Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0034] This utility model provides a fingerprint padlock, including: an outer shell 2, an inner liner 3, a lock beam 1, and connecting parts (not shown in the figure, but may be screws, bolts, etc.); the outer shell 2 is integrally formed and fits over the inner liner 3. The bottom of the outer shell 2 is open to facilitate fitting onto the inner liner 3 from the top. The top of the outer shell 2 is provided with a first insertion hole 5 and a second insertion hole 6. The bottom of the inner liner 3 is provided with a fingerprint receiving module 7. The open bottom of the outer shell 2 also allows the user to press the fingerprint receiving module 7. The top of the inner liner 3 or the outer shell 2 is provided with a first insertion channel 23 extending from the top to the bottom; the top of the outer shell 2 or the inner liner 3 is provided with a second insertion channel 24 extending from the top to the bottom. The first insertion hole 5 is located at the top of the first insertion channel 23 and is interconnected with it. The second insertion hole 6 is located at the top of the second insertion channel 24 and is connected to it. The second insertion channel 24 and the first insertion channel 23 are for the two ends of the locking beam 1 to be inserted. The inner liner 3 can lock and unlock the locking beam 1 when it is inserted. When unlocked, at least the end of the locking beam 1 located in the second insertion channel 24 can be moved out of the second insertion channel 24. A connecting base plate 27 is provided at the bottom of the second insertion channel 24. The connecting base plate 27 is fixedly connected to the outer shell 2. A connecting hole 26 is provided on the connecting base plate 27. A fixing hole 25 is provided on the inner liner 3 below the connecting hole 26, which is directly opposite to the connecting hole 26. The connector can extend from the top of the connecting hole 26 into the fixing hole 25 and press the connecting base plate 27 and the inner liner 3 together.

[0035] The fingerprint padlock provided by this utility model has a waterproof outer shell 2, which is a one-piece structure without any extra assembly structures. This greatly improves the sealing performance of the outer shell 2. In addition, the structure for connecting the outer shell 2 to the inner shell 3 is located inside the second insertion channel 24. The connection structure adopts a concealed design, which further improves the sealing performance. Moreover, in the locked state, the outer shell 2 cannot be removed from the outside by damaging the connection structure, thus improving the security of the fingerprint padlock. This utility model solves the problem of insufficient protection for important components in existing fingerprint padlocks, which makes it easy for water to seep into the interior from the external structural parts.

[0036] Furthermore, the fingerprint receiving module 7 in this application is located at the bottom of the inner liner 3. When the padlock is in use, it is suspended under its own weight. When the padlock is exposed to water, it is difficult for water to wet the fingerprint receiving module 7 from the bottom up, and it is also difficult for water to enter the inner liner 3 through the installation gap. Therefore, the fingerprint receiving module 7 is located at the bottom of the inner liner 3, which further improves the waterproof effect.

[0037] like Figure 1 and Figure 11 The two styles of outer shell 2 shown are provided by this utility model. The outer shell 2 and inner liner 3 are detachable. The inner liner 3 can be freely matched with different styles of outer shell 2, which increases the appearance of the product and makes it easier for users to choose freely.

[0038] In some embodiments, the bottom structure of the inner liner 3 and the open structure at the bottom of the outer shell 2 are matched in shape and size, thereby making the overall appearance of the padlock aesthetically pleasing and without any abrupt structures.

[0039] In some embodiments, such as Figure 8 As shown, the bottom of the inner liner 3 is provided with a keyhole 19 for inserting a key. Specifically, the keyhole 19 is located at the bottom of the key-opening lock cylinder 8. Furthermore, the bottom of the inner liner in this application is provided with multiple structures communicating with the interior of the inner liner. Figure 8 The diagram shows four structures, all located at the bottom of the padlock. These structures also serve a waterproof function. Specifically, when the padlock is exposed to water, water is less likely to enter the lock through the bottom structure. This differs from existing designs that place these structures on the side or top. When these structures are placed on the side or top, water can easily accumulate in the structure when the padlock is exposed to water, and the assembly gaps can allow water to enter the padlock, potentially damaging internal components.

[0040] This embodiment provides an alternative unlocking solution that allows users to unlock the door with a key, thus avoiding the drawback of the fingerprint padlock being unable to open when the power is off.

[0041] In some embodiments, the connector is a screw or bolt, and the fixing hole 25 is a threaded hole.

[0042] The screws or bolts used in this embodiment are common fasteners that are low in cost and provide reliable connections.

[0043] In some embodiments, the execution module can simultaneously lock both ends of the locking beam 1 inserted into the first insertion channel 23 and the second insertion channel 24.

[0044] This embodiment improves stability in the locked state, thereby enhancing security during use.

