[0035] like Figure 1-4 As shown, an embodiment of this utility model provides a knob positioning structure, which mainly includes a middle frame body 1 and a knob switch 2. A circular groove 3 is provided on the front of the middle frame body 1, and several locking grooves 4 are formed on the circular groove 3. A positioning component 5 is securely installed on the back of the knob switch 2, and a spring-loaded positioning element 6 is provided at the front end of the positioning component 5. The positioning element 6 is aligned with the circular groove 3 and pre-compressed against the circular groove 3. When the knob switch 2 is rotated, the positioning element 6 can pop out and lock into the locking grooves 4, thus positioning the knob switch 2. The knob positioning structure can be applied to smart door locks. Positioning is achieved by setting the spring-loaded positioning element 6 and the locking grooves 4. When the positioning element 6 falls into the locking groove 4, it indicates that the knob switch 2 has been rotated to the correct position, providing a good tactile feedback. Furthermore, when the knob switch 2 is rotated, the positioning element 6 and the circular groove 3 generate a certain amount of damping, which improves the user experience.

[0036] Specifically, in this embodiment, the main body 1 of the middle frame has a cuboid shell structure. A first mounting seat 7 is provided on the front and at its lower end of the main body 1. The first mounting seat 7 is a hole seat structure, and a drive shaft 8 is rotatably mounted on the first mounting seat 7. The rear end of the drive shaft 8 is connected to the lock cylinder structure to drive the lock tongue, thereby performing unlocking and locking operations. That is, rotating the drive shaft 8 in the forward direction can realize the unlocking action, and rotating the drive shaft 8 in the reverse direction can realize the locking action. In this embodiment, a circular groove 3 is provided on the front of the main body 1. The circular groove 3 is coaxially arranged with the mounting seat, and several locking grooves 4 are formed on the circular groove 3. The cross-section of the circular groove 3 is U-shaped, that is, the circular groove 3 is annularly arranged on the outside of the mounting seat. The circular groove 3 can guide the positioning member 6 to slide in the circular groove 3. When the positioning member 6 slides in the circular groove 3, the knob switch 2 can produce a significant damping feeling due to the friction. Four locking grooves 4 are evenly arranged in a circle within the circular slide groove 3, and these grooves 4 are arranged along two axes of the main frame 1, which pass through the center of the first mounting base 7. The locking grooves 4 are semi-circular grooves used to position the positioning element 6. When the positioning element 6 is engaged in the locking groove 4, the rotational resistance of the rotary switch 2 increases significantly, providing tactile feedback that the rotary switch 2 has reached the predetermined position, thus achieving the rotational positioning of the rotary switch 2. It should be noted that in some embodiments, the circular slide groove 3 can also be set as a V-shaped groove or a rectangular groove, as long as it allows the positioning element 6 to fall into the circular slide groove 3, thus enabling the circular slide groove 3 to slide and guide the positioning element 6.

[0037] Furthermore, in this embodiment, the rotary switch 2 has a disc-shaped structure, with an operating part 9 protruding from its front. Driving the operating part 9 to rotate enables the rotary switch 2 to rotate. A mounting hole 10 is provided on the back of the rotary switch 2. One end of the drive shaft 8 is inserted into the mounting hole 10 for installation, and driving the rotary switch 2 allows the drive shaft 8 to rotate. Specifically, the front end of the drive shaft 8 is a polygonal cylindrical insertion part 11, and the mounting hole 10 is a corresponding polygonal blind hole. The mounting hole 10 extends into the interior of the operating part 9, and the insertion part 11 is inserted into the blind hole for installation. By connecting the drive shaft 8 to the mounting hole 10, driving the rotary switch 2 to rotate synchronously drives the drive shaft 8, thereby achieving a switch and lock mechanism. In order to securely connect the rotary switch 2 and the drive shaft 8, a first through hole 12 is provided on the front end face of the drive shaft 8. The first through hole 12 passes through the drive shaft 8. A threaded hole 13 is provided at the bottom of the mounting hole 10. The threaded hole 13 does not penetrate the operating part 9. The screw passes through the first through hole 12 and is fastened to the threaded hole 13, thereby securing the rotary switch 2 to the drive shaft 8.

