Detailed Description

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, a jump rope 100 includes a handle 11 and a rope body 12. The handle 11 is in a long cylinder shape, and the handle 11 is provided with two handles, which correspond to the left hand and the right hand of a user. As one implementation, the handle 11 may be shaped in other ways and the shape of the design should fit the hand of the user. The rope body 12 is connected to the handles 11, one end of the rope body 12 is connected to one of the handles 11, the other end of the rope body 12 is connected to the other handle 11, and when a user uses the skipping rope to move, the rope body 12 rotates around the handles 11. As an implementation manner, the rope body 12 may be provided with two sections, one end of one section of rope body 12 is connected to one of the handles 11, one end of the other section of rope body 12 is connected to the other handle 11, the other end of each section of rope body 12 is connected to a counterweight ball, and the weight of the counterweight ball can be adjusted according to the requirements of users, so that the requirements of different users are met, namely the application range of the jump rope of the invention is enlarged.

Referring to fig. 2, a weight 13, a motor 14 and a transmission structure 15 are provided on the handle 11. Wherein, balancing weight 13 activity sets up in handle 11, and transmission structure 15 is connected with motor 14, and transmission structure 15 also is connected with balancing weight 13, and motor 14 operation can drive balancing weight 13 activity through transmission structure 15 to make balancing weight 13 be close to the user hand or keep away from the user hand. Wherein, the two handles 11 are provided with a balancing weight 13, a motor 14 and a transmission structure 15, so that the two handles 11 have the same load on the hands of a user.

Referring to fig. 2 and 3, the driving structure 15 includes a lead screw 151, a screw hole 152, and a guide groove 153. Wherein, the guide groove 153 is arranged in the handle 11, and the balancing weight 13 can move along the guide groove 153. The lead screw 151 can rotate around its axis, and lead screw 151 one end is connected on motor 14, and motor 14 operation drives lead screw 151 rotation, and the lead screw 151 other end rotates to be connected on guide slot 153 inner wall, and lead screw 151 rotates to be connected on guide slot 153 inner wall can increase the position quantity that lead screw 151 and handle 11 are connected to improve the intensity of lead screw 151, reduce the possibility that leads to transmission structure 15 to become invalid because lead screw 151 damages. The screw hole 152 is arranged on the balancing weight 13, the screw rod 151 corresponds to the screw hole 152, the screw rod 151 penetrates through the screw hole 152, the guide groove 153 limits the movable mode of the balancing weight 13, and the guide groove 153 limits the circumferential rotation of the balancing weight 13, so that when the motor 14 drives the screw rod 151 to rotate, the screw rod 151 rotates to drive the balancing weight 13 to move through the cooperation of the screw rod 151 and the screw hole 152.

Referring to fig. 2, the handle 11 is further provided with a grip portion 16, and the grip portion 16 is used for providing a hand grip for a user. Specifically, the holding portion 16 includes a groove 161, the groove 161 is recessed toward the inside of the handle 11, and the contact area between the hand of the user and the handle 11 can be increased by the finger of the user holding the groove 161, so that the friction force can be increased by increasing the friction area, and the handle 11 is prevented from being released. Under the condition that the hand pressure is constant, the contact area between the hand of the user and the handle 11 is increased, and the pressure intensity of the hand of the user can be effectively reduced, so that the grasping comfort of the handle 11 is improved. And the shape of the groove 161 corresponds to the outline of the finger of the user's hand, so that the finger of the user can be effectively placed in the groove 161. And the grooves 161 may be provided with four corresponding to the four fingers of the user's hand except for the thumb. As an implementation, the number of grooves 161 may be more than four, so that the user's hands can be held at different positions on the handle 11, thereby improving versatility.

Referring to fig. 2, the weight 13 can be moved back and forth between a first position and a second position, specifically, by translating the weight 13 along the inner wall of the guide groove 153. When the weight 13 moves to the first position, the weight 13 approaches the holding portion 16. When the user uses the rope skipping motion with the weight 13 in the first position, the load of the user's hand holding the handle 11 is minimized. When the weight 13 moves from the first position to the second position, the weight 13 is away from the holding portion 16, and the weight 13 is close to the connection portion between the handle 11 and the rope 12. When the user uses the rope skipping motion in this state, since the weight 13 is far away from the user's hand, that is, the distance between the weight 13 and the user's hand increases. When the user's hand drives the handle 11 to rotate, the larger the radius of rotation of the handle 11 part far from the user's hand, the larger the centrifugal force is when the handle 11 part far from the user's hand rotates under the condition that other conditions are unchanged, namely the condition that the angular velocity of rotation of the handle 11 is unchanged. I.e. the weight 13 is moved to the second position, the radius along with the rotation of the handle 11 is increased, i.e. the centrifugal force is increased, so that the load of the hand of the user for holding the handle 11 is increased, and the purpose of enhancing the movement effect is achieved.

