Description

Technical Field

[0001] This utility model belongs to the field of sports measurement equipment technology, specifically relating to a basketball dribbling and shooting timer. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Basketball dribbling and shooting is a physical education training and examination item for middle school students. Candidates are required to stand at the starting line, start after hearing the instruction, enter the free throw line and shoot five free throws. After successfully shooting the last free throw, they take the ball and dribble to the intersection of the center line and the sideline, return to the designated position and make a layup, then dribble to the same position on the opposite side, return to make a layup and sprint back to the three-point line to end the test.

[0004] Traditional timing methods rely on handheld stopwatches, which are slow. To address this issue, existing technology discloses a timing and scoring system for basketball dribbling and shooting, including a smart host and a goal detector. The goal detector is placed below the basketball hoop to detect whether a shot has been made and sends a goal signal to the smart host. The system also includes an infrared transmitter and receiver at the starting position to detect when the person being tested passes by and sends a detection signal to the smart host to start timing; and a round-trip position detection rod to detect whether the person being tested has reached the designated round-trip position.

[0005] While the above solution addresses the inefficiency of traditional manual timekeeping, the following issues remain: In the above scheme, the shot detector is placed under the basketball hoop and scores when the basketball passes through it. However, after a shot, the basketball may spin inside the hoop and then bounce out, resulting in part of the basketball entering the hoop and the shot detector misscoring. Alternatively, a cheater may throw another ball (the ball should not spin around the hoop and bounce out) and have it pass through the shot detector for scoring. Or, a cheater with cheating intent may throw the basketball directly upwards from under the basket, causing it to pass through the shot detector from bottom to top and score, allowing the cheater to exploit the loophole to cheat. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a basketball dribbling and shooting timer device that can solve the technical problems of existing technology, which only installs a goal detector on the lower side of the basket, resulting in misscoring and easy exploitation of loopholes for cheating.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A basketball dribbling and shooting timing device includes an integrated sensing net mounted on the backboard, an infrared emitting rod placed inside the starting line, and an infrared receiving rod. The integrated sensor net includes a metal net, on which a rim buckle and a scoring buckle are connected. The rim buckle is connected to the top of the metal net along the axis of the metal net, and the scoring buckle is located at a set distance below the rim buckle. At least three infrared sensors are installed on the inside of the rim buckle or the shot buckle. The three infrared sensors are arranged in a circumferential array relative to the center of the rim buckle or the shot buckle, forming two detection units. The three infrared sensors of the rim dunk or the scoring dunk have the same sensing distance and a maximum sensing distance L; when the basketball is in close contact with the inside of the rim dunk or the scoring dunk, the maximum gap between the basketball and the rim dunk or the scoring dunk is the maximum sensing distance L of the infrared sensors.

[0008] Preferably, the maximum sensing distance of the infrared sensor on the rim buckle is greater than the maximum sensing distance of the infrared sensor on the goal buckle.

[0009] Preferably, it also includes a data converter, with the infrared sensor of each detection unit connected individually to the data converter.

[0010] Preferably, the infrared transmitter and receiver are also connected to the data converter.

[0011] Preferably, the data converter is connected to the test host.

[0012] Preferably, the test host is also connected to a display screen and a printer.

[0013] Preferably, the infrared transmitting rod and the infrared receiving rod are mounted opposite each other on the I-shaped base.

[0014] Preferably, the I-shaped base includes a card slot, with a card slot having a center groove. The shape and size of the card slot are consistent with the bottom shape and size of the infrared emitting rod or infrared receiving rod.

[0015] Preferably, anti-tipping blocks are integrally connected to both sides of the card holder, and anti-tipping protrusions are integrally connected to both ends of the anti-tipping blocks.

[0016] Preferably, the I-shaped base is placed on the side of the starting line close to the backboard, and the anti-tipping block of the I-shaped base is parallel to the starting line, so that the edge of the outer anti-tipping block coincides with the starting line.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: This utility model's integrated sensor-controlled basketball net features multiple infrared sensors installed on both the hoop rim buckle and the shot buckle, forming two detection units. Points are only awarded when the basketball enters the hoop and passes through both detection units from top to bottom, preventing misscoring and preventing cheaters from throwing the ball upwards to gain points, thus ensuring fairness. Furthermore, the multiple infrared sensors are arranged in a circumferential array, each with a maximum detection distance. Points are only awarded when all multiple infrared sensors detect the basketball passing through, preventing cheaters from throwing small balls to gain points, further ensuring fairness.

