Description

Technical Field

[0001] This utility model relates to the field of science popularization equipment technology, specifically a knowledge question-and-answer machine based on intelligent AI. Background Technology

[0002] Currently, AI-based knowledge question-answering machines are intelligent systems integrating technologies such as natural language processing, knowledge graphs, and machine learning. They can understand the intent behind a user's natural language questions, retrieve information from a knowledge base, and generate answers through logical reasoning, supporting multi-turn dialogues and contextual understanding. Application scenarios include intelligent customer service answering inquiries, assisting learning in education, and providing health advice in healthcare. Compared to traditional question-answering systems, they are not simply keyword matching but possess semantic understanding and reasoning capabilities, enabling them to respond to user needs more accurately and naturally. They serve as intelligent tools for handling knowledge queries in human-computer interaction.

[0003] Existing knowledge-based question-and-answer machines have significant shortcomings in use: First, the human-computer interaction experience is poor. The fixed-height display screen cannot adapt to users of different heights, which may cause the user to look down or up during operation, leading to fatigue after long-term use. Furthermore, it cannot meet the usage needs of different scenarios (such as standing and sitting postures). Second, the equipment is not safe enough. The display screen lacks reliable support during lifting, raising, or maintenance. If mechanical failure or human error occurs, the display screen may collide with the base and be damaged.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides a technical solution: Example 1 Combination Figures 1 to 3A knowledge-based question-and-answer machine based on intelligent AI includes a base 3, an intelligent device display screen 4 on the top of the base 3, lifting mechanisms 1 on the left and right sides of the intelligent device display screen 4, and a support mechanism 2 on the top of the base 3.

[0020] The lifting mechanism 1 includes a drive assembly 11 and a transmission assembly 12. The drive assembly 11 is located on the left and right sides of the smart device display screen 4, and the transmission assembly 12 is located inside the drive assembly 11.

[0021] The drive assembly 11 includes a column 1101, which is disposed on the left and right sides of the smart device display screen 4. The column 1101 is fixedly connected to the top of the base 3. A human body sensing module 1102 is fixedly connected to the front side of the column 1101. A drive motor 1103 is fixedly connected to the top of the column 1101. A threaded shaft 1104 is fixedly connected to the bottom of the drive motor 1103. The threaded shaft 1104 is rotatably connected to the top of the base 3. The human body sensing module 1102 is electrically connected to the drive motor 1103. The transmission assembly 12 includes a threaded cylinder 1201, which is threadedly connected to the outer ring of the threaded shaft 1104. A connecting plate 1202 is fixedly connected to the inner side of the outer ring of the threaded cylinder 1201. The connecting plate 1202 is slidably connected to the inner side of the column 1101. The connecting plate 1202 is fixedly connected to the left and right sides of the smart device display screen 4.

[0022] Furthermore, human body sensing modules 1102 are evenly distributed on the front side of the column 1101. They sense the height of the person in front using infrared signals. Based on the feedback information from the human body sensing modules 1102, the drive motor 1103 is controlled to start rotating in both directions, thus adjusting the height of the smart device display screen 4. This allows the display screen 4 to automatically adjust to a suitable height for users of different heights. Each human body sensing module 1102 is fixed to the front side of the column 1101, arranged vertically at equal intervals, with each sensor corresponding to a fixed installation height. When the user is standing, all sensors within the body's height range are triggered to output a high level. The system uses the installation height of the highest trigger sensor as the basis for determining the user's height range, and combined with the current height position of the display screen, determines whether the drive motor 1103 rotates forward, reverses, or stops.

[0023] Example 2 See Figures 1 to 4 Furthermore, based on Embodiment 1, the support mechanism 2 includes a base pad assembly 21, a fixing assembly 22, and a reinforcing assembly 23. The base pad assembly 21 is disposed on the top of the base 3, the fixing assembly 22 is disposed on the bottom of the base pad assembly 21, and the reinforcing assembly 23 is disposed on the rear side of the drive assembly 11.

[0024] The base assembly 21 includes a pad 2101, which is positioned directly below the display screen 4 of the smart device. The bottom of the pad 2101 is in contact with the top of the base 3. Locking blocks 2102 are fixedly connected to the left and right sides of the bottom of the pad 2101, and the locking blocks 2102 are engaged within the base 3. The fixing assembly 22 includes a locking bracket 2201, which is fixedly connected to the center of the bottom of the pad 2101 and engaged within the base 3. 1. Sleeves 2202 are provided on the front and rear sides. Sleeves 2202 are fixedly connected to the top of the base 3. Bolts 2203 are fitted on the inner ring of sleeves 2202. Bolts 2203 are threadedly connected to the inner ring of bracket 2201. The reinforcement component 23 includes a reinforcement arm 2301. The reinforcement arm 2301 is fixedly connected to the top of the rear side of column 1101. A support rod 2302 is fixedly connected to the bottom of the reinforcement arm 2301. The support rod 2302 is fixedly connected to the top of the base 3.

[0025] Furthermore, the pad 2101 is positioned directly below the smart device display screen 4 to support it. During inspection or maintenance, the smart device display screen 4 can be lowered to the top of the pad 2101 for support. Simultaneously, during the downward movement of the smart device display screen 4, its bottom will not collide with the top of the base 3, thus improving the safety of the smart device display screen 4 during use.

[0026] Human body sensing module reference: Model / SB312A-01-001-L Operating voltage: DC 3.5V~12V Output mode / 3V high / low level output Static current / ≤20uA Delay time / 2 seconds is not adjustable Operating temperature: -20℃~55℃ Sensing range / angle ≤ 110 degrees cone angle; distance ≤ 4 meters PCB dimensions: 10*8mm Detailed URL: https: / / www.nysenba.com / pir-mod / sb312a-01-001-l.html In actual operation, when this device is used, the user stands in front of the smart device display screen 4. At this time, the human body sensing modules 1102 on both sides scan the height information of the person in front and calculate whether an adjustment is needed based on the current height of the smart device display screen 4. When adjustment is needed, the human body sensing module 1102 controls the start of the drive motors 1103 on both sides. The start of the drive motors 1103 drives the threaded shaft 1104 to rotate. The rotation of the threaded shaft 1104 drives the threaded cylinder 1201 to move up and down. The up and down movement of the threaded cylinder 1201 drives the smart device display screen 4 to move up and down through the connecting plate 1202 until the smart device display screen 4 moves to the appropriate height. At this time, the drive motors 1103 on both sides are turned off, and the height adjustment of the smart device display screen 4 is completed. The connecting plate 1202 and the inner sliding groove of the column 1101 form a sliding constraint pair. During the process of the threaded cylinder 1201 moving up and down driven by the threaded shaft 1104, the connecting plate 1202 slides along the inner guide groove of the column, constraining the lifting motion to the vertical straight direction, eliminating the radial deflection that may be generated in the threaded transmission, thereby ensuring smooth movement and preventing jamming. When it is necessary to disassemble the pad 2101, the worker first rotates the bolt 2203. The bolt 2203 rotates and moves forward within the inner ring of the bracket 2201. The bolt 2203 moves forward and disengages from the connection between the sleeve plate 2202 and the bracket 2201. At this time, the locking of the pad 2101 is released. Then, the worker can move the pad 2101 upward. The upward movement of the pad 2101 drives the bracket 2201 and the pad 2102 to move upward. The upward movement of the pad 2102 and the bracket 2201 disengages from the base 3. At this time, the disassembly of the pad 2101 is completed.
