Description

Technical Field

[0001] The invention belongs to the technical field of intelligent door locks, and in particular relates to an automatic lock body which can be installed with a mechanical lock core and is provided with a clutch device. Background Art

[0002] At present, the fully automatic lock bodies on the market are all controlled by the electronic system to control the motor assembly to rotate forward or reverse to push out or retract the lock tongue to achieve the locking or unlocking state of the door lock. During use, when the electronic control system fails to work, the motor assembly cannot rotate to achieve the lock tongue to push out or retract. At this time, if the lock tongue is directly retracted to open the door by mechanical external force, for example, the mechanical lock core is directly rotated with a key to retract the lock tongue to open the door, the movement of the lock tongue will drive the motor assembly to rotate. Since the movement of the motor to drive the movement of the lock tongue is achieved by a set of high-speed gear reduction transmission mechanism, and at this time, the movement of the lock tongue drives the motor to rotate to form a high-speed gear speed increase transmission mechanism, which will cause the transmission mechanism to be particularly laborious or even self-locking, resulting in the situation that the key is laborious to unlock or even cannot unlock. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic lock body which can be installed with a mechanical lock core and has a clutch device. The lock core is directly installed and used in the fully automatic lock body, which is convenient for unlocking and improves the safety of the lock body.

[0004] An automatic lock body capable of installing a mechanical lock core and having a clutch device comprises a lock body shell and a lock tongue assembly, and also comprises a motor assembly for driving the lock tongue assembly to move. A lock core, a drive assembly, a gear assembly and a clutch device are also arranged in the lock body shell. A mounting hole for installing the lock core is arranged on the lock body shell. The motor assembly is connected to the gear assembly and can drive the gear assembly to rotate. The gear assembly is connected to the lock tongue assembly and can drive the lock tongue assembly to move. The clutch device is arranged between the motor assembly and the gear assembly, and can adjust the synchronous rotation state of the motor assembly and the gear assembly to connection or separation. When the lock core rotates, the clutch device can be driven first to switch the synchronous rotation state of the motor assembly and the gear assembly to separation, and then the drive assembly can be driven to rotate, thereby driving the lock tongue assembly to move.

[0005] Furthermore, the lock tongue assembly includes a lock tongue and a drive block fixed on the lock tongue, a rack is provided on one side of the drive block, the rack matches the gear in the gear assembly, and the motor assembly drives the gear in the gear assembly to rotate through the rotating shaft, thereby driving the lock tongue to move.

[0006] Furthermore, the clutch device includes a clutch shift block, a clutch paddle, a clutch gear, a clutch movable block and a reset spring; the clutch gear is sleeved on the rotating shaft of the motor assembly, and can rotate relative to the rotating shaft, and can drive the gear inside the gear assembly to rotate; the clutch movable block is sleeved on the rotating shaft of the motor assembly and rotates synchronously with the rotating shaft, and engages with the clutch gear to drive the clutch gear to rotate; the clutch shift block can drive the clutch paddle to move, and the clutch paddle can drive the clutch movable block to separate from the clutch gear; the reset spring is arranged between the clutch movable block and the motor assembly, and can always push the clutch movable block toward the clutch gear.

[0007] Furthermore, one end of the clutch block is rotatably connected to the lock body shell, and the other end is a free end, which contacts the clutch paddle; the middle part of the clutch block is close to the lock core, and when the lock core rotates, it can push the clutch block to rotate, and its free end can push the clutch paddle.

[0008] Furthermore, the clutch block is arc-shaped on one side close to the lock core, and the arc can be divided into a distal end, a middle section of the arc, and a proximal end. During the process of the lock core rotating and passing through the clutch block, the lock core first passes through the proximal end of the clutch block, then passes through the middle section of the arc of the clutch block, and finally passes through the distal end of the clutch block; during the rotation of the lock core, the displacement distance of the free end of the clutch block remains unchanged.

[0009] The automatic lock body of the present invention can be installed with a mechanical lock core and has a clutch device. The design is scientific and reasonable. The lock core and the clutch device are directly installed in the full-automatic lock body. The key can be easily used to unlock the lock when the lock tongue is in any state.

