Description

Technical Field

[0001] This invention relates to a cabinet lock, and more particularly to an electronic cabinet lock. Background Technology

[0002] Most existing cabinet locks used for server racks are mechanical key locks, which have a single unlocking method. If the key is forgotten, lost, or the lock cylinder malfunctions, it is impossible to unlock or lock, causing inconvenience. Furthermore, mechanical key locks make it difficult to implement information-based access control management of unlocking time and personnel. To solve the inconvenience caused by mechanical key locks, cabinet locks with electronic functions have emerged on the market.

[0003] See Figure 1 Chinese invention patent publication number CN113137145A discloses a cabinet lock 9, which has both electronic and mechanical unlocking methods. The cabinet lock 9 includes a mounting base 91, a handle 92 rotatably mounted on the mounting base 91, a torsion spring 93 disposed between the mounting base 91 and the handle 92, a Bluetooth communication module (not shown) disposed within the mounting base 91, and an electromagnetic lock 94 disposed on the mounting base 91 and signal-connected to the Bluetooth communication module. The handle 92 has a locking seat 921, a lock cylinder 922 passing through the locking seat 921, and a locking piece 923 connected to the lock cylinder 922. The locking seat 921 has a slot 924 and a locking hole 925 adjacent to the slot 924 for the locking piece 923 to pass through vertically. The lock cylinder 922 can drive the locking piece 923 to move vertically within the locking hole 925. The electromagnetic lock 94 has a body 941, an output shaft 942 that can be inserted downward into the slot 924 from the body 941, a baffle 943 disposed on the output shaft 942, and a return spring 944 disposed between the baffle 943 and the body 941. The locking piece 923 can be used to prevent the output shaft 942 from dislodging backward from the slot 924.

[0004] When unlocking with an electronic lock, the electromagnetic lock 94 is activated by connecting a mobile phone to the Bluetooth communication module, causing the output shaft 942 to move upward and compressing the return spring 944. At this time, after the output shaft 942 disengages from the slot 924, the handle 92 disengages from the mounting base 91 under the action of the torsion spring 93. The return spring 944 then releases its compressive force to push against the stop plate 943, causing the output shaft 942 to return downward. When locking, the handle 92 is pushed towards the mounting base 91, causing the output shaft 942 to contact the locking plate 923 and move upward, compressing the return spring 944. When the output shaft 942 moves to a position above the slot 924, the return spring 944 releases its compressive force to push against the stop plate 943, causing the output shaft 942 to insert downward into the slot 924. The output shaft 942 is then stopped by the locking plate 923, thus completing the locking process.

[0005] When unlocking using a mechanical lock, inserting a key into the lock cylinder 922 and turning it causes the locking plate 923 to move downwards, disengaging the output shaft 942 from the stop of the locking plate 923, and causing the handle 92 to disengage from the mounting base 91 under the action of the torsion spring 93. When locking, pushing the handle 92 toward the mounting base 91 causes the output shaft 942 to move directly into the slot 924. Then, turning the key causes the locking plate 923 to move upwards and reset, stopping the output shaft 942 and preventing it from coming out.

[0006] However, under prolonged use of electronic unlocking, the return spring 944 is prone to elastic fatigue, making it difficult to return the output shaft 942 downwards. This results in the output shaft 942 not being securely inserted into the slot 924. Furthermore, during unlocking and locking, the output shaft 942 continuously contacts the locking seat 921 and the locking plate 923, easily causing wear on the output shaft 942 and potentially damaging the electromagnetic lock 94. In addition, when operating the mechanical lock for locking, the user needs to hold the handle 92 against the mounting base 91 with one hand to prevent the torsion spring 93 from pulling the handle 92 away from the mounting base 91, while the user's other hand must simultaneously turn the key to move the locking plate 923 upwards to return it to its original position and stop the output shaft 942, making the operation inconvenient. Summary of the Invention

[0007] The purpose of this invention is to provide an electronic cabinet lock that is not easily damaged and is easy to operate.

