Description

Technical Field

[0001] The present invention relates to the technical field of article management, and in particular to an important article safe deposit box and a management method thereof. Background Art

[0002] As a special item, keys play an important role in enterprises and institutions. Once keys are stolen or lost due to negligence in management, it will bring great security risks or significant losses. However, the materials and shapes of keys vary greatly, and it is very difficult to achieve direct information management of the key body. With the help of standardized smart key chains to achieve key management, it is very effective and convenient.

[0003] In the prior art, there are various ways to manage smart key chains. Some of them determine whether the key is lost by detecting the weight change of the key hanging on the key chain, but this method faces many challenges in practical application. For example, when the key chain and the key are connected and put into a pocket or bag, the key and the key chain will inevitably collide and rub during walking, resulting in the inability to accurately measure the weight of the key, making this method difficult to apply in practice.

[0004] Another type of smart key fob attempts to find lost keys by manually shouting, by setting up devices such as voice recognition and speakers inside. However, when multiple key fobs are placed together, it is impossible to accurately distinguish which key fob responded to the shouting, so it is impossible to determine which key fob is lost.

[0005] In addition, there is also a smart key fob that has a positioning device and a signal transceiver inside it, which can sense the distance change between the key fob and the handheld terminal. When the distance exceeds the preset range, the key fob will issue an alarm and location prompt to prevent key loss and facilitate key retrieval. However, this key fob is not only expensive, but also exposes obvious defects in the multi-key fob management scenario. Due to the lack of an identification device, the key fob cannot achieve accurate and effective management when handling management tasks such as key fob collection, return, and regular inventory.

[0006] In view of the shortcomings of the above technologies, important items safe deposit boxes (specifically referring to smart key cabinets with integrated intelligent management functions) came into being. This type of safe deposit box concentrates smart key chains into one smart cabinet, aiming to manage smart key chains in a safe, digital and intelligent manner.

[0007] In addition, most existing technologies only manage keys, which does not fully meet the integrated storage and management needs of enterprises and institutions for diversified items.

[0096] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0097] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, but not necessarily to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a system, product or device containing a series of units is not necessarily limited to those units clearly listed, but may include other units that are not clearly listed or inherent to these products or devices.

[0098] Example 1

[0099] like Fig. 9 As shown, this embodiment provides an important item storage cabinet, including a cabinet body 4, wherein the cabinet body 4 includes at least one 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 arranged in rows in the horizontal direction, arranged in columns in the vertical direction, or arranged in an array in the horizontal and vertical directions.

[0100] One or more first storage compartments 3 in an important item safe deposit box work together through a unified connection interface and control system. Each first storage compartment 3 is equipped with an independent antenna control board to achieve self-circuit control and independent work, which enables the main control system of the important item safe deposit box to manage and control each first storage compartment 3 more efficiently.

[0101] 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 chain.

[0102] The storage body 31 is provided with a receiving cavity for storing the key chain.

[0103] The warehouse door 32 closes the opening of the warehouse body 31 through an electromagnetic lock 313. The warehouse door 32 can be opened only under authorized operation (such as through identity authentication methods such as passwords, fingerprints, etc.), and an observation window is provided on the warehouse door 32.

[0104] Among them, smart key fob, see Figure 1-Figure 6 As shown, it specifically includes two parts: a key chain 1 and a key chain storage unit 2.

[0105] The key chain 1 is provided with a first through hole 11 and a receiving portion 13. The first through hole 11 runs through the thickness direction of the key chain 1. The receiving portion 13 is located at the front end (i.e., the insertion end) of the key chain 1, and an IC card 14 is embedded in the receiving portion 13, and the serial number of the IC card is the key identification code.

[0106] The keychain storage unit 2 includes a keychain socket 21 and an antenna control board 22. The keychain socket 21 includes a panel with a socket 211 and a cavity connected to the socket 211. The socket 211 is for the keychain 1 to be inserted into the cavity. A hook 212 is provided in the cavity. When the front end of the keychain 1 is inserted into the cavity, the hook 212 is movably engaged with the first through hole 11, so that the hook 212 is locked in the first through hole 11 or released from the first through hole 11. The antenna control board 22 is installed in the cavity of the keychain socket 21, wherein a card reading module and an antenna are integrated on the antenna control board 22, and wireless communication with the IC card 14 of the keychain 1 is performed through the antenna to read the IC card serial number, which can be recorded as the identification code of the keychain 1 in the key cabinet management system. The antenna is integrated on the antenna control board 22, and this design not only simplifies the structure, but also improves reliability and performance. Since the antenna is tightly integrated with the card reader module, the signal transmission between them is more direct and efficient, reducing signal loss and interference, thereby improving the card reading speed and accuracy. In addition, the integrated design reduces the number of external connection lines and interfaces, reduces the risk of failure, improves the overall stability and durability, and makes the keychain storage unit 2 more compact, easy to install and carry.

[0107] Those skilled in the art will appreciate that the antenna may not be integrated into the antenna control board 22, but may be provided as an independent component separate from and adjacent to the antenna control board 22. Figure 1 In one embodiment shown, the antenna 23 and the antenna control board 22 are separately arranged. When the key chain 1 is inserted into the key chain socket 21, the antenna 23 is located between the accommodating portion 13 of the key chain 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 with the IC card in the accommodating portion 13 through the antenna 23.

