[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The drive assembly and the rotary disk type electronic password padlock provided in the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the driving assembly of the embodiment of the present invention is used for a rotary electronic password padlock, and the driving assembly includes: a motor 8, a bracket 9, a torsion spring 10 and a transmission block 11.

[0031] Among them, the motor 8 is a hollow cup motor. It should be noted that the driving mechanism in the current electronic padlocks all uses a reduction motor as the unlocking drive, but the resistance of the reduction motor is large, so that the motor works for about 1 second when the series of locks are unlocked; and the cost of the variable speed motor is high, the structure of the reduction motor is complex, and the failure rate of the gear box thereon is high, which makes the cost of the lock high and the user experience poor. The motor 8 in the present invention uses a hollow cup motor, which only takes 50 milliseconds to work, and has a simple structure and high reliability, thereby reducing the cost of the lock and improving the user experience. Therefore, the present invention adopts the domestic first hollow cup motor 8 drive mechanism to realize the low-power application of the lock. Specifically, the hollow cup motor can be a 6mm hollow cup motor. The ordinary 6MM hollow cup motor plus other structures of the present application can realize the locking of the smart lock. The drive component of the present invention has the advantages of low cost, micro power consumption, small size, and high reliability.

[0032] Furthermore, the driving assembly also includes: a bracket 9, which is arranged on the periphery of the motor 8; a torsion spring 10, which is sleeved on one side of the bracket 9, and one end of the torsion spring 10 is clamped on the periphery of the motor 8; a transmission block 11, which is sleeved on the output shaft of the motor 8, and the transmission block 11 includes an integrally formed transmission head 111 and a flat portion 112, and the transmission head 111 is connected to the motor 8; when the rotary electronic password padlock is in a locked state, the other end of the torsion spring 10 abuts against the plane of the flat portion 112.

[0033] Specifically, if Figure 1 As shown in FIG. 1 , when the rotary electronic combination padlock is in a locked state, the other end of the torsion spring 10 abuts against the plane of the flat portion 112. When the rotary electronic combination padlock is unlocked, the motor 8 rotates, the transmission block 11 rotates accordingly, and the flat portion 112 pushes the other end of the torsion spring 10 away, and stops after moving to 90 degrees. Figure 2 When the rotary electronic password padlock is changed from the locked state to the unlocked state, the motor 8 is reversed by 90 degrees to reset, and the torsion spring 10 presses the flat portion 112 of the transmission block 11 again.

[0034] According to one embodiment of the present invention, Figure 3 As shown, the driving assembly also includes: a first limit block 12, the circular side of the first limit block 12 is provided with two opposite circular blind holes, and the flat portion 111 is sleeved with the first limit block 12; two locking tongues 15, the two locking tongues 15 are arranged opposite to each other, a compression spring 16 is arranged between the two locking tongues 15, and two cylinders are arranged on the locking tongue 15, one of the cylinders is suitable for docking with the circular blind hole of the first limit block 12, and the other cylinder is suitable for sleeved with the compression spring 16.

[0035] Specifically, if Figure 1 and Figure 3As shown, when the rotary electronic password padlock is unlocked, the motor 8 rotates, the transmission block 11 rotates accordingly, the flat portion 112 pushes the other end of the torsion spring 10 away, and stops after moving to 90 degrees. At this time, the first limit block 12 also rotates 90 degrees, and the two holes on the side correspond to the cylinder on the lock tongue 15. When the lock tongue 15 is pressed and moved, the cylinder on the lock tongue 15 enters the circular blind hole of the first limit block 12; when the rotary electronic password padlock is turned from a locked state to an unlocked state, the compression spring 16 on the lock tongue 15 is released, and the compression spring 16 locks the lock tongue 15. The tongue 15 is pushed out of the circular hole of the first limit block 12. At this time, the motor 8 reverses 90 degrees to reset, and the first limit block 12 is rotated 90 degrees in the opposite direction. The circular hole on the side leaves the cylindrical relative position of the lock tongue 15. At this time, the torsion spring 10 presses the flat portion 112 of the transmission block 11 again, so that the first limit block 12 can avoid inertial displacement when it is subjected to external vibration force. At this time, since the circular hole of the first limit block 12 has left the cylindrical relative position of the lock tongue 15, the cylinder of the lock tongue 15 abuts against the side wall of the first limit block 12, and the lock tongue 15 cannot continue to move.

