The present disclosure relates to the technical field of ball equipment, and in particular, to a luminous ball.
As a widely popular and interesting sport, ball sports have been favored since they emerged. People often engage in ball sports such as basketball, football, and rugby in their spare time. Even in a low light environment such as at night, there are still many ball sports enthusiasts engaging in ball sports.
However, most existing balls on the market are not luminous, so that ball sports enthusiasts have to engage in ball sports in an environment with sufficient lighting, which limits usage scenarios and brings inconvenience to use by people. Some balls will be provided with lamps. Shells of some of these products cannot transmit light, and shells of some other products have poor light transmittance. If weak light is emitted, the products cannot be easily observed in a dark environment. Some lamps emit strong light which may easily directly hit the eyes of the ball sports enthusiasts. This affects the user experience. Moreover, batteries and lamps on some balls cannot be replaced, or it is troublesome to replace the batteries and lamps, and special tools need to be used. Once the batteries are depleted or the lamps are damaged, the entire products cannot be luminous and cannot continue to be used in the low light environment. There are still some products having smooth outer surfaces and low friction force. This product easily falls off from the hands of a user when the user holds the product. In addition, their shells are too hard, so that the hand feel is poor.

an accommodating shell 500, wherein an accommodating slot 501 is provided in the accommodating shell 500; the accommodating shell 500 is connected to a position, close to an edge of the second opening 102, of the light-transmittance inner airbag 100; the accommodating shell 500 is at least partially placed into the inflation space 101;
a light-transmittance outer surface layer 200, wherein the light-transmittance outer surface layer 200 is wrapped around an outer surface of the light-transmittance inner airbag 100; the light-transmittance outer surface layer 200 is provided with a first opening 201; the first opening 201 corresponds to the second opening 102; and the light-transmittance outer surface layer 200 is made of PVC or fabric;
a light-emitting assembly 300, wherein the light-emitting assembly 300 is detachably inserted into the accommodating slot 501; and
a cover body 400, wherein the cover body 400 is in detachable threaded connection to an inner wall of the accommodating slot 501 and covers the accommodating slot 501 to limit the light-emitting assembly 300 in the accommodating slot 501.
By the arrangement of the above structure, during use, the light-emitting assembly 300 is placed in the accommodating slot 501, and the cover body 400 covers the accommodating slot 501. The cover body 400 can effectively limit the light-emitting assembly 300, prevent the light-emitting assembly 300 from shaking, and ensure the structural stability. A side wall of at least a portion of the accommodating slot 501 is transparent. Light generated by the light-emitting assembly 300 passes through the side walls of the accommodating slot 501 and enters the light-transmittance inner airbag 100, and illuminates the light-transmittance inner airbag 100 and the light-transmittance outer surface layer 200, making the product emit soft light. A user can easily observe the ball in a low light condition such as at night, which not only makes the product more beautiful, but also facilitates the user to observe and use the product. Preferably, the light-transmittance inner airbag 100 is made of white transparent PVC and has a rough surface. The light generated by the light-emitting assembly 300 illuminates the light-transmittance inner airbag 100, so that the light-transmittance inner airbag 100 emits soft and uniform light. The soft light passes through a gap on the light-transmittance outer surface layer 200 and illuminates the light-transmittance outer surface layer 200, making it convenient for the user to observe the product. During use, an edge of the accommodating shell 500 is to the light-transmittance inner airbag 100 at the edge of the second opening 102 to achieve sealed connection between the accommodating shell 500 and the light-transmittance inner airbag 100. The accommodating slot 501 is arranged in the accommodating shell 500 to reduce the production difficulty, improve the production efficiency of the product, and increase the yield of the product under the condition of ensuring the airtightness of the product. Moreover, the cover body 400 is in threaded connection to the inner wall of the accommodating slot 501, which can make it convenient for a user to disassemble and assemble the cover body 400, thereby replacing the battery for the light-emitting assembly 300 or replacing the light-emitting assembly 300 and prolonging the battery life and service life of the product. Moreover, the threaded connection can enhance the sealing performance between the cover body 400 and the accommodating slot 501, prevent water from entering the light-emitting assembly, and ensuring the stability of the product. Furthermore, since the light-transmittance outer surface layer 200 is made of the PVC or fabric, the light-transmittance outer surface layer 200 is softer and has a better hand feel, and the user feels more comfortable when holding the product. Meanwhile, antiskid lines are provided on an outer surface of the light-transmittance outer surface layer 200 made of the PVC or fabric, so that the surface friction coefficient is large, which can effectively achieve skid resistance, and the user holds the product more stably. The friction coefficient can be further increased by adding antiskid silica gel patterns, to enhance the antiskid effect. Furthermore, due to good light transmittance, light generated by the light-emitting assembly 300 passes through the light-transmittance outer surface layer 200 more easily, so that the product has higher brightness, which facilitates the user to observe the product under a low light condition.

The light-transmittance inner airbag is reinforced by winding yarn made of a nylon wire or a polyester mixture to maintain its shape stability, and a rubber layer is added to improve the stability and elasticity of the product.
In this embodiment, the light-transmittance outer surface layer 200 is made of polyester fabric or foamed PVC light-transmittance sheet. It is sewn to form the spherical or fusiform light-transmittance outer surface layer 200 and wrapped around the outer surface of the light-transmittance inner airbag 100.
