DETAILED DESCRIPTION

[0025] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. The components of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0026] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0027] Anti-lost devices, as portable positioning devices, are widely used in daily life and in the field of monitoring. However, the structural design of existing anti-lost devices has several limitations. The internal space utilization rate of existing anti-lost device housings is low, and the number of components is numerous. This limits the size and shape of the device, making it bulky and heavy. Further miniaturization and lightweighting of the device has become a pressing issue. Furthermore, ensuring that the anti-lost device is securely fixed to the object being used and does not easily fall off, even during strenuous exercise or daily use, is also a challenge that needs to be addressed.

[0028] like Figures 1 to 5 As shown, the anti-lost device of the present application adopts an ultra-small design. The width of the product is smaller than the width of most glasses' temples and weighs only 2g. It includes a shell 1, a cavity space and a buzzer 3. The cavity space is arranged inside the shell 1. The multiple circuit boards 2 are designed and manufactured as a whole. During assembly, the multiple circuit boards 2 are folded to form a cavity space. The buzzer 3 is electrically connected to the circuit board 2 and placed in the cavity space to ensure the stability and functionality of the buzzer 3. By designing the multiple circuit boards 2 as a whole and folding them together, a cavity space is formed to accommodate the buzzer 3. Therefore, through this design, the problem of low utilization rate of the internal space of the anti-lost device shell 1 is effectively solved, so that the internal space of the anti-lost device is fully utilized, and the size and weight of the device are significantly reduced.

[0029] Specifically, the inventors first considered the complex internal structure and low space utilization of traditional anti-lost devices and decided to improve space utilization by optimizing the circuit board design. After multiple experiments and improvements, they ultimately settled on a solution that designed multiple circuit boards 2 as a single unit and folded them together to form a cavity, effectively solving the aforementioned problem.

[0030] As an embodiment, the circuit board 2 includes: a Bluetooth chip circuit board 21 for realizing wireless communication function, a battery protection chip circuit board 22 for protecting the battery 6 from overcharging or over-discharging, a charging circuit board 23 provided with a metal sheet for an external charging spring pin to press against the battery 6 to realize the charging function of the battery 6, and a Bluetooth antenna circuit board 24 for realizing wireless signal transmission. By integrating these functional circuit boards together, the internal space of the shell 1 is effectively utilized, the space utilization rate is improved, the number of components is reduced, the device structure is more compact, and miniaturization and lightweight are facilitated; and the Bluetooth antenna circuit board 24 is placed at the top position of the anti-lost device, and the buzzer 3 is placed at the head position of the anti-lost device to realize the separation of the battery 6 and the Bluetooth antenna circuit board 24. Since the battery 6 is metal, the use of this separation structure will not affect the Bluetooth signal of the anti-lost device, and can also enhance the Bluetooth signal.

[0031] The buzzer 3 is fixed on the inner surface of the Bluetooth chip circuit board 21, and a sound transmission hole is opened at the opening position of the shell 1 corresponding to the cavity space to achieve the effect of transmitting sound inside the anti-lost device.

[0032] As an implementation method, the corresponding Bluetooth chip CPU is responsible for processing the Bluetooth control command information sent by the mobile phone app, such as the shutdown command, and adopts low-power Bluetooth wireless technology. Similar to TWS headphones, the product radiation frequency is very small and the transmission power is only 0dBm (the Bluetooth protocol is from -40dBm to 10dBm), so there is no need to worry about radiation problems.

[0033] Furthermore, the present application proposes that the anti-lost device also includes a circuit terminal 4, which is provided with the multiple circuit boards 2, which provide the core functional modules of the anti-lost device; a battery terminal 5, which is used to install a battery 6; wherein one of the circuit boards 2 (preferably a Bluetooth chip circuit board 21) extends to form a protective plate 7, which is connected to the battery electrodes and covers the outside of the battery 6 to protect the battery 6. These technical features work together to ensure the compactness and stability of the anti-lost device.

[0034] Preferably, the design of the protective plate 7 can be customized according to the size and shape of the battery 6 to ensure optimal coverage and protection. The protective plate 7 can also be integrated with a temperature sensor to monitor the operating temperature of the battery 6, further improving the safety and stability of the device.

[0035] Furthermore, the circuit terminal 4 and the battery terminal 5 are both block-shaped, and the circuit terminal 4 is thicker than the battery terminal 5, and the battery terminal 5 is longer than the circuit terminal 4; a smooth transition section is provided between the circuit terminal 4 and the battery terminal 5.

