Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door locks, in particular to a split-fingerprint door lock. BACKGROUND

[0002] With the development of technology and the increasing demand for safety, traditional mechanical door locks gradually cannot meet the safety needs of users in daily life and commercial places. Biometric technology, Bluetooth communication technology and other intelligent electronic identification technologies are gradually applied to door locks. As a new type of intelligent door lock, the split-fingerprint door lock realizes higher flexibility and security by separating the electronic identification module and the mechanical lock body.

[0003] However, the existing split-fingerprint door lock is mostly installed by using self-tapping screws on the side wall of the door panel facing outward. This type of split-fingerprint door lock not only has certain limitations on the material of the door panel, but also has the risk of being disassembled. Specifically, when the user twists the first mounting seat of the split-fingerprint door lock away from the inner panel, the fixing screws on the inner panel will be exposed. At this time, the door lock can be directly disassembled from the outside of the door, which is very unfavorable for the protection of the door lock. In addition, the method of fixing the door lock from the outside of the door using self-tapping screws is only suitable for wooden door panels. This type of split-fingerprint door lock is not suitable for installation on stainless steel, alloy and other door panels with higher hardness and rigidity, and the adaptability of the split-fingerprint door lock is low. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to provide a split-fingerprint door lock which fixes the first mounting seat from the inner side of the door panel through the second mounting seat, and hides the connecting piece and the mounting part in the lock hole, so that it is difficult for people outside the security door to observe and touch the mounting structure of the split-fingerprint door lock, thereby improving the installation reliability and use adaptability of the split-fingerprint door lock.

[0005] The embodiments of the present application are implemented as follows:

[0006] In a first aspect, the embodiments of the present application provide a split-fingerprint door lock, which comprises a mounting seat assembly and a fingerprint identification assembly. The fingerprint identification assembly is connected with the mounting seat assembly. The split-fingerprint door lock is installed on a door panel having a lock hole. The mounting seat assembly comprises a first mounting seat, a second mounting seat and a connecting piece. The first mounting seat comprises a mounting base plate and a mounting part. The mounting base plate has a first surface which is attached to one side of the door panel and used to cover the lock hole. The mounting part is arranged on the first surface and accommodated in the lock hole. The connecting piece is accommodated in the lock hole. One end of the connecting piece is connected with the mounting part, and the other end of the connecting piece is connected with the second mounting seat.

[0047] In the embodiments of the present application, the lock through hole 100 refers to a hole reserved on the door plate 10, used for mounting the split fingerprint door lock 2 and penetrating the inner side surface 102 of the door plate and the outer side surface 101 of the door plate; the mounting seat assembly 3 refers to a structure used for fixing and supporting the split fingerprint door lock 2; the fingerprint identification assembly 4 refers to a device capable of verifying the identity of a door opening user through a fingerprint verification mode and capable of driving a corresponding lock body to be unlocked; the first mounting seat 31 refers to a structure mounted on the outer side surface 101 of the door plate; the second mounting seat 32 refers to a structure mounted on the inner side surface 102 of the door plate and capable of cooperating with the first mounting seat 31 through the connecting piece 33 to clamp the door plate 10; the connecting piece 33 refers to an element connecting the first mounting seat 31 and the second mounting seat 32 together; the mounting base plate 310 refers to a plate structure closely attached to the outer side surface 101 of the door plate; and the mounting portion 311 refers to a structure used for connecting with the connecting piece 33.

[0048] Specifically, the mounting portion 311 can be provided in the form of a screw mounting column, the connecting piece 33 is twisted on the screw mounting column through the through hole of the second mounting seat 32 and the lock through hole 100, so that the split fingerprint door lock 2 can be fixed on the door plate 10, and meanwhile the second mounting seat 32 hides the connecting piece 33 and the fixed part of the connecting piece 33, which not only makes the door lock beautiful, but also improves the situation that the split fingerprint door lock 2 can be removed from the outside of the security door 1 due to the exposure of the connecting piece 33 to the outside of the security door 1.

