Detailed Implementation

[0013] 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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: In this technical solution, a hotel digital interactive screen with identity recognition function includes an interactive touch display screen 1. The left end of the interactive touch display screen 1 is fitted with a protective shell a2, and the right end is fitted with a protective shell b3. An angle adjustment mechanism 4 is assembled on the rear side wall of the protective shell a2 and the protective shell b3. Arc-shaped plate grooves 8 are opened at the center of the opposite side wall of the protective shell a2 and the protective shell b3, and arc-shaped rod grooves 9 are opened at the center of the rear side wall of the protective shell a2 and the protective shell b3, respectively. The arc-shaped rod grooves 9 and the arc-shaped plate grooves 8 are connected. The angle adjustment mechanism 4 includes a fixing plate a10 and a fixing plate b12. A fixing rod a11 is vertically installed at the front end of the fixing plate a10, and a fixing rod b14 is vertically installed at the front end of the fixing plate b12. The fixing plate a10 is inserted into the arc-shaped plate groove 8, and the fixing rod a111 is set in the arc-shaped rod groove 9.

[0015] The interactive touch display screen 1 is the core interactive component of the entire system, used to present various types of information and receive user touch operation commands. It typically employs capacitive touch technology, featuring high sensitivity and precise touch response. This technology can quickly recognize user actions such as clicks, swipes, and zooms, providing a smooth interactive experience. Screen size can be selected based on the hotel's actual usage scenario and installation location. Common sizes include 21.5 inches and 27 inches. Taking a 21.5-inch screen as an example, its resolution is generally 1920×1080, which can clearly display various text, images, and video information. The display brightness is usually between 300-500 nits (cd / m²), ensuring that users can clearly see the screen content even in complex lighting environments such as hotel lobbies. The screen glass can be made of Corning Gorilla Glass, which has high hardness and scratch resistance, effectively protecting the screen from scratches and damage during daily use. Simultaneously, the screen supports multi-touch; generally, to meet diverse user needs, this interactive touch display should support at least 10-point touch. Protective shells a2 and b3 are designed to provide comprehensive physical protection for the interactive touch display 1. They can be made of high-strength engineering plastics, such as polycarbonate (PC), which has good impact resistance and can effectively reduce damage to the display from external impacts. Additionally, the interior of the protective shells typically includes cushioning pads, such as silicone pads, to further enhance the protective effect. The thickness of the protective shell can be determined according to actual needs, generally between 3 and 5 millimeters. Taking a 4-millimeter-thick polycarbonate protective shell as an example, simulation tests have shown that when subjected to an impact of 10 joules of energy, it can reduce the impact force transmitted to the display screen by more than 80%, greatly improving the impact resistance of the display screen. The protective case surface can be coated with an anti-fingerprint and anti-oil coating for easy daily cleaning and maintenance; The angle adjustment mechanism 4 is a key component for enabling multi-angle adjustment of the interactive touch display screen. It can meet the viewing and operation angle needs of users of different heights and in different usage scenarios. This mechanism achieves flexible rotation and positioning of the screen through a specific mechanical structure design. The angle adjustment mechanism 4 can typically adjust the angle between 0 and 90 degrees. For example, in a hotel lobby, the screen can be adjusted to an angle of about 70 degrees with the ground to facilitate operation by standing users; while in some scenarios where users need to operate while seated, such as a hotel business center, the screen can be adjusted to an angle of about 45 degrees with the tabletop to provide a comfortable viewing and operating angle. The arc-shaped plate groove 8 and the arc-shaped rod groove 9 are important structures that work in conjunction with the angle adjustment mechanism 4. The fixing plate a10 is inserted into the arc-shaped plate groove 8, and the fixing rod a11 is set in the arc-shaped rod groove 9. This structural design allows the angle adjustment mechanism 4 to move along an arc-shaped trajectory when adjusting the screen angle, thereby achieving smooth and precise angle adjustment. The radii of the curved plate groove 8 and the curved rod groove 9 can be designed according to the screen size and adjustment angle range. Taking a common 27-inch screen as an example, the radii of the curved plate groove 8 and the curved rod groove 9 can be designed to be 100-150 mm. This size can ensure both the flexibility of angle adjustment and the stability of the structure. Fixed plates a10 and b12 serve as the main connecting components of the angle adjustment mechanism 4, transmitting force and providing support. Fixed plate a10 is connected to the protective shell a2 via fixed rod a11, and fixed plate b12 is connected to the external mounting structure (such as a wall or mounting bracket) via fixed rod b14. When the screen angle needs to be adjusted, rotating fixed plate a10 moves fixed rod a11 within the arc-shaped groove 9, thereby changing the screen angle. Fixing plates a10 and b12 can be made of aluminum alloy, a material known for its high strength and light weight. For example, a 5mm thick aluminum alloy fixing plate can have a tensile strength of 200-300 MPa, sufficient to withstand the various forces generated during screen adjustment. The diameters of fixing rods a11 and b14 can be designed according to the actual stress conditions, generally between 8-12 mm.

