Detailed Description
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
The invention will be described in detail below with reference to the drawings in connection with embodiments.
The present embodiment relates to a multifunctional electronic control lock, as shown in fig. 1 and 2, in which parts that do not affect understanding of the embodiment are hidden for clarity of illustration. The multifunctional electric control lock comprises a lock body 1, a lock tongue 2 arranged in the lock body 1, a traction unit 3 fixedly connected to one end of the lock tongue 2, and an electric driving mechanism 4 and a mechanical driving mechanism 5 which are in transmission connection with the traction unit 3. The multifunctional electric control lock further comprises a guide unit fixedly connected to one end of the lock tongue 2, a lock tongue clamping block 24 which is slidably arranged on the guide unit and provided with a first limiting part 241, an elastic piece 25 which is sleeved on the guide unit and is respectively fixedly connected to the lock tongue 2 and the lock tongue clamping block 24 at two ends, and a first clamping mechanism 6 which is matched with the first limiting part 241 and can limit the movement of the lock tongue clamping block 24. In addition to the above structure, in this embodiment, the lock cylinder 51 of the mechanical driving mechanism 5 is further provided with a lock cylinder block 7, the lock cylinder block 7 is provided with a second limiting portion 71, and the lock body 1 is provided with a second locking mechanism 8 that cooperates with the second limiting portion 71 to limit rotation of the lock cylinder block 7.
In this embodiment, as shown in fig. 1, the mechanism of the lock tongue 2 is provided with two symmetrically arranged inclined planes 21 on one end, i.e. the working end, which can be inserted into an external mechanism to complete locking. Therefore, when the multifunctional electric control lock is installed on the door body, any side of the lock tongue 2 faces the inside of the door due to the symmetrical structure of the working end of the lock tongue, and inconvenience caused by incorrect installation direction during installation is avoided. Meanwhile, in order to facilitate the operation of the bolt 2 during unlocking and locking, two guide pulleys 22 with rotation directions tangential to the movement direction of the bolt 2 are arranged on the two inclined planes 21 at intervals. The structure of the traction unit 3 of the present embodiment for driving the lock tongue 2 to extend or retract into the lock body 1 is shown in fig. 1, which is fixed at one end of the lock tongue 2 located in the lock body 1, and has a bar-like shape, and a first latch 31 is provided at one side thereof.
The mechanical driving mechanism 5 and the electric driving mechanism 4 can drive the traction unit 3 to drive the lock tongue 2 to extend out of or retract into the lock body 1. The structure of the electric drive mechanism 4 is shown in fig. 1, and comprises an electric transmission unit which is in transmission with the traction unit 3, and a power device which is fixed on the lock body 1 and is in driving connection with the electric transmission unit. In this embodiment, the power device is a first motor 41, and the electric driving mechanism 4 is a first gear 42 meshed with the first latch 31. Therefore, the motor rotates to drive the first gear 42 to rotate, and then drive the traction unit 3 to move, so as to complete the locking or unlocking actions of the locking bolt 2 extending out of or retracting into the lock body 1.
As shown in fig. 1 and 4, the mechanical driving mechanism 5 includes a lock cylinder 51 fixed to the lock body 1, and a mechanical transmission unit fixed to the lock cylinder 51, which in this embodiment is a second gear 52 engaged with the first latch 31. When the lock cylinder 51 is opened or closed, the second gear 52 is driven to rotate, so as to drive the traction unit 3 to move, and the locking bolt 2 can also extend out of or retract into the lock body 1, namely, the locking or unlocking action is completed. Of course, the connection between the electric drive mechanism 4 and the mechanical drive mechanism 5 and the traction unit 3 is not limited to the rack and pinion 623, and may be a slider-crank mechanism, that is, a mechanism in which the traction unit 3 is linearly moved by rotation of the key cylinder 51 or the first motor 41.
In this embodiment, the guide unit is shown in fig. 2, and is a cylindrical guide rod 23 positioned in the lock body 1 and fixed to one end of the locking bolt 2.
