All of the induction coils 14 are arranged in common and spaced about the center line of rotation C, with all of the induction coils 14 also mounted on the base 16, with the base 16 providing a location and support for the mounting of the induction coils 14.

Specifically, in fig. 1, as an example, the suspension 17 is disposed between the induction coil 14 and the optical energy plate 15 along the floating direction (i.e. the direction indicated by the arrow a), the control circuit board 12 and the optical energy plate 15 are disposed adjacent to each other, and the control circuit board 12 has the same number of the photoelectric switches 121 as the induction coils 14 and are arranged around the rotation center line C at intervals, so as to meet the requirement that one photoelectric switch 121 is used for controlling the power on/off (i.e. powering on and powering off) between the optical energy plate 15 and one induction coil 14, the rotary housing 11 is internally fixed with the light-passing control bracket 113 for controlling the external light to irradiate the photoelectric switch 121, and the light-passing control bracket 113 is sequentially disposed along the floating direction of the suspension 17 and the photoelectric switch 121 so that the external light irradiates the optical energy plate 15 and the photoelectric switch 121 of the control circuit board 12, and obviously, according to the actual requirement, the positional relationship between the induction coils 14, the optical energy plates 15 and 17 can be other than that shown in fig. 1, and it is also required that although the number of induction coils 14 is four, the number of induction coils 14 is obviously not known, two or three are needed. More specifically, the following is:

As shown in fig. 1 to 4, as an example, the suspension 17 also protrudes from the substrate 16 in a direction perpendicular to the rotation center line C (i.e., a direction indicated by an arrow B and a direction opposite thereto) to increase a contact area between the suspension 17 and the inner suspension 18. Specifically, in FIG. 4, 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 in the floating direction of the suspension 17 and a vertical surface 173 perpendicular to the rotation center line C, the vertical surface 173 being connected to the outer inclined surface 172, the vertical surface 173 and the outer inclined surface 172 being arranged in this order in the floating direction of the suspension 17, the purpose being so designed that the buoyancy of the suspension 17 by the inner suspension 18 acts on the vertical surface 173 and the outer inclined surface 172, the outer inclined surface 172 being a position where the suspension 17 also has an effect of the inner suspension 18 in the floating direction. More specifically, in fig. 4, as an example, the surface 17a of the suspension 17 further has an inner inclined surface 174 inclined inwardly with respect to the rotation center line C in the floating direction of the suspension 17 and a parallel surface 175 parallel to the rotation center line C, the parallel surface 175 being connected to the outer inclined surface 172 and the inner inclined surface 174, respectively, and the vertical surface 173, the outer inclined surface 172, the parallel surface 175 and the inner inclined surface 174 being arranged in this order in the floating direction of the suspension 17 to effectively increase the volume of the suspension 17, and in addition, the vertical surface 173 and the outer inclined surface 172 are each projected 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 on the suspension 17.

In order to reduce the dead weight of the suspension 17, in fig. 1 to 4, as an example, the suspension 17 is in a hollow structure so that the space 171 is formed inside the suspension 17, alternatively, as an example, the suspension 17 is an air bag, it is obvious that the suspension 17 can have other structures according to practical needs, and therefore the invention is not limited thereto. In addition, the suspension 17 is sleeved on the substrate 16 to increase the reliability of the fixed connection of the suspension 17 and the substrate 16. In addition, the rotary housing 11 is a light-transmitting closed structure, so that external light passes through the rotary housing 11 and irradiates the light energy plate 15 and the photoelectric switch 121 of the control circuit board 12, and obviously, when the rotary housing 11 is made into a housing with an opening according to practical needs, the external light can irradiate the light energy plate 15 and the photoelectric switch 121 of the control circuit board 12 through the opening, so the rotary housing 11 can be a light-proof housing. Meanwhile, a shielding plate 19 is fixed in the rotary housing 11 between the induction coil 14 and the suspension 17, the shielding plate 19 is also arranged with a jacket in clearance with the base 16 to meet the requirement that the shielding plate 19 rotates relative to the base 16 along with the rotary housing 11 around the rotation center line C, and in fig. 1 and 2, as an example, the shielding plate 19 is also arranged below the field magnet 13, and the shielding plate 19 is fixed in the rotary housing 11. Finally, to facilitate assembly of components (e.g., the base 16, etc.) within the rotary housing 11 at the rotary housing 11, the rotary housing 11 is designed to include a first housing 11a and a second housing 11b, the second housing 11b and the first housing 11a being assembled together, and the assembly being sealed to prevent leakage of the inner suspension 18 from the assembly, since how the first housing 11a and the second housing 11b are assembled together is well known in the art, and will not be described in detail herein.

As shown in fig. 1 to 4, as an example, a shaft body 161 is mounted at the center of the base body 16, the shaft axis of the shaft body 161 forms a rotation center line C, that is, the shaft axis coincides with the rotation center line C, a shaft sleeve structure 111 aligned with the shaft body 161 along the floating direction of the suspension 17 is correspondingly provided in the rotary housing 11, and the end of the shaft body 161 is rotatably and slidably inserted into the shaft sleeve structure 111 so as to meet the requirement that the rotary housing 11 can rotate around the shaft body 161 and can slide relative to the shaft body 161. It should be noted that when the rotary housing 11 is a light-transmitting closed structure, the shaft sleeve structures 111 are two and aligned at a distance from each other in the floating direction of the suspension 17, so that the shaft body 161 is located between the two shaft sleeve structures 111, as shown in fig. 1, and when the rotary housing 11 is a housing having an opening, the shaft sleeve structures 111 are one and disposed at a side of the rotary housing 11 away from the opening.

