Description

Technical Field

[0001] The utility model relates to the technical field of electronic padlocks, in particular to a drive component and a rotary disc type electronic password padlock having the same. Background Art

[0002] In the related art, most smart locks that use motor locking use reduction micro motors: ordinary micro motors have very small rotor damping when there is no electricity, and will produce displacement under conditions such as knocking and vibration, and cannot be directly used to achieve lock control locking. The resistance of the reduction motor is large, and the motor works for about 1 second when unlocking, and the power consumption is correspondingly large; in addition, the cost of the variable speed motor is high, the structure of the reduction motor is complex, and its gearbox failure rate is high. Utility Model Content

[0003] The present invention aims to at least partially address one of the technical problems in the related art. To this end, the first object of the present invention is to provide a drive assembly that utilizes a coreless motor for driving, resulting in a short drive time, a simple structure, and high reliability, thereby reducing the cost of the lock and improving the user experience. Furthermore, the torsion spring prevents inertial displacement of the drive assembly, thereby improving reliability.

[0004] The second purpose of the present invention is to provide a rotary disc type electronic password padlock.

[0005] To achieve the above-mentioned purpose, the first embodiment of the present invention proposes a drive assembly, which is used for a rotary disk type electronic password padlock, and the drive assembly includes: a motor, which is a hollow cup motor; a bracket, which is arranged on the outer periphery of the motor; a torsion spring, which is sleeved on one side of the bracket, and one end of the torsion spring is clamped on the outer periphery of the motor; a transmission block, which is sleeved on the output shaft of the motor, and the transmission block includes an integrally formed transmission head and a flat portion, and the transmission head is connected to the motor; when the rotary disk type electronic password padlock is in a locked state, the other end of the torsion spring abuts against the plane of the flat portion.

[0006] According to the drive assembly of the embodiment of the present invention, a coreless motor is used for driving. When the rotary electronic combination padlock is in the locked state, the other end of the torsion spring contacts the plane of the flat portion. When the rotary electronic combination 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 combination padlock is switched from the locked state to the unlocked state, the motor reverses 90 degrees to reset, and the torsion spring presses the flat portion 1 of the transmission block again. Thus, the drive assembly is driven by a coreless motor, has a short driving time, a simple structure, and high reliability, thereby reducing the cost of the lock and improving the user experience. The torsion spring can avoid the problem of inertial displacement of the drive assembly, thereby improving reliability.

[0007] According to one embodiment of the present invention, the drive assembly also includes: a first limit block, the circular side surface of the first limit block is provided with two opposite circular blind holes, and the flat portion is sleeved with the first limit block; two lock tongues, the two lock tongues are arranged opposite to each other, and a compression spring is provided between the two lock tongues, and two cylinders are provided on the lock tongues, one cylinder is suitable for docking with the circular blind hole of the first limit block, and the other cylinder is suitable for sleeved with the compression spring.

[0008] To achieve the above-mentioned objectives, the second embodiment of the present invention proposes a rotary disk type electronic password padlock, comprising: a lock body and a lock beam; the lock body comprises: a lock shell, a mounting seat, a password input assembly, a drive assembly and a power supply assembly; the drive assembly is arranged in the lock shell, one end of the drive assembly is connected to the lock beam, the upper part of the lock beam extends to the top of the lock body, and both ends of the lock beam are movably connected to the drive assembly; the password input assembly comprises a rotary disk knob, a rotary disk limit block, a dial contact and a circuit board, the rotary disk knob is arranged on the outer surface of the lock shell, and passes through the lock shell and is riveted to the rotary disk limit block, the rotary disk knob is provided with numbers 0-9; the dial contact is provided on the rotary disk limit block, and the dial contact abuts against the circuit board; the circuit board is electrically connected to the drive assembly, and the circuit board is fixedly connected to the mounting seat; the power supply assembly is arranged on the mounting seat, and the power supply assembly is electrically connected to the drive assembly and the circuit board respectively.

[0009] According to the rotary dial electronic combination padlock of the present invention, a password is entered via the rotary dial knob, and the corresponding dial contact contacts contact the circuit board to complete the password input. The circuit board then outputs a corresponding unlocking signal to activate the drive assembly, causing the drive assembly to change from a snap-on connection with the lock beam to a separate state, thereby completing the unlocking process. Thus, the rotary dial electronic combination padlock utilizes a metal-integrated rotary dial password input device, which can extend the product's service life and security capabilities. The use of a coreless motor for driving reduces drive time, simplifies the structure, and improves reliability, thereby reducing the cost of the lock and improving the user experience. The torsion spring prevents inertial displacement of the drive assembly, thereby improving reliability.

[0010] In addition, the rotary disc type electronic combination padlock according to the above embodiment of the present invention may also have the following additional technical features:

[0028] The following describes in detail embodiments of the present invention, 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 explain the present invention, and should not be construed as limiting the present invention.

[0029] The drive assembly and the rotary disk type electronic combination padlock proposed 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 utility model 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 relatively 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 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 domestically pioneered hollow cup motor 8 drive mechanism to achieve low-power application of the lock. Specifically, the hollow cup motor can be a 6mm hollow cup motor. An ordinary 6MM hollow cup motor plus other structures of this application can realize the locking of the smart lock. The drive component of the present invention has the advantages of low cost, low power consumption, small size, and high reliability.