[0045] In some embodiments, in the unlocked state, only the end of the locking beam 1 located within the second insertion channel 24 can move out of the second insertion channel 24.

[0046] In this embodiment, after the padlock is assembled, the end of the lock beam 1 located in the first insertion channel 23 is always located in the channel, whether in the unlocked or locked state.

[0047] In some embodiments, the inner liner 3 is provided with an information processing module 10 and an execution module. The fingerprint receiving module 7 is used to receive fingerprint information and transmit it to the information processing module 10. The information processing module 10 is used to process and judge the fingerprint information, and control the execution module to perform the unlocking action when the fingerprint information is correct.

[0048] This embodiment provides a specific unlocking logic. When the user needs to unlock the device, the user can press the corresponding finger on the fingerprint receiving module 7. After the fingerprint receiving module 7 records the fingerprint information, it is transmitted to the information processing module 10. The information processing module 10 compares the recorded fingerprint information with the standard fingerprint information. When the comparison results are the same, the information processing module 10 controls the execution module to perform the unlocking action.

[0049] The execution module includes a motor 11, a reducer, a motor dial 12, an unlocking dial 13, a cam 15, a ball bearing 14, and a locking groove 18.

[0050] Specifically, the motor 11 increases the torque through the reducer and inputs the torque to the motor dial 12. The motor dial 12 drives the unlocking dial 13 to rotate, and the unlocking dial 13 drives the cam 15 to rotate synchronously. The cam 15 is provided with a groove. When the groove on the cam 15 rotates to face the ball 14, the ball 14 can roll freely into the groove and unlock. After unlocking, the cam 15 has a tendency to twist under the action of the torsion spring. However, the ball 14 on one side is restricted by the outer wall of one end of the lock beam 1, which prevents the cam 15 from twisting back to its original position. This allows the padlock in the unlocked state to lock at any time by pressing down the lock beam 1 so that the other end of the lock beam 1 can be inserted into the second insertion channel 24. When locking, since the lock slots 18 on both sides of the lock beam 1 are at the same height, when they move down synchronously to face the ball 14 on both sides, the ball 14 on both sides can enter the lock slot 18. At this time, under the action of the torsion spring, the cam 15 automatically twists and returns to the locked state.

[0051] Of course, the above is only one principle of unlocking and locking. In some examples, this utility model can use any lock cylinder structure in the prior art to achieve unlocking and locking.

[0052] In some embodiments, the connecting base plate 27 is integrally formed with the outer shell 2.

[0053] This embodiment provides a connection method for connecting the base plate 27 and the outer shell 2.

[0054] In some embodiments, the second insertion channel 24 is formed on the housing.

[0055] In some embodiments, a mounting opening is provided on one side of the first insertion channel 23, and a return spring 20 is provided inside the first insertion channel 23. One end of the locking beam 1 is inserted into the first insertion channel 23 and the return spring 20. The end of the locking beam 1 inserted into the return spring 20 is provided with a flange 17 extending radially outward. The portion of the locking beam 1 inserted into the first insertion channel 23 is provided with an annular limiting surface extending radially. A limiting part 21 is provided inside the first insertion channel 23. The limiting part 21 is located between the annular limiting surface and the flange 17. When locking, the limiting part 21 and the annular limiting surface cooperate to restrict the locking beam 1 from moving excessively downward. When unlocking, the limiting part 21 and the flange 17 cooperate to restrict the locking beam 1 from moving excessively upward.

[0056] This embodiment provides a specific method for restricting the end of the locking beam 1 located within the first insertion channel 23 from moving out of the channel.

[0057] In some embodiments, the present invention further includes a positioning block 4, and the limiting part 21 is formed by the top structure of the positioning block 4. A slide 22 extending from the assembly opening away from the assembly opening is provided on the first insertion channel 23. Part of the edge of the positioning block 4 can slide into the slide 22 from the top of the slide 22. The positioning block 4 that slides into the first insertion channel 23 can be abutted by the inner wall of the outer shell 2 on one side of the inner liner 3 to restrict the positioning block 4 from moving out of the first insertion channel 23.

[0058] In this embodiment, the positioning block 4 is detachable, which facilitates maintenance and assembly during the initial manufacturing process.

[0059] In some embodiments, for ease of assembly, the top of the inner liner of this invention has an open groove structure for installing ball bearings and cams. After the ball bearings and cams are installed, they are limited by the top baffle 16 to prevent the ball bearings 14 from coming out. In addition, the side of the inner liner 3 also has an open groove structure. After the motor 11, circuit board (i.e., the aforementioned information processing module 10), battery 9 and other structures are installed inside, the side is closed and covered by a detachable cover plate.

[0060] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
