Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, and in particular relates to a fully automatic lock body flip tongue silent pop-out structure. Background Technology

[0002] Compared to existing key-operated door locks, smart locks are becoming increasingly popular in the market due to their ease of use.

[0003] Due to the internal spring structure design, the existing smart door lock's flip-top latch remains in the pop-out state after the door is opened. However, since the back of the flip-top latch does not make a hard contact, the pop-out latch impacts the inner wall of the door frame when the door is closed again, generating significant noise. This noise is relatively harsh. To address this issue, this solution proposes a silent pop-out structure for noise reduction of the flip-top latch in fully automatic lock bodies. Utility Model Content

[0004] This utility model provides a silent pop-out structure for a fully automatic lock body flip-top tongue. This structure uses a flip-top tongue to drive a gear disc, which in turn pulls a connecting rod backward. This compresses a spring between the flip-top tongue slider and the inner wall of the flip-top tongue limiting cavity, creating a rearward clearance for the flip-top tongue body. When the door is opened, the flip-top tongue slider retracts, causing the flip-top tongue body to lose its forward return force, thereby eliminating the noise caused by the flip-top tongue body impacting the door frame when the door is opened. In summary, this solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a fully automatic lock body flip tongue silent pop-out structure, including a geared motor installed inside the lock shell, a flip tongue limiting cavity, a transmission gear disk meshing with the gear at the output end of the geared motor, a flip tongue driving gear disk meshing with the transmission gear disk, a flip tongue slider with a connecting rod, and a flip tongue body slidably installed in the flip tongue limiting cavity.

[0007] The rear side of the flip tongue body is provided with an opening groove for the flip tongue slider to be inserted and limited, and an arc-shaped protrusion is provided on the front side of the opening groove; the front end of the flip tongue slider is provided with an arc-shaped limiting groove corresponding to the arc-shaped protrusion.

[0008] A spring is fitted on the connecting rod; after unlocking, the rotating tongue drives the gear disk to pull the connecting rod backward, so that the spring is compressed between the rotating tongue slider and the inner wall of the rotating tongue limiting cavity, so that a backward accommodation gap is generated behind the rotating tongue body.

[0009] Furthermore, the two inner sidewalls of the flip tongue limiting cavity are provided with guide rails that are consistent with the traveling direction of the flip tongue body, and the two sides of the flip tongue body are provided with sliding limiting grooves that match the guide rails.

[0010] Furthermore, the rear side of the flip tongue limiting cavity is provided with a hole for the connecting rod to pass through, and the front side is provided with a locking hole for the flip tongue body to pop out and retract.

[0011] Furthermore, the end of the connecting rod is provided with an L-shaped transmission surface that corresponds to and engages with the gear transmission protrusion on the upper part of the flip tongue drive gear disk. Under the drive teeth on the outer periphery of the flip tongue drive gear disk being driven by the transmission teeth on the outer periphery of the transmission gear disk, the gear transmission protrusion drives the L-shaped transmission surface to move forward or backward. The flip tongue slider provides a backward accommodation distance for the flip tongue slider or rigidly resists the flip tongue slider to achieve locking.

[0012] The present invention has the following advantages over the prior art:

[0013] (1) Low noise: The flip tongue drives the gear plate to pull the connecting rod backward, so that the spring is compressed between the flip tongue slider and the inner wall of the flip tongue limiting cavity, so that the flip tongue body has a backward accommodation gap; when the door is opened, the flip tongue slider can be moved backward, so that the flip tongue body loses the elastic force to return to the forward position, thereby eliminating the noise of the flip tongue body impacting the door frame when the door is opened.

[0014] (2) Ingenious structure: The structure includes a geared motor installed inside the lock housing, a flip tongue limiting cavity, a transmission gear disk meshing with the gear at the output end of the geared motor, a flip tongue drive gear disk meshing with the transmission gear disk, a flip tongue slider with a connecting rod, and a flip tongue body slidably installed in the flip tongue limiting cavity; the rear side of the flip tongue body is provided with an opening groove for the flip tongue slider to be inserted and limited, and an arc-shaped protrusion is provided on the front side of the opening groove; the front end of the flip tongue slider is provided with an arc-shaped limiting groove corresponding to the arc-shaped protrusion; a spring is sleeved on the connecting rod; the structure is ingeniously designed and convenient for market promotion and use.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[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, and not all embodiments. 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 protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "inner", "rear", "front", "rear", "inner wall", "upper", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-11 As shown, this utility model discloses a fully automatic lock body flip tongue silent pop-out structure for smart door locks, including a reduction motor 6 installed inside the lock shell 7, a flip tongue limiting cavity 71, a transmission gear disk 4 meshing with the output gear of the reduction motor 6, a flip tongue driving gear disk 2 meshing with the transmission gear disk 4, a flip tongue slider 1 with a connecting rod 13, and a flip tongue body 5 slidably installed in the flip tongue limiting cavity 71.

