Example 1
As shown in fig. 1 and 2, a photovoltaic energy-saving single-motor sub-control day and night curtain sequentially comprises a top rod 41, a sub-curtain rod 42 and a bottom rod 43 from top to bottom, wherein a first curtain 11 is arranged between the top rod 41 and the sub-curtain rod 42, the upper end of the first curtain 11 is connected with the top rod 41, the lower end of the first curtain 11 is connected with the sub-curtain rod 42, and the opening degree (i.e. the unfolding degree) of the first curtain 11 is controlled by changing the distance between the top rod 41 and the sub-curtain rod 42. A second curtain 12 is provided between the curtain separating rod 42 and the bottom rod 43, the upper end of the second curtain 12 is connected to the curtain separating rod 42, the lower end of the second curtain 12 is connected to the bottom rod 43, and the opening degree of the second curtain 12 is controlled by changing the distance between the curtain separating rod 42 and the bottom rod 43.
Unlike the existing day and night curtains, the control drive of the day and night curtain is arranged on the curtain separating rod 42, the first rope rolling shaft 201 of the first curtain 11 and the second rope rolling shaft 202 of the second curtain 12 are arranged in the curtain separating rod 42, one end of a first stay rope of the first curtain 11 is fixed on the ejector rod 41, and the other end passes through the first curtain 11 from top to bottom and then is wound on the first rope rolling shaft 201; one end of the second rope of the second curtain 12 is fixed to the bottom rod 43, and the other end passes through the second curtain 12 from bottom to top and is wound around the second rope winding shaft 202.
When the motor 31 drives the first rope winding shaft 201 to rotate and wind the first rope, the first rope is fixed with the ejector rod 41, so that the curtain separating rod 42 gradually rises along with the gradual winding of the first rope, thereby accommodating the first curtain 11; at this time, the second cord of the second curtain 12 is not affected, the distance between the bottom rod 43 and the shade separating rod 42 is not changed, and the opening degree of the second curtain 12 is not changed. Conversely, if the first cord reel 201 rotates and releases the first cord, the shade separating rod 42 gradually descends, thereby lowering the first shade 11.
Similarly, when the motor 31 drives the second rope winding shaft 202 to rotate and wind the second rope, the second rope is fixed to the bottom rod 43, so that the bottom rod 43 gradually rises as the second rope is gradually wound, thereby accommodating the second curtain 12; at this time, the first cord of the first curtain 11 is not affected, the distance between the jack 41 and the curtain separating rod 42 is not changed, and the opening degree of the first curtain 11 is not changed. Conversely, if the second cord reel 202 rotates and releases the second cord, the bottom bar 43 gradually descends, thereby lowering the second curtain 12.
When the motor 31 simultaneously drives the first winding shaft 201 and the second winding shaft 202 to rotate, and the first winding shaft 201 winds up the first pull rope and the second winding shaft 202 releases the second pull rope, the split curtain rod 42 rises, the distance between the ejector rod 41 and the bottom rod 43 is unchanged, the opening ratio of the first curtain 11 is gradually reduced, and the opening ratio of the second curtain 12 is gradually increased as the split curtain rod 42 gradually rises. Conversely, the first winding shaft 201 releases the first pulling rope and the second winding shaft 202 winds the second pulling rope, the split curtain rod 42 descends, the distance between the top rod 41 and the bottom rod 43 is unchanged, the opening ratio of the first curtain 11 gradually increases and the opening ratio of the second curtain 12 gradually decreases as the split curtain rod 42 gradually descends.
When the motor 31 drives the first rope reel 201 and the second rope reel 202 at the same time, the rope winding and unwinding states of the first rope reel 201 and the second rope reel 202 are opposite. In the embodiment, the rotation directions of the first rope winding shaft and the second rope winding shaft are the same when the first rope winding shaft and the second rope winding shaft rotate simultaneously, and the winding direction of the pull rope is arranged, so that the pull rope can be wound when the first rope winding shaft rotates positively, and the pull rope is released when the second rope winding shaft rotates positively; the first rope winding shaft releases the pull rope when rotating reversely, and the second rope winding shaft winds the pull rope when rotating reversely.
In other alternative embodiments, the winding and unwinding states of the first rope reel 201 and the second rope reel 202, which are rotated simultaneously, may be the same by changing the winding direction of the rope on the rope reel. For example, the motor 31 drives the first rope winding shaft 201 and the second rope winding shaft 202 to rotate simultaneously, the first rope winding shaft 201 and the second rope winding shaft 202 are in winding rope pulling states, the curtain separating rod 42 and the bottom rod 43 ascend simultaneously, the opening degrees of the first curtain 11 and the second curtain 12 are reduced, and the whole day and night curtain is quickly stored to the top; conversely, the motor 31 drives the first winding rope shaft 201 and the second winding rope shaft 202 simultaneously, and the first winding rope shaft 201 and the second winding rope shaft 202 are both in a state of releasing the pull rope, the opening degrees of the first curtain 11 and the second curtain 12 are both increased, and the whole day and night curtain is quickly lowered to the bottom.
It can be seen that the present invention is different from the driving arrangement of the conventional day and night curtains, the control driving member is arranged in the curtain separating rod 42 between the upper curtain (the first curtain 11) and the lower curtain (the second curtain 12), and the curtain separating rod 42 is provided with two rope winding shafts for winding or releasing the pull ropes of the first curtain 11 and the second curtain 12 respectively, so as to realize the effect of independent control of the day curtain and the night curtain without mutual influence; and only one motor 31 is arranged in the curtain separating rod 42, and the first rope winding shaft 201 and/or the second rope winding shaft 202 can be selectively controlled through the single-motor control 3, so that the requirement that a user only controls a day curtain or only controls a night curtain or simultaneously controls the day curtain and the night curtain according to the requirement is met.
