Abstract

The utility model relates to an automatic electronic awning, comprising awning cloth, a movable frame, and a rope. The rope is connected with a bidirectional motor. The motor is controlled by a circuit. The utility model can automatically spread out the awning when light or rain exists according to the variation of weather so long as a switch of the motor is dialed to a positive rotating gear in advance. When the awning is contracted, the motor can be reversed immediately to contract the utility model so long as the switch of the motor is dialed to a negative rotating gear. The utility model omits the troublesome operation of rope pulling, rope drawing, rope unbinding, etc.

Description

The automatic positive rain cover of electronics

But the utility model relates to a kind of automatic positive rain cover of positive rain cover, particularly electronics of the retractable of being made up of paulin and movable frame.

At present, the door and window of buildings such as many dwelling houses, commercial and residential building and along the street the shop front etc. positive rain cover has been installed, this positive rain cover is made up of paulin and movable frame, but by the rope retractable.Receive the rope that to stretch when fluffy, need end is led the jail after paulin draws in, avoid getting loose.Put and separate rope again when fluffy, put rope, very bothersome, and draw, put rope and all want fenestration procedure, for the more apparent trouble in the room that is provided with air-conditioning.

The purpose of this utility model provides the automatic positive rain cover of a kind of electronics, and it can avoid the trouble of manual folding and unfolding paulin, and can also put fluffy automatically according to Changes in weather.

The automatic positive rain cover of the utility model electronics comprises paulin, movable frame and rope, rope links to each other with an either-rotation motor, either-rotation motor is controlled by circuit, said circuit connecting relation is as follows: power supply E is by transformer B step-down, the inferior coil of transformer B links to each other with two inputs of rectifier D1-1, be connected in series microswitch constant close contact K1 between the base stage of transistor BG1 and the colelctor electrode, resistance R 1, water-sensitive K switch 2, light resistor R2 and hand switch K are parallel to two ends of K2 respectively, the R2 hand switch K4 that connects, the colelctor electrode of BG1, one end of relay J 1 and the negative pole of a diode D2 while output with rectifier D1-4 links, the anode of the other end of relay J 1 and diode D2 links with the colelctor electrode with transistor BG2, the base stage of GB2 and the emitter stage of BG1 link, the emitter stage of BG2 connects another output of rectifier D1-4, connect capacitor C between two outputs of D1-4, relay J 2 and constant open contact J1-1 are serially connected with two ends of power supply E, either-rotation motor M is connected to two ends of power supply E by shift switch M, K3 contains forward contact a, d and counter-contact b, c can shift gears by button.

This positive rain cover meets solar radiation or when rainy, its light resistor R2 or water-sensitive K switch 2 can be connected control circuit automatically, motor promptly get electric be rotated in the forward put fluffy, until putting fluffy finishing, movable frame is run into microswitch, and constant close contact K1 disconnects, down circuitry, the left alone without help commentaries on classics of motor M.When needs are received when fluffy, only need press the K3 button and be allocated to b, c retaining, motor promptly reverse receive fluffy.

In sum, the utility model sun rain cover only needs in advance motor switch to be dialled to just changeing retaining, and it can be met illumination or meet rain and put fluffy automatically according to Changes in weather.Receiving only needs when fluffy motor switch is allocated to the counter-rotating retaining, motor reverse immediately receive fluffy.Remove troublesome operation such as stay cord, lead, Xie Sheng from.Switch control casket can be contained in indoor, stirs button and need not the open and close window, and is very convenient.

Below in conjunction with description of drawings structure of the present utility model and operating principle.

Fig. 1 is the circuit theory diagrams of the automatic positive rain cover of this electronics, and Fig. 2 is a microswitch installation site schematic diagram.

Among Fig. 1, microswitch K1 is a constant close contact, is closure state when promptly not stressing, and just disconnects behind the pressurized.It can be contained in the position (as Fig. 2) that can run into it after movable frame opens fully, and among Fig. 2, movable frame 1 is opening downwards, and when it opens when putting in place fully, framework 1 will be collided with microswitch 2, make the switch spring pressurized, and contact K1 disconnects.Therefore, under the occasion that paulin draws in, K1 is closed, and after paulin put down, K1 disconnected.Motor M among Fig. 1 is an either-rotation motor, and it can change by shift switch K3 and turns to.The a of K switch 3, d are the forward contact, and b, c are counter-contact, can shift gears by button.Light resistor R2 is closed under certain illumination, and water-sensitive K switch 2 is met the water closure, and they all can be contained in this positive rain cover top or other is in the position that is subject to light, is subjected to rain.K is a manual switch.When needing automatic control, in advance K is pushed the position of disconnection, K3 is pushed a, d retaining.R2 or K2 closure when illumination reaches certain intensity or has rainwater to fall, control circuit is connected the 12V electric current, relay J 1 triggers the J1-1 closure, relay J 2 energisings, J2-1 closure, the logical 220V electric current of motor M and be rotated in the forward and put rope, paulin opens, and when movable frame was run into microswitch, K1 disconnected, J1-1 and J1-2 also disconnect thereupon, the left alone without help commentaries on classics of motor M.When needing receipts fluffy, K3 is allocated to b, c retaining, motor directly meets power supply E and the serving that reverses, and is that K3 dials back a, d retaining, the left alone without help commentaries on classics of motor after paulin draws in.Among Fig. 1 embodiment, the R2 hand switch K4 that connects has sunlight when winter and does not need to put when fluffy, K4 can be disconnected.Unglazed no rain is intended putting fluffy occasion, can closed manual switch K, can put fluffy.If K3 is pushed neutral gear position, then motor can not be switched on, and can make this awning keep original state constant.

Among Fig. 1, B1 is fuse.
