Referring to fig. 8, optionally, the rear cover plate 1312 has a mounting chute 13121, and the rear cover plate 1312 may be hung on a screw of the mounting plate 200 through the mounting chute 13121 to fix the locking box 100.

When the locking box 100 is unlocked, the computer key is inserted into the wireless key interface 13111, and the locking component 132 can be unlocked after the control component 134 obtains power and identifies the identity information. At this time, the locking assembly 132 moves out of the locking hole 1211 of the latch bolt 121, and the ejector assembly 133 ejects the locking cover 120 away from the fixing base 110, so that the locking cover 120 is in the open position, thereby unlocking the lock box 100. When the lock box 100 is locked, the lock cover 120 is pressed in a direction toward the fixing base 110, the lock cover 120 drives the eject member 133 to move in a direction toward the fixing base 110, and at the same time, the lock member 132 may extend into the lock hole 1211 of the latch tongue 121, thereby locking the lock box 100.

The present invention provides a lock box 100 that provides power and communication to the control assembly 134 of the lock body structure 130 via wireless communication techniques. When the computer key is matched with the identity information of the control component 134, the locking box 100 can be unlocked without manually operating the computer key, and the locking box 100 can be locked without using the computer key by directly pressing the locking cover 120. The problem of inconvenient operation that the present locking box can only carry out unblock and shutting operation to rotate the computer key leads to is effectively solved, like this, locking box 100 when locking and unblock, need not operate the computer key can non-contact open or close locking box 100, easy operation, convenient to use of user.

Alternatively, the lock box 100 may replace the holder 110 and the lock cover 120 of different sizes so that the holder 110 and the lock switch 400 can accommodate the lock switch 400 of different sizes. As shown in fig. 1 and 2, fig. 1 shows the lock box 100 with a smaller sized lock cover 120, and fig. 2 shows the lock box 100 with a larger sized lock cover 120.

Referring to fig. 10, in one embodiment, the holder 110 is provided with a position-limiting guide rail 112, and the lock body structure 130 is provided with a position-limiting guide groove 13112 matched with the position-limiting guide rail 112 for mounting the lock body structure 130 to the holder 110. Specifically, the retaining guide 13112 is located on the lock body housing 1311. When the fixing base 110 is installed, the limit guide rail 112 of the fixing base 110 is inserted into the corresponding limit guide slot 13112 of the lock body structure 130, and then the rear cover plate 1312 is fixed and locked to the lock body structure 130 by screws, thereby completing the assembly of the locking box 100. Also, the holder 110 may be flexibly designed and assembled to the lock case 100 according to the size and installation space of the lock switch.

Referring to fig. 3 and 4, in one embodiment, the control assembly 134 includes a control board 1341 and an induction coil 1342; the induction coil 1342 is disposed in the locking housing 1321 and is close to the wireless key interface 13111, the control board 1341 has an identity tag storage module, a wireless power supply module and a communication module, the computer key supplies power to the wireless power supply module through the induction coil 1342, and the computer key is matched with the identity tag storage module in identity through the communication module.

It can be understood that the wireless power supply module can utilize the electric energy obtained from the induction coil to supply power to the control assembly, and can also have an energy storage function and be responsible for supplying power to the control assembly.

The induction coil 1342 is close to the wireless key interface 13111, so that power can be conveniently supplied to a computer key. The computer key may provide power to the wireless power module through the induction coil 1342. Then, the computer key and the identity label storage module are in communication connection through the communication module so as to identify the identity information of the computer key. The identity tag storage module stores identity information of a computer key adapted to the lock box 100. Thus, when the identity information of the computer key matches the identity information of the control component 134, the lock box 100 can be unlocked. When the identity information of the computer key does not match the identity information of the control component 134, the lock box 100 cannot be unlocked.

Illustratively, the induction coil 1342 is a wireless power coil. Optionally, the computer key has a wireless power supply module, a communication module and an identity identification module.

It will be appreciated that the extension of the locking pin 1322 into the latching aperture 1211 is effected by the resilient force of the locking pin spring 1323 and the movement of the locking pin 1322 out of the latching aperture 1211 is effected by an external force. The detent spring 1323 in the latch assembly 132 is in a compressed state. Thus, the latch 1322 is extended into the latching hole 1211 of the latch tongue 121 by the elastic force of the latch spring 1323, and the latching cover 120 is locked. In the electrically unlocked state, the latch 1322 is retracted by the pressure of the latch bolt 121 to compress the latch spring 1323, and at this time, the latch 1322 may move out of the latching hole 1211 of the latch bolt 121, thereby unlocking the latching cover 120.

