[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0022] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0023] To address the technical problems of large size and inconvenient unlocking in existing front locks, this application provides a front lock that is easy to unlock and reduces size. The front lock 1 can be applied to door locks, such as... Figure 1 As shown, the door lock includes a front lock 1, a rear lock 2, and a bolt 3. The front lock 1 is installed on the outside of the door, the rear lock 2 is installed on the inside of the door, and the bolt 3 is installed on the door. The front lock 1 and the rear lock 2 are connected to the bolt 3 via locking rods 4, so that the bolts 4 can move the latch of the bolt 3 to unlock the door.

[0024] It should be noted that in some embodiments, the door lock may not include the rear lock 2.

[0025] Firstly, Figures 2 to 13 A front lock 1 provided in this application embodiment includes an assembly shell 10, a mechanical and electronic unlocking structure, a keyboard module 171, a fingerprint module 172, and a control board 18. The assembly shell 10 has an assembly cavity; the assembly cavity is provided with an installation wall 112 to divide the assembly cavity into a first chamber 111a and a second chamber 111b; the second chamber 111b is open; the assembly shell 10 is also provided with a fingerprint mounting hole 10a, which communicates with the first chamber 111a. The electromechanical unlocking structure includes a mechanical lock cylinder 12 passing through the mounting wall 112, an electric drive device 13 located in the first chamber 111a, and a clutch assembly 14, wherein the clutch assembly 14 is connected to the electric drive device 13; the clutch assembly 14 is provided with a push plate 142; one end of the mechanical lock cylinder 12 located in the first chamber 111a is provided with a movable telescopic rod 124; the telescopic rod 124 is provided corresponding to the push plate 142; The keyboard module 171 is located in the second chamber 111b and is fitted onto the mechanical lock cylinder 12; The fingerprint module 172 is installed in the fingerprint mounting hole 10a; The control board 18 is located in the second chamber 111b and between the keyboard module 171 and the mounting wall 112; the keyboard module 171, the electric drive device 13 and the fingerprint module 172 are electrically connected to the control board 18 respectively.

[0026] Understandably, the fingerprint module 172 is located on the periphery of the assembly shell 10, facilitating fingerprint unlocking for the user. The keypad module 171 is located in the second chamber 111b, facing the user for password unlocking. The mechanical lock cylinder 12 passes through the keypad module 171, allowing the user to easily insert and turn the key for mechanical unlocking. The keypad module 171 and fingerprint module 172 are connected to the electric drive unit 13 via the control board 18. The electric drive unit 13 controls the clutch assembly 14, which locks the locking rod 4 structure, which can then unlock the latch 3. Furthermore, the telescopic rod 124 of the mechanical lock cylinder 12 can drive the clutch assembly 14 by pushing the push plate 142. Thus, the mechanical lock cylinder 12 and the electric drive unit 13 share the same clutch assembly 14, reducing the number of components within the assembly cavity and consequently reducing space requirements. Furthermore, this application divides the assembly cavity into a first chamber 111a and a second chamber 111b by mounting wall 112. The second chamber 111b accommodates the keyboard module 171 and control board 18. The electric drive device 13, clutch assembly 14, and telescopic rod 124 are all enclosed in the first chamber 111a. Damaging the components in the second chamber 111b will not achieve the purpose of unlocking, thus serving the purpose of anti-pry and protection, and also has a certain waterproof effect.

[0027] Among them, the front lock 1 locks and unlocks the locking rod 4 through a mechanical and electronic unlocking structure. After the locking rod 4 is locked, the front lock 1 can drive the locking rod 4 to rotate, thereby driving the bolt of the latch 3 to move to unlock.

[0028] like Figure 3 As shown, in some embodiments, the mechanical lock cylinder 12 is positioned at the center of the assembly housing 10, and the axis of the mechanical lock overlaps with the axis of the assembly housing 10. In this embodiment, the numbers on the keyboard module 171 can be designed to surround the mechanical lock cylinder 12, thus achieving both a reasonable layout and an aesthetically pleasing effect.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, the assembly housing 10 includes a housing wall 111, a pivot seat 101, a mounting plate 16, a locking shaft 102, and a locking plate 15. The housing wall 111 is cylindrical; the mounting wall 112 is disposed inside the housing wall 111; the pivot seat 101 is connected to the end of the housing wall 111 away from the keyboard module 171; the mounting plate 16 is connected to the side of the pivot seat 101 facing the housing wall 111, and together with the pivot seat 101, forms a locking cavity; the locking shaft 102 passes through the pivot seat 101 and extends toward the side away from the mounting plate 16; the locking plate 15 is located in the locking cavity and is sleeved on the locking shaft 102. The locking shaft 102 is used to connect the locking lever 4.

