Description

Technical Field

[0001] The utility model relates to the technical field of smart locks, and in particular to a rotating hidden front panel component and a smart lock. Background Art

[0002] As a composite lock, the smart lock is improved on the basis of the traditional mechanical lock. The smart lock is composed of a front panel assembly and a rear panel assembly, and its functions are realized through a mechanical key module and a smart key module. Among them, the mechanical key module is the mechanical lock part, which is usually used as a backup lock when the smart key module is not in a working state. At present, in order to facilitate users to use the mechanical key module when the smart key module is not in a working state, the lock core hole (keyhole) of the smart lock on the market is generally set on the front surface of the panel of the front panel assembly for key insertion. However, the smart lock adopts the above design, which easily causes its keyhole to be damaged by non-human and human factors, and its anti-theft performance is poor.

[0003] How to cleverly hide the lock core hole of the smart lock to improve the anti-theft performance has become a technical problem that urgently needs to be solved in this field. Summary of the invention

[0004] The purpose of the utility model is to solve the deficiencies of the prior art and provide a rotating hidden front panel assembly and a smart lock based thereon.

[0005] The technical solution adopted by the utility model is: a rotating hidden front panel assembly, including a front panel, a handle and a handle connecting assembly arranged between the front panel and the handle; wherein,

[0006] The handle connection assembly includes a rotating connection piece and a base; one end of the rotating connection piece is fixedly connected to the handle, and the other end is rotationally connected to the front panel; the base is fixedly connected to an end of the rotating connection piece close to the front panel; a rotation control key for controlling the rotation of the rotating connection piece relative to the front panel is provided on the rotating connection piece; the handle drives the handle connection assembly to rotate relative to the front panel to open or hide the lock core hole.

[0007] Preferably, one end of the rotary control key is elastically connected to the connection between the handle and the rotary connector, and the other end is snap-connected to the connection between the base and the front panel.

[0008] Preferably, a control key spring is provided at the connection between the rotation control key and the handle; the base is provided with a through hole for the rotation control key to pass through at a position corresponding to the rotation control key, and the front panel is provided with a concave hole for the rotation control key to abut against at a position corresponding to the rotation control key.

[0009] Preferably, the rotary control key is provided with a pulling portion for conveniently pulling the rotary control key toward the handle.

[0010] Preferably, the rotating connector has a rotating shaft extending outwardly at the end portion facing the front panel.

[0011] Preferably, the outer end surface of the rotating shaft is provided with a limit clamping plate for limiting the rotation angle of the rotating control key, and the front panel is provided with a rotating installation recess for movably clamping the limit clamping plate.

[0012] Preferably, a fan-shaped limiting portion is extended outwardly from the side surface of the limiting clamping plate, and a limiting protrusion for engaging with the fan-shaped limiting portion is provided on the rotation installation recess.

[0013] Preferably, a marble positioning mechanism is provided between the base and the front panel.

[0014] Preferably, the marble positioning mechanism includes a plurality of positioning marbles arranged on the side of the lock core hole by springs, and the inner side surface of the base is provided with positioning pits matching the positioning marbles.

[0015] A smart lock comprises the above-mentioned rotating hidden front panel assembly.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. The smart lock of the utility model cleverly hides the lock core hole at the corresponding position where the front panel contacts the base by rotating the hidden front panel assembly; and also uses the rotation control key hidden on the rotating connector as a rotation switch, so that the operator must pull the rotation control key while rotating the handle and driving the handle connection assembly to rotate relative to the front panel to open the lock core hole. If the operator does not know that the handle can be rotated, or does not know that the rotation control key must be pulled at the same time to unscrew the base, it is impossible to find the lock core hole for artificial damage. This design can effectively improve the anti-theft performance of the smart lock.

[0018] 2. The intelligent lock of the utility model has a rotating hidden front panel assembly that cooperates with a limit card plate and a rotation installation recess on the front panel, and a marble positioning mechanism is provided between the base and the front panel, which limits the rotation angle range of the handle and prevents the handle from rotating excessively.

DETAILED DESCRIPTION

[0029] In order to deepen the understanding of the utility model, the utility model will be further described in detail below with reference to implementation cases and drawings. The utility model can be implemented in the following ways:

[0030] Reference Figure 1-8 The rotating hidden front panel assembly includes a front panel 1, a handle 2, and a handle connecting assembly 3 disposed between the front panel 1 and the handle 2. The handle 2 drives the handle connecting assembly 3 to rotate relative to the front panel 1 to open or hide the lock core hole 11.

