[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0035] like Figure 1 As shown, the networked electric curtain includes a curtain body 100, a curtain track 200 and a networked motor 300. The networked motor 300 is connected to the curtain body 100 through a conveyor belt, and drives the curtain body 100 to move on the curtain track 200 to realize the opening and closing of the curtain body 100.

[0036] like Figure 2 As shown, the electric curtain in this embodiment is a multi-track curtain, and its curtain body 100 includes a main curtain 01 and a sub-curtain 02; the corresponding curtain track 200 includes a main curtain track 03 and a sub-curtain track 04, and the main curtain 01 and the sub-curtain 02 are correspondingly arranged on the main curtain track 03 and the sub-curtain track 04 through pulleys; the networked motor 300 includes a motor body and a networked module 09, and the motor body is divided into a main motor 05 for driving the main curtain 01 and a slave motor 06 for driving the sub-curtain 02, and the main motor 05 and the slave motor 06 are respectively controlled by a main controller 07 and a slave controller 08.

[0037] That is to say, Figure 2 , 3 As shown, a main motor 05 driving the main curtain 01, a slave motor 06 driving the auxiliary curtain 02, a main controller 07, a slave controller 08 and a networking module 09 constitute a curtain motor control system with a master-slave structure, which drives the main curtain 01 and / or the auxiliary curtain 02 on the curtain track 200 through a motor-driven belt to realize the opening and closing of the main curtain 01 and / or the auxiliary curtain 02.

[0038] Further preferably, the main motor 05 and the slave motor 06 of the electric curtain are connected to the wall at one end of the respective corresponding curtain track 200. The main motor 05 and the slave motor 06 are connected by a power line, and the main motor 05 leads to a power line 400 to connect to an external circuit to obtain power supply.

[0039] like Figure 2 , 3 As shown, the networking module 09 is arranged on the main motor 05 and connected to the main controller 07. Figure 5 As shown in the circuit schematic diagram of the networking module, the networking module 09 is a circuit module that connects the main controller 07 to the external intelligent network, so that the main controller 07 can obtain instructions from the user end of the external intelligent network through the networking module 09.

[0040] Specifically, Figure 3-6 As shown, the main controller 07 is connected to the main motor 05, and the slave controller 08 is connected to the slave motor 06. The main controller 07 and the slave controller 08 communicate with each other, and the main controller 07 can send control instructions to the slave controller 08 to realize the control of the slave motor 06 by the slave controller 08. That is to say, the main controller 07 parses the data received from the external intelligent network, distinguishes the function bits of the master and slave motors 06, directly converts the data controlling the main motor 05 into instructions to control the operation of the main motor 05, and transmits the data controlling the slave motor 06 to the slave controller 08, and the slave controller 08 independently controls the operation of the slave motor 06.

[0041] Figure 4 The circuit diagram of the motor and controller, where UP and DN are signal access terminals, Q1 and Q2 are transistors, K1 and K2 are forward and reverse relays, and U1 is the connection terminal of the controller and motor.

[0042] It should be understood that the curtain motor control system of the master-slave structure provided in this embodiment realizes independent control of the corresponding motors of the master curtain 01 and the auxiliary curtain 02 through only one networking module 09, that is, the master curtain 01 and the auxiliary curtain 02 can be opened and closed simultaneously or separately. In addition, the slave motor 06 does not need to be equipped with a separate networking module 09, saving hardware costs.

[0043] Preferably, the master controller 07 and the slave controller 08 communicate with each other in a bus 500 manner, and more preferably, a high-speed, synchronous communication method of a serial peripheral interface (hereinafter referred to as SPI) is adopted.

[0044] The communication mode of the SPI bus includes a control signal indicating whether the slave controller 08 is selected by the master controller 07, that is, only when the control signal is a predetermined enable signal, the operation of the master controller 07 on the slave controller 08 is effective. The master controller 07 completes the control of the communication and allows the input and output of data of different slave controllers 08 to be completed at the same time. This makes it possible for one master controller 07 to connect multiple slave controllers 08 on the same bus 500.

[0045] That is to say, for the electric curtains with single track or multiple tracks installed, one or more slave curtain tracks 200 can be quickly added. Only the corresponding slave controllers 08 and slave motors 06 need to be added. No extra settings are required to realize the control of multiple track curtains.