Referring to fig. 2, it can be appreciated that the handle 11 is also provided with a storage capacitor 17 and a charging port 18. The storage capacitor 17 is electrically connected with the motor 14, and the storage capacitor 17 can provide electric energy to the motor 14, so as to drive the motor 14 to operate. The charging port 18 is electrically connected with the storage capacitor 17, one end of the charging port 18 is arranged on the handle 11, the opening of the charging port 18 is positioned on the round side surface or the end surface of the handle 11, and the end surface is far away from the joint of the handle 11 and the rope body 12. The present embodiment provides the opening direction of the charging port 18 on the end face in such a manner that it can be applied to a jump rope having an excessively narrow width of the handle. The arrangement of the storage capacitor 17 improves the convenience of rope skipping, namely, when a user uses the rope skipping to move, the movement control of the balancing weight 13 can be realized without an external power supply. The design of the charging port 18 improves the convenience of rope skipping, namely when the rope skipping is in a non-working state, an external power supply is connected to the charging port 18 through an electric transmission line, and electric energy provided by the external power supply can be transmitted into the storage capacitor 17, so that the electric energy is converted into chemical energy to be stored in the storage capacitor 17. As an implementation manner, the charging port 18 may be replaced by a plug, the plug is electrically connected with the storage capacitor 17, and the plug can be inserted into the plug-in port to transmit external electric energy to the storage capacitor 17, so that it can be understood that the plug is movably connected to the handle 11, and when charging is not needed, a user can manually drive the plug to move into the handle 11, so that the use and placement of the rope skipping handle 11 are prevented from being influenced by the plug, and the safety is improved. When the user uses the skipping rope to move, the user needs to disconnect the charging port 18 from the electric transmission line, so that the user can use the skipping rope to move conveniently. As an implementation, the connection between the electric transmission line and the charging port 18 is not released when the user uses the rope skipping motion, so that the purpose of synchronous charging when the user uses the rope skipping motion is achieved, and the implementation can be aimed at the situation that the chemical energy of the storage capacitor 17 is insufficient.

As an implementation, a battery compartment may be disposed in the handle 11 and electrically connected to the motor 14, such that when the battery is placed in the battery compartment, the battery provides electrical power to the motor 14.

Referring to fig. 2, it can be appreciated that the handle 11 is further provided with a rotating table 19 and a power generation device 20. Wherein, the rotating table 19 is rotatably connected to the handle 11, and the rotating table 19 extends out of the end surface of the handle 11, and the rope 12 is connected to the part of the rotating table 19 extending out of the handle 11. And the power generation device 20 is arranged on the handle 11, the rotating table 19 stretches into the power generation device 20, and the rotating table 19 rotates to drive the power generation device 20 to generate power, namely, the mechanical energy is converted into electric energy. The power generation device 20 is electrically connected with the storage capacitor 17, and the power generation device 20 can generate power to transmit the power to the storage capacitor 17. The design of the charging structure can convert kinetic energy of a user in rope skipping into electric energy, and finally converts the electric energy into chemical energy to be stored in the storage capacitor 17, so that electric energy consumption is reduced.

Referring to fig. 2 and 4, a jump rope 100 further includes a heart rate sensor 21, the heart rate sensor 21 is disposed on the handle 11, the heart rate sensor 21 is disposed on the outer side of the handle 11, and the heart rate sensor 21 is disposed between the grip portion 16 and the rotating table 19, thereby conforming to ergonomics. I.e. the four fingers of the user's hand, except for the thumb, are held in the four grooves 161 and the thumb extends to the side of the turntable 19 and presses against the heart rate sensor 21. And heart rate sensor 21 is annular, installs on handle 11 circle side, and heart rate sensor 21 is annular can increase heart rate sensor 21 and the success rate of user's hand contact, avoids the rope skipping midway user's hand and heart rate sensor 21 break away from. Wherein the heart rate sensor 21 is arranged on at least one of the handles 11. As one implementation, the heart rate sensor 21 is provided in two and is provided on the two handles 11, respectively.

