Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a power mechanism for a smart lock. Background Technology

[0002] In today's rapidly developing technological landscape, smart home products, especially smart locks, are increasingly becoming standard equipment in modern homes. Smart locks, with their convenient unlocking methods such as fingerprint recognition, password input, card swiping, and remote control via mobile app, have greatly changed people's traditional lock-using habits, bringing numerous conveniences to daily life, and their market demand continues to rise.

[0003] Currently, the working principle of smart locks is generally as follows: after receiving a signal input, a power mechanism connected to a fixed base drives a square shaft inside a rotating base, which in turn drives the lock body, ultimately achieving automatic unlocking. However, in practical applications, existing smart lock power mechanisms have revealed some significant shortcomings. Although the required rotation angle of the rotating base is small, the assembly process of the drive structure is extremely complex. This not only leads to low production assembly efficiency and increased production costs, but the complex assembly process is also prone to assembly errors, affecting the overall quality and stability of the product.

[0004] In view of the problems existing in the above-mentioned technologies, the development of a stable and simple-to-assemble power mechanism is of great practical significance for the field of smart locks. Utility Model Content

[0005] The purpose of this utility model is to provide a power mechanism for a smart lock, addressing the shortcomings and deficiencies of existing technologies.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The power mechanism of the smart lock described in this utility model includes a fixed base, a rotating base rotatably connected to the fixed base, and a rotating mechanism fixed to the fixed base; the rotating mechanism is used to drive the rotating base to rotate.

[0008] The rotating mechanism includes a connecting rod, a linear module, and a slide block slidably connected to a fixed base; one end of the connecting rod is hinged to the slide block; a limiting ring is provided on the rotating base; a positioning hole is provided at the eccentric position of the limiting ring; a rotating shaft matching the positioning hole is fixed on the connecting rod; the rotating shaft is inserted into the positioning hole; the surface of the connecting rod is attached to the surface of the limiting ring facing the fixed base.

[0009] Furthermore, the slide block is composed of a sleeve and a slider; the fixed base is provided with a guide rail that is slidably connected to the slider; the linear module is connected with an insert shaft; the insert shaft matches the inner hole of the sleeve; the insert shaft is inserted into the sleeve from top to bottom.

[0010] Furthermore, a support column is provided at the bottom of the connecting rod at a position directly opposite the pivot; the end of the support column is attached to the surface of the fixed base; the end of the support column is spherical.

[0011] Furthermore, the linear module includes a lead screw, a gearbox, and a motor; the motor is fixed on a mounting base; the two ends of the gearbox are respectively fixed to the motor output end and one end of the lead screw; a lead screw nut is threaded onto the lead screw; the insert shaft is fixed on the lead screw nut; the lead screw and the motor are arranged parallel to each other.

[0012] Furthermore, the connecting rod is L-shaped; a reinforcing rib is provided between the two inner surfaces of the connecting rod.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows: After the rotating seat is snapped onto the outer surface of the fixed seat by the snap ring, the axial direction limitation of the rotating seat on the fixed seat is formed by the support of the limiting ring by the connecting rod and the snap ring being clamped onto the outer surface of the fixed seat, so that the rotating seat and the fixed seat are rotatably connected, improving assembly efficiency; the linear structure combined with the connecting rod structure provides stable thrust, and the linear mechanism and the rotating seat only need to be connected by the connecting rod structure; it can be achieved by inserting the rotating shaft into the positioning hole, that is, the assembly of the rotating seat and the connecting rod can be achieved at the same time as the linear module and the rotating seat are connected to the fixed seat; making the assembly of the power mechanism of the entire lock simpler.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, the power mechanism of the smart lock of this utility model includes a fixed base 9, a rotating base 1 rotatably connected to the fixed base 9, and a rotating mechanism fixed to the fixed base 9; the rotating mechanism is used to drive the rotating base 1 to rotate; the fixed base 9 is part of the lock panel; the rotating base 1 and the fixed base 9 are rotatably connected by a snap ring, which is not fundamentally different from the prior art, so it will not be described in detail here.

