Currently, smart door locks offer a variety of unlocking methods, such as facial recognition or fingerprint recognition (based on biometrics), remote control via mobile app, or Bluetooth remote key. Among these, the Bluetooth remote key, being portable and compact, meets the needs of some customers. However, existing Bluetooth remote keys are relatively small, and users may easily lose them due to carelessness, changing clothes, or other reasons. Utility Model Content

[0003] In view of this, the present invention provides a Bluetooth remote control key and a Bluetooth remote control key locating system to solve the problem that Bluetooth remote control keys are not easy to find.

[0004] In a first aspect, this utility model provides a Bluetooth remote control key, comprising:

[0005] A Bluetooth chip that supports the Find My function can be paired with a remote mobile device with an application deployed on it to receive the first search signal from the remote mobile device.

[0006] An indicator device, connected to a Bluetooth chip, is used to issue indicator information based on a first search signal.

[0007] The Bluetooth remote control key provided by this utility model, by deploying a Bluetooth chip that supports the Find My function, receives the search signal from the bound remote mobile device, and the indicator device issues an indicator signal based on the search signal. This enables the Bluetooth remote control key to integrate anti-loss and unlocking functions in a simple structure. When the Bluetooth remote control key cannot be found remotely, the user can find it directly according to the indicator information, avoiding the situation where the Bluetooth remote control key is not easy to find due to its small size and wastes time, thus providing convenience for the user.

[0008] In one alternative implementation, the Bluetooth remote key further includes: a button connected to a Bluetooth chip for generating an opening signal and sending the opening signal to a smart lock bound to the Bluetooth remote key via the Bluetooth chip.

[0009] This invention deploys buttons on Bluetooth remote control keys, enabling direct remote door opening based on button operation. This makes the keys difficult to copy and avoids the insecurity of door lock unlocking methods such as biometric identification.

[0010] In one alternative implementation, the indicating device includes: a buzzer connected to a Bluetooth chip for emitting an indicating sound based on a first search signal and a door opening signal; and an indicator light connected to the Bluetooth chip for emitting an indicator light based on the first search signal and the door opening signal.

[0011] This invention, by deploying a buzzer and indicator light, can directly emit sound and light indications when the Bluetooth remote control key cannot be found, intuitively showing the user the location of the Bluetooth remote control key and making it easier for the user to find it.

[0012] In one optional implementation, the Bluetooth remote control key further includes: a radio frequency identification (RFID) reader / writer connected to a Bluetooth chip, used to periodically read the RFID information of an RFID tag placed on a preset item; if the tag cannot be read, a second search signal is generated and sent to an indicator device via the Bluetooth chip, and the indicator device issues an indication message based on the second search signal.

[0013] This invention, by deploying an RFID reader / writer, can determine whether a Bluetooth remote control key has been dropped through communication with the RFID tag, and promptly send a notification to the user when it is dropped to prevent loss.

[0014] In one alternative implementation, the Bluetooth remote key further includes: a battery for providing power to the Bluetooth remote key; and a power chip for voltage conversion of the power supply.

[0015] This invention, by deploying a battery and power chip in the Bluetooth remote control key, can convert the power provided by the battery into the voltage required by the Bluetooth chip, ensuring the normal use of the Bluetooth remote control key and providing users with convenient unlocking.

[0016] In one alternative implementation, the Bluetooth remote key further includes a storage device for storing configuration information of the Bluetooth remote key.

[0017] In one optional embodiment, the storage device includes: a program storage device for storing the software program of the Bluetooth remote control key; and a data storage device for storing the operating data of the Bluetooth remote control key.

[0018] This invention, by deploying a storage device, can provide users with different functions based on the stored configuration information, thereby meeting users' needs.

[0019] Secondly, this utility model also provides a Bluetooth remote control key locator system, comprising:

[0020] The Bluetooth remote control key of the first aspect above or any corresponding embodiment is used to unlock the smart door lock;

[0021] A remote mobile terminal with an application deployed is pre-bound to a Bluetooth remote key to generate a first search signal for the Bluetooth remote key;

[0022] An RFID tag is placed on a pre-defined item and pre-connected to a Bluetooth remote key to generate a second search signal for the Bluetooth remote key based on the communication status.

[0023] This utility model provides a Bluetooth remote key locator system that integrates anti-loss and unlocking functions into a simple structure. When the Bluetooth remote key cannot be found, it can be remotely located by the user sending instructions via a remote mobile terminal. This avoids the problem of Bluetooth remote keys being difficult to find due to their small size, thus saving time and providing convenience for users. Simultaneously, by attaching an RFID tag to a preset item, the system can determine whether the Bluetooth remote key has been dropped based on its communication status with the item, preventing accidental loss or theft.

[0024] In some alternative implementations, the remote mobile terminal is an Apple system mobile terminal, and the application deployed on the Apple system mobile terminal is the Find My application and / or the door lock application.

[0025] This invention binds a Bluetooth remote key to an Apple mobile terminal's Find My application and / or a door lock application. The Find My application enables the Bluetooth remote key to send a search notification, regardless of distance, and can also plan a search route for the user, helping them quickly locate the Bluetooth remote key. The door lock application enables the Bluetooth remote key to function as a door lock, integrating anti-loss and door unlocking functions into one device.

