hinge switching mechanisms.
Transmission mechanism in embodiment 1 is mainly comprised of axle sleeve 9, reducer 10, shaft coupling 11 and synchronizing shaft 12, described synchronizing shaft 12 middle parts are connected with the hollow output shaft of worm gear reducer motor 13, synchronizing shaft 12 two ends are respectively connected with the input of a reducer 10 by shaft coupling 11 and key, and the output of two reducers 10 is respectively connected with the active rotating shaft 6 shaft extension ends on corresponding end hinge switching mechanism by axle sleeve 9 and key.
In concrete application, hang thing blind patch and be initially in closure state (as shown in Figure 2), when needs are opened while hanging thing blind patch, worm gear reducer motor 13 starts, by synchronizing shaft 12 transmitting torques to reducer 10, reducer 10 drives active rotating shaft 6 to rotate, active rotating shaft 6 makes lower rotation swing arm 7 and balancing weight 8 overturn downwards while rotating on the one hand, by driving gear 5, drive driven gear 3 and driven spindle 4 to rotate on the other hand, thereby make rotation seat 2 and upwards upset of main door-plate 15, when main door-plate 15 upwards turn to vertical position, swing arm and balancing weight 8 also turn to vertical position downwards, now hang thing blind patch and open (as shown in Figure 3) completely.In this process, balancing weight 8 can be conducted oneself with dignity by balance crane thing blind patch, reduces the demand to worm gear reducer motor 13 power.
Embodiment 2
As shown in Figure 4, the structure that embodiment 2 and the difference of embodiment 1 are to hang thing blind patch is different, the thing blind patch that hangs in embodiment 2 is mainly comprised of main door-plate 15 and secondary door-plate 17, main door-plate 15 is fixedly connected on rotation seat 2 on one side, and main door-plate 15 another sides and secondary door-plate 17 are hinged by secondary door hinge 16.
In concrete application, when worm gear reducer motor 13 drives main door-plate 15 upwards to overturn by transmission mechanism and hinge switching mechanism, main door-plate 15 drives secondary door-plate 17 to close up by secondary door hinge 16 and folds, when main door-plate 15 upwards turn to vertical position, swing arm and balancing weight 8 also turn to vertical position downwards, now main door-plate 15 folds completely with secondary door-plate 17, hangs thing blind patch and opens (as shown in Figure 4) completely.