[0049] In the above technical solution, the first mounting seat 31 and the second mounting seat 32 clamp the door plate 10 from both sides of the door plate 10 through the connecting piece 33 to be fixed at the lock through hole 100, which improves the installation stability of the split fingerprint door lock 2; the second mounting seat 32 fixes the first mounting seat 31 from the inner side surface 102 of the door plate, and the connecting piece 33 and the mounting portion 311 are hidden in the lock through hole 100, which makes it difficult for people outside the security door 1 to observe and touch the installation and fixing structure of the split fingerprint door lock 2, improves the external anti-removal ability (i.e. protection ability) and use reliability of the split fingerprint door lock 2; the split fingerprint door lock 2 can be adapted to door plates 10 of different thicknesses through the selection of the length of the connecting piece 33, which improves the flexibility and applicability of installation and is convenient and efficient; the mounting base plate 310 is attached to one side of the door plate 10, which can cover the lock through hole 100 and the connecting part in the hole, and improves the beauty and neatness of the split fingerprint door lock 2 in appearance.

[0050] Please refer to Figures 10 to 11 , Figure 10 the partial cross-sectional view of the split fingerprint door lock 2 shown in some embodiments of the present application; Figure 11 the partial exploded view of the split fingerprint door lock 2 shown in some embodiments of the present application. As Figures 7 to 11As shown, the fingerprint identification assembly 4 can include a fingerprint unlocking module 40 and a circuit board 41, and the mounting seat assembly 3 further includes a mainboard mounting shell 34; the fingerprint unlocking module 40 and the circuit board 41 are electrically connected, and the mainboard mounting shell 34 is provided with a fixing frame 340, the fingerprint unlocking module 40 is arranged on the fixing frame 340, and the mainboard mounting shell 34 is connected with the first mounting seat 31.

[0051] In the related art, the fingerprint unlocking module 40 of the split fingerprint door lock 2 is usually fixed directly through the circuit board 41, and when the user presses the fingerprint module, the force is directly transmitted to the circuit board 41, and the components on the circuit board 41 are prone to damage, and the service life of the split fingerprint door lock 2 is shortened.

[0052] In the embodiment of the present application, the fingerprint unlocking module 40 is used for detecting and comparing fingerprint information, the circuit board 41 can transmit the signal sent by the fingerprint unlocking module 40 to the lock body to control the unlocking of the lock body; the circuit board 41 can have a type-c charging port to realize the charging function of the split fingerprint door lock 2. The fingerprint unlocking module 40 has a fingerprint identification and comparison function, and the fingerprint unlocking module 40 is arranged on the fixing frame 340 of the mainboard mounting shell 34, thereby reducing the probability that the force directly acts on the circuit board 41 when the user presses the fingerprint unlocking module 40, i.e. reducing the damage probability of the circuit board 41, and prolonging the service life of the circuit board 41 and the split fingerprint door lock 2.

[0053] In some embodiments, the mounting seat assembly 3 further includes a first cover plate 35, and the first cover plate 35 is connected with the mainboard mounting shell 34; the fingerprint unlocking module 40 and the circuit board 41 are arranged between the first cover plate 35 and the mainboard mounting shell 34, and the mainboard mounting shell 34 and the mounting base plate 310 can be attracted and positioned by the magnetic member 30.

[0054] Specifically, the fastener 381 such as a screw can fix the mainboard mounting shell 34 on the first cover plate 35 through the through hole on the mainboard mounting shell 34. Figure 11 As shown, the screw is fixed on the threaded column in the first cover plate 35 through the three through holes on the mainboard mounting shell 34. In the case that the mainboard mounting shell 34 and the first cover plate 35 are assembled, the fixing frame 340 on the mainboard mounting shell 34 abuts against the fingerprint unlocking module 40 on the first cover plate 35, and the first cover plate 35 can be provided with a fingerprint pressing through hole 350 for exposing the fingerprint extraction surface of the fingerprint unlocking module 40. When the user presses the fingerprint unlocking module 40, the pressing force directly acts on the fingerprint unlocking module 40, and then the pressing force is transmitted to the mainboard mounting shell 34 through the fixing frame 340. The circuit board 41 will not be damaged due to excessive force or long-term force, i.e. the service life of the circuit board 41 and the split fingerprint door lock 2 is prolonged.

[0055] Specifically, the first mounting seat 31 has a magnetic element accommodating hole 312, and the magnetic element 30 (for example, a magnetic steel) is installed in the magnetic element accommodating hole 312, thereby enhancing the suction capacity between the first mounting seat 31 and the first cover plate 35 or the main plate mounting shell 34; the magnetic steel can be directly attracted to the fastener 381 used for connecting the main plate mounting shell 34 and the first cover plate 35, or can be attracted to the magnetic element 30 arranged on the main plate mounting shell 34 or the first cover body. The first cover plate 35 generally has a mounting cavity 351 of the main plate mounting shell 34 and the first mounting seat 31, and the size of the first cover plate 35 can be set to be consistent with a conventional lock core 5 cover, so as to facilitate direct replacement.

