Description

[Technical Field]

[0002] This application belongs to the field of door lock technology, specifically relating to emergency unlocking structures. [Background Technology]

[0004] In modern home life, as people's quality of life improves and their pursuit of convenience increases, the habits of using interior doors are constantly evolving. Typically, interior doors primarily serve to separate spaces and protect privacy, with relatively low security requirements, so they don't need to be locked most of the time. This results in extremely low usage of door keys, and even in emergency situations, users often struggle to find their keys because they have been idle for a long time, causing inconvenience.

[0005] Furthermore, traditional lock designs typically expose the keyhole. While this design functionally meets basic locking and unlocking needs, it falls short in terms of aesthetics. In modern home decoration, minimalism is increasingly favored, and users have higher and higher demands for the appearance of home products. Exposed keyholes not only disrupt the overall simplicity and aesthetics of the lock but can also become a hazard for dust accumulation and accidental damage. [Utility Model Content]

[0007] To address the issues of easy key loss and insufficient aesthetics in traditional door lock designs, this application provides an emergency unlocking structure that can meet users' emergency unlocking needs while also maintaining an aesthetically pleasing and minimalist design.

[0008] This application is achieved through the following technical solution:

[0009] An emergency unlocking structure includes a door handle body and a cover that is detachably connected to the door handle body via a connecting mechanism. The door handle body and the cover cooperate to form a storage space for storing a key. The cover is used to keep the key in the storage space when stored and to remove the key from the storage space when in use.

[0010] As described above, in the emergency unlocking structure, the inner side of the cover is provided with a mounting groove for inserting one end of the key to keep the key in position with the cover.

[0011] In the emergency unlocking structure described above, the mounting slot is interference-fitted with the key.

[0012] As described above, the emergency unlocking structure includes an internal thread on the door handle body and an external thread on the cover for rotational connection with the internal thread.

[0013] In the emergency unlocking structure described above, the cover is connected to the tail of the door handle body, and the cover includes an extension portion and a chamfer portion arranged sequentially in the direction away from the door handle body.

[0014] The emergency unlocking structure described above also includes a cover plate for concealing the keyhole, and a positioning mechanism for holding the cover plate on the door handle body.

[0015] As described above, the emergency unlocking structure includes a positioning post on the cover plate, a positioning slot on the door handle body for the positioning post to be inserted, and an elastic element with its two ends connected to the bottom of the positioning slot and the positioning post respectively. The positioning slot is located on one side of the keyhole.

[0016] As described above, in the emergency unlocking structure, the door handle body is provided with a protrusion surrounding the keyhole, and the cover plate is provided with a limiting groove for the protrusion to engage. When the protrusion is embedded in the limiting groove, it restricts the cover plate from rotating relative to the door handle body with the positioning post as the rotation axis.

[0017] As described above, in the emergency unlocking structure, the cover plate has a recess along the edge of the cover plate on the side that abuts against the door handle body.

[0018] As described above, in the emergency unlocking structure, the cover plate moves outward relative to the boss, the limiting groove separates from the boss to release the restriction that the cover plate rotates relative to the door handle body about the positioning post as the rotation axis. At the same time, the elastic element is stretched by force, and the cover plate moves towards the door handle body under the elastic force of the elastic element, so that the limiting groove and the boss engage to restrict the cover plate from rotating relative to the door handle body about the positioning post as the rotation axis, or the limiting groove abuts against the boss to keep the cover plate and the boss in position.

Detailed Implementation Methods

[0032] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0033] Please see Figures 1 to 8 An emergency unlocking structure includes a door handle body 1 and a cover 3 that is detachably connected to the door handle body 1 via a connecting mechanism 2. The door handle body 1 and the cover 3 cooperate to form a storage space 5 for storing a key 4. The cover 3 is used to keep the key 4 in the storage space 5 when stored and to remove the key 4 from the storage space 5 when in use.

