[0059] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0060] Example 1:

[0061] like Figures 1-9 As shown, the password reset module in this embodiment is applied to a mechanical combination lock. The mechanical combination lock can be unlocked with the correct password and a matching mechanical key. During normal use, the user can unlock the lock by entering the correct password, eliminating the cumbersome steps of using a key and avoiding the hassle of forgetting the key. If the user forgets the password, the mechanical key can be used to unlock the lock, preventing situations where the user cannot unlock the lock due to a forgotten password. Simultaneously, the mechanical key can be used to reset the password of the mechanical combination lock for user convenience. Generally, this mechanical key serves as an emergency key and is managed by the administrator.

[0062] The combination lock reset module of this embodiment mainly includes: a mounting base 1, a lock cylinder 2, a sliding bracket 3, a combination wheel assembly 4, a toggle bracket 5, and a clutch fork 6. The mounting base 1 is rotatably mounted in the combination lock. The lock cylinder 2 is rotatably mounted on the mounting base 1 and can be driven by a mechanical key. The sliding bracket 3 is slidably mounted on the mounting base 1 and connected to the lock cylinder 2; when the lock cylinder 2 rotates, it drives the sliding bracket 3 to slide. The combination wheel assembly 4 is rotatably mounted in the combination lock and includes multiple combination wheels 40 and multiple character wheel cores 41. The multiple combination wheels 40 and multiple character wheel cores 41 are disengaged. When the combination wheels 40 and character wheel cores 41 are coupled, rotating the combination wheels 40 will drive the character wheel cores 41 to rotate; when the combination wheels 40 and character wheel cores 41 are separated, rotating the combination wheels 40 will not drive the character wheel cores 41. A toggle bracket 5 is rotatably mounted in the combination lock, and the toggle bracket 5 has a first toggle part 51 and a second toggle part 52. When the combination wheel 40 and the number wheel core 41 are separated, the combination wheel 40 and the number wheel core 41 can be actuated by the first toggle part 51 and the second toggle part 52 respectively. A clutch fork 6 is movably mounted in the combination lock and is used to separate the combination wheel 40 and the number wheel core 41. A first inclined surface 301 is provided on the sliding bracket 3, and a second inclined surface 601 is provided on the clutch fork 6. When the mechanical key is inserted into the lock cylinder 2 and drives the sliding bracket 3 to slide, the first inclined surface 301 pushes against the second inclined surface 601, causing the toggle bracket 5 to separate the combination wheel 40 and the number wheel core 41.

[0063] In this embodiment, a first inclined surface 301 is provided on the sliding bracket 3, and a second inclined surface 601 is provided on the clutch fork 6. Preferably, the first inclined surface 301 and the second inclined surface 601 have the same inclination direction and inclination angle. When the mechanical key is inserted into the lock cylinder 2 to unlock, the lock cylinder 2 rotates, causing the sliding bracket 3 to slide, and the first inclined surface 301 pushes against the second inclined surface 601, so that the lever 5 separates and decouples the combination wheel 40 and the number wheel core 41, facilitating the subsequent combination reset operation. That is, in this embodiment, when the mechanical key unlocks, the combination wheel 40 and the number wheel core 41 can be automatically separated, and the user does not need to press the clutch fork 6 by hand, making the operation simple and the combination reset operation simple.

[0064] Specifically, such as Figures 3-4As shown, in this embodiment, the sliding bracket 3 has a protrusion 30 protruding towards the clutch fork 6. The cross-section of the protrusion 30 is triangular, and a first inclined surface 301 is provided on the protrusion 30. The clutch fork 6 has an opening groove 60 corresponding to the protrusion 30. This opening groove 60 is trapezoidal, and a second inclined surface 601 is provided in the opening groove 60, with the protrusion 30 located within it. During actual operation, the sliding bracket 3 slides longitudinally, and the first inclined surface 301 on the protrusion 30 pushes against the second inclined surface 601 on the opening groove 60, causing the clutch fork 6 to move laterally. The direction of the lateral movement of the clutch fork 6 is perpendicular to the sliding direction of the sliding bracket 3. This lateral movement of the clutch fork 6 simultaneously pushes all the character wheel cores 41, causing all the character wheel cores 41 to separate and decouple from their corresponding password wheels 40, thus simplifying the password reset process.

