Description

Technical Field

[0001] The utility model relates to the technical field of intelligent locks, in particular to a front panel with a hidden keyhole and an intelligent lock. Background Art

[0002] In an intelligent lock, a user generally unlocks the lock through fingerprint unlocking, voice unlocking or other unlocking methods, and rarely uses a key to unlock the lock. However, for safety reasons, the intelligent lock usually uses the key unlocking function as a backup to unlock the lock smoothly when other unlocking methods such as fingerprint unlocking cannot be used normally. Therefore, a lock core is generally inserted on the front panel of the intelligent lock, and the lock core has a keyhole for inserting a key. In a traditional intelligent lock, the keyhole of the lock core is usually directly exposed on the front surface of the front panel. When the environment where the intelligent lock is located has a lot of dust or water vapor, a large amount of external dust or water vapor can easily enter the keyhole of the lock core, which is very likely to damage the internal structure of the lock core, resulting in a situation where the lock core cannot be used normally when the key is needed to unlock the lock. In addition, the lock core exposed on the front surface of the front panel also makes the front panel less beautiful. Content of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a front panel with a hidden keyhole, which can cover and hide the keyhole of the lock core by using a cover plate moved to a first position, thereby reducing the situation that the lock core is damaged due to external substances entering the keyhole. At the same time, the cover plate in the first position does not protrude from the front panel, ensuring the beauty of the front panel.

[0004] The utility model also provides an intelligent lock with the above-mentioned front panel with a hidden keyhole.

[0005] The front panel with a hidden keyhole according to the first aspect embodiment of the present utility model includes a front panel housing and a cover plate. An installation groove is provided on the front surface of the front panel housing, and a lock core installation hole is opened on the bottom wall of the installation groove; the cover plate is movably installed on the front panel housing. The cover plate has a first position and a second position.

[0032] Refer to Figures 1 to 4, The front panel with a hidden keyhole according to the first aspect embodiment of the present utility model includes a front panel housing 100 and a cover plate 200. An installation groove 110 is provided on the front surface of the front panel housing 100. The rear side wall of the installation groove 110 is the bottom wall of the installation groove 110, and a lock core installation hole 120 is opened on the bottom wall of the installation groove 110; the cover plate 200 is movably installed on the front panel housing 100. The cover plate 200 has a first position and a second position. When the cover plate 200 is in the first position, the cover plate 200 closes the installation groove 110 and the front surface of the cover plate 200 is flush with the side wall of the installation groove 110. When the cover plate 200 is in the second position, the cover plate 200 avoids the lock core installation hole 120 and the lower end of the cover plate 200 is located outside the installation groove 110. Among them, the installation groove 110 has an avoidance space 111 for the upper end of the cover plate 200 to be pressed down. When the upper end of the cover plate 200 is pressed down, the lower end of the cover plate 200 moves to the outside of the installation groove 110 to allow the cover plate 200 to slide from the first position to the second position. A reset structure 300 is provided between the cover plate 200 and the front panel housing 100. The reset structure 300 is used to drive the cover plate 200 to return from the second position to the first position. A guiding structure is provided between the cover plate 200 and the front panel housing 100. The guiding structure is used to guide the cover plate 200 to switch between the first position and the second position.

[0033] Refer to Figure 1 and Figure 4 , For the front panel provided by the present utility model, the lock core can be inserted into the lock core installation hole 120 on the bottom wall of the installation groove 110.

At this time, the upper end of the cover plate 200 is pressed down towards the avoidance space 111 in the installation groove 110, and the lower end of the cover plate 200 can move and tilt to the outside of the installation groove 110. At the same time, a frictional force is generated between the human hand and the cover plate 200. Through this frictional force, when the human hand moves downward, under the guidance of the guiding structure, the human hand can drive the cover plate 200 to move downward to the second position at the same time, so that the cover plate 200 avoids the lock core installation hole 120 to expose the keyhole of the lock core. Thus, people can insert the key into the lock core to unlock. After unlocking, if the user releases the cover plate 200, the cover plate 200 can return from the second position to the first position under the action of the reset structure 300. Through the above settings, it is convenient and simple for the user to operate the cover plate 200. Among them, the cover plate 200 in the first position can close the installation groove 110, and then cover and hide the lock core on the bottom wall of the installation groove 110, thereby reducing the situation that external substances enter the keyhole and cause damage to the lock core. At the same time, the front surface of the cover plate 200 in the first position is flush with the side wall of the installation groove 110.
