[0019] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] Example 1 Please refer to Figure 1-Figure 9 The embodiment of the present invention provides a wireless charging structure 200, the wireless charging structure 200 includes at least one power supply component 2, the power supply component 2 is used to supply power to the opening and closing structure 100 of the curtain, and the power supply component 2 includes: A power supply base 21, used to supply power to the opening and closing structure 100, the power supply base 21 comprises a base 211 and a first positioning member 212, one end of the first positioning member 212 is placed above the base 211 in the z-axis direction and one end of the first positioning member 212 is built into the base 211; An electric wire, one end of which is connected to a power source, and the other end of which is inserted into the power supply socket 21 for supplying power to the power supply socket 21; The power supply base 21 has a power transmission coil 216 built therein. The power transmission coil 216 generates a power supply magnetic field when energized. Two ends of the power transmission coil 216 abut against the base 211 and the first positioning member 212 in the z-axis direction.

[0023] Specifically, the opening and closing device of the curtain includes an opening and closing structure 100 and a wireless charging structure 200. Hooks are arranged on both sides of the opening and closing structure 100, and the hooks are connected to the structure installed on the guide rail, so that the opening and closing structure 100 can be installed on the guide rail.

[0024] After the opening and closing structure 100 is installed on the guide rail of the curtain, the installation position of the wireless charging structure 200 is selected according to the distance between the guide rail and the wall or other structures used to fix the wireless charging structure 200, and the wireless charging structure is installed.

[0025] Generally, the installation method of the wireless charging structure 200 is selected according to the material of the location where the wireless charging structure 200 is installed. For example, when the wireless charging structure 200 is installed on a wall, if the material of the wall is cement, the wireless charging structure 200 is directly installed on the wall with traceless nails. If the wall is made of ceramic, acrylic double-sided tape can be used to stick it on the base 211 to fix the power supply base 21 on the wall by sticking.

[0026] After the power supply seat 21 is installed at the installation position, the wire connected to the power supply seat 21 is connected to the indoor power supply. Generally, the wire is connected to a plug, and the plug is installed on the socket. As long as the plug is not unplugged, the power supply can be always connected to the power transmission coil 216 in the power supply seat 21. By controlling the length of the wire, the socket can be set at any position.

[0027] In one embodiment, the base 211 is an integrated structure (not shown in the figure), a cavity is provided inside the base 211, a power transmission coil 216 is stored in the cavity, and a circular opening 2118 is provided at one end close to the opening and closing structure 100. The first positioning member 212 is a truncated cone structure with a hollow bottom, the first positioning member 212 passes through the circular opening 2118 and the end with a larger outer diameter is placed in the base 211 to fix the first positioning member 212 on the base 211, so as to realize the support connection of the base 211 to the first positioning member 212; the end with a smaller diameter of the first positioning member 212 is placed outside the base 211, so as to accurately align and fit the opening and closing structure 100, so as to realize efficient wireless charging of the opening and closing structure 100. The provision of the first positioning member 212 also shortens the distance between the power supply component 2 and the opening and closing structure 100, thereby improving the charging efficiency.

[0028] The power transmission coil 216 is disposed in the charging base to generate a power supply magnetic field. When the first positioning member 212 is attached to the opening and closing structure 100, the opening and closing structure 100 can enter the power supply magnetic field to achieve charging.

[0029] The power transmission coil 216 is placed in the cavity and one end thereof abuts against the base 211 in the z-axis direction, and the other end thereof passes through the bottom of the first positioning member 212 and abuts against the top of the first positioning member 212. The power transmission coil 216 is fixed between the first positioning member 212 and the base 211 so that the direction of the magnetic field generated by the power transmission coil 216 is in the z-axis direction, and at the same time, the power transmission coil 216 is prevented from shaking and affecting the magnetic field direction of the power supply magnetic field, thereby preventing the charging of the opening and closing device from being affected.

[0030] When the wireless charging structure 200 is installed on a wall, the z-axis direction is perpendicular to the wall, so that when the opening and closing structure 100 is attached to the first positioning member 212, the power supply component 2 can supply power to the opening and closing structure 100.

