Technical Field

[0001] This utility model relates to the field of watch technology, and in particular to a wireless charging watch strap and a watch. Background Technology

[0002] Smart wearable devices, such as smartwatches and smart bracelets, are currently very popular. Their charging methods generally fall into three categories: direct charging via USB interface, charging via metal contact points, and wireless charging. Most existing smartwatches have wireless charging capabilities. A Chinese patent application (application number 202222963580.7) discloses a watch band with wireless charging functionality, comprising a charging case, a first watch band, and a second watch band. The first watch band has a connecting pin, and the second watch band has a connector. The charging case contains a wireless charging coil, and the second watch band contains an FPC board electrically connected to the wireless charging coil. A charging port is located at the end of the FPC board furthest from the charging case. The second watch band has a Velcro hook or loop side near the charging case, and a Velcro loop or loop side away from the charging case. The patent document integrates the FPC board and wireless charging coil into the charging case, but there is no battery in the charging case to power the wireless charging coil. Wireless charging can only be achieved by connecting an external power output port to the charging port on the watch band.

[0003] Furthermore, Chinese patent application number 202220717405.7 discloses a watchband structure and a watch. The watchband structure includes a watchband body and a charging base. The watchband body is connected to the charging base and together they form a closed loop structure. A pair of joints extend from the position on the watchband body where it connects to the charging base. The ends of the joints are provided with detachable connectors for detachable connection to both ends of the watch movement body. The watchband body has a battery compartment and a circuit board. The circuit board is electrically connected to both the battery compartment and the base body. The battery compartment is located on the side of the watchband body facing away from the charging base. A watchband tensioning fastener is provided on the portion of the watchband body between the charging base and the battery compartment. Although this patent discloses that the watchband body has a battery compartment and a circuit board, only one side of the watchband body has a battery compartment, resulting in a small number of battery compartments and a short battery life for wireless charging.

[0004] Additionally, Chinese patent application number 201510300860.1 discloses a watchband-type electronic device, including a watchband and a watch body. The watch body is detachably embedded in a groove in the middle of the watchband. The watchband has a USB interface and a wireless charging transmitting coil, while the watch body contains a rechargeable battery and a wireless charging receiving coil. When the watch body is charging, the USB interface of the watchband is connected to an external power source, the wireless charging transmitting coil of the watchband generates an electromagnetic signal, and the wireless charging receiving coil of the watch body senses the electromagnetic signal and generates a current to charge the battery. The wireless charging transmitting coil is located in the groove in the middle of the watchband, and the USB interface is located at either end of the watchband. The watchband also includes an outer soft rubber and a first connecting flexible circuit board. The wireless charging transmitting coil and the USB interface are both soldered to the first connecting flexible circuit board. The first connecting flexible circuit board, the wireless charging transmitting coil, and the USB interface are encased in the outer soft rubber after being injection molded into inserts. The patent document describes integrating a rechargeable battery and a wireless charging receiver coil into the watch body, resulting in a thicker watch body.

[0005] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

Detailed Implementation To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figures 1 to 3As shown, this utility model provides a wireless charging watch band, which includes a mounting shell 1, a wireless charging coil module 2 (wireless charging component), a circuit board 3, a rechargeable battery 4, a first connecting strap 5, a second connecting strap 6, and two watch band bodies 7. The mounting shell 1 has a recessed mounting cavity 8 in the middle. The wireless charging coil module 2 is embedded in the inner bottom wall of the mounting cavity 8. One watch band body 7 houses the circuit board 3, the battery 4, and a charging port 9, while the other watch band body 7 houses the battery 4. One end of each watch band body 7 is connected to both ends of the mounting shell 1. The charging port 9 and the wireless charging coil module 2... Both the battery 4 and the wireless charging coil module 2 are electrically connected to the circuit board 3. The charging port 9 charges the battery 4 via the circuit board 3. The battery 4 supplies power to the wireless charging coil module 2. One end of the first connecting strap 5 is connected to the end of one watch strap body 7 away from the mounting shell 1, and one end of the second connecting strap 6 is connected to the end of another watch strap body 7 away from the mounting shell 1. The other ends of the first connecting strap 5 and the second connecting strap 6 are detachably connected. Specifically, the watch strap body 7 is arc-shaped or composed of multiple cuboid segments. When the watch strap body 7 is composed of multiple cuboid segments, it is preferable to form it as a single piece from two cuboid segments. Specifically, a charging switch button 18 is provided on the surface of one of the watch strap bodies 7. The charging switch button 18 is electrically connected to the circuit board 3 and is used to control the battery 4 to supply power to the wireless charging coil module 2.

[0023] In use, the wirelessly charging watch body is installed in the mounting cavity 8, and the charging switch button 18 is pressed. The circuit board 3 controls the battery 4 to supply power to the wireless charging coil module 2, which then wirelessly charges the watch body. When it is necessary to charge the battery 4 inside the watch band body 7, the charging connector is inserted into the charging port 9, and the charging connector charges the battery 4. When this wireless charging watch band is worn on the wrist, the two watch band bodies 7 wrap around the forearm and fit as snugly as possible, with the first connecting strap 5 and the second connecting strap 6 connected together. This invention installs the battery 4 and circuit board 3 inside the watch band body 7, making the mounting shell 1 thinner, with a compact structure and beautiful appearance. It avoids the problem of the existing technology requiring the battery 4 to be installed inside the mounting shell 1, which results in a thicker mounting shell 1. This is beneficial for the heat dissipation of the wireless charging coil module 2, battery 4 and circuit board 3. Smartwatches generally have blood oxygen detection functions at the bottom. The thinner mounting shell 1 is conducive to the normal detection of these functions. In addition, each watch band body 7 has a battery 4 installed inside. The large number of batteries 4 helps to increase the battery life of the batteries 4 and extend the time for wireless charging of the watch body.

