Description

Technical Field

[0001] The present invention relates to the technical field of rope skipping, and in particular to a rope skipping handle, a rope skipping and a rope skipping counting method. Background Art

[0002] Chinese documents CN108211198A, CN202538233U and CN211635033U all disclose skipping rope structures that use Hall sensors for counting. However, during use, existing skipping ropes are often tripped by the feet and cannot be rotated to a certain angle to continue swinging the rope for skipping. The rotation or swinging back and forth of the rope may cause the Hall sensor to be falsely triggered, resulting in counting errors, affecting the accuracy of the skipping rope counting. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a rope skipping handle, which mainly solves the technical problem that the number of turns of the rope skipping handle is easily calculated due to the back-and-forth rotation and shaking of the rope body, resulting in erroneous counting.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:

[0005] A skipping rope handle comprises a grip and a rotating part rotatably connected to the grip, wherein a first Hall sensor and a second Hall sensor are arranged opposite to each other on the grip, and a magnet is arranged on the rotating part corresponding to the first Hall sensor and the second Hall sensor and capable of rotating synchronously with the rotating part. The first Hall sensor is defined to output a low level (0') when triggered by the magnet and a high level (1') when not triggered, and the second Hall sensor is defined to output a low level (0") when triggered by the magnet and a high level (1") when not triggered. The number and installation positions of the magnets on the rotating part are configured such that when the magnet rotates one circle with the rotating part, the first Hall sensor and the second Hall sensor can cooperate to generate a set of counting cycle data consisting of at least four signal states in sequence: (0', 0"), (0', 1"), (1', 1"), and (1', 0")

[0006] Furthermore, the magnet installed on the rotating part includes a first magnetic part and a second magnetic part, and the first magnetic part and the second magnetic part are arranged at a certain angle on the rotating part. The installation positions of the first magnetic part and the second magnetic part on the rotating part are configured as follows: when the first magnetic part and the second magnetic part rotate one circle with the rotating part, the first Hall sensor and the second Hall sensor can cooperate to generate a set of counting cycle data consisting of eight signal states in sequence: (0', 0"), (0', 1"), (1', 1"), (0', 1"), (1', 1"), (1', 0"), (1', 1") and (1', 0").

[0007] Furthermore, the plane where the first Hall sensor and the second Hall sensor are located and the plane where the first magnetic part and the second magnetic part are located are configured to be parallel to each other, so that a front-to-back corresponding setting structure is formed between the Hall sensor and the magnetic part, or the plane where the first Hall sensor and the second Hall sensor are located and the plane where the first magnetic part and the second magnetic part are located are configured to overlap with each other, so that a circumferential corresponding setting structure is formed between the Hall sensor and the magnetic part.

[0008] Furthermore, the midpoint of the line connecting the first Hall sensor and the second Hall sensor and the rotation axis of the first magnetic component and the second magnetic component are eccentrically arranged.

[0009] Furthermore, the interval angle between the first magnetic member and the second magnetic member on the rotating portion is 90° to 150°.

[0010] Furthermore, when the Hall sensor and the magnetic part are arranged in a front-to-back corresponding structure, the vertical projections of the first Hall sensor and the second Hall sensor are located on the circular motion path of the first magnetic part and the second magnetic part. At the same time, the distance between the first Hall sensor and the second Hall sensor is slightly smaller than the diameter of the circular motion path of the first magnetic part and the second magnetic part, so that the vertical projection of the line connecting the first Hall sensor and the second Hall sensor does not pass through the rotation axis of the first magnetic part and the second magnetic part, and the first Hall sensor and the second Hall sensor are configured to be able to be triggered simultaneously by the corresponding first magnetic part and the second magnetic part to generate a (0', 0") signal state.

[0011] Furthermore, when the Hall sensor and the magnetic part are arranged in a circumferentially corresponding structure, the first Hall sensor and the second Hall sensor are relatively arranged on the outer side of the circular motion path of the first magnetic part and the second magnetic part, and the connecting line between the first Hall sensor and the second Hall sensor does not pass through the rotation axis of the first magnetic part and the second magnetic part, and the first Hall sensor and the second Hall sensor are configured to be able to be triggered simultaneously by the corresponding first magnetic part and the second magnetic part to generate a (0', 0") signal state.

