[0038] In order to make the purpose, technical scheme and effect of the utility model more clear and definite, the utility model is further described in detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.
[0039] It should be noted that the terms "first", "second" and the like in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a system, product or device including a series of units does not have to be limited to those clearly listed, but can include other units not clearly listed or inherent to these products or devices.
[0040] Reference Figures 1-6 As shown in the drawings, the embodiment provides a kind of intelligent key holder, including key holder 1 and key holder storage unit 2.
[0041] The key holder 1, first through hole 11 and accommodation portion 13 are arranged on it.The first through hole 11, through the thickness direction of the key holder 1.The accommodation portion 13 is located in the front end (i.e. insertion end) of the key holder 1, and the IC card 14 is embedded in the accommodation portion 13, and the IC card serial number is key identification module.
[0042] 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 that communicates with the socket 211. The socket 211 is for the keychain 1 to be inserted into the cavity. The cavity is provided with a clamping hook 212. When the front end of the keychain 1 is inserted into the cavity, the clamping hook 212 is in movable connection with the first through hole 11 to lock or release the clamping hook 212 from the first through hole 11. The antenna control board 22 is installed in the cavity of the keychain socket 21. The antenna control board 22 is integrated with a card reading module and an antenna. The antenna communicates wirelessly with the IC card 14 of the keychain 1 to read the serial number of the IC card, 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, which simplifies the structure and improves the reliability and performance. Because the antenna and the card reading module are closely integrated, 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 smaller in size, easier to install and carry.
[0043] As understood by those skilled in the art, the antenna can also not be integrated in the antenna control board 22, but as a separate component adjacent to the antenna control board 22. Specifically, as shown in one embodiment, Figure 1 the antenna 23 and the antenna control board 22 are separate. When the keychain 1 is inserted into the keychain socket 21, the antenna 23 is located between the accommodation portion 13 of the keychain 1 and the antenna control board 22, i.e. the antenna 23 is physically 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 accommodation portion 13 through the antenna 23.
[0044] Specifically, referring to Figure 2 a structural schematic diagram of a keychain 1 is shown. The keychain 1 has flat upper and lower surfaces and smooth side edges. Of course, the keychain 1 is not limited to the shape shown. The accommodation portion 13 includes a circular groove on the keychain 1 and a circular end cover 15 sealing the opening of the circular groove, and the IC card 14 is attached in the accommodation portion 13. The circular end cover 15 is not detachably connected to the circular groove, such as by ultrasonic welding technology to connect the circular end cover 15 to the circular groove, so that the IC card 14 cannot be removed without damaging the structure. This design can prevent the IC card 14 from being misused.
[0045] 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.
[0046] 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 (i.e. the insertion end) of the key ring 1 is inserted into the internal cavity of the key ring socket 21, it will first apply pressure to the locking protrusion. When the front end of the key ring 1 continues to be inserted, the locking protrusion of the hook 212 is locked into the first through hole 11 of the key ring 1, and is in a locked state without the need for external force assistance.
[0047] In this embodiment, the keychain socket 21 has a through-type light groove 213 on its 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 keychain 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 keychain 1 is inserted into 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 keychain 1 has been correctly inserted, so that the user can quickly confirm the connection status between the keychain 1 and the keychain socket 21.
[0048] In a preferred embodiment, the key ring socket 21 is made of PC material. PC material has a certain degree of flexibility and elasticity, and the hook 212 can be slightly deformed to adapt to the insertion and removal process, thereby enabling repeated insertion and removal without easy damage.
[0049] In enterprises and institutions, key management involves multiple links, such as key access, key storage and inventory. If the existing intelligent key buckle technology is used, such as managing the weight of a single key buckle connected key by weighing the weight of the key, it cannot effectively monitor the access and inventory process of the key, and cannot guarantee the safety of the key. When the key is taken away and replaced, the technology cannot provide effective management means. For example, voice recognition and a loudspeaker are provided inside the intelligent key buckle, and the lost key is found by shouting in the form of artificial shouting. However, when multiple key buckles are placed together, it is not possible to distinguish which key buckle responded to the shouting, so it is not possible to accurately identify which key buckle corresponding to the lost key. For example, by providing a positioning device and a signal transceiver device inside the intelligent key buckle, the distance between the key buckle and the handheld terminal is sensed, and when the distance exceeds the preset range, an alarm and a location prompt are provided to avoid key loss and facilitate key search. However, such a key buckle not only has high cost, but also lacks an effective identification mechanism when managing multiple key buckles, and cannot accurately manage the process of key buckle taking, returning and inventory.
[0050] In summary, the intelligent key buckle of the present embodiment binds a large number of keys and intelligent key buckles in enterprises and institutions, realizes intelligent, information-based and systematic management of key storage, taking, storage and inventory in enterprises and institutions, and guarantees the information-based, standardized and secure management of keys in enterprises and institutions. Therefore, the present application has wide application value and application prospect in practical application, and can meet the diversified needs of different user groups.
[0051] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
