Figure 1 and Figure 2 and Figure 8The present embodiment provides a lock 010, which includes a lock buckle 100 and a lock body assembly 200 for cooperating with or separating from the lock buckle 100, wherein the lock body assembly 200 includes a base frame 210, a lock hook 220, a locking member 230 and a driving assembly 240, the lock hook 220 is rotatably arranged on the base frame 210, the lock hook 220 is configured to be engaged with or separated from the lock buckle 100, the locking member 230 is movably connected to the lock hook 220, the locking member 230 has a first position cooperating with the lock hook 220 and a second position separating from the lock hook 220, when the lock member 230 is engaged with the lock hook 220, the lock hook 220 is engaged with the lock hook 220, and the lock member 230 is engaged with the lock hook 220. 0 is in the first position, the lock hook 220 is separated from the lock buckle 100, and when the locking member 230 is in the second position, the lock hook 220 is engaged with the lock buckle 100; the above-mentioned driving assembly 240 is in transmission connection with the locking member 230, and when the driving assembly 240 drives the locking member 230 to be in the first position, the locking member 230 drives the lock hook 220 to be separated from the lock buckle 100; when the lock buckle 100 is engaged with the lock hook 220, the lock hook 220 drives the locking member 230 to move from the first position to the second position, and the driving assembly 240 locks the locking member 230 in the second position. In detail, the lock hook 220 has a third position in which it is engaged with the lock buckle 100 and a fourth position separated from the lock buckle 100, when the lock hook 220 is in the third position, the locking member 230 is in the second position, and when the lock hook 220 is in the fourth position, the locking member 230 is in the first position. By providing a locking member 230 movably connected to the lock hook 220, when the lock hook 220 is located in the third position and engages with the lock buckle 100 to achieve locking, if an external force acts on the lock hook 220 or the lock buckle 100, since the locking member 230 is located in the second position and separated from the lock hook 220 located in the third position, the external force will not be transmitted to the locking member 230 through the lock hook 220, and will not be transmitted to the drive assembly 240 through the locking member 230, that is, the external force will not be directly transmitted to the drive assembly 240 through the lock hook 220, but will be buffered by the locking member 230, thereby reducing the impact of the external force on the drive assembly 240, extending the service life of the drive assembly 240, and improving the reliability of the locking and unlocking functions of the lock 010.

[0038] Figure 3 for Figure 1 A magnified view of the local structure at point III; Figure 4 for Figure 2 The enlarged view of the local structure at position IV in the middle; please refer to Figure 3 and Figure 4In the present embodiment, the locking member 230 has a first surface 231, and the lock hook 220 has a second surface 221. When the locking member 230 is in the first position, the first surface 231 and the second surface 221 are abutted and matched. When the locking member 230 is in the second position, the first surface 231 and the second surface 221 are separated. In detail, when the lock hook 220 is switched to the third position, the lock hook 220 and the lock buckle 100 are engaged and matched. At this time, the locking member 230 is in the second position, and the first surface 231 of the locking member 230 is separated from the second surface 221 of the lock hook 220, so that the locking member 230 is separated from the lock hook 220. If an external force acts on the lock hook 220 or the lock buckle 100, since the locking member 230 and the lock hook 220 are separated, the external force will not pass through the lock hook 220. The external force is transmitted to the locking member 230, so that it will not be transmitted to the driving component 240 which is transmission connected to the locking member 230 through the locking member 230, that is, the external force will not be directly transmitted to the driving component 240 through the locking hook 220, so as to avoid the external force from damaging the driving component 240, which can effectively extend the service life of the driving component 240 and improve the reliability of the lock 010; when the driving component 240 drives the locking member 230 to switch to the first position, the first surface 231 of the locking member 230 abuts and cooperates with the second surface 221 of the locking hook 220, so that when the locking member 230 moves to the first position, the locking member 230 can drive the locking hook 220 to switch to the fourth position, so that the locking hook 220 is separated from the lock buckle 100, thereby realizing the unlocking function of the lock 010.

[0039] Figure 5 This is a partial structural exploded view of the lock assembly 200 in an embodiment of the present invention; please refer to Figure 1 , Figure 2 and Figure 5 The lock body assembly 200 of this embodiment also includes a first rotating shaft 261, which is arranged on the base frame 210. The above-mentioned lock hook 220 and the locking member 230 are pivotally connected to the first rotating shaft 261 at the same time. In this way, when the lock hook 220 is engaged with the lock buckle 100, the lock hook 220 can be used to more stably drive the locking member 230 to move from the first position to the second position, and the driving assembly 240 can be used to lock the locking member 230 in the second position to ensure that the locking member 230 is separated from the lock hook 220.

