Description

Clutch mechanism and its electric lock

The present invention relates to a clutch mechanism and its associated electric lock, and more particularly to a clutch mechanism that utilizes a combination of keys and a rotating card member to drive the clutch to unlatch and its associated electric lock.

In general, the electric lock has a combination of keys for the user to use the key to drive the key combination, and then cooperate with the clutch mechanism coupled to the key combination to achieve manual unlapping. The conventional clutch mechanism utilizes a plurality of cams to convert the rotation action of the combination of the keys into the clutching member of the card member, and cooperates with the internal connecting member to make the card member engage with the latch assembly or separate from the latch assembly. . However, the conventional clutch mechanism needs to use a plurality of cams and connecting members, and has a large number of parts and a complicated structure, so that more manpower is required for assembly during production, thereby increasing the production cost of the electric lock, thereby reducing the electric lock in the market. The price competitive advantage.

Accordingly, the present invention provides a clutch mechanism having a simple structure and its associated electric lock to solve the above problems.

The invention discloses a clutch mechanism comprising a rotating card member, a clutch member and a key combination. The rotating clip has at least one first pushed structure. The clutch member has at least one second pushed structure, and the at least one second pushed structure abuts against the at least one first pushed structure. The key combination is configured to drive the rotating card member to rotate toward a first direction and the at least one first pushed structure for driving the rotating member to cooperate with the at least one second pushed structure of the clutch member to enable The clutch member is displaceable relative to the rotating clamp member to urge the clutch member to an unlatched position.

The invention further discloses an electric lock comprising a handle device, a latch assembly and a clutch mechanism. The handle device is rotatable relative to a long axis and the clutch mechanism is configured to transmit the torque experienced by the handle device to the latch assembly to thereby disengage the latch assembly. The clutch mechanism includes a rotating card member, a clutch member and a key combination. The rotating clamping member is rotatable relative to the major axis, the clutch member being rotatable relative to the major axis and movable along the major axis for movably abutting the rotating clamping member. The key combination is used to drive the rotating card member to rotate toward a first direction, and the rotating card member is rotated against the clutch member to rotate along the long axis relative to the rotating card member, thereby pushing the clutch member To the unlatched position.

In summary, the key combination of the present invention is coupled to the rotating card member, so that when the user drives the key combination with the key member, the key combination can directly drive the rotating card member. At this time, since the first pushed structure on the rotating engaging member abuts against the second pushed structure on the clutch member, the engaging member is rotated by the cooperation of the first pushed structure and the second pushed structure. The clutch member can be pushed, so that the clutch member can be displaced relative to the rotating card member to be engaged with the latch module. In this way, the structural design of the present invention is simplified, and only the rotating card member can be used to convert the rotating action of the key combination into the clutch moving member of the clutch member, which not only saves material cost of the object but also simplifies the assembly process, so The production does not require more manpower for assembly, thereby saving the production cost of the electric lock, thereby increasing the price competitive advantage of the electric lock in the market.

Please refer to FIG. 1. FIG. 1 is a schematic view showing the components of the electric lock 30 according to an embodiment of the present invention. As shown in FIG. 1, the electric lock 30 can be mounted on a door panel 32. The electric lock 30 is used to latch the door panel 32 to a wall 31 or to unlatch the door panel 32 from the wall surface 31. 32 is correspondingly in a latched state or an unlatched state. Please refer to FIG. 1 and FIG. 2 . FIG. 2 is a schematic diagram of components of the electric lock 30 according to another embodiment of the present invention. As shown in Figures 1 and 2, the electric lock 30 includes a transmission mechanism 34. In addition, the transmission 34 includes an electrical actuator 36 that serves as a source of power for the electric lock 30. Further, the electric lock 30 further includes an input unit 38 for inputting a signal such as a cryptographic signal. In this embodiment, the input unit 38 can be an ammonium bond device, but is not limited thereto. For example, the input unit 38 can also be a touch panel. In other words, any input device that can be used to input the signal is within the scope of the present invention.

It is worth mentioning that the electric lock 30 further includes a control unit 40 coupled to the input unit 38 and the electric actuator 36. When the user wants to open the door 32, the input unit 38 is first used to input the signal to the control unit 40. Then, when the signal input by the input unit 38 matches an authorization signal, the control unit 40 controls the electric actuator 36 to be energized to drive the transmission mechanism 34 to perform subsequent unlatching or the like. In addition, the transmission mechanism 34 further includes a first rotating wheel 42 and a second rotating wheel 44. The first rotating wheel 42 is used to transmit the torque output by the electric actuator 36, and the first rotating wheel 42 has an axial direction A. The second rotating wheel 44 is arranged adjacent to the first rotating wheel 42 in the axial direction A such that the torque output by the electric actuator 36 can be along the axial direction A to the first rotating wheel 42 and the second rotating wheel. 44 passes.

Please refer to FIG. 3 and FIG. 4 . FIG. 3 is a schematic diagram showing the explosion of the components of the first rotating wheel 42 and the second rotating wheel 44 according to the embodiment of the present invention. FIG. 4 is a first rotating wheel 42 and a second embodiment of the present invention. A schematic diagram of the explosion of the rotating wheel 44 at another viewing angle. As shown in FIGS. 3 and 4, the first rotating wheel 42 has a rotating recess 421, the second rotating wheel 44 has a rotating shaft portion 441, and the rotating shaft portion 441 is rotatably disposed in the rotating recess 421. in. In addition, the transmission mechanism 34 further includes an interference mechanism 46 disposed between the first rotating wheel 42 and the second rotating wheel 44. In this embodiment, the interference mechanism 46 includes two card slots 461 and a receiving slot 463. Each of the card slots 461 is formed on the outer periphery of the rotating concave portion 421 of the first rotating wheel 42 and has a part of a circular arc concave surface. The receiving groove 463 is formed on an end surface of the rotating shaft portion 441 of the second rotating wheel 44. Referring to FIG. 5, FIG. 5 is a cross-sectional view showing the components of the first rotating wheel 42, the second rotating wheel 44, and the interference mechanism 46 according to the embodiment of the present invention. As shown in FIG. 5, when the first rotating wheel 42, the second rotating wheel 44, and the interference mechanism 46 are assembled in the axial direction A of the rotating shaft portion 441, the interference mechanism 46 can be disposed on the first rotating wheel 42 and The second rotating wheel 44 is disposed between the second rotating slots 44 and the receiving slots 463 are located inside the respective slots 461. Further, the accommodation groove 463 is formed with two openings 465 in a radial direction B perpendicular to the axial direction A of the rotation shaft portion 441.