The latch block 24 slidably disposed on the guide rod 23 has a bar-shaped block shape as shown in fig. 3, and has a central hole 2401 formed at the center thereof, which is sleeved on the guide rod 23, and a guide bar 242 disposed above the central hole, wherein the guide bar 242 is inserted into the guide groove 32 of the traction unit 3 to prevent the latch block 24 from rotating. An elastic piece 25 sleeved on the guide rod 23 is arranged between the lock tongue clamping block 24 and the lock tongue 2 end, and two ends of the elastic piece 25 are respectively fixedly connected to the lock tongue clamping block 24 and the lock tongue 2. Meanwhile, a first limiting portion 241 is further disposed on the latch bolt clamping block 24. Under normal working conditions, the elastic piece 25 is in an initial state, and the lock tongue 2 and the lock tongue clamping block 24 can synchronously move. Under the power-off condition, the first limiting portion 241 can cooperate with the first locking mechanism 6 to limit the movement of the latch block 24, and the latch 2 can still be driven to move by the mechanical driving mechanism 5 due to the compression or recovery of the elastic member 25. In this embodiment, the elastic member 25 is a spring. Obviously, the guiding unit may also be a strip-shaped plate, and correspondingly, the central hole 2401 on the latch block 24 is replaced by a form of arranging the guiding unit.
As shown in fig. 3, the first locking mechanism 6 includes a first actuating unit 61 that cooperates with the first limiting portion 241 to limit movement of the latch bolt latch 24, and a first power unit 62 that is in driving connection with the first actuating unit 61 and can cooperate with or disengage the first actuating unit 61 from the first limiting portion 241.
Specifically, in this embodiment, the first limiting portion 241 is a limiting hole disposed on one side of the latch bolt clamping block 24. The first actuating unit 61 is a latch pin slidably disposed in the lock body 1. The clamping block pin is arranged on the sliding sleeve fixedly arranged on the lock body 1 in a penetrating way and can slide in the round sleeve, and the sliding sleeve is not shown in the figure because the understanding is not affected. The latch pin may be inserted into the limiting hole by the first power unit 62 to limit the movement of the latch 24.
The first power unit 62 is constructed as shown in fig. 3 and 4, and includes a second motor 621 fixed to the lock body 1, a screw rod 622 drivingly connected to the second motor 621, and a rack 623 reciprocally movable in rotation with the screw rod 622, and a cam 624 rotatably provided to the lock body 1, the cam 624 being rotated by a shaft body fitted around one side thereof and fixedly connected to the lock body 1, which is not shown in the drawings because it does not affect understanding. The cam 624 has a variable diameter end that slidably engages the latch pin and an equal diameter end formed with a second latch that engages the rack 623.
The engagement of the rack 623 with the screw 622 is illustrated in fig. 3 and 4, and a mounting portion is provided on the side of the rack 623 facing away from the cam 624 to extend toward the screw 622, and a screw hole is provided in the mounting portion. The threaded bore is in threaded engagement with the screw 622. Whereby the motor rotates the screw 622, which moves the rack 623 and rotates the cam 624. By controlling the direction of rotation of the motor, reciprocating rotation of cam 624 may be achieved. When the fixture block pin slides to the high point of the cam 624, the fixture block pin is inserted into the limit hole; when the latch slides to the lower point of the cam 624, the latch is released from the limiting hole under the action of gravity. Obviously, the first limiting portion 241 may be a limiting groove, and the corresponding first actuating unit 61 may be a clamping block that can be inserted into the limiting groove, so as to meet the blocking fit between the limiting groove and the first actuating unit 61. The structure for realizing the engagement or disengagement of the first action unit 61 and the first limiting portion 241 may be a slider-crank mechanism, and only the first action unit 61 needs to be reciprocated.
The lock cylinder 51 of the mechanical driving mechanism 5 includes a housing, a first core 511 corresponding to a key, a second core 512 corresponding to a knob, and a shift fork 513 driven by the first core 511 and the second core 512, and the above-mentioned second gear 52 is fixed to the shift fork 513. The first core 511 may be turned by a key adapted to the key cylinder 51 to rotate the fork 513. The second core 512 may be rotated by the knob to rotate the fork 513.
The key cylinder block 7 is provided to restrict rotation of the first core 511 and the second core 512 at some timing. In this embodiment, the rotation of the first core 511 is limited as an example. The lock cylinder block 7 is shown in the figure, and is a concentric ring fixedly connected to the first lock cylinder 51. The lock cylinder clamping block 7 is provided with a second limiting unit, and the second limiting unit can be matched with the second clamping mechanism 8 to limit the rotation of the lock cylinder clamping block 7, namely, the rotation of the first inner core 511.
In this embodiment, the second action unit 81 in the second locking mechanism 8 is specifically configured to cooperate with the second limiting unit to limit the rotation of the lock cylinder fixture block 7. In addition to the second actuating unit 81, the second locking mechanism 8 further comprises a second power unit 82 in driving connection with the second actuating unit 81.
More specifically, in this embodiment, the second limiting unit is an arc groove provided on the circumference of the lock cylinder fixture block 7, and the arc groove is arranged concentrically with the lock cylinder fixture block 7. The second actuating unit 81 is an actuating lever slidably disposed in the lock body 1. The actuating lever is slidable within a sleeve, which is not shown in the figures, by being threaded through a circular sleeve fixedly connected to the lock body 1, without affecting the understanding.
