Abstract
Description
Technical Field
[0001] This application relates to the field of lifting screen technology, specifically to an arch bridge curtain-type lifting screen mechanism. Background Technology
[0002] With the acceleration of urbanization and the increasing demands for efficient use of urban space, traditional advertising and information dissemination methods are no longer sufficient to meet the needs of modern cities. Arch bridges, as a common urban infrastructure, possess unique structural and spatial advantages, often with a large amount of unused space beneath and around them. To fully utilize these spaces, enhance the technological and modern feel of the urban landscape, and simultaneously meet diverse needs such as large-scale outdoor performances, advertising, and public information dissemination, installing screens on arch bridges has become an innovative solution.
[0003] Most existing screens are fixedly installed on arch bridges (i.e., fixed application scenarios), such as Figure 1 As shown, this installation method has many limitations: First, the screen occupies a large amount of vertical space, resulting in low utilization of the space under the bridge; second, the display area is fixed and rigid, making it impossible to flexibly adjust the display content or layout according to actual conditions; furthermore, the screen cannot move freely, lacking dynamic combination modes, making it difficult to achieve flexible and diverse displays. Therefore, this fixed installation method has significant limitations in application scenarios and cannot meet diverse needs. Utility Model Content
[0004] Therefore, this application provides an arch bridge curtain-type lifting screen mechanism to solve the problems of poor space utilization, inability to move freely, and limited space in the existing technology.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] An arch bridge-style curtain-type lifting screen mechanism includes an arch bridge, multiple roller mechanisms, and multiple curtain screens. Multiple spaced-apart support plates are fixedly arranged at intervals along the length of the upper side of the arch bridge. The multiple roller mechanisms are respectively fixedly arranged on the multiple spaced-apart support plates. Each curtain screen is located between two spaced-apart support plates, and both ends of each curtain screen are fixedly connected to the spaced-apart support plates on both sides via two roller mechanisms. Each roller mechanism includes a roller, a motor reducer, and a pull cable. The roller and the motor reducer are fixedly arranged on the spaced-apart support plates. The output end of the motor reducer is mechanically connected to the roller. One end of the pull cable is fixed to the roller, and the other end is fixedly connected to one end of the curtain screen. A support roller is arranged between every two spaced-apart support plates. The support roller is fixedly arranged on the upper side of the arch bridge by a bracket and contacts the curtain screen. The support roller is used to guide the curtain screen to unfold or roll up.
[0007] Preferably, the output end of the motor reducer is connected and fixed to the drum via a connecting shaft and a flange.
[0008] Preferably, the device also includes a stroke detection device, which is fixedly disposed at the end of the drum.
[0009] Preferably, the stroke detection device is fixedly mounted at the end of the drum via a connecting shaft and a flange.
[0010] Preferably, a fixing screen is also included, which is disposed above the curtain screen and fixed to the side of the arch bridge.
[0011] Preferably, the curtain screen is a flexible OLED screen.
[0012] Compared with the prior art, this application has at least the following beneficial effects:
[0013] 1. This application provides an arch bridge curtain-type lifting screen mechanism, including an arch bridge, multiple roller mechanisms, and multiple curtain screens. Multiple spaced-apart support plates are fixedly arranged along the length of the upper side of the arch bridge. The roller mechanisms are fixedly mounted on the spaced-apart support plates. The curtain screens are located between two spaced-apart support plates and are fixedly connected to the spaced-apart support plates via the roller mechanisms. The roller mechanism includes a roller, a motor reducer, and a cable. The roller and motor reducer are fixedly mounted on the spaced-apart support plates. The output end of the motor reducer is mechanically connected to the roller. One end of the cable is fixed to the roller, and the other end is fixedly connected to the curtain screen. A roller is provided between every two spaced-apart support plates. The roller is fixedly mounted on the upper side of the arch bridge via a bracket and contacts the curtain screen. The roller guides the curtain screen to unfold or roll up. The arch bridge curtain-type lifting screen mechanism provided in this application uses roller mechanisms instead of commonly used fixed brackets or hanging mechanisms. Multiple roller mechanisms can control the unfolding or rolling up of screens in different areas. Each drive can move independently, forming different display spaces, improving space utilization, and allowing for free movement without space restrictions.
[0014] 2. The arch bridge curtain-type lifting screen mechanism provided in this application also includes a stroke detection device. The stroke detection device can determine the relative position of the curtain screen by detecting the rotation of the roller. Based on the position and speed signal feedback of each level of the curtain screen, the relative motion synchronization of multiple levels of curtain screens can be realized, and it supports various position spatial combination changes.

[0024] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.