In addition, the interference mechanism 46 further includes two fasteners 467 and an elastic member 469. Each of the fasteners 467 has a part of the arcuate convex surface, and each of the fasteners 467 is located in the receiving groove 463 and is detachably engaged in the card slot 461. The elastic member 469 is disposed in the accommodating groove 463. In addition, when the elastic member 469 is disposed in the accommodating groove 463, the elastic member 469 cannot occupy the groove because the fastener 467 occupies a part of the space of the accommodating groove 463. The 463 is released, but instead is pushed by the fastener 467 to cause the elastic member 469 to elastically deform. Therefore, the elastic member 469 can respectively apply an elastic force to the fastener 467, so that the respective fasteners 467 are respectively pushed outward in the direction indicated by the arrow in the radial direction B. As a result, a portion of the arcuate surface of each of the fasteners 467 contacts a portion of the arcuate concave surface of the card slot 461 via the opening 465, thereby being engaged in the corresponding card slot 461 (as shown in FIG. 5). Thereby, the first rotating wheel 42 and the second rotating wheel 44 can interfere with each other by the respective reinforcing members 467, so that the torque output by the electric actuating member 36 can be along the axial direction A of the first rotating wheel 42. A rotating wheel 42 and a second rotating wheel 44 are transferred between each other. In this embodiment, the elastic member 469 is a C-shaped spring, and the receiving groove 463 is a C-shaped groove, and the two ends of the C-shaped spring are elastically abutted in the radial direction B, respectively. Card firmware 467. In addition, in practice, each of the fasteners 467 can be a roller structure, and each of the slots 461 can be a corresponding semi-cylindrical groove (as shown in FIG. 3 and FIG. 4).

In summary, the number of the card slots 461 and the fasteners 467 may not be limited to those described in this embodiment. For example, the interference mechanism 46 of the present invention may also include only one fastener 467 and a corresponding one of the slots 461. Alternatively, the interference mechanism 46 may further include two elastic members 469 and two receiving grooves 463. The elastic members 469 are respectively disposed in the receiving grooves 463, and the two ends of the elastic members 469 respectively abut the fasteners. 467. In other words, the interference mechanism 46 can also include four fasteners 467 and four corresponding card slots 461, that is, the interference mechanism 46 of the present invention includes at least one card slot 461, at least one receiving slot 463, and at least one card. Firmware 467 and at least one elastic member 469. In other words, as long as the card slot 461, the receiving groove 463, the fastener 467, and the elastic member 469 are disposed, the first rotating wheel 42 and the second rotating wheel 44 can interfere with each other, thereby making the first rotating wheel 42. The structural design that can be rotated in the same direction as the second rotating wheel 44 is within the scope of the present invention.

In addition, the transmission mechanism 34 has a worm gear 48 that is coupled to the electric actuator 36, and the worm gear 48 is used to transmit the torque output by the electric actuator 36 to the first rotating wheel 42 (eg, 1 and 2). In practice, the electrical actuator 36 can be a motor, such as a DC motor. In addition, to match the tooth profile of the worm gear 48, the first rotating wheel 42 can be a helical gear that is used to engage the worm gear 48 to transmit the torque output by the electrical actuator 36. In addition, the transmission mechanism 34 further includes a pushing member 50, and the pushing member 50 has a transmission gear portion 501. In this embodiment, the transmission gear portion 501 of the pusher 50 is used to engage the second rotating wheel 44, and the second rotating wheel 44 can be a spur gear. In this way, the torque outputted by the electric actuator 36 can be transmitted to the first rotating wheel 42 by the worm gear 48, and then the torsional force is transmitted to the second rotating wheel 44 by the interference mechanism 46, and finally the second rotation is utilized. The wheel 44 transmits the torque to the pusher 50.

In summary, when the electric actuator 36 drives the pusher 50, the first rotating wheel 42 will withstand the torque output from the electric actuating member 36, and the second rotating wheel 44 will withstand the electric lock 30. Torque formed by internal resistance of other internal components (such as pusher 50, etc.). In the normal state, the elastic member 469 can drive the respective fasteners 467 in the radial direction B to respectively engage with the corresponding slots 461 via the openings 465, thereby clamping the first rotating wheel 42 and the second rotating wheel 44. . In this way, the electric actuator 36 can drive the first rotating wheel 42 and the second rotating wheel 44 to rotate in the same direction. Thereby, the torsion generated by the electric actuator 36 can be transmitted to the pushing member 50 via the worm gear 48, the first rotating wheel 42 and the second rotating wheel 44 in sequence, thereby driving the pushing member 50 to rotate.

