Description

Technical Field

[0001] This invention relates to the field of curtain technology, and in particular to a double-layer day and night curtain system and its control method. Background Technology

[0002] The practical functions of curtains include: blocking light, allowing light in while providing privacy, and decoration. Most household curtains are left-right opening curtains, typically consisting of a layer of sheer fabric and a layer of blackout fabric. During the day, the sheer fabric allows light in while maintaining privacy; at night, the blackout fabric completely blocks out light, promoting rest and sleep. However, this combination of fabrics is expensive, easily attracts dust and bacteria, is difficult to clean, and doesn't offer a clean aesthetic.

[0003] Day and night honeycomb blinds consist of sheer fabric and blackout fabric, stacked vertically. This allows light to pass through during the day while maintaining privacy, and provides complete blackout at night for restful sleep. The fabric's unique hexagonal structure also offers heat and sound insulation. Furthermore, when pulled back during the day, it prevents dust accumulation and is easy to clean. Due to the fabric's special properties, light is filtered through it, resulting in a softer, warmer, and simpler feel, making it a blind that combines excellent functionality with a beautiful decorative effect. However, current day and night blinds use a stacked structure, leading to complex construction, difficult threading during production, low efficiency, and high technical requirements for assembly and components. This results in high after-sales costs and complex control, making the overall price high and difficult for mass-market consumers. Therefore, reducing the quality requirements and production complexity of components is a pressing issue we need to address. Summary of the Invention

[0004] The technical solution to be solved by the present invention is to provide a double-layer day and night curtain system that is simple in structure, easy to produce, easy to control, and low in cost.

[0005] The technical solution adopted in this invention is: a double-layer day and night curtain system, which includes an upper track, a transmission mechanism disposed in the upper track, two sets of curtain assemblies connected to the transmission mechanism, and a drive mechanism connected to the upper track for driving the transmission mechanism, wherein the two sets of curtain assemblies are arranged in parallel.

[0006] Preferably, the transmission mechanism consists of two sets, which are arranged inside the upper track. Each set includes a coiler and a drive shaft. The coiler is sleeved on the drive shaft, and the two sets of curtain assemblies are respectively arranged below the two sets of transmission mechanisms.

[0007] Preferably, the drive mechanism includes a first motor, a first reducer, a second reducer, a second motor, and a controller, wherein the first motor and the second motor are both electrically connected to the controller, the first motor is connected to one of the transmission mechanisms through the first reducer, and the second motor is connected to another transmission mechanism through the second reducer.

[0008] Preferably, the upper track is provided with an installation cavity, a baffle is provided on one side of the installation cavity, and the other side of the installation cavity is for the installation of the drive mechanism. Both sets of transmission mechanisms are set in the installation cavity, and the transmission mechanism also includes a support seat for supporting the winding reel.

[0009] Preferably, the middle part of the mounting cavity is provided with a partition plate for dividing the mounting cavity into two mounting cavities, and two sets of transmission mechanisms are respectively arranged in the two mounting cavities.

[0010] Preferably, the drive mechanism further includes a mounting housing, in which the first motor, the first reducer, the second reducer, the second motor, and the controller are all mounted. After installation, the drive mechanism is U-shaped, with the portion of the mounting housing accommodating the first motor and the second motor extending into the two mounting cavities.

[0011] Preferably, both the first motor and the second motor are provided with Hall signal boards at their ends, and the Hall signal boards are arranged parallel to the main control board in the controller.

[0012] Preferably, each transmission mechanism includes two cable winders and a drive shaft. The two cable winders are both mounted on the drive shaft. The output shaft on the first motor side is connected to the drive shaft of one of the transmission mechanisms through a first reducer, and the output shaft on the second motor side is connected to the drive shaft of the other transmission mechanism through a second reducer.

