[0030] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0031] like Figure 1 and Figure 2 As shown, the safe deposit box comprises a box body 1 and a box cover 2 installed on the box body 1 at one side through a pop-up mechanism 3; the box body 1 is formed by a box bottom plate 11 and a plurality of side plates 12, a locking mechanism and an inner partition 13 for installing the locking mechanism are provided inside the box body 1, and the inner partition 13 divides the inside of the box body 1 into a storage cavity located on one side of the inner partition 13 and an installation cavity located on the other side of the inner partition 13, and the locking mechanism is fixed on the inner partition 13 and is located in the installation cavity; a top end of the inner partition 13 near the box cover 2 is provided with a locking mechanism and an inner partition 13 for installing the locking mechanism. There is a lock hole 131; a lock tongue 21 is provided on the side of the box cover 2 relative to the pop-up mechanism 3, and the lock tongue 21 has a locking groove so as to cooperate with the locking structure to form a locked state; when the box cover 2 is closed on the box body 1, that is, when the box cover 2 has not been popped open relative to the box body 1 under the action of the pop-up mechanism 3 to expose the storage cavity, the lock tongue 21 is inserted into the lock hole 131, and a locked state is formed by the locking structure and the locking groove of the lock tongue 21 so that the box cover 2 will not pop open under the action of the pop-up mechanism 3, thereby allowing the storage cavity to form a relatively private storage space.

[0032] The function of the pop-up mechanism 3 is to allow the box cover 2 to pop open relative to the box body 1 by the pop-up mechanism 3 when the lock tongue 21 is not locked by the locking structure, so that the user can take items into the storage cavity of the box body 1.

[0033] The pop-up mechanism 3 usually includes a pivot shaft that rotationally connects one side of the box cover 2 with one side of the box body 1 and a torsion spring sleeved and limited on the pivot shaft, and the torsion spring generates a pop-up force on the box cover 2 based on the limit of the pivot shaft.

[0034] Further integration Figure 3-Figure 5As shown, the locking mechanism includes: a first rotating shaft 41; a second rotating shaft 42, which is spaced apart from the first rotating shaft 41; a lock core member 5, which is rotatably connected to the first rotating shaft 41, so that based on the rotation of the first rotating shaft 41, the lock core member 5 includes a lock bolt 51 and a first connecting portion 52 located at two opposite sides of the first rotating shaft 41, and a triggering portion 53 located between the lock bolt 51 and the first connecting portion 52; a linkage member 6, which is rotatably connected to the second rotating shaft 42, and based on the rotation of the second rotating shaft 42, the linkage member 6 includes a linkage portion 61 and a second connecting portion 62 The linkage part 61 forms a side abutment with the touch part 53, so that the linkage part 6 is linked through the side abutment structure between the linkage part 61 and the touch part 53 when it rotates based on the second rotating shaft 42; the elastic member 7 (usually a spring) is connected between the first connecting part 52 and the second connecting part 62, and generates an elastic force that allows the lock core member 5 to rotate in the first direction around the first rotating shaft 41; the unlocking mechanism is connected to the second connecting part 62, and when the unlocking mechanism drives the linkage part 6 to rotate around the second rotating shaft 42 in the first direction, the lock core member 5 is rotated in the opposite second direction.

[0035] The lock core 5 and the linkage 6 are located on one side of the inner partition 13 so that the lock bolt is located on one side of the lock hole 131. When the box cover 2 is closed on the box body 1, the lock tongue 21 is located in the lock hole 131, so that the lock bolt 51 cooperates with the locking groove of the lock tongue 21 for locking.

[0036] The trigger portion 53 has a locking side surface 531 and an unlocking side surface 532 connected to the locking side surface 531 . When the locking mechanism is in the locked state, the linkage portion 61 forms a side abutment with the locking side surface 531 . When the locking mechanism is in the unlocked state, the linkage portion 61 forms a side abutment with the unlocking side surface 532 .

