[0031] Counterweight is arranged in base 201, which is used to improve the stability of base 201, and rubber pad is arranged on the lower side of base 201, which is used to increase the friction between base 201 and the ground of the playing field.

[0032] Football body 1 includes inner bag 11, air nozzle 12, nylon fiber rope 13, motion sensor 14 and wireless charging coil 15; inner bag 11 is installed on the inner side of football body 1; air nozzle 12 is installed on football body 1, and air nozzle 12 penetrates the outer layer of football body 1 and is communicated with inner bag 11; a plurality of nylon fiber ropes 13 are installed on inner bag 11; one motion sensor 14 is commonly connected at the end of all nylon fiber ropes 13 away from inner bag 11; wireless charging coil 15 is installed on the inner side of inner bag 11.

[0033] The air nozzle 12 and the wireless charging coil 15 are oppositely arranged based on the central symmetry axis of the football body 1, so as to improve the balance of the football body 1.

[0034] The air nozzle 12 is provided with a counterweight, so that the rotational inertia of the football body 1 is uniformly distributed.

[0035] Further comprising a ring-shaped frame 301, a connecting rod 302 and an arc-shaped rod 303; the ring-shaped frame 301 is detachably connected to the base 201; the ring-shaped frame 301 is rotatably connected with two connecting rods 302; one torsion spring is fixedly connected to the connecting rod 302 at the connection with the ring-shaped frame 301; one arc-shaped rod 303 is fixedly connected to the end of each connecting rod 302 away from the ring-shaped frame 301.

[0036] Further comprising an elastic member 304; two elastic members 304 are connected between all the arc-shaped rods 303, and the elastic member 304 is a spring.

[0037] The diameter of the exhaust hole 2071 is smaller than that of the flow guide hole 2021, so as to make the eardrum 207 be lifted upward and increase the flow rate of the gas.

[0038] Further comprising an inclined pipe 208; an inclined hole 2011 is formed in the base 201, and the inclined pipe 208 is fixedly connected in the inclined hole 2011; the inclined pipe 208 is fixedly connected with and communicates with the conduit 205.

[0039] Before use, the football body 1 is inflated by manually filling air into the inner container 11 of the football body 1 through the air nozzle 12, so that the air pressure of the inner container 11 of the football body 1 reaches a preset air pressure value, so as to ensure the normal use of the football body 1, and the motion sensor 14 is suspended and fixed at the center of the inner container 11 through the nylon fiber rope 13, so as to realize that the electronic module of the motion sensor 14 is encapsulated in a multi-directional buffer structure core, the core is symmetrically anchored on the inner wall of the inner container 11 of the football body 1 through the flexible connecting piece (i.e. the nylon fiber rope 13), so as to ensure that the electronic module of the motion sensor 14 can be buffered under impact in any direction, the center of gravity is stable, and the inner container 11 of the football body 1 is not affected.

[0040] When the football body 1 is in a motion state, the kicking and landing impact, the motion direction change are accurately recorded by the motion sensor 14, so as to obtain the motion trajectory of the football body 1, and the self-rotation and the rotation state of the arc ball are accurately captured by the motion sensor 14, so as to obtain the radian of the passing trajectory, the landing accuracy and the initial speed, and the passing quality is evaluated by combining the algorithm, and the offside scene is reconstructed in the virtual scene by combining the player GPS data, so that the motion trajectory of the football body 1 and the motion trajectory of the player are realized 3D visualization, and the fairness and the watchability of the game are improved.

[0041] When the football body 1 needs to be charged after a long time of use, the football body 1 is placed on the base 201 and the wireless charging seat 202 by artificial, as shown, the football body 1 is limited by the base 201 and the wireless charging seat 202, so that the football body 1 remains stable during charging, and the wireless charging seat 202 is magnetically connected with the wireless charging coil 15 of the football body 1, so that the football body 1 is adsorbed on the wireless charging seat 202, and the wire on the wireless charging seat 202 is connected with the external power supply, so as to realize wireless charging of the football body 1, and improve user experience. Figure 3

[0042] Since the football body 1 is charged at the side of the football field, the football body 1 is easily affected by external wind force during charging, further increasing the risk of disconnection between the wireless charging coil 15 in the football body 1 and the wireless charging seat 202, and increasing the risk of falling of the football body 1 from the wireless charging seat 202. The annular frame 301 is inserted into the base 201 by artificial, and the annular frame 301 is locked on the base 201 by bolt, so that all the connecting rods 302, the arc-shaped rods 303 and the elastic members 304 are located outside the football body 1, so as to limit the football body 1, and reduce the risk of disconnection and falling of the football body 1 from the wireless charging seat 202.

