Description

Technical Field

[0001] The invention belongs to the technical field of luggage, and in particular relates to a self-locking and resetting lock and a luggage. Background Art

[0002] In the field of travel goods, suitcases are an indispensable tool for people to carry when traveling, and their safety and convenience have always been the focus of consumers. Among them, locks, as an important part of suitcases, are directly related to the safety protection of luggage and the user experience. However, the suitcase locks widely used in the market still have some significant technical defects in design and function.

[0003] Most of the existing suitcase locks use a traditional mechanical lock structure, and its core unlocking mechanism relies on the user's manual operation to separate the lock tongue from the lock hook. Although this unlocking method is simple and intuitive, it has many inconveniences in practical applications. Specifically, the lock design in the prior art has the problem of "automatic relocking". That is, after the user forcibly separates the lock tongue from the lock hook, once the external force is released, the lock tongue will automatically reset under the action of the internal spring and re-combine with the lock hook, causing the phenomenon of "false unlocking". This problem is particularly prominent when heavy objects are loaded in the suitcase. Due to the pressure of the heavy object, the ability of the lock hook to bounce is limited, making it more difficult for the lock tongue to be completely released. Even if the user successfully separates the lock tongue from the lock hook, it may be locked again due to the automatic return of the lock tongue, which brings great trouble and safety hazards to the user.

[0004] In addition, the existing locks have poor adaptability and cannot automatically adjust the spring force of the lock hook according to different loading states (such as empty, half-loaded, and fully loaded). This results in the lock hook not being able to spring up smoothly when fully loaded due to the uneven weight and distribution of items in the box, which in turn affects the success rate of unlocking and the user experience.

[0005] In summary, existing suitcase locks are not convenient enough to meet consumers' demand for high-quality suitcase products. Therefore, it is necessary to innovate and improve the suitcase locks to overcome the defects of the existing technology and improve the user experience and luggage safety. Summary of the invention

[0010] When the locking assembly is driven by an unlocking external force to move from the locking position to the first unlocking position, the first unlocking holding assembly is driven by its own elastic force to move to the first unlocking matching position and cooperate with the locking assembly to lock it in the first unlocking position;

[0011] When the lock hook leaves the lock body, the second unlocking and holding component is driven to move to the second unlocking and matching position by its own elastic force and simultaneously drives the first unlocking and holding component to move to the first position, and then the locking component is driven to move to the second unlocking position by its own elastic force and matches with the second unlocking and holding component to be locked in the second unlocking position by it;

[0012] When the lock hook enters the lock body, the second unlocking and holding assembly is driven to move to the second position, and then the locking assembly is driven to move to the locking position by its own elastic force.

[0013] According to an embodiment of the present invention, the locking assembly comprises a locking member and a first elastic member, wherein the locking member is used to lock the locking hook and to cooperate with the first unlocking and holding assembly and the second unlocking and holding assembly;

[0014] The second unlocking position is located between the locking position and the first unlocking position, and the first elastic member provides elastic force for the locking member to move from the first unlocking position to the second unlocking position and from the second unlocking position to the locking position;

[0015] The unlocking external force drives the locking member from the locking position to the first unlocking position by overcoming the elastic force of the first elastic member.

[0016] According to an embodiment of the present invention, the locking assembly comprises a button, the button is connected to the locking member, and the unlocking external force is transmitted to the locking member through the button.

[0017] According to an embodiment of the present invention, the first unlocking and maintaining assembly includes a second elastic member, and the second elastic member has an elastic force to deform and move toward the locking assembly;

[0018] The second unlocking and holding assembly drives the second elastic member from the first unlocking and fitting position to the first position by overcoming the elastic force of the second elastic member.

[0019] According to an embodiment of the present invention, the second elastic member is a limiting spring piece, and the limiting spring piece is arranged between the lock body and the locking assembly.

[0020] According to an embodiment of the present invention, the second unlocking and holding assembly comprises an unlocking and holding member and a third elastic member, wherein the unlocking and holding member is used to lock the locking assembly in the second unlocking position;

[0021] The third elastic member imparts an elastic force to the unlocking retaining member to move from the second position to the second unlocking engagement position;

[0022] The lock hook drives the unlocking retaining member from the second unlocking matching position to the second position by overcoming the elastic force of the third elastic member.