[0026] In one alternative implementation, the remote mobile terminal is an Android system mobile terminal, and the application deployed on the Android system mobile terminal is a door lock application.

[0027] This invention binds a door lock application on an Android mobile terminal to a Bluetooth remote key, providing Android users with anti-loss and door-opening functions for the Bluetooth remote key, thus expanding the applicable scenarios for the Bluetooth remote key.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] This utility model embodiment is applicable to scenarios where a Bluetooth remote control key is used for unlocking doors and also serves as an anti-loss device. This utility model embodiment provides a Bluetooth remote control key that integrates unlocking and anti-loss functions by deploying a Bluetooth chip with Find My functionality on the key. The following describes... Figures 1 to 6 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, in one aspect, a Bluetooth remote control key is provided, comprising:

[0039] The Bluetooth chip 100, which supports the Find My function, is paired with a remote mobile device with an application deployed on it to receive the first search signal from the remote mobile device.

[0040] The indicator device 200 is connected to the Bluetooth chip 100 and is used to issue indicator information based on the first search signal.

[0041] Specifically, in the embodiments of this utility model, such as Figure 1 As shown, the Bluetooth chip 100 of the Bluetooth remote key supports the Find My function. Find My is an application developed by Apple that helps locate lost items. The Find My function provides third-party interfaces for better service without compromising user privacy; neither Apple nor third parties know the phone's exact location except for the user. Apple's Find My technology uses Bluetooth signals from Apple devices to create a network of devices to locate lost items. It can locate not only Apple devices such as iPhones, Macs, and Apple Watches, but also third-party devices. This invention, by deploying a Bluetooth chip 100 supporting the Find My function in the Bluetooth remote key, allows the Bluetooth remote key to be bound to an application on a remote mobile device. When the user cannot find the Bluetooth remote key, they can send a search signal through the mobile application on the remote mobile device. Upon receiving the search signal, the Bluetooth chip 100 of the Bluetooth remote key can directly control the indicator device 200 to issue an indication message. The remote mobile device can be an Apple system mobile terminal or an Android system mobile terminal. If it is an Apple system mobile terminal, the Find My APP (Application) and the door lock APP corresponding to the smart door lock can be installed. If it is an Android system mobile terminal, only the door lock APP can be installed.

[0042] In some alternative implementations, such as Figure 1 As shown, the Bluetooth remote key also includes a button 300, which is connected to a Bluetooth chip 100 to generate an opening signal. This signal is then sent via the Bluetooth chip 100 to the smart lock bound to the Bluetooth remote key. Figure 2As shown, button 300 is positioned in the center of the Bluetooth remote key. When a user approaches the smart lock, they can directly press button 300 to open it. This operation is convenient and avoids the copyability and insecurity of biometric unlocking methods such as fingerprint and facial recognition. Furthermore, users can configure the Bluetooth remote key via button 300. For example, a single press unlocks the door, a 5-second long press enters pairing mode, a 10-second long press powers it off, and there are also options to restore factory settings. Different indicator lights flash different colors to help users understand the current state. This is just an example and not a limitation. Additionally, when the Bluetooth remote key enters pairing mode via button 300, it simultaneously sends out different service lists, supporting various protocols. Both the Find My APP and the door lock APP can search for and bind this Bluetooth remote key.

[0043] In some alternative implementations, such as Figure 1 As shown, the indicator device 200 of the Bluetooth remote control key includes: a buzzer 201, connected to the Bluetooth chip 100, used to emit an indicator sound based on a search signal and a door opening signal; and an indicator light 202, connected to the Bluetooth chip 100, used to emit an indicator light based on the search signal and the door opening signal. When the user cannot find the Bluetooth remote control key, they can send a search signal through an application on a remote mobile device. After receiving the search signal, the Bluetooth remote control key directly controls the buzzer to emit a clear and continuous sound, and can also control the indicator light to light up or flash, making it convenient for the user to quickly find the key's location.

[0044] In some alternative implementations, the Bluetooth remote key integrates anti-loss and door-opening functions; the implementation of these functions depends on the type of remote mobile device and the deployed application. For example... Figure 3 As shown, if the user is using an Apple system remote mobile device, such as an iPhone, and only the Find My app is installed on the iPhone, and the Bluetooth remote key is only paired with the Find My app on the iPhone, then the Bluetooth remote key can be used as an anti-loss device. This Bluetooth remote key is very small, making it easy for users to hang it on other items. When forgetting where the item is placed, users can open the Find My app on their iPhone to search for the anti-loss device. The Find My app will display the location of the anti-loss device on the map. Clicking to play a sound will cause the anti-loss device's buzzer to emit a clear and continuous sound, and the light may also illuminate or flash to help users quickly find the key's location. Alternatively, clicking on the route in the Find My app will display route planning to guide the user to find the Bluetooth remote key. There are no distance limitations between the phone and the Bluetooth remote key.

