Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, specifically a light-emitting ball for sports training. Background Technology

[0002] In sports training and recreational activities, ball games are highly favored due to their wide participation and fun. To enhance training effectiveness or improve the recreational experience, ball products with luminous functions have gradually emerged on the market. These products, with built-in light-emitting components, can be used in low-light environments, thus expanding the application scenarios of ball games. However, existing luminous ball products still have many shortcomings in design and practical application, limiting their further promotion and use. Traditional luminous balls typically install the light-emitting component in a separate housing cavity. This structure not only increases the complexity of the product but also raises production and assembly costs. At the same time, the presence of the housing cavity may affect the overall balance of the ball, leading to irregular bouncing or deviations in trajectory during use. In addition, the waterproof performance of existing luminous balls is generally poor, especially in inflatable balls. It is difficult to guarantee the seal between the light-emitting component and the ball, making it prone to leakage or damage due to changes in air pressure or external environmental influences. This not only reduces the product's lifespan but also poses challenges to the stability and safety of the light-emitting component. Utility Model Content

[0003] This invention addresses the problems of complex structure, insufficient waterproof performance, and low assembly efficiency of existing luminous balls used in sports training. It proposes an improved technical solution that directly wraps the luminous component in a waterproof elastic membrane layer and achieves a sealing effect by combining the elastic properties of the ball, thereby avoiding the defect of needing to set up a receiving cavity in the traditional design.

[0004] This invention provides a light-emitting ball for sports training, comprising a ball body, a light-emitting component, and a valve core. The ball body is made of PVC material and has a certain degree of elasticity. The light-emitting component includes a control board, a battery, a charging interface, and a lamp. The control board is equipped with a microswitch for detecting the ball's vibration state and controlling the lamp's on / off state. The valve core and the light-emitting component are located at opposite ends of one diameter of the ball to ensure the ball's balance during use.

[0005] Furthermore, the sphere's wall is provided with a through hole located on the opposite side of the valve core for mounting a charging interface holder. The charging interface holder is a cylindrical structure with threads on its cylindrical surface. One end connects to the control plate, and the other end has a circular locking head. The charging interface of the charging interface holder is located within this circular locking head. The diameter of the circular locking head is larger than the diameter of the through hole to ensure the charging interface holder is securely installed inside the sphere. The charging interface of the charging interface holder faces outwards from the sphere and is equipped with a sealing cover to protect the charging interface and prevent dust and moisture from entering.

[0006] Specifically, except for the charging port of the charging socket, the light-emitting component is covered by a waterproof elastic membrane layer, at least covering the area excluding the light-emitting part of the lamp. If the waterproof elastic membrane layer is a transparent material, the entire light-emitting component (except for the charging port) is covered; if the waterproof elastic membrane layer is a non-transparent material, it only covers the area excluding the light-emitting part of the lamp. The waterproof elastic membrane layer is formed by spraying with an oil-based (solvent-based) fluorinated nano-coating or silicone-modified nanomaterial, with a thickness of at least 0.5 mm. This waterproof elastic membrane layer has good waterproof, anti-permeability, and elastic properties.

[0007] Furthermore, the sealing and fixing principle is achieved through the interference fit between the cylindrical charging interface seat and the through hole. Utilizing the elasticity of the sphere and the flexibility of the waterproof elastic membrane layer, the charging interface seat is subjected to greater compressive force after the sphere is inflated, further enhancing the sealing performance.

[0008] Through the above technical solution, this utility model achieves the following beneficial effects: First, by directly wrapping the light-emitting component in the waterproof elastic membrane layer, the traditional cavity design is eliminated, simplifying the overall structure and reducing production costs. Second, the waterproof elastic membrane layer is sprayed with oil-based nanomaterials, forming a dense, non-porous protective layer with excellent waterproof and anti-permeability properties. Furthermore, the oil-based system has advantages over water-based coatings in terms of fast drying and anti-permeability. Third, the light-emitting component is flexibly fixed to the sphere through the waterproof elastic membrane layer, achieving a sealing effect combined with the sphere's elastic properties, eliminating the need for complex assembly processes and improving product assembly efficiency. In addition, the light-emitting component adopts a rechargeable design, allowing users to charge the battery via the charging interface without disassembly, making it more convenient to use. Finally, the light-emitting component and valve core are positioned opposite each other to ensure the sphere remains balanced during use; the charging interface is equipped with a sealing cover, further enhancing dustproof and waterproof performance and extending service life.

[0015] This utility model provides a light-emitting ball for sports training, as detailed below. Figure 1 To be continued Figure 3 The specific embodiments of this utility model are described in detail below. The sphere 1 described in the embodiments is made of PVC material, possessing a certain degree of elasticity, and is suitable for various sports scenarios, such as rugby, basketball, volleyball, and soccer. The sphere 1 contains a light-emitting component 2 and a valve core 3. The light-emitting component 2 includes a control board 21, a battery 22, a charging interface 23, and a lamp 24. The light-emitting component 2 is sealed by a waterproof elastic membrane layer, utilizing the elastic properties of the sphere 1 to achieve a sealing effect, thereby avoiding the defects of traditional designs that require a receiving cavity.