[0024] Specifically, the inner bottom wall of the mounting cavity 8 is recessed with an embedding hole, and the wireless charging coil module 2 is embedded in the embedding hole.

[0025] Specifically, the charging port has detachable waterproof plugs at 9 points, making it convenient to use and providing good waterproof performance.

[0026] In this embodiment, conductive terminals are provided at both ends of the mounting shell 1, and the two conductive terminals are electrically connected via wires. The conductive terminal at one end of the mounting shell 1 is electrically connected to the wireless charging coil module 2 via a wire, and this conductive terminal is used to electrically connect to the circuit board 3 inside one watch band body 7. The conductive terminal at the other end of the mounting shell 1 is used to electrically connect to the battery 4 inside another watch band body 7. This structure is practical and facilitates the electrical connection between the wireless charging coil module 2 and the circuit board 3, and between the battery 4 and the circuit board 3.

[0027] In this embodiment, a wiring groove 10 is recessed in the inner bottom wall of the mounting cavity 8, and the wire is accommodated in the wiring groove 10. This structure is practical, which is beneficial for the routing and positioning of the wire and reduces the exposure of the wire.

[0028] In this embodiment, the wiring trough 10 is filled with waterproof adhesive, and the wires are embedded in the wiring trough 10 through the waterproof adhesive. This structural design facilitates waterproofing of the wires and prevents them from being exposed. Additionally, when the mounting housing 1 is made of PVC or silicone material, there is no need to fill the wiring trough 10 with waterproof adhesive, and waterproof wires are used.

[0029] In this embodiment, both ends of the mounting shell 1 are provided with protruding first sealing plugs 11, and the two watch strap bodies 7 are each provided with an inwardly recessed receiving cavity 12 on the end face near the mounting shell 1. The battery 4 and / or the circuit board 3 are installed in the receiving cavity 12, and the first sealing plugs 11 can be inserted into the port of the receiving cavity 12. This structural design realizes the modular assembly of the mounting shell 1 and the watch strap body 7, and the first sealing plugs 11 are in close contact with the port of the receiving cavity 12, resulting in good sealing and waterproofing effects.

[0030] In this embodiment, each of the two watch strap bodies 7 has an insertion port 13 on its end face away from the mounting shell 1. A second sealing plug 14 protrudes from one end of the first connecting strap 5 and one end of the second connecting strap 6. The second sealing plug 14 of the first connecting strap 5 is inserted into the insertion port 13 of one watch strap body 7, and the second sealing plug 14 of the second connecting strap 6 is inserted into the insertion port 13 of the other watch strap body 7. This structural design enables modular assembly of the watch strap body 7 with the first connecting strap 5 and modular assembly of the watch strap body 7 with the second connecting strap 6. Furthermore, the second sealing plug 14 is in close contact with the inner wall of the insertion port 13, resulting in good sealing and waterproofing effects.

[0031] In this embodiment, the main body 7 of the watch strap is made of aluminum or aluminum alloy. This structural design makes the main body 7 lightweight, strong, and long-lasting, and is beneficial for producing a watch strap main body 7 with a thinner wall thickness.

[0032] In this embodiment, the first connecting strap 5 has a through hole 15, and a buckle block 16 protrudes from the inner or outer side of the first connecting strap 5. The second connecting strap 6 has multiple buckle holes 17 arranged in a straight line. The through hole 15 is used for the second connecting strap 6 to pass through, and the buckle block 16 is used to engage with one of the buckle holes 17. When this wireless charging watch strap is worn on the forearm, after the second connecting strap 6 passes through the through hole 15, the first connecting strap 5 covers the second connecting strap 6. Then, the buckle block 16 on the first connecting strap 5 engages with the corresponding buckle hole 17 to achieve the connection between the first connecting strap 5 and the second connecting strap 6.

[0033] Of course, the first connecting strap 5 and the second connecting strap 6 can also be detachably connected by a buckle.

[0034] In this embodiment, at least one battery 4 is installed in each watchband body 7. By increasing the number of batteries 4, the battery life of the battery 4 is increased. The battery 4 is arc-shaped or cuboid. The arc of the battery 4 is the same as the arc of the watchband body 7, or the shape of the battery 4 is the same as the shape of the cuboid band segment, which makes it easy to install the battery 4 in the watchband body 7.

[0035] This utility model also provides a watch, including a watch body capable of wireless charging and the aforementioned wireless charging watchband. The watch body is detachably installed in the mounting cavity 8, and the wireless charging coil module 2 can wirelessly charge the watch body. This watch possesses all the beneficial effects of the aforementioned wireless charging watchband, which will not be elaborated further here.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