[0036] In summary, according to the driving component of the embodiment of the present invention, a hollow cup motor is used for driving. When the rotary electronic password padlock is in a locked state, the other end of the torsion spring abuts against the plane of the flat portion; when the rotary electronic password padlock is unlocked, the motor rotates, the transmission block rotates accordingly, and the flat portion pushes the other end of the torsion spring away, and stops after moving to a certain degree; when the rotary electronic password padlock is changed from a locked state to an unlocked state, the motor reverses 90 degrees for reset, and the torsion spring presses the flat portion 1 of the transmission block again. Therefore, the driving component is driven by a hollow cup motor, the driving time is short, and the structure is simple and the reliability is high, so that the cost of the lock can be reduced and the user experience can be improved; the torsion spring can avoid the problem of inertial displacement of the driving component, thereby improving reliability.

[0037] Corresponding to the above embodiment, the present invention further proposes a rotary disk type electronic password padlock.

[0038] The current rotary password padlock is purely mechanical and cannot be opened or managed electronically. When the fixed password is forgotten, it can only be broken and dismantled. When the lock is not used for a long time, it is very easy to forget the password, which causes inconvenience to the user. At the same time, there are also some electronic padlocks that use keyboards and direction keys to enter passwords, but this series of padlocks has very poor security protection. The key for entering the password divides the lock plane into several small areas. At the same time, the key made of plastic material is very easy to be damaged, and the service life cannot be compared with the turntable made of metal material. In addition, the drive mechanism in the existing electronic padlocks all uses a reduction motor as the unlocking drive, but the resistance of the reduction motor is large, which makes the motor work for about 1 second when the series of locks are unlocked; and the cost of the variable speed motor is high, the structure of the reduction motor is complex, and the failure rate of the gear box on it is high, which makes the cost of the lock high and the user experience poor. In addition, the drive structure in the existing electronic padlock is complex, and when it is subjected to external forces such as vibration, it is easy to have inertial displacement, resulting in poor reliability.

[0039] In order to solve the above technical problems, the present invention proposes a rotary disk type electronic password padlock, which adopts a metal-integrated rotary disk type password input device to improve the service life and protection ability of the product and has a simple structure.

[0040] like Figure 4 As shown, the rotary disk type electronic password padlock according to the embodiment of the present invention comprises: a lock beam 17 and a lock body.

[0041] The lock body includes: a lock shell 2, a mounting seat 13, a password input component, a drive component and a power supply component of the above embodiment. The drive component is arranged in the lock shell 2, one end of the drive component is connected to the lock beam 17, the upper part of the lock beam 17 extends to the upper part of the lock body, and both ends of the lock beam 17 are movably buckled with the drive component. When the lock beam 17 and the drive component are in a buckled connection state, the lock is completed.

[0042] Specifically, Figure 1 and Figure 4As shown, when the rotary electronic password padlock is unlocked, the motor 8 rotates, the transmission block 11 rotates accordingly, the flat portion 112 pushes the other end of the torsion spring 10 away, and stops on the arc surface after moving to 90 degrees. At this time, the first limit block 12 also rotates 90 degrees, and the two holes on the side correspond to the cylinder on the lock tongue 15. At this time, the lock beam 17 is pulled, and the lock tongue 15 is pressed and moved by the arc groove on the lock beam 17. The cylinder on the lock tongue 15 enters the circular blind hole of the first limit block 12, and the lock is opened; when the rotary electronic password padlock is unlocked, the motor 8 rotates, the transmission block 11 rotates accordingly, and ... When the sub-code padlock changes from a locked state to an unlocked state, after the lock beam 17 is pressed down, the compression spring 16 on the lock tongue 15 is released, pushing the lock tongue 15 out of the circular hole of the first limit block 12 and abutting against the groove of the lock beam 17. At this time, the motor 8 reverses 90 degrees to reset, and the first limit block 12 is rotated 90 degrees in the opposite direction. The circular hole on the side leaves the cylindrical relative position of the lock tongue 15. At this time, the torsion spring 10 presses the flat portion 112 of the transmission block 11 again, so that the first limit block 12 withstands external vibration force to avoid inertial displacement. When the lock beam 17 is pulled again, since the circular hole of the first limit block 12 has been separated from the cylindrical relative position of the lock tongue 15, the cylinder of the lock tongue 15 abuts against the side wall of the first limit block 12, and the lock tongue 15 cannot continue to move, thereby realizing the locking function. The locked state of the electronic code padlock is as follows: Figure 6 As shown, the unlocking status of the electronic password padlock is as follows Figure 7 shown.