Optionally, latch housing 1321 includes a latch upper shell 13211 and a latch lower shell 13212. The latch lower case 13212 is mounted to the latch upper case 13211 by a screw.

It will be appreciated that the latch top 13211 and latch bottom 13212 have space for the latch 1322 to slide, and that the latch spring 1323 has one end abutting the latch 1322 and the other end abutting the latch top 13211 and/or latch bottom 13212.

In one embodiment, the end of the pin 1322 has a first inclined surface, the inner wall of the locking hole 1211 has a second inclined surface, and the pin 1322 extends into the locking hole 1211, and the first inclined surface abuts against the second inclined surface under the action of the ejecting assembly 133. That is, the ends of the locking pins 1322 are tapered. Since the ejecting member 133 is always ejected away from the fixing base 110, and the ejecting member 133 is always abutted against the latch tongue 121, the second inclined surface of the locking hole 1211 presses the first inclined surface of the latch pin 1322. The axial component of the force on the first inclined surface from the second inclined surface causes the locking pin 1322 to move upward by being pressed radially. In the electrically unlocked state, the latch 1322 can be moved out of the latch tongue 121, so that the latch cover 120 is unlocked.

It will be appreciated that when the pin 1322 is moved upwardly by the axial force component of the second inclined surface, the pin 1322 will retract into the latch housing 1321 and when the pin 1322 is extended by the pin spring 1323, the pin 1322 will extend out of the latch housing 1321. Of course, in other embodiments of the present invention, a special unlocking member may be provided so that latch 1322 may compress latch spring 1323 to move out of latching hole 1211 of latch bolt 121.

Illustratively, the angle of inclination of the first inclined surface is the same as the angle of inclination of the second inclined surface. Of course, in other embodiments of the present invention, the inclination angle of the first inclined plane may be greater than or less than the inclination angle of the second inclined plane. Thus, the second inclined surface may generate an axial component force that causes the locking pin 1322 to move upwardly under a radially compressive force.

In one embodiment, the control assembly 134 further includes a solenoid 1343, the solenoid 1343 is disposed in the locking housing 1321, and an iron core of the solenoid 1343 is extended to abut against an end of the locking pin 1322 away from the locking hole 1211. The control board 1341 further has a control module electrically connected to the wireless power supply module, the control module is electrically connected to the solenoid 1343, and the control module can control the iron core of the solenoid 1343 to retract after being powered on. It will be appreciated that the plunger of the solenoid 1343 is always in an extended state. The control module may effect motion actuation of the solenoid 1343 plunger. When the wireless power module energizes the control module, the control module may control the core retract solenoid 1343. When the control module is de-energized, the plunger of solenoid 1343 extends.

It will be appreciated that after electrical unlocking, the plunger of solenoid 1343 is radially compressed by the conical surface of locking pin 1322 due to the thrust of ejector slide 1333 due to the axial component of the compression force while the locking cap 120 is still in the closed position.

Alternatively, ejection of the lockout housing 120 may be accomplished by a higher pull-in solenoid 1343 or by pressing the lockout housing 120. When the attraction force of the solenoid 1343 is larger than the radial pressing force applied to the iron core, the locking cover 120 can be automatically ejected without pressing the locking cover 120. If the attraction force of the solenoid 1343 is smaller than the radial pressing force applied to the iron core, the iron core cannot be automatically sucked into the solenoid 1343, and at this time, the locking cover 120 needs to be pressed. Specifically, after the locking cover 120 is pressed, the ejecting slider 133 is separated from the locking pin 1322, at this time, the iron core is no longer subjected to the radial pressing force, the attraction force of the solenoid 1343 can attract the iron core back, and the locking cover 120 can be automatically ejected.

When the plunger 1343 extends, the plunger abuts against the latch 1322 to restrict the latch 1322 from retracting, the latch 1322 is located in the latching hole 1211 of the latch tongue 121 and cannot be removed, and the lock box 100 is locked. When the plunger of solenoid 1343 is retracted, latch 1322 may be moved out of latching aperture 1211 under the action of ejector assembly 133 and latching cassette 100 unlocked. When the locking cover 120 is in the closed position, the latch 1322 is moved upward by the second inclined surface by pressing the locking cover 120, and in order to ensure that the latch 1322 locks the latch 121 reliably, the latch 1322 is restricted from retracting into the locking housing 1321 by the iron core of the solenoid 1343 contacting the end of the latch 1322 away from the locking hole 1211, so that the latch 121 is ensured to be locked reliably.

