Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to an intelligent lock. Background Art

[0002] The Chinese utility model patent document with the authorization announcement number CN203603622U discloses an electronic lock, which includes a housing, an electromagnet, a lock tongue, a stop lever, a reset spring, a micro switch, a double torsion spring and a lock hook. The tail end of the stop lever is connected to the electromagnet, the reset spring is installed on the iron core of the electromagnet, and the double torsion spring and the lock tongue are installed on the housing at the same hinge point; when the lock hook is inserted into the lock tongue and pushes the lock tongue to rotate to the locking position, the reset spring deforms and presses against the stop lever through the top of the iron core so that the upper end of the stop lever and the lower end of the lock tongue are engaged to lock, and the top of the lock tongue presses against the micro switch to provide a locking signal; when the electromagnet is energized, the iron core of the electromagnet pulls the stop lever to disengage the stop lever and the lock tongue, and the lock tongue pops out the lock hook through the deformation of the double torsion spring to unlock, and the top of the lock tongue is separated from the micro switch to provide an unlocking signal. The electronic lock improves the safety performance of the electronic lock to a certain extent, especially in terms of anti-riot, anti-pry and anti-vibration.

[0003] However, when this type of electronic lock is used in certain application scenarios, such as in banks or express logistics transport vehicles, the transport vehicles will experience various bumps and vibrations during driving, which may cause the electromagnet inside the electronic lock to shake. Especially in the event of a collision, the excessive impact force will cause the electromagnet to drive the stop lever to rotate significantly. This shaking may cause the stop lever and the lock tongue to accidentally disengage, causing the electronic lock to be opened when it should not be unlocked, greatly reducing its safety.

It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, it is stated that the embodiments described below are only used to explain the utility model and are not used to limit the utility model.

[0031] It should be noted that the terms "install", "set", "connect", "fix" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0032] See also Figures 1 to 4The present embodiment provides a smart lock, including a lock body 1 and a lock tongue 2. The lock body 1 includes a lock shell 101, two lock hooks 102 symmetrically mounted in the lock shell 101, a first reset spring 103 arranged between the lower ends of the two lock hooks 102, two stop hooks 104 symmetrically mounted in the lock shell 101, a second reset spring 105 arranged between the lower ends of the two stop hooks 104, and an unlocking mechanism 106 installed in the shell, and the driving end of the unlocking mechanism 106 is provided with two rotating protrusions 1061.

[0033] When the lock tongue 2 is inserted into the two lock hooks 102 and pushes the two lock hooks 102 to rotate to the locked position, the first return tension spring 103 and the second return tension spring 105 are deformed, and the lower ends of the two lock hooks 102 respectively engage with the upper ends of the two stop hooks 104 to lock. At this time, the lock hooks 102 cannot rotate, thereby locking the lock tongue 2 on the two lock hooks 102; in addition, the driving end of the unlocking mechanism 106 will also drive the two rotating protrusions 1061 to rotate to the outside of the lower ends of the two stop hooks 104 respectively to prevent the lower ends of the two stop hooks 104 from rotating outward, which can effectively prevent the stop hook 104 from rotating significantly due to various external bumps and vibrations, causing the stop hook 104 and the lock hook 102 to accidentally disengage.

[0034] When the unlocking mechanism 106 receives the unlocking signal, the driving end of the unlocking mechanism 106 drives the two rotating protrusions 1061 to rotate to the inner side of the lower ends of the two stop hooks 104 and push the two stop hooks 104 to rotate to the unlocking position, and the lower ends of the two lock hooks 102 are respectively disengaged from the upper ends of the two stop hooks 104, and the two lock hooks 102 eject the lock tongue 2 to unlock through the deformation of the first reset tension spring 103. After the lock tongue 2 is ejected, the driving end of the unlocking mechanism 106 drives the two rotating protrusions 1061 to rotate to the initial position respectively, waiting for the next locking.

[0035] It should be noted that in some special circumstances, if the weight of the lock hook 102 is relatively large, the two lock hooks 102 are unable to pop out the lock tongue 2 through the deformation of the first reset spring 103 when unlocking, and manual assistance is required to remove the lock tongue 2. If the lock tongue 2 is not removed within a preset time, the driving end of the unlocking mechanism 106 will re-drive the two rotating protrusions 1061 to rotate to the outer sides of the lower ends of the two stop hooks 104 respectively, and the upper ends of the two stop hooks 104 will re-engage with the lower ends of the two lock hooks 102 under the deformation action of the second reset spring 105 to lock, thereby ensuring the safety of the lock and the convenience of use.

