Description

Technical Field

[0001] The present invention relates to the technical field of multimedia exhibition display equipment, and in particular to a mobile multimedia exhibition display stand. Background Art

[0002] Exhibition display stands are the core facilities used for product display, information dissemination or decoration in public places such as exhibitions, trade fairs, shopping malls, etc. With the rapid development of the exhibition economy, as an important carrier for information transmission and product promotion, exhibition display stands are facing increasing market demands in terms of functionality and convenience. However, traditional display stands still have obvious limitations in modern exhibition application scenarios: Firstly, in terms of function integration, traditional display stands mostly adopt static display boards or simple shelf structures, which are difficult to meet the multimedia display needs in the digital age. Although some display devices are already equipped with display screens, due to the need for independent installation of the display platform and multimedia devices, the overall integration degree is insufficient. This modular defect not only reduces the space utilization rate but may also cause structural stability problems, specifically manifested as: limited viewing angle adjustment, difficulty in flexibly adapting to the spatial layout of different exhibition areas, and difficulty in dynamically adjusting according to the height of the audience's line of sight; Secondly, in terms of mobile deployment, the independent design of traditional display stands results in complex disassembly and assembly processes. The handling process often requires the assistance of special tools, which not only increases the risk of damage during transportation and the inconvenience caused by repeated disassembly and assembly but also significantly increases the labor cost and time cost.

[0003] Based on the above problems, it is particularly important to develop a mobile multimedia exhibition display stand that integrates dynamic multimedia display functions and rapid deployment capabilities. Summary of the Invention

[0025] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Embodiment 1: A movable multimedia exhibition display rack, as Figures 1-9 shown, includes: The movable bottom platform 1 is a triangular-structured movable bottom platform. Its top has a triangular platform space for placing exhibits, and the inside of the movable bottom platform 1 is hollow and can be used as a space for storing and reserving exhibits, effectively utilizing the internal space of the movable bottom platform 1 to enhance the storage function. In addition, the bottom of the movable bottom platform 1 is also equipped with universal wheels with a self-locking function, which not only improves the mobility of the overall device but also ensures the stability when in a fixed position, and is especially suitable for exhibition scenarios that require frequent venue changes; The moving cylinder 3 is penetrated and slidably arranged on the moving base 1, allowing the moving cylinder 3 to slide up and down in the vertical direction. The inside of the moving cylinder 3 is of a hollow structure. Three rows of jacks 30 are arranged at intervals along the circumferential direction on the surface of the moving cylinder 3, which is convenient for inserting hooks or pins to hang exhibits, so as to make full use of the space of the moving cylinder 3, ensure the integrity of the exhibit display, and at the same time improve the functionality of the overall display rack and the diversity of the exhibit layout. A convex block 31 is fixedly arranged on one side of the bottom end of the moving cylinder 3, and an electric telescopic rod 32 with its telescopic end facing upward is installed inside the moving base 1. The telescopic end of the electric telescopic rod 32 is connected to the moving cylinder 3. Through the drive of the electric telescopic rod 32, the lifting movement of the moving cylinder 3 can be realized, so as to flexibly adjust the height of the exhibits and ensure the display effect. The extension base 4 is fixedly arranged at the top end of the moving cylinder 3. A main digital display screen 41 is installed on the front side of the extension base 4. A hinge seat 411 is fixedly arranged on each of the left and right sides of the outer shell of the main digital display screen 41. A connecting seat 421 is hingedly arranged on each hinge seat 411, and a secondary digital display screen 42 is installed on each connecting seat 421. To further ensure the display effect, by integrating the main digital display screen 41 and the secondary digital display screen 42 into one, an integrated multimedia display function is provided for the display rack. And compared with the structure where traditional media display and exhibit display are separated, this design not only makes the overall structure more compact, but also in the exhibition environment, it can more efficiently combine physical exhibits with multimedia animations and pictures, and quickly and vividly display the unique features of the exhibits. Moreover, by using the hinge design between the hinge seat 411 and the connecting seat 421, the secondary digital display screens 42 on both sides are allowed to be adjusted at an angle according to actual needs, so as to realize the display methods of surrounding or unfolding. Such a flexible setting effectively overcomes the limitations of the previous fixed-angle display, making the display effect more diverse. In addition, combined with the triangular structure of the moving base 1, the two secondary digital display screens 42 can rotate on the side of the main digital display screen 41 and the three are spliced into a stable triangular structure, ensuring that a comprehensive and coherent visual experience can be provided when viewed from different angles, and at the same time facilitating the staff to quickly deploy and adjust the display content to meet different display needs.

[0027] Three expansion boards 5 are hingedly arranged on each side of the moving base 1. Guide sleeves 6 with the same quantity and layout as the expansion boards 5 are arranged at the inner top of the moving base 1. A top plate 61 that is in contact and cooperation with the adjacent expansion board 5 is slidably arranged in the guide sleeve 6. A convex rod 611 is arranged at the end of the top plate 61. A pushing member that is in contact and cooperation with the convex rod 611 is rotated inside the moving base 1 for pushing the top plate 61 to move, and the convex block 31 is also in contact and pushing cooperation with the pushing member.

[0028] Such as Figure 8 and Figure 9As shown in the figure, the top moving part includes an engagement ring 62 rotatably arranged in the middle area at the top inside the moving base 1. The engagement ring 62 is concentric with the moving cylinder 3, and arc-shaped triangular plates 63 are circumferentially and spacedly arranged on the engagement ring 62 with the same quantity and layout as the convex rods 611. The arc-shaped triangular plates 63 are in contact and cooperation with the adjacent convex rods 611, and a guide plate 64 in contact and cooperation with the convex block 31 is arranged at the bottom of the engagement ring 62.

