A lock body dial clutch mechanism

Abstract

This utility model discloses a lock body dial clutch mechanism, belonging to the field of door locks. It includes a power source assembly, a dial, an actuating element, and an elastic element. In this application, a dial is provided on the lock cylinder, and the housing containing the power source assembly is slidably disposed within the lock case. An actuating element is provided on the side of the housing. When the lock cylinder drives the dial to rotate, it causes the actuating element to rotate, thereby causing the actuating element to act as a lever to move the housing, ultimately disengaging the power source assembly from the transmission assembly. This ensures that the self-locking of the power source assembly does not affect the movement of the bolt. This solves the problem in the prior art where, due to the self-locking function of the drive mechanism of smart locks, the mechanical lock is unable to effectively open when the battery is dead while the door is locked.

Description

Technical Field

[0001] This utility model relates to the field of smart door locks, and in particular to a lock body dial clutch mechanism. Background Technology

[0002] A door lock is a mechanical or electromechanical safety device installed between the door leaf and the door frame to control the opening and closing of entrances and exits. Its core function is to achieve "allowing legitimate personnel and preventing unauthorized personnel" entry and exit management through physical barriers and identity verification mechanisms.

[0003] The lock body is one of the components of a lock. Lock bodies can be mainly classified into two categories based on their operating and unlocking modes: pin tumbler locks and smart locks. Each type has its own advantages and disadvantages. Smart locks, in particular, are designed using electronic technology, integrated circuits, and numerous electronic components. They are more intelligent and secure in terms of identification and security.

[0004] However, smart locks are typically battery-powered, meaning they are powered by batteries that drive a mechanism to extend / retract the lock cylinder to open and close doors and windows. To ensure security, this mechanism usually has a self-locking function. Furthermore, to ensure the smart lock can still be opened in the event of a power outage, a mechanical lock is required. However, due to the self-locking function of the mechanism, a mechanical lock is less effective at opening the door if the battery is dead while the door is locked. Utility Model Content

[0005] This utility model provides a lock body dial clutch mechanism, which can solve the problem in the prior art where the mechanical lock is difficult to open effectively when the battery is dead due to the self-locking function of the drive mechanism of the smart lock.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A lock body dial clutch mechanism, comprising:

[0008] A power source assembly, which is disposed inside the lock housing, is used to output power and drive the lock tongue to extend / retract after being transmitted through the transmission assembly;

[0009] A dial, which is fixedly mounted on the side of the lock cylinder;

[0010] A toggle element, the middle of which is hinged to the lock housing, one end of which is located on the rotation trajectory of the dial wheel, and the other end abutting against the power source assembly;

[0011] An elastic element, the elastic element being used to provide an elastic force to drive the power source assembly to reset;

[0012] When the actuating element rotates, it drives the power source assembly to move and disengage from the transmission assembly.

[0013] In one embodiment of this utility model: a guide portion is provided at the end of the dial that is away from the lock cylinder.

[0014] In one embodiment of this utility model: the actuating component includes a lever and a transition part that are fixedly connected, and the transition part is hinged to the lock housing.

[0015] In one embodiment of this utility model, the adapter is located on the side away from the dial.

[0016] In one embodiment of this utility model: the lever includes a first main body and a second main body with an integral structure, the adapter is located at the connection between the first main body and the second main body, and the end of the second main body away from the first main body is in contact with the power source assembly.

[0017] In one aspect of this utility model: the first body includes a contact surface with a curved profile.

[0018] In one embodiment of this utility model: a guide portion is provided at the end of the first body away from the second body.

[0019] In one embodiment of this utility model, the guide portion is a rounded corner structure or is inclined.

[0020] In one embodiment of this utility model: a limiting member is fixedly provided inside the lock housing, and the limiting member and the power source assembly are respectively located on both sides of the actuating member.

[0021] In one embodiment of this utility model, the elastic element is a compression spring.

