Description

Technical Field

[0001] The utility model relates to the technical field of palm brushing, and specifically, to a palm brushing device with reflection light filling. Background Art

[0002] As a new biometric technology, the palm brushing device has broad application prospects. Its application fields include but are not limited to the following aspects:

[0003] Access control system: In places such as office buildings, residential communities, and parks, the palm brushing device can be used in the access control system to conduct efficient and secure identity verification and management of people entering and leaving. Through palmprint and palmar vein recognition technologies, it ensures that only authorized personnel can enter and leave specific areas.

[0004] Mobile payment: Palm brushing payment is the application of the palm brushing device in the payment field.

This payment method eliminates the need to carry a mobile phone or wallet, improving the convenience and security of payment.

[0005] Smart campus: On campus, the palm brushing device can be used for identity verification and attendance management of students, teachers, and logistics staff. By brushing the palm, the identity of people entering and leaving the campus can be verified, and attendance information can be accurately recorded.

[0006] Digital healthcare: Inside the hospital, the palm brushing device can be used in scenarios such as key drug management, doctor and nurse on-duty attendance, etc. In addition, it can also be used for patient identity verification and medical record management, as well as registration and payment, improving the efficiency and security of medical services.

[0007] New retail: In retail places such as shopping malls or supermarkets, customers can use the palm brushing device for membership registration and consumption payment to enjoy a more convenient shopping experience.

[0008] Smart city: In the construction of a smart city, the palm brushing device can provide more efficient and secure access management for public facilities such as libraries and stadiums. At the same time, it can also be used in scenarios such as the city's all-in-one service and bus payment system to enhance the intelligent level of urban management.

[0009] In practical applications, the palm brushing device usually combines visible light filling and infrared light filling technologies to ensure high-quality palmprint and palmar vein images can be obtained under various light conditions. At the same time, the palm brushing device is also equipped with advanced image processing algorithms and recognition algorithms, which can quickly and accurately analyze and process the collected images, thereby achieving efficient and secure identity verification and payment operations.

[0010] During the recognition process of the palm brushing device, in order to improve the accuracy and stability of recognition, light filling technology is usually adopted. The light filling technology mainly includes two types: visible light filling and infrared light filling.

[0011] Visible light supplementary lighting: The palm is supplemented with light through a visible light source, making features such as palm prints and palm veins more clearly visible. This supplementary lighting method is suitable for scenarios with relatively dim light or a relatively dark palm color.

[0012] Infrared supplementary lighting: The palm is supplemented with light using an infrared light source. Since infrared light can penetrate the skin surface, internal features such as palm veins can be captured more accurately. Infrared supplementary lighting technology is of great significance for improving the accuracy and stability of identification.

[0013] To obtain a clear palm image, a uniform supplementary lighting effect is often required. In the prior art, a light guide ring is often used for light homogenization. However, when a palm-sweeping device is provided with components such as a display screen, due to connections and the like, the light guide ring cannot perform supplementary lighting evenly.

[0053] A palm-sweeping device with reflective supplementary lighting provided by an embodiment of the present utility model aims to solve the problems existing in the prior art.

[0054] The technical solution of the present utility model and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present utility model will be described below in conjunction with the drawings.

[0055] The present utility model uses a reflector to reflect the light of the supplementary light lamp to the light guide ring, and emits it evenly through the light-emitting surface, bypasses the connecting components, and has the best light homogenization effect through the light of the same direction in all directions, which is beneficial to obtaining a clearer palm image.

[0056] Figure 1 It is a schematic structural diagram of a palm-sweeping device with reflective supplementary lighting in an embodiment of the present utility model. As Figure 1 shown, a palm-sweeping device with reflective supplementary lighting in an embodiment of the present utility model includes:

[0057] A display screen 1, including a body 8 and a protruding connecting component 4.

[0058] Specifically, the main body is the main part of the display screen, responsible for displaying images, information, or the interface for guiding user operations. In the palm-sweeping device, the display screen is used to display information such as the user's palm-sweeping status, recognition results, or system prompts. In some embodiments, sensors are also provided inside or below the display screen for collecting palm signals. The protruding connecting components are used to support or fix the display screen and can be used to connect the display screen to other components for communication, etc. The protruding design helps to enhance the structural stability and also provides hardware support for the control of the display screen.

[0059] The light guide ring 2 includes a light-emitting surface 10, which is located outside the display screen 1 and surrounds the display screen 1 for guiding light to the light-emitting surface 10 for uniform emission.

[0060] Specifically, the light-emitting surface is the surface of the light guide ring, which is specially designed to scatter light evenly. This surface directly faces the user's palm to ensure that during the palm-sweeping process, the palm is evenly and softly illuminated, reducing shadows and reflections and improving the image quality. Inside the light guide ring, a series of reflecting surfaces or optical fibers are included for efficiently guiding the light emitted by the supplementary light source to the light-emitting surface and achieving uniform distribution of light through a complex structure. In this way, even if the position of the supplementary light source is not directly aligned with the palm, sufficient illumination of the palm can be ensured.

