The above described features and advantages of the present invention will become more apparent and understood from the following description.

1 to 7 are partial cross-sectional views showing a manufacturing process of a charging structure of a smart ball according to an embodiment of the present invention. Referring first to FIG. 1, first, the wireless charging induction coil 11 is electrically connected to the sensor 12, for example, by soldering, and is electrically connected to a battery (not shown) in the sensor 12, for example. For example, the battery (not shown) is, for example, a lead storage battery, a nickel cadmium battery, a nickel hydrogen battery, a lithium ion battery, or a lithium ion polymer battery, which is not limited in the present invention. Next, the wireless charging induction coil 11 and the sensor 12 electrically connected to each other are placed in a sealing mold (not shown), and the encapsulant 13 is injected into a sealing mold (not shown) to coat each other. The wireless charging induction coil 10 and the sensor 12 are electrically connected. After the encapsulated colloid 13 is cured and formed, the encapsulant 13 and the wireless charging induction coil 11 and the sensor 12 covered by the encapsulant 13 are taken out. The encapsulant 13 can be an epoxy, and the sensor 12 is, for example, a tracking sensor, an orientation sensor, a collision sensor, a gyroscope, an accelerometer, or a gravity sensor.

Next, referring to FIG. 2, a heat-resistant paint is sprayed on the periphery of the encapsulant 13 to form a heat-resistant layer 14 covering the encapsulant 13, wherein the sensor 12 (and the wireless charging induction coil 11) and the heat-resistant layer 14 are respectively located in the encapsulant. 13 inside and outside. The heat resistant layer 14 can be used to prevent the wireless charging induction coil 11 and the sensor 12 from being burnt or damaged by high temperatures in subsequent fabrication steps. So far, the fabrication of the sensing package structure 10 has been substantially completed.

Next, referring to FIG. 3 and FIG. 4 , an inner tube layer 21 is provided. The inner tube layer 21 has a receiving groove 22 for the sensor 12 to face the bottom surface 23 of the receiving groove 22 to place the sensing package structure 10 into the receiving groove 22 . Inside. The inner tube layer 21 also has a first surface 24 that connects the accommodating grooves 22, wherein the first surface 24 is parallel to the bottom surface 23, and the second surface 10a of the sensing package structure 10 exposed to the accommodating groove 22 is flush with the first surface 24 . Next, referring to FIG. 5, a wound layer 25 is formed on the inner layer 21, and the wound layer 25 can be attached to the inner layer 21 by glue or other adhesive material. Generally, the material of the inner tube layer 21 may be rubber, and the material of the wound layer 25 may be nylon yarn. Further, the winding layer 25 covers and adheres to the inner tube layer 21 and covers the receiving groove 22 and the sensing package structure 10 located in the receiving groove 22. On the other hand, under the premise that the second surface 10a of the sensing package structure 10 is flush with the first surface 24, it contributes to improving the flatness of the winding layer 25 attached to the inner tube layer 21.

Next, referring to FIG. 6, the outer layer 26 is formed on the winding layer 25. The material of the outer layer 26 may be dermis, synthetic leather or rubber, which may be covered by a vulcanization process and attached to the winding layer 25, wherein the outer layer 26 and the inner tube layer 21 are located on opposite sides of the wound layer 25, respectively. Since the heat-resistant layer 14 is wrapped around the periphery of the wireless charging induction coil 11 and the sensor 12, the high temperature during the vulcanization process does not cause damage to the wireless charging induction coil 11 and the sensor 12. Finally, referring to FIG. 7, the ball skin 27 is covered and attached to the casing layer 26, wherein the ball skin 27 and the winding layer 25 are respectively located on opposite sides of the casing layer 26.

The sensor 12 is configured to sense the motion state of the ball 20, and the sensor 12 can synchronously transmit the detected signal to the external signal receiver during the movement of the ball 110, so that the external signal receiver receives the signal according to the reception. The resulting signal analyzes the flight distance, the degree of compression, the speed of movement, or the orientation of the sphere 20.

The wireless charging induction coil 11 can be sensed with an external wireless discharge induction coil (not shown) to charge a battery (not shown) in the sensor 12. In practice, the battery is configured to supply the electrical energy required for operation of the sensor 12. On the other hand, the winding layer 25 of the ball 20 can be used to ensure that the inner tube layer 21 has toughness and firmness, and the spherical body 20 is less likely to be deformed. In addition, the wrap layer 25 allows the bounce of the ball 20 to be regular and enhances the rotational stability of the ball 20 when it is flying.

In the present embodiment, the first distance D1 between the wireless charging induction coil 11 and the outer surface 28 of the ball 20 is smaller than the second distance D2 between the sensor 12 and the outer surface 28 to improve the efficiency of wireless charging, ie The distance between the wireless charging induction coil 11 and an external wireless discharge induction coil (not shown) placed on the outer surface 28 of the ball 20 is reduced.