On the other hand, if the transmission mechanism 34 is faulty, causing the second rotating wheel 44 to be unable to rotate (ie, commonly known as jamming), in this special case, when the electric actuator 36 drives the first rotating wheel 42 to rotate, Due to the smooth engagement pattern between the respective fasteners 467 and the respective card slots 461, the respective fasteners 467 can be easily separated from the corresponding slots 461 as the first rotating wheel 42 rotates. As a result, the first rotating wheel 42 and the second rotating wheel 44 do not interfere, that is, the first rotating wheel 42 can rotate relative to the second rotating wheel 44. As a result, the electric actuator 36 cannot drive the first rotating wheel 42 and the second rotating wheel 44 to rotate in the same direction. By this design, when the second rotating wheel 44 is in a stuck state, the torque generated by the electric actuating member 36 can also be output to the first rotating wheel 42 to be freely idling, and the torque will not be output because the torque cannot be output. The conversion to thermal energy accumulates inside the electrical actuator 36, causing damage to internal components of the electrical actuator 36 due to high heat.

It should be noted that in this embodiment, the electric actuator 36 is engaged with the first rotating wheel 42 by the worm gear 48, and the second rotating wheel 44 is engaged with the transmission gear portion 501 of the pushing member 50, but does not think that limit. For example, in another embodiment, the electric actuator 36 can also be engaged with the second rotating wheel 44 by the worm gear 48, and the first rotating wheel 42 is engaged with the transmission gear portion 501 of the pushing member 50. As described above, the second rotating wheel 44 can be designed as a helical gear, and the first rotating wheel 42 can be designed as a spur gear, so that the gear can meet the transmission requirements. In summary, the electric actuator 36 can be engaged with the first rotating wheel 42 or the second rotating wheel 44 by the worm gear 48. As for the design of the above, it depends on the actual needs.

Please refer to FIG. 6. FIG. 6 is a cross-sectional view showing the components of the first rotating wheel 42', the second rotating wheel 44' and the interference mechanism 46' according to another embodiment of the present invention. As shown in FIGS. 6 and 5, the main difference between the interference mechanism 46' and the interference mechanism 46 described above is that the interference mechanism 46' includes four elastic members 469', four receiving grooves 463', and four. Card firmware 467. In this embodiment, each of the elastic members 469' is a compression spring, and each of the accommodating grooves 463' is an elongated groove, and each of the compression springs is respectively disposed in the elongated groove. Thereby, each of the pressure springs can apply the elastic force of the fastener 467 in the radial direction B, respectively, so that the respective fasteners 467 are pushed outward in the radial direction B. In this way, each of the fasteners 467 is respectively inserted into the corresponding card slot 461 via the opening 465 (as shown in FIG. 6). Thereby, the first rotating wheel 42' and the second rotating wheel 44' can interfere with each other by the respective fasteners 467, so that the torque output by the electric actuator 36 can be applied to the first rotating wheel 42 and the second rotating wheel. 44 passes. It is to be noted that the sixth and fifth figures have the same reference numerals, and have the same structure and function. For the sake of brevity, no further details are provided herein.

Please refer to FIG. 1 and FIG. 7. FIG. 7 is a schematic diagram showing the explosion of some components of the electric lock 30 according to the embodiment of the present invention. As shown in Figures 1 and 7, the transmission mechanism 34 further includes a bottom plate 52. The bottom plate 52 is for attachment to the door panel 32 to secure the transmission mechanism 34 to the door panel 32. Further, the bottom plate 52 has a shaft tube 521, and the pushing member 50 has a hole 503. When the pusher 50 and the bottom plate 52 are mounted, the shaft tube 521 is threaded through the hole 503. As a result, the pushing member 50 can rotate relative to the bottom plate 52. Please refer to FIG. 8 and FIG. 9 . FIG. 8 is a schematic exploded view of the bottom plate 52 and the pushing member 50 according to the embodiment of the present invention. FIG. 9 is an exploded view of the bottom plate 52 and the pushing member 50 in another viewing angle according to an embodiment of the present invention. schematic diagram. As shown in FIG. 8 and FIG. 9, the bottom plate 52 has two first pushed structures 523, and the pushing member 50 further has two second pushed structures 505 and a pushing member 507, and the second pushed structure 505 is It is formed on the pusher portion 507. In addition, the first pushed structure 523 corresponds to the second pushed structure 505, respectively.

It is worth mentioning that the number of the first pushed structure 523 and the second pushed structure 505 may not be limited to those described in this embodiment. For example, the bottom plate 52 can also have a first pushed structure 523, and the pusher 50 can also have a second pushed structure 505 corresponding to the number of the first pushed structures 523. Alternatively, the bottom plate 52 may have three first pushed structures 523, and the pushing members 50 may also have three second pushed structures 505 corresponding to the number of the first pushed structures 523. In other words, as long as the bottom plate 52 has at least one first pushed structure 523 and the pusher 50 has at least one second pushed structure 505, it is within the scope of the present invention. In this embodiment, the first pushed structure 523 and the second pushed structure 505 are each a bevel structure.

Please refer to FIG. 7 , FIG. 10 and FIG. 11 . FIG. 10 is a schematic diagram of components of the transmission mechanism 34 in an initial state according to an embodiment of the present invention. FIG. 11 is a diagram showing the transmission mechanism 34 in an unlatched state according to an embodiment of the present invention. Schematic diagram of the components. As shown in FIG. 7, FIG. 10 and FIG. 11, the transmission mechanism 34 of the electric lock 30 further includes a clutch member 54 and a driving cam 56. The clutch member 54 abuts against the pushing member 50 and is pushed along with the displacement of the pushing member 50, and the driving cam 56 is detachably engaged with the clutch member 54. In addition, the transmission mechanism 34 further includes a latch assembly 58 that is coupled to the drive cam 56. Further, the latch assembly 58 includes a locking bolt 581 and a driving post 583. The locking tongue 581 is used to lock the wall 31, and the driving post 583 is used to connect to the driving cam 56 and the locking tongue 581. In addition, the driving cam 56 is fixed to one end of the driving post 583.

