Description

Technical Field

[0001] This utility model relates to the field of wearable devices, specifically a children's smartwatch with good waterproof performance. Background Technology

[0002] As a significant branch of wearable devices, smartwatches have experienced explosive growth in the global market in recent years. According to statistics from International Data Corporation (IDC), global smartwatch shipments exceeded 180 million units in 2024, representing a year-on-year increase of 23%. These devices integrate functions such as heart rate monitoring, sleep analysis, GPS positioning, and mobile payment, becoming an important terminal for modern people's health management and life services. With technological iterations, the waterproof performance of smartwatches has been continuously improved, with mainstream products generally reaching an IPX8 waterproof rating, capable of supporting immersion in 1.5 meters of water for 30 minutes. However, current waterproof technology is mainly designed for daily use by adults and has not yet fully considered the special needs of children.

[0003] As an important part of the niche market, children's smartwatches accounted for 18.7% of the market share in 2024. Besides basic location monitoring functions, these products also need to cater to the active nature of children. Surveys show that 76% of parents reported their children playing in water, and 43% of children's smartwatch malfunctions were due to water damage.

[0004] Currently, the industry primarily addresses waterproofing issues through the following methods: employing a composite structure of silicone sealing rings and nano-coatings, which provides short-term waterproofing but lacks long-term durability; adding pressure balancing valves to alleviate internal and external pressure differences but potentially introducing new water ingress channels; and increasing casing strength, leading to increased product weight and affecting wearing comfort. While these solutions meet IPX8 standards in laboratory environments, they can still cause malfunctions in real-world scenarios where children frequently come into contact with water (such as handwashing, showering, and swimming pool play). According to data from third-party testing agencies, children's watches have an average failure period of only 6-8 months in cyclic testing simulating daily use environments. The existing waterproofing performance of smartwatches remains insufficient, especially failing to meet the needs of children. Utility Model Content

[0054] Working Principle: Regarding the watch straps, both the first strap 2 and the second strap 3 are made of flexible silicone. Silicone has excellent elasticity, allowing the straps to naturally bend and fit snugly to the wrist without causing pressure, ensuring comfort. Furthermore, various vibrant colors can be created by adding different dyes during manufacturing, catering to children's color preferences. Its natural waterproof properties mean that children can wear the watch even when washing their hands or playing in water without worrying about damage from moisture, unlike leather straps. The smooth surface of silicone also makes it easy for stains to adhere, facilitating daily cleaning and maintenance. For the dial, the unibody waterproof casing 4 is made of insulating materials such as engineering plastics or zirconium oxide, effectively avoiding the oxidation and magnetization issues associated with metal materials, ensuring the watch's durability and the stability of its internal electronic structure. The dial 1 uses wireless charging, preventing magnetization caused by materials like stainless steel from affecting the internal electronic structure. The hydrophobic film 7 on the outer side of the touch display screen 6 effectively prevents water from directly contacting the screen, avoiding liquid adhesion to the surface and improving the user experience. The circumferential cap 8 works in conjunction with the hydrophobic film 7 to make the surface smoother, while protecting the edges of the hydrophobic film 7 and preventing it from loosening or falling off due to lateral force or contaminant entry, thus significantly improving waterproof performance. Even without the hydrophobic film 7, a regular waterproof membrane can provide some waterproofing. The screen support structure 9 on the inner side of the touch display screen 6 includes an inner convex ring 10 and a support block 12. The support block mounting groove 11 on the inner convex ring 10 engages with the support block 12 to provide stable support for the touch display screen 6. A first anti-magnetic partition 13 is located on the side of the inner convex ring 10 facing away from the support block mounting groove 11. This partition isolates the wireless charging magnetic field from affecting the internal electronic structure, and its thickness is designed to be slightly thin to prevent blocking radio electromagnetic signals. In the internal electronic structure, the charging plate 17 is located at the bottom of the integrated waterproof casing 4, and a wireless charging coil is installed on it. When it is near the wireless charger, it uses the principle of electromagnetic induction to transfer electrical energy and charge the watch. The second anti-magnetic barrier 18 above the charging plate 17 also serves to isolate magnetic fields and prevent the wireless charging magnetic field from interfering with other internal electronic components. The circuit board 16, which is fixed by multiple circuit board fixing posts 19, integrates electronic circuit structures such as computing chips, cellular network chips, GPS positioning chips, and storage units. The computing chip is responsible for data processing and calculation, realizing various smart functions of the watch; the cellular network chip connects to the cellular network, enabling the watch to access the Internet, obtain time information, and realize smart functions such as making calls, sending and receiving messages, and online learning; the GPS positioning chip uses satellite positioning technology to obtain the real-time location information of the watch, making it convenient for parents to know the location of their children at any time. The battery 15 uses a polymer lithium-ion battery to provide stable power support for the operation of the entire watch. It is electrically connected to the circuit board 16 and the charging plate 17 to ensure the normal transmission and distribution of electrical energy.
