[0031] Refer to together Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , embodiments of the present utility model disclose an anti-lost watch, which can be a quartz watch or a mechanical watch that users wear on their wrists daily. The anti-lost watch is used for wireless communication connection with a mobile terminal. The mobile terminal may include devices such as mobile phones, tablet computers, laptop computers, and smart watches.

[0032] In some embodiments, the anti-lost watch may include a watch body 1, a flight mechanism 2, a main control device 3, a Bluetooth chip 4, a positioning device 5, a power module 6, and a storage module 7. The flight mechanism 2, the main control device 3, the Bluetooth chip 4, the positioning device 5, the power module 6, and the storage module 7 are all assembled on the watch body 1: and the Bluetooth chip 4, the positioning device 5, and the flight mechanism 2, the power module 6, and the storage module 7 are all electrically connected to the main control module. The flight mechanism 2 is used to drive the watch body 1 to move in position. The main control device 3 is used to control the flight mechanism 2 to move the watch body 1 to a set position. The Bluetooth chip 4 is used to pair with the mobile terminal and perform wireless communication connection; the positioning device 5 is used to confirm the real-time position and the set position of the watch body 1; the main control device 3 confirms the movement route of the watch body 1 from the real-time position to the set position according to the real-time position and the set position of the watch body 1. The power module 6 provides power required for each operation of the anti-lost watch. The storage unit is used to store data.

[0033] Refer to together Figure 7 , specifically, when the anti-lost watch is close to the paired mobile terminal, the distance is generally within a space of dozens of meters, and the anti-lost watch will utilize the low-power consumption feature of the Bluetooth chip 4 to continuously broadcast and search externally at a set frequency for a long time, automatically identify the paired mobile terminal and locate the real-time position information of the watch body 1. When the paired mobile terminal is recognized, it will automatically upload the real-time position information of the watch body 1 to the cloud server through the paired mobile terminal for storage, for the user to obtain.

[0034] When the user actively activates the search function on the mobile device, the Bluetooth chip 4 inside the anti-lost watch will receive the connection signal sent by the mobile device. After the mobile device successfully connects to the anti-lost watch, the Bluetooth chip 4 will send a connection success message to the main device to guide and activate the main control device 3 inside the anti-lost watch. According to the connection success message, the main control device 3 sends working information to the positioning device 5 to wake up the positioning device 5 and the flight mechanism 2. After receiving the working information, the positioning device 5 can use ultra-wideband technology to achieve ranging, which can reach centimeter-level accuracy, and is used to calculate the three-dimensional coordinates of the anti-lost watch in the local coordinate system. Then, based on the extended Kalman filter, a variety of sensor data is fused to improve the positioning accuracy of the anti-lost watch, so as to determine the real-time position of the watch body 1 and confirm the set position, and generate and send the real-time position information and the set position information to the main control device 3 in real time. After receiving the real-time position information and the set position information, the main control device 3 calculates the flight route of the watch body 1 from the real-time position to the set position information, and controls the flight mechanism 2 to fly according to this flight route, moving the watch body 1 from the real-time position to the set position, facilitating the user to retrieve the anti-lost watch. The storage unit can store the relevant data of each real-time position information, set position information, and flight route for the user to view or use later.

[0035] Refer to together Figure 8 and Figure 9 , specifically, when the distance between the anti-lost watch and the paired mobile device is relatively far, generally exceeding hundreds of meters or hundreds of kilometers. The Bluetooth chip 4 of the anti-lost watch will always be in a working state automatically. When the Bluetooth chip 4 senses the surrounding intelligent devices (which can also be the intelligent devices of strangers, such as smartphones, computers, tablets, independent communication watches, smart TVs, etc.), the main control device 3 will control the Bluetooth chip 4 to send a help request message to the intelligent device to request the assistance and consent of the user of the intelligent device. When the user of the intelligent device agrees to assist, the Bluetooth chip 4 pairs with the intelligent device of the assistant (i.e., the user of the intelligent device). After the pairing is successful, it sends a successful assistance pairing message to the main control device 3. According to the successful assistance pairing message, the main control device 3 generates encrypted real-time position information and a key, and then automatically uploads the real-time position information and the key to the controlled public service cloud through the intelligent device of the assistant. This public service cloud is maintained and associated by the authoritative department to ensure that the privacy data of the anti-lost watch user and the assistant is not illegally obtained and used. When the user of the anti-lost watch activates the search function of the initially paired mobile device, the mobile device will obtain these encrypted real-time position information and keys from the public service cloud and parse the positioning data of the relevant real-time position. Thus, the user can obtain the real-time position of the anti-lost watch that is relatively far away from him, facilitating the retrieval of the anti-lost watch.

