Description

Technical Field

[0001] This utility model relates to the field of floating doorplate technology, specifically a novel and creative doorplate. Background Technology

[0002] Traditional doorplates are typically made of rigid materials such as metal, acrylic, or wood, and are usually installed using screws or adhesives, directly attached to surfaces such as walls and doors. These doorplates have the following drawbacks: difficulty in repositioning after installation, inconvenience in replacement or cleaning; long-term exposure to outdoor environments can lead to fading, rusting, or dust accumulation, affecting aesthetics and increasing maintenance costs; and the static display method lacks visual appeal, failing to meet the technological and personalized demands of modern architectural decoration.

[0003] In recent years, creative levitation technology based on the principles of electromagnetic induction or permanent magnet repulsion has been gradually applied to indoor decorative devices such as floating picture frames, smart lamps, and display ornaments. Through contactless hovering design, it achieves dynamic visual effects, combining technological aesthetics with decorative value. Existing levitation creative products are mostly limited to indoor environments and primarily used for decoration or display purposes, failing to effectively integrate with the functional requirements of signage. Furthermore, miniaturized levitation devices face technical challenges in outdoor applications, including wind resistance, shock absorption, waterproofing, and long-term stability. For example, the levitation body is easily affected by external forces, leading to displacement, and the magnetic system lacks durability in complex environments. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a new and creative doorplate. This device solves the problems of inconvenience in cleaning and replacement, and insufficient durability of the magnetic system.

[0005] To solve the above problems, the following technical solutions are provided: This utility model discloses a novel and creative doorplate, comprising a base plate on which a support plate is rotatably connected. A levitation drive module is mounted on the support plate. The levitation drive module includes a coil assembly, a control center electrically connected to the coil assembly, a wireless charging transmitter embedded at the top of the control center, and a Hall sensor array for detecting magnetic field strength. The doorplate is positioned above the levitation drive module, and a levitation receiver module adapted to the levitation drive module is mounted on the lower surface of the doorplate. The levitation receiver module includes a wireless charging receiver adapted to the wireless charging transmitter and a permanent magnet that magnetically repels the coil assembly. Through magnetic interaction and electrical energy transmission between the levitation drive module and the levitation receiver module, the doorplate is levitated.

[0006] The above solution utilizes a levitation drive module and a levitation receiver module to create a non-rigid connection between the doorplate and the support plate and base plate. The doorplate can be directly removed for cleaning, pattern replacement, or functional maintenance without dismantling the fixed structure, making operation convenient. The magnetic repulsion between the coil assembly and the permanent magnet enables the doorplate to levitate, enhancing visual impact and improving its technological feel, thus meeting the decorative needs of modern smart buildings and high-end commercial scenarios. By cooperating with the wireless charging transmitter of the levitation drive module and the wireless charging receiver of the doorplate levitation receiver module, power transmission is completed while levitation is achieved, ensuring the continuous operation of the doorplate. This technological design enhances personalization and attractiveness, thereby solving the problems of inconvenient cleaning and replacement, and insufficient durability of the magnetic system.

[0007] Furthermore, the Hall sensor group includes a first Hall sensor, a second Hall sensor, and a third Hall sensor. The detection end planes of the first Hall sensor and the second Hall sensor are perpendicular to each other, and the detection end plane of the third Hall sensor is parallel to the base plate. The first Hall sensor, the second Hall sensor, and the third Hall sensor are all electrically connected to the control center.

[0008] In the above scheme, the detection end planes of the first Hall sensor and the second Hall sensor are perpendicular to each other, and are used to detect the magnetic field strength deviation of the doorplate in the X and Y axes, respectively. The detection end plane of the third Hall sensor is parallel to the base plate and is used to detect the magnetic field strength deviation of the doorplate in the Z axis. Thus, the magnetic field strength in the X, Y, and Z directions can be detected. Furthermore, the Hall sensor group is electrically connected to the control center, which can transmit the three-dimensional magnetic field detection data to the control center in real time. This allows the control center to quickly identify the direction and magnitude of the doorplate's levitation deviation and trigger the magnetic force adjustment command of the coil assembly accordingly. This significantly improves the doorplate's anti-interference capability in daily use and ensures long-term stable levitation.

[0009] Furthermore, the coil assembly includes a first coil and four cylindrical coils, the four cylindrical coils being distributed in a ring at equal intervals along the outer periphery of the Hall sensor group, and the axes of the cylindrical coils being perpendicular to the base plate; the first coil is sleeved on the outside of the cylindrical coils.

[0010] In the above scheme, by setting up the coil assembly, the first coil and the permanent magnet form a stable initial repulsive magnetic force, providing basic levitation support for the doorplate and ensuring that the doorplate can quickly detach from the support plate and enter a levitation state; the cylindrical coil can be adjusted by the control center according to the detection data of the Hall sensor group to adjust the magnetic force and direction of each coil.