[0012] Furthermore, the magnet on the rotating part is an arc-shaped long magnetic piece, and the planes where the first Hall sensor and the second Hall sensor are located are parallel to the plane where the arc-shaped long magnetic piece is located, so that a front-to-back corresponding setting structure is formed between the Hall sensor and the magnetic piece, or the planes where the first Hall sensor and the second Hall sensor are located are overlapped with the plane where the arc-shaped long magnetic piece is located, so that a circumferential corresponding setting structure is formed between the Hall sensor and the magnetic piece, the midpoint of the line between the first Hall sensor and the second Hall sensor and the rotation axis of the arc-shaped long magnetic piece are an eccentric setting structure, and the length of the arc-shaped long magnetic piece and the installation position of the arc-shaped long magnetic piece on the rotating part are configured as follows: when the arc-shaped long magnetic piece rotates one circle with the rotating part, the first Hall sensor and the second Hall sensor can cooperate to generate a set of counting cycle data consisting of four signal states in sequence: (0', 0"), (0', 1"), (1', 1") and (1', 0").

[0013] Based on the same inventive concept, the present invention also provides a skipping rope, comprising a first skipping rope handle and a second skipping rope handle, the first skipping rope handle and the second skipping rope handle being connected by a rope body, the first skipping rope handle and / or the second skipping rope handle being any of the skipping rope handles described above, wherein the grip of the skipping rope handle comprises an outer shell and a PCB board fixedly arranged inside the cavity of the outer shell, the first Hall sensor and the second Hall sensor are relatively fixedly arranged on the PCB board and electrically connected to the PCB board, a rope body connection hole is formed on the outer end of the rotating part, a bearing is fixedly arranged at the open end of the outer shell, the inner end of the rotating part is adapted to pass through the bearing and extend into the interior of the outer shell cavity, and a magnet fixing part is connected to the inner end of the rotating part, which is arranged corresponding to the first Hall sensor and the second Hall sensor and can rotate coaxially with the rotating part, and the magnet is embedded in the magnet fixing part.

[0014] Based on the same inventive concept, the present invention also provides a rope skipping counting method, comprising the following steps: configuring the (0', 0") signal state generated when both the first Hall sensor and the second Hall sensor are triggered by a magnet as a counting signal acquisition starting point; and when the magnet rotates synchronously with the rotating part, after obtaining a set of sequential counting cycle data generated by the first Hall sensor and the second Hall sensor in cooperation, calculating one rotation of the rotating part.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] In the skipping rope handle, skipping rope and skipping rope counting method described in the present invention, a magnet is provided on the rotating part, and at the same time, a first Hall sensor and a second Hall sensor corresponding to the magnet are provided on the handle. When the magnet rotates synchronously with the rotating part, the moving magnet can trigger the first Hall sensor and the second Hall sensor corresponding to it in sequence, and enable the first Hall sensor and the second Hall sensor to cooperate to generate a set of counting cycle data consisting of at least four signal states in sequence: (0', 0"), (0', 1"), (1', 1") and (1', 0"); only when the first Hall sensor and the second Hall sensor cooperate to generate a complete set of counting cycle data, is it calculated that the rotating part has rotated one circle relative to the handle; if the acquired data lacks any signal state in the counting cycle data or is not generated in the predetermined order of the cycle signal, the rotating part will not be counted as having rotated one circle, which can greatly improve the counting accuracy of the number of rotations of the rotating part in the skipping rope handle, and can effectively improve the error counting caused by the back-and-forth rotation and shaking of the rope body during the skipping rope movement, which is caused by the magnet erroneously triggering the Hall sensor.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0033] Example 1

