Description
Technical Field
[0001] The invention relates to the technical field of door locks, and in particular to a fully automatic lock body. Background Art
[0002] At present, motion locks are gradually emerging in the smart lock market. One of the methods is: when the correct password or fingerprint and other information is entered, the lock tongue can simulate the action of opening the door with a key through the group drive of the motor located on the panel to achieve the effect of automatic unlocking. However, this automatic unlocking method has major disadvantages. The first generation of products uses high-power output motors and gear groups to adapt to different door installation environments and deformations. In this case, a higher voltage power supply (mostly lithium battery packs) must be used, which has high power consumption and uneven quality of lithium batteries. Because the motor group is located in the panel, customers can use different traditional mechanical lock bodies to match them. The lock bodies used are of different standards, the quality of internal parts is uneven, and the output of large torque often causes damage to the internal parts of the lock body. Because the motor group is relatively large and the motor mechanisms on the market are relatively uniform, the rear panel design is monotonous, thick, and square, which is not conducive to a better product appearance design. The second generation products are semi-automatic lock bodies with built-in motor groups developed independently by some manufacturers with independent R&D capabilities. Due to limitations such as structural design and standard lock body size, the products use less torque and can only drive the extension and retraction of the main lock body that is not oppressed. The cross tongue that ensures that the main lock tongue is not oppressed and has the function of locking the door needs to be unlocked by the handle, so it can only be called a semi-automatic lock body.
[0003] A conventional lock tongue consists of a buckling surface (which is perpendicular to the lock body finish) and an inclined surface. When the door is closed, the inclined surface and the door frame form a component force perpendicular to the lock body finish. Under the action of the spring, the lock tongue retracts into the lock body. When it reaches the strike plate hole, it rebounds and extends again, achieving the effect of locking the door. When opening the door, the lock tongue needs to be retracted through a rotating mechanism.
[0004] Therefore, we propose a fully automatic lock body to overcome the above-mentioned defects. Summary of the invention

When applied to a large-size lock body, two motors can be used for simultaneous output. Two Hall detectors are arranged in the lock body to detect the steady state after the main tongue moves. When a locking command is received, the detection switch is first scanned to determine the position of the main tongue, and then the motor is driven to work. If the main tongue is blocked from extending due to deformation of the door frame or the like, the position detection switch and the current detection circuit are combined to detect the main tongue position. The circuit can be known, and the next step instruction is issued to enter the high-power working state (if a single motor is used, the output voltage is increased; if a dual motor is used, one more motor is started to cooperate). The motor first reverses to drive the reduction gear group to reverse, and the main tongue that has only been partially extended is first recovered. Then the circuit enables the other side circuit to store electricity in the capacitor. When the electricity is reached, the motor (or dual motors) is released to ensure that the main tongue can be extended normally; the motor transmits power to the reduction gear group. The reduction gear group is connected with the logic gear group, so that the main tongue toggle piece rotates to toggle the main tongue out. In this process, the lock core rotating block is connected to the linkage paddle and rotates synchronously. If it is necessary to enable external driving force to open the lock body, the rotation of this component can drive the output gear and the linkage paddle to rotate, thereby achieving the effect of mechanical unlocking.

