DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1 to 7 illustrate the specific structure of the first embodiment of the present invention.
A luminous basketball backboard comprises a light guide backboard 10 and a basketball rim 20 disposed on the front side of the light guide backboard 10. The light guide backboard 10 is provided with an LED light 11 for emitting light toward the light guide backboard 10. The LED light 11 is installed on the top of the light guide backboard 10. The front face or the rear face of the light guide backboard 10 has a plane area 19 and a pattern area 18. The pattern area 18 has a plurality of recesses 12. The pattern area 18 and the plane area 19 are in different planes. When the LED light 11 emits light, the pattern area 18 of the light guide backboard 10 changes the light propagation route so that the pattern area 18 has a darker light color than that of the plane area 19, thereby presenting a corresponding decorative effect, such as patterns, characters, and logos.
In this embodiment, the recesses 12 are formed by laser engraving, injection molding, sticker etching, mesh etching or wire drawing. Preferably, the material of the light guide backboard 10 is glass, acrylic, POM (Polyoxymethylene) or PC (Polycarbonate).
A digital counter 13 is installed to the rear side of the light guide backboard 10. The digital counter 13 is located on the rear side of the light guide backboard 10, which plays a role in protecting the digital counter 13. The digital counter 13 includes a display screen 131 and an induction counting unit 132. The display screen 131 is located on the rear side of the light guide backboard 10 and configured to display digits on the front side of the light guide backboard 10 through the light guide backboard 10. The induction counting unit 132 is located below the basketball rim 20. The light guide backboard 10 has a through hole 15. The induction counting unit 132 is exposed in the through hole 15.
The basketball rim 20 is locked to the front side of the light guide backboard 10 through a mounting frame 21. The mounting frame 21 has a first connecting hole 211. The light guide backboard 10 has a second connecting hole 101. The digital counter 13 has a third connecting hole 133. A first screw 14 is inserted through the first connecting hole 211, the second connecting hole 101 and the third connecting hole 133 in sequence, and the rear end of the first screw 14 is locked with a first nut 141, so that the mounting frame 21 and the digital counter 13 are locked to the light guide backboard 10. It is easy for production and assembly.
The mounting frame 21 includes a first horizontal plate 212 and a vertical plate 213 connected to the rear end of the first horizontal plate 212. The first connecting hole 211 is defined in the vertical plate 213. The upper end of the vertical plate 213 is formed with a first hinge hole 214 extending laterally. The first horizontal plate 212 has a fourth connecting hole 215.
The basketball rim 20 includes a rim body 201 and a second horizontal plate 202 connected to the rear end of the rim body 201. The rear end of the second horizontal plate 202 is formed with a second hinge hole 203 extending laterally. A hinge shaft 204 is inserted through the first hinge hole 214 and the second hinge hole 203, so that the second horizontal plate 202 is hingedly connected to the vertical plate 213.
The second horizontal plate 202 has a fifth connecting hole 205. A second screw 206 is inserted through the fifth connecting hole 205 and the fourth connecting hole 215 in sequence, and the lower end of the second screw 206 is locked with a second nut 207. A spring 208 is sleeved on the second screw 206. The upper and lower ends of the spring 208 act on the second horizontal plate 202 and the first horizontal plate 212, respectively. Through the arrangement of the mounting frame 21, the second horizontal plate 202, the second screw 206, the second nut 207 and the spring 208, the buffering installation connection between the basketball rim 20 and the mounting frame 21 is realized. When a basketball hits the basketball rim 20, the basketball rim 20 will flutter relative to the mounting frame 21 to reduce the impact force generated by the basketball rim 20 on the mounting frame 21, such that the connection between the basketball rim 20 and the mounting frame 21 won't be damaged easily.
The rear side of the light guide backboard 10 is provided with a hook 16. In this embodiment, the rear side of the light guide backboard 10 is provided with two hooks 16. The hook 16 has a mounting portion. The mounting portion has a sixth connecting hole. A third screw is inserted through the sixth connecting hole for locking the hook 16 to the light guide backboard 10. The end of the hook 16 is bent outward to form a guide portion, so that the hook 16 can be installed to a door or wall quickly.
A buffer layer 17 (such as EVA) is attached to the rear side of the light guide backboard 10. The rear end face of the buffer layer 17 is located behind the rear end face of the digital counter 13, or, the rear end face of the buffer layer 17 is flush with the rear end face of the digital counter 13. Through the arrangement of the buffer layer 17, the digital counter 13 is protected well.
FIG. 8 and FIG. 9 illustrate the specific structure of the second embodiment of the present invention. The second embodiment is substantially similar to the first embodiment with the exceptions described hereinafter.
The front face or the rear face of the light guide backboard 10 has a plane area 19 and a pattern area 18. The pattern area 18 is provided with a convex portion 181. The convex portion 181 is integrally formed with the light guide backboard 10.
FIG. 10 illustrates the specific structure of the third embodiment of the present invention. The third embodiment is substantially similar to the first embodiment with the exceptions described hereinafter.
A light guide guard plate 30 is disposed outside of the side where the pattern area 18 of the light guide backboard 10 is located, so that the pattern area 18 is located on the side where the light guide backboard 10 is attached to the light guide guard plate 30. Specifically, in the third embodiment, the pattern area 18 is concavely disposed on the plane area 19. The pattern area 18 is located on the front face of the light guide backboard 10. The light guide guard plate 30 is located on the front side of the light guide backboard 10 and completely covers the front face of the light guide backboard 10.
FIG. 11 illustrates the specific structure of the fourth embodiment of the present invention. The fourth embodiment is substantially similar to the third embodiment, and the main difference is that the pattern area 18 is convexly disposed on the plane area 19.
When the pattern area 18 is disposed on the rear face of the light guide backboard 10, the light guide guard plate 30 is disposed on the rear side of the light guide backboard 10, so that the pattern area 18 is located on the side where the light guide backboard 10 is attached to the light guide guard plate 30 and the light guide guard plate 30 completely covers the rear face of the light guide backboard 10.
The feature of the present invention is that the front face or the rear face of the light guide backboard is provided with the plane area and the pattern area. When the LED light emits light, the pattern area of the light guide backboard changes the light propagation route so that the pattern area has a darker light color than that of the plane area, thereby presenting a corresponding decorative effect, such as patterns, characters, and logos. This solves the problem that the light effect of the entire basketball backboard of the prior art is the same and that the visual effect is not good.
Furthermore, through the arrangement of the mounting frame, the second horizontal plate, the second screw, the second nut and the spring, the buffering installation connection between the basketball rim and the mounting frame is realized. When a basketball hits the basketball rim, the basketball rim will flutter relative to the mounting frame to reduce the impact force generated by the basketball rim on the mounting frame, such that the connection between the basketball rim and the mounting frame won't be damaged easily, and the connection between the mounting frame and the light guide backboard is less susceptible to damage.
In addition, the mounting frame and the digital counter are locked to the light guide backboard, so that the installation structure is simple. It is easy for production and assembly. Besides, the digital counter is located on the rear side of the light guide backboard, which plays a role in protecting the digital counter.
