TECHNICAL FIELD

[0003] The present application relates to the technical field of smart door locks, in particular to an identification assembly, a panel device and a smart lock. BACKGROUND

[0004] With the rapid development of mobile Internet, Internet of Things and other technologies, biometric identification technology is increasingly widely used in the field of identity authentication. Among them, fingerprint identification, as one of the earliest and most mature biometric identification technologies, has become an indispensable identity verification method in many devices and systems due to its unique uniqueness and invariability. The fingerprint identification system includes key parts such as fingerprint identification sensor, feature extraction / matching module, feature template library and application software. In the identification process, the matching of fingerprints first needs to extract the features of the fingerprint to be verified, and compare them with the template fingerprints in the fingerprint template library, so as to judge whether the two fingerprint images come from the same finger. Therefore, the accuracy and integrity of fingerprint collection are crucial to the identification result.

[0005] The identification area of the fingerprint identification sensor is generally set as a planar structure, which often has the problems of poor adhesion to the finger and weak comfort in actual use. In the related technology, the identification area of the fingerprint identification device lacks a finger profiling structure, so that the user cannot guide and limit the finger when pressing the finger for fingerprint identification, affecting the efficiency of fingerprint identification. SUMMARY

[0006] Therefore, the present application provides an identification assembly, a panel device and a smart lock to solve the problems of weak comfort and low identification success rate caused by the lack of profiling structure and poor adhesion to the finger in the existing fingerprint identification system.

[0007] In a first aspect, the present application provides an identification assembly, comprising:

[0008] The guide base is provided with a groove, and the groove is provided with an identification area, and the area between the edge of the identification area and the groove is provided with a profiling area, and the profiling area is provided with a curved surface suitable for the fingers.

[0009] Beneficial effects: By setting a groove of a certain depth on the contact part, not only the physical fit of the identification component and the finger is improved, but also the contact area of the finger and the sensor is enhanced, significantly improving the acquisition quality and integrity of the fingerprint image, thereby improving the accuracy and speed of fingerprint identification. Under the joint action of the groove and the profiling area, the sliding and displacement of the finger during the identification process is reduced, and the comfort of the user during use is significantly enhanced. The identification area can be set as a flat surface or a curved surface, providing flexibility in design to meet the needs of different scenarios and applications.

[0010] Need to be explained, the above-mentioned identification area can be set at the bottom of the groove, or in the middle area from the bottom of the groove to the edge of the groove, and in the case of the above-mentioned identification area being set in the middle area from the bottom of the groove to the edge of the groove, the bottom of the groove can also have no identification area. These embodiments can achieve the purpose of the present application and achieve the above technical effects.

[0011] In an optional embodiment, the radius of curvature of the profiling area is R, wherein 200mm≥R≥10mm.

[0012] Beneficial effects: By setting the radius of curvature range of the profiling area, it is ensured that the sensor can cover and adapt to the shape of most people's fingers, and good fit and identification effect can be obtained regardless of the thickness of the finger.

[0013] In an optional embodiment, the identification area is set as a curved surface, and the radius of curvature of the identification area is equal to the radius of curvature of the profiling area.

[0014] Beneficial effects: When the identification area is set as a curved surface, it has the same radius of curvature as the profiling area, and this consistency ensures that the finger can obtain uniform contact pressure in the entire groove area, thereby improving the clarity and identification accuracy of the fingerprint image.

[0015] In an optional embodiment, the identification area and the profiling area are configured as a complete curved surface structure.

[0016] Beneficial effects: The identification area and the profiling area are configured as a complete curved surface structure, eliminating possible edges or abrupt points, making the finger more smooth when sliding or pressing, reducing friction and discomfort, and also helping to improve the stability of fingerprint identification.

[0017] In an optional embodiment, the depth of the identification area is B, wherein 0.1mm≤B≤5mm.

[0018] Beneficial effect: The depth range of the identification area is set to ensure sufficient fingerprint information collection while considering the comfort of finger touch, avoiding the inconvenience caused by too deep or too shallow grooves.

