[0001] This utility model relates to the field of display devices, and more specifically, to a rotating mechanism and a rotating display device. Background Technology

[0002] With the development of the LED industry, image display is no longer limited to conventional static screen display, but can display images through dynamic motion. For example, by driving a motor to rotate LED light strips, controlling the working state of the LED beads on the light strips, and combining the persistence of vision (POV) effect of the human eye, multiple LED light strips can work together to form an image. When observed by the human eye, the image appears to be suspended in the air. This method is applicable to various scenarios such as shopping malls, exhibition halls, concerts, and press conferences, achieving a stunning display effect.

[0003] The inventors discovered during their research that existing rotating display devices have at least the following drawbacks:

[0004] The light strip is connected to the drive motor and is suspended in the air. The weight of the light strip is directly transmitted to the drive motor shaft. During rotation, the shaft shakes a lot, resulting in poor stability and a short service life. Utility Model Content

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] In existing technology, to achieve rotation of the LED strip 001, it is generally directly connected to the shaft of the drive motor, using the shaft to drive the LED strip 001 to rotate. During operation, the LED strip 001 is suspended in the air, and its weight is directly transmitted to the shaft of the drive motor. The shaft not only needs to transmit torque but also bears a large bending moment, which exacerbates the shaking during rotation, making it impossible to increase the shaft speed. This affects both the service life of the drive motor and the quality of the displayed image.

[0039] In view of this, the designer provides a rotating mechanism for a rotating display device, which can improve the stability and reliability of the operation process, extend the service life, and improve the quality of the displayed image.

[0040] Please refer to Figures 1-3 This embodiment provides a rotating mechanism for a rotating display device, including a base 100, a driver 200, a connecting shaft 300, a first support 400, a second support 500, and a base disk 600, wherein:

[0041] The driver 200, the first support 400 and the second support 500 are all fixed on the base 100. One end of the connecting shaft 300 is connected to the rotating shaft of the driver 200, and the other end is connected to the base disk 600. The connecting shaft 300 is rotatably connected to both the first support 400 and the second support 500.

[0042] The driver 200 is used to drive the base plate 600 to rotate via the connecting shaft 300; the base plate 600 is used to mount the light strip 001.

[0043] As described above, the working principle of the rotating mechanism of the rotating display device provided in this embodiment is as follows:

[0044] During operation, the driver 200 starts, driving the base 600 to rotate via the connecting shaft 300. The LED strip 001 on the base 600 rotates, and after it emits light, the image formed by the LED strip 001 can be observed using the persistence of vision. Since the rotating shaft of the driver 200 is connected to the base 600 via the connecting shaft 300, and the connecting shaft 300 is simultaneously connected to the first support 400 and the second support 500 mounted on the base 100, the first support 400 and the second support 500 cooperate to support and position the connecting shaft 300. When the LED strip 001 is installed on the base 600, the weight of the LED strip 001 and the base 600 is transmitted to the connecting shaft 300, and then to the first support 400 and the second support 500. The connecting shaft 300 is not easily bent under external forces, and it does not easily wobble during rotation, resulting in high overall structural stability and a long service life. Meanwhile, the bending force transmitted from the connecting shaft 300 to the rotating shaft is small, and the rotating shaft is not easily subjected to radial external forces. The rotating shaft is mainly used to transmit torque, which makes the driver 200 have a low failure rate and a long service life. The driver 200 can drive the base plate 600 to rotate faster, thereby increasing the rotation speed of the light strip 001 located on the base plate 600, which can improve the quality of the displayed image.

[0045] The following embodiments illustrate the details of the rotating mechanism of the rotating display device of this application by way of example.

[0046] Please combine Figures 1-3 In this embodiment, optionally, the rotating mechanism of the rotating display device includes a base 100, a driver 200, a connecting shaft 300, a first support base 400, a second support base 500, a base plate 600, a coupling 700, a carbon brush 800, a slip ring 810, a circuit board 820, a terminal block 830, and a wind speed detector 900.

