Description

Technical Field

[0001] This invention relates to the field of advertising technology, and specifically to an advertising system and advertising display method based on intelligent environmental recognition. Background Technology

[0002] With the development of advertising display technology, holographic projection advertising, due to its strong three-dimensional effect, novel visual effects, and rich display formats, has been gradually applied in scenes such as squares, shopping malls, and exhibition halls. Existing holographic projection advertising devices typically project advertising images onto a projection panel using a projector to create corresponding holographic visual effects, thereby enhancing the attractiveness and display effect of the advertising content.

[0003] However, the size of the projection panel in existing holographic projection advertising devices is usually fixed, and its effective projection area is difficult to adjust according to actual usage needs after the device is manufactured.

[0004] If a smaller projection panel is always used, when a larger advertising image needs to be displayed, the fixed-size projection panel is easily limited by the projection area, making it difficult to meet the needs of large-format advertising displays. However, if a large projection panel is used continuously, it will increase the overall space occupied by the device. Summary of the Invention

[0007] Optionally, the lifting mechanism includes a cylinder and a cross-shaped lifting plate. The cylinder is fixed to the base, and the cross-shaped lifting plate is fixed to the piston rod of the cylinder. The cross-shaped lifting plate abuts against all the extended projection plates.

[0008] Optionally, the limiting mechanism includes a threaded rod, a gear, and a limiting block with an inclined surface. The cross lifting plate has four threaded holes, a threaded rod is threaded into one of the threaded holes, the gear is fixed to the threaded rod, the limiting block with an inclined surface is slidably connected to the cross lifting plate, and the limiting block with an inclined surface has a limiting section. Four racks are fixed to the base.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] like Figures 1-6 As shown, an advertising system based on intelligent environmental recognition includes a control terminal and an advertising display device that are wirelessly connected to each other. The advertising display device includes a base 1 and an extended projection panel 4. A light sensor and a processing module are fixedly connected to the base 1. Four sets of guide mechanisms are fixedly connected to the base 1. The main projection panel 2 is connected to the guide mechanisms. A lifting projection mechanism and a supporting mechanism are connected to the base 1. An active shielding mechanism is connected to the lifting projection mechanism. Four limiting mechanisms are connected to the supporting mechanism. The extended projection panel 4 is detachably connected to the main projection panel 2.

[0023] Staff can use the control terminal to select the advertising content to be played, control the projector 21 to turn it on and off, and perform other operations.

[0024] The detachable combination of the main projection panel 2 and the extended projection panel 4 allows the area of ​​the projection medium to be changed according to the size of the advertising image. The lifting projection mechanism is used to adjust the projection position and height, the lifting mechanism is used to lift the extended projection panel 4 and the main projection panel 2, the movable shielding mechanism is used to shield the external light in the projection area, and the limiting mechanism is used to limit the combined projection medium to improve the stability during the projection process.

[0025] Based on the above scheme, in some embodiments, each group of the guiding mechanism includes two guide rails 6 fixed to the base 1, the guide rails 6 are provided with guide strips 7, the main projection plate 2 is provided with two limiting grooves 3, and the extended projection plate 4 is provided with two guide grooves 5.

[0026] The guide bar 7 cooperates with the limiting groove 3 and the guide groove 5 respectively to support and limit the main projection plate 2 laterally, and guide the movement direction of the extended projection plate 4.

[0027] In a preferred embodiment, the lifting mechanism includes a cylinder 8 and a cross-shaped lifting plate 10. The cylinder 8 is fixed to the base 1, and the cross-shaped lifting plate 10 is fixed to the piston rod of the cylinder 8. The cross-shaped lifting plate 10 abuts against all the extended projection plates 4.

[0028] When the piston rod of cylinder 8 extends, it can drive the cross lifting plate 10 to move upward. The cross lifting plate 10 simultaneously lifts the four extended projection plates 4, causing the extended projection plates 4 to move toward the main projection plate 2 and combine with the main projection plate 2, thereby expanding the area of ​​the projection medium. It can also continue to lift the combined projection medium as a whole to move upward, increasing the display height of the advertising image.

[0029] Furthermore, the limiting mechanism includes a threaded rod 13, a gear 14, and a limiting block 15 with an inclined surface. The cross lifting plate 10 has four threaded holes. A threaded rod 13 is threaded into one of the threaded holes. The gear 14 is fixed to the threaded rod 13. The limiting block 15 with an inclined surface is slidably connected to the cross lifting plate 10. The limiting block 15 with an inclined surface has a limiting section. Four racks 16 are fixed to the base 1.