As shown in Figures 1 and 7, the electric lock 30 further includes a handle device 60 that is rotatable relative to a long axis X. Further, the handle device 60 includes a handle portion 601 and a tubular portion 603. The handle portion 601 is exposed to the outside of the bottom plate 52 with respect to the door panel 32 for the user to operate. The tubular portion 603 is coupled to the handle portion 601 and extends through the shaft tube 521 of the bottom plate 52, and the driven post 583 is not interlocked with the tubular portion 603. Further, the clutch member 54 is slidably disposed at one end of the tubular portion 603. Thereby, the clutch member 54 can move relative to the long axis X on the tubular portion 603, and can be disengaged from the driving cam 56 or can be engaged with the driving cam 56. As shown in FIG. 10 and FIG. 11, the torque generated by the electric actuator 36 is sequentially transmitted to the pushing member 50 via the worm gear 48, the first rotating wheel 42, and the second rotating wheel 44, thereby driving the pushing member. When the relatively long axis X is rotated in a first direction D1, the second pushed structure 505 of the pushing member 50 is engaged with the first pushed structure 523 of the bottom plate 52, so that the torque of the pushing member 50 when rotating is It is converted into an axial thrust so that the pusher 50 is slid on the tubular portion 603 and displaced relative to the bottom plate 52 in a first displacement direction X1. As a result, the clutch member 54 can be pushed with the displacement of the pusher member 50 to move from an initial position shown in FIG. 10 to an unlatched position as shown in FIG.

Further, when the clutch member 54 is pushed by the pushing member 50 along the tubular portion 603 to the unlatching position, the clutch member 54 is engaged with the driving cam 56 disposed on the end of the driving post 583. At this time, if the user turns the handle portion 601 of the handle device 60, the torque applied by the user to the handle portion 601 can be transmitted to the clutch member 54 in the direction along the long axis X by the tubular portion 603. As can be seen from the above, when the clutch member 54 is engaged with the unlatching position, the cam 56 is engaged, and the torque can be transmitted from the clutch member 54 along the long axis X to the driving cam 56. Then, the torsion force drives the driving post 583 of the latch assembly 58 to rotate, thereby driving the locking tongue 581 out of the wall surface 31, so that the door piece 32 is correspondingly in the unlatched state.

In addition, the transmission mechanism 34 of the electric lock 30 further includes an elastic member 62 disposed between the clutch member 54 and the driving cam 56. When the clutch member 54 is in the unlatching position as shown in FIG. 11, the clutch member 54 is engageable with the driving cam 56 to compress the elastic member 62. Thereby, the elastic member 62 can store an elastic potential energy due to deformation, and the transmission mechanism 34 can maintain a detachable state for a certain period of time. Then, after the maintenance time of the unlatched state ends, the transmission mechanism 34 returns to the unlatched state, as described below, when the torque generated by the electric actuator 36 is sequentially passed through the worm gear 48, the first rotating wheel. 42 and the second rotating wheel 44 are transmitted to the pushing member 50, thereby driving the pushing member 50 to rotate relative to the long axis X in a second direction D2 opposite to the first direction D1. At this time, the second pushed structure 505 of the pushing member 50 and the first pushed structure 523 of the bottom plate 52 are no longer pushed against each other, so that the clutch member 54 is no longer pushed by the axial thrust of the pushing member 50, but instead The elastic member 62 releases the elastic potential energy to generate an elastic restoring force. In this way, in the above process, the clutch member 54 can be driven by the elastic restoring force of the elastic member 62 to slide on the tubular portion 603, and can be separated from the unlatching position shown in FIG. 11 and opposite to One of the first displacement directions X1, the second displacement direction X2, is displaced relative to the bottom plate 52, and the clutch 54 is disengaged from the driving cam 56 during the displacement until it moves to the initial position as shown in FIG. until.

Further, when the clutch member 54 is pushed by the pushing member 50 along the tubular portion 603 to the initial position, the clutch member 54 is not engaged with the driving cam 56 disposed on the end of the driving post 583. At this time, if the user turns the handle portion 601 of the handle device 60, the torque applied by the user to the handle portion 601 cannot be transmitted to the clutch member 54 in the direction of the long axis X by the tubular portion 603. As can be seen from the above, when the clutch member 54 is engaged with the initial position, the driving cam 56 is not engaged, and the above-mentioned torque cannot be transmitted from the clutch member 54 to the driving cam 56 along the long axis X. Thereby, the handle device 60 cannot transmit the torque to the latch assembly 58 and idle. As a result, the transmission mechanism 34 is in an unlatched state, and the flap 32 is continuously in the latched state.

Please refer to FIG. 12, which is a schematic diagram of some components of the electric lock 30 according to an embodiment of the present invention. As shown in FIG. 12, the electric lock 30 further includes a contact switch 64, and the pusher 50 further has a third pushed structure 66. When the contact switch 64 contacts the third pushed structure 66, the electric actuator 36 is energized. Further, the third pushed structure 66 of the pushing member 50 has a stopping end 68 and an inverting end 70 for controlling the stop and reverse rotation of the electric actuating member 36, respectively. For example, when the electric lock 30 is in the position shown in FIG. 12, the contact switch 64 of the electric lock 30 contacts the third pushed structure 66. At this time, the electric actuator 36 can be controlled to be energized to rotate forward, thereby driving the pusher member 50 to rotate in the first direction D1 until the contact switch 64 contacts the inverting end 70 of the third pushed structure 66. When the contact switch 64 contacts the inverting end 70, the electric actuator 36 stops operating for a set time and then reverses, thereby driving the pushing member 50 to rotate in a second direction D2 opposite to the first direction D1 until the contact switch 64 Contacting the stop end 68 of the third pushed structure 66. At this time, the electric actuator 36 can be controlled to stop operating.

