Description

Technical Field

[0001] The utility model relates to the technical field of padlocks, in particular to a transmission structure of a fingerprint padlock and a fingerprint padlock. Background Art

[0002] With the progress of society and the improvement of people's living standards, the requirements for the safety and durability of padlocks are getting higher and higher. There are many types of padlocks on the market now, which can be divided into mechanical padlocks, electronic password padlocks and fingerprint padlocks according to their functions. Fingerprint padlocks have gradually replaced traditional mechanical padlocks and electronic password padlocks because of their convenience of not requiring keys or entering passwords, and have become the most popular padlock among users. Among them, some fingerprint padlocks include the function of dual opening with fingerprints and mechanical keys. This type of fingerprint padlock with dual opening needs to ensure the security of the fingerprint padlock while realizing the functions of fingerprint unlocking and mechanical key unlocking.

[0003] However, the transmission structure for unlocking the existing fingerprint padlock is generally complicated, which makes mechanical unlocking and electric unlocking inconvenient. The motor needs to drive multiple transmission parts to unlock and lock. When mechanically unlocking, multiple rounds of transmission are also required to unlock and lock. In the long run, the mechanical failure rate is high, which affects the service life of the lock. The complex mechanical structure will also increase the power consumption of the battery, resulting in a shorter battery life of the fingerprint padlock. On the other hand, there are too many internal locking and transmission parts, and the structure is relatively complex, which makes it impossible to reduce the volume, and the production cost remains high.

[0004] Therefore, how to provide a fingerprint padlock with a simple structure and a transmission structure thereof has become an important issue to be solved urgently by those skilled in the art. Utility Model Content

[0005] The utility model overcomes the shortcomings of the above-mentioned technology and provides a transmission structure of a fingerprint padlock and a fingerprint padlock.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A linkage mechanism is provided on the lock core body, and one end of the linkage mechanism is connected to the first rotating part. After the key is inserted into the lock core body, the linkage mechanism can rotate with the lock core body, thereby driving the first rotating part to rotate.

[0008] Furthermore, the linkage mechanism includes a first connecting member arranged in the lock core body, a second rotating member arranged at the upper end of the lock core body, and a spring connected between the first connecting member and the second rotating member. The linkage mechanism also includes a first limiting structure. After the key is inserted into the lock core body, the first connecting member can be pushed upward, and through the cooperation of the first limiting structure, the second rotating member can rotate with the lock core body.

[0009] Furthermore, the first limiting structure includes a first protrusion arranged at the top of the first connecting member, and a first cross bar connected to the lower end of the first protrusion. The first limiting structure also includes a first groove corresponding to the first protrusion inserted into the second rotating member and a slot located at the lower end of the first groove for the first cross bar to be inserted into.

[0010] Furthermore, the first rotating member is provided with a plurality of first teeth, and the second rotating member is provided with a plurality of second teeth that are convenient for meshing with the first teeth.

[0011] Furthermore, a recessed portion cooperating with a locking mechanism is provided on the lock beam, and the locking mechanism includes a rotating column connected to the upper end of the first rotating member and capable of rotating with the first rotating member, and a sphere that can be partially accommodated in the recessed portion, and the rotating column includes a second cross bar for causing the sphere to sink into / escape from the recessed portion when the rotating column rotates, and two recessed portions are symmetrically arranged, and two spheres are correspondingly symmetrically arranged, and the two spheres are connected and fixed by a torsion spring, and the second cross bar is arranged between the two spheres, and a second limiting structure is provided between the rotating column and the first rotating member.

[0012] Furthermore, the recessed portions are symmetrically arranged with two, the spheres are correspondingly symmetrically arranged with two, and the two spheres are connected and fixed by a torsion spring, the second cross bar is arranged between the two spheres, the second limiting structure includes a second groove opened at the upper end of the first rotating member, the rotating column also includes a connecting end arranged in the second groove, and the second groove is provided with a limiting protrusion for limiting the relative rotation angle of the first rotating member and the rotating column.

[0013] Furthermore, a reset mechanism for automatically resetting the rotating column is provided on the rotating column, and the reset mechanism can automatically sink into the recessed portion after the second cross bar separates the ball from the recessed portion.

[0014] A fingerprint padlock includes the transmission structure of the fingerprint padlock and a base. The base is provided with an installation cavity. The locking mechanism, the motor, and the mechanical lock core assembly are all fixedly installed in the installation cavity. The lock beam is pluggable and arranged on the base. A third limiting structure is also provided between the base and the first rotating member.

