Description

Technical Field

[0001] This utility model belongs to the field of smart lock technology, and in particular relates to a fully sealed smart electronic lock. Background Technology

[0002] In current smart electronic lock structures, the motor, circuit board, and latch assembly are mostly installed in the same cavity as the lock housing. Because the latch is exposed and has its own telescopic movement characteristics, the electronic lock has poor waterproofing, affecting its outdoor application. For example, helmets on shared electric bikes use electronic locks to prevent helmet loss. Users scan a code to unlock the helmet's electronic lock and ride; when returning the bike, the helmet is also returned, and the electronic lock locks it again. Currently, the electronic locks used in helmets on the market have poor waterproofing, which can damage the motor and circuit board inside the lock, affecting its normal operation and sometimes even causing the lock to malfunction, thus hindering normal bike return.

[0003] To improve the waterproof performance of smart electronic locks and enable them to be used normally in outdoor environments, some electronic lock structures have been improved. For example, a sealing structure has been set between the lock tongue and the lock tongue hole, or the motor and circuit board inside the electronic lock have been sealed with sealant, or waterproof components such as waterproof motors and waterproof circuit boards have been directly selected. These improvements have led to a more complex overall lock structure, a more complex manufacturing process, and higher production costs, making lock production more difficult. Utility Model Content

[0004] In view of this, the present invention aims to propose a fully sealed intelligent electronic lock with a simple structure and easy manufacturing, which improves the waterproof performance of the lock and is suitable for outdoor applications.

Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 , Figure 2 and Figure 7 As shown, the fully sealed intelligent electronic lock includes a lock housing 1 with a bolt hole 105. A front port is provided on the front of the lock housing 1, which is matched with a front cover 9 and sealed by the front cover 9. A rear port is provided on the back of the lock housing 1, which is matched with a rear cover 8 and sealed by the rear cover 8. A bolt assembly, circuit board, motor, and transmission mechanism are provided inside the lock housing 1.

[0033] Lock case 1 structure as follows Figure 3 , Figure 4As shown, the lock housing 1 has a front cavity 102 facing forward and a rear cavity 101 facing backward. The rear cavity 101 and the front cavity 102 are not connected. The front cavity 102 is used to house the bolt assembly, and the rear cavity 101 is used to house the circuit board, motor, and transmission mechanism. The bolt hole 105 is provided corresponding to the front cavity 102, and the front port of the lock housing 1 is provided corresponding to the front cavity 102, which is sealed by the front cover 9. The rear port of the lock housing 1 is provided corresponding to the rear cavity 101, which is sealed by the rear cover 8.

[0034] In this utility model, the front cover 9 and the rear cover 8 are both connected and fixed by screws and the lock shell 1. The fit gap between the edge of the rear cover 8 and the shell 1, as well as the gap of the screw holes for fixing, are sealed with sealant to ensure the sealing effect of the rear cavity 101.

[0035] like Figure 5 As shown, the latch assembly 7 is installed in the front cavity 102. The latch assembly 7 includes a latch 71, a locking rod 72, a drive gear 77, and a lever 74. The drive gear 77 is installed at the bottom of the front cavity 102 via a rotating shaft 6. The rotating shaft 6 extends through the bottom of the front cavity 102 into the rear cavity 101. A sealing structure is provided between the rotating shaft 6 and the bottom of the front cavity 102, such as using an oil seal 2 to seal the rotating shaft 6 and the bottom of the front cavity 102. Figure 7 As shown, this is to ensure the isolation effect between the rear cavity 101 and the front cavity 102, to ensure the sealing of the rear cavity 101, and to improve the waterproof effect of the rear cavity 101.

[0036] The latch 71 and the latch hole 105 are slidably connected. One end of the locking rod 72 is fixedly connected to the latch 71, and the other end of the locking rod 72 is provided with a limiting part 76. The lever 74 is slidably fitted on the locking rod 72. A first spring 73 is fitted on the part of the locking rod 72 between the lever 74 and the latch 71, and the first spring 73 abuts against the latch 71 and the lever 74. A second spring 75 is fitted on the part of the locking rod 72 between the lever 74 and the limiting part 76, and the second spring 75 abuts against the limiting part 76 and the lever 74. The corresponding drive gear 77 of the lever 74 is provided with a rack part 741. The rack part 741 meshes with the drive gear 77. When the drive gear 77 rotates, it drives the lever 74 to move.

