DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses an emergency unlocking structure.

[0034] Reference Figure 1 and Figure 2 An emergency unlocking structure and a smart lock include an operation panel 1, a handle 11 rotatably connected to the operation panel 1, and a positioning rod 12 fixedly connected to the operation panel 1. The positioning rod 12 is located between the operation panel 1 and the handle 11. A positioning groove 13 is provided on the handle 11 at a position corresponding to the positioning rod 12. The end of the positioning rod 12 away from the operation panel 1 is inserted into the positioning groove 13 to limit the rotation of the handle 11. The handle 11 can slide along the length direction of the positioning rod 12. Sliding the handle 11 in a direction away from the operation panel 1 can cause the positioning rod 12 to disengage from the positioning groove 13. Then the handle 11 can be rotated to cause the emergency lock hole on the operation panel 1 to leak out. Emergency unlocking can be achieved without the user having to operate with both hands, which is convenient for the user to use.

[0035] Reference Figure 1 and Figure 2A connecting member 2 is provided between the handle 11 and the operation panel 1, and the connecting member 2 includes a connecting rod 21 and a blocking disk 22. The connecting rod 21 is a cylindrical structure, and the connecting rod 21 is arranged in parallel and spaced relation with the positioning rod 12, and one end of the connecting rod 21 is connected to the operation panel 1. The blocking disk 22 is a disc-shaped structure, and the diameter of the blocking disk 22 is larger than the diameter of the connecting rod 21. The blocking disk 22 is coaxially welded to the end of the connecting rod 21 away from the operation panel 1. A sliding groove 23 is provided on the side of the handle 11 close to the operation panel 1, and the blocking disk 22 is slidably fitted in the sliding groove 23, and the handle 11 can rotate relative to the blocking disk 22. A blocking member 24 is welded on the side wall of the sliding groove 23, and the blocking member 24 is a circular ring structure, and the blocking member 24 is coaxial with the connecting rod 21, and the blocking member 24 is located on the side of the blocking disk 22 close to the operation panel 1. When the handle 11 is slid, the blocking disk 22 can abut against the blocking member 24, thereby preventing the handle 11 from being separated from the connecting member 2.

[0036] Reference Figure 1 and Figure 2 The operation panel 1 is provided with a mounting groove 25, one end of the connecting rod 21 is embedded in the mounting groove 25, and the end of the connecting rod 21 close to the operation panel 1 is provided with a threaded groove. A screw is arranged on the side of the operation panel 1 away from the connecting member 2, passing through the operation panel 1 and threadedly connected in the threaded groove, so as to realize a fixed connection between the connecting rod 21 and the operation panel 1. At the same time, the mounting groove 25 can limit the displacement of the connecting rod 21 in a direction parallel to the operation panel 1, thereby improving the stability of the connecting rod 21 after being connected to the operation panel 1.

[0037] Reference Figure 1 and Figure 2 , a stabilizing component 3 is arranged in the sliding groove 23, and the stabilizing component 3 is used to prevent the handle 11 from moving in a direction away from the operating panel 1 when emergency unlocking is not required. In this embodiment, the stabilizing component 3 includes an elastic member 31, and the elastic member 31 is used to apply a force to the handle 11 to make the handle 11 move in a direction close to the operating panel 1. In this embodiment, the elastic member 31 is a compression spring, which is sleeved on the outside of the connecting rod 21, and the two ends of the compression spring are respectively in contact with the side surfaces of the blocking disk 22 and the blocking member 24 that are close to each other. Under the action of the elastic force, the handle 11 can be prevented from moving in a direction away from the operating panel 1 to a certain extent, thereby improving the stability of the handle 11 when emergency unlocking is not required.

[0038] Reference Figure 1 and Figure 2A stroke limiter 4 is also provided on the side of the handle 11 close to the operating panel 1, and the stroke limiter 4 is used to limit the rotation angle of the handle 11. The stroke limiter 4 is a cylindrical rod-shaped structure, and one end of the stroke limiter 4 is vertically welded to the side of the handle 11 close to the operating panel 1. An arc-shaped groove 41 is provided on the operating panel 1, and the axis of the arc-shaped groove 41 coincides with the rotation axis of the handle 11. The end of the stroke limiter 4 away from the handle 11 is inserted into the arc-shaped groove 41, and can slide along the length direction of the arc-shaped groove 41. When the stroke limiter 4 moves to the end of the arc-shaped groove 41, the side wall of the arc-shaped groove 41 blocks the movement of the stroke limiter 4, thereby limiting the rotation angle of the handle 11.

[0039] The implementation principle of an emergency unlocking structure and a smart lock in an embodiment of the present application is as follows: when emergency unlocking is required, the user can pull the handle 11 with one hand, and when the positioning rod 12 is disengaged from the positioning groove 13, the handle 11 is rotated to make the emergency lock hole leak out for emergency unlocking.

[0040] The present application also discloses a smart lock

[0042] Example 2

[0043] Reference Figure 3 The difference between this embodiment and the first embodiment is that the structure of the stabilizing component 3 is different. In this embodiment, the stabilizing component 3 includes two groups of magnetic members 32, which are respectively bonded to the handle 11 and the operation panel 1 and attract each other. In this embodiment, the magnetic member 32 is a magnet. The handle 11 is blocked from moving away from the operation panel 1 by the mutual attraction of the two groups of magnetic members 32.

[0044] The implementation principle of an emergency unlocking structure and a smart lock in an embodiment of the present application is: through two groups of magnetic parts 32, the handle 11 is blocked from moving in a direction away from the operation panel 1, thereby improving the stability of the handle 11 when no emergency unlocking is required.

[0045] Example 3

[0046] Reference Figure 4The difference between this embodiment and the first embodiment is that the structure of the stabilizing assembly 3 is different. In this embodiment, the stabilizing assembly 3 includes an abutting rod 33 and a reset member 34. The abutting rod 33 is arranged in a direction perpendicular to the axis of the blocking disk 22 and can slide radially along the blocking disk 22. The reset member 34 is installed on the blocking disk 22 and is used to apply a force to the abutting rod 33 to make the abutting rod 33 move in a direction away from the abutting rod 33. A hemispherical surface 36 is provided on the side of the abutting rod 33 away from the axis of the blocking disk 22, and a limiting groove 35 is provided on the side wall of the sliding groove 23. When the handle 11 and the operating panel 1 abut each other, the hemispherical surface 36 can be inserted into the limiting groove 35. Under the action of the reset member 34, the handle 11 can be blocked from moving in a direction away from the operating panel 1 to a certain extent. At the same time, when the force applied by the user to the handle 11 is large enough, the elastic force of the reset member 34 can be overcome to separate the abutting rod 33 from the limiting groove 35, and the limit on the sliding of the handle 11 is cancelled.

[0047] The implementation principle of an emergency unlocking structure and a smart lock in an embodiment of the present application is: one end of the abutment rod 33 is abutted against the limiting groove 35 by the reset member 34, thereby preventing the handle 11 from moving away from the operation panel 1.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
