Description

Technical Field

[0001] This invention relates to the field of electronic lock technology, and more specifically, to an electronic lock device. Background Technology

[0002] Currently, most locks used in lockers, storage lockers, and mail lockers (boxes) rely on electromagnets to generate unlocking force, which is then transmitted through a simple mechanical lever to open the lock and thus the lock door.

[0003] The components of a cabinet door unlocking system generally include a shell, cover, electromagnet, return spring, emergency pull rod, stop pawl, locking plate, torsion spring, pivot, and screws. These electronic locks (electromagnetic locks) have simple linkage structures, resulting in poor security. The main technical defects are as follows: the electromagnet's attraction force is insufficient, leading to weak unlocking force at the stop pawl, causing frequent lock failures and cabinet doors remaining locked; the stop pawl's engagement with the locking plate is minimal, making automatic unlocking easy and resulting in the loss of items.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0038] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0039] like Figures 1-5As shown, the present invention provides an electronic lock device, including: a device body 100, which includes a lock housing 1, a latch 2, an inner drive 3, and a motor body 4. The latch 2, the inner drive 3, and the motor body 4 are all installed inside the lock housing 1. When the motor body 4 is started, it can drive the inner drive 3 to move. Since the latch 2 and the inner drive 3 are movably connected, the inner drive 3 can drive the latch 2 to extend and retract within the lock housing 1. One end of the lock housing 1 has a locking hole 10. So when the device body 100 is installed in place, the motor body 4 drives the inner drive 3 to push the latch 2 out of the lock housing 1 through the locking hole 10, thereby realizing the locking function. This avoids the problem in the prior art where the locking pawl and the locking plate have insufficient engagement, making it easy to automatically unlock and causing the loss of items.

[0040] Exemplary locking tongue

[0041] Furthermore, some embodiments of the present invention provide a specific structure for the above-mentioned latch 2. The latch 2 of this structure includes a tongue plate 21 and a tongue rod 22. The tongue plate 21 is installed inside the lock housing 1. The tongue plate 21 is movably connected to the inner drive member 3 and the lock housing 1. A drive groove 211 is provided on the tongue plate 21. There are multiple protruding teeth 212 on one side of the inner wall of the drive groove 211. The protruding teeth 212 are engaged with the drive output teeth 371 of the inner drive member 3. Therefore, when the inner drive member 3 is started, it finally rotates through the drive output teeth 371, thereby driving the output teeth 371 to move the protruding teeth 212 and the tongue plate 21 in an engaging manner. In this way, the tongue rod 22 at one end of the tongue plate 21 can extend and retract inside the lock housing 1. Moreover, the latch 2 of this structure can move smoothly inside the lock housing 1 with high precision.

[0042] Furthermore, the tongue plate 21 has guide bars 213 on both sides, and guide holes 214 are provided in the guide bars 213. A guide rail shaft 215 is installed in the guide holes 214, and the two ends of the guide rail shaft 215 are connected to the inner wall of the lock housing 1. Therefore, when the inner drive member 3 drives the tongue plate 21 to move, the tongue plate 21 moves along the guide rail shaft 215 through the guide holes 214, realizing the above-mentioned smooth movement process.

[0043] Exemplary internal drive

[0044] Furthermore, some embodiments of the present invention provide a specific structure of the aforementioned internal drive component 3. The internal drive component 3 includes a fixed frame 32 and a reduction assembly 33. The motor body 4, the fixed frame 32, and the reduction assembly 33 are all installed inside the lock housing 1. The motor body 4 is installed at one end of the fixed frame 32 and away from the locking hole 10. The reduction assembly 33 is installed on one side of the fixed frame 32, while the latch 2 is installed on the other side of the fixed frame 32. The lock housing 1 has a position detection plate 31, which is a Hall plate with a sensing magnet 311. Therefore, after the motor body 4 is started, it can be driven to extend and retract within the lock housing 1 by the reduction of the reduction assembly 33. The extension and retraction of the latch 2 can be precisely controlled by the sensing magnet 311 and the position detection plate 31.

