DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] The following references Figures 1-6 The present application is described as follows:

[0037] Embodiment: A luggage fingerprint lock, comprising a shell 1, the bottom of the shell 1 is provided with an opening, and the bottom of the shell 1 is connected with a bottom cover plate. This structure not only facilitates the installation and maintenance of internal components, but also ensures the overall sealing and stability.

[0038] The shell 1 is provided with a movable long strip-shaped lock tongue 2, which is used as a component directly performing a locking action and can be flexibly moved in the shell.

[0039] The shell 1 is also provided with a motor 3, a fingerprint assembly 4 and a battery 5, the battery 5 and the motor 3 are connected with the fingerprint assembly 4 respectively; the battery 5 supplies power to the motor 3 and the fingerprint assembly 4, and the motor 3 is started after correct fingerprint information is input into the fingerprint assembly 4.

[0040] The motor 3 is used as a power source to provide driving force for an unlocking action; the fingerprint assembly 4 undertakes the task of identifying the identity of a user and is a key "gatekeeper" for unlocking the bag; the battery 5 provides necessary power support for the operation of the motor 3 and the fingerprint assembly 4, and guarantees the normal operation of the whole system. The components are connected through lines to form an organic whole, and a series of subsequent unlocking actions are triggered after the fingerprint assembly 4 identifies correct fingerprint information.

[0041] A driving disc 6 is coaxially connected to the rotating shaft of the motor 3, and the motor 3 is immediately started and drives the driving disc 6 to rotate around the shaft after receiving a starting instruction from the fingerprint assembly 4. The edge of the driving disc 6 is designed with a first driving part 7, which extends along the circumference of the driving disc 6 and has a unique shape feature, i.e., the axial width gradually increases, thereby forming a bevel structure. The design of the bevel structure contains a subtle mechanical principle, which can convert the rotary motion into an effective pushing force on the lock tongue 2 during the rotation of the driving disc 6.

[0042] The lock tongue 2 is pushed to move and unlock by the first driving part 7 when the driving disc 6 rotates, and the shell 1 is also provided with a reset spring 8 to prevent the lock tongue 2 from moving and unlocking.

[0043] The lock tongue 2 is provided with a protruding first pushing part 9, which is accurately corresponding to the first driving part 7 on the driving disc 6. When the motor 3 is started, the driving disc 6 rotates, and the first driving part 7 also synchronously moves in a circular motion. With the rotation of the first driving part 7, the bevel gradually contacts the first pushing part 9. Due to the existence of the bevel, with the continuous rotation of the first driving part 7, the bevel will exert an increasing pushing force on the first pushing part 9, forcing the first pushing part 9 to move the lock tongue 2 in a predetermined unlocking direction. In this process, the rotary power of the motor 3 is cleverly transmitted to the lock tongue 2 through the driving disc 6 and the first driving part 7, realizing the conversion from electric energy to mechanical energy, and finally completing the unlocking action.

[0044] To ensure that the bag lock can return to the initial locking state after unlocking, the housing 1 is equipped with a reset spring 8. After completing the unlocking action, the motor 3 stops running and reverses to the original position, at which time the drive disc 6 no longer applies a pushing force to the lock tongue 2. The reset spring 8 starts to play a role by using its own elastic restoring force. It applies a pulling force to the lock tongue 2 in the opposite direction of the unlocking direction, prompting the lock tongue 2 to move in the opposite direction along the original moving path until the lock tongue 2 returns to the initial position. In the initial state, under the action of the reset spring 8, one end of the lock tongue 2 extends stably into the lock hole 14, ready for the next locking operation.

[0045] The surface of the housing 1 is provided with a lock hole 14 communicating with the inside thereof, and the moving direction of the lock tongue 2 is perpendicular to the opening direction of the lock hole 14. In the initial state, one end of the lock tongue 2 extends into the lock hole 14 under the action of the reset spring 8. This perpendicular design enables the lock tongue 2 to accurately cooperate with the lock hole 14 during movement.

[0046] It also includes a zipper buckle 18, which has a ring-shaped lock catch 19 that can be inserted into the lock hole 14. When the bag needs to be locked, the lock catch 19 of the zipper buckle 18 is inserted into the lock hole 14, at which time the extended end of the lock tongue 2 can enter the ring-shaped lock catch 19 under the action of the reset spring 8, thereby achieving firm locking of the zipper buckle 18 and ensuring the closed state of the bag to prevent accidental dropping of items. The entire locking process is simple and efficient, and through the close cooperation of the various components, it provides reliable security for the bag.

