[0029] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the embodiments and the accompanying drawings.

[0030] See also Figure 1 The liquid suspended light energy self-rotation device 100 of the utility model comprises a device core 10, a light-transmitting shell 20, an external suspension 30 located in the light-transmitting shell 20, and a base 40 for supporting the light-transmitting shell 20. The device core 10 is located in the light-transmitting shell 20, and the external suspension 30 is used to suspend the device core 10 in the light-transmitting shell 20; optionally, as an example, the light-transmitting shell 20 and the device core 10 are each spherical. Obviously, according to actual needs, the light-transmitting shell 20 and the device core 10 can also be other shapes, which is flexibly selected by those skilled in the art according to actual needs, so it is not limited to the following. Figure 1 The figure is limited; in addition, the light-transmitting shell 20 is a closed shell to prevent the external suspension 30 from accidentally escaping from the light-transmitting shell 20; in addition, when the light-transmitting shell 20 is made into a closed shell, at this time, in order to facilitate the installation of the device core 10 in the light-transmitting shell 20, the light-transmitting shell 20 is designed to include a first shell 20a and a second shell 20b, the first shell 20a and the second shell 20b are assembled together, and the assembly point of the first shell 20a and the second shell 20b is sealed to prevent the external suspension 30 from leaking from the assembly point; since how the first shell 20a and the second shell 20b are assembled together is already well known in the art, it will not be repeated here.

[0031] Recombination Figure 2 and Figure 3The core 10 of the device comprises a rotating shell 11, a control circuit board 12, a field magnet 13 located in the rotating shell 11, four induction coils 14 matched with the field magnet 13, a light energy board 15 for converting light energy into electric energy, a base 16 located in the rotating shell 11, a suspension 17 located in the rotating shell 11 and fixedly connected to the base 16, and an internal suspension 18 located in the rotating shell 11 to float the suspension 17 to a preset position along the direction of the rotation center line C. The base 16 and the rotating shell 11 can rotate relative to each other around a rotation center line C to meet the need that the rotating shell 11 can rotate relative to the base 16 around the rotation center line C. All the induction coils 14 are arranged separately around the rotation center line C, and all the induction coils 14 are also assembled on the base 16, and the base 16 provides a place for assembly and a support for the induction coils 14. The field magnet 13 is fixedly connected to the rotating shell 11, and the rotating shell 11 provides a place for assembly and a support for the field magnet 13. The control circuit board 12 is mounted on the base 16, and the base 16 provides a mounting place and a support for the control circuit board 12; the control circuit board 12 is also electrically connected to the light energy board 15 and the induction coil 14 (see the center line indicated by the reference numeral 122), so that the control circuit board 12 controls the light energy board 15 to regularly transmit the electric energy generated by the light energy board 15 to the induction coil 14, and the light energy board 15 is mounted on the base 16, and the base 16 provides a mounting place and a support for the light energy board 15. Specifically, Figure 1 As an example, the suspension 17 is arranged between the induction coil 14 and the light energy board 15 along its floating direction (i.e. the direction indicated by arrow A), the control circuit board 12 is arranged adjacent to the light energy board 15, and the control circuit board 12 has the same number of photoelectric switches 121 as the induction coil 14 and arranged around the rotation center line C to meet the need of one photoelectric switch 121 for controlling the power on and off (i.e. power on and power off) between the light energy board 15 and one induction coil 14; a light flux control bracket 113 for controlling the external light to irradiate on the photoelectric switch 121 is fixed in the rotating shell 11, and the light flux control bracket 113 is arranged in sequence with the photoelectric switch 121 along the floating direction of the suspension 17, so that the external light can irradiate on the light energy board 15 and the photoelectric switch 121 of the control circuit board 12; obviously, according to actual needs, the positional relationship between the induction coil 14, the light energy board 15 and the suspension 17 can also be other, so it is not used here. Figure 1 In addition, it should be noted that, although the number of the induction coils 14 described above is four, it is obvious that the number of the induction coils 14 can also be two, three or five according to actual needs, which is well known in the art and will not be described in detail here. More specifically, as follows:

