Description

Technical Field

[0001] The present invention relates to the technical field of lock bodies, and in particular to a smart lock body with an anti-pry function and a door equipped with the lock body. Background Art

[0002] Electronic locks need to be powered by a power cord for control. Therefore, when destroying an electronic lock, one only needs to remove the front panel of the lock body outside the door to expose part of the motor, and then short-circuit the power cord of the motor (i.e., the power supply cord). This will cause the motor to drive the main lock tongue to retract into the lock body. At this point, the door is already open, so the existing electronic locks have poor anti-pry function. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a smart lock body with an anti-pry function, which cannot be unlocked even if the electrodes of the motor are short-circuited when prying, thereby further improving the anti-pry capability of the lock body.

[0004] A second object of the present invention is to provide a door.

[0005] One of the purposes of the present invention is achieved by the following technical solution:

[0006] Smart lock body with anti-pry function, including:

[0007] case;

[0008] A lock tongue assembly installed in the housing, the lock tongue assembly comprising a moving part and a lock tongue installed on the moving part, the lock tongue being movably plugged into the housing;

[0009] The execution drive mechanism includes a motor, a locking mechanism drivingly connected to the motor, and a lock core peach pivotally connected to the housing; the lock core peach is used to move the moving member to allow the lock tongue to extend and retract relative to the housing; the locking mechanism is used to lock the lock core peach to prevent the lock core peach from rotating;

[0010] A control system installed inside the housing, the control system being electrically connected to the motor, and the motor being started or stopped by the control system;

[0011] An inductive drive system is installed inside or outside the shell, and the inductive drive system signal is connected to the control system.

[0012] Furthermore, the control system is a single chip microcomputer, a single board computer or an embedded system.

[0013] Furthermore, the inductive drive system is one of a mechanical contact switch, a wireless proximity inductive switch, an ultrasonic distance sensor, a photoelectric sensor, and a magnetic control sensor.

[0014] Furthermore, the induction drive system is a micro switch.

[0015] Furthermore, the locking mechanism includes a slider, one of the slider and the lock core nuts has a slot, and the other has a block, and the block is suitable for engaging the slot to lock the lock core nuts.

[0016] Furthermore, the lock core shifter is also provided with a lever, and the movable part is provided with a plurality of linearly arranged teeth with grooves between adjacent teeth. When the lock core shifter rotates, the lever is adapted to engage with the groove to push the teeth so that the lock tongue can be extended and retracted relative to the housing.

[0017] Furthermore, the slider is movably connected to the rotating shaft of the motor; the locking mechanism also includes a transmission spring, which is arranged in the slider and movably connected to the rotating shaft of the motor; the rotating shaft of the motor has a pressure rod which protrudes along its own radial direction and passes through the transmission spring, and the pressure rod is used to drive the transmission spring to move in a straight line so that the slider moves along the axial direction of the motor.

[0018] Furthermore, the slider includes a first block and a second block connected to and synchronized with the first block, the clamping block is arranged in the first block, and the transmission spring is arranged in the second block; one of the first block and the second block is provided with a limit groove, and the other is provided with a limit block, and the limit block is embedded in the limit groove.

[0019] Furthermore, the shell is provided with a guide plate, which is parallel to the movement direction of the first block and abuts against the first block.

[0020] The second object of the present invention is achieved by adopting the following technical solution:

[0021] The door comprises the smart lock body with anti-pry function.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In order to lock the lock tongue when prying, so as to prevent the lock tongue from shrinking into the shell. When the induction drive system triggers the control system, the control system then controls the motor to start, and the motor then drives the locking mechanism to prevent the lock core peach from rotating. Therefore, even if there is a hole on the front panel for the rod to insert into the straight groove (i.e., the inner hole) of the lock core peach, the lock core peach cannot be rotated, thereby ensuring that the lock tongue is extended outside the shell, and the anti-pry effect is better.

[0024] 2. In addition, since the control system is arranged inside the shell, the electrical connection between the control system and the motor is in a concealed state (that is, it is stored inside the shell), so the wires (control lines) cannot be pulled out or damaged through the holes in the front panel, that is, the electrical connection between the control system and the motor cannot be damaged, so that the control system always controls the start and stop of the motor. Even if the power cord of the motor is taken out or short-circuited, the motor will not start, further enhancing the anti-pry effect.

[0025] 3. Most importantly, the locking mechanism locks the lock core and the lock disk, and protects the electrical connection between the control system and the motor from being damaged, thereby ensuring that the lock tongue is not moved by the lock core and the door remains locked, thereby ensuring a high level of anti-pry capability.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "horizontal", "vertical", "top", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internally connected between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] It should be explained first that in the prior art, many general electronic locks have a real lock core or a fake lock core in the lock body, and the keyhole of the real lock core requires an adapted key to rotate. The fake lock core is driven by a chip and a motor (that is, the chip controls the motor, and the motor controls the lock tongue to extend and retract). The lock core nut 33 of the fake lock core is generally provided with a straight groove 333, that is, an inner hole, and any rod can twist the straight groove 333 (that is, the inner hole). When a fake lock core is used, that is, when the motor drives the lock tongue to open or lock the door, it is easy to be pried open. The root cause is that as long as the front panel is removed, the straight groove 333 (that is, the inner hole) is exposed to the external environment (there is a hole on the housing 1 facing the straight groove 333), resulting in that at this time, as long as a rod passes through the hole on the housing 1, the straight groove 333 (that is, the inner hole) can be turned to rotate, thereby unlocking and opening the door; that is, the overall anti-pry effect is poor.

