Embodiment approach 1

[0037] The first embodiment of the present application provides a projector, see figure 1 , figure 2 shown, including:

[0038] The upper body 1 and the lower body 2, and the damping shaft 3 connecting the upper body 1 and the lower body 2, wherein the upper body 1 is provided with an optical machine 4, and the upper body 1 can be turned over relative to the lower body 2 through the damping shaft 3;

[0039] The upper body 1 faces The surface of the lower body 2 is the first surface 11, and the surface of the lower body 2 facing the upper body 1 is the second surface;

[0040] The projector also includes: a first magnet 51 arranged on the first surface 11 and a second magnet 52 arranged on the second surface;

[0041] A repulsive force can be generated between the first magnet 51 and the second magnet 52 for providing support to the upper body 1 .

[0042] For a projector, when it is divided into an upper body 1 and a lower body 2, components can be installed in the uppe...

Embodiment approach 2

[0058] The second embodiment of the present application also provides a projector. The second embodiment is different from the first embodiment. The main difference is that in the first embodiment of the present application, the first magnet 51 and Both the second magnets 52 are permanent magnets; however, in the second embodiment of the present application, the first magnets 51 and the second magnets 52 may not be permanent magnets.

[0059] Specifically, at least one of the first magnet 51 and the second magnet 52 can be an electromagnet.

[0060] The electromagnet has the characteristic of generating magnetic force after electrification, and can provide a directional support effect for the projector of the present application when needed.

[0061] For example, when the projector is plugged into the power source, the electromagnet can start to work. After the user adjusts the angle of the upper body 1 , the magnetic force provided by the electromagnet can support the weight...

Embodiment approach 3

[0079] The third embodiment of the present application also provides a projector. The third embodiment is different from the second embodiment. The main difference is that in the second embodiment of the present application, the sensor is used as a distance sensor It is described as an example; however, in the second embodiment of the present application, the sensor may be other types of sensors.

[0080] For example, in this embodiment, the sensor is a grating encoder, and the grating encoder is used to obtain the rotation angle of the damping shaft 3 .

[0081] Grating encoder is a digital sensor integrating optical, mechanical and electrical technologies. It can measure rotation angle or linear displacement with high precision. It has the advantages of high measurement accuracy and strong anti-interference ability, and is widely used in high-precision displacement measurement. At present, grating encoders have been widely used, and a typical application is the scroll wheel ...

Abstract

The invention relates to the technical field of display equipment, and discloses a projector which comprises an upper machine body, a lower machine body and a damping rotating shaft connected with the upper machine body and the lower machine body. An optical machine is arranged in the upper machine body, and the upper machine body can overturn relative to the lower machine body through the damping rotating shaft; and the surface, opposite to the lower machine body, of the upper machine body is a first surface, and the surface, opposite to the upper machine body, of the lower machine body is a second surface. The projector further comprises a first magnet arranged on the first surface and a second magnet arranged on the second surface. Repulsive force can be generated between the first magnet and the second magnet so as to support the upper machine body. The projector provided by the embodiment of the application has a longer service life.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a projector. Background technique [0002] A projector (also known as a projector) is a device that can project images or videos onto a curtain or wall. Projectors can usually be connected to multimedia devices such as PCs, mobile phones, play boxes, game consoles, and DVs through different interfaces to play corresponding video signals. Compared with LCD TVs, the size of the image projected by the projector is not limited by the size of the LCD and has a good sharing effect, so it is widely used in homes, offices, schools and entertainment venues. [0003] In the prior art multimedia projectors, the light engine is often relatively fixed in the casing, and the output angle of the picture cannot be adjusted, and it is quite unchanged when used in an unfixed scene. [0004] In view of this, the Chinese invention patent with the application number of 2010101261871 disclos...