When only one of the curtains is controlled (the cord reel of that curtain is controlled), the opening degree of the other curtain can be kept unchanged. When the two rope winding shafts are controlled simultaneously, if the states of the first rope winding shaft 201 and the second rope winding shaft 202 for winding and unwinding the pull ropes are opposite, the position of the curtain separating rod 42 can be changed only, and the switch between different opening ratios between the day curtain and the night curtain can be realized; if the first rope winding shaft 201 and the second rope winding shaft 202 are in the same state, the whole day and night curtain can be quickly released or quickly stored.
Therefore, the electric day and night curtain can drive the day curtain and the night curtain only by adopting one motor 31, and the driving and controlling cost is lower; the user can selectively control the day curtain and the night curtain without mutual influence, and the opening degree of one curtain body can be quickly and accurately changed; it is also possible to control both winding shafts simultaneously, keeping the distance between the top rod 41 and the bottom rod 43 unchanged, and changing only the position of the shade separating rod 42, thereby changing the duty ratio of the first shade 11 and the second shade 12. The day and night curtain driving control is very flexible and has extremely high control efficiency.
As shown in fig. 1 and 3, a solar panel 51 is disposed on the back side of the curtain separating rod 42, a storage battery is further disposed in the curtain separating rod 42, the solar panel 51 is electrically connected with the storage battery, and the storage battery is electrically connected with the working main board 52, the single-motor control 3 and the electromagnetic device 35. The solar panel 51 obtains solar energy, converts the solar energy into electric energy, and stores the electric energy in a storage battery to supply electric energy to each electronic component. Because the curtain separating rod 42 is positioned in the middle area of the curtain, when the solar panel 51 is arranged on the back surface (the surface facing the outside of the window) of the curtain separating rod 42, the curtain separating rod is not easy to be shielded by the protruding eave at the top of the window, and the solar panel 51 can absorb solar energy better. And electronic components of day night curtain set up in dividing curtain pole 42, solar panel 51 and the distance of battery, the distance of battery to work mainboard 52 and the distance of work mainboard 52 to other electronic components are nearer, do benefit to the wiring, practice thrift the wire rod and use.
In this embodiment, the first curtain 11 may be a day curtain, and the second curtain 12 may be a night curtain; or the first curtain 11 may be a night curtain and the second curtain 12 may be a day curtain.
As shown in fig. 4 and 5, in the present invention, in order to realize the function of driving the double winding rope shaft by the single motor, the single motor sub-control 3 includes a motor 31 and two gears 32 linked, the two gears 32 are an output wheel and a driving wheel, respectively, the output wheel is connected with the output shaft of the motor 31, and when the motor 31 rotates, the output wheel and the driving wheel rotate simultaneously. The output wheel and the driving wheel can be directly meshed and connected, and the rotation directions of the output wheel and the driving wheel are opposite at the moment; and a linkage gear can be arranged between the output wheel and the driving wheel, the simultaneous rotation is realized through the linkage gear, and the rotation directions of the output wheel and the driving wheel are the same at the moment.
In this embodiment, a linkage gear is provided between the output wheel and the driving wheel so that the output wheel and the driving wheel rotate in the same direction. The output wheel corresponds to an adjacent second spool 202 and the drive wheel corresponds to an adjacent first spool 201, each gear 32 having a disengaged condition and a closed condition with the corresponding spool. When the gear 32 is in a separated state with the rope winding shaft, the rope winding shaft is static and cannot be driven to rotate by the gear 32; when the gear 32 and the rope winding shaft are in a closed state, the rope winding shaft is driven by the gear 32 to rotate along with the motor 31. And at least one gear 32 and the corresponding rope winding shaft are in a closed state in the driving wheel and the output wheel, and the driving motor 31 drives at least one rope winding shaft to rotate.
In one embodiment, the single motor control 3 further comprises two electromagnetic means 35, which when activated, produce a magnetic attraction force, which magnetic attraction force is lost when the electromagnetic means 35 are turned off. An electromagnetic device 35 for controlling the closing and opening state between the first reel 201 and the driving wheel; another electromagnetic device 35 is used to control the closing and opening conditions between the second spool 202 and the output wheel.
Specifically, the first electromagnetic device is axially coupled to the central shaft 22 of the first rope reel 201, the first electromagnetic device rotates coaxially with the first rope reel 201, and the first electromagnetic device is slidable along the axial direction of the first rope reel 201. The end face of the driving wheel, which is close to the first rope winding shaft 201, is provided with an elastic magnetic part, when the first electromagnetic device generates magnetic attraction force, the first electromagnetic device is attracted with the elastic magnetic part, and because the position of the elastic magnetic part is unchanged, the first electromagnetic device is close to the elastic magnetic part under the action of the magnetic attraction force and slides on the central shaft 22, and is magnetically attracted with the elastic magnetic part and compresses the elastic magnetic part, so that the first rope winding shaft 201 is in closed connection with the driving wheel, and the first rope winding shaft 201 rotates under the driving of the driving wheel.
Similarly, the second electromagnetic device is axially coupled to the central shaft 22 of the second rope reel 202, the second electromagnetic device rotates coaxially with the second rope reel 202, and the second electromagnetic device is slidable along the axial direction of the second rope reel 202. The end face of the output wheel, which is close to the second rope winding shaft 202, is provided with an elastic magnetic piece, when the second electromagnetic device generates magnetic attraction, the second electromagnetic device is close to the elastic magnetic piece and then is connected with the elastic magnetic piece in a magnetic attraction mode and compresses the elastic magnetic piece on the output wheel, and the second rope winding shaft 202 is connected with the output wheel in a closing mode, so that linkage is achieved.
