Description

Technical Field

[0001] The present application relates to the field of exhibition display technology, and in particular to a dynamic exhibition device. Background Art

[0002] Large multimedia display screens are used in some large-scale exhibitions and other activities, and are combined with corresponding sound and light to better display images and attract people.

[0003] Large multimedia display screens at existing exhibitions are generally composed of multiple LCD screens assembled on corresponding steel structures.

[0004] With regard to the above-mentioned related technologies, the angle of the LCD screen cannot be changed after installation, so that the entire multimedia display screen tends to be static, and the multimedia display content can only be confined to a plane, resulting in limited display effects. Summary of the invention

[0005] In order to improve the display effect, the present application provides a dynamic exhibition device.

[0006] The present application provides a dynamic exhibition device that adopts the following technical solution.

[0007] A dynamic exhibition device comprises a plurality of front display screens for displaying images and a mounting frame for mounting the front display screens, wherein the mounting frame is provided with a horizontal rotation device corresponding to each front display screen, and each horizontal rotation device comprises a fixed central axis detachably connected to the mounting frame, the fixed central axis is rotatably connected to a rotating inner frame for connecting the front display screen, the rotating inner frame is provided with a translation motor for driving the rotating inner frame to rotate around the axis of the fixed central axis, and the fixed central axes corresponding to two adjacent front display screens can be coaxially detachably connected.

[0008] By adopting the above technical solution, the rotating inner frame rotates relative to the fixed central axis, so that the front display screen can change the display angle accordingly, so as to realize the dynamic change of the displayed content of the front display screen as needed, so that the front display screen with different rotation angles can form different text graphics in space, so as to improve the display effect.

[0009] Optionally, the output shaft of the translational motor is coaxially fixedly connected with a motor gear, the fixed middle shaft is coaxially fixedly connected with a shaft gear, and a translational synchronous belt is transmission-connected between the shaft gear and the motor gear.

[0010] By adopting the above technical solution, the pan-rotating motor does not need to be coaxially arranged with the fixed central axis, thereby reducing the possibility of the pan-rotating motor being subjected to greater axial pressure. At the same time, the setting of the pan-rotating synchronous belt can also enable the setting point of the pan-rotating motor to be farther away from the fixed central axis. According to the lever principle, when the output power of the pan-rotating motor is relatively small, it can also better drive the entire rotating inner frame, the front display screen, the pan-rotating motor itself, and other objects that may be installed later to rotate. At the same time, compared with gear meshing, the setting of the pan-rotating synchronous belt does not require gears with larger diameters, thereby saving installation space.

[0011] Optionally, the mounting frame includes a base frame, a vertical rotation frame rotatably connected to the base frame and connected to a fixed central axis corresponding to a row of front display screens, and a vertical rotation motor disposed on the base frame and driving the vertical rotation frame to rotate, wherein the rotation axis of the vertical rotation frame is horizontal and perpendicular to the axis of the fixed central axis.

[0012] By adopting the above technical solution, the vertical rotation frame is rotated in a rotation plane different from the rotating inner frame, so that the front display screen can perform different dynamic displays at more angles, and the rotation axis of the vertical rotation frame is horizontal, so that corresponding small angle adjustments can be made according to the position of the main viewers, so that when there is a large height difference between the front display screen and the viewer, the front display screen can make corresponding adjustments while the entire mounting frame remains vertically and stably installed.

[0013] Optionally, the vertical motor output shaft is coaxially fixedly connected with a vertical motor gear, each vertical frame is coaxially fixedly connected with a frame gear, and a vertical synchronous belt is transmission-connected between the frame gear and the vertical motor gear.

[0014] By adopting the above technical solution, all the vertical rotation frames can rotate synchronously, and the corresponding frame gears can be set in the mounting frame, so that the distance between two adjacent front display screens in the same row of a vertical rotation frame is not too large, which helps to improve the display effect.

[0015] Optionally, a side of the rotating inner frame away from the front display screen is detachably connected to a rear display screen capable of displaying images, and the side of the rear display screen displaying the image is perpendicular to the side of the front display screen displaying the image.

[0016] By adopting the above technical solution, after the front display screen is rotated by a certain angle, there is a gap between two adjacent front display screens, so that no image is displayed between the two adjacent front display screens when viewed from a corresponding angle. The setting of the rear display screen can better solve this problem, so as to further improve the display effect after the front display screen is rotated.

[0017] Optionally, the rotatable inner frame is detachably connected to an outer mounting frame connected to the periphery of the front display screen. The horizontal rotation device is located in the corresponding outer mounting frame. A group of peripheral display screens capable of displaying images are detachably connected to the four peripheries of each outer mounting frame. Each group of peripheral display screens surrounds the corresponding horizontal rotation device. The side of the peripheral display screen for displaying the image is perpendicular to the side of the front display screen for displaying the image.

