Description

Technical Field

[0001] This utility model relates to the field of facial recognition access control scanning screen technology, specifically a waterproof facial recognition access control scanning screen. Background Technology

[0002] With the rapid development of intelligent security technology, facial recognition access control systems have been widely used in various scenarios such as residential communities, office buildings, and industrial parks due to their advantages of convenience and high security. Among them, the facial recognition access control scanning screen, as the core interactive component of the system, is often exposed to outdoor or semi-open spaces and must be exposed to complex external factors such as rain, dust, and temperature changes for a long time. Therefore, high requirements are placed on the waterproof performance, heat dissipation performance, and adaptability of the equipment.

[0003] However, existing facial recognition access control scanning screens still have many shortcomings in practical applications. On the one hand, the waterproof structure design of most products is relatively simple, relying only on basic seals at the gaps in the outer shell for waterproofing. This is insufficient to effectively prevent rain splashes or moisture penetration in humid environments. Once moisture enters the device, it can easily cause short circuits in the scanning screen circuitry and damage to components due to moisture. This not only affects the normal operation of the device but also significantly shortens its lifespan and increases subsequent maintenance costs. On the other hand, some products excessively seal the outer shell to improve waterproofing, which can prevent the timely dissipation of internal heat. Especially in high-temperature environments in summer or under prolonged continuous operation, the internal temperature of the scanning screen continues to rise, easily leading to problems such as slower recognition speed and increased false recognition rates. In severe cases, it can even cause the device to shut down.

[0004] On the other hand, the installation height and tilt angle of existing facial recognition access control scanning screens are mostly fixed, or can only be adjusted to a limited extent through complex disassembly and adjustment structures. Because users' heights vary greatly in different scenarios (e.g., adults and children, ordinary people and people of special heights), and the spatial layout and lighting angles of the installation locations differ, fixed structural designs cannot meet diverse usage needs. For example, an installation height that is too high may prevent children or shorter individuals from completing facial recognition properly, while an improper angle may affect the scanning screen's recognition accuracy due to light reflection, reducing the system's ease of use and user experience.

[0005] In addition, some products with adjustment functions have insufficient stability of the adjustment mechanism, which is prone to self-displacement after adjustment, requiring frequent recalibration, further increasing the inconvenience of use. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a waterproof face recognition access control scanning screen. This screen offers the advantages of synergistic improvement in waterproofing and heat dissipation performance, while also enabling flexible and stable adjustment of the device's height and angle. This solves the problems in existing face recognition access control scanning screens where insufficient waterproofing often leads to moisture damage to internal components, or where poor heat dissipation affects the device's operational stability and lifespan.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof facial recognition access control scanning screen, comprising a base, a hollow column fixedly connected to the top of the base, a slider slidably connected inside the hollow column, a sliding column fixedly connected to the top of the slider, and the sliding column slidably connected to the hollow column, a connecting block fixedly connected to the top of the sliding column, an insertion block mounted on the surface of the connecting block, a hinge fixedly connected to the other end of the insertion block, a rotating member rotatably connected inside the hinge, a protective shell fixedly connected to the other end of the rotating member, an installation groove provided on the surface of the protective shell, a facial recognition access control scanning screen body installed inside the installation groove, a sealing sleeve fixedly connected inside the installation groove, and the sealing sleeve cooperates with the facial recognition access control scanning screen body, partition strips symmetrically fixedly connected inside the installation groove, a plurality of vertically evenly arranged inclined openings provided on the surface of the partition strips, and a plurality of vertically evenly arranged heat dissipation holes provided on the surface of the protective shell, with the heat dissipation holes all located below the plurality of inclined openings.

[0008] As a preferred embodiment of this utility model, the protective shell has symmetrically provided filter grooves on its back side, and both filter grooves are located between the inclined opening and the heat dissipation hole. A filter frame is snapped into the inside of the filter groove, and a breathable waterproof membrane and a filter screen are respectively installed inside the two filter frames, with the breathable waterproof membrane located above the filter screen.

[0009] In a preferred embodiment of this invention, a damping sleeve is fitted onto the surface of the slider, and the damping sleeve is slidably connected to the hollow column. A damping ring is fixedly connected to the inner wall of the hollow column, and the damping ring is slidably connected to the slider.

[0010] As a preferred embodiment of this invention, the surface of the rotating component is fixedly connected with a plurality of uniformly arranged ring-shaped snap-fit ​​strips, and the inner side of the hinge component is fixedly connected with a rubber strip, which is used in conjunction with the snap-fit ​​strips.

[0011] As a preferred embodiment of this invention, the top and bottom of the rotating component are both fixedly connected with reinforcing strips, and the other end of the reinforcing strips is fixedly connected to the protective shell.