[0019] In an optional embodiment, the identification area is set as a plane, and the diameter of the identification area is C, wherein 1mm≤C≤30mm.

[0020] Beneficial effect: When the identification area is set as a plane, its diameter range is set to ensure sufficient fingerprint collection area and control the overall size of the sensor, facilitating integration into various intelligent door locks and other small devices.

[0021] In an optional embodiment, the profiling area is transitionally connected with the identification area.

[0022] Beneficial effect: The transitionally connected setting of the profiling area and the identification area ensures smooth transition of the finger when entering the identification area from the profiling area, reduces discomfort caused by shape changes, and also ensures the continuity and integrity of fingerprint image collection.

[0023] In an optional embodiment, the contact part is set as a cylindrical structure or a prismatic structure.

[0024] Beneficial effect: The contact part is set as a cylindrical structure or a prismatic structure, providing diversified design options, making the identification assembly more easily integrated into products of different styles and design concepts, enhancing its market adaptability and competitiveness.

[0025] In an optional embodiment, the identification area is set parallel to the plane surrounded by the edge of the groove.

[0026] Beneficial effect: When performing finger pressing identification, the identification area can be aligned with the center position of the finger instead of the edge position, increasing the identification accuracy.

[0027] In an optional embodiment, the depth of the groove is A, wherein 0.1mm≤A≤5mm.

[0028] In an optional embodiment, the area between the edge of the identification area and the notch further comprises a guide area, the identification area, the profiling area and the guide area are connected in sequence from the direction along the bottom of the groove to the notch, the identification area is divided into a first identification area and a second identification area, the second identification area at least partially overlaps with the profiling area, the first identification area is adapted to contact the first area of the finger, and the second identification area is adapted to contact the second area of the finger.

[0029] Beneficial effects: By setting the guiding base with a curved groove, and setting the groove wall to match the natural curvature of the finger, the adhesion of the finger and the recognition area can be significantly improved. By setting the first recognition area, the second recognition area and the guiding area in the groove along the first direction in turn, not only the area layout of the fingerprint information collection is optimized, but also the possibility of misoperation is reduced by guiding the user to place the finger correctly through the design of the guiding area. The joint use of the first recognition area and the second recognition area can comprehensively identify the center area of the finger and the edge of the finger, improve the stability of the identification process, and at the same time improve the accuracy.

[0030] It should be noted that the first recognition area corresponds to the center area of the finger (usually rich in feature points, usually the main recognition area), and the second recognition area corresponds to the edge area of the finger (fewer recognition points, usually the auxiliary recognition area); the first recognition area can be a plane, a curved surface, or a combination of a plane and a curved surface, all of which can achieve the purpose of the present application and achieve the above technical effects.

[0031] In an optional embodiment, the curvature diameter of the first recognition area is greater than the curvature diameter of the second recognition area, and the curvature diameter of the second recognition area is greater than the curvature diameter of the profiling area.

[0032] Beneficial effects: The first recognition area, the second recognition area and the guiding area adopt different curvature diameters, which further enhances the adhesion of the finger and the recognition surface, and ensures the comprehensiveness and accuracy of the fingerprint information collection. The curvature diameter of the guiding area is the smallest, which can guide the finger, so that the finger moves more accurately when it is inserted into the groove, avoiding the situation of incomplete contact, and improving the recognition accuracy. The curvature diameter of the second recognition area is greater than the curvature diameter of the guiding area, which can reduce the design difficulty of the algorithm, and the slope can make the fingerprint recognition more accurate. The curvature diameter of the first recognition area is the largest, which can make the slope the most gentle, and facilitate the identification of the center area of the finger.

[0033] In an optional embodiment, the curvature diameter of the first recognition area is set to A2, wherein 0.1mm≤A2≤1000mm.

[0034] Beneficial effects: By setting the curvature diameter range of the first recognition area (0.1mm≤A2≤1000mm), it is ensured that this area can adapt to the curvature of different fingers and ensure sufficient recognition accuracy.

