[0027] like Figure 1 and Figure 2 As shown, the first embodiment of the utility model discloses a projection device, including a body shell 10, a fixing frame 20 and a light-transmitting cover plate 30. A mounting groove 11 is provided on one side of the body shell 10, the light-transmitting cover plate 30 is arranged in the mounting groove 11, and the fixing frame 20 is pressed at the edge of the light-transmitting cover plate 30 and is detachably fixedly connected in the mounting groove 11. The light-transmitting cover plate 30 can be a glass cover plate or a plastic cover plate. The body shell 10 in this embodiment is rotatably connected to the bracket 50.

[0028] The mounting slot 11 can be provided on the top of the projection device, or on the left side, right side, front side or rear side of the projection device body shell 10. The mounting slot 11 is provided with a plurality of first assembly parts, and the fixing frame 20 is provided with a plurality of second assembly parts. Each first assembly part corresponds to each second assembly part and is connected with each other so that the fixing frame 20 can be detachably fixedly connected to the mounting slot 11. Figure 2 and Figure 3 In this embodiment, the first assembly part is a buckle hole 111, and the second assembly part is a buckle 21. The buckle holes 111 are arranged at intervals along the outer periphery of the mounting groove 11 at the bottom of the mounting groove 11, and the buckles 21 are arranged at intervals along the circumference of the fixing frame 20 at the bottom of the fixing frame 20. The fixing frame 20 is snapped into the buckle holes 111 to achieve fixed assembly. At this time, the light-transmitting cover plate 30 is pressed under the fixing frame 20, and is also fixed on one side (for example, the top side) of the fuselage shell 10 together with the fixing frame 20. The shape of the fixing frame 20 is adapted to the edge contour shape of the light-transmitting cover plate 30. As shown in the figure, the shape of the light-transmitting cover plate 30 in the embodiment is a square with rounded corners, and the shape of the fixing frame 20 is also a closed square with rounded corners.

[0029] Furthermore, the projection device in this embodiment also includes a display module 40, and a sub-mounting groove 112 is provided at the bottom of the mounting groove 11, and the sub-mounting groove 112 is used to accommodate the display module 40. That is, the projection device in this embodiment is a projector with a display screen, wherein the light-transmitting cover plate 30 covers the side of the projection device where the display screen is set, that is, the display module 40 is set below the light-transmitting cover plate 30, and the area on the light-transmitting cover plate 30 corresponding to the display module 40 is the light-transmitting display area 301, and the edge of the light-transmitting cover plate 30 protruding from the display module 40 is the non-light-transmitting area 302. The display module 40 is, for example, an LCD, LED, OLED, an electronic ink screen, etc.

[0030] In this specific embodiment, the mounting groove 11 for placing the light-transmitting cover plate 30 is provided in the top shell of the projection device, and the sub-mounting groove 112 for placing the display module 40 is provided at the bottom of the mounting groove 11. The length or width of the mounting groove 11 is larger than the size of the light-transmitting cover plate 30, so as to reserve space for accommodating the fixing frame 20. The fixing frame 20 can just cover the light-transmitting cover plate 30. The shape of the fixing frame 20 is adapted to the edge gear of the light-transmitting cover plate 30. The fixing frame 20 is pressed on the edge of the light-transmitting cover plate 30 to be installed in the mounting groove 11 as a whole. Similarly, the shapes and sizes of the mounting groove 11 and the fixing frame 20 are adapted to each other, so that when the fixing frame 20 is fixedly connected in the mounting groove 11, the edge of the fixing frame 20 abuts against the groove wall of the mounting groove 11 to achieve position limiting. Among them, when the fixing frame 20 is fixedly connected in the mounting groove 11, the top surface of the fixing frame 20 is flush with the outer side surface of the body shell 10.

[0031] Specifically, combined Figure 3and Figure 5 , the inner edge of the bottom of the fixed frame 20 forms a snap-in groove 22, and the top edge of the transparent cover plate 30 forms a step surface 31. The shape and size of the step surface 31 and the snap-in groove 22 are adapted to each other. When the fixed frame 20 is pressed at the edge of the transparent cover plate 30, the snap-in groove 22 and the step surface 31 abut. Among them, the thickness of the top wall of the fixed frame 20 where the snap-in groove 22 is formed is equal to the thickness of the top layer where the transparent cover plate 30 forms the step surface 31, so that when the fixed frame 20 is pressed at the edge of the transparent cover plate 30, the top surface of the fixed frame 20 is flush with the top surface of the transparent cover plate 30. Further, the fixed frame 20 is a closed ring structure with an opening formed in the middle, and the transparent cover plate 30 extends into the opening so that the fixed frame 20 surrounds the transparent cover plate 30.

[0032] The sizes of the fixing frame 20 and the transparent cover plate 30 are not necessarily the same as those of the Figure 1 and Figure 2 The top of the entire body shell 10 is shown as being occupied, but it may also occupy only a small area on any side of the body shell 10 .

[0033] refer to Figure 4 A touch layer 32 (such as a metal mesh layer) can be disposed at the bottom of the transparent cover plate 30 to obtain the user's fingertip touch information. A display module 40 is disposed at the bottom. The display module 40 can be, for example, an LCD display, an OLED display, an electronic ink screen, etc. Figure 2 An electrical connector 41 (such as a flexible circuit board FPC) is provided at the bottom of the display module 40 . The electrical connector 41 passes through the square hole 1121 in the sub-mounting groove 112 and extends into the interior of the body shell 10 to be connected to the main control circuit board 12 .

[0034] In the above solution, the light-transmitting cover plate 30 and the display module 40 do not need to be fixed to the body shell 10 by gluing, but can be firmly fixed only by the limit of the fixing frame 20, thereby improving the convenience and stability of assembly.

[0035] like Figure 6As shown, it is a projection device disclosed in the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that, in this embodiment, the first assembly part arranged on the mounting groove 11 is a mounting hole 112, and each mounting hole 112 is arranged at the bottom of the mounting groove 11 along the outer circumference of the mounting groove 11 at intervals; the second assembly part arranged on the fixed frame 20 is a fastening column 23 and a fastener 24, and each fastening column 23 is arranged at the bottom of the fixed frame 20 along the circumferential direction of the fixed frame 20 at intervals; when the fixed frame 20 and the transparent cover plate 30 are installed in the mounting groove 11 together, the fastening column 23 can extend into the mounting hole 112, and the end face of the fastening column 23 is flush with the end face of the mounting hole 112 on one side inside the body shell 10, so that the fixing frame 20 can be fixed on the body shell 10 by locking the fastener 24 into the fastening column 23 inside the body shell 10, and making the fastener 24 abut against the outer edge of the mounting hole 112. In some embodiments, the mounting hole 112 is specifically formed by a columnar structure disposed at the bottom of the mounting groove. In this case, the height dimension of the mounting hole 112 can be larger, and correspondingly, the height of the fastening column 23 can be increased, so that a longer fastener 24 can be used to lock into the fastening column 23, further improving the assembly stability; wherein the fastener 24 can be a screw, and correspondingly, the fastening column 23 is a screw hole column. The other structures in this embodiment are the same as those in the first embodiment, and are not repeated here.