[0046] Preferably, the master controller 07 and the slave controller 08 use a single-chip microcomputer of model STM8S003FS to control the master motor 05 and the slave motor 06 .

[0047] like Figure 3 , 6As shown, a specific motor control method is described: the user end interacts with the external intelligent network for instructions, such as Xiaomi Mobile Internet of Things Platform, NetEase Cloud Intelligence, Tmall Genie, etc.; the external intelligent network transmits data to the networking module 09 according to the corresponding protocol specifications, and the networking module 09 converts the protocol into a serial port protocol format that can be recognized by the main controller 07. The main controller parses the protocol and determines and then executes the operation of the main motor 05, or sends data to the slave controller 08, and the slave controller 08 controls the slave motor 06.

[0048] like Figure 7 , 8 As shown, the main motor 05 includes a shell 10, and a slot A is provided on the shell 10. The networking module 09 can be movably installed in the shell 10 through the slot A and can be extended and extended, while retaining their respective integrity and independence, thereby separating the product and the networking module 09 to realize the change of the networking module 09.

[0049] like Fig. 9 As shown, the networking module 09 includes a base 91 and a networking chip 92 that can communicate with an external intelligent network and electric curtains at the same time. A space for accommodating the networking chip 92 is provided on the base 91, and the networking chip 92 is freely pluggable and connected to the base 91, so that the networking chip 92 can be replaced, and different networking chips 92 can be selected under the same hardware conditions according to different external intelligent networks.

[0050] Such a flexible matching solution is more adaptable to the changing market demands. On the one hand, it avoids the electric curtain being eliminated from the market due to the inability to change the networking module 09 of the electric curtain due to the development and changes of the external intelligent network; on the other hand, it gives consumers more choices and makes consumers feel better about the product experience.

[0051] like Fig. 9 , 11 As shown, a contact structure for connecting the main controller 07 with the networking chip 92 is provided in the housing 10 to realize the connection between the networking module 09 and the main controller 07. Specifically, the contact structure includes four contacts 3 connected to the corresponding serial ports of the networking chip 92. Preferably, a track T for the base 91 to move is provided in the housing 10, and the base 91 can be moved out of or into the housing 10 of the main motor 05 through a sliding structure. The networking module 09 may also include a locking structure F, which is provided between the housing 10 and the base 91. When the networking module 09 is inserted into a preset position, the locking structure locks the base 91, thereby ensuring the stability of the connection between the networking module 09 and the contacts 3 of the main controller 07.

[0052] like Fig.10 As shown, preferably, the networking chip 92 is placed on the upper surface of the base 91 , and the upper surface of the base 91 has a recessed groove K with one side open, and the networking chip 92 is placed in the recessed groove K.

[0053] like Figure 11-14 As shown, further preferably, the above-mentioned sliding structure and locking structure are combined into a linkage component 1, which not only drives the base 91 to move to the upper limit in the horizontal position to realize the movement of the networking module 09 in and out, making it convenient for users to change the networking module 09, but also locks the position of the base 91 at a preset position so that the networking module 09 is in stably contact with the contacts 3 of the main controller 07.

[0054] Specifically, the linkage component 1 is connected to the bottom of the base 91, and includes a swing rod 11, which extends from the inside of the housing 10 to the bottom of the networking chip 92. The bottom of the base 91 includes a linkage plate 2, which is provided with an annular groove 21, a low point 22 and a high point 23. The swing rod 11 swings at a fulcrum so that its front end can move in the annular groove 21 of the linkage plate 2 and can be switchably positioned at the low point 22 and the high point 23.

[0055] The fulcrum is located in the middle of the swing rod 11 , and the rear end of the swing rod 11 is connected to a fixed point 13 through a linkage spring 12 .

[0056] The middle part of the swing lever 11 is provided with a rotating shaft 14 as a fulcrum, the rotating shaft 14 is fixed in the housing 10, and is axially connected to the swing lever 11, so that the swing lever 11 can swing around the rotating shaft 14. A fixed shaft as a fixed point 13 is provided in the housing 10, and the rear end of the swing lever 11 is connected to the fixed point 13 through a linkage spring 12. The linkage spring 12 is a tension spring, which is in a tension state under normal conditions, and it always provides a contraction force to the swing lever 11, so that the swing lever 11 rotates clockwise with the rotating shaft 14 as the axis under natural force, so that the swing lever 11 can move in the annular groove 21.