[0030] Understandably, the structure formed by the connection of the pivot seat 101 and the mounting plate 16 seals the end of the first chamber 111a away from the second chamber 111b, thereby sealing the first chamber 111a. The pivot seat 101 also provides a mounting position for the locking shaft 102. When the locking plate 15 is locked by the clutch assembly 14, rotating the assembly housing 10 can drive the pivot seat 101, the mounting plate 16, and the locking plate 15 to rotate synchronously, thereby driving the locking shaft 102 to rotate, so as to drive the locking rod 4 to rotate and drive the latch 3 to actuate and unlock.

[0031] like Figure 5 As shown, in some embodiments, the clutch assembly 14 includes a clutch bracket 141 and a clutch pin 143, with the clutch pin 143 disposed on the clutch bracket 141; a push plate 142 is disposed on the clutch bracket 141 and extends in a direction away from the clutch bracket 141; a locking plate 15 has a first positioning hole 15a, and a mounting plate 16 has a second positioning hole 16a, the second positioning hole 16a corresponding to the clutch pin 143, and the first positioning hole 15a corresponding to the second positioning hole 16a; wherein, the telescopic rod 124 is movable to abut against the push plate 142 and pushes the push plate 142, thereby driving the clutch bracket 141 to move the clutch pin 143 to insert into the first positioning hole 15a. When unlocking is required, the clutch pin 143 moves to insert into the first positioning hole 15a under the action of the electromechanical unlocking structure to lock the locking rod 4. At this time, the user only needs to rotate the assembly housing 10 to rotate the locking rod 4 and thus unlock. When the clutch pin 143 is not inserted into the first positioning hole 15a, even if the user rotates the assembly housing 10, the locking rod 4 cannot be rotated, and the lock cannot be unlocked.

[0032] Thus, both mechanical and electronic unlocking are achieved using the same clutch assembly 14. When electronic unlocking (e.g., fingerprint or password unlocking) is performed, the electric drive device 13 is activated to drive the clutch bracket 141, which in turn moves the clutch pin 143. When mechanical unlocking is performed, the telescopic rod 124 on the mechanical lock cylinder 12 moves away from the mechanical lock cylinder 12, abutting against the push plate 142 and pushing it to move. The movement of the push plate 142 drives the clutch bracket 141, which in turn moves the clutch pin 143. This application achieves two unlocking methods by sharing the clutch assembly 14, reducing the number of components and thus the space required.

[0033] During electronic unlocking, after the user input information is successfully paired with the non-mechanical lock (e.g., fingerprint module 172 and keyboard module 171), the non-mechanical lock controls the electric drive device 13 to start via the control board 18. After the electric drive device 13 is started, it can drive the clutch pin 143 to move.

[0034] When unlocking is achieved mechanically, the user can insert the key into the keyhole 123a of the mechanical lock cylinder 12. After the mechanical lock cylinder 12 and the key are successfully matched, the key can be used to drive the telescopic rod 124 to move, thereby activating the clutch pin 143.

[0035] like Figures 1 to 4 As shown, in some embodiments, a fixed base 103 is also included, which is movably sleeved on the locking shaft 102. The fixed base 103 is used to connect with the door body, and the assembly can rotate relative to the fixed base 103.

[0036] refer to Figure 2 It also includes a front torsion spring 104, which is disposed on the side of the fixed base 103 away from the assembly housing 10. The front torsion spring 104 can drive the front lock 1 to reset.

[0037] refer to Figure 3 and Figure 4 The assembly housing 10 is also provided with an interface hole that communicates with the second chamber 111b. The control board 18 is provided with a USB interface, the interface hole is set with respect to the USB interface, and a removable cover 105 is provided at the interface hole.

[0038] like Figure 5 As shown, in some embodiments, the axial direction of the telescopic rod 124 is parallel to the axial direction of the clutch pin 143. This ensures that the clutch pin 143 can move smoothly into the first positioning hole 15a.

[0039] like Figure 6 and Figure 7 As shown, in some embodiments, the clutch assembly 14 further includes a first elastic element 144. One end of the clutch pin 143 is inserted into the clutch bracket 141, and both ends of the first elastic element 144 are respectively connected to the clutch pin 143 and the clutch bracket 141. When the clutch bracket 141 moves, the first elastic element 144 drives the clutch pin 143 to move. It is understood that when the clutch bracket 141 is moved by the electric drive device 13 or the push plate 142, the clutch bracket 141 can compress the first elastic element 144. When the first elastic element 144 is compressed to a certain extent, the accumulated elastic force will push the clutch pin 143 to move. Thus, the first elastic element 144 can transmit force and also act as a buffer.