[0038] Furthermore, in this embodiment, a second mounting base 14 is also provided on the back of the rotary switch 2. A positioning component 5 is securely installed in the second mounting base 14, and a spring-loaded positioning element 6 is provided at the front end of the positioning component 5. The positioning element 6 is aligned with the circular slide groove 3 and is pre-compressed against the circular slide groove 3. When the rotary switch 2 is rotated, the positioning element 6 can pop out and engage with the locking groove 4. The positioning element 6 is positioned in the locking groove 4, thereby positioning the rotary switch 2. Specifically, the operating part 9 of the rotary switch 2 is cuboid in shape. Two second mounting bases 14 are symmetrically arranged on the back of the rotary switch 2, and the second mounting bases 14 are arranged along the long axis of the operating part 9, which is the axis of symmetry of the operating part 9. The second mounting bases 14 are countersunk blind holes, and two positioning components 5 are also adapted to fit. The positioning components 5 are embedded in the second mounting bases 14 and securely installed. Furthermore, the positioning assembly 5 also includes a cylindrical housing 15 and a compression spring 16. The housing 15 forms a mounting cavity 17 with an opening at the front end. One end of the compression spring 16 is securely mounted inside the mounting cavity 17, and the other end of the compression spring 16 is securely connected to the positioning member 6. The positioning member 6 protrudes from the mounting cavity 17. When the positioning member 6 is compressed, it springs back into the mounting cavity 17. The positioning member 6 is a sphere. It should be noted that the positioning member 6 can also be a cylinder, with one end hemispherical and the other end securely connected to the compression spring 16.

[0039] Furthermore, in this embodiment, a mounting groove 18 is formed on the first mounting base 7, and a blocking portion 19 is provided in the mounting groove 18. A boss 20 is formed on the back side of the rotary switch 2, and a flange 21 is provided on the boss 20. The boss 20 is adapted to be installed in the mounting groove 18, and when the flange 21 abuts against the blocking portion 19, it can restrict the rotary switch 2 from continuing to rotate. Specifically, when the rotary switch 2 is rotated to a predetermined position, in order to prevent the rotary switch 2 from continuing to rotate, a mounting groove 18 is provided on the front side of the first mounting base 7, and a blocking portion 19 is formed on the mounting groove 18. The blocking portion 19 is used to restrict the rotary switch 2 from continuing to rotate. More specifically, a boss 20 is formed on the back side of the rotary switch 2, and a flange 21 extends from the edge of the boss 20. When the rotary switch 2 is assembled and connected to the drive shaft 8, when the boss 20 is adapted to be installed in the mounting groove 18, the boss 20 can rotate within the mounting groove 18 as the rotary switch 2 rotates. When the rotary switch 2 is rotated to the predetermined left position, the positioning member 6 pops out and engages with the locking grooves 4 on both sides, completing the left-side positioning of the rotary switch 2. At this time, the edge of the flange 21 abuts against the edge of the blocking part 19, preventing the rotary switch 2 from rotating further to the left. When the rotary switch 2 is rotated to the predetermined upper position, the positioning member 6 pops out and engages with the upper and lower locking grooves 4, completing the initial positioning of the rotary switch 2. At this time, the flange 21 does not abut against the blocking part 19, and the rotary switch 2 can continue to rotate. When the rotary switch 2 is rotated to the predetermined right position, the positioning member 6 pops out and engages with the locking grooves 4 on both sides, completing the right-side positioning of the rotary switch 2. At this time, the edge of the flange 21 abuts against the edge of the blocking part 19, preventing the rotary switch 2 from rotating further to the right.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
