Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports equipment technology, and in particular to an AI-based jump rope counting measuring instrument. Background Technology
[0002] Rope skipping has become a physical education component of the middle school entrance examination in some regions. To ensure the fairness of the examination, it is necessary to ensure the accuracy of rope skipping statistics.
[0003] In existing technology, the counting work is mainly carried out by a built-in rotation counter in the jump rope handle. The rotation counter counts once for every one rotation of the rope. At the same time, the rotation counter inside the jump rope is connected to an external computer. The rotation counter transmits the collected data to the computer, which then completes the subsequent information processing.
[0004] The counting method using a rotating counter cannot determine whether the user has made mistakes such as stepping on the rope, so as to deduct the corresponding number of rotations. In addition, due to the different grip angles of the user, the timing of the rotating counter's jump occurs at different points in time, sometimes at the beginning of the action and sometimes at the end of the action, which may lead to errors in the measurement results. Utility Model Content
[0005] The purpose of this invention is to provide an AI-based jump rope measuring instrument. This AI-based jump rope measuring instrument can determine whether there is an error in the rope-stepping action by measuring the speed, and can position the rope through the positioning groove to unify the counting time point, thus effectively increasing the accuracy of the measurement results.
[0006] This utility model provides an AI-based jump rope counting measuring instrument, comprising:
[0007] The handle consists of a fixed block, a connecting rod, and a grip section from left to right. The diameter of the connecting rod is smaller than that of the fixed block and the grip section, giving the handle an annular groove. There are two handles, and the two ends of the rope are respectively inserted into the annular groove and wound around the connecting rod of the two handles.
[0008] The fixing block is provided with a positioning groove, and the positioning grooves on the two handles are symmetrical in shape.
[0009] A laser speed sensor is included. The handle has an integrated circuit built into it. The laser speed sensor is electrically connected to the integrated circuit. The laser speed sensor is located below the positioning groove and is embedded in the fixing block. The laser emitted by the laser speed sensor is horizontally placed in the annular groove.
[0010] Before the rope skipping exercise begins, each end of the rope is inserted into the positioning groove. During the rope skipping exercise, the rope rotates around the connecting rod and passes through the laser emitted by the laser speed sensor.
[0011] Preferably, the positioning groove is composed of a snap-in section and a disengagement section connected in series. The depth of the positioning groove varies uniformly from shallow to deep. The depth of the snap-in section is greater than that of the disengagement section. The snap-in section is laterally connected to the annular groove, and the disengagement section is longitudinally connected to the outer surface of the fixing block.
[0012] Preferably, the connecting rod is equipped with a bearing, and the rope is wound around the bearing.
[0013] Preferably, a baffle is integrally formed on the outer ring of the bearing, the baffle being annular and located near the gripping section.
[0014] Preferably, the diameter of the baffle is smaller than the diameter of the gripping section, and the difference between the diameters of the baffle and the gripping section does not exceed the thickness of the baffle.
[0015] Preferably, an auxiliary laser velocity sensor is also embedded in the fixing block. The auxiliary laser velocity sensor is evenly distributed along the annular groove, and the laser emitted by the auxiliary laser velocity sensor is horizontally placed in the annular groove.
[0016] Preferably, the laser emitting heads of both the laser velocity sensor and the auxiliary laser velocity sensor are retracted below the outer surface of the fixed block.
[0017] Preferably, the integrated circuit includes a data processing chip, a power supply, and an LCD screen, wherein the data processing chip is electrically connected to the laser velocity sensor and the auxiliary laser velocity sensor.
[0018] Preferably, the AI-counted jump rope measuring instrument further includes an angular velocity sensor, which is fixedly connected to the side of the fixed block away from the connecting rod.
[0019] Preferably, the gripping section is provided with a counterweight, and the gripping section is a rotating body with a material embedding hole at the center, and the counterweight is fixedly assembled in the material embedding hole.
[0020] The technical solution of this utility model involves creating a positioning groove and positioning the rope before the jump rope exercise begins to ensure that the starting point of the rope is consistent, thereby avoiding the influence of the grip position on the measurement results. When the rope sweeps across the laser emitted by the laser speed sensor, the laser speed sensor completes the speed measurement. Each speed measurement result corresponds to one rotation of the rope. The magnitude of the speed measurement result can be used to determine whether the user has made a mistake, and to determine whether the result is valid. This allows for the deduction of the number of incorrect rotations, ultimately improving the accuracy of the measurement results. Attached Figure Description

[0033] Combination Figures 1 to 6 As shown, the jump rope measuring instrument with AI counting provided by this utility model includes a handle 1 and a laser speed sensor 2.
[0034] Combination Figures 1 to 6 As shown, the handle 1 consists of a fixed block, a connecting rod, and a grip section from left to right. The diameter of the connecting rod is smaller than that of the fixed block and the grip section, giving the handle 1 an annular groove. There are two handles 1, with the two ends of the rope extending into the annular groove and wrapped around the connecting rod of the two handles 1. The fixed block has a positioning groove 11, which is symmetrical in shape on the two handles 1. The handle 1 has an integrated circuit built in it, and the laser speed sensor 2 is electrically connected to the integrated circuit. The laser speed sensor 2 is located below the positioning groove 11 and embedded in the fixed block. The laser emitted by the laser speed sensor 2 is horizontally positioned in the annular groove. Before the rope skipping begins, one end of each rope is inserted into the positioning groove 11. During the rope skipping, the rope rotates around the connecting rod and passes through the laser emitted by the laser speed sensor 2.
