Description

Technical Field

[0001] This invention relates to the field of automated production technology, and in particular to a rotating information display device. Background Technology

[0002] Information display devices are tools used for displaying information. Common information display devices include billboards, signs, and roll-up banners. Most existing information display devices can only display a single page of information. When displaying multiple pages of information, each page requires a separate display device, which takes up a lot of space.

[0003] Existing technologies also include rotating display devices, such as water signs that can rotate 180° on both sides, driving a roller system to cyclically display multiple advertisements on a long ribbon, and scrolling billboards. However, existing rotating display devices have the following limitations: 1. Water signs that rotate on both sides can only display information on the front and back, failing to meet the needs of displaying multiple information. 2. Scrolling billboards are large outdoor advertising display devices. Due to the weight of the equipment and the complexity of ribbon replacement, the advertising content is not frequently changed (advertising contracts are long-term), and they are generally installed in fixed positions. They are difficult to use for displaying tabletop information such as water signs, roll-up banners, nameplates, and menus, and are limited by the length of the ribbon, generally only able to display 2-4 advertisements. Summary of the Invention

[0004] To address the problems existing in the background art, the present invention provides a rotating information display device, comprising: a support frame, a display board hanging cylinder rotatably connected to the support frame, a plurality of display boards hanging on the display board hanging cylinder, and the display board hanging cylinder being driven to rotate by a driving device.

[0005] The support frame includes a base with at least two support seats. A display board hanging cylinder is rotatably mounted between two adjacent support seats. Each support seat with the display board hanging cylinder is equipped with a connecting seat at its top. The connecting seat has a display board stop bar above the display board hanging cylinder to restrict the rotation of the display board.

[0006] The display board hanging cylinder includes a central rotating shaft rotatably connected to a support base. The central rotating shaft has display board hanging plates symmetrically arranged along its cross-sectional direction on both sides near the support base. Each of the two display board hanging plates has several mounting holes arranged around its surface at the same location.

[0007] Furthermore, the display panel includes a mounting shaft and at least two clips. Both the mounting shaft and the at least two clips are made of an elastomeric material.

[0008] Furthermore, the driving device includes: a direct drive device for the drive motor or an indirect drive device for the drive motor.

[0009] Furthermore, the direct-drive drive device for the drive motor includes: an external drive device and an internal drive device, wherein:

[0010] The externally driven drive device includes: a drive motor, the drive output end of which is fixedly connected to a central rotating shaft, and the housing of the drive motor being fixedly connected to a support base. The drive motor is controlled to rotate by a microprocessor.

[0011] The internal drive device includes a dual-axis drive motor. The central rotating shaft is divided into two sections and fixedly connected to a support base. The two output shafts of the dual-axis drive motor are each fixedly connected to one section of the central rotating shaft. The two display board mounting plates are rotatably connected to the output shafts and / or the central rotating shaft, and both display board mounting plates are fixedly connected to the housing of the dual-axis drive motor.

[0012] Furthermore, the indirect drive type drive device includes: a first turntable fixedly connected to the central rotating shaft, and a second turntable fixedly connected to the drive output shaft of the drive motor. The first and second turntables are configured with a wheel diameter ratio as needed, and the first and second turntables are connected by a connecting rod, belt, toothed belt, or gear set. The drive motor is controlled by a microprocessor to rotate.

[0013] Furthermore, the drive output shaft of the drive motor is connected to the outside via a transmission disk, and a permanent magnet is provided on the inner side of the transmission disk. A magnetic sensor is provided at a specific position on the placement base. The signal output terminal of the magnetic sensor is connected to the signal input terminal of the microprocessor, and the signal output terminal of the microprocessor is connected to the control command input terminal of the drive motor.

[0014] Furthermore, a control module is provided on the placement base between the two support seats. The control module contains a microprocessor, a controller, and a power supply. One signal input terminal of the microprocessor is connected to the signal output terminal of the controller.

[0015] The controller includes a time control module and a speed control module. The time control module sends duration information to the microprocessor based on input information. The speed control module sends speed information to the microprocessor based on input information. The microprocessor sends control signals to the drive motor based on the received duration and speed information.