[0008] This invention relates to an electronic cabinet lock, comprising a base unit, a handle unit, a clutch unit, a control unit, and a lock cylinder. The base unit includes a mounting base and a pivot rotatably disposed on the mounting base. The mounting base has a receiving groove. The handle unit includes a handle pivotally connected to the pivot and detachably disposed in the receiving groove; a torsion spring disposed between the handle and the pivot; a pivot member oscillatingly disposed at the end of the handle opposite to the pivot; a first magnetic element disposed at the end of the handle adjacent to the pivot member; and a second magnetic element disposed on the pivot member and constantly attracted by the first magnetic element. The torsion spring causes the handle to maintain a constant tendency to detach from the receiving groove. The clutch unit is disposed within the mounting base and includes a stop member that is driven to move in a vertical direction. The stop member can engage with the front side of the upper end of the pivot member in a forward / backward direction perpendicular to the vertical direction. The control unit is disposed on the handle and is used to control the movement of the stop member of the clutch unit in the vertical direction. The lock cylinder is disposed in the receiving groove and located below the handle. The lock cylinder includes a bolt that can move in the vertical direction and a locking core that can drive the bolt to move up and down. The bolt can abut against the front side of the lower end of the pivot member. The locking core has a keyhole communicating with the outside.

[0009] The electronic cabinet lock of the present invention has a pivot member having a pivot portion pivotally mounted on the handle and for the second magnetic member to be disposed thereon, an upper locking portion extending upward from the pivot portion, and a lower locking portion extending downward from the pivot portion. The upper locking portion can abut against the rear side of the stop member in the front-back direction, and the lower locking portion can abut against the rear side of the lock tongue in the front-back direction.

[0010] The electronic cabinet lock of the present invention further includes a pressure plate disposed in the mounting base and abutting against the front side of the stop member. The pressure plate has a downwardly opening groove that allows the upper locking part to pass through.

[0011] The electronic cabinet lock of the present invention has a handle having a body that is pivotally connected to the rotating shaft and extends along the vertical direction, and a positioning block that extends rearward from one end of the body away from the rotating shaft along the vertical direction. The positioning block includes a central portion for the first magnetic element to be disposed, and two protruding arm portions that protrude from both sides of the central portion and are pivotally disposed for the pivot portion of the pivoting element.

[0012] The electronic cabinet lock of the present invention has a central portion having a first mounting groove that opens rearward and allows the first magnetic component to be embedded, and a pivot portion having a second mounting groove that opens toward the first mounting groove and allows the second magnetic component to be embedded.

[0013] The electronic cabinet lock of the present invention has a handle that has a through groove extending through the body along the front-back direction. The control unit includes a sensor housing embedded in the through groove and connected to the outside, and a control circuit board electrically connected to the sensor housing. The control circuit board can control the stop member of the clutch unit to move along the up-down direction.

[0014] The electronic cabinet lock of the present invention further includes a clutch unit comprising a driver disposed in the mounting base and activated by the control unit, an outer cylinder disposed below the driver, an inner cylinder slidably disposed in the outer cylinder along the vertical direction, a worm gear located in the inner cylinder and rotated by the driver, and an elastic member connected between the inner cylinder and the worm gear, wherein the stop member is connected to the bottom surface of the inner cylinder.

[0015] The electronic cabinet lock of the present invention has a driver having an output shaft that can drive the worm gear to rotate. The worm gear has a rod portion sleeved on the output shaft and a worm tooth portion formed on the outer peripheral surface of the rod portion. The upper end of the elastic member is slidably disposed on the worm tooth portion, and the lower end of the elastic member is fixed to the bottom of the inner cylinder.

[0016] The electronic cabinet lock of the present invention has an upper locking part having a first inclined surface located on the rear side and tilted from top to bottom and rearward, and a stop member having a second inclined surface located on the front side and tilted from top to bottom and rearward, corresponding to the first inclined surface.

[0017] The electronic cabinet lock of the present invention has a locking tongue having a third inclined surface located on the front side and tilted from bottom to top and backward.

