【Detailed ways】

The aforementioned and other technical contents, features and effects 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 some components of the projector of FIG. 1 . FIG. 3 is a perspective view of the cover shown in FIG. 1 being opened. Referring to FIGS. 1 to 3 , the projector 100 of this embodiment includes a housing 110 , a lens 120 , a locking member 130 and a cover 140 . The housing 110 has a side 112 , a first opening 114 and a second opening 116 . The first opening 114 and the second opening 116 are located on the side surface 112 .

The lens 120 is disposed in the casing 110 and exposed by the first opening 114 . The locking member 130 is disposed in the housing 110 and has a limiting portion 132 and a push handle 134 connected thereto, wherein the push handle 134 is located opposite to the second opening 116 . The cover 140 is fixed to the housing 110 in a locking manner to cover the second opening 116 . As shown in FIG. 2 , when the push handle 134 is at the position shown by the solid line, the limiter 132 will limit the lens 120 to fix the lens 120 , and when the push handle 134 is at the position shown by the dotted line , the limit of the lens 120 by the limit part 132 will be released.

FIG. 4 is a schematic diagram of the action of the push handle in FIG. 3 . FIG. 5 is a schematic diagram of the lens in FIG. 4 being taken out of the housing. When the user wants to disassemble the lens 120, the cover body 140 of FIG. 1 can be opened to the state shown in FIG. 3, and the push handle 134 can be moved from the position shown in FIG. 134) Push to the position shown in FIG. 4 (corresponding to the push handle 134 shown in dotted line in FIG. 2). At this time, the limit of the lens 120 by the limit portion 132 will be released, and the lens 120 can be removed from the casing 110 as shown in FIG. 5 .

Since the cover 140 of this embodiment covers the casing 110 in a snap-fitting manner, rather than being fixed to the casing 110 in a screw-lock manner, when the user wants to disassemble the lens 120, the user can directly open the cover 140 and push Push the handle 134 to release the limit of the limit portion 132 to the lens 120, so that the lens 120 can be disassembled more conveniently. In addition, the first opening 114 for exposing the lens 120 and the second opening 116 for exposing the push handle 134 are located on the same side (side 112) of the housing 110, which can further improve the convenience of the user when disassembling the lens 120. .

FIG. 6 is a partially enlarged view of the projector of FIG. 3 . Please refer to FIG. 6, the cover body 140 of this embodiment has a groove 142. When the push handle 134 is located at the position shown in FIG. 3 and the cover body 140 covers the second opening 116 as shown in FIG. The groove 142 is limited to the position shown in FIG. 3 . Thereby, the cover body 140 can restrict the push handle 134 by the groove 142 , so as to prevent the locking member 130 from unintentionally releasing the restriction on the lens 120 due to shaking of the projector 100 or other factors.

The projector 100 further includes flexible members 150 (shown as two, but the number is not limited). The material of the flexible members 150 is, for example, rubber, and the two ends of the flexible members are ball-connected to the shell 110 and the cover 140 respectively, so as to The cover 140 is movably connected to the casing 110 so as not to fall off from the casing 110 . In addition, the shell 110 has a notch 118 on the side 112 , and the second opening 116 is formed in the notch 118 . The peripheral edge of the cover 140 has an elastic structure 110 a, and the material of the elastic structure 110 a is rubber, for example. When the cover 140 covers the second opening 116 as shown in FIG. 1 , the elastic structure 110 a fits into the notch 118 , and the cover 140 is fastened to the notch 118 by the elastic deformation of the elastic structure 110 a. In addition, the side of the cover 140 has protruding points 144 (two are shown). When the cover 140 covers the second opening 116 as shown in FIG. The cover body 140 is further fixed on the casing 110 .

FIG. 7 is a partial structural perspective view of the housing of FIG. 1 . Please refer to FIG. 6 and FIG. 7 , in this embodiment, one end of the locking member 130 has a bearing surface 136, the push handle 134 is connected to the bearing surface 136, and the bearing surface 136 is bearing against the inner surface 110b of the housing 110, The bearing surface 136 is partially exposed by the second opening 116 . Thereby, when the push handle 134 is pushed between the position shown in FIG. 3 and the position shown in FIG. 4 , the abutment surface 136 of the locking member 130 will abut against the inner surface 110b, so that the whole structure will relatively stable.

To sum up, in the above-mentioned embodiments of the present invention, the cover system is fixed to the housing in a locking manner to cover the second opening. When the user wants to disassemble the lens, he can directly open the cover body and push the push handle to release the limitation of the lens by the limiting part, so that the disassembly and assembly of the lens is more convenient. In addition, the first opening for exposing the lens and the second opening for exposing the push handle are located on the same side of the casing, which further improves the convenience of the user when disassembling the lens.

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.
