Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, specifically to a smart lock. Background Technology

[0002] A smart lock is a type of lock that differs from traditional mechanical locks in that it is more intelligent in terms of user identification, security, and management. A smart lock is the locking mechanism in an access control system. Electronic locks cannot be called smart locks; the true sign of a smart lock's intelligence is its ability to be remotely controlled via smartphone and integrated with smart home systems.

[0003] Currently, the lock cylinder in most smart locks is designed as a single unit, requiring the lock body to be made into parts or installed through side openings. This significantly increases the risk of water ingress, leading to damage to the smart lock. Furthermore, existing smart locks suffer from the following problems:

[0004] Increased complexity: Setting up and managing smart locks is generally more complex than traditional locks, which can be challenging for users who are not very familiar with technology. Furthermore, troubleshooting and maintenance also require more expertise.

[0005] Higher cost: High-quality smart locks are usually more expensive than traditional locks, and due to the need for complex structures or multiple complex processing techniques to ensure waterproofing and other aspects, the cost is increased.

[0006] Insufficient flexibility: Most smart locks on the market are not easy to change once installed, and are limited to the installation location. Or, movable smart locks cannot be fixed in place. When moving items such as safes, they may shake during the transportation process, which may cause them to bump into people.

[0007] Environmental factors: Extreme weather conditions may affect the function of some smart locks. For example, low temperatures may cause electronic components to work unstably, or high humidity may corrode electronic contacts.

[0008] It may cause some burden to the user; shaking may occur when moving objects locked by the smart lock.

[0009] It also affects the placement of the smart lock; if the environment where the smart lock is installed is humid or near a water source, it may cause corrosion of the internal metal parts or waterproof defects. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0031] The structure of the smart lock provided by this utility model is as follows: Figure 1 , Figure 3 as well as Figure 4 As shown, the lock body 1 includes a lock body 1 with a keyhole on one side. Inside the lock body 1, a circuit board 10 with an alarm module button is installed. The top of the lock body 1 is connected to a lock rod 3 that can move up and down and has a lock groove. One end of the lock rod 3 is fitted with a limiting cylinder 31, and two sealing rings 32 are installed between the limiting cylinder 31 and the lock rod 3. The sealing rings 32 are used for sealing the lock rod 3. A battery 4 is fixed at the bottom inside the lock body 1. The lock body 1 also has a lower micro switch 6 and a side micro switch 7 installed inside. The surface of the lock body 1 is bolted to a top cover 2. A sealing gasket 11 is installed between the lock body 1 and the top cover 2. The sealing gasket 11 is used to block the splashing and water spraying function of the front water source. The surface of the top cover 2 is fitted with a glass 21 and a nameplate 22 from bottom to top.

[0032] The lock cylinder in common smart locks is usually designed as a single unit, requiring the main body to be made into parts or holes to be drilled on the side for installation. This greatly increases the risk of water ingress and damage to the smart lock. This utility model makes the lock cylinder module 53 into a single module, which is then installed into the space reserved in the inner cavity of the smart lock and fixed in place with screws. This greatly improves installation efficiency, reduces labor costs, and eliminates the need to make the outer shell of the smart lock into parts or drill separate holes, thus greatly improving the waterproof performance of this smart lock.

[0033] Adding a sealing ring 32 at the locking rod 3 can prevent splashing and water from getting in, effectively protecting the internal circuitry and internal structure in a dry environment.

[0034] Adding a sealing gasket 11 between the lock body 1 and the top cover 2 can effectively prevent water from splashing or dripping from the front, thus protecting the circuit board 10 and improving the stability of the smart lock.

[0035] An alarm module button is provided on the circuit board 10. The signal of the circuit board 10 can be connected to the server. After the top cover 2 is installed, the alarm module button will be pressed down due to the pressure to achieve the use mode. If the parts are disassembled without the permission of the internal personnel, the alarm module button will automatically rebound after the top cover 2 is released, and an alarm will be sounded. At the same time, feedback will be sent back to the server.