[0022] The lock body dial clutch mechanism according to this utility model has at least one of the following technical effects:

[0023] In this application, a dial is provided on the lock cylinder, and the housing containing the power source component is slidably disposed within the lock case. An actuating element is provided on the side of the housing. When the lock cylinder drives the dial to rotate, it causes the actuating element to rotate, thereby causing the actuating element to act as a lever to move the housing. Ultimately, this disengages the power source component from the transmission component, ensuring that the self-locking of the power source component does not affect the movement of the bolt. This solves the problem in existing technologies where, due to the self-locking function of the drive mechanism of smart locks, the mechanical lock is unable to effectively open when the battery is dead while the door is locked.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] like Figure 1-2 As shown, it is a schematic diagram of the internal structure of the lock body, in which, Figure 1 This is a schematic diagram of the latch in its retracted state. Figure 2This is a schematic diagram of the lock tongue in the extended state. The lock body includes a lock shell 3, within which a power source assembly 1 and a transmission assembly 2 are disposed. The power source assembly 1 is disposed within the lock shell 3 and is used to output power, which is transmitted through the transmission assembly 2 to drive the lock tongue to extend / retract. The specific structure of the power source assembly 1 and the transmission assembly 2 is not limited.

[0036] Please see Figure 1-6 In one embodiment of this utility model, as an example, the power source assembly 1 includes a reduction gearbox 4 slidably disposed within the lock housing 3. The reduction gearbox 4 is provided with a power source, a worm gear 5, and a turbine 6. The power source can be an electric motor for providing power. The power source drives and connects to the worm gear 5. The turbine 6 is rotatably sleeved on a shaft. The shaft is fixedly disposed on the reduction gearbox 4 and disposed on the side of the worm gear 5, so that the turbine 6 and the worm gear 5 cooperate to form the power source assembly 1.

[0037] Please see Figure 1-6 In one embodiment of this utility model, the transmission assembly 2 may include several gear structures. The first gear 7 is used to cooperate with the power source assembly 1 to transmit power. Specifically, a drive gear can be coaxially mounted on the turbine 6, and the first gear 7 includes two coaxial gear structures, namely gear one and gear two. Gear one meshes with the drive gear at the turbine 6, and gear two meshes with other subsequent gear structures to transmit power.

[0038] like Figure 2-7 As shown in the figure, the present invention provides a lock body lever 8 clutch mechanism, including a power source assembly 1, a lever 8, a lever element 9, and an elastic element 10. The power source assembly 1 includes a housing 4, which is slidably disposed within the lock housing 3. The specific form in which the housing 4 is slidably disposed is not limited. As an example, a roughly U-shaped sliding frame 11 is fixedly disposed at one end of the housing 4, and a corresponding slide rail structure can be provided on the lock housing 3 for cooperation.

[0039] Please see Figure 2-7 In one embodiment of this utility model, the dial 8 is fixedly disposed on the side of the lock cylinder; the middle part of the actuating member 9 is hinged to the lock housing 3, one end of the actuating member 9 is located on the rotation trajectory of the dial 8, and the other end abuts against the power source assembly 1; the elastic member 10 is used to provide elastic force to drive the power source assembly 1 to reset. The elastic member 10 can be a compression spring, in which case the elastic member 10 and the actuating member 9 should be located on opposite sides of the housing 4. The elastic member 10 can also be a tension spring, in which case the elastic member 10 and the actuating member 9 should be located on the same side of the housing 4. Similarly, the elastic member 10 can also be other structures capable of providing elastic force, without limitation.

[0040] Please see Figure 2-7 Under normal circumstances, when the mechanical key does not drive the lock cylinder to rotate, the dial 8 and the actuating element 9 are not in contact (e.g., Figure 3 At this time, under the action of the elastic element 10, the power source assembly 1 and the transmission assembly 2 cooperate, enabling the lock tongue to be locked and unlocked by the power source assembly 1; that is, the drive gear meshes with the gear 1, thereby realizing normal power transmission. When the lock cylinder is driven to rotate by the key, the rotation of the lock cylinder drives the dial wheel 8 to rotate. When the dial wheel 8 rotates to the actuating element 9, it causes the actuating element 9 to rotate around the hinge position, so that the actuating element 9 acts as a lever, causing the housing 4 to overcome the elastic force of the elastic element 10 and move to the left (only by the attached...). Figure 4 (As an example), this causes the power source assembly 1 to disengage from the transmission assembly 2. Specifically, the housing 4 drives the power source, worm gear 6, and worm 5 to move to the left, thereby disengaging the drive gear from gear 1. At this point, the force of the motor is blocked, preventing it from driving the lock body to lock and unlock, thus eliminating the self-locking effect of the power source assembly 1 on the door lock. As the lock cylinder continues to rotate, it can drive the bolt to retract, unlocking the door.