In this way, the electric lock 30 of the present invention can utilize the third pushed structure 66, thereby controlling the electric actuating member 36 to drive the pusher member 50 to rotate in the first direction D1, and using the inverting end 70 to control the electric actuation. The member 36 drives the pushing member 50 to rotate in a second direction D2 opposite to the first direction D1, so that the clutch member 54 can be displaced on the tubular portion 603 along the first displacement direction X1 or the second displacement opposite to the first displacement direction X1. The direction X2 is moved to achieve the purpose of detachably engaging the clutch member 54 to the driving cam 56.

In addition, please refer to FIG. 13, which is a schematic diagram of components of the electric lock 30' according to another embodiment of the present invention. As shown in FIG. 13, the electric lock 30' may further include an unlatching control member 71 coupled to the control unit 40. The control unit 40 can control whether the electric actuating member 36 is energized according to the position of the unlatching control member 71, thereby pushing the clutch member 54 to move to the unlatching position. In addition, when the clutch member 54 moves to the unlatching position according to the above mechanism, the control unit 40 stops the electric actuator 36 from being energized, so that the pushing member 50 continues to push against the clutch member 54, thereby making the clutch member 54 is continuously located at the unlatching position and is engaged with the driving cam 56. In this way, the door piece 32 can be in the unlatched state for a long time.

For example, when the unlatch control member 71 of the electric lock 30' is in the position as shown in FIG. 13, the pusher member 50 and the clutch member 54 are in the initial position as shown in FIG. The signal is input to the control unit 40 by the input unit 38, thereby driving the transmission mechanism 34 to perform subsequent unlatching actions, etc., so that the purpose of unlapping can be achieved. In addition, when the unlatching control member 71 of the electric lock 30' is rotated ninety degrees from the position shown in FIG. 13, the electric actuating member 36 can be controlled to be energized forward to bring the pusher 50 toward the first The direction D1 is rotated, and before the contact switch 64 has touched the reverse end 70 of the third pushed structure 66, the electric actuator 36 is stopped, so that the pusher 50 and the clutch member 54 are stuck in, for example. The unlatching position shown in Fig. 11 means that the clutch member 54 of the electric lock 30' is driven to engage the driving cam 56, so that the user can rotate the handle portion 60 to unlatch without using the input. Unit 38 inputs the signal.

In practice, the electric lock 30' is used in conjunction with the electric lock 30, that is, the electric lock 30' can be installed indoors, and the electric lock 30 can be installed outdoors. Thereby, the user can use the mechanism of the electric lock 30 to unlock the outside to enter the room, and the user can also use the electric lock 30' to control the door piece 32 from the door for a long time in the unlatched state. In this way, when the user needs to repeatedly open the door 32, the user does not need to input the signal every time the door is accessed. With the above design, the electric lock can provide a greater use margin for the user.

Please refer to FIG. 14, which is a schematic view showing the explosion of some components of the electric lock 30 according to the embodiment of the present invention. As shown in Fig. 14, the electric lock 30 further includes a clutch mechanism 72 for transmitting the torque received by the handle device 60 along the long axis X to the latch assembly 58 when the user operates the handle device 60, thereby driving the lock. The latch combination 58 is unlatched. Please refer to FIG. 14 to FIG. 16. FIG. 15 is a schematic view showing the explosion of the components of the clutch mechanism 72 according to the embodiment of the present invention, and FIG. 16 is a schematic view showing the explosion of the components of the clutch mechanism 72 according to another embodiment of the present invention. As shown in Figures 14 through 16, the clutch mechanism 72 includes a key combination 74 that is mounted in the handle portion 601 of the handle assembly 60. In this embodiment, the clutch mechanism 72 further includes a rotating clip 76 having two first pushed structures 761. In addition, the clutch mechanism 72 further includes the clutch member 54 described above, and the clutch member 54 has two second pushed structures 541. In addition, the second pushed structure 541 of the clutch member 54 abuts against the first pushed structure 761 of the rotating clip 76, respectively.

It is worth mentioning that the number of the first pushed structure 761 of the clip 76 and the second pushed structure 541 of the clutch member 54 may not be limited to those described in this embodiment. For example, the clamping member 76 can also have a first pushed structure 761, the clutch member 54 can have a second pushed structure 541 corresponding to the number of the first pushed structure 761, or the engaging member 76 can also There are three first pushed structures 761, and the clutch members 54 can also have three second pushed structures 541 corresponding to the number of first pushed structures 761. In other words, as long as the retaining member 76 has at least one first pushed structure 761 and the clutch member 54 has at least one second pushed structure 541, it is within the scope of the present invention. In this embodiment, the first pushed structure 761 of the retaining member 76 and the second pushed structure 541 of the clutch member 54 are each a beveled structure.

As shown in FIGS. 15 and 16, the key combination 74 includes a lock case 741 and a lock core 743 that is locked in the lock case 741. In addition, the lock housing 741 is used to protect the lock center 743 to avoid damage to the internal components of the lock 743 during use. Further, the lock core 743 has a key drive plate 745. The key drive plate 745 is snapped onto the rotary clamp 76 and used to drive the rotary clamp 76 to rotate, but the rotary clamp 76 is restrained from moving in the direction of the long axis X. In addition, the lock core 743 has a lock groove 747 exposed to one of the lock housings 741 for inserting a key member 78. When the key member 78 is inserted into the lock groove 747, the lock member 78 can unlock the lock case 741 from the lock core 743. Thereby, the user can use the key member 78 to drive the lock core 743 to rotate relative to the long axis X toward a first direction R1, or to drive the lock core 743 relative to the long axis X to be opposite to the first direction R1 and the second direction R2. Turn.