[0011] Furthermore, a frame is provided between the base plate and the support plate, the frame is fixedly connected to the base plate, and a rotating module for driving the support plate to rotate is provided on the frame.

[0012] In the above solution, the doorplate rotates synchronously with the support plate by setting up a rotating module.

[0013] Furthermore, the rotating module includes a stepper motor, a lead screw, and a slider. The stepper motor is fixedly installed on one side of the frame. The output shaft of the stepper motor is fixedly connected to one end of the lead screw via a coupling. The other end of the lead screw passes through the slider and abuts against the inner wall of the frame. The lead screw and the slider are in a sliding engagement. Both ends of the frame are provided with U-shaped grooves. Both ends of the slider are fixedly provided with horizontally extending support rods. The end of the support rod away from the slider is slidably embedded in the corresponding U-shaped groove. The end of the support plate near the frame is integrally formed with an extension block. A connecting rod is rotatably connected between the support rod and the extension block. The bottom of the other end of the support plate is provided with a first boss. The bottom plate is provided with a second boss. A rotating shaft passes between the first boss and the second boss.

[0014] In the above solution, the output speed and angle are precisely controlled by setting a stepper motor, which drives the lead screw to rotate at a uniform speed, thereby converting the rotational motion into slider movement. This ensures that the slider moves at a uniform speed, and the U-shaped groove constrains the slider movement to prevent the slider from deviating as the lead screw rotates, thus ensuring the stability of the transmission and achieving precise control of the rotation angle and speed of the support plate and doorplate.

[0015] Furthermore, two optical rods are provided on both sides of the lead screw, and the two optical rods are arranged parallel to the lead screw, with both ends of the optical rods abutting against the inner wall surface of the frame.

[0016] In the above scheme, the use of a light rod is used to precisely constrain the movement of the slider.

[0017] The above solution has the following advantages: 1. This utility model presents a novel and creative doorplate. Through the arrangement of a levitation drive module and a levitation receiver module, the doorplate forms a non-rigid connection with the support plate and base plate. The doorplate can be directly removed for cleaning, pattern replacement, or functional maintenance without dismantling the fixed structure, making operation convenient. The magnetic repulsion between the coil assembly and the permanent magnet achieves levitation of the doorplate, enhancing visual impact and improving its technological feel, thus meeting the decorative needs of modern intelligent buildings and high-end commercial scenarios. The wireless charging transmitter of the levitation drive module works in conjunction with the wireless charging receiver of the doorplate levitation receiver module to achieve power transmission while maintaining levitation, ensuring continuous operation of the doorplate. This technological design enhances personalization and attractiveness.

[0018] 2. The detection planes of the first and second Hall sensors are perpendicular to each other, and are used to detect the magnetic field strength deviation of the doorplate in the X and Y axes, respectively. The detection plane of the third Hall sensor is parallel to the base plate and is used to detect the magnetic field strength deviation of the doorplate in the Z axis. Thus, the magnetic field strength in the X, Y, and Z directions can be detected. The Hall sensor group is electrically connected to the control center, which can transmit the three-dimensional magnetic field detection data to the control center in real time. This allows the control center to quickly identify the direction and magnitude of the doorplate's levitation deviation and trigger the magnetic force adjustment command of the coil assembly accordingly. This greatly improves the doorplate's anti-interference ability in daily use and ensures long-term stable levitation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In specific embodiment 1, such as Figures 1-5As shown, a novel creative doorplate 5 of this utility model includes a base plate 1, a support plate 2 rotatably connected to the base plate 1, and a levitation drive module disposed on the support plate 2. The levitation drive module includes a coil assembly, a control center 3 electrically connected to the coil assembly, a wireless charging transmitter 4 embedded in the top of the control center 3, and a Hall sensor group for detecting magnetic field strength. The doorplate 5 is disposed above the levitation drive module, and a levitation receiver module adapted to the levitation drive module is disposed on the lower end face of the doorplate 5. The levitation receiver module includes a wireless charging receiver 6 adapted to the wireless charging transmitter 4 and a permanent magnet 7 that magnetically repels the coil assembly. The levitation drive module and the levitation receiver module interact magnetically and transmit electrical energy. This design allows the signboard 5 to float. Through the suspension drive module and suspension receiver module, a non-rigid connection is formed between the signboard 5 and the support plate 2 and base plate 1. The signboard 5 can be directly removed for cleaning, pattern replacement, or functional maintenance without dismantling the fixed structure, making operation convenient. The magnetic repulsion between the coil assembly and the permanent magnet 7 achieves the levitation of the signboard 5, enhancing its visual impact and technological feel, thus meeting the decorative needs of modern smart buildings and high-end commercial scenarios. The wireless charging transmitter 4 of the suspension drive module and the wireless charging receiver 6 of the signboard 5 suspension receiver module work together to achieve power transmission while maintaining levitation, ensuring the continuous operation of the signboard 5. This technological design enhances its personalization and attractiveness.