[0061] The supplementary light source 3 is used to emit light.

[0062] Specifically, the supplementary light source is a light source responsible for generating light with sufficient brightness for the light guide ring to guide. In the palm-sweeping device, the brightness and color temperature of the supplementary light source need to be carefully adjusted to ensure that sufficient illumination can be provided without causing glare or interference. Preferably, the supplementary light source is an efficient and energy-saving light source such as an LED (light-emitting diode), which has the advantages of long lifespan, low energy consumption, and fast response.

[0063] The reflector 5 is located on the opposite side of the supplementary light source 3 for reflecting the light of the supplementary light source 3 to the light guide ring 2.

[0064] Specifically, as Figure 2 shown, the reflector is located on the opposite side of the supplementary light source. Its function is to reflect the light emitted by the supplementary light source to the light guide ring, thereby changing the light path so that the light path bypasses the connecting component for emission while the structure of the palm-sweeping device is relatively small. The reflector is usually made of a material with a high reflectivity, such as a mirror aluminum plate or a specially treated plastic plate. Its surface is specially treated to improve the reflection efficiency and reduce light scattering. The structure of the reflector also needs to be designed according to the size of the palm-sweeping device to ensure that the light can be reflected to the light guide ring along the predetermined path.

[0065] Figure 3 This is a schematic structural diagram of another palm-sweeping device with reflective light supplementation in the embodiment of the present invention. As Figure 3As shown, compared with the foregoing embodiments, the reflector in another palm-sweeping device with reflection and supplementary lighting in the embodiments of the present utility model includes:

[0066] The first reflector 6, which is used to receive the light from the supplementary light and reflect it.

[0067] Specifically, the main function of the first reflector is to receive the light emitted by the supplementary light and reflect it in a predetermined direction. In this embodiment, the first reflector reflects the light to the second reflector, and then the second reflector guides the light to the light guide ring. The first reflector is usually made of materials with high reflectivity, such as mirror aluminum plates, silver-plated glass, or specially treated plastics, etc. These materials can effectively reflect light, reduce light absorption and scattering, thereby improving the utilization rate of light. Its surface is specially treated, such as polishing, coating, etc., to further improve the reflection efficiency and uniformity.

[0068] The second reflector 7, which is used to receive the light from the first reflector and reflect it to the light guide ring.

[0069] Specifically, the second reflector receives the light from the first reflector and reflects it again, and finally guides the light to the light guide ring. The second reflector makes the optical path design more flexible and also provides more choices for the position of the supplementary light. The second reflector can be a single plate or composed of more different plates. Such as the third reflector, the fourth reflector, etc. The situation of more reflectors will not be described in this embodiment, but those skilled in the art can understand that this embodiment includes more situations of reflectors. Similar to the first reflector, the second reflector is also made of materials with high reflectivity to ensure the effective reflection of light. The design key points of the second reflector are the same as those of the first reflector, and will not be elaborated here.

[0070] In summary, the first reflector and the second reflector play a crucial role in the palm-sweeping device. Through their efficient reflection, they guide the light emitted by the supplementary light to the light guide ring, making the optical path more flexible and the position of the supplementary light more flexible, providing uniform and sufficient lighting for the palm, thereby improving the accuracy of palm-sweeping recognition and the user experience.

[0071] In some embodiments, the connecting component protrudes in a direction parallel to the surface of the display screen. The connecting component does not protrude perpendicular to the surface of the display screen, but protrudes outward in a direction parallel to the surface of the display screen. This means that the connecting component extends on the same horizontal plane as the edge part of the display screen, but does not increase the thickness of the device in the vertical direction. The protruding connecting component can, to a certain extent, protect the display screen from direct external impacts or scratches, especially when the device is accidentally dropped or collided. Through the tight connection with the peripheral structure, the protruding connecting component helps to enhance the structural stability of the entire device and reduce the deformation caused by vibration or external forces.

[0072] In some embodiments, the light guide ring is connected to the body. The light guide ring may be directly fixed to the edge of the display body or a specific position of the device by screws, snap fasteners or other fasteners. This connection method is simple and direct, which can ensure a tight fit between the light guide ring and the display body, reduce light leakage, and improve aesthetics. In some embodiments, the light guide ring may be indirectly connected to the display body or the device housing through brackets, frames or other intermediate structures. This connection method provides more flexibility and adjustment space, and the position and angle of the light guide ring can be adjusted according to actual needs.