Referring to FIG. 17 and FIG. 18, FIG. 17 is a schematic diagram of components in an initial state of the clutch mechanism 72 according to an embodiment of the present invention. FIG. 18 is a schematic diagram of components of the clutch mechanism 72 in an unlatched state according to an embodiment of the present invention. As shown in FIGS. 17 and 18, when the user drives the lock core 743 to rotate relative to the long axis X toward the first direction R1 by the key member 78, the key combination 74 is driven to rotate toward the first direction R1, thereby driving. The rotating catch member 76 is rotated toward the first direction R1. At this time, the first pushed structure 761 of the rotating clip 76 is engaged with the second pushed structure 541 of the clutch member 54, so that the torque of the rotating clip 76 when rotated is converted into an axial thrust. . Thereby, the rotating member 76 can be pushed against the clutch member 54 so that the clutch member 54 can be displaced relative to the rotating member 76 along the first displacement direction X1 of the long axis X. In this way, the rotating member 76 can push the clutch member 54 in the first displacement direction X1 along the major axis X from an initial position shown in FIG. 17 to an unlatching position as shown in FIG. 18.

Further, when the clutch member 54 is pushed to the unlatching position by the rotating locking member 76 along the first displacement direction X1 of the long axis X, the clutch member 54 is engaged with the driving cam disposed on the end of the driving post 583. 56. At this time, if the user turns the handle portion 601 of the handle device 60, the handle device 60 will rotate the key combination 74, the rotation member 76, and the clutch member 54 together. In this way, the torque applied by the user to the handle portion 601 can be transmitted to the clutch member 54 in the direction of the long axis X. As can be seen from the above, when the clutch member 54 is engaged with the unlatching position, the cam 56 is engaged, and the torque can be transmitted from the clutch member 54 along the long axis X to the driving cam 56. Then, the torsion force drives the driving post 583 of the latch assembly 58 to rotate, thereby driving the locking tongue 581 out of the wall surface 31, so that the door piece 32 is correspondingly in the unlatched state.

In addition, when the clutch member 54 is in the unlatching position as shown in Fig. 18, the clutch member 54 is a compressible elastic member 62. Thereby, the elastic member 62 can store an elastic potential energy due to deformation. Then, when the user drives the lock core 743 to rotate relative to the long axis X toward the second direction R2 by the key member 78, the key combination 74 is driven to rotate toward the second direction R2, thereby driving the rotating card member 76 toward the second direction R2. Turn. At this time, the second pushed structure 541 of the clutch member 54 and the first pushed structure 761 of the rotating clip 76 do not push against each other, so that the clutch member 54 is no longer axially thrusted by the rotating member 76. Pushed, the elastic member 62 releases the elastic potential to produce an elastic restoring force. In this way, in the above process, the clutch member 54 can be driven by the elastic restoring force of the elastic member 62, and the unlatching position as shown in Fig. 18 leaves the driving cam 56, and the opposite direction on the long axis X The second displacement direction X2 in the first displacement direction X1 is displaced relative to the rotating member 76 until it moves to the initial position as shown in FIG.

Further, when the clutch member 54 is pushed to the initial position by the pushing member 50 along the long axis X, the clutch member 54 is not engaged with the driving cam 56 disposed on the end of the driving post 583. At this time, if the user turns the handle portion 601 of the handle device 60, the handle device 60 can only drive the key combination 74 and the rotation of the locking member 76 to rotate, and the clutch member 54 cannot be rotated together. As a result, the torque applied by the user to the handle portion 601 cannot be transmitted to the clutch member 54 in the direction of the long axis X. As can be seen from the above, when the clutch member 54 is engaged with the initial position, the driving cam 56 is not engaged, and the above-mentioned torque cannot be transmitted from the clutch member 54 to the driving cam 56 along the long axis X. Thereby, the handle device 60 cannot transmit the torque to the latch assembly 58 and idle. As a result, the flap 32 is continuously in the latched state.

Referring to FIG. 19, FIG. 19 is a schematic view showing the components of the electric lock 80 according to another embodiment of the present invention. As shown in Fig. 19, the handle assembly 82 of the electric lock 80 includes a housing 84 that is secured to the door panel 32 for mounting the handle assembly 82 to the door panel 32. Further, the handle portion 601 of the handle device 82 is rotatably disposed on the housing 84, and the handle portion 601 is rotatable relative to the long axis X described above. In addition, the handle device 82 further includes a fixing member 86 that is fixed to the housing 84 and is used with the housing 84 to cover the internal components of the electric lock 80, such as an electric actuator, a pushing member, a clutch member, and the like. The internal components of the electric lock 80 described above are prevented from being damaged by an external force.

Referring to FIGS. 20 to 22, FIG. 20 is a schematic view showing the internal components of the handle device 82 according to another embodiment of the present invention, and FIG. 21 is an internal component of the handle device 82 in another state according to another embodiment of the present invention. Fig. 22 is a partial cross-sectional view showing the handle device 82 shown in Fig. 20. As shown in Figs. 20 to 22, the handle device 82 further includes a commutator segment 88. The commutator segment 88 is coupled to the handle portion 601 by the tubular portion 603 described above, and the tubular portion 603 is configured to transmit the torsion force received by the handle portion 601 to the commutator segment 88. Thereby, the commutator segment 88 can be driven by the handle portion 601 and rotated with the handle portion 601. In addition, a first groove 881 and a second groove 883 are formed on the commutator segment 88, and the first groove 881 has a first side S1 and a second side S2, and the second groove 883 has a first Three sides S3 and a fourth side S4. In this embodiment, the commutator segments 88 are substantially circular structures, and the first grooves 881 and the second grooves 883 are respectively arcuate grooves and formed on the circumference of the circular structure.

