[0044] Implementation Method 1

[0045] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, a lock structure is provided in an embodiment of the utility model, which includes a shell 100, a lock buckle 200, a fixing member 300, a driving mechanism 500 and a control mechanism 600. The shell 100 is provided with a lock opening for the lock nose 10 to enter and exit. The lock buckle 200 is rotatably arranged in the shell 100 and is placed on one side of the lock opening. The fixing member 300 is rotatably arranged in the shell 100. The fixing member 300 has: a first locked position connected to the lock buckle 200 and a first unlocked position released from the lock buckle 200. The driving mechanism 500 can be used to drive the fixing member 300 to switch from the first locked position to the first unlocked position and / or from the first unlocked position to the first locked position.

[0046] The control mechanism 600 includes a control module and an in-place detection module. The control module is electrically connected to the in-place detection module and / or the driving mechanism 500. The in-place detection module is arranged on one side of the fixing member 300 and / or the driving mechanism 500. The in-place detection module can be used to obtain the position signal of the lock 200, the fixing member 300 and / or the driving mechanism 500. The control module can control the movement state of the driving mechanism 500 based on the position signal feedback.

[0047] On the whole, when the lock structure is used, the lock structure and the lock nose 10 are respectively arranged on the cabinet body and the cabinet door, and the lock structure can be used to lock or unlock with the lock nose 10, thereby helping to improve the anti-theft performance of the cabinet door.

[0048] Specifically, a lock catch 200 and a fixing member 300 are provided in the housing 100, and the fixing member 300 has a first locking position in which the lock catch 200 is limited and connected, and a first unlocking position in which the lock catch 200 is released from the limit. That is, when the lock nose 10 is inserted into the housing 100 from the lock port, the lock nose 10 can push the lock catch 200 to rotate to be limited and connected with the fixing member 300, so that the lock catch 200 and the fixing member 300 are locked, and the fixing member 300 is in the first locking position. When the fixing member 300 and the lock catch 200 are released from the limit, the lock catch 200 can rotate to separate from the lock nose 10, and the fixing member 300 is in the first unlocking position.

[0049] In order to better control the movement state of the driving mechanism 500, a control mechanism 600 is further provided in the shell 100. The position signals of the lock buckle 200, the fixing member 300 and / or the driving mechanism 500 can be obtained through the in-place detection module, so that the control module can control the movement state of the driving mechanism 500 based on the position signal, and then the driving mechanism 500 can be used to better drive the fixing member 300 to switch between the first locked position and the first unlocked position, thereby improving the movement stroke accuracy of the fixing member 300 and helping to maintain the position stability of the fixing member 300, so that the fixing member 300 can be used to better limit the lock buckle 200, avoiding the lock buckle 200 from accidentally disengaging from the fixing member 300 under the action of external force, significantly improving the seismic resistance of the lock structure, and helping to maintain the unlocking success rate of the lock structure.

[0050] Furthermore, the driving mechanism 500 can also drive the fixing member 300 to switch from the first locking position to the first unlocking position, thereby playing a role in assisting unlocking and having a better unlocking efficiency.

[0051] In the implementation mode of the present utility model, Figure 1 , Figure 4 and Figure 5 In the embodiment shown, the lock structure includes a linkage mechanism 400, which includes a linkage member 410, which is slidably disposed in the housing 100, and a mounting hole 420 is provided at one end of the linkage member 410, through which the linkage member 410 is adjustably connected to the fixing member 300, and an adjustment slot 430 is provided at the other end of the linkage member 410, through which the linkage member 410 is driveably connected to the driving mechanism 500. Preferably, the linkage mechanism 400 is movably disposed in the housing 100.

[0052] The lock structure is also provided with a linkage mechanism 400, and the driving mechanism 500 can control the position of the fixing member 300 through the linkage mechanism 400, that is, the fixing member 300 can be switched from the first locking position to the first unlocking position through the driving mechanism 500 to release the lock buckle 200. Alternatively, the position of the fixing member 300 can be maintained through the locking action of the driving mechanism 500, so that the lock buckle 200 can be more stably limited by the fixing member 300, avoiding the problem of accidental separation of the lock buckle 200 and the fixing member 300, which helps to increase the anti-seismic performance and anti-theft performance of the lock structure.

[0053] In a specific embodiment, the linkage member 410 includes a latch piece, which is slidably inserted into the housing 100. Designers can adjust the specific structure of the latch piece according to usage requirements, such as setting the latch piece to a long strip shape, which is not specifically limited here.

[0054] And, if Figure 5In the embodiment shown, the adjustment groove 430 includes a first slide groove section 431 extending along the movement direction of the linkage 410, and a second slide groove section 432 arranged perpendicular to the movement direction of the linkage 410, and the second slide groove section 432 is arranged on one side of the first slide groove section 431 and connected to the middle part of the first slide groove section 431.