[0031] The present invention proposes a wireless charging structure 200, which can charge the opening and closing structure 100 of the curtain without disassembly. The wireless charging structure 200 realizes wireless charging of the opening and closing structure 100 through a power supply component 2 arranged near the guide rail, wherein the power supply component 2 includes a power supply seat 21 and a wire, and the power supply seat 21 has a power transmission coil 216 built in. The power supply magnetic field generated by the power transmission coil 216 after being energized can charge the opening and closing structure 100 without direct contact, which solves the problem of frequent disassembly and assembly of the opening and closing structure 100 for charging in the prior art, and improves the convenience and safety of use; At the same time, the power supply seat 21 ensures accurate spatial alignment with the opening and closing structure 100 through the first positioning member 212 inside the power supply seat 21, thereby ensuring an efficient wireless charging process; The present invention not only solves the problem of inconvenient charging of the traditional curtain opening and closing structure 100, but also takes into account the ease of installation and adaptability to various types of curtain rails, providing users with an efficient, safe and easy-to-maintain wireless charging device.

[0032] In one embodiment, if Figure 2-Figure 4 As shown, the base 211 is a structure that can be quickly disassembled and installed, and the base 211 includes a bottom plate 2111 and an outer shell 2112; the outer shell 2112 is penetrated in the z-axis direction, and a first connecting portion 2113 extending outward is provided on the bottom side thereof; The chassis 2111 is provided with a second connection portion 2114 , and a connection member 213 passes through the first connection portion 2113 and the second connection portion 2114 to fix the outer shell 2112 on the chassis 2111 to form a cavity.

[0033] Specifically, the outer shell 2112 is an annular structure. After the outer shell 2112 and the chassis 2111 are installed, a cavity is formed inside, and the power transmission coil 216 is arranged in the cavity. A first connecting portion 2113 is symmetrically provided on the outer wall of the outer shell 2112 close to the chassis 2111, and two symmetrical first connecting portions 2113 are respectively arranged at the two ends of the diameter of the outer shell 2112. The first connecting portion 2113 is provided with a first connecting hole penetrating in the z-axis direction; correspondingly, a second connecting member 213 is respectively provided at the two ends of the diameter of the chassis 2111, and a second connecting hole penetrating in the z-axis direction is provided on the second connecting portion 2114; when the outer shell 2112 and the chassis 2111 are installed, the first connecting portion 2113 and the second connecting portion 2114 are first aligned, and the first connecting hole is aligned with the second connecting hole. The first connecting member 213 passes through the first connecting hole and the second connecting hole in sequence in the z-axis direction to achieve the connection between the outer shell 2112 and the chassis 2111.

[0034] Preferably, a first positioning column 2119 is provided in the middle of the chassis 2111 , and the first positioning column 2119 and the chassis 2111 are integrated, and one end of the first positioning column 2119 away from the chassis 2111 is inserted into the power transmission coil 216 to prevent the power transmission coil 216 from moving on the surface of the chassis 2111 .

[0035] Preferably, the first positioning column 2119 is hollow in design to meet the lightweight design requirements of the chassis 2111.

[0036] In one embodiment, if Figure 2-Figure 4 As shown, the top of the outer shell 2112 is provided with an abutment platform 2115 extending inwards; The first positioning member 212 is built into one end of the base 211 and is provided with an abutting portion 2121, and the abutting portion 2121 includes an abutting surface 2122; the first positioning member 212 passes through the middle of the abutting platform 2115, and the abutting surface 2122 is in contact with the bottom surface of the abutting platform 2115; The diameter of the abutting surface 2122 is larger than the inner diameter of the first abutting portion 2121 .

[0037] Specifically, the inner wall of the top of the outer shell 2112 extends toward the center of the circle to form an annular abutment platform 2115, the abutment portion 2121 is arranged at the bottom of the first positioning member 212, the abutment surface 2122 is perpendicular to the z-axis direction, the bottom surface of the abutment platform 2115 and the abutment surface 2122 are in contact with each other, and the diameter of the abutment surface 2122 is larger than the inner diameter of the first abutment portion 2121, so as to prevent the first positioning member 212 from detaching from the base 211.

[0038] By fitting the abutting surface 2122 and the bottom surface of the abutting platform 2115, the first positioning member 212 can be effectively prevented from moving in the power supply seat 21, thereby enhancing the stability of the entire structure and avoiding misalignment caused by vibration or other external factors, thereby affecting the charging effect. Since the diameter of the abutting surface 2122 is larger than the inner diameter of the first abutting portion 2121, the first positioning member 212 is prevented from accidentally falling out of the base 211, and a good connection state can be maintained even in the case of long-term use or under the action of external force, thereby ensuring the continuity and safety of the charging process. At the same time, the precise alignment of the first positioning member 212 and the power supply seat 21 is ensured, so that the opening and closing structure 100 can be accurately aligned with the power transmission coil 216 when approaching the power supply seat 21, thereby ensuring an efficient wireless charging process. This is because during the wireless charging process, the coils at the transmitting end and the receiving end need to be aligned as much as possible to reduce energy loss and improve charging efficiency.

