Problems solved by technology

[0004] like figure 1 As shown, the traditional projector mainly adopts the direct projection method, and the projection screen is located in front of the lens, and the viewers can only watch through the screen set in front, and the maneuverability is poor during actual use.
[0005] In addition, limited by the working principle of the direct projection method, there should be a predetermined distance between the lens and the screen to meet the needs of clear projection. If the predetermined distance between the lens and the screen is satisfied, a clear projection cannot be displayed

Embodiment 1

[0043] See figure 2 , which shows a schematic diagram of the overall structure of the electronic device described in the embodiment.

[0044]The opto-mechanical system of the electronic device is used to form projection light toward the first direction A according to the display data signal, and the housing 10 of the electronic device on the exit path of the projection light is provided with a first opening 11, so as to form a first opening 11 on the projection surface. image. Specifically, the optomechanical system can choose any one of liquid crystal projection system (LCD), digital optical projection system (DLP), liquid crystal on silicon projection system (LCOS) or laser scanning system (Laser) to display data The equipment that is projected onto external objects for imaging through corresponding electronic control circuits can be used as long as it can form projection light. It should be understood that the principle of the imaging engine of the opto-mechanical system...

Embodiment 2

[0060] See Figure 5 , which is a schematic diagram of the overall structure of the electronic device according to the second embodiment.

[0061] Both this solution and the first embodiment use a reflection unit to adjust the direction of the optical path. The difference between the two is that the two ends of the support 30' of this solution are respectively provided with a spherical matching pair (in the figure) between the housing 10 and the reflection unit 20'. not explicitly shown), and is configured such that: the reflection unit 20' at the first position and the bracket 30' are sequentially superimposed on the outer wall of the housing 10, and the mirror surface of the reflection unit 20' at the second position is located on the exit path of the projected light . In order to show the differences and connections between this solution and the first embodiment more clearly, the same components are marked with the same symbols in the drawings.

[0062] Compared with the ...

Embodiment 3

[0064] See Figure 6 and Figure 7 ,in, Figure 6 It is a schematic diagram of the overall structure of the electronic device described in the third embodiment, Figure 7 for Figure 6 A schematic diagram of a state in which the reflective unit of the electronic device shown in is in the first position.

[0065] Similarly, the electronic device described in this solution and the first and second embodiments both use the reflective unit to adjust the direction of the light path. The difference lies in that the position of the reflective unit in this solution is switched to linear displacement. Other configurations and working principles are the same as those of the previous embodiment. In this solution, a sliding fit pair is provided between the reflection unit 20" and the housing 10, and it is configured such that when it is in the first position, the reflection unit 20" is retracted to fit the outer wall of the housing 10, and the reflection unit 20" is far away from the p...

Abstract

The invention discloses electronic equipment in an integral bar shape, including: a display unit, an optical-mechanical system configured to form a projection light according to a display data signal,and an optical unit configured to adjust the projection direction of the projection light, wherein a housing of the electronic equipment on the injection path of the projection light is opened with afirst opening, the display unit is set in the direction far away from the supporting plane when the electronic equipment is arranged on a supporting plane; and the optical unit is capable of adjusting the projection light to form a projection image on the supporting plane when the plane where the display unit is located is parallel to the supporting plane so that the display unit and the supporting plane are capable of displaying the image at the same time. The electronic equipment with projection function provided by the invention is capable of adjusting the projection direction according toactual needs by structure optimization, and has good user experience.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an electronic device. Background technique [0002] A projector is a projection device used to magnify and display images, and is widely used in conferences, technical lectures, network centers, monitoring centers, and home theaters. During use, the projector first irradiates light onto the image display element to generate an image, and then projects it through the lens, so that the information is projected onto the target area (larger plane or screen), so that everyone present can clearly see the image. Images displayed in real time. [0003] See figure 1 , which shows a schematic diagram of a projection method of an existing projector. [0004] Such as figure 1 As shown, the traditional projector mainly adopts the direct projection method, and the projection screen is located in front of the lens, and viewers can only watch through the screen set in front, and ...
