[0039] As shown in the figure, in one embodiment of the utility model, a locked storage box 100 includes a bottom box 10, an upper cover 20, a locking structure 30 and an unlocking device 40. One side edge of the upper cover 20 is rotatably connected to the bottom box 10. The upper cover 20 can rotate relative to the bottom box 10 to form two states. When the upper cover 20 rotates to cover the bottom box 10, a closed storage area is formed between the upper cover 20 and the bottom box 10; the upper cover 20 can also rotate to be flush with the bottom box 10, thereby opening the storage area for storing or taking out items. The inner side wall of the upper cover 20 is provided with a locking plate 21, and a lock port 211 is provided on the locking plate 21. The locking structure 30 includes a housing 31 and a first locking plate 32 and a second locking plate 33 arranged in the housing 31. The housing 31 can protect the internal transmission structure (the first locking plate 32, the second locking plate 33, the first connecting rod mechanism 42, and the second connecting rod mechanism 45), and a protrusion or groove can be provided on the housing 31 to limit the transmission structure or provide an installation basis. The shell 31 is connected to the bottom box 10, and the first locking piece 32 and the second locking piece 33 are both rotatably connected to the shell 31. The first end of the first locking piece 32 is provided with a locking hook 321, and the second end of the first locking piece 32 abuts against the second locking piece 33; a through hole 311 is provided on the top of the shell 31. When the upper cover 20 is rotated to cover the top of the bottom box 10, the locking piece 21 passes through the through hole 311 and the locking hook 321 extends into the locking port 211, thereby locking the upper cover 20 and the bottom box 10.

[0040] In the first example of this embodiment, the unlocking device 40 includes a mechanical unlocking member 41 and a first connecting rod mechanism 42. The mechanical unlocking member 41 is rotatably connected to the shell 31, one end of the first connecting rod mechanism 42 is transmission-connected to the mechanical unlocking member 41, and the other end of the first connecting rod mechanism 42 is connected to the second locking plate 33; the mechanical unlocking member 41 drives the second locking plate 33 to rotate through the first connecting rod mechanism 42 to rotate the first locking plate 32 until the lock hook 321 is disengaged from the lock port 211; the mechanical unlocking member 41 has a lock hole, and only the key that matches it can be inserted into the lock hole and drive the mechanical unlocking member 41 to rotate.

[0041] In the second example of this embodiment, the unlocking device 40 also includes an electronic unlocking component 43, a motor 44 and a second connecting rod mechanism 45. The electronic unlocking component 43 is arranged on the shell 31, and the electronic unlocking component 43 is communicated with the motor 44. One end of the second connecting rod mechanism 45 is connected to the output shaft of the motor 44, and the other end is connected to the second locking plate 33; the electronic unlocking component 43 can control the rotation of the motor 44, and drive the second locking plate 33 to rotate through the second connecting rod mechanism 45 to make the first locking plate 32 rotate until the lock hook 321 disengages from the lock mouth 211.

[0042] Among them, the electronic unlocking component 43 can be a password disk, fingerprint recognition module, camera and other unlocking methods known in the art. The specific form of the electronic unlocking component 43 in this application is not limited. It only needs to control the motor 44 to rotate or stop according to the recognition result after the electronic unlocking component 43 is successfully recognized.

[0043] The first example and the second example can be used in combination with each other. The mechanical unlocking member 41 and the electronic unlocking member 43 drive the second locking plate 33 to rotate through different connecting rods, thereby realizing the unlocking action. In addition, the electronic unlocking member 43 can also be multiple, for example, it has both a password disk and a fingerprint recognition module. If one of the two is successfully recognized, the motor 44 can be controlled to rotate to realize unlocking. This embodiment combines multiple unlocking methods through two locking plates and two connecting rod structures, while simplifying the lock body structure.

[0044] It can be understood that the mechanical unlocking member 41 and the electronic unlocking member 43 can be arranged on the side of the shell 31 away from the bottom box 10, and the upper cover 20 is provided with an avoidance hole for the mechanical unlocking member 41 and the electronic unlocking member 43 to pass through and be exposed.