[0034] Please refer to the attached Figure 1 To the attached Figure 3An embodiment of the present invention provides a skipping rope handle, comprising a grip 1 and a rotating part 2 rotatably connected to the grip 1, the grip 1 being provided with a first Hall sensor 3 and a second Hall sensor 4 arranged opposite to each other, the rotating part 2 being provided with a magnet 5 arranged corresponding to the first Hall sensor 3 and the second Hall sensor 4 and capable of rotating synchronously with the rotating part 2, and defining that the first Hall sensor 3 outputs a low level (0') when triggered by the magnet 5, and outputs a high level (1') when the first Hall sensor 3 is not triggered, the second Hall sensor 4 outputs a low level (0") when triggered by the magnet 5, and outputs a high level (1") when the second Hall sensor 4 is not triggered, and the number and installation position of the magnet 5 on the rotating part 2 are configured such that when the magnet 5 rotates one circle with the rotating part 2, the first Hall sensor 3 and the second Hall sensor 4 can cooperate to generate a set of counting cycle data consisting of at least four signal states in sequence: (0', 0"), (0', 1"), (1', 1") and (1', 0") It can be understood that, in this embodiment, a magnet 5 is provided on the rotating part 2, and at the same time, a first Hall sensor 3 and a second Hall sensor 4 corresponding to the magnet 5 are provided on the handle 1. When the magnet 5 rotates synchronously with the rotating part 2, the moving magnet 5 can trigger the first Hall sensor 3 and the second Hall sensor 4 corresponding thereto in sequence, and enable the first Hall sensor 3 and the second Hall sensor 4 to cooperate to generate a set of counting cycle data consisting of at least four signal states in sequence: (0', 0"), (0', 1"), (1', 1") and (1', 0"), and these four different signal states are equivalent to four verification points. Only when the first Hall sensor 3 and the second Hall sensor 4 cooperate to generate a complete set of counting cycle data is obtained, Only after the counting cycle data is obtained, it is calculated that the rotating part 2 has rotated one circle relative to the handle 1. In one of the preferred application scenarios, the (0', 0") signal state can be configured as the starting point for counting signal acquisition, that is, only when the (0', 0") signal state is obtained, the acquisition signal is opened, and when a complete set of cycle data of (0', 0")→(0', 1")→(1', 1")→(1', 0")→(0', 0") is obtained, it is calculated that the rotating part 2 has rotated one full circle relative to the handle 1. During the reverse motion, only after a complete set of cycle data of (0', 0")→(1', 0")→(1', 1")→(0', 1")→(0', 0") is obtained, it is calculated that the rotating part 2 has reversed one full circle relative to the handle 1.In this way, during the rope skipping exercise, the rotation of the rotating part 2 will be recorded as a valid rotation and then calculated as one circle only after the first Hall sensor 3 and the second Hall sensor 4 cooperate to generate a sequential cycle data. If the acquired data lacks any signal state in the counting cycle data or is not generated in the predetermined order of the cycle signal, the rotating part 2 will not be counted as one circle. In this way, the counting accuracy of the number of rotations of the rotating part 2 in the rope skipping handle can be greatly improved, and the error counting caused by the back-and-forth rotation and shaking of the rope body during the rope skipping exercise can be effectively improved.

[0035] In addition, those skilled in the art should understand that the starting point for collecting the counting signal of the counting cycle data can be any one of the four signal states of (0', 0"), (0', 1"), (1', 1") and (1', 0") constituting the counting cycle data, and is not limited to the implementation method in which (0', 0") is the starting point for collecting the counting signal, that is, the counting cycle signal can also be (0', 1") → (1', 1") → (1', 0") → (0', 0") → (0', 1") or (1', 1") → (1', 0") → (0', 0") → (0', 1") → (1', 1") or (1', 0") → (0', 0") → (0', 1") → (1', 1") → (1', 0")).

[0036] In this embodiment, preferably, the first Hall sensor 3 and the second Hall sensor 4 can be omnipolar Hall sensors. In this way, there is no need to consider the magnetic pole direction of the magnet 5, thereby improving the installation convenience of the magnet 5.