[0043] like Figure 4 and Figure 5 As shown, the password input component includes a dial knob 1, a dial limit block 4, a dial contact piece 6 and a circuit board 7. The dial knob 1 is arranged on the outer surface of the lock shell 2, and passes through the lock shell 2 and is riveted to the dial limit block 4. The dial knob 1 is provided with numbers 0-9; the dial limit block 4 is provided with a dial contact piece 6, and the dial contact piece 6 abuts against the circuit board 7; the circuit board 7 is electrically connected to the drive component, and the circuit board 7 is fixedly connected to the mounting seat 13. The user can pre-set the unlocking password. When the user unlocks the lock, the password is input through the dial knob 1, and the corresponding dial contact piece 6 can contact the circuit board 7 to complete the password input. The circuit board 7 outputs a corresponding unlocking signal to make the motor 8 in the drive component run, so that the drive component and the lock beam 17 are in a buckled connection state and the state is changed to a separated state, thereby completing the unlocking.

[0044] The power supply assembly is arranged on the mounting seat 13, and the power supply assembly is electrically connected to the driving assembly and the circuit board 7 respectively. The power supply assembly can supply power to the driving assembly and the circuit board 7.

[0045] According to one embodiment of the present invention, three groups of brushes are arranged on the dial contact piece 6 .

[0046] Further, according to an embodiment of the present invention, a trigger circuit is provided on the circuit board 7, and the trigger circuit is formed by three concentric circles, two of which are divided into 10 areas.

[0047] Specifically, when the turntable knob 1 is rotated, the brush on the dial contact piece 6 contacts the three concentric circles on the circuit board 7, thereby realizing the input of the password.

[0048] According to an embodiment of the present invention, the password input assembly further comprises a clamping spring 5, which is arranged between the turntable limit block 4 and the dial contact piece 6. The turntable limit block 4 can be locked and fixed by the clamping spring 5.

[0049] According to an embodiment of the present invention, arc grooves are provided at the lower parts of the two opposite sides of the lock beam 17, and the arc grooves are buckled with the driving assembly to realize the buckling and fixing of the lock beam 17 and the lock body.

[0050] According to one embodiment of the present invention, Figure 4 As shown, the power supply assembly includes: a battery compartment 18; a battery 19, which is installed in the battery compartment 18; and a battery cover 21, which is connected to the rear cover 20 of the lock body by screws 22.

[0051] According to one embodiment of the present invention, the battery 19 is a 2032 battery.

[0052] According to one embodiment of the present invention, Figure 3 and Figure 4 As shown, the lock body further includes: a plug 14, which is fixedly connected to the mounting seat 13, and the plug 14 is also used to block the drive assembly. Figure 3 As shown, the block 14 can block the first limit block 12 in the driving assembly.

[0053] According to one embodiment of the present invention, the motor 8 is a coreless motor 8 .

[0054] Specifically, current electronic padlocks all use a reduction motor as an unlocking drive, but the motor of this series of locks works for about 1 second when unlocking, and the battery needs to be recharged or replaced after 3 months to 1 year of use, which causes great inconvenience to users. This invention uses a hollow cup motor to drive the unlocking, and the motor 8 only needs 50 milliseconds to work, which is 0.05 times the traditional power consumption. Therefore, a 2032 battery can be used for a long time for up to 2 years, which greatly facilitates user use. Therefore, the present invention adopts the domestically pioneered hollow cup motor 8 drive mechanism to achieve low-power application of locks, greatly extending the number of times the battery 19 is unlocked and the standby time, thereby avoiding frequent replacement of the battery 19.

[0055] In summary, according to the rotary disc type electronic password padlock of the embodiment of the present invention, the password is input through the rotary disc knob, and the corresponding dial contact piece can contact the circuit board to complete the password input. The circuit board outputs the corresponding unlocking signal to operate the driving component, so that the driving component and the lock beam are connected to each other in a buckled state, thereby completing the unlocking. Therefore, the rotary disc type electronic password padlock adopts a metal-integrated rotary disc type password input device to improve the service life and protection ability of the product; by using a hollow cup motor for driving, the driving time is short, and the structure is simple and reliable, thereby reducing the cost of the lock and improving the user experience; the torsion spring can avoid the problem of inertial displacement of the driving component, thereby improving reliability.