[0016] In some technical solutions, a ball sleeve 17 is provided at the end of the fixed rod a11, and a ball 15 is installed at the end of the fixed rod b14. A rotating cavity 16 is provided inside the ball sleeve 17, and the ball 15 is assembled in the rotating cavity 16.

[0017] The combined design of the ball sleeve 17 and the sphere 15 allows the angle adjustment mechanism 4 to not only adjust the screen angle but also provide a certain degree of omnidirectional rotation. This design allows for fine-tuning of the screen in both horizontal and vertical directions, further enhancing the user experience. For example, when operating the screen from different positions, this omnidirectional rotation function allows the screen to be adjusted to the optimal viewing and operating angle. The diameter of the sphere 15 can be matched with the size of the rotating cavity 16 of the ball sleeve 17. Generally, the diameter of the sphere 15 is 0.5-1 mm smaller than the inner diameter of the rotating cavity 16 to ensure that while achieving flexible rotation, there will not be excessive wobbling. The ball sleeve 17 and the sphere 15 can be made of wear-resistant metal materials, such as stainless steel. After surface treatment, their wear resistance can be further improved, ensuring that the rotation function remains smooth during long-term use.

[0018] In some technical solutions, the rotating cavity 16 and the sphere 15 are fitted with a clearance.

[0019] A clearance fit means that the inner diameter of the rotating cavity 16 is slightly larger than the outer diameter of the sphere 15. This fit allows the sphere 15 to rotate freely within the rotating cavity 16 while ensuring a certain degree of coaxiality and stability. This fit not only meets the flexible adjustment needs of the screen in different directions, but also ensures that during use, there will be no difficulty in rotation due to an overly tight fit, or excessive shaking due to an overly loose fit. Typically, the gap between the rotating cavity 16 and the sphere 15 can be controlled between 0.1 and 0.3 mm. For example, when the diameter of the sphere 15 is 15 mm, the inner diameter of the rotating cavity 16 can be designed to be 15.2 mm. Such a gap can ensure the smooth rotation of the sphere 15 and, to a certain extent, avoid wobbling caused by an excessive gap.

[0020] In some technical solutions, the outer wall of the fixing plate b12 is provided with four mounting holes 13 along its axis.

[0021] The four mounting holes 13 are designed primarily to facilitate the fixed connection of the fixing plate b12 to the external mounting structure. By using bolts, nuts, and other connectors passing through the mounting holes 13, the fixing plate b12 can be securely installed on the wall, mounting bracket, or other structures, thereby achieving stable installation of the entire angle adjustment mechanism 4 and the interactive touch display screen 1. The diameter of the mounting hole 13 can be determined according to the bolt specifications used. Common bolt specifications are M6, M8, etc., and the corresponding mounting hole 13 diameter can be designed to be 7-9 mm. The four mounting holes 13 are evenly distributed on the outer wall of the fixing plate b12, which can ensure that the fixing plate b12 is subjected to uniform force after installation and improve the stability of the installation.

[0022] In some technical solutions, elastic rods 6 are installed at both the upper and lower ends of the side wall of protective shell a2, slots are opened at both the upper and lower ends of the side wall of protective shell b3, and buckle grooves 5 are opened at the slots on both the upper and lower side walls of protective shell b6. Elastic blocks 7 are provided at the ends of the elastic rods 6, the elastic rods 7 are inserted into the slots, and the elastic blocks 7 are set in the buckle grooves 5.