In addition to this, as shown in Fig. 22, the handle device 82 further includes a reset member 90. The reset member 90 is disposed between the housing 84 and the commutator segment 88 and is configured to provide a torque to reset the commutator segment 88, that is, when the external force is applied to the handle device 82 to rotate the handle device 82. The reset member 90 stores an elastic potential energy due to deformation. When no external force is applied to the handle device 82, the reset member 90 releases its elastic potential energy. Further, the handle device 82 further includes a stopper piece 92 which is disposed on one side of the commutator segment 88 so as to be movable in a direction parallel to the long axis X. The stop tab 92 has a stop structure 921 that can protrude into the first recess 881 of the commutator segment 88 or into the second recess 883. As shown in Figs. 19 to 22, a through hole 861 is formed in the fixing member 86, and the stopper piece 92 has a protrusion 923 at a position corresponding to the through hole 861. In addition, the handle device 82 further includes an elastic member 94 that elastically abuts against the stop piece 92 and the housing 84 to bias the stop piece 92. Thereby, the elastic member 94 can support the stopper piece 92 so that the protrusion 923 of the stopper piece 92 can pass through the through hole 861 of the fixing piece 86, and the protrusion 923 of the stopper piece 92 can be exposed and fixed. Pier 861 on piece 86.

Further, when the stopper piece 92 is biased by the elastic member 94, the stopper piece 92 is movable toward the commutator piece 88 in a direction parallel to the long axis X. Thereby, the stop structure 921 of the stop piece 92 can protrude in the first groove 881 of the commutator segment 88 or the second groove 883, so that the handle portion 601 is correspondingly in a first rotation state or A second direction of rotation. In practice, the elastic member 94 is preferably a compression spring, but is not limited thereto. For example, the elastic member 94 may also be a resilient support structure such as a rubber gasket or the like. In other words, any structural design that can elastically abut and support the stopper piece 92 is within the scope of protection of the present invention.

When the stop structure 921 of the stop piece 92 protrudes from the first recess 881 of the commutator segment 88, at this time, if no external force is applied to the handle device 82, the reset member 90 releases its elastic potential energy. The commutator segment 88 is driven to rotate the commutator segment 88 along a first turn W1 as shown in FIG. 20 until the first side S1 of the first recess 881 of the commutator segment 88 abuts the stop tab 92 Stop structure 921. At this time, the stopper structure 921 of the stopper piece 92 stops the first side S1 of the first groove 881 so that the handle portion 601 cannot continue to rotate along the first direction W1. Thereby, the handle portion 601 can be correspondingly located at a first starting position as shown in FIG.

At this time, if the user turns the handle portion 601 of the handle device 82, the handle portion 601 is rotated toward the second steering W2 opposite to the first steering W1, thereby driving the commutator segment 88 along the second steering W2 as shown in FIG. The first starting position shown is rotated until the second side S2 of the first recess 881 of the commutator segment 88 abuts the stop structure 921 of the stop tab 92. At this time, the stopper structure 921 of the stopper piece 92 stops the second side S2 of the first groove 881 so that the handle portion 601 cannot continue to rotate in the second direction of the W2. Thereby, the handle portion 601 can be correspondingly located at one of the first end positions as shown in FIG. Further, if the user releases the handle portion 601 when the handle portion 601 is in the first end position, or the user releases the handle portion 601 when the handle portion 601 is located at the other non-first starting position, the reset member 90 can be This torque is provided to the commutator segments 88, whereby the commutator segments 88 are driven and the handle portion 601 is reset to the first home position. In this way, the handle portion 601 of the handle device 82 can achieve the effect of automatically resetting to the first starting position.

In summary, when the stop structure 921 of the stop piece 92 protrudes from the first groove 881 of the commutator segment 88, the rotation of the handle portion 601 is the first side S1 and the second side of the first groove 881. The side S2 is limited, and can only be rotated between the first starting position as shown in Fig. 20 and the first ending position as shown in Fig. 21. In this way, the handle portion 601 of the handle device 82 can be in the first state of rotation. In this embodiment, the first state of rotation can be designed to be in a right-handed state, that is, the first state of rotation is designed for a user with a dominant hand for the right hand.

Please refer to FIG. 20 to FIG. 24, FIG. 23 is a schematic diagram of internal components of the handle device 82 in another state according to another embodiment of the present invention, and FIG. 24 is another embodiment of the handle device 82 according to another embodiment of the present invention. Schematic diagram of the internal components of the state. When the user wants to change the state of the knob of the handle portion 601 of the handle device 82, a pressing rod 96 is first inserted into the through hole 861 of the fixing member 86 (as shown in Fig. 19). At this time, the protrusion 923 of the stopper piece 92 is pushed by the pressing rod 96, thereby driving the stopper piece 92 to move toward the handle portion 601. Thereby, the stop structure 921 of the stop piece 92 can be disengaged from the first recess 881 of the commutator segment 88 (as shown in Fig. 22). At this time, the handle portion 601 can be freely rotated without being restricted by the stopper structure 921 of the stopper piece 92, so that the user can change its state of rotation. In addition, the stopper piece 92 simultaneously compresses the elastic member 94 in the above process to store the elastic member 94 with an elastic potential energy. Thereby, the handle portion 601 of the handle device 82 and the commutator segment 88 can be rotated along the first steering position W1 from the first starting position shown in FIG.

