Description

TECHNICAL FIELD

The present disclosure relates to the field of baseball technologies, and in particular, to a rechargeable baseball core.

BACKGROUND

Whenever the general public needs sports, ball games are always one of the most important choices. Taking the baseball as an example, it is loved by the general public in both Asia and the United States, and the throwing and catching of baseball is simple and fun, which can achieve both sports and leisure effects. It is particularly suitable for leisure time between brothers, fathers, and friends at home. However, during the day, there is always a period of time for work and study. Therefore, unless it is a holiday, baseball is usually played at night or in the evening. In addition, for teams composed of ordinary amateur players, it is common to practice the ball until night, rendering the baseball with luminous characteristics very important.

At present, a baseball structure with luminous function includes a transparent inner ball and a covering material covering the surface of the inner ball to form a surface structure of the baseball. An outer peripheral surface of the inner ball is provided with a receiving space along a radial direction, and a luminous device is set in the receiving space to emit light from the baseball. The luminous device is penetrated through the receiving space and connected and fixed to the inner ball. The luminous device is equipped with a battery compartment, which is directly electrically connected to the luminous device.

Regarding the relevant technologies mentioned above, a direct electrical connection between the battery and the luminous device can easily lead to self-ignition of the battery. The flame generated by the self-ignition of the battery ignites the luminous device, and finally sprays out from the receiving space to ignite the entire baseball, which can cause greater losses.

DESCRIPTION OF EMBODIMENTS

Further, a detailed explanation of the present application will be provided in combination with FIGS. 1-9.

An embodiment of the present application discloses a rechargeable baseball core. Referring to FIGS. 1 and 2, the rechargeable baseball core includes a luminous ball 1 and a cover 2 covering a surface of the luminous ball 1. Referring to FIG. 3, the luminous ball 1 includes a housing 11, a luminous component 12, and a battery component 13. The housing 11 is a transparent sphere, the luminous component 12 is provided on the housing 11 and configured for luminescent. The battery component 13 is provided on the housing 11. The cover 2 includes two skins 21 and a sewing line 22. The two skins 21 are wrapped around the surface of the luminous ball 1 and form a gap 211. Skins 21 on two sides of the gap 211 are provided with a plurality of sewing holes 212. The sewing line 22 passes through the plurality of sewing holes 212 and sews the gap 211 between the two skins 21. Light emitted by the luminous component 12 passes through the housing 11 and penetrates from the gap 211 between the two skins 21 and each sewing hole 212 to outsides of the skins 21.

The skins 21 used in this embodiment of the present application are the same as a skin 21 used in traditional hard baseball or softball. A distribution path of the sewing holes 212 and the gap 211 provided on the skins 21 follows a distribution path of a red line sewn on the skin 21 of traditional hard baseball or softball. At the same time, a sewing way of the two skins 21 is also the same as that of the skin 21 of traditional hard baseball or softball.

Referring to FIGS. 3 and 4, the housing 11 includes a surface housing 111 and a bottom housing 112. In this embodiment of the present application, a dividing surface between the surface housing 111 and the bottom housing 112 is set as an XY plane 31, which passes through a geometric center of the housing 11. Referring to FIG. 5, a fixed groove 1111 with a circular ring shape is provided on one side of the surface housing 111 close to the bottom housing 112, and a fixed protrusion 1121 with a circular ring shape is fixed on one side of the bottom housing 112 close to the surface housing 111. When the bottom housing 112 and the surface housing 111 are connected, the fixed protrusion 1121 is penetrated through and clamp fixed to the fixed groove 1111. In this embodiment of the present application, a fixing way between the surface housing 111 and the bottom housing 112 uses a hot-pressing connection process, so that the surface housing 111 and the bottom housing 112 are fixed by the hot pressing connection process. Thus, the connection is tight, and a connection area is wide, which renders it difficult for the surface housing 111 and the bottom housing 112 to detach from each other when the housing 11 is subjected by force, thereby ensuring that the luminous component 12 and the battery component 13 remain intact and undamaged when subjected by impact. When the bottom housing 112 and the surface housing 111 are damaged, the luminous component 12 and the battery component 13 continue to be locked and fixed, ensuring the ability of the luminous component 12 and the battery component 13 to continue to use. At the same time, the use process is tool free for snap installation, which does not require any tools to fix the surface housing 111 and the bottom housing 112. Once the surface housing 111 and the bottom housing 112 are pressed together, the surface housing 111 is automatically engaged with the ground, rendering an assembly of the ball core faster and more convenient. This renders the housing 11 less likely to twist during use, ensuring the stability of the flight and operation of the baseball, and thus rendering a flight rotation of the baseball more stable.

Referring to FIGS. 4 and 5, three reinforcing ribs 113 are fixedly provided in the housing 11. A center of gravity of one reinforcing ribs 113 is coincided with a geometric center of the housing 11 and is perpendicular to the XY plane 31. In this embodiment of the present application, a center plane of the reinforcing rib 113 is set as a XZ plane 32, and a plane that is perpendicular to the XZ plane 32 and the XY plane 31 is set as a YZ plane 33. The other two reinforcing ribs 113 have their center planes parallel to the YZ plane 33 and are symmetrically distributed along the YZ plane 33.