[0035] In an optional embodiment, the curvature diameter of the second recognition area is set to B2, wherein 0.1mm≤B2≤1000mm.

[0036] Beneficial effect: The curvature diameter range (0.1mm≤B2≤1000mm) of the second identification area is set, so that the area can better fit the edge of the finger, and the collection efficiency of the fingerprint information is improved.

[0037] In an optional embodiment, the curvature diameter of the guide area is set as C2, wherein 0.1mm≤C2≤1000mm.

[0038] Beneficial effect: The curvature diameter range (0.1mm≤C2≤1000mm) of the guide area helps to guide the natural transition of the finger to the identification area, and improves the user's experience.

[0039] In an optional embodiment, a base is further included, which is connected with the guide base, and the base and the guide base are arranged in sequence along the first direction.

[0040] Beneficial effect: The combination design of the base and the guide base not only enhances the structural stability of the fingerprint identification assembly, but also provides a reliable mounting platform for the fingerprint identification sensor.

[0041] In an optional embodiment, a fingerprint identification sensor is further included, which is arranged in the base and is adapted to acquire the fingerprint information of the central area and the edge of the finger.

[0042] Beneficial effect: The fingerprint identification sensor arranged in the base can accurately acquire the fingerprint information of the central area and the edge of the finger, and improves the accuracy and reliability of identification.

[0043] In an optional embodiment, the first identification area, the second identification area and the guide area are connected in sequence along the first direction, and the connection positions of the first identification area and the second identification area are smoothly transitioned, and the connection positions of the second identification area and the guide area are smoothly transitioned.

[0044] Beneficial effect: Since the curvature diameters of the first identification area, the second identification area and the guide area are different, when the first identification area, the second identification area and the guide area are spliced, sharp corners or sharp concave structures will be generated at the splicing positions between any two of them. Therefore, when the first identification area, the second identification area and the guide area are arranged, the transition areas of the three can be chamfered. The smooth transition design between the first identification area, the second identification area and the guide area ensures the comfort of the finger during movement, and avoids identification failure caused by abrupt transition.

[0045] In an optional embodiment, the height of the first identification area along the first direction is less than the height of the second identification area along the first direction, and the height of the second identification area along the first direction is less than the height of the guide area along the first direction.

[0046] Beneficial effects: By adjusting the height of each identification area along the first direction, the contact area and the fit degree of the finger and the identification surface are further optimized, and the stability and success rate of identification are improved.

[0048] Beneficial effects: The groove on the guide base is set as a curved surface that matches the finger, which can reduce the deformation of the fingerprint of the user's finger during pressing, ensuring the identification effect. At the same time, setting the groove as a curved surface that matches the curvature of the finger can increase the comfort of the user during the fingerprint identification process, and by increasing the fit degree of the groove and the finger, a guiding effect can be achieved to ensure the identification quality and efficiency. The identification part is transitionally connected with the edge of the hole of the through hole, which can smoothly transition the guide base and the identification area, improve the comfort, ensure the identification effect, and also realize the embedding of the guide base and the base to achieve stable connection between the two.

[0049] It should be noted that the end face of the protruding part provided with the identification part away from the base can have an area larger than the cross-sectional area of the through hole, so that the identification area is formed by the abutment of the end face and the bottom of the through hole. At this time, the depth (axial length) of the through hole should be as small as possible. Alternatively, the protruding part can penetrate the through hole, so that the end face of the protruding part provided with the identification part away from the base is located inside the through hole or slightly protrudes above the through hole.

[0088] The guide base 1 is adapted to be touched by a user's finger, and a groove is arranged on the guide base 1, the depth of the groove being A2, wherein 0.1mm≤A≤5mm.

[0104] In some embodiments, the profiling area 2 has a radius of curvature R, wherein 200mm≥R≥10mm.

[0105] In this embodiment, the curvature radius range of the profiling area 2 is set to ensure that the sensor can cover and adapt to the finger shapes of most people, regardless of finger thickness, to obtain good fit and recognition effect.

[0106] In some embodiments, the recognition area 3 is arranged in parallel with the plane surrounded by the edge of the groove.

