Here, at one end of the center shaft 21 in the direction in which the rope R is connected, a cap accommodating portion 25 having an accommodating groove 25S capable of accommodating the aforementioned rope fastening cap 60 is formed. It can be. In addition, an installation hole 27 through which the detachable slider 50 is installed may be formed inside the cap accommodating portion 25 in the axial direction. Inside the installation hole 27, a slider accommodating portion 23 accommodating a fixing body 51 of a detachable slider 50 to be described later may be formed.

As shown in FIGS. 3A to 5B , the detachable slider 50 is a fixed body 51 fixed to the slider accommodating portion 23 corresponding to the inside of one end of the rotor shaft 20 to prevent escape to the outside. ), a slider body 54 disposed slidably in the axial direction inside the fixed body 51, and provided on the outer surface of the slider body 54, and the rope fastening cap 60 is pushed inward in the axial direction Or, when pressed, a pair of slider hooks 53a and 53b are deformed so as to be collapsed on both sides of the hook hooking end 63 and are caught in a pair of hook hooking grooves 63a and 63b of the hook hooking end 63. can do.

On both side surfaces of the fixed body 51, body fixing hooks 52 hooked to the engaging ends 22 protruding stepwise into the slider accommodating portion 23 may be formed, respectively. When the fixing body 51 is received through the slider accommodating portion 23 through the installation hole 27, the body fixing hook 52 can be fastened with one touch through an operation in which the hook is coupled to the hooking end 22.

Meanwhile, an elastic member support boss 55 protruding and extending toward the slider body 54 may be formed in the fixed body 51 . An elastic member provided in the form of a spring spring (not shown) may be interposed on the outer circumferential surface of the elastic member support boss 55 .

Therefore, it provides the advantage of greatly improving user convenience.

On the other hand, the smart jump rope 1 according to an embodiment of the present invention, as referred to in Figure 1, can be interlocked with the user terminal of the user's portable through a wireless communication method. The smart jump rope 1 of this embodiment may further include a built-in communication component to enable real-time information communication with a user terminal through a mutual wireless communication method.

As a wireless communication method between the smart jump rope 1 and the user terminal according to this embodiment, any one of Bluetooth communication, Lora communication, and RF communication may be adopted. Preferably, device registration is possible through pairing with the smart jump rope 1 according to the present embodiment for the first time, and the user's portable user terminal may be a smartphone in which a communication component capable of Bluetooth communication may be embedded.

Here, if the user's portable user terminal is capable of device registration and Bluetooth communication as described above, one smart jump rope 1 can be registered in a plurality of user terminals, and the plurality of users can each user terminal In accordance with an embodiment of the present invention, a dedicated application provided by the manufacturer of the smart jump rope 1 through online or the like can be installed and interlocked wirelessly.

Meanwhile, the smart jump rope 1 according to an embodiment of the present invention may further include a fingerprint recognition unit 19 for identifying a specific user among a plurality of users. As described above, the fingerprint recognition unit 19 may be formed in the fingerprint pattern housing 15 that is slidably coupled to the groove cutout 19h formed on a portion of the outer circumferential surface of the main housing 11 .

When the user's fingerprint recognition operation is input through the fingerprint recognition unit 19, the power of the smart jump rope 1 is temporarily turned on, and the recognized fingerprint is registered in a dedicated application or the main board 90 ) When matching is made with that of the registered user stored in the control unit, it is possible to switch to a standby state in which a skipping rope exercise can be enjoyed based on the previous exercise record information of the registered user.

As referenced in FIG. 1 , the dedicated application provides information about the user's past exercise record, daily goal number and whether or not the record has been achieved, the current number of skipping rope exercises, and the remaining amount of the rechargeable battery through the linked user terminal. The user may be notified through text or voice. At this time, the number of first step or second step according to the skipping rope exercise pattern to be described later counted by the counting unit 70 may be displayed separately through a dedicated application.

In addition, the dedicated application can register the target number of times per day for each user, and when the target number of times per day according to the user's jumping rope exercise is reached, the user can be notified through the user terminal. A specific method of alarming can be a visual alarm through a display screen of a user terminal in which a dedicated application is installed, or an alarm can be sent out through a speaker of the user terminal. In addition, a vibration alarm method through a haptic motor 110 to be described later may also be possible through receiving information from a dedicated application or through information of the control unit of the main board 90 itself.

Here, on the main board 90, as shown in FIGS. 3A to 4 , a haptic motor 110 providing a predetermined sense of vibration to the cradle housing 10 while operating by receiving power from the rechargeable battery 80. can be combined. As will be described later, the haptic motor 110 informs the user that the number of skipping rope exercises has been reached in units of 10, 50, or 100 even before reaching the target number of times per day set by the user or reaching the target number of times per day. It can play a role of informing through senses such as haptic vibration.

In general, the jumping rope exercise method is a one-step jump that passes the rope R with one rotation, a two-step jump that passes the rope R with two turns, and a rope when the sole of the user's foot lifts off the floor once. (R) can be divided into multi-step jumps that pass the rope (R) at more than that number of turns.

Depending on the user's propensity or preference of exercise method, there may be cases in which exercise is performed mainly with single jumps or double jumps, and there may be cases in which single jumps and double jumps are used together.

The number of jump rope exercises can be counted by the counting unit 70 by the user directly distinguishing between single jump and double jump. However, there is a problem in that it is very difficult for the user to physically classify the number of skipping exercises by the user himself who prefers the exercise method of using both single and double jumps.

The smart jump rope 1 according to an embodiment of the present invention is provided to count the number of skipping ropes of the user based on the rotational angular velocity of the magnet 40 provided on the rotor shaft 20, so that each user has 1 By learning and setting the angular velocity of the single-step jump rope movement (single-step jump) and the second-step jump rope movement (two-step jump), the counting unit 70 can separately count the single-step jump and the double-step jump.

In the case of the same user, it is an acceptable fact that the rotational angular velocity of the magnet 40 detected during a single jump is generally smaller than the rotational angular velocity of the magnet 40 detected during a double jump. Therefore, the counting unit 70 counts once as the number of skipping rope movements during the double jump when a specific user is counted twice in a row with a rotational angular velocity greater than or equal to the set value than the average value of the rotational angular velocity during the single jump. can do.

In this way, the smart jump rope 1 according to an embodiment of the present invention identifies and recognizes the user through the fingerprint recognition unit 19, alarms the user's exercise information in real time through the user terminal, and haptic motor Through 110, by giving a vibration alarm that a target number of jump ropes per day or the number of jump rope exercises in a certain unit has been achieved, an advantage of encouraging the user to jump rope exercise is provided.