[0039] In one embodiment, if Figure 2-Figure 4As shown, the abutting portion 2121 further includes an inserting surface 2123 formed at the edge of the abutting surface 2122 extending toward the cavity in the z-axis direction, and the inserting surface 2123 is provided with a snap-fit ​​interface 2124; A locking member 2116 is disposed on the inner side of the outer shell 2112 close to the abutting platform 2115 . The locking member 2116 is embedded in the locking interface 2124 to fix the relative position of the first positioning member 212 and the outer shell 2112 .

[0040] Specifically, the plug-in surface 2123 is an annular structure, and its outer wall fits against the inner wall of the outer shell 2112 to prevent the first positioning member 212 from shaking in the outer shell 2112. The engaging member 2116 is at least one group, and the two engaging members 2116 in one group are respectively arranged at the two ends of a diameter of the outer shell 2112. The engaging member 2116 is a long strip structure, and its length direction is parallel to the z-axis direction, and the engaging member 2116 is integrated with the outer shell 2112.

[0041] The plug-in surface 2123 is provided with at least one group of snap-fit ​​interfaces 2124, and the two snap-fit ​​interfaces 2124 in one group are respectively arranged at the two ends of a diameter of the plug-in surface 2123. When installing the first positioning member 212 and the outer shell 2112, the end of the first positioning member 212 with a smaller diameter is passed through the top of the outer shell 2112, and the end of the snap-fit ​​member 2116 away from the abutment platform 2115 is inserted into the snap-fit ​​interface 2124 in the z-axis direction, and then the first positioning member 212 is continued to be moved in the z-axis direction, so that the snap-fit ​​member 2116 is completely embedded in the snap-fit ​​interface 2124 until the abutment surface 2122 and the bottom of the abutment platform 2115 are fitted.

[0042] Through the cooperation of the locking member 2116 and the locking interface 2124, the first positioning member 212 can be fixed in the outer shell 2112 to prevent it from loosening or falling off during use, and can remain stable during long-term use. At the same time, the plug-in surface 2123 makes the position of the first positioning member 212 in the cavity more fixed, reducing the displacement caused by external vibration or impact, and ensuring the long-term stable operation of the power supply component 2.

[0043] In one embodiment, if Figure 2-Figure 4 As shown, the power supply seat 21 also includes a first isolating member 214 and a second isolating member 215 . The first isolating member 214 is arranged between the power transmission coil 216 and the first positioning member 212 , and the second isolating member 215 is arranged between the chassis 2111 and the power transmission coil 216 .

[0044] Specifically, a second positioning column 2125 is disposed inside the first positioning member 212 . The first positioning column 2119 and the second positioning column 2125 have the same central axis, and the diameter of the first positioning column 2119 is greater than the diameter of the second positioning column 2125 .

[0045] The second positioning post 2125 is integrated with the first positioning member 212 and connected to the first positioning member 212 on the central axis of the first positioning member 212. A circular hole is provided at the center of the first isolating member 214 for the second positioning post 2125 to pass through and fix the first isolating member 214 on the first positioning member 212. The second isolating member 215 is provided with a through hole. When the second isolating member 215 is installed on the chassis 2111, the first positioning post 2119 passes through the through hole to fix the second isolating member 215 on the chassis 2111, and then the power transmission coil 216 is placed on the second isolating member 215, so that the first positioning post 2119 is inserted into the power transmission coil 216.

[0046] In one embodiment, if Figure 5-Figure 8 As shown, the wireless charging structure 200 further includes an extension fixing assembly 3, including: a mounting seat 31 and a support member 32; The mounting seat 31 is fixedly mounted on other structures, the first end 321 of the support member 32 is fixed in the mounting seat 31, and the second end 322 of the support member 32 is connected to the power supply seat 21 to support and maintain the stability of the position of the power supply seat 21.

[0047] Specifically, when the distance between the wall or other installation location and the opening and closing structure 100 on the curtain is far, if the power supply component 2 is directly installed on the wall or other installation location, the distance between the charging component and the opening and closing structure 100 will be too large, affecting the charging efficiency or making charging impossible.

[0048] The extending fixing component 3 is installed between the wall / other installation location and the power supply component 2 , and the power supply component 2 is supported so that it can be close to the opening and closing structure 100 to charge the opening and closing structure 100 .