Referring to fig. 2 and 5, the motor 14 is controlled by an electronic terminal 22, which electronic terminal 22 may be a cell phone, a personal computer, an iPad, etc. And the electronic terminal 22 includes an input module 221 and a data processor 222. The user can input data through the input module 221 to transmit the data to the data processor 222. It will be appreciated that the input module 221 is used to input the age of the user. The data input by the input module 221 may be manually input by a user, may be input by a sound by the user, or may be input by other modes. The manual input mode of the input module 221 may be a mode of pressing a button or an intelligent touch screen. And after the heart rate sensor 21 is contacted with the user, the heart rate sensor 21 senses the heart rate of the user and transmits signals to the data processor 222. The connection of the heart rate sensor 21 to the data processor 222 includes, but is not limited to, a bluetooth connection. The data processor 222 can receive the data input by the input module 221 and the signal transmitted by the heart rate sensor 21, process and calculate the data and the signal, and further has the signal change transmitted by the heart rate sensor 21, and finally control the motor 14 to operate. It will be appreciated that the data processor 222 controls the motors 14 located in both handles 11, and that the data processor 222 controls the motion of both motors 14 to be the same. The manner in which the electronic terminal 22 controls the operation of the motor 14 includes, but is not limited to, the electronic terminal 22 being capable of switching on or off the electrical circuit between the reservoir 17 and the motor 14, thereby achieving the purpose of the electronic terminal 22 controlling the operation of the motor 14, i.e., the purpose of the electronic terminal 22 controlling the movement of the weight 13. The electronic terminal 22 can control the motor 14 to operate so as to drive the screw 151 to rotate forward or reversely, when the screw 151 rotates forward, the balancing weight 13 moves to the second position, and when the screw 151 rotates reversely, the balancing weight 13 moves to the first position. As one implementation, when the screw 151 rotates forward, the weight 13 moves to the first position, and when the screw 151 rotates backward, the weight 13 moves to the second position.

The data processor 222 processes the data as calculated as follows:

APMHR (maximum heart rate) =220—age of rope-jumpers;

HRR (heart rate reserve) =apmhr (maximum heart rate) -RHR (quiet heart rate);

for example, an adult male aged 25 years, with his RHR (resting heart rate) 80 monitored by heart rate sensing before exercise, his APMHR (maximum heart rate) =220-rope skipping age 220-25=195, so his heart rate reserve HRR is APMHR (maximum heart rate) -RHR (resting heart rate) 195-80=115, and thus, weight 13 moves between the first and second positions in response to changes in the young man heart rate. And when the heart rate of the young and the male reaches 195, the balancing weight 13 moves to the second position, and if the heart rate of the young and the male continues to rise, the balancing weight 13 does not displace. It can be understood that when the young man heart rate increases, the balancing weight 13 moves to the second position, when the young man heart rate decreases, the balancing weight 13 moves to the first position, the change amount of the young man heart rate and the moving distance of the balancing weight 13 are positively correlated, and the relationship curve of the change amount of the young man heart rate and the moving distance of the balancing weight 13 is a straight line. As an implementation manner, the relationship curve of the change amount of the heart rate of the young and the moving distance of the balancing weight 13 may be other lines, so as to improve the exercise effect generated by the user using the rope skipping exercise.

The specific implementation steps of the skipping rope are as follows:

