Boxing ball with counting function and strike counting method

Abstract

A boxing ball adds a first detection sensor and a sliding block to a head-mounted device, and the sliding block is drivingly connected to an elastic rope. When the striking ball is struck and moves forward, the striking ball drives the sliding block forward through the elastic rope, causing the sliding block to displace relative to the internal mechanism of the head-mounted device. At this time, the first detection sensor detects the sliding block. When the sliding block is displaced, the first detection sensor detects a first detection value exceeding a detection threshold, indicating that the striking ball has been effectively struck.

All of the aforementioned applications are incorporated herein by reference in their entireties.TECHNICAL FIELD

[0002] The present application relates to the technical field of sports equipment, and in particular to a boxing ball with a counting function and a strike counting method for a boxing ball.BACKGROUND

[0003] Boxing balls are devices used for boxing training and fitness, typically for improving a user’s reaction speed, coordination, and striking accuracy. To more intuitively display the user’s training performance and experience, existing boxing balls have added a strike counting function. The existing strike counting functions is generally implemented by attaching sensors to the ball to detect its acceleration, as disclosed in Chinese Patent Publication CN111790130B, entitled “Method and System for Catch Recognition in Intelligent Boxing Ball Training Based on Acceleration”. However, although detecting the acceleration of the ball by setting a sensor facilitates obtaining a numerical value, the force and speed of each hit vary among users and between strikes, resulting in different acceleration values. Consequently, a hit may be valid but not counted when the detected acceleration value fails to exceed a predetermined threshold. Conversely, when the ball may be struck too hard, the rebound speed of the ball may be too fast to cause the acceleration to exceed the threshold, leading to repeated counting even though the ball is not actually struck.SUMMARY

[0016] Compared to the related art, the present application has the following beneficial effects. The boxing ball of the present application adds a first detection sensor and a sliding block to the head-mounted device. The sliding block is drivingly connected to an elastic rope. When the boxing ball is struck and moves forward, the elastic rope drives the sliding block forward, causing the sliding block to displace relative to the internal mechanism of the head-mounted device. The first detection sensor then detects the sliding block. After the sliding block is displaced, the first detection sensor detects a first detection value exceeding a detection threshold, indicating that the boxing ball has been effectively struck. When the boxing ball rebounds, a spring resets the sliding block, at which point the first detection sensor detects a first detection value below the detection threshold. Only after the first detection sensor detects a first detection value below the detection threshold and then again exceeds the detection threshold will the number of effective strikes be counted. Otherwise, the number of effective strikes will not be counted. This ensures accurate counting of effective strikes regardless of the striking force applied to the striking ball by the user. Since the counting sensor is not located on the striking ball, it is not affected by impact forces during counting and is less prone to damage, thereby prolonging the service life of the counting sensor.BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following further describes the specific embodiments of the present application in conjunction with the accompanying drawings to make the technical solutions and beneficial effects of the present application clearer and more specific. The following description of the embodiments with reference to the accompanying drawings is illustrative and intended to explain the present application, but is not to be construed as limiting the present application.

[0031] As shown in FIGS. 1 and 7, a boxing ball with a counting function includes a head-mounted device 1, an elastic rope 2, and a striking ball 3. The head-mounted device 1 is connected to the striking ball 3 via the elastic rope 2. The head-mounted device 1 includes a headband 25, a circuit module 4, a sliding channel 5 disposed at the front end of the circuit module 4, a movable sliding block 6, and a spring 7 for resetting the sliding block 6. The spring 7 can be a compression spring, a tension spring, or a torsion spring. The elastic rope 2 is drivingly connected to the sliding block 6 through the sliding channel 5. The elastic rope 2 can be directly connected to the sliding block 6, with the sliding channel 5 serving to guide the sliding movement of the sliding block 6, or it can be connected to the elastic rope 2 through other mechanisms, such as a rotating column 19, with the sliding channel 5 serving to support the rotating column 19. The circuit module 4 includes a control unit and a first detection sensor connected to the control unit. The first detection sensor is configured to detect whether the sliding block 6 is displaced. The control unit is configured to count the number of times the sliding block 6 is displaced. The first detection sensor can be a Hall sensor 17, a photosensitive sensor, a laser ranging sensor, or a touch sensor, and can determine the displacement change of the sliding block 6 by detecting the distance between the sliding block 6 and the circuit module 4. After the user strikes the striking ball 3, the striking ball 3 moves forward and drives the sliding block 6 forward via the elastic rope 2. The first detection value detected by the first detection sensor will undergo a significant change, either from a small value to a large value or from a large value to a small value. When the striking ball 3 rebounds, if it is not striked by the user, it rebounds onto the user’s body or bounces to the side of the user, with the elastic rope 2 entangled with the user. Both of these situations will reduce the speed of the striking ball 3, preventing the striking ball 3 from driving the sliding block 6 forward too much. The detection value of the first detection sensor will not exceed the judgment threshold, which could lead to false judgments, thereby improving accuracy.