[0108] For details, see Figure 2 A schematic diagram of the structure of a key chain is shown, the key chain 1 has a flat upper surface and a lower surface, and the side edges are smoothly transitioned. Of course, the key chain 1 is not limited to the shape shown in the figure. The accommodating portion 13 includes a circular groove provided on the key chain 1, and a circular end cover 15 that seals the opening of the circular groove, and the IC card 14 is adhered to the accommodating portion 13. The circular end cover 15 is non-detachably connected to the circular groove, such as connecting the circular end cover 15 to the circular groove by ultrasonic welding technology, so that the IC card 14 cannot be taken out without destroying the structure. This design can prevent the IC card 14 from being stolen.

[0109] In a preferred embodiment, the rear end of the key chain 1 is further provided with a second through hole 12, on which a key mounting structure 16 (such as Figure 3 As shown). The key mounting structure 16 is a detachable key ring, or it can be non-detachable. When a non-detachable key mounting structure 16 is used, once the key mounting structure 16 is damaged, it means that the key on the key ring 1 may have been illegally stolen. In this way, the security uniqueness and reliability between the key ring and the connected key can be guaranteed.

[0110] See also Figure 4-Figure 5 The schematic diagram of the structure of a key ring storage unit is shown, the hook 212 has a fixed end and a free end, the fixed end is fixedly installed in the cavity of the key ring socket 21, the free end faces the socket 211 and has a snap-on protrusion, and the snap-on protrusion includes an arc-shaped protrusion end or a triangular protrusion end. Figure 6 As shown, when the front end (i.e., the insertion end) of the key chain 1 is inserted into the internal cavity of the key chain socket 21, a pressure will be applied to the engaging protrusion first. When the front end of the key chain 1 continues to be inserted and the engaging protrusion of the hook 212 is engaged with the first through hole 11 of the key chain 1, it is in an engaged state and does not require external force assistance. In this embodiment, a through-type light groove 213 is provided on the panel of the key chain socket 21 with the plug 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 chain socket 21 to form an open 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 chain 1 is inserted into the 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, prompting the user that the key chain 1 has been correctly inserted, so that the user can quickly confirm the connection status between the key chain 1 and the key chain socket 21.

[0111] In a preferred embodiment, the keychain socket 21 is made of PC material. PC material has certain flexibility and elasticity, and the hook 212 can be slightly deformed to adapt to the plugging and unplugging process, thereby achieving multiple plugging and unplugging without being easily damaged. Figure 7 As shown, in this embodiment, a mounting hole 311 is opened on the back panel of the warehouse body 31, and the smart key chain socket 21 is installed on the outer side of the back panel (i.e., the side away from the interior of the warehouse body 31), and the socket 211 on the panel of the key chain socket 21 is opposite to the mounting hole 311 of the back panel.

[0112] In addition to the installation hole 311 reserved for the smart key chain storage unit 2, the back plate of the housing 31 is also provided with an indicator light hole 312, and the indicator light 221 of the key chain socket 21 faces the indicator light hole 312 of the back plate. When the key chain 1 is inserted into place, the light of the indicator light 221 on the key chain storage unit 2 can be transmitted through the indicator light hole 312 on the back plate, providing intuitive visual feedback to the user.

[0113] When the user needs to store the key, he only needs to connect the key to the key mounting structure 16 of the key chain 1, and then insert the key chain 1 into the insertion hole 211 of the key chain socket 21 through the mounting hole 311 on the back plate. When taking out the key, the user needs to first open the compartment door 32 through the authorized operation of the electromagnetic lock 313, and then pull out the key chain 1 to obtain the key.

[0114] In an actual application scenario, the first storage compartment 3 of the present embodiment can be used as a modular unit so as to be spliced ​​and combined as an independent storage module in the important item safe, making the important item safe more flexible and convenient when expanding functions, increasing storage capacity or adjusting layout. Users can change the number and layout of the first storage compartment 3 at any time according to actual needs to meet the application of important item safes of different scales and needs without replacing the entire important item safe.

[0115] like Figure 8 As shown, the two first accommodating compartments 3 can also be tightly spliced ​​together through a specific connection structure (such as buckles, bolts, etc.) to form a larger storage module.

[0116] It is understandable that, in actual applications, users can select different numbers of first storage compartments 3 to be combined with existing item storage cabinets according to actual needs, so as to meet the needs of item management of different scales and functions.

[0117] In enterprises and institutions, key management involves multiple links, such as key storage and access, key storage and inventory. If the existing smart key fob technology is used, such as managing by weighing the weight of the keys connected to a single key fob, it is impossible to effectively monitor the key storage and inventory process, and it is also impossible to ensure the safety of the keys. When the keys are taken away and replaced, this technology cannot provide effective management means. For example, voice recognition and speakers are set inside the smart key fob to find the lost keys through manual shouting. However, when multiple key fobs are placed together, it is impossible to accurately identify which key fob has lost the corresponding key because it is impossible to distinguish which key fob has responded to the shouting. For example, by setting a positioning device and a signal transceiver inside the smart key fob to sense the distance between the key fob and the handheld terminal, when the distance exceeds the preset range, there are alarm prompts and location prompts to avoid key loss and facilitate key finding. However, this key fob is not only costly, but also when managing multiple key fobs, due to the lack of an effective identification mechanism, it is impossible to accurately manage the key fob collection, return and inventory processes.

[0118] In summary, the smart key chain of the present embodiment includes a key chain and a key chain storage unit. By embedding an IC card in the key chain and using the card reader module in the key chain storage unit to communicate wirelessly with the antenna, the IC card serial number is read as the key identification code. When the key chain is plugged into the key chain socket, the two can be aligned and plugged in. The snap-in protrusion can automatically snap into the first through hole, and the operation is convenient and quick.
