Description

Technical Field

[0001] The invention belongs to the technical field of intelligent door locks, and in particular relates to an automatic lock body with a handle unlocking device. Background Art

[0002] At present, the fully automatic lock bodies on the market all realize the locking or unlocking state of the door lock by electronically controlling the extension or retraction of the lock tongue. During use, when the electronic control system fails to work, the electronic control system cannot realize the extension or retraction of the lock tongue. At this time, if the lock tongue is directly retracted to open the door by mechanical external force, for example, the lock tongue is directly retracted by turning the door handle to open the door, the movement of the lock tongue will drive the motor to rotate. Since the movement of the lock tongue driven by the motor is realized by a set of high-speed gear reduction transmission mechanism, the movement of the lock tongue drives the motor to rotate, which constitutes 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 handle is laborious to unlock or even cannot be unlocked. Summary of the invention

[0003] In order to overcome the defects of the above-mentioned prior art, the purpose of the present invention is to provide an automatic lock body with a handle unlocking device and a clutch device, which can quickly and smoothly retract the lock tongue using the door handle when the lock tongue is in any state, thereby improving the convenience and safety of using the fully automatic lock body.

[0004] The invention discloses an automatic lock body with a handle unlocking clutch device, comprising a lock body shell and a lock tongue assembly, and also comprising a motor assembly for driving the lock tongue assembly to move. The lock body shell is also provided with a handle connecting assembly, a driving assembly, a gear assembly and a clutch device. The motor assembly is connected to the gear assembly and can drive the gear assembly to rotate, and 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 switch the synchronous rotation state of the motor assembly and the gear assembly to connection or separation. The handle connecting assembly is connected to the handle on the door panel. When the handle drives the handle connecting assembly to rotate, the clutch device is first opened, and then the driving assembly is driven to rotate, thereby driving the lock tongue assembly to move.

[0005] Furthermore, the handle connecting assembly includes a main tongue shift block, and also includes a main tongue drive plate and a commutator plate which are mounted on the main tongue shift block and rotate synchronously with the main tongue shift block. The commutator plate is provided with a flange for pushing the clutch device, and a column for driving the main tongue drive plate; the main tongue drive plate is provided with a notch which cooperates with the column, and an extension portion for driving the drive assembly to rotate, thereby realizing synchronous rotation of the commutator plate and the main tongue drive plate.

[0006] Furthermore, the handle connecting assembly also includes a main tongue paddle and a reversing screw. The main tongue paddle is mounted on the main tongue paddle block and rotates synchronously with the main tongue paddle block. The main tongue paddle block and the main tongue paddle can also be an integral part, that is, a part. The reversing screw detachably connects the main tongue paddle and the reversing piece to achieve synchronous rotation of the main tongue paddle and the reversing piece.

[0007] Furthermore, the main tongue block and the main tongue paddle are each one on the upper and lower parts, the main tongue paddle is sleeved on the main tongue paddle block and rotates synchronously with the main tongue paddle block, and a gasket is provided between the two main tongue paddle blocks, the gasket allows the square rod connecting the handle and the handle connecting assembly to allow only one of the main tongue paddle blocks to rotate alone; and a reversing screw is provided on one of the main tongue paddles and is detachably connected to the reversing segment, so that one of the main tongue paddles can rotate synchronously with the reversing segment.

[0009] Furthermore, a return spring is provided between the clutch movable block and the motor assembly. When the clutch paddle moves the clutch movable block to separate the clutch movable block from the clutch gear, the clutch movable block compresses the return spring at the same time. When the force of the clutch paddle on the clutch movable block is withdrawn, the return spring pushes the clutch movable block to engage with the clutch gear.

[0010] Furthermore, the front end of the manual clutch bracket is rotatably connected to the lock body shell, and a pushing column is provided in the middle.

[0019] The automatic lock body with a handle unlocking and clutching device of the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0020] like Figures 1 to 6 As shown, in a preferred embodiment, an automatic lock body with a handle unlocking and clutch device of the present invention comprises a lock body shell 1 and a lock tongue assembly 2, and also comprises a motor assembly 3 for driving the lock tongue assembly 2 to move. A handle connecting assembly 4, a driving assembly 5, a gear assembly 6 and a clutch device 7 are also arranged in 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, and 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 can switch the synchronous rotation state of the motor assembly 3 and the gear assembly 6 to connection or separation. Since the motor assembly will limit the rotation of the gear assembly, only when the motor assembly and the gear assembly 6 are separated can the mechanical unlocking be easily realized; the handle connecting assembly 4 is connected to the handle outside the lock body. When the handle drives the handle connecting assembly 4 to rotate, the clutch device 7 is first opened, and then the lock tongue assembly 2 is driven to move by the driving assembly 5, so that the mechanical handle can be switched on and off smoothly and quickly at any time.

[0021] In this embodiment, the handle connecting assembly 4 includes a main tongue shift block 41, and also includes a main tongue driving plate 43 and a commutator plate 44 which are sleeved on the main tongue shift block 41 and rotate synchronously with the main tongue shift block 41. The commutator plate 44 is provided with a flange 441 for pushing the clutch device 7, and a column 442 for driving the main tongue driving plate 43; the main tongue driving plate 43 is provided with a notch 431 which cooperates with the column 442, and an extension portion 432 for driving the driving assembly 5 to rotate, so as to realize the synchronous rotation of the commutator plate 44 and the main tongue driving plate 43. When the handle connecting assembly 4 rotates, it first drives the main tongue shift block 41 to rotate, and the main tongue shift block 41 then drives the commutator plate 44 to rotate. When the commutator plate 44 rotates, it drives the ejection clutch device 7 through the flange 441, so that the motor assembly 3 will not rotate with the gear assembly 6, and at the same time drives the main tongue drive plate 43 to rotate through the column 442, and the extension part 432 on the main tongue drive plate 43 drives the drive assembly 5 to rotate, and the rotation of the drive assembly 5 drives the lock tongue to extend and retract, thereby realizing the door lock switch.