[0025] Please see Figure 2 and Figure 3 This application provides an arch bridge curtain-type lifting screen mechanism for multi-level lifting screen display on an arch bridge. It includes an arch bridge 1, multiple roller mechanisms 3, and multiple curtain screens 4. Multiple spaced-apart support plates 2 are fixedly installed along the length of the upper side of the arch bridge 1. Multiple roller mechanisms 3 are respectively fixedly installed on the multiple spaced-apart support plates 2. Each curtain screen 4 is located between two spaced-apart support plates 2, and its two ends are fixedly connected to the spaced-apart support plates 2 on both sides through two roller mechanisms 3. The arch bridge curtain-type lifting screen mechanism provided in this application uses roller mechanisms 3 instead of commonly used fixed brackets or hanging mechanisms. Multiple roller mechanisms 3 can control the unfolding or rolling up of screens in different areas. Each curtain screen 4 can move independently, forming different display spaces, improving space utilization, and allowing for free movement without space restrictions.
[0026] Please see Figure 4The rolling mechanism 3 includes a rolling drum 301, a motor reducer 302, and a cable 303. The rolling drum 301 and the motor reducer 302 are fixedly mounted on the spaced-apart support plates 2. The output end of the motor reducer 302 is mechanically connected to the rolling drum 301. One end of the cable 303 is fixed to the rolling drum 301, and the other end is fixedly connected to one end of the curtain screen 4. A roller 5 is provided between every two spaced-apart support plates 2. The roller 5 is fixedly mounted on the upper side of the arch bridge 1 through a bracket 6 and contacts the curtain screen 4. The roller 5 is used to guide the curtain screen 4 to unfold or roll up. The arch bridge curtain-type lifting screen mechanism provided in this application uses a motor reducer 302 to drive the rolling drum 301, thereby controlling the curtain screen 4 to roll up or unfold. The curtain screen 4 occupies less space when retracted, which can make full use of existing building space.
[0027] It should be noted that the heights of the various arches of arch bridge 1 are inconsistent (e.g., Figure 2 As shown, the two middle arches are higher, while the arches on the sides are lower. Figure 3 The height of the drum mechanism 3 shown in the image is inconsistent; while Figure 4 To illustrate the detailed structure of the roller mechanism 3, we will take the control of a curtain screen 4 as an example. The two roller mechanisms 3 at both ends of the curtain screen 4 are overlapped when viewed from the side (that is, the installation positions of the bridge-hole roller mechanisms 3 at the same height on the spaced support plates 2 are the same), so that the curtain screen 4 can be evenly stressed at both ends when it is unfolded or rolled up.
[0028] In the arched curtain-type lifting screen mechanism provided in this application, the roller drum 301 is fixed to the spaced mounting support plate 2 by a bracket; the output end of the motor reducer 302 is connected and fixed to the roller drum 301 through a connecting shaft and a flange. In this application, the motor reducer 302 drives the roller drum 301 to rotate, thereby driving the pull cable 303 to achieve lifting and rolling of the curtain screen 4.
[0029] The arch bridge-style curtain-type lifting screen mechanism provided in this application also includes a stroke detection device 8, which is fixedly installed at the end of the drum 301. The stroke detection device 8 is fixedly installed at the end of the drum 301 via a connecting shaft and a flange. Installing the stroke detection device 8 on the drum 301 allows for real-time positioning of the status of different curtain-type screens, and the feedback signals can be used to detect and adjust the raising and lowering speed and position of each curtain screen 4 at any time. In this application, the stroke detection device 8 can determine the relative position of the curtain screen 4 by detecting the rotation of the drum 301. Based on the position and speed signals of each level of curtain screen 4, the relative movement synchronization of multiple levels of curtain screen 4 can be achieved, and various positional spatial combinations can be supported.
[0030] The arch bridge curtain-type lifting screen mechanism provided in this application also includes a fixed screen 7, which is disposed above the curtain screen 4 and fixed to the side of the arch bridge 1 by an L-shaped bracket.
[0031] In the arched curtain-type lifting screen mechanism provided in this application, the curtain screen 4 is a flexible OLED screen. The flexible OLED screen possesses excellent flexibility, easily enabling rolling and folding operations, perfectly adapting to the usage scenarios of the curtain screen 4, making it more convenient to store and unfold. Simultaneously, the OLED screen, with its self-emissive characteristics, provides superior contrast and color performance, capable of presenting more vivid and realistic image effects. Furthermore, the flexible OLED screen is also lightweight and thin, significantly reducing the overall weight of the curtain screen 4, facilitating installation and use.
[0032] This application provides an arched curtain-type lifting screen mechanism that uses a roller mechanism 3 instead of the commonly used fixed bracket or hanging mechanism. It employs multi-stage drive to unfold or roll up the screen in different areas, with each stage capable of independent movement to create different display spaces. Simultaneously, there is mutual positioning detection and locking between the various drive stages, achieving synchronized movement and fixed relative positions under different conditions. This enables diverse presentations while maintaining accurate positioning. The flexible and adaptable spatial configuration allows the arched curtain-type lifting screen mechanism to be applied to various functional locations, increasing the device's versatility.
[0033] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
