Description

Technical Field

[0001] This utility model relates to the field of item management technology, and in particular to an important item storage cabinet. Background Technology

[0002] Keys, as special items, play a vital role in enterprises and institutions. Theft or loss of keys due to management negligence can lead to significant security risks or substantial losses. However, the materials and shapes of keys vary greatly, making direct information management of the keys themselves very difficult. Using standardized smart keychains to manage keys is highly effective and convenient.

[0003] In existing technologies, there are various management methods for smart keychains. Some methods determine whether a key is lost by detecting changes in the weight of the key attached to the keychain, but this method faces many challenges in practical applications. For example, when the keychain and key are attached and placed in a pocket or bag, collisions and friction between the key and keychain during walking inevitably occur, making it impossible to accurately measure the weight of the key, thus making this method difficult to apply in practice.

[0004] Another type of smart keychain attempts to locate lost keys by having voice recognition and speakers built into it, through manual calling. However, when multiple keychains are placed together, it is impossible to accurately distinguish which keychain responded to the call, making it impossible to determine which keychain was lost.

[0005] In addition, there is another type of smart keychain that incorporates a positioning device and a signal transceiver. This allows it to sense changes in the distance between the keychain and the handheld terminal. When the distance exceeds a preset range, the keychain will issue an alarm and location alert to prevent key loss and facilitate key retrieval. However, this type of keychain is not only expensive but also exhibits significant shortcomings in multi-keychain management scenarios. Due to the lack of a recognition device, this keychain cannot achieve accurate and effective management when handling tasks such as keychain retrieval, return, and scheduled inventory checks.

[0006] In view of the shortcomings of the above technologies, safe deposit boxes for important items (specifically referring to smart key cabinets that integrate intelligent management functions) have emerged. These safe deposit boxes centralize smart key fobs into a single smart cabinet, aiming to provide comprehensive, secure, digital, and intelligent management of the smart key fobs.

[0068] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0069] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such usage can be interchanged where appropriate. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a system, product, or device that comprises a series of units is not necessarily limited to those explicitly listed, but may include other units not explicitly listed or inherent to such products or devices.

[0070] Example 1

[0071] like Figure 9 As shown, this embodiment provides a safe for important items, including a cabinet body 4, wherein the cabinet body 4 includes at least one such as Figure 7 The first storage compartment 3 (or key storage compartment) shown is used to store important items such as keys. Multiple first storage compartments 3 can be combined and used in a specific layout and order to form an important item storage cabinet (or smart key cabinet), such as being distributed in rows horizontally, columns vertically, or arrays in both horizontal and vertical directions.

[0072] One or more first storage compartments 3 in an important goods storage cabinet work collaboratively through a unified connection interface and control system. Each first storage compartment 3 has an independent antenna control board, enabling self-circuit control and independent operation. This allows the main control system of the important goods storage cabinet to manage and control each first storage compartment 3 more efficiently.

[0073] Combination Figure 7 As shown, each of the first accommodating compartments 3 includes a compartment body 31, a compartment door 32, and a smart key fob.

[0074] The compartment 31 has a cavity for storing keychains.

[0075] The compartment door 32 is closed by an electromagnetic lock 313 to seal the opening of the compartment body 31. The compartment door 32 can only be opened under authorized operation (such as through identity verification methods such as password or fingerprint). The compartment door 32 is equipped with an observation window.

[0076] Among them, smart keychains, see Figures 1-6 As shown, it specifically includes two parts: a key fob 1 and a key fob storage unit 2.

[0077] The keychain 1 has a first through hole 11 and a receiving portion 13. The first through hole 11 extends through the thickness direction of the keychain 1. The receiving portion 13 is located at the front end (i.e., the insertion end) of the keychain 1, and an IC card 14 is embedded in the receiving portion 13. The IC card serial number is a key recognition module.

[0078] The key fob storage unit 2 includes a key fob socket 21 and an antenna control board 22. The key fob socket 21 includes a panel with a jack 211 and a cavity communicating with the jack 211. The jack 211 allows the key fob 1 to be inserted into the cavity. A hook 212 is provided in the cavity; when the front end of the key fob 1 is inserted into or removed from the cavity, the hook 212 engages with the first through hole 11, locking the hook 212 within or releasing it from the first through hole 11. The antenna control board 22 is installed in the cavity of the key fob socket 21. The antenna control board 22 integrates a card reader module and an antenna, enabling wireless communication with the IC card 14 of the key fob 1 via the antenna to read the IC card serial number. This serial number can be recorded as the identification code of the key fob 1 in the key cabinet management system. The antenna is integrated into the antenna control board 22; this design not only simplifies the structure but also improves reliability and performance. Because the antenna and card reader module are tightly integrated, signal transmission between them is more direct and efficient, reducing signal loss and interference, thereby improving card reading speed and accuracy. Furthermore, the integrated design reduces the number of external connection cables and interfaces, lowering the risk of failure and improving overall stability and durability. It also makes the key fob storage unit 2 more compact, facilitating installation and portability.