[0022] The Hall sensor assembly includes a first Hall sensor 8, a second Hall sensor 9, and a third Hall sensor 10. The detection end planes of the first Hall sensor 8 and the second Hall sensor 9 are perpendicular to each other and are used to detect the magnetic field strength deviation of the doorplate 5 in the X-axis and Y-axis directions, respectively. The detection end plane of the third Hall sensor 10 is parallel to the base plate 1 and is used to detect the magnetic field strength deviation of the doorplate 5 in the Z-axis direction. Thus, the magnetic field strength in the X, Y, and Z directions can be detected. The first Hall sensor 8, the second Hall sensor 9, and the third Hall sensor 10 are all electrically connected to the control center 3 to transmit the three-dimensional magnetic field detection data to the control center 3 in real time. This allows the control center 3 to quickly identify the direction and magnitude of the doorplate 5's levitation deviation and trigger the magnetic force adjustment command of the coil assembly accordingly. This significantly improves the anti-interference capability of the doorplate 5 in daily use and ensures long-term stable levitation.

[0023] The coil assembly includes a first coil 11 and four cylindrical coils 12. The four cylindrical coils 12 are distributed in a ring at equal intervals along the outer periphery of the Hall sensor group, and the axes of the cylindrical coils 12 are all perpendicular to the base plate 1. Under the control of the control center 3, the magnetic force and direction of each coil can be adjusted according to the detection data of the Hall sensor group. The first coil 11 is sleeved on the outside of the cylindrical coils 12. The first coil 11 and the permanent magnet 7 form a stable initial repulsive magnetic force, which provides basic levitation support for the doorplate 5, ensuring that the doorplate 5 can quickly detach from the support plate 2 and enter the levitation state. A frame 13 is provided between the base plate 1 and the support plate 2. The frame 13 is fixedly connected to the base plate 1. A rotating module is provided on the frame 13 to drive the support plate 2 to rotate, so that the doorplate 5 rotates synchronously with the support plate 2.

[0024] The rotary module includes a stepper motor 14, a lead screw 15, and a slider 16. The stepper motor 14 is fixedly installed on one side of the frame 13. The output shaft of the stepper motor 14 is fixedly connected to one end of the lead screw 15 through a coupling. The other end of the lead screw 15 passes through the slider 16 and abuts against the inner wall of the frame 13. The lead screw 15 and the slider 16 are in a sliding fit. Both ends of the frame 13 are provided with U-shaped grooves 17. Both ends of the slider 16 are fixedly provided with horizontally extending support rods 18. The end of the support rod 18 away from the slider 16 is slidably embedded in the corresponding U-shaped groove 17. The end of the support plate 2 near the frame 13 is integrally formed with an extension block 19. A connecting rod 20 is rotatably connected between the support rod 18 and the extension block 19. The bottom of the other end of the support plate 2 is provided with a first boss 21, and the bottom plate 1 is provided with a second boss 22. A rotating shaft 23 passes between the first boss 21 and the second boss 22. The stepper motor 14 precisely controls the output speed and angle, driving the lead screw 15 to rotate at a uniform speed, thereby converting the rotational motion into the movement of the slider 16, ensuring that the slider 16 moves at a uniform speed. The U-shaped groove 17 constrains the movement of the slider 16, preventing the slider 16 from deviating as the lead screw 15 rotates, ensuring the stability of the transmission, and realizing precise control of the rotation angle and speed of the support plate 2 and the door plate 5.

[0025] In specific embodiment 2, the difference between this embodiment and embodiment 1 is that, in this embodiment, both sides of the lead screw 15 are provided with optical rods 24, and the two optical rods 24 are arranged parallel to the lead screw 15. Both ends of the optical rods 24 abut against the inner wall surface of the frame 13. The optical rods 24 are used to precisely constrain the movement of the slider 16.

[0026] First, the device is powered on. Electricity is transmitted through the wireless charging transmitter 4 to the wireless charging receiver 6 to provide power. The doorplate 5 displays content. At the same time, the first coil 11, which is powered on, generates a force that repels the permanent magnet 7, causing the doorplate 5 to rise. At this time, the first Hall sensor 8, the second Hall sensor 9, and the third Hall sensor 10 simultaneously detect the magnetic field strength in the normal direction of the three mutually perpendicular planes X, Y, and Z. The obtained data is processed by the control center 3 to adjust the magnitude of the magnetic force generated by each cylindrical coil 12, and to make real-time fine adjustments to the stable levitation of the doorplate 5. When the doorplate 5 is stably levitated and reaches the preset dwell time, the stepper motor 14 is started, which drives the lead screw 15 to rotate at a constant speed through the coupling, so that the slider 16 moves smoothly along the axial direction of the lead screw 15. The movement of the slider 16 drives the connecting rod 20 to rotate, so that the support plate 2 rotates smoothly around the pivot 23 between the first boss 21 and the second boss 22. During the rotation of the support plate 2, the levitation drive module above rotates synchronously with the doorplate 5, thereby causing the doorplate 5 to rotate at an angle.