[0055] Designers can adjust the specific lengths of the first chute section 431 and the second chute section 432 according to usage requirements, and no specific limitation is made here.

[0056] By cooperating with the first slide groove section 431 and the second slide groove section 432 and the driving mechanism 500, the driving mechanism 500 can control the movement position of the linkage member 410, so that the linkage member 410 can be used to drive the fixing member 300 to switch between the first locked position and the first unlocked position, or the driving mechanism 500 can be used to lock the fixing member 300 to improve the shock resistance of the lock 200.

[0058] Specifically, Figure 1 and Figure 5 In the embodiment shown, the adjusting member includes a cam 520 disposed on the rotating shaft of the driving motor 510, and a protruding slider 530 is disposed on the cam 520. The slider 530 can be slidably inserted into the adjusting groove 430. The designer can adjust the specific structure of the slider 530 according to the use requirements, for example, setting the slider 530 to be cylindrical, which is not specifically limited here.

[0059] By arranging the cam 520 on the rotating shaft of the driving motor 510, when the driving motor 510 drives the cam 520 to rotate through the rotating shaft, the cam 520 can synchronously drive the slider 530 to rotate, and then the slider 530 cooperates with the adjusting slot 430 to realize different functions.

[0060] That is, when the slider 530 slides in the adjustment slot 430, the slider 530 can drive the linkage member 410, so that the fixing member 300 is switched from the first locked position to the first unlocked position by the linkage member 410. Alternatively, by utilizing the locking effect of the driving motor 510, the relative position of the slider 530 and the adjustment slot 430 remains unchanged, so as to maintain the position of the fixing member 300, and the fixing member 300 can be used to limit the lock buckle 200 more stably, and the problem of accidental unlocking of the lock buckle 200 and the fixing member 300 under the action of external force is avoided.

[0075] Designers can adjust the specific structure of the circuit board 610 or the specific structure of the external harness linking structure 640 according to usage requirements, and no specific limitation is made here.

[0076] In another feasible implementation of the present utility model, as Figure 2 and Figure 3In the embodiment shown, the lock structure includes a linkage mechanism 400, the linkage mechanism 400 includes a linkage member 410, one end of the linkage member 410 is provided with a mounting hole 420, the fixing member 300 includes a fixing buckle 310 and a connecting rod 320, one end of the connecting rod 320 is connected to the fixing buckle 310, and the other end of the connecting rod 320 is adjustably inserted into the mounting hole 420, the fixing buckle 310 is rotatably connected to the shell 100, and the fixing buckle 310 is provided with a limiting groove 330 and a boss 340, and the in-place detection module can be used to obtain the position signal of the boss and / or the fixing member.

[0077] Specifically, the in-place detection module includes at least a first in-place switch 620.

[0078] By setting the mounting hole 420 at one end of the linkage member 410, when the connecting rod 320 is plugged into the mounting hole 420, there is a certain adjustment margin between the connecting rod 320 and the linkage member 410, thereby avoiding the problem of the connecting rod 320 and the linkage member 410 being stuck.

[0079] The designer can adjust the specific structure of the boss 340 according to the use requirements, and no specific limitation is made here. Preferably, at least part of the body of the fixing buckle 310 forms the boss 340, so that the boss 340 and the fixing buckle 310 are integrally arranged, which has better structural strength.

[0080] In the implementation mode of the present utility model, Figure 2 , Figure 3 and Figure 4 In the embodiment shown, the inner wall of the limiting groove 330 is formed with a first limiting end face 331 and a second limiting end face 332. Along the rotation direction of the lock buckle 200, the first limiting end face 331 and the second limiting end face 332 are arranged at intervals. When the lock buckle 200 is clamped in the limiting groove 330, the first limiting end face 331 and the second limiting end face 332 can play a circumferential limiting role on the lock buckle 200.

[0083] When the lock buckle 200 is inserted into the limiting groove 330, the lock buckle 200 can be limited by the first limiting end surface 331 and the second limiting end surface 332, so as to prevent the lock buckle 200 from being excessively pushed inward by the user or being disengaged from the limiting groove 330. Even when the lock buckle 200 encounters violent knocking, vibration testing, external prying, violent door slamming, etc., the lock buckle 200 can still remain in the target position, and has better anti-vibration performance.

Preferably, the housing 100 can be configured as one of a die casting, a metal stamping, and a plastic injection molding.

[0091] Further, such as Figure 2 In the embodiment shown, a first limiting column 110 and a second limiting column 120 are also provided on the shell 100. The first limiting column 110 is arranged on the rotation path of the fixing buckle 310 to limit the movement range of the fixing buckle 310, and the second limiting column is arranged on the rotation path of the locking buckle 200 to limit the movement range of the locking buckle 200.

