Abstract
Description
Technical Field
[0001] This utility model relates to the field of signage technology, and in particular to a circular dynamic information guidance sign. Background Technology
[0002] The transfer halls and platform ends of subway stations, forming circular or semi-circular spaces, are core areas with high passenger flow and urgent information needs. To improve wayfinding efficiency, existing technologies have developed circular signs with dynamic display functions, updating train schedules and transfer routes in real time. However, in practical applications, these signs suffer from several drawbacks due to the long-term exposed screen design, making it difficult to balance display quality, equipment protection, and cost-effectiveness. Specific problems include: The screens of existing circular dynamic signs are mostly directly exposed in public spaces, such as subway stations where people are densely populated and the air contains a high amount of dust. There are also risks of accidental touches by passengers and scratches from foreign objects. Under long-term exposure, dust and stains easily accumulate on the screen surface, affecting display clarity and potentially causing circuit malfunctions due to dust entering the screen. Furthermore, direct sunlight (such as natural light at entrances and exits) or impacts can cause glare and damage to the display module, significantly shortening the screen's lifespan and increasing the need for maintenance and replacement. Utility Model Content
[0003] The technical problem to be solved by this utility model is that the screen surface of the existing technology is prone to dust accumulation and stains. To address this, we propose a ring-shaped dynamic information guidance sign.
[0004] To achieve the above objectives, this application adopts the following technical solution: a ring-shaped dynamic information guidance sign, comprising an assembly ring plate, wherein multiple displays are mounted on the outer ring wall of the assembly ring plate, and a protective component is provided on the surface of the displays. The protective component includes multiple fixing seats, which are evenly distributed around the axis of the assembly ring plate. Each fixing seat has a through-hole on its surface, and a chain roller is sleeved in the fixing hole of the multiple fixing seats. Multiple coil springs are sleeved on the surface of the chain rollers, and the multiple coil springs are respectively placed in the fixing holes of the multiple fixing seats. A curtain is provided between adjacent fixing seats, and the curtain is wound and fixed to the surface of the chain rollers. A pull line is fixedly connected to one side of the bottom of the curtain, and a take-up roller is provided at the end of the pull line away from the curtain.
[0005] Preferably, the inner ring wall of the assembly ring plate is equipped with multiple fixing brackets.
[0006] Preferably, the outer ring wall of the assembly ring plate is provided with an assembly ring groove, and one end of the fixing seat is fixedly connected to the bottom of the inner cavity of the assembly ring groove.
[0007] Preferably, one end of the coil spring is fixedly connected to the chain roller, and the other end of the coil spring is fixedly connected to the inner wall of the fixing hole.
[0008] Preferably, the end of the pull wire away from the curtain is wound and fixed to the surface of the take-up roller.
[0009] Preferably, a servo motor is provided at one end of the take-up roller, and the output end of the servo motor is fixedly connected to the take-up roller.
[0010] Preferably, a fixing plate is sleeved and fixed on the surface of the servo motor, and one end of the fixing plate is fixedly connected to the surface of the assembly ring plate.
[0011] Preferably, the mounting bracket is located at the top of the display screen.
[0012] The technical effects and advantages of this utility model are as follows: In this utility model, the ring-shaped dynamic information guidance sign uses an assembly ring plate as its core load-bearing structure. Multiple fixing brackets are installed on its inner ring wall to ensure stable fixation in scenarios such as subway stations. Multiple display screens are mounted on the outer ring wall as carriers of dynamic information. To address the issue of exposed display screens, a protective component is incorporated. An assembly ring groove is cut into the outer ring wall of the assembly ring plate, and multiple fixing seats are fixed at one end to the bottom of the groove and evenly distributed around the ring plate's axis, laying the foundation for comprehensive protection. The surface of the fixed base is provided with a through fixed hole, and a rotatable chain roller is fitted inside the hole. A coil spring is fitted on the surface of the chain roller corresponding to the position of the fixed base. The two ends of the coil spring are connected to the chain roller and the hole wall respectively, and can store or release the winding force as the chain roller rotates. The screen between adjacent fixed bases is wrapped around the chain roller and can be rolled up and down as the chain roller rotates, and is adapted to the ring layout of the display screen. A pull cord is attached to one side of the bottom of the screen, with the other end of the cord wound around a take-up roller. The take-up roller is fixed to the output end of a servo motor, which is connected to a ring plate via a fixing plate to ensure stability. The servo motor drives the take-up roller to rotate and pull the pull cord, which can unfold the screen. When the motor stops or reverses, the coil spring releases the winding force, driving the chain roller to retract the screen, thus achieving flexible control of the screen. The unfolded screen can isolate the complex environment of public spaces, prevent dust and stains from adhering, direct sunlight from strong light and accidental touches and scratches, ensure screen clarity, prevent circuit failures, extend screen life, reduce maintenance and replacement costs, and enhance the practical value of the sign.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0016] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a ring-shaped dynamic information guidance sign, including an assembly ring plate 1. Multiple fixing brackets 103 are installed on the inner ring wall of the assembly ring plate 1, and multiple display screens 101 are installed on the outer ring wall of the assembly ring plate 1. Protective components 2 are provided on the surface of the display screens 101, and the protective components 2 include multiple fixing seats 201. An assembly ring groove 102 is formed on the outer ring wall of the assembly ring plate 1. One end of each fixing seat 201 is fixedly connected to the bottom of the inner cavity of the assembly ring groove 102. The multiple fixing seats 201 are evenly distributed around the axis of the assembly ring plate 1. The ring-shaped dynamic information guidance sign uses the assembly ring plate 1 as its core load-bearing structure. Multiple fixing brackets 103 are installed on its inner ring wall to fix the overall device, ensuring that the sign can be stably installed in the designated location in the usage scenario (such as a subway station). The outer ring wall is equipped with multiple display screens 101 for displaying dynamic information, providing a carrier for information transmission. To address the issue of exposed use of the display screen 101, a protective component 2 is specifically designed. Multiple mounting bases 201 in the protective component 2 cooperate with the assembly ring groove 102 opened on the outer ring wall of the assembly ring plate 1. One end of the mounting base 201 is firmly connected to the bottom of the inner cavity of the assembly ring groove 102, and the multiple mounting bases 201 are evenly distributed around the axis of the assembly ring plate 1. This distribution method allows the subsequent protective components to form a ring-shaped coverage, which is compatible with the ring layout of the display screen 101, laying a structural foundation for comprehensive protection of the display screen 101.