[0022] The handle connection assembly 4 also includes a main tongue paddle 42 and a reversing screw 45. The main tongue paddle 42 is sleeved on the main tongue paddle block 41 and rotates synchronously with the main tongue paddle block 41. The main tongue paddle block 41 and the main tongue paddle 42 can also be designed as one part. The reversing screw 45 detachably connects the main tongue paddle 42 with the reversing piece 44 to achieve synchronous rotation of the main tongue paddle 42 and the reversing piece 44. At this time, the main tongue paddle 42 and the main tongue paddle block 41 have matching edges, that is, they can rotate synchronously through the action of at least one edge, and the main tongue drive piece 43 and the reversing piece 44 are sleeved in the main tongue paddle block 41. The cavity is circular, and the rotation of the main tongue paddle block 41 will not directly drive the main tongue drive piece 43 and the reversing piece 44 to rotate, but first drives the main tongue paddle 42, and then drives the reversing piece 44 to rotate through the reversing screw 45, and finally the column 442 on the reversing piece 44 drives the main tongue drive piece 43 to rotate.

[0023] More optimally, in order to better use the door lock and realize the separate control of different combinations of left-opening and right-opening or inner-opening and outer-opening, the main tongue block 41 and the main tongue paddle 42 are each one in the front and back, the main tongue paddle 42 is sleeved on the main tongue paddle 41 and rotates synchronously with the main tongue paddle 41, and a gasket 46 is provided between the two main tongue paddle blocks 41 to ensure that the square rod connecting the handle and the handle assembly and one of the main tongue paddles are quickly linked, so that the front and rear main tongue paddle blocks 41 can rotate separately. At the same time, by setting a reversing screw 45 on one of the main tongue paddles 42, the reversing screw 45 detachably connects one of the main tongue paddles 42 with the reversing piece 44, so that one of the main tongue paddles 42 and the reversing piece 44 can rotate synchronously, so that one lock body can adapt to the door opening conditions of different combinations of left, right and inner and outer door opening, meet the installation requirements of different door opening methods, and realize the versatility of the product. .

[0024] More optimally, 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 through the rack 221.

[0025] To ensure the stability of the clutch device 7, the clutch device 7 includes a clutch paddle 73, a clutch gear 71, a clutch movable block 72 and a manual clutch bracket 74; the clutch gear 71 is sleeved on the rotating shaft of the motor assembly 3, the clutch gear 71 rotates relative to the rotating shaft and is connected to the gear assembly 6; the clutch movable block 72 is sleeved on the rotating shaft of the motor assembly 3 and rotates synchronously with the rotating shaft, the manual clutch bracket 74 can drive the clutch paddle 73 to move, and the clutch paddle 73 can drive the clutch movable block 72 to separate from the clutch gear 71. The front end of the manual clutch bracket 74 is rotatably connected to the lock body shell 1 as a rotating point, and the rotating connection can be a rotating column, a pin, a bearing or other rotatable connection methods; a pushing column 741 is provided in the middle, and when the commutator 44 rotates, its flange 441 contacts the pushing column 741 to push the manual clutch bracket 74; the rear end of the manual clutch bracket 74 can contact the clutch paddle 73 and push the clutch paddle 73 to move, thereby realizing the ejection of the clutch device 7; and a reset spring 75 is provided between the clutch movable block 72 and the motor assembly 3. When the force of the clutch paddle 73 acting on the clutch movable block 72 is cancelled, the reset spring 75 pushes the clutch movable block 72 to engage with the clutch gear 71. In addition, the clutch paddle 73 is provided with a bayonet 731 near the clutch bracket 74, and the lower end of the clutch bracket 74 is clamped into the bayonet 731; the clutch paddle 73 is provided with a blocking piece 732, and the blocking piece 732 is clamped on the clutch movable block 72. The clutch movable block 72 can be provided with a bayonet, a groove, a protrusion and other structures that cooperate with the blocking piece 732, and the technical effect of using the blocking piece 732 to push the clutch movable block 72 to move can be achieved. When the door handle is rotated, the flange 441 on the reversing piece 44 in the handle connection assembly 4 pushes the push column 741. Due to the directional S-shaped structure of the manual clutch bracket 74, its rear end is a free end, and the free end can drive the clutch paddle 73 to move, and the blocking piece 732 on the clutch paddle 73 pushes the clutch movable block 72 away from the clutch gear 71, so that the clutch device 7 is opened, and the motor assembly 3 no longer affects the rotation of the gears in the gear assembly 6, so that the handle can be easily unlocked. When the handle is released, under the action of the return spring 75, the clutch movable block 72 is again clamped into the clutch gear 71 to achieve linkage.

[0026] 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 72 is a corresponding half-tooth shape, that is, the clutch movable block 72 can be driven to rotate through the plane on the rotating shaft, and the middle hole of the clutch gear 71 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.