The movable limiting groove 4012, when the door is closed, the rolling tongue return spring 406 drives the rolling tongue locking plate 402 to be clamped in the limiting groove 4012; the rolling tongue assembly 40 also includes a linkage rod 407; the linkage rod 407 is provided with a rolling tongue telescopic guide groove 409; the rolling tongue telescopic guide groove 409 is slidably provided with a sliding guide block 404; the rolling tongue linkage plate 403 is fixedly connected to the sliding guide block 404; a tension spring 408 is provided between one end of the linkage rod 407 and the inner wall of the lock shell 10; the other end of the linkage rod 407 is provided with a linkage block 4071 and extends to one side of the logic gear set 70. The rolling tongue 401 not only has a telescopic function, but also has a rolling function, which greatly facilitates people's use and solves the defect that the conventional lock tongue needs to be retracted by a rotating mechanism when opening the door.
[0040] like Figure 3As shown, as a preferred solution, the detection assembly 50 includes a triangular tongue 501 and a triangular tongue return spring 502 ; the triangular tongue 501 is driven and controlled by the triangular tongue return spring 502 .
[0041] like Figure 2 As shown, as a preferred solution, the driving device 60 includes a motor box 601 equipped with at least one motor and a reduction gear set 602 equipped with a reduction gear; the reduction gear set 602 is meshed and connected with the logic gear set 70.
[0042] like Figure 4 As shown, in this embodiment, the logic gear group 70 includes a lock core rotating block 701; the outer wall of the lock core rotating block 701 is sleeved with an input gear 704 and an output gear 705; the input gear and the output gear are respectively meshed and connected with the reduction gear group 602 and the main tongue shifting member 303; the outer wall of the lock core rotating block 701 is also provided with a logic gear position detection block 702 and a linkage paddle 703; the logic gear position detection block 702 is movably connected with the lock core rotating block 701; the linkage paddle 703 drives and controls the movement of the linkage block 4071.
[0043] like Figure 3 As shown, in this embodiment, a triangular tongue position detector 801, a Hall detector 802 and an infrared detector 803 are provided on the programmable control circuit board 80; the triangular tongue position detector 801 is used to obtain the position information of the triangular tongue 501; the Hall detector 802 is used to obtain the position information of the main tongue 301 when it is in a stable state; the infrared detector 803 is used to obtain the position information of the logic gear position detection block 702.
[0044] Working principle: Figure 2 , 7As shown in Figure 8, the present invention adopts a self-locking rolling tongue design. The rolling tongue 401 not only has a telescopic function, but also has a rolling function. When the door is closed, the a surface is squeezed by the door frame, so that the b surface is perpendicular to the lock body side plate 20, and the a surface becomes an inclined surface. At the same time, the rolling tongue locking plate 402 enters the preset limiting groove 4012 of the rolling tongue 401 under the action of the rolling tongue return spring 406, so that the rolling tongue 401 cannot continue to roll. At this time, the rolling tongue 401 can only maintain this angle and compress inward along the rolling tongue telescopic guide groove 409 on the linkage rod 407 until it reaches the buckle plate hole and then resets and extends out under the action of the rolling tongue return spring 406. However, at this time, the rolling tongue 401 still However, it cannot roll over in the locked straight state, and the door lock is locked; when the door is opened, the mechanism acts on the rolling tongue locking plate 402, causing it to move backward along the rolling tongue telescopic guide groove 409 until it disengages from the preset limit groove 4012 of the rolling tongue 401. At this time, the rolling tongue 401 unlocks the rolling function, and the door is pushed out at this time. Under the squeezing of the door frame, the b surface rotates from perpendicular to the lock body side plate 20 to an inclined surface, and the a surface becomes perpendicular to the lock body side plate 20. Under the action of the external force of pushing the door and the b surface, a component force is generated to retract the rolling tongue 401, and the rolling tongue 401 retracts into the lock body and releases the buckling effect on the door frame, and then disengages from the door frame, the rolling tongue 401 rebounds and extends out, and the door opening action is completed.
[0045] like Figure 3 As shown, the present invention can achieve this by changing the output power of the motor through controlling the input voltage of the motor. Due to the size limitation of the motor, the maximum safe output power of the selected motor is also greatly limited. When applied to a large-sized lock body, two motors can be used for simultaneous output. Two Hall detectors 802 are arranged in the lock body for detecting the movement of the main tongue 301, one for detecting the stable position of the main tongue 301 when it is retracted, and the other for detecting the stable position of the main tongue 301 when it is extended. When a locking command is received, the detection switch is first scanned to determine the position of the main tongue 301, and then the motor is driven to work. At this time, the motor is in a normal low-power working state, and its main function is to reduce power consumption and extend battery life. If the extension of the main tongue 301 is blocked due to deformation of the door frame or other reasons, it can be known by combining the position detection switch and the current detection circuit, and a next step instruction is issued to enter a high-power working state (if a single motor is used, the output voltage is increased, and if a dual motor is used, one more motor is started to cooperate). The motor first reverses to drive the reduction gear set 602 to reverse, and the main tongue 301 that is only partially extended is first retracted, and then the circuit enables the other side circuit to store electricity in the capacitor. When the power is reached, the motor (or dual motor) is released. This high-power working cycle is up to three times, and an alarm is issued to inform the user. The first stage of the reduction gear set 602 is equipped with a worm gear motor to improve the output ratio.
[0046] like Figure 4 and 5As shown, the motor transmits power to the reduction gear set 602, which is connected to the input gear 704. The output gear 705 is provided with an idle stroke space of a certain angle, so that the motor does not directly carry a load when starting, but is connected to the load after an idle stroke. When the idle stroke is exhausted, the output gear 705 will be driven to rotate. At this time, the output gear 705 is connected to the main tongue toggle member 303, so that the main tongue toggle member 303 rotates to toggle the main tongue 301 to extend. At the same time, the input gear 704 and the linkage paddle 703 also have an idle stroke of a certain angle. When the idle stroke is exhausted, the linkage block 4071 is also driven to move to unlock the locking of the rolling tongue 401. In this process, the lock core rotating block 701 is connected to the linkage paddle 703 and rotates synchronously. If an external driving force is required to open the lock body, the rotation of this component can drive the rotation of the output gear 705 and the linkage paddle 703 to achieve the effect of mechanical unlocking.

A fully automatic lock body according to claim 4, characterized in that: The programmable control circuit board is provided with a triangular tongue position detector, a Hall detector and an infrared detector; the triangular tongue position detector is used to obtain the position information of the triangular tongue; the Hall detector is used to obtain the position information of the main tongue when it is in a stable state; the infrared detector is used to obtain the position information of the logic gear position detection block; Two Hall sensors are arranged in the lock body for detecting the movement of the main tongue, one for detecting the stable position of the main tongue when it is retracted, and the other for detecting the stable position of the main tongue when it is extended; when a locking instruction is received, the detection switch is first scanned to determine the position of the main tongue, and then the motor is driven to work, at which time the motor is in a normal low-power working state; If the main tongue is blocked from extending due to deformation of the door frame at this time, it is known by combining the position detection switch and the current detection circuit, and the next step instruction is issued to enter the high-power working state, the single motor increases the output voltage or the dual motor starts one more motor to cooperate; the motor first reverses to drive the reduction gear set to reverse, and the main tongue that is only partially extended is first recovered, and then the circuit activates the other side circuit to store electricity in the capacitor, and releases the single motor or the dual motor when the power is reached. This high-power working cycle is not more than three times, and an alarm is issued to inform the user. The first stage of the reduction gear set is matched with a worm gear motor to improve the output ratio.
