Description

Technical Field

[0001] The utility model relates to the technical field of smart locks, and in particular to a smart lock and an anti-theft door. Background Art

[0002] In order to improve the anti-theft performance, the smart lock in the related art has an arming mode. When the user goes out, when the smart lock is locked and the arming mode is turned on, if the thief enters the room through the window and unlocks the smart lock from the room, the arming function will be triggered and the smart lock will automatically alarm. After the user successfully opens the door by any unlocking method outdoors, the arming mode will be automatically released.

[0003] In the related art, the handle of the smart lock is installed indoors, a magnet is installed on the handle, and a Hall element is installed inside the smart lock. The distance between the Hall element and the magnet can cause the voltage of the Hall element to change, and then it can sense whether the handle is moved. When the handle in the room is turned, the distance between the magnet and the Hall element changes, the voltage in the Hall element changes, and the voltage change triggers the alarm.

[0004] However, the magnet needs to be kept at a certain distance from the iron part to prevent the magnet from being demagnetized or the iron part from being magnetized, which would cause the distance sensing function with the Hall element to fail. The existing smart locks are still mainly made of iron, so the stability of detecting the deployment through the distance sensing between the magnet and the Hall element is poor. Utility Model Content

[0005] In view of this, the utility model provides a smart lock and an anti-theft door to solve the problem of improving the stability of defense detection.

[0006] In the first aspect, the utility model provides a smart lock, including a lock shell, a rotating shaft, an alarm device and a toggle assembly, the lock shell is provided with a through hole; one end of the rotating shaft passes through the through hole and is rotatably connected thereto, the rotating shaft is suitable for rotating and switching between an initial position and a preset position, and one end of the rotating shaft located on the outside of the lock shell is connected to a handle; the alarm device includes a switch, and the switch is arranged in the lock shell; the toggle assembly is arranged in the lock shell and connected to the rotating shaft, and when the rotating shaft is rotated to the preset position, the toggle assembly toggles the switch.

[0007] Beneficial effect: After the smart lock is locked and the arming mode is turned on, the shaft is in the initial position. When the handle in the room is rotated, the handle drives the shaft to rotate, the shaft drives the toggle component to rotate, the toggle component touches the switch, and after the shaft rotates to the preset position, the switch turns on the alarm device to sound an alarm. Mechanical transmission is used between the handle, shaft and toggle component to improve the stability of arming detection.

[0008] In an optional embodiment, the toggle assembly includes a toggle member and a connecting member, the toggle member is connected to the rotating shaft, the first end of the connecting member is rotatably connected to the alarm device through a rotating member, the second end of the connecting member corresponds to the toggle member, and the switch corresponds to the connecting member; when the rotating shaft is in an initial position, the toggle member and the connecting member have no pressure contact or are disengaged, and the connecting member and the switch have no pressure contact or are disengaged; when the rotating shaft is in a preset position, the toggle member and the connecting member are against each other, and the connecting member and the switch are against each other.

[0009] When the shaft is in the initial position, there is no pressure contact or separation between the toggle member and the connecting member, and there is no pressure contact or separation between the connecting member and the switch, so there is no pressure between the toggle member and the switch, and the alarm will not be activated. The shaft drives the toggle member to rotate, and when the shaft rotates to the preset position, the toggle member and the connecting member abut against each other, generating pressure between them, and then driving the connecting member to rotate around its first end, so that the connecting member abuts against the switch, pressing the switch, and activating the alarm device to alarm. The transmission is through the mechanical structure, and the stability is stronger.

[0011] The toggle member rotates with the rotating shaft, and the second end of the connecting member corresponds to the edge of the notch on the toggle member. When the rotating shaft drives the toggle member to rotate, the second end of the connecting member slides and abuts against the edge of the notch. When the second end of the connecting member abuts against different positions on the notch, the degree of pressure of the connecting member on the switch is different. The farther away from the bottom end of the notch, the greater the pressure. Therefore, as the toggle member rotates, the second end of the connecting member makes an arc motion with the first end as the center, and can press the switch. When the rotating shaft rotates to the preset position, the switch can be turned on to turn on the alarm device.