[0016] The power source is electrically connected to the drive motor, microprocessor, and controller, and provides electrical energy.

[0017] Furthermore, the time control module includes: a first button input device, a first microcontroller, and a first LED display.

[0020] The advantages of this invention are: it is lightweight and convenient, and can display a large number of adjustable amounts of information as needed. Furthermore, it can be used not only for outdoor advertising displays but also for desktop information displays, making it widely applicable. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0032] Example 1

[0033] A rotating information display device, such as Figure 1 As shown, it includes: a support frame 1, on which a display board hanging cylinder 3 is rotatably connected, and several display boards 2 are hung on the display board hanging cylinder 3. The display board hanging cylinder 3 is driven to rotate by a driving device.

[0034] The support frame 1 includes a base 104, on which two, three, or a number of support seats 101 are provided, and a display board hanging cylinder 3 is rotatably installed between two adjacent support seats 101. Each support seat 101 on which the display board hanging cylinder 3 is rotatably installed is provided with a connecting seat 102 at its top, and the connecting seat 102 is provided with a display board stop bar 103 above the display board hanging cylinder 3 to restrict the rotation of the display board 2.

[0035] The display board stop bar 103 is positioned near the edge of the horizontal axis of the display board hanging cylinder 3 along the rotation direction of the display board hanging cylinder 3, and its height is near the top of the display board 2 after it is attached.

[0036] The display board hanging cylinder 3 includes a central rotating shaft 301 rotatably connected to the support base 101. The central rotating shaft 301 has display board hanging plates 302 symmetrically arranged along the cross-sectional direction on both sides near the support base 101. Each of the two display board hanging plates 302 has several mounting holes arranged around its surface at the same position.

[0037] The procedure for using this device is as follows: First, install the information page to be displayed inside the display board 2. Then, hang the display board 2 with the information page installed on it on the display board hanging cylinder 3. Next, place the information display device on the desktop or outdoors where the information needs to be displayed, and start the drive mechanism. At this time, the drive mechanism will cause the display board hanging cylinder 3 to rotate, for example... Figure 1 In this process, the drive device rotates the display board hanging cylinder 3 counterclockwise, which in turn causes the display board 2 to rotate along the central axis 301. When the display board 2 rotates to the position of the display board stop bar 103, it is prevented from falling due to its own weight by the stop bar 103, thus displaying the front information to the user. As the display board 2 continues to rotate, and its upper end falls below the stop bar 103, the display board 2 quickly falls back to the previous display board 2 due to rotational inertia and its own weight, at which point the back information of the display board 2 is displayed to the user. This cycle repeats, completing the display of multiple pieces of information.

[0038] The rotating information display device of this invention can be equipped with display card hanging cylinders 3 of corresponding sizes to hang the required number of display cards 2. Each display card 2 can display two pieces of information, one on the front and one on the back. Different information can be displayed separately as needed, or a paginated arrangement can be used so that the two display cards 2 located above and below each other in the display position display one page of information, which can then be combined to obtain a larger display of information.

[0039] Example 2

[0040] The information display device based on the rotating display of Embodiment 1, such as Figure 2 As shown, the display panel 2 includes a mounting shaft 201 and two clamping pieces 202. Both the mounting shaft 201 and the two clamping pieces 202 are made of an elastomeric material. With this design, when the display panel 2 needs to be replaced, pressing the mounting shaft 201 and the two clamping pieces 202 causes them to bend, disengaging the mounting shaft 201 from the mounting hole, thus removing the display panel 2. Then, pressing and bending the display panel 2 to be installed causes the mounting shaft 201 to be pre-inserted into the mounting hole. Releasing the handle allows the display panel 2 to return to its unfolded state under its own elastic force, at which point the mounting shaft 201 is fully inserted into the mounting hole, completing the installation of the display panel 2.

[0041] At this time, you can choose from the following options as needed: Figure 3 As shown, several hidden buckles 203 are provided at the edges of the two clips 202 away from the mounting shaft 201, which serves to detachably fix the two clips 202, so that the information page between the clips 202 can be clamped more securely.