[0092] Designers can adjust the specific structures of the first limiting column 110 and the second limiting column according to usage requirements, and no specific restrictions are made here.

[0093] In the embodiment of the utility model, the designer can adjust the specific structure and material of the lock buckle 200 according to the use requirements, and no specific restrictions are made here. Preferably, the lock buckle 200 can be configured as one of a die casting, powder metallurgy, and metal pressing. In addition, a lock groove for limiting the lock nose 10 is provided on the lock buckle 200, and the lock groove can be configured as a U-shaped groove.

[0094] In order to prevent the lock nose 10 from slipping out of the lock buckle 200, in the embodiment of the present utility model, Figure 7 In the embodiment shown, a folding structure 130 can be provided at the lock opening, and the folding structure 130 can play a certain limiting role on the lock nose 10, so that when the lock nose 10 is pulled by external force, the folding structure 130 can prevent the lock nose 10 from being pried and sliding out of the lock buckle 200.

[0095] Specifically, the folding structure 130 includes a folding piece, and the folding piece can be covered on a side housing 100 of the lock. Designers can adjust the specific structure of the folding structure 130 according to usage requirements, and no specific limitation is made here.

[0096] In an embodiment of the present invention, an elastic structure is also included, which is used to drive the fixing member 300 to switch from the first unlocking position to the first locking position, and / or to drive the lock buckle 200 to switch from the second locking position to the second unlocking position, and / or to push the cabinet door.

[0097] In a feasible implementation of the present utility model, if Figure 1 and Figure 2 In the illustrated embodiment, the elastic structure includes a first elastic structure, which is disposed between the fixing member 300 and the housing 100 , and can be used to drive the fixing member 300 to switch from a first unlocking position to a first locking position.

[0098] In a specific embodiment, the first elastic structure includes a fixing buckle torsion spring 360. In addition, in order to improve the installation stability and installation accuracy of the fixing buckle torsion spring 360, a fixing buckle positioning column 370 may be provided in the housing 100. The fixing buckle torsion spring 360 is first connected to the connecting rod 320 on the fixing buckle 310, and then pressed into the fixing buckle positioning column 370 in the housing 100. At this time, the fixing buckle torsion spring 360 is in a compressed state.

[0099] Of course, in other feasible embodiments, designers can adjust the specific structure of the first elastic structure according to usage requirements, and no specific limitation is made here.

[0100] In another feasible implementation of the present utility model, as Figure 1 and Figure 2 In the embodiment shown, the elastic structure includes a second elastic structure, which is arranged between the lock buckle 200 and the shell 100. The lock buckle 200 has a second locked position and a second unlocked position. When the lock buckle 200 is in the second locked position, the lock buckle 200 can be used to connect the lock nose 10, and the second elastic structure can be used to drive the lock buckle 200 to switch from the second locked position to the second unlocked position.

[0101] In a specific embodiment, the second elastic structure includes a lock torsion spring 210. In addition, in order to improve the connection reliability between the lock 200 and the lock torsion spring 210, a positioning groove may be provided on the lock 200 to position the lock torsion spring 210.

[0102] During installation, the lock 200 and the lock torsion spring 210 are assembled, and in order to improve the installation stability and installation accuracy of the lock torsion spring 210, a lock positioning column 220 can be set in the shell 100, and the lock 200 is pressed into the lock positioning column 220 in the shell 100. At this time, the lock torsion spring 210 is in an uncompressed state.

[0103] Of course, in other feasible embodiments, designers can adjust the specific structure of the second elastic structure according to usage requirements, and no specific limitation is made here.

[0104] In another feasible implementation manner of the present utility model, as Figure 1 and Figure 2In the embodiment shown, the elastic structure includes a third elastic structure. The lock structure also includes a top rod 700, which is movably arranged on the shell 100. The top rod 700 has: an extended position for pushing the cabinet door and a storage position compressed by the cabinet door. A third elastic structure is provided between the top rod 700 and the shell 100, and the third elastic structure can be used to drive the top rod 700 to switch from the storage position to the extended position.

[0105] The push rod 700 cooperates with the third elastic structure, so that when the cabinet door is closed, the cabinet door can compress the push rod 700 and the third elastic structure, so that the push rod 700 is stored in the shell 100.

[0106] When the fixing member 300 and the lock catch 200 are unlocked, the third elastic structure can drive the push rod 700 to push the cabinet door to open, thereby achieving better door opening efficiency.

[0107] In one possible embodiment, if Figure 1 and Figure 2 In the illustrated embodiment, the third elastic structure includes a push rod compression spring 710 sleeved on the push rod 700, the push rod compression spring 710 connects the push rod 700 and the housing 100, and the push rod compression spring 710 can store elastic potential energy to push the push rod 700 to move.