[0079] Those skilled in the art will understand that the antenna may not be integrated into the antenna control board 22, but may instead be a separate component, separately arranged and adjacent to the antenna control board 22. Specifically, for example... Figure 1 In one embodiment shown, the antenna 23 and the antenna control board 22 are separately arranged. When the key fob 1 is inserted into the key fob socket 21, the antenna 23 is located between the receiving part 13 of the key fob 1 and the antenna control board 22. That is, the antenna 23 is physically located between the IC card and the antenna control board 22 so that the antenna control board 22 can transmit signals to the IC card in the receiving part 13 through the antenna 23.

[0080] For details, please refer to Figure 2 The diagram illustrates the structure of a keychain 1, which has a flat upper and lower surface with smooth transitions at the side edges. Of course, the keychain 1 is not limited to the shape shown. The receiving portion 13 includes a circular groove on the keychain 1 and a circular end cap 15 that seals the opening of the circular groove. The IC card 14 is adhered to the receiving portion 13. The circular end cap 15 is non-removably connected to the circular groove. For example, by using ultrasonic welding technology, the circular end cap 15 can be connected to the circular groove, making it impossible to remove the IC card 14 without damaging the structure. This design prevents the IC card 14 from being stolen.

[0081] In a preferred embodiment, the rear end of the key buckle 1 is further provided with a second through hole 12, on which a structural member 16 for installing a key (such as...) is hung (e.g., ...) on the second through hole 12. Figure 3 (As shown). The key mounting component 16 can be a detachable key ring or a non-detachable one. When using a non-detachable key mounting component 16, if the key mounting component 16 is damaged, it means that the key on the keychain 1 may have been illegally stolen. This ensures the security, uniqueness, and reliability between the keychain and the connected key.

[0082] See Figures 4-5 The diagram shows a structural schematic of a key fob storage unit. The hook 212 has a fixed end and a free end. The fixed end is fixedly installed in the cavity of the key fob socket 21, and the free end faces the insertion hole 211 and has a snap-fit ​​protrusion. The snap-fit ​​protrusion includes an arc-shaped protrusion end or a triangular protrusion end. Figure 6 As shown, when the front end (insertion end) of the key fob 1 is inserted into the internal cavity of the key fob socket 21, pressure is first applied to the locking protrusion. As the front end of the key fob 1 continues to be inserted, the locking protrusion of the hook 212 engages with the first through hole 11 of the key fob 1, and is in a locked state without the need for external force. In this embodiment, the key fob socket 21 has a through-type light groove 213 on the panel with the insertion hole 211. The light groove 213 is a U-shaped groove, and the opening of the U-shaped groove extends to the edge of the panel of the key fob socket 21, forming an opening groove. An indicator light 221 is provided at the bottom of the U-shaped groove, and the indicator light 221 is electrically connected to the antenna control board 22. When the front end of the key fob 1 is inserted to a preset position and the hook 212 is locked in the first through hole 11, the antenna control board 22 will receive a signal and control the indicator light 221 to light up, indicating to the user that the key fob 1 has been correctly inserted, so that the user can quickly confirm the connection status between the key fob 1 and the key fob socket 21.

[0083] In a preferred embodiment, the key ring socket 21 is made of PC material. PC material has a certain degree of flexibility and elasticity, allowing the hook 212 to deform slightly to accommodate the insertion and removal process, thus enabling repeated insertions and removals without easily causing damage. See also... Figure 7 As shown, in this embodiment, the back plate of the compartment 31 has a mounting hole 311, and the smart keychain socket 21 is installed on the outside of the back plate (i.e., the side away from the inside of the compartment 31). The insertion hole 211 on the panel of the keychain socket 21 is directly opposite the mounting hole 311 of the back plate.

[0084] On the back panel of the compartment 31, in addition to the mounting hole 311 reserved for the smart key fob storage unit 2, an indicator light hole 312 is also provided. The indicator light 221 of the key fob socket 21 is directly opposite the indicator light hole 312 on the back panel. When the key fob 1 is inserted into place, the light from the indicator light 221 on the key fob storage unit 2 can be emitted through the indicator light hole 312 on the back panel, providing the user with intuitive visual feedback.

[0085] When a user needs to store a key, they simply connect the key to the key-mounting structure 16 of the key ring 1, and then insert the key ring 1 into the socket 211 of the key ring socket 21 through the mounting hole 311 on the back plate. To retrieve the key, the user must first open the compartment door 32 through the authorized operation of the electromagnetic lock 313, and then pull out the key ring 1 to obtain the key.

[0086] In a practical application scenario, the first storage compartment 3 of this embodiment can be used as a modular unit, allowing it to be spliced ​​and combined as an independent storage module within an important items storage cabinet. This makes the important items storage cabinet more flexible and convenient to expand its functions, increase its storage capacity, or adjust its layout. Users can change the number and layout of the first storage compartments 3 at any time according to actual needs to meet the application requirements of important items storage cabinets of different sizes and needs, without having to replace the entire important items storage cabinet.

