Description

TECHNICAL FIELD

[0001] The present application relates to the field of sports goods, in particular to an elastic ball with a communication sub-station and a production method thereof. BACKGROUND

[0002] In children's education, ball games such as football are one of the ways to promote children to exercise. Ball games have the advantages of promoting children's hand-eye coordination, promoting the development of children's movement coordination ability, improving children's judgment ability, and improving children's team cooperation spirit.

[0003] When children play ball games, each child is equipped with a football. Since different children have different preferences for ball games, when children like ball games, they will constantly kick and chase footballs to run, so that the children's exercise amount can meet the standard. When children do not like ball games, the number of times of kicking footballs will be significantly reduced, and the distance of chasing footballs will also be greatly reduced, so that the children's exercise amount is insufficient.

[0004] To assist in determining whether the exercise amount of children playing ball games meets the standard, the ball body is hollow, a communication sub-station is installed in the ball body to position the ball movement stroke, and a sheet-shaped plane or a strip-shaped support is used to support the communication sub-station. The support structure supports the "force point" at a certain point or a certain line on the inner wall of the ball body, so that the bouncing direction of the ball body adds an additional torque when doing elastic action, generates an additional angular momentum, causes the ball body to bounce out of order, and thus cannot realize the normal bouncing of the elastic ball.

DETAILED DESCRIPTION

[0055] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

The foamed ball body 1 has a certain elasticity, which is convenient for children to use in sports.

[0059] The communication sub-station 2 is wirelessly connected with a communication main station, the ball body 1 drives the communication sub-station 2 to move when moving, the communication sub-station 2 transmits the moving stroke of the ball body 1 to the communication main station, the movement of each communication sub-station 2 is displayed on the communication main station, so as to conveniently assist in judging whether the children's sports amount is up to the standard. And in the solid elastic foamed ball body 1, the vibration effect of the communication sub-station 2 located at the ball center is supported by being "uniformly and diffusely" supported to the whole ball surface, so that the force transmission and the bouncing effect are the same as those of the traditional hollow elastic ball body without the communication sub-station 2, and thus the ball body 1 has the positioning function while being able to bounce normally.

[0060] The foamed outer layer 12 is composed of an inner foamed layer 121 and an outer foamed layer 122, the inner foamed layer 121 is wrapped on the foamed ball core 11, the outer foamed layer 122 is wrapped on the inner foamed layer 121, and the density of the inner foamed layer 121 is less than the density of the outer foamed layer 122 and the foamed ball core 11. The smaller density of the inner foamed layer 121 makes the hardness of the inner foamed layer 121 less than the density of the outer foamed layer 122 and the foamed ball core 11, when the child kicks the ball 1, the softer inner foamed layer 121 can increase the elasticity, so that the ball 1 is more elastic. The larger hardness of the foamed ball core 11 is beneficial to wrapping and fixing the communication sub-station 2, so that the communication sub-station 2 is more stable in the ball 1.

[0061] A plurality of petal-shaped air bags 4 are installed in the ball 1, the plurality of air bags 4 are combined to form a hollow spherical body and are wrapped on the inner foamed layer 121, and the outer foamed layer 122 is wrapped on the plurality of air bags 4 and limits and fixes the plurality of air bags 4.

[0062] The ball 1 is provided with a charging interface 3 and a connecting line 6, the communication sub-station 2 is provided with a small lithium battery, one end of the connecting line 6 is electrically connected with the small lithium battery in the communication sub-station 2, the connecting line 6 passes through the foamed ball core 11, the inner foamed layer 121, the gap between adjacent air bags 4 and the outer foamed layer 122, the charging interface 3 is installed on the surface of the outer foamed layer 122, and the other end of the connecting line 6 away from the communication sub-station 2 is electrically connected with the charging interface 3. The charging interface 3 and the connecting line 6 can charge the communication sub-station 2, thereby facilitating the repeated use of the ball 1.

[0063] Referring to Figure 1 and 2 , the connecting line 6 is made of a positive line 61 and a negative line 62 which are spirally wound, and the connecting line 6 is in a spiral shape in the ball 1. The connecting line 6 made of the spirally wound positive line 61 and negative line 62 increases the structural strength of the connecting line 6, and at the same time, the connecting line 6 is in a spiral shape in the ball 1, so that the connecting line 6 has a certain amount of expansion and contraction in the ball 1, when the ball 1 is kicked and deformed, the connecting line 6 can expand and contract with the ball 1, thereby preventing the connecting line 6 from being pulled off in the ball 1.

[0064] The implementation principle of the embodiment 1 of the application is that the ball 1 drives the communication sub-station 2 to move when moving, the communication sub-station 2 transmits the moving stroke of the ball 1 to the communication master station, the movement of each communication sub-station 2 is displayed on the communication master station, thereby facilitating the auxiliary judgment of whether the child's exercise amount meets the standard; and the solid elastic foam ball 1 is used, so that the ball 1 has positioning function and can normally bounce.
