Description

Technical Field

[0001] This utility model relates to the field of smart home device technology, specifically a magnetically powered rotary mounting structure. Background Technology

[0002] With the popularization of smart homes, smart switches, smart thermostats, central control panels and other devices have become an important part of modern buildings. At present, most of these smart panels adopt a fixed installation method, that is, the panel base is fastened to the 86-type embedded box or wall with screws, and the panel is then snapped into the base. When in use, because the traditional installation method has a fixed viewing angle after installation, the user must move to the front to get the best visual and operating experience, which is not convenient. At the same time, the installation process is cumbersome, and the existing rotatable brackets usually use internal cable connections. Long-term rotation will cause the cable to break or wear, affecting the lifespan and applicability.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent with announcement number CN208806192U, announcement date 2019-04-30) provides a smart panel scene switch, including a wireless switch and a wireless charging base box. The wireless switch, from top to bottom, includes a button, a button panel, and a button box. The button is movably connected to the button panel, and the button panel is movably connected to the button box. The button panel is equipped with a wireless communication module and a tactile switch. The wireless communication module includes a power storage module. The tactile switch is located below the button and is electrically connected to the wireless communication module. The wireless charging base box includes a base box panel and a mounting box. The base box panel is movably connected to the mounting box, and the mounting box contains a charging base integrated module. The wireless switch and the wireless charging base box are magnetically connected, avoiding wiring hassles and allowing for flexible placement and arrangement of electrical products, thus possessing practicality.

[0004] The aforementioned mechanism uses magnetic attraction to connect the switch to the back box. However, in actual use, the back box requires cable connection. Traditional back boxes are not convenient for fixing the cable position, requiring additional cable fixation. Current cable fixation methods typically use cable ties or tape, which makes disassembly inconvenient and reduces work efficiency during subsequent cable maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide a magnetically powered rotary mounting structure to solve the problem mentioned in the background art that the bottom box needs to be connected to the cable during use. However, traditional bottom boxes are not convenient for fixing the cable position when connecting the cable, which leads to the need for additional cable fixing. However, existing cable fixing usually uses cable ties or tape, which makes it inconvenient to disassemble the cable during subsequent maintenance and results in low work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetically powered rotary mounting structure, comprising a fixed base, a circular interface on the side of the fixed base, a panel body on the side of the fixed base, and a circular power supply hub matching the circular interface on the side of the panel body, a first annular magnet assembly inside the circular power supply hub, and a matching second annular magnet assembly inside the circular interface; a movable plate on the side of the second annular magnet assembly, and an elastic mechanism on one side between the second annular magnet assembly and the movable plate; a pre-drilled hole on the upper right side of the fixed base, and a limiting mechanism for fixing cables on the side of the pre-drilled hole.

[0007] Furthermore, the elastic mechanism includes a needle tube, which is disposed inside the circular interface, and the needle tip is connected to the inside of the needle tube via a return spring.

[0008] Furthermore, one end of the return spring is connected to the side of the needle tube, and the other end of the return spring is connected to the needle tip. The needle tube and the needle tip form an elastic structure through the return spring.

[0009] Furthermore, a second limiting block is provided on the side of the needle tube, and a first limiting block matching the second limiting block is provided on the side of the needle tip.

[0010] Furthermore, the limiting mechanism includes a fixing box, which is located on the side of the reserved hole. A sliding plate is installed inside the fixing box via a connecting spring, and a baffle plate is installed on the side of the sliding plate. Magnet blocks are engaged inside the baffle plate.

[0011] Furthermore, the side of the fixing box is arc-shaped, and the diameter of the arc on the side of the fixing box is the same as the diameter of the reserved hole.