[0056] In the technical solution, the first cover plate 35 provides a protective barrier for the first mounting seat 31 and the fingerprint identification assembly 4, thereby reducing the probability of damage of the fingerprint identification assembly 4 due to external pollution or impact; the design of the magnetic element 30 adsorbed to the position makes the fitting between the main plate mounting shell 34 (or the first cover plate 35) and the first mounting seat 31 more convenient and fast, and the main plate mounting shell 34 (or the first cover plate 35) is easily removed from the first mounting seat 31 in a misaligned manner; the magnetic element 30 adsorption also improves the stability of the fitting connection between the main plate mounting shell 34 (or the first cover plate 35) and the first mounting seat 31, and reduces the probability of separation of the first cover plate 35 from the first mounting seat 31.

Please refer to Figures 6 to 7 、 Figure 9 、 Figures 12 to 13 As shown in FIGS. 1 to 3, the mounting seat assembly 3 further includes a second cover plate 36, and the second cover plate 36 is buckled on the outer periphery of the second mounting seat 32, and the second cover plate 36 and the second mounting seat 32 are connected through a screwing structure 37.

[0058] In the embodiments of the present application, the second cover plate 36 refers to a protective cover arranged on the outer periphery of the second mounting seat 32, and the screwing structure 37 is a mechanical structure for realizing connection and fixation through rotation. In the technical solution, the arrangement of the second cover plate 36 reduces the entry of dust, water vapor and the like into the second mounting seat 32 and the lock core through hole 313, thereby prolonging the service life of the split fingerprint door lock 2 on the door plate 10; the screwing structure 37 makes the installation and dismounting of the second cover plate 36 more convenient, realizes the accurate alignment and reliable connection of the second cover plate 36 and the second mounting seat 32, and reduces the probability of loosening or displacement.

[0059] In some embodiments, the screwing structure 37 comprises a limiting boss 371 and a limiting groove 372, the limiting boss 371 is arranged on the circumferential inner wall of the second cover plate 36, the limiting groove 372 is arranged on the circumferential outer wall of the second mounting seat 32, and one end of the limiting groove 372 is provided with an axial limiting block 373; in the case where the second cover plate 36 is connected with the second mounting seat 32 (in the second relative screwing position), the limiting boss 371 is accommodated in the limiting groove 372 and located at one end of the limiting groove 372, and the axial limiting block 373 is used to block the axial movement of the limiting boss 371.

[0060] Specifically, the limiting groove 372 extends circumferentially on the circumferential outer wall of the second mounting seat 32, so that when the second cover plate 36 rotates, the limiting boss 371 can move in the limiting groove 372 from one end away from the axial limiting block 373 to one end close to the axial limiting block 373. In the embodiments of the present application, the limiting boss 371 refers to a protruding structure arranged on the circumferential inner wall of the second cover plate 36, which is used to cooperate with the limiting groove 372 to realize the accurate alignment and connection between the second cover plate 36 and the second mounting seat 32; the circumferential limiting block refers to a blocking structure arranged at one end of the limiting groove 372, which can block the axial movement of the limiting boss 371 along the second mounting seat 32, so as to realize the stable connection between the second cover plate 36 and the second mounting seat 32.

[0061] In the above technical solution, the design of the limiting boss 371 and the limiting groove 372 realizes the accurate alignment between the second cover plate 36 and the second mounting seat 32; the axial limiting block 373 effectively prevents the axial movement of the limiting boss 371 and the second cover plate 36, so that the connection between the second cover plate 36 and the second mounting seat 32 is more stable, and the risk of loosening of the second cover plate 36 due to vibration or external force is reduced; the design of the limiting boss 371 and the limiting groove 372 makes the installation and disassembly of the second cover plate 36 very convenient, and the user only needs to guide the limiting boss 371 into the limiting groove 372 and then screw the second cover plate 36 in the correct rotation direction to complete the installation.