[0032] In an embodiment, the circuit module 4 includes a circuit board 8, the control unit and the first detection sensor are arranged on the circuit board 8, and the circuit board 8 is provided with a through hole 9. The first detection sensor is arranged at the through hole 9, the spring 7 is sleeved on the sliding block 6, and the sliding block 6 is provided with protruding blocks 10 on both sides. The protruding blocks 10 are provided between the spring 7 and the circuit board 8, and the sliding block 6 includes a telescopic portion 14. When the spring 7 is reset, the telescopic portion 14 moves into the through hole 9. The protruding blocks 10 are the two ends of the crossbar, the crossbar is detachably provided at the sliding block 6, and the telescopic portion 14 is provided at the crossbar.

[0033] In an embodiment, the first detection sensor is a photosensitive sensor including a transmitting end 15 and a receiving end 16, respectively disposed on either side of the through hole 9. The telescopic portion 14 of the sliding block 6 serves to block the receiving end 16. The transmitting end 15 may be a light emitter, and the receiving end 16 may be a photoresistor. In an embodiment, the first detection sensor is a Hall sensor 17. The telescopic portion 14 of the sliding block 6 away from the elastic rope 2 is provided with a magnetic block 18. When the elastic rope 2 pulls the sliding block 6, the magnetic block 18 moves forward following the telescopic portion 14, approaching the Hall sensor 17. The circuit board 8 may not have the through hole 9. In this case, the first detection sensor and the telescopic portion 14 can be located on the same side of the circuit board 8. When the first detection sensor is a photosensitive sensor, the telescopic portion 14 also serves as a block. When the first detection sensor is a Hall sensor 17, the magnetic block 18 moves away from the Hall sensor 17 when the sliding block 6 moves forward. When the first detection sensor is a laser ranging sensor, it is positioned at the same location as the photosensitive sensor’s transmitting end 15, or it can be vertically provided at the circuit board 8 to detect the distance between the end face of the telescopic portion 14 and the laser ranging sensor. When the first detection sensor is a touch sensor, the touch sensor is vertically provided at the circuit board 8. When the sliding block 6 is stationary, the spring 7 causes the telescopic portion 14 to contact the touch sensor. When the sliding block 6 moves, the telescopic portion 14 moves away from the touch sensor.

[0034] In an embodiment, the boxing ball also includes a second detection sensor for detecting whether the sliding block 6 is displaced. If the second detection sensor is a photosensitive sensor, the first detection sensor is a Hall sensor 17. If the second detection sensor is a Hall sensor 17, the first detection sensor is a photosensitive sensor.

[0035] In an embodiment, the head-mounted device includes a rotating column 19. A placement groove 20 is provided at the front end of the sliding block 6. An annular limit block 21 is provided at one end of the rotating column 19, and a connection hole 22 is provided at the other end of the rotating column 19. The annular limit block 21 is positioned within the placement groove 20, and the connection hole 22 is configured to connect to the elastic rope 2. During the striking process, the striking ball 3 rotates, which in turn drives the elastic rope 2, causing it to twist. The rotating column 19 then rotates, quickly returning the twisted elastic rope 2 to its original position, enhancing the user experience. In an embodiment, the rotating column 19 may be fixed to the sliding block 6, and a component, such as a bearing or a rotating assembly, can be provided at one end of the rotating column 19 connected to the elastic rope 2, and the elastic rope 2 is reset through the bearing and the rotating assembly.