[0033] like Figure 1 As shown, the geared motor 6 in this embodiment has a housing and a brake with a locking function. The output end of the geared motor 6 is provided with a gear that meshes with the transmission gear disk 4. The geared motor 6 adopts the model used in smart door locks, which is existing technology. Its structure and principle will not be described in detail in this solution.

[0034] The rear side of the flip-tongue body 5 is provided with an opening groove 53 for the flip-tongue slider 1 to be inserted and limited. An arc-shaped protrusion 51 is provided in front of the opening groove 53. The front end of the flip-tongue slider 1 is provided with an arc-shaped limiting groove 11 corresponding to the arc-shaped protrusion 51. The opening groove 53 allows the flip-tongue slider 1 to be inserted and allows the flip-tongue slider 1 to move back and forth under the limitation of the opening limiting groove 11. When the flip-tongue slider 1 moves forward and touches, the arc-shaped protrusion 51 fits with the arc-shaped limiting groove 11, which allows the flip-tongue body 5 to push forward and protrude from the lock hole position. This is the action after locking the door.

[0035] A spring 3 is fitted on the connecting rod 13; after unlocking, the flip tongue drives the gear disk 2 to pull the connecting rod 13 backward, so that the spring 3 is compressed between the flip tongue slider 1 and the inner wall of the flip tongue limiting cavity 71, so that a backward accommodation gap is generated behind the flip tongue body 5, and the accommodation gap is just enough to allow the flip tongue body 5 to be accommodated in the flip tongue limiting cavity 71.

[0036] The inner walls of the flip tongue limiting cavity 71 are provided with guide rails 72 that are consistent with the travel direction of the flip tongue body 5, and the two sides of the flip tongue body 5 are provided with sliding limiting grooves 52 that match the guide rails 72, so that the flip tongue body 5 can move stably.

[0037] The rear side of the flip tongue limiting cavity 71 has a hole for the connecting rod 13 to pass through, and the front side has a lock hole for the flip tongue body 5 to pop out and retract.

[0038] The connecting rod 13 has an L-shaped transmission surface 12 at its end that corresponds to the gear transmission protrusion 22 on the upper part of the flip tongue drive gear disk 2. When the drive teeth 21 on the outer periphery of the flip tongue drive gear disk 2 are driven by the transmission teeth 41 on the outer periphery of the transmission gear disk 4, the gear transmission protrusion 22 drives the L-shaped transmission surface 12 to move forward or backward. The flip tongue slider 1 provides a backward accommodation distance for the flip tongue slider 1 or rigidly resists the flip tongue slider 1 to achieve locking.

[0039] The working principle of this fully automatic lock body flip-type silent ejection mechanism is as follows:

[0040] When the door is opened, the reduction motor 6 drives the transmission gear disk 4, and the transmission gear 41 drives the drive gear 21 to rotate the flip tongue drive gear disk 2. The gear transmission protrusion 22 contacts the L-shaped transmission surface 12, causing the flip tongue slider 1 to retract. After the flip tongue slider 1 retracts, it compresses the spring 3. At this time, when a person pulls open the door, the flip tongue body 5 flips and retracts. The flipping and retraction is free for the flip tongue body 5, which is an existing structure and will not be described in detail in this embodiment. When the door is open, since the flip tongue slider 1 is in the retracted state, the flip tongue body 55 loses the elasticity of its extension, so the flip tongue body 5 will not impact the door frame and produce noise, thereby eliminating the noise of the flip tongue impacting the door frame when the door is opened. After the door is opened, The geared motor 6 rotates, driving the transmission gear disk 4. The transmission gear disk 4 drives the flip tongue drive gear disk 2 to return to its original position. The flip tongue drive gear disk 2 drives the flip tongue slider 1 to return to its original position. The compression spring 3 extends, and the elastic force is transmitted to the arc-shaped protrusion 51 through the arc-shaped limiting groove 11. The flip tongue body 5 slowly extends (not spring-loaded) and returns to its original position. The silent pop-up structure of the flip tongue in this fully automatic lock body makes the flip tongue slider 1 retract when the door is opened, so that the flip tongue body 5 loses the elastic force to return to its original position, thereby eliminating the noise of the flip tongue body 5 impacting the door frame when the door is opened. In addition, the geared motor 6 drives the main lock tongue back while driving the flip tongue slider 1 back through the transmission mechanism.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