Specifically, the locking cover 120 is in the closed position and the ejector assembly 133 is compressed and urged away from the fixed base 110. The latch tongue 121 of the locking cover 120 is pushed away from the fixing base 110 due to the contact with the eject assembly 133. Under the pushing force, the second inclined surface presses the first inclined surface of the latch pin 1322, and the latch pin 1322 receives the radial component force of the inclined surface of the latching hole 1211 of the latch bolt 121, so that the iron core of the solenoid 1343 receives a radial pressing force. Since the iron core can limit the upward movement of the latch 1322, it can be ensured that the latch 1322 locks the latch bolt 121 reliably.

Referring to fig. 6 and 7, when the lock-out box 100 is unlocked, the control assembly 134 is energized and the plunger cannot retract the solenoid 1343 due to the plunger being forced by the locking pin 1322. The first inclined surface of the locking pin 1322 is then moved away from the second inclined surface of the locking hole 1211 of the locking tongue 121 by pressing the locking cover 120. At this time, the lock pin 1322 receives no axial component force, and the lock pin 1322 is separated from the iron core of the solenoid 1343 by the lock pin spring 1323, and the iron core is sucked into the solenoid 1343. After the pressing force of the locking cover 120 is removed, the ejection assembly 133 moves away from the fixed seat 110 and pushes the latch bolt 121 away from the closed position. During the process of moving away, the first inclined surface of the latch 1322 receives the axial component force of the second inclined surface of the latching hole 1211 of the latch tongue 121 again, the latch 1322 is pressed and lifted to retract the latch housing 1321, and the latch spring 1323 is in a compressed state. The ejection assembly 133 slides to the end surface of the locking pin 1322, the locking pin 1322 cannot be returned to the locked position, and at the same time the locking cap 120 is pushed to the open position by the force of the ejection assembly 133. And (5) pulling out the computer key to finish power supply. The solenoid 1343 plunger is pushed out but cannot fully extend because it is blocked by latch 1322.

When the lock box 100 is locked, it can be implemented without a computer key. During closing, lock box 100 is depressed causing latch tabs 121 of lock box 100 to push eject assembly 133 away from the end faces of latch pins 1322. The latch 1322 is pushed out into the latching hole 1211 of the latch bolt 121 by the latch spring 1323, and at the same time, the plunger of the solenoid 1343 is fully extended to the end of the lock cylinder away from the latching hole 1211, and the latch 1322 is blocked by the plunger and cannot be retracted into the latch housing 1321 again.

Referring to fig. 3 to 5, in an embodiment, the control component 134 further includes a first magnetic steel 1344, the first magnetic steel 1344 is disposed in the locking housing 1321 and is close to the wireless key interface 13111, the computer key detects the first magnetic steel 1344, and the computer key supplies power to the wireless power supply module through the induction coil. First magnetic steel 1344 is used for power supply determination of the computer key. When the computer key approaches the first magnetic steel 1344, the computer key can detect the first magnetic steel 1344 and start to supply power to the control component 134. When the computer key does not detect the first magnetic steel 1344, the computer key does not supply power to the control component 134. Specifically, after the computer key is installed in the wireless key interface 13111, the computer key detects the first magnetic steel 1344 on the locking case 1321, starts to supply power and reads the identity of the locking box 100, and triggers the solenoid 1343 after the power is taken by the induction coil 1342 on the locking case 1321 and the identity of the control board 1341 is verified.

