Description

Technical Field

[0001] The utility model relates to the technical field of intelligent locks, in particular to an intelligent lock with a dislocation linkage structure. Background Art

[0002] In the structural design of existing intelligent locks, two knobs are provided to respectively link the main lock control hole and the insurance control hole. The position between the two knobs is generally used to place small-sized batteries. If the battery life performance of the intelligent lock is to be enhanced, considering changing the small battery to a large battery, this will increase the center distance between the main lock control knob and the insurance control knob. Since the center distance between the main lock control hole and the insurance control hole on the lock body is fixed, such an adjustment will cause one of the knobs to be axially misaligned with its corresponding lock body control hole, conflicting with the design of the battery size adjustment in the intelligent lock. Therefore, an intelligent lock with a dislocation linkage structure is needed, which can adjust the battery specification between the two knobs without affecting the linkage of the double knobs to the main lock control hole and the insurance control hole, so as to enhance the battery life of the intelligent lock. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: Please refer to the attached Figure 1 to the attached Figure 5 , this embodiment provides an intelligent lock with a misaligned linkage structure, including a front shell 1, a rear shell 2, a knob mechanism 3 rotatably arranged on the front shell 1, a rotary docking mechanism 4 rotatably arranged on the rear shell 2, and a linkage mechanism 5 arranged between the front shell 1 and the rear shell 2. The knob mechanism 3 includes a first knob 31 and a second knob 32. The rotary docking mechanism 4 includes a first rotary member 41 and a second rotary member 42. A battery compartment 11 is provided on the front shell 1 between the first knob 31 and the second knob 32. The first knob 31 is coaxially docked with the first rotary member 41, so that the rotation of the first knob 31 drives the co-directional rotation of the first rotary member 41. The linkage mechanism 5 includes a knob gear 51, a rotary member gear 52, and a linkage gear 53. The second knob 32 is coaxially docked with the knob gear 51, and the second rotary member 42 is coaxially docked with the rotary member gear 52. The linkage gear 53 is simultaneously engaged with the knob gear 51 and the rotary member gear 52, so that the rotation of the second knob 32 drives the co-directional rotation of the second rotary member 42 through the linkage gear 53. In the intelligent lock with a misaligned linkage structure of this embodiment, a battery compartment 11 capable of supporting the installation of a large battery is provided between the first knob 31 and the second knob 32, so that the center distance between the first knob 31 and the second knob 32 is greater than the center distance between the first rotary member 41 and the second rotary member 42. Therefore, a linkage mechanism 5 is added. The linkage mechanism 5 adopts the meshing linkage of the knob gear 51 connecting the second knob 32, the rotary member gear 52 connecting the second rotary member 42, and the linkage gear 53. On the premise that the first knob 31 and the first rotary member 41 are coaxially linked and rotated, the eccentric misaligned linkage of the second knob 32 to the second rotary member 42 is realized, maintaining the matching docking of the first rotary member 41 and the second rotary member 42 to the main lock control hole and the insurance control hole of the standard lock body respectively, providing an effective structural basis for the enhanced design of the battery life of the intelligent lock.

[0023] One end of the first rotating member 41 away from the first knob 31 is provided with a first docking port 411 for docking with the main lock rotating shaft of the lock body, and one end of the second rotating member 42 away from the rotating member gear 52 is provided with a second docking port 421 for docking with the safety rotating shaft of the lock body. The shape of the first docking port 411 matches the protruding end of the main lock control shaft of the standard lock body, and torque can be transmitted by twisting the first knob 31 to drive the expansion and contraction of the main lock of the lock body. The shape of the second docking port 421 matches the protruding end of the safety control shaft of the standard lock body, and torque can be transmitted by twisting the second knob 32 to drive the expansion and contraction of the safety lock of the lock body.

[0024] The intelligent lock with a dislocation linkage structure further includes a first clamping mechanism 6 for clamping the first knob 31 and the first rotating member 41, and a second clamping mechanism 7 for clamping the second knob 32 and the knob gear 51. The first knob 31 drives the first rotating member 41 to rotate around the axis at the same angular velocity through the first clamping mechanism 6, and the second knob 32 drives the knob gear 51 to rotate around the axis at the same angular velocity through the second clamping mechanism 7. The adoption of the first clamping mechanism 6 and the second clamping mechanism 7 facilitates the assembly of the intelligent lock on the premise of not affecting the connection relationship between the knob and the rotating member.

[0025] The second clamping mechanism 7 includes a correspondingly arranged second docking groove 71 and a second docking shaft 72. The end of the second docking shaft 72 is provided with oppositely arranged torque notches 721. When the second docking shaft 72 is inserted into the second docking groove 71, the torque notches 721 abut against the opposite inner walls of the second docking groove 71 for transmitting the torque between the second knob 32 and the knob gear 51. The setting of the torque notches 721 facilitates the fitting installation of the second docking groove 71. Further, the second docking groove 71 is arranged at the bottom of the second knob 32, and the second docking shaft 72 protrudes axially on the knob gear 51. The second docking shaft 72 is hollow and has a fastening hole 722 at the end, and a screw hole 711 corresponding to the fastening hole 722 is arranged in the second docking groove 71. The connection between the second knob 32 and the knob gear 51 can be made more firm by using a screw fastening method, that is, passing a screw through the fastening hole 722 and fastening it in the screw hole 711.

[0026] The rotating member gear 52 is arranged at one end of the second rotating member 42 away from the second docking port 421, and the second rotating member 42 and the rotating member gear 52 are integrally formed, saving the production cost of parts.

[0027] The first clamping mechanism 6 includes a correspondingly arranged first docking groove 61 and a first docking block 62. The first docking block 62 and the first docking groove 61 are in a square fit for transmitting the torque between the first knob 31 and the first rotating member 41, so as to facilitate the direct rotational linkage of the first knob 32 to the first rotating member 42.

[0028] The battery compartment 11 is square-shaped. The first knob 31 and the second knob 32 are respectively located on opposite sides of the battery compartment 11 along the length direction. The setting of the battery compartment 11 is adapted to the fitting installation of existing large-capacity rechargeable batteries.