[0018] The beneficial effects of this invention are as follows: When the electronic cabinet lock is locked or unlocked, the pivot member swings after being blocked by either the stop member or the latch. The pivot member then swings back to its original position under the constant attraction of the first magnetic member by the second magnetic member. With long-term use, the first and second magnetic members can maintain their magnetic attraction, allowing the pivot member to operate normally. In addition, when locking, the user only needs to push the handle back into the receiving groove with one hand to make the pivot member block against the stop member and the rear side of the latch, thus completing the locking. The operation is quite convenient. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] See Figures 2 to 4 One embodiment of the electronic cabinet lock 1 of the present invention is applicable to a door panel (not shown) installed in a cabinet (not shown). The electronic cabinet lock 1 can be electronically unlocked via a card (not shown) or wirelessly controlled, or mechanically unlocked via a key (not shown).

[0032] The electronic cabinet lock 1 includes a base unit 2, a handle unit 3, a clutch unit 4, a control unit 5, and a lock cylinder 6.

[0033] The mounting unit 2 includes a mounting base 21 installed on the front side of the door panel along the front-rear direction X, a back plate 22 installed on the rear side of the door panel and locked to the mounting base 21, a pivot 23 rotatably disposed on the mounting base 21 about an axis L parallel to the front-rear direction X, a locking plate 24 disposed on the pivot 23 and rotating synchronously with the pivot 23, and a pressure plate 25 disposed within the mounting base 21 and adjacent to the clutch unit 4. The mounting base 21 has a receiving groove 211 extending along the vertical direction Y perpendicular to the front-rear direction X. The pressure plate 25 has a downwardly opening groove 251. The locking plate 24 can abut against the inside of the cabinet to secure the door panel to the cabinet.

[0034] The grip unit 3 includes a handle 31 pivotally mounted on the pivot 23 and detachably disposed in the receiving groove 211; a torsion spring 32 disposed between the handle 31 and the pivot 23; a pivot member 33 oscillatingly disposed at one end of the handle 31 opposite to the pivot 23 in the vertical direction Y; a first magnetic member 34 disposed at one end of the handle 31 adjacent to the pivot member 33; and a second magnetic member 35 disposed on the pivot member 33 and constantly attracted by the first magnetic member 34. The torsion spring 32 keeps the handle 31 constantly detached from the receiving groove 211.

[0035] The handle 31 has a body 311 pivotally connected to the pivot 23 and extending along the vertical direction Y, a positioning block 312 extending rearward from one end of the body 311 away from the pivot 23 along the vertical direction Y, and a through groove 313 penetrating the body 311 along the front-rear direction X. The positioning block 312 includes a central portion 314 and two protruding arm portions 315 protruding from both sides of the central portion 314. The central portion 314 has a rearward-opening first mounting groove 316 for the first magnetic element 34 to be embedded. The protruding arm portions 315 are used for the pivot member 33 to be pivotally mounted.

[0036] See Figures 3 to 5 The pivot member 33 has a pivot portion 331 pivotally mounted on the protruding arm portions 315, an upper locking portion 332 extending upward from the pivot portion 331, and a lower locking portion 333 extending downward from the pivot portion 331. The pivot portion 331 has a second mounting groove 334 that opens toward the first mounting groove 316 and allows the second magnetic member 35 to be embedded. The upper locking portion 332 has a first inclined surface 335 located on the rear side and sloping downward and backward from top to bottom.

[0037] The clutch unit 4 is disposed within the mounting base 21 and includes a driver 41, an outer cylinder 42 disposed below the driver 41, an inner cylinder 43 slidably disposed within the outer cylinder 42 in the vertical direction Y, a worm gear 44 located within the inner cylinder 43 and driven to rotate by the driver 41, an elastic member 45 connecting the inner cylinder 43 and the worm gear 44, and a stop member 46 connected to the bottom surface of the inner cylinder 43 and abutting against the rear side of the pressure plate 25. The driver 41 is a motor and has an output shaft 411 capable of driving the worm gear 44 to rotate. The worm gear 44 has a rod portion 441 sleeved on the output shaft 411 and a worm gear portion 442 formed on the outer peripheral surface of the rod portion 441. The elastic member 45 is a tension spring, the upper end of which is slidably disposed on the worm gear portion 442, and the lower end of which is fixed to the bottom of the inner cylinder 43. The stop 46 has a second inclined surface 461 located on the front side and inclined from top to bottom and rear, which corresponds to the first inclined surface 335 of the upper locking part 332.