In one embodiment, the ejecting assembly 133 includes an ejecting slider 1333, a sliding rod 1331 and a sliding rod spring 1332, the sliding rod 1331 is disposed on the lock housing assembly 131, the sliding rod spring 1332 is sleeved on the sliding rod 1331, and the ejecting slider 1333 is slidably mounted on the sliding rod 1331 and abuts against the bolt 121. The sliding rod 1331 is fixedly disposed inside the lock case assembly 131, and it can be understood that the ejecting sliding block 1333 is in abutting engagement with the bolt 121 for ejecting the lock cover 120 in the unlocked state. Specifically, one end of the slide bar 1331 may be fixed to the rear cover 1312. A slide rod spring 1332 is located between the fixed seat 110 and the ejector slide 1333. The ejecting slider 1333 is in abutting fit with the latch tongue 121, and can move axially along the sliding rod 1331 under the action of the sliding rod spring 1332 to push the latch tongue 121 to move towards a direction away from the fixed seat 110, so as to open the locking cover 120. In the locked state, ejector slide 1333 is always in contact with tongue 121 by slide spring 1332, so that the second inclined surface of locking hole 1211 of tongue 121 and the first inclined surface of lock pin 1322 are locked.

Optionally, the ejecting assembly 133 further includes a retaining ring 1334, the retaining ring 1334 is disposed at an end of the ejecting slider 1333 away from the sliding rod spring 1332, and the retaining ring 1334 is used for limiting a sliding distance of the ejecting slider 1333. When ejecting slider 1333 moves against latch tongue 121 in a direction away from fixed seat 110 by slide bar spring 1332, ejecting slider 1333 stops sliding along slide bar 1331 when ejecting slider 1333 abuts against stop ring 1334. At this time, the latch cover 120 is in the open position. Illustratively, the number of the slide bars 1331 is two, and the two slide bars 1331 ensure that the ejecting slide block 1333 runs smoothly and avoids shaking. Accordingly, the number of the slide rod springs 1332 is also two. The stop 1334 is a split stop.

In an embodiment, the control assembly 134 further includes a second magnetic steel 1345, the second magnetic steel 1345 is disposed on the ejecting slider 1333 or the latch bolt 121, the control board 1341 has an electrically connected hall element and a latch bolt state detection module, and the hall element can detect the position of the second magnetic steel 1345 relative to the hall element to detect the position of the latch bolt 121 and feed back the position to the latch bolt state detection module. The second magnetic steel 1345 is used to detect the position of the latch tongue 121 to determine the state of the locking cover 120.

When the latch pin 1322 extends into the latching aperture 1211 of the latch tongue 121, the ejector slide 1333 compresses the slide spring 1332, and at this time, the second magnetic steel 1345 approaches the hall element, which is triggered, indicating that the latching cover 120 is in the closed position. After the hall element transmits the position information of the bolt 121 to the bolt state detection module, the computer key displays that the locking box 100 is in the non-unlocking state. When the latch 1322 is moved out of the latching hole 1211 of the latch 121, the ejecting slider 1333 drives the latch 121 to move away from the fixing base 110 under the action of the sliding rod spring 1332, and at this time, the second magnetic steel 1345 is away from the hall element, and the hall element is not triggered, indicating that the latching cover 120 is in the open position. Exemplarily, the second magnetic steel 1345 is disposed on the ejector slider 1333.

In one embodiment, the lock housing assembly 131 has an emergency unlocking hole, and the lock structure 130 further includes an emergency unlocking assembly 135 disposed on the lock housing assembly 131. The emergency unlock component 135 is used to unlock the lock box 100 in an emergency to save time and avoid accidents.

Specifically, the emergency unlocking assembly 135 includes an unlocking rotating shaft 1351, an unlocking push block 1352, a push block spring 1353 and an unlocking plug 1354, the unlocking rotating shaft 1351 is rotatably installed in the emergency unlocking hole, the unlocking push block 1352 is slidably installed in the lock housing assembly 131, the push block spring 1353 is installed between the unlocking push block 1352 and the lock housing assembly 131, the unlocking rotating shaft 1351 can drive the unlocking push block 1352 to slide when rotating, so that the unlocking push block 1352 pushes the iron core back to the solenoid 1343, and the unlocking plug 1354 is detachably installed in the emergency unlocking hole.

In case of electrical failure, the unlocking plug 1354 in the emergency unlocking hole can be opened, and the emergency unlocking key drives the unlocking rotating shaft 1351 and the unlocking push block 1352 to press the iron core of the solenoid 1343 into the solenoid 1343 to avoid the position of the lock pin 1322, so as to allow the lock pin 1322 to move out of the locking hole 1211 of the lock tongue 121, thereby mechanically unlocking the lock box 100.