[0036] The smart lock provided in this embodiment adopts a double locking mechanism, namely, the engagement of the lock hook 102 and the stop hook 104 and the blocking of the stop hook 104 by the rotating protrusion 1061, thereby greatly enhancing the safety performance of the lock. This design can effectively prevent the lock hook 102 and the stop hook 104 from accidentally disengaging due to various external bumps and vibrations, so that the lock tongue 2 is opened without authorization, thereby improving the stability and reliability of the lock, and is suitable for specific application scenarios such as banks or express logistics transportation vehicles; the unlocking mechanism 106 is cleverly designed, and by driving the rotating protrusion 1061 is used to control the stop hook 104, and then control the locking and unlocking of the lock hook 102 and the lock tongue 2. This design not only makes the unlocking process more convenient and quick, but also can effectively prevent the lock from failing due to misoperation or malicious damage. In addition, since the lock body 1 is provided with two lock hooks 102, the two lock hooks 102 act at the same time, which can greatly enhance the locking force of the lock body 1, so that the lock tongue 2 is more firmly locked on the lock body 1. This design can effectively prevent external force from trying to pry open or damage the lock body 1, thereby greatly improving the safety of the lock.

[0037] See also Figures 1 to 3 In one embodiment, the unlocking mechanism 106 includes a motor 1062, a first gear 1063 connected to the output shaft of the motor 1062, a second gear 1064 meshing with the first gear 1063, a third gear 1065 meshing with the second gear 1064, and two rotating protrusions 1061. The motor 1062 is installed in the lock housing 101 through a motor pressure plate 1066, the second gear 1064 and the third gear 1065 are symmetrically arranged below the lower ends of the two stop hooks 104, and the two rotating protrusions 1061 are symmetrically arranged on the upper surfaces of the second gear 1064 and the third gear 1065, respectively. The unlocking mechanism 106 adopts a gear transmission mode, and the first gear 1063, the second gear 1064 and the third gear 1065 are driven to rotate by the motor 1062, and then the two rotating protrusions 1061 are driven to rotate by the second gear 1064 and the third gear 1065, so as to realize accurate control of the two rotating protrusions 1061 to rotate to the outer side of the lower end of the two stop hooks 104, or to rotate to the inner side of the lower end of the two stop hooks 104 and push the two stop hooks 104 to rotate to the unlocking position, or to the initial position, so as to realize the function of locking or unlocking, and the whole unlocking mechanism 106 has a compact structure and occupies a small space, and the gear transmission is efficient, so as to ensure the rapid and accurate unlocking action; by symmetrically arranging the second gear 1064 and the third gear 1065 below the lower end of the two stop hooks 104, and symmetrically arranging the two rotating protrusions 1061 on the upper surface of the gears, this symmetrical design makes the unlocking mechanism 106 more uniform when subjected to force, reduces the wear or failure caused by uneven force, and enhances the stability and durability of the mechanism.

[0038] In some specific embodiments, the motor 1062 is a turbine reduction motor, which can convert high-speed input into low-speed high-torque output through the interaction between the turbine and the worm. This feature enables the motor 1062 to provide smooth and powerful power when driving the unlocking mechanism 106, ensuring that the rotating protrusion 1061 can accurately and reliably rotate to the specified position to achieve the locking or unlocking function. In addition, the turbine reduction motor also has many advantages such as low noise and vibration, strong adaptability and durability, flexible control and easy maintenance.

[0039] See also Figures 1 to 4 In one embodiment, a first micro switch 107 is provided in the lock housing 101 for sensing whether the lock hook 102 has reached the locking position. When the lock tongue 2 is inserted into the two lock hooks 102 and pushes the two lock hooks 102 to rotate to the locking position, the lock hook 102 will resist the first micro switch 107. At this time, the first micro switch 107 senses that the lock hook 102 has reached the locking position, and provides a locking signal to the unlocking mechanism 106, so that the unlocking mechanism 106 drives the two rotating protrusions 1061 to rotate to the outer side of the lower end of the two stop hooks 104 respectively, so as to prevent the lower ends of the two stop hooks 104 from rotating outward. The provision of the first micro switch 107 helps to realize the automatic control of the smart lock. Once the lock hook 102 reaches the locking position and triggers the first micro switch 107, the unlocking mechanism 106 will immediately receive the locking signal and automatically drive the rotating protrusion 1061 to rotate to the outer side of the lower end of the stop hook 104 to complete the locking process.