[0040] In this embodiment, the first elastic element 144 is a spring.

[0041] like Figure 6 and Figure 7As shown, in some embodiments, the clutch assembly 14 further includes a second elastic element 145. The output end of the electric drive device 13 is provided with a drive rod 131, which is rotatably inserted into the clutch frame 141. The peripheral wall of the clutch frame 141 is provided with a helical protrusion 1311. The two ends of the second elastic element 145 are respectively connected to the clutch frame 141 and the helical protrusion 1311. When the drive rod 131 rotates, it drives the second elastic element 145 to move the clutch frame 141 through the helical protrusion 1311.

[0042] It is understandable that when the electric drive device 13 is started, it can drive the drive rod 131 to rotate. When the drive rod 131 rotates, it drives the spiral protrusion 1311 to rotate. When the spiral protrusion 1311 rotates, it will stretch the second elastic element 145. When the second elastic element 145 is stretched to a certain extent, the accumulated elastic force will drive the clutch frame 141 to move. In this way, the second elastic element 145 can play the role of transmitting force, and the second elastic element 145 can also play a buffering role.

[0043] In this embodiment, the second elastic element 145 is a spring.

[0044] In this embodiment, the electric drive device 13 includes a drive motor 132, a first gear 133 and a second gear 134. The output end of the drive motor 132 is connected to the first gear 133, the first gear 133 meshes with the second gear 134, and the second gear 134 is connected to the drive rod 131.

[0045] like Figure 8 As shown, in some embodiments, the clutch assembly 14 further includes a clutch housing 146, which is connected to the mounting plate 16. The isolation frame 19 is also connected to the mounting plate 16. The electric drive device 13 and the clutch assembly 14 are disposed inside the clutch housing 146. The clutch housing 146 is provided with a clutch hole 146a and a through hole 146b. The clutch hole 146a is correspondingly provided with the clutch pin 143, and the through hole 146b is correspondingly provided with the push plate 142, and the push plate 142 passes through the through hole 146b. Understandably, the clutch housing 146 serves to isolate and protect the electric drive unit 13 and the clutch assembly 14. The clutch hole 146a is designed to ensure the smooth movement of the clutch pin 143, and the through hole 146b is designed to ensure the cooperation between the push plate 142 and the mechanical lock cylinder 12.

[0046] like Figure 6 and Figure 7As shown, in some embodiments, the push plate 142 includes a connecting portion 1421, a transition portion 1422, and a pushing portion 1423. One end of the connecting portion 1421 is connected to the clutch frame 141, and the other end extends in a direction away from the clutch frame 141. One end of the transition portion 1422 is connected to the other end of the connecting portion 1421 and is set at an angle to the connecting portion 1421. One end of the pushing portion 1423 is connected to the other end of the transition portion 1422 and is set at an angle to the transition portion 1422. The pushing portion 1423 extends in a direction away from the clutch frame 141. The pushing portion 1423 is correspondingly arranged with the telescopic rod 124.

[0047] refer to Figure 3 The mechanical lock cylinder 12 is installed in the middle of the front lock housing 11. The electric drive unit 13 and the clutch assembly 14 are offset from the axis of the mechanical lock cylinder 12, that is, the electric drive unit 13 and the clutch assembly 14 are located on one side of the mechanical lock cylinder 12, and the push plate 142 is provided on the side of the clutch assembly 14 facing the mechanical lock cylinder 12. In this embodiment, the push plate 142 is provided on the side of the clutch bracket 141 facing the mechanical lock cylinder 12. In this way, the axial dimension of the front lock 1 can be reduced. In some embodiments, refer to Figure 5 and Figure 6 By designing the push plate 142 to include a connecting part 1421, a transition part 1422 and a pushing part 1423, the axial dimension of the front lock 1 can be reduced, and a reasonable layout space can be achieved.

[0048] like Figure 6 and Figure 7 As shown, in some embodiments, the connecting portion 1421 has a reinforcing rib 1424 on the side facing the transition portion 1422, and the two ends of the reinforcing rib 1424 extend to connect the clutch frame 141 and the transition portion 1422 respectively. In this way, the strength of the push plate 142 can be improved.

