Description

Technical Field

[0001] The present invention relates to the technical field of smart locks, and in particular to a smart lock cat's eye lever structure and a smart lock. Background Art

[0002] like Figure 1 and Figure 2 As shown, at present, there are usually two concave points 2 under the cat's eye slider 1, and a return spring 3 and a marble 4 are installed in the cylindrical hole of the lock shell. When the cat's eye slider 1 moves back and forth, the marble 4 will move up and down and stay in the concave point 2, so that the cat's eye remains stationary under no external force, thereby achieving the "open" and "close" functions of the cat's eye slider 1.

[0003] With this prior art solution, during assembly, the marble 4, under the action of the return spring 3, presses against the cat's eye slider 1, causing the slider 1 to tilt and making installation inconvenient. Furthermore, when the cat's eye slider 1 is moved, the force applied to the spring 3 is on one side of the moving point, resulting in uneven force, unsmooth sliding, and a poor feel. Summary of the Invention

[0004] The main purpose of the present invention is to provide a smart lock cat's eye lever structure and a smart lock, aiming to reduce assembly difficulty and production costs.

[0005] To achieve the above-mentioned object, the present invention provides a smart lock cat's eye lever structure, the smart lock comprising a face shell, a face cover arranged on the face shell, and a rotating shaft arranged in the face shell, the smart lock cat's eye lever structure comprising a cat's eye shift block, a cat's eye cam, and a reset spring, the cat's eye shift block being rotatably arranged on the face cover, the upper end of the cat's eye cam being clamped in the face shell and being able to move up and down relative to the face shell under the drive of the cat's eye shift block, the reset spring being sleeved on the cat's eye cam, the rotating shaft being provided with a groove corresponding to the cat's eye cam, the bottom of the cat's eye shift block being in contact with the top of the cat's eye cam;

[0006] When the cat's eye cam rotates 90 degrees from the initial position, the cat's eye cam is driven to move downward, so that the cat's eye cam is stuck in the groove of the rotating shaft, thereby limiting the movement of the rotating shaft;

[0007] When the cat's eye cam rotates 90 degrees, the cat's eye cam moves upward to return to the initial position under the action of the return spring, and the cat's eye cam is separated from the groove of the rotating shaft, thereby canceling the restriction on the rotating shaft.

[0008] A further technical solution of the present invention is that a cam shift point is symmetrically arranged in the middle of the cat's eye shift block, two shift blocks are spaced apart on the top of the cat's eye cam, the cam shift point contacts the corresponding shift block, and the side of the shift block that contacts the cam shift point is an inclined surface.

[0009] A further technical solution of the present invention is that two protrusions are symmetrically provided on the outer periphery of the upper end of the cat's eye cam, and a card slot corresponding to the protrusions is provided in the surface shell.

[0010] To achieve the above-mentioned purpose, the present invention also proposes a smart lock, which includes the smart lock cat's eye lever structure as described above.

[0011] The beneficial effects of the smart lock cat's eye lever structure and the smart lock of the present invention are: through the above technical scheme, the smart lock cat's eye lever structure includes a cat's eye block, a cat's eye cam and a reset spring, the cat's eye block is rotatably set on the face cover, the upper end of the cat's eye cam is clamped in the face shell, and can move up and down relative to the face shell under the drive of the cat's eye block, the reset spring is sleeved on the cat's eye cam, and a groove corresponding to the cat's eye cam is provided on the rotating shaft, the bottom of the cat's eye block contacts the top of the cat's eye cam, compared with the prior art, there is no need to set two recessed points under the cat's eye slider, nor is there a need to install a reset spring and marbles in the cylindrical hole of the lock shell, so that its assembly is simpler and more convenient than the prior art, and when the cat's eye block is rotated, the force is balanced, the sliding is smooth, and the hand feel is good.

[0023] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] Considering that when assembling the current cat's eye slider, the marble will press against the cat's eye slider under the action of the return spring, causing the cat's eye module to tilt, making installation inconvenient, and when the cat's eye slider is moved, the force point of the spring is on one side of the moving point of the cat's eye slider, resulting in uneven force, unsmooth sliding, and poor hand feel. Therefore, the present invention proposes a solution.