[0045] Based on the above embodiment, the locking structure 30 further includes a spring 34, one end of the spring 34 is connected to the second end of the first locking plate 32, the other end of the spring 34 is connected to the second locking plate 33, and the connection between the spring 34 and the second locking plate 33 is arranged near the bottom end of the second locking plate 33. When the upper cover 20 rotates to cover the top of the bottom box 10, the first locking plate 32 and the second locking plate 33 are engaged with each other, and the spring 34 can be pre-stretched a certain distance, so as to pull the second end of the first locking plate 32 and the bottom end of the second locking plate 33 to fit together. And during the unlocking action, the second locking plate 33 rotates to unlock with the first locking plate 32, and under the action of the spring 34, slides along the left edge of the second locking plate 33 until the lock hook 321 is separated from the lock port 211 to achieve unlocking.

[0046] It can be understood that the lockable storage box 100 further includes a reset member, which can drive the second locking piece 33 and the first locking piece 32 to return to a mutually engaged state. The reset member can be a torsion spring, which can be installed at the rotation connection between the first locking piece 32 / the second locking piece 33 and the housing 31. The torsion spring provides an initial force for the first locking piece 32 or the second locking piece 33 to return to a mutually engaged state in the unlocked state, and the spring 34 also plays an auxiliary role in the process of returning to the mutually engaged state. Of course, the reset member can also be in other forms, which is not limited in this application.

[0047] Specifically, the second end of the first locking piece 32 is provided with a butt joint 322 protruding toward the second locking piece 33, and the second locking piece 33 forms a slot 331 and a guide slot 332 on one side edge facing the first locking piece 32, and the slot 331 and the guide slot 332 have a smooth transition. As shown in the figure, the second locking piece 33 is located on the right side of the first locking piece 32, and the butt joint 322 is provided on the lower right side of the first locking piece 32, and the left side edge of the second locking piece 33 has a slot 331 and a guide slot 332. When the upper cover 20 rotates to cover the top of the bottom box 10, the butt joint 322 is inserted into the slot 331. During the unlocking process, the second locking piece 33 rotates counterclockwise, and the butt joint 322 is separated from the slot 331. Under the action of the spring 34, the butt joint 322 can slide along the guide slot 332, so that the movement process of the first locking piece 32 is more stable.

[0048] In some other embodiments, the guide groove 332 is directly free, and during the unlocking process, the first locking piece 32 and the second locking piece 33 are spaced apart and rotate under the action of the spring 34 until the locking hook 321 is disengaged from the latch.

[0049] The top edge of the lock hook 321 forms an arc edge 323. When the first lock piece 32 and the second lock piece 33 are engaged, the upper cover 20 rotates to cause the locking piece 21 to be transmitted from the through hole 311. At this time, the locking piece 21 contacts the arc edge 323 on the lock hook 321. For example, the arc edge 323 is formed at the right end of the top edge. The locking piece 21 contacts the arc edge 323 and continues to press down. The force of the locking piece 21 on the arc edge 323 has a component force that pushes the first lock piece 32 to rotate counterclockwise, so that the locking piece 21 can continue to slide down until the lock hook 321 is facing the lock port 211. At this time, the locking piece 21 is no longer in contact with the arc edge 323. Under the action of the reset member, the first lock piece 32 rotates clockwise to drive the lock hook 321 to insert into the lock port 211.

