Description

Technical Field

[0001] This utility model relates to the field of projection technology, and in particular to a multi-person interactive linkage device based on a large space. Background Technology

[0002] Multi-person interactive projection devices are innovative equipment that uses holographic projection technology to present virtual scenes in a realistic three-dimensional form in real space, thereby enabling real-time interactive experiences for multiple people. They are suitable for product exhibitions, car and fashion shows, stage performances, interactive activities, bar entertainment, and other venue interactive projections.

[0003] Traditional projectors are typically fixed to the wall or ceiling. This installation method makes it difficult to flexibly adjust the projection position according to different activity scenarios and personnel distribution, affecting the interactive effect. Furthermore, the lack of effective storage and protection measures means that when not in use, the projector is exposed to dust and moisture, shortening its lifespan. Therefore, we propose a large-space, multi-person interactive linkage device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where projectors directly fixed to the wall or ceiling are difficult to adjust their projection position flexibly according to different activity scenarios and personnel distribution, thus affecting the interactive effect. At the same time, they lack effective storage and protection measures. Therefore, this invention proposes a multi-person interactive linkage device based on large spaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large-space multi-person interactive linkage device includes a sliding rail installed on the ceiling, a slider slidably connected to the bottom of the sliding rail, a mounting box connected to the bottom of the slider, and a projector fixedly connected to the top inner wall of the mounting box. The device also includes:

[0007] An adjustment component, mounted on the slide rail, is used to adjust the position of the slider;

[0008] Storage components are installed on the mounting box to protect and store the projector.

[0009] In one possible design, the adjusting assembly includes a first lead screw rotatably disposed inside the slider. A motor box is fixedly connected to one side of the slide rail, and a first motor is fixedly disposed inside the motor box. The output end of the first motor is fixedly connected to the first lead screw, and the first lead screw is threaded through the slider.

[0010] In one possible design, the adjustment assembly further includes a bidirectional threaded rod rotatably disposed inside the slider. Two rotating rings are threadedly connected to the bidirectional threaded rod, and the two rotating rings are respectively located on the positive and negative thread sections of the bidirectional threaded rod. The bottom of each of the two rotating rings is rotatably connected to a connecting rod, and the bottom ends of the two connecting rods are rotatably connected to the top of the mounting box. A second motor is fixedly disposed on one side of the slider, and the output end of the second motor is fixedly connected to the bidirectional threaded rod.

[0011] In one possible design, a limit block is fixedly provided at the bottom of the slider, and the top outer walls of the two rotating rings are each provided with a groove corresponding to the limit block, and both grooves are slidably connected to the limit block.

[0012] In one possible design, the storage component includes a protective box that is slidably fitted onto the outer wall of the mounting box. The protective box has openings on both sides, and sealing plates are slidably installed within each opening. U-shaped frames are fixedly connected to both sides of the mounting box, and connecting blocks are fixedly connected to both sides of the protective box. Two connecting blocks extend into the interior of their respective U-shaped frames. A sliding rod is fixedly installed inside one U-shaped frame, passing through and slidably connecting to the corresponding connecting block. A second lead screw is rotatably installed inside the other U-shaped frame, and a third motor is fixedly connected to the bottom of the other U-shaped frame. The output end of the third motor is fixedly connected to the second lead screw, which is threaded through the corresponding connecting block. Transmission components for automatically opening and closing the two sealing plates are provided on both sides of the mounting box.

[0013] In one possible design, the transmission assembly includes two transmission rods, which are rotatably mounted on one side of the mounting box via a common rotating rod. The bottom ends of the two transmission rods are rotatably connected to two corresponding sealing plates. Limiting wheels are fixedly mounted on one side of each transmission rod. A limiting groove is formed on the inner wall of one side of the protective box, and both limiting wheels extend into the limiting groove. In this application, the device is first mounted on the top of the wall via a slide rail. When horizontal adjustment is required, the first motor located in the motor box starts, and its output drives the first lead screw to rotate. The first motor converts electrical energy into mechanical energy and is rigidly connected to the first lead screw via a coupling or other components to achieve power transmission. Since the thread of the first lead screw passes through the slider, according to the principle of threaded transmission, the rotation of the lead screw is converted into horizontal linear movement of the slider on the slide rail, thereby driving the mounting box and projector to adjust their position in the horizontal direction.

