Description

Projector housing

【Technical field】

The present invention relates to a housing, and in particular to a projector with such a housing.

【Background technique】

A projector is a display device used to produce large-scale images. The imaging principle of the projector is to convert the illumination beam generated by the light source module into an image beam through the light valve, and then project the image beam onto the screen or wall through the lens to form an image. With the advancement of projection technology and the reduction of manufacturing costs, the use of projectors has gradually expanded from commercial use to home use.

In order to make the light source suitable for maintenance and replacement, an opening facing the light source is generally provided on the top surface of the projector casing, and the opening is covered by a cover, and the cover is fixed on the Projector housing. When the user intends to maintain or replace the light source, the screw must be removed first, and then the cover body can be removed to operate through the opening. This arrangement makes the maintenance and replacement of the light source more time-consuming.

【Detailed ways】

The aforementioned and other technical contents, features and functions of the present invention will be clearly presented in the following detailed descriptions of multiple embodiments with reference to the drawings. The directional terms mentioned in the following embodiments, such as "upper", "lower", "front", "rear", "left", "right", etc., are only referring to the directions of the attached drawings. Accordingly, the directional terms are used to illustrate, not to limit, the invention.

FIG. 1 is a perspective view of a projector according to an embodiment of the present invention. FIG. 2 is a perspective view of the exposure opening of the cover in FIG. 1 . FIG. 3 is a perspective view of the projector of FIG. 2 at another viewing angle. Please refer to FIG. 1 to FIG. 3 , the projector 100 of this embodiment includes a main casing 110 and a light source 120 . The main casing 110 has an opening 112 and at least one slide slot 114 (two are shown), and the slide slot 114 is located on the inner wall of the opening 112 . The light source 120 is disposed in the main housing 110 and exposed by the opening 112 .

FIG. 4 is a perspective view of the cover and the sliding part of FIG. 1 . Referring to FIGS. 2 to 4 , the projector 100 further includes at least one sliding member 130 (two are shown) and a cover 140 , and the sliding member 130 is slidably disposed on the slide slot 114 . The cover 140 is connected to the slider 130, wherein the slider 130 is suitable for sliding between two ends of the chute 114, so that the cover 140 covers the opening 112 (as shown in FIG. 1 ) or exposes the opening 112 (as shown in FIG. 2 and Figure 3). With this arrangement, when the user intends to replace or maintain the light source 120 , the user can directly push the cover 140 to expose the opening 112 , making the replacement or maintenance of the light source 120 more convenient. In this embodiment, the main casing 110 and the cover 140 jointly form a casing for protecting internal components of the projector 100 .

Referring to FIG. 1 and FIG. 2 , in detail, the main housing 110 has an adjacent top surface 110 a and a side surface 110 b, and the opening 112 extends from the top surface 110 a to the side surface 110 b. The cover body 140 includes a connected main body portion 142 and an extension portion 144 . When the cover 140 covers the opening 112 as shown in FIG. 1 , the main body portion 142 covers the portion of the opening 112 located on the top surface 110 a, and the extension portion 144 covers the portion of the opening 112 located on the side surface 110 b. When the cover 140 exposes the opening 112 as shown in FIG. 2 , the main body 142 is parallel to the side 110 b, and the extension 144 is located at a bottom 118 of the main housing 110 . Thereby, regardless of whether the cover 140 covers the opening 112 as shown in FIG. 1 or exposes the opening 112 as shown in FIG. Need space.

Please refer to FIG. 4 , the sliding member 130 of this embodiment is, for example, a screw and includes a head 132 and a shaft 134 . The shaft portion 134 is connected to the cover body 140 and passes through the sliding slot 114 (shown in FIGS. 2 and 3 ). The head 132 is connected to the shaft portion 134 and located in the sliding slot 114 . FIG. 5 is a schematic partial cross-sectional view of the sliding member 130 and the slide groove 114 in FIG. 3 . Please refer to FIG. 5, in this embodiment, the outer diameter of the head 132 can be designed to be larger than the width of the chute 114, so that the head 132 is suitable to be limited in the chute 114, so that the slider 130 will not slip from the slide. The groove 114 comes off.

Please refer to FIG. 3 and FIG. 4 , the bottom surface of the cover body 140 in this embodiment has at least one first fixing member 140a (shown as a plurality), and the main housing 110 has at least one second fixing member 116 at the edge of the opening 112 ( are shown as multiples). When the cover 140 covers the opening 112 , the first fixing part 140 a and the second fixing part 116 are adapted to produce structural interference to fix the position of the cover 140 and prevent the cover 140 from unintended displacement due to shaking of the projector 100 . In addition, please refer to FIG. 1 , the housing 100 of this embodiment further includes at least one locking piece 150 (two are shown), when the cover 140 covers the opening 112, the cover 140 can be locked on the cover 140 by the locking piece 150 The main housing 110 is used to further fix the position of the cover 140 .

Please refer to FIG. 3 , in the present embodiment, the end 114a of the slide groove 114 extends away from the top surface 110a. Thus, when the slider 130 slides along the slide groove 114 to the end 114 a, the cover 140 is driven to be coplanar with the top surface 110 a and cover the opening 112 . In other words, there is a gap between the cover 140 and the main casing 110 before the sliding member 130 reaches the end 114 a, so as to prevent the cover 140 from contacting the main casing 110 and being hindered when the user pushes the cover 140 .

To sum up, in the above embodiments of the present invention, the cover is adapted to slide relative to the main casing to cover or expose the opening. When the user wants to replace or maintain the light source, he can directly push the cover body to expose the opening of the cover body, so that the replacement or maintenance of the light source is more convenient. In addition, the cover body can be designed to remain attached to the main casing when covering the opening or exposing the opening, so as to save the space required for placing the projector.

The above is only a preferred embodiment of the present invention, and should not limit the scope of the present invention, that is, all simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the description of the invention are still the same. It is within the scope covered by the patent of the present invention. In addition, any embodiment or scope of claims of the present invention does not necessarily achieve all the objectives or advantages or features disclosed in the present invention.
