Description

Technical Field

[0001] This utility model relates to the field of lock-related technology, and in particular to a fingerprint lock and security lock for bags. Background Technology

[0002] Luggage is widely used for carrying personal belongings during travel and daily outings. To ensure the safety of these valuables, most luggage on the market is equipped with combination locks. These traditional combination locks rely on numerical combinations for authentication, but their combination length is limited, their mechanical structure is relatively simple, and they are easily cracked by combination attempts, eavesdropping, or tactile vibration techniques. Their security and reliability are insufficient to meet users' needs for safeguarding important items. To improve security, fingerprint locks using biometric technology are increasingly being applied to luggage products. Fingerprint recognition uses the inherent biometric characteristics of the human body as a key, offering advantages such as uniqueness and difficulty in duplication. This makes them significantly more reliable than traditional combination locks in terms of authentication reliability, while also avoiding the inconvenience of remembering passwords or carrying physical keys. However, existing fingerprint locks for luggage still have significant technological shortcomings. To achieve fingerprint recognition, verification, and bolt activation functions, their internal lock body structure is complex and their overall size is relatively large, affecting the portability of the luggage.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Reference Figures 1 to 5 According to a first aspect of the present invention, a fingerprint lock for bags includes a housing 100, a fingerprint recognition module 200, a drive motor 300, and a latch 500. The fingerprint recognition module 200 is disposed in the housing 100, and the drive motor 300 is disposed in the housing 100 and electrically connected to the fingerprint recognition module 200. The output shaft of the drive motor 300 is provided with a transmission component 400. The latch 500 is slidably connected to the housing 100 and can slide to a locked position and an unlocked position. The side wall of the latch 500 is provided with a protruding transmission pin 510, and the transmission component 400 is provided with a spiral transmission part. The spiral transmission part is connected to the transmission pin 510 to drive the latch 500 to slide. The fingerprint recognition module 200 can control the drive motor 300 to run according to the recognition signal to drive the latch 500 to slide to the locked position or the unlocked position. The fingerprint recognition module 200 can drive the drive motor 300 according to the recognition signal. The drive motor 300 can have a transmission component 400 directly installed at the output shaft. The drive motor 300 drives the transmission component 400 to rotate and drives the spiral transmission part to rotate. The spiral transmission part cooperates with the transmission pin 510 of the lock tongue 500 and can drive the lock tongue 500 to slide to the locked position or the unlocked position. This simplifies the transmission structure, requires fewer parts, and makes the lock body structure compact.

[0023] Specifically, the housing 100 can be installed on a bag. The fingerprint recognition module 200 may include a control circuit board, a battery, and a fingerprint sensor. The fingerprint sensor may be located on the outer surface of the housing 100 for user pressing. The control circuit board and battery are located inside the housing 100. The control circuit board can be electrically connected to the drive motor 300. The control circuit board can determine the action of the drive motor 300 based on the signal from the fingerprint sensor. The specific control process described above will not be described in detail here. The output shaft of the drive motor 300 is provided with a transmission component 400. The transmission component 400 may also be an integral structure with the output shaft. The transmission component 400 can be directly driven to rotate by the drive motor 300. The helical transmission part on the transmission component 400 may be a helical groove or helical surface spirally arranged around the output shaft of the drive motor 300. The transmission pin 510 can abut against the helical transmission part for transmission. When the transmission component 400 rotates, the transmission pin 510 can be directly driven to slide up and down through the helical transmission part. The locking tongue 500 can slide upward to the locked position or downward to the unlocked position. Understandably, when the latch 500 slides to the locked position, it engages with the zipper of the bag to lock it; when it slides to the unlocked position, the zipper can be pulled freely to unlock it. In existing technology, the motor output shaft of the lock body generally has an eccentric shaft, and there is also an intermediate transmission structure between the eccentric shaft and the latch 500, making the structure relatively complex. In this application, the drive motor 300 can directly drive the latch 500 through a helical transmission part, which simplifies the structure, reduces the number of parts, and makes the lock body structure more compact.

[0024] Reference Figures 2 to 3 In some embodiments of this utility model, an elastic element 520 is provided between the latch 500 and the housing 100. The elastic element 520 can drive the latch 500 to slide towards the locking position. The helical transmission part includes a first helical transmission surface 411, and the side of the transmission pin 510 near the locking position abuts against the first helical transmission surface 411. Specifically, the elastic element 520 can be a spring, with one end abutting against the housing 100 and the other end abutting against the latch 500, and can drive the latch 500 to slide to the locking position. By providing the elastic element 520, the first helical transmission surface 411 only needs to abut against one side of the transmission pin 510 for transmission, which simplifies the transmission structure and eliminates the need for a helical groove. When the first helical transmission surface 411 rotates, it can drive the latch 500 to slide downward to the unlocking position and simultaneously compress the elastic element 520. When locked, the first helical transmission surface 411 returns to its original position, and the elastic element 520 can drive the latch 500 to reset to the locking position.