[0012] In an optional embodiment, the edge of the notch is configured to be arc-shaped, and the second end of the connecting piece corresponds to the concave surface of the notch.

[0014] In an optional embodiment, a protrusion is provided on the toggle member, and the second end of the connecting member corresponds to the edge of the protrusion.

[0015] The toggle member rotates with the rotating shaft, and the second end of the connecting member corresponds to the edge of the protrusion set on the toggle member. When the rotating shaft drives the toggle member to rotate, the second end of the connecting member slides and abuts against the edge of the protrusion. When the second end of the connecting member abuts against different positions on the protrusion, the degree of pressure of the connecting member on the switch is different. The closer to the top of the protrusion, the greater the pressure. Therefore, as the toggle member rotates, the second end of the connecting member makes an arc motion with the first end as the center, and then can press the switch. When the rotating shaft rotates to the preset position, the switch can be turned on to turn on the alarm device.

[0016] In an optional embodiment, the edge of the protrusion is configured to be arc-shaped.

[0017] The raised arc edge can make the sliding contact with the second end of the connecting piece smoother and prevent jamming.

[0018] In an optional embodiment, the second end of the connecting member is bent to form an arc-shaped abutment portion, and the convex surface of the arc-shaped abutment portion corresponds to the toggle member.

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] The sensing distance between the Hall sensor and the magnet directly affects the sensing performance. The sensing distance between the Hall sensor and the magnet is set based on the working principle of the Hall effect and the attenuation characteristics of the magnetic field. When the magnet approaches the Hall sensor, the change in the magnetic field will cause the change in the output voltage of the Hall sensor, thereby realizing the sensing function. However, the size of the magnetic field is affected by the magnet, and the metal material will affect the magnetism of the magnet. Therefore, the alarm triggered by the sensing distance between the Hall sensor and the magnet has poor stability.

[0034] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0035] According to an embodiment of the utility model, on the one hand, a smart lock is provided, including a lock shell 1, a rotating shaft 2, an alarm device 3 and a toggle assembly 4, the lock shell 1 is provided with a through hole; one end of the rotating shaft 2 passes through the through hole and is rotatably connected thereto, the rotating shaft 2 is suitable for rotating and switching between an initial position and a preset position, and one end of the rotating shaft 2 located on the outside of the lock shell 1 is connected to a handle 8; the alarm device 3 includes a switch 301, and the switch 301 is arranged in the lock shell 1; the toggle assembly 4 is arranged in the lock shell 1 and connected to the rotating shaft 2, and when the rotating shaft 2 is rotated to the preset position, the toggle assembly 4 toggles the switch 301.

[0036] After the smart lock is locked and the arming mode is turned on, the shaft 2 is located in the initial position. When the handle 8 in the room rotates, the handle 8 drives the shaft 2 to rotate, the shaft 2 drives the toggle component 4 to rotate, and the toggle component 4 touches the switch 301. After the shaft 2 rotates to the preset position, the switch 301 turns on the alarm device 3 to sound an alarm. Mechanical transmission is used between the handle 8, the shaft 2 and the toggle component 4 to improve the stability of the arming detection.

[0037] In some embodiments, the handle 8 is fixed on the rotating shaft 2 .

[0038] In one embodiment, the toggle assembly 4 includes a toggle member 401 and a connecting member 402, the toggle member 401 is connected to the rotating shaft 2, the first end of the connecting member 402 is rotatably connected to the alarm device 3 through a rotating member, the second end of the connecting member 402 corresponds to the toggle member 401, and the switch 301 corresponds to the connecting member 402; when the rotating shaft 2 is in the initial position, the toggle member 401 and the connecting member 402 are not in pressure contact or disengagement, and the connecting member 402 and the switch 301 are not in pressure contact or disengagement; when the rotating shaft 2 is in the preset position, the toggle member 401 and the connecting member 402 are against each other, and the connecting member 402 and the switch 301 are against each other. When the rotating shaft 2 is in the initial position, there is no pressure contact or disengagement between the toggle member 401 and the connecting member 402, and at the same time, there is no pressure contact or disengagement between the connecting member 402 and the switch 301, so that there is no pressure between the toggle member 401 and the switch 301, and the alarm will not be turned on. The rotating shaft 2 drives the toggle member 401 to rotate. When the rotating shaft 2 rotates to a preset position, the toggle member 401 abuts against the connecting member 402, and pressure is generated therebetween, thereby driving the connecting member 402 to rotate around its first end, so that the connecting member 402 abuts against the switch 301, pressing the switch 301 to activate the alarm device 3 to sound an alarm. The transmission is through a mechanical structure, and the stability is stronger.