[0013] Preferably, each transmission mechanism includes two winding heads and two drive shafts. The two winding heads are respectively sleeved on the two drive shafts. There are two first reducers and two second reducers. The output shaft on one side of the first motor is connected to one of the drive shafts of one transmission mechanism through one of the first reducers. The output shaft on the other side of the first motor is connected to another drive shaft of one transmission mechanism through the other first reducer. The output shaft on one side of the second motor is connected to one of the drive shafts of another transmission mechanism through one of the second reducers. The output shaft on the other side of the second motor is connected to another drive shaft of another transmission mechanism through the other second reducer.

[0014] Preferably, the curtain assembly includes a curtain body, a pull cord, and a lower beam. The lower beam is located below the transmission mechanism and is connected to the winder via the pull cord. The curtain body is located between the upper track and the lower beam, and the pull cord passes through the curtain body.

[0015] Preferably, it also includes an X1 remote controller, an X2 remote controller, a first button module, a second button module, and a communication module. The first button module, the second button module, and the communication module are all electrically connected to the controller. The X1 remote controller and the X2 remote controller are connected to the controller through the communication module. The first button module is used to pair the X1 remote controller with the controller by pressing a button, and then control one set of drive mechanisms to work through the X1 remote controller. The second button module is used to pair the X2 remote controller with the controller by pressing a button, and then control the other set of drive mechanisms to work through the X2 remote controller.

[0016] Preferably, the lower end of the upper track is provided with two mounting slots for installing two sets of curtain components, and the curtain components are detachably connected in the mounting slots.

[0017] Preferably, the curtain assembly is inserted into the mounting groove, and after the curtain assembly is installed in the mounting groove, one end of the curtain assembly abuts against the baffle, and the other end of the curtain assembly abuts against the mounting housing.

[0018] A control method for a double-layer day and night curtain system, comprising two remote controls, namely remote control X and remote control Y, wherein remote control X is used to control the left and right curtain components, and remote control Y is used to control the top and bottom curtain components, and includes the following steps:

[0019] A1. Install the curtain components as needed, and then select the corresponding remote control according to the installed curtain components. If the curtain components are set to left and right, select remote control X, then pair remote control X with the controller, and then proceed to the next step; if the curtain components are set to top and bottom, select remote control Y, then pair remote control Y with the controller, and then proceed to A3.

[0020] A2. If the remote control X is successfully paired with the controller, the controller's control method will automatically switch to the control method for the left and right curtain components.

[0021] A3. If the remote control Y is successfully paired with the controller, the controller's control method will automatically switch to controlling the upper and lower curtain components.

[0022] Preferably, the remote control X has two sets of buttons, namely a first set of buttons and a second set of buttons. Each set of buttons includes an up button, a stop button, and a down button. The control method for controlling the left and right curtain components mentioned in step A2 includes the following steps:

[0023] B1. Press the up button in the first group of buttons, and one of the drive mechanisms will move the corresponding curtain component upward; press the down button in the first group of buttons, and one of the drive mechanisms will move the corresponding curtain component downward; press the stop button in the first group of buttons, and one of the drive mechanisms will stop, thus bringing the corresponding curtain component to a standstill.

[0024] B2. Press the up button in the second group of buttons, and another drive mechanism will drive the corresponding curtain component to move upward; press the down button in the second group of buttons, and another drive mechanism will drive the corresponding curtain component to move downward; press the stop button in the second group of buttons, and another drive mechanism will stop, thus bringing the corresponding curtain component to a standstill.

[0025] Preferably, the remote control Y has two sets of buttons, namely a first set of buttons and a second set of buttons. Each set of buttons includes an up button, a stop button, and a down button. The two drive mechanisms are a first drive mechanism and a second drive mechanism. The curtain components arranged vertically include, from top to bottom, an upper track, a first curtain body, a first lower beam, a second curtain body, and a second lower beam. The first drive mechanism controls the first lower beam, the first set of buttons controls the first lower beam, the second drive mechanism controls the second lower beam, and the second set of buttons controls the second lower beam. The control method for controlling the vertically arranged curtain components mentioned in step A3 includes the following steps:

[0026] C1. If you press the up or down key in the first group of buttons or the second group of buttons to move the first lower beam up or down, or to move the second lower beam up or down, the first and second lower beams will move independently.

