DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and some implementation methods.

[0019] exist Figure 1-Figure 5In the invention, an electric curtain linear guide device comprises a device body 1, wherein the device body 1 comprises a moving module 2 for driving the curtain to move, a static module 3 for supporting the curtain and for moving the moving module 2, the moving module 2 is movably matched with the static module 3, the moving module 2 is an internally hollow cylinder, and comprises a plurality of magnetically coupled soft iron cores 201 for sliding coupling with the magnetic field of the static module 3, a plurality of magnetically coupled iron core isolation layers 202 for spacing the magnetically coupled soft iron cores 201, and a microcontroller 203. In general, there are three magnetically coupled soft iron cores 201 and two magnetically coupled iron cores. The isolation layer 202 can be selected according to actual conditions. The magnetic coupling soft iron core 201 and the magnetic coupling iron core isolation layer 202 are both cylindrical. The magnetic coupling iron core isolation layer 202 is located between two adjacent magnetic coupling soft iron cores 201. The material of the magnetic coupling iron core isolation layer 202 is ordinary plastic and is located between two adjacent magnetic coupling soft iron cores 201. The output end of the microcontroller 203 is connected to the input end of the magnetic coupling soft iron core 201. The static module 3 is cylindrical, including a static iron core 301 that is slidingly coupled with the magnetic field of the dynamic module 2, and a multi-tap coil 30 4. The static core 301 is made of a common soft iron core and is slidingly coupled with the magnetic field of the moving module 2. The multi-tap coil 304 is made of an ordinary pure copper enameled wire wound on the static core 301. The static core 301 includes a plurality of thick cores 302 arranged horizontally in sequence. A thin core 303 is connected between two adjacent thick cores 302. The number of thick cores 302 and the number of thin cores 303 can be determined according to the width of the window. The wider the window, the longer the length of the static core 301 is required, so more thick cores 302 and thin cores 303 are required. On the contrary, the smaller the number, the multi-tap coil 304 is wrapped around the thin iron core 303, and each multi-tap coil 304 is energized. The magnetically coupled soft iron core 201 of the moving module 2 moves synchronously from left to right (or from right to left) in a straight line under the coupling action of the energized multi-tap coil 304, and its movement speed is controlled by the step-by-step frequency of the microcontroller 203, and its coupling force is controlled by the energized current of the multi-tap coil 304 and the number of turns of the multi-tap coil 304; when working, the hollow position inside the moving module 2 is installed on the static module 3, so that the moving module 2 moves on the static module 3.

[0020] In this embodiment, a dynamic module shell 204 for protecting the dynamic module 2 is disposed on the outside of the dynamic module 2, and a static module shell 305 for protecting the static module 3 is disposed on the outside of the static module 3.

The dynamic module shell 204 and the static module shell 305 are both made of stainless steel, plastic or the like.

[0021] In this embodiment, one end of the movable module housing 204 is connected and fixed to the curtain, and may be fixed by adhesive or the like. The movement of the movable module 2 drives the curtain to move, thereby achieving the purpose of automatically opening and closing the curtain.

[0022] In this embodiment, the device body 1 is provided with a power cord 101 connected to an external power source, and the output end of the power cord 101 is respectively connected to the input end of the static module 3 and the input end of the dynamic module 2, and provides power to the dynamic module 2 and the static module 3 after the power is turned on.

[0023] In this embodiment, the microcontroller 203 is provided with a wireless transmitter connected to a mobile terminal, which is an electronic device such as a mobile phone or a tablet. The mobile terminal can be wirelessly connected via WiFi, Bluetooth, etc., and then the microcontroller 203 is driven by the mobile terminal to operate the moving module 2.

[0024] In this embodiment, both ends of the static module 3 are installed on both sides of the top of the window and can be fixed by means of screws or the like.

[0025] In this embodiment, the center of the thick iron core 302 and the center of the thin iron core 303 are on the same horizontal plane, so the surfaces of the thick iron core 302 and the thin iron core 303 are uneven, thereby preventing the multi-tap coil 304 from being wound on the thin iron core 303.

[0026] In this embodiment, the microcontroller 203 is a common electrical component, such as a single chip microcomputer of the AT89C2051 or TMS320VC5509A model.

[0027] In this embodiment, the control circuit of the utility model is a common circuit in the circuit field. The device of the utility model can be connected to an external power supply or a built-in battery through a power cord to provide power for the device. Technicians in the relevant technical field can implement it and will not be elaborated here.

[0028] During the specific implementation of the utility model: during use, the curtain can be fixed on the moving module housing 204 by means of adhesive or the like, the power is turned on to energize each multi-tap coil 304, and the device body 1 is operated at the mobile end. After the moving module 2 is energized, the multi-tap coil 304 synchronously performs linear motion from left to right (or from right to left) under the coupling effect, and its movement speed is controlled by the step-by-step frequency of the microcontroller 203, and its coupling force is controlled by the coil energization current and the number of coil turns. When the moving module 2 moves left and right, the curtain is synchronously driven to move left and right, thereby achieving the purpose of automatically closing or opening the curtain.