In one embodiment, the unlocking rotating shaft 1351 has a notch, and the unlocking push block 1352 is installed in the notch. When the unlocking key drives the unlocking rotating shaft 1351 to rotate, the inner wall of the notch pushes the unlocking push block 1352 to move, and then the unlocking push block 1352 can push the iron core of the solenoid 1343, so that the iron core is pressed into the solenoid 1343. In other embodiments of the present invention, the unlocking rotating shaft 1351 has an arc-shaped protrusion, and when the unlocking rotating shaft 1351 rotates, the protrusion may abut against the unlocking pushing block 1352. Thus, when the unlocking rotating shaft 1351 rotates, the protrusion gradually contacts the unlocking push block 1352, and the unlocking push block 1352 pushes the iron core of the solenoid 1343, so that the iron core is pressed into the solenoid 1343. Illustratively, the projection is a cam, or the outer profile of the projection is a major arc. Of course, the unlocking rotating shaft 1351 and the unlocking push block 1352 can also be matched with other structures which can enable the unlocking push block 1352 to do linear motion.

In one embodiment, the unlocking push block 1352 has a pushing portion by which the unlocking push block 1352 abuts the iron core. The pushing part is plate-shaped and is used for avoiding limiting the locking pin 1322. An unlocking push block 1352 is located on the side of the latch 1322 remote from the solenoid 1343. This ensures that the unlocking push block 1352 accurately presses the plunger into the solenoid 1343. After the unlocking push block 1352 presses the iron core into the solenoid 1343, the locking pin 1322 abuts against the unlocking push block 1352, and in order to prevent the unlocking push block 1352 from affecting the movement of the locking pin 1322 out of the locking hole 1211, the unlocking push block 1352 has a pushing portion through which the iron core is pushed. Further, the plate-shaped pushing portion has a thickness smaller than that of the core. Thus, the pushing portion does not limit the locking pin 1322, and the locking pin 1322 may move out of the locking hole 1211 of the locking tongue 121 to unlock the locking cover 120. Optionally, the thickness of the pushing part is 1/4-1/2 of the thickness of the iron core.

Referring to fig. 6 and 7, when the locking box 100 of the present invention is unlocked, a computer key is inserted into the wireless key port 13111 of the lock housing 1311.

After the pressing force of the locking cover 120 is removed, the ejecting slider 1333 is separated from the fixed seat 110 by the sliding rod spring 1332, and pushes the locking cover 120 to be separated from the closed position. During the process of moving away, the first inclined surface of the latch 1322 receives the axial component force of the second inclined surface of the latching hole 1211 of the latch tongue 121 again, the latch 1322 is pressed into the latch housing 1321, and the latch spring 1323 is in a compressed state. The eject slide 1333 slides to the end surface of the lock pin 1322, and the lock pin 1322 cannot be returned to the locked position, while the lock cover 120 is pushed to the open position by the force of the eject slide 1333. And (5) pulling out the computer key to finish power supply. The solenoid 1343 plunger is pushed out but cannot fully extend because it is blocked by latch 1322.

When the lock box 100 is locked, movement of the lock housing 120 to the closed position is achieved without the need for a computer key. During closing, the locking tongue 121 of the locking cover 120 pushes the ejector slide 1333 away from the locking pin 1322. The latch 1322 is pushed out to the latching hole 1211 of the latch bolt 121 by the latch spring 1323, and at the same time, the plunger of the solenoid 1343 is fully extended to the end face of the latch 1322, and the latch 1322 is retracted and blocked from being pushed into the latching housing 1321 again.

When the locking box 100 is unlocked emergently, the unlocking plug 1354 in the emergency unlocking hole is pulled out, and an emergency unlocking key is inserted and rotated. The unlocking shaft 1351 pushes the unlocking push block 1352 by the emergency unlocking key, the push block spring 1353 is compressed, and the iron core of the solenoid 1343 is pushed into the solenoid 1343 by the force of the unlocking push block 1352. The ejector slide 1333 moves away from the fixed base 110 under the action of the slide rod spring 1332 and pushes the latch tongue 121 of the locking cover 120 away from the closed position. During the distancing process, the first inclined surface of the latch 1322 receives the axial component force of the second inclined surface of the latching hole 1211 of the latch tongue 121, the latch 1322 is pressed into the latch housing 1321, and the latch spring 1323 is in a compressed state. The eject slide 1333 slides to the end surface of the lock pin 1322, and the lock pin 1322 cannot be returned to the locked position, while the lock cover 120 is pushed to the open position by the force of the eject slide 1333.