[0018] By adopting the above technical solution, the setting of the outer mounting frame enables better fixation of the front display screen when the size of the front display screen is large, improving the stability of the front display screen after installation. Moreover, the setting of the peripheral display screens can block the horizontal rotation device and the outer mounting frame, so that when the front display screen rotates at a certain angle and the peripheral side of the outer mounting frame is exposed, the peripheral display screens can display corresponding patterns to enhance the display effect after the front display screen rotates at a certain angle.

[0019] Optionally, frame-side display screens are detachably connected to the peripheral sides of the vertical rotation frame. The side of the frame-side display screen for displaying the image is perpendicular to the side of the front display screen for displaying the image.

[0020] By adopting the above technical solution, when the vertical rotation frame rotates at a small angle, due to the existence of the frame-side display screens, the exposed peripheral sides of the vertical rotation frame can also display corresponding images, enhancing the overall display effect when the vertical rotation frame rotates.

[0021] Optionally, a group of fitting blocks are fixedly connected between the adjacent sides of the two outer mounting frames. The fitting blocks are used to connect the peripheral display screens. The two groups of fitting blocks of the two outer mounting frames are detachably connected in a one-to-one correspondence.

[0022] By adopting the above technical solution, it is possible to drive multiple outer mounting frames to perform corresponding rotations according to needs by a rotatable inner frame, and then drive multiple front display screens to rotate by a rotatable inner frame, so as to further increase different types of dynamic display effects.

[0023] Optionally, a group of reinforcing rod screw holes are formed through the fitting blocks. The same reinforcing rod is sleeved in a row of aligned reinforcing rod screw holes. End screws are threadedly connected to the two farthest reinforcing rod screw holes in the same row. The end screws are rotatably connected to an intermediate block. One end of the intermediate block away from the end screw is rotatably connected to an end screw cylinder threadedly connected to the outer wall of the end of the reinforcing rod. The distance between the axis of the end screw cylinder and the axis of the end screw is the distance between the two reinforcing rod screw holes in the same group.

[0024] By adopting the above technical solution, the setting of the reinforcing rod improves the connection strength between a row of installation outer frames to a certain extent. And the setting of the end screw rod makes it difficult for the end of the reinforcing rod to be exposed outside the two farthest-fitting blocks in a row, so that the corresponding peripheral display screen is not easily restricted by the reinforcing rod during installation. At the same time, when the end screw cylinder is correspondingly connected to the reinforcing rod, since the axes of the end screw cylinder and the end screw rod are not consistent, it is not easy to drive the end screw rod to rotate synchronously when the end screw cylinder is rotated.

[0025] Optionally, a through cylinder for the reinforcing rod to tightly pass through is threadedly connected to the reinforcing rod screw hole. A depth-determining block is fixedly connected to the circumferential outer wall of the through cylinder, and two adjacent depth-determining blocks are respectively abutted against the opposite sides of the two fitting blocks that are in contact with each other.

[0026] By adopting the above technical solution, it is not easy for the reinforcing rod to directly contact the thread of the reinforcing rod screw hole, reducing the possibility of damage to the reinforcing rod screw hole, so that the peripheral display screen can be better connected to the corresponding fitting block by screwing in bolts.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. The front display screens at different rotation angles can form different characters, graphics, etc. in space to improve the display effect;

[0029] 2. The vertical rotation frame rotates in a rotation plane different from that of the rotation inner frame, enabling the front display screen to perform different dynamic displays at more angles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] The present application embodiment discloses a dynamic exhibition device, referring to Figure 1 and Figure 2 , including a vertical mounting frame 2 that can be anchored on the ground or connected to other mounting bases by bolts, wherein several rows of horizontal front display screens 1 are mounted in the mounting frame 2, the front display screens 1 are vertical, and several front display screens 1 are evenly distributed in each row in the horizontal direction, and a horizontal rotating device 3 is installed on the mounting frame 2 corresponding to each front display screen 1, so that the front display screen 1 can rotate in the horizontal plane, so that the front display screen 1 can realize dynamic display in space by adjusting the angle in addition to displaying images on its own vertical side, thereby improving the display effect.