[0032] Furthermore, the drive assembly also includes: a bracket 9, which is arranged on the outer 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 stuck on the outer 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, when the rotary electronic combination padlock is in the 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 turned 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 drive 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 lock tongues 15, the two lock tongues 15 are arranged opposite to each other, and a compression spring 16 is provided between the two lock tongues 15, and two cylinders are provided on the lock tongue 15, one of which 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 cylinders 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 the locked state to the 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 is reversed 90 degrees to reset. 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 move further.

[0036] In summary, according to the drive assembly of the embodiment of the present invention, a hollow cup motor is used for driving. When the rotary electronic combination padlock is in the locked state, the other end of the torsion spring contacts the plane of the flat portion. When the rotary electronic combination 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 combination padlock is changed from the locked state to the unlocked state, the motor reverses 90 degrees to reset, and the torsion spring presses the flat portion 1 of the transmission block again. Therefore, the drive assembly is driven by a hollow cup motor, with a short driving time, a simple structure and high reliability, which can reduce the cost of the lock and improve the user experience. The torsion spring can avoid the problem of inertial displacement of the drive assembly, thereby improving reliability.

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

[0038] Current rotary combination padlocks are purely mechanical and cannot be opened or managed electronically. Forgetting the fixed combination requires breaking and unlocking, which is very easy to forget when the lock is not used for a long time, causing inconvenience to the user. Some electronic padlocks also use keyboards and arrow keys for password entry, but these offer poor security. The password entry buttons divide the lock surface into several small areas, and the plastic buttons are easily damaged, making their service life comparable to that of metal rotary padlocks. Furthermore, the drive mechanisms in existing electronic padlocks all use reduction motors for unlocking. However, the resistance of reduction motors is high, resulting in a motor operating time of approximately one second. Furthermore, variable speed motors are expensive and complex, and the gearboxes on these motors have a high failure rate, resulting in high lock costs and a poor user experience. Furthermore, the drive mechanisms in existing electronic padlocks are complex and prone to inertial displacement when subjected to external forces such as vibration, resulting in poor reliability.

[0039] In order to solve the above technical problems, the utility model 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 capability of the product and has a simple structure.

[0040] like Figure 4 As shown, the rotary disk type electronic password padlock of the embodiment of the present utility model includes: a lock beam 17 and a lock body.

[0041] The lock body comprises a lock housing 2, a mounting base 13, a password input assembly, the drive assembly of the aforementioned embodiment, and a power supply assembly. The drive assembly is housed within the lock housing 2, one end of which is connected to a locking beam 17. The upper portion of the locking beam 17 extends above the lock body, and both ends of the locking beam 17 are movably engaged with the drive assembly. When the locking beam 17 and the drive assembly are engaged, the lock is locked.

[0042] Specifically, if 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 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. When the sub-password 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 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, thereby realizing the locking function. The locked state of the electronic password 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 assembly includes a dial knob 1, a dial stop block 4, a dial contact 6, and a circuit board 7. The dial knob 1 is disposed on the outer surface of the lock housing 2 and passes through the lock housing 2 and is riveted to the dial stop block 4. The dial knob 1 is provided with the numbers 0-9; the dial stop block 4 is provided with a dial contact 6, which abuts the circuit board 7; the circuit board 7 is electrically connected to the drive assembly, and the circuit board 7 is fixedly connected to the mounting base 13. The user can pre-set the unlocking password. When the user unlocks the lock, they enter the password through the dial knob 1. The corresponding dial contact 6 contacts the circuit board 7 to complete the password input. The circuit board 7 outputs a corresponding unlocking signal to activate the motor 8 in the drive assembly, causing the drive assembly to disconnect from the locking beam 17, thereby completing the unlocking.

[0044] The power supply assembly is arranged on the mounting base 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 an embodiment of the present invention, three groups of brushes are provided on the dial contact piece 6 .

[0046] Furthermore, 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 dial 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 on the lower parts of the two opposite sides of the lock beam 17, and the arc grooves are buckled with the driving assembly to achieve the buckling and fixation 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; a battery cover 21, which is connected to the back 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 is also used to block the drive assembly. Figure 3 As shown, the block 14 can block the first limit block 12 in the drive 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 the unlocking drive, but the motor of this series of locks only works for about 1 second when unlocking, and after 3 months to 1 year of use, it needs to be recharged or the battery replaced, causing great inconvenience to the user. The utility model uses a hollow cup motor to drive the unlocking, and the motor 8 only takes 50 milliseconds to work, which is 0.05 times the power consumption of traditional methods. Therefore, a 2032 battery can be used for a long time for up to 2 years, which is very convenient for users. Therefore, the utility model adopts the domestically pioneered hollow cup motor 8 drive mechanism to achieve low-power application of the lock, greatly extending the number of times the battery 19 can be unlocked and the standby time, thereby avoiding frequent battery replacement 19.

[0055] In summary, according to the embodiment of the present invention, the rotary disc type electronic password padlock, by inputting the password through the rotary dial knob, the corresponding dial contact can contact the circuit board to complete the password input, and the circuit board outputs a corresponding unlocking signal to activate the drive assembly, so that the drive assembly and the lock beam are connected to each other and then separated, thereby completing the unlocking. As a result, the rotary disc type electronic password padlock adopts an integrated metal rotary disc type password input device, which can improve the product's service life and protection capabilities; 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 drive assembly, thereby improving reliability.