[0045] Furthermore, the aforementioned reduction assembly 33 includes multiple reduction gears, specifically, it may include a first gear 34, a second gear 35, a third gear 36, and a fourth gear 37. The first gear 34, second gear 35, third gear 36, and fourth gear 37 are rotatably mounted on the fixed frame 32 via corresponding shafts. The first gear 34, serving as the initial input gear, is movably connected to the motor body 4. Here, a worm gear 40 is mounted on the output shaft of the motor body 4, so the first gear 34 acts as a worm, driving the motor body 4 when it starts. The worm gear 40 rotates, which in turn drives the first gear 34 to rotate, which in turn drives the second gear 35 to rotate, the second gear 35 drives the third gear 36 to rotate, and finally the fourth gear 37 to rotate, thus realizing the speed reduction function of the reduction assembly 33 on the motor body 4. The drive output tooth 371 of the fourth gear 37 drives the convex tooth 212 on the tongue plate 21 to move, and the tongue plate 21 extends and retracts within the lock housing 1, thereby completing the process of the inner drive member 3 driving the lock tongue member 2 to extend and retract within the lock housing 1.

[0046] Exemplary motor mounting assembly

[0047] like Figures 6-17 As shown, further, some embodiments of the present invention provide a specific structure of the internal motor assembly 2, which includes a motor body 4 and a motor fixing assembly 5. The motor body 4 is installed in the motor fixing assembly 5, and the motor fixing assembly 5 can fix the motor body 4 so that the motor body 4 can work smoothly.

[0048] Specifically, the motor fixing assembly 5 includes an outer motor cylinder 51, an inner motor cylinder 52, multiple inner connecting fasteners 53, and multiple outer connecting fasteners 54. The outer motor cylinder 51 is disposed in the lock housing 1, the inner motor cylinder 52 is installed in the outer motor cylinder 51, the multiple inner connecting fasteners 53 are evenly distributed in the inner motor cylinder 52, and the multiple outer connecting fasteners 54 are evenly distributed on the outer wall of the inner motor cylinder 52. The inner connecting fasteners 53 and the outer connecting fasteners 54 correspond one-to-one. When in use, the motor body 4 is placed in the inner motor cylinder 52, and the multiple inner connecting fasteners 53 and the multiple outer connecting fasteners 54 can fix the motor body 4. Furthermore, the aforementioned multiple inner connecting fasteners 53 and the multiple outer connecting fasteners 54 facilitate subsequent disassembly and maintenance, and the disassembly process is relatively convenient, simple, and efficient.

[0049] Exemplary Inline Firmware

[0050] Furthermore, some embodiments of the present invention provide a specific structure of the aforementioned inline fastener 53. The inline fastener 53 includes an arc-shaped inner moving plate 531, a first spring body 532, a spring seat 533, an inverted L-shaped guide plate 534, and an inner brake 535. The arc-shaped inner moving plate 531 is installed in the inner motor cylinder 52. The inner side of the spring seat 533 is connected to the support plate 5311 at the bottom of the arc-shaped inner moving plate 531. The inverted L-shaped guide plate 534 is installed on the outer side of the spring seat 533 and is movably connected to the inner brake 535 in the inner motor cylinder 52. Two first spring bodies 532 are installed in the spring seat 533. One end of the first spring body 532 is connected to the bottom of the inner motor cylinder 52, and the other end is connected to the spring seat 533. The rear end of the aforementioned inner motor cylinder 52 has a rear retaining ring 521. The rear retaining ring 521 has multiple arc-shaped slots (not shown), and the aforementioned support plate 5311 passes through the arc-shaped slots.

[0051] Therefore, during use, the motor body 4 can be placed inside the inner motor cylinder 52. The outer convex ring 41 on the motor body 4 then abuts against multiple arc-shaped inner moving plates 531, causing the multiple arc-shaped inner moving plates 531 to move along the length of the motor body 4. In turn, the arc-shaped inner moving plates 531 drive the spring seat 533 to move to the rear side of the inner motor cylinder 52, and the inverted L-shaped guide plate 534 also moves to the rear side, thereby driving the inner brake 535 to enter the inner blind hole 411 of the outer convex ring 41, thus fixing the motor body 4. At the same time, the aforementioned inverted L-shaped guide plate 534 is movably connected to the external fastener 54. The inverted L-shaped support plate 5341 on one side of the inverted L-shaped guide plate 534 drives the aforementioned external fastener 54 to also fix the motor body 4, thereby achieving a double fixing effect, avoiding shaking, and greatly increasing the stable working effect of the motor body 4. The motor body 4 can output a stable and consistent torque.