[0065] Furthermore, it is called an opening groove 60 because the opening groove 60 has an opening on one side, and the protrusion 30 can slide into the opening groove 60 along the side opening for easy assembly. The protrusion 30 can also disengage from the opening groove 60 along the side opening. In actual use, the sliding bracket 3 of this embodiment is provided with a protrusion 30, the first inclined surface 301 is located on the protrusion 30, the clutch fork 6 is provided with an opening groove 60 corresponding to the protrusion 30, and the second inclined surface 601 is located at the opening groove 60. Manufacturing and processing are simple, and the two slide smoothly together.

[0066] It should be explained that the sliding bracket 3 of this embodiment is provided with a protrusion 30, and the clutch fork 6 is provided with an opening groove 60. The protrusion 30 and the opening groove 60 are movably engaged, and the first inclined surface 301 and the second inclined surface 601 are movably abutted. This part of the structure can be distinguished from the lock disclosed in publication number EP2942457B1. The existence of this distinguishing feature means that when the password reset module of this embodiment performs a password reset, the lock cylinder 2 drives the sliding bracket 3, the sliding bracket 3 drives the clutch fork 6, and thus the digit wheel core 41 and the password wheel 40 are automatically disengaged, without the need for the user to perform any other pressing operations.

[0067] Compared to the structure disclosed in EP2942457B1, the password reset module in this embodiment differs from the one described above in its password reset driver structure. Otherwise, the other structures in this embodiment are essentially the same as those disclosed in EP2942457B1. The differences are detailed below, specifically the driver-related structures of the password reset module.

[0068] like Figure 2 , Figures 5-6 as well as Figure 9As shown, in this embodiment, the actuating bracket 5 is rotatably mounted in the combination lock, specifically, the actuating bracket 5 is rotatably mounted in the combination lock via a central shaft. The actuating bracket 5 abuts against a torsion spring 7, and the torque of the torsion spring 7 drives the actuating bracket 5 to rotate. When the first actuating part 51 and the second actuating part 52 of the actuating bracket 5 are aligned with the combination wheel 40 and the character wheel core 41 respectively, the rotation of the actuating bracket 5 causes the first actuating part 51 and the second actuating part 52 to actuate the combination wheel 40 and the character wheel core 41 respectively, thus resetting the combination. A rolling column 10 is movably mounted on the mounting base 1. The rolling column 10 is preferably a copper column. The torsion spring 7 abuts against both the rolling column 10 and the actuating bracket 5; that is, one torsion arm of the torsion spring 7 abuts against the rolling column 10, and the other torsion arm abuts against the actuating bracket 5. The rolling column 10 can move up and down, compressing the torsion spring 7 to drive the actuating bracket 5. When the rolling column 10 presses down, the torsion spring 7 is compressed, driving the actuating bracket to rotate.

[0069] In actual use, when the combination wheel 40 and the character wheel core 41 are separated, the mounting base 1 rotates, and the abutment part 80 on the lock seat 8 drives the rolling column 10 to move up and down, thereby compressing the torsion spring 7 and causing the actuating bracket 5 to rotate. The actuating bracket 5 actuates the combination wheel 40 and the character wheel core 41 through the first actuating part 51 and the second actuating part 52 respectively to reset the combination. The structure is simple.

[0070] Furthermore, such as Figures 7-8 As shown, the combination lock includes a lock base 8. During use, the mechanical combination lock can be fixed to the door through the lock base 8. A mounting base 1 is rotatably mounted on the lock base 8, and its end has a latch (not shown in the figure). The rotation of the mounting base 1 drives the latch to rotate, thereby locking or unlocking the door. A through groove 11 is provided on the mounting base 1, and a rolling pin 10 is movably disposed in the through groove 11. An abutment part 80 is provided on the lock base 8. When the mounting base 1 rotates relative to the lock base 8, the abutment part 80 forces the rolling pin 10 to move up and down. Specifically, in this embodiment, the abutment part 80 is set as an arc-shaped groove, and the depth at both ends of the arc-shaped groove is less than the depth in the middle. That is, the recessed depth in the middle of the arc-shaped groove is deeper, and the recessed depth at both ends is shallower. When the middle of the arc-shaped groove abuts against the rolling pin 10, the rolling pin 10 will not be pressed down. When the two ends of the arc-shaped groove abut against the rolling column 10, the rolling column 10 is pressed down, causing the torsion spring 7 to deform. The elastic force of the torsion spring 7 acts on the rotating bracket, causing the rotating bracket to rotate.

