The circuit module 4 includes a control unit and a first detection sensor connected to the control unit. The first detection sensor is used to detect whether the sliding block 6 is displaced. The control unit is used 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 distance sensor or a touch sensor, etc. The displacement change of the sliding block 6 can be determined by detecting the distance between the sliding block 6 and the circuit module 4. After the user hits the striking ball 3, the striking ball 3 moves forward and drives the sliding block 6 to slide forward through the elastic rope 2. The first detection value detected by the first detection sensor will have a large change process, which can be 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 hit by the user, the striking ball 3 rebounds to the user's body, or bounces to the side of the user, and the elastic rope 2 is wrapped around the user. Both of these situations will reduce the speed of the striking ball 3, so that the striking ball 3 will not drive the sliding block 6 to move forward too much, and the detection value of the first detection sensor will not exceed the judgment threshold, and there will be a misjudgment, and the accuracy rate is high.

[0030] As one 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, 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, the two sides of the sliding block 6 are provided with protrusions 10, the protrusions 10 are located between the spring 7 and the circuit board 8, the sliding block 6 includes a telescopic part 14, when the spring 7 is reset, the telescopic part 14 is moved into the through hole 9. The protrusions 10 are the two ends of the cross bar, the cross bar is detachably arranged on the sliding block 6, and the telescopic part 14 is arranged on the cross bar.

[0031] As one embodiment, the first detection sensor is a photosensitive sensor, and the photosensitive sensor includes a transmitting end 15 and a receiving end 16, and the transmitting end 15 and the receiving end 16 are respectively arranged on both sides of the through hole 9, and the telescopic part 14 of the sliding block 6 plays a role of blocking the receiving end 16, and the transmitting end 15 can be a transmitter that emits light, and the receiving end 16 can be a photoresistor. Alternatively, the first detection sensor is a Hall sensor 17, and the telescopic part 14 of the sliding block 6 at one end away from the elastic rope 2 is provided with a magnetic block 18, and when the elastic rope 2 pulls the sliding block 6, the magnetic block 18 moves forward according to the telescopic part 14 and approaches the Hall sensor 17. The circuit board 8 may not be provided with a through hole 9, and in this case, the first detection sensor and the telescopic part 14 can be located on the same side of the circuit board 8. When the first detection sensor is a photosensitive sensor, the telescopic part 14 also plays a blocking role. When the first detection sensor is a Hall sensor 17, when the sliding block 6 moves forward, the magnetic block 18 is away from the Hall sensor 17. When the first detection sensor is a laser distance sensor, the laser distance sensor is set at the same position as the transmitting end 15 of the photosensitive sensor, or can be set vertically on the circuit board 8 to detect the distance between the end face of the telescopic part 14 and the laser distance sensor. When the first detection sensor is a touch sensor, the touch sensor is vertically set on the circuit board 8. When the sliding block 6 does not move, the spring 7 makes the telescopic part 14 contact the touch sensor. When the sliding block 6 moves, the telescopic part 14 will leave the touch sensor.

[0032] As one embodiment, the fighting ball also includes a second detection sensor for detecting whether the sliding block 6 sends a displacement; 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.

[0033] As one embodiment, the head-mounted device includes a rotating column 19, a placement slot 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 connecting hole 22 is provided at the other end, the annular limit block 21 is provided in the placement slot 20, and the connecting hole 22 is used to connect with the elastic cord 2, and the elastic cord 2 can be adjusted in length by untying and then retyping the elastic cord 2 at the connecting hole 22. The striking ball 3 will rotate during the striking process, and the striking ball 3 will drive the elastic cord 2 to rotate during the rotation process, so that the elastic cord 2 is in a twisted state, and the rotating column 19 rotates, so that the twisted elastic cord 2 quickly returns to its original position, thereby increasing the user experience. Alternatively, the rotating column 19 is fixedly arranged with the sliding block 6, and a component such as a bearing, a rotating kit, etc. can be rotated at one end of the rotating column 19 connected to the elastic cord 2, and the elastic cord 2 is reset through the bearing and the rotating kit.

[0034] As one embodiment, the head-mounted device includes a housing 11 and a left semicircular block 12 and a right semicircular block 13 arranged in the housing 11, the left semicircular block 12 and the right semicircular block 13 are combined to form 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 integrated with the housing 11, the spring 7 is sleeved on the ring formed by the left semicircular block 12 and the right semicircular block 13, the protrusion 10 is in the shape of a long strip, when the sliding block 6 moves forward, the protrusion 10 will compress the spring 7, when the striking ball 3 rebounds, the spring 7 pushes the sliding block 6 to reset through the protrusion 10. When the spring 7 is a tension spring, the sliding block 6 does not need to be provided with the protrusion 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.

