Description
Technical Field
[0001] This utility model relates to the field of smart lock technology, and in particular to a lever-handle smart lock. Background Technology
[0002] With the continuous advancement of technology and the improvement of people's living standards, smart locks, as a new type of door lock product, have gradually gained widespread popularity due to their superior security and convenience. Traditional mechanical locks, due to their poor security performance, are gradually failing to meet the security needs of modern society. Therefore, the emergence of smart locks has greatly improved the security performance of door locks and significantly enhanced user convenience by enabling unlocking through multiple methods such as fingerprint recognition, password input, and card swiping.
[0003] However, most existing smart locks use a single electric control method. While this method improves the security of the lock, it also has certain limitations. For example, when the battery runs out or electronic components malfunction, the user may not be able to unlock the lock in time, which undoubtedly causes great inconvenience to the user's life. Especially in emergency situations, this limitation may pose serious security risks.
[0004] Secondly, the existing smart locks have complex structural designs, which not only increase manufacturing costs but also make maintenance difficult. Therefore, in order to improve the applicability of existing smart locks, we propose a lever-handle smart lock. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing smart locks, such as complex structural designs that increase manufacturing costs, and to propose a lever-handle smart lock.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a smart lock with a lever handle, including:
[0008] A first panel with a first handle and a second panel with a second handle;
[0009] A locking rod assembly is provided between the first handle and the second handle. A main circuit board with a fingerprint module and a control component for locking the locking rod assembly are installed inside the first handle. A lock cylinder assembly is also provided on the inner side of the first handle, and the lock cylinder assembly is connected to the control component.
[0010] Furthermore, a secondary circuit board and a battery are fixedly installed inside the second handle. The secondary circuit board is electrically connected to the main circuit board, and an unlocking button exposed on the outside of the second handle is also provided on the secondary circuit board.
[0011] Furthermore, the locking rod assembly includes a square tube passing through the first handle and the second handle, a connecting piece fixedly installed on the outer side of the square tube, and a torsion spring fixedly connected to the connecting piece and the inner side of the first handle.
[0012] A connector through which a door panel passes is connected between the first panel and the second panel.
[0013] Furthermore, the control component includes a fixed plate mounted in the first handle;
[0014] An electric actuator is fixedly installed on the end face of the fixed plate. The shaft end of the electric actuator is connected to a floating seat. A limit rod is fixedly connected to the top of the floating seat. A locking sleeve is fixedly connected to the end of the square tube. Several locking grooves are opened on the outer side of the locking sleeve. The end of the limit rod is inserted into the locking groove.
[0015] Furthermore, a spring is fixedly connected between the floating seat and the electric actuator;
[0016] A locking pin is fixedly installed on the outer side of the electric actuator. The bottom of the floating seat has a through hole to avoid the shaft end of the electric actuator, and clearance openings are provided on both sides of the through hole for the locking pin to enter.
[0017] Furthermore, the lock cylinder assembly includes a mounting sleeve fixed inside the first handle, a lock cylinder rotatably connected to the inner side of the mounting sleeve, a pull rod passing through the upper end of the lock cylinder, a spiral groove being formed on the outer side of the lock cylinder housing, and a guide shaft sliding in the spiral groove being fixed on the outer side of the pull rod.
[0018] Furthermore, a drive rod is rotatably connected to the top of the pull rod, and the drive rod is slidably connected to the inside of the first handle;
[0019] The drive rod is fixedly mounted with a lever on its side, and the floating seat has a slot on its side for the lever to slide.
[0020] The advantages of this utility model are as follows: This utility model employs both electric and manual control components and lock cylinder components to unlock the lock rod assembly. This facilitates the rotation of the locking assembly by the first and second handles, thereby enabling the door lock to be opened via the lock box. The two control methods can meet the operational needs of different environments. For example, when the control component is powered off, the lock cylinder component can still be used for unlocking.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Reference Figure 1-8 As an embodiment of the present utility model, a lever-handle smart lock is disclosed. Specifically, the smart lock includes a first panel 2 configured with a first lever 1 and a second panel 4 configured with a second lever 3.
[0032] A locking rod assembly 5 is provided between the first handle 1 and the second handle 3. A main circuit board 7 with a fingerprint module 6 and a control component 8 for locking the locking rod assembly 5 are installed inside the first handle 1. A lock cylinder assembly 9 is also provided on the inner side of the first handle 1. The lock cylinder assembly 9 is connected to the control component 8.
[0033] Specifically, the first panel 2 and the second panel 4 are respectively installed on both sides of the door panel. A connector 10 passing through the door panel is connected between the first panel 2 and the second panel 4. The connector 10 is a connecting post fixed on the first panel 2. There are two connecting posts. The connecting posts are connected and fixed to the second panel 4 by bolts or other fasteners.
[0034] In use, the user can trigger the control component 8 by touching the fingerprint module 6. When the main circuit board 7 receives the correct fingerprint signal, the control component 8 opens to lock the locking rod assembly 5. At this time, the locking rod assembly 5 is in a free position. Rotating the first handle 1 will drive the locking rod assembly 5 to rotate, thereby realizing the unlocking control of the lock box. Of course, the specific structure of the fingerprint module 6 and the lock box mentioned above are all conventional methods for those skilled in the art, and will not be elaborated here.
[0035] In addition, in the event of a power outage, the lock cylinder assembly 9 can also unlock the lock rod assembly 5, thus forming two unlocking methods. The specific structure and principle will be described later, and will not be elaborated here.