[0041] Please see Figure 2-7 In one embodiment of this utility model, a guide portion is provided at the end of the dial 8 away from the lock cylinder. The guide portion can be configured as a chamfered structure or an arc structure on both sides of the end of the dial 8, which can play a guiding role when in contact with the actuating member 9, so as to facilitate the movement of the actuating member 9.

[0042] Please see Figure 2-7 In one embodiment of this utility model, the actuating member 9 may include an integrally fixedly connected lever and a connecting part. The connecting part may be configured as a plate-like structure and may be located on the side away from the lever 8. The connecting part is used for hinged connection with the lock housing 3. Specifically, a shaft may be provided on the lock housing 3 so that the connecting part can be rotatably sleeved on the shaft to achieve a hinged connection between the two.

[0043] Please see Figure 2-7 In one embodiment of this utility model, the lever may include a first body and a second body of integral structure. The adapter is located at the connection between the first body and the second body. The end of the second body away from the first body is in contact with the power source assembly 1. A notch may be formed on one side of the end of the second body near the housing 4 to facilitate better contact and engagement with the housing 4 (e.g., Figure 5 ).

[0044] Please see Figure 2-7In one embodiment of this utility model, the side of the first body near the dial wheel 8 includes a curved contact surface for better engagement with the dial wheel 8. The curved profile may include a first arc profile and a second arc profile. The first arc profile is located at the upper end of the first body and is used to contact the dial wheel 8 in the first stage, causing the dial wheel 8 to drive the actuating member 9 to rotate. The second arc profile may be an arc shape and located at the lower end of the first body (using only the attached diagram as an example), and is used to engage with the dial wheel 8 in the second stage, so that the actuating member 9 is in the rotated position, ensuring the disengagement of the power source assembly 1 from the transmission assembly 2.

[0045] Please see Figure 2-7 In one embodiment of this utility model, a guide portion is provided at the end of the first body away from the second body. The guide portion can be a rounded structure or an inclined structure, or it can be an arc-shaped structure, so that when the dial 8 rotates to the end of the actuating member 9 and contacts the actuating member 9, it can more conveniently cause the actuating member 9 to move.

[0046] Please see Figure 2-5 In one embodiment of this utility model, a limiting member 12 may be fixedly disposed inside the lock housing 3. The limiting member 12 and the power source assembly 1 are respectively located on both sides of the actuating member 9. The limiting member 12 may be a columnar structure or a block structure fixedly disposed on the housing, used to limit the extreme position of the rightward movement of the housing 4. It may also be used to limit the position of the actuating member 9.

[0047] The working principle of this utility model:

[0048] The relevant structures of the power source component 1 are set on the housing 4. Specifically, the shaft of the turbine 6 is connected to the housing 4; the shaft of the transmission component 2 is connected to the lock housing 3. Specifically, the shaft of the first gear 7 and other structures in the transmission component 2 are connected to the lock housing 3. A notch can be provided at the bottom of the housing 4 to allow passage for the relevant shaft structures of the power component. Thus, when the lock cylinder rotates, the dial 8 rotates accordingly, which in turn drives the actuating element 9 to rotate, exerting a lever effect, and thus moving the housing 4. This causes the power source component 1 to disengage from the transmission component 2. Specifically, the driving gear coaxial with the turbine 6 disengages from gear one in the driven component, ensuring that the self-locking of the power component does not affect the extension / retraction of the bolt. That is, the lock cylinder can be smoothly rotated with the key, driving the bolt to lock and unlock the lock. The unlocking process by the lock cylinder driving the bolt is the same as that of existing mechanical lock structures and will not be described in detail here. The lock cylinder equipped with the dial 8 can be of the same structure as the existing mechanical lock cylinder used for inserting mechanical keys, or it can be configured with two holes, forming two separate structures; there are no restrictions here.