[0027] C2. If the stop button of one of the groups is pressed, the corresponding drive mechanism will stop running, causing the corresponding first or second lower beam to stop.

[0028] Preferably, in the operating mode, the controller obtains the stroke data of the first motor in the first drive mechanism and the second motor in the second drive mechanism in real time, then calculates the real-time position of the first lower beam and the second lower beam, and compares it in real time with three preset parameters: the upper limit position of the first lower beam, the lower limit position of the second lower beam, and the safe distance between the first lower beam and the second lower beam. Once these parameters are reached, the corresponding drive mechanism stops operating.

[0029] Compared with existing technologies, this invention, employing the above structure and method, has the following advantages: By setting two curtain components and arranging them parallel to each other, the vertical arrangement is changed to a horizontal arrangement, ensuring the same effect for both day and night curtains. However, the structure is simplified to the effect of two ordinary curtains, significantly reducing production difficulty and making assembly very simple, thus facilitating product widespread adoption. Furthermore, because it consists of two independent curtain systems, it can be used in combinations of various curtain types, not just honeycomb curtains, providing consumers with more choices to meet their personalized needs.

[0030] Furthermore, with the popularization of smart living, the intelligentization of electric curtains is an inevitable trend. We have innovatively integrated two motor systems into one control system, that is, using only one controller. This allows us to share the components on the controller while independently controlling two sets of curtains, making the control logic very simple, reducing programming difficulty, reducing after-sales issues, and making it easier to interface with various control platforms.

[0031] The curtain assembly can be detachably connected to the mounting groove on the lower end face of the upper track. This allows for selection of curtain assemblies as needed, such as the left-right combination assemblies described in this application, or the top-bottom combination assemblies of existing technology. Then, a corresponding remote control is matched to the installed curtain assembly, and the controller automatically selects the appropriate control mode based on the matched remote control. This allows for the installation of curtains with either a left-right or top-bottom combination according to the user's needs, satisfying a wider range of customer requirements.

[0047] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0048] Example 1:

[0049] A double-layer day and night curtain system, such as Figures 1-8 As shown, it includes an upper track 1, a transmission mechanism 2, a drive mechanism 3, a curtain assembly 4, an X1 remote control, and an X2 remote control, wherein:

[0050] The upper track 1 has an installation cavity 14 inside along its width direction. A partition 17 is provided in the middle of the installation cavity 14, which divides the installation cavity 14 into two installation cavities 14, namely the first installation cavity and the second installation cavity. One side of the two installation cavities 14 is blocked by a baffle 15. The drive mechanism 3 is installed on the other side of the installation cavity 14. The lower end face of the upper track 1 is provided with two installation grooves 13, namely the first installation groove and the second installation groove. During installation, the first installation groove is away from the window.

[0051] The transmission mechanism 2 consists of two sets, which are arranged side by side in the upper track 1. Each set of transmission mechanism 2 includes a first winding device, a second winding device, and a drive shaft 6. The first winding device and the second winding device are both sleeved on the drive shaft 6 and are driven to rotate by the drive shaft 6. The mounting cavity 14 of the upper track 1 is also provided with a support seat 16 for mounting the winding device. Each winding device 5 corresponds to a support seat 16. Each winding device 5 is wound with a pull rope 12. One set of transmission mechanism 2 is installed in the first mounting cavity, and the other set of transmission mechanism 2 is installed in the second mounting cavity.

