[0002] In people's daily life and travel, luggage is widely used as an important storage tool. To ensure the safety of the items in the luggage, a combination lock has become an essential accessory for the luggage.

[0003] Many inconveniences have emerged during the use of traditional push-type unlocking luggage locks. On the one hand, the push-type unlocking method is relatively single. Once mechanical failures or component damages occur, it is very likely that the luggage cannot be opened normally, bringing great troubles to users. For example, the push structure may become stuck due to long-term use, making it impossible for users to quickly open the luggage in case of emergency. On the other hand, the security of push-type unlocking is relatively low. This unlocking method is easily cracked by lawbreakers using some simple tools, thus threatening the safety of the items in the luggage.

[0004] In addition, the operation experience of push-type unlocking also needs to be improved. For some users with less strength, it may require a relatively large amount of force to push and unlock, making it laborious to use. Moreover, the feedback of push-type unlocking is not obvious, and users often have difficulty determining whether the unlocking is successful, which is prone to misoperation.

[0005] Under such a background, there is an urgent need in the market for a safe and convenient luggage combination lock that can overcome the various inconveniences of push-type unlocking and provide users with a better use experience and higher security guarantee. Summary of the Utility Model

Detailed Embodiments

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0040] Please refer to Figures 1-7 , in the embodiment of the present utility model, a multi-functional linkage luggage combination lock includes a lock case 1. A locking mechanism and a locking member 2 connected to the locking mechanism are provided on the lock case 1. The locking member 2 has an unlocking position and a locking position, and can be driven by the locking mechanism to slide and switch between the unlocking position and the locking position.

[0041] The locking mechanism includes a password wheel assembly 3, a lock core assembly 4, and a button 5. The password wheel assembly 3 is slidably abutted against one side of the button 5. The lock core assembly 4 is rotatably connected within the button 5. Among them, the password wheel assembly 3 has a first locking tongue 6 that is linked with the locking member 2, and the lock core assembly 4 has a second locking tongue 7 that is linked with the locking member 2.

[0042] By releasing the abutment restriction on the button 5 by the password wheel assembly 3, it is allowed to press down the button 5 to drive the first locking tongue 6 to slide and drive the locking member 2 to slide and switch from the locking position to the unlocking position, or by releasing the restriction on the second locking tongue 7 by the lock core assembly 4, it is allowed to rotate the second locking tongue 7 and drive the locking member 2 to slide and switch from the locking position to the unlocking position.

[0043] In the technical solution of the present utility model, the luggage combination lock mainly consists of a lock case 1, a locking mechanism, and a locking member 2. The lock case 1 provides support and protection for the entire combination lock. The locking member 2 has an unlocking position and a locking position, and realizes position switching through the drive of the locking mechanism, thereby completing the opening and locking of the luggage.

[0044] The locking mechanism includes a password wheel assembly 3, a lock core assembly 4, and a button 5. The password wheel assembly 3 is slidably abutted against one side of the button 5. The lock core assembly 4 is rotatably connected within the button 5. This structural design enables the password wheel assembly 3 and the lock core assembly 4 to interact with the button 5 in different ways respectively, and further control the state of the locking member 2. Specifically:

[0045] The password wheel assembly 3 has a first locking tongue 6 linked to the locking member 2. When the correct password is entered, the internal structure of the password wheel assembly 3 changes, releasing the abutting restriction on the button 5. At this time, the button 5 can be pressed. The downward pressing of the button 5 drives the first locking tongue 6 to slide, and the sliding of the first locking tongue 6 further drives the locking member 2 to slide from the locked position to the unlocked position. In this process, the button 5 acts as a medium for force transmission, accurately transmitting the force of the user pressing the button 5 to the first locking tongue 6, thus realizing the unlocking operation. Its design needs to have a certain strength and stability to ensure that it will not be damaged or malfunction during repeated use;

[0046] The lock core assembly 4 has a second locking tongue 7 linked to the locking member 2. When a key is inserted into the lock core assembly 4 and the correct operation is performed, the lock core assembly 4 rotates, releasing the restriction on the second locking tongue 7 and allowing the second locking tongue 7 to rotate. The rotation of the second locking tongue 7 can also drive the locking member 2 to slide from the locked position to the unlocked position. In this process, although the button 5 is not directly pressed as in password unlocking, it still closely cooperates with the lock core assembly 4, providing a stable support and connection point for the rotation of the lock core assembly 4.