[0033] In order to solve the problem that the door can be opened by short-circuiting the motor 31, the present invention sets the control system 4 inside the housing 1. At this time, the connecting wires between the control system 4 and the motor 31 are located inside the housing 1, which can maintain the electrical connection between the control system 4 and the motor 31 (and not be maliciously cut off, because if the control system 4 is installed on the front panel or the rear panel of the lock body, after the front panel is violently removed, the electrical connection between the control system 4 and the motor 31 can be cut off by pulling the wires. At this time, the motor 31 can be rotated as long as the motor 31 is short-circuited). Therefore, installing the control system 4 inside the housing 1 can prevent the electrical connection between the control system 4 and the motor 31 from being maliciously damaged. At this time, even if the electrodes of the motor 31 are short-circuited, the motor 31 will not bypass the control system 4 and start automatically.

[0034] Specifically, Figure 1-Figure 2 The figure shows a preferred embodiment of a smart lock body with an anti-pry function of the present invention, comprising: a shell 1, a lock tongue assembly 2 installed in the shell 1, an execution drive mechanism 3, a control system 4 installed inside the shell 1 (to ensure that the electrical connection between the control system 4 and the motor 31 is not maliciously cut off), and an induction drive system installed inside or outside the shell 1 (not shown in the figure).

[0035] The lock tongue assembly 2 includes a moving part 21 (the moving part 21 is preferably a thin plate part, that is, it can also be a part of other structures), a lock tongue 22 installed (fixedly installed or elastically installed) on the moving part 21, and the lock tongue 22 is movably inserted into the housing 1 to achieve a locked door state or an unlocked door state.

[0036] The actuator drive mechanism 3 includes a motor 31, a locking mechanism 32 drivingly connected to the motor 31, and a lock core shifter 33 pivotally connected to the housing 1 (i.e., a lock core shifter 33 of a fake lock core, the lock core shifter 33 having a straight groove 333); the lock core shifter 33 is used to move the moving part 21 to allow the lock tongue 22 to extend and retract relative to the housing 1; the locking mechanism 32 is used to lock the lock core shifter 33 to prevent the lock core shifter 33 from rotating.

[0037] The control system 4 is electrically connected to the motor 31 , and the motor 31 is started or stopped by the control system 4 .

[0038] The induction drive system signal is connected to the control system 4.

[0039] When the inductive drive system detects prying (such as the lock body or door panel being pried), the inductive drive system inputs a signal to the control system 4, so that the control system 4 controls the motor 31 to start and the locking mechanism 32 locks the lock core 33. When the lock core 33 is locked and cannot rotate, the lock core 33 will not be able to move the moving part 21 back into the housing 1, that is, the lock tongue 22 remains extended outside the housing 1 to ensure the door is locked.

[0040] More importantly, it is necessary to reiterate that in order to lock the lock tongue 22 when prying occurs, so as to prevent the lock tongue 22 from shrinking into the housing 1. When the induction drive system triggers the control system 4, the control system 4 then controls the motor 31 to start, and the motor 31 then drives the locking mechanism 32 to prevent the lock cylinder nut 33 from rotating. Therefore, even if there is a hole in the front panel for the rod to be inserted into the straight groove 333 (i.e., the inner hole) of the lock cylinder nut 33, the lock cylinder nut 33 cannot be rotated, thereby ensuring that the lock tongue 22 is extended outside the housing 1, and the anti-pry effect is better. In addition, since the control system 4 is arranged inside the shell 1, the electrical connection between the control system 4 and the motor 31 is in a hidden state (that is, the control line is stored inside the shell 1), and thus the wires (control lines) cannot be pulled out or damaged through the holes in the front panel, that is, the electrical connection between the control system 4 and the motor 31 cannot be damaged, so that the control system 4 always controls the start and stop of the motor 31, and even if the power cord of the motor 31 is taken out or short-circuited, the motor 31 will not start, further enhancing the anti-pry effect.