[0057] like Fig.14 As shown, the annular groove 21 includes an inlet groove section 21a, a locking section 21b and an outlet groove section 21c. The inlet groove section 21a is located upstream of the clockwise rotation of the swing rod 11, and the outlet groove section 21c is located downstream. The low point 22 is located at the connection between the inlet groove section 21a and the outlet groove section 21c. The high point 23 is located in the locking section 21b of the inlet groove section 21a and the outlet groove section 21c.

[0058] A notch 24 is provided on one side of the annular groove 21 adjacent to the interior of the housing 10, and the swing rod 11 enters and exits the annular groove 21 through the notch 24. Furthermore, to ensure that the swing rod 11 accurately moves along the preset swing trajectory, the inlet groove section 21a is set to be deeper than the outlet groove section 21c, so when entering, the swing rod 11 enters the inlet groove section 21a because it is blocked by the mouth of the outlet groove section 21c.

[0059] like Fig.14As shown, a positioning block 25 is provided in the annular groove 21 of the linkage plate 2. The positioning block 25 divides the annular groove 21 into an inlet groove section 21a and an outlet groove section 21c. The locking section 21b is located at the front side of the positioning block 25. The high point 23 is a front end recessed portion of the positioning block 25. The low point 22 is located at the rear side of the rear end of the positioning block 25. The front end of the swing rod 11 is provided with a hook portion 11a that can be hooked in the front end recessed portion. Preferably, the recessed portion of the high point 23d is a U-shaped recessed portion, and correspondingly, the locking section 21b of the annular groove 21 presents a U-shaped track adapted to the U-shaped recessed portion.

[0060] Furthermore, preferably, Figure 11-13 As shown, an elastic push portion 010 is also provided inside the housing 10, which includes a push plate 4 and a thrust spring 5 acting on one side of the base 91. The side where the push plate 4 and the base 91 act also corresponds to the networking chip 92, and the contact 3 connecting the main controller 07 and the networking chip 92 is arranged on the side where the push plate 4 and the base 91 act, and is adjacent to the networking chip 92. The thrust spring 5 connects the side of the push plate 4 away from the base 91 of the networking module 09. The thrust spring 5 is in a compressed state under normal conditions, maintaining the elastic force that always pushes the base 91 forward. In order to maintain the stability of the push plate 4 when acting on the base 91, and to keep it balanced at all times so that the contact 3 and the networking chip 92 are in good contact, the thrust spring 5 is provided in two, and is symmetrically located at both ends of the push plate 4.

[0061] In actual operation, the networking chip 92 is placed on the base 91, and the base 91 is pressed inward from the notch A of the housing 10, so that the swing rod 11 rotates clockwise and enters the locking section 21b from the entry section 21a of the annular groove 21. Due to the contraction of the linkage spring 12, the swing rod 11 always maintains a backward force during the movement along the locking section 21b, so that the hook 11a is stuck at the high position 23 of the positioning block 25. At this time, the base 91 acts on the push plate 4, and the thrust spring 5 exerts an outward force on the push plate 4, so that the entire device is fixed in this position until the user applies an inward force next time.

[0062] When the user presses the base 91 inward again, the hook 11a leaves the high position 23, the lock of the base 91 is released, and the swing rod 11 continues to rotate clockwise into the slot section 21c, and the push spring 5 is deformed and rebounds to make the base 91 pop outward. The whole process is repeated in this way, so that the networking module 09 can be "pressed to get stuck, and then pressed to pop up", making it more convenient for users to replace the networking module 09.

[0063] It should be understood that the networking module and the device body are detachable, and the networking chip 92 can be replaced from the base 91 of the networking module. The advantage of this design is not only that the networking module can be applied to different external intelligent networks, but also that the product can be used normally after the module is separated, showing a "plug and play" use effect.

[0064] At the same time, the networking module provided in this embodiment is not limited to the electric curtain device. The networking module can be directly placed in other different devices that comply with this design principle to facilitate the realization of intelligent and integrated home furnishing.

[0065] The specific connection structure between the networked motor 300 and the networked module 09 provided in this embodiment realizes “press down to lock, press again to pop up”, which can achieve the above-mentioned effect more reliably and efficiently.

[0066] The above is a detailed introduction to the electric curtain networking module, networking motor, and networking electric curtain provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
