[0007] Optionally, the connecting shaft includes a limiting protrusion, and the rotating assembly includes a top cover and a rotating member connected to each other; in the axial direction of the connecting shaft assembly, the rotating member abuts against one side of the limiting protrusion, the top cover extends in a direction away from the rotating member, and the second magnetic member is sleeved on the top cover; the connecting member is at least partially sleeved on the top cover.

[0008] Optionally, the light-emitting device further includes a protective shell, which is fitted onto the second light-emitting component; the protective shell is a transparent structure.

[0009] Secondly, this utility model provides a toy that includes the light-emitting device described above.

[0010] Optionally, the toy includes a connecting rod connected to one end of the connecting shaft assembly near the second light-emitting component; the rotating component is used for frictional rolling with the bearing surface.

[0014] The light-emitting device of this utility model includes a connecting shaft assembly, a first light-emitting component, and a second light-emitting component. The first light-emitting component includes a rotating assembly, a first magnetic induction coil, a first magnetic element, and a first lamp assembly. The first magnetic element corresponds to the position of the first magnetic induction coil. When the rotating assembly rotates, it drives the first magnetic induction coil to rotate relative to the first magnetic element, cutting magnetic field lines, thereby generating an induced current in the first magnetic induction coil and supplying power to the first lamp assembly. Furthermore, the second magnetic induction coil is disposed within the connecting member, which is fixedly connected to the connecting shaft assembly.

If the specific posture changes, the directional indications will also change accordingly.

[0023] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0024] Reference Figures 1 to 4 This application provides a light-emitting device, which includes a connecting shaft assembly 1, a first light-emitting component 2, and a second light-emitting component 3. The first light-emitting component 2 and the second light-emitting component 3 are distributed along the axial direction of the connecting shaft assembly 1. The first light-emitting component 2 includes a rotating assembly 21, a first magnetic induction coil 22, a first magnetic element 23, and a first lamp group 24. The first magnetic induction coil 22 is disposed inside the rotating assembly 21, and the rotating assembly 21 is sleeved on the connecting shaft assembly 1. The first magnetic element 23 is disposed on the connecting shaft assembly 1, and the positions of the first magnetic element 23 and the first magnetic induction coil 22 correspond. The first lamp group 24... 4 is connected to the first magnetic induction coil 22. The rotating component 21 can rotate relative to the connecting shaft assembly 1 to drive the first magnetic induction coil to rotate relative to the first magnetic element 23. The second light-emitting component 3 includes a connector 31, a second magnetic induction coil 32, a second magnetic element 33 and a second lamp group 34. The second magnetic induction coil 32 is disposed inside the connector 31. The connector 31 is fixedly connected to the connecting shaft assembly 1. The second magnetic element 33 is disposed outside the rotating component 21 and the positions of the second magnetic element 33 and the second magnetic induction coil 32 correspond. The second lamp group 34 is connected to the second magnetic induction coil 32.

[0025] According to the above structure, when the rotating component 21 rotates, it drives the first magnetic induction coil 22 to rotate relative to the first magnetic element 23, cutting the magnetic field lines, thereby generating an induced current in the first magnetic induction coil 22 and supplying power to the first lamp group 24. Furthermore, when the rotating component 21 rotates, it also drives the second magnetic element 33 to rotate relative to the second magnetic induction coil 32, cutting the magnetic field lines, thereby generating an induced current in the second magnetic induction coil 32 and supplying power to the second lamp group 34. Thus, the rotation of the rotating component 21 not only causes the first lamp group 24 of the first light-emitting component 2 to emit light, but also causes the second lamp group 34 of the second light-emitting component 3 to emit light, achieving multi-level illumination. Since the first light-emitting component 2 and the second light-emitting component 3 are distributed along the axial direction of the connecting shaft component 1, the light-emitting area of ​​the device is more three-dimensional and comprehensive, increasing the device's visual appeal. Compared to traditional light-emitting devices that use battery power, the light-emitting device of this invention is more energy-efficient, reduces production costs, and improves product competitiveness.

[0026] Reference Figure 3 and Figure 4 In some embodiments, the connecting shaft assembly 1 further includes a connecting shaft 11, a first bearing 12, and a second bearing 13. The first bearing 12 and the second bearing 13 are both sleeved on the connecting shaft 11 and are spaced apart along the axial direction of the connecting shaft assembly 1. The first bearing 12 and the second bearing 13 are connected to the rotating assembly 21. Thus, the arrangement of the two bearings can provide sufficient support for the rotating assembly 21, reduce friction, and make the rotating assembly 21 more stable when rotating.