[0035] As one embodiment, the housing 11 is provided with a circular hole 23, the circular hole 23 is co-centered with the sliding channel 5, the front end of the housing 11 is provided with a semicircular groove 24, and the circular hole 23 is located in the middle of the semicircular groove 24. When the striking ball 2 is offset during the striking process, the rotating column 19 will also be offset. At this time, the semicircular groove 24 provides a space for the rotating column 19 to offset, so that the sliding block 6 can also be effectively displaced, thereby improving the accuracy of the shot counting.

[0036] As one embodiment, the head mounted device further includes a broadcast module, and the broadcast module is used to broadcast the number of times the batting ball is hit, and to change the voice used for the broadcast according to the number of times the batting ball is hit.

[0037] As one embodiment, the striking ball 3 includes a sphere made of soft material and an inertial sensor, a counting unit and an LED light arranged in the sphere. The counting unit records the number of times the striking ball 3 is struck through the inertial sensor and changes the light color of the LED light according to the number of times it is struck. The striking ball 3 detects its own acceleration through the inertial sensor to count the number of strikes, thereby changing its own lighting effect. It is highly practical. The striking ball 3 does not need to be wirelessly connected to the head-mounted device 1, which reduces energy consumption and reduces the data that needs to be processed.

[0038] like Figure 8As shown, a method for counting the shots of a fighting ball is used to count the effective number of shots of the fighting ball with a counting function, and the method includes the following steps: the head mounted device 1 obtains a first detection value through a first detection sensor at every set time, 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 effective number of shots of the striking ball 3.

[0039] As one embodiment, it is characterized in that when the head mounted device 1 obtains the first detection value through the first detection sensor at every set time, it obtains the second detection value through the second detection sensor at the same time; if the head mounted device 1 determines that the sliding block 6 is displaced through the first detection sensor, the head mounted device 1 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 adds 1 to the effective number of hits of the striking ball 3; otherwise, the head mounted device 1 determines that the sliding block 6 is not displaced, and does not increase the effective number of hits 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 hitting count of the head mounted device 1.

[0040] As one embodiment, when the head-mounted device starts working, it is first connected to an external electronic device by wireless means; each time the head-mounted device obtains the effective number of hits of a batting ball, it will send a counting information to the external electronic device, so that the electronic device can count and display the total effective number of hits of the batting ball; the head-mounted device receives the counting adjustment command sent by the external electronic device by wireless means to adjust the recorded effective number of hits of the batting ball. The wireless method can be Bluetooth, Wi-Fi, 4G network, etc. The electronic device can be an electronic device such as a mobile phone or a tablet. The head-mounted device can send a counting information to the external electronic device each time it obtains the effective number of hits of a batting ball, and can also send the total effective number of hits of the batting ball to the external electronic device so that the electronic device can directly display it. When adjusting the effective number of hits of the batting ball, the external electronic device can not only clear the effective number of hits of the batting ball of the batting ball, but also increase or decrease the effective number of hits of the batting ball, and can also save the current effective number of hits of the batting ball, and rank the effective number of hits of the protected batting ball.

[0041] As one embodiment, when the head mounted device 1 obtains the first detection value greater than the first set detection value, it simultaneously receives the acceleration value obtained by the striking ball 3 through the 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 opening state, and starts counting the effective hits of the striking ball 3 from the first detection value greater than the first set detection value 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 opening state, does not count the effective hits of the striking ball 3, and takes the next first detection value greater than the first set detection value as the first first detection value greater than the first set detection value obtained. When the striking ball 3 is hit, the head mounted device 1 puts the striking ball in the opening state to prevent the head mounted device 1 from making a false detection when the user wears the product.

[0042] As one embodiment, the reporting module broadcasts according to the number of hits N. When N is equal to 1, the total number of hits will be broadcast each time the hitting ball 3 is hit; when N is 10, the total number of hits will be broadcast after the hitting ball 3 is hit 10 times. The sound of the reporting module can be changed accordingly according to the number of hits, and the user can also decide which sound to use for the broadcast. The broadcasting sound can be a male voice, a female voice, a child's voice, an old man's voice, a normal voice, a funny voice, etc. The reporting module can also play music, and the user can hit the hitting ball 3 along with the music.

[0043] The combat 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 connected to the elastic rope 2 in a transmission manner. When the striking ball 3 is struck and moves forward, the sliding block 6 is driven forward by the elastic rope 2. The sliding block 6 is relatively displaced relative to the mechanism inside the head-mounted device 1. At this time, the first detection sensor detects the sliding block 6. After the sliding block 6 is displaced, the first detection sensor detects a first detection value exceeding the detection threshold, indicating that the striking ball 3 is effectively struck. When the striking ball 3 rebounds, the spring 7 restores the sliding block 6 to its original position. At this time, 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, the first detection value exceeding the detection threshold is detected again. It will be calculated as the effective number of strikes of the striking ball 3. Otherwise, it will not be calculated as the effective number of strikes. No matter how much force the user uses to strike the striking ball 3, the effective strikes of the user can be calculated, and the calculation is accurate. The counting sensor is not set on the striking ball 3, and will not be affected by the impact force when counting, and is not easy to be damaged, thereby increasing the service life of the counting sensor.
