Description
Technical Field
The utility model relates to an electronic solar protection devices, more specifically the theory that says so relates to an electronic built-in solar protection devices of double stroke.
Background
The hollow glass built-in shutter door and window is formed by combining double-layer toughened glass and a sun-shading curtain. The curtain sheet built in the double-layer glass can be manually controlled and can also be remotely controlled by a built-in motor. The light entering the room can be controlled by adjusting the angle of the blind sheet, and the shutter is an ideal product for solving the problem of sun shading. The hollow glass built-in shutter door and window saves the use space, has the functions of heat preservation and noise prevention, and simultaneously gives novel vision to buildings and rooms. In summer or winter, the effect of shading or lighting can be achieved by adjusting the angle of the louver, so that the energy consumption of the air conditioner is greatly reduced. According to the measurement and calculation, when the shutter is in the closed state, the indoor energy-saving effect can be reduced by 40 percent at most.
The electric sunshade curtain in the hollow glass is designed, an electric product is not easy to maintain after the hollow glass breaks down, the maintenance cost is high, and only the hollow glass is opened and the original broken device is replaced, so that the electric product needs to be returned to a factory to be manufactured and sealed again. Time and labor are wasted and money is wasted; in the electric sun-shading device in-service use process, the main point of breaking down, and difficult discovery is driving motor and travel switch device, and between these two, the biggest trouble risk is travel switch device, and the condition of the outage that can not be timely accurate when travel switch device can cause driving motor to damage again.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a fault rate is low, and easy maintenance's electronic built-in solar protection devices of double stroke.
The technical scheme is as follows: the utility model provides an electronic built-in solar protection devices of double-stroke, includes the sealed cavity glass of adopting space bar and sealed gluey connection, be equipped with sunshade screen and mechanism frame in the cavity glass, be equipped with driving motor and transmission shaft in the mechanism frame, be equipped with serving device, working stroke device and reserve stroke device on the transmission shaft, serving device passes through the transmission shaft and is connected with driving motor, after driving motor, working stroke device and reserve stroke device pass through the connecting wire series connection, inserts DC power supply again.
Furthermore, the working stroke of the working stroke device is smaller than that of the standby stroke device, the working stroke device is disconnected, the standby stroke switch is not disconnected at the moment, and the driving motor stops running.
Furthermore, connecting wires of the driving motor, the working stroke device and the standby stroke device are arranged on the outer side of the hollow glass, so that even if one stroke switch is burnt out and broken, the broken stroke switch can be directly tripped out in field maintenance without disassembling the glass, and the maintenance is time-saving, labor-saving and money-saving.
Furthermore, the working stroke device is set as a standby stroke device, the standby stroke device is set as a working stroke device, and the working stroke of the working stroke device is smaller than that of the standby stroke device.
Furthermore, the working stroke device comprises a stroke switch, the stroke switch comprises a gear shaft and at least two screws which are arranged in parallel, each screw is provided with a nut which is assembled with the screw thread of the screw, the outer surface of the nut is a gear which is meshed with the gear shaft, one tail end of each screw is provided with a contact, and the tail end contact directions of the two screws are opposite; the spare stroke device is the same as the working stroke device in structural arrangement.
Further, the sunshade curtain is one of a blind curtain, a honeycomb curtain, a pleated curtain and a cloth curtain, and can be selected according to different application places.
Principle of operation
The electric sunshade device is characterized in that two travel switches are connected with a driving motor in series, wherein the position distances of travel points at two ends of a working travel switch are smaller than those of a standby travel switch.
When the current of the direct current power supply passes through the driving motor, passes through the working travel switch and then passes through the standby travel switch to return to the direct current power supply, the driving motor starts to operate, the sunshade screen is unfolded (folded) to start to operate, when the sunshade screen reaches the top (bottom), the working travel switch is disconnected, the standby travel switch at the moment can be disconnected, and the driving motor stops operating.
When the working travel switch has a fault, the working travel switch cannot work normally and cannot cut off the current in time, the standby travel switch works to cut off the current in time, and the driving motor can still normally stop running.
Has the advantages that: the utility model relates to a double-stroke electric built-in sunshade device, which adopts two stroke switches, thereby obviously improving the reliability of the electric sunshade device and simultaneously reducing the possibility that a motor is burnt out by locked rotor; in addition, the wires of the original devices of each electrical appliance are connected outside the hollow glass, so that even if one travel switch is burnt out and broken, the travel switch can be maintained on site without disassembling the glass, and the damaged travel switch can be directly tripped off, so that the maintenance is time-saving, labor-saving and money-saving.

Detailed Description
For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples.
Example 1
The utility model discloses a two-stroke electric built-in solar protection device, including adopting space bar and sealed hollow glass of sealed connection of fluid sealant, be equipped with sunshade screen 203 and mechanism frame 202 in the hollow glass, be equipped with driving motor 101 and transmission shaft 104 in the mechanism frame 202, be equipped with ropewinder 102, working stroke device 102 and reserve stroke device 103 on the transmission shaft 104, ropewinder is connected with driving motor through the transmission shaft for the rising and the decline of control sunshade screen; the working stroke device comprises a stroke switch, the stroke switch comprises a gear shaft and at least two screws (which are used for respectively controlling the unfolding and folding of the sunshade curtain) which are arranged in parallel, each screw is provided with a nut and is assembled with the screw thread of the screw, the outer surface of the nut is a gear meshed with the gear shaft, one tail end of each screw is provided with a contact, and the tail end contacts of the two screws are opposite in direction; the structure of the spare stroke device is the same as that of the working stroke device, one of the spare stroke device and the working stroke device can be selected as a working stroke switch, and the other spare stroke device is selected as a spare stroke switch; after the driving motor, the working stroke device and the standby stroke device are connected in series, a direct current power supply 401 (the direct current power supply is controlled by a switch) is connected, wherein a connecting wire 301 of the driving motor, the working stroke device and the standby stroke device is arranged on the outer side of the hollow glass; the distance between the positions of the travel points at the two ends of the working travel switch is smaller than the distance between the standby travel switches.