The action rod can be inserted into the circular arc groove under the action of the second power unit 82, and one side of the circular arc groove is blocked by the action rod and cannot rotate in the unlocking direction, namely, the key cannot drive the first inner core 511 to rotate in the unlocking direction, so that unlocking cannot be completed. When mechanical unlocking is required, such as power-off, the action rod is separated from the circular arc groove under the action of gravity, and at this time, the first inner core 511 can be driven by the key to complete unlocking. Because the mechanism of the first inner core 511 for driving the shifting fork 513 is a splayed mechanism, that is, the shifting fork 513 is driven to rotate after the first inner core 511 needs to rotate a certain angle, the shifting fork 513 can still be driven by the electric driving mechanism 4 to rotate towards the unlocking direction, and unlocking is completed. The inside splayed connection mechanism of the first core 511 and the fork 513 is a prior art, and will not be described herein.
The second power unit 82 is configured as shown in fig. 4, in which a rack bar 623 is omitted, the second power unit 82 includes a second motor 621 and a screw 622 in the first power unit 62, and further, the second power unit 82 includes a transmission plate 821 having the same mounting portion as the rack bar 623, the transmission plate 821 is slidably engaged with the actuating lever, and a protrusion 8211 is provided on a side of the transmission plate 821 facing the actuating lever, the protrusion 8211 is specifically a step having inclined surfaces on both sides, and when the actuating lever slides onto the step, the protrusion is inserted into the circular arc groove due to being supported. When the action bar slides away from the step, the action bar is separated from the circular arc groove due to the action of gravity.
The second core 512 driven by the knob is limited in the same manner as the first core 511 described above, and the limitation of the first core 511 and the second core 512 can be simultaneously accomplished by one transmission plate 821 by changing the position of the circular arc groove on the second core 512 and the position of the step on the transmission plate 821 corresponding to the second core 512. By providing the step position, the second operation unit 81 and the second stopper 71 are disengaged when the first operation unit 61 and the first stopper 241 are engaged, and the second operation unit 81 and the second stopper 71 are engaged when the first operation unit 61 and the first stopper 241 are disengaged. Of course, the second locking mechanism 8 can be provided with a motor and a screw independently, but has the disadvantages of higher cost, large occupied space and adverse arrangement.
The control unit is configured to complete the cooperation of the first action unit 61 and the first limiting portion 241 and the detachment of the second action unit 81 and the second limiting portion 71 after power failure, and in this embodiment, the control unit specifically includes a detection module for detecting an external power signal, a control module for controlling the electric driving mechanism 4 and the first power unit 62 to act, and a standby power module electrically connected to the control module, the electric driving mechanism 4, and the first power unit 62. In this embodiment, the CPU completes the functions of the detection module and the control module, and the capacitor completes the functions of the standby power module. Of course, the standby power module may be an additional energy storage power source. But compared with an additional energy storage power supply, the capacitor has lower cost under the condition of completing the same function.
Through the above arrangement, under the normal energizing condition, the first limiting unit is disengaged from the first limiting portion 241, the second limiting unit is engaged with the second limiting portion 71, and the lock cylinder 51 cannot be opened by a key or a knob. Due to the connection of the elastic member 25, the latch block 24 moves synchronously with the latch 2. The electric driving mechanism 4 drives the traction unit 3 to enable the lock tongue 2 to extend out of or retract into the lock body 1, so as to complete locking or unlocking.
When the detection module detects that the power supply signal is terminated, the standby power supply module supplies power, and the control module controls the first motor 41 to rotate first to drive the latch bolt clamping block 24 to move so that the first limiting portion 241 is located at a position corresponding to the first action unit 61. Then, the control module controls the second motor 621 to rotate, so that the first moving element is inserted into the first limiting portion 241, and the second moving unit 81 is separated from the second limiting portion 71. The bolt 2 is now in a position extending out of the lock body 1. In the case of an unrecoverable power supply, the bolt 2 can compress the elastic member 25 to retract into the lock body 1 when turned by a key knob fitted to the lock cylinder 51. After unlocking, the restoring force of the elastic piece 25 pushes the end of the lock tongue 2 to extend out of the lock body 1, so that automatic locking is finished, and locking is finished without a key or a knob.
After the power is restored, the control module controls the second motor 621 to rotate, the first action unit 61 is separated from the first limiting part 241 under the action of gravity, and the second action unit 81 is matched with the second limiting part 71, so that the lock is restored to a state that the lock can only be unlocked by the electric driving mechanism 4.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