the user inputs age through the input module 221, and the input template receives age data and transmits the age data to the data processor 222. The left and right hands of the user each grip one handle 11, and the four fingers of the user's hand except the thumb grip the grooves 161, and at the same time, the thumb presses on the heart rate sensor 21 arranged in a ring shape. After the heart rate sensor 21 is in contact with the thumb, the heart rate sensor 21 can detect the heart rate of the user and transmit the heart rate to the data processor 222, which is a quiet heart rate. The user starts to train by using the jump rope, the rope body 12 drives the rotating table 19 to rotate, the rotating table 19 rotates to convert mechanical energy into electric energy through the power generation device 20, and the converted electric energy is converted into chemical energy, and the chemical energy is stored in the storage capacitor 17. When the heart rate rises due to rope skipping training, the heart rate sensor 21 detects the heart rate of the user in real time, the rising of the heart rate of the user represents that the user is approaching to end, and the data processor 222 controls the motor 14 to operate according to the data change of the heart rate sensor 21, namely, the lead screw 151 is driven to rotate positively, and the lead screw 151 is driven to move positively through the cooperation of the lead screw 151 and the threaded hole 152. The weight 13 is initially located at the first position, i.e. the weight 13 is initially close to the grip portion 16, and the weight 13 is moved from the first position to the second position, i.e. the weight 13 is away from the grip portion 16, i.e. the weight 13 is away from the user's hand, thereby increasing the centrifugal force, i.e. the load of the user's hand gripping the handle 11. After the load of the handle 11 on the hand of the user is increased, the effect of rope skipping training of the user can be enhanced. Meanwhile, according to the change process of the rope skipping load of a user from light to heavy, the mode can drive the adductor hallux on the hand, the extensor hallux on the small arm, the extensor hallux on the large arm, the triceps brachii, the biceps brachii and other muscle groups, meanwhile, in the rope-volatilizing jumping process, the rope-volatilizing jumping process also can exercise the chest, abdomen, lower leg, thigh and hip muscle groups along with variable-speed weights of different weights, and through the continuous change of the weight, the tight body can be provided with a breathing process from light to heavy to light along with the variable-speed weights, the rope-skipping effect is further added, and the variable-speed movement concept is further added, so that the movement is more effective and more beneficial to human body exercise.

During training, when the heart rate sensor 21 detects that the heart rate of the user is reduced, the data processor 222 can control the motor 14 to operate to drive the screw 151 to rotate reversely, the screw 151 rotates reversely to drive the balancing weight 13 to move through the cooperation of the screw 151 and the threaded hole 152, and the balancing weight 13 moves to the first position, namely, the balancing weight 13 is close to the holding part 16, namely, the balancing weight 13 is close to the hand of the user, so that the load of the handle 11 on the user is reduced. The mode can realize the regulation of handle 11 load, namely the user can be according to self training demand, and self-adjusting handle 11 is to the load of its hand to improve training effect.

After training, the heart rate sensor 21 detects that the hands of the user are separated from the heart rate sensor 21, namely, the heart rate sensor 21 stops detecting the heart rate of the user, the data processor 222 receives the signal, the motor 14 is controlled to operate to drive the screw rod 151 to rotate reversely, the screw rod 151 rotates reversely to drive the balancing weight 13 to move through the cooperation of the screw rod 151 and the threaded hole 152, and the balancing weight 13 moves to the first position, namely, the balancing weight 13 is close to the holding part 16. When the weight 13 moves to the first position, the weight 13 returns to the initial position, so that the subsequent use of the subsequent rope skipping is facilitated. As an implementation manner, after the hands of the user are separated from the heart rate sensor 21, the heart rate sensor 21 is still in an operation state, and the heart rate sensor 21 is not in contact with the user, so that the heart rate sensor 21 transmits a signal to the data processor 222, the data processor 222 can control the motor 14 to operate through the signal and drive the screw 151 to rotate reversely, the screw 151 rotates reversely to drive the balancing weight 13 to move through the cooperation of the screw 151 and the threaded hole 152, and the balancing weight 13 moves to the first position. When the weight 13 moves to the first position, the data processor 222 ends control of the motor 14.

In the prior art, a common rope skipping has the function of changing the load, for example, in a cordless rope skipping, the weight of a counterweight ball connected to a rope body is changed to change the load when a user jumps the rope, but the mode can be implemented only after the user stops the rope skipping, when the user uses the rope skipping to move, the load of the rope skipping to the user cannot be adjusted in real time by the user, and the mode is unfavorable for the user to jump the body in the early stage, so that the training effect of the rope skipping is reduced. In the jump rope of the invention, the counterweight 13 is arranged in the handle 11, and the counterweight 13 can move in the handle 11. The heart rate of the user is detected by the heart rate sensor 21 and data analysis is performed by the electronic terminal 22, so that the movement of the balancing weight 13 is controlled. When the weight 13 is far away from the hand of the user and the weight 13 is close to the joint of the handle 11 and the rope 12, the weight of the handle 11 is unchanged, and the centrifugal force of the handle 11 is increased, so that the load of the user for gripping the handle 11 is increased. The jump rope of this embodiment can change the load of the handle 11 on the user's hand during the jump rope. The jump rope of this mode can improve the warm-up effect of user's jump rope initial stage, and after the user's rhythm of the heart improves, handle 11 load increases, helps the training of user later stage to the phase change improves training effect. The invention has simple structure and obvious effect, and is suitable for mass production.

The preferred embodiments of the present invention have been described in detail, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention, and the various changes are included in the scope of the present invention.