[0016] In the specific implementation process, a through hole 4 is provided on the wall of the sphere 1, located on the opposite side of the valve core 3, for installing the charging interface seat 23. The through hole 4 is designed as a countersunk hole with the head facing outward, so that the circular locking head 231 and the sealing cover 5 can be completely recessed into the head of the through hole 4, ensuring the flatness of the surface of the sphere 1. The charging interface seat 23 is a cylindrical structure with a diameter larger than that of the through hole 4, and is fixed in the through hole 4 by interference fit. The cylindrical surface of the charging interface seat 23 is threaded, with one end connected to the control plate 21 and the other end provided with a circular locking head 231. The charging interface of the charging interface seat 23 is located in the circular locking head 231. The diameter of the circular locking head 231 is larger than that of the through hole 4, so it can be firmly locked on the outside of the sphere 1 during installation, preventing the charging interface seat 23 from falling off. The charging interface of the charging interface seat 23 faces the outside of the sphere 1 and is equipped with a sealing cover 5 to protect the charging interface and prevent dust and moisture from entering. The sealing cap 5 matches the head shape of the through hole 4, and the surface is flat after installation, which does not affect the overall appearance of the sphere 1.

[0017] The remaining portion of the light-emitting component 2 is encased in a waterproof elastic membrane layer. Except for the charging port of the charging port socket 23, the waterproof elastic membrane layer covers at least the area of ​​the lamp 24 excluding its light-emitting portion. The waterproof elastic membrane layer is formed using a spraying process, with the spraying material being an oil-based fluorine-containing nano-coating or silicone-modified nanomaterials. The nanoparticles in the spraying material form a dense, non-porous protective layer with a thickness of at least 0.5 mm after the solvent evaporates. If the waterproof elastic membrane layer is a non-transparent material, the light-emitting portion of the lamp 24 must be avoided during spraying to ensure that the light-emitting effect is not affected; if the waterproof elastic membrane layer is a transparent material and does not affect light transmission, the entire light-emitting component 2 (excluding the charging port) can be encased within it. After the spraying process is completed, the waterproof elastic membrane layer combines with the elastic properties of the sphere 1. After the sphere 1 is inflated and expanded, the charging port socket 23 experiences greater compressive force, further enhancing the sealing performance.

[0018] The circuit control principle of the light-emitting component 2 is as follows: A microswitch is provided on the control board 21 to detect the vibration state of the sphere 1 and control the on / off state of the lamp 24. When the sphere 1 is vibrated, the microswitch detects the signal and triggers the lamp 24 to light up, making the sphere 1 emit light. The color and brightness of the lamp 24 can be adjusted according to actual needs. For example, a multi-color lighting effect can be achieved by setting different LED beads on the control board 21. If no vibration signal is detected after the sphere 1 is stationary for 60 seconds, the control board 21 automatically turns off the lamp 24 to save energy. In addition, the control board 21 also integrates a charging management module for charging management of the battery 22. Users can charge the battery 22 through the charging interface 23, achieving continuous power supply without disassembling the light-emitting component 2.

[0019] During assembly, the control board 21, battery 22, and lamp 24 of the light-emitting component 2 are first assembled, and one end of the charging interface socket 23 is connected to the control board 21. Then, the assembled light-emitting component 2 is placed inside the sphere 1, and the charging interface socket 23 is inserted into the through hole 4. Since the diameter of the charging interface socket 23 is larger than the diameter of the through hole 4, the elastic properties of the sphere 1 are utilized during installation. Appropriate external force is applied to press the charging interface socket 23 into the through hole 4 until the circular locking head 231 completely locks the outside of the sphere 1. After installation, a waterproof elastic film layer is sprayed onto the surface of the light-emitting component 2 using a spraying device, ensuring that the sprayed material evenly covers the designated area. After spraying, the solvent is allowed to evaporate, forming a dense protective layer. Finally, the sealing cap 5 is installed on the charging interface of the charging interface socket 23, completing the entire assembly process.

[0020] In practical applications, the luminous ball for sports training of this invention provides excellent visual effects in low-light environments, making it suitable for nighttime training or recreational activities. For example, in nighttime soccer training, players can quickly judge the ball's trajectory by observing its position, improving training efficiency. The luminous effect of the ball 1 can be automatically controlled by a microswitch on the control board 21, automatically turning off the light 24 after the ball 1 has been stationary for 60 seconds, avoiding unnecessary energy consumption. Furthermore, the design of the charging port 23 allows users to charge the battery 22 without disassembling the luminous component 2, simplifying the maintenance process. The sealing cover 5 further enhances the product's dustproof and waterproof performance, extending its service life.

[0021] In summary, this invention eliminates the need for traditional cavity designs by directly encasing the light-emitting component 2 within a waterproof elastic membrane layer, simplifying the overall structure and reducing production costs. The waterproof elastic membrane layer is sprayed with oil-based nanomaterials, forming a dense, non-porous protective layer with excellent waterproof and anti-permeability properties. Furthermore, the oil-based system offers advantages over water-based coatings in terms of fast drying and anti-permeability. The light-emitting component 2 is flexibly fixed to the sphere 1 via the waterproof elastic membrane layer, achieving a sealing effect through the elastic properties of the sphere 1, eliminating the need for complex assembly processes and improving product assembly efficiency. In addition, the light-emitting component 2 features a rechargeable design, allowing users to charge the battery 22 via the charging interface 23 without disassembly, making it more convenient to use. The light-emitting component 2 is positioned opposite the valve core 3 to ensure the sphere 1 remains balanced during use; the charging interface 23 is equipped with a sealing cover 5, further enhancing dustproof and waterproof performance and extending service life. This invention provides a simple, low-cost, highly efficient, and waterproof luminous ball for sports training, suitable for various sports scenarios, and possessing high practical value and market potential.
