Description

TECHNICAL FIELD

[0001] The application relates to the technical field of intelligent locks, in particular to a key. BACKGROUND

[0002] With the progress of science and technology and the popularity of smart homes, intelligent locks, as an important part of modern home security, have gradually replaced traditional door locks and become the mainstream of the market. Intelligent locks not only provide more convenient unlocking methods, such as fingerprint recognition, password input, and remote control, but also retain the traditional key unlocking function to ensure that manual unlocking can still be achieved in certain situations. This design takes into account both advanced technology and user habits, so that the key, as a backup unlocking tool, still plays an indispensable role in modern intelligent lock systems.

[0003] In current intelligent lock designs, many products adopt a bridge-style appearance design for aesthetics and structural stability. This design feature results in a relatively long key handle and a deep lock core position inside the door body. When using the key to unlock, the user needs to insert the long key handle deep into the lock hole and accurately align the lock core for rotation. This process not only requires the user to have certain hand flexibility and accuracy, but also relies on good lighting conditions to clearly identify the lock hole position. Especially in the absence of additional lighting assistance, using the key to unlock becomes a challenging task.

[0004] However, in actual use scenarios, especially at night or in dimly lit environments, users often face insufficient light, making it difficult to accurately and quickly insert the key into the lock hole. This not only prolongs the unlocking time, but also may cause damage to the key or lock core due to improper operation, reducing user experience. CONTENT OF THE INVENTION