[0039] In some embodiments, after the smart lock is locked and the arming mode is turned on, when the rotating shaft 2 is in the initial position, there is no pressure contact between the toggle member 401 and the connecting member 402. At the same time, there is no pressure contact between the connecting member 402 and the switch 301. The handle 8 can be rotated to directly drive the connecting member 402 to press the switch 301 and turn on the alarm with high sensitivity.

[0040] In some embodiments, after the smart lock is locked and the arming mode is turned on, when the shaft 2 is in the initial position, there is no pressure contact between the toggle member 401 and the connecting member 402. At the same time, the connecting member 402 is disengaged from the switch 301. The handle 8 is rotated to a certain extent so that the shaft 2 is located in the preset position. The toggle member 401 drives the connecting member 402 to move, and the connecting member 402 presses the switch 301 to turn on the alarm, thereby improving the fault tolerance rate and preventing false alarms caused by the shaking of the handle 8 due to wind or slight shaking.

[0041] In some embodiments, after the smart lock is locked and the arming mode is turned on, when the shaft 2 is in the initial position, the toggle member 401 and the connecting member 402 are disengaged. At the same time, there is no pressure contact between the connecting member 402 and the switch 301. The handle 8 is rotated to a certain extent so that the shaft 2 is located in the preset position. The toggle member 401 drives the connecting member 402 to move, and the connecting member 402 presses the switch 301 to turn on the alarm, thereby improving the fault tolerance rate and preventing false alarms caused by the shaking of the handle 8 due to wind or slight shaking.

[0042] In some embodiments, after the smart lock is locked and the arming mode is turned on, when the shaft 2 is in the initial position, the toggle member 401 and the connecting member 402 are disengaged, and at the same time, the connecting member 402 and the switch 301 are disengaged. The handle 8 is rotated to a certain extent so that the shaft 2 is located in the preset position, the toggle member 401 drives the connecting member 402 to move, and the connecting member 402 presses the switch 301 to turn on the alarm.

[0043] In some embodiments, the toggle member 401 is fixed or clamped on the rotating shaft 2 .

[0044] In one embodiment, a notch 6 is provided on the toggle member 401, and the second end of the connecting member 402 corresponds to the edge of the notch 6. The toggle member 401 rotates with the shaft 2, and the second end of the connecting member 402 corresponds to the edge of the notch 6 provided on the toggle member 401. When the shaft 2 drives the toggle member 401 to rotate, the second end of the connecting member 402 slides and abuts against the edge of the notch 6. When the second end of the connecting member 402 abuts against different positions on the notch 6, the connecting member 402 presses the switch 301 to different degrees. The farther away from the bottom end of the notch 6, the greater the pressing degree. Therefore, as the toggle member 401 rotates, the second end of the connecting member 402 moves in an arc with the first end as the center, thereby pressing the switch 301. When the shaft 2 rotates to a preset position, the switch 301 can be turned on, and the alarm device 3 is turned on.

[0045] In one embodiment, the edge of the notch 6 is configured to be arc-shaped, and the second end of the connector 402 corresponds to the concave surface of the notch 6. The notch 6 is configured to be arc-shaped so that the second end of the connector 402 can slide and abut against the notch 6 more smoothly to prevent jamming.

[0046] In some embodiments, after the smart lock is locked and the arming mode is turned on, the shaft 2 is in the initial position, the second end of the connector 402 abuts against the bottom end of the concave surface of the notch 6, the switch 301 and the connector 402 are in pressure-free contact, different positions on the notch 6 are at different distances from the switch 301, and the bottom end of the notch 6 is farthest from the switch 301. When the handle 8 rotates, the toggle member 401 rotates, and the position where the second end of the connector 402 abuts against the notch 6 changes, so that the connector 402 is close to the switch 301, and pressure is generated between the connector 402 and the switch 301, pressing the switch 301. When the shaft 2 rotates to the preset position, the alarm device 3 is turned on.