Detailed Implementation

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] Definitions: Infrared sensor: A sensor that uses the physical properties of infrared light to perform measurements.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a basketball dribbling and shooting timer device, such as... Figure 1 As shown, the system includes an integrated sensor net 4 mounted on the backboard 3, which senses whether the basketball has entered the basket and completed a scoring action; it also includes an infrared transmitter 1 and an infrared receiver 2 placed inside the starting line 7 outside the three-point line. When the person being tested passes between the infrared transmitter 1 and the infrared receiver 2, the timing can be triggered or stopped. It should be noted that the timing is triggered when the person being tested passes between the infrared transmitter 1 and the infrared receiver 2 for the first time, and the timing is stopped when the person being tested passes between the infrared transmitter 1 and the infrared receiver 2 for the second time after completing the free throw, dribbling, and layup actions.

[0023] like Figure 2 As shown, the integrated sensor-guided basketball net 4 includes a metal net 41, with a rim buckle 42 and a shot buckle 43 connected to the metal net 41. The rim buckle 42 is connected to the top of the metal net 41, and the shot buckle 43 is located at a predetermined distance below the rim buckle 42 along the axial direction of the metal net 41. In this embodiment, the shot buckle 43 is located 15 to 20 centimeters below the rim buckle 42.

[0024] like Figure 2 As shown, multiple infrared sensors 44 are installed on the inner side of both the rim buckle 42 and the goal buckle 43. The multiple infrared sensors 44 are evenly installed on the inner side of the rim buckle 42 or the goal buckle 43. The multiple infrared sensors 44 are arranged in a circumferential array relative to the center of the rim buckle 42 or the goal buckle 43 to form two detection units, which can detect whether the basketball has been successfully scored.

[0025] It should be noted that the rim buckle 42 or the shot buckle 43 can be made of metal. When connecting the rim buckle 42 or the shot buckle 43 to the metal net 41, welding or nylon cable ties can be used. When connecting the integrated sensor net 4 to the existing rim, nylon cable ties can also be used, with the ends of the cable ties facing outwards to avoid interfering with shooting. The infrared sensor 44 can be glued to the inside of the rim buckle 42 or the shot buckle 43.

[0026] Specifically, if the infrared sensor 44 (the upper detection unit) of the hoop rim buckle 42 detects the basketball entering the hoop, but the infrared sensor 44 (the lower detection unit) of the scoring buckle 43 does not detect the basketball entering the hoop, then the basketball is deemed not to have scored. If the scoring buckle 43 detects a goal, but the hoop rim buckle 42 does not, or if the scoring buckle 43 detects a goal first, and the hoop rim buckle 42 detects a goal later, then the goal is deemed invalid, indicating suspected cheating. If the infrared sensor 44 of the hoop rim buckle 42 detects the basketball entering the hoop first, and the infrared sensor 44 of the scoring buckle 43 detects the basketball entering the hoop later, then the basketball is deemed to have scored validly.

[0027] Understandably, the integrated sensor-controlled basketball net 4 uses a rim buckle 42 and a shot buckle 43, with multiple infrared sensors 44 installed inside both rim buckles 42 and shot buckles 43, forming two detection units to detect whether a shot has been successfully made. When a shot occurs where the basketball spins inside the rim but bounces out, only the infrared sensor 44 on the rim buckle 42 can detect the portion of the ball entering the rim, but the infrared sensor 44 on the shot buckle 43 cannot detect it, so no points are scored. This solves the problem of misscoring when using shot detectors at the rim in existing technologies. Furthermore, if an intentional cheater throws the ball directly upwards from under the basket, causing it to pass through the rim buckle 42 and shot buckle 43 from below, no points are scored because the shot is made in the wrong order. This solves the technical problem in existing technologies where shot detectors at the rim allow cheaters to exploit loopholes by throwing the ball upwards.

[0028] It should also be noted that, in the embodiments, such as Figure 2 , Figure 3 As shown, at least three infrared sensors 44 are evenly installed on the inner side of the rim buckle 42 or the goal buckle 43, and the three infrared sensors 44 are arranged in a circumferential array relative to the center of the rim buckle 42 or the goal buckle 43.

[0029] In this embodiment, the three infrared sensors 44 of the rim buckle 42 or the scoring buckle 43 have the same sensing distance and a maximum sensing distance L. For example... Figure 3 As shown, when the basketball is in close contact with the inside of the rim buckle 42 or the scoring buckle 43, the maximum gap between the basketball and the rim buckle 42 or the scoring buckle 43 is the maximum sensing distance L of the infrared sensor 44.