[0047] The driver 200, first support 400, second support 500, and anemometer 900 are all fixed to the base 100. The rotating shaft of the driver 200 is connected to the connecting shaft 300 via a coupling 700. The connecting shaft 300 is rotatably connected to both the first support 400 and the second support 500. The base plate 600 is mounted on the end of the connecting shaft 300. The carbon brush 800 is fixed to the base 100, and the slip ring 810 is sleeved on the outside of the connecting shaft 300, making electrical contact with the carbon brush 800. The slip ring 810 can be electrically connected to the circuit board 820 mounted on the base plate 600 via a power cable. The terminal block 830 is mounted on the base 100 and is electrically connected to the carbon brush 800 via a power cable. The anemometer 900 is communicatively connected to the driver 200. The anemometer 900 is used to acquire the actual wind speed, and when the actual wind speed exceeds a threshold, the driver 200 can stop operating, thereby reducing the failure rate of the display device. The light strip 001 mounted on the base plate 600 can be electrically connected to the circuit board 820 to achieve power supply and signal transmission.

[0048] Optionally, the base 100 can be configured as a shell structure with an equipment cavity, in which some functional components can be located to provide rain and dust protection and extend the service life of the functional components.

[0049] It should be understood that the base 100 can be made of metal, which has high structural strength, is not easy to deform, has good support effect, and has a long service life.

[0050] Optionally, the driver 200 can be configured as a servo motor, etc. The driver 200 can be fixed to the base 100 by bolts. The rotating shaft of the driver 200 can be connected to the connecting shaft 300 via a coupling 700. After the driver 200 is started, the rotating shaft rotates, driving the connecting shaft 300 to rotate synchronously via the coupling 700. Because the servo motor is more flexible to operate and easier to control the speed of the rotating shaft, the speed of the base plate 600 and the light strip 001 can be adaptively adjusted.

[0051] Please combine Figure 3Optionally, the connecting shaft 300 is provided with a wire-passing channel for power cable routing. The power cable connecting the slip ring 810 and the circuit board 820 can be routed through the wire-passing channel, making reasonable use of the internal space of the connecting shaft 300, resulting in a reasonable power cable routing that is less prone to tangling and damage. For example, the wire-passing channel includes a first lead hole 310 and multiple second lead holes 320. The connecting shaft 300 has a first end and a second end in its axial direction. The first end is connected to the rotating shaft via a coupling 700, and the second end is connected to the base plate 600. The first lead hole 310 extends axially in the connecting shaft 300, and one end of the first lead hole 310 extends to the end face of the second end. The number of second lead holes 320 is designed as needed, for example, it can be, but is not limited to, two. One end of each second lead hole 320 is located on the outer circumferential surface of the connecting shaft 300, and the other end is connected to the first lead hole 310. Furthermore, the multiple second lead holes 320 are evenly spaced in the circumferential direction of the connecting shaft 300. When the collector ring 810 is sleeved on the outside of the connecting shaft 300, the collector ring 810 is located on the side of the second lead hole 320 away from the first lead hole 310. The power line connected to the pin of the collector ring 810 can pass through the second lead hole 320 into the first lead hole 310, and then pass out from the end of the first lead hole 310, and then be electrically connected to the circuit board 820 on the base disk 600.

[0052] Optionally, both the first support base 400 and the second support base 500 can be fixed to the base 100 by bolts, and the first support base 400 and the second support base 500 are arranged at intervals along a preset axis. A first bearing 410 is installed in the first support base 400, and a second bearing 510 is installed in the second support base 500. The connecting shaft 300 is connected to both the first bearing 410 and the second bearing 510. The connecting shaft 300 has low friction when rotating, resulting in smoother rotation. After the connecting shaft 300 is installed with the first bearing 410 and the second bearing 510, the axis of the connecting shaft 300 coincides with the preset axis.