[0047] In summary, this luggage password lock has two unlocking methods: password unlocking and key unlocking, overcoming the problem of the single unlocking method of traditional push unlocking. Users can choose the appropriate unlocking method according to the actual situation. When they forget the password, they can use the key to unlock, improving the convenience of use. And the button 5, as the common trigger point of the two unlocking methods, provides a unified operation interface for users, making it more convenient and fast for users during use;

[0048] Compared with the traditional push unlocking which is easy to be cracked, the password wheel assembly 3 and the lock core assembly 4 of this luggage password lock increase the difficulty of cracking. The setting of the password can improve security and is not easy to be spied on and cracked by others; Only those who have the correct key can open the lock with key unlocking, effectively preventing lawbreakers from cracking the luggage lock with simple tools and ensuring the safety of the items in the luggage;

[0049] For users with less strength, they don't need to push hard as in push unlocking. They only need to enter the correct password or use the key to easily unlock, reducing the operation difficulty and being more labor-saving. The design of the button 5 conforms to the ergonomic principle, and users can easily press the button 5 without consuming too much effort, improving the operation convenience;

[0050] After the password is entered correctly or the key operation is correct, the downward pressing of the button 5 or the rotation of the lock core assembly 4 will give obvious feedback to the user. The user can clearly know whether the unlocking is successful, reducing the possibility of misoperation. The feedback mechanism of the button 5 can be presented to the user through touch, sound or vision, etc., making the user more at ease during use.

[0051] In the embodiment of the present utility model, the locking member 2 is horizontally slidably mounted on the housing, and is unlocked or locked by the password wheel assembly 3 or the lock core assembly 4 to drive the locking member 2 to slide along the length direction of the lock housing 1, so as to realize the sliding switch between the unlocking position and the locking position.

[0052] The locking member 2 is horizontally slidably mounted on the housing. This mounting method enables the locking member 2 to stably slide horizontally on a specific track. When the password wheel assembly 3 or the lock core assembly 4 performs unlocking or locking operations, a corresponding driving force will be generated. This driving force can be transmitted to the locking member 2 along a specific direction, prompting the locking member 2 to slide along the length direction of the lock housing 1. Through this sliding switch, the locking member 2 can accurately change its position between the unlocking position and the locking position, thereby realizing the opening and locking functions of the luggage password lock.

[0053] In the embodiment of the present utility model, the button 5 is vertically elastically mounted on the housing. The password wheel assembly 3 includes a password wheel 8 and a corresponding password wheel connecting rod 9. The password wheel connecting rod 9 is horizontally slidably mounted on the housing. A first abutting block 10 is provided on one side of the button 5, and a second abutting block 11 that cooperates with the first abutting block 10 is provided on one side of the password wheel connecting rod 9, and the mating surface of the second abutting block 11 and the first abutting block 10 is an inclined surface;

[0054] Wherein, a first locking tongue 6 is extended and provided at the lower end of the second abutting block 11.

