With the development of technology, various electronic devices are gradually installed inside the ball. However, the electronic devices inside the ball are easily damaged by impact. Usually, an opening is made on the ball for replacement. However, no matter what kind of opening is made, it will greatly change the characteristics and specifications of the ball itself, resulting in a great difference in its appearance, feel and that of a traditional ball, and the impact resistance is not high. Summary of the Invention

The electronic device is located in the installation space. The inside of the ball inner bladder can be inflated and deflated. When the inside of the ball inner bladder is deflated, a channel communicating with the installation space is formed outside the ball inner bladder, so that the electronic device located in the installation space can be replaced through the channel. When the inside of the ball inner bladder is inflated, the channel can be closed by the inflated ball inner bladder, so that the outside of the ball inner bladder completely covers the electronic device located in the installation space.

Additionally, the term "or" used herein should, depending on the actual situation, possibly include any one or a combination of multiple relevant listed items.

[0026] Please refer to Figures 1 to 2 As shown, an embodiment of the present invention provides an inflatable sphere, which mainly includes a sphere outer skin 1, a sphere inner bladder 2 and an electronic device 3.

[0027] The sphere outer skin 1 wraps the sphere inner bladder 2. The sphere outer skin 1 can be the skin of various balls, such as the skin of a football or a basketball, and can wrap the sphere inner bladder 2 in a pasting manner, and can also wrap the sphere inner bladder 2 partially or entirely in a splicing manner. In addition, the sphere outer skin 1 can be a partially transparent or completely transparent sphere outer skin, and the sphere outer skin 1 does not necessarily have to be transparent.

[0028] The sphere inner bladder 2 can be made of rubber, preferably made of a polymer material with high elasticity and high compressive resistance. For example, it can be made of opaque thermoplastic polyurethane (TPU), or can also be made of transparent TPU, with characteristics such as light weight and durability. An installation space S1 is formed at the center of the sphere of the sphere inner bladder 2 on the outside of the sphere inner bladder 2, and the electronic device 3 is located in the installation space S1. Specifically, the inside of the sphere inner bladder 2 can be inflated and deflated. It can be through an air needle inserted into the air nozzle 21 of the sphere inner bladder 2 to make the inside of the sphere inner bladder 2 inflated and deflated. When the inside of the sphere inner bladder 2 is deflated, a channel S2 is formed on the outside of the sphere inner bladder 2. The channel S2 is configured as a channel for a user's hand to enter, and the channel S2 communicates with the installation space S1, so that the electronic device 3 located in the installation space S1 can be replaced through the channel S2. When the inside of the sphere inner bladder 2 is inflated, the channel S2 can be closed by the inflated sphere inner bladder 2, that is, the channel S2 can be closed by the outer wall of the sphere inner bladder 2, so that the outside of the sphere inner bladder 2 completely wraps the electronic device 3 located in the installation space S1, that is, the outer wall of the sphere inner bladder 2 completely wraps the electronic device 3 located in the installation space S1. Thus, when the inside of the sphere inner bladder 2 is filled with gas, the air pressure can force the outside of the sphere inner bladder 2 to closely adhere to the electronic device 3, providing a buffering and protection effect. And when the gas inside the sphere inner bladder 2 is released, the channel S2 closed on the outside of the sphere inner bladder 2 is opened, and the user can take the electronic device 3 located in the installation space S1 from the channel S2, which is convenient for the user to replace the electronic device 3 or its battery.

[0029] In one embodiment, in cooperation with Figure 3 As shown, the electronic device 3 can be a sensing device 3a. The sensing device 3a includes a sensing unit 31a, a power supply unit 32a and a main control unit 33a. And, the main control unit 33a is electrically connected to the sensing unit 31a and the power supply unit 32a.

[0030] Furthermore, the main control unit 33a may include a main control circuit board 331, and single or multiple microprocessors M, components such as resistors or capacitors may be disposed on the main control circuit board 331. The sensing unit 31a may include an acceleration sensor 311 and an angular velocity sensor 312 disposed on the front or back of the main control circuit board 131. Therefore, the sensing unit 31a can sense the acceleration and angular velocity of the inner ball 2 through the acceleration sensor 311 and the angular velocity sensor 312, so that the main control unit 33a can calculate the ball speed and rotation speed of the inner ball 2 according to the acceleration and angular velocity of the inner ball 2. The power supply unit 32a may include one or more batteries B, and the battery B may be disposed on the front or back of the main control circuit board 131.

The lighting device 3b includes a lighting unit 31b, a power supply unit 32b, and a main control unit 33b. Moreover, the main control unit 33b is electrically connected to the lighting unit 31b and the power supply unit 32b.

[0033] Furthermore, the main control unit 33b may include a main control circuit board 331, and components such as a single or multiple microprocessors M, resistors, or capacitors may be provided on the main control circuit board 331. The light-emitting unit 31b may include a plurality of light-emitting diodes D, and the plurality of light-emitting diodes D are respectively arranged on the front and back sides of the main control circuit board 331, so that the plurality of light-emitting diodes D can emit light in opposite directions simultaneously, making the lamp illumination uniform. The power supply unit 32 may include one or more batteries B, and the batteries B may be arranged on the front and back sides of the main control circuit board 131. Optionally, the battery B may be a button battery, for example. In this embodiment, the light-emitting device 3b may further include a vibration switch 34b electrically connected to the main control unit 33b. The vibration switch 34b may be arranged on the front or back side of the main control circuit board 331, and the vibration switch 34b can be used to sense vibration. When vibration is sensed, the switch can be turned on to control each light-emitting diode D to turn on, and when no vibration is sensed after a preset time, the switch can be turned off to control each light-emitting diode D to turn off, thereby extending the usage time of the battery B. In addition, the main control unit 33b may further have a redundant power supply mode, so that when one of the light-emitting diodes D is damaged, the other light-emitting diodes D will still be lit.

[0034] In one embodiment, the electronic device 3 may be a device integrated with a Figure 3 sensing device 3a and Figure 4 the light-emitting device 3b, that is to say, the electronic device 3 may be a light-emitting device with a sensing function.

[0035] In one embodiment, as shown in Figure 5 coordination, the inner sphere 2 of the inflatable sphere contains a first airbag 2a and a second airbag 2b arranged opposite to each other, and can be inflated and deflated through the first air nozzle 21a and the second air nozzle 21b respectively.

The electronic device 3 is located in the installation space S1, and the inside of the spherical inner bladder 2 can be inflated and deflated. When the inside of the spherical inner bladder 2 is deflated, a channel S2 is formed outside the spherical inner bladder 2, which communicates with the installation space S1, so that the electronic device 3 located in the installation space S1 can be replaced through the channel S1. When the inside of the spherical inner bladder 2 is inflated, the channel S1 can be closed by the inflated spherical inner bladder 2, so that the outside of the spherical inner bladder 2 completely covers the electronic device 3 located in the installation space S1. Therefore, when the inside of the spherical inner bladder 2 is filled with gas, the air pressure can force the outside of the spherical inner bladder 2 to closely contact the electronic device 3, providing a buffering and protection effect, and the appearance and feel of the ball are not much different from those of a traditional ball and it has a high impact resistance.
