[0038] Example 1
[0039] Please see Figure 3This embodiment provides a key device for locking and unlocking a vehicle. The key device includes a housing 1, a physical key module 2, a wireless remote control module 3, and an NFC function module 4, all connected to the housing 1. The physical key module 2 can be matched with the lock cylinder on the vehicle, the wireless remote control module 3 can send lock and unlock control signals to the vehicle, and the NFC function module 4 can sense the NFC device on the vehicle and send lock and unlock information to the NFC device.
[0040] It should be noted that NFC stands for Near Field Communication. Furthermore, the key device in this embodiment can be used to lock and unlock electric bicycles, electric tricycles, electric motorcycles, electric cars, and other electric vehicles.
[0041] With this setup, users can use the physical key module 2 on the key device to lock and unlock the vehicle by inserting the physical key module 2 into the vehicle's lock cylinder. Users can also use the wireless remote control module 3 on the key device to lock and unlock the vehicle by sending a lock / unlock control signal to the vehicle via the wireless remote control module 3. Users can also use the NFC function module 4 on the key device to lock and unlock the vehicle by bringing the NFC function module 4 close to the NFC device on the vehicle and sending lock / unlock information to the NFC device via the NFC function module 4.
[0042] Among them, the physical key module 2 needs to be inserted into the lock cylinder when using it to open and close the lock, which is inconvenient. The wireless remote control module 3 can provide keyless operation, which is very convenient. However, the wireless remote control module 3 relies on the battery 8 and is susceptible to electromagnetic interference and may be attacked by wireless signal relay. The NFC function module 4 can be integrated with a wristband or mobile phone to realize functions. It can be triggered when close to the device, which is convenient to operate. However, it requires close-range operation, so the security is relatively high. However, its use depends on electronic devices such as wristbands or mobile phones. However, electronic devices may run out of power or malfunction, and some users may not be used to using it.
[0043] The key device in this embodiment integrates three unlocking methods: a physical key module 2, a wireless remote control module 3, and an NFC function module 4. Users only need to carry one key device to lock and unlock the vehicle using either the physical key module 2, the wireless remote control module 3, or the NFC function module 4. Therefore, users can choose any unlocking method to lock and unlock the vehicle based on the actual usage scenario. For example, if the wireless remote control module 3 is out of power, either the physical key module 2 or the NFC function module 4 can be used to lock and unlock the vehicle. Similarly, if the mobile phone is out of power or there is NFC interference, either the physical key module 2 or the wireless remote control module 3 can be used to lock and unlock the vehicle.
[0044] In other words, firstly, the key device of this embodiment has a high degree of integration. Users only need to carry one device to have three unlocking methods, greatly improving ease of use. It also eliminates the need to carry multiple unlocking devices simultaneously, improving portability and reducing the number of unlocking devices, thus lowering the risk of loss. Secondly, among the physical key module 2, wireless remote control module 3, and NFC function module 4, if any unlocking module fails (battery 8 depleted or electronic malfunction), the other modules (especially physical key module 2) can serve as effective backups, ensuring that users can always unlock and control the vehicle, improving reliability. Thirdly, the key device of this embodiment can meet the usage habits of different users, such as those who prefer keys, button remote control, or mobile phone / NFC card swiping, etc. It can also meet different usage scenarios, such as using NFC function module 4 for daily commuting or carrying heavy items while shopping, and using physical key module 2 when wireless remote control module 3 is out of power.
[0045] In summary, the key device of this embodiment has high integration performance, is convenient to use, easy to carry, reliable in use, highly adaptable, and provides a good user experience, thus alleviating the technical problems of insufficient convenience and low reliability of electric vehicle keys in the prior art.

The physical key module 2 is rotatably connected to the outer shell 1 and can rotate into the inner cavity 11 and rotate from the inner cavity 11 out of the opening.
[0047] When the physical key module 2 of the key device is needed, the physical key module 2 is rotated from the opening of the inner cavity 11 to the outside of the inner cavity 11, so that the physical key module 2 can be inserted into the lock cylinder of the vehicle; when the physical key module 2 of the key device is not needed, the physical key module 2 is rotated into the inner cavity 11 and stored, reducing the storage volume of the key device and making it easy to carry.
[0048] Preferably, in this embodiment, the wireless remote control module 3 includes a microcontroller and an RF transmitting circuit, the microcontroller and the RF transmitting circuit are electrically connected, and the housing 1 is provided with control buttons, which are electrically connected to the microcontroller.

[0054] Specifically, when the NFC module 4 comes into close contact with the NFC device on the vehicle, the NFC coil can sense the NFC device and generate an induced current. The NFC chip starts up after the current is turned on and sends the unlocking information to the NFC device through the NFC coil.
[0055] Preferably, please refer to Figure 4 In this embodiment, the outer shell 1 is provided with an inner cavity 11, and the NFC chip and NFC coil are both disposed in the inner cavity 11; or the outer surface of the outer shell 1 is marked with an NFC sensing area, and the NFC chip and NFC coil are both disposed in the NFC sensing area.

[0059] Optionally, charging port 9 is a USB-C / Micro USB interface.
[0060] In summary, the key device of this embodiment integrates the advantages of three mainstream methods: physical key module 2, wireless remote control module 3, and NFC function module 4. It provides a vehicle key solution with multiple backups, high convenience, enhanced security, and adaptability to different user habits and usage scenarios, so that users do not need to carry multiple unlocking devices, reducing the burden of carrying and the risk of loss.
[0061] Preferably, the wireless remote control module 3 uses encryption / code skipping technology to prevent copying; the NFC function module 4 uses near-field communication and encryption authentication to prevent relay attacks and avoid temporarily disabling the remote control after NFC authentication, further reducing the risk of wireless attacks.