[0108] After the fixing buckle torsion spring 360 and the locking buckle torsion spring 210 are installed, the push rod 700 and the push rod compression spring 710 are assembled to the target position in the housing 100. The designer can adjust the specific structure of the third elastic structure according to the use requirements, and no specific limitation is made here.

[0109] In the implementation of the utility model, the locking principle of the lock structure is:

[0110] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 In the embodiment shown, the lock structure and the lock nose 10 are installed between the cabinet door and the cabinet body respectively. Generally, the lock nose 10 is installed on the movable end cabinet door, and the lock structure is installed on the fixed end cabinet body. After the lock structure is installed, the lock structure can be set to an unlocked state, at which time the first in-position switch 620 is pressed by the boss 340 on the fixing buckle 310, and the second in-position switch 630 is in a disconnected state with the cam 520, and the server can be reported to show that the state is unlocked.

[0111] In the unlocked state, Figure 2In the embodiment shown, the direction of the force of the fixing buckle torsion spring 360 is the first direction F1, and the direction of the force of the lock buckle torsion spring 210 is the second direction F2. The fixing buckle 310 moves in the first direction F1 under the force of the fixing buckle torsion spring 360, the guide portion 350 on the fixing buckle 310 abuts against the lock buckle 200, and the lock buckle 200 can be limited by the shell 100 when moving along the second direction F2.

[0112] When the user closes the cabinet door, Figure 3 In the embodiment shown, the lock nose 10 pushes the lock buckle 200 to move into the shell 100, and the lock buckle 200 can abut against the guide portion 350 and move along the guide portion 350. At this time, the force of the fixed buckle torsion spring 360 and the force of the lock buckle torsion spring 210 remain unchanged, but the force of the lock buckle torsion spring 210 increases as the lock buckle 200 moves into the shell 100.

[0113] When the lock buckle 200 moves along the guide portion 350 to the limiting groove 330, the force of the fixing buckle torsion spring 360 presses the limiting groove 330 onto the lock buckle 200 to play a limiting role. At this time, the shell 100 can also be used to limit the fixing buckle 310, so that the fixing buckle 310 cannot continue to rotate under the force of the fixing buckle torsion spring 360.

[0114] At the same time, the fixing buckle 310 can drive the linkage member 410 to move during the rotation process. When the fixing buckle 310 is disconnected from the first in-position switch 620, the driving motor 510 drives the cam 520 to move. When the cam 520 moves to the second in-position switch 630, the driving motor 510 stops. Figure 5 In the embodiment shown, the slider 530 on the cam 520 is located in the second slide groove section 432, forming a right angle of 90° with the linkage member 410, so as to limit the linkage member 410, and the linkage member 410 cannot move to pull the fixing buckle 310 to perform an action. In this state, the signal state reported to the server is locked. At this time, the lock nose 10 falls into the lock buckle 200, and the lock nose 10 cannot be pulled out.

[0115] At the same time, the cabinet door compresses the push rod 700 and the push rod compression spring 710 backwards, the push rod compression spring 710 is in a compressed state, and the force of the push rod 700 is on the cabinet door.

[0116] When the user continues to close the door forward or violently swings the door, that is, the lock nose 10 continues to move into or out of the housing 100, the first limiting end surface 331 and the second limiting end surface 332 of the fixing buckle 310 can be used to limit the movement of the lock buckle 200, thereby better protecting the in-position switch or other mechanisms from damage. At this time, the lock nose 10 is still in the U-shaped groove of the lock buckle 200 and cannot be disengaged.

[0117] In the implementation of the utility model, the unlocking principle of the lock structure is:

[0118] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 In the embodiment shown, when the unlocking command is issued, the driving motor 510 is powered on to drive the cam 520, and the slider 530 on the cam 520 drives the linkage member 410 to move. One end of the linkage member 410 is connected to the connecting rod 320 on the fixing buckle 310. At this time, the limiting groove 330 on the fixing buckle 310 is separated from the lock buckle 200, and the lock buckle 200 slides out along the guide part 350 of the fixing buckle 310 with the compression force of the lock buckle torsion spring 210, so that the lock buckle 200 is ejected. At the same time, the push rod compression spring 710 drives the push rod 700 to reset to push the door open.

[0119] At this time, the boss 340 on the fixing buckle 310 presses the first in-position switch 620. The cam 520 on the driving motor 510 is in the unlocked state, the cam 520 is disconnected from the second in-position switch 630, and the driving motor 510 stops working. At this time, the first in-position switch 620 is pressed and the second in-position switch 630 is disconnected.

[0120] Of course, in other feasible embodiments, designers can adjust the specific usage of the lock structure according to usage requirements, and no specific restrictions are made here.