[0035] In this embodiment, by opening the positioning groove 11 and positioning the rope before the jump rope exercise begins, the starting point of the rope is consistent, thereby avoiding the influence of the grip position on the measurement result. When the rope sweeps across the laser emitted by the laser speed sensor 2, the laser speed sensor 2 completes the speed measurement. Each speed measurement result corresponds to one rotation of the rope. The magnitude of the speed measurement result can be used to determine whether the user has made a mistake, and to determine whether the result is valid. The number of incorrect rotations is deducted, and the accuracy of the measurement result is ultimately improved.
[0036] In some embodiments, combined with Figure 1 , Figure 4 As shown, the positioning groove 11 is composed of a snap-in section and a pull-out section connected in series. The depth of the positioning groove 11 changes uniformly from shallow to deep. The depth of the snap-in section is greater than that of the pull-out section. The snap-in section is laterally connected to the annular groove, and the pull-out section is longitudinally connected to the outer surface of the fixing block. By designing the shape of the positioning groove 11, the rope can be more smoothly released when it is snapped into the positioning groove 11 and swinging. At the same time, the stability of the rope snapping into the positioning groove 11 can also be increased.
[0037] In some embodiments, combined with Figure 2 , Figure 4 and Figure 5 As shown, the connecting rod is equipped with a bearing 3, and the rope is wound around the bearing 3. The bearing 3 reduces the friction force received by the rope during rotation, making the rotation smoother and improving the user experience.
[0038] In some embodiments, combined with Figure 2 , Figure 4 and Figure 5 As shown, a baffle 31 is integrally formed on the outer ring of the bearing 3. The baffle 31 is circular and close to the grip section. When the rope swings, it will naturally gather towards the center, causing friction on the grip section. Adding the baffle 31 can prevent the rope from rubbing against the grip section. At the same time, since the baffle 31 is set on the bearing 3, the baffle 31 will rotate synchronously with the rope, reducing the wear of the rope.
[0039] In some embodiments, combined with Figure 2 , Figure 4 and Figure 5 As shown, the diameter of the baffle 31 is smaller than the diameter of the grip section, and the difference in diameter between the baffle 31 and the grip section does not exceed the thickness of the baffle 31. The grip section is where the user holds the hand, and the baffle 31 is against the edge of the grip section, and the two rotate relative to each other, posing a risk of crushing the user's hand. The corner gap formed by the height difference design can play a protective role, while the height difference should not be too large to avoid the rope rubbing against the grip section.
[0040] In some embodiments, combined with Figure 2 , Figure 4 and Figure 6 As shown, an auxiliary laser speed sensor 21 is also embedded in the fixed block. The auxiliary laser speed sensor 21 is evenly distributed along the annular groove, and the laser emitted by the auxiliary laser speed sensor 21 is horizontally placed in the annular groove. By increasing the number of speed sensors 21, the speed of the rope can be more clearly understood during the entire rope skipping process, making it easier for users to understand their own movement.
[0041] In some embodiments, combined with Figure 2 , Figure 4 and Figure 6 As shown, the laser emitting heads of both the laser velocity sensor 2 and the auxiliary laser velocity sensor 21 are retracted below the outer surface of the fixed block. The retraction design protects the laser emitting heads from being hit by the rope, while also effectively reducing interference from external light sources.
[0042] In some embodiments, combined with Figure 3 As shown, the integrated circuit includes a data processing chip, a power supply, and an LCD screen. The data processing chip is electrically connected to the laser speed sensor 2 and the auxiliary laser speed sensor 21. The integrated circuit is responsible for collecting data from the laser speed sensor 2 and the auxiliary laser speed sensor 21, and also for data transmission with the computer. Wireless data transmission is an ideal method to reduce interference with the rope skipping exercise. Meanwhile, the internal power supply provides energy to the entire circuit, and the LCD screen helps the user understand the working status of the integrated circuit and view the collected information.
[0043] In some embodiments, combined with Figure 2 , Figure 6 As shown, the AI counting jump rope measuring instrument also includes an angular velocity sensor 4, which is fixedly connected to the side of the fixed block away from the connecting rod. The angular velocity sensor 4 can collect the motion state of the user's hand position.
[0044] In some embodiments, combined with Figure 5 As shown, the grip section is equipped with a counterweight 5 inside. The grip section is a rotating body with a embedded hole at the center. The counterweight 5 is fixedly installed in the embedded hole. The counterweight 5 can be used to adjust the center of gravity of the handle 1 as a whole, so as to avoid the center of gravity shift caused by the internal structure design and improve the user experience.
[0045] Working process: The user holds the grip section of handle 1, and after positioning both ends of the rope using positioning grooves 11, assumes a ready position, at which point the rope needs to remain within the positioning grooves 11; then begins the rope skipping exercise, and the rope leaves the positioning grooves 11 during the swing, and the rope will move away from the fixed block under the action of the swing, ensuring that the positioning grooves 11 do not affect the normal swing of the rope; during the rope swing, when the rope passes through the laser emitted by the laser speed sensor 2, the laser speed sensor 2 measures the speed of the rope, and each measurement result corresponds to a type of rope swing, and the validity of the action is determined by the magnitude of the measurement result.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
