Description

Technical Field

[0001] This utility model belongs to the field of hotel intelligent technology, specifically a hotel facial recognition device. Background Technology

[0002] Hotel facial recognition devices are intelligent devices that integrate hardware and smart algorithms, adapting to various service and management scenarios in hotels. They are one of the core supporting facilities for smart hotels.

[0003] It uses facial recognition technology as its core, covering the entire process from guest check-in to check-out, while also taking into account the needs of hotel security control and operation management.

[0004] In smart hotels where facial recognition is used to enter rooms, users of different heights are frequently encountered. For children or wheelchair users, due to height limitations, they often need to adjust their posture, such as tiptoeing or straightening their bodies, to ensure their faces are within the recognition range. This greatly reduces the convenience of operation for such users and results in poor compatibility of existing hotel facial recognition devices. Therefore, a hotel facial recognition device is proposed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a hotel facial recognition device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hotel facial recognition device, including a mounting frame, a recognition display, which is slidably disposed on the outside of the mounting frame under external force, two magnet blocks, which are slidably connected to the inside of the mounting frame and magnetically attracted to the inside of the mounting frame, and a connecting rod fixedly disposed on the outside of the magnet blocks. A friction component is fixedly disposed on the side of the recognition display close to the mounting frame, and the connecting rod is slidably disposed on the inside of the recognition display.

[0007] Preferably, the friction assembly includes a slider, the slider is covered with nitrile rubber, and thin magnetic sheets are embedded on both sides of the nitrile rubber. The thin magnetic sheets react magnetically with the iron plate. The iron plates on both sides are symmetrically fixed inside the mounting frame. The inside of the mounting frame is made of a rough silicon carbide ceramic material.

[0008] Preferably, the identification display has a limiting groove on the side near the magnet block, and a connecting rod is symmetrically slidably provided on the inner side of the limiting groove to ensure the relative horizontal sliding of the magnet blocks on both sides.

[0009] Preferably, the magnets on both sides are driven by the connecting rods on both sides to slide horizontally closer or further apart, and the magnets have a magnetic attraction reaction with the iron plate on the corresponding side of the inner wall of the mounting frame.

[0010] Preferably, an infrared detector is fixedly installed on the top inner side of the mounting bracket, an electric push rod is fixedly installed on the bottom inner side of the mounting bracket, and a receiving plate is fixedly installed on the output end of the electric push rod.

[0011] Preferably, the magnets on both sides repel each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a structure combining nitrile rubber, a thin magnetic sheet, and a magnetic block to allow for easy release of the high magnetic attraction with a single hand, enabling the user to slide the recognition display downwards. During this process, the high coefficient of friction between the nitrile rubber and the inner side of the mounting bracket causes the recognition display to slide down slowly. Simultaneously, the low magnetic attraction between the thin magnetic sheet and the iron plate ensures that the recognition display maintains a low-speed downward movement while being manipulated by the user, facilitating support and operation. Once the display reaches the desired position, the high magnetic attraction is restored, preventing displacement even from slight vibrations or impacts, thus ensuring the stability and accuracy of facial recognition.

[0015] 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.

[0016] like Figures 1 to 3 As shown, this utility model provides a hotel face recognition device, including a mounting frame 1, a recognition display 2 driven by an external force and slidably disposed on the outside of the mounting frame 1, two magnet blocks 3, the magnet blocks 3 are slidably connected to the inside of the mounting frame 1 and magnetically attracted to the inside of the mounting frame 1, a connecting rod 31 is fixedly disposed on the outside of the magnet blocks 3, wherein a friction component is fixedly disposed on the side of the recognition display 2 near the mounting frame 1, and the connecting rod 31 is slidably disposed on the inside of the recognition display 2.

[0017] During installation, the device is mounted on the wall next to the hotel room door through the mounting holes on the back of the mounting bracket 1, providing a stable base and frame for the entire device. In actual use, the user can press down on the connecting rods 31 on both sides with one hand, causing them to slide relative to each other. This allows the magnets 3 on both sides inside the mounting bracket 1 to disengage from the magnetic attraction between them. After the magnetic attraction between the magnets 3 and the mounting bracket 1 is released, the recognition display 2 tends to slide downwards under its own weight. The user can then use one hand to hold the connecting rods 31 and slide the recognition display 2 downwards. During this process, the friction component maintains a high friction and low magnetic attraction effect with the inner wall of the mounting bracket 1 while ensuring the vertical sliding of the mounting bracket 1. This allows the user to operate the mounting bracket 1 to slide down slowly until the recognition display 2 reaches a suitable position for user recognition. At this point, the user can release the clamping effect on the connecting rods 31 on both sides and operate the connecting rods 31 to slide and reset, so that the connecting rods 31 and the mounting bracket 1 regain high magnetic attraction, thus fixing the recognition display 2 for recognition. During this process, the user can easily adjust the position of the recognition display 2 by manually moving its height to accommodate the recognition needs of users of different heights.