[0049] like Figure 3 and Figure 5 As shown, in some embodiments, the fingerprint module 172 is located on the side of the mechanical lock cylinder 12 opposite to the clutch assembly 14. Thus, when the front lock 1 is installed on the door, the electric drive unit 13 and the clutch assembly 14 can be located on the lower side, and the fingerprint module can be located on the upper side, facilitating fingerprint unlocking. Furthermore, the electric drive unit 13 and the clutch assembly 14 have a certain weight, and their lower location avoids affecting the mechanical lock cylinder.

[0050] like Figure 3 and Figure 4As shown, in some embodiments, the front lock further includes an isolation frame 19, which is disposed within the first chamber 111a. The isolation frame 19 has an isolation hole with a through hole, which corresponds to the push plate 142. The push plate 142 passes through the through hole and is inserted into the isolation hole. One end of the mechanical lock cylinder 12 located in the first chamber 111a is inserted into the isolation hole, so that the telescopic rod 124 is positioned corresponding to the push plate 142. It can be understood that the isolation frame 19 provides isolation and protection for the push plate 142 and the telescopic rod 124.

[0051] refer to Figure 12 The mounting wall 112 is provided with a mounting hole 11a, and the wall of the mounting hole 11a is provided with a clearance groove 11b; Reference Figure 11 and Figure 13 The outer wall surface of the mechanical lock cylinder 12 is provided with a fixing structure 121, which is used to engage with the mounting wall 112. In this embodiment, the fixing structure 121 is provided with a fixing groove 121a; the mechanical lock cylinder 12 passes through the mounting hole 11a, and the mechanical lock cylinder 12 and the mounting wall 112 have an unlocked state and a locked state; wherein, in the unlocked state, the fixing structure 121 corresponds to the clearance groove 11b, so that the fixing structure 121 can pass through the clearance groove 11b; Reference Figure 9 , Figure 10 and Figure 11 In the locked state, the fixing structure 121 and the clearance groove 11b are misaligned, and the mounting wall 112 is locked in the fixing groove 121a.

[0052] In this embodiment, by providing an abutment groove 11b, the fixing structure 121 on the mechanical lock cylinder 12 can easily pass through, facilitating the assembly and disassembly of the mechanical lock cylinder 12 and the mounting wall 112 in the unlocked state. When it is necessary to assemble the mechanical lock cylinder 12 and the mounting wall 112, simply adjust the fixing structure 121 on the mechanical lock cylinder 12 until it engages with the mounting wall 112 to lock the mechanical lock cylinder 12 and complete the assembly. This application enables convenient assembly and disassembly of the mechanical lock cylinder 12 and the mounting wall 112. Specifically, when the mounting wall 112 is engaged with the fixing groove 121a of the fixing structure 121, the mechanical lock cylinder 12 is assembled in place, achieving a stable connection between the mounting wall 112 and the mechanical lock cylinder 12.

[0053] refer to Figure 9 , Figure 10 and Figure 12 In this embodiment, the mechanical lock cylinder 12 and the mounting wall 112 rotate relative to each other, thereby enabling the switching between the unlocked state and the locked state.

[0054] like Figure 9 , Figure 10 , Figure 11and Figure 13 As shown, in some embodiments, the fixing structure 121 includes a first boss 1211 and a second boss 1212, which are spaced apart along the axial direction of the mechanical lock cylinder 12 on the outer wall surface of the mechanical lock cylinder 12 to form a fixing groove 121a. This structure is simple and easy to assemble.

[0055] like Figure 11 and Figure 13 As shown, in some embodiments, the height of the first protrusion 1211 is lower than the height of the second protrusion 1212; wherein, in the unlocked state, the first protrusion 1211 can pass through the clearance groove 11b, while the second protrusion 1212 cannot pass through the clearance groove 11b. This ensures unidirectional assembly of the mechanical lock cylinder 12 during assembly. The second protrusion 1212 acts as a limit; when the mechanical lock cylinder 12 is inserted into the mounting hole 11a until the second protrusion 1212 is blocked and cannot be further inserted, it indicates that the mechanical lock cylinder 12 is in the correct insertion position. The mechanical lock cylinder 12 or the mounting shell 10 can then be rotated to lock the mechanical lock cylinder 12 and the front lock shell 11.

[0056] In some embodiments, the first boss 1211 and the second boss 1212 extend along the radial direction of the mechanical lock cylinder 12, and the mounting wall 112 is perpendicular to the axial direction of the housing wall 111. Thus, switching between the unlocked state and the locked state can be achieved simply by rotating the mechanical lock cylinder 12.

[0057] In this embodiment, the shell wall 111 is cylindrical; in other embodiments, the shell wall 111 may also be non-cylindrical.