[0030] It is understandable that the maximum sensing distance of the infrared sensor 44 on the rim dunk ring 42 is different from the maximum sensing distance of the infrared sensor 44 on the scoring dunk ring 43; the maximum sensing distance of the infrared sensor 44 on the rim dunk ring 42 is greater than the maximum sensing distance of the infrared sensor 44 on the scoring dunk ring 43.

[0031] It needs to be explained that the infrared sensors 44 on the rim swivel ring 42 or the scoring ring 43 are set with a maximum sensing distance, enabling the basketball to be detected simultaneously by all three infrared sensors 44 when it passes the rim swivel ring 42 or the scoring ring 43. While the small ball is also spherical, its diameter is smaller, and when it passes the rim, the maximum sensing distance of the three infrared sensors 44 is limited, meaning the small ball cannot be detected simultaneously by all three sensors 44. This solves the technical problem in existing technologies where a scoring detector is placed at the rim, allowing cheaters to throw a small ball and exploit a loophole to cheat.

[0032] like Figure 1 As shown, a basketball dribbling and shooting timer device also includes a data converter 6. The two detection units of the integrated sensing net 4 are connected to the data converter 6 via data connection cables 5. The infrared emitting rod 1 and the infrared receiving rod 2 are also connected to the data converter 6 via data connection cables 5. The data converter 6 is connected to the test host 8 via data connection cables 5, transmitting the detection data from the integrated sensing net 4, infrared emitting rod 1, and infrared receiving rod 2 to the test host 8 for recording the score, start time, and end time of the shot taken by the tested player. In this embodiment, the data converter 6 can be a protocol chip.

[0033] Specifically, the input end of the data converter 6 is connected to the infrared emitting rod 1, the infrared receiving rod 2, and the integrated sensing net 4 via the data connection cable 5, respectively, for receiving and processing the sensing signals; the output end of the data converter 6 is connected to the test host 8 via the data connection cable 5, and the test host 8 is used to record the results (goal score and test time). In summary, the number of goals scored by the tested personnel and the test time are both recorded by the test host 8.

[0034] like Figure 1 As shown, the test host 8 is also connected to a display screen 9 and a printer 10. In this embodiment, the test host 8 is a computer as in the prior art, and the display screen 9 is an LED display screen. The test host 8 displays the basic information of the test taker, reads the score data through software and records it into the examination database, and displays the current test taker's score on the display screen 9, allowing the test taker to see their score intuitively on-site, ensuring the fairness, impartiality and openness of the examination; the test host 8 is connected to the printer 10, which can directly print the current test taker's score for the test taker to confirm the score on-site.

[0035] like Figure 4 As shown, infrared emitting rod 1 and infrared receiving rod 2 are movably mounted on the I-shaped base 21, which supports either infrared emitting rod 1 or infrared receiving rod 2. It should be noted that infrared emitting rod 1 and infrared receiving rod 2 are positioned opposite each other.

[0036] like Figure 4 , Figure 5As shown, the I-shaped base 21 includes a card slot 22, and a card slot 23 is formed in the center of the card slot 22. The shape and size of the card slot 23 are consistent with the shape and size of the bottom end of the infrared emitting rod 1 or the infrared receiving rod 2. The bottom end of the infrared emitting rod 1 or the infrared receiving rod 2 is inserted into the card slot 23 so that the infrared emitting rod 1 or the infrared receiving rod 2 is set perpendicular to the ground.

[0037] like Figure 5 As shown, anti-tipping blocks 24 are integrally connected to both sides of the card holder 22, and anti-tipping protrusions 25 are integrally connected to both ends of the anti-tipping blocks 24. The anti-tipping blocks 24 can prevent the infrared emitting rod 1 or the infrared receiving rod 2 from tipping to both sides of the card holder 22, and the anti-tipping protrusions 25 can prevent the infrared emitting rod 1 or the infrared receiving rod 2 from tipping to both ends of the card holder 22.

[0038] It is important to note that, such as Figure 1 As shown, the I-shaped base 21 is placed on the side of the starting line 7 near the backboard 3, so that the anti-tipping block 24 of the I-shaped base 21 is parallel to the starting line 7, and the edge of the outer anti-tipping block 24 coincides with the starting line 7. The anti-tipping block 24 can serve as a positioning tool, allowing the infrared emitting rod 1 and the infrared receiving rod 2 to be positioned on a straight line, thereby ensuring that the infrared receiving rod 2 can collect the signal from the infrared emitting rod 1.

[0039] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
