DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Due to that the shell structure for containing numerous kinds of lenses within optic-mechanism modules provided in the present invention can be widely applied to numerous kinds of optic devices, the combined applications are also too numerous to be enumerated and described so as to disclose a preferred embodiment in an application of projector assembling technologies for representation, hence a projector directly represents the optic devices as mentioned in the following description.

Please refer to FIG. 2 to FIG. 5, wherein FIG. 2 is a partial exploded view presenting a preferred embodiment of the present invention, FIG. 3 is an internal structural view presenting the preferred embodiment of the present invention applied in a high-position optic-lens, FIG. 4 is a schematic view presenting an A-A section in FIG. 3, and FIG. 5 is a front view of an optic-lenses assembling frame in FIG. 3. As shown in the figures, a projector 200 includes an optic-mechanism module 3 and a shell structure 4 for containing the optic-mechanism module 3.

The optic-mechanism module 3 includes an optic-mechanism module body 31 and a high-position optic-lens 32 with a high-position canter axis OH, wherein the high-position optic-lens 32 is extendable and retractable from the optic-mechanism module body 31. The shell structure 4 includes a containing shell 41 and an optic-lens assembling frame 42, wherein the containing shell 41 includes a front shell 411, a bottom shell 412, and a plurality of shells as shown in FIG. 2 without marking with element numbers. The shell structure 4 is for containing the optic-mechanism module 3 and the optic-lens assembling frame 42.

The front shell 411 of the containing shell 41 is formed with an assembling hole 411a for the optic-lens assembling frame 42 being vortically assembled in. The optic-lens assembling frame 42 includes a frame body 421 and a perforating hole 422, wherein the frame body 421 includes an outer extruded ring 421a, an inner extruded ring 421b, and a connection ring 421c, and has a frame center axis O1. A distance called frame body height deviation h0 is between the frame center axis O1 and the bottom of the frame body 421, a distance called high-position height deviation h1 is between the high-position center axis OH and the bottom of the frame body 421, and the high-position height deviation h1 is greater than the frame body height deviation h0.

The outer extruded ring 421a is located out of the front shell 411 of the containing shell 41, and has an outer diameter, defined as an extruded ring outer diameter R, greater than an inner diameter, defined as an assembling hole diameter r, of the assembling hole 411a. The inner extruded ring 421b is located within the front shell 411 of the containing shell 41, and has another outer diameter equal to the extruded ring outer diameter R and greater than the assembling hole diameter r. The connection ring 421c is connected to the outer extruded ring 421a and the inner extruded ring 421c and vortically assembled into the assembling hole 411a, so that the optic-lens assembling frame 42 can be stably and vortically assembled into the assembling hole 411a. The frame body 421 has a perforating hole 422 located therein, and the perforating hole 422 defines a hole center axis O2 deviating from the frame center axis O1 as shown in FIG. 4 and FIG. 5.

When assembling the projector 200, the optic-lens assembling frame 42 should be rotated along a rotation direction I and around the rotation center of the frame center axis O1, meanwhile, the hole center axis O2 of the perforating hole 422 also rotates corresponding to the frame center axis O1 to make the hole center axis O2 rotate to a position respect to the high-position center axis OH as shown in FIG. 4, then let the high-position optic-lens 32 extracted from the optic-mechanism module body 31 be perforated into the perforating hole 422, hereafter the shell structure 4 can contain the optic-mechanism module 3 to complete the assembling operation of the projector 200.

With reference to FIG. 6 to FIG. 8, FIG. 6 is an internal structural view presenting the preferred embodiment of the present invention applied in a low-position optic-lens, FIG. 7 is a sectional view viewing from a B-B section of FIG. 6, and FIG. 8 is a front view of the optic-lens assembling frame in FIG. 6. As shown in the figures, the difference between FIG. 3 to FIG. 5 and the figures is that the shell structure 4 also can be applied for continuously containing another optic-mechanism module 3a to assemble another projector 200a.

The optic-mechanism module 3a includes an optic-mechanism module body 31a and a low-position optic-lens 32a with a low-position canter axis OL, wherein the low-position optic-lens 32a is extendable and retractable from the optic-mechanism module body 31a. A distance called frame body height deviation is between the frame center axis and the bottom of the frame body 421, a distance called low-position height deviation is between the low-position center axis and the bottom of the frame body 421, and the low-position height deviation h2 is less than the frame body height deviation hO.

When assembling the projector 200a, the optic-lens assembling frame 42 should be rotated along the rotation direction I and around the rotation center of the frame center axis O1. Simultaneously, the hole center axis O2 of the perforating hole 422 also rotates corresponding to the frame center axis O1 to make the hole center axis O2 rotate to a position corresponding to the low-position center axis OL as shown in FIG. 7, then let the low-position optic-lens 32a extracted from the optic-mechanism module body 31a be perforated into the perforating hole 422, hereafter the shell structure 4 can contain the optic-mechanism module 3a to complete the assembling operation of the projector 200a.

In practice, due to that it is necessary to rotate the optic-lens assembling frame 42 to adjust the position of the perforating hole 422 when the shell structure 4 contains the optic-mechanism modules 3 and 3a, the peripheral of the outer extruded ring 421a can be pressed with rough patterns, so that users can clip the outer extruded ring 421a to conveniently rotate the optic-lens assembling frame 42. Meanwhile, the high-position optic-lens 32 is fit for a first digital micromirror device (DMD), the low-position optic-lens 32a is fit for a second DMD different from the first DMD in dimensions.

Besides, the low-position optic-lens 32a as mentioned above usually can be a lens of SVGA optic-mechanism module specified in a computer analysis standard specification provided by Video Electronics Standards Association (VESA), the high-position optic-lens 32 usually can be another lens of XGA optic-mechanism module specified in the computer analysis standard specification provided by VESA, the address of VESA is 860 Hillview Ct. Suite 150 Milpitas, Calif. 95035, the telephone number of VESA is 408-957-9270, and the fax number of VESA is 480-957-9277.

After going through above description, people skilled in the field of assembling optical device technology can easily realize that the perforating hole 422 provided for the optic-lenses, such as the high-position optic-lens 32 and the low-position optic-lens 32a as disclosed in the present invention, perforating through is able to be adjusted to different positions for different optic-mechanism modules by the means of the present invention. Therefore, the present invention can provide stable support to the lenses, either the high-position lens 32 or the low-position lens 32a. Hence, the manufacturing cost of the shell structure 4 and the assembling cost of the projector 200 or 200a are saved, and there is no need to manufacture additional dies for the front shell 411. By the way, it can also solve the light interference problem of images caused by unnecessary light leaking out of the optic-mechanism module.

Although the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
