Description

Technical Field

[0001] This utility model relates to the field of advertising machine technology, specifically to an advertising machine extension device. Background Technology

[0002] Existing advertising machines typically consist of only basic components such as a display screen, motherboard, touchscreen, and power supply, offering limited functionality and serving as passive information display terminals. These devices lack scalability in their hardware architecture, making them unsuitable for supporting virtual human applications requiring complex perception and interaction capabilities. Key modules needed to implement virtual human services, such as human body sensors, cameras, and microphone arrays, lack both pre-existing interfaces and integration solutions in current advertising machine designs, hindering their intelligent upgrades.

[0003] Furthermore, commercial advertising displays typically have large sizes (e.g., 43 to 65 inches). Simply adding the aforementioned sensing peripherals to the top and bottom bezels of the device will result in interaction failures due to severe ergonomic flaws: cameras will fail to capture facial information properly due to excessive tilt angles, microphones will have poor sound pickup due to excessive distance, and human body sensors may fail to detect users due to misaligned detection areas. This installation method prevents the sensors from being in their optimal working positions, ultimately causing a sharp drop in the reliability of the virtual human system's core functions such as wake-up, recognition, and dialogue. Utility Model Content

[0004] To address the technical problems existing in the background art described above, this utility model provides an advertising machine extension device.

[0005] The technical solution of this utility model is as follows: An advertising machine extension device includes: The functional component includes a vertically arranged box body, which has a front side panel and a rear side panel, and the rear side panel has mounting holes. The adapter is a hollow right-angle structure. The first end of the adapter passes through the mounting hole and is rotatably connected to the functional component through the damping shaft. The second end of the adapter is used to detachably connect to the side frame of the advertising machine. Both the first and second ends of the adapter are provided with wire through holes. The box contains a microphone array main board, a human body sensor, and a camera. A microphone head board is plugged into the microphone array main board, and the front panel has openings corresponding to the microphone head board's pickup surface, the human body sensor's sensing window, and the camera's lens. The microphone array motherboard, human body sensor, and camera are all electrically connected to the motherboard module inside the advertising machine via their respective compatible cables. The hollow channel inside the adapter allows the cables to be run through.

[0006] The specific structure of the damping shaft is as follows: two sets of damping shafts are symmetrically arranged on the top and bottom. The damping shaft includes a rotating shaft and a fixed shaft that are rotatably connected. The end of the rotating shaft away from the fixed shaft is fixedly connected to the box body through a connecting post. The end of the fixed shaft away from the rotating shaft is connected to one side of the first end of the adapter through a first connecting piece.

[0007] Furthermore, the microphone elements on the microphone board are arranged in an array.

[0008] Preferably, the human body sensing device is an infrared sensor or a millimeter-wave radar.

[0009] The adapter has the following structure: it includes a vertically connected and integrally formed installation section and a connecting section. The first end is located on the installation section, and the second end is located on the connecting end. Both the installation section and the connecting section are connected to the side frame of the advertising machine through multiple second connectors.

[0010] To allow the functional component housing to have a large range of rotation, the length and width of the mounting hole are both greater than the length and width of the mounting section, and the width of the mounting hole is 1.5-2 times the width of the mounting section.

[0011] To facilitate cable installation, a cable-passing groove is provided on the outside of the connecting section, which communicates with the cable-passing hole. One end of the cable-passing groove extends to a position close to the installation section.

[0012] Furthermore, the axis of the damping shaft is set vertically, and the rotation angle range of the functional component is 30°-120°.

[0013] The beneficial effects of this utility model are as follows: By designing independent functional components, the microphone array motherboard (including the microphone head board), human body sensor, and camera, all necessary for virtual human interaction, are highly integrated into a vertically oriented box. A standardized functional module is formed by uniformly opening adaptable sections on the front panel. This module is detachably connected to the side frame of the advertising machine via an adapter, allowing existing advertising machines to quickly acquire intelligent sensing and interaction capabilities without complex internal modifications, significantly reducing upgrade costs and technical barriers. The damping shaft's axis is vertically oriented, allowing the functional components to rotate in the horizontal plane (rotation angle range optimized to 30°-120°). This rotation method ensures that the camera, human body sensor, and microphone array integrated into the functional components are directly facing the user in front of the advertising machine, effectively avoiding problems such as image distortion, blind spots, and poor sound pickup caused by mounting them on the top or bottom of the device in existing technologies. The adapter is a hollow right-angle structure that houses all cables within its internal channel. Cables are led out from the through-hole at the end and a cable groove connected to the through-hole is provided on the outside of the connecting section. This allows for easy installation or maintenance without the need for laborious cable pulling from the end; cables can be directly placed into the groove from the side. Attached Figure Description