[0036] In some embodiments, a secondary circuit board 31 and a battery 32 are fixedly installed inside the second handle 3. A charging interface is provided on the first handle 1 or the second handle 3 to charge the battery 32. The secondary circuit board 31 and the battery 32 are electrically connected, and the secondary circuit board 31 is electrically connected to the main circuit board 7. It should be noted that in this embodiment, the connecting wires between the secondary circuit board 31 and the main circuit board 7 can pass through the inside of the square tube 51, thus enabling an electrical connection between the main circuit board 7 and the battery 32 to meet the power supply requirements of the electrical components. The secondary circuit board 31 is also equipped with an unlocking button 33 exposed on the outside of the second handle 3. Specifically, in this embodiment, the unlocking button 33 is used to unlock the control component 8. Of course, those skilled in the art will know that the unlocking button 33 in this embodiment can also be a fingerprint unlocking module, thus meeting the unlocking requirements from both inside and outside the door.
[0037] Furthermore, in this embodiment, the locking rod assembly 5 includes a square tube 51 passing through the first handle 1 and the second handle 3. A connecting piece 52 is fixedly installed on the outer side of the square tube 51. A torsion spring 53 is fixedly connected to the inner side of the connecting piece 52 and the first handle 1. The torsion spring 53 is designed to reset after the square tube 51 is rotated, so as to ensure the convenience of rotating and resetting the first handle 1 and the second handle 3.
[0038] Based on the above embodiments, the control component 8 in this embodiment includes a fixing plate 81 installed in the first handle 1. The fixing plate 81 can be connected to the inside of the first handle 1 by fasteners such as bolts.
[0039] An electric actuator 82 is fixedly installed on the end face of the fixed plate 81. The shaft end of the electric actuator 82 is connected to a floating seat 83. A limit rod 84 is fixedly connected to the top of the floating seat 83. A locking sleeve 54 is fixedly connected to the end of the square tube 51. Several locking grooves 55 are opened on the outer side of the locking sleeve 54. The end of the limit rod 84 is inserted into the locking groove 55.
[0040] It should be noted that, in this embodiment, a spring 85 is fixedly connected between the floating seat 83 and the electric push rod 82;
[0041] A locking pin 86 is fixedly installed on the outer side of the electric actuator 82. The bottom of the floating seat 83 is provided with a through hole to avoid the shaft end of the electric actuator 82, and clearance openings 87 are provided on both sides of the through hole for the locking pin 86 to enter.
[0042] During installation, the shaft end of the electric actuator 82 is first inserted into the through hole. During this process, the locking pin 86 enters the inner side of the floating seat 83 along the clearance opening 87. Of course, in order to achieve the mechanical connection between the locking pin 86 and the floating seat 83, so that the shaft end of the electric actuator 82 can pull the floating seat 83 up and down when it extends and retracts, the electric actuator 82 needs to be rotated after installation so that the locking pin 86 and the clearance opening 87 are misaligned. In this way, the linkage between the electric actuator 82 and the floating seat 83 can be achieved.
[0043] During the unlocking process, when the main circuit board 7 or the secondary circuit board 31 receives the unlocking signal, it will control the electric push rod 82 to retract. The electric push rod 82 pulls the floating seat 83 downward, thus separating the limiting rod 84 on the floating seat 83 from the lock groove 55 at the end of the locking sleeve 54. At this time, the entire square tube 51 is in a free state, so the square tube 3 can be rotated by rotating the first handle 1 and the second handle 3. After the square tube 3 is rotated, it will drive the lock box to unlock, thus completing the door opening operation.
[0044] Furthermore, in this embodiment, the lock cylinder assembly 9 includes a mounting sleeve 91 fixed inside the first handle 1. A lock cylinder 92 is rotatably connected to the inner side of the mounting sleeve 91. A pull rod 93 passes through the upper end of the lock cylinder 92. A spiral groove 94 is formed on the outer side of the housing of the lock cylinder 92. A guide shaft 95 that slides in the spiral groove 94 is fixed on the outer side of the pull rod 93. Of course, in order to ensure the linear movement of the pull rod 93, a guide structure is provided between the pull rod 93 and the mounting sleeve 91, such as a guide bolt on the mounting sleeve 91 and a guide groove on the outer side of the pull rod 93, so as to ensure the linear movement of the pull rod 93.
[0045] Based on the above embodiments, in this embodiment, the top of the pull rod 93 is rotatably connected to a drive rod 96, and the drive rod 96 is slidably connected to the inner side of the first handle 1;
[0046] The drive rod 96 is fixedly mounted with a lever 97 on its side, and the floating seat 83 is provided with a slot 88 on its side for the lever 97 to slide. The slot 88 is used to avoid the displacement of the floating seat 83 when the electric push rod 82 is driven.
[0047] Specifically, when manual unlocking is required, insert the key into the lock cylinder 92 and rotate the lock cylinder 92. Since the pull rod 93 and the outer shell of the lock cylinder 92 are connected by a spiral groove 94 and a guide shaft 95, when the lock cylinder 92 rotates, the pull rod 93 is driven to move up and down through the spiral groove 94 and the guide shaft 95. When the pull rod 93 moves down, the floating seat 83 is pulled down by the toggle block 97. Similarly, the downward movement of the floating seat 83 can separate the limiting rod 84 and the lock groove 55 at the end of the locking sleeve 54. After that, rotating the first handle 1 or the second handle 3 can complete the unlocking.
[0048] In summary, this utility model employs both electric and manual control components 8 and lock cylinder 9 to unlock the lock rod assembly 5. This facilitates the rotational drive of the first handle 1 and the second handle 3 on the locking assembly 5, thereby enabling the door lock to be opened via the lock box. The two control methods can meet the operational needs of different environments. For example, when the control component 8 is de-energized, the lock cylinder assembly 9 can be used for unlocking. The overall structural design is simple and optimizes the convenience of traditional operation.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