[0045] In some alternative implementations, such as Figure 3As shown, if a user's Apple phone only has a door lock app installed, and the Bluetooth remote key is only paired with the door lock app, then the Bluetooth remote key can be used both as a door lock to unlock the door and as a proximity anti-loss device. The door lock app supports a key search function, which is mainly based on Bluetooth Low Energy (BLE) iBeacon for proximity positioning. iBeacon is a micro-positioning system based on Bluetooth Low Energy (BLE) technology. The Bluetooth remote key uses BLE to send its unique ID (Identity Document) to the surrounding environment. The phone receives this ID signal and uses the received signal strength (RSSI) of the iBeacon signal to determine the distance between the user and the Bluetooth remote key. When the user clicks the "Find Key" button on the door lock app, the Bluetooth remote key's buzzer emits a clear and continuous sound, and the light may also illuminate or flash to help the user quickly locate the key. If the distance between the mobile phone and the Bluetooth remote key is too far and the Bluetooth connection is lost, the door lock APP will display that the key connection has been lost. At this time, the key search function will be invalid. Therefore, the anti-loss function is limited by the distance between the mobile phone and the Bluetooth remote key.

[0046] In some alternative implementations, such as Figure 3 As shown, if a user has both the Find My app and the door lock app installed on their Apple phone, and the Bluetooth remote key is paired with both apps, then the Bluetooth remote key can be used both as a key to unlock the door and as an anti-loss device. The anti-loss function allows the user to locate the Bluetooth remote key via BLE short-range search through the door lock app, or through the Apple Find My app; further details will not be provided here.

[0047] In some alternative implementations, such as Figure 3As shown, if the user is using an Android-based remote mobile device, such as an Android phone, and the Android phone can only install a door lock app, then the Bluetooth remote key is paired with the door lock app on the Android phone. In this case, the Bluetooth remote key can be used both as a key and as an anti-loss device. The door lock app supports locating the Bluetooth remote key via BLE, primarily based on Bluetooth Low Energy (BLE) iBeacon for short-range positioning. The Bluetooth remote key uses BLE to send its unique ID to the surrounding area. The phone receives this ID signal and uses the RSSI signal strength of the received iBeacon signal to determine the distance between the user and the iBeacon device. Clicking the "Find Key" button on the door lock app will cause the Bluetooth remote key's buzzer to emit a clear and continuous sound, and the light may also illuminate or flash to help the user quickly locate the key. If the distance between the phone and the Bluetooth remote key is too far and the Bluetooth connection is lost, the door lock app will display "Key connection lost," at which point the "Find Key" function will fail, and the anti-loss function will be limited by the distance between the phone and the Bluetooth remote key.

[0048] In some alternative implementations, if the Bluetooth remote key is used as an anti-loss device, it is typically placed in the person's pocket, hung around their neck or wrist, or inside the anti-loss object, such as a wallet or bag, or placed together with the anti-loss object. When the Bluetooth remote key is separated from the person or object being prevented from being lost, it cannot be detected or the user will be notified, for example, if the anti-loss device accidentally falls out of the pocket, the hook breaks, it is taken away, or the user changes clothes. If it is only used as a key, it may also be placed in a pocket or hung on a bag, so there is also the possibility of accidental loss, hook damage, removal, or changing clothes; in these cases, the user still cannot detect or be notified. Therefore, if... Figure 1 As shown, the Bluetooth remote control key of this utility model also includes a radio frequency identification (RFID) reader / writer 400, connected to the Bluetooth chip 100. This device periodically reads the RFID information of RFID tags placed on preset items. If no information is found, a search signal is generated and sent to the indicator device 200 via the Bluetooth chip 100. The indicator device 200 then issues an indication based on the search signal. For example... Figure 3 As shown, users simply need to attach an RFID tag to the person or object they want to prevent from being lost. The Bluetooth remote key records the RFID information and periodically reads the RFID tag. Reading the RFID information means that the Bluetooth remote key and the person or object being prevented from being lost are together. If the RFID information cannot be read continuously, it is determined that the two have been separated. The Bluetooth remote key will flash its light, sound a buzzer, or send a message through the door lock APP to remind the user to check the specific location of the Bluetooth remote key and the person or object being prevented from being lost in time to determine whether they are still in the same place and then take necessary measures.

[0049] In some alternative implementations, such as Figure 4 and Figure 5 As shown, the Bluetooth remote control key of this embodiment also includes: a battery 500 for providing power to the Bluetooth remote control key; and a power chip 600 for voltage conversion. The power chip 600 converts the voltage of the battery 500 into the voltage required by the Bluetooth chip 100, which may be more than one voltage. For example, if the battery is 3.7V, but the Bluetooth chip requires 3.3V and 1.2V, then the power chip 600 is needed for power conversion and management. The Bluetooth remote control key also includes: a storage device 700 for storing the configuration information of the Bluetooth remote control key. The storage device 700 includes: a program storage device 701 for storing the software program of the Bluetooth remote control key, such as Flash, which is retained even when power is lost; and a data storage device 702 for storing the operating data of the Bluetooth remote control key, such as RAM, which is lost when power is lost. Figure 6 As shown, the various devices are assembled together by the upper and lower covers to form a compact Bluetooth remote control key.