[0012] Furthermore, the top and bottom of the fixed box are provided with sliding grooves, and the top and bottom of the sliding plate are fixedly connected with sliders that match the sliding grooves. The fixed box and the sliding plate are slidably connected by the sliding grooves and sliders to form a sliding structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The magnetic connection between the panel body and the fixed base allows users to easily rotate the panel body to any angle with one hand, ensuring smooth operation and free adjustment of the viewing angle. Magnetic installation eliminates the need for tools and precise alignment, significantly improving installation efficiency. The non-contact magnetic connection physically separates the high-voltage and low-voltage terminals, reducing the risk of sparks and electric shock. The low contact resistance between the spring mechanism and the ring electrode ensures stable operation. Integrating power supply, communication, fixing, and rotation functions into a compact hub eliminates the problems of physical cable entanglement and sliding friction wear, resulting in a long service life. The concave-convex fit structure provides axial positioning and radial limiting, stabilizing the rotation center and minimizing wobble.

[0015] Furthermore, the elastic mechanism is compressed and maintains contact with the concentric ring electrodes when the panel body and the fixed base are docked. At the same time, the first ring magnet group and the second ring magnet group are tightly attracted to each other, firmly fixing the panel body. When the user needs to adjust the viewing angle, he / she only needs to gently flick the edge of the panel with his / her finger, and the panel can rotate 360 ​​degrees around the circular power supply hub to overcome the small friction force generated by the magnetic force.

[0016] Furthermore, the internal elastic mechanism can flexibly adjust the position of the needle through the elastic force of the return spring, so that when the movable plate is squeezed, it can apply pressure to the needle, causing the return spring at the needle end to be stressed and shorten its length. Utilizing the elastic force of the needle, the circular power supply hub and the movable plate can always maintain contact.

[0017] 2. The cable's diameter allows it to press against the baffle, causing the cable's edges to conform to the curved shape of the fixing box, thus restricting the cable's position. Simultaneously, the connecting spring's elasticity assists the baffle in conforming and restricting the edges of different cables, effectively preventing cable misalignment.

[0018] Furthermore, during the movement of the sliding plate inside the fixed box, the sliding groove and slider enable the sliding plate to move more smoothly, effectively preventing the baffle from getting stuck during movement and improving the flexibility of the baffle during use. At the same time, when not in use, the reserved hole can be attracted and attached by the magnet block set on the inside of the baffle, effectively preventing dust from entering the interior of the fixed base when the reserved hole is not in use.

[0026] 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.

[0027] Example 1: As Figure 1 - Figure 4 and Figure 6The technical solution shown addresses the problem that repeated twisting during the docking of the panel body 1 and the fixed base 3 may result in insufficient tightness in their alignment. This magnetically powered rotary mounting structure discloses an elastic mechanism, including a fixed base 3. A circular interface 4 is provided on the side of the fixed base 3. The panel body 1 is positioned on the side of the fixed base 3, and a circular power supply hub 2 matching the circular interface 4 is also provided on the side of the panel body 1. A first annular magnet group 5 is disposed inside the circular power supply hub 2, and a matching second annular magnet group 6 is disposed inside the circular interface 4. A movable plate 8 is provided on the side of the magnet assembly 6, and an elastic mechanism is provided on one side between the second annular magnet assembly 6 and the movable plate 8; the elastic mechanism includes a needle tube 9, which is located inside the circular interface 4, and a needle head 11 is connected to the inside of the needle tube 9 through a return spring 10; one end of the return spring 10 is connected to the side of the needle tube 9, and the other end of the return spring 10 is connected to the needle head 11, and the needle tube 9 and the needle head 11 form an elastic structure through the return spring 10; a second limiting block 13 is provided on the side of the needle tube 9, and a first limiting block 12 matching the second limiting block 13 is provided on the side of the needle head 11.