[0012] As a preferred embodiment of this utility model, the bottom of the mounting groove is provided with symmetrical drainage outlets on both sides, and the two drainage outlets are respectively located on the outer side of the two partition strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a sealing sleeve in the mounting groove of the protective shell and using the sealing sleeve in conjunction with the main body of the face recognition access control scanning screen, can effectively fill the gap between the main body of the face recognition access control scanning screen and the wall of the mounting groove, preventing external moisture and dust from entering the interior of the mounting groove. At the same time, the surface of the partition strip symmetrically arranged in the mounting groove has vertically evenly arranged inclined openings, and the surface of the protective shell has vertically evenly arranged heat dissipation holes below the inclined openings. The inclined openings and heat dissipation holes form a complete heat dissipation airflow channel, which can promptly dissipate the heat generated by the main body of the face recognition access control scanning screen during operation.

A connecting block is connected to the top of the sliding post. A damping sleeve, also slidingly connected to the hollow column, is fitted onto the surface of the slider. A damping ring, also slidingly connected to the sliding post, is fixedly connected to the inner wall of the hollow column. The damping sleeve and ring work together to provide stable damping force to the sliding post, allowing it to stop at any height and facilitating adjustment of the height of the face recognition access control scanning screen. Furthermore, the connecting block connects to a hinge via a plug-in block. A rotating component is rotatably connected within the hinge. The rotating component has evenly arranged ring-shaped locking strips on its surface, and a rubber strip mates with these locking strips on the inner side of the hinge. This allows for flexible adjustment of the tilt angle of the protective shell and the face recognition access control scanning screen. Compared to existing face recognition access control scanning screens with inconvenient height and angle adjustments and poor adaptability, this utility model better adapts to users of different heights and different installation environments, improving flexibility and adaptability.

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 4As shown, this utility model provides a waterproof facial recognition access control scanning screen, including a base 1. A hollow column 2 is fixedly connected to the top of the base 1. A slider 3 is slidably connected inside the hollow column 2. A sliding column 4 is fixedly connected to the top of the slider 3, and the sliding column 4 is slidably connected to the hollow column 2. By sliding the slider 3 inside the hollow column 2 in conjunction with the synchronous movement of the sliding column 4, the height of the sliding column 4 can be flexibly adjusted to adapt to the height requirements of the device in different scenarios. A connecting block 5 is fixedly connected to the top of the sliding column 4, and the surface of the connecting block 5... A connector 6 is installed, with a hinge 7 fixedly connected to the other end of the connector 6. The assembly of the connector 5 and the connector 6 provides a stable mounting base for the hinge 7, facilitating subsequent disassembly and maintenance of the hinge 7 and related components. A rotating component 8 is rotatably connected inside the hinge 7, with a protective shell 9 fixedly connected to the other end of the rotating component 8. The rotational cooperation between the hinge 7 and the rotating component 8 allows the protective shell 9 to rotate at an angle, facilitating adjustment of its tilt direction. An installation groove is provided on the surface of the protective shell 9. The device houses the main body 10 of a facial recognition access control scanning screen. The mounting slot provides a dedicated installation space for the main body 10, ensuring its stability after installation. A sealing sleeve 11 is fixedly connected inside the mounting slot, working in conjunction with the main body 10 to fill the gap between the main body 10 and the mounting slot wall, effectively preventing external moisture and dust from entering the mounting slot. A partition strip 12 is symmetrically fixedly connected inside the mounting slot. The surface of the partition strip 12 has several vertically evenly arranged inclined openings 13. The partition strip 12 divides the space within the mounting slot, while the inclined openings 13 guide airflow, providing a channel for heat dissipation. The protective shell 9 has several vertically evenly arranged heat dissipation holes 14 on its surface, all located below the inclined openings 13. The vertical alignment of the inclined openings 13 and the heat dissipation holes 14 forms a complete heat dissipation airflow channel, effectively dissipating the heat generated by the main body 10 during operation.

[0023] refer to Figure 4 The protective shell 9 has symmetrically opened filter grooves on the back, and both filter grooves are located between the inclined opening 13 and the heat dissipation hole 14. The filter grooves are fitted with filter frames 15. The two filter frames 15 are respectively installed with a breathable and waterproof membrane 16 and a filter screen 17, and the breathable and waterproof membrane 16 is located above the filter screen 17.

[0024] As a technical optimization of this utility model, the filter frame 15 is provided with an installation position through the filter groove, and the snap-fit ​​structure facilitates the disassembly and replacement of the filter frame 15; the breathable and waterproof membrane 16 can prevent external moisture from entering the protective shell 9 through the filter groove while ensuring normal air circulation; the filter screen 17 can intercept dust and impurities in the air, avoid dust accumulation and block the heat dissipation channel, and ensure the long-term stable operation of the heat dissipation system.

[0025] refer to Figure 3 The surface of the slider 3 is fitted with a damping sleeve 18, and the damping sleeve 18 is slidably connected to the hollow column 2. The inner wall of the hollow column 2 is fixedly connected with a damping ring 19, and the damping ring 19 is slidably connected to the slider 4.

[0026] As a technical optimization of this utility model, the damping sleeve 18 increases the friction between the slider 3 and the inner wall of the hollow column 2, and the damping ring 19 enhances the contact resistance between the slider 4 and the hollow column 2. The two work together to provide stable damping force for the sliding of the slider 4, so that the slider 4 can stay at any height position and the height can be locked without additional fixing structure, thus improving the convenience of equipment height adjustment.