[0032] like Figures 1 to 4As shown in FIG. 1 , as an example, the suspension 17 also protrudes from the base 16 in a direction perpendicular to the rotation centerline C (i.e., the direction indicated by arrow B and the opposite direction) to increase the contact area between the suspension 17 and the inner suspension 18. Figure 4 In the embodiment, as an example, the surface 17a of the suspension 17 has an outer inclined surface 172 inclined outwardly relative to the rotation center line C along the floating direction of the suspension 17 and a vertical surface 173 perpendicular to the rotation center line C. The vertical surface 173 is connected to the outer inclined surface 172. The vertical surface 173 and the outer inclined surface 172 are arranged in sequence along the floating direction of the suspension 17. The purpose of this design is to make the buoyancy of the internal suspension 18 on the suspension 17 act on the vertical surface 173 and the outer inclined surface 172. The outer inclined surface 172 is a position of the suspension 17 that is also affected by the internal suspension 18 in the floating direction. More specifically, in Figure 4 As an example, the surface 17a of the suspension 17 also has an inner inclined surface 174 inclined inwardly relative to the rotation center line C along the floating direction of the suspension 17 and a parallel surface 175 parallel to the rotation center line C. The parallel surface 175 is respectively connected to the outer inclined surface 172 and the inner inclined surface 174. The vertical surface 173, the outer inclined surface 172, the parallel surface 175 and the inner inclined surface 174 are arranged in sequence along the floating direction of the suspension 17 to effectively increase the volume of the suspension 17. In addition, the vertical surface 173 and the outer inclined surface 172 both protrude from the base 16 in a direction perpendicular to the rotation center line C to effectively increase the contact area of ​​the inner suspension 18 acting on the suspension 17.

[0033] In order to reduce the deadweight of the suspension 17, Figures 1 to 4 In the embodiment, as an example, the suspension 17 is a hollow structure so that there is a space 171 inside the suspension 17; alternatively, as an example, the suspension 17 is an airbag. Obviously, according to actual needs, the suspension 17 can also be other structures, so it is not limited to this. In addition, the suspension 17 is jacketed on the substrate 16 to increase the reliability of the fixed connection between the suspension 17 and the substrate 16. In addition, the rotating shell 11 is a light-transmitting closed structure, so that external light can pass through the rotating shell 11 and then irradiate the photoelectric switch 121 of the light energy board 15 and the control circuit board 12; obviously, according to actual needs, when the rotating shell 11 is made into a shell with an open mouth, the external light can be irradiated on the photoelectric switch 121 of the light energy board 15 and the control circuit board 12 through the open mouth, so the rotating shell 11 can be a light-proof shell. At the same time, a shielding plate 19 is fixed in the rotating shell 11 and is located between the induction coil 14 and the suspension 17. The shielding plate 19 is also arranged with a gap between the base 16 to meet the need that the shielding plate 19 rotates relative to the base 16 around the rotation center line C along with the rotating shell 11. Figure 1 and Figure 2As an example, the aforementioned shielding plate 19 is also arranged below the field magnet 13, and the shielding plate 19 is fixed in the rotating shell 11. Finally, in order to facilitate the assembly of the components (such as the base 16, etc.) in the rotating shell 11, the rotating shell 11 is designed to include a first shell 11a and a second shell 11b. The second shell 11b and the first shell 11a are assembled together, and the assembly is sealed to prevent the internal suspension 18 from leaking from the assembly. Since how the first shell 11a and the second shell 11b are assembled together is well known in the art, it will not be repeated here.

[0034] like Figures 1 to 4 As shown, as an example, a shaft body 161 is installed at the center of the base 16, and the axis of the shaft body 161 forms the rotation center line C, that is, the axis and the rotation center line C coincide; a corresponding sleeve structure 111 is provided in the rotating shell 11, which is aligned with the shaft body 161 along the floating direction of the suspension 17, and the end of the shaft body 161 is rotatably and slidably inserted into the sleeve structure 111, so as to meet the need that the rotating shell 11 can rotate around the shaft body 161 while being able to slide relative to the shaft body 161. It should be noted that when the rotating shell 11 is a light-transmitting closed structure, at this time, the sleeve structures 111 are two and are spaced and aligned from each other along the floating direction of the suspension 17, so that the shaft body 161 is located between the two sleeve structures 111, and the state is shown in FIG. Figure 1 When the rotating shell 11 is a shell with an open opening, the sleeve structure 111 is one and is arranged at one side of the rotating shell 11 away from the open opening.

[0035] like Figure 1 and Figure 3 As shown, as an example, a first magnetic adsorption structure 162 is fixed on the shaft 161, and the first magnetic adsorption structure 162 is arranged in sequence with the induction coil 14 along the floating direction of the suspension 17; correspondingly, a second magnetic adsorption structure 50 for magnetic adsorption with the first magnetic adsorption structure 162 is installed on the base 40, and the base 16 is fixed in a directional manner by means of the magnetic adsorption between the first magnetic adsorption structure 162 and the second magnetic adsorption structure 50, that is, in this state, the base 16, the light-transmitting shell 20 and the base 40 are stationary to meet the need for the rotating shell 11 to rotate around the rotation center line C under the cooperation of the control circuit board 12, the light energy board 15 and the induction coil 14. Specifically, at Figure 1 and Figure 3 As an example, the first magnetic adsorption structure 162 is a plurality of structures arranged around the rotation center line C, and the rotation center line C coincides with the center line of the second magnetic adsorption structure 50, so that the orientation and fixation of the base 16 are more reliable. Figure 1 and Figure 3As an example, the first magnetic adsorption structure 162 is fixed to the shaft 161 through the fixing seat 163, and the fixing seat 163 is also fixedly mounted on the shaft 161, so that the first magnetic adsorption structure 162 is indirectly fixed to the shaft 161. For example, at least one of the first magnetic adsorption structure 162 and the second magnetic adsorption structure 50 is a magnet. When one of the first magnetic adsorption structure 162 and the second magnetic adsorption structure 50 is a magnet, the other is a material that can be adsorbed by a magnet, such as but not limited to metal iron.