[0038] See Figure 5 and Figure 6 The driver 41 drives the output shaft 411 to rotate in the forward direction. The worm gear 44 is driven by the output shaft 411 and rotates synchronously in the forward direction. The upper end of the elastic member 45 moves upward along the worm gear 442, and the lower end of the elastic member 45 is stretched, pulling the inner cylinder 43 upward. The stop member 46 moves upward with the inner cylinder 43. Conversely, when the driver 41 drives the output shaft 411 to rotate in the reverse direction, the worm gear 44 is driven by the output shaft 411 and rotates synchronously in the reverse direction. The upper end of the elastic member 45 moves downward along the worm gear 442, and the lower end of the elastic member 45 is compressed, pushing the inner cylinder 43 downward. The stop member 46 moves downward with the inner cylinder 43. By controlling the forward and reverse rotation of the output shaft 411 of the driver 41, the up and down movement of the stop member 46 can be controlled.

[0039] The control unit 5 includes a sensor housing 51 embedded in the slot 313 and a control circuit board 52 electrically connected to the sensor housing 51. The control circuit board 52 can control the forward and reverse rotation of the output shaft 411 of the driver 41, thereby controlling the up and down movement of the stop member 46. The sensor housing 51 can sense and receive identification data from the card, and after receiving the identification data, transmit an unlocking command to the control circuit board 52, causing the control circuit board 52 to control the forward rotation of the output shaft 411 of the driver 41.

[0040] See Figure 11The electronic cabinet lock 1 also includes a power supply unit 7. The power supply unit 7 includes a microcontroller 71 signal-connected to the control circuit board 52, a main power supply 72 electrically connected to the microcontroller 71, a backup power supply 73 electrically connected to the microcontroller 71, and a power control module 74 electrically connected to the main power supply 72 and the backup power supply 73. The main power supply 72 and the backup power supply 73 can respectively supply power to the microcontroller 71, the control circuit board 52, the sensor housing 51, and the driver 41. The power control module 74 can detect the voltage of the main power supply 72 and the backup power supply 73, and automatically switch the power supply to the one with the higher voltage. The microcontroller 71 can detect whether the main power supply 72 is supplying power and can detect the remaining power of the backup power supply 73.

[0041] In this embodiment, the sensing housing 51 and the card communicate using Radio Frequency Identification (RFID) technology. Alternatively, the operator can also use a mobile device, such as a smartphone, to wirelessly communicate via Bluetooth, sending an unlock signal to the sensing housing 51. This causes the sensing housing 51 to transmit the unlock command to the control circuit board 52, controlling the output shaft 411 of the driver 41 to rotate forward.

[0042] The lock cylinder 6 is disposed in the receiving groove 211 and located below the handle 31. The lock cylinder 6 includes a bolt 61 that can move along the vertical direction Y, and a lock core 62 that can drive the bolt 61 to move up and down. The bolt 61 maintains a constant upward movement and has a third inclined surface 611 located on the front side and tilted from bottom to top and backward. The lock core 62 has a keyhole 621 communicating with the outside. When a person inserts the key into the keyhole 621 and turns it, the lock core 62 can be unlocked. After the lock core 62 is unlocked, it can be pressed backward to drive the bolt 61 to move downward. When the lock core 62 is not pressed, it can automatically return to its forward position. When the lock core 62 is locked, it cannot be pressed backward, but the bolt 61 can still be pushed and moved downward. When the bolt 61 is not pushed, it can automatically return to its upward position. The lock cylinder 6 is a conventional mechanical lock structure and will not be described in detail here.

[0043] The electronic cabinet lock 1 can switch between a locked state and an unlocked state.