[0053] Please combine Figures 3-5 Furthermore, two positioning plates 520 can be installed within the second support base 500. These two positioning plates 520 cooperate to clamp the second bearing 510. Sealing rings 530 are provided between the two positioning plates 520 and between each positioning plate 520 and the connecting shaft 300 to seal the second bearing 510. During operation, external rainwater or dust is less likely to reach the second bearing 510, making it less susceptible to corrosion and rust, thus extending its service life. During assembly, the second bearing 510 is located on the side of the first bearing 410 furthest from the driver 200, meaning it is closer to the base plate 600. The second bearing 510 experiences greater forces from the base plate 600 and the light strip 001. Therefore, by adding a sealing structure, the service life of the second bearing 510 is extended, providing better stable and reliable support for the connecting shaft 300.

[0054] Optionally, the second support base 500 includes an upper base 501 and a lower base 503. A first groove 502 is provided on one side of the upper base 501, and a second groove 504 is provided on one side of the lower base 503. The lower base 503 can be fixed to the base 100 by bolts, with the opening of the second groove 504 facing upwards. The upper base 501 can be fixedly connected to the lower base 503 by bolts, and the openings of the first groove 502 and the second groove 504 mate, forming an annular groove. The cross-sectional profile of the annular groove is circular, and the cross-section is a plane perpendicular to the axis of the annular groove. By setting the second support base 500 as a split structure, it is convenient to install the two positioning plates 520 and the second bearing 510. That is, before assembly, the upper seat 501 and the lower seat 503 can be separated first, and then the two positioning plates 520 can be inserted into the second groove 504 of the lower seat 503. The second groove 504 restricts the displacement of the two positioning plates 520 along the preset axis, and the sealing ring 530 between the two positioning plates 520 is clamped. Then the upper seat 501 and the lower seat 503 are connected and installed, and the two positioning plates 520 are simultaneously inserted into the first groove 502. The installation is convenient and also facilitates the subsequent disassembly and replacement of the second bearing 510.

[0055] It should be understood that, since there are sealing rings 530 between the two positioning plates 520 and between each positioning plate 520 and the connecting shaft 300, rainwater is not easily able to enter the location of the second bearing 510, the second bearing 510 is not easily corroded and damaged, and has a long service life.

[0056] Please combine Figure 3 and Figure 6Optionally, the base plate 600 has a first side and a second side in its thickness direction. A wire-passing hole 610 is provided on the base plate 600, penetrating both the first and second sides. An annular positioning groove 620 is provided on the side containing the first side, surrounding the wire-passing hole 610. During assembly, the first side is close to the connecting shaft 300. The second end of the connecting shaft 300 is inserted into the annular positioning groove 620, and screws or other structural components are used to pass through the base plate 600 from the second side and screw them onto the second end of the connecting shaft 300. The screws fix the connecting shaft 300 and the base plate 600, ensuring that they do not detach. After assembly, the end of the first lead hole 310 away from the second lead hole 320 connects to the wire-passing hole 610. Simultaneously, the circuit board 820 is fixed to the second side of the base plate 600, and the power line led from the slip ring 810 can be electrically connected to the circuit board 820 after passing through the wire-passing channel and the wire-passing hole 610. Thus, the wiring is routed internally from the connecting shaft 300 and the base plate 600, resulting in minimal exposed power lines, reduced risk of damage, low failure rate, and high operational reliability. Simultaneously, the connecting shaft 300 is inserted into the annular positioning groove 620, which positions the connecting shaft 300, leading to high assembly efficiency. Furthermore, an adhesive layer can be filled between the two connection points to improve sealing.

[0057] Meanwhile, the second side is provided with multiple mounting slots 630, which are evenly spaced around the axis of the wire hole 610. Each mounting slot 630 is used to position one light strip 001. It should be understood that the mounting slot 630 can be a rectangular slot, and the mounting slot 630 has two slot sidewalls that are opposite each other in the circumferential direction of the wire hole 610. At least one slot sidewall is provided with a first engaging portion 640, which can be a protrusion or a groove. For example, in this embodiment, both slot sidewalls are provided with a first engaging portion 640.

[0058] It should be noted that the circuit board 820 can be a rigid board, which can be fixed to the base plate 600 by glue or screws, or directly fixed to the base plate 600 by encapsulation.

