Description

Technical Field

[0001] The utility model relates to the field of electronic locks for luggage, in particular to a fingerprint electronic lock with a compact internal structure, which is suitable for luggage and boxes with aluminum alloy frames. Background Art

[0002] When people travel, they often carry their clothing and other belongings in luggage, making the convenience of luggage increasingly important. Luggage on the market is generally categorized as soft-shell or hard-shell. Soft-shell luggage typically uses a combination of fabric and plastic for the outer shell, with the two halves connected by a zipper. Hard-shell luggage typically has two halves connected by an aluminum alloy frame. The two halves lock together with a lock. Hard-shell luggage is typically made of PC, ABS, PP, or aluminum alloy.

[0003] Many existing hard-shell luggage and bags, after entering the high-end market, have adopted automatic unlocking with fingerprint electronic locks, making them increasingly convenient to use. The general principle of a fingerprint electronic lock for luggage and bags is that a fingerprint driver drives a motor, which in turn drives the internal mechanism of the lock body to unlock. When the motor resets, the internal mechanism of the lock body resets due to the action of a spring. Of course, a power module is also provided to provide power to the fingerprint electronic lock.

[0004] Luggage fingerprint electronic locks typically consist of a fingerprint driver module and a lock body, meaning they comprise at least two parts. If two lock bodies are used, the total number of parts is three. The fingerprint driver module typically houses the fingerprint module and a mainboard, while the lock body includes a lock box and a lock catch. The lock box typically houses a lock hook mechanism and a motor that drives the lock hook mechanism. Existing fingerprint electronic locks for luggage either have the fingerprint driver module and lock body completely separate, with the fingerprint driver module and lock body electrically connected via wires, or simply have the outer casing connected via a connector, while the fingerprint driver module and lock body themselves remain separate.

[0005] Therefore, the inventors hope to integrate the fingerprint driver module and the lock body to reduce the overall size of the luggage fingerprint electronic lock. However, the integrated unit cannot be too large, because if the unit is too large, it will be difficult to fit the electronic lock mounting position on the luggage, which generally has a specific size range.

[0006] This brings great difficulty to the integration of the luggage fingerprint electronic lock, so the inventor redesigned the internal structure of the luggage fingerprint electronic lock, thereby obtaining the luggage fingerprint electronic lock with a compact internal structure of the present invention.

[0045] Example:

[0046] like Figures 1 to 13 The figure shows a fingerprint electronic lock for aluminum alloy frame cases with a compact internal structure. The lock comprises a main body, which includes a base portion secured to the case and a locking portion hingedly connected to the base portion. The locking portion of the main body integrates a fingerprint module 2, a mainboard 4, a first locking hook mechanism, and a first motor 5. The integrated internal structure is compact, making the overall size of the fingerprint electronic lock smaller. Of course, the fingerprint electronic lock for cases in this embodiment also includes a power module 15 and a lock buckle 13. The power module 15 provides power to the fingerprint electronic lock, and the lock buckle 13 is used to engage the lock hook of the first locking hook mechanism for locking.

[0047] Specifically: the first lock hook mechanism includes a cam 6, a moving block 7 and a return spring 18, and the locking part includes a panel 1 and a bottom plate 9. Figures 1 to 3 As shown, the inner side of the panel 1 is provided with a mainboard mounting position 1.5, a motor mounting slot 1.6, and a slide slot 1.7. The mainboard 4 is configured in a U-shape, forming a U-shaped notch 4.3. The mainboard 4 is installed in the mainboard mounting position 1.5 and secured with screws. Once fixed, the mainboard 4 is positioned against one end of the panel 1, with the centerline of the mainboard 1 aligning with the centerline of the panel 4. The motor mounting slot 1.6 is positioned within the U-shaped notch 4.3 of the mainboard 4. The first motor 5 is correspondingly mounted in the motor mounting slot 1.6, so that the first motor 5 is located within the U-shaped notch 4.3 of the mainboard 4. The slide slot 1.7 is provided near the other end of the panel 1, and a movable block 7 is positioned within the slide slot 1.7, allowing the movable block 7 to slide back and forth.

[0048] like Figure 10As shown, cam 6 is cylindrical in shape and mounted on the output shaft of first motor 5. Cam 6 is driven by first motor 5 for rotation. A spiral portion 6.1 is provided on the sidewall of cam 6. A sleeve 7.4 is provided at the rear end of movable block 7. A slider 7.5 is located within sleeve 7.4. Sleeve 7.4 fits over cam 6, and slider 7.5 slides over spiral portion 6.1. A stop post 7.3 is provided in front of movable block 7. One end of a return spring 18 fits over stop post 7.3, while the other end abuts against the inner side of panel 1. Return spring 18 provides a rearward restoring force for movable block 7. The movable block 7 is provided with a lock hook 7.1, which is used to cooperate with the hook on the lock hole 13.1 of the lock buckle 13. A lock hole 9.1 is provided on the base plate 9 corresponding to the lock hook 7.1. The side of the lock hook 7.1 close to the lock hole 9.1 is a slope 7.6. The slope 7.6 allows the lock buckle 13 to pass through the lock hole 9.1 and push the movable block 7 forward through the slope 7.6 so that the lock buckle 13 can be buckled in.