[0015] Furthermore, the third limiting structure includes a fan-shaped groove opened on the outer periphery of the first rotating member and a limiting block arranged on the base, and blocking parts are provided at both ends of the fan-shaped groove. When the first rotating member rotates, the limiting block is restricted to slide between the two blocking parts.

[0016] Furthermore, it also includes a battery and a fingerprint recognition module installed in the base, and also includes a front plate covering the base, the fingerprint recognition module includes a fingerprint collection panel, the front plate is provided with a first protective cover that can be slid open / closed and covers the fingerprint collection panel, and the lower end of the base is provided with a second protective cover that can be opened / closed.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. This case provides a transmission structure of a fingerprint padlock, which is achieved by sleeved a first rotating part on the motor and by setting a linkage mechanism on the body of the mechanical lock core assembly. When the user inserts the key into the lock core body, the linkage mechanism can be driven to rotate with the lock core body. Since the linkage mechanism is connected to the first rotating part, the first rotating part can be driven to rotate at the same time. Through the above simple structure, a mechanical switch lock is realized. On the other hand, when the motor rotates, it drives the first rotating part to rotate, thereby driving the locking mechanism to operate, so as to realize an electric switch lock. The overall structure of the transmission mechanism in this case is compact, the transmission stroke is short, and the transmission mechanism requires fewer parts as a whole. Only by setting the linkage mechanism and the first rotating part, the connection and drive between the mechanical lock core assembly, the motor and the locking mechanism are realized. The structure is relatively simple, which can effectively reduce the mechanical failure rate; at the same time, it can also reduce energy consumption, reduce battery power consumption, and extend service life.

[0019] 2. The linkage mechanism of this case can only rotate with the lock core body after the user inserts the key into the lock core body. When the user inserts the key into the lock core body, the linkage mechanism can be driven to rotate with the lock core body. Since one end of the linkage mechanism is connected to the first rotating member, the first rotating member can be driven to rotate at the same time. In other words, under normal circumstances, the first connecting member and the second rotating member are always kept separated. This structural design does not affect the user's use of another unlocking method to unlock the door even when one of the structures of the motor or mechanical lock core assembly fails. For example, when the motor fails, the user can use the key to unlock the door. When the keyhole is rusted or blocked, the key can be unlocked through the motor. It effectively solves the problem of users being unable to unlock the door, and improves the practicality of the fingerprint padlock of this case.

[0020] 3. The way in which the components of the fingerprint padlock are installed and arranged in this case is conducive to saving installation space, thereby reducing the overall volume of the fingerprint padlock and facilitating transportation, carrying and use.

[0032] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0033] like Figures 1 to 11As shown, this case provides a transmission structure of a fingerprint padlock, which specifically includes a lock beam 1, and a locking mechanism 2 connected to the lock beam 1 for driving the lock beam 1 to move up and down to lock / unlock. In specific implementation, the lock beam 1 is "U"-shaped, which is a common structure in the field. The transmission structure of the fingerprint padlock in this case also includes a motor 3 and a mechanical lock core assembly 4 for driving the locking mechanism 2. The motor 3 is used to drive the locking mechanism 2 in an electric manner to achieve locking / unlocking, so as to facilitate the user to use fingerprint unlocking, and the mechanical lock core assembly 4 is used by the user to use a key for mechanical unlocking, which is further convenient for the user. Among them, the mechanical lock core assembly 4 includes a lock core body 41 that is allowed to rotate only when the corresponding key is inserted, that is, the lock core body 41 keeps the mechanical lock core assembly 4 in a locked state. Only when the user inserts the lock core body 41 with a key can the lock core body 41 be relatively rotated, thereby unlocking the mechanical lock core assembly 4. The corresponding key refers to a key dedicated to the mechanical lock core assembly 4 in this case. Each lock has a corresponding key, which is common knowledge in the field. The motor 3 is provided with a first rotating member 7 for driving the locking mechanism 2. When the motor 3 rotates, the first rotating member 7 is driven to rotate, thereby driving the locking mechanism 2 to realize the electric switch lock. The lock core body 41 is provided with a linkage mechanism 8. When the user inserts the key into the lock core body 41, the linkage mechanism 8 can be driven to rotate with the lock core body 41. Since one end of the linkage mechanism 8 is connected to the first rotating member 7, the first rotating member can be driven to rotate at the same time. In other words, under normal conditions, the first connecting member 81 and the second rotating member 82 are always kept separated. When the user uses the key to mechanically unlock the lock, the key is inserted into the lock core body 41, and the linkage mechanism 8 can be driven to rotate by rotating the lock core body 41, thereby driving the first rotating member 7 to rotate, and finally realizing mechanical unlocking.