[0029] Specifically, when the electric telescopic rod 32 is driven, it drives the moving cylinder 3 to move up and down. During the upward movement of the moving cylinder 3, at the same time, the convex block 31 arranged on it comes into contact with the guide plate 64. For details, see Figure 8 As shown in the figure, the guide plate 64 is designed in the form of a triangular plate with an inclined surface facing downward. When the convex block 31 slides along this inclined surface and applies pressure, it will push the engagement ring 62 to rotate. The rotation of the engagement ring 62 makes the uniformly distributed arc-shaped triangular plates 63 on it gradually approach the corresponding convex rods 611. As the arc-shaped triangular plates 63 approach and contact the convex rods 611, they push the corresponding top plates 61 to slide in the guide sleeves 6. In this way, the top plates 61 on three sides expand outwards, gradually approach their respective corresponding expansion plates 5, and finally lift the corresponding expansion plates 5. In this way, each expansion plate 5 is cooperatively unfolded to form an expanded display plane, thus significantly increasing the exhibit placement area on the moving base 1. In this way, by adopting the above mechanical linkage method, compared with the traditional separate installation situation, it has obvious advantages in terms of deployment speed and overall functionality. It not only simplifies the deployment process of each area of the display rack, effectively improves the overall adaptability and versatility, but also provides an efficient and flexible display platform for the exhibition environment.

[0030] As Figure 9 shown in the figure, the ends of the arc-shaped triangular plates 63 all have abutting ends 631 extending outwards. The side of the abutting end 631 facing the corresponding convex rod 611 is an arc surface for fitting with the convex rod 611 to form abutting adaptation.

[0031] As Figure 3 、 Figure 4 and Figure 6 shown in the figure, it also includes guide rails 43. Guide rails 43 are fixedly arranged at the rear sides of the secondary digital displays 42. A linear groove 431 is formed on the guide rails 43. A connecting rod 44 is hinged on each of the left and right sides of the extension seat 4. The ends of the connecting rods 44 are slidably embedded in the linear grooves 431 on the same side.

[0032] When in use, the overall deployment of the display rack is started first, and the mobile base 1 is pushed to reach a suitable display area. Then the electric telescopic rod 32 can be started to drive the connected mobile cylinder 3 to move upward, causing the protrusion 31 to contact the guide plate 64, and then the connecting ring 62 is driven to rotate through the inclined surface extrusion, causing the arc-shaped triangular plate 63 on it to approach and contact the corresponding protrusion 611, thereby pushing the connected top plate 61 to slide on the guide sleeve 6, and each top plate 61 is pushed out and contacts the corresponding expansion plate 5, thereby quickly lifting the expansion plate 5, so that the expansion plates 5 at three locations are synchronously unfolded, thereby extending the placement platform area of ​​the mobile base 1, and synchronously opening the built-in storage space of the mobile base 1, and then the two auxiliary digital display screens 42 can be pulled to make the connected connection seats 421 rotate on the corresponding hinge seats 411, so that the auxiliary digital display screens 42 on both sides can be adjusted to the required angle around the main digital display screen 41, or arranged as follows Figure 2 and Figure 5 The two forms shown, then the hook or the pin can be inserted into the socket 30 at the desired position, and then the exhibits can be placed on the mobile base 1, the expansion board 5 and the hook (or the pin), so as to complete the deployment of the exhibits, and then the auxiliary digital display screen 42 and the main digital display screen 41 can be turned on, and a comprehensive display can be performed by playing animations and pictures combined with physical exhibits to enhance the exhibition effect.

[0033] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 5 As shown, it also includes a frame cover 2, which is provided with three support plates 21 circumferentially arranged on the lower side of the frame cover 2, and the top circumferentially of the movable base 1 is provided with insertion rods 11 with the same number and layout as the support plates 21, and the insertion rods 11 are plugged into and matched with the corresponding support plates 21; when use is completed, the components of the display rack can be reset, and the frame cover 2 can be covered on the movable base 1, so that the support plates 21 are inserted into the insertion rods 11 at the corresponding positions, so as to firmly fix the position of the frame cover 2; when the display rack needs to be used again, the frame cover 2 can be directly removed, because the support plates 21 and the insertion rods 11 adopt a convenient detachable connection method, which makes the disassembly and assembly process of the frame cover 2 simpler and faster. This design not only ensures that the frame cover 2 can effectively shield and protect the precision parts inside the display rack to prevent them from being affected by external factors, but also ensures the safety and durability of the internal components, providing reliable guarantee for the long-term and stable use of the display rack.

[0034] like Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, it further includes a storage frame 12. The storage frame 12 is slidably embedded on each side of the movable bottom platform 1. When the expansion board 5 is in the closed state, the storage frame 12 is restricted from being opened by it, thus ensuring the structural integrity of the display stand when it is not in use. When the expansion board 5 is fully unfolded, the restriction on the storage frame 12 will be released synchronously, enabling it to move freely, so that it can be pulled out from the inside of the movable bottom platform 1, facilitating the use or storage of exhibits.

[0035] As Figure 5 and Figure 7 As shown, it further includes a baffle 121. A baffle 121 is provided on each side surface of the movable bottom platform 1. The bottom of the baffle 121 is connected to the storage frame 12 on the same side. The baffle 121 can effectively limit the sliding range of the storage frame 12 and serve as a reset reference for the storage frame 12 in the unused state.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
