The optical-mechanical module 100 further includes a plurality of first locking holes 106, and the color wheel module 200 further includes a plurality of second locking holes 206 and a plurality of locking members (not shown), such as screws.

Referring to fig. 5, after the color wheel module 200 and the optical-mechanical module 100 are assembled, the color wheel 201 is accommodated in the groove 103; one of the first electrical connection structure 102 and the second electrical connection structure 203 is a sliding clamping connector, and the other is a fixed connector; the sliding clamping connector is movable relative to the fixed connector to adjust the relative positions of the first electrical connection structure 102 and the second electrical connection structure 203 to be plugged into each other to form an electrical connection.
Referring to fig. 2, fig. 3 and fig. 5, in the present embodiment, the optical-mechanical module 100 is provided with a first fixing plate 107, and the first electrical connection structure 102 is fixedly disposed on the first fixing plate 107, wherein the first fixing plate 107 is provided with a fixing hole 108, and the first fixing plate 107 is fixed on the optical-mechanical housing 101 by a fixing member, such as a screw or a fastener.

That is, in the present embodiment, the first electrical connection structure 102 is a fixed connector, and the second electrical connection structure 203 is a sliding clamping connector. Moreover, when the second electrical connection structure 203 is slidably disposed on the color wheel housing 202, the opening of the optical module 100 may be smaller, as shown in fig. 3, an end of the color wheel housing 202 may be disposed in an L-shaped structure to match the first electrical connection structure 102 on the optical module 100.

That is, in the present embodiment, the position of the second electrical connecting structure 203 on the second fixing plate 207 can be adjusted in two mutually perpendicular directions D1 and D2, further improving operability.
There are various ways to realize the sliding of the second electrical connection structure 203 on the second fixing plate 207, wherein one way is to provide a slide rail on the second fixing plate 207 along the first direction D1, and form a slide groove on the surface of the second electrical connection structure 203 facing the second fixing plate 207, or the positions of the slide groove and the slide rail are reversed, so that the second electrical connection structure 203 can slide on the second fixing plate 207.
In addition, the optical-mechanical module 100 further includes at least one first positioning structure 105 disposed on the optical-mechanical housing 101; the color wheel module 200 further includes at least one second positioning structure 205 disposed on the color wheel housing 202; the color wheel module 200 and the optical module 100 are combined and positioned by at least one first positioning structure 105 and at least one second positioning structure 205.

Since the first positioning structure 105 and the second positioning structure 205 can correspond to each other, when the color wheel module 200 is assembled on the optical module 100, the color wheel module 200 can be quickly and accurately positioned by the first positioning structure 105 and the second positioning structure 205, and the color wheel module 200 can be easily clamped in the groove 103 of the optical module 100. Since the optical-mechanical module 100 is a reference for all optical elements of the projection apparatus 10, the positioning is directly performed by the first positioning structure 105 on the optical-mechanical module 100, so that the color wheel module 200 and the optical elements in the optical-mechanical module 100 can be aligned more accurately. Compared with the comparative example in which the color wheel module is fixed to the housing of the projection device, the generation of the accumulated assembly tolerance can be avoided.
In an embodiment, after the color wheel module 200 is engaged with the optical-mechanical module 100, the plane plate 204 covers the optical-mechanical housing 101, so that the color wheel housing 202 seals the groove 103.
In one embodiment, when the first positioning structure 105 is a positioning pin, the second positioning structure 205 is a positioning hole, and the positioning pin corresponds to the positioning hole; when the first positioning structure 105 is a positioning hole, the second positioning structure 205 is a positioning pin, and the positioning pin corresponds to the positioning hole.

In one embodiment, the positioning pin has a circular cross section, and the positioning hole is a circular hole.
In one embodiment, the positioning pin has a non-circular cross section, and the positioning hole is a non-circular hole. For example, the cross-section of the retaining pin may be triangular, rectangular, cross-shaped, and the like. The positioning holes may be triangular holes, rectangular holes, cross-shaped holes, and the like. When the color wheel module 200 and the optical module 100 are positioned by the first positioning structure 105 and the second positioning structure 205, the positioning pin with the non-circular cross section and the positioning hole with the non-circular hole can limit the movement and rotation between the optical module 100 and the color wheel module 200 on the X-Y plane compared to the positioning pin with the circular cross section and the positioning hole with the circular hole.
In one embodiment, the number of first positioning structures 105 is 2 or more than 2, the number of second positioning structures 205 is 2 or more than 2, and each first positioning structure 105 corresponds to each second positioning structure 205.
In an embodiment, the light provided by the light source can be accurately focused on the color wheel 201 of the color wheel module 200 for color separation, and an image is presented through the light pipe 104 and the optical elements in the accommodating space, such as the DMD, and then through the lens.
In summary, one of the two electrical connection structures of the optical module and the color wheel module of the present invention employs a sliding clamping connector (or contact), and the other employs a fixed connector (or contact), so that the sliding clamping connector is inserted into the fixed contact and clamped, thereby avoiding the problem of poor contact of the thimble. In addition, the color wheel module is positioned in the groove of the optical machine module by the first positioning structure on the optical machine module and the second positioning structure on the color wheel module, so that the color wheel module has the advantages of easiness in installation and high accuracy, and can avoid the damage of the electric connection structure.