[0087] like Figure 8 As shown, the two first storage compartments 3 can also be tightly spliced ​​together by specific connection structures (such as buckles, bolts, etc.) to form a larger storage module.

[0088] Understandably, in practical applications, users can choose different numbers of the first storage compartments 3 to combine with existing storage cabinets according to their actual needs, in order to meet the needs of item management of different scales and functions.

[0089] In enterprises and institutions, key management involves multiple stages, such as key storage, safekeeping, and inventory. Existing smart keychain technology, such as managing keys by weighing the keys connected to a single keychain, cannot effectively monitor the key storage, retrieval, and inventory processes, nor can it guarantee key security. When keys are taken or replaced, this technology cannot provide effective management. For example, if smart keychains are equipped with voice recognition and speakers to locate lost keys through manual announcements, it's difficult to distinguish which keychain responded to the announcement when multiple keychains are placed together, making it impossible to accurately identify which key is missing. Another example is using positioning and signal transceiver devices within the smart keychain to sense the distance between the keychain and a handheld terminal. When the distance exceeds a preset range, alarms and location indicators can be triggered to prevent key loss and facilitate key retrieval. However, such keychains are not only expensive, but also lack an effective identification mechanism when managing multiple keychains, making it impossible to accurately manage the keychain retrieval, return, and inventory processes.

[0090] In summary, the smart keychain of this embodiment includes a keychain and a keychain storage unit. By embedding an IC card within the keychain and using a card reader module in the keychain storage unit to wirelessly communicate with an antenna, the IC card serial number is read as the key identification module. When the keychain and keychain socket are connected, they are simply aligned and inserted; the locking protrusion automatically engages with the first through hole, making operation convenient and quick. The first storage compartment 3 of this embodiment adopts a modular design, allowing for easy combination according to actual needs. This gives the important items storage cabinet advantages in terms of functional expansion, increased storage capacity, layout adjustment, and reduced maintenance costs. It improves the flexibility and scalability of the important items storage cabinet, avoiding the cumbersome and wasteful replacement of the entire cabinet due to changing needs, and reducing user maintenance costs and ease of use.

[0091] Example 2

[0092] This embodiment provides a safe for important items, including a cabinet body 4. The cabinet body 4 includes at least one first storage compartment 3 as described in Embodiment 1, for storing important items such as keys. Furthermore, to enhance storage flexibility and practicality, the cabinet body 4 in this embodiment also includes multiple independent second storage compartments of the same or different sizes, allowing users to store items of varying sizes.

[0093] like Figure 10 As shown, this important items storage cabinet not only includes a first compartment 3 specifically for storing keys, but also multiple functional areas such as small item storage boxes 45, medium-sized item storage boxes 42, medium item storage boxes 43, and large item storage boxes 44. Each second compartment is equipped with an independent door and electromagnetic lock.

[0094] In a preferred embodiment, to optimize item management efficiency, the cabinet 4 further includes an RFID reader / writer, and independent RFID directional near-field antennas 432 are installed in some or all of the second storage compartments to facilitate item inventory. Items stored in the second storage compartments are affixed with RFID electronic tags, which wirelessly communicate with the RFID reader / writer via the RFID directional near-field antennas 432. Specifically, as... Figure 11 As shown, taking the large item storage box 44 as an example, its internal structure includes an antenna mounting plate 431 for installing an RFID directional near-field antenna 432, and is equipped with a network port 433 for data transmission, as well as a five-hole socket 434 to meet power requirements.

[0095] In a preferred embodiment, the front of the cabinet 4 is further provided with an identity recognition module and a human-computer interaction module 41. The identity recognition module is used to identify the user's identity before storing or retrieving items, and supports the combined use of single or multiple biometric methods, including but not limited to user fingerprints (such as fingerprints). Figure 10 The system includes fingerprint scanners (414), voiceprint scanners, and facial recognition devices to ensure that only authorized users can access the safe deposit box for important items. The human-computer interaction module 41 may include a display screen 412, a speaker 413, and a camera 411. The human-computer interaction module 41 displays detailed information related to the items, such as the item's storage location and storage time, allowing users to intuitively understand the current status of the safe deposit box. Furthermore, the human-computer interaction module 41 can also receive user input. Users can complete operations such as storing and retrieving items through various interaction methods such as touch screen and voice commands. The content of the interaction is not limited to text information but also includes images and sound.

[0096] This embodiment of the important item storage cabinet, based on Embodiment 1, further introduces a second storage compartment design with diverse sizes and integrates advanced RFID inventory technology. By combining the first storage compartment 3 with second storage compartments of various sizes, this embodiment not only ensures the safe storage of important items such as keys but also meets the diverse needs of users for storing items of different sizes. Furthermore, the independently configured compartment door, electromagnetic lock, and RFID directional near-field antenna of the second storage compartment not only improves the security and inventory efficiency of the items but also reduces maintenance costs and simplifies user operation. Therefore, this application has broad promotional value and application prospects in practical applications and can meet the needs of different user groups.

[0097] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