[0040] Please refer to Figure 1 , Figure 3 and Figure 4The locking member 230 of this embodiment also includes a third surface 232, and the lock 010 also includes a locking member 250. The locking member 250 is rotatably arranged on the base frame 210, and the locking member 250 has a fourth surface 251, and the locking member 250 is provided with a slide groove 252; the lock hook 220 is provided with a plug column 222, and the plug column 222 can be slidably inserted in the slide groove 252, and the slide groove 252 cooperates with the plug column 222, so that the lock hook 220 can only rotate between the third position and the fourth position, and when the locking member 230 is located in the second position, the third surface 232 and the fourth surface 251 abut and cooperate, and the locking member 230 prevents the locking member 250 from rotating, thereby preventing the lock hook 220 from rotating, and locking the lock hook 220 When the locking member 230 is in the first position, the third surface 232 is separated from the fourth surface 251, thereby releasing the locking member 230 from locking the position of the locking member 250, that is, releasing the locking member 250 from locking the position of the locking hook 220, and the locking hook 220 can rotate within the set angle range; in detail, when the locking member 230 is in the second position, and the locking hook 220 is in the third position and is engaged with the lock buckle 100, the third surface 232 is in contact with the fourth surface 251, which can prevent the lock buckle 100 or the locking hook 220 from rotating when subjected to vibration or external force, thereby preventing the locking hook 220 from separating from the lock buckle 100, thereby further improving the stability of the locking effect of the lock 010.

[0041] Please refer to Figure 1 , Figure 2 and Figure 5The lock 010 of this embodiment further includes a third rotating shaft 263, which is fixedly arranged on the base frame 210, and the locking member 250 is rotatably sleeved on the third rotating shaft 263, wherein the third rotating shaft 263 and the first rotating shaft 261 are arranged in parallel with each other at intervals; further, the slide groove 252 of this embodiment is arranged in an oval shape, and when the third surface 232 and the fourth surface 251 are abutted and matched, the slide groove 252 is located between the third rotating shaft 263 and the first rotating shaft 261, and the end of the slide groove 252 close to the third rotating shaft 263 is the first end, and the end of the slide groove 252 away from the third rotating shaft 263 is the second end. When the locking member 250 rotates around the third rotating shaft 263 When the locking member 230 is in the second position, the plug 222 inserted in the slide slot 252 can slide between the first end and the second end of the slide slot 252; when the locking member 230 is in the second position, the plug 222 is located at the first end of the slide slot 252. When the locking member 230 switches from the second position to the first position, the fourth surface 251 of the locking member 250 is separated from the third surface 232 of the locking member 230. At this time, the locking member 230 drives the lock hook 220 to rotate, and the plug 222 on the lock hook 220 slides from the first end to the second end of the slide slot 252. When the lock hook 220 switches from the third position to the fourth position as the locking member 230 rotates, the plug 222 is located at the second end of the slide slot 252. In the above process, the gravity of the locking member 250 makes the slide slot 252 have a tendency to rotate around the rotation axis to drive the lock hook 220 to rotate to the fourth position, so that the lock hook 220 can be more smoothly rotated to the fourth position separated from the lock buckle 100.

[0042] Preferably, please refer to Figure 2 When the third surface 232 of the locking member 230 is in abutment with the fourth surface 251 of the locking member 250, the distance between the abutment position of the third surface 232 and the fourth surface 251 and the first rotating shaft 261 is smaller than the distance between the clamping position of the lock hook 220 and the lock buckle 100 and the first rotating shaft 261. In this way, when the lock hook 220 is in a clamping position with the lock buckle 100, the torque of the lock buckle 100 acting on the lock hook 220 is reduced, which can reduce the load when the driving component 240 drives the locking member 230 to unlock.

[0043] Fig. 9 FIG. 2 is a schematic diagram of the structure of the locking member 230 in an embodiment of the present invention. Fig. 9 In this embodiment, a protrusion is provided on the side of the locking member 230 away from the base frame 210, and the first surface 231 and the third surface 232 are two adjacent surfaces of the protrusion.

