The embodiments of the present invention will be described in detail below with reference to the drawings.

[0029] Embodiment 1

[0030] Please refer to Figures 1 to 8 , the present invention preferably provides a technical solution: a multimedia projection device for visual communication design, including: a substrate 111; two sets of gear-link transmission frames provided on the substrate 111, and a first support platform and a second support platform provided between the two sets of gear-link transmission frames. A first projection module and a second projection module are respectively arranged on the first support platform and the second support platform. Among them, the first projection module can be used as a cold-color lens, and the second projection module is used as a warm-color lens; when the two sets of gear-link transmission frames operate, the first projection module and the second projection module alternately switch up and down, back and forth, for the color tone overlap of the cold-color lens and the warm-color lens, generating a contrast and fusion effect, thereby enhancing the visual three-dimensional sense.

[0031] The first projection module and the second projection module provided in this application can be used as a cold-color lens and a warm-color lens respectively. Under the action of two sets of gear-link transmission frames, they overlap warm and cold color tones in an alternating manner of up and down, front and back, producing contrast and fusion effects, thereby achieving the effect of enhancing visual three-dimensional sense;

[0032] Specifically: Warm color tones such as orange and yellow usually give people a feeling of warmth and closeness; cold color tones such as blue and green appear calm and distant;

[0033] At the same time, the gear-link transmission frame set in this application, as Figure 8 shown, can realize the overlap of warm and cold projections (the overlap of superimposing warm and cold color tones) by adjusting the up and down, front and back alternating switching of the first projection module and the second projection module:

[0034] One way of expression is that when the second projection module acts alternately in front of the first projection module, the warm color tone of the warm-color lens dominates. The warm-color lens adjusts its position horizontally in the front and back direction, and at the same time the cold-color lens makes auxiliary up and down adjustments to achieve an appropriate light perception level. At this time, the projected range created shows: reducing the sense of distance, making the space appear more compact or warm, and is suitable for creating an intimate atmosphere in a small space;

[0035] Another way of expression is that when the second projection module acts alternately behind the first projection module, the cold color tone of the cold-color lens dominates. The cold-color lens adjusts its position up and down, and at the same time the warm-color lens makes auxiliary front and back adjustments horizontally to achieve an appropriate light perception level, that is, expanding the sense of space, making the environment appear open or cold, and is suitable for large spaces or places where calm thinking is needed;

[0036] The superposition of warm and cold projections is an artistic technique to enhance the three-dimensional sense of space through the contrast of light and shadow and colors. By superimposing the light and shadow of cold color tones (such as blue and green) and warm color tones (such as red and orange), rich layers and visual depth can be created, enhancing the three-dimensional sense and spatial hierarchy of objects;

[0037] And the gear-link transmission frame set in this application not only achieves the effect of enhancing visual three-dimensional sense through the process of the up and down, front and back alternating switching of the first projection module and the second projection module, but also enables the combination of warm and cold light to form different combinations in different application scenarios and have different projection effects;

[0038] For example: cold light background + warm light pattern: project a cold-color background light on the wall, and then superimpose a warm-color pattern or text to form a three-dimensional sense; warm light background + cold light texture: superimpose a cold-color texture projection on the warm-color background light to enhance the layering of the wall; secondly, the combination of warm and cold light divides the space: through the contrast of warm and cold light, different functional areas are divided, enhancing the spatial hierarchy;

[0039] This application uses a first projection module and a second projection module as cold and warm color lenses, combined with the design of alternately switching up and down and front and back between the two, to achieve the superposition of cold and warm projections. Moreover, the superposition of cold and warm projections can reasonably match the positions, intensities, and angles of cold and warm light sources according to space requirements and personal preferences, creating rich spatial levels and three-dimensional senses, while enhancing the overall visual effect and artistic atmosphere, and creating a unique light and shadow effect.

[0040] Further, two sets of gear-linkage drive frames are respectively placed at both ends of the substrate 111 and offset by a certain distance; each set of gear-linkage drive frames includes a connector detachably installed on the substrate 111, and a vertical rail 214 and a horizontal rail 215 provided on the connector. Vertical grooves 219 and horizontal grooves 220 are respectively formed inside the vertical rail 214 and the horizontal rail 215. Among them, the vertical rail 214 and the horizontal rail 215, and the vertical groove 219 and the horizontal groove 220 are both in a cross distribution and communicate with each other; and a first drive block 216 and a second drive block 217, a first support pillar 221 and a second support pillar 222 are respectively arranged inside the vertical rail 214 and the horizontal rail 215, and inside the vertical groove 219 and the horizontal groove 220. Among them, the first drive block 216 is fixed to the first support pillar 221, the second drive block 217 is fixed to the second support pillar 222, and the two first support pillars 221 are assembled diagonally and offset with the first support platform, and the two second support pillars 222 are assembled diagonally and offset with the second support platform; a meshing drive assembly is further included, which is used for alternately switching the first drive block 216 and the second drive block 217 up and down and front and back.