[0049] Panel 1 has a first opening 1.2 positioned adjacent to one end of panel 1, corresponding to mainboard mounting position 1.5. Fingerprint module 2 is fixedly mounted on the inner surface of panel 1, corresponding to first opening 1.2. The fingerprint input surface of module 2 is exposed through first opening 1.2, thereby securing module 2 between mainboard 4 and the front face of the locking portion. Fingerprint module 2 is secured by a first pressure member 3, which presses against the back of module 2 and is fixedly connected to the inner surface of panel 1 via screws.

[0050] from Figure 1 It can be seen that, through the arrangement of the above structure, the positions between the main board 4, the first locking hook mechanism, the first motor 5 and the fingerprint module 2 are very compact, which fully fills the internal space of the panel 1, thereby making the overall volume smaller.

[0051] The fingerprint module 2 is electrically connected to the mainboard 4. During use, fingerprints are recorded through the fingerprint module 2, or the fingerprint electronic lock of a luggage is unlocked.

[0052] In this embodiment, a fingerprint registration button 4.1 is further provided on the main board 4 for controlling fingerprint registration and clearing. A corresponding button hole 9.2 is provided on the bottom plate 9, through which the fingerprint registration button 4.1 emerges. When the luggage electronic fingerprint lock is locked, the fingerprint registration button 4.1 is located on the inner side of the lock and does not appear on the outer surface. This prevents outsiders from operating the fingerprint registration button 4.1 after the lock is locked, ensuring safe use. Subsequently, during use, a single press of the fingerprint registration button 4.1 causes the fingerprint module 2 to enter the fingerprint registration state, at which point fingerprint registration can be performed. Pressing the fingerprint registration button 4.1 for longer than a set time clears the internal fingerprint information. This demonstrates that the provision of the fingerprint registration button 4.1 makes fingerprint registration and clearing operations more convenient and faster.

[0053] In this embodiment, a mechanical lock cylinder 8 is integrated into the locking portion of the main box. The mechanical lock cylinder 8 is a conventional lock cylinder, which is commonly used in existing electronic locks. A lock cylinder mounting hole 1.8 is provided on the inner side of the panel 1, and a third opening 1.4 is provided on the front of the panel 1 corresponding to the lock cylinder mounting hole 1.8. The mechanical lock cylinder 8 is embedded and fixed in the lock cylinder mounting hole 1.8, with the front end exposed from the third opening 1.4. A protrusion 8.1 is provided at the bottom of the mechanical lock cylinder 8, and a blocking rod 7.2 is provided on the movable block 7. Figure 9 As shown, the protrusion 8.1 is located behind the blocking rod 7.2. When the mechanical lock core 8 rotates to unlock, it will drive the protrusion 8.1 to rotate, and then push the blocking rod 7.2 through the protrusion 8.1, so that the moving block 7 moves forward to complete the unlocking.

[0054] The base of the main case includes a rear bottom shell 14 and a seat plate 12. During installation, the rear bottom shell 14 and seat plate 12 are positioned on the inside and outside of the case, respectively, and then bolted together to secure the base to the case. The end of the locking portion of the main case, away from the hook 7.1, is hingedly connected to the seat plate 12. The hinged connection is structured as follows: hinge slots 1.1 are provided on either side of the bottom of the panel 1, away from the hook 7.1. Connecting pins 17 are located within the hinge slots 1.1. Hinge ears 12.1 are provided on either side of the seat plate 12. These ears extend into the hinge slots 1.1, and the connecting pins 17 extend through hinge holes 12.2 in the ears 12.1.

[0055] In this embodiment, two unlocking springs 27 are provided between the seat plate 12 and the bottom plate 9. Spring mounting posts 12.3 are provided on both sides of the upper side of the seat plate 12, and spring mounting holes 9.3 are provided on both sides of the bottom plate 9. One end of the unlocking spring 27 is sleeved on the spring mounting post 12.3, and the other end is embedded in the spring mounting hole 9.3. When unlocking, the unlocking spring 27 automatically pops up the locking part.

[0056] The power module 15 of this embodiment is detachable and movable, and is shaped like a USB flash drive. It is equipped with a battery and a charge and discharge control circuit board. A USB plug 15.2 is provided at one end of the connection. The battery and the USB plug 15.2 are electrically connected to the charge and discharge control circuit board respectively. Figure 12 As shown, the rear bottom case 14 is provided with a power supply mounting slot 14.2. One end of the power supply mounting slot 14.2 is open, and the other end is provided with a first USB female connector 11.1. A latch 14.3 is provided on the side of the opening of the power supply mounting slot 14.2. A latch block 15.1 is provided on the side of the end of the power module 15 away from the USB plug 15.2. The power module 15 can be inserted into the power supply mounting slot 14.2, and the latch block 15.1 is engaged with the latch 14.3. The USB plug 15.2 is then inserted into the first USB female connector 11.1, completing the electrical connection.