[0017] Furthermore, a through-hole 202 is provided on the surface of the fixed base 201. A chain roller 203 is sleeved in the fixing hole 202 of the multiple fixed bases 201. A multiple coil spring 204 is sleeved on the surface of the chain roller 203. The multiple coil springs 204 are respectively placed in the fixing hole 202 of the multiple fixed bases 201. One end of the coil spring 204 is fixedly connected to the chain roller 203, and the other end of the coil spring 204 is fixedly connected to the inner wall of the fixing hole 202. A curtain 205 is provided between adjacent fixed bases 201. The curtain 205 is wrapped and fixed on the surface of the chain roller 203. The chain roller 203 is sleeved in these fixing holes 202, so that the chain roller 203 can rotate with the fixed base 201 as support. Multiple coil springs 204 are also sleeved on the surface of the chain roller 203, and each coil spring 204 is placed in the corresponding fixing hole 202 of the fixing seat 201. One end of the coil spring 204 is fixedly connected to the chain roller 203, and the other end is fixedly connected to the inner wall of the fixing hole 202. This connection method allows the coil spring 204 to generate elastic deformation and store or release winding force when the chain roller 203 rotates. The screen 205 arranged between adjacent fixing seats 201 has its main body wrapped and fixed to the surface of the chain roller 203. When the chain roller 203 rotates, the screen 205 can be unfolded or rolled up with the rotation of the chain roller 203. The winding force provided by the coil spring 204 provides the power basis for the automatic winding of the screen 205. At the same time, the annular distribution and rotation characteristics of the chain roller 203 ensure that the screen 205 can be rolled up in an annular shape along the outer ring of the mounting ring plate 1, thereby adapting to the annular layout of the display screen 101.
[0018] A pull cord 206 is fixedly connected to one side of the bottom of the curtain 205. A take-up roller 207 is attached to the end of the pull cord 206 away from the curtain 205. This end of the pull cord 206 is wound and fixed to the surface of the take-up roller 207. A servo motor 208 is attached to one end of the take-up roller 207. The output end of the servo motor 208 is fixedly connected to the take-up roller 207. A fixing plate 209 is fitted and fixed to the surface of the servo motor 208, with one end of the fixing plate 209 fixedly connected to the surface of the assembly ring plate 1. The servo motor 208 serves as a power source, and its rotation directly drives the take-up roller 207 to rotate synchronously. The fixing plate 209 is also fitted and fixed to the surface of the servo motor 208, with one end of the fixing plate 209 fixedly connected to the surface of the assembly ring plate 1. This fixing plate 209 provides stable support for the servo motor 208, ensuring that it does not shift during operation. When the screen 205 needs to be unfolded, the servo motor 208 starts and drives the take-up roller 207 to rotate. During the rotation of the take-up roller 207, the pull cable 206 is wound up. Under the action of the pull cable 206, the screen 205 is gradually unfolded from the chain roller 203 until it completely covers the display screen 101. When the screen 205 needs to be retracted, the servo motor 208 stops or rotates in the reverse direction. At this time, the coil spring 204 releases the previously stored winding force, drives the chain roller 203 to rotate in the reverse direction, and rewraps the screen 205 back onto the surface of the chain roller 203. Through the power cooperation of the servo motor 208 and the coil spring 204, the flexible unfolding and retraction of the screen 205 is realized.
[0019] The deployable screen 205 provides comprehensive protection for the display screen 101. When the screen 205 is unfolded, it isolates the display screen 101 from the complex environment of the public space, preventing dust and stains from adhering to the screen surface in densely populated environments. This ensures the clarity of the screen display and prevents dust from entering the screen and causing circuit failures. The excellent protection directly extends the lifespan of the screen. The probability of screen failure and damage is greatly reduced, which not only reduces the workload of daily equipment maintenance but also avoids the high costs incurred by frequent screen replacements. This enhances the practical value of the circular dynamic signboard in terms of both economic efficiency and equipment stability.
[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
