The double-side locking function of the intelligent padlock is achieved. A mechanical lock body module comprises an elastic lever, a spiral column and a mechanical lock cylinder with a key hole, and the mechanical lock cylinder can drive the spiral column to rotate under the action of an adaptive mechanical key so as to drive a second driving part to drive an elastic locking pin to linearly move under the rotation of the spiral column through transmission of lever movement of the elastic lever. According to the technical scheme, the technical problems that the middle span of a lock hook of an existing intelligent padlock is large and the miniaturization requirement of a bilateral locking padlock cannot be met due to the fact that the unlocking and locking functions of the padlock are achieved in the mode that a locking pin is driven to rotate in the existing intelligent padlock can be solved.

Description

Technical Field

[0001] The present application relates to the technical field of locks, and in particular to a double-sided unlocking lock module. Background Art

[0002] In places such as subways where it is necessary to open and close passage doors or where there are hanging lock holes, most of the locking in these usage scenarios is generally achieved by padlocks. The main padlocks, smart padlocks, etc. on the market have double-sided locking methods and single-sided locking methods. Regardless of whether it is a double-sided locking method or a single-sided locking method, most of the internal unlocking modules still use the method of driving the locking pin to rotate to achieve the unlocking function of the padlock. This method has relatively high requirements for the placement of the lock core position, and often needs to consider that it is in the same symmetrical plane with the lock hook. The resulting spatial distribution makes the middle span of the lock hook large, which has a great impact on the space utilization of the lock. Therefore, it can only meet the miniaturization needs of padlocks with single-sided locking that will not affect the distance between the lock hooks due to the placement of the motor position, but cannot meet the miniaturization needs of padlocks with double-sided locking.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0030] In one embodiment, Figures 1 to 10As shown, an embodiment of the present application provides a bilateral unlocking lock module 400, which may specifically include a motor lock body module and a mechanical lock body module, wherein the motor lock body module is arranged in the internal space of the padlock housing 100, and the motor lock body module includes two elastic locking pins 410, an elastic locking pin 420 and a power mechanism 430, and the two elastic locking pins 410 are movably locked with the two locking grooves 311 in a one-to-one correspondence under the elastic force, and the elastic locking pin 420 has a first position that locks the two elastic locking pins 410 and a second position that unlocks the two elastic locking pins 410, and the elastic locking pin 420 is also respectively provided with a first driving part 4211 and a second driving part 4212, and the first driving part 4211 is drivingly connected to the power mechanism 430, so that under the drive of the power mechanism 430, the first driving part 4211 is driven to drive the elastic locking pin 420 to move linearly, so that the elastic locking pin 420 switches between the first position and the second position. The mechanical lock body module 460 is installed in the internal space of the padlock shell 100. The mechanical lock body module 460 includes an elastic lever 461, a spiral column 462 and a mechanical lock core 463 with a keyhole. The spiral column 462 is driven and connected to the second drive part 4212 through the elastic lever 461. The mechanical lock core 463 can drive the spiral column 462 to rotate under the action of an adapted mechanical key, so that under the rotation of the spiral column 462, the lever movement of the elastic lever 461 is transmitted to drive the second drive part 4212 to drive the elastic locking pin 420 to move linearly, so that the elastic locking pin 420 switches between the first position and the second position.

[0031] It can be understood that the bilateral unlocking module 400 of the embodiment of the present application can be specifically applied to the smart padlock 1 to realize the bilateral unlocking function of the smart padlock 1. The smart padlock 1 generally includes a padlock housing 100, a lock hook 310 and a control component 200. The surface of the padlock housing 100 is provided with two lock hook insertion holes 111 connected to the internal space, and the two ends of the lock hook 310 are respectively recessed with a lock buckle groove 311, and the two ends of the lock hook 310 extend into the internal space through a lock hook insertion hole 111, so as to cooperate with the bilateral unlocking module 400 to realize the bilateral unlocking function of the smart padlock 1. The control component 200 is installed in the internal space of the padlock housing 100 and partially exposed on the front panel of the padlock housing 100, so as to issue a corresponding unlocking instruction after the user performs electronic information identity authentication such as a password or fingerprint, so as to control the power mechanism 430 to perform the corresponding unlocking operation. The first position mentioned above specifically refers to that one end of the elastic locking pin 420 is located between the two elastic upper locking pins 410, so as to prevent each elastic upper locking pin 410 from moving away from the corresponding locking groove 311, thereby locking the two elastic upper locking pins 410. The second position mentioned above specifically refers to that one end of the elastic locking pin 420 is no longer located between the two elastic upper locking pins 410, so that each elastic upper locking pin 410 can move away from the corresponding locking groove 311 under the action of external force, thereby unlocking the two elastic upper locking pins 410.