[0057] This embodiment includes an interface board 11, a first USB female connector 11.1 disposed on the interface board 11, and an interface board mounting slot 14.1 disposed within the rear bottom housing 14. Interface board mounting slot 14.1 is located adjacent to the end of the power supply mounting slot 14.2, distal from the opening. Interface board 11 is mounted within interface board mounting slot 14.1. A second pressure member 10 covers the notch of interface board mounting slot 14.1 and is secured with screws. A through hole is provided on the end surface of the power supply mounting slot 14.2, corresponding to the first USB female connector 11.1, allowing the first USB female connector to be exposed within the power supply mounting slot 14.2.

[0058] In this embodiment, a second USB female connector 4.2 is provided on the mainboard 4, corresponding to a second opening 1.3 on the front panel 1. The second USB female connector 4.2 is exposed through the second opening 1.3. The second USB female connector 4.2 can also connect to the USB plug 15.2 of the power module 15. During use, the power module 15 can be removed from the power supply mounting slot 14.2 and then inserted into the second USB female connector 4.2 to power the luggage fingerprint electronic lock. This embodiment also includes a removable rubber plug 16 covering the second opening 1.3.

[0059] The first USB female socket 11.1, the second USB female socket 4.2, and the USB plug 15.2 of this embodiment adopt a matching standard Type-C interface structure. In other embodiments, other USB interface structures may also be adopted.

[0060] like Figures 14 to 17The luggage shown in this embodiment includes a first half-case 21, a second half-case 22, and the aforementioned fingerprint electronic lock for luggage, with only one lock installed. The first and second half-cases 21, 22 are surrounded by an aluminum alloy frame. The aluminum alloy frames on one side of the first and second half-cases 21, 22 are hinged together, and the middle of each side is provided with an inwardly recessed electronic lock mounting position 23. The main body of the fingerprint electronic lock for luggage is installed in the electronic lock mounting position 23 of the first half-case 21. The specific installation structure is as follows: a mounting hole is opened in the electronic lock mounting position 23 of the first half-case 21. The rear bottom shell 14 is positioned on the inner side of the first half-case 21, and the base plate 12 is positioned on the outer side of the first half-case 21. The lock is then fixedly connected by screws, thereby being fixed in the recess of the first half-case. The lock catch 13 is installed in the electronic lock mounting position 23 of the second half-case 22.

[0061] The specific usage process of this embodiment is as follows:

[0062] When the bag needs to be locked, the first half box body 21 and the second half box body 22 are closed, and then the locking part of the main box body is rotated so that the lock buckle 13 is inserted into the lock hole 9.1 accordingly. At this time, the unlocking spring 27 will be compressed. During the insertion process, the lock buckle 13 is pressed against the inclined surface 7.6, and the movable block 7 is pushed by the inclined surface 7.6, so that the lock hook 7.1 is avoided to one end. When the lock buckle 13 is fully inserted, the movable block 7 will be reset under the action of the reset spring 18, so that the lock hook 7.1 is inserted into the lock buckle hole 13.1 of the lock buckle 13 accordingly, completing the locking of the lock buckle 13 and achieving locking.

[0063] When the bag needs to be unlocked, a correct fingerprint is input into the fingerprint module 2. The mainboard 4 then controls the first motor 5 to rotate, which in turn drives the cam 6. The spiral portion 6.1 of the cam 6 pushes the movable block 7 forward, causing the lock hook 7.1 to exit the lock hole 13.1 of the lock buckle 13, completing the unlocking process. At this point, the unlocking spring 27 automatically causes the locked portion to flip outward, allowing the first half 21 and the second half 22 to be opened. After the unlocking time has passed, the first motor 5 automatically rotates in the opposite direction, and the movable block 7 is reset by the reset spring 18.

[0064] To unlock the bag, you can also use a key to unlock it. Insert the correct key into the mechanical lock cylinder 8 and then rotate it, so that the protrusion 8.1 pushes the blocking rod 7.2, and then pushes the moving block 7 forward, so that the lock hook 7.1 withdraws from the lock hole 13.1 of the lock buckle 13, completing the unlocking.

[0065] Among them, the use of the power module 15 of this embodiment is very flexible: the power module 15 can be installed in the power installation slot 14.2 and connected to the first USB female socket 11.1 to power the luggage fingerprint electronic lock, or it can be taken out of the power installation slot 14.2 and inserted into the second USB female socket 4.2 to power the luggage fingerprint electronic lock. Figure 15 The figure shows a schematic diagram of the structure in which the power module 15 is plugged into the second USB female socket 4.2. When charging is required, the power module 15 can be directly taken out and plugged into an external charging head for charging. One convenient use scenario of the power module 15 is that when a user needs to take a plane with luggage, the power module 15 can be conveniently taken out from the power installation slot 14.2 and carried by the user, while the luggage can be checked in. After getting off the plane, when the luggage is retrieved, the power module 15 is plugged into the second USB female socket 4.2 to power the luggage fingerprint electronic lock, and the luggage can be easily unlocked again without mechanical unlocking.

[0066] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto.