[0062] In some embodiments, the circumferential outer wall of the second mounting seat 32 is further provided with a boss guiding gap 374, one boss guiding gap 374 is communicated with one limiting groove 372, and the boss guiding gap 374 is used to guide the limiting boss 371 into the limiting groove 372. Specifically, the boss guiding gap 374 usually extends along the axial direction of the second mounting seat 32. In the above technical solution, the boss guiding gap 374 provides a clear guiding path for the limiting boss 371, so that the limiting boss 371 can efficiently enter the limiting groove 372, and the installation efficiency of the second cover body is improved.

[0063] In some embodiments, the second cover plate 36 and the second mounting base 32 can also be fixed by a radially inserted fastening screw 382 to reduce the probability of loosening of the second cover plate 36 and improve the connection firmness of the second cover plate 36 and the second mounting base 32. The screwing structure 37 can be provided with multiple groups, the circumferential inner wall of the second cover plate 36 is provided with a flat position boss 361, and the circumferential outer wall of the second mounting base 32 is provided with an axially extending flat position gap 362 (which can be understood as a boss guide-in gap 374 with a shape different from the limiting boss 371 and corresponding to the flat position boss 361 in shape and size). The flat position boss 361 is accommodated in the flat position gap 362 to limit the installation direction of the second cover plate 36 on the second mounting base 32. In the above technical solution, when the screwing structure 37 is provided with multiple groups, the cooperation of the flat position boss 361 and the flat position gap 362 can improve the problem of reverse installation of the second cover plate 36 on the second mounting base 32, so as to facilitate the smooth insertion of the fastening screw 382, and thus improve the assembly efficiency and assembly reliability of the mounting base assembly 3.

[0064] The assembly process of the second cover plate 36 and the second mounting base 32 is as follows: the second cover plate 36 is installed on the second mounting base 32 through the cooperation of the limiting boss 371 and the limiting groove 372 and the cooperation of the flat position boss 361 and the flat position gap 362, which can prevent the reverse installation of the second cover plate 36. At this time, the second cover plate 36 and the second mounting base 32 are in the first relative screwing position; then, the user can rotate the second cover plate 36 according to the specified rotation direction until it cannot continue to be screwed in, the limiting boss 371 accommodated in the limiting groove 372 moves from one end away from the axial limiting block 373 to one end close to the axial limiting block 373, at this time, the second cover plate 36 and the second mounting base 32 are in the second relative screwing position. When the second cover plate 36 and the second mounting base 32 are in the second relative screwing position, the axial limiting block 373 will block the limiting boss 371, so that the second cover plate 36 cannot be directly pulled out of the second mounting base 32. After the axial limiting block 373 blocks the limiting boss 371, the V-shaped groove on the second mounting base 32 will be aligned with the threaded hole on the second cover plate 36, at this time, the fastening screw 382 is screwed in until the fastening screw 382 abuts against the V-shaped groove and cannot continue to be screwed in, that is, the assembly of the second cover plate 36 and the second mounting base 32 is completed.

[0065] Please combine Figures 5 to 9As shown, in some embodiments, the connecting piece 33 is a tapered screw. In the embodiments of the present application, the tapered screw is fastened through the second mounting seat 32, the lock hole 100, and the mounting portion 311 on the first mounting seat 31, so that the mounting seats on both sides of the door plate 10 can be tightly attached to the door plate 10. If the thickness of the door plate 10 is relatively thin after installation, the tapered screw cannot clamp the first mounting seat 31 and the second mounting seat 32 to the door plate 10, and the operator can use pliers or other tools to trim the tapered screw to adapt to the thickness of the current door plate 10. In the above technical solution, the present application uses the tapered screw as the connecting piece 33, which can adapt the split fingerprint door lock 2 to different types of door plates 10, and can also adapt the tapered screw to door plates 10 of different thicknesses by trimming, thereby improving the adaptability of the split fingerprint door lock 2 to the door plate 10.

[0066] Please refer to Figure 14 , Figure 14 The overall exploded view of the split fingerprint door lock 2 is shown in some embodiments of the present application. Please refer to Figures 7 to 14 As shown, the split fingerprint door lock 2 further comprises a lock cylinder 5, which is arranged between the mounting base plate 310 and the second mounting seat 32. The mounting base plate 310 has a lock cylinder through hole 313, and the lock hole 50 of the lock cylinder 5 is exposed through the lock cylinder through hole 313. In the embodiments of the present application, the lock hole 50 is the part of the lock cylinder 5 for inserting the key, which is used to realize the opening and closing of the lock. In the above technical solution, the split fingerprint door lock 2 integrates the lock cylinder 5 and the fingerprint identification assembly 4 together, so that the split fingerprint door lock 2 has both mechanical unlocking function and fingerprint unlocking function, thereby improving the practicability and flexibility of the split fingerprint door lock 2.