[0044] Please refer to Figure 1 , Figure 2 and Figure 5The driving assembly 240 of this embodiment includes a transmission member 241, a second rotating shaft 262, and a first elastic member 247. The second rotating shaft 262 is fixedly arranged on the base frame 210. The transmission member 241 is rotatably sleeved on the outside of the second rotating shaft 262. The transmission member 241 has a first section 242 located on one side of the second rotating shaft 262. The first end of the first elastic member 247 is connected to the base frame 210, and the second end of the first elastic member 247 is connected to the locking member 230. The first elastic member 247 is configured to make the locking member 230 always have a direction When the locking member 230 is in the second position, the end of the first section 242 abuts against the locking member 230, and the locking member 230 is locked in the second position under the joint action of the first elastic element 247 and the first section 242, which is conducive to the lock hook 220 being more stably located in the third position; when the end of the first section 242 is separated from the locking member 230, the first elastic element 247 drives the locking member 230 to switch to the first position, so that the lock hook 220 can switch to the fourth position, and release the lock hook 220 from locking the lock buckle 100. The first elastic element 247 of this embodiment is a tension spring, and optionally, in other embodiments, the first elastic element 247 is an elastic rubber strip, a torsion spring, etc.

[0045] For further information, please refer to Figure 1 and Figure 2 In this embodiment, the locking member 230 is provided with a first arc surface 313, and the first section 242 is provided with a second arc surface 314. When the locking member 230 rotates from the first position to the second position, the first arc surface 313 slides relative to the second arc surface 314. In this way, the locking member 230 can move more smoothly from the first position to the second position, which is beneficial for the end of the first section 242 to abut against the locking member 230, so as to lock the locking member 230 in the second position.

[0046] Please refer to Figure 1 and Figure 2The transmission member 241 further includes a second section 243, which is located at the other side of the second rotating shaft 262. The driving assembly 240 of this embodiment further includes a driving member, which is in transmission connection with the second section 243. The driving member is configured to drive the second section 243 to rotate so that the end of the first section 242 abuts against or separates from the locking member 230. When the lock hook 220 needs to be switched from the third position to the fourth position, the driving force of the driving member needs to overcome the abutment force between the first section 242 of the transmission member 241 and the locking member 230 to achieve unlocking. In this embodiment, when the lock hook 220 is located at the third position, If there is an external force that causes the lock buckle 100 and the lock hook 220 to tend to separate, for example, the volume of the items in the locker 020 is too large and squeezes the cabinet door 310 outward, exerting a force on the lock buckle 100 in the direction of separating from the lock hook 220, the load of the drive member to unlock will increase. Since the locking member 230 is in the second position separated from the lock hook 220, the external force will not be directly transmitted to the second section 243 of the transmission member 241, but will be transmitted to the drive member through the locking member 250, the locking member 230, and the transmission member 241. Through the leverage effect, the load of the drive member is reduced and the unlocking ability of the drive member is improved.

[0047] Figure 6 FIG. 2 is a partial structural diagram of the locking hook 220 and the lock buckle 100 in the embodiment of the present invention. Figure 6 , the driving force of the driving member acting on the first section 242 is set to F1, the external force is set to F2, the distance between the first section 242 and the first rotating shaft 261 is set to the first distance S1, the distance between the engaging position of the lock hook 220 and the lock buckle 100 and the first rotating shaft 261 is set to the second distance S2, the distance between the abutting position of the third surface 232 and the fourth surface 251 and the first rotating shaft 261 is set to the third distance S3, the distance between the abutting position of the third surface 232 and the fourth surface 251 and the third rotating shaft 263 is set to the fourth distance S4, the distance between the third rotating shaft 263 and the plug 222 is set to the fifth distance S5, and the distance between the plug 222 and the first rotating shaft 261 is set to the sixth distance S6. The ratio of the lever arm of the driving force F1 to the lever arm of the external force F2 is S1 / S2. In this embodiment, the ratio of the force arm of the driving force F1 to the force arm of the external force F2 is S1 / S3*S4 / S5*S6 / S2. In this embodiment, since the third distance S3 is smaller than the fourth distance S4, the ratio of the force arm of the driving force F1 to the force arm of the external force F2 is increased, that is, the load when the driving member is unlocked is reduced, thereby increasing the unlocking ability of the driving member. Further, in this embodiment, the sixth distance S6 is larger than the fifth distance S5, increasing the ratio of the force arm of the driving force F1 to the force arm of the external resistance F2, thereby further increasing the unlocking ability of the driving member.