[0032] In addition, in order to facilitate the quick closing or opening of the installation cavity when the smart padlock 1 is installed or maintained, the padlock housing 100 can be specifically composed of a front shell 110 with a receiving groove and a rear cover 120, so that the opening of the receiving groove is covered by the rear cover 120 to enclose the internal space of the padlock housing 100. The above-mentioned lock hook 310 preferably adopts a U-shaped structure, so that the lock buckle grooves 311 respectively recessed at both ends are arranged oppositely. At this time, the above-mentioned bilateral unlocking lock module 400 can be specifically arranged between the two lock buckle grooves 311. When one end of the elastic locking pin 420 is located between the two elastic upper locking pins 410 to prevent each elastic upper locking pin 410 from moving away from the corresponding lock buckle groove 311, the smart padlock 1 is in a bilateral locking state. When one end of the elastic locking pin 420 is no longer between the two elastic upper locking pins 410, the smart padlock 1 is in a bilateral unlockable state. At this time, the lock hook 310 can be pulled out by external force, so that the two elastic locking pins 420 are squeezed by the external force and move away from the corresponding lock buckle grooves 311, thereby realizing bilateral unlocking of the smart padlock 1. In order to facilitate the two elastic locking pins 420 to be squeezed by the external force to separate from the corresponding lock buckle grooves 311 when the lock hook 310 is pulled out by external force, the lock buckle groove 311 in this embodiment preferably adopts an arc groove structure, and at the same time, the part where the elastic upper locking pin 410 is inserted into the lock buckle groove 311 adopts a spherical structure.

[0033] In this way, the embodiment of the present application is provided with the above-mentioned structure, and its bilateral unlocking and locking module 400 can realize the one-to-one corresponding movable locking connection between the two elastic upper locking pins 410 and the two locking grooves 311 by driving the elastic locking pin 420 to move linearly through the power mechanism 430, that is, realize the bilateral locking function of the smart padlock 1. At the same time, because its elastic locking pin 420 adopts the linear movement method to realize the bilateral locking function of the smart padlock 1, it can avoid the problem of large middle span of the lock hook 310 caused by the rotating structure of the locking pin, so that the space utilization rate of the smart padlock 1 is higher, and then the smart padlock 1 can be miniaturized. In addition, its bilateral unlocking and locking module 400 takes into account the motor lock body module and the mechanical lock body module 460 at the same time, so that the motor unlocking function and the emergency mechanical unlocking function do not affect each other, which not only further improves its space utilization rate, is conducive to its miniaturized design, but also facilitates maintenance and improves the efficiency of derivative design.

[0034] In some examples, such as Figure 2 , Figure 3 and Figure 5 As shown, the bilateral unlocking and locking module 400 also includes a first sealed housing 440, and the first sealed housing 440 has a first cavity and a second cavity connected to each other, and the power mechanism 430 is sealed in the first cavity. The first sealed housing 440 is also provided with two pin holes (not shown in the figure) connected to the second cavity, each pin hole is arranged opposite to a locking groove 311, and an elastic upper locking pin 410 is movably installed in each pin hole, so that each elastic upper locking pin 410 is movably locked with the corresponding locking groove 311 under elastic force, and the elastic locking pin 420 is movably installed in the second cavity, so that under elastic force, one end of the elastic locking pin 420 is located between the two elastic upper locking pins 410 (that is, the elastic locking pin 420 is in the first position), and the other end of the elastic locking pin 420 also extends to the first cavity and is drivingly connected with the power mechanism 430. In this way, the above-mentioned structural arrangement can realize the reasonable layout of the two elastic locking pins 410, the elastic locking pin 420 and the power mechanism 430, while forming better independent sealing and waterproof protection for the power mechanism 430.