[0052] Furthermore, an internal anti-slip member 58 is provided between the two adjacent internal fasteners 53. The internal anti-slip member 58 includes a first anti-arc plate 581, multiple internal support springs 582, and a second anti-arc plate 583. The first anti-arc plate 581 and the second anti-arc plate 583 are installed in the inner motor cylinder 52 and located between the two internal fasteners 53. The multiple internal support springs 582 are evenly distributed between the first anti-arc plate 581 and the second anti-arc plate 583. Therefore, after the motor body 4 is placed in the inner motor cylinder 52, on the one hand, the internal fasteners 53 fix the motor body 4, and on the other hand, the multiple internal anti-slip members 58 also fix the motor body 4. That is, the multiple first anti-arc plates 581 are spaced around the outer wall of the motor body 4 to prevent the motor body 4 from moving circumferentially, which helps the internal fasteners 53 to fix the motor body 4.

[0053] Exemplary external firmware

[0054] Furthermore, some embodiments of the present invention provide a specific structure for the external fastener 54 described above. The external fastener 54 includes a first inclined rod 541 and a second inclined rod 542. Here, the first inclined rod 541 is rotatably mounted on the front end of the inner motor cylinder 52 via a torsion spring shaft 543, while the second inclined rod 542 is mounted on the outside of the inner motor cylinder 52. The front end of the second inclined rod 542 is connected to the outer end of the first inclined rod 541, and the lower end is movably connected to the internal fastener 53. Therefore, when the inverted L-shaped support plate 5341 moves to the rear, it drives the second inclined rod 542 to twist. Consequently, the second inclined rod 542 drives the first inclined rod 541 to move the motor body 4. That is, the inner end of the first inclined rod 541 approaches the motor body 4, so that the wear-resistant part 544 mounted on the inner end of the first inclined rod 541 abuts against the outer wall of the motor body 4 to fix the motor body 4.

[0055] Furthermore, the wear-resistant component 544 mentioned above includes two wear-resistant plates 545 and multiple inner spring bodies 546. The two wear-resistant plates 545 are installed at the inner end of the first inclined rod 541, while the multiple inner spring bodies 546 are installed between the two wear-resistant plates 545. In this way, the wear-resistant component 544 can flexibly contact the motor body 4, and while fixing the motor body 4, it will not cause wear to the outer wall of the motor body 4.

[0056] Exemplary internal brake

[0057] Furthermore, some embodiments of the present invention provide a specific structure for the aforementioned inner brake member 535. This inner brake member 535 includes two guide plates 536, a brake cap 537, and a convex brake body 538. The two guide plates 536 are installed in the inner motor cylinder 52, and the brake cap 537 is installed between the two guide plates 536. A side guide groove 5361 is provided on the guide plate 536, and a guide protrusion 5371 is correspondingly installed on the outer wall of the brake cap 537, allowing the guide protrusion 5371 to enter the side guide groove 5361. Further, in the braking... The moving cap 537 is also equipped with a convex brake body 538 and a second spring body 539. The second spring body 539 abuts against the convex brake body 538. So when the outer convex ring 41 abuts against the arc-shaped inner moving plate 531 and moves to the rear, the inner blind hole 411 on the outer convex ring 41 corresponds to the convex brake body 538. Under the action of the second spring body 539, the convex brake body 538 is pushed outward into the inner blind hole 411. The guide convex body 5371 moves along the side guide groove 5361 to prevent the convex brake body 538 from tilting, thereby realizing the fixing of the motor body 4 by the convex brake body 538.