[0036] In some embodiments, the watch body 1 may include a watch case 10, a surface glass 11, a back glass 12, a crown 13, a shaft hole, a receiving groove 14, a guide sleeve 15, a through hole 16, a first waterproof gasket 17, and a second waterproof gasket 18. The watch case 10 serves as the outer shell of the watch body 1. On the one hand, its interior is used to assemble other parts of the anti-lost watch, and on the other hand, it can protect the parts assembled inside it. Inside the watch case 10, a dial and a movement can be assembled. The dial can be used to display time and the states of day and night. The time therein can include the moments of each day and the date, and the date includes year, month, day, and week. On the dial, there are assembled watch hands for rotating timing, time points for indicating time, and Arabic numerals or Roman numerals that cooperate with the time points. The movement is used to control the movement of the watch hands and maintain the walking accuracy of the watch hands, thereby ensuring the accuracy of the timing of the anti-lost watch. The surface glass 11 is assembled on the watch case 10 and is located on the outer side of the dial to protect the dial and the watch hands, and on the other hand, it also plays a decorative role. The back glass 12 is assembled on the watch case 10 and is located on the side in contact with the user's wrist to enhance the comfort of the user's wearing. The crown 13 is provided on the side of the watch case 10 and cooperates with the movement inside the watch case 10 for adjusting time and calibration. The shaft hole is provided on the side of the watch case 10 and penetrates through the watch case 10. The shaft hole is used to set the flight mechanism 2 so that the flight mechanism 2 is assembled on the watch case 10. The receiving groove 14 is formed by the outer surface of the watch case 10 recessing inward and is located on the periphery of the shaft hole for cooperating with the components of the flight mechanism 2. The guide sleeve 15 is provided in the above-mentioned shaft hole, and the guide sleeve 15 is tightly connected to the side wall of the shaft hole for guiding the aircraft mechanism to be assembled on the housing. The through hole 16 is provided in the middle of the guide sleeve 15 and penetrates through the guide sleeve 15. The setting direction of the through hole 16 is the same as the setting direction of the shaft hole, that is, the axis of the through hole 16 is parallel to or on the same straight line as the axis of the shaft hole for the flight mechanism 2 to be inserted into the guide sleeve 15. The first waterproof gasket 17 is provided between the gaps of the watch case 10 for waterproofing and dustproofing, maintaining the dryness and cleanliness inside the watch case 10, and thereby ensuring that its internal parts have a good working environment to ensure the timing accuracy of the anti-lost watch. The second waterproof gasket 18 is provided inside the watch case 10 and is provided between the gaps of the flight mechanism 2 and the guide sleeve 15 to prevent water or dust from entering the inside of the watch case 10 through the gaps between the flight mechanism 2 and the guide sleeve 15.

[0037] In some embodiments, the watch case 10 can be made of materials such as stainless steel, gold, platinum, and ceramic. The cross-sectional shape of the watch case 10 can be circular or rectangular. When manufacturing a anti-lost watch for women, the size of its watch case 10 is usually smaller than that of the same style anti-lost watch for men. The watch case 10 can include a side case 101 and a back case 102 connected to the side case 101. The watch glass is assembled inside the side case 101. The above-mentioned shaft hole is provided on the side case 101 and penetrates through the side case 101. The guide sleeve 15 is arranged in the shaft hole, and the inner end surface of the guide sleeve 15 is flush with the inner side surface of the side case 101. The outer end surface of the guide sleeve 15 is spaced from the outer side surface of the side case 101 by a certain distance to prevent the outer end of the guide sleeve 15 from affecting the depth dimension of the receiving groove 14. The receiving groove 14 is formed by inward depression of the outer surface of the side case 101 and is located on the circumferential side of the shaft hole, that is, the shaft hole is provided in the middle of the receiving groove 14. The first waterproof gasket 17 is arranged at the gap where the side case 101 and the back case 102 are connected.

[0038] In some embodiments, the through hole 16 can include an inner hole and an outer hole connected in sequence from inside to outside. The diameter of the outer hole is larger than that of the inner hole so that a step is formed at the connection position of the inner hole. The diameter of the outer hole is larger than the diameter of the rotating shaft 22, which facilitates guiding the rotating shaft 22 to be inserted into the inner hole through the outer hole.