[0107] In this embodiment, when performing finger pressing recognition, the recognition area can be aligned with the center position of the finger instead of the edge position, thereby increasing the recognition accuracy.

[0108] In some embodiments, the curvature radius of the profiling area changes with the depth of the groove according to ergonomics, and the optimal arc area and curvature for the best experience of the thumb and index finger of Asians are found.

[0109] In this embodiment, the dynamic change of the curvature radius of the profiling area 2 with the depth of the groove enables the sensor to more accurately match the natural curvature of different fingers, and even in the case of slight finger movement or different pressing force, stable recognition performance can be maintained.

[0110] In some embodiments, when the recognition area 3 is arranged in a curved surface state, the curvature radius of the recognition area 3 is equal to that of the profiling area 2.

[0123] The embodiments of the present application are described below in conjunction with FIGS. 5-6.

[0124] According to the embodiments of the present application, in one aspect, a fingerprint identification assembly is provided, which is set in a first direction X and includes a guide base 21 adapted for a user's finger to touch, an outer side wall of the guide base 21 is provided with a groove, a groove wall of the groove is set as a curved surface adapted to match the finger; wherein the groove wall is sequentially provided with a first identification area 231, a second identification area 232 and a guide area 4 along the first direction X, the first identification area 231 is adapted to contact the central area of the finger, the second identification area 232 is adapted to contact the edge of the finger, and the guide area 4 is adapted to guide the finger in the reverse direction of the first direction X.

[0125] It should be noted that, as shown in FIG. 6, the first identification area 231 is arranged at the groove bottom surface of the groove, and is specifically arranged as a reverse concave surface in the first direction X, so as to be in contact with the circular surface of the center area of the finger, and the fingerprint information of the center area of the finger of the user is acquired through the fingerprint identification sensor. The second identification area 232 is arranged at the middle part of the groove, and is arranged as a ring structure in the plane perpendicular to the first direction X, and the second identification area 232 is arranged as an arc surface, and the cross-sectional area of the second identification area 232 perpendicular to the first direction X gradually increases along the first direction X, so that the second identification area 232 is in contact with the ring surface of the edge area of the finger, and the fingerprint information of the edge of the finger of the user is acquired through the fingerprint identification sensor. The guide area 4 is arranged at the top of the groove, and is arranged as a ring structure in the plane perpendicular to the first direction X, and the guide area 4 is arranged as an arc surface, and the cross-sectional area of the guide area 4 perpendicular to the first direction X gradually increases along the first direction X.

[0126] In the embodiment, the guide base 21 with the curved groove is arranged, and the groove wall is matched with the natural curvature of the finger, so that the adhesion of the finger and the identification area is significantly improved. The first identification area 231, the second identification area 232 and the guide area 4 are sequentially arranged in the groove along the first direction X, which not only optimizes the area layout of the fingerprint information acquisition, but also guides the user to correctly place the finger through the design of the guide area 4, reduces the possibility of misoperation, and the joint use of the first identification area 231 and the second identification area 232 can comprehensively identify the center area of the finger and the edge of the finger, improve the stability of the identification process, and improve the accuracy.

[0127] In one embodiment, the curvature diameter of the first identification area 231 is greater than the curvature diameter of the second identification area 232, and the curvature diameter of the second identification area 232 is greater than the curvature diameter of the guide area 4.

[0128] It can be understood that the curvature diameter of the first identification area 231 refers to the curvature diameter of the arc line in the cross section along the first direction X as shown in FIG. 6. The curvature diameter of the second identification area 232 refers to the curvature diameter of the arc line in the cross section along the first direction X as shown in FIG. 6. The curvature diameter of the guide area 4 refers to the curvature diameter of the arc line in the cross section along the first direction X as shown in FIG. 6.