[0037] Please refer to the attached Figure 1 To the attached Figure 3In one preferred embodiment, the magnet 5 installed on the rotating part 2 includes a first magnetic member 51 and a second magnetic member 52, and the first magnetic member 51 and the second magnetic member 52 are arranged at a certain angle on the rotating part 2, and the circular motion path formed by the first magnetic member 51 and the second magnetic member 52 as the rotating part 2 rotates and sweeps out coincides with each other, and the installation position of the first magnetic member 51 and the second magnetic member 52 on the rotating part 2 is configured as follows: when the first magnetic member 51 and the second magnetic member 52 rotate one circle with the rotating part 2, the first Hall sensor 3 and the second Hall sensor 4 can cooperate to generate a set of counting cycle data consisting of eight signal states in sequence: (0', 0"), (0', 1"), (1', 1"), (0', 1"), (1', 1"), (1', 0"), (1', 1") and (1', 0"). It can be understood that in this embodiment, the magnet 5 includes a first magnetic member 51 and a second magnetic member 52 arranged on the rotating part 2 at a certain angle. During the rope skipping movement, the first magnetic member 51 and the second magnetic member 5 are configured to rotate synchronously with the rotating part 2 and alternately trigger the first Hall sensor 3 and the second Hall sensor 4, so that the first Hall sensor 3 and the second Hall sensor 4 can cooperate to generate counting cyclic data consisting of eight signal states in sequence: (0', 0"), (0', 1"), (1', 1"), (0', 1"), (1', 1"), (1', 0"), (1', 1") and (1', 0"). These eight signal states are equivalent to eight verification points. Only when the first Hall sensor 3 and the second Hall sensor 4 cooperate to generate a complete set of counting cycle data, can the rotating part 2 be calculated to have rotated one circle relative to the handle 1. In one of the better application scenarios, the (0', 0") signal state can be configured as the starting point for collecting counting signals, that is, only when the (0', 0") signal state is obtained, the collection signal is opened, and when a complete set of cycle data (0', 0") → (0', 1") → (1', 1") → (0', 1") → (1', 1") → (1', 0") → (1', 1") → (1', 0") → (0', 0") is obtained, the counting signal is collected. Only after the first Hall sensor 3 and the second Hall sensor 4 cooperate to generate a sequential cycle data, will it be calculated that the rotating part 2 has rotated a full circle relative to the handle 1. In this way, during the rope skipping exercise, the rotation of the rotating part 2 will be recorded as a valid rotation and then calculated as one circle. If the acquired data lacks any signal state in the counting cycle data or is not generated in the predetermined order of the cycle signal, the rotating part 2 will not be counted as one circle. At the same time, the setting of eight verification points further improves its counting accuracy, which can effectively avoid the error counting caused by the magnet mistakenly triggering the Hall sensor due to the back and forth rotation and shaking of the rope body during the rope skipping exercise.

[0038] In this embodiment, preferably, the first magnetic member 51 and the second magnetic member 52 may be metal magnets. However, those skilled in the art should understand that in other embodiments, the first magnetic member 51 and the second magnetic member 52 may also be plastic magnets or other permanent magnetic structural members.

[0039] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, the plane where the first Hall sensor 3 and the second Hall sensor 4 are located and the plane where the first magnetic member 51 and the second magnetic member 52 are located are configured to be parallel to each other and form a front-to-back corresponding arrangement structure between the Hall sensor and the magnetic member (such as the front-to-back corresponding arrangement structure of the Hall sensor and the magnetic member shown in the prior art CN202538233U).