[0042] Example 3

[0043] The information display device based on the rotating display of Embodiment 1, such as Figure 1 and Figure 4 As shown, the driving device includes: a first turntable 4 fixedly connected to the central rotating shaft 301, and a second turntable 5 fixedly connected to the drive output shaft of the drive motor 8. The first turntable 4 and the second turntable 5 are configured with a wheel diameter ratio (e.g., 1:1) as needed, and both are equipped with wheel teeth. The first turntable 4 and the second turntable 5 are connected by a matching toothed belt 6. The drive motor 8 is controlled to rotate by a microprocessor 11.

[0044] At this time, the drive motor 8 drives the second turntable 5 to rotate, and the second turntable 5 drives the first turntable 4 to rotate via the toothed belt 6, which in turn drives the central rotating shaft 301 to rotate, and finally drives the display board 2 to rotate via the display board hanging plate 302. The drive motor 8 can be a stepper motor as needed.

[0045] Example 4

[0046] The information display device based on the rotating display of Embodiment 1, such as Figure 5 As shown, the driving device includes a drive motor 8, the drive output end of which is fixedly connected to the central rotating shaft 301, and the housing of the drive motor 8 is fixedly connected to the support base 101. The drive motor 8 is controlled to rotate by a microprocessor 11.

[0047] At this time, the drive motor 8 is externally fixed and its rotation is restricted by the support base 101. The drive motor 8 is controlled by the drive output end to drive the central rotating shaft 301 to rotate, which in turn drives the display board hanging plate 302 to rotate, and finally drives the display board 2 to rotate. The drive motor 8 can be a stepper motor as needed.

[0048] Example 5

[0049] Based on the rotating information display device of Embodiment 1, the driving device includes: a first turntable 4 fixedly connected to a central rotating shaft 301, and a second turntable 5 fixedly connected to the drive output shaft of a drive motor 8. The first turntable 4 and the second turntable 5 are configured with a wheel diameter ratio (e.g., 1:1) as needed, and are connected by a gear set with a transmission ratio (e.g., 1:1) as needed. The drive motor 8 is controlled to rotate by a microprocessor 11.

[0050] At this time, the drive motor 8 drives the second turntable 5 to rotate, and the second turntable 5 drives the first turntable 4 to rotate through the gear set, which in turn drives the central shaft 301 to rotate, and finally drives the display board 2 to rotate through the display board hanging plate 302. The drive motor 8 can be a stepper motor as needed.

[0051] Example 6

[0052] Based on the rotating information display device of Embodiment 1, the driving device includes: a first turntable 4 fixedly connected to a central rotating shaft 301, and a second turntable 5 fixedly connected to the drive output shaft of a drive motor 8. Rotational mounting shafts are provided at the same positions on the first turntable 4 and the second turntable 5, and a linkage transmission connection is established between the first turntable 4 and the second turntable 5, which is rotatably connected to the rotational mounting shafts. The drive motor 8 is controlled to rotate by a microprocessor 11.

[0053] At this time, the drive motor 8 drives the second turntable 5 to rotate, and the second turntable 5 drives the first turntable 4 to rotate through the connecting rod, which in turn drives the central rotating shaft 301 to rotate, and finally drives the display board 2 to rotate through the display board hanging plate 302. The drive motor 8 can be a stepper motor as needed.

[0054] Example 7

[0055] The information display device based on the rotating display of Embodiment 1, such as Figure 6 As shown, the driving device includes: a dual-axis drive motor 8; the central rotating shaft 301 is divided into two sections and fixedly connected to the support base 101 respectively; the two output shafts 801 of the dual-axis drive motor 8 are fixedly connected to one section of the central rotating shaft 301 respectively. The two display board hanging plates 302 are rotatably connected to the output shafts 801 and / or the central rotating shafts 301 respectively, and both display board hanging plates 302 are fixedly connected to the housing 802 of the dual-axis drive motor 8.

[0056] At this time, the two output shafts 801 of the drive motor 8 are fixed to the support base 101 via the central rotating shaft 301. Therefore, when the drive motor 8 is rotated under control, it no longer drives the output shafts 801 to rotate, but rather the outer casing 802 rotates along the output shafts 801, thereby driving the display board hanging plate 302 fixed to the outer casing 802 to rotate, and finally driving the display board 2 to rotate through the display board hanging plate 302. The drive motor 8 can be a stepper motor as needed.