[0129] In the embodiment, the first identification area 231, the second identification area 232 and the guide area 4 are designed with different curvature diameters, which can enhance the adhesion of the finger to the identification surface and ensure the comprehensiveness and accuracy of the fingerprint information collection. Meanwhile, the curvature diameter A2 of the first identification area 231 is greater than the curvature diameter B2 of the second identification area 232, which is greater than the curvature diameter C2 of the guide area 4, further enhancing the adhesion of the finger to the identification surface. The curvature diameter of the guide area 4 is the smallest, which can guide the finger, so that the finger moves more accurately when it is inserted into the groove, avoiding the situation of incomplete contact and improving the identification accuracy. The curvature diameter of the second identification area 232 is greater than the curvature diameter of the guide area 4, which can reduce the design difficulty of the algorithm, and the slope can be reduced to make the fingerprint identification more accurate. The curvature diameter of the first identification area 231 is the largest, which can make the slope the most gentle, facilitating the identification of the central area of the finger.

[0130] In one embodiment, the groove wall of the groove provided on the guide base 21 needs to be spliced with a curved surface greater than a certain length, and the curved surface arc splicing process needs smooth transition; the first identification area 231 and the second identification area 232 provided in the groove are more gentle relative to the guide area 4, which can reduce the algorithm difficulty and improve the processing accuracy.

[0131] In one embodiment, the curvature diameter of the first identification area 231 is set as A2, wherein 0.1mm≤A2≤1000mm.

[0132] Alternatively, the curvature diameter A2 of the first identification area 231 can be set as 500mm, at this time the curvature diameter B2 of the second identification area 232 is less than 500mm, and the curvature diameter C2 of the guide area 4 is less than the curvature diameter B2 of the second identification area 232.

[0133] Alternatively, the curvature diameter A2 of the first identification area 231 can be set as 1000mm, at this time the curvature diameter B2 of the second identification area 232 is less than 1000mm, and the curvature diameter C2 of the guide area 4 is less than the curvature diameter B2 of the second identification area 232.

[0134] In the embodiment, by setting the curvature diameter range (0.1mm≤A2≤1000mm) of the first identification area 231, it is ensured that the area can adapt to the radii of different fingers and also ensure sufficient identification accuracy.

[0135] In one embodiment, the curvature diameter of the second identification area 232 is set as B2, wherein 0.1mm≤B2≤1000mm.

[0136] Alternatively, the curvature diameter B2 of the second identification area 232 can be set as 500mm, at this time the curvature diameter A2 of the first identification area 231 is greater than 500mm, and the curvature radius C2 of the guide area 4 is less than 500mm.

[0137] In the embodiment, the curvature diameter range of the second identification area 232 (0.1mm≤B2≤1000mm) is set so that the area can better fit the edge of the finger and improve the collection efficiency of the fingerprint information.

[0138] In one embodiment, the curvature diameter of the guide area 4 is set as C2, where 0.1mm≤C2≤1000mm.

[0139] Alternatively, the curvature diameter C2 of the guide area 4 can be set as 500mm, and the curvature diameter B2 of the second identification area 232 is greater than 500mm, and the curvature diameter A2 of the first identification area 231 is greater than the curvature diameter B2 of the second identification area 232.

[0140] Alternatively, the curvature diameter C2 of the guide area 4 can be set as 0.1mm, and the curvature diameter B2 of the second identification area 232 is greater than 0.1mm, and the curvature diameter A2 of the first identification area 231 is greater than the curvature diameter B2 of the second identification area 232.

[0141] In the embodiment, the setting of the curvature diameter range of the guide area 4 (0.1mm≤C2≤1000mm) helps to guide the natural transition of the finger to the identification area and improves the user experience.

[0142] In one embodiment, the curvature diameter A2 of the first identification area 231, the curvature diameter B2 of the second identification area 232 and the curvature diameter C2 of the guide area 4 can be set as equal values.

[0143] In one embodiment, the base 5 is further included, the base 5 is connected with the guide base 21, and the base 5 and the guide base 21 are arranged in sequence along the first direction X.

[0144] Alternatively, the cross section of the base 5 perpendicular to the first direction X can be set as one of a circle, a circle-like shape, and a regular polygon. The cross section of the guide base 21 perpendicular to the first direction X can be set as one of a circle, a circle-like shape, and a regular polygon.