[0036] The blocky structure of the circuit end 4 facilitates clamping and charging with an external charging clip. The smooth transition section ensures structural stability and allows the elastic silicone ring 8 to be tightly clamped. Through these designs, the silicone ring 8 can more firmly fix the anti-loss device to the temple of the glasses, making it difficult to fall off even during strenuous exercise or daily wear, thus solving the problem of the anti-loss device being unstable.

[0037] Furthermore, the cross section of the silicone ring 8 is in the shape of an 8, wherein an O-ring is clamped on the smooth transition section.

[0038] The silicone ring 8 is made of a material with elasticity and wear resistance to ensure stability and durability in long-term use. The surface of the silicone ring 8 can be further processed, such as adding a frosted design to enhance friction, thereby further improving the stability and anti-slip performance of the anti-lost device. It can be firmly fixed on the smooth transition section and the temple of the glasses of the anti-lost device, with an O-ring clamp on the smooth transition section and another slender O-ring clamp on the temple of the glasses, ensuring that the anti-lost device will not fall off easily during use. The 8-shaped cross-sectional design of the silicone ring 8 increases its stability and connectivity, especially during strenuous exercise or daily wear, and can effectively prevent the anti-lost device from falling off, and the silicone ring 8 will not block the metal sheet on the anti-lost device, so it will not affect the charging function. In addition, a texture design can be added to the surface of the silicone ring 8 to further enhance friction.

[0039] Existing anti-loss devices are often difficult to securely fasten to the temples of glasses, and are prone to loosening or falling off, especially during strenuous exercise or daily wear. This not only affects the device's anti-loss function, but can also lead to the loss of the device itself, resulting in additional economic losses. Therefore, designing a fixing structure that can securely fasten without affecting user comfort has become a major challenge in the design of anti-loss devices. The present invention solves another key problem of the present invention: the fixing method of the anti-loss device, through the structural design of the above-mentioned gradual smooth transition section and the matching silicone ring 8 of the clamp.

[0040] Furthermore, the present application also proposes that a step slot 9 is provided at the top of the housing 1 , and the step slot 9 is used to match and secure the Bluetooth antenna circuit board 24 .

[0041] The housing 1 of the anti-lost device is topped by a cover. The inner surface of the cover features a stepped slot 9 that mates with the Bluetooth antenna circuit board 24, securing it and the multiple circuit boards 2 together. This ensures the overall stability of the internal structure and mitigates potential wobbling during use. This design ensures the device maintains excellent structural stability in a variety of environments. Placing the Bluetooth antenna circuit board 24 at the top allows for efficient use of the internal space of the housing 1, reduces the number of components, and makes the device more compact and lightweight.

[0042] As for the implementation of the stepped slot 9, injection molding can be used to form a stepped structure on the top of the housing 1, ensuring a precise fit with the Bluetooth antenna circuit board 24. Furthermore, the depth and width of the slot can be adjusted based on the dimensions of the Bluetooth antenna circuit board 24 to achieve optimal securing. This design not only improves the overall structural stability of the anti-lost device but also enhances its reliability in actual use. As an alternative implementation, the stepped slot 9 can be fixed with adhesive.

[0043] Furthermore, the present application also proposes an anti-loss system, including the anti-loss device and a mobile terminal as described above, wherein the mobile terminal is connected to the anti-loss device via wireless communication, and the wireless communication method includes but is not limited to Bluetooth, Wi-Fi or NFC, for realizing location tracking, anti-loss reminder and other functions.

[0044] As an implementation method, the mobile terminal is a mobile phone, and the user can choose to install an app on the phone. When the glasses need to be found, the app will connect to the glasses anti-lost device via Bluetooth and make the device emit a sound with a volume of over 80dB. The Bluetooth connection range exceeds 30 meters. Indoors, even if the glasses fall under the sofa, the device can be easily called through the app, and the device will emit a beeping sound, allowing the user to quickly find the device. To extend the product lifespan, the anti-lost device adopts a rechargeable design. A single charge can be used for two months, and the app will remind the user to charge when the battery is low.

[0045] Furthermore, in order to realize the location tracking and anti-lost reminder functions, the anti-lost device can be integrated with a GPS module to transmit the location information to the mobile terminal through wireless communication. The mobile terminal processes and displays the location information through the APP and issues a reminder when the anti-lost device exceeds the set range.

[0046] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

The content of this specification should not be understood as limiting the present invention.