[0037] Figure 5 The diagram shows the position of the latch 71 when unlocking. At this time, the latch 71 retracts into the latch hole 105, which is the position of the latch when unlocking. When the rack part 741 and the drive gear 77 are engaged to ensure that the latch 71 extends out of the latch hole 105, this is the position of the latch when locking.

[0038] like Figure 6As shown, the circuit board, motor 3, and transmission mechanism are housed within the rear cavity 101. The circuit board is equipped with a sensing and identification device, which includes an identification module and a control module. The identification module is signal-connected to the control module and can identify mobile phone Bluetooth devices or access cards. This technology is well-known to those skilled in the art and will not be described in detail here. The motor 3 is connected to the control module via the circuit board and receives command information from the control module. The transmission mechanism is used to drive the rotating shaft 6 and the motor 3, thereby driving the drive gear 77 to rotate, and subsequently driving the latch assembly 7 to perform corresponding actions.

[0039] The transmission mechanism includes a worm gear 4 and a gear assembly 5. The worm gear 4 is mounted on the motor 3, and the rotating shaft 6 and the worm gear 4 are connected by the gear assembly 5. The structure and principle of this transmission mechanism are well known to those skilled in the art and will not be described in detail here.

[0040] The sensing and identification device senses and identifies external unlocking command information, and then controls the motor 3 to operate, driving the bolt to retract and switch from the locked state to the unlocked state.

[0041] Specifically, when locking, the bolt 71 must first retract into the bolt hole 105 to avoid the edge of the latch. Then, once the bolt 71 and the latch are aligned, the bolt 71 extends and inserts into the latch to lock. This action can be driven by the motor 3. When the motor 3 starts, it drives the lever 74 to move backward (away from the bolt hole). The lever 74 moves and compresses the second spring 75. The elastic force of the second spring 75 drives the locking rod 72 to move backward, causing the bolt 71 to retract into the bolt hole. Once the bolt 71 of the electronic lock is aligned with the latch, the motor 3 reverses its rotation, and the lever 74 moves forward, causing the bolt 71 to move forward and insert into the latch to lock. This action can also be performed without starting motor 3, that is, the toggle block 74 does not need to be activated. Since a first spring 73 is provided between the latch 71 and the toggle block 74, when the latch 71 contacts the edge of the latch, the latch 71 will compress the first spring 73. When the latch 71 passes the edge of the latch as a whole, under the elastic action of the first spring 73, the latch 71 is driven to extend out of the latch hole 105 and enter the latch, thus completing the locking.

[0042] When unlocking, the user brings the door card or a mobile phone with Bluetooth enabled close to the sensing and recognition device. After the sensing and recognition device recognizes the unlocking signal, it controls the motor 3 to turn on, driving the toggle block 74 to move backward, that is, to move away from the bolt hole 105. As the toggle block 74 moves backward, it compresses the second spring 75, causing the lock rod 72 to move backward, and the bolt 71 to retract into the bolt hole 105. At this time, the bolt 71 disengages from the latch, and the unlocking is completed.

[0043] In this utility model, the structure of the lever 74 is as follows: Figure 8As shown, the toggle block 74 is provided with a sliding hole 742 corresponding to the locking rod 72. The toggle block 74 has a first sliding groove 744 on both sides of the sliding hole 742, and a second sliding groove 743 on the end face of the toggle block 74 facing the front cover 9. The first sliding groove 744 and the second sliding groove 743 are both arranged parallel to the sliding hole.

[0044] Front cover 9 structure as Figure 9 As shown, a second slide rail 91 is provided on the inner side of the front cover 9, i.e., the side facing the front cavity 102, corresponding to the second slide groove 743. Two first slide rails 103 are provided on the bottom of the front cavity 102 corresponding to the second slide groove 744, as shown... Figure 4 As shown.

[0045] During assembly, the locking rod 72 passes through the sliding hole 742, and the lever 74 is then slidably fitted onto the locking rod 72. The first sliding groove 744 and the first sliding rail 103 are slidably connected, and the second sliding groove 743 and the second sliding rail 91 are slidably connected, improving the stability of the lever 74 slidingly installed in the front cavity 102.

[0046] This utility model has a simple and compact structure. It separates and seals the circuit board, motor and locking tongue assembly, which improves the waterproof performance of the circuit board and motor. It eliminates the need for a special waterproof motor and circuit board, reduces costs, and is suitable for outdoor use, such as in shared bicycles and shared electric vehicles.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