[0044] See Figure 2 , Figure 4 and Figure 5When the electronic cabinet lock 1 is in the locked state, the handle 31 is located in the receiving groove 211, the upper locking portion 332 of the pivot 33 is engaged with the rear side of the stop 46 in the front-rear direction X, and the lower locking portion 333 of the pivot 33 is engaged with the rear side of the latch 61 in the front-rear direction X. At this time, the body 311 is subjected to the action of the torsion spring 32, and the end of the body 311 on which the pivot 33 is pivotally mounted always tends to move forward away from the receiving groove 211, so that the upper locking portion 332 and the lower locking portion 333 of the pivot 33 are tightly engaged with the stop 46 and the latch 61 respectively, thereby making the stop 46 tightly clamped between the pressure plate 25 and the upper locking portion 332.

[0045] See Figure 6 When electronic unlocking is used, the operator can use the card to sense the sensor housing 51, or use a smartphone to send the unlock signal to the sensor housing 51, causing the sensor housing 51 to send the unlock command to the control circuit board 52. The control circuit board 52 controls the output shaft 411 of the driver 41 to rotate forward, thereby causing the stop member 46 to move upward. At this time, because the upper locking part 332 of the pivot member 33 has disengaged from the stop member 46, the handle 31 can be supported by the torsion spring 32 (see reference). Figure 4 The handle 31 moves forward away from the receiving groove 211 due to the action of the locking tongue 61. During the process of the handle 31 moving forward away from the receiving groove 211, the lower locking part 333 of the pivot 33 is first blocked by the rear side of the locking tongue 61, causing the upper locking part 332 to swing forward and pass through the groove 251 of the pressure plate 25. After the lower locking part 333 moves forward away from the locking tongue 61, the upper locking part 332 swings back to its original position because the second magnetic element 35 provided on the pivot 331 is attracted by the first magnetic element 34.

[0046] See Figure 2 and Figure 7 When mechanical unlocking is used, the operator can unlock the lock cylinder 62 by inserting the key into the lock hole 621 and turning it, then pressing the lock cylinder 62 to move the bolt 61 downward, causing the lower locking part 333 to disengage from the latch on the rear side of the bolt 61. At this time, because the lower locking part 333 has disengaged from the latch 61, the handle 31 can be pushed forward from the receiving groove 211 by the action of the torsion spring 32. During the process of the handle 31 moving forward from the receiving groove 211, the upper locking part 332 of the pivot member 33 is first latched by the rear side of the stop member 46, causing the lower locking part 333 to swing forward until the upper locking part 332 disengages from the stop member 46. Then, because the second magnetic member 35 provided on the pivot member 331 is attracted by the first magnetic member 34, the lower locking part 333 swings backward to return to its original position.

[0047] Under normal circumstances, operators primarily use electronic unlocking. However, in the event of a power outage or a malfunction of the clutch unit 4, when electronic unlocking is not possible, operators can still mechanically unlock the door by using the key to unlock the lock cylinder 62.

[0048] See Figure 8 and Figure 9 When the electronic cabinet lock 1 switches to the unlocked state after being unlocked electronically or mechanically, the handle 31 moves away from the receiving slot 211. The operator can rotate the handle 31 around the axis L to drive the rotating shaft 23 and the lock plate 24 to rotate synchronously, so that the lock plate 24 is not stuck inside the cabinet, and the door can be opened. When electronic unlocking is used, the control circuit board 52 controls the output shaft 411 of the driver 41 to rotate forward, causing the stop 46 to move upward. After a preset time, the control circuit board 52 automatically controls the output shaft 411 of the driver 41 to rotate in the reverse direction, thereby causing the stop 46 to move downward. Therefore, after the electronic cabinet lock 1 switches to the unlocked state, the stop 46 will move downward to the position of the locked state after the preset time.

