Description

Technical Field

[0001] This utility model relates to the field of intelligent lock technology, and in particular to a reversing toggle structure. Background Technology

[0002] With the booming development of the smart home industry, smart locks, as core components for ensuring home security and improving convenience, are experiencing rapid technological iteration. In the current smart lock market, lever locks and spherical locks occupy a significant market share due to their unique structural features and application scenarios.

[0003] Lever locks, with their advantages of easy operation and stable structure, are widely used in residences, offices, and other places; while spherical locks, due to their simple design and convenient installation, are favored in interior doors and other similar applications. The normal operation of both types of locks relies on a core transmission component—the lever mechanism. This component, located inside the lock body, moves synchronously with the rotation of the lever or spherical handle. Through real-time sensing with sensors, it enables key functions such as unlocking and locking, forming a crucial foundation for the automated control of smart locks.

[0004] However, a significant technical challenge exists in existing technologies: lever locks and spherical locks differ fundamentally in their structural compatibility. Specifically, in left-opening and right-opening door scenarios, the handle orientation of a lever lock must be adjusted accordingly to accommodate different opening directions. This necessitates a specific directional adaptation structure for its lever mechanism. In contrast, spherical locks, due to their circular symmetrical structure, can be used normally regardless of whether the door opens to the left or right. Therefore, the structural design of their lever mechanism is fundamentally different from that of lever locks. This difference in structural compatibility directly results in the incompatibility of lever mechanisms adapted to lever locks and spherical locks.

[0005] This technological limitation has brought many inconveniences to lock manufacturers: on the one hand, companies need to design and produce different specifications of pull parts for two types of locks, which not only increases production costs such as mold development and production line adjustment, but also extends the product development cycle; on the other hand, in the production and inventory preparation stage, companies must simultaneously stock up on two types of pull parts to meet the assembly needs of different locks, which not only occupies a lot of warehouse space, but may also lead to the accumulation or shortage of a certain type of pull part due to fluctuations in market demand, affecting production efficiency and market response speed.

[0006] Therefore, how to overcome the structural limitations of existing lever components and develop a universal lever component that can be adapted to both lever locks and ball locks to reduce production costs and simplify the production and inventory process has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a reversing lever structure that can be adapted to lever locks or ball locks.

[0008] A reversing lever structure designed for this purpose includes a lock body, a lever component, and a torsion spring, wherein the lever component is rotatably disposed relative to the lock body; the lever component is used to connect a ball handle or a grip.

[0009] The pusher is provided with a first abutting part and a second abutting part; the first end of the torsion spring abuts and limits the first abutting part, and the second end of the torsion spring abuts and limits the second abutting part;

[0010] The lock body is provided with a first trigger and a second trigger at intervals along the rotation direction of the lever relative to the lock body;

[0011] When the lever is used to connect the handle, both the first end and the second end are located between the first trigger and the second trigger; when used as a left-opening lock body, the first end abuts against the first trigger; when used as a right-opening lock body, the second end abuts against the second trigger.

[0012] When the pusher is used to connect the ball handle, both the first end and the second end are located between the first trigger and the second trigger, with the first end abutting against the second trigger and the second end abutting against the first trigger.

[0013] Preferably, a first limiting hook is provided at the end of the first abutting part away from the pusher, and the first end is disposed between the first abutting part and the first limiting hook.

[0014] The second abutment is provided with a second limiting hook at the end away from the pusher, and the second end is disposed between the second abutment and the second limiting hook.

[0015] Preferably, the pusher is provided with a first sensing mounting position and a second sensing mounting position;

[0016] The first sensor mounting position is used to install the handle sensor;

[0017] The second sensing mounting position is used to install the ball lock sensor.

[0018] Preferably, the lock body is a rear lock body.

[0019] Compared with the prior art, the specific beneficial effects of this utility model are as follows:

[0020] Achieving full-scenario adaptability and significantly reducing overall costs: In this structure, the lever can flexibly connect to a spherical handle or lever arm. Utilizing the contact limiting between the two ends of the torsion spring and the first and second abutment parts, as well as the spacing between the first and second trigger elements on the lock body, a single structure can meet the usage requirements of a spherical lock while also adapting to different scenarios for left-opening and right-opening lever arm locks. When connected to a lever arm, the first and second ends of the torsion spring are positioned between the two trigger elements; when opening to the left, the first end abuts against the first trigger element, and when opening to the right, the second end abuts against the second trigger element. When connected to a spherical handle, the two trigger elements abut against the two ends of the torsion spring respectively. This design completely eliminates the two existing production modes for lever elements, comprehensively reducing costs and improving the utilization efficiency of production resources from mold development and production line configuration to inventory management.

[0021] Simplified operation and enhanced adaptability: Whether switching between a ball handle and a lever handle, or changing between left-opening and right-opening states of a lever handle lock, no structural modifications to the toggle mechanism are required. This is achieved solely through the contact between the torsion spring and different trigger elements. This feature makes lock assembly more convenient during production and allows for quick operation during later maintenance, handle type changes, or adjustments to the opening direction, greatly improving the product's adaptability to different usage scenarios.