[0028] Please refer to Figures 3 to 10 The present invention proposes a smart lock cat's eye lever structure. In a preferred embodiment of the smart lock cat's eye lever structure of the present invention, the smart lock includes a face shell 1, a face cover 2 covered on the face shell 1 and a rotating shaft 3 arranged in the face shell 1. The smart lock cat's eye lever structure includes a cat's eye dial block 4, a cat's eye cam 5 and a reset spring 6. The cat's eye dial block 4 is rotatably arranged on the face cover 2, and the upper end of the cat's eye cam 5 is clamped in the face shell 1 and can move up and down relative to the face shell 1 under the drive of the cat's eye dial block 4. The reset spring 6 is sleeved on the cat's eye cam 5, and a groove 7 corresponding to the cat's eye cam 5 is provided on the rotating shaft 3. The bottom of the cat's eye dial block 4 is in contact with the top of the cat's eye cam 5.

[0029] When the cat's eye cam 5 rotates 90 degrees from the initial position, the cat's eye cam 5 is driven to move downward, so that the cat's eye cam 5 is stuck in the groove 7 of the rotating shaft 3, limiting the movement of the rotating shaft 3, thereby achieving the purpose of preventing the cat's eye from moving.

[0030] When the cat's eye cam 5 rotates 90°, the cat's eye cam 5 moves upward to return to the initial position under the action of the return spring 6, and the cat's eye cam 5 disengages from the groove 7 of the rotating shaft 3, canceling the restriction on the rotating shaft 3, and the rotating shaft 3 can rotate normally.

[0031] Specifically, in this embodiment, the middle part of the cat's eye dial block 4 is symmetrically provided with a cam dial point 8, and two dial blocks 9 are spaced apart at the top of the cat's eye cam 5. The cam dial point 8 is in contact with the corresponding dial block 9, and the side of the dial block 9 that is in contact with the cam dial point 8 is a slope.

[0032] In this embodiment, the surface where the shift block 9 contacts the cam shift point 8 is set as an inclined surface. When the cat's eye shift block 4 is rotated, the cam shift point 8 on the cat's eye shift block 4 acts on the corresponding inclined surface of the shift block 9. Under the action of the component force, the cat's eye cam 5 moves downward and is stuck in the groove 7 of the rotating shaft 3, thereby limiting the movement of the rotating shaft 3.

[0033] Furthermore, in this embodiment, two protrusions 10 are symmetrically provided on the outer periphery of the upper end of the cat's eye cam 5 , and a slot 11 corresponding to the protrusions 10 is provided in the face shell 1 .

[0034] In this embodiment, two protrusions 10 are symmetrically arranged on the outer periphery of the upper end of the cat's eye cam 5, and a slot 11 corresponding to the protrusion 10 is arranged in the face shell 1. The two protrusions 10 are clamped in the corresponding slot 11, so that the cat's eye cam 5 can only move up and down in the face shell 1, thereby improving the stability and reliability of the entire smart lock cat's eye lever structure.

[0035] The beneficial effect of the smart lock cat's eye lever structure of the present invention is: through the above technical solution, the smart lock cat's eye lever structure includes a cat's eye block, a cat's eye cam and a reset spring, the cat's eye block is rotatably set on the face cover, the upper end of the cat's eye cam is clamped in the face shell, and can move up and down relative to the face shell under the drive of the cat's eye block, the reset spring is sleeved on the cat's eye cam, and a groove corresponding to the cat's eye cam is provided on the rotating shaft, the bottom of the cat's eye block contacts the top of the cat's eye cam, compared with the prior art, there is no need to set two recessed points under the cat's eye slider, nor is there any need to install a reset spring and marbles in the cylindrical hole of the lock shell, so that its assembly is simpler and more convenient than the prior art, and when the cat's eye block is rotated, the force is balanced, the sliding is smooth, and the hand feel is good.

[0036] To achieve the above-mentioned purpose, the present invention also proposes a smart lock, which includes the smart lock cat's eye lever structure as described in the above embodiment. The structure and working principle of the smart lock cat's eye lever structure have been explained in detail above and will not be repeated here.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