[0039] In some embodiments, the flight mechanism 2 can include a rotating motor 21, a rotating shaft 22, rotating blades 23, and a fixing seat 24. The rotating motor 21 is arranged inside the watch case 10. The rotating shaft 22 is inserted through the shaft hole so that the first end of the rotating shaft 22 is arranged inside the watch case 10, and the second end of the rotating shaft 22 is arranged outside the watch case 10. The first end of the rotating shaft 22 is connected to the output shaft of the rotating motor 21, and the rotating blades 23 are connected to the second end of the rotating shaft 22. The main control device 3 controls the opening and closing of the rotating motor 21 through electrical connection with the rotating motor 21. The rotating motor 21 is fixedly arranged inside the watch case 10 through the fixing seat 24. When the flight mechanism 2 works, the rotating motor 21 drives the rotating shaft 22 to rotate, and then drives the rotating blades 23 to rotate, thereby driving the watch body 1 to fly and thus move its position. The flight principle of the flight mechanism 2 driving the watch body 1 can refer to the flight principle of an aircraft with rotating blades 23.

[0040] Specifically, the rotating electric machine 21 is a telescopic rotating electric machine 21 for converting the rotating shaft 22 between a first state and a second state. The first state is the state where the second end of the rotating shaft 22 is close to the rotating electric machine 21, and the second state is the state where the second end of the rotating shaft 22 is far from the rotating electric machine 21. On the one hand, the rotating electric machine 21 can drive the rotating shaft 22 to rotate, and on the other hand, it can drive the rotating shaft 22 to perform a telescopic motion relative to the rotating electric machine 21. When the flight mechanism 2 is not working, the rotating shaft 22 is in the first state; when the flight mechanism 2 is working, the rotating shaft 22 is in the second state.

[0041] The rotating shaft 22 can be inserted through the through hole 16 of the guide sleeve 15, so that the first end of the rotating shaft 22 is located inside the watch case 10 and the second end of the rotating shaft 22 is located outside the watch case 10. The second waterproof gasket 18 is disposed between the gap between the rotating shaft 22 and the inner end face of the guide sleeve 15. When the rotating shaft 22 is in the first state and the rotating blade 23 is received in the receiving groove 14, the inner end face of the rotating blade 23 is in contact with the outer end face of the guide sleeve 15. The size of the receiving groove 14 is adapted to the size of the rotating blade 23; when the rotating shaft 22 is in the first state, the rotating blade 23 is received in the receiving groove 14. Thus, when the flight mechanism 2 is not working, the rotating blade 23 does not affect the user's wearing and daily use of the anti-loss watch. When the rotating shaft 22 is in the second state, the second end of the rotating shaft 22 is far from the rotating electric machine 21, and the rotating blade 23 is far from the receiving groove 14.

[0042] In some embodiments, the flight mechanism 2 further includes a spring assembly 25. The spring assembly 25 may include a first spring 251, a second spring 252, and a limiting member 253. Both the first spring 251 and the limiting member 253 are disposed within the watch case 10. The limiting member 253 is fixed on the outer peripheral surface of the rotating shaft 22. The first spring 251 is sleeved on the rotating shaft 22, and two ends of the first spring 251 respectively abut against the limiting member 253 and the guide sleeve 15. When the rotating shaft 22 is in the first state, the first spring 251 is in a natural state; when the flight mechanism 2 is about to enter the working state and the rotating shaft 22 is switched from the first state to the second state, the rotating motor 21 drives the second end of the rotating shaft 22 away from the rotating motor 21. The limiting member 253 cooperates with the inner end surface of the guide sleeve 15 to compress the first spring 251, and the first spring 251 is held in the compressed state by the acting force of the rotating motor 21 driving the telescopic movement of the rotating shaft 22. When the flight mechanism 2 finishes working and the rotating motor 21 no longer applies a force to the rotating shaft 22, the elastic force generated by the compression of the first spring 251 causes it to return to the natural state, thereby pushing the limiting member 253 and the rotating shaft 22, and enabling the rotating shaft 22 to automatically switch from the second state to the first state, which is convenient and fast. The second spring 252 is sleeved on the rotating shaft 22 and disposed in the outer hole of the through hole 16. When the second spring 252 is in the natural state, one end thereof close to the rotating blade 23 is closer to the inner end surface of the rotating blade 23 than the outer end surface of the guide sleeve 15. When the rotating shaft 22 switches from the second state to the first state, the second spring 252 can buffer the rotating blade 23 to prevent the rotating blade 23 from being damaged when the elastic force of the first spring 251 causes the rotating blade 23 to approach the receiving groove 14. When the rotating shaft 22 is in the first state and the rotating blade 23 is received in the receiving groove 14, two ends of the second spring 252 respectively abut against the step and the rotating blade 23, and the second spring 252 is slightly compressed. During the process of the rotating shaft 22 switching back and forth between the second state and the first state, the elastic force generated by the first spring 251 is greater than the elastic force generated by the second spring 252.

