[0064] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all the structures.

[0065] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0066] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them.

The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0067] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0068] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0069] As Figures 1 to 11 shown, this embodiment provides a precious metal protection device for storing precious metals. The device includes a protection box 1, an unlocking structure 2 and a reset structure 3. The protection box 1 includes a box body 11 and a box door 12. The box body 11 is surrounded by a storage chamber, and the precious metals are placed in the storage chamber. The box door 12 is rotatably arranged on the box body 11. The box door 12 has a locked state in which it blocks the storage chamber and is locked to the box body 11 and an open state in which it is separated from the storage chamber. The unlocking structure 2 includes a processor 21 and a magnetic key. A working chamber 110 is opened on the box body 11. The processor 21 is arranged in the working chamber 110 for identifying the magnetic key, and the magnetic key can extend into the working chamber 110. After the magnetic key extends into the working chamber 110, the processor 21 performs identification and verification on the magnetic key. If the magnetic code and magnetic field strength of the magnetic key match the information in the processor 21, the box door 12 can be switched to the open state, that is, the box door 12 can be opened. The reset structure 3 is arranged in the working chamber 110 and includes a monitoring component 31 and a regulator 32. The monitoring component 31 is used for monitoring the position information of the magnetic key and the speed at which the magnetic key enters the working chamber 110. The regulator 32 is communicatively connected to the monitoring component 31 and is used for resetting and adjusting the password information of the magnetic key. The reset and adjusted password information of the magnetic key is stored in the processor 21.

[0070] That is to say, every time the magnetic key enters the working chamber 110, the password information of the magnetic key will be reset and adjusted by the regulator 32 once, and each adjusted password information will be stored in the processor 21 for the next verification and matching of the magnetic key. The basis for resetting and adjusting the password information of the magnetic key is the position information of the magnetic key and the speed at which the magnetic key enters the working chamber 110. Since the speed at which the magnetic key enters the working chamber 110 and the position in the working chamber 110 are highly random, this results in the password information of the magnetic key being highly random each time, enhancing the unpredictability of the password information based on physical randomness. That is, it has the characteristic of "one-time one password" to improve the security of the protection device and effectively prevent the loss of precious metals.

[0071] Specifically, a cryptographically secure pseudorandom number generator (CSPRNG) is provided in the regulator 32 to ensure the randomness of the reset password information.

[0072] Meanwhile, when the reset password information is stored in the processor 21, the processor 21 will compare the reset password information with the previously used password information to avoid duplication with the previously used password information. If it duplicates with the historical password information, the regulator 32 will reset the password information of the magnetic key again. Specifically, multiple programs for resetting password information are set in the regulator 32. Inputting the same initial data, different programs will generate different password information.

[0073] In addition, a unique identification code (UID) can be embedded in the magnetic key and bound to the processor 21 to make the magnetic key unique.

[0074] Specifically, as Figure 7 shown, the unlocking structure 2 further includes an induction coil 22. The induction coil 22 is communicatively connected to the processor 21. Meanwhile, an insertion slot 23 for inserting the magnetic key is provided in the working chamber 110. The induction coil 22 is located on one side of the insertion slot 23 and is used to sense and identify the password information in the magnetic key. The password information includes magnetic encoding, magnetic field strength and other password information. The password information identified by the induction coil 22 can be transmitted into the processor 21. The processor 21 matches and verifies the identified password information with the password information stored in the processor 21 itself. If they are consistent, the box door 12 can be opened to adjust the box door 12 to the open state. In addition, in this embodiment, the regulator 32 can reset and adjust the magnetic field strength and / or magnetic encoding of the magnetic key.

[0075] More specifically, a telescopic frame is provided between the induction coil 22 and the inner wall of the working chamber 110. When the regulator 32 resets the password information of the magnetic key, the telescopic frame will drive the induction coil 22 as far away from the regulator 32 as possible to avoid the induction coil 22 interfering with the regulator 32.

[0076] In addition, the state switching of the box door 12 can be controlled by magnetic elements. Its control structure and principle refer to the prior art and will not be elaborated here.

[0077] Exemplarily, the processor 21, the induction coil 22, the regulator 32, etc. are all existing devices. Their specific structures and principles refer to the prior art and will not be elaborated here.

[0078] It should be noted that when the protection device is used for the first time, the magnetic key has an initial password information, and this initial password information is recorded in the processor 21.

[0079] Further, the monitoring component 31 includes a height monitoring sensor 311 and a plurality of monitoring coils 312. The height monitoring sensor 311 is used to monitor the height of the magnetic key within the working chamber 110; the plurality of magnetic coils are arranged at equal intervals along the extending direction of the working chamber 110 and are used to monitor the speed at which the magnetic key enters the working chamber 110. When the magnetic key enters the working chamber 110, it sequentially passes through the plurality of monitoring coils 312 and simultaneously triggers the plurality of monitoring coils 312. Moreover, since the plurality of monitoring coils 312 are arranged at equal intervals, the speed at which the magnetic key enters the working chamber 110 can be monitored. Additionally, multiple height monitoring sensors 311 may also be provided, and the average value of the height values measured by the multiple height monitoring sensors 311 is taken as the final height value. Exemplarily, the height monitoring sensor 311 and the monitoring coils 312 are also existing devices and will not be elaborated herein.