[0047] The widest part of the first driving part 7 is provided with a protruding limiting part 10. When the drive disc 6 is rotated under the drive of the motor 3, the first driving part 7 gradually comes into contact with the first pushing part 9 on the lock tongue 2 and pushes the lock tongue 2 to move to unlock. As the rotation continues, when the widest part of the first driving part 7 comes into contact with the first pushing part 9, the limiting part 10 will collide with the first pushing part 9. This collision plays a role in limiting the continued rotation of the drive disc 6, avoiding excessive rotation that can cause structural damage or abnormal unlocking action.

[0048] When the limiting part 10 collides with the first pushing part 9, the motor 3 will receive the corresponding feedback signal and then start to reverse. The reversal of the motor 3 causes the drive disc 6 to drive the first driving part 7 to rotate back to the initial position. This design ensures that after each unlocking action is completed, the drive disc 6 can be accurately reset, ready for the next unlocking, ensuring the stability and reliability of the entire unlocking mechanism.

[0049] In order to deal with situations where fingerprint unlocking fails, situations where fingerprint unlocking is not possible, and situations where customs requires unlocking, the housing 1 is also provided with a rotatable lock cylinder 11 (unlocking can be performed by inserting a key into the lock cylinder 11). The lock cylinder 11 is provided with a second driving part 12 protruding along its axis, and the lock tongue 2 is provided with a second pushing part 13 protruding, the second pushing part 13 corresponding to the second driving part 12.

[0050] When the user inserts the key and turns the lock cylinder 11, the rotation of the lock cylinder 11 drives the second drive unit 12 to rotate. Since the second drive unit 12 corresponds to the second push unit 13, the rotation of the second drive unit 12, in cooperation with the second push unit 13, transmits the rotational force to the bolt 2, thereby moving the bolt 2 and unlocking the lock. This backup mechanical unlocking method increases the practicality and emergency handling capability of the bag lock.

[0051] A pop-out block 15 that can slide along the opening direction of the lock hole 14 is connected inside the lock hole 14, and a pop-out spring 16 is provided inside the housing 1. The pop-out spring 16 always applies a spring force to the pop-out block 15 to move it in the opening direction of the lock hole 14.

[0052] In the normal locked state, the bolt 2 extends into the annular latch 19, restricting the movement of the latch 19. At this time, the pop-out block 15 is also in a compressed state, and the pop-out spring 16 accumulates elastic potential energy. When the bolt 2 is driven by the motor 3 or the lock cylinder 11 rotates and releases its restriction on the latch 19, the elastic potential energy of the pop-out spring 16 is released, pushing the pop-out block 15 to slide along the opening direction of the keyhole 14. Under the push of the pop-out block 15, the latch 19 can automatically pop out of the keyhole 14, realizing the automatic disengagement of the zipper pull 18 after unlocking, which is convenient for user operation.

[0053] To ensure the pop-out block 15 can slide stably within the keyhole 14, a slider is provided on the side of the pop-out block 15, and a sliding groove is provided on the side wall of the keyhole 14 to slide in conjunction with it. The cooperation between the slider and the sliding groove restricts the movement direction of the pop-out block 15, allowing it to slide only along the opening direction of the keyhole 14, thus preventing the pop-out block 15 from deviating or wobbling during sliding. At the same time, an anti-disengagement part is provided on the opening side of the keyhole 14, which can prevent the pop-out block 15 from falling out of the keyhole 14, ensuring that the pop-out block 15 functions within its normal operating range.

[0054] The fingerprint assembly 4 is the core component of the luggage lock that enables fingerprint unlocking. It mainly consists of a circuit board and fingerprint acquisition and recognition modules mounted on the circuit board. The battery 5 and motor 3 are electrically connected to the circuit board, and the battery 5 provides power to the various modules on the circuit board to ensure their normal operation.

[0055] The surface of housing 1 has an opening to expose the fingerprint acquisition module. When a user places their finger on the fingerprint acquisition module at the opening, the module collects the user's fingerprint information and transmits it to the fingerprint recognition module. The fingerprint recognition module compares the collected fingerprint information with a fingerprint template pre-stored on the circuit board. If the comparison matches, indicating correct fingerprint information, the fingerprint recognition module sends a start signal to motor 3 via the circuit board. Motor 3 starts and drives the drive turntable 6 to rotate, thus unlocking the door.

[0056] To ensure that battery 5 can continuously power all components of the bag lock, a charging connector 17 is installed inside the housing 1. When the battery 5 is low on power, the user can connect an external power source through the charging connector 17 to charge the battery 5. The charging connector 17 makes the bag lock more convenient to use, eliminating the need for frequent battery replacements and improving the product's efficiency and economy.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