[0020] The automatic lock body of the present invention which can be installed with a mechanical lock cylinder and has a clutch device will be further described in detail below in conjunction with specific embodiments and drawings.

[0021] like Figures 1 to 10 As shown, in a preferred embodiment, an automatic lock body of the present invention that can be installed with a mechanical lock core and has a clutch device, includes a lock body shell 1 and a lock tongue assembly 2, and also includes a motor assembly 3 for driving the lock tongue assembly 2 to move. A lock core 4, a drive assembly 5, a gear assembly 6 and a clutch device 7 are also provided in the lock body shell 1. A mounting hole 101 for installing the lock core 4 is provided on the lock body shell 1. The motor assembly 3 is connected to the gear assembly 6 and can drive the gear assembly 6 to rotate. The gear assembly 6 is connected to the lock tongue assembly 2 and can drive the lock tongue assembly 2 to move; the clutch device 7 is arranged between the motor assembly 3 and the gear assembly 6, and the synchronous rotation state of the motor assembly 3 and the gear assembly 6 can be adjusted to connection and separation; when the lock core 4 rotates, the clutch device 7 can be driven first to switch the synchronous rotation state of the motor assembly 3 and the gear assembly 6 to separation, and then drive the drive assembly 5 to rotate to drive the lock tongue assembly 2 to move.

[0022] In order to make the lock core 4 fixed and stable and not easy to loosen, it also includes a bolt 8 and a fixing plate 9 arranged beside the lock core 4 for fixing the bolt 8. The lock core 4 is also provided with a through hole 41; the lock body shell 1 includes an upper bottom shell 11, a lower bottom shell 12 and a side plate 13. The fixing plate 9 is arranged between the upper bottom shell 11 and the lower bottom shell 12. The bolt 8 passes through the side plate 13 and is inserted into the lock body, and then passes through the through hole 41 on the lock core 4, and is finally fixed with the fixing plate 9; the upper bottom shell 11 and the lower bottom shell 12 are both provided with mounting holes 101 to facilitate the installation of the lock core (4). Since the bolt 8 is inserted from the side plate 13, it is difficult to remove the lock core 4 without completely destroying the lock body or opening the lock, thereby improving the safety of the lock body.

[0023] To further ensure the stability of the lock core 4, the fixing plate 9 is U-shaped, and the lock core 4 is arranged in the U-shaped recess of the fixing plate 9, so that the lock core 4 has support on both sides and better stability.

[0024] To ensure smooth unlocking, the lock tongue assembly 2 includes a lock tongue 21 and a drive block 22 fixed on the lock tongue 21. A rack 221 is provided on one side of the drive block 22. The rack 221 matches the gear assembly 6. The motor assembly 3 drives the gear assembly 6 to rotate through the rotating shaft, thereby driving the lock tongue 21 to move.

[0025] To ensure that the clutch device 7 is stable and effective, the clutch device 7 includes a clutch shift block 71, a clutch shift piece 72, a clutch gear 73, a clutch movable block 74 and a return spring 75; the clutch gear 73 is sleeved on the rotating shaft of the motor assembly 3, and can rotate relative to the rotating shaft, and can drive the internal gear of the gear assembly 6 to rotate; the clutch movable block 74 is sleeved on the rotating shaft of the motor assembly 3 and rotates synchronously with the rotating shaft, and meshes with the clutch gear 73 to drive the clutch gear 73 to rotate; the clutch shift block 71 can drive the clutch shift piece 72 to move, and the clutch shift piece 72 can drive the clutch movable block 74 to separate from the clutch gear 73; the return spring 75 is arranged between the clutch movable block 74 and the motor assembly 3, and can always push the clutch movable block 74 toward the clutch gear 73, so that when the clutch shift block 71 does not generate thrust, it is ensured that the clutch movable block 74 and the clutch gear 73 produce a linkage effect. In this embodiment, one side of the rotating shaft of the motor assembly 3 is a plane, and correspondingly, the middle hole of the clutch movable block 74 is a corresponding half-tooth shape, that is, the clutch movable block 74 can be driven to rotate through the plane on the rotating shaft, and the middle hole of the clutch gear 73 sleeved on the rotating shaft is a circle and does not rotate with the rotating shaft. Similarly, the rotating shaft can also be of other edge shapes, and the same technical effect can also be achieved.