[0055] The button 5 is vertically elastically mounted on the housing, which means that the button 5 is subjected to an upward elastic force in the normal state. When an external force presses the button 5, the button 5 moves downward against the elastic force. When the external force disappears, the button 5 can automatically reset under the action of the elastic force; the password wheel assembly 3 includes a password wheel 8 and a corresponding password wheel connecting rod 9. After the correct password is input on the password wheel 8, the restriction on the password wheel connecting rod 9 is released. At this time, the password wheel connecting rod 9 is in a movable state, waiting for the action of an external force. After the password wheel 8 releases the restriction on the password wheel connecting rod 9, the user presses the button 5. The button 5 is vertically elastically mounted on the housing and moves downward against the elastic force of elastic elements such as springs when pressed. Since the mating surface of the first abutting block 10 on one side of the button 5 and the second abutting block 11 on one side of the password wheel connecting rod 9 is an inclined surface, as the button 5 is pressed downward, the button 5 generates a horizontal component force on the password wheel connecting rod 9. This component force forces the password wheel connecting rod 9 to slide horizontally. When the password wheel connecting rod 9 slides horizontally, it drives the first locking tongue 6 extended and provided at its lower end to move together. Since the first locking tongue 6 is linked with the locking member 2, the locking member 2 moves along with it, thereby realizing the sliding switch of the locking member 2 from the locking position to the unlocking position and completing the unlocking process.

[0056] Through the precise control of the password wheel link 9 by the password wheel 8, it is ensured that subsequent operations can only be carried out when the password is correct, improving the security of the password lock and preventing illegal opening. At the same time, the design of the inclined surface cooperation enables the pressing action of the button 5 to be accurately converted into the horizontal sliding of the password wheel link 9, achieving precise motion transmission.

[0057] Among them, the button 5 can be understood as a hollow housing.

[0058] In the embodiment of the present utility model, the password wheel assembly 3 further includes a plurality of annular portions 12 sleeved on the password wheel link 9. The plurality of annular portions 12 are respectively and correspondingly clamped with the plurality of password wheels 8. Among them, a convex block 13 protrudes inwardly from each of the plurality of annular portions 12, and a through groove 14 for the plurality of convex blocks 13 to pass through together is provided on the password wheel link 9.

[0059] The plurality of annular portions 12 in the password wheel assembly 3 are respectively and correspondingly clamped with the plurality of password wheels 8, which means that each password wheel 8 has a corresponding annular portion 12 and they are connected together by clamping. This connection method enables the rotation of the password wheel 8 to drive the annular portion 12 to move together; the annular portion 12 is sleeved on the password wheel link 9, and when the password wheel 8 rotates, the annular portion 12 rotates correspondingly on the password wheel link 9;

[0060] A convex block 13 protrudes inwardly from each of the plurality of annular portions 12, and a through groove 14 for the plurality of convex blocks 13 to pass through together is provided on the password wheel link 9. After the correct password is input by rotating the password wheel 8, the plurality of annular portions 12 can rotate under the drive of the corresponding password wheel 8, so that the plurality of convex blocks 13 and the through groove 14 are in a relative position, thereby realizing the release of the restriction of the password wheel 8 on the password wheel link 9 and allowing the password wheel link 9 to move.

[0061] In the embodiment of the present utility model, the lock core assembly 4 includes a connecting member 15 that is clamped and cooperated with the button 5, and a lock core 16 and a transmission member 17 integrated between the button 5 and the connecting member 15. The lock core 16 is linked with the transmission member 17 and is rotatably connected within the connecting member 15;

[0062] Among them, a second lock tongue 7 is extended and provided at the lower end of the transmission member 17.

[0063] The lock core assembly 4 is composed of a connecting member 15 that is snap-fitted with the button 5, a lock core 16, and a transmission member 17. The connecting member 15 plays a role in connection and support, integrating the lock core 16 and the transmission member 17 between the button 5 and the connecting member 15. The lock core 16 and the transmission member 17 are linked. When a key is inserted into the lock core 16 and rotated, the rotation of the lock core 16 will drive the transmission member 17 to move together. A second locking tongue 7 is provided at the lower end of the transmission member 17. When the rotation of the lock core 16 drives the transmission member 17 to move, the movement of the transmission member 17 further drives the second locking tongue 7 to perform corresponding actions. Similar to the password wheel assembly 3, the action of the second locking tongue 7 will be linked with the locking member 2 to achieve the sliding switching of the locking member 2 between the unlocking position and the locking position.