[0073] In some embodiments, the light guide ring includes a groove, and the groove is connected to the connecting component. As Figure 4 and Figure 5 shown, the design of the groove can increase the contact area between the light guide ring and the connecting component, thereby improving the connection stability. This stable connection helps to prevent the light guide ring from loosening or falling off during use, ensuring the overall structure of the device is stable and reliable. The cooperation between the groove and the connecting component can achieve precise positioning of the light guide ring. During the assembly process, the connecting component can be easily inserted into the groove and tightly connected to the light guide ring through appropriate fixing methods (such as screws, snap fasteners, etc.). This design helps to ensure that the position and angle of the light guide ring are accurate, thus ensuring uniform light distribution and effective lighting. The groove in this embodiment is also conducive to utilizing the space above the connecting component, enabling the light path to pass through above the connecting component, improving space utilization rate, and facilitating the miniaturization of the device.

[0074] In some embodiments, the diameter of the body is not greater than 50 cm, and the cross-sectional end point of the light-emitting surface is not the highest point of the light-emitting surface. As Figure 1 and Figure 2 shown, when the diameter of the body is not greater than 50 cm, the palm brushing device is small in size. Designing the light-emitting surface as a curved surface protruding upward can enable the palm to be well illuminated at both relatively close and relatively far distances, thereby obtaining a relatively uniform palm image. In this embodiment, when the body is circular, the diameter of the circle is the diameter of the body. When the body is not circular, the diameter refers to the equivalent diameter of the area of the body. For example, when the body is square with an area of a, the diameter of the circle with an area of a is the equivalent diameter, which is the diameter of the square. The diameter in subsequent embodiments is the same as that in this embodiment and will not be elaborated in the subsequent part.

[0075] In some embodiments, the diameter of the body is not less than 50 cm, and at least one end point of the cross-section of the light-emitting surface is the highest point or the lowest point of the light-emitting surface. As Figure 4 and Figure 5As shown, when the diameter of the body is not less than 50 cm, the shape of the light-emitting surface can be set according to the specific size of the palm-sweeping device, but at least one end point is the highest or lowest point of the light-emitting surface. When one end point is the highest point, usually the highest point is the outer end point to ensure that the light converges inward to illuminate the palm. When one end point is the lowest point, usually the lowest point is the inner end point to ensure that the light converges inward to illuminate the palm.

[0076] In some embodiments, the diameter of the body is not less than 70 cm, and one end point of the cross-section of the light-emitting surface is the highest point of the light-emitting surface. As Figure 4 and Figure 5 shown, when the diameter of the body is not less than 70 cm, the size of the palm-sweeping device is relatively large, and the design of the light-emitting surface can be more flexible. In this embodiment, the outer end point of the light-emitting surface is the highest point, so that the light has a strong converging effect in the middle of the palm, thereby making the image in the middle of the palm clearer.

[0077] In some embodiments, the light guide ring includes at least one total reflection surface for reflecting light to the light-emitting surface. The total reflection surface can efficiently reflect light to the light-emitting surface of the light guide ring, ensuring that the light is fully utilized and distributed inside the light guide ring. This reflection effect can reduce light loss and improve light utilization efficiency. Through a carefully designed total reflection surface, it can be ensured that after the light undergoes multiple reflections inside the light guide ring, it is scattered onto the light-emitting surface in a uniform manner. In this way, when the palm sweeps across, uniform and sufficient illumination can be obtained, thereby improving the accuracy of palm-sweeping recognition and the user experience. The total reflection surface is usually made of materials with high reflectivity, such as mirror aluminum plates, silver-plated glass, or specially treated plastics, etc. These materials can effectively reflect light and reduce light absorption and scattering. The structural design of the total reflection surface needs to consider factors such as the incident angle, reflection angle, and number of reflections of the light. Through a reasonable structural design, it can be ensured that the light reflects inside the light guide ring along a predetermined path and is finally scattered onto the light-emitting surface in a uniform manner.

[0078] In some embodiments, the thickness of the connecting component is a fixed value. When the thickness of the connecting component is a fixed value, it means that during the entire design or manufacturing process, the thickness dimension of this component remains unchanged and does not change with the variation of other factors (such as position, force conditions, etc.). A connecting component with a fixed thickness is easier to control the dimensions and accuracy during the manufacturing process, thus simplifying the production process. This helps to reduce the manufacturing cost and improve the production efficiency. Since the thickness of the connecting component is fixed, the structural consistency of each component can be ensured. This helps to maintain the stability and reliability of the overall performance of the device. A connecting component with a fixed thickness is more convenient for installation and maintenance. Because they have uniform dimensions and specifications, they can be more easily matched and replaced with other components. Consistent connecting components contribute to the consistency of the optical path, making the outgoing optical path more uniform and consistent. Stable connecting components help to maintain the stability of the overall structure of the device, thus contributing to improving the quality of image acquisition and the recognition accuracy. Because a stable structure can reduce problems such as image blurring and deformation caused by vibration or loosening.
