[0024] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a basketball shooting machine 1000 according to one embodiment of the present invention. The present invention provides a basketball shooting machine 1000, which includes a frame 400, a backboard 200, a basket 300, a controller (not shown), and a goal-sensing device 100. The backboard 200 is mounted on the frame 400, and both the basket 300 and the goal-sensing device 100 are disposed on the backboard 200. The goal-sensing device 100 is located on the bottom side of the basket 300. The controller is electrically connected to the goal sensor and an infrared sensor.

[0025] Specifically, in this embodiment, there are two sets of basketball hoops 300 and goal-sensing devices 100. In other embodiments, the number of basketball hoops 300 and goal-sensing devices 100 may also be other, such as one or three sets.

[0026] Specifically, in this embodiment, the frame 400 is used to be placed on a horizontal support surface such as the ground. In other embodiments, the frame 400 can also be set on a vertical support surface such as a wall.

[0027] Specifically, in this embodiment, the basketball shooting machine 1000 also includes a counter (not shown), which is located on the side of the backboard 200 facing away from the basket 300. The backboard 200 is transparent so that the user can see the counter located behind the backboard 200. The counter has a built-in controller, which is electrically connected to the goal sensor 100 to update the count according to the signal from the goal sensor 100.

[0028] By incorporating the goal-scoring sensor 100 provided in this embodiment of the invention into the basketball shooting machine 1000, the goal-scoring sensor 100 can distinguish between balls of different colors, so as to perform differentiated scoring and counting. The basketball shooting machine 1000 has a stronger entertainment value and meets higher-level entertainment needs.

[0029] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a goal-sensing device 100 according to one embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the disassembled structure of the goal-sensing device 100. This embodiment of the invention provides a goal-sensing device 100, which includes a mounting base 60, a goal sensor (not shown), a trigger rod 70, and an infrared sensor (not shown). The mounting base 60 is used to mount on the backboard 200, and the goal sensor is disposed on the mounting base 60. The trigger rod 70 is rotatably connected to the mounting base 60 and can trigger the goal sensor. The infrared sensor is disposed on the trigger rod 70 and is used to emit infrared rays to the ball and receive the infrared rays reflected back from the ball. Both the goal sensor and the infrared sensor are electrically connected to the controller of the shooting machine 1000.

[0030] Specifically, the trigger lever 70 can rotate in the vertical plane relative to the mounting base 60. When the ball passes through the basket 300 and hits the trigger lever 70, it can cause the trigger lever 70 to rotate relative to the mounting base 60. During the rotation of the trigger lever 70, the goal sensor can be triggered, thereby reading the goal signal. The goal sensor is electrically connected to the controller to send the goal signal to the controller.

[0031] Specifically, the infrared sensor can emit infrared rays toward the point of the basket 300 where the ball is going to go. When the ball passes through the basket 300, the infrared sensor can receive the infrared rays reflected back by the ball and send the intensity signal of the infrared rays to the controller.

[0032] Understandably, for example, in a basketball shooting game where different colored balls correspond to different points, a white ball scores one point, and a black ball scores two points. Utilizing the different reflectivities of black and white objects in specific infrared bands—black objects have an average reflectivity of less than 5% in the near-infrared band (800 nm - 2500 nm), while white objects can reach over 80%—when the intensity of the infrared radiation received by the infrared sensor is lower than a preset value, the controller can determine that the ball that went in is black, adding two points to the original count. Conversely, when the intensity of the infrared radiation received by the infrared sensor is higher than the preset value, the controller can determine that the ball that went in is white, adding one point to the original count. Therefore, the presence of the infrared sensor enables the ball-scoring device 100 to meet the hardware requirements of a point-based scoring rule.

[0033] By installing a goal sensor on the mounting base 60, which is electrically connected to the controller, the controller can determine whether a goal has been scored based on the signal from the goal sensor. At the same time, an infrared sensor is installed on the trigger rod 70, which is electrically connected to the controller. The infrared sensor can emit infrared rays towards the ball and receive the infrared rays reflected back from the ball. Utilizing the characteristic that different colored objects have different reflectivities of infrared rays, the controller can determine the color category of the ball that has scored based on the intensity difference between the emitted and reflected infrared rays. Therefore, it can meet the differentiated requirements for scoring and counting of balls of different colors.

[0034] In one embodiment of this implementation, in order to protect the infrared sensor and prevent the ball from damaging the infrared sensor after hitting the ball, the end of the trigger rod 70 away from the mounting base 60 has a mounting chamber 711, and the infrared sensor is located in the mounting chamber 711.

[0035] In one embodiment of this implementation, in order to facilitate the installation of the infrared sensor, the trigger rod 70 includes a rod body and a cover plate 72, and the cover plate 72 and the rod body enclose an installation chamber 711.

[0036] In one embodiment of this implementation, in order to facilitate the exit of emitted infrared rays from the mounting cavity and the return of infrared rays reflected by the sphere to the mounting cavity 711, the cover plate 72 is provided with a plurality of through holes 721 for the passage of infrared rays.

[0037] In one embodiment of this implementation, in order to connect and fix the rod body and the cover plate 72, an installation post 7111 is formed in the installation chamber 711, the cover plate 72 is provided with a connection hole 722, and the trigger rod 70 includes a locking member (not shown), one end of the locking member abuts against the cover plate 72, and the other end passes through the connection hole 722 and cooperates with the installation post 7111.

[0038] Specifically, the locking element is a screw that passes through the connecting hole 722 and engages with the threaded hole on the mounting post 7111.

[0039] In one embodiment of this implementation, in order to improve the connection strength between the rod body and the cover plate 72, there are multiple mounting posts 7111, connecting holes 722 and locking parts, and they are arranged in a one-to-one correspondence.

[0040] In one embodiment of this implementation, in order to achieve the emission and reception of infrared rays, the infrared sensor includes an infrared emitting unit and an infrared receiving unit. The infrared emitting unit is used to emit infrared rays towards the sphere, and the infrared receiving unit is used to receive the infrared rays reflected back by the sphere.

[0041] In one embodiment of this implementation, in order to achieve a rotatable connection between the trigger rod 70 and the mounting base 60, the mounting base 60 is provided with a shaft 601, and the trigger rod 70 is provided with a shaft hole 701 that rotatably engages with the shaft 601.

[0042] Specifically, the mounting base 60 includes a first housing 61 and a second housing 62. A shaft 601 is disposed on the first housing 61. The first housing 61 and the second housing 62 are connected and clamp one end of the trigger rod 70. The goal sensor is disposed within the space enclosed by the first housing 61 and the second housing 62.

[0043] In one embodiment of this implementation, in order to reset the trigger lever 70, the direction in which the trigger lever 70 rotates relative to the mounting base 60 when it is hit by the ball is defined as the first direction. The ball-scoring sensing device 100 includes a reset elastic element (not shown), which connects the mounting base 60 and the trigger lever 70 to apply an elastic force in a second direction opposite to the first direction to the trigger lever 70.

[0044] Specifically, the reset elastic element is constructed as a spring.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