[0048] Figure 7FIG. 2 is a structural diagram of the lock 010 from a first perspective when the lock hook 220 is located at the third position and the locking member 230 is located at the second position in an embodiment of the present invention; please refer to FIG. Figure 7 In detail, the driving member of the present embodiment is an electromagnet 244, and the armature 245 of the electromagnet 244 is transmission-connected with the second section 243 of the transmission member 241, and the armature 245 is configured to drive the second section 243 to rotate so that the first section 242 abuts against or separates from the locking member 230; further, when the lock hook 220 is engaged with the lock buckle 100, the lock hook 220 drives the locking member 230 to move from the first position to the second position and pass through the second position, and the armature 245 of the electromagnet 244 extends out, driving the second section 243 of the transmission member 241 to rotate around the second rotating shaft 262 in the first direction a, thereby driving the first section 242 to rotate around the second rotating shaft 262 in the first direction a, so that the end of the first section 242 is located on the rotation path of the locking member 230, and the locking member 230 is simultaneously driven by the second rotating shaft 262. An elastic element 247 is used to rotate toward the first position until the end of the first section 242 of the transmission member 241 abuts against the locking member 230 to lock the locking member 230 in the second position. When the armature 245 of the electromagnet 244 retracts, the second section 243 of the transmission member 241 is driven to rotate around the second rotating shaft 262 along the second direction b, thereby driving the first section 242 to rotate around the second rotating shaft 262 along the second direction b until the end of the first section 242 of the transmission member 241 is separated from the locking member 230. After the first section 242 is separated from the locking member 230, the locking member 230 can be switched to the first position under the elastic action of the first elastic element 247, so that the lock hook 220 can be switched to the fourth position, so that the lock hook 220 is separated from the lock buckle 100 to achieve unlocking. Optionally, in other embodiments, the driving member may also be a motor, which is transmission-connected to the second section 243 , and the motor is configured to drive the second section 243 to rotate so that the end of the first section 242 abuts against or separates from the locking member 230 .

[0049] It should be noted that, in this embodiment, the first rotating shaft 261 , the second rotating shaft 262 , and the third rotating shaft 263 are arranged in parallel and spaced apart.

[0050] Please refer to Figure 1 , Figure 2 and Figure 5The driving assembly 240 of this embodiment also includes an emergency rod 246, a first end of the emergency rod 246 is connected to the transmission member 241, and the second end of the emergency rod 246 extends out of the base frame 210. In detail, the first end of the emergency rod 246 is connected to an end of the second section 243 of the transmission member 241 away from the second rotating shaft 262, and the second end of the emergency rod 246 extends out of the base frame 210 in a direction away from the second section 243; when the electromagnet 244 works abnormally, an external force can be applied to the emergency rod 246 to make the emergency rod 246 and the transmission member 241 rotate together in the second direction b around the second rotating shaft 262, so that the first section 242 of the transmission member 241 is separated from the locking member 230, thereby realizing manual unlocking.

[0051] The lock 010 of this embodiment also includes a second elastic element 248 and a push rod 249. The push rod 249 is movably connected to the base frame 210. The first end of the second elastic element 248 is connected to the base frame 210, and the second end of the second elastic element 248 is connected to the push rod 249. The second elastic element 248 is configured to make the push rod 249 always have a movement tendency to drive the lock buckle 100 away from the lock hook 220. In this way, when the lock hook 220 is engaged with the lock buckle 100, the push rod 249 overcomes the action of the second elastic element 248 and retracts into the base frame 210. When the driving assembly 240 drives the lock hook 220 to separate from the lock buckle 100 through the locking member 230, the push rod 249 drives the lock buckle 100 to quickly move away from the lock hook 220 under the action of the second elastic element 248 to achieve more stable unlocking. In detail, a mounting plate 264 is provided on the base frame 210 of the present embodiment, and the push rod 249 can be slidably inserted into the mounting hole of the mounting plate 264. The outer wall fixing sleeve of the push rod 249 is provided with a fixing ring 265. The first end of the second elastic element 248 of the present embodiment abuts against the mounting plate 264, and the second end of the elastic element abuts against the fixing ring 265; further, the second elastic element 248 of the present embodiment is a compression spring. Optionally, in other embodiments, the second elastic element 248 can also be a tension spring, a torsion spring, an elastic rubber sleeve, etc.

[0052] Furthermore, the lock 010 of the present embodiment also includes a sensor 312, which is arranged on the base frame 210, and the sensor 312 is detachably matched with the lock hook 220 to detect whether the lock hook 220 and the lock buckle 100 are in a locked state or in a separated state; in detail, in the present embodiment, when the lock hook 220 is separated from the lock buckle 100, the sensor 312 cooperates with the lock hook 220, and the sensor 312 outputs a first detection signal; when the lock buckle 100 and the lock hook 220 are engaged, the lock hook 220 is separated from the sensor 312, triggering the sensor 312 to output a second detection signal; according to the detection signal output by the sensor 312, the armature 245 of the electromagnet 244 is controlled to extend and push the transmission member 241 to rotate along the first direction a; when the first elastic element 247 drives the locking member 230 to rotate toward the first position, the locking member 230 drives the lock hook 220 to rotate along the second direction b, so that the lock hook 220 is separated from the lock buckle 100, and the sensor 312 outputs the first detection signal.

