Description

Technical Field

[0001] This utility model relates to the technical field of jump ropes, and more specifically to a handle and jump rope for a self-illuminating jump rope. Background Technology

[0002] Jumping rope is a highly effective aerobic exercise. There are now light-up jump ropes on the market, which not only increase the fun of jumping but also enhance safety by preventing others from approaching in low-light conditions. Currently, most light-up jump ropes use batteries to power the light-up device, while some use a miniature generator to directly power it, utilizing the mechanical energy of the rope's rotation to drive the generator. Currently, jump rope handles with miniature generators have complex structures, typically using a larger stator within the generator fixed inside the handle, allowing a smaller rotor to rotate and generate electricity. This necessitates a custom-designed handle with a large inner diameter to accommodate the generator, making it inconvenient to hold; conversely, a slender handle requires a similarly slender generator, limiting the availability of commercially available miniature generators and increasing production costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a handle for a self-illuminating jump rope. It has a simple structure, can be equipped with a commercially available micro generator, and does not require increasing the inner diameter of the handle. It feels no different from an ordinary jump rope handle when held.

[0004] The technical solution of this utility model is to provide a handle for a self-illuminating jump rope, including a handle, a rotating head, a generator assembly, and a light-emitting module. The rotating head is rotatably connected to the handle. The generator assembly includes a stator and a rotor shaft. The stator is circumferentially limited within the rotating head, and the rotor shaft is circumferentially limited within the handle. A light-guiding rope end-limiting cavity is provided within the rotating head to limit the end of the light-transmitting jump rope. A rope exit hole is provided on the light-guiding rope end-limiting cavity. The light-emitting module is disposed within the rotating head and electrically connected to the generator assembly, for illuminating the end of the light-transmitting jump rope.

[0005] Compared with existing technologies, the handle for a self-illuminating jump rope of this invention has the following advantages: When jumping rope, squeezing the handle and swinging the rope causes the rotating head to rotate, which in turn causes the stator and rotor shafts to rotate relative to each other. This allows the generator assembly to convert mechanical energy into electrical energy to generate electricity, thereby powering the light-emitting module and enabling it to emit light. The stator is installed inside the rotating head and rotates with it. The diameter of the rotating head can be set to be compatible with commonly used micro generators on the market. The rotor shaft is fixed inside the handle, eliminating the need to increase the inner diameter of the handle, making the handle feel no different from a regular jump rope handle. The overall structure is simple and the production cost is low.

[0006] Preferably, the rotating head has a generator limiting cavity, and the stator is disposed within the generator limiting cavity and circumferentially limited; the handle has a bushing limiting groove communicating with the generator limiting cavity, a bushing is disposed within the bushing limiting groove and circumferentially limited by the bushing, and a rotor shaft limiting hole is disposed within the bushing, the rotor shaft is inserted into the rotor shaft limiting hole and circumferentially limited. This structure is simple and easy to assemble.

[0007] Preferably, a light-emitting module limiting part is provided above the light guide rope end limiting cavity, and the light-emitting module is limited in the light-emitting module limiting part. An LED bead is provided on the light-emitting module, and the LED bead is opposite to the light guide rope end limiting cavity. This structure facilitates the LED bead emitting light to the light-transmitting end of the jump rope.

[0008] Preferably, the light-emitting module limiting part is provided with at least two limiting posts, and the light-emitting module is provided with at least two insertion limiting holes, which are sleeved on the corresponding limiting posts. This structure facilitates the assembly of the light-emitting module.

[0009] Preferably, one end of the rotating head is provided with an annular adapter plate, and the handle is provided with an adapter groove in front of the bushing limiting groove. The annular adapter plate is disposed in the adapter groove and can rotate within the adapter groove. This structure facilitates the rotatable connection of the rotating head to the handle.

[0010] Preferably, the rotating head includes an upper cover and a lower cover, which are assembled together; the handle includes an upper shell and a lower shell, which are assembled together. With this structure, the generator assembly, the light-emitting module, and the end of the jump rope can be installed on the upper or lower cover first, and then the upper and lower covers can be assembled. Afterward, the rotating head and rotor shaft can be installed on the upper or lower shell first, and then the upper and lower shells can be assembled. Assembly is simple and easy to operate.

[0011] Preferably, both the upper and lower covers have at least three corresponding screw holes, and the upper and lower covers are connected by screws; both the upper and lower shells have at least three corresponding screw holes, and the upper and lower shells are connected by screws. This structure, using at least three screws to connect the upper and lower covers, ensures the rotating head is stable and secure, preventing cracking under stress; similarly, using at least three screws to connect the upper and lower shells ensures the handle is stable and secure, preventing cracking under stress.

[0012] Preferably, the limiting cavity at the end of the light guide rope is located on the side of the rotating head. With this structure, when the jump rope is swung by squeezing the handle, the rotating jump rope is basically perpendicular to the handle. By setting the limiting cavity at the end of the light guide rope on the side of the rotating head, that is, the jump rope is connected to the side of the rotating head, the torque of the rotating jump rope on the rotating head is maximized, which facilitates the jump rope to drive the rotating head to rotate.

[0013] Preferably, the light-emitting module includes a circuit board with a rectifier circuit on it. The rectifier circuit converts the pulse current generated by the generator assembly into direct current. With this structure, the light-emitting module can emit light regardless of whether the stator rotates in the forward or reverse direction relative to the rotor shaft.

[0014] This utility model also provides a jump rope. The technical solution includes a light guide rope assembly and two handles for self-illuminating jump ropes as described above. The light guide rope assembly includes a rope body and two rope end fixing members. The ends of the rope body are detachably connected to the rope end fixing members. The rope end fixing members are limited within the limiting cavity of the light guide rope end, and the rope body passes through the rope body outlet hole. With this structure, the stator is installed inside the rotating head, and the diameter of the rotating head can be set to be compatible with commercially available micro generators, so that the jump rope of this utility model can be equipped with commercially available micro generators. The rotor shaft is fixed inside the handle, eliminating the need to increase the inner diameter of the handle, making the handle feel no different from an ordinary jump rope handle. The overall structure is simple and the production cost is low. When jumping rope, the hand squeezes the handle and swings the jump rope, which drives the rotating head to rotate. This causes the stator and rotor shaft to rotate relative to each other, and the generator assembly can convert mechanical energy into electrical energy to generate electricity, thereby powering the light-emitting module and enabling the light-emitting module to emit light.