[0027] refer to Figure 3 The surface of the rotating part 8 is fixedly connected with multiple ring-shaped and uniformly arranged snap-fit ​​strips 20, and the inner side of the hinge part 7 is fixedly connected with a rubber strip 21, and the rubber strip 21 is used in conjunction with the snap-fit ​​strips 20.

[0028] As a technical optimization of this utility model, the ring-arranged snap-fit ​​strips 20 can provide multiple angle adjustment options. The rubber strip 21 has a certain elasticity. When the rotating part 8 rotates, the rubber strip 21 can be tightly engaged with the snap-fit ​​strips 20 at different positions to fix the rotation angle of the rotating part 8, thereby accurately locking the tilt angle of the protective shell 9 and the main body 10 of the face recognition access control scanning screen.

[0029] refer to Figure 2 The top and bottom of the rotating part 8 are fixedly connected with reinforcing strips 22, and the other end of the reinforcing strips 22 is fixedly connected to the protective shell 9. The reinforcing strips 22 are made of rigid material.

[0030] As a technical optimization of this utility model, the reinforcing strip 22 is made of rigid material and is fixed to the rotating part 8 and the protective shell 9 at both ends to form a triangular support structure, which enhances the connection strength between the rotating part 8 and the protective shell 9, avoids loosening and deformation of the connection between the two due to long-term use or external impact, and extends the overall service life of the equipment.

[0031] refer to Figure 1 and Figure 4The bottom of the installation groove is symmetrically provided with two drain outlets 23, and the two drain outlets 23 are located on the outside of the two partition strips 12 respectively. Insect-proof nets are installed inside the drain outlets 23.

[0032] As a technical optimization of this utility model, the drain outlet 23 can promptly drain any small amount of water that may accidentally seep into the installation groove, preventing water accumulation from corroding the main body 10 of the face recognition access control scanning screen. At the same time, the insect net can block mosquitoes and small particles from entering the installation groove through the drain outlet 23, preventing mosquitoes from nesting in the installation groove or preventing impurities from accumulating and affecting the normal operation of the equipment.

[0033] The working principle and usage process of this utility model are as follows: When using this waterproof face recognition access control scanning screen, first place the base 1 in the designated installation position to ensure the overall stability of the device. Then, adjust the height of the device according to the user's height requirements in the usage scenario. Specifically, push the connecting block 5 to drive the sliding column 4 and slider 3 to slide inside the hollow column 2. The damping sleeve 18 on the surface of the slider 3 slides in cooperation with the inner wall of the hollow column 2, and the damping ring 19 on the inner wall of the hollow column 2 slides in cooperation with the sliding column 4. The damping force provided by both allows the sliding column 4 to stop at any suitable height, thereby completing the height adjustment of the face recognition access control scanning screen body 10; subsequently, according to... Adjust the device's tilt angle according to the user's standing angle or ambient lighting conditions. By rotating the protective shell 9, the rotating component 8 rotates inside the hinge 7. The evenly arranged ring-shaped locking strips 20 on the surface of the rotating component 8 rotate synchronously with it. When the appropriate angle is reached, the rubber strip 21 on the inner side of the hinge 7 engages with the corresponding locking strip 20, fixing the angle of the rotating component 8 and the protective shell 9. At the same time, the reinforcing strips 22 at the top and bottom of the rotating component 8 ensure the stability of the connection between the rotating component 8 and the protective shell 9, preventing the connection from loosening when adjusting the angle. After adjustment, the user can use facial recognition within the mounting slot of the protective shell 9. The access control scanning screen body 10 performs facial recognition. The sealing sleeve 11 in the mounting slot fills the gap between the facial recognition access control scanning screen body 10 and the mounting slot wall to prevent external moisture and dust from entering the mounting slot. During the operation of the facial recognition access control scanning screen body 10, the heat generated by it enters the heat dissipation channel through the inclined opening 13 on the surface of the partition strip 12 in the mounting slot, and is then discharged through the heat dissipation holes 14 on the surface of the protective shell 9. At the same time, the filter frame 15 in the filter groove on the back of the protective shell 9 plays a role. The breathable and waterproof membrane 16 inside the filter frame 15 ensures air circulation while blocking external moisture from entering the protective shell 9, and the filter screen 17 intercepts airborne particles. Dust and impurities are removed to prevent dust from clogging the heat dissipation channels. If a small amount of moisture accidentally seeps into the mounting groove, it will be discharged through the drain outlets 23 located on both sides of the bottom of the mounting groove outside the partition strip 12. The insect screen inside the drain outlet 23 prevents mosquitoes and small particles from entering the mounting groove through the drain outlet 23. When maintenance of the filter structure is required, the filter frame 15 can be removed from the filter groove on the back of the protective shell 9 for cleaning or replacement and then reattached to the filter groove. If maintenance of other parts of the equipment is required, the hinge 7 and related parts can be separated from the connecting block 5 by disassembling the plug block 6 on the surface of the connecting block 5 for subsequent maintenance operations.