[0028] In this example, at least two power supply electrodes arranged in concentric rings are provided on the end face of the panel body 1. The power supply electrodes are three concentric copper rings, defined as a positive ring, a negative ring, and a grounding / data communication ring, respectively; Figure 1 As shown, first, power on the mounting base 3 and fix it to the wall. Then, roughly align the circular power supply hub 2 on the back of the panel body 1 with the circular interface 4 on the base. Under the strong magnetic force, the panel will be automatically attracted and aligned, thus completing the adsorption. At this time, the elastic mechanism is compressed and maintains contact with the concentric ring electrodes when the panel body 1 and the mounting base 3 are connected. At the same time, the first ring magnet group 5 and the second ring magnet group 6 are tightly attracted, firmly fixing the panel body 1. When the user needs to adjust the viewing angle, they only need to gently flick the edge of the panel with their finger, and the panel can rotate 360 ​​degrees around the circular power supply hub 2 to overcome the small friction generated by the magnetic force. During this process, the spring mechanism is always in motion. Sliding on the smooth concentric ring electrode, the electrical connection is maintained continuously, thereby achieving uninterrupted power supply and signal transmission; the internal elastic mechanism can flexibly adjust the position of the needle 11 through the elastic force of the return spring 10, so that when the movable plate 8 is squeezed, it can apply pressure to the needle 11, so that the return spring 10 at the end of the needle 11 is stressed and shortens its length. Utilizing the elastic force of the needle 11, the circular power supply hub 2 and the movable plate 8 can always maintain a contact state. At the same time, the mutual locking of the first limit block 12 and the second limit block 13 ensures that the needle 11 will not be dislodged during the movement inside the needle tube 9, thereby effectively avoiding the problem of damage to the return spring 10 due to the extreme stroke.

[0029] Example 2: Figure 1 , Figure 2 and Figure 5 The technical solution shown addresses the problem of traditional junction boxes making it inconvenient to fix cables in place, requiring additional cable securing. Existing methods for securing cables typically use cable ties or tape, leading to inconvenience and low efficiency during subsequent cable maintenance. This magnetically powered rotary mounting structure discloses a limiting mechanism. A pre-drilled hole 7 is provided at the upper right side of the fixing base 3, and a limiting mechanism for fixing the cable is provided on the side of the pre-drilled hole 7. The limiting mechanism includes a fixing box 14, which is positioned within the pre-drilled hole 7. On the side, a sliding plate 16 is installed inside the fixed box 14 via a connecting spring 15, and a baffle plate 17 is installed on the side of the sliding plate 16. Magnet blocks 18 are snapped into the inside of the baffle plate 17. The side of the fixed box 14 is arc-shaped, and the diameter of the arc of the side of the fixed box 14 is the same as the diameter of the reserved hole 7. The top and bottom of the fixed box 14 are provided with sliding grooves 19, and the top and bottom of the sliding plate 16 are fixedly connected with sliders 20 that match the sliding grooves 19. The fixed box 14 and the sliding plate 16 are slidably connected through the sliding grooves 19 and the sliders 20 to form a sliding structure.

[0030] In this example, when installing the mounting base 3, a cable needs to be connected. The cable passes through the pre-drilled hole 7 and connects to the internal circuitry of the mounting base 3. During connection, a limiting mechanism can restrict and fix the cable's position. The cable passes through the baffle plate 17, and its diameter compresses the baffle plate 17, causing the cable's edge to conform to the arc shape of the mounting box 14, thus restricting the cable's position. Simultaneously, the elasticity of the connecting spring 15 assists the baffle plate 17 in conforming and restricting the edges of different cables, effectively preventing cable misalignment. Figure 5 As shown, during the movement of the sliding plate 16 inside the fixed box 14, the sliding groove 19 and the slider 20 enable the sliding plate 16 to move more smoothly, effectively preventing the baffle plate 17 from getting stuck during movement and improving the flexibility of the baffle plate 17 during use. At the same time, when the reserved hole 7 is not in use, it can be attracted and attached by the magnet block 18 set on the inside of the baffle plate 17, effectively preventing dust from entering the interior of the fixed base 3 when the reserved hole 7 is not in use.
