[0030] The utility model discloses a specific implementation of a password lock with an electric unlocking function, see Figure 1 and Figure 2 , including a lock shell 1, a lock buckle 10 is provided on the left and right sides of the lock shell 1, and a battery compartment 52 is provided on the side of the lock shell 1. The lock shell 1 is provided with a password wheel assembly 3, a knob 2, an electric assembly 5 and a USB interface assembly 6. It should be noted that the knob 2 has a built-in lock core assembly 4. The USB interface assembly 6 is arranged on the side of the electric assembly 5, and a silicone sheet is provided on the top thereof to cover the USB interface body, which plays a role in preventing dust and foreign matter. In addition, a battery compartment 52 for powering the electric assembly 5 is placed in the battery compartment 52.
[0031] In this embodiment, the lock housing 1 includes a bottom housing 11 and a front housing 12 detachably connected to the bottom housing 11 .
[0032] Combination Figure 3 and Figure 4The lock housing 1 is provided with a lock hook 7 rotatably mounted in the lock housing 1 and a lock block 8 for limiting the rotation of the lock hook 7. A rotating shaft is passed through the middle of the lock hook 7, and the rotating shaft is fixed relative to the lock housing 1, so that the lock hook 7 can rotate relative to the lock housing 1. In order to facilitate locking, the lock hook 7 is also provided with a torsion spring that drives it to rotate in the locking direction. The lock block 8 is rotatably mounted in the lock housing 1. Specifically, a rotating shaft that can rotate relative to the lock housing 1 is formed in the middle of the lock block 8. It only needs to open a through hole on the inner bottom surface of the lock housing 1, and the rotating shaft is inserted into the through hole to realize the rotation of the lock block 8.
[0033] In this embodiment, the bottom of the lock buckle 10 extends a buckling portion 13 downward, a locking hole is opened in the middle of the buckling portion 13, the lock hook 7 is provided with a hook portion 71 buckled with the locking hole and a first limiting portion 72 arranged opposite to the hook portion 71, the end of the lock block 8 facing the first limiting portion 72 is formed with a second limiting portion 82 that abuts against the first limiting portion 72 in the height direction, and a guide column 81 is extended downward from the end of the lock block 8 opposite to the second limiting portion 82. Figure 5 The lock housing 1 is provided with a movable assembly for driving the lock block 8 to rotate, and the movable assembly includes a movable member 9 that can slide relative to the lock housing 1, and the movable member 9 is provided with a groove 91. In the assembled state, the guide post 81 is inserted into the groove 91, and the guide post 81 can slide along the groove 91. Specifically, the groove 91 is provided with two guide inclined surfaces that are mirror images of each other, and the function of the guide inclined surfaces is to resist and push the guide post 81 to move during the unlocking process.
[0034] In the locked state, the second limiting portion 82 of the lock block 8 and the first limiting portion 72 of the lock hook 7 abut against each other in the height direction, thereby limiting the rotation of the lock hook 7 and achieving locking. When unlocking, the movable member 9 moves along the length direction of the lock shell 1 under the drive of external force. Whether sliding to the left or right, the groove 91 with two guiding inclined surfaces will abut against and push the guide column 81. Under the limiting effect of the groove 91, the guide column 81 drives the lock block 8 to rotate relative to the lock shell 1, so that the second limiting portion 82 of the lock block 8 and the first limiting portion 72 of the lock hook 7 are staggered in the height direction, so that the lock block 8 releases the rotation restriction on the lock hook 7 and achieves unlocking of the lock hook 7. At this time, external force is applied to separate the lock buckle 10 from the lock hook 7 to complete the unlocking of the luggage.
[0035] Combination Figure 6In order to facilitate driving the movable part 9 to slide relative to the lock shell 1, the lock shell 1 is also provided with a knob 2 that can rotate relative to the lock shell 1. The rotation of the knob 2 can drive the movable component to slide along the lock shell 1. Specifically, the knob 2 includes a hollow knob 2 body and a rotating block 22 that is clamped at the bottom of the knob 2 body. The rotating block 22 extends a toggle portion 23 downward. The movable part 9 is provided with an unlocking groove 92. In the assembled state, the toggle portion 23 is inserted into the unlocking groove 92, and the toggle portion 23 can slide along the unlocking groove 92. It should be noted that the unlocking groove 92 is arranged in an L shape. In the locked state, the toggle portion 23 is at the corner position of the unlocking groove 92. Since the movable part 9 is restricted by the lock shell 1 and can only slide back and forth in the horizontal direction, when the knob 2 drives the toggle portion 23 to rotate, as shown Figure 6 When the body of the middle knob 2 rotates counterclockwise, the toggle portion 23 slides the longitudinal section of the unlocking slot 92 and pushes the movable member 9 to slide along the lock housing 1, thereby realizing the rotation unlocking of the knob 2 without being restricted.