[0064] Integrating the lock core 16, the transmission member 17, and the connecting member 15 between the button 5 and the connecting member 15 makes the structure of the lock core assembly 4 more compact. This design can realize multiple functions within a limited space, without occupying too much space in the luggage, and at the same time improves the overall aesthetics of the password lock.

[0065] In the embodiment of the present utility model, a first long hole 18 is formed on the surface of the locking member 2, and the lower end of the first locking tongue 6 is placed in the first long hole 18 and is slidably connected to the first long hole 18;

[0066] A second long hole 19 is formed on the surface of the locking member 2, and the lower end of the second locking tongue 7 is placed in the second long hole 19 and is slidably connected to the second long hole 19;

[0067] Wherein, the first long hole 18 and the second long hole 19 are respectively located on both sides of the locking member 2.

[0068] In the locked state, the first locking tongue 6 is located on the left inner side of the first long hole 18 (the specific direction can be determined according to the actual situation), and the second locking tongue 7 is located on the left inner side of the second long hole 19. This initial position ensures that the locking member 2 is in the locked position, preventing the luggage from being opened randomly;

[0069] When unlocking through the password wheel assembly 3, the first locking tongue 6 abuts against the left inner side of the first long hole 18 and slides to the left. The sliding of the first locking tongue 6 drives the locking member 2 to slide, thereby realizing the switching from the locked position to the unlocked position. At this time, due to the movement of the locking member 2, the second long hole 19 will also change its position relative to the second locking tongue 7, so that during the unlocking process of the password wheel assembly 3, the second locking tongue 7 will not cause unnecessary interference to the sliding of the locking member 2;

[0070] When unlocking through the lock core assembly 4, the principle is similar. The rotation of the lock core 16 drives the transmission member 17 to move, causing the second lock tongue 7 to slide in the second long hole 19. The second lock tongue 7 abuts against the left inner side of the second long hole 19 and slides to the left, thereby driving the locking member 2 to slide and switch to the unlocking position. At this time, the first long hole 18 will also undergo a corresponding position change relative to the first lock tongue 6, so that during the unlocking process of the lock core assembly 4, the first lock tongue 6 will not cause unnecessary interference to the sliding of the locking member 2.

[0071] In the embodiment of the utility model, a sliding groove 20 is provided along the surface of the connecting member 15 and is slidably matched with the second locking tongue 7. The second locking tongue 7 passes through the sliding groove 20 to cooperate with the second long hole 19, wherein the sliding path of the second locking tongue 7 in the sliding groove 20 at least partially overlaps with the sliding path of the second locking tongue 7 in the second long hole 19.

[0072] A slide groove 20 is provided along the surface of the connecting member 15, and the second lock tongue 7 is slidably matched with the slide groove 20. When the lock core assembly 4 is working, the lock core 16 rotates to drive the transmission member 17 to move, thereby causing the second lock tongue 7 to slide in the slide groove 20. After passing through the slide groove 20, the second lock tongue 7 is matched with the second long hole 19 on the locking member 2, that is, the movement of the lock core assembly 4 is transmitted to the locking member 2 through the sliding of the second lock tongue 7 in the slide groove 20 and the second long hole 19, thereby realizing the sliding switching of the locking member 2;

[0073] The sliding path of the second lock tongue 7 in the slide groove 20 at least partially overlaps with the sliding path in the second long hole 19, so that the movement trajectory of the second lock tongue 7 is continuous to a certain extent during the process of transmitting the movement from the lock core assembly 4 to the locking member 2. This design can ensure the smoothness and accuracy of the movement and reduce the jamming or failure caused by the discontinuous movement path;

[0074] The continuous sliding path of the second lock tongue 7 in the slide groove 20 and the second long hole 19 increases the stability of the movement and reduces the possibility of shaking or deviation of the second lock tongue 7 due to sudden changes in the direction of movement or uneven force. This stable movement helps to improve the overall performance and service life of the combination lock. At the same time, the slide groove 20 is opened on the surface of the connecting member 15, making full use of the space and making the connection between the lock core assembly 4 and the locking member 2 more compact. This design can realize complex motion transmission without increasing too much volume, and is suitable for application scenarios with limited space such as luggage.

