Shown in Fig. 1-7, in this specific embodiment, operating principle is as follows:

Suppose that sun blind all expand into original state, sun blind all draw in and are end-state.In original state, nut 53 is defined as the initial position of nut 53 near sleeve 77.

Original state, operating personnel operate control member 40, control member 40 sends the rolling order to motor 30, motor 30 runnings, because

motor

30 and 22 fixed installations of first gear, second gear 24 and screw rod 51 fixed installations, first gear 22 and second gear, 24 contrary closing, therefore, screw rod 51 rotates, and the two ends of screw rod 51 are separately installed with first shaft coupling 61 and second shaft coupling 63.First shaft coupling 61 drives first torque arm 67 and rotates, and second shaft coupling 63 drives second torque arm 69 and rotates, and first, second torque arm (67,69) drives winder 65 again and rotates, and winder 65 draws sun blind in.At this moment, according to the lead screw transmission principle, nut 53 is to the direction displacement away from sleeve 77.

As Fig. 1 and shown in Figure 6, when sun blind upwards are contracted to the top, blinds 10 topmost is along with the continuation rolling of winder 65, the Actuator Division 7e that sun blind promote handler 73 moves up, because the effect of pivot 71, shift fork 7h moves, limiting section 7c defines the displacement of shift fork 7h, therefore, limiting section 7c drives entire sleeve 77 and moves, and at this moment, the magnet 80 on the substrate 7a is moved, changes of magnetic field excites and is Hall element in the induction pieces 90(present embodiment) send signal to control member 40, control member 40 sends the signal that stops operating to motor 30.Like this, motor 30 stops operating, and forms end-state.Like this, after the sun blind gathering finished, motor 30 can stop operating automatically.At this moment, nut 53 stays in the position of screw rod 51, is defined as the final position of nut 53.

Generally speaking, the length of sun blind is about five meters, when design, the distance of nut 53 from the initial position to the final position should be more more than the needed stroke of sun blind of five meters length of rolling, but for avoiding control member 40 to break down, perhaps motor 30 breaks down, and motor 30 has kept operating condition mistakenly, like this, screw rod 51 continuous runnings, nut 53 is moved to the delivery position of thick section 51a and thin segment 51b gradually, with spring 55 compressions, owing to there is not screw thread, nut 53 can't continue to move to thin segment 51b direction, like this, though screw rod 51 rotates, can not sustain damage.After changing control member 40 or motor 30, motor 30 counter-rotation, nut 53 is to the direction displacement near sleeve 77.

When needs were opened blinds 10, control member 40 sent a signal to motor 30, and motor 30 is towards turning round in the opposite direction with original side, thereby, winder 65 puts down flat rope and the ladder rope of sun blind, and nut 51 is to the direction displacement near sleeve 77, when sun blind put down fully, nut 51 is passed sleeve 77, at this moment, Hall element is experienced changes of magnetic field, and signal is sent to control member 40, control member 40 instruction motors 30 stop operating, and sun blind no longer continue to open downwards.

Electric controller of the present utility model has the following advantages:

(1) generally speaking, the control device that is used for sun blind, often break down owing to motor, thereby need repairing, and in the prior art, motor 30 and parts integral type assembling often, in maintenance, need each parts is disassembled, behind the replacing motor, be assembled into one one by one again, like this, bring very big inconvenience to maintenance.In the utility model, the first groove 1a, 1b (being motor slot 14) are used for accommodating motor 30, and then by capping 12 motor slot 14 is sealed, when needs are changed out of order motor 30, only capping 12 need be taken off, then motor 30 is taken out from motor slot 14, do not needed to dismantle miscellaneous part, very convenient.

Under the normal condition, be full of nitrogen between the hollow blinds layer glass, control device of the present utility model after protecgulum shell 11 and rear lid case 13 combinations, forms a sealed whole by ultrasonic bonding, and as shown in Figure 6, grey color part is the delivery position of sealing.The screens 16 at the motor slot 14 at motor place and Hall element 90 places is sealing fully not, motor one end and the first gear link position are provided with sealing ring 17, the other end of motor is positioned at does not have sealed space, taking-up and installation when motor 30 and Hall element 90, do not influence the part of sealing, therefore, the nitrogen between the layer glass can not revealed.

(2) whether rolling is carried out offset qualification to the top with respect to traditional employing travel switch to adopt Hall element 90 to detect blinds 10, and Hall element has many advantages, and such as sound construction, volume is little, and is in light weight, simplified the injection mo(u)lding of housing.And it is long that Hall element also has the life-span, easy for installation, and power consumption is little, frequency height, advantages such as vibration resistance.

(3) in the utility model, Hall element is positioned between the screens 16, but screens just is provided with at rear lid case 13, does not have screens at protecgulum shell 11, like this, when changing Hall element if desired, earlier motor 30 is taken out, stretch into the side towards screens 16 of motor slot 14 then by finger, gently Hall element 90 is stirred toward the direction of protecgulum shell 11, make Hall element 90 break away from screens, again Hall element 90 is plucked out.Like this, do not influence the sealing of protecgulum shell 11 and rear lid case 13 yet, do not influence the nitrogen environment among protecgulum shell 11 and rear lid case 13 assemblys.

(4) use the lead screw transmission principle, adopt the cooperation of screw rod 51 and nut 53, the reciprocation cycle of sun blind from original state to end-state, nut 53 also remains on shift reciprocately between initial position and the final position, long screw thread is set on the screw rod 51, makes Stroke Control be adapted to the folding and unfolding of various sun blind generally speaking.And in the prior art, often adopting the Stroke Control parts consistent with the length of specific sun blind, versatility is poor, causes the cost of production of control device than higher.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