[0030] After the cross-shaped lifting plate 10 moves up to the predetermined position, the gear 14 and the rack 16 mesh, causing the gear 14 to drive the threaded rod 13 to rotate. The threaded engagement between the threaded rod 13 and the threaded hole causes the threaded rod 13 to move horizontally, pushing the inclined limiting block 15 to move upward, so that its limiting section extends out of the top wall of the cross-shaped lifting plate 10, thereby limiting the extended projection plate 4 and preventing the projection medium formed by the extended projection plate 4 and the main projection plate 2 from moving horizontally.

[0031] Regarding the specific configuration of the lifting projection mechanism, the lifting projection mechanism includes guide columns 11, support columns 12, lifting seat 20 and projector 21. Two or more guide columns 11 are fixedly connected to the base 1. The support columns 12 are slidably connected to the base 1. The support columns 12 are fixedly connected to the piston rod on the cylinder 8. The lifting seat 20 is fixedly connected to the support columns 12. The lifting seat 20 is slidably connected to all guide columns 11. The projector 21 is fixedly connected to the bottom wall of the lifting seat 20.

[0032] When the piston rod of cylinder 8 extends, it can drive the lifting seat 20 to move steadily upward along the guide column 11 through the support column 12, thereby driving the projector 21 to move upward synchronously, so that the position of the projector 21 can be adjusted with the lifting of the projection medium, so that the projector 21 can project the image onto the raised projection medium.

[0033] In an optional embodiment, the shielding mechanism includes a truncated quadrangular body 17 and four baffles 18. The truncated quadrangular body 17 is fixedly connected to two of the guide columns 11. The baffles 18 are slidably connected to the top wall of the lifting seat 20. The baffles 18 are connected to the lifting seat 20 through springs 19. An inclined panel 181 is fixedly connected to the baffles 18.

[0034] When the lifting seat 20 moves upward, it causes the baffle 18 and the inclined panel 181 to move upward synchronously. After the inclined panel 181 abuts against the inclined side wall of the truncated pyramid 17, the inclined surface cooperation causes the baffle 18 to overcome the elastic force of the spring 19 and move outward of the lifting seat 20, so that the four baffles 18 automatically unfold and block the external light above the projection area. When the lifting seat 20 descends, the baffle 18 can be reset under the elastic force of the spring 19 to reduce the space occupied by the device in the non-expanded state.

[0035] Optionally, the baffle 18 is coated with a light-blocking coating. The light-blocking coating can improve the baffle 18's ability to block external light, reduce the interference of ambient light on the projected image, and thus improve the clarity and display effect of the projected image.

[0036] The piston rod on the cylinder 8 is fixedly connected to the support column 12 via the connector 9. The connector 9 is used to connect the piston rod of the cylinder 8 and the support column 12, so that the cylinder 8 can synchronously drive the cross lifting plate 10 and the support column 12 to move, thereby realizing the linkage between the projection medium lifting and the lifting of the lifting projection mechanism using the same cylinder 8.

[0037] The main projection plate 2 has a connecting groove 22, and the extended projection plate 4 has a protrusion 23, which is adapted to the connecting groove 22. When the extended projection plate 4 moves up to abut against the main projection plate 2, the protrusion 23 can be inserted into the corresponding connecting groove 22. Through the cooperation of the protrusion 23 and the connecting groove 22, the extended projection plate 4 and the main projection plate 2 are relatively positioned, so that the two are stably combined to form a projection medium with a larger area.

[0038] An advertising display method based on intelligent environment recognition utilizes an advertising system based on intelligent environment recognition to perform holographic projection of advertisements.

[0039] Implementation process: In the initial state, the base 1 is placed at the location where the advertisement needs to be projected. When the size of the advertisement to be projected is small, only the four main projection panels 2 are used as the projection medium. That is, the image played by the projector 21 is projected onto the four main projection panels 2. The outer walls of the two limiting grooves 3 and the two guide strips 7 on the main projection panels 2 abut against each other, thereby supporting and limiting the main projection panels 2. The four baffles 18 do not extend to the side of the lifting seat 20, reducing the space occupied by the device. The top wall of the limiting section on the inclined limiting block 15 is flush with the top wall of the cross lifting plate 10, preventing the inclined limiting block 15 from interfering with the movement of the extended projection panel 4.

[0040] When the advertising image to be projected is large, place the extended projection board 4 on the two guide rails 6, with the inner walls of the two guide grooves 5 and the outer walls of the two guide strips 7 abutting each other. All four extended projection boards 4 are placed in this way.