[0059] Optionally, the slip ring 810 can be fixedly connected to the connecting shaft 300 via a spline or other structure. The circumferential fixation between the slip ring 810 and the connecting shaft 300 is good, preventing relative rotation and ensuring stable and reliable operation. The carbon brush 800 is in electrical contact with the slip ring 810. The carbon brush 800 can be fixed to the base 100 and connected to the terminal block 830 via a power cord. The power cord can be connected to a battery or other electrical source to provide power.

[0060] The rotating mechanism provided in this embodiment has stable and reliable torque transmission, stable and reliable base plate rotation, and stable and reliable operation.

[0061] Please combine Figure 1 , Figure 2and Figure 7 This embodiment also provides a rotating display device, which includes multiple light strips 001 and the rotating mechanism described in the above embodiment. The multiple light strips 001 are all mounted on a base plate 600, and are arranged at intervals around the circumference of the base plate 600. That is, each light strip 001 corresponds to a mounting slot 630, and the light strip 001 is snapped into the corresponding mounting slot 630, ensuring a firm and reliable connection between the multiple light strips 001 and the base plate 600.

[0062] Optionally, each LED strip 001 includes a protective sleeve 011 and multiple LED units. Each LED unit includes a PCB board 012 and multiple LED bodies 013 mounted on the PCB board 012. The LED strips 001 can be arranged sequentially along the length of the PCB board 012, with the ends of the multiple PCB boards 012 sequentially spliced ​​together. Each PCB board 012 can be fixed to the protective sleeve 011 using screws or other structural components. After splicing multiple PCB boards 012, the overall structure is longer, the radius of the displayed image is larger, and more image information can be displayed. Multiple PCB boards 012 are all supported by the protective sleeve 011, and each LED strip 001 can be an independent module, facilitating assembly and disassembly. During assembly, the protective sleeve 011 of each LED strip 001 engages with the mounting slot 630 on the base plate 600, and then the protective sleeve 011 is fixedly connected to the base plate 600 using screws or other structural components, making assembly convenient.

[0063] Optionally, the protective sleeve 011 is provided with a second snap-fit ​​part 014 on its side. The number of second snap-fit ​​parts 014 is equal to the number of first snap-fit ​​parts 640 in each assembly slot 630, and the arrangement is consistent. This allows the first snap-fit ​​part 640 to engage with the corresponding second snap-fit ​​part 014 after the protective sleeve 011 is snapped into the assembly slot 630. In this way, the screws that fasten the protective sleeve 011 and the base plate 600 are mainly subjected to axial force. The centrifugal force generated in the radial direction during the rotation of the light strip 001 is mainly transmitted to the first snap-fit ​​part 640 through the second snap-fit ​​part 014 and finally acts on the base plate 600, rather than directly on the screws. The screws are not easily subjected to radial force, are not easily damaged, and have a long service life.

[0064] It should be understood that the second latching portion 014 can be configured as a protrusion or a groove. Specifically, when the first latching portion 640 is a protrusion, the second latching portion 014 is a groove that mates with the protrusion; when the first latching portion 640 is a groove, the second latching portion 014 is a protrusion that mates with the groove.

[0065] It is worth noting that the assembly slot 630 can be a dovetail slot or a T-shaped slot, which can increase the firmness of the snap-fit ​​between the light strip 001 and the assembly slot 630.

[0066] It should be understood that, in some embodiments, to improve the electrical connection stability of adjacent PCB boards 012, a connecting piece 015 can be provided between adjacent PCB boards 012. The connecting piece 015 can be a conductive element, and it simultaneously makes electrical contact with the adjacent PCB board 012, thereby achieving electrical connection between the adjacent PCB boards 012. Furthermore, the connecting piece 015 is located between the PCB board 012 and the protective sleeve 011. When the PCB board 012 is fixed to the protective sleeve 011, the connecting piece 015 is clamped by the PCB board 012 and the protective sleeve 011. The more firmly the PCB board 012 and the protective sleeve 011 are fixed, the more stable the position of the connecting piece 015 becomes, and the less likely poor contact will occur.

[0067] The rotating display device provided in this embodiment has a stable and reliable structure and stable and reliable operation.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