[0036] like Figure 1 and Figure 5 As shown, as an example, in order to facilitate the fixing of the field magnet 13, an annular convex ring 112 is convexly provided in the rotating shell 11, and a mounting disc frame 131 is fixed to the annular convex ring 112. The field magnet 13 is fixedly connected to the mounting disc frame 131. Figure 1 and Figure 5 shown.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, as an example, the light control bracket 113 is in the shape of an impeller, so that the light control bracket 113 can achieve the action of connecting or disconnecting the photoelectric switch 121 by blocking or removing the blocking of external light, so that the photoelectric switch 121 controls the power on and off (i.e., power on and power off) between the light energy panel 15 and the induction coil 14.

[0038] Combined with the accompanying drawings, the working principle of the liquid suspended light energy rotation device of the utility model is explained:

[0039] (1) For example Figure 7 In the embodiment, the first light energy panel 151 and the second light energy panel 152 convert the light energy irradiated thereon into electric energy, and apply the electric energy to the two ends of the corresponding photoelectric switch 121 through at least one induction coil 14;

[0040] (2) For example Figure 6 In the embodiment, under the control of the light control bracket 113, a part of the photoelectric switches 121 are blocked by the light control bracket 113, and the remaining photoelectric switches 121 are opened by the light control bracket 113 and are out of the blocking. By opening and blocking the light control bracket 113, the light is regularly irradiated to each photoelectric switch 121 on the control circuit board 12. For example, Figure 7 In the figure, from left to right, the light is sequentially irradiated on each photoelectric switch 121, ensuring that each photoelectric switch 121 is regularly turned on and off;

[0041] (3) The photoelectric switch 121 is regularly turned on and off, ensuring that the corresponding induction coil 14 is regularly powered on and off, thereby generating a force in a uniform direction in the field magnet 13;

[0042] (4) Since the induction coil 14 is mounted on the base 16 and the field magnet 13 is fixed to the rotating shell 11, the rotating shell 11 rotates around the rotation center line C under the action of the induction coil 14 and the field magnet 13 and the base 16 is fixed in a directional manner due to the magnetic attraction of the first magnetic adsorption structure 162 and the second magnetic adsorption structure 50. Therefore, under appropriate lighting conditions, the rotating shell 11 can achieve the purpose of continuous rotation relative to the light-transmitting housing 30, the base 40 and the base 16.

[0043] Compared with the prior art, by means of the suspension 17 located in the rotating shell 11 and fixedly connected to the base 16 and the internal suspension 18 located in the rotating shell 11 to float the suspension 17 to a preset position along the direction of the rotation centerline C (i.e. the direction indicated by the arrow A and the opposite direction), the buoyancy of the suspension 17 by the internal suspension 18 is used to offset the gravity of the suspension 17, the base 16, the induction coil 14, the control circuit board 12 and the light energy board 15, thereby effectively reducing the friction resistance of the relative rotation between the rotating shell 11 and the base 16, so that the rotation between the rotating shell 11 and the base 16 is more sensitive. At the same time, by means of the magnetic adsorption cooperation between the second magnetic adsorption structure 50 on the base 40 and the first magnetic adsorption structure 162 on the shaft 161, the rotation of the rotating shell 11 is effectively reduced from external interference, ensuring the reliability of the rotation of the rotating shell 11.

[0044] It is worth noting that although Figure 7 Only four photoelectric switches 121 are shown, so that each photoelectric switch 121 corresponds to an induction coil 14. Of course, according to actual needs, the number of photoelectric switches 121 can also be other. Figure 7 In addition, although the aforementioned liquid suspension light energy self-rotation device 100 of the present invention includes a base 40, it is obvious that in other embodiments, the base 40 and the second magnetic adsorption structure 50 on the base 40 can also be deleted, so it is not limited to the above description. In addition, the internal suspension liquid 18 is a liquid that does not conduct electricity.

[0045] The above disclosure is only a preferred example of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