As shown in fig. 1 and 3, as an example, the shaft body 161 is fixed with a first magnetic attraction structure 162, the first magnetic attraction structure 162 is sequentially arranged with the induction coil 14 along the floating direction of the suspension 17, correspondingly, the base 40 is provided with a second magnetic attraction structure 50 for magnetically attracting the first magnetic attraction structure 162, and the base 16 is fixed in an oriented manner by the magnetic attraction between the first magnetic attraction structure 162 and the second magnetic attraction structure 50, that is, in this state, the base 16, the light-transmitting shell 20 and the base 40 are stationary, so as to meet the requirement that the rotary housing 11 rotates 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, in fig. 1 and 3, as an example, the first magnetic attraction structure 162 is a plurality of magnetic attraction structures spaced around the rotation center line C, and the rotation center line C coincides with the center line of the second magnetic attraction structure 50, so that the orientation of the substrate 16 is fixed more reliably. More specifically, in fig. 1 and 3, as an example, the first magnetic attraction structure 162 is fixed on the shaft body 161 through the fixing base 163, and the fixing base 163 is further fixedly sleeved on the shaft body 161, so that the first magnetic attraction structure 162 is indirectly fixed at the shaft body 161. For example, when at least one of the first magnetic attraction structure 162 and the second magnetic attraction structure 50 is a magnet, the other is a material that can be attracted by the magnet, such as but not limited to metallic iron.

As shown in fig. 1 and 5, as an example, in order to facilitate the fixation of the field magnet 13, the rotary housing 11 is internally provided with an annular convex ring 112 in a protruding manner, the annular convex ring 112 is fixed with a mounting disc frame 131, and the field magnet 13 is fixedly connected with the mounting disc frame 131, and the state is shown in fig. 1 and 5.

As shown in fig. 1, 5 and 6, as an example, the light-passing control bracket 113 is in an impeller shape, so that the light-passing control bracket 113 can achieve the action of turning on or off the photoelectric switch 121 by shielding or unhindering external light, so that the photoelectric switch 121 can control the on/off (i.e. power on and off) between the light energy plate 15 and the induction coil 14.

The working principle of the liquid suspension optical energy autorotation device of the utility model is described with reference to the accompanying drawings:

(1) For example, in fig. 7, the first and second optical energy plates 151 and 152 convert optical energy irradiated thereon into electric energy, which is applied to both ends of the corresponding photoelectric switch 121 through at least one induction coil 14;

(2) For example, in fig. 6, under the control of the light-passing control bracket 113, a part of the photoelectric switches 121 are blocked by the light-passing control bracket 113, and the rest of the photoelectric switches 121 are opened by the light-passing control bracket 113 to be separated from the blocking, so that the light is regularly irradiated to each photoelectric switch 121 on the control circuit board 12 in a mode of opening and blocking the light-passing control bracket 113, for example, in fig. 7, from left to right, so that the light is sequentially irradiated to each photoelectric switch 121, and each photoelectric switch 121 is ensured to be regularly turned on and off;

(3) The photoelectric switch 121 is regularly turned on and off to ensure that the corresponding induction coil 14 is regularly energized and de-energized, thereby generating a force in a uniform direction in the field magnet 13;

(4) Because the induction coil 14 is assembled on the base 16 and the field magnet 13 is fixed on the rotary housing 11, under the acting force between the induction coil 14 and the field magnet 13 and under the oriented fixation of the base 16 due to the magnetic attraction of the first magnetic attraction structure 162 and the second magnetic attraction structure 50, the rotary housing 11 rotates around the rotation center line C, so that under proper illumination, the continuous rotation of the rotary housing 11 relative to the light-transmitting housing 30, the base 40 and the base 16 can be realized.

Compared with the prior art, by means of the suspension 17 which is positioned in the rotary shell 11 and fixedly connected with the base 16 and the inner suspension 18 which is positioned in the rotary shell 11 to float the suspension 17 to a preset position along the direction of the rotation center line C (namely, the direction indicated by the arrow A and the opposite direction), the gravity of the suspension 17, the base 16, the induction coil 14, the control circuit board 12 and the optical energy board 15 is counteracted by the buoyancy of the inner suspension 18 to the suspension 17, so that the frictional resistance of relative rotation between the rotary shell 11 and the base 16 is effectively reduced, and the rotation between the rotary shell 11 and the base 16 is more sensitive. Meanwhile, by means of the magnetic attraction cooperation of the second magnetic attraction structure 50 on the base 40 and the first magnetic attraction structure 162 on the shaft body 161, the rotation of the rotary housing 11 is effectively lightened from external interference, and the reliability of the rotation of the rotary housing 11 is ensured.

It should be noted that although fig. 7 only shows four photoelectric switches 121, each photoelectric switch 121 corresponds to one induction coil 14, and of course, the number of photoelectric switches 121 may be other according to actual needs, and thus is not limited to that shown in fig. 7. In addition, although the liquid suspension optical rotation device 100 of the present utility model includes the base 40, it is obvious that in other embodiments, the base 40 and the second magnetic adsorption structure 50 on the base 40 can be omitted, and thus the description is not limited thereto. In addition, the inner suspension 18 is a non-electric liquid.

The foregoing disclosure is only illustrative of the preferred embodiments of the present utility model and is not to be construed as limiting the scope of the utility model, which is defined by the appended claims.