[0049] It is worth noting that when using electronic unlocking, if the control circuit board 52 controls the output shaft 411 of the driver 41 to rotate in the forward direction and attempts to move the stop 46 upward, the stop 46 cannot move upward smoothly because it is tightly clamped between the pressure plate 25 and the upper locking part 332. In this case, the operator only needs to gently press the handle 31, causing the handle 31 to move the pivot 33 slightly backward, and the stop 46 can then move upward smoothly, allowing the handle 31 to disengage from the receiving slot 211 under the action of the torsion spring 32. This foolproof mechanism is added to the electronic cabinet lock 1 so that when the operator accidentally uses wireless communication to operate the electronic unlocking remotely, there is no need to worry that the handle 31 will easily disengage from the receiving slot 211. Furthermore, since the control circuit board 52 controls the output shaft 411 to rotate in the forward direction, after the preset time, the control circuit board 52 will automatically control the output shaft 411 to rotate in the reverse direction, so that the stop 46 will not continue to move upward, but will remain in the position of being locked against the upper locking part 332, ensuring that the electronic cabinet lock 1 is in the locked state.

[0050] See Figure 10When switching the electronic cabinet lock 1 from the unlocked state to the locked state, the operator needs to press the handle 31 backward to overcome the action of the torsion spring 32, so that the handle 31 moves backward and retracts into the receiving groove 211. During the backward movement of the handle 31, the rear side of the lower locking part 333 of the pivot 33 abuts against the third inclined surface 611, causing the upper locking part 332 to swing backward, pass through the groove 251 and avoid the stop 46, until the lower locking part 333 passes backward through the third inclined surface 611, the second magnetic member 35 is attracted by the first magnetic member 34 and causes the upper locking part 332 to swing forward and reset, thereby causing the upper locking part 332 to abut against the rear side of the stop 46 (e.g., Figure 4 As shown, the lower locking part 333 abuts against the rear side of the locking tongue 61 to lock the electronic cabinet lock 1. During the process of the lower locking part 333 abutting against the third inclined surface 611 and moving backward, the locking tongue 61 moves downward due to the push of the lower locking part 333 until the lower locking part 333 has completely passed the third inclined surface 611, at which point the locking tongue 61 automatically returns to its upward position.

[0051] Because manufacturing tolerances are unavoidable in the components, during the rearward movement of the handle 31, the rear side of the lower locking portion 333 of the pivot 33 abuts against the third inclined surface 611, causing the upper locking portion 332 to swing rearward. When passing through the groove 251, the first inclined surface 335 of the upper locking portion 332 may contact the second inclined surface 461 of the stop member 46. Due to the correspondence between the shapes of the first inclined surface 335 and the second inclined surface 461, the upper locking portion 332 can slightly push the stop member 46 upward to continue swinging backward. When the stop member 46 is pushed upward, it causes the inner cylinder 43 to compress the elastic member 45 upward until the upper locking portion 332 disengages from the stop member 46. Then, the elastic member 45 pushes downward against the inner cylinder 43, causing the stop member 46 to return to its original position.

[0052] It is worth noting that regardless of whether electronic or mechanical unlocking is used, the electronic cabinet lock 1 is locked through the aforementioned locking operation, and the operator can complete the operation with only one hand. When locking after mechanical unlocking, since the lock core 62 is still in the unlocked state, it must also be locked. The operator can choose to lock the lock core 62 first and then perform the locking operation, or perform the locking operation first and then lock the lock core 62. Regardless of the order, the operator can complete the locking operation with one hand, which is quite convenient.

[0053] In summary, the electronic cabinet lock 1 of the present invention, by means of the second magnetic element 35 embedded in the pivot portion 331 of the pivot member 33, can be constantly attracted by the first magnetic element 34 embedded in the central portion 314. Therefore, regardless of whether electronic unlocking, mechanical unlocking, or locking operations are performed, when the pivot member 33 is blocked by the stop member 46 or the lock tongue 61 and swings back and forth, the first magnetic element 34 can attract the second magnetic element 35, so that the pivot member 33 can be attracted by the first magnetic element 34. When the swinging component 33 returns to its original position, the first magnetic component 34 and the second magnetic component 35 can maintain their magnetic attraction over a long period of use, allowing the swinging component 33 to operate normally. In addition, when locking, the user only needs to push the handle 31 back into the receiving groove 211 with one hand to lock the upper locking part 332 against the rear side of the stop 46 and the lower locking part 333 against the rear side of the locking tongue 61, thus completing the locking. The operation is quite convenient, so the purpose of the present invention can indeed be achieved.

[0054] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