[0036] In an embodiment, the head-mounted device includes a shell 11 and a left semicircular block 12 and a right semicircular block 13 disposed within the shell 11. The left semicircular block 12 and the right semicircular block 13 are combined into a sliding channel 5, and the spring 7 is sleeved on the left semicircular block 12 and the right semicircular block 13. The left semicircular block 12 is integrally formed with the shell 11, and the spring 7 is sleeved on the ring formed by the left semicircular block 12 and the right semicircular block 13. The protruding block 10 is a long strip. When the sliding block 6 moves forward, the protruding block 10 compresses the spring 7. When the striking ball 3 rebounds, the spring 7 pushes the sliding block 6 to reset via the protruding block 10. When the spring 7 is a tension spring, the sliding block 6 does not need to be provided with the protruding block 10. The tension spring is connected to the end of the sliding block 6 away from the elastic rope 2. When the sliding block 6 moves forward, the sliding block 6 pulls the tension spring. When the striking ball 3 rebounds, the tension spring pulls the sliding block 6 to reset. When the spring 7 is a torsion spring, the sliding block 6 can be provided with a groove for placing the torsion arm of the torsion spring. When the sliding block 6 moves forward, the torsion spring accumulates elastic force. When the striking ball 3 rebounds, the torsion spring resets the sliding block 6 through the accumulated elastic force.

[0037] In an embodiment, the shell 11 is provided with a circular hole 23, which is arranged concentrically with the sliding channel 5. A semicircular groove 24 is provided at the front end of the shell 11, with the circular hole 23 located in the center of the semicircular groove 24. When the striking ball 2 deflects during a strike, the rotating column 19 also deflects. The semicircular groove 24 provides space for the rotating column 19 to deflect, allowing the sliding block 6 to effectively move, thereby improving the accuracy of strike counting.

[0038] In an embodiment, the head-mounted device further includes a broadcast module, which is used to broadcast the number of times the striking ball is struck and change the voice used for the broadcast according to the number of times the striking ball is struck.

[0039] In an embodiment, the striking ball 3 includes a soft sphere, and an inertial sensor, a counting unit, and a light-emitting diode (LED) light are provided in the sphere. The counting unit uses the inertial sensor to record the number of times the striking ball 3 is struck, and changes the color of the LED light accordingly. The striking ball 3 uses the inertial sensor to detect its own acceleration and count the number of strikes, thereby changing its own lighting effects and providing high practicality. The striking ball 3 does not require a wireless connection to the head-mounted device 1, thereby reducing energy consumption and the amount of data to be processed.

[0040] As shown in FIG. 8, a strike counting method for a boxing ball, which is used to count the number of effective strikes of the striking ball of the boxing ball with a counting function, includes the following steps. The head-mounted device 1 obtains a first detection value through a first detection sensor at set intervals, and judges the obtained first detection value. If the first detection value obtained at the current moment is greater than the first set detection value and the first detection value obtained at the previous moment is less than or equal to the first set detection value, the head-mounted device 1 determines that the sliding block 6 is displaced, the striking ball 3 is effectively struck, and the head-mounted device 1 adds 1 to the number of effective strikes of the striking ball 3.

[0041] In an embodiment, at set intervals, the head-mounted device 1 obtains a first detection value through the first detection sensor and simultaneously obtains a second detection value through the second detection sensor. If the head-mounted device 1 determines through the first detection sensor that the sliding block 6 is displaced, the head-mounted device 1 then judges the obtained second detection value. If the second detection value obtained at the current moment is greater than the second set detection value and the second detection value obtained at the previous moment is less than or equal to the second set detection value, the head-mounted device 1 determines that the sliding block 6 is displaced and increases the number of effective strikes of the striking ball 3 by 1. Otherwise, the head-mounted device 1 determines that the sliding block 6 has not displaced and does not increase the number of effective strikes of the striking ball 3. The head-mounted device 1 verifies the detection value of the first detection sensor through the second detection sensor, thereby improving the accuracy of the strike counting by the head-mounted device 1.