[0049] Preferably, the mounting seat 31 includes a supporting portion 311 and a supporting connecting portion 312, the supporting connecting portion 312 is a hollow cylindrical structure, and a first rotating connecting member 313 is provided on the inner wall thereof; The support member 32 is a column structure, such as Figure 8As shown, a second rotating connector 325 is provided on one end side wall for inserting the support connection part 312. When the support member 32 is inserted into the support connection part 312, the second rotating connector 325 is inserted between the two first rotating connectors 313. Similarly, the first rotating connector 313 is inserted between the two second rotating connectors 325. The support member 32 and the support connection part 312 are connected and fixed by the first rotating connector 313 and the second rotating connector 325. At the same time, the telescopic adjustment of the support member 32 in the support connection part 312 can also be controlled to realize the installation of long and short distances between the wall and the opening and closing structure 100. When the distance between the wall and the curtain rail is long, the support member 32 is rotated and adjusted to rise in the z-axis direction to shorten the distance between the power supply component 2 and the opening and closing structure 100; otherwise, the support member 32 is rotated and adjusted to fall in the z-axis direction to make the distance between the power supply component 2 and the opening and closing structure 100 appropriate.

[0050] The support member is a disc-shaped structure. When installed, its surface fits against the wall, and the support member is fixed to the wall by screws.

[0051] When the wall is made of ceramic, the connection with the wall is achieved by sticking acrylic double-sided tape on the bottom of the support.

[0052] In one embodiment, if Figure 7 As shown, the end surface of the second end 322 is provided with a plug-in connector 323; The bottom of the power supply seat 21 is provided with an insertion port 2117 , and the plug connector 323 is inserted into the insertion port 2117 to fix the power supply seat 21 and the extension fixing assembly 3 in connection.

[0053] Specifically, the second end 322 of the support member 32 is used to connect to the bottom of the power supply socket 21 of the power supply component 2, and at least one group of connectors 323 are arranged on the end face of the second end 322. Correspondingly, a group of plug interfaces 2117 are arranged on the chassis 2111 of the power supply socket 21, and the connection between the extension fixing component 3 and the power supply component 2 is realized by inserting the connectors 323 into the plug interfaces 2117.

[0054] In one embodiment, if Figure 7 As shown, the connector 323 is provided with a convex end 324 , and the convex end 324 clamps the plug-in port 2117 to fix the connection between the connector 323 and the plug-in port 2117 .

[0055] Specifically, the end surface of the second end 322 extends along the z-axis direction to form a connector 323, and the end of the connector 323 away from the second end 322 extends in a direction relatively away from the other connector 323 to form a convex end 324. The setting of the convex end 324 can prevent the support member 32 and the chassis 2111 from separating when the power supply component 2 moves in the z-axis direction, thereby achieving a stable connection between the extended fixing component 3 and the power supply component 2.

[0056] Preferably, a convex interface for inserting the convex end 324 is provided on the chassis 2111. When the connector 323 is inserted into the chassis 2111, the convex end 324 is first aligned with the convex interface and inserted, and then the support member 32 or the power supply component 2 is selected so that the convex end 324 is away from the convex interface and clamped in the plug interface 2117, thereby realizing a stable connection between the extension fixing component 3 and the power supply component 2.

[0057] Preferably, the chassis 2111 and the support member 32 are an integrated structure.

[0058] In one embodiment, if Fig. 9 and Fig.10 As shown, the wireless charging structure 200 further includes an inductive power receiving component, including: a power receiving coil 41 and a second positioning member 42; The second positioning member 42 is disposed on the surface of the opening and closing structure 100 and is used for abutting and positioning with the first positioning member 212 in the z-axis direction; The power receiving coil 41 is disposed in the opening and closing structure 100 , and the central axis of the power receiving coil 41 and the central axis of the power transmitting coil 216 are in the same z-axis direction.

[0059] Specifically, the power receiving coil 41 is arranged inside the opening and closing structure 100, and is used to receive electromagnetic energy from the power transmitting coil 216, convert it into electrical energy, and supply power to the opening and closing structure 100; the precise alignment of the power receiving coil 41 and the power transmitting coil 216 can ensure the maximum coupling of the electromagnetic field, improve the energy transmission efficiency, and shorten the charging time.

[0060] The second positioning member 42 is arranged on the surface of the opening and closing structure 100, and is used to abut and position with the first positioning member 212 in the z-axis direction to ensure that the central axes of the power receiving coil 41 and the power transmitting coil 216 are aligned. Through the abutment positioning of the first positioning member 212 and the second positioning member 42, it is ensured that the central axes of the power receiving coil 41 and the power transmitting coil 216 are in the same z-axis direction, and high-precision alignment is achieved. This alignment can maximize the transmission efficiency of electromagnetic energy and reduce energy loss. At the same time, the abutment positioning can ensure that the opening and closing structure 100 remains stable during the charging process, avoiding the decrease in charging efficiency due to position offset.

