Description

Technical Field

[0001] The present invention relates to the technical field of electronic padlocks, and in particular to a knob-type visual electronic password padlock. Background Art

[0002] The current rotary combination padlock is purely mechanical and cannot be opened or managed electronically. If the fixed combination is forgotten, it can only be broken into. When the lock is not used for a long time, it is very easy to forget the combination, causing inconvenience to the user.

[0003] At the same time, although there are some electronic padlocks on the market that use keyboards and arrow keys to enter passwords, this series of padlocks has extremely poor security protection. The password input buttons divide the lock surface into several small areas. At the same time, the buttons are made of plastic materials and are extremely easy to damage, resulting in a short service life. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the first object of the present invention is to provide a knob-type visual electronic combination padlock that can improve the product's service life and protection capabilities and has a simple structure.

[0005] To achieve the above-mentioned purpose, the first embodiment of the present invention proposes a knob-type visual electronic password padlock, comprising: a lock beam; a lock body, wherein the lock body comprises: a lock shell, a mounting seat, a password input component, a display component, a drive component and a power supply component; the drive component is arranged in the lock shell, one end of the drive component 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 component; the password input component comprises: a knob, a limiter, a shift fork and a circuit board; the knob is arranged on the outer surface of the lock shell, and passes through the lock shell and the limiter.

[0027] The following describes embodiments of the present invention in detail, 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 are not to be construed as limiting the present invention.

[0028] The following describes a knob-type visual electronic combination 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 base 10, a password input component, a display component, a drive component and a power supply component.

[0031] The drive assembly is housed within the lock housing 4. One end of the drive assembly is connected to a locking beam 19. The upper portion of the locking beam 19 extends above the lock body, and both ends of the locking beam 19 are movably engaged with the drive assembly. When the locking beam 19 and the drive assembly are engaged, the lock is complete. It should be noted that arcuate grooves are provided on the lower sides of the locking beam 19 on both sides facing each other. These arcuate grooves engage with the drive assembly to secure the locking beam 19 to the lock body.

[0032] Furthermore, if Figure 1 As shown, the password input assembly includes a knob 2, a stopper 5, a shift fork 8, and a circuit board 9. The knob 2 is mounted on the outer surface of the lock housing 4 and extends through the lock housing 4 and is riveted to the stopper 5. The shift fork 8 is sleeved onto the stopper 5 and engages with the trigger circuit on the circuit board 9. The circuit board 9 is electrically connected to the drive assembly and fixedly connected to the mounting base 10. The display assembly is mounted on the circuit board 9. When the knob 2 is rotated, the shift fork 8 activates the trigger circuit, causing the display assembly to display a number. The lock housing 4 is provided with an observation window, positioned opposite the display assembly, and a display lens 3 is mounted on the observation window.

[0033] Specifically, the user can pre-set the unlocking password. When the user unlocks the door, they input the password by rotating the knob 2. The rotation of the knob 2 drives the shift fork 8, which shifts the trigger circuit on the circuit board 9. The trigger circuit generates an ascending or descending signal. The circuit board 9 causes the display component to 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. When the unlocking password is entered, the circuit board 9 outputs the corresponding unlocking signal to the drive component. The drive component operates, causing the lock beam 19 and the drive component to change from a buckled connection state to a 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 provided on the mounting base 10, and the power supply assembly is electrically connected to the driving assembly and the circuit board 9. 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 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 on 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 the root of one tooth 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 disconnects after contacting the long contact piece 92 to generate an ascending signal, and the other short contact piece 91 disconnects after contacting the long contact piece 92 to generate a descending signal. For example, 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 pick 7 , one end of which is connected to the lock housing 4 , and the other end of which is engaged with the other tooth root of the shift fork 8 .

[0039] Specifically, if Figure 2 As shown, the other end of the elastic pick 7 engages with the other tooth root of the shift fork 8, which is two teeth away from the tooth root that engages with the long contact piece 92. When the knob 2 is turned, the shift fork 8 rotates, and the top of the tooth of the shift fork 8 forces the elastic pick 7 to deform. When the tooth passes the top of the elastic pick 7, the elastic pick 7 forces the shift fork 8 to engage again, realizing the 10-point positioning function of the shift fork 8.

[0040] According to one embodiment of the present invention, Figure 1 As shown, the password input component further 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 a password, they observe the number displayed on the display assembly through the display lens 3 at the observation window. If 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, thus completing the password entry. The confirmation button 1 can be used to complete the entry of multiple passwords, for example, clicking to confirm each password digit.

[0042] According to one embodiment of the present invention, Figure 4 As shown, the drive assembly includes: a motor 11, which is a hollow cup motor 11. The motor 11 is mounted on the mounting base 10 and is electrically connected to the circuit board 9; a bracket 12, which is arranged on the periphery of the motor 11; a torsion spring 13, which is sleeved on one side of the bracket 12, and one end of the torsion spring 13 is stuck on the periphery of the motor 11; a transmission block 14, which is sleeved on the output shaft of the motor 11, and 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 relatively large, which makes the motor work for about 1 second when unlocking this series of locks; and the cost of variable speed motors is relatively high, the structure of reduction motors is complex, and the failure rate of the gearbox thereon is relatively high, which makes the cost of the locks high and the user experience poor. The motor 11 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 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.

[0044] Furthermore, if Figure 4 As shown, when the rotary electronic combination padlock is in the 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 turned 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 drive 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 lock tongues 16, the two lock tongues 16 are arranged opposite to each other, and a compression spring 18 is provided between the two lock tongues 16, and two cylinders are provided on the lock 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. 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 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 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. 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 is changed from the locked state to the 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 is reversed 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 the 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 left 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 via 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 is also used to block the drive assembly. Figure 1 As shown, the block 17 can block the limit block 15 in the drive assembly.

[0050] In summary, according to the embodiment of the present invention, when the user unlocks the lock, they input the password by rotating the knob. The rotation of the knob drives the shift fork to rotate, and the shift fork toggles the trigger circuit on the circuit board. The trigger circuit generates an ascending or descending signal. The circuit board causes the display component to 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 unlocking password is entered, the circuit board outputs the corresponding unlocking signal to the drive component. The drive component operates, causing the lock beam and the drive component to change from a buckled connection state to a disengaged state. The user pulls down the lock body to complete the unlocking. Therefore, the knob-type visual electronic password padlock can improve the product's service life and protection capabilities, and has a simple structure.
