Description
Technical Field
[0001] This utility model relates to the field of facial payment device technology, and in particular to a facial payment device with anti-polarization function. Background Technology
[0002] With the rapid development of mobile payment technology, facial payment devices with anti-polarization technology have been widely used in retail, transportation, finance, and other fields due to their convenience and security. These devices capture user facial images through a camera and combine anti-polarization technology to reduce ambient light interference, enabling accurate facial recognition payment. However, in practical use, the long-term stable operation of these devices faces many challenges, especially the protection and maintenance of the camera and its anti-polarization components, which have become key factors affecting device performance and lifespan.
[0003] Existing facial payment devices typically employ a fixed design for their camera's anti-polarization structure. This usually involves directly attaching the polarizing film to the camera surface or integrating it into the device's casing, using optical coatings and sealing structures to reduce ambient light reflection. The connection between the device and its bracket is often achieved through screws or welding to ensure stability during use. While this design provides a degree of anti-polarization performance and structural stability, it lacks a flexible maintenance and disassembly mechanism in practical applications.
[0004] However, the aforementioned existing technologies have significant drawbacks. Due to the fixed design of the camera's anti-polarization structure, it is difficult to clean and replace the polarizing film when it becomes contaminated with dust or oil, or when it ages or scratches due to long-term use. Furthermore, the integrated structure often requires disassembling the entire device from the bracket for camera maintenance, a cumbersome and time-consuming process. This not only reduces maintenance efficiency but also leads to device damage due to frequent disassembly, further affecting the reliability of the anti-polarization performance and the device's adaptability to complex environments. Therefore, a facial payment device with anti-polarization functionality is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a facial payment device with anti-polarization function, which aims to improve the problems of easy contamination of cameras, difficult maintenance of aging polarization films, and interference with imaging by ambient light in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A facial payment device with anti-polarization function includes a base, a payment screen on the top of the base, a protective component on the top of the payment screen, and a disassembly component on the top of the base;
[0008] The protective assembly includes a protective cover and anti-polarization glass. The outer wall of the protective cover is slidably connected to the outer wall of the payment screen, and the outer wall of the anti-polarization glass is fixedly connected to the inside of the protective cover. A limiting groove is provided inside the protective cover, and a friction plate is slidably connected inside the protective cover. The friction plate is in contact with the payment screen, and a limiting plate is fixedly connected to one side of the friction plate. The outer wall of the limiting plate is slidably connected to the limiting groove. A spring is provided inside the protective cover.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the friction plate moves by pulling the protective cover. When the protective cover is pulled, the friction plate and the limiting plate are driven by the protective cover and cooperate with the spring to slide the friction plate inside the protective cover, thereby conveniently protecting the payment screen camera. This solves the problems of camera being easily contaminated, polarizing film aging and difficult maintenance, and ambient light interference with imaging, and improves equipment maintenance efficiency, anti-polarization performance reliability and environmental adaptability.

[0033] 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.
[0034] Reference Figures 1-3 An embodiment of this utility model provides a facial payment device with anti-polarization function, including a base 1. The base 1 is made of high-strength aluminum alloy, precision die-cast, and anodized. It has good wear resistance and corrosion resistance, and is used to provide stable support for the entire device, ensuring that the device will not tip over due to slight collisions or shaking during use. For example, it can be placed stably in places with high traffic such as shopping mall cashiers. A payment screen 3 is provided on the top of the base 1, a protective component is provided on the top of the payment screen 3, and a disassembly component is provided on the top of the base 1.
[0035] The protective components include a protective cover 2 and an anti-polarization glass 4. The outer wall of the protective cover 2 is slidably connected to the outer wall of the payment screen 3. The protective cover 2 is made of optical-grade polycarbonate (PC), which has high light transmittance and impact resistance. Its outer wall is slidably connected to the outer wall of the payment screen 3 via a precision-designed slide rail. This slide rail structure allows the protective cover 2 to slide smoothly up and down along the payment screen 3, achieving a convenient opening and closing effect. The outer wall of the anti-polarization glass 4 is fixedly connected to the inside of the protective cover 2 using optical-grade adhesive. The anti-polarization glass 4 uses multiple... The layer coating technology can effectively filter polarized light in the environment and reduce reflection and glare. For example, in outdoor scenes with direct sunlight, it can make the camera image of the payment screen 3 clearer. The protective cover 2 has a limiting groove 7 inside, and a friction plate 5 is slidably connected inside the protective cover 2. The friction plate 5 is in contact with the payment screen 3. A limiting plate 8 is fixedly connected to one side of the friction plate 5. The outer wall of the limiting plate 8 is slidably connected inside the limiting groove 7. A spring 6 is set inside the protective cover 2. One end of the spring 6 is fixedly connected to the outer wall of the limiting plate 8, and the other end of the spring 6 is fixedly connected to the inner wall of the limiting groove 7.