[0025] Reference Figures 4 to 5In some embodiments of this utility model, the transmission component 400 includes a cylindrical main body 410, which is coaxially arranged with the output shaft of the drive motor 300. A first helical transmission surface 411 is provided on the bottom surface of the main body 410. Specifically, the rotation axis of the cylindrical main body 410 coincides with the output shaft of the drive motor 300, which can reduce the space occupied in the radial direction and make the structure more compact. The bottom surface of the cylindrical main body 410 can be cut around the output shaft of the drive motor 300 to form the first helical transmission surface 411. The transmission pin 510 can extend into the main body 410 and abut against the first helical transmission surface 411 for transmission.

[0026] Reference Figures 4 to 5 In some embodiments of this utility model, a positioning post 420 is provided at the top of the main body 410. The positioning post 420 is coaxially arranged with the main body 410 and is rotatably connected to the housing 100. Specifically, the positioning post 420 can rotate with the housing 100 and form a support point, which enables the main body 410 to rotate stably and makes the transmission process more stable.

[0027] Reference Figures 1 to 3 In some embodiments of this utility model, the housing 100 is rectangular, the sliding direction of the latch 500 is parallel to the length direction of the housing 100, and the latch 500 and the drive motor 300 are arranged side by side along the width direction of the housing 100, with the length direction of the drive motor 300 parallel to the length direction of the housing 100. Specifically, the extension direction of the drive motor 300 matches the length direction of the housing 100, and the sliding direction of the latch 500 also matches the length direction of the housing 100. This fully utilizes the space along the length direction of the housing 100, reducing the width of the housing 100 and making the overall lock structure more compact.

[0028] Reference Figure 2 In some embodiments of this utility model, the fingerprint recognition module 200 is located on the side of the drive motor 300 near the bolt 500, and the fingerprint recognition module 200 is located below the bolt 500. Specifically, the bolt 500 is relatively short, and the top of the drive motor 300 is driven and engaged with the bolt 500 through the transmission component 400, so that there is space below the bolt 500, and the fingerprint recognition module 200 can be placed in this space, which can make full use of the internal space of the housing 100, thereby making the overall structure of the lock body more compact.

[0029] Reference Figure 2In some embodiments of this utility model, the fingerprint recognition module 200 also has a charging interface 210, and the housing 100 is also provided with a through hole 110 to avoid the charging interface 210. The through hole 110 is provided with a cover 120, which can block the through hole 110. Specifically, the charging interface 210 can charge the battery, the through hole 110 allows the charging interface 210 to be exposed for the plug to be inserted, and the cover 120 can be made of soft rubber material. The cover 120 can block the through hole 110 to protect the charging interface 210.

[0030] Reference Figures 2 to 3 In some embodiments of this utility model, the housing 100 is further provided with a locking hole 130 for inserting the locking pin 600. In the locked position, the locking tongue 500 can be inserted into the locking hole 130 and locked with the locking pin 600. It can be understood that the locking tongue 500 can be inserted from the side wall of the locking hole 130. After the locking pin 600 is inserted into the locking hole 130, the locking pin 600 can be provided with a locking hole that cooperates with the locking tongue 500. The locking tongue 500 can restrict the locking pin 600 from being pulled out along the direction of the locking pin 600 hole to achieve locking.

[0031] It should be noted that the latch 500 may be provided with a guide ramp. The guide ramp is located on the side of the latch 500 near the locking pin 600 and slopes downwards and upwards towards the direction away from the locking pin 600. The elastic element 520 drives the latch 500 to remain inserted into the locking hole 130. When the locking pin 600 is inserted into the locking hole 130, the guide ramp can drive the latch 500 to retract and compress the elastic element 520. When the locking pin 600 is fully inserted, the latch 500 can be inserted into the locking hole of the locking pin 600 through the elastic element 520. At this time, the locking pin 600 cannot be pulled out, thus achieving locking. The above structure facilitates the locking of the locking pin 600 of the bag.

[0032] Reference Figure 5 In some embodiments of this utility model, the helical transmission part further includes a second helical transmission surface. The second helical transmission surface is disposed on the bottom surface of the main body 410 and connected to the first helical transmission surface 411. The helical directions of the first helical transmission surface 411 and the second helical transmission surface are opposite. Specifically, the first helical transmission surface 411 can be set at an angle of less than 180°, while the second helical surface 412 can be symmetrically arranged with the first helical surface, so that the drive motor 300 can adjust its rotation direction and selectively use the second helical surface 412 for transmission.

[0033] According to a second aspect embodiment of the present invention, a security bag includes a security bag employing the aforementioned fingerprint lock for a bag. By employing the aforementioned fingerprint lock for a bag, the fingerprint lock structure can be simple and compact, with low manufacturing cost and small space occupation, so that the portability of the security bag is not affected.