[0052] The drive mechanism 3 includes a first motor 7, a first reducer, a second reducer, a second motor 8, a controller 9, and a mounting housing 18. The first motor 7, the first reducer, the second reducer, the second motor 8, and the controller 9 are all installed inside the mounting housing 18. The mounting housing 18 containing the controller 9 forms the bottom, while the mounting housings containing the two motors form the two protruding portions of the bottom. Hall effect signal boards are provided at the ends of both the first motor 7 and the second motor 8, and these Hall effect signal boards are arranged parallel to the main control board inside the controller. Thus, the installed mounting housing 18 is U-shaped. Both the first motor 7 and the second motor 8 are electrically connected to the controller 9, allowing the controller 9 to control their operation. Both the first motor 7 and the second motor 8 have outputs from only one side; that is, they only have outputs on one side. The output shaft of the first motor 7 is connected to the drive shaft 6 of the first transmission mechanism 2 via a first reducer, so that the first motor 7 can drive the first transmission mechanism 2 to work, and the mounting housing of the first motor 7 extends into the mounting cavity of the first transmission mechanism 2; the output shaft of the second motor 8 is connected to the drive shaft 6 of the second transmission mechanism 2 via a second reducer, so that the second motor 8 can drive the second transmission mechanism 2 to work, and the mounting housing 18 of the second motor 8 extends into the mounting cavity of the second transmission mechanism 2; the mounting housing 18 of the controller 9 is set outside the mounting cavity 14 of the upper rail 1, and is also provided with an end cover, so that the end cover can be opened and the controller 9 inside the mounting housing 18 can be taken out when maintenance is required.

[0053] Furthermore, the controller 9 is also equipped with a first button module, a second button module, and a communication module. The first button module, the second button module, and the communication module are all electrically connected to the controller 9. The first button module and the second button module are both located on both sides of the mounting housing 18. The communication module is used for wireless communication with the X1 remote controller and the X2 remote controller. The first button module is used to pair the X1 remote controller with the controller 9 through a button, and then control one of the drive mechanisms 3 through the X1 remote controller. The second button module is used to pair the X2 remote controller with the controller 9 through a button, and then control the other drive mechanism 3 through the X2 remote controller.

[0054] The curtain assembly 4 consists of two sets, which are arranged in parallel and aligned. Each set includes a curtain body 10, a pull cord 12, and a lower beam 11. The curtain body 10 of both sets of curtain assemblies 4 is made of honeycomb material. The lower beam 11 of each set of curtain assemblies 4 is located directly below the drive shaft 6 of the corresponding transmission mechanism 2. One end of the pull cord 12 of each set of curtain assemblies 4 is connected to the winding device 5 in the corresponding transmission mechanism 2, and the other end passes through the curtain body 10 and connects to the lower beam 11. Since there are two winding devices 5 on each set of transmission mechanism 2, there are also two pull cords 12. The two pull cords 12 are connected to the two winding devices 5 respectively. The lower end of the curtain body 10 is fixed to the lower beam 11, and the upper end of the curtain body 10 is connected to the two mounting grooves 13 on the lower end face of the upper track 1. That is, the opening and closing of the curtain body 10 can be controlled by pulling the pull cord 12.

[0055] The control principle of this embodiment is as follows: Remote controller X1 is used to control the first motor 7, which in turn controls one set of transmission mechanisms 2 and curtain assembly 4; remote controller X2 is used to control the second motor 8, which in turn controls another set of transmission mechanisms 2 and curtain assembly 4. During pairing, the user needs to press the first button module to pair the X1 remote controller with the controller 9. After pairing, the first motor 7 can be controlled via the X1 remote controller. Similarly, the user can press the second button module to pair the X2 remote controller with the controller 9. After pairing, the second motor 8 can be controlled via the X2 remote controller. Essentially, the two remote controllers independently control the two motors, with no connection between them. The control logic is simpler: pressing the up button moves the corresponding lower beam upwards, pressing the down button moves the corresponding lower beam downwards, and pressing the stop button stops the corresponding lower beam. Since the specific pairing process between the remote controller and the controller 9 is relatively conventional in existing technology, it is not elaborated upon here.

[0056] Example 2:

[0057] like Figure 9As shown, the difference from Embodiment 1 is that in Embodiment 2, each transmission mechanism 2 includes two winding heads 5 and two drive shafts 6. Each shaft drive is fitted with a winding head 5, and this winding head 5 rotates together with the drive shaft 6. The drive mechanism 3 includes two motors, four reducers, a controller, and a mounting housing. The two motors, four reducers, and one controller are all housed within the mounting housing, forming an integrated drive mechanism placed in the middle of the upper rail 1. One motor and two reducers match one transmission mechanism 2, and the motors output from both sides, so each motor has a reducer on both sides. The reducers on both sides are then connected to the two drive shafts 6, driving the drive shafts 6 to rotate, which in turn drives the winding heads 5. In short, in Embodiment 1, the motor outputs from one side, so the drive mechanism 3 is located on one side of the upper rail 1; while in Embodiment 2, the motor outputs from both sides, so the drive mechanism 3 is located in the middle of the upper rail 1.