At this time, the user can rotate the handle portion 601 of the handle device 82, thereby driving the commutator segment 88 to rotate along the first steering W1 until the third side S3 of the second groove 883 of the commutator segment 88 is turned to the 23rd. In one of the second starting positions shown, the plunger 96 is removed from the perforations 861 on the fixture 86. At this time, the elastic member 94 releases the elastic potential energy, thereby generating an elastic restoring force. Thereby, the elastic member 94 can drive the stopper piece 92 to be reset, that is, the stopper piece 92 can be driven by the elastic member 94 to move to the second groove 883 in a direction parallel to the long axis X of the handle portion 601. It is worth mentioning that the fixing member 86 can be used to stop the stopper piece 92 during the resetting of the above-mentioned stopper piece 92, thereby preventing the self-stopping piece 92 from being detached from the second groove 883.

When the stop piece 92 is located in the second recess 883, the stop structure 921 of the stop piece 92 stops the third side S3 of the second recess 883 (as shown in Fig. 23). As a result, the handle portion 601 cannot be rotated along the second steering W2. Thereby, the handle portion 601 can be correspondingly located at the second starting position as shown in FIG. At this time, if the user rotates the handle portion 601 of the handle device 82, the handle portion 601 is rotated toward the first steering W1, thereby driving the commutator segment 88 to be along the first turn W1 as shown in the second start of FIG. The position is rotated until the fourth side S4 of the second recess 883 of the commutator segment 88 abuts against the stop structure 921 of the stop piece 92. At this time, the stopper structure 921 of the stopper piece 92 stops the fourth side S4 of the second groove 883 so that the handle portion 601 cannot continue to rotate in the direction of the first steering W1. Thereby, the handle portion 601 can be correspondingly located at a second end position as shown in Fig. 24. Further, if the user releases the handle portion 601 when the handle portion 601 is in the second end position, or the user releases the handle portion 601 when the handle portion 601 is located at the other non-second starting position, the reset member 90 This torque can be provided to the deflector 88 to drive the commutator segments 88 and the handle portion 601 to be reset to the second home position. In this way, the handle portion 601 of the handle device 82 can achieve the effect of automatically resetting to the second starting position.

In summary, when the stop structure 921 of the stop piece 92 protrudes in the second groove 883 of the commutator segment 88, the rotation of the handle portion 601 is the third side S3 and the fourth of the second groove 883. The side S4 is limited to rotate only between the second starting position as shown in Fig. 23 and the second ending position as shown in Fig. 24. As a result, the handle portion 601 of the handle device 82 can be in a second state of rotation. In this embodiment, the second state of rotation can be designed to be in a left-handed state, that is, the second state of rotation is designed for a user with a left handed hand.

When the user wants to change the handle portion 601 from the second rotation state to the first rotation state, the pressure bar 96 is first inserted into the through hole 861 of the fixing member 86. At this time, the protrusion 923 of the stop piece 92 is pushed by the pressing rod 96 to drive the stopper piece 92 out of the second groove 883 of the commutator piece 88, and at the same time compress the elastic piece 94 to store the elastic piece 94 with an elastic position. can. Thereby, the handle portion 601 of the handle device 82 and the commutator segment 88 can be rotated along the second starting position W2 from the second starting position shown in FIG. Next, when the user rotates the handle portion 601 of the handle device 82, the commutator segment 88 is driven to rotate along the second turn W2 until the first side S1 of the first groove 881 of the commutator segment 88 is turned to FIG. When the first starting position is shown, the plunger 96 is removed from the perforations 861 on the fixture 86. At this time, the elastic member 94 releases the elastic potential energy, thereby generating the elastic restoring force. Thereby, the elastic member 94 can drive the stopper piece 92 to be reset, that is, the stopper piece 92 can be driven by the elastic member 94 to move to the first groove 881 in a direction parallel to the long axis X of the handle portion 601. It is worth mentioning that the fixing member 86 can be used to stop the stopper piece 92 during the resetting of the above-mentioned stopper piece 92, thereby preventing the self-stopping piece 92 from being disengaged from the first groove 881.

In this embodiment, the reset member 90 is preferably a torsion spring. Referring to FIG. 25 to FIG. 27, FIG. 25 is a schematic diagram of components of the handle portion 601 at the first starting position and another viewing angle according to another embodiment of the present invention, and FIG. 26 is a handle of another embodiment of the present invention. The component 601 is located in the second starting position in another view. FIG. 27 is a schematic diagram of the component of the handle portion 601 in an initial position according to another embodiment of the present invention. It should be noted that when the handle portion 601 is located at the initial position, the torsion spring is in a free position, that is, the torsion spring does not have torsional deformation. In practice, the initial position is substantially perpendicular to the first starting position and the second starting position. In summary, the torsion spring has a torsional deformation relative to the initial position regardless of whether the handle portion 601 is in the first rotation state or the second rotation state. Therefore, the torsion spring stores an elastic potential energy whether the handle portion 601 is in the first rotation state or the second rotation state, so the first initial state of the handle portion 601 from the first rotation state The torsion spring releases the elastic potential energy when the position or the first end position is released, or when the handle portion 601 is released from the second initial position or the second end position of the second rotation state. An elastic restoring force is generated to drive the handle portion 601 to move toward the initial position, that is, the torsion spring drives the handle portion 601 to be reset to the first initial position or the second initial position.

Compared with the prior art, the key combination of the present invention is coupled to the rotating card member, so that when the user drives the key combination with the key member, the key combination can directly drive the rotating card member. At this time, since the first pushed structure on the rotating engaging member abuts against the second pushed structure on the clutch member, the engaging member is rotated by the cooperation of the first pushed structure and the second pushed structure. The clutch member can be pushed, so that the clutch member can be displaced relative to the rotating card member to be engaged with the latch module. In this way, the structural design of the present invention is simplified, and only the rotating card member can be used to convert the rotating action of the key combination into the clutch moving member of the clutch member, which not only saves material cost of the object but also simplifies the assembly process, so The production does not require more manpower for assembly, thereby saving the production cost of the electric lock, thereby increasing the price competitive advantage of the electric lock in the market.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