[0040] See also Figures 1 to 4 In one embodiment, a second micro switch 108 is provided in the lock housing 101 for sensing whether the stop hook 104 has reached the unlocking position. When the lower ends of the two stop hooks 104 rotate to the unlocking position, the stop hooks 104 will abut against the second micro switch 108. At this time, the second micro switch 108 senses that the stop hook 104 has reached the unlocking position and provides an unlocking success signal to the unlocking mechanism 106. The provision of the second micro switch 108 helps to realize the intelligent management of the smart lock. By sensing the state of the stop hook 104 in real time, the second micro switch 108 can provide an unlocking success signal to the unlocking mechanism 106, thereby triggering a subsequent unlocking action or issuing a corresponding prompt message.

[0041] See also Figures 1 to 4In one embodiment, a third micro switch 109 is provided in the lock housing 101 for sensing whether the rotating protrusion 1061 rotates to the outer side of the lower end of the stop hook 104. The provision of the third micro switch 109 ensures that the rotating protrusion 1061 can accurately rotate to the outer side of the lower end of the stop hook 104. When the rotating protrusion 1061 reaches the predetermined position, it triggers the third micro switch 109, thereby providing a feedback signal to the unlocking mechanism 106. This mechanism helps to ensure the correctness and integrity of the locking operation and prevents locking failure caused by the rotating protrusion 1061 not reaching the specified position.

[0042] In one embodiment, a fourth micro switch (not shown in the figure, the same below) is provided in the lock housing 101 for sensing whether the rotating protrusion 1061 rotates to the inner side of the lower ends of the two stop hooks 104 and pushing the two stop hooks 104 to rotate to the unlocking position. The provision of the fourth micro switch ensures the accurate execution of the unlocking operation. When the rotating protrusion 1061 correctly pushes the stop hook 104 to rotate, the fourth micro switch will be triggered, thereby confirming the successful completion of the unlocking operation. This mechanism improves the accuracy and reliability of unlocking, and effectively avoids unlocking failures caused by improper operation or mechanical failures.

[0043] See also Figures 1 to 4 In one embodiment, a fifth micro switch 110 is provided in the lock housing 101 to sense whether the rotating protrusion 1061 rotates to the initial position. The provision of the fifth micro switch 110 ensures that the rotating protrusion 1061 can accurately return to the initial position after completing the locking or unlocking operation. When the rotating protrusion 1061 rotates to the initial position, it triggers the fifth micro switch 110, thereby providing a feedback signal to the unlocking mechanism 106 or the control system. This mechanism helps to ensure the correct reset of the unlocking mechanism 106 and prepare for the next operation.

[0044] In some specific embodiments, the first micro switch 107, the second micro switch 108, the third micro switch 109, the fourth micro switch and the fifth micro switch 110 are all micro switches with handles. The use of micro switches with handles will bring multiple advantages to the smart lock, such as convenient operation, high sensitivity, high reliability, long life, and good waterproof and dustproof performance. These advantages make micro switches with handles an ideal choice in the design of smart locks, providing users with a more convenient, safe and reliable use experience.

[0045] See also Figures 1 to 3In one embodiment, the lower end of the lock hook 102 is provided with a first locking groove 1021, and the upper end of the stop hook 104 is provided with a second locking groove 1041 that matches the first locking groove 1021. When locking, the first locking groove 1021 and the second locking groove 1041 are engaged, and when unlocking, the first locking groove 1021 and the second locking groove 1041 are disengaged. Since the engagement of the first locking groove 1021 and the second locking groove 1041 is achieved through a mechanical structure rather than relying on electronic components or a complex control system, its working stability and life are relatively high. This mechanical locking method is not easily affected by factors such as the environment, temperature or electromagnetic interference, thereby ensuring the long-term stable operation of the smart lock.

[0046] See also Figures 1 to 4 In one embodiment, a U-shaped groove 1022 is provided at the upper end of the lock hook 102, and the lock tongue 2 includes a lock tongue fixing plate 201, two lock tongue side plates 202 respectively arranged at the front and rear sides of the lower end of the fixing plate, and two lock tongue sleeves 203 respectively arranged between the left and right sides of the lower ends of the two lock tongue side plates 202. The setting of the U-shaped groove 1022 enables the lock tongue sleeve 203 to be firmly locked therein, forming a stable and difficult-to-break locking structure. When the two lock tongue sleeves 203 of the lock tongue 2 are respectively locked into the U-shaped grooves 1022 of the two lock hooks 102, they jointly form a strong locking force, effectively preventing illegal intrusion or external force damage.

[0047] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0048] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