[0034] In this embodiment, by storing the key within the storage space formed by the door handle body and the cover, a safe and convenient key storage location is provided for the user. This design not only effectively solves the problem of easy key loss in traditional door lock designs, ensuring that users can quickly find the key when an emergency unlocking is needed, but also significantly improves the aesthetics of the door lock. Through the detachable cover, the key can be properly hidden when not in use, making the door lock's appearance more concise and in line with the minimalist aesthetic trend of modern homes. The connection mechanism can adopt various different mechanical connection methods, such as threaded connection, snap-fit ​​connection, or magnetic connection.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the inner side of the cover 3 is provided with a mounting groove 31 for inserting one end of the key 4 to keep the key 4 in position with the cover 3.

[0036] In this embodiment, by inserting one end of the key 4 into the mounting slot 31, it can be ensured that the key 4 will not shake or shift when stored in the storage space 5, thereby avoiding the problem of the key 4 being worn or making noise due to collision. Secondly, the interference fit between the mounting slot 31 and the key 4 further enhances the stability of the key 4, allowing the key 4 to be firmly locked in the storage space 5 when the cover 3 is closed, effectively preventing the risk of the key 4 being accidentally dropped or lost. In addition, this design simplifies the operation of the user to take out the key 4 in an emergency. The user can easily take out the key 4 by simply rotating the cover 3, without any additional alignment or adjustment steps.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the mounting groove 31 is interference-fitted with the key 4.

[0038] In this embodiment, the interference fit ensures that the key 4 is firmly fixed after being inserted into the mounting slot 31, effectively preventing wear or noise caused by shaking during storage or carrying. Secondly, this tight connection further enhances the stability of the key 4 within the storage space 5, avoiding the risk of accidental drop or loss and providing users with greater security. The interference fit utilizes the elastic deformation characteristics of the material. When the key 4 is inserted into the mounting slot 31, because the size of the mounting slot 31 is slightly smaller than the corresponding part of the key 4, the key 4 exerts a certain compressive force on the mounting slot 31, causing it to undergo slight elastic deformation. The reaction force generated by this deformation firmly fixes the key 4 within the mounting slot 31, achieving reliable positioning and fixation.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the connecting mechanism 2 includes an internal thread 21 provided on the door handle body 1, and an external thread 22 provided on the cover 3 for the internal thread 21 to engage and achieve a rotatable connection.

[0040] In this embodiment, the threaded connection provides a simple and reliable mechanical connection method, ensuring that the cover 3 can securely lock the key 4 in the storage space 5 when closed, effectively preventing the accidental loss of the key 4. Secondly, the connection and separation are achieved through rotation, allowing users to easily store and retrieve the key 4 without additional tools or complicated procedures, thus improving ease of use. Furthermore, the threaded connection also has a certain self-locking function, resisting certain external forces, further enhancing the stability and safety of the structure.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the cover 3 is connected to the tail of the door handle body 1, and the cover 3 includes an extension portion 32 and a chamfer portion 33 arranged sequentially in the direction away from the door handle body 1.

[0042] In this embodiment, the cover 3 is positioned at the rear of the door handle body 1, providing a concealed and easily accessible location for storing the key 4, while also avoiding interference with the main functional areas of the door handle body 1, ensuring the normal use of the door handle. Secondly, the design of the extension 32 increases the contact area between the cover 3 and the door handle body 1, improving the stability and reliability of the connection, while also providing a convenient grip for the user, making the operation of rotating and opening the cover 3 easier. The chamfered portion 33 further optimizes the appearance and feel of the cover 3, reducing potential discomfort or safety hazards from sharp edges through a smooth transition, thus enhancing the overall user experience.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a cover plate 7 for concealing the keyhole 6, and a positioning mechanism 8 for holding the cover plate 7 on the door handle body 1.