[0038] Reference Figure 2 and Figure 3 The horizontal rotation device 3 includes a fixed central axis 4 which is detachably connected to the mounting frame 2 by bolts, the fixed central axis 4 is vertical, and two coaxial and adjacent fixed central axes 4 can be detachably connected, a rotating inner frame 41 is coaxially rotatably connected at the middle position of the fixed central axis 4, the rotating inner frame 41 is attached to the back of the front display screen 1, the rotating inner frame 41 is detachably connected to a pan-rotating motor 42 by bolts, the output shaft of the pan-rotating motor 42 is vertical, the output shaft of the pan-rotating motor 42 is coaxially fixedly connected to a motor gear 43, the fixed central axis 4 is coaxially fixedly connected to a shaft gear 44, the diameter of the shaft gear 44 is smaller than the horizontal width of the rotating inner frame 41, a pan-rotating synchronous belt 45 is transmission-connected between the shaft gear 44 and the motor gear 43, and the pan-rotating synchronous belt 45 is horizontal, so that the pan-rotating motor 42 can be set at a position where the rotating inner frame 41 is away from the fixed central axis 4, and the diameter of the shaft gear 44 or the motor gear 43 is not easy to be too large.

[0039] Reference Figure 3, on the side of the rotating inner frame 41 away from the slewing motor 42, a counterweight 28 is detachably connected by bolts, making the rotating inner frame 41 tend to be balanced. A controller 11 is detachably connected by bolts at the side of the rotating inner frame 41 where the counterweight 28 is provided. The controller 11 is electrically connected to the slewing motor 42 to control the operation of the slewing motor 42. At the upper end of the fixed central shaft 4, a conductive slip ring 29 is coaxially and fixedly connected. The conductive slip ring 29 is used to electrically connect the controller 11 and the slewing motor 42 to an external power supply, and enables the controller 11 to be electrically connected to an external computer, so as to finally realize the control of the rotation angle, rotation duration, etc. of the rotating inner frame 41 according to the preset program or corresponding instructions of the external computer. In addition, the rotating inner frame 41 is detachably connected by bolts with a positioning member 12. The positioning member 12 can be a positioning sensor or an absolute encoder. The positioning member 12 is electrically connected to an external analog-to-digital converter through the conductive slip ring 29. After signal conversion, the corresponding digital signal is input into the external computer for processing to obtain the rotation angle of the rotating inner frame 41 and the angle in the current state.

[0040] Refer to Figure 2 and Figure 4 , an installation outer frame 34 is installed on the rotating inner frame 41 concentrically with the center point. The horizontal width of the installation outer frame 34 is the same as the horizontal width of the rotating inner frame 41. A plurality of frame rods 26 are evenly and detachably connected by bolts between the installation outer frame 34 and the rotating inner frame 41. The frame rods 26 prevent the installation outer frame 34 from being displaced relative to the rotating inner frame 41. A metal frame is provided around the front display screen 1, so that the front display screen 1 can be detachably connected to the vertical side of the installation outer frame 34 by bolts. A set of fitting blocks 37 are fixedly connected to each of the six sides of the installation outer frame 34. Each fitting block 37 is provided with a set of two reinforcing rod screw holes 38 for the bolt connection setting of the front display screen 1.

[0041] Refer to Figure 4, the two sets of fitting blocks 37 on the adjacent side surfaces of two adjacent mounting outer frames 34 can be fitted together, so that the corresponding two sets of reinforcing rod screw holes 38 can be aligned and communicated with each other, so that a rotating inner frame 41 can be arranged corresponding to a row of several mounting outer frames 34 in a horizontal state. When the corresponding rotating inner frame 41 rotates, it can drive a whole row of mounting outer frames 34 and a whole row of front display screens 1 to rotate, so as to obtain more types of dynamic displays. A reinforcing rod 39 is passed through a row of reinforcing rod screw holes 38 corresponding to a row of mounting outer frames 34. Two or four reinforcing rods 39 can be evenly arranged for each row of horizontal mounting outer frames 34. In addition, the reinforcing rod 39 can also be arranged corresponding to a column of mounting outer frames 34 in the same vertical direction. In this embodiment, two reinforcing rods 39 are selected for each row of horizontal mounting outer frames 34. A through-tube 24 is coaxially threadedly connected to each reinforcing rod screw hole 38 through which the reinforcing rod 39 passes. The outer circumferential wall of the reinforcing rod 39 is coaxially slidably connected to the inner circumferential wall of the through-tube 24. A depth-setting block 25 is coaxially fixedly connected to the outer circumferential wall of the through-tube 24. When the depth-setting block 25 abuts against the fitting block 37, the end face of the end of the through-tube 24 passing through the fitting block 37 is flush with the side surface of the corresponding fitting block 37 facing away from the depth-setting block 25, so that a through-tube 24 only contacts the reinforcing rod screw hole 38 of one of the two fitting blocks 37 that are fitted together. When there are certain differences between the reinforcing rod screw holes 38 of the two fitting blocks 37 that are fitted together, the through-tube 24 is not likely to damage the reinforcing rod screw hole 38 with a large difference.

