Abstract
Description
[Technical field]
[0001] The utility model relates to a lock, in particular to an intelligent electronic padlock. [Background technology]
[0002] Smart electronic padlocks are the traditional padlocks with electronic control circuits added. Smart electronic padlocks get rid of the traditional padlocks with only mechanical keys, and can expand fingerprints, passwords, cards, mobile phones and other unlocking methods. Not only does it diversify the unlocking methods, but it also breaks the defects of mechanical keys that are easy to miss and the small number of keys. And because of the addition of electronic control, it can also be expanded in wireless communication, making remote control and real-time monitoring possible. The benefits of smart electronic padlocks are unquestionable, but how to realize the combination of mechanical and electronic parts is relatively cumbersome. The space of the padlock is limited, so the combination method is required to be as simple as possible, and because it is used frequently for a long time, the reliability requirements are also very high.
[0003] At present, the more common switch lock control method of smart electronic padlocks on the market is that unlocking is controlled by a motor and locking is achieved by a mechanical structure. This implementation method has relatively high requirements for mechanical coordination, which leads to the actual designed padlock structure with complex mechanical structure and inconvenient assembly.
[0004] The Chinese utility model No. CN215485347U discloses a smart Bluetooth padlock, which relates to the technical field of smart padlocks. The smart Bluetooth padlock includes: a lock body, a lock beam, and an electric drive structure, a control board, a magnet and a Hall sensor arranged in the lock body; the lock body has a space for the lock beam to press down; the magnet is arranged on the lower side of the lock beam and moves relative to the Hall sensor with the movement of the lock beam; the control board is electrically connected to the Hall sensor; when the lock beam is pressed down, the magnet approaches or moves away from the Hall sensor, and the electrical signal output by the Hall sensor changes, thereby waking up the unlocking system running on the control board; after receiving the external unlocking command, the unlocking system controls the electric drive structure to drive the lock beam to move upward to complete the unlocking.
[0005] The Chinese utility model No. CN207436688U discloses an electronic lock safety knob structure with signal feedback, including a panel, a safety knob is arranged on the panel, a Hall sensor is arranged below the safety knob, the Hall sensor is arranged on the panel, a Hall sensor circuit board is connected to the Hall sensor, the Hall sensor circuit board is arranged on the panel, a lower strong magnetic sheet is arranged on one side of the Hall sensor, an upper strong magnetic sheet is arranged above the lower strong magnetic sheet, a magnet fixing plate is arranged on the safety knob, and the upper strong magnetic sheet and the lower strong magnetic sheet are both arranged on the magnet fixing plate. When the safety knob is turned, the Hall sensor can output a feedback signal, so that the electronic lock sends a reminder. When the user does not lift the handle with sufficient force and does not reach the anti-lock state, the user is reminded, so that the user receives the signal to re-lock, thereby improving the safety factor.
[0006] It can be seen that although the combination of Hall sensors and magnets is widely used in locks, there is no relevant report on using them to assist the unlocking working device to complete the locking operation in order to save space, simplify the structure and reduce costs. [Contents of the utility model]

[0010] The electronic control board, the motor, and the plug are all arranged in the lock body, and the motor can drive the plug to insert into or leave the limit groove under the control of the electronic control board;
[0011] Unlocking is achieved when the electronic control board controls the motor to drive the pin to leave the limiting groove;
[0012] The first Hall sensor is arranged on one side of the electronic control board, and can identify the magnetic field of the first magnetic body when the hook is pressed down to the locking point, and sends a first signal to the electronic control board when the magnetic field of the first magnetic body is identified;
[0013] The second Hall sensor is arranged on the other side of the electronic control board, and can identify the magnetic field of the second magnetic body when the hook is pressed down to the locking point, and sends a second signal to the electronic control board when the magnetic field of the second magnetic body is identified;
[0014] When the electronic control board receives the first signal and the second signal, it controls the motor to drive the pin to insert into the limiting groove to achieve locking.