[0036] Please see Figure 6 In order to unlock the lock by electric means, the lock housing 1 is also provided with an electric component 5 for driving the movable component to slide along the lock housing 1. Specifically, the electric component 5 includes a driving motor 53, and the driving motor 53 is provided with an output shaft 54. The outer peripheral side of the output shaft 54 is provided with an external thread. The outer peripheral side of the output shaft 54 is sleeved with a transmission block 55. The middle part of the transmission block 55 is provided with a threaded hole for the output shaft 54 to be inserted. The threaded hole is provided with an internal thread that meshes with the external thread. The transmission block 55 extends toward the movable component to form a pusher 56 that abuts against the movable component. Figure 5 , the movable part 9 extends upward to form a first stopper 93 and a second stopper 94 arranged at intervals. In the assembled state, the pusher 56 is located between the first stopper 93 and the second stopper 94. In the locked state, the pusher 56 abuts against the second stopper 94. When unlocking, the driving motor 53 drives the transmission block 55 to slide along the axial direction of the output shaft 54. The pusher 56 of the transmission block 55 abuts against the first stopper 93 of the movable part 9 and pushes the first stopper 93. Under the push of the transmission block 55, the first stopper 93 drives the movable part 9 to slide along the lock housing 1 in the unlocking direction, thereby realizing that the electric component 5 pushes the movable component, and the movable part 9 of the movable component slides along the lock housing 1 to release the rotation restriction of the lock block 8, thereby realizing unlocking. It should be noted that during the unlocking process, the toggle portion 23 of the rotating block 22 slides to the lateral section of the unlocking slot 92, so that the rotation restriction on the lock hook 7 can be automatically released by the electric component 5 without operating the knob 2, thereby realizing automatic unlocking. Since there is no need to rotate the knob 2 again, the operational convenience and practicality of the lock are further improved.
[0037] Combination Figure 6 and Figure 7In order to limit the rotation of the transmission block 55, a guide groove 57 is formed at the bottom of the transmission block 55, and a guide bar 14 extends from the inner bottom surface of the lock shell 1 (the inner bottom surface of the bottom shell 11) toward the guide groove 57. In the assembled state, the guide bar 14 is inserted into the guide groove 57. Under the guiding action of the guide bar 14 and the guide groove 57, the transmission block 55 can only slide along the length direction of the lock shell 1 but cannot rotate.
[0038] It should be noted that, combined with Figure 1 and Figure 2 The electric component 5 also includes a PCB board 51 fixedly installed in the lock shell 1. The PCB board 51 is electrically connected to the USB interface component 6, the drive motor 53 and the battery pack in the battery compartment 52 respectively. The PCB board 51 is provided with a trigger part 50 that penetrates the top surface of the lock shell 1. The trigger part 50 can be a fingerprint recognition module. In other embodiments, the trigger part 50 can also be other electronic function modules such as an image recognition module. The PCB board 51 can also be equipped with a Bluetooth module, a wireless signal transmission module, an infrared receiving module, etc. In this way, consumers can unlock the lock by fingerprint recognition, palm print recognition, iris recognition, Bluetooth control or infrared control of a mobile terminal, etc. The specific electric component 5 can be selectively set according to actual needs.
[0039] Combination Figure 8 and Fig. 9 The top of the rotating block 22 of the knob 2 is provided with a clutch block 43 which is inserted into the body of the knob 2 and can slide along the rotating block 22. Specifically, a slide groove 24 is provided on the top surface of the rotating block 22, and the clutch block 43 is placed in the slide groove 24, so that the clutch block 43 can slide relative to the rotating block 22. The lock housing 1 is also provided with a lock core assembly 4 and a password wheel assembly 3 for limiting the rotation of the knob 2.
[0040] The lock core assembly 4 includes a lock core body 41 built into the body of the knob 2 and located above the clutch block 43. Since the body of the knob 2 is a hollow structure, the lock core body 41 can rotate relative to the body of the knob 2. A clamping portion 42 extends from the bottom of the lock core body 41 toward the clutch block 43, and a clamping groove 432 is formed on the top surface of the clutch block 43 toward the lock core body 41.
[0041] In the locked state, the holding portion 42 is inserted into the slot 432, and the holding portion 42 abuts against the slot wall of the slot 432 in the horizontal direction to limit the clutch block 43 from sliding relative to the lock housing 1. When unlocking, insert the key and rotate the lock core body 41, the lock core body 41 drives the holding portion 42 to rotate, so that the holding portion 42 is staggered with the slot 432 in the horizontal direction, and the sliding restriction on the clutch block 43 is released. An external force is applied to rotate the knob 2 body. During the rotation of the knob 2 body, since the wheel shaft 31 of the password wheel assembly 3 cannot be telescopically moved, the wheel shaft 31 will abut the clutch block 43 to slide relative to the rotating block 22. In this way, even if the password is incorrect, the lock can still be unlocked by the key, avoiding the problem that the knob 2 body cannot be rotated due to the inability of the wheel shaft 31 to telescopically move.
[0042] In this embodiment, the password wheel assembly 3 includes a retractable axle 31, the axle 31 is located on the side of the knob 2 body, a first wedge 32 is formed at the end of the axle 31 facing the knob 2 body, a second wedge 431 is extended toward the axle 31 body to abut against the first wedge 32, and the first wedge 32 and the second wedge 431 are both formed with complementary inclined surfaces. In the locked state, the axle 31 cannot retract, the first wedge 32 abuts against the second wedge 431 to limit the rotation of the knob 2, so as to achieve locking. When unlocking, the axle 31 can retract, and an external force is applied to rotate the knob 2 body, and the knob 2 body rotates to drive the rotating block 22 to rotate. Since the clamping portion 42 of the lock core body 41 abuts against the clutch 43, the clutch 43 cannot slide relative to the rotating block 22, and the clutch 43 abuts against the axle 31 to retract, so that the rotating block 22 can drive the movable part 9 to slide and unlock.
[0043] Compared with the prior art, the lock of this embodiment can be unlocked by password, key and electric drive. In the case of forgetting the password or losing the key, it can be unlocked by electric drive, which solves the problem of inconvenience in previous use. The overall structure is simple and compact, the layout is reasonable, and the lock is controlled by the knob 2, which is more labor-saving and more convenient to unlock than the traditional push button.
[0044] Finally, it should be noted that the combination lock with an electric unlocking function disclosed in the embodiment of the utility model is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
