[0027] 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.

[0028] The following describes a knob-type visual electronic password padlock provided by an embodiment of the present invention with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the knob-type visual electronic password padlock implemented by the present invention includes: a lock beam 19 and a lock body.

[0030] The lock body includes: a lock shell 4, a mounting seat 10, a password input component, a display component, a drive component and a power supply component.

[0031] The drive assembly is disposed in the lock housing 4, one end of the drive assembly is connected to the lock beam 19, the upper portion of the lock beam 19 extends to the upper portion of the lock body, and both ends of the lock beam 19 are movably buckled with the drive assembly. When the lock beam 19 and the drive assembly are in a buckled connection state, the lock is completed. It should be noted that arc grooves are provided at the lower portions of the two opposing sides of the lock beam 19, and the arc grooves are buckled with the drive assembly to realize the buckling and fixing of the lock beam 19 and the lock body.

[0032] Furthermore, if Figure 1 As shown, the password input component includes: a knob 2, a limiter 5, a shift fork 8 and a circuit board 9; the knob 2 is arranged on the outer surface of the lock housing 4, and passes through the lock housing 4 and is riveted to the limiter 5; the shift fork 8 is sleeved with the limiter 5, and is clamped with the trigger circuit on the circuit board 9; the circuit board 9 is electrically connected to the driving component, and the circuit board 9 is fixedly connected to the mounting seat 10. The display component is arranged on the circuit board 9, and when the knob 2 rotates, the shift fork 8 shifts the trigger circuit to make the display component display numbers. An observation window is arranged on the lock housing 4, and the position of the observation window is opposite to the display component, and a display lens 3 is installed on the observation window.

[0033] Specifically, the user can pre-set the unlocking password. When the user unlocks the door, the password is input by rotating the knob 2. The rotation of the knob 2 drives the fork 8 to rotate. The fork 8 toggles the trigger circuit on the circuit board 9. The trigger circuit generates an ascending or descending signal. The circuit board 9 makes the display component display numbers in ascending or descending order according to the ascending or descending signal. The user can observe the numbers displayed by the display component through the display lens 3 on the observation window. After completing the input of the unlocking password, the circuit board 9 outputs the corresponding unlocking signal to the drive component. The drive component operates to change the lock beam 19 and the drive component from the buckled connection state to the disengaged state. The user pulls down the lock body to complete the unlocking. It should be noted that the display component can be a device that can display numbers, such as a digital tube or an LCD screen. The display component is covered with a digital cover 6.

[0034] Furthermore, a power supply assembly is arranged on the mounting seat 10, and the power supply assembly is electrically connected to the driving assembly and the circuit board 9 respectively. The power supply assembly can supply power to the driving assembly and the circuit board 9.

[0035] According to one embodiment of the present invention, Figure 2 As shown, the trigger circuit includes two short contact pieces 91 and one long contact piece 92 . The long contact piece 92 is arranged in the middle of the two short contact pieces 91 , and the long contact piece 92 is arranged horizontally.

[0036] Further, according to one embodiment of the present invention, Figure 2 As shown, the shift fork 8 includes 10 equally divided gears, and the center of the shift fork 8 and the long contact piece 92 are in the same horizontal plane; in the initial state, the long contact piece 92 is engaged with a tooth root of the shift fork 8 .

[0037] Specifically, if Figure 2 As shown, in the initial state, the long contact piece 92 is engaged with a tooth root of the shift fork 8, and the two short contact pieces 91 are respectively on both sides of the long contact piece 92. One of the short contact pieces 91 is disconnected after contacting the long contact piece 92 to generate an ascending signal, and the other short contact piece 91 is disconnected after contacting the long contact piece 92 to generate a descending signal. Figure 3 As shown, the short contact piece 91 above the long contact piece 92 can be set as a descending contact piece, and the short contact piece 91 below the long contact piece 92 can be set as an ascending contact piece. When the knob 2 is rotated clockwise, the fork 8 drives the long contact piece 92 to contact the short contact piece 91 (ascending contact piece) below it. When it rotates one tooth position clockwise, the long contact piece 92 contacts and then disconnects from the short contact piece 91 (ascending contact piece) below it, thereby generating an ascending signal and displaying the password on the display component at the same time, thereby realizing the input of the password.

