Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of children's mobile phones, specifically a child's small mobile phone with anti-loss and positioning functions. BACKGROUND

[0002] In today's fast-paced society, children's small mobile phones have become an important tool for parents to monitor their children. These small mobile phones usually have basic calling and messaging functions, and more importantly, they are equipped with a positioning system that allows parents to know the child's location at any time. This greatly alleviates parents' concerns about the safety of their children, whether they are going to school alone, playing in the park, or going out with friends. Parents can track their children's whereabouts through mobile phone positioning.

[0003] Current children's small mobile phones on the market still have many shortcomings in terms of anti-loss and positioning functions. In terms of anti-loss design, many children's small mobile phones are simply equipped with a lanyard or buckle, which is far from enough for lively and active children. During running and playing, the lanyard is easy to break and the buckle may come off, causing the phone to be easily lost.

[0004] The existing device mainly uses a smart watch as a small mobile phone for children to use. The existing technology is similar to a child's small mobile phone with anti-loss and positioning functions, with a structure disclosed in CN212785441U, which includes a elastic band, the outer surface of the elastic band is fixedly connected with a placing box, the inside of the placing box is rotatably connected with a flip cover, the top of the placing box is fixedly connected with a connecting plate, the front end of the connecting plate is rotatably connected with a moving plate, and the inside of the placing box is provided with a clamping device. The child's small mobile phone with anti-loss and positioning functions can place the mobile phone body in the placing box of the watch, effectively preventing the loss of the child's mobile phone and reducing the emotional burden of parents. However, there are still areas that can be optimized for this device.

[0005] The existing device mainly adopts a storage box to place the small mobile phone, and various electronic elements are not matched in the storage box, so that the storage box is difficult to correspond to the mobile phone body, thereby causing the storage box to be inconvenient for the mobile phone body to be positioned and monitored. Secondly, part of the device does not set the vibration module, so that part of the storage box is difficult to generate a vibration signal and transmit to the wrist of the user, thereby causing the mobile phone body to be inconvenient for the risk of loss to be prewarned. Furthermore, the wristband of part of the device is worn relatively loose, so that part of the device is difficult to tighten the wristband to ensure that the bottom of the storage box is close to the wrist of the user, thereby causing the wrist of the user to be difficult to clearly sense the vibration information. Finally, part of the device mainly adopts two groups of control switches to open and close the tightening mechanism and the vibration mechanism, so that part of the device is difficult to supply power to the tightening mechanism and the vibration mechanism at the same time, thereby causing the tightening mechanism and the vibration mechanism to be inconvenient for synchronous starting, reducing the working efficiency and practicability of the device, and therefore, in order to solve the above problems, a child small mobile phone with positioning function is provided.
