Description

Technical Field

[0001] This utility model relates to the field of billboard technology, specifically to a foldable acrylic billboard. Background Technology

[0002] In the field of commercial display and outdoor advertising, fan-shaped billboards, with their unique unfolding shape, can attract the audience's attention with a wider visual coverage angle, effectively improving the dissemination efficiency of advertising information. Therefore, they are widely used in scenarios such as shopping mall promotions, trade shows, and outdoor markets. Acrylic material, due to its high light transmittance, good color saturation, and strong weather resistance, has become the preferred material for making fan-shaped billboards, further enhancing the texture and attractiveness of the advertising display.

[0003] However, current fan-shaped billboards still have many technical challenges in practical applications: Firstly, the operation is not convenient enough. The unfolding and folding of traditional fan-shaped billboards mostly rely on manual operation, which is not only time-consuming and labor-intensive, but also poses a high safety risk in the use of large billboards. Secondly, the structural stability and wind resistance are inadequate. The supporting structure of existing fan-shaped billboards is often relatively simple. In outdoor environments, they are easily affected by natural factors such as wind. The unfolded fan surface is prone to swaying or even deformation, which not only affects the integrity of the advertising display but may also shorten the lifespan of the billboard.

[0004] Third, the process of changing advertising content is cumbersome. Traditional fan-shaped billboards typically use adhesive or clips to fix the advertising paper, requiring the entire fan-shaped structure to be disassembled for replacement. This is not only complicated but also carries the risk of damaging the acrylic sheet or advertising paper due to improper handling during disassembly, increasing maintenance costs. For commercial scenarios that require frequent updates to advertising information, this design severely restricts advertising efficiency. Fourth, the flexibility of movement and placement is insufficient. Most existing fan-shaped billboards are fixed structures. When the placement needs to be adjusted according to the needs of an event, it is often necessary to use external equipment for transportation, which is inconvenient to operate and difficult to quickly complete the placement and fixation, thus affecting the flexibility of advertising display. Therefore, developing a foldable acrylic fan-shaped billboard with automated unfolding and storage, stable structure, convenient advertising replacement, and flexible mobility has become an important direction for solving current technical pain points and promoting the upgrading of advertising display equipment. Utility Model Content

[0005] Based on the above description, this utility model provides a foldable acrylic billboard to solve the shortcomings of fan-shaped billboards, such as poor display effect, need for manual operation, fixed structure, need for external equipment for adjustment, and poor flexibility.

[0006] This utility model is achieved through the following technical solution: A foldable acrylic billboard includes a box body with rectangular openings on both sides. A positioning plate is hinged to each rectangular opening. The box body also has a storage assembly, which consists of two sets and is fixedly connected to the end faces of the two positioning plates. The positioning plates are also equipped with folding components with advertising paper wrapped around them. When the positioning plates drive the folding components to rotate downward around the hinge to a horizontal position, the advertising paper rotates downward and unfolds in a fan-shaped structure.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the storage component includes a rotating shaft disposed on the top of the box, and two rotating shafts are provided and arranged symmetrically, and pull ropes are wound around the surface of both rotating shafts. The box is also provided with a fixed pulley, and the pull ropes on the rotating shafts pass through the fixed pulleys and are fixedly connected to the end face of the positioning plate.

[0009] Furthermore, the end faces of the two rotating shafts are provided with transmission gears, the two transmission gears mesh with each other, and a servo motor is also provided inside the housing, the servo motor being connected to the end of one of the rotating shafts.

[0010] Furthermore, the folding assembly includes a mounting groove disposed on the end face of the positioning plate, a take-up roller is rotatably mounted in the mounting groove, one end of the advertising paper is bonded to the take-up roller, and the other end of the advertising paper is fixedly connected to the inside of the box. A take-up motor is also provided in the mounting groove, and the output end of the take-up motor is drivenly connected to one end of the take-up roller.

[0011] Furthermore, the take-up roller is configured as a tapered roller, and a tension sensor is also provided on the tapered roller.

[0012] Furthermore, the surface of the housing is also provided with limiting grooves, and two limiting grooves are provided and arranged symmetrically from top to bottom, with positioning holes provided through both ends of the two limiting grooves.

[0013] Furthermore, each of the four corners of the inner bottom surface of the box is provided with a mounting groove. An electric telescopic rod is fixedly installed above each mounting groove via a motor mount. The telescopic end of the electric telescopic rod is arranged vertically downward and is fixedly connected to a mounting base at the bottom. A roller is movably installed at the bottom of the mounting base.

[0014] Furthermore, the rollers are configured as omnidirectional wheels.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. This application improves upon existing fan-shaped billboards by combining a box body with a fan-shaped display structure. It can be driven by a servo motor and can synchronously control the positioning plates on both sides to precisely deflect around the hinge, thereby achieving automated unfolding (horizontal state) and storage (folding into the box body) of the advertising structure. Moreover, it eliminates the need for manual operation, greatly improving ease of use, and is especially suitable for the rapid deployment and recycling of large billboards. 2. During the deflection of the positioning plate, the winding roller of the folding assembly simultaneously releases the advertising paper under the action of the winding motor, causing the advertising paper to unfold in a fan-shaped structure, thus expanding the visual coverage angle. This design retains the advantage of fan-shaped billboards in attracting attention, while ensuring the stability of the unfolded shape through mechanical linkage, thereby enhancing the effect of conveying advertising information. 3. When not in use, the positioning plate and advertising paper can be completely folded into the box using the storage components, which greatly reduces the size of the equipment and the storage space occupied. The bottom wheels facilitate transportation and transfer, effectively solving the problem of inconvenient storage and handling of traditional large billboards. Attached Figure Description