[0026] As a further optimization of this embodiment, one end of the clutch block 71 is rotatably connected to the lock body shell 1, and the other end is a free end 711, and the free end 711 is in contact with the clutch paddle 72; the middle of the clutch block 71 is close to the lock cylinder 4, and when the lock cylinder 4 rotates, it can push the clutch block 71, and its free end 711 can push the clutch paddle 72. Further, it also includes a guide column 76, and the clutch block 71 is provided with an elliptical notch 712 sleeved on the guide column 76, and the lock tongue assembly 2 is provided with a guide groove 222, and the guide groove 222 is also sleeved on the guide column 76. In this way, the guide column 76 can limit the accuracy of the moving direction of the lock tongue, and can also limit the moving range of the clutch block 71, ensuring stable operation of the structure and smooth unlocking.

[0027] As a further optimization of this embodiment, the clutch block 71 is arc-shaped on one side close to the lock cylinder 4, and the arc can be divided into a distal end 713, an arc-shaped middle section 714 and a proximal end 715; specifically, the lock cylinder 4 used in this embodiment is a common mechanical lock cylinder, and its main rotating component is the lock cylinder block 42 on the lock cylinder 4. When the key is used to unlock the lock, the key rotates and drives the lock cylinder block 42 to rotate, so that when the lock cylinder 4 rotates and passes through the clutch block 71, when the key rotates and drives the lock cylinder block 42 to rotate, the lock cylinder 4 rotates and passes through the clutch block 71. When the lock cylinder block 42 rotates counterclockwise to unlock, it first passes through the proximal end 715 of the clutch block 71, then passes through the middle arc section 714 of the clutch block 71, and finally passes through the distal end 713 of the clutch block 71; conversely, when the key is turned to drive the lock cylinder 4 to rotate counterclockwise to lock, the lock cylinder block 42 first passes through the distal end 713 of the clutch block 71, then passes through the middle arc section 714 of the clutch block 71, and finally passes through the proximal end 715 of the clutch block; when the lock cylinder block 42 rotates, it contacts the clutch block 71. In the process of 71 passing the proximal end 715 or the distal end 713 to the starting point of the arc-shaped middle section 714, the lock core shift block 42 drives the clutch shift block 71 to rotate. When the clutch shift block 71 rotates, the free end 711 drives the clutch shift piece 72 to move. The clutch shift piece 72 moves to drive the clutch movable block 74 out of the meshing state. At the same time, the clutch movable block 74 compresses the reset spring 75 to store energy. When the lock core shift block 42 contacts the arc-shaped middle section 714 and rotates, the displacement distance of the free end 711 of the clutch shift block 71 remains unchanged. , that is, the clutch movable block 74 and the clutch gear 73 are always in a separated state; at the same time, the lock core shift block 42 contacts the arc-shaped middle section 714 during rotation, driving the drive assembly 5 to move, and the drive assembly 5 moves, driving the lock tongue assembly 2 to move, thereby unlocking or locking; when the rotating lock core shift block 42 passes through the distal end or proximal end from the arc-shaped area in the middle of the contact clutch shift block 71 to the process of disengaging from the contact with the clutch shift block 71, the reset spring 75 pushes the clutch movable block 74 to move and engage with the clutch gear 73.

[0028] The driving assembly 5 is rotatably connected to the guide column 76, and the driving assembly 5 is provided with a driving column 51 and a flange 52. The driving block 22 is provided with a driving groove 223 corresponding to the driving column 51. When the lock cylinder 4 rotates, the driving assembly 5 is driven to rotate by toggling the flange 52, and the driving assembly 5 drives the lock tongue assembly 2 to move through the driving column 51. In addition, the forward and reverse rotation of the lock cylinder 4 can drive the above structure to move and rotate accordingly, so as to realize the extension and retraction of the lock tongue 21, that is, the forward and reverse rotation of the lock cylinder 4 can directly realize the unlocking and locking, which is convenient to operate and improves safety.
