Abstract

A portable electronic device comprises a body, a screen, a projection module and a knob. The body has two adjacent shell walls, and each shell wall has a projection window. A screen is pivoted on the machine body, so that the screen rotates relative to the machine body and is selectively attached to the machine body or forms an included angle with the machine body. A projection module is pivoted in the machine body and is provided with a projection lens. A knob is pivoted on the bearing surface of the machine body and penetrates through the machine body to be connected with the projection module. When the knob rotates, the projection module synchronously rotates to align the projection lens to one of the two projection windows.

Description

Portable electronic device with projection function

technical field

The invention relates to an electronic device, in particular to a portable electronic device with projection function.

Background technique

It is known that when a notebook computer is used to make a presentation, an external projector is usually required to project the information displayed on the notebook computer screen onto a larger screen. However, unless the presentation site is equipped with a projector, the presentation personnel need to bring their own notebook computers and projectors, which causes a certain degree of inconvenience for the presentation personnel.

Contents of the invention

Therefore, the object of the present invention is to provide a portable electronic device with projection function.

According to the above objective of the present invention, a projection device is proposed, which includes a body, a projection module, and a knob. A machine body has two shell walls adjacent to each other, and each of the two shell walls has a projection window. A projection module is hinged in the body and has a projection lens. A knob is pivotally connected to the carrying surface of the body and passes through the body to connect with the projection module. When the knob is turned, the projection module rotates synchronously to align its projection lens with one of the two projection windows.

Detailed ways

Please refer to FIG. 1 , which is a side view of a portable electronic device according to a preferred embodiment of the present invention. The portable electronic device 100 has a body 102 and a screen 104 (such as a notebook computer), and is equipped with a projection function, so that the information displayed on the screen 104 can be projected out from the projection window 106a or 106b. The screen 104 is pivotally connected to the body 102 , so that the screen 104 rotates relative to the body 102 in the direction of the arrow in the figure and selectively attaches to the body 102 or forms an included angle with the body 102 . In addition, the portable electronic device 100 further has a rotating plate 108 for supporting the body 102 to different inclinations so that the projection angle can be adjusted.

Please refer to FIG. 2 , which shows a bottom view of the portable electronic device in FIG. 1 . In addition to adjusting the projection angle, the rotating plate 108 located on the carrying surface 102a (or referred to as the bottom surface) can also switch the projection direction. The user can turn the rotary plate 108 to switch the projection to the projection window 106 a or the projection window 106 b to project the body 102 . Taking Fig. 3 as an example, the original projection direction is the projection window 106b (refer to the (a) view of Fig. 3), and the rotating plate 108 is erected from the state of being attached to the rotating disk 107 to facilitate rotation (refer to Fig. 3 (b) view), and then rotate the rotary plate 108 by 90 degrees so that the projection direction is the projection window 106a (see (c) view of FIG. 3 ).

Please refer to FIG. 4 , which shows a disassembled view of the knob. The knob includes a dial 107 and a dial 108 . The rotating plate 108 is pivotally connected to the circular rotating disk 107 , and the knob after the two are assembled is pivotally connected to the bearing surface 102 a of the body 102 . In order to enable the rotary plate 108 to perform a multi-stage temporary positioning function relative to the rotary plate 107, the pivotal axis surfaces 108a/108b of the rotary plate 108 and the pivotal axis surfaces 107a/107b of the rotary plate 107 are designed as wave surfaces. When the pivotal surface 108a is connected to the pivotal surface 107a; the pivotal surface 108b is connected to the pivotal surface 107b, the crests and troughs of the pivotal surfaces engage with each other to provide sufficient frictional force for positioning.

Please refer to FIG. 5 and FIG. 6 , which respectively illustrate two projection modes of the projection module in the portable electronic device. When the projection lens 110a of the projection module 110 (refer to FIG. 5 and FIG. 7 ) is aligned with the projection window 106a, the state of the rotating plate 108 is the bottom view of FIG. 3 . When the projection lens 110a (refer to FIG. 6 and FIG. 7 ) of the projection module 110 is aligned with the projection window 106b, the state of the rotating plate 108 is the middle view of FIG. 3 . The projection window 106b can be any transparent material (such as transparent glass).

Please refer to FIG. 7 , which shows an exploded view of the projection mechanism in the portable electronic device. How the projection module 110 is pivotally connected in the body 102 will be described below. A pivot member 112 supports the projection module 110 with its disc portion, and passes through the pivot hole 114 a on the body 102 with its pivot shaft 112 a. The pivot shaft 112 a is fixed in the pivot hole 107 c of the turntable 107 at the same time, so that the turntable 107 , the pivot member 112 and the projection module 110 can be pivotally connected to the body 102 and rotate synchronously. The rotating plate 108 is pivotally connected to the rotating disk 107 (also referring to FIG. 4 ) so as to rotate synchronously with the rotating disk 107 . The disc portion of the pivot member 112 has three positioning holes 112c, and a positioning piece 112b extends from the side end. The inner surface of the body 102 has two positioning protrusions 114b and a stopper 114c. When the pivotal member 112 rotates on the pivotal shaft 112a, the positioning hole 112c and the positioning piece 112b of the pivotal member 112 interfere with the positioning bump 114b and the stopper 114c of the body 102, so that the rotating plate 108 can conveniently place the projection module Projection lens 110a of 110 is aligned with projection windows 106a/106b on two adjacent housing walls 102b/102c. The blocking block 114c is used to block the positioning piece 112b, so that the pivot member 112 will not rotate excessively. When the positioning protrusion 114b is snapped into the positioning hole 112c, the pivot member 112 is temporarily positioned, and the projection lens 110a of the projection module 110 is aligned with the projection window 106a or the projection window 106b.

From the above preferred embodiments of the present invention, it can be known that the application of the portable electronic device with projection function of the present invention allows the user to execute the work of the presentation without carrying an additional projector. In addition, the user can also adjust the projection direction and angle of the portable electronic device to achieve the best projection effect.

Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and modifications without departing from the spirit and scope of the present invention. , so the protection scope of the present invention shall prevail as defined by the claims of the present application.