[0075] The slide groove 20 and the second locking tongue 7 may be fan-shaped or arc-shaped structures.

[0076] In the embodiment of the utility model, the connecting member 15 and the transmission member 17 are both provided with a notch 21 for making way for the second stopper 11 .

[0077] Notches 21 are provided in both the connecting member 15 and the transmission member 17. This notch 21 is for making way for the second abutting block 11 on the password wheel connecting rod 9. When the password wheel assembly 3 works, during the horizontal sliding process of the second abutting block 11 on the password wheel connecting rod 9, it may interfere with the positions of the connecting member 15 and the transmission member 17. By providing the notch 21, a space for avoidance is provided for the second abutting block 11, ensuring that the movement of the password wheel connecting rod 9 will not be hindered by the connecting member 15 and the transmission member 17.

[0078] In the embodiment of the present utility model, an elastic member 22 cooperating with the button 5 is provided at a position corresponding to the connecting member 15 inside the housing. Among them, a connecting end 23 that abuts against the elastic member 22 is provided at the lower end of the connecting member 15.

[0079] The provision of the elastic member 22 provides the button 5 with an automatic reset function. When the password is entered incorrectly or the password lock is not needed, the user releases the button 5, and the elastic force of the elastic member 22 can quickly bounce the button 5 back to the initial position, facilitating the user's next operation. This automatic reset function improves the convenience of using the password lock and reduces the user's operation steps.

[0080] Furthermore, the lock core assembly 4 is rotatably connected to the button 5, and the lock core assembly 4 can be pressed down together with the button 5, specifically as follows:

[0081] When unlocking through the password wheel assembly 3, after the password wheel 8 releases the restriction on the password wheel connecting rod 9 when the correct password is entered, at this time, pressing the button 5, the pressing action of the button 5 forces the password wheel connecting rod 9 to slide horizontally through the inclined plane cooperation, and then drives the first lock tongue 6 to slide in the first long hole 18, realizing the drive of the locking member 2 to switch it from the locking position to the unlocking position. During this process, due to the clamping cooperation between the connecting member 15 in the lock core assembly 4 and the button 5, and the integration of the lock core 16 and the transmission member 17 between the button 5 and the connecting member 15, when the button 5 is pressed down, the lock core assembly 4 can be pressed down together;

[0082] The lock core 16 and the transmission member 17 are linked and rotatably connected inside the connecting member 15. When using a key to insert into the lock core 16 for unlocking operation, the rotation of the lock core 16 drives the movement of the transmission member 17, and the second lock tongue 7 at the lower end of the transmission member 17 slides in the chute 20 and the second long hole 19, thereby driving the locking member 2 to unlock. During the unlocking process of the password wheel assembly 3, although the lock core assembly 4 is pressed down together, due to its special structural design, the rotational connection mode of the lock core 16 and the transmission member 17 inside the connecting member 15 enables them to rotate relative to the button 5 while being pressed down by the button 5, which not only ensures the coordinated work of each component in different unlocking methods but also meets the independent operation requirements of the lock core assembly 4 in specific situations;

[0083] Among them, the connecting member 15 plays a key connecting role in the whole structure. On the one hand, it is clamped and matched with the button 5, so that when the button 5 is pressed down, it can drive the whole lock core assembly 4 to move; on the other hand, it provides installation and rotation support for the lock core 16 and the transmission member 17. The transmission member 17 plays a role in transmitting motion in the lock core assembly 4.