Referring to FIGS. 4 and 6, the reinforcing rib 113 includes a first reinforcing portion 1131 and a second reinforcing portion 1132. The first reinforcing portion 1131 is provided on the surface housing 111, and the second reinforcing portion 1132 is provided on the bottom housing 112. The first reinforcing protrusion 11311 is fixedly provided on one side of the first reinforcing portion 1131 close to the second reinforcing portion 1132. The first reinforcing protrusion 11311 is a circular cone with a gradually decreasing diameter size from near the first reinforcing portion 1131 towards near the second reinforcing portion 1132. A reinforcing recess 11321 is provided on one side of the second reinforcing portion 1132 close to the first reinforcing portion 1131. When the surface housing 111 is connected to the bottom housing 112, the first reinforcing protrusion 11311 is penetrated through the reinforcing recess 11321.

Thus, a connection position between the first reinforcing portion 1131 and the second reinforcing portion 1132 still plays an excellent structural strengthening role. At the same time, the providing of the reinforcing rib 113 greatly improves the strength of the housing 11, so that when the luminous ball 1 is impacted, the reinforcing rib 113 will share the pressure subjected by the surface housing 111 and the bottom housing 112, thereby providing additional structural strength for the surface housing 111 and the bottom housing 112, effectively preventing the housing 11 from disassembling under pressure, thus more stably and effectively protecting the luminous component 12 in the housing 11, avoiding damage to the luminous component 12 caused by collision or impact, and an internal space of the housing 11 is tightly matched. At the same time, the surface housing 111 and the bottom housing 112 are thicker, and a plurality of reinforcing ribs 113 are added therein to achieve an effect that the product will not crack, and outside and the internal parts will not be easily damaged when subjected to force, this improvement greatly enhances the durability and endurance of the battery component 13, rendering it better suited for high-intensity sport demands, thereby extending the lifespan of baseball.

Referring to FIGS. 1 and 7, the luminous component 12 includes a first luminous plate 121 located on one side of the surface housing 111.

The charging protection part 1242 closes the charging port 1114. The weights of the rubber protection block 124, the on-off switch 122, and the charging module 123 are symmetrical along the XZ plane 32.

At the same time, the providing of the rubber protection block 124 enables the opening or closing of the luminous component 12 to be controlled externally by directly pressing the switch protection part 1241 outside the luminous ball 1.

Referring to FIGS. 1 and 7, the luminous component 12 further includes a second luminous plate 125, which is located on one side of the bottom housing 112.

The centers of gravity of the battery shell 131 and the battery module 132 are biased towards one side of the bottom housing 112.

In this embodiment of the present application, the first luminous plate 121 and the second luminous plate 125 use high-efficiency light sources, and the battery module 132 uses a 650 mhA battery configuration, which extends the luminous time of the luminous ball 1 and ensures that the luminous effect of the luminous ball 1 remains significantly stable even after long-term use, thereby effectively ensuring the stability and durability of the luminous effect and meeting the needs of long-term movement in nighttime or low light environments.

Referring to FIGS. 8 and 9, the battery shell 131 includes a first shell part 1313 and a second shell part 1314. The first shell part 1313 and the second shell part 1314 are connected. The first shell part 1313 is located on one side of the surface housing 111, and the second shell part 1314 is located on one side of the bottom housing 112. One side of the first shell part 1313 far away from the second shell part 1314 abuts against the first luminous plate 121, and one side of the second shell part 1314 far away from the first shell part 1313 abuts against the second luminous plate 125.

The geometric center of the luminous ball 1 avoids a problem of center of gravity shift caused by additional structures, and a large number of uniform distribution methods are adopted to render the weight distribution of the entire baseball balanced, ensure that the baseball maintains a stable trajectory during throwing and spinning, effectively preventing shaking or irregular rotation during high-speed throwing, rendering a flight path of the baseball easier to predict, and balancing the weight renders it easier for the user to control or grip the baseball.

An implementation principle of the rechargeable baseball core in the present application is as follows: when the battery module 132 self-ignites due to being hit or vibrating, flame generated by the self-ignition of the battery module 132 is isolated by the battery shell 131 due to its fireproof characteristics, rendering it difficult for the flame generated by the self-ignition of the battery module 132 to ignite the battery shell 131 and continue to spread, thereby achieving a goal of preventing flame spread. This improves a direct electrical connection between the battery and the luminous device, which can easily cause the flame generated by the self-ignition of the battery to ignite the luminous device when the battery self-ignites, and finally spray out from a receiving space to ignite the entire baseball, which can easily cause greater losses. At the same time, when the temperature in the battery chamber is too high, it is easy to melt the wires that are electrical connecting the battery module 132 and the luminous component 12. Thereby achieving automatic power-off protection for overheating of the battery component 13.

The above are preferred embodiments of the present application and do not limit the protection scope of the present application.