[0014] When vertical adjustment is required, the second motor starts, and its output end drives the bidirectional threaded rod to rotate. The two rotating rings connected by threads on the bidirectional threaded rod will move towards or in opposite directions when it rotates due to the positive and negative thread sections of the bidirectional threaded rod. The connecting rod connected to the bottom of the rotating ring transmits the movement of the rotating ring to the mounting box, so that the mounting box rotates around the connection point with the connecting rod, thereby realizing the vertical angle adjustment of the projector. The limiting block at the bottom of the slider slides in the groove at the top of the rotating ring, which plays a guiding and stabilizing role and ensures the smooth movement of the rotating ring.

[0015] When the projector is not in use and is being stored away, the third motor starts, and its output drives the second lead screw to rotate. The thread of the second lead screw passes through the connecting block. According to the threaded transmission, the connecting block moves along the slide bar or the second lead screw inside the U-shaped frame under the rotation of the second lead screw, thereby causing the protective box to slide up and down along the outer wall of the mounting box. When the projector needs to be stored, the third motor drives the protective box to slide down and wrap around the projector; when the projector needs to be used, it drives the protective box to slide up.

[0016] As the protective box moves, the limiting groove on one side of the inner wall of the protective box contacts and moves relative to the limiting wheel on the transmission rod. The limiting groove guides the limiting wheel. Since the two transmission rods are rotatably set on one side of the mounting box through the rotating rod and the bottom end is rotatably connected to the sealing plate, when the limiting wheel moves under the action of the limiting groove, the transmission rod rotates around the rotating rod, causing the sealing plate to slide in the opening, thereby realizing the automatic opening and closing of the sealing plate.

[0017] Beneficial effects: In this utility model, the interactive linkage device based on a large space allows for precise horizontal and vertical adjustment of the projector position through the adjustment components, thereby improving the applicability of the projector in large spaces and meeting diverse projection needs.

[0018] In this utility model, a large-space multi-person interactive linkage device is described. The storage component can store the projector when it is not in use, preventing the projector from being corroded by dust and moisture, extending the service life of the projector, and at the same time, it can also resist accidental collisions to a certain extent and protect the precision internal components of the projector.

[0019] In this utility model, a multi-person interactive linkage device based on a large space is provided. When the protective box slides down to wrap the projector, the sealing plate automatically closes. When the projector needs to be used, the protective box slides up and the sealing plate automatically opens. No additional power is required, and the operation is convenient.

[0020] In this invention, the projector position can be precisely adjusted horizontally and vertically by the adjustment component, which improves the applicability of the projector in large spaces and meets diverse projection needs. The storage component stores the projector when it is not in use, preventing it from being corroded by dust and moisture and extending its service life. The transmission component enables the automatic opening and closing of the sealing plate without the need for additional power, making it easy to operate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to Figure 1-5An interactive device includes a high-strength aluminum alloy slide rail 1 (25×15mm cross-section, 2.5mm wall thickness) mounted on the ceiling. A slider 2 is slidably connected to the bottom of the slide rail 1, and an ABS engineering plastic mounting box 3 is connected to the bottom of the slider 2. A projector 4 is fixedly connected to the top inner wall of the mounting box 3. Through a series of components, this device enables flexible adjustment and secure storage of the projector 4 in a large space. The projector 4 is a JMGO N1S Ultra model. The structure and working principle of each component will be explained in detail below.

[0029] First, the device includes an adjustment assembly mounted on the slide rail 1 for adjusting the position of the slider 2. Specifically, the adjustment assembly includes a first lead screw 5, which is rotatably mounted inside the slider 2. A motor housing is fixedly connected to one side of the slide rail 1, and a first motor 6 is fixedly mounted inside the motor housing. The output end of the first motor 6 is fixedly connected to the first lead screw 5, which is threaded through the slider 2. When it is necessary to adjust the position of the slider 2 on the slide rail 1, the first motor 6 is activated. The first motor 6 drives the first lead screw 5 to rotate. Since the first lead screw 5 is threadedly connected to the slider 2, the rotation of the first lead screw 5 will drive the slider 2 to slide on the slide rail 1, thereby adjusting the position of the slider 2.

