Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent lock, in particular to a lighting device and an intelligent lock. BACKGROUND

[0002] With the rapid development of smart home technology, intelligent locks have become an important part of modern home security due to their convenience and security. Intelligent locks not only integrate fingerprint recognition, password input, Bluetooth unlocking and other high-tech unlocking methods, but also retain the traditional key unlocking function to ensure that users can still enter smoothly in case of emergency or system failure. In the design of intelligent locks, the keyhole, as the key component connecting the key and the lock core, its position and structure have a direct impact on the convenience of unlocking operation. In the current market, many intelligent locks generally adopt a bridge-style design for aesthetics and structural strength, which results in a relatively long key handle and a deep keyhole position inside the door body, which becomes an unavoidable factor for users when using the key to unlock.

[0003] In the prior art, the process of using a key to unlock usually includes aligning the key with the keyhole, inserting and rotating to unlock the lock core. Although this traditional unlocking method is simple and direct, it is subject to various factors in actual application. In particular, when the keyhole position is deep and the user's hand space is limited, the accurate insertion and rotation of the key becomes particularly difficult. In addition, for users with poor eyesight or limited hand flexibility, this operation is even more challenging. Users need to rely on good light conditions to ensure that the key can smoothly enter the keyhole and accurately align the lock core for unlocking.

[0004] However, in actual use scenarios, especially at night or in dimly lit environments, users often face the problem of insufficient light, making it difficult to clearly identify the keyhole, thereby increasing the difficulty of using the key to unlock. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] The embodiments of the present application will be described below in combination with Figures 1 to 7 .

[0039] According to the embodiments of the present application, on the one hand, a lighting device is provided, which is adapted to be arranged in a smart lock and used for illuminating a keyhole 1 and a lock core hole 23, and comprises a lamp plate 2 and a plugging assembly. The lamp plate 2 is adapted to be arranged in the smart lock, and the lamp plate 2 is provided with a switch 3 and a lamp body 4. The plugging assembly is adapted to plug the keyhole 1, and the plugging assembly is switchable between a first position and a second position. In a state of the first position, the plugging assembly abuts against the switch 3, and in a state of the second position, the plugging assembly is separated from the switch 3.

[0040] It can be understood that, in the state of the first position, the plugging assembly not only abuts against the switch 3, but also plugs the keyhole 1 at this time. In the state of the second position, the plugging assembly is not only separated from the switch 3, but also separated from the keyhole 1 at this time, so as to avoid hindering the insertion of a key.

[0041] It should be noted that the switch 3 and the lamp body 4 are electrically connected with the lamp plate 2, and the switch 3, the lamp body 4 and the lamp plate 2 can be regarded as an integrated structure. Usually, a circuit board is used as the base of the lamp plate 2, and the lamp body 4 is generally selected from an LED lamp bead. The circuit board can not only provide power supply for the lamp body, but also be used as a control circuit cooperating with the switch 3 to control the power-on and power-off of the lamp body 4. In the present application, the switch 3 is set as a press switch. When the blocking assembly is separated from the keyhole 1, the press switch 3 is pressed and popped up. At this time, the circuit is always open, and the lamp body 4 is always on. When the blocking assembly blocks the keyhole 1, the press switch 3 is pressed. At this time, the circuit is always closed, and the lamp body 4 is extinguished.

Through the switching of the blocking assembly between the first position and the second position, the intelligent control of the lighting device is realized, that is, when the user needs to open the lock, the blocking assembly is moved to the second position to separate from the switch 3, and the lamp body 4 is turned on. After completing the opening of the lock, the blocking assembly is pushed to the first position and abuts against the switch 3, and the lamp body 4 is extinguished, which is not only energy-saving but also practical.