[0050] In some embodiments, the first linkage mechanism 42 includes a first linkage 421 and a second linkage 422, the second linkage 422 includes a first connecting arm 4221 and a second connecting arm 4222 connected at an angle, the connection between the first connecting arm 4221 and the second connecting arm 4222 is rotatably connected to the shell 31, and a first guide groove 4223 is provided on the first connecting arm 4221; a first rotating shaft 4211 is provided at one end of the first linkage 421, and the first rotating shaft 4211 is movably provided in the first guide groove 4223, the other end of the first linkage 421 is rotatably connected to the end of the first connecting arm 4221, and the second connecting arm 4222 is pressed against the top of the second locking plate 33 toward the side of the mechanical unlocking member 41. The first connecting rod 421 rotates with the mechanical unlocking member 41, and the end of the first connecting rod 421 swings around the mechanical unlocking member 41, and contacts the groove wall of the first guide groove 4223 during the swinging process, thereby pushing the first connecting arm 4221 to rotate during the sliding process along the guide groove, thereby driving the second connecting arm 4222 to rotate, and the second connecting arm 4222 is pressed against the top of the second locking plate 33 during the rotation process, pushing the second locking plate 33 to rotate counterclockwise. The second connecting rod 422 plays a role of switching, converting the horizontal rotation into the rotation on the vertical plane, making full use of the internal space of the shell 31.

[0051] In other embodiments, if space permits, the first connecting rod mechanism 42 may only include the first connecting rod, and the first connecting rod directly drives the second locking piece 33 .

The adapter sleeve 451 includes a sleeve portion 4511 and a third connecting arm 4512 extending radially outward from the side wall of the sleeve portion 4511. The sleeve portion 4511 is connected to the output shaft of the motor 44. The third link 452 is rotatably connected to the third connecting arm 4512. A second guide groove 4521 is provided at one end of the third link 452. A second rotating shaft 333 is provided near the bottom end of the second locking plate 33. The second rotating shaft 333 is movably arranged in the second guide groove 4521. The first link mechanism 42 acts on the top of the second locking plate 33, and the second link mechanism 45 acts on the bottom end of the second locking plate 33. The first link mechanism 42 is distributed at the top of the space in the housing 31, and the second link mechanism 45 is distributed at the bottom of the space in the housing 31, so as to make full use of the internal space of the housing 31.

[0053] Based on the above embodiment, the other end of the third connecting rod 452 forms a sensing piece 4522, and the locked storage box 100 further includes a sensor 5, which is disposed on the housing 31, and the sensor 5 is connected to the motor 44 by signal, and the sensor 5 is used to detect the position of the sensing piece 4522. The sensor 5 can detect that the sensing piece 4522 is in place, and it can be determined that the lock hook 321 of the first locking piece 32 has been separated from the lock port 211, so as to facilitate the determination of whether the upper cover 20 is rotated in place and unlocked. The sensor 5 can be a through-beam sensor 5 or a distance sensor 5.

[0054] In some embodiments, the lockable storage box 100 also includes a hinge mechanism 6, which includes an adapter plate 61 and a first pivot 62 and a second pivot 63 that are rotatably connected. The upper cover 20 is connected to the first pivot 62 through the adapter plate 61, and the bottom box 10 is connected to the second pivot 63, thereby realizing a rotatable connection between the upper cover 20 and the bottom box 10.

[0055] Among them, the adapter plate 61 includes a first connecting part, an extension part and a second connecting part which are connected in sequence. The first connecting part is connected to the upper cover 20, and the second connecting part is connected to the first pivot 62. The extension part includes two sections arranged at right angles. The extension part can avoid the edge of the bottom box 10 and increase the distance between the upper cover 20 and the first pivot 62, so that the upper cover 20 can be rotated to be flush with the bottom box 10.

[0056] In some embodiments, a protective layer 71 may be provided on the inner side of the upper cover 20 and the inner side of the bottom box 10 . The protective layer 71 may be a flexible filling material, such as foam, to flexibly support and protect items stored in the lockable storage box 100 .

[0057] In some embodiments, the bottom box 10 is connected to at least two opposite sides with baffles 72, the top of the baffles 72 is tilted inward to form a guide surface 721, and when the upper cover 20 is rotated to cover the top of the bottom box 10, the baffles 72 are located in the gap between the upper cover 20 and the bottom box 10, thereby protecting the items stored in the locked storage box 100.