[0042] Referring to Figure 4 , end screws 21 are coaxially threadedly connected to the reinforcing rod screw holes 38 of the two fitting blocks 37 that are farthest apart in a row of mounting outer frames 34. A screw limiting piece 27 that can abut against the fitting block 37 is coaxially fixedly connected to the end screw 21, so that the end of the end screw 21 inserted into the reinforcing rod screw hole 38 is not likely to be exposed outside the fitting block 37. Intermediate blocks 23 are rotatably connected to the adjacent ends of two end screws 21 with the same axis. The intermediate blocks 23 can rotate around the axis of the end screws 21. An end screw cylinder 22 is rotatably connected to the end of the intermediate block 23 away from the connected end screw 21. The rotation axis of the end screw cylinder 22 is the same as the rotation axis of the end screw 21. The inner circumferential wall of the end screw cylinder 22 is coaxially threadedly connected to the outer circumferential wall of the reinforcing rod 39. The axes of the end screw cylinder 22 and the end screw 21 correspond to the axes of the two reinforcing rod screw holes 38 of a corresponding fitting block 37 one by one, so that when the end screw cylinder 22 rotates, the end screw 21 is not likely to be driven to rotate.

[0043] Referring to Figure 2 and Figure 3, the peripheral display screens 35 are detachably connected to the four peripheral sides of the mounting frame 34 adjacent to the front display screen 1 by bolts, and the width of the peripheral display screens 35 is consistent with the horizontal width of the mounting frame 34, so that the peripheral display screens 35 surround the mounting frame 34, so that after the mounting frame 34 is rotated at a certain angle, the peripheral display screens 35 are exposed to display the corresponding images, so that the mounting frame 34 and the internal horizontal rotation device are not easily exposed. In addition, the horizontal width of the mounting frame 34 can be controlled to be smaller, so that the width of the peripheral display screens 35 can be smaller, so that the distance between two adjacent mounting frames 34 can be controlled within a smaller range (the horizontal width of the mounting frame 34 is increased in this application for the convenience of display). A group of two rear display screens 33 are detachably connected to the side of each mounting frame 34 away from the front display screen 1 by screws. The rear display screens 33 are vertical, and the sides of the two rear display screens 33 in the same group display images facing each other. The two rear display screens 33 in the same group are close to the center point of the corresponding mounting frame 34, so that when two adjacent mounting frames 34 in the same row are rotated at a large angle, a gap is formed between the two adjacent mounting frames 34 in the same row, and the rear display screens 33 can display images through the corresponding gap.

[0044] Reference Figure 5 In another implementation of the present embodiment, the mounting frame 2 includes a base frame 46, which is vertical and can be fixed on the ground. The base frame 46 is a rectangular frame. The two vertical inner walls of the base frame 46 are rotatably connected to a plurality of horizontal vertical rotation frames 47. The rotation axis of the vertical rotation frame 47 is horizontal, and the rotation axis of the vertical rotation frame 47 passes through its own center point. Each vertical rotation frame 47 is provided for installation of a row of front display screens 1 and a corresponding horizontal rotation device 3. The four sides of the vertical rotation frame 47 adjacent to the corresponding row of front display screens 1 are detachably connected to the frame side display screens 36 by bolts, so that when the vertical rotation frame 47 rotates, the frame side display screens 36 are exposed to display images. A plurality of frame gears 31 are rotatably connected in a vertical section of the base frame 46, and each frame gear 31 is fixedly connected to a corresponding vertical frame 47 with the rotation axis. A vertical motor gear 49 is rotatably connected in the vertical section of the base frame 46 where the frame gear 31 is arranged. A vertical motor 48 is fixedly connected in the base frame 46, and the output shaft is coaxially fixedly connected to the vertical motor gear 49. A vertical synchronous belt 32 is transmission-connected between the vertical motor gear 49 and the frame gear 31, so that all the vertical frames 47 rotate synchronously.

[0045] The implementation principle of a dynamic exhibition device according to an embodiment of the present application is as follows: The horizontal rotation motor 42 drives the motor gear 43 to rotate. Since the shaft gear 44 is stationary, the motor gear 43 is forced to rotate around the fixed central axis 4, causing the rotating inner frame 41 to rotate and the front display screen 1 to rotate around the axis of the corresponding fixed central axis 4. Additionally, a vertical rotation frame 47 can be set according to needs, enabling the front display screen 1 to rotate at multiple angles to better improve the display effect.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