[0019] The embodiment of the utility model provides an intelligent electronic padlock, in which two Hall sensors and two small magnets are used to help the unlocking working device to undertake the locking operation, thereby simplifying the structure, saving space, having reliable performance, and reducing costs.
[0020] The technical solution in the embodiment of the utility model is to solve the above problems, and the overall idea is as follows: two Hall sensors and two small magnets are used to help the unlocking working device to undertake the locking operation, so that the electromechanical parts of the unlocking can be reused to achieve locking, thereby simplifying the structure of the smart electronic padlock, saving space, reliable performance, and reducing costs.
[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0022] See also Figure 1 and Figure 2 As shown, the smart electronic padlock 100 of the utility model includes a lock body 1, a hook 2, an electronic control board 3, a motor 4, a pin 5, a first Hall sensor 61, a second Hall sensor 62, a first magnetic body 71 and a second magnetic body 72; wherein the first magnetic body 71 and the second magnetic body 72 can be magnets.
[0023] The hook 2 has a closed end 21 and an open end 22, the open end 21 is provided with a limiting groove 23, and the first magnetic body 71 is arranged at the closed end 21, and the second magnetic body 72 is arranged at the open end 22;
[0024] The electronic control board 3, the motor 4, and the plug 5 are all arranged in the lock body 1, and the motor 4 can drive the plug 5 to insert into or leave the limit groove 23 under the control of the electronic control board 3;
[0025] When the electronic control board 3 controls the motor 4 to drive the pin 5 to leave the limiting groove 23, unlocking is achieved;
[0026] The first Hall sensor 61 is disposed on one side of the electronic control board 3 (i.e., the side corresponding to the closed end 21), and can identify the magnetic field of the first magnetic body 71 when the hook 2 is pressed down to the locking point, and sends a first signal to the electronic control board 3 when the magnetic field of the first magnetic body 71 is identified;
[0027] The second Hall sensor 62 is arranged on the other side of the electronic control board 3 (i.e., the side corresponding to the opening end 22), and can identify the magnetic field of the second magnetic body 72 when the hook 2 is pressed down to the locking point, and sends a second signal to the electronic control board 3 when the magnetic field of the second magnetic body 72 is identified;
[0028] When the electronic control board 3 receives the first signal and the second signal, it controls the motor 4 to drive the pin 5 to insert into the limiting groove 23 to achieve locking.
[0029] Among them, the Hall sensor is a magnetic field sensor made based on the Hall effect, which can measure the strength, direction and polarity of the magnetic field. When the magnetic field passes through the Hall element of the Hall sensor, the electrons in the Hall element will be affected by the Lorentz force, causing the electrons to move in a certain direction in the Hall element. This movement causes the accumulation of electrons, thereby generating a potential difference on both sides of the Hall element. This potential difference can be detected by the signal processing circuit and converted into information about the strength, direction and polarity of the magnetic field. The Hall sensor can convert this information into digital signals or analog signals for subsequent processing. In the utility model, two magnets provide the magnetic field required for the Hall sensor to identify, so that the Hall sensor is used to detect whether the hook has reached the locking point position. When the hook is pressed to the locking point position, the Hall sensor can identify the magnetic field of the magnet and output a signal. The electronic control board can determine the position of the hook based on the signal.
[0030] Based on the magnetic field induction principle of the Hall sensor, the switch lock working principle of the intelligent electronic padlock of the utility model is as follows:
[0031] Unlocking process: the electronic control board 3 directly controls the motor 4 to move the plug 5 away from the limit groove 23 of the hook 2, and the hook is automatically ejected by the elastic force of the spring 9 below to unlock the padlock.
[0032] Locking process: When locking is required, the hook 2 is pressed to the locking point position. At this time, the two Hall sensors recognize the magnetic fields of the two magnets and output signals to the electronic control board 3. The electronic control board 3 knows that the hook 2 has been pressed into place, and controls the motor 4 to move the pin 5 into the limit slot 23 of the hook 2, thereby achieving locking.
[0033] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