[0034] Specifically, Figure 1 , 2As shown in Figures 7 and 8, the linkage mechanism 8 includes a first connecting member 81 disposed in the lock core body 41, a second rotating member 82 disposed at the upper end of the lock core body 41, and a spring 83 connected between the first connecting member 81 and the second rotating member 82. In specific implementation, the first connecting member 81 is inserted and removed at the upper end of the lock core body 41. As the user's key gradually extends into the lock core body 41, until the key presses against the first connecting member 81 and presses the first connecting member 81 upward, the spring 83 is compressed and pushes the second rotating member 82 upward, thereby realizing the connection between the first connecting member 81 and the second rotating member 82. At this time, the key can be turned to mechanically unlock. When the user finishes unlocking, the key is gradually pulled out from the lock core body 41, and the external force applied by the compressed spring 83 disappears. At this time, the first connecting member 81 and the second rotating member 82 automatically descend and reset to their original positions, thereby restoring the separation state between the first connecting member 81 and the second rotating member 82. This structure is simple and practical, making it more convenient for users to use. The linkage mechanism 8 also includes a first limiting structure. After the key is inserted into the lock core body 41 , the first connecting member 81 can be pushed upward, and the second rotating member 82 can rotate with the lock core body 41 through the cooperation of the first limiting structure.

[0035] Continuing to refer to 1, 2, 7, and 8, specifically, the first position-limiting structure includes a first protrusion 811 disposed at the top of the first connecting member 81, a first crossbar 812 connected to the lower end of the first protrusion 811, and the first position-limiting structure also includes a first groove 821 correspondingly opened downward on the second rotating member 82 for the first protrusion 811 to be inserted into, and a slot 822 located at the lower end of the first groove 821 for the first crossbar 812 to be inserted into. Under normal conditions, the first connecting member 81 and the first rotating member 82 are always kept separated, that is, if the user inserts the key into the lock core body 41 without pressing the first connecting member 81 upward, the lock core body 41 and the first connecting member 81 can be driven to rotate, but the second rotating member 82 cannot be driven to rotate at this time. The rotation of the second rotating member 82 requires the user to push the first connecting member 81 upward by using the key until the first protrusion 811 at the upper end of the first connecting member 81 is inserted into the first groove 821, and the first cross bar 812 is inserted into the slot 822, so that the second rotating member 82 can be driven to rotate by the first connecting member 81. The matching arrangement of the first groove 821 and the first protrusion 811 facilitates the installation of the spring 83 between the first connecting member 81 and the second rotating member 82. The matching arrangement of the first cross bar 812 and the slot 822 facilitates circumferential positioning so that the first connecting member 81 drives the second rotating member 82 to rotate synchronously. It should be noted that the first protrusion 811 and the first cross bar 812 are both arranged on the first connecting member 81 and are integrally formed with the first connecting member 81 to ensure the stability of the first connecting member 81 and facilitate production and manufacturing; the first groove 821 and the slot 822 are both downwardly opened on the second rotating member 82 and are integrally formed with the second rotating member 82 to ensure the stability of the second rotating member 82 and facilitate production and manufacturing.

[0036] Furthermore, if Figure 7 As shown, a plurality of first teeth 71 are provided on the first rotating member 7, and a plurality of second teeth 823 which are convenient for meshing with the first teeth 71 are provided on the second rotating member 82, and the first rotating member 7 and the second rotating member 82 are meshed and connected. In specific implementation, the number of the first teeth 71 and the second teeth 82 can be set by the user according to the unlocking stroke of the motor and the mechanical lock core assembly. In specific implementation, in order to reduce the transmission stroke of the transmission structure of this case, the number of the first teeth 71 is set to three, and the number of the second teeth 823 is set to four because it needs to mesh with three first teeth 71. The first rotating member 7 and the second rotating member 82 are meshed and connected through the first teeth 71 and the second teeth 82. This gear transmission connection mode has relatively accurate transmission, high efficiency, compact structure, good stability and long service life. Of course, the user can also choose the connection mode of the first rotating member 7 and the second rotating member 82 to realize the transmission between the two, such as snap connection and plug connection.