[0080] Furthermore, the monitoring component 31 further includes a time monitor (not shown in the figure). The time monitor can record the usage time of the magnetic key. On the basis that the regulator 32 uses the speed at which the magnetic key enters the working chamber 110 and the height of the magnetic key within the working chamber 110 as the basis for resetting the password information, it can also combine the time information to reset the password information of the magnetic key, further enhancing the randomness of the password information of the magnetic key. Specifically, the time monitor is an existing device, and its specific structure and principle refer to the prior art and will not be elaborated herein.

[0081] Optionally, a trigger cylinder 313 is provided at the front end of the working chamber 110. Referring to Figure 4 , the trigger cylinder 313 is provided with a trigger chamber 3130, and both the height monitoring sensor 311 and the monitoring coils 312 are arranged within the trigger chamber 3130. The above arrangement can provide protection for the height monitoring sensor 311 and the monitoring coils 312, which is beneficial to extending the service life. Specifically, the trigger cylinder 313 is further surrounded by a card reading chamber 314, and the magnetic key will pass through the card reading chamber 314 before being inserted into the card slot 23.

[0082] Optionally, a storage battery 6 is further provided within the working chamber 110. The storage battery 6 is connected to the induction coil 22 and the regulator 32 and is used to supply power to the induction coil 22 and the regulator 32 to ensure their normal operation.

[0083] Optionally, the box body 11 includes an inner shell and an outer shell. The outer shell covers the inner shell. The storage chamber is surrounded by the inner shell, and a gas chamber 111 is surrounded between the inner shell and the outer shell. With the above arrangement, since the storage of precious metals has certain environmental requirements, even if the outer shell is damaged, it will not affect the storage of precious metals within the storage chamber.

[0084] The precious metal protection device further includes an anti-theft structure 4. The anti-theft structure 4 includes an alarm 41 and a first anti-theft component 42. The first anti-theft component 42 includes a barometric pressure monitoring component, which is used to monitor the barometric pressure value in the gas chamber 111. When the box body 11 is damaged by the outside world and the outer shell is damaged, the gas in the gas chamber 111 leaks, resulting in a decrease in the barometric pressure value in the gas chamber 111. The barometric pressure value monitored by the barometric pressure monitoring component is transmitted to the processor 21. When the processor 21 detects a fluctuating change in the barometric pressure value, it will control the alarm 41 to send an alarm signal to remind the staff to confirm the safety of the device in time. Exemplarily, the alarms 41 are all existing devices, and their specific structures and principles refer to the prior art, which will not be elaborated here.

[0085] Specifically, in this embodiment, referring to Figure 8 , the barometric pressure monitoring component includes a barometric cylinder 421, a barometric tube 422, an elastic membrane 423 and a strain gauge 424. The barometric cylinder 421 is arranged in the working chamber 110. The barometric tube 422 is communicated between the gas chamber 111 and the barometric cylinder 421. The elastic membrane 423 is arranged on the top of the barometric cylinder 421, and the strain gauge 424 is fixedly installed on the elastic membrane 423. When the barometric pressure in the gas chamber 111 decreases, the pressure values in the barometric tube 422 and the barometric cylinder 421 decrease synchronously, resulting in a decrease in the curvature of the elastic membrane 423. Furthermore, the value detected by the strain gauge 424 also decreases. The strain gauge 424 transmits the signal to the processor 21, and the processor 21 activates the alarm 41. In addition, the barometric cylinder 421 is provided with a barometric nozzle 425, which is used for connecting to the output end of the inflation mechanism to facilitate inflation and pressure boosting in the gas chamber 111. The type of gas in the gas chamber 111 can be selected as required and will not be specifically limited here.

[0086] Alternatively, in other embodiments, the barometric pressure monitoring component can also be a barometric pressure monitoring sensor, which directly monitors the barometric pressure value in the gas chamber 111.

[0087] Furthermore, referring to Figure 3 and Figure 5 , an installation chamber 120 is provided at the edge of the box door 12. The anti-theft structure 4 further includes a second anti-theft component 43. The second anti-theft component 43 includes a first alarm coil 431 and a magnetic column 432. The first alarm coil 431 and the magnetic column 432 are respectively arranged on the opposite inner walls of the installation chamber 120, and the first alarm coil 431 is connected to the processor 21. When the edge of the box door 12 is pried, it will force the inner wall of the installation chamber 120 to move, and then drive the magnetic column 432 to extend into the first alarm coil 431. After the first alarm coil 431 detects the entry of the magnetic column 432, it will transmit a signal to the processor 21, and the processor 21 will then control the activation of the alarm 41 to send an alarm signal to remind the staff.