[0047] In one embodiment, a protrusion 7 is provided on the toggle member 401, and the second end of the connecting member 402 corresponds to the edge of the protrusion 7. The toggle member 401 rotates with the shaft 2, and the second end of the connecting member 402 corresponds to the edge of the protrusion 7 provided on the toggle member 401. When the shaft 2 drives the toggle member 401 to rotate, the second end of the connecting member 402 slides and abuts against the edge of the protrusion 7. When the second end of the connecting member 402 abuts against different positions on the protrusion 7, the connecting member 402 presses the switch 301 to different degrees. The closer to the top of the protrusion 7, the greater the pressing degree. Therefore, as the toggle member 401 rotates, the second end of the connecting member 402 moves in an arc with the first end as the center, thereby pressing the switch 301. When the shaft 2 rotates to a preset position, the switch 301 can be turned on and the alarm device 3 is turned on.

[0048] In some embodiments, after the smart lock is locked and the arming mode is turned on, the shaft 2 is in the initial position, the second end of the connector 402 abuts against the bottom end of the protrusion 7, the switch 301 and the connector 402 are in contact without pressure, different positions on the protrusion 7 are at different distances from the switch 301, and the top of the protrusion 7 is closest to the switch 301. When the handle 8 rotates, the toggle member 401 rotates, and the position where the second end of the connector 402 abuts against the protrusion 7 changes, so that the connector 402 is close to the switch 301, and pressure is generated between the connector 402 and the switch 301, pressing the switch 301. When the shaft 2 rotates to the preset position, the alarm device 3 is turned on.

[0049] In one embodiment, the edge of the protrusion 7 is configured to be arc-shaped, so that the sliding contact with the second end of the connecting member 402 can be smoother and prevent jamming.

[0050] In one embodiment, the second end of the connecting member 402 is bent to form an arcuate abutment, and the convex surface of the arcuate abutment corresponds to the toggle member 401. When the toggle member 401 rotates with the shaft 2, the arcuate abutment and the toggle member 401 slide relative to each other more smoothly, avoiding jamming during sliding.

[0051] In some embodiments, the convex surface of the arc-shaped abutment joint of the connecting member 402 slides against the concave surface of the notch 6 with an arc-shaped edge, making the sliding smoother and facilitating the contact between the top end of the convex surface of the arc-shaped abutment joint and the bottom end of the concave surface of the notch 6.

[0052] In some embodiments, the convex surface of the arc-shaped abutment joint of the connecting member 402 slides against the convex surface of the protrusion 7 with an arc-shaped edge, making the sliding smoother and facilitating the contact between the top end of the convex surface of the arc-shaped abutment joint and the top end of the convex surface of the protrusion 7.

[0053] In some embodiments, the toggle member 401 can be made of a plate, and the specific structure can be a circular plate, an arc-shaped plate, a square plate, or a polygonal plate. An arc-shaped notch 6 is opened on the edge of the plate. By setting the notch 6, an uneven structure is formed on the edge of the plate. When the arc-shaped abutment head of the connecting member 402 slides and abuts against the notch 6, the connecting member 402 is driven to move close to the switch 301, pressing the switch 301. The edge of the plate is set to an uneven structure to improve the sensitivity.

[0054] In some embodiments, when the edge of the plate used for the toggle member 401 is a straight edge, the notch 6 and the protrusion 7 may not be provided. When the plate rotates with the shaft 2, the straight edge will drive the driving connector 402 to move closer to the switch 301 and press the switch 301.

The alarm is installed on the inner wall of the shell and the switch 301 passes through the through hole. The switch 301 is electrically connected to the alarm. The first end of the connector 402 is rotatably connected to the shell through a rotating member. The alarm is installed in the shell, and the shell has a protective effect on the alarm. It is more convenient for the connector 402 to be rotatably connected to the shell through the rotating member.