[0025] The rotating mechanism includes a connecting rod 8, a linear module, and a slide block 2 slidably connected to a fixed base 9; one end of the connecting rod 8 is hinged to the slide block 2; a limiting ring 101 is provided on the rotating base 1; a positioning hole 10101 is provided at the eccentric position of the limiting ring 101; a rotating shaft 801 matching the positioning hole 10101 is fixed on the connecting rod 8; the rotating shaft 801 is inserted into the positioning hole 10101; the surface of the connecting rod 8 is in contact with the surface of the limiting ring 101 facing the fixed base 9;

[0026] The linear module drives one end of the connecting rod 8 to move, which in turn causes the connecting rod 8 to push the rotating seat 1 to rotate.

[0027] After the rotating seat 1 is snapped onto the outer surface of the fixed seat 9 by the snap ring, the limiting ring 101 is supported by the connecting rod 8 and the snap ring is snapped onto the outer surface of the fixed seat 9, thus forming an axial direction limit on the fixed seat 9, so that the rotating seat 1 and the fixed seat 9 are rotatably connected, improving assembly efficiency.

[0028] The linear structure combined with the linkage structure provides stable thrust. Moreover, the linear mechanism and the rotating seat 1 are connected only by the linkage 8. This can be achieved by inserting the rotating shaft 801 into the positioning hole 10101. In other words, the assembly of the rotating seat 1 and the linkage 8 can be achieved at the same time as the linear module and the rotating seat 1 are connected to the fixed seat 9, making the assembly of the power mechanism of the entire lock simpler.

[0029] In a preferred embodiment of this utility model, the slide block 2 is composed of a sleeve 201 and a slider 202; the fixed base 9 is provided with a guide rail 901 that is slidably connected to the slider 202; the linear module is connected with an insert shaft 601; the insert shaft 601 matches the inner hole of the sleeve 201; the insert shaft 601 is inserted into the sleeve 201 from top to bottom;

[0030] The sleeve 201 and the slider 202 are integrally formed. The sleeve 201 is connected to the insert shaft 601 by a direct insertion method. The sleeve 201 and the insert shaft 601 can be docked and assembled by positioning the slide 2 on the guide rail 901 and the linear module on the fixed seat 9, which simplifies the assembly structure. The linear module drives the insert shaft 601 to move, realizing the sliding of the slide 2 on the guide rail 901.

[0031] In a preferred embodiment of this utility model, a support column 802 is provided at the bottom of the connecting rod 8, which is directly opposite the rotating shaft 801; the end of the support column 802 is attached to the surface of the fixing seat 9; the end of the support column 802 is spherical, and the connecting rod 8 is supported by the support column 802 to prevent the rotating shaft 801 from coming out of the positioning hole 10101.

[0032] In a preferred embodiment of this utility model, the linear module includes a lead screw 3, a reduction gearbox 4, and a motor 5; the motor 5 is fixed on a mounting base 9; the two ends of the reduction gearbox 4 are respectively fixed to the output end of the motor 5 and one end of the lead screw 3; a lead screw nut 6 is threaded onto the lead screw 3; the insert shaft 601 is fixed to the lead screw nut 6; the lead screw 3 and the motor 5 are arranged parallel to each other; the guide rail 901 and the lead screw 3 are also arranged parallel to each other.

[0033] Motor 5 is fixed to mounting base 9 via motor mounting base 7; lead screw 3 is threadedly connected to motor mounting base 7; after motor 5 and lead screw 3 are connected by reduction gearbox 4, motor 5 and lead screw 3 are parallel to each other, making the width of the linear module smaller; motor 5 drives lead screw 3 to rotate via reduction gearbox 4, and lead screw nut 6 moves along the length direction of guide rail 901 because the insert shaft 601 is sleeved by sleeve 201; after lead screw nut 6 is limited by slide 2, it cannot rotate.

[0034] In a preferred embodiment of this utility model, the connecting rod 8 is in the shape of an "L"; a reinforcing rib 803 is provided between the two inner surfaces of the connecting rod 8; the "L" shaped connecting rod 8 can avoid the position of the rotating seat 1, and the reinforcing rib 801 can ensure the strength of the connecting rod 8.

[0035] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
