Abstract
Description
Technical Field
[0001] This utility model relates to the field of photoelectric sensing technology, and in particular to a device for calculating the rotational speed of a wrist ball based on photoelectric sensing. Background Technology
[0002] A wrist ball, also known as a power ball, magic ball, spinning ball, or super spinning top, is a fitness ball that uses wrist rotation to spin the core at high speed, generating powerful force. The rhythm and speed of the rotation can be adjusted manually; the faster the speed, the greater the force. The powerful force generated by the high-speed rotation of the wrist ball is very helpful in training the strength and flexibility of the fingers, wrists, and arms, combining exercise, entertainment, and fitness. Therefore, the rotation speed of the wrist ball is an important indicator. By monitoring the rotation speed, users can better understand their abilities and progress, and develop corresponding training plans and goals. Real-time monitoring of the wrist ball's rotation speed is necessary. However, existing wrist balls cannot calculate the rotation speed, so users cannot judge their abilities or progress, affecting the development of training plans and goals, and the overall user experience.
[0003] Therefore, there is an urgent need to improve the existing wrist ball so that it can calculate the rotation speed, allowing users to understand their own abilities. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Example 1
[0031] like Figure 1 and Figure 2 As shown, the device for calculating the rotational speed of a wrist ball based on photoelectric sensing provided by this utility model includes:
[0032] An inertial metal sphere 10; a housing 50 disposed outside the inertial metal sphere 10; a rotation shaft 20 disposed on any axis of the inertial metal sphere 10, the inertial metal sphere 10 rotating along the rotation shaft 20; a light signal generator 30 disposed on the inertial metal sphere 10, the light signal generator 30 being used to emit light signals; a receiver 40 disposed on the housing 50, after the light signal generator 30 and the receiver 40 intersect, the receiver 40 receiving the light signal and generating a rising edge; a timer electrically connected to the receiver 40, used to calculate the time interval for the receiver 40 to receive the light signal; and a controller electrically connected to the receiver 40 and the timer, the controller being configured to calculate the rotational speed of the inertial metal sphere 10 based on the time interval.
[0033] This invention, through the cooperation of an optical signal generator 30, a receiver 40, a timer, and a controller, can calculate the rotational speed of an inertial metal ball 10, allowing users to intuitively see the changes in rotational speed. This enables them to judge their own abilities and progress, and to formulate training plans and goals accordingly, thus improving the user experience.
[0034] The receiver 40, timer, and controller are mounted on the circuit board 60. The receiver 40 circuit also includes a display 70, electrically connected to the controller, for displaying the rotational speed of the inertial metal ball 10. This allows the user to more intuitively see the changes in rotational speed.
[0035] The circuit board 60 is fixedly mounted inside the housing 50. Since the receiver 40 needs to interact with the light signal generator 30, the receiver 40 needs to be mounted inside the housing 50 and in a position that the light signal generator 30 can access. The display 70 needs to display the rotation speed so that the user can see it. Therefore, it can be mounted outside the housing 50, in a position that does not affect the use of the wrist ball, or it can be mounted inside the housing 50 so that the user can view the rotation speed in real time.
[0036] The rising edge can be converted into a pulse signal on the circuit board 60. Specifically, the optical signal generator 30 continuously emits optical signals. After the optical signal generator 30 and the receiver 40 intersect, a rising edge is generated and continues during the intersect. After the optical signal generator 30 moves away from the receiver 40, a falling edge is generated and continues until the optical signal generator 30 and the receiver 40 intersect again. Thus, a pulse signal is generated, and the time interval calculated by the timer is one cycle of the pulse signal.
[0037] In this preferred embodiment, the outer casing 50 is made of insulating material, thus preventing electric shock during use.
[0038] In this preferred embodiment, the outer shell 50 is made of transparent material, so that the rotation of the inertial metal ball 10 can be seen directly, and the rotational speed displayed on the display 70 can also be seen.
[0039] In this preferred embodiment, both ends of the rotating shaft 20 are fixed to the outer casing 50. This ensures that the inertial metal ball 10 rotates along the rotating shaft 20. Preferably, both ends of the rotating shaft 20 are arc-shaped, which allows for better contact with the interior of the outer casing 50.
[0040] The outer casing 50 has a hole, which exposes a portion of the inertial metal ball 10. In use, the user must first move the exposed portion of the inertial metal ball 10 so that the inertial metal ball 10 begins to rotate.
[0041] Example 2
[0042] This utility model also provides a scheme for calculating the rotational speed using the device for calculating the rotational speed of a wrist ball based on photoelectric sensing as described in Embodiment 1, including:
[0043] Move the inertial metal ball 10 to make it rotate;
[0044] Optical signal generator 30 emits a signal;
[0045] When the optical signal generator 30 and the receiver 40 meet, the receiver 40 receives the optical signal and generates a rising edge;
[0046] The timer calculates the time interval t for the receiver 40 to receive the optical signal;
[0047] The controller calculates the current rotational speed of the wrist ball, r = 1 / t, based on the time interval t.
[0048] When the optical signal generator 30 and the receiver 40 intersect, the receiver 40 receives the optical signal and generates a rising edge. Specifically, the optical signal generator 30 continuously emits optical signals. After the optical signal generator 30 and the receiver 40 intersect, a rising edge is generated and continues during the intersect. After the optical signal generator 30 moves away from the receiver 40, a falling edge is generated and continues until the next intersect between the optical signal generator 30 and the receiver 40, thus generating a pulse signal.
[0049] The time interval t for receiving optical signals is one pulse period.
[0050] This invention, through the cooperation of an optical signal generator, receiver, timer, and controller, can calculate the rotational speed of an inertial metal ball, allowing users to intuitively see the changes in rotational speed. This enables them to judge their own abilities and progress, and to formulate training plans and goals, thus improving the user experience.
[0051] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