[0018] like Figure 2 As shown, the friction assembly includes a slider 21, with a nitrile rubber 22 sleeved on the outside of the slider 21. Thin magnetic sheets 23 are embedded on both sides of the nitrile rubber 22. The thin magnetic sheets 23 and the iron plate 11 undergo a magnetic attraction reaction. The two iron plates 11 are symmetrically fixed inside the mounting frame 1. The inside of the mounting frame 1 is made of a rough silicon carbide ceramic material.

[0019] During the downward movement of the recognition display 2, the high coefficient of friction between the nitrile rubber 22 and the rough silicon carbide ceramic on the inner surface of the mounting bracket 1 (the coefficient of friction is stable at 0.45-0.65) slows down the downward movement of the slider 21 and the recognition display 2 itself due to gravity. At the same time, the low magnetic attraction between the thin magnetic sheet 23 and the iron plate 11 keeps the recognition display 2 moving at a low speed when the user controls it to slide down, making it easier for the user to support the operation.

[0020] like Figure 2 As shown, a limiting groove 24 is provided on the side of the identification display 2 near the magnet block 3. A connecting rod 31 is symmetrically slidably provided on the inner side of the limiting groove 24 to ensure the relative horizontal sliding of the magnet blocks 3 on both sides.

[0021] When the user operates the recognition display 2 to slide down, the connecting rods 31 on both sides are held with one hand, allowing them to slide within the limiting groove 24. The limiting groove 24 provides precise guidance for the movement of the connecting rods 31, ensuring that the magnets 3 on both sides can slide relatively close or far apart in the horizontal direction, avoiding deviation or jamming during the movement. At the same time, it ensures that the movement of the magnets 3 on both sides is synchronized, thereby making the force on the recognition display 2 more uniform and the sliding more stable and smooth.

[0022] like Figures 2 to 3 As shown, the two magnet blocks 3 are driven by the two connecting rods 31 to slide horizontally closer or further apart. The magnet blocks 3 and the iron plate 11 on the corresponding side of the inner wall of the mounting frame 1 have a magnetic attraction reaction, and the two magnet blocks 3 repel each other.

[0023] When the recognition display 2 needs to be adjusted, the external force applied by the user mainly needs to overcome the repulsive force between the two magnet blocks 3, so that the two magnet blocks 3 release the magnetic attraction between them and the iron plate 11. When the recognition display 2 slides to a certain position and stops, the external force is released, and the magnet blocks 3 are brought close to the iron plate 11, which will restore the magnetic attraction between them. Thus, the recognition display 2 is firmly locked and fixed in this position by the connecting rod 31 and the limiting slide groove 24. The magnet blocks 3 and the iron plate 11 provide a strong positioning force, which can keep the recognition display 2 firmly in the position set by the user. Even if it is subjected to slight vibration or collision, it is not easy to move, ensuring the stability and accuracy of face recognition. At the same time, a small initial thrust is converted into a large final positioning force through the mechanical structure.

[0024] like Figure 2 As shown, an infrared detector 12 is fixedly installed on the top inner side of the mounting bracket 1, and an electric push rod 13 is fixedly installed on the bottom inner side of the mounting bracket 1. A receiving plate 14 is fixedly installed at the output end of the electric push rod 13.

[0025] After the user slides down to recognize the face on the display 2, after a period of time, the infrared detector 12 detects the positional distance between itself and the slider 21, and sends a signal through the control system to drive the electric push rod 13 to move the receiving plate 14 against the bottom of the two magnet blocks 3, and continue to push upward until the pushing force is greater than the frictional force between the two magnet blocks 3 and the iron plate 11, so that the recognition display 2 returns to its initial position for subsequent use by the user.

[0026] Working principle and usage process of this utility model: In actual use, the user can press the connecting rods 31 on both sides with one hand to make them slide and clamp, thereby causing the magnets 3 on both sides inside the mounting bracket 1 to disengage from the magnetic attraction between them and the inner iron plate 11. After the magnetic attraction between the magnets 3 and the iron plate 11 is released, the recognition display 2 tends to slide downwards under its own weight and the weight of the slider 21. The user can then use one hand to hold the connecting rods 31 to slide the recognition display 2 downwards. During this process, the high coefficient of friction (stable at 0.45-0.65) between the nitrile rubber 22 and the rough silicon carbide ceramic inner surface of the mounting bracket 1 makes the slider... The downward speed of block 21 and recognition display 2 is slowed down by gravity. At the same time, the low magnetic attraction between thin magnetic sheet 23 and iron plate 11 keeps the recognition display 2 sliding at a low speed, which is convenient for the user to support the operation until the recognition display 2 reaches a suitable position for the user to recognize. At this time, the user can release the clamping effect on the two connecting rods 31 and operate the connecting rods 31 to slide and reset, so that the connecting rods 31 and the mounting bracket 1 regain high magnetic attraction, thus fixing the recognition display 2 and enabling recognition. During this process, the user can easily adjust the position by manually moving the height of the recognition display 2 to adapt to the recognition needs of users of different heights.