[0145] Alternatively, the cross section area of the base 5 perpendicular to the first direction X is greater than the cross section area of the guide base 21 perpendicular to the first direction X.

[0146] In the embodiment, the combination design of the base 5 and the guide base 21 not only enhances the structural stability of the fingerprint identification assembly, but also provides a reliable mounting platform for the fingerprint identification sensor.

[0147] In one embodiment, the fingerprint identification sensor is further included, and the fingerprint identification sensor is arranged in the base 5 and is adapted to acquire the fingerprint information of the central area of the finger and the edge of the finger.

[0148] It should be noted that the fingerprint recognition sensors are provided in plurality, and the plurality of fingerprint recognition sensors are equidistantly arranged along the circumference of the guide base 21 and located directly below the second recognition area 232. Since the fingerprint recognition sensors receive the fan-shaped structure externally, the first recognition area 231 and the second recognition area 232 share the plurality of fingerprint sensors.

[0149] In the embodiment, the fingerprint recognition sensors are arranged in the base 5, and the fingerprint information of the center region of the finger and the edge of the finger can be accurately acquired, thereby improving the accuracy and reliability of the recognition.

[0150] In one embodiment, the first recognition area 231, the second recognition area 232 and the guide area 4 are sequentially connected along the first direction X, and the connection position of the first recognition area 231 and the second recognition area 232 is smoothly transitioned, and the connection position of the second recognition area 232 and the guide area 4 is smoothly transitioned.

[0151] It can be understood that, since the curvature diameters of the first recognition area 231, the second recognition area 232 and the guide area 4 are different, when the first recognition area 231, the second recognition area 232 and the guide area 4 are spliced, a sharp corner or a sharp concave structure will be generated at the splicing position between any two of them, and therefore the transition regions of the first recognition area 231, the second recognition area 232 and the guide area 4 can be chamfered when they are arranged.

[0152] Alternatively, since the curvature diameters of the first recognition area 231, the second recognition area 232 and the guide area 4 are different, when the first recognition area 231, the second recognition area 232 and the guide area 4 are spliced, a sharp corner or a sharp concave structure will be generated at the splicing position between any two of them, and therefore when the first recognition area 231, the second recognition area 232 and the guide area 4 are arranged, a ring-shaped transition structure can be arranged between any two of them, so that the first recognition area 231, the second recognition area 232 and the guide area 4 are smoothly transitioned through the ring-shaped transition structure.

[0153] In the embodiment, the smoothly transitioned design between the first recognition area 231, the second recognition area 232 and the guide area 4 ensures the comfort of the finger during movement, and avoids recognition failure caused by abrupt transition.

[0154] In one embodiment, the height of the first recognition area 231 along the first direction X is less than the height of the second recognition area 232 along the first direction X, and the height of the second recognition area 232 along the first direction X is less than the height of the guide area 4 along the first direction X.

[0155] It can be understood that, in order to make it more convenient and accurate for the finger to enter the groove, the height of the guiding area 4 can be increased while the curvature diameter of the guiding area 4 is reduced, and the height of the guiding area 4 accounts for the largest proportion of the depth of the groove, so as to facilitate the user to quickly and accurately enter the finger into the groove and contact the first identification area 231 and the second identification area 232 and perform identification. In order to make the central area of the finger more accurately contact the third identification area, the height of the second identification area 232 can be reduced while the curvature diameter of the second identification area 232 is smaller than that of the guiding area 4, so that the second identification area 232 can be more fitted with the edge of the finger, and the algorithm difficulty can be reduced and the processing precision can be improved. The third identification area has the smallest curvature diameter, and the height of the third identification area is set to be the lowest, so that the third identification area forms a gentle area, the algorithm difficulty can be reduced and the processing precision can be improved.

[0156] In the embodiment, by adjusting the height of each identification area along the first direction X, the contact area and the fitting degree of the finger and the identification surface are further optimized, and the stability and success rate of identification are improved.