[0017] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0019] Combination Figure 1-5 As shown, a foldable acrylic billboard includes: The box body 1 serves as the main structure of the entire billboard and is made of acrylic sheet. A limiting groove 12 is provided on its surface for quick installation of the advertising board and to display the core area of ​​the advertisement. Rectangular openings 11 are also provided on both sides of the box body 1. Positioning plate 2 is set as a rectangular acrylic plate structure and is located at the rectangular opening 11, so that its bottom end is movably hinged to the bottom of the rectangular opening 11. The storage component 3 is set inside the box 1 and located at the top of the rectangular opening 11. It can tilt outward in conjunction with the positioning plate 2, so that the advertising paper can be unfolded outward in a fan-shaped structure, thereby expanding the display area. The folding component 4 is set on the positioning plate 2 to assist the storage component 3 in rolling up the fan-shaped advertising paper during recycling, thereby preventing the advertising paper from wrinkling and facilitating subsequent recycling.

[0020] Specifically, in this embodiment, it is mainly used for commercial displays and promotional activities. Its fan-shaped structure can better display advertising content. At the same time, during the display process, the limiting groove 12 on the surface of the box 1 can be used to install L-shaped advertising boards to match the corresponding items for display, thereby further improving its display effect. It is particularly eye-catching when used inside large shopping malls.

[0021] Therefore, in this embodiment, the positioning plate 2 should be connected to the rectangular opening 11 by a hinge structure, so that it can rotate around the hinge to a vertical or horizontal state. In the horizontal state, it is attached to the ground for easy display. In the vertical state, it is in the storage state, that is, the state when the advertising paper is stored inside the box 1.

[0022] The storage component 3 includes two rotating shafts 31 located on the top of the housing 1. Each rotating shaft 31 has a cable winding groove formed by a circular baffle. A pull rope 34 is wound in the cable winding groove. At the same time, a fixed pulley 33 is located below the rotating shaft 31 and near the top of the rectangular opening 11. The pull rope 34 passes through the fixed pulley 33 and is fixedly connected to the end face of the positioning plate 2 (using a spring self-locking hook to connect with the hanging ring, which can be separated when displaying and re-fastened when storing, thus preventing the pull rope 34 from obstructing the advertising paper). Therefore, when the rotating shaft 31 rotates, the positioning plate 2 can be pulled upward or downward by the pull rope 34.

[0023] In addition, the two rotating shafts 31 need to rotate relative to each other, so transmission gears are provided at the ends of the two rotating shafts 31, and the two transmission gears mesh with each other. One of the rotating shafts 31 is also equipped with a servo motor 32, which is fixedly connected to the housing 1 through a motor mount.

[0024] The folding assembly 4 includes a mounting groove on the end face of the positioning plate 2. A winding roller 41 is rotatably mounted in the mounting groove via a bearing structure. The winding roller 41 is a tapered roller, meaning that the diameter of the downward-facing end is smaller than the diameter of the other end. Therefore, the advertising paper, which is configured as a fan-shaped structure, can be wound up by the winding roller 41 and tightly adhered to the roller surface, avoiding wrinkles during the folding process and facilitating subsequent recycling.

[0025] One end of the advertising paper is bonded to the take-up roller 41, and the other end is fixedly connected to the inside of the housing 1 (it can be bonded, fastened with clamping plates, or fixed at the edge by means of pins, etc.). The mounting slot is also equipped with a take-up motor 42, and the output end of the take-up motor 42 is connected to one end of the take-up roller 41 to control the take-up speed of the take-up roller 41.

[0026] During the folding process, the travel speed of the winding component and the folding component 4 needs to be adjusted simultaneously to ensure that the unwinding speed matches the downward unfolding speed of the positioning plate 2, preventing excessive speed from pulling the advertising paper, thereby straightening the advertising paper without damaging it and improving the display effect.

[0027] Therefore, a controller and a battery should be installed inside the housing 1. The controller is preferably a Renesas RX24T and is electrically connected to both the winding motor 42 and the servo motor 32 via wires to control the two motors to work together. In addition, a tension sensor, preferably a TS80 cantilever tension sensor, should be installed on the winding roller 41 to sense the tension of the advertising paper and electrically connect it to the controller to prevent excessive tension from causing damage.

[0028] In addition, to facilitate the transportation and use of the entire equipment, rollers 7 should be provided at the bottom of its housing 1. In actual use, if only rollers 7 are used for support, not only will the rollers 7 be easily damaged, but they will also be prone to slippage. Therefore, mounting slots should also be provided on the inner bottom surface of the housing 1. Four mounting slots are arranged at the four corners. An electric telescopic rod 5 is mounted on the top of each mounting slot via a motor mount. The bottom of the electric telescopic rod 5 is fixedly connected to a mounting base 6. Rollers 7 are movably mounted on the mounting base 6. All four electric telescopic rods 5 are electrically connected to the controller via wires. Through the synchronous control of the controller, the four electric telescopic rods 5 can retract the mounting base 6 and the rollers 7 set on the mounting base 6 into the housing 1, or push them outward, thereby effectively avoiding the instability caused by the support of rollers 7, and avoiding excessive friction between the rollers 7 and the ground. To further improve its convenience, the rollers 7 should also be set as universal wheels.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