[0023] According to an embodiment of the present invention, the locking assembly is provided with a locking portion, a first unlocking and holding portion, and a second unlocking and holding portion, and after the lock hook enters the lock body, it cooperates with the locking portion to achieve locking;

[0024] The first unlocking and holding component is provided with a first unlocking and holding matching portion, and the first unlocking and holding component cooperates with the first unlocking and holding portion through the first unlocking and holding matching portion to lock the locking component in the first unlocking position;

[0025] The second unlocking and retaining assembly is provided with a second unlocking and retaining matching portion, and the second unlocking and retaining assembly cooperates with the second unlocking and retaining portion through the second unlocking and retaining matching portion to lock the locking assembly in the second unlocking position.

[0026] According to an embodiment of the present invention, the locking portion is a locking tongue, and the locking hook is provided with a locking hole, and the locking hole hooks the locking tongue to achieve locking.

[0027] According to an embodiment of the present invention, the first unlocking and retaining portion is a limiting hole, and the first unlocking and retaining matching portion is a limiting column, and the limiting column is arranged in the limiting hole to achieve limiting of the locking assembly.

[0028] According to an embodiment of the present invention, the second unlocking and retaining portion is a limiting step, and the second unlocking and retaining matching portion is a limiting arm, and the limiting arm abuts against the limiting step to limit the locking assembly.

[0029] Based on the same concept, the present invention also provides a bag, comprising at least one self-locking reset lock as described in any one of the above embodiments, comprising a first box body and a second box body, wherein the lock hook and the lock body are respectively arranged on the first box body and the second box body.

[0030] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0031] The present invention has a double unlocking and holding mechanism and an automatic reset locking function. After the locking component is unlocked, it is first locked in the first unlocking position by the first unlocking and holding component, so that the unlocking state can be maintained when the lock hook has not left the lock body; then as the lock hook smoothly leaves the lock body, the second unlocking and holding component immediately intervenes, on the one hand, pushing the first unlocking and holding component to release its limiting function, and on the other hand, locking the locking component in the second unlocking position, so that the locking component has the ability to automatically reset when it is locked again; then when the lock hook enters the lock body again, the pushing force of the lock hook is used to directly trigger the second unlocking and holding component to release its limiting function on the locking component, so that the locking component can automatically reset the lock hook.

[0049] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and use inaccurate ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0050] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] Example 1

[0052] See also Figures 1 to 13The core of the present invention is to provide a self-locking reset lock, including a lock hook 4 and a lock body, the lock body including a lock shell 5 and a locking component, a first unlocking and holding component and a second unlocking and holding component movably arranged in the lock shell 5, the lock hook 4 enters the lock shell 5 and cooperates with the locking component to achieve locking, and the locking component, the first unlocking and holding component and the second unlocking and holding component all have elastic force.

[0053] The locking assembly is configured to be movable at least sequentially between a locking position, a first unlocking position, and a second unlocking position. The locking assembly locks the lock hook 4 when it is in the locking position, and unlocks the lock hook 4 when it is in the first unlocking position and the second unlocking position.

[0054] The first unlocking and holding component and the second unlocking and holding component are respectively arranged on both sides of the locking component. The first unlocking and holding component is configured to be movable at least sequentially between a first position and a first unlocking and matching position. The second unlocking and holding component is configured to be movable at least sequentially between a second position and a second unlocking and matching position.

[0055] When the locking assembly is in the locking position, the first unlocking and holding assembly is in the first position, and the second unlocking and holding assembly is in the second position through the driving of the lock hook 4.

[0056] When the locking component is driven to move from the locked position to the first unlocked position by overcoming its own elastic force through the unlocking external force, the first unlocking maintaining component is driven to move to the first unlocking mating position by its own elastic force and cooperates with the locking component to lock it in the first unlocking position. At this time, the lock hook 4 has not left the lock shell 5, and the unlocked state can be maintained by the first unlocking maintaining component when the lock hook 4 has not left the lock body.

[0057] Then, as the lock hook 4 smoothly leaves the lock shell 5, the limit of the lock hook 4 on the second unlocking and maintaining assembly disappears, and the second unlocking and maintaining assembly is driven to move to the second unlocking mating position by its own elastic force and simultaneously drives the first unlocking and maintaining assembly to move to the first position. Then, the locking assembly is driven to move to the second unlocking position by its own elastic force and cooperates with the second unlocking and maintaining assembly to be locked in the second unlocking position, so that the locking assembly can automatically reset the locking lock hook 4, laying the foundation for the subsequent automatic reset locking.