[0043] It should be noted that since the football body 1 is used, some impurities such as grass clippings and soil will inevitably adhere to the outer surface of the football body 1, especially in a relatively humid environment of the football field and in rainy weather, which will further cause unstable physical contact between the football body 1 and the wireless charging coil 15, and then cause temporary separation between the wireless charging coil 15 and the wireless charging seat 202, resulting in charging interruption.

[0044] To solve the above problems, after the football body 1 is placed on the wireless charging seat 202, the micro-pump 204 is started to supply gas to the conduit 205, the gas flows into the air pipe 206 through the conduit 205, and blows to the eardrum 207 through the air pipe 206 and the flow guide hole 2021. Since the diameter of the exhaust hole 2071 in the eardrum 207 is smaller than the diameter of the flow guide hole 2021, when the airflow blows to the eardrum 207, the eardrum 207 will arch upward, as shown in Figure 4 ​As shown, and the football body 1 is lifted by the eardrum 207, so that the football body 1 is moved upward to separate from the wireless charging seat 202, so that the wireless charging coil 15 in the football body 1 is disconnected with the wireless charging seat 202, and the gas discharged through the exhaust hole 2071 blows to the football body 1 from bottom to top, and when the gas enters the guide pipe 205, the gas flows to the inclined pipe 208 through the guide pipe 205 and is sprayed from the inclined hole 2011, so that the gas blows to the side wall of the football body 1 in an inclined upward manner, and the gas discharged through the exhaust hole 2071 and the gas discharged through the inclined hole 2011 blow to the football body 1 together, so that the football body 1 slowly rotates, and the grass clippings, soil and other impurities adhered to the outer surface of the football body 1 are blown away by the gas, thereby improving the stability of the connection between the football body 1 and the wireless charging seat 202 in the subsequent charging process, thereby reducing the possibility of temporary disconnection between the wireless charging coil 15 and the wireless charging seat 202, resulting in interruption of charging.

[0045] When the grass clippings, soil and other impurities adhered to the outer surface of the football body 1 are blown away by the gas, in order to improve the cleaning effect on the football body 1, the micro air pump 204 is controlled to start operation to increase the gas supply, so that the gas pressure in the guide pipe 205 increases, and the gas flow intensity blowing to the outer surface of the football body 1 through the air pipe 206 and the inclined pipe 208 increases, so that the football body 1 moves upward to separate from the eardrum 207 and suspends in the air, and the upper part of the football body 1 contacts all the arc-shaped rods 303 and the elastic members 304 and squeezes all the arc-shaped rods 303, so that the two connecting rods 302 rotate and twist the torsion springs between the connecting rods 302 and the ring-shaped frame 301, and stretch the two elastic members 304, so that the football body 1 rotates and rubs with all the arc-shaped rods 303 and the elastic members 304, thereby scraping the grass clippings, soil and other impurities adhered to the surface of the football body 1 through the friction between the football body 1 and all the arc-shaped rods 303 and the elastic members 304. When the football body 1 rubs with the elastic members 304, the contact area of the elastic members 304 with the football body 1 is smaller than the contact area of the arc-shaped rods 303 with the football body 1, so that the resistance of the football body 1 when rotating is reduced to ensure that the football body 1 can still rotate and still scrape the grass clippings, soil and other impurities adhered to the surface of the football body 1 through the elastic members 304, thereby improving the cleaning effect on the football body 1 and further improving the user's experience.

[0046] Embodiment two: based on embodiment one, according to Figure 3 and Figure 7 As shown, it further comprises a fixed block 305 and a pin 306; the outer ring surface of the base 201 is equally fixed with three fixed blocks 305; each fixed block 305 is dampedly rotationally connected with a pin 306.

[0047] It should be noted that the initial state of all the pins 306 is horizontal with the base 201, when the base 201 is placed on the turf in the football field for use, due to the small friction between the turf and the base 201, plus the influence of external wind, and then easily lead to the base 201 tilt, unstable, by artificial rotation of all the pins 306, so that all the pins 306 by the initial horizontal state into the vertical downward state, as shown in Figure 7 All the pins 306 are inserted into the turf, and the base 201 is moved downward to press the turf, so that the base 201 is closely attached to the turf, thereby increasing the friction between the base 201 and the turf, and increasing the stability of the base 201 by inserting all the pins 306 into the turf, thereby reducing the possibility of the base 201 tilting, so that the base 201 is placed on the turf more stably, to ensure the normal use of the base 201.

[0048] The technical principles of the embodiments of the present application are described above in combination with specific examples. These descriptions are only to explain the principles of the embodiments of the present application, and cannot be interpreted in any way as a limitation on the protection scope of the embodiments of the present application. Based on the explanations here, those skilled in the art can think of other specific embodiments of the embodiments of the present application without creative labor, and these embodiments will fall within the protection scope of the embodiments of the present application.