[0037] like Figure 1 , Figure 4 , Figure 5 As shown, a recessed portion 11 cooperating with the locking mechanism 2 is provided on the lock beam 1. In specific implementation, the recessed portion 11 is symmetrically arranged on the two U-shaped legs of the "U"-shaped lock beam, and is relatively arranged on the inner side walls of the U-shaped legs. The locking mechanism 2 includes a rotating column 21 connected to the upper end of the first rotating member 7 and capable of rotating with the first rotating member 7, and a sphere 22 that can be partially accommodated in the recessed portion 11. The rotating column 21 includes a second crossbar 211 for sinking the sphere 22 into / out of the recessed portion 11 when the rotating column 21 rotates, and a second limiting structure is provided between the rotating column 21 and the first rotating member 7. Two recessed portions 11 are symmetrically arranged, and two spheres 22 are also symmetrically arranged accordingly, and the two spheres 22 are connected and fixed by a torsion spring 23, and the second crossbar 211 is arranged between the two spheres 22. That is to say, the torsion spring 23 is connected between the two balls 22. In the locked state, the second cross bar 211 applies force to press the balls 22 at both ends so that they sink into the recessed portion 11, and the torsion spring 23 is forced to open. When the user uses the motor 3 or the key to drive the mechanical lock core assembly 4 to unlock, the first rotating member 7 is driven to rotate so that the rotating column 21 rotates with the first rotating member 7, thereby causing the second cross bar 211 to rotate, and the force of the second cross bar 211 pressing on the balls 22 is released. Accordingly, the external force applied by the torsion spring 23 disappears, and the balls 22 at both ends are separated from the recessed portion 11 and gradually approach each other, thereby achieving unlocking. Arranging the balls 22 and the recessed portion 11 into two is more conducive to the cooperation between the lock beam and the locking mechanism 2, making it easier to lock / unlock, with better stability, more secure locking, and more convenient unlocking.

[0038] like Figure 1 , Figure 3 , Figure 4 , Figure 7 As shown, specifically, the second limiting structure includes a second groove 72 opened at the upper end of the first rotating member 7, and the rotating column 21 also includes a connecting end 212 arranged in the second groove 72. A limiting protrusion 73 for limiting the relative rotation angle between the first rotating member 7 and the rotating column 21 is arranged in the second groove 72. The second limiting structure is used to facilitate the first rotating member 7 to drive the rotating column 21 to rotate, while limiting the rotation angle of the rotating column 21 relative to the first rotating member 7. In specific implementation, the second groove 72 is opened at the center of the first rotating member, and the limiting protrusion 73 is arranged on the inner side wall of the second groove 72 opened by the first rotating member 7 and extends to its axis. One or two limiting protrusions 73 can be arranged in the groove 72 to limit the relative rotation angle between the first rotating member 7 and the rotating column 21, thereby limiting the unlocking angle. In this case, the limiting protrusion 73 is preferably symmetrically arranged as two, and the structure of the connecting end 211 is arranged to cooperate with the limiting protrusion 73 to achieve a rotation angle of ninety degrees, which is conducive to shortening the transmission stroke when opening and closing the lock, improving the transmission efficiency, enhancing the stability of the transmission structure, and reducing energy consumption.

[0039] Furthermore, if Figure 5-Figure 7 As shown, a reset mechanism 9 is provided on the rotating column 21 to automatically reset the rotating column 21. The reset mechanism 9 can automatically sink into the recessed portion 11 after the second cross bar 211 separates the ball 22 from the recessed portion 11. In specific implementation, the reset mechanism 9 can be a torsion spring arranged on the rotating member, and the other end of the torsion spring is fixed to the base 100. In practical applications, because the user usually does not know when to lock the fingerprint padlock after opening it, the reset mechanism 9 is set. When unlocking, the rotation of the rotating column 21 applies force to compress the reset mechanism 9. When the unlocking is completed, the external force applied to the rotating column 21 disappears. The reset mechanism 9 resets within a certain period of time to drive the rotating column 21 to rotate, so that the second cross bar 211 drives the ball 22 to automatically sink into the recessed portion 11 again, and the lock does not work at this time. The setting of the reset mechanism 9 in this case can reduce energy consumption, reduce the power consumption of the battery of the fingerprint padlock, and extend the service life of the transmission structure and the fingerprint padlock in this case.