[0043] Referring together Figure 5 , in some embodiments, the main control device 3 may include a main control chip 31 and a calculation unit 32. The main control chip 31 is configured to receive, process, and send control information. The calculation unit 32 is configured to calculate the flight simulation route.

[0044] Referring together Figure 6, in some embodiments, the positioning device 5 includes an ultra-wideband module 51 and a micro sensor 52. The ultra-wideband module 51 can use ultra-wideband technology to achieve ranging, which can reach centimeter-level accuracy and is used to calculate the three-dimensional coordinates of the anti-lost watch in the local coordinate system, so as to determine the real-time position and set position of the watch body 1. The micro sensor 52 is used to analyze the distance between the watch body 1 and surrounding objects, and assist the main control device 3 to calculate and simulate the flight route from the real-time position to the set position. The micro sensor 52 at least includes a lidar for scanning, a vision sensor, and an inertial measurement unit. The main control chip 31 fuses the real-time positioning data identified by the ultra-wideband module 51 and the sensing data of the micro sensor 52, and controls the calculation unit 32 to simulate the autonomous flight of the watch body 1 in the local coordinate system. Then, it controls the flight mechanism 2 to transfer the watch body 1 to the set position in the space to facilitate the wearer's search.

[0045] In some embodiments, the micro sensor 52 may further include an angle sensor, a displacement sensor, and an acceleration sensor. The above sensors cooperate with each other to prevent the anti-lost watch from colliding with surrounding objects during flight.

[0046] The anti-lost search process of the anti-lost watch disclosed in the embodiments of the present utility model is specifically as follows:

[0047] Turn on the Bluetooth system of the mobile terminal;

[0048] Perform an initial pairing between the anti-lost watch and the Bluetooth system of the mobile terminal.

[0049] Among them, the Bluetooth chip 4 of the anti-lost watch is in a working state all the time.

[0050] The mobile terminal identifies whether the anti-lost watch can be searched through the Bluetooth system.

[0051] Among them, this step is performed after the user loses the anti-lost watch;

[0052] If the mobile terminal can search for the anti-lost watch, activate the main control device 3 of the anti-lost watch.

[0053] Among them, if the mobile terminal can search for the anti-lost watch, it means that the anti-lost watch is relatively close to the mobile terminal at this time, and its distance is usually within dozens of meters.

[0054] Start the positioning device to enter the working state; simulate the three-dimensional coordinates of the anti-lost watch in the local coordinate system to confirm the real-time position and set position of the anti-lost watch;

[0055] Calculate and simulate the flight simulation path;

[0056] Start the flight mechanism to transfer the anti-lost watch from the real-time position to the set position.

[0057] If the anti-lost watch is not detected by the mobile device, the Bluetooth chip 4 of the anti-lost watch continuously emits search signals around.

[0058] Among them, if the anti-lost watch is not detected by the mobile device, it means that the anti-lost watch is at a relatively far distance from the mobile device, usually hundreds of meters or even hundreds of kilometers away. Relying on the power of the power module 6 of the anti-lost watch itself, it is difficult to automatically move to a position where the user can easily retrieve it.

[0059] Send a help request to the nearest smart device around the anti-lost watch;

[0060] If the smart device agrees to assist, pair with the smart device, and generate a secret key and a real-time location information data packet;

[0061] Upload the secret key and the real-time location information data packet to the public service cloud server through the smart device; among them, this public service cloud is maintained and associated by the authoritative department to ensure that the privacy data of the anti-lost watch user and the assistant are not illegally obtained and used.

[0062] Download and parse the encrypted data packet; the user can download and decrypt it through the mobile device that has been initially paired with the anti-lost watch.

[0063] Obtain the real-time location of the anti-lost watch on the map and track it.

[0064] In summary, the present utility model discloses an anti-lost watch for wireless communication connection with a mobile device. The anti-lost watch includes a watch body, a flight mechanism for driving the watch body to move, a main control device, a Bluetooth chip for communication connection, and a positioning device; the flight mechanism, the main control device, the Bluetooth chip, and the positioning device are all assembled on the watch body: and the Bluetooth chip, the positioning device, and the flight mechanism are all electrically connected to the main control device. When the anti-lost watch is lost, the main control device can control the flight mechanism to move the watch body to facilitate the user to find the anti-lost watch, or determine the real-time location of the anti-lost watch through the positioning device. The user can obtain the real-time location of the anti-lost watch through the mobile device that has communicated with the anti-lost watch, achieving the anti-lost effect.