[0042] In an embodiment, upon initial operation, the head-mounted device wirelessly connects to an external electronic device. Each time the head-mounted device obtains the number of effective strikes of the striking ball 3, it transmits count information to the external electronic device, allowing the electronic device to count and display the total number of effective strikes of the striking ball of the boxing ball. The head-mounted device wirelessly receives count adjustment commands from the external electronic device to adjust the recorded number of effective strikes of the striking ball. The wireless communication method may be Bluetooth, Wi-Fi, 4G network, or the like. The electronic device may be a mobile phone, tablet, or other electronic device. The head-mounted device may transmit count information to the external electronic device each time it obtains the number of effective strikes of a striking ball, or may transmit the total number of effective strikes of the striking ball to the external electronic device for direct display. When adjusting the number of effective strikes of a striking ball, the external electronic device may not only reset the number of effective strikes of the striking ball of the boxing ball, but also increase or decrease the number of effective strikes of the striking ball, save the current number of effective strikes of the striking ball, and rank the number of effective strikes of the saved striking ball.

[0043] In an embodiment, when the head-mounted device 1 obtains a first detection value greater than a first set detection value, it simultaneously receives an acceleration value obtained by the striking ball 3 via an inertial sensor. The head-mounted device 1 compares the obtained acceleration value with the set acceleration value. If the obtained acceleration value is greater than the set acceleration value, the head-mounted device 1 determines that it is in the ball-striking state and begins counting the number of effective strikes with the striking ball 3 from the time the first detection value greater than the first set detection value is obtained. If the obtained acceleration value is less than or equal to the set acceleration value, the head-mounted device 1 determines that it is not in the ball-striking state and does not count the number of effective strikes with the striking ball 3. The head-mounted device 1 uses the next first detection value greater than the first set detection value as the first detection value greater than the first set detection value. Only when the striking ball 3 is struck does the head-mounted device 1 put the striking ball into the ball-striking state, preventing false detection when the head-mounted device 1 is worn by the user.

[0044] In an embodiment, the broadcast module broadcasts information based on the number of strikes N. When N is 1, the total number of strikes is announced each time the striking ball 3 is struck. When N is 10, the total number of hits is announced only after the striking ball 3 is struck 10 times. The voice of the broadcast module can be changed according to the number of strikes, and the user can also choose the voice to be used for broadcasting. The broadcast voice can be male, female, child, elderly, neutral, or humorous, etc. The broadcast module can also play music, allowing the user to strike the striking ball 3 to the sound of the music.

[0045] The boxing ball described in the present application adds a first detection sensor and a sliding block 6 to the head-mounted device 1. The sliding block 6 is drivingly connected to the elastic rope 2. When the striking ball 3 is struck and moves forward, the striking ball 3 drives the sliding block 6 forward through the elastic rope 2, causing the sliding block 6 to displace relative to the internal mechanism of the head-mounted device 1. The first detection sensor then detects the sliding block 6. After the sliding block 6 has displaced, the first detection sensor detects a first detection value exceeding a detection threshold, indicating that the striking ball 3 has been effectively struck. When the striking ball 3 rebounds, the spring 7 returns the sliding block 6 to its original position, at which point the first detection sensor detects a first detection value below the detection threshold. Only after the first detection sensor detects a first detection value exceeding the detection threshold again after detecting a first detection value below the detection threshold will the number of effective strikes with the striking ball 3 be counted. Otherwise, the number of effective strikes will not be counted. This allows the user to accurately count the number of effective strikes regardless of the force with which the striking ball 3 is struck. The counting sensor is not located on the striking ball 3, so it is not affected by impact forces during counting and is less susceptible to damage, thereby increasing the service life of the counting sensor.