[0015] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an advertising machine extension device includes: The functional component includes a vertically arranged box 1, which has a front side plate 101 and a rear side plate 102. The rear side plate 102 is detachably connected to the box 1 and has a mounting hole 1021. The adapter is a hollow, right-angled structure. Its first end 202 passes through the mounting hole 1021 and is rotatably connected to the functional component via the damping shaft 3. The second end 204 is detachably connected to the side frame of the advertising machine 7. Both the first end 202 and the second end 204 of the adapter have through holes 205. To facilitate cable routing, the outer side of the connecting section 203 has a cable groove 206 communicating with its through holes 205. One end of the cable groove 206 extends to a position close to the mounting section 201.

[0016] See Figure 5 and Figure 6As shown, the box 1 contains a microphone array main board 8, a human body sensor 9, and a camera 10. A microphone board is plugged into the microphone array main board 8. The microphone elements on the microphone board are arranged in an array. The front panel 101 has openings 1011 corresponding to the pickup surface of the microphone board, the sensing window of the human body sensor 9, and the lens of the camera 10.

[0017] The microphone array motherboard 8, the human body sensor 9, and the camera 10 are all electrically connected to the motherboard module inside the advertising machine 7 via their respective compatible cables. The hollow internal channel of the adapter allows the cables to pass through, and the side frame of the advertising machine 7 has through holes for the cables. The adapter is designed as a hollow, right-angled structure, accommodating all cables within its internal channel. Cables are led out from the through hole 205 at the end, and a cable groove 206 communicating with the through hole 205 is provided on the outside of the connecting section 203. This allows for easy installation or maintenance, eliminating the need for laborious cable pulling from the end; cables can be directly placed into the groove from the side, simplifying the operation. It should be noted that the microphone array motherboard 8, the human body sensor 9, and the camera 10 are all existing technologies. The human body sensor 9 is an infrared sensor or millimeter-wave radar. The human body sensor 9 first detects the user's approach and wakes the system from standby mode. Then, the camera 10 starts up, captures the user's facial information for preliminary analysis, and defines the user profile. At the same time, the microphone array motherboard 8 enters working mode, ready to pick up the user's voice questions. After the user speaks, the microphone array accurately picks up the sound, the voice data is processed and AI generates a response, which is finally fed back to the user through a virtual human image and voice feedback.

[0018] The damping shaft 3 is a straight-line type, which is existing technology. The specific structure of the damping shaft 3 is as follows: two sets of damping shafts are symmetrically arranged vertically. Each damping shaft 3 includes a rotating shaft 301 and a fixed shaft 302 that are rotatably connected. The end of the rotating shaft 301 away from the fixed shaft 302 is fixedly connected to the housing 1 via a connecting post 4. The end of the fixed shaft 302 away from the rotating shaft 301 is connected to one side of the first end 202 of the adapter via a first connecting piece 5. The use of two sets of symmetrically arranged damping shafts 3, composed of components such as the rotating shaft 301 and the fixed shaft 302, provides uniform and stable rotational damping. Combined with the fact that the length and width of the mounting hole 1021 are both larger than the cross-sectional dimensions of the mounting section 201, this not only ensures that the functional component has a sufficiently large rotation range to cover a wider interaction area, but also ensures the smoothness and durability of the rotation process, allowing the functional component to stably remain at any adjustment angle and preventing displacement due to its own weight or slight contact.

[0019] See Figure 3 and Figure 7As shown, the adapter includes a vertically connected and integrally formed mounting section 201 and connecting section 203. The first end 202 is located on the mounting section 201, and the second end 204 is located on the connecting end. Both the mounting section 201 and the connecting section 203 are connected to the side frame of the advertising machine 7 through multiple second connectors 6.

[0020] To allow the housing 1 of the functional component to have a large range of rotation, the length and width of the mounting hole 1021 are both greater than the length and width of the mounting section 201, and the width of the mounting hole 1021 is 1.5-2 times the width of the mounting section 201.

[0021] The damping shaft 3 has its axis set vertically, and the rotation angle range of the functional components is 30°-120°. The vertical axis setting of the damping shaft 3 allows the functional components to rotate in the horizontal plane, enabling the camera 10, human body sensor 9, and microphone array integrated on the functional components to face the user located in front of the advertising machine 7. This effectively avoids problems such as image distortion, blind spots, and poor sound pickup caused by the installation of the device on the top or bottom in existing technologies.