[0044] In this embodiment, the keyhole 6 can be completely hidden when not in use due to the cover plate 7, making the door lock more concise and aesthetically pleasing, in line with the minimalist aesthetic trend of modern homes. Secondly, the hidden keyhole design reduces the risk of dust accumulation and accidental damage, extending the lock's lifespan. The positioning mechanism 8 ensures that the cover plate 7 is firmly fixed to the door handle body 1 when closed, preventing accidental opening or loosening, further enhancing the stability and reliability of the structure. The positioning mechanism 8 can employ different mechanical structures, such as latches, spring pins, or magnetic elements, to meet the positioning and holding requirements in different scenarios.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the positioning mechanism 8 includes a positioning post 81 disposed on the cover plate 7, a positioning slot 82 disposed on the door handle body 1 for the positioning post 81 to be inserted, and an elastic element 83 whose two ends are respectively connected to the bottom of the positioning slot 82 and the positioning post 81, wherein the positioning slot 82 is located on one side of the keyhole 6.

[0046] In this embodiment, the positioning pin is inserted into the positioning slot, and the cover plate and the door handle body are stably connected by the tension or elasticity of the elastic element. When it is necessary to open the cover plate, the user only needs to overcome the force of the elastic element to quickly open the cover plate. This not only ensures the stability of the cover plate during normal use, but also effectively prevents the cover plate from loosening or falling off due to external force or misoperation.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, the door handle body 1 is provided with a boss 11 surrounding the keyhole 6, and the cover plate 7 is provided with a limiting groove 71 for the boss 11 to engage with. When the boss 11 is embedded in the limiting groove 71, the cover plate 7 is restricted from rotating relative to the door handle body 1 with the positioning post 81 as the rotation axis.

[0048] In this embodiment, the engagement of the boss 11 and the limiting groove 71 ensures that the cover plate 7 can be prevented from rotating unexpectedly around the positioning post 81 when closed, thereby improving the stability and safety of the structure. When the cover plate needs to be opened, it is only necessary to pull the cover plate outward a short distance to separate the boss from the limiting groove so that the cover plate can rotate and expose the keyhole.

[0049] Furthermore, as a preferred embodiment of this solution and not a limitation, the cover plate 7 has a recess 72 provided along the edge of the cover plate 7 on the side that abuts against the door handle body 1.

[0050] In this embodiment, the recessed part can form a gap between the cover plate 7 and the door handle body 1, allowing the user to open the cover plate by inserting their finger into the gap when needed, thus improving the performance of the door lock and the user experience.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, the cover plate 7 moves outward relative to the boss 11, the limiting groove 71 separates from the boss 11 to release the restriction on the cover plate 7 rotating relative to the door handle body 1 with the positioning post 81 as the rotation axis. At the same time, the elastic member 83 is stretched by force, and the cover plate 7 moves towards the door handle body 1 under the elastic force of the elastic member 83, so that the limiting groove 71 engages with the boss 11 to restrict the cover plate 7 from rotating relative to the door handle body 1 with the positioning post 81 as the rotation axis, or the limiting groove 71 abuts against the boss 11 to keep the cover plate 7 and the boss 11 in position.

[0052] In this embodiment, the principle of mechanical limiting and elastic reset is utilized. When the cover plate 7 moves outward, the limiting groove 71 separates from the boss 11, releasing the constraint on the rotational movement of the cover plate 7; simultaneously, the elastic element 83 is stretched and generates elastic force. When the user releases the cover plate 7, the elastic force of the elastic element 83 drives the cover plate 7 to move inward, causing the limiting groove 71 to re-contact with the boss 11 and achieve positioning, or after rotating a certain angle, the boss and the limiting groove are misaligned, and the boss and the limiting groove abut against each other to generate friction. This friction keeps the cover plate and the boss in position and does not cover the keyhole, making it convenient for the user to keep the keyhole unobstructed when using the key. This design is not only reliable but also adaptable to the user's operating habits.

[0053] The working principle of this embodiment is as follows:

[0054] The emergency unlocking structure of this application provides users with a safe and convenient key storage location by storing the key within a storage space formed by the door handle body and the cover. This design not only effectively solves the problem of easy key loss in traditional door lock designs, ensuring that users can quickly find the key when emergency unlocking is needed, but also significantly improves the aesthetics of the door lock. Through the detachable cover, the key can be properly hidden when not in use, making the door lock's appearance more concise and in line with the minimalist aesthetic trend of modern homes.