[0041] Most importantly, the locking mechanism 32 locks the lock core peach 33, and the electrical connection between the protection control system 4 and the motor 31 is not damaged, thereby ensuring that the lock tongue 22 is not moved by the lock core peach 33 and remains in the locked state, thereby ensuring a high anti-pry capability. In other words, the premise of unlocking is that the moving part 21 of the lock tongue 22 is moved by the lock core peach 33, and the premise of the lock core peach 33 rotating is that the motor 31 drives the locking mechanism 32 to release the lock of the lock core peach 33, and the motor 31 is controlled by the control system 4; and the electrical connection relationship between the motor 31 and the control system 4 is hidden and protected inside the housing 1. Therefore, even if the front panel is removed according to the existing violent prying method to expose the straight groove 333 (i.e., the inner hole) of the lock core peach 33, it cannot be unlocked, which greatly improves the anti-pry capability of the lock body. In addition, it should be mentioned that in the present invention, the function of the motor 31 is to drive the locking mechanism 32 to lock the lock core peach 33 to prevent the lock core peach 33 from being rotated when pried. Compared with the motor driving the lock tongue 22 to extend and retract in the prior art, the present invention also substantially changes the concept of how the lock body is pried-proof. The difference is: in essence, even if the control system 4 is set in the shell 1 in the prior art, when the front panel of the lock body is removed, the straight groove 333 (i.e., the inner hole) of the lock core peach 33 is already exposed to the external environment, that is, only any rod needs to be inserted into the straight groove 333 to open the door, that is, the function of the motor in the prior art is only to provide a drive for the lock tongue 22 to automatically lock or unlock; the anti-prying ability is poor.

[0042] Preferably, the control system 4 is a single chip microcomputer, a single board computer, an embedded system or other conventional control systems 4 .

[0043] Preferably, the inductive drive system is one of a mechanical contact switch, a wireless proximity inductive switch, an ultrasonic distance sensor, a photoelectric sensor, and a magnetic control sensor.

[0044] Preferably, the inductive drive system is a micro switch.

[0045] Preferably, the locking mechanism 32 includes a slider 321, one of which has a slot 331 and the other has a block 32111, and the block 32111 is suitable for engaging the slot 331 to lock the lock core 33. This arrangement can make the locking method convenient, facilitate the drive of the motor 31, and be easy to manufacture. Obviously, in addition to this arrangement, it can also be through direct abutment limiting, that is, the block 32111 interferes with the rotation of the lock core 33 (that is, the slot 331 is not required); it can also be that a gear is fixed on the lock core 33, that is, the motor 31 drives other rods or racks to lock it.

[0046] Preferably, the lock core peach 33 is also provided with a lever 332, and the moving part 21 is provided with a plurality of linearly arranged teeth 211, and a groove 212 is provided between adjacent teeth 211. When the lock core peach 33 rotates, the lever 332 is adapted to engage with the groove 212 to push the teeth 211, so that the lock tongue 22 is extended and retracted relative to the housing 1. In this way, the moving part 21 is directly moved by the lever 332 of the lock core peach 33, simplifying the structure of the lock body. It should be supplemented here that the lock core peach 33 can move the moving part 21 either directly by the lever 332 or indirectly by adding conventional transmission parts such as gears and racks. For example, a gear and rack set can be added, the gear is fixed to the lock core peach 33, and the rack is fixedly connected to the moving part 21.

[0047] Preferably, the slider 321 is movably connected to the rotating shaft of the motor 31; the locking mechanism 32 also includes a transmission spring 322, which is arranged in the slider 321 and movably connected to the rotating shaft of the motor 31; the rotating shaft of the motor 31 has a pressure rod 311 protruding along its own radial direction and passing through the transmission spring 322, and the pressure rod 311 is used to drive the transmission spring 322 to move linearly (that is, the pressure rod 311 rotates to force the transmission spring 322 to move linearly), so that the slider 321 moves along the axial direction of the motor 31. That is, when the transmission spring 322 moves, it can move by elastic force. This arrangement can make the movement process of the slider 321 smoother, with low noise and small impact force, which is conducive to protecting the lock body. Obviously, in addition to this arrangement, it can be a combination of the motor 31 and the screw rod, or a combination of the motor 31 and the gear and rack.

[0048] In order to facilitate the manufacture and assembly of the slider 321. Preferably, the slider 321 includes a first block 3211, a second block 3212 connected and synchronized with the first block 3211, a clamping block 32111 is arranged in the first block 3211, and a transmission spring 322 is arranged in the second block 3212. Preferably, one of the first block 3211 and the second block 3212 is provided with a limiting groove 32121, and the other is provided with a limiting block 32112, and the limiting block 32112 is embedded in the limiting groove 32121. Such a configuration can facilitate the assembly of the first block 3211 and the second block 3212 and enable them to be linked together.

[0049] In order to make the slider 321 relatively firm after being locked, preferably, the housing 1 is provided with a guide plate 34 , which is parallel to the movement direction of the first sub-block 3211 and abuts against the first sub-block 3211 .

[0050] In addition, it should be noted that, in the actual normal use of the smart lock body with anti-pry function, the existing fake lock core can also be used to unlock the door normally. That is, when the real lock core is opened by the adapted key, the real lock core is linked to the transmission bar, so that the transmission bar drives the straight groove 333 (i.e., the inner hole) of the lock core 33 to rotate, thereby realizing the normal door opening.

[0051] The present invention also includes a door, comprising the smart lock body with anti-pry function.

[0052] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