[0041] It is known that two sets of gear-linkage drive frames are respectively placed at both ends of the substrate 111 and offset by a certain distance, combined with Figure 2 、 3 As shown, the two first support pillars 221 are assembled diagonally and offset with the first support platform, and the two second support pillars 222 are assembled diagonally and offset with the second support platform, so that the two sets of vertical rails 214 and horizontal rails 215 on both sides of the substrate 111 are offset and distributed;

[0042] Here, combined with Figure 1 、 2 、5 shown, the vertical rail 214 and the horizontal rail 215, and the vertical groove 219 and the horizontal groove 220 are both in a cross distribution and communicate with each other. The first drive block 216 and the second drive block 217 provided inside the vertical rail 214 and the horizontal rail 215, and the first support pillar 221 and the second support pillar 222 provided inside the vertical groove 219 and the horizontal groove 220 are respectively fixedly connected. Therefore, when the first drive block 216 and the second drive block 217 alternately switch up and down and front and back through the meshing drive assembly, the first support platform and the second support platform simultaneously switch up and down and front and back.

[0043] Further, the meshing transmission assembly includes a mounting frame 611 fixed to the upper surface of the substrate 111, a mounting sleeve 612 provided at the top of the mounting frame 611, and a rotating shaft provided in the mounting sleeve 612. One end of the rotating shaft is sequentially provided with a swing rod 614 and a first transmission gear 613. The first transmission gear 613 is fixed to the rotating shaft, and the swing rod 614 is rotatably mounted on the rotating shaft; and a second transmission gear 615 disposed outside the swing rod 614 and meshing with it. A pin shaft is rotatably mounted in the middle of the second transmission gear 615. One end of the pin shaft is rotatably mounted on the end of the swing rod 614 away from the rotating shaft, and the other end is fixed with a transmission rod 616. The two ends of the transmission rod 616 are respectively rotatably mounted with the first transmission block 216 and the second transmission block 217 through a mounting shaft. When the rotating shaft rotates, the second transmission gear 615 orbits and rotates around the outer periphery of the swing rod 614 at the same time, realizing the alternating switching of the first transmission block 216 and the second transmission block 217 up and down, front and back; it further includes a driving assembly for driving the two rotating shafts to rotate at the same frequency and the same speed.

[0044] It is known that the first transmission gear 613 is fixed to one end of the rotating shaft, and the second transmission gear 615 rotatably mounted on the swing rod 614 rotatably mounted at this end of the rotating shaft is disposed outside the swing rod 614 and meshes with it. At the same time, the pin shaft rotatably mounted in the middle of the second transmission gear 615 is fixed to the transmission rod 616 connected between the first transmission block 216 and the second transmission block 217. Therefore, when the first transmission gear 613 rotates, it drives the second transmission gear 615 to orbit and rotate around its outer periphery. Since the position of the second transmission gear 615 changes, it drives the transmission rod 616 to move synchronously, that is, drives the first transmission block 216 up and down inside the vertical rail 214, while the second transmission block 217 moves back and forth inside the horizontal rail 215, and the up and down, front and back alternate operation further realizes the alternating switching of the first and second support platforms up and down, front and back, completing the superimposed design of the cold and warm projections.

[0045] Further, the driving assembly includes two support blocks 711 disposed at both ends of the middle of the substrate 111. A rotatable connecting rod 716 is installed through between the two support blocks 711, and second transmission wheels 713 are respectively fixed to both ends of the connecting rod 716; and first transmission wheels 714 are respectively fixed to the opposite ends of the two rotating shafts. A transmission belt 715 is sleeved between the first transmission wheel 714 and the second transmission wheel 713 on the same side; it further includes a support provided on the substrate 111, and a driving motor 712 is provided on the support. The output end of the driving motor 712 is fixed to the second transmission wheel 713 close to it.

[0046] Combined Figure 1 、 2As shown in FIGS. 5, the two rotating shafts are respectively connected to both ends of the connecting rod 716 through the second transmission wheels 713, the first transmission wheels 714 and the transmission belts 715. At the same time, the driving motor 712 is fixed to the second transmission wheel 713 on its side. Therefore, when the driving motor 712 operates, the two rotating shafts can rotate at the same frequency, the same speed and in the same direction, ensuring the operation process of the first and second support platforms at the same frequency and the same speed.

[0047] Furthermore, the mounting member includes a mounting plate 211 and a mounting groove 212 formed in the mounting plate 211. A bolt 213 is provided in the mounting groove 212. When the bolt 213 passes through the mounting groove 212 and is connected to the threaded hole formed in the substrate 111, it is used for locking the mounting plate 211 and the substrate 111. Combining Figure 1 、 2 As shown in FIGS., the provided mounting member facilitates the detachable mounting of the gear link transmission frame and the substrate 111.