[0030] Furthermore, the adjustment assembly also includes a bidirectional threaded rod 7, which is rotatably mounted inside the slider 2. Two rotating rings 8 are threadedly connected to the bidirectional threaded rod 7, with each rotating ring 8 located on a different threaded section of the rod. A connecting rod 9 is rotatably connected to the bottom of each rotating ring 8, and the bottom ends of both connecting rods 9 are rotatably connected to the top of the mounting box 3. A second motor 10 is fixedly mounted on one side of the slider 2, and the output end of the second motor 10 is fixedly connected to the bidirectional threaded rod 7. When the vertical height of the projector 4 needs to be adjusted, the second motor 10 is activated, causing the bidirectional threaded rod 7 to rotate. Since two rotating rings 8 are threadedly connected to the different threaded sections of the bidirectional threaded rod 7, the rotation of the bidirectional threaded rod 7 will drive the two rotating rings 8 to move closer or further apart. The movement of the rotating rings 8 will cause the mounting box 3 to move up and down via the connecting rods 9, thereby adjusting the vertical height of the projector 4.

[0031] In addition, the device also includes a storage assembly, which is mounted on the mounting box 3 for storing and protecting the projector 4. Specifically, the storage assembly includes a polycarbonate protective box 12 (light transmittance >90%, thickness 2mm), which is slidably fitted onto the outer wall of the mounting box 3. Openings 122 are provided on both sides of the protective box 12, and nylon sealing plates 17 (including silicone sealing strips, Shore A hardness 50A) are slidably installed within each opening 122. U-shaped frames 13 are fixedly connected to both sides of the mounting box 3, and connecting blocks 14 are fixedly connected to both sides of the protective box 12. The two connecting blocks 14 extend into the interior of the corresponding U-shaped frames 13. A sliding rod is fixedly installed inside one U-shaped frame 13, passing through the corresponding connecting block 14 and slidably connected to it. A second lead screw 15 is rotatably installed inside the other U-shaped frame 13, and a third motor 16 is fixedly connected to the bottom of the other U-shaped frame 13. The output end of the third motor 16 is fixedly connected to the second lead screw 15, which is threaded through the corresponding connecting block 14.

[0032] When the projector 4 needs to be stored, the third motor 16 is activated, which drives the second lead screw 15 to rotate. Since the second lead screw 15 is threadedly connected to the corresponding connecting block 14, the rotation of the second lead screw 15 will drive the connecting block 14 to slide within the U-shaped frame 13. Simultaneously, since another connecting block 14 is slidably connected to the slide rod, this connecting block 14 will move along with the protective box 12. The movement of the two connecting blocks 14 will cause the protective box 12 to slide downwards, thereby covering the mounting box 3 and the projector 4.

[0033] This application can be used in the field of projection technology, or in other fields applicable to this application.

[0034] Example 2: Reference Figure 2-5 An improvement upon Embodiment 1: A large-space multi-person interactive linkage device applied to the field of projection technology. To prevent the rotating ring 8 from shifting during movement, a limiting block 11 is fixedly installed at the bottom of the slider 2. Grooves corresponding to the limiting blocks 11 are formed on the top outer walls of both rotating rings 8, and both grooves are slidably connected to the limiting blocks 11. The cooperation between the limiting blocks 11 and the grooves ensures the stability of the rotating rings 8 during movement.

[0035] To enable the automatic opening and closing of the two sealing plates 17, transmission assemblies are provided on both sides of the mounting box 3. Each transmission assembly includes two transmission rods 18, which are rotatably mounted on one side of the mounting box 3 via a common rotating rod. The bottom ends of the two transmission rods 18 are rotatably connected to the corresponding two sealing plates 17. A limiting wheel 19 is fixedly mounted on one side of each of the two transmission rods 18, and a limiting groove 121 is formed on the inner wall of one side of the protective box 12, with both limiting wheels 19 extending into the limiting groove 121.

[0036] As the protective box 12 slides downwards, the limiting wheel 19 will slide within the limiting groove 121. Due to the shape design of the limiting groove 121, when the protective box 12 slides to a certain position, the limiting wheel 19 will drive the transmission rod 18 to rotate. The rotation of the transmission rod 18 will cause the sealing plate 17 to slide within the opening 122, thereby realizing the automatic opening and closing of the sealing plate 17. When the protective box 12 completely covers the mounting box 3 and the projector 4, the sealing plate 17 will close the opening 122, providing storage and protection for the projector 4.

[0037] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 6, the second motor 10, and the third motor 16 are commonplace and are all conventional methods or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. In addition, the materials listed in this embodiment can also be selected from other materials as needed.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
