[0001] The present invention relates to the technical field of smart door locks, and in particular to a handle locking device for a fully automatic smart door lock. Background Art

[0002] Nowadays, smart door locks are gradually widely used in every household. Today's smart door locks are installed on the left or right side of the door. The lock body is usually locked or opened by rotating the handle to lift or press it down.

[0003] However, according to the actual situation of the hinge connection between the door panel and the door width and the interior layout, the lock body may be installed on the left side of the door panel or on the right side of the door panel. At this time, the smart door lock can only be installed according to the installation position of the lock body. However, because most smart door locks nowadays can only be fixedly installed on the left or right side of the door, when the installation position of the smart door lock is reversed, it will affect the rotation of the handle of the rear lock body, which makes it inconvenient for users to lock or open the door from indoors. It is not suitable for use in today's diverse interior layouts.

[0004] In view of these problems, how to provide a handle locking device for a fully automatic smart door lock that can adapt to different indoor layouts and can be installed on the left or right side of the door panel to facilitate users to open the door from indoors is a technical problem that technicians in this field need to solve.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-2 As shown, a handle locking device of a fully automatic smart door lock includes a transmission assembly, a rear lock body 2 and a bottom plate 3. The bottom plate 3 is installed at the bottom of the rear lock body 2. The transmission assembly passes through the rear lock body 2 and the bottom plate 3 in sequence from the top of the rear lock body 2.

[0028] The transmission assembly includes a handle 11, a steering shaft 12, a square shaft 13 and a reversing member 14. The bottom of the handle 11 is connected to the top of the steering shaft 12, the bottom of the steering shaft 12 is connected to one end of the square shaft 13, and the other end of the square shaft 13 is connected to the external lock body. A reversing member 14 is provided at the connection between the square shaft 13 and the bottom plate 3. The rotation of the handle 11 drives the rotation of the steering shaft 12 connected thereto, and the rotation of the steering shaft 12 drives the rotation of the square shaft 13, thereby realizing operations such as locking or unlocking the external lock body. At the same time, due to the rotation of the square shaft 13, the reversing member 14 installed on the square shaft 13 rotates following the rotation of the square shaft 13, thereby realizing synchronous rotation.

[0029] like Figure 3-6 As shown, a cylinder 141 is provided on the top of the reversing member 14, a hollow column 142 is provided on the bottom thereof, and a protruding column 1411 extending toward the outside of the cylinder 141 is provided on one side of the cylinder 141;

[0030] The base plate 3 is provided with a through hole, which is composed of a semicircular wall A31, two groups of right-angle walls 32, two groups of semicircular walls B33 and a protruding wall 34. The ends of the semicircular wall A31 are respectively connected to one end of the right-angle wall 32 on both sides to form a fan-shaped rotation area 35, and the right-angle wall 32 is used to limit the boss 1411 to rotate only in the rotation area 35. The other ends of the two groups of right-angle walls 32 are respectively connected to one end of the two groups of semicircular walls B33, and the other ends of the two groups of semicircular walls B33 are respectively connected to the ends of the protruding wall 34 to form a groove 36, and the rotation of the boss 1411 is limited by the groove 36.

[0031] like Figure 3 As shown, when the protrusion 1411 on the cylinder 141 at the top of the reversing member 14 points downward in a stationary state, the user can only rotate the handle 11 90° clockwise or 90° counterclockwise, thereby causing the square shaft 13 to rotate 90° clockwise or 90° counterclockwise to lock or unlock the lock body from the outside. This is suitable for ordinary users who need to lock and unlock by rotating the handle 11 from indoors.

[0032] like Figure 4-5 As shown, when the boss 1411 on the cylinder 141 at the top of the reversing member 14 points to the right or left in a stationary state, the user can only unlock the door by rotating the handle 11 90 degrees clockwise, or the user can only unlock the door by rotating the handle 11 90 degrees clockwise, both of which restrict the user from being able to lock the door. This is suitable for users who do not need to lock the door by rotating the handle 11 and can only unlock the door by rotating the handle 11. At the same time, when the installation position of the lock body in the door panel is on the left or right side of the door panel, the installer can adjust the position of the reversing member 14 according to the specific situation until the boss 1411 on the cylinder 141 at the top of the reversing member 14 points to the right or left in a stationary state, thereby adjusting the position of the handle 11 to be suitable for use in the installation position of the lock body in different door panels.

[0033] like Figure 6 As shown, when the boss 1411 on the cylinder 141 at the top of the reversing member 14 points upward in a stationary state and is stuck in the groove 36, the handle 11 cannot be rotated at this time, and thus cannot be unlocked or locked. It is suitable for use in fully automatic door locks that do not require the handle 11 to be locked or unlocked indoors.

[0034] like Figure 7-9 As shown, the handle 11 is provided with a connecting hole 111 at the bottom, and the steering shaft 12 is provided with a connecting post 121 at the top. The steering shaft 12 is clamped and connected to the connecting hole 111 at the bottom of the handle 11 via the connecting post 121. The handle 11 can be clamped and connected to the connecting post 121 of the steering shaft 12 via the connecting block, and can be detached to adjust the specific position of the handle 11 according to different situations.

[0035] A clamping column 122 is provided at the bottom of the steering shaft 12 , and a hollow column 142 is provided at the bottom of the reversing member 14 . The reversing member 14 is clamped and connected to the clamping column 122 at the bottom of the steering shaft 12 via the hollow column 142 .

[0036] like Figure 10 As shown, the central portion of the clamping column 122 is provided with a square shaft hole A1222 connected to the square shaft 13, and the central portion of the reversing member 14 is provided with a square shaft hole B1412 connected to the square shaft 13. The square shaft 13 passes through the square shaft hole B1412 in the central portion of the reversing member 14 and the square shaft hole A1222 in the central portion of the clamping column 122, thereby being clamped into the steering shaft 12. Rotation of the handle 11 drives the rotation of the steering shaft 12 connected thereto, which in turn drives the rotation of the reversing member 14 connected thereto, thereby driving the rotation of the square shaft 13, thereby locking or unlocking the external lock body.

[0037] The connection between the clamping column 122 and the steering shaft 12 is provided with three sets of empty slots 1221 surrounding the clamping column 122 and recessed inwardly along the horizontal direction of the clamping column 122. The PC cables connecting devices such as electronic buttons on the handle 11 can be easily passed through the three sets of empty slots 1221 and connected to the motherboard in the rear lock body 2, eliminating the need for opening holes for cable winding and facilitating organization.

[0038] like Figure 11 As shown, the square shaft hole B1412 is a cube structure consisting of four sets of planes, namely, straight walls 14121, curved walls 14122, and curved walls 14123. The curved walls 14122 are connected between two sets of straight walls 14121, with their apexes facing outward. The outer ends of the two sets of straight walls 14121 are connected to two sets of curved walls 14123, respectively. If the square shaft 13 is damaged and difficult to remove from the reversing member 14, a worker can use pliers to grip the square shaft 13 and swing it left and right or up and down to remove it. Because the curved walls 14122 and curved walls 14123 provide a certain clearance between the square shaft 13 and the square shaft hole B1412, it is relatively easy to remove the square shaft 13, without the need for other equipment.

[0039] The present invention uses methods such as limiting and fixing the reversing member 14 to allow the handle 11 to rotate only clockwise, only counterclockwise, and both clockwise and counterclockwise at the same time, or to directly prohibit its rotation. It can be installed on the left or right side of the door panel according to the installation position of the lock body of the door panel in the specific indoor layout, so that the user can open or lock the door smoothly from the indoor.

[0040] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