[0053] Figure 8 This is a schematic diagram of the structure of the lock 010 in an embodiment of the present invention; please refer to Figure 8 The base frame 210 of this embodiment includes a cover plate 211 and a bottom plate 213, and the cover plate 211 and the bottom plate 213 are buckled to form a receiving space, and the aforementioned lock hook 220, locking member 230, locking member 250 and driving assembly 240 are all located in the aforementioned receiving space to protect the locking member 230, the lock hook 220, the locking member 250 and the driving assembly 240. It should be noted that a long hole 212 is opened on the side wall of the base frame 210 away from the lock hook 220, and the emergency rod 246 can extend from the long hole 212 and swing in the long hole 212.

[0054] Fig.10 This is a schematic diagram of the structure of the locker 020 in an embodiment of the present invention; please refer to Fig.10 The present embodiment further provides a storage cabinet 020, which includes a cabinet body 300, a cabinet door 310 and the above-mentioned lock 010. The cabinet body 300 has a storage compartment 311, and the cabinet door 310 is rotatably connected to the cabinet body 300. The cabinet door 310 has a closed position for closing the storage compartment 311 and an open position for opening the storage compartment 311. The lock buckle 100 of the lock 010 is arranged on the cabinet door 310, and the lock body assembly 200 is arranged on the cabinet body 300. When the cabinet door 310 is in the closed position and the lock hook 220 is in the third position, the lock buckle 100 is engaged with the lock hook 220 to lock the cabinet door 310 in the closed position. When the lock hook 220 is in the fourth position, the lock hook 220 is separated from the lock buckle 100 to release the lock of the cabinet door 310 in the closed position, so that the cabinet door 310 can be rotated to the open position to open the storage compartment 311. In detail, the lock body assembly 200 of the lock 010 is disposed on the inner wall of the storage compartment 311 so as to hide the lock body assembly 200 inside the storage compartment 311 .

[0055] When the lock 010 provided in this embodiment uses the lock hook 220 located in the third position to engage with the lock buckle 100, the lock hook 220 is separated from the locking member 230 located in the second position. If an external force acts on the lock buckle 100 or the lock hook 220, the external force will not be directly transmitted to the drive assembly 240 through the lock hook 220, but will be buffered by the locking member 230, thereby preventing the drive assembly 240 from being damaged by the external force, thereby extending the service life of the drive assembly 240 and improving the reliability of the lock 010. Therefore, when the storage cabinet 020 equipped with the lock 010 stores items, the cabinet door 310 can be more stably locked in the closed position to close the storage compartment 311, thereby improving the safety of the storage of items and more reliably unlocking the cabinet door 310, so that the cabinet door 310 can be smoothly switched from the closed position to the open position, thereby conveniently and reliably realizing the storage and retrieval of items.

[0056] In summary, the lock and locker of the present invention have the following beneficial effects:

[0057] When the lock provided by the embodiment of the present invention is in use, the driving component can drive the locking member to be in the first position through the driving component, so that the locking member drives the lock hook to separate from the lock buckle, or when the lock buckle is engaged with the lock hook, the driving component is used to lock the locking member in the second position to separate the locking member from the lock hook. Therefore, when the lock buckle is engaged with the lock hook, if the lock hook or the lock buckle is subjected to external force, the external force will not be directly transmitted to the driving component through the lock hook, but will be buffered by the locking member, thereby reducing the impact of the external force on the driving component, extending the service life of the driving component, and improving the reliability of the lock.

[0058] When the storage cabinet provided by the embodiment of the present invention is in use, when the cabinet door is rotated to the closed position, the lock hook can be engaged with the lock buckle arranged on the cabinet door, and the lock hook is used to drive the locking member to move from the first position to the second position, and the driving component can lock the locking member in the second position to separate the locking member from the lock hook. At this time, if the lock hook or the lock buckle is subjected to external force, the external force will not be directly transmitted to the driving component through the lock hook, but will be further buffered by the locking member, thereby reducing the impact of the external force on the driving component, extending the service life of the driving component, and improving the reliability of the lock in locking or unlocking the cabinet door.