[0058] Example 3:

[0059] like Figure 10 As shown, the difference from Embodiment 1 is that in Embodiment 3, the upper end of the curtain body 10 is plugged into the mounting groove 13 on the lower end face of the upper track 1. After the upper end of the curtain body 10 is plugged into the mounting groove 13, one end abuts against the baffle 15 and the other end abuts against the mounting housing 18. That is, when the user installs the housing, the curtain assembly can be inserted into the mounting groove 13 first, and then the drive mechanism can be installed. When disassembling, the drive mechanism can be removed first, and then the curtain assembly 4 can be easily removed from the mounting groove 13. This makes it easy to replace the curtain assembly 4. The background technology of this application mentions a curtain assembly 4 that is set up vertically, such as... Figure 11 As shown, from top to bottom, it includes an upper track 1, a first curtain body 19, a first lower beam 20, a second curtain body 21, and a second lower beam 22. This is a conventional day and night curtain in the prior art, so it is not elaborated here. There is also another type of curtain component 4, which is the left-right arranged curtain component 4 mentioned in Embodiment 1 of this application. In this embodiment, these two types of curtain components 4 can be interchanged. The physical structure change is that if it is necessary to install the up-down arranged curtain component 4, the first curtain body 19 of the curtain component 4 is installed into the first mounting groove. If it is necessary to install the left-right arranged curtain component 4, the curtain body 10 of the curtain component 4 is installed into the first mounting groove and the second mounting groove respectively. Each type of curtain component 4 is compatible with a remote control. The left-right arranged curtain component 4 corresponds to remote control X, and the up-down arranged curtain component 4 corresponds to remote control Y. When the left-right arranged curtain component 4 is installed, the installation is similar to Figure 1As shown, the remote control X is paired with the controller 9. After successful pairing, the controller 9 automatically switches to a control method that controls the left and right curtain components 4. This means the two curtain components 4 operate independently, similar to controlling two separate honeycomb blinds. When the curtain components 4 are installed vertically, and the installation position is within the first mounting slot, the installation is as follows: Figure 11 As shown, remote controller Y is paired with controller 9. After successful pairing, controller 9 automatically switches to a control method that controls the upper and lower curtain components 4. This means the two curtain components 4 need to be interconnected and require mutual feedback for coordinated control. Both remote controllers X and Y have control buttons on their front, including a first up button, a first down button, a first stop button, a second up button, a second down button, and a second stop button. The back of both remote controllers X and Y has a switch for toggling between debugging and usage modes. Additionally, the back of both remote controllers X and Y has travel confirmation buttons and pairing buttons, including an up travel confirmation button and a down travel confirmation button.

[0060] The control method in Example 3 includes the following steps:

[0061] A1. Install the curtain components as needed, and then select the corresponding remote control according to the installed curtain components. If the installed curtain components are left and right curtain components, select remote control X, pair remote control X with controller 9, and then proceed to the next step; if the installed curtain components are up and down curtain components, select remote control Y, pair remote control Y with controller, and then proceed to A3.

[0062] A2. If remote controller X is successfully paired with the controller, the controller will automatically switch to the control method corresponding to remote controller X. The control method for the left and right curtain components is separate control. Its control principle is equivalent to combining two simple honeycomb curtains together, but the control is separate and the two do not need to interact.

[0063] A3. If the remote controller Y is successfully paired with the controller, the controller will automatically switch to the control method corresponding to the remote controller Y. The control method for controlling the upper and lower curtain components is a combination control. The control requires feedback, and this control method is already used in existing day and night curtain technology, so it will not be elaborated on here.

[0064] The pairing method in step A1 includes the following steps:

[0065] A11. Press and hold the first button component or the second button component. At this time, the controller enters the pairing state.