[0023] This structure, consisting of the elastic rod 6, slot, latch 5, and elastic block 7, is primarily used to achieve a quick, convenient, and secure connection between protective shell a2 and protective shell b3. When assembling protective shell a2 and protective shell b3, simply insert the elastic rod 6 into the slot. The elastic block 7 will compress and deform as the elastic rod 6 is inserted. When the elastic block 7 reaches the latch 5, it will automatically spring up and snap into the latch 5, thus achieving a tight connection between protective shell a2 and protective shell b3. For disassembly, simply press the elastic block 7 to disengage it from the latch 5, and the elastic rod 6 can be pulled out of the slot, completing the separation of protective shell a2 and protective shell b3.

[0024] The elastic rod 6 can be made of spring steel, with an elastic coefficient generally between 50-100 N / mm. This elastic coefficient ensures that the elastic rod 6 has sufficient elastic deformation capacity during insertion and removal, and also ensures sufficient connection strength between the protective shell a2 and the protective shell b3 in the connected state. The dimensions of the elastic block 7 should match the groove 5. Generally, the width of the elastic block 7 is slightly smaller than the width of the groove 5 by 0.5-1 mm, and the height is slightly smaller than the depth of the groove 5 by 0.2-0.5 mm, to ensure that the elastic block 7 can be smoothly inserted into the groove 5 and will not loosen after connection.

[0025] In some technical solutions, the interactive touch display screen 1 has a processing chip inside, and the processing chip has an input module, an identity recognition module and a monitoring module inside.

[0026] The processing chip is the core computing component of the entire interactive touch display screen 1. It is responsible for coordinating the work of various modules, processing user input information, identifying users, and monitoring the entire interaction process. The input module is mainly responsible for receiving commands input by the user through the touch screen, external devices (such as a keyboard or mouse), etc., and transmitting these commands to the processing chip for processing. The identification module uses various identification technologies, such as facial recognition, ID card recognition, and fingerprint recognition, to verify the user's identity, ensuring that only authorized users can perform related operations. The monitoring module is mainly used to monitor the working status of the interactive touch display screen 1 in real time, including the screen display status, touch response status, device temperature, voltage, and other parameters. If any abnormality is detected, it will promptly issue an alarm or take appropriate measures to handle the situation. The processing chip can utilize a high-performance embedded processor, such as Rockchip's RK3588, which employs an 8-core Cortex-A76 / A55 architecture with a maximum clock speed of 2.4GHz. It possesses powerful computing capabilities, enabling rapid processing of complex images, videos, and user input information. The input module supports multiple input interfaces, such as a USB interface supporting the USB 3.0 protocol with a maximum transmission rate of 5Gbps, allowing for rapid response to input commands from external devices. The facial recognition function in the identity recognition module achieves an accuracy rate of over 99% and a recognition speed of less than 1 second; the ID card recognition module can complete the reading and verification of ID card information within 3-5 seconds; and the fingerprint recognition module achieves an accuracy rate of over 98% and a recognition speed of less than 0.5 seconds. The monitoring module can monitor the device's temperature in real time, typically within a range of 0-80 degrees Celsius. When the temperature exceeds 60 degrees Celsius, it can automatically activate the cooling fan for cooling. It can also monitor the device's voltage with an accuracy of ±0.1V, and can promptly issue alarms when abnormal voltage fluctuations occur.