[0037] See Figures 1-5 A reversing lever structure includes a lock body 10, a lever 20, and a torsion spring 30. The lever 20 is rotatably disposed relative to the lock body 10. The lever 20 is used to connect a ball handle 40 or a grip 50. The lever 20 is provided with a first abutting portion 201 and a second abutting portion 202. The first end 310 of the torsion spring 30 abuts and limits the first abutting portion 201, and the second end 320 of the torsion spring 30 abuts and limits the second abutting portion 202. The lock body 10 is provided with a first trigger 110 and a second trigger 120 spaced apart along the rotation direction of the lever 20 relative to the lock body 10.

[0038] When the lever 20 is used to connect the handle 50, the first end 310 and the second end 320 are both located between the first trigger 110 and the second trigger 120; when used as a left-opening door lock body, the first end 310 abuts against the first trigger 110; when used as a right-opening door lock body, the second end 320 abuts against the second trigger 120.

[0039] When the pusher 20 is used to connect the ball handle 40, the first end 310 and the second end 320 are both located between the first trigger 110 and the second trigger 120, the first end 310 abuts against the second trigger 120, and the second end 320 abuts against the first trigger 110.

[0040] The working principle of this utility model is as follows:

[0041] See Figure 1When the lever is connected to the handle and used as a left-opening lock body, the first end of the torsion spring abuts against the first trigger of the lock body, and the second end is located between the first and second triggers, with the first end abutting and limiting the movement of the first contact part of the lever. When the handle is rotated, the lever rotates synchronously with the handle. The first trigger constrains the first end of the torsion spring, preventing it from moving with the lever, causing the torsion spring to deform and accumulate elastic force. During this process, the first end of the torsion spring separates from the original contact part. When the handle is rotated to the unlocked position, the external force is released, and the torsion spring resets under the elastic force. The first end abuts against the first trigger again and returns to the state of contact with the first contact part. The lever returns to its initial position, completing the opening action of the left-opening door.

[0042] See Figure 2 When used as a right-opening door lock body, the second end of the torsion spring abuts against the second trigger, the first end is located between the two triggers, and the second end abuts against the second abutting part for limitation. When the handle is turned, the second trigger constrains the second end of the torsion spring so that it cannot move with the lever, causing the torsion spring to deform and accumulate elastic force. During this process, the second end of the torsion spring separates from the original abutting part. After unlocking, the torsion spring resets, causing the second end to abut against the second trigger again and re-abut against the second abutting part, the lever resets, and the right-opening door is opened.

[0043] See Figure 3 When the prying element connects to the ball handle, in the initial state, the first end of the torsion spring abuts against the second trigger, and the second end abuts against the first trigger, with the first and second ends respectively maintaining contact with the first and second abutments. When the ball handle rotates forward, the prying element drives the torsion spring to move. During this process, the second trigger blocks the first end of the torsion spring, preventing it from moving. The first end gradually separates from the first abutment, causing deformation and accumulating elastic force. The second end gradually moves away from the first trigger, but always maintains contact with the second abutment. When the external force constraint is released, the torsion spring drives the prying element to reverse and reset. When the ball handle rotates in the reverse direction, the first trigger blocks the second end of the torsion spring, causing the torsion spring to deform and accumulate elastic force. During this process, the second end separates from the second abutment, while the first end always maintains contact with the first abutment and gradually moves towards the second trigger. Regardless of whether the lock is rotated forward or backward to the unlocked position, after the external force is released, the torsion spring resets under the action of elasticity, and the separated end re-abuts against the corresponding trigger and abutment. The prying part returns to its initial state, completing the opening action of the spherical lock.

[0044] See Figure 5The first abutment portion 201 has a first limiting hook 203 at its end away from the prying member 20, and the first end 310 is positioned between the first abutment portion 201 and the first limiting hook 203. The second abutment portion 202 has a second limiting hook 204 at its end away from the prying member 20, and the second end 320 is positioned between the second abutment portion 202 and the second limiting hook 204. The first limiting hook and the first abutment portion cooperate to form a receiving space, in which the first end of the torsion spring is confined. Similarly, the second limiting hook and the second abutment portion cooperate to form a receiving space, in which the second end of the torsion spring is positioned. This structural design allows the torsion spring to be pre-installed on the prying member, achieving pre-installation integration of the torsion spring and the prying member. At the same time, the first and second limiting hooks can firmly constrain the two ends of the torsion spring to the corresponding abutment portions, effectively preventing relative displacement or even separation between the torsion spring and the prying member during rotation, assembly, or transportation. This not only ensures a stable fit between the torsion spring and the lever, guaranteeing that the torsion spring can accurately engage and limit the first and second contact parts during operation, but also simplifies the overall assembly process of the lock, improves production efficiency, and lays a good foundation for subsequent assembly with the lock body.

[0045] See Figure 5 The lever component 20 is provided with a first sensing mounting position 210 and a second sensing mounting position 220; the first sensing mounting position 210 is used to install the handle sensor; the second sensing mounting position 220 is used to install the ball lock sensor. The independent setting of the two sensing mounting positions avoids mutual interference between the handle sensor and the ball lock sensor during installation and use. It not only meets the sensing requirements when the lever component is connected to the handle and the ball handle respectively, but also further enhances the versatility of the structure. This allows the same lever component to be adapted to the installation of two different sensors without modification, simplifying component design and production processes, and providing convenience for the modular assembly of locks.

[0046] Furthermore, the handle sensor and the ball lock sensor are magnets, and a Hall sensor that senses the magnet is installed in the circuit board of the lock. The position information is transmitted through the sensing between the sensor and the magnet.

[0047] In this utility model, the lock body 10 is a rear lock body.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