[0040] like Figures 9 to 11 As shown, the present case also provides a fingerprint padlock, which includes a transmission structure of a fingerprint padlock described in the present case, and also includes a base 100, on which a mounting cavity 101 is provided, and the locking mechanism 2, the motor 3, and the mechanical lock core assembly 4 are all fixedly installed in the mounting cavity 101, and the lock beam 1 can be plugged and unplugged and set on the base 100, and a third limiting structure is also provided between the base 100 and the first rotating member 7. In specific implementation, the mounting cavity 101 is provided in the base 100 to provide installation space for the locking mechanism 2, the motor 3, the mechanical lock core assembly 4 and other components. The fixed arrangement means that the above-mentioned components are installed in the base 100 by means of snap-fit, plug-in, threaded connection, etc. on the inner side of the base 100, and then can be further connected and fixed by means of bolts, etc. This is a common installation method in the art and will not be repeated here. During specific implementation, one end of the U-shaped foot of the lock beam 1, specifically the fixed end, is elastically connected to the base 100 through a spring, and the fixed foot of the lock beam 1 is prevented from escaping from the base 100 through the limiting cooperation of the structure between the lock beam 1 and the base 100. The connection structure between the two can adopt a common structure in the field, which will not be repeated here.

[0041] like Fig. 9 The third limiting structure includes a fan-shaped groove 74 provided on the outer periphery of the first rotating member 7, a limiting block 102 provided on the base 100, and blocking parts 75 are provided at both ends of the fan-shaped groove 74. When the first rotating member 7 rotates, the limiting block 102 is limited to slide between the two blocking parts 75. The third limiting structure is provided to limit the rotation angle of the first rotating member 7. In specific implementation, it is preferred that the third limiting structure is provided to make the first rotating member 7 rotate at a 90-degree limiting structure. In this way, it is beneficial to shorten the transmission stroke when opening and closing the lock, improve the transmission efficiency, enhance the stability of the transmission structure, and reduce energy consumption.

[0042] Furthermore, the fingerprint padlock of the present case also includes a battery 200 and a fingerprint recognition module 300 installed in the base 100, and also includes a front plate 400 covering the base 100. The fingerprint recognition module 300 includes a fingerprint collection panel 301. The front plate 400 is provided with a first protective cover 401 that can be slid open / closed to cover the fingerprint collection panel 301. The lower end of the base 100 is provided with a second protective cover 103 that can be opened / closed. The setting of the first protective cover 401 facilitates the user to expose the fingerprint collection panel 301 to the front plate 400 by sliding unlocking, so as to facilitate the user to use fingerprint unlocking. This sliding connection method is relatively convenient and easy to use. On the other hand, the first protective cover 401 can effectively protect the fingerprint collection panel 301, and can effectively prevent liquid or other foreign matter from entering the interior of the fingerprint padlock, which is good for the safety of the fingerprint padlock. In specific implementation, a charging interface for charging the battery 200 is provided at the bottom of the base 100, and the keyhole of the charging interface machine mechanical lock core assembly 4 is exposed at the bottom of the base 100. The user can see the charging interface and the keyhole by opening the second protective cover 103. In specific implementation, the second protective cover 103 can be connected to the base 100 by common riveting, such as hinge connection, etc., to facilitate the opening and closing of the second protective cover 103 relative to the base 100. The other end of the second protective cover 103 can be snapped onto the base 100, further facilitating the opening and closing of the second protective cover 103 relative to the base 100. The setting of the second protective cover 103 facilitates the user to open the protective cover to charge the fingerprint padlock and use the key to unlock the lock, while effectively protecting the keyhole and charging hole of the fingerprint padlock to prevent liquid or other foreign matter from entering the fingerprint padlock and damaging the fingerprint padlock. In specific implementation, the fingerprint recognition module 300 is also installed in the base 100 and is located above the battery. Furthermore, the front plate 400 is provided to connect and fix the battery 200 and other components of the fingerprint collection module 300. When the front plate 400 is covered on the base 100, the locking mechanism 2, the motor 3, and the mechanical lock core assembly 4 can be completely covered. Then the front plate 400 is connected and fixed to the base 100 by means of plugging, bolts, etc., and finally connected and reinforced, which is conducive to the stability of the installation and connection between the components, and further stabilizes the installation of the locking mechanism 2, the motor 3, and the mechanical lock core assembly 4. The fingerprint padlock in this case has a simple structure and few parts. The way the parts are installed and arranged is conducive to saving installation space, so as to reduce the overall volume of the fingerprint padlock, and facilitate transportation, carrying and use.

[0043] As mentioned above, this case protects a transmission structure of a fingerprint padlock and a fingerprint padlock. All technical solutions that are the same or similar to this case should be deemed to fall within the protection scope of this case.