[0035] It can be understood that each elastic locking pin 410 can be specifically composed of a locking pin body 411 with a spherical end and a locking pin spring 412, that is, the locking pin body 411 is movably assembled in the corresponding pin hole through the locking pin spring 412, and in order to optimize its structural composition and make the overall structure of the smart padlock 1 more compact, the two elastic locking pins 410 can share a locking pin spring 412, that is, the two locking pin bodies 411 are movably assembled in the corresponding pin holes through the same locking pin spring 412, and at this time, the two ends of the locking pin spring 412 respectively abut against a locking pin body 411.

[0036] In some examples, such as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the elastic locking pin 420 includes a locking pin body 421 and a locking pin spring 422. One end of the locking pin body 421 is placed in the second cavity, and the other end of the locking pin body 421 extends into the first cavity and is elastically mounted on the cavity wall of the first cavity through the locking pin spring 422, so that under the elastic force of the locking pin spring 422, one end of the locking pin body 421 is located between the two elastic upper locking pins 410 (that is, the elastic locking pin 420 is in the first position) to prevent each elastic upper locking pin 410 from moving away from the corresponding locking groove 311. The first driving part 4211 and the second driving part 4212 are respectively arranged at the other end of the locking pin body 421. In this way, the elastic locking pin 420 can be better assembled in the first sealing housing 440 through the above-mentioned structural arrangement. Furthermore, the power mechanism 430 includes a driving wheel 431, a power motor 432 for driving the driving wheel 431 to rotate, a rack 433 and a fixing plate for the rack 433. The fixing plate for the rack 433 is fixed on the cavity wall of the first cavity, and a rack 433 slot extending along the length direction of the locking pin body 421 is provided on the fixing plate for the rack 433. The rack 433 is slidably arranged on the slot of the rack 433 and meshedly connected with the driving wheel 431 so as to drive the rack 433 to move back along the slot of the rack 433 through the driving wheel 431. A power column 4331 is also protruding on the rack 433, and the power column 4331 is abutted and connected with the first driving part 4211 so that when the power column 4331 moves linearly following the rack 433, the first driving part 4211 is pressed to make the other end of the locking pin body 421 move linearly toward the locking pin spring 422. In this way, the above-mentioned structural setting can be used to achieve that the power mechanism 430 can better drive the locking pin body 421 to perform linear motion. At the same time, since the power column 4331 of the power mechanism 430 abuts and squeezes the first driving part 4211 of the locking pin body 421 to make the other end of the locking pin body 421 move linearly toward the locking pin spring 422, that is, there is no fixed connection relationship between the power column 4331 and the first driving part 4211 of the locking pin body 421. Therefore, the other end of the locking pin body 421 can also be moved linearly toward the locking pin spring 422 under the action of other external force mechanisms without causing any influence on the motor movement of the power mechanism 430. This can facilitate the setting of the subsequent mechanical unlocking structure, so that it can well take into account the mechanical unlocking structure and the motor unlocking structure.

[0037] In some examples, such as Figures 4 to 9As shown, the rack 433 is provided with a straight tooth pattern 4332 extending along the length direction of the locking pin body 421, and the first virtual position 4333 and the second virtual position 4334 are respectively provided on both sides of the straight tooth pattern 4332, wherein the first virtual position 4333 corresponds to the idle position of the driving wheel 431 in the locked state, and the second virtual position 4334 corresponds to the idle position of the driving wheel 431 in the unlocked state. Further, the bilateral unlocking module 400 also includes a first magnetic element 451 and a second magnetic element 452, the first magnetic element 451 is installed on the elastic locking pin 420, and the second magnetic element 452 is installed on the power mechanism 430. The smart padlock 1 also includes a control mainboard, which can sense the first magnetic element 451 to feedback the state of the elastic locking pin 420, and can sense the second magnetic element 452 to feedback the state of the power mechanism 430.