[0058] Furthermore, to make the convex brake body 538 more securely fixed to the motor body 4, a side inner hole 5372 is provided on the inner wall of the brake cap 537. A spring telescopic member 54 is installed in the side wall of the convex brake body 538. So when the convex brake body 538 moves inside the brake cap 537, the spring telescopic member 54 can correspondingly enter into the side inner hole 5372, thus the convex brake body 538 is firmly inside the brake cap 537. Furthermore, a third spring body 5373 is installed at the rear end of the brake cap 537, and the third spring body 5373 is connected to the inner wall of the inner motor cylinder 52. A side conductor 522 is installed at the lower end of the barrel 52. The side conductor 522 has a notched guide wall 523, so the front end of the inverted L-shaped guide plate 534 can enter the notched guide wall 523. So when the inverted L-shaped guide plate 534 moves backward, it pushes against the side conductor 522, causing the side conductor 522 to drive the brake cap 537 to move inward to near the outer convex ring 41. The aforementioned third spring body 5373 helps to pull the brake cap 537 outward when disassembling the motor body 4, releasing the convex brake body 538 from fixing the outer convex ring 41, thereby allowing the motor body 4 to be removed from the inner motor barrel 52.

[0059] Exemplary quick-release component

[0060] Furthermore, in some embodiments of the present invention, a quick-release assembly 55 is also installed at the front end of the inner motor cylinder 52. Specifically, the quick-release assembly 55 of this structure includes an outer turntable 551 and a plurality of inner release seats 552. Here, the outer turntable 551 is installed at the front end of the inner motor cylinder 52, and the plurality of inner release seats 552 are evenly distributed in the inner motor cylinder 52 and located above the inner brake member 535. A Y-shaped movable member 56 and two inner pull blocks 57 are movably installed on the inner release seat 552. Here, an L-shaped quick-release rod 573 is installed at the bottom of the two inner pull blocks 57, and the lower end of the L-shaped quick-release rod 573 corresponds to the spring telescopic member 54 in the side inner hole 5372. The movable plate 561 of the Y-shaped movable member 56 is connected to the bottom of the outer turntable 551.

[0061] Therefore, when the operator disassembles the motor body 4, the outer turntable 551 is moved to one side. The outer turntable 551 then drives the multiple inner disassembly seats 552 on the rear side to move. The movable plate 561 then drives the Y-shaped movable part 56 to move the two inner pull blocks 57. The two inner pull blocks 57 then move inward. The L-shaped quick release rod 573 at the bottom of the inner pull block 57 then moves the spring telescopic part 54. The spring telescopic part 54 then comes out from the side inner hole 5372, and at the same time moves the motor body 4 outward. The outer convex ring 41 leaves the arc-shaped inner moving plate 531. Under the action of the two first spring bodies 532, the inverted L-shaped guide plate 534 moves inward. Then the aforementioned third spring body 5373 pulls the brake cap 537, which drives the convex brake body 538 to move, releasing the convex brake body 538 from fixing the outer convex ring 41. Thus, the motor body 4 can be taken out from the inner motor cylinder 52.

[0062] Furthermore, the aforementioned inner pull block 57 is movably mounted on the inner disassembly seat 552 via the fourth spring body 571 and the pull block seat 572. The inner disassembly seat 552 has a first inner slot, and the bottom of the inner pull block 57 has the aforementioned L-shaped quick-release rod 573, which passes through the first inner slot. The lower end of the L-shaped quick-release rod 573 corresponds to the spring telescopic member 54 in the side inner hole 5372. The Y-shaped movable member 56 is slidably connected to the inner pull block 57, and the inner disassembly seat 552 has a second inner slot corresponding to the Y-shaped movable member 56. With the above structure, after the motor body 4 is removed, the fourth spring body 571 can pull the inner pull block 57 back to its original position, facilitating subsequent continued use.

[0063] Furthermore, an outer lever 553 is installed on the outer turntable 551, and an outer retaining rod 524 corresponding to the outer lever 553 is installed at the front end of the inner motor cylinder 52. A retaining sleeve 554 is installed between the outer lever 553 and the outer retaining rod 524. The retaining sleeve 554 has a certain degree of elasticity, so by forcefully turning the outer lever 553, the outer turntable 551 can be moved to one side. After releasing the outer lever 553, the outer lever 553 can also move back to its original position under the action of the retaining sleeve 554, which is convenient for subsequent use.