[0058] When the lock hook 4 enters the lock body again, the second unlocking and holding assembly is driven to move to the second position, and then the locking assembly is driven to move to the locking position to lock the lock hook 4 by its own elastic force.

[0059] That is to say, the present invention can not only maintain the unlocked state after unlocking, so that no manpower is required to continue to press after unlocking, but also automatically reset the locking hook 4 when locking again. The entire unlocking and relocking process only requires pressing the locking component once, and there is no need for the user to continuously intervene or perform multiple operations.

[0060] The direction in which the lock hook 4 enters the lock shell 5 and locks with the locking part is the locking direction, and the direction in which the lock hook 4 leaves the lock shell 5 is the opening direction; the direction in which the locking assembly moves from the locked position to the first unlocked position is the unlocking direction, the second unlocked position is between the locked position and the first unlocked position, and the direction in which the locking assembly moves from the first unlocked position to the second unlocked position and from the second unlocked position to the locked position is the locking direction.

[0061] In this embodiment, the locking direction and the opening direction are perpendicular to the locking direction and the unlocking direction.

[0062] The locking assembly includes a button 6, a locking member 7 and a first elastic member. The locking member 7 is used to lock the lock hook 4 and to cooperate with the first unlocking and holding member and the second unlocking and holding member. The button 6 is connected to the locking member 7. The unlocking external force is transmitted to the locking member 7 through the button 6. The first elastic member gives the locking member 7 an elastic force to move from the first unlocking position to the second unlocking position and from the second unlocking position to the locking position. The unlocking external force drives the locking member 7 from the locking position to the first unlocking position by overcoming the elastic force of the first elastic member.

[0063] Specifically, the locking member 7 is provided with a locking portion, and the lock hook 4 cooperates with the locking portion to achieve locking after entering the lock body. In this embodiment, the locking portion is a lock tongue 9, and the lock hook 4 is provided with a lock hole 19, and the lock hole 19 hooks the lock tongue 9 to achieve locking. In this embodiment, the locking member 7 is provided with a hollow cavity 8, and the lock tongue 9 is provided on the side of the hollow cavity 8 facing the unlocking direction. When the lock hook 4 is locked, it extends into the hollow cavity 8. In this embodiment, the first elastic member is a first spring 12, which is provided between the lock housing 5 and the locking member 7 to give the locking member 7 an elastic force in the locking direction, and a first spring 12 is provided at both ends of the locking member 7.

[0064] The first unlocking and holding assembly includes a second elastic member, and the second elastic member has an elastic force that deforms and moves toward the locking member 7. The second unlocking and holding assembly drives the locking member 7 from the first unlocking and matching position to the first position by overcoming the elastic force of the second elastic member. In this embodiment, the second elastic member is a limiting spring piece 13, and a plug hole 18 is provided in the lock housing 5. One end of the limiting spring piece 13 is inserted into the plug hole 18, and the other end abuts against the locking member 7 through its own elastic force. In this embodiment, a limiting spring piece 13 is provided at both ends of the locking member 7.

[0065] The locking member 7 is provided with a first unlocking and holding portion, and the limiting spring piece 13 is provided with a first unlocking and holding matching portion, and the limiting spring piece 13 cooperates with the first unlocking and holding portion through the first unlocking and holding matching portion to lock the locking member 7 in the first unlocking position. Specifically, the first unlocking and holding portion is a limiting hole 10, and the first unlocking and holding matching portion is a limiting column 14, and the limiting column 14 is provided in the limiting hole 10 to limit the locking member 7. When the limiting column 14 is not opposite to the limiting hole 10, the limiting column 14 abuts against the outer wall surface of the locking member 7, and when the locking member 7 moves, the limiting column 14 slides on the locking member 7.

[0066] The second unlocking and holding assembly includes an unlocking and holding member 15 and a third elastic member. The unlocking and holding member 15 is used to lock the locking member 7 in the second unlocking position. The third elastic member gives the unlocking and holding member 15 an elastic force to move from the second position to the second unlocking and matching position. The lock hook 4 drives the unlocking and holding member 15 from the second unlocking and matching position to the second position by overcoming the elastic force of the third elastic member. In this embodiment, the third elastic member is a second spring 17, which is arranged between the lock housing 5 and the unlocking and holding member 15. The second spring 17 gives the unlocking and holding member 15 an elastic force in the opening direction, and in this embodiment, a second spring 17 is respectively arranged at both ends of the unlocking and holding member 15.