[0036] Specifically, when using the payment screen 3, the operator only needs to hold the protective cover 2 with one hand and slide it upwards along the outer wall of the payment screen 3. During the movement of the protective cover 2, the friction generated by the close contact between its inner wall and the friction plate 5 will drive the friction plate 5 to move synchronously. The limiting plate 8 connected behind the friction plate 5 will slide smoothly in the limiting groove 7. During this process, the spring 6 is gradually compressed and stores elastic potential energy. When the protective cover 2 moves to a specific position, the anti-polarization glass 4 just covers the camera of the payment screen 3. At this time, the protective cover 2 is released, and the compressed spring 6 quickly rebounds, pushing the friction plate 5 to press against the inner wall of the payment screen 3. By using friction and the rebound force of the spring, the protective cover 2 is firmly fixed. The anti-polarization glass 4, with its special optical structure, effectively filters polarized light in the environment. It can not only prevent external dust, liquid and other contaminants from contacting the camera, but also significantly improve the imaging quality of the camera in strong light and complex light source environments, and comprehensively protect the normal use and payment security of the payment screen 3.
[0037] Reference Figure 1 , Figure 4 and Figure 5 The assembly includes a connecting plate 11 and a connecting housing 10. The outer wall of the connecting plate 11 is slidably connected to the inside of the connecting housing 10. The connecting plate 11 is made of high-strength carbon steel and is formed by CNC cutting and bending. Its outer wall is slidably connected to the inside of the connecting housing 10 through a precision-machined dovetail groove. This dovetail groove structure can effectively limit the movement direction of the connecting plate 11 and ensure that it will not shift during sliding. This is used to realize the detachable connection between the payment screen 3 and the base 1, which is convenient for future maintenance and replacement of the payment screen 3. The bottom of the connecting plate 11 is fixedly connected to the top of the base 1, and the outer wall of the connecting housing 10 is fixedly connected to the outer wall of the payment screen 3. The connecting plate 11 has a moving groove 18 inside. A turntable 15 is rotatably connected inside the connecting plate 11. A limiting groove 16 is opened inside the turntable 15. A knob 9 is fixedly connected to the outer wall of the turntable 15. The surface of the knob 9 is provided with anti-slip texture for easy gripping and rotation by the operator. A locking post 12 is slidably connected inside the connecting plate 11. The outer wall of the locking post 12 is slidably connected to the inside of the outer shell 10. A sliding post 17 is fixedly connected to one end of the locking post 12. The outer wall of the sliding post 17 is slidably connected inside the limiting groove 16. A limiting ring 13 is fixedly connected to the outer wall of the locking post 12. The outer wall of the limiting ring 13 is slidably connected inside the moving groove 18. A second spring 14 is sleeved on the outer wall of the locking post 12. One end of the second spring 14 is fixedly connected to the inner wall of the moving groove 18, and the other end of the second spring 14 is fixedly connected to the outer wall of the limiting ring 13.
[0038] Specifically, when the payment screen 3 malfunctions or requires routine maintenance, technicians do not need to use complex tools such as screwdrivers. They only need to hold the knob 9 by hand and gently turn it clockwise. The knob 9 is tightly connected to the turntable 15, and the turntable 15 rotates synchronously as the knob 9 rotates. The limiting groove 16 inside the turntable 15 rotates accordingly. The special contour design of the limiting groove 16 can accurately guide the sliding column 17 to move inside it. The sliding column 17 is fixedly connected to the locking column 12, thereby driving the locking column 12 to slide inside the connecting housing 10 until the locking column 12 slides completely out of the connecting housing 10, releasing the lock on the payment screen 3. At this time, the payment screen 3 can be easily removed. During the movement of the locking column 12, the limiting ring 13 connected to it moves synchronously, compressing the spring 14 and storing its elastic potential energy. After maintenance is completed, align the payment screen 3 with the installation position, release the knob 9, and the spring 14 will quickly release its elastic potential energy and rebound, pushing the locking pin 12 back into the connecting housing 10, thus quickly fixing the payment screen 3. The whole process is simple and efficient, greatly shortening the equipment maintenance time.
[0039] Working principle: When using the payment screen 3, the protective cover 2 can be slid to the top of the payment screen 3. The movement of the protective cover 2 moves the friction plate 5, and then the friction plate 5 drives the limiting plate 8 to slide inside the limiting groove 7, compressing the spring 6. After the anti-polarization glass 4 covers the camera of the payment screen 3, the spring 6 rebounds and drives the friction plate 5 to contact the inner wall of the payment screen 3, thereby fixing the protective cover 2. Thus, the anti-polarization glass 4 protects the camera of the payment screen 3 from polarization.
[0040] Additionally, when maintenance is required on the payment screen 3, the knob 9 can be rotated, which in turn rotates the turntable 15. The turntable 15 then rotates the internal limiting groove 16, which in turn moves the internal sliding column 17. The sliding column 17 then moves the locking column 12, causing it to slide out of the connecting housing 10, thus removing the payment screen 3. Simultaneously, as the locking column 12 moves, it moves the limiting ring 13, compressing the second spring 14. After maintenance, the screen is returned to its original position, the knob 9 is released, and the spring 14 rebounds, causing the locking column 12 to slide back into the connecting housing 10 for a secure connection.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
