Abstract

The utility model discloses an automatic awning which comprises curtain cloth, a motor and a control circuit, wherein the output end of the motor is connected with a rotating shaft, and the upper end of the curtain cloth is attached to the rotating shaft. The left end and the right end of the rotating shaft are respectively provided with a track. The upper end and the lower end of one of the tracks are respectively provided with a dry-reed pipe switch. One side of the lower end of the curtain cloth corresponding to the dry-reed switch is provided with a magnet. A sensor is arranged outside the awning, and the sensor is connected with the control circuit. Because the control circuit controls the awning to open and close, the use is convenient, the failure rate is low, and the sound generated by the impact of rain water is eliminated. In addition, because the curtain cloth can be wound on the rotating shaft at the upper end of a door or a window, the occupation space is little, and the indoor lighting is not affected. An outer cover is sheathed outside the rotating shaft and performs the dust prevention function.

Description

A kind of automatic rain is taken

Technical field

The utility model relates to a kind of window rain insensitive device, and especially a kind of automatic rain is taken.

Background technology

Present employed rain is taken roughly two kinds of structures.A kind of is that fixed rain is taken, and another kind is that opening-closing type rain is taken.Fixed rain is taken and generally is fixedly mounted on the window upper edge, plays sunshade and the effect of taking shelter from rain, but also can influence indoor daylighting sometimes, brings some inconvenience to the user.As long as control link just can make travel(l)ing rest rotate, drive rain and take and open or close when opening-closing type rain is taken and used, can solve the deficiency that fixed rain is taken though the rain of this kind structure is taken, very hard during folding, time one length is easy to generate fault.

The utility model content

The automatic rain that this reality has novel purpose to provide a kind of novel structure, folding with convenience, working life length is taken.

The technical solution of the utility model is: a kind of automatic rain is taken, comprise cord, motor and control circuit, output at motor is associated with a rotating shaft, the upper end of cord invests in the rotating shaft, respectively hung track at the left and right two ends of rotating shaft, the upper and lower end of a track respectively is equipped with a dry-reed tube switch therein, the lower end of cord with the corresponding side of dry-reed tube switch is housed a magnetic patch is housed, one sensor is housed outside rain is taken, and sensor links to each other with control circuit.

In the package of the lower end of cord one suspension rod is arranged.

Suit one outer cover laterally has a crack in the outer cover lower end outside rotating shaft.

Owing to adopt control circuit to control the folding that rain is taken, the sound that use easily, fault rate is very low, sends in the time of also can eliminating the rainwater impact.Because cord can twist in the rotating shaft of door and window upper end, taking up room can not influence indoor daylighting for a short time yet in addition.Suit one outer cover can play dustproof effect outside rotating shaft.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the control circuit structural representation.

The specific embodiment

Structure of the present utility model as shown in Figure 1 and Figure 2, comprise cord 3, motor 2 and control circuit 5, output at motor 5 is associated with a rotating shaft, the upper end of cord 3 invests in the rotating shaft, respectively hung

track

6,7 at the left and right two ends of rotating shaft, a dry-reed tube switch K1, K2 respectively be housed at the upper and lower end of track 6, the lower end of cord 3 with the corresponding side of dry-reed tube switch is housed a magnetic patch 4 is housed, one sensor 1 is housed outside rain is taken, and sensor 1 links to each other with control circuit 5.In the package of the lower end of cord 3 the 8 lifting power effects of one suspension rod are arranged.Suit one outer cover 9 laterally has a crack in outer cover 9 lower ends outside rotating shaft, and cord 3 can pass through this crack.

The course of work of the present utility model is: when rainy, rainwater drips on the sensor 1, thereby makes triode Q ₁Triode Q is given in conducting ₂Provide required bias voltage to make triode Q ₂Conducting, the coil 1J adhesive of relay simultaneously, normally open contact 1J ₂Closure, the coil 3J Attraction strap actuation force normally open contact 3J of relay ₁, 3J ₂, 3J ₃Closure, motor 2 starts, and its output shaft rotates volume cord 3 is thereon descended, when arriving certain position instantly, dry-reed tube switch K ₂Be subjected to the effect of cord 3 lower end magnetic patch 4 and disconnect, coil 3J discharges, and motor 2 quits work, and this moment, cord 3 played rainproof effect.After rainwater stops, and the water droplet on the sensor 1 disappears, triode Q ₁No bias voltage and end Q ₂Also end, this moment, coil 1J discharged, normally closed interlock 1J ₁Conducting, contact 3J ₁3J ₂, 3J ₃Discharge contact 2J ₁, 2J ₂, 2J ₃Closed conducting, motor 2 counter-rotatings, cord 3 bottom outs, the magnetic patch 4 owing to cord 3 lower ends when being raised to certain position acts on dry-reed tube switch K ₁Disconnect, coil 2J discharges, and motor 2 stops, and this moment, cord 3 was rolled.

Claims

1, a kind of automatic rain is taken, comprise cord, motor and control circuit, it is characterized in that: the output at motor is associated with a rotating shaft, the upper end of cord invests in the rotating shaft, respectively hung track at the left and right two ends of rotating shaft, the upper and lower end of a track respectively is equipped with a dry-reed tube switch therein, the lower end of cord with the corresponding side of dry-reed tube switch is housed a magnetic patch is housed, one sensor is housed outside rain is taken, and sensor links to each other with control circuit.

2, automatic rain according to claim 1 is taken, and it is characterized in that: in the package of the lower end of cord one suspension rod is arranged.

3, automatic rain according to claim 1 is taken, and it is characterized in that: suit one outer cover outside rotating shaft laterally has a crack in the outer cover lower end.
