Description

Technical Field

[0001] This utility model relates to the field of car key technology, and in particular to a smart key with a separate shell and key plate structure. Background Technology

[0002] Car smart keys integrate advanced technologies such as wireless communication and sensor recognition. As long as the key is within the vehicle's sensing range, functions such as keyless entry and one-button start can be achieved. However, to ensure reliability, existing car smart keys still retain a mechanical key. Currently, most car smart keys on the market integrate the circuit board and the mechanical key into the same cavity. To meet the need for removing and using the mechanical key, an opening or gap must be reserved in the cavity for the mechanical key to be pulled out. Even with conventional sealing measures such as rubber sealing rings, frequent pulling operations can easily cause the sealing structure to wear and deform, leading to seal failure. Once the seal is compromised, external contaminants such as moisture and dust can easily enter the cavity. Moisture condensation can easily cause short circuits on the circuit board, while long-term dust accumulation can affect the signal transmission of electronic components on the circuit board, thereby shortening the lifespan of the circuit board and increasing the probability of smart key malfunction.