[0071] More specifically, in this embodiment, the code wheel 40 is provided with a first cam 401, and the character wheel core 41 is provided with a second cam 411. The outer walls of both the first cam 401 and the second cam 411 include two opposing spiral surfaces 420, that is, two symmetrically arranged opposing spiral surfaces 420 forming a heart shape. The junction of the two opposing spiral surfaces 420 forms a recess 421. The first actuating part 51 and the second actuating part 52 can respectively abut against the recess 421 of the first cam 401 and the recess 421 of the second cam 411, so that the code wheel 40 and the character wheel core 41 are reset, thus resetting the code. In this embodiment, the code wheel 40 and the character wheel core 41, the first cam 401 on the code wheel 40, the second cam 411 on the character wheel core 41, and the first actuating part 51 and the second actuating part 52 on the actuating bracket 5 are all the same structure as those disclosed in EP2942457B1, which are prior art and will not be described in detail here.

[0072] When a password reset is required, the user inserts the mechanical key matching the lock cylinder 2 into the lock cylinder 2 and turns the lock cylinder 2 to unlock it. The lock cylinder 2 drives the sliding bracket 3 to slide closer to the lock cylinder 2. The sliding bracket 3 pushes against the second inclined surface 601 on the clutch fork 6 through the first inclined surface 301, causing the clutch fork 6 to move laterally. During the lateral movement of the clutch fork 6, all the number wheel cores 41 are actuated, so that all the number wheel cores 41 are discoupled from their corresponding password wheels 40. At this time, the first cam 401 on the password wheel 40 is aligned with the first actuating part 51 on the actuating bracket 5, and the second cam 411 on the number wheel core 41 is aligned with the second actuating part 52 on the actuating bracket 5. The user rotates the mounting base 1 (generally by rotating the outer casing 9). The rolling column 10, under the action of the contact part 80 (i.e., the deep and shallow groove), compresses the torsion spring 7 downwards. The torsion spring 7 drives the actuating bracket 5 to rotate. The actuating bracket 5, through the first actuating part 51 and the second actuating part 52, respectively drives the first cam 401 and the second cam 411 to rotate (i.e., the code wheel 40 and the character wheel core 41 rotate), until the first actuating part 51 abuts against the recess 421 of the two helical surfaces 420 on the first cam 401, and the second actuating part 52 abuts against the groove of the two helical surfaces 420 on the second cam 411. At this point, the code wheel 40 and the character wheel core 41 stop rotating, and the code reset is complete. A spring is provided at the end of the clutch fork 6. The spring force allows the clutch fork 6 to reset all the character wheel cores 41, re-coupling them with the code wheel 40.

[0073] Example 2:

[0074] like Figures 10-12 As shown, and in conjunction with the specific structure of the password reset module described in Embodiment 1, the mechanical combination lock of this embodiment mainly includes:

[0075] Lock base 8, the lock base 8 is provided with a lock groove;

[0076] The outer casing 9 is rotatably mounted on the lock base 8;

[0077] In the password reset module of Embodiment 1, the mounting base 1 is fixedly connected to the outer shell 9, and a locking member 31 is provided on the sliding bracket 3. The locking member 31 is rotatably mounted on the sliding bracket 3 and moves against the clutch fork 6.

[0078] Compared to the lock disclosed in EP2942457B1, the structural difference of the mechanical combination lock in this embodiment lies in the password reset module in Embodiment 1. Specifically, as described in Embodiment 1, a protrusion 30 is provided on the sliding bracket 3, and an opening groove 60 is provided on the clutch fork 6. The protrusion 30 and the opening groove 60 are movably engaged, and the first inclined surface 301 and the second inclined surface 601 are movably abutted. Furthermore, the drive-related structure of the password reset module is as follows: a rolling column 10 is movably provided on the mounting base 1. This rolling column 10 is preferably a copper column. A torsion spring 7 abuts against both the rolling column 10 and the actuating bracket 5. The rolling column 10 can move up and down, compressing the torsion spring 7 to drive the actuating bracket 5. When the rolling column 10 is pressed down, the torsion spring 7 is compressed, driving the rotating bracket to rotate. Apart from this, the other structures are basically the same and are existing technology, so they will not be described in detail here.

[0079] In this solution, the password reset module of the mechanical combination lock is simple to operate and has a simple structure.