[0038] According to one embodiment of the present invention, Figure 2As shown, the password input assembly further includes: an elastic paddle 7 , one end of which is connected to the lock housing 4 , and the other end of which is engaged with another tooth root of the shift fork 8 .

[0039] Specifically, if Figure 2 As shown, the other end of the elastic paddle 7 is meshed with another tooth root of the fork 8, and the tooth root engaged with the long contact piece 92 is separated by two teeth. When the knob 2 is turned, the fork 8 rotates, and the tooth top of the fork 8 forces the elastic paddle 7 to deform. When the tooth passes over the top of the elastic paddle 7, the elastic paddle 7 forces the fork 8 to mesh again, thereby realizing the 10-equal positioning function of the fork 8.

[0040] According to one embodiment of the present invention, Figure 1 As shown, the password input component also includes: a confirmation button 1, which is arranged at the center of the knob 2 and is electrically connected to the circuit board 9.

[0041] Specifically, when the user enters the password, the user observes the number displayed on the display component through the display lens 3 at the observation window. When the displayed number is the preset password, the user can press the confirmation button 1 to confirm, thereby sending a confirmation signal to the circuit board 9 to complete the password input. The confirmation button 1 can be used to complete the input of multiple passwords, for example, each password is entered and a confirmation button is pressed once.

[0042] According to one embodiment of the present invention, Figure 4 As shown, the driving assembly includes: a motor 11, which is a hollow cup motor 11, and the motor 11 is installed on the mounting seat 10, and the motor 11 is electrically connected to the circuit board 9; a bracket 12, and the bracket 12 is arranged on the outer periphery of the motor 11; a torsion spring 13, and the torsion spring 13 is sleeved on one side of the bracket 12, and one end of the torsion spring 13 is clamped on the outer periphery of the motor 11; a transmission block 14, and the transmission block 14 is sleeved on the output shaft of the motor 11. The transmission block 14 includes an integrally formed transmission head 141 and a flat portion 142, and the transmission head 141 is connected to the motor 11; when the knob-type visual electronic password padlock is in a locked state, the other end of the torsion spring 13 abuts against the plane of the flat portion 142.

[0043] Specifically, the current driving mechanisms in electronic padlocks all use reduction motors as unlocking drives, but the resistance of reduction motors is large, so that the motor works for about 1 second when the series of locks are unlocked; and the cost of variable speed motors is high, the structure of reduction motors is complex, and the failure rate of the gearboxes thereon is high, which makes the cost of the locks high and the user experience poor. The motor 11 in the present invention uses a coreless 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 coreless motor drive mechanism to achieve low-power application of locks. Specifically, the coreless motor can be a 6mm coreless motor. An ordinary 6mm coreless motor plus other structures of the present application can realize the locking of the smart lock. The drive assembly of the present invention has the advantages of low cost, low power consumption, small size, and high reliability.

[0044] Furthermore, if Figure 4 As shown in FIG. 1 , when the rotary electronic combination padlock is in a locked state, the other end of the torsion spring 13 abuts against the plane of the flat portion 142. When the rotary electronic combination padlock is unlocked, the motor 11 rotates, the transmission block 14 rotates accordingly, and the flat portion 142 pushes the other end of the torsion spring 13 away, and stops after moving to 90 degrees. Figure 5 When the rotary electronic password padlock is changed from the locked state to the unlocked state, the motor 11 is reversed by 90 degrees to reset, and the torsion spring 13 presses the flat portion 142 of the transmission block 14 again.