[0036] Furthermore, such as Figure 2 , Figure 5 as well as Figure 6 As shown, a lock-on / lock-off mechanism 5 is provided inside the lock body 1 and on one side of the battery 4. The lock-on / lock-off mechanism 5 is used for the opening and closing of the smart lock. The lock-on / lock-off mechanism 5 includes a motor 51, a transmission module 52, and a lock cylinder module 53. The motor 51 is installed inside the lock body 1. The lock cylinder module 53 is installed inside the lock body 1 and is transmitted to the motor 51 through the transmission module 52. The transmission module 52 consists of a gear set 521, a worm gear 522, and a stepping laser reader 523. The output end of the motor 51 is equipped with the gear set 521, and the output end of the gear set 521 is equipped with the worm gear 522. The worm gear 522 and the worm 532 cooperate to transmit the transmission. The stepping laser reader 523 is installed on the housing of the motor 51. The stepping laser reader 523 is used to transmit the number of rotations and status of the worm gear 522 to the circuit board 10.

[0037] During implementation, the locking rod 3 is aligned with the lock hole of the lock body 1 and pressed to the bottom, so that it presses down the lower micro switch 6. Then, the motor 51 generates force to drive the worm gear 522 to rotate to the left under the action of the gear set 521. When the gear set 521 rotates, it transmits the number of rotations back to the circuit board 10 through the step laser recognition device 523. At the same time, the rotation of the worm gear 522 causes the worm 532 to move horizontally to the right along the lock cylinder seat 531 under the limit of the limit rod 533 until it is locked in the lock groove of the locking rod 3. Since the movement of the worm gear 532 will drive the limit rod 533 to move, the limit rod 533 will contact the side micro switch 7 to complete the locking process.

[0038] Furthermore, such as Figure 3 , Figure 5 as well as Figure 6 As shown, the lock cylinder module 53 consists of a lock cylinder seat 531, a worm gear 532, and a limiting rod 533. The lock cylinder seat 531 with a limiting groove is installed inside the lock body 1 by bolts. The worm gear 532 is slidably connected inside the lock cylinder seat 531. The limiting rod 533 is fixed on the surface of the worm gear 532, and one end of the limiting rod 533 passes through the limiting groove of the lock cylinder seat 531. In the locked state, the bottom end of the limiting rod 533 contacts the side micro switch 7.

[0039] The main body and internal structure of the smart lock in this invention are not limited to one material and can be replaced with other highly reliable materials.

[0040] The smart lock of this invention is quite practical: compared with existing smart locks, this patent is more flexible and easier to use.

[0041] The smart lock of this invention is more reliable: its components have sufficient strength to withstand minor external impacts such as impacts, drops, squeezing, and rain; internal structural parts are self-lubricating and wear-resistant, greatly improving its service life. Furthermore, the terminal receives a signal when someone forcibly removes the smart lock.

[0042] The smart lock of this invention is more environmentally friendly: the materials and processing of the smart lock do not produce harmful gases or substances, and all components can be recycled after use.

[0043] During implementation, the motor 51 generates force, which drives the turbine 522 to rotate to the right under the action of the gear set 521. The stepping laser recognition device 523 transmits the number of rotations and status to the circuit board 10. At the same time, the rotation of the turbine 522 causes the worm gear 532 to move to the left along the lock cylinder seat 531 under the limit of the limit rod 533, and is pulled out from the lock groove of the lock rod 3. Then the lock rod 3 is pulled up to complete the unlocking process.

[0044] Working principle: When in use, align the locking rod 3 with the lock hole of the lock body 1 and press it to the bottom, so that it presses down the lower micro switch 6. Then, the motor 51 generates force to drive the worm gear 522 to rotate to the left under the action of the gear set 521. When the gear set 521 rotates, it will transmit the number of rotations back to the circuit board 10 through the step laser recognition 523. At the same time, the rotation of the worm gear 522 will cause the worm 532 to move horizontally to the right along the lock cylinder seat 531 under the limit of the limit rod 533 until it is locked in the lock groove of the locking rod 3. Since the movement of the worm gear 532 will drive the limit rod 533 to move, the limit rod 533 will contact the side micro switch 7 to complete the locking process.

[0045] During unlocking, the motor 51 generates force, which drives the turbine 522 to rotate to the right under the action of the gear set 521. The stepping laser recognizer 523 transmits the number of rotations and status to the circuit board 10. At the same time, the rotation of the turbine 522 causes the worm gear 532 to move to the left along the lock cylinder seat 531 under the limit of the limit rod 533, and is pulled out from the lock groove of the lock rod 3. Then the lock rod 3 is pulled up to complete the unlocking process.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