[0088] Further, a plurality of second anti-theft components 43 are spaced apart. When the edge on either side of the box door 12 is pried, the alarm 41 can emit an alarm signal, further improving the timeliness and accuracy of the alarm and enhancing the security of precious metals.

[0089] Specifically, in this embodiment, with continued reference to Figure 5 , a pressing plate 433 and a second elastic member 434 are disposed in the installation chamber 120. The pressing plate 433 is slidably disposed in the installation chamber 120 and is located on the side close to the edge of the box door 12. One of the first alarm coil 431 and the magnetic post 432 is disposed on the pressing plate 433, and the other is disposed on the inner wall of the installation chamber 120 opposite to the pressing plate 433. When the box door 12 is pried, the pressing plate 433 will be displaced. At the same time, a second elastic member 434 is connected between the pressing plate 433 and the inner wall of the installation chamber 120. Under the elastic action of the second elastic member 434, the displaced pressing plate 433 can be driven to reset in time. Exemplarily, the second elastic member 434 is a commonly used spring. Alternatively, in other embodiments, the pressing plate 433 and the second elastic member 434 may not be provided, and the first alarm coil 431 and the magnetic post 432 may be directly disposed on two opposite inner walls of the installation chamber 120.

[0090] Optionally, a lock hole 121 is provided on the box door 12, and a lock rod 112 is provided on the box body 11. In the locked state, the lock rod 112 is inserted into the lock hole 121; in the open state, the lock rod 112 is separated from the lock hole 121. The precious metal protection device further includes a transmission structure 5. With reference to Figure 3 , the transmission structure 5 includes a driving mechanism 51 and a transmission component 52. The driving mechanism 51 is disposed in the working chamber 110, and the transmission component 52 is disposed between the output end of the driving mechanism 51 and the lock rod 112 for driving the lock rod 112 to be inserted into or separated from the lock hole 121. The state switching of the lock rod 112 is transmitted by a mechanical structure, which has high reliability and durability, and is easy to maintain and has low cost. Exemplarily, the driving mechanism 51 is a commonly used motor in the art.

[0091] Further, with reference to Figure 3 , Figure 9 and Figure 10, the transmission assembly 52 includes a first bevel gear 521, a first transmission rod 522, a second bevel gear 523, a third bevel gear 524, a second transmission rod 525, a fourth bevel gear 526, a first gear 527 and a first toothed plate 528. The first bevel gear 521 is arranged at the output end of the driving mechanism 51. The first transmission rod 522 extends in the vertical direction, with the first end located in the working chamber 110 and the second end located in the transmission chamber 113. The second bevel gear 523 is arranged at the first end of the first transmission rod 522 and meshes with the first bevel gear 521. The third bevel gear 524 is arranged at the second end of the first transmission rod 522. The second transmission rod 525 extends in the first horizontal direction and is arranged in the transmission chamber 113. The fourth bevel gear 526 is arranged at the first end of the second transmission rod 525 and meshes with the third bevel gear 524. The first gear 527 is arranged at the second end of the second transmission rod 525. The first toothed plate 528 is movably arranged in the transmission chamber 113 along the second horizontal direction and meshes with the first gear 527. The first horizontal direction is perpendicular to the second horizontal direction. A first moving plate 114 is arranged in the transmission chamber 113. The locking rod 112 is arranged on the first moving plate 114 and passes through the transmission chamber 113. The first toothed plate 528 is arranged on the first moving plate 114. Driven by the driving mechanism 51, the first toothed plate 528 can move in the transmission chamber 113 along the second horizontal direction, thereby driving the movement of the locking rod 112, so that the locking rod 112 is inserted into or separated from the locking hole 121, realizing the locking or opening of the box door 12. The above arrangement can make reasonable use of the space of the box body 11 and the transmission is stable and reliable.

[0092] Specifically, in this embodiment, in combination with Figure 4 and Figure 5 , a sliding groove 117 is arranged in the transmission chamber 113. The first moving plate 114 is slidably arranged in the sliding groove 117 along the second horizontal direction to ensure the accuracy of the moving direction of the first moving plate 114. In addition, a plurality of locking rods 112 are arranged on the first moving plate 114. Correspondingly, a plurality of locking holes 121 are formed in the box body 11, and the locking holes 121 correspond to the locking rods 112 one by one.

[0093] More specifically, first limiting portions 1141 are arranged at both ends of the first moving plate 114, and two limiting grooves 1171 are correspondingly arranged at both ends of the sliding groove 117 to limit the first moving plate 114 from moving vertically and ensure the accuracy of its moving direction along the second horizontal direction.

[0094] Furthermore, a first elastic member 115 is connected between the first moving plate 114 and the inner wall of the transmission chamber 113. The above arrangement avoids the first moving plate 114 from moving under external disturbances and improves the stability of the locking rod 112 in the locking hole 121 in the locked state. Exemplarily, the first elastic member 115 is a commonly used spring.