[0037] The locking mechanism has a locked state and an unlocked state: in the locked state, the end of the linkage portion 61 forms a side contact with the locking side surface 531 to generate a rotation of the linkage member 6 around the first rotation axis 41 in the first direction (for example, the first direction is Figure 5 The locking bolt 51 is inserted into the locking tongue 21 so that the locking tongue 21 cannot escape from the locking hole 131. At this time, the box cover 2 is locked on the box body 1 by the locking mechanism, which is conducive to the safe storage of the items in the storage cavity. When the linkage member 6 is driven to rotate in the first direction around the second rotating shaft 42 under the action of the unlocking mechanism, the end of the linkage portion 61 gradually slides from the locking side surface 531 into the unlocking side surface 532 to form a side abutment with the locking side surface 531. The linkage portion 61 pushes the lock core member 5 in the second direction (for example, the second direction is Figure 5 The lock bolt 51 is rotated in the counterclockwise direction to disengage the lock bolt 21. At this time, the box cover 2 is opened relative to the box body 1 under the action of the pop-up mechanism 3, so that the user can take items from the storage cavity.

[0038] In addition, the locking mechanism also includes a first limit plate 81 and a second limit plate 82 arranged opposite to the first limit plate 81. The two ends of the first rotating shaft 41 and the second rotating shaft 42 are respectively pivotally connected to the first limit plate 81 and the second limit plate 82, and the lock core component 5 and the linkage component 6 are at least partially located between the first limit plate 81 and the second limit plate 82.

[0039] The first limiting plate 81 and the second limiting plate 82 limit the lock core 5 and the linkage 6 from two opposite sides, so that the linkage part 61 and the actuating part 53 can maintain reliable side contact and will not separate during the operation, thereby improving the reliability of the locking mechanism. At the same time, the locking mechanism also forms a compact overall module, which is convenient for assembly and maintenance of the locking mechanism.

[0040] Among them, the unlocking mechanism includes a mechanical lock core 91, one end of the mechanical lock core 91 is not exposed from the box body 2, and the other end of the mechanical lock core 91 is directly or indirectly connected to the second connecting part 62 of the linkage 6, so that when the mechanical lock core 91 is rotated, the second connecting part 62 can be driven to generate an unlocking rotational force for the linkage 6 to rotate in the first direction.

[0041] In some other embodiments, the unlocking mechanism includes: a motor 92, an output end 921 of the motor 92 is connected to the second connecting portion 62 through a transmission rod 93; a control circuit board for driving the motor 92; an input device electrically connected to the control circuit to input an unlocking command. The input device includes a password button 95 and / or a fingerprint sensor 96, both of which are exposed on the box 1, so that after the user enters the correct preset password or fingerprint, the control circuit drives the motor 92 to operate and switch the locking structure to the unlocking state.

[0042] The motor 92 is fixed to the column 94 of the inner partition 13 through the fixing seat 932 , so that the motor 92 is fixedly installed on the inner partition 13 .

[0043] The output end 921 of the motor 92 is set as a flat shaft, and a flat shaft hole 931 is provided at the end of the transmission rod 93 away from the second connection part 62. The output end 921 is inserted into the flat shaft hole 931, so that when the output end 921 of the motor 92 rotates, the second connection part 62 of the linkage 6 is pulled by the transmission rod 93 to rotate around the second rotation axis 42 by a predetermined amplitude, and the end of the rotating linkage part 61 gradually slides from the locking side surface 531 into the unlocking side surface 532 to form a side contact with the locking side surface 531, so that the locking structure switches from the locked state to the unlocked state. Correspondingly, after the motor 92 is reset, the locking structure will also switch from the unlocked state to the locked state.

[0044] Of course, the housing 1 is also provided with a battery for powering the motor 92, the control circuit board and the fingerprint sensor 96. In addition, the housing 1 is also provided with a power supply port 97, so that when the battery power is insufficient, the motor 92, the control circuit board and the fingerprint sensor 96 can be powered by an external power supply through the power supply port 97.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