[0066] A12. Switch the toggle switch on remote control X or remote control Y to debug mode, and then press and hold the pairing button on the back of the remote control.

[0067] A13. If the curtain assembly executes the preset successful pairing action within the set time, the pairing is considered successful; if the curtain assembly does not execute the preset successful pairing action, the pairing is considered unsuccessful.

[0068] The control method for the left and right curtain components in A2 includes the following steps:

[0069] B1. Press the up button in the first group of buttons, and one of the drive mechanisms will move the corresponding curtain component upward; press the down button in the first group of buttons, and one of the drive mechanisms will move the corresponding curtain component downward; press the stop button in the first group of buttons, and one of the drive mechanisms will stop, thus bringing the corresponding curtain component to a standstill.

[0070] B2. Press the up button in the second group of buttons, and another drive mechanism will drive the corresponding curtain component to move upward; press the down button in the second group of buttons, and another drive mechanism will drive the corresponding curtain component to move downward; press the stop button in the second group of buttons, and another drive mechanism will stop, thus bringing the corresponding curtain component to a standstill.

[0071] The control method for the vertically positioned curtain components in A3 includes the following steps:

[0072] C1. If you press the up or down key in the first group of buttons or the second group of buttons to move the first lower beam up or down, or to move the second lower beam up or down, the first and second lower beams will move independently.

[0073] C2. If the stop button of one of the groups is pressed, the corresponding drive mechanism will stop running, causing the corresponding first or second lower beam to stop.

[0074] Furthermore, in operation mode, the controller obtains the stroke data of the first motor in the first drive mechanism and the second motor in the second drive mechanism in real time, then calculates the real-time position of the first lower beam and the second lower beam, and compares it in real time with three preset parameters: the upper limit position of the first lower beam, the lower limit position of the second lower beam, and the safe distance between the first lower beam and the second lower beam. Once these parameters are reached, the corresponding drive mechanism stops operating.

[0075] How to set up / down travel:

[0076] D1. Switch the toggle switch on the back of the remote control to debug mode;

[0077] D2. Use the control buttons on the front of the remote control to move the curtain assembly to the set upper travel position, then press and hold the upper travel confirmation button on the back of the remote control to confirm the upper travel position.

[0078] D3. Use the control buttons on the front of the remote control to operate the curtain assembly to the set lower travel position, then press and hold the lower travel confirmation button on the back of the remote control to confirm the lower travel position.

[0079] Example 4:

[0080] like Figure 12 As shown, the difference from Embodiment 3 is that Embodiment 4 also includes a two-position switch connected to the controller 9. This eliminates the need to rely on a paired remote control for control method changes; instead, the switch can be adjusted by the user. Specifically, when the switch is in position one, the control method adapts to left-right curtain components 4; when in position two, the control method adapts to up-down curtain components 4. Essentially, after installing the curtain components 4, the user needs to adjust the switch according to the installed components. For left-right curtain components 4, the switch should be set to position one, and then the remote control X should be paired with the controller 9. For up-down curtain components 4, the switch should be set to position two, and then the remote control Y should be paired with the controller 9.

[0081] Example 5:

[0082] like Figure 13 As shown, the difference from Embodiment 1 is that Embodiment 5 also includes an energy storage battery. In this embodiment, the energy storage battery is a lithium battery, and the energy storage battery is installed in one of the mounting cavities 14 and electrically connected to the controller 9 for power supply. During normal use, it will be in a fully charged state. When the power is off, the electrical energy in the energy storage battery will supply the controller 9, so that the drive mechanism 3 can also be controlled to work during the power outage.

[0083] Example 6:

[0084] like Figure 14 As shown, the difference from Embodiment 1 is that in Embodiment 5, the curtain 10 is not two honeycomb curtains, but one honeycomb curtain plus one Venetian blind. Since it is two independent curtain systems, it can be used in various combinations of curtain types. Therefore, it is not limited to the combination of two honeycomb curtains in Embodiment 1, nor is it limited to the combination of Venetian blind and honeycomb curtain in Embodiment 6.