[0027] In some embodiments, the first magnetic element 23 is sleeved on the connecting shaft 11, and the first bearing 12 and the second bearing 13 are clamped on the first magnetic element 23. Thus, the first bearing 12 and the second bearing 13 limit the first magnetic element 23, clamping and fixing the first magnetic element 23 to restrict its movement in the axial direction of the connecting shaft 11.

[0028] Reference Figure 4 In some embodiments, the connecting shaft 11 includes a limiting protrusion 14, and the rotating assembly 21 includes a top cover 211 and a rotating member 212 connected to each other. In the axial direction of the connecting shaft assembly 1, the rotating member 212 abuts against one side of the limiting protrusion 14, the top cover 211 extends in a direction away from the rotating member 212, and a second magnetic member 33 is sleeved on the top cover 211. The connecting member 31 is at least partially sleeved on the top cover 211. In some examples, the rotating assembly 21 may also include a bottom cover 213 connected to the side of the rotating member 212 away from the top cover 211.

[0029] In some embodiments, the rotating member 212 may be a wheel. In other embodiments, the rotating member 212 may also be a ball. Specifically, the rotating member 212 is made of a transparent material that allows the light from the first lamp assembly 24 to pass through.

[0030] In some embodiments, the light-emitting device further includes a protective shell 4, which is fitted onto the second light-emitting component 3; the protective shell 4 is a transparent structure. Thus, the protective shell 4 protects the second light-emitting component 3 from impacts by external components and also provides waterproofing and dustproofing. Specifically, the protective shell 4 may include a first shell and a second shell, which are connected by screws, and the connected first and second shells can enclose the second light-emitting component 3.

[0031] This application also provides a toy that includes the light-emitting device described above.

[0032] Reference Figure 1 In some embodiments, the toy includes a connecting rod 5 connected to one end of the connecting shaft assembly 1 near the second light-emitting component 3; a rotating component 21 is used for rubbing and rolling against a bearing surface. Thus, the user can hold the connecting rod 5 and press the rotating component 21 against a bearing surface such as the ground. When the rotating component 21 rolls on the ground, the first light group 24 and the second light group 34 of the toy can emit light, making it easy to operate and providing the toy with fun and an ambiance.

[0033] In some embodiments, the connecting rod 5 includes a detachably connected first connecting rod 51 and a second connecting rod 52, with the first connecting rod 51 connected to the connecting shaft 11. In other embodiments, the connecting rod 5 includes a first connecting rod 51, a second connecting rod 52, and a third connecting rod 53 that are detachably connected in sequence, with the first connecting rod 51 connected to the connecting shaft 11. Specifically, the first connecting rod 51, the second connecting rod 52, and the third connecting rod 53 can be threaded together, allowing the user to choose one or more connecting rods depending on the child's height.

[0034] In some embodiments, the toy also includes a hand ring 6, which is connected to the end of the connecting rod 5 opposite to the second light-emitting component 3. Thus, the hand ring 6 is easier for the user to hold and more convenient to use.

[0035] In some embodiments, the toy further includes a cushioning pad 7, which at least partially covers the outer wall of the hand ring 6. In some examples, the cushioning pad 7 may be a sponge. In other examples, the cushioning pad 7 may be a rubber pad. Thus, the cushioning pad 7 enhances the tactile feel of the user's hand and also provides anti-slip and shock-absorbing effects, improving the user experience.

[0036] In summary, when the rotating component 21 rotates, it drives the first magnetic induction coil 22 to rotate relative to the first magnetic element 23, cutting magnetic field lines, thereby generating an induced current in the first magnetic induction coil 22 and supplying power to the first lamp group 24. Furthermore, when the rotating component 21 rotates, it also drives the second magnetic element 33 to rotate relative to the second magnetic induction coil 32, cutting magnetic field lines, thereby generating an induced current in the second magnetic induction coil 32 and supplying power to the second lamp group 34. Thus, the rotation of the rotating component 21 not only causes the first lamp group 24 of the first light-emitting component 2 to emit light, but also causes the second lamp group 34 of the second light-emitting component 3 to emit light, achieving multi-level illumination. Since the first light-emitting component 2 and the second light-emitting component 3 are distributed along the axial direction of the connecting shaft component 1, the light-emitting area of ​​the device is more three-dimensional and comprehensive, increasing the device's visual appeal. Compared to traditional light-emitting devices that use battery power, the light-emitting device of this invention is more energy-efficient, reduces production costs, and improves product competitiveness.