[0041] When cylinder 8 is activated, the piston rod on cylinder 8 extends, thereby causing the connecting piece 9, the cross lifting plate 10, and the support column 12 to move upward. The upward movement of the support column 12 causes the lifting seat 20 to move upward along all the guide columns 11, thereby causing the projector 21 and all the baffles 18 to move upward. The upward movement of the projector 21 facilitates the subsequent projection of the image. The upward movement of all the baffles 18 causes all the inclined panels 181 to move upward. The inclined panels 181 abut against the inclined side wall of the truncated pyramid 17, thereby causing the baffles 18 to overcome the elastic force of the spring 19 and move outward to the outside of the lifting seat 20. The baffles 18 can block the light above the lifting seat 20 and enhance the projection effect.

[0042] When the cross-shaped lifting plate 10 moves upward, it lifts four extended projection plates 4. The extended projection plates 4 move along the guide rail 6 until the top wall of the extended projection plate 4 abuts against the bottom wall of the main projection plate 2, thereby allowing the protrusion 23 to insert into the connecting groove 22 for limiting. Then, the cross-shaped lifting plate 10 continues to move upward, lifting all the extended projection plates 4 and all the main projection plates 2, causing the extended projection plates 4 and the main projection plates 2 to disengage from the guide rail 6 and move upward. Then, the gear 14 and the rack 16 mesh, and the rack 16 drives the gear 14 to rotate. This causes the threaded rod 13 to rotate. Since the threaded rod 13 and the threaded hole are threadedly engaged, the threaded rod 13 will move horizontally when it rotates. One end of the threaded rod 13 pushes the inclined surface of the inclined limiting block 15, thereby causing the inclined limiting block 15 to move upward. The top wall of the limiting section on the inclined limiting block 15 moves upward to above the top wall of the cross lifting plate 10. The limiting sections of the four inclined limiting blocks 15 limit the four extended projection plates 4, preventing the projection medium formed by the extended projection plate 4 and the main projection plate 2 from undergoing horizontal displacement.

[0043] In addition, a light sensor is used to detect the light intensity of the environment in which the advertising display device is located in real time, and sends the detected ambient light information to the processing module. The processing module analyzes and processes the ambient light information, and generates corresponding projection control information based on the ambient light intensity. The projection control information is then sent to the projector 21 to adjust the projection brightness of the projector 21. When the ambient light intensity is high, the projection brightness of the projector 21 is increased; when the ambient light intensity is low, the projection brightness of the projector 21 is decreased. This allows the brightness of the projected image to be adaptively adjusted according to changes in the surrounding ambient light, reducing the impact of changes in ambient light on the advertising display effect and avoiding energy waste caused by excessively high projection brightness when the ambient light is weak.

[0044] The beneficial effects of this invention are as follows: By setting up a main projection panel 2 and a detachable extended projection panel 4, the advertising display device can flexibly adjust the projection area according to the size of the advertising content. When the advertising content is small, only the main projection panel 2 is used for projection, reducing the overall space occupied by the device. When the advertising content is large, the cylinder 8 drives the cross lifting plate 10 to move upward, lifting the extended projection panel 4 and combining it with the main projection panel 2 to form a larger projection medium, thereby expanding the effective projection area and meeting the needs of large-format advertising displays. This solves the problem that existing projection panels have fixed sizes, making it difficult to meet large-format displays with small-sized panels, while using large-sized projection panels increases the space occupied by the device.

[0045] During the process of expanding the projection area, the cylinder 8 drives the cross-shaped lifting plate 10, the lifting seat 20, and the projector 21 to move upwards simultaneously, raising the overall projection medium formed by the main projection plate 2 and the extended projection plate 4. This increases the display height of the advertising image, allowing people at a greater distance or behind the crowd to see the projected content, thus expanding the visible range of the advertisement. Simultaneously, the baffle 18 moves upwards with the lifting seat 20 and extends outwards in conjunction with the inclined panel 181 and the truncated pyramid 17, blocking the light above the projection area to enhance the projection effect. Furthermore, the gear 14, after meshing with the rack 16, drives the threaded rod 13 to push the inclined limiting block 15 upwards, limiting the extended projection plate 4 and preventing horizontal displacement of the projection medium. Therefore, a single cylinder 8 can simultaneously complete the actions of expanding the projection area, raising the projection medium, blocking light, and limiting the projection plate, expanding the visible range of the advertisement while improving the stability and display effect of the large-format projection.