[0067] In some embodiments, the lock cylinder 5 comprises a lock hole portion 51 and a matching portion 52 arranged on one side of the lock hole portion 51. The length of the matching portion 52 is less than that of the lock hole portion 51. The matching portion 52 and the lock hole portion 51 form a corner space 53 at one end close to the lock hole 50. The mounting base plate 310 further has a threading through hole 314, and the corner space 53 is arranged on one side of the threading through hole 314.

[0068] When adapting to door plates 10 of different thicknesses, the mounting seat assembly 3 of the split fingerprint door lock 2 is prone to interfere with the lock cylinder 5. The lock cylinder 5 avoids interference through the corner space 53, which can form a gap for wiring between the lock cylinder 5 and the threading through hole 314 when the thickness of the door plate 10 is relatively thin, thereby reducing the wiring interference. The mounting base plate 310 of the first mounting seat 31 can simultaneously partially mask the lock cylinder 5 and hide the mounting portion 311 and the connecting piece 33. The first cover plate 35 and the mounting base plate 310 can cover the lock cylinder 5, thereby reducing the probability of damage to the lock cylinder 5 due to exposure. The mounting base plate 310 cooperates with the lock cylinder 5 to cover the mounting portion 311 and the connecting piece 33.

[0069] In some embodiments, the first cover plate 35 can be connected with the first mounting base 31 through the elastic stretching assembly 39; in the technical solution, the first cover plate 35 can be separated from the first mounting base 31 to expose the mounting substrate 310 or the lock hole 50 of the lock cylinder 5 without being completely separated from the mounting substrate 310, thereby improving the convenience of the split-fingerprint door lock 2. Specifically, the elastic stretching assembly 39 includes a spring 391 and a screw 392. The spring 391 is fixed in the spring hole 315 of the first mounting base 31 through the screw 392, and the screw 392 connects the first cover plate 35 with the first mounting base 31, and enables the first cover plate 35 and the first mounting base 31 to be separated and relatively rotated by a certain angle to expose the lock hole 50 of the lock cylinder 5. One end of the screw 392 is connected with the threaded column on the first cover plate 35, and the other end of the screw 392 abuts against the spring 391 in the spring hole 315 of the first mounting base 31.

[0070] The first cover plate 35 covers the lock cylinder 5 and the lock hole 50, and when the first cover plate 35 is unscrewed, the lock hole 50 is exposed to enable mechanical unlocking. Specifically, when a user needs to use a key to mechanically unlock the lock cylinder 5, the user can hold the side of the first cover plate 35 and pull it outward, at this time, the first cover plate 35 and the first mounting base 31 will be separated by a distance, and because of the length and elasticity of the spring 391, the first cover plate 35 will not be separated too far; at this time, the first cover plate 35 is rotated by being pushed to one side, and the edge of the first cover plate 35 will abut against the first mounting base 31, so that the first cover plate 35 and the first mounting base 31 are in a rotatable separated state, and the rotation is continued, and when the wire through hole 314 clamps the wire with the mainboard mounting shell 34, the first cover plate 35 cannot continue to rotate, that is, the maximum angle of rotation of the first cover plate 35 is reached, at this time, the lock hole 50 of the lock cylinder 5 is exposed through the lock cylinder through hole 313 on the first mounting base 31, and the user can use the mechanical lock cylinder 5 to unlock the door.

[0071] When the user finishes the mechanical unlocking operation, the mechanical key is pulled out, at this time, the first cover plate 35 can be reversely pushed to its original position. When the first cover plate 35 is returned to the original position, the first mounting base 31 can be embedded into the mounting cavity 351 of the first cover plate 35, the spring 391 releases the stored force in the compressed state to pull the first cover plate 35 back and make the first cover plate 35 adhere to the first mounting base 31; at the same time, the magnetic member 30 on the first mounting base 31 attracts the screw on the first cover plate 35 to assist the attraction, and the user completes the resetting operation of the first cover plate 35.

[0072] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