[0061] Example 2 Please refer to Fig.10Based on the wireless charging structure 200 described in the above embodiment 1, this embodiment provides a device for controlling the opening and closing of curtains, the opening and closing device includes any one of the wireless charging structures 200 described in the above embodiment 1 and an opening and closing structure installed on the curtain rail, the opening and closing structure 100 is connected to the curtain rail through a hook, and the opening and closing structure 100 can be charged for the opening and closing structure 100 of the curtain without disassembly through the wireless charging structure 200. The wireless charging structure 200 realizes wireless charging of the opening and closing structure 100 through a power supply component 2 arranged near the rail, wherein the power supply component 2 includes a power supply seat 21 and an electric wire, and the power supply seat 21 has a power transmission coil 216 built in. The power supply magnetic field generated by the power transmission coil 216 after being energized can charge the opening and closing structure 100 without direct contact, which solves the problem of frequent disassembly and assembly of the opening and closing structure 100 for charging in the prior art, and improves the convenience and safety of use; At the same time, the power supply seat 21 ensures accurate spatial alignment with the opening and closing structure 100 through the first positioning member 212 inside the power supply seat 21, thereby ensuring an efficient wireless charging process.

[0062] According to the above technical solution, the present invention provides a method for controlling the movement of an opening and closing structure 100 on a guide rail based on magnetic field strength, the method comprising: S1: Real-time monitoring of magnetic field strength; When the opening and closing structure 100 slides on the guide rail to a certain distance away from the wireless charging structure 200, the magnetic field strength E of the opening and closing structure 100 （L） is very small and can be ignored. When the opening and closing structure 100 gradually moves closer to the opening and closing wireless charging structure 200, when the magnetic field strength E （L） When the acceleration a has a certain value, (L) Control the opening and closing structure 100 from the speed V （L） Start decelerating.

[0063] S2: Acquire the acceleration change rate according to the change of the magnetic field strength, and control the opening and closing structure 100 to move according to the changed acceleration until it stops.

[0064] When the movement of the opening and closing structure 100 requires that the distance between it and the wireless charging structure 200 is closest, the magnetic field strength E of the magnetic field in which the opening and closing structure 100 is placed is （L） The maximum is Emax, and the opening and closing structure has a speed of 100 V （L） is 0. When the speed V of the opening and closing structure 100 （L） With the magnetic field strength E （L） When the opening and closing structure 100 moves on the track and approaches the wireless charging structure 200, it is necessary to control the acceleration a of the opening and closing structure 100. （L） By controlling the acceleration a（L）随着 Magnetic field strength E （L） The change in also decreases, so that when the magnetic field strength is maximum, the acceleration is 0 and the speed is also 0.

[0065] When the magnetic field strength E reaches E max When the acceleration a (L) When it decreases to zero, the wireless charging structure 200 stops moving, and: The relationship between acceleration and magnetic field strength is as follows: (L) =a max *(1−(E (L) / E max )); The relationship between velocity and acceleration is formula 2: V (E) =∫a max *(1−(E (L) / E max ))dt As the distance decreases, the speed and acceleration gradually decrease, and finally stop smoothly, with formula three: V (L) =∫a max *(1−(E (L) / E max )dL.

[0066] The acceleration and speed are controlled by the change of magnetic field strength, and the movement of the opening and closing structure 100 is dynamically adjusted according to the change of magnetic field strength during the approach process. Compared with the traditional method, this solution not only relies on the change of distance, but also provides more real-time feedback information through the monitoring of magnetic field strength, making the movement smoother and smarter.

[0067] The acceleration gradually decreases as the magnetic field strength changes, ensuring that the opening and closing structure 100 will not collide due to excessive acceleration when approaching the wireless charging structure 200, thereby reducing mechanical impact and ensuring the safety of the device.

[0068] At the same time, the change of the magnetic flux of the power receiving coil in the opening and closing structure 100 is controlled in turn by controlling the change of acceleration, so as to avoid the large change of magnetic flux affecting the rapid fluctuation of the current on the power receiving coil. The rapid fluctuation of the current will cause the instantaneous excessive or unstable current; at the same time, excessive current fluctuation may cause current overload, thereby affecting the stability of the system; the coil moves too fast, which may cause the current to change sharply in a short time, causing current pulses, which may make the frequency of the current exceed the working range of the power transmission system, resulting in current instability, and may even affect the normal operation of the power supply circuit and the battery management system (BMS).

[0069] The present invention not only solves the problem of inconvenient charging of traditional curtain opening and closing devices, but also takes into account the ease of installation and adaptability to various types of curtain rails, providing users with an efficient, safe and easy-to-maintain wireless charging device.