[0048] Embodiment 2

[0049] As another embodiment of the present invention, the first support platform has the same structure as the second support platform. Among them, the first support platform includes a support plate 218, the support plate 218 is obliquely diagonally connected to two first support columns 221, and a track assembly provided on the support plate 218 for the horizontal and vertical movement of the first projection module; the track assembly includes a first slide rail 311 fixed to the inner side of the groove of the support plate 218, a first slider 312 slidably mounted on the first slide rail 311, and a mounting block 313 fixed to the support plate 218. An electric telescopic rod 314 connected to the first slider 312 is fixed on the mounting block 313, which serves as a power source for the horizontal movement of the first slider 312; it also includes a second slide rail 315 fixed to the first slider 312, a second slider 316 slidably mounted on the second slide rail 315 for the assembly of the first projection module; and a threaded groove formed on the back side of the second slide rail 315. A screw 317 is provided in the threaded groove. When the screw 317 passes through the threaded groove and abuts against the second slider 316, it is used for locking the position of the second slider 316.

[0050] In this embodiment, combining Figure 1 、 2 As shown in FIGS. 6 and 7, the first projection module is assembled on the second slider 316, and the second slider 316 is slidably mounted on the second slide rail 315 and locked by the screw 317. The second slide rail 315 is fixed to the first slider 312, and the first slider 312 is slidably mounted on the first slide rail 311 and horizontally moved by the electric telescopic rod 314. Therefore, through the horizontal movement of the first slider 312 and the vertical movement of the second slider 316, the position of the first projection module is adjusted, and thus it is convenient to adjust the projection angle and position of the first projection module.

[0051] Embodiment 3

[0052] As other embodiments of the present invention, the first projection module includes a first adjustment bracket and a first projector 511 disposed at the operating end of the first adjustment bracket; the second projection module is composed of a second adjustment bracket having the same structure as the first adjustment bracket and a second projector 512 connected to the second adjustment bracket; further, the first adjustment bracket includes a connecting shaft 412 fixed to the side wall of the bottom of the second slider 316, and a swing arm 411 rotatably mounted on the connecting shaft 412. The bottom of the front end of the swing arm 411 is rotatably mounted with a first projector 511 through a positioning shaft; it further includes a first adjustment frame and a second adjustment frame, which are respectively used for adjusting the pitching angle and the lateral turning angle of the first projector 511; the first adjustment frame includes a mounting frame 413 fixed to the side wall of the top of the second slider 316, and a first motor 414 longitudinally fixed to the mounting frame 413. A first screw rod 415 is fixed to the output end of the first motor 414, and a first nut 416 is threadedly connected to the first screw rod 415; it further includes a first mounting member 417 fixed to the swing arm 411, and a first hinge rod 418 is hinged between the first mounting member 417 and the first nut 416; further, the second adjustment frame includes a second motor 419 horizontally fixed to the front end of the swing arm 411, and a second nut 421 is threadedly connected to a second screw rod 420 fixed to the output end of the second motor 419; it further includes a second mounting member 422 fixed to the front side of the first projector 511, and a second hinge rod 423 is hinged between the second mounting member 422 and the second nut 421.

[0053] In this embodiment, the swing arm 411 is rotatably mounted on the bottom of the second slider 316 through the connecting shaft 412, and the first adjustment frame and the second adjustment frame respectively disposed on the rear side and the front side of the swing arm 411 can adjust the pitching angle and the lateral turning angle of the first projector 511 rotatably mounted on the bottom of the front end of the swing arm 411 through the positioning shaft, which further facilitates expanding the projection angle of the first projector 511 or the second projector 512, so as to adjust the range of the first projection module and the second projection module overlapping up and down and front and back. According to the superposition of cold and warm projections, the positions, intensities and angles of the cold and warm light sources can be reasonably matched according to the space requirements and personal preferences, creating a rich spatial hierarchy and three-dimensional sense. Here, the first projector 511 or the second projector 512 is a mature existing technology and will not be elaborated;

[0054] Combined with Figure 6 、 7 As shown, the first nut 416 sleeved on the first screw rod 415 is hinged to the first mounting member 417 on the swing arm 411 through the first hinge rod 418. Therefore, when the first motor 414 is driven to operate, the first nut 416 can be longitudinally moved, so as to pull the swing arm 411 to perform pitching adjustment with the connecting shaft 412 as the axis;

[0055] Similarly, when the second motor 419 operates, the second screw sleeve 421 can be horizontally moved. During this process, the second screw sleeve 421 can drive the second mounting member 422 on the first projector 511 to rotate circumferentially around the positioning shaft at the front end of the swing arm 411 through the second hinge rod 423;

[0056] With this design, by providing the first adjustment frame and the second adjustment frame, the projection angle of the first projector 511 or the second projector 512 is extended by adjusting the pitching angle and the horizontal turnover angle of the first projector 511.