[0038] Thus, through the above-mentioned structure setting, when the smart padlock 1 is Figure 5 When it is in the locked state as shown, its power motor 432 can rotate clockwise so that the gear teeth of the driving wheel 431 reach the first virtual position 4333 and then mesh with the straight teeth 4332 of the rack 433, driving the rack 433 to move downward, and the rack 433 then drives the locking pin body 421 to compress the locking pin spring 422 downward and leave the locked position, so that the elastic locking pin 410 can shrink inward, and the driving wheel 431 is disengaged from the straight teeth 4332 of the rack 433 after rotating a certain angle, so that the gear teeth of the driving wheel 431 reach the second virtual position 4334. At this time, the driving wheel 431 can continue to rotate a certain angle (virtual position), and the position feedback information is fed back by detecting the position of the first magnetic element 451 of the locking pin body 421 and the second magnetic element 452 of the power column 4331. After the driving wheel 431 passes the second virtual position 4334, it stops after a delay of 50ms, completing the motor unlocking process. When the smart padlock 1 is as shown in FIG. Figure 6When it is in the unlocked state as shown, its power motor 432 rotates counterclockwise so that the gear teeth of the driving wheel 431 reach the second virtual position 4334 and then mesh with the straight tooth pattern 4332 of the rack 433, driving the rack 433 to move upward. At this time, the locking pin body 421 moves upward under the elastic recovery force of the locking pin spring 422, filling the space between the two elastic locking pins 410, when the driving wheel 431 is disconnected from the straight tooth pattern 4332 of the rack 433, and the gear teeth of the driving wheel 431 reach the first virtual position 4333, at this time, the driving wheel 431 can still continue to rotate a certain angle (virtual position), and the position of the first magnetic element 451 of the locking pin body 421 and the second magnetic element 452 of the power column 4331 are detected to feedback the position information, and the driving wheel 431 stops after a delay of 50ms after passing the first virtual position 4333, completing the motor locking process. It can be seen that through the setting of the above-mentioned virtual position structure (including the first virtual position 4333 and the second virtual position 4334), the driving wheel 431 will not be blocked in either the locked state or the unlocked state (that is, the position where the motor stops has more spare virtual positions after passing the detection position, ensuring that the motor will not be blocked during normal operation). At the same time, the first magnetic element 451 (specifically, it can be a magnet) and the second magnetic element 452 (specifically, it can be a magnet) work together to perform in-place detection, ensuring that the current unlocked state of the smart padlock 1 can be accurately known.

[0039] In some examples, such as Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, the elastic lever 461 may specifically include a lever body 4611 and a lever torsion spring 4612, and the lever body 4611 is elastically assembled in the first sealed housing 440 (specifically, it may be the first cavity) through the lever torsion spring 4612. In this way, the assembly of the elastic lever 461 in the first sealed housing 440 can be better achieved through the above-mentioned structural arrangement. Further, a spherical surface is provided at one end of the lever body 4611, and a spiral rising surface 4621 is provided on the spiral column 462. The spherical surface and the spiral rising surface 4621 are abutted and matched, so that one end of the lever body 4611 is connected to the spiral column 462 in a transmission connection. The other end of the lever body 4611 is abutted and matched with the second driving part 4212, so that the other end of the lever body 4611 is connected to the second driving part 4212 in a transmission connection. In this way, through the above-mentioned structural arrangement, the elastic lever 461 can better perform lever movement under the action of the spiral column 462, and the movement between the spiral column 462 and the elastic lever 461 is smoother.

[0040] In some examples, such as Figure 4As shown, the spiral column 462 is also provided with a limit ear 4622, and the first sealed shell 440 (specifically, it can be the cavity wall of the first cavity) is also provided with a first limit 441 and a second limit 442 for limiting the rotation angle of the spiral column 462. When the limit ear 4622 is located at the first limit 441, the smart padlock 1 is in a locked state, and when the limit ear 4622 is located at the second limit 442, the smart padlock 1 is in an unlocked state. In this way, the above-mentioned structure can be used to ensure that the mechanical lock core 463 can be rotated at a suitable angle to ensure that the unlocking operation is in place. Furthermore, a transmission convex portion (not shown) is provided at one end of the mechanical lock core 463 away from the keyhole (not shown), and a transmission groove 4623 is provided on the spiral column 462. The transmission convex portion and the transmission groove 4623 are plugged and matched, so that the mechanical lock core 463 can drive the spiral column 462 to rotate under the action of an adapted mechanical key.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. 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 embodiments of the present application.