[0058] like Figure 12 As shown, in some embodiments, the portion of the mounting wall 112 that is fastened within the fixing groove 121a is defined as the fastening portion 1121, and the portion of the fastening portion 1121 near the clearance groove 11b is provided with an inclined surface 1122.

[0059] It is understandable that by setting the inclined surface 1122, the part of the clamping part 1121 that is close to the avoidance groove 11b can be prevented from blocking the fixing structure 121 during rotation, so that the fixing structure 121 can rotate smoothly to the clamping part 1121 and be clamped to the clamping part 1121.

[0060] In this embodiment, the clamping part 1121 near the avoidance groove 11b is provided with an inclined surface 1122 on the side facing the first chamber 111a and the side facing the second chamber 111b.

[0061] like Figure 9 and Figure 12As shown, in some embodiments, at least one side of the mounting wall 112 is provided with a limiting stop 1123; the locking part 1121 is located between the limiting stop 1123 and the clearance groove 11b. Thus, during the process of the mechanical lock cylinder 12 rotating to the locked state, the limiting stop 1123 can play a limiting role.

[0062] like Figure 9 , Figure 11 and Figure 12 As shown, in some embodiments, the mounting wall 112 is also provided with a locking hole 11c, and a locking rod 1124 is detachably provided in the locking hole 11c; in the locked state, the locking rod 1124 passes through the locking hole 11c and is located on the side of the fixing structure 121 facing the avoidance groove 11b.

[0063] Understandably, after the mechanical lock cylinder 12 is rotated to the locked state, the locking rod 1124 can be fitted into the locking hole 11c. This confines the mechanical lock cylinder 12 between the locking rod 1124 and the limiting stop 1123, improving the positional stability of the mechanical lock cylinder 12 in the locked state and preventing the mechanical lock cylinder 12 from loosening. At the same time, the end of the locking rod 1124 pressing against the second boss also serves to lock the outer cylinder to the mounting wall 112.

[0064] like Figure 11 and Figure 13 As shown, in some embodiments, the mechanical lock cylinder 12 includes an outer cylinder 122 and an inner lock cylinder 123. The outer wall of the outer cylinder 122 is provided with a fixing structure 121; the inner lock cylinder 123 is rotatably inserted into the outer cylinder 122 and is provided with a keyhole 123a.

[0065] It is understandable that when the mechanical lock cylinder 12 is rotated to the locked state, the outer cylinder 122 is locked and fixed to the mounting wall 112. When unlocking with a key, the key can be inserted into the keyhole 123a, and the inner lock cylinder 123 can be rotated by the key.

[0066] It should be noted that the keyhole 123a of the inner lock cylinder 123 of the mechanical lock cylinder 12 is also equipped with a pin. The pin is a key component inside the mechanical lock cylinder 12 used to control the movement of the inner lock cylinder 123. The unlocking function is achieved by matching the key with the pins of different heights. The setting of the pin can adopt existing technology, which will not be described in detail here.

[0067] like Figure 11 and Figure 13 As shown, in some embodiments, the inner lock cylinder 123 has a telescopic groove 123b on the side opposite to the insertion end of the keyhole 123a, and a telescopic rod 124 is provided in the telescopic groove 123b; a mating rod 125 is provided on the peripheral wall of the telescopic rod 124; a spiral groove 123c is provided on the peripheral wall of the inner lock cylinder 123; and the mating rod 125 is movably inserted into the spiral groove 123c. When the inner lock core 123 rotates, the mating rod 125 moves along the spiral groove 123c and drives the telescopic rod 124 to move along the axial direction of the inner lock core 123, so that the telescopic rod 124 extends or retracts into the telescopic groove 123b.

[0068] Understandably, when the inner lock cylinder 123 rotates, it rotates relative to the telescopic rod 124, causing the mating rod 125 to move along the spiral groove 123c, thereby driving the telescopic rod 124 to extend or retract into the telescopic groove 123b. When the telescopic rod 124 extends out of the telescopic groove 123b, it can engage with the clutch assembly 14 inside the front lock 1, and the telescopic rod 124 drives the clutch assembly 14 to lock with the lock rod, thus unlocking the latch 3.

[0069] In some embodiments, the inner wall of the outer cylinder 122 is provided with a guide groove corresponding to the mating rod. The guide groove extends in a direction parallel to the axial direction of the outer cylinder. The end of the mating rod is inserted into the guide groove. When the inner lock core 123 rotates, the guide groove can restrict the telescopic rod 124 from rotating with the inner lock core 123, and can also guide the movement direction of the telescopic rod 124.