[0057] Example 8

[0058] Based on any of the rotating information display devices in Embodiments 3-7, such as Figure 7 and Figure 8 As shown, the drive output shaft of the drive motor 8 is connected to the outside via a transmission disk 9, and a permanent magnet 901 is provided on the inner side of the transmission disk 9. A magnetic sensor 10 is provided at a specific position on the placement base 104. The signal output terminal of the magnetic sensor 10 is connected to the signal input terminal of the microprocessor 11, and the signal output terminal of the microprocessor 11 is connected to the control command input terminal of the drive motor 8.

[0059] Since the information display device of the present invention needs to rely on the fixed point, fixed speed and fixed time rotation of the driving device to complete the display, stay and rotate of the information page, the fixed time and fixed speed can be obtained by controlling the stepper motor according to the control program, and the fixed point is an important control node that determines whether the display page can be effectively displayed in the target display position.

[0060] By setting up a permanent magnet 901 and a magnetic sensor 10, the present invention first controls the drive motor 8 to drive the transmission disk 9 to rotate when the device is started. When the magnetic sensor 10 senses the permanent magnet 901, it means that the device is in the initial position. Then, by performing constant speed and time control, the display board 2 can be effectively stopped at the target position for display.

[0061] Example 9

[0062] The information display device based on the rotating display of Embodiment 8, such as Figure 7 As shown, a control module 7 is provided on the placement base 104 between two support bases 101. The control module 7 includes a microprocessor 11, a controller 12, and a power supply. One signal input terminal of the microprocessor 11 is connected to the signal output terminal of the controller 12.

[0063] The controller 12 includes a time control module and a speed control module. The time control module sends duration information to the microprocessor 11 based on input information. The speed control module sends speed information to the microprocessor 11 based on input information. The microprocessor 11 sends control signals to the drive motor 8 based on the received duration and speed information.

[0064] The power source is electrically connected to the drive motor 8, microprocessor 11, and controller 12, and provides them with electrical energy.

[0065] As needed, the time control module can be a control module composed of a key input device, a microcontroller, and an LED display. The key input device inputs adjustment information to the microcontroller through a circuit board, and the LED display displays the current control command information of the microcontroller in real time through the circuit board. After receiving the adjustment command from the key input device, the microcontroller makes corresponding increases or decreases based on the current control command to obtain new control command information, and sends it to the microprocessor 11.

[0066] For example, if the current control command recorded by the microcontroller is 2.00 seconds, after receiving this information, the microprocessor 11 will control the drive motor 8 to rotate by a preset angle and then pause for 2 seconds each time. The preset rotation angle R = 360 / M, where M is the number of display boards 2 hung at equal intervals on the display board hanging cylinder 3. When the keypad input device adds a time unit, the control command recorded by the microcontroller becomes 2.10 seconds. At this time, after receiving this information, the microprocessor 11 will control the drive motor 8 to rotate by a preset angle and then pause for 2.1 seconds each time.

[0067] According to the design, the speed control module can be a control module composed of a key input device, a microcontroller, and an LED display. The key input device inputs adjustment information to the microcontroller through a circuit board, and the LED display displays the current control command information of the microcontroller in real time through the circuit board. After receiving the adjustment command from the key input device, the microcontroller increases or decreases the current control command to obtain a new control command information, which is then sent to the microprocessor 11.

[0068] For example, if the current control command recorded by the microcontroller is 2.00 seconds, after receiving this information, the microprocessor 11 controls the drive motor 8 to rotate by a preset angle within 2 seconds. The preset angle R = 360 / M, where M is the number of display boards 2 evenly spaced on the display board hanging cylinder 3. When the keypad input device adds a time unit, the control command recorded by the microcontroller becomes 2.10 seconds. At this time, after receiving this information, the microprocessor 11 controls the drive motor 8 to rotate by a preset angle within 2.1 seconds each time, meaning the rotation speed slows down.

[0069] The above settings allow the information display device of the present invention to flexibly adjust the information display time and information update frequency according to customer needs, so as to obtain the best information display effect.

[0070] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