[0027] Working process and principle: I. Installation Process When installing a hotel digital interactive screen with identity recognition function, the fixing plate b12 is first fixedly connected to the wall, mounting bracket, and other external installation structures through the four mounting holes 13 on its outer wall using bolts, nuts, and other connectors. The reinforced area around the mounting holes 13 and the embedded copper bushing enhance the strength and tightness of the connection, ensuring that the fixing plate b12 is installed securely. Next, protective shells a2 and b3 are fitted onto the left and right ends of the interactive touch display screen 1. The elastic rods 6 at the top and bottom of the side walls of protective shell a2 are aligned with the slots at the top and bottom of the side walls of protective shell b3 and inserted. During insertion, the elastic blocks 7 at the ends of the elastic rods 6 are compressed and deformed. When the elastic blocks 7 reach the snap-fit ​​slots 5 on the top and bottom side walls of protective shell b3, they automatically spring up and snap into the snap-fit ​​slots 5, thus achieving a tight assembly of protective shells a2 and b3 with the interactive touch display screen 1. Simultaneously, the silicone cushioning pad inside the protective shells and the anti-fingerprint and anti-oil coating on the surface also provide protection for the display screen and facilitate future maintenance. Finally, the fixing plate a10 is inserted into the arc-shaped plate groove 8 at the center of the opposite side walls of protective shells a2 and b3, and the fixing rod a11 is set in the arc-shaped rod groove 9, completing the connection between the angle adjustment mechanism 4 and the protective shells and display screen. The entire installation process is simple and convenient. II. Angle Adjustment Process and Principle When a user needs to adjust the angle of the interactive touch display screen 1, the operating principle is based on the special design of the angle adjustment mechanism 4. Rotating the fixed plate a10, which is inserted into the arc-shaped groove 8, and the fixed rod a11 set in the arc-shaped groove 9, causes the fixed rod a11 to move along the arc-shaped groove 9, thus moving the fixed plate a10 along the arc-shaped groove 8 in an arc-shaped trajectory. This allows the screen angle to be adjusted within the range of 0-90 degrees to accommodate users of different heights and different usage scenarios. Meanwhile, the fit between the ball sleeve 17 at the end of the fixed rod a11 and the ball 15 at the end of the fixed rod b14 allows the screen to not only adjust its angle but also rotate in all directions. The ball 15 is fitted within the rotating cavity 16 of the ball sleeve 17, with a clearance fit between the cavity 16 and the ball 15 (the clearance is controlled between 0.1 and 0.3 mm). This design allows the ball 15 to rotate freely within the cavity 16. When the user operates the screen in different positions, this omnidirectional rotation function allows for fine-tuning of the screen's horizontal and vertical directions. During rotation, the grease added to the cavity 16 and the dustproof sealing ring at the opening of the ball sleeve 17 ensure smooth and stable rotation, extending the lifespan of the components. Once the screen is adjusted to the appropriate angle, the ratchet and pawl locking mechanism of the angle adjustment mechanism 4 automatically locks, preventing the screen from rotating accidentally due to external forces. III. Identity Recognition and Interaction Process and Principles After the interactive touchscreen display 1 starts working, the user inputs commands via the touchscreen or external devices (such as a keyboard or mouse). The input module receives these commands using interfaces such as USB 3.0 and transmits them to the processing chip. The processing chip uses a high-performance embedded processor such as the Rockchip RK3588, with an 8-core Cortex-A76 / A55 architecture and a maximum clock speed of 2.4GHz, enabling it to quickly process complex commands. Before performing any operation, the identity recognition module verifies the user's identity. This module integrates multiple technologies such as facial recognition, ID card recognition, and fingerprint recognition. Facial recognition accuracy reaches over 99% with a recognition speed of less than 1 second; ID card recognition can complete information reading and verification within 3-5 seconds; and fingerprint recognition accuracy reaches over 98% with a recognition speed of less than 0.5 seconds. Furthermore, the added liveness detection function effectively prevents the identification of forged identity information. Only authorized users who have been verified can perform subsequent operations, ensuring information security and the standardization of hotel services. Throughout the interaction process, the monitoring module monitors the device status in real time. It can monitor device temperature (range 0-80 degrees Celsius, automatically activating the cooling fan when exceeding 60 degrees Celsius), voltage (monitoring accuracy ±0.1V, with timely alarms for abnormal fluctuations), screen display, touch response, and network connection status. Upon detecting any anomalies, it promptly issues alarms or takes appropriate measures to ensure stable device operation and smooth interaction. Simultaneously, the processing chip's built-in 8GB DDR4 memory and 64GB eMMC storage provide robust support for system operation and data storage. The software of each module can also be regularly updated and optimized to continuously improve system performance and security.
