Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] Such as figure 1 As shown, the micro-projection device of the embodiment of the present invention includes: a micro-projector 4 , and in order to realize the levitation of the micro-projector 4 , it also includes a main levitation magnet 3 . The micro projector 4 is fixed on the main levitation magnet 3 . The direction of the magnetic field at the center of the magnetic field of the main suspension magnet 3 is a vertical direction, which is used to suspend the micro-projector 4 in a magnetic field environment. Wherein, the micro-projector 4 may be a projection ring or other forms of projectors.

[0033] Further, a counterweight ( figure 1 The counterweight is no...

Abstract

The invention relates to the technical field of magnetic suspension and projection, and discloses a micro-projection device comprising a micro-projector. The micro-projection device is characterized by further comprises a main suspension magnet, wherein the micro-projector is fixed on the main suspension magnet; the magnetic field direction of the magnetic field center of the main suspension magnet is the vertical direction, and is used for enabling the micro-projector to suspend in a magnetic field environment. The invention also discloses a magnetic suspension base which comprises a shell and at least three base magnets located inside the shell; the magnetic field direction of the center of the combined magnetic field formed by the at least three base magnets is in the vertical direction; the magnetic field intensity of the center of the combined magnetic field is smaller than the magnetic field intensity of the combined magnetic field near each base magnet, and is used for enabling the micro-projection device to suspend. According to the invention, suspension of the micro-projector is realized in the magnetic field environment as the micro-projector is fixed on the magnet.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation and projection, in particular to a micro-projection device and a magnetic levitation base. Background technique [0002] With the development of wearable technology and micro-projector technology, someone has proposed a scheme of setting the micro-projector on a ring, that is, a ring projector (hereinafter referred to as a projection ring). Moreover, someone proposed the idea of ​​setting a magnetic levitation base for the projection ring to achieve a cool user experience. However, no one has yet proposed a specific implementation plan. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the invention is: how to make the micro-projector suspended. [0005] (2) Technical solutions [0006] In order to solve the above technical problems, the present invention provides a micro-projection device, including a micro-proje...