[0067] The locking member 7 is provided with a second unlocking retaining portion, and the unlocking retaining member 15 is provided with a second unlocking retaining matching portion. The unlocking retaining member 15 cooperates with the second unlocking retaining portion through the second unlocking retaining matching portion to lock the locking member 7 in the second unlocking position.

[0068] Specifically, the second unlocking and holding portion is a limiting step 11, and the second unlocking and holding matching portion is a limiting arm 16. The limiting arm 16 abuts against the limiting step 11 to limit the locking member 7, that is, the limiting arm 16 blocks the limiting locking member 7, and the unlocking and holding member 15 pushes the limiting spring sheet 13 to the first position through the limiting arm 16. In this embodiment, a limiting arm 16 is provided at both ends of the unlocking and holding member 15, and a limiting step 11 is provided at both ends of the locking member 7.

[0069] Example 2

[0070] Another core of the present invention is to provide a bag, including at least one self-locking reset lock 3 of embodiment 1, including a first box body 1 and a second box body 2, and a lock hook 4 and a lock body are respectively arranged on the first box body 1 and the second box body 2. In this embodiment, a self-locking reset lock 3 is respectively arranged at both ends of the bag.

[0071] The working process of the present invention is further described below:

[0072] When unlocking, first, the button 6 is pressed toward the unlocking direction against the elastic force of the first spring 12. When the locking member 7 moves toward the unlocking direction to the first unlocking position, the limiting hole 10 on the locking member 7 moves to be opposite to the limiting column 14 on the limiting spring 13. The limiting spring 13 deforms and moves toward the locking member 7 by its own elastic force, so that the limiting column 14 enters the limiting hole 10 to achieve locking and holding of the locking member 7 and lock it in the first unlocking position. At this time, since the lock hook 4 has not left the lock housing 5, the lock hook 4 has always overcome the elastic force of the second spring 17 and pressed against the unlocking retainer 15 to limit the unlocking retainer 15 to the second position.

[0073] When the first box body 1 and the second box body 2 are separated, the lock hook 4 moves toward the opening direction and leaves the lock shell 5, and the limit of the lock hook 4 on the unlocking retaining member 15 disappears. The unlocking retaining member 15 moves toward the opening direction by the elastic force of the second spring 17, and the limit arm 16 on the unlocking retaining member 15 first moves to the side of the limit step 11 on the locking member 7 toward the locking direction, but does not contact the limit step 11, that is, at this time, there is still a gap between the limit arm 16 and the limit step 11; then the limit arm 16 moves to contact the limit spring piece 13, and overcomes the elastic force of the limit spring piece 13 to push the limit spring piece 13, so that it deforms and moves away from the locking member 7, so that the limit column 14 leaves the limit hole 10, at this time, the limit of the limit spring piece 13 on the locking member 7 disappears, and the locking member 7 moves toward the locking direction by the elastic force of the first spring 12, until it moves to the limit step 11 and abuts against the limit arm 16, and at this time, the locking member 7 is limited to the second unlocking position by the unlocking retaining member 15.

[0074] Finally, when the first box body 1 and the second box body 2 are closed, the lock hook 4 moves toward the locking direction and enters the lock shell 5, and enters the hollow cavity 8 of the locking piece 7. Then the lock hook 4 contacts the unlocking retaining piece 15 and overcomes the elastic force of the second spring 17 to push it, so that the unlocking retaining piece 15 moves toward the locking direction. When the limiting arm 16 on the unlocking retaining piece 15 moves to be misaligned with the limiting step 11, the limiting of the locking piece 7 by the unlocking retaining piece 15 disappears, and the locking piece 7 moves to the locking position in the locking direction by the elastic force of the first spring 12. The lock tongue 9 in the hollow cavity 8 enters into the lock hole 19 of the lock hook 4 to realize the locking of the lock hook 4, and the first box body 1 and the second box body 2 are locked.

[0075] The present invention can keep the unlocked state after unlocking, so that there is no need for manpower to keep pressing after unlocking, and even if the bag is placed flat on the table and the bag is loaded inside, there is no need to keep pressing the two buttons 6 to open the box. The button 6 can be directly pressed, and the inside of the lock body will keep the unlocked state until the box is opened, and then it can be locked again.

[0076] The present invention can also automatically reset the locking hook 4 when locking again, and the entire unlocking and relocking process only requires pressing the button 6 once, without the need for continuous user intervention or multiple operations.

[0077] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