[0045] According to one embodiment of the present invention, Figure 1 As shown, the driving assembly also includes: a limit block 15, the circular side of the limit block 15 is provided with two opposite circular blind holes, and the flat portion 142 is sleeved with the limit block 15; two locking tongues 16, the two locking tongues 16 are arranged opposite to each other, a compression spring 18 is arranged between the two locking tongues 16, and two cylinders are arranged on the locking tongue 16, one cylinder is suitable for docking with the circular blind hole of the limit block 15, and the other cylinder is suitable for sleeved with the compression spring 18.

[0046] Specifically, when the rotary electronic password padlock is unlocked, the motor 11 rotates, the transmission block 14 rotates accordingly, the flat portion 142 pushes the other end of the torsion spring 13 away, and stops on the arc surface after moving to 90 degrees. At this time, the limit block 15 also rotates 90 degrees, and the two holes on the side correspond to the cylinder on the lock tongue 16. At this time, the lock beam 19 is pulled, and the lock tongue 16 is pressed and moved by the arc groove on the lock beam 19, and the cylinder on the lock tongue 16 enters the circular blind hole of the limit block 15, and the lock is opened; when the rotary disk is unlocked, the transmission block 14 rotates accordingly, and the flat portion 142 pushes the other end of the torsion spring 13 away, and stops on the arc surface after moving to 90 degrees. At this time, the limit block 15 also rotates 90 degrees, and the two holes on the side correspond to the cylinder on the lock tongue 16. At this time, the lock beam 19 is pulled, and the lock tongue 16 is pressed and moved by the arc groove on the lock beam 19, and the cylinder on the lock tongue 16 enters the circular blind hole of the limit block 15, and the lock is opened. When the electronic password padlock changes from a locked state to an unlocked state, after the lock beam 19 is pressed down, the compression spring 18 on the lock tongue 16 is released, pushing the lock tongue 16 out of the circular hole of the limit block 15 and abutting against the groove of the lock beam 19. At this time, the motor 11 reverses 90 degrees to reset, and the limit block 15 is rotated 90 degrees in the opposite direction. The circular hole on the side leaves the cylindrical relative position of the lock tongue 16. At this time, the torsion spring 13 presses the flat portion 142 of the transmission block 14 again, so that the limit block 15 withstands external vibration force to avoid inertial displacement. When the lock beam 19 is pulled again, since the circular hole of the limit block 15 has been separated from the cylindrical relative position of the lock tongue 16, the cylinder of the lock tongue 16 abuts against the side wall of the limit block 15, and the lock tongue 16 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.

[0047] According to one embodiment of the present invention, Figure 1 As shown, the power supply assembly includes: a battery compartment 20; a battery 22, which is installed in the battery compartment 20; and a battery cover 23, which is connected to the rear cover 21 of the lock body by screws 24.

[0048] According to one embodiment of the present invention, the battery 22 is a 2032 battery.

[0049] According to one embodiment of the present invention, Figure 1 As shown, the lock body further includes: a plug 17, which is fixedly connected to the mounting seat 10, and the plug 17 is also used to block the drive assembly. Figure 1 As shown, the blocking block 17 can block the limiting block 15 in the driving assembly.

[0050] In summary, according to the knob-type visual electronic password padlock of the embodiment of the present invention, when the user unlocks the lock, the password is input by rotating the knob, the knob rotates to drive the fork to rotate, the fork toggles the trigger circuit on the circuit board, the trigger circuit generates an ascending or descending signal, the circuit board makes the display component display numbers in ascending or descending order according to the ascending or descending signal, the user can observe the numbers displayed by the display component through the display lens on the observation window, when the unlock password input is completed, the circuit board outputs the corresponding unlock signal to the drive component, the drive component operates, so that the lock beam and the drive component are changed from the buckled connection state to the disengaged state, the user pulls down the lock body to complete the unlocking. Therefore, the knob-type visual electronic password padlock can improve the service life and protection ability of the product, and the structure is simple.