[0031] Specifically, the handle connection assembly 3 includes a rotating connection member 31 and a base 32; one end of the rotating connection member 31 is fixedly connected to the handle 2, and the other end is rotationally connected to the front panel 1, so that the rotating connection member 31 can rotate synchronously with the handle 2; the base 32 is fixedly connected to the end of the rotating connection member 31 close to the front panel 1, so that the base 32 can rotate synchronously with the rotating connection member 31; the rotating connection member 31 is provided with a rotation control key 33 for controlling the rotation of the rotating connection member 31 relative to the front panel 1; since the lock core hole 11 of the utility model is arranged at the corresponding position where the front panel 1 and the base 32 are connected, by pulling up the rotation control key 33, the handle 2 can drive the rotating connection member 31 and the base 32 to rotate relative to the front panel 1, thereby opening or hiding the lock core hole 11.

[0032] The rotation control key 33 is movably embedded in the rotation connection member 31. One end of the rotation control key 33 is elastically connected to the connection between the handle 2 and the rotation connection member 31, and the other end is clamped with the connection between the base 32 and the front panel 1. Specifically, a control key spring 34 is provided at the connection between the rotation control key 33 and the handle 2, the base 32 is provided with a through hole 321 for the rotation control key 33 to pass through at a position corresponding to the rotation control key 33, and the front panel 1 is provided with a concave hole 12 for the rotation control key 33 to abut against at a position corresponding to the rotation control key 33. The rotation control key 33 is provided with a lifting portion 331 for facilitating the lifting of the rotation control key 33 toward the handle 2. In static state, one end of the rotation control key 33 passes through the through hole 321 on the base 32 and abuts against the concave hole 12 of the front panel 1, so that the base 32 cannot rotate relative to the front panel 1. When the lifting portion 331 of the rotation control key 33 is pulled upward (i.e., toward the direction where the handle 2 is located), the control key spring 34 is compressed, and the rotation control key 33 is disengaged from the recessed hole 12 of the front panel 1, so that the base 32 can rotate relative to the front panel 1. When the base 32 can rotate, there is no need to pull the rotation control key 33; when the base 32 rotates back to the original position, that is, when the through hole 321 on the base 32 is connected with the recessed hole 12 of the front panel 1, one end of the rotation control key 33 passes through the through hole 321 on the base 32 again and abuts against the recessed hole 12 of the front panel 1, thereby locking the base 32. This design cleverly hides the lock core hole 11 at the corresponding position where the front panel 1 contacts the base 32; and also uses the rotation control key 33 hidden on the rotation connection member 31 as a rotation switch, so that the operator must pull the rotation control key 33 while turning the handle 2 and driving the handle connection assembly 3 to rotate relative to the front panel 1 to open the lock core hole 11. This design can effectively improve the anti-theft performance of the smart lock.

[0033] The rotating connecting member 31 has a rotating shaft 311 extending outwardly at the end facing the front panel 1. The outer end surface of the rotating shaft 311 is provided with a limit card plate 312 for limiting the rotation angle of the rotating control key 33. The limit card plate 312 of this embodiment is circular, and a fan-shaped limit portion 313 extends outwardly from the side of the limit card plate 312. The front panel 1 is provided with a rotating installation recess 13 for the limit card plate 312 to be movably engaged, and the rotating installation recess 13 is provided with a limit convex portion 14 for engaging the fan-shaped limit portion 313. The rotating installation recess 13 is composed of two semicircles with different diameters, and the connection between the two semicircles forms the limit convex portion 14.

[0034] A marble positioning mechanism is provided between the base 32 and the front panel 1. The marble positioning mechanism includes a plurality of positioning marbles 15 arranged on the side of the lock core hole 11 through a spring 16, and a positioning pit 322 matching the positioning marbles 15 is provided on the inner side of the base 32. When the base 32 rotates relative to the front panel 1, the positioning marbles 15 are pressed inward by the pressure of the base 32 to press the spring 16; when the base 32 is rotated and reset, the positioning pit 322 on the base 32 just rotates to the corresponding position of the positioning marble 15, so that the positioning marble 15 is embedded in the positioning pit 322 under the elastic force of the spring 16 to achieve positioning, thereby limiting the rotation angle range of the handle 2 and preventing the handle 2 from rotating excessively.

[0035] A smart lock includes the above-mentioned rotating hidden front panel assembly. The smart lock also includes components such as a smart key module, a mechanical key module, and a rear panel. For the smart lock of the utility model, the operator must pull the rotating control key 33 while rotating the handle 2 and driving the handle connection assembly 3 to rotate relative to the front panel 1 to open the lock core hole 11, thereby improving the anti-theft performance.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