[0040] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, the midpoint of the line connecting the first Hall sensor 3 and the second Hall sensor 4 and the rotation axis of the first magnetic member 51 and the second magnetic member 52 are eccentrically arranged. Preferably, the spacing angle between the first magnetic member 51 and the second magnetic member 52 on the rotating portion 2 is 90° to 150°. In this embodiment, further, the spacing angle between the first magnetic member 51 and the second magnetic member 52 on the rotating portion 2 is 120°. Those skilled in the art should understand that in other embodiments, the eccentric distance between the midpoint of the line connecting the first Hall sensor 3 and the second Hall sensor 4 and the rotation axis of the first magnetic member 51 and the second magnetic member 52 is correlated with the spacing angle between the first magnetic member 51 and the second magnetic member 52 on the rotating portion 2. When the eccentric distance between the midpoint of the line connecting the first Hall sensor 3 and the second Hall sensor 4 and the rotation axis of the first magnetic member 51 and the second magnetic member 52 is larger, the spacing angle between the first magnetic member 51 and the second magnetic member 52 on the rotating portion 2 is smaller in correlation, while also satisfying the requirement that the first Hall sensor 3 and the second Hall sensor 4 can The corresponding first magnetic member 51 and the second magnetic member 52 are simultaneously triggered to generate a (0', 0") signal state. In this embodiment, preferably, the vertical projections of the first Hall sensor 3 and the second Hall sensor 4 are located on the circular motion path of the first magnetic member 51 and the second magnetic member 52. At the same time, the distance between the first Hall sensor 3 and the second Hall sensor 4 is slightly smaller than the diameter of the circular motion path of the first magnetic member 51 and the second magnetic member 52, so that the vertical projection of the line between the first Hall sensor 3 and the second Hall sensor 4 does not pass through the rotation axis of the first magnetic member 51 and the second magnetic member 52, and the first Hall sensor 3 and the second Hall sensor 4 can be simultaneously triggered by the corresponding first magnetic member 51 and the second magnetic member 52 to generate a (0', 0") signal state.

[0041] Please refer to the attached Figure 1To the attached Figure 3 An embodiment of the present invention also provides a skipping rope, comprising a first skipping rope handle and a second skipping rope handle, the first skipping rope handle and the second skipping rope handle being connected by a rope body, the first skipping rope handle and / or the second skipping rope handle being any of the skipping rope handles described above, wherein the grip 1 of the skipping rope handle comprises an outer shell 11 and a PCB board 12 fixedly arranged inside the cavity of the outer shell 11, the first Hall sensor 3 and the second Hall sensor 4 are relatively fixedly arranged on the PCB board 12 and electrically connected to the PCB board 12, a rope body connection hole 21 is formed on the outer end of the rotating part 2, a bearing 13 is fixedly arranged at the open end of the outer shell 11, the inner end of the rotating part 2 is adapted to pass through the bearing 13 and extend into the cavity of the outer shell 11, and a magnet fixing part 22 is connected to the inner end of the rotating part 2, which is arranged corresponding to the first Hall sensor 3 and the second Hall sensor 4 and can rotate coaxially with the rotating part 2, and the magnet 5 is embedded in the magnet fixing part 22.

[0042] Please refer to the attached Figure 1 To the attached Figure 3 An embodiment of the present invention further provides a skipping rope counting method, which is applied to counting the number of rotations of the skipping rope handle and / or the skipping rope, and comprises the following steps: configuring the (0', 0") signal state generated when both the first Hall sensor 3 and the second Hall sensor 4 are triggered by the magnet 5 as the starting point for collecting the counting signal, and in the process of synchronous rotation of the magnet 5 with the rotating part 2, after obtaining a set of sequential counting cycle data generated by the cooperation of the first Hall sensor 3 and the second Hall sensor 4, calculating one rotation of the rotating part 2. For the counting cycle data consisting of four signal states, when a complete set of cycle data of (0', 0") → (0', 1") → (1', 1") → (1', 0") → (0', 0") is obtained, it is calculated that the rotating part 2 has rotated one full circle relative to the handle 1. As for the counting cycle data composed of eight signal states, when a complete set of cycle data of (0', 0") → (0', 1") → (1', 1") → (0', 1") → (1', 1") → (1', 0") → (1', 1") → (1', 0") → (0', 0") is obtained, it is calculated as the rotating part 2 rotating one full circle relative to the handle 1. In addition, it can be understood that since the counting cycle data is formed by a combination of multiple signal states in sequence, among which, for the counting cycle data composed of eight signal states, some signal states are repeated, but there is only one signal state (0', 0"), therefore, configuring it as the signal collection starting point and the signal collection end point for counting one circle can effectively reduce the calculation amount and difficulty of counting.
